Description

Technical Field

[0001] The present application relates to a nozzle, and in particular to an anti-drip and ejector-type dual-medium spraying mechanism. Background Art

[0002] At present, the flavoring process in the tobacco leaf conditioning process is achieved by using a dual-medium nozzle. The atomization of flavors and fragrances by this dual-medium nozzle is realized at the nozzle orifice by means of the pressure of compressed air, which is called external mixing. The atomization degree and spraying area of flavors and fragrances can be adjusted by changing the gap between the nozzle orifice and the nozzle core.

[0054] In the present application, when it is described that a specific component is located between a first component and a second component, there may or may not be an intermediate component between the specific component and the first component or the second component. When it is described that a specific component is connected to other components, the specific component may be directly connected to the other components without an intermediate component, or may not be directly connected to the other components and have an intermediate component.

[0055] All terms used in this application (including technical or scientific terms) have the same meaning as understood by those of ordinary skill in the art to which this application pertains, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such herein.

[0056] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the specification.

[0057] As Figures 1 to 10 shown, an embodiment of the present application provides an anti-drip injection-type dual-medium spraying mechanism, which includes a cylinder 1, a push rod 2, a material chamber 3, a material-gas mixing pipe 8, a first sealing ring, a second sealing ring, and an external nozzle 6; wherein, the push rod 2 is connected to the piston rod of the cylinder 1, an air passage is provided in the push rod 2, an injection hole is provided on the push rod 2, and the injection hole is communicated with the air passage; a storage space 32 is provided in the material chamber 3; the material-gas mixing pipe 8 is arranged in the storage space 32, a material-gas space is provided in the material-gas mixing pipe 8, a through hole 81 is provided on the material-gas mixing pipe 8, the material-gas mixing pipe 8 is communicated with the storage space 32 through the through hole 81, and one end of the push rod 2 provided with the injection hole movably penetrates into the material-gas space; the first sealing ring and the second sealing ring are arranged at intervals on the side wall of the material-gas space; the external nozzle 6 is communicated with the material-gas mixing pipe 8.

[0058] During the production process, flavors and fragrances can be input into the storage space 32 in the material chamber 3, and at the same time, the air passage in the push rod 2 is connected to an external air source to convey compressed air into the air passage. Specifically, an air hole 21 can be provided on the push rod 2, and the air hole 21 can be connected to the external air source through a pipeline. The cylinder 1 is started, and the piston rod of the cylinder 1 moves in the direction of retracting into the cylinder 1, so as to pull the push rod 2 to move in the direction of the cylinder 1. The injection hole on the push rod 2 is located between the first sealing ring and the second sealing ring, and the injection hole is not blocked by the first sealing ring or the second sealing ring. Compressed air can be output from the injection hole into the material-gas space in the material-gas mixing pipe 8, so that the area between the external nozzle 6 and the internal nozzle in the material-gas mixing pipe 8 forms a negative pressure area relative to the storage space 32, so that the flavors and fragrances in the storage space 32 can enter the material-gas mixing pipe 8 through the through hole 81 on the material-gas mixing pipe 8, so as to fully mix the flavors and fragrances through compressed air, and further spray them out through the external nozzle 6.

[0059] At the end of production, the piston rod can be extended by the cylinder 1 to push the push rod 2 to move away from the cylinder 1. When the ejection hole on the push rod 2 is blocked by the first sealing ring, the push rod 2 can block the through hole 81 on the material-gas mixing pipe 8, and the cylinder 1 stops operating. At this time, the essence and spices in the storage space 32 cannot enter the material-gas mixing pipe 8, thus avoiding the dripping phenomenon of the liquid material from the material-gas mixing pipe 8.

[0060] Therefore, compared with the prior art, the anti-dripping ejection type dual-medium spraying mechanism provided by the embodiment of the present application realizes the ejection or blocking of essence and spices through the sliding fit between the push rod 2 and the material-gas mixing pipe 8, and realizes the avoidance of the dripping phenomenon of the liquid material from the material-gas mixing pipe 8 after the production is completed.

[0061] Furthermore, the anti-dripping ejection type dual-medium spraying mechanism further includes a gland 31, which is fixedly arranged at the opening of the material cavity 3 to seal the storage space 32. The gland 31 is provided with a feed inlet 311, and the storage space 32 is connected to the feeding device through the feed inlet 311.

[0062] Wherein, a third sealing ring is arranged in the gland 31. After the gland 31 is fixed on the material cavity 3, the third sealing ring can ensure the sealing performance of the storage space 32 and prevent the liquid material from leaking out.

[0063] Furthermore, a discharge port 312 can also be arranged on the gland 31 to facilitate the recovery of the liquid material in the storage space 32, so as to realize the connection and fixation between the cylinder 1 and the material cavity 3.

[0064] Furthermore, the spraying mechanism further includes a support pipe 11, and both ends of the support pipe 11 are fixedly connected to the fixed part of the cylinder 1 and the gland 31 respectively.

[0065] Furthermore, to ensure the reliability of the fixation of the material-gas mixing pipe 8 in the material cavity 3, the material-gas mixing pipe 8 is threadedly connected to the material cavity 3. At the same time, the threaded connection can ensure the sealing performance between the material-gas mixing pipe 8 and the material cavity 3.

[0066] Furthermore, the anti-dripping ejection type dual-medium spraying mechanism can also include a connecting body 7, the connecting body 7 is threadedly connected to the material-gas mixing pipe 8, and the outer nozzle 6 is fixedly arranged on the connecting body 7.

[0067] After the connecting body 7 is fixed to the material-gas mixing pipe 8, the outer nozzle 6 can extend into the material-gas mixing pipe 8 to make the outer nozzle 6 communicate with the material-gas mixing pipe 8, so that the mixed essence and spices can be ejected from the outer nozzle 6.

[0068] Further, the anti-drip ejector double-medium spraying mechanism may further include an upper clamping plate 4 and a lower clamping plate 5. A first positioning hole is provided on the upper clamping plate 4, and a second positioning hole is provided on the lower clamping plate 5. The outer wall surface of the material cavity 3 is spherical, and the material cavity 3 is arranged between the upper clamping plate 4 and the lower clamping plate 5. The outer wall of the material cavity 3 abuts against the first positioning hole and the second positioning hole respectively.

[0069] It can be understood that in order to enable the material cavity 3 to be clamped on the first positioning hole and the second positioning hole, the maximum diameter of the material cavity 3 is larger than that of the first positioning hole and the second positioning hole. Thus, the two parts on both sides of the position with the largest diameter on the material cavity 3 can be respectively clamped on the first positioning hole and the second positioning hole. Therefore, the material cavity 3 can be firmly clamped and fixed by the cooperation of the upper clamping plate 4 and the lower clamping plate 5.

[0070] Further, the upper clamping plate 4 is provided with a first positioning hole and more than two first fixing holes 41. The first fixing holes 41 are arranged around the first positioning hole. The lower clamping plate 5 is provided with a second positioning hole and more than two second fixing holes 51. The second fixing holes 51 are arranged around the second positioning hole, and the second fixing holes 51 cooperate with the first fixing holes 41.

[0071] After the material cavity 3 is clamped between the upper clamping plate 4 and the lower clamping plate 5, the first fixing holes 41 and the second fixing holes 51 can be aligned, and the relative fixation of the upper clamping plate 4 and the lower clamping plate 5 can be realized through the cooperation of bolts and the first fixing holes 41 and the second fixing holes 51. Thus, the material cavity 3 can be stably clamped and fixed between the upper clamping plate 4 and the lower clamping plate 5.

[0072] When it is necessary to change the spraying direction of the external nozzle 6 on the material cavity 3, the bolts fixed in the first fixing holes 41 and the second fixing holes 51 can be loosened to release the clamping of the material cavity 3, so that the material cavity 3 can rotate an appropriate angle to adjust the spraying direction of the external nozzle 6. After the spraying direction is adjusted, the bolts can be tightened again in the first fixing holes 41 and the second fixing holes 51 to realize the relative fixation of the upper clamping plate 4 and the lower clamping plate 5, thereby locking the adjustment state of the material cavity 3.

[0073] Therefore, without changing the structure of the external nozzle 6 and without disassembling the external nozzle 6, the spraying direction of the essence and flavor can be adjusted by rotating and adjusting the material cavity 3, thus meeting the requirement of spraying spices in different directions.

[0074] Further, the inner wall surfaces of the first positioning hole and the second positioning hole are both spherical.

[0075] The radian of the spherical surface matches the outer wall surface of the material cavity 3. When the material cavity 3 abuts against the first positioning hole, the outer wall surface of the material cavity 3 can be completely attached to the inner wall surface of the first positioning hole.

[0076] Further, the push rod 2 is threadedly connected to the piston rod of the cylinder 1. Thereby, it is convenient to adjust the axial position of the push rod 2, so that an appropriate distance is maintained between the push rod 2 and the outer nozzle 6, improving the mixing and injection effects of flavors and fragrances.

[0077] The anti-drip injection type dual-medium spraying mechanism provided by the embodiment of the present application realizes the injection or blocking of flavors and fragrances by means of the sliding fit between the push rod and the material-gas mixing pipe, and realizes the avoidance of dripping of the material liquid from the material-gas mixing pipe after the production is completed.
