Description

Technical Field

[0001] The utility model relates to the technical field of nozzles, in particular to an adjustable spray device. Background Art

[0002] During the cigarette processing process, it is necessary to spray spices on the tobacco leaves of the cigarettes. The cigarette spices used today are in liquid form. If the spices need to be sprayed evenly on the cigarettes, an atomizing nozzle needs to be used to atomize the liquid spices so that the atomized spices can fall evenly on the spices.

[0003] During the atomization process, the nozzles under the existing technology can only mix a fixed proportion of compressed air into the spices during the atomization process, and cannot adjust the mixing ratio between the compressed air and the spices, resulting in a relatively single atomization degree of the spices. It cannot be used on cigarette production lines with different atomization degrees. Different cigarette production lines need to be equipped with nozzles with different atomization capabilities, which will increase procurement costs. If the atomization degree needs to be adjusted, the nozzle needs to be replaced, and disassembling the nozzle will reduce production efficiency. Utility Model Content

[0025] Under existing technology, during the cigarette production process, the nozzle impacts high-pressure gas onto the liquid, which is also the flavoring, so that the liquid is dispersed into an atomized state. However, the ratio between the high-pressure gas and the liquid is constant and cannot be flexibly adjusted. The concentration of the atomized flavoring cannot be flexibly adjusted according to production needs. Only different types of nozzles can be replaced, and disassembly and assembly are time-consuming, which reduces production efficiency.

[0026] In order to solve the above problems, Figures 1 to 5 As shown, the present invention provides an adjustable spray device, including a shell 1, a connecting portion 2, a nozzle 3 and a cover 4. The shell 1 is connected to the nozzle 3 through the connecting portion 2. The nozzle 3 is provided with a nozzle 31. The shell 1 is provided with a liquid inlet 11. A sleeve pipe 5 is installed in the connecting portion 2. A sleeve cavity 12 is formed in the shell 1. The liquid inlet 11 is connected to the sleeve cavity 12 through the sleeve pipe 5. A valve core 6 is installed in the sleeve cavity 12. The end of the valve core 6 abuts on the output end 51 of the sleeve pipe 5. The output end 51 is inserted into the nozzle 31. The shell 1 is provided with a first An air hole 13, the valve core 6 is sleeved with the piston 7, the side of the piston 7 abuts on the first air hole 13, the gas in the first air hole 13 pushes the piston 7 to move, and the piston 7 drives the valve core 6 to move, a jet port 33 is provided on the nozzle 3, a second air hole 14 is provided on the shell 1, the second air hole 14 is connected to the jet port 33, the cover body 4 is installed on the side of the shell 1 away from the nozzle 3, and a first spring 8 and a second spring 9 are installed in the cover body 4, the first spring 8 abuts on the side of the piston 7 away from the first air hole 13, and the second spring 9 connects the valve core 6 and the cover body 4.

[0027] The gas entering the first and second air holes 13 and 14 originate from independent sources. The higher pressure of the gas entering the first air hole 13 pushes the piston 7 to compress the first spring 8, causing it to move. The piston 7 pushes the inner valve core 6 to move, allowing the gap between the valve core 6 and the output end 51 to be flexibly adjusted. Liquid fragrance entering through the liquid inlet 11 flows along the sleeve cavity 12 and the sleeve tube 5, ultimately being ejected from the output end 51. The gap between the valve core 6 and the output end 51 can be flexibly adjusted by the gas pressure within the first air hole 13. A larger gap increases the proportion of fragrance in the atomized gas, while a smaller gap decreases the proportion of fragrance in the atomized gas. This allows the proportion of fragrance to be flexibly adjusted by the gas pressure within the first air hole 13, making the adjustable spray device more adaptable. The second air hole 14 receives compressed gas from the outside, causing the compressed gas to be ejected from the jet port 33, where it impacts the fragrance liquid ejected from the output end 51, atomizing the fragrance liquid. The shell 1, the connecting portion 2, the nozzle 3 and the cover 4 are connected together by threads, which facilitates disassembly and maintenance.

[0028] When the adjustable spray device stops working, the first spring 8 pushes the piston 7 back to its original position, and the second spring 9 pushes the valve core 6 to abut against the output end 51 to prevent the fragrance liquid from spraying out of the output end 51. The reset function is achieved by the first spring 8 and the second spring 9.

[0029] The circumferential protrusion of the valve core 6 forms a limiting edge 61, which abuts against the side of the piston 7. The raised limiting edge 61 is easily pushed by the piston 7, so that the air in the first air hole 13 can flexibly push the valve core 6 to move.

[0030] An adjusting rotary part 70 is also screwed into the liquid inlet hole 11. The adjusting rotary part 70 is installed on the side wall of the shell 1. The plug-in part at the lower end of the adjusting rotary part 70 is plugged into the liquid inlet hole 11. A throttle hole is formed on the plug-in part. If the axis of the throttle hole coincides with the axis of the liquid inlet hole 11, the flow rate of the liquid inlet hole 11 will increase. If the throttle hole rotates with the plug-in part, the flow rate of the fragrance entering the shell 1 will be limited. The flow rate of the fragrance liquid entering the shell 1 can be manually adjusted by adjusting the rotating part 70.

[0031] The outer circumference of the piston 7 is recessed inward to form a groove, in which a first sealing ring 10 is sleeved. The first sealing ring 10 can prevent the fragrance liquid in the sleeve cavity 12 from entering the cover body 4, and prevent the fragrance from leaking to the side of the first spring 8 and the second spring 9 during the repeated movement of the piston 7.

[0032] The cover 4 is screwed onto one side of the housing 1 by means of threads, which facilitates subsequent maintenance and inspection or replacement of the internal valve core 6 and reduces maintenance difficulty.

[0033] A knob 20 is screwed onto the cover body 4, and the second spring 9 connects the knob 20 and the valve core 6. The knob 20 moves along the axis of the valve core 6. During the rotation of the knob 20, it will move along its own axis, thereby changing the compression amount of the second spring 9, so that the pressure applied to the valve core 6 by the second spring 9 changes, and then the force required for the valve core 6 to be pushed by the piston 7 can be adjusted, and the critical value required to open the valve core 6 can be adjusted. It can be flexibly adjusted according to the injection pressure required by different production lines.

[0034] Two groups of raised portions 32 are formed on the nozzle 3, and the raised portions 32 are arranged opposite to each other. Air jets 33 are opened on the raised portions 32. The nozzle 3 is cylindrical, and the air jets 33 are directed toward the axis of the nozzle 3. The air ejected from the air jets 33 will directly spray the liquid ejected from the nozzle 31, so that the liquid can be blown away by the air ejected from the air jets 33, so that the fragrance liquid can be atomized. The compressed air is blown out from opposite sides respectively, so that the liquid can be evenly dispersed, thereby improving the atomization ability.

[0035] An air-guiding gap 30 is formed between the sleeve 5 and the connecting portion 2, and an auxiliary gap 40 is formed between the output end 51 and the nozzle 31. The second air hole 14 communicates with the auxiliary gap 40 through the air-guiding gap 30, allowing the auxiliary gap 40 to eject gas outward. The air-guiding gap 30 is connected to the air jet port 33. The output gap is provided circumferentially around the nozzle 31 to help break up the fragrance liquid ejected from the nozzle 31, thereby achieving a higher degree of atomization of the fragrance liquid.

[0036] A first pipeline 21 and a second pipeline 22 are provided on the connecting portion 2. The first pipeline 21 is connected to the air guide gap 30, and the air entering from the second air hole 14 outside is introduced into the first pipeline 21. The second pipeline 22 is provided on the side wall of the first pipeline 21. The second pipeline 22 is connected to the jet port 33. A throttling column 50 is inserted into the first pipeline 21, and the throttling column 50 rotates along its own axis. A first opening 501 is provided on the side wall of the throttling column 50, and a guide tube 502 is provided in the throttling column 50. The first opening 501 is connected to the air guide gap 30 through the guide tube 502. By rotating the throttle column 50, the larger the area of ​​overlap between the first opening 501 and the second pipeline 22, the higher the flow rate of high-pressure gas passing through will be. Conversely, the smaller the area of ​​overlap between the first opening 501 and the second pipeline 22, the smaller the flow rate of high-pressure gas passing through will be. By rotating the throttle column 50 in the first pipeline 21, the size of the jet can be flexibly adjusted, and thus the atomization ratio can be flexibly adjusted.

[0037] A rotating nut 60 is installed at the top of the throttling column 50, and a marking area 601 is provided on the rotating nut 60. The marking area 601 is oriented in the same direction as the first opening 501. When the marking area 601 is directed toward the side of the nozzle 31, the first opening coincides with the axis of the second pipeline 22, and the gas flow rate reaches a maximum. By setting the marking area 601, the gas flow rate can be intuitively adjusted.

[0038] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
