AI Technical Summary

Technical Problem

The existing self-cleaning stations for lawnmowers have insufficient suction capacity of their blower devices, resulting in inadequate extraction of gas containing grass clippings and sludge, which affects the cleaning effect and may lead to the accumulation of dirt.

Method used

Design a self-cleaning station for lawnmowers with a fan device. By setting the fan device in the dust collection box assembly, a closed gas circulation loop is formed. The stability of airflow and suction efficiency are improved by using a static guide vane array and tangential air outlet guide. Sealing and heat dissipation are ensured by sealing rings and cooling components.

Benefits of technology

It achieves efficient gas extraction and transportation, reduces dirt residue, improves the working environment of the cleaning station, and enhances the dirt collection and treatment capacity and the operational reliability of the equipment.

Abstract

This invention discloses a self-cleaning station for lawnmowers with a fan device, comprising: a base station body, a dust collection box assembly, and a circulating water tank assembly; the dust collection box assembly houses the fan device, which is sealed to the circulating water tank via a dust collection pipe and sealed to the dust collection box assembly via a blower pipe, forming a closed-loop gas circulation circuit; the fan device includes: a fan assembly comprising a rotating shaft and moving blades fixed to the rotating shaft; a fan housing having an air inlet and surrounding the moving blades circumferentially; a stationary guide vane array disposed on the fan housing, including multiple air outlet guides arranged circumferentially along the moving blades, the air outlet direction of the air outlet guides being tangential to the fan housing, and this tangential direction being opposite to the rotation direction of the moving blades; and a motor assembly for providing power to the rotating shaft. This invention reduces airflow impact loss and improves suction efficiency by optimizing the matching relationship between the air outlet guide direction and the rotation direction of the moving blades.
