[0029] Reference is made below to Figure 1 and Figure 2 describe the exhaust fan moving structure according to an embodiment of the present utility model.

[0030] As Figure 1 and Figure 2 shown, the exhaust fan moving structure according to an embodiment of the present utility model includes a box body 100, a fan 200 and a sliding connection hanging strip 300.

[0031] The box body 100 has an inner cavity. A sliding connection clamping plate 120 is provided on the box body 100, and a sliding connection slot 123 is provided on the sliding connection clamping plate 120; the fan 200 is located in the inner cavity of the box body 100; the sliding connection hanging strip 300 is located outside the box body 100. The sliding connection hanging strip 300 includes a sliding connection edge 320, and the sliding connection edge 320 is clamped into the sliding connection slot 123. The box body 100 can at least move along the extending direction of the sliding connection hanging strip 300 to a first position and a second position.

[0032] For example, as Figure 1 and Figure 2 shown, the box body 100 has an inner cavity, and the fan 200 is located in the inner cavity of the box body 100. A sliding connection clamping plate 120 is provided on the box body 100, and a sliding connection slot 123 is provided on the sliding connection clamping plate 120, that is, the sliding connection clamping plate 120 is equivalent to the box body 100 being fixed. The sliding connection hanging strip 300 is located outside the box body 100. The sliding connection hanging strip 300 includes a sliding connection edge 320, and the sliding connection edge 320 is clamped into the sliding connection slot 123 to realize the connection between the sliding connection hanging strip 300 and the box body 100. Referring to Figure 3 , the box body 100 can at least move along the extending direction of the sliding connection hanging strip 300 to a first position and a second position, that is, the box body 100 is movable relative to the sliding connection hanging strip 300.

[0033] During actual installation, the sliding connection hanging strip 300 is pre-installed at a predetermined exhaust fan installation position, and the specific positions of the first position and the second position are determined according to the actual working requirements of the exhaust fan of the present utility model, which will not be elaborated here.

[0034] Taking the first position as the installation position of the exhaust fan of the present utility model and the second position as the working position of the exhaust fan of the present utility model as an example, after the sliding connection hanging strip 300 is pre-installed, the box body 100 with the fan 200 installed is aligned. Among them, the sliding connection slot 123 on the box body 100 is aligned with the sliding connection edge 320 at the first position of the sliding connection hanging strip 300, so that the sliding connection clamping plate 120 can clamp the sliding connection hanging strip 300, and the box body 100 can be hung on the sliding connection hanging strip 300. Then, by using the characteristic that the sliding connection edge 320 can slide in the sliding connection slot 123, the box body 100 is moved from the first position to the second position, so that the box body 100 reaches the predetermined working position. In this way, the installation of the exhaust fan of the present utility model is completed.

[0035] The above design enables the exhaust fan of the present utility model to be movable after installation, and can control the exhaust fan of the present utility model to move from an easily installable and fixable installation position to a relatively difficult-to-install and fixable working position, making the installation of the exhaust fan more flexible and convenient, and expanding the applicable range of the exhaust fan.

[0036] In some embodiments of the present utility model, referring to Figure 2 , the sliding connection hanging strip 300 includes a hanging strip mounting plate 310, a hanging strip mounting hole 311 is provided on the hanging strip mounting plate 310, and the sliding connection edge 320 is located at the edge position of the hanging strip mounting plate 310. A hanging strip mounting hole 311 is provided on the hanging strip mounting plate 310, and the sliding connection hanging strip 300 is fixedly installed by installing screws in the hanging strip mounting hole 311, making the fixed installation of the sliding connection hanging strip 300 more reliable and also making the sliding connection edge 320 on the sliding connection hanging strip 300 more stable.

[0037] In some specific embodiments of the present utility model, the sliding connection edges 320 are arranged on the upper and lower sides of the hanging strip mounting plate 310 respectively, and the sliding connection clamping plates 120 are also arranged on the upper and lower sides respectively corresponding to the hanging strip mounting plates 310 on both sides of the sliding connection edges 320, further making the installation of the box body 100 on the sliding connection hanging strip 300 more stable.

[0038] In some embodiments of the present utility model, the sliding connection edge 320 includes a first sliding connection edge folding plate 321 and a second sliding connection edge folding plate 322, the second sliding connection edge folding plate 322 is connected to the first sliding connection edge folding plate 321 and the hanging strip mounting plate 310, and the cross-section of the sliding connection edge 320 is in an "L" shape, ensuring that the sliding connection edge 320 is strong and reliable enough.

[0039] In some specific embodiments of the present utility model, a transition inclined plate is arranged between the first sliding connection edge folding plate 321 and the second sliding connection edge folding plate 322, making the processing of the sliding connection edge 320 easier.

[0040] In some embodiments of the present utility model, the sliding connection hanging strip 300 includes a hanging strip end support plate 330 at the end, and the end position of the sliding connection hanging strip 300 is fixed by installing screws on the hanging strip end support plate 330. Equivalently, when the box body 100 is installed on the sliding connection hanging strip 300, the hanging strip end support plate 330 assists in fixing the sliding connection hanging strip 300, ensuring that when the box body 100 is installed on the sliding connection hanging strip 300, the sliding connection hanging strip 300 is not easily loosened due to the turning torque.

[0041] In some embodiments of the present utility model, the sliding connection clamping plate 120 includes a first clamping folding plate 121 and a second clamping folding plate 122, the second clamping folding plate 122 is connected to the first clamping folding plate 121 and the box body 100, and the cross-section of the sliding connection clamping plate 120 is in an "L" shape, making the sliding connection clamping plate 120 more stable and reliable.

[0042] In some specific embodiments of the present utility model, a transition inclined plate is provided between the first clamping and folding plate 121 and the second clamping and folding plate 122, making the processing of the sliding clamping plate 120 easier.

[0043] In some embodiments of the present utility model, an auxiliary pressing strip 400 is provided on the sliding hanging strip 300. A pressing strip mounting hole 411 is provided on the auxiliary pressing strip 400. Screws sequentially pass through the pressing strip mounting hole 411 and the hanging strip mounting hole 311 to fixedly install the auxiliary pressing strip 400 and the sliding hanging strip 300, so as to make the installation of the sliding hanging strip 300 more stable. Since when the box body 100 is installed on the sliding hanging strip 300, the box body 100 directly presses on the sliding edge 320 position of the sliding hanging strip 300, which will cause the sliding hanging strip 300 to bear not only the downward gravity but also a turning force towards the box body 100 direction, easily causing the sliding hanging strip 300 to become loose. And the box body 100 does not directly generate this turning force on the auxiliary pressing strip 400. Therefore, by using the auxiliary pressing strip 400 to assist in fixing the sliding hanging strip 300, the auxiliary pressing strip 400 can avoid loosening due to the pressure of the box body 100, and the auxiliary pressing strip 400 assisting in pressing tightly the sliding hanging strip 300 can make the sliding hanging strip 300 more stable.

[0044] Furthermore, the sliding hanging strip 300 can be made of a material with relatively high elasticity, which is convenient for the docking of the box body 100 and the sliding hanging strip 300. For example, it is made of stainless steel.

[0045] Furthermore, the auxiliary pressing strip 400 can be made of a hard material to make the installation of the sliding hanging strip 300 more stable. For example, it is made of plastic.

[0046] In some embodiments of the present utility model, the auxiliary pressing strip 400 includes a pressing strip mounting plate 410 and a pressing strip folding edge 420. The pressing strip folding edge 420 is located at the edge position of the pressing strip mounting plate 410. The design of the pressing strip folding edge 420 plays a role in strengthening the structural strength of the pressing strip mounting plate 410, making the structure of the auxiliary pressing strip 400 more solid.

[0047] In some embodiments of the present utility model, the auxiliary pressing strip 400 includes a pressing strip end support plate 430 at the end. The end position of the pressing strip end support plate 430 is fixed by installing screws on the pressing strip end support plate 430. Similarly, it can ensure that when the box body 100 is installed on the sliding hanging strip 300, the sliding hanging strip 300 and the auxiliary pressing strip 400 are not easily loosened due to the turning torque.

[0048] In some embodiments of the present utility model, the sliding edge 320 and the hanging strip end support plate 330 on the sliding hanging strip 300 are formed by bending processing, and the pressing strip folding edge 420 and the pressing strip end support plate 430 on the auxiliary pressing strip 400 are also formed by bending processing.

[0049] In some embodiments of the present utility model, a fan support plate 500 is provided on the inner side wall of the box body 100, a fan support protrusion 210 is provided on the fan 200, and the fan support plate 500 is connected to the fan support protrusion 210, facilitating the installation of the fan 200 in the box body 100.

[0050] In some specific embodiments of the present utility model, the fan support plate 500 has an "L" - shaped structure. The fan support plate includes a first fan support plate 510 and a second fan support plate 520. The first fan support plate 510 is connected to the fan support protrusion 210, and the second fan support plate 520 is connected to the inner side wall of the box body 100.

[0051] In some embodiments of the present utility model, referring to Figure 4 , a detachable air outlet member 600 is provided on the box body 100. The air outlet member 600 has a through - hole communicating with the inner cavity of the fan 200. In this way, the air outlet member 600 can be installed when the box body 100 is in the first position on the sliding hanging strip 300, or the air outlet member 600 can be installed when the box body 100 is in the second position, making the installation more flexible.

[0052] In some specific embodiments of the present utility model, an air outlet clamping position 130 is provided on the box body 100, a member clamping edge 610 is provided on the air outlet member 600, and the member clamping edge 610 on the air outlet member 600 is connected to the air outlet clamping position 130 on the box body 100.

[0053] In some embodiments of the present utility model, the air inlet 110 of the box body 100 faces downward, and the air outlet member 600 is located on the side wall on the upper side of the box body 100.

[0054] In some embodiments of the present utility model, referring to Figure 1 , the box body 100 can adopt a small - sized box structure, and the sliding hanging strip 300 only needs to be provided on one side of the box body 100.

[0055] In some embodiments of the present utility model, referring to Figure 5 , the box body 100 can adopt a large - sized box structure, and the sliding hanging strip 300 can be provided on both sides of the box body 100.
