[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figures 1-8The present invention discloses an external filter frame, including a mesh frame 1. A connecting groove 11 is provided on the inner side of the mesh frame 1. A connecting seat 2 is rotatably installed in the connecting groove 11. The connecting seat 2 is connected to the filter frame 3 through a connecting component. The connecting component includes a connecting rod 31 provided on the inner side of the filter frame 3. A slot 21 is provided on the connecting seat 2. The connecting rod 31 is adapted to the slot 21 and is sleeved in the slot 21 of the connecting seat 2. A fixing component is provided on the mesh frame 1. The fixing component includes a fixing block 4 installed on the mesh frame 1. After the filter frame 3 is installed, the fixing block 4 is adapted to the other end of the filter frame 3 to fix the filter frame 3.

[0031] When installing the filter frame 3, the connecting rod 31 is fitted into the slot 21 of the connecting seat 2. The filter frame 3 drives the connecting seat 2 to rotate a certain angle, and the connecting seat 2 rotates synchronously to fit the connecting groove 11. One end face of the filter frame 3 is in contact with the outer end face of the mesh frame 1. At this time, the fixing block 4 fits with the other end of the filter frame 3, fixing the filter frame 3 onto the mesh frame 1. When disassembling the filter frame 3, the fixing block 4 is moved, and after rotating the filter frame 3, the connecting rod 31 is disengaged from the slot 21, and the filter frame 3 can be directly disassembled. The filter frame 3 is rotated and fitted by the connecting seat 2, which is convenient. The installation and removal of the filter frame 3 solves the drawback of the inconvenience of traditional built-in filter installation and removal. At the same time, through the adaptation of the connecting seat 2 and the connecting groove 11, it is easy to hide the connecting seat 2 inside the connecting groove 11 when the filter frame 3 is installed. The connecting seat 2 facilitates the rotation and installation of the filter frame 3, and avoids the edge of the filter frame 3 from contacting the mesh frame 1 during the rotation and installation and removal process, which affects the installation. The hidden connection structure further ensures the airtightness of the connection of the filter frame 3, and avoids the situation where the sliding groove of the filter frame 3 is easy to stick to the slide, which affects the installation and removal of the filter frame 3.

[0032] The connecting assembly also includes a first connecting rod 5 mounted on the connecting groove 11. An L-shaped first connecting plate 51 and a second connecting plate 52 are rotatably mounted on the first connecting rod 5. The first connecting plate 51 and the second connecting plate 52 are mutually compatible. A first connecting hole 511 is provided on the first connecting plate 51, and a second connecting rod 512 is mounted on the first connecting hole 511. A first sliding groove 111 is provided on the upper and lower end faces of the connecting groove 11. First sliders 5121 are mounted on the upper and lower ends of the second connecting rod 512, and the first sliders 5121 are compatible with the first sliding groove 111. A second connecting hole 521 is provided on the second connecting plate 52, and a third connecting rod 522 is mounted on the second connecting hole 521. Second sliders 5221 are mounted on the upper and lower ends of the third connecting rod 522. The connecting seat 2 has a hollow interior design, and the upper and lower end faces of the connecting seat 2 are provided with first connecting holes 511 and 5121. The second slide groove 22 is adapted to the second slider 5221. The other end of the first connecting plate 51 needs to be rotatably connected to the connecting seat 2, and the other end of the second connecting plate 52 needs to be rotatably connected to the connecting groove 11. It should be noted that the directions of the first slide groove 111 and the second slide groove 22 are deviated from the direction of the first connecting rod 5 and are inward. In the initial state, the first slider 5121 slides in the first slide groove 111 and drives the first connecting plate 51 to rotate. At the same time, the second slider 5221 slides in the second slide groove 22 and drives the second connecting plate 52 to rotate. After the connecting seat 2 is offset inward by a certain angle, it rotates synchronously. After the connecting seat 2 drives the filter frame 3 to rotate, it separates from the outer end face of the mesh frame 1, which is convenient for installation and disassembly. It avoids the connecting seat 2 from hitting the mesh frame 1 during rotation and affecting the rotation. It is convenient for the filter frame 3 to rotate during installation and disassembly.

[0033] A baffle 12 is provided on the side of the mesh frame 1 that is biased towards the connecting seat 2. After the filter frame 3 is installed, the inner end face is in contact with the outer end face of the baffle 12 to ensure the airtightness of the connection during the installation of the filter frame 3.

[0034] The fixing assembly also includes a sliding hole 13 on the mesh frame 1. The fixing block 4 is slidably installed in the sliding hole 13. The filter frame 3 is provided with a fixing hole 32. The fixing block 4 extends out and is provided with a connecting shaft 41. The other end of the connecting shaft 41 is adapted to the fixing hole 32. The fixing block 4 is connected to the sliding hole 13 through an elastic element 42. The elastic element 42 is preferably a spring. The elastic element 42 is always in a compressed state. A square groove 131 is provided on the front side of the sliding hole 13. A push part 43 is provided on the fixing block 4. The push part 43 slides in the square groove 131. When fixing the filter frame 3, the elastic element 42 drives the fixing block 4 to slide in the sliding hole 13, so that the connecting shaft 41 is adapted to the fixing hole 32. At this time, the filter frame 3 is fixedly installed on the mesh frame 1. When disassembling the mesh frame 1, the push part 43 is pushed by hand to move in the direction of the elastic element 42, so that the connecting shaft 41 is disassembled from the fixing hole 32. At this time, the fixing of the filter frame 3 can be released.

[0035] A fixing frame 33 is installed on the filter frame 3, and a filter screen 34 is installed on the filter frame 3. The filter screen 34 is located in front of the fixing frame 33.

[0036] In this invention, when installing the filter frame 3, the connecting rod 31 is sleeved in the slot 21. Rotating the filter frame 3 causes the first slider 5121 to slide in the first groove 111, driving the first connecting plate 51 to rotate. The second slider 5221 slides in the second groove 22, driving the second connecting plate 52 to rotate. The connecting seat 2 is then offset inwards by a certain angle and rotated synchronously. Pushing the pusher 43 aligns the connecting shaft 41 with the fixing hole 32. When disassembling the filter frame 3, pushing the pusher 43 disengages the connecting shaft 41 from the fixing hole 32. Rotating the filter frame 3 disengages the connecting rod 31 from the slot 21, allowing the filter frame 3 to be directly removed from the mesh frame 1. The filter frame 3 is detached from the top and rotated via the connecting seat 2, which facilitates the installation and removal of the filter frame 3. This solves the problem of inconvenient installation and removal of traditional built-in filters. At the same time, the adapter between the connecting seat 2 and the connecting groove 11 makes it easy to hide the connecting seat 2 inside the connecting groove 11 when the filter frame 3 is installed. The connecting seat 2 facilitates the rotational installation of the filter frame 3 and avoids the edge of the filter frame 3 from contacting the mesh frame 1 during the rotational installation and removal process, which would affect the installation. The hidden connection structure further ensures the airtightness of the connection of the filter frame 3 and avoids the situation where the sliding groove of the filter frame 3 is easy to stick to the slide, which would affect the installation and removal of the filter frame 3.
