They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] like Figure 1 As shown, this utility model provides a fragrance liquid filtration device. The fragrance liquid filtration device includes a housing 1, a top cover 2, a filter element 3, and an elastic element 4.

[0033] Specifically, the housing 1 has a receiving cavity with an opening communicating with it. The filter element 3 is placed inside the receiving cavity. The top cover 2 is used to open or close the opening. A feed inlet 11 is located at one end of the housing 1 near the top cover 2, communicating with the receiving cavity. A discharge outlet 12 is located at the other end of the housing 1 away from the top cover 2, communicating with the receiving cavity. The elastic element 4 is configured to always drive the filter element 3 to move away from the top cover 2. This filtration device inputs flavoring liquid from the top and discharges it from the bottom. The flavoring liquid flows through the filter element 3, filtering impurities within it. Simultaneously, the elastic element 4 prevents the filter element 3 from moving, ensuring filtration quality, preventing impurities from entering the tobacco, avoiding nozzle clogging, ensuring uniform spraying of the flavoring liquid, and improving tobacco quality.

[0034] Optionally, such as Figure 2 As shown, the receiving cavity includes a first cavity 13 and a second cavity 14 that are connected. The inner diameter of the first cavity 13 is smaller than the inner diameter of the second cavity 14. A stepped surface 15 is formed between the first cavity 13 and the second cavity 14. One end of the filter element 3 can be inserted into the first cavity 13, and the other end of the filter element 3 can abut against the stepped surface 15. An elastic element 4 is disposed in the second cavity 14. The inlet 11 is connected to the second cavity 14, and the outlet 12 is connected to the first cavity 13. Specifically, the aperture of the first cavity 13 is smaller than the aperture of the second cavity 14. The fragrance liquid first flows into the second cavity 14 and then into the filter element 3, which allows the fragrance liquid to flow through the entire filter element 3, ensuring the filtration effect.

[0035] Optionally, such as Figure 3 As shown, the filter element 3 includes a filter section 31 and a support section 32. The support section 32 protrudes circumferentially from one end of the filter section 31. The filter section 31 is inserted into the first cavity 13. The support section 32 can abut against the stepped surface 15. An elastic member 4 is disposed between the top cover 2 and the support section 32. Specifically, the filter section 31 has several filter holes arranged circumferentially to facilitate the flow of the fragrance liquid. The support section 32 is fixedly connected to the top end of the filter section 31. The filter section 31 and the support section 32 are coaxially arranged, and the diameter of the support section 32 is larger than the diameter of the filter section 31, so that the support section 32 can abut against the stepped surface 15. The diameter of the support section 32 is the same as the aperture of the second cavity 14, so that the outer edge of the support section 32 can fit against the hole wall of the second cavity 14, preventing the filter section 31 from moving and improving the stability of the filter element 3.

[0036] Optionally, the fragrance liquid filtration device further includes a first sealing element 5, which is disposed between the support portion 32 and the stepped surface 15. Specifically, the first sealing element 5 is a rubber gasket, and the filter element 3 passes through the first sealing element 5. The first sealing element 5 is deformed by the pressure of the elastic element 4, which can improve the sealing between the support portion 32 and the stepped surface 15, ensuring that the fragrance liquid can only pass through the filter element 3 and cannot pass through the gap between the filter element 3 and the first cavity 13, thus ensuring the filtration effect.

[0037] Optionally, such as Figure 4 As shown, the fragrance liquid filtration device also includes a nut 6, which is equipped with a retaining ring 61. One end of the top cover 2 can be inserted into the nut 6 and abut against the retaining ring 61, while the other end of the top cover 2 can be inserted into the second cavity 14. The nut 6 is threadedly connected to the housing 1. Specifically, the outer ring of the housing 1 is provided with external threads, and the inner ring of the nut 6 is provided with internal threads. The threaded connection between the nut 6 and the housing 1 facilitates the disassembly of the fragrance liquid filtration device and the replacement of the filter element 3. By setting different mesh sizes of the inner lining screen of the filter element 3, filter elements 3 of different specifications can be formed to achieve the matching use of fragrance liquids with different physical properties and particle sizes, thereby improving the versatility of the fragrance liquid filtration device.

[0038] Optionally, the top cover 2 has a conical cross-section, and the wall of the second cavity 14 is provided with an inclined arc surface 141, allowing the conical surface of the top cover 2 to fit against the inclined arc surface 141. Specifically, the bottom of the top cover 2 is inverted conical, and the top of the wall of the second cavity 14 is provided with an inclined arc surface 141. The retaining ring 61 of the nut 6 abuts against the top wall of the top cover 2, bringing the top cover 2 against the housing 1. The fit between the conical surface and the inclined arc surface 141 improves the sealing between the top cover 2 and the housing 1, while limiting the downward pressure depth of the top cover 2. This allows the elastic element 4 to apply appropriate pressure to the first sealing element 5, preventing excessive pressure from damaging the first sealing element 5. Further, the elastic element 4 is a compression spring.

[0039] Optionally, such as Figure 5 As shown, the fragrance liquid filtration device also includes a handle 9, which is installed on the top wall of the top cover 2 and protrudes through the nut 6, making it convenient for staff to move the filtration device.

[0040] Optionally, the fragrance liquid filtration device further includes a second sealing element 7, which is disposed between the conical surface of the top cover 2 and the inclined arc surface 141. Specifically, the second sealing element 7 is a rubber sealing ring, which is fitted onto the conical surface of the top cover 2 to improve the sealing between the top cover 2 and the housing 1.

[0041] Optionally, the tapered surface of the top cover 2 is provided with an installation groove, and the second seal 7 is disposed in the installation groove to prevent the second seal 7 from falling off and to improve the stability of the second seal 7.

[0042] Optionally, the fragrance liquid filtration device further includes a positioning column 8, which is disposed within the second cavity 14, and an elastic element 4 is sleeved on the outer periphery of the positioning column 8. Specifically, the positioning column 8 has a cylindrical structure, is coaxially arranged with the filter element 3, is connected to the support part 32, and the elastic element 4 is sleeved on the outer periphery of the positioning column 8. Both ends of the elastic element 4 abut against the top cover 2 and the support part 32 respectively, preventing the elastic element 4 from tilting and ensuring the correct orientation of the elastic element 4.

[0043] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
