[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the sake of illustration and convenience of description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0020] like Figure 1-4As shown, the technical solution of the utility model provides a filter element protection mechanism, comprising a detachably connected upper cavity 1, a lower cavity 2, an upper buffer mechanism and a lower buffer mechanism respectively located in the upper cavity 1 and the lower cavity 2, and a fixing mechanism for fixing the upper cavity 1 and the lower cavity 2. The upper cavity 1 and the lower cavity 2 form a sealed storage space 3, and the filter 4 is placed in the storage space 3. The upper buffer mechanism and the lower buffer mechanism both include side buffers and top buffers.

[0021] After the upper cavity 1 and the lower cavity 2 are separated, the filter element 4 is first placed in the lower cavity 2, and then the upper cavity 1 is connected to the lower cavity 2 to form a sealed storage space 3, so as to achieve sealed protection for the filter element 4 and prevent dust in the air from contaminating the filter element 4. In this solution, the side buffer and the top buffer are respectively arranged on the side and the top of the upper cavity 1 and the lower cavity 2. After the upper cavity 1 and the lower cavity 2 are combined, the side buffer and the top buffer can achieve protection for the side and the top of the filter element, and can achieve effective protection for the filter element in the case of shaking or slight impact. At the same time, this protective mechanism is easy to disassemble and assemble.

[0022] The side buffer includes a plurality of spherical buffer blocks 5, which are evenly distributed in the circumferential direction, and the side surfaces of the filter element are in contact with the spherical buffer blocks 5 after the filter element is placed. The top buffer includes an annular buffer sheet 6, and the top and bottom surfaces of the filter element are in contact with the annular buffer sheet 6 after the filter element is placed. The spherical buffer blocks 5 and the annular buffer sheet 6 are both made of deformable materials, such as rubber.

[0023] The spherical buffer block 5 is embedded in the upper cavity 1 and the lower cavity 2, and is arranged circumferentially to achieve all-round protection of the filter element side. After the filter element is placed, it is located between the spherical buffer blocks 5. When it hits, the spherical buffer block 5 deforms to buffer and avoids damage to the filter element. The annular buffer sheet 6 on the top protects the upper and lower surfaces of the filter element, and its protection principle is similar to that of the spherical buffer block 5.

[0024] The fixing mechanism includes a fixing rod 8 fixedly connected to the lower cavity 2 and a fixing sleeve 9 threadedly connected to the fixing rod 8. A clearance hole 7 is provided in the middle of the upper cavity 1, and the fixing rod 8 is arranged through the clearance hole 7. A limiting plate 10 is provided on the outer periphery of the fixing sleeve 9. When the fixing sleeve 9 is fixed to the fixing rod 8, the limiting plate 10 is pressed and contacted with the outer surface of the upper cavity 1.

[0025] A limiting groove 11 is provided on the top of the lower cavity 2, and the bottom of the upper cavity 1 is inserted into the limiting groove 11. After the upper cavity 1 and the lower cavity 2 are assembled, the fixing rod 8 passes through the clearance hole 7, and the fixing sleeve 9 is fixed to the threaded part of the top of the fixing rod 8. In the process of the fixing sleeve 9 being screwed into the clearance hole 7, after being rotated into place, the limiting plate 10 is pressed against the outer surface of the upper cavity 1 to achieve limiting, thereby completing the fixing of the upper cavity 1 and the lower cavity 2. The above fixing method facilitates the removal of the filter element without the need for disassembly with the help of an external disassembly structure.

[0026] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
