Problems solved by technology

[0003] When the user opens the water purifier dispenser (such as a faucet) to take water, the pressure in the water storage unit drops instantly and the high pressure switch that was originally disconnected is instantly closed. After the user finishes taking the water and closes the water purifier dispenser, the pressure in the water storage unit increases The rise makes the high-voltage switch disconnected, which leads to frequent start-up of the water purification device and poor stability
This frequent start-up leads to a high failure rate of the water inlet valve and other components, which seriously affects the service life of the water purification device

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water purification device and a control method with the water purification device. Background technique [0002] The existing water purification device is equipped with a high-pressure switch for detecting the pressure of the water storage unit. When the pressure in the water storage unit is low, the high-pressure switch is closed to open the water inlet valve, and the water purification device starts water production; The switch is disconnected to close the water inlet valve, and the water purification device is shut down. [0003] When the user opens the water purifier dispenser (such as a faucet) to take water, the pressure in the water storage unit drops instantly and the high pressure switch that was originally disconnected is instantly closed. After the user finishes taking the water and closes the water purifier dispenser, the pressure in the water storage unit i...
