Inhalation is the simplest and most effective way to treat respiratory diseases such as asthma. Currently, inhalation is mainly achieved through a nebulizer. When in use, the nebulizer needs to use the action of the compression spring to suck the liquid medicine in the medicine bottle into the pump body through the straw, and finally spray the liquid medicine from the nozzle. In this process, the liquid medicine is mainly atomized into fine particles through the nozzle. However, in the actual treatment process, researchers found that due to the unreasonable structural design of the nozzle, the atomized particles of the spray sprayed by the nozzle are uneven, that is, the spray sprayed by the existing nozzle has a poor atomization effect, which will reduce the absorption rate of the human lungs.

The present invention provides a nozzle and an atomizer, aiming to solve the technical problem of poor atomization effect of the nozzle of the existing atomizer.

Please refer to Figures 1 and 2. In one embodiment of the present invention, the nozzle includes a body 100, a first diverter unit 200 and a second diverter unit 300. The body 100 includes a first plate body 110 and a second plate body 120. The first plate body 110 and the second plate body 120 are surrounded to form a liquid passage. The liquid passage has a liquid inlet 131, a liquid outlet 135, a first dispersion area 132, a second dispersion area 133 and a confluence area 134 arranged in sequence from the liquid inlet 131 to the liquid outlet 135. The first diverter unit 200 is arranged in the first dispersion area 132, and the first diverter unit 200 has a diverter portion 210 and a reflux portion 220. The reflux portion 220 can make part of the liquid flow in the reverse direction. The liquid after the flow direction is changed by the reflux portion 220 can collide with the liquid after being diverted by the diverter portion 210. The second diverter unit 300 is arranged in the second dispersion area 133.

The technical solution of the present invention can increase the flow rate of the liquid medicine by setting the diverter 210 and the reflux 220 to form a local counterflow, so that the atomized particles of the liquid medicine sprayed by the nozzle are more uniform, and the atomization effect is improved. In this embodiment, the first plate body 110 and the second plate body 120 are surrounded to form a liquid passage. When in use, the liquid medicine will flow in from the liquid inlet 131, and pass through the first dispersion area 132, the second dispersion area 133 and the confluence area 134 in sequence, and finally spray out from the liquid outlet 135. The first diverter unit 200 arranged in the first dispersion area 132 can make the flow direction and flow rate of the liquid medicine more uniform; the second diverter unit 300 arranged in the second dispersion area 133 can make the flow of the liquid medicine more stable. In the first dispersion area 132, the diverter 210 can divert the liquid medicine when it flows through, so as to increase the flow channel of the liquid medicine in a limited space and increase the flow rate, and the reflux 220 can make the liquid medicine flow in the reverse direction. Specifically, when the liquid medicine flows through the first dispersion area 132, it will be diverted under the action of the diverter 210, and will also change the flow direction under the action of the reflux 220 and start to flow in the reverse direction, and the liquid medicine flowing in the reverse direction will collide with the liquid medicine diverted by the diverter 210; then, the liquid medicine flowing in the reverse direction will be forced to change the flow direction under the action of the positive fluid pressure and start to flow in the forward direction, that is, in this process, the reflux 220 can guide the liquid medicine to form a local reverse flow in the first dispersion area 132 to increase the kinetic energy of the liquid medicine, thereby increasing the flow rate of the liquid medicine. The nozzle is provided with the diverter 210 and the reflux 220 in the first dispersion area 132 to form a local reverse flow, which can increase the flow rate of the liquid medicine, so that the atomized particles of the liquid medicine sprayed through the nozzle are more uniform, thereby improving the atomization effect. The nozzle is applied to the field of atomizer technology.

It should be noted that by designing the flow divider 210 to guide the fluid into the microchannel at a specific angle, the streamline distribution is optimized, the direct impact between the fluid and the channel wall is reduced, thereby reducing the energy loss caused by friction and impact, so that the fluid can be accelerated more smoothly and maintain a high flow rate. The reflux portion 220 cleverly uses the principle of fluid dynamics to guide the reverse flow of the fluid after it reaches a certain position, and produces a local momentum exchange when it meets the forward flowing fluid. This interaction between the reverse flow and the forward flow will produce turbulence, increase the mixing and momentum transfer of the fluid, and effectively improve the kinetic energy and overall flow rate of the fluid. In addition, the design of the reflux portion 220 also promotes the secondary dispersion of the fluid, which helps to form finer fluid particles. These particles have a larger surface area and better dispersibility, so that they can have a more uniform morphological distribution when ejected, optimizing the spray effect. In addition, the more uniform flow direction and flow rate mentioned in the above content means that during the fluid flow process, the flow path and direction of the fluid are more uniformly distributed in space. The more stable flow of the liquid medicine mentioned in the above content means that the flow of each part of the liquid medicine is more orderly. The positive fluid pressure mentioned in the above content is provided by the pump body 540. Specifically, when the atomizer is in use, the pump body 540 will continuously pump the liquid medicine to pump the liquid medicine from the liquid inlet 131 into the nozzle, and then pass through the first dispersion area 132, the second dispersion area 133 and the confluence area 134 in sequence, and finally spray out from the liquid outlet 135.

Please refer to FIG. 2 and FIG. 3. In one embodiment of the present invention, the first flow diversion unit 200 includes a first flow diversion component 230 and a plurality of second flow diversion components 240 which are sequentially arranged in a first direction of the body 100 at intervals. The first flow diversion component 230 includes a plurality of first flow diversion blocks 231 which are arranged in a second direction of the body 100 at intervals. The second flow diversion component 240 includes a plurality of second flow diversion blocks 241 which are arranged in a second direction of the body 100 at intervals. The first flow diversion blocks 231 of the first flow diversion component 230 are staggered with the second flow diversion blocks 241 of the adjacent second flow diversion components 240. The second flow diversion blocks 241 of any two adjacent second flow diversion components 240 are staggered. The first direction refers to the direction indicated by X in FIG. 2, and the second direction refers to the direction indicated by Y in FIG. 2. In a specific embodiment, the first direction may be the direction indicated by the liquid inlet 131 to the liquid outlet 135, and the second direction may be the perpendicular direction to the first direction. By setting the first diverter block 231 and the second diverter block 241 in the first dispersion area 132, and arranging the first diverter block 231 and the second diverter block 241 in a rectangular staggered manner, it is possible to increase the flow channel in a limited space to disperse the flow of the drug solution, increase the flow rate of the drug solution in each flow channel, and thereby increase the flow rate of the drug solution in the entire first dispersion area 132.

Please refer to FIG. 3 . In one embodiment of the present invention, each first diverter block 231 is formed with a diverter arc 2311 on the side facing the liquid inlet 131; each second diverter block 241 is formed with a diverter angle 2411 and a reflux arc 2412 located on both sides of the diverter angle 2411 on the side facing the liquid inlet 131. Specifically, the diverter arc 2311 can disperse the liquid medicine when it flows into the first dispersion area 132. The diverter angle 2411 can divert the liquid medicine when it flows through, so as to increase the flow channel of the liquid medicine in a limited space and increase the flow rate; the reflux arc 2412 can make the liquid medicine flow in the reverse direction, so as to guide the liquid medicine to form a local counterflow in the first dispersion area 132, increase the kinetic energy of the liquid medicine, and thus increase the flow rate of the liquid medicine. In a specific embodiment, the first diverter block 231 and the second diverter block 241 have the same structure and are disposed in the first dispersion area 132 in an opposite manner; and the size of the first diverter block 231 gradually decreases along the first direction.

In one embodiment of the present invention, the first diversion component 230 also includes a first dispersion column 232, and the first dispersion column 232 is disposed between any two adjacent first diversion blocks 231; the second diversion component 240 also includes a second dispersion column 242, and the second dispersion column 242 is disposed between any two adjacent second diversion blocks 241. Specifically, the first dispersion column 232 disposed between any two first diversion blocks 231 and the second dispersion column 242 disposed between any two second diversion blocks 241 can divert the medicinal liquid when the medicinal liquid flows through, so as to increase the flow channel of the medicinal liquid in a limited space and improve the flow rate. In this embodiment, the reflux portion 220 includes a reflux arc 2412, and the diversion portion includes a diversion arc 2311, a diversion angle 2411, a first dispersion column 232, and a second dispersion column 242.

Please refer to FIG. 2 and FIG. 3 , a liquid inlet area 136 is provided on one side of the first dispersion area 132 close to the liquid inlet 131, and a plurality of dispersion blocks 1361 are arranged at intervals in the second direction of the body 100 in the liquid inlet area 136, and a flow dividing curved surface 1362 is formed on the side of each dispersion block 1361 facing the first dispersion area 132. In this embodiment, a liquid inlet area 136 is provided on one side of the first dispersion area 132 close to the liquid inlet 131, and when in use, the liquid medicine flows in from the liquid inlet 131, and passes through the liquid inlet area 136, the first dispersion area 132, the second dispersion area 133 and the confluence area 134 in sequence, and finally sprays out from the liquid outlet 135. Among them, the flow dividing curved surface 1362 formed on the side of the dispersion block 1361 facing the first dispersion area 132 can guide the flow of the liquid medicine, so that the liquid medicine flows into the first dispersion area 132 more smoothly. In a specific embodiment, the flow dividing curved surface 1362 can be a flow dividing fillet.

In this embodiment, after the liquid medicine flows in from the liquid inlet 131, it will enter the first dispersion area 132 more smoothly under the action of the diversion curved surface 1362. When the liquid medicine flows through the first dispersion area 132, the diversion arc 2311 and the diversion column 310 will disperse the liquid medicine to increase the flow channel in a limited space and increase the flow rate of the liquid medicine; then under the action of the diversion angle 2411, the liquid medicine will move along both sides of the diversion angle 2411, and then part of the liquid medicine will start to flow in the reverse direction under the action of the reflux arc 2412, and collide with the liquid medicine diverted by the diversion arc 2311, and finally under the action of the positive fluid pressure, the liquid medicine flowing in the reverse direction will be forced to change the flow direction and start to flow in the forward direction. In this process, the reflux arc 2412 can guide the liquid medicine to form a local reverse flow in the first dispersion area 132 to increase the kinetic energy of the liquid medicine, thereby increasing the flow rate of the liquid medicine. By setting up the multi-layer staggered second diversion blocks 241 in the first dispersion area 132, the medicine can be repeatedly flowed in, diverted, refluxed and drained, so that the flow direction and flow rate of the medicine are more uniform. At the same time, by setting the reflux arc 2412, a local countercurrent is formed in the first dispersion area 132, which can increase the flow rate of the medicine, so that the atomized particles of the sprayed medicine are more uniform, thereby improving the atomization effect.

Please refer to FIG. 2 and FIG. 4 . In one embodiment of the present invention, the second flow dividing unit 300 includes a plurality of flow dividing columns 310 and a plurality of flow return components 320. The plurality of flow dividing columns 310 and the plurality of flow return components 320 are alternately arranged along the second direction of the body 100, and the flow dividing columns 310 are formed with microflow gaps 312. The liquid after the flow direction is changed by the flow return components 320 can pass through the microflow gaps 312. In this embodiment, when the liquid medicine flows through the second dispersion area 133, the flow return components 320 can change the flow direction of the liquid medicine, and make the liquid medicine flow through the microflow gaps 312 of the flow dividing columns 310 to the other side of the flow dividing columns 310. The liquid medicine passing through the microflow gaps 312 will collide with the liquid medicine flowing in the forward direction and the liquid medicine after the flow direction is changed by the flow return components 320 at the same time. In the second dispersion area 133, by setting the flow dividing columns 310 and the flow return components 320, the flow channel can be subdivided, thereby making the flow of the liquid medicine more balanced.

In one embodiment of the present invention, the flow splitter column 310 includes a plurality of blocks 311 spaced apart along the first direction of the body 100, and a microflow gap 312 is formed between any two adjacent blocks 311; the reflux component 320 includes a plurality of reflux blocks 321 spaced apart along the first direction of the body 100, and two reflux curved surfaces 3212 are formed on the side of each reflux block 321 facing the first dispersion area 132, and the two reflux curved surfaces 3212 are spaced apart along the second direction of the body 100. The second flow splitter unit 300 also includes a plurality of third dispersion columns 330, and the plurality of third dispersion columns 330 are evenly distributed in the second dispersion area 133. The third dispersion columns 330 can divert the liquid medicine when it flows through, so as to increase the flow path of the liquid medicine in a limited space and improve the flow rate. In this embodiment, the multiple blocks 311 of the shunt column 310 are spaced apart along the first direction, the multiple reflux blocks 321 of the reflux component 320 are spaced apart along the first direction, and the multiple third dispersion columns 330 are evenly distributed in the second dispersion area 133, which can make the arrangement of the second shunt unit 300 more regular, thereby making the flow of each part of the liquid medicine more orderly and the flow of the liquid medicine more stable; at the same time, it can also subdivide the flow channel of the liquid medicine to increase the flow rate of the liquid medicine. In a specific embodiment, the size of the microflow gap 312 is smaller than the distance between any two adjacent third dispersion columns 330. In a more specific embodiment, the size of the microflow gap 312 is 3μm, and the distance between any two adjacent third dispersion columns 330 is 10μm.

In this embodiment, when the liquid medicine flows through the second dispersion area 133, the third dispersion column 330 will divert the liquid medicine to increase the flow channel in a limited space and increase the flow rate of the liquid medicine. Part of the liquid medicine will change its flow direction under the action of the reflux block 321 and pass through the microflow gap 312 between two adjacent blocks 311. The liquid medicine that then passes through the microflow gap 312 will collide with the liquid medicine flowing in the forward direction and the liquid medicine whose flow direction is changed by the reflux component 320 at the same time; it can subdivide the flow channel and make the flow of the liquid medicine more balanced.

Please refer to FIG. 2 and FIG. 5 . In one embodiment of the present invention, the nozzle further includes a plurality of fourth dispersion columns 400, and the plurality of fourth dispersion columns 400 are evenly distributed in the confluence area 134. In this embodiment, by evenly distributing the plurality of fourth dispersion columns 400 in the confluence area 134, the flow of each part of the liquid medicine can be made more orderly, that is, the flow of the liquid medicine can be made more stable. In a specific embodiment, the distance between any two adjacent fourth dispersion columns 400 is equal to the distance between any two adjacent third dispersion columns 330.

In this embodiment, the liquid discharge directions of the two liquid spraying ports 1111 are designed to be perpendicular to each other, which can make the liquid sprayed from the two liquid spraying ports 1111 collide with each other to form tiny and uniform atomized particles, thereby ensuring the atomization effect. In a specific embodiment, the angle between each converging wall 111 and the central axis of the nozzle is α, wherein 75°≤α≤80°; the angle between the converging wall 111 and the central axis of the nozzle is limited to between 75° and 80°, so as to better converge the liquid medicine to ensure the spraying effect of the liquid medicine.

In one embodiment of the present invention, the first diverter unit 200 has a first diverter gap, the second diverter unit 300 has a second diverter gap, and the size of the first diverter gap is greater than the size of the second diverter gap. In this embodiment, the size of the first diverter gap is greater than the size of the second diverter gap. When the liquid medicine flows through the first dispersion area 132 and the second dispersion area 133 in sequence, the flow rate can be gradually increased, so that the liquid medicine has a higher flow rate when it is sprayed from the liquid spray port 1111, thereby making the atomized particles of the liquid medicine sprayed from the nozzle more uniform and improving the atomization effect. In this embodiment, the first diverter unit 200, the second diverter unit 300 and the fourth dispersion column 400 arranged in the confluence area 134 are all formed on the first plate 110 by photolithography or etching.
