[0026] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0027] Please refer Figures 1-8 As shown, the present utility model provides an integrated ceiling duct exhaust fan 100, including: a volute 1, a bottom plate 2, an impeller assembly 3, and a shock-absorbing cotton sheet 4.

[0028] The volute 1 includes a volute body 11, an air outlet 12 formed in the volute body 11, and a junction box 13 formed on the peripheral side of the volute body 11.

[0029] The bottom plate 2 includes a rectangular bottom plate body 21 covering the volute body 11 and detachably connected to the volute body 11, an air inlet 22 penetrating through the bottom plate body 21, four limiting walls 23 protruding from the side of the bottom plate body 21 away from the volute body 11, and a plurality of receiving grooves 24 recessed from the side of the bottom plate body 21 away from the volute body 11.

[0030] The volute body 11 and the bottom plate body 21 jointly enclose a receiving space. The four limiting walls 23 are respectively located on the four sides of the air inlet 22, and are arranged in parallel in pairs, and two adjacent limiting walls 23 are perpendicular to each other, that is, the four limiting walls 23 jointly enclose a rectangular structure arranged around the air inlet 22.

[0031] A plurality of the receiving grooves 24 are respectively located outside the limiting walls 23 and extend from the peripheral side of the bottom plate body 21 to the limiting walls 23. That is to say, the limiting walls 23 are not arranged at the outermost edge of the bottom plate body 21, but are at a certain distance from the outermost edge, and the receiving grooves 23 are arranged in this distance interval of the bottom plate body 21. The distance between two limiting walls 23 arranged in parallel matches the distance between two keels 10 for supporting the bottom plate 2, so that the keels 10 abut against the outside of the limiting walls 23, thereby forming a limit on the bottom plate 2 and restricting the movement of the bottom plate 2 along the keels 10. The other two limiting walls 23 arranged in parallel are also arranged in the same way, so that the four sides of the bottom plate 2 are clamped by the keels to form a horizontal restriction.

[0032] The shock-absorbing cotton sheet 4 is arranged in the receiving groove 24 and protrudes from the side of the bottom plate body 21 away from the volute 1.

[0033] During installation, place two sides of the bottom plate 2 between two parallel keels 10, and rotate the other two sides between another two parallel keels 10, so that two groups of opposite limiting walls 23 are clamped between the two groups of keels 10 and respectively abut against the inner sides of the two groups of keels 10 to form a limit, while the shock-absorbing cotton sheet 4 is padded between the bottom plate 2 and the keels 10 to form an elastic buffer and increase friction, so that the bottom plate 2 will not move on the keels 10, eliminating the accessory buckle and the cumbersome installation buckling steps in the prior art, realizing simple and convenient installation, and reducing the use of accessories, thereby saving production costs. Finally, the panel 20 is snap-connected to the side of the keel 10 away from the bottom plate 2 and is arranged opposite to the bottom plate 2.

[0034] More preferably, the bottom plate 2 further includes limiting and strengthening walls 25 protruding and extending away from the volute body 11 from both ends of each limiting wall 23, which are used to further protect and strengthen the movement restriction of the bottom plate 2 and improve the stability after installation.

[0035] In this embodiment, the detachable connection mode formed by the volute 1 and the bottom plate 2 can improve the installation efficiency and has better assembly reliability. Specifically, the bottom plate 2 further includes a plurality of self-locking holes 26 penetrating through the bottom plate body 21. The plurality of self-locking holes 26 are arranged around the air inlet 22 and are located inside the four limiting walls 23, that is, the self-locking holes 26 are located within the range surrounded by the four limiting walls 23. The volute 1 further includes a plurality of self-locking arms 14 formed on the side wall of the volute body 11. The plurality of self-locking arms 14 respectively match with the plurality of self-locking holes 26 to form a detachable engagement. The number of the self-locking holes 26 is 8 - 12, and the number of the self-locking arms 14 is 8 - 12. In this embodiment, both the self-locking holes 26 and the self-locking arms 14 are 9, and their numbers are set according to specific needs.

[0036] The wind wheel assembly 3 is installed and fixed inside the volute body 11, and the power cord of the wind wheel assembly 3 penetrates through the side wall of the volute body 11 and extends into the junction box 13.

[0037] The volute 1 further includes a wire groove 15 formed by the depression on the side of the volute body 11 close to the bottom plate 2 and a wire pressing plate 16 fixed to the volute body 11. The wire groove 15 extends from the position of the wind wheel assembly 3 to the junction box 13. One end of the wire pressing plate 16 is fixed to the volute body 11, and the other end of the wire pressing plate 16 straddles the wire groove 15. Thus, the power cord 30 of the wind wheel assembly 3 is directly received in the wire groove 15 and is limited by the wire pressing plate 16. This structural setting replaces the way of setting a power cord cover plate in the prior art, thereby reducing the mold cost of components and improving the installation efficiency.

[0038] The bottom plate 2 further includes a main tension rib 27 located on one of the diagonals of the bottom plate body 21 and an arc-shaped secondary tension rib 28. The main tension rib 27 extends from the air inlet 22 to a set of diagonal positions of the bottom plate body 21, and the secondary tension rib 28 extends along the circumference of the air inlet 22. The settings of the main tension rib 27 and the secondary tension rib 28 increase the structural strength of the bottom plate 2, keep the air inlet 22 balanced, prevent deformation and tipping, maintain the best air inlet state, and improve the stability of the integrated ceiling duct ventilating fan 100.

[0039] Compared with the prior art, in the integrated ceiling duct ventilation fan of the present utility model, four limiting walls are formed to protrude from the side of the bottom plate body away from the volute body, and a plurality of receiving grooves are formed to be recessed from the side of the bottom plate body away from the volute body; the four limiting walls are respectively located on the four sides of the air inlet, and are arranged in parallel in pairs and perpendicular to each other adjacent to each other; the plurality of receiving grooves are respectively located on the outer periphery of the limiting walls and extend from the peripheral side of the bottom plate body to the limiting walls. Thus, during installation, the bottom plate is placed between two parallel keels, so that two opposite limiting walls are clamped between the two keels and respectively abut against the inner sides of the two keels to form a limit, while the shock-absorbing cotton sheet is padded between the bottom plate and the keel to form an elastic buffer, eliminating the accessory buckle and the cumbersome installation buckling steps of the prior art, realizing simple and convenient installation, reducing the use of accessories, and thus saving production costs; in addition, through the design of the wire groove, the power cord cover plate in the prior art is cancelled, and the power cord of the impeller assembly is directly introduced into the junction box through the wire groove, improving the installation efficiency, reducing the power cover plate component, and further saving the accessory cost.

[0040] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
