[0001] This application claims priority to the patent applications filed with the State Intellectual Property Office of the People's Republic of China, with the application numbers CN202510335653.3, CN202421892918.7 and CN202520947788.0, the disclosures of which are hereby incorporated by reference in their entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of water purification equipment, in particular to a multifunctional water purifier. BACKGROUND

[0003] Water purification equipment can provide users with directly drinkable purified water and is widely used in homes, offices and other places. As users have more and more diversified functional requirements for water purification equipment, single-configuration water purification equipment is difficult to meet the needs of more types of users.

[0004] Some existing water purification equipment adds a detachable kettle to enrich the functions of the water purification equipment. Specifically, the base of the main machine of the water purification equipment is integrally formed with a mounting seat, the detachable kettle is detachably mounted on the mounting seat, the main machine is provided with a communicating device, the detachable kettle is connected with the waterway of the communicating device, and the main machine judges the water level information in the detachable kettle by acquiring the water level of the communicating device. When the water purification equipment is also provided with a purified water tank and the purified water tank is in communication with the communicating device, if the water level in the detachable kettle drops slower than the water level in the purified water tank due to some reasons (for example, the cross-sectional area of the kettle cavity of the detachable kettle is larger than the cross-sectional area of the chamber of the purified water tank at the same horizontal plane, or for example, the bottom wall of the kettle cavity of the detachable kettle is located below the chamber of the purified water tank), the main machine will stop water supply because it first judges that the water level in the purified water tank has reached the low water level, while the water level in the detachable kettle has not reached the corresponding low water level at this time, resulting in accumulation of stale water in the communicating device, which is not conducive to healthy drinking. SUMMARY

[0005] Based on the above-mentioned defects in the prior art, the purpose of the present application is to provide a multifunctional water purifier, which is beneficial to drain as much water as possible from the kettle cavity and avoid user's mistaken belief that the machine is malfunctioning and reduce stale water.

[0006] The present application has the following technical effects:

[0007] The application provides a multifunctional water purifier, which comprises a water purifying tank, a kettle seat, a kettle body, a first low water level detection mechanism, a processor and a second low water level detection mechanism. The kettle body is configured to increase the water storage capacity of the multifunctional water purifier, and the kettle body can be removed for directly taking water, so that the user can quickly take the required amount of water according to the water taking demand, and the function is more abundant. When it is determined that the kettle body is installed on the kettle seat, the low water level information obtained by the first low water level detection mechanism is used as the low water level information of the multifunctional water purifier, which is beneficial to drain the water in the kettle cavity as much as possible, and avoids that the multifunctional water purifier reminds the user of water shortage when there is still residual water in the kettle body, causing the user to mistakenly think that the machine is malfunctioning.

[0008] In addition, when the kettle body is installed on the kettle seat, the kettle body and the water purifying tank are in communication, and when the water in the kettle body and the water purifying tank is in a static state and does not reach the corresponding low water level, the water levels of the kettle body and the water purifying tank are equal. Therefore, the water level detection mechanism of the multifunctional water purifier can detect the water levels of the kettle body and the water purifying tank at the same time. However, during the process of supplying water to the kettle body and the water purifying tank respectively and simultaneously, if the water level of the kettle body decreases slower than that of the water purifying tank due to some reasons (for example, the cross-sectional area of the kettle body is larger than that of the water purifying tank at the same horizontal plane), the multifunctional water purifier is provided with the first low water level detection mechanism to ensure that the water in the kettle body can reach the preset low water level of the kettle body, reduce stale water and ensure healthy drinking water.

[0055] The "front", "back", "left", "right", "up" and "down" mentioned in the present application are based on the marks in FIG. 1 and FIG. 10.

[0056] The multifunctional water purifier of the present application will be described in detail below according to FIG. 1 to FIG. 19.

[0057] In the present embodiment, as shown in FIG. 1, FIG. 10 and FIG. 16, the multifunctional water purifier 100 comprises a main machine 1 and a detachable kettle 2, the main machine 1 can be provided with a filter element assembly 171 for purifying raw water to form purified water, and the main machine 1 can also not be provided with the filter element assembly 171, and the main machine 1 can store purified water or mineral water provided by the user and considered clean by the user. As shown in FIG. 1, the detachable kettle 2 comprises a kettle body 21 and a kettle seat 22 which are detachably connected, and the kettle seat 22 is detachably connected to the main machine 1. As shown in FIG. 10 and FIG. 16, when the kettle seat 22 and the main machine 1 are in a connected state, the kettle seat 22 and the main machine 1 are connected in waterway to enable the main machine 1 to supply water to the kettle body 21 through the kettle seat 22.

[0058] In the above technical solution, the detachable kettle 2 is configured to increase the water storage capacity of the multifunctional water purifier 100. The kettle body 21 of the detachable kettle 2 is detachably connected with the kettle seat 22. When the kettle seat 22 is connected with the main machine 1, the main machine 1 supplies water to the kettle body 21 through the kettle seat 22. The kettle body 21 is not directly connected with the main machine 1, which facilitates quick removal or installation of the kettle body 21, convenient taking, easy operation, labor saving, and the user can directly take water by removing the kettle body 21. In this way, the user can freely and quickly take the required amount of water according to the water taking demand, and the function is rich. In addition, the kettle seat 22 is detachably connected with the main machine 1. If the pipeline or components in the kettle seat 22 fail, 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 demands. For example, when the user does not want to use the detachable kettle body 21 or the overall space is insufficient, the kettle seat 22 and the kettle body 21 can be removed together for storage, avoiding that the removal of only the kettle body 21 causes dust accumulation in the kettle seat 22. The dirt enters the whole machine water purifying waterway from the joint between the kettle seat 22 and the kettle body 21, causing the water purifying waterway to be polluted. In addition, the detachable kettle seat 22 can also avoid occupying space. It should be understood that during the normal use of the detachable kettle 2, the kettle seat 22 remains connected with the main machine 1, and only the kettle body 21 is taken, thereby reducing the burden on the user.

[0059] In an embodiment, the multifunctional water purifier 100 comprises a first low water level detection mechanism 251, a water purifying tank 13, a second low water level detection mechanism, and a processor. The first low water level detection mechanism 251 is configured to obtain low water level information of the kettle body 21, so that the processor determines whether the water level in the kettle body 21 reaches a preset low water level. The water purifying tank 13 is configured to store purified water, and the capacity of the kettle body 21 is greater than that of the water purifying tank 13. The second low water level detection mechanism is configured to obtain low water level information of the water purifying tank 13, so that the processor determines whether the water level in the water purifying tank 13 reaches a corresponding low water level. The processor is configured to use the low water level information obtained by the first low water level detection mechanism 251 as the low water level information of the multifunctional water purifier 100 when it is determined that the kettle body 21 is installed on the kettle seat 22. The low water level information of the kettle body 21 is obtained for the processor to determine whether the water level in the kettle body 21 reaches a preset low water level. In this technical solution, the kettle body is configured to increase the water storage capacity of the multifunctional water purifier. The user can also remove the kettle body to directly take water, and can freely and quickly take the required amount of water according to the water taking demand, and the function is more rich. When it is determined that the kettle body is installed on the kettle seat, the low water level information obtained by the first low water level detection mechanism is used as the low water level information of the multifunctional water purifier, which is beneficial to drain as much water as possible from the kettle cavity, and avoids that the multifunctional water purifier reminds the user of water shortage when there is still residual water in the kettle body, causing the user to mistakenly think that the machine is malfunctioning.

[0060] Further, the processor is further configured to acquire the low water level information obtained by the second low water level detection mechanism as the low water level information of the multifunctional water purifier 100 when it is determined that the kettle body is not installed on the kettle seat 22.

[0061] Further, the first low water level detection mechanism 251 is configured to acquire the low water level information in the water storage cavity 252 to obtain the low water level information of the kettle body 21.

[0062] In an embodiment, as shown in FIG. 10, when the kettle seat 22 and the main machine 1 are in a connected state, the circuit of the kettle seat 22 and the main machine 1 are connected, wherein the circuit connection between the kettle seat 22 and the main machine 1 can be used for signal transmission, can also be that the main machine 1 supplies power to the kettle seat 22, and of course can be both for signal transmission and power supply.

[0063] In an embodiment, the connection mode of the kettle body 21 and the kettle seat 22 includes clamping or buckling or adsorption connection, which has simple assembly structure and convenient operation.

[0064] Further, as shown in FIGS. 1 and 12, 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, so that the kettle body 21 can stably keep the clamped state with the kettle seat 22 under the gravity of the kettle body 21 itself. 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 along the left-right direction or the front-rear direction.

[0065] Further, as shown in FIG. 2, the circumferential side wall of the kettle body 21 extends downward to form an extension wall 211; 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. 1, the kettle seat 22 is provided with a clamping protrusion 22111, the clamping groove 213 is clamped with the clamping protrusion 22111, and the assembly of the kettle body 21 and the kettle seat 22 is realized. Specifically, since the kettle body 21 and the kettle seat 22 need to be connected in waterway, 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 waterway connection of the kettle seat 22, resulting in uneven surface of the kettle body bottom wall 212. In the present scheme, the extension wall 211 is provided, which can be clamped with the clamping protrusion 22111 on one hand, and can also cover the structure provided at the bottom of the kettle body 21 for waterway connection of the kettle seat 22 on the other hand, thereby improving the appearance of the kettle body 21 after being removed. Moreover, the bottom wall of the extension wall 211 is also used to form a support structure, so that the user can directly place the kettle body 21 on the desktop or other table top after removing it.

[0066] Further, as shown in FIG. 1, FIG. 3 and FIG. 12, the kettle seat 22 is provided with an outer shell 2211 for forming the outer contour of the periphery and top of the kettle seat 22, improving the aesthetic 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 the bottom surface of the extension wall 211 abuts against the top surface of the support table 22112, which is conducive to the kettle seat 22 stably supporting the kettle body 21.

[0067] In an embodiment, as shown in FIG. 1 to FIG. 3, the detachable kettle 2 further comprises a lower water valve assembly 23. When the kettle body 21 is connected to the kettle seat 22, the lower water valve assembly 23 is in an open state, and the kettle body 21 and the kettle seat 22 realize 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 seat 22; when the kettle body 21 is separated from the kettle seat 22, the lower water valve assembly 23 is in a closed state to avoid water leakage of the kettle body 21 and the kettle seat 22.

[0068] Specifically, as shown in FIG. 3, the lower water valve assembly 23 comprises a kettle body valve group 231 and a kettle seat valve group 232. The kettle body valve group 231 comprises a first valve body 2311 and a first valve core 2312, and the kettle seat 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, and the kettle seat 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 seat 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 seat 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 seat 22, the first valve core 2312 moves downward to the corresponding lower limit position, and the first valve core 2312 cooperates with the first valve body 2311 to 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 seat 22 flowing out from the second valve body 2321. At this time, the lower water valve assembly 23 is in a closed state.

[0069] In an embodiment, as shown in FIG. 1 and FIG. 8, the main machine 1 further comprises an expansion function module 11, and the kettle seat 22 is provided with an attachment docking module 222. The expansion function module 11 cooperates with the attachment docking module 222 to enable the detachable connection of the kettle seat 22 and the main machine 1.

[0070] Further, as shown in FIG. 1 and FIG. 8, the expansion function module 11 comprises a host waterway docking element 111, and the attachment docking module 222 comprises an 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 detachable kettle 2 is installed on the expansion function module 11, the host waterway docking element 111 is docked with the attachment waterway docking element 2221, so that the host 1 supplies water for the detachable kettle 2, and the host 1 and the detachable kettle 2 are used in cooperation, and the detachable 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 detachable kettle 2 is not installed on the expansion function module 11, and the host 1 works independently and purifies through the filter assembly 171 of the host 1 to provide purified water for drinking.

[0071] Through the above setting mode, the user can first realize the demand of directly drinking purified water through the host 1; secondly, the detachable kettle 2 is connected through the expansion function module 11, and the host 1 is used as the basis to supply water for the detachable kettle 2, so that part of the structure of the detachable kettle 2 is saved, the integration effect is good, and the cost is low.

[0072] Further, as shown in FIG. 1 and FIG. 8, the expansion function module 11 further comprises a host electrical docking element 112, and the attachment docking module 222 further comprises an attachment electrical docking element 2222. When the multifunctional water purifier 100 is in the multifunctional mode, the host electrical docking element 112 is docked with the attachment electrical docking element 2222, the host 1 supplies power for the detachable kettle 2 and / or the host 1 and the detachable kettle 2 perform signal interaction.

[0073] In an embodiment, as shown in FIG. 1 and FIG. 8, the host waterway docking element 111 and the attachment waterway docking element 2221 constitute a water valve assembly, when the host waterway docking element 111 and the attachment waterway docking element 2221 are in the docking state, the host waterway docking element 111 and the attachment waterway docking element 2221 are respectively in the open state, the host 1 and the detachable kettle 2 can realize fluid circulation through the host waterway docking element 111 and the attachment waterway docking element 2221, when the attachment waterway docking element 2221 is separated from the host waterway docking element 111, the host waterway docking element 111 is in the closed state to prevent water in the host 1 from flowing out from the host waterway docking element 111, and the attachment waterway docking element 2221 is in the closed state to prevent water in the detachable kettle 2 from flowing out from the attachment waterway docking element 2221.

[0074] In addition, one of the host electrical docking element 112 and the attachment electrical docking element 2222 is a female end of a coupler, and the other is a male end of the coupler. 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. 1 and 8, the host electrical docking element 112 is the female end of the coupler, and the attachment electrical docking element 2222 is the male end of the coupler, which facilitates docking and avoids the need to make a more complex waterproof structure for the host electrical docking element 112. Specifically, the host electrical docking element 112 includes at least one of a host power supply terminal, a host detection terminal, and a host signal terminal. The host power supply terminal is used to provide power for the detachable kettle. The host detection terminal is used to determine whether the detachable kettle is docked. The host signal terminal is used to send information to the detachable kettle and / or receive information sent by the detachable kettle. In actual product application, different types and quantities of terminals are set according to product requirements. For example, in order to facilitate user installation, the host electrical docking element 112 includes a host power supply terminal, so that it is not necessary to provide an additional socket for the detachable kettle in the installation scenario. For example, in order to save costs and facilitate user operation on the same user interface, the host electrical docking element 112 includes a host signal terminal.

[0075] In an embodiment, the expansion function module 11 is detachably installed on the host 1. When in a single working mode, the expansion function module 11 is in a retracted state, and at least the host waterway docking element 111 and the host electrical docking element 112 in the 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 expansion function module 11 is entirely retracted into the water supply host 1, which embodies the overall aesthetics, avoids bumping during transportation and use, and finally prevents dust and water. As shown in FIGS. 1 and 10, when in a multifunctional working mode, at least the host waterway docking element 111 and the host electrical docking element 112 in the expansion function module 11 are located outside the host 1, so that the multifunctional water machine detachable kettle 2 can be smoothly connected to the expansion function module 11. Preferably, when the multifunctional water purifier 100 is in a multifunctional working mode, at least the host electrical docking element 112 and the host waterway docking element 111 in the expansion function module 11 are installed on the host 1 in a bare state to install the detachable kettle 2.

[0076] In an embodiment, the expansion function module 11 is arranged at the lower side of the host 1. The bottom of the expansion function module 11 can abut against the installation platform. After the detachable kettle 2 is docked, the expansion function module 11 can avoid or even not bear the weight applied by the detachable kettle 2 as much as possible, thereby ensuring that the expansion function module 11 has a small position deformation amount and high docking accuracy during long-term use.

[0077] In another embodiment, as shown in FIG. 1, the expansion function module 11 is arranged on one side wall of the main machine 1 and faces the detachable kettle 2. Specifically, the expansion function module 11 is arranged on the lower part of one side of the main machine 1, and the detachable kettle 2 is inserted into the main machine electric docking element 112 and the main machine waterway docking element 111 of the expansion function module 11 in the left-right direction. In this embodiment, it is worth noting that the expansion function module 11 is fixedly arranged on the main machine 1. The protruding direction of the main machine electric docking element 112 is parallel to the docking direction of the detachable kettle 2, and the protruding direction of the main machine electric docking element 112 is parallel to the bottom surface of the main machine 1.

[0094] In an embodiment, as shown in FIGS. 5 and 7, the multifunctional water purifier 100 further comprises a locking element 31, which can move 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 detachable kettle 2, the kettle seat 22 does not need to be detached, 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, thereby ensuring that the kettle seat 22 can be stably connected to the main machine 1.

[0095] 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.

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.

[0097] Further, as shown in FIGS. 9 and 10, 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.

[0098] Further, as shown in FIGS. 9 and 10, 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.

[0118] 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 water supply port 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.

[0119] In an embodiment, as shown in FIG. 12, the water storage cavity 252 is below the kettle cavity 215, which is beneficial to drain the water in the kettle cavity 215.

[0120] In an embodiment, as shown in FIG. 12, 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.

[0121] Further, as shown in FIG. 12, the bottom of the kettle cavity 215 is in communication with the top of the water storage cavity 252. Specifically, as shown in FIG. 16, 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 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.

[0122] In an embodiment, as shown in FIG. 12, 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.

[0123] Further, as shown in FIG. 9, FIG. 10 and FIG. 12, 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.

[0124] Further, as shown in FIG. 9 and FIG. 12, the kettle seat 22 comprises 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 comprises 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.

[0125] Further, as shown in FIG. 12, 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.

[0126] 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 attachment docking module 222, so that the components are arranged compactly and the space utilization rate is high.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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 contact the water in the water storage cavity 252.

[0131] 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.

[0132] 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 attached waterway docking element 2221.

[0133] 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 attachment waterway docking element 2221 comprises an attachment 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 attachment waterway valve core 22211 to move between the open position and the closed position. When the attachment 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 attachment 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 attachment waterway valve core 22211 to simplify the structure of the attachment waterway docking element 2221.

[0134] In an embodiment, as shown in FIG. 12, 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 size of the purified water tank 13 in the height direction 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 size of the kettle body 21 in the height direction is only affected by the kettle seat 22. Therefore, the capacity of the kettle body 21 is increased by extending the height of the kettle body 21 as much as possible, so that the lowest point of the kettle cavity 215 is lower than or flush with the lowest point of the purified water storage cavity 131. When the detachable 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, that is, 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 avoids 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.

[0135] Further, as shown in FIG. 12, the lowest point of the kettle cavity 215 is below the lowest point of the purified water storage cavity 131, so as to increase the capacity of the kettle cavity 215.

[0136] In an embodiment, the main machine 1 further comprises a second low water level detection mechanism. When the detachable 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, so as to timely supplement water when the purified water tank 13 is short of water.

[0137] Further, as shown in FIG. 12 and FIG. 13, the main machine 1 further comprises a low water level detection box 151, the low water level detection box 151 comprises a containing cavity 1512 which is 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 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 detachable water kettle 2 is connected to the main machine 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.

[0138] Further, as shown in FIG. 12, 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.

[0139] Further, as shown in FIG. 12, 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 detachable water 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 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.

[0140] In an embodiment, as shown in FIG. 12, 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.

[0141] In an embodiment, as shown in FIG. 12, 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 main machine 1, thereby reducing the occupation of the transverse space in the main machine 1.

[0142] Further, as shown in FIG. 12, the cross-sectional area of the accommodating cavity 1512 is smaller than that of the water storage cavity 252, which makes full use of the lateral 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 that of the water storage cavity 252.

[0143] In an embodiment, as shown in FIG. 12, 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.

[0144] Further, as shown in FIGS. 12-14, 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 water supply port 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.

[0145] 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 first position described above, and the position of the second limiting piece 1517 is the second position described above.

[0146] In an embodiment, as shown in FIG. 13 and FIG. 15, the water purifying tank 13 is provided with a tank communication port 132 for communicating with the container cavity 1512 and an intercepting structure 133 for preventing foreign matters in the water storage cavity 131 from entering the container cavity 1512 through the tank communication port 132. 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 causes the need to replace the low water level detection box, increasing the use burden.

[0147] 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 itself, 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 is adjusted by adjusting the spacing between adjacent two 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.

[0148] In an embodiment, the main machine 1 further includes a high water level detection mechanism. When the detachable 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 detachable 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 respectively reach the corresponding preset high water level. 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, without the need to additionally configure a corresponding high water level detection mechanism on the detachable kettle 2, which can simplify the structure of the detachable kettle 2 and reduce the processing cost.

[0149] 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, and the cavity 1522 communicates with the water storage cavity 131 through the fifth through hole 1523. The high water level detection mechanism includes a third float 1521 and a third liquid level sensor in cooperation, and the third float 1521 is located in the cavity 1522.

[0150] In an embodiment, when the detachable 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 detachable 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 it is necessary to respectively set water level detectors for the kettle body and the water purifying tank. In the present scheme, the water purifying tank 13 and the detachable kettle 2 are separated and simultaneously replenished with water, and the water replenishment time is short.

[0151] Further, as shown in FIGS. 9 and 12, when the detachable 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 providing the kettle body 21 with the kettle body communication port 216, the water inlet and outlet of the kettle body 21 can be realized, and it is not necessary to additionally open a water inlet on the kettle body 21, which can simplify the structure of the kettle body 21 and the connection relationship between the detachable kettle 2 and the main machine 1.

[0152] Further, as shown in FIGS. 12 and 13, when the detachable 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 enters the water purifying tank 13 through the water storage cavity 1512. In this way, by providing the water purifying tank 13 with the tank body communication port 132, 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.

[0153] It should be understood that, in the process of replenishing the water purifying tank 13 and the detachable kettle 2 with water, 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 body 21 from the water storage box 25. The gas in the pipeline, the water purifying tank 13 and the water storage box 25 is pressed and discharged upward, which is beneficial to the water level of the water purifying tank and the kettle body reaching balance as soon as possible, so as to increase the accuracy of water level detection.

[0154] In an embodiment, as shown in FIGS. 13 and 18, the multifunctional water purifier 100 further comprises a water collection piece 18. The water purifying tank 13 and the detachable kettle 2 are respectively connected to the water collection piece 18. When the multifunctional water purifier 100 starts to make water, the purified water enters the water purifying tank 13 and the detachable kettle 2 through the water collection piece 18. When the multifunctional water purifier 100 starts to supply water, the water purifying tank 13 and the detachable kettle 2 respectively supply water outward through the water collection piece 18. In the present scheme, by configuring the water collection piece 18, the water inlet and outlet pipelines of the water purifying tank 13 and the detachable kettle 2 are connected, which can reduce the number of pipelines and the number of pipeline joints, simplify the pipeline design, and further reduce the risk of pipeline blockage and the probability of pipeline joint leakage to a certain extent.

[0155] Further, as shown in FIG. 3, FIG. 13 and FIG. 16, the water purifying tank 13 is provided with a tank communicating port 132, and the detachable kettle 2 is provided with a kettle body communicating port 216. The water collecting piece 18 is in communication with the tank communicating port 132 and the kettle body communicating port 216 respectively; the purified water flows into or out of the water purifying tank 13 through the tank communicating port 132, and the purified water flows into or out of the detachable kettle 2 through the kettle body communicating port 216. Specifically, the water purifying tank 13 is matched with the water collecting piece 18 through the tank communicating port 132 to realize the water inlet and outlet of the water purifying tank 13, and the detachable kettle 2 is matched with the water collecting piece 18 through the kettle body communicating port 216 to realize the water inlet and outlet of the detachable kettle 2, the water purifying tank 13 has fewer openings and the water purifying tank 13 has fewer pipes matched therewith, and the detachable kettle 2 has fewer pipes matched therewith, which is conducive to simplifying the pipe design of the multifunctional water purifier 100.

[0156] Further, as shown in FIG. 13, FIG. 16 and FIG. 18, the water collecting piece 18 is further provided with a first connecting port 181 and a second connecting port 182, the first connecting port 181 is in communication with the tank communicating port 132 through a first pipe 191, and the second connecting port 182 is in communication with the kettle body communicating port 216 through a second pipe 192. Of course, if the water collecting piece 18 is close to the tank communicating port 132 or the kettle body communicating port 216, the first pipe 191 or the second pipe 192 can not be provided, or both pipes are not provided, the first connecting port 181 is directly connected with the tank communicating port 132, or the first connecting port 181 is directly connected with a low water level detection box 151 matched with the water purifying tank 13; the second connecting port 182 is directly connected with the attachment docking module 222 of the detachable kettle 2.

[0157] In an embodiment, as shown in FIG. 16 and FIG. 18, the water collecting piece 18 is further provided with a third connecting port 183 and a fourth connecting port 184, the third connecting port 183 is connected with the outlet end of the filter core assembly 171, and the fourth connecting port 184 is used to supply water to the water supply port 14 of the multifunctional water purifier 100. In this way, the water collecting piece 18 can realize the water connection with the water purifying tank 13, the detachable kettle 2, the filter core assembly 171 and the water supply port 14 through the four connecting ports, and the water collecting piece 18 has a simple structure and only needs four water connection relationships, thereby reducing the number of pipes and the number of pipe joints.

[0158] Further, as shown in FIG. 17, the main machine 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.

[0159] In an embodiment, the filter core assembly 171 has a purified water outlet (not shown in the figure), and the water collecting piece 18 is located below the purified water outlet. On the one hand, the water collecting piece 18 is accommodated in the empty space below the filter core assembly 171, so as to reduce the change of the arrangement position of the remaining components in the main machine 1 as much as possible, and on the other hand, the distance between the water collecting piece 18 and the filter core assembly 171 can be shortened, so as to reduce the number of pipelines, reduce the risk of pipeline blockage and the probability of pipeline joint leakage, or shorten the length of the pipeline, reduce the difficulty of pipeline arrangement, reduce the occupied space of the pipeline, and in addition, the water flowing out of the purified water outlet has a certain pressure due to the pressurization of the booster pump or tap water, so as to facilitate the water level of the purified water tank and the kettle to reach balance as soon as possible, so as to increase the accuracy of water level detection.

[0160] Further, as shown in FIGS. 17 and 18, the top wall of the water collecting piece 18 is provided with a third connecting port 183, which is directly connected with the outlet end of the filter core assembly 171. Preferably, the water collecting piece 18 is located directly below the purified water outlet, so as to shorten the distance therebetween, so as to facilitate direct communication.

[0161] In an embodiment, as shown in FIGS. 12, 13 and 16, the tank connecting port 132 of the purified water tank 13, the kettle connecting port 216 of the detachable kettle 2 and the water collecting piece 18 are sequentially arranged from top to bottom. Specifically, the kettle connecting port 216 is lower than the tank connecting port 132, so as to facilitate the detection of the low water level of the whole machine by using the water storage box 25 of the detachable kettle 2 when the multifunctional water purifier 100 is in the first working mode; the water collecting piece 18 is lower than the kettle connecting port 216 and the tank connecting port 132, so that when the purified water tank 13 and the detachable kettle 2 supply water outward through the water supply port 14, if the water level in the purified water tank 13 and the detachable kettle 2 drops to the low water level, the water collecting piece 18 will not flow back because it is lower than the low water level position, and when the user takes hot water, the steam at the water supply port 14 caused by empty pumping can be avoided. Of course, the water collecting piece 18 can also be higher than the kettle connecting port 216 and the tank connecting port 132, and a control valve is configured to prevent backflow, which will also cause the corresponding increase of the joints in the pipeline.

[0162] In an embodiment, as shown in FIGS. 12 and 13, the purified water tank 13 is located above the water collecting piece 18, and the kettle connecting port 216 of the detachable kettle 2, the tank connecting port 132 of the purified water tank 13 and the water collecting piece 18 are sequentially arranged in the left-right direction of the multifunctional water purifier 100, so as to facilitate the arrangement of the pipeline.

The rear end port of the horizontal box body 1514 is in communication with the vertical box body 1513, and the front part of the horizontal box body 1514 is in communication with the first pipeline 191. In the present scheme, by arranging the horizontal box body 1514 on the low water level detection box 151, the spacing between the low water level detection box 151 and the first connecting port 181 in the front-rear direction can be shortened, and the length of the first pipeline 191 can be further shortened.

[0168] Further, as shown in FIG. 13, the bottom wall of the front part of the horizontal box body 1514 is provided with a connecting pipeline 15141, the connecting pipeline 15141 extends downward and is in communication with the first pipeline 191. The arrangement of the connecting pipeline 15141 can shorten the spacing between the low water level detection box 151 and the first connecting port 181 in the up-down direction, and the length of the first pipeline 191 can be further shortened.

[0169] In an embodiment, as shown in FIG. 16 and FIG. 17, the first pump body 161 in the main machine 1 is vertically arranged below the water purifying tank 13, and the third pipeline 193 is connected with the inlet end of the first pump body 161. The arrangement position of the first pump body 161 is optimized, so that the spacing between the fourth connecting port 184 of the water collecting piece 18 and the inlet end of the first pump body 161 in the up-down direction of the multifunctional water purifier 100 is short, which is beneficial to shorten the length of the third pipeline 193. Under the water power provided by the first pump body 161, the water purifying tank 13 and the detachable kettle 2 supply water to the water supply port 14 respectively.

[0170] Further, as shown in FIG. 17, the outlet end of the third pipeline 193 extends upward to be in communication with the bottom of the first pump body 161, which is further beneficial to shorten the length of the third pipeline 193.

[0174] In an embodiment, as shown in FIGS. 16 and 17, the multifunctional water purifier 100 further comprises a heating element 172, and the purified water pumped out by the first pump body 161 is supplied to the water supply port 14 via the heating element 172. Specifically, when the user takes normal temperature water, the heating element 172 does not work, and the purified water flows to the water supply port 14 via the heating element 172; when the user takes hot water, the heating element 172 works, and the purified water flows into the heating element 172, is heated via the heating element 172 to form hot water, and then flows to the water supply port 14.

[0175] Further, as shown in FIGS. 16 and 17, the heating element 172 is located between the transverse box 1514 and the filter core assembly 171, and the bottom of the first pump body 161 is connected with a water outlet pipeline 194, which bypasses the transverse box 1514 to be connected with the bottom of the heating element 172. By optimizing the arrangement position of the heating element 172 and the piping mode of the water outlet pipeline 194, the length of the water outlet pipeline 194 is shortened.

[0176] Further, as shown in FIG. 16, the water outlet pipeline 194 is provided with a drainage component 173, which is used for manual drainage and can be manually opened to 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 of the water supply port 14 fails, the manual drainage can be performed through the drainage component 173 to ensure that the repair work can be carried out smoothly.

[0177] In an embodiment, as shown in FIGS. 16 and 18, the second side wall 1852 of the water collecting piece 18 away from the water supply port 14 is provided with a second connecting port 182, and the second connecting port 182 communicates with the kettle body communication port 216 through a second pipeline 192. By optimizing the positional relationship of the various interfaces of the water collecting piece 18, the integration of multiple pipelines is met, and the miniaturization design of the water collecting piece 18 is ensured as much as possible, and the occupied space of the water collecting piece 18 is reduced.

[0178] Further, as shown in FIG. 16, the second pipeline 192 extends in the horizontal plane. Specifically, the main machine 1 is docked with the detachable kettle 2 through the attachment of the expansion function module 11 and the attachment docking module 222, the input end of the main machine waterway docking element 111 of the 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, so that the second pipeline 192 can be arranged to extend along the horizontal plane, and the second pipeline 192 occupies less vertical space.

[0179] In an embodiment, as shown in FIGS. 18 and 19, the water collecting piece 18 is provided with a water storage cavity 186, which is in communication with the purified water tank 13 and the detachable kettle 2. By providing the water storage cavity 186 on the water collecting piece 18, the fluid can be buffered, and when the multifunctional water purifier 100 is in the state of providing purified water to the purified water tank 13 and the detachable kettle 2, the fluid buffered in the water storage cavity 186 can help to improve the stability of the water outlet of the first connecting port 181 and the second connecting port 182.

[0180] Further, as shown in FIGS. 18 and 19, the water collecting piece 18 is provided with a temperature detection 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 purified water tank 13 and the detachable kettle 2, the purified water tank 13 is located in the main machine shell 12, and the detachable kettle 2 is exposed, which causes the environment temperature of the purified water tank 13 and the detachable kettle 2 to be different, and further causes the water temperature of the purified water tank 13 and the detachable kettle 2 to be different. When the multifunctional water purifier 100 is in the first working mode, the user takes water at the same time from the purified water tank 13 and the detachable kettle 2, and thus it is necessary to detect the water temperature of the mixed water of the purified water tank 13 and the detachable kettle 2. If only an NTC element is configured in the purified water tank 13, the water temperature detection will not be accurate, which causes the water outlet temperature to be too high to cause high-steam, or the water outlet temperature to be too low to meet the user's demand. In the present mode, the purified water tank 13 and the detachable kettle 2 are mixed in the water storage cavity 186 first, and then the temperature of the mixed water in the water storage cavity 186 is preliminarily detected by the temperature detection element 187, and then the water is supplied to the heating element 172, which can improve the accuracy of temperature detection and avoid the problems of high-steam of the heating element 172 and too low water outlet temperature.

[0181] In an embodiment, as shown in FIGS. 18 and 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 turned on to make water, the water flow entering the third connecting port 183 can quickly enter the flow guide groove 1861 due to the low position of the flow guide groove 1861, and then be discharged through the first connecting port 181 and the second connecting port 182, respectively; when the multifunctional water purifier 100 in the first working mode is turned on 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 detachable kettle 2 enters the flow guide groove 1861 through the second connecting port 182, and the water in the flow guide groove 1861 can quickly enter the fourth connecting port 184 in communication therewith to supply water to the first pump body 161 through the fourth connecting port 184.

[0182] Further, as shown in FIGS. 18 and 19, the flow guide groove 1861 includes a first groove body 18611 and a second groove body 18612 in communication with each other, and the first groove body 18611 is located on the side of the water storage cavity 186 close to the detachable kettle 2. The first connecting port 181, the second connecting port 182 and the fourth connecting port 184 are in communication with the first groove body 18611, respectively, 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 supply 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 make water, the water flow entering 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.

[0183] Further, as shown in FIG. 18, the first groove body 18611 includes a first groove wall 186111 connected with the second groove body 18612, and the first groove wall 186111 extends in a downward direction 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.

[0184] In an embodiment, as shown in FIGS. 18 and 19, the water collecting piece 18 includes a water collecting box 1881 and a water collecting cover 1882 detachably connected and sealed to form the water storage cavity 186. The water collecting piece 18 is provided in a split structure to facilitate cleaning of the inner wall of the water collecting piece 18.

[0185] In an embodiment, the water storage cavity 186 has a volume greater than or equal to 18 cm3, which maximizes the use of the free internal space at the bottom of the purified water outlet of the filter cartridge 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.

[0186] In an embodiment, as shown in FIGS. 12 and 16, when the detachable kettle 2 is in a connected state with the main machine 1, the water collection 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 detachable kettle 2 first enters the water collection piece 18, and then flows to the first pump body 161. If the position of the water collection piece 18 is higher than the lower limit position of the first float 2511, when the water in the water collection piece 18 is pumped out, 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 hot water is taken at this time, the empty pumping will also cause steam spraying, which poses a hidden danger. Therefore, the position of the water collection piece 18 is set below the lower limit position of the first float 2511 to avoid empty pumping.

[0187] In an embodiment, as shown in FIG. 1, the main machine 1 further includes a raw water tank 1010. The raw water provided by the raw water tank 1010 is purified by the filter cartridge assembly 171 to form purified water, which is then provided to the purified water tank 13 and the detachable kettle 2. One of the raw water tank 1010 and the detachable kettle 2 is located on the left side of the main machine shell 12, and the other is located on the right side of the main machine shell 12, so as to avoid the size of the multifunctional water purifier 100 in the front-rear direction being too large, which limits the application scenarios of the multifunctional water purifier 100 due to the width of the placement table. Of course, the main machine 1 can also not be provided with the raw water tank 1010, and the main machine 1 can be directly connected to the municipal tap water. Further, the raw water tank 1010 and the detachable kettle 2 are symmetrically arranged about the main machine shell 12, which facilitates short operation distance of the components of the main machine 1, and is more in line with the aesthetic design.

[0188] In an embodiment, 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 a user to hold.
