(Overall operation of disinfectant spraying device)
7 and 8 are flowcharts illustrating the overall operation of the disinfectant spraying device according to the embodiment.
Based on the detection signal from the first hand detection unit 21, the control unit 60 determines whether or not the hand H inserted into the hand insertion space 10a has been detected. If judged, it will progress to step S202 (step S201).
In step S202, based on the detection signals from the first hand detection unit 21 and the second hand detection unit 22, the control unit 60 detects a hand within a certain period of time after the second hand detection unit 22 detects a hand. It is determined whether or not the second condition that the first hand detection unit 21 does not detect a hand is satisfied, and if it is determined that the second condition is satisfied, the process proceeds to step S203.

Based on the detection signal from the first hand detection unit 21, the control unit 60 sets the condition that the hand H is within the hand insertion space 10a and the distance between the first hand detection unit 21 and the hand H is within a predetermined range. is satisfied (step S203), and if it is determined that the condition is satisfied, it is determined that the hand H is in a predetermined position (step S204).
When the controller 60 determines that the hand H is at the predetermined position, the temperature of the hand is measured by the temperature detector 31 (step S205).
As a result, the hand detection unit 20 does not detect the hand H unless the hand H is inserted to the predetermined position. This avoids unnecessary temperature measurement and disinfection.

Next, the control unit 60 determines whether or not the manual temperature measurement satisfies a certain condition based on the temperature measurement information acquired from the temperature measurement unit 31 . If it judges that a certain condition is not met (high temperature), it outputs an alarm.
Next, as shown in FIG. 5, the disinfectant is sprayed from the nozzle 40a toward the palm of the hand H (step S206). The controller 60 counts the time while the disinfectant is sprayed from the nozzle 40a.
The control unit 60 controls the timing so that the disinfectant is sprayed after measuring the temperature of the hand H, thereby suppressing the influence of the spraying of the disinfectant on the temperature measurement. Stop spraying disinfectant.

In the case of a negative determination (N) in steps S201 to S203, the process proceeds to step S301 shown in FIG.
Based on the detection signal from the third hand detection unit 121, the control unit 60 determines whether or not the hand H inserted into the hand insertion space 10a has been detected. If judged, it will progress to step S302 (step S301).
In step S<b>302 , based on the detection signals from the third hand detection unit 121 and the fourth hand detection unit 122 , the control unit 60 detects a hand within a certain period of time after the fourth hand detection unit 122 detects the hand. It is determined whether or not the fourth condition that the hand detection unit 121 of 3 does not detect a hand is satisfied, and if it is determined that the condition is satisfied, the process proceeds to step S304 (step S302).

Based on the detection signal from the third hand detection unit 121, the control unit 60 determines that the hand H is within the hand insertion space 10a and the distance between the third hand detection unit 121 and the hand H is within a predetermined range. It is determined whether or not the condition is satisfied, and if it is determined that the condition is satisfied (step ST303), it is determined that the hand H is in a predetermined position (step ST304).
When the controller 60 determines that the hand H is at the predetermined position, the temperature of the hand is measured by the temperature detector 31 (step S305). If it judges that a certain condition is not met (high temperature), it outputs an alarm.
As a result, the hand detection unit does not detect the hand H unless the hand H is inserted to the predetermined position. This avoids unnecessary temperature measurement and disinfection.

Next, the control unit 60 determines whether or not the manual temperature measurement satisfies a certain condition based on the temperature measurement information acquired from the temperature measurement unit 31 .
Next, as shown in FIG. 6, the disinfectant is sprayed from the nozzle 140a toward the palm of the hand H (step S306). The controller 60 counts the time while the disinfectant is sprayed from the nozzle 140a.
The control unit 60 controls the timing so that the disinfectant is sprayed after measuring the temperature of the hand H, thereby suppressing the influence of the spraying of the disinfectant on the temperature measurement. Stop spraying disinfectant.

As described above, according to the disinfectant spraying device 1, even if the user inserts the hand H through either the front-side opening 71 or the back-side opening 72, temperature measurement and disinfection can be performed appropriately.

As described above, in the one-fluid pump structure, if the pump is used only by turning the pump on and off, the maximum pressure of the pump is not transmitted at the start and end of spraying, and drips and droplets occur.
The antiseptic solution spraying device of this embodiment controls the pump and the electromagnetic valve to provide a comfortable fine mist even at the start and end of spraying.

That is, the disinfectant spraying device of the present embodiment starts the pump to pressurize with the solenoid valve closed when the spraying trigger is turned on.
By opening the solenoid valve in a pressurized state, the atomization begins vigorously, eliminating liquid droplets at the start.
At the end of spraying, the pump is reversely rotated to draw back the disinfectant solution inside the nozzle, thereby interrupting the spraying and generating a fine mist without generating liquid droplets.

FIG. 9 is a diagram for explaining the rear configuration of the disinfectant spraying device 1 with the rear cover opened.
10A and 10B are diagrams for explaining a mechanism for sending the disinfectant to the disinfectant spray section 40. FIG.
FIG. 11 is a functional block diagram of the injection unit 109 including the disinfectant spray section 40. As shown in FIG.
FIG. 12 is a diagram for explaining control timings for opening/closing the electromagnetic valve shown in FIG. 11 and rotation of the motor of the pump.
FIG. 13 is a functional block diagram of the disinfectant spraying device 1. As shown in FIG.

The mechanism and function of spraying the disinfectant will be described below.
As shown in FIG. 9, a storage space 111 for storing the spray unit 109 is provided below the bottom 82 of the hand insertion space 10a.
As shown in FIG. 10 , the spray unit 109 has a motor pump 131 , a disinfectant solution spray section 40 that is a nozzle, and an electromagnetic valve 135 .

As shown in FIG. 11 , the motor pump 131 generates pressure to suck up the disinfectant from the tank 141 toward the disinfectant spray section 40 .
The solenoid valve 135 is positioned on the disinfectant fluid flow path between the motor pump 131 and the disinfectant spray unit 40 .

(Disinfectant spraying operation of disinfectant spraying device 1)
The control unit 60 rotates the motor pump 131 forward while the solenoid valve 135 is closed;
a step of opening the solenoid valve 135 while the motor pump 131 is rotated forward;
stopping rotation of the motor pump 131 with the solenoid valve 135 open;
a step of starting reverse rotation of the motor pump 131 with the solenoid valve 135 open after the motor pump 131 is stopped;
After this step, a step of closing the solenoid valve 135 and are performed.

The control of the control section 60 described above is shown in the timing chart of FIG.
As shown in FIG. 12, the control unit 60 starts forward rotation of the motor pump 131 at timing t1 with the solenoid valve 135 closed.

The electromagnetic valve 135 is switched from the closed state to the open state at timing t2 when the motor pump 131 rotates forward for the pressurization time T1. Pressurization time T1 is, for example, 500 ms.
As a result, the disinfectant pumped from the tank 141 by the pressure generated by the motor pump 131 and pressurized at a certain pressure or higher flows through the solenoid valve 135 to the disinfectant spray section 40, and the disinfectant spray section 40 It is jetted vigorously.

The rotation of the motor pump 131 is stopped at timing t3 after the spray time T2 has elapsed from timing t2.
At timing t4 when the motor pump 131 is stopped for the stop time T3, the motor pump 131 is reversely rotated. Spray time T2 is, for example, 650 ms or 750 ms. Also, the stop time T3 is, for example, 50 ms.
As a result, the disinfectant near the disinfectant spray section 40 is drawn toward the tank 141 .

At timing t5 after the reverse rotation time T4, the electromagnetic valve 135 is switched from the open state to the closed state. The reverse rotation time T4 is, for example, 50 ms.

As described above, by making the pressurization time T1 shorter than the spray time T2, it is possible to shorten the time interval in which a plurality of people's hands can be sequentially inserted. Moreover, the spraying time T2 can be sufficiently ensured, and a high disinfection function can be exhibited. Further, by providing the pressurization time T1, the maximum pressure of the pump can be transmitted at the start of spraying.

By making the stop time T3 shorter than the pressurization time T1 and the spray time T2, the total time from pressurization to completion of reverse rotation can be shortened. In addition, by providing the stop time T3, unnecessary disinfectant can be returned after the disinfectant sprayed in the spraying time T2 is discharged into the hand insertion space 10a.

By making the reverse rotation time T4 shorter than the spray time T2, a high disinfecting function can be exhibited even if the total time is shortened.

As described above, by controlling the motor pump 131 and the solenoid valve 135 by the control unit 60, the maximum pressure of the forward and reverse rotation of the pump can be transmitted to the antiseptic solution spraying unit 40 at the start and end of spraying of the antiseptic solution. It suppresses the occurrence of dripping and droplets, and provides a comfortable fine mist even at the start and end of spraying.

That is, the disinfectant spraying device of the present embodiment starts the pump to pressurize with the solenoid valve closed when the spraying trigger is turned on. By opening the solenoid valve in a pressurized state, spraying starts vigorously and liquid droplets at the start can be eliminated.
At the end of spraying, the pump is reversely rotated to pull back the disinfecting liquid inside the nozzle, thereby interrupting the spraying and generating a fine mist without generating liquid droplets.

FIG. 14 is an enlarged view of the vicinity of the front opening 71 shown in FIG.
The antiseptic solution is sprayed upward from the antiseptic solution spray part 40 (40a).
As shown in FIG. 14, in the vicinity of the front opening 71 of the hand insertion space 10a, there is a hand insertion height regulating member 302 that blocks an area of a predetermined height upward from the bottom 82 of the front opening 71. Detachably fixed.
The hand insertion height regulating member 302 is transparent or translucent.

The hand insertion height regulating member 302 is attached to the front side opening 71 at the initial stage of introduction of the disinfectant spraying device 1 . This prevents the user from touching the bottom portion 82 with the palm of the hand. That is, it is possible to guide the user to position the palm at a predetermined height from the bottom portion 82 and spray the disinfectant from the disinfectant spray section 40 over the entire palm.
In addition, after a certain period of time has passed since the introduction of the disinfectant spraying device 1, and after the user has become accustomed to inserting the disinfectant solution spraying device 1 into the front side opening 71 with the hand released from the bottom 82, the hand insertion height regulation member Even if 302 is removed, the user releases the bottom part 82 and inserts it into the front side opening 71 . By removing the manual insertion height regulating member 302, an excellent appearance can be exhibited.

Also, a hand insertion height restricting member similar to the hand insertion height restricting member 302 may be provided near the rear side opening 72 .
Here, in this embodiment, the hand detection unit and the temperature detection unit are separately provided, but they may be integrated (shared by one sensor or shared by one sensor module). As a result, the hand detection section and the temperature detection section can be combined into one configuration.

The positions of the disinfectant solution spraying section, the temperature measuring section, and the hand detecting section within the space forming section 10 can be changed as appropriate.

The upper support column 3 is provided with a tank for containing the disinfectant and a pump for supplying the disinfectant from the tank to the disinfectant spraying units 40a and 40b. By providing the tank and the pump in the upper column 3, the design of the disinfectant spraying device 1 is enhanced.

For example, after the control unit 60 determines that the hand H is at a predetermined position based on the detection vision acquired from the first hand detection unit 21 and the second hand detection unit 22, the temperature of the hand H is measured by the temperature detection unit 31. After that, an instruction is given to the pump 70 to supply the disinfectant solution from the tank 80 to the disinfectant solution spraying unit 40, and control is performed to inject the disinfectant solution from the injection port. The control unit 60 controls the timing so that the disinfectant is sprayed after measuring the temperature of the hand H, thereby suppressing the influence of the spraying of the disinfectant on the temperature measurement.

The notification unit 90 has a wireless communication function such as Bluetooth (registered trademark), for example, and transmits a wireless notification signal to the communication device of the staff at a location away from the disinfectant spraying device 1 . The communication device is a wearable terminal such as a smartwatch or a terminal such as a smartphone.
By installing a wireless communication function, it is possible to notify that there is a person whose body temperature exceeds a predetermined standard by the vibration function of a smart watch, etc., even if there is no human monitoring nearby. As a result, those who work around the disinfectant spraying apparatus 1 can monitor the situation while doing other work without looking at the monitor or the like.

Various settings of the disinfectant spraying device 1 may be performed by application software such as a mobile terminal. For example, application software can be used to set certain conditions (temperature threshold), type of notification (color of light, type of sound, etc.), power ON/OFF, etc., and send settings to the control unit 60 using the communication function of the portable terminal. You can send it. Further, the control unit 60 may transmit information such as the measured temperature value and the remaining amount of disinfectant to the mobile terminal and display the information using application software. The application software may have the function of the notification unit 90 .

In such a disinfectant solution spraying device 1, by positioning the hand H in the hand insertion space 10a, the hand detection unit detects that the hand is positioned at a predetermined position from both the front side opening 71 and the back side opening 72. After detecting, temperature measurement and disinfection are automatically performed. The predetermined position is preliminarily defined as a position suitable for temperature measurement and antiseptic solution spraying in the depth and height directions in the hand insertion space 10a. Therefore, the temperature can be measured with high accuracy, and the disinfectant can be sprayed over the entire palm.

Since the hand H is inserted into the hand insertion space 10a and the hand insertion space 10a is covered with the lower strut 2 and the upper strut 3 when the disinfectant is sprayed, the disinfectant leaks to the outside of the space forming part 10. (Blows out) There is no such thing. Therefore, the disinfectant does not come into contact with people's faces.
