Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of ultraviolet disinfection, and particularly relates to an ultraviolet disinfection device. BACKGROUND

[0002] In the prior art, ultraviolet sterilization products are usually single-function, and to meet the two needs of sterilizing personal objects and indoor air, users can only purchase products with separate functions, and the disinfection process is relatively single, and there is a situation of insufficient disinfection. For example, a contrast document 1 with an authorized publication number of CN202161601U discloses a mobile ultraviolet air sterilizer, which proposes to set an air outlet at the upper end of the sterilizer shell, set an air inlet at the lower end, install a direct current fan at the air inlet, and set an ultraviolet lamp in the shell. In the process of driving air to enter the shell from the air inlet and flow out from the air outlet by the direct current fan, the air is sterilized by the ultraviolet lamp. The contrast document 1 can only sterilize air, and the flow time of air from the air inlet to the air outlet is limited by the air flow rate and the distance between the air inlet and the air outlet, so that the time of air under ultraviolet irradiation is short, and the sterilization is not sufficient. For another example, a contrast document 2 with an authorized publication number of CN208877385U discloses an ultraviolet sterilization and disinfection tableware box, which sterilizes and disinfects tableware in the ultraviolet sterilization and disinfection tableware box by an ultraviolet lamp, and sets air vents and air inlets on the base and the diffuse reflection shell respectively, forms air convection in the diffuse reflection shell, and facilitates the rapid drying of the sterilized tableware. However, dust, bacteria and the like exist in external air, which enters the ultraviolet sterilization and disinfection tableware box through the air vents or the air inlets, and there is a situation of secondary pollution.

DETAILED DESCRIPTION

[0047] To make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application and their beneficial effects will be described in further detail below with reference to the drawings.

[0048] Reference is made to Figure 1 and Figure 2 The embodiments of the present application provide an ultraviolet sterilizer, which is defined as:

[0049] The ultraviolet sterilizer comprises a housing assembly 1 and an ultraviolet assembly 2. The housing assembly 1 comprises a first housing 12 and a second housing 14. The first housing 12 and the second housing 14 are hingedly connected to each other, so that the first housing 12 can rotate relative to the second housing 14 about the hinge point to open or close the sterilization cavity 18, so as to put the sterilized articles into the sterilization cavity 18 or take the sterilized articles out of the sterilization cavity 18. A first air vent 110 is arranged on the first housing 12 or the second housing 14, so that the air in the sterilization cavity 18 can flow out through the first air vent 110, or the air outside can flow into the sterilization cavity 18 through the first air vent 110. The ultraviolet assembly 2 comprises an ultraviolet lamp placement tube 22 and an ultraviolet lamp 24. Specifically, the ultraviolet lamp placement tube 22 is internally provided with an air passage 228 for air flow. The ultraviolet lamp 24 is placed in the air passage 228. The ultraviolet assembly 2 is airtight. The ultraviolet light emitted by the ultraviolet lamp 24 can pass through the tube wall of the ultraviolet lamp placement tube 22 and enter the sterilization cavity 18, so as to sterilize the articles to be sterilized placed in the sterilization cavity 18 and the air in the sterilization cavity. One end of the air passage 228 is communicated with the sterilization cavity 18 through an air vent 114 arranged on the second housing 14. The other end of the air passage 228 is communicated with the atmosphere outside through a second air vent 112 arranged on the first housing 12 or the second housing 14. An air pump 26 is arranged in the air passage 228. The air pump 26 drives the air in the air passage 228 to flow from one end of the air passage 228 to the other end of the air passage 228, for example, the air flow direction is Figure 2The air in the air passage 228 is sterilized by the ultraviolet light emitted by the ultraviolet lamp 24, and after entering the sterilization cavity 18, the air is sterilized again by the ultraviolet light emitted through the wall of the ultraviolet lamp placement tube 22, and then discharged from the sterilization cavity 18 through the first air vent 110, so that the air in the air passage 228 and the sterilization cavity 18 is sterilized under the irradiation of ultraviolet light, realizing the circulating sterilization of indoor air. It should be noted that after the air is sterilized in the air passage 228, it enters the sterilization cavity 18 to avoid the active bacteria and viruses in the external air from entering the sterilization cavity 18 and causing secondary pollution to the sterilization objects in the sterilization cavity 18. It should be further noted that after the air flows into the sterilization cavity 18, the flow rate of the air decreases due to the relatively large space in the sterilization cavity 18, and the air can stay in the sterilization cavity 18 for a long time, which is beneficial to the more sufficient sterilization of the air by the ultraviolet light and improves the sterilization effect. It should be emphasized that if the sterilization objects in the sterilization cavity 18 are wet dishes, clothes and the like, the evaporation of water can be accelerated by the flow of air in the sterilization cavity 18, so that the sterilized objects can be quickly dried. Alternatively, the air pump 26 can also make the external air first enter the sterilization cavity 18 through the first air vent 110 and then flow out through the air passage 228, so as to avoid the bacteria and viruses on the sterilization objects being blown up and flowing into the external air in the case that the sterilization objects are not completely sterilized when the air flows through the sterilization objects in the sterilization cavity 18, thereby causing pollution of the indoor air.

[0050] It can be understood that another ultraviolet assembly 2 can also be added, one end of the air passage 228 of the other ultraviolet assembly 2 is in communication with the first air vent 110 on the second shell 14, and the other end is in communication with the external atmosphere, so that the external air is sterilized by the sterilization lamp in the air passage 228 when entering the sterilization cavity 18 or the air in the sterilization cavity 18 flows to the outside, so as to further improve the sterilization effect and avoid mutual pollution of the external air and the sterilization objects in the sterilization cavity 18.

[0051] As shown in Figure 1 Optionally, the ultraviolet lamp placement tube 22 is arranged at the bottom and / or side and / or top of the inner wall of the second shell 14.

[0052] The ultraviolet light irradiance is the largest in the area close to the ultraviolet lamp tube, and the sterilization efficiency is the highest; after the air flows through all the ultraviolet assemblies 2, the air is discharged through the sterilization cavity 18, so that the air is irradiated by ultraviolet light again when passing through the sterilization cavity 18; wherein the ultraviolet lamp 24 can be but is not limited to a mercury lamp tube, an ultraviolet LED, a deep ultraviolet LED and the like.

[0053] As shown in Figure 1 andFigure 7 As shown, the hinge point of the first shell 12 and the second shell 14 can be on the side of the first shell 12 and the second shell 14 or on the top, so that the first shell 12 and the second shell 14 can be different structures such as diagonal opening, front opening, up-down flip cover, etc.

[0054] It should be emphasized that the ultraviolet sterilizer provided by the present application can not only sterilize articles but also circulate and sterilize indoor air, so the application is more extensive.

[0055] It should be noted that the first vent hole 110 and the second vent hole 112 can be arranged at any position on the first shell 12 or the second shell 14 according to actual needs.

[0056] Preferably, the first vent hole 110 is arranged at the top of the first shell 12 or the second shell 14, and the vent 114 is arranged at the bottom of the second shell 14, so that the air flows into the sterilization cavity 18 from the vent 114 at the bottom of the second shell 14 and flows out from the first vent hole 110 arranged at the top of the first shell 12 or the second shell 14, so that the flow distance of the air in the sterilization cavity 18 is large, the residence time of the air in the sterilization cavity 18 is increased, and the air sterilization effect is improved.

[0057] As shown in the embodiment of the present application, it is further limited that: Figure 1 A second reflective layer 16 for reflecting ultraviolet rays is arranged on the inner wall of the first shell 12, so that the ultraviolet rays emitted by the ultraviolet lamp 24 are reflected by the second reflective layer 16 and re-enter the sterilization cavity 18, which on the one hand increases the intensity of the ultraviolet rays in the sterilization cavity 18, and on the other hand increases the angle of the ultraviolet rays in the sterilization cavity 18, reduces the dead angle of the ultraviolet rays, and improves the sterilization effect on the articles to be sterilized.

[0058] Or a second reflective layer 16 for reflecting ultraviolet rays is arranged on the inner wall of the second shell 14, so that the ultraviolet rays emitted by the ultraviolet lamp 24 are reflected by the second reflective layer 16 and re-enter the sterilization cavity 18, and the ultraviolet light is reflected multiple times in the sterilization cavity 18, which improves the utilization rate of the ultraviolet light and increases the coverage range of the ultraviolet light, on the one hand increases the intensity of the ultraviolet rays in the sterilization cavity 18, and on the other hand increases the angle of the ultraviolet rays in the sterilization cavity 18, reduces the dead angle of the ultraviolet rays, and improves the sterilization effect on the articles to be sterilized.

[0059]

[0060] ​Alternatively, a second reflective layer 16 for reflecting ultraviolet rays can be provided on the inner walls of the first housing 12 and the second housing 14, so that the ultraviolet rays emitted by the ultraviolet lamp 24 can be reflected back into the disinfection chamber 18 under the reflection of the second reflective layer 16. On the one hand, this increases the intensity of ultraviolet irradiation in the disinfection chamber 18, and on the other hand, it increases the irradiation angle of ultraviolet rays in the disinfection chamber 18, reduces the dead angle of ultraviolet irradiation, and improves the disinfection effect of the items to be disinfected.

[0061] The material of the second reflective layer 16 may be, but is not limited to, Teflon, stainless steel, aluminum, aluminized plastic, silicon dioxide, calcium sulfate, etc. Materials that reflect ultraviolet light, such as reflective materials, can also be photocatalytic coatings.

[0066] In one specific embodiment, the turntable 4 is made of quartz glass, which has a high ultraviolet transmittance. Ultraviolet light from the bottom of the sterilizer can penetrate the quartz glass turntable 4 to sterilize the bottom of the objects on it. Optionally, the turntable 4 can be made of a plastic material with high ultraviolet transmittance, or, for example, a dark or black glass material that is opaque to visible light but highly transparent to ultraviolet light.
