[0017] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: the tube body is installed in the valve seat and connected to the matching hole on the valve seat through the installation device, and then one end of the tube body is fixedly connected to the external faucet elbow through the connecting device. When the faucet needs to discharge purified water, the first water inlet hole and the water outlet are made to correspond to each other by rotating the shell. At this time, water flows into the water storage chamber from the first water inlet hole. When the water flows into the water storage chamber, the filtering device filters impurities in the water flow, and allows the filtered water to flow out from the first water outlet hole, thereby realizing the discharge of purified water from the faucet; when the faucet needs to discharge tap water, the shell is rotated to make the second water inlet hole and the water outlet correspond to each other. At this time, water flows into the second water inlet hole and flows out from the second water outlet hole, thereby realizing the discharge of tap water from the faucet. There is no need to install two faucets on the countertop, and the water discharge mode of tap water and purified water can be switched when one faucet is installed, and the use function is diverse.

[0018] Further effect: the water outlet mode of tap water and purified water can be switched when one faucet is installed. Customers can use tap water and purified water without installing two faucets. It does not require a large installation space, saving installation and use costs.

[0019] Further effect: when the diatomaceous earth ceramic filter element or the ultrafiltration membrane filter element needs to be cleaned, the upper shell and the lower shell are twisted to separate the two through the threaded connection, and then the filter seat is pulled upward to disconnect the connecting pipe from the lower shell, so that the filter element is taken out from the shell, and the impurities on the diatomaceous earth ceramic filter element or the ultrafiltration membrane filter element can be cleaned.

[0020] Further effect: when the shell is rotated, the positioning block slides downward in the installation groove and squeezes the compression spring. When the water outlet corresponds to the position of the first water inlet hole, the compression spring releases elastic potential energy to push the positioning block to engage with one of the positioning holes. At this time, a "click" sound is formed and rotation resistance is formed, thereby realizing the positioning effect. When the water outlet corresponds to the position of the second water inlet hole, the positioning block engages with the other positioning hole.

[0021] Further effect: when the pipe body is placed in the valve seat and needs to be installed, the connecting bolt is passed through the connecting opening and matched with the threaded slot thread, and the pipe body is abutted against the end face of the valve seat through the head of the connecting bolt.

[0022] Further effect: when the other end of the tube body is mounted on the valve seat, the elastic sealing sheet can improve the sealing between the other end of the tube body and the valve seat, and further prevent water leakage when the shell body rotates.

[0023] Further effect: when the water outlet corresponds to the first connecting hole or the second connecting hole on the valve seat, a space is formed for water to be discharged outward. At this time, the water stop plate is pushed by the water flow at the water inlet end to drive the sliding rod to slide to the left on the connecting sleeve, so that the water stop plate and the water stop hole are disengaged, and the water flows into the installation opening from the water stop hole and flows into the water inlet opening on the pipe body from the flow area, so that the water flows out from the water outlet; and when the water outlet corresponds to the closed water groove on the valve seat or does not correspond to other water outlets, the water flow at the other end of the pipe body cannot be discharged outward, so that the pressure in the water inlet opening is increased, and the water flow at the water inlet end can no longer push the water stop plate to move to the left. At this time, the reset spring resets and pushes the water stop plate to slide to the right, thereby closing the water stop hole to further prevent water from continuously pouring into the water inlet opening and causing leakage.

A sealing ring a2 is provided on one side of the connecting positioning groove 14 at one end of the tube body 9. When the tube body 9 is inserted into the water outlet bend of the faucet, the sealing ring a2 can seal the gap between the water outlet bend and one end of the tube body 9, further preventing water from leaking from the gap. The tube body 9 is installed in the water outlet bend of the faucet through the connecting positioning groove 14, and the tube body 9 remains stationary when the shell rotates, so that the position of the water outlet 11 corresponds to the first water inlet 4 and the second water inlet 7.

The connection bolt 16 can also be replaced by a connection screw. When the connection bolt 16 is installed in the connection opening 15 and the matching hole 12, the head of the connection bolt 16 abuts against the end face of the tube body 9 located at the connection opening 15 to seal the connection opening 15. A sealing gasket for improving the sealing between the connection bolt 16 and the connection opening 15 can also be provided at the head of the connection bolt 16. In order to improve the connection stability of the connecting bolt 16 on the lower shell 23, the matching hole 12 can be opened as a hexagonal slot, and a hexagonal nut can be inserted and fixed to the matching slot. The screw portion of the connecting bolt 16 and the hexagonal nut are threadedly matched to achieve fixation between the two, which can improve the stability between the connecting bolt 16 and the lower shell 23 and prevent the connecting bolt 16 from detaching from the lower shell 23.

At this time, water flows from the first water inlet 4 into the water storage chamber 3. When the water flows into the water storage chamber 3, it passes through the ultrafiltration membrane filtration core 2 2. Impurities in the water flow are filtered, and the filtered water flows into the flow hole 19 and flows out to the outflow hole, so that the filtered water flows out from the first water outlet 5, thereby realizing the outlet of purified water from the faucet; when the faucet needs to be used to discharge tap water, the lower shell 23 is held by hand and rotated so that the second water outlet 11 faces downward, and the second water inlet 7 corresponds to the position of the water outlet 11. At this time, the water flows into the second water inlet 7 and flows out from the second water outlet 8, thereby realizing the outlet of tap water from the faucet. There is no need to install two faucets on the countertop, and the outlet modes of tap water and purified water can be switched when one faucet is installed, and the use functions are diverse;

[0055] When the housing is rotated, the positioning block 28 slides downward in the installation slot 27 and squeezes the compression spring 29. When the water outlet 11 corresponds to the position of the first water inlet hole 4, the compression spring 29 releases elastic potential energy to push the positioning block 28 to engage with one of the positioning holes 26, at which time a "click" sound is formed and rotation resistance is formed, thereby achieving the positioning effect. When the water outlet 11 corresponds to the position of the second water inlet hole 7, the positioning block 28 engages with the other positioning hole 26;

[0056] When it is necessary to clean the diatomaceous earth ceramic filter core 18 or the ultrafiltration membrane filter core 22, twist the upper shell 24 and the lower shell 23 through the threaded connection to separate the two, then pull up the filter seat 17 to disconnect the connecting pipe 20 from the lower shell 23, so that the filter core is taken out from the shell, and the impurities on the diatomaceous earth ceramic filter core 18 or the ultrafiltration membrane filter core 22 can be cleaned;

[0057] The elastic sealing sheet 25 can improve the sealing performance between the other end of the tube body 9 and the valve seat 1 when the other end of the tube body 9 is installed on the valve seat 1, and further prevent water leakage when the housing rotates.
