Description

Technical Field

[0001] This utility model relates to an air filter element and belongs to the field of gas filtration technology. Background Technology

[0002] Existing air filter cartridges are mainly pleated cartridges. Some cartridges requiring additional functions use additional functional filters, while others use a housing structure with a cavity to add functional fillers. The housing structure that houses the cavity usually has an openable cover, which presents the problem of the additional functional components being replaceable, and the openable cover also carries the risk of falling off. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model provides an air filter element with a non-removable additional module, thus preventing the non-destructive replacement of additional functional components and the detachment of the cover plate.

[0004] The technical solution of this utility model is as follows: An air filter element with a non-removable additional module includes a rim, a pleated filter element, a bracket, and a functional item container. The bracket is fixedly connected to the rim and located within the pleated structure of the pleated filter element. The bracket has an installation groove for accommodating the functional item container. The functional item container is fixedly connected to both sides of the installation groove by a plurality of locking structures. The locking structures include mutually cooperating protrusions and bayonets. The functional item container includes a box body and a cover plate fixedly connected to the box body.

[0005] Furthermore, the locking structure is located on both sides of the functional object receiving box along its length.

[0006] Furthermore, the locking structures on both sides are arranged symmetrically.

[0007] Furthermore, the protrusion is a wedge-shaped block, and the side of the wedge-shaped block facing the assembly direction of the protrusion and the bayonet is a slope.

[0008] Furthermore, the bracket has support portions at both ends of the mounting groove, and the cover plate is located at the end of the box body, with the cover plate tightly attached to the support portions.

[0009] Furthermore, the cover plate is fixed to the box body by ultrasonic welding.

[0010] Furthermore, the bracket includes a windward surface and a fixed surface, the end of the fixed surface is fixedly connected to the surrounding edge, and the windward surface is provided with a plurality of guide holes.

[0011] Furthermore, the windward surface is a convex arc surface.

[0012] Furthermore, the bracket and the functional container are located on the air outlet side of the pleated filter element.

[0013] Compared with the prior art, the advantages of the technical solution provided by this utility model are as follows: This invention utilizes a locking structure formed by protrusions and bayonets to create a non-destructive, non-removable structure between the functional material container and the mounting groove. Simultaneously, the container body and cover are also fixedly connected, preventing the functional material inside from being replaced, thus improving safety. Furthermore, since disassembly and replacement are unnecessary, the entire air filter element can be replaced after assembly and at the end of its service life, significantly reducing the risk of falling and improving reliability. When the functional material is a volatile antibacterial material, a non-removable functional material container with a sealed structure extends the lifespan of the antibacterial module and can be maintained and replaced along with the filter element. From a production perspective, the mold structure for generating the protrusion and bayonet structure is relatively simple, reducing mold costs. Attached Figure Description

[0022] The present invention will be further described below with reference to the embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. After reading this description, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0023] Example 1, please refer to Figures 1 to 6 As shown, the non-removable air filter element of this embodiment can be applied to the vehicle's air conditioning system or other air filtration devices. The air filter element mainly includes a perimeter 1, a pleated filter element 2, a bracket 3, and a functional housing 4. The perimeter 1 is fixedly bonded around the pleated filter element 2 to stabilize the overall shape of the pleated filter element 2.

[0024] The bracket 3 serves as a transition component for the fixed installation of the functional material container 4, and is fixedly connected to the surrounding edge 3. The functional material container 4 is mainly used to place volatile substances with additional functions to achieve air sterilization, odor enhancement, etc. Therefore, in this embodiment, the bracket 3 and the functional material container 4 are located on the air outlet side of the pleated filter element 4 to avoid the pleated filter element 4 from blocking the volatile substances and losing its function.

[0025] The bracket 3 has a mounting groove 301 for accommodating the functional item container 4. The mounting groove 301 is elongated, and the functional item container 4 matches the shape of the mounting groove 301. The functional item container 4 includes a box body 401 and a cover plate 402 fixedly connected to the box body 401. The cover plate 402 contains the volatiles in the box body 401. The functional item container 4 is fixedly connected to both sides of the mounting groove 301 by several locking structures, which include mutually cooperating protrusions 5 and bayonets 6. The bracket 3 and the functional item container 4 are fixed by the locking structures, and the bracket 3 is also fixed to the surrounding edge 1, thereby fixing the position of the functional item container 4. The cover plate 402 is fixed to the box body 401 of the functional item container. In this embodiment, the cover plate 402 is fixed by ultrasonic welding, and other methods are used in other embodiments. On the one hand, this prevents the volatiles from being easily replaced. On the other hand, the steps of fixing the bracket 3 to the edge 1 and fixing the functional material container 4 to the bracket 3 are separated. The bracket 3 is fixed to the edge 1 using a high-temperature molten colloid. After fixing in two steps, the high-temperature colloid is prevented from contacting the functional material container 4 and affecting the use of the volatiles of the additional function. In this embodiment, the protrusion 5 is provided on the functional material container 4, and the snap 6 is provided on the mounting groove 301. In some other embodiments, the protrusion 5 can be provided on the mounting groove 301, and the snap 6 can be provided on the functional material container 4. Alternatively, the protrusion 5 and the snap 6 can be alternately provided on the mounting groove 301 and the functional material container 4.

[0026] In a preferred embodiment, the locking structures are located on both sides of the functional item receiving box 4 along its length. This allows for the arrangement of more locking structures, increasing the number of connection points between the functional item receiving box 4 and the bracket 3, and making disassembly more difficult.

[0027] In the locking structure, the protrusion 5 is a wedge-shaped block, and the side of the wedge-shaped block facing the assembly direction of the protrusion 5 and the bayonet 6 is a slope. The bayonet 6 is a rectangular through hole that matches the shape of the wedge-shaped block. This makes it easy for the protrusion 5 to engage with the bayonet 6 during assembly, but difficult to disengage from the bayonet 6, further increasing the difficulty of disassembly. It should be noted that in addition to setting the protrusion 5 as a wedge-shaped block, it can also be set as other shapes that can engage with the bayonet 6 but are easy to engage but difficult to disengage.

[0028] In this embodiment, the locking structures on both sides are arranged symmetrically. This makes it difficult to utilize the deformation on the opposite side to provide space for the protrusion 5 on this side to disengage from the latch 6.

[0029] As mentioned earlier, the bracket 3 is a transition component used to connect and fix the functional container box 4. Support portions 302 are provided at both ends of the mounting groove 301 on the bracket 3. Each support portion 302 includes a windward surface 302a and a fixing surface 302b. The fixing surfaces 302b are located on both sides of the windward surface 302a. The windward surfaces 302a of the two support portions 302 extend towards the middle to form the mounting groove 301. The ends of the fixing surfaces 302b are fixedly connected to the surrounding edge 1. To reduce the obstruction of airflow on the windward surface, several guide holes 302c are provided on the windward surface 302a of the support portion 302. Furthermore, the windward surface 302a as a whole is a convex arc surface, including the windward surface of the mounting groove 301 portion, which guides the airflow. The cover plate 402 of the functional material container 4 is located at the end of the box body 401. After the functional material container 4 is installed in the mounting groove 301, the cover plate 402 is tightly attached to the support part 302. This makes it difficult to break the connection between the cover plate 402 and the box body 401 to replace the additional functional volatiles in the box body 401.

[0030] Example 2, please refer to Figure 7 As shown, the difference between this embodiment and embodiment 1 lies in the structural arrangement of the mounting groove 301. In this embodiment, the mounting groove 301 is formed by extending and connecting the fixing surface 302b of the support part 302 of the bracket 3 towards the middle. The mounting groove 301 has a central open structure, and the central open structure constitutes the latch 6. The structure of the protrusion 5 on the box body 401 of the functional object receiving box 4 is the same as that in embodiment 1. The side of the open side of the mounting groove 301 cooperates with the protrusion 5 to restrict the protrusion 5 from coming out, thus ensuring the fixation of the functional object receiving box 4 and the bracket 3.
