[0034] Furthermore, a reflective plate 5 is provided on the inner wall of the top plate of the mask 1 .

[0035] Preferably, the reflector 5 is inclined at an angle such that the intersection of the extension line of the reflector 5 from the outside to the inside and the center line 115 of the elevator button on the surface of the elevator button 9 forms a straight line, as shown by the reflector extension line 112 .

[0036] Furthermore, the center extension line 113 of the LED ultraviolet lamp bead 4 on the LED ultraviolet lamp circuit board 10 is in a straight line with the distal outer edge of the elevator button 9, and the center extension line 113 of the LED ultraviolet lamp bead is 90° with the LED ultraviolet lamp circuit board 10, as shown by the angle 116 between the center extension line of the LED ultraviolet lamp bead and the LED ultraviolet lamp circuit board.

[0037] Preferably, the horizontal line of the bottom of the LED ultraviolet lamp bead 4 on the LED ultraviolet lamp circuit board 10 is not lower than the bottom of the reflector 5, as shown by the horizontal line 111 at the bottom of the LED ultraviolet lamp bead, to ensure that there is no light leakage and avoid harm to the human body.

[0038] Furthermore, an anti-reflective sticker 8 is included, which is pasted on the surface of the front gap of the elevator button 9 to ensure that the ultraviolet light irradiated on the front gap surface of the elevator button 9 will not reflect, avoiding harm to the human body. The anti-reflective sticker 8 is an anti-reflective frosted sticker.

[0039] Furthermore, three LED ultraviolet lamp beads 4 are provided on each LED ultraviolet lamp circuit board 10 .

[0040] Each row of elevator buttons is equipped with at least one LED UV lamp bead, and the corresponding number of modules is configured according to the number of elevator buttons, such as Figure 5 As shown, each row of elevator buttons 9 is equipped with two LED ultraviolet lamp beads, one on the left and one on the right side of each row of elevator buttons, so that the ultraviolet light irradiation is more uniform and the intensity is greater.

[0041] Specifically, the mask 1 is made of 304 stainless steel, and the mask is fixed to the elevator by two screws 3 through its Z-shaped lower bottom surface. The infrared counter-radiation sensing area 114 generated by the infrared counter-radiation sensor 2 covers the front of the elevator button without dead angles. A reflector 5 is installed on the top inner wall of the mask 1 to focus light, and the reflector extension line 112 can cover all elevator buttons 9. An LED ultraviolet lamp circuit board 10 is installed on the side wall of the mask 1. The center extension line 113 of the LED ultraviolet lamp bead 4 extends to the far outside of the elevator button 9 and covers all buttons. The main control circuit board 6 is built-in and installed inside the elevator panel. The LED ultraviolet lamp bead circuit board 10 and the infrared counter-radiation sensor 2 are connected by a connecting line 7 to control the disinfection operation and infrared sensing. Anti-reflective frosted material stickers are pasted on the gap surfaces of each button of the elevator button 9. The anti-reflective frosted material stickers are black anti-reflective frosted material stickers to prevent reflective ultraviolet rays from harming the human body.

[0042] like Figure 4 As shown, the LED ultraviolet lamp beads 4 are welded on the LED ultraviolet lamp bead circuit board 10, and the LED ultraviolet lamp bead circuit board 10 is provided with a connection line connected to the main control circuit board 6. The LED ultraviolet lamp beads 4 are UVC ultraviolet LEDs, and each LED ultraviolet lamp bead circuit board 10 is provided with 3 LED ultraviolet lamp beads 4.

[0043] like Figure 6 As shown, the device is controlled by a main control circuit board 6, which includes an STM8 main controller, an AC-DC module, a step-down module and a switch module. The STM8 main controller is electrically connected to the step-down module and the switch module, the AC-DC module is electrically connected to the step-down module, the infrared radiation sensor 2 is electrically connected to the STM8 main controller, and the LED ultraviolet lamp bead circuit board 10 is electrically connected to the STM8 main controller.

[0044] The working process steps of this device are as follows: the AC to DC module is connected to an AC 220V power supply, outputs a DC 12V, and outputs 5V through the step-down module to power the STM8 main controller. After the infrared radiation sensor 2 senses that someone presses the elevator button, it outputs a signal to the STM8 main controller. After receiving the signal, the STM8 main controller controls the switch module to open, provides power to the LED ultraviolet lamp beads 4 on the LED ultraviolet lamp circuit board 10, and emits ultraviolet light to disinfect the elevator button 9 for 1 minute. During this 1-minute disinfection time period, if someone needs to press the elevator button, when stretching out to press the button, the human hand first enters the infrared radiation sensing area 114, and the infrared radiation sensor 2 detects the human hand and outputs a signal to the STM8 main controller. After receiving the signal, the STM8 main controller controls the switch module to turn off the power supply of the LED ultraviolet lamp circuit board, suspends the disinfection operation, and waits for the human hand to leave the infrared radiation sensing area 114, and then disinfects again for 1 minute. When no one presses the elevator button for a long time, the STM8 main controller issues a disinfection instruction every half an hour.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
