The top sealing portion can be pressed by the mounting flange 23212 against the bottom surface of the cup body 211. The side sealing portion can be clamped between the mounting flange 23212 and the positioning sleeve 2113. The bottom sealing portion can be clamped between the positioning sleeve 2113 and the cup base 212. Through the cooperation of the top sealing portion with the mounting flange 23212 and the bottom surface of the cup body 211, sealing at the assembly position of the mounting flange 23212 and the cup body 211 is achieved. Through the cooperation of the bottom sealing portion with the positioning sleeve 2113 and the cup base 212, sealing between the cup base 212 and the cup body 211 is achieved. Through the cooperation of the side sealing portion with the inner wall of the installation groove 2121 and the mounting flange 23212, the sealing between the cup body 211 and the hydrogen-rich component 23 and between the cup body 211 and the cup base 212 can be strengthened, and the sealing effect is good.

[0137] In other embodiments, the cup seal 214 can be embedded in the positioning groove on the inner wall of the installation groove 2121 or the outer wall of the mounting flange 23212, and sealing can also be achieved.

[0138] In order to be able to perform ionization, it is necessary to energize the electrode 233. For more convenient control of the start and stop of the electrode 233 and use safety, after the hydrogen-rich component 23 and the cup assembly 21 in the hydrogen-rich module 20 are assembled, the electrode 233 can be energized, and power can be automatically cut off after the hydrogen-rich component 23 is separated from the cup assembly 21 to improve use safety.

[0139] As Figure 5 shown, a male terminal 235 is provided inside the hydrogen-rich component 23, and a female terminal 236 is provided inside the cup assembly 21. The male terminal 235 is connected to the electrode 233, and the female terminal 236 is used to connect to the power supply. When the hydrogen-rich component 23 is installed at the bottom of the cup assembly 21, the female terminal 236 and the male terminal 235 are in contact and cooperate to achieve electrical connection. When the hydrogen-rich component 23 is removed from the cup assembly 21, the female terminal 236 and the male terminal 235 are separated, and the connection is automatically disconnected.

[0140] Specifically, the hydrogen-rich component 23 further includes a hydrogen-rich housing 231 and an electrode housing 232. A reaction chamber 2320 is formed inside the electrode housing 232. The electrode housing 232 is disposed at the top of the hydrogen-rich housing 231. The electrode housing 232 and the hydrogen-rich housing 231 enclose an installation cavity. One end of the male terminal 235 is disposed inside the installation cavity and communicates with the electrode 233, and the other end can extend outside the installation cavity to cooperate with the female terminal 236 in the cup component 21 to achieve electrical connection.

[0141] Since the hydrogen-rich component 23 and the cup component 21 are disassembled and assembled by rotation, to prevent the male terminal 235 extending outside the hydrogen-rich housing 231 from interfering with the disassembly and assembly of the hydrogen-rich component 23 and the cup component 21, as Figure 5 and Figure 6 shown, the male terminal 235 is slidably disposed in the installation cavity along the height direction of the cup component 21. The male terminal 235 includes a main body 2351, a coupling portion 2353, and a sliding portion 2352. The coupling portion 2353 and the sliding portion 2352 are both connected to the main body 2351. A sliding hole 2312 is provided on the hydrogen-rich housing 231. The sliding portion 2352 passes through the sliding hole 2312 and can slide along the sliding hole 2312. The coupling portion 2353 can be received in the installation space and can extend outside the installation space to cooperate with the female terminal 236.

[0142] Before assembling the cup component 21 and the hydrogen-rich component 23, first slide the male terminal 235 downward by pushing the sliding portion 2352, so that the coupling portion 2353 can retract into the hydrogen-rich housing 231. After rotatably assembling the hydrogen-rich component 23 and the cup component 21, slide the male terminal 235 upward by pushing the sliding portion 2352, so that the male terminal 235 extends outside the hydrogen-rich housing 231, facilitating the male terminal 235 to cooperate with the female terminal 236. When disassembling the hydrogen-rich component 23, slide the male terminal 235 downward by pushing the sliding portion 2352, so that the male terminal 235 retracts into the hydrogen-rich housing 231, and then the hydrogen-rich component 23 and the cup component 21 can be disassembled by rotation.

[0143] To improve the stability of the male terminal 235 inside the hydrogen-rich housing 231, a sliding groove 2313 is further provided inside the hydrogen-rich housing 231. The main body 2351 is slidably disposed in the sliding groove 2313, and the sliding hole 2312 communicates with the sliding groove 2313. By providing the sliding groove 2313, it can provide guidance for the sliding of the main body 2351 inside the hydrogen-rich housing 231, improve the position accuracy of the coupling portion 2353, and ensure that the coupling portion 2353 can be docked with the female terminal 236.

[0144] To improve the stability of the sliding of the male terminal 235, a guiding groove 2311 is provided on the outer wall of the hydrogen-rich housing 231. The sliding hole 2312 is disposed in the guiding groove 2311, and the sliding portion 2352 is slidably disposed in the guiding groove 2311. By providing the guiding groove 2311, it can provide guidance for the sliding of the sliding portion 2352, thereby making the sliding of the male terminal 235 more stable.

[0145] In this embodiment, the male terminal 235 and the electrode 233 can be connected by a conductive member, and the conductive member can be a wire. As Figure 7 and Figure 8 shown, the electrode 233 is disposed within the electrode housing 232. 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 housing 232. Wires are connected to both the first lead-out end 2331 and the second lead-out end 2332, and the wires are connected to the male terminal 235.

[0146] The electrode housing 232 includes an upper cover 2321 and a lower cover 2322. The upper cover 2321 and the lower cover 2322 are detachably connected. A reaction chamber 2320 is defined between the upper cover 2321 and the lower cover 2322. The upper cover 2321 is provided with a central hole and an installation flange 23212 circumferentially arranged around the central hole. Both the first lead-out end 2331 and the second lead-out end 2332 pass through the lower cover 2322 to be connected to the male terminal 235 within the installation cavity. The electrode 233 is clamped and fixed between the upper cover 2321 and the lower cover 2322 and is aligned with the central hole. The upper cover 2321 and the lower cover 2322 are detachably connected to facilitate the maintenance and replacement of the electrode 233, further increasing the number of reusable parts in the hydrogen-rich component 23 and reducing the maintenance cost. Optionally, the upper cover 2321 and the lower cover 2322 can be fixed by screws, which is convenient for disassembly and assembly.

[0147] Among them, the upper cover 2321 includes an annular plate 23211 and an installation flange 23212 arranged around the central hole of the annular plate 23211. The installation flange 23212 protrudes towards the cup component 21. The lower cover 2322 is detachably disposed below the upper cover 2321. The installation flange 23212, the annular plate 23211, and the lower cover 2322 define the reaction chamber 2320. The top end of the installation flange 23212 forms the opening of the reaction chamber 2320 to communicate with the through hole of the cup component 21.

[0148] To prevent the electrode housing 232 from leaking water, as Figure 9 and Figure 10 shown, the electrode housing 232 further includes an electrode seal 2323. The electrode seal 2323 is sleeved on the circumferential edge of the electrode 233. The electrode seal 2323 abuts against both the upper cover 2321 and the lower cover 2322 respectively, thereby sealing the assembly gap of the electrode housing 232 and preventing the electrode housing 232 from leaking water.

[0149] Specifically, as Figure 10As shown, the electrode seal 2323 includes a sealing top plate 23232, a sealing bottom plate 23231, and a sealing side plate 23233. Both the sealing top plate 23232 and the sealing bottom plate 23231 are annular plates 23211. The sealing side plate 23233 is disposed around the circumference of the sealing top plate 23232 and is respectively connected to 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 enclose 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.

[0150] In this embodiment, the top end of the sealing side plate 23233 extends outside the sealing top plate 23232. The bottom end of the mounting flange 23212 abuts against the sealing top plate 23232. The top end of the sealing side plate 23233 is located inside the mounting flange 23212 and abuts against the mounting flange 23212, which can further improve the sealing effect.

[0151] In this embodiment, the electrode 233 includes a positive electrode plate and a negative electrode plate. To prevent the positive electrode plate or the negative electrode plate from warping and affecting the electrolysis effect, as Figure 11 shown, the upper cover 2321 further includes a pressing rib 23214. The pressing rib 23214 is disposed in the reaction chamber 2320 and is used to abut against the front surface of the electrode 233 to press the electrode 233 against the lower cover 2322, thereby preventing the middle of the electrode 233 from warping. Specifically, the pressing rib 23214 is disposed in the central hole.

[0152] As Figure 11 shown, there are three pressing ribs 23214. One ends of the three pressing ribs 23214 are connected to one point, and the other ends are connected to the inner wall of the reaction chamber 2320 to improve the anti-warping effect on the electrode 233.

[0153] In some embodiments, the hydrogen-rich component 23 further includes an outer cover 234. The outer cover 234 can cover the hydrogen-rich shell 231 to improve the appearance of the hydrogen-rich component 23.

[0154] In some embodiments, the outer cover 234 and the cup component 21 are adsorbed and fixed to improve the fixing effect between the hydrogen-rich component 23 and the cup component 21. Specifically, both the outer cover 234 and the cup component 21 include adsorbing members 213. The adsorbing members 213 can adsorb each other to achieve fixation. As Figure 12As shown, the adsorbing member 213 within the cup assembly 21 is referred to as the first magnetic member, which is disposed within the cup base 212. The adsorbing member 213 of the hydrogen-rich assembly 23 is referred to as the second magnetic member, and the second magnetic member can be disposed within the outer cover 234. The adsorbing member 213 in both the outer cover 234 and the cup assembly 21 can be a magnet, or the adsorbing member 213 of one of the hydrogen-rich assembly 23 and the cup assembly 21 is a magnet, and the adsorbing member 213 of the other is an iron block.

[0155] In some embodiments, first magnetic members are disposed on opposite sides within the outer cover 234, and the magnetic properties of the first magnetic members on both sides are opposite to form an anti-misassembly structure.

[0156] As Figure 1 and Figure 2 shown, the hydrogen-rich module 20 further includes a connector 22. The connector 22 is connected to the cup assembly 21, and a flow channel communicating with the interior of the cup assembly 21 is disposed within the connector 22. An inlet 222 and an exhaust port 221 communicating with the flow channel are provided on the connector 22. The 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 to ensure that water can smoothly enter the cup assembly 21.

[0157] Optionally, the height of the exhaust port 221 is higher than that of the inlet 222 for smooth exhaust.

[0158] To further ensure the smoothness of the exhaust of the hydrogen-rich module 20, as Figure 13 and Figure 14 shown, the flow channel within the connector 22 extends along the height direction of the cup body 211. A vertically extending partition 223 is provided at the top of the flow channel to divide the top of the flow channel into two branches. The bottom end of the partition 223 is located below the inlet 222, and a vent hole 2231 is provided at the top end of the partition 223. This arrangement enables the water and gas in the flow channel to flow separately, avoiding 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.

[0159] In this embodiment, the inlet 222 and the exhaust port 221 are located on the same side of the partition 223. In other embodiments, the inlet 222 and the exhaust port 221 can also be located on opposite sides of the partition 223 respectively.

[0160] The cup assembly 21 is provided with a water outlet 2112, and the water outlet 2112 is used to supply hydrogen-rich water. In this embodiment, the cup assembly 21 is provided with a first water passing port 2111 and a water outlet 2112. The first water passing port 2111 and the water outlet 2112 are respectively used to supply purified water or hydrogen-rich water to different parts to meet the actual use requirements. Among them, the first water passing port 2111 is located above the water outlet 2112. The first water passing port 2111 is used to communicate with the purified water tank in the water purifier, and the water outlet 2112 is used to communicate with the water outlet structure in the water purifier.

[0161] To make the user's experience of drinking hydrogen-rich water more intuitive, the cup assembly 21 is made of a transparent material. This setting makes the water and the bubbles generated during ionization inside the cup assembly 21 visible from the outside of the cup assembly 21, so as to improve the user experience.

[0162] In this embodiment, the hydrogen-rich module 20 further includes a hydrogen-rich lamp assembly. The hydrogen-rich lamp assembly is arranged on the cup assembly 21, and 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.

[0163] Optionally, the hydrogen-rich lamp assembly may include at least one of a hydrogen-rich illumination lamp and a hydrogen-rich sterilization lamp, so as to achieve water sterilization on the basis of illumination and ensure drinking water hygiene. The hydrogen-rich sterilization lamp can be an ultraviolet lamp.

[0164] As Figure 15 As shown, the water purifier further includes a machine shell 10, a raw water tank, a booster pump, a filtration component, a tank seat, a purified water tank 40 and the above-mentioned hydrogen-rich module 20. The booster pump, the tank seat 70 and the purified water tank 40 are arranged inside the machine shell 10. The purified water tank 40 is arranged on the tank seat 70. The booster pump is connected to the raw water tank and the filtration component and provides power for the raw water in the raw water tank. The water inlet 222 of the hydrogen-rich module 20 is communicated with the filtration component. The raw water in the raw water tank is filtered by the filtration component under the drive of the booster pump, and the filtered pure water flows to the hydrogen-rich module 20. The purified water tank 40 is communicated with the first water passing port 2111 of the hydrogen-rich module 20. The purified water filtered by the filtration component can enter the purified water tank 40 for storage after passing through the hydrogen-rich module 20, so that both the hydrogen-rich module 20 and the purified water tank 40 can store purified water, increasing the purified water reserve to meet the user's use. When the user needs to use water, the hydrogen-rich module 20 supplies hydrogen-rich water to the water outlet structure 30. After the amount of purified water in the hydrogen-rich module 20 decreases, the purified water tank 40 can supply purified water to the hydrogen-rich module 20.

[0165] In this embodiment, at least a part of the hydrogen-rich module 20 is disposed outside the machine housing 10. Specifically, a receiving groove is formed by the front outer wall of the machine housing 10 recessing into the machine housing 10. The hydrogen-rich component 23 and at least a part of the cup component 21 are disposed in the receiving groove and are exposed outside the machine housing 10. A part of the hydrogen-rich module 20 is disposed on the front side of the machine 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, giving the user an intuitive feeling of drinking hydrogen-rich water and a better experience.

[0166] The hydrogen-rich component 23 is disposed outside the machine housing 10. The hydrogen-rich component 23 and the cup component 21 are detachably connected to facilitate disassembly and maintenance of the hydrogen-rich component 23. Among them, the bottom surface of the hydrogen-rich component 23 is spaced from the machine housing 10 to form a certain distance. By setting this distance, space can be provided for the disassembly and assembly of the hydrogen-rich component 23, facilitating operation.

[0167] As Figure 16 shown, the water purifier further includes a water level detection box 50. The water purification tank 40 and the water level detection box 50 are disposed in the machine housing 10. The water purification tank 40 and the water level detection box 50 can communicate to form a communicating vessel. 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 water purification tank 40. The first water inlet 2111 on the hydrogen-rich module 20 is sequentially communicated with the water purification tank 40 and the water level detection box 50 to supply purified water to the water purification tank 40 and the water level detection box 50. To make the water supply of the hydrogen-rich module 20 smoother, the height of the water inlet 222 where the hydrogen-rich module 20 is connected to the pure water source is higher than the height of the first water inlet 2111.

[0168] In this embodiment, the water level detection box 50 is added, and based on the principle of the communicating vessel, the water level in the water purification tank 40 is obtained by detecting the water level in the water level detection box 50, without the need to set a water level detection component in the water purification tank 40. Therefore, there is no need to add a sealing structure and a conductive structure in the water purification tank 40, which is beneficial to simplifying the internal structure of the water purification tank 40.

[0169] In addition, the volume of the water purification tank 40 is relatively large, and the water level detection box 50 is only used for detecting the water level and has a relatively small volume. The purified water provided by the hydrogen-rich module 20 first passes through the water purification tank 40 and then enters the water level detection box 50, which can make the change speed of the water levels in the water purification tank 40 and the water level detection box 50 basically the same, facilitating ensuring that the water level therein is the same as the water level in the water purification tank 40, thereby improving the accuracy of water level detection.

[0170] Specifically, the clean water tank 40 includes a second water passing port, and the water level detection box 50 includes a third water passing port. The second water passing port and the third water passing port can be connected, and the heights of the second water passing port and the third water passing port are the same, so that the clean water tank 40 and the water level detection box 50 form a communicating vessel, and thus the water levels in the clean water tank 40 and the water level detection box 50 can be detected through the water level detection box 50. The first water passing port 2111 of the hydrogen-rich module 20 can be sequentially connected to the second water passing port and the third water passing 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 sequence. Among them, the water in the hydrogen-rich module 20 can first pass through the second water passing port and then through the third water passing port, so as to supply water to the clean water tank 40 first 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 passing port 2111 to supply water to the hydrogen-rich module 20.

[0171] To enable the water in both the clean water tank 40 and the water level detection box 50 to enter the hydrogen-rich module 20, the heights of both the clean water tank 40 and the water level detection box 50 are higher than the first water passing port 2111. The second water passing port is arranged at the bottom surface of the clean water tank 40, and the third water passing port is arranged at the bottom surface of the water level detection box 50. This setting can drain the water in the clean water tank 40 and the water level detection box 50 completely and avoid residue.

[0172] It should be noted here that to enable the clean water tank 40 and the water level detection box 50 to form a communicating vessel to ensure that their water levels are the same, the tops of both the clean water tank 40 and the water level detection box 50 are in communication with the atmosphere. Among them, the clean water tank 40 includes a box body 41 and a box cover 42, and the internal part of the clean water tank 40 can be in communication with the external atmosphere by using the assembly gap between the box body 41 and the box cover 42. The water level detection box 50 is provided with a through hole, and this through hole is used to ensure the communication between the water level detection box 50 and the atmosphere.

[0173] The exhaust port 221 can be connected to the water level detection box 50 through a pipeline, so as to discharge the gas in the hydrogen-rich module 20 into the atmosphere through the water level detection box 50 to ensure the smooth inflow and outflow of pure water in the hydrogen-rich module 20. By using the characteristic that the water level detection box 50 is in communication with the atmosphere, the exhaust function of the hydrogen-rich module 20 is integrated in the water level detection box 50, and there is no need to additionally set an exhaust structure for the hydrogen-rich module 20, which is beneficial to simplifying the internal structure of the water purifier and reducing costs.

[0174] 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, so as 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.

[0175] In this embodiment, asFigure 17 and Figure 18 As shown in Figure 18 , 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 inlet is provided at the bottom end of the box body 51, and the third water inlet 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 arranged 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 arranged on the box body 51, and the water level sensing component can detect the position of the water level float 54 and is triggered respectively when the water level float 54 is at the preset low water level and the preset high water level of the box body 51.

[0176] When the water level float 54 is at the preset low water level, the water level float 54 triggers the water level sensing element, and the water level sensing component sends a message to the main unit of the water purification device. After obtaining the signal, the main unit judges that the water level in the water purification tank 40 is at the low water level and pure water needs to be replenished. At this time, the main unit controls the booster pump to start, the raw water is prepared into pure water through the filtration component, and the pure water enters the water purification tank 40 after passing through the hydrogen-rich module 20 to replenish pure water into the water purification 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 and triggers the water level sensing component. The water level sensing component sends a message to the main unit, and the main unit judges that the water level in the water purification tank 40 is at the high water level and the water inlet needs to be stopped. The main unit controls the booster pump to close and stops preparing the raw water to prevent the pure water in the water purification tank 40 from overflowing.

[0177] 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 element 522 and a high water level sensing element 521. The low water level sensing element 522 and the high water level sensing element 521 are arranged vertically. The low water level sensing element 522 corresponds to the preset low water level height in the box body 51, and the high water level sensing element 521 corresponds to the preset high water level height in the box body 51. Among them, both the low water level sensing element 522 and the high water level sensing element 521 can be proximity sensors. Correspondingly, the water level float 54 is a magnet, and the proximity sensor can sense the magnet within the sensing range.

[0178] Furthermore, the water level detection box 50 further includes an anti-overflow float 55 and an anti-overflow sensing element 53. The anti-overflow float 55 is slidably arranged in the box body 51 in the vertical direction, and the anti-overflow float 55 can trigger the anti-overflow sensing element 53 when sliding to the overflow critical liquid level of the box body 51. The anti-overflow sensing element 53 can send a signal to the main unit after being triggered. The main unit judges that there is a risk of overflow in the water purification tank 40, stops supplying pure water into the water purification tank 40, or issues a warning signal to prompt the user to perform maintenance in time.

[0179] As Figure 19 and Figure 20As shown, the water purification device further includes a box base 70 and a connection valve 80. The box base 70 is arranged inside the housing 10, the hydrogen-rich module 20 and the raw water tank are arranged outside the housing 10, the purified water tank 40 is detachably arranged inside the box base 70, the water level detection box 50 is arranged inside the housing 10 and on one side of the box base 70, and the filtering assembly is arranged inside the housing 10 and below the box base 70.

[0180] An avoidance hole is provided at the bottom of the box base 70, and the purified water tank 40 is detachably arranged inside the box base 70 to facilitate the removal of the purified water tank 40 for cleaning. The connection valve 80 includes a first valve port, a second valve port and a third valve port. The first valve port communicates with the first water passing port 2111 on the hydrogen-rich module 20, and the third valve port communicates with the water level detection box 50. The purified water tank 40 includes a second water passing port, and the second water passing port can communicate with the second valve port through the avoidance hole. By providing the connection valve 80, the connection of the hydrogen-rich module 20, the purified water tank 40 and the water level detection box 50 can be realized, which is beneficial to simplifying the structure.

[0181] As Figure 21 shown, the connection valve 80 includes a valve body 81 and a valve core assembly. 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. The valve core assembly can open the second valve port when the purified water tank 40 is installed in the box base 70 to make the second valve port communicate with the purified water tank 40, and can close the second valve port when the purified water tank 40 is removed from the box base 70 to prevent pure water from overflowing from the second valve port.

[0182] 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 arranged inside the second valve port, and one 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 is elastically connected to the valve body valve core 82 and the valve body 81, and the elastic force of the valve body elastic member 84 can drive the valve body valve core 82 to move out of the valve body 81 so that the first blocking end blocks the second valve port. When the purified water tank 40 is installed on the box base 70, as Figure 21 shown, the purified water tank 40 abuts against the valve body valve core 82, causing the valve body valve core 82 to move into the valve body 81 against the elastic force of the valve body elastic member 84, thereby opening the second valve port with the first blocking end. When the purified water tank 40 is removed from the box base 70, as Figure 22 shown, the valve body valve core 82 moves out of the valve body 81 under the driving action of the valve body elastic member 84, causing the first blocking end to gradually approach the second valve port, thereby blocking the second valve port and preventing pure water from overflowing.

[0183] Optionally, the valve body elastic member 84 can be a spring. Further, a first sealing member 83 can be sleeved on the first blocking end. The first sealing member 83 has elasticity to better block the second valve port.

[0184] The valve body 81 includes a three-way pipe 812 and a valve seat 811. Two pipe orifices of the three-way pipe 812 respectively form a first valve orifice and a third valve orifice, and a valve seat 811 is installed at the other pipe orifice, and the valve seat 811 forms a second valve orifice. A sealing ring is arranged between the valve seat 811 and the three-way pipe 812 to achieve sealing.

[0185] To enable the second valve orifice to communicate with the inside of the water purification tank 40, the water purification 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 a second water passing orifice is arranged at 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 passing orifice, and one end of the water tank valve core 431 facing the inside of the tank body 41 is a second blocking end; the water tank elastic member 432 is elastically connected to 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 passing orifice. When the water purification 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 act on 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 orifice; 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 tank body 41 to open the second water passing orifice, so as to connect the connecting valve 80 and the water purification tank 40. When the water purification tank 40 is removed from the tank seat 70, the water tank valve core 431 moves outward of the tank body 41 under the drive of the water tank elastic member 432, so that the second blocking end blocks the second water passing orifice to prevent the water purification tank 40 from leaking.

[0186] Optionally, the water tank elastic member 432 can be a spring. Further, a second sealing member 433 can be sleeved on the second blocking end, and the second sealing member 433 has elasticity to better block the second water passing orifice.

[0187] To improve the stability of the movement of the water tank valve core 431, a limiting sleeve 411 is protrudingly arranged around the second water passing orifice on the bottom surface of the tank body 41. The water tank valve core 431 is located in the limiting sleeve 411, and a limiting groove is arranged on the connecting valve 80. The limiting sleeve 411 can be inserted into the limiting groove and abut against the bottom surface of the limiting groove. Through the cooperation of the limiting sleeve 411 and the limiting groove, it is convenient to position the water purification tank 40 and the connecting valve 80, thus simplifying the assembly.

[0188] Optionally, a fifth sealing member is arranged between the limiting groove and the limiting sleeve 411 to improve the sealing effect at the joint of the water purification tank 40 and the connecting valve 80.

[0189] To make the water purification tank 40 more stable when placed in the tank base 70, the tank base 70 is provided with an annular flange 71 protruding inward around the avoidance hole. The bottom of the box body 41 is provided with a support portion 412, and the support portion 412 abuts against the inner bottom surface of the tank base 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 together 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 water purification tank 40 and the tank base 70.

[0190] To prevent the gravity of the water purification tank 40 from concentrating at the annular flange 71 and causing damage to the annular flange 71, the height of the limiting sleeve 411 is less 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.

[0191] To facilitate the disassembly of the water purification tank 40, a handle is rotatably provided on the lid 42 of the water purification tank 40. The handle can be rotated to a position perpendicular to the lid 42 or rotated and stacked on the top surface of the lid 42 for storage. The water purification tank 40 is taken and placed by pulling the handle, and the operation is convenient.

[0192] There is one handle, which is located in the middle of the lid 42. To prevent the handle from protruding from the lid 42 and occupying a large space when stored, an avoidance groove is provided on the top surface of the lid 42. When the handle is stacked on the lid 42, the handle is completely arranged in the avoidance groove.

[0193] In some embodiments, there can be two handles, and the two handles are rotatably provided on opposite sides of the lid 42.

[0194] To facilitate the disassembly and assembly of the lid 42 and the box body 41, locking buckles are rotatably connected to opposite sides of the lid 42, and a locking portion that is engaged with the locking buckles is provided at the top end of the box body 41. The lid 42 and the box body 41 can be fixed by the engagement of the locking buckles and the locking portion.

[0195] The water purifier further includes a water outlet structure 30 and a heater. The water outlet structure 30 includes a normal temperature water inlet, a hot water inlet, and a water supply outlet, and can provide normal temperature water and hot water to users. A second water passing port is provided on the water purification tank 40. The first water passing port 2111 is communicated with the second water passing port. The water outlet 2112 is respectively communicated with the normal temperature water inlet and the inlet of the heater. The outlet of the heater is communicated with the hot water inlet. The heater is used to heat water, so as to supply hot water to users through the water outlet structure 30.

[0196] The first water passing port 2111 is communicated with the water purification tank 40 and the water level detection box 50 through a connection valve 80. The water outlet 2112 is communicated with the heater and the water outlet structure 30. When the water purification tank 40 is installed in the tank base 70, the water purification tank 40 can provide purified water to the hydrogen-rich module 20. When the water purification tank 40 is removed from the tank base 70, the hydrogen-rich module 20 can provide purified water to the heater and the water outlet structure 30.

[0197] When hot water needs to be provided to the user, generally, normal-temperature pure water is passed into the heater, and hot water at the temperature required by the user is prepared through the heater. When the temperature of the hot water required by the user is relatively low, it can be provided to the user relatively quickly through heating by the heater. However, when the temperature of the hot water required by the user is relatively high, for example, above 85°C, it takes a long time to heat normal-temperature water through the heater, affecting the user experience.

[0198] To solve the above problems, as Figure 16 shown, the water purifier further includes a heat-preservation cup 60. The outlet of the heater is connected to the heat-preservation cup 60, and the outlet of the heat-preservation cup 60 is connected to the inlet of the heater. By providing the heat-preservation cup 60, a part of warm water can be pre-stored. That is, after normal-temperature water is heated to a certain temperature (for example, 40°C - 60°C) through the heater, the warm water is stored in the heat-preservation cup 60. When the user needs high-temperature hot water, the warm water in the heat-preservation cup 60 is passed into the heater for further heating to reduce the waiting time of the user.

[0199] The water purifier further includes a sterilization mechanism. The sterilization mechanism can sterilize the purified water inside the water purification tank 40 when the water purification tank 40 is installed on the tank seat, so as to improve the user experience.

[0200] In this embodiment, as Figure 23 shown, the sterilization mechanism includes a sterilization lamp assembly 91 and a lamp socket assembly 92. An installation hole is provided at the bottom of the water purification tank 40, and at least the light-emitting end of the sterilization lamp assembly 91 is hermetically arranged in the installation hole. A conductive contact pin 913 is provided on the bottom surface of the sterilization lamp assembly 91; the lamp socket assembly 92 is arranged on the tank seat 70 and is used to connect to the power supply. The lamp socket assembly 92 includes a lamp socket 921 and a conductive female seat 922 arranged on the lamp socket 921. The conductive female seat 922 is connected to the power supply, and the conductive female seat 922 can contact the conductive contact pin 913 to supply power to the sterilization lamp assembly 91. By supplying power to the sterilization lamp assembly 91 through the contact between the lamp socket assembly 92 and the sterilization lamp assembly 91 via the conductive contact pin 913 and the conductive female seat 922, no conductive structure needs to be provided inside the water purification tank 40, which is beneficial to simplifying the sealing structure of the water purification tank 40 and improving the use safety.

[0201] The sterilization lamp assembly 91 includes a circuit protection shell 911, a circuit board 912, and a sterilization lamp 914. A lamp hole is provided on the top surface of the circuit protection shell 911, and a contact pin hole is provided on the bottom surface of the circuit protection shell 911; the circuit board 912 is arranged inside the circuit protection shell 911. The sterilization lamp 914 and the conductive contact pin 913 are both arranged on the circuit board 912 and are electrically connected to the circuit board 912. The sterilization lamp 914 extends into the installation hole through the lamp hole, and the conductive contact pin 913 passes through the contact pin hole to extend outside the circuit protection shell 911.

[0202] To prevent the water in the water purification tank 40 from contacting the germicidal lamp assembly 91 through the mounting hole, a sealing ring is provided between the bottom surface of the water purification tank 40 and the circuit protection housing 911 to seal the assembly gap.

[0203] To make the water purifier more intelligent, the water purifier further includes a detection trigger and a detection sensor. The detection trigger is provided on the bottom surface of the circuit protection housing 911, and the detection sensor is provided on the lamp holder 921. When the water purification tank 40 is installed in the tank seat 70, the detection trigger can trigger the detection sensor, so as to judge whether the water purification tank 40 is installed in the tank seat 70. When the water purification tank 40 is not installed in the tank seat 70, the main body of the water purifier sends a prompt message to remind the user to install the water purification tank 40.

[0204] Optionally, the detection trigger can be a detection probe, and the detection sensor is a detection female seat, and the detection female seat is connected in series in the detection circuit. When the detection probe contacts the detection female seat, the detection circuit is connected; when the detection probe is separated from the detection female seat, the detection circuit is disconnected. Whether the water purification tank 40 is installed in the tank seat 70 can be detected by the on-off state of the detection circuit.

[0205] In some embodiments, the detection sensor can be a proximity switch or a micro switch. When the water purification tank 40 is installed in the tank seat 70, the detection trigger is within the detection range of the proximity switch or presses the reed of the micro switch, so that the detection signal of the proximity switch or the micro switch changes, so as to judge whether the water purification tank 40 is installed in the tank seat 70.

[0206] In some embodiments, as Figure 24 shown, the sterilization mechanism includes a lamp cover 93 and a germicidal lamp assembly 91. The bottom surface of the water purification tank 40 is provided with a mounting hole, and the lamp cover 93 is hermetically arranged in the mounting hole; the germicidal lamp assembly 91 is fixedly arranged on the tank seat 70 and connected to the power supply. When the water purification tank 40 is loaded onto the tank seat 70, the light-emitting end of the germicidal lamp assembly 91 extends into the lamp cover 93.

[0207] Optionally, the lamp cover includes a cover body 931, a lamp cover 932 and a lamp cover seal 933. The cover body 931 is arranged in the water purification tank 40 and partially located in the mounting hole; the lamp cover seal 933 is arranged between the mounting hole and the cover body 931 to block the gap therebetween; the lamp cover 932 is sleeved outside the cover body 931 and is detachably connected to the water purification tank 40. The lamp cover 932 is used to press the cover body 931 against the water purification tank 40 and squeeze the lamp cover seal 933 to improve the sealing effect. Among them, the lamp cover 932 is threadedly connected to the mounting hole.

[0208] The machine body further includes an operation panel, which is arranged at the top of the front side wall of the machine shell 10 and above the hydrogen-rich module 20, and is used for interacting with the user. The operation panel is communicatively connected to the main body of the water purification device to realize the transmission of interaction instructions.
