Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a centrifugal fan blade structure.
[ background of the invention ]
At present, the food processor in the market is defined to integrate the functions of soybean milk making, dry powder grinding, fruit juice squeezing, meat stuffing making, ice shaving and the like, and bring more convenience to our life.
The existing food processor generally adopts an alternating current motor as a driving source so as to obtain higher working rotating speed and torque transmission ratio, and an output shaft of the alternating current motor is provided with a coaxial fan so as to carry out forced air cooling heat dissipation on the alternating current motor; and the fan generates a large wind noise at a relatively high rotational speed, which is a nuisance to the user, also reducing the service life of the machine,
therefore, the utility model discloses it is just based on above not enough and produce.
[ Utility model ] content
The to-be-solved technical problem of the utility model is to provide a centrifugal fan blade structure, the shape that changes the blade makes the air current flow direction more reasonable, and then has reached the effect that reduces wind and make an uproar.
In order to solve the technical problem, the utility model adopts the following technical scheme: the centrifugal fan blade structure is characterized by comprising a wheel disc arranged in an air channel, wherein a base body is arranged at the center of the wheel disc in a protruding mode, a shaft hole capable of being connected with an output shaft of a motor is formed in the base body, blades are arranged between the base body and the wheel disc and are of a triangular structure, and the blades are perpendicularly arranged on the wheel disc.
The centrifugal fan blade structure is characterized in that the base body is of a cylindrical structure.
The centrifugal fan blade structure is characterized in that one side of the blade extends to the upper end of the outer side wall of the seat body, and the other side of the blade extends to the edge of the wheel disc.
The centrifugal fan blade structure is characterized in that the cross section of the blade is of a right-angled triangle structure.
Compared with the prior art, the utility model discloses a centrifugal fan blade structure has reached following effect:
the center of the wheel disc of the utility model is convexly provided with a seat body, a shaft hole which can be connected with the output shaft of the motor is arranged in the seat body, blades are arranged between the seat body and the wheel disc, the blades are of a triangular structure, and the blades are vertically arranged on the wheel disc; the utility model discloses improve conventional right angle cutting air and be oblique angle cutting air, reduced the area of contact of blade with the air, reached the noise abatement, reduce the effect of wind making an uproar, install the noise that can reduce the cooking machine behind the cooking machine, reinforcing user's experience is felt.
[ description of the drawings ]
The following detailed description of embodiments of the present invention is provided with reference to the accompanying drawings, in which:
fig. 1 is a perspective view of the present invention;
fig. 2 is a side view of the present invention;
fig. 3 is a using state diagram of the utility model installed in the air duct.
[ detailed description ] embodiments
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 3, in this embodiment, the air conditioner includes a wheel disc 1 disposed in an air duct 10, a seat 11 is protruded from a center position of the wheel disc 1, a shaft hole 111 capable of being connected to an output shaft of a motor is formed in the seat 11, a blade 2 is disposed between the seat 11 and the wheel disc 1, the blade 2 is of a triangular structure, and the blade 2 is vertically disposed on the wheel disc 1. The center of the wheel disc of the utility model is convexly provided with a seat body, a shaft hole which can be connected with the output shaft of the motor is arranged in the seat body, blades are arranged between the seat body and the wheel disc, the blades are of a triangular structure, and the blades are vertically arranged on the wheel disc; the utility model discloses improve conventional right angle cutting air and be oblique angle cutting air, reduced the area of contact of blade with the air, reached the noise abatement, reduce the effect of wind making an uproar, install the noise that can reduce the cooking machine behind the cooking machine, reinforcing user's experience is felt.
The principle of the centrifugal fan blade is axial air inlet and radial air outlet, and the centrifugal force is utilized to do work, so that the pressure of the air is improved.
As shown in fig. 1 to 3, in the present embodiment, the seat 11 has a cylindrical structure, so as to reduce the resistance.
As shown in fig. 1 to 3, in the present embodiment, one side of the blade 2 extends to the upper end of the outer sidewall of the seat body, and the other side of the blade 2 extends to the edge of the wheel disc 1, so as to achieve the effect of cutting air by a slope and reduce noise.
As shown in fig. 1 to 3, in the present embodiment, the cross section of the blade 2 is a right triangle structure. The air is cut by the inclined plane, so that the contact area of the blade and the air is reduced, and the wind noise is reduced; specifically, the shape of the triangle may be isosceles direct triangle.
The above is only the preferred embodiment of the present invention, which is not used to limit the present invention, as long as the technical solution of the purpose of the present invention is realized by the same means, all belong to the protection scope of the present invention.
