Prefilter with self-cleaning function and cleaning device of prefilter

Abstract

The invention relates to the field of water purification equipment and discloses a prefilter with a self-cleaning function and a cleaning device of the prefilter. The prefilter with the self-cleaning function comprises a housing, a filter screen (10) mounted in the housing and further comprises the cleaning device. The cleaning device comprises a motor (2), a rotary shaft (11) and brush hairs (13) fixedly arranged on the rotary shaft (11); the rotary shaft (11) extends into the filter screen (10), the motor (2) drives the rotary shaft (11) to rotate, and the brush hairs (13) rotate along the rotary shaft (11) to clean the inner wall of the filter screen (10). According to the prefilter provided by the invention, the filter screen is internally cleaned by using the cleaning device, so that the problem that the filter screen of the prefilter is hard to clean is thoroughly solved, the cleaning and maintaining costs of the filter are lowered, the surface of the filter screen is not easily blocked, the filter element of a water purifier is protected to the maximum extent, the service life of the filter element of the water purifier is greatly prolonged, and cogent benefits are brought to consumers.

Description

technical field [0001] The invention relates to the field of water purification equipment, in particular to a pre-filter with self-cleaning function. Background technique [0002] In the existing household water purification industry, the most commonly used products in our daily life are reverse osmosis water purifiers and ultrafiltration water purifiers, but water purification products have certain requirements for water sources, such as municipal tap water, The water pressure requirement is 0.1 to 0.4MPa, which is not a problem for cities and developed counties and towns. However, for the vast rural areas of China, the water quality in many places is very poor, and some even have no tap water. It's all underground well water, very turbid, and they are the ones who need water purification products the most. Due to the poor water quality in rural areas, the filter elements of our commonly used water purifiers are quickly blocked after installation and use, and the filter el...

[0002] In the existing household water purification industry, the most commonly used products in our daily life are reverse osmosis water purifiers and ultrafiltration water purifiers, but water purification products have certain requirements for water sources, such as municipal tap water, The water pressure requirement is 0.1 to 0.4MPa, which is not a problem for cities and developed counties and towns. However, for the vast rural areas of China, the water quality in many places is very poor, and some even have no tap water. It's all underground well water, very turbid, they are the ones who need water purification products the most

Due to the poor water quality in rural areas, the filter element of our commonly used water purifiers will be blocked soon after installation and use, and the filter element must be replaced, that is, the service life of the filter element is very short

Even if the water purifier is equipped with a pre-filter, the pre-filter will soon be blocked by impurities such as sediment and needs to be cleaned frequently, and the cleaning of the pre-filter is difficult for most consumers. Complete, so ordinary water purification products are not suitable for practical use in rural areas
