[0028] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0029] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0031] This application provides a filter element structure and an air conditioner to solve the problem of poor maintainability of the filter element. The following description will be provided in conjunction with the accompanying drawings.

[0032] This application provides a filter element structure, including a filter cartridge 1 and a filter screen 2. The filter screen 2 is provided with an installation part 21, and the side wall of the filter cartridge 1 is provided with a connector 11. The connector 11 is provided with a connecting groove 12 that is inserted and matched with the installation part 21. When the filter screen 2 is connected to the filter cartridge 1, the filter screen 2 is sleeved on the filter cartridge 1, and the installation part 21 is placed in the connecting groove 12.

[0033] By providing a connector 11 on the filter cartridge 1 and opening a connecting groove 12 on the connector 11, the filter screen 2 can be connected to the filter cartridge 1 by inserting the mounting part 21 from one side of the filter cartridge 1 into the connecting groove 12. When the filter screen 2 needs to be replaced, the filter screen 2 is pulled out from one side of the filter cartridge 1, so that the connector 11 is disengaged from the connecting groove 12. The installation and disassembly process of the filter screen 2 is simple and convenient, which solves the problem of poor maintainability of the filter element.

[0034] In this embodiment, the filter screen 2 is rectangular in shape, and there are two mounting parts 21. The two mounting parts 21 are integrally formed at both ends of the filter screen 2 in the width direction. The connector 11 also has two connecting grooves 12, and the mounting parts 21 and the connecting grooves 12 are arranged in a one-to-one correspondence. By inserting the two mounting parts 21 into the corresponding connecting grooves 12, the filter screen 2 and the filter cartridge 1 can be detachably connected.

[0035] The connector 11 includes a first connecting portion 111, a second connecting portion 112, and two third connecting portions 113. The first connecting portion 111 is fixedly connected to the filter cartridge 1. The second connecting portion 112 is fixedly connected to the side of the first connecting portion 111 away from the filter cartridge 1. The two third connecting portions 113 are respectively fixedly connected to both ends of the second connecting portion 112 along its length, and both third connecting portions 113 are located on the side of the second connecting portion 112 closer to the first connecting portion 111. The first connecting portion 111, the second connecting portion 112, and the third connecting portions 113 together define a connecting groove 12. A limiting block 114 is provided on the side of the third connecting portion 113 away from the second connecting portion 112. The limiting block 114 and the side wall of the filter cartridge 1 form a space for the filter screen 2 to extend into. The distance between the limiting block 114 and the side wall of the filter cartridge 1 is less than the thickness of the filter screen 2.

[0036] The filter cartridge 1 includes a cylindrical body 13 and an end cap 14. In this embodiment, the cylindrical body 13 is cylindrical and has multiple vent holes 131 spaced apart. The end cap 14 is detachably connected to the end of the cylindrical body 13. The end cap 14 and the cylindrical body 13 together define a cavity for accommodating solid purifiers. In this embodiment, the solid purifier is solid alkali particles. Specifically, the end cap 14 includes a closing part 141 and a locking part 142 connected in sequence. When the end cap 14 is connected to the cylindrical body 13, the closing part 141 abuts against the end face of the cylindrical body 13, and the locking part 142 is press-fitted with the inner wall surface of the cylindrical body 13. In addition, the end cap 14 has a disassembly hole 143 for engaging with external tools. The disassembly hole 143 communicates with the cavity. The disassembly hole 143 not only helps to increase the opening rate of the filter cartridge 1, but also facilitates the removal of the end cap 14 from the cylindrical body 13 by the operator using tools.

[0037] The filter element structure also includes a fixing bracket 3, on which a locking groove 33 is provided for engaging with the connector 11. Specifically, the fixing bracket 3 includes a first fixing part 31 and a second fixing part 32. The second fixing part 32 is integrally formed at one end of the first fixing part 31, and the locking groove 33 is located on the side of the second fixing part 32 away from the first fixing part 31. When the filter cartridge 1 is installed on the fixing bracket 3, the connector 11 engages with the locking groove 33, and the side of the second fixing part 32 away from the first fixing part 31 abuts against the side wall of the filter cartridge 1.

[0038] This application also provides an air conditioner that includes the filter structure described above. Since this air conditioner has the aforementioned filter structure, it possesses at least some or all of the beneficial effects of the filter structure, which will not be elaborated upon here. In this embodiment, the fixed bracket 3 is disposed on one side of the evaporator of the air conditioner, and the filter cartridge 1 is disposed on the fixed bracket 3. The filter cartridge 1 is located within the return air duct of the air conditioner. By placing the filter cartridge 1 within the return air duct, it is beneficial to purify the air flowing through the air conditioner, thereby achieving the purification of indoor air.

[0039] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
