[0030] Reference Figure 1 An electric thermos includes a base 100, a warm water container 500, and a hot water container 300. The base 100 is provided with a water outlet 130. The warm water container 500 is mounted on the base 100 and connected to the water outlet 130. The hot water container 300 is mounted on the base 100, and at least one of the water outlet 130 and the warm water container 500 is connected to the hot water container 300. The fluid in the hot water container 300 can mix with the fluid in the warm water container 500 and flow out of the water outlet 130. The hot water container 500 and the hot water container 300 can each be loaded with fluids of different temperatures. The hot water container 300 can transfer its loaded fluid to the warm water container 500 and gradually cool it, thereby causing a temperature difference between the fluid in the hot water container 300 and the fluid in the hot water container 500. Therefore, users can choose to take fluid from either the hot water tank 300 or the warm water tank 500 according to different needs, or they can mix the water at the water outlet 130 as needed to obtain fluid with a temperature between the two, thereby meeting the user's different fluid temperature needs. Therefore, the electric thermos is provided with a hot water tank 300 and a warm water tank 500, and the two can discharge water separately or mixedly, thereby meeting various water temperature requirements, and bringing the advantages of flexible use, avoiding frequent heating of water or waiting for cooling, and energy saving and high efficiency, thereby improving the user experience.

[0031] Specifically, the outer periphery of the hot water container 300 is covered with thermal insulation cotton, and the temperature state thereof is maintained by the thermal insulation cotton.

[0032] In certain embodiments, reference Figure 4 At least one of the hot water container 300 and the warm water container 500 is provided with a temperature sensing device 320. The temperature sensing device 320 can sense and detect the temperature of the fluid in the hot water container 300 or the warm water container 500, thereby facilitating timely heating of the hot water container 300 or the warm water container 500, thereby ensuring that the fluid in the hot water container 300 or the warm water container 500 is maintained at a predetermined temperature. In addition, the temperature sensing device 320 can also transmit the temperature information of the fluid in the hot water container 300 or the warm water container 500 to the user, thereby facilitating the user to understand the temperature conditions of the two, and further facilitating the user to mix the fluid in the hot water container 500 and the fluid in the hot water container 300 to the desired temperature.

[0033] Specifically, the temperature sensing device 320 may be a temperature sensor. Of course, the temperature sensing device 320 may also be other components. The specific implementation is not unique and can be adjusted accordingly according to actual conditions, and is not limited here.

[0034] In certain embodiments, reference Figure 4At least one of the hot water tank 300 and the warm water tank 500 is equipped with an electric heating element, and the temperature sensing device 320 is electrically connected to the temperature gear circuit and communicates with the electric heating element through the temperature gear circuit. The electric heating element can heat the hot water tank 300 or the warm water tank 500, so that the fluid inside it can be promptly returned to a predetermined temperature. Under the cooperation of the temperature sensing device 320 and the electric heating element, when the fluid inside the hot water tank 300 or the warm water tank 500 cools due to heat dissipation, the temperature sensing device 320 can promptly detect the temperature drop of the fluid and transmit a signal to the electric heating element, so that the electric heating element can promptly heat the hot water tank 300 or the warm water tank 500, so that the fluid inside it can quickly return to a predetermined temperature, thereby smoothly ensuring that the fluid inside the hot water tank 300 or the warm water tank 500 is in a constant temperature state.

[0035] Specifically, the temperature control circuit includes a multi-level temperature control program. The user can select different temperature levels, and the temperature control program can calculate the required temperature and flow rate of the hot water tank 300 and the warm water tank 500 according to the user's selected target temperature, thereby automatically providing fluids at different temperatures.

[0036] Specifically, refer to Figure 6 , both the hot water container 300 and the warm water container 500 are provided with electric heating elements, wherein the electric heating element provided in the hot water container 300 is an electric heating tube 331, and the electric heating element provided in the warm water container 500 is a PTC heating element 332. Of course, at least one of the hot water container 300 and the warm water container 500 may be provided with an electric heating tube 331 and a PTC heating element 332. In addition, only the hot water container 300 or only the warm water container 500 may be provided with an electric heating element. In the case where only the warm water container 500 is provided with an electric heating element, the hot water container 300 can heat the fluid inside it by supplementing high-temperature fluid. The specific implementation method is not unique, but can be adjusted accordingly according to actual circumstances, and is not limited here.

[0037] Furthermore, the base 100 is provided with a cover 150, which seals the hot water container 300. When the cover 150 is opened, the user can directly add fluid into the hot water container 300, thereby quickly and conveniently replenishing the fluid.

[0038] In certain embodiments, reference Figure 2A cooling water channel 700 is provided between the hot water container 300 and the warm water container 500. The hot water container 300 is connected to the warm water container 500 through the cooling water channel 700 and can transport fluid thereto. The hot water container 300 can transport fluid to the warm water container 500 through the cooling water channel 700, thereby replenishing the fluid in the warm water container 500. The cooling water channel 700 can cool the fluid during the process of transporting the fluid from the hot water container 300 to the warm water container 500, thereby ensuring that there is a temperature difference between the fluid in the hot water container 300 and the fluid in the warm water container 500, thereby ensuring that the user can obtain fluids of different temperatures from the hot water container 300 and the warm water container 500 respectively.

[0039] In certain embodiments, reference Figure 3 The cooling water path 700 includes a spiral tube 710 installed around the outer periphery of the warm water container 500. The hot water container 300 is connected to the warm water container 500 through the spiral tube 710, and the spiral tube 710 can exchange heat with the outside world. The spiral tube 710 not only smoothly connects the hot water container 300 and the warm water container 500, but also effectively prolongs the flow time of the fluid, thereby facilitating heat exchange between the fluid and the outside world through the spiral tube 710, thereby smoothly achieving the effect of cooling the fluid.

[0040] In certain embodiments, reference Figure 5 A solenoid valve 410 is provided between the hot water container 300 and the warm water container 500. The solenoid valve 410 is connected to the spiral tube 710 and can switch the connecting state and the closing state of the spiral tube 710. The solenoid valve 410 can quickly and effectively open or close the fluid transmission state between the hot water container 300 and the warm water container 500, thereby preventing excessive hot water in the hot water container 300 from flowing into the warm water container 500 and causing temperature imbalance or excessive or insufficient fluid volume.

[0041] Specifically, the solenoid valve 410 has a control program. When and only when the temperature sensing device 320 detects that the temperature of the fluid in the warm water container 500 is lower than 55°, the solenoid valve 410 opens and allows the fluid in the hot water container 300 to flow into the warm water container 500.

[0042] Furthermore, the solenoid valve 410 may also be opened once every fifteen minutes to ensure that the fluid in the warm water tank 500 maintains a predetermined amount and temperature.

[0043] In certain embodiments, reference Figure 5 A tube clamp 720 is installed on the outer periphery of the warm water container 500, and the spiral tube 710 is installed on the tube clamp 720 and fixed relative to the warm water container 500. The tube clamp 720 can fix and support the spiral tube 710, so that the spiral tube 710 can be stably installed on the outer periphery of the warm water container 500, thereby preventing the spiral tube 710 from loosening or falling.

[0044] In certain embodiments, reference Figure 2 The warm water container 500 and the hot water container 300 are both connected to the water outlet 130, and the fluid in the warm water container 500 and the fluid in the hot water container 300 can be mixed at the water outlet 130. When the user obtains the fluid from the water outlet 130, the mixed fluid can be directly obtained without the user having to mix the fluid in the hot water container 300 and the fluid in the warm water container 500 by themselves, thereby providing convenience for the user's use process.

[0045] In certain embodiments, reference Figure 1 The base 100 is provided with a three-way pipe 600, to which both the hot water container 300 and the warm water container 500 are connected; the three-way pipe 600 is installed at the front end of the water outlet 130. The fluid in the hot water container 300 and the fluid in the warm water container 500 can flow into the three-way pipe 600 and then flow to the water outlet 130 through the three-way pipe 600 to mix, so that the user can take it out.

[0046] Specifically, refer to Figure 7 The three-way pipe 600 is provided with two water inlets 610, which are respectively connected to the warm water tank 500 and the hot water tank 300. The three-way pipe 600 is connected to a connecting pipe 650 for diversion, and the connecting pipe 650 is connected to the water outlet 130.

[0047] Furthermore, a digital display screen 170 is provided on the base 100, and the user can select the outlet water temperature at the water outlet 130 according to the temperature information provided by the digital display screen 170. The temperature settings that can be provided include 95°, 85°, 70°, 65°, 55° and 45°.

[0048] In certain embodiments, reference Figure 3 At least one of the warm water tank 500 and the hot water tank 300 is connected to a water pump 420. The water pump 420 can effectively extract the fluid in the warm water tank 500 or the hot water tank 300 so that it can flow smoothly, and then can effectively transport the fluid in the hot water tank 300 or the hot water tank 500 to the water outlet 130.

[0049] It is envisioned that the amount of fluid flowing from the hot water container 300 and the warm water container 500 to the tee 600 may be controlled by the water pump 420, or that other valves may be separately installed at the tee 600 to control the amount of fluid flowing from the hot water container 300 and the warm water container 500 to the tee 600. The specific implementation is not exclusive and can be adjusted accordingly according to actual circumstances, and is not limited here.

[0050] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the scope of the present invention.
