Abstract

The invention provides a pneumatic component comprising an axial diffuser, a dust collector and a compressor, the pneumatic component comprises a wheel cover, an impeller and the axial diffuser, the impeller is located in the wheel cover, an airflow channel is formed between the impeller and the wheel cover, the axial diffuser is connected to one axial end of the impeller, and the axial diffuser is connected to the other axial end of the impeller. And the impeller is arranged in the axial diffuser and can enable airflow coming out of the airflow channel to enter the axial diffuser to be pressurized, the width of the airflow outlet end of the impeller is smaller than that of the airflow inlet end of the axial diffuser, a certain gap is formed between the airflow outlet end of the impeller and the airflow inlet section of the axial diffuser, and a vaneless diffusion section is formed. The structure of the diffuser can axially extend under the condition that the effective diffusion capacity is not reduced, the radial structure size of the motor is effectively reduced, and noise is reduced.

Description

technical field [0001] The invention relates to the technical field of diffuser, in particular to a pneumatic component including an axial diffuser, a vacuum cleaner and a compressor. Background technique [0002] Small compressors are more and more widely used in the home appliance industry, and their structure tends to be micro-miniature. Generally, home appliance compressors have the characteristics of small pressure ratio and small volume. Usually, the compressor structure is a centrifugal impeller + radial diffuser, in which the radial The characteristic of the diffuser is that the diffusing effect is obvious, but its large outer diameter is the limiting factor for its application in vacuum cleaners and other products, and the outlet end of the impeller is close to the leading edge of the diffuser blade, which affects the acoustic performance of the compressor. [0003] Since the diffuser in the prior art has technical problems such as large radial size and poor acousti...
