Multiple groups of protective gaskets 6 are provided, and another group of protective gaskets 6 is fixedly connected to the right end of the guard plate 7. The two groups of protective gaskets 6 can respectively support the left and right sides of the ceramic filter element 1. The top of the lower sleeve 3 is provided with a fixing component 4 for connecting the upper sleeve 2 and the lower sleeve 3. The fixing component 4 includes a protrusion 41. The bottom end of the protrusion 41 is fixedly connected to the top of the lower sleeve 3. When the upper sleeve 2 and the lower sleeve 3 are fitted together, the protrusion 41 can penetrate the upper sleeve 2. The right end of the upper sleeve 2 is provided with an unlocking component 5 for releasing the fixation between the upper sleeve 2 and the lower sleeve 3.

[0032] Reference Figure 2 - Figure 4 The fixing assembly 4 also includes a fixing block 43 for fixing the protrusion 41. The fixing block 43 is slidably connected to the front end of the upper sleeve 2 near the top position. The right end of the protrusion 41 is provided with a fixing groove 42 for accommodating the fixing block 43. The fixing groove 42 and the fixing block 43 are adapted. When the fixing block 43 is inserted into the fixing groove 42, the protrusion 41 will be fixed and cannot move up and down. At the same time, the lower sleeve 3 will also be fixed to the bottom end of the upper sleeve 2. The right end of the fixing block 43 is fixedly connected to drive the fixing block 43 to move The movable connecting plate 44 and the fixed blocks 43 are provided with multiple groups. Another group of fixed blocks 43 is fixedly connected to the left end of the connecting plate 44. When the connecting plate 44 moves left and right, the two groups of fixed blocks 43 will be driven to move synchronously. The right end of the connecting plate 44 is fixedly connected to a fixed spring 45 for pushing the connecting plate 44. The right end of the fixed spring 45 is fixedly connected to the inner wall of the upper sheath 2. The fixed spring 45 will always push the connecting plate 44 to the left, and the connecting plate 44 will push the fixed block 43 to insert it into the interior of the protrusion 41.

[0033] Reference Figure 3 - Figure 5The unlocking assembly 5 includes a connecting rod 54 for driving the connecting plate 44 to move. The left end of the connecting rod 54 is fixedly connected to the right end of the connecting plate 44. The right end of the connecting rod 54 passes through and is slidably connected to the right end of the upper sheath 2. The connecting plate 44 can be driven to move by pulling the connecting rod 54. The right end of the connecting rod 54 is provided with a dial block 52 for facilitating the operator to move the connecting rod 54. The dial block 52 is set to be L-shaped. The upper end of the L-shaped dial block 52 can be used to mobilize the dial block 52 to move. The inner wall of the dial block 52 is provided with a plastic block 53 for driving the positioning block 56 to move. The plastic block 53 is a long strip of plastic with elastic deformation capability. The front end of the plastic block 53 is fixedly connected with a positioning block 56 for fixing the shift block 52. The inner wall of the upper sheath 2 is provided with a positioning groove 55 for accommodating the positioning block 56. The positioning groove 55 and the positioning block 56 are adapted to each other. When the positioning block 56 is inserted into the interior of the positioning groove 55, the shift block 52 will be fixed and cannot move to the left. The inner wall of the positioning groove 55 is slidably connected with an unlocking block 51 for pushing the positioning block 56. By pushing the unlocking block 51, the positioning block 56 can be squeezed out of the interior of the positioning groove 55.

[0034] Working principle: During installation, the top end of the ceramic filter element 1 is inserted into the upper sleeve 2, and the bottom end is inserted into the lower sleeve 3. Since the upper sleeve 2 and the lower sleeve 3 are designed to be separated, they can be installed in an upper and lower manner, avoiding the problem of possible friction between the inner wall of the integrated protective sleeve and the outer wall of the ceramic filter element 1 during installation, causing blockage of holes. At the same time, the protective pad 6 and protective plate 7 inside the lower sleeve 3 can support the ceramic filter element 1, reducing the contact area between the filter element and the inner walls of the upper sleeve 2 and the lower sleeve 3, and further reducing friction.

[0035] When the upper cover 2 and the lower cover 3 need to be fixed, the upper cover 2 is fitted with the lower cover 3. At this time, the protrusion 41 will pass through the upper cover 2. Under the action of the fixing spring 45, the fixing spring 45 always pushes the connecting plate 44 to the left. The connecting plate 44 drives the two groups of fixing blocks 43 to move, so that the fixing block 43 is inserted into the fixing groove 42 at the right end of the protrusion 41, thereby fixing the protrusion 41 and realizing the fixed connection between the upper cover 2 and the lower cover 3.

[0036] When disassembly is required, the L-shaped upper end of the shift block 52 is moved to drive the connecting rod 54 to move, and the connecting rod 54 drives the connecting plate 44 to move, so that the fixing block 43 is disengaged from the fixing groove 42. At the same time, the plastic block 53 on the inner wall of the shift block 52 drives the positioning block 56 to move. When the positioning block 56 is stuck in the positioning groove 55, the shift block 52 is fixed and cannot move to the left. At this time, the upper cover 2 and the lower cover 3 can be separated. When the fixation of the shift block 52 needs to be released, the unlocking block 51 is pushed. The unlocking block 51 squeezes the positioning block 56 to make it disengage from the inside of the positioning groove 55, and the shift block 52 is reset under the action of the fixing spring 45.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
