[0028] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0029] Refer to the instruction manual appendix Figures 1-9 An electric heater includes a base 1 and a burner 3, with a wire mesh 2 disposed between the base 1 and the burner 3.
[0030] like Figure 6 and Figure 7 As shown, in the above technical solution, the burner head 3 includes a support 31, a steel ring 32 is provided at the upper end of the support 31, a carbon crystal heating plate 33 is provided inside the steel ring 32, a microcrystalline panel 34 is installed on the upper surface of the steel ring 32, the steel ring 32 and the carbon crystal heating plate 33 are both fixed to the support 31, and a metal decorative mesh 35 is fixedly installed at the bottom of the support 31.
[0031] It should be noted that the carbon crystal heating plate 33 is used for heating. When in use, the kettle can be placed on the microcrystalline panel 34 and heated by the carbon crystal heating plate 33, so that water can be boiled and warmth can be obtained at the same time. A mesh cover 6 is set above the steel ring 32. Covering the kettle with the mesh cover 6 can prevent accidental burns.
[0032] like Figure 6 and Figure 7 As shown, in the above technical solution, the inside of the wire mesh cage 2 is provided with a mica heating element 4, which includes a heating component 41. The heating component 41 is used for heating. A lower cover 42 is installed at the bottom of the heating component 41, and an upper cover 43 is installed at the top of the heating component 41. The upper cover 43 is installed at the bottom of the furnace head 3.
[0033] The heating element 41 includes a reverse barrel 411, with several insulating plates 412 mounted circumferentially on its outer side. Heating wires 413 are spirally arranged on the insulating plates 412. The heating wires 413 generate heat. The reverse barrel 411 is made of aluminum, and the insulating plates 412 are made of mica, serving as insulation. When the heating wires 413 are energized, they produce red light, and the reverse barrel 411 diffuses the generated heat outwards, thus providing warmth. It should also be noted that the upper end of the cover 43 has a ring-shaped plate 431, which can be mounted on the bracket 31 by screws.
[0034] The above technical solution uses a wire mesh cage 2 to reflect the heat generated by the heating wire 413 through the reverse barrel 411, thereby providing warmth to people. Compared with the existing technology that relies on the stove 3 for heating, the temperature is higher and the heating effect is better.
[0035] like Figure 2 and Figure 3 As shown, a ceramic tube 5 is provided in the middle of the mica heating element 4. The upper end of the ceramic tube 5 is installed on the burner head 3, and the lower end of the ceramic tube 5 is installed on the base 1. The ceramic tube 5 is used to run the power cord of the burner head 3.
[0036] It should be noted that the upper end of the ceramic tube 5 is installed in the middle of the bracket 31 by a nut, and the power cord of the burner head 3 passes through the ceramic tube 5 from the position of the base 1 and is connected to the carbon crystal heating plate 33 and the microcrystalline panel 34. The ceramic tube 5 can play the role of insulation and heat insulation.
[0037] like Figure 8 and Figure 9 As shown, the base 1 includes a support base 11, an LED aperture 12 is installed inside the support base 11, a light-transmitting cover 13 is provided at the upper end of the support base 11, the LED aperture 12 is located inside the light-transmitting cover 13, and the bottom of the ceramic tube 5 is fixedly installed with the support base 11.
[0038] It should be noted that the light-transmitting cover 13 is made of red blister material. When the LED aperture 12 is powered on and emits light, the light can pass through the light-transmitting cover 13, thereby simulating the visual effect of burning charcoal.
[0039] Furthermore, such as Figure 3 As shown, a bottom cover 14 is installed at the bottom of the support base 11. During maintenance, the bottom cover 14 can be opened for maintenance, which is relatively convenient.
[0040] like Figures 1-3 As shown, the wire mesh cage 2 is supported on the support base 11, and the upper end of the wire mesh cage 2 is located inside the steel ring 32.
[0041] It should be noted that the mesh cage 2 is a metal mesh structure, and the heat emitted by the mica heating element 4 can diffuse outward for heating. During assembly, first assemble the ceramic tube 5, the mica heating element 4 and the burner head 3. After supporting the mesh cage 2 on the support base 11, support the burner head 3 on the mesh cage 2. At this time, insert the ceramic tube 5 into the support base 11 and fix the ceramic tube 5 and the support base 11 with screws. After connecting the power cord of the burner head 3 to the circuit board in the support base 11, install the bottom cover 14.
[0042] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
