Description

Technical Field

[0001] The present invention relates to a water boiling device and a water boiling unit thereof. Background Art

[0002] Conventional electric kettles include a base and a kettle body. The base is provided with a lower coupling portion of a coupler, which is configured to be connected to mains electricity. The kettle body is provided with an upper coupling portion of the coupler, which is connected to a heating portion of the kettle body (e.g., a thick film or resistive heater). When the kettle body is placed on the base, the upper coupling portion and the lower coupling portion are coupled to each other, allowing mains electricity to be supplied to the heating portion of the kettle body through the lower coupling portion and the upper coupling portion, thereby heating the water contained in the kettle body. Conventional electric kettles have the disadvantage that the water contained in the kettle body needs to be heated all at once. If too much water is heated at once and the user cannot drink it all within a short period of time (usually half a day), this results in a waste of water resources. If too little water is heated at once and cannot meet the user's needs within a short period of time, the conventional electric kettle requires the user to boil water multiple times, causing a lot of inconvenience.

[0046] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0047] Reference is made to the accompanying drawings of the present invention. Figures 1 to 5E A water boiling device according to a first preferred embodiment of the present invention will be disclosed and explained in the following description, wherein the water boiling device includes a carrying unit 10, a water storage unit 20, and a water boiling unit 30. The water storage unit 20 and the water boiling unit 30 are respectively detachably carried by the carrying unit 10, and when both the water storage unit 20 and the water boiling unit 30 are carried by the carrying unit 10, the water boiling unit 30 is configured to draw water from the water storage unit 20.

[0048] Specifically, the carrying unit 10 includes a carrying seat 11, a first operating part 12, a connecting part 13 and a first pump body 14, wherein the carrying seat 11 defines a carrying side 111, wherein the first operating part 12 is arranged on the carrying seat 11 in a manner that a portion of the first operating part 12 is exposed to the carrying side 111, and the first operating part 12 has a first operating part channel 121, which is connected to the water inlet of the first pump body 14, wherein the connecting part 13 is arranged on the carrying seat 11 in a manner that a portion of the connecting part 13 is exposed to the carrying side 111, and the connecting part 13 has a connecting part channel 131, which is connected to the water outlet of the first pump body 14.

[0049] More specifically, the bearing seat 11 includes a bearing shell 112 and a bottom shell 113 and has an assembly space 114 . The bearing shell 112 and the bottom shell 113 are mounted on each other to form the assembly space 114 between the bearing shell 112 and the bottom shell 113 . The supporting seat 11 defines the supporting side 111 at the upper part of the supporting shell 112, wherein the supporting shell 112 has a first shell through-hole 1121 and a second shell through-hole 1122, and the first shell through-hole 1121 and the second shell through-hole 1122 are respectively connected to the space at the upper part of the supporting shell 112 and the assembly space 114 of the supporting seat 11, wherein the first operating part 12 is installed on the supporting shell 112 in a manner of being located in the assembly space 114 of the supporting seat 11 and exposed to the first shell through-hole 1121 of the supporting shell 112, so that a portion of the first operating part 12 is exposed to the supporting side 111 of the supporting seat 11, and accordingly, the connecting part 13 is installed on the supporting shell 112 in a manner of being located in the assembly space 114 of the supporting seat 11 and exposed to the second shell through-hole 1122 of the supporting shell 112, so that a portion of the connecting part 13 is exposed to the supporting side 111 of the supporting seat 11.

[0050] Preferably, the first shell through-hole 1121 and the second shell through-hole 1122 of the carrying shell 112 are adjacent to each other, so that the first operating portion 12 and the connecting portion 13 are arranged adjacent to each other, which is beneficial to reducing the volume of the water boiling device.

[0051] In addition, the first pump body 14 is arranged in the assembly space 114 of the supporting seat 11. For example, the first pump body 14 is arranged in the assembly space 114 of the supporting seat 11 in a manner of being fixedly mounted on the bottom shell 113, so that the first operating part 12, the connecting part 13 and the first pump body 14 are integrated by the supporting seat 11.

[0052] Now go to the attached Figure 3 、 Figures 5A to 5E The carrier unit 10 further includes a circuit board 15, which is disposed in the assembly space 114 of the carrier base 11, and the first pump body 14 is connected to the circuit board 15. The circuit board 15 may be integrated with various electronic components such as a control switch and an MCU to allow the circuit board 15 to have a control function. For example, the circuit board 15 may be configured to control the operating state of the first pump body 14.

[0053] Furthermore, the carrying shell 112 of the support base 11 is provided with an interactive area 1120 to facilitate user interaction with the water heating device. Specifically, in some embodiments, the interactive area 1120 of the carrying shell 112 can receive user operations to change the operating state of the water heating device, for example, changing the operating time of the first pump 14 or switching the operating state of the water heating unit 30 between an active state and an idle state. In other embodiments, the interactive area 1120 of the carrying shell 112 can display the water level and / or water temperature in the water heating unit 30.

[0054] Continue to refer to the attached Figures 1 to 5E The water storage unit 20 includes a water storage container 21 and a first sealing portion 22. The water storage container 21 has a water storage space 211 and a first drainage channel 212 connected to the water storage space 211. The first sealing portion 22 is operably mounted on the first drainage channel 212 of the water storage container 21. When the water storage unit 20 is carried by the carrier 11 on the carrying side 111, the first operating portion 12 operates the first sealing portion 22 to open the first drainage channel 212 of the water storage container 21. At this time, the first operating portion channel 121 of the first operating portion 12 is connected to the water storage space 211 through the first drainage channel 212 of the water storage container 21. When the water storage unit 20 is removed from the carrier 11, the first sealing portion 22 automatically closes the first drainage channel 212 of the water storage container 21 to prevent water stored in the water storage space 211 of the water storage container 21 from leaking through the first drainage channel 212 of the water storage container 21.

[0055] In the attached Figures 1 to 5E In this particular example of the water boiler of the present invention, the support base 11 defines a support side 111 on the upper portion of the support shell 112. Therefore, the water storage unit 20 is supported by the support base 11 on the support side 111, positioned on the upper portion of the support shell 112. When the water storage unit 20 is positioned on the upper portion of the support shell 112 with the first operating portion 12 aligned with the first sealing portion 22, at least a portion of the first operating portion 12 can extend into the first drainage channel 212 of the water storage container 21, thereby operating the first sealing portion 22 to open the first drainage channel 212 of the water storage container 21. Furthermore, the first operating portion 12 serves to position the water storage unit 20, preventing lateral movement relative to the support base 10.

[0056] Specifically, now turn to the attached Figure 3 and Figure 4AThe first sealing portion 22 includes a first connecting rod 221, a first sealing element 222 and a first resetting element 223, wherein the top end of the first connecting rod 221 is maintained in the water storage space 211 of the water storage container 21, and the bottom end of the first connecting rod 221 extends to the first drainage channel 212 of the water storage container 21, wherein the first sealing element 222 is arranged at the top end of the first connecting rod 221, wherein the top end of the first resetting element 223 abuts against the water storage container 21, and the bottom end of the first resetting element 223 abuts against the bottom end of the first connecting rod 221, so that the first resetting element 223 can keep the first sealing element 222 in a position to close the first drainage channel 212 of the water storage container 21, and after the position of the first sealing element 222 changes, the first resetting element 223 has a tendency to restore the first sealing element 222 to a position to close the first drainage channel 212 of the water storage container 21.

[0057] For example, in the attached Figures 1 to 5E In this specific example of the water boiling device of the present invention, the first resetting element 223 can cause the bottom wall of the first sealing element 222 to conform to the inner wall of the water storage container 21, which forms the water storage space 211, so that the first sealing element 222 is retained in a position that closes the first drainage channel 212 of the water storage container 21. Alternatively, in other examples of the water boiling device of the present invention, the first resetting element 223 can cause the outer wall of the first sealing element 222 to conform to the inner wall of the water storage container 21, which forms the first drainage channel 212, so that the first sealing element 222 is retained in a position that closes the first drainage channel 212 of the water storage container 21.

[0058] When the water storage unit 20 is positioned on the upper portion of the carrying housing 112 with the first operating portion 12 aligned with the first sealing portion 22, the first operating portion 12 pushes the first connecting rod 221 upward, which in turn drives the first sealing element 222 upward, opening the first drainage channel 212 of the water storage container 21. Simultaneously, the first connecting rod 221 and the water storage container 21 compress the first reset element 223, causing it to elastically deform and accumulate elastic potential energy. Accordingly, when the water storage unit 20 is removed from the upper portion of the carrying housing 112, the first operating portion 12 moves away from the bottom of the first connecting rod 221. The first reset element 223, returning to its initial position, pushes the first connecting rod 221 downward, driving the first sealing element 222 downward, closing the first drainage channel 212 of the water storage container 21.

[0059] Continue to refer to the attached Figure 4A The water storage container 21 has at least one first top abutting portion 213, which is located in the first drainage channel 212 of the water storage container 21, wherein the bottom end of the first connecting rod 221 has at least one first bottom abutting portion 2211, wherein the first reset element 223 is sleeved on the first connecting rod 221, and the top end of the first reset element 223 abuts against the first top abutting portion 213 of the water storage container 21, and the bottom end of the first reset element 223 abuts against the first bottom abutting portion 2211 of the first connecting rod 221, so that the first reset element 223 is reliably held between the first top abutting portion 213 of the water storage container 21 and the first bottom abutting portion 2211 of the first connecting rod 221.

[0060] It is worth mentioning that the number of the first top abutting portions 213 of the water storage container 21 and the number of the first bottom abutting portions 2211 of the first connecting rod 221 are not limited in the water boiling device of the present invention. For example, the number of the first top abutting portions 213 of the water storage container 21 is two or more, and these first top abutting portions 213 are distributed at intervals from each other, so that the top of the first reset element 223 has at least two positions abutting against the water storage container 21, and the number of the first bottom abutting portions 2211 of the first connecting rod 221 is two or more. Some of the first bottom end abutment portions 213 are distributed at intervals from each other, so that the bottom end of the first reset element 223 has at least two positions abutting the bottom end of the first connecting rod 221, so that no matter when the first operating portion 12 pushes the first connecting rod 221 upward or when the first reset element 223 pushes the first connecting rod 221 downward, the first sealing portion 22 can prevent the first connecting rod 221 and the first reset element 223 from tilting, so as to allow the first sealing element 222 to reliably close the first drainage channel 212 of the water storage container 21.

[0061] Continue to refer to the attached Figure 3 and Figure 4AThe water storage container 21 further includes a stabilizing ring 214 having an annular through-hole 2141. The stabilizing ring 214 is connected to the first top abutment portion 213, so that the first top abutment portion 213 retains the stabilizing ring 214 within the first drainage channel 212 of the water storage container 21. The middle portion of the first connecting rod 221 is movably retained within the annular through-hole 2141 of the stabilizing ring 214, so that the stabilizing ring 214 maintains the upward and downward movement of the first connecting rod 221. In other words, the stabilizing ring 214 is configured to prevent the first connecting rod 221 from deflecting during its upward and downward movement, thereby ensuring that the first sealing element 222 can reliably seal the first drainage channel 212 of the water storage container 21.

[0062] It is worth mentioning that the manner in which the first sealing element 222 is arranged at the top end of the first connecting rod 221 is not limited in the water boiling device of the present invention. Figures 1 to 5E In the illustrated example of the water boiling device, the first sealing element 222 is mounted on the top end of the first connecting rod 221 .

[0063] Specifically, the first sealing element 222 has a first fixing hole 2221 , and the top end of the first connecting rod 221 is installed in the first fixing hole 2221 of the first sealing element 222 , so as to set the first sealing element 222 at the top end of the first connecting rod 221 .

[0064] Preferably, the first sealing element 222 is elastic. For example, the first sealing element 222 may be made of rubber or silicone, wherein the cross-sectional size of the first fixing hole 2221 of the first sealing element 222 is slightly smaller than the cross-sectional size of the top end of the first connecting rod 221, so that after the top end of the first connecting rod 221 is installed in the first fixing hole 2221 of the first sealing element 222, the first sealing element 222 can be restrained at the top end of the first connecting rod 221, so as to allow the first sealing element 222 to be reliably set at the top end of the first connecting rod 221.

[0065] More preferably, the first fixing hole 2221 of the first sealing element 222 is a through hole, and the top of the first connecting rod 221 has a first positioning groove 2212. After installing the top of the first connecting rod 221 in the first fixing hole 2221 of the first sealing element 222, a part of the first sealing element 222 is positioned in the first positioning groove 2212 of the first connecting rod 221, thereby further ensuring that the first sealing element 222 is reliably set at the top of the first connecting rod 221.

[0066] Continue to refer to the attached Figure 3 and Figure 4A The water storage container 21 further has a first extension ring 215, which integrally extends downward from the middle of the bottom wall of the water storage container 21 to extend the length of the first drainage channel 212, wherein when the first sealing portion 22 is in a position to close the first drainage channel 212 of the water storage container 21, the bottom end of the first connecting rod 221 of the first sealing portion 22 is completely accommodated in the first drainage channel 212 of the water storage container 21, so that: on the one hand, when the user normally uses the water storage unit 20, the water storage unit 20 makes the first sealing portion 22 invisible, and on the other hand, when the water storage unit 20 is placed on the supporting seat 11, the first operating portion 12 can smoothly push the first connecting rod 221 of the first sealing portion 22 upward.

[0067] Preferably, the water storage container 21 further has a second extension ring 216 , which integrally extends downward from the edge of the bottom wall of the water storage container 21 , so as to stably place the water storage unit 20 on the supporting shell 112 or a desktop.

[0068] Preferably, the water storage container 21 further has a third extension ring 217 and a first positioning space 218, the third extension ring 217 extends downward from the middle of the bottom wall of the water storage container 21 as a whole, and the third extension ring 217 is located on the outside of the first extension ring 215 to form the first positioning space 218 between the first extension ring 215 and the third extension ring 217.

[0069] Continue to refer to the attached Figure 3 、 Figure 4A 、 Figures 5A to 5EThe carrier shell 112 has a first shell protrusion 1123, and the first shell through-hole 1121 is formed in the first shell protrusion 1123. The first operating portion 12 further includes a first operating body 122 and a first mounting ring 123, and a first avoidance groove 124. The first mounting ring 123 surrounds the outer side of the first operating body 122 in such a manner that the bottom of the first mounting ring 123 is connected to the first operating body 122, thereby forming the first avoidance groove 124 between the first operating body 122 and the first mounting ring 123, wherein the first operating portion channel 121 is formed in the first operating body 122. The first mounting ring 123 of the first operating portion 12 is mounted on the first shell protrusion 1123 of the carrier shell 112, and the first operating body 122 and the first avoidance groove 124 correspond to the first shell through-hole 1121 of the carrier shell 112. When the water storage unit 20 is arranged on the upper part of the supporting shell 112 in such a manner that the first operating part 12 is aligned with the first sealing part 22, the first extension ring 215 of the water storage container 21 extends into the first avoidance groove 124 of the first operating part 12. At the same time, the first shell protrusion 1123 of the supporting shell 112 extends into the first positioning space 218 of the water storage container 21, and the first operating body 122 of the first operating part 12 extends into the first drainage channel 212 of the water storage container 21, so that the first operating body 122 of the first operating part 12 pushes the first connecting rod 221 upward, and the first connecting rod 221 drives the first sealing element 222 to move upward to open the first drainage channel 212 of the water storage container 21, and the first connecting rod 221 and the water storage container 21 squeeze the first reset element 223 to cause it to generate elastic deformation to accumulate elastic potential energy.

[0070] Continue to refer to the attached Figure 3 、 Figure 4A 、 Figures 5A to 5E The carrying unit 10 further includes a first sealing gasket 18 , which is disposed between the carrying shell 112 and the first mounting ring 123 of the first operating portion 12 to increase the sealing between the carrying shell 112 and the first operating portion 12 .

[0071] Now go to the attached Figure 3The water storage unit 20 further includes a water filtration unit 23, which further includes a carrier 231 and a filter element 232. The carrier 231 has a carrier space 231 and at least one carrier channel 232 at the bottom of the carrier 231, connected to the carrier space 231. The filter element 232 is disposed at the bottom of the carrier space 231 of the carrier 231. The carrier 231 is detachably disposed at the opening of the water storage container 21. After raw water is contained in the carrier space 231 of the carrier 231, it is filtered by the filter element 232 based on the principle of gravity as it passes through the filter element 232, forming purified water. The purified water is then allowed to enter the water storage space 211 of the water storage container 21 through the carrier channel 232 of the carrier 231.

[0072] Now go to the attached Figure 3 and Figure 4B The water boiling unit 30 includes a water boiling container 31 and a closing valve 32. The water boiling container 31 has a water boiling space 311 and a mounting hole 312 connected to the water boiling space 311. The closing valve 32 is mounted in the mounting hole 312 of the water boiling container 31. When the water boiling unit 30 is carried by the carrier 11 on the carrying side 111, the connecting portion 13 automatically connects to the closing valve 32, allowing the connecting portion channel 131 of the connecting portion 13 to communicate with the water boiling space 311 of the water boiling container 31 through the closing valve 32.

[0073] In the attached Figures 1 to 5E In this particular example of the water boiling device of the present invention, the carrier 11 defines a carrier side 111 on the upper portion of the carrier shell 112. Therefore, the water boiling container 30 is supported by the carrier 11 on the carrier side 111, being placed on the upper portion of the carrier shell 112 of the carrier 11. When the water boiling unit 30 is positioned on the upper portion of the carrier shell 112 with the connecting portion 13 aligned with the closing valve 32, a portion of the connecting portion 13 can extend into the closing valve 32, allowing the connecting portion 13 to automatically connect to the closing valve 32, thereby enabling the connecting portion passage 131 of the connecting portion 13 to communicate with the water boiling space 311 of the water boiling container 31 through the closing valve 32. Optionally, in other examples of the water boiling device of the present invention, when the water boiling unit 30 is disposed on the upper portion of the carrying shell 112 in such a manner that the connecting portion 13 is aligned with the closing valve 32, a portion of the closing valve 32 can extend into the connecting portion channel 131 of the connecting portion 13, thereby enabling the connecting portion channel 131 of the connecting portion 13 to communicate with the water boiling space 311 of the water boiling container 31 through the closing valve 32.

[0074] Continue to refer to the attached Figure 4B The closing valve 32 further includes a valve stem 321, a valve seat 322, a first closing element 323, and a return element 324. The valve stem 321 has a cylindrical space 3211 and at least one top opening 3212 and a bottom opening 3213 connected to the cylindrical space 3211. The valve stem 321 is mounted in the mounting hole 312 of the water boiling container 31, and the top opening 3212 of the valve stem 321 is connected to the water boiling space 311 of the water boiling container 31. The valve seat 322 has a valve seat passage 3221, which is mounted in the bottom opening 3213 of the valve stem 321 and is connected to the cylindrical space 3211 of the valve stem 321. The first closing element 323 is movably mounted in the cylindrical space 3211 of the valve stem 321. The top end of the return element 324 abuts against the inner wall of the valve column 321 , and the bottom end of the return element 324 abuts against the first closing element 323 . The initial state of the return element 324 is to keep the first closing element 323 in the position of closing the valve seat channel 3221 of the valve seat 322 .

[0075] When the water heating unit 30 is installed on the upper part of the carrying shell 112 in a manner such that the connecting portion 13 is aligned with the closing valve 32, the top end of the connecting portion 13 is inserted into the valve seat channel 3221 of the valve seat 322, thereby automatically connecting the connecting portion 13 and the closing valve 32, and communicating with the connecting portion channel 131 of the connecting portion 13 and the valve seat channel 3221 of the valve seat 322. When the first pump body 14 starts to operate and pumps the water stored in the water storage unit 20 into the valve seat channel 3221 of the valve seat 322, the first pump body 14 increases the water pressure of the water pumped into the valve seat channel 3221 of the valve seat 322. Moreover, the upward thrust exerted on the first closing element 323 by the water pumped into the valve seat channel 3221 of the valve seat 322 is greater than the downward thrust exerted on the first closing element 323 by the return element 324. Therefore, the first closing element 323 moves within the column space 3211 of the valve stem 321, allowing the valve seat channel 3221 of the valve seat 322 and the column space 3211 of the valve stem 321 to communicate with each other. At this time, the water stored in the water storage unit 20 can be pumped into the water heating space 311 of the water heating container 31. When the first pump body 14 stops working, the return element 324 pushes the first closing element 323 downward when returning to the initial state, so that the first closing element 323 closes the valve seat channel 3221 of the valve seat 322 again, thereby preventing the water pumped into the water boiling space 311 of the water boiling container 31 from flowing back.

[0076] Preferably, the valve seat 322 is elastic. For example, the valve seat 322 can be made of rubber or silicone, wherein the cross-sectional size of the valve seat channel 3221 of the valve seat 322 is slightly smaller than the cross-sectional size of the connecting part 13, so that when the valve seat channel 3221 of the valve seat 322 is inserted into the top end of the connecting part 13, the connecting part 13 can expand the valve seat 322 to the surrounding areas and increase the sealing between the valve seat 322 and the connecting part 13, so as to prevent the water pumped into the connecting part channel 131 of the connecting part 13 and the valve seat channel 3221 of the valve seat 322 from leaking through the connecting position between the valve seat 322 and the connecting part 13.

[0077] Preferably, in the attached Figures 1 to 5EIn this specific example of the water boiling device of the present invention, the first closing element 323 of the closing valve 32 is spherical, and the first closing element 323 moves in the cylindrical space 3211 of the valve column 321 by moving up and down. That is, when the first closing element 323 moves upward, the first closing element 323 opens the valve seat channel 3221 of the valve seat 322 and allows the valve seat channel 3221 of the valve seat 322 and the cylindrical space 3211 of the valve column 321 to communicate. Correspondingly, when the first closing element 323 moves downward, the first closing element 323 closes the valve seat channel 3221 of the valve seat 322 and prevents the valve seat channel 3221 of the valve seat 322 from communicating with the cylindrical space 3211 of the valve column 321.

[0078] Optionally, in other examples of the water boiling device of the present invention, the first closing element 323 of the closing valve 32 is in a sheet shape, and the first closing element 323 moves in the cylindrical space 3211 of the valve column 321 in such a way that a part (for example, an edge part) of the first closing element 323 deforms upward and downward, that is, when a part of the first closing element 323 deforms upward, the first closing element 323 opens the valve seat channel 3221 of the valve seat 322 and allows the valve seat channel 3221 of the valve seat 322 and the cylindrical space 3211 of the valve column 321 to communicate with each other; correspondingly, when a part of the first closing element 323 deforms downward, the first closing element 323 closes the valve seat channel 3221 of the valve seat 322 and prevents the valve seat channel 3221 of the valve seat 322 from communicating with the main body space 3211 of the valve column 321.

[0079] Continue to refer to the attached Figure 3 and Figure 4B The closing valve 32 further includes a second closing element 325. The second closing element 325 is configured to open or close the top opening 3212 of the valve column 321 to prevent water pumped into the water heating space 311 of the water heating container 31 from flowing back into the column space 3211 of the valve column 321. In this manner, on the one hand, the closing effect of the closing valve 32 is improved to prevent water from the water heating container 31 from flowing out through the closing valve 32 when the water heating unit 30 is removed from the supporting base 11. On the other hand, the second closing element 325 prevents the water retained in the column space 3211 of the valve column 321 from being heated, thereby serving as the metal return element 324.

[0080] Furthermore, the second closing element 325 includes a closing portion 3251 and a fitting portion 3252 integrally extending from the closing portion 3251. The fitting portion 3252 is mounted on the valve post 321, and the closing portion 3251 is adapted to be attached to the valve post 321 in a changeable manner. Thus, the second closing element 325 opens or closes the top opening 3212 of the valve post 321 by allowing the closing portion 3251 to change its state. For example, when the edge of the closing portion 3251 of the second closing element 325 is tilted upward, the second closing element 325 opens the top opening 3212 of the valve post 321. Accordingly, when the closing portion 3251 of the second closing element 325 returns to being flat, the second closing element 325 closes the top opening 3212 of the valve post 321. It can be understood that in order to enable the state of the closing portion 3251 of the second closing element 325 to change and allow the edge of the closing portion 3251 to switch between an upturned state and a flat state, the second closing element 325 is made of a flexible material.

[0081] Furthermore, the valve column 321 has an assembly hole 3214, which extends from the top of the valve column 321 to the column space 3211, wherein the assembly portion 3252 of the second closing element 325 is reliably mounted in the assembly hole 3214 of the valve column 321. When the edge of the closing portion 3251 of the second closing element 325 switches between an upturned state and a flat state, the assembly relationship between the valve column 321 and the second closing element 325 can prevent the second closing element 325 from separating from the valve column 321, thereby ensuring the reliability of the closing valve 32.

[0082] Continue to refer to Figures 2 to Figure 5EThe carrier unit 10 further includes a lower coupler 16 having a lower coupler through-hole 161. The lower coupler 16 is disposed in the second housing through-hole 1122 of the carrier shell 112 of the carrier base 11 such that the portion of the connection portion 13 exposed to the carrier side 111 is retained in the lower coupler through-hole 161. The lower coupler 16 is also connected to the circuit board 15. Accordingly, the water heating unit 30 further includes an upper coupler 33 having an upper coupler through-hole 331. The upper coupler 33 is disposed at the bottom of the water heating container 31 such that the closing valve 32 is retained in the upper coupler through-hole 331. The upper coupler 33 is also connected to a heating element 313 of the water heating container 31. When the water boiling unit 30 is carried on the carrying side 111 by the carrying base 11, the upper coupler 33 and the lower coupler 16 can be coupled to allow commercial power to be sequentially supplied to the heating element 313 via the circuit board 15, the lower coupler 16, and the upper coupler 33. The heat generated by the heating element 313 heats the water pumped into the water boiling space 311 of the water boiling container 31.

[0083] Preferably, refer to the attached Figure 4B The connecting portion 13 has a contact ring 132. The carrying unit 10 further includes a buffer spring 17, which is fitted onto the connecting portion 13. The top end of the buffer spring 17 contacts the contact ring 132 of the connecting portion 13, while the bottom end of the buffer spring 17 contacts the lower coupler 16, thereby suspending the connecting portion 13 in the lower coupler through-hole 161 of the lower coupler 16. When the water heating unit 30 is mounted on the upper portion of the carrying housing 112 with the connecting portion 13 aligned with the closing valve 32, the buffer spring 17 allows the connecting portion 13 to float up and down, thereby enhancing the sealing between the connecting portion 13 and the valve seat 322.

[0084] Attachment Figures 5A to 5E The figure shows the process of using the water boiling device.

[0085] Reference Attachment Figure 5A After the raw water is poured into the carrier space 231 of the carrier 231 of the water filter part 23, based on the principle of gravity, the raw water can be filtered by the water filter 232 to form clean water when passing through the filter element 232, and the clean water is allowed to enter the water storage space 211 of the water storage container 21 through the carrier channel 2312 of the carrier 231.

[0086] Reference Attachment Figure 5A and Figure 5BWhen the water storage unit 20 is arranged on the upper part of the carrying shell 112 in a manner that the first operating part 12 is aligned with the first sealing part 22, the first extension ring 215 of the water storage container 21 extends into the first avoidance groove 124 of the first operating part 12. At the same time, the first shell protrusion 1123 of the carrying shell 112 extends into the first positioning space 218 of the water storage container 21, and the first operating body 122 of the first operating part 12 extends into the first drainage channel 212 of the water storage container 21, so that the first operating part 12 can be used to discharge the liquid. The main body 122 pushes the first connecting rod 221 of the first sealing part 22 upward, and the first connecting rod 221 drives the first sealing element 222 to move upward to open the first drainage channel 212 of the water storage container 21. At this time, the first operating part channel 121 of the first operating part 12 is connected to the water storage space 211 of the water storage container 21 through the first drainage channel 212 of the water storage container 21, and the first connecting rod 221 and the water storage container 21 squeeze the first reset element 223 to cause it to generate elastic deformation to accumulate elastic potential energy.

[0087] Reference Attachment Figure 5C and Figure 5D When the water heating unit 30 is disposed on the upper portion of the carrier shell 112 in such a manner that the connecting portion 13 is aligned with the closing valve 32, the upper coupler 33 and the lower coupler 16 are coupled, and a portion of the connecting portion 13 is inserted into the valve seat channel 3221 of the valve seat 322 of the closing valve 32, allowing the connecting portion channel 131 of the connecting portion 13 and the valve seat channel 3221 of the valve seat 322 to communicate with each other.

[0088] Reference Attachment Figure 5EWhen the first pump body 14 starts to work and pumps the water stored in the water storage unit 20 into the valve seat channel 3221 of the valve seat 322, the first pump body 14 increases the water pressure of the water pumped into the valve seat channel 3221 of the valve seat 322, and the upward thrust exerted by the water pumped into the valve seat channel 3221 of the valve seat 322 on the first closing element 323 is greater than the downward thrust exerted by the return element 324 on the first closing element 323. Therefore, the first closing element 323 is opened. The valve stem 323 moves upward within the cylindrical space 3211 of the valve stem 321, allowing the valve seat passage 3221 of the valve seat 322 to communicate with the cylindrical space 3211 of the valve stem 321. Simultaneously, the edge of the closing portion 3251 of the second closing element 325 tilts upward to open the top opening 3212 of the valve stem 321. At this point, water stored in the water storage space 211 of the water storage container 21 is pumped into the water heating space 311 of the water heating container 31 by the first pump body 14. It will be appreciated that the amount of water pumped into the water heating space 311 of the water heating container 31 can be controlled by controlling the operating time of the first pump body 14.

[0089] Attachment 6A to 9C A water heating device according to a second preferred embodiment of the present invention, and Figures 1 to 5E The water heating device shown is different in that 6A to 9C In this preferred example of the water boiling device of the present invention, the carrier unit 10 further includes a second operating portion 101, a second pump body 102, and a water spout 103. The second operating portion 101 is disposed on the carrier shell 112 of the carrier base 11, with a portion of the second operating portion 101 exposed to the carrier side 111. The second operating portion 101 has a second operating portion channel 1011 that communicates with the water inlet of the second pump body 102. The water spout 103 is disposed on the carrier base 11 and communicates with the water outlet of the second pump body 102. The water spout 103 can be held in a high position by the carrier base 11, making it easier for a user to dispense water from the spout 103.

[0090] Specifically, the carrying shell 112 has a third shell through-hole 1124, which is connected to the space above the carrying shell 112 and the assembly space 114 of the carrying seat 11, wherein the second operating part 101 is installed on the carrying shell 112 in a manner of being located in the assembly space 114 of the carrying seat 11 and exposed to the third shell through-hole 1124 of the carrying shell 112, so that a portion of the second operating part 101 is exposed to the carrying side 111 of the carrying seat 11.

[0091] The water boiling container 31 has a second drainage channel 314 that communicates with the water boiling space 311. The water boiling unit 30 further includes a second sealing portion 34 that is operably mounted on the second drainage channel 314 of the water boiling container 31. When the water boiling unit 30 is positioned on the upper portion of the carrying housing 112 with the second operating portion 101 aligned with the second sealing portion 34, the second operating portion 101 can extend into the second drainage channel 314 of the water boiling container 31 to operate the second sealing portion 34, thereby opening the second drainage channel 314 of the water boiling container 31. Furthermore, the second operating portion 101 serves as a positioning mechanism to prevent lateral movement of the water boiling unit 30 relative to the carrying unit 10. When the water boiling unit 30 is removed from the supporting base 11 , the second sealing portion 34 automatically closes the second drainage channel 314 of the water boiling container 31 to prevent water in the water boiling space 311 of the water boiling container 31 from leaking through the second drainage channel 314 of the water boiling container 31 .

[0092] Specifically, now turn to the attached Figures 8 to 9C The second sealing portion 34 includes a second connecting rod 341, a second sealing element 342, and a second restoring element 343. The top end of the second connecting rod 341 is retained in the water boiling space 311 of the water boiling container 31, and the bottom end of the second connecting rod 341 extends to the second drainage channel 314 of the water boiling container 31. The second sealing element 342 is provided at the top end of the second connecting rod 341. The top end of the second restoring element 343 abuts against the water boiling container 31, and the bottom end of the second restoring element 343 abuts against the bottom end of the second connecting rod 341. In this way, the second restoring element 343 can maintain the second sealing element 342 in a position that closes the second drainage channel 314 of the water boiling container 31. After the position of the second sealing element 342 changes, the second restoring element 343 tends to restore the second sealing element 342 to a position that closes the second drainage channel 314 of the water boiling container 31.

[0093] For example, in the attached 6A to 9CIn this specific example of the water boiling device of the present invention, the second resetting element 343 can cause the bottom wall of the second sealing element 342 to conform to the inner wall of the water boiling container 31, which forms the water boiling space 311, thereby maintaining the second sealing element 342 in a position that closes the second drainage channel 314 of the water boiling container 31. Alternatively, in other examples of the water boiling device of the present invention, the second resetting element 343 can cause the outer wall of the second sealing element 342 to conform to the inner wall of the water boiling container 31, which forms the second drainage channel 314, thereby maintaining the second sealing element 342 in a position that closes the second drainage channel 314 of the water boiling container 31.

[0094] When the water boiling unit 30 is positioned on the upper portion of the carrying case 112 with the second operating portion 101 aligned with the second sealing portion 34, a portion of the second operating portion 101 pushes the second connecting rod 341 upward, which in turn drives the second sealing element 342 upward, opening the second drain channel 314 of the water boiling container 31. Simultaneously, the second connecting rod 341 and the water boiling container 31 compress the second restoring element 343, causing it to elastically deform and accumulate elastic potential energy. Accordingly, when the water boiling unit 30 is removed from the upper portion of the carrying case 112, the second operating portion 101 moves away from the bottom of the second connecting rod 341. The second restoring element 343, returning to its original position, pushes the second connecting rod 341 downward, driving the second sealing element 342 downward, closing the second drain channel 314 of the water boiling container 31.

[0095] Continue to refer to the attached Figure 9C The water boiling container 31 has at least one second top abutting portion 315 located in the second drainage channel 314 of the water boiling container 31 , wherein the bottom end of the second connecting rod 341 has at least one second bottom abutting portion 3411 , wherein the second restoring element 343 is fitted onto the second connecting rod 341 , and the top end of the second restoring element 343 abuts against the second top abutting portion 315 of the water boiling container 31 , and the bottom end of the second restoring element 343 abuts against the second bottom abutting portion 3411 of the second connecting rod 341 , thereby reliably holding the second top abutting portion 315 of the water boiling container 31 and the second bottom abutting portion 3411 of the second connecting rod 341 .

[0096] Preferably, the second top abutment portion 315 of the water boiling container 31 is annular, and the number of the second bottom abutment portions 3411 of the second connecting rod 341 is two or more. In this way, the bottom end of the second reset element 343 has at least two positions abutting the bottom end of the second connecting rod 341. Therefore, whether the second operating portion 101 pushes the second connecting rod 341 upward or the second reset element 343 pushes the second connecting rod 341 downward, the second sealing portion 34 can prevent the second connecting rod 341 and the second reset element 343 from tilting, so as to allow the second sealing element 342 to reliably close the second drainage channel 314 of the water boiling container 31.

[0097] It is worth mentioning that the manner in which the second sealing element 342 is disposed at the top end of the second connecting rod 341 is not limited in the water boiling device of the present invention. 6A to 9C In the illustrated example of the water boiling device, the second sealing element 342 is mounted on the top end of the second connecting rod 341 .

[0098] Specifically, the second sealing element 342 has a second fixing hole 3421 , and the top end of the second connecting rod 341 is installed in the second fixing hole 3421 of the second sealing element 342 , so that the second sealing element 342 is disposed at the top end of the second connecting rod 341 .

[0099] Preferably, the second sealing element 342 is elastic. For example, the second sealing element 342 can be made of rubber or silicone, wherein the cross-sectional size of the second fixing hole 3421 of the second sealing element 342 is slightly smaller than the cross-sectional size of the top end of the second connecting rod 341, so that after the top end of the second connecting rod 341 is installed in the second fixing hole 3421 of the second sealing element 342, the second sealing element 342 can be restrained at the top end of the second connecting rod 341 to allow the second sealing element 342 to be reliably set at the top end of the second connecting rod 341.

[0100] More preferably, the second fixing hole 3421 of the second sealing element 342 is a through hole, and the top of the second connecting rod 341 has a second positioning groove 3412. After installing the top of the second connecting rod 341 in the second fixing hole 3421 of the second sealing element 342, a part of the second sealing element 342 is positioned in the second positioning groove 3412 of the second connecting rod 341, thereby further ensuring that the second sealing element 342 is reliably set at the top of the second connecting rod 341.

[0101] Continue to refer to the attached Figure 9CThe water boiling container 31 further has a fourth extension ring 316 that integrally extends downward from the bottom wall of the water boiling container 31 to extend the length of the second drainage channel 314. When the second sealing portion 34 is in a position to seal the second drainage channel 314 of the water boiling container 31, the bottom end of the second connecting rod 341 of the second sealing portion 34 is completely accommodated in the second drainage channel 314 of the water boiling container 31. In this way, on the one hand, when a user normally uses the water boiling unit 30, the water boiling unit 30 makes the second sealing portion 34 invisible. On the other hand, when the water boiling unit 30 is placed on the supporting base 11, the second operating portion 101 can smoothly push the second connecting rod 341 of the second sealing portion 34 upward.

[0102] The water heating container 31 further has a second positioning space 317, which surrounds the fourth extension ring 316. The carrier shell 112 has a second housing protrusion 1125, and the third housing through-hole 1124 is formed in the second housing protrusion 1125. The second operating portion 101 further includes a second operating body 1012 and a second mounting ring 1013, and a second avoidance groove 1014. The second mounting ring 1013 surrounds the outside of the second operating body 1012, with the bottom of the second mounting ring 1013 connected to the second operating body 1012, forming the second avoidance groove 1014 between the second operating body 1012 and the second mounting ring 1013. The second operating portion channel 1011 is formed in the second operating body 1012. When the water boiling unit 30 is mounted on the upper portion of the carrying shell 112 with the second operating portion 101 aligned with the second sealing portion 34, the fourth extension ring 316 of the water boiling container 31 extends into the second avoidance groove 1014 of the second operating portion 101. Simultaneously, the second housing protrusion 1125 of the carrying shell 112 extends into the second positioning space 317 of the water boiling container 31. The second operating body 1012 of the second operating portion 101 extends into the second drainage channel 314 of the water boiling container 31. As a result, the second operating body 1012 of the second operating portion 101 pushes the second connecting rod 341 upward. The second connecting rod 341 drives the second sealing element 342 upward to open the second drainage channel 314 of the water boiling container 31. Furthermore, the second connecting rod 341 and the water boiling container 31 compress the second restoring element 343, causing it to elastically deform and retain its elastic potential energy. Accordingly, when the water boiling unit 30 is moved away from the upper portion of the carrying shell 112, the second operating portion 101 is moved away from the bottom of the second connecting rod 341. The second reset element 343 pushes the second connecting rod 341 downward when returning to its initial state. The second connecting rod 341 drives the second sealing element 342 to move downward, thereby closing the second drainage channel 314 of the water boiling container 31.

[0103] Continue to refer to the attached Figure 9C The carrying unit 10 further includes a second sealing gasket 104 , which is disposed between the carrying shell 112 and the second mounting ring 1013 of the second operating portion 101 to increase the sealing between the carrying shell 112 and the second operating portion 101 .

[0104] Reference Attachment Figure 8When both the water storage unit 20 and the water heating unit 30 are carried by the carrying unit 10, the first pump body 14 can pump water stored in the water storage space 211 of the water storage container 21 into the water heating space 311 of the water heating container 31, where it is subsequently heated by the water heating container 31 to form hot water. When the water heating unit 30 is carried by the carrying unit 10, the second pump body 102 can pump water from the water heating space 311 of the water heating container 31 through the water outlet 103 for drinking by the user. It will be appreciated that the amount of water pumped out of the water heating device through the water outlet 103 can be controlled by controlling the operating time of the second pump body 102. Alternatively, the user can directly pour out the water from the water heating space 311 of the water heating container 31 through the opening of the water heating container 31.

The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles described.
