DETAILED DESCRIPTION
[0023] The utility model will be further explained in detail in combination with the drawings and specific embodiments of the present application.
[0024] Referring to the drawings Figure 1 to the drawings Figure 2 It is shown that the present embodiment provides a ceiling fan 10, which comprises a shell 100, a fan wheel 112 and a motor 111. The upper end and the front side of the shell 100 are respectively formed with an air inlet 200 and an air outlet 400. A cover plate 300 is installed at the air inlet 200. The end face of the cover plate 300 is formed with a plurality of mesh holes 301. The mesh holes 301 are arranged to prevent other sundries from entering the inner cavity of the shell 100 on the basis of ensuring normal air inflow.
[0025] Referring to the drawings Figure 2 It is shown that in the present embodiment, an air guide plate 600 is installed in the inner cavity of the shell 100. The upper end and the front side of the air guide plate 600 are respectively formed with openings to correspond to the air inlet 200 and the air outlet 400 on the shell 100. An upper side plate 800 is installed at the top end of the air guide plate 600. Similarly, the upper side plate 800 is also provided with openings so that the air flowing from the air inlet 200 can enter the inner cavity of the air guide plate 600. In some embodiments, in order to better air inflow, an air guide ring 900 is installed at the opening of the upper side plate 800. The inner circle of the air guide ring 900 is a circular arc cross-section structure. In this way, the external air receives less wind resistance during the inflow process.
[0026] Referring to the drawings Figure 2 to the drawings Figure 4 As shown, a lower side plate 700 is installed at the bottom end of the air guide plate 600, and the lower side plate 700 is fixedly mounted on the four side walls of the outer shell 100. For example, in this embodiment, the three outer edges of the lower side plate 700 are respectively formed with folded edges 702, and each folded edge 702 is formed with a screw mounting hole. When the lower side plate 700 is installed, the three sides of the lower side plate 700 are respectively attached to the inner walls of the three corresponding side walls of the outer shell 100, and the lower side plate 700 is fixedly mounted in the inner cavity of the outer shell 100 by screwing screws into the screw mounting holes from the outside of the outer shell 100. At the same time, a gap is formed between the lower side plate 700 and the bottom of the inner cavity of the outer shell 100, that is, the lower side plate 700 does not contact the bottom plate of the inner cavity of the outer shell 100.
[0027] Continue to refer to 3 and Attachment Figure 4 As shown, a motor mounting hole 701 is formed in the center of the lower side plate 700, which runs through from top to bottom. The motor 111 is accommodated in the motor mounting hole 701 and fixedly mounted on the lower side plate 700. By fixing the lower side plate 700 to the side plates around the housing 100, and by not contacting the bottom plate in the inner cavity of the housing 100, the weight of the motor 111 is applied to the lower side plate 700 (the bottom end of the motor 111 does not contact the bottom of the inner cavity of the housing 100), and then evenly applied to the side walls of the housing 100. In addition, the vibration generated by the motor 111 during operation is also applied to the side walls of the housing 100. This solves the problem that the connection between the bottom shell and the surrounding shell panels is prone to loosening and noise due to the weight of the motor 111 and the vibration generated during operation are all concentrated on the bottom plate of the housing 100.
[0028] Refer to the attached Figure 4 As shown, the lower side plate 700 is provided with a plurality of long strip openings 703 spaced apart along the circumferential direction of the outer edge of the motor mounting hole 701. The arrangement of the openings 703 can reduce the vibration transmitted to the housing 100 when the motor 111 is working.
[0029] Refer to the attached Figure 1 To the attached Figure 3 As shown, symmetrically arranged lugs 500 are formed on the side walls of the housing 100 on both sides of the air outlet 400. When the ceiling fan 10 is installed, the housing 100 can be fixed to the installation wall via the lugs 500 thereon. The two lugs 500 can bear greater weight, which helps to increase the load capacity of the motor 111. During operation, the oscillations generated by the motor 111 will be transmitted to the supporting structure such as the housing 100 through the lugs 500. By sharing the weight of the two lugs 500, the weight of the motor 111 can be better dispersed, reducing the damage to the motor 111 caused by the oscillation.
[0030] Refer to the attached Figure 3 and attached Figure 5As shown, the suction fan in the use process, with the inflow air entrained foreign matter (such as dust or other small size sundries) may adhere to the electronic components 113 in the cavity of the shell 100 (such as capacitor), the use performance or life of electronic components 113 caused by the impact, in order to slow down the accumulation of dust sundries on the electronic components 113, the inner cavity of the shell 100 is located above the electronic components is provided with a baffle 110, the existence of the baffle 110, can form a shelter for the electronic components 113 located below, reduce the adhesion of dust or sundries on the electronic components 113.
[0031] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and equivalent technologies, the present application also intends to include these modifications and variations.
