Description

A public button capable of automatic disinfection and sterilization

The invention relates to the technical field of key switches, in particular to a public key capable of automatic disinfection and sterilization.

In public places, due to frequent personnel activities, there are many bacteria and viruses, such as Escherichia coli, Staphylococcus aureus, Proteus and other harmful bacteria; some viruses are more harmful, such as new coronavirus, mumps virus, influenza virus Wait. These viruses and germs will attach to public keys, such as ATM machines, elevators, electric lights, public password doors, public switch doors, public remote controls, keys of public drinking fountains, etc. If the fingers are not cleaned and disinfected in time after touching, people will may be infected with disease. Therefore, places that are easily touched by people in public places should be given the most attention, and the disinfection and sterilization of such areas should be very timely and effective. Although under the attack of the new crown epidemic, the keys in public places are often disinfected, but the effect of disinfection is difficult to guarantee, and it is impossible to disinfect every moment. It is also impossible for the disinfection staff to stand by the button all the time and carry out disinfection work continuously. Therefore, it is very important to invent a public key that can be automatically sterilized.

The purpose of this creation is to provide a public button that can be automatically sterilized and sterilized, so as to solve the problem of disinfection and sterilization of the public button.

The technical solution adopted in this creation to solve its technical problems is:

A public key that can be automatically sterilized and sterilized, comprising a casing, a slider is arranged in the casing, an ultraviolet-transmitting panel is arranged at the opening of the upper end of the slider, a groove is arranged in the slider, and the A first circuit board is arranged in the groove, and several ultraviolet lamp beads are arranged on the position of the first circuit board relative to the UV-transparent panel; a second circuit board is arranged under the slider, and the second Buttons are arranged on the circuit board, and the first circuit board is electrically connected to the second circuit board.

Further, a reflective cup is provided outside the ultraviolet lamp bead.

Further, the first circuit board is also provided with a sensor capable of sensing the approach of a human body, or a sensor is connected outside the key.

Further, the edge of the ultraviolet transparent panel is provided with a chamfered structure.

Further, the lower end of the slider is provided with a raised pressing block, and the button is arranged opposite to the pressing block.

Further, the lower end of the slider is also provided with a limit column, and a spring is sleeved on the limit column.

Beneficial effects of this creation: Using this creation can automatically disinfect and sterilize the public keys, which can automatically kill viruses and germs on the key panel with ultraviolet light, without additional disinfection personnel, and can achieve disinfection while ensuring the intensity of ultraviolet light Best results.

The creation will be described in more detail below in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1, a public key that can be automatically sterilized and sterilized includes a housing 1, a slider 2 is arranged in the housing 1, the slider 2 can slide up and down in the housing 1, and the upper end of the slider 2 is open A UV-transmitting panel 3 is arranged at the place, a groove 21 is arranged in the slider 2, a first circuit board 4 is arranged in the groove 21, and the first circuit board 4 is opposite to the UV-transmitting panel 3 A number of ultraviolet lamp beads 5 are arranged at the position, and one or more LED ultraviolet lamp beads can be used; a second circuit board 8 is arranged under the slider 2, and a button 9 is arranged on the second circuit board 8 , the first circuit board 4 and the second circuit board 8 can be connected by flexible wires.

Further, in order to improve the utilization rate of ultraviolet rays, the ultraviolet-transmitting panel 3 is irradiated by reflecting light to achieve a better sterilization effect, and a reflective cup 6 is arranged outside the ultraviolet lamp bead 5 . One reflective cup 6 can be added to each ultraviolet lamp bead 5 , and one reflective cup 6 can also be shared by multiple ultraviolet lamp beads 5 .

Further, in order to avoid harm to the human body, the first circuit board 4 is also provided with a sensor 7 that can sense the approach of the human body; The lamp bead 5, and then the sensor 7 is connected with the first circuit board 4 or the second circuit board 8. If there are many buttons, one external sensor can be shared to realize simultaneous control. The sensor 7 can use a distance sensor.

Further, the edge of the ultraviolet transparent panel 3 is provided with a chamfered structure. Since the edge of the ultraviolet transparent panel 3 is difficult to be irradiated by ultraviolet rays, the edge of the upper surface of the ultraviolet transparent panel 3 is chamfered to reduce the size of the edge and improve the sterilization effect.

Further, in order to better cooperate with the pressing of the button 9 , a raised pressing block 22 is provided at the lower end of the slider 2 , and the button 9 is arranged opposite to the pressing block 22 .

Further, in order to allow the slider 2 to rebound automatically, the lower end of the slider 2 is also provided with a limit post 23 , and the spring 10 is sleeved on the limit post 23 .

The material used for the UV-transmitting panel 3 in this creation must be able to transmit ultraviolet rays to the maximum extent, and acrylic materials, PC materials, UV-transmitting quartz, and UV-transmitting glass can be used; because the transmission efficiency of ultraviolet rays in the air is very low, it is easy to Absorbed by the air, when the intensity of ultraviolet radiation is sufficient, the distance between the ultraviolet lamp bead 5 and the ultraviolet-transmitting panel 3 can be reduced as much as possible, which can reduce the amount of LED ultraviolet lamp beads and greatly reduce the cost; when the sensor 7 detects When the human body approaches, it automatically disconnects the circuit and turns off the ultraviolet light to avoid harm to the human body; if the sensor 7 does not detect the presence of someone, immediately turn on the ultraviolet light for sterilization; of course, the LED can also be controlled according to the distance of the detection of the human body The emission intensity of the UV lamp bead.

The above is an exemplary description of this creation in conjunction with the accompanying drawings. Obviously, the specific implementation of this creation is not limited by the above-mentioned methods, as long as the various improvements of the method concept and technical solution of this creation are adopted, or it is directly applied to other occasions without improvement. All fall within the scope of protection of this creation.
