[0027] The utility model provides a technical solution:

[0028] Embodiment 1

[0029] Combination Figures 1 to 4 A waste exhaust fan device with the function of simply replacing the fan comprises a wall 3, a mounting mechanism 1 is arranged on the inner side of the wall 3, and a fixing mechanism 2 is arranged inside the mounting mechanism 1.

A clamping strip 1203 is fixedly connected to the outer side of the slide plate 1201, and a groove is provided on the wall 3 corresponding to the position of the clamping strip 1203. The reset component 13 includes a transmission block 1301, which is fixedly connected to the inner side of the slide plate 1201. A compression spring 1302 is arranged on the outer side of the transmission block 1301, and the compression spring 1302 is fixedly connected to the inner side of the slide plate 1201, and the compression spring 1302 is fixedly connected to the slide groove 1202.

[0032] Furthermore: the slide plate 1201, under the action of the compression spring 1302, drives the clamping strip 1203 to always maintain the force of moving inward, so that the compression spring 1302 can keep the clamping strip 1203 retracted into the slide groove 1202 without being affected by external forces, and will not be stuck in the wall 3, thereby reducing the time spent by the staff on disassembling and assembling the fan, so that the staff can easily complete the installation or disassembly of the exhaust fan body 1101.

[0033] Embodiment 2

[0034] See also Figures 1 to 3 and Figure 5 On the basis of the first embodiment, it is further obtained that the fixing mechanism 2 includes a driving component 21 and a transmission component 22 , the driving component 21 is arranged on the front side of the mounting component 11 , and the transmission component 22 is arranged on the rear side of the driving component 21 .

[0035] The driving component 21 includes a fixed screw barrel 2101, which is fixedly connected to the front side of the block 1103, the outer ring of the fixed screw barrel 2101 is fixedly connected with a reinforcing fin 2102, the reinforcing fin 2102 is fixedly connected to the front side of the block 1103, the inner ring of the fixed screw barrel 2101 is threadedly connected with a threaded rod 2103, and the front side of the threaded rod 2103 is fixedly connected with an inner hexagonal rotating block 2104, and the transmission component 22 includes a convex rod 2201, the convex rod 2201 is fixedly connected to the rear side of the threaded rod 2103, the outer ring of the convex rod 2201 is rotatably connected with a rotating cylinder 2202, the outer ring of the rotating cylinder 2202 is fixedly connected with a connecting fin 2203, the outer side of the connecting fin 2203 is fixedly connected with a sliding cylinder 2204, the sliding cylinder 2204 is slidably connected in the block 1103, and the rear end of the sliding cylinder 2204 is an arc surface.

[0036] Furthermore: the staff only needs to use the hexagonal wrench to rotate the inner hexagonal rotating block 2104 to drive the slide cylinder 2204 to move backward to squeeze the clamping strip 1203 outward, so that the clamping strip 1203 is clamped in the wall 3 to complete the fixation of the exhaust fan body 1101. At the same time, the staff only needs to rotate the inner hexagonal rotating block 2104 to drive the slide cylinder 2204 forward to release the force on the clamping strip 1203, so that the clamping strip 1203 retracts into the slide groove 1202 and is no longer connected to the wall 3, which is convenient for work to install or disassemble the exhaust fan body 1101.

[0037] During the actual operation, when the device is used, when the exhaust fan body 1101 needs to be installed, the staff first clamps the exhaust fan body 1101 into the wall 3. When the exhaust fan body 1101 is clamped into the wall 3, the clamping block 1103 is also clamped into the corresponding notch in the wall 3. Then the staff uses a hexagonal wrench to rotate the hexagonal rotating blocks 2104 at the four corners. The rotation of the hexagonal rotating blocks 2104 drives the threaded rod 2103 to rotate. The threaded rod 2103 rotates on the inner circle of the fixed screw barrel 2101 and moves backward. The rod 2103 moves backwards and drives the rotating drum 2202 to move backwards through the protruding rod 2201. The rotating drum 2202 moves backwards and drives the slide 2204 to move backwards through the connecting fin 2203. The slide 2204 moves backwards and contacts the transmission block 1301 to squeeze the transmission block 1301 to move outwards into the slide slot 1202. The transmission block 1301 moves outwards and drives the clamping strip 1203 to move outwards through the slide plate 1201. The clamping strip 1203 moves outwards and is clamped in the wall 3. At this time, the installation of the exhaust fan body 1101 is completed.

[0038] When it is necessary to disassemble the exhaust fan body 1101, the staff rotates the hexagonal turn block 2104 in the reverse direction. It can be seen from the above that the reverse rotation of the hexagonal turn block 2104 drives the slide cylinder 2204 to move forward, and the slide cylinder 2204 moves forward to release the squeezing of the transmission block 1301. At this time, the slide plate 1201 drives the clamping strip 1203 to move inward under the action of the compression spring 1302, and the clamping strip 1203 moves inward and retracts into the slide groove 1202 to break away from the connection with the wall 3. After that, the staff can move the exhaust fan body 1101 forward to complete the disassembly of the exhaust fan body 1101.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
