[0038] (III) Beneficial effects

[0039] 1. The far-infrared energy-saving heater cooperates with each other through the servo motor, the rotating shaft, the suction fan, the dustproof net, the brush plate, the sleeve, the second rectangular through hole, the plug rod, the rectangular block and the fixed block, and then the output end of the servo motor rotates to drive the suction fan to rotate and suck air into the interior of the cooling tube, and the dust in the air is blocked by the dustproof net so that it is blocked on the outer surface of the dustproof net, and then the output end of the servo motor rotates synchronously to drive the brush plate to rotate, and then the dust on the outer surface of the dustproof net is cleaned promptly and effectively by the brush on the brush plate, so that the heater can quickly and effectively clean the dust on the dustproof net, with a high degree of automation, thereby reducing the labor intensity of the user and increasing the service life of the heater.

[0040] 2. The far-infrared energy-saving heater, through the setting of the annular dust box and the dust exhaust pipe, allows the dust swept by the brush on the brush plate to fall into the interior of the annular dust box, and by opening the pipe cover on the dust exhaust pipe, the dust collected inside the annular dust box is discharged through the dust exhaust pipe, so that the heater can easily collect the swept dust. At the same time, the annular dust box also acts as a protective cover to prevent dust from spreading into the air, thereby improving the user's working environment and thus improving the practicality of the heater.

[0041] 3. The far-infrared energy-saving heater, due to the setting of the conical spiral heat exchange coil, enables the conical spiral structure to effectively realize the efficient flow of air, reduces the air resistance, increases the contact area between the air and the conical spiral heat exchange coil, thereby increasing the flow of air through the heater, and at the same time facilitates the effective and rapid cooling of the air through the conical spiral heat exchange coil, so that the cooled air enters the heater body, thereby improving the heat dissipation effect of the heater body, and thus improving the working efficiency of the heater body.

[0042] 4. The far-infrared energy-saving heater is provided with a clamping device. By pushing the first ring to slide on the outer surface of the cooling tube toward one end of the annular dust collecting box, after a series of transmissions, the three limit blocks will no longer block the insertion rod, and the insertion rod can be pulled out of the circular groove through the fixed block, and the dustproof net and the sleeve will slide out from the outer surface of the insertion rod, and the dustproof net can be pulled out from the cooling tube to complete the disassembly of the dustproof net, which is convenient for effective cleaning of dust on the dustproof net with clean water, thereby improving the usability of the dustproof net, and at the same time, the brush plate can be slid from the outer surface of the rectangular block and the insertion rod to complete the disassembly of the brush plate, thereby facilitating the replacement of the brush plate, thereby making it convenient for the heater to simultaneously disassemble the dustproof net and the brush plate, and at the same time improving the disassembly efficiency.

[0043] 5. The far-infrared energy-saving heater has an arc surface at one end of the insertion rod away from the rectangular block, so that when the dust net and the brush plate are installed, the end of the insertion rod away from the rectangular block can be inserted into the inside of the circular groove more smoothly, thereby improving the work efficiency of the heater in synchronously installing the dust net and the brush plate.

[0044] 6. The far-infrared energy-saving heater has an inclined surface on the side of the limit block that is away from the inner bottom end of the circular groove and is away from the first compression spring. This makes it easier to push the inclined end of the limit block into the rectangular slide groove through the insertion rod, thereby further improving the work efficiency of the heater in synchronously installing the dust screen and the brush plate.

[0045] 7. Due to the setting of the telescopic guard plate, the far-infrared energy-saving heater can effectively prevent air from entering the interior of the cooling tube through the first rectangular through hole without being filtered by the dustproof net, thereby affecting the heat dissipation of the heater body, thereby improving the sealing of the interior of the cooling tube, thereby improving the practicality and stability of the heater.

[0093] Furthermore, since the end of the limit block 29 away from the first compression spring 28 is inclined on one side of the inner bottom end of the circular groove 23, it is more convenient to push the inclined end of the limit block 29 to smoothly retract into the interior of the rectangular slide groove 26 through the insertion rod 33, thereby further improving the working efficiency of the heater for synchronous installation of the dust screen 7 and the brush plate 8.

[0094] Furthermore, due to the provision of the telescopic guard plate 38, it can effectively prevent air from entering the interior of the cooling tube 2 through the first rectangular through hole 21 without being filtered by the dustproof net 7, thereby affecting the heat dissipation of the heater body 1, thereby improving the sealing of the interior of the cooling tube 2, thereby improving the practicality and stability of the heater.

[0101] Furthermore, since the end of the rod 33 away from the rectangular block 36 is set as an arc surface, when the dust screen 7 and the brush plate 8 are installed, the end of the rod 33 away from the rectangular block 36 can be inserted into the interior of the circular groove 23 more smoothly, thereby improving the working efficiency of the heater for synchronously installing the dust screen 7 and the brush plate 8.

At the same time, the annular dust box 4 also acts as a protective cover to prevent dust from diffusing into the air, thereby improving the working environment of the user, thereby improving the practicality of the heater.
