[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figure 1 , shows a schematic structural diagram of an electric water heater embodiment of the present invention, comprising at least one heating module 101, whose output port 102 is connected to the collecting input port 203 of the water outlet tank 201, and whose input port 103 is connected to the diverting output port 304 of the water inlet tank 301; the water outlet tank 201 is provided with a water outlet 202, and the water inlet tank 301 is provided with a water inlet 302; the heating module 101 comprises an outer shell 104; inner covers 106 are provided at both ends of the outer shell 104, and the inner covers 106 An outer cover 105 is provided on the outer side; a buffer space is provided between the outer cover 105 and the inner cover 106, and openings are distributed in an equilateral triangle on the inner cover 106, and electric heating tubes 108 are sealed and connected between the openings; wherein, the outer cover 105 at one end of the heating module 101 is provided with an output port 102, and the other end is provided with an input port 103; the electric heating tube 108 has a nano heating film 181 on its surface, and electrodes 182 at both ends thereof; the electrodes 182 are electrically connected to a power source outside the outer shell 104.

[0020] In this embodiment, an electric water heater is proposed, which aims to improve the heating efficiency by including at least one heating module 101 system, especially in heating applications, to solve the problem of slow heating of the liquid circulation system. Specifically, at least one heating module 101 is used, and the heating area and heat exchange efficiency are improved by parallel connection. The setting of multiple furnace bodies makes the heat distribution more uniform, reduces the waste of heat energy, and thus improves the overall heating efficiency; the output port 102 and the input port 103 of the heating module 101 are respectively connected to the water outlet tank 201 and the water inlet tank 301 so that a buffer is formed during input and output; the surface of the electric heating tube 108 is covered with a nano heating film 181, which has high thermal conductivity and fast heating characteristics, and can quickly convert electrical energy into thermal energy, significantly improving the heating speed. Multiple heating tubes are conducive to uniform heat distribution during heating, further improving the uniformity and efficiency of heating. The above-mentioned outer shell 104 can also reduce the temperature spilling to the outside of the outer shell 104, so that it has a certain insulation function, reduces energy loss, and thus achieves efficient heating.

[0021] Advantageously, the water inlet tank 301 is disposed at the lower end of the heating module 101, and the water outlet tank 201 is located at the upper end of the heating module 101, so that the water path runs from the water inlet tank 301 below to the heating module 101 and then to the water outlet tank 201, so that the water can fully fill the interior of the heating module 101, avoiding the possibility of uneven water inlet or the heating module 101 caused by the water inlet method from top to bottom, so that the water therein can be fully heated.

[0022] In one embodiment of the present application, the nano-heating film 181 on the surface of the electric heating tube can be a graphene heating film. Graphene itself is a two-dimensional material composed of a single layer of carbon atoms arranged in a honeycomb shape, and its thickness is at the nanometer level. The graphene heating film is usually composed of multiple layers of graphene nanosheets, which are stacked on each other by van der Waals forces. The nanoscale structure of graphene gives the heating film excellent electrical conductivity and thermal conductivity, so that the graphene heating film performs well in electrothermal conversion and heat transfer. Specifically, the graphene heating film has very good thermal conductivity and can transfer heat quickly and evenly. On the one hand, the electric heat conversion rate of the graphene heating film can reach more than 90%, and almost all electrical energy can be converted into thermal energy, which improves the heating efficiency; on the other hand, the graphene heating film has no harmful electromagnetic radiation when working, and there is no exhaust gas, wastewater, noise, etc., which is a green and environmentally friendly heating method; on the other hand, the graphene heating film has excellent flexibility and corrosion resistance, and can adapt to various complex use environments. In addition, the service life of the graphene heating film can reach more than 200,000 hours, showing its durability; the graphene heating film usually has self-fusing technology, which can automatically cut off the power supply when the temperature is too high, improving the safety of use. In addition, the graphene heating film is combined with an intelligent temperature control system, which can adjust the temperature as needed, avoid unnecessary energy waste, and realize energy-saving intelligent heating.

[0023] In one embodiment of the present application, Figures 1 to 4 As shown, a drain port 303 is also provided at the bottom of the water inlet tank 301. The drain port 303 can be connected to a drain pipe through a valve. For example, when boiling water for a long time, silt residue and the like may appear in the water inlet tank 301. By opening the valve, the silt residue and other debris can be discharged from the drain port 303. The structure of the drain port 303 allows the user to more conveniently discharge the liquid and dirt in the electric water heater, which is particularly important for maintaining and cleaning the electric water heater. For example, in industrial production or large commercial facilities, regular discharge and replacement of liquid can ensure the efficient operation of the electric water heater and extend its service life.

[0024] In one embodiment of the present application, Figure 6 As shown, a support rod 107 is provided inside the outer shell 104 and between the inner cover 106. The addition of the support rod 107 enhances the structural stability of the heating module.

[0025] In one embodiment of the present application, a sealing gasket 109 is provided between the electric heating tube 108 and the opening to ensure the sealing performance of the electric heating tube 108 .

[0026] In one embodiment of the present application, the collecting input port 203 of the water outlet tank 201 is connected to the output port 102 via an output connecting pipe 401; the diverting output port 304 of the water inlet tank 301 is connected to the input port 103 via an input transfer pipe 501. Through the output connecting pipe 401 and the input transfer pipe 501, the distance and position between the water outlet tank 201 and the water inlet tank 301 and the heating module 101 are adjustable, and both the output connecting pipe 401 and the input transfer pipe 501 can use a hose.

[0027] In one embodiment of the present application, Figure 3 As shown, the heating modules 101 are provided in three numbers, and the corresponding water outlet tank 201 is provided with three collecting inlets 203, and the water inlet tank 301 is provided with three dividing outlets 304. Figure 3 As shown, the number of heating modules 101 is four, and the corresponding water outlet tank 201 is provided with four collecting inlets 203, and the water inlet tank 301 is provided with three diverting outlets 304. Increasing the number of heating modules 101 can further improve the heating efficiency and the overall heat exchange capacity of the system. For example, in large-scale heating systems or industrial applications that require rapid heating of large amounts of water, a multi-heating module design can provide greater heating capacity.

[0028] In one embodiment of the present application, a box 601 is further included; the heating module 101, the water outlet tank 201 and the water inlet tank 301 are all arranged in the box 601; wherein the water outlet 202 and the water inlet 302 are both extended out of the box; and a control component for controlling heating is also arranged on the box 601. Through the structure of the box 601, a packaging environment is provided to protect the internal components from the influence of the external environment, and at the same time, it is convenient to integrate the control components to realize automatic control.

[0029] In one embodiment of the present application, Figure 7 As shown, the lower end of the box body 601 is also provided with a support foot 602. Through the support foot 602, the bottom of the box body 601 is kept at a certain distance from the ground, and the electric water heater can stand stably on the ground to ensure the safe operation of the equipment.

[0030] In one embodiment of the present application, the electrode 182 is a silver paste electrode. The silver paste electrode has good electrical conductivity and high temperature resistance, and can improve the heating efficiency and reliability of the electric water heater. In particular, in a high temperature working environment, such as in industrial heat treatment equipment, the silver paste electrode can ensure the stability and life of the electrode at high temperatures.
