As shown in fig. 5 to 7, a rotary shaft 21 is formed at one end of the valve core 2, a filtering water delivery groove 201 is formed at one side of the rotary shaft 21, a tap water through notch 202 is formed at the other side corresponding to the rotary shaft 21, a closed-loop sealing strip 22 is arranged around the tap water through notch 202, the closed-loop sealing strip 22 is used for enclosing a pipe cavity water inlet 1101 and a pipe cavity water outlet 1102 under a raw water blocking position and enclosing the pipe cavity water outlet 1102 under a purified water blocking position, the closed-loop sealing strip 22 is embedded on the rotary shaft 21, the rotary shaft 21 is inserted into the pipe cavity 11 from the other end corresponding to the pipe cavity 11, the closed-loop sealing strip 22 is in sealing connection with the inner wall of the pipe cavity 11, the closed-loop sealing strip 22 is made of rubber, and the section of the closed-loop sealing strip 22 is circular under a free state. As shown in fig. 3, in the raw water gear, the tap water through notch 202 is located between the lumen inlet hole 1101 and the lumen outlet hole 1102; as shown in fig. 4, in the water purification position, one end of the filtration water feeding groove 201 is located at the corresponding lower side of the lumen water feeding hole 1101 and the other end of the filtration water feeding groove 201 is axially corresponding to the filtration water feeding hole 103.
The working principle of the utility model is briefly described below: as shown in fig. 3, when the valve core 2 is located at a position corresponding to the raw water gear position relative to the valve housing 1, the tap water flows into the upper portion of the valve housing 1 from the tap water inlet 101, and then enters the pipe cavity 11 through the pipe cavity water inlet 1101, and the tap water through notch 202 is located between the pipe cavity water inlet 1101 and the pipe cavity water outlet 1102, so that the tap water directly reaches the pipe cavity water outlet 1102 through the tap water through notch 202, and then is discharged through the tap water outlet 102 at the lower end of the valve housing 1. When the water purification gear is required to be switched to, the valve core 2 is rotated, the rotating shaft 21 is rotated to the position shown in fig. 4, one end of the filtration water delivery tank 201 is positioned at the corresponding lower side of the pipe cavity water inlet 1101, tap water flows into the inner cavity of the filter core base 4 through the filtration water delivery tank 201 and the filtration water delivery hole 103, water flows into the inner cavity of the filter core cover 6, the water flows into the filter core 5 through the filter core 5, filtered water flows through the lower end of the filter core 5 and is discharged from the water purification outlet at the lower end of the filter core base 4, and as can be seen in fig. 4, the water does not need to enter the valve core 2, and can enter the filter assembly 20 only through simple turning, so that the water flow is smooth, and the water purification output flow is increased. As shown in fig. 5 to 7, since the closed-loop sealing strip 22 is not provided with a fracture, as shown in fig. 3, the closed-loop sealing strip 22 can enclose the lumen water inlet 1101 and the lumen water outlet 1102 at the same time, so that water flow can only flow within the range enclosed by the closed-loop sealing strip 22, after the water flow enters the lumen 11 through the lumen water inlet 1101, the water flow is concentrated and directly flows to the lumen water outlet 1102 through the tap water through notch 202, the water flow path is further simplified, and tap water is prevented from leaking to the filter assembly 20 under the condition of raw water gear. As shown in fig. 4, when the closed-loop sealing strip 22 rotates to the corresponding water purification gear, the closed-loop sealing strip 22 rotates to the lower position, and the closed-loop sealing strip 22 surrounds and seals the lumen water outlet 1102, so that tap water is prevented from leaking through the lumen water outlet 1102 in the water purification gear. As can be seen from the above, the present utility model can realize the switching between the raw water level and the purified water level by only providing one rotary shaft 21 in combination with the closed-loop sealing strip 22, and the raw water level and the purified water level can be closely separated, so that the faucet water purifier of the present utility model has the advantages of simple structure, low cost and stable switching function.
Further, as shown in fig. 5, the other end of the valve core 2 corresponding to the valve core is formed with a coupling portion 24, as shown in fig. 4, the coupling portion 24 protrudes out of the valve housing 1, as shown in fig. 1 to 5, the coupling portion 24 is provided with a waterway switching knob 3, as shown in fig. 5, a sealing ring 23 is arranged between the closed-loop sealing strip 22 and the coupling portion 24, and the sealing ring 23 is sleeved on the rotating shaft 21, that is, the sealing ring 23 is an O-shaped sealing ring. As shown in fig. 4, the sealing ring 23 is in sealing connection with the inner wall of the pipe cavity 11, so that a user can push and dial the waterway switching rotary handle 3 with fingers to enable the waterway switching rotary handle 3 to swing, and the waterway switching rotary handle 3 drives the valve core 2 to rotate, thereby realizing switching between a raw water gear and a purified water gear, and by arranging the sealing ring 23, water leakage at one end of the pipe cavity 11, which is close to the waterway switching rotary handle 3, is avoided.
Further, as shown in fig. 5, a convex key portion 241 is formed on the coupling portion 24, a coupling slot 301 is formed in one end of the waterway switching knob 3, one end of the waterway switching knob 3 is sleeved outside the coupling portion 24, and the convex key portion 241 is adapted to be connected with the coupling slot 301, so that the coupling portion 24 and the waterway switching knob 3 are positioned circumferentially with simple structure.
Further, as shown in fig. 8, the lumen inlet 1101 and the lumen outlet 1102 are offset to one side of the axis of the lumen 11, for example, the lumen inlet 1101 and the lumen outlet 1102 are located at the rear side of the axis of the lumen 11, and the closed-loop sealing strip 22 is easy to surround the lumen inlet 1101 and the lumen outlet 1102 at the same time, so that the distance between the lumen inlet 1101 and the lumen outlet 1102 is shortened, which is beneficial to the water outlet being directly and quickly in the raw water blocking position.
Further, as shown in fig. 8, two lumen inflow holes 1101 are arranged side by side in a direction parallel to the axis of the lumen 11, that is, two lumen outflow holes 1102 are also arranged side by side in a direction parallel to the axis of the lumen 11, so that the water passage sectional area can be increased while avoiding the occurrence of a weak portion of the wall body of the lumen 11 to cause easy deformation of the lumen 11.
Further, as shown in fig. 9, the filtering water delivery hole 103 is located at the upper side of the axis of the lumen 11, so that the filtering water delivery groove 201 located at one side of the rotation shaft 21 can face the filtering water delivery hole 103 when rotated to the upper position, thereby facilitating the clear water path.
