Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an automatic liquid detergent supply device. In particular, the present invention relates to an automatic liquid detergent supply device that has a large operating space for the palm of the hand to receive the flowing liquid detergent, and that automatically supplies a fixed amount of liquid detergent without touching the hand.

[Conventional technology]

In recent years, with the improvement of living standards, toilets in homes and offices are equipped with liquid detergent dispensers instead of traditional soap dispensers, and liquid detergent can be dispensed by simply twisting the faucet or pressing a switch such as a button. As shown in FIG. 6, when using the device, the user extends his/her palm below the flow port 90 to receive the liquid detergent, and if the device hits the liquid detergent container 91, the user's hand may be injured. Things can happen.

In addition, as shown in FIG. 7, there is an outlet b provided at the bottom of a liquid detergent container a with a valve c on its peripheral wall.
A steel ball d supported by a spring e is built in at an appropriate location near the lower end of the flow tube b, and a plastic sheet f is provided on the outside corresponding to the valve c. set up,
Moreover, a liquid detergent supply device can be seen which is provided with a push rod h fitted into an electromagnetic coil g on the outside. In this method, liquid detergent i is poured into a flow tube b, passes through the valve c, and is filled in the flow tube b above the steel ball d, and the push rod h is induced by an electromagnetic coil g. Pushing the plastic sheet f, indirectly sealing the valve c and pushing down the steel ball d in the flow tube b, causing the liquid detergent remaining on the steel ball d to flow out, and furthermore, the spring e Due to the reaction of
The steel ball d is pushed back to a predetermined position so that the plastic sheet f is restored to its original state. If the plastic sheet f is pressed down for a long period of time, it will lose its elasticity and change in quality, making its ability to recover to its original state uncertain, and furthermore, the ability to press the liquid detergent i to flow out is lost. We become selfish.

The rear wall of 0b is fitted and combined so as to correspond to the missing part. The induction drive mechanism 40 and the supply mechanism 60 are housed in the lower space thus formed.

The induction drive mechanism 40 includes a motor means 4 having a cam 422 attached to the upper end of the rotating shaft of the motor 421 at an appropriate position on the upper surface of the bottom plate 41 of the housing 10.
2, and a pair of first support plates 411 provided at an appropriate position near the front of the housing 10.
By inserting a photoelectric induction circuit means 43 into the motor 421, the motor 421 is guided and activated when the palm approaches the liquid detergent outlet, and the push means 6 of the supply mechanism 60, which will be described later, is activated.
Corresponding to the armrest 613 provided at the side end of 1,
A micro switch 440 is provided at a suitable location on the induction circuit means 43 so that it can come into contact with the push means 61 when it is retracted, and the operation of the motor 421 is stopped when the push arm 613 presses it. has been done.

The supply mechanism 60 consists of a push means 61 and a pump means 62, and a push plate 611 of the push means 61 has a concave lower surface and is connected to the cam 42.
2, and is attached along the guide groove 617 on the lower side of the upper seat frame 616 so as to reciprocate as the cam 422 rotates, and on the side end thereof. The arc-shaped armrest 61
3, which is sandwiched between the seat frame 616 and the motor 421. are installed on the pair of second support plates 412 at corresponding heights, and the receiving port 622 at the other end is communicated with the flow port 13 provided at the bottom of the liquid detergent container of the housing 10, and Suction part 621
is in communication with a discharge pipe 623 to cause liquid detergent to flow out to an outlet 413 provided in the bottom plate 41.

As shown in FIG. 3, the device of the present invention is constructed by attaching the bottom plate 41, on which each of the mechanisms is installed on the upper surface, to the bottom of the housing 10 through the mounting holes 414. It is constructed by being accommodated in a space.

The entire induction electric circuit of the present invention, as shown in Fig. 4, includes a voltage adjustment circuit 431 that adjusts the voltage of a 110 or 220 volt AC power source to a voltage and power suitable for the motor, and a voltage adjustment circuit 431 that adjusts the AC voltage of the circuit. a bridge rectifier 432 that rectifies and converts the DC voltage into a DC voltage, and a silicon rectifier SCR4 that controls a switch device for the rectified DC voltage.

A production amplifier circuit 436 that outputs an amplified voltage signal; a photo transistor 437 that accepts light and generates a photoelectric effect and outputs it; a light emitting diode 438 that converts electrical energy into a luminous flux of a specific wavelength and emits it; an oscillation circuit 439 that emits vibration pulses, and a motor 4.
The microswitch 440 is controlled by a arm 613 that operates in accordance with the rotation of the arm 613.

That is, when the silicon rectifying element 433 is in an open state, the oscillation circuit is constantly emitting pulses, and the light emitting diode 438 emits a light beam of a specific wavelength, and when the object Q approaches, it emits a light beam of a specific wavelength. The light beam is reflected and reaches the light-receiving surface 4371 of the photo transistor 437, which generates a bias voltage that promotes conduction of the photo transistor 437 and outputs a photovoltage. The photovoltage passes through the operational amplifier circuit, has its waveform amplified, is output as a voltage signal, and proceeds to the detection circuit 435 where it is detected. Then, the voltage at point A is lowered from high voltage to low voltage, the signal of bistable circuit 434 is changed to high voltage, and the signal is received by silicon rectifying element 433, and the rotation operation of motor 421 of the induction driving means 40 is promoted. be. At the same time, the cam 422 installed thereon also rotates, and the push plate 61
1 performs a reciprocating operation, and after the cam 422 rotates once, the arm 613 protruding from the end of the push plate 611 presses the micro switch 440 to cut off the electricity, and the logic of the bistable circuit 434 is activated. The circuit is re-inputted with a low voltage to the switch of the silicon rectifying element 33, the silicon rectifying element 433 is stopped, the electricity to the motor 421 circuit is cut off, and the entire circuit is returned to its original state. When another object appears, the cycle is repeated once again.

To explain this using the liquid detergent automatic supply device of this embodiment shown in FIG. 5, when the palm approaches the guiding circuit means 43,
urges the motor 421 to rotate, and the cam 422 on the top also rotates, causing the push means 6 on the top surface to rotate.
The push plate 611 regulated by the seat frame 616 of 1 is caused to reciprocate, and the push plate 611
moves forward and the suction portion 621 of the pump means 62
When the detergent comes into contact with the suction part 621, the liquid detergent inside the detergent is sucked up by the suction part 621 and flows out, passes through the discharge pipe 623, and flows into the palm from the outlet 413. After the push plate 611 comes into contact with the suction portion 621, the cam 422 rotates further, the push plate 611 retreats, and the armrest 613 protruding from the side end touches the micro switch 440. As a result, the electricity to the motor 421 circuit is cut off and the original state is restored, and the amount of liquid detergent flowing out becomes almost constant.
