Embodiment Construction

[0033] In order to make the above objectives, features and advantages of the present invention more obvious and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following description, many specific details are explained in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementation disclosed below.

[0034] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element...

Abstract

The invention relates to a dust collector, a motor assembly and a shell structure thereof. The motor assembly comprises a motor and the shell structure, wherein the shell structure comprises a machineshell and an exhaust assembly; the motor is arranged in an accommodating cavity of the machine shell; and air is sucked from a machine shell air suction port and is discharged into an exhaust channelof the exhaust assembly through an exhaust port. Due to the fact that a plurality of silencing cavities which are arranged at intervals are formed in the inner wall of the exhaust channel, noise in the exhaust process is absorbed by the silencing cavities arranged at intervals, and then exhaust noise is reduced. By arranging the silencing cavities, prolonging of the length of the exhaust channelcan be avoided, the size of the shell structure is further reduced, the size of the motor assembly is further reduced, the size of the dust collector is reduced, and the structure of the dust collector is more compact. Meanwhile, due to the fact that prolonging of the length of the exhaust channel is avoided, increasing of the exhaust air resistance can be avoided, and the exhaust performance of the dust collector can be effectively guaranteed.

Description

Technical field [0001] The present invention relates to the technical field of noise reduction structures, in particular to a vacuum cleaner, a motor assembly and a shell structure thereof. Background technique [0002] The traditional vacuum cleaner uses a motor to drive the blades to rotate at a high speed, generating negative air pressure in a sealed housing to form a suction source, and then sucking dust. However, as the power and speed of the motor become higher and higher, the noise generated by the motor becomes higher and higher, which in turn affects the user experience. Summary of the invention [0003] Based on this, it is necessary to address the above problems and provide a vacuum cleaner, a motor assembly and a housing structure that can effectively reduce noise. [0004] A shell structure of a motor assembly, including: [0005] A housing is formed with an accommodation cavity for installing a motor, the housing has an air suction port and an air outlet, and the air d...
