[0020] The utility model is further described below in conjunction with the accompanying drawings.

[0021] Embodiment 1

[0022] In order to solve the problem that when replacing the filter element of the existing filter, it is necessary to open multiple fixing bolts or disassemble other parts, which increases the difficulty and time of replacing the filter element. The process of removing and replacing the filter element is also likely to damage other parts, resulting in increased maintenance costs and reduced user experience. The utility model provides a filter with a quick-replacement filter element, including a shell 1, a shell 1, a filter element 2 is arranged inside the shell 1, a cover body 3 is arranged on the inner side of the upper end of the shell 1, a slidingly connected pressing buckle 13 is arranged on one side of the upper end of the shell 1, an elastic mechanism 32 corresponding to the pressing buckle 13 is arranged at the lower end of the cover body 3, a fixing mechanism 21 cooperating with the elastic mechanism 32 is arranged at the upper end of the filter element 2, a connecting piece 31 is arranged at the lower end of the cover body 3, and the elastic mechanism 32 is arranged on one side of the connecting piece 31 The elastic mechanism 32 includes a round block 33, a shaft body 34 and a spring 35. The shaft body 1 and the connecting piece are arranged at one end of the round block 33. The shaft body 1 passes through the connecting piece 31. The fixing mechanism 21 includes a connecting plate 22, two springs 23 and a shaft body 24. The springs 23 and the shaft body 24 are both on one side of the connecting plate 22. The spring 23 is fixed to the inner side of the filter element 2. When the filter element 2 is removed, the pressing buckle 13 is pressed to make the shaft body 1 34 push the shaft body 24 to move inward, and the limit of the shaft body 24 on the cover body 3 is released, so that the cover body 3 can be removed easily. Then the hand-held handle 25 is extracted to take out the filter element 2 for replacement. An air inlet pipe 14 is provided on one side of the shell 1, and an air outlet pipe 15 is provided at the lower end of the shell 1 to absorb polluted gas and discharge it after filtration.

[0023] Embodiment 2

[0024] On the basis of Example 1, the utility model is provided with a hollow groove 11 at the bottom of the shell 1, and a circular dust box 12 corresponding to it is provided in the hollow groove 11, so that the dust box 12 can be conveniently extracted to clean the dust at the bottom of the shell 1 to prevent excessive dust inside from affecting the filtering effect of the filter. A strip-shaped hand handle 25 is provided on the top of the filter element 2, and a grip 36 is provided on the cover body 3 for convenient holding during replacement. The round block 33 is the same size as the push buckle 13, and a suitable inclined surface is provided at the end close to the shaft body 1 34 and the shaft body 2 24, so that after pressing the push buckle 13, the shaft body 2 24 can be separated from the restriction on the cover body 3 to remove the cover body 3.

[0025] Working principle of this utility model:

[0026] See also Figure 1-4When in use, the second shaft body 24 passes through the empty groove of the connecting piece 31 and is fixed to the cover body 3 under the action of the spring pulling the connecting plate 22. At the same time, the second shaft body 24 abuts against the first shaft body 34 and pushes the pressing buckle 13 outward through the round block 33. When the filter element 2 needs to be replaced, it is only necessary to press the pressing buckle 13. The pressing buckle squeezes the round block 33 to drive the first shaft body 34 to move inward. After the first shaft body 34 pushes the second shaft body 24, the second shaft body 24 is separated from the empty groove under the cover body 3, and the cover body 3 is taken out by the extraction handle 36. Then, the filter element 2 can be extracted and replaced by the hand-held handle 25, which effectively solves the problem of complicated filter element replacement steps.

[0027] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
