DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] See also Figure 1-5 The utility model provides a technical solution: a sterilization ventilation device, including a ventilation body 1, a sterilization net 2, a first filter 3, and a second filter 4. Positioning slots 11 are respectively provided on both sides of the inner wall of the ventilation body 1. Fixing members 5 are detachably installed on both sides of the inner wall of the ventilation body 1. The fixing members 5 include a fixing plate 51 that is slidably engaged in the positioning slot 11. A first movable plate 6 is slidably connected inside the fixing plate 51. A second movable plate 61 is slidably connected inside the first movable plate 6.

[0023] A connecting block 63 is fixedly mounted on one end of the inner side of the fixing member 5, the first movable plate 6 and the second movable plate 61, and the sterilizing net 2, the first filter screen 3 and the second filter screen 4 are fixedly mounted on the connecting block 63 respectively. An adjusting screw 62 is connected through the fixing plate 51 and the first movable plate 6;

[0024] The induced draft fan arranged inside the ventilation body 1 can introduce the external flowing air into the room, and the flowing air can be filtered and sterilized by passing through the filter screen and the sterilization net 2 structure in turn. The filtering and sterilization of the internal filter screen and the sterilization net 2 of the sterilization ventilation device is a prior art and will not be described in detail here.

[0025] The fixed plate 51, the first movable plate 6 and the second movable plate 61 form a telescopic rod structure. The fixed plate 51 can be slidably engaged in the positioning slot 11 provided on the inner wall of the ventilation main body 1 and positioned by the fixing screw 7, so that the filter screen and the sterilization screen 2 installed on the fixed plate 51 and the movable plate can be integrally withdrawn and disassembled from the ventilation main body 1, which is convenient for disassembly, maintenance and cleaning of multiple groups of filter mechanisms in the ventilation device;

[0026] The fixed plate 51, the first movable plate 6 and the second movable plate 61 form a telescopic rod structure. The filter screen and the sterilization net 2 can be respectively connected to the telescopic joint position on the inner side of the telescopic rod through the connecting block 63. In this way, by rotating the adjusting screw 62, the second movable plate 61 can drive the filter screen and the sterilization net 2 to unfold in sequence, so that the filter screen and the sterilization net 2 can be unfolded to the set spacing value, thereby ensuring the spacing between the filter screen and the filter screen and the sterilization net 2, and avoiding the distance between the filter screen and the sterilization net 2 being too close and easily blocked by the filter, affecting normal ventilation filtration and sterilization.

[0027] Among them, a fixing groove 12 is opened at one end of the inner wall of the positioning slot 11, and a fixing screw 7 is installed inside the fixing slot 12 through a thread. The fixing screw 7 is used to position the fixing part 5. The fixing plate 51 can be slidably engaged into the positioning slot 11 opened on the inner wall of the ventilation main body 1, and is positioned by the fixing screw 7, so that the filter screen and the sterilization net 2 installed on the fixing plate 51 and the movable plate can be pulled out and disassembled as a whole from the ventilation main body 1.

[0028] Among them, the first movable plate 6 is a T-shaped structure at one end close to the fixed plate 51, and the second movable plate 61 is a T-shaped structure at one end close to the first movable plate 6. The fixed plate 51, the first movable plate 6 and the second movable plate 61 form a telescopic rod structure, and the filter screen and the sterilization net 2 can be respectively connected to the telescopic joint position inside the telescopic rod through the connecting block 63.

[0029] Among them, the adjusting screw 62 and the second movable plate 61 are connected by threads, and the end of the first movable plate 6 close to the second movable plate 61 is a convex structure. By rotating the adjusting screw 62, the second movable plate 61 can drive the filter screen and the sterilization net 2 to unfold in sequence, so that the filter screen and the sterilization net 2 can be unfolded to the set spacing value, thereby ensuring the spacing between the filter screen and the filter screen and the sterilization net 2.

[0030] Working principle: When installing the filter screen and the sterilizing net 2 in the sterilizing ventilation device, the fixing plate 51 is slidably engaged in the positioning slot 11 provided on the inner wall of the ventilation main body 1, and is positioned by the fixing screw 7, and then the adjusting screw 62 is rotated so that the second movable plate 61 can drive the filter screen and the sterilizing net 2 to be unfolded in sequence, so that the filter screen and the sterilizing net 2 can be unfolded to the set spacing value, thereby ensuring the spacing between the filter screen and the filter screen and the sterilizing net 2, and avoiding the spacing between the filter screen and the sterilizing net 2 being too close and easily blocked by the filtered object, which affects the normal ventilation, filtration and sterilization;

[0031] Similarly, when disassembling multiple groups of filtering mechanisms in the sterilization ventilation device, the fixing screws 7 at the outer end of the fixed plate 51 are disassembled, and then the fixed plate 5 and the first movable plate 6 and the second movable plate 61 are pulled out from the ventilation main body 1. In this way, the filter screen and the sterilization net 2 installed on the fixed plate 51 and the movable plate can be pulled out and disassembled as a whole from the ventilation main body 1, which is convenient for the disassembly, maintenance and cleaning of the multiple groups of filtering mechanisms in the ventilation device.
