[0029] Embodiment 2: please refer to Figs. 1-3 , the upper end outer wall of the lower shell 8 is movably connected with the upper shell 1, the upper end outer wall of the upper shell 1 is fixedly connected with the limiting plate 2, the upper end outer wall of the upper shell 1 is provided with the first communication groove 3, the upper end outer wall of the upper shell 1 is provided with the second communication groove 4, the lower end outer wall of the upper shell 1 is movably connected with the filter screen body 5, the outer wall of both sides of the filter screen body 5 is fixedly connected with a connecting block 6, the filter screen body 5 is movably connected with the inner wall of one side of the connecting groove 9 opened on the lower shell 8 through the connecting block 6, and is limitedly connected through the upper shell 1, the slot hole 7 is opened on the connecting block 6, one side of the bolt 12 is connected with the first communication groove 3 opened on the upper shell 1, the pressing block 118 is connected with the second communication groove 4 opened on the upper shell 1, and the slot hole 7 opened on the connecting block 6 is connected with the bolt 12.

[0030] In this embodiment, the upper end of the lower shell 8 is provided with a connecting groove 9 on the outer wall on both sides, the upper shell 1 is connected to the upper end of the outer wall of the lower shell 8, the filter screen body 5 is arranged between the upper shell 1 and the lower shell 8, and one connecting block 6 is fixedly connected to each side of the filter screen body 5. The connecting block 6 can be connected to the connecting groove 9 on the upper end of the outer wall of the lower shell 8. At this time, the filter screen body 5 can be limited by the upper shell 1 and the lower shell 8, but because the filter screen body 5 will be affected by external force during filtering, it cannot be effectively fixed by relying on the clamping action of the upper shell 1 and the lower shell 8. Therefore, the first communication groove 3 is arranged on the upper shell 1, the slot hole 7 is arranged on the connecting block 6, and the first communication groove 3 is connected to the slot hole 7. At this time, the latch 12 can be inserted through the first communication groove 3 and the slot hole 7 in turn, and the latch 12 can be connected to the latch slot 13 through the clamping block 115. Thus, the filter screen body 5 can be fixed, and the deviation can be avoided. The upper end of the pressing block 118 is connected to the second communication groove 4 arranged on the upper shell 1. Therefore, when the pressing block 118 is pressed through the second communication groove 4, the filter screen body 5 can be disassembled. The limiting plate 2 is fixedly connected to the inner wall of the upper shell 1 and the lower shell 8 on one side. The limiting plate 2 is close to the two sides of the filter screen body 5, so that the limiting plate 2 can limit the filter screen body 5.

[0031] As shown in Figs. 1-5 The design is based on the quick release mechanism and the fixing and disassembling operation of the filter screen body 5. The upper end of the outer wall of the lower shell 8 is provided with a mounting groove 10, and the quick release mechanism 11 is arranged in the groove. The quick release mechanism 11 includes a first spring 111 and a second spring 116, and the two springs provide necessary elastic support for the system.

[0032] The first spring 111 and the second spring 116 are fixedly connected to the inner wall bottom end of the mounting groove 10 through a first support plate 112 and a second support plate 117 respectively. Through the connecting shaft 114, the movable block 113 maintains a relative position with the two support plates. When the latch 12 is inserted and acts on the second support plate 117, the second spring 116 is compressed, the movable block 113 is deviated, the clamping block 115 is connected to the latch slot 13, and the position between the upper shell 1 and the lower shell 8 is fixed. At this time, the latch 12 locks the combination of the upper shell 1 and the lower shell 8, and ensures the stability of the structure.

[0033] If the upper shell 1 needs to be disassembled, the pressing block 118 can compress the first spring 111 through the action of the first support plate 112, causing the movable block 113 to deviate in the opposite direction, and the clamping block 115 is disconnected from the latch slot 13. At this time, the latch 12 can be easily taken out, so that the locking between the upper shell 1 and the lower shell 8 is released, allowing the user to easily disassemble the upper shell 1.

[0034] In addition, the filter screen body 5 is designed to be fixed between the upper shell 1 and the lower shell 8 through the connecting groove 9 and the connecting block 6. However, due to external force during the filtering process, the filter screen may be offset. Therefore, the system is provided with the first communication groove 3 on the upper shell 1, and the connecting block 6 is also provided with the corresponding groove hole 7. The plug-in pin 12 can pass through the communication grooves, cooperate with the clamping block 115 and the clamping groove 13, and firmly fix the filter screen body 5, so as to avoid displacement of the filter screen body 5 during operation.

[0035] In order to facilitate the disassembly of the filter screen, the pressing block 118 is also clamped with the second communication groove 4 of the upper shell 1. When the pressing block 118 is extruded, the filter screen body 5 can be easily disassembled, and then the filter screen is replaced or maintained. The existence of the limiting plate 2 ensures that the filter screen body 5 will not deviate from the predetermined position during disassembly or installation, effectively preventing the structure from being unstable due to asymmetric force.

[0036] The overall design realizes the convenience of quick disassembly, filter screen fixation and maintenance through the cooperation of spring, clamping mechanism and sliding structure, and improves the operability and maintenance efficiency of the equipment.

[0037] It should be noted that in this paper, the relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations. Moreover, the term "includes", "contains" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.
