The present invention relates to a disinfectant spray device, and more particularly, to an automatic hand disinfectant spray device that detects a hand that enters a lower part of a sterilizer and sprays an appropriate amount of disinfectant solution on a hand.

In the conventional automatic hand sanitizer spray device as shown in Figure 1 by the control signal of the central control unit 105, the infrared signal of the infrared diode installed below the disinfectant reservoir 108 to the pulse signal generated by the infrared signal driver 102 If the user waits in the continuous firing state by the light emitting unit 101 and enters the hand within the range of the infrared light emitting unit 101, the infrared signal is reflected by the hand and is incident on the infrared light receiving unit 103. As a result, the weak signal incident on the infrared light receiving unit 103 is amplified by the signal amplifying unit 104 to a sufficient magnitude and applied to the central control unit 105. In order to spray the disinfectant solution, a signal for operating the motor driver 106 is output and the motor driver 106 is driven by the signal to operate the motor pump 107 below the disinfectant storage tank 108 to operate the disinfectant storage tank 108. Disinfectant solution will be supplied to the hands below.

        When the disinfectant is being supplied in this manner, if the user removes his or her hand, the infrared light receiving unit 103 stops receiving the infrared signal, and the central control unit 105 recognizes that the hand is gone and immediately stops the supply of the disinfectant solution. Stop operation. In the known device configured as described above, since the disinfectant solution is continuously sprayed from the time of entering the hand until the hand is removed, the amount of unnecessary loss required for disinfecting the hand is not accurately measured.

         In addition, when the hands are inserted by the same configuration, the motor is operated by the central control unit, and the cam of the motor is rotated once so that the spray pump is pressed once so that a certain amount of disinfectant solution is sprayed every time the hands are inserted. This is because the amount of single injection is irregular and its amount is often insufficient, so it is inconvenient to use it because the proper amount must be injected by entering the hand as many times as necessary.

It is an object of the present invention to solve the problems described above, since the amount of hand disinfectant used may vary from place to place, and the amount of one injection is set appropriately in each place to preset the hand every time. If you need more disinfectant solution, if you need more disinfectant solution, do not remove the hand and continue to spray again, but the automatic hand disinfectant solution that can be sprayed once and repeatedly with a predetermined adjustable injection time difference It is for providing a device.

         In order to solve this problem, the hand disinfectant solution is sprayed by continuously outputting the output signal for driving the motor pump until the hand is released when the sensor installed under the automatic hand disinfection device detects that the hand has been released. The injection volume setting unit for setting the single injection amount of the disinfectant solution to the central control unit of the device, the indicator for displaying the stage of the injection amount, and if the hand is continuously detected, to allow the continuous injection by the time difference with the time difference. In order to propose an automatic hand sanitizer spraying device by connecting the time difference control unit.

        Accordingly, the present invention, even if the detection sensor continues to detect the hand is to spray a minute amount of the disinfectant solution set in accordance with the actual situation of the place of use, with a time difference, using a suitable amount suitable for the place of use Disinfection can be used economically by reducing the waste of disinfectant solution.

        The present invention will be described with reference to the accompanying drawings.

Figure 2 is a block diagram showing the configuration of the automatic hand sanitizing solution injection apparatus according to the present invention.

As can be seen from this automatic hand disinfectant spray device is an infrared signal driver 202 which is operated to emit infrared rays under the control of the central control unit 205 to detect that the hand disinfectant solution supply is below the hand. ) And an infrared light emitting unit 201, an infrared light receiving unit 203 for receiving infrared rays reflected by the entered hand, and a received signal amplifying unit 204 for amplifying and transmitting the received signal to the central controller 205. And a known disinfectant solution of the disinfectant solution tank 210 is sprayed by the motor driver 208 controlled by the central controller 205, the motor pump 209, the solenoid driver 206, and the solenoid valve 207. In the automatic hand sanitizer spray device,

The injection amount setting unit 213 made of a variable resistor or a tack switch to adjust the opening time of the motor pump 209 and the solenoid valve 207 to adjust the injection amount to the central control unit 205, and the time passes by the hand entering As a result, the injection time difference setting unit 212 for setting the time at which injection is started again and the indicator 211 for displaying the value set by the aforementioned injection amount setting unit 213 are connected.

        In this way, the present invention should set a single injection amount before operation. To this end, the user sets the optimal injection amount according to the installation place by looking at the number that is changed by the indicator 211 while operating the injection amount setting unit 213. In other words, one group of children should be given small injections, and one group of soldiers should have several injections, and other food manufacturers, drug manufacturers, medical institutions, etc. The optimum injection amount is to be set.

In addition, by operating the injection time difference setting unit 212, if the entry state of the hand is maintained so that the set time elapses in preparation for the case where the single injection amount is insufficient, the set amount of disinfectant solution is set to be repeated again.

       After doing this, when the normal operation is started, the infrared light emitting unit 201 made of an infrared diode installed below the disinfectant reservoir 210 receives the pulse signal generated by the infrared signal driver 202 by the control signal of the central control unit 205. If the user waits in the continuous firing state by the light beam and enters the hand within the range of the infrared light emitting unit 201, the infrared signal is reflected by the hand and is incident on the infrared light receiving unit 203. Accordingly, the weak signal incident on the infrared light receiving unit 203 is amplified by the signal amplifying unit 204 to a sufficient magnitude and then applied to the central control unit 205. Accordingly, the central control unit 205 recognizes that a hand has entered. The solenoid valve 207 installed below the disinfectant reservoir 210 is opened by the respective currents output by driving the solenoid driver 206 and the motor driver 208 to spray the hand disinfectant solution and at the same time the motor pump 209. Is operated to start dispensing the disinfectant solution of the disinfectant reservoir 210 toward the hand below, wherein the central control unit 205 refers to the set value by the injection amount setting unit 213 and corresponds to the set value. Only while driving the motor pump 209 and the solenoid 207. Therefore, the solenoid valve 207 and the motor pump 209 inject the disinfectant solution in an amount corresponding to one time and stop the operation. In addition, when the injection of the disinfectant solution for one batch is completed and the amount of injection is insufficient and the injection is required again, the central control unit 205 recognizes that the entry of the hand is maintained so that a predetermined time elapses after the entry of the hand. Since the set time of the time difference setting unit 212 has elapsed, the central control unit 205 again performs the above-described operation so as to spray the disinfectant solution. 3 is shown.

       As shown in this figure, the start step is to start the flow chart of the device, and the On switch is to turn off the power supply and stop the operation. When the power is supplied, all operations are normally executed. The detection signal input step is a step in which a signal is input to the infrared light receiving unit 203, amplified and applied to the central control unit 205, and the hand entry data input step is performed to determine whether the input signal is a normal signal or not. In this case, the infrared signal driver 202 carries a pulse signal having a predetermined width and period on the transmission wave to drive the infrared light emitting unit 201, and the infrared light receiving unit 203 is used to control the hand. When the received signal is received by the received signal amplification unit 204 through the signal amplification and detection process is applied to the central control unit 205 and the center Fisherman 205, it will be able to determine if the same width and the pulse cycle signal is applied to read out by the noise due to the external light if a normal monitor signal with one hand the input signal transmission signal. In this way, if it is determined that the signal due to noise, the process returns to the hand detection signal input step and continues to wait, and when it is determined that the hand is normally detected, the central controller 205 controls the solenoid drive unit 206 in the next step so that the solenoid valve ( 207 is opened, and then the motor driving unit 208 is controlled to drive the motor pump 209, and spraying is performed for the time set by the injection amount setting unit 213, and the central control unit 205 performs the injection amount setting unit ( It counts whether the time corresponding to the amount set in step 213 has elapsed.

         If the process has not yet elapsed, the solenoid driving unit 206 and the motor driving unit 208 continue to be driven, and if a time corresponding to the amount set by the injection amount setting unit 213 has elapsed, a single disinfectant solution is injected. As a result, the solenoid drive unit 206 and the motor drive unit 208 are stopped. Subsequently, after the time set by the injection time difference setting unit 212 has elapsed, the central control unit 205 drives the infrared signal driver 202 to emit an infrared signal to the infrared light emitting unit 201, and is reflected by the hand to receive the received signal. The infrared signal is detected by the infrared light receiver 203. In this case, when the fact that the hand is entered is detected by the above-described process, the disinfectant is re-injected for the time set by the injection amount setting unit 213 again, and when the hand is taken out, the operation as described above to detect the hand entry. Will be repeated. Therefore, if the user puts his hand up to the time when the desired amount of disinfectant is injected, the disinfectant solution is sprayed by the amount set by the injection amount setting unit 213 at the time interval set by the spraying time difference setting unit 212, and the desired amount Disinfectant solution can be sprayed.

In addition, the above-described injection time difference setting unit 212 may be arbitrarily determined by the designer and may not be separately installed. In this case, it is practical to set the program of the central control unit 205 so that the time difference is about 3 seconds.

Accordingly, the present invention is that even if the detection sensor continues to detect the hand to be sprayed once each time the amount of disinfectant set to meet the situation of the use place, using the optimum amount suitable for the use place and situation Reasonable hand disinfection is possible, and it is economical by eliminating discomfort in use and reducing waste of disinfectant solution.

In addition, since the disinfectant solution is not dropped, but is sprayed for a predetermined time, the disinfectant solution can be easily spread evenly over the entire area of the hand, so that the disinfecting solution can be quickly and evenly performed.
