[0039] This invention provides a water purifier; please refer to the following: Figures 1 to 14The system includes: a filtration mechanism 10, comprising a housing 11 and a first filter element 12 disposed within the housing 11; the housing 11 has a first flow channel 111, a second flow channel 112, and a purified water flow channel 113; the first flow channel 111 is connected to the first raw water end of the first filter element 12, and both the second flow channel 112 and the purified water flow channel 113 are connected to the first purified water end of the first filter element 12; and a water path conversion mechanism 20, connected to the housing 11, comprising an inlet 211 and an outlet 212. 2. The inlet 211 and outlet 212 are connected to the clean water channel 113. The water path switching mechanism 20 switches between the clean water state and the first cleaning state. When the water path switching mechanism 20 is in the clean water state, the inlet 211 is connected to the first channel 111 and the outlet 212 is open. When the water path switching mechanism 20 is in the first cleaning state, the inlet 211 is connected to the second channel 112, the first channel 111 is connected to the outlet 213 and the outlet 212 is closed.

[0040] The water purifier of the present invention includes a filtration mechanism 10 and a water path switching mechanism 20. The filtration mechanism 10 includes a housing 11 and a first filter element 12 disposed within the housing 11. The first filter element 12 is used to filter raw water to produce purified water that can be directly consumed by the user. When the water path switching mechanism 20 is in the water purification state, raw water is introduced from the inlet 211, flows sequentially through the first flow channel 111, the first filter element 12, and the purified water flow channel 113, and is finally discharged from the outlet 212 to complete the purification of the raw water. When the water path switching mechanism 20 is in the first cleaning state, raw water is introduced from the inlet 211, flows sequentially through the second flow channel 112, the first filter element 12, and the first flow channel 111, and is finally discharged from the drain outlet 213 to complete the rinsing of the first filter element 12. This water purifier switches between the water purification state and the first cleaning state through the water path switching mechanism 20, achieving water purification while allowing the filter element to be cleaned without removal. The water purifier of the present invention solves the problem that the filter element of the water purifier in the prior art is not easy to clean.

[0041] In this embodiment, as Figure 2 , Figure 10 and Figure 11As shown, the filtration mechanism 10 also includes a second filter element 13, which is disposed inside the housing 11. The second raw water end of the second filter element 13 is connected to the second flow channel 112, and the second clean water end of the second filter element 13 is connected to the clean water flow channel 113. The second clean water end of the second filter element 13 is connected to the first clean water end, so that the first clean water end is connected to the second flow channel 112 through the second filter element 13. The water circuit conversion mechanism 20 also has a second cleaning state. When the water circuit conversion mechanism 20 is in the clean water state, the inlet 211 is connected to the second flow channel 112. When the water circuit conversion mechanism 20 is in the second cleaning state, the inlet 211 is connected to the first flow channel 111, the second flow channel 112 is connected to the outlet 213, and the outlet 212 is closed. In specific implementation, when the water conversion mechanism 20 is in the water purification state, raw water is introduced into both the first flow channel 111 and the second flow channel 112. The raw water enters the first filter element 12 through the first flow channel 111 and the second filter element 13 through the second flow channel 112. The filtered purified water is then discharged through the purified water flow channel 113. When the water conversion mechanism 20 is in the first cleaning state, the water purifier rinses the first filter element 12. Specifically, raw water enters from the second flow channel 112 and enters the second filter element 13 from the second raw water end. After being filtered by the second filter element 13, it becomes purified water, which flows from the first purified water end of the first filter element 12. The water enters the first filter element 12 to achieve the purpose of rinsing the first filter element 12. The wastewater after rinsing the first filter element 12 enters the first flow channel 111 from the first raw water end of the first filter element 12 and is discharged. When the water circuit conversion mechanism 20 is in the second cleaning state, the water purifier rinses the second filter element 13. The raw water passes through the first flow channel 111 from the first raw water end of the first filter element 12 and passes through the first filter element 12. The filtered purified water directly enters the second filter element 13 from the second purified water end of the second filter element 13 to achieve the purpose of rinsing the second filter element 13. The wastewater after rinsing the second filter element 13 enters the second flow channel 112 from the second raw water end of the second filter element 13 and is discharged.

[0042] It should be noted that when the water circuit conversion mechanism 20 is in the first cleaning state and the second cleaning state, the water outlet 212 is closed. At this time, the water purifier does not discharge purified water.

[0043] Specifically, the first filter element 12 and the second filter element 13 can clean each other in both the first and second cleaning states. To achieve this cleaning function, the first flow channel 111 and the second flow channel 112 can be interchanged, serving as the inlet and outlet channels for each other. In the first cleaning state, raw water enters through the second flow channel 112, and the second filter element 13 provides filtered clean water to rinse the first filter element 12. After rinsing, the water is discharged from the second flow channel 112. In the second cleaning state, raw water enters through the second flow channel 112, and the first filter element 12 provides filtered clean water to rinse the second filter element 13. After rinsing, the water is discharged from the first flow channel 111.

[0044] In this embodiment, as Figure 3 As shown, the water channel conversion mechanism 20 includes: a mounting base assembly 21 connected to the housing 11; the mounting base assembly 21 has an inlet 211, an outlet 212, and a drain 213; the mounting base assembly 21 includes a first connecting channel 214, a second connecting channel 215, an inlet channel 216, and an outlet channel 217; the first end of the first connecting channel 214 is connected to the first flow channel 111; the first end of the second connecting channel 215 is connected to the second flow channel 112; the first end of the inlet channel 216 forms the inlet 211, and the clean water flow channel 113 is connected to... The water outlet 212 is connected to the water outlet through the water outlet channel 217; the movable part 22 has a first groove 221 and is movably disposed relative to the mounting base assembly 21. The movable part 22 has a first position. When the movable part 22 is in the first position, the water circuit conversion mechanism 20 is in the clean water state. The first groove 221 is connected to the second end of the water inlet channel 216, the second end of the first connecting channel 214, and the second end of the second connecting channel 215, so that the water inlet 211 is connected to the first flow channel 111 and the second flow channel 112.

[0045] Specifically, raw water enters the filtration mechanism 10 through the mounting base assembly 21 and the movable part 22 of the water path conversion mechanism 20 to achieve different functions of the water purifier. When the movable part 22 is in the first position, the water path conversion mechanism 20 is in the water purification state. Through the diversion and collection function of the first groove 221 of the movable part, the inlet 211 is connected to the first flow channel 111 and the second flow channel 112, allowing water from the inlet 211 to flow into the first flow channel 111 and the second flow channel 112. Raw water enters the first filter element 12 through the first flow channel 111 to produce purified water, and then enters the second filter element 13 through the second flow channel 112 to produce purified water. The purified water is discharged from the outlet 212. The first groove 221 of the water path conversion mechanism 20 enables the water purifier to achieve the function of the water purification mode.

[0046] Specifically, the inlet 211 and the outlet 212 are located on opposite sides of the mounting base assembly 21, and the drain outlet 213 is perpendicular to the inlet 211 and the outlet 212. This arrangement optimizes the layout of each flow channel.

[0047] In this embodiment, as Figure 8As shown, the mounting base assembly 21 includes a third connecting channel 218, the first end of which is connected to the drain outlet 213; the movable member 22 also has a second groove 222, and the movable member 22 has a second position. When the movable member 22 is in the second position, the water path conversion mechanism 20 is in a first cleaning state. The first groove 221 is connected to the second end of the water inlet channel 216 and the second end of the second connecting channel 215, so that the water inlet 211 is connected to the second flow channel 112; the second groove 222 is connected to the second end of the first connecting channel 214 and the second end of the third connecting channel 218, so that the first flow channel 111 is connected to the drain outlet 213.

[0048] Specifically, in the first cleaning state, raw water sequentially enters the second connecting channel 215 through the inlet 211, the inlet channel 216, and the first groove 221, thereby entering the second flow channel 112. The first connecting channel 214 is connected to the third connecting channel 218 through the second groove 222, so that the cleaned wastewater enters the first connecting channel 214 through the first flow channel 111, then passes through the third connecting channel 218, and is discharged from the drain outlet 213. The second groove 222 has the function of connecting the two connecting channels. By rotating the movable part 22, the second groove 222 can connect the first connecting channel 214 and the third connecting channel 218. By rotating the movable part 22, the first groove 221 can connect the inlet channel 216 and the second connecting channel 215, thereby changing the state of the water purifier to the first cleaning state.

[0049] In this embodiment, as Figure 7 As shown, the mounting base assembly 21 includes a fourth connecting channel 219, the first end of which is connected to the drain outlet 213; the movable member 22 has a third position, when the movable member 22 is in the third position, the water path conversion mechanism 20 is in the second cleaning state, the first groove 221 is connected to the second end of the first connecting channel 214 and the second end of the water inlet channel 216, so that the water inlet 211 is connected to the first flow channel 111; the second groove 222 is connected to the second end of the second connecting channel 215 and the second end of the fourth connecting channel 219, so that the second flow channel 112 is connected to the drain outlet 213.

[0050] Specifically, in the second cleaning state, raw water sequentially enters the first connecting channel 214 through the inlet 211, the inlet channel 216, and the first groove 221, thereby entering the first flow channel 111. The second connecting channel 215 is connected to the fourth connecting channel 219 through the second groove 222, so that the cleaned water enters the second connecting channel 215 through the second flow channel 112, then passes through the fourth connecting channel 219, and is discharged from the drain outlet 213. By rotating the movable part 22, the first groove 221 connects the inlet channel 216 and the second connecting channel 215; the second groove 222 connects the second connecting channel 215 and the fourth connecting channel 219, so that the cleaned water passes through the fourth connecting channel 219 and is discharged from the drain outlet 213. The fourth connecting channel 219 connects the second flow channel 112 and the drain outlet 213, realizing the second cleaning state of the water purifier.

[0051] In this embodiment, as Figure 5 As shown, the mounting bracket assembly 21 includes a mounting bracket body 23 and a fixing member 24 disposed on the mounting bracket body 23, with the movable member 22 pressed onto the fixing member 24; the mounting bracket body 23 has a first channel segment 231, a second channel segment 232, a third channel segment 233, a fourth channel segment 234, and a fifth channel segment 235; the fixing member 24 is provided with a first through hole 241, a second through hole 242, a third through hole 243, a fourth through hole 244, and a fifth through hole 245; the first through hole 241 and the first through hole 245 are connected to the first through hole 242. Section 231 is connected to form a first connecting channel 214; a second through hole 242 is connected to the second channel section 232 to form a second connecting channel 215; a third through hole 243 is connected to the third channel section 233 to form a third connecting channel 218; a fourth through hole 244 is connected to the fourth channel section 234 to form a fourth connecting channel 219; and a fifth through hole 245 is connected to the fifth channel section 235 to form a water inlet channel 216. Both the fixing member 24 and the moving member 22 are made of ceramic. Specifically, by setting the fixing member 24 and making both the fixing member 24 and the moving member 22 ceramic, the seal between the fixing member 24 and the moving member 22 is ensured, thereby ensuring the sealing state between the first groove, the second groove, and each connecting channel (i.e., the water inlet channel, the first connecting channel, the second connecting channel, the third connecting channel, and the fourth connecting channel, etc.).

[0052] Specifically, the first through hole 241, the second through hole 242, the third through hole 243, the fourth through hole 244, and the fifth through hole 245 are located on the fixing member 24, corresponding to the first channel section 231, the second channel section 232, the third channel section 233, the fourth channel section 234, and the fifth channel section 235 of the mounting base body 23, respectively, and cooperating with the first groove 221 and the second groove 222 to switch the water circuit conversion mechanism 20 to the clean water state, the first cleaning state, and the second cleaning state.

[0053] Specifically, the fifth through hole 245 is located at the center of the movable member 22, and the first through hole 241 and the second through hole 242 are located on opposite sides of the center of the movable member 22. The angle between the lines connecting the two through holes and the center of the movable member 22 is less than 180 degrees. In the clean water state, the first through hole 241, the second through hole 242, and the fifth through hole 245 are connected to the first groove 221. The fifth through hole 245 is located at the center of the first groove 221, and the first through hole 241 and the second through hole 242 are located at both ends. The first through hole 241, the second through hole 242, the third through hole 243, and the fourth through hole 244 are arranged around the fifth through hole 245. The third through hole 243 and the fourth through hole 244 are both located between the first through hole 241 and the second through hole 242, so that the first through hole 241 and the third through hole 243 are both connected to the second groove 222, or the second through hole 242 and the fourth through hole 244 are both connected to the second groove 222.

[0054] In this embodiment, as Figure 5 As shown, the mounting bracket assembly 21 also includes a seal 25 disposed between the mounting bracket body 23 and the fixing member 24 to seal the space between the mounting bracket body 23 and the fixing member 24.

[0055] In this embodiment, as Figure 9 As shown, the water channel conversion mechanism 20 also includes a mounting cover 26, which covers the mounting base assembly 21, and a movable member 22 is disposed between the mounting cover 26 and the mounting base assembly 21. In a specific implementation, the accommodating space between the mounting cover 26 and the mounting base body 23 protects the movable member 22 and the fixed member 24.

The movable component 22 switches between a first position, a third position, and a fourth position by rotating.

[0058] Specifically, the drive component 30 is mounted on the mounting cover 26, and the drive shaft of the drive component 30 passes through the mounting cover 26 and is connected to the movable component 22.

[0059] Specifically, the drive unit 30 is located on top of the mounting cover 26.

[0060] Specifically, the driving component 30 is a motor, and correspondingly, the drive shaft of the motor is coaxially connected to the movable component 22; or, the driving component 30 is a motor and a transmission structure, with the motor connected to the movable component 22 through the transmission structure.

[0061] In this embodiment, as Figure 2 As shown, the filtration mechanism 10 also includes a pipeline component 14, which is disposed inside the housing 11 and passes through the second filter element 13, forming a clean water flow channel 113.

This arrangement makes the water purifier structure compact.

[0063] In this embodiment, as Figure 2 As shown, the housing 11 has a barrel-shaped structure. The first filter element 12 and the second filter element 13 are arranged sequentially in the vertical direction. The channel between the side of the first filter element 12 and the housing 11, the channel between the side of the second filter element 13 and the housing 11, and the channel between the partition 15 and the housing 11 together form the first flow channel 111. This arrangement makes the water purifier compact, highly integrated, and small in size.

[0064] Specifically, the first filter element 12 is located below the second filter element 13, and the first filter element 12 and the second filter element 13 are arranged vertically at intervals to form a gap; the pipe component 14 passes through the second filter element 13, the first end of the pipe component 14 extends into the gap, and the second end of the pipe component 14 extends to the side of the partition 15 away from the second filter element 13; the first flow channel 111 is arranged around the filter element (including the first filter element 12 and the second filter element 13) and extends directly to the bottom of the first filter element 12, that is, the first raw water end of the first filter element 12, to provide raw water to the first filter element 12; the second flow channel 112 is arranged parallel to the first flow channel 111 at the inlet of the housing 11 and extends to the upper part of the second filter element 13, that is, the second raw water end of the second filter element 13, to provide raw water to the second filter element 13; the purified water flow channel 113 passes through the gap between the first filter element 12 and the second filter element 13 and extends to the outside to provide purified water to the user.

[0065] In practical implementation, the water purifier also includes a water purifier control board 40, which is communicatively connected to the drive component 30. The water purifier control board 40 sends control commands to the drive component 30 to cause the movable component to rotate to different positions, thereby switching the water purifier to different working modes. These different working modes include a first working mode, a second working mode, and a third working mode. In the first working mode, the movable component is in the first position, and the water path switching mechanism 20 is in the water purification state. In the second working mode, the movable component is in the second position, and the water path switching mechanism 20 is in the first cleaning state. In the third working mode, the movable component is in the third position, and the water path switching mechanism 20 is in the second cleaning state.

[0066] This application uses only two filter cartridges to achieve water purification, and also allows the two filter cartridges to flush each other. The water purifier has a compact structure, high integration, small size, and can achieve mutual flushing of filter cartridges, thus extending the life of the filter cartridges.

[0067] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0068] The water purifier of the present invention includes a filtration mechanism 10 and a water path switching mechanism 20. The filtration mechanism 10 includes a housing 11 and a first filter element 12 disposed within the housing 11. The first filter element 12 is used to filter raw water to produce purified water that can be directly consumed by the user. When the water path switching mechanism 20 is in the water purification state, raw water is introduced from the inlet 211, flows sequentially through the first flow channel 111, the first filter element 12, and the purified water flow channel 113, and is finally discharged from the outlet 212 to complete the purification of the raw water. When the water path switching mechanism 20 is in the first cleaning state, raw water is introduced from the inlet 211, flows sequentially through the second flow channel 112, the first filter element 12, and the first flow channel 111, and is finally discharged from the drain outlet 213 to complete the rinsing of the first filter element 12. This water purifier switches between the water purification state and the first cleaning state through the water path switching mechanism 20, achieving water purification while allowing the filter element to be cleaned without removal. The water purifier of the present invention solves the problem that the filter element of the water purifier in the prior art is not easy to clean.
