Description

Blower fan

Technical field

The utility model relates to a kind of blower fan.

Background technique

The blower fan leg of existing blower fan is located at crust of weathering place, and its centre-of gravity shift is easy to overturning, uses dangerously, and profile is not attractive in appearance yet.

The model utility content

The purpose of this utility model provides a kind of barycentre steadiness, good stability, the blower fan of safe in utilization and beautiful shape.

In order to achieve the above object, the utility model be achieved in that it comprise the crust of weathering, motor, motor bearing, by the fan blade and the blower fan leg in the crust of weathering of being located at of driven by motor; It is characterized in that: also be provided with motor housing outside the motor bearing, the blower fan leg is located at the below of motor housing, and their integral molded plastics that is connected as a single entity form.

The utility model further is improved to, and the blower fan leg is " eight " font, and the bi-side of its two support arm and motor housing are connected as a single entity, and the inside horizontal stretching in both sides, its underpart connects, and the bottom of the crust of weathering is stretched in the front of both sides, its underpart.Motor housing is fixedlyed connected by fastening piece with the motor bearing.The motor bearing is fixedlyed connected by fastening piece with the crust of weathering.Be provided with the radiation hole that Open Side Down at the rear portion of motor housing.On motor housing, also be provided with handle.

The utility model compared with prior art has following advantage:

1, barycentre steadiness, good stability can overturning during use, and is safe and reliable;

2, beautiful shape;

3, easy to assembly, cost of production is low.

Embodiment

Below in conjunction with drawings and Examples the utility model is done further detailed description:

As shown in Figure 1, 2, it comprises the crust of weathering 1, motor 5, motor bearing 6, is fanned 7, is located at the outer motor housing 8 of motor bearing, is located at handle 10 and blower fan leg 4 on the motor housing by the fan blade 3, the motor radiating that are located in the crust of weathering of driven by motor.On the crust of weathering 1, be provided with intake grill 12 and exhaust outlet 11.Be positioned at motor radiating at the rear portion of motor housing 8 and fan 7 places and be provided with the radiation hole 81 that Open Side Down, can arrive in waterproof effect.Blower fan leg 4 is positioned at the below of motor housing 8, and it is " eight " font, and its two support arm 42 is connected as a single entity with the bi-side of motor housing 8, the integral molded plastic moulding, both sides, its underpart 43 inside horizontal stretchings connect, and its underpart two side bottoms 41 stretch to the bottom of the crust of weathering 1, its two arms support motor shell 8.Motor housing 8 is fixedlyed connected by fastening piece 9 with motor bearing 6, and this fastening piece is a bolt.Motor bearing 6 is fixedlyed connected by fastening piece 2 with the crust of weathering 1, and this fastening piece is a bolt.

During installation,, reduced installation procedure one, reduced cost of production, improved the production work efficiency because motor housing 8 and blower fan leg 4 integral molded plastics form.Because blower fan leg 4 is arranged on the below of motor housing 8, and the part of blower fan leg also is positioned at the below of the crust of weathering 1, makes the gravity balance of whole blower fan, so not prone to tip over.
