However, since the existing filter element is generally not retractable, it is inconvenient to replace the filter element, which increases the user's maintenance cost. For this reason, a retractable internal support frame for the filter element is designed. Utility Model Content

The retraction mechanism 3 includes a fixed plate 301 fixedly connected to the outer wall of the circumference of the column 2, and a plurality of inclined grooves 302 are opened at equal distances on the top of the fixed plate 301. A retraction rod 306 is slidably provided on the top of each inclined groove 302, and a first slider 307 and a second slider 308 are fixedly connected to the bottom of each retraction rod 306, and the first slider 307 and the second slider 308 at the bottom of the same retraction rod 306 are slidably connected in the same inclined groove 302, and the top of each retraction rod 306 is close to the side of the column 2. A baffle 309 is fixedly connected, and the baffle 309 and the first slider 307 are coaxial. The first slider 307 can only move along the direction of the inclined groove 302. A rotating disk 303 is provided at the top of the fixed disk 301. A plurality of straight holes 304 that are compatible with the inclined groove 302 are opened at equal distances on the top circumference of the rotating disk 303. Each straight hole 304 is radially distributed along the radial direction of the column 2. Each baffle 309 is slidably connected to the adjacent straight hole 304. A circular hole that is compatible with the column 2 is opened in the middle of the rotating disk 303. A connecting block 305 is fixedly connected to the inner wall of the rotating disk 303. The column 2 is provided with arc holes 201 that are compatible with the connecting block 305 near the top and bottom.

[0025] In this embodiment, the outer sides of the retracting rods 306 on the same side of the two retracting mechanisms 3 are fixedly connected to the same support rod 4 , and the multiple support rods 4 are all perpendicular to the bottom plate 1 .

[0026] In this embodiment, a rotating rod 5 is rotatably sleeved on the middle of the column 2 , and the two connecting blocks 305 are fixedly connected to the outer circumferential wall of the rotating rod 5 . A circular hole matching the rotating rod 5 is opened in the middle of the column 2 .

[0027] In this embodiment, a square rod 501 is fixedly connected to the top of the rotating rod 5, a protrusion 503 is fixedly connected to the top of the square rod 501, a sleeve block 6 is slidably sleeved on the side of the square rod 501, a square hole adapted to the square rod 501 is opened in the middle of the sleeve block 6, and a spring 502 is sleeved at the bottom of the sleeve block 6 of the square rod 501. The setting of the spring 502 ensures that the first limit ring 203 and the second limit ring 601 are in contact when there is no external force.

[0028] In this embodiment, a second limiting ring 601 is fixedly connected to the bottom of the outer circumferential wall of the sleeve 6, and a plurality of grooves are equidistantly arranged on the top of the second limiting ring 601, a sleeve 202 is fixedly connected to the top of the inner circumferential wall of the sleeve 202, and a first limiting ring 203 is fixedly connected to the top of the inner circumferential wall of the sleeve 202, and a plurality of ridges are equidistantly arranged on the bottom of the first limiting ring 203, and the ridges and the grooves are adapted to each other. Through the setting of the ridges and the grooves, in a natural state, in conjunction with the spring 502, the knob 603 will not rotate at will.

[0029] In this embodiment, the top of the sleeve 6 is fixedly connected to a fixed cylinder 602, and the top of the fixed cylinder 602 is fixedly connected to a knob 603. By rotating the knob 603, the operation of the contraction mechanism 3 is controlled.

[0030] Working principle: When in use, pressing the knob 603 causes the second limiting ring 601 to descend and compress, causing the second limiting ring 601 and the first limiting ring 203 to descend, and then rotating counterclockwise, causing the multiple retraction rods 306 to approach one side of the column 2, realizing the retraction of the support rod 4, and then the cylindrical filter element is placed on the outer side of the multiple support rods 4, and then pressing the knob 603 again to separate the second limiting ring 601 and the first limiting ring 203, rotating the knob 603 clockwise, causing the two rotating disks 303 to rotate, and through the setting of the straight hole 304, the blocking rod 309 is pushed to move, the blocking rod 309 and the first slider 307 are coaxial, and the first slider 307 slides on the inclined groove 302, and through the rotation of the rotating disk 303, the multiple retraction rods 306 gradually extend along the inclined groove 302, cooperating with the multiple support rods 4 to support the filter element. The positive and negative rotation of the knob 603 makes it easy to replace the filter element.
