[0032] The housing 10 has a water inlet 121 and a water outlet 131, the heating tube 20 is arranged in the housing 10, the heating tube 20 has an inner cavity communicating with the water inlet 121 and the water outlet 131, the heating tube 20 is configured to heat the fluid in the inner cavity, the flow guide 30 is arranged in the inner cavity, and a fluid channel is provided between the flow guide 30 and the heating tube 20, the electrical connection component 40 is electrically connected to the heating tube 20, and the electrical connection component 40 is connected to the end of one end of the heating tube 20;

[0033] Specifically, when the quick heating device 100 is working, the water flow can flow through the water inlet, the inner cavity and the water outlet 131 in sequence. A guide member 30 is provided in the inner cavity. A fluid channel is constructed between the guide member 30 and the heating tube 20. The water flow can flow through the fluid channel. Through the guiding effect of the guide member 30, the water flow can flow stably through the quick heating device 100, reducing the noise generated by the water flow in the quick heating device 100, and making it easier for the heating tube 20 to evenly heat the water flow, thereby achieving the purpose of precise temperature control.

[0034] In addition, the electrical connection component 40 is arranged at the end of one end of the heating tube 20, which can facilitate the assembly of the quick heating device 100 in the water dispenser. It can be understood that when the quick heating device 100 is installed, the quick heating device 100 can be connected to the water system in the water dispenser through the water inlet 121 and the water outlet 131 of the outer shell 10, and the electrical connection component 40 is arranged at the end of one end of the heating tube 20, that is, the electrical connection component 40 is arranged close to the water inlet 121 of the outer shell 10. During assembly, the electrical connection component 40 can be conveniently electrically connected to the wiring harness to realize the heating function of the heating tube 20.

[0035] In addition, it can be understood that the heating tube 20 and the guide member 30 are arranged in the shell 10, and the shell 10 is used to achieve a protective effect to prevent the external environment from affecting the normal operation of the heating tube 20, the guide member 30, etc.

[0036] The housing 10 is provided with a temperature monitoring component 90. It is understandable that the temperature monitoring component 90 can monitor the temperature of the water inlet 121 and / or the water outlet 131 to ensure that the water inlet temperature and the water outlet temperature of the quick heating device 100 are within a preset range, thereby achieving more precise temperature control.

[0038] like Figures 2 to 4 In some embodiments of the present invention, the heating tube 20 includes a first tube body portion 21 and a heating portion 22, the inner cavity is arranged in the first tube body portion 21, and the heating portion 22 is laid on the peripheral wall of the first tube body portion 21; in this way, the heating portion 22 can uniformly heat the peripheral wall of the first tube body portion 21, so that the first tube body portion 21 can evenly transfer heat to the water flow, thereby improving the uniformity of heating the water flow.

[0039] In addition, in some examples, the heating portion 22 is laid on the outer peripheral wall of the first tube body portion 21, and a flow guide 30 is provided in the first tube body portion 21. A fluid channel is constructed between the flow guide 30 and the inner peripheral wall of the first tube body portion 21. Water flows along the fluid channel and receives heat from the heating portion 22, thereby achieving uniform heating of the water flow and reducing the occupancy of the inner cavity space by the heating portion 22, thereby facilitating the assembly of the flow guide 30.

[0040] like Figure 2 and Figure 3 In some embodiments of the present invention, the heating portion 22 includes a plurality of heating branches 221, which are spaced apart along the circumference of the first tube body portion 21 and extend along the axial direction of the first tube body portion 21. The plurality of heating branches 221 are connected end to end and extend in a circuitous manner. In this way, the heating portion 22 can evenly cover the peripheral wall of the first tube body portion 21, thereby improving the uniformity of heating of the water flow by the heating tube 20 and realizing precise temperature control of the water flow.

[0041] Exemplarily, the heating portion 22 includes a first heating branch 221 and a second heating branch 221, both of which extend along the axis of the first tube body portion 21 and have two opposite ends respectively, one end of the first heating branch 221 is a free end, and the other end of the first heating branch 221 is connected to the other end of the second heating branch 221, and one end of the second heating branch 221 is a free end. In this way, the first heating branch 221 and the second heating branch 221 can be connected end to end and extend in a circuitous manner, so that the heating portion 22 is evenly arranged on the peripheral wall of the first tube body portion 21, thereby being able to evenly heat the water flowing through the first tube body portion 21.

[0042] like Figure 2 and Figure 3 In some embodiments of the present invention, the head end of the heating part 22 is configured as a first terminal 222, the tail end of the heating part 22 is configured as a second terminal 223, and the first terminal 222 and the second terminal 223 are arranged at the same end of the first tube body part 21; in this way, the heating part 22 can be easily connected to the electrical connection component 40, thereby improving assembly efficiency.

[0043] In combination with the foregoing, one end of the first heating branch 221 is set as the head end of the heating part 22 and is configured as the first terminal 222, and one end of the second heating branch 221 is set as the tail end of the heating part 22 and is configured as the second terminal 223; the first heating branch 221 and the second heating branch 221 are connected head to tail to form a circuitously extended heating part 22, and the head end and the tail end of the heating part 22 are arranged in the same section of the first tube body part 21, so as to facilitate the electrical connection of the heating part 22 with the electrical connection component 40, thereby improving the assembly efficiency of the quick heating device 100.

[0044] like Figure 2 and Figure 3 In some embodiments of the present invention, the heating tube 20 also includes an insulating portion 23, which is laid on the peripheral wall of the first tube body portion 21 and separates adjacent heating branches 221; in this way, conduction and leakage between the heating branches 221 are avoided, thereby improving the safety of the rapid heating device 100.

[0045] Exemplarily, the first heating branch 221 and the second heating branch 221 are arranged adjacent to each other and at intervals, so as to avoid the first heating branch 221 and the second heating branch 221 being too close to each other and causing local concentration of heat, and to allow the first heating branch 221 and the second heating branch 221 to be separated by a predetermined safety distance, and an insulating portion 23 may be provided in the gap between the first heating branch 221 and the second heating branch 221, so as to avoid leakage of electricity when the first heating branch 221 and the second heating branch 221 are powered on for heating, thereby preventing the normal operation of the quick heating device 100 from being affected, and to improve the safety of the quick heating device 100.

[0046] like Figure 2 and Figure 3 In some embodiments of the present invention, the insulating portion 23 includes a plurality of insulating branches 231, which are distributed at intervals along the circumference of the first tube body portion 21 and extend axially or radially along the first tube body portion 21. An insulating branch 231 is provided between each two adjacent heating branches 221; in this way, the insulating portion 23 can evenly cover the peripheral wall of the first tube body portion 21, thereby improving the safety of the rapid heating device 100.

[0047] It can be understood that, taking the axial extension of the insulating branch 231 along the first tube body 21 as an example: two adjacent heating branches 221 among the multiple heating branches 221 are arranged at intervals to avoid local concentration of heat, which affects the normal operation of the multiple heating branches 221, and can separate the multiple heating branches 221 by a predetermined safety distance to avoid safety hazards caused by conductive contact; in addition, an insulating branch 231 is provided between each two adjacent heating branches 221, and the two adjacent heating branches 221 are separated by the insulating branch 231 to avoid leakage when the heating branches 221 are conducting. In addition, the insulating branch 231 and the heating branch 221 both extend along the axial direction of the first tube body 21, so that the insulating branch 231 can separate the adjacent heating branches 221 and improve the insulation effect.

[0048] In addition, taking the radial extension of the insulating branch 231 along the first tube body 21 as an example: the insulating part 23 includes a plurality of insulating branches 231, which are spaced apart along the circumference of the first tube body 21 and extend along the radial direction of the first tube body 21, and an insulating branch 231 is provided between each two adjacent heating branches 221; in this way, the insulating branch 231 can have a certain thickness, so that the first tube body 21 and the heating part 22 can be separated from the protective shell 11 or the external structure by a predetermined distance, thereby improving the safety of the rapid heating device 100 and avoiding the occurrence of leakage hazards. The insulating branch 231 is used to separate the two adjacent heating branches 221 by a predetermined safety distance to avoid safety hazards.

[0049] like Figure 2 and Figure 3 In some embodiments of the present invention, the heating portion 22 has a first terminal 222, a second terminal 223 and a ground terminal 224, the first terminal 222, the second terminal 223 and the ground terminal 224 are arranged at the same end of the heating tube 20, and the electrical connection component 40 includes a first terminal 41, a second terminal 42 and a third terminal 43, the first terminal 41 is connected to the first terminal 222, the second terminal 42 is connected to the second terminal 223, and the third terminal 43 is connected to the ground terminal 224; in this way, the electrical connection component 40 can be easily assembled with the heating tube 20, thereby improving the assembly efficiency.

[0050] Exemplarily, the first terminal 222 of the heating part 22 is provided with a positive terminal, the second terminal 223 of the heating part 22 is set as a negative terminal, the first terminal 41 of the electrical connection component 40 is set as a positive terminal, and the second terminal 42 of the electrical connection component 40 is set as a negative terminal. The positive terminal of the heating part 22 is electrically connected to the external wiring harness through the positive terminal, the negative terminal of the heating part 22 is electrically connected to the external wiring harness through the negative terminal, and the ground terminal 224 of the heating part 22 is connected to the external wiring harness through the third terminal 43. In this way, the heating part 22 can be connected to a power supply to heat the water flow, and the stability of the electrical connection can be improved through the electrical connection component 40, thereby improving the operating stability of the rapid heating device 100.

[0051] The first terminal 222, the second terminal 223 and the ground terminal 224 of the heating part 22 are all located at the same end of the heating tube 20, which facilitates the assembly connection between the heating part 22 and the electrical connection component 40 and improves the assembly efficiency. In addition, the connection between the ground terminal 224 and the third terminal 43 can ground the heating part 22 to avoid damage to the quick heating device 100 when the heating part 22 leaks electricity.

[0052] like Figures 2 to 4 In some embodiments of the present invention, the heating portion 22 is configured as a diaphragm heating structure. Thus, the heating portion 22 can be evenly laid on the peripheral wall of the first tube body portion 21 through the diaphragm heating structure, so that the heating portion 22 can evenly heat the water flow in the first tube body portion 21, thereby making the temperature of the water output from the water dispenser uniform and improving the user experience.

[0053] like Figures 1 to 4 In some other embodiments of the present invention, the quick heating device 100 further includes a grounding portion 24, which is connected to the first tube body portion 21. With this arrangement, the first tube body portion 21 can be grounded through the grounding portion 24, thereby preventing the first tube body portion 21 from being damaged when the quick heating device 100 leaks electricity.

[0054] like Figures 1 to 3 In some embodiments of the present invention, an avoidance gap 14 is provided at the end of the shell 10, and the electrical connection component 40 passes through the avoidance gap 14 and is electrically connected to the heating tube 20; in this way, the space occupied by the quick heating device 100 can be reduced and the space utilization rate of the water dispenser can be improved.

[0055] Exemplarily, the end of the housing 10 is provided with an avoidance notch 14, and the outer surface of the end of the housing 10 is provided with a first fixing seat, a second fixing seat and a third fixing seat, the first wiring portion 41 can be inserted into the avoidance notch 14, one end of the first wiring portion 41 can be connected to the first wiring terminal 222 of the heating portion 22, and the other end can be fixed on the first fixing seat, and the external wiring harness can be connected to the first fixing seat to be electrically connected to the first wiring terminal 222; the second wiring portion 42 can be inserted into the avoidance notch 14, one end of the second wiring portion 42 can be connected to the second wiring terminal 223 of the heating portion 22, and the other end can be fixed on On the second fixing seat, the external wiring harness can be connected to the second fixing seat to be electrically connected to the second wiring part 42; the third wiring part 43 can be inserted into the avoidance gap 14, one end of the third wiring part 43 can be connected to the third wiring terminal of the heating part 22, and the other end can be fixed on the ground fixing seat, and the external wiring harness can be connected to the third fixing seat to be electrically connected to the third wiring part 43; in short, the electrical connection component 40 can be inserted into the avoidance gap 14, so that the structure of the electrical connection component 40 is more concentrated on the quick heating device 100, thereby improving the integration, reducing the volume of the quick heating device 100, and reducing space occupancy.

[0056] like Figure 4 and Figure 5 In some embodiments of the present invention, the quick heating device 100 further includes a water inlet diverter 70 and a water outlet confluence 80, and the water inlet diverter 70 and the water outlet confluence 80 are respectively arranged at opposite ends of the heating tube 20; specifically, when the water flows through the heating tube 20, the water flow may first be subjected to the diversion effect of the water inlet diverter 70, so that the water flow may be evenly distributed in the fluid channel, and then flow to the water outlet confluence 80 under the guiding effect of the guide member 30, and the water flow is subjected to the reflux effect of the water outlet confluence 80, and is discharged from the water outlet 131 in a concentrated manner. In this process, the heating tube 20 may be convenient for evenly heating the water flow, thereby improving the heat uniformity of the water flow.

[0057] More specifically, at least one of the water inlet diversion portion 70 and the water outlet confluence portion 80 includes: a flow balancing portion, which covers the end of the fluid channel and is provided with a plurality of flow balancing holes, and the plurality of flow balancing holes are distributed along the circumference of the heating tube 20; in this way, the plurality of flow balancing holes can realize the diversion and confluence of water flow, so as to facilitate the heating tube 20 to uniformly heat the water flow.

[0058] According to the foregoing, in some examples, the water inlet diversion section 70 includes a first flow balancing section 71, the first flow balancing section 71 includes a plurality of first flow balancing holes 711, and the water outlet confluence section 80 includes a second flow balancing section 81, the second flow balancing section 81 includes a plurality of second flow balancing holes 811; when the water flows through the heating tube 20, the water can flow through the plurality of first flow balancing holes 711, and the plurality of first flow balancing holes 711 distribute the water into the fluid channel, so that the water flows evenly in the fluid channel, and then the water can flow through the plurality of second flow balancing holes 811, and the plurality of second flow balancing holes 811 concentrate the water and discharge it from the water outlet 131.

[0059] like Figure 4 and Figure 5 In some embodiments of the present invention, the flow guide 30 includes a second tube body portion 31 and a flow guide portion 32. The second tube body portion 31 is arranged in the heating tube 20 and extends in the same direction as the heating tube 20. The flow guide portion 32 is arranged on the outer peripheral surface of the second tube body portion 31 and is located between the second tube body portion 31 and the heating tube 20. The flow guide portion 32 is arranged to extend in an axial spiral along the second tube body portion 31. In this way, the flow guide 30 can guide the water flow to flow evenly in the heating tube 20, which facilitates the heating tube 20 to evenly heat the water flow and achieve precise temperature control.

[0060] It can be understood that the guide portion 32 extends in an axial spiral along the second tube body portion 31 to form a spiral guide portion 32. When water flows through the fluid channel, it can flow in a spiral along the guide portion 32, so that the water flows evenly in the fluid channel and the flow time of the water in the fluid channel can be extended. This makes it easier for the heating tube 20 to evenly heat the water flow and achieve precise temperature control of the water flow.

[0061] Preferably, the guide portion 32 is configured to be sheet-shaped, that is, spirally extending along the second tube portion 31 to increase the guide area of ​​the guide portion 32 , so that the water flows evenly along the fluid channel, making it easier for the heating tube 20 to evenly heat the water.

[0062] In addition, at least one of the water inlet diversion portion 70 and the water outlet confluence portion 80 also includes a plug, which seals the end of the second tube body portion 31, the inner periphery of the flow equalizing portion is connected to the plug, and a plurality of flow equalizing holes are arranged on the outer periphery of the flow equalizing portion; in this way, the water inlet diversion portion 70 and the water outlet confluence portion 80 can be installed on the second tube body portion 31, and water flow can be prevented from entering the second tube body portion 31.

[0063] According to the foregoing, in some examples, the water inlet diversion portion 70 also includes a first plug 72, which blocks one end of the second tube body portion 31 so that the water inlet diversion portion 70 can be installed on the second tube body, and the water inlet diversion portion 70 can block one end of the second tube body portion 31 to prevent water from entering the second tube body portion 31 and affecting the uniform flow and heating of the water; similarly, the water outlet confluence portion 80 also includes a second plug 82, which blocks the other end of the second tube body portion 31 so that the water outlet confluence portion 80 can be installed on the second tube body, and the water outlet confluence portion 80 can block the other end of the second tube body portion 31 to prevent water from entering the second tube body portion 31 and affecting the uniform flow and heating of the water.

[0064] like Figures 1 to 4 In some embodiments of the present invention, the housing 10 includes a water inlet connector 12 and a water outlet connector 13, the water inlet connector 12 and the water outlet connector 13 are respectively connected to the two ends of the heating tube 20, and at least one of the water inlet connector 12 and the water outlet connector 13 is provided with a temperature monitoring component 90; it can be understood that the quick heating device 100 can be used in a water dispenser, and the quick heating device 100 can be quickly connected to the water system in the water dispenser through the water inlet connector 12 and the water outlet connector 13, thereby improving the assembly efficiency. In some specific examples, the water inlet connector 12 is provided with a water inlet temperature monitoring component 91, which can monitor the water flow temperature at the water inlet 121, and the water outlet connector 13 is provided with a water outlet temperature monitoring component 92, which can monitor the water flow temperature at the water outlet 131, so that precise temperature control of water flow heating can be achieved.

[0065] In addition, the water inlet joint 12 has the aforementioned water inlet 121 , and the water outlet joint 13 has the aforementioned water outlet 131 .

[0066] like Figures 1 to 4 In some embodiments of the present invention, the quick heating device 100 further includes a temperature control switch 50 and a temperature limiter 60, which are arranged in the housing 10 and in contact with the heating tube 20; in this way, the safe operation of the quick heating device 100 can be ensured to avoid damage caused by excessive temperature.

[0067] Exemplarily, the quick heating device 100 is arranged in the up and down direction, the water inlet 121 of the quick heating device 100 is at the bottom, the water outlet 131 of the quick heating device 100 is at the top, and the temperature control switch 50 is arranged above the temperature limiter 60; when the heating tube 20 is overheated, the heat near the temperature control switch 50 is greater than the heat near the limiter, and the temperature control switch 50 is triggered first to control the quick heating device 100 to stop running; if the temperature control switch 50 fails, it is triggered by the temperature limiter 60 to control the quick heating device 100 to stop running. The temperature limiter 60 is a redundant design, and is combined with the temperature control switch 50 to achieve a double insurance effect, which can further improve the safety of the quick heating device 100. In addition, the temperature control switch 50 can be automatically restored. For example, after the temperature control switch 50 is triggered, if the temperature of the quick heating device 100 drops, the temperature control switch 50 can be restored to the state before the triggering, and the temperature limiter 60 needs to be manually restored. For example, after the temperature limiter 60 is triggered, if the temperature of the quick heating device 100 drops, the temperature limiter 60 cannot be restored to the state before the triggering. The user needs to disassemble the quick heating device 100 and manually restore the temperature limiter 60 to the state before the triggering. In this way, the safety of the quick heating device 100 can be further improved, and the risk of failure of the temperature limiter 60 can be avoided.

[0068] like Figures 1 to 4 In some embodiments of the present invention, the housing 10 further includes a protective shell 11, which is disposed on the outside of the heating tube 20, and the temperature control switch 50 and the temperature limiter 60 are disposed on the protective shell 11 and in contact with the peripheral wall of the heating tube 20; specifically, the heating tube 20 is disposed in the protective shell 11, and the two ends of the protective shell 11 are respectively connected to the water inlet joint 12 and the water outlet joint 13. The protective shell 11 can separate the heating tube 20 from the external environment, thereby preventing the heating tube 20 from damaging other structural components in the water dispenser and preventing the external environment from affecting the normal operation of the heating tube 20.

[0069] In addition, the protective shell 11 has a first mounting hole and a second mounting hole. The temperature control switch 50 is inserted into the first mounting hole to contact the peripheral wall of the heating tube 20 and is connected to the periphery of the first mounting hole through fasteners; the temperature limiter 60 is inserted into the second mounting hole to contact the peripheral wall of the heating tube 20 and is connected to the periphery of the second mounting hole through fasteners; in this way, the temperature control switch 50 and the limiter can be easily disassembled and replaced, thereby improving the convenience of disassembly and assembly.

[0070] like Figures 1 to 4In some embodiments of the present invention, in combination with the foregoing, the water inlet 121 is provided at the water inlet joint 12, and the water inlet 121 is arranged so that the axis thereof extends along the axis of the heating tube 20. In this way, the water inlet joint 12 has a simple structure and is easy to manufacture, and when the quick heating device 100 is arranged up and down, the space occupied by the quick heating device 100 in the water dispenser can be reduced, making the structure of the water dispenser thinner; similarly, the water outlet 131 is provided at the water outlet joint 13, and the water outlet 131 is arranged so that the axis thereof extends along the axis of the heating tube 20. In this way, the water outlet joint 13 has a simple structure and is easy to manufacture, and when the quick heating device 100 is arranged up and down, the space occupied by the quick heating device 100 in the water dispenser can be reduced.

[0071] like Figures 1 to 5 According to the water dispenser of the embodiment of the present invention, the water dispenser includes the quick heating device 100 in the above embodiment. By applying the above quick heating device 100, the precise temperature control of the water flow can be achieved and the noise of the water dispenser can be reduced.

[0072] Specifically, the quick heating device 100 can be used in a water dispenser, and since the quick heating device 100 in the embodiment of the present invention has a good temperature control effect, it can be used in a water dispenser without a water tank. It can be understood that the quick heating device 100 can make the water flow evenly through it and heat the water evenly, and has a precise temperature control effect. Therefore, there is no need to set a water tank in the water dispenser for buffering. In this way, the volume of the water dispenser is reduced and the integration of the water dispenser is improved.

[0073] Working principle of the quick heating device 100:

[0074] Water flows into the quick heating device 100 from the water inlet 121, and is divided into multiple parts under the diversion effect of the water inlet diversion part 70. The water flows evenly in the fluid channel under the diversion effect of the guide part 32, and the water flows converge and discharge from the quick heating device 100 from the water outlet 131 under the diversion effect of the water outlet confluence part 80 to reduce the noise generated by the impact of the water flow. In this process, the heating part 22 is laid on the first pipe body part 21 to evenly heat the water flow in the fluid channel. In this way, the uniformity of the heating of the water flow can be improved, and the precise temperature control of the water flow can be achieved.

[0075] Furthermore, a plurality of heating branches 221 are distributed at intervals in the circumferential direction of the first tube body 21, and extend along the axis of the first tube body 21, and are connected end to end in a circuitous extension to cover the peripheral wall of the first tube body 21, thereby improving the uniformity of heating the water flow. An insulating branch 231 is provided between two adjacent heating branches 221, and the insulating branch 231 separates the two adjacent heating branches 221, thereby avoiding leakage hazards between the two adjacent heating branches 221.

[0076] Furthermore, the first terminal 222, the second terminal 223 and the grounding terminal 224 of the heating part 22 are arranged at the same end of the heating tube 20, and the first terminal 41, the second terminal 42 and the third terminal 43 of the electrical connection component 40 are also arranged at the same end of the outer shell 10, which facilitates the connection between the electrical connection component 40 and the heating tube 20 and improves assembly efficiency.

[0077] In some specific examples, when the instant heating component (i.e., the quick heating device 100) is installed vertically, water flows from the water inlet end cover (i.e., the water inlet joint 12) into the instant heating pipe (i.e., the heating pipe 20), and under the guiding action of the metal guide column component (i.e., the guide member 30), the water flows through the side hole of the current limiting sealing ring (i.e., the flow equalizing hole) into the instant heating pipe, and rises evenly along the metal guide component in a spiral, so that the water is heated evenly and the water flow is smooth, and bubbles generated by the water flow during the heating process are reduced, and the heating noise and water flow fluctuations are reduced. Considering the installation of the guide column component and the realization of the guide function, there is a gap of 0.1mm-0.5mm between the outer diameter of the guide column component and the inner diameter of the instant heating pipe, wherein the gap can be 0.1mm, 0.2mm, 0,3mm, 0.4mm, 0.5mm, etc. Note: For water hygiene, the material of this guide column component is 304 stainless steel.
