Abstract

The utility model discloses a mute impeller of a hair drier. The mute impeller comprises a baseboard, and blades annularly distributed at the edge of the surface of the baseboard, wherein the middle part of the baseboard is provided with a central shaft, the central shaft is provided with a central hole in which a motor spindle can be sleeved, one side of each blade extends to be connected with the central shaft, the structural strength of all the blades can be improved, the turbulence intensity is reduced, the gas flow stability is improved, and the vibration due to the shaking of the blades when the impeller is rotated is prevented, so that the service life of a motor is improved, and the noise is reduced.

Description

A kind of quiet impeller of blower

Technical field

The utility model relates to the quiet impeller that blower is used.

Background technique

As shown in Figure 1, the impeller of existing blower generally comprises the base plate 1 of a circle; Be located at the middle part of base plate 1, can be inserted in the center hole 11 of motor shaft; And annular spread is at the blade 2 of base plate 1 marginal surface.The blade 2 of this impeller is separated from one another, all only depend on the junction surface of itself and base plate to support, and be plastic material, its structural strength is lower, during the impeller high speed rotating, can form larger turbulent flow at the middle part of base plate, under the effect of centrifugal force and turbulent gas, rocking can appear in blade 2, cause bladed disk vibration, affect the working life of motor and produce larger noise, and the extent of vibration of impeller can be aggravated with the growth of the quantity of blade 2, so, the blade quantity of impeller generally should not surpass 10, and blade quantity is less, and the air quantity of its corresponding generation is also less.

Summary of the invention

The purpose of this utility model is to provide a kind of structural strength better, rotates the more stably quiet impeller of blower.

The quiet impeller of blower described in the utility model, comprise base plate, and annular spread is at the blade at backplate surface edge, the middle part of described base plate is provided with central shaft, central shaft has the center hole that can be inserted in motor shaft, and a vaned side extends to central shaft and is connected.

The utility model is owing to arranging central shaft at the middle part of base plate, by central shaft all blades are linked together, can improve vaned structural strength, and reduction turbulence intensity, improve the stationarity of gas flow, vibrate because of rocking of blade when preventing vane rotary, thus the working life of improving motor, and reduce noise.

Embodiment

Extremely shown in Figure 4 such as Fig. 2, the quiet impeller of described blower, comprise base plate 1, and annular spread is at the blade 2 of base plate 1 marginal surface, the middle part of described base plate 1 is provided with central shaft 3, central shaft 3 has the center hole 31 that can be inserted in the motor shaft (not shown), one side of all blades 2 extends to central shaft 3 and is connected, to improve the structural strength of all blades 2, and the reduction turbulence intensity, the stationarity of raising gas flow is vibrated because of rocking of blade 2 when preventing vane rotary, thereby improve the working life of motor, and reduce noise.

As shown in Figure 2, the quantity of described blade can arrange as required, as can being set to be lower than 10 by existing quantity, but for improving the air quantity of blower, can arrange more than 10, is illustrated in figure 2 as 18 situation.

As shown in Figure 2, be further to improve the structural strength of the blade 2 of impeller, can be provided with in the outside of all blades 2 one with all blade 2 common reinforcement outer rings 4 that are connected.

As shown in Figure 3, described base plate 1 is the spherical crown shape, can further improve the stationarity of gas flow, certainly, and also can be for adopting existing structure.

As shown in Figure 2, the structure that is formed in one of described impeller.
