[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] Please see Figure 1-3 This utility model provides an air conditioner filter cartridge, including two annular end caps 1 and a filter element body 2 located between the two annular end caps 1. The filter element body 2 is annular and includes an inner protective net 21 and an outer protective net 23. A filter element 22 is provided between the inner protective net 21 and the outer protective net 23. An annular groove 11 that cooperates with the filter element body 2 is provided at one end of the annular end cap 1 facing the filter element body 2. A locking mechanism for locking the filter element body is provided on the annular end cap 1.

[0023] Among them, combined Figure 1 and Figure 2 As shown, the inner diameter of the filter element 22 is the same as the outer diameter of the inner protective mesh 21, and the outer diameter of the filter element 22 is the same as the inner diameter of the outer protective mesh 23. The height of the inner protective mesh 21 and the height of the outer protective mesh 23 are the same. It should be noted that any parts not described in detail in this application are prior art.

[0024] Combination Figure 1 , Figure 3 As shown, the locking mechanism includes multiple locking elements 3 evenly distributed circumferentially along the annular end cover 1. There are four locking elements 3, each including a locking bolt 31. The threaded portion of the locking bolt 31 penetrates the side wall of the annular end cover 1 and extends into the annular recess 11, with a clamping element 33 at its end. The outer wall of the annular end cover 1 has a threaded hole that mates with the threaded portion of the locking bolt 31. During locking, rotating the locking bolt 31 moves the clamping element 33 towards the filter element body 2, ultimately causing the clamping element 33 to abut against the outer wall of the filter element body 2, thus locking the filter element body 2. During unlocking, rotating the locking bolt 31 moves the clamping element 33 away from the filter element body 2, ultimately separating the clamping element 33 from the outer wall of the filter element body 2, thus unlocking the filter element body 2.

[0025] Furthermore, the clamping member 33 is plate-shaped or arc-shaped and made of rubber material. This prevents damage to the filter element body 2 during tightening. The locking bolt 31 is a wing bolt. A locking nut 32 is provided on the threaded part of the locking bolt 31, located on the outside of the annular end cap 1. When the clamping member 33 abuts against the outer wall of the filter element body 2, the locking nut 32 is rotated to tighten the locking bolt 31, causing the locking nut 32 to abut against the outer wall of the annular end cap 1, preventing the locking bolt 31 from falling off and further improving the stability of the tightening.

[0026] This application adopts a split structure, with the two ends of the filter element body 2 respectively installed in the annular grooves 11 of the two annular end caps 1, and then locked with a locking mechanism, which makes the filter element body 2 easy to install and disassemble, improves the efficiency of filter element body replacement or cleaning, and thus improves the efficiency of inspection and maintenance.

[0027] Of course, this utility model is not limited to the embodiments described above. Several other embodiments based on the design concept of this utility model are also provided below.

[0028] For example, in other embodiments, unlike the embodiments described above, such as... Figure 4 As shown. The clamping element 33 is a clamping plate, which is connected to a buffer plate 35 by multiple springs 34. The buffer plate 35 is made of rubber. Rotating the locking nut 32 moves the clamping element 33 closer to the filter element body 2. The buffer plate 35 contacts the filter element body 2 first, and the springs 34 are compressed, thus buffering the clamping force and preventing damage to the filter element body 2.

[0029] For example, in other embodiments, unlike the embodiments described above, the filter element 22 made of polyurethane material is coated with a waterproof and oil-repellent layer. The filter element 22 of this application uses polyurethane material, and a waterproof and oil-repellent layer is coated on the surface of the polyurethane material. This gives the filter element properties of moisture resistance, acid and alkali resistance, and oxidation resistance, without affecting the filtration efficiency of the air conditioning filter cartridge or the airflow.

[0030] It should be noted that the above embodiments are only used to illustrate the present utility model, but the present utility model is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
