[0022] The following combines the attachedFigures 1-3 A further description is given to the non-contact elevator button device.

[0023] Embodiment 1

[0024] A non-contact elevator button device includes: a slide rail 13, a mounting seat 15, an infrared reflection sensing module 17, a control board 18, a disinfection device 19, a fixed frame 20. A plurality of the slide rails 13 are detachably connected to the fixed frame 20. A plurality of the mounting seats 15 are detachably and slidably connected to the slide rails 13. The infrared reflection sensing module 17 is mounted on the mounting seat 15. The infrared reflection sensing module 17 is electrically connected to the control board 18.

[0030] Further, the chip model of the control board 18 is LM339.

[0031] Further, the fixed frame 20 has a chamfer, and the ultraviolet lamp 19 is mounted inside the chamfer.

[0032] See Figure 1 、 Figure 2。This embodiment provides an elevator button auxiliary device. The fixed frame 20 with chamfers is fixed around the elevator button steel plate through the mounting holes 12. The fine-tuning slide rail 13 is adjusted to a position 2-3 cm above each row of buttons and fixed with the locking screw A14. The horizontal position of the mounting seat 15 on the slide rail 13 is fine-tuned. After reaching above each button, the locking screw B16 is tightened. The angles of the infrared emitter and receiver of the infrared reflection type sensing module 17 are fine-tuned, and the power supply of the control board 18 is turned on. When in use, when a finger approaches the elevator button, the finger reflects the infrared ray to the receiver. The receiver receives the signal and sends it to the input end of the control board 18. The control board 18 sends the signal to the elevator button control unit, and the corresponding button indicator light is lit, and the elevator operates. If the action situation is too close or too far away, the potentiometer on the control board 18 is fine-tuned to change the reaction sensitivity. The initial settings of the products in this application are the general positions and general functions. All the above fine-tuning functions are used when there are errors in on-site applications. The general settings are the default settings for most elevators. After installing the frame and connecting the control board, it can be used. The ultraviolet lamp 19 is controlled by the control board 18 and is started after a certain period of time (such as 5-10 s) after the button action and turned off after 10-30 s.

[0033] Embodiment 2

[0034] This embodiment provides an elevator button auxiliary device. The fixed frame 11 with chamfers is fixed around the elevator button steel plate through the mounting holes 12. The fine-tuning slide rail 13 is adjusted to a position 2-3 cm to the left or right of each column of buttons and fixed with the locking screw A14. The vertical position of the mounting seat 15 on the slide rail 13 is fine-tuned. After reaching the left side of each button, the locking screw B16 is tightened. The angles of the infrared emitter and receiver of the infrared reflection type sensing module 17 are fine-tuned, and the power supply of the control board 18 is turned on. When a finger approaches the elevator button, the corresponding button indicator light on the control board lights up. The fine-tuning function of this embodiment is also the default setting and does not need to be adjusted, and is only used when there are errors in the actual site.

[0035] Fixed frame 20: The fixed frame 20 is fixed on the two side steel plates of the elevator button, and the slide rail 13 is installed at intervals in the middle. The slide rail 13 has an adjustable mounting pitch. The frame is provided with a U-shaped structure, and there are installation positions for the ultraviolet lamp 19 and the control board 18.

[0036] Ultraviolet lamp 19: The ultraviolet lamp 19 is fixed on one side of the frame, and the irradiation area is the elevator button area.

[0037] Mounting seat 15: The mounting seat 15 is fixed on the slide rail 13, and there is a locking screw A14 on it, which is used in cooperation with the pitch of the slide rail 13 and can adjust the mounting position arbitrarily. There is also an adjusting screw for adjusting and fixing the infrared emitter and receiver.

[0038] Infrared emission and reception sensor: The infrared emission and reception sensor includes a transmitting head and a receiving head, which are fixed on the mounting base 15, fixed unilaterally for the button, with adjustable position and forming a certain angle with each other (such as 35 degrees). Each module corresponds to a button, and the module sends signals to the control board 18 through a dedicated cable.

[0039] Control board 18: The control board 18 controls the infrared transmitting head to emit infrared rays. When a finger approaches the button, the finger reflects the infrared rays to the receiving head. The receiving head receives the signal and sends it to the input end of the control board 18. The control board 18 sends the signal to the elevator button control unit, and the corresponding button lights up, and the elevator operates. The control board 18 has a design with adjustable power and sensitivity. According to different button arrangement structures, different sensitivities are selected. The chip model of the control board is preferably LM339.

[0040] As Figure 3 shown, it is the principle of a detection circuit. VR1 is a potentiometer that can adjust the sensitivity of the circuit detection. The adjusted voltage is input to the inverting input terminal "-" of the operational amplifier. The voltage at the non-inverting input terminal "+" of the operational amplifier is controlled by the infrared receiver. When the signal emitted by the infrared transmitting head is blocked by a finger and reflected to the receiving head, the output signal of the receiving head will change, causing the signal at the non-inverting input terminal "+" of the operational amplifier to change. The operational amplifier outputs a low level, the LED indicator lights up, and the signal is sent to the elevator button unit to realize the action of pressing a button. If there is no finger blocking, the receiving head has no signal, the operational amplifier outputs a high level, the LED light goes out, and there is no control signal sent to the elevator button unit.

[0041] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
