Problems solved by technology

[0007] During the working process of the vacuum cleaner, in order to reduce the vibration of the motor itself and the noise emitted by the fan blades, most vacuum cleaners use motor covers, and various forms of sound-absorbing materials are installed in the motor covers, but the effect is not ideal.

Embodiment Construction

[0027] The motor cover structure of the present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments:

[0028] Such as Figure 1-5 As shown, the motor cover of the present invention includes a motor front cover 12 , an air filter cover 13 and a cyclone shaper 11 . The motor 10 includes two coaxially arranged cylindrical structures, and a boss 103 is formed at the top center of the large-diameter cylindrical end 101 of the working impeller inside, and a suction hole 104 is formed in the middle of the boss 103. The large-diameter cylinder 101 Limiting ribs or protrusions (not shown in the figure) are arranged below the exhaust hole 105 of the exhaust hole. The small-diameter cylindrical end 102 is provided with a rotor stator and control elements and the like.

[0029] The motor front cover 12 is a cylindrical structure with one end closed, and a circular through hole is formed in the middle of the closed end of t...

Abstract

The invention discloses a motor cover for accommodating a motor, which comprises a motor front cover and an air filter hood; wherein the air filter hood comprises a cylindrical meshed exhaust part on which a ventilation hole is formed; an end part of the exhaust part is provided with a fixed baffle and an exhaust hole, and the outside of the end part is fixedly connected with an annular resonant chamber; a cyclone former is arranged between the motor and the motor front cover. The inhaled air stream forms cyclone by arranging the cyclone former between the motor and the motor front cover; wind power is consumed in the cyclone manner and a trace quantity of dust in the wind power is led to the inner side of the resonant chamber, such that the reduction of wind power results in reduction of volume of noise; meanwhile, through holes with different diameters are formed on the inner side surface of the resonant chamber to broaden the effective silence frequency band of the resonant chamber; furthermore, a frequency-lowering groove is arranged in the inner side of the ventilation hole of the meshed exhaust part, so that the divergence of air stream is improved, the air outlet frequency is altered and the voice quality of the vacuum cleaner is greatly improved.

Description

technical field [0001] The invention relates to a vacuum cleaner; in particular, it relates to a motor cover of the vacuum cleaner. Background technique [0002] Generally, a vacuum cleaner is a device that uses a vacuum to generate suction to inhale air, make the air flow through various filters, filter foreign objects in the air, and clean the room. [0003] Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body. The suction pipeline includes a suction head and a suction pipe. The suction head has a downward opening. The suction port communicates with the air inlet of the fan inside the body through the telescopic pipe and the flexible pipe of the suction pipe. When the vacuum cleaner is running, the motor drives the impeller of the fan to rotate at a high speed, exhausting the air in the vacuum cleaner, forming an instantaneous vacuum in the vacuum cleaner...
