Description
technical field [0001] The invention relates to a water purifier, in particular to a leak-proof device for a household direct drinking water purifier or a pipeline water dispenser. Background technique [0002] With the increasing popularity of household water purifiers, the vigorous development of the water purifier industry has been driven. However, the level of various manufacturers, especially component manufacturers, is uneven, which makes the safety hazards of water purifiers widely exist. Accidents due to water leakage and submersion of users' homes have occurred from time to time, which seriously shakes the market's confidence in water purifiers. One of the important reasons restricting the development of the water purifier industry. It is imminent to solve the water leakage problem of water purifier. [0003] The Chinese invention patent application with the application number 03258390 discloses a water leakage protector, which is purely mechanical, including a bo...
