Description

Technical Field

[0001] This utility model relates to a liquid spray nozzle for a cold fogging machine, specifically, to a dual atomizing nozzle. Background Technology

[0002] Cold fogging machines are widely used for pest and disease control and efficient fertilizer application in crops such as cotton, wheat, rice, and corn, greenhouse crops, fruit trees, forests, and tea gardens. However, fogging machines are no longer limited to pest and disease control and fertilization in agriculture, forestry, greenhouse fruit trees, etc. They are also widely used in urban sanitation, animal husbandry, mosquito control, biological control of disease vectors such as flies and cockroaches, warehousing and logistics, grain and oil food processing plants, garbage and sewage treatment plants, large-scale disease control and prevention, and disinfection and sterilization in public places.

[0003] The nozzles used in existing cold fogging machines have a simple structure. They atomize the liquid medicine by spraying it out through the pressure generated by the vaporization of the additive after heating. However, due to the heating efficiency of the additive, the diffusion range of the sprayed liquid medicine is small and the atomization effect is poor, which affects the spraying area of ​​the cold fogging agent and reduces the work efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned traditional technologies and provide a dual atomizing nozzle that can perform dual atomization diffusion of liquid medicine.

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

[0006] A dual atomizing nozzle, characterized in that: it includes a straight nozzle tube, one end of which is fixedly connected to an inverted conical nozzle tube, a first atomizing component is connected inside the straight nozzle tube, a second atomizing component is connected inside the inverted conical nozzle tube, a medicine tube connector is fixedly connected to the outside of the straight nozzle tube, a medicine input tube is connected to the medicine tube connector, and a heating coil is connected to the other end of the straight nozzle tube.

[0007] As an improvement: the inner side of the straight nozzle tube forms a liquid atomization chamber, the inner side of the inverted cone nozzle tube forms a diffusion atomization chamber, the second atomization component is disposed in the diffusion atomization chamber, and the diffusion atomization chamber is connected to the liquid atomization chamber.

[0008] As an improvement: the first atomizing component includes a first atomizing nozzle, the first atomizing nozzle has a first atomizing hole, the first atomizing hole and one end of the straight nozzle tube form a coil connecting cavity, the coil connecting cavity and the liquid atomizing cavity are connected through the first atomizing hole.

[0009] As an improvement: the second atomizing component includes a cone block fixing crossbar, which is fixedly connected to the inverted cone nozzle tube, and a second atomizing cone block is fixedly connected to the lower surface of the cone block fixing crossbar.

[0010] As an improvement: the second atomizing cone and the inverted cone nozzle tube form a second atomizing chamber, and the second atomizing chamber is connected to the liquid atomizing chamber.

[0011] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0012] The first atomizing component utilizes a first atomizing nozzle to pressurize and atomize the additives heated by the heating coil. After entering the liquid atomizing chamber, the atomized additives impact and atomize the liquid input through the liquid input pipe, achieving the first liquid atomization. The liquid after the first atomization is propelled by the additives and impacts the second atomizing cone. Under the action of the cone surface of the second atomizing cone, the liquid after the first atomization enters the second atomizing chamber. The gaps within the second atomizing chamber itself further pressurize and atomize the liquid. The liquid after two atomizations exhibits a better atomization effect. Furthermore, under the action of the inverted cone nozzle and the second atomizing cone, the liquid after two atomizations can achieve a larger liquid spraying range, significantly improving the liquid spraying efficiency.

[0018] Example: As attached Figures 1 to 4As shown, a dual atomizing nozzle includes a straight nozzle tube 1, one end of which is fixedly connected to an inverted cone nozzle tube 2. A first atomizing component 3 is connected inside the straight nozzle tube 1, and a second atomizing component 4 is connected inside the inverted cone nozzle tube 2. A medicine tube connector 5 is fixedly connected to the outside of the straight nozzle tube 1, and a medicine inlet tube 6 is connected to the medicine tube connector 5. The other end of the straight nozzle tube 1 is connected to a heating coil 7.

[0019] The inner side of the straight nozzle tube 1 forms a liquid atomization chamber 8, and the inner side of the inverted cone nozzle tube 2 forms a diffusion atomization chamber 9. The second atomization component 4 is disposed within the diffusion atomization chamber 9, and the diffusion atomization chamber 9 is connected to the liquid atomization chamber 8. The liquid atomization chamber 8 atomizes the additives heated in the heating coil 7 after the liquid is sprayed out. After the liquid enters the liquid atomization chamber 8 through the liquid inlet pipe 6, the heated additives are rapidly dispersed and atomized, and then, propelled by subsequent additives, enter the diffusion atomization chamber 9.

[0020] The first atomizing component 3 includes a first atomizing nozzle 31, and a first atomizing hole 32 is provided in the first atomizing nozzle 31. The first atomizing hole 32 and one end of the straight nozzle tube 1 form a coil connecting cavity 33. The coil connecting cavity 33 and the liquid atomizing cavity 8 are connected through the first atomizing hole 32.

[0021] The first atomizing nozzle 31 can effectively increase the injection pressure of the adjuvant and improve the atomization effect of the liquid medicine. After the heated adjuvant passes through the first atomizing hole 32, it is pressurized and then quickly enters the liquid medicine atomization chamber 8. The high-pressure adjuvant can atomize the liquid medicine for the first time.

[0022] The second atomizing component 4 includes a cone-shaped fixing crossbar 41, which is fixedly connected to the inverted cone nozzle pipe 2. A second atomizing cone 42 is fixedly connected to the lower surface of the cone-shaped fixing crossbar 41. The second atomizing cone 42 and the inverted cone nozzle pipe 2 form a second atomizing chamber 43, which is connected to the liquid atomizing chamber 8. The second atomizing cone 42 can separate the diffusion atomizing chamber 9, thus forming the second atomizing chamber 43. After the first atomization, the liquid medicine enters the second atomizing chamber 43 to both sides under the action of the cone surface of the second atomizing cone 42. The gaps in the second atomizing chamber 43 pressurize the atomized liquid medicine again, realizing the second atomization of the liquid medicine.
