[0002] Foggers, also known as thermal foggers, smoke cannons, and pesticide sprayers, are a type of crop protection and pest control machinery. They utilize the pulse jet engine principle and are used for insecticides, disinfectants, sterilizers, or fertilization. Existing foggers operate on the same principle: cold foggers incorporate a heating element that heats a stored liquid to boiling. The high temperature rapidly evaporates the liquid into steam, generating thrust that atomizes and sprays the liquid.

[0003] The patent application number is: CN202323176624.2, which discloses an insulated combustion chamber tube, which includes a combustion tube, a fire-resistant insulation layer is provided on the inner wall of the combustion tube, and a water inlet pipe connected to the inner coil assembly inside the combustion tube is provided on the combustion tube. It belongs to the field of smoke machines or cold fog machines, and specifically discloses the heating element of the smoke machine or cold fog machine.

[0004] The existing smoke machine has the following problems during use:

[0005] Even if the heating elements of existing smoke machines are insulated with insulation materials, it is still difficult for the heat of the heating elements to dissipate actively after long-term use. The heat will still accumulate on the heating elements, causing the surface temperature of the smoke machine to be very high. Touching the smoke machine during operation may cause burns, which poses certain safety hazards. In addition, long-term high-temperature use will accelerate the aging of its components and reduce its service life.

[0006] Therefore, the surface temperature of the existing smoke machine is very high when used for a long time, and the operator may be burned during operation, which poses a certain safety hazard.

[0007] Therefore, a method is provided to increase the air intake volume in the shell and the combustion chamber by cooperating with a turbofan and a blower fan during use, which, on the one hand, promotes the full combustion of the air and fuel entering the combustion chamber, and on the other hand, the air flows through the air flow channel formed between the heating element and the shell, thereby enhancing the overall air flow efficiency. During the flow, the heat on the heating element can be blown away, which is helpful for the heat management and discharge inside the smoke machine, so as to achieve the function of rapid heat dissipation and cooling, avoid burns, and extend the service life of the smoke machine. A smoke machine with a blower is an urgent problem to be solved by the present invention. Utility Model Content

[0008] In response to the above technical problems, the purpose of the present invention is to overcome the problem that the heating element of the smoke machine in the prior art is insulated by thermal insulation material, but after long-term use, the heat of the heating element is still difficult to dissipate actively, and the heat will still accumulate on the heating element, which will cause the surface temperature of the smoke machine to be very high. Touching the smoke machine during operation will cause burns, which poses certain safety hazards. In addition, long-term high-temperature use will also accelerate the aging of its components and reduce its service life. Therefore, a smoke machine with a blower is provided, which uses a turbo fan and a blower to increase the air intake volume in the shell cover and the combustion chamber during use, on the one hand, promoting the full combustion of air and fuel entering the combustion chamber, and on the other hand, the air flows through the air flow channel formed between the heating element and the shell cover, enhancing the overall air flow efficiency. During the flow, the heat on the heating element can be blown away, which is helpful for the heat management and discharge inside the smoke machine, so as to achieve the function of rapid heat dissipation and cooling, avoid burns, and extend the service life of the smoke machine.

[0009] In order to achieve the above-mentioned purpose, the utility model provides a smoke machine with a blast, which includes: a shell, a heating element coaxially arranged inside the shell, a turbo fan arranged on the bottom of the combustion chamber of the heating element and capable of conveying air into the combustion chamber, and a blower fan spaced and coaxially arranged below the heating element and capable of conveying air into the shell and the combustion chamber.

On the other hand, part of the gas entering the interior from the bottom port of the shell enters the combustion chamber for combustion, and the other part of the gas can enter from the bottom of the shell and flow upward through the air flow channel formed between the heating element and the shell. In the process of gas flowing from bottom to top, the heat on the heating element can be blown away, thereby enhancing the overall air flow efficiency, contributing to the heat management and discharge inside the smoke machine, and realizing the function of rapid heat dissipation and cooling, thereby avoiding the operator touching the smoke machine during operation and being burned due to the long-term use of the smoke machine due to the high surface temperature.

[0018] (2) The smoke machine with air blowing provided by the present invention can dissipate heat and reduce temperature, so that it can maintain high efficiency operation even in harsh environments with high temperature and dust.

[0019] (3) During the heat dissipation and cooling process, the enhanced wind force generated by driving the blower fan to rotate can also increase the speed and force of the smoke ejected from the nozzle of the smoke machine, playing a role of supercharging, thereby increasing the distance of the smoke ejected by the smoke machine and the coverage area of ​​the sprayed smoke. It can be used for spraying pesticides or fertilizers over large areas, improving the coverage range and uniformity of the spraying.

During the flow, the heat on the heating element can be blown away, which is helpful for the heat management and discharge inside the smoke machine, so as to achieve the function of rapid heat dissipation and cooling, avoid burns, and extend the service life of the smoke machine.

[0030] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0031] like Figure 1-5 As shown, the utility model provides a smoke machine with a blast, which includes: a shell 1, a heating element 2 coaxially arranged inside the shell 1, a turbo fan 8 arranged on the bottom of the combustion chamber 3 of the heating element 2 and capable of conveying air into the combustion chamber 3, and a blower fan 5 spaced and coaxially arranged below the heating element 2 and capable of conveying air into the shell 1 and the combustion chamber 3.

[0032] In the above scheme, the outside air can be pressed into the combustion chamber 3 by the turbo fan 8 for air combustion, and the blower fan 5 is used to assist the worm fan 8 to bring the outside air into the interior from the bottom end of the shell 1. On the one hand, it is to increase the intake amount of the outside air into the shell 1 and the combustion chamber 3, so that the air and fuel entering the combustion chamber 3 are fully burned and the heating efficiency is improved. On the other hand, part of the gas entering the interior from the bottom port of the shell 1 enters the combustion chamber 3 for combustion, and the other part of the gas can be drawn out from the shell 1. The air enters the bottom of the housing 1 and flows upward through the airflow channel formed between the heating element 2 and the housing 1. As the air flows upward from the bottom, it can blow away the heat from the heating element 2, enhancing the overall air flow efficiency and facilitating heat management and discharge within the smoke machine, thereby achieving rapid heat dissipation and cooling. This prevents operators from touching the smoke machine during operation and causing burns due to excessive surface temperatures caused by prolonged use. It also prevents overheating due to prolonged operation, reduces the risk of burns and damage to the entire device due to excessive temperatures, and in severe cases, fires. This resolves the safety hazards caused by excessive temperatures throughout the device, improves the safety and reliability of the device, and also reduces the accelerated aging of the device's mechanical components due to excessive temperatures, extending the device's service life. It also reduces the need for frequent repairs or replacements of the device's mechanical components due to excessive temperatures, reducing maintenance costs.

[0033] In addition, the advantage of heat dissipation and cooling enables the entire smoke machine equipment to work effectively in different environments and a wider range of application scenarios. For example, it can maintain efficient operation even in harsh environments with high temperature and dust.

[0034] During use, the enhanced wind force generated by rotating the blower fan 5 also increases the speed and force of the smoke ejected from the nozzle 4, acting as a pressure booster, thereby increasing the spray distance and coverage area of ​​the smoke. This can be used for spraying pesticides or fertilizers over large areas, improving coverage and spraying uniformity.

[0035] Therefore, through the above advantages, the blower smoke machine can be flexibly used in different fields, such as:

[0036] In agricultural applications such as spraying pesticides or fertilizers, the wind generated by the blower fan 5 can disperse the sprayed smoke into smaller particles, further refining the droplets and improving the atomization effect of the fog machine. This further refines the smoke sprayed by the fog machine into smaller particles, which can be easily absorbed by crops. Furthermore, the refined smoke particles evaporate more quickly, reducing liquid residue on the ground, being environmentally friendly and reducing resource waste.

[0037] It can also be used in the field of public health, specifically for air disinfection or surface disinfection in public places or medical environments to improve disinfection efficiency.

[0038] It can also be used in industrial fields, specifically in industries that spray liquids or particles in large quantities and over long distances, such as material processing or environmental control.

[0039] In a preferred embodiment of the present invention, the nozzle 4 of the heating element partially extends from a port of the housing 1 , and the blower fan 5 is assembled at another port of the housing 1 through a mounting seat 6 .

[0040] In the above solution, the heating element further comprises: a combustion tube 9, an inner coil body 10, a discharge tube 11 and a water inlet tube 12, wherein:

[0041] The water inlet pipe 12 is located on the outer side of the end of the combustion tube 9 away from the combustion chamber 3, and a circulation pump is provided on the water inlet pipe 12. The inner coil body 10 is arranged inside the combustion tube 9. The discharge pipe 11 is horizontally arranged in the middle of the inner coil body 10, and one end thereof is connected to the inner coil body 10, and the other end extends out of the interior of the combustion tube 9; the connecting ends of the discharge pipe 11 and the water inlet pipe 12 are respectively located at the two opposite ends of the inner coil body 10, and a nozzle 4 is provided at the end of the discharge pipe 11 located outside the combustion tube 9, and a reagent tube is also provided on the outside of the nozzle 4.

[0042] The atomization principle of the smoke machine: the water inlet pipe 12 introduces water into the inner coil body 10 and heats the inner coil body 10 in the combustion tube 9 through the combustion chamber 3 to ensure the generation of high-temperature and high-pressure steam; the circulation pump provides the power for the water flow to ensure its smooth flow and a certain pressure. Of course, the flow rate can also be controlled to control the heating time and thus the heating temperature. The discharge pipe 11 conducts the final diversion of the generated steam to ensure its ejection pressure and smoothness. The generated high-temperature and high-pressure gas is finally discharged together with the mixed agent through the nozzle 4 to achieve the mist spraying effect of the agent.

[0043] In a preferred embodiment of the present invention, the annular mounting seat 6 is coaxially fixed in the port of the shell cover 1, and a blower fan 5 is provided on the mounting seat 6 located inside the shell cover 1, and the central rotating axis of the blower fan 5 is in the same straight line as the central axis of the mounting seat 6.

[0044] In the above solution, the blower fan 5 is assembled to the housing 1 through the mounting seat 6 , which plays a role in protecting the blower fan 5 .

[0045] In a preferred embodiment of the present invention, a handle 7 is detachably fixed on the housing 1 .

[0046] In the above solution, the handle 7 is assembled to the housing 1 in a detachable manner to facilitate subsequent maintenance and replacement.

[0047] In a preferred embodiment of the present invention, the handle 7 is assembled on the housing 1 by means of a flange seat and bolts; wherein,

[0048] A flange seat is fixedly provided on the handle 7, and a plurality of threaded holes corresponding one-to-one to the plurality of through holes on the flange seat are opened on the shell cover 1. The flange seat rests on the shell cover, and the plurality of through holes of the flange seat correspond one-to-one to the plurality of threaded holes on the shell cover. The plurality of bolts respectively pass through the plurality of through holes on the flange seat and are respectively screwed on the corresponding threaded holes.

[0049] In the above solution, the handle 7 can be detachably assembled on the housing 1 by using the flange seat and bolts, so as to simplify assembly and disassembly, thereby facilitating subsequent maintenance and replacement.

[0050] In a preferred embodiment of the present invention, a dustproof net is fixedly provided inside the mounting base 6 .

[0051] In the above solution, dust or other impurities from the outside are prevented from entering the smoke machine and affecting the normal use of the components on the smoke machine.

[0052] In summary, the smoke machine with blower provided by the utility model overcomes the problem that the heating element of the smoke machine in the prior art is insulated by thermal insulation materials. However, after long-term use, the heat of the heating element is still difficult to dissipate actively, and the heat will still accumulate on the heating element, which will cause the surface temperature of the smoke machine to be very high. Touching the smoke machine during operation will cause burns, which poses certain safety hazards. Moreover, long-term high-temperature use will accelerate the aging of its components and reduce its service life.
