Description

TECHNICAL FIELD

[0001] The present disclosure belongs to the technical field of automobile accessories, and particularly relates to a self-dedusting multi-ignition-point co-heating fuel heater.BACKGROUND

[0002] The fuel heater is a small heating device that releases a large amount of combustion heat by burning liquid fuels such as diesel, gasoline, natural gas, and bio-oils currently available in the market. The mechanical structure of the fuel heater separates these fuels and utilizes the material density of the mechanism to form an oil film. This oil film is then mixed and atomized with combustion-supporting air before being ignited by the ignition component. The structure of the fuel heater and its connections include a motor, a combustion-supporting fan, an oil delivery device, a volatilization mesh, an ignition plug, a combustion chamber, and a heat exchanger.

[0003] Currently, the market for fuel heaters both domestically and internationally offers a diverse range of products with similar structures and performance. Market application surveys and customer feedback have revealed the following issues: The environments in which heaters are currently used are limited. In coal mines, mining sites, and dusty environments, both domestic and international heaters experience problems such as failure to ignite and burn or low combustion efficiency. Additionally, the lifespan of the heater's motor is significantly reduced, noise levels increase, and emission components do not meet environmental standards. The combustion chamber accumulates severe carbon deposits, and issues such as burnout and deformation occur, causing the heater to lose its primary function.

[0004] Therefore, there is a need for a fuel heater that can address the aforementioned problems.SUMMARY

[0005] In view of the aforementioned problems, the present disclosure provides a self-dedusting multi-ignition-point co-heating fuel heater, which aims to solve the problems associated with the heater's ignition function failure and flame interruption during combustion in dusty environments, as well as to mitigate the accumulation of carbon deposits within the combustion chamber and enhance the low heat conversion efficiency of the fuel.

[0006] In order to achieve the above object, the technical solution adopted by the present disclosure is: a self-dedusting multi-ignition-point co-heating fuel heater, comprising a combustion chamber, wherein an outer side surface of the combustion chamber is provided with a plurality of first air inlets penetrating inside and outside; an ignition disk is fixedly arranged at an end, close to an air inlet end, of the combustion chamber, a volatilization chamber is arranged in the ignition disk, a feeding pipe is connected to one side of the volatilization chamber, and an igniter is further arranged in the ignition disk; and an end face of the ignition disk is provided with a plurality of second air inlets communicating with an inner portion of the combustion chamber, the plurality of second air inlets are arranged in a circumferential array around the volatilization chamber, an air inlet side of the ignition disk is movably provided with a movable pin that is capable of inserting into one of the plurality of second air inlets, thereby cleaning one of the plurality of second air inlets, and the movable pin is connected to a driving assembly for driving the movable pin to move.

[0007] Compared with the prior art, the beneficial effects of the present disclosure are as follows: By arranging a plurality second air inlets, air can enter the combustion chamber from multiple points, thereby dispersing the air intake. This allows for ignition and combustion even in dusty environments or environments with severely polluted air quality, reducing the probability of single-cavity flameout. One of the plurality of movable pins that is arranged can clean the hole wall of one of the plurality of second air inlets. When dust blocks one of the plurality of second air inlets, the penetration of one of the plurality of movable pins ensures that one of the plurality of second air inlets remain unblocked for air intake. The heater can still ensure the volatility density of the fuel and its proper mixing with air in dusty environments, as well as reduce the impact of dust-laden air on combustion and the formation of carbon deposits. With normal use, there will be no flameout.

[0008] As a further improvement of the above solution, an outer end face of the ignition disk is provided with a guide piece protruding outwards, a push head capable of jacking the movable pin is slidably arranged on the guide piece, a main shaft is in threaded connection with the push head, and the main shaft is in power connection with the driving assembly.

[0009] As a further improvement of the above solution, a plurality of movable pins are arranged, a connecting plate is arranged between the plurality of movable pins, the connecting plate and the ignition disk are arranged in a sliding mode, a spring is arranged between the connecting plate and the ignition disk, and the spring abuts against the connecting plate, so that one of the plurality of movable pins slides out of one of the plurality of second air inlets.

[0010] The technical effect of the aforementioned improvement is as follows: By arranging a push head, it can be driven to move towards one side of the connecting plate when the main shaft rotates. After contact with the connecting plate, the push head will push the connecting plate and one of the plurality of movable pins to move synchronously, so that one of the plurality of movable pins enters one of the plurality of second air inlets and cleans it thoroughly, facilitating normal combustion within the combustion chamber. The arranged spring exerts a reverse pushing force on the connecting plate, which can push one of the plurality of movable pins to extend outward from one of the plurality of second air inlets when the push head moves in the reverse direction and loses its pushing force on the connecting plate, allowing one of the plurality of second air inlets to intake air.

[0011] As a further improvement of the above solution, an outer side of the combustion chamber is rotatably sleeved with a first ferrule, the first ferrule is provided with a plurality of first extension rods extending in its axial direction, one of the plurality of first extension rods is provided with a plurality of cleaning members that are arranged to extend into one of the plurality of first air inlets. Specifically, one of the plurality of cleaning member is a part that extends from one of the plurality of first extension rods, and when one of the plurality of cleaning members moves in one of the plurality of first air inlets, one of the plurality of first air inlets is cleaned.

[0012] The technical effect of the above improvement is: When the first ferrule rotates on the combustion chamber, it can synchronously drive one of the plurality of cleaning members to slide within one of the plurality of first air inlets, thereby effectively removing dust adhered to the hole wall of one of the plurality of first air inlets and ensuring normal air intake.

[0013] As a further improvement of the above solution, a movable ring is sleeved on the main shaft, a protruding second extension rod is arranged at one end of the movable ring, and an end of the second extension rod is provided with an outwardly protruding guide pin; a rotating member is fixed on an outer side surface of the first ferrule, and the rotating member is provided with a first guide portion slidably arranged with the guide pin; and a reset member for pulling back the rotating member is further arranged between the rotating member and the combustion chamber.

[0014] As a further improvement of the above solution, the main shaft is fixedly provided with a first toggle member arranged along its diameter direction, and a second toggle member capable of moving in contact with the first toggle member is arranged on an end face of the movable ring; and the first guide portion is obliquely arranged.

[0015] The technical effect of the aforementioned improvement is as follows: Through the toggling action of the first toggle member on the second toggle member, the movable ring is driven to rotate along with it. Under the drive of the second extension rod and the main shaft, the rotating member is synchronously driven to rotate. When the rotating member rotates, it can drive the first ferrule to rotate along with it, thereby driving one of the plurality of cleaning members to rotate and enter into one of the plurality of first air inlets, effectively cleaning one of the plurality of first air inlets. However, when the rotating member rotates to its limit position, it stops rotating. Under the guidance of the first guide portion, the guide pin slides within the first guide portion. At this point, the movable ring, under the toggling of the first toggle member, rotates while moving away from the first toggle member until the first toggle member no longer toggles the second toggle member. At this time, under the pulling force of the reset member, the rotating member and the first ferrule rotate in the reverse direction to reset, allowing one of the plurality of cleaning members to slide out of one of the plurality of first air inlets. Therefore, while one of the plurality of movable pins is pushing to clean one of the plurality of second air inlets, one of the plurality of first air inlets can also be synchronously cleaned. However, under the pulling force of the reset member, one of the plurality of cleaning members quickly retreats from one of the plurality of first air inlets, thereby preventing simultaneous blockage of one of the plurality of first air inlets and one of the plurality of second air inlets, which could otherwise lead to a situation where internal air intake is impossible and combustion cannot occur. When the main shaft rotates in reverse, it can drive the pusher to push the movable ring towards the side of the first toggle member until the first toggle member can come into contact with the second toggle member.

[0016] As a further improvement of the above solution, an inner lining ring is rotatably arranged on a periphery of the rotating member, a plurality of penetrating second guide portions are further arranged on the rotating member, and a plurality of limiting pins capable of moving in one of the plurality of second guide portions are arranged on the inner lining ring; and an outer circumference of the inner lining ring is fixedly provided with a housing, the housing and the combustion chamber are fixed to each other, and one of the plurality of first air inlets is completely covered.

[0017] The technical effects of the above improvements are: The housing is mainly arranged to isolate the air intake, facilitating air to fully enter the inner portion of the combustion chamber through either one of the plurality of first air inlets or one of the plurality of second air inlets. The inner lining ring primarily serves to support the rotation of the rotating member. Meanwhile, with the interaction between one of the plurality of limiting pins and one of the plurality of second guide portions, the rotation angle of the rotating member can be restricted, preventing excessive rotation range of the rotating member.

[0018] As a further improvement of the above solution, a plurality of volatilization nets are arranged on a circumferential side wall of the volatilization chamber, and positions of one of the plurality of volatilization nets and one of the plurality of second air inlets correspond to each other; and one of the plurality of first air inlets is arranged tangentially along a diameter of the combustion chamber, an end of one of the plurality of cleaning members is fixedly provided with a scraper blade, and the scraper blade protrudes outwards in a tangential direction of one of the plurality of cleaning members.

[0019] The technical effect of the above improvement is: By arranging one of the plurality of volatilization nets on the outer side of the volatilization chamber, corresponding to the position of one of the plurality of second air inlets, the atomized fuel can first mix and come into contact with air when sprayed out, resulting in a more thorough combustion and thus avoiding the formation of carbon deposits; the arranged tangential combustion chamber facilitates the formation of a cyclone when air enters the combustion chamber, ensuring a more thorough mixing with the fuel. Moreover, with the action of the scraper blade, it can ensure contact with the hole wall when interacting with first air inlets of different sizes, and the scraper blade also facilitates the reverse resetting of the first ferrule.

[0020] As a further improvement of the above solution, the self-dusting multi-ignition point co-heating fuel heater, further comprising a sealing cover arranged on the outer side of the combustion chamber and covering the ignition disk and one of the plurality of movable pins; a sealing cap is fixedly arranged at a front end of the sealing cover; an air inlet assembly for supplying air into the sealing cover is fixedly arranged on the sealing cap, and a fan blade of the air inlet assembly is coated with a coating for preventing electrostatic adsorption of dust; and the driving assembly is arranged on a front end face of the sealing cap.

[0021] As a further improvement of the above solution, a heat exchanger assembly is sleeved on the outer side of the combustion chamber, the heat exchanger assembly and the sealing cover are fixed to each other, and an exhaust pipe facilitating exhaust of the combustion chamber is arranged in the heat exchanger assembly.

[0022] The technical effect of the above improvements is: By arranging a coating on the fan blades of the air inlet assembly, the erosion and accumulation of dust on the blade surface, as well as the influence of frictional electric field forces, can be reduced. This reduction mitigates sudden changes in dynamic balance caused by dust during motor rotation, thereby decreasing the stress configuration on the supporting bearings and ultimately enhancing both the motor's service life and air volume efficiency.BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to enable a person skilled in the art to better understand the technical solutions, the technical solutions are described in detail below with reference to the embodiments, and the description of the present disclosure is merely exemplary and explanatory, and should not have any limiting effect on the protection scope of the present disclosure.

[0026] Please refer to FIGS. 1-13. In a specific embodiment, the self-dedusting multi-ignition-point co-heating fuel heater comprises a combustion chamber 10. The combustion chamber 10 is in the shape of a circular tube, and an outer side surface of the combustion chamber 10 is provided with a plurality of first air inlets 101 penetrating inside and outside. As can be seen in FIGS. 6 and 7, one of the plurality of first air inlets 101 is arranged tangentially along a diameter of the combustion chamber 10. This arrangement ensures that during air intake, air enters the combustion chamber 10 and generates a cyclonic flow, thereby facilitating thorough mixing with the fuel.

[0027] An ignition disk 11 is fixedly arranged at an end, close to an air inlet end, of the combustion chamber 10; the ignition disk 11 covers the air inlet end of the combustion chamber 10 and is fixedly arranged with each other; a volatilization chamber 111 is arranged in the ignition disk 11; referring to FIG. 11, a feeding pipe 112 is connected to one side of the volatilization chamber 111; fuel to be combusted enters the volatilization chamber 111 from the feeding pipe 112; the volatilization chamber 111 is of a hollow cylindrical structure; and a plurality of volatilization nets 115 are arranged on a circumferential side wall of the volatilization chamber 111.

[0028] An igniter 113 is further arranged in the ignition disk 11; an end face of the ignition disk 11 is provided with a plurality of second air inlets 114 communicating with an inner portion of the combustion chamber 10; positions of one of the plurality of volatilization nets 115 and one of the plurality of second air inlets 114 correspond to each other; the plurality of second air inlets 114 are arranged in a circumferential array around the volatilization chamber 111; in the embodiment, one of the plurality of second air inlets 114 is arranged according to the air inlet wind power and the settling zone of the oil gravity density. Six second air inlets 114 and six volatilization nets 115 are correspondingly arranged. The arrangement of the six second air inlets 114 facilitates the dispersion of air intake, enabling the burner to maintain combustion even in dusty environments and reducing the occurrence of flame interruption in the burner.

[0029] An air inlet side of the ignition disk 11 is movably provided with a movable pin 12 that is capable of inserting into one of the plurality of second air inlets 114, and a plurality of movable pins 12 are arranged, thereby cleaning one of the plurality of second air inlets 114, and one of the plurality of movable pins 12 is connected to a driving assembly 27 for driving one of the plurality of movable pins 12 to move. Referring to FIG. 2 or FIG. 3, in this embodiment, the driving assembly 27 employed is a motor. When activated, the motor drives one of the plurality of movable pins 12 to insert into one of the plurality of second air inlets 114 and move within it. When one of the plurality of movable pins 12 is inserted into one of the plurality of second air inlets 114, one of the plurality of movable pins 12 pushes away any dust present in the aperture of one of the plurality of second air inlets 114, thereby facilitating the smooth entry of air into the combustion chamber 10 through one of the plurality of second air inlets 114 and enhancing combustion efficiency.

[0030] As shown in FIGS. 5, 6, 7, 8 and 9, as a preferred mode of the embodiment, in order to enable one of the plurality of movable pins 12 to automatically retract and open one of the plurality of second air inlets 114 after insertion, a connecting plate 14 is arranged between the plurality of movable pins 12, all the movable pins 12 are fixed together through the connecting plate 14, and synchronous control is achieved; the connecting plate 14 and the ignition disk 11 are arranged in a sliding mode, and the connecting plate 14 and the ignition disk 11 can only slide with each other and cannot rotate with each other, so that it can be guaranteed that one of the plurality of movable pins 12 can be smoothly inserted into one of the plurality of second air inlets 114, angle deflection cannot occur, one of the plurality of movable pins 12 cannot be inserted, a spring 15 is arranged between the connecting plate 14 and the ignition disk 11, and the spring 15 abuts against the connecting plate 14 outwards, so that one of the plurality of movable pins 12 slides out of one of the plurality of second air inlets 114.

[0031] An outer end face of the ignition disk 11 is provided with a guide piece 16 protruding outwards. In this embodiment, the guide piece 16 is a guide column fixed on the end surface of the ignition disk 11, a push head 17 capable of jacking one of the plurality of movable pins 12 is slidably arranged on the guide piece 16, a main shaft 18 is in threaded connection with the push head 17, and the main shaft 18 is in power connection with the driving assembly 27. When the motor is started, the main shaft 18 can be driven to rotate, the main shaft 18 drives the push head 17 to move towards one side of the connecting plate 14, and under the guide of the guide piece 16, the push head 17 presses against the connecting plate 14, so that one of the plurality of movable pins 12 is inserted into one of the plurality of second air inlets 114, and dust in one of the plurality of second air inlets 114 is cleaned away.

[0032] As a preferred embodiment of the above embodiment, an outer side of the combustion chamber 10 is rotatably sleeved with a first ferrule 13, and the first ferrule 13 is provided with a plurality of first extension rods 131 extending in its axial direction. In this embodiment, one of the plurality of first extension rods 131 is part of the first ferrule 13. One of the plurality of first extension rods 131 is provided with a plurality of cleaning members 132 that are arranged to extend into one of the plurality of first air inlets 101. Specifically, one of the plurality of cleaning members 132 is a part extending on one of the plurality of first extension rods 131. An end of one of the plurality of cleaning members 132 is fixedly provided with a scraper blade 133, and the scraper blade 133 protrudes outwards in a tangential direction of one of the plurality of cleaning members 132 and is arranged at an inclined angle, as shown in FIG. 10. When one of the plurality of cleaning members 132 moves in one of the plurality of first air inlets 101, one of the plurality of first air inlets 101 is cleand. The scraper blade 133, fixed at the end of one of the plurality of cleaning members 132, ensures contact with the inner wall of one of the plurality of first air inlets 101 of varying sizes when one of the plurality of cleaning members 132 enters, thereby cleaning dust accumulated on one of the plurality of first air inlets 101. Furthermore, due to the inclined arrangement of the scraper blade 133, when one of the plurality of cleaning members 132 retreats from one of the plurality of first air inlets 101, it can expand through its own deformation, facilitating quick and easy withdrawal. Additionally, in its inclined state, the scraper blade 133 can guide the airflow before entering one of the plurality of first air inlets 101, facilitating the airflow through one of the plurality of first air inlets 101 into the combustion chamber 10 for combustion.

[0033] As shown in FIGS. 9, 10, and 13, as a preferred embodiment of the above embodiment, a movable ring 19 is sleeved on the main shaft 18. In this embodiment, the main shaft 18 and the movable ring 19 can slide and rotate relative to each other. A protruding second extension rod 191 is arranged at one end of the movable ring 19, as shown in FIG. 10. The second extension rod 191 is specifically part of the movable ring 19, extending along its axial direction. An end of the second extension rod 191 is provided with an outwardly protruding guide pin 192. In this embodiment, the guide pin 192 is specifically an outwardly protruding cylindrical pin arranged on the second extension rod 191.

[0034] A rotating member 20 is fixed on an outer side surface of the first ferrule 13. In this embodiment, the rotating member 20 is a rotating cylinder. Specifically, the rotating member 20 is sleeved on the outer side of the first ferrule 13 with a gap between them, which is used for airflow, and they are fixed to each other through welded connecting blocks, as shown in FIGS. 5 and 6. The rotating member 20 is provided with a first guide portion 201 slidably arranged with the guide pin 192. In this embodiment, the first guide portion 201 is a through elongated slot arranged in an inclined manner. Specifically, the inclination direction is along the direction of the rotating member 20 following the actuation of the movable ring 19, gradually moving away from the movable ring 19, as shown in FIG. 10.

[0035] A reset member 21 for pulling back the rotating member 20 is further arranged between the rotating member 20 and the combustion chamber 10. In this embodiment, the reset member 21 is a tension spring. In order to ensure that the movable ring 19 can synchronously rotate the rotating member 20 during its rotation, a rough surface is added between the second extension rod 191 and the rotating member 20 to increase friction between them, and it is ensured that the friction between the second extension rod 191 and the rotating member 20 is greater than the pulling force of the reset member 21. Additionally, a limiting groove 203 is arranged on the first guide portion 201. The limiting groove 203 is an inwardly recessed part of the first guide portion 201, with a smooth transition between them, as shown in FIG. 13. The limiting groove 203 can partially restrict the guide pin 192, ensuring that when the movable ring 19 drives the rotating member 20 to rotate, the rotating member 20 first follows the movable ring 19 to perform a rotational movement. Then, when the rotating member 20 cannot rotate further, the guide pin 192 can move within the first guide portion 201.

[0036] As shown in FIG. 10, as a preferred embodiment of the above embodiment, the main shaft 18 is fixedly provided with a first toggle member 181 arranged along its diameter direction, and a second toggle member 193 capable of moving in contact with the first toggle member 181 is arranged on an end face of the movable ring 19. The second toggle member 193 is arranged along the axial direction of the movable ring 19. Both the second toggle member 193 and the first toggle member 181 are configured as outwardly protruding levers. When the main shaft 18 rotates, the first toggle member 181 comes into contact with the second toggle member 193 and synchronously drives the second toggle member 193 to rotate, thereby prompting the rotation of the movable ring 19. At this point, the movable ring 19 can drive the rotating member 20 to rotate, allowing the first ferrule 13 to clean one of the plurality of first air inlets 101. When the main shaft 18 rotates, it also synchronously drives the push head 17 to move towards one side of the connecting plate 14, so the rotation of the main shaft 18 can synchronously enable the cleaning of both one of the plurality of second air inlets 114 and one of the plurality of first air inlets 101.

[0037] When the rotating member 20 cannot rotate further, the first toggle member 181 continues to rotate in contact with the second toggle member 193. At this point, under the guidance of the first guide portion 201, the guide pin 192 moves within the first guide portion 201, causing the movable ring 19 to rotate while also moving towards one side of the rotating member 20, until contact between the first toggle member 181 and the second toggle member 193 is lost. At this point, the first toggle member 181 no longer has a toggling effect on the second toggle member 193. Under the pulling force of the reset member 21, the rotating member 20 rotates in reverse to reset, and the movable ring 19 also follows to reset, thereby pulling out one of the plurality of first extension rods 131 inserted into one of the plurality of first air inlets 101. When the main shaft 18 continues to rotate, it will not toggle the second toggle member 193 again but will drive the push head 17 to press against the connecting plate 14 to complete the cleaning of one of the plurality of second air inlets 114. Therefore, it can be ensured that when cleaning one of the plurality of first air inlets 101 and one of the plurality of second air inlets 114, one of them is always in an open state, avoiding complete blockage of air intake and ensuring the combustion of fuel within the heater without flame extinction. When the driving assembly 27 drives the main shaft 18 to rotate in reverse, although the first toggle member 181 cannot toggle the second toggle member 193, the push head 17 will move towards one side of the movable ring 19 until it comes into contact with the movable ring 19 and pushes it towards one side of the main shaft 18. At this point, with the guidance of the first guide portion 201, the guide pin 192 moves, allowing the first toggle member 181 and the second toggle member 193 to come into contact with each other again, until the guide pin 192 can no longer move within the first guide portion 201 and the driving assembly 27 stops driving the rotation of the main shaft 18.

[0038] As shown in FIG. 9, as a preferred embodiment of the above embodiment, an inner lining ring 23 is rotatably arranged on a periphery of the rotating member 20. The provided inner lining ring 23 mainly facilitates the rotation of the housing 22. A plurality of penetrating second guide portions 202 are further arranged on the rotating member 20. One of the plurality of second guide portions 202 is also set as elongated, penetrating slot, but it is arranged along the outer circumference of the rotating member 20 without inclination, solely for limiting the rotation of one of the plurality of second guide portions 202. A plurality of limiting pins capable of moving in one of the plurality of second guide portions 202 are arranged on the inner lining ring 23. The movement of the limiting pins within one of the plurality of second guide portions 202 primarily serves to restrict the rotation range of the rotating member 20.

[0039] An outer circumference of the inner lining ring 23 is fixedly provided with a housing 22, the housing 22 and the combustion chamber 10 are fixed to each other, and one of the plurality of first air inlets 101 is completely covered. The housing 22 is mainly used to isolate the air delivered by the air inlet assembly 26 from the outside, ensuring that all incoming air can enter the combustion chamber 10 through one of the plurality of first air inlets 101 and one of the plurality of second air inlets 114 to participate in combustion.

[0040] As shown in FIGS. 1, 2, and 4, as a preferred mode of the above embodiment, it further comprises a sealing cover 24 arranged on the outer side of the combustion chamber 10 and covering the ignition disk 11 and one of the plurality of movable pins 12. The sealing cover 24 is tubular-shaped, and the housing 22 and the sealing cover 24 are mutually sealed and fixedly arranged. A sealing cap 25 is fixedly arranged at a front end of the sealing cover 24. The driving assembly 27 is arranged on a front end face of the sealing cap 25. An air inlet assembly 26 for supplying air into the sealing cover 24 is fixedly arranged on the sealing cap 25, and a fan blade of the air inlet assembly 26 is coated with a coating for preventing electrostatic adsorption of dust. The applied coating is an organic substance coated onto the blade, which can utilize the attachment effect to effectively address the issues of dust erosion and the influence of frictional electric field forces on the blade surface; thereby enhancing motor lifespan and volumetric efficiency.

[0041] As a preferred embodiment of the above embodiment, a heat exchanger assembly 28 is sleeved on the outer side of the combustion chamber 10. The heat exchanger assembly 28 and the sealing cover 24 are fixed to each other. Specifically, the housing 22 is fixed between the sealing cover 24 and the heat exchanger assembly 28. Moreover, an exhaust pipe 29 facilitating exhaust of the combustion chamber 10 is arranged in the heat exchanger assembly 28. The heat exchanger assembly 28 primarily contains water, which is circulated using a water pump. The water in the heat exchanger assembly 28 carries away the generated combustion heat for utilization.

[0042] The specific working principle of the present disclosure is as follows: The air inlet assembly 26 is activated to introduce external air, which is then delivered into the combustion chamber 10 through one of the plurality of second air inlets 114 and one of the plurality of first air inlets 101 for combustion. The feeding pipe 112 introduces fuel into one of the plurality of volatilization nets 115, where it volatilizes and mixes with air. After the igniter 113 ignites, the fuel is ignited and generates heat. The water flowing in the heat exchanger assembly 28 absorbs the generated heat and carries it away for utilization; when used in a dusty environment and dust removal is required, the driving assembly 27 is activated. The driving assembly 27 drives the main shaft 18 to rotate. As the main shaft 18 rotates, it drives the first toggle member 181 to rotate. The first toggle member 181 toggles the second toggle member 193 to rotate. The second toggle member 193 drives the movable ring 19 to rotate, which synchronously drives the rotating member 20 to rotate. As the rotating member 20 rotates, it drives the first ferrule 13 to rotate, causing one of the plurality of cleaning members 132 and the scraper blade 133 to extend into one of the plurality of first air inlets 101 to clean it; during the continuous rotation of the main shaft 18, the rotating member 20, limited by one of the plurality of limiting pins on the inner lining ring 23, cannot continue to rotate. At this point, the first toggle member 181 continues to toggle the second toggle member 193 to rotate. The guide pin 192, guided by the first guide portion 201, moves in a direction away from the main shaft 18 until the first toggle member 181 and the second toggle member 193 are completely separated. Afterwards, under the tension of the reset member 21, the rotating member 20 and the first ferrule 13 rotate in reverse to reset; and the main shaft 18 continues to rotate, driving the push head 17 to move towards one side of the connecting plate 14, thereby pushing the connecting plate 14 and one of the plurality of movable pins 12 to move. This causes one of the plurality of movable pins 12 to extend into one of the plurality of second air inlets 114 to clean the dust inside. Therefore, during each cleaning process, the cleaning of one of the plurality of first air inlets 101 and one of the plurality of second air inlets 114 is separated to avoid simultaneous cleaning. This prevents air from being blocked and unable to enter the combustion chamber 10 for combustion, which could lead to flame interruption. Additionally, the plurality of second air inlets 114 are positioned corresponding to one of the plurality of volatilization nets 115, allowing for more uniform mixing of fuel and air, reducing incomplete combustion, and thereby reducing carbon deposits from combustion in the combustion chamber 10.

TECHNICAL FIELD

[0001] The present disclosure belongs to the technical field of automobile accessories, and particularly relates to a self-dedusting multi-ignition-point co-heating fuel heater.BACKGROUND

[0002] The fuel heater is a small heating device that releases a large amount of combustion heat by burning liquid fuels such as diesel, gasoline, natural gas, and bio-oils currently available in the market. The mechanical structure of the fuel heater separates these fuels and utilizes the material density of the mechanism to form an oil film. This oil film is then mixed and atomized with combustion-supporting air before being ignited by the ignition component. The structure of the fuel heater and its connections include a motor, a combustion-supporting fan, an oil delivery device, a volatilization mesh, an ignition plug, a combustion chamber, and a heat exchanger.

[0003] Currently, the market for fuel heaters both domestically and internationally offers a diverse range of products with similar structures and performance. Market application surveys and customer feedback have revealed the following issues: The environments in which heaters are currently used are limited. In coal mines, mining sites, and dusty environments, both domestic and international heaters experience problems such as failure to ignite and burn or low combustion efficiency. Additionally, the lifespan of the heater's motor is significantly reduced, noise levels increase, and emission components do not meet environmental standards. The combustion chamber accumulates severe carbon deposits, and issues such as burnout and deformation occur, causing the heater to lose its primary function.

[0004] Therefore, there is a need for a fuel heater that can address the aforementioned problems.SUMMARY

[0005] In view of the aforementioned problems, the present disclosure provides a self-dedusting multi-ignition-point co-heating fuel heater, which aims to solve the problems associated with the heater's ignition function failure and flame interruption during combustion in dusty environments, as well as to mitigate the accumulation of carbon deposits within the combustion chamber and enhance the low heat conversion efficiency of the fuel.

[0006] In order to achieve the above object, the technical solution adopted by the present disclosure is: a self-dedusting multi-ignition-point co-heating fuel heater, comprising a combustion chamber, wherein an outer side surface of the combustion chamber is provided with a plurality of first air inlets penetrating inside and outside; an ignition disk is fixedly arranged at an end, close to an air inlet end, of the combustion chamber, a volatilization chamber is arranged in the ignition disk, a feeding pipe is connected to one side of the volatilization chamber, and an igniter is further arranged in the ignition disk; and an end face of the ignition disk is provided with a plurality of second air inlets communicating with an inner portion of the combustion chamber, the plurality of second air inlets are arranged in a circumferential array around the volatilization chamber, an air inlet side of the ignition disk is movably provided with a movable pin that is capable of inserting into one of the plurality of second air inlets, thereby cleaning one of the plurality of second air inlets, and the movable pin is connected to a driving assembly for driving the movable pin to move.

[0007] Compared with the prior art, the beneficial effects of the present disclosure are as follows: By arranging a plurality second air inlets, air can enter the combustion chamber from multiple points, thereby dispersing the air intake. This allows for ignition and combustion even in dusty environments or environments with severely polluted air quality, reducing the probability of single-cavity flameout. One of the plurality of movable pins that is arranged can clean the hole wall of one of the plurality of second air inlets. When dust blocks one of the plurality of second air inlets, the penetration of one of the plurality of movable pins ensures that one of the plurality of second air inlets remain unblocked for air intake. The heater can still ensure the volatility density of the fuel and its proper mixing with air in dusty environments, as well as reduce the impact of dust-laden air on combustion and the formation of carbon deposits. With normal use, there will be no flameout.

[0008] As a further improvement of the above solution, an outer end face of the ignition disk is provided with a guide piece protruding outwards, a push head capable of jacking the movable pin is slidably arranged on the guide piece, a main shaft is in threaded connection with the push head, and the main shaft is in power connection with the driving assembly.

[0009] As a further improvement of the above solution, a plurality of movable pins are arranged, a connecting plate is arranged between the plurality of movable pins, the connecting plate and the ignition disk are arranged in a sliding mode, a spring is arranged between the connecting plate and the ignition disk, and the spring abuts against the connecting plate, so that one of the plurality of movable pins slides out of one of the plurality of second air inlets.

[0010] The technical effect of the aforementioned improvement is as follows: By arranging a push head, it can be driven to move towards one side of the connecting plate when the main shaft rotates. After contact with the connecting plate, the push head will push the connecting plate and one of the plurality of movable pins to move synchronously, so that one of the plurality of movable pins enters one of the plurality of second air inlets and cleans it thoroughly, facilitating normal combustion within the combustion chamber. The arranged spring exerts a reverse pushing force on the connecting plate, which can push one of the plurality of movable pins to extend outward from one of the plurality of second air inlets when the push head moves in the reverse direction and loses its pushing force on the connecting plate, allowing one of the plurality of second air inlets to intake air.

[0011] As a further improvement of the above solution, an outer side of the combustion chamber is rotatably sleeved with a first ferrule, the first ferrule is provided with a plurality of first extension rods extending in its axial direction, one of the plurality of first extension rods is provided with a plurality of cleaning members that are arranged to extend into one of the plurality of first air inlets. Specifically, one of the plurality of cleaning member is a part that extends from one of the plurality of first extension rods, and when one of the plurality of cleaning members moves in one of the plurality of first air inlets, one of the plurality of first air inlets is cleaned.

[0012] The technical effect of the above improvement is: When the first ferrule rotates on the combustion chamber, it can synchronously drive one of the plurality of cleaning members to slide within one of the plurality of first air inlets, thereby effectively removing dust adhered to the hole wall of one of the plurality of first air inlets and ensuring normal air intake.

[0013] As a further improvement of the above solution, a movable ring is sleeved on the main shaft, a protruding second extension rod is arranged at one end of the movable ring, and an end of the second extension rod is provided with an outwardly protruding guide pin; a rotating member is fixed on an outer side surface of the first ferrule, and the rotating member is provided with a first guide portion slidably arranged with the guide pin; and a reset member for pulling back the rotating member is further arranged between the rotating member and the combustion chamber.

[0014] As a further improvement of the above solution, the main shaft is fixedly provided with a first toggle member arranged along its diameter direction, and a second toggle member capable of moving in contact with the first toggle member is arranged on an end face of the movable ring; and the first guide portion is obliquely arranged.

[0015] The technical effect of the aforementioned improvement is as follows: Through the toggling action of the first toggle member on the second toggle member, the movable ring is driven to rotate along with it. Under the drive of the second extension rod and the main shaft, the rotating member is synchronously driven to rotate. When the rotating member rotates, it can drive the first ferrule to rotate along with it, thereby driving one of the plurality of cleaning members to rotate and enter into one of the plurality of first air inlets, effectively cleaning one of the plurality of first air inlets. However, when the rotating member rotates to its limit position, it stops rotating. Under the guidance of the first guide portion, the guide pin slides within the first guide portion. At this point, the movable ring, under the toggling of the first toggle member, rotates while moving away from the first toggle member until the first toggle member no longer toggles the second toggle member. At this time, under the pulling force of the reset member, the rotating member and the first ferrule rotate in the reverse direction to reset, allowing one of the plurality of cleaning members to slide out of one of the plurality of first air inlets. Therefore, while one of the plurality of movable pins is pushing to clean one of the plurality of second air inlets, one of the plurality of first air inlets can also be synchronously cleaned. However, under the pulling force of the reset member, one of the plurality of cleaning members quickly retreats from one of the plurality of first air inlets, thereby preventing simultaneous blockage of one of the plurality of first air inlets and one of the plurality of second air inlets, which could otherwise lead to a situation where internal air intake is impossible and combustion cannot occur. When the main shaft rotates in reverse, it can drive the pusher to push the movable ring towards the side of the first toggle member until the first toggle member can come into contact with the second toggle member.

[0016] As a further improvement of the above solution, an inner lining ring is rotatably arranged on a periphery of the rotating member, a plurality of penetrating second guide portions are further arranged on the rotating member, and a plurality of limiting pins capable of moving in one of the plurality of second guide portions are arranged on the inner lining ring; and an outer circumference of the inner lining ring is fixedly provided with a housing, the housing and the combustion chamber are fixed to each other, and one of the plurality of first air inlets is completely covered.

[0017] The technical effects of the above improvements are: The housing is mainly arranged to isolate the air intake, facilitating air to fully enter the inner portion of the combustion chamber through either one of the plurality of first air inlets or one of the plurality of second air inlets. The inner lining ring primarily serves to support the rotation of the rotating member. Meanwhile, with the interaction between one of the plurality of limiting pins and one of the plurality of second guide portions, the rotation angle of the rotating member can be restricted, preventing excessive rotation range of the rotating member.

[0018] As a further improvement of the above solution, a plurality of volatilization nets are arranged on a circumferential side wall of the volatilization chamber, and positions of one of the plurality of volatilization nets and one of the plurality of second air inlets correspond to each other; and one of the plurality of first air inlets is arranged tangentially along a diameter of the combustion chamber, an end of one of the plurality of cleaning members is fixedly provided with a scraper blade, and the scraper blade protrudes outwards in a tangential direction of one of the plurality of cleaning members.

[0019] The technical effect of the above improvement is: By arranging one of the plurality of volatilization nets on the outer side of the volatilization chamber, corresponding to the position of one of the plurality of second air inlets, the atomized fuel can first mix and come into contact with air when sprayed out, resulting in a more thorough combustion and thus avoiding the formation of carbon deposits; the arranged tangential combustion chamber facilitates the formation of a cyclone when air enters the combustion chamber, ensuring a more thorough mixing with the fuel. Moreover, with the action of the scraper blade, it can ensure contact with the hole wall when interacting with first air inlets of different sizes, and the scraper blade also facilitates the reverse resetting of the first ferrule.

[0020] As a further improvement of the above solution, the self-dusting multi-ignition point co-heating fuel heater, further comprising a sealing cover arranged on the outer side of the combustion chamber and covering the ignition disk and one of the plurality of movable pins; a sealing cap is fixedly arranged at a front end of the sealing cover; an air inlet assembly for supplying air into the sealing cover is fixedly arranged on the sealing cap, and a fan blade of the air inlet assembly is coated with a coating for preventing electrostatic adsorption of dust; and the driving assembly is arranged on a front end face of the sealing cap.

[0021] As a further improvement of the above solution, a heat exchanger assembly is sleeved on the outer side of the combustion chamber, the heat exchanger assembly and the sealing cover are fixed to each other, and an exhaust pipe facilitating exhaust of the combustion chamber is arranged in the heat exchanger assembly.

[0022] The technical effect of the above improvements is: By arranging a coating on the fan blades of the air inlet assembly, the erosion and accumulation of dust on the blade surface, as well as the influence of frictional electric field forces, can be reduced. This reduction mitigates sudden changes in dynamic balance caused by dust during motor rotation, thereby decreasing the stress configuration on the supporting bearings and ultimately enhancing both the motor's service life and air volume efficiency.BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to enable a person skilled in the art to better understand the technical solutions, the technical solutions are described in detail below with reference to the embodiments, and the description of the present disclosure is merely exemplary and explanatory, and should not have any limiting effect on the protection scope of the present disclosure.

[0026] Please refer to FIGS. 1-13. In a specific embodiment, the self-dedusting multi-ignition-point co-heating fuel heater comprises a combustion chamber 10. The combustion chamber 10 is in the shape of a circular tube, and an outer side surface of the combustion chamber 10 is provided with a plurality of first air inlets 101 penetrating inside and outside. As can be seen in FIGS. 6 and 7, one of the plurality of first air inlets 101 is arranged tangentially along a diameter of the combustion chamber 10. This arrangement ensures that during air intake, air enters the combustion chamber 10 and generates a cyclonic flow, thereby facilitating thorough mixing with the fuel.

[0027] An ignition disk 11 is fixedly arranged at an end, close to an air inlet end, of the combustion chamber 10; the ignition disk 11 covers the air inlet end of the combustion chamber 10 and is fixedly arranged with each other; a volatilization chamber 111 is arranged in the ignition disk 11; referring to FIG. 11, a feeding pipe 112 is connected to one side of the volatilization chamber 111; fuel to be combusted enters the volatilization chamber 111 from the feeding pipe 112; the volatilization chamber 111 is of a hollow cylindrical structure; and a plurality of volatilization nets 115 are arranged on a circumferential side wall of the volatilization chamber 111.

[0028] An igniter 113 is further arranged in the ignition disk 11; an end face of the ignition disk 11 is provided with a plurality of second air inlets 114 communicating with an inner portion of the combustion chamber 10; positions of one of the plurality of volatilization nets 115 and one of the plurality of second air inlets 114 correspond to each other; the plurality of second air inlets 114 are arranged in a circumferential array around the volatilization chamber 111; in the embodiment, one of the plurality of second air inlets 114 is arranged according to the air inlet wind power and the settling zone of the oil gravity density. Six second air inlets 114 and six volatilization nets 115 are correspondingly arranged. The arrangement of the six second air inlets 114 facilitates the dispersion of air intake, enabling the burner to maintain combustion even in dusty environments and reducing the occurrence of flame interruption in the burner.

[0029] An air inlet side of the ignition disk 11 is movably provided with a movable pin 12 that is capable of inserting into one of the plurality of second air inlets 114, and a plurality of movable pins 12 are arranged, thereby cleaning one of the plurality of second air inlets 114, and one of the plurality of movable pins 12 is connected to a driving assembly 27 for driving one of the plurality of movable pins 12 to move. Referring to FIG. 2 or FIG. 3, in this embodiment, the driving assembly 27 employed is a motor. When activated, the motor drives one of the plurality of movable pins 12 to insert into one of the plurality of second air inlets 114 and move within it. When one of the plurality of movable pins 12 is inserted into one of the plurality of second air inlets 114, one of the plurality of movable pins 12 pushes away any dust present in the aperture of one of the plurality of second air inlets 114, thereby facilitating the smooth entry of air into the combustion chamber 10 through one of the plurality of second air inlets 114 and enhancing combustion efficiency.

[0030] As shown in FIGS. 5, 6, 7, 8 and 9, as a preferred mode of the embodiment, in order to enable one of the plurality of movable pins 12 to automatically retract and open one of the plurality of second air inlets 114 after insertion, a connecting plate 14 is arranged between the plurality of movable pins 12, all the movable pins 12 are fixed together through the connecting plate 14, and synchronous control is achieved; the connecting plate 14 and the ignition disk 11 are arranged in a sliding mode, and the connecting plate 14 and the ignition disk 11 can only slide with each other and cannot rotate with each other, so that it can be guaranteed that one of the plurality of movable pins 12 can be smoothly inserted into one of the plurality of second air inlets 114, angle deflection cannot occur, one of the plurality of movable pins 12 cannot be inserted, a spring 15 is arranged between the connecting plate 14 and the ignition disk 11, and the spring 15 abuts against the connecting plate 14 outwards, so that one of the plurality of movable pins 12 slides out of one of the plurality of second air inlets 114.

[0031] An outer end face of the ignition disk 11 is provided with a guide piece 16 protruding outwards. In this embodiment, the guide piece 16 is a guide column fixed on the end surface of the ignition disk 11, a push head 17 capable of jacking one of the plurality of movable pins 12 is slidably arranged on the guide piece 16, a main shaft 18 is in threaded connection with the push head 17, and the main shaft 18 is in power connection with the driving assembly 27. When the motor is started, the main shaft 18 can be driven to rotate, the main shaft 18 drives the push head 17 to move towards one side of the connecting plate 14, and under the guide of the guide piece 16, the push head 17 presses against the connecting plate 14, so that one of the plurality of movable pins 12 is inserted into one of the plurality of second air inlets 114, and dust in one of the plurality of second air inlets 114 is cleaned away.

[0032] As a preferred embodiment of the above embodiment, an outer side of the combustion chamber 10 is rotatably sleeved with a first ferrule 13, and the first ferrule 13 is provided with a plurality of first extension rods 131 extending in its axial direction. In this embodiment, one of the plurality of first extension rods 131 is part of the first ferrule 13. One of the plurality of first extension rods 131 is provided with a plurality of cleaning members 132 that are arranged to extend into one of the plurality of first air inlets 101. Specifically, one of the plurality of cleaning members 132 is a part extending on one of the plurality of first extension rods 131. An end of one of the plurality of cleaning members 132 is fixedly provided with a scraper blade 133, and the scraper blade 133 protrudes outwards in a tangential direction of one of the plurality of cleaning members 132 and is arranged at an inclined angle, as shown in FIG. 10. When one of the plurality of cleaning members 132 moves in one of the plurality of first air inlets 101, one of the plurality of first air inlets 101 is cleand. The scraper blade 133, fixed at the end of one of the plurality of cleaning members 132, ensures contact with the inner wall of one of the plurality of first air inlets 101 of varying sizes when one of the plurality of cleaning members 132 enters, thereby cleaning dust accumulated on one of the plurality of first air inlets 101. Furthermore, due to the inclined arrangement of the scraper blade 133, when one of the plurality of cleaning members 132 retreats from one of the plurality of first air inlets 101, it can expand through its own deformation, facilitating quick and easy withdrawal. Additionally, in its inclined state, the scraper blade 133 can guide the airflow before entering one of the plurality of first air inlets 101, facilitating the airflow through one of the plurality of first air inlets 101 into the combustion chamber 10 for combustion.

[0033] As shown in FIGS. 9, 10, and 13, as a preferred embodiment of the above embodiment, a movable ring 19 is sleeved on the main shaft 18. In this embodiment, the main shaft 18 and the movable ring 19 can slide and rotate relative to each other. A protruding second extension rod 191 is arranged at one end of the movable ring 19, as shown in FIG. 10. The second extension rod 191 is specifically part of the movable ring 19, extending along its axial direction. An end of the second extension rod 191 is provided with an outwardly protruding guide pin 192. In this embodiment, the guide pin 192 is specifically an outwardly protruding cylindrical pin arranged on the second extension rod 191.

[0034] A rotating member 20 is fixed on an outer side surface of the first ferrule 13. In this embodiment, the rotating member 20 is a rotating cylinder. Specifically, the rotating member 20 is sleeved on the outer side of the first ferrule 13 with a gap between them, which is used for airflow, and they are fixed to each other through welded connecting blocks, as shown in FIGS. 5 and 6. The rotating member 20 is provided with a first guide portion 201 slidably arranged with the guide pin 192. In this embodiment, the first guide portion 201 is a through elongated slot arranged in an inclined manner. Specifically, the inclination direction is along the direction of the rotating member 20 following the actuation of the movable ring 19, gradually moving away from the movable ring 19, as shown in FIG. 10.

[0035] A reset member 21 for pulling back the rotating member 20 is further arranged between the rotating member 20 and the combustion chamber 10. In this embodiment, the reset member 21 is a tension spring. In order to ensure that the movable ring 19 can synchronously rotate the rotating member 20 during its rotation, a rough surface is added between the second extension rod 191 and the rotating member 20 to increase friction between them, and it is ensured that the friction between the second extension rod 191 and the rotating member 20 is greater than the pulling force of the reset member 21. Additionally, a limiting groove 203 is arranged on the first guide portion 201. The limiting groove 203 is an inwardly recessed part of the first guide portion 201, with a smooth transition between them, as shown in FIG. 13. The limiting groove 203 can partially restrict the guide pin 192, ensuring that when the movable ring 19 drives the rotating member 20 to rotate, the rotating member 20 first follows the movable ring 19 to perform a rotational movement. Then, when the rotating member 20 cannot rotate further, the guide pin 192 can move within the first guide portion 201.

[0036] As shown in FIG. 10, as a preferred embodiment of the above embodiment, the main shaft 18 is fixedly provided with a first toggle member 181 arranged along its diameter direction, and a second toggle member 193 capable of moving in contact with the first toggle member 181 is arranged on an end face of the movable ring 19. The second toggle member 193 is arranged along the axial direction of the movable ring 19. Both the second toggle member 193 and the first toggle member 181 are configured as outwardly protruding levers. When the main shaft 18 rotates, the first toggle member 181 comes into contact with the second toggle member 193 and synchronously drives the second toggle member 193 to rotate, thereby prompting the rotation of the movable ring 19. At this point, the movable ring 19 can drive the rotating member 20 to rotate, allowing the first ferrule 13 to clean one of the plurality of first air inlets 101. When the main shaft 18 rotates, it also synchronously drives the push head 17 to move towards one side of the connecting plate 14, so the rotation of the main shaft 18 can synchronously enable the cleaning of both one of the plurality of second air inlets 114 and one of the plurality of first air inlets 101.

[0037] When the rotating member 20 cannot rotate further, the first toggle member 181 continues to rotate in contact with the second toggle member 193. At this point, under the guidance of the first guide portion 201, the guide pin 192 moves within the first guide portion 201, causing the movable ring 19 to rotate while also moving towards one side of the rotating member 20, until contact between the first toggle member 181 and the second toggle member 193 is lost. At this point, the first toggle member 181 no longer has a toggling effect on the second toggle member 193. Under the pulling force of the reset member 21, the rotating member 20 rotates in reverse to reset, and the movable ring 19 also follows to reset, thereby pulling out one of the plurality of first extension rods 131 inserted into one of the plurality of first air inlets 101. When the main shaft 18 continues to rotate, it will not toggle the second toggle member 193 again but will drive the push head 17 to press against the connecting plate 14 to complete the cleaning of one of the plurality of second air inlets 114. Therefore, it can be ensured that when cleaning one of the plurality of first air inlets 101 and one of the plurality of second air inlets 114, one of them is always in an open state, avoiding complete blockage of air intake and ensuring the combustion of fuel within the heater without flame extinction. When the driving assembly 27 drives the main shaft 18 to rotate in reverse, although the first toggle member 181 cannot toggle the second toggle member 193, the push head 17 will move towards one side of the movable ring 19 until it comes into contact with the movable ring 19 and pushes it towards one side of the main shaft 18. At this point, with the guidance of the first guide portion 201, the guide pin 192 moves, allowing the first toggle member 181 and the second toggle member 193 to come into contact with each other again, until the guide pin 192 can no longer move within the first guide portion 201 and the driving assembly 27 stops driving the rotation of the main shaft 18.

[0038] As shown in FIG. 9, as a preferred embodiment of the above embodiment, an inner lining ring 23 is rotatably arranged on a periphery of the rotating member 20. The provided inner lining ring 23 mainly facilitates the rotation of the housing 22. A plurality of penetrating second guide portions 202 are further arranged on the rotating member 20. One of the plurality of second guide portions 202 is also set as elongated, penetrating slot, but it is arranged along the outer circumference of the rotating member 20 without inclination, solely for limiting the rotation of one of the plurality of second guide portions 202. A plurality of limiting pins capable of moving in one of the plurality of second guide portions 202 are arranged on the inner lining ring 23. The movement of the limiting pins within one of the plurality of second guide portions 202 primarily serves to restrict the rotation range of the rotating member 20.

[0039] An outer circumference of the inner lining ring 23 is fixedly provided with a housing 22, the housing 22 and the combustion chamber 10 are fixed to each other, and one of the plurality of first air inlets 101 is completely covered. The housing 22 is mainly used to isolate the air delivered by the air inlet assembly 26 from the outside, ensuring that all incoming air can enter the combustion chamber 10 through one of the plurality of first air inlets 101 and one of the plurality of second air inlets 114 to participate in combustion.

[0040] As shown in FIGS. 1, 2, and 4, as a preferred mode of the above embodiment, it further comprises a sealing cover 24 arranged on the outer side of the combustion chamber 10 and covering the ignition disk 11 and one of the plurality of movable pins 12. The sealing cover 24 is tubular-shaped, and the housing 22 and the sealing cover 24 are mutually sealed and fixedly arranged. A sealing cap 25 is fixedly arranged at a front end of the sealing cover 24. The driving assembly 27 is arranged on a front end face of the sealing cap 25. An air inlet assembly 26 for supplying air into the sealing cover 24 is fixedly arranged on the sealing cap 25, and a fan blade of the air inlet assembly 26 is coated with a coating for preventing electrostatic adsorption of dust. The applied coating is an organic substance coated onto the blade, which can utilize the attachment effect to effectively address the issues of dust erosion and the influence of frictional electric field forces on the blade surface; thereby enhancing motor lifespan and volumetric efficiency.

[0041] As a preferred embodiment of the above embodiment, a heat exchanger assembly 28 is sleeved on the outer side of the combustion chamber 10. The heat exchanger assembly 28 and the sealing cover 24 are fixed to each other. Specifically, the housing 22 is fixed between the sealing cover 24 and the heat exchanger assembly 28. Moreover, an exhaust pipe 29 facilitating exhaust of the combustion chamber 10 is arranged in the heat exchanger assembly 28. The heat exchanger assembly 28 primarily contains water, which is circulated using a water pump. The water in the heat exchanger assembly 28 carries away the generated combustion heat for utilization.

[0042] The specific working principle of the present disclosure is as follows: The air inlet assembly 26 is activated to introduce external air, which is then delivered into the combustion chamber 10 through one of the plurality of second air inlets 114 and one of the plurality of first air inlets 101 for combustion. The feeding pipe 112 introduces fuel into one of the plurality of volatilization nets 115, where it volatilizes and mixes with air. After the igniter 113 ignites, the fuel is ignited and generates heat. The water flowing in the heat exchanger assembly 28 absorbs the generated heat and carries it away for utilization; when used in a dusty environment and dust removal is required, the driving assembly 27 is activated. The driving assembly 27 drives the main shaft 18 to rotate. As the main shaft 18 rotates, it drives the first toggle member 181 to rotate. The first toggle member 181 toggles the second toggle member 193 to rotate. The second toggle member 193 drives the movable ring 19 to rotate, which synchronously drives the rotating member 20 to rotate. As the rotating member 20 rotates, it drives the first ferrule 13 to rotate, causing one of the plurality of cleaning members 132 and the scraper blade 133 to extend into one of the plurality of first air inlets 101 to clean it; during the continuous rotation of the main shaft 18, the rotating member 20, limited by one of the plurality of limiting pins on the inner lining ring 23, cannot continue to rotate. At this point, the first toggle member 181 continues to toggle the second toggle member 193 to rotate. The guide pin 192, guided by the first guide portion 201, moves in a direction away from the main shaft 18 until the first toggle member 181 and the second toggle member 193 are completely separated. Afterwards, under the tension of the reset member 21, the rotating member 20 and the first ferrule 13 rotate in reverse to reset; and the main shaft 18 continues to rotate, driving the push head 17 to move towards one side of the connecting plate 14, thereby pushing the connecting plate 14 and one of the plurality of movable pins 12 to move. This causes one of the plurality of movable pins 12 to extend into one of the plurality of second air inlets 114 to clean the dust inside. Therefore, during each cleaning process, the cleaning of one of the plurality of first air inlets 101 and one of the plurality of second air inlets 114 is separated to avoid simultaneous cleaning. This prevents air from being blocked and unable to enter the combustion chamber 10 for combustion, which could lead to flame interruption. Additionally, the plurality of second air inlets 114 are positioned corresponding to one of the plurality of volatilization nets 115, allowing for more uniform mixing of fuel and air, reducing incomplete combustion, and thereby reducing carbon deposits from combustion in the combustion chamber 10.
