Abstract
The utility model provides a draught fan which at least comprises a base, a motor, a coupler, a casing and blades, wherein one end of the coupler is connected with the motor through a belt or a chain, the coupler and the motor are positioned on the same plane, the casing is provided with a ventilation port and is in a volute shape integrally, the blades are arranged in the casing and fixedly connected with the other end of the coupler extending into the casing, the coupler, the casing and the blades are arranged in a straight line, and the edge of the casing is the arched edge surface. By means of the technical scheme, air pressure of the draught fan can be strengthened effectively.
Description
Technical field
The utility model relates to blower fan field, more specifically, relates to a kind of centrifugal fan.
Background technique
Blower fan is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure, and it is a kind of driven fluid machinery.
Existing blower fan is all mostly to adopt to imitate the passage that the casing of scroll casing shape is used as supplying gas in the design of dispatch gas, then draws by air port.Wherein, the Specifeca tion speeification of blower fan has air quantity, blast, air horsepower etc., and therefore, the blast of blower fan is an important parameter weighing fan performance, so how to provide the blast of blower fan also just to have become a major issue in the art.
Model utility content
In view of the above, the purpose of this utility model is to provide a kind of blower fan, and how the problem of the blast of blower fan is provided for solving prior art.
For achieving the above object and other relevant objects, the utility model provides following technological scheme:
A kind of blower fan is provided, at least comprises a pedestal, a motor, a coupling, casing and an impeller, one end of described coupling is connected in described motor by belt or chain, and with described motor in same plane; Described casing has a port and integral body is scroll casing shape; Described impeller is placed in the inside of described casing and is fixedly connected with the other end that stretches into the coupling of described casing inside, and the installation that is arranged in a straight line of described coupling, casing and impeller; Wherein, the edge of described casing is dome-shaped edge surface.
Preferably, described pedestal below is also laid with a plurality of shock absorbing seats that are connected in described pedestal.Due to, described blower fan build and structure are larger and heavy, and in the running blower fan self with strong vibrations, therefore add the stability that blower fan integral body can be provided after shock absorbing seat.
As mentioned above, the utlity model has following beneficial effect: by the edge of casing is made into dome-shaped edge surface, making derives along described dome-shaped edge surface at the air-flow of casing inside, with respect to the casing of existing square or other non-dome-shaped edge surfaces, the utility model can effectively strengthen the blast of blower fan.
Accompanying drawing explanation
In order to be illustrated more clearly in the scheme in the utility model embodiment, to be briefly described describing the accompanying drawing of required use in specific embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those skilled in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation of a kind of blower fan that Fig. 1 provides in one embodiment for the utility model.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Based on embodiment of the present utility model, all other embodiments that those of ordinary skills obtain under the prerequisite of not making creative work, belong to the scope that the utility model is protected.
As Fig. 1, show the structural representation of a kind of blower fan that the utility model provides in one embodiment, from figure, a kind of blower fan is provided, specifically comprise a pedestal 1, a motor 2, a coupling 3, casing 5 and an impeller 6, one end of described coupling 3 is connected in described motor 2 by belt 4 or chain, and with described motor 2 in same plane; Described casing 5 has a port 53 and integral body is scroll casing shape; Described impeller 6 is placed in the inside of described casing 5 and is fixedly connected with the other end that stretches into the coupling 3 of described casing 5 inside, and the installation that is arranged in a straight line of described coupling 3, casing 5 and impeller 6; Wherein, the edge of described casing 5 is dome-shaped edge surface 51.
Particularly, below described pedestal 1, be also laid with a plurality of shock absorbing seats 7 that are connected in described pedestal 1.Due to, described blower fan build and structure are larger and heavy, and in the running blower fan self with strong vibrations, therefore add the stability that blower fan integral body can be provided after shock absorbing seat 7.
In sum, the utility model is by being made into dome-shaped edge surface 51 by the edge of casing 5, making derives through port 53 along described dome-shaped edge surface 51 at the air-flow of casing 5 inside, with respect to the casing 5 of existing square or other non-dome-shaped edge surfaces 51, the utility model can effectively strengthen the blast of blower fan.So the utility model has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
