[0136] 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.

[0137] In this embodiment, 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 this distance, space can be provided for disassembly and assembly of the hydrogen-rich component 23, which is convenient for operation.

[0138] In order to facilitate maintenance of the hydrogen-rich component 23, the hydrogen-rich component 23 and the cup component 21 can be detachably connected. Figure 6 , Figure 7 and Fig.10As shown, the hydrogen-rich component 23 includes a mounting flange 23212, and the mounting flange 23212 contains a reaction chamber 2320. The bottom of the cup component 21 is provided with a mounting groove 2121 that is connected to the interior of the cup component 21. The mounting flange 23212 can be inserted into the mounting groove 2121 and fixed with the mounting groove 2121 to fix the cup component 21 and the hydrogen-rich component 23.

[0139] Specifically, a latching protrusion 23213 is provided on the mounting flange 23212, and a latching groove 2122 is provided on the side wall of the mounting groove 2121. The latching groove 2122 includes a screw-in section 21221 and a latching section 21222 that are connected to each other. The screw-in section 21221 extends axially along the mounting groove 2121 and passes through the bottom end surface of the cup assembly 21, and the latching section 21222 extends circumferentially along the mounting groove 2121; the latching protrusion 23213 can enter the screw-in section 21221, and can enter the latching section 21222 from the screw-in section 21221 as the hydrogen-rich assembly 23 rotates, and fixes the hydrogen-rich assembly 23 to the cup assembly 21 by abutting against the side wall of the latching section 21222.

[0140] In some embodiments, the card slot 2122 can be set on the outer wall of the mounting flange 23212, and correspondingly, the card protrusion 23213 is set on the inner wall of the mounting slot 2121, which can also realize the card connection between the hydrogen-rich component 23 and the cup component 21.

[0141] In order to improve the fixing effect of the cup assembly 21 and the hydrogen-rich assembly 23, two slots 2122 are provided, and each slot 2122 is correspondingly provided with a latching protrusion 23213. The arrangement directions of the screw-in sections 21221 and the latching sections 21222 in the two slots 2122 are the same, so that the two latching protrusions 23213 can be synchronously latched into the corresponding slots 2122.

[0142] In other embodiments, the number of the card slots 2122 can be three, four or more, and the specific number can be selected according to actual needs.

[0143] To prevent water leakage at the connection between the hydrogen-rich component 23 and the cup component 21, a fourth seal 214 is provided between the mounting flange 23212 and the inner wall of the mounting groove 2121. The fourth seal 214 is clamped and deformed by the mounting flange 23212 and the mounting groove 2121 to block the safety gap between the two.

[0144] like Figure 7 As shown, the cup assembly 21 includes a cup body 211 and a cup seat 212. The bottom surface of the cup body 211 is provided with a through hole. The cup seat 212 is arranged on the bottom surface of the cup body 211, and the cup seat 212 is arranged circumferentially around the through hole. The fourth seal 214 can achieve sealing among the cup body 211, the cup seat 212 and the hydrogen-rich assembly 23.

[0145] Specifically, a positioning sleeve 2113 is further provided around the through hole on the bottom surface of the cup body 211, and the positioning sleeve 2113 forms a part of the side wall of the mounting groove 2121. The fourth sealing member 214 includes a top sealing portion, a side sealing portion and a bottom sealing portion connected in sequence, the top sealing portion can be pressed against the bottom surface of the cup body 211 by the mounting flange 23212, the side sealing portion can be clamped between the mounting flange 23212 and the positioning sleeve 2113, and the bottom sealing portion can be clamped between the positioning sleeve 2113 and the cup holder 212. 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.

[0146] In other embodiments, the fourth sealing member 214 may 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 may also be achieved.

[0147] like Figure 5 and Figure 8 As shown, the hydrogen-rich component 23 includes a hydrogen-rich shell 231, an electrode shell 232 and an electrode 233. The top of the hydrogen-rich shell 231 is open, and the electrode shell 232 is arranged in the hydrogen-rich shell 231. The electrode shell 232 includes an upper cover 2321 and a lower cover 2322. The upper cover 2321 is fixed to the lower cover 2322, and the electrode 233 is arranged between the upper cover 2321 and the lower cover 2322. The upper cover 2321 is provided with a central hole, and the upper cover 2321 is configured with a mounting flange 23212. The mounting flange 23212 is arranged around the circumference of the central hole. The mounting flange 23212 and the lower cover 2322 enclose a reaction chamber 2320. Pure water contacts the electrode 233 through the central hole in the reaction chamber 2320 to generate hydrogen ions. Optionally, the upper cover 2321 and the lower cover 2322 can be fixed by screws, which is convenient for disassembly and assembly.

[0148] In order to be able to carry out 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 cup 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.

[0149] To facilitate the energization of electrode 233, Figure 8As shown, the hydrogen-rich cup 20 also includes a conductive member, a male terminal 235 and a female terminal 236. An installation cavity is formed between the electrode shell 232 and the hydrogen-rich shell 231, and the male terminal 235 and the conductive member are arranged in the installation cavity. Two conductive members are provided, and the two conductive members respectively pass through the lower cover 2322 and contact the positive and negative electrodes of the electrode 233 to be electrically connected. The male terminal 235 can connect the two conductive members through a wire, and the female terminal 236 is arranged on the cup assembly 21 and connected to the main unit of the water purification device through a wire. When the cup assembly 21 is assembled with the hydrogen-rich assembly 23, the male terminal 235 can contact the female terminal 236, and the electrode 233 is powered by the main unit of the water purification device. When the hydrogen-rich assembly 23 is removed from the cup assembly 21, the female terminal 236 and the male terminal 235 are separated and automatically disconnected.

[0150] Since the hydrogen-rich component 23 and the cup component 21 are fixed by the protrusion 23213 and the slot 2122, and the protrusion 23213 is assembled with the slot 2122 by rotation, in order to ensure that the male terminal 235 can be connected with the female terminal 236 after being assembled in place, Fig. 9 As shown, a sliding hole 2312 extending along the height direction of the cup assembly 21 is provided in the hydrogen-rich shell 231, and the male terminal 235 includes a main body 2351, a coupling part 2353 and a sliding part 2352. The main body 2351 is provided in the hydrogen-rich shell 231 and can slide in the vertical direction. The sliding part 2352 is slidably provided in the sliding hole 2312, and part of the sliding part 2352 extends out of the hydrogen-rich shell 231 from the sliding hole 2312; the coupling part 2353 can be plugged and matched with the female terminal 236 to realize electrical connection and fixation. Before assembling the cup assembly 21 and the hydrogen-rich assembly 23, first slide the male terminal 235 downward by pushing the sliding part 2352, so that the coupling part 2353 can be retracted into the hydrogen-rich shell 231. After the hydrogen-rich component 23 and the cup component 21 are rotated and assembled, the male terminal 235 is slid upward by pushing the sliding part 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 component 23, the male terminal 235 is slid downward by pushing the sliding part 2352, so that the male terminal 235 is retracted into the hydrogen-rich shell 231, and then the hydrogen-rich component 23 and the cup component 21 can be disassembled by rotation.

[0151] 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.

[0152] 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.

[0153] In this embodiment, the male terminal 235 and the electrode 233 may be connected by a conductive member, which may be a wire. Fig.10 and Fig.11 As 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.

[0154] 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.

[0155] 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.

[0156] To prevent water leakage from the electrode shell 232, Fig.12 and Fig.13 As shown, the electrode shell 232 also includes a third seal 2323, which is sleeved on the circumferential edge of the electrode 233. The third 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 water leakage of the electrode shell 232.

[0157] Specifically, if Fig.13As shown, the third sealing member 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.

[0158] 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.

[0159] 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.14 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.

[0160] 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 .

[0161] 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 .

[0162] In some embodiments, the outer cover 234 and the cup assembly 21 are fixed by adsorption to improve the fixing effect of the two. Specifically, the outer cover 234 and the cup assembly 21 both include an adsorption member 213, and the adsorption members 213 can be adsorbed to each other to achieve fixation. Fig.15 As shown, the adsorbing member 213 in the cup assembly 21 is called a first magnetic member, which is disposed in the cup holder 212, and the adsorbing member 213 in the hydrogen-rich assembly 23 is called a second magnetic member, which can be disposed in the outer cover 234. The adsorbing members 213 in both the outer cover 234 and the cup assembly 21 can be magnets, or the adsorbing member 213 in one of the hydrogen-rich assembly 23 and the cup assembly 21 can be a magnet, and the adsorbing member 213 in the other can be an iron block.

[0163] 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.

[0164] In order to provide the amount of pure water that the water purification device can accommodate, the water purification device also includes a clean water tank 40, and a first water outlet 2111 is provided on the hydrogen-rich cup 20, and the first water outlet 2111 can be connected to the clean water tank 40. The pure water filtered by the filter component can enter the clean water tank 40 for storage after passing through the hydrogen-rich cup 20, so that both the hydrogen-rich cup 20 and the clean water tank 40 can store pure water, increasing the reserve of pure water to meet the needs of users. When the user needs water, the hydrogen-rich cup 20 supplies hydrogen-rich water to the water outlet structure 30. After the amount of pure water in the hydrogen-rich cup 20 is reduced, the clean water tank 40 can supply pure water to the hydrogen-rich cup 20.

[0165] The water purification device further 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. The first water outlet 2111 on the hydrogen-rich cup 20 is connected to 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 cup 20 smoother, the height of the water inlet 222 of the hydrogen-rich cup 20 connected to the pure water source is higher than the height of the first water outlet 2111.

[0166] 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.

[0167] In addition, the volume of the clean water 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 pure water provided by the hydrogen-rich cup 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.

[0168] Specifically, the clean water tank 40 includes a second water outlet, and the water level detection box 50 includes a third water outlet. The second water outlet and the third water outlet can be connected, and the second water outlet and the third water outlet 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 outlet 2111 of the hydrogen-rich cup 20 can sequentially connect the second water outlet and the third water outlet, so that the hydrogen-rich cup 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 cup 20 can first pass through the second water outlet, and then pass through the third water outlet, 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 cup 20 drops, the water in the clean water tank 40 and the water level detection box 50 can also flow to the first water outlet 2111 to supply water to the hydrogen-rich cup 20.

[0169] In order to allow the water in the clean water tank 40 and the water level detection box 50 to enter the hydrogen-rich cup 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.

[0170] 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. The assembly gap between the box body 41 and the box cover 42 can be used to connect the inside of the clean water tank 40 with the outside atmosphere. The water level detection box 50 is provided with a through hole, which is used to ensure that the water level detection box 50 is connected to the atmosphere. In other embodiments, the upper cover on the water level detection box 50 may also be incompletely sealed with the shell to achieve the connection between the water level detection box 50 and the atmosphere.

[0171] The hydrogen-rich cup 20 needs to electrolyze the pure water inside it to generate hydrogen ions, so the hydrogen-rich cup 20 is a sealed structure. In order to ensure the stability of the internal pressure, an exhaust port 221 is provided on the hydrogen-rich cup 20. 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 cup 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 cup 20. By utilizing the characteristic that the water level detection box 50 is connected to the atmosphere, the exhaust function of the hydrogen-rich cup 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 cup 20, which is conducive to simplifying the internal structure of the water purification device to reduce costs.

[0172] In order to prevent the water in the water level detection box 50 from flowing back into the hydrogen-rich cup 20 through the exhaust port 221 of the hydrogen-rich cup 20, the height of the exhaust port 221 on the hydrogen-rich cup 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 purification device, 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.

[0173] To simplify the structure of the hydrogen-rich cup 20, Figure 4 As shown, the hydrogen-rich cup 20 also includes a joint 22, which is connected to the cup assembly 21, and a flow channel is provided in the joint 22 to communicate with the interior of the cup assembly 21. The water inlet 222 and the exhaust port 221 are both provided on the joint 22 and communicate with the flow channel to facilitate the hydrogen-rich cup 20 to communicate with the pure water source and the water level detection box 50, respectively. Among them, the exhaust port 221 is higher than the water inlet 222 to facilitate smooth exhaust.

[0174] To further ensure the smoothness of exhaust from the hydrogen-rich cup 20, Fig.16 and Fig.17 As shown, the flow channel in the joint 22 extends in the height direction of the cup assembly 21, 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 cup 20, and the gas can be smoothly discharged from the hydrogen-rich cup 20.

[0175] 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 twice on the partition 223 .

[0176] In this embodiment, Fig.18 and Fig.19 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 cup 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.

[0177] 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 cup 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.

[0178] 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.

[0179] 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.

[0180] like Fig. 20 and Fig.21 As 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 cup 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.

[0181] 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 cup 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 cup 20, the clean water tank 40 and the water level detection box 50 can be connected, which is conducive to simplifying the structure.

[0182] like Fig. 22 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.

[0183] 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. 22 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.23 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.

[0184] 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.

[0185] 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.

[0186] 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.

[0187] 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.

[0188] In order to improve the stability of the movement of the water tank valve core 431, a limiting sleeve 411 is convexly provided on the bottom surface of the box body 41 around the second water outlet, the water tank valve core 431 is located in the limiting sleeve 411, and a limiting groove is provided 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. 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.

[0189] 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 .

[0190] 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.

[0191] 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 .

[0192] 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.

[0193] 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.

[0194] In some embodiments, two handles may be provided, and the two handles are rotatably disposed on opposite sides of the box cover 42 .

[0195] 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.

[0196] In this embodiment, the water purification device also includes a heater, and the water outlet structure 30 includes a normal temperature water inlet, a hot water inlet and a water supply outlet, which can provide normal temperature water and hot water to the user. The water outlet 2112 on the hydrogen-rich cup 20 is respectively connected to the normal temperature water inlet and the inlet of the heater, and the outlet of the heater is connected to the hot water inlet. The heater is used to heat pure water to supply hot water to the user.

[0197] In this embodiment, the hydrogen-rich cup 20 is provided with a first water inlet 2111 and a water outlet 2112. 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-rich cup 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-rich cup 20.

[0198] 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.

[0199] To solve the above problems, Fig.24As shown, the water purifier further includes a thermos cup 60, the outlet of the heater is connected to the thermos cup 60, and the outlet of the thermos cup 60 is connected to the inlet of the heater. By providing the thermos cup 60, 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 60. When the user needs high-temperature hot water, the warm water in the thermos cup 60 is passed into the heater for further heating, so as to reduce the waiting time of the user.

[0200] The water purification device further includes a sterilization mechanism, which can sterilize the purified water inside the water purification tank 40 when the water purification tank 40 is installed on the tank seat 70, so as to improve the user experience.

[0203] In order to prevent the water in the clean water tank 40 from contacting the germicidal lamp assembly 91 through the mounting hole, a sealing ring is provided between the bottom surface of the clean water tank 40 and the circuit protection shell 911 to seal the assembly gap.

[0204] In order to make the water purification device more intelligent, the water purification device further includes a detection trigger and a detection sensor. The detection trigger is arranged on the bottom surface of the circuit protection shell 911, and the detection sensor is arranged on the lamp holder 921. When the clean water tank 40 is installed in the box holder 70, the detection trigger can trigger the detection sensor, thereby judging whether the clean water tank 40 is installed in the box holder 70. When the clean water tank 40 is not installed in the box holder 70, the host of the water purification device sends a prompt message to remind the user to install the clean water tank 40.

[0205] Optionally, the detection triggering member may be a detection stylus, the detection sensing member may be a detection socket, and the detection socket may be connected in series in the detection circuit. When the detection stylus contacts the detection socket, the detection circuit is connected; when the detection stylus separates from the detection socket, the detection circuit is disconnected. Whether the clean water tank 40 is installed in the tank seat 70 can be detected by the on-off state of the detection circuit.

[0206] In some embodiments, the detection sensing element can be a proximity switch or a micro switch. When the clean water tank 40 is installed in the box seat 70, the detection trigger is within the detection range of the proximity switch or presses the reed of the micro switch to change the detection signal of the proximity switch or the micro switch, thereby determining whether the clean water tank 40 is installed in the box seat 70.
