Abstract

The invention discloses a pre-filter, which comprises an outer framework, a bottle body and a filter screen arranged on the inner side of the outer framework, wherein the outer framework is provided with a plurality of scraping strips used for scraping impurities on the inner wall of the bottle body and the filter screen; the pre-filter further comprises a rotary driving assembly connected with the outer framework, wherein the outer framework is driven to rotate through the rotary driving assembly, so that the scraping strip scrapes impurities on the inner wall of the bottle body and the filter screen. According to the pre-filter, the problem that the normal use of the pre-filter is influenced due to the fact that the structures of product parts are easily damaged due to improper manual scraping operation can be avoided, the dirt removal efficiency can be improved, the labor intensity of workers is reduced, and the production cost is reduced.

Description

Technical field[0001]The present invention relates to the technical field of filtration equipment, in particular to a pre-filter.Background technique[0002]At present, the pre-filter is the first coarse filtration equipment for the whole house water. It can filter the sediment, rust, large particulate matter in the tap water, etc., so as to prevent the large amount of precipitated impurities produced in the urban and residential water supply pipe network from affecting the human body. Cause damage, and play a positive role in preventing hidden pipes, faucets, plumbing, water heaters, boilers, central air conditioners, washing machines, dishwashers, coffee machines and other water appliances (water purifiers, pure water machines, water dispensers), etc. Protective effects. However, the impurities on the pre-filter bottle of the scrapable-washable pre-filter often need to be manually scraped to drain the dirt, and manual scraping is inconvenient to operate, and improper operation can e...
