Description

Technical Field

[0001] This utility model relates to the field of fans, and in particular to a motor mounting structure for a vertical fan. Background Technology

[0002] The vertical fan includes a support rod, a fan body, a blade cover, and fan blades. The fan body is rotatably connected to the support rod, and the blade cover and fan blades are located on the front side of the fan body. The fan body includes a fan housing, a motor housing, a motor, and a rotating assembly. The motor is located inside the motor housing and is connected to the front side of the inner side of the fan housing via the motor housing. The motor housing includes a front cover and a rear cover, which, when fitted together, better secure the motor within the fan body.

[0003] However, this design involves two parts: the fan housing front cover and the motor housing front cover, both of which are relatively thick and therefore costly. If the fan housing front cover and the motor housing front cover could be combined, production costs, assembly complexity, and transportation costs could be reduced. Therefore, a simple, low-cost, and easy-to-assemble motor mounting structure for vertical fans is needed. Utility Model Content

[0004] The main objective of this invention is to provide a motor mounting structure for a vertical fan that is simple in structure, low in production cost, and easy to assemble.

[0006] The fan housing includes a fan housing body and a fan housing front cover. The motor housing has a motor housing cavity inside. One end of the motor housing has a motor housing opening that communicates with the motor housing cavity. Multiple motor housing connection holes are arranged around the motor housing opening. The motor housing is screwed to the fan housing front cover through the motor housing connection holes.

[0007] The motor is fixedly mounted between the front cover of the fan housing and the motor housing.

[0008] Preferably, it also includes a connecting bearing;

[0009] The front cover of the fan housing is provided with a front cover through hole, and a front cover connecting groove is provided around the front cover through hole on the inner side of the front cover of the fan housing. The connecting bearing is disposed in the front cover connecting groove, and the first output shaft on the front side of the motor passes through the connecting bearing and the front cover through hole and is connected to the fan blade.

[0010] Preferably, the inner cavity of the motor housing is provided with a plurality of limiting support seats for supporting and limiting the motor. The limiting support seats cooperate with the front cover of the fan housing to limit the motor between the front cover of the fan housing and the motor housing.

[0011] Preferably, it further includes a swing assembly, wherein a motor housing through hole is provided on the rear side of the motor housing, and the second output shaft on the rear side of the motor passes through the motor housing through hole and meshes with the swing assembly.

[0012] The beneficial effects of the motor mounting structure of the vertical fan of this utility model are as follows:

[0013] 1. Compared to existing designs, the design utilizes the front cover of the fan housing as the front cover of the motor housing, thereby reducing structural complexity and production costs.

[0014] 2. Compared to existing designs, it is more conducive to fan heat dissipation. Attached Figure Description

[0020] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0021] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0022] Reference Figures 1 to 4 An embodiment of the motor mounting structure of the vertical fan of this utility model is proposed:

[0023] A motor mounting structure for a vertical fan includes a fan housing 1, a connecting bearing, a swing assembly 4, a motor housing 2, and a motor 3.

[0024] The fan housing 1 includes a fan housing body 12 and a fan housing front cover 11. A front cover connecting slot is provided on the rear side of the fan housing front cover 11, and a body connecting block is provided on the front side of the fan housing body 12. The fan housing body 12 is snapped onto the fan housing front cover 11 by the cooperation of the front cover connecting slot and the body connecting block.

[0025] The fan housing front cover 11 has a through hole 111 in the middle. A front cover connecting groove 112 surrounds the through hole 111 on the inner side of the fan housing front cover 11, and a connecting bearing is disposed within the front cover connecting groove 112. Multiple front cover connecting holes 113 surround the outer side of the front cover connecting groove 112. The motor housing 2 has an inner cavity, and one end of the motor housing 2 has an opening communicating with the inner cavity. Motor housing connecting holes 21, which are adapted to the front cover connecting holes 113, surround the opening on the motor housing 2. The front cover connecting holes 113 and the motor housing connecting holes 21 are connected by screws, thereby fixing the motor housing 2 and the fan housing front cover 11 together.

[0026] The inner cavity of the motor housing is provided with multiple limiting support seats 22 for supporting and limiting the motor 3. The limiting support seats 22 cooperate with the front cover 11 of the fan housing to limit the motor 3 between the front cover 11 of the fan housing and the motor housing 2. The first output shaft 31 on the front side of the motor 3 passes through the connecting bearing and the through hole 111 of the front cover and is connected to the fan blade.
