Description

Technical Field

[0001] The present application relates to the technical field of water purification equipment, and particularly relates to a faucet water purifier. Background Art

[0002] With the economic development and the improvement of living standards, consumers pay more and more attention to healthy water use and drinking, and have higher and higher requirements for water use. As a device that can filter and purify raw water such as tap water, especially a faucet water purifier that can be fixed to a faucet and directly filter impurities and chlorides in the water when the faucet discharges water, it has been recognized and favored by more and more consumers.

[0003] After the traditional faucet water purifier is installed on the faucet, the water discharged from the faucet must pass through the faucet water purifier for filtration. Therefore, when the user needs to take raw water, it is necessary to remove the faucet water purifier from the faucet and then take the raw water, and the operation is very cumbersome. Moreover, repeatedly disassembling and assembling the faucet water purifier easily causes fatigue of the raw water inlet and inability to tightly connect to the faucet, resulting in water leakage problems caused by poor sealing. To improve the above problems, most of the existing faucet water purifiers are configured with a water path switching structure, which is mainly used to switch between the raw water state and the purified water state. When switched to the raw water state, the raw water discharged from the faucet is directly discharged through the faucet water purifier without filtration. When switched to the purified water state, the raw water discharged from the faucet is filtered by the filtration structure of the faucet water purifier and then discharged. By setting the water path switching structure, it is possible to directly take raw water and purified water without removing the faucet water purifier. However, the existing water path switching structure has more components and a complex water path, resulting in a larger overall volume of the faucet water purifier, a bloated structure, and low convenience in switching the water outlet state. Summary of the Utility Model

[0004] The present application provides a faucet water purifier to improve or solve to a certain extent the technical problems in the existing faucet water purifier, such as more components in the water path switching structure, complex water path, resulting in a larger overall volume of the faucet water purifier, a bloated structure, and low convenience in switching the water outlet state.

[0005] The technical solution adopted by the present application is as follows:

[0006] A faucet water purifier includes a housing, a filter element, and a water path switching unit. The housing has a raw water inlet, a raw water outlet, and a purified water outlet.

The turntable can rotate back and forth relative to the housing between a raw water outlet position and a purified water outlet position. When the turntable rotates from the raw water outlet position towards the purified water outlet position, the raw water valve core closes the raw water outlet while the purified water valve core opens the purified water outlet. When the turntable rotates from the purified water outlet position towards the raw water outlet position, the raw water valve core opens the raw water outlet while the purified water valve core closes the purified water outlet.

[0013] The raw water valve core includes a raw water valve core main body and a raw water plugging and sealing body sleeved on the raw water valve core main body. The raw water valve core main body moves back and forth in the raw water outlet, and closes or opens the raw water outlet through the raw water plugging and sealing body.

The water purification valve core main body includes a water purification valve core shaft and water purification water passing ribs extending outward from the water purification valve core shaft and arranged at intervals. A water purification water passing channel is formed between any two adjacent water purification water passing ribs.

[0014] A raw water valve core return spring is arranged between the raw water valve core and the housing. The raw water valve core return spring is used to reset the raw water valve core from the position of opening the raw water outlet to the position of closing the raw water outlet; and / or, a water purification valve core return spring is arranged between the water purification valve core and the housing.

[0017] Due to the adoption of the above technical solutions, the technical effects achieved by this application are as follows:

[0018] 1. For the faucet water purifier provided by this application, after the faucet is installed in place, the raw water enters the shell through the raw water inlet. On the one hand, the raw water in the shell can be discharged through the raw water outlet, and on the other hand, it can be discharged through the purified water outlet after being filtered by the filter element into purified water. The water path switching unit is used to control the opening and closing states of the purified water outlet and the raw water outlet, control the opening of the raw water outlet while closing the purified water outlet, and control the opening of the purified water outlet while closing the raw water outlet, so that the faucet water purifier can be switched between the state of discharging purified water and the state of discharging raw water. Specifically, when the turntable rotates to the raw water discharging position, the raw water valve core opens the raw water outlet and closes the purified water outlet at the same time. At this time, when the faucet discharges raw water outward, the raw water sequentially passes through the raw water inlet, the raw water channel, and the raw water outlet, so that the faucet water purifier is in the state of discharging raw water; when the turntable rotates to the purified water discharging position, the raw water valve core closes the raw water outlet and opens the purified water outlet at the same time. At this time, when the faucet discharges raw water outward, the raw water sequentially passes through the raw water inlet, the filter element, and the purified water outlet, so that the faucet water purifier is in the state of discharging purified water. Therefore, only by controlling the rotation and switching of the turntable relative to the shell between the raw water discharging position and the purified water discharging position, corresponding actions can be made by the raw water valve core and the purified water valve core, and the switching of the faucet water purifier between the state of discharging raw water and the state of discharging purified water can be realized, meeting the different usage scenarios of raw water and purified water for users, making the overall water path switching structure have fewer components, the water path structure is simple, which is helpful for the miniaturization of the faucet water purifier and saves the production cost of the faucet water purifier, and also greatly improves the operation convenience of switching the water discharging state of the faucet water purifier.

[0019] 2. As a preferred mode of this application, during the rotation of the turntable, the raw water valve core moves linearly in the raw water outlet to open or close the raw water outlet, and the purified water valve core moves linearly in the purified water outlet to open or close the purified water outlet, so that the rotational movement of the turntable is converted into the synchronous linear movement of the raw water valve core and the purified water valve core to control the water discharging state of the faucet water purifier. The structure is simple, easy to implement, and has high reliability. Moreover, when the raw water valve core and the purified water valve core move linearly at the same time, their moving directions are opposite, which is convenient for simplifying the turntable structure, and only a simple driving structure needs to be set on the turntable to realize the reverse movement of the raw water valve core and the purified water valve core.

[0020] 3. As a preferred embodiment of the present application, the rotation center line of the turntable coincides with the central axis of the purified water outlet and is arranged at an interval from the central axis of the raw water outlet, so that the purified water valve core is arranged centrally relative to the turntable and the raw water valve core is arranged eccentrically relative to the turntable, making the overall structure of the water path switching unit compact and occupying a small space. During the rotation of the turntable towards the purified water outlet working position, the purified water valve core is pushed to move linearly by the purified water switching rib to open the purified water outlet. During the rotation of the turntable towards the raw water outlet working position, the raw water valve core is pushed to move linearly by the raw water switching rib to open the raw water outlet, realizing the driving of the raw water valve core and the purified water valve core by the pure mechanical structure of the turntable, with strong reliability.

[0021] 4. As a preferred embodiment of the present application, the limiting convex part and the limiting concave part are in limiting cooperation to limit the rotation of the purified water valve core around the central axis of the purified water outlet, preventing the purified water valve core arranged coaxially with the turntable from rotating along with the rotation of the turntable during the rotation of the turntable, so that the action of opening or closing the purified water outlet by the purified water valve core can be stably and effectively executed.

[0022] 5. As a preferred embodiment of the present application, when the turntable rotates back and forth, it is limited by the stop part to respectively stop with the raw water working position limiting part and the purified water working position limiting part, so that the turntable can only rotate within the limited rotation range, facilitating the user to distinguish the position where the turntable is located. When selecting the water outlet function, it is more directional, and it can quickly distinguish that the turntable needs to be rotated in a certain direction to obtain the required water outlet function.

[0047] In the embodiments of the present application, a faucet water purifier is provided. For the convenience of description and understanding, the following content provided by the present application is all elaborated on the basis of the structure of the product shown in the drawings. Of course, those skilled in the art can understand that the above structure is only a specific example and schematic description, and does not constitute a specific limitation to the technical solution provided by the present application.

[0048] Refer to Figures 1 to 8As shown in the figure, a faucet water purifier provided by the present application includes a housing 1, a filter element 2, and a water path switching unit. The housing 1 has a raw water inlet 11, a raw water outlet 12, and a purified water outlet 13. The filter element 2 is arranged inside the housing 1. The raw water inlet 11 is communicated with the purified water outlet 13 through the filter element 2. A raw water channel 3 that communicates the raw water inlet 11 and the raw water outlet 12 is formed between the filter element 2 and the housing 1. The water path switching unit includes a turntable 4, a raw water valve core 5, and a purified water valve core 6. The turntable 4 can rotate back and forth relative to the housing 1 between a raw water outlet position and a purified water outlet position. When the turntable 4 rotates from the raw water outlet position towards the purified water outlet position, the raw water valve core 5 closes the raw water outlet 12 while the purified water valve core 6 opens the purified water outlet 13. When the turntable 4 rotates from the purified water outlet position towards the raw water outlet position, the raw water valve core 5 opens the raw water outlet 12 while the purified water valve core 6 closes the purified water outlet 13.

[0049] In the faucet water purifier provided by the present application, specifically, the raw water inlet 11 can be butt - joint installed with a faucet. After the faucet is installed in place, raw water enters the housing 1 through the raw water inlet 11. The raw water in the housing 1 can be discharged through the raw water outlet 12 on the one hand, and on the other hand, can be discharged through the purified water outlet 13 after being filtered into purified water by the filter element 2. The water path switching unit is used to control the opening and closing states of the purified water outlet 13 and the raw water outlet 12, closing the raw water outlet 12 while opening the purified water outlet 13, and opening the raw water outlet 12 while closing the purified water outlet 13, so that the faucet water purifier can be switched between the state of discharging purified water and the state of discharging raw water. Specifically, when the turntable 4 rotates to the raw water outlet position, the raw water valve core 5 opens the raw water outlet 12 while the purified water valve core 6 closes the purified water outlet 13. Figure 2 The state shown in the figure is when the turntable 4 is at the raw water outlet position. At this time, when the faucet discharges raw water outward, the raw water sequentially passes through the raw water inlet 11, the raw water channel 3, and the raw water outlet 12, making the faucet water purifier in the state of discharging raw water. When the turntable 4 rotates to the purified water outlet position, the raw water valve core 5 closes the raw water outlet 12 while the purified water valve core 6 opens the purified water outlet 13. Figure 1As shown in the figure, the turntable 4 is in the state at the purified water outlet position. At this time, when the faucet discharges raw water outward, the raw water sequentially passes through the raw water inlet 11, the filter element 2, and the purified water outlet 13 and is discharged, so that the faucet water purifier is in the state of discharging purified water. Therefore, only by controlling the rotation and switching of the turntable 4 relative to the housing 1 between the raw water outlet position and the purified water outlet position, corresponding actions can be made through the raw water valve core 5 and the purified water valve core 6, and the switching between the raw water outlet state and the purified water outlet state of the faucet water purifier can be realized, meeting the different usage scenarios of raw water and purified water for users, making the overall components of the water path switching structure fewer, the water path structure simple, contributing to the miniaturization of the faucet water purifier and saving the production cost of the faucet water purifier, and also greatly improving the operation convenience of switching the water outlet state of the faucet water purifier. Specifically, a drainage structure surrounding the raw water outlet 12 and the purified water outlet 13 can be arranged on the outer side of the housing 1, so that the raw water and the purified water discharged from the raw water outlet 12 and the purified water outlet 13 respectively can be diverted and discharged through the drainage structure.

[0050] As a preferred embodiment of the present application, as Figure 1 and Figure 2 shown, the raw water valve core 5 is located in the raw water outlet 12 and linearly moves along the central axis of the raw water outlet 12 to open or close the raw water outlet 12, the purified water valve core 6 is located in the purified water outlet 13 and linearly moves along the central axis of the purified water outlet 13 to open or close the purified water outlet 13, and the linear moving directions of the raw water valve core 5 and the purified water valve core 6 are opposite at the same time. During the rotation of the turntable 4, the raw water valve core 5 linearly moves in the raw water outlet 12 to open or close the raw water outlet 12, and the purified water valve core 6 linearly moves in the purified water outlet 13 to open or close the purified water outlet 13, so that the rotational motion of the turntable 4 is converted into the synchronous linear motion of the raw water valve core 5 and the purified water valve core 6, realizing the control of the water outlet state of the faucet water purifier. The structure is simple, easy to implement, and has high reliability. Moreover, when the raw water valve core 5 and the purified water valve core 6 linearly move at the same time, their moving directions are opposite. For example, when the raw water valve core 5 moves leftward from the state of closing the raw water outlet 12 shown in Figure 1 to the state of opening the raw water outlet 12 shown in Figure 2 , at the same time, the purified water valve core 6 moves rightward from the state of opening the purified water outlet 13 shown in Figure 1 to the state of closing the purified water outlet 13 shown in Figure 2 , which is convenient for simplifying the structure of the turntable 4, and only a simple driving structure needs to be arranged on the turntable 4 to realize the reverse movement of the raw water valve core 5 and the purified water valve core 6.

[0051] Furthermore, as Figure 1 and Figure 2As shown, the rotation center line of the turntable 4 coincides with the central axis of the purified water outlet 13 and is arranged at an interval from the central axis of the raw water outlet 12. The turntable 4 is provided with a raw water switching rib 41 and a purified water switching rib 42. When the turntable 4 rotates towards the purified water outlet working position, the purified water switching rib 42 pushes the purified water valve core 6 to move linearly to open the purified water outlet 13. When the turntable 4 rotates towards the raw water outlet working position, the raw water switching rib 41 pushes the raw water valve core 5 to move linearly to open the raw water outlet 12. Those skilled in the art can understand that the rotation center line of the turntable 4 coincides with the central axis of the purified water outlet 13, and the purified water valve core 6 is located in the purified water outlet 13, so that the purified water valve core 6 is arranged centrally relative to the turntable 4. The rotation center line of the turntable 4 is arranged at an interval from the central axis of the raw water outlet 12, and the raw water valve core 5 is located in the raw water outlet 12, so that the raw water valve core 5 is arranged eccentrically relative to the turntable 4, making the overall structure of the water path switching unit compact and occupying a small space. During the rotation of the turntable 4 towards the purified water outlet working position, the purified water switching rib 42 pushes the purified water valve core 6 to move linearly to open the purified water outlet 13. During the rotation of the turntable 4 towards the raw water outlet working position, the raw water switching rib 41 pushes the raw water valve core 5 to move linearly to open the raw water outlet 13, realizing the drive of the raw water valve core 5 and the purified water valve core 6 by the pure mechanical structure of the turntable 4, with strong reliability.

[0052] As a preferred embodiment, as Figure 1 、 Figure 2 and Figure 4As shown, the turntable 4 is provided with a rotating plane 43 perpendicular to the rotation center line. The raw water switching rib 41 and the purified water switching rib 42 protrude from the rotating plane 43 along the extending direction of the rotation center line respectively. The raw water switching rib 41 is provided with a raw water switching pushing slope 44, and the purified water switching rib 42 is provided with a purified water switching pushing slope 45. The projections of the raw water switching pushing slope 44 and the purified water switching pushing slope 45 on the rotating plane 43 are arcs around the rotation center line respectively; along the rotation direction of the turntable 4 from the raw water outlet station to the purified water outlet station, the raw water switching pushing slope 44 gradually rises relative to the rotating plane 43, and the purified water switching pushing slope 45 gradually descends relative to the rotating plane 43. Specifically, the raw water switching rib 41 and the purified water switching rib 42 can be respectively constructed as arc structures extending around the central rotation axis of the turntable 4. The raw water switching pushing slope 44 is arranged on the top surface of the raw water switching rib 41, and the purified water switching pushing slope 45 is arranged on the top surface of the purified water switching rib 42. Along the rotation direction of the turntable 4 from the raw water outlet station to the purified water outlet station, the raw water switching pushing slope 44 gradually rises relative to the rotating plane 43, and the purified water switching pushing slope 45 gradually descends relative to the rotating plane 43. When the turntable 4 is located at the raw water outlet station, the top of the raw water switching pushing slope 44 abuts against the raw water valve core 5 and presses the raw water valve core 5 at the position of opening the raw water outlet 12. At this time, the purified water valve core 6 abuts against the rotating plane 43 and does not contact the purified water switching pushing slope 45, and the purified water valve core 6 closes the purified water outlet 13; when the turntable 4 rotates from the raw water outlet station towards the purified water outlet station, the raw water switching rib 41 rotates with the turntable 4, causing the raw water valve core 5 to slide from the top of the raw water switching pushing slope 44 to the bottom of the raw water switching pushing slope 44 until it disengages from the raw water switching pushing slope 44 and abuts against the rotating plane 43. At this time, the raw water valve core 5 closes the raw water outlet 12. During this process, the purified water switching rib 42 rotates with the turntable 4, causing the purified water valve core 6 to slide from the position where it abuts against the rotating plane 43 to the purified water switching pushing slope 45, and then slide from the bottom of the purified water switching pushing slope 45 to the top of the purified water switching pushing slope 45. At this time, the purified water valve core 6 opens the purified water outlet 13; when the turntable 4 rotates from the purified water outlet station towards the raw water outlet station, the purified water switching rib 42 rotates with the turntable 4, causing the purified water valve core 6 to slide from the top of the purified water switching pushing slope 45 to the bottom of the purified water switching pushing slope 45 until it disengages from the purified water switching pushing slope 45 and abuts against the rotating plane 43. At this time, the purified water valve core 6 closes the purified water outlet 13. During this process, the raw water switching rib 41 rotates with the turntable 4, causing the raw water valve core 5 to slide from the position where it abuts against the rotating plane 43 to the raw water switching pushing slope 44, and then slide from the bottom of the raw water switching pushing slope 44 to the top of the raw water switching pushing slope 44. At this time, the raw water valve core 5 opens the raw water outlet 12.

[0053] Since the rotation center line of the turntable 4 coincides with the central axis of the purified water outlet 13, the purified water valve core 6 is arranged centered relative to the turntable 4. Further, during the rotation of the turntable 4, it is possible for the purified water valve core 6 to rotate synchronously with the turntable 4. Therefore, as a preferred embodiment, one of the purified water valve core 6 and the housing 1 is provided with a limiting convex portion, and the other of the two is provided with a limiting concave portion. The limiting convex portion and the limiting concave portion are in limiting cooperation to limit the rotation of the purified water valve core 6 around the central axis of the purified water outlet 13. As Figure 2 , Figure 3 and Figure 6 shown, the embodiment of the present application schematically shows an example in which the purified water valve core 6 is provided with a limiting convex portion 614 and the housing 1 is provided with a limiting concave portion 14. The limiting convex portion 614 and the limiting concave portion 14 are in limiting cooperation, so that the purified water valve core 6 will not rotate self - synchronously with the rotation of the turntable 4. It can only move linearly along the purified water outlet 13 under the action of the purified water switching push - top inclined surface 45, enabling the purified water valve core 6 to stably and effectively perform the action of opening or closing the purified water outlet 13.

[0054] As a preferred implementation manner of the present application, as Figure 3 and Figure 4 shown, the housing 1 is provided with a raw water working position limiting portion 15 and a purified water working position limiting portion 16 arranged at intervals. The turntable 4 is provided with a stop portion 46. When the turntable 4 rotates back and forth, the rotation angle of the turntable 4 is limited by the stop portion 46 respectively abutting against the raw water working position limiting portion 15 and the purified water working position limiting portion 16, so that the turntable 4 can only rotate within the limited rotation range, which is convenient for the user to distinguish the position of the turntable 4. When selecting the water outlet function, it is more directional and can quickly distinguish that the turntable 4 needs to be rotated in a certain direction to obtain the required water outlet function. For example, the rotation angle of the turntable 4 can be limited within a 90° range by the raw water working position limiting portion 15 and the purified water working position limiting portion 16. When the stop portion 46 abuts against the raw water working position limiting portion 15, the turntable 4 is located at the raw water outlet working position. When the turntable 4 rotates 90° and the stop portion 46 abuts against the purified water working position limiting portion 16, at this time the turntable 4 is located at the purified water outlet working position. Of course, the rotation angle of the turntable 4 can also be limited within other appropriate angle ranges by the raw water working position limiting portion 15 and the purified water working position limiting portion 16, such as 60°, 120°, etc.

The purified water valve core main body 61 includes a purified water valve core shaft 611 and purified water water passing ribs 612 extending outward from the purified water valve core shaft 611 and arranged at intervals. A purified water water passing channel is formed between any two adjacent purified water water passing ribs 612. Specifically, when the turntable 4 is located at the raw water outlet working position, the purified water valve core 6 is located at a position where the purified water plugging and sealing body 62 abuts against the housing 1 to close the purified water outlet 13. When the turntable 4 is located at the purified water outlet working position, the purified water valve core 6 is located at a position where the purified water plugging and sealing body 62 is away from the purified water outlet 13 to open the purified water outlet 13. The purified water produced by filtering the raw water in the housing 1 through the filter element 2 flows out of the housing 1 through the purified water water passing channel formed between two adjacent purified water water passing ribs 612,

[0056] As a preferred implementation manner of the present application, as Figure 1 and Figure 2As shown, a raw water valve core return spring 7 is provided between the raw water valve core 5 and the housing 1. The raw water valve core return spring 7 is used to reset the raw water valve core 5 from the position of opening the raw water outlet 12 to the position of closing the raw water outlet 12. Taking the example that the aforementioned turntable 4 pushes the raw water valve core 5 to move linearly through the raw water switching push slope 44, when the turntable 4 rotates towards the raw water outlet station, the raw water valve core 5 gradually opens the raw water outlet 12 and compresses the raw water valve core return spring 7; when the turntable 4 rotates towards the purified water outlet station, the raw water valve core 5 gradually disengages from the raw water switching push slope 44. At this time, the pressure exerted by the raw water valve core 5 on the raw water valve core return spring 7 gradually disappears, so that the raw water valve core return spring 7 gradually resets the raw water valve core 5 towards the position of closing the raw water outlet 12.

[0057] As another preferred embodiment of the present application, as Figure 1 and Figure 2 shown, a purified water valve core return spring 8 is provided between the purified water valve core 6 and the housing 1. The purified water valve core return spring 8 is used to reset the purified water valve core 6 from the position of opening the purified water outlet 13 to the position of closing the raw water outlet 12 of the purified water. Taking the example that the aforementioned turntable 4 pushes the purified water valve core 6 to move linearly through the purified water switching push slope 45, when the turntable 4 rotates towards the purified water outlet station, the purified water valve core 6 gradually opens the purified water outlet 13 and compresses the purified water valve core return spring 8; when the turntable 4 rotates towards the raw water outlet station, the purified water valve core 6 gradually disengages from the purified water switching push slope 45. At this time, the pressure exerted by the purified water valve core 6 on the purified water valve core return spring 8 gradually disappears, so that the purified water valve core return spring 8 gradually resets the purified water valve core 6 towards the position of closing the purified water outlet 13.

[0058] As a preferred embodiment, as Figures 1 to 3 and Figure 7 shown, the housing 1 is provided with a raw water valve core guiding rib 17 surrounding the raw water outlet 12.

One end of the raw water valve core return spring 7 abuts against the housing 1, and the other end is limited in the raw water valve core limiting groove 513 provided on the raw water valve core 5. The raw water valve core guiding rib 17 guides the reciprocating movement of the raw water valve core 5 within the raw water outlet 12 to ensure the stability of the movement process of the raw water valve core 5. Moreover, since the raw water valve core return spring 7 is sleeved on the raw water valve core guiding rib 17, the raw water valve core guiding rib 17 can limit the raw water valve core return spring 7. The other end of the raw water valve core return spring 7 is limited in the raw water valve core limiting groove 513 provided on the raw water valve core 5, so that the raw water valve core limiting groove 513 and the raw water valve core guiding rib 17 can jointly limit the raw water valve core return spring 7 to ensure the stable compression and relaxation of the raw water valve core return spring 7 and prevent the raw water valve core return spring 7 from moving radially.

[0059] As a preferred embodiment, as Figures 1 to 3 and Figure 6 shown, the housing 1 is provided with a water purification valve core guide rib 18 around the water purification outlet 13. The water purification valve core 6 moves within the water purification valve core guide rib 18. The water purification valve core return spring 8 is sleeved on the water purification valve core guide rib 18. One end of the water purification valve core return spring 8 abuts against the housing 1, and the other end is limited within the water purification valve core limit groove 613 provided on the water purification valve core 6. The water purification valve core guide rib 18 guides the reciprocating movement of the water purification valve core 6 within the water purification outlet 13, ensuring the stability of the movement process of the water purification valve core 6. Moreover, since the water purification valve core return spring 8 is sleeved on the water purification valve core guide rib 18, the water purification valve core guide rib 18 can limit the water purification valve core return spring 8. And the other end of the water purification valve core return spring 8 is limited within the water purification valve core limit groove 613 provided on the water purification valve core 6, so that the water purification valve core limit groove 613 can, together with the water purification valve core guide rib 18, limit the water purification valve core return spring 8, ensuring the stable compression and relaxation of the water purification valve core return spring 8 and preventing radial movement of the water purification valve core return spring 8. Specifically, the limit recess 14 in the foregoing embodiment can be provided on the water purification valve core guide rib 18 to facilitate the limit cooperation between the limit protrusion 614 on the water purification valve core 6 and the limit recess 14.

Specifically, the knob 9 can be arranged outside the whole body of the faucet water purifier, facilitating the user to switch the turntable 4 between the raw water outlet position and the purified water outlet position by hand-twisting the knob 9. To make the knob 9 drive the turntable 4 to rotate synchronously when the knob 9 is rotated, the knob 9 and the turntable 4 need to be circumferentially fixed. In a preferred embodiment, the knob 9 and the turntable 4 can be snap-connected to achieve circumferential fixation. Specifically, a card slot 91 can be provided on the knob 9, and a snap protrusion 47 is provided on the turntable 4, and the card slot 91 and the snap protrusion 47 are snap-connected. In another preferred embodiment, the knob 9 is provided with a rotation limit insertion block 92, and the turntable 4 is provided with a rotation limit slot 48. The rotation limit insertion block 92 and the rotation limit slot 48 are inserted and matched to limit the rotation of the knob 9 relative to the turntable 4.
