[0029] Example 1 Please see Figure 1-3 The present invention provides the following technical solution: Specifically, it refers to a filter snap-fit ​​structure, including a Y-shaped housing 1 and a filter cartridge 2 detachably installed inside the Y-shaped housing 1; a snap-fit ​​assembly 3 for fixing the filter cartridge 2 to the Y-shaped housing 1, symmetrically installed between the inner walls of the Y-shaped housing 1; and a guide assembly 4, which works in conjunction with the snap-fit ​​assembly 3 for further fixing the filter cartridge 2 to the Y-shaped housing 1.

[0030] The specific application of this embodiment is as follows: When installing the filter cartridge 2, the filter cartridge 2 is inserted into the Y-shaped housing 1. The guide component 4 automatically guides the filter cartridge 2 into alignment, ensuring accurate positioning between the filter cartridge 2 and the Y-shaped housing 1. Simultaneously, the snap-fit ​​component 3 automatically snaps the filter cartridge 2 into place during insertion, achieving rapid fixation. For disassembly, simply press the snap-fit ​​component 3, and the filter cartridge 2 will pop out under the influence of the guide component 4 and gravity. This embodiment, by setting the snap-fit ​​component 3 and the guide component 4, achieves rapid assembly and disassembly of the filter cartridge 2, avoiding the alignment difficulties of traditional threaded connections and significantly improving maintenance efficiency.

[0031] Example 2 Please see Figure 1-5 This second embodiment is an improvement on the first embodiment as follows: Specifically, the Y-shaped housing 1 includes a main flow channel 5 and an auxiliary flow channel 6 connected to the main flow channel 5; the filter cartridge 2 is detachably installed on the inner circumferential side of the auxiliary flow channel 6.

[0032] The inner wall of the auxiliary channel 6 is symmetrically provided with grooves 7; the inner wall of the auxiliary channel 6 is symmetrically provided with arc-shaped grooves 8 between the inner walls of the auxiliary channel 6 and the main channel 5; a U-shaped groove 9 is provided between the grooves 7 and the arc-shaped grooves 8.

[0033] The snap-fit ​​assembly 3 includes a trapezoidal snap-fit ​​block 31; a connecting spring 32 is fixed to the bottom surface of the trapezoidal snap-fit ​​block 31; the other end of the connecting spring 32 is fixedly connected to the bottom surface of the slide groove 7.

[0034] The bottom surface of the trapezoidal block 31 is fixedly connected to a U-shaped rod 33; the U-shaped rod 33 is slidably disposed inside the U-shaped groove 9; an arc-shaped plate 34 is fixed to the other end of the U-shaped rod 33; the arc-shaped plate 34 is slidably engaged with the arc-shaped groove 8.

[0035] A specific application of this embodiment is as follows: When the filter cartridge 2 is inserted into the auxiliary flow channel 6, the outer wall of the filter cartridge 2 abuts against the inclined surface of the trapezoidal locking block 31, pushing the trapezoidal locking block 31 to move along the slide groove 7 into the slide groove 7, thus compressing the connecting spring 32; when the filter cartridge 2 reaches the predetermined position, the restoring force of the connecting spring 32 pushes the trapezoidal locking block 31 to reset, so that the bottom surface of the trapezoidal locking block 31 abuts against the end face of the filter cartridge 2, forming a firm fixation. At the same time, the U-shaped rod 33 and the arc-shaped plate 34 slide along the trapezoidal locking block 31 in the U-shaped groove 9 and the arc-shaped groove 8, moving and abutting against the outer wall of the filter cartridge 2, further fixing the filter cartridge 2. This embodiment, by designing the locking assembly 3, enables the filter cartridge 2 to effectively prevent loosening and displacement under fluid impact, improving the impact resistance and reliability of the connection between the filter cartridge 2 and the Y-shaped housing 1.

[0036] Example 3 Please see Figure 2-3 , Figure 6This embodiment three is an improvement on the first embodiment as follows: Specifically, the guide component 4 includes a guide groove 41; the guide groove 41 is symmetrically opened between the inner walls of the auxiliary flow channel 6; a slider 42 is slidably arranged in the guide groove 41; a reset spring 43 fixedly connected to the slider 42 is fixedly fixed on the bottom surface of the guide groove 41.

[0037] The outer peripheral side of the filter cartridge 2 is fixed with a guide block 44 that slides in cooperation with the guide groove 41; the guide block 44 is in movable contact with the slider 42.

[0038] The inner wall of the main channel 5 is fixed with a flow guide plate 10 that movably abuts against the filter cartridge 2.

[0039] The auxiliary flow channel 6 is connected to a detachable end cap 11 by fastening bolts at its end.

[0040] One specific application of this embodiment is as follows: During the installation of the filter cartridge 2, the guide block 44 on the filter cartridge 2 slides along the guide groove 41, pushing the slider 42 to compress the return spring 43, providing buffering and precise guidance; when the filter cartridge 2 is fully inserted, the guide block 44 and the slider 42 are pressed together under the return force of the return spring 43, further enhancing the stability of the connection between the filter cartridge 2 and the Y-shaped housing 1 under the combined action of the snap-fit ​​assembly 3 and the guide assembly 4. The flow guide plate 10 optimizes the distribution of fluid in the main channel 5, reducing local impact on the filter cartridge 2 and extending the filter life. When it is necessary to disassemble the filter cartridge 2, simply press the trapezoidal snap-fit ​​block 31, so that the trapezoidal snap-fit ​​block 31 is pressed into the slide groove 7, and the filter cartridge 2 is ejected under the action of the slider 42 and the return spring 43, thereby completing the disassembly process. This embodiment further improves the accuracy and stability of the connection between the filter cartridge 2 and the Y-shaped housing 1 through the linkage design of the snap-fit ​​assembly 3 and the guide assembly 4.
