[Technical field]
[0001] The utility model relates to the technical field of steam generators, in particular to a novel steam generator which adopts graphene heating. [Background technology]
[0002] In daily life, electric heating products such as coffee machines, instant water heaters, irons, and hanging irons are widely used; these traditional electric heating products usually use electric heating elements such as heating tubes, resistance wires, and thick film heating plates to heat the flowing liquid in the steam generator structure. The production and assembly of this type of steam generator is relatively troublesome, and the production and assembly efficiency is low, resulting in high production costs, which is not conducive to promotion and application. Moreover, since the various electric heating elements cannot be completely fitted with the substrate in the steam generator structure, the heating and heat transfer efficiency are poor, resulting in a slow temperature rise rate of the liquid in the steam generator, making it difficult to quickly achieve an instant heating effect.
[0003] In order to solve the above problems, the utility model provides a novel steam generator using graphene heating. [Contents of the utility model]

Finally, the first insulating coating 6, the graphene coating 7 and the second insulating coating 8 are sequentially coated on the bottom surface of the second substrate 2 through a coating process. The steam generator has a simple structure and can be flexibly and widely used in various electric heating products. The processing technology used is relatively mature and the processing steps are relatively simple, the production efficiency is high, and the production cost can be reduced. Moreover, compared with electric heating elements such as heating tubes, resistance wires, and thick film heating sheets, the graphene coating 7 has a high heating efficiency. The coating method makes the graphene coating 7 completely fit the second substrate 2, and the heat conduction is fast, which can quickly increase the liquid temperature in the channel 3 to achieve an instant heating effect.
[0021] Specifically, the bottom surface of the first substrate 1 fits with the upper surface of the second substrate 2, which can enhance the sealing between the channels 3 and allow more liquid or steam to flow along the channels 3. The edges of the first substrate 1 and the second substrate 2 are sealed and connected by welding or hot melting.
[0022] Specifically, Figure 3As shown, the materials of the first insulating coating 6 and the second insulating coating 8 are both insulating resins, and the first insulating coating 6, the graphene coating 7 and the second insulating coating 8 are sequentially superimposed on the bottom surface of the second substrate 2 in a coating manner, and the area of the graphene coating 7 and the electrode sheet 9 does not exceed the area of the first insulating coating 6 to prevent the electrode sheet 9 from contacting and leaking the second substrate 2.

[0025] In addition, if Figure 4 As shown, a structure identical to and symmetrical to the first substrate 1 and the second substrate 2 is provided on the side of the graphene heating coating 6 away from the second substrate 2. Due to the double-sided heating characteristic of the graphene coating 7, the steam generator can adopt a double-sided channel structure to improve the utilization rate of heat, so as to make full use of the heat generated by the graphene coating 7 and increase the flow rate of liquid or steam in the channel 3.
