[0048] The liquid heating device according to the embodiments of the present application is described below.

[0049] The liquid heating device according to the embodiments of the present application is described below.

[0050] The liquid heating device according to the embodiments of the present application is described below.

[0051] It can be understood that the present application significantly improves the heat exchange efficiency by first converting the high-temperature liquid into water mist and then cooling in the water mist state. The surface area of the water mist is much larger than that of the same volume of liquid water, so it can exchange heat with the air or cooling medium (such as the condensate plate 520) in the cooling cavity 501 more quickly, achieving rapid cooling.

[0052] According to an embodiment of the present application, the collection container 500 includes a container body 510 connected to the atomizing nozzle 400 and a condensate plate 520 connected to the container body 510 and disposed on the opposite side of the atomizing nozzle 400, and a cooling cavity 501 is formed between the condensate plate 520 and the container body 510.

[0053] It can be understood that the condensate plate 520 is disposed inside the collection container 500 on the opposite side of the atomizing nozzle 400, which can increase the contact area of the water mist with the air, promote the condensation and cooling of the water mist, and reduce the splashing of the water mist. The water mist is further dispersed and attached to the surface of the condensate plate 520 after being sprayed onto it, prolonging the contact time with the air and thus improving the cooling effect. The surface temperature of the condensate plate 520 is relatively low, which is conducive to the condensation of water vapor in the water mist into liquid water and accelerates the conversion process of the water mist to liquid.

[0054] According to an embodiment of the present application, the cooling cavity 501 includes a first cooling cavity 512 and a second cooling cavity 513, the first cooling cavity 512 and the second cooling cavity 513 are disposed along the height direction of the container body 510, the first cooling cavity 512 is disposed above the second cooling cavity 513, the first cooling cavity 512 is communicated with the second cooling cavity 513, the container body 510 includes an interface part 511 for connecting the pipeline 200, and the interface part 511 is communicated with the first cooling cavity 512.

[0055] It can be understood that the liquid in the pipeline 200 is suitable for entering the first cooling cavity 512 through the interface part 511, and the liquid can flow downward to the second cooling cavity 513 below by the action of gravity.

[0056] According to an embodiment of the present application, the container body 510 includes a cooling body part 514, the interface part 511 is connected to the cooling body part 514, the interface part 511 is protruded relative to the cooling body part 514, the interface part 511 is provided with a converging structure inclined relative to the horizontal plane, and the converging structure is directed towards the first cooling cavity 512.

[0057] It can be understood that the interface part 511 is provided with a converging structure inclined relative to the horizontal plane, which is helpful for converging the water mist sprayed by the atomizing nozzle 400 onto the cooling cavity 501, thereby improving the overall cooling efficiency.

[0058] According to an embodiment of the present application, the liquid heating device comprises a fan 600 arranged on the collection container 500, and the fan 600 is used to take away the heat of the condensate plate 520.

[0059] The fan 600 is a device for generating air flow. In the present embodiment, the fan 600 is installed on the collection container 500 and used to take away the heat of the condensate plate 520 and its surrounding environment, accelerating the cooling process of the water mist.

[0060] It can be understood that by arranging the fan 600 in the collection container 500, the hot air in the cooling cavity 501 can be actively taken away, thereby accelerating the process of condensing the water mist on the condensate plate 520 into liquid water. The fan 600 reduces the temperature of the condensate plate 520 and its surrounding environment, so that the water mist can release heat faster and be converted into liquid, significantly improving the cooling efficiency.

[0061] According to an embodiment of the present application, the fan 600 is a centrifugal fan 600. It can be understood that the centrifugal fan 600 can effectively suck air from the air inlet and accelerate it through the rotating impeller before discharging it from the air outlet. In the cooling of the liquid heating device of the present application, the centrifugal fan 600 can provide stable and efficient air flow delivery, ensuring that the hot air in the cooling cavity 501 is taken away in time, thereby enhancing the cooling effect.

[0062] According to an embodiment of the present application, a guide plate 700 is arranged between the air outlet of the fan 600 and the cooling cavity 501, and the guide plate 700 is used to guide the air to the side of the condensate plate 520 away from the cooling cavity 501.

[0063] It can be understood that by arranging the guide plate 700 between the air outlet of the fan 600 and the cooling cavity 501, it can be ensured that the air flow generated by the fan 600 is directed to the side of the condensate plate 520 away from the cooling cavity 501, so that the air flow can directly act on the high-temperature surface of the condensate plate 520, improving the heat exchange efficiency and accelerating the cooling of the water mist on the condensate plate 520.

[0064] According to an embodiment of the present application, the liquid heating device comprises a plurality of heat dissipation fins 800 connected to the side of the condensate plate 520 away from the cooling cavity 501.

[0065] It can be understood that the heat dissipation fins 800 are connected to the plate-like or sheet-like structure on the side of the condensate plate 520 away from the cooling cavity 501, which is used to increase the heat dissipation area and improve the heat exchange efficiency. The heat dissipation fins 800 have good thermal conductivity and aerodynamic performance, which can effectively transfer the heat on the condensate plate 520 to the air and accelerate the cooling process. By connecting a plurality of heat dissipation fins 800 to the side of the condensate plate 520 away from the cooling cavity 501, the heat dissipation area can be significantly increased, thereby improving the heat dissipation effect.

[0066] According to an embodiment of the present application, the collection container 500 is provided with a liquid outlet 530, which is in communication with the cooling cavity 501 and is arranged at the bottom of the collection container 500.

[0067] It can be understood that the liquid outlet 530 refers to an opening or a pipe 200 on the collection container 500 for discharging the cooled liquid. In this embodiment, the liquid outlet 530 is arranged at the bottom of the collection container 500 and is in communication with the cooling cavity 501, so as to smoothly discharge the cooled liquid. The condensed liquid can spontaneously flow to the liquid outlet 530 at the bottom of the collection container 500 by its own gravity. This reduces the residue and waste on the inner wall of the container. This helps to keep the collection container 500 clean and improves the utilization rate of the cooled liquid.

[0068] According to an embodiment of the present application, the liquid heating device comprises a plurality of water baffles 900 arranged on the path from the atomizing nozzle 400 to the liquid outlet 530.

[0069] It can be understood that the water baffles 900 increase the flow path of the liquid on the path from the atomizing nozzle 400 to the liquid outlet 530, so that the water droplets after atomization stay in the space for a longer time, thereby having more opportunities for heat exchange with the cooling medium (such as air). This extended heat exchange time helps to improve the cooling efficiency, so that the liquid can be more fully cooled.

[0070] The design of the water baffles 900 can be adjusted and optimized according to specific application scenarios and requirements. For example, the number, position, angle and shape of the water baffles 900 can be changed to adapt to different cooling requirements and space limitations. This flexibility makes the device design more flexible and diverse, and can meet the needs of different users.

[0071] Specifically, the water baffles 900 can form a circuitous water path, and the hot water flowing in the water path can flow downward by its own gravity.

[0072] According to an embodiment of the present application, the liquid heating device comprises a pump body 300 arranged in the pipe 200, for pumping the heated liquid from the liquid storage container 100 to the atomizing nozzle 400.

[0073] It can be understood that the pump body 300 is arranged in the pipe 200, and its main function is to provide power to pump the heated liquid from the liquid storage container 100 and deliver it to the atomizing nozzle 400 through the pipe 200. This process realizes the circulating flow of the liquid, ensuring that the liquid can continuously receive heating and be converted into mist for cooling.

[0074] Through the action of the pump body 300, the heated liquid can be quickly pumped out and subjected to atomization treatment again, thereby improving the efficiency of the entire heating process. This helps to reduce the heating time, reduce energy consumption, and enable the liquid to reach the required temperature faster.

[0075] It should be noted that in the related art, hot boiled water is usually cooled by forcibly air cooling the outer wall of the liquid storage container 100. However, this scheme has low efficiency and a long cooling time because the liquid is stationary in the liquid storage container 100 and the outer wall of the liquid storage container 100 is directly air cooled.

[0076] The present application proposes a liquid heating device that can convert between gas and liquid, which realizes instant and rapid cooling in the process of hot water changing from liquid state to gaseous state and then from gaseous state to liquid state. The hot boiled water is converted from liquid state to high-temperature gaseous water mist by using a water pump and a high-pressure atomizing nozzle 400, the water mist is sprayed onto the surface of the condensate plate 520 with a lower temperature, the condensation of the water mist releases heat and changes from gaseous state to liquid state; at the same time, the condensate plate 520 transfers heat to the heat dissipation blades 800, and the condensate liquid water flows through the scattering area formed by the water baffles 900, which increases the heat exchange area and further transfers heat to the heat dissipation blades 800, the air flow provided by the fan 600 can take away the heat of the heat dissipation blades 800 and the condensate plate 520, thereby realizing rapid cooling of the liquid.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the present application, but not to limit the present application. Although the present application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present application do not deviate from the spirit and scope of the present application, and should be covered in the scope of the claims of the present application.
