Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to disinfecting a finger or the like by sending a disinfectant solution stored in a tank to a nozzle by a pump to spray the disinfectant solution.
The present invention relates to a sterilization device that uses a built-in rechargeable battery as a power source.

(B) Conventional Technology Conventionally, this type of sterilizing apparatus is disclosed in Japanese Utility Model Publication No. 60-19706. Further, since such a sterilization device needs to be used for medical purposes in a hospital or the like, the applicant has developed a portable sterilization device using a rechargeable CADNICA battery as a power source. However, the sterilizer using the CADNICA battery has a problem that the performance deteriorates sharply after a predetermined number of times of use and the disinfecting solution is not sufficiently supplied to the object to be sterilized and the sterilizing effect decreases, so that it must be charged. I don't know, but I didn't know when.

(C) Problems to be solved by the present invention, in view of the above-mentioned problems that occur when a rechargeable battery is used as the power source of the sterilizer as described above,
The purpose is to provide a user-friendly sterilizer with the purpose of making it possible to know when to charge.

(D) Means for Solving the Problems For this purpose, the present invention includes a detection circuit that outputs a detection signal when detecting a sterilized object inserted into the device, and a coefficient circuit that counts the number of times of the detection signal. A pump drive circuit that drives the pump for a certain period of time based on a detection signal of the detection circuit to supply a disinfectant solution to the object to be sterilized; a memory circuit that presets and stores the usable number of times; and a stored value of the memory circuit. And a control circuit for activating the notification means when the coefficient contents of the coefficient circuit match.

(E) Action When a finger or the like is inserted into the sterilization chamber (5), the detection circuit (10) outputs a detection signal. At this time, the coefficient circuit (11) counts the number of detection signals, and when the count value matches the stored value of the memory circuit (14), the control circuit (15) outputs a signal to the notification circuit (16). , LED element (17) is turned on, CADNICA battery
Notify that charging in (18) is necessary.

(F) Example An example of the present invention will be described below with reference to the drawings. (1) is a tank for storing disinfectant such as alcohol, (2) is the tank
An electromagnetic pump for supplying the disinfectant solution in (1) to a nozzle (4) through a delivery pipe (3), the pump (2) being a photoelectric tube for a finger or the like inserted in a sterilization chamber (5) having a front opening. When it is detected by (6), it operates for about 3 seconds, and disinfectant is sprayed from the nozzle (4) to disinfect fingers and the like. The solenoid valve (7) is opened immediately after the pump (2) stops operating, and the disinfectant solution remaining in the nozzle (4) and its holder (8) is introduced into the tank (1) through the liquid recovery pipe (9). to recover.
The solenoid valve (7) is configured to open and close for about 2 seconds.

Next, explaining the electric control circuit of the present invention, (10) is a detection circuit consisting of the photoelectric tube (6) and the like, for detecting that a sterilized object such as fingers is inserted into the sterilization chamber (5). Output a detection signal. Reference numeral (11) is a counting circuit that counts the number of detection signals output from the detected circuit (10), and consequently counts the number of times the sterilizer is used. (12) is a pump drive circuit that drives the pump (2) for about 3 seconds by a detection signal output from the detection circuit (10), and (13) is a pump drive circuit in which the drive circuit (12) is a pump (2).
This is a solenoid valve drive circuit that drives the solenoid valve (7) for about 2 seconds when the drive is stopped. (14) is a memory circuit in which the CADNICA battery (18) is charged in advance, and then the number of times of use for which this sterilizer can be sufficiently operated, for example, 100 times is set and stored, (15) is stored in the counting circuit (11). Count value and memory circuit (14)
The pump drive circuit (12) when the stored value of
A control circuit that outputs a lock signal that locks the drive circuit (12) regardless of the presence or absence of the detection signal of the detection circuit (10) by inputting the lock signal to the pump drive circuit (12). ) Does not work. (16) is a notification circuit that is activated when the control circuit (15) outputs a lock signal, and the circuit (16) turns on the LED element (17) as notification means to charge the CADNICA battery (18). Notify the user of what is required. A buzzer or the like may be used instead of the LED element (17).

Next, the charging of the CADNICA battery (18) will be described with reference to FIG. First, when the plug (19) is connected to a commercial power source for charging, the voltage is lowered by the transformer (20), the drive transistor (21) is turned on, and the charging indicator lamp (22) is lit. At this time, if the backup switch (23) is closed and the power supply switch (24) to the device is opened, the CADNICA battery (18) starts charging. When the commercial power supply is connected, a reset signal is input to the counting circuit (11) to reset the count value of the counting circuit (11) to the initial value. When the charging is completed, the backup switch (23) is opened to prevent the CADNICA battery (18) from being consumed.

Reference numeral (25) is the entire electric control circuit of FIG. 2, and the sterilizer can be used by closing the power supply switch (24) after charging.

The present invention has the configuration described above, and its operation will be described below. First, when the photoelectric tube (6) detects that an object to be sterilized such as a finger is inserted into the sterilization chamber (5), the detection circuit (10) outputs a detection signal. The pump drive circuit (12) drives the pump (2) by the detection signal of the detection circuit (10), and the disinfectant solution in the tank (1) is passed from the nozzle (4) through the liquid delivery pipe (3) to the sterilization chamber.
(5) Spray inside to sterilize the body to be sterilized. After driving the pump (2) for about 3 seconds, the solenoid valve driving circuit (13) operates the solenoid valve (7) for about 2 seconds to drive the liquid recovery pipe (9) and the tank.
The disinfectant solution remaining in the nozzle (4) and its holder (8) in communication with (1) is recovered in the tank (1) through the solution recovery pipe (9). The counting circuit (11) adds 1 to the count value each time the detection signal of the detection circuit (10) is input. When the device is used 99 times in this way, the counting content of the counting circuit (11) becomes "100", which coincides with the content "100" preset and stored in the memory circuit (14). For this reason,
The control circuit (15) outputs a lock signal to the pump drive circuit (12) to deactivate the drive circuit (12).

Therefore, even if the detection circuit (10) outputs a detection signal, the pump (2)
Does not operate. Further, the alarm circuit (16) is activated by the lock signal output from the control circuit (15),
The ED element (17) is turned on to inform the user that the built-in CADNICA battery (18) needs to be charged.

Therefore, the administrator can charge the CADNICA battery (18) as described above.

(G) Effect of the Invention As described above, the present invention is very convenient for the administrator because the time when the power source built in the sterilizer should be charged can be easily grasped. In addition, it is possible to provide a portable sterilizer that uses a rechargeable battery as a power source.
