[0039] Combine the following Figure 1-Figure 6 The utility model is described as a filter screen installation structure, which comprises: a mounting bracket 10 , a limiting groove 21 and a limiting seat 22 .

[0040] The mounting bracket 10 is used to mount the filter 30. The first end of the mounting bracket 10 is provided with a plug-in connector 11, and the second end of the mounting bracket 10 is provided with an elastic limiting portion 12. The limiting groove 21 is provided on the inner side wall of the air inlet grille 20 and / or the air outlet grille, and the limiting groove 21 is suitable for plugging and matching with the plug-in connector 11. The limiting seat 22 is provided on the inner side wall of the air inlet grille 20 and / or the air outlet grille, and the limiting seat 22 is provided with a limiting hole 23. When the elastic limiting portion 12 is in a compressed state, the elastic limiting portion 12 can pass through the limiting hole 23; when the elastic limiting portion 12 is in a free state, the elastic limiting portion 12 is limited to one side of the limiting hole 23, and the mounting bracket 10 is limited to the other side of the limiting hole 23.

[0041] Specifically, the mounting bracket 10 is in the form of a frame, on the inner side of which the filter 30 is fixed. According to the position where the filter 30 needs to be installed, a limiting groove 21 and a limiting seat 22 are installed on the inner wall of the air inlet grille 20 and / or the air outlet grille to fix the mounting bracket 10.

[0042] During the assembly process, the connector 11 is first inserted into the limiting groove 21, and then the elastic limiting part 12 is compressed by external force, and the elastic limiting part 12 is passed through the limiting hole 23. Finally, the elastic limiting part 12 is released, and the elastic limiting part 12 is restored to a free state under the action of its elastic restoring force, and the elastic limiting part 12 is limited to one side of the limiting hole 23, and the mounting bracket 10 is located on the other side of the limiting hole 23, thereby realizing the limited installation of the mounting bracket 10 and ensuring the fixation of the mounting bracket 10. When the mounting bracket 10 needs to be removed and the filter 30 needs to be replaced, the elastic limiting part 12 is compressed by external force, and the elastic limiting part 12 is removed from the limiting hole 23, and finally, the connector 11 is pulled out of the limiting groove 21, that is, the removal of the mounting bracket 10 is completed.

[0043] It is understandable that the limiting seat 22 and the limiting groove 21 should be located at both ends of the air inlet grille 20 and / or the air outlet grille. In this way, when the connector 11 of the mounting bracket 10 is inserted into the limiting groove 21 to limit one end thereof, the other end of the mounting bracket 10 can be limited by the cooperation of the elastic limiting portion 12 and the limiting hole 23, thereby ensuring the fixing of the mounting bracket 10, without the need to fasten the fixed points one by one by fasteners as in the prior art, thereby improving the assembly efficiency. In addition, the connector 11 and the limiting groove 21 are arranged in pairs, and the elastic limiting portion 12 and the limiting seat 22 are also arranged in pairs to ensure that they can cooperate with each other.

[0044] The utility model provides a filter installation structure, which includes: a mounting bracket 10, a limiting groove 21 and a limiting seat 22; the mounting bracket 10 is used to install a filter 30, a plug-in connector 11 is provided at the first end of the mounting bracket 10, and an elastic limiting portion 12 is provided at the second end of the mounting bracket 10; the limiting groove 21 is provided on the inner side wall of the air inlet grille 20 and / or the air outlet grille, and the limiting groove 21 is suitable for plugging and matching with the plug-in connector 11; the limiting seat 22 is provided on the inner side wall of the air inlet grille 20 and / or the air outlet grille, and a limiting hole 23 is provided on the limiting seat 22. When the elastic limiting portion 12 is in a compressed state, the elastic limiting portion 12 can pass through the limiting hole 23; when the elastic limiting portion 12 is in a free state, the elastic limiting portion 12 is limited on one side of the limiting hole 23, and the mounting bracket 10 is located on the other side of the limiting hole 23. The utility model provides a filter screen installation structure, in which the installation bracket 10 is inserted into the limit groove 21 through the plug-in component 11, and the elastic limit portion 12 is used to limit the cooperation with the limit hole 23 to achieve the fixation of the filter screen 30 and the installation bracket 10. It does not need to open holes and is simple to assemble, which reduces assembly time and improves assembly efficiency. It is not easy to fall off, thereby improving safety.

[0045] In one embodiment of the present invention, one end of the connector 11 inserted into the limiting groove 21 forms an elastic portion 111. In this embodiment, the end of the connector 11 that is plugged into the limiting groove 21 forms the elastic portion 111. When the connector 11 is inserted into the limiting groove 21, the elastic portion 111 will be squeezed, and the plugging is flexible and not easy to be damaged.

[0046] In one embodiment of the utility model, a hollow structure 112 is formed on the connector 11, and the hollow structure 112 is arranged close to the elastic part 111. By constructing the hollow structure 112 on the connector 11, the hollow structure 112 is close to the insertion end of the connector 11, so that the thickness of the insertion end can be reduced, so that the elastic part 111 has a certain elasticity. When the connector 11 is inserted, it is easier to be squeezed and compressed due to the small thickness of the insertion end, thereby forming the elastic part 111. Of course, an elastic pad can also be arranged at the insertion end to achieve the effect of the elastic part 111, so as to reduce the damage caused by the collision during the plug-in. Specifically, the connector 11 adopts a plug-in board structure, and the plug-in board is hollowed out to form the hollow structure 112.

In this embodiment, the telescopic end of the elastic buckle can perform telescopic movement under the action of elasticity, and when an external force is applied to compress it, its length is sufficient to pass through the limiting hole 23. After the external force is removed, the telescopic end is reset, and its length is greater than the limiting hole 23, and is stuck on one side of the limiting hole 23, thereby realizing the limiting fixation of the mounting bracket 10.

[0048] In one embodiment of the utility model, the elastic buckle includes: a sleeve, an elastic member and a locking pin. One end of the elastic member is connected to the sleeve; one end of the locking pin extends from the sleeve and is connected to the other end of the elastic member. In this embodiment, the sleeve is a hollow structure 112, one end of the locking pin extends into the sleeve through the elastic member, and the other end extends from the sleeve. The locking pin is squeezed by external force, the elastic member is compressed, and the elastic member is reset when the external force is removed. The elastic buckle provided in this embodiment has a simple structure and is easy to process.

[0049] In one embodiment of the utility model, the filter screen installation structure further includes: a mounting plate 13, the mounting plate 13 is fixed on the outer wall of the mounting bracket 10, and the mounting plate 13 can pass through the limiting hole 23, and the elastic limiting portion 12 is fixed on the mounting plate 13. In this embodiment, by arranging the mounting plate 13 on the outer wall of the mounting bracket 10, the elastic limiting portion 12 is installed, and the elastic limiting portion 12 protrudes from the outer wall of the mounting bracket 10. When the mounting bracket 10 is assembled in place, the mounting plate 13 is located in the limiting hole 23, so that the edges of the elastic limiting portion 12 and the mounting bracket 10 are respectively located on both sides of the limiting hole 23.
