It should be noted that the "first", "second", etc. concepts mentioned in the utility model are only used to distinguish different devices, modules or units, and are not intended to limit the functions performed by these devices, modules or units.

[0029] It should be noted that the modification of "one" or "multiple" mentioned in the utility model is illustrative and not limiting, and those skilled in the art should understand that unless otherwise explicitly indicated in the context, it should be understood as "one or more".

[0030] As shown in Figure 1 , Figure 2 The utility model embodiment provides a kind of heating device, comprising: water storage container, water container 1, first heating body 2 and second heating body, first water outlet is equipped on water storage container, first water inlet is equipped on water container 1, first water outlet and first water inlet are equipped with water pipeline 3, water in water storage container flows into water container 1 in sequence through first water outlet, water pipeline 3 and first water inlet, first heating body 2 is used to heat the water in water pipeline 3, and second heating body is used to heat the water in water container 1.

[0031] Specifically, the water storage container is used to store water to be heated, and is provided with a first water outlet for discharging water to a subsequent heating process. The water holding container 1 is used to receive preheated water and further heat and keep it warm, and is provided with a first water inlet connected to the first water outlet of the water storage container through the water pipeline 3. The water pipeline 3 connects the first water outlet of the water storage container and the first water inlet of the water holding container 1 to form a water flow channel so that water can flow therein and be heated by the first heating body 2. The first heating body 2 is arranged in or near the water pipeline 3 to quickly preheat the flowing water. The second heating body is arranged in or near the water holding container 1 to further heat the received preheated water until the user required temperature is reached and maintain the water temperature after the heating is completed.

[0032] In this embodiment, when hot water is needed, the water in the water storage container first flows out through the first water outlet and enters the water pipeline 3. At this time, the first heating body 2 heats the water in the water pipeline 3. Since the water quantity in the water pipeline 3 is relatively small and the water is heated during the flow, the preheating temperature can be quickly reached or close to the boiling state. The heating in this stage aims to quickly provide hot water and reduce the user waiting time. The preheated water flows into the water holding container 1 through the first water inlet. In the water holding container 1, the second heating body continues to heat the water until the user required final temperature (such as boiling) is reached. By simultaneously heating the water injected into the water holding container 1 by the first heating body 2 and the second heating body, the heating efficiency is improved. Importantly, when the water in the water holding container 1 reaches the corresponding water level and is heated to the pre-set temperature, the injection of water into the water holding container 1 through the water pipeline 3 is stopped, and the heating of the water in the water pipeline 3 by the first heating body 2 is also stopped. The second heating body can maintain low power operation or intermittent operation to keep the water temperature in the water holding container 1 within the set range. In this way, the water in the water holding container 1 can maintain the hot water state for a long time to meet the user's frequent use or long time keeping requirements. In this embodiment, when water is injected into the water holding container 1, the first heating body 2 and the second heating body simultaneously heat the water injected into the water holding container 1 to provide heating efficiency, shorten the heating time, and achieve the effect of quick heating as soon as the user opens the faucet. After the water injection into the water holding container 1 is completed, the second heating body continuously heats the water in the water holding container 1 to effectively maintain the water temperature, meeting the user's long time keeping or frequent use of hot water requirements. During use, the user adjusts the power and working mode of the heating body according to the needs to adapt to different water use requirements. For example, when hot water is urgently needed, the power of the first heating body 2 can be increased to speed up the preheating process; and when long time keeping is needed, the working mode of the second heating body can be adjusted to maintain the water temperature.

[0033] Optionally, as Figure 1 , Figure 2 , Figure 3As shown, the base 4 is further provided with a second water inlet 41 and a second water outlet 42, the first water inlet is communicated with the second water inlet 41, and the second water outlet 42 is communicated with the first water outlet, and the water passing pipeline 3 and the first heating body 2 are arranged in the base 4, and the water passing pipeline 3 is connected between the second water inlet 41 and the second water outlet 42.

[0034] Specifically, the base 4 serves as a support structure of the entire heating device, stably bearing the water storage container and the water containing container 1, and facilitating user operation and movement. The base 4 can also effectively protect the internal heating elements and waterway system, prolonging the service life. The base 4 is provided with a second water inlet 41 and a second water outlet 42, which are respectively communicated with the first water inlet of the water containing container 1 and the first water outlet of the water storage container, realizing flexible connection of the waterway, so that water can flow smoothly between the water storage container, the water passing pipeline 3 and the water containing container 1. At the same time, it is also convenient for users to clean and maintain the waterway when necessary. The water passing pipeline 3 and the first heating body 2 are arranged in the base 4 and connected between the second water inlet 41 and the second water outlet 42, which not only saves space, but also makes the heating process more concealed and safe. The first heating body 2 preheats the water in the water passing pipeline 3 in the base 4, improving the heating efficiency and avoiding external environmental interference.

[0035] In this optional embodiment, by increasing the base 4 and the related waterway connection, the overall structure of the heating device is more compact and stable, improving the convenience and safety of use. The second water inlet 41 and the second water outlet 42 on the base 4 facilitate users to clean and maintain the waterway, prolonging the service life of the heating device. By arranging the water passing pipeline 3 and the first heating body 2 in the base 4, the space is effectively saved, making the heating device more compact and beautiful, and the hidden heating elements and waterway system avoid direct contact with the external environment, reducing safety hazards and improving the safety of the heating device.

[0036] Optionally, the second heating body is arranged on one side of the base 4 close to the water containing container 1.

[0037] Or, the second heating body is arranged in the water containing container 1.

[0038] Specifically, the second heating body can have two different setting modes: one is set on the side of the base 4 close to the water container 1; the other is directly set in the water container 1. When the second heating body is set on the side of the base 4 close to the water container 1 (such as electric stove, electric ceramic stove, etc.), in this setting mode, the second heating body forms a heat conduction relationship with the water container 1 through the base 4, when the second heating body works, the heat generated by it is transmitted to the water container 1 through the base 4, and then heats the water in the container, which is beneficial to the uniform distribution and transmission of heat, and avoids the problem of local overheating or uneven heating. At the same time, since there is a certain distance between the second heating body and the water container 1 (separated by the base 4), it can reduce the direct impact on the material of the water container 1 to some extent during heating, prolonging the service life of the container. When the second heating body is set in the water container 1 (such as electric kettle mode), in this setting mode, the second heating body is directly immersed in the water in the water container 1, which can respond more quickly to the heating demand by directly contacting with water, because the heat is directly transmitted to the water, reducing the loss in the heat transfer process. In addition, since the second heating body is directly placed in the water, it can also more accurately control the water temperature and achieve more detailed heating adjustment. However, the waterproof and insulation performance of the heating element needs to be paid attention to in this design to ensure the safety of use.

[0039] In this optional embodiment, whether the second heating body is set on the side of the base 4 close to the water container 1 or directly set in the water container 1, it can more efficiently heat the water in the container, reduce the heating time, and improve the heating efficiency. The two setting modes have their own advantages, and the most suitable heating mode can be selected according to different use scenarios and needs. For example, when a large amount of water needs to be heated quickly, the second heating body can be set in the water container 1; while when long-term insulation or heating a small amount of water is needed, the second heating body can be set on the side of the base 4 close to the water container 1. By providing two different setting modes of the second heating body, the heating device is more flexible and practical, and can meet the use needs and preferences of different users.

[0040] Optionally, as shown in Figure 1 the water container 1 includes a kettle, the kettle includes a kettle body 11 and a handle 12, the handle 12 is connected to the side of the kettle body 11, the first water inlet is arranged at the bottom of the kettle body 11, and the handle 12 is provided with a water inlet channel, one end of the water inlet channel close to the base 4 is in communication with the first water inlet, and the other end of the water inlet channel away from the base 4 is in communication with the internal cavity of the kettle body 11.

[0041] Specifically, the water container 1 adopts the form of a kettle, including a kettle body 11, a handle 12 and other components. The handle 12 is connected to the side of the kettle body 11, facilitating the user to hold and move the kettle. The first water inlet is arranged at the bottom of the kettle body 11, and the handle 12 is provided with a water inlet channel. One end of the water inlet channel close to the base 4 is in communication with the first water inlet, and the other end of the water inlet channel away from the base 4 is in communication with the internal cavity of the kettle body 11. When it is necessary to add water to the kettle, the water in the water storage container flows into the water passing pipeline 3 through the first water outlet, and then flows into the handle 12 through the first water inlet. The water flows into the internal cavity of the kettle body 11 through the communication port between the water inlet channel and the internal cavity of the kettle body 11.

[0042] In this optional embodiment, by arranging the water inlet channel in the handle 12, the water in the water storage container can flow into the kettle body 11 from the inside of the top of the handle 12 through the water passing pipeline 3 and the water inlet channel, without worrying about water splashing or dripping, thereby improving the water adding efficiency and making the use of the kettle more humanized. The user can operate more easily and happily during use, and the user experience is enhanced. Since the water adding process is more convenient and less likely to splash, the cleaning work is reduced, and the maintenance cost of the user is reduced.

[0043] Optionally, as shown in Figure 3 the base 4 is provided with a smart seat 43, and the water storage container is connected in the smart seat 43. The second water inlet 41 is arranged on the smart seat 43.

[0044] Specifically, the smart seat 43 is fixed on the base 4 and includes a groove or a buckle structure matched with the shape of the bottom of the water storage container and a sealing device corresponding to the water outlet of the water storage container. The smart seat 43 enables the water storage container to be conveniently installed and removed, while ensuring the sealing of water during flow. The water storage container (such as bottled water) is connected to the smart seat 43 through the structure (such as the bottle mouth) at the bottom thereof. The connection is stable and convenient, so that the user can easily replace or clean the water storage container.

[0045] In this optional embodiment, the arrangement of the smart seat 43 makes the installation and removal of the water storage container very simple and fast, and the user can complete the operation without using any tools, greatly improving the use convenience of the equipment and enabling the user to save time and effort during use.

[0046] Optionally, as shown in Figure 4 the first heating body 2 includes an outer shell 21, and the outer shell 21 is provided with an inner tube 22. The two ends of the inner tube 22 extend out of the outer shell 21 and are respectively provided with a third water inlet 24 and a third water outlet 25. The third water inlet 24 and the third water outlet 25 are in communication with the water passing pipeline 3. The outer shell 21 and the inner tube 22 are provided with a heating assembly 23 therebetween.

[0047] Specifically, the shell 21 serves as an external protective structure for the first heating body 2. The shell 21 is made of high-strength and high-temperature-resistant material, and its shape and size are designed according to actual needs to ensure sufficient strength and stability. The inner wall of the shell 21 is also provided with a heat insulation layer to reduce heat loss and protect the external environment from high temperature. The inner tube 22 is located inside the shell 21 and is the main channel for water flow. The inner tube 22 is made of corrosion-resistant and high-temperature-resistant material to ensure its stability and durability in a long-term high-temperature and high-pressure environment. The two ends of the inner tube 22 extend out of the shell 21 and are respectively provided with a third water inlet 24 and a third water outlet 25. These two openings are connected to the water pipeline 3 through connecting pieces to form a complete water flow path. The heating assembly 23 is arranged in the gap between the shell 21 and the inner tube 22, which can be an electric heating wire, an electric heating tube or other forms of heating elements. The heating assembly 23 generates heat through electric energy or other energy sources and transfers the heat to the water in the inner tube 22 through heat conduction. The design and control method of the heating assembly 23 can be adjusted according to actual needs to achieve precise heating control. The water pipeline 3 is connected to the third water inlet 24 and the third water outlet 25 to form a complete water flow path. The design of the water pipeline 3 can be adjusted according to actual needs to adapt to different water flow speed and pressure requirements. At the same time, the water pipeline 3 can also be provided with filters, flow meters and other accessories to improve the quality of water and heating efficiency.

[0048] In this optional embodiment, when water is poured into the water container 1, the water enters the inner tube 22 from the water pipeline 3 and the third water inlet 24, then flows along the inner tube 22 to the third water outlet 25, and flows into the water container 1 through the water pipeline 3. In this process, the heating assembly 23 starts to work, generates heat and transfers it to the water in the inner tube 22. The water continuously absorbs heat during the flow process, and the temperature gradually rises. When the water flows out of the third water outlet 25, its temperature has risen to a preset value, thereby meeting the heating requirement. Since the heating assembly 23 is directly arranged between the shell 21 and the inner tube 22, heat can be efficiently transferred to the water in the inner tube 22, thereby realizing rapid heating.

[0049] Optionally, as shown in Figure 2 , Figure 4 The base 4 is provided with a water pump 44, and the water pipeline 3 includes a first pipeline 31, a second pipeline 32 and a third pipeline 33. The first pipeline 31 is connected between the second water inlet 41 and the water inlet of the water pump 44. The second pipeline 32 is connected between the water outlet of the water pump 44 and the third water inlet 24. The third pipeline 33 is connected between the third water outlet 25 and the second water outlet 42.

[0050] Specifically, the water pump 44 serves as the power source of the system and is responsible for pumping and delivering water. The selection of the water pump 44 should be based on the required flow rate and pressure of the system. The first pipe 31 is connected between the second water outlet 42 and the water inlet of the water pump 44, ensuring that water can flow smoothly from the second water outlet 42 into the water pump 44, providing conditions for subsequent pressurization and delivery. The second pipe 32 is connected between the water outlet of the water pump 44 and the third water inlet 24. The water pressurized by the water pump 44 is sent to the third water inlet 24 through the second pipe 32, and then enters the subsequent heating process. The design of the second pipe 32 should consider the flow rate and pressure of the water, as well as the material and connection method of the pipe. The third pipe 33 is connected between the third water outlet 25 and the second water inlet 41. The water flowing out of the third water outlet 25 flows through the third pipe 33 and the second water inlet 41, and then flows into the water container 1, forming a closed-loop water circulation system.

[0051] In this optional embodiment, the water pipeline 3 is designed as multiple connected pipes, which facilitates installation and connection, as well as the connection between the water pump 44, the first heating body 2, and the water pipeline 3.

[0052] Optionally, as shown in Figure 2 the base 4 is provided with a controller, and the first pipe 31 is provided with a control valve 45. The control valve 45 and the water pump 44 are electrically connected to the controller.

[0053] Specifically, the control valve 45 is provided at the first pipe 31 to control the flow of fluid. The selection of the control valve 45 should be based on the material of the water pipeline 3 and the control requirements of the system. When the controller receives a signal indicating that it needs to be turned on or off, it will control the on-off state of the control valve 45 through an electrical signal, thereby achieving precise control of water flow. The water pump 44 serves as the power source of the system, and its working state also needs to be controlled by the controller. The water pump 44 is electrically connected to the controller, which can control the speed or start-stop of the water pump 44 through an electrical signal according to the system's requirements, such as changes in flow rate and pressure adjustments, to ensure that the water pump 44 can operate optimally under different working conditions, thereby improving the efficiency and stability of the system.

[0054] In this optional embodiment, the introduction of the controller and the control valve 45 enables more intelligent and flexible control of the system, which not only improves the automation level of the system but also reduces the difficulty and complexity of manual operation.

[0055] Optionally, as shown in Figure 3 the base 4 is provided with a controller, and the first pipe 31 is provided with a control valve 45. The control valve 45 and the water pump 44 are electrically connected to the controller.

[0056] Specifically, the control button group 46 serves as an interface for the user to interact with the system, allowing the user to input instructions or adjust parameters of the system by pressing different buttons. The instructions or parameters will be transmitted to the controller, which will control the system accordingly according to pre-set logic or algorithms. For example, the user can start or stop the system, adjust the heating temperature, set the working mode, etc. through the control button group 46. The temperature sensor is arranged in the water container 1 to monitor the water temperature in real time. When the water temperature changes, the temperature sensor will transmit the temperature information to the controller. The controller can determine whether the current water temperature meets the user's needs according to the received temperature information, and adjust the heating power or working mode of the second heating body accordingly. The liquid level sensor is used to monitor the change of water level in the water container 1. When the water level is too high or too low, the liquid level sensor will send a signal to the controller. The controller can determine whether to add water or stop heating, etc. according to the received liquid level information, to ensure the safe operation of the system.

[0057] In this optional embodiment, by introducing the control button group 46, the temperature sensor and the liquid level sensor, and realizing electrical connection with the controller, the entire system can more intelligently respond to the user's needs and environmental changes.

[0060] Although the utility model discloses as above, the protection scope of the utility model is not only limited to this. The person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
