Description

Technical Field

[0001] This utility model relates to the field of ultrasonic atomization spraying technology, and in particular to an ultrasonic-assisted liquid spraying atomization enhancement device. Background Technology

[0002] In modern industrial production and scientific research experiments, ultrasonic-assisted liquid spraying atomization enhancement devices have been widely used in many fields such as electronics manufacturing, biomedicine, and material surface treatment due to their unique advantages. By combining ultrasonic technology with liquid spraying atomization, the atomization effect and spraying quality are effectively improved. However, in actual use, especially in the atomizing nozzles of the device, cleaning problems have gradually become prominent.

[0003] Traditional ultrasonic-assisted liquid spraying atomization enhancement devices are equipped with atomizing nozzles whose structural design, while meeting the requirements for high-efficiency atomization, also creates many obstacles for subsequent cleaning work. The nozzles contain tortuous guide channels, tiny flow-diverting orifices, and a fine array of atomizing micropores. While these structures can achieve fine atomization of the liquid, reducing droplet sizes to the micrometer or even nanometer level—meeting the requirements for uniform and precise photoresist spraying in electronic chip manufacturing—they also cause liquid to easily remain and dry after flowing through these areas.

[0004] In the biopharmaceutical field, after use, residual drug components, especially those containing biomolecules such as proteins and polysaccharides, accumulate in the nozzle channels and micropores of spray nozzles used for drug spraying, forming stubborn stains. If not cleaned promptly after each use, long-term operation can lead to difficult-to-clean nozzles and clogged nozzles, thus affecting the effectiveness of atomized spraying. In view of the above reasons, this application proposes an ultrasonic-assisted liquid spraying atomization enhancement device with an automatic nozzle rinsing function. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an ultrasonic-assisted liquid spraying atomization enhancement device.

[0006] The technical solution of this utility model is: an ultrasonic-assisted liquid spraying atomization enhancement device, including an atomizing nozzle assembly for liquid spraying and a protective cover covering the top of the atomizing nozzle assembly. The output end of the atomizing nozzle assembly is also connected to a liquid delivery module for liquid transportation.

[0007] A cleaning component located inside a protective cover is also provided on one side of the atomizing nozzle assembly. The cleaning component includes a cylinder installed on the inner wall of the top of the protective cover and a rinsing nozzle that is raised and lowered by the cylinder. The input end of the rinsing nozzle is connected to a mixing box, and a liquid storage bladder is connected to one side of the mixing box.

[0008] Optionally, the infusion module includes a first connecting tube and a second connecting tube, wherein the diameter of the first connecting tube is larger than the diameter of the second connecting tube, and a reinforcing plate for increasing the pressure of the sprayed liquid is provided inside the first connecting tube.

[0009] Optionally, the outer ring of the connecting pipe is provided with an external thread for connecting with the sprayed liquid, and the reinforcing plate is spiral in shape with a spacing of 5-8mm.

[0010] Optionally, the output end of the cylinder is also connected to a mounting plate, which has an "L" shaped structure. The vertical side plate of the mounting plate has a mounting groove, and the mixing box is installed in the mounting groove.

[0011] Optionally, the top of the mixing chamber is connected to an infusion hose for conveying the flushing liquid to the atomizing nozzle assembly, and multiple sets of flushing nozzles are arranged along the bottom of the mixing chamber.

[0012] Optionally, the output end of the cylinder is also connected to a fixing rod, and a pressure plate perpendicularly arranged therefrom is fixedly connected to the top of the fixing rod.

[0013] Optionally, the inner wall of one side of the protective cover is provided with a cavity for installing the liquid storage bladder, and one end of the pressure plate is located in the cavity and positioned above the liquid storage bladder.

[0014] Optionally, an arc-shaped connecting pipe for connecting and communicating with the liquid storage bladder and the mixing box is provided.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects:

[0016] This utility model, through the lifting design of the cleaning component, combined with the layout of the mixing box and multiple sets of rinsing nozzles, can achieve all-round coverage cleaning of the atomizing nozzle component and the atomizing nozzle. It solves the problem that traditional cleaning tools cannot reach into narrow spaces, ensures the stability of atomization and spraying performance, reduces parameter deviation, and significantly improves the unobstructedness of the nozzle micropores and the smoothness of the flow channel after cleaning, avoiding the deviation of atomized particle size caused by residual blockage.

[0017] This utility model also uses a design where the diameter of the first connecting pipe is larger than the diameter of the second connecting pipe, so that the liquid forms a high-speed rotating flow before entering the atomization zone, thereby increasing the contact area with the ultrasonic waves. The reinforcing plate inside the cavity of the first connecting pipe forces the liquid to form turbulence, promotes the uniform distribution of ultrasonic energy, and enhances the ultrasonic atomization spraying effect.

[0018] In summary, this invention achieves all-round cleaning of the nozzle, ensures atomization performance, reduces particle size deviation, and adopts a structure in which the diameter of the first connecting pipe is larger than the diameter of the second connecting pipe. Combined with the internal reinforcing plate, it forms turbulence, enhances the contact area between the liquid and the ultrasonic waves and the uniformity of energy distribution, and significantly improves the atomization spraying effect.

[0034] Example

[0035] like Figure 1-5 As shown, the present invention proposes an ultrasonic-assisted liquid spraying atomization enhancement device, including an atomizing nozzle assembly 3 for liquid spraying and a protective cover 1 covering the top of the atomizing nozzle assembly 3. The output end of the atomizing nozzle assembly 3 is also connected to a liquid delivery module 2 for liquid delivery. The liquid delivery module 2 includes a first connecting pipe 21 and a second connecting pipe 22. The outer ring of the first connecting pipe 21 is provided with an external thread for connecting to the spraying liquid. The diameter of the first connecting pipe 21 is larger than the diameter of the second connecting pipe 22. A reinforcing plate 23 for increasing the pressure of the spraying liquid is provided inside the first connecting pipe 21. The reinforcing plate 23 is spiral in shape and the spacing is 5mm.

[0036] like Figure 2-4 As shown, a cleaning component 4 located inside the protective cover 1 is also raised and lowered on one side of the atomizing nozzle assembly 3. The cleaning component 4 includes a cylinder 41 installed on the inner wall of the top of the protective cover 1 and a rinsing nozzle 45 raised and lowered by the cylinder 41. The input end of the rinsing nozzle 45 is connected to a mixing box 43, and the output end of the cylinder 41 is also connected to a fixing rod 48. A pressure plate 49 is fixedly connected to the top of the fixing rod 48 and is perpendicular to it.

[0037] like Figure 2As shown, the output end of the cylinder 41 is also connected to a mounting plate 42. The mounting plate 42 has an "L" shaped structure. The vertical side plate of the mounting plate 42 has a mounting groove. The mixing box 43 is installed in the mounting groove. The top of the mixing box 43 is connected to a liquid delivery hose 44 for rinsing the atomizing nozzle assembly 3. Multiple sets of rinsing nozzles 45 are arranged along the bottom of the mixing box 43. The rinsing nozzles 45 are inclined. When moved to a designated position, the nozzle end of the rinsing nozzle 45 corresponds to the position of the atomizing nozzle hole of the atomizing nozzle assembly 3 for rinsing. A liquid storage bladder 47 is connected to one side of the mixing box 43. A cavity 11 for installing the liquid storage bladder 47 is opened on the inner wall of one side of the protective cover 1. One end of the pressure plate 49 is located in the cavity 11 and is set above the liquid storage bladder 47. An arc-shaped connecting pipe 46 for connecting the liquid storage bladder 47 and the mixing box 43 is provided.

[0038] When liquid spraying is performed, the liquid to be sprayed is connected to the conveying system through the external thread of the outer ring of the connecting pipe 21 and enters the cavity of the connecting pipe 21. Since the diameter of the connecting pipe 21 is larger than that of the connecting pipe 22, a pressure difference is formed when the liquid flows through the variable diameter channel. At the same time, the spiral reinforcing plate 23 inside the connecting pipe 21 forces the liquid to flow along the spiral path, forming high-speed turbulence. This turbulent state increases the contact area between the liquid and the ultrasonic vibration surface of the atomizing nozzle assembly 3, so that the ultrasonic energy is transmitted to the liquid more evenly, accelerating the liquid to break into tiny droplets, which are finally sprayed out through the atomizing nozzle of the atomizing nozzle assembly 3, achieving efficient and uniform atomized spraying.

[0039] When it is necessary to clean the atomizing nozzles of the atomizing nozzle assembly 3, activate the cleaning function of the cleaning assembly 4:

[0040] The cylinder 41 drives the flushing nozzle 45, mounting plate 42, fixing rod 48, and pressure plate 49 to descend as a whole. The mounting plate 42 provides stable support for the mixing box 43 through the mounting groove, ensuring the accurate positioning of the mixing box 43. At the same time, the fixing rod 48 drives the pressure plate 49 to slide along the cavity 11, squeezing the liquid storage bladder 47. This causes the cleaning liquid, such as detergent, pre-filled in the liquid storage bladder 47 to be squeezed into the mixing box 43. The cleaning water flows into the mixing box 43 through the infusion hose 44, mixes with the detergent, and is finally sprayed out by the multiple flushing nozzles 45 at the bottom of the mixing box 43. Because the flushing nozzles 45 are tilted and precisely aligned with the nozzle holes, the cleaning liquid can directly flush the inner wall and surrounding residues of the nozzle holes, such as cured coatings and particulate impurities, solving the problem that traditional tools cannot penetrate micropores. After cleaning, the cylinder 41 drives the flushing nozzles 45 to rise and reset. The protective cover 1 prevents the cleaning liquid from splashing and contaminating other components, ensuring stable atomization performance of the device in the next use.

[0041] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
