[0042] (3) Beneficial effects

[0043] 1. This far-infrared energy-saving heater adopts advanced far-infrared radiation technology through the mutual cooperation between the quartz heating tube, resistance wire and ceramic sealing accessories at the outlet end. By directly converting electrical energy into far-infrared radiation energy, it can achieve rapid and uniform heating of the heated object. This heating method not only significantly improves energy utilization efficiency, reduces heat energy loss, reduces costs, is more environmentally friendly and energy-saving, but also achieves high-precision control of temperature, thereby ensuring the stability and reliability of the heating process.

[0044] 2. Due to the arrangement of the first main thermal insulation board and the second main thermal insulation board, the far-infrared energy-saving heater can effectively reduce the heat dissipated to the outside when the heater is working, so that more heat is concentrated on the heated object, thereby improving the heating efficiency.

[0045] 3. Due to the mutual cooperation between the first secondary thermal insulation board, the first reinforced thermal insulation board, the second secondary thermal insulation board and the second reinforced thermal insulation board, the far-infrared energy-saving heater is convenient for fixing the quartz heating tubes on the first main thermal insulation board and the second main thermal insulation board, and also plays a role of heat insulation, protection and buffering. Through its excellent thermal insulation performance, most of the heat energy is retained inside the heater and on the heated object, thereby improving the heating efficiency, reducing energy consumption and ensuring the efficient, safe and stable operation of the heater. Through its excellent protective effect, the internal components of the heater are protected from direct damage by high temperature. In a high-temperature working environment, the internal components may age, deform or fail due to long-term heat exposure. The thermal insulation board acts as a barrier to effectively isolate the high temperature, thereby extending the service life of the far-infrared energy-saving heater.

[0046] 4. This far-infrared energy-saving heater can convert electrical energy into thermal energy more directly and effectively and reduce the loss of thermal energy. Therefore, it can significantly reduce energy consumption in practical applications. Compared with traditional heating methods, far-infrared heaters can usually save about 20% of electricity, further reducing energy consumption.

[0047] 5. The far-infrared energy-saving heater and the thermal insulation board are made of ceramic fiber material. Ceramic fiber has excellent properties such as high temperature resistance, oxidation resistance, chemical corrosion resistance and low thermal conductivity. It can not only effectively isolate heat transfer, but also maintain stable performance in high temperature environment, further extending the service life of the far-infrared energy-saving heater.

[0048] 6. Due to the arrangement of the hook seat and the double spring buckle, the far-infrared energy-saving heater is quicker and more convenient to install, reduces labor and is easier to manufacture.

[0049] 7. The far-infrared energy-saving heater adopts a modular combination through the arrangement of two first heater shells and two second heater shells, has a compact structure, and is easy to install. At the same time, its manufacturing process is also relatively simple, thereby reducing manufacturing costs.

[0050] 8. Due to the provision of the cross-shaped screw, the far-infrared energy-saving heater facilitates quick installation or disassembly of the wiring installation box, thereby facilitating quick connection of the first connecting wire and the second connecting wire to the ceramic wiring seat. At the same time, the wiring installation box also protects the ceramic wiring seat, thereby improving the practicality of the far-infrared energy-saving heater.

[0051] 9. The far-infrared energy-saving heater and the quartz heating tube use infrared radiation to directly transfer heat to the object to be heated without passing through the air medium, thereby avoiding the generation of harmful gases and effectively solving environmental problems.

[0126] In this embodiment, due to the arrangement of the hook seat 5 and the double spring buckle 6, the far-infrared energy-saving heater can be installed more quickly and conveniently, with reduced labor and simple manufacturing.

[0127] Furthermore, due to the arrangement of the first main thermal insulation board 14 and the second main thermal insulation board 18, the far-infrared energy-saving heater can effectively reduce the heat dissipated to the outside when the heater is working, so that more heat is concentrated on the heated object, thereby improving the heating efficiency.

[0128] Furthermore, since the far-infrared heater can convert electrical energy into thermal energy more directly and efficiently and reduce the loss of thermal energy, it can significantly reduce energy consumption in actual applications. Compared with traditional heating methods, the far-infrared heater can usually save about 20% of electricity, further reducing energy consumption.

[0129] Furthermore, the materials of the first main thermal insulation board 14, the second main thermal insulation board 18, the first auxiliary thermal insulation board 27, the second auxiliary thermal insulation board 30, the first reinforced thermal insulation board 28 and the second reinforced thermal insulation board 29 in the present invention are all ceramic fiber materials. Ceramic fiber, with its excellent high temperature resistance, oxidation resistance, chemical corrosion resistance and low thermal conductivity, can not only effectively isolate heat transfer, but also maintain stable performance in high temperature environment, further extending the service life of the far-infrared energy-saving heater.

[0130] Furthermore, the quartz heating tube 4 uses infrared radiation to directly transfer heat to the object to be heated without passing through the air medium, thereby avoiding the generation of harmful gases and effectively solving the environmental protection problem.

[0131] Furthermore, the thickness of the first reinforcement heat insulation board 28 and the second reinforcement heat insulation board 29 in the present invention is about 5 mm.

[0132] Working principle: When using the far-infrared energy-saving heater, the two L-shaped heater shells are fixedly connected through the hook seat 5 and the double spring buckle 6, so that the two L-shaped heater shells form a square tube that wraps the heated object, and then the neutral wires and live wires of the two first connecting wires 22 and the two second connecting wires 23 are fixed to the corresponding wiring points on the ceramic wiring seat 13 through the wiring fixing hexagon socket screws 35, and then the wiring installation box 3 is detachably fixed to the left first heater shell 1 by the cross screw 11 to protect the ceramic wiring seat 13, thereby completing the installation of the far-infrared energy-saving heater;

[0133] Furthermore, by providing the quartz heating tube 4, the resistance wire 24 and the ceramic plugging fitting 25 at the outlet end, the far-infrared electric heater adopts advanced far-infrared radiation technology, and directly converts electrical energy into far-infrared radiation energy to achieve rapid and uniform heating of the heated object. This heating method not only significantly improves energy utilization efficiency, reduces heat energy loss, reduces costs, is more environmentally friendly and energy-saving, but also achieves high-precision control of temperature, thereby ensuring the stability and reliability of the heating process;

[0134] Furthermore, due to the arrangement of the first main heat insulation board 14 and the second main heat insulation board 18, the far-infrared energy-saving heater can effectively reduce the heat dissipated to the outside when the heater is working, so that more heat is concentrated on the heated object, thereby improving the heating efficiency;

[0135] Furthermore, due to the mutual cooperation between the first auxiliary thermal insulation board 27, the first reinforced thermal insulation board 28, the second auxiliary thermal insulation board 30 and the second reinforced thermal insulation board 29, the far-infrared energy-saving heater is convenient for fixing the quartz heating tube 4 on the first main thermal insulation board 14 and the second main thermal insulation board 18, and also plays a role of heat insulation, protection and buffering. Through its excellent thermal insulation performance, most of the heat energy is retained inside the heater and on the heated object, thereby improving the heating efficiency, reducing energy consumption and ensuring the efficient, safe and stable operation of the heater. Through its excellent protective effect, the internal components of the heater are protected from direct damage by high temperature. In a high-temperature working environment, the internal components may age, deform or fail due to long-term heat exposure. The thermal insulation board acts as a barrier to effectively isolate the high temperature, thereby extending the service life of the far-infrared energy-saving heater.

[0136] Furthermore, since the far-infrared heater can convert electrical energy into heat energy more directly and efficiently and reduce heat loss, it can significantly reduce energy consumption in practical applications. Compared with traditional heating methods, the far-infrared heater can usually save about 20% of electricity, further reducing energy consumption.

[0137] Furthermore, by providing two first heater housings 1 and two second heater housings 2, the far-infrared energy-saving heater adopts a modular combination, has a compact structure, and is easy to install. At the same time, its manufacturing process is relatively simple, which reduces the manufacturing cost.

[0138] Furthermore, due to the arrangement of the hook seat 5 and the double spring buckle 6, the far-infrared energy-saving heater can be installed more quickly and conveniently, reduces labor, and is easy to manufacture.

[0139] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
