In the symbols (i), (ii) and (i), (a),
It is quoted with (b). [Example of the invention] (Water pump)   The type and system of the electric water pump used in the present invention are basically
It does not matter, but it is available at the time of filing the present application.
As a simple shaped water pump, pumping kerosene for home use
There is a dry battery pump that is used for
Move. The ones on the market operate at a rated voltage of 3V, and
0cm^ThreePumping capacity of about / second. In this specification,
Use of dry cell pumps and pumps that operate with the same mechanism
The explanation proceeds assuming that Water pump shown in Fig. 24
Is the configuration of this dry battery pump. Operates on DC
A water blade 23 is attached to the motor 22. Water feather
23 is a flat blade having a surface parallel to the rotation axis.
At the center of rotation of the water blade from the water inlet 24 smaller than the turning radius
Receive water supply and supply water by centrifugal force of rotation
The water is pushed to the surrounding area and the water is pumped up. In FIG.
The water impeller 23 is attached adjacent to the
Motor and make the shaft connecting the
The position of the key may be raised upward. Location of water blade 23
Must be near the water inlet 24 due to the principle of operation of the dry cell pump.
I have to. Puddle3Although there is no particular limitation on the capacity of
Usually 50-300cm^ThreeAnd therefore, based on the pumping capacity described above,
It can be filled with water for at most 2-3 seconds. Electric
Usually, two batteries are used in series, but one battery
It can be driven at 1.5V. Disconnect the power cord
If so, it is possible to rectify and use the AC power supply. (Example according to form and structure)   1 and 2 described above are the most basic ones.
It is a form. Combined shape based on cylindrical shape
However, in addition to the convenience of production,
To facilitate the determination of whether or not to use it. That is, normal city
Many vases on sale have a circular cross section,
The mouth shape is also circular. The device has a column-based configuration
If you know the depth of the vase and the diameter of the mouth, you can use the vase
It is possible to easily determine whether or not it is possible to put in. Second
In the figure, the device shows almost the entire space inside the vase,
If there is enough space in the bottle, the flowers will remain with the equipment installed.
It is also possible to live. Somewhat difficult to live, but the water in the device
Reservoir3It is not impossible to insert a flower into the plant. Or
Change the shape of the puddle1Leave the neighborhood of
May be deepened to make it easier to insert flowers.   The cross-sectional view shown in FIG.
Go ahead and put together so that the entire outer shape is almost cylindrical
This is an example. Hollow cylinder open at both ends
The same water pump as in Fig. 24Incorporate
The water pumping pipe 21 is connected to one of the circumferences of the outer cylindrical wall 33 of the hollow cylinder.
Installed in contact with the side, occupied by a pumping tube in a hollow cylinder
A partition is provided in one place of the remaining space and the bottom 50
And the upper part is a puddle3And 1 dripping port on the bottom 501
Is provided, from which water drops fall down
You. The outer container has the functions of a support, a side wall of a water reservoir, and a resonance cylinder.
One. The ventilation port 30 provided with one space of the outer container wall 33
Suppress changes in atmospheric pressure inside the container and transmit the generated water noise to the outside.
In order to obtain Unlike the example of FIG. 2, the water level sensor 25
The battery 31 is separated from the control circuit 32 and
Is placed next to the motor 22 in the water of
(Ii) control method without using the water level sensor
Is exemplified. These configurations reduce the overall size of the device.
It contributes to making it as small as possible. Battery and mode
The unit is waterproof and integrated as a model
Underwater motors are commercially available. Blade of the submersible motor
Is a so-called propulsion screw that serves as a pumping device.
You can not get enough effect even if you use it,
Change the shape and take out the control lead wire.
It has basically the same configuration as the pond motor.   The size of the device is not limited by the configuration of the invention
However, there are some restrictions in actual production. Equipment shape
When the shape is like a cylinder, even the smallest
The height is the drop distance of the water drop, the depth of the water pool, the drop hit by the water drop
Considering the depth of the water system that provides the sewage surface, at least
15 to 20 cm is required, the diameter is the diameter of the pumping pipe and the dropping port
About 3 cm is required. Impossible in design considering practicality
Standard size without height, height 20-30cm, diameter 5-10cm
It is. Therefore, the device according to the invention can be used in a vase.
If used, the vase side should be of these dimensions
If it is not large enough to put the
It cannot be a "vase that emits a water sound" that shows fruit.   For the relatively large vases in the sectional views of FIGS.
Here are some examples that can be used. If the vase is big, water
To increase the dropping distance of the drops and the generated water noise
Can be. In Fig. 4, the drip port1Water puddle3But hanging equipment
Hanged on the edge of the vase mouth by 35
35 plays the role of support. The hanging tool 35 is removable
There may be. Water pump at the bottom of the vase4More pumping
This takes place through a flexible pumping tube 34, where the vase depth is
The same device can be installed even if it is slightly different. Use resonance tube
Although not done, the space inside the vase also exhibits some resonance effects.
I do. FIG. 5 shows a case where the resonance cylinder 26 has a function of a support.
Therefore, as in the example of FIG.
I have. Resonance tube 26 can be detachable or detachable
A short hollow pipe into a long hollow cylinder
The height of the device can be changed if necessary
Can be. No special need for the resonance effect of the resonance tube 26
In some cases, a hollow cylinder with lattice or stitched walls
May be. Even in this case, when flowers are inserted in the vase
In addition, a machine that prevents the shoots from obstructing the drip path of water droplets
Noh remains.   The above is an example of using the device in a vase.
However, it can also be used in a basin or the like. This place
Although the appearance of the combined device is a problem,
Consider the inn or cover the area with flowers and see from the outside
Care must be taken to ensure that (Drip port)   The sound of the generated water is the volume, shape and impact water
Due to the falling distance to the surface,
You. Among them, the effect of the amount and shape of water droplets is particularly large.
No. The drip port is a part that is set up to form this water droplet.
However, as a general trend, the amount of water dropped
The more the sound, the better the sound and the deeper the sound. Only
However, there is a physical limit to forming large amounts of water droplets.
In addition to that, if the amount is too large,
In some cases, the sound becomes quieter. standard
Typical volume is 0.1-0.5cm^ThreeIt is about. Fall distance is about 15cm
If the amount is 0.2cm^ThreeIf it is about
Listen to every corner of the room in a quiet environment in a living space
It emits enough water noise. 0.2-0.3cm^ThreeWater droplets form
This is relatively simple. 0.4cm^ThreeWhen it is over
The sound of the sound is not often overlooked, but the structure of the drip port
Requires special considerations as described below. By the drip port
Is 1cm^ThreeWhere water droplets can be formed in the amount of water
0.5cm^ThreeIf you fall beyond, you may catch a tail when falling
Many. However, changing other elements of the water noise
In this case also generate a sufficiently interesting sound
Is possible. Naturally increasing the fall distance is effective
However, the size of the vase is limited. Otherwise
For example, the lower end of the resonance cylinder 26 shown in FIG.
Although it is above, lower the position of the resonance tube further down, and
Is soaked in water, only the resonance condition of the resonance cylinder
Instead, the condition of the water surface being hit changes, and the sound of the generated water
The size and sound quality also change. Good effect when tailing
give.   The formation of water droplets depends on the nature of the surface tension of water, and is basically
If a relatively small outlet with a limited water flow rate is configured,
Formed. The simplest structure has a fine mouth at the bottom of the pool
It is just an empty space. 0.2-0.3cm^ThreeMinutes to the extent
With the amount of water droplets, this can be sufficiently formed. In FIG.
In the example, the fine port 51 is opened in the water bottom 50,
Some depression around the mouth, resulting in larger droplets
Like that. The position of the dropper is not necessarily at the bottom of the pool.
It is not necessary to guide it in an appropriate waterway and it may be installed elsewhere
However, it is better to install it directly at the bottom of the pool to spread the entire device.
It is also preferable from the point of holding down, so attach it to the bottom of the pool below.
The explanation proceeds assuming that In Figure 7, inside the hollow cylinder
The hollow tube 60 is separated from the water bottom 50 by the set screw 56 and the nut 54.
It has a suspended structure. Water for screws and screws
After passing through the hole, it reaches the inside of the hollow thin tube 60 and its tip forms a water droplet
Part 52. Spring washer for washer 55
It is possible to leave a certain gap like an internal tooth washer
The water flow is maintained by using the water bottom 50 and the hollow thin tube 60.
Use an O-ring 58 or packing to remove water
To prevent leakage. Several types of hollows that can be attached and detached
In addition to being able to prepare and replace the thin tubes as appropriate,
Adjust the amount of water flow by adjusting the set screw and nut
To determine the optimal conditions for the formation of water droplets,
Time intervals can be varied.   The formation of water droplets depends on the surface tension of the water.
To form a droplet, increase the diameter of the droplet and
Keep it in the dropper, not drop, until the drop grows big
Power, which is mainly used for the water of the material of the drip port.
Depending on the wettability. In order to increase the power, the formation
Area of contact between the falling water droplet and the material constituting the drip port
It is necessary to measure expansion. Small water flow into hollow cylinder
This condition can be met to some extent by leading
Relatively large water droplets can be formed. At this time
Importantly, the water inside the hollow cylinder
The formation of water droplets over the entire circumference of the inner wall of the cylinder
You. The flow of water is uneven and only part of the inner wall is in contact with water
Large water droplets are not expected when falling
No. Generally, it is formed if the inner diameter of the hollow cylinder is large
Water droplets also grow, but after a certain amount of water
It does not cover the entire circumference of the wall. Full circumference while maintaining a large inner diameter
Creating a condition that can wet
This is a condition for forming a large water droplet at the lower mouth. Seventh
In the example in the figure, the purpose is to help water spread all around the hollow capillary 60
, The porous substance 53 is inserted. With thread 57
It is experimentally confirmed that both contribute to this purpose. water
A corrugated foam fitting used for a faucet is inserted into a hollow thin tube.
Installation is also effective. Urethane pho
A so-called sponge such as a sponge may be used. Amount and shape of porous material
This also affects the size and shape of the formed water droplet. Hollow
As the material of the thin tube 60, glass having good wettability to water,
Metal is standard, but when plastic is used
Large enough to have a porous material or threaded structure
It is possible to form water droplets. Usually available
The inner diameter of the hollow tubule is about 1.0-1.5 cm, but 1.0-1.2
Up to about cm, wet the entire circumference with a simple hollow cylinder structure
In this condition, water droplets can be formed.
The amount is about 0.2-0.3cm^ThreeIt is. To form even larger water droplets
To increase the inner diameter, use porous materials, screws
Take measures such as carving mountains.   8 and 9 are basically hollow cylinders as in FIG.
In FIG. 8, the tip of the hollow thin tube 60 is shown in FIG.
The diameter of the part is narrowed, so that water contacts with the material of the drip port
In order to increase the area, a flat plate on a suspended disk
A disk end 61 is provided. In this example,
The introduction of water into the pipe 60 is performed by the fine port 51.
You. In FIG. 9, as the diameter of the hollow thin tube 60 goes to the tip,
And spread, and have a trumpet shape as a whole. Circle
The purpose is the same even in the shape of a pan or a bowl
is there. Screw threads 57 are engraved on both the bottom 50 and the drip port side.
The drip port is removable. The introduction of water
This is performed through the porous substance 53 at the base of the trumpet. Seventh
Unlike the example in the figure, the porous material mainly controls the flow rate of water.
It is used for the purpose. Made of materials such as urethane foam
If the eyes are rough and the amount of running water is too much,
Use fine material. Water is from the trumpet-shaped root to the pipe wall
Descends while spreading along the inner wall of the hollow thin tube 60 even at the tip
All around.   Water droplet formation starts even if the structure and size of the dropper are the same
The size and shape of water droplets formed depending on the initial state
In some cases. In particular, air may remain inside the drip port
In this case, water does not reach the entire inner wall of the hollow
This often hinders the formation of water droplets. Such as a water tap
Water can be dropped by reducing the flow rate of water.
In the case of a road, open the tap once, pour water, and tap faucet
Air in the pump can be removed,
Are advantageous. In the case of the drip port according to the present invention,
Similarly, install a stopper, etc. to allow a large amount of water to flow temporarily.
Or immerse it in water beforehand.
It is better to remove the mind. From this perspective
Et al. Use a porous material as shown in FIG.
It is effective in forming stable water droplets that are less likely to remain inside.
High utility.   The loudness, timbre, and sound quality of the water sound are
This depends greatly on the size and shape, but this
Many depend on the size and structure of the drip port to be formed.
The range of change is quite large. With a design with a removable dropper
If so, the type of water sound may be selectable. Each falling water drop
The time interval between the water droplet and the water droplet depends on the surface tension and water
As a result of physical action such as wettability of the
Is almost constant depending on the type and condition of
Because it is done at a fixed period, it is monotonous depending on how you listen
May give you an unnatural impression.
If two or more drip ports are provided in the device, each drip port
These cycles cause water drops to be dropped and make a water noise.
Mixing sounds and monotony is alleviated. This time again
The target spacing is also affected by the water level in the basin. (control method)   First, an example of method (i) using a water level sensor
State. The simplest configuration is the ON-OFF type sensor switch.
When the switch is attached to the pool and drops to a certain water level
The water pump is driven to keep the water level constant (i)
This is the method shown in FIG. Independently controls the power of the water pump
Floats using floats can be controlled
There is a switch to control in combination with an appropriate control circuit
Level sensors using electrodes, piezoresistors
Pressure sensor, light emitting diode and light receiving
A reflective photointerrupter consisting of elements can be used.
You. Both are well-known control methods. Direct power ON-OF
For switches that can control F, a special control circuit
No need for sensor switch, dry cell, water pump
Operation can be confirmed simply by connecting the three
In fact, the configuration is simple and battery consumption is low, but
The latter case is considered from the viewpoint of miniaturization and reduction of manufacturing cost.
It can be useful. Rotated as a float switch in Fig. 10
Shown below is an example of combining a micro switch with a float.
You. Float at the tip of arm 72 linked with micro switch 70
There is a child 71 to transmit the buoyancy to the arm, and to the center of rotation 73
Apply counterclockwise torque. Built-in micro switch
The spring is working and always applies clockwise torque to the arm.
If no external force is applied, rotate until it swings clockwise
Switch is in the ON position. water
In the state where the water level of the reservoir is high and the buoyancy by the float 71 is working
The switch is off and the water level is below a certain position.
Switch turns on and the water pump is driven.
You. Water is pumped up by the water pump and the water level in the basin 15 rises.
Switch off when ascending. ON-OFF type switch
Switch switching is performed strictly at a certain position
This does not mean that once the switch is switched,
Switching position until the next switching operation is possible
The play is usually called a dead zone. This
The switch ON-OFF is repeated across the dead zone of
The operation and standby state of the water pump are repeated at relatively short intervals.
Will be returned. As a result, the water level of the sump corresponds to the dead zone.
It is kept at a substantially constant position leaving only the fluctuation range. Water bottom
Since the water pressure at 50 is constant, the water
Supply conditions are kept constant, and the time interval between
But the sound when the water pump is running
Also, there is no point in giving capacity to the pool. Commercially available
The rotary operation type micro switch has a switching operation.
The torque required for
You. For example, use a device that operates at 10 g
Use a length of 2cm and float like Styrofoam
The weight can be almost ignored, so the volume of the float is 5 cm^Three
I just need. A cylindrical shape with a diameter of 2 cm and a height of 2 cm is sufficient,
Fully integrated into the usual size of the device according to the invention
It is possible.   On the other hand, using the ON-OFF switch,
The water pump is started when it is almost empty and is full.
After that, the system is stopped and enters the standby state.
is there. If a switch with a large dead zone is used in the above configuration,
Performs a similar operation, but more reliably performs this operation.
For example, a time-recovery timer is used for the sensor switch.
There are some combinations. The various sensor switches described above
Switches are available as well. Sensor switch is conducting once
Then, the water pump is driven via the timer circuit and the control circuit.
Activated and the sensor switch is still open for a certain amount of time
The water pump continues to be driven. Lifting water pump
Determine the appropriate time width of the timer from the water capacity and the capacity of the pool
I do. The duration of the timer need not be strict
No. Simple and inexpensive configuration of such a timer circuit
As an example, it is known as a timer IC in Figure 11.

The configuration that performs the same action as when the
You. In the figure, the power supply of the water pump is directly
One of the float switches that can be opened and closed is shown
However, it is not limited to this, and opens and closes the power supply via a control circuit
Even if it is an ON-OFF type water level sensor, the same
The same function can be achieved by the configuration. Features of this configuration
Is to simply set up a float switch in the pool

Then, the water level of the water reservoir main tank 49 starts to rise. However, this stage
The water supply to the float chamber 40 on the floor takes place through the small holes 44
However, the flow volume of the small hole 44 is extremely small, so the float chamber
The water level inside does not rise easily. Water level condition shown in Fig. 13
Indicates the state during operation of the water pump at this time.
It is. Float switch is compatible with dead zone
And the position of the magnetic float 41 rises slightly.
Switch does not switch over,
Pumping by the water pump is continued. Reservoir main tank 49
Water level rises gradually, but above the float chamber partition wall 45
The edge is slightly lower than the top 48 of the basin wall, and the difference is
The upper space 47 of the float chamber is
Before the water overflows the sump wall top 48 and overflows the sump,
Flows into the float chamber through the upper gap 47 of the float chamber.
You. As a result, the position of the magnetic float 41 rises and the switch
Is turned off and the water pump stops. Since then
As the process progresses, the water gradually floats through the small holes 44.
40, the water drop falls through the drip port,
Float room 40 and main water tank are used when it is almost empty again
49 water levels are equal, and the water level drops to a certain position.
The same will be repeated again.   Next, the timer circuit (ii) that does not use the water level sensor
An example of the method used will be described. The above-mentioned limited return type tie
As in the case of Ma, time accuracy is not strongly required.
The standard timer configuration uses an oscillator circuit and a frequency divider
However, is it a viewpoint aimed at a cheap and simple circuit configuration?
Shows an example using a timer IC as in the case of the time-recovery type.
You. FIG. 14 shows the same operating characteristics as NE555 described above.
This is a well-known control circuit using one ICM7555. ICM7555
Has low power consumption and operates on 3V power supply with 2 batteries
Can be This is called an astable multivibrator
And make it work. Pin 3 output voltage is either zero or power
It takes one of the states equal to the power supply Vs.
By properly controlling the separation, the corresponding water port
It controls the operation and standby of the pump. Time constant control capacity 82 and 2
The time constant control resistors 81 are connected to the positions shown in the figure. Time constant system
Input and output voltage of pin 6 and pin 2 by charging / discharging control capacity 82
The point of operation by changing
Is the same. Fig. 15 shows the horizontal axis for the purpose of showing the operation.
The voltage Ec across the time constant control capacitor 82 with a common time axis
And the change in the output voltage Vout of the third pin. Vout
When zero, the water pump stops, and when Vout takes the value of Vs
The water pump is in operation. Fig. 15 shows 7 pins and 1 pin.
That the time constant control capacitor 82 is in a discharged state.
It starts from the beginning. Discharge is performed by two time constant control resistors 81
R between pin 7 and pin 2_TwoIt is performed through. Release
When Ec drops below 1/3 of the power supply Vs
To open between pin 7 and pin 1 to start charging
You. When the time constant control capacitor 81 is in a charged state, Vout is
Take the value of the power supply voltage Vs. During charging, the time constant control
The quantity 82 is connected to the power supply 83 via two time constant control resistors 81
But R due to the presence of diode 93_TwoIs shorted,
R₁Will only be charged via. As charging progresses
If Ec exceeds 2/3 of Vs, it will be inverted and pins 7 and 1 will lead.
Throughout Vout becomes zero. When the potential of pin 7 drops
As a result, the time-constant control capacity 82 enters a discharge
Repeat the work. Diode 93 reverses direction when discharging
Does not conduct, so the discharge is R_TwoVia pin 7, pin 1
It is. 3 pin output voltage goes to switch transistor 84
The motor is controlled by the operation of this transistor.
Activate the relay 94 to control the water pump motor 22
You. Control relays rated at 3V or 1.5V are available
You. A commercially available relay with a rated voltage of 3 V operates at about 100 mA.
There are many things to make, so switch transistor 84
It has enough capacity to control this amount of current and
Voltage drop due to collector current
Those with low flow are desirable. For example, 2SC735, 2SC1053, 2
SC1996 and others. Suitable micro relay with small operating current
If there is a switch, remove switch transistor 84 and
Circuit configuration in which the relay control relay 94 is directly connected to pin 3 is also possible.
Noh. However, unlike the case of NE555, the output power
Since the current cannot be so large, the motor 22
Circuit configuration to connect to the pins is difficult.   Water pump corresponding to the time when the value of Vout is the power supply voltage Vs
Operating time T₁Is the capacity C of the time constant control capacity 82 and the time constant control.
R, one of the resistors 81₁Using the value of   T₁= R₁Cln2 = ~ 0.693R₁C ...... Water pump standby time T when water pump is stopped_TwoIs the time constant
Corresponds to the discharge of control capacity 82,   T_Two= R_TwoCln2 = ~ 0.693R_TwoC ...... Respectively.   Especially T_TwoNote that the value will be large, but accurate
Time control is not required, so carbon resistance and electrolytic
It can be configured using a denser. For example T_Two= 30
(Min) about 10M for 200μF condenser
A resistor of Ω may be used. The diode 93 has a reverse resistor.
A material whose resistance value is equivalent to several tens MΩ to one hundred MΩ is prepared.
It is possible to find circuit elements having these values.   Standard astable multi using NE555 or ICM7555
The configuration of the vibrator excludes the diode 93 as is well known.
Circuit, but in that case T₁When charging for
Time T_TwoLonger than the discharge time corresponding to
Therefore, it is not suitable for the control of the water pump of the present apparatus. Note that
And when using the standard circuit, 3 pin output
T through the inverter circuit₁And T_TwoReversing the relationship of length
Need to be done. With a simple inverter circuit configuration
Also, those using NE555 or ICM7555 are also known.
ing. In the circuit in FIG. 11, the time constant control capacity
Removed 82, grounded pins 6 and 7, and stabilized pin 2
Reconnect to 3-pin output of multivibrator
And the inverted output appears on the 3-pin output of the IC.
This is input to the switch transistor and relay or
Control the motor directly. After all two NE555 or ICM
Since 7555 is used, these two parts are integrated.
Only NE556 or ICM7556 should be used.   More stable operation can be expected through the above examples
Is the method (i) using a water level sensor, especially
Example using the float switch and float chamber shown in
You. The method using the timer circuit in (ii) uses the device.
Continues and the power supply battery is exhausted and the electromotive force decreases
Since the time required for pumping changes, appropriate control time
Is difficult to determine. Prolong the time to operate the water pump
If it breaks, a lot of water overflows from the sump and the operating time is short
The reservoir is not full and the reservoir is empty by the next pumping.
The sound of the water noise is stopped. Water sound around the clock
I get tired of doing it, so I dare to take such a state
