Abstract

The invention belongs to the technical field of buildings, and discloses a fan mechanism, a filter element device and cleaning equipment. The fan mechanism comprises a fan support, a centrifugal fan and an air inlet cover assembly; the centrifugal fan is located in the fan support, and the axial upper portion of the centrifugal fan is installed on the fan support; the air inlet cover assembly comprises an air inlet cover and an air guide cylinder; the fan support is installed above the air inlet cover; a first air inlet hole is formed in the air inlet cover; the air guide cylinder communicateswith the first air inlet hole and stretches into the lower portion of the air inlet cover; the axial lower portion of the centrifugal fan stretches into the air guide cylinder; and an axial gap communicating with the outside is formed between the air guide cylinder and the peripheral wall of the centrifugal fan. The axial gap is formed between the centrifugal fan and the air guide cylinder, so that an emergency air duct can be formed between the centrifugal fan and the air guide cylinder; and when the filter element mechanism is blocked, the first air inlet hole can communicate with externalair through the emergency air duct to prevent the case that the centrifugal fan is burnt out due to too higher negative pressure at the position of the first air inlet hole so as to achieve the overload protection effect.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a fan mechanism, a filter element device and cleaning equipment. Background technique [0002] At present, the existing cleaning robots on the market filter dust and other fine particles during the cleaning process mainly through the filter element + fan, specifically by forming a negative pressure in a closed box to achieve the effect of dust adsorption and filtration. At present, the existing cleaning robot mainly consists of side brush system, main brush system, dust vibration system and dustbin. The dust vibration system is the main difficulty, mainly because of the cooperation between the fan and the filter element and the life of the dust vibration system. How to effectively and safely extract the air from the filter element to form a negative pressure is also a common problem, and abnormalities often occur. Existing cleaning robots are relatively easy to improve thei...
