[0024] As Figures 1-5 shown, the present application provides a technical solution: a multi-heating pipe electric heating pot base, comprising an electric heating pot body 1, a pot part support 101, a pot part base 102 and a heating disc 103, the lower end of the electric heating pot body 1 is fixedly connected with the pot part support 101, the lower end of the pot part support 101 is fixedly connected with the pot part base 102, and the lower side of the electric heating pot body 1 is provided with the heating disc 103;

[0025] The heating disc 103 is composed of multiple groups of heating pipes, the multiple groups of heating pipes are arranged in a spiral shape, the lower wall of the electric kettle body 1 is provided with a clamping groove 2, the upper half of the heating disc 103 is clamped and installed in the inside of the clamping groove 2, the inside of the kettle part supporting bracket 101 is provided with a fixed plate 201, the inside of the fixed plate 201 is provided with multiple groups of connecting grooves 209, the multiple groups of connecting grooves 209 are penetrated by multiple groups of connecting columns 202, the upper ends of the two groups of connecting columns 202 are fixedly connected with a group of heating discs 103, the thickness of the fixed plate 201 is less than the length of the connecting column 202, the inner wall of the kettle part supporting bracket 101 is provided with four groups of limiting grooves 204, the inside of the four groups of limiting grooves 204 is respectively provided with a group of extension springs 205, one end of the extension spring 205 is fixedly connected with the inner wall of the kettle part supporting bracket 101, the other end of the extension spring 205 is connected with a limiting block 206, the inside of the kettle part supporting bracket 101 is communicated with the connecting column 202 through a line.

[0026] According to the overall structure of the device, the multiple groups of heating pipes are combined to form the heating disc 103, which can make the heat more evenly distributed on the bottom of the kettle, effectively solve the problem of center overheating and edge underheating caused by single heating pipe design, and change the installation mode of the heating pipe, so that the heating pipe can be quickly disassembled and replaced after being damaged, avoid the situation that the whole kettle is scrapped due to the failure of the heating pipe, greatly reduce the maintenance cost and replacement cost of the user, and improve the overall reliability and economy of the product.

[0027] As shown in Figure 2 , the upper wall of the fixed plate 201 is provided with a concave arc groove matched with the heating disc 103, and the lower half of the heating disc 103 is clamped and installed in the concave arc groove.

[0028] By providing the concave arc groove on the upper wall of the fixed plate 201, the heating disc 103 can be more tightly installed with the electric kettle body 1, and the movement of the heating disc 103 can be avoided.

[0029] As shown in Figure 2 , the material of the fixed plate 201 is alumina ceramic material, and the upper wall of the fixed plate 201 is uniformly coated with a coating material of polytetrafluoroethylene material.

[0030] By designing the material of the fixed plate 201 as alumina ceramic material and coating the surface wall with a coating material of polytetrafluoroethylene material, the fixed plate 201 can not only withstand high temperature, but also avoid damage caused by bumps, and the overall cost is relatively low.

[0031] As shown in Figure 4 , the lower wall of the fixed plate 201 is fixedly connected with a handle 208, and the material of the handle 208 is plastic material.

[0032] By installing the handle 208 on the lower wall of the fixed plate 201, the fixed plate 201 can be pulled to maintain the internal heating disc 103.

[0033] As Figure 4 shown, the inside of the connecting groove 209 is provided with a sealing sleeve 203, the material of the sealing sleeve 203 is silicone rubber material, the inside of the pot part support 101 is provided with thermal insulation cotton 207, the material of the thermal insulation cotton 207 is glass fiber cotton.

[0034] By installing the sealing sleeve 203 in the inside of the connecting groove 209, and installing the thermal insulation cotton 207 in the inside of the pot part support 101, the overall device can achieve the effect of sealing, and at the same time, the temperature is prevented from spreading to the base.

[0035] As Figure 5 shown, the shape of the limiting block 206 is trapezoidal, and the upper side of the inclined surface of the limiting block 206 is tightly attached to the bottom wall of the fixed plate 201.

[0036] By setting the shape of the limiting block 206 as trapezoidal, the inclined surface of the limiting block 206 can better bear the force, and at the same time, the extension spring 205 can be extruded.

[0037] Working principle: the device is composed of a plurality of heating pipes to form a heating disc 103 for heating the bottom of the electric kettle. In the patent drawings, the heating disc 103 is composed of four-tube composite heating pipes. In practice, it is not limited to four-tube composite, but can also be other multi-tube composite. The resistance wire inside the heating pipe is connected to the power supply, so that the overall heating disc 103 generates heat, thereby realizing heat transfer and heating the bottom of the electric kettle body 1. When the heating disc 103 is assembled and installed, the heating disc 103 is first clamped into the inside of the clamping groove 2, and then the fixed plate 201 is extruded to limit and fix the heating disc 103. The fixed plate 201 is made of aluminum oxide ceramic material, and the surface wall is coated with a coating material made of polytetrafluoroethylene material. The fixed plate 201 can not only withstand high temperature and not conduct heat, but also avoid damage caused by bumps on the surface wall, and at the same time, the overall cost is relatively low. In addition, after the fixed plate 201 fixes the heating disc 103, the limiting block 206 at the lower end is supported and extruded by the elastic force of the extension spring 205, so that the fixed plate 201 can stably fix the heating disc 103. At the same time, the terminal post 202 passes through the inside of the connecting groove 209 to connect with the power line. In addition, the inside is provided with thermal insulation cotton 207 to prevent the inside from being damp and causing damage to the terminal post 202. When the heating disc 103 needs to be replaced, the fixed plate 201 is extruded to the limiting block 206 and the extension spring 205 by holding the handle 208 and pulling the fixed plate 201, so that the inside heating disc 103 can be replaced.

[0038] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
