Description

Technical Field

[0001] This utility model relates to a carburetor for preventing frosting in smoke machines, belonging to the technical field of anti-frosting technology for smoke machines. Background Technology

[0002] A fogging machine, also known as a misting machine, is a commonly used spraying device in agriculture, forestry, and public health. Its working principle involves using a high-temperature, high-speed airflow generated by an engine to instantly atomize liquid pesticides (insecticides, fungicides, disinfectants, etc.) into extremely fine, mist-like particles. These particles are very small in diameter (typically less than 50 micrometers), allowing them to remain suspended in the air for extended periods and diffuse and penetrate every corner of the target area, such as behind dense crop leaves, in the canopy of forests, or in concealed indoor or outdoor locations.

[0003] The structure of a fog machine from top to bottom consists of: an air filter box, a carburetor (also known as a fuel injection assembly), an upper bracket, and a lower bracket. Current solutions to the problem of frost or ice buildup on the fuel needle include adding a valve at the connection between the carburetor and the upper bracket, adding a fan to the fuel needle, or increasing the size of the air filter box to improve the insulation of the incoming air. However, none of these solutions can solve the problem of frost or ice buildup on the fuel needle.

[0004] Fog machines are susceptible to frost or ice buildup on the fuel needle due to temperature and humidity. When the temperature is below 10°C, the fog machine will stop operating after about five minutes due to frost or ice buildup on the fuel needle. When the temperature is below 7-8°C, the fog machine will stop operating after 2-3 minutes due to frost or ice buildup on the fuel needle. When the temperature is between 11-15°C, the fog machine will experience slight frost buildup. Currently, using 95-octane gasoline can extend the frost buildup time by 2-3 minutes. Fog machines cannot be used continuously; they need to be stopped for three to five minutes to completely remove the frost or ice on the fuel needle before they can be used normally again. Intermittent use leads to reduced work efficiency and higher fuel consumption. Therefore, developing a carburetor to prevent frost buildup in fog machines is crucial. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing a carburetor for preventing frosting in smoke machines.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A carburetor for preventing frost formation in a smoke machine includes a carburetor, an air inlet, and an oil needle. The air inlet is provided with an anti-frost structure for blocking the oil needle, and the anti-frost structure is located above the oil needle.

[0007] Furthermore, the anti-frost structure is made of plastic.

[0008] Furthermore, the distance between the bottom surface of the anti-frost structure and the top surface of the oil needle is 1-3mm.

[0009] Furthermore, the thickness of the anti-frost structure is greater than or equal to the diameter of the oil needle.

[0010] Furthermore, the thickness of the anti-frost structure is 1-2.4 mm.

[0011] Furthermore, when the thickness of the anti-frost structure is greater than 2.4mm, an upper bracket is detachably connected to the bottom of the carburetor, and a connecting part is formed between the upper bracket and the carburetor, with a valve provided on the connecting part.

[0012] Furthermore, the intake volume of the valve is the same as the air blocking volume of the anti-frost structure.

[0013] Furthermore, the number of valves is at least one.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the anti-frost structure of this application effectively blocks the oil needle, and the oil needle is not affected by the environment, temperature or humidity, so as to achieve continuous spraying of 30 acres of fruit trees for three hours without the oil needle frosting or freezing, thereby ensuring that the fogging machine can be used continuously without going out.

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] like Figures 1-5As shown, a carburetor for preventing frost formation in a fogging machine includes a carburetor 1, an air inlet 2, and an oil needle 3. The air inlet 2 is equipped with an anti-frost structure 4 to block the oil needle 3, and the anti-frost structure 4 is located above the oil needle 3. This application can be applied to two-cylinder, three-cylinder, or four-cylinder fogging machines. The fogging machine is connected to a backpack-style sprayer with a plastic bucket or a large agricultural bucket. While existing backpack-style sprayers require approximately ten minutes of spraying time, this application allows continuous use until the pesticide is used up. For large agricultural buckets, spraying requires more than two hours, and this application also allows continuous use until the pesticide is used up. The anti-frost structure 4 effectively blocks the oil needle 3, preventing it from being affected by environmental conditions, temperature, or humidity. This allows for continuous spraying of 30 acres of fruit trees for three hours without frost or ice formation on the oil needle 3, thus ensuring continuous operation of the fogging machine without shutting down.

[0023] The anti-frost structure 4 is made of plastic. This application effectively solves the problem of frost or ice formation on the oil needle 3 by utilizing the non-heat-conducting properties of plastic.

[0024] The distance between the bottom surface of the anti-frost structure 4 and the top surface of the oil needle 3 is 1-3mm. The smaller the distance between the bottom surface of the anti-frost structure 4 and the top surface of the oil needle 3, the more effectively the air entering through the air inlet 2 can be prevented from contacting the oil needle 3, thus more effectively preventing the oil needle 3 from frosting or freezing.

[0025] The thickness of the anti-frost structure 4 is greater than or equal to the diameter of the oil needle 3.

[0026] The thickness of the anti-frost structure 4 is 1-2.4 mm.

[0027] When the thickness of the anti-frost structure 4 is greater than 2.4mm, an upper bracket 5 is detachably connected to the bottom of the carburetor 1. A connecting part 7 is located between the upper bracket 5 and the carburetor 1, and a valve 6 is provided on the connecting part 7. If the thickness of the anti-frost structure 4 is greater than 2.4mm, it will affect the air intake volume of the air inlet 2, resulting in insufficient power in the vaporizer. By adding a valve 6 to the connecting part 7 to compensate for the obstructed air volume, the problem of insufficient power can be effectively avoided.

[0028] The air intake volume of valve 6 is the same as the air blocking volume of anti-frost structure 4. Valve 6 is used to supplement the same amount of air to ensure the power of the fog machine.

[0029] The number of valves 6 is at least one. The number of valves 6 can be increased according to actual needs.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
