The multifunctional water purifier of the present application will be described in detail below according to Figures 1 to 19.

[0049] In the present embodiment, as shown in Figures 1, 10 and 16, the multifunctional water purifier 100 comprises a main machine 1 and a functional water machine 4, the main machine 1 comprises a purified water tank 13 for storing purified water, and a water collecting member 18, the functional water machine 4 is detachably connected to the main machine 1, the functional water machine 4 comprises a functional water tank 41, the main machine 1 can be provided with a filter core assembly 171 for purifying raw water to form purified water to supply purified water. Of course, the main machine 1 can also not be provided with the filter core assembly 171, and the main machine 1 can store the pure water or mineral water provided by the user and considered clean by the user. When the functional water machine 4 is connected to the main machine 1, the functional water tank 41 and the purified water tank 13 are respectively connected to the water collecting member 18; wherein when the purified water tank 13 needs to be replenished, the purified water is distributed to the purified water tank 13 through the water collecting member 18; when the functional water tank 41 needs to be replenished, the purified water is distributed to the functional water tank 41 through the water collecting member 18.

[0050] In the technical solution, the multifunctional water purifier 100 is configured with the functional water machine 4, so that the user can directly use the purified water through the main machine 1 and use the functional water through the functional water machine 4, and the function is more abundant. In addition, the main machine 1 supplies water for the functional water machine 4, so that part of the structure of the functional water machine 4 is saved, the integration effect is good, and the cost is low. In addition, the multifunctional water purifier 100 is also configured with the water collecting piece 18. By configuring the water collecting piece 18, the water inlet waterway of the purified water tank 13 is connected, and the water inlet waterway of the functional water machine 4 is connected, so that the number of pipelines and the number of pipeline joints can be reduced, the pipeline design is simplified, and the risk of pipeline blockage and the probability of pipeline joint leakage can be reduced to a certain extent.

[0051] In an embodiment, as shown in FIGS. 10 and 17, when the multifunctional water purifier 100 is not in the water production state and the functional water tank 41 needs to be replenished with water, the purified water in the purified water tank 13 is distributed to the functional water tank 41 through the water collecting piece 18, so that the functional water tank 41 can be timely replenished with water. In addition, when the water level in the purified water tank 13 decreases to a low water level, the multifunctional water purifier 100 starts water production, and the purified water produced by the multifunctional water purifier 100 first enters the water collecting piece 18, and then timely replenishes the purified water tank 13 with purified water through the water collecting piece 18.

[0052] Further, as shown in FIGS. 10 and 17, the multifunctional water purifier 100 further comprises a filter element assembly 171. When the multifunctional water purifier 100 starts water production, the filter element assembly 171 works to purify raw water to produce purified water. In addition, when the multifunctional water purifier 100 is in the water production state and the functional water tank 41 needs to be replenished with water, since the purified water tank 13 is in communication with the water collecting piece 18, the purified water in the purified water tank 18 is drawn into the water collecting piece 18, and at the same time, the purified water produced by the filter element assembly 171 also enters the water collecting piece 18. The two routes of purified water converge in the water collecting piece 18, that is, the purified water in the purified water tank 13 and the purified water produced by the filter element assembly 171 converge in the water collecting piece 18, and are distributed to the functional water tank 41 through the water collecting piece 18, so that the functional water tank 41 can be quickly replenished with water.

[0053] Further, as shown in FIG. 10, the functional water machine 4 is also provided with a water replenishment pump 44. Under the power provided by the water replenishment pump 44, the purified water in the main machine 1 is distributed to the functional water tank 41 through the water collecting piece 18.

[0054] In an embodiment, the number of functional water machines 4 is at least two (not shown in the figure), such as two, three, etc. Due to the size limitation of the main machine 1, the number of functional water machines 4 is preferably one or two, and different functional water machines can be configured according to the needs, and the functions are diversified. When the functional water machine 4 is connected to the main machine 1, all the functional water machines 4 are respectively connected to the water collecting member 18, and the water collecting member 18 respectively allocates water to each functional water machine 4. The connection of the water inlet path of each functional water machine 4 through the water collecting member 18 can reduce the number of pipelines and the number of pipeline joints.

[0055] In an embodiment, as shown in FIGS. 1 and 10, when the functional water machine 4 is connected to the main machine 1, the functional water machine 4 is connected to the main machine 1 in circuit, and the circuit connection of the two can be used to transmit signals, or the main machine 1 can supply power to the functional water machine 4, or both. Of course, the functional water machine 4 can also be separately provided with an external plug to achieve power supply.

[0056] In an embodiment, the functional water machine 4 is an ice maker, an ice water machine, a bubble water machine, a tea boiler, a tea maker, or a coffee machine, which can be selectively matched according to actual needs, and the functions are diversified. As shown in FIGS. 1 and 10, the functional water machine 4 includes a functional water supply port 42 for automatically dispensing water outwardly. Specifically, the functional water machine 4 further includes a water supply pump 45, and under the power provided by the water supply pump 45, the water in the functional water tank 41 flows to the functional water supply port 42 and is dispensed to the user through the functional water supply port 42.

[0057] In an embodiment, as shown in FIGS. 1, 10 and 11, the main machine 1 further includes a first expansion function module 11, and the functional water machine 4 is provided with a first attachment docking module 43. The first expansion function module 11 cooperates with the first attachment docking module 43 to enable the functional water machine 4 to be detachably connected to the main machine 1.

[0058] Further, as shown in FIGS. 1, 10 and 11, the first expansion function module 11 includes a first main machine water path docking element 111, and the first attachment docking module 43 includes a first attachment water path docking element 431. The multifunctional water purifier 100 has at least two working modes, which can be a multifunctional working mode and a separate working mode. When the multifunctional water purifier 100 is in the multifunctional working mode, the functional water machine 4 is installed on the first expansion function module 11, the first main machine water path docking element 111 is docked with the first attachment water path docking element 431, so that the main machine 1 supplies water to the functional water machine 4, and the main machine 1 and the functional water machine 4 are used in cooperation, and the functional water machine 4 can use the purified water provided by the main machine 1. When the multifunctional water purifier 100 is in the separate working mode, the functional water machine 4 is not installed on the first expansion function module 11, and the main machine 1 works independently and purifies through the filter element assembly 171 of the main machine 1 to provide purified water for drinking.

[0059] Through the above setting mode, the user can first realize the demand of directly drinking pure water through the host 1; secondly, through the first expansion function module 11 connecting the functional water machine 4, the host 1 can supply water for the functional water machine 4, saving part of the structure of the functional water machine 4, good integration effect and low cost.

[0060] Further, as shown in FIG. 10 and FIG. 11, the first expansion function module 11 further comprises a first host electrical docking element 112, and the first attachment docking module 43 further comprises a first attachment electrical docking element 432. When the multifunctional water purifier 100 is in the multifunctional mode, the first host electrical docking element 112 is docked with the first attachment electrical docking element 432, and the host 1 supplies power for the functional water machine 4 and / or the host 1 and the functional water machine 4 perform signal interaction.

[0061] In an embodiment, as shown in FIG. 10 and FIG. 11, the first host waterway docking element 111 and the first attachment waterway docking element 431 constitute a water valve assembly. When the first host waterway docking element 111 is docked with the first attachment waterway docking element 431, the first host waterway docking element 111 and the first attachment waterway docking element 431 are respectively in an open state, and the host 1 and the functional water machine 4 can realize fluid circulation through the first host waterway docking element 111 and the first attachment waterway docking element 431. When the first attachment waterway docking element 431 is separated from the first host waterway docking element 111, the first host waterway docking element 111 is in a closed state to prevent water in the host 1 from flowing out of the first host waterway docking element 111, and the first attachment waterway docking element 431 is in a closed state to prevent water in the functional water machine 4 from flowing out of the first attachment waterway docking element 431.

[0062] In addition, one of the first host electrical docking element 112 and the first attachment electrical docking element 432 is a female end of a coupler, and the other is a male end of the coupler, and the electrical connection is achieved by plugging the female end of the coupler with the male end of the coupler. Preferably, as shown in FIGS. 10 and 11, the first host electrical docking element 112 is the female end of the coupler, and the first attachment electrical docking element 432 is the male end of the coupler, which facilitates docking and avoids the need to make a relatively complex waterproof structure for the first host electrical docking element 112. Specifically, the first host electrical docking element 112 includes at least one of a host power supply terminal, a host detection terminal, and a host signal terminal, wherein the host power supply terminal is used to provide power for the functional water machine 4, the host detection terminal is used to determine whether the functional water machine 4 is docked, and the host signal terminal is used to send information to the functional water machine 4 and / or receive information sent by the functional water machine 4. In actual product application, different types and different numbers of terminals are set according to product requirements. For example, in order to facilitate user installation, the first host electrical docking element 112 includes a host power supply terminal, so that the functional water machine 4 does not need to be provided with an additional socket in the installation scenario. For example, in order to save costs and facilitate user operation on the same user interface, the first host electrical docking element 112 includes a host signal terminal.

[0063] In an embodiment, the first expansion function module 11 is removably installed on the host 1. When in a single working mode, the first expansion function module 11 is in a retracted state, and at least the first host waterway docking element 111 and the first host electrical docking element 112 in the first expansion function module 11 are located inside the host 1 to improve the aesthetics of the entire machine. Preferably, when in a single working mode, the first expansion function module 11 is entirely retracted into the water supply host 1, which embodies the overall aesthetics, avoids the problem of bumps during transportation and use, and finally prevents dust and water. As shown in FIG. 11, when in a multifunctional working mode, at least the first host waterway docking element 111 and the first host electrical docking element 112 in the first expansion function module 11 are located outside the host 1 to enable the functional water machine 4 to be connected to the first expansion function module 11 smoothly. Preferably, when the multifunctional water purifier 100 is in a multifunctional working mode, at least the first host electrical docking element 112 and the first host waterway docking element 111 in the first expansion function module 11 are installed on the host 1 in a bare state to install the functional water machine 4.

[0064] In an embodiment, the first expansion function module 11 is arranged at the lower part of one side of the host 1, and the bottom of the first expansion function module 11 can abut against the installation platform. After the functional water machine 4 is docked, the weight of the functional water machine 4 applied to the first expansion function module 11 can be avoided as much as possible, or even not borne, thereby ensuring that the first expansion function module 11 has a small position deformation amount and high docking accuracy during long-term use.

[0065] In another embodiment, as shown in FIG. 11, the first extended function module 11 is arranged on one side wall of the main machine 1 and faces the functional water machine 4. Specifically, the first extended function module 11 is arranged on the lower part of one side of the main machine 1, and the functional water machine 4 is plugged into the first host machine electrical interface element 112 and the first host machine waterway interface element 111 of the first extended function module 11 in the left-right direction. In this embodiment, it is worth noting that the first extended function module 11 is fixedly arranged on the main machine 1. The protruding direction of the first host machine electrical interface element 112 is parallel to the docking direction of the functional water machine 4, and the protruding direction of the first host machine electrical interface element 112 is parallel to the bottom surface of the main machine 1, and the extension direction of the first host machine waterway interface element 111 is parallel to the bottom surface, so as to plug the functional water machine 4 laterally. The functional water machine 4 is docked with the main machine 1 in the up-down direction, the protruding direction of the first host machine electrical interface element 112 is perpendicular to the bottom surface of the main machine 1, and the extension direction of the first host machine waterway interface element 111 is perpendicular to the bottom surface, so as to avoid the problem of movement of the functional water machine 4 caused by vibration of the second pump body 162 (usually a booster pump for pumping water in the filter cartridge assembly 171) during operation of the whole machine, as shown in FIG. 14.

[0066] In an embodiment, as shown in FIG. 11, for the accommodation of the first extended function module 11, the main machine shell 12 of the main machine 1 is provided with a first accommodating cavity 122, which can penetrate the side wall of the main machine shell 12, so as to facilitate the back-and-forth switching of the relative positions of the first extended function module 11 in the single working mode and the multi-functional working mode.

[0067] Further, for the convenience requirement of back-and-forth switching of the relative positions of the first extended function module 11, a slide rail (not shown in the figure) is arranged in the first accommodating cavity 122, and a slide groove (not shown in the figure) is arranged on the first extended function module 11, and the slide rail and the slide groove are matched with each other, so that the first extended function module 11 is slidably arranged on the main machine 1. Of course, the installation positions of the slide rail and the slide groove can also be replaced, and the essence is to facilitate installation. Of course, the wedge-shaped block and the slot body cooperation pulling mode, the cylinder pushing and retracting pulling mode can also be used, and the essence is to meet the characteristics of low cost and small installation space ratio.

[0068] In an embodiment, as shown in FIG. 12, the first extension function module 11 is accommodatively installed on the main machine shell 12 of the main machine 1, and the main machine shell 12 further comprises a first decorative cover 121, which covers the first extension function module 11 when the multifunctional water purifier 100 is in a single working mode. When the first extension function module 11 is accommodated in the first accommodating cavity 122, the active part of the first extension function module 11 is still exposed to the air due to the design requirements of the assembly space. For users with high cleanliness requirements, the first extension function module 11 can be completely sealed by the first decorative cover 121 after the covering action, thereby achieving better cleanliness maintenance effect and providing multiple operation requirements for users.

[0069] In the embodiment in which the first extension function module 11 is installed on the main machine 1 and accommodated in the first accommodating cavity 122, the first decorative cover 121 can be inserted into the first accommodating cavity 122 to realize the covering action of the first extension function module 11.

[0070] In an embodiment, as shown in FIGS. 11 and 12, the first extension function module 11 comprises a first shell 113, and a first main machine electrical interface element 112 (such as a coupler) and a first main machine waterway interface element 111 (such as a water stop valve) are arranged on the first shell 113. Specifically, the active part of the first main machine electrical interface element 112 and the active part of the first main machine waterway interface element 111 are arranged on the upper surface of the first shell 113. During the interfacing process of the functional water machine 4 and the main machine 1, the interfacing action is downward along the vertical direction and adheres to the side wall of the main machine 1, which is simple to operate.

[0071] Further, the first main machine electrical interface element 112 comprises at least one electrical guide. Further, as shown in FIG. 11, at least one first waterproof element 114 is arranged on the first shell 113, and the first waterproof element 114 is arranged corresponding to the electrical guide, and the at least one electrical guide is located below the corresponding first waterproof element 114. Preferably, the first waterproof element 114 is an openable and closable waterproof silica gel sheet. The waterproof silica gel sheet is provided with an opening in a cross shape, a rice character shape or the like. During the interfacing process, the first attachment electrical interface element 432 extrudes the opening of the waterproof silica gel sheet and is interfaced with the electrical guide after passing through.

[0072] In an embodiment, as shown in FIGS. 1 and 10, the multifunctional water purifier 100 further comprises a kettle 2 to increase the water storage capacity of the multifunctional water purifier 100. When the kettle 2 is connected with the main machine 1, the kettle 2 is connected with the water collecting element 18, and the purified water flows into or out of the kettle 2 through the water collecting element 18. In this way, the water inlet and outlet waterways of the kettle 2 are integrated on the water collecting element 18, further reducing the number of pipelines and pipeline joints required to be arranged in the main machine 1.

[0073] Further, when the kettle 2 is connected with the main machine 1, the circuit of the kettle 2 and the main machine 1 is connected, the circuit connection of the kettle 2 and the main machine 1 can be used to transmit signals, the main machine 1 can also supply power to the kettle 2, and of course it can be used to transmit signals and supply power. Of course, the kettle 2 can also be provided with an external plug to achieve power supply.

[0074] In an embodiment, the kettle 2 includes a kettle body 21 and a kettle seat 22 connected detachably, the kettle body 21 is not directly connected with the main machine 1, facilitating quick removal or installation of the kettle body 21, convenient to take, easy and labor-saving operation, and the user can directly take water by removing the kettle body 21. In this way, the function is rich and the required amount of water can be quickly taken according to the water taking demand.

[0075] In an embodiment, as shown in FIG. 1, the kettle seat 22 is fixedly connected with the main machine 1, and the kettle seat 22 cannot be removed, which can simplify the assembly structure of the kettle seat 22 and the main machine 1 and simplify the assembly process.

[0076] Further, as shown in FIG. 1, the main machine 1 includes a main machine base 123, and the kettle seat 22 is fixed to the main machine base 123. The main machine base 123 is used to install the kettle seat 22 and can also be used to form the bottom outer contour structure of the kettle seat 22. The kettle seat 22 does not need to be additionally provided with a corresponding bottom plate structure, which is conducive to simplifying the structure of the kettle seat 22.

[0077] Further, as shown in FIG. 1 and FIG. 10, a flow collecting component 1011 is arranged between the bottom of the kettle seat 22 and the main machine base 123. Raw water is supplied to the filter core assembly 171 in the main machine 1 through the flow collecting component 1011, and waste water generated in the purification process of the filter core assembly 171 is discharged through the flow collecting component 1011. Specifically, the flow collecting component 1011 is provided with a raw water inlet 10111, a raw water outlet 10112, a waste water inlet 10113 and a waste water outlet 10114. The flow collecting component 1011 is provided with a first flow channel (not shown in the figure) for connecting the raw water inlet 10111 and the raw water outlet 10112, and a second flow channel (not shown in the figure) for connecting the waste water inlet 10113 and the waste water outlet 10114. Since the multifunctional water purifier 100 is simultaneously provided with the functional water machine 4 and the kettle 2, in order to avoid the size of the multifunctional water purifier 100 being too large, the multifunctional water purifier 100 does not configure a raw water tank. The raw water inlet 10111 of the flow collecting component 1011 is connected with the municipal tap water pipe, and the raw water outlet 10112 is connected with the inlet end of the filter core assembly 171 to supply raw water to the main machine 1. Waste water is generated in the purification process of the filter core assembly 171. The waste water discharge outlet of the filter core assembly 171 is connected with the waste water inlet 10113 of the flow collecting component 1011, and then the waste water is discharged through the waste water outlet 10114.

[0078] In another embodiment, the kettle seat 22 is detachably connected with the main machine 1. If the pipeline or component in the kettle seat 22 fails, the kettle seat 22 can be removed for timely maintenance or replacement. The detachable connection of the kettle seat 22 with the main machine 1 can also meet more user needs. For example, when the user does not want to use the kettle 2 or the overall space is insufficient, the kettle seat 22 and the kettle body 21 can be removed together for storage, avoiding the accumulation of dust and dirt in the kettle seat 22 due to the removal of only the kettle body 21, the entry of the dirt from the connection between the kettle seat 22 and the kettle body 21 into the water purification pipeline of the main machine, and the pollution of the water purification pipeline. In addition, the detachable kettle seat 22 can also avoid occupying space.

[0079] In an embodiment, the connection mode of the kettle body 21 and the kettle seat 22 includes clamping, buckling or adsorption connection.

[0080] Further, as shown in FIGS. 1 to 4, the kettle body 21 is clamped downward on the kettle seat 22, so that the kettle body 21 and the kettle seat 22 are detachably connected. In this way, under the gravity of the kettle body 21 itself, the kettle body 21 can stably maintain the clamped state with the kettle seat 22. Of course, the clamping direction of the kettle body 21 and the kettle seat 22 is not limited to this, and the kettle body 21 can also be clamped on the kettle seat 22 in the left-right direction or the front-rear direction.

[0081] Further, as shown in FIG. 2, the circumferential side wall of the kettle body 21 extends downward to form an extension wall 211; and the kettle body bottom wall 212 of the kettle body 21 cooperates with the extension wall 211 to form a clamping groove 213. As shown in FIG. 4, the kettle seat 22 is provided with a clamping protrusion 22111, and the clamping groove 213 is clamped with the clamping protrusion 22111 to realize the assembly of the kettle body 21 and the kettle seat 22. Specifically, since the kettle body 21 and the kettle seat 22 need to be connected with the water pipeline, and the kettle body 21 is clamped downward on the kettle seat 22, the bottom of the kettle body 21 will be provided with a structure for water pipeline connection of the kettle seat 22, resulting in the surface of the kettle body bottom wall 212 being uneven. In the present scheme, the extension wall 211 is provided on one hand to be clamped with the clamping protrusion 22111, and on the other hand to cover the structure provided at the bottom of the kettle body 21 for water pipeline connection of the kettle seat 22, thereby improving the appearance of the kettle body 21 after being removed. In addition, the bottom wall of the extension wall 211 also serves as a support structure to facilitate the user to place the kettle body 21 directly on the table top after being removed.

[0082] Further, as shown in FIGS. 3 and 4, the kettle seat 22 is provided with an outer shell 2211, which forms the outer contour of the circumferential side and the top of the kettle seat 22 to improve the appearance. The top wall of the outer shell 2211 is provided with a support table 22112 and a clamping protrusion 22111. The kettle body 21 is clamped with the outer shell 2211, and at the same time, the bottom surface of the extension wall 211 abuts against the top surface of the support table 22112, which is conducive to the stable support of the kettle body 21 by the kettle seat 22.

[0083] In an embodiment, as shown in FIG. 3 and FIG. 4, the kettle 2 comprises a detachably connected kettle body 21 and kettle base 22, and further comprises a lower water valve assembly 23. When the kettle body 21 is connected to the kettle base 22, the lower water valve assembly 23 is in an open state, and the kettle body 21 and the kettle base 22 are in fluid communication through the lower water valve assembly 23, so that the main machine 1 can supply water to the kettle body 21 through the kettle base 22; when the kettle body 21 is separated from the kettle base 22, the lower water valve assembly 23 is in a closed state to avoid water leakage of the kettle body 21 and the kettle base 22.

[0084] Specifically, as shown in FIG. 3, the lower water valve assembly 23 comprises a kettle body valve group 231 and a kettle base valve group 232, the kettle body valve group 231 comprises a first valve body 2311 and a first valve core 2312, the kettle base valve group 232 comprises a second valve body 2321 and a second valve core 2322, the kettle body 21 is provided with a first annular column 217, the kettle base 22 is provided with a second annular column 227, the first valve body 2311 is installed on the first annular column 217, and the second valve body 2321 is installed on the second annular column 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. Taking the specific structure shown in FIG. 3 that the first valve core 2312 is located above the second valve core 2322 as an example, when the kettle body 21 is connected to the kettle base 22, the first valve core 2312 is located at the corresponding upper limit position, and the second valve core 2322 is located at the corresponding lower limit position, the lower water valve assembly 23 is in an open state, and the water in the kettle base 22 can flow into the kettle body 21 through the lower water valve assembly 23; when the kettle body 21 is separated from the kettle base 22, the first valve core 2312 moves downward to the corresponding lower limit position, the first valve core 2312 cooperates with the first valve body 2311 to avoid water in the kettle body 21 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 avoid water in the kettle base 22 flowing out from the second valve body 2321, at this time, the lower water valve assembly 23 is in a closed state.

[0085] In an embodiment, as shown in FIG. 8, the main machine 1 further comprises a second expansion function module (not shown in the figure), and the kettle base 22 is provided with a second attachment docking module 222. The second expansion function module cooperates with the second attachment docking module 222 to detachably connect the kettle base 22 with the main machine 1.

[0086] Further, as shown in FIG. 8, the second expansion function module comprises a second host waterway docking element, and the second attachment docking module 222 comprises a second attachment waterway docking element 2221. The multifunctional water purifier 100 has at least two working modes, specifically, a multifunctional working mode and a single working mode. When the multifunctional water purifier 100 is in the multifunctional working mode, the kettle 2 is installed on the second expansion function module, the second host waterway docking element is docked with the second attachment waterway docking element 2221, so that the host 1 supplies water for the kettle 2, the host 1 and the kettle 2 are used in cooperation, and the kettle 2 can use the purified water provided by the host 1. When the multifunctional water purifier 100 is in the single working mode, the kettle 2 is not installed on the second expansion function module, and the host 1 works independently and purifies through the filter assembly 171 of the host 1 to provide purified water for drinking.

[0087] Through the above setting mode, the user can first realize the demand of directly drinking purified water through the host 1; secondly, the kettle 2 is connected through the second expansion function module, and the host 1 can supply water for the kettle 2 on the basis of the host 1, so that part of the structure of the kettle 2 is saved, the integration effect is good, and the cost is low.

[0088] Further, as shown in FIG. 8, the second expansion function module further comprises a second host electrical docking element, and the second attachment docking module 222 further comprises a second attachment electrical docking element 2222. When the multifunctional water purifier 100 is in the multifunctional mode, the second host electrical docking element is docked with the second attachment electrical docking element 2222, the host 1 supplies power for the kettle 2 and / or the host 1 and the kettle 2 perform signal interaction.

[0089] The first expansion function module 11 in the scheme and the second expansion function module have the same or substantially the same structure, the first attachment docking module 43 and the second attachment docking module 222 have the same or substantially the same structure, and the structure, assembly relationship and principle of the second expansion function module and the second attachment docking module 222 are described again as follows.

[0090] In an embodiment, as shown in FIG. 8, the second host waterway docking element and the second attachment waterway docking element 2221 constitute a water valve assembly, when the second host waterway docking element is docked with the second attachment waterway docking element 2221, the second host waterway docking element and the second attachment waterway docking element 2221 are respectively in an open state, the host 1 and the kettle 2 can realize fluid circulation through the second host waterway docking element and the second attachment waterway docking element 2221, when the second attachment waterway docking element 2221 is separated from the second host waterway docking element, the second host waterway docking element is in a closed state to prevent water in the host 1 from flowing out from the second host waterway docking element, and the second attachment waterway docking element 2221 is in a closed state to prevent water in the kettle 2 from flowing out from the second attachment waterway docking element 2221.

[0091] In addition, one of the second host electrical docking element and the second attachment electrical docking element 2222 is a female end of a coupler, and the other is a male end of the coupler, and the electrical connection is achieved by plugging the female end of the coupler with the male end of the coupler. Preferably, as shown in FIG. 8, the second host electrical docking element is the female end of the coupler, and the second attachment electrical docking element 2222 is the male end of the coupler, which facilitates docking and avoids the need to make a relatively complex waterproof structure for the second host electrical docking element. Specifically, the second host electrical docking element includes at least one of a host power supply terminal, a host detection terminal, and a host signal terminal, wherein the host power supply terminal is used to provide power for the kettle, the host detection terminal is used to determine whether the kettle is docked, and the host signal terminal is used to send information to the kettle and / or receive information sent by the kettle. In actual product application, different types and different numbers of terminals are set according to product requirements. For example, in order to facilitate user installation, the second host electrical docking element includes a host power supply terminal, so that a socket does not need to be provided for the kettle in the installation scenario. For example, in order to save costs and facilitate user operation on the same user interface, the second host electrical docking element includes a host signal terminal.

[0092] In an embodiment, the second expansion function module is accommodably installed on the host 1; when in a single working mode, the second expansion function module is in an accommodation state, and at least the second host waterway docking element and the second host electrical docking element in the second expansion function module are located in the host 1, so as to improve the aesthetics of the whole machine. Preferably, when in the single working mode, the second expansion function module is entirely accommodated in the water supply host 1, which embodies the overall aesthetics, avoids the problem of bumping during transportation and use, and finally prevents dust and water. When in a multifunctional working mode, at least the second host waterway docking element and the second host electrical docking element in the second expansion function module are located outside the host 1, so that the kettle 2 can be smoothly connected with the second expansion function module. Preferably, when the multifunctional water purifier 100 is in the multifunctional working mode, at least the second host electrical docking element and the second host waterway docking element in the second expansion function module are exposedly installed on the host 1, so as to install the kettle 2.

[0093] In an embodiment, the second expansion function module is arranged at the lower part of one side of the host 1, and the bottom of the second expansion function module can abut against the installation platform. After the kettle 2 is docked, the weight of the kettle 2 applied to the second expansion function module can be avoided as much as possible, and even the second expansion function module does not bear the weight of the kettle 2, so as to ensure that the position of the second expansion function module has a small deformation amount and has a high docking accuracy during long-term use. Specifically, the functional water machine 1 and the kettle 2 are arranged on the left and right sides of the host 1, respectively, so as to facilitate user use.

In this embodiment, it is worth noting that the second expansion function module is fixedly arranged on the main machine 1. The protruding direction of the second main machine electrical docking element is parallel to the docking direction of the kettle 2, and the protruding direction of the second main machine electrical docking element is parallel to the bottom surface of the main machine 1, and the extension direction of the second main machine waterway docking element is parallel to the bottom surface, so as to facilitate the lateral insertion of the kettle 2. The kettle 2 is docked with the main machine 1 in the up-down direction, the protruding direction of the second main machine electrical docking element is perpendicular to the bottom surface of the main machine 1, and the extension direction of the second main machine waterway docking element is perpendicular to the bottom surface, so as to avoid the problem of movement of the kettle 2 caused by vibration of the second pump body 162 (usually a booster pump for pumping water in the filter cartridge assembly 171) during operation of the whole machine, as shown in FIG. 14.

[0095] In an embodiment, for the accommodation of the second expansion function module, a second accommodating cavity (not shown in the figure) is arranged on the main machine shell 12 of the main machine 1, which can penetrate the side wall of the main machine shell 12, so as to facilitate the back-and-forth switching of the relative positions of the second expansion function module in the single working mode and the multi-functional working mode.

[0096] Further, for the convenience requirement of back-and-forth switching of the relative positions of the second expansion function module, a sliding rail (not shown in the figure) is arranged in the second accommodating cavity, and a sliding groove (not shown in the figure) is arranged on the second expansion function module, and the sliding rail and the sliding groove are matched with each other, so that the second expansion function module is slidably arranged on the main machine 1. Of course, the installation positions of the sliding rail and the sliding groove can also be replaced, and the main purpose is to facilitate installation. Of course, the wedge-shaped block and the slot body cooperation pulling mode, the cylinder pushing and retracting pulling mode can also be used, and the main purpose is to meet the characteristics of low cost and small installation space ratio.

[0097] In an embodiment, the second expansion function module is accommodated and installed on the main machine shell 12 of the main machine 1, and the main machine shell 12 further comprises a second decorative cover (not shown in the figure), which covers the second expansion function module when the multi-functional water purifier 100 is in the single working mode. When the second expansion function module is accommodated in the second accommodating cavity, the active part of the second expansion function module is still exposed to the air due to the design requirement of the assembly space. For users with high cleanliness requirements, by arranging the second decorative cover, the active part of the second expansion function module can be completely sealed after the covering action, so as to achieve better cleanliness maintenance effect and provide multiple operation requirements for users.

[0098] In the embodiment in which the second expansion function module is installed on the main machine 1 and accommodated in the second accommodating cavity, the second decorative cover can be inserted into the second accommodating cavity to realize the covering action of the second expansion function module.

[0099] In an embodiment, the second expansion function module includes a second shell, and a second main machine electrical interface element (such as a coupler) and a second main machine waterway interface element (such as a water stop valve) are arranged on the second shell. Specifically, the active part of the second main machine electrical interface element and the active part of the second main machine waterway interface element are arranged on the upper surface of the second shell, and the docking action is along the vertical direction downward and close to the side wall of the main machine 1 during the docking process of the kettle 2 and the main machine 1, which is simple to operate.

[0100] Further, the second main machine electrical interface element includes at least one electrical guide. Further, at least one second waterproof element is arranged on the second shell, and the second waterproof element is arranged corresponding to the electrical guide, and the at least one electrical guide is located below the corresponding second waterproof element. Preferably, the second waterproof element is an open and closed waterproof silica gel sheet. The waterproof silica gel sheet is provided with an opening in a cross shape, a rice character shape or the like. During the docking process, the second attachment electrical interface element 2222 extrudes the opening of the waterproof silica gel sheet and is docked with the electrical guide after passing through.

[0101] In an embodiment, as shown in FIG. 10, the main machine 1 further includes a water purification tank 13, and the second main machine waterway interface element is in fluid communication with the water purification tank 13, so that the kettle body 21 is in communication with the water purification tank 13.

[0102] In an embodiment, as shown in FIG. 4, the kettle seat 22 includes a base 2212 and a support 2213, the support 2213 is installed above the base 2212, and the base 2212 and the support 2213 can be connected by fasteners (such as screws) or can be connected by buckling or the like. The second attachment interface module 222 is installed on the base 2212, and the kettle seat valve assembly 232 of the drain valve assembly 23 is installed on the support 2213, so that the kettle seat 22 is arranged in a split structure, which is convenient for processing.

[0103] Further, as shown in FIG. 4, FIG. 5 and FIG. 8, the upper surface of the base 2212 and the lower surface of the support 2213 form a containing space 2214. The kettle base 22 is further provided with an adapter 223 and a kettle control board 224, the adapter 223 is contained in the containing space 2214. The output end of the second attached electrical docking element 2222 is located in the containing space 2214 and is electrically connected with the input end of the adapter 223, the output end of the adapter 223 is electrically connected with the kettle control board 224, wherein the adapter 223 is used to convert alternating current into direct current to power the kettle control board 224, in addition, the main control board in the main machine 1 is connected with the signal line to the second main machine electrical docking element, at the same time the second attached electrical docking element 2222 is connected with the signal line to the kettle control board 224, so that the main machine 1 and the kettle 2 interact with signals.

[0104] Further, as shown in FIG. 5 and FIG. 6, the upper surface of the base 2212 is provided with a first recess 22121, the adapter 223 is at least partially clamped in the first recess 22121, so that when assembling the kettle 2, the adapter 223 is clamped in the first recess 22121 first, and then further connected (such as fixed by screws), in the present scheme, the first recess 22121 is provided, on the one hand, it can play a positioning role for the installation position of the adapter 223, on the other hand, it can preliminarily limit the movement of the adapter 223, which is convenient for assembly.

[0105] In an embodiment, as shown in FIG. 8 to FIG. 9, the lower surface of the base 2212 is concave towards the support 2213 to form a recessed part 22122. The input end of the second attached docking module 222 is located in the recessed part 22122, when the kettle base 22 is installed in the main machine 1, the second expansion function module is inserted in the recessed part 22122, so that the second expansion function module cooperates with the second attached docking module 222. In the present scheme, the recessed part 22122 is provided to accommodate the input end of the second attached docking module 222, avoiding the second attached docking module 222 protruding outside the base 2212, which can avoid the kettle base 22 being inconvenient to place after being removed, and can play a protective role for the second attached docking module 222 during carrying or using, avoiding the second attached docking module 222 being accidentally damaged.

[0106] Further, as shown in FIG. 8, the bottom of the recess 22122 and its side facing the main machine 1 are both open, and the second expansion function module is inserted into the recess 22122 in a downward direction, which facilitates stable docking of the second attachment docking module 222 and the second expansion function module under the action of the gravity of the kettle 2 itself. When the kettle seat 22 is disassembled, the kettle seat 22 moves upward to disengage from the main machine 1. Specifically, since the multifunctional water purifier 100 has a certain height, the space in the height of the application scenario of the multifunctional water purifier 100 is relatively sufficient. In the present scheme, the kettle seat 22 is disassembled in the up-down direction, fully utilizing the original space in the height of the application scenario, and can be applied to application scenarios with limited lateral space. Of course, the kettle seat 22 can also be disassembled from the main machine 1 in the left-right direction or the front-rear direction, which is suitable for application scenarios with sufficient lateral space.

[0107] In an embodiment, as shown in FIGS. 5 and 6, the lower surface of the base 2212 is recessed to form the recess 22122, and a protrusion 22123 is formed on the upper surface of the base 2212 at the same time. The adapter 223 is located on one side of the protrusion 22123. Further, one side wall of the protrusion 22123 constitutes one groove wall of the first groove 22121, and the adapter 223 abuts against the one side wall of the protrusion 22123, which is compact in arrangement and facilitates the miniaturization design of the base 2212. The kettle seat 22 is also provided with a first power line (not shown in the figure), which is used to electrically connect the output end of the second attachment electric docking element 2222 with the input end of the adapter 223. The base 2212 is also provided with a first threading hole 22124, which is used to thread the first power line, so as to facilitate the regular arrangement of the wiring. Preferably, at least one side of the first threading hole 22124 is open to facilitate threading.

[0108] Further, as shown in FIGS. 5 and 6, the first threading hole 22124 is arranged on the upper surface of the protrusion 22123. Specifically, the adapter 223 is located on one side of the protrusion 22123, and the output end of the second attachment electric docking element 2222 is located above the protrusion 22123. The first threading hole 22124 is located between the adapter 223 and the output end of the second attachment electric docking element 2222, which facilitates the shortening of the length of the first power line

[0109] In an embodiment, as shown in FIG. 8, one side outer wall of the bracket 2213 is provided with a second groove 22131, and the kettle control panel 224 is installed in the second groove 22131, which also protects the kettle control panel 224 from being scratched. The kettle control panel 224 is opposite to the output end of the adapter 223 to shorten the distance between the kettle control panel 224 and the output end of the adapter 223. The kettle seat 22 is also provided with a second power line (not shown in the figure), which is used to electrically connect the output end of the adapter 223 and the kettle control panel 224. The groove wall of the second groove 22131 is provided with a second threading hole 221311, which is used to thread the second power line, so as to make the wiring regular. Preferably, at least one side of the second threading hole 221311 is open to facilitate threading.

[0110] Further, as shown in FIGS. 5 and 8, in order to facilitate the threading of the first power line and the second power line, the first threading hole 22124 is located on one side of the adapter 223, and the second threading hole 221311 is located on the other side of the adapter 223, so as to avoid interference between the first power line and the second power line.

[0111] In an embodiment, as shown in FIGS. 5 and 7, the multifunctional water purifier 100 further comprises a locking element 31, which is movable between a locking position and an unlocking position. When the locking element 31 is in the locking position, the locking element 31 locks the kettle seat 22 to prevent the kettle seat 22 from being separated from the main machine 1. When the locking element 31 moves to the unlocking position, the locking element 31 is unlocked, and the kettle seat 22 can be separated from the main machine 1. Specifically, in the normal use state of the kettle 2, the kettle seat 22 does not need to be removed, and the kettle body 21 can be removed as needed to obtain drinking water. Since the kettle body 21 will exert a force on the kettle seat 22 when the kettle body 21 is installed or removed, in order to avoid the kettle seat 22 from being separated from the main machine 1 due to the force exerted by the kettle body 21, the locking element 31 is provided to lock the kettle seat 22, so as to ensure that the kettle seat 22 can be stably connected with the main machine 1.

[0112] Further, as shown in FIG. 5, the multifunctional water purifier 100 further comprises a resilient element 32, which is used to keep the locking element 31 in the locking position. When the external force applied to the locking element 31 is greater than the elastic force of the resilient element 32, the locking element 31 can move toward the unlocking position under the external force, the resilient element 32 is compressed, and the resilient element 32 thus stores energy. When the external force is removed, the resilient element 32 rebounds to release energy and applies a pushing force to the locking element 31 to reset the locking element 31 to the locking position. When the locking element 31 is in the locking position, the resilient element 32 exerts a force on the locking element 31, so that the locking element 31 can be stably in the locking position. Preferably, the resilient element 32 is a spring, which has a simple structure.

[0113] In an embodiment, as shown in FIG. 5, the locking element 31 is movably installed on the base 22. When the base 22 is in the connected state with the main machine 1 and the locking element 31 is in the locking position, the main machine 1 at least partially blocks the path of the locking element 31 moving in the first direction, and the main machine 1 can prevent the locking element 31 from moving in the first direction together with the base 22 to disengage from the main machine 1, thereby achieving locking; wherein the first direction is the moving direction of the base 22 when disengaging from the main machine 1. In a specific embodiment, the base 22 moves upward to disengage from the main machine 1, and the first direction is upward. The kettle body 21 is also lifted upward to be removed. By providing the locking element 31, the base 22 can be prevented from being lifted when the kettle body 21 is lifted upward.

[0114] Further, as shown in FIG. 9, when the base 22 is in the connected state with the main machine 1 and the locking element 31 is in the locking position, the locking element 31 abuts against the main machine 1 in the first direction. Through the restriction of the main machine 1 on the locking element 31, the base 22 cannot move in the first direction.

[0115] Further, as shown in FIG. 9, when the base 22 is in the connected state with the main machine 1 and the locking element 31 is in the locking position, the locking element 31 abuts against the second expansion function module in the first direction. Specifically, the main machine 1 is docked with the kettle 2 through the second expansion function module in the exposed state, and the locking element 31 can directly abut against the second expansion function module to achieve locking. No additional components need to be provided on the main machine 1 to abut against the locking element 31, which reduces the modification of the structure of the main machine 1 and reduces the cost. Of course, the cooperation relationship between the locking element 31 and the main machine 1 is not limited to this. For example, a locking slot (not shown in the figure) can be provided on the main machine 1, and the locking element 31 is inserted into the locking slot to achieve locking.

[0116] Further, as shown in FIG. 9, when the kettle seat 22 is connected to the main machine 1 and the locking element 31 is in the locking position, the locking element 31 at least partially extends into the recess 22122 and abuts against the second expansion function module in the first direction. In a specific embodiment, the kettle 2 is located on the right side of the main machine 1, when the kettle seat 22 is connected to the main machine 1, the locking element 31 moves to the unlocking position to the right, then the second attachment docking module 222 is aligned and docked to the second expansion function module downward, the locking element 31 in the unlocking position does not interfere with the insertion of the second expansion function module 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 locking position to the left, the locking element 31 abuts against the second expansion function module in the first direction (upward direction) to prevent the kettle seat 22 from moving upward, and locking is achieved. In this scheme, the recess 22122 is used to provide a moving space for the locking element 31, which is arranged ingeniously and does not need to be provided with an additional moving space, which is conducive to the miniaturization design of the kettle seat 22.

[0117] Further, as shown in FIG. 5, FIG. 6, FIG. 7 and FIG. 9, the locking element 31 comprises a locking portion 311 and a connecting block 312 connected thereto; the kettle seat 22 comprises a base 2212 provided with a third groove 22129, and the connecting block 312 is movably installed in the third groove 22129, and the third groove 22129 is communicated with the recess 22122 through a first through hole 22125. When the locking element 31 is in the locking position, the locking portion 311 passes through the first through hole 22125 to abut against the second expansion function module in the first direction. In this scheme, the locking element 31 is simple in structure, easy to assemble, and less modified to the structure of the kettle seat 22.

[0118] Further, as shown in FIG. 7 and FIG. 9, under the elastic force of the elastic element 32, the locking element 31 on the kettle seat 22 removed remains in the locking position. The locking portion 311 is provided with a guide slope 3111, which contacts and cooperates with the outer wall of the main machine when the kettle seat 22 is assembled with the second expansion function module of the main machine 1 to drive the locking element 31 to move to the unlocking position. The guide slope 3111 contacts the second expansion function module when the kettle seat 22 moves downward to the guide slope 3111 of the locking portion 311, and during the continuous downward movement of the kettle seat 22, the guide slope 3111 is subjected to the reaction force of the second expansion function module, so that the locking portion 311 moves to the unlocking position, without the need for manually operating the locking element 31, which is convenient for assembly. In addition, a groove (not shown in the figure) can be correspondingly provided on the second expansion function module, and when the kettle seat 22 continues to move downward until it is docked to the second expansion function module, the locking portion 311 moves from the above-mentioned unlocking position to the locking position, and the whole process does not need to manually operate the locking element 31, which is convenient for assembly.

[0119] Further, as shown in FIGS. 6, 7 and 9, the hole wall of the first through hole 22125 is in clearance fit with the circumferential outer contour of the locking portion 311, and is also used to guide the locking element 31 to move between the locking position and the unlocking position, so as to limit the movement of the locking element 31 in other directions to deviate from the locking position or the unlocking position. In a specific embodiment, the locking element 31 moves in the front-rear direction of the multifunctional water purifier 100 to switch between the locking position and the unlocking position, and the hole wall of the first through hole 22125 can limit the movement of the locking element 31 in the left-right direction and the up-down direction.

[0120] Further, as shown in FIGS. 5 to 7, the locking portion 311 is provided with a limiting long hole 3121, and the base 2212 is provided with a limiting column 22126. The limiting column 22126 is inserted into the limiting long hole 3121, and the limiting long hole 3121 can be displaced relative to the limiting column 22126 along the length direction of the limiting long hole 3121. The limiting column 22126 cooperates with the limiting long hole 3121 to guide the locking element 31 to move between the locking position and the unlocking position, so as to further limit the movement of the locking element 31 in other directions to deviate from the locking position or the unlocking position, and ensure that the locking element 31 can accurately switch between the locking position and the unlocking position.

[0121] Further, as shown in FIGS. 5 and 6, the kettle seat 22 further comprises a bolt 225, which is screwed into the threaded hole of the limiting column 22126; the nut of the bolt 225 abuts against the locking element 31 along the axial direction of the nut, so as to press the locking element 31 against the groove wall of the third groove 22129. Specifically, the locking element 31 further comprises a mounting column 314, which is connected in sequence with the connecting block 312 and the locking portion 311 in the direction towards the recessed portion 22122; one end of the elastic element 32 is connected to the base 2212, and the other end is sleeved on the mounting column 314; the locking portion 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, so as to complete the assembly of the locking element 31. The assembly requires fewer components, is convenient to assemble, and can control the cost. 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 gasket (not shown in the figure) is further arranged between the nut of the bolt 225 and the locking element 31.

[0122] In an embodiment, as shown in FIGS. 6 to 8, the locking element 31 further comprises a pushing portion 313 connected to the connecting block 312. The base 2212 is provided with a second through hole 22127, and the pushing portion 313 passes through the second through hole 22127 and extends to the outside of the kettle seat 22. When unlocking is needed, an external force pushes the pushing portion 313, so that the locking element 31 moves to the unlocking position. The pushing portion 313 is used for user operation, so as to facilitate the user to unlock the kettle seat 22.

[0123] Further, as shown in FIG. 6 and FIG. 8, the second through hole 22127 is arranged on the bottom wall of the base 2212, and the pushing part 313 partially extends below the lower surface of the base 2212. Specifically, the kettle seat 22 is usually not required to be removed, i.e., the kettle seat 22 is usually in a state of being always connected with the main machine 1, and the pushing part 313 is arranged at the bottom of the base 2212 to avoid unlocking due to accidental touching of the pushing part 313 in the normal use state of the kettle 2.

[0124] Further, as shown in FIG. 8, the lower surface of the base 2212 is provided with four supporting legs 22128, which are respectively 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 supporting leg 22128 to avoid deformation of the pushing part 313 due to long-time extrusion by the placement table, thereby affecting the locking function. Of course, the number of the supporting legs 22128 is not limited to four, but can be one (such as a whole square ring-shaped supporting leg), two (such as two long strip-shaped supporting legs 22128), three or more.

[0125] In an embodiment, as shown in FIG. 3 and FIG. 4, the kettle 2 further comprises an in-place detection assembly 24 for detecting whether the kettle body 21 is installed in place.

[0126] Further, the in-place detection assembly 24 comprises an in-place detection reed switch 241 and an in-place detection magnet 242, the in-place detection reed switch 241 is installed on the kettle seat 22, and the in-place detection magnet 242 is installed on the kettle body 21, and the in-place detection magnet 242 cooperates with the in-place detection reed switch 241 to detect whether the kettle body 21 is installed in place. Specifically, when the kettle body 21 is installed in place, the magnetic field of the in-place detection magnet 242 can make the reed of the in-place detection reed switch 241 close, and the circuit of the in-place detection reed switch 241 is turned on; when the kettle body 21 is not installed in place, the in-place detection magnet 242 is far away from the in-place detection reed switch 241, the reed of the in-place detection reed switch 241 is broken, and the circuit of the in-place detection reed switch 241 is turned off. Thus, by obtaining the on-off state of the circuit of the in-place detection reed switch 241, it is determined whether the kettle body 21 is installed in place.

[0127] In an embodiment, as shown in FIG. 2 and FIG. 3, the kettle seat 22 is further provided with a sterilization lamp assembly 226, and the kettle body 21 is provided 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, thereby ensuring healthy drinking.

[0128] Further, as shown in FIG. 3 and FIG. 4, the sterilization lamp assembly 226 comprises a sterilization lamp 2261 and a lampshade 2262, the sterilization lamp 2261 is installed in the lampshade 2262, the lampshade 2262 is installed on the kettle seat 22, the sterilization lamp 2261 is installed through the lampshade 2262, and the lampshade 2262 can also protect and dustproof the sterilization lamp 2261.

[0129] Further, as shown in FIG. 3, one end of the lampshade 2262 towards the light-transmitting structure 214 is hemispherical, which is beneficial to the light emitted by the sterilization lamp 2261 to enter the kettle body 21 more uniformly.

[0130] Further, as shown in FIG. 3, 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 distribution of sterilization light entering the kettle body 21 and improves the sterilization efficiency.

[0131] In an embodiment, as shown in FIG. 3, the light-transmitting structure 214 at least partially extends into the kettle cavity 215, and one end of the light-transmitting structure 214 extending into the kettle cavity 215 is hemispherical, so as to improve the uniformity of the distribution of sterilization light entering the kettle body 21.

[0132] In an embodiment, as shown in FIG. 1, FIG. 4 and FIG. 9, the outer cover 2211 covers the outer periphery of the bracket 2213. The outer cover 2211 is provided with a third through hole 22113 and a fourth through hole 22114, the third through hole 22113 is used to allow the kettle body 21 and the kettle seat 22 to realize fluid communication through the drain valve assembly 23, and the fourth through hole 22114 is used for the sterilization lamp assembly 226 installed on the bracket 2213 to emit sterilization light towards the kettle body 21. The outer cover 2211 covers the outline of the bracket 2213 and the parts installed on the bracket 2213, so as to ensure the aesthetic appearance of the kettle seat 22.

[0133] In an embodiment, as shown in FIG. 9 and FIG. 13, the main machine 1 further comprises a water purification tank 13 and a main machine water inlet 14, and the kettle seat 22 comprises a first low water level detection mechanism 251 and a water storage cavity 252. As shown in FIG. 3, when the kettle body 21 is installed on the kettle seat 22, the kettle body 21 and the water storage cavity 252 communicate with each other. In a specific embodiment, the kettle body 21 and the kettle seat 22 realize fluid communication through the drain valve assembly 23, and when the kettle body 21 is installed on the kettle seat 22, the drain valve assembly 23 is in an open state, and the kettle body 21 and the water storage cavity 252 communicate with each other.

[0134] As shown in FIG. 10 and FIG. 13, the lowest point of the water storage cavity 252 is below the lowest point of the kettle cavity 215 of the kettle body 21, and the first low water level detection mechanism 251 is configured to obtain low water level information in the water storage cavity 252 to determine whether the water level in the kettle body 21 reaches the preset low water level. When the kettle body 21 is installed on the kettle seat 22, the multifunctional water purifier 100 has the first working mode, at this time, the kettle cavity 215 is in communication with the water purifying tank 13, and when the multifunctional water purifier 100 is turned on to supply water, the water purifying tank 13 and the kettle body 21 supply water to the main machine water inlet 14 respectively and simultaneously, and the water in the kettle body 21 flows to the main machine water inlet 14 through the water storage cavity 252. Of course, the multifunctional water purifier 100 can also have a second working mode, at this time, the kettle cavity 215 is not in communication with the water purifying tank 13.

[0135] In the above technical solution, when the multifunctional water purifier 100 is turned on to supply water, the water in the kettle body 21 flows to the main machine water inlet 14 of the main machine 1 through the water storage cavity 252, and the lowest point of the water storage cavity 252 is below the lowest point of the kettle cavity 215 of the kettle body 21, which is beneficial 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 seat 22 and the multifunctional water purifier 100 is in the first working mode, the kettle body 21 and the water purifying tank 13 are both in communication, and when the water in the kettle body 21 and the water purifying tank 13 is in a static state and does not reach the corresponding low water level, the water levels of the kettle body 21 and the water purifying tank 13 are equal, so that the water level detection mechanism arranged in the main machine 1 of the multifunctional water purifier 100 can detect the water levels of the kettle body 21 and the water purifying tank 13 simultaneously. However, during the process of supplying water by the kettle body 21 and the water purifying tank 13 respectively and simultaneously, if the water level of the kettle body 21 drops slower than the water purifying tank 13 due to some reasons (for example, the cross-sectional area of the kettle body 21 is larger than the cross-sectional area of the water purifying tank 13 at the same horizontal plane), the multifunctional water purifier 100 of the present solution is provided with the first low water level detection mechanism 251 to detect the low water level information in the water storage cavity 252, so as to ensure that the water in the kettle body 21 can reach the preset low water level of the kettle body 21, reduce stale water, and ensure healthy drinking water.

[0136] In an embodiment, as shown in FIG. 3, the water storage cavity 252 is below the kettle cavity 215, which is beneficial to drain the water in the kettle cavity 215.

[0137] In an embodiment, as shown in FIG. 3, the bottom of the kettle cavity 215 is in communication with the water storage cavity 252, and the water in the kettle cavity 215 can be completely supplied to the outside through the water storage cavity 252, that is, the water in the kettle cavity 215 can be completely drained without leaving stale water.

[0138] Further, as shown in FIG. 3, the bottom of the kettle cavity 215 is in communication with the top of the water storage cavity 252. Specifically, as shown in FIG. 10, the multifunctional water purifier 100 is provided with a first pump body 161, under the water power provided by the first pump body 161, the water purifying tank 13 and the kettle body 21 supply water to the main machine water supply port 14 respectively and simultaneously. In this scheme, the bottom of the kettle cavity 215 is in communication with the top of the water storage cavity 252, which is conducive to the water in the kettle cavity 215 quickly entering the water storage cavity 252, thereby improving the water supply speed.

[0139] In an embodiment, as shown in FIG. 3, when the multifunctional water purifier 100 is in the first working mode, the kettle cavity 215 is in communication with the water purifying tank 13 through the water storage cavity 252, without the need to set an additional connecting pipeline on the water purifying tank 13 to communicate with the water purifying tank 13, the structure is simplified, and the arrangement is more reasonable.

[0140] Further, as shown in FIG. 9 and FIG. 10, when the kettle body 21 is installed on the kettle seat 22, the bottom of the water storage cavity 252 is connected with the waterway of the main machine 1, which is conducive to draining as much water as possible from the water storage cavity 252 and reducing the residual stale water in the water storage cavity 252.

[0141] Further, as shown in FIG. 9, the kettle seat 22 includes a water storage box 25, and the water storage cavity 252 is formed inside the water storage box 25. The first low water level detection mechanism 251 includes a first float 2511 and a first liquid level sensor 2512 which cooperate with each other, 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.

[0142] Further, as shown in FIG. 9, the volume of the water storage cavity 252 is ≥ three times the volume of the first float 2511, so that the water in the water storage cavity 252 above the low water level can provide sufficient buoyancy for the first float 2511, avoiding the suction force of the first pump body 161 directly sucking the first float 2511 to the bottom of the water storage box 25, causing the first low water level detection mechanism 251 to misjudge the water shortage of the kettle body 21.

[0143] In an embodiment, as shown in FIG. 4 and FIG. 9, the water storage box 25 is arranged in the accommodating space 2214 formed between the bracket 2213 and the base 2212, and the water storage box 25 is located above the adapter 223 and the second attachment docking module 222, so that the components are arranged compactly and the space utilization rate is high.

[0144] In an embodiment, as shown in FIG. 9, 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 cavity 252 is within the preset water level range, the first float 2511 is within the 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 cavity 252 drops to the 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 kettle body 21 reaches 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, so that when the first float 2511 is within the 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.

[0145] Further, as shown in FIG. 9, the water storage box 25 is provided with a hollow column 2531, and the first float 2511 is movably installed in the hollow column 2531.

[0146] Further, as shown in FIG. 9, the inner wall of the hollow column 2531 is provided with a plurality of abutting ribs 25311; all the abutting ribs 25311 are distributed along the circumference of the first float 2511, and the abutting ribs 25311 are used to guide the moving direction of the first float 2511. In this scheme, the abutting 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 friction generated when the abutting ribs 25311 collide with the first float 2511 is low, so as not to affect the water level detection result.

[0147] Further, as shown in FIG. 9, the cross section of the hollow column 2531 is in the shape of an open ring, and the hollow column 2531 is provided with an opening to ensure that the first float 2511 can be in contact with the water in the water storage cavity 252.

[0148] Further, as shown in FIG. 3 and FIG. 9, the water storage box 25 includes a box body 253 and a cover body 254, which are sealingly connected and form the water storage cavity 252. The hollow column 2531 is arranged in the box body 253, and one end of the hollow column 2531 in the axial direction is open and faces the cover body 254. When assembling the first float 2511, the first float 2511 is inserted into the hollow column 2531 downward, and then the cover body 254 is connected with the box body 253, which is fast and convenient.

[0149] In an embodiment, as shown in FIG. 9, the bottom of the water storage box 25 is provided with a box body communication port 255. When the kettle seat 22 is connected to the main machine 1, the box body communication port 255 is connected with the waterway of the main machine 1 through the second attachment waterway docking element 2221.

[0150] Further, as shown in FIG. 3 and FIG. 9, the water storage box 25 is provided with a guide structure 2532, which is arranged above the box body communication port 255 and is provided with a guide channel 25321. The second attached waterway docking element 2221 comprises an attached waterway valve core 22211, one end of which is movably inserted into the guide channel 25321, and the guide channel 25321 is used to guide the attached waterway valve core 22211 to move between the open position and the closed position. When the attached waterway valve core 22211 is in the open position, the box body communication port 255 is in communication with the waterway of the main machine 1; when the attached waterway valve core 22211 is in the closed position, the box body communication port 255 is fluidly blocked. In this scheme, the guide structure 2532 corresponds to the valve body structure, which is used in cooperation with the attached waterway valve core 22211 to simplify the structure of the second attached waterway docking element 2221.

[0151] In an embodiment, the capacity of the kettle body 21 is greater than that of the purified water tank 13, providing a large amount of water storage for the user. The lowest point of the kettle cavity 215 is not higher than that of the purified water storage cavity 131 of the purified water tank 13. Generally, there are many components in the main machine 1, and the height dimension of the purified water tank 13 is limited. In order to stabilize the center of gravity of the main machine 1, the purified water tank 13 is usually located at the upper part of the main machine 1, and the height dimension of the kettle body 21 is only affected by the kettle seat 22, so as to increase the capacity of the kettle body 21 by extending the height of the kettle body 21 as much as possible. In this way, the lowest point of the kettle cavity 215 is lower than or flush with that of the purified water storage cavity 131. When the kettle 2 is connected to the main machine 1 and the multifunctional 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 cavity 252 to determine that the kettle body 21 and the purified water tank 13 respectively reach the corresponding preset low water level. At this time, the first low water level detection mechanism 251 serves as the low water level detection mechanism of the whole machine, and the low water level information of the kettle body 21 is used as the low water level judgment standard of the whole machine, which is beneficial to the water in the kettle cavity 215 being discharged as much as possible and avoiding misjudgment of water shortage in the kettle cavity 215 due to using the low water level information of the purified water tank 13 as the low water level judgment standard of the whole machine.

[0152] Further, as shown in FIG. 3 and FIG. 10, the lowest point of the kettle cavity 215 is below that of the purified water storage cavity 131, so as to increase the capacity of the kettle cavity 215.

[0153] In an embodiment, the main machine 1 further comprises a second low water level detection mechanism. When the kettle 2 is not connected to the main machine 1, the second low water level detection mechanism is used to obtain the low water level information in the purified water storage cavity 131 to timely supplement water when the purified water tank 13 is short of water.

[0154] Further, as shown in FIG. 13 and FIG. 17, the host 1 further comprises a low water level detection box 151, the low water level detection box 151 comprises a containing cavity 1512 in communication with the purified water storage cavity 131, the lowest point of the containing cavity 1512 is below the lowest point of the purified water storage cavity 131, and a second low water level detection mechanism is arranged on the low water level detection box 151. When the multifunctional water purifier 100 is in the water supply state, the water in the purified water storage cavity 131 flows to the host water supply port 14 through the containing cavity 1512, which is conducive to draining the water in the purified water storage cavity 131 as much as possible. In a specific embodiment, when the kettle 2 is connected to the host 1 and the multifunctional water purifier 100 is in the first working mode, the lowest point of the kettle cavity 215 is below the lowest point of the purified water storage cavity 131, and if the water in the purified water tank 13 is taken to a water level that is lowered into the containing cavity 1512, at this time there is still water in the kettle cavity 215. Since the cross-sectional area of the kettle cavity 215 is greater than the cross-sectional area of the containing cavity 1512, the water level in the kettle cavity 215 drops at a lower speed than the water level in the containing cavity 1512. In order to avoid misjudging that the kettle cavity 215 is out of water, at this time, the first low water level detection mechanism 251 is used as the low water level detection mechanism of the whole machine.

[0155] Further, as shown in FIG. 13, the containing cavity 1512 is below the purified water storage cavity 131, which is conducive to draining the water in the purified water storage cavity 131.

[0156] Further, as shown in FIG. 3 and FIG. 10, the water storage cavity 252 is below the kettle cavity 215, and the lowest point of the water storage cavity 252 is below the lowest point of the purified water storage cavity 131. In this way, when the kettle 2 is connected to the host 1 and the multifunctional water purifier 100 is in the first working mode, the first low water level detection mechanism 251 can be used to judge that the kettle body 21 and the purified water tank 13 respectively reach the corresponding preset low water level by obtaining the low water level information in the water storage cavity 252.

[0157] In an embodiment, as shown in FIG. 13, the bottom of the purified water storage cavity 131 is in communication with the top of the containing cavity 1512, so that the water in the purified water storage cavity 131 can be drained.

[0158] In an embodiment, as shown in FIG. 13, the low water level detection box 151 is in an elongated shape, and the length of the low water level detection box 151 extends in the height direction of the host 1, thereby reducing the occupation of the transverse space in the host 1.

[0159] Further, as shown in FIG. 9 and FIG. 13, the cross-sectional area of the accommodating cavity 1512 is smaller than the cross-sectional area of the water storage cavity 252, which makes full use of the transverse space in the kettle seat 22 to increase the volume as much as possible, so that the water above the low water level can provide sufficient buoyancy for the first float 2511 to avoid the suction force of the first pump body 161 directly sucking the first float 2511 to the bottom of the water storage box 25. Preferably, the cross-sectional area of the accommodating cavity 1512 is one-third to one-half of the cross-sectional area of the water storage cavity 252.

[0160] In an embodiment, as shown in FIG. 13, the second low water level detection mechanism includes a second float 1511 and a second liquid level sensor (not shown in the figure) that cooperate with each other; the second float 1511 is located in the accommodating cavity 1512, and the second liquid level sensor is connected to the outside of the low water level detection box 151.

[0161] Further, as shown in FIG. 13 and FIG. 14, the main machine 1 further includes a first pump body 161, under the water power provided by the first pump body 161, the water tank 13 and the kettle body 21 supply water to the main machine water inlet 14 respectively and simultaneously. The second float 1511 can move between a first position and a second position, the second position is below the first position, and the position height of the second position in the accommodating cavity 1512 is h1. Since the first pump body 161 has a certain suction force, in order to avoid the first pump body 161 directly sucking the second float 1511 to the bottom of the low water level detection box 151, the position height h1 is configured to enable the buoyancy received by the second float 1511 to be greater than the suction force of the first pump body 161 received by the second float 1511, so as to prevent the second float 1511 from moving downward beyond the second position. Preferably, the position height h1 is one-third to one-half of the height of the accommodating cavity 1512.

[0162] Further, as shown in FIG. 13, the low water level detection box 151 is provided with a float limiting column 1515, the float limiting column 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 column 1515 and 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 above-mentioned first position, and the position of the second limiting piece 1517 is the above-mentioned second position.

Specifically, as the space of the container cavity 1512 is limited, if foreign matters enter the container cavity 1512 through the tank communication port 132, it is inconvenient to clean, and even the low water level detection box needs to be replaced, increasing the use burden.

[0164] Further, as shown in FIG. 15, the intercepting structure 133 includes a ring portion 1331 and a plurality of intercepting ribs 1332, the number of the intercepting ribs 1332 can be two, three, four or even more, and all the intercepting ribs 1332 are distributed along the circumference of the ring portion 1331. The ring portion 1331 is located opposite to the tank communication port 132 in the axial direction of the ring portion 1331, one end of the intercepting rib 1332 is connected to the ring portion 1331, and the other end of the intercepting rib 1332 is connected to the tank of the water purifying tank 13. The intercepting effect can be adjusted by adjusting the spacing between two adjacent intercepting ribs 1332. Preferably, the tank communication port 132 is a circular through hole with a diameter ≥ 5 mm to ensure smooth water inflow and outflow of the water purifying tank 13.

When the kettle 2 is not connected to the main machine 1, the high water level detection mechanism is used to obtain the high water level information in the water storage cavity 131. When the kettle 2 is connected to the main machine 1, the high water level detection mechanism obtains the high water level information in the water storage cavity 131 to determine whether the kettle body 21 and the water purifying tank 13 reach the corresponding preset high water level, respectively. Specifically, when the water in both the kettle body 21 and the water purifying tank 13 is in a static state and neither reaches the corresponding low water level, the water levels of the kettle body 21 and the water purifying tank 13 are equal, and the high water level detection mechanism is used as the high water level detection mechanism of the whole machine. Therefore, it is not necessary to additionally configure a corresponding high water level detection mechanism on the kettle 2, which can simplify the structure of the kettle 2 and reduce the processing cost.

[0166] Further, as shown in FIG. 13, the main machine 1 further includes a high water level detection box 152 located in the water storage cavity 131. The high water level detection box 152 includes a cavity 1522, and the side wall of the high water level detection box 152 is provided with a fifth through hole 1523.

[0167] In an embodiment, when the kettle 2 is connected to the main machine 1 and the multifunctional water purifier 100 is in the first working mode, at this time, when the multifunctional water purifier 100 starts to make water, the water purifying tank 13 and the kettle 2 are respectively and simultaneously replenished with water. In the existing part of the multifunctional water purifier, when starting to make water, the water purifying tank is first replenished with water, and then the kettle is replenished with water from the water purifying tank. The water replenishment time is long, and the water level detection is not accurate, or water level detectors need to be respectively arranged for the kettle and the water purifying tank. In the present scheme, the water purifying tank 13 and the kettle 2 are separated and simultaneously replenished with water, and the water replenishment time is short.

[0168] Further, as shown in FIG. 9, when the kettle 2 is connected to the main machine 1 and the multifunctional water purifier 100 starts to make water, the purified water provided by the main machine 1 flows into the kettle cavity 215 through the water storage cavity 252. In this way, by arranging the kettle connecting port 216 on the kettle 21, the water inlet and outlet of the kettle 21 can be realized, and it is not necessary to additionally open a water inlet on the kettle 21, which can simplify the structure of the kettle 21 and the connection relationship between the kettle 2 and the main machine 1.

In this way, by arranging the tank connecting port 132 on the water purifying tank 13, the water inlet and outlet of the water purifying tank 13 can be realized, and it is not necessary to additionally open a water inlet on the water purifying tank 13, which can simplify the structure of the water purifying tank 13 and the pipeline arrangement in the main machine 1.

[0170] It should be understood that in the process of replenishing water in the water purifying tank 13 and the kettle 2, one way of water flow enters the water purifying tank 13 from the low water level detection box 151, and the other way of water flow enters the kettle 21 from the water storage box 25.

In this way, the water collecting member 18 can realize the water connection with the water purifying tank 13, the functional water machine 4, the filter core assembly 171 and the host water outlet 14 through the four connecting ports, and the water collecting member 18 has a simple structure and only needs four water connection relationships, thereby reducing the number of pipelines and the number of pipeline joints.

[0175] Further, as shown in FIG. 17, the host 1 is provided with a second pump body 162. Under the power provided by the second pump body 162, the raw water enters the filter core assembly 171 and is discharged after being purified by the filter core assembly 171. In order to ensure that the water has enough power to flow through the filter core assembly 171, the second pump body 162 is selected as a booster pump.

[0176] In an embodiment, as shown in FIG. 10 and FIG. 18, the water collection piece 18 is further provided with a fifth connecting port 189. When the kettle 2 is connected with the main machine 1, the fifth connecting port 189 is communicated with the kettle 2 through the fourth pipeline 195, and the purified water flows into or out of the kettle 2 through the water collection piece 18.

[0188] In an embodiment, as shown in FIG. 10 and FIG. 17, the first pump body 161 in the main machine 1 is vertically arranged below the purified water tank 13, and the third pipeline 193 is connected with the inlet end of the first pump body 161. The setting position of the first pump body 161 is optimized so that the fourth connecting port 184 of the water collecting piece 18 and the inlet end of the first pump body 161 have a short distance in the up-down direction of the multifunctional water purifier 100, which is beneficial to shorten the length of the third pipeline 193.

[0193] In an embodiment, as shown in FIG. 10 and FIG. 17, the multifunctional water purifier 100 further comprises a heating element 172, and the purified water pumped by the first pump body 161 is supplied to the main machine water supply port 14 via the heating element 172. Specifically, when the user takes normal temperature water, the heating element 172 does not work, and the purified water flows to the main machine water supply port 14 via the heating element 172; when the user takes hot water, the heating element 172 works, and the purified water flows into the heating element 172, is heated to form hot water via the heating element 172, and then flows to the main machine water supply port 14.

[0194] Further, as shown in FIG. 10 and FIG. 17, the heating element 172 is located between the horizontal box body 1514 and the filter core assembly 171, and the bottom of the first pump body 161 is connected with a water outlet pipeline 194.

The drainage component 173 can be manually opened and drain water outward. When the multifunctional water purifier 100 needs to be repaired due to failure, the water in the pipeline of the multifunctional water purifier 100 needs to be drained first. If the water outlet failure occurs at the water supply port 14 of the main machine, the drainage component 173 can be used for manual drainage to ensure that the repair work can be carried out smoothly.

[0196] In an embodiment, as shown in FIG. 10 and FIG. 18, the second side wall 1852 of the water collecting piece 18 away from the water supply port 14 of the main machine is provided with a second connecting port 182, which is communicated with the functional water tank 41 through a second pipeline 192.

[0197] Further, as shown in FIG. 10, the second pipeline 192 extends in the horizontal plane. Specifically, the main machine 1 is docked with the first attachment docking module 43 of the functional water machine 4 through the first expansion function module 11. The input end of the first main machine waterway docking element 111 of the first expansion function module 11, the outlet end of the second pipeline 192 and the second connecting port 182 are arranged at the same horizontal height. In this way, the second pipeline 192 can be arranged to extend along the horizontal plane, thereby reducing the occupation of the second pipeline 192 in the vertical space.

[0198] Further, as shown in FIG. 10 and FIG. 18, the fifth connecting port 189 is arranged on the second side wall 1852, and the second connecting port 182 and the fifth connecting port 189 are sequentially distributed in the direction towards the kettle 2. The five connecting ports on the water collecting piece 18 are arranged compactly, the limited space on the peripheral side wall of the water collecting piece 18 is maximized, and the arrangement of the first pipeline 191, the second pipeline 192, the third pipeline 193 and the fourth pipeline 195 is regular.

[0199] In an embodiment, as shown in FIG. 18 and FIG. 19, the water collecting piece 18 is provided with a water storage cavity 186, which is communicated with the water purifying tank 13, the kettle 2 and the functional water tank 41. By arranging the water storage cavity 186 on the water collecting piece 18, the fluid can be buffered. When the multifunctional water purifier 100 is turned on to produce water, the water collecting piece 18 is in a state of one inlet and two outlets, that is, the third connecting port 183 is communicated with the purified water provided by the filter core assembly 171, the first connecting port 181 supplies water to the water purifying tank 13, and the fifth connecting port 189 supplies water to the kettle 2. In this state, the fluid buffered in the water storage cavity 186 can be beneficial to improve the stability of water outlet of the first connecting port 181 and the fifth connecting port 189.

[0200] Further, as shown in FIG. 18 and FIG. 19, the water collecting piece 18 is provided with a temperature detecting element 187 to obtain the water temperature information in the water storage cavity 186. Specifically, since the multifunctional water purifier 100 is provided with the water purifying tank 13 and the kettle 2, the water purifying tank 13 is located in the main machine shell 12, and the kettle 2 is exposed, which causes the environment temperature of the water purifying tank 13 and the kettle 2 to be possibly different, and further causes the water temperature of the water purifying tank 13 and the kettle 2 to be different, and when the multifunctional water purifier 100 is in the first working mode, the user takes water, which is supplied by the water purifying tank 13 and the kettle 2 at the same time, and thus the water temperature of the mixed water of the water purifying tank 13 and the kettle 2 needs to be detected, if only the NTC element is configured in the water purifying tank 13, the water temperature detection is not accurate, which causes the water temperature to be too high to cause the high steam, or the water temperature to be too low to meet the user's taking demand, in the present mode, the water purifying tank 13 and the kettle 2 are mixed in the water storage cavity 186, and the temperature detecting element 187 is configured to preliminarily detect the temperature of the mixed water in the water storage cavity 186, and then the water is supplied to the heating element 172, which can improve the accuracy of the temperature detection, and avoid the problems of the high steam of the heating element 172 or the water temperature being too low.

[0201] In an embodiment, as shown in FIG. 18 and FIG. 19, the bottom wall of the water storage cavity 186 is provided with a flow guide groove 1861, and the first connecting port 181, the second connecting port 182 and the fourth connecting port 184 are in communication with the flow guide groove 1861. Specifically, when the multifunctional water purifier 100 in the first working mode is started to make water, since the flow guide groove 1861 is low, the water flow entering the third connecting port 183 can quickly enter the flow guide groove 1861, and then quickly supply the water purifying tank 13 through the first connecting port 181, and the rest of the water supplies the kettle 2 through the fifth connecting port 189; when the multifunctional water purifier 100 in the first working mode is started to supply water, the water in the water purifying tank 13 enters the flow guide groove 1861 through the first connecting port 181, and the water in the kettle 2 enters the flow guide groove 1861 after entering the water storage cavity 186 through the fifth connecting port 189, and the water in the flow guide groove 1861 can quickly enter the fourth connecting port 184 in communication therewith, and supply water to the first pump body 161 through the fourth connecting port 184.

[0202] Further, as shown in FIG. 18 and FIG. 19, the flow guide groove 1861 includes a first groove body 18611 and a second groove body 18612 which are in communication with each other, and the first groove body 18611 is located at the side of the water storage cavity 186 close to the functional water machine 4. The first connecting port 181, the second connecting port 182 and the fourth connecting port 184 are respectively in communication with the first groove body 18611, and the outlet end of the third connecting port 183 of the water collecting piece 18 is located above the second groove body 18612, and the third connecting port 183 is used to introduce the purified water supplied by the filter core assembly 171. Specifically, when the multifunctional water purifier 100 in the first working mode is turned on to produce water, the water flow introduced by the third connecting port 183 first enters the second groove body 18612 and then flows into the first groove body 18611, which can reduce the turbulence degree of the water flow to a certain extent and reduce the noise.

[0203] Further, as shown in FIG. 18, the first groove body 18611 includes a first groove wall 186111 which is connected with the second groove body 18612, and the first groove wall 186111 extends in a downward direction and away from the second groove body 18612. The inclined arrangement of the first groove wall 186111 can guide the water flow in the second groove body 18612 to the first groove body 18611.

[0204] In an embodiment, as shown in FIG. 18 and FIG. 19, the water collecting piece 18 includes a water collecting box 1881 and a water collecting cover 1882 which are detachably connected and sealed to form the water storage cavity 186.

[0205] In an embodiment, the volume of the water storage cavity 186 is greater than or equal to 18cm 3 , which maximizes the use of the empty internal space at the bottom of the purified water outlet of the filter core assembly 171, and increases the volume of the water storage cavity 186 as much as possible to avoid empty pumping of the first pump body 161.

[0206] In an embodiment, as shown in FIG. 3 and FIG. 10, when the kettle 2 is in a connected state with the main machine 1, the water collecting piece 18 is located below the lower limit position of the first float 2511. Specifically, when the multifunctional water purifier 100 in the first working mode is turned on to supply water, the water in the kettle 2 first enters the water collecting piece 18 and then flows to the first pump body 161. If the position of the water collecting piece 18 is higher than the lower limit position of the first float 2511, when the water in the water collecting piece 18 is pumped empty, the first float 2511 in the water storage box 25 has not reached its lower limit position, which causes the first pump body 161 to continue pumping water. If the water taken at this time is hot water, the empty pumping will also cause steam spraying, which poses a hidden danger. Therefore, the position of the water collecting piece 18 is arranged below the lower limit position of the first float 2511 to avoid empty pumping.

[0207] In an embodiment, as shown in FIG. 16, the kettle body 21 is further provided with a spout 218 and a handle 219, the spout 218 is used to pour water, and the handle 219 is used for the user to hold.
