[0031] The following is combined with Figure 1 and Figure 2 This application describes a liquid heating device.

[0032] According to an embodiment of this application, a liquid heating device is provided. Please refer to... Figure 1 and Figure 2 The liquid heating device includes a base 100 and a water tank assembly 200. The base 100 includes a water pipe 110, an instant heating component 120, and a water outlet component 130. The water pipe 110 is connected to the instant heating component 120, and the instant heating component 120 is connected to the water outlet component 130. The water tank assembly 200 includes a heating plate assembly 210 and a water tank inner tank 220. The heating plate assembly 210 is installed in the water tank inner tank 220 and is suitable for heating the water tank inner tank 220. The bottom of the water tank inner tank 220 is provided with a water drain port 221. The water tank assembly 200 is detachably connected to the base 100. When the water tank assembly 200 is connected to the base 100, the water pipe 110 is connected to the water drain port 221.

[0033] According to the liquid heating device of this application embodiment, the water tank assembly 200 is entirely detachable, greatly improving user convenience. Users do not need to move the entire liquid heating device; they can easily disassemble the water tank assembly 200 to conveniently fill, clean, or replace the inner tank liner 220. The water pipe 110 is responsible for transporting the water in the inner tank liner 220 to the instant heating component 120, which then rapidly heats the water to the specified temperature according to user needs, finally allowing it to flow out through the water outlet component 130. The base 100 of this application avoids the drawback of traditional electric water bottles requiring the water to cool naturally, providing a more immediate and personalized drinking experience.

[0034] It is understood that the base 100 refers to the part of the liquid heating device responsible for the water dispensing function. The base 100 includes components such as water pipes 110, instant heating components 120, and water dispensing components 130. The water pipes 110, instant heating components 120, and water dispensing components 130 can store a certain amount of water. The instant heating components 120 are used to quickly heat the water to a specified temperature. The water pipes 110 are used to connect the instant heating components 120 to the water outlet 221 of the water tank inner liner 220. The water dispensing components 130 can be a valve body or a faucet, etc., used to control the water dispensing.

[0035] The water tank assembly 200 is used to boil liquids. The water tank assembly 200 includes components such as a heating element assembly 210 and a water tank inner tank 220. The heating element assembly 210 is a heating element located at the bottom or other position of the water tank inner tank 220. The heating element assembly 210 generates heat through an electric current, heating the water in the water tank inner tank 220 to a boiling state. The water tank inner tank 220 is used to store water.

[0036] According to one embodiment of this application, the liquid heating device includes a first coupling assembly 300, which includes a first coupling member 310 and a second coupling member 320. The first coupling member 310 is disposed at a water outlet 221, and the second coupling member 320 is disposed at the inlet of a water pipe 110. When the water tank assembly 200 is connected to the base 100, the first coupling member 310 is electrically connected to the second coupling member 320, and the first coupling member 310 and the second coupling member 320 communicate between the water outlet 221 and the inlet.

[0037] It is understood that the first coupling assembly 300 includes a first coupling element 310 and a second coupling element 320, respectively disposed at the water outlet 221 and the inlet of the water pipe 110. When the water tank assembly 200 is connected to the base 100, the first coupling element 310 and the second coupling element 320 can automatically align and connect tightly without manual operation by the user or the assistance of additional tools. When the first coupling element 310 and the second coupling element 320 are tightly connected, water flow between the water outlet 221 and the inlet of the water pipe 110 can be achieved.

[0038] In addition, the first coupling component 300 not only achieves physical connection but also electrical connection. During the connection process, an electrical connection is established between the first coupling component 310 and the second coupling component 320, which ensures that the water tank assembly 200 can normally receive electrical signals from the controller 170 located on the base 100 to achieve heating and power off.

[0039] In one embodiment, the first coupling component 300 is a 5-pin coupler.

[0040] According to one embodiment of this application, the base 100 includes a one-way valve 140 disposed between the instant heating component 120 and the water outlet component 130. The one-way valve 140 only allows water to flow from the instant heating component 120 to the water outlet component 130, effectively preventing water from flowing back from the water outlet component 130 into the instant heating component 120 or the water tank assembly 200. After the water tank is removed, even if there is a height difference, the water in the base 100 will not flow back into the instant heating component 120 or the water tank due to gravity, ensuring the normal operation of the equipment and the user's drinking water safety.

[0041] In addition, the one-way valve 140 can ensure that the instant heating component 120 is full of water, so users do not need to worry about water backflow or dry burning caused by improper operation or equipment failure, and can use the equipment with more peace of mind.

[0042] In one embodiment, a one-way valve 140 is located between the water pipe 110 and the instant heating component 120. The one-way valve 140 only allows water to flow from the water pipe 110 to the instant heating component 120, effectively preventing backflow of water from the instant heating component 120. After the water tank is removed, even with a height difference, the water in the instant heating component 120 will not flow back due to gravity, ensuring the normal operation of the equipment and the user's drinking water safety. Users do not need to worry about water backflow or dry burning caused by improper operation or equipment malfunction, and can use the equipment with greater peace of mind.

[0043] According to one embodiment of this application, the base 100 includes a pump body 150, which is disposed in a water path formed between the water pipe 110, the instant heating component 120, and the water outlet component 130. The pump body 150 can regulate the water pressure in the water path to keep it within a suitable range, thereby ensuring the heating efficiency and the stability of the outlet water temperature, and significantly improving the water outlet efficiency of the liquid heating device.

[0044] In one embodiment, the valve body is a diaphragm pump.

[0045] According to one embodiment of this application, the base 100 includes an integrally connected base 101 and a water outlet 102. The water tank assembly 200 is detachably connected to the base 101, the water outlet 102 is connected to the base 101, the instant heating assembly 120 and the water outlet component 130 are disposed on the water outlet 102, and a portion of the water pipe 110 is disposed on the water outlet 102 and a portion of the water pipe 110 is disposed on the base 101.

[0046] It is understood that the water tank assembly 200 is detachably connected to the base 101, which provides stable support for the water tank assembly 200. The water outlet seat 102 can be fixedly connected to the base 101, or it can be integrally formed with the base 101, or it can be fixedly connected to the base 101 by other fasteners. No specific limitation is made here.

[0047] The instant heating element 120, the water outlet component 130, and part of the water pipes 110 are all located on the water outlet base 102. This layout makes the water path more compact and efficient. Water can maintain a high flow rate and stability when flowing through these components, thereby improving water output efficiency.

[0048] According to one embodiment of this application, the liquid heating device includes a fan 160, which is disposed on the water outlet seat 102. The air outlet of the fan 160 (not shown in the figure) faces the water tank assembly 200. The water tank assembly 200 includes a water tank shell (not shown in the figure), and a water tank inner liner 220 is installed inside the water tank shell. The water tank shell is provided with an air inlet (not shown in the figure), which faces the water tank inner liner 220. The airflow generated by the fan 160 passes through the air outlet and the air inlet in sequence and blows onto the water tank inner liner 220.

[0049] Understandably, the fan 160 serves a heat dissipation function. During the heating process, the inner tank 220 generates a certain amount of heat. By blowing air into the inner tank 220, the fan 160 can accelerate heat dissipation, lower the temperature of the liquid inside the tank 220, and quickly reduce the temperature of the boiling water.

[0050] According to one embodiment of this application, the base 100 includes a controller 170, which is electrically connected to the instant heating assembly 120. When the water tank assembly 200 is connected to the base 100, the controller 170 is electrically connected to the heating plate assembly 210.

[0051] Understandably, the controller 170 is electrically connected not only to the instant heating component 120, but also to the heating plate component 210 when the water tank component 200 is connected to the base 100. This enables unified control of both the instant heating component 120 and the heating plate component 210, simplifying the circuit structure, reducing costs, and improving control accuracy and response speed. Users can conveniently adjust the operating status of the instant heating component 120 and the heating plate component 210 through the controller 170 to meet different heating needs.

[0052] If an abnormality (such as overheating or overcurrent) is detected during the operation of the device, the controller 170 will immediately cut off the power supply to protect the instant heating component 120, the heating plate component 210, and the safety of the entire device.

[0053] According to one embodiment of this application, the water tank assembly 200 includes a water detection assembly 230, which includes a water detection pipe 231, a float 232, and a reed switch 233. The first end of the water detection pipe 231 is connected to the atmosphere, and the second end of the water detection pipe 231 is connected to the inner tank liner 220 of the water tank. The water detection pipe 231 and the inner tank liner 220 form a communicating vessel. The float 232 is disposed inside the water detection pipe 231, and the reed switch 233 is installed inside the water tank assembly 200. The reed switch 233 is used to detect the position of the float 232 to determine the water level of the inner tank liner 200.

[0054] The water level detection assembly 230 is a device used to detect the water level in the inner tank 220. The assembly includes components such as a water level detection pipe 231, a float 232, and a reed switch 233. Accurate water level detection and monitoring are achieved by the up-and-down movement of the float 232 within the water level detection pipe 231. The water level detection pipe 231 and the inner tank 220 form a communication device for transmitting water level information.

[0055] A float 232 is located inside the water detection pipe 231 and moves up and down with the rise and fall of the water level to trigger a change in the switching state of the reed switch 233. The reed switch 233 is a magnetic switch and is located at the lowest water level position in the inner tank liner 220. When the float 232 moves to the position of the reed switch 233, it triggers a change in its switching state, thereby sending a water level signal to the controller 170.

[0056] Understandably, the water detection component 230, through the combination of the water detection pipe 231, the float 232, and the reed switch 233, achieves accurate detection and monitoring of the water level in the inner tank 220. The water detection pipe 231 forms a communication device with the inner tank 220, ensuring that the float 232 can move up and down with the rise and fall of the water level. The combined use of the float 232 and the reed switch 233 enables the device to monitor changes in the water level in the inner tank 220 in real time.

[0057] When the water level in the inner tank 220 is too low, the float 232 will descend and trigger the reed switch 233 to change its state, sending a water shortage signal to the controller 170. Upon receiving the signal, the controller 170 can immediately cut off the power to the heating element to prevent dry burning due to water shortage and protect the device's safety.

[0058] The water detection assembly 230 has a simple structure and is easy to maintain. When cleaning or replacement of parts is required, users can easily disassemble and replace the relevant parts without disassembling the entire device.

[0059] In one embodiment, the highest position of the water detection pipe 231 corresponds to the highest water level setting of the inner tank liner 220, and the lowest position of the water detection pipe 231 corresponds to the lowest water level setting of the inner tank liner 220; the float 232 is located inside the water detection pipe 231, and the reed switch 233 is located at the same height as the lowest water level in the inner tank liner 220.

[0060] In one embodiment, the float 232 is a magnetic float, and the water detection pipe 231 is provided with a minimum predetermined water level position, which corresponds to the lowest water level setting of the inner tank liner 220. The reed switch 233 is set at the minimum predetermined water level position. When the float 232 is at the minimum predetermined water level position, the magnetic field of the float 232 and the reed switch 233 interact magnetically, triggering the reed switch 233 to output a water level warning signal.

[0061] It is understandable that the magnetic float can have an embedded magnet, or the float 232 itself can be a magnetic component. The float moves up and down with the water level in the inner tank 220. When the water level in the inner tank 220 is higher than the minimum preset water level, the magnetic float 232 is located above the water detection pipe 231, away from the reed switch 233. At this time, the reed switch 233 is in the normally open state and does not output any warning signal. As the water level in the inner tank 220 gradually decreases, the magnetic float 232 also decreases. When the water level approaches the minimum preset water level, the magnetic float 232 gradually approaches the reed switch 233. When the water level reaches the minimum preset water level, the magnetic field of the magnetic float 232 interacts with the reed switch 233, triggering the reed switch 233 to close or open. At this time, the reed switch 233 outputs a water level warning signal, reminding the user that the water level in the inner tank 220 has reached the minimum preset water level and that water needs to be added in time.

[0062] In one embodiment, a second coupling component 400 is included, which includes a third coupling member 410 and a fourth coupling member 420. The third coupling member 410 is disposed on the water tank assembly 200 and connected to the reed switch 233. The fourth coupling member 420 is disposed on the base 100 and is detachably connected to the fourth coupling member 420.

[0063] The third coupling element 410 is mounted on the water tank assembly 200 and connected to the reed switch 233. Its main function is to transmit the signal from the reed switch 233 to the fourth coupling element 420. The fourth coupling element 420 is mounted on the base 100 and is used to receive the signal from the third coupling element 410. The third coupling element 410 and the fourth coupling element 420 are detachably connected, which facilitates the separation and maintenance of the water tank assembly 200 from the base 100.

[0064] In one embodiment, the fourth coupling element 420 is electrically connected to the controller. The water level warning signal output by the reed switch 233 can be transmitted to the controller through the third coupling element 410 and the fourth coupling element 420. The controller can control the heating plate assembly to turn off, control the indicator light to turn on, or control the sound to remind the user that the water level inside the inner tank 220 is at its lowest level.

[0065] In one embodiment, the second coupling component 400 is a 2-pin coupler.

[0066] In one embodiment, the float 232 is a magnetic float 232.

[0067] In one embodiment, the water detection pipe 231 of the water detection component 230 is connected to the bottom of the inner tank 220, and there is a certain distance between the water detection pipe 231 and the connecting hole and the water discharge port 221 of the inner tank 220, so as to ensure that the water level in the water detection pipe 231 will not be affected during the diaphragm pump pumping process.

[0068] In one embodiment, the water tank assembly 200 includes a thermostat assembly, which includes components such as an NTC temperature sensor, a trip unit, and a fuse.

[0069] According to one embodiment of this application, the water tank assembly 200 includes a water tank cover 240, which covers the inner tank liner 220.

[0070] Understandably, the water tank lid 240 fits tightly over the inner tank liner 220, forming an effective sealing barrier. This design effectively prevents water evaporation, reduces water waste, and also prevents external impurities and microorganisms from entering the inner tank liner 220, ensuring the cleanliness and hygiene of the water.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should be covered within the scope of the claims of this application.
