Novel filter capable of realizing backflushing automatic cleaning through waterway conversion

Abstract

The invention discloses a novel filter capable of realizing backflushing automatic cleaning through waterway conversion, which can be applied to water filtration, or chemical liquid and biochemical reagent filtration. The structure of the novel filter is provided with two water outlet nozzles, and in normal use, water at a water inlet nozzle passes through a filter material in a cylinder body and then flows out through a filter element tube from the first water outlet nozzle to achieve the purpose of filtering; if cleaning is needed, a relative angle between a cylinder head cover and a cylinder head seat can be turned to a specific direction, so that the water at the water inlet nozzle can firstly flow through the filter element tube and the filter material, and flow out from the second water outlet nozzle, and impurities and dirt trapped by the filter material in the normal flow direction of the water can be discharged from a second water outlet along with the water due to the flushing of water in the reverse flow direction so as to achieve the effect of cleaning a filter element. Therefore, the novel filter is ingenious and reasonable in structure, the filter element of the filter can be conveniently cleaned by only turning the relative angle between the cylinder head cover and the cylinder head seat under the condition of not disassembling so as to achieve the function of automatic cleaning, the use is very convenient, and the effect is very ideal.

Description

technical field [0001] The present invention designs a filter. Background technique [0002] Filters are used in many occasions, such as aquariums, fish ponds, fish ponds and other similar water animal and plant breeding places, as well as water collection places such as pools and swimming pools, which are often used in home environments or commercial and office places. Filters can be used to filter water and keep water clean; in addition, filters are also very common in the application of other liquids, such as chemical liquids, or biochemical reagents. [0003] Filters can be used to clean and filter liquids on a regular or irregular basis. For example, in water filtration, filters can filter out impurities to ensure clean water and prevent water from being polluted. After the filter is used for a long time, a lot of impurities will accumulate on the filter screen. If it is not discharged in time, it will affect the filtering effect and normal use. Therefore, it is necess...

AI Technical Summary

Problems solved by technology

The traditional filter needs to be disassembled first when cleaning, and the filter element must be taken out manually. After the filter element is specially cleaned, the filter element is then put into the filter. Obviously, this cumbersome operation is very inefficient and will bring inconvenience to cleaning and maintenance. Inconvenient, and the disassembly and assembly of the filter usually requires more professional personnel to complete, which is not conducive to public use and widespread popularization, so it can be seen that there is a need for further improvement
