Description

The present invention relates to a cleaning device.

Conventionally, an ultrasonic cosmetic device has been known in which a metallic vibration plate that vibrates with ultrasonic waves is brought into contact with the skin, and a pulsating voltage synchronized with the vibration of the vibration plate is applied between the vibration plate and the skin, and the vibration plate is moved along the surface of the skin (see Patent Document 1).
Such ultrasonic cosmetic devices can emulsify and remove sebum from the surface of the skin when used in combination with water or a cosmetic serum, but they have difficulty removing keratin plugs that clog pores.

In light of the above circumstances, the present invention aims to provide a cleaner that can easily remove not only sebum from the skin surface, but also blackheads that have clogged pores.

One aspect of the present invention provides a cleaner used to clean a user's skin surface. This cleaner comprises a cleaner main body, a vibration mechanism, and a supply mechanism. The vibration mechanism has a vibrating body that comes into contact with the skin surface and applies vibrations to the skin surface. The supply mechanism has a supply port that supplies a liquid or gel-like cleanser to the skin surface.

This aspect provides a cleaner that can easily remove not only sebum from the skin surface, but also blackheads that have clogged pores.

1 and the like, is used to cleanse the skin of a user. This cleaner 1 comprises a cleaner body 2 and a head unit 3 that is detachably attached to the cleaner body 2.
In this embodiment, the head unit 3 includes a head unit 3A for use on skin surfaces with a relatively large area (e.g., cheeks) and a head unit 3B for use on skin surfaces with a relatively small area (e.g., nose). That is, the washer 1 shown in Fig. 1 etc. includes two (plural) head units 3A and 3B of different sizes, and is configured to use by attaching one of the two head units 3A and 3B to the washer main body 2. With this configuration, it is possible to perform appropriate treatment depending on the area of the skin surface.
The head portion 3 may have one or more other head portions of different sizes from the head portions 3A and 3B. The multiple head portions 3 may have different shapes depending on the skin surface to be used.

In the following description, when there is no need to particularly distinguish between the head portion 3A and the head portion 3B, they will be collectively referred to simply as "head portion 3."
1 and 2 is an assembly that includes an annular sealing member 31 and a cup-shaped (cylindrical with a bottom) vibrating body 32 that is disposed inside the sealing member 31. The inner surface of the vibrating body 32 is configured as a curved concave surface that is hemispherical.
The seal member 31 can be made of a rubber material such as acrylonitrile butadiene rubber (NBR), silicone rubber, acrylic rubber, or ethylene propylene rubber.
The sealing member 31 is configured to form a closed space between the skin surface and the sealing member 31 by contacting the skin surface so as to close the opening. This closed space communicates with a supply port 611 and a suction port 711, which will be described later.

The vibrating body 32 can be made of a metal material such as stainless steel, copper, aluminum or an aluminum alloy, a titanium alloy, or a die steel.
The outer diameter of the vibrating body 32 of the head portion 3A is preferably about 16 mm or more and 25 mm or less.
On the other hand, it is preferable that the outer diameter of the vibrating body 32 of the head portion 3B is approximately 10 mm or more and 15 mm or less.
It is preferable that one or both of the head unit 3 and the washer main body 2 have a fixing mechanism (not shown) for fixing them to each other.

The washer main body 2 has an upper case 21 and a lower case 22 .
The upper case 21 is formed of a cylindrical member with a bottom (a cylinder having a ceiling), and has two operation buttons 211 and 212 on the front surface. For example, the operation button 211 is a button for turning the power on and off, and the operation button 212 is a button for selecting and determining the operation mode of the head unit 3. Note that the operation buttons 211 and 212 may each have other functions.
An upper opening 213 is formed in the ceiling of the upper case 21, and an ultrasonic vibrator 4 is disposed inside the upper opening 213 to close the upper opening 213. When the head unit 3 is attached to the cleaner body 2, the vibrating body 32 of the head unit 3 is configured to come into contact with the ultrasonic vibrator 4. This allows the ultrasonic vibrator 4 to apply ultrasonic vibrations to the vibrating body 32.
Furthermore, a light source may be provided on the ceiling of the upper case 21 around the periphery of the upper opening 213. Such a light source may be used for decorative purposes or to visually indicate the usage status (treatment status) of the cleaner 1. Furthermore, by providing a blue LED as the light source, it is possible to expect a bactericidal effect on the skin surface, a soothing effect against inflammation, and the like.

Furthermore, a long hand electrode 5 is provided on the rear surface of the upper case 21 along the height direction of the upper case 21. With this configuration, when a user grips the washer main body 2, the user's hand can reliably contact the hand electrode 5.
A partition wall 214 is provided midway along the height of the upper case 21 to divide the internal space into upper and lower sections. This partition wall 214 ensures that the upper internal space is liquid-tight. Various electrical mechanisms are arranged in the upper internal space of the upper case 21.
The lower case 22 is detachably attached to close the lower opening 210 of the upper case 21 .

2, the lower case 22 has a disk-shaped bottom 221 and a cylindrical insertion portion 222 standing upright from the bottom 221. The lower case 22 can be attached to the upper case 21 by inserting the insertion portion 222 into the lower opening 210 of the upper case 21 and fitting it into the inner periphery of the upper case 21.
The insertion portion 222 is disposed inside the outer edge of the bottom portion 221. Therefore, when the insertion portion 222 is inserted into the lower opening 210 of the upper case 21, the outer periphery of the bottom portion 221 abuts against the lower end of the upper case 21, thereby positioning the lower case 22 relative to the upper case 21.
The cleaner body 2 may also be provided with a separation prevention mechanism that prevents the lower case 22 from separating from the upper case 21 in this state. Such a separation prevention mechanism may be configured, for example, with a claw portion (protrusion) provided on one of the upper case 21 and the lower case 22, and a recess or groove that engages with the claw portion provided on the other.

Inside the insertion section 222 of the lower case 22, there are provided a first storage container (detergent storage section) 231 for storing the detergent to be supplied to the skin surface, and a second storage container 232 for storing the detergent recovered from the skin surface.
The first storage container 231 and the second storage container 232 are each formed of a cylindrical member with a bottom. When the lower case 22 is attached to the upper case 21, the upper openings of the first storage container 231 and the second storage container 232 are each configured to be closed by a partition wall 214. From the viewpoint of ensuring liquid-tightness between the upper openings of the first storage container 231 and the second storage container 232 and the partition wall 214, a rubber material is suitable as a constituent material for the partition wall 214.
Although there are no particular limitations on the external shapes of the first storage container 231 and the second storage container 232, in this embodiment, a semicircular shape is preferable, which allows the capacity of each of the first storage container 231 and the second storage container 232 to be sufficiently large.

At least the first storage container 231 may be configured as a cartridge type that is detachable from the lower case 22 .
A liquid or gel-like detergent (preferably a liquid detergent in this embodiment) is stored in the first storage container 231. The detergent preferably contains cleaning water or a peeling agent.
The water used for washing is not particularly limited, but examples thereof include tap water, pure water, ultrapure water, distilled water, ion-exchanged water, and RO water.
The peeling agent is not particularly limited, but examples thereof include an aqueous solution containing at least one of α-hydroxy acids (lactic acid, glycolic acid, etc.), β-hydroxy acids (salicylic acid, etc.), and protein hydrolase (protease).

Alpha-hydroxy acids and beta-hydroxy acids each have the effect of degrading desmosomes, which are adhesive components of the stratum corneum, and removing the stratum corneum, thereby facilitating the expulsion of keratin plugs from pores.
Furthermore, proteolytic enzymes have the effect of breaking down keratin plugs and promoting their discharge from pores.
The content of these ingredients in the peeling agent is adjusted taking into consideration the above-mentioned effects and irritation to the skin surface.
To make the detergent gel, a gelling agent such as pectin, carrageenan, xanthan gum, guar gum, gum arabic, methylcellulose, or gelatin may be added to the liquid detergent.
The material of which the washer body 2 is made is not particularly limited, but examples thereof include hard resin materials such as polycarbonate, polypropylene, polystyrene, and ABS resin.

As shown in FIG. 2, the washer 1 further includes a supply mechanism 6 and a suction mechanism 7 .
The supply mechanism 6 has a through-hole 61 that penetrates the bottom of the vibrating body 32 in the thickness direction, and a supply tube (supply flow path) 62 made of, for example, polyvinyl chloride.
The through-hole 61 opens to the center of the bottom surface of the vibrating body 32, forming a supply port 611 for supplying the cleanser to the skin surface. That is, the supply mechanism 6 has the supply port 611 for supplying the cleanser to the skin surface.
The supply tube 62 is fixed with its upper end passing through the ultrasonic vibrator 4. As shown in Fig. 2, when the head unit 3 is attached to the cleaning device main body 2, the through-hole 61 and the supply tube 62 communicate with each other. The supply tube 62 also passes through the partition wall 214, and is configured so that its lower end is immersed in the cleaning agent stored in the first storage container 231 when the lower case 22 is attached to the upper case 21. With this configuration, the supply tube 62 communicates between the supply port 611 and the first storage container 231.

On the other hand, the suction mechanism 7 has a through-hole 71 that penetrates the bottom of the vibrating body 32 in the thickness direction, a suction tube (suction flow path) 72 made of, for example, polyvinyl chloride, and a pump 73 that reduces the pressure in the suction tube 72. In this embodiment, the pump 73 is provided midway along the suction tube 72.
The through-hole 71 opens to the center of the bottom surface of the vibrator 32 and forms a suction port 711 that sucks in the cleanser supplied to the skin surface. That is, the suction mechanism 7 has the suction port 711 that sucks in the cleanser supplied to the skin surface.
The suction tube 72 is fixed with its upper end passing through the ultrasonic vibrator 4. As shown in Figure 2, when the head unit 3 is attached to the washer body 2, the through-hole 71 and the suction tube 72 communicate with each other. The suction tube 72 also passes through the partition wall 214, and is configured so that its lower end is located inside the second storage container 232 when the lower case 22 is attached to the upper case 21. With this configuration, the suction tube 72 communicates between the suction port 711 and the second storage container 232.
Therefore, in this embodiment, the seal member 31 is provided so as to surround the supply port 611 and the suction port 711 .

With the above configuration, by bringing seal member 31 into contact with the skin surface, supply tube 62 and suction tube 72 communicate with each other through a closed space (sealed space) defined by seal member 31 and the skin surface. In this state, by operating pump 73, the cleanser is supplied to the skin surface sequentially through supply tube 62, through-hole 61, and supply port 611 (i.e., from supply mechanism 6).
The cleanser supplied to the skin surface passes through the suction port 711 , the through-hole 71 and the suction tube 72 in this order, and is collected in the second storage container 232 .

Next, the electrical configuration (power supply device 8) of the cleaner 1 will be described.
The power supply device 8 shown in Figure 3 has a power supply unit 80, a power supply circuit 81, a CPU 82, an oscillator circuit 83, a variable resistor 84, a drive circuit 85, a transformer 86, a control circuit 87, and an output circuit 88.
The power supply unit 80 can be configured, for example, from a primary battery such as a dry cell, a solar cell, or a fuel cell, a secondary battery such as a lithium ion battery, or an adapter for connecting to an external power source.
The CPU 82 includes a processing element and a storage element.

The arithmetic element is composed of, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), etc. The arithmetic element realizes various functions related to the cleaner 1 by reading out predetermined programs stored in the memory element. In other words, information processing by the software stored in the memory element is specifically realized by the arithmetic element.
The number of computing elements is not limited to one, and multiple computing elements may be provided for each function. A combination of these may also be used. It is particularly preferable to provide a computing element for charge control of the vibrator 32, separate from the computing element for controlling the operation of the ultrasonic vibrator 4.

The memory element stores various pieces of information as defined above, and may be implemented as a storage device such as a solid state drive (SSD) that stores various programs related to the cleaner 1 executed by the computing element, or as a memory such as a random access memory (RAM) that stores temporarily required information related to program operations (arguments, arrays, etc.).
The storage element also stores various programs and variables related to the cleaner 1 that are executed by the arithmetic element.

A voltage is supplied to the ultrasonic vibrators 4 from a power supply circuit 81 via an oscillation power supply circuit consisting of a transmission circuit 83, a drive circuit 85, and a transformer 86. The oscillation frequency of this voltage is controlled by a transmission signal from the transmission circuit 83. A variable resistor 84 is attached to this transmission circuit 83, and this variable resistor 84 can be used to adjust the transmission frequency of the transmission circuit 83 for each ultrasonic vibrator 4 so that it matches the natural vibration of the ultrasonic vibrator 4.
In this embodiment, the vibration imparting mechanism is made up of the vibrating body 32, the ultrasonic vibrator 4, the power supply circuit 81, the transmitting circuit 83, the drive circuit 85, and the transformer 86. That is, the cleaner 1 further includes a vibration imparting mechanism, which has the vibrating body 32 that comes into contact with the skin surface and imparts vibrations to the skin surface.

The power supply circuit 81 also supplies a voltage to the vibrating body 32 and the hand electrode 5 via an output circuit 88. The output cycle and polarity (positive charge or negative charge) of this output circuit 88 are adjusted by a control circuit 87.
In this embodiment, the charging mechanism is made up of the vibration body 32, the hand electrode 5, the power supply circuit 81, the output circuit 88, and the control circuit 87. That is, the cleaner 1 further includes a charging mechanism, which is configured to charge the vibration body 32 positively or negatively. The position of the hand electrode 5 is not limited to that shown in the figure. Furthermore, the overall configuration of the charging mechanism is not limited to the configuration shown in the figure, as long as it can charge the vibration body 32 positively or negatively.
The vibrator 32 can be charged by applying a voltage to the vibrator 32 in contact with the skin surface and the hand electrode 5 in contact with the handle of the cleaner main body 2. When the vibrator 32 is positively charged, it can exert the action of expelling proteins and the like present in pores (ion extraction action). On the other hand, when the vibrator 32 is negatively charged, it can exert the action of injecting ions into pores (ion introduction action).

Next, the method of use (function) of the cleaner 1 will be described.
[1] First, the operation button 211 of the cleaner main body 2 is pressed to turn on the power. This activates the vibration mechanism, causing the vibrator 32 to start ultrasonic vibration. The pump 73 also starts operating, but because the inner space of the seal member 31 is an open space, in this state no suction force is applied to suck the detergent from the first storage container 231.
[2] Next, the operation mode of the head unit 3 is determined. The operation mode can be set to, for example, ultrasonic vibration mode, ultrasonic vibration/vibrator positive charging mode, ultrasonic vibration/vibrator negative charging mode, etc. This operation mode can be selected, for example, by changing the number of times the operation button 212 is pressed, the pressing time, etc.

[3] Then, the end of the seal member 31 of the head unit 3 is brought into contact with the desired skin surface. This forms a closed space between the seal member 31 and the skin surface. That is, the space inside the seal member 31 becomes a closed space (sealed space). Therefore, the supply tube 62 and the suction tube 72 communicate with each other through this closed space. As a result, by operation of the pump 73, the cleanser is sucked out of the first storage container 231, transported through the supply tube 62, and supplied to the skin surface from the supply port 611.
In this state, the vibrator 32 is also in contact with the skin surface, so that ultrasonic vibrations are applied to the skin surface.
Here, the frequency of the ultrasonic vibration is not particularly limited, but is preferably about 10 kHz to 100 kHz, and more preferably about 20 kHz to 90 kHz. The frequency of the ultrasonic vibration can be adjusted by devising the shape of the vibrating body 32.

The cleanser and ultrasonic vibrations can emulsify and remove sebum from the skin surface. If a peeling agent is used as the cleanser, keratin plugs clogged in the pores can be smoothly removed, and sebum and dirt (waste products) deep inside the pores can also be effectively removed. Furthermore, if the vibrator 32 is positively charged, it can promote the removal of dirt and other impurities from the pores.
The cleaning agent to which the sebum and dirt has been transferred is then sucked by the suction mechanism through the suction port 711 and collected in the second storage container 232 .
In this way, the cleaner 1 can easily remove not only sebum from the skin surface, but also blackheads, sebum, and dirt clogging the pores.
After the skin surface has been cleansed, the vibrator 32 may be negatively charged to introduce negative ions into the skin surface, thereby performing iontophoresis. If a beauty serum is applied to the skin surface at this time, the penetration effect of the beauty serum into the skin surface can be enhanced.

The portion of the upper case 21 below the partition wall 214 may be transparent (colorless transparent, colored transparent, or translucent), so that the state and color of the detergent collected in the second storage container 232 can be visually confirmed from outside the washer main body 2.
Furthermore, a light source (e.g., a white LED) may be disposed inside the upper case 21 near the partition wall 214. In this case, the state and color of the cleaning agent collected in the second storage container 232 can be more clearly seen from outside the cleaning device body 2.

The head unit 3 can also be configured as follows.
4A is a perspective view, FIG. 4B is a plan view, and FIG. 4C is a cross-sectional view showing another configuration of the head portion.
The head portion 3C shown in FIG. 4 has a sealing member 31 in the shape of a cylinder with a bottom (like a bottle cap), and a vibrating body 32 in the shape of a ring arranged outside the sealing member 31.
At the bottom of the sealing member 31, a through-hole 61 having a supply port 611 and a through-hole 71 having a suction port 711 are formed along the thickness direction.
This head portion 3C also provides the same functions and effects as the head portions 3A and 3B. Furthermore, like the relationship between head portion 3A and head portion 3B, it is possible to prepare a head portion of a different size from head portion 3C depending on the area (site) of the skin surface to be cleansed.

A mode lamp that lights up to indicate the selected operating mode may be provided on the front of the cleaner body 2. Preferably, the mode lamp is configured to be turned off when the cleaner 1 is powered off.
Furthermore, if the power supply unit 80 is composed of a secondary battery (rechargeable battery), a charging lamp may be provided on the front of the cleaner main body 2, which lights up when the secondary battery is in a charging state and turns off when charging is complete.
Furthermore, in this case, a charging terminal section is preferably provided at the lower part of the rear surface of the washer main body 2 .

The head unit 3 can also be configured as follows.
Fig. 5 is a cross-sectional view showing another configuration of the head portion, Fig. 6 is a perspective view (a) and a cross-sectional view (b) showing the configuration of the tip portion of the small diameter seal member.
The head unit 3 shown in Fig. 5 includes two (plural) different types of sealing members 31, 31a. In the configuration shown in Fig. 5, the vibrating body 32 is fixed to the ultrasonic vibrator 4. A cylindrical protrusion 320 is provided in the center of the vibrating body 32, and through-holes 61, 71 are formed in this protrusion 320. That is, the vibrating body 32 has the cylindrical protrusion 320, in whose end surface a supply port 611 and a suction port 711 open. The through-hole 61 is positioned approximately coincident with the central axis of the protrusion 320, and the through-hole 71 is positioned offset from the central axis of the protrusion 320.

The seal member 31 is annular and is detachably attached to the outer peripheral surface of the vibrating body 32. On the other hand, the small-diameter seal member 31a is annular and has a smaller diameter than the seal member 31, and is detachably attached to the outer peripheral surface of the protruding portion 320 (placed outside the protruding portion 320). In other words, the seal member 31 is configured so that one selected from the two seal members 31 and 31a is attached to the vibrating body 32 for use.
Furthermore, when the small diameter seal member 31a is attached to the outer circumferential surface of the protruding portion 320, the supply port 611 and the suction port 711 are exposed to the outside from the small diameter seal member 31a. In this state, the tip of the small diameter seal member 31a slightly protrudes from the vibrating body 32.

6, a brush structure 310 having a plurality of protrusions 310a may be provided at the tip of the small-diameter sealing member 31a. By providing such a brush structure 310, it is possible to increase the efficiency of removing keratin and keratin plugs.
The brush structure 310 has a through hole 311 formed substantially in line with its central axis, and a plurality of through holes 312 arranged in the circumferential direction centered on the through hole 311. When the small diameter seal member 31a is attached to the outer peripheral surface of the protruding portion 320, the through hole 311 communicates with the supply port 611 (through hole 61), and the plurality of through holes 312 communicate with the suction port 711 (through hole 71).

Furthermore, the head portion can also be configured as follows.
Fig. 7 is a perspective view showing another configuration of the head unit. Fig. 8 is a cross-sectional view showing the state in which the head unit of Fig. 7 is fixed to the device main body. In the following description, the upper side in Fig. 8 will also be referred to as "top" or "upper side", and the lower side will also be referred to as "bottom" or "lower side".
7 has a seal member 31b provided in the center thereof. This seal member 31b includes a cylindrical portion 311b and a partition wall portion 312b provided midway along the height of the cylindrical portion 311b.
The overall shape of the sealing member 31b is not limited to a cylindrical shape, but may be a rectangular tube shape, as long as it can form an airtight space (closed space) between the sealing member 31b and the skin surface.

8, the partition wall 312b has a plurality of protrusions 310b formed to protrude upward from its upper surface. The partition wall 312b also has a through hole 311 formed substantially in line with its central axis, and a pair of through holes 312 arranged opposite each other across the through hole 311. Therefore, it can be said that the upper portion of the seal member 31b has the same configuration as the brush structure 310 described above.
Furthermore, the partition wall 312b has a cylindrical fitting portion 313b that protrudes downward from the center of the lower surface of the partition wall 312b. The inner cavity of the fitting portion 313b and the through-hole 311 are in communication with each other.

An annular vibrating body 32b is provided at a predetermined interval on the outer periphery of the sealing member 31b. In this configuration example, the vibrating body 32b has a plurality of slits 321b along its circumferential direction. By providing these slits 321b, the amplitude of the vibrating body 32b can be increased.
The slits 321b may be unevenly arranged along the circumferential direction of the vibrating body 32b, but are preferably arranged at approximately equal intervals, which allows the amplitude of the vibrating body 32b to be uniform in the circumferential direction.
The number of slits 321b is not particularly limited, as it is set appropriately depending on the diameter of the vibrating body 32b, but is preferably 3 to 10, and more preferably 5 to 8.
The vibrating body 32b is not limited to the above configuration, and may be configured, for example, by arranging a plurality of arc-shaped plate members at predetermined intervals, with the spaces between adjacent plate members functioning as slits.

Furthermore, a plurality of vibrating bodies 32b may be arranged concentrically in two or three layers.
At the lower end of the vibrating body 32b, a disk-shaped support portion 33b protruding sideways (diametrically outward) is formed integrally with the vibrating body 32b.
In this configuration example, the ultrasonic vibrator 4 is fixed to the underside of the support part 33b. When the head part 30 is attached to the cleaning device body 2, the ultrasonic vibrator 4 is electrically connected to the power supply device 8.

In this configuration example, a mounting portion 26 is fixed to the ceiling of the upper case 21 so as to close the upper opening 213. Note that the upper case 21 is omitted from Fig. 8 .
With the head unit 30 attached to the attachment portion 26, the fixed cover 27 is attached to the upper case 21, thereby fixing the head unit 30 to the cleaner body 2. In this state, an O-ring 28 is disposed between the fixed cover 27 and the support portion 33b of the head unit 30, ensuring liquid-tightness inside the cleaner 1.

The mounting portion 26 is made of a disk-shaped member. A protruding portion 261 that protrudes upward is provided in the center of the mounting portion 26. A through-hole 61 is formed continuing from this protruding portion 261 to the mounting portion 26. The through-hole 61 opens at the upper end of the protruding portion 261, forming a supply port 611.
A through hole 71 is formed at a position radially outwardly shifted from the protruding portion 261 of the mounting portion 26 , and a suction port 711 is formed at the upper end opening of the through hole 71 .
Furthermore, an annular recess 262 recessed downward is formed on the outer periphery of the protrusion 261 (through hole 61) and the through hole 71 of the mounting portion 26.

With the head unit 30 attached to the attachment unit 26 , the protrusion 261 is inserted into and fitted into the fitting portion 313 b , and the ultrasonic vibrator 4 is housed in the recess 262 .
Therefore, in this configuration example, the detergent is supplied to the skin surface through the through hole 61 and supply port 611 formed in the center of the cleaner main body 2, and further through the through hole 311 formed in the center of the head part 30 (sealing member 31b).
On the other hand, the cleaning agent to which sebum and dirt have been transferred is sucked into the cleaning device main body 2 through the through hole 312 shifted radially outward from the center of the head part 30 (sealing member 31b), and further through the suction port 711 and through hole 71 shifted radially outward from the center of the cleaning device main body 2.

In this configuration example, the head unit 30 is fixed to the washer body 2 so as not to be detachable, but in such a configuration, the seal member 31b can be configured to be replaceable with a plurality of types of seal members having the same configuration or different configurations. As a result, when the seal member 31b is worn out, it can be replaced with a new seal member 31b, or the seal member 31b can be used according to the application.
In this case, the multiple sealing members 31b can be configured to differ in at least one of, for example, size (outer diameter), constituent material (flexibility), shape of the protrusions 310b, number of protrusions 310b, size (outer diameter) of the protrusions 310b and its rate of change along the longitudinal direction, number of through holes 311, and number of through holes 312.

The suction mechanism 7 may also be configured as follows.
FIG. 9 is a cross-sectional view showing another configuration of the suction mechanism.
In the following description, the left side in FIG. 9 will also be referred to as the "front" or "front", and the right side in FIG. 9 will also be referred to as the "back" or "rear".
9, the pump 73 is disposed at a location separated from the suction tube 72. Two tubes 74 and 76 are connected to the pump 73.
The tube 74 is provided to pass through the partition wall 214, and is configured so that its lower end is located inside the second storage container 232 when the lower case 22 is attached to the upper case 21. On the other hand, the tube 76 passes through the upper case 21 and communicates with the outside.

According to the above configuration, by bringing seal member 31 into contact with the skin surface, supply tube 62, suction tube 72, and tube 74 communicate with each other through a closed space (sealed space) defined by seal member 31 and the skin surface. By operating pump 73 in this state, the cleanser is supplied to the skin surface sequentially through supply tube 62, through-hole 61, and supply port 611 (i.e., from supply mechanism 6).
The cleanser supplied to the skin surface passes through the suction port 711 , the through-hole 71 and the suction tube 72 in this order, and is collected in the second storage container 232 .
With this configuration, the cleaning agent containing sebum and keratin plugs does not pass through the pump 73, so the number of maintenance tasks for the cleaner 1, such as cleaning the pump, can be reduced.

9, the end of the tube 74 opposite the pump 73 is covered with a filter 75. This filter 75 has the function of allowing gas to pass through but preventing liquid from passing through. By providing the filter 75, it is possible to effectively prevent the cleaning agent from leaking out of the second storage container 232.
The filter 75 may be omitted.

Second Embodiment
Next, a second embodiment of the cleaner of the present invention will be described.
The following description of the washer 1' of the second embodiment will focus on the differences from the washer 1 of the first embodiment, and a description of the same points will be omitted.
Fig. 10 is a perspective plan view showing a second embodiment of the cleaner of the present invention, and Fig. 11 is a perspective bottom view of the cleaner of the second embodiment.
In the following description, the front side of the paper in Fig. 10 will also be referred to as the "front" or "front," and the back side of the paper in Fig. 10 will also be referred to as the "back" or "back." Furthermore, the back side of the paper in Fig. 11 will also be referred to as the "front" or "front," and the front side of the paper in Fig. 11 will also be referred to as the "back" or "back."

The cleaner 1' of the second embodiment is similar to the cleaner 1 of the first embodiment except for its overall shape (particularly the shape of the vibrator 32') and omitting the suction mechanism 7.
As shown in FIG. 10, the front surface of the washer main body 2' is provided with operation buttons 211 and 212, as well as three mode lamps 24 and a charge lamp 25.
The vibrating body 32′ of the second embodiment is blade-shaped (flat plate-shaped). The thickness of the blade-shaped vibrating body 32′ is preferably about 0.2 mm or more and 0.8 mm or less, and more preferably about 0.4 mm or more and 0.6 mm or less.
The tip of this vibrator 32' is bent at an angle of between 10 and 20 degrees, and its tip surface 321 is configured as a curved concave surface to ensure a contact area with the skin. Furthermore, the tip corners of the vibrator 32' are rounded (R-shaped), which increases safety for the user.
As shown in FIG. 11, the hand electrode 5' is provided across the edge from the side surface of the washer main body 2' to the rear surface.

As shown in FIG. 11, the washer 1' of the second embodiment is configured so that a cartridge-type first storage container 231' can be detachably attached to the rear surface of the washer main body 2'.
The supply mechanism 6 includes a supply tube 62 made of, for example, metal or hard resin, which extends from the washer main body 2 to the head unit 3'. A supply port 611 at one end of the supply tube 62 opens near the bent portion of the vibrator 32'. The other end of the supply tube 62 is provided with a puncture needle (such as a bottle needle) 621 for piercing the stopper provided in the first storage container 231'.
The first storage container 231′ in the second embodiment is made of, for example, a flexible material. In this case, by pressing the container itself with a finger or the like, the cleanser can be supplied from the supply port 611 to the surface of the vibrator 32′ and the skin surface.

Furthermore, according to the second embodiment having such a configuration, a gel-like cleanser is preferably used in order to prevent or suppress premature scattering of the cleanser from the target area on the skin surface.
The washer 1' of the second embodiment as described above also provides the same functions and effects as the washer 1 of the first embodiment.
Furthermore, when a protease is used in a cleaning agent, it is preferable to keep the protease separated from the cleaning agent (e.g., water) until immediately before use in order to prevent alteration and deterioration of the protease. The cartridge-type first storage container 231' can be configured such that its internal space is divided by an easily breakable partition, with the protease stored in one space and the cleaning agent stored in the other space. The partition can be configured to break, for example, when the first storage container 231' (stopper) is connected to the supply tube 62 (puncture needle).

According to the configuration described above, by combining vibrations on the skin surface with a cleanser, it is possible to provide a cleanser that can easily remove not only sebum from the skin surface but also keratin plugs clogged in pores. Moreover, since the cleanser does not use forced suction to remove keratin plugs, damage to the skin surface can be prevented or reduced. Furthermore, since the user can use the cleanser by switching between cleaning water and peeling agent depending on the condition of their own skin surface, it is easier to prevent damage to the skin surface.
Furthermore, any of the configurations shown in the first and second embodiments may be combined with each other.
