The sealing of the assembly position of the mounting flange 23212 and the cup body 211 is achieved through the cooperation between the top sealing part, the mounting flange 23212 and the bottom surface of the cup body 211; the sealing between the cup seat 212 and the cup body 211 is achieved through the cooperation between the bottom sealing part, the positioning sleeve 2113 and the cup seat 212; the sealing between the cup body 211 and the hydrogen-rich component 23, and between the cup body 211 and the cup seat 212 can be strengthened through the cooperation between the side sealing part, the inner wall of the mounting groove 2121 and the mounting flange 23212, and the sealing effect is good.

[0136] In other embodiments, the cup seal 214 can be embedded in a positioning groove on the inner wall of the mounting groove 2121 or the outer wall of the mounting flange 23212, and sealing can also be achieved.

[0137] In order to enable ionization, the electrode 233 needs to be energized. In order to more conveniently control the start and stop of the electrode 233 and ensure safe use, the electrode 233 can be energized after the hydrogen-rich component 23 and the cup component 21 in the hydrogen-rich module 20 are assembled, and the power can be automatically cut off after the hydrogen-rich component 23 and the cup component 21 are separated, so as to improve safety in use.

[0138] like Figure 5 As shown, a male terminal 235 is provided in the hydrogen-rich component 23, and a female terminal 236 is provided in the cup component 21. The male terminal 235 is connected to the electrode 233, and the female terminal 236 is used to connect the power supply. When the hydrogen-rich component 23 is installed at the bottom of the cup component 21, the female terminal 236 and the male terminal 235 are matched and contacted to achieve electrical connection. When the hydrogen-rich component 23 is removed from the cup component 21, the female terminal 236 and the male terminal 235 are separated and automatically disconnected.

[0139] Specifically, the hydrogen-rich component 23 also includes a hydrogen-rich shell 231 and an electrode shell 232. A reaction chamber 2320 is formed in the electrode shell 232. The electrode shell 232 is arranged at the top of the hydrogen-rich shell 231. The electrode shell 232 and the hydrogen-rich shell 231 form an installation cavity. One end of the male terminal 235 is arranged in the installation cavity and connected to the electrode 233, and the other end can extend out of the installation cavity to cooperate with the female terminal 236 in the cup assembly 21 to achieve a conductive connection.

[0140] Since the hydrogen-rich assembly 23 and the cup assembly 21 are assembled and disassembled by rotating, in order to prevent the male terminal 235 extending out of the hydrogen-rich shell 231 from interfering with the assembly and disassembly of the hydrogen-rich assembly 23 and the cup assembly 21, as shown in FIG. Figure 5 and Figure 6 As shown, the male terminal 235 is slidably arranged in the installation cavity along the height direction of the cup assembly 21, and the male terminal 235 includes a main body 2351, a coupling part 2353 and a sliding part 2352, the coupling part 2353 and the sliding part 2352 are both connected to the main body 2351, and a sliding hole 2312 is arranged on the hydrogen-rich shell 231, the sliding part 2352 passes through the sliding hole 2312 and can slide along the sliding hole 2312, the coupling part 2353 can be received in the installation space, and can extend out of the installation space to cooperate with the female terminal 236.

[0141] Before assembling the cup assembly 21 and the hydrogen-rich assembly 23, first slide the male terminal 235 downward by pushing the sliding portion 2352 so that the coupling portion 2353 can be retracted into the hydrogen-rich shell 231. After the hydrogen-rich assembly 23 and the cup assembly 21 are rotated and assembled, the male terminal 235 is slid upward by pushing the sliding portion 2352 so that the male terminal 235 extends out of the hydrogen-rich shell 231, so that the male terminal 235 can cooperate with the female terminal 236. When disassembling the hydrogen-rich assembly 23, the male terminal 235 is slid downward by pushing the sliding portion 2352 so that the male terminal 235 is retracted into the hydrogen-rich shell 231, and then the hydrogen-rich assembly 23 and the cup assembly 21 can be disassembled by rotation.

[0142] In order to improve the stability of the male terminal 235 in the hydrogen-rich shell 231, a slide groove 2313 is further provided in the hydrogen-rich shell 231, and the main body 2351 is slidably provided in the slide groove 2313, and the sliding hole 2312 is connected to the slide groove 2313. By providing the slide groove 2313, it is possible to provide a guide for the sliding of the main body 2351 in the hydrogen-rich shell 231, improve the position accuracy of the coupling part 2353, and ensure that the coupling part 2353 can be connected with the female terminal 236.

[0143] In order to improve the sliding stability of the male terminal 235, a guide groove 2311 is provided on the outer wall of the hydrogen-rich shell 231, the sliding hole 2312 is provided in the guide groove 2311, and the sliding part 2352 is slidably provided in the guide groove 2311. The guide groove 2311 can provide a guide for the sliding of the sliding part 2352, so that the sliding of the male terminal 235 is more stable.

[0144] In this embodiment, the male terminal 235 and the electrode 233 may be connected by a conductive member, which may be a wire. Figure 7 and Figure 8As shown, the electrode 233 is arranged in the electrode shell 232, and the electrode 233 includes a first lead-out end 2331 and a second lead-out end 2332. The first lead-out end 2331 and the second lead-out end 2332 extend out of the electrode shell 232. The first lead-out end 2331 and the second lead-out end 2332 are both connected to wires, and the wires are connected to the male terminal 235.

[0145] The electrode shell 232 includes an upper cover 2321 and a lower cover 2322, which are detachably connected, and a reaction chamber 2320 is formed between the upper cover 2321 and the lower cover 2322; the upper cover 2321 is provided with a central hole and a mounting flange 23212 arranged circumferentially around the central hole, and the first lead-out terminal 2331 and the second lead-out terminal 2332 both pass through the lower cover 2322 to be connected with the male terminal 235 in the mounting chamber. The electrode 233 is clamped and fixed between the upper cover 2321 and the lower cover 2322 and is directly opposite to the central hole. The upper cover 2321 and the lower cover 2322 are detachably connected to facilitate maintenance and replacement of the electrode 233, further increase the number of reusable parts in the hydrogen-rich component 23, and reduce maintenance costs. Optionally, the upper cover 2321 and the lower cover 2322 can be fixed by screws, which is convenient for disassembly and assembly.

[0146] Among them, the upper cover 2321 includes an annular plate 23211 and a mounting flange 23212 arranged around the center hole of the annular plate 23211, and the mounting flange 23212 is protruded toward the direction of the cup assembly 21; the lower cover 2322 is detachably arranged below the upper cover 2321, and the mounting flange 23212, the annular plate 23211 and the lower cover 2322 form a reaction chamber 2320, and the top end of the mounting flange 23212 forms an opening of the reaction chamber 2320 to communicate with the through hole of the cup assembly 21.

[0147] To prevent water leakage from the electrode shell 232, Fig. 9 and Fig.10 As shown, the electrode shell 232 also includes an electrode seal 2323, which is sleeved on the circumferential edge of the electrode 233. The electrode seal 2323 abuts against the upper cover 2321 and the lower cover 2322 respectively, thereby sealing the assembly gap of the electrode shell 232 to prevent the electrode shell 232 from leaking.

[0148] Specifically, Fig.10As shown, the electrode seal 2323 includes a sealing top plate 23232, a sealing bottom plate 23231 and a sealing side plate 23233. The sealing top plate 23232 and the sealing bottom plate 23231 are both annular plates 23211. The sealing side plate 23233 is arranged around the circumference of the sealing top plate 23232 and respectively connects the sealing top plate 23232 and the sealing bottom plate 23231. The sealing side plate 23233, the sealing top plate 23232 and the sealing bottom plate 23231 form a limiting groove. The circumferential edge of the electrode 233 is inserted into the limiting groove. The sealing top plate 23232 abuts against the upper cover 2321, and the sealing bottom plate 23231 abuts against the lower cover 2322 to achieve sealing.

[0149] In this embodiment, the top end of the sealing side plate 23233 extends out of the sealing top plate 23232, the bottom end of the mounting flange 23212 abuts against the sealing top plate 23232, and the top end of the sealing side plate 23233 is located on the inner side of the mounting flange 23212 and abuts against the mounting flange 23212, which can further improve the sealing effect.

[0150] In this embodiment, the electrode 233 includes a positive electrode sheet and a negative electrode sheet. To prevent the positive electrode sheet or the negative electrode sheet from warping and affecting the electrolysis effect, Fig.11 As shown, the upper cover 2321 further includes a pressing rib 23214, which is disposed in the reaction chamber 2320 and is used to abut against the front of the electrode 233 to press the electrode 233 toward the lower cover 2322, thereby preventing the middle of the electrode 233 from tilting. Specifically, the pressing rib 23214 is disposed in the center hole.

[0151] like Fig.11 As shown, three pressing ribs 23214 are provided, one end of the three pressing ribs 23214 is connected to one point, and the other end is connected to the inner wall of the reaction chamber 2320 to improve the anti-warping effect of the electrode 233.

[0152] In some embodiments, the hydrogen-rich component 23 further includes an outer cover 234 , which can be covered outside the hydrogen-rich shell 231 to improve the appearance of the hydrogen-rich component 23 .

[0153] In some embodiments, the outer cover 234 and the cup assembly 21 are fixed by adsorption, so as to improve the fixing effect of the hydrogen-rich assembly 23 and the cup assembly 21. Specifically, the outer cover 234 and the cup assembly 21 both include an adsorbent 213, and the adsorbent 213 can be adsorbed to each other to achieve fixation. Fig.12As shown, the adsorbent 213 in the cup assembly 21 is called a first magnetic adsorbent, which is disposed in the cup holder 212, and the adsorbent 213 of the hydrogen-rich assembly 23 is called a second magnetic adsorbent, which can be disposed in the outer cover 234. The adsorbents 213 in both the outer cover 234 and the cup assembly 21 can be magnets, or the adsorbent 213 of one of the hydrogen-rich assembly 23 and the cup assembly 21 is a magnet, and the adsorbent 213 of the other is an iron block.

[0154] In some embodiments, first magnetic elements are disposed on two opposite sides of the outer cover 234 , and the first magnetic elements on the two sides have opposite magnetic properties to form a fool-proof structure.

[0155] like Figure 1 and Figure 2 As shown, the hydrogen-rich module 20 further includes a joint 22, which is connected to the cup assembly 21, and a flow channel communicating with the interior of the cup assembly 21 is provided in the joint 22. The joint 22 is provided with a water inlet 222 and an exhaust port 221 communicating with the flow channel, the water inlet 222 is used to introduce water into the cup assembly 21, and the exhaust port 221 is used to discharge the gas in the cup assembly 21, so as to ensure that water can smoothly enter the cup assembly 21.

[0156] Optionally, the exhaust port 221 is higher than the water inlet 222 to facilitate smooth exhaust.

[0157] To further ensure the smoothness of exhaust from the hydrogen-rich module 20, Fig.13 and Fig.14 As shown, the flow channel in the joint 22 extends along the height direction of the cup body 211, and a vertically extending partition 223 is provided at the top of the flow channel to separate the top of the flow channel into two branches, the bottom end of the partition 223 is located below the water inlet 222, and a vent 2231 is provided at the top of the partition 223. This arrangement enables the water and gas in the flow channel to flow separately to avoid mutual interference, so that pure water can smoothly enter the hydrogen-rich module 20, and the gas can be smoothly discharged from the hydrogen-rich module 20.

[0158] In this embodiment, the water inlet 222 and the exhaust port 221 are located on the same side of the partition 223 . In other embodiments, the water inlet 222 and the exhaust port 221 may also be located on both sides of the partition 223 .

[0159] The cup assembly 21 is provided with a water outlet 2112, and the water outlet 2112 is used to provide hydrogen-rich water. In this embodiment, the cup assembly 21 is provided with a first water inlet 2111 and a water outlet 2112, and the first water inlet 2111 and the water outlet 2112 are respectively used to supply purified water or hydrogen-rich water to different parts to meet actual use requirements. Among them, the first water inlet 2111 is located above the water outlet 2112. The first water inlet 2111 is used to communicate with the water purification tank in the water purifier, and the water outlet 2112 is used to communicate with the water outlet structure in the water purifier.

[0160] In order to make the user's experience of drinking hydrogen-rich water more intuitive, the cup assembly 21 is made of transparent material. This arrangement allows the water in the cup assembly 21 and the bubbles generated during ionization to be visible from the outside of the cup assembly 21, thereby improving the user experience.

[0161] In this embodiment, the hydrogen-rich module 20 also includes a hydrogen-rich lamp assembly, which is arranged on the cup assembly 21. The light-emitting surface of the hydrogen-rich lamp assembly faces the inside of the cup assembly 21. The hydrogen-rich lamp assembly is used to illuminate the water in the cup assembly 21 so that the user can better observe the hydrogen production process.

[0162] Optionally, the hydrogen-rich lamp assembly may include at least one of a hydrogen-rich lighting lamp and a hydrogen-rich sterilization lamp, so as to sterilize water on the basis of lighting and ensure drinking water hygiene. The hydrogen-rich sterilization lamp may be an ultraviolet lamp.

[0163] like Fig.15 As shown, the water purifier also includes a housing 10, a raw water tank, a booster pump, a filter assembly, a box seat, a clean water tank 40 and the above-mentioned hydrogen-rich module 20. The booster pump, the box seat 70 and the clean water tank 40 are arranged in the housing 10, and the clean water tank 40 is arranged on the box seat 70. The booster pump connects the raw water tank and the filter assembly and provides power for the raw water in the raw water tank. The water inlet 222 of the hydrogen-rich module 20 is connected to the filter assembly. The raw water in the raw water tank is filtered by the filter assembly under the drive of the booster pump, and the filtered pure water flows to the hydrogen-rich module 20. The clean water tank 40 is connected to the first water outlet 2111 of the hydrogen-rich module 20. The pure water filtered by the filter assembly can enter the clean water tank 40 for storage after passing through the hydrogen-rich module 20, so that both the hydrogen-rich module 20 and the clean water tank 40 can store pure water, and the pure water reserve is increased to meet the needs of users. When the user needs water, the hydrogen-rich module 20 supplies hydrogen-rich water to the water outlet structure 30 . After the amount of pure water in the hydrogen-rich module 20 is reduced, pure water can be supplied to the hydrogen-rich module 20 from the clean water tank 40 .

[0164] In this embodiment, at least part of the hydrogen-rich module 20 is disposed outside the housing 10. Specifically, the front outer wall of the housing 10 is recessed into the housing 10 to form a receiving groove, and the hydrogen-rich component 23 and at least part of the cup component 21 are disposed in the receiving groove and exposed to the housing 10. Part of the hydrogen-rich module 20 is disposed on the front side of the housing 10 and is visible from the outside of the water purifier, which can improve the user experience. Since the cup component 21 is made of a transparent material, the user can directly see the water in the cup component 21 and the bubbles generated during the ionization process, so that the user has an intuitive feeling of drinking hydrogen-rich water and a better experience.

[0165] The hydrogen-rich component 23 is disposed outside the housing 10, and the hydrogen-rich component 23 is detachably connected to the cup component 21 to facilitate disassembly and maintenance of the hydrogen-rich component 23. The bottom surface of the hydrogen-rich component 23 is spaced from the housing 10 to form a certain distance. By setting the distance, space can be provided for disassembly and assembly of the hydrogen-rich component 23, which is convenient for operation.

[0166] like Fig.16 As shown, the water purifier also includes a water level detection box 50, the clean water tank 40 and the water level detection box 50 are arranged in the housing 10, the clean water tank 40 and the water level detection box 50 can be connected to form a communicating vessel, and the water level detection box 50 is used to detect the water level therein. The volume of the water level detection box 50 is smaller than the volume of the clean water tank 40, and the first water port 2111 on the hydrogen-rich module 20 is connected with the clean water tank 40 and the water level detection box 50 in sequence to supply clean water to the clean water tank 40 and the water level detection box 50. In order to make the water supply of the hydrogen-rich module 20 smoother, the height of the water inlet 222 of the hydrogen-rich module 20 connected to the pure water source is higher than the height of the first water port 2111.

[0167] In the present embodiment, a water level detection box 50 is added, and the principle of the communicating vessel is utilized to obtain the water level in the clean water tank 40 by detecting the water level in the water level detection box 50. There is no need to set a water level detection component in the clean water tank 40, and thus there is no need to add a sealing structure and a conductive structure in the clean water tank 40, which is beneficial to simplifying the internal structure of the clean water tank 40.

[0168] In addition, the clean water tank 40 has a larger volume, and the water level detection box 50 is only used for detecting the water level and has a smaller volume. The pure water provided by the hydrogen-rich module 20 first passes through the clean water tank 40 and then enters the water level detection box 50. The speed of change of the water level in the clean water tank 40 and the water level detection box 50 can be basically consistent, which is beneficial to ensure that the water level therein is the same as the water level in the clean water tank 40, thereby improving the accuracy of water level detection.

[0169] Specifically, the clean water tank 40 includes a second water port, and the water level detection box 50 includes a third water port. The second water port and the third water port can be connected, and the second water port and the third water port have the same height, so that the clean water tank 40 and the water level detection box 50 form a communicating vessel, so that the water level in the clean water tank 40 and the water level detection box 50 is detected by the water level detection box 50. The first water port 2111 of the hydrogen-rich module 20 can sequentially connect the second water port and the third water port, so that the hydrogen-rich module 20 supplies clean water to the clean water tank 40 and the water level detection box 50 in turn. Among them, the water in the hydrogen-rich module 20 can first pass through the second water port, and then pass through the third water port, so as to first supply water to the clean water tank 40, and then supply pure water to the water level detection box 50. When the water level in the hydrogen-rich module 20 drops, the water in the clean water tank 40 and the water level detection box 50 can also flow to the first water port 2111 to supply water to the hydrogen-rich module 20.

[0170] In order to allow the water in the clean water tank 40 and the water level detection box 50 to enter the hydrogen-rich module 20, the heights of the clean water tank 40 and the water level detection box 50 are higher than the first water inlet 2111, the second water inlet is arranged on the bottom surface of the clean water tank 40, and the third water inlet is arranged on the bottom surface of the water level detection box 50. This arrangement can drain the water in the clean water tank 40 and the water level detection box 50 to avoid residue.

[0171] It should be noted that, in order to enable the clean water tank 40 and the water level detection box 50 to form a communicating vessel to ensure that the water levels of the two are the same, the tops of the clean water tank 40 and the water level detection box 50 are both connected to the atmosphere. The clean water tank 40 includes a box body 41 and a box cover 42, and the inside of the clean water tank 40 can be connected to the outside atmosphere by using the assembly gap between the box body 41 and the box cover 42. A through hole is provided on the water level detection box 50, and the through hole is used to ensure that the water level detection box 50 is connected to the atmosphere.

[0172] The exhaust port 221 can be connected to the water level detection box 50 through a pipeline, so that the gas in the hydrogen-rich module 20 can be discharged into the atmosphere through the water level detection box 50, ensuring the smooth flow of pure water in and out of the hydrogen-rich module 20. By utilizing the characteristic that the water level detection box 50 is connected to the atmosphere, the exhaust function of the hydrogen-rich module 20 is integrated into the water level detection box 50, and there is no need to set an additional exhaust structure for the hydrogen-rich module 20, which is conducive to simplifying the internal structure of the water purifier to reduce costs.

[0173] In order to prevent the water in the water level detection box 50 from flowing back into the hydrogen rich module 20 through the exhaust port 221 of the hydrogen rich module 20, the height of the exhaust port 221 on the hydrogen rich module 20 is higher than the preset maximum water level of the water level detection box 50 to ensure that during the operation of the water purifier, the water level in the water level detection box 50 is lower than the exhaust port 221 to prevent the water in the water level detection box 50 from flowing back.

[0174] In this embodiment, Fig.17 and Fig.18 As shown, the water level detection box 50 includes a box body 51, a water level float 54 and a water level sensing component. A third water outlet is provided at the bottom of the box body 51, and the third water outlet is used to communicate with the hydrogen-rich module 20. A vertically extending float groove 511 is provided in the box body 51, and the water level float 54 is slidably provided in the float groove 511, so that the water level float 54 can slide along the float groove 511 as the water level in the box body 51 rises and falls. The water level sensing component is provided on the box body 51, and the water level sensing component can detect the position of the water level float 54, and is triggered when the water level float 54 is located at a preset low water level and a preset high water level of the box body 51, respectively.

[0175] When the water level float 54 is at the preset low water level, the water level float 54 triggers the water level sensor, and the water level sensor component sends information to the host of the water purification device. After receiving the signal, the host determines that the water level in the clean water tank 40 is at a low water level and needs to be supplemented with pure water. At this time, the host controls the boost pump to start, and the raw water passes through the filter component to prepare pure water. The pure water enters the clean water tank 40 after passing through the hydrogen-rich module 20 to supplement the clean water in the clean water tank 40. When replenishing pure water, the water level in the box body 51 increases, and the water level float 54 slides upward until it reaches the preset high water level, triggering the water level sensor component. The water level sensor component sends information to the host, and the host determines that the water level in the clean water tank 40 is at a high water level and needs to stop water intake. The host controls the boost pump to shut down and stop preparing raw water to prevent pure water from overflowing from the clean water tank 40.

[0176] In order to better detect the position of the water level float 54 in the box body 51, the water level sensing component includes a low water level sensing component 522 and a high water level sensing component 521, which are arranged vertically, and the low water level sensing component 522 corresponds to the preset low water level height in the box body 51, and the high water level sensing component 521 corresponds to the preset high water level height in the box body 51. Among them, the low water level sensing component 522 and the high water level sensing component 521 can both be proximity sensors, and correspondingly, the water level float 54 is a magnet, and the proximity sensor can sense the magnet within the sensing range.

[0177] Furthermore, the water level detection box 50 further includes an anti-overflow float 55 and an anti-overflow sensor 53. The anti-overflow float 55 is slidably disposed in the box body 51 in the vertical direction. The anti-overflow float 55 can trigger the anti-overflow sensor 53 when sliding to the overflow critical liquid level of the box body 51. The anti-overflow sensor 53 can send a signal to the host after being triggered. The host determines that there is an overflow risk in the clean water tank 40, stops supplying pure water to the clean water tank 40, or sends a warning signal to prompt the user to perform timely maintenance.

[0178] like Fig.19 and Fig. 20As shown, the water purification device also includes a box seat 70 and a connecting valve 80. The box seat 70 is arranged in the casing 10, the hydrogen-rich module 20 and the raw water tank are arranged outside the casing 10, the clean water tank 40 is detachably arranged in the box seat 70, the water level detection box 50 is arranged in the casing 10 and located on one side of the box seat 70, and the filter assembly is arranged in the casing 10 and located below the box seat 70.

[0179] The bottom of the box seat 70 is provided with an avoidance hole, and the clean water tank 40 can be detachably arranged in the box seat 70, so as to facilitate the removal of the clean water tank 40 for cleaning; the connecting valve 80 includes a first valve port, a second valve port and a third valve port, the first valve port is connected to the first water port 2111 on the hydrogen-rich module 20, and the third valve port is connected to the water level detection box 50; the clean water tank 40 includes a second water port, and the second water port can be connected to the second valve port through the avoidance hole. By setting the connecting valve 80, the hydrogen-rich module 20, the clean water tank 40 and the water level detection box 50 can be connected, which is conducive to simplifying the structure.

[0180] like Fig.21 As shown, the connecting valve 80 includes a valve body 81 and a valve core assembly, and the first valve port, the second valve port and the third valve port are all arranged on the valve body 81. The valve core assembly is arranged at the second valve port, and the valve core assembly can open the second valve port when the clean water tank 40 is installed in the tank seat 70, so that the second valve port is connected to the clean water tank 40, and can close the second valve port when the clean water tank 40 is removed from the tank seat 70, so as to prevent pure water from overflowing from the second valve port.

[0181] Specifically, the valve core assembly includes a valve body valve core 82 and a valve body elastic member 84. The valve body valve core 82 is slidably disposed in the second valve port, and the end of the valve body valve core 82 extending into the second valve port is the first blocking end; the valve body elastic member 84 elastically connects the valve body valve core 82 and the valve body 81. The elastic force of the valve body elastic member 84 can drive the valve body valve core 82 to move outward from the valve body 81, so that the first blocking end blocks the second valve port. When the clean water tank 40 is installed on the tank seat 70, as shown in FIG. Fig.21 As shown, the clean water tank 40 abuts against the valve body valve core 82, so that the valve body valve core 82 overcomes the elastic force of the valve body elastic member 84 and moves into the valve body 81, so that the first blocking end opens the second valve port. Fig. 22 As shown, the valve body valve core 82 moves outward from the valve body 81 under the driving action of the valve body elastic member 84, so that the first blocking end gradually approaches the second valve port, thereby blocking the second valve port to prevent pure water from overflowing.

[0182] Optionally, the valve body elastic member 84 may be a spring. Further, the first blocking end may be sleeved with a first sealing member 83, and the first sealing member 83 is elastic so as to better block the second valve port.

[0183] The valve body 81 includes a three-way pipe 812 and a valve seat 811. The two pipe ports of the three-way pipe 812 form a first valve port and a third valve port respectively, and the other pipe port is equipped with a valve seat 811, which forms a second valve port. A sealing ring is arranged between the valve seat 811 and the three-way pipe 812 to achieve sealing.

[0184] In order to enable the second valve port to communicate with the interior of the clean water tank 40, the clean water tank 40 includes a tank body 41 and a water tank valve core assembly 43. The tank body 41 is detachably connected to the tank seat 70, and the second water outlet is arranged on the bottom surface of the tank body 41; the water tank valve core assembly 43 includes a water tank valve core 431 and a water tank elastic member 432. The water tank valve core 431 is slidably arranged in the second water outlet, and the end of the water tank valve core 431 facing the interior of the tank body 41 is the second blocking end; the water tank elastic member 432 elastically connects the water tank valve core 431 and the tank body 41, and the elastic force of the water tank elastic member 432 can drive the water tank valve core 431 to slide out of the tank body 41, so that the second blocking end blocks the second water outlet. When the clean water tank 40 is installed on the tank seat 70, the water tank valve core 431 abuts against the valve body valve core 82, and the two interact with each other. The abutting force of the water tank valve core 431 on the valve body valve core 82 pushes the valve body valve core 82 to move into the valve body 81 to open the second valve port; the abutting force of the valve body valve core 82 on the water tank valve core 431 pushes the water tank valve core 431 to move into the box body 41 to open the second water port, thereby connecting the connecting valve 80 with the clean water tank 40. When the clean water tank 40 is removed from the box seat 70, the water tank valve core 431 moves to the outside of the box body 41 under the drive of the water tank elastic member 432, so that the second blocking end blocks the second water port to prevent the clean water tank 40 from leaking.

[0185] Optionally, the water tank elastic member 432 may be a spring. Further, the second blocking end may be sleeved with a second sealing member 433, and the second sealing member 433 is elastic so as to better block the second water outlet.

The limiting sleeve 411 can be inserted into the limiting groove and abut against the bottom surface of the limiting groove. The cooperation between the limiting sleeve 411 and the limiting groove facilitates the positioning of the clean water tank 40 and the connecting valve 80, thereby simplifying assembly.

[0187] Optionally, a fifth sealing member is provided between the limiting groove and the limiting sleeve 411 to improve the sealing effect at the joint between the clean water tank 40 and the connecting valve 80 .

[0188] In order to make the clean water tank 40 more stably placed in the box seat 70, the box seat 70 is provided with an annular flange 71 protruding into the box seat 70 around the avoidance hole, and the bottom of the box body 41 is provided with a support portion 412 protruding, the support portion 412 abuts against the inner bottom surface of the box seat 70, and the annular flange 71 abuts against the bottom surface of the box body 41. The box body 41 is supported by the support portion 412 and the annular flange 71 to make the position of the box body 41 more stable. The limiting sleeve 411 is inserted into the annular flange 71, which can facilitate the positioning of the clean water tank 40 and the box seat 70.

[0189] To prevent the gravity of the clean water tank 40 from being concentrated on the annular flange 71 and causing damage to the annular flange 71 , the height of the limiting sleeve 411 is smaller than the height of the support portion 412 protruding from the box body 41 , so that the support portion 412 can also play a role in supporting the box body 41 .

[0190] In order to facilitate the disassembly of the clean water tank 40, a handle is rotatably provided on the box cover 42 of the clean water tank 40. The handle can be rotated to a vertical position of the box cover 42, or rotated to be stacked on the top surface of the box cover 42 for storage. The clean water tank 40 can be taken in and out by pulling the handle, which is convenient for operation.

[0191] A handle is provided and is located in the middle of the box cover 42. In order to prevent the handle from protruding from the box cover 42 and occupying a large space when stored, an avoidance groove is provided on the top surface of the box cover 42. When the handle is folded on the box cover 42, the handle is completely arranged in the avoidance groove.

[0192] In some embodiments, two handles may be provided, and the two handles are rotatably disposed on opposite sides of the box cover 42 .

[0193] To facilitate the disassembly and assembly of the box cover 42 and the box body 41, lock buckles are rotatably connected on opposite sides of the box cover 42, and a locking part that is engaged with the lock buckle is provided at the top of the box body 41. The box cover 42 and the box body 41 can be fixed by engaging the lock buckle with the locking part.

[0194] The water purifier also includes a water outlet structure 30 and a heater.

The water outlet 2112 is connected to the normal temperature water inlet and the inlet of the heater respectively. The outlet of the heater is connected to the hot water inlet. The heater is used to heat water, so as to supply hot water to the user through the book outlet structure 30.

[0195] The first water inlet 2111 is connected to the clean water tank 40 and the water level detection box 50 through the connecting valve 80, and the water outlet 2112 is connected to the heater and the water outlet structure 30. When the clean water tank 40 is installed in the tank seat 70, the clean water tank 40 can provide clean water to the hydrogen enrichment module 20. When the clean water tank 40 is removed from the tank seat 70, clean water can be provided to the heater and the water outlet structure 30 through the hydrogen enrichment module 20.

[0196] When hot water needs to be provided to users, pure water at room temperature is generally passed into the heater to prepare hot water of the temperature required by the user. When the hot water required by the user is at a lower temperature, it can be provided to the user more quickly by heating it with the heater. However, when the hot water required by the user is at a higher temperature, such as above 85°C, it takes a long time to heat the room temperature water with the heater, which affects the user experience.

[0197] To solve the above problems, Fig.16 As shown, the water purifier also includes a thermos cup, the outlet of the heater is connected to the thermos cup, and the outlet of the thermos cup is connected to the inlet of the heater. By setting up the thermos cup, a portion of warm water can be pre-stored, that is, after the normal temperature water is heated to a certain temperature (for example, 40°C-60°C) by the heater, the warm water is stored in the thermos cup. When the user needs high-temperature hot water, the warm water in the thermos cup is passed into the heater for further heating to reduce the user's waiting time.

[0198] The water purifier also includes a sterilization mechanism, which can sterilize the purified water inside the purified water tank 40 when the purified water tank 40 is installed on the tank seat, so as to improve the user experience.
