Description

Technical Field

[0001] This utility model relates to the technical field of virus filtration equipment accessories, and in particular to a filter element for removing original viruses. Background Technology

[0002] In various spaces within medical facilities, the air may contain a variety of fungi, bacteria, and viruses, as well as their attachments. These gases containing fungi, bacteria, or viruses continuously spread, multiply, and proliferate in the air, easily exposing medical staff and patients to polluted air and causing cross-infection among the population.

[0003] Current air filtration systems typically use filters that are effective at filtering larger particles and have some effect on bacteria, but they are less effective at filtering viruses, thus failing to achieve the intended purpose for users. Furthermore, current filters are usually designed as a single unit, requiring the entire filter to be replaced rather than the individual filter section, resulting in high operating costs.

[0004] Therefore, existing filter cartridges suffer from poor filtration performance and the inability to replace the filter section independently. Summary of the Invention

[0005] This utility model provides a filter cartridge for removing original viruses, which solves the technical problems of poor filtration effect and inability to replace the filter part separately in the prior art.

The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0036] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0037] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0038] Reference Figures 1 to 6 As shown, a filter cartridge for removing the original virus includes a housing assembly 1;

[0039] and filter element assembly 2, wherein the filter element assembly 2 is disposed within the housing assembly 1;

[0040] The filter element assembly 2 includes an upper filter element 21, an antibacterial and sterilizing filter element 22, and a lower filter element 23, wherein the antibacterial and sterilizing filter element 22 is located between the upper filter element 21 and the lower filter element 23;

[0041] The housing assembly 1 includes an outer shell 11 and an inner shell 12 disposed within the outer shell 11. At least a portion of the filter element assembly 2 is located within the inner shell 12. The outer shell 11 is fitted over the inner shell 12. The outer shell 11 includes an upper shell 111 and a lower shell 112 disposed within the upper shell 111. A sealing ring 113 is provided between the upper shell 111 and the lower shell 112.

[0042] One end of the inner shell 12 abuts against the upper filter element 21, and the other end of the inner shell 12 abuts against the lower filter element 23. The outer shell 11 includes an air inlet 114 and an exhaust 115. Gas passes through the air inlet 114, the upper filter element 21, the antibacterial and sterilizing filter element 22, and the lower filter element 23 in sequence. Gas passing through the lower filter element 23 is output through the exhaust 115.

[0043] In some embodiments, the antibacterial and sterilizing filter element 22 may employ a filter element structure with a nano-copper antibacterial and sterilizing layer.

[0044] Reference Figures 1 to 6 As shown, in some embodiments, both the upper filter element 21 and the lower filter element 23 may include non-woven fabric to optimize the filtration effect of the upper filter element 21 and the lower filter element 23.

[0045] In some embodiments, the housing assembly 1 includes an upper housing 111, a lower housing 112, and an inner housing 12, i.e., the housing assembly 1 adopts a split structure. This split structure may cause gas leakage. Therefore, by making one end of the inner housing 12 abut against the upper filter element 21 and the other end of the inner housing 12 abut against the lower filter element 23, a good seal is maintained between the inner housing 12 and the filter element assembly 2 to prevent gas leakage.

[0046] Meanwhile, an outer shell 11 is fitted over the inner shell 12, and the outer shell 11 is composed of an upper shell 111, a lower shell 112, and a sealing ring 113. The outer shell 11 also has good sealing performance. The outer shell 11 and the inner shell 12 are used to provide a double seal for the filter element assembly 2, thereby giving the housing assembly 1 good sealing performance and making it difficult for gas to leak.

[0047] Reference Figures 1 to 6 As shown, in some embodiments, the upper filter element 21 includes an upper filter body 211 and an upper sealing body 212 disposed on the upper filter body 211. The upper sealing body 212 is disposed at the end of the upper filter body 211 away from the antibacterial and sterilizing filter element 22. The upper sealing body 212 is provided with an upper through hole for gas to pass through. The inner shell 12 abuts against the upper sealing body 212.

[0048] The upper sealing body 212 can be made of a sealing and elastic material such as rubber. When the inner shell 12 comes into contact with the upper sealing body 212, the upper sealing body 212 undergoes a certain elastic deformation, which makes the inner shell 12 and the upper sealing body 212 have better sealing performance.

[0049] In some embodiments, the diameter of the upper sealing body 212 is larger than the diameter of the upper filter element 21, and all the upper through holes are located within the inner shell 12. "All upper through holes are located within the inner shell 12" means that all the upper through holes are located within the space enclosed by the inner shell 12.

[0050] In some embodiments, the upper sealing body 212 is provided with an upper sealing ring groove 213, and one end of the inner shell 12 extends into the upper sealing ring groove 213.

[0051] The upper sealing ring groove 213 effectively increases the contact area between the inner shell 12 and the upper sealing body 212, thereby giving the inner shell 12 and the upper sealing body 212 better sealing performance.

[0052] In some embodiments, the lower filter element 23 includes a lower filter body 232 and a lower sealing body 231 disposed on the lower filter body 232. The lower sealing body 231 is disposed at one end of the lower filter body 232 away from the antibacterial and sterilizing filter element 22. The lower sealing body 231 is provided with a lower through hole for gas to pass through. The inner shell 12 abuts against the lower sealing body 231.

[0053] The structure of the lower sealing body 231 is the same as that described above for the upper sealing body 212.

[0054] Reference Figures 1 to 6 As shown, in some embodiments, the diameter of the lower sealing body 231 is larger than the diameter of the lower filter element 23, all the lower through holes are located inside the inner shell 12, the diameter of the lower sealing body 231 is equal to the diameter of the upper sealing body 212, and the lower sealing body 231 and the upper sealing body 212 are coaxially arranged.

[0055] In some embodiments, the lower sealing body 231 is provided with a lower sealing ring groove 233, and one end of the inner shell 12 extends into the lower sealing ring groove 233.

[0056] The lower sealing ring groove 233 provides a larger contact area between the inner shell 12 and the lower sealing body 231, resulting in better sealing performance between the inner shell 12 and the lower sealing body 231.

[0057] In some embodiments, a receiving cavity is provided between the upper housing 111 and the inner housing 12, and the lower housing 112 is provided with an extension cylinder 1121 extending into the receiving cavity. The length of the extension cylinder 1121 is equal to the depth of the receiving cavity, and the extension cylinder 1121 and the lower housing 112 are an integral structure.

[0058] Understandably, a sealing layer can be provided between the receiving cavity and the extension cylinder 1121. That is, a sealing layer can be provided on the extension cylinder 1121. The sealing layer makes the upper housing 111 and the lower housing 112 have a larger contact area, thereby improving the sealing performance of the outer shell 11.

[0059] Reference Figures 1 to 6 As shown, in some embodiments, the outer arm of the extension cylinder 1121 is provided with an external thread, and the receiving cavity is provided with an internal thread that mates with the external thread of the extension cylinder 1121.

[0060] The threaded connection between the extension sleeve 1121 and the receiving cavity can be a pipe thread to further improve the sealing performance between the upper and lower shells.

[0061] In some embodiments, the lower housing 112 is provided with a stepped surface for positioning the sealing ring 113, and the sealing ring 113 is located between the stepped surface and the lower end surface of the upper housing 111.

[0062] The sealing ring 113 can be made of materials such as rubber. The sealing ring 113 can be bonded to the lower end of the upper housing 111, or it can be bonded to the stepped surface.

[0063] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.

[0064] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here.
