Abstract

The invention relates to a service life monitoring device for a filter element of a water purifier. The device comprises a first filter element, a water inlet electromagnetic valve, a flowmeter, a second filter element, a third filter element and a gooseneck faucet successively connected through a pipeline; a mechanical switch and a three-in-one integrated module are mounted between the purified water outlet of the third filter element and the gooseneck faucet; the three-in-one integrated module is composed of a control panel, and a flow monitoring device and a display screen separately connected to the control panel; the mechanical switch and the water inlet electromagnetic valve are separately connected to the control panel; and the flowmeter is connected to the flow monitoring device. According to the device, a client can master the service life conditions of the filter elements immediately, so that the filter elements are replaced immediately and conveniently, and the drinking water safety is ensured.

Description

technical field [0001] The invention relates to a life monitoring device for a filter element of a water purifier, belonging to the technical field of water purification treatment equipment. Background technique [0002] At present, various types of household water purifiers on the market are generally equipped with several stages of filter elements to purify and remove suspended solids, colloids, and microorganisms in the water. The filter elements at all levels have their own service life. If the filter element is replaced irregularly, it is easy to cause secondary pollution. Not only can it not purify the water body, but it will increase the content of harmful substances in the water. In order to ensure the safety of the final purified water, so that users can drink safe and clean water, users need to replace the filter element whose life has expired on a regular basis. In the prior art, the user often replaces the filter element regularly according to the service life t...

Problems solved by technology

However, in actual use, due to the differences in user habits and daily use frequency, this method has some defects. For customers with less daily use frequency, the daily running time of the water purifier is shorter, and the corresponding filter element is used for a relatively long time. Short, when the filter element is replaced according to the instruction manual, the filter element has not yet reached the real end of life, resulting in premature replacement of the filter element, resulting in waste of resources; and for customers who use more frequently every day, it is likely that the life of the filter element has expired earlier, but Users are still using it, which affects water quality and safety

Therefore, the method of evaluating the life of the filter element based on the use time cannot accurately determine whether the filter element needs to be replaced
