Description

Technical Field

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

[0002] Water purification equipment provides users with purified water that is safe to drink directly and is widely used in homes, offices, and other places. As users' functional needs for water purification equipment become increasingly diverse, single-configuration systems are no longer sufficient to meet the needs of more diverse user groups.

[0003] Some existing water purification devices enrich their functionality by adding a detachable kettle. Specifically, the main unit of the water purification device has an integrally formed mounting base, and the detachable kettle is detachably installed on the mounting base. The main unit has a connecting device, and the detachable kettle is connected to the water passage of the connecting device. The main unit determines the water level information in the detachable kettle by obtaining the water level in the connecting device. When the water purification device is also equipped with a purified water tank, and the purified water tank is connected to the connecting device, if, for some reason (e.g., the cross-sectional area of ​​the detachable kettle's cavity is larger than the cross-sectional area of ​​the purified water tank's chamber on the same horizontal plane, or the bottom wall of the detachable kettle's cavity is located below the purified water tank's chamber), the water level in the detachable kettle drops more slowly than in the purified water tank, the main unit will determine that the water level in the purified water tank has reached the low water level and stop supplying water. At this time, the water level in the detachable kettle has not yet reached the corresponding low water level, causing stagnant water to accumulate in the connecting device, which is not conducive to healthy drinking.

[0179] Preferably, the volume of the water-storing cavity is greater than or equal to 18 cubic centimeters.

[0180] Preferably, the water purification device includes a main unit and a detachable kettle, wherein the detachable kettle is at least partially detachably connected to the main unit;

[0181] When the detachable kettle is connected to the main unit, the detachable kettle is in communication with the water collection component.

[0182] Preferably, the detachable kettle includes a first low water level detection mechanism and a kettle body and a water storage cavity that are interconnected, wherein the lowest point of the water storage cavity is located below the lowest point of the kettle body's cavity;

[0183] The first low water level detection mechanism determines that the water level in the kettle has reached a preset low water level by acquiring the low water level information in the water storage chamber.

[0184] Preferably, the first low water level detection mechanism includes a first float and a first liquid level sensor that cooperate with each other, and the first float is located in the water storage cavity;

[0185] When the detachable kettle is connected to the main unit, the water collection component is located below the low limit position of the first float.

[0186] This utility model has the following technical effects:

[0187] This utility model provides a water purification device, including a water tank, a kettle base, a kettle body, and a first low water level detection mechanism. The kettle body increases the water storage capacity of the device, and users can remove the kettle body to directly draw water, allowing for quick and easy access to the required amount of water, thus enhancing its functionality. When the water purification device is turned on, water in the kettle body flows through the water storage chamber to the main unit's water inlet. Furthermore, the lowest point of the water storage chamber is located below the lowest point of the kettle body's cavity, facilitating the efficient drainage of water from the kettle cavity.

[0188] Furthermore, when the kettle is installed on the kettle base and the water purification equipment is in the first working mode, the kettle and the purified water tank are connected. When the water in both the kettle and the purified water tank is in a static state and has not reached the corresponding low water level, the water levels in the kettle and the purified water tank are equal. In this way, the water level detection mechanism configured in the water purification equipment can detect the water levels in both the kettle and the purified water tank simultaneously. However, during the process of water supply to the kettle and the purified water tank separately and simultaneously, if, for some reason (for example, the cross-sectional area of ​​the kettle is larger than the cross-sectional area of ​​the purified water tank on the same horizontal plane), the water level in the kettle drops more slowly than that in the purified water tank, the water purification equipment in this solution is equipped with a first low water level detection mechanism to detect the low water level information in the water storage chamber, so as to ensure that the water in the kettle can be used up to the preset low water level of the kettle, reduce stagnant water, and ensure healthy drinking water.

[0232] In this utility model, "front," "rear," "left," "right," "up," and "down" all refer to... Figure 1 and Figure 10 The markings in the text shall prevail.

[0233] The following is based on Figures 1 to 19This utility model describes the water purification equipment in detail.

[0234] 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 detachable kettle 2. 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 also 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. Figure 1 As shown, the detachable kettle 2 includes a detachably connected kettle body 21 and a kettle base 22, with the kettle base 22 detachably connected to the main unit 1. Figure 10 and Figure 16 As shown, when the kettle base 22 is connected to the main unit 1, the kettle base 22 and the main unit 1 are connected by water channels, so that the main unit 1 supplies water to the kettle body 21 through the kettle base 22.

[0235] In the above technical solution, by configuring a detachable kettle 2, the water storage capacity of the water purifier 100 is increased. Furthermore, the kettle body 21 of the detachable kettle 2 is detachably connected to the kettle base 22. When the kettle base 22 is connected to the main unit 1, the main unit 1 supplies water to the kettle body 21 through the kettle base 22. The kettle body 21 is not directly connected to the main unit 1, which facilitates quick removal or installation of the kettle body 21. This makes it easy to handle and operate with ease and effort. Users can remove the kettle body 21 to directly take water. In this way, users can quickly obtain the required amount of water according to their water needs, thus enriching the functionality. Furthermore, the kettle base 22 is detachably connected to the main unit 1. If any pipes or components in the kettle base 22 malfunction, the kettle base 22 can be removed for timely repair or replacement. This detachable connection also caters to various user needs. For example, if the user does not wish to use the detachable kettle body 21 or if space is limited, the kettle base 22 and kettle body 21 can be removed together for storage. This avoids the accumulation of dust and dirt on the kettle base 22 due to only removing the kettle body 21, which could contaminate the water purification system. Additionally, the detachable kettle base 22 avoids taking up too much space. It should be understood that during normal use of the detachable kettle 2, the kettle base 22 remains connected to the main unit 1; only the kettle body 21 needs to be removed, reducing the user's burden.

[0236] In one implementation, such as Figure 10 As shown, when the kettle base 22 and the main unit 1 are connected, the kettle base 22 and the main unit 1 are electrically connected. The electrical connection between the kettle base 22 and the main unit 1 can be used to transmit signals, or the main unit 1 can supply power to the kettle base 22. Of course, it can also be used for both signal transmission and power supply.

[0237] 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.

[0238] Furthermore, such as Figure 1 and Figure 12 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.

[0239] Furthermore, such as Figure 2 As 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 1 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.

[0240] Furthermore, such as Figure 1 , Figure 3 and Figure 12 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.

[0241] In one implementation, such as Figures 1 to 3As shown, the detachable kettle 2 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 between the kettle body 21 and the kettle base 22.

[0242] 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.

[0243] In one implementation, such as Figure 1 and Figure 8 As shown, the main unit 1 also includes an expansion function module 11, and the kettle base 22 is provided with an attachment docking module 222. The expansion function module 11 and the attachment docking module 222 cooperate to allow the kettle base 22 to be detachably connected to the main unit 1.

[0244] Furthermore, such as Figure 1 and Figure 8As shown, the extended function module 11 includes a main unit water circuit connection element 111, and the attached connection module 222 includes an attached 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 the multi-functional operating mode, a detachable kettle 2 is installed on the extended function module 11, and the main unit water circuit connection element 111 connects with the attached water circuit connection element 2221 so that the main unit 1 supplies water to the detachable kettle 2. The main unit 1 and the detachable kettle 2 work together, and the detachable kettle 2 can use the purified water provided by the main unit 1. When the water purification device 100 is in the standalone operating mode, the detachable kettle 2 is not installed on the extended function module 11, the main unit 1 operates independently, and the purified water is provided for drinking through the filter element assembly 171 of the main unit 1.

[0245] With the above setup, users can first meet their need for direct drinking purified water through the main unit 1; secondly, by connecting the detachable kettle 2 through the expansion function module 11, water can be supplied to the detachable kettle 2 based on the main unit 1, saving some of the structure of the detachable kettle 2, resulting in good integration and low cost.

[0246] Furthermore, such as Figure 1 and Figure 8 As shown, the extended function module 11 also includes a main electrical connection element 112, and the attachment connection module 222 also includes an attachment electrical connection element 2222. When the water purifier 100 is in multi-functional mode, the main electrical connection element 112 connects with the attachment electrical connection element 2222, and the main unit 1 supplies power to the detachable kettle 2 and / or the main unit 1 and the detachable kettle 2 exchange signals.

[0247] In one implementation, such as Figure 1 and Figure 8 As shown, the main water circuit connection element 111 and the auxiliary water circuit connection element 2221 constitute a water valve assembly. When the main water circuit connection element 111 and the auxiliary water circuit connection element 2221 are in the connected state, the main water circuit connection element 111 and the auxiliary water circuit connection element 2221 are in the open state respectively. The main unit 1 and the detachable water bottle 2 can achieve fluid flow through the main water circuit connection element 111 and the auxiliary water circuit connection element 2221. When the auxiliary water circuit connection element 2221 is disconnected from the main water circuit connection element 111, the main water circuit connection element 111 is in the closed state to prevent water in the main unit 1 from flowing out from the main water circuit connection element 111, and the auxiliary water circuit connection element 2221 is in the closed state to prevent water in the detachable water bottle 2 from flowing out from the auxiliary water circuit connection element 2221.

[0248] Furthermore, one of the main electrical connection element 112 and the attached electrical connection element 2222 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 1 and Figure 8 As shown, the main electrical connector 112 is the female end of the coupler, and the attached electrical connector 2222 is the male end of the coupler, facilitating connection and avoiding the need for a complex waterproof structure for the main electrical connector 112. Specifically, the 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 detachable kettle, the main detection terminal determines whether the detachable kettle is connected, and the main signal terminal sends and / or receives information from the detachable kettle. In actual product applications, different types and numbers of terminals are set according to product requirements. For example, to facilitate user installation, the main electrical connector 112 includes a main power supply terminal, thus eliminating the need for an additional socket for the detachable kettle in the installation scenario. For example, to save costs and facilitate user operation on a single interface, the main electrical connector 112 includes a main signal terminal.

[0249] In one embodiment, the expansion function module 11 is retractably installed on the main unit 1. In standalone operating mode, the expansion function module 11 is in a retracted state, with at least the main unit water connection element 111 and the main unit electrical connection element 112 located inside the main unit 1, improving the overall aesthetics. Preferably, in standalone operating mode, the 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 protection. Figure 1 and Figure 10 As shown, when in the multi-functional working mode, at least the main unit water circuit connection element 111 and the main unit electrical connection element 112 in the expansion function module 11 are located outside the main unit 1 so that the detachable kettle 2 of the functional water purifier can be smoothly connected to the expansion function module 11. Preferably, when the water purifier 100 is in the multi-functional working mode, at least the main unit electrical connection element 112 and the main unit water circuit connection element 111 in the expansion function module 11 are exposed and installed on the main unit 1 for the installation of the detachable kettle 2.

[0250] In one embodiment, the extended function module 11 is disposed on the lower side of the main unit 1. The bottom of the extended function module 11 can abut against the mounting platform. After docking with the detachable kettle 2, it can minimize or even avoid bearing the weight exerted on it by the detachable kettle 2, thereby ensuring that the extended function module 11 has the characteristics of small positional deformation and high docking accuracy during long-term use.

[0251] In yet another implementation, such as Figure 1 As shown, the expansion function module 11 is disposed on one side wall of the main unit 1, facing the detachable kettle 2. Specifically, the expansion function module 11 is disposed on the lower part of one side of the main unit 1, and the detachable kettle 2 is inserted into the main unit electrical connection element 112 and the main unit water connection element 111 in the expansion function module 11 along the left and right directions, respectively. In this embodiment, it is worth noting that the expansion function module 11 is fixedly disposed on the main unit 1. The protruding direction of the main unit electrical connection element 112 is parallel to the docking direction of the detachable kettle 2, and the protruding direction of the main unit electrical connection element 112 is parallel to the bottom surface of the main unit 1. The extending direction of the main unit water connection element 111 is parallel to the bottom surface, so as to allow the detachable kettle 2 to be inserted laterally. The detachable kettle 2 docks with the main unit 1 in the vertical direction. The protruding direction of the main unit electrical connection element 112 is perpendicular to the bottom surface of the main unit 1, and the extending direction of the main unit water connection element 111 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 removable kettle 2 being moved due to vibration of the second pump body 162 (typically a booster pump used to pump water out of the filter assembly 171).

[0252] In one implementation, such as Figure 1 As shown, for the storage of the expansion function module 11, the main unit 1 has a receiving cavity 122 on the main unit shell 12. The receiving 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 expansion function module 11 between the standalone working mode and the multi-functional working mode.

[0253] Furthermore, to facilitate easy switching of the relative position of the expansion function module 11, a slide rail (not shown in the figure) is provided in the accommodating cavity 122, and a slide groove (not shown in the figure) is provided on the expansion function module 11. The slide rail and the slide groove cooperate with each other to allow the 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.

[0254] In one implementation, such as Figure 11As shown, the 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 decorative cover 121. When the water purification device 100 is in standby mode, the decorative cover 121 covers the extended function module 11. When the extended function module 11 is stored in the receiving cavity 122, due to the design requirements of the assembly space, the functional part of the extended function module 11 is still exposed to the air. For users with high cleanliness requirements, by setting the decorative cover 121, the functional part of the 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.

[0255] In an embodiment where the extended function module 11 is installed on the host 1 and housed in the receiving cavity 122, the decorative cover 121 can be inserted into the receiving cavity 122 to achieve the closing action of the extended function module 11.

[0256] In one implementation, such as Figure 1 As shown, the extended functional module includes a housing 113, a main unit electrical connection element 112 (such as a coupler), and a main unit water circuit connection element 111 (such as a stop valve) disposed on the housing 113. Specifically, the functional parts of the main unit electrical connection element 112 and the main unit water circuit connection element 111 are both disposed on the upper surface of the housing 113. During the docking process between the detachable 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.

[0257] Furthermore, the host electrical connection element 112 includes at least one conductive element. Even further, as... Figure 1 As shown, at least one waterproof component 114 is provided on the housing 113. The waterproof component 114 is correspondingly arranged with an electrical conductive component, and at least one electrical conductive component is located below its corresponding waterproof component 114. Preferably, the 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 attached electrical docking element 2222 squeezes the opening of the waterproof silicone sheet, passes through it, and docks with the electrical conductive component.

[0258] In one implementation, such as Figure 12 As shown, the main unit 1 also includes a water purification tank 13, and the main unit water circuit connection element 111 is in fluid communication with the water purification tank 13 so that the kettle body 21 is connected to the water purification tank 13.

[0259] In one implementation, such as Figure 4As 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 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.

[0260] 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 bracket 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 of the attached electrical connector 2222 is located in the receiving space 2214 and is electrically connected to the input of the adapter 223, which is also electrically connected to the kettle control board 224. The adapter 223 converts AC power to DC power to supply power to the kettle control board 224. Furthermore, the main control board in the host 1 outputs a signal line to the host electrical connector 112, while the attached electrical connector 2222 outputs a signal line to the kettle control board 224, enabling signal interaction between the host 1 and the detachable kettle 2.

[0261] Furthermore, such as Figure 5 and Figure 6 As 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 detachable 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.

[0262] In one implementation, such as Figures 8 to 10As shown, the lower surface of the base 2212 is recessed towards the bracket 2213 to form a recess 22122. The input end of the attachment docking module 222 is located in the recess 22122. When the kettle base 22 is installed on the main unit 1, the expansion function module 11 is inserted into the recess 22122 so that the expansion function module 11 cooperates with the attachment docking module 222. In this design, the recess 22122 is provided to accommodate the input end of the attachment docking module 222, preventing the attachment docking module 222 from protruding from the outside of the base 2212. This avoids the inconvenience of placing the kettle base 22 after it is removed, and provides protection for the attachment docking module 222 during transportation or use, preventing the attachment docking module 222 from being damaged.

[0263] Furthermore, such as Figure 8 and Figure 10 As shown, the bottom of the recess 22122 and its side facing the main unit 1 are both open. The expansion function module 11 is inserted into the recess 22122 from bottom to top. In this way, under the weight of the detachable kettle 2 itself, it is beneficial for the attachment docking module 222 and the expansion function module 11 to be stably docked. When the kettle base 22 is removed, the kettle base 22 moves upward to detach from the main unit 1. Specifically, since the water purification device 100 has a certain height, the application scenario of the water purification device 100 has sufficient space in terms of height. In this solution, the kettle base 22 is installed and removed in the vertical direction, making full use of the original height space of 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 main unit 1 in the horizontal or front-back direction, which is suitable for application scenarios with sufficient horizontal space.

[0264] In one implementation, such as Figure 5 and Figure 6 As 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, and the arrangement is compact, which is conducive to the miniaturization design 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 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, which facilitates neat wiring. Preferably, at least one side of the first wire hole 22124 is open to facilitate wire passing.

[0265] Furthermore, such as Figure 5 and Figure 6As 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 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 attached electrical connection element 2222, which helps to shorten the length of the first power cord.

[0266] 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 and the output end of the adapter 223 are positioned opposite each other 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.

[0267] 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.

[0268] In one implementation, such as Figure 5 and 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 of the detachable kettle 2, 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.

[0269] Furthermore, such as Figure 5As 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.

[0270] 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.

[0271] Furthermore, such as Figure 9 and Figure 10 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.

[0272] Furthermore, such as Figure 9 and Figure 10 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 expansion function module 11 along the first direction. Specifically, the main unit 1 connects to the detachable kettle 2 through the exposed expansion function module 11. The locking element 31 can directly abut against the expansion function module 11 to achieve locking, eliminating the need for additional components on the main unit 1 to abut against the locking element 31, reducing modifications to the structure of the main unit 1 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 opened on the main unit 1, and the locking element 31 can be inserted into the locking groove to achieve locking.

[0273] Furthermore, such as Figure 9 and Figure 10As 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 expansion function module 11 in the first direction. In one specific embodiment, the detachable 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 attachment docking module 222 is aligned downwards with the expansion function module 11 and docked. The locking element 31 in the unlocked position will not interfere with the expansion function module 11 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 expansion function module 11 in 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.

[0274] 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 expansion function module 11 in 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.

[0275] 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 ramp 3111. When the kettle seat 22 is assembled with the expansion function module 11 of the main unit 1, the guide ramp 3111 contacts and cooperates with the outer wall of the main unit to drive the locking element 31 to move to the unlocked position. As the kettle seat 22 moves downward until the guide ramp 3111 of the locking part 311 contacts the expansion function module 11, the guide ramp 3111 is subjected to the reaction force of the expansion function module 11 during the continued downward movement of the kettle seat 22, causing the locking part 311 to move to the unlocked position. This eliminates the need for manual manipulation of the locking element 31, facilitating assembly. In addition, a groove (not shown) can be provided on the extended function module 11. When the kettle seat 22 continues to move downward until it is docked with the extended function module 11, the locking part 311 continues to move from the above-mentioned unlocking position to the locking position. The whole process does not require manual operation of the locking element 31, which is convenient for assembly.

[0276] 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.

[0277] 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.

[0278] 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.

[0279] 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.

[0280] 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 during normal use.

[0281] 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.

[0282] In one implementation, such as Figure 3 and Figure 4 As shown, the detachable kettle 2 also includes an in-situ detection component 24, which is used to detect whether the kettle body 21 is installed in place.

[0283] 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.

[0284] 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.

[0285] 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.

[0286] 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.

[0287] 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.

[0288] 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.

[0289] 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.

[0290] In one implementation, such as Figure 9 , Figure 12 , Figure 13 As shown, the main unit 1 also includes a clean water tank 13 and a water supply outlet 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.

[0291] like Figure 12 As shown, the lowest point of the water storage chamber 252 is located below the lowest point of the kettle body 21's chamber 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. In this mode, the kettle chamber 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 water inlet 14 simultaneously. The water in the kettle body 21 flows to the water inlet 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 chamber 215 and the purified water tank 13 are not in communication.

[0292] In the above technical solution, when the water purifier 100 starts supplying water, the water in the kettle body 21 flows to the water inlet 14 of the main unit 1 through the water storage chamber 252. 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.

[0293] In one implementation, such as Figure 12 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.

[0294] In one implementation, such as Figure 12 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.

[0295] Furthermore, such as Figure 12 As shown, the bottom of the kettle cavity 215 is connected to the top of the water storage cavity 252. Specifically, as... Figure 16 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 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.

[0296] In one implementation, such as Figure 12 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.

[0297] Furthermore, such as Figure 9 , Figure 10 and Figure 12 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.

[0298] Furthermore, such as Figure 9 and Figure 12 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.

[0299] Furthermore, such as Figure 12 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.

[0300] In one implementation, such as Figure 4 and Figure 9 As shown, the water storage box 25 is disposed in the receiving space 2214 formed between the bracket 2213 and the base 2212. The water storage box 25 is located above the adapter 223 and the attachment docking module 222. The components are arranged compactly, and the space utilization rate is high.

[0301] 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.

[0302] Furthermore, such as Figure 9As 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.

[0303] 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.

[0304] 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.

[0305] 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.

[0306] 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 attached water circuit docking element 2221.

[0307] Furthermore, such as Figure 3 and Figure 9As 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 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 attached water circuit docking element 2221.

[0308] In one implementation, such as Figure 12 As shown, the capacity of the kettle body 21 is greater than that of the water tank 13, providing users with a large water storage capacity. 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, and the height of the water tank 13 is limited. 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. Therefore, by extending the height of the kettle body 21 as much as possible, the capacity of the kettle body 21 is increased. In this way, 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 detachable 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.

[0309] Furthermore, such as Figure 12 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.

[0310] In one embodiment, the main unit 1 further includes a second low water level detection mechanism. When the detachable 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.

[0311] Furthermore, such as Figure 12 and Figure 13 As 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 to the water supply port 14 through the cavity 1512, which helps to drain the water in the purified water storage chamber 131 as much as possible. In one specific embodiment, when the detachable kettle 2 is connected to the main unit 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 the 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.

[0312] Furthermore, such as Figure 12 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.

[0313] Furthermore, such as Figure 12 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 detachable 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 determine that the kettle body 21 and the purified water tank 13 have reached the corresponding preset low water level by obtaining the low water level information in the water storage chamber 252.

[0314] In one implementation, such as Figure 12 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.

[0315] In one implementation, such as Figure 12 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.

[0316] Furthermore, such as Figure 12As 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.

[0317] In one implementation, such as Figure 12 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.

[0318] Furthermore, such as Figures 12 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 water tank 13 and the kettle body 21 supply water to the water inlet 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, in order 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.

[0319] 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.

[0320] 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.

[0321] 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.

[0322] In one embodiment, the main unit 1 further includes a high water level detection mechanism. When the detachable 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 detachable 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 configure a corresponding high water level detection mechanism on the detachable kettle 2, which simplifies the structure of the detachable kettle 2 and reduces processing costs.

[0323] 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.

[0324] In one embodiment, when the detachable 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 detachable 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 detachable kettle 2 are replenished separately and simultaneously, resulting in a shorter replenishment time.

[0325] Furthermore, such as Figure 9 and Figure 12 As shown, when the detachable 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. This simplifies the structure of the kettle body 21 and also simplifies the pipeline connection between the detachable kettle 2 and the main unit 1.

[0326] Furthermore, such as Figure 12 and Figure 13 As shown, when the detachable kettle 2 is connected to the main unit 1 and the water purification device 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.

[0327] It should be understood that during the process of replenishing water to the water tank 13 and the detachable 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 level in the water tank and the kettle body to reach equilibrium as soon as possible, thereby increasing the accuracy of water level detection.

[0328] In one implementation, such as Figure 13 and Figure 18As shown, the water purification device 100 further includes a water collection member 18, and the water purification tank 13 and the detachable kettle 2 are respectively connected to the water collection member 18. When the water purification device 100 starts to produce water, the purified water enters the water purification tank 13 and the detachable kettle 2 respectively through the water collection member 18. When the water purification device 100 starts to supply water, the water purification tank 13 and the detachable kettle 2 supply water outward respectively through the water collection member 18. In this solution, by configuring the water collection member 18, the connection of the water inlet and outlet waterways of both the water purification tank 13 and the detachable kettle 2 is realized, which can reduce the number of pipelines and pipeline joints, simplify the pipeline design, and further can reduce the risk of pipeline blockage and the probability of pipeline joint leakage to a certain extent.

[0329] Further, as Figure 3 , Figure 13 and Figure 16 shown, the water purification tank 13 is provided with a tank connection port 132, and the detachable kettle 2 is provided with a kettle body connection port 216. The water collection member 18 is respectively connected to the tank connection port 132 and the kettle body connection port 216; the purified water flows into or out of the water purification tank 13 through the tank connection port 132, and the purified water flows into or out of the detachable kettle 2 through the kettle body connection port 216. Specifically, the water purification tank 13 cooperates with the water collection member 18 through the tank connection port 132 to realize the water inlet and outlet of the water purification tank 13, and the detachable kettle 2 cooperates with the water collection member 18 through the kettle body connection port 216 to realize the water inlet and outlet of the detachable kettle 2. There are few openings on the water purification tank 13 and the detachable kettle 2, few pipelines are supporting the water purification tank 13, and few pipelines are supporting the detachable kettle 2, which is beneficial to simplify the pipeline design of the water purification device 100.

[0330] Further, as Figure 13 , Figure 16 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 tank connection port 132 through a first pipeline 191, and the second connection port 182 is connected to the kettle body connection port 216 through a second pipeline 192. Of course, if the distance between the water collection member 18 and the tank connection port 132 or the kettle body connection port 216 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 tank connection port 132, or the first connection port 181 is directly connected to the low water level detection box 151 supporting the water purification tank 13; the second connection port 182 is directly connected to the attachment docking module 222 of the detachable kettle 2.

[0331] In an embodiment, as Figure 16 and Figure 18As shown, the water manifold 18 also has a third connection port 183 and a fourth connection port 184. The third connection port 183 is connected to the purified water outlet of the filter element assembly 171, and the fourth connection port 184 is used to supply water to the water supply port 14 of the water purification device 100. In this way, the water manifold 18 can achieve water circuit connection with the water tank 13, the detachable kettle 2, the filter element assembly 171, and the water supply port 14 through the four connection ports. The water manifold 18 has a simple structure, requiring only four water circuit connections, thereby reducing the number of pipes and pipe joints.

[0332] Furthermore, such as Figure 17 As shown, the main unit 1 is equipped with a second pump body 162. Under the power provided by the second pump body 162, raw water enters the filter element assembly 171, is purified by the filter element assembly 171, and is then discharged. 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.

[0333] In one embodiment, the filter element assembly 171 has a purified water outlet (not shown in the figure), and the water collection component 18 is located below the purified water outlet. On the one hand, the empty space below the filter element assembly 171 is used to accommodate the water collection component 18, minimizing changes to the placement of other components in the main unit 1. On the other hand, the distance between the water collection component 18 and the filter element assembly 171 can be shortened, which helps to reduce the number of pipes, thereby reducing the risk of pipe blockage and the probability of water leakage at pipe joints. 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 a booster pump or tap water. When the purified water tank and the kettle are bottom-inlet, it helps the water level in the purified water tank and the kettle to reach equilibrium as soon as possible, thereby increasing the accuracy of water level detection.

[0334] 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.

[0335] In one implementation, such as Figure 12 , Figure 13 and Figure 16As shown, the tank body connection port 132 of the water purifier 13, the kettle body connection port 216 of the detachable kettle 2, and the water collection component 18 are distributed sequentially 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 detachable 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 detachable kettle 2 supply water to the outside through the water supply port 14, if the water level in the water purifier 13 and the detachable 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, and when the user takes hot water, it can avoid steam spraying at the 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.

[0336] In one implementation, such as Figure 12 and Figure 13 As shown, the water purification tank 13 is located above the water collection component 18. The body connection port 216 of the detachable kettle 2, the body connection port 132 of the water purification tank 13, and the water collection component 18 are distributed sequentially in the left and right directions of the water purification equipment 100, which facilitates the arrangement of pipes.

[0337] Furthermore, such as Figure 13 As shown, the water purification device 100 includes a main housing 12, a water inlet 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 water inlet 14 in the front-to-back direction, thereby shortening the length of the third pipe 193 used to discharge water from the water collection component 18.

[0338] Furthermore, such as Figure 16 and Figure 18 As shown, the water collection component 18 has a fourth connection port 184 on the first side wall 1851 facing the detachable water bottle 2. 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 water supply port 14 in the front-back direction, thereby shortening the length of the third pipe 193.

[0339] Furthermore, such as Figure 13 , Figure 16 and Figure 18As shown, the first sidewall 1851 is provided with a first connection port 181, which is connected to the tank communication 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 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.

[0340] Furthermore, such as Figure 13 , Figure 16 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.

[0341] 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.

[0342] 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.

[0343] In one implementation, such as Figure 16 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 detachable kettle 2 supply water to the water supply port 14 respectively.

[0344] 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.

[0345] Furthermore, such as Figure 16 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.

[0346] Furthermore, such as Figure 16 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 detachable kettle 2, and the outlet end of the third pipe 193 is set close to the horizontal box 1514, which is reasonable and compact.

[0347] 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.

[0348] In one implementation, such as Figure 16 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 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 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 water supply port 14.

[0349] Furthermore, such as Figure 16 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.

[0350] Furthermore, such as Figure 16 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 water purification equipment 100 pipeline needs to be drained first. If the water supply port 14 has a water outflow failure, it can be manually drained through the drain component 173 to ensure that the repair work can be carried out smoothly.

[0351] In one implementation, such as Figure 16 and Figure 18 As shown, the water manifold 18 has a second connection port 182 on its second side wall 1852 away from the water supply port 14. The second connection port 182 is connected to the kettle body connection port 216 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.

[0352] Furthermore, such as Figure 16 As shown, the second pipe 192 extends in the horizontal plane. Specifically, the main unit 1 connects to the attachment module 222 of the detachable kettle 2 via the expansion function module 11, and sets the input end of the main unit water circuit connection element 111 of the 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.

[0353] In one implementation, such as Figure 18 and Figure 19 As 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 and the detachable kettle 2. 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 purified water provided by the filter element assembly 171 is introduced through the third connection port 183, the first connection port 181 supplies water to the purified water tank 13, and the second connection port 182 supplies water to the detachable 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 second connection port 182.

[0354] 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 detachable water jug ​​2, with the purified water tank 13 located inside the main housing 12 and the detachable water jug ​​2 exposed, the ambient temperatures of the purified water tank 13 and the detachable 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 detachable 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 detachable water jug ​​2. If only an NTC element is installed in the purified water tank 13, it will result in... Currently, inaccurate water temperature detection leads to either excessively high water temperature causing steam jets or excessively low water temperature, failing to meet user needs. In this solution, 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 detachable 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 improves the accuracy of temperature detection and avoids problems such as excessively high steam jets or excessively low water temperature in the heating element 172.

[0355] In one implementation, such as Figure 18 and Figure 19 As 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 flow guiding groove 1861 is low, the water entering from the third connection port 183 can quickly enter the flow guiding groove 1861, and then be discharged through the first connection port 181 and the second connection port 182 respectively; when the water purifier 100 in the first working mode starts supplying water, the water in the water tank 13 enters the flow guiding groove 1861 through the first connection port 181, and the water in the detachable kettle 2 enters the flow guiding groove 1861 through the second connection port 182. The water in the flow guiding 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.

[0356] Furthermore, such as Figure 18 and Figure 19As 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 detachable kettle 2. 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 purifier 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.

[0357] 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.

[0358] 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.

[0359] In one embodiment, the volume of the water storage cavity 186 is greater than or equal to 18 cm3, maximizing the use of the empty internal space at the bottom of the purified water outlet of the filter element assembly 171, and increasing the volume of the water storage cavity 186 as much as possible to avoid the first pump body 161 from being pumped dry.

[0360] In one implementation, such as Figure 12 and Figure 16As shown, when the detachable 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 detachable 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.

[0361] In one implementation, such as Figure 1 As shown, the main unit 1 also includes a raw water tank 1010. The raw water provided by the raw water tank 1010 is purified by the filter assembly 171 to form clean water, which is then provided to the clean water tank 13 and the detachable kettle 2. One of the raw water tank 1010 and the detachable kettle 2 is located on the left side of the main unit housing 12, and the other is located on the right side of the main unit housing 12. This is to avoid the water purifier 100 being too large in the front-to-back direction, which would limit its application scenarios due to the width of the countertop. Of course, the main unit 1 can also omit the raw water tank 1010 and be directly connected to the municipal tap water. Furthermore, the raw water tank 1010 and the detachable kettle 2 are symmetrically arranged about the main unit housing 12, which facilitates shorter operating distances for the components of the main unit 1 and is more aesthetically pleasing.

[0362] In one embodiment, the kettle body 21 is also provided with a spout 218 and a handle 219, the spout 218 being used to pour water and the handle 219 being used for the user to hold.
