The utility model relates to a water filter, in particular to a water filter capable of measuring and displaying the water flow value of the water filter.

At present, due to industrial development and environmental pollution, water resources are also damaged to varying degrees. The disinfection treatment such as chlorination done by the water company to kill the fungus in the water also makes the water contain chemical substances such as chloride. In order to ensure clean water, many families have purchased water filtration equipment to filter impurities in the water and absorb chemical substances.

The water filtering function of the water filter is completed by the activated carbon filter element installed inside. The activated carbon filter element absorbs or removes various pesticides, chemicals or particulate suspended matter in the water. When people press the water outlet button, they can take clean water. water. In order to maintain the cleanliness of the water, the activated carbon filter element must be replaced regularly. However, when people use the water filter, they often forget to replace the filter element, and they don't know when to replace the filter element. They often change the filter element only when they feel or even find that the water has a peculiar smell. At this time, the filter element has gradually lost its original quality due to long-term use Filtration function (activated carbon absorbs chemical substances to a saturated state, no longer has adsorption function), and even becomes a hotbed for bacterial growth, making the water quality after "filtration" worse than tap water before filtration, endangering human health.

The purpose of this utility model is to design a water filter with a digital metering and display device.

Below in conjunction with embodiment further illustrate the technology of the present utility model.

Referring to FIG. 1 , a water filter with a digital metering and display device mainly includes a filter tank 10 , a filter element 20 , a base 30 , a base 40 , a cover 50 , an optical sensor flowmeter 60 and a control circuit unit 70 .

Referring to FIG. 2 and FIG. 3 together, the filter tank 10 is a cylinder with one end open, and the filter element 20 is housed in the filter tank 10 . The filter element 20 can be an activated carbon filter element or a wood filter element or a half wood and half activated carbon filter element. A male thread 11 is provided near the opening of the canister 10 , and the canister 10 is locked on the female thread 33 of the base 30 by the male thread 11 .

The seat body 30 is fixed on the base 40 by screws P, and a water inlet 31 and a water outlet 32 are oppositely set on the side edge of the seat body 30, and the water inlet 31 is connected with a water pipe L1, which is used to transport tap water so that the tap water enters the canister 10 And filter through the filter element 20, and the filtered clean water flows out through the water outlet 32.
