[0002] Entrance and exit of high-rise buildings all rely on elevators, especially in public places with dense traffic such as office buildings, residential areas, and shopping malls. At present, most elevators reach the required floor by touching the floor buttons, and a large number of bacteria remain on the elevator buttons. At the moment of the outbreak, facilities that are frequently touched by the public, such as door handles and elevator buttons in shared places, may be at risk of cross-infection due to mutual contact, and elevators are confined spaces. During the special period of epidemic prevention and control, plastic wrap, paper towels, and even toothpicks and ballpoint pens have become standard prevention and control equipment in elevators. However, when using these means to press the buttons, these items are touched again, which only treats the symptoms but not the root cause. Cross-infection is still inevitable, so an elevator button control device is needed, but the existing elevator button control devices have many problems or defects:

[0003] It is very difficult to modify the existing elevator button control device in the elevator equipment. At the same time, it is necessary to take out the mobile phone to open the specified interface every time taking the elevator, which will bring great inconvenience to the use and make it difficult for the elderly, children and other people to operate; the existing elevator button control device is usually not adjustable and cannot be adapted to different elevator button spacings; the existing elevator button control device usually does not have a disinfection device, and people who have not used it are prone to touch the device directly with their hands, which may cause cross infection.

[0037] The disinfection mechanism includes a liquid storage tank 17, a partition plate 18, a heating plate 19 and an air jet valve 21. The partition plate 18 is horizontally fixedly connected to the inside of the liquid storage tank 17, the heating plate 19 is fixedly installed on the bottom plate of the liquid storage tank 17, a delivery pipe 20 is sleeved on the top of the liquid storage tank 17, and an air jet valve 21 is sleeved on the delivery pipe 20. Nozzles 22 are fixedly connected on both sides of the air jet valve 21 corresponding to each other, and a liquid filling port 23 is provided on the outer wall of one side of the liquid storage tank 17.

[0038] Specifically, a cross slot 24 is opened on one side plate of the trigger protection shell 8 , and the number of the cross slots 24 is four, and the four cross slots 24 are vertically and equidistantly arranged on the trigger protection shell 8 .

[0039] Specifically, a protective cover 25 is slidably installed in the cross slide groove 24 , and the sensing probe 11 is sleeved in the protective cover 25 to prevent the sensing probe 11 from being worn.

[0040] Specifically, the number of the trigger protection shells 8 is two, and the two main boards 2 are connected by snapping together through a first sliding member 14 and a second sliding member 15 .

[0041] Specifically, the trigger protection shell 8 is fixedly sleeved with a mounting sleeve 26 on a side plate away from the sensing probe 11, and the iron core of the electromagnet 13 is slidably mounted in the mounting sleeve 26 for easy movement.

[0043] Specifically, a honeycomb hole 29 is opened on one side plate of the main controller protection shell 1 , and the position of the honeycomb hole 29 corresponds to the position of the pickup microphone 6 .

[0044] Specifically, four positioning columns 30 are fixedly connected to the inner wall of one side of the main controller protective shell 1. The four positioning columns 30 are respectively located at the four corners inside the main controller protective shell 1.

[0046] Specifically, the number of the jet valves 21 is four, and the four jet valves 21 are vertically and equidistantly arranged in the delivery pipe 20, so that the spraying is more uniform.

[0047] Working principle: The electrical components appearing in this application document are all externally connected to a power source and a control switch when in use. When in use, the two trigger protective shells 8 are snapped together through a first sliding member 14 and a second sliding member 15, and then the main controller protective shell 1 is installed above the two trigger protective shells 8, the liquid storage tank 17 is installed below the two trigger protective shells 8, and the delivery pipe 20 is installed in the gap between the two trigger protective shells 8.

[0048] When voice control is required, the pickup microphone 6 will collect the voice data of the elevator user, and the Raspberry Pi control module 3 will send the voice to the Baidu API for decoding and analysis. If the set keyword appears, the Raspberry Pi control module 3 will send a signal to the Arduino control module 4. The Arduino control module 4 sends a signal through the serial port to control the relay 12 of the corresponding floor to close. When the relay 12 is closed, the electromagnet 13 will be energized, thereby pressing the elevator button. When induction trigger control is required, the finger approaches the infrared photoelectric sensor 10 on the trigger mechanism. When the infrared photoelectric sensor 10 detects the finger approaching, it sends a signal to the Arduino control module 4. The Arduino control module 4 sends a signal through the serial port to control the relay 12 of the corresponding floor to close. When the relay 12 is closed, the electromagnet 13 is energized, thereby pressing the elevator button.

[0049] When used for elevator buttons with different spacings, the vertical spacing of the elevator buttons is adapted by moving the position of the electromagnet 13 up and down, and the horizontal spacing of the elevator buttons is adapted by moving the position of the electromagnet 13 left and right, and then fixed by the mounting plate 16. The position of the mounting frame 9 is also adjustable, which can ensure that the spacing between two adjacent sensing probes 11 is equal, thereby improving the sensing effect and preventing false touches.

[0050] When no one has been riding the elevator for a long time, the Arduino control module 4 will control the heating plate 19 to start, and the heating plate 19 will heat the alcohol in the liquid storage tank 17, and then the alcohol will become alcohol vapor, which will be sprayed out from the nozzle 22 on the jet valve 21 along the delivery pipe 20, and then sprayed on the surface of the trigger protective shell 8 to disinfect it, so as to prevent cross infection caused by touching the trigger protective shell 8.
