The fan is characterized by also comprising a fixing plate and a circular wall, wherein the fixing plate is fixedly arranged on the electric motor, the circular wall is connected with the fixing plate, vent holes are arranged on the fixing plate, the fixing plate is connected with the rear end of the circular wall, the circular wall covers the outside of rotating fan blades, a wind guide fan blade group is arranged at the front end of the circular wall, and a rotating plane of rotating fan blades is tilted with a blade plane of the wind guide fan blade group. According to the fan, the circular wall which covers the outside of rotating fan blades is provided, the wind guide fan blade group is arranged at the front end of the circular wall, and the rotating plane of rotating fan blades is tilted with the blade plane of the wind guide fan blade group, so that wind can be diverted to side faces of the circular wall, the wind-blowing range of the fan is increased, and the economic benefits are greatly increased.

Description

A kind of spreading type fan

Technical field

The utility model relates to the fan product scope, is specifically related to a kind of spreading type fan

Background technique

Fan is household electric appliance commonly used in people's daily life; Existing fan structure is as shown in Figure 1; Form by fan main body 11 and flabellum 12; And when this flabellum 12 rotated, its scope of effectively drying only was confined to and the relative position of flabellum 12 slewing areas, and the blowing effective coverage is very limited; Increase the blowing scope if desired then needs fan is set more, and its economic benefit is not high

Summary of the invention

for overcoming above-mentioned defective, the purpose of the utility model promptly is a kind of spreading type fan.

The purpose of the utility model realizes through following technological scheme:

A kind of spreading type fan of the utility model, mainly comprise: the rotation flabellum that motor is connected with the motor power output shaft also comprises: be fixedly installed on fixed plate and the ring wall that is connected with fixed plate on the motor; Said fixed plate is provided with vent hole, and said fixed plate is connected with the rear end of ring wall, and said ring wall covers outside the rotation flabellum, and the front end of said ring wall is provided with wind-guiding flabellum group, and the leaf plane of the plane of rotation of said rotation flabellum and wind-guiding flabellum group tilts.

are further, and said wind-guiding flabellum group is made up of more than one wind-guiding flabellum.

are further, and the rear end of said wind-guiding flabellum group is lower than the plane of rotation of rotation flabellum.

are further, and the front end of said ring wall is coated with the frustoconic shape protective cover, and the little round table surface of said frustoconic shape protective cover is provided with air-guiding hole.

are further, are provided with enhancing device at said motor front end and at the rear of rotation flabellum.

Improve as another kind of , and said enhancing device is a device for atomizing liquid.

Improve as another kind of , and said enhancing device is a heating equipment.

Improve as another kind of , and said enhancing device is the ultrasonic wave damping device.

Improve as another kind of , and said enhancing device is the ozone sterilization device.

Has in the utility model and cover the outer ring wall of rotation flabellum, and the front end of ring wall is provided with wind-guiding flabellum group, and since the plane of rotation of rotation flabellum and the leaf plane of wind-guiding flabellum group tilt; Therefore, can the side of wind water conservancy diversion to ring wall have been increased the blowing scope of fan, increase economic benefit greatly.

Description of drawings

In order to be easy to explanation, the utility model is done to describe in detail by following preferred embodiment and accompanying drawing .

Fig. 1 is existing fan overall structure schematic representation;

Fig. 2 is the cross-sectional view at a visual angle of the utility model;

Fig. 3 is the cross-sectional view at another visual angle of the utility model.

Embodiment

For the purpose, technological scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

See also Fig. 2 and Fig. 3, a kind of spreading type fan of the utility model mainly comprises:

motor 21 and the rotation flabellum 22 that motor 21 ptos are connected also comprise: be fixedly installed on fixed plate 23 and the ring wall 24 that is connected with fixed plate 23 on the motor 21; Said fixed plate 23 is provided with vent hole; Said fixed plate 23 is connected with the rear end of ring wall 24; Said ring wall 24 covers outside the rotation flabellum 22, and the front end of said ring wall 24 is provided with wind-guiding flabellum group 25, and the leaf plane of the plane of rotation of said rotation flabellum 22 and wind-guiding flabellum group 25 tilts.

are further, and said wind-guiding flabellum group 25 is made up of more than one wind-guiding flabellum.

are further, and 25 rear ends of said wind-guiding flabellum group are lower than the plane of rotation of rotation flabellum 22.

are further, and the front end of said ring wall 23 is coated with frustoconic shape protective cover 26, and the little round table surface of said frustoconic shape protective cover 26 is provided with air-guiding hole.Said frustoconic shape protective cover 26 had both strengthened the wind-guiding performance, had prevented that also 22 couples of people of rotation flabellum from causing injury.
