[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention adopts a designed heating mechanism, generates hot air through a hot air circulation fan and blows it out through multiple groups of air outlets on the air outlet duct to heat the glass surface, so that the glass can be heated evenly. The blown hot air circulates in the upper box and the lower box, thereby increasing the heating speed of the glass at the same power, reducing and saving energy consumption, and achieving high efficiency and energy saving. Moreover, when the inside of the air outlet is clogged by dust or foreign matter after long-term use, the inside of the air outlet is cleaned by a rotating brush that moves and rotates in the left and right directions, so that the air outlet remains unobstructed and the stability of the subsequent heating effect on the glass is maintained.

[0016] (2) The present invention is designed with a blowing member.

[0023] The present invention adopts a designed heating mechanism, generates hot air through a hot air circulation fan 200 and blows it out through multiple groups of air outlets 205 on the air outlet duct 201 to heat the glass surface, so that the glass can be heated evenly, and the blown hot air circulates in the upper box 100 and the lower box 101, thereby increasing the heating speed of the glass under the same power, reducing and saving energy consumption, and achieving high efficiency and energy saving. Moreover, when dust or foreign matter adheres to the inside of the air outlet 205 and causes blockage after long-term use, the inside of the air outlet 205 is cleaned by a rotating brush 217 that moves and rotates in the left and right directions, so that the air outlet 205 remains unobstructed, thereby maintaining the stability of the subsequent heating effect on the glass.

[0024] During use, when some dust and foreign matter adhere to the inside of the air outlet 205, the drive motor 211 is turned on first. At this time, the drive motor 211 is started, and the working end drives the lower transmission wheel to rotate, driving the upper transmission wheel and the screw rod 208 to rotate. At this time, the rotating screw rod 208 will drive the multiple sets of second bevel gears 210 to rotate, and then drive the first bevel gear 209 to rotate, and then the first bevel gear 209 and the rotating rod 214 rotate, and the rotating rod 214 can drive the arc baffle 218 and the arc rubber 219 to rotate, and then The arc-shaped rubber 219 can cover the inner wall of the air outlet 205, preventing the dust and foreign matter from easily entering the interior of the air outlet 201 when the subsequent rotating brush 217 cleans the dust and foreign matter in the air outlet 205. When the high-pressure gas is blown into the air outlet 205 through the nozzle 401, it is also convenient to blow the dust and foreign matter outward. At this time, the electric slide rail 203 is turned on, and the slider 226 on the electric slide rail 203 moves toward the front direction of the air outlet 201, driving the moving plate 206 to move, and the moving plate 206 brings The multiple groups of vertical columns 221 and the vertical rods 215 move with the vertical column 221. During the movement, the meshing action between the lower toothed ring 225 and the rack 224 at the bottom of the vertical column 221 can drive the lower toothed ring 225 to rotate, thereby driving the vertical column 221 and the upper toothed ring 222 to rotate. Then, the upper toothed ring 222 drives the double-sided toothed belt 204 to rotate, and the double-sided toothed belt 204 drives the upper gear 213 to rotate, thereby driving the vertical rod 215 and the rotating brush 217 to rotate. The moving and rotating rotating brush 217 cleans the dust and dirt attached to the inside of the air outlet 205. Foreign objects are cleaned. When the slider 226 moves to a suitable position toward the front of the device, the slider 226 on the electric slide rail 203 moves toward the back of the device, thereby driving the rotating brush 217 to move toward the back of the device. This reciprocating process can clean the dust and foreign objects inside the air outlet 205. After cleaning, the reverse principle is used to move the rotating brush 217, the movable plate and other structures 206 to their original positions, and the arc baffle 218 and the arc rubber 219 are rotated to their original positions.

[0025] Embodiment 3 Based on Example 2, please refer to Figure 8-Figure 15, a purge member is provided on the movable plate 206, and the purge member includes a hollow tube rack 402 arranged above the movable plate 206 and a plurality of nozzles 401 fixedly arranged on the front of the hollow tube rack 402, the nozzles 401, the hollow tube rack 402 and the inlet pipe 400 are connected, and the nozzles 401 can spray high-pressure gas downward to blow out the dust and foreign matter in the air outlet 205, and the two ends of the hollow tube rack 402 are fixedly provided with sliding plates 407, and the top of the movable plate 206 is fixedly provided with two groups of round-shaped blocks 406, and the ends of the sliding plates 407 pass through the inside of the round-shaped blocks 406, and the top of the movable plate 206 is fixedly provided with an inlet pipe 400, and a fixed valve is installed at the position between the inlet pipe 400 and the hollow tube rack 402 below; A long baffle 409 is fixedly provided on the top of the sliding plate 407, and short baffles 408 are fixedly provided on the tops of both ends of the hollow pipe frame 402, and a connecting spring 405 is fixedly provided between the long baffle 409 and the short baffle 408; A protruding column 404 is fixedly provided on the outside of the vertical column 221, and a groove 403 is opened inside the hollow pipe frame 402. After the protruding column 404 penetrates into the groove 403, it can drive the hollow pipe frame 402 to move, and then drive the nozzle 401 to move. The end of the protruding column 404 penetrates into the groove 403.

[0026] The present invention is designed with a blowing piece. When in use, the rotating brush 217 sweeps the dust and foreign matter in the air outlet 205 and then blows out high-pressure gas through the nozzle 401. In addition, when the nozzle 401 is blowing the dust and foreign matter in the lower air outlet 205, the protruding column 404 is driven to rotate by following the rotation of the vertical column 221 and penetrate into the groove 403, thereby driving the hollow pipe frame 402 to move back and forth in the front and rear directions of the equipment, and then driving the nozzle 401 to move back and forth. The movement of the nozzle 401 increases the effect of blowing out the dust and foreign matter in the air outlet 205 at different positions below, thereby improving the cleaning effect.

[0027] During use, the high-pressure gas pipe 300 is installed at the inlet pipe 400. When the movable plate 206 moves and drives the rotating brush 217 to rotate to clean the dust and foreign matter at the lower air outlet 205, the high-pressure gas entering from the inlet pipe 400 enters the nozzle 401 through the hollow pipe frame 402, and then the nozzle 401 blows the high-pressure gas into the lower air outlet 205, and blows out the dust and foreign matter swept by the rotating brush 217. At the same time, the protruding column 404 is driven to rotate and penetrate into the groove 403 by the rotating vertical column 221, and then the hollow pipe frame 402 is moved toward the front or back direction of the air outlet 201, driving the sliding plate 407 and the long baffle 409 move, and at this time, the two groups of connecting springs 405 are stretched or compressed respectively. Subsequently, when the raised column 404 rotates and leaves the inside of the groove 403, it is reset under the stretching or compression of the connecting spring 405, driving the hollow pipe frame 402 and the sliding plate 407 to move to the original position. When the raised column 404 rotates one circle and penetrates into the inside of the groove 403 again, it can drive the hollow pipe frame 402, the sliding plate 407, etc. to move again. When the hollow pipe frame 402 moves, it will drive the nozzle 401 to move with it, thereby increasing the effect of the nozzle 401 on blowing dust and foreign matter inside the air outlet 205 at different positions on the lower air outlet duct 201.

[0028] Embodiment 4 Based on Example 3, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 An outlet pipe 301 is embedded inside the inner ring 216, an air pipe 300 is fixedly installed on the top of the outlet pipe 301, an extension pipe is fixedly installed on the inlet pipe 400, a connecting hose 302 is fixedly installed between the end of the extension pipe and the air pipe 300, and the extension pipe is connected to the air pipe 300 below through the connecting hose 302 when the hollow pipe rack 402 moves back and forth, and an opening and closing valve 303 is installed on the outside of the extension pipe.

[0029] The present invention combines the designed outlet pipe 301, air pipe 300, extension pipe, connecting hose 302 and opening and closing valve 303. During use, after the dust and foreign matter blocked in the air outlet 205 are cleaned, the installation valve located below the air outlet duct 201 and between the fixing box 202 is closed, and the opening and closing valve 303 is opened. High-pressure wind is blown into the interior of the air outlet duct 201 through the outlet pipe 301, so that some dust and foreign matter that enter the interior of the air outlet duct 201 from the air outlet 205 during use can be blown out from the air outlet 205, thereby reducing the impact of hot air mixed with dust and foreign matter in the air outlet duct 201 and adhering to the glass surface after being blown toward the glass from the air outlet 205 in subsequent use, thereby improving the heating quality of the glass.

[0030] During use, after the dust and foreign matter attached to the air outlet 205 are cleaned, the installation valve located between the bottom of the air outlet duct 201 and the fixed box 202 is closed, the fixed valve located between the extension pipe and the hollow pipe rack 402 is closed, and then the opening and closing valve 303 located on the extension pipe is opened. At this time, the high-pressure gas entering the inlet pipe 400 enters the air pipe 300 through the connecting hose 302, and then the high-pressure gas enters the outlet pipe 301 and is blown out to the inside of the air outlet duct 201 through the outlet pipe 301. Some dust and foreign matter that entered the inside of the air outlet duct 201 from the air outlet 205 during the previous use process are blown out from the air outlet 205 along with the high-pressure gas, thereby reducing the impact of the hot air mixed with dust and foreign matter inside the air outlet duct 201 mixed with dust and foreign matter that is blown to the glass from the air outlet 205 to the glass and adheres to the glass surface in subsequent use, thereby improving the heating quality of the glass.
