Description

Technical Field

[0001] This utility model relates to the field of filter element technology, and in particular to a filter element that is easy to disassemble. Background Technology

[0002] A filter element consists of a filter element cap and a filter element body. After a period of use, the filter element body needs to be cleaned or replaced, thus requiring frequent disassembly of the filter element cap and filter element body. Currently, the filter element cap and filter element body are connected by threads, which makes disassembly and assembly inconvenient and inefficient. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a filter element that is easy to disassemble, in view of the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] A filter element that is easy to disassemble includes a filter element cap and a filter element body. The upper end face of the filter element body is provided with a guide groove in the radial direction. The side wall of the filter element body is provided with a locking hole, which communicates with the guide groove. A pair of locking plates that slide opposite each other are slidably disposed in the guide groove. The upper end face of the locking plates is provided with a driving pin. The inner side of the filter element cap is provided with a pair of arc-shaped grooves. The driving pin is slidably disposed in the arc-shaped grooves. When the filter element cap is rotated, the driving pin slides along the arc-shaped grooves, thereby driving the locking plates to slide along the guide grooves and the locking hole.

[0006] In a preferred embodiment, a fixed post is provided at the center of the upper end face of the filter element cylinder, and a rotating groove is provided on the inner side of the filter element cap, with the fixed post movably fitted inside the rotating groove.

[0007] In a preferred embodiment, the guide groove extends through the fixed column.

[0008] A preferred embodiment is that the outer side of the filter element cap is provided with a rotating handle.

[0009] The easily disassembled filter element provided by this embodiment of the invention has at least the following beneficial effects: the filter element cap rotates and closes with the filter element cylinder. When the filter element cap is rotated in one direction, the drive pin rotates along the arc-shaped groove in one direction, and a pair of locking plates slide along the guide groove and move away from each other. When the outer end of the locking plate slides into the locking hole, the filter element cap and the filter element cylinder lock together. When the filter element cap is rotated in another direction, the drive pin rotates along the arc-shaped groove in the other direction, and a pair of locking plates slide along the guide groove and move closer to each other. When the outer end of the locking plate slides out of the locking hole, the filter element cap and the filter element cylinder open. Therefore, locking and opening the filter element cap and the filter element cylinder is relatively convenient, improving the efficiency of disassembly and assembly, and facilitating the cleaning of the filter element cylinder.

[0010] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0015] To illustrate the ideas and objectives of this application, the following description will be provided in conjunction with the accompanying drawings and specific embodiments.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," "left," "right," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0017] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] like Figures 1 to 4As shown, this application embodiment provides a filter element that is easy to disassemble, including a filter element cap 10 and a filter element cylinder 20. The upper end face of the filter element cylinder 20 is provided with a guide groove 21 in the radial direction. The side wall of the filter element cylinder 20 is provided with a locking hole 22, which communicates with the guide groove 21. A pair of relatively sliding locking pieces 30 are slidably disposed in the guide groove 21. The upper end face of the locking piece 30 is provided with a driving pin 31. The inner side of the filter element cap 10 is provided with a pair of arc-shaped grooves 11. The driving pin 31 is slidably disposed in the arc-shaped grooves 11. When the filter element cap 10 is rotated, the driving pin 31 slides along the arc-shaped grooves 11, thereby driving the locking piece 30 to slide along the guide groove 21 and the locking hole 22.

[0019] like Figures 1 to 4 As shown, the filter element cap 10 and the filter element cylinder 20 are rotatably closed. When the filter element cap 10 is rotated in one direction, the drive pin 31 rotates along the arc groove 11 in one direction, and a pair of locking plates 30 slide along the guide groove 21 and move away from each other. When the outer end of the locking plate 30 slides into the locking hole 22, the filter element cap 10 and the filter element cylinder 20 are locked together. When the filter element cap 10 is rotated in another direction, the drive pin 31 rotates along the arc groove 11 in the other direction, and a pair of locking plates 30 slide along the guide groove 21 and move closer to each other. When the outer end of the locking plate 30 slides out of the locking hole 22, the filter element cap 10 and the filter element cylinder 20 are opened. Therefore, locking and opening the filter element cap 10 and the filter element cylinder 20 is relatively convenient, and cleaning the filter element cylinder 20 is also convenient.

[0020] like Figures 1 to 4 As shown, a fixing post 23 is provided at the center of the upper end face of the filter element cylinder 20, and a rotating groove 12 is provided on the inner side of the filter element cap 10. The fixing post 23 is movably sleeved in the rotating groove 12. When the filter element cap 10 rotates, the filter element cap 10 rotates along the fixing post 23, and the fixing post 23 plays a role in fixing and guiding.

[0021] like Figures 1 to 4 As shown, the guide groove 21 penetrates the fixed column 23.

[0022] like Figures 1 to 4 As shown, the fixed column 23 does not affect the mutual movement of the pair of locking plates 30. When the filter element cap 10 is rotated in one direction, the pair of driving pins 31 drive the pair of locking plates 30 to move away from or closer to each other, so that the filter element cap 10 and the filter element cylinder 20 are locked or opened, which facilitates the cleaning of the filter element cylinder 20.

[0023] like Figures 1 to 4 As shown, the outer side of the filter element cap 10 is provided with a rotating handle 13. The rotating handle 13 facilitates the rotation of the filter element cap 10.

[0024] The above are specific embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
