[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0035] Embodiment 1:

[0036] like Figures 1 to 4 and Fig. 9 As shown, an ultraviolet disinfection cabinet provided by Example 1 of the utility model includes a first shell 1, a plurality of UV irradiation components 2 and two reflective inner tanks 3; all UV irradiation components 2 are arranged in the first shell 1; the UV irradiation components 2 are distributed on each side of the first shell 1; the ultraviolet rays emitted by the UV irradiation components 2 are all directed toward the middle part of the first shell 1; the reflective inner tank 3 is arranged in the first shell 1; the reflective inner tank 3 is fixed to the first shell 1; the two reflective inner tanks 3 are symmetrically covered on the front and rear sides of the first shell 1; the reflective inner tank 3 is provided with an opening 31 for the UV irradiation component 2 to emit ultraviolet light; the ultraviolet light of the UV irradiation component 2 can be emitted to the middle part of the first shell 1 through the opening 31.

[0037] When using the ultraviolet disinfection cabinet provided in Example 1 of the utility model, the object to be disinfected is placed in the center of the interior of the first shell 1, and the UV irradiation component 2 emits ultraviolet light to the middle part of the first shell 1. Most of the ultraviolet light directly irradiates and acts on the object, and some of the ultraviolet light that does not directly act on the object is reflected by two reflective liners 3 covering the front and rear sides of the first shell 1. The reflected ultraviolet light can be refracted on the object to disinfect the object.

[0038] The ultraviolet disinfection cabinet provided by Example 1 of the utility model comprises a first shell 1, a plurality of UV irradiation components 2 and two reflective inner tanks 3; the UV irradiation components 2 are distributed on each side of the first shell 1, and the ultraviolet rays emitted by the UV irradiation components 2 are all directed toward the middle part of the first shell 1. The UV irradiation components 2 provide ultraviolet light irradiation for objects from each side of the first shell 1. Compared with the prior art in which only a rotating ultraviolet lamp bead rod is arranged at the bottom of the fuselage, the ultraviolet disinfection ability of the top and surrounding of the object is improved;

[0039] At the same time, in order to further improve the ultraviolet disinfection ability, two reflective liners 3 are symmetrically covered on the front and rear sides of the first shell 1. The reflective liners 3 are provided with openings 31 for the UV irradiation component 2 to emit ultraviolet light. The ultraviolet light of the UV irradiation component 2 can be emitted to the middle part of the first shell 1 through the openings 31. The reflective liners 3 can reflect the ultraviolet light emitted by the UV irradiation component 2 on the opposite side, and reflect the residual light irradiated on the opposite side to the surface of the object close to the side of the reflective liners 3, thereby enhancing the ultraviolet disinfection effect; similarly, the residual light of the UV irradiation component 2 from the upper side, lower side, left side and right side of the first shell 1 can also be reflected by the reflective liners 3 and act on the object, thereby enhancing the ultraviolet disinfection effect; the residual light here refers to the ultraviolet light that does not directly act on the object;

[0040] In order to make the reflective inner liner 3 resist the impact of external force, the two reflective inner liner 3 are covered on the front and rear sides of the first shell 1. Since the first shell 1 is not easy to bend, the reflective inner liner 3 covered on the front and rear sides of the first shell 1 can avoid bending deformation due to external force, thereby avoiding the reflection of ultraviolet light by the reflective inner liner 3, thereby extending the service life of the ultraviolet disinfection cabinet.

[0041] like Figure 1 and Figures 5-6 As shown, the ultraviolet disinfection cabinet provided by Example 1 of the utility model is preferably provided with a first air inlet 11 and a first air outlet 12 on the first shell 1 in order to air-dry the objects to be disinfected. The first air inlet 11 and the first air outlet 12 are both provided on the rear side of the first shell 1, and the first air inlet 11 is located below the first air outlet 12; a second air inlet 32 ​​and a second air outlet 33 are provided on the reflective liner 3 fixed on the rear side of the first shell 1, the second air inlet 32 ​​is communicated with the first air inlet 11, and the second air outlet 33 is communicated with the first air outlet 12, so that air can enter and flow out from the rear side of the first shell 1 through the reflective liner 3; when the air enters the interior of the first shell 1 from the reflective liner 3, it can be promptly disinfected by ultraviolet rays, and more ultraviolet rays are reflected near the reflective liner 3, which can have a good disinfecting effect on the air and reduce the influence of the disinfecting effect of external air on the objects.

[0042] In order to allow objects to be dried quickly, it is necessary to maintain a stable air intake speed. For this purpose, the ultraviolet disinfection cabinet also includes a fan 4 and an air duct 5 for limiting the wind direction. The fan 4 and the air duct 5 are both arranged outside the first shell 1, and the outlet of the air duct 5 is connected to the first air inlet 11, and the inlet of the air duct 5 is connected to the air outlet of the fan 4. The air duct 5 can isolate the first air inlet 11 from the external airflow to prevent the external airflow from affecting the air intake flow rate. At the same time, the wind blown by the fan 4 can directly enter the air duct 5. The air duct 5 can ensure the flow direction and flow rate of the wind blown by the fan 4, so that the air intake speed of the first air inlet 11 remains stable.

[0043] like Figure 3 and Figures 5-6 As shown, the ultraviolet disinfection cabinet provided in Example 1 of the utility model is preferably provided with a PTC heating device 45 at the connection point between the inlet of the air duct 5 and the outlet of the fan 4 in order to further improve the air drying efficiency of the objects. The PTC heating device 45 can increase the inlet air temperature, thereby achieving the effect of drying the objects; at the same time, when the PTC heating device 45 increases the inlet air temperature, high temperature can be used to assist ultraviolet disinfection, thereby improving the disinfection efficiency of the ultraviolet disinfection cabinet.

[0044] The ultraviolet disinfection cabinet provided in Example 1 of the utility model is preferably further provided with a negative ion generator in the air duct 5. When the fan 4 is blowing and the PTC heating device 45 is not in working state, the negative ion generator releases electrons, and the electrons combine with oxygen atoms in the air to generate negative air ions. The negative air ions enter the ultraviolet disinfection cabinet from the first air inlet 11 through the second air inlet 32. The negative air ions can absorb the odor in the first shell 1 and be discharged from the first air outlet 12 through the second air outlet 33, thereby removing the odor in the ultraviolet disinfection cabinet.

[0045] like Fig. 9 As shown, the ultraviolet disinfection cabinet provided in Example 1 of the utility model is preferably, in order to facilitate the placement of objects to be disinfected into the first shell 1, the front side of the first shell 1 is detachably fixed to the first shell 1, the left end of the front side of the first shell 1 is rotatably connected to the right end of the left side of the first shell 1, and the left end of the front side of the first shell 1 is hinged to the right end of the left side of the first shell 1, so that the first shell 1 can be closed or opened by rotating the front side of the first shell 1.

[0046] like Figures 6-7As shown, the ultraviolet disinfection cabinet provided in Example 1 of the utility model is preferably provided with a second shell 6 in order to protect the first shell 1 and the fan 4 and the air duct 5 outside the first shell 1 and extend the service life of the ultraviolet disinfection cabinet. The second shell 6 is coated on the outside of the first shell 1, and the fan 4 and the air duct 5 are both inside the second shell 6; at the same time, the second shell 6 also strengthens the protection of the reflective liner 3 inside the first shell 1, improves the ability of the ultraviolet disinfection cabinet to resist external force impact, and avoids the deformation of the reflective liner 3 inside the first shell 1 due to external force impact;

[0047] Furthermore, in order to solve the problem of air circulation between the inside of the first shell 1 and the outside air, a third air inlet 61 and a third air outlet 62 are provided on the second shell 6, and the third air outlet 62 is connected with the first air outlet 12. At this time, the outside air can enter the second shell 6 from the third air inlet 61, and the fan 4 sends the outside air into the first shell 1. The third air outlet 62 isolates the outside air. The third air outlet 62 is only connected with the first air outlet 12, that is, the outside air cannot enter the first shell 1 from the first air outlet 12, which reduces the interference of the outside air on the exhaust; and the gas discharged from the first air outlet 12 cannot be retained in the second shell 6, avoiding the gas circulation in the second shell 6. When the negative ion generator is started, the discharged gas can be prevented from circulating twice into the first shell 1, thereby improving the efficiency of removing odor in the ultraviolet disinfection cabinet; in order to keep the ultraviolet disinfection cabinet clean, a HEPA filter 611 is provided at the entrance of the third air inlet 61 to reduce the dust entering the ultraviolet disinfection cabinet due to air flow.

[0048] like Figure 7 As shown, the ultraviolet disinfection cabinet provided in Example 1 of the utility model is preferably provided with a plurality of foot supports 63 at the bottom of the second shell 6 in order to better support the ultraviolet disinfection cabinet and prevent the second shell 6 from rubbing and colliding with objects. The foot supports 63 are distributed on the corners of the second shell 6, so that the ultraviolet disinfection cabinet can be fully stressed when placed on a horizontal plane, thereby avoiding direct contact and collision between the second shell 6 and objects when the ultraviolet disinfection cabinet is placed, thereby extending the service life of the ultraviolet disinfection cabinet.

[0049] like Figures 1-2As shown, the ultraviolet disinfection cabinet provided by Example 1 of the utility model is preferably provided with a plurality of convex curved surfaces 34 on the reflective inner tank 3 in order to further improve the ultraviolet disinfection efficiency. The convex curved surfaces 34 are in the shape of a regular hexagon and are closely arranged. The convex curved surfaces 34 of the regular hexagon have a strong reflection effect. The ultraviolet rays can have a wider irradiation angle after being reflected by the regular hexagonal convex curved surfaces 34, so that part of the ultraviolet rays that are not directly irradiated on the object can be reflected onto the object, thereby improving the disinfection effect of the ultraviolet rays on the object; in order to maximize the ultraviolet disinfection efficiency, the convex curved surfaces 34 on the two reflective inner tanks 3 are arranged opposite to each other, and the convex curved surfaces 34 face the object, so that the object can be simultaneously exposed to the direct light of the ultraviolet rays and the ultraviolet rays reflected by the convex curved surfaces 34.

[0050] like Figures 1 to 4 As shown, in the ultraviolet disinfection cabinet provided by Embodiment 1 of the utility model, preferably, in order to obtain a good ultraviolet light effect, the UV irradiation assembly 2 includes a plurality of UV lamp beads 21, and the arrangement of the lamp beads 21 can make the first shell 1 irradiated with ultraviolet light, thereby improving the disinfection effect on the object and increasing the coverage area of ​​the ultraviolet light on the object; in order to arrange the UV lamp beads 21 in an orderly manner on each side of the first shell 1 and increase the coverage area of ​​the ultraviolet light on the object, all the UV lamp beads 21 are arranged equidistantly in the horizontal direction, and the horizontal direction here can refer to the horizontal direction of the UV lamp beads 21 on each side of the first shell 1;

[0051] In order to more effectively utilize the ultraviolet rays refracted by the reflective inner liner 3, a UV irradiation component 2 is provided on the front side, rear side, left side and right side of the first shell 1, and two UV irradiation components 2 are provided on the upper side and lower side of the first shell 1. The two UV irradiation components 2 are arranged side by side. Since the UV irradiation components 2 on the upper side and lower side of the first shell 1 have a better ultraviolet refraction angle than other sides, the UV irradiation components 2 on the upper side and lower side of the first shell 1 can more easily reflect ultraviolet rays to the side of the object through the reflective inner liner 3, thereby improving the disinfection effect on the object.

[0052] like Figure 8As shown, the ultraviolet disinfection cabinet provided by Example 1 of the utility model is preferably provided with a plurality of lamp holes 13 corresponding to the UV lamp beads 21 on the side of the first shell 1 in order to install the UV lamp beads 21, and the UV lamp beads 21 are located inside the lamp holes 13; in order to increase the area of ​​ultraviolet rays emitted by the UV lamp beads 21 and increase the coverage area of ​​the ultraviolet rays emitted by the UV lamp beads 21 on the object, the cross-section of the lamp holes 13 is made square, and the cross-section of the lamp holes 13 gradually increases from the bottom to the top, and the side walls of the lamp holes 13 are in an inclined state, and the ultraviolet rays emitted by the UV lamp beads 21 can be emitted along the side walls of the lamp holes 13, which expands the area of ​​ultraviolet rays emitted by the UV lamp beads 21 compared to the vertical side walls of the lamp holes 13; further, in order to avoid the situation where the opening 31 is smaller than the lamp hole 13, the horizontal projection of the top cross-section of the lamp hole 13 is made to coincide with the horizontal projection of the opening 31.

[0053] To sum up, the ultraviolet disinfection cabinet provided by the utility model can solve the problem in the prior art that during disinfection, objects will block most of the ultraviolet light emitted by the rotating ultraviolet lamp bead rod at the bottom of the body, and the main light source cannot be reflected through the reflective inner tank, resulting in poor disinfection effect on the top and sides of the object. It can reflect ultraviolet rays from multiple angles through the reflective inner tank, thereby enhancing the disinfection ability on the top and sides of the object.

Such variations do not affect the essential content of the present utility model, and will not be described in detail here.

It should be understood that the utility model is not limited to the above-mentioned specific embodiments, and the devices and structures that are not described in detail should be understood to be implemented in a common manner in the art; any technician familiar with the art can make many possible changes and modifications without departing from the technical solution of the utility model, or modify them into equivalent embodiments with equivalent changes, which does not affect the essential content of the utility model.
