Abstract
A stepless speed changing fan relates to an electric fan, in particular to an improved structure of an existing fan. The stepless speed changing fan comprises a base, a bed, a fan oscillating mechanism, an oscillating bed and a fan blade assembly. The bed is installed on the base, the fan oscillating mechanism is installed inside the bed, and the oscillating bed is arranged above the bed. The oscillating bed is connected with the fan oscillating mechanism, and the fan blade assembly is arranged at the front of the oscillating bed. The stepless speed changing fan further comprises a stepless speed changing motor, a coupler and a bearing block. A motor installation frame is arranged inside the oscillating bed, and the stepless speed changing motor is fixed on the motor installation frame. The bearing block is installed inside the oscillating bed, and a blade shaft of the fan blade assembly is installed on the bearing block. The blade shaft is connected with a rotating shaft of the stepless speed changing motor through the coupler. The stepless speed changing fan resolves problems that wind speed gears of the existing fan are limited and needs of users cannot be met.
Description
Technical field
The utility model relates to electric fan, is specifically related to the improvement to existing fan structure.
Background technique
Present fan blade rotating speed has 2-4 speed governing shelves, and people can select different wind as required.This fan can not satisfy needs of people because the wind speed shelves are limited, therefore is necessary to invent a kind of fan with stepless shift function.
The model utility content
The purpose of the utility model provides a kind of stepless change fan, and it is limited that the utility model has solved existing fan wind speed shelves, can not satisfy the problem of needs of people.
The stepless change fan of the utility model; Comprise base 1, foundation mass 2, oscillating fan mechanism 3, yaw support 4 and Blower Plate Assembly 8; Foundation mass 2 is installed in above the base 1, and oscillating fan mechanism 3 is installed in the foundation mass 2, and yaw support 4 is arranged at foundation mass 2 tops; Yaw support 4 linked, fan oscillating head mechanisms 3, Blower Plate Assembly 8 is installed on yaw support 4 front sides; Also comprise stepless variable-speed motor 5, coupling 6, bearing support 7; Be provided with motor scaffold 4-1 in the yaw support 4, stepless variable-speed motor 5 is fixed on the motor scaffold 4-1; Bearing support 7 is installed on yaw support 4 inside, and the sharf 8-1 of Blower Plate Assembly 8 is installed on the bearing support 7; Sharf 8-1 connects the rotating shaft of stepless variable-speed motor 5 through coupling 6.
The stepless change fan of the utility model can be realized the stepless speed regulation of fan blade, has the advantage that operates steadily.
Description of drawings
Fig. 1 is the utility model structural representation.
Symbol description among the figure: base 1, foundation mass 2, oscillating fan mechanism 3, yaw support 4, motor scaffold 4-1, stepless variable-speed motor 5, coupling 6, bearing support 7, Blower Plate Assembly 8, sharf 8-1.
Embodiment
Below in conjunction with accompanying drawing and with illustrated embodiments the utility model is done detailed explanation.
Consult Fig. 1, stepless change fan, stepless change fan; Comprise base 1, foundation mass 2, oscillating fan mechanism 3, yaw support 4 and Blower Plate Assembly 8; Foundation mass 2 is installed in above the base 1, and oscillating fan mechanism 3 is installed in the foundation mass 2, and yaw support 4 is arranged at foundation mass 2 tops; Yaw support 4 linked, fan oscillating head mechanisms 3, Blower Plate Assembly 8 is installed on yaw support 4 front sides; Also comprise stepless variable-speed motor 5, coupling 6, bearing support 7; Be provided with motor scaffold 4-1 in the yaw support 4, stepless variable-speed motor 5 is fixed on the motor scaffold 4-1; Bearing support 7 is installed on yaw support 4 inside, and the sharf 8-1 of Blower Plate Assembly 8 is installed on the bearing support 7; Sharf 8-1 connects the rotating shaft of stepless variable-speed motor 5 through coupling 6.
The said fans oscillating head mechanism adopts existing technology oscillating fan mechanism commonly used, the product that stepless variable-speed motor can adopt Shanghai City cycloid speed reducer Co., Ltd to produce.
Above embodiment is more preferably embodiment a kind of of the utility model, and common variation that those skilled in the art carry out in present technique scheme scope and replacement should be included in the protection domain of the utility model.
