Pre-filter with explosion-proof device and explosion-proof method thereof

Abstract

The invention relates to a pre-filter with an explosion-proof device and an explosion-proof method thereof. The pre-filter comprises a filter main body and is characterized in that the pre-filter comprises an information collecting device, a controller, an explosion-proof body communicated with the filter main body and at least one explosion-proof hole on the filter main body, the controller is connected to the information collecting device, when the information collecting device has a predetermined value, water in the filter main body is discharged through the explosion-proof hole, and when the information collecting device has no a predetermined value, the explosion-proof hole is closed. When the pressure in the filter or a water pipe connected to the filter is too high or the temperature is too low to reach a certain preset value, through the explosion-proof hole, a part of water in the filter and the water pipe is discharged so that the inner pressure and the temperature are balanced again.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a pre-filter with an explosion-proof device and an explosion-proof method thereof. Background technique [0002] In daily life, in order to improve the quality of water, the water will be filtered through the filter before drinking. During the long-term use of the filter element, the dirt in the water will remain on the inner wall of the filter element, and the accumulation of time will make the filter element body It becomes dirt and carries it, and the water discharged through the filter element contains a large number of bacteria and germs. After drinking for a long time, the human body will cause gastrointestinal lesions and seriously affect the health of the body. Some families are aware of the above-mentioned water problems. When the filter element is used for a period of time, it will clean the filter element or directly replace the filter element. Dir...

Problems solved by technology

[0002] In daily life, in order to improve the quality of water, the water will be filtered through the filter before drinking. During the long-term use of the filter element, the dirt in the water will remain on the inner wall of the filter element, and the accumulation of time will make the filter element body It becomes dirt and carries it. The water discharged through the filter element contains a large number of bacteria and germs. After drinking for a long time, the human body will cause gastrointestinal lesions and seriously affect the health of the body.

Some families are aware of the above-mentioned water problems. When the filter element is used for a period of time, it will clean the filter element or directly replace the filter element. It is appropriate to replace the filter element directly, but it adds a lot of money to life.

[0003] In order to solve the above problems, the applicant applied for the patent No. ZL 201610644392.4 and the patent name is: a related patent for a water purification device with automatic cleaning function and its control method, but this technology still has shortcomings, namely: When the water purifier freezes at low temperature, high pressure or low temperature will cause the water in the water pipe (or water purifier) ​​to freeze and expand, causing it to burst, leak water, or when the outlet of the water purifier encounters blockage, the net The high pressure inside the water tank will also cause the water pipe (or water purifier) ​​to burst, which will cause serious damage to water resources and equipment
