Description

Technical Field

[0001] This utility model relates to the field of cold fog machines, specifically to a dual-heating coil type cold fog machine. Background Technology

[0002] Cold fogging machines are agricultural and forestry plant protection machinery widely used for pest control, disinfection, sterilization, and fertilization. Cold fogging machines include fogging machines and steam-type cold fogging machines. Steam-type cold fogging machines 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-type cold fogging machines are smaller and lighter than fogging machines, making them more widely used.

[0003] Traditional cold foggers only have heating coils for the adjuvants, resulting in low heating efficiency and insufficient pressure of the adjuvants after heating, leading to poor atomization of the pesticide solution. Furthermore, the low air pressure also results in a short spraying distance, significantly reducing the efficiency of pesticide spraying in agricultural activities. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned traditional technology and provide a dual-heating coil type cold fog machine with a double coil superimposed heating agent.

[0005] The objective of this utility model is achieved through the following technical measures:

[0006] A dual-heating coil type cold fogger, characterized in that: it includes a fixed mounting plate, a heater is fixedly connected to one side of the fixed mounting plate, a heating cylinder is fixedly connected to the other side of the fixed mounting plate, a heating assembly is connected to the heating cylinder, a dual-coil assembly is sleeved inside the heating cylinder, the dual-coil assembly includes a first heating coil and a second heating coil, the first heating coil and the second heating coil are stacked alternately, both the first heating coil and the second heating coil are spiral structures with a certain taper, the output ends of the first heating coil and the output ends of the second heating coil are fixedly connected to the same coil merging connecting pipe, the output end of the coil merging connecting pipe is fixedly connected to an output straight pipe, the output straight pipe is fixedly connected to a nozzle, and a liquid input pipe is connected to the side of the nozzle.

[0007] As an improvement: the dual-coil assembly includes a first input tube and a second input tube, the first input tube being connected to a first heating straight tube, and the second input tube being connected to a second heating straight tube.

[0008] As an improvement: the first heating straight tube is fixedly connected to the first heating coil, the second heating straight tube is fixedly connected to the second heating coil, and the first heating straight tube and the second heating straight tube are arranged in parallel.

[0009] As an improvement: a heating sleeve is sleeved at the end of the heating cylinder, and the output ends of the first heating coil and the second heating coil are both disposed through the heating sleeve, and the first heating straight tube and the second heating straight tube are disposed through the heating sleeve.

[0010] As an improvement: the heating assembly includes a limiting ring, which is fixedly connected to the inner wall of the heating cylinder. The limiting ring and the heater form a combustion chamber, and the limiting ring and the heating cylinder form a heating chamber.

[0011] As an improvement: a spark plug for ignition is fixedly connected to the outside of the heating cylinder, and the spark plug is located outside the combustion chamber.

[0012] Due to the adoption of the above technical solution, the advantages of this utility model compared with the prior art are:

[0013] By using stacked and interlaced first and second heating coils, the heating efficiency of the additives within the first and second heating coils can be increased. This ensures sufficient heating without replacing the heaters, improving the heating speed and quantity of the additives and thus increasing heating efficiency. The coil merging and connecting pipes can integrate the additives heated in the first and second heating coils. On one hand, this allows the vaporized additives to provide more continuous pressure, thus propelling the liquid medicine further through the nozzle. On the other hand, it also pressurizes the vaporized additives, resulting in finer and smaller atomized particles, enhancing the atomization effect of the liquid medicine.

[0018] Example: Figures 1 to 3 The illustrated dual-heating coil type cold fogger includes a fixed mounting plate 1. A heater 2 is fixedly connected to one side of the fixed mounting plate 1, and a heating cylinder 3 is fixedly connected to the other side of the fixed mounting plate 1. A heating assembly 4 is connected to the heating cylinder 3. A dual-coil assembly 6 is sleeved inside the heating cylinder 3. The dual-coil assembly 6 includes a first heating coil 65 and a second heating coil 66, which are stacked alternately. Both the first heating coil 65 and the second heating coil 66 are spiral structures with a certain taper. The output ends of the first heating coil 65 and the second heating coil 66 are fixedly connected to the same coil merging connecting pipe 67. The output end of the coil merging connecting pipe 67 is fixedly connected to an output straight pipe 68. A nozzle 7 is fixedly connected to the output straight pipe 68, and a liquid input pipe 8 is connected to the side of the nozzle 7.

[0019] By staggering the first heating coil 65 and the second heating coil 66, heat leakage can be effectively prevented, allowing the heat generated by the heater 2 to more effectively heat the first heating coil 65 and the second heating coil 66, improving heating efficiency, promoting the vaporization of the additives, and increasing the pressure of the vaporized additives. The coil merging connecting pipe 67 can effectively integrate the high-temperature additives generated by the first heating coil 65 and the second heating coil 66, increasing the output of the additives on the one hand, ensuring the spraying distance of the liquid medicine, and increasing the pressure of the additives on the other hand, ensuring the full atomization of the liquid medicine and improving the atomization efficiency of the liquid medicine.

[0020] The dual-coil assembly 6 includes a first input pipe 61 and a second input pipe 62. The first input pipe 61 is connected to a first heating straight pipe 63, and the second input pipe 62 is connected to a second heating straight pipe 64. The first heating straight pipe 63 is fixedly connected to a first heating coil 65, and the second heating straight pipe 64 is fixedly connected to a second heating coil 66. The first heating straight pipe 63 and the second heating straight pipe 64 are arranged in parallel. The first input pipe 61 and the second input pipe 62 allow for the separate input of additives to supply liquid to the first heating straight pipe 63 and the second heating straight pipe 64. The first heating straight pipe 63 and the second heating straight pipe 64 enable the rapid delivery of additives requiring heating to the highest-temperature heating section.

[0021] A heating sleeve 5 is fitted onto the end of the heating cylinder 3. The output ends of the first heating coil 65 and the second heating coil 66 both pass through the heating sleeve 5. The first heating straight tube 63 and the second heating straight tube 64 also pass through the heating sleeve 5. The heating sleeve 5 serves two purposes: it prevents heat loss from the heating chamber 43 and it facilitates the installation and positioning of the dual-coil assembly 6.

[0022] The heating assembly 4 includes a limiting ring 41, which is fixedly connected to the inner wall of the heating cylinder 3. The limiting ring 41 and the heater 2 together form a combustion chamber 43, and the limiting ring 41 and the heating cylinder 3 together form a heating chamber 42. The limiting ring 41 can limit the position of the dual-coil assembly 6, ensuring sufficient space within the combustion chamber 43 to achieve complete combustion and thus provide sufficient heat for heating the additives.

[0023] A spark plug 44 for ignition is fixedly connected to the outside of the heating cylinder 3, and the spark plug 44 is located outside the combustion chamber 43. The spark plug 44 enables ignition and combustion within the combustion chamber 43, ensuring continuous combustion and improving heating efficiency.
