[0021] 4. As a preferred embodiment of the present application, an elastic pressure member is arranged between the rotating member and the sealing member. The elastic pressure member applies elastic pressure to the sealing member so that the sealing member presses the flexible sealing gasket tightly, thereby ensuring that the sealing member and the flexible sealing gasket can be in stable and reliable contact with the flexible sealing gasket during both static and sliding processes, thereby ensuring an excellent sealing effect for the closed state of the raw water inlet or the clean water outlet.

The stoppers of the guide column at the two ends of the guide groove provide the operator with a tactile prompt that the rotating part has been rotated to the raw water outlet station or the clean water outlet station.

[0025] 8. As a preferred embodiment of the present application, the mounting portion is provided with a convex point protruding toward the water outlet cover, and a plurality of convex points are arranged at intervals along the rotation direction of the rotating part.

[0055] In the embodiment of the present application, a faucet water purifier is provided. For the convenience of explanation and understanding, the following contents provided in the present application are all explained on the basis of the illustrated product structure. Of course, those skilled in the art can understand that the above structure is only used as a specific example and schematic description, and cannot constitute a specific limitation on the technical solution provided in the present application.

[0056] Reference Figures 1 to 12 As shown, a tap water purifier provided by the present application includes a housing 1, a filter unit 2 and a water channel switching assembly, wherein the housing 1 has a raw water inlet 121, a raw water outlet 122 and a clean water outlet 123; the filter unit 2 is arranged in the housing 1, and the filter unit 2 has a clean water channel 21, wherein the clean water channel 21 connects the raw water inlet 121 and the clean water outlet 123, and a raw water channel 3 is formed between the filter unit 2 and the housing 1, wherein the raw water channel 3 connects the raw water inlet 121 and the clean water outlet 123. 1 is connected to the raw water outlet 122; the water channel switching assembly includes a rotating member 4 and a blocking member 5, the rotating member 4 is rotatably arranged on the shell 1, and the rotating member 4 can drive the blocking member 5 to switch between the raw water outlet position and the clean water outlet position during rotation. When the blocking member 5 is located at the raw water outlet position, the raw water outlet 122 is opened and the clean water outlet 123 is closed. When the blocking member 5 is located at the clean water outlet position, the clean water outlet 123 is opened and the raw water outlet 122 is closed. Figure 3 and Figure 5 The figure shows the state where the blocking member 5 is located at the raw water outlet position. At this time, the raw water outlet 122 is opened and the clean water outlet 123 is closed by the blocking member 5 .

[0057] In the faucet water purifier provided by the present application, the rotating part 4 can drive the blocking part 5 to switch between the raw water outlet position and the clean water outlet position during rotation. When the blocking part 5 rotates to the raw water outlet position, the raw water outlet 122 is opened and the clean water outlet 123 is closed. At this time, when the faucet discharges raw water to the outside, the raw water is discharged through the raw water inlet 121, the raw water channel 3, and the raw water outlet 122 in sequence, so that the faucet water purifier is in a raw water outlet state; when the blocking part 5 rotates to the clean water outlet position, the clean water outlet 123 is opened and the raw water outlet 122 is closed. At this time, when the faucet discharges raw water to the outside, the raw water is discharged through the raw water inlet 121, the raw water channel 3, and the raw water outlet 122 in sequence. After being converted into clean water through the raw water inlet 121 and the clean water channel 21, it is discharged through the clean water outlet 123, so that the faucet water purifier is in a clean water outlet state; therefore, it is only necessary to operate the rotating part 4 to rotate relative to the shell 1 to enable the blocking part 5 to control the faucet water purifier to switch between the raw water outlet state and the clean water outlet state, so as to meet the different usage scenarios of raw water and clean water by users, so that the overall parts of the water channel switching structure are relatively few, the space utilization rate is relatively high, and the water channel structure is simple, which is conducive to the miniaturization of the faucet water purifier and the saving of the production cost of the faucet water purifier, and also greatly improves the operational convenience of switching the water outlet state of the faucet water purifier.

[0058] During specific assembly, the raw water inlet 121 can be connected and installed with the faucet. When the faucet is draining, tap water enters the shell 1 from the raw water inlet 121, wherein a part of the tap water entering the shell 1 enters the raw water channel 3, and the other part enters the clean water channel 21 for filtration, and raw water or clean water is selected according to the position of the rotating part 4.

[0059] As a preferred embodiment of the present application, Figures 2 to 5As shown, the faucet water purifier also includes a flexible sealing gasket 6 installed on the shell 1, and the flexible sealing gasket 6 is provided with a raw water outlet 61 connected to the raw water outlet 122 and a clean water outlet 62 connected to the clean water outlet 123. The rotating member 4 presses the blocking member 5 against the flexible sealing gasket 6. When the blocking member 5 is located at the raw water outlet position, the raw water outlet 61 is opened and the clean water outlet 62 is closed. When the blocking member 5 is located at the clean water outlet position, the clean water outlet 62 is opened and the raw water outlet 61 is closed. Those skilled in the art can understand that, compared with directly pressing the plugging member 5 against the wall structure of the shell 1, the rotating member 4 presses the plugging member 5 against the flexible sealing pad 6, and the flexible sealing pad 6 constitutes the intermediate component of the plugging member 5 to open or close the raw water outlet 122 and the clean water outlet 123, and has good flexibility, so that the plugging member 5 and the flexible sealing pad 6 can be elastically pressed and sealed, and an elastic compression seal is also formed between the flexible sealing pad 6 and the shell 1, which effectively improves the sealing effect of the plugging member 5 when closing the raw water outlet 61 and the clean water outlet 62, and the sealing effect of the flexible sealing pad 6 on the raw water outlet 122 and the clean water outlet 123, and reduces the risk of raw water and clean water leakage. In a preferred embodiment, the flexible sealing pad 6 can be made of a silicone pad, which has many advantages such as being odorless, non-toxic, and having excellent flexibility.

[0060] As a preferred embodiment, Figure 5 and Figure 6 As shown, the housing 1 is provided with a limiting rib 124 protruding outward, the limiting rib 124 encloses a limiting space adapted to the flexible sealing pad 6, the raw water outlet 122 and the clean water outlet 123 are arranged in the limiting space, and the flexible sealing pad 6 is installed in the limiting space.

Those skilled in the art can understand that the limiting ribs 124 enclose a limiting space adapted to the flexible sealing pad 6, and the flexible sealing pad 6 is installed in the limiting space, and the sealing member 5 presses the flexible sealing pad 6 to achieve fixed limiting of the flexible sealing pad 6 on the shell 1, and prevents the rotation of the sealing member 5 from driving the flexible sealing pad 6 to move relative to the shell 1 and deviate from its position; the raw water guiding ribs 63 and the clean water guiding ribs 64 provided on the flexible sealing pad 6 are respectively inserted into the raw water outlet 122 and the clean water outlet 123, and not only the insertion cooperation of the raw water guiding ribs 63 and the raw water outlet 122 and the insertion cooperation of the clean water guiding ribs 64 and the clean water outlet 123 are utilized to achieve limiting, but also the raw water guiding ribs 63 are utilized to guide the raw water toward the raw water outlet 61, and the clean water guiding ribs 64 are utilized to guide the clean water toward the clean water outlet 62, thereby reducing the risk of raw water and clean water seeping. Specifically, because the flexible sealing gasket 6 is flexible and elastic, the structures of the raw water water guiding rib 63 and the clean water water guiding rib 64 can be slightly larger than the raw water outlet 122 and the clean water outlet 123 respectively, so that the raw water water guiding rib 63 and the clean water water guiding rib 64 are interference fit with the raw water outlet 122 and the clean water outlet 123 respectively, so as to further enhance the limiting effect and the sealing effect.

[0061] As a preferred embodiment, Figures 2 to 4 As shown, an elastic pressure member 7 is provided between the rotating member 4 and the blocking member 5, and the elastic pressure member 7 applies elastic pressure to the blocking member 5 so that the blocking member 5 presses the flexible sealing pad 6, ensuring that the blocking member 5 can stably and reliably contact the flexible sealing pad 6 during both the static and sliding processes, and ensuring an excellent sealing effect for the closed state of the raw water inlet 61 or the purified water outlet. Specifically, the elastic pressure member 7 can be a spring, so that the spring is in a compressed state between the rotating member 4 and the blocking member 5, so that when the rotating member 4 is limited, the reaction force of the spring can be used to elastically press the blocking member 5 against the flexible sealing pad 6.

Compared with the user operating the rotating member 4 to rotate, the setting of the operating rod 8 allows the user to rotate the rotating member 4 by toggling the operating rod 8, thereby extending the force arm of the force application, making the operation of rotating the rotating member 4 more convenient and labor-saving. Specifically, the operating rod 8 can be integrally connected with the rotating member 4 or form a detachable connection by means of a snap connection, a threaded connection, a screw connection, etc.

[0063] As a preferred implementation of the present application, Figures 1 to 3 as well as Fig. 9 and Fig.10 As shown, the faucet water purifier also includes a water outlet cover 9, which is detachably mounted on the shell 1, and the water outlet cover 9 and the shell 1 form a water outlet cavity 10, and the water outlet cover 9 is provided with a drain port 91, and the raw water outlet 122 and the purified water outlet 123 are respectively connected to the drain port 91 through the water outlet cavity 10, and the rotating member 4 and the blocking member 5 are confined in the water outlet cavity 10. Specifically, when the water outlet cover 9 is installed on the housing 1, the water outlet cover 9 and the housing 1 cooperate to form a water outlet chamber 10, and the raw water outlet 122 and the clean water outlet 123 are both open toward the water outlet chamber 10. The raw water outlet 122 and the clean water outlet 123 are connected to the drain port 91 through the water outlet chamber 10. On the one hand, the clean water and the raw water are discharged through the same water outlet, realizing integrated drainage, simplifying the waterway structure and the accessory structure. On the other hand, the raw water and the clean water can be cached and buffered in the water outlet chamber 10. When the amount of water in the water outlet chamber 10 reaches a certain level, it will be discharged through the drain port 91, which helps to improve the stability of water discharge and reduce the turbulent dispersion of water flow. When the raw water is discharged, the raw water enters the water outlet chamber 10 through the raw water outlet 122 and the raw water water outlet 61 in turn, and then is discharged through the drain port 91. Similarly, when the clean water is discharged, the clean water enters the water outlet chamber 10 through the clean water outlet 123 and the clean water water outlet 62 in turn, and then is discharged through the drain port 91. The rotating member 4 and the sealing member 5 are confined in the water outlet chamber 10 , so that the rotating member 4 can drive the sealing member 5 to rotate and switch positions in the water outlet chamber 10 , and the sealing member 5 can close the raw water outlet 61 or the purified water outlet 62 .

[0064] The present application does not specifically limit the detachable connection between the water outlet cover 9 and the housing 1.

Figure 4 and Figure 8 As shown, the rotating member 4 includes a rotating portion 41 and a mounting portion 42 connected to one side of the rotating portion 41, the shell 1 is provided with a rotating shaft 126 protruding from the water outlet chamber 10, and the water outlet cover 9 is provided with an avoidance hole 93, one end of the rotating portion 41 is rotatably mounted on the rotating shaft 126, and the other end passes through the water outlet chamber 10 through the avoidance hole 93, the blocking member 5 is installed on the mounting portion 42, and the water outlet cover 9 is pressed against the mounting portion 42. It is understood by those skilled in the art that by making one end of the rotating part 41 rotatably connected to the rotating shaft 126 and the other end passing through the avoidance hole 93, the rotating part 41 is exposed to the outside of the water outlet cover 9, so that the operator can operate the rotating part 41 to rotate on the outside of the water outlet cover 9. Therefore, in the embodiment in which the operating rod 8 is installed on the rotating member 4 and extends in a direction perpendicular to the rotating shaft 126 line of the rotating member 4, the operating rod 8 can be installed on the part of the rotating part 41 located outside the water outlet chamber 10, so that the operating rod 8 is exposed to the outside of the water outlet cover 9 for holding and applying force to rotate.

The water outlet cover 9 is pressed against the mounting portion 42 to limit the mounting portion 42 , and at the same time, the mounting portion 42 applies force to the elastic pressure member 7 and the blocking member 5 to press the blocking member 5 against the flexible sealing pad 6 .

[0066] Preferably, if Figure 4 , Figure 8 and Fig. 9 As shown, the mounting portion 42 is provided with a guide column 421 protruding toward the water outlet cover 9, and the water outlet cover 9 is provided with a guide groove 94 extending along the rotation direction of the rotating member 4, and the guide column 421 and the guide groove 94 are slidably matched to limit the raw water outlet position and the clean water outlet position to the two rotation limit positions of the rotating member 4. It can be understood by those skilled in the art that the raw water outlet position and the clean water outlet position are limited to the two rotation limit positions of the rotating member 4 by the sliding match between the guide column 421 and the guide groove 94, so as to achieve strict limitation of the rotation angle of the rotating member 4, and the two ends of the guide groove 94 stop the guide column 421, giving the operator a hand feeling prompt that the rotating member 4 has been rotated to the raw water outlet position or the clean water outlet position.

[0067] Preferably, if Figure 4 and Figure 8As shown, the mounting portion 42 is provided with a convex point 422 protruding toward the water outlet cover 9, and a plurality of the convex points 422 are arranged at intervals along the rotation direction of the rotating member 4, and the water outlet cover 9 is pressed against the convex points 422. It can be understood by those skilled in the art that when the water outlet cover 9 presses against the mounting portion 42, it also forms a friction barrier to the rotation of the mounting portion 42, and the greater the pressing force, the greater the friction barrier. Therefore, by pressing the water outlet cover 9 against the convex point 422, on the basis of ensuring that the water outlet cover 9 presses against the mounting portion 42, the contact area between the water outlet cover 9 and the mounting portion 42 is effectively reduced, thereby reducing the friction barrier from the water outlet cover 9 during the rotation of the rotating member 4, improving the smoothness of the rotation of the rotating member 4, and making the rotation operation more labor-saving.

It can be understood by those skilled in the art that by making the first end cover 11 and the second end cover 12 detachably connected, it is convenient to disassemble the two and expose the filter element 22 when replacing the filter element 22. Specifically, as Figure 3 , Fig.11 and Fig.12 As shown, the present application schematically illustrates an embodiment in which the first end cap 11 is provided with a screw-in slot 111, and the second end cap 12 is provided with a screw-in protrusion 128, and the first end cap 11 and the second end cap 12 are detachably connected by the screwing of the screw-in slot 111 and the screw-in protrusion 128. When the filter unit 2 is installed in place, the mounting head 23 and the sealing ring rib 127 are sealed and matched, so that the clean water channel 21 and the clean water outlet 123 are sealed and docked to prevent the clean water and the raw water from leaking. At this time, the gap formed between the outer side of the filter element 22 and the inner wall of the housing 1 constitutes the raw water channel 3. Preferably, a stop rib 129 can be provided on the inner side of the sealing ring rib 127, and the stop rib 129 abuts against the mounting head 23, so that the mounting head 23 maintains a certain distance from the end face of the housing 1 where the clean water outlet 123 is provided, thereby ensuring the cross-sectional area of ​​the flow channel and increasing the water flow rate.
