The box includes a cavity and its side wall is provided with a fifth through hole. The cavity is connected to the purified water storage chamber through the fifth through hole.

[0178] The high water level detection mechanism includes a third float and a third liquid level sensor, the third float being located in the cavity.

[0180] Optionally, when the kettle is connected to the main unit and the water purifier is turned on to produce water, the purified water provided by the main unit flows into the kettle cavity through the water storage chamber.

[0182] When the kettle is connected to the main unit and the water purifier is turned on to produce water, the purified water provided by the main unit enters the purified water storage chamber through the container.

[0183] Optionally, when the kettle is connected to the main unit, the water collection component is located below the low limit position of the first float.

[0184] Optionally, the main unit includes a main unit base, and the kettle includes a detachably connected kettle body and kettle base, with the kettle base fixed to the main unit base.

[0188] This utility model provides a water purification device equipped with a functional water dispenser. Users can directly obtain purified water through the main unit or obtain functional water through the dispenser, offering richer functionality.

In addition, the water purification device is equipped with a water collection component, which connects the inlet water lines of both the purified water tank and the functional water dispenser. This reduces the number of pipes and joints, simplifies pipe layout, and consequently lowers the risk of pipe blockage and leakage at pipe joints. Attached Figure Description

[0214] The following is based on Figures 1 to 19 This utility model describes the water purification equipment in detail.

[0215] In this embodiment, such as Figure 1 , Figure 10 and Figure 16 As shown, the water purification device 100 includes a main unit 1 and a functional water dispenser 4. The main unit 1 includes a purified water tank 13 and a water collection component 18. The purified water tank 13 is used to store purified water. The functional water dispenser 4 is detachably connected to the main unit 1 and includes a functional water tank 41. The main unit 1 can be equipped with a filter element assembly 171, which is used to purify the raw water to form purified water for supply. Of course, the main unit 1 may not be equipped with a filter element assembly 171. The main unit 1 can store purified water or mineral water, or other water that the user considers clean, provided by the user. When the functional water dispenser 4 is connected to the main unit 1, the functional water tank 41 and the purified water tank 13 are respectively connected to the water collection component 18. When the purified water tank 13 needs to be replenished, purified water is distributed to the purified water tank 13 through the water collection component 18; when the functional water tank 41 needs to be replenished, purified water is distributed to the functional water tank 41 through the water collection component 18.

[0216] In the above technical solution, the water purification equipment 100, by configuring a functional water dispenser 4, allows users to directly access purified water through the main unit 1 and also access functional water through the functional water dispenser 4, thus enriching its functions. Furthermore, the main unit 1 supplies water to the functional water dispenser 4, eliminating the need for a separate functional water dispenser 4 structure, resulting in good integration and low cost. In addition, the water purification equipment 100 is also equipped with a water collection component 18. This component connects the water inlet to the purified water tank 13 and the functional water dispenser 4, reducing the number of pipes and pipe joints, simplifying pipe design, and thus reducing the risk of pipe blockage and the probability of pipe joint leakage to a certain extent.

[0217] In one implementation, such as Figure 10 and Figure 17 As shown, when the water purification device 100 is not in water production mode and the functional water tank 41 needs to be replenished, the purified water in the purified water tank 13 is distributed to the functional water tank 41 through the water collection component 18, and the functional water tank 41 can be replenished in time. Furthermore, when the water level in the purified water tank 13 drops to a low level, the water purification device 100 starts producing water. The purified water produced by the water purification device 100 first enters the water collection component 18, and then the purified water in the purified water tank 13 is replenished in time through the water collection component 18.

[0218] Furthermore, such as Figure 10 and Figure 17 As shown, the water purification device 100 also includes a filter element assembly 171. When the water purification device 100 is turned on to produce water, the filter element assembly 171 works to purify the raw water to produce purified water. In addition, when the water purification device 100 is in the water production state and the functional water tank 41 needs to be replenished, since the purified water tank 13 is connected to the water collection component 18, the purified water in the purified water tank 18 is drawn into the water collection component 18. At the same time, the purified water produced by the filter element assembly 171 also enters the water collection component 18. The two streams of purified water converge in the water collection component 18. That is, the purified water in the purified water tank 13 and the purified water produced by the filter element assembly 171 converge in the water collection component 18 and are distributed to the functional water tank 41 through the water collection component 18, which can quickly replenish the functional water tank 41.

[0219] Furthermore, such as Figure 10 As shown, the functional water dispenser 4 is also equipped with a water replenishment pump 44. Under the power provided by the water replenishment pump 44, the purified water in the main unit 1 is distributed to the functional water tank 41 through the water collection component 18.

[0220] In one embodiment, the number of functional water dispensers 4 is at least two (not shown in the figure), such as two or three. Due to the size limitation of the main unit 1, one or two functional water dispensers 4 are preferred. Different functional water dispensers can be configured according to needs, resulting in diversified functions. When the functional water dispensers 4 are connected to the main unit 1, all functional water dispensers 4 are connected to the water manifold 18 respectively. The water manifold 18 distributes water to each functional water dispenser 4, and the water inlet path of each functional water dispenser 4 is connected through the water manifold 18, which can reduce the number of pipes and pipe joints.

[0221] In one implementation, such as Figure 1 and Figure 10 As shown, when the functional water dispenser 4 is connected to the main unit 1, the two are electrically connected. This electrical connection can be used for signal transmission, for the main unit 1 to supply power to the functional water dispenser 4, or for both signal transmission and power supply. Alternatively, the functional water dispenser 4 can also be equipped with a separate external plug for power supply.

[0222] In one embodiment, the functional water machine 4 can be an ice maker, ice water machine, sparkling water machine, tea maker, tea brewer, or coffee machine, and can be selectively combined according to actual needs, offering diverse functions. For example... Figure 1 and Figure 10 As shown, the functional water dispenser 4 includes a functional water supply port 42 for automatically distributing water. Specifically, the functional water dispenser 4 also includes a water supply pump 45. Under the power provided by the water supply pump 45, the water in the functional water tank 41 flows to the functional water supply port 42 and is distributed to the user through the functional water supply port 42.

[0223] In one implementation, such as Figure 1 , Figure 10 and Figure 11 As shown, the main unit 1 also includes a first expansion function module 11, and the functional water dispenser 4 is provided with a first attachment docking module 43. The first expansion function module 11 and the first attachment docking module 43 cooperate to enable the functional water dispenser 4 to be detachably connected to the main unit 1.

[0224] Furthermore, such as Figure 1 , Figure 10 and Figure 11 As shown, the first extended function module 11 includes a first main unit water circuit connection element 111, and the first auxiliary connection module 43 includes a first auxiliary water circuit connection element 431. The water purification device 100 has at least two operating modes, specifically a multi-functional operating mode and a standalone operating mode. When the water purification device 100 is in multi-functional operating mode, a functional water dispenser 4 is installed on the first extended function module 11. The first main unit water circuit connection element 111 connects with the first auxiliary water circuit connection element 431, so that the main unit 1 supplies water to the functional water dispenser 4. The main unit 1 and the functional water dispenser 4 work together, and the functional water dispenser 4 can use the purified water provided by the main unit 1. When the water purification device 100 is in standalone operating mode, the functional water dispenser 4 is not installed on the first extended function module 11. The main unit 1 operates independently and purifies the water through the filter assembly 171 of the main unit 1 to provide purified water for drinking.

[0225] With the above setup, users can first meet their need for direct drinking purified water through the host unit 1; secondly, by connecting the first extended function module 11 to the functional water machine 4, the host unit 1 can supply water to the functional water machine 4, saving some of the structure of the functional water machine 4, resulting in good integration and low cost.

[0226] Furthermore, such as Figure 10 and Figure 11As shown, the first extended function module 11 also includes a first main electrical connection element 112, and the first auxiliary connection module 43 also includes a first auxiliary electrical connection element 432. When the water purification device 100 is in multi-functional mode, the first main electrical connection element 112 connects with the first auxiliary electrical connection element 432, and the main unit 1 supplies power to the functional water purifier 4 and / or the main unit 1 interacts with the functional water purifier 4.

[0227] In one implementation, such as Figure 10 and Figure 11 As shown, the first main water circuit connection element 111 and the first auxiliary water circuit connection element 431 constitute a water valve assembly. When the first main water circuit connection element 111 and the first auxiliary water circuit connection element 431 are in the connection state, the first main water circuit connection element 111 and the first auxiliary water circuit connection element 431 are in the open state respectively. The main unit 1 and the functional water machine 4 can achieve fluid flow through the first main water circuit connection element 111 and the first auxiliary water circuit connection element 431. When the first auxiliary water circuit connection element 431 is disconnected from the first main water circuit connection element 111, the first main water circuit connection element 111 is in the closed state to prevent water in the main unit 1 from flowing out from the first main water circuit connection element 111, and the first auxiliary water circuit connection element 431 is in the closed state to prevent water in the functional water machine 4 from flowing out from the first auxiliary water circuit connection element 431.

[0228] Furthermore, one of the first main electrical connection element 112 and the first auxiliary electrical connection element 432 is the female terminal of the coupler, and the other is the male terminal of the coupler. Circuit connection is achieved through the insertion of the female terminal and the male terminal of the coupler. Preferably, as shown... Figure 10 and Figure 11 As shown, the first main electrical connector 112 is the female end of the coupler, and the first auxiliary electrical connector 432 is the male end of the coupler, facilitating connection and avoiding the need for a complex waterproof structure for the first main electrical connector 112. Specifically, the first main electrical connector 112 includes at least one of a main power supply terminal, a main detection terminal, and a main signal terminal. The main power supply terminal provides power to the functional water dispenser 4, the main detection terminal determines whether the functional water dispenser 4 is connected, and the main signal terminal sends information to and / or receives information from the functional water dispenser 4. In actual product applications, different types and numbers of terminals are set according to product requirements. For example, to facilitate user installation, the first main electrical connector 112 includes a main power supply terminal, thus eliminating the need for an additional socket for the functional water dispenser 4 in the installation scenario. For example, to save costs and facilitate user operation through a single interface, the first main electrical connector 112 includes a main signal terminal.

[0229] In one embodiment, the first expansion function module 11 is retractably installed on the main unit 1. In standalone operating mode, the first expansion function module 11 is in a retracted state, with at least the first main unit water connection element 111 and the first main unit electrical connection element 112 located inside the main unit 1, improving the overall aesthetics. Preferably, in standalone operating mode, the first expansion function module 11 is entirely retracted within the water supply main unit 1, enhancing the overall aesthetics, preventing bumps and knocks during transport and use, and providing dust and water resistance. Figure 11 As shown, when in the multi-functional working mode, at least the first main unit water circuit connection element 111 and the first main unit electrical connection element 112 in the first extended function module 11 are located outside the main unit 1 so that the functional water purifier 4 can be smoothly connected to the first extended function module 11. Preferably, when the water purification equipment 100 is in the multi-functional working mode, at least the first main unit electrical connection element 112 and the first main unit water circuit connection element 111 in the first extended function module 11 are exposed and installed on the main unit 1 for the installation of the functional water purifier 4.

[0230] In one embodiment, the first extended function module 11 is disposed on the lower side of the host 1. The bottom of the first extended function module 11 can abut against the installation platform. After docking with the functional water machine 4, it can avoid or even not bear the weight exerted on it by the functional water machine 4, thereby ensuring that the first extended function module 11 has the characteristics of small positional deformation and high docking accuracy during long-term use.

[0231] In yet another implementation, such as Figure 11 As shown, the first expansion function module 11 is disposed on one side wall of the main unit 1, facing the functional water dispenser 4. Specifically, the first expansion function module 11 is disposed on the lower part of one side of the main unit 1, and the functional water dispenser 4 is inserted into the first main electrical connection element 112 and the first main water circuit connection element 111 in the first expansion function module 11 in the left-right direction. In this embodiment, it is worth noting that the first expansion function module 11 is fixedly disposed on the main unit 1. The protruding direction of the first main electrical connection element 112 is parallel to the connection direction of the functional water dispenser 4, and the protruding direction of the first main electrical connection element 112 is parallel to the bottom surface of the main unit 1. The extending direction of the first main water circuit connection element 111 is parallel to the bottom surface, so as to allow for lateral insertion of the functional water dispenser 4. The functional water dispenser 4 is connected to the main unit 1 in the vertical direction. The protruding direction of the first main electrical connection element 112 is perpendicular to the bottom surface of the main unit 1, and the extending direction of the first main water circuit connection element 111 is perpendicular to the bottom surface. In this way, it can avoid the following during the operation of the whole machine: Figure 14 The problem of the functional water machine 4 moving due to vibration of the second pump body 162 (typically a booster pump used to pump water out of the filter assembly 171).

[0232] In one implementation, such as Figure 11 As shown, for the storage of the first expansion function module 11, the main unit shell 12 of the main unit 1 is provided with a first accommodating cavity 122. The first accommodating cavity 122 can penetrate the side wall of the main unit shell 12 so as to facilitate the switching of the relative position of the first expansion function module 11 between the standalone working mode and the multi-functional working mode.

[0233] Furthermore, to facilitate easy switching of the relative position of the first expansion function module 11, a slide rail (not shown in the figure) is provided in the first accommodating cavity 122, and a slide groove (not shown in the figure) is provided on the first expansion function module 11. The slide rail and the slide groove cooperate with each other to allow the first expansion function module 11 to be slidably mounted on the host 1. Of course, the installation positions of the slide rail and the slide groove can be replaced, with the main purpose of facilitating installation. Alternatively, a pull-out method using a wedge block and a groove, or a pull-out method using a cylinder to push and retract, can be adopted, with the main purpose of meeting the characteristics of low cost and small installation space occupation.

[0234] In one implementation, such as Figure 12 As shown, the first extended function module 11 is retractably installed on the main unit housing 12 of the main unit 1. The main unit housing 12 also includes a first decorative cover 121. When the water purification device 100 is in standby mode, the first decorative cover 121 covers the first extended function module 11. When the first extended function module 11 is housed in the first accommodating cavity 122, due to the design requirements of the assembly space, the functional part of the first extended function module 11 is still exposed to the air. For users with high cleanliness requirements, by setting the first decorative cover 121, the functional part of the first extended function module 11 can be completely sealed after the closing action, thereby achieving a better cleanliness maintenance effect and providing users with a variety of operating needs.

[0235] In an embodiment where the first extended function module 11 is installed on the host 1 and housed in the first accommodating cavity 122, the first decorative cover 121 can be inserted into the first accommodating cavity 122 to achieve the closing action of the first extended function module 11.

[0236] In one implementation, such as Figure 11 and Figure 12 As shown, the first extended functional module 11 includes a first housing 113, a first main electrical connection element 112 (e.g., a coupler), and a first main water circuit connection element 111 (e.g., a stop valve) disposed on the first housing 113. Specifically, the functional parts of the first main electrical connection element 112 and the first main water circuit connection element 111 are both disposed on the upper surface of the first housing 113. During the docking process between the functional water machine 4 and the main unit 1, the docking action is vertically downward and fits against the side wall of the main unit 1, making the operation simple.

[0237] Furthermore, the first main electrical connection element 112 includes at least one conductive element. Even further, as... Figure 11 As shown, at least one first waterproof component 114 is provided on the first housing 113. The first waterproof component 114 is correspondingly arranged with an electrical conductive component, and at least one electrical conductive component is located below its corresponding first waterproof component 114. Preferably, the first waterproof component 114 is an openable waterproof silicone sheet. The waterproof silicone sheet has openings with cross-shaped, star-shaped, or other structures. During the docking process, the first attached electrical docking element 432 squeezes the opening of the waterproof silicone sheet, passes through, and docks with the electrical conductive component.

[0238] In one implementation, such as Figure 1 and Figure 10 As shown, the water purification device 100 also includes a kettle 2 to increase the water storage capacity of the water purification device 100. When the kettle 2 is connected to the main unit 1, the kettle 2 is connected to the water collection component 18, and purified water flows into or out of the kettle 2 through the water collection component 18. In this way, the water inlet and water outlet of the kettle 2 are integrated on the water collection component 18, further reducing the number of pipes and pipe joints required in the main unit 1.

[0239] Furthermore, when kettle 2 is connected to host 1, the two are electrically connected. This electrical connection can be used for signal transmission, for host 1 to supply power to kettle 2, or for both signal transmission and power supply. Of course, kettle 2 can also have a separate external plug for power supply.

[0240] In one embodiment, the kettle 2 includes a detachably connected kettle body 21 and kettle base 22. The kettle body 21 is not directly connected to the main unit 1, which makes it easy to quickly remove or install the kettle body 21, making it convenient to take out and operate with ease and effort. Users can remove the kettle body 21 to directly take water. In this way, users can freely and quickly take the required amount of water according to their water needs, thus enriching the functions.

[0241] In one implementation, such as Figure 1 As shown, the kettle base 22 is fixedly connected to the main unit 1 and cannot be removed, which simplifies the assembly structure of the kettle base 22 and the main unit 1 and simplifies the assembly process.

[0242] Furthermore, such as Figure 1 As shown, the main unit 1 includes a main unit base 123, and the kettle base 22 is fixed to the main unit base 123. The main unit base 123 is used to install the kettle base 22 and can also be used to form the bottom outer contour structure of the kettle base 22. The kettle base 22 does not need to be provided with an additional corresponding base plate structure, which helps to simplify the structure of the kettle base 22.

[0243] Furthermore, such as Figure 1 and Figure 10As shown, a collection component 1011 is provided between the bottom of the kettle base 22 and the main unit base 123. Raw water is supplied to the filter element assembly 171 in the main unit 1 through the collection component 1011, and wastewater generated during the purification process of the filter element assembly 171 is discharged through the collection component 1011. Specifically, the collection component 1011 is provided with a raw water inlet 10111, a raw water outlet 10112, a wastewater inlet 10113, and a wastewater outlet 10114. The collection component 1011 is provided with a first flow channel (not shown in the figure) for connecting the raw water inlet 10111 and the raw water outlet 10112, and a second flow channel (not shown in the figure) for connecting the wastewater inlet 10113 and the wastewater outlet 10114. Since the water purification equipment 100 is equipped with both a functional water machine 4 and a kettle 2, in order to avoid making the water purification equipment 100 too large, the water purification equipment 100 is not equipped with a raw water tank. The raw water inlet 10111 of the collection component 1011 is connected to the municipal tap water pipe, and the raw water outlet 10112 is connected to the inlet end of the filter element assembly 171 to supply raw water to the main unit 1. Wastewater is generated during the purification process of filter element assembly 171. The wastewater outlet of filter element assembly 171 is connected to the wastewater inlet 10113 of collection component 1011, and then discharged through wastewater outlet 10114.

[0244] In another embodiment, the kettle base 22 is detachably connected to the main unit 1. If the pipes or components in the kettle base 22 malfunction, the kettle base 22 can be removed for timely repair or replacement. The detachable connection between the kettle base 22 and the main unit 1 can also meet more user needs. For example, when the user does not want to use the kettle 2 or when there is insufficient space, the kettle base 22 and the kettle body 21 can be removed together for storage, avoiding the accumulation of dust on the kettle base 22 due to the removal of only the kettle body 21. Dirt and dirt can enter the water purification circuit of the whole machine from the joint between the kettle base 22 and the kettle body 21, causing contamination of the water purification circuit. In addition, the detachable kettle base 22 can also avoid occupying space.

[0245] In one embodiment, the connection between the kettle body 21 and the kettle base 22 includes snap-fit, fastening, or adsorption connection, which has a simple assembly structure and is easy to operate.

[0246] Furthermore, such as Figures 1 to 4 As shown, the pot body 21 is snapped downwards onto the pot base 22, allowing for a detachable connection between the pot body 21 and the pot base 22. Thus, under the weight of its own body, the pot body 21 can stably maintain this snap-fit ​​connection with the pot base 22. Of course, the snap-fit ​​direction between the pot body 21 and the pot base 22 is not limited to this; the pot body 21 can also be snapped onto the pot base 22 in a left-right or front-back direction.

[0247] Furthermore, such as Figure 2As shown, the peripheral sidewalls of the pot body 21 extend downward to form an extension wall 211; the bottom wall 212 of the pot body 21 mates with the extension wall 211 to form a groove 213. Figure 4 As shown, the kettle base 22 is provided with a snap-fit ​​protrusion 22111, and the snap-fit ​​groove 213 snaps into the snap-fit ​​protrusion 22111 to realize the assembly of the kettle body 21 and the kettle base 22. Specifically, since the kettle body 21 and the kettle base 22 need to be connected by water channels, and the kettle body 21 is snapped into the kettle base 22 downwards, the bottom of the kettle body 21 will have a structure for the water channel connection of the kettle base 22, resulting in an uneven surface of the bottom wall 212 of the kettle body. In this solution, the extension wall 211 can be used to snap into the snap-fit ​​protrusion 22111 on the one hand, and on the other hand, it can also cover the structure for the water channel connection of the kettle base 22 on the bottom of the kettle body 21, improving the appearance of the kettle body 21 after it is removed. In addition, the bottom wall of the extension wall 211 also forms a support structure so that the user can place the kettle body 21 directly on the table or other tabletop after removing it.

[0248] Furthermore, such as Figure 3 and Figure 4 As shown, the kettle base 22 is provided with an outer shell 2211, which forms the outer contour of the periphery and top of the kettle base 22, improving its aesthetics. The top wall of the outer shell 2211 is provided with a support platform 22112 and a snap-fit ​​protrusion 22111. The kettle body 21 is snapped into the outer shell 2211. At the same time, the bottom surface of the extension wall 211 abuts against the top surface of the support platform 22112, which helps the kettle base 22 to stably support the kettle body 21.

[0249] In one implementation, such as Figure 3 and Figure 4 As shown, the kettle 2 includes a detachably connected kettle body 21 and kettle base 22, and also includes a drain valve assembly 23. When the kettle body 21 is connected to the kettle base 22, the drain valve assembly 23 is in the open state, and fluid flows between the kettle body 21 and the kettle base 22 through the drain valve assembly 23. In this way, the main unit 1 can supply water to the kettle body 21 through the kettle base 22. When the kettle body 21 is detached from the kettle base 22, the drain valve assembly 23 is in the closed state to prevent water leakage from the kettle body 21 and the kettle base 22.

[0250] Specifically, such as Figure 3 As shown, the drain valve assembly 23 includes a kettle body valve assembly 231 and a kettle seat valve assembly 232. The kettle body valve assembly 231 includes a first valve body 2311 and a first valve core 2312. The kettle seat valve assembly 232 includes a second valve body 2321 and a second valve core 2322. The kettle body 21 has a first annular post 217, and the kettle seat 22 has a second annular post 227. The first valve body 2311 is installed on the first annular post 217, and the second valve body 2321 is installed on the second annular post 227. The first valve core 2312 is movably installed in the first valve body 2311, and the second valve core 2322 is movably installed in the second valve body 2321. Figure 3 Taking the specific structure shown above the second valve core 2322 as an example, when the kettle body 21 is connected to the kettle seat 22, the first valve core 2312 is located at the corresponding upper limit position, the second valve core 2322 is located at the corresponding lower limit position, and the drain valve assembly 23 is in the open state, allowing water in the kettle seat 22 to flow through the drain valve assembly 23 and enter the kettle body 21. When the kettle body 21 is detached from the kettle seat 22, the first valve core 2312 moves downward to the corresponding lower limit position, and the first valve core 2312 cooperates with the first valve body 2311 to prevent water in the kettle body 21 from flowing out from the first valve body 2311. The second valve core 2322 moves upward to the corresponding upper limit position, and the second valve core 2322 cooperates with the second valve body 2321 to prevent water in the kettle seat 22 from flowing out from the second valve body 2321. At this time, the drain valve assembly 23 is in the closed state.

[0251] In one implementation, such as Figure 8 As shown, the main unit 1 also includes a second expansion function module (not shown in the figure), and the kettle base 22 is provided with a second attachment docking module 222. The second expansion function module cooperates with the second attachment docking module 222 to allow the kettle base 22 to be detachably connected to the main unit 1.

[0252] Furthermore, such as Figure 8 As shown, the second extended function module includes a second main unit water circuit connection element, and the second auxiliary connection module 222 includes a second auxiliary water circuit connection element 2221. The water purification device 100 has at least two operating modes, specifically a multi-functional operating mode and a standalone operating mode. When the water purification device 100 is in multi-functional operating mode, a kettle 2 is installed on the second extended function module, and the second main unit water circuit connection element connects to the second auxiliary water circuit connection element 2221, so that the main unit 1 supplies water to the kettle 2. The main unit 1 and the kettle 2 work together, and the kettle 2 can use the purified water provided by the main unit 1. When the water purification device 100 is in standalone operating mode, the kettle 2 is not installed on the second extended function module, the main unit 1 operates independently, and the purified water is provided for drinking through the filter assembly 171 of the main unit 1.

[0253] With the above setup, users can first meet their need for direct drinking purified water through the main unit 1; secondly, by connecting the kettle 2 through the second expansion function module, water can be supplied to the kettle 2 based on the main unit 1, saving some of the structure of the kettle 2, resulting in good integration and low cost.

[0254] Furthermore, such as Figure 8As shown, the second extended function module also includes a second main electrical connection element, and the second attachment connection module 222 also includes a second attachment electrical connection element 2222. When the water purifier 100 is in multi-functional mode, the second main electrical connection element connects with the second attachment electrical connection element 2222, and the main unit 1 supplies power to the kettle 2 and / or the main unit 1 and the kettle 2 exchange signals.

[0255] The first extended function module 11 and the second extended function module in this solution have the same or similar structure. The first attachment docking module 43 and the second attachment docking module 222 have the same or similar structure. The structure, assembly relationship and principle of the second extended function module and the second attachment docking module 222 will be explained again, and the details are as follows.

[0256] In one implementation, such as Figure 8 As shown, the second main water circuit connection element and the second auxiliary water circuit connection element 2221 constitute a water valve assembly. When the second main water circuit connection element and the second auxiliary water circuit connection element 2221 are in the connection state, the second main water circuit connection element and the second auxiliary water circuit connection element 2221 are in the open state, and the main unit 1 and the kettle 2 can achieve fluid flow through the second main water circuit connection element and the second auxiliary water circuit connection element 2221. When the second auxiliary water circuit connection element 2221 is disconnected from the second main water circuit connection element, the second main water circuit connection element is in the closed state to prevent water in the main unit 1 from flowing out from the second main water circuit connection element, and the second auxiliary water circuit connection element 2221 is in the closed state to prevent water in the kettle 2 from flowing out from the second auxiliary water circuit connection element 2221.

[0257] Furthermore, one of the second main electrical connection element and the second auxiliary electrical connection element 2222 is a female coupler terminal, and the other is a male coupler terminal. Circuit connection is achieved through the insertion of the female coupler terminal and the male coupler terminal. Preferably, as shown... Figure 8 As shown, the second main electrical connector is the female terminal of the coupler, and the second auxiliary electrical connector 2222 is the male terminal of the coupler, facilitating connection and avoiding the need for a complex waterproof structure for the second main electrical connector. Specifically, the second main electrical connector includes at least one of a main power supply terminal, a main detection terminal, and a main signal terminal. The main power supply terminal provides power to the kettle, the main detection terminal determines whether the kettle is connected, and the main signal terminal sends information to and / or receives information from the kettle. In actual product applications, different types and numbers of terminals are set according to product requirements. For example, to facilitate user installation, the second main electrical connector includes a main power supply terminal, thus eliminating the need for an additional socket for the kettle in the installation scenario. For example, to save costs and facilitate user operation through a single interface, the second main electrical connector includes a main signal terminal.

[0258] In one embodiment, the second expansion function module is retractably installed on the main unit 1. In standalone operation mode, the second expansion function module is retracted, with at least the second main unit water circuit connection element and the second main unit electrical connection element located inside the main unit 1 to improve the overall aesthetics. Preferably, in standalone operation mode, the entire second expansion function module is retracted inside the water supply main unit 1, enhancing the overall aesthetics and preventing damage during transport and use. It also provides dust and water protection. In multi-functional operation mode, at least the second main unit water circuit connection element and the second main unit electrical connection element are located outside the main unit 1, allowing the kettle 2 to connect smoothly to the second expansion function module. Preferably, when the water purification device 100 is in multi-functional operation mode, at least the second main unit electrical connection element and the second main unit water circuit connection element are exposed on the main unit 1 for installing the kettle 2.

[0259] In one embodiment, the second expansion module is located on the lower side of the main unit 1. The bottom of the second expansion module can abut against the mounting platform. After connecting the kettle 2, it can minimize or even eliminate the weight exerted on it by the kettle 2, thereby ensuring that the second expansion module has minimal positional deformation and high connection accuracy during long-term use. Specifically, the functional water dispenser 1 and the kettle 2 are respectively located on the left and right sides of the main unit 1 for user convenience.

[0260] In another embodiment, the second expansion module is disposed on one side wall of the main unit 1, facing the kettle 2. Specifically, the second expansion module is disposed on the lower part of one side of the main unit 1, and the kettle 2 is inserted into the second main electrical connection element and the second main water circuit connection element of the second expansion module in the left-right direction. In this embodiment, it is worth noting that the second expansion module is fixedly disposed on the main unit 1. The protruding direction of the second main electrical connection element is parallel to the docking direction of the kettle 2, and the protruding direction of the second main electrical connection element is parallel to the bottom surface of the main unit 1. The extending direction of the second main water circuit connection element is parallel to the bottom surface, so as to allow for lateral insertion of the kettle 2. The kettle 2 is docked with the main unit 1 in the vertical direction. The protruding direction of the second main electrical connection element is perpendicular to the bottom surface of the main unit 1, and the extending direction of the second main water circuit connection element is perpendicular to the bottom surface. In this way, it can be avoided that during the operation of the whole machine, such as Figure 14 The problem of the kettle 2 moving due to vibration of the second pump body 162 (typically a booster pump used to pump water out of the filter assembly 171).

[0261] In one embodiment, for the storage of the second extended function module, the main unit 1 has a second accommodating cavity (not shown in the figure) on the main unit housing 12. The second accommodating cavity can penetrate the side wall of the main unit housing 12 so as to facilitate the switching of the relative position of the second extended function module between the standalone working mode and the multi-functional working mode.

[0262] Furthermore, to facilitate easy switching of the relative position of the second expansion module, a slide rail (not shown in the figure) is provided in the second accommodating cavity, and a slide groove (not shown in the figure) is provided on the second expansion module. The slide rail and slide groove cooperate with each other to allow the second expansion module to be slidably mounted on the main unit 1. Of course, the installation positions of the slide rail and slide groove can be replaced, with the main purpose of facilitating installation. Alternatively, a pull-out method using a wedge block and groove, or a pull-out method using a cylinder to push and retract, can be adopted, with the main purpose of meeting the characteristics of low cost and small installation space occupation.

[0263] In one embodiment, the second extended functional module is retractably mounted on the main unit housing 12 of the main unit 1. The main unit housing 12 also includes a second decorative cover (not shown in the figure). When the water purification device 100 is in standby mode, the second decorative cover closes on the second extended functional module. When the second extended functional module is housed in the second accommodating cavity, due to the design requirements of the assembly space, the functional part of the second extended functional module is still exposed to the air. For users with high cleanliness requirements, by providing the second decorative cover, the functional part of the second extended functional module can be completely sealed after closing, thereby achieving a better cleanliness maintenance effect and providing users with a variety of operational needs.

[0264] In an embodiment where the second extended function module is installed on the host 1 and housed in the second accommodating cavity, the second decorative cover can be inserted into the second accommodating cavity to achieve the closing action of the second extended function module.

[0265] In one embodiment, the second extended functional module includes a second housing, on which a second main electrical connection element (such as a coupler) and a second main water connection element (such as a stop valve) are disposed. Specifically, the functional parts of the second main electrical connection element and the second main water connection element are both disposed on the upper surface of the second housing. During the docking process between the kettle 2 and the main unit 1, the docking action is vertically downward and conforms to the side wall of the main unit 1, making the operation simple.

[0266] Furthermore, the second main electrical docking element includes at least one conductive element. Even further, the second housing is provided with at least one second waterproof element, which is correspondingly disposed to the conductive element, with the at least one conductive element located below its corresponding second waterproof element. Preferably, the second waterproof element is an openable waterproof silicone sheet. The waterproof silicone sheet has openings in a cross-shaped, star-shaped, or other structure. During the docking process, the second attached electrical docking element 2222 squeezes through the openings of the waterproof silicone sheet, passes through, and docks with the conductive element.

[0267] In one implementation, such as Figure 10 As shown, the main unit 1 also includes a water purification tank 13, and the second main unit water circuit connection element is in fluid communication with the water purification tank 13 so that the kettle body 21 is connected to the water purification tank 13.

[0268] In one implementation, such as Figure 4 As shown, the kettle stand 22 includes a base 2212 and a bracket 2213. The bracket 2213 is installed above the base 2212. The base 2212 and the bracket 2213 can be connected by fasteners (such as screws) or by snap-fit ​​connection. The second attachment docking module 222 is installed on the base 2212, and the kettle stand valve assembly 232 of the drain valve assembly 23 is installed on the bracket 2213. The kettle stand 22 is designed as a split structure, which facilitates processing.

[0269] Furthermore, such as Figure 4 , Figure 5 and Figure 8 As shown, a receiving space 2214 is formed between the upper surface of the base 2212 and the lower surface of the support 2213. The kettle base 22 also includes an adapter 223 and a kettle control board 224, with the adapter 223 housed within the receiving space 2214. The output terminal of the second attached electrical connection element 2222 is located in the receiving space 2214 and electrically connected to the input terminal of the adapter 223. The output terminal of the adapter 223 is electrically connected to the kettle control board 224. The adapter 223 is used to convert AC power to DC power to supply power to the kettle control board 224. In addition, the main control board in the host 1 outputs a signal line to the second host electrical connection element, while the second attached electrical connection element 2222 outputs a signal line to the kettle control board 224, enabling signal interaction between the host 1 and the kettle 2.

[0270] Furthermore, such as Figure 5 and Figure 6As shown, the upper surface of the base 2212 is provided with a first groove 22121, and the adapter 223 is at least partially engaged in the first groove 22121. Thus, when assembling the kettle 2, the adapter 223 is first engaged in the first groove 22121, and then further connection is made (for example, by fixing with screws). In this solution, the setting of the first groove 22121 can, on the one hand, play a positioning role in the installation position of the adapter 223, and on the other hand, can initially restrict the movement of the adapter 223, which facilitates assembly.

[0271] In one implementation, such as Figures 8 to 9 As shown, the lower surface of the base 2212 is recessed towards the bracket 2213 to form a recess 22122. The input end of the second attachment docking module 222 is located in the recess 22122. When the kettle base 22 is installed on the main unit 1, the second expansion function module is inserted into the recess 22122 so that the second expansion function module cooperates with the second attachment docking module 222. In this design, the recess 22122 is provided to accommodate the input end of the second attachment docking module 222, preventing the second attachment docking module 222 from protruding from the outside of the base 2212. This avoids the kettle base 22 being inconvenient to place after removal and provides protection for the second attachment docking module 222 during transportation or use, preventing the second attachment docking module 222 from being damaged.

[0272] Furthermore, such as Figure 8 As shown, the bottom of the recess 22122 and its side facing the host 1 are both open. The second expansion module is inserted into the recess 22122 from bottom to top. This allows for stable docking between the second attachment module 222 and the second expansion module under the weight of the kettle 2 itself. When the kettle base 22 is disassembled, it moves upward to detach from the host 1. Specifically, since the water purifier 100 has a certain height, the application scenario of the water purifier 100 has sufficient vertical space. In this solution, the kettle base 22 is installed and removed vertically, making full use of the existing vertical space in the application scenario, which can be applied to application scenarios with limited horizontal space. Of course, the kettle base 22 can also be installed and removed from the host 1 horizontally or backward, suitable for application scenarios with sufficient horizontal space.

[0273] In one implementation, such as Figure 5 and Figure 6As shown, the lower surface of the base 2212 is recessed to form a recessed portion 22122, while a protrusion 22123 is formed on the upper surface of the base 2212. The adapter 223 is located on one side of the protrusion 22123. Further, one side wall of the protrusion 22123 forms one side wall of the first groove 22121. The adapter 223 abuts against one side wall of the protrusion 22123, resulting in a compact arrangement that facilitates the miniaturization of the base 2212. The kettle base 22 is also equipped with a first power cord (not shown in the figure), which is used to electrically connect the output end of the second attached electrical connection element 2222 to the input end of the adapter 223. The base 2212 is also provided with a first wire hole 22124, which is used to pass the first power cord through, facilitating neat wiring. Preferably, at least one side of the first wire hole 22124 is open to facilitate wire passing.

[0274] Furthermore, such as Figure 5 and Figure 6 As shown, the first wire hole 22124 is located on the upper surface of the protrusion 22123. Specifically, the adapter 223 is located on one side of the protrusion 22123, the output end of the second attached electrical connection element 2222 is located above the protrusion 22123, and the first wire hole 22124 is located between the adapter 223 and the output end of the second attached electrical connection element 2222, which helps to shorten the length of the first power cord.

[0275] In one implementation, such as Figure 8 As shown, a second groove 22131 is provided on one outer wall of the bracket 2213. The kettle control board 224 is installed in the second groove 22131. The second groove 22131 also protects the kettle control board 224 from scratches. The kettle control board 224 is positioned opposite the output end of the adapter 223 to shorten the distance between them. The kettle base 22 is also equipped with a second power cord (not shown in the figure), which is used to electrically connect the output end of the adapter 223 to the kettle control board 224. The groove wall of the second groove 22131 is provided with a second wire hole 221311, which is used to pass the second power cord through for neat wiring. Preferably, at least one side of the second wire hole 221311 is open to facilitate wire passing.

[0276] Furthermore, such as Figure 5 and Figure 8 As shown, in order to facilitate the connection of the first power cord and the second power cord, the first wire hole 22124 is located on one side of the adapter 223, and the second wire hole 221311 is located on the other side of the adapter 223, so as to avoid interference between the first power cord and the second power cord.

[0277] In one implementation, such as Figure 5and Figure 7 As shown, the water purification device 100 also includes a locking element 31, which can move between a locked position and an unlocked position. When the locking element 31 is in the locked position, it locks the kettle base 22 to prevent it from detaching from the main unit 1. When the locking element 31 moves to the unlocked position, it releases the lock, allowing the kettle base 22 to detach from the main unit 1. Specifically, in normal use, the kettle base 22 does not need to be removed, and the kettle body 21 can be removed as needed to access drinking water. Since the kettle body 21 exerts a force on the kettle base 22 during installation and removal, the locking element 31 is provided to lock the kettle base 22 and ensure a stable connection between the kettle base 22 and the main unit 1 to prevent the kettle base 22 from detaching from the main unit 1 due to the force exerted by the kettle body 21.

[0278] Furthermore, such as Figure 5 As shown, the water purification device 100 also includes an elastic element 32, which is used to hold the locking element 31 in the locked position. When the external force applied to the locking element 31 is greater than the elastic force of the elastic element 32, the locking element 31 can move towards the unlocked position under the external force, and the elastic element 32 is compressed, thus storing energy. When the external force is removed, the elastic element 32 rebounds, releases energy, and applies a pushing force to the locking element 31 to reset the locking element 31 to the locked position. When the locking element 31 is in the locked position, the elastic element 32 applies a force to the locking element 31, so that the locking element 31 can be stably in the locked position. Preferably, the elastic element 32 is a spring, which has a simple structure.

[0279] In one implementation, such as Figure 5 As shown, the locking element 31 is movably mounted on the kettle base 22. When the kettle base 22 is connected to the main unit 1 and the locking element 31 is in the locked position, the main unit 1 at least partially blocks the path of the locking element 31 moving along the first direction. The main unit 1 can prevent the locking element 31, together with the kettle base 22, from moving along the first direction and disengaging from the main unit 1, thus achieving locking; wherein, the first direction is the direction of movement of the kettle base 22 when it disengages from the main unit 1. In a specific embodiment, the kettle base 22 moves upward to disengage from the main unit 1, the first direction being upward, and the kettle body 21 is also lifted upward to be removed. By providing the locking element 31, it is possible to prevent the kettle base 22 from being lifted up when the kettle body 21 is lifted upward.

[0280] Furthermore, such as Figure 9 As shown, when the kettle base 22 is connected to the main unit 1 and the locking element 31 is in the locked position, the locking element 31 abuts against the main unit 1 in the first direction. The main unit 1 restricts the locking element 31, so that the kettle base 22 cannot move in the first direction.

[0281] Furthermore, such as Figure 9As shown, when the kettle base 22 is connected to the main unit 1 and the locking element 31 is in the locked position, the locking element 31 abuts against the second expansion function module along the first direction. Specifically, the main unit 1 connects to the kettle 2 through the exposed second expansion function module, and the locking element 31 can directly abut against the second expansion function module to achieve locking. This eliminates the need for additional components on the main unit 1 to abut against the locking element 31, reducing modifications to the main unit 1 structure and lowering costs. Of course, the cooperation between the locking element 31 and the main unit 1 is not limited to this. For example, a locking groove (not shown in the figure) can be provided on the main unit 1, and the locking element 31 can be inserted into the locking groove to achieve locking.

[0282] Furthermore, such as Figure 9 As shown, when the kettle base 22 is connected to the main unit 1 and the locking element 31 is in the locked position, the locking element 31 extends at least partially into the recess 22122 and abuts against the second expansion function module along the first direction. In one specific embodiment, the kettle 2 is located on the right side of the main unit 1. When the kettle base 22 is connected to the main unit 1, the locking element 31 moves to the right to the unlocked position, and then the second attachment docking module 222 is aligned downwards with the second expansion function module and docked. The locking element 31 in the unlocked position will not interfere with the second expansion function module being inserted into the recess 22122. After docking, the locking element 31 is released, and under the elastic force of the elastic element 32, the locking element 31 moves to the left to the locked position. The locking element 31 abuts against the second expansion function module along the first direction (upward direction) to prevent the kettle base 22 from moving upward, thereby achieving locking. In this design, the recessed portion 22122 provides a space for the locking element 31 to move. The arrangement is ingenious and does not require additional space for the locking element 31, which is beneficial for the miniaturization design of the kettle seat 22.

[0283] Furthermore, such as Figure 5 , Figure 6 , Figure 7 and Figure 9 As shown, the locking element 31 includes a locking part 311 and a connecting block 312 connected together; the kettle base 22 includes a base 2212, the base 2212 is provided with a third groove 22129, the connecting block 312 is movably installed in the third groove 22129, and the third groove 22129 and the recessed part 22122 are connected through a first through hole 22125. When the locking element 31 is in the locked position, the locking part 311 passes through the first through hole 22125 to abut against the second extended functional module along the first direction. In this solution, the locking element 31 has a simple structure, is easy to assemble, and requires minimal modification to the structure of the kettle base 22.

[0284] Furthermore, such as Figure 7 and Figure 9As shown, under the elastic force of the elastic element 32, the locking element 31 on the removed kettle seat 22 remains in the locked position. The locking part 311 is provided with a guide slope 3111. When assembling the kettle seat 22 with the second expansion function module of the main unit 1, the guide slope 3111 contacts and cooperates with the outer wall of the main unit to drive the locking element 31 to move to the unlocked position. The kettle seat 22 moves downward until the guide slope 3111 of the locking part 311 contacts the second expansion function module. As the kettle seat 22 continues to move downward, the guide slope 3111 is subjected to the reaction force of the second expansion function module, causing the locking part 311 to move to the unlocked position. No manual operation of the locking element 31 is required, which facilitates assembly. In addition, a groove (not shown) can be correspondingly provided on the second expansion function module. When the kettle seat 22 continues to move downward until it is in place with the second expansion function module, the locking part 311 moves from the unlocked position to the locked position. The entire process does not require manual operation of the locking element 31, which facilitates assembly.

[0285] Furthermore, such as Figure 6 , Figure 7 and Figure 9 As shown, the wall of the first through hole 22125 is clearance-fitted with the circumferential outer contour of the locking part 311. The wall of the first through hole 22125 also guides the locking element 31 to move between the locked position and the unlocked position, thereby restricting the locking element 31 from moving in other directions and disengaging from the locked or unlocked position. In one specific embodiment, the locking element 31 moves along the front-back direction of the water purification device 100 to switch between the locked position and the unlocked position, and the wall of the first through hole 22125 can restrict the locking element 31 from moving in the left-right and up-down directions.

[0286] Furthermore, such as Figures 5 to 7 As shown, the locking part 311 is provided with a limiting elongated hole 3121, and the base 2212 is provided with a limiting post 22126. The limiting post 22126 is inserted into the limiting elongated hole 3121, and the limiting elongated hole 3121 can be displaced relative to the limiting post 22126 along its own length direction. The limiting post 22126 cooperates with the limiting elongated hole 3121 to guide the locking element 31 to move between the locked position and the unlocked position, so as to further restrict the locking element 31 from moving in other directions and disengaging from the locked position or the unlocked position, ensuring that the locking element 31 can accurately switch between the locked position and the unlocked position.

[0287] Furthermore, such as Figure 5 and Figure 6As shown, the kettle base 22 also includes a bolt 225, which is screwed into the threaded hole of the limiting post 22126. The nut of the bolt 225 abuts against the locking element 31 along its own axial direction to press the locking element 31 against the groove wall of the third groove 22129. Specifically, the locking element 31 also includes a mounting post 314. The mounting post 314, the connecting block 312, and the locking part 311 are connected in sequence in the direction toward the recess 22122. One end of the elastic element 32 is connected to the base 2212, and the other end is sleeved on the mounting post 314. The locking part 311 is movably inserted into the first through hole 22125 of the base 2212. The nut of the bolt 225 abuts against the connecting block 312 of the locking element 31, thereby completing the assembly of the locking element 31. The assembly requires fewer parts, is easy to assemble, and controls costs. Of course, in order to reduce the friction between the locking element 31 and the nut of the bolt 225 when the locking element 31 moves, a washer (not shown in the figure) is also provided between the nut of the bolt 225 and the locking element 31.

[0288] In one implementation, such as Figures 6 to 8 As shown, the locking element 31 also includes a pushing part 313, which is connected to the connecting block 312. The base 2212 has a second through hole 22127, through which the pushing part 313 passes and extends to the outside of the kettle seat 22. When unlocking is required, external force pushes the pushing part 313 to move the locking element 31 to the unlocked position. The pushing part 313 is used for user operation, making it easy for the user to unlock the kettle seat 22.

[0289] Furthermore, such as Figure 6 and Figure 8 As shown, the second through hole 22127 is provided on the bottom wall of the base 2212, and the pushing part 313 extends partially to the lower surface of the base 2212. Specifically, the kettle base 22 usually does not need to be removed, that is, the kettle base 22 is usually kept in a state of constant connection with the main unit 1. By setting the pushing part 313 at the bottom of the base 2212, it is possible to prevent the kettle 2 from being unlocked due to accidental contact with the pushing part 313 when it is in normal use.

[0290] Furthermore, such as Figure 8 As shown, four legs 22128 are provided on the lower surface of the base 2212. The four legs 22128 are located at the four corners of the lower surface of the base 2212 to support the kettle seat 22. The lower surface of the pushing part 313 is not lower than the lower surface of the legs 22128 to prevent the pushing part 313 from deforming due to prolonged pressure from the placement surface, thereby affecting the locking function. Of course, the number of legs 22128 is not limited to four; it can also be one (e.g., a leg in the shape of a square ring), two (e.g., two long strip legs 22128), three, or even more.

[0291] In one implementation, such as Figure 3 and Figure 4 As shown, the kettle 2 also includes an in-situ detection component 24, which is used to detect whether the kettle body 21 is installed in place.

[0292] Furthermore, the in-situ detection component 24 includes an in-situ detection reed switch 241 and an in-situ detection magnet 242. The in-situ detection reed switch 241 is mounted on the kettle base 22, and the in-situ detection magnet 242 is mounted on the kettle body 21. The in-situ detection magnet 242 cooperates with the in-situ detection reed switch 241 to detect whether the kettle body 21 is installed correctly. Specifically, when the kettle body 21 is installed correctly, the magnetic field of the in-situ detection magnet 242 can cause the reed of the in-situ detection reed switch 241 to close, and the circuit of the in-situ detection reed switch 241 is turned on. When the kettle body 21 is not installed correctly, the magnetic field of the in-situ detection magnet 242 is far from the in-situ detection reed switch 241, the reed of the in-situ detection reed switch 241 is open, and the circuit of the in-situ detection reed switch 241 is turned off. In this way, by obtaining the on / off status of the circuit of the in-situ detection reed switch 241, it is determined whether the kettle body 21 is installed correctly.

[0293] In one implementation, such as Figure 2 and Figure 3 As shown, the kettle base 22 is also equipped with a sterilization lamp assembly 226, and the kettle body 21 is equipped with a light-transmitting structure 214. The sterilization light emitted by the sterilization lamp assembly 226 enters the kettle cavity 215 of the kettle body 21 through the light-transmitting structure 214 to sterilize the water in the kettle body 21 and ensure safe drinking.

[0294] Furthermore, such as Figure 3 and Figure 4 As shown, the sterilization lamp assembly 226 includes a sterilization lamp 2261 and a lamp cover 2262. The sterilization lamp 2261 is installed in the lamp cover 2262, and the lamp cover 2262 is installed on the pot base 22. The sterilization lamp 2261 is installed through the lamp cover 2262, and the lamp cover 2262 can also protect and prevent dust from the sterilization lamp 2261.

[0295] Furthermore, such as Figure 3 As shown, the end of the lampshade 2262 facing the light-transmitting structure 214 is hemispherical, which helps the light emitted by the sterilization lamp 2261 to enter the pot body 21 more evenly.

[0296] Furthermore, such as Figure 3 As shown, the light-transmitting structure 214 is in the shape of a cover, and the sterilization lamp 2261 is at least partially located in the light-transmitting structure 214, which further improves the uniformity of the sterilization light distribution entering the pot body 21 and improves the sterilization efficiency.

[0297] In one implementation, such as Figure 3As shown, the light-transmitting structure 214 extends at least partially into the pot cavity 215, and the end of the light-transmitting structure 214 extending into the pot cavity 215 is hemispherical to improve the uniformity of the sterilization light distribution entering the pot body 21.

[0298] In one implementation, such as Figure 1 , Figure 4 and Figure 9 As shown, the outer casing 2211 covers the outer periphery of the bracket 2213. The outer casing 2211 has a third through hole 22113 and a fourth through hole 22114. The third through hole 22113 allows fluid flow between the kettle body 21 and the kettle base 22 through the drain valve assembly 23. The fourth through hole 22114 allows the sterilization lamp assembly 226 mounted on the bracket 2213 to emit sterilization light towards the kettle body 21. By covering the outline of the bracket 2213 and the components mounted on the bracket 2213 with the outer casing 2211, the aesthetic appearance of the kettle base 22 is ensured.

[0299] In one implementation, such as Figure 9 and Figure 13 As shown, the main unit 1 also includes a clean water tank 13 and a main unit water supply port 14, and the kettle base 22 includes a first low water level detection mechanism 251 and a water storage chamber 252. Figure 3 As shown, when the kettle body 21 is installed on the kettle base 22, the kettle body 21 and the water storage chamber 252 are interconnected. In a specific embodiment, the kettle body 21 and the kettle base 22 achieve fluid flow through the drain valve assembly 23. When the kettle body 21 is installed on the kettle base 22, the drain valve assembly 23 is in the open state, and the kettle body 21 and the water storage chamber 252 are interconnected.

[0300] like Figure 10 and Figure 13 As shown, the lowest point of the water storage chamber 252 is located below the lowest point of the kettle body 21's kettle cavity 215. The first low water level detection mechanism 251 is used to obtain low water level information in the water storage chamber 252 to determine whether the water level in the kettle body 21 has reached the preset low water level. When the kettle body 21 is installed on the kettle base 22, the water purification device 100 has a first working mode. At this time, the kettle cavity 215 and the purified water tank 13 are in communication. When the water purification device 100 turns on the water supply, the purified water tank 13 and the kettle body 21 supply water to the main unit's water supply port 14 respectively and simultaneously. The water in the kettle body 21 flows to the main unit's water supply port 14 through the water storage chamber 252. Of course, the water purification device 100 can also have a second working mode, in which the kettle cavity 215 and the purified water tank 13 are not in communication.

[0301] In the above technical solution, when the water purifier 100 is turned on to supply water, the water in the kettle body 21 flows through the water storage chamber 252 to the main unit water supply port 14 of the main unit 1. Furthermore, the lowest point of the water storage chamber 252 is located below the lowest point of the kettle cavity 215 of the kettle body 21, which helps to drain the water in the kettle cavity 215 as much as possible. In addition, when the kettle body 21 is installed on the kettle base 22 and the water purifier 100 is in the first working mode, the kettle body 21 and the purified water tank 13 are connected. When the water in both the kettle body 21 and the purified water tank 13 is in a static state and has not reached the corresponding low water level, the water levels in both the kettle body 21 and the purified water tank 13 are equal. Thus, the water level detection mechanism configured in the main unit 1 of the water purifier 100 can simultaneously detect the water levels in both the kettle body 21 and the purified water tank 13. However, when the water in the kettle body 21 and the purified water tank 13 are in a static state, the water levels in both are equal. During the process of water supply to both the kettle and the water tank 13 simultaneously, if, for some reason (for example, the cross-sectional area of ​​the kettle body 21 is larger than the cross-sectional area of ​​the water tank 13 on the same horizontal plane), the water level in the kettle body 21 drops more slowly than that in the water tank 13, the water purification equipment 100 of this solution is equipped with a first low water level detection mechanism 251 to detect the low water level information in the water storage chamber 252, so as to ensure that the water in the kettle body 21 can be used up to the preset low water level of the kettle body 21, reduce stagnant water, and ensure healthy drinking water.

[0302] In one implementation, such as Figure 3 As shown, the water storage cavity 252 is located below the kettle cavity 215, which is conducive to draining the water in the kettle cavity 215.

[0303] In one implementation, such as Figure 3 As shown, the bottom of the pot cavity 215 is connected to the water storage cavity 252. All the water in the pot cavity 215 can be supplied to the outside through the water storage cavity 252. That is, all the water in the pot cavity 215 can be drained, leaving no stagnant water.

[0304] Furthermore, such as Figure 3 As shown, the bottom of the kettle cavity 215 is connected to the top of the water storage cavity 252. Specifically, as... Figure 10 As shown, the water purification device 100 is equipped with a first pump body 161. Under the water power provided by the first pump body 161, the purified water tank 13 and the kettle body 21 supply water to the main unit water supply port 14 simultaneously. In this design, the bottom of the kettle cavity 215 is connected to the top of the water storage cavity 252, which facilitates the rapid entry of water from the kettle cavity 215 into the water storage cavity 252, thereby increasing the water supply speed.

[0305] In one implementation, such as Figure 3 As shown, when the water purification device 100 is in the first working mode, the kettle chamber 215 is connected to the water purification tank 13 through the water storage chamber 252. There is no need to set up an additional connecting pipe on the water purification tank 13 to connect to the water purification tank 13, which simplifies the structure and makes the layout more reasonable.

[0306] Furthermore, such as Figure 9 and Figure 10 As shown, when the kettle body 21 is installed on the kettle base 22, the bottom of the water storage cavity 252 is connected to the water circuit of the main unit 1, which helps to drain the water in the water storage cavity 252 as much as possible and reduce the residual stale water in the water storage cavity 252.

[0307] Furthermore, such as Figure 9 As shown, the kettle base 22 includes a water storage box 25, and a water storage cavity 252 is formed inside the water storage box 25. The first low water level detection mechanism 251 includes a cooperating first float 2511 and a first liquid level sensor 2512. The first float 2511 is located in the water storage cavity 252, and the first liquid level sensor 2512 is installed on the outer wall of the water storage box 25.

[0308] Furthermore, such as Figure 9 As shown, the volume of the water storage chamber 252 is greater than or equal to three times the volume of the first float 2511. In this way, the water in the water storage chamber 252 above the low water level can provide sufficient buoyancy for the first float 2511, preventing the suction force of the first pump body 161 from directly sucking the first float 2511 to the bottom of the water storage box 25, which would cause the first low water level detection mechanism 251 to misjudge that the kettle body 21 is short of water.

[0309] In one implementation, such as Figure 4 and Figure 9 As shown, the water storage box 25 is disposed in the accommodating space 2214 formed between the bracket 2213 and the base 2212. The water storage box 25 is located above the adapter 223 and the second attachment docking module 222. The components are arranged compactly, and the space utilization rate is high.

[0310] In one implementation, such as Figure 9 As shown, the first liquid level sensor 2512 is installed on the top wall of the water storage box 25. When the water level in the water storage chamber 252 is within a preset water level range, the first float 2511 is in a preset high position range, so that the circuit of the first liquid level sensor 2512 is turned on. When the water level in the water storage chamber 252 drops to a preset low water level, the first float 2511 moves down to the preset low water level, so that the circuit of the first liquid level sensor 2512 is turned off, thereby determining that the water level in the vessel 21 has reached the preset low water level. Of course, the first liquid level sensor 2512 can also be installed on the side wall of the water storage box 25. In this way, when the first float 2511 is in a preset high position range, the circuit of the first liquid level sensor 2512 is turned off, and when the first float 2511 moves down to the preset low water level, the circuit of the first liquid level sensor 2512 is turned on.

[0311] Furthermore, such as Figure 9 As shown, a hollow column 2531 is provided inside the water storage box 25, and the first float 2511 is movably installed in the hollow column 2531.

[0312] Furthermore, such as Figure 9 As shown, the inner wall of the hollow column 2531 is provided with multiple abutment ribs 25311; all the abutment ribs 25311 are spaced apart along the circumference of the first float 2511, and the abutment ribs 25311 are used to guide the movement direction of the first float 2511. In this scheme, the abutment ribs 25311 replace the circumferential inner wall of the hollow column 2531 to guide the movement of the first float 2511, which not only plays a guiding role, but also ensures that the frictional force generated when the abutment ribs 25311 collide with the first float 2511 is low, so as not to affect the water level detection results.

[0313] Furthermore, such as Figure 9 As shown, the cross-section of the hollow column 2531 is an open annular shape. The opening of the hollow column 2531 is designed to ensure that the first float 2511 can contact the water in the water storage cavity 252.

[0314] Furthermore, such as Figure 3 and Figure 9 As shown, the water storage box 25 includes a box body 253 and a cover 254, which are sealed together to form a water storage cavity 252. A hollow column 2531 is disposed in the box body 253, with one axial end of the hollow column 2531 being open and facing the cover 254. When assembling the first float 2511, the first float 2511 is inserted downward into the hollow column 2531, and then the cover 254 is connected to the box body 253, making assembly quick and easy.

[0315] In one implementation, such as Figure 9 As shown, the bottom of the water storage box 25 is provided with a box body connection port 255. When the kettle base 22 is connected to the main unit 1, the box body connection port 255 is connected to the water circuit of the main unit 1 through the second attached water circuit docking element 2221.

[0316] Furthermore, such as Figure 3 and Figure 9 As shown, a guide structure 2532 is provided inside the water storage box 25. The guide structure 2532 is suspended above the box body connection port 255 and has a guide channel 25321. The second attached water circuit docking element 2221 includes an attached water circuit valve core 22211. One end of the attached water circuit valve core 22211 is movably inserted into the guide channel 25321, which guides the attached water circuit valve core 22211 to move between an open position and a closed position. When the attached water circuit valve core 22211 is in the open position, the box body connection port 255 is connected to the water circuit of the main unit 1; when the attached water circuit valve core 22211 is in the closed position, the box body connection port 255 is blocked by fluid. In this solution, the guide structure 2532 is equivalent to a valve body structure and works in conjunction with the attached water circuit valve core 22211, which simplifies the structure of the second attached water circuit docking element 2221.

[0317] In one embodiment, the capacity of the kettle body 21 is greater than that of the water tank 13, providing a large water storage capacity for the user. The lowest point of the kettle cavity 215 is not higher than the lowest point of the water storage cavity 131 of the water tank 13. Typically, the main unit 1 has many components, which limits the height of the water tank 13. Furthermore, to ensure the stability of the main unit 1's center of gravity, the water tank 13 is usually located at the top of the main unit 1. The height of the kettle body 21 is only affected by the kettle base 22. By extending the height of the kettle body 21 as much as possible, the capacity of the kettle body 21 is increased. Thus, the lowest point of the kettle cavity 215 is lower than or level with the lowest point of the water storage cavity 131. When the kettle 2 is connected to the main unit 1 and the water purifier 100 is in the first working mode, the first low water level detection mechanism 251 obtains the low water level information in the water storage chamber 252 to determine that the kettle body 21 and the water purification tank 13 have reached the corresponding preset low water level. That is, at this time, the first low water level detection mechanism 251 acts as the low water level detection mechanism of the whole machine and uses the low water level information of the kettle body 21 as the low water level judgment standard of the whole machine. This is conducive to draining the water in the kettle chamber 215 as much as possible and avoiding misjudging that the kettle chamber 215 is short of water because the low water level information of the water purification tank 13 is used as the low water level judgment standard of the whole machine.

[0318] Furthermore, such as Figure 3 and Figure 10 As shown, the lowest point of the kettle cavity 215 is located below the lowest point of the purified water storage cavity 131 to increase the capacity of the kettle cavity 215.

[0319] In one embodiment, the main unit 1 further includes a second low water level detection mechanism. When the kettle 2 is not connected to the main unit 1, the second low water level detection mechanism is used to obtain low water level information in the purified water storage chamber 131 so as to replenish water in time when the purified water tank 13 is short of water.

[0320] Furthermore, such as Figure 13 and Figure 17As shown, the main unit 1 also includes a low water level detection box 151, which includes a cavity 1512 communicating with the purified water storage chamber 131. The lowest point of the cavity 1512 is located below the lowest point of the purified water storage chamber 131. A second low water level detection mechanism is disposed on the low water level detection box 151. When the water purification device 100 turns on to supply water, the water in the purified water storage chamber 131 flows through the cavity 1512 to the main unit's water supply port 14, which helps to drain the water in the purified water storage chamber 131 as much as possible. In one specific embodiment, when the kettle 2 is connected to the host 1 and the water purification device 100 is in the first working mode, the lowest point of the kettle cavity 215 is located below the lowest point of the purified water storage cavity 131. If water in the purified water tank 13 is taken until the water level drops to the container cavity 1512, there is still water in the kettle cavity 215. Since the cross-sectional area of ​​the kettle cavity 215 is larger than the cross-sectional area of ​​the container cavity 1512, the water level in the kettle cavity 215 drops at a lower rate than the water level in the container cavity 1512. In order to avoid misjudging that there is no water in the kettle cavity 215, the first low water level detection mechanism 251 is used as the low water level detection mechanism of the whole machine.

[0321] Furthermore, such as Figure 13 As shown, the cavity 1512 is located below the purified water storage cavity 131, which is beneficial for draining the water in the purified water storage cavity 131.

[0322] Furthermore, such as Figure 3 and Figure 10 As shown, the water storage chamber 252 is located below the kettle chamber 215, and the lowest point of the water storage chamber 252 is located below the lowest point of the purified water storage chamber 131. Thus, when the kettle 2 is connected to the host 1 and the water purification device 100 is in the first working mode, the first low water level detection mechanism 251 can obtain the low water level information in the water storage chamber 252 to determine whether the kettle body 21 and the purified water tank 13 have reached the corresponding preset low water level.

[0323] In one implementation, such as Figure 13 As shown, the bottom of the water purification storage chamber 131 is connected to the top of the container 1512, so that the water in the water purification storage chamber 131 can be drained.

[0324] In one implementation, such as Figure 13 As shown, the low water level detection box 151 is slender, and its length extends along the height direction of the host 1, reducing the occupancy of the horizontal space in the host 1.

[0325] Furthermore, such as Figure 9 and Figure 13As shown, the cross-sectional area of ​​the cavity 1512 is smaller than that of the water storage cavity 252. The water storage cavity 252 makes full use of the lateral space in the kettle seat 22 to maximize its volume, so that the water above the low water level in the water storage cavity 252 can provide sufficient buoyancy for the first float 2511, preventing the suction force of the first pump body 161 from directly sucking the first float 2511 to the bottom of the water storage box 25. Preferably, the cross-sectional area of ​​the cavity 1512 is one-third to one-half of the cross-sectional area of ​​the water storage cavity 252.

[0326] In one implementation, such as Figure 13 As shown, the second low water level detection mechanism includes a matching second float 1511 and a second liquid level sensor (not shown in the figure); the second float 1511 is located in the cavity 1512, and the second liquid level sensor is connected to the outside of the low water level detection box 151.

[0327] Furthermore, such as Figures 13 to 14 As shown, the main unit 1 also includes a first pump body 161. Under the hydrodynamic force provided by the first pump body 161, the purified water tank 13 and the kettle body 21 supply water to the main unit's water supply port 14 simultaneously. The second float 1511 can move between a first position and a second position, with the second position located below the first position. The height of the second position in the cavity 1512 is h1. Since the first pump body 161 has a certain suction force, to prevent the first pump body 161 from directly sucking the second float 1511 to the bottom of the low water level detection box 151, the height h1 is configured such that the buoyancy force on the second float 1511 is greater than the suction force on the second float 1511 from the first pump body 161, thus preventing the second float 1511 from falling past the second position. Preferably, the height h1 is one-third to one-half of the height of the cavity 1512.

[0328] Furthermore, such as Figure 13 As shown, the low water level detection box 151 is provided with a float limiting post 1515, and the float limiting post 1515 is provided with a first limiting piece 1516 and a second limiting piece 1517. The second float 1511 is movably installed on the float limiting post 1515 and is located between the first limiting piece 1516 and the second limiting piece 1517. The first limiting piece 1516 is located above the second limiting piece 1517. The position of the first limiting piece 1516 is the first position mentioned above, and the position of the second limiting piece 1517 is the second position mentioned above.

[0329] In one implementation, such as Figure 13 and Figure 15As shown, the purified water tank 13 is provided with a tank connection port 132 and an interception structure 133. The tank connection port 132 is used to communicate with the cavity 1512, and the interception structure 133 is used to prevent foreign objects in the purified water storage cavity 131 from entering the cavity 1512 through the tank connection port 132. Specifically, since the space of the cavity 1512 is limited, if foreign objects enter the cavity 1512 through the tank connection port 132, it is inconvenient to clean them, and may even lead to the need to replace the low water level detection box, increasing the burden of use.

[0330] Furthermore, such as Figure 15 As shown, the interception structure 133 includes an annular portion 1331 and multiple interception ribs 1332. The number of interception ribs 1332 can be two, three, four, or even more, and all the interception ribs 1332 are spaced apart circumferentially along the annular portion 1331. The annular portion 1331 is positioned opposite the tank body connection port 132 in its own axial direction. One end of the interception rib 1332 is connected to the annular portion 1331, and the other end of the interception rib 1332 is connected to the tank body of the water purification tank 13. The interception effect can be adjusted by adjusting the spacing between two adjacent interception ribs 1332. Preferably, the tank body connection port 132 is a circular through hole with a diameter ≥ 5 mm to ensure smooth water inlet and outlet of the water purification tank 13.

[0331] In one embodiment, the main unit 1 further includes a high water level detection mechanism. When the kettle 2 is not connected to the main unit 1, the high water level detection mechanism is used to obtain high water level information in the purified water storage chamber 131. When the kettle 2 is connected to the main unit 1, the high water level detection mechanism determines that the kettle body 21 and the purified water tank 13 have reached their respective preset high water levels by obtaining the high water level information in the purified water storage chamber 131. Specifically, when the water in both the kettle body 21 and the purified water tank 13 is in a static state and has not reached the corresponding low water level, the water levels in both the kettle body 21 and the purified water tank 13 are equal. By using the high water level detection mechanism as the high water level detection mechanism for the entire machine, there is no need to additionally configure a corresponding high water level detection mechanism on the kettle 2, which simplifies the structure of the kettle 2 and reduces processing costs.

[0332] Furthermore, such as Figure 13 As shown, the main unit 1 also includes a high water level detection box 152, which is located in the purified water storage chamber 131. The high water level detection box 152 includes a cavity 1522, and a fifth through hole 1523 is provided on the side wall of the high water level detection box 152. The cavity 1522 is connected to the purified water storage chamber 131 through the fifth through hole 1523. The high water level detection mechanism includes a cooperating third float 1521 and a third liquid level sensor, with the third float 1521 located in the cavity 1522.

[0333] In one embodiment, when the kettle 2 is connected to the main unit 1 and the water purification device 100 is in the first working mode, when the water purification device 100 starts producing water, the purified water tank 13 and the kettle 2 are replenished with water separately and simultaneously. Some existing water purification devices, when starting water production, first replenish the purified water tank, and then the purified water tank replenishes the kettle. This replenishment process is time-consuming and the water level detection is inaccurate, or it requires separate water level detectors for the kettle and the purified water tank. In this solution, the purified water tank 13 and the kettle 2 are replenished separately and simultaneously, resulting in a shorter replenishment time.

[0334] Furthermore, such as Figure 9 As shown, when the kettle 2 is connected to the main unit 1 and the water purifier 100 is turned on to produce water, the purified water provided by the main unit 1 flows into the kettle cavity 215 through the water storage cavity 252. In this way, by setting the kettle body connection port 216 on the kettle body 21, the water inlet and outlet of the kettle body 21 can be realized without the need to open an additional water inlet on the kettle body 21, which can simplify the structure of the kettle body 21 and also simplify the pipeline connection relationship between the detachable kettle 2 and the main unit 1.

[0335] Furthermore, such as Figure 13 As shown, when the kettle 2 is connected to the main unit 1 and the water purifier 100 is turned on to produce water, the purified water provided by the main unit 1 enters the purified water storage chamber 131 through the container 1512. In this way, by setting the tank connection port 132 on the purified water tank 13, the water inlet and outlet of the purified water tank 13 can be realized without the need to open an additional water inlet on the purified water tank 13, which can simplify the structure of the purified water tank 13 and also simplify the pipeline layout in the main unit 1.

[0336] It should be understood that during the process of replenishing water to the water tank 13 and the kettle 2, one stream of water flows upward from the low water level detection box 151 into the water tank 13, and another stream of water flows upward from the water storage box 25 into the kettle body 21. The gas in the pipes, water tank 13 and water storage box 25 will be squeezed and discharged upward, which helps the water levels in the water tank and the kettle body to reach equilibrium as soon as possible, thereby increasing the accuracy of water level detection.

[0337] In one implementation, such as Figure 13 and Figure 18 As shown, when the kettle 2 is connected to the main unit 1, the kettle 2 is connected to the water collection component 18. When the water purification device 100 starts producing water, purified water enters the purified water tank 13 and the kettle 2 respectively through the water collection component 18. When the water purification device 100 starts supplying water, the purified water tank 13 and the kettle 2 supply water to the outside through the water collection component 18 respectively. In this solution, by configuring the water collection component 18, the inlet and outlet water paths of the purified water tank 13 and the kettle 2 are connected, which can reduce the number of pipes and pipe joints, simplify the pipe design, and thus reduce the risk of pipe blockage and the probability of pipe joint leakage to a certain extent.

[0338] Furthermore, such as Figure 3 , Figure 10 and Figure 13 As shown in Figure 13 , the clean water tank 13 is provided with a box body communication port 132, and the water kettle 2 is provided with a kettle body communication port 216. The water collection member 18 is respectively connected to the box body communication port 132 and the kettle body communication port 216; the clean water flows into or out of the clean water tank 13 through the box body communication port 132, and the clean water flows into or out of the water kettle 2 through the kettle body communication port 216. Specifically, the clean water tank 13 cooperates with the water collection member 18 through the box body communication port 132 to realize the water inlet and outlet of the clean water tank 13, and the water kettle 2 cooperates with the water collection member 18 through the kettle body communication port 216 to realize the water inlet and outlet of the water kettle 2. There are fewer openings on the clean water tank 13 and the water kettle 2, and there are fewer pipelines supporting the clean water tank 13 and the water kettle 2, which is beneficial to simplify the pipeline design of the water purification device 100.

[0339] Further, as Figure 13 、 Figure 10 and Figure 18 shown, the water collection member 18 is further provided with a first connection port 181 and a second connection port 182. The first connection port 181 is connected to the box body communication port 132 through a first pipeline 191, and the second connection port 182 is connected to the functional water tank 41 through a second pipeline 192. Of course, if the distance between the water collection member 18 and the box body communication port 132 or the functional water tank 41 is relatively close, the first pipeline 191 or the second pipeline 192 may not be provided, or both pipelines may not be provided. The first connection port 181 is directly connected to the box body communication port 132, or the first connection port 181 is directly connected to the low water level detection box 151 supporting the clean water tank 13; the second connection port 182 is directly connected to the first attachment docking module 43 of the functional water tank 41.

[0340] In an embodiment, as Figure 10 and Figure 18 shown, the water collection member 18 is further provided with a third connection port 183 and a fourth connection port 184. The third connection port 183 is connected to the clean water outlet of the filter element assembly 171, and the fourth connection port 184 is used to supply water to the main machine water supply port 14 of the water purification device 100. In this way, through the four connection ports opened on the water collection member 18, the water connection with the clean water tank 13, the functional water machine 4, the filter element assembly 171, and the main machine water supply port 14 can be realized. The structure of the water collection member 18 is simple, and only four-way water connection relationships are required, thereby reducing the number of pipelines and pipeline joints.

[0341] Further, as Figure 17 shown, a second pump body 162 is provided in the main machine 1. Under the power provided by the second pump body 162, the raw water enters the filter element assembly 171 and is discharged after being purified by the filter element assembly 171. In order to ensure that the water has sufficient power to flow through the filter element assembly 171, the second pump body 162 is selected as a booster pump.

[0342] In an embodiment, as Figure 10 and Figure 18 As shown, the water collection assembly 18 also has a fifth connection port 189. When the kettle 2 is connected to the main unit 1, the fifth connection port 189 is connected to the kettle 2 through the fourth pipe 195, and purified water flows into or out of the kettle 2 through the water collection assembly 18. In this way, the water collection assembly 18 can achieve water circuit connection with the water purification tank 13, the functional water machine 4, the kettle 2, the filter element assembly 171, and the main unit's water supply port 14 through the five connection ports. Only five water circuit connections are needed, thereby reducing the number of pipes and pipe joints.

[0343] Specifically, in one embodiment, the kettle base 22 is detachably connected to the main unit 1, and the fourth pipe 195 is connected to the second attached water channel connection element 2222 on the kettle base 22. The second attached water channel connection element 2222 communicates with the water storage cavity 252 in the kettle base 22, and the water storage cavity 252 communicates with the kettle cavity 215 of the kettle body 21, thereby realizing fluid flow between the kettle 2 and the main unit 1. In another embodiment, the kettle base 22 is fixedly connected to the main unit 1, and one end of the fourth pipe 195 communicates with the water storage box 25 in the kettle base 22. The water storage cavity 252 of the water storage box 25 communicates with the kettle cavity 215 of the kettle body 21, thereby realizing fluid flow between the kettle 2 and the main unit 1.

[0344] In one embodiment, the filter assembly 171 has a purified water outlet (not shown), such as Figure 10 As shown, the water collection component 18 is located below the purified water outlet. On the one hand, it utilizes the empty space below the filter element assembly 171 to accommodate the water collection component 18, minimizing changes to the placement of other components in the main unit 1. On the other hand, it can shorten the distance between the water collection component 18 and the filter element assembly 171, which helps to reduce the number of pipes, thereby reducing the risk of pipe blockage and the probability of pipe joint leakage. Alternatively, it can help to shorten the length of the pipes, thereby reducing the difficulty of pipe layout and reducing the space occupied by the pipes. In addition, the water flowing out of the purified water outlet has a certain pressure because it has been pressurized by the booster pump or tap water. When the purified water tank and the kettle are bottom-inlet, it can help the water level in the purified water tank and the kettle reach equilibrium as soon as possible, thereby increasing the accuracy of water level detection.

[0345] Furthermore, such as Figure 17 and Figure 18 As shown, the top wall of the water collection component 18 is provided with a third connection port 183, which is directly connected to the purified water outlet of the filter element assembly 171. Preferably, the water collection component 18 is located directly below the purified water outlet to shorten the distance between the two and facilitate direct communication.

[0346] In one implementation, such as Figure 3 , Figure 10 and Figure 13As shown, the tank body connection port 132 of the water purifier 13, the kettle body connection port 216 of the kettle 2, and the water collection component 18 are distributed from top to bottom. Specifically, the kettle body connection port 216 is lower than the tank body connection port 132 so that when the water purifier 100 is in the first working mode, the water storage box 25 of the kettle 2 can be used to detect the low water level of the whole machine; the water collection component 18 is lower than the kettle body connection port 216 and the tank body connection port 132. In this way, when the water purifier 13 and the kettle 2 supply water to the outside through the main unit water supply port 14, if the water level in the water purifier 13 and the kettle 2 drops to the low water level, the water collection component 18 is lower than the low water level position, so backflow will not occur. Moreover, when the user takes hot water, it can avoid steam spraying at the main unit water supply port 14 caused by the pump running dry. Of course, the water manifold 18 can also be positioned higher than the kettle body connection port 216 and the box body connection port 132, and a control valve can be configured to prevent backflow, which will also lead to a corresponding increase in the number of joints in the pipeline.

[0347] In one implementation, such as Figure 10 and Figure 13 As shown, the water purification tank 13 is located above the water collection component 18. The kettle body connection port 216 of the kettle 2, the water collection component 18, the tank body connection port 132 of the water purification tank 13 and the functional water machine 4 are distributed in sequence in the left and right directions of the water purification equipment 100, which facilitates the arrangement of pipes.

[0348] Furthermore, such as Figure 13 As shown, the water purification device 100 includes a main housing 12, a main water supply port 14 is installed on the front side of the main housing 12, and a water collection component 18 is located in the front part of the main housing 12, which helps to shorten the distance between the water collection component 18 and the main water supply port 14 in the front-back direction, thereby shortening the length of the third pipe 193 used to discharge water from the water collection component 18.

[0349] Furthermore, such as Figure 10 and Figure 18 As shown, the water collection component 18 is provided with a fourth connection port 184 facing the first side wall 1851 of the functional water machine 4. The fourth connection port 184 supplies water to the outside through the third pipe 193. The fourth connection port 184 is located at the front of the first side wall 1851 to shorten the distance between the fourth connection port 184 and the main unit water supply port 14 in the front-back direction, thereby shortening the length of the third pipe 193.

[0350] Furthermore, such as Figure 10 , Figure 13 and Figure 18As shown, the first sidewall 1851 is provided with a first connection port 181, which is connected to the housing connection port 132 through a first pipe 191. The first connection port 181 is located at the rear of the first sidewall 1851. Specifically, the water purification tank 13 is located behind the main unit's water supply port 14. By placing the first connection port 181 behind the fourth connection port 184, the limited space on the first sidewall 1851 is utilized effectively, which helps to shorten the distance between the first pipe 191 and the water purification tank 13 in the front-to-back direction, thereby shortening the length of the first pipe 191.

[0351] Furthermore, such as Figure 10 , Figure 13 and Figure 17 As shown, a low water level detection box 151 is connected to the bottom of the water purification tank 13. The first pipe 191 extends upward to connect with the low water level detection box 151. Purified water flows into or out of the water purification tank 13 through the low water level detection box 151. Specifically, in the vertical direction of the water purification device 100, the low water level detection box 151 is located between the water purification tank 13 and the water collection component 18. The distance between the first connection port 181 of the low water level detection box 151 and the water collection component 18 is short. Connecting the first pipe 191 to the low water level detection box 151 and the water collection component 18 respectively, so that the water purification tank 13 is connected to the water collection component 18, can help shorten the length of the first pipe 191.

[0352] Furthermore, such as Figure 13 and Figure 17 As shown, both the housing connection port 132 and the low water level detection box 151 are located behind the water collection component 18. The low water level detection box 151 includes a vertical box body 1513 and a horizontal box body 1514, with the horizontal box body 1514 extending along the front-rear direction of the water purification device 100. The vertical box body 1513 is connected to the bottom of the water purification tank 13, and a second float 1511 is provided in the vertical box body 1513. The second float 1511 moves within the vertical box body 1513 to detect water level information. The rear end of the horizontal box body 1514 is connected to the vertical box body 1513, and the front part of the horizontal box body 1514 is connected to the first pipe 191. In this solution, by configuring the horizontal box body 1514 on the low water level detection box 151, the distance between the low water level detection box 151 and the first connection port 181 in the front-rear direction can be shortened, thereby further shortening the length of the first pipe 191.

[0353] Furthermore, such as Figure 13 As shown, a connecting pipe 15141 is provided on the bottom wall of the front part of the horizontal box 1514. The connecting pipe 15141 extends downward and communicates with the first pipe 191. The setting of the connecting pipe 15141 can shorten the vertical distance between the low water level detection box 151 and the first connection port 181, thereby further shortening the length of the first pipe 191.

[0354] In one implementation, such as Figure 10 and Figure 17 As shown, the first pump body 161 in the main unit 1 is vertically positioned below the water purification tank 13. The third pipe 193 is connected to the inlet end of the first pump body 161. Optimizing the position of the first pump body 161 shortens the distance between the fourth connection port 184 of the water collection component 18 and the inlet end of the first pump body 161 in the vertical direction of the water purification device 100, which helps to shorten the length of the third pipe 193. Under the water power provided by the first pump body 161, the water purification tank 13 and the kettle 2 respectively supply water to the main unit's water supply port 14.

[0355] Furthermore, such as Figure 17 As shown, the outlet end of the third pipe 193 extends upward to connect with the bottom of the first pump body 161, which further facilitates shortening the length of the third pipe 193.

[0356] Furthermore, such as Figure 10 and Figure 17 As shown, the first pump body 161 is located in front of the vertical box 1513, and the projection of the first pump body 161 in the downward direction falls at least partially on the horizontal box 1514. The low water level detection box 151 and the first pump body 161 are arranged compactly, with high space utilization.

[0357] Furthermore, such as Figure 10 and Figure 17 As shown, the outlet end of the third pipe 193 is located on the side of the horizontal box 1514 facing the functional water machine 4, and the outlet end of the third pipe 193 is set close to the horizontal box 1514, which is reasonable and compact.

[0358] Furthermore, the lateral distance between the outlet end of the third pipe 193 and the transverse box 1514 is less than or equal to 1 cm, and the third pipe 193 and the transverse box 1514 are arranged compactly, with high space utilization.

[0359] In one implementation, such as Figure 10 and Figure 17 As shown, the water purification device 100 also includes a heating element 172. The purified water pumped out by the first pump body 161 is supplied to the main unit's water supply port 14 via the heating element 172. Specifically, when the user takes room temperature water, the heating element 172 does not work, and the purified water flows to the main unit's water supply port 14 via the heating element 172; when the user takes hot water, the heating element 172 works, the purified water flows into the heating element 172, is heated by the heating element 172 to form hot water, and then flows to the main unit's water supply port 14.

[0360] Furthermore, such as Figure 10 and Figure 17As shown, the heating element 172 is located between the transverse box 1514 and the filter assembly 171. The bottom of the first pump body 161 is connected to the water outlet pipe 194, which bypasses the transverse box 1514 to connect to the bottom of the heating element 172. By optimizing the arrangement of the heating element 172 and the layout of the water outlet pipe 194, it is beneficial to shorten the length of the water outlet pipe 194.

[0361] Furthermore, such as Figure 10 As shown, a drain component 173 is provided on the water outlet pipe 194. The drain component 173 is used for manual drainage. The drain component 173 can be manually opened to drain water. When the water purification equipment 100 malfunctions and needs to be repaired, the water in the pipeline of the water purification equipment 100 needs to be drained first. If the water supply port 14 of the main unit has a water outflow failure, it can be manually drained through the drain component 173 to ensure that the maintenance work can be carried out smoothly.

[0362] In one implementation, such as Figure 10 and Figure 18 As shown, the water manifold 18 has a second connection port 182 on its second side wall 1852 away from the main unit's water supply port 14. The second connection port 182 is connected to the functional water tank 41 through the second pipe 192. By optimizing the positional relationship of each interface of the water manifold 18, the water manifold 18 can be miniaturized as much as possible while integrating multiple pipes, thus reducing the space occupied by the water manifold 18.

[0363] Furthermore, such as Figure 10 As shown, the second pipe 192 extends in the horizontal plane. Specifically, the main unit 1 connects to the first attachment docking module 43 of the functional water machine 4 through the first expansion function module 11, and sets the input end of the first main unit water circuit docking element 111 of the first expansion function module 11, the outlet end of the second pipe 192 and the second connection port 182 at the same horizontal height. In this way, the second pipe 192 can be arranged to extend along the horizontal plane, reducing the vertical space occupied by the second pipe 192.

[0364] Furthermore, such as Figure 10 and Figure 18 As shown, the fifth connection port 189 is located on the second side wall 1852, and the second connection port 182 and the fifth connection port 189 are distributed sequentially in the direction toward the kettle 2. The five connection ports on the water collection component 18 are arranged compactly, maximizing the use of the limited space on the outer peripheral side wall of the water collection component 18, and also facilitating the orderly arrangement of the first pipe 191, the second pipe 192, the third pipe 193 and the fourth pipe 195.

[0365] In one implementation, such as Figure 18 and Figure 19As shown, the water collection component 18 is provided with a water storage cavity 186, which is used to communicate with the purified water tank 13, the kettle 2, and the functional water tank 41. By providing a water storage cavity 186 on the water collection component 18 to buffer the fluid, when the water purification device 100 is turned on to produce water, the water collection component 18 is in a one-in-two-out state, that is, the third connection port 183 is used to supply purified water provided by the filter element assembly 171, the first connection port 181 supplies water to the purified water tank 13, and the fifth connection port 189 supplies water to the kettle 2. In this state, the fluid buffered in the water storage cavity 186 can help improve the stability of the water output from the first connection port 181 and the fifth connection port 189.

[0366] Furthermore, such as Figure 18 and Figure 19 As shown, the water collection component 18 is equipped with a temperature detection element 187 to obtain water temperature information in the water storage cavity 186. Specifically, since the water purification device 100 is equipped with a purified water tank 13 and a water jug ​​2, with the purified water tank 13 located inside the main housing 12 and the water jug ​​2 exposed, the ambient temperatures of the purified water tank 13 and the water jug ​​2 may differ, resulting in a difference in water temperature between the two. When the water purification device 100 is in the first working mode, water is supplied simultaneously by the purified water tank 13 and the water jug ​​2 when the user takes water. Therefore, it is necessary to detect the temperature of the water after mixing in the purified water tank 13 and the water jug ​​2. If only an NTC element is installed in the purified water tank 13, inaccurate water temperature detection will occur. This can lead to either excessively high water temperature causing excessive steam spraying or excessively low water temperature, failing to meet user needs. In this method, a water storage cavity 186 is set on the water collection component 18 and a temperature detection element 187 is configured. The purified water tank 13 and the kettle 2 are first mixed in the water storage cavity 186. Then, the temperature of the mixed water in the water storage cavity 186 is initially detected by the temperature detection element 187 before the water is supplied to the heating element 172. This can improve the accuracy of temperature detection and avoid problems such as excessive steam spraying or excessively low water temperature in the heating element 172.

[0367] In one implementation, such as Figure 18 and Figure 19As shown, the bottom wall of the water storage cavity 186 is provided with a flow guiding groove 1861, and the first connection port 181, the second connection port 182 and the fourth connection port 184 are respectively connected to the flow guiding groove 1861. Specifically, when the water purifier 100 in the first working mode starts producing water, because the guide groove 1861 is low, the water entering from the third connection port 183 can quickly enter the guide groove 1861, and then be quickly supplied to the water tank 13 through the first connection port 181. The remaining water is supplied to the kettle 2 through the fifth connection port 189. When the water purifier 100 in the first working mode starts supplying water, the water in the water tank 13 enters the guide groove 1861 through the first connection port 181, and the water in the kettle 2 enters the water storage cavity 186 through the fifth connection port 189 and then enters the guide groove 1861. The water in the guide groove 1861 can quickly enter the fourth connection port 184 connected to it, and supply water to the first pump body 161 through the fourth connection port 184.

[0368] Furthermore, such as Figure 18 and Figure 19 As shown, the flow guide groove 1861 includes a first groove 18611 and a second groove 18612 that are interconnected. The first groove 18611 is located on the side of the water storage cavity 186 near the functional water machine 4. The first connection port 181, the second connection port 182, and the fourth connection port 184 are respectively connected to the first groove 18611. The outlet end of the third connection port 183 of the water collection component 18 is located above the second groove 18612. The third connection port 183 is used to allow purified water supplied by the filter element assembly 171 to flow in. Specifically, when the water purification device 100 in the first working mode starts producing water, the water flowing into the third connection port 183 first enters the second groove 18612 and then flows into the first groove 18611, which can reduce the degree of water flow turbulence and reduce noise to a certain extent.

[0369] Furthermore, such as Figure 18 As shown, the first tank 18611 includes a first tank wall 186111, which is connected to the second tank 18612. The first tank wall 186111 extends inclined in a downward direction away from the second tank 18612. The inclined arrangement of the first tank wall 186111 can guide the flow of water in the second tank 18612 to the first tank 18611.

[0370] In one implementation, such as Figure 18 and Figure 19 As shown, the water collection component 18 includes a detachably connected water collection box 1881 and a water collection cover 1882, which are sealed together to form a water storage cavity 186. The water collection component 18 is configured as a split structure to facilitate the cleaning of the inner wall of the water collection component 18.

[0371] In one embodiment, the volume of the water-storing cavity 186 is greater than or equal to 18 cm³. 3 To maximize the use of the empty internal space at the bottom of the purified water outlet of the filter element assembly 171, and to maximize the volume of the water storage cavity 186, so as to avoid the first pump body 161 from being pumped dry.

[0372] In one implementation, such as Figure 3 and Figure 10 As shown, when the kettle 2 is connected to the main unit 1, the water collection component 18 is located below the low limit position of the first float 2511. Specifically, when the water purifier 100 in the first working mode starts supplying water, the water in the kettle 2 first enters the water collection component 18 and then flows to the first pump body 161. If the position of the water collection component 18 is higher than the low limit position of the first float 2511, when the water in the water collection component 18 is emptied, the first float 2511 in the water storage box 25 has not yet reached its low limit position, which causes the first pump body 161 to still pump water. If hot water is being drawn at this time, the empty pump will also cause steam to spray, which poses a potential safety hazard. Therefore, this solution sets the position of the water collection component 18 below the low limit position of the first float 2511 to avoid the occurrence of empty pump.

[0373] In one implementation, such as Figure 16 As shown, the kettle body 21 is also provided with a spout 218 and a handle 219. The spout 218 is used to pour water, and the handle 219 is used for the user to hold.

[0374] It should be understood that "water production" in this article refers to the process by which the water purification equipment 100 purifies the raw water.

[0375] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims.

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