[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0019] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention 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. Therefore, they should not be construed as limitations on this invention.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "configuration" should be interpreted broadly. For example, they can refer to a fixed connection or configuration, a detachable connection or configuration, or an integral connection or configuration. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] Please see Figures 1-5 In this embodiment of the present invention, a replaceable medical air purifier filter includes an outer protective net 1, with a top ring 2 fixedly connected to the top of the outer protective net 1. The inner walls of the outer protective net 1 and the top ring 2 share a purification cavity 11, with the top of the purification cavity 11 being through-hole. Multiple limiting posts 12 are evenly arranged on the inner wall of the purification cavity 11, with the bottoms of each limiting post 12 fixedly connected to the inner wall of the purification cavity 11, and all posts are cylindrical in shape. A filter element 13 is inserted into the inner wall of the purification cavity 11 located between the outer protective net 1 and the limiting posts 12. The inner wall of the filter element 13 is hollow, and the inner diameter of the filter element 13 matches the outer diameter formed by the multiple limiting posts 12.

[0022] The top of the top ring 2 is provided with a limiting connecting ring 3, and a through hole 31 is provided on the top of the limiting connecting ring 3. The inner diameter of the through hole 31 matches the inner diameter formed by the multiple limiting posts 12. In this way, when the filter element 13 is inserted into the purification cavity 11, the limiting connecting ring 3 can be sleeved on the limiting post 12 through the through hole 31, thereby fixing the filter element 13.

[0023] To further improve sealing performance, each limiting connecting ring 3 has a mounting groove 32 on its top, and a sealing strip 33 is fixedly connected inside the mounting groove 32. The sealing strip 33 can fit tightly with other components of the air purifier to prevent air leakage.

[0024] Based on Example 1, this example further optimizes the structure of the limiting connecting ring 3. Please refer to... Figure 3 and Figure 5 Hinges 34 are fixedly connected to the side walls at both ends of the limiting connecting ring 3, and rotating plates 35 are fixedly connected to the ends of the two hinges 34 away from the limiting connecting ring 3. Locking blocks 36 are fixedly connected to the bottom side walls of the two rotating plates 35 near the top ring 2. Simultaneously, limiting blocks 21 are fixedly connected to the outer walls of the top ring 2 that match the positions of the two locking blocks 36, and both limiting blocks 21 engage with the locking blocks 36 that match their positions.

[0025] Thus, when the filter element 13 needs to be removed from the purification chamber 11, simply rotate the rotating plate 35 to separate the locking block 36 from the limiting block 21, and then lift the limiting connecting ring 3 upwards. After replacing the filter element 13, the limiting connecting ring 3 is then fitted onto the limiting post 12, and the locking block 36 is engaged with the limiting block 21 by rotating the rotating plate 35. The entire process is simple and quick, greatly improving replacement efficiency.

[0026] The working principle of this utility model is as follows: When the filter element 13 needs to be replaced, first, rotate the rotating plate 35 to separate the locking block 36 from the limiting block 21, then lift the limiting connecting ring 3 upwards to remove it from the limiting post 12. Next, remove the old filter element 13 from the purification chamber 11 and insert the new filter element 13. Then, put the limiting connecting ring 3 onto the limiting post 12, and rotate the rotating plate 35 to engage the locking block 36 with the limiting block 21. Finally, check whether the sealing strip 33 is tightly fitted to the other parts of the air purifier to ensure there is no air leakage. In this way, the replacement process of the filter element 13 is completed.
