The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0027] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0028] Reference Figure 1-7 , a filtering and purifying device which is convenient for disassembling and replacing a filter screen, comprising a purification box 1, an upper surface of the purification box 1 is fixedly connected with an inlet pipe 2, a side surface of the purification box 1 is fixedly connected with an outlet pipe 3, a sealing door 4 is arranged on the front of the purification box 1, and symmetrically distributed slide grooves 5 are provided on the inner walls of both sides of the purification box 1, and sliders 6 are slidably connected to the inner walls of the slide grooves 5, and a plurality of sliders 6 are arranged in a linear array in groups of two, and a mounting frame 7 is fixedly connected to the opposite surfaces of each group of sliders 6, and a handle is provided on the mounting frame 7, so as to facilitate the movement of the mounting frame 7, and the slide grooves 5 and the sliders 6 cooperate with the mounting frame 7 for stable movement, and the outer surface of the mounting frame 7 contacts the inner wall of the purification box 1, and the upper surface of the mounting frame 7 is provided with symmetrically distributed mounting grooves 8;

[0029] The inner wall of the installation groove 8 is provided with a quick release device, and the quick release device includes a rectangular sleeve 9 , and the lower surface of the rectangular sleeve 9 is fixedly connected to the inner bottom wall of the installation groove 8 .

[0030] The inner wall of the rectangular sleeve 9 is movably sleeved with an elastic plate 91, and the lower surface of the elastic plate 91 is fixedly connected with symmetrically distributed return springs 92, one end of each of the return springs 92 is fixedly connected to the inner bottom wall of the mounting groove 8, and the inner walls of the two rectangular sleeves 9 are movably sleeved with filter frames 93, and the elastic plate 91 cooperates with the elastic force of the return spring 92 to bounce the filter frame 93, thereby facilitating the removal and replacement of the filter frame 93, and the outer surface of the filter frame 93 is movably plugged with the inner wall of the mounting frame 7, and the inner wall of the filter frame 93 is fixedly sleeved with a filter screen 94, and the filter screen 94 has three layers, from top to bottom. The caliber of each filter becomes smaller successively, thereby reducing the burden of a single filter and improving the filtering efficiency. The lower surface of the filter frame 93 is in contact with the upper surfaces of the two elastic plates 91 respectively. The front and back sides of the rectangular sleeve 9 are provided with symmetrically distributed mounting openings 95. The inner wall of the mounting opening 95 is hinged with a swing plate 96 through a pin shaft. A rolling wheel 97 is provided at the lower end of the swing plate 96. The outer surfaces of multiple rolling wheels 97 are in rolling contact with the upper surface of the filter frame 93. The rolling wheels 97 play a role in reducing the friction with the surface of the filter frame 93 when the swing plate 96 swings. A pressing block 98 is movably sleeved on the inner wall of the rectangular sleeve 9.

[0031] The lower surface of the pressing block 98 is fixedly connected to a connecting rod 99, and a movable block 910 is fixedly sleeved on the outer surface of the connecting rod 99. The inner wall of the movable block 910 is hinged with a symmetrically distributed swing rod 911, and one end of the swing rod 911 is hinged with a support 912 through a pin shaft. One side surface of the support 912 is fixedly connected to a side surface of the swing plate 96. The lifting and lowering movement of the movable block 910 is achieved through the cooperation between the swing rod 911 and the support 912, which drives the swing plate 96 to swing. One end of the connecting rod 99 is fixedly connected to a lifting block 913, and the lower surface of the lifting block 913 is fixedly connected to a support spring 914. The elastic force of the support spring 914 drives the lifting block 913 to reset and move upward, and one end of the support spring 914 is fixedly connected to the inner bottom wall of the rectangular sleeve 9.

[0032] By setting up a quick-release device, the filter frame 93 and the filter 94 can be quickly installed and disassembled. Compared with the traditional rotational connection limit of the screw and the threaded barrel, the problem of repeated rotation of the threaded barrel causing a long time and easy loss is avoided, thereby greatly improving the efficiency of disassembly, assembly and replacement of the filter 94, reducing the downtime, and further improving the filtering efficiency.

[0033] Working principle: Step 1, when removing the filter frame 93, first open the sealing door 4, then pull the installation frame 7 through the handle on the installation frame 7, so that the filter frame 93 is pulled out of the purification box 1 through the cooperation of the slide groove 5 and the slider 6, and then the two pressing blocks 98 are pressed synchronously, and the downward movement of the pressing block 98 drives the movable block 910 to move downward through the connecting rod 99, and the downward movement of the movable block 910 drives the swing plate 96 to swing through the cooperation of the swing rod 911 and the support 912. The swing of the swing plate 96 causes one end of the swing plate 96 to swing and be stored in the installation opening 95. At this time, the limit of the swing plate 96 on the filter frame 93 disappears, and the elastic force of the reset spring 92 bounces the filter frame 93 upward through the elastic plate 91, so that it is out of the installation frame 7, and then release the pressing block 98 to take out the filter frame 93;

[0034] Step 2: When replacing the filter screen 94, the filter screen frame 93 is pressed downward through the guide of the rectangular sleeve 9, and the filter screen frame 93 will squeeze the swing plate 96. After the swing plate 96 is squeezed, the support 912 and the swing rod 911 cooperate to drive the movable block 910 to move downward. The downward movement of the movable block 910 drives the support spring 914 to shrink through the lifting block 913. When the swing plate 96 swings and is stored in the installation opening 95, the filter screen frame 93 moves downward to fit the elastic plate 91. At this time, the filter screen frame 93 is continued to be pressed downward, so that the elastic plate 91 drives the return spring 92 to shrink.

[0035] Step three, when the filter frame 93 drops to a certain position, the elastic force of the support spring 914 drives the movable block 910 to rise through the cooperation of the lifting block 913 and the connecting rod 99, and the rising movement of the movable block 910 drives the swing plate 96 to swing in the opposite direction through the swing rod 911 and the support 912. At this time, the pressure on the filter frame 93 is released, and the filter frame 93 is driven to rise by the elastic force of the reset spring 92 and the elastic plate 91. When the filter frame 93 rises and moves to contact the rolling wheel 97 at one end of the swing plate 96, it stops moving. At this time, the filter 94 in the filter frame 93 is limited and installed through the swing plate 96.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
