FIG. 2B is a side view illustrating the soap solution supply device according to the embodiment.
FIG. 3 is a cross-sectional view illustrating the soap solution supply device according to the embodiment.
The soap solution supply device 100 includes a mounting pipe 12, a soap solution tank 14, and a main body portion 15.

As shown in FIG. 3, the mounting tube 12 penetrates the counter 200. The mounting tube 12 is fixed to the counter 200 by a nut 22 below the counter 200. A washer and packing 21 are provided between the nut 22 and the counter 200.

The soap solution tank 14 is provided below the counter 200 and is connected to the mounting pipe 12 by the joint 23. Packing 23a, 23b and the like are appropriately provided between the joint 23 and the mounting pipe 12 and between the joint 23 and the soap solution tank 14. The soap solution is stored inside the soap solution tank 14.

At least a part of the main body 15 is provided above the counter 200. The main body 15 is detachably connected to the mounting tube 12.

A hose portion 25 extending to the inside of the soap solution tank 14 is connected to the lower end of the main body portion 15. The hose portion 25 has a hose 25c and a filter 25a connected to the tip of the hose 25c via a joint 25b.

4 (a) and 4 (b) are exploded views illustrating the soap solution supply device according to the embodiment.
FIG. 4A shows a state in which the mounting pipe 12 and the main body 15 are disassembled, and FIG. 4B shows a cross section of FIG. 4A.
The main body 15 includes a handle 40, a resin member 42, a foaming member 44 (filter), an outer member 46, a packing 48, a cap 26, a pump unit 30, a cover member 28, and a C ring 29. (Retaining member) and.

As shown in FIG. 4B, the pump unit 30 includes a liquid pump 31 and an air pump 32. The liquid pump 31 takes in the soap liquid in the soap liquid tank 14 from below via the hose portion 25, and sends the taken-in soap liquid upward. The air pump 32 takes in air and sends the taken in air upward. As a result, the pump unit 30 sends a mixture (mixture) of the soap solution and air to the upper handle portion 40. The liquid pump 31 and the air pump 32 (piston and cylinder described later) are each made of resin. For example, polypropylene (PP) can be used for each of the material of the liquid pump 31 and the material of the air pump 32.

The cover member 28 has a tubular shape and covers at least a part of the pump unit 30. For example, as shown in FIG. 4B, the cover member 28 is attached so as to cover the lower part of the pump unit 30. A cap 26 is attached to the upper part of the pump unit 30.

The cover member 28 and the cap 26 are made of resin. For example, polyphenylene sulfide (PPS) can be used as the material of the cover member 28.

The outer member 46 has a tubular shape and covers at least a part of the cover member 28 and the pump unit 30 (see FIGS. 3 and 4 (b)). In other words, at least a part of the pump unit 30 is housed inside the outer member 46. At least the surface of the outer member 46 is made of metal. For example, the outer member 46 is made of metal, but may be a non-metal such as plastic plated with metal. The metal used for the outer member 46 is, for example, an alloy containing copper (copper-based alloy).

The C ring 29 is attached between the outer circumference of the cover member 28 and the inner circumference of the outer shell member 46 (see FIG. 3). As a result, the pump unit 30 covered with the cover member 28 is prevented from coming off from the outer member 46 by the C ring 29. By removing the C ring 29, the pump unit 30 covered with the cover member 28 can be pulled out from the outer member 46. That is, the pump unit 30 is removable from the outer member 46.

The handle portion 40 is detachably connected to the pump unit 30. The unevenness 40a provided on the lower portion of the handle portion 40 (for example, a groove or a snap fit) and the unevenness 30a provided on the upper portion of the pump unit 30 directly or indirectly engage with each other. The handle portion 40 can be removed by pulling the handle portion 40 upward while rotating the handle portion 40. Similar to the outer member 46, at least the surface of the handle portion 40 is made of metal.

When the handle portion 40 is pushed downward, it slides with respect to the outer member 46 and drives the pump unit 30. As a result, the pump unit 30 sends the mixture of the soap solution and the air upward. Further, the handle portion 40 has a nozzle 41 extending laterally from the upper portion of the handle portion 40.

The resin member 42 is fitted inside the handle portion 40 from below the handle portion 40. When the handle portion 40 is pushed in, the resin member 42 prevents the handle portion 40 and the outer member 46 from directly colliding with each other, and functions as a guide member for smooth sliding.

The foaming member 44 is provided at the connection portion between the pump unit 30 and the handle portion 40. The foaming member 44 has a plurality of holes (for example, a net). The mixture of soap solution and air sent from the pump unit 30 is guided into the handle portion 40 through the foaming member 44. The mixture is converted into fine bubbles by passing through the foaming member 44. After that, the mixture (foam) is discharged from the discharge port 41e of the nozzle 41 through the handle portion 40 and the nozzle 41.

The main body 15 is detachably connected to the mounting tube 12. Specifically, as shown in FIG. 4A, the lower part of the pump unit 30 is provided with an unevenness 30b (for example, a snap fit), and as shown in FIG. 4B, the upper part of the mounting pipe 12 is provided. The unevenness 12b is provided on the inside of the. The main body portion 15 is attached to the mounting pipe 12 by engaging the unevenness 30b and the unevenness 12b. The main body 15 can be removed from the mounting tube 12 by pulling the main body 15 upward.

After removing the main body 15, the soap solution tank 14 is replenished with soap solution from the opening 12a of the mounting tube 12 located above the counter 200 via the mounting tube 12.

FIG. 5 is a cross-sectional view illustrating the soap solution supply device according to the embodiment.
FIG. 5 is an enlarged view of a part of the vicinity of the pump unit 30. The pump unit 30 has a piston 33 and a cylinder 34. The above-mentioned liquid pump 31 and air pump 32 are formed by the piston 33 and the cylinder 34.

The cylinder 34 is supported by the cover member 28.
The piston 33 has an air piston 33a and a liquid piston 33b. The air piston 33a and the liquid piston 33b can each slide up and down with respect to the cylinder 34. The liquid piston 33b and the cylinder 34 form a liquid chamber RL for storing the soap liquid inside. The air piston 33a and the cylinder 34 form an air chamber RA that stores air inside. Further, a mixing chamber RM is formed above the liquid chamber RL and the air chamber RA.

A ball 39 (check valve) is provided at the lower end of the liquid chamber RL. The liquid chamber RL is connected to the soap liquid tank 14 via the attachment pipe 12, but when the soap liquid supply device 100 is on standby, the lower end of the liquid chamber RL is closed by the balls 39.

An inner rod 35, a plug 37, and a spring 38 are provided inside the liquid chamber RL. The plug 37 holds the inner rod 35 and the spring 38. The spring 38 urges the piston 33 upward by its elastic force. The upper part of the inner rod 35 extends to the mixing chamber RM and becomes the mixing chamber check valve 36c.

When the user pushes the handle portion 40 downward, the force (operating force) for pushing the handle portion 40 is transmitted to the piston 33. As a result, the air piston 33a and the liquid piston 33b move downward. Then, since the volume of the liquid chamber RL is reduced, the soap solution in the liquid chamber RL flows into the mixing chamber RM through the mixing chamber check valve 36c. At this time, the lower end of the liquid chamber RL is in a state of being closed by the ball 39. Also, the spring 38 is contracted.

At the same time, since the volume of the air chamber RA is reduced, the air in the air chamber RA flows into the mixing chamber RM through the check valve 36a and the mixing chamber check valve 36c provided in the air piston 33a. At this time, the check valve 36b provided on the air piston 33a is closed.

In the mixing chamber RM, air and soap solution are mixed. Then, the mixture is discharged from the small hole P provided in the upper part of the mixing chamber RM to the foaming member 44 and the handle portion 40. As a result, soap bubbles are discharged from the nozzle 41.

After that, when the user releases the handle portion 40, the air piston 33a and the liquid piston 33b move upward due to the elastic force of the contracted spring 38. Then, the volume of the liquid chamber RL increases, and a negative pressure is generated in the liquid chamber RL. At this time, the mixing chamber check valve 36c is closed and the ball 39 is raised. As a result, the soap liquid is supplied into the liquid chamber RL from the lower soap liquid tank 14, and the inside of the liquid chamber RL is filled with the soap liquid.

At the same time, the volume of the air chamber RA increases, and a negative pressure is generated in the air chamber RA. At this time, the check valve 36a is closed and the check valve 36b is opened. As a result, air is supplied to the air chamber RA from the outside. As a result, the soap solution supply device 100 returns to the standby state.

The structure and operation of the soap solution supply device 100 according to the embodiment have been described above.
By using resin as the material of the pump unit 30, for example, the manufacturing cost can be suppressed. On the other hand, when resin is used as the material, the durability of the pump unit tends to be lower than when metal is used as the material. Therefore, it is desired to improve maintainability when the pump unit breaks down. In particular, if the soap solution supply device 100 is for public use, it may easily break down.

Therefore, in the embodiment, as described with respect to FIGS. 3, 4 (a) and 4 (b), the pump unit 30 is detachable from the outer member 46. As a result, even if the pump unit 30 fails, only the pump unit 30 can be replaced. Therefore, maintainability can be improved.

A specific example of attaching / detaching the pump unit 30 will be described.
FIG. 6 is a perspective view illustrating an outer shell member, a cover member, and a pump unit.
For convenience of explanation, a part of the outer member 46 is omitted and the cross section is displayed.
FIG. 7 is a perspective view illustrating the C ring.

As described above, the cover member 28 covers at least a part of the outer circumference of the pump unit 30. As shown in FIG. 6, the cover member 28 has an upper portion 28a and a lower portion 28b. The diameter of the upper 28a is larger than the diameter of the lower 28b.

A step portion 47 is provided on the inner circumference (inner wall) of the outer shell member 46 that covers the cover member 28. The step portion 47 is formed by a first portion 47a having a large diameter and a second portion 47b having a small diameter.

The C ring 29 is attached between the lower portion 28b of the cover member 28 and the first portion 47a of the step portion 47. As shown in FIG. 7, the C ring 29 has two handle portions 29a arranged on the circumference of the ring. In this example, the handle portion 29a is a hole provided at both ends of a substantially C-shaped ring.

For example, the outer diameter of the C ring 29 is smaller than the diameter of the first portion 47a of the outer member 46 and larger than the diameter of the second portion 47b. As a result, the C ring 29 is supported by the step portion 47. The inner diameter of the C ring 29 is smaller than the diameter of the upper portion 28a of the cover member 28 and larger than the diameter of the lower portion 28b. As a result, the cover member 28 and the pump unit 30 are supported by the C ring 29. As described above, the pump unit 30 and the cover member 28 are supported by the outer member 46 via the C ring 29 and are prevented from coming off.

FIG. 8 is a plan view illustrating an outer shell member, a cover member, and a pump unit.
FIG. 8 corresponds to a state in which the main body 15 is viewed from below. When removing the pump unit 30 from the outer member 46, first, the main body 15 is removed from the mounting pipe 12. Then, in the state shown in FIG. 8, the C ring 29 is picked. Specifically, a force is applied to the handle portion 29a so that the diameter of the C ring 29 is reduced by passing, for example, a tweezers-shaped tool or the like through the two holes of the handle portion 29a. For example, resin or metal is used as the material of the C ring 29, and the diameter of the C ring 29 can be reduced according to the applied force. As a result, the cover member 28 and the pump unit 30 can be removed from the outer member 46.

As described above, according to the embodiment, the pump unit 30 can be prevented from coming off by using the C ring having the handle portion, and the diameter of the C ring 29 can be reduced to easily remove the pump unit 30. Can be done.

Further, since the pump unit 30 is attached to the outer shell member 46 via the cover member 28, it is possible to prevent the pump unit from being damaged when the main body 15 and the pump unit 30 are attached and detached.

When PP having high chemical resistance is used for the pump unit 30 and an alloy containing copper is used for the outer member 46, the PP tends to deteriorate due to contact with copper. On the other hand, in the embodiment, the pump unit 30 is separated from the outer member 46 and is not in contact with the outer member 46. Specifically, the cover member 28 shields the pump unit 30 from the outer member 46. As a result, deterioration of the pump unit 30 can be suppressed. That is, by providing the cover member 28, it is possible to both protect the pump unit 30 at the time of attachment / detachment and suppress deterioration of PP due to copper.

9 (a) and 9 (b) are cross-sectional views illustrating the soap solution supply device according to the embodiment.
9 (a) is a cross-sectional view of the soap solution supply device 100 above the counter 200, and FIG. 9 (b) is a cross-sectional view of the mounting pipe 12 attached to the counter 200.

As shown in FIG. 9A, a flange portion 34f is provided on the upper portion (upper end) of the cylinder 34 of the pump unit 30. The flange portion 34f is placed on the upper end 28e of the cover member 28 and is in contact with the upper end 28e. As a result, the pump unit 30 is supported by the cover member 28 at the flange portion 34f. For example, the cylinder 34 is suspended from the upper end 28e of the cover member 28 by the flange portion 34f. The pump unit 30 is attached to the outer member 46 via the cover member 28 and the C ring 29.

As a result, even if the handle portion 40 is pushed in and the operating force is applied to the piston 33 from above, the operating force is not directly transmitted to the bottom portion of the pump unit 30 (the bottom portion of the cylinder 34). Therefore, damage to the pump unit 30 can be suppressed.

The soap solution supply device 100 further includes an anti-theft wire 50 (an anti-theft member). The anti-theft wire 50 prevents the main body from being stolen when the main body 15 is attached or detached. As shown in FIG. 9A, one end of the anti-theft wire 50 is attached to the cover member 28. As shown in FIG. 9B, the other end of the anti-theft wire 50 is detachably locked to the inside of the mounting pipe 12 or the soap solution tank 14.

By attaching the anti-theft wire 50 to the cover member 28 in this way, it is not necessary to directly attach the wire to the pump unit 30, and damage to the pump unit 30 can be suppressed.
