Description

[Technical field]

[0001] The utility model relates to the technical field of steam generators, in particular to an inflation type steam generator. [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 and resistance wires to heat the flowing liquid. The heating efficiency is low and the structure is complex, which makes the product assembly and application troublesome.

[0003] Meanwhile, there is also a method in the prior art of using a steam generator structure to heat the liquid flowing in its internal channel. However, although the existing steam generator structure solves the problem of troublesome product assembly and application, the production and processing technology of the existing steam generator structure is relatively complicated. It is necessary to first die-cast a channel on the substrate, and then weld and seal the edges of the two substrates. The sealing of the internal channel and the edges of the substrate is poor. During processing, the thickness and flatness of the substrate are required to be high, and the yield rate is low, resulting in high production costs, which is not conducive to promotion and application. Moreover, the thick substrate reduces the heating and heat transfer efficiency, making it difficult to achieve instant heating effects.

[0004] In order to solve the above problems, the utility model provides an inflation type steam generator. [Contents of the utility model]

[0008] The inflation-type steam generator as described above is characterized in that the thickness of the first substrate does not exceed the thickness of the second substrate, and the channel protrudes from the upper surface of the first substrate.

[Specific implementation method]

[0022] The technical features of the present invention are further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand them.

[0023] An expansion steam generator, such as Figure 1 to Figure 4 As shown, it includes a first substrate 1 and a second substrate 2 that are resistant to high temperatures. The first substrate 1 and the second substrate 2 are pressed and sealed by a hot pressing process. A channel 3 for circulating liquid or steam generated by a blowing process is provided on the first substrate 1. A liquid inlet 4 for flowing liquid and an outlet 5 for leading out heated liquid or steam are provided on the first substrate 1 and at the initial end and the end of the channel 3, respectively. A graphene heating coating 6 for heating the liquid in the channel 3 is provided on the bottom surface of the second substrate 2. The first substrate 1 and the second substrate 2 are first pressed and sealed by a hot pressing process to ensure the sealing of the edges of the substrates, and then a blowing process is used. , the pressed substrate with the channel pattern engraved thereon is inflated by using high-pressure gas, so that a channel 3 with good sealing performance can be easily inflated on the first substrate 1, and then the redundant edges and corners are cut off to expose the liquid inlet 4 and the outlet 5, and then the graphene heating coating 6 is coated, and the conduit 11 is sealed and connected. The above processing steps are relatively simple, the production yield is high and the production efficiency is high, which can reduce the production cost, and the steam generator has a simple structure and can be flexibly and widely used in various electric heating products. At the same time, the substrate used in the inflation process is thinner and has faster heat conduction. The graphene heating coating 6 has high heating efficiency and can easily achieve instant heating effect.

[0024] Specifically, the thickness of the first substrate 1 does not exceed the thickness of the second substrate 2, so that the high-pressure gas can blow out the channel 3 toward the first substrate 1 during the inflation process, thereby avoiding deformation of the second substrate 2 and affecting the flatness of its bottom surface. The channel 3 protrudes from the upper surface of the first substrate 1, and the bottom surface area of ​​the second substrate 2 corresponding to the graphene heating coating 6 is a plane or a smooth curved surface, which is convenient for coating the graphene heating coating 6.

[0025] Specifically, Figure 3 As shown, the graphene heating coating 6 includes a first insulating coating 7 directly coated on the bottom surface of the second substrate 2 and adhered thereto, a graphene coating 8 for generating heat is provided on the outer surface of the first insulating coating 7, a second insulating coating 9 is provided on the outer surface of the graphene coating 8, and electrode sheets 10 for conducting electricity are provided at both ends of the graphene coating 8.

[0026] Specifically, Figure 3 As shown, the materials of the first insulating coating 7 and the second insulating coating 9 are both insulating resins, and the first insulating coating 7, the graphene coating 8 and the second insulating coating 9 are sequentially superimposed on the bottom surface of the second substrate 2 in a coating manner, and the area of ​​the graphene coating 8 and the electrode sheet 10 does not exceed the area of ​​the first insulating coating 7 to prevent the electrode sheet 10 from contacting and leaking electricity with the second substrate 2.

[0027] Specifically, a conduit 11 is provided in the liquid inlet 4 and the outlet 5, and the connection between the conduit 11 and the liquid inlet 4 and the outlet 5 is sealed. The conduit 11 facilitates the steam generator to be connected to the applied electrical appliance, so as to facilitate assembly and application.

[0028] In addition, a temperature sensor 12 is provided on the first substrate 1 or the second substrate 2 and is located in the corresponding areas of the liquid inlet 4 and the outlet 5, respectively. The temperature sensor 12 is used to detect the temperature of the liquid flowing into the liquid inlet 4 and the temperature of the liquid or steam flowing out of the outlet 5, so that the steam generator can be used in products such as water heaters, coffee machines, and irons.

[0029] Specifically, the first substrate 1 and the second substrate 2 are made of metal or alloy with strong ductility, such as aluminum, copper or aluminum alloy, copper alloy and the like.

[0030] 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 heating coating 6, the steam generator can adopt a double-sided channel structure to improve heat utilization.

[0031] The embodiments described in the present invention are merely descriptions of preferred implementations and are not limited to the precise structures described above and shown in the accompanying drawings. Without departing from the design concept of the present invention, various modifications and improvements made to the technical solutions of the present invention by engineers and technicians in this field should fall within the protection scope of the present invention.
