It should be noted that various changes and modifications can be made by one skilled in the art without departing from the spirit of the invention. These all belong to the protection scope of the present invention.
As shown in fig. 1-2, the present invention provides a hair dryer with noise reduction function, which comprises a hair dryer housing 1, an internal air duct 2, a noise reduction sleeve 3, a driving device 4 and an air guide duct 5.
Wherein, the blower shell 1 and the inner air duct 2 are assembled, and an assembly gap is formed in the middle interlayer; the noise reduction sleeve 3 is arranged between the internal air duct 2 and the driving device 4, and the noise reduction sleeve 3 is profiled with the outer contour of the driving device 4 so as to fix the driving device 4; the noise reduction sleeve 3 is in interference fit with the internal air duct 2 and is fixed in a groove of the blower shell 1 through interference fit.
Further, the noise reduction sleeve 3 comprises an assembly horizontal plane 301, an inclined plane 302, a circular arc convex surface 303 and a vertical plane 304, wherein the assembly horizontal plane 301 is in interference fit with the driving device 4; a convex shoulder is formed at the connecting part of the inclined surface 302 and the assembling horizontal surface 301, and is in snap connection with the driving device 4; the arc convex surface 303 connects the inclined surface 302 and the vertical plane 304, and the vertical plane 301 is embedded in the blower housing 1 for fixing. The opening of the inner air duct 2 near one end of the air inlet duct is sealed by the arc convex surface 303 and the vertical plane 304 of the noise reduction sleeve 3.
Continuing further, the air inlet duct is provided with a plurality of round holes; the length of the inner air duct 2 is smaller than the length of the blower housing 1 in the horizontal direction.
The utility model discloses aVariation exampleFor further explanation.
Based on the above embodiment, the utility model provides a cover 3 of making an uproar falls includes silica gel cover, rubber sleeve or sponge cover.
Based on the above embodiment, the driving device 4 in the present invention includes a high-speed motor or a high-speed motor.
The working principle is as follows:
mechanical vibration on the surface of the driving device 4 is isolated through the structure of the noise reduction sleeve 3; meanwhile, the design of a matching groove between the noise reduction sleeve 3 and the blower shell 1 directly blocks the air flow from the air inlet to pass through the assembly gap between the internal air duct 2 and the blower shell 1, so that the vibration between the internal air duct 2 or the blower shell 1 caused by local high-speed air flow is avoided; thereby eliminating resonance and solving the problem of high-frequency noise of the electric hair drier.
Because without the noise damping sleeve 3, the surface of the drive means 4 can be mechanically vibrated during operation. Meanwhile, in the working process of the product, the air flow can pass through the assembly gap between the internal air duct 2 and the blower shell 1 to generate local high-speed air flow, and the local high-speed air flow can cause the internal air duct 2 or the blower shell 1 to generate vibration. The two vibration frequencies are different, causing a problem of resonance. Resulting in the problem of high frequency noise in hair dryers.
The assembly mode is as follows:
the utility model discloses well drive arrangement 4 is fixed in the middle of falling noise cover 3 through the mode of profile modeling closure or viscose, has restricted drive arrangement 4's degree of freedom through falling noise cover 3. Further, drive arrangement 4 and fall the drive assembly that the cover 3 constitutes of making an uproar wholly pack into inside wind channel 2 in the middle of, fall 3 side end faces of the cover of making an uproar and hug closely with 2 side end faces of inside wind channel, wherein, fall and have the interference fit relation in the medial surface between the cover 3 of making an uproar and the inside wind channel 2 to the holistic degree of freedom of drive assembly has been restricted. Furthermore, the air duct 2 and the assembled driving assembly are integrally fixed on the blower housing 1 by screws or fasteners, and the shoulder at the vertical plane 304 of the noise reduction sleeve 3 is in excessive fit with the sunken groove at the inner side of the blower housing 1. The blower shell 1 is of a left-right symmetrical split structure or a front-back split structure from the axis of the handle.
The foregoing description of the specific embodiments of the invention has been presented. It is to be understood that the present invention is not limited to the specific embodiments described above, and that various changes or modifications may be made by those skilled in the art within the scope of the appended claims without departing from the spirit of the invention.
