AI Technical Summary
In existing sprayers, the relative position of the oil inlet pipe of the electronically controlled direct injection system and the blower results in excessively high wind speed, which affects spark plug ignition, leads to insufficient temperature in the combustion chamber, reduces working efficiency, and shortens the service life of the electronically controlled spark plug, increasing operating costs.
The design incorporates a combustion rod, which achieves cyclone-like airflow by setting up an air supply and outlet duct and an air outlet slot. Combined with an air inlet bend and a wind-limiting baffle, the air pressure is increased. A combustion rod is installed on the outside of the air outlet duct, which absorbs heat to independently ignite the fuel-air mixture, temporarily shutting off the electronically controlled spark plug and extending its service life.
This achieves continuous combustion while saving energy, extending the service life of electronic spark plugs and reducing energy consumption and operating costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural and forestry plant protection machinery, specifically to a smoke machine equipped with a combustion rod. Background Technology
[0002] Sprayers are agricultural and forestry plant protection machinery widely used for pest control, disinfection, sterilization, and fertilization. Sprayers include fogging machines and steam sprayers. Steam sprayers separate the pesticide and adjuvants, heating the adjuvants separately before mixing the room-temperature pesticide with the heated adjuvants and spraying. This ensures the effectiveness of the pesticide. Steam sprayers are smaller and lighter than fogging machines, making them more widely used.
[0003] The existing electronic direct injection system has a problematic relative position between the fuel inlet pipe and the blower. The airflow directly hitting the spark plug is too fast, leading to incomplete combustion of the fuel during injection. The direct airflow also affects spark plug ignition. Excessive airflow within the sprayer prevents proper ignition of the fuel, resulting in insufficient combustion chamber temperature and reduced heating of the fuel. All these factors reduce the sprayer's efficiency. Furthermore, prolonged operation of the electronic spark plug significantly shortens its lifespan and increases operating costs. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned traditional technologies and provide a smoke generator equipped with a combustion rod that can save energy while ensuring continuous combustion.
[0005] The objective of this utility model is achieved through the following technical measures: A smoke generator equipped with a combustion rod is characterized by comprising a fixed mounting cylinder, a fixed mounting plate fixedly connected to one side of the fixed mounting cylinder, an air inlet assembly fixedly connected to the other side of the fixed mounting cylinder, the air inlet assembly including an air supply fixing plate, an air supply outlet duct fixedly connected to one side of the air supply fixing plate, an air outlet groove formed on the side of the air supply outlet duct, an outlet duct baffle fixedly connected to the side of the air supply outlet duct away from the air supply fixing plate, a combustion rod fixedly connected to the outlet duct baffle, a heating assembly connected to the side of the fixed mounting plate away from the fixed mounting cylinder, the heating assembly including a heating fixing cylinder, a spark plug mounting seat fixedly connected to the heating fixing cylinder, an electrically controlled spark plug fixedly connected to the spark plug mounting seat by threads, the electrically controlled spark plug being positioned above the combustion rod, and a coil assembly sleeved inside the heating fixing cylinder.
[0006] As an improvement: the heating assembly includes a heating sleeve, which is sleeved with a heating fixed cylinder, and both the heating sleeve and the heating fixed cylinder are provided with exhaust ports.
[0007] As an improvement: the air intake assembly includes an air intake bend, one end of which is fixedly connected to the air supply fixing plate, the air intake bend is connected to the air supply outlet duct, the other end of which is fixedly connected to a limited air baffle, and an oil injection pipe is fixedly connected to the side of the air intake bend.
[0008] As an improvement: an air storage cover is fixedly connected to the side of the fixed mounting plate, and an air supply fan is fixedly connected to the air storage cover.
[0009] As an improvement: the coil assembly includes a heating coil, which is sleeved with a heating fixing cylinder. One end of a heating straight tube is fixedly connected to the input end of the heating coil, and an auxiliary agent input tube is fixedly connected to the other end of the heating straight tube. An atomizing nozzle is fixedly connected to the output end of the heating coil, and a liquid medicine input tube is fixedly connected to the side of the atomizing nozzle.
[0010] By adopting the above technical solution, this utility model has the following advantages compared with the prior art: By designing the air supply and outlet ducts and opening the air outlet slots, the airflow can be limited, resulting in a cyclone-like airflow. This prevents the air from directly blowing onto the electronic spark plug and causing combustion to stop. The air inlet bend and air limiting baffle increase the air pressure blowing into the air supply and outlet ducts, better achieving cyclone input. By fixing the burner rod to the outside of the air outlet baffle, the burner rod can effectively absorb heat, thereby achieving a state where it can independently ignite the fuel-air mixture. When the burner rod can independently ignite the fuel-air mixture, the electronic spark plug can be temporarily shut off, increasing the lifespan of the electronic spark plug and reducing energy consumption.

[0016] Example: Figures 1 to 4 As shown, a smoke generator equipped with a combustion rod includes a fixed mounting cylinder 1. A fixed mounting plate 2 is fixedly connected to one side of the fixed mounting cylinder 1, and an air inlet assembly 5 is fixedly connected to the other side of the fixed mounting cylinder 1. The air inlet assembly 5 includes an air supply fixing plate 51. An air supply outlet duct 52 is fixedly connected to one side of the air supply fixing plate 51. An air outlet slot 53 is opened on the side of the air supply outlet duct 52 away from the air supply fixing plate 51. An air outlet baffle 54 is fixedly connected to the air outlet baffle 54. A combustion rod 6 is fixedly connected to the air outlet baffle 54. A heating assembly 3 is connected to the fixed mounting plate 2 away from the fixed mounting cylinder 1. The heating assembly 3 includes a heating fixing cylinder 31. A spark plug mounting seat 34 is fixedly connected to the heating fixing cylinder 31. An electronically controlled spark plug 4 is fixedly connected to the spark plug mounting seat 34 by threads. The electronically controlled spark plug 4 is positioned above the combustion rod 6. A coil assembly 9 is sleeved inside the heating fixing cylinder 31. The combustion rod 6 can store excess heat and remain in a red-hot state. When the oil-gas mixture passes through the combustion rod 6, it will burn on its own, thus eliminating the need for the electronic spark plug 4 and increasing its service life.
[0017] The heating assembly 3 includes a heating sleeve 32, which is sleeved with a heating fixing cylinder 31. Both the heating sleeve 32 and the heating fixing cylinder 31 are provided with exhaust ports 33. The exhaust ports 33 allow the exhaust gases generated during combustion to be discharged.
[0018] The air intake assembly 5 includes an air intake bend 55. One end of the air intake bend 55 is fixedly connected to the air supply fixing plate 51. The air intake bend 55 is connected to the air supply outlet duct 52. The other end of the air intake bend 55 is fixedly connected to a limited air baffle 56. An oil injection pipe 57 is fixedly connected to the side of the air intake bend 55.
[0019] A storage hood 7 is fixedly connected to the side of the fixed mounting plate 2, and a supply fan 8 is fixedly connected to the storage hood 7. The supply fan 8 can blow air into the storage hood 7 and blow the air in the storage hood 7 into the air inlet bend 55.
[0020] The coil assembly 9 includes a heating coil 91, which is sleeved with a heating fixing cylinder 31. The input end of the heating coil 91 is fixedly connected to one end of a heating straight tube 92, and the other end of the heating straight tube 92 is fixedly connected to an auxiliary agent input tube 95. The output end of the heating coil 91 is fixedly connected to an atomizing nozzle 93, and the side of the atomizing nozzle 93 is fixedly connected to a liquid medicine input tube 94.
[0021] By using the air supply and outlet duct 52 and the air outlet slot 53, the airflow can be limited, making the blown air cyclone-like and preventing the air from blowing directly onto the electronic spark plug 4, thus stopping combustion. The air inlet bend 55 and the air limiting baffle 56 can increase the air pressure blown into the air supply and outlet duct 52, which can better achieve cyclone input. By fixing the combustion rod 6 on the outside of the air outlet baffle 54, the combustion rod 6 can effectively absorb heat, thereby achieving the state of independently igniting the fuel-air mixture. When the combustion rod 6 can independently ignite the fuel-air mixture, the electronic spark plug 4 can be temporarily shut off, increasing the service life of the electronic spark plug 4 and reducing energy consumption.
