Problems solved by technology

[0004] In this volute, the inner wall of the part of the annular cavity between the first air passage and the second air passage is provided with an isolation step for blocking the air flow passing through. The step is not in the air passage and has little influence on the incoming flow. To prevent leakage, let alone deal with incoming water mist

Abstract

The invention discloses an air inlet device which comprises an air inlet part. The air inlet device is characterized in that the air inlet part comprises a first bottom plate, a second bottom plate and side plate assemblies arranged on the peripheries of the first bottom plate and the second bottom plate, the first bottom plate and the second bottom plate are adjacently arranged, an open air duct is defined by the side plate assemblies and the bottom plates, an inlet of the air duct is formed at an opening, and the inlet is positioned at one end, far away from each bottom plate, of each side plate; and the first bottom plate and the second bottom plate are each provided with a first end and a second end which are opposite, the first ends of the first bottom plate and the second bottom plate are close to each other, the second ends of the first bottom plate and the second bottom plate are far away from each other, the first end of the second bottom plate is farther away from the inlet of the air duct relative to the first end of the first bottom plate, and therefore a step structure is formed between the first end of the second bottom plate and the first end of the first bottom plate. The invention further discloses a fan system with the air inlet device and a cleaning machine with the fan system.

Description

technical field [0001] The invention relates to an air inlet device, a fan system using the air inlet device, and a cleaning machine using the fan system. Background technique [0002] The air duct is a key design link in the fan system. Unreasonable air duct design may even cause problems such as dust, scale, and mold inside the air duct, especially when there is a lot of water and dust inhaled. For serious cases, the circuit failure will be caused by failure to clean up in time, and the unreasonable design of the air duct will cause the user to bear a lot of unnecessary use and maintenance costs, and lead to low fan efficiency, high noise, and high energy consumption. [0003] For example, the volute of a vortex fan disclosed in the Chinese patent application number 201620032459.4 has an annular cavity between the inner wall of the shell cavity and a plurality of blades on the impeller, and is respectively provided at different circumferential positions of the annular cavi...
