Description

Technical Field

[0001] This invention relates to the field of water purification equipment technology, and in particular to a water purifier. Background Technology

[0002] Water purifiers are widely used drinking water devices that provide people with direct drinking water. As people's living standards improve, their requirements for drinking water are becoming increasingly diverse. Hydrogen-rich water, due to its antioxidant and anti-inflammatory effects, has become an important function of water purifiers. Existing water purifiers achieve this hydrogen-rich function by adding a hydrogen-rich cup.

[0003] Patent CN221876713U discloses a water purification device with a hydrogen-rich cup mounted on the casing of the main unit. The hydrogen-rich cup includes a cup assembly and a hydrogen-rich component, which are detachably mounted on the cup assembly. The cup assembly is fixed to the casing of the main unit with screws. A motor in the hydrogen-rich component ionizes the water, generating hydrogen ions, thus making the water hydrogen-rich. However, this technical solution only allows the hydrogen-rich component to be detached from the cup assembly; the entire hydrogen-rich cup cannot be quickly removed from the main unit. Removing the entire hydrogen-rich cup requires disassembling the entire water purifier, which not only increases the complexity and difficulty of operation but also increases maintenance time and cost, hindering quick replacement and cleaning.

Therefore, a feature specified as "first" or "second" can explicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two; "several" means at least one; unless otherwise expressly defined.

[0115] In this invention, "first direction a" and "second direction b" both refer to... Figure 1 The markings in the text shall prevail.

[0116] The following is based on Figures 1 to 17 The water purifier of the present invention is described in detail.

[0117] In this embodiment, such as Figure 1 , Figure 2 and Figure 5 As shown, the water purifier 100 includes a main unit 1, a hydrogen-rich cup assembly 2, and a locking mechanism 3. The hydrogen-rich cup assembly 2 is detachably connected to the main unit 1. The main unit 1 provides filtered water to the hydrogen-rich cup assembly 2. The hydrogen-rich cup assembly 2 is used to convert the filtered water into hydrogen-rich water. The hydrogen-rich water formed by the hydrogen-rich cup assembly 2 flows into the water supply port 112 of the main unit 1 through a pipe and is supplied to the outside through the water supply port 112.

[0118] The locking mechanism 3 has a locked state and an unlocked state. When the hydrogen-rich cup assembly 2 is connected to the host 1 and the locking mechanism 3 is in the locked state, the locking mechanism 3 prevents the hydrogen-rich cup assembly 2 from detaching from the host 1 and locks the hydrogen-rich cup assembly 2 to the host 1 to ensure a stable connection between the two. When the locking mechanism 3 switches to the unlocked state, the locking mechanism 3 releases the restriction, allowing the hydrogen-rich cup assembly 2 to detach from the host 1. At this time, the hydrogen-rich cup assembly 2 can be removed from the host 1.

[0119] The above technical solution adds a locking mechanism 3 to the water purifier 100. When the hydrogen-rich cup component 2 is installed on the main unit 1, the locking mechanism 3 is used to ensure that the hydrogen-rich cup component 2 and the main unit 1 can be stably connected. When the locking mechanism 3 is released, the hydrogen-rich cup component 2 can be quickly removed from the main unit 1. The disassembly operation of the hydrogen-rich cup component 2 is simple and quick, which is conducive to the rapid replacement and cleaning of the hydrogen-rich cup component 2 and reduces the maintenance time and cost of the hydrogen-rich cup component 2.

[0120] In one embodiment, when the locking mechanism 3 switches between a power-off mode and a power-on mode, the locking mechanism 3 switches between a locked state and an unlocked state. The locking mechanism 3 can lock when powered on and unlock when powered off, or it can unlock when powered on and lock when powered off, which is convenient to operate.

[0121] Furthermore, the locking mechanism 3 is an electromagnetic lock, which has a fast response, simple structure, and convenient maintenance.

[0122] In one implementation, such as Figures 2 to 4 As shown, the locking mechanism 3 is installed on the housing 11 of the host 1. The installation structure of the locking mechanism 3 is set on the housing 11. Compared with setting the installation structure on other parts of the host 1, the modification cost of the housing 11 is lower.

[0123] In one implementation, such as Figures 1 to 5As shown, the locking mechanism 3 includes a locking pin 31, which can move along a first direction a to switch between a locked position and an unlocked position. When the locking pin 31 is in the locked position, it prevents the hydrogen-rich cup assembly 2 from detaching from the main unit 1, and the locking mechanism 3 locks the hydrogen-rich cup assembly 2 via the locking pin 31. When the locking mechanism 3 switches from the locked state to the unlocked state, the locking pin 31 in the locked position begins to move. When the locking pin 31 moves to the unlocked position, it releases the restriction on the hydrogen-rich cup assembly 2, and the hydrogen-rich cup assembly 2 can be disassembled.

[0124] Furthermore, such as Figure 1 and Figure 4 As shown, the hydrogen-rich cup assembly 2 is mounted and dismounted from the host 1 along the second direction b. The first direction a intersects with the second direction b. When the locking pin 31 moves to the locking position along the first direction a, the locking pin 31 is at least partially blocked on the movement path of the hydrogen-rich cup assembly 2 leaving the host 1, thereby restricting the hydrogen-rich cup assembly 2 from leaving the assembly 1.

[0125] Furthermore, the angle between the first direction a and the second direction b is 85°-95°. Preferably, as shown below... Figure 1 As shown, the angle between the first direction a and the second direction b is 90°. For example, the hydrogen-rich cup assembly 2 is installed on the main unit 1 in the horizontal direction, and the locking pin 31 moves in the vertical direction to switch between the locked position and the unlocked position. Alternatively, the hydrogen-rich cup assembly 2 is installed on the main unit 1 in the vertical direction, and the locking pin 31 moves in the horizontal direction to switch between the locked position and the unlocked position.

[0126] In one implementation, such as Figure 1 As shown, the first direction a is the vertical direction of the main unit 1, and the second direction b is the front-back direction of the main unit 1. Specifically, since the hydrogen-rich cup assembly 2 has a certain height and the space of the main unit 1 in the vertical direction is limited, it is not convenient to install the hydrogen-rich cup assembly 2 along the vertical direction of the main unit 1. Therefore, the hydrogen-rich cup assembly 2 is installed and removed from the main unit 1 along the front-back direction of the main unit 1 to facilitate assembly.

[0127] In one implementation, such as Figures 2 to 4 As shown, the locking mechanism 3 is located above the hydrogen-rich cup assembly 2 and at least partially within the housing 11 of the main unit 1. Of course, the location of the locking mechanism 3 is not limited to this; the locking mechanism 3 can also be located on one side or below the hydrogen-rich cup assembly 2, or it can be entirely within the housing 11 or completely outside the housing 11.

[0128] Furthermore, such as Figure 1 and Figure 2As shown, the upper front part of the housing 11 includes a protruding housing portion 111. The water inlet 112 of the main unit 1 is connected to the lower part of the protruding housing portion 111. When the user needs to fill the water container, they place a water cup or kettle under the protruding housing portion 111 and align the water inlet with the water inlet 112. Of course, there can be one water inlet 112, which can supply both purified water and hydrogen-rich water. There can also be two or more water inlets 112, with one water inlet for purified water and one for hydrogen-rich water. The hydrogen-rich cup assembly 2 is located below the protruding housing portion 111. By utilizing the empty space below the protruding housing portion 111 to accommodate the hydrogen-rich cup assembly 2, the lateral dimension of the water purifier 100 can be reduced or avoided due to the configuration of the hydrogen-rich cup assembly 2. The locking mechanism 3 is located at least partially in the cavity of the protruding housing portion 111. On the one hand, it can improve the appearance of the water purifier 100 after the hydrogen-rich cup assembly 2 is removed. On the other hand, it avoids the locking mechanism 3 being located too much on the outside of the housing 11, which would restrict the installation space of the hydrogen-rich cup assembly 2.

[0129] Furthermore, such as Figure 1 , Figure 2 and Figure 5 As shown, the housing 11 includes a front mounting plate 113, which is located below the protruding housing portion 111. The hydrogen-rich cup assembly 2 is embedded in the outer wall of the front mounting plate 113. Specifically, the front surface of the front mounting plate 113 is recessed inward to form a recess 1131, and the hydrogen-rich cup assembly 2 is at least partially embedded in the recess 1131. By partially enclosing the hydrogen-rich cup assembly 2 with the front mounting plate 113, the installation stability of the hydrogen-rich cup assembly 2 can be improved, and the size of the hydrogen-rich cup assembly 2 protruding from the housing 11 can be reduced, thus improving the aesthetic appearance of the water purifier 100.

[0130] In one implementation, such as Figure 1 As shown, the main unit 1 also includes a display screen 12, which is mounted on the outer wall of the protruding housing 111. The display screen 12 can be used to display information parameters of the water purifier 100, such as water temperature and water supply mode, and can also be used for users to input commands by touch.

[0131] In one embodiment, the locking mechanism 3 is an electromagnetic lock, such as... Figure 3 , Figure 4 , Figure 9 and Figure 10 As shown, the locking mechanism 3 also includes an electromagnet 32, the locking pin 31 is made of iron, the electromagnet 32 ​​has a receiving cavity 321, and the electromagnet 32 ​​can generate a magnetic field using electric current. Figure 4As shown, when the locking pin 31 is in the locked position, it is partially or completely located outside the receiving cavity 321. When the locking pin 31 moves from the locked position to the unlocked position (not shown in the figure), it moves away from the hydrogen-rich cup assembly 2 and is inserted into the receiving cavity 321, that is, the locking pin 31 moves along the direction of insertion into the receiving cavity 321 (e.g., ...). Figure 4 (As shown in the upward direction) the accommodating cavity 321 is used to receive the locking pin 31 to allow the locking pin 31 to move.

[0132] Furthermore, when the locking mechanism 3 is in the power-off mode, the locking pin 31 is in the locked position; when the locking mechanism 3 switches to the power-on mode, the electromagnet 32 ​​generates a magnetic attraction force. Under the attraction force generated by the electromagnet 32, the locking pin 31 moves from the locked position to the unlocked position to release the lock on the hydrogen-rich cup assembly 2. At this time, the hydrogen-rich cup assembly 2 can be removed from the main unit 1. After the hydrogen-rich cup assembly 2 is reinstalled on the main unit 1, the power to the locking mechanism 3 is turned off, and the locking mechanism 3 locks the hydrogen-rich cup assembly 2 again.

[0133] Furthermore, such as Figure 4 and Figure 10 As shown, the locking mechanism 3 also includes a reset elastic element 34, one end of which is connected to the locking pin 31. The connection method between the two includes, but is not limited to, abutment, latching, and snapping. When the locking mechanism 3 is in the energized mode, the locking pin 31 can be stably positioned in the unlocked position under the magnetic attraction force generated by the electromagnet 32, and the reset elastic element 34 is in a compressed state and storing force. When the locking mechanism 3 switches to the de-energized mode, the attraction force applied by the electromagnet 32 ​​to the locking pin 31 disappears, and the reset elastic element 34 rebounds, driving the locking pin 31 from the unlocked position to the locked position.

[0134] Furthermore, such as Figure 4 As shown, the locking pin 31 has an abutment boss 311. One end of the reset elastic member 34 abuts against the abutment boss 311, and the other end abuts against the electromagnet 32. When the locking pin 31 is in the unlocked position, the distance between the abutment boss 311 and the electromagnet 32 ​​is small, and the abutment boss 311 presses against one end of the reset elastic member 34, so that the reset elastic member 34 is in a compressed state. When the locking mechanism 3 switches to the power-off mode, the reset elastic member 34 pushes the abutment boss 311 to push the locking pin 31 to the locked position.

[0135] Furthermore, such as Figure 4 As shown, the reset elastic element 34 is a spring with a simple structure, and it is sleeved on the outer periphery of the locking pin 31. Preferably, the reset elastic element 34 is a tower spring, with its small end abutting against the abutting boss 311 and its large end abutting against the electromagnet 32. The tower spring has a large load capacity and stable elastic force, which is beneficial to extending the service life of the locking mechanism 3.

[0136] In one implementation, such as Figures 3 to 5 , Figure 12 As shown, the hydrogen-rich cup assembly 2 includes a cup structure 21 and a hydrogen-rich module 22. The cup structure 21 includes a cup body 211 and a lid 212. The cup body 211 and the lid 212 are at least partially detachably connected and together form a cavity. The internal cavity of the cup structure 21 can be cleaned by opening the lid 212. The hydrogen-rich module 22 is located in the cavity and is used to ionize water and form hydrogen-rich water.

[0137] Furthermore, such as Figure 4 and Figure 5 As shown, the cover 212 is provided with a locking hole 21221. (As indicated...) Figure 4 As shown, when the locking pin 31 is in the locked position, it is inserted into the lock hole 21221 to lock the hydrogen-rich cup assembly 2 to the main unit 1. When the locking pin 31 moves from the locked position to the unlocked position, it disengages from the lock hole 21221, thereby releasing the locking mechanism 3 from locking the hydrogen-rich cup assembly 2. In this solution, the locking mechanism 3 cooperates with the lock hole 21221 of the hydrogen-rich cup assembly 2 to achieve locking and unlocking. The structure is simple, the operating principle is simple, and the lock hole 21221 is set on the cover 212, which has a compact structure and low structural modification cost.

[0138] Furthermore, such as Figure 4 As shown, the outer wall of the cover 212 is concave inward to form a locking hole 21221, which is easy to process. Furthermore, the locking hole 21221 is a blind hole and does not communicate with the internal cavity of the cup structure 21, thus avoiding any impact on the sealing performance of the cup structure 21 due to the design of the locking hole 21221. Figure 5 As shown, the lock hole 21221 is located at the center of the cover 212. The distances between the lock hole 21221 and various points on the outer peripheral wall of the cover 212 are equal or have small differences. Thus, when the locking pin 31 is inserted into the lock hole 21221, if the hydrogen-rich cup assembly 2 tends to detach from the main unit 1 due to external force, an interaction force is generated between the lock hole 21221 and the cover 212. At this time, since the lock hole 21221 is located at the center of the cover 212, the cover 212 is not easily deformed, thereby extending the service life of the cover 212.

[0139] In one implementation, such as Figure 1 and Figure 2 As shown, the locking mechanism 3 is located inside the housing 11, and the hydrogen-rich cup assembly 2 is located outside the main unit 1 for easy installation and removal. When the locking pin 31 is in the locked position, the locking pin 31 passes through the housing 11 of the main unit 1 and is inserted into the lock hole 21221.

[0140] Furthermore, such as Figure 4 and Figure 11As shown, the housing 11 has a channel 1111 and a first through hole 1112 that are interconnected. The channel 1111 is positioned opposite the receiving cavity 321, and the locking pin 31 is movably inserted into the channel 1111. At least one of the channel 1111 and the first through hole 1112 is used to guide the locking pin 31 to move along a first direction a, guide the locking pin 31 to switch between a locked position and an unlocked position, and prevent the locking pin 31 from moving in other directions. When the locking pin 31 is in the locked position, the locking pin 31 passes through the first through hole 1112 and is inserted into the lock hole 21221.

[0141] Furthermore, such as Figure 10 and Figure 11 As shown, the cross-section of the first through hole 1112 is not circular. The first through hole 1112 matches the shape of the locking pin 31 to guide the locking pin 31 to switch between the locked and unlocked positions. The cross-sectional shape of the first through hole 1112 includes, but is not limited to, regular or irregular shapes such as D-shape, triangle, square, and ellipse. In one specific embodiment, as... Figure 4 As shown, since the outer periphery of the locking pin 31 is fitted with a reset elastic element 34, the lateral dimension of at least part of the channel 1111 needs to be larger than the lateral dimension of the locking pin 31. In this way, a gap can be left between the channel 1111 and the locking pin 31 to accommodate the reset elastic element 34. If part of the channel 1111 is configured to fit the shape of the locking pin 31 to guide the locking pin 31 to switch between the locked and unlocked positions, the length of the channel 1111 and the locking pin 31 will be extended, and the path length that the locking pin 31 needs to move when switching between the locked and unlocked positions will also be increased. This is not conducive to the miniaturization design of the locking mechanism 3 and increases the space occupied by the locking mechanism 3. Therefore, this solution guides the movement direction of the locking pin 31 through the first through hole 1112, which is conducive to the compact structure of the locking mechanism 3.

[0142] Furthermore, the maximum lateral dimension of the locking pin 31 is larger than the diameter of the first through hole 1112, to prevent the locking pin 31 from disengaging from the channel 1111 at the first through hole 1112. In one specific embodiment, as... Figure 4 As shown, the lateral dimension of the abutment boss 311 is larger than the diameter of the first through hole 1112, to prevent the locking pin 31 from disengaging from the channel 1111 at the first through hole 1112. Further, as... Figure 4 As shown, the housing 11 is provided with an annular protrusion 1113, which is located in the channel 1111. The inner wall of the annular protrusion 1113 and the hole wall of the first through hole 1112 have the same shape, the same size, and are opposite in position. The abutting boss 311 abuts against the end of the annular protrusion 1113 away from the first through hole 1112 to prevent the locking pin 31 from disengaging from the channel 1111 at the first through hole 1112.

[0143] In one implementation, such as Figure 4 , Figure 5 and Figure 12 As shown, the cover 212 includes a first cover 2121 and a second cover 2122. A locking hole 21221 is provided on the second cover 2122. The first cover 2121 is annular and is fixed to the first end of the cup body 211 (e.g., by welding). The second cover 2122 is detachably installed on the first cover 2121. The first cover 2121 and the second cover 2122 cooperate to seal the first end of the cup body 211. When the inside of the cup structure 21 needs to be cleaned, the second cover 2122 can be removed. In this design, the cover 212 is set as a split structure. Opening the second cover 2122 is easier than opening the cover as a single component. In addition, when the wall of the locking hole 21221 wears due to long-term friction with the locking pin 31, the second cover 2122 can be replaced to ensure the stability of the locking, reducing replacement costs.

[0144] Furthermore, such as Figure 4 As shown, the first cover 2121 has annular bosses 21211 and annular grooves 21212 sequentially distributed along the installation direction of the second cover 2122. The second cover 2122 has a cover plate 21222 and a snap-fit ​​post 21223. When the second cover 2122 is installed on the first cover 2121, the cover plate 21222 abuts against the annular bosses 21211, and the snap-fit ​​post 21223 snaps into the annular groove 21212, achieving quick assembly through snap-fit. A first sealing ring 2123 is provided between the snap-fit ​​post 21223 and the annular groove 21212 to seal the assembly gap between the first cover 2121 and the second cover 2122, ensuring the sealing performance of the cup structure 21.

[0145] In one implementation, such as Figure 3 , Figure 12 and Figure 16 As shown, the cup body 211 includes a first cup body 2111 and a second cup body 2112. The first cup body 2111 has a first cavity 21111, a first connecting port 21112, and a water outlet 21113. The cover 212 is installed on the top of the first cup body 2111. The second cup body 2112 is connected to the bottom of the first cup body 2111, which facilitates the rapid entry of purified water in the first cavity 21111 into the ionization chamber 221. The second cup body 2112 has a second cavity 21121, in which the hydrogen-rich module 22 is located.

[0146] like Figure 3 , Figure 12 , Figure 13 and Figure 15As shown, the hydrogen-rich module 22 includes an ionization chamber 221 and an electrode 222 located within the ionization chamber 221. The ionization chamber 221 is connected to a first cavity 21111 and is not connected to a second cavity 21121. The second cavity 21121 is also not connected to the first cavity 21111, meaning there is no water in the second cavity 21121. The hydrogen-rich module 22 includes a power connection structure 223, which is electrically connected to the electrode 222 via a wire 224. The main body of the power connection structure 223 and the wire 224 are located within the second cavity 21121. The purified water provided by the host 1 enters the ionization chamber 221 through the first connecting port 21112 and the first cavity 21111. In the ionization chamber 221, the purified water is ionized by the electrode 222 to generate hydrogen ions, thereby forming hydrogen-rich water. The hydrogen-rich water is discharged through the outlet 21113 to the water supply port 112 of the host 1, and then supplied to the outside through the water supply port 112.

[0147] In one implementation, such as Figure 12 , Figure 13 and Figure 15 As shown, the hydrogen-rich module 22 also includes a first housing 225 and a second housing 226. The first opening end 22511 of the first housing 225 communicates with the first cavity 21111, and the second opening end 2252 of the first housing 225 abuts against the second housing 226. The first housing 225 and the second housing 226 cooperate to form an ionization cavity 221. When assembling the hydrogen-rich module 22, the electrode 222 is first placed on the second housing 226, and then the first housing 225 and the second housing 226 are assembled. The connection methods between the first housing 225 and the second housing 226 include, but are not limited to, fastening with fasteners (such as bolts), screwing, and snapping. In this design, the outer shell of the hydrogen-rich module 22 is set as a split structure, which facilitates the installation of the electrode 222 into the outer shell of the hydrogen-rich module 22.

[0148] Furthermore, such as Figure 15 As shown, the lateral dimension of the first opening end 22511 of the first housing 225 is smaller than the lateral dimension of the second opening end 2252, and the lateral dimension of the electrode 222 is larger than the lateral dimension of the second opening end 2252. A snap ring 2253 is provided inside the second opening end 2252, and the electrode 222 is snapped into the snap ring 2253.

[0149] Furthermore, such as Figure 13 As shown, the first housing 225 has a pressing rib 2254 inside. The pressing rib 2254 abuts against the front of the electrode 222 to press the electrode 222 against the second housing 226 and prevent the middle of the electrode 222 from warping up.

[0150] In one implementation, such as Figures 13 to 15As shown, the bottom end of the first cup body 2111 is provided with a first hollow column 21115, and the top end of the first shell 225 is provided with a second hollow column 2251. The port of the second hollow column 2251 forms a first open end 22511. The second hollow column 2251 is inserted into the first hollow column 21115, and the two are sealed by a second sealing ring 23.

[0151] In one implementation, such as Figure 14 As shown, the bottom of the first cup body 2111 is provided with a bottom plate 21116, the bottom plate 21116 is provided with a second through hole 211161, and the second through hole 211161 is provided with a flow-disrupting rib 211162. When the water in the first cavity 21111 passes through the second through hole 211161 to flow into the ionization cavity 221, the water flow comes into contact with the flow-disrupting rib 211162 and changes its flow direction, which is conducive to accelerating the mixing of hydrogen gas generated by ionization with water.

[0152] In one implementation, such as Figure 12 As shown, the second cup body 2112 has an open structure at the top, and the open outline of the second body 2112 abuts against the bottom plate 21116 of the first cup body 2111. The bottom end of the first cup body 2111 has a first notch 21117, and the top end of the second cup body 2112 has a second notch 21122. The first notch 21117 and the second notch 21122 cooperate to form an insertion port for the power docking structure 223 of the hydrogen-rich module 22 to pass through.

[0153] In one implementation, such as Figure 6 , Figure 8 and Figure 12 As shown, the main unit 1 also includes a purified water tank 14 and a filter assembly 6. Water purified by the filter assembly 6 flows into the purified water tank 14 or the water level detection box 15. The first connecting port 21112 is connected to the outlet of the purified water tank 14 or the outlet of the water level detection box 15, and the purified water tank 14 or the water level detection box 15 provides purified water to the hydrogen-rich cup assembly 2. The first cup body 2111 is provided with a second connecting port 21114 to balance the air pressure in the cup structure 21, so as to ensure that water can flow smoothly into or out of the cup structure 21.

[0154] Furthermore, such as Figure 6 and Figure 8 As shown, the second connection port 21114 is connected to the air pressure balance pipe 13 in the host 1. The original air pressure balance pipe 13 of the host 1 is used to maintain the air pressure balance in the cup structure 21. There is no need to set up an additional air pressure balance pipe 13, thus reducing the number of structural components.

[0155] In yet another implementation, such as Figure 16 and Figure 17As shown, the host 1 also includes a filter element assembly 6, and the first communication port 21112 is connected to the outlet of the filter element assembly 6. The purified water formed by the filter element assembly 6 is directly supplied to the hydrogen-rich cup assembly 2.

[0156] Furthermore, such as Figure 16 and Figure 17 As shown, the main unit 1 also includes a purified water tank 14. The first cup body 2111 is also provided with a second connecting port 21114, which is connected to the purified water tank 14. The filter element assembly 6 provides purified water to the hydrogen-rich cup assembly 2. The hydrogen-rich water formed in the hydrogen-rich cup assembly 2 enters the purified water tank 14, which stores the hydrogen-rich water until the water level in the purified water tank 14 reaches a preset high value, at which point the filter element assembly 6 stops supplying purified water to the hydrogen-rich cup assembly 2. When the hydrogen-rich cup assembly 2 supplies hydrogen-rich water, the hydrogen-rich water in the purified water tank 14 enters the hydrogen-rich cup assembly 2 through the second connecting port 21114 to replenish the hydrogen-rich cup assembly 2. When the water level in the purified water tank 14 is lower than the preset high value, the filter element assembly 6 continues to supply purified water to the hydrogen-rich cup assembly 2. The hydrogen-rich cup assembly 2 converts the purified water into hydrogen-rich water and then flows into the purified water tank 14 for storage, so that the water level in the purified water tank 14 reaches the preset high value again.

[0157] Furthermore, such as Figure 16 and Figure 17 As shown, the hydrogen-rich cup assembly 2 is connected to the purified water tank 14 through the second connecting port 21114 to maintain the gas pressure balance in the cup structure 21. This eliminates the need for an additional vent in the hydrogen-rich cup assembly 2, reducing the number of gas pipes. Specifically, as the purified water from the filter assembly 6 enters the hydrogen-rich cup assembly 2, the gas in the cup structure 21 enters the purified water tank 14 along with the formed hydrogen-rich water, achieving gas pressure balance in the cup structure 21. To ensure the stability of the water purifier 100's center of gravity, the hydrogen-rich cup assembly 2, the purified water tank 14, and the filter assembly 6 are arranged sequentially from front to back along the water purifier 100. The second connecting port 21114 and the purified water tank 14 are arranged compactly, with a short connecting pipe between them. This facilitates the rapid entry of gas from the hydrogen-rich cup assembly 2 into the purified water tank 14, ensuring smooth venting and thus accelerating the water intake speed through the first connecting port 21112.

[0158] In one implementation, such as Figure 6 As shown, the hydrogen-rich cup assembly 2 also includes a lamp assembly 24, a lamp panel 241 and a lamp holder 242. The lamp panel 241 is mounted on the lamp holder 242. The cup body 211 is a transparent structure. The light emitted from the lamp panel 241 enters the cup body 211 to create a light atmosphere.

[0159] In one implementation, such as Figure 2 , Figure 5 and Figure 10As shown, the locking mechanism 3 also includes a mounting shell 33, which is connected to the main unit 1. The mounting shell 33 and the main unit 1 are installed using methods including, but not limited to, fastening with fasteners (such as bolts) or snap-fitting. The electromagnet 32 ​​is mounted on the mounting shell 33, and the lamp holder 242 is sandwiched between the mounting shell 33 and the cover 212 of the cup structure 21. Further, as... Figure 4 and Figure 10 As shown, the mounting shell 33 has a cover structure. The mounting shell 33 and the inner wall of the housing 11 of the main unit 1 together form a receiving cavity 4. The electromagnet 32 ​​is housed in the receiving cavity 4. In this way, the mounting shell 33 can also play a protective role, preventing the coil of the electromagnet 32 ​​from being bumped during the assembly of the water purifier 100, which would damage the coil and affect the locking function.

[0160] Furthermore, such as Figure 9 and Figure 10 As shown, the mounting housing 33 has a first recess 331, and the electromagnet 32 ​​is snapped into the first recess 331, thus facilitating the installation and removal of the electromagnet 32. Furthermore, to ensure a stable snap-fit ​​between the electromagnet 32 ​​and the first recess 331, certain precision is required in the machining of the surface of the electromagnet 32 ​​and the wall of the first recess 331. To reduce the precision requirements for the machining of the electromagnet 32 ​​and the first recess 331, this design provides multiple first abutment ribs 3311 on the inner wall of the first recess 331. The first recess 331 abuts against the outer wall of the electromagnet 32 ​​through the first abutment ribs 3311, achieving snap-fit. By reducing the contact area between the first recess 331 and the electromagnet 32, the precision requirements for the machining of the electromagnet 32 ​​and the first recess 331 can be reduced.

[0161] Furthermore, such as Figure 4 and Figure 9 As shown, the first sidewall 332 of the mounting housing 33 is provided with a first opening 3321, which is opposite to the first cavity 331. When the electromagnet 32 ​​is installed into the mounting housing 33, the first opening 3321 can be used to observe whether the electromagnet 32 ​​is installed in place. In addition, the setting of the first opening 3321 can improve the deformability of the first sidewall 332. In this way, by configuring the lateral dimension of the first cavity 331 to be slightly smaller than the lateral dimension of the electromagnet 32, when the electromagnet 32 ​​is snapped into the first cavity 331, the first sidewall 332 is slightly stretched. When the electromagnet 32 ​​is snapped into place, the deformation force of the first sidewall 332 returning to its original position is applied to the electromagnet 32, thereby improving the stability of the snapping between the first cavity 331 and the electromagnet 32. Of course, the scheme of creating an opening on the side wall of the mounting shell 33 is not limited to creating the first opening 3321 only on the first side wall 332 of the mounting shell 33. Openings can also be created on other side walls of the mounting shell 33, for example, Figure 7As shown, a second opening 3341 is formed on the second side wall 334 of the mounting shell 33. The function of the second opening 3341 is the same as that of the first opening 3321.

[0162] In one embodiment, the locking mechanism 3 further includes a controller (not shown in the figure), which controls the energization or de-energization of the locking mechanism 3. The display screen 12 is electrically connected to the controller. Figure 1 As shown, the display screen 12 is used to input the unlock command to trigger the locking mechanism 3 to release the hydrogen-rich cup component 2. Users can unlock the device by operating the display screen 12, which is convenient.

[0163] In one implementation, such as Figure 4 and Figure 10 As shown, the water purifier 100 also includes an installation detection element 5. When the installation detection element 5 detects that the hydrogen-rich cup assembly 2 has been installed, it de-energizes the locking mechanism 3, and the locking pin 31 moves to be inserted into the lock hole 21221. The locking mechanism 3 switches from the unlocked state to the locked state to lock the hydrogen-rich cup assembly 2.

[0164] Furthermore, when the installation detection element 5 detects that the hydrogen-rich cup assembly 2 is not properly installed, the water purifier 100 will not perform water production to prevent leakage. Conversely, when the installation detection element 5 detects that the hydrogen-rich cup assembly 2 is properly installed, the water purifier 100 can perform water production. Water production refers to the action of the water purifier 100 filtering and purifying raw water to produce purified water. If the water purifier 100 performs water production when the hydrogen-rich cup assembly 2 is not properly installed, it will cause leakage at the connection point between the main unit 1 and the hydrogen-rich cup assembly 2.

[0165] In one implementation, such as Figure 5 and Figure 10 As shown, the installation detection element 5 is a micro switch. When the hydrogen-rich cup assembly 2 is installed in place, the switch button 51 of the micro switch is pressed by the cover 212 of the cup structure 21. The installation detection element 5 determines that the hydrogen-rich cup assembly 2 has been installed in place, and the controller controls the locking mechanism 3 to be energized to lock the hydrogen-rich cup assembly 2.

[0166] like Figure 9 and Figure 10 As shown, the mounting housing 33 also has a second recess 333. The positioning detection element 5 is snapped into the mounting housing 33, making installation convenient and eliminating the need for additional mounting parts. The inner wall of the second recess 333 has a second abutting rib 3331. The second recess 333 abuts against the outer wall of the positioning detection element 5 through the second abutting rib 3331 to achieve a snap-fit. This reduces the contact area between the second recess 333 and the positioning detection element 5, thereby reducing the requirements for the surface machining accuracy of the second recess 333 and the positioning detection element 5.

[0167] In another embodiment, the installation detection element 5 is an in-position induction switch (not shown in the figure). The in-position induction switch includes a matching magnet and a reed switch. The magnet is disposed on the hydrogen-rich cup assembly 2, and the reed switch is disposed on the host 1. When the hydrogen-rich cup assembly 2 is installed in place, the magnetic field of the magnet triggers the reed switch, and the in-position induction switch determines that the hydrogen-rich cup assembly 2 has been installed in place.

[0168] In one implementation, such as Figures 6 to 8 As shown, the power connection structure 223 of the hydrogen-rich cup assembly 2 is used to electrically connect to the power supply module of the host 1. Compared with the scheme in CN221876713U where the male terminal of the hydrogen-rich assembly is matched with the female terminal of the cup assembly to connect to the power supply, the power connection structure 223 of the hydrogen-rich cup assembly 2 in this scheme is directly connected to the host 1 to connect to the power supply, which simplifies the structure of the cup structure 21.

[0169] In one embodiment, the hydrogen-rich cup assembly 2 is plugged into the main unit 1, and the hydrogen-rich cup assembly 2 is easy to install and remove.

[0170] Furthermore, such as Figure 6 and Figure 7 As shown, the hydrogen-rich cup assembly 2 is embedded in the outer wall of the housing 11 of the main unit 1, and the hydrogen-rich cup assembly 2 and the main unit 1 are connected by water circuit connection and / or electrical circuit connection and / or gas circuit connection.

[0171] Furthermore, to improve the stability of the connection between the hydrogen-rich cup assembly 2 and the main unit 1, the hydrogen-rich cup assembly 2 and the main unit 1 are connected via water path connection, electrical path connection, and gas path connection. Specifically, the main unit 1 supplies water to the hydrogen-rich cup assembly 2 via the water path connection, supplies power to the hydrogen-rich cup assembly 2 via the electrical path connection, and the hydrogen-rich cup assembly 2 maintains the gas pressure balance in the first cavity 21111 and the ionization cavity 221 via the water / gas path connection. Specifically, as shown... Figure 6 , Figure 12 and Figure 16 As shown, the hydrogen-rich cup assembly 2 has a first connecting port 21112, a water outlet 21113, a second connecting port 21114, and a power connection structure 223 on its rear side. These four components are respectively plugged into the main unit 1. Furthermore, as shown... Figure 8 and Figure 17As shown, the first connecting port 21112 is connected to the water supply pipe in the main unit 1 (for example, the first connecting port 21112 is connected to the outlet of the purified water tank 14 or the outlet of the filter element assembly 6). The water outlet 21113 is connected to the water supply port 112 of the main unit 1 through a pipe. The second connecting port 21114 is connected to the air pressure balance pipe 13 in the main unit 1 or the second connecting port 21114 is connected to the purified water tank 14 of the main unit 1. The power connection structure 223 is connected to the power supply module in the main unit 1 through a wire. In the prior art CN221876713U, the connector is located above the cup assembly, and the first water inlet and outlet are located on the rear side of the cup assembly. This makes it impossible for the hydrogen-rich cup to be detachably connected to the housing. However, in this solution, the first connecting port 21112, the water outlet 21113, the second connecting port 21114, and the power connection structure 223 are all located on the rear side of the hydrogen-rich cup assembly 2, which facilitates the detachable connection between the hydrogen-rich cup assembly 2 and the main unit 1.

[0172] Furthermore, such as Figure 6 , Figure 12 and Figure 16 As shown, the first connecting port 21112 and the second connecting port 21114 are arranged side by side, the water outlet 21113 and the power connection structure 223 are arranged side by side, and the water outlet 21113 and the power connection structure 223 are located below the first connecting port 21112 and the second connecting port 21114.

[0173] In one implementation, such as Figure 6 and Figure 7 As shown, the front mounting plate 113 of the main unit 1 is provided with a first mounting port 1132, a second mounting port 1133, and a third mounting port 1134. The first mounting port 1132 is equipped with a main unit water supply connector 161, the second mounting port 1133 is equipped with a main unit gas circuit connector 171, and the third mounting port 1134 is equipped with a main unit water inlet connector 18 and a main unit power supply connector 19. The first connecting port 21112 is plugged into the main unit water supply connector 161, which is connected to the outlet of the purified water tank 14. The second connecting port 21114 is plugged into the main unit gas circuit connector 171, which is connected to the air pressure balance pipe 13 of the main unit 1. The water outlet 21113 is plugged into the main unit water inlet connector 18, and the power connection structure 223 is plugged into the main unit power supply connector 19, thereby realizing the connection between the hydrogen-rich cup assembly 2 and the front mounting plate 113. In addition, to simplify the number of parts, the main unit water supply connector 161 and the main unit air circuit connector 171 are integrated into one part, and the main unit water inlet connector 18 and the main unit power supply connector 19 are integrated into one part.

[0174] In yet another implementation, such as Figure 16As shown, the front mounting plate 113 of the main unit 1 has a first mounting port 1132, a second mounting port 1133, and a third mounting port 1134. The first mounting port 1132 houses a main unit water supply connector 162, the second mounting port 1133 houses a filter element water supply connector 172, and the third mounting port 1134 houses a main unit water inlet connector 18 and a main unit power supply connector 19. The first connecting port 21112 is plugged into the filter element water supply connector 172, which is connected to the filter element assembly 6. The second connecting port 21114 is plugged into the main unit water supply connector 162, which is connected to the purified water tank 14. The water outlet 21113 is plugged into the main unit water inlet connector 18, and the power connection structure 223 is plugged into the main unit power supply connector 19, thereby enabling the connection between the hydrogen-rich cup assembly 2 and the front mounting plate 113. In addition, to simplify the number of parts, the main unit water supply connector 162 and the filter element water supply connector 172 are integrated into one part, and the main unit water inlet connector 18 and the main unit power supply connector 19 are integrated into one part.

[0175] In one embodiment, the connector of the hydrogen-rich cup assembly 2 is a male connector, and the connector of the host 1 is a female connector.

[0176] In one implementation, such as Figure 8 As shown, the main unit 1 also includes a water tank 14, which is used to store purified water or hydrogen-rich water.

[0177] Furthermore, when the hydrogen-rich cup assembly 2 supplies hydrogen-rich water, the purified water tank 14 simultaneously supplies purified water to the hydrogen-rich cup assembly 2. That is, when hydrogen-rich water is taken out, the purified water tank 14 continuously replenishes purified water to the hydrogen-rich cup assembly 2. Thus, during the use of the water purifier 100, the hydrogen-rich cup assembly 2 is usually kept in a water state. To prevent water leakage from the main unit 1 after removing the hydrogen-rich cup assembly 2, the hydrogen-rich water in the hydrogen-rich cup assembly 2 must be drained before removing it until no more purified water flows into the hydrogen-rich cup assembly 2.

[0178] In one implementation, such as Figure 8 As shown, the main unit 1 also includes a water level detection box 15, which is connected to the purified water tank 14 and used to detect the water level in the purified water tank 14. Compared with the solution of configuring a water level detection element in the purified water tank 14, this solution does not require any modification to the structure of the purified water tank 14.

[0179] Furthermore, such as Figure 2 and Figure 8As shown, the water level detection box 15, the purified water tank 14, and the hydrogen-rich cup assembly 2 are connected in sequence. Specifically, in one embodiment, the purified water after filtration in the main unit 1 first flows into the water level detection box 15, and then into the purified water tank 14. When the hydrogen-rich cup assembly 2 supplies hydrogen-rich water, the purified water in the purified water tank 14 flows into the hydrogen-rich cup assembly 2. Furthermore, one end of the air pressure balance pipe 13 of the main unit 1 is connected to the water level detection box 15, and the other end is connected to the atmosphere. The second connection port 21114 of the hydrogen-rich cup assembly 2 is connected to the air pressure balance pipe 13 through an air pipe. The water level detection box 15 is connected to the atmosphere, and the water level in the water level detection box 15 can rise or fall smoothly, thereby obtaining the water level detection result. In another embodiment, the second connection port 21114 of the hydrogen-rich cup assembly 2 is connected to the water purification tank 14. The purified water after being filtered by the host 1 first flows into the hydrogen-rich cup assembly 2 through the first connection port 21112 to form hydrogen-rich water, and then flows into the water purification tank 14 through the second connection port 21114, and then flows into the water level detection box 15.

[0180] Furthermore, the water purifier 100 also includes a controller and a water pump (not shown in the figure). After receiving an instruction to disassemble the hydrogen-rich cup assembly 2, the controller controls the water pump to run, performing a drainage operation to empty the water in the hydrogen-rich cup assembly 2. After determining that the drainage operation of the water purifier 100 has been completed, the controller controls the locking mechanism 3 to switch to the unlocked state. Specifically, when the drainage operation of the water purifier 100 is completed, the user can input an unlock command through the display screen 12. The controller issues an unlock command, the main unit 1 supplies power to the electromagnet 32, and the locking pin 31 moves to the unlocked position under the attraction force of the electromagnet 32, thus unlocking the device. Conversely, if the drainage operation of the water purifier 100 has not been completed, the user can trigger the unlocking action through the display screen 12 to avoid water leakage caused by premature removal of the hydrogen-rich cup assembly 2.

[0181] Furthermore, during the drainage operation, when the water level in the clean water tank 14 is detected to have reached a low level, drainage continues until there is no water in the hydrogen-rich cup assembly 2, followed by a delay of t. m The time is determined to be [time] and the drainage of the hydrogen-rich cup component 2 is confirmed. Specifically, during the drainage process of the hydrogen-rich cup component 2, the clean water tank 14 continuously supplies clean water to the hydrogen-rich cup component 2. Since the water pump flow rate is fixed, the drainage and inflow of the hydrogen-rich cup component 2 are also fixed. Thus, in the initial stage of drainage, the water level in the hydrogen-rich cup component 2 will not change. When the water level in the clean water tank 14 reaches the low level, the clean water tank 14 stops supplying clean water to the hydrogen-rich cup component 2. At this time, the water in the hydrogen-rich cup component 2 continues to be discharged, and the water level in the hydrogen-rich cup component 2 will continue to drop until there is no water in the hydrogen-rich cup component 2. In order to ensure that the water in the water circuit connected to the main unit 1 and the hydrogen-rich cup component 2 is completely drained, a delay t is set. m The duration (e.g., 20 seconds) is then used to determine whether the hydrogen-rich cup component 2 has completed drainage.

[0182] Specifically, when the water level in the purified water tank 14 is detected to have reached a low level, the remaining water in the purified water tank 14 and the water level detection box 15 is discharged for a duration of t1. The drainage process continues until there is no water in the hydrogen-rich cup assembly 2; this stage of drainage takes t2. Therefore, the total drainage time of the water purifier 100 is t1 + t2 + t m .

[0183] In one embodiment, the display screen 12 is also used to prompt the user that the hydrogen-rich cup assembly 2 has finished draining. Specifically, when the hydrogen-rich cup assembly 2 has finished draining, the display screen 12 will provide an intuitive prompt. After receiving the prompt, the user can input an unlock command through the display screen 12. Under the unlock command issued by the controller, the locking mechanism 3 will release the lock on the hydrogen-rich cup assembly 2. At this time, the user can remove the hydrogen-rich cup assembly 2. The prompting methods of the display screen 12 include, but are not limited to, indicator lights (lights turning on or off, light colors changing, or light flashing patterns changing), text instructions, and icon instructions.

Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of the present invention that may not be explicitly described.
