Description

Technical Field

[0001] The utility model relates to the technical field of air purification, and more specifically to an anti-leakage UV lamp purification device. Background Art

[0002] In order to prevent UV leakage, the existing UV lamp purification device is set behind the filter. The consequence is that bacteria need to be filtered by the filter before being irradiated and sterilized by the UV lamp. Most of the bacteria are intercepted and adsorbed by the filter and cannot be completely killed. The filter is contaminated for a long time, resulting in poor air purification effect and greatly shortening the service life of the filter. If the UV lamp is set in front of the filter, there is no filter to block it, and there is a risk of direct UV leakage and accidental injury to the human body. Utility Model Content

[0003] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0004] A leakage-proof UV lamp purification device comprises a shell, a blower is arranged in the shell, a sterilization cavity is arranged in the shell, the outer side of the sterilization cavity is open, and the inner side is connected with the air inlet of the blower, a UV lamp is arranged on the inner peripheral wall of the sterilization cavity, a filter covering the air inlet of the blower is arranged between the inner side of the sterilization cavity and the UV lamp, a door panel is arranged on the outer side of the sterilization cavity of the shell, there is a distance between the door panel and the sterilization cavity, a blocking edge is protruded on the shell and around the door panel, the door panel at least covers the sterilization cavity, and there is a gap between the peripheral side wall of the door panel and the blocking edge, and the outside air enters the sterilization cavity from the gap.

[0025] A leak-proof UV lamp purification device, such as Figure 1 and Figure 2 As shown, it includes a shell 1, a blower 2 is arranged in the shell 1, a sterilization cavity 3 is opened in the shell 1, the outer side of the sterilization cavity 3 is open, and the inner side is provided with a through hole and connected with the air inlet 201 of the blower 2, a UV lamp 4 is arranged on the inner wall of the sterilization cavity 3, and a filter 5 covering the air inlet 201 of the blower 2 is arranged between the inner side of the sterilization cavity 3 and the UV lamp 4. The blower 2 sucks air from the outside into the sterilization cavity 3, the air is first irradiated by the UV lamp 4 for sterilization, and then filtered by the filter 5 before entering the blower 2.

[0026] The shell 1 is provided with a door panel 6 on the outside of the sterilization chamber 3, and there is a gap between the door panel 6 and the sterilization chamber 3. A blocking edge 7 is protruded on the shell 1 and around the door panel 6. The door panel 6 at least covers the sterilization chamber 3, and there is a gap between the peripheral side wall of the door panel 6 and the blocking edge 7. The depth of the blocking edge 7 is not less than the gap between the door panel 6 and the sterilization chamber 3, so that the UV leaked at the gap will be blocked by the blocking edge 7, and the outside air enters the sterilization chamber 3 through the gap and the gap between the door panel 6 and the sterilization chamber 3. The light emitted by the UV lamp 4 on the inner peripheral wall of the sterilization chamber 3 will be blocked by the door panel 6, and the light scattered from the peripheral side of the door panel 6 will be blocked by the blocking edge 7, so that the light will not leak.

[0027] like Figure 3 and Figure 4 As shown, the sterilization chamber 3 is square, and a receiving groove 8 is provided on the inner wall of the sterilization chamber 3, specifically, a receiving groove 8 is provided on the inner walls on the left and right sides, and the receiving groove 8 extends in the vertical direction.
