Specific embodiments
[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0024] Embodiment 1, refer to Figures 1-4 , a coal-to-electricity environmental protection heater, including a fixed base 1, a cylinder 2 and a mounting box 3. A fan 5 is installed at the rear end of the fixed base 1, an air outlet 6 is installed at the front end of the fixed base 1, a rotatable fan 7 is installed inside the air outlet 6, the rear end of the fan 7 is connected to a heating pipe 17, a rotatable rotating rod 10 is installed inside the fixed base 1, both ends of the rotating rod 10 are respectively connected to a first sprocket 9 and a second sprocket 11, a first chain 8 is simultaneously engaged on the outer walls of the first sprocket 9 and the fourth sprocket 16, a dust-proof net 15 is installed inside the fan 5, a rotatable third sprocket 13 is installed at the rear end of the fan 5, a second chain 12 is simultaneously engaged on the outer walls of the third sprocket 13 and the second sprocket 11, and a cleaning brush plate 14 is installed on the top surface of the third sprocket 13.
[0025] Furthermore, refer to Figure 2 , a brush is fixedly installed on the outer wall of the side of the cleaning brush plate 14 close to the dust-proof net 15. The brush is attached to the outer wall of the dust-proof net 15 in the initial state. By setting the cleaning brush plate 14 and fixedly installing a brush on the outer wall of the side of the cleaning brush plate 14 close to the dust-proof net 15, the cleaning brush plate 14 can clean the sundries on the outer wall of the dust-proof net 15 after being driven by the third sprocket 13 to rotate.
[0026] In addition, a bearing is provided between the rotating rod 10 and the fixed base 1. By providing a bearing between the rotating rod 10 and the fixed base 1, the rotation of the rotating rod 10 does not require too much force to drive.
[0027] During specific implementation, during the use of the device, the fan 5 will start to send external air into the interior of the cylinder body 2 and discharge it from the air outlet 6. During the process of discharging the air flow, the fan 7 rotatably installed inside the air outlet 6 will be driven to rotate by the high-speed air flow. After the fan 7 rotates, the fourth sprocket 16 connected to the rear side of the fan 7 will rotate synchronously. The outer walls of the fourth sprocket 16 and the first sprocket 9 are simultaneously engaged with the first chain 8. Therefore, the first sprocket 9 will also be driven to rotate. Since the first sprocket 9 is fixedly installed on one side of the rotating rod 10, the rotating rod 10 and the second sprocket 11 will also start to rotate. After the second sprocket 11 rotates, the second chain 12 engaged on the outer wall of the second sprocket 11 will drive the third sprocket 13 to rotate. The cleaning brush plate 14 is fixedly installed on the top surface of the third sprocket 13. Therefore, the final achieved effect is that after the fan 5 starts, the cleaning brush plate 14 is driven to rotate by multiple transmission parts, and the outer wall of the dust-proof net 15 is directly cleaned by the brush installed on the outer wall to prevent the dust-proof net 15 from being blocked by sundries.
[0028] By setting the air outlet 6 and the cleaning brush plate 14 and arranging multiple transmission components between the two, the device can utilize the wind power generated by the device to clean the dust-proof net 15, preventing the dust-proof net 15 from being blocked by sundries, enabling the device to continue to be used normally, and also increasing the service life of the device.
[0029] Embodiment 2, on the basis of Embodiment 1, please refer to Figures 1-4 , a coal-to-electricity environmental protection heater, wherein, a wire plug 4 is installed on one side of the installation box 3, a cavity is opened inside the fixed base 1, an inner partition 18 is fixedly installed in the cavity opened inside the fixed base 1 for the inner cylinder body 2. The specific number of the inner partitions 18 is two, and the two inner partitions 18 are symmetrically arranged. A wind channel is formed between the inner partition 18 and the inner wall of the fixed base 1. Ventilation holes 19 are opened on the inner wall of the inner partition 18. Two groups of ventilation holes 19 are opened on the inner wall of one inner partition 18, and the two groups of ventilation holes 19 are symmetrically arranged. A plurality of heating tubes 17 are arranged inside the fixed base 1.
[0030] Further, refer to Figure 4 , the edge position of the inner partition 18 is inclined, and the ventilation holes 19 are opened through the outer wall at the inclined part of the inner partition 18. By setting the edge position of the inner partition 18 to be inclined and arranging the ventilation holes 19 to be opened through the outer wall at the inclined part of the inner partition 18, more hot air can enter through the ventilation holes 19.
[0031] During specific implementation, after the fan 5 and the heating pipe 17 are started simultaneously, the cooperation between them can generate hot air. During their use, the fan 5 blows air into the interior of the cylinder body 2, which is heated by the heating pipe 17 and finally flows out from the air outlet 6. Before the hot air flows into the air outlet 6, some of the hot air blows into the ventilation holes 19 and flows between the inner partition plate 18 and the inner wall of the fixed base 1, and finally flows out from the ventilation holes 19 opened on the other side of the inner partition plate 18 and mixes with the newly entered air to assist in heating the new air, making the heating function of the device better without changing the power consumption.
[0032] By arranging an inner partition plate 18 in the fixed base 1 and providing ventilation holes 19 on the outer wall of the inner partition plate 18, part of the hot air generated in the device can circulate in the fresh air to assist in heating the fresh air, increasing the heating effect of the device without changing the power consumption.
[0033] In addition, a wiring seat is installed inside the installation box 3, and the heating pipe 17 is mainly powered by the commercial power supply.
[0034] Working principle: During the use of the device, the fan 5 is started to send external air into the interior of the cylinder body 2 and vent it from the air outlet 6. During the process of venting the air flow, the fan 7 rotatably installed inside the air outlet 6 will be driven to rotate by the high-speed air flow. After the fan 7 rotates, the fourth sprocket 16 connected to the rear side of the fan 7 rotates synchronously. The outer walls of the fourth sprocket 16 and the first sprocket 9 are simultaneously engaged with the first chain 8, so the first sprocket 9 will also be driven to rotate. Since the first sprocket 9 is fixedly installed on one side of the rotating rod 10, the rotating rod 10 and the second sprocket 11 will also start to rotate. After the second sprocket 11 rotates, the second chain 12 engaged with the outer wall of the second sprocket 11 will drive the third sprocket 13 to rotate. The cleaning brush plate 14 is fixedly installed on the top surface of the third sprocket 13. Therefore, the final achieved effect is that after the fan 5 is started, the cleaning brush plate 14 is driven to rotate by multiple transmission parts, and the outer wall of the dust-proof net 15 is directly cleaned by the brush installed on the outer wall to prevent the dust-proof net 15 from being blocked by sundries.
[0035] After the fan 5 and the heating pipe 17 are started simultaneously, the cooperation between them can generate hot air. During their use, the fan 5 blows air into the interior of the cylinder body 2, which is heated by the heating pipe 17 and finally flows out from the air outlet 6. Before the hot air flows into the air outlet 6, some of the hot air blows into the ventilation holes 19 and flows between the inner partition plate 18 and the inner wall of the fixed base 1, and finally flows out from the ventilation holes 19 opened on the other side of the inner partition plate 18 and mixes with the newly entered air to assist in heating the new air, making the heating function of the device better without changing the power consumption.
[0036] By setting the air outlet 6 and the cleaning brush plate 14, and arranging a plurality of transmission components between the two, the device can utilize the wind power generated by the device to clean the dust-proof net 15, preventing the dust-proof net 15 from being blocked by sundries, enabling the device to continue to be used normally, and also increasing the service life of the device.
[0037] By arranging an inner partition 18 inside the fixed base 1 and providing ventilation holes 19 on the outer wall of the inner partition 18, part of the hot air generated in the device can be circulated in the fresh air to assist in heating the fresh air, increasing the heating effect of the device without changing the power consumption.
