[0067] The following describes the embodiments of the present invention according to the accompanying drawings. In addition, in the following description, the same symbols are used to mark the same components, and the description of the components that have been described is appropriately omitted.

[0068] As mentioned above, in a fluid pump structure, when the pump is used only by turning it on / off, the maximum pressure of the pump cannot be transmitted at the beginning and end of spraying, so liquid overflow and liquid droplets may occur.

[0069] The disinfectant spray device of this embodiment can provide comfortable fine mist even at the beginning and end of spraying by controlling its parts with pumps and solenoid valves.

[0070] That is, the disinfectant spray device of this embodiment is triggered to spray (trigger on), and the pump is started to pressurize in a state where the electromagnetic valve is closed.

[0071] By opening the solenoid valve in a pressurized state, the spray can be started strongly to eliminate droplets at the beginning.

[0072] At the end of the spraying, the pump is rotated in reverse to lead the disinfectant inside the nozzle to stop the spraying, so that fine mist is generated instead of droplets.

[0082] Fig.10 For illustration Fig. 9 A diagram showing the control timing of opening and closing of the solenoid valve and rotation of the pump motor.

[0083] Fig.11 It is a functional block diagram of the disinfectant spray device 1.

[0084] The disinfectant spray device 1 of this embodiment is a device that automatically performs temperature measurement and disinfection by inserting a hand into a predetermined position in the hand insertion space 10a.

[0085] The disinfectant spray device 1 includes a space forming portion 10 for forming a hand insertion space 10a for placing a hand H, a first hand detection portion 21 and a second hand detection portion 22 for detecting the hand H, a temperature measuring portion 31 for measuring the temperature of the back of the hand H, a disinfectant spray portion 40 for spraying disinfectant on the palm of the hand H, a first light emitting portion 51 and a second light emitting portion 52, and a control portion 60 for controlling the operation of each portion.

[0086] The space forming portion 10 has a front opening 71 through which a hand can be inserted on the front side. The size of the front opening 71 is such that even if a hand H is inserted into the hand insertion space 10a of the space forming portion 10, it does not touch the inner side of the space forming portion 10. The front opening 71 is such a size or shape that even if an adult's hand H can be inserted, a child's head cannot be inserted.

[0087] A back opening 72 is formed on the back side of the space forming portion 10 to face the front opening 71. In this way, the back opening 72 can reduce the discomfort felt by the user when inserting the hand H from the front opening 71 into the hand insertion space 10a.

[0088] In the present embodiment, the space forming portion 10 is a space in a substantially rectangular parallelepiped shape whose front side smoothly draws a curve.

[0089] The bottom 82 of the hand insertion space 10a may be in a direction in which the bottom is slightly lowered relative to the horizontal line from the front to the rear in the insertion direction (depth direction) of the hand H. The angle of inclination relative to the horizontal line is about 5 degrees or more and about 45 degrees or less, preferably about 12 degrees. Thereby, the hand H can be naturally inserted into the hand insertion space 10a of the space forming part 10. In addition, the disinfectant sprayed into the space forming part 10 does not stay in the hand insertion space 10a, but easily flows to the inclined lower side.

[0090] A hand-shaped guide pattern 83 is formed on the bottom portion 82 as a mark for positioning the hand in the hand insertion space 10 a .

[0091] The space forming portion 10 is disposed, for example, at the upper end of the lower support 2. The lower support 2 may be installed on the floor and extend in the vertical direction. Advertisements and the like may be displayed on the surface side of the lower support 2.

[0092] Above the space forming portion 10 , an upper support column 3 on which advertisements or the like can be displayed is provided on the surface side.

[0093] like Figure 3 As shown, the first hand detection unit 21 is provided on the ceiling portion 81 on the side of the back side opening portion 72 at the center of the hand insertion space 10 a.

[0094] The first hand detection unit 21 is used to detect the distance (height direction distance) between the hand and the hand arranged in the hand insertion space 10a.

[0095] The second hand detection unit 22 is used to detect whether a hand has been inserted from the back.

[0096] The second hand detection unit 22 is provided on the ceiling 81 at a side closer to the back opening 72 than the first hand detection unit 21. The second hand detection unit 22 is used to detect a hand located in the hand insertion space 10a closer to the back opening 72 than the first hand detection unit 21.

[0097] The temperature measuring unit 31 is provided in the vicinity of the front opening 71 of the ceiling 81 .

[0098] The temperature measuring section 31 has both the inside of the hand insertion space 10 a and the outside of the hand insertion space 10 a on the front opening 71 side as the temperature measuring range.

[0099] The temperature measuring unit 31 is used to measure the temperature of the back of the hand H located at a predetermined position in the hand insertion space 10 a.

[0100] The temperature measuring unit 31 is provided on the ceiling portion 81 so as to face a portion of the guide pattern 83 corresponding to the vicinity of the wrist.

[0101] By arranging the temperature measuring unit 31 near the front opening 71, the temperature of the hand H inserted from the front opening 71 can be appropriately measured, and the distance from the injection port 40a arranged near the center can be ensured, so that the disinfectant can be prevented from being sprayed onto the temperature measuring unit 31. The temperature near the wrist can also be measured by the temperature measuring unit 31.

[0102] The temperature measuring unit 31 includes a plurality of temperature sensors arranged in a matrix. For example, each of the temperature sensors includes 8×8 temperature sensors, a total of 64. The temperature sensors are, for example, infrared sensors.

[0103] like Figure 1 and Figure 4 As shown, the bottom 82 of the hand insertion space 10a is provided with a spray port 40a of the disinfectant spray unit 40. The disinfectant is sprayed from the spray port 40a toward the ceiling 81 within a predetermined angle range. The disinfectant is sprayed over a wide range of the palm of the hand H.

[0104] At this time, since the spray port 40a and the palm of the hand H are within the predetermined distance range, the disinfectant will be sprayed on the entire palm of the hand H. When the hand H is too close to the spray port 40a, the spraying range will be narrowed. In this embodiment, based on the detection signal from the first hand detection unit 21, when the hand H and the first hand detection unit 21 are within the predetermined distance range, it is determined that the hand is at the predetermined position and temperature measurement and disinfectant spraying are performed.

[0105] The space forming portion 10 has a discharge structure for discharging the remaining disinfectant after being sprayed from the disinfectant spraying portion 40 and disinfecting to the outside of the hand insertion space 10a.

[0106] A plurality of injection ports 40a may be provided.

[0107] The following describes the mechanism and function of spraying disinfectant.

[0108] like Figure 6 As shown, the disinfectant is sprayed upward from the disinfectant spray unit 40 (injection port 40a).

[0109] like Figure 6 As shown, a hand insertion height limiting member 302 is detachably fixed near the front opening 71 of the hand insertion space 10a, and blocks an area of ​​a predetermined height upward from the bottom 82 near the front opening 71.

[0110] The hand insertion height limiting member 302 is transparent or translucent.

[0111] The hand insertion height limiting member 302 is installed at the front opening 71 at the initial stage of introducing the disinfectant spray device 1. This can prevent the user's palm from contacting the bottom 82. That is, the user can be guided to place the palm of the hand at a predetermined height from the bottom 82, and the disinfectant from the disinfectant spray unit 40 can be sprayed on the entire palm of the hand.

[0112] After a certain period of time has passed since the disinfectant spray device 1 was introduced, the user becomes accustomed to inserting the hand into the front opening 71 with the hand away from the bottom 82. Therefore, even if the hand insertion height limiting member 302 is removed, the user will remove the hand from the bottom 82 and insert the hand into the front opening 71. By removing the hand insertion height limiting member 302, an excellent aesthetic appearance can be achieved.

[0113] like Figure 7 As shown, a placement space 111 for placing the spray unit 109 is provided below the bottom 82 of the hand insertion space 10a.

[0114] like Figure 8 As shown, the spray unit 109 includes a motor pump 131 , a disinfectant spray portion 40 as a nozzle, and a solenoid valve 135 .

[0115] like Fig. 9 As shown, the motor pump 131 generates pressure to draw disinfectant from the tank 141 toward the disinfectant spray unit 40 .

[0116] The solenoid valve 135 is located on the flow path of the disinfectant between the motor pump 131 and the disinfectant spray unit 40 .

[0117] (Disinfectant spraying operation of disinfectant spray device 1)

[0118] The control unit 60 executes: a step of causing the motor pump 131 to rotate forwardly while the solenoid valve 135 is closed;

[0119] A step of opening the solenoid valve 135 while the motor pump 131 is rotating in a positive direction;

[0120] A step of stopping the rotation of the motor pump 131 while the solenoid valve 135 is open;

[0121] After stopping the motor pump 131, a step of starting reverse rotation of the motor pump 131 with the solenoid valve 135 opened; and

[0122] After this step, the solenoid valve 135 is closed.

[0123] The control of the control unit 60 is as follows: Fig. 9 As shown in the timing diagram.

[0124] like Fig. 9As shown, the control unit 60 starts the forward rotation of the motor pump 131 at the timing t1 in a state where the electromagnetic valve 135 is closed.

[0125] The electromagnetic valve 135 is switched from the closed state to the open state at the timing t2 when the motor pump 131 is rotating positively for the pressurizing time T1. The pressurizing time T1 is, for example, 500 ms.

[0126] Thus, the disinfectant liquid is drawn from the tank 141 by the pressure generated by the motor pump 131 and pressurized to a pressure greater than a certain value, flows out of the disinfectant liquid spray unit 40 through the solenoid valve 135 , and is strongly sprayed from the disinfectant liquid spray unit 40 .

[0127] The rotation of the motor pump 131 is stopped at a timing t3 after the spraying time T2 has elapsed from the timing t2.

[0128] At the timing t4 when the motor pump 131 is stopped for the stop time T3, the motor pump 131 is reversely rotated. The spray time T2 is, for example, 650 ms or 750 ms. The stop time T3 is, for example, 50 ms.

[0129] Thereby, the disinfectant in the vicinity of the disinfectant spraying unit 40 is introduced toward the housing 141 .

[0130] At the timing t5 after the reverse rotation for 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.

[0131] As described above, by setting the pressurization time T1 to be shorter than the spray time T2, the time interval for multiple people to insert their hands in sequence can be shortened. The spray time T2 can be fully ensured, and a high degree of disinfection function can be exerted. By setting the pressurization time T1, the maximum pressure of the pump can be transmitted when the spray starts.

[0132] By setting the stop time T3 to be shorter than the pressurization time T1 and the spraying time T2, the total time from pressurization to the completion of reverse rotation can be shortened. In addition, by setting the stop time T3, after the disinfectant sprayed during the spraying time T2 is sprayed, after being sprayed into the hand insertion space 10a, the unnecessary disinfectant can be returned.

[0133] By setting the reverse rotation time T4 to be shorter than the spray time T2, a high level of disinfection function can be achieved even if the above total time is shortened.

[0134] As described above, by controlling the motor pump 131 and the solenoid valve 135 through the control unit 60, the maximum pressure of the forward and reverse rotation of the pump can be transmitted to the disinfectant spray unit 40 when the spraying of the disinfectant starts and ends, thereby suppressing liquid overflow and the occurrence of droplets, and providing comfortable fine mist even when the spraying starts and ends.

[0135] That is, the disinfectant spray device of this embodiment is triggered by spraying, and the pump is started to pressurize under the state of closing the electromagnetic valve. The spray can be started strongly by opening the electromagnetic valve under the pressurized state to eliminate the droplets at the beginning.

[0136] At the end of the spraying, the pump is rotated in reverse to lead the disinfectant inside the nozzle to stop the spraying, so that no droplets are generated but fine mist is generated.

[0137] The temperature measuring function of the disinfectant spray device 1 is described below.

[0138] like Figure 1 As shown, a first light emitting unit 51 and a second light emitting unit 52 are provided on the ceiling portion 5 of the disinfectant spray device 1 .

[0139] The first light emitting portion 51 is provided at an edge portion on the rear side of the ceiling portion 5 , and the second light emitting portion 52 is provided at an edge portion on the front side of the ceiling portion 5 .

[0140] The control unit 60 determines that the hand H is at the predetermined position based on the conditions that all of the first condition that the first hand detection unit 21 detects the hand, the second condition that the first hand detection unit 21 does not detect the hand within a certain period of time after the second hand detection unit 22 detects the hand, and the third condition that the distance between the first hand detection unit 21 and the hand H is within a predetermined range when the hand H is inserted into the hand insertion space 10a are met.

[0141] When the control unit 60 determines that the hand H is at the predetermined position, the temperature measuring unit 31 measures the temperature of the hand, and then controls the disinfectant spray unit 40 to spray the disinfectant onto the palm of the hand H from the spray port 40 a.

[0142] That is, the control unit 60 makes the above determination, and determines that the hand H is not in the predetermined position when the hand is inserted from the back side opening 72. In addition, since the disinfectant is sprayed on the condition that the distance between the hand H and the first hand detection unit 21 is not within the predetermined range (the distance range from the disinfectant sprayed from the spray port 40a to the entire palm of the hand H), the entire palm can be properly disinfected.

[0143] The control unit 60 obtains temperature measurement information from the plurality of temperature sensors of the temperature measurement unit 31 , and extracts temperature measurement information showing a predetermined temperature range, and determines whether the human body temperature reflected by the hand is normal based on the extracted temperature measurement information.

[0144] The control unit 60 regards the situation where the third condition is met and the situation where the necessary temperature measurement information can be obtained to perform the above judgment as the situation where the fourth condition is met, and sets the first light emitting unit 51 to the first light emitting state.

[0145] Furthermore, when the fourth condition is not satisfied, the control unit 60 sets the first light emitting unit 51 to the second light emitting state.

[0146] When the body temperature reflected by the hand is within a predetermined normal range, the control unit 60 sets the second light emitting unit 52 to the third light emitting state.

[0147] When the body temperature reflected by the hand is outside a predetermined normal range, the control unit 60 sets the second light emitting unit 52 to the fourth light emitting state.

[0148] Here, although the hand detection unit and the temperature measurement unit are independently provided in this embodiment, these components can also be provided as an integral unit (by sharing a sensor or a sensor module). Thus, the hand detection unit and the temperature measurement unit only need to use one structure.

[0149] The positions of the disinfectant spraying unit, the temperature measuring unit, and the hand detecting unit in the space forming unit 10 may be changed appropriately.

[0150] A tank for storing disinfectant and a pump for supplying disinfectant from the tank to the disinfectant spraying unit 40 are provided on the upper support 3. By providing the tank and the pump on the upper support 3, the design of the disinfectant spraying device 1 is improved.

[0151] For example, after the control unit 60 determines that the hand H is at a predetermined position based on the detection values ​​obtained from the first hand detection unit 21 and the second hand detection unit 22, it measures the temperature of the hand H using the temperature measurement unit 31, and then issues a command to the pump 70 to supply the disinfectant from the tank 80 to the disinfectant spray unit 40, and spray the disinfectant from the spray port. By controlling the timing of spraying the disinfectant after the temperature measurement of the hand H is completed by the control unit 60, the influence of the spraying of the disinfectant on the temperature measurement can be suppressed.

[0152] The notification unit 90 has a wireless communication function such as "Bluetooth (registered trademark)", and wirelessly sends a notification signal to a communication device of a worker located far away from the disinfectant spray device 1. The communication device is a wearable terminal such as a smart watch or a terminal such as a smart phone.

[0153] By having a wireless communication function, even if a person is not nearby for monitoring, the vibration function of a smart watch can be used to notify a person whose body temperature exceeds a predetermined standard. Thus, a person working around the disinfectant spray device 1 can monitor while doing other work without staring at a monitor.

[0154] In addition, various settings of the disinfectant spray device 1 can also be performed through application software of a mobile terminal or the like. For example, the application software can be used to set certain conditions (temperature threshold) for notification or types of notification (color of light or type of sound, etc.), power on / off, etc., and the communication function of the mobile terminal can be used to send the settings to the control unit 360. In addition, the control unit 60 can also send information such as the value of the completed temperature measurement or the remaining amount of disinfectant to the mobile terminal, and display it through the application software. The application software can also have the function of the notification unit 90.

[0155] (Overall operation of the disinfectant spray device)

[0156] Fig.12 A flow chart illustrating the overall operation of the disinfectant spray device according to an embodiment of the present invention.

[0157] First, as shown in step S101, it is determined whether the hand H is located at a predetermined position in the hand insertion space 10a. Fig.13 to explain.

[0158] The control unit 60 determines whether a hand has been detected according to the detection signal from the first hand detection unit 21 , and proceeds to step S202 when it is determined that the first condition of detection has been met (step S201 ).

[0159] In step S202, the control unit 60 determines whether the second condition that the first hand detection unit 21 does not detect a hand within a certain period of time after the second hand detection unit 22 detects a hand is met based on the detection signals from the first hand detection unit 21 and the second hand detection unit 22. If it is determined that the second condition is met, the process proceeds to step S203.

[0160] The control unit 60 determines whether the third condition that the distance between the first hand detection unit 21 and the hand H is within a predetermined range when the hand H is in the hand insertion space 10a is met based on the detection signal from the first hand detection unit 21. When it is determined that the third condition is met (step S203), it is determined that the hand H is at a predetermined position (step S204).

[0161] When the control unit 60 determines that the hand H is located at the predetermined position, the temperature measurement unit 31 performs temperature measurement of the hand.

[0162] Thus, when the hand H is not inserted to the predetermined position, the hand detection unit 20 will not detect the hand H. This can avoid unnecessary temperature measurement or disinfection.

[0163] When the hand H is detected by the hand detection unit 20 , the temperature of the hand H is measured as shown in step S102 . The temperature measurement is performed by the temperature measurement unit 31 .

[0164] Next, as shown in step S103 , the control unit 60 determines whether the hand temperature measurement satisfies a certain condition based on the temperature measurement information obtained from the temperature measurement unit 31 .

[0165] Next, the process proceeds to step S104 . In step S104 , the disinfectant is sprayed from the disinfectant spray unit 40 toward the palm of the hand H. The control unit 60 measures time during the period during which the disinfectant is sprayed from the disinfectant spray unit 40 .

[0166] By controlling the timing of spraying the disinfectant after the temperature measurement of the hand H is completed by the control unit 60, the influence of the spraying of the disinfectant on the temperature measurement can be suppressed. Then, the spraying of the disinfectant is stopped.

[0167] The operation of step S104 is to use Fig.10 Thereafter, as shown in step S105, notification (completed) is made from the notification unit 90.

[0168] Next, as shown in step S106, it is determined whether the processing is completed. If it is not completed (No in step S106), the process returns to step S101 and the subsequent processing is repeated. On the other hand, if it is completed (Yes in step S106), the process ends.

[0169] During the above operation, the control unit 60 follows Figure 7 The light-emitting states of the first light-emitting unit 51 and the second light-emitting unit 52 are controlled under the conditions.

[0170] This allows for quick response to people with high body temperatures.

[0171] The first light emitting portion 51 and the second light emitting portion 52 may be arranged in the opposite manner or may be arranged at other positions.

[0172] In such a disinfectant spraying device 1, by positioning the hand H in the hand insertion space 10a, and detecting that the hand has been positioned at a predetermined position from the front opening 71 through the first hand detection unit 21 and the second hand detection unit 22, temperature measurement and disinfection actions are automatically performed. The predetermined position is predefined as a position suitable for temperature measurement and spraying disinfectant in the depth and height directions within the hand insertion space 10a. Therefore, temperature measurement can be performed with high accuracy, and disinfectant can be sprayed on the entire palm.

[0173] Since the hand H is inserted into the hand insertion space 10a when spraying the disinfectant, and the hand insertion space 10a is covered by the lower support 2 and the upper support 3, the disinfectant will not spill (spray) outside the space forming portion 10. Therefore, the disinfectant will not be sprayed onto the face of the person.

[0174] Furthermore, although the present embodiment and its application examples are described above, the present invention is not limited to such examples. For example, when a person skilled in the art appropriately adds, deletes, or changes the design of the constituent elements of the aforementioned embodiments or their application examples, or appropriately combines the technical features of the various embodiments, as long as they have the gist of the present invention, they are all included in the scope of the present invention.

[0175] The shapes of the space forming portion 10 and the hand insertion space 10 a in the above-mentioned embodiment are not particularly limited.

[0176] In addition, a plurality of disinfectant spraying units 40 may be disposed at different positions. Furthermore, the number and structure of the temperature measuring units are not particularly limited to the above-mentioned forms.

[0177] In addition, each thermometer measures temperature at a position directly below or directly above or at a position at a specific angle.

[0178] In the above-mentioned embodiment, although the case where the spray unit 109 is housed in the placement space 111 below the bottom 82 is illustrated, the spray unit 109 may be housed in a place other than below the bottom 82 .

[0179] Furthermore, a plurality of injection units 109 may be provided at different positions in the space forming portion 10 .

[0180] Furthermore, Fig. 9 The number of the solenoid valves 135 shown may also be plural.
