[0017] like Figure 2-3 As shown, the filter installation assembly includes a filter and a wrench 1.

[0018] The filter comprises a cylinder 2 and a filter seat 3 fixed to the bottom of the cylinder 2 and fixedly connected to the cylinder 2. The upper end of the filter seat 3 is open, and its upper end is sleeved with the lower end of the cylinder 2. The filter seat 3 is thick at the top and thin at the bottom, and a plurality of snap-in holes 4 are formed on its outer peripheral surface. A transparent observation plate 5 is sealed and embedded in the snap-in hole 4. The observation plates 5 are evenly distributed on the filter seat 3. The observation plates 5 are sunk in the snap-in hole 4. The outer side surfaces of all the observation plates 5 are extended to form a prism that is thick at the top and thin at the bottom.

[0019] like Figure 1 As shown, the wrench 1 is used for disassembling and assembling the filter seat 3. The wrench 1 includes a gripping plate 6, a disassembling ring 7 connected to the front end of the gripping plate 6, and a plurality of clamping protrusions 8 matching the clamping hole 4 are formed on the inner side wall of the disassembling ring 7. Each clamping protrusion 8 extends in a direction parallel to the axial direction of the disassembling ring 7. When the disassembling ring 7 is inserted into the filter seat 3 from bottom to top and the clamping protrusion 8 is clamped into the clamping hole 4, the disassembling ring 7 rotates around the axial direction of the disassembling ring 7 and drives the filter seat 3 to rotate. Each clamping protrusion 8 is in a cross shape and consists of a symmetrical upper half 81 and a lower half 82. Both the upper half 81 and the lower half 82 are in a convex shape. When the clamping protrusion 8 is clamped into the clamping hole 4, the upper edge of the clamping protrusion 8 fits with the upper edge of the clamping hole 4, and the side edges of the clamping protrusion 8 fit with the side edges of the clamping hole 4 respectively. The distance between the inner side wall of the latching protrusion 8 and the axis of the disassembly ring 7 increases gradually from the middle of the latching protrusion 8 to the upper and lower sides, that is, when the upper half 81 of the latching protrusion 8 is latched with the upper end of the latching hole 4, the inner side wall of the upper half 81 of the latching protrusion 8 is attached to the observation plate 5; when the lower half 82 of the latching protrusion 8 is latched with the upper end of the latching hole 4, the inner side wall of the lower half 82 of the latching protrusion 8 is attached to the observation plate 5.

[0020] A cylinder hexagonal flange 9 is provided on the lower end portion of the filter seat 3, and a nut hole 0 matching the cylinder hexagonal flange 9 is provided on the upper end surface or the lower end surface of the rear end portion of the gripping plate 6. When the nut hole 0 is sleeved on the cylinder hexagonal flange 9, the disassembly ring 7 rotates around the axial direction of the disassembly ring 7, thereby driving the cylinder hexagonal flange 9 to rotate and then driving the filter seat 3 to rotate.

[0021] The utility model has the following two disassembly and assembly methods: 1. Sleeve the nut hole 0 of the wrench 1 on the hexagonal flange 9 of the cylinder at the bottom of the filter seat 3, and rotate the wrench 1 in the direction specified by the arrow mark at the bottom of the cylinder 2 to loosen or tighten the filter seat 3; 2. Sleeve the disassembly and assembly ring 7 of the wrench 1 on the filter seat 3, and rotate the wrench 1 in the direction specified by the arrow mark at the bottom of the cylinder 2 to loosen or tighten the filter seat 3.

[0022] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
