The spread of germs and can reduce the time a single pair of shoes is used for disinfection. Optionally, the cabinet 10 may also include one or more larger spaces, so as to sterilize multiple pairs of shoes at the same time, and save the time for sterilizing all shoes and the resources that need to be consumed.

Optionally, the cabinet door 20 can be rotatably connected to the cabinet body 10 along the vertical side of the cabinet body 10, and can also be rotatably connected to the cabinet body 10 along other sides of the cabinet body 10. Optionally, the cabinet door 20 can also be It is slidably connected to the cabinet body 10 to reduce the space occupied when the shoe cabinet is opened.

Ultraviolet LED (UV LED) arrays 30 are disposed on the inner surface of the cabinet body 10 or the inner surface of the cabinet door 20. Specifically, the number of UV LED arrays 30 corresponding to each compartment can be one or more , which is used for emitting ultraviolet rays to sterilize the shoes accommodated in the cabinet 10 . Specifically, it can be concentrated in the position where the emitted ultraviolet rays can be irradiated to the sole of the shoe, and at the same time, it can be irradiated to all the positions in the compartment where the shoes have been placed in the shoe cabinet as much as possible. The ground is in contact with the ground, so it is necessary to focus on sterilizing the sole to improve the efficiency of sterilization. Optionally, the sterilizing shoe cabinet may also include some compartments without the ultraviolet light emitting diode array 30, so as to store shoes that have been sterilized or do not need to be sterilized. Ultraviolet rays can destroy the molecular structure of bacteria, virus deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) remaining on shoes, thus completely killing germs and inhibiting their reproduction again. All bacteria, viruses and other harmful microorganisms have a strong killing effect, and as a physical germ killing method, it is relatively safe and reliable.

In a preferred embodiment, the baffle supporting the sole can be made of a transparent material, for example, such as glass or a transparent plastic plate. The surface emits UV light to disinfect the sole.

At the same time, the disinfection shoe cabinet can also determine whether ultraviolet disinfection is required by sensing whether there are shoes in it, thereby reducing ultraviolet radiation and saving resources.

Optionally, the contact switch 40 is further configured to turn off the sterilization starting signal after a preset period of time has elapsed after the sterilization starting signal is generated. Specifically, when the contact switch 40 senses that the cabinet door 20 is closed, a sterilization start signal with a preset duration can be generated, so that the drive circuit can control the ultraviolet LED array 30 to perform ultraviolet disinfection with a preset duration. Exemplarily, the preset time period may be 15 minutes, so as to avoid waste of resources caused by turning on the ultraviolet light emitting diode array 30 for a long time on the basis of ensuring the disinfection effect.

Optionally, the contact switch 40 is also used to turn off the disinfection start signal when it is sensed that the cabinet door 20 is opened. When the contact switch 40 senses the opening of the cabinet door 20, it can no longer generate a disinfection start signal, so as to control the driving circuit to no longer generate a driving voltage, so that the ultraviolet light emitting diode array 30 stops emitting ultraviolet rays, so as to ensure that people need to use shoes to avoid When the shoes are taken out from the shoe cabinet, they will not be damaged by the ultraviolet rays emitted by the ultraviolet light emitting diode array 30 .

On the basis of the above technical solution, optionally, the disinfection shoe cabinet further includes: an ultraviolet absorbing layer, the ultraviolet absorbing layer is arranged on the inner wall of the cabinet body 10, and is arranged on the outer side of the ultraviolet light emitting diode array 30 for absorbing the ultraviolet light emitting diodes UV light from array 30.

Specifically, the ultraviolet absorbing layer can fill the inner wall of the cabinet 10 to prevent excessive ultraviolet rays from seeping out from any angle, thereby causing ultraviolet damage to nearby human bodies or living beings. Further, the inner wall of the cabinet door 20 can also be filled, so as to completely wrap the shoe cabinet. Optionally, the ultraviolet absorbing layer includes an ultraviolet absorbing agent and a non-woven fabric, and can be formed by compounding the ultraviolet absorbing agent and the non-woven fabric. Wherein, the ultraviolet absorbing layer can be one or more of salicylates, benzophenones, benzotriazoles, substituted acrylonitriles and triazines.
