[0027] Next, refer to Figure 1 and Figure 2 to describe the quick disassembly and assembly structure of an exhaust fan according to an embodiment of the present utility model.

[0028] As Figure 1 and Figure 2 shown, the quick disassembly and assembly structure of an exhaust fan according to an embodiment of the present utility model includes a box body 100, a fan 200, and a plug-in member 300.

[0029] The box body 100 has an inner cavity, the lower side of the box body 100 has an installation opening 110, and the side of the box body 100 is provided with a plug-in hole 120; the fan 200 is located in the inner cavity of the box body 100; the plug-in member 300 includes a first plug board 310, a middle board 320, and a second plug board 330. The middle board 320 is connected to the first plug board 310 and the second plug board 330. The first plug board 310 is inserted into the plug-in hole 120 and extends outside the box body 100, and the second plug board 330 abuts against the edge of the installation opening 110 of the box body 100 and extends outside the box body 100. Refer to Figure 3 , the first plug board 310 and the second plug board 330 clamp the fixed point 400 at a predetermined installation position.

[0030] For example, as Figure 1 and Figure 2As shown in the figure, the box body 100 has an inner cavity as a box body, and an installation opening 110 is provided on the lower side of the box body 100. The fan 200 is located in the inner cavity of the box body 100, and the fan 200 can be installed into the box body 100 through the installation opening 110. Moreover, the installation opening 110 can also serve as the air inlet of the exhaust fan in the embodiment of the present utility model.

[0031] A plug-in hole 120 is provided on the side of the box body 100. The plug-in member 300 includes a first plug board 310, a middle board 320, and a second plug board 330. The middle board 320 is connected to the first plug board 310 and the second plug board 330. The first plug board 310 is inserted into the plug-in hole 120 and extends outside the box body 100. The second plug board 330 abuts against the edge of the installation opening 110 of the box body 100 and extends outside the box body 100. That is, the plug-in member 300 is connected to the box body 100 through the first plug board 310, and at the same time, the second plug board 330 assists in clamping the edge position of the installation opening 110 of the box body 100.

[0032] During actual installation, refer to Figure 3 , first install the fan 200 into the box body 100, then carry and lift the box body 100 together with the fan 200 to the predetermined installation position, and then the plug-in member 300 can be installed. Insert the first plug board 310 of the plug-in member 300 into the plug-in hole 120 and make the second plug board 330 abut against the installation opening 110 of the box body 100. When installing the plug-in member 300, make the first plug board 310 and the second plug board 330 extend outside the box body 100 and clamp the fixed point 400 at the predetermined installation position, so that the box body 100 can be temporarily fixed. Then the worker can easily screw to fix the box body 100 to complete the final installation step of the exhaust fan in the embodiment of the present utility model.

[0033] It can be imagined that the specific shape of the fixed point 400 depends on the situation of the predetermined installation position. For example, if the predetermined installation position of the exhaust fan is an opening on the ceiling, the fixed point 400 is the edge position of the opening; if the predetermined installation position of the exhaust fan is an installation station on the production line, the fixed point 400 is the buckle position on the installation station that can clamp the plug-in member 300. And so on, which will not be listed one by one here.

[0034] In some specific embodiments of the present utility model, refer to Figure 1 , an air outlet 130 is provided on the box body 100, corresponding to the air outlet of the fan of the fan 200, and serves as the air outlet of the exhaust fan in the embodiment of the present utility model.

[0035] In some embodiments of the present utility model, a box body fixing plate 140 is provided on the box body 100. That is, after the box body 100 is temporarily fixed by the plug-in member 300, the box body 100 can be fixed by screwing on the box body fixing plate 140.

[0036] It can be conceived that the position of the box fixing plate 140 can be determined according to the installation position of the exhaust fan in the embodiments of the present utility model.

[0037] In some embodiments of the present utility model, referring to Figure 2 , the middle plate 320 is located inside the box body 100. That is, when installing the plug-in connector 300, the middle plate 320 is made to abut against the inner wall of the box body 100 as much as possible, so that the plug-in connector 300 is not easily dropped out.

[0038] In some embodiments of the present utility model, the middle plate 320 is of a straight plate structure, and the plug-in connector 300 is in a "Π" shape, which is easy to process and is beneficial to improving the manufacturing production efficiency.

[0039] In some embodiments of the present utility model, the middle plate 320 is of an arc-shaped plate structure, and the plug-in connector 300 is in a "U" shape, so that the first plug plate 310 and the second plug plate 330 are more elastic by using the material elasticity of the middle plate 320, and the second plug plate 330 can fit more tightly against the installation opening 110 of the box body 100.

[0040] In some specific embodiments of the present utility model, the first plug plate 310 is of a straight plate structure, and the installation opening 110 is a linear through-hole structure, which not only ensures that the first plug plate 310 is more stable after being inserted into the plug hole 120, but also ensures that the first plug plate 310 is sufficiently stable when it extends out of the box body 100 and is stuck in the predetermined installation position.

[0041] In some specific embodiments of the present utility model, the second plug plate 330 is of a straight plate structure, which not only ensures that the second plug plate 330 is more stable when it abuts against the installation opening 110 of the box body 100, but also ensures that the second plug plate 330 is sufficiently stable when it extends out of the box body 100 and is stuck in the predetermined installation position.

[0042] In some specific embodiments of the present utility model, chamfered corners 350 are provided at the corner positions of the first plug plate 310 and the second plug plate 330.

[0043] In some embodiments of the present utility model, mounting holes 341 are provided on the first plug plate and the second plug plate 330. That is, after temporarily fixing the box body 100 through the plug-in connector 300, the box body 100 can be fixed by screwing through the mounting hole 341 on the second plug plate 330 and passing through the mounting hole 341 on the first plug plate 310.

[0044] In some embodiments of the present utility model, bosses 340 are provided on the first plug plate and the second plug plate 330, and the mounting holes 341 are located on the bosses 340, which can improve the structural strength of the position of the mounting holes 341.

[0045] Furthermore, the boss 340 is in a frustum shape.

[0046] In some embodiments of the present utility model, referring to Figure 1 , Figure 3 , the plug-in connector 300 is located below the fan 200 to ensure that the fan 200 does not affect the installation of the plug-in connector 300 and reserve a sufficiently large installation space for the plug-in connector 300.

[0047] In some embodiments of the present utility model, a fan mounting plate 210 is provided on the lower side of the fan 200, and the inner wall of the box body 100 is connected to the fan mounting plate 210 by screws, which is convenient for the installation of the fan 200.

[0048] In a further embodiment of the present utility model, a support plate 220 is provided on the lower side of the fan 200, and the side surface of the support plate 220 abuts against the inner wall of the box body 100, so that after the fan 200 is installed in the box body 100, the fan 200 can be ensured to be more stable and reliable.

[0049] Furthermore, the support plate 220 is in a "U" shape.

[0050] The other components and operations of the exhaust fan according to the embodiments of the present utility model are known to those of ordinary skill in the art and will not be described in detail herein.
