Embodiment 1

[0033] As shown in the figure, a self-cleaning pre-filter includes an upper cylinder 1 and a lower cylinder 2 that cooperate with each other. A closed chamber 3 is formed between the upper cylinder 1 and the lower cylinder 2. The upper cylinder The upper part of 1 is provided with a water inlet 4 communicating with the chamber 3, and a filter device 7 is provided in the chamber 3, and the chamber 3 is divided into a water purification chamber and a sewage chamber, the water purification chamber is connected to the water purification port 5, and the sewage chamber is connected to The sewage outlet 6 and the filter device 7 are also provided with a cleaning device, which can rotate around the filter device 7 and clean the filter device 7 .

[0034] The water flow enters from the water inlet 4 and enters the chamber 3 between the upper cylinder body 1 and the lower cylinder body 2. The water flow flowing into the chamber 3 is filtered by the filter device 7, and the clean water is...

Embodiment 2

[0045]Especially with the development of smart homes, more and more families start to use smart toilets. A major feature of smart toilets is the body cleaning function. In many buildings at present, most of the toilets are connected to tap water. The urban tap water pipes are aging or the tap water storage tanks on high-rise buildings cannot be cleaned frequently, so that the tap water contains a lot of rust and mud. There are many large particles of organic matter such as sand. These large particles will cause the nozzle of the smart toilet to be blocked. Due to the entry of large particles of organic matter into the water inlet solenoid valve, the solenoid valve will not close firmly and water leakage will occur. The self-cleaning filter in the present invention can also be used in an intelligent toilet to further filter reclaimed water to remove impurities, and the clean water after removal of impurities is used to flush the body, and the water containing impurities is used ...

Abstract

The invention belongs to the field of filtering devices and provides a self-washing pre-filter. The self-washing pre-filter comprises an upper barrel body and a lower barrel body, which are matched with each other, wherein a sealed chamber is formed between the upper barrel body and the lower barrel body; a water inlet, which is communicated with the chamber, is formed in the upper part of the upper barrel body; the chamber is internally provided with a filtering device and the chamber is divided into a pure water cavity and a sewage cavity; the pure water cavity is connected with a pure wateropening and the sewage cavity is connected with a sewage opening; the filtering device is further provided with a cleaning device; and the cleaning device can rotate around the filtering device and is used for cleaning the filtering device. According to the self-washing pre-filter provided by the invention, the filtering device can be cleaned, without the need of an external force; the filteringdevice keeps a clean state all the time; and mesh holes of a filtering screen are not blocked and the filtering screen does not need to be taken out for washing and replacement, so that the service life of the filtering device is greatly prolonged.

Description

technical field [0001] The invention belongs to the field of filter devices, and relates to a filter, in particular to a self-cleaning pre-filter. Background technique [0002] With the improvement of living standards, people's requirements for water quality are also getting higher and higher. Filtering devices currently on the market all have a certain lifespan. After using for a period of time, the filter screen (filter core) in the filtering device will be taken out for cleaning or replacement, which causes inconvenience to people's lives. Therefore, there is a need for a self-cleaning pre-filter, which has a self-cleaning function while achieving the filtering effect, does not need to manually clean the filter screen or replace the filter element frequently, and can prolong the service life of the filter screen (filter element). Contents of the invention [0003] The object of the present invention is to provide a self-cleaning pre-filter aiming at the above-mentioned...
