[0021] This utility model provides a filtration device, including a body 101, a filter screen 109, and a disassembly mechanism. The disassembly mechanism includes a fixing ring 115, a mounting ring 108, a cover plate 102, multiple first locking blocks 112, multiple second locking blocks 113, a connecting assembly, a rotating ring 105, multiple telescopic assemblies, and a pressure plate 114. The connecting assembly includes an externally threaded cylinder 104 and an internally threaded cylinder 103. The telescopic assembly includes a telescopic spring 107 and a telescopic rod 106. The mounting ring 108 has multiple first locking grooves 111 below it and multiple second locking grooves 110 above it. The aforementioned solution solves the problem in the prior art where, although the locking scraper can remove impurities from the upper surface of the filter screen 109, impurities still remain inside the holes of the filter screen 109, clogging the holes and causing the device to malfunction.

[0022] In this embodiment, the filter screen 109 is disposed inside the body 101. The fixing ring 115 is fixedly connected to the body 101 and located on the inner sidewall of the body 101. The mounting ring 108 is fixedly connected to the filter screen 109 and located above the fixing ring 115. The cover plate 102 is detachably connected to the body 101 via the connecting assembly and located above the body 101. The rotating ring 105 is disposed below the connecting assembly. Multiple telescopic components are disposed between the rotating ring 105 and the pressure plate 114, with the pressure plate 114 located above the mounting ring 108. When the filter screen 109 needs to be cleaned, the cover plate 102 is opened via the connecting assembly. At this time, the multiple telescopic components return to their original position and extend, removing the pressure plate 114 from the body 101. The body is then tilted... The mounting ring 108 and the filter screen 109 are slid out of the body 101, allowing the filter screen 109 to be removed separately for thorough cleaning. When reinstalling the filter screen 109, the mounting ring 108 and the filter screen 109 are placed inside the body 101, with the mounting ring 108 secured above the fixing ring 115. The cover plate 102 is then installed above the body 101 via the connecting assembly. At this time, the multiple telescopic components are in a retracted state, and the mounting ring 108 is tightly clamped between the clamping plate and the fixing ring 115, thus securing the mounting ring 108 and the filter screen 109. This method allows the filter screen 109 to be disassembled and cleaned, ensuring that the pores of the filter screen 109 remain open and that the device operates normally.

[0023] Furthermore, the external threaded cylinder 104 is fixedly connected to the body 101 and is located above the body 101; the internal threaded cylinder 103 is fixedly connected to the cover plate 102; the internal threaded cylinder 103 is threadedly connected to the external threaded cylinder 104 and is located inside the external threaded cylinder 104.

[0024] Furthermore, the two ends of the telescopic spring 107 are fixedly connected to the rotating ring 105 and the pressure plate 114 respectively, and the two ends of the telescopic rod 106 are fixedly connected to the rotating ring 105 and the pressure plate 114 respectively, and are located inside the telescopic spring 107.

[0025] In this embodiment, when disassembling the filter screen 109, the cover plate 102 and the internal threaded cylinder 103 are rotated. The internal threaded cylinder 103 is pulled out from the external threaded cylinder 104. At the same time, the rotating ring 105 rotates relative to the internal threaded cylinder 103. The plurality of telescopic springs 107 and the plurality of telescopic rods 106 return to their original positions and retract until the pressure plate 114 is removed from the body 101. Then, the body 101 is tilted so that the mounting ring 108 and the filter screen 109 slide out of the body 101, so that the operator can thoroughly clean the filter screen 109. When reinstalling the filter screen 109, the mounting ring 108 and the filter screen 109 are placed on the body 101. Inside the first section, the mounting ring 108 is clamped above the fixing ring 115, bringing the clamping plate into contact with the mounting ring 108. At this time, the cover plate 102 is pressed down and rotated, causing the internal threaded cylinder 103 and the external threaded cylinder 104 to be threadedly connected. Simultaneously, the rotating ring 105 rotates relative to the internal threaded cylinder 103, compressing multiple telescopic springs 107 and multiple telescopic rods 106. The mounting ring 108 is tightly clamped between the clamping plate and the fixing ring 115, thereby fixing the mounting ring 108 and the filter screen 109. The filter screen 109 can be disassembled and cleaned in this way, ensuring that the holes of the filter screen 109 remain open and that the device can operate normally.

[0026] Furthermore, the plurality of first card blocks 112 are fixedly connected to the fixing rings 115, and the plurality of fixing rings 115 are slidably connected to the mounting rings 108 and are respectively located in the plurality of first card slots 111.

[0027] Furthermore, the plurality of second locking blocks 113 are fixedly connected to the pressure plate 114, and the plurality of second locking blocks 113 are slidably connected to the mounting ring 108 and are respectively located in the plurality of second locking slots 110.

[0028] In this embodiment, when installing the filter screen 109, multiple first locking blocks 112 are respectively locked into multiple first locking slots 111, and multiple second locking blocks 113 are respectively locked into multiple second locking slots 110, so that the filter screen 109 will not rotate or misalign during installation and disassembly, thereby improving the structural rationality of the device.

[0029] When disassembling the filter screen 109 using this invention, rotate the cover plate 102 and the internal threaded cylinder 103. The internal threaded cylinder 103 is pulled out from the external threaded cylinder 104. At the same time, the rotating ring 105 rotates relative to the internal threaded cylinder 103. The multiple telescopic springs 107 and the multiple telescopic rods 106 return to their original positions and retract until the pressure plate 114 is removed from the body 101. Then, tilt the body 101 to allow the mounting ring 108 and the filter screen 109 to slide out of the body 101, facilitating a thorough cleaning of the filter screen 109 by the operator. When reinstalling the filter screen 109, place the mounting ring 108 and the filter screen 109 on the body 101. Inside, the mounting ring 108 is clamped above the fixing ring 115, bringing the clamping plate into contact with the mounting ring 108. At this time, the cover plate 102 is pressed down and rotated, and the internal threaded cylinder 103 and the external threaded cylinder 104 are threadedly connected. Simultaneously, the rotating ring 105 rotates relative to the internal threaded cylinder 103, and the multiple telescopic springs 107 and multiple telescopic rods 106 are compressed. The mounting ring 108 is tightly clamped between the clamping plate and the fixing ring 115, thereby fixing the mounting ring 108 and the filter screen 109. The filter screen 109 can be disassembled and cleaned in the above manner, ensuring that the holes of the filter screen 109 remain open and that the device can operate normally.
