Description

Technical Field

[0001] This utility model relates to the field of fans, and in particular to an outdoor fan. Background Technology

[0002] For outdoor fans, the requirements for waterproofing are higher than those for indoor fans due to the demands of the outdoor environment. Current designs often incorporate ventilation holes on the side of the motor housing to improve lifespan and power output, allowing direct cooling. However, this design is clearly unsuitable for outdoor fans. Therefore, there is a need for an outdoor fan that is simple in structure, has excellent heat dissipation, strong waterproofing, and is more convenient for outdoor use. Utility Model Content

[0003] The main purpose of this utility model is to provide an outdoor fan that has a simple structure, good heat dissipation, strong waterproof capability, and is more convenient for outdoor use.

[0004] This utility model proposes an outdoor fan, including a fan housing, a motor, an impeller, and a duct connector;

[0005] The fan housing has a working chamber on its inner side, the impeller is disposed in the working chamber, one side of the working chamber protrudes outward from the fan housing to form a drive chamber inside the fan housing, a housing connection boss is formed on the outside of the fan housing, and the motor is disposed in the drive chamber;

[0006] The outer bottom of the housing connecting boss is provided with a housing boss through hole. The air duct connector is fixedly connected to the fan housing and covers the outer side of the housing boss through hole. The air duct connector is L-shaped. The bottom of the air duct connector is located inside the bottom of the housing connecting boss. The end of the air duct connector is provided with an air duct connector inlet that communicates with the housing boss through hole and faces the fan housing.

[0007] By setting through holes in the housing boss, the motor can draw air in through the housing boss through holes in addition to the traditional air inlet holes, thereby improving the heat dissipation effect of the fan. By setting air duct connectors, the reduction in waterproof performance caused by setting through holes in the housing boss can be effectively avoided.

[0008] Preferably, the fan housing has an air inlet on the side opposite to the housing connecting boss, and the fan housing has an air outlet on the side of the fan housing.

[0009] Preferably, it further includes a support base, which is disposed at the bottom of the fan housing and screwed to the fan housing. The support base is provided with a support base connecting groove adapted to the air duct connector, and the bottom of the support base connecting groove is provided with a support base connecting groove through hole adapted to the air inlet of the air duct connector.

[0010] Preferably, the support base is provided with a plurality of heat dissipation holes for improving heat dissipation performance and reducing weight.

[0011] Preferably, the support base is further provided with a support base fixing hole for connecting to the ground.

[0012] Preferably, a handle is provided on the top of the housing connecting boss.

[0013] Preferably, it also includes a control circuit board;

[0014] A control box is provided on the side of the housing connecting boss. The control circuit board is located inside the control box. A control box internal wiring hole is provided on one side of the control box and communicates with the drive cavity through the control box internal wiring hole.

[0017] The control circuit board is disposed inside the waterproof inner cavity. The external wiring hole and the internal wiring hole of the control box are disposed inside the connecting outer cavity. The inner partition is provided with an inner partition wiring hole. The connecting outer cavity and the waterproof inner cavity are connected through the inner partition wiring hole.

[0018] Preferably, the device also includes a waterproof cover and a waterproof rubber ring. The waterproof cover has a waterproof cover connecting groove, and the waterproof rubber ring is fitted into the waterproof cover connecting groove. The waterproof cover is attached to the top of the control box by means of screws, and the waterproof rubber ring improves the waterproof effect of the control box.

[0019] Preferably, an inner partition limiting groove is provided in the middle of the inner partition through hole, and a waterproof sleeve is provided on the outside of the line. The waterproof sleeve can be locked onto the inner partition through hole through the inner partition limiting groove.

[0020] The beneficial effects of this utility model's outdoor fan are:

[0021] 1. By setting a through hole for the housing boss at the bottom outside the housing connecting boss, and fixing the air duct connector to the fan housing and covering the outside of the through hole for the housing boss, an L-shaped air inlet facing inward is formed. This can improve heat dissipation capacity while preventing external water from entering the fan, thereby improving the durability of the fan.
