Description

Technical Field

[0001] This application relates to the field of water purification equipment technology, specifically to a faucet water purifier. Background Technology

[0002] A faucet water purifier is a device that can be directly fixed to a faucet and filter impurities in tap water as it flows out. It is gaining increasing recognition and favor among consumers.

[0003] Faucet water purifiers typically feature a water path switching mechanism. This mechanism switches between raw water and purified water output modes. When switched to raw water mode, the tap water flows directly through the purifier without being filtered by the filter cartridge. When switched to purified water mode, the tap water passes through the purifier's filter cartridge before being discharged. This switching mechanism allows for direct access to both raw and purified water from the faucet, enhancing the user experience. Most commercially available faucet water purifiers have a water circuit switching mechanism consisting of a knob, a turntable, and a switching valve. The switching valve contains a raw water valve core and a purified water valve core. The knob rotates the turntable, which in turn pushes the raw water valve core and purified water valve core back and forth. The raw water valve core opens the raw water outlet while the purified water valve core closes the purified water outlet, thus the faucet water purifier is dispensing raw water; conversely, the raw water valve core closes the raw water outlet while the purified water valve core opens the purified water outlet, thus the faucet water purifier is dispensing purified water. However, this type of water circuit switching mechanism has many components, occupies a large installation space, and makes the faucet water purifier bulky, increasing product packaging and transportation costs. Furthermore, the operation of the water circuit switching mechanism involves not only the rotation of the turntable but also the translational movement of the raw water valve core and purified water valve core, resulting in a complex process, lower reliability, and a higher probability of failure. Utility Model Content

[0004] This application provides a faucet water purifier to improve the technical problems of existing faucet water purifiers, such as the large number of parts in the water circuit switching structure, the large size of the whole machine, the low reliability, and the high probability of damage.

[0005] The technical solution adopted in this application is as follows:

[0006] A faucet water purifier includes a filtration unit and a switching component. The filtration unit includes a filter cartridge holder, a filter bottle, and a filter cartridge. The filter bottle is connected to the filter cartridge holder to form a filtration chamber for accommodating the filter cartridge. The filter cartridge holder has a raw water inlet and a raw water outlet respectively connected to the filtration chamber, and a purified water outlet for discharging purified water. The switching component has a raw water sealing body and a purified water sealing body. The switching component can rotatably switch between a raw water outlet position and a purified water outlet position. When the switching component is located at the raw water outlet position, it causes the raw water sealing body to open the raw water outlet and the purified water sealing body to close the purified water outlet. When the switching component is located at the purified water outlet position, it causes the raw water sealing body to close the raw water outlet and the purified water sealing body to open the purified water outlet.

[0007] The faucet water purifier in this application also has the following additional technical features:

[0008] The filter cartridge holder is provided with a purified water outlet section, and the purified water outlet section is provided with a purified water outlet channel that is connected to the water outlet port of the filter cartridge. The purified water outlet is provided in the purified water outlet section. The switching component includes a first rotating shaft section, and the purified water sealing body is provided in the first rotating shaft section. The first rotating shaft section rotates in the purified water outlet channel to open or close the purified water outlet by the purified water sealing body.

[0009] The first rotating shaft is provided with a water passage, which includes a water inlet for connecting to the water outlet port and a water outlet for connecting to the purified water outlet. When the switching component is located at the purified water outlet position, the water outlet port is connected to the purified water outlet through the water passage.

[0010] The water inlet is located at one end of the first rotating shaft near the filter element, and the water outlet and the purified water sealing body are arranged circumferentially on the side of the first rotating shaft. When the switching member is located at the purified water outlet position, the water outlet and the purified water outlet are arranged opposite each other to achieve communication. When the switching member is located at the raw water outlet position, the water outlet and the purified water outlet are misaligned and separated by the purified water sealing body.

[0011] The filter cartridge seat is provided with a raw water outlet, which surrounds and is connected to the outside of the purified water outlet. The filter chamber is located outside the raw water outlet, and the raw water outlet is located at the raw water outlet. The raw water outlet and the purified water outlet form a drainage channel for the raw water outlet and the purified water outlet to drain water outward. The switching component also includes a second rotating shaft coaxially connected to the first rotating shaft. The raw water sealing body is located on the side of the second rotating shaft. When the switching component is located at the raw water outlet position, the raw water sealing body is misaligned with the raw water outlet to open the raw water outlet.

[0012] The filter cartridge holder is provided with a plurality of purified water outlets and a plurality of raw water outlets arranged at intervals along the rotation direction of the switching component; the switching component is provided with a plurality of raw water sealing bodies and a plurality of purified water sealing bodies.

[0013] The switching component is provided with multiple water purification sealing body mounting slots and multiple raw water sealing body mounting slots. The water purification sealing bodies are installed in the water purification sealing body mounting slots one by one, and the raw water sealing bodies are installed in the raw water sealing body mounting slots one by one.

[0014] One of the switching component and the filter cartridge seat is provided with a guide protrusion, and the other is provided with an arc-shaped guide groove. The guide protrusion and the guide groove slide together to guide the switching component to rotate. The inner wall of one end of the guide groove abuts against the guide protrusion to stop the switching component at the raw water outlet position. The inner wall of the other end of the guide groove abuts against the guide protrusion to stop the switching component at the purified water outlet position.

[0015] The faucet water purifier also includes a water outlet arm, which is connected to the filter bottle on two opposite sides of the filter cartridge seat. The switching element is located between the water outlet arm and the filter cartridge seat. The water outlet arm has a water outlet channel, through which both the raw water outlet and the purified water outlet drain water. The water outlet arm has a rotating hole, and the switching element is rotatably located within the rotating hole.

[0016] The faucet water purifier also includes a knob for rotating the switching component. The knob is connected to the switching component through the rotating hole. The outer surface of the water outlet arm is provided with a recessed cavity facing the filter cartridge seat. The rotating hole is located in the recessed cavity, and the knob is embedded in the recessed cavity.

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

[0018] 1. The faucet water purifier provided in this application is installed after the faucet. Raw water enters the filter chamber through the raw water inlet. The raw water in the filter chamber can be discharged through the raw water outlet or filtered into purified water through the filter element and discharged through the purified water outlet. The switching component is used to switch the opening and closing states of the purified water outlet and the raw water outlet. Specifically, the switching component is rotatable and has a raw water sealing body and a purified water sealing body. When the switching component is rotated to the raw water outlet position, the raw water sealing body opens the raw water outlet while the purified water sealing body closes the purified water outlet. At this time, when the faucet discharges raw water, the raw water is discharged sequentially through the raw water inlet, the filter chamber, and the raw water outlet, so that the faucet water purifier is in the raw water discharge state. When the switching component is rotated to the purified water outlet position, the raw water sealing body closes the raw water outlet while the purified water sealing body opens the purified water outlet. At this time, when the faucet discharges raw water, the raw water is discharged sequentially through the raw water inlet, the filter chamber, the filter element, and the purified water outlet, so that the faucet water purifier is in the purified water discharge state. Therefore, only the switching mechanism needs to be controlled to meet the user's different needs for raw water and purified water. Moreover, the switching mechanism has a simple structure with few parts. It rotates between the raw water outlet and the purified water outlet, causing the raw water seal and the purified water seal to rotate synchronously. This allows the faucet water purifier to switch between raw water and purified water output states. It is easy to install, occupies little space, and has a more consistent and coordinated overall design, resulting in a smaller faucet water purifier and a lower risk of damage.

[0019] 2. As a preferred embodiment, the water outlet section is provided with a water outlet channel that connects to the water outlet port of the filter element. The water outlet is located in the water outlet section. When the water outlet is opened by the water sealing body, the purified water discharged from the filter element flows through the water outlet channel to the water outlet. When the water outlet is closed by the water sealing body, the purified water in the water outlet channel cannot be discharged, thereby switching the faucet water purifier to the raw water output state. The first rotating shaft opens or closes the water outlet by rotating within the water outlet channel. The water outlet section and the first rotating shaft section rotate in coordination to restrict the first rotating shaft section within its rotational freedom, ensuring reliable operation of the switching component.

[0020] 3. As a preferred embodiment, the first rotating shaft is provided with a water passage. The water passage is used to connect the water outlet of the filter element with the purified water outlet. When the first rotating shaft is located at the purified water outlet position, the purified water discharged from the water outlet of the filter element enters the purified water outlet channel and then enters the water passage. With the guidance of the water passage, it flows towards the purified water outlet. Therefore, the first rotating shaft is not only used to drive the purified water sealing body to rotate and change the water outlet state of the faucet water purifier, but also to guide the purified water from the filter element to the purified water outlet. A single component integrates multiple functions, which helps to simplify the structure and improve the structural compactness.

[0021] 4. As a preferred embodiment, the raw water outlet surrounds the purified water outlet, forming a coaxial structure with simple and compact design. When purified water is discharged from the purified water outlet, it is discharged through the drainage channel between the raw water outlet and the purified water outlet; similarly, when raw water is discharged from the raw water outlet, raw water is also discharged through the drainage channel between the raw water outlet and the purified water outlet. The second rotating shaft is also coaxially arranged with the first rotating shaft, and both are structurally adapted to the raw water outlet and the purified water outlet, respectively. This allows the first rotating shaft to rotate along the inner wall of the purified water outlet while the second rotating shaft rotates along the inner wall of the raw water outlet, thereby switching the positions of the raw water seal and the purified water seal to change the opening and closing states of the raw water outlet and the purified water outlet.

[0022] 5. As a preferred method, the filter cartridge is provided with multiple raw water outlets and multiple purified water outlets. Correspondingly, multiple raw water sealing bodies and multiple purified water sealing bodies can be set on the switching component. When the switching component is located at the raw water outlet position, multiple raw water outlets discharge raw water together. When the switching component is located at the purified water outlet position, multiple purified water outlets discharge purified water together. This helps to increase the water output per unit time and achieve high flow rate water output from the faucet water purifier.

[0023] 6. As a preferred embodiment, the sliding engagement between the guide protrusion and the guide groove can, on the one hand, guide the switching component to rotate reliably between the raw water outlet and the purified water outlet, ensuring operational stability. On the other hand, it can limit the rotation angle of the switching component, allowing it to rotate back and forth within a set angle range. When the inner wall of one end of the guide groove abuts against the guide protrusion, the switching component is positioned at its rotation limit at one end. At this point, the switching component is stopped and confined to the raw water outlet, providing the user with a notification that the switching component has been rotated to the raw water outlet position, thus preventing excessive rotation of the switching component. When the inner wall of the other end of the guide groove abuts against the guide protrusion, the switching component is positioned at its rotation limit at the other end. At this point, the switching component is stopped and confined to the purified water outlet position, providing the user with a notification that the switching component has been rotated to the purified water outlet position, thus preventing excessive rotation of the switching component.

[0047] In the embodiments of this application, a faucet water purifier is provided. For ease of explanation and understanding, the following content provided in this application is based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is only a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0048] Reference Figures 1 to 7As shown, the faucet water purifier provided in this application includes a filtration unit and a switching component 5. The filtration unit includes a filter cartridge holder 1, a filter bottle 2, and a filter cartridge 3. The filter bottle 2 is connected to the filter cartridge holder 1 to form a filtration chamber 4 accommodating the filter cartridge 3. The filter cartridge holder 1 has a raw water inlet 11 and a raw water outlet 12 respectively communicating with the filtration chamber 4, and a purified water outlet 13 for discharging purified water. The switching component 5 has a raw water sealing body 6 and a purified water sealing body 7. The switching component 5 can rotatably switch between a raw water outlet position and a purified water outlet position. Figure 2 As shown, the switching element 5 is located at the raw water outlet position, causing the raw water sealing body 6 to open the raw water outlet 12 and the purified water sealing body 7 to close the purified water outlet 13; Figure 1 As shown, the switching element 5 is located at the purified water outlet position, causing the raw water sealing body 6 to close the raw water outlet 12 and the purified water sealing body 7 to open the purified water outlet 13.

[0049] The faucet water purifier provided in this application can be installed by connecting the raw water inlet 11 to the faucet. For example, most common faucets have external threads at the outlet end. Therefore, a connector with internal threads can be installed inside the raw water inlet 11, allowing the connector and the faucet to be connected by threads. After the faucet water purifier is installed on the faucet, when the faucet is turned on, the tap water flows through the raw water inlet 11 into the filter chamber 4. The raw water in the filter chamber 4 can be discharged through the raw water outlet 12, or filtered into purified water by the filter element 3 and discharged through the purified water outlet 13.

[0050] The switching element 5 is used to switch the opening and closing states of the purified water outlet 13 and the raw water outlet 12. The switching element 5 is rotatable and includes a raw water sealing body 6 and a purified water sealing body 7. When the switching element 5 rotates to the raw water outlet position, the raw water sealing body 6 opens the raw water outlet 12 while the purified water sealing body 7 closes the purified water outlet 13. At this time, when the faucet discharges raw water, the raw water passes through the raw water inlet 11, the filter chamber 4, and the raw water outlet 12 sequentially, putting the faucet water purifier in the raw water discharge state. When the switching element 5 rotates to the purified water outlet position, the raw water sealing body 6 closes the raw water outlet 12 while the purified water sealing body 7 opens the purified water outlet 13. At this time, when the faucet discharges raw water, the raw water passes through the raw water inlet 11, the filter chamber 4, the filter element 3, and the purified water outlet 13 sequentially, putting the faucet water purifier in the purified water discharge state. Therefore, it is only necessary to control the switching element 5 according to the different usage needs of raw water and purified water. Moreover, the switching component 5 has a simple structure and few parts. It can rotate between the raw water outlet and the purified water outlet, causing the raw water seal 6 and the purified water seal 7 to rotate synchronously. This allows the faucet water purifier to switch between raw water and purified water output states. It is easy to install and occupies little space. The overall design is more consistent and coordinated, resulting in a smaller faucet water purifier size and a lower risk of damage.

[0051] In a preferred embodiment, to improve the sealing effect of the raw water seal 6 and the purified water seal 7 on the raw water outlet 12 and the purified water outlet 13 respectively, the raw water seal 6 and the purified water seal 7 can be made of flexible silicone rubber with good elasticity.

[0052] As a preferred embodiment of this application, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the filter cartridge holder 1 is provided with a purified water outlet 14, the purified water outlet 14 is provided with a purified water outlet channel 15 that is connected to the water outlet port of the filter cartridge 3, the purified water outlet 13 is provided in the purified water outlet 14, the switching component 5 includes a first rotating shaft 51, the purified water sealing body 7 is provided in the first rotating shaft 51, the first rotating shaft 51 rotates in the purified water outlet channel 15 to open or close the purified water outlet 13. Specifically, the water outlet port of filter element 3 can be connected to one end of the purified water outlet section 14, and the first rotating shaft section 51 is inserted into the purified water outlet channel 15 from the other end of the purified water outlet section 14. Since the purified water outlet 13 is located in the purified water outlet section 14, when the purified water sealing body 7 opens the purified water outlet 13, the purified water filtered and discharged by filter element 3 flows through the purified water outlet channel 15 to the purified water outlet 13. When the purified water sealing body 7 closes the purified water outlet 13, the purified water in the purified water outlet channel 15 cannot be discharged, thereby switching the faucet water purifier to the original water output state. The first rotating shaft section 51 rotates in the purified water outlet channel 15 to open or close the purified water outlet 13. The purified water outlet section 14 and the first rotating shaft section 51 rotate in cooperation to restrict the first rotating shaft section 51 within the degree of rotational freedom, ensuring that the switching component 5 works reliably.

[0053] As a preferred embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the first rotating shaft portion 51 is provided with a water passage 52, which includes a water inlet 521 connecting to the water outlet port and a water outlet 522 connecting to the purified water outlet 13. When the switching component 5 is located at the purified water outlet position, the water outlet port is connected to the purified water outlet 13 through the water passage 52. Those skilled in the art will understand that when the first rotating shaft portion 51 is located at the purified water outlet position, the purified water discharged from the water outlet port of the filter element 3 enters the purified water outlet channel 15 and then enters the water passage 52. Guided by the water passage 52, it flows towards the purified water outlet 13. Therefore, the first rotating shaft portion 51 not only drives the purified water sealing body 7 to rotate and change the water outlet state of the faucet water purifier, but also guides the purified water from the filter element 3 to the purified water outlet 13. A single component integrates multiple functions, which helps to simplify the structure and improve structural compactness.

[0054] Furthermore, such as Figure 1 and Figure 3 As shown, the water inlet 521 is located at one end of the first rotating shaft 51 near the filter element 3. The water outlet 522 and the water purification sealing body 7 are arranged circumferentially on the side of the first rotating shaft 51, such that when the first rotating shaft 51 rotates within the water purification outlet channel 15, one of the water purification sealing body 7 and the water outlet 522 may correspond to the water purification outlet 13. When the water purification sealing body 7 corresponds to the water purification outlet 13, it closes the water purification outlet 13; when the water outlet 522 corresponds to the water purification outlet 13, purified water can be discharged from the water purification outlet 13. Figure 1 and Figure 3 As shown, when the switching component 5 is located at the purified water outlet position, the water outlet 522 and the purified water outlet 13 are arranged opposite each other to achieve communication; Figure 2 and Figure 3 As shown, when the switching component 5 is located at the raw water outlet station, the water outlet 522 is misaligned with the purified water outlet 13 and separated by the purified water sealing body 7. At this time, the purified water sealing body 7 closes the purified water outlet 13.

[0055] As a preferred embodiment, such as Figure 1 , Figure 3 , Figure 4 and Figure 7As shown, the filter cartridge seat 1 is provided with a raw water outlet 16, which surrounds and connects to the outside of the purified water outlet 14. The filter chamber 4 is located outside the raw water outlet 16, and the raw water outlet 12 is provided on the raw water outlet 16. The raw water outlet 16 and the purified water outlet 14 form a drainage channel 17 for the raw water outlet 12 and the purified water outlet 13 to drain water outward. The switching component 5 also includes a second rotating shaft 53 coaxially connected to the first rotating shaft 51. The raw water sealing body 6 is provided on the side of the second rotating shaft 53, so that when the switching component 5 is located at the raw water outlet position, the raw water sealing body 6 is misaligned with the raw water outlet 12, thereby opening the raw water outlet 12. Figure 2 As shown, when the switching component 5 is in the raw water outlet position, the raw water sealing body 6 closes the raw water outlet 12; Figure 1 As shown, when the switching component 5 is in the purified water outlet position, the raw water seal 6 is misaligned with the raw water outlet 12, thus opening the raw water outlet 12. The raw water outlet 16 surrounds the purified water outlet 14, forming a coaxial structure with a simple and compact design. When purified water is discharged from the purified water outlet 13, purified water is discharged through the drainage channel 17 between the raw water outlet 16 and the purified water outlet 14. When purified water is discharged from the raw water outlet 12, raw water is also discharged through the drainage channel 17 between the raw water outlet 16 and the purified water outlet 14. The second rotating shaft 53 is also arranged coaxially with the first rotating shaft 51. The two are respectively adapted to the structure of the raw water outlet 16 and the purified water outlet 14. While the first rotating shaft 51 rotates along the inner wall of the purified water outlet 14, the second rotating shaft 53 rotates along the inner wall of the raw water outlet 16, thereby switching the positions of the raw water sealing body 6 and the purified water sealing body 7 to change the opening and closing state of the raw water outlet 12 and the purified water outlet 13.

[0056] In a preferred embodiment of this application, the filter cartridge holder 1 is provided with a plurality of purified water outlets 13 and a plurality of raw water outlets 12 spaced apart along the rotation direction of the switching member 5; the switching member 5 is provided with a plurality of raw water sealing bodies 6 and a plurality of purified water sealing bodies 7. Specifically, as Figure 1 and Figure 2As shown, an embodiment is illustrated where the purified water outlet section 14 has two purified water outlets 13 and the raw water outlet section 16 has two raw water outlets 12. The two purified water outlets 13 are symmetrically arranged, and the two raw water outlets 12 are also symmetrically arranged. Correspondingly, two purified water sealing bodies 7 are provided on the first rotating shaft section 51, and two raw water sealing bodies 6 are provided on the second rotating shaft section 53. When the switching element 5 is in the raw water outlet position, the two raw water outlets 12 discharge raw water together, and the two purified water outlets 13 are closed by the two purified water sealing bodies 7; when the switching element 5 is in the purified water outlet position, the two purified water outlets 13 discharge purified water together, and the two raw water outlets 12 are closed by the two raw water sealing bodies 6. Therefore, this design helps to increase the water output per unit time, achieving a high flow rate for the faucet water purifier.

[0057] Furthermore, such as Figure 3 As shown, the switching component 5 is provided with multiple purified water sealing body mounting slots 511 and multiple raw water sealing body mounting slots 531. The purified water sealing bodies 7 are installed one-to-one in the purified water sealing body mounting slots 511, and the raw water sealing bodies 6 are installed one-to-one in the raw water sealing body mounting slots 531, so as to ensure that the raw water sealing bodies 6 and purified water sealing bodies 7 have a stable relative fixed state with the switching component 5, so that the switching component 5 can reliably drive the raw water sealing bodies 6 and purified water sealing bodies 7 to rotate and switch positions during rotation.

[0058] As a preferred embodiment of this application, such as Figure 1 , Figure 3 and Figure 5As shown, the switching component 5 is provided with a guide protrusion 512, and the filter element seat 1 is provided with an arc-shaped guide groove 18. The guide protrusion 512 and the guide groove 18 slide together to guide the switching component 5 to rotate. The inner wall of one end of the guide groove 18 abuts against the guide protrusion 512 to stop the switching component 5 at the raw water outlet position, and the inner wall of the other end of the guide groove 18 abuts against the guide protrusion 512 to stop the switching component 5 at the purified water outlet position. Specifically, an embodiment is shown where the guide protrusion 512 is located at the shaft end of the first rotating shaft portion 51 and the guide groove 18 is located within the purified water outlet portion 14. Those skilled in the art will understand that the sliding fit between the guide protrusion 512 and the guide groove 18, on the one hand, guides the switching member 5 to reliably rotate between the raw water outlet position and the purified water outlet position, ensuring operational stability; on the other hand, it limits the rotation angle of the switching member 5, allowing it to rotate back and forth within a set included angle range. The inner wall of one end of the guide groove 18 is flush with the guide protrusion 512. When the two parts abut against each other, the switching element 5 is positioned at the rotation limit of one end. At this time, the switching element 5 is stopped and limited to the raw water outlet position, giving the user a prompt that the switching element 5 has been rotated to the raw water outlet position, thus preventing the switching element 5 from rotating excessively. When the inner wall of the other end of the guide slide 18 abuts against the guide protrusion 512, the switching element 5 is positioned at the rotation limit of the other end. At this time, the switching element 5 is stopped and limited to the purified water outlet position, giving the user a prompt that the switching element 5 has been rotated to the purified water outlet position, thus preventing the switching element 5 from rotating excessively.

[0059] In an alternative embodiment, the guide protrusion 512 may be disposed on the filter element seat 1, and the guide groove 18 may be disposed on the switching member 5.

[0060] As a preferred embodiment of this application, such as Figure 1 and Figure 2 As shown, the faucet water purifier also includes a water outlet arm 8, which is connected to the filter bottle 2 on two opposite sides of the filter cartridge seat 1. A switching element 5 is disposed between the water outlet arm 8 and the filter cartridge seat 1. The water outlet arm 8 has a water outlet channel 81 through which both the raw water outlet 12 and the purified water outlet 13 drain water. The water outlet arm 8 has a rotating hole 82, and the switching element 5 is rotatably disposed within the rotating hole 82. Specifically, in the embodiment where the raw water outlet section 16 and the purified water outlet section 14 form a drainage channel 17 for the raw water outlet 12 and the purified water outlet 13 to drain water, the water outlet channel 81 of the water outlet arm 8 can communicate with the drainage channel 17, allowing raw water and purified water to enter the water outlet channel 81 after being discharged from the drainage channel 17. The rotating hole 82 of the water outlet arm 8 confines the switching element 5 within its rotational freedom, ensuring reliable rotation of the switching element 5. In addition, a sealing body can be installed between the switching component 5 and the water outlet arm 8 to prevent water leakage from the rotating hole 82.

[0061] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, the faucet water purifier also includes a knob 9 for rotating the switching element 5. The knob 9 is connected to the switching element 5 through the rotating hole 82. The outer surface of the water outlet arm 8 has a recessed cavity 83 facing the filter element seat 1. The rotating hole 82 is located in the recessed cavity 83, and the knob 9 is embedded in the recessed cavity 83. By setting the knob 9, the user can rotate the switching element 5 by operating the knob 9, improving the ease of operation. Specifically, the knob 9 can have a plugging protrusion 91, and the switching element 5 can have a slot 54. The plugging protrusion 91 and the slot 54 can be connected by a rectangular cross-section, so that the switching element 5 is relatively fixed to the knob 9 in the direction of rotation. The rotating hole 82 is located in the recessed cavity 83, and the knob 9 is embedded in the recessed cavity 83, so that at least a part of the knob 9 is hidden in the recessed cavity 83, preventing the knob 9 from protruding outward from the filter element seat 1, making the faucet water purifier more compact and smaller in size.
