Dual-mode double-sided automatic scraping and washing pre-filter and washing method thereof

Abstract

The invention discloses a dual-mode double-sided automatic scraping and washing pre-filter and a washing method thereof, and relates to the technical field of filters. The dual-mode double-sided automatic scraping and washing pre-filter comprises an upper valve body and a lower valve body, wherein a filter core is arranged in the middle of the upper valve body, a filter cup is arranged outside thefilter core, a rotating seat is arranged at the bottom of the inner cavity of the filter cup, a rotating shaft is arranged in the center of the rotating seat, the lower end of the rotating shaft penetrates through a stainless steel bearing and the filter cup and then is fixedly provided with an impeller through a stainless steel nut, a pair of lugs are oppositely arranged on the side surface of the rotating seat, brush rods are arranged on the lugs through brush rod fixing holes, a brush strip is arranged on the brush rod, the lower valve body is arranged at the bottom of the filter cup, andthe lower valve body is provided with a main water outlet and an auxiliary water outlet. According to the dual-mode double-sided automatic scraping and washing pre-filter, cleaning of the filter screen can be completed through impact force of water while a rechargeable battery can be charged, cleaning can also be driven by a motor, the two modes of automatic sewage discharging and manual sewage discharging are achieved at the same time, and the dual-mode double-sided automatic scraping and washing pre-filter is simple in structure, low in cost, convenient to operate, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a dual-mode double-sided automatic scraping and cleaning pre-filter and a cleaning method thereof. Background technique [0002] The pre-filter is a device that is often used in daily life to filter impurities in water. The impurities in the water are isolated through the filter, but with the prolongation of use time, the filter element in the filter will accumulate more and more There are too many impurities and dirt, and finally the water flow rate of the filter element is too small, which affects the normal water use. Therefore, the filter element of the filter often needs to be cleaned or replaced manually on a regular basis. The traditional pre-filter needs to be disassembled for cleaning the filter element, because Removing and washing the filter screen and filter cup is very cumbersome and a safety issue, which requires professionals to solve.

[0002] The pre-filter is a device that is often used in daily life to filter impurities in water. The impurities in the water are isolated through the filter, but with the prolongation of use time, the filter element in the filter will accumulate more and more There are too many impurities and dirt, and finally the water flow rate of the filter element is too small, which affects the normal water use. Therefore, the filter element of the filter often needs to be cleaned or replaced manually on a regular basis. The traditional pre-filter needs to be disassembled for cleaning the filter element, because Removing and washing the filter screen and filter cup is very cumbersome and a safety issue, which requires professionals to solve it. If it is not removed and washed frequently, it is easy to cause bacteria to grow on the surface of the filter screen, which will lead to secondary pollution of water quality and affect the health of the body.
