[0025] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.

[0026] Embodiment 1

[0027] Please refer to Figures 1-5 The above technical solutions are described in detail through the following embodiments.

[0028] A deodorizing device for an experimental animal room comprises:

[0029] The device main body 1 comprises an air extraction assembly and an air inlet assembly. The air extraction assembly is used to extract air from the air inlet assembly. The air extraction assembly and the air inlet assembly are separated by a partition plate 14. A filter assembly 2 is arranged below the partition plate 14 and in the air inlet assembly. The filter assembly 2 is externally provided with a sealing assembly 3.

[0030] The air extraction assembly comprises a machine box 11. A fan 12 is fixedly installed on the top of the machine box 11 by means of bolts. The fan 12 can discharge air outward when working, so that the machine box 11 is in a negative pressure state. The fan 12 is fixedly installed at the bottom of the machine box 11 by means of bolts. The machine box 11 can average the pressure, thereby avoiding the problem that different filter assemblies 2 have different negative pressures due to the low negative pressure between the fans 12.

[0031] The air inlet assembly comprises a filter screen 13. A bottom plate 15 is welded to the bottom of the filter screen 13. The partition plate 14 is arranged on the top of the filter screen 13. A plurality of through holes are arranged at the corresponding positions of the bottom plate 15 and the partition plate 14. A threaded sleeve 16 is arranged on the bottom surface of the partition plate 14 and outside the through holes.

[0032] The filter screen 13 is welded to the machine box 11. The filter screen 13 is used to isolate larger impurities.

[0033] The filter assembly 2 comprises a filter core 21. The filter core 21 is in a hollow cylindrical shape. Cover plates 24 are clamped to the upper and lower ends of the filter core 21. The top of the upper cover plate 24 is threadedly connected to the threaded sleeve 16.

[0034] The filter core 21 is made of a filter material capable of adsorbing odor. A gas channel 22 is arranged through the center of the filter core 21. The end of the gas channel 22 is a circular mounting groove 23. The inner diameter of the mounting groove 23 is larger than that of the gas channel 22.

[0035] The cover plate 24 is made of plastic material, and a hollow connecting pipe 25 is arranged on the side of the cover plate 24 close to the filter element 21. The inner diameter of the connecting pipe 25 is the same as that of the air duct 22.

[0036] The upper cover plate 24 is threadedly connected with the threaded sleeve 16, and can fix the filter element 21.

[0037] The cover plate 24 is hollow and annular, and a plurality of clamping grooves 26 are uniformly arranged on the side of the cover plate 24 close to the filter element 21.

[0038] When the fan 12 works, a negative pressure is formed in the cabinet 11, and the negative pressure in the cabinet 11 is transmitted to the filter element 21, so that air is sucked from the outside of the filter element 21, passes through the filter element 21, enters the air duct 22, and then enters the cabinet 11. The odor molecules in the air are adsorbed by the filter element 21.

[0039] The sealing assembly 3 comprises a protection cylinder 31, which is slidingly installed outside the filter element 21. A clamping block 32 is arranged on the inner side of the top of the protection cylinder 31, and the clamping block 32 is matched with the clamping groove 26.

[0040] The protection cylinder 31 is used for protecting the filter element 21, and the clamping block 32 is clamped with the clamping groove 26, so that the relative rotation between the protection cylinder 31 and the filter element 21 is prevented.

[0041] A sealing plate 33 is welded on the inner side of the bottom of the protection cylinder 31, and a guide rod 34 is welded on the side of the sealing plate 33 close to the filter element 21. The guide rod 34 penetrates the cover plate 24 and is inserted into the filter element 21, and the guide rod 34 can slide in the cover plate 24 and the filter element 21.

[0042] A handle 36 is welded on the middle of the bottom of the cover plate 24. The handle 36 is used for pushing and pulling the cover plate 24, so as to drive the protection cylinder 31 to move along the filter element 21 in the axial direction. The guide rod 34 can avoid shaking when the protection cylinder 31 moves, and can also protect the air duct 22.

[0043] A sealing ring 35 is arranged on the outer side of the top end of the guide rod 34, and the guide rod 34 is in interference fit with the center of the cover plate 24 through the sealing ring 35.

[0044] When the sealing ring 35 is in interference fit with the upper cover plate 24, the air duct 22 can be sealed. At this time, the protection cylinder 31 wraps the filter element 21 and is clamped with the upper cover plate 24, so as to seal the outside of the filter element 21.

[0045] When the sealing ring 35 is in interference fit with the lower cover plate 24, the air duct 22 and the filter element 21 are completely exposed. At this time, the friction between the sealing ring 35 and the cover plate 24 can prevent the sealing assembly 3 from sliding upward due to the negative pressure of the cabinet 11, which affects the filtering efficiency of the filter element 21. At the same time, it can also prevent air from directly entering the air duct 22 from the lower end of the air duct 22.

[0046] The operator of the embodiment ensures that the protection cylinder 31 wraps the filter element 21, holds the handle 36, and ensures that the sealing ring 35 is above and the filter element 21 is in a vertical state when using the device.

[0047] The filter assembly 2 and the sealing assembly 3 are inserted from below the bottom plate 15 until the upper cover plate 24 is in contact with the threaded sleeve 16.

[0048] The handle 36 is rotated to drive the protection cylinder 31 to rotate, and the cover plate 24 is rotated by the clamping block 32. The upper cover plate 24 is screwed into the threaded sleeve 16 until it cannot be rotated any further.

[0049] A downward force is applied to the handle 36 to drive the protection cylinder 31 to slide downward until the sealing ring 35 is in interference fit with the lower cover plate 24. At this time, the clamping block 32 is clamped into the clamping groove 26 of the lower cover plate 24, and the installation of the filter assembly 2 is completed.

[0050] After all the filter assemblies 2 are installed, the fan 12 is controlled to work, so that the cabinet 11 is in a negative pressure state. Air is sucked from the outside of the filter element 21, filtered through the filter element 21, enters the cabinet 11 through the air duct 22, and is then discharged by the fan 12. Deodorization is achieved.

[0051] When the filter element 21 needs to be replaced, the corresponding handle 36 is pushed upward to slide the protection cylinder 31 upward until the sealing ring 35 is in interference fit with the upper cover plate 24. At this time, the clamping block 32 is clamped into the clamping groove 26 of the upper cover plate 24.

[0052] The handle 36 is rotated in a counterclockwise direction to unscrew the upper cover plate 24 from the threaded sleeve 16, and then the filter assembly 2 and the sealing assembly 3 are pulled out from below the bottom plate 15 to replace the new filter assembly 2.

[0053] The basic principles, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only preferred examples of the present application and do not limit the present application.
