As shown in Figure 1, a household filtering faucet for removing fluoride pollution from groundwater includes a water inlet pipe 1, a faucet shell 9 with a hollow interior and forming a faucet inner cavity 6, and a water outlet pipe 12, one end of the water inlet pipe 1 extends into the faucet shell 9 and is connected with the faucet inner cavity 6, and a valve 5 for opening or closing the water flow channel therein is provided on the tube wall of the water inlet pipe 1 located in the faucet inner cavity 6, a switch 4 for rotating the valve 5 is provided on the outer wall of the faucet shell 9, a filtering mechanism for filtering water flowing into the water inlet pipe 1 is provided in the faucet inner cavity 6, and one end of the water outlet pipe 12 extends into the faucet inner cavity 6 and is connected with the filtering mechanism.

In one or more embodiments of the utility model, the filtering mechanism includes a filter element and a central water pipe 11, the central water pipe 11 is arranged in the filter element, and a plurality of water guide holes 10 are arranged on the tube wall of the central water pipe 11, one end of the central water pipe 11 is connected with one end of the outlet pipe 12 extending into the faucet housing 9, and the other end of the central water pipe 11 is sealed. By arranging the central water pipe 11 in the filter element, the water entering the faucet inner cavity 6 can enter the central water pipe 11 from the water guide holes 10 after passing through the filtering mechanism, complete the filtration of groundwater, and be discharged through the outlet pipe 12.

It should be pointed out that the other end of the water pipe 11 is closed to ensure that the water flow must be purified by the filter element before flowing out.

In one or more embodiments of the utility model, the filter element includes a water-permeable filter element rod 7 and a water-permeable filter element cladding 8, the central water pipe 11 is arranged in the filter element rod 7, and the filter element cladding 8 is arranged on the surface of the filter element rod 7. By arranging the filter element rod 7 and the filter element cladding 8, the groundwater entering from the water inlet pipe 1 can penetrate into the filter element cladding 8 and the filter element rod 7 due to the pressure. The filter element cladding 8 has a strong dirt-receiving capacity and can remove sediment and other substances in the water to prevent the filter element rod 7 from being blocked by sediment, and the filter element rod 7 can effectively reduce the fluoride content of the groundwater.

In the embodiment of the utility model, the filter element rod 7 is a zeolite carbon rod composite filter element, and the filter element cladding 8 is a folded PP cotton filter element, which can ensure that water flows in sequentially, first removing sediment and then removing fluorine.

In the embodiment of the utility model, the switch 5 is connected to the valve 4 through a connecting rod, and the switch can be turned to drive the valve 4 to adjust its opening through the connecting rod. When the valve 5 is opened, the valve 5 can ensure that water flows from the water inlet pipe 1 into the faucet cavity 6.

Optionally, in one or more embodiments of the utility model, the central water pipe 11 is integrally formed with the water outlet pipe 12. By integrally forming the central water pipe 11 and the water outlet pipe 12, on the one hand, it is relatively easy to install, and on the other hand, it avoids water leakage at the connection between the two, improves the service life, and has a higher overall structural strength.

In one or more embodiments of the present invention, a plurality of the water guide holes 10 are evenly arranged in an array on the wall of the central water guide tube 11. By evenly arranging the water guide holes 10 in an array on the wall of the central water guide tube 11, filtered water can enter the central water guide tube 11 more evenly, avoiding local pressure difference from causing damage to the filter element rod 7 and the filter element cladding 8 of the filter mechanism, which is beneficial to prolonging the service life of the filter element rod 7 and the filter element cladding 8.

By providing the threaded joint 2 and the fixed base 3, the faucet housing 9 can be conveniently fixed to an external carrier, and the installation is fastened, which is convenient for installation and use.

Optionally, in one or more embodiments of the present invention, the faucet housing 9 and the fixed base 3 are arranged perpendicular to each other. By arranging the faucet housing 9 and the fixed base 3 perpendicular to each other, the filtering effect can be better.

When in use, turn on the switch 4, open the valve 5, and guide the fluorine-contaminated groundwater with a certain pressure into the faucet cavity 6 through the water inlet pipe 1. When the fluorine-contaminated groundwater fills the entire faucet cavity 6, due to the effect of pressure, the pressurized fluorine-contaminated groundwater slowly penetrates into the filter element cladding 8 and then penetrates into the filter element rod 7. The purified groundwater is gathered into the central water pipe 11 through the water guide hole 10 and flows out from the clean water outlet pipe 12 to obtain purified and defluorinated drinking water.

Table 1 below is a comparison of the use effects and costs of a household filtration faucet for removing fluoride pollution from groundwater, a nanofiltration device, and a reverse osmosis membrane device according to the utility model:

Table 1 Comparison of zeolite carbon rod composite filter faucet with nanofiltration and reverse osmosis devices

From the above comparison, it can be seen that although the fluoride removal rate of the faucet using the zeolite carbon rod composite filter is lower than that of the nanofiltration and reverse osmosis membrane, the treated groundwater can also meet the requirements of domestic drinking water, and from the perspective of use cost, the use cost of the faucet using the zeolite carbon rod composite filter is only 1/5 of that of the nanofiltration device and the reverse osmosis membrane device, which is affordable for the people in underdeveloped areas. Therefore, from the perspective of economic applicability, the household filtering faucet for removing fluoride pollution in groundwater has important application value and can solve the drinking water safety problem for the people in remote fluoride-contaminated groundwater areas.

The utility model of a household filtering faucet for removing fluoride pollution in groundwater is provided with a filter element rod 7 and a filter element cladding 8 in the inner cavity 6 of the faucet, and a central water guide pipe 11 with a water guide hole 10 is provided in the filter element rod 7. Groundwater enters the inner cavity 6 of the faucet through the water inlet pipe 1, and penetrates into the filter element cladding 8 and the filter element rod 7 due to the pressure. The filter element cladding 8 has a strong pollution-receiving capacity, and can remove sediment and other substances in the water to prevent the filter element rod 7 from being blocked by sediment. The filter element rod 7 can effectively reduce the fluoride content of groundwater. The fluoride content of the filtered water is low, and it can be used for washing and drinking, which can effectively reduce the incidence of fluoride diseases such as dental fluorosis and improve the quality of drinking water for ordinary people. The filter element is small but removable and replaceable, economical and convenient to use.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
