DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See Figure 1 、 Figure 2 、 Figure 4 A blower housing includes a first housing 100 and a second housing 200 which are divided along an air outlet direction. The first housing 100 is provided with an air inlet cover 101, and the second housing 200 is provided with a motor mounting hole 201. The first housing 100 and the second housing 200 are connected by fasteners. The first housing 100 and the second housing 200 are both made of plastic, wherein the plastic is a new polymer composite material, referred to as thermosetting plastic, specifically SMC or BMC. SMC and BMC have the advantages of high strength and strong corrosion resistance, which can ensure the structural strength of the blower housing. At the same time, dividing the blower housing into the first housing 100 and the second housing 200 along the air outlet direction can facilitate manufacturing and installation, and the stability of the assembly of the first housing 100 and the second housing 200 can be ensured by fasteners.

[0027] See Figure 2 、 Figure 4A bracket 400 is provided at the bottom of the blower housing. The bracket 400 includes a first bracket 103 positioned on the first housing 100 and a second bracket 203 positioned on the second housing 200. The first housing 100 and the first bracket 103 are integrally manufactured, while the second housing 200 and the second bracket 203 are integrally supported. A first through-hole 104 is provided on the first housing 100, and a first blind hole 204 is provided on the second housing 200. The fastener includes a first self-tapping screw inserted through the first through-hole 104 and into the first blind hole 204, thereby securing the first housing 100 to the second housing 200. A second through-hole 105 is provided on the first bracket 103, and a second blind hole 205 is provided on the second bracket 203. The first bracket 103 and the second bracket 203 are secured by a second self-tapping screw inserted through the second through-hole 105 and into the second blind hole 205. The first shell 100 also includes a first air outlet section 102, and the second shell 200 also includes a second air outlet section 202. When the first shell 100 and the second shell 200 are fixed, the first air outlet section 102 and the second air outlet section 202 are combined to form an air outlet 300. A limiting ring 310 is provided on the outer wall of the air outlet 300, which can provide a locking position for the pipeline connected to the air outlet 300, thereby facilitating the connection between the pipeline and the air outlet 300.

[0028] See Figure 3 、 Figure 5 、 Figure 6 、 Figure 7A snap-fit ​​structure is also provided between the first shell 100 and the second shell 200. The first shell 100 includes a first splicing surface 106, and the second shell 200 includes a second splicing surface 206. When the first shell 100 and the second shell 200 are combined, the first splicing surface 106 and the second splicing surface 206 are in contact with each other. The snap-fit ​​structure includes a first snap-fit ​​member 120 and a first snap-fit ​​groove 130 provided on the first splicing surface 106, and a second snap-fit ​​member 220 and a second snap-fit ​​groove 230 provided on the second splicing surface 206. When the first shell 100 and the second shell 200 are combined, the first snap-fit ​​member 120 is embedded in the second snap-fit ​​groove 230, and the second snap-fit ​​member 220 is embedded in the first snap-fit ​​groove 130. At the same time, a slot 110 is provided on the first splicing surface 106, recessed in a direction away from the second housing 200. A first recessed portion 111 is provided on the slot 110, extending in a direction away from the second housing 200. A first clip 120 is fixed within the slot 110 and positioned corresponding to the first recessed portion 111. The space enclosed by the first clip 120 and the first recessed portion 111 constitutes the first snap slot 130. The slot 110 is provided along the contour of the first splicing surface 106, and a convex edge 210 is provided on the second splicing surface 206, which is provided along the contour of the second housing 200. The convex edge 210 can be inserted into the slot 110, thereby merging the first housing 100 and the second housing 200. A second recessed portion 211 is provided on the convex edge 210 and is recessed toward the center of the second shell 200 . At the same time, the second clip 220 is fixed at a position on the convex edge 210 corresponding to the position of the second recessed portion 211 . The space enclosed by the second clip 220 and the second recessed portion 211 is the second clip groove 230 .

[0029] The size of the blower is related to its power. The housing of a blower with a power below 100W is smaller, so a set of snap-fit ​​structures on the blower housing can meet the assembly requirements. In this case, the snap-fit ​​structure is located in the middle of the top of the blower housing. Together with the fastener fixing structure consisting of the first through hole 104, the first blind hole 204 and the first self-tapping screw, it fixes the first housing 100 to the housing to ensure the stability of the overall structure. When the power of the blower is above 120W, the housing needs to be larger. In this case, two sets of snap-fit ​​structures need to be provided. The two sets of snap-fit ​​structures are respectively provided on both sides of the blower housing in the vertical direction to ensure the stability of the structure.

[0030] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
