Description

Technical Field

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

[0002] As consumers place increasing emphasis on healthy water and drinking water, their requirements for water quality are also rising. Water purifiers, as devices that can filter and purify tap water and other raw water sources, especially faucet water purifiers that are fixed to the faucet and directly filter impurities and chlorine from the water as it flows out, are gaining increasing recognition and favor among consumers.

[0003] Most existing faucet water purifiers are equipped with a water path switching mechanism. This mechanism is mainly used to switch between the raw water output and purified water output modes. When switched to raw water output mode, the tap water discharged from the faucet passes directly through the faucet purifier without being filtered by the filter cartridge. When switched to purified water output mode, the tap water discharged from the faucet is filtered by the filter cartridge inside the faucet purifier before being discharged. This water path switching mechanism allows users to directly access raw and purified water without removing the faucet purifier, improving the user experience. However, most existing water path switching mechanisms are either knob-type or lever-type. Knob-type mechanisms typically have a protruding knob, and the water output mode is switched by rotating the knob. Lever-type mechanisms typically have a protruding lever, and the water output mode is switched by rotating the lever. The protruding knobs and levers make the faucet water purifiers larger in size, less aesthetically pleasing, and increase product packaging and transportation costs. Utility Model Content

[0004] This application provides a faucet water purifier to improve the technical problems of existing faucet water purifiers, such as large overall size, lack of simple appearance, and high product packaging and transportation costs.

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

[0006] A faucet water purifier includes a filtration unit, a water outlet component, 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 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 connected to the filter cartridge. The water outlet component is connected to the filter cartridge holder and has a water outlet channel. The raw water outlet and the purified water outlet are connected to the water outlet channel. The switching component is disposed between the water outlet component and the filter cartridge holder. The switching component includes a raw water valve core, a purified water valve core, and a connecting part. The connecting part connects the raw water valve core and the purified water valve core. The switching component can move back and forth between the raw water outlet position and the purified water outlet position relative to the filter cartridge seat. When the switching component is located at the raw water outlet position, it causes the raw water valve core to open the raw water outlet and the purified water valve core to close the purified water outlet. When the switching component is located at the purified water outlet position, it causes the raw water valve core to close the raw water outlet and the purified water valve core to open the purified water outlet.

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

[0008] The faucet water purifier also includes a mating component and an elastic component. The mating component is rotatably connected to the switching component. The elastic component is located between the connecting part and the filter element seat. The water outlet component has a locking protrusion and a clearance slide. The locking protrusion stops the mating component, keeping the switching component at the raw water outlet position. The mating component rotates relative to the switching component, disengaging from the locking protrusion and entering the clearance slide, so that the elastic component drives the switching component to switch from the raw water outlet position to the purified water outlet position.

[0009] The faucet water purifier also includes a drive component that is slidably connected to the water outlet component. When the drive component slides along the water outlet component, it can push the mating component to rotate relative to the switching component, while simultaneously causing the mating component to drive the switching component to translate.

[0010] The water outlet component is provided with a guide channel, the drive component is slidably disposed in the guide channel, the connecting part is provided with a guide post extending into the guide channel, the mating component is rotatably sleeved on the guide post, the locking protrusion and the clearance slide are alternately disposed in the guide channel along the circumference, the mating component is provided with radial protrusions distributed along the circumference, and when the mating component rotates, the radial protrusions stop with the locking protrusion or enter the clearance slide.

[0011] The driving member has a pushing protrusion and a limiting protrusion distributed circumferentially. The limiting protrusion cooperates with the avoidance slide to restrict the rotation of the driving member. The pushing protrusion has a guiding slope. The radial protrusion has a mating slope that forms an angle with the axial direction. When the driving member slides along the guide channel, it slides along the mating slope through the guiding slope, thereby driving the mating member to rotate in the first direction.

[0012] The locking protrusion is provided with a limiting groove. When the radial protrusion stops the locking protrusion, it is locked in the limiting groove to restrict the rotation of the mating part.

[0013] The elastic element is a spring, the filter element seat is provided with a first limiting groove, the connecting part is provided with a second limiting groove, and the two ends of the spring are respectively limited in the first limiting groove and the second limiting groove.

[0014] The water outlet component and the filter bottle are respectively connected to two opposite sides of the filter element seat. The water outlet component and the filter element seat form a water passage cavity. The raw water outlet and the purified water outlet are connected to the water outlet channel through the water passage cavity. The water outlet component is provided with a concave area facing the water passage cavity. The concave area is provided with an opening corresponding to the connecting part.

[0015] The faucet water purifier also includes a button, which is slidably disposed in the concave area and covers the opening. The button is used to apply a force to the connecting part to cause the switching element to translate.

[0016] The filter cartridge holder has two raw water outlets distributed on both sides of the purified water outlet. The raw water valve core is fitted with a first sealing ring for closing the raw water outlet, and the purified water valve core is fitted with a second sealing ring for closing the purified water outlet.

[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 is turned on. 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. Since both the raw water outlet and the purified water outlet are connected to the water outlet channel of the water outlet component, both raw water and purified water are discharged to the outside of the machine through the water outlet channel. The switching component is used to control the opening and closing states of the purified water outlet and the raw water outlet. When the raw water valve core opens the raw water outlet, the purified water valve core closes the purified water outlet, and vice versa, thereby switching the faucet water purifier between a state that can discharge purified water and a state that can discharge raw water. Specifically, when the switching element moves to the raw water outlet position, it opens the raw water valve core and simultaneously closes the purified water valve core. At this time, when the faucet discharges raw water, the raw water flows sequentially through the raw water inlet, filter chamber, raw water outlet, and outlet channel, thus putting the faucet water purifier in the raw water outlet state. When the switching element moves to the purified water outlet position, it closes the raw water valve core and simultaneously opens the purified water valve core. At this time, when the faucet discharges raw water, the raw water flows sequentially through the raw water inlet, filter element, purified water outlet, and outlet channel, thus putting the faucet water purifier in the purified water outlet state. Therefore, by controlling the switching element's translational movement relative to the filter element seat between the raw water outlet and purified water outlet positions, the raw water valve core and purified water valve core can be driven to perform corresponding translational movements, thereby achieving the switching between raw water outlet and purified water outlet states for the faucet water purifier, meeting the user's different needs for raw water and purified water. Furthermore, because the switching unit switches between the raw water outlet and the purified water outlet by translation, the translation of the switching unit can be controlled by a press-type structure. The press-type structure can be completely hidden inside the machine, so that there are no protruding features on the machine's appearance. This makes the machine more consistent and coordinated, smaller in size, and simpler in appearance, which helps to reduce product packaging and transportation costs.

[0019] 2. As a preferred embodiment, the mating component and the switching component are rotatably connected. By changing the rotational position of the mating component, the water output state of the faucet water purifier can be changed. Specifically, when the mating component rotates to the position abutting against the locking protrusion, the mating component holds the switching component at the raw water output position and compresses the elastic component with the connecting part, allowing the faucet water purifier to output raw water. When the mating component rotates to the position disengaging from the locking protrusion, it enters the clearance slide. At this time, the mating component can be translated towards the purified water output position under the drive of the elastic component, allowing the faucet water purifier to output purified water. Therefore, it is easy to implement and convenient to operate, and the switching of the switching component from the raw water output position to the purified water output position is automatically driven by the elastic component, resulting in a simple structure.

[0020] 3. As a preferred method, by setting a drive component that is slidably connected to the water outlet, the translational sliding of the drive component is converted into the rotational motion of the mating component. This allows the drive component to be configured for user-press operation. Simply pressing the drive component causes it to slide along the water outlet, which in turn pushes the mating component to rotate relative to the switching component. This allows the mating component to switch between a state of being stopped by the locking protrusion and a state of sliding engagement with the clearance slide. At the same time, the mating component drives the switching component to translate, thereby changing the opening and closing states of the raw water outlet and the purified water outlet.

[0021] 4. As a preferred embodiment, the water outlet component is provided with a guide channel, which can guide the sliding translation of the drive component. The locking protrusion and the avoidance slide are alternately arranged in the guide channel along the circumference, so that the mating component only needs to rotate continuously in a certain direction to alternate between the state of being stopped by the locking protrusion and the state of sliding engagement with the avoidance slide. It is easy to limit the rotation of the mating component to a certain direction, making the stroke of the structure simpler.

[0022] 5. As a preferred method, the limiting protrusion cooperates with the avoidance slide to restrict the rotation of the driving component, ensuring that the driving component can only slide along the guide channel, avoiding the driving component from rotating and interfering with the driving effect on the mating component; the driving component drives the mating component to rotate through the sliding cooperation between the guide slope and the mating slope, which has a simple structure, stable and reliable driving, and can limit the rotation of the mating component in a certain first direction, and the mating component will not rotate back and forth.

[0023] 6. As a preferred embodiment, the water outlet has a concave area that is recessed towards the water passage cavity, and the concave area has an opening corresponding to the connection part. The button is slidably disposed in the concave area, so that the button used to switch the water outlet state forms a hidden design and does not protrude from the water outlet.

[0059] 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.

[0060] Reference Figures 1 to 15 As shown, the faucet water purifier provided in this application includes a filtration unit, a water outlet 5, and a switching component 6. The filtration unit includes a filter cartridge seat 1, a filter bottle 2, and a filter cartridge 3. The filter bottle 2 is connected to the filter cartridge seat 1 to form a filtration chamber 4 that accommodates the filter cartridge 3. The filter cartridge seat 1 has a raw water inlet 11 and a raw water outlet 12 that are respectively connected to the filtration chamber 4, and a purified water outlet 13 that is connected to the filter cartridge 3. The water outlet 5 is connected to the filter cartridge seat 1 and has a water outlet channel 51. The raw water outlet 12 and the purified water outlet 13 are connected to the water outlet channel 51. The switching component 6 is disposed between the water outlet 5 and the filter cartridge seat 1. The switching component 6 includes a raw water valve core 61, a purified water valve core 62, and a connecting part 63. The connecting part 63 connects the raw water valve core 61 and the purified water valve core 62. The switching component 6 can move back and forth between the raw water outlet position and the purified water outlet position relative to the filter cartridge seat 1. Figures 1 to 4 The image shows the state of the switching component 6 when it is located at the raw water outlet position, as shown below. Figure 5and Figure 6 The diagram shows the state of the switching element 6 when it is located at the purified water outlet position. When the switching element 6 is located at the raw water outlet position, it causes the raw water valve core 61 to open the raw water outlet 12 and the purified water valve core 62 to close the purified water outlet 13; when the switching element 6 is located at the purified water outlet position, it causes the raw water valve core 61 to close the raw water outlet 12 and the purified water valve core 62 to open the purified water outlet 13.

[0061] 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, so an internal thread can be provided in the raw water inlet 11 to connect the raw water inlet 11 and the faucet. After the faucet water purifier is installed in the faucet, when the faucet is turned on, the tap water flows into the filter chamber 4 through the raw water inlet 11. 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. Since both the raw water outlet 12 and the purified water outlet 13 are connected to the water outlet channel 51 of the water outlet component 5, both the raw water and the purified water are discharged to the outside of the machine through the water outlet channel 51. The switching element 6 controls the opening and closing states of the purified water outlet 13 and the raw water outlet 12. When the raw water valve core 61 opens the raw water outlet 12, the purified water valve core 62 closes the purified water outlet 13; conversely, when the purified water valve core 62 opens the purified water outlet 13, the raw water valve core 61 closes the raw water outlet 12, thus switching the faucet water purifier between a state that can dispense purified water and a state that can dispense raw water. In a preferred embodiment, to facilitate the installation of the switching element 6, the water outlet component 5 can be detachably connected to the filter element seat 1, for example, by means of a threaded connection, improving the ease of installation and removal.

[0062] Specifically, when the switching element 6 moves to the raw water outlet position, the raw water valve core 61 opens the raw water outlet 12 while the purified water valve core 62 closes the purified water outlet 13. At this time, when the faucet discharges raw water, the raw water is discharged sequentially through the raw water inlet 11, the filter chamber 4, the raw water outlet 12, and the water outlet channel 51, so that the faucet water purifier is in the state of discharging raw water. When the switching element 6 moves to the purified water outlet position, the raw water valve core 61 closes the raw water outlet 12 while the purified water valve core 62 opens the purified water outlet 13. At this time, when the faucet discharges raw water, the raw water is discharged sequentially through the raw water inlet 11, the filter element 3, the purified water outlet 13, and the water outlet channel 51, so that the faucet water purifier is in the state of discharging purified water. Therefore, by simply controlling the switching element 6 to move relative to the filter cartridge seat 1 between the raw water outlet and the purified water outlet positions, the raw water valve core 61 and the purified water valve core 62 can be driven to perform corresponding translational movements. This allows the faucet water purifier to switch between raw water and purified water output states, meeting users' different needs for raw and purified water. Furthermore, because the switching element 6 switches between the raw water outlet and purified water outlet positions through translation, its movement can be controlled by a push-button structure. This push-button structure can be completely hidden inside the machine, resulting in a machine appearance without any protruding features, greater overall consistency and harmony, smaller size, and a simpler appearance, which helps reduce product packaging and transportation costs.

[0063] As a preferred embodiment of this application, such as Figure 2 , Figure 3 , Figure 6 , Figure 8 and Figure 9 As shown, the faucet water purifier also includes a mating part 7 and an elastic part 8. The mating part 7 is rotatably connected to the switching part 6. The elastic part 8 is located between the connecting part 63 and the filter element seat 1. The water outlet part 5 has a locking protrusion 52 and a clearance slide 53. The locking protrusion 52 stops the mating part 7, keeping the switching part 6 in the raw water outlet position. The mating part 7 rotates relative to the switching part 6, disengaging from the locking protrusion 52 and entering the clearance slide 53, causing the elastic part 8 to drive the switching part 6 to switch from the raw water outlet position to the purified water outlet position. Since the mating part 7 is rotatably connected to the switching part 6, the water outlet state of the faucet water purifier can be changed by changing the rotation position of the mating part 7. Specifically, for example... Figure 3 As shown, when the mating part 7 rotates to the position abutting against the locking protrusion 52, the mating part 7 maintains the switching part 6 in the raw water outlet position and causes the connecting part 63 to compress the elastic part 8. At this time, under the stopping action of the water outlet part 5 on the mating part 7, the mating part 7 stops and restricts the switching part 6 to the raw water outlet position, the raw water outlet 12 is opened, and the purified water outlet 13 is closed, allowing the faucet water purifier to dispense raw water; Figure 6As shown, when the mating part 7 rotates to the position where it disengages from the locking protrusion 52, it enters the clearance slide 53. At this time, the mating part 7 can be moved towards the purified water outlet position under the drive of the elastic element 8. At this time, the locking protrusion 52 cancels the stop restriction on the mating part 7, and the elastic element 8 is no longer pressed, thereby driving the switching part 6 to move. The raw water outlet 12 is closed, and the purified water outlet 13 is opened, so that the faucet water purifier can dispense purified water. Therefore, it is easy to implement and convenient to operate. Moreover, the control of the switching part 6 from the raw water outlet position to the purified water outlet position is automatically achieved by the elastic element 8, and the structure is simple.

[0064] As a preferred embodiment, such as Figure 3 , Figure 6 , Figure 13 and Figure 14 As shown, the faucet water purifier also includes a drive component 9 slidably connected to the water outlet 5. When the drive component 9 slides along the water outlet 5, it can push the mating component 7 to rotate relative to the switching component 6, while simultaneously causing the mating component 7 to drive the switching component 6 to translate. Those skilled in the art will understand that by setting the drive component 9 slidably connected to the water outlet 5, the translational sliding of the drive component 9 is converted into the rotational motion of the mating component 7. This allows the drive component 9 to be configured for user-press operation. Simply pressing the drive component 9 to make it slide along the water outlet 5 will push the mating component 7 to rotate relative to the switching component 6, thereby switching the mating component 7 between a state of stopping with the locking protrusion 52 and a state of sliding engagement with the avoidance slide 53. Simultaneously, the mating component 7 drives the switching component 6 to translate, thereby changing the opening and closing states of the raw water outlet 12 and the purified water outlet 13.

[0065] Furthermore, such as Figure 2 , Figure 3 as well as Figures 6 to 12As shown, the water outlet component 5 is provided with a guide channel 54, the driving component 9 is slidably disposed within the guide channel 54, the connecting portion 63 is provided with a guide post 631 extending into the guide channel 54, the mating component 7 is rotatably sleeved on the guide post 631, the locking protrusion 52 and the clearance slide 53 are alternately disposed circumferentially within the guide channel 54, and the mating component 7 is provided with radially distributed protrusions 71 circumferentially. When the mating component 7 rotates, the radial protrusions 71 stop with the locking protrusion 52 or enter the clearance slide 53. Those skilled in the art will understand that the water outlet component 5 is provided with a guide channel 54, the driving component 9 is slidably disposed within the guide channel 54, and the connecting portion 63 is provided with a guide post 631 extending into the guide channel 54. It can be seen that the guide channel 54 can not only guide the sliding translation of the driving component 9, but also guide the sliding translation of the mating component 7 and the switching component 6. The locking protrusion 52 and the clearance slide 53 are alternately arranged in the guide channel 54 along the circumference, so that the mating part 7 only needs to rotate continuously in a certain direction to alternate between the state of stopping with the locking protrusion 52 and the state of sliding engagement with the clearance slide 53. It is easy to restrict the rotation of the mating part 7 to a certain direction, making the stroke of the structure simpler. In addition, in the circumferential direction, the number of radial protrusions 71, the number of locking protrusions 52, and the number of clearance slides 53 can be kept consistent, so that when the switching part 6 is in the raw water switching position, all the locking protrusions 52 and radial protrusions 71 are in a one-to-one stop engagement; when the switching part 6 is in the purified water switching position, all the locking protrusions 52 and clearance slides 53 are in a one-to-one sliding engagement.

[0066] Regarding the method by which the driving member 9 drives the mating member 7 to rotate during sliding along the guide channel 54, in a preferred embodiment, such as... Figure 3 , Figure 6 as well as Figures 11 to 13As shown, the driving member 9 is provided with a pushing protrusion 91 and a limiting protrusion 92 distributed circumferentially. The limiting protrusion 92 cooperates with the avoidance slide 53 to restrict the rotation of the driving member 9. The pushing protrusion 91 is provided with a guiding slope 911. The radial protrusion 71 is provided with a mating slope 711 at an angle to the axial direction. When the driving member 9 slides along the guide channel 54, it slides along the mating slope 711 through the guiding slope 911, thereby driving the mating member 7 to rotate in the first direction. Those skilled in the art will understand that the limiting protrusion 92 cooperates with the avoidance slide 53 to restrict the rotation of the driving member 9, ensuring that the driving member 9 can only slide and translate along the guide channel 54, thus preventing the driving member 9 from rotating and interfering with the driving effect on the mating member 7. Since the rotational freedom of the driving member 9 is restricted, the rotational freedom of the mating member 7 is not restricted. Once the driving member 9 slides along the mating inclined surface 711 during translation, the mating member 7 can be driven to rotate in a first direction. The first direction is not limited and is determined by the inclination direction of the guide inclined surface 911 and the mating inclined surface 711. It can be set to counterclockwise rotation or clockwise rotation. The driving member 9 drives the mating member 7 to rotate through the sliding cooperation of the guide inclined surface 911 and the mating inclined surface 711. The structure is simple, the driving is stable and reliable, and the mating member 7 can be limited to rotating in a defined first direction, preventing the mating member 7 from reciprocating.

[0067] Therefore, through the above design, the driving component 9, the mating component 7, the guide channel 54 of the water outlet component 5, and the switching component 6 in this solution are combined to form a structure similar to a ballpoint pen press. Specifically, when the driving component 9 is pressed, the driving component 9 drives the mating component 7 and the switching component 6 to translate, while the mating component 7 rotates along the first direction. When the mating component 7 stops with the locking protrusion 52, the switching component 6 is maintained at the raw water outlet position, and the driving component 9 is also maintained in the pressed state. When the driving component 9 is pressed again, the driving component 9 drives the mating component 7 to rotate along the first direction again, and the mating component 7 switches from the locking protrusion 52 to the clearance slide 53. Then, the elastic component 8 drives the switching component 6 to translate to the clean water outlet position, and at the same time, the driving component 9 also resets to the unpressed state.

[0068] In a preferred embodiment, such as Figure 3 , Figure 6 and Figure 9As shown, the locking protrusion 52 is provided with a limiting groove 521. When the radial protrusion 71 stops with the locking protrusion 52, it is locked in the limiting groove 521 to restrict the rotation of the mating part 7, ensuring that the locking protrusion 52 can fix the position of the mating part 7, so that the mating part 7 stably limits the switching part 6 to the raw water outlet position. In this state, when the driving part 9 is pressed again, the driving part 9 will drive the mating part 7 and the switching part 6 to a certain translation, so that the radial protrusion 71 disengages from the limiting groove 521, thereby allowing the mating part 7 to rotate and switch to the clearance slide 53.

[0069] In a preferred embodiment, such as Figure 2 , Figure 5 , Figure 7 and Figure 15 As shown, the elastic element 8 is a spring, the filter element seat 1 is provided with a first limiting groove 14, and the connecting part 63 is provided with a second limiting groove 632. The two ends of the spring are respectively limited in the first limiting groove 14 and the second limiting groove 632, thereby limiting the spring in the radial direction and avoiding radial offset, twisting, bending and other phenomena of the spring, thereby ensuring that the switching element 6 can switch stably and reliably between the raw water outlet station and the purified water outlet station.

[0070] As a preferred embodiment of this application, such as Figure 1 , Figure 2 , Figure 4 and Figure 10 As shown, the water outlet 5 and the filter bottle 2 are respectively connected to two opposite sides of the filter cartridge seat 1. The water outlet 5 and the filter cartridge seat 1 form a water passage cavity 100. The raw water outlet 12 and the purified water outlet 13 are connected to the water outlet channel 51 through the water passage cavity 100. The water outlet 5 has a concave area 55 recessed towards the water passage cavity 100. The concave area 55 has an opening 56 corresponding to the connecting part 63. Specifically, the opening 56 in the concave area 55 corresponds to the connecting part 63, which facilitates the translation operation of the switching part 6. Taking the aforementioned embodiment as an example, the opening 56 can correspond to the guide channel 54. One end of the driving part 9 slides in the guide channel 54, and the other end can extend from the opening 56, so that the user can press the driving part 9 in the concave area 55.

[0071] Furthermore, such as Figure 2 and Figure 10As shown, the faucet water purifier also includes a button 200, which is slidably disposed within the concave area 55 and covers the opening 56. The button 200 is used to apply a force to the connecting part 63 to cause the switching member 6 to translate. By providing the button 200, it is convenient for the user to press the button 200 to drive the driving member 9 to slide. The button 200 is slidably disposed within the concave area 55, so that the button 200 used to switch the water outlet state has a hidden design and does not protrude from the water outlet member 5. Specifically, the button 200 can be threadedly connected to the driving member 9 for easy assembly and disassembly.

[0072] As a preferred embodiment of this application, such as Figure 2 and Figure 15 As shown, the filter cartridge seat 1 has two raw water outlets 12 distributed on both sides of the purified water outlet 13. The raw water valve core 61 is fitted with a first sealing ring 300 for closing the raw water outlet 12, and the purified water valve core 62 is fitted with a second sealing ring 400 for closing the purified water outlet 13. Those skilled in the art will understand that, generally, the flow rate of raw water is much greater than the flow rate of purified water. Therefore, by setting two raw water outlets 12 to discharge raw water simultaneously, the large flow rate of raw water can be met. When the switching element 6 is in the raw water outlet position, the second sealing ring 400 ensures that the purified water outlet 13 is sealed, preventing purified water leakage into the water passage chamber 100; when the switching element 6 is in the purified water outlet position, the first sealing ring 300 ensures that the raw water outlet 12 is sealed, preventing raw water leakage into the water passage chamber 100.
