The detection end of the thermostat is located inside the heat-conducting inner liner and the heat-conducting column. The current output end of the thermostat is electrically connected to the current input ends of the first and second heating wires via a power cord.

[0011] Specifically, the inner wall of the barrel is provided with a heat insulation layer, which is made of rock wool fiber material.

[0012] Specifically, both the heat-conducting inner liner and the heat-conducting column are made of graphene material.

[0013] The beneficial effects of this utility model are:

[0014] The present invention discloses a high-efficiency heater in which a coil is disposed inside a heat-conducting inner liner through an arc-shaped groove, allowing the inner liner to fully contact the coil and heat the medium inside the coil from the outside.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Installing a coil inside the heat-conducting inner tank increases the flow time of the medium within the tank, thus ensuring thorough heating and high efficiency. Figure 1-3As shown, the present invention provides a high-efficiency heater, which includes a barrel body 1, a heat-conducting inner liner 2 inside the barrel body 1, first electric heating wires 5 are equidistantly embedded inside the heat-conducting inner liner 2, and an arc-shaped groove 7 is formed inside the heat-conducting inner liner 2 between the first electric heating wires 5, and a coil 8 is arranged inside the arc-shaped groove 7.

[0022] The inner bottom of the heat-conducting inner liner 2, located inside the coil 8, is fixed with a heat-conducting column 4 by bolts. Inside the heat-conducting column 4, a second electric heating wire 6 is fixed at equal intervals by bolts.

[0023] In use, the first electric heating wire 5 heats the heat-conducting inner liner 2, and the second electric heating wire 6 heats the heat-conducting column 4. The heat-conducting inner liner 2 heats the internal medium from the outside of the coil 8, and the heat-conducting column 4 heats the internal medium from the inside of the coil 8.

[0024] For example, such as Figure 3 As shown, the present invention also includes a bucket cover 12 fixed to the top of the bucket body 1 by bolts, a protective sleeve 13 welded to the top of the bucket cover 12, and a flange 9 welded to the water inlet end of the coil 8 located at the top of the protective sleeve 13.

[0025] When in use, open the lid 12 to remove the heat-conducting column 4 and remove the coil 8 for easy replacement. The flange 9 facilitates the connection of the water inlet of the coil 8 to external equipment.

[0026] For example, such as Figure 3 As shown, the present invention also includes a valve 10 connected to the water outlet end of the coil 8 located outside the barrel 1 via a threaded groove, and a thermometer 11 connected to the top of the water outlet end of the coil 8 via a threaded groove.

[0027] When in use, valve 10 is opened to allow the medium in coil 8 to flow out, and thermometer 11 is used to detect the temperature of the medium flowing out of coil 8.

[0028] For example, such as Figure 1 As shown, the present invention also includes a thermostat 14 mounted on one side of the barrel 1 via a mounting base. The detection end of the thermostat 14 is located inside the heat-conducting inner liner 2 and the heat-conducting column 4. The current output end of the thermostat 14 is electrically connected to the current input end of the first heating wire 5 and the second heating wire 6 via a power cord.

[0029] In use, the thermostat 14 is used to control the heating of the first electric heating wire 5 and the second electric heating wire 6 and their heating temperature.

[0030] For example, such as Figure 2 As shown, the present invention also includes a heat insulation layer 3 provided on the inner wall of the barrel 1, the heat insulation layer 3 being made of rock wool fiber material.

[0031] When in use, the insulation layer 3 made of rock wool fiber material can reduce the loss of heat inside the barrel 1.

[0032] For example, such as Figure 2 As shown, this utility model also includes the fact that both the heat-conducting inner liner 2 and the heat-conducting column 4 are made of graphene material.

[0033] When in use, the heat-conducting inner liner 2 and heat-conducting column 4, made of graphene material, have good thermal conductivity.

[0034] When in use, the device is connected to an external power source using a power cord. The medium flows into the coil 8 through the water inlet and is then discharged through the open valve 10. The first heating wire 5 and the second heating wire 6 are heated by the thermostat 14.

[0035] The first electric heating wire 5 heats the heat-conducting inner liner 2, and the second electric heating wire 6 heats the heat-conducting column 4. The heat from the heat-conducting inner liner 2 and the heat-conducting column 4 is conducted to the coil 8, which heats the medium flowing in the coil 8. The coil 8 can increase the time the medium flows in the heat-conducting inner liner 2, so that the medium can be fully heated and the heating efficiency is high.

[0036] The coil 8 is installed inside the heat-conducting inner liner 2 through the arc groove 7, so that the heat-conducting inner liner 2 can fully contact the coil 8 and heat the medium inside the coil 8 from the outside. The coil 8 is sleeved on the outside of the heat-conducting column 4, and the heated heat-conducting column 4 heats the medium inside the coil 8 from the inside.

[0037] The heat insulation layer 3 serves as a heat insulation layer, which can reduce the heat conducted from the heat-conducting inner liner 2 to the barrel 1. The temperature gauge 11 is set to detect and display the temperature of the medium flowing out of the coil 8, so that the descaling agent and other substances can circulate in the coil 8 before being discharged, which can clean the inside of the coil 8.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
