The present invention relates to a cosmetic liquid dispenser capable of easily withdrawing various cosmetics such as skin, lotion, shampoo, rinse, hair liquid, and more particularly, to a cosmetic liquid dispenser that can be used regardless of high viscosity and low. .

Conventionally, liquid dispensers have been proposed in US Pat. No. 4,921,131 (hereinafter referred to as "quote citation"). This is to provide a valve that opens and closes by sensing the access of the hand to the lower side of the bag containing the sanitary solution to be used to draw out the sanitary solution by quantity. The liquid dispenser according to the cited invention detects when the user approaches the hand by the infrared light-emitting emitter, and the valve is opened for a time corresponding to a preset amount by the user to quantitatively flow down the sanitary solution contained in the bag. It was to be withdrawn. This cited invention is such that when the valve is opened, the liquid contained in the hygiene liquid bag flows into gravity.

In order to achieve the above object, the present invention detects the approach of the user's hand to be discharged to the liquid bag of the liquid known in the downward direction, by detecting the approach of the hand to rotate the motor forward and backward, and the power We propose a multipurpose liquid dispenser that allows the valve to inhale and discharge the liquid in the liquid reservoir so that a fixed amount of liquid can be discharged regardless of the viscosity.

By the above-described configuration, the present invention can be used irrespective of viscosity, thereby providing a multi-purpose liquid dispenser that can be widely used for various purposes.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in Figs. 1 and 2, the present invention provides an access sensing unit 3 including an infrared light emitting diode 1 and an infrared light receiving diode 2, and a liquid storage container 3 as an output of the access sensing unit 3. In the well-known thing which discharged the liquid solution in) by quantity,

The servomotor 4, which is operated in the forward and reverse directions, the rack gear 5 for elevating a predetermined section by the rotational force of the servomotor 4, and the rack gear 5 are pulled upwards and have their own elasticity. The suction valve bracket 8 is fixed to both sides of the corrugated pipe 6 which is closed upward and is opened downward, and is fixed to both sides of the conduit 7 passing through the corrugated pipe 6 downward, respectively, and has holes 35 and 35 ', respectively. And the suction valve bracket (9) and the suction valve bracket (9) and the suction valve bracket (8) and the discharge valve bracket (9) by being pulled and coupled by the expansion rope (10) and fixed by the circular jaw (13) and the discharge valve. And a first timer (15) having a variable resistor (14) for setting a time for which power is supplied to the servomotor (4) in a positive direction for a predetermined time. To the servomotor 4 by the second timer 16 and the first timer 15 and the second timer 16 having a variable resistor 14 'for the first time. It is provided with a control circuit of the switching means 26 for supplying a circle. Reference numeral 17 is an outlet port, and 37 is a guide plate body for supporting the rack gear 5 and guiding the lifting.

When the user approaches the hand between the infrared light emitting diodes 1 and the infrared light emitting diodes 2, the light of the light emitting diodes 1 that is diffused and extinguished by the user is reflected on the user's hands to reflect the infrared light emitting diodes. It is incident on (2). Therefore, the infrared light-emitting diode 2 is turned on and thus the switching transistor is turned on. Therefore, the charge charged in the capacitor 18 connected to the collector thereof is discharged, and the input of the first timer 15 is brought to the low level.

Therefore, the first timer 15 outputs a signal output maintained for the time set by the variable resistor 14, and the switching means 26 drives the servomotor 4 in the forward direction during the time during which the signal output is maintained. Will be done.

Accordingly, as the servomotor 4 rotates the pinion 19, the rack gear 5 is rotated. Therefore, the upper end of the corrugated pipe 6 fixed above the rack gear 5 is upward. Pulled to expand the corrugated pipe 6, this state is the result of the pressure inside the corrugated pipe 6 is lower than before.

Therefore, as the expansion rope 10 is extended, the suction valve 11 is pulled inward, and the solution of the liquid storage container 3 is sucked into the conduit 7 through the through hole 35 of the suction valve bracket 8. 3 is shown.

Subsequently, when the time set by the variable resistor 14 of the first timer 15 elapses, the output becomes low level, and thus the power supply of the servo motor 4 supplied through the switching means 26 is cut off. . Subsequently, when the input reaches the low level, the second timer 16 inverts the output to the high level and maintains the high level output for the time set by the variable resistor 14 '. Therefore, power is supplied to the servo motor 4 in the opposite direction to the conventional one by the switching means 26, so that the servo motor 4 is reversely rotated.

Accordingly, the pinion 19 of the servomotor 4 is rotated in the opposite direction as before, so as to rotate the rack gear 5 downward, so that the upper end of the corrugated pipe 6 is downward. It is pressed. Accordingly, while the corrugated pipe 6 is compressed, the pressure therein increases. As a result, pressure is applied to the intake valve 11 due to the increase in the pressure inside the corrugated pipe 6, which is in close contact with the intake valve bracket 8 and becomes sealed, while the through hole 35 'of the discharge valve bracket 9 is closed. As the pressure increased through the discharge valve 12 overcomes the elasticity of the stretchable rope 10 and is pushed to the right in the drawing, the liquid in the conduit 7 rapidly discharges the bracket 9 and the discharge valve ( 12) and discharge through the outlet 17, this state is shown in FIG.

After this operation, the signal supply to the switching means 26 is lost after a time set by the variable resistor 14, so that the servo motor 4 is no longer rotated, and thus the corrugated pipe 6 has its own elasticity. It will be returned to the original position and the rack gear 5 will also be returned to the state shown in Fig. 2, which will return to the original position and wait for the next operation.

In addition, although the first and second timers of the control circuit used in the present invention may be used in various forms, specifically, a combination of an inverter and a capacitor variable resistor may be used.

This embodiment is shown in FIG. As can be seen from the present invention, the condenser 24 is connected to the input side of the first inverter 20 of the first timer 15, and the input of the second inverter 21 is connected to the output side via the condenser 24 '. And the grounded variable resistor 14 are connected, and the output side of the second inverter 21 is connected to the input side of the first inverter 20 through the diode 25 connected in the reverse direction.

In addition, the output side of the first timer 15 is connected to the input side of the second timer 16 and the switching means 26, and the switching means 26 includes the first transistor 27, the auxiliary transistors 29, 30 and the first transistor. It is connected to two transistors 28 and auxiliary transistors 31 and 32.

In addition, the second timer 16 has a capacitor 24 '' connected to an input side of the third inverter 22 and a variable ground connected to the input of the fourth inverter 23 through the capacitor 24 '' 'on the output side. The resistor 14 'is connected, and the output side of the fourth inverter 23 is connected to the input side of the third inverter 22 via the diode 25' connected in the reverse direction.

In this embodiment, when the user approaches the hand and the output is generated in the infrared light emitting diode 2, the transistor 18 is turned on and the capacitor 24 is discharged. Accordingly, the first inverter 20 of the first timer 15 is generated. As the input becomes low level and the output becomes high level, the first transistor 27 of the switching means 26 is turned on so that the auxiliary transistors 29 and 30 are turned on, thereby rotating the servomotor 4 in the forward direction. Therefore, as described above, the corrugated pipe 6 extends and the pressure in the corrugated pipe 6 decreases, so that the liquid of the liquid storage container 3 is sucked.

In this state, the charge of the capacitor 24 'is discharged through the variable resistor 14, and the time required for the discharge is determined by the value adjusted by the variable resistor 14. Therefore, the servomotor 4 is moved in the positive direction. Rotation time is determined. Subsequently, when the time set by the variable resistor 14 has elapsed, all of the charging voltages of the capacitor 24 'are discharged, so that the output of the first timer 15 becomes low level. This low level output turns off the first transistor 27 of the switching circuit and puts the capacitor 24 of the second timer 16 into a discharged state. Therefore, the input of the third inverter 22 of the second timer 16 is at the low level, and thus the output is at the high level. As a result, this time, the second transistor 28 is turned on and the auxiliary transistors 31 and 32 are turned on so that a reverse current flows in the servomotor 4, and the servomotor 4 is reversely rotated to corrugate pipe 6. Press to compress and pressurizes the suction valve 11 as the pressure inside thereof increases, which is in close contact with the suction valve bracket 8 and becomes sealed. The discharge valve 12 is pushed to the right in the drawing while the discharge valve 12 is pushed to the right in the drawing while the pressure increased through the 35 'is applied to the discharge valve bracket 9 and the discharge valve bracket 9 at a high speed. It is discharged through the discharge valve 12 and the discharge port (17).

When the time elapses in this state, the charge charged in the large capacitor 24 '' 'is discharged as the time set by the variable resistor 14' elapses and the output of the third inverter 22 becomes low level. As a result, the outputs of the first timer 15 and the second timer 16 are both at a low level, and the servo motor 4 is in a standby state in which no power is supplied. As described above, in the present invention, the suction and discharge operation time by the servo motor is set for the time set by the variable resistors 14 and 14 'so that a series of operations for sucking and discharging the liquid into the pipeline 7 is optimal. Can be brought to a state.

In addition, in the present invention, the light emitting diodes 34 are turned on during the time when the servo motor is rotated in the forward direction, and the light emitting diodes 33 are turned on during the time when the servo motor is turned in the reverse direction.

In this way, the present invention can be used even when the viscosity of the liquid is low, as well as when the viscosity is high, so that it can be widely used for various purposes, and thus the utility can be expanded.

In addition, since the present invention uses a motor, power consumption is very low as compared to the conventional one using a solenoid, and thus, a battery replacement cycle is lengthened, thereby greatly reducing maintenance and repair costs.

In addition, the present invention is very concise in structure and can be widely spread by lowering the manufacturing cost, it provides an effect such as a very low failure rate.
