The material of the housing body includes, but is not limited to, plastic, lightweight metal, or alloy. In some embodiments, the material of the housing body is plastic, which has a low density and a low cost, so that the weight of the housing 51 can be reduced, and the cost of the housing 51 can be reduced.

The ultraviolet reflection layer may be disposed on a partial region of the inner surface of the housing body, or may be disposed on the entire region of the inner surface of the housing body, which is not specifically limited herein. The larger the setting area of the ultraviolet reflection layer on the inner surface of the shell body is, the higher the reflectivity of ultraviolet light is.

The ultraviolet reflecting layer may be a microprism reflecting film attached to the inner surface of the housing body, or may be a layer of ultraviolet reflecting material formed on the inner surface of the housing body by electroplating, chemical deposition, secondary injection molding, and other processes, and the ultraviolet reflecting material includes, but is not limited to, an aluminum material, an aluminum alloy material, and Polytetrafluoroethylene (PTFE), and is not limited specifically herein.

It is understood that the material of the housing body may also be the same as the material of the uv reflecting layer, and the housing body and the uv reflecting layer are integrally formed. Thus, the housing 51 has a simple structure and is easy to manufacture.

A cavity 53 is arranged in the shell 51, the ultraviolet reflecting layer of the shell 51 forms the inner surface of the cavity 53, an inlet 100 and an outlet 200 are arranged on the shell 51, and the inlet 100 and the outlet 200 are both communicated with the cavity 53. The object to be sterilized enters the cavity 53 through the inlet 100, and is sterilized in the cavity 53, and the object to be sterilized after the sterilization is discharged out of the cavity 53 through the outlet 200.

As shown in fig. 6, the sterilization and disinfection apparatus 5 further includes an ultraviolet light source 52. Optionally, the ultraviolet light source 52 is a C-band ultraviolet light-emitting diode (UVC-LED), and the wavelength of ultraviolet light emitted by the UVC-LED is 200nm to 280nm, which can be used for disinfection and sterilization. The ultraviolet light source 52 is used for emitting ultraviolet light (i.e., UVC) having a sterilizing effect into the cavity 53.

Thus, when the sterilization and disinfection apparatus is applied to a device having a sterilization and disinfection function, such as a mask shown in fig. 4, after an object to be sterilized (such as air) enters the cavity 53 through the inlet 100, part of the ultraviolet light is irradiated by the ultraviolet light emitted from the ultraviolet light source 52 and absorbed by the object to be sterilized to kill viruses and bacteria carried in the object to be sterilized, and part of the ultraviolet light not absorbed by the object to be sterilized is irradiated to the inner surface of the cavity 53 and reflected by the ultraviolet light reflection layer forming the inner surface of the cavity 53, so that the unabsorbed part of the ultraviolet light passes through the object to be sterilized again, thereby performing a second sterilization and disinfection treatment on the object to be sterilized, and if there is part of the ultraviolet light not absorbed by the object to be sterilized during the second sterilization and disinfection treatment, the part of the ultraviolet light can be reflected again by the ultraviolet light reflection layer forming the inner surface of the cavity, the third sterilization and disinfection treatment is carried out on the object to be sterilized, so that the repeated sterilization and disinfection treatment is carried out on the object to be sterilized in sequence until all ultraviolet light is absorbed by the object to be sterilized, and the utilization rate of the ultraviolet light can be improved. Meanwhile, the ultraviolet light has a high propagation speed, and can be used for carrying out multiple sterilization and disinfection treatments on solid objects to be sterilized which are statically arranged in the cavity or liquid or gas objects to be sterilized flowing through the cavity, so that the sterilization and disinfection efficiency is high.

In order to improve the sterilization uniformity of the sterilization device 5, in some embodiments, the sterilization device 5 further comprises at least one first partition. The at least one first partition is disposed in the cavity 53, and the cavity 53 is divided into a plurality of independent cavity units by the at least one first partition.

The number of the chamber units into which the chamber 53 is divided by the first partition plate may be two, three, four, etc., and is not particularly limited herein.

Illustratively, as shown in fig. 6, the sterilization and disinfection apparatus 5 includes two first partitions 54 perpendicular to each other, and the two first partitions 54 divide the chamber 53 into four chamber units independent from each other, namely a chamber unit 53a, a chamber unit 53b, a chamber unit 53c, and a chamber unit 53 d.

The number of the inlets 100 is plural, and each of the plural cavity units is respectively communicated with one or more inlets 100. Thus, the object to be sterilized can be dispersed into the plurality of chamber units through the plurality of inlets 100.

In the above embodiment, each of the plurality of cavity units may be respectively communicated with one inlet 100, or respectively communicated with a plurality of inlets 100, which is not limited herein. Fig. 6 only shows an example in which each of the plurality of chamber units communicates with one inlet 100, respectively, and is not to be construed as limiting the present application.

The number of the ultraviolet light sources 52 is plural, and each of the plural cavity units corresponds to one or more ultraviolet light sources 52. It can be known that the chamber unit corresponds to the ultraviolet light source 52, that is, the ultraviolet light source 52 emits the ultraviolet light with sterilization and disinfection effects into the chamber unit, in other words, the ultraviolet light source 52 corresponding to the chamber unit is used for emitting the ultraviolet light with sterilization and disinfection effects into the chamber unit. In this way, the ultraviolet light sources 52 can respectively sterilize and disinfect the objects to be sterilized in the cavity units, thereby improving the sterilization uniformity of the objects to be sterilized.

In the above embodiment, each of the plurality of cavity units may correspond to one ultraviolet light source 52, or correspond to a plurality of ultraviolet light sources 52, which is not limited herein. Fig. 6 only shows an example in which each of the plurality of cavity units corresponds to two uv light sources 52, and should not be construed as limiting the present application.

The number of the outlets 200 is plural, and each of the plural cavity units is respectively communicated with one or more outlets 200. Thus, the objects to be sterilized in the plurality of chamber units after sterilization and disinfection can be discharged through the plurality of outlets 200.

In the above embodiment, each of the plurality of cavity units may be respectively communicated with one outlet 200, or respectively communicated with a plurality of outlets 200, which is not limited herein. Fig. 6 only shows an example in which each of the plurality of chamber units is respectively communicated with one outlet 200, and is not to be construed as limiting the present application.

When the object to be sterilized is a fluid, the object to be sterilized flows into the chamber 53 through the inlet 100 and flows out through the outlet 200, in order to prolong the flowing time of the object to be sterilized in the chamber 53, so that the object to be sterilized can be fully contacted with the ultraviolet light emitted by the ultraviolet light source 52, in some embodiments, as shown in fig. 6, the sterilization and disinfection apparatus 5 further includes a plurality of second partition plates 55, and one or more second partition plates 55 are respectively disposed in each of the plurality of chamber units. Fig. 8 is a front view of the sterilization and disinfection apparatus shown in fig. 6, and as shown in fig. 8, the second partition 55 can extend a passage path from the inlet 100 to the outlet 200 in the chamber unit. Thus, the time for the object to be sterilized to flow in the cavity 53 is longer, and the sterilization and disinfection efficiency is higher.

In the above embodiment, each of the plurality of cavity units may be provided with one second partition plate 55, or may be provided with a plurality of second partition plates 55, which is not limited herein. Fig. 6 shows only an example in which one second partition 55 is provided in each of the plurality of chamber units, and is not to be construed as limiting the present application.

It should be noted that the second partition 55 extends the path of the passage from the inlet 100 to the outlet 200 in the chamber unit, that is, the second partition 55 is located in the straight path from the inlet 100 to the outlet 200 in the chamber unit, the object to be sterilized flowing into the chamber 53 from the inlet 100 needs to bypass the second partition 55 before being discharged from the outlet 200, and the length of the flow path from the inlet 100 to the outlet 200 of the object to be sterilized in the chamber unit is longer than the length of the straight path from the inlet 100 to the outlet 200. The second partition 55 may be perpendicular to the straight path from the inlet 100 to the outlet 200, or may form an included angle with the straight path from the inlet 100 to the outlet 200, the included angle is smaller than 90 °, and the included angle is not particularly limited as long as the object to be sterilized flowing from the inlet 100 into the cavity 53 needs to bypass the second partition 55 to be discharged from the outlet 200.

In order to further improve the sterilization efficiency of the sterilization device 5, in some embodiments, as shown in fig. 8, the number of the uv light sources 52 corresponding to the chamber unit is plural, and the plural uv light sources 52 are sequentially arranged along the extending direction of the channel path from the inlet 100 to the outlet 200 in the chamber unit. In this way, the object to be sterilized flowing in the chamber unit can be sterilized for a plurality of times by the plurality of ultraviolet light sources 52, and therefore, the sterilization efficiency of the sterilization and disinfection apparatus 5 can be further improved.

In the above embodiment, the number of the ultraviolet light sources 52 corresponding to each cavity unit may be two, three, four, and the like, and is not limited in detail. The larger the number of ultraviolet light sources 52, the higher the sterilization and disinfection efficiency, and accordingly, the larger the amount of heat generated by the sterilization and disinfection apparatus 5 during operation, the greater the discomfort given to the mouth of the wearer when the sterilization and disinfection apparatus 5 is applied to a mask. To avoid this problem, in some embodiments, as shown in fig. 6 and 8, the number of the ultraviolet light sources 52 corresponding to each chamber unit is two, so that the number of the ultraviolet light sources 52 corresponding to each chamber unit is moderate, and the sterilization efficiency and the heat generation amount can be considered at the same time.

The first partition plate 54 and the second partition plate 55 may be plastic plates, light metal plates, or alloy plates, etc., on the surfaces of which the ultraviolet reflection layer is disposed, and the first partition plate 54 and the second partition plate 55 may also be transparent plates, which is not particularly limited herein.

In some embodiments, the first and

second partitions

54, 55 are both light-transmissive plates. Therefore, ultraviolet light in the cavity units can mutually permeate, and the utilization rate of the ultraviolet light can be improved.

The housing 51 may be a single structural member or a plurality of structural members that can be detached, and is not particularly limited herein.

In some embodiments, as shown in FIG. 6, the housing 51 includes a base 511 and a cover 512. The base 511 comprises a bottom plate and side plates arranged at the edge of the bottom plate, the bottom plate and the side plates enclose a cavity 53, and one end of the cavity 53, which is far away from the bottom plate, is opened. The cover plate 512 covers an opening at one end of the cavity 53 far away from the bottom plate, and the cover plate 512 is detachably connected with the base 511. Thus, the housing 51 is formed by detachably connecting a plurality of structural members, which facilitates the processing and manufacturing of the housing 51.

In the above embodiment, alternatively, as shown in fig. 6, the first partition plate 54 and the second partition plate 55 are fixed in the pedestal 512. Fig. 7 is an exploded view of the sterilization and disinfection apparatus shown in fig. 6 in another orientation, as shown in fig. 7, a first recess 512a and a second recess 512b are formed on the inner surface of the cover plate 512, one end of the first partition plate 54 close to the cover plate 512 is fitted to extend into the first recess 512a, and one end of the second partition plate 55 close to the cover plate 512 is fitted to extend into the second recess 512 b. In this way, gaps between the first partition plate 54 and the cover plate 512 and between the second partition plate 55 and the cover plate 512 can be avoided, thereby ensuring independence between the plurality of chamber units partitioned by the first partition plate 54.

In the above embodiments, the inner surface of the cover plate 512 refers to the surface of the cover plate 512 facing the cavity 53.

The inlet 100 and the outlet 200 may be disposed on two opposite walls of the housing 51, may be disposed on two adjacent walls of the housing 51, and may be disposed on the same wall of the housing 51, which is not particularly limited herein.
