The generated heat enters the heat exchange chamber 5 along the gas transmission pipe 6 to heat and vaporize the methanol solution in the evaporation chamber 4. Since the heat generated by the heating rods and the combustion of the fuel in the combustion chamber are successively used to heat the methanol in the evaporation chamber, the heating is uniform and the heating efficiency is higher.

One end of an infusion pipe 15 is communicated with the liquid outlet end of the water pump 14, and the other end of the infusion pipe 15 is communicated with the end of the liquid inlet pipe 9 far away from the heat exchange chamber 5.

[0048] The working principle and beneficial effects of the above technical solution are: when it is necessary to input methanol solution into the vaporization chamber 4, the water pump 14 is started, and the water pump 14 pumps the methanol solution in the liquid storage tank 13 into the vaporization chamber 4 through the infusion pipe 15.

[0049] In one embodiment, as Figures 6-7 shown, a stirring and cleaning device is arranged in the liquid storage tank 13. The stirring and cleaning device includes: a motor 23, a first worm 24, a worm gear 16, and a stirring rod 17.

[0050] A motor 23 is provided at the top of the liquid storage tank 13. The output shaft of the motor 23 extends downward into the liquid storage tank 13 and is connected to the top end of a vertically arranged support frame 18. The output shaft of the motor 23 is rotatably connected to the top wall of the liquid storage tank 13. The cross-section of the support frame 18 is diamond-shaped. A first worm 24 in the vertical direction is provided inside the support frame 18. The top end of the first worm 24 is rotatably connected to the inner wall of the top end of the support frame 18. The bottom end of the first worm 24 passes through the bottom wall of the support frame 18 and is connected to the inner wall of the bottom end of the liquid storage tank 13. The first worm 24 is rotatably connected to the bottom wall of the support frame 18;

[0051] A worm gear 16 in the vertical direction is provided inside the liquid storage tank 13. The worm gear 16 meshes with the first worm 24. One end of a transmission shaft 19 passes through the axis of the worm gear 16. The transmission shaft 19 is fixedly connected to the worm gear 16. Connecting rods 20 are respectively provided on both sides of the worm gear 16. One end of each connecting rod 20 is rotatably connected to the transmission shaft 19. The other end of each connecting rod 20 is connected to the support frame 18. Fixed plates 21 are respectively provided at both ends of the transmission shaft 19. A number of stirring rods 17 are arranged at intervals on the outer wall of the circumference of each fixed plate 21. A cleaning brush 22 is provided on the side wall of each stirring rod 17 away from the first worm 24.

[0052] The working principle and beneficial effects of the above technical solution are as follows: After the methanol solution in the liquid storage tank 13 is stored for a period of time, affected by external environmental factors, the methanol solution is unevenly mixed, which affects the use effect of methanol. Start the motor 23 to drive the support frame 18 to rotate, drive the worm gear 16 to rotate around the output shaft of the motor 23, and drive the worm gear 16 to rotate by itself through the worm and worm gear transmission between the worm gear 16 and the first worm 24. Through the compound superposition of movements, the worm gear 16 rotates by itself while rotating around the output shaft of the motor 23, driving the stirring rods 17 to rotate by themselves while rotating around the output shaft of the motor 23, stirring the methanol solution in the liquid storage tank 13 to ensure that the methanol solution is evenly mixed; when the methanol solution is used up, the liquid storage tank 13 needs to be cleaned. Inject cleaning liquid into the liquid storage tank 13, start the motor 23, and the stirring rods 17 stir the cleaning liquid to clean the liquid storage tank 13. The stirring rods 17 drive the cleaning brushes 22 to rotate by themselves while rotating around the output shaft of the motor 23 to clean the inner wall of the liquid storage tank 13, with high cleaning efficiency and good cleaning effect.

[0053] In one embodiment, a heat dissipation port 25 is provided on the bottom wall of the cylinder body 1. An annular filter screen 26 is provided in the heat dissipation port 25. The heat dissipation port 25 communicates with the heat exchange chamber 5.

[0054] The working principle and beneficial effects of the above technical solution are as follows: The heat dissipation port 25 is used to discharge the exhaust gas generated by the combustion of fuel in the combustion chamber 3, and the annular filter screen 26 is used to prevent dust from entering the cylinder body 1.

[0055] In one embodiment, as Figures 8-9 shown, a driving motor 27 is provided on the inner wall of the bottom end of the heat exchange chamber 5. The output shaft of the driving motor 27 passes upward through the axis of the gear 28 and is connected to one end of a connecting frame 29. The cross-section of the connecting frame 29 is V-shaped. The output shaft of the driving motor 27 is rotatably connected to the gear 28. The gear 28 is fixedly connected to the driving motor 27. A second worm 30 is provided in the heat exchange chamber 5. The second worm 30 meshes with the gear 28. The opening end of the connecting frame 29 faces the second worm 30. One end of the second worm 30 is rotatably connected to the second end of the connecting frame 29. The other end of the second worm 30 passes through the third end of the connecting frame 29 and is connected to one end of a rotating rod 31. The second worm 30 is rotatably connected to the third end of the connecting frame 29. A plurality of brush hairs 32 are arranged at intervals on the outer wall of the circumference of the rotating rod 31. The brush hairs 32 are in contact with the annular filter net 26.

[0056] The working principle and beneficial effects of the above technical solution are as follows: After the annular filter net 26 is used for a period of time, a large amount of dust will accumulate, affecting the exhaust gas emission. Start the driving motor 27 to drive the connecting frame 29 to rotate, drive the second worm 30 to rotate around the output shaft of the driving motor 27. Through the gear meshing transmission between the second worm 30 and the gear 28, the second worm 30 rotates self. Through the compound superposition of the movement, the second worm 30 rotates self while rotating around the output shaft of the driving motor 27, driving the brush hairs 32 to rotate self while rotating around the output shaft of the driving motor 27, performing a scanning cleaning on the annular filter net 26. The cleaning ability is strong, and the cleaning speed can be adjusted according to needs. At the same time, the contact area between the brush hairs 32 and the annular filter net 26 is small, so the influence on the exhaust gas emission of the heat dissipation port 25 and the annular filter net 26 is small.

[0057] In one embodiment, as Figures 10-11 shown, it further includes an anti-blocking device. The anti-blocking device includes: a motor 33, a cavity 34, an internal gear 35, and a driving gear 36.

[0058] A cavity 34 is provided below the combustion chamber 3. The cavity 34 is located between the annular vaporization chambers 4. The gas transmission pipe 6 passes through the cavity 34. A first gear 44 is sleeved on the outer wall of the gas transmission pipe 6. The first gear 44 is rotatably connected to the gas transmission pipe 6. An internal gear 35 is provided in the cavity 34. The gas transmission pipe 6 is located at the center of the internal gear 35. The internal gear 35 is arranged on the circumferential inner wall of the cavity 34.

The driving gear 36 meshes with the first gear 44 and the internal gear 35 respectively;

[0059] A motor 33 is arranged below the driving gear 36. The output shaft of the motor 33 passes upward through the axis of the driving gear 36 and is connected to one end of a crank 37. The output shaft of the motor 33 is fixedly connected to the driving gear 36. The air delivery pipe 6 is rotatably connected to one end of a rotating plate 38. The rotating plate 38 is located above the first gear 44. A chute body 39 extending axially is arranged at the bottom end of the rotating plate 38. A first slider 40 is arranged at one end inside the chute body 39, and a second slider 41 is arranged at the other end inside the chute body 39. The first slider 40 and the second slider 41 can reciprocate inside the chute body 39. The bottom end of the first slider 40 is rotatably connected to one end of a first rocker 42, and the bottom end of the second slider 41 is rotatably connected to one end of a second rocker 43. The other end of the first rocker 42 is rotatably connected to the other end of the second rocker 43. The other end of the crank 37 is rotatably connected to the connection part of the first rocker 42 and the second rocker 43.

[0060] The working principle and beneficial effects of the above technical solution are as follows: After the air delivery pipe 6 is used for a period of time, impurities generated by the combustion of fuel in the combustion chamber 3 will accumulate on the inner wall of the air delivery pipe 6, affecting the gas transmission; when the burner is turned off, the untransported methanol vapor will be liquefied when cooled and condense on the inner wall of the vaporization chamber 4, affecting the service life of the vaporization chamber 4; when the motor 33 is started, it drives the driving gear 36 and the crank 37 to rotate. Through the gear meshing transmission between the driving gear 36 and the first gear 44, the first gear 44 is driven to rotate. Through the gear meshing transmission between the driving gear 36 and the internal gear 35, the driving gear 36 rotates around the air delivery pipe 6, driving the rotating plate 38 to rotate around the air delivery pipe 6, driving the first slider 40 and the second slider 41 to rotate around the air delivery pipe 6; the rotation of the crank 37 drives the first rocker 42 and the second rocker 43 to swing back and forth and move left and right along the chute body 39, driving the first slider 40 and the second slider 41 to move left and right along the chute body 39. To sum up, the first slider 40 and the second slider 41 rotate around the air delivery pipe 6 and move left and right along the chute body 39 at the same time, so that the first slider 40 intermittently impacts the air delivery pipe 6, vibrating off the combustion impurities on the inner wall of the air delivery pipe 6, keeping the air delivery pipe 6 clean, so that the second slider 41 intermittently impacts the vaporization chamber 4, vibrating off the methanol water droplets on the inner wall of the vaporization chamber 4, reducing the influence of methanol on the vaporization chamber 4. The first slider 40 and the second slider 41 alternately impact, reducing the influence on the burner; the first rocker 42 and the second rocker 43 swing back and forth and move left and right along the chute body 39 at the same time, increasing the air flow rate in the cavity 34, reducing the temperature of the mechanism, and improving the service life of the device.
