[0045] Inhalation administration is the most simple and effective administration route for treating respiratory diseases such as asthma, and is currently achieved by using a nebulizer. In use, the nebulizer needs to suck the liquid medicine in the medicine bottle into the pump body through the suction pipe by the action of the compression spring, and finally the liquid medicine is sprayed out by the nozzle. In this process, the liquid medicine is mainly atomized into fine particles by the nozzle. However, in the actual treatment process, researchers have found that due to the unreasonable structure design of the nozzle, the atomized particles sprayed by the nozzle are not uniform, that is, the spray sprayed by the existing nozzle has the problem of poor atomization effect, which reduces the absorption rate of the human lung.

[0046] The present application provides a nozzle and a nebulizer, which aims to solve the technical problem of poor atomization effect of the nozzle of the existing nebulizer.

[0047] Please refer to FIG. 1 and FIG. 2, in an embodiment of the present application, the nozzle comprises a body 100, a first shunt unit 200 and a second shunt unit 300, the body 100 comprises a first plate body 110 and a second plate body 120, the first plate body 110 and the second plate body 120 surround 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 shunt unit 200 is arranged in the first dispersion area 132, and the first shunt unit 200 has a shunt part 210 and a reflux part 220, the reflux part 220 can make part of the liquid flow reversely, the liquid changed flow direction by the reflux part 220 can collide with the liquid shunted by the shunt part 210, and the second shunt unit 300 is arranged in the second dispersion area 133.

[0048] The technical scheme of the present application can improve the flow rate of the liquid medicine by forming a local reverse flow through the setting of the flow dividing part 210 and the backflow part 220, so that the atomized particles of the liquid medicine sprayed through the nozzle are more uniform, and the atomization effect is improved. In the present embodiment, the first plate body 110 and the second plate body 120 form a liquid passing channel, in use, the liquid medicine will flow from the liquid inlet 131, and then pass through the first dispersion area 132, the second dispersion area 133 and the flow collecting area 134, and finally be sprayed from the liquid outlet 135. The first flow dividing 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 flow dividing 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 flow dividing part 210 can divide the flow of the liquid medicine to increase the flow channel of the liquid medicine in a limited space, and improve the flow rate, and the backflow part 220 can make the liquid medicine flow in the opposite direction. Specifically, when the liquid medicine flows through the first dispersion area 132, it will be divided under the action of the flow dividing part 210, and at the same time, it will change the flow direction under the action of the backflow part 220 and start to flow in the opposite direction, and the liquid medicine flowing in the opposite direction will collide with the liquid medicine divided by the flow dividing part 210; then the liquid medicine flowing in the opposite direction will be forced to change the flow direction under the action of the positive flow pressure and start to flow in the positive direction, that is, in this process, the backflow part 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 improving the flow rate of the liquid medicine. The nozzle can improve the flow rate of the liquid medicine by setting the flow dividing part 210 and the backflow part 220 in the first dispersion area 132 to form a local reverse flow, so that the atomized particles of the liquid medicine sprayed through the nozzle are more uniform, and the atomization effect is improved. The nozzle is applied to the field of atomizer technology.

[0049] It should be noted that by designing the flow distribution part 210 to guide the fluid into the micro flow channel at a specific angle, the flow distribution is optimized, the direct impact of the fluid on the flow channel wall is reduced, the energy loss caused by friction and impact is reduced, and the fluid can accelerate more smoothly and maintain a high flow rate. The backflow part 220 skillfully uses the principle of fluid dynamics to guide the fluid to flow in the opposite direction after reaching a certain position, and when it meets the forward flowing fluid, it produces local momentum exchange. The interaction between the reverse flow and the forward flow produces turbulence, increasing the mixing and momentum transfer of the fluid, effectively increasing the kinetic energy and overall flow rate of the fluid. In addition, the design of the backflow part 220 also promotes the secondary dispersion of the fluid, which helps to form smaller fluid particles with larger surface area and better dispersion, thereby achieving more uniform distribution of the particles when sprayed, optimizing the spray effect. In addition, the above-mentioned more uniform flow direction and flow rate refers to the more consistent spatial distribution of the flow path and direction of the fluid during the flow process. The above-mentioned more stable flow of the liquid medicine refers to the more orderly flow of each part of the liquid medicine. The above-mentioned forward fluid pressure 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 it from the liquid inlet 131 into the spray head, and then flow through the first dispersion area 132, the second dispersion area 133 and the flow convergence area 134, and finally be sprayed from the liquid outlet 135.

[0050] Please refer to FIG. 2 and FIG. 3, in an embodiment of the present application, the first flow distribution unit 200 includes a first flow distribution assembly 230 and a plurality of second flow distribution assemblies 240 which are arranged in sequence and spaced apart along a first direction of the body 100, the first flow distribution assembly 230 includes a plurality of first flow distribution blocks 231 which are arranged in sequence and spaced apart along a second direction of the body 100, and the second flow distribution assembly 240 includes a plurality of second flow distribution blocks 241 which are arranged in sequence and spaced apart along the second direction of the body 100; the first flow distribution block 231 of the first flow distribution assembly 230 is arranged alternately with the second flow distribution block 241 of the adjacent second flow distribution assembly 240, and the second flow distribution blocks 241 of any two adjacent second flow distribution assemblies 240 are arranged alternately. Wherein, 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 an embodiment, the first direction can be the direction indicated by the liquid inlet 131 to the liquid outlet 135, and the second direction can be the vertical direction of the first direction. By arranging the first flow distribution block 231 and the second flow distribution block 241 in the first dispersion area 132 and arranging the first flow distribution block 231 and the second flow distribution block 241 in a rectangular staggered manner, the flow channel can be increased in a limited space to disperse the flow of the liquid medicine, increase the flow rate of the liquid medicine in each flow channel, and thus increase the flow rate of the liquid medicine in the entire first dispersion area 132.

[0051] Referring to FIG. 3, in an embodiment of the present application, each first flow distribution block 231 is formed with a flow distribution arc 2311 on the side facing the liquid inlet 131; and each second flow distribution block 241 is formed with a flow distribution corner 2411 and a backflow arc 2412 on the side facing the liquid inlet 131. Specifically, the flow distribution arc 2311 can disperse the liquid medicine when the liquid medicine flows into the first dispersion area 132. The flow distribution corner 2411 can cause the liquid medicine to flow in different directions when the liquid medicine flows through, so as to increase the flow path of the liquid medicine in a limited space and improve the flow rate; and the backflow arc 2412 can cause the liquid medicine to flow in a reverse direction, so as to guide the liquid medicine to form a local reverse flow in the first dispersion area 132, increase the kinetic energy of the liquid medicine, and thus improve the flow rate of the liquid medicine. In an embodiment, the first flow distribution block 231 and the second flow distribution block 241 are the same in structure, and the first flow distribution block 231 and the second flow distribution block 241 are oppositely arranged in the first dispersion area 132; and the size of the first flow distribution block 231 gradually decreases along the first direction.

[0052] In an embodiment of the present application, the first flow distribution assembly 230 further comprises a first dispersion column 232, and the first dispersion column 232 is arranged between any two adjacent first flow distribution blocks 231; and the second flow distribution assembly 240 further comprises a second dispersion column 242, and the second dispersion column 242 is arranged between any two adjacent second flow distribution blocks 241. Specifically, the first dispersion column 232 arranged between any two first flow distribution blocks 231 and the second dispersion column 242 arranged between any two second flow distribution blocks 241 can cause the liquid medicine to flow in different directions when the liquid medicine flows through, so as to increase the flow path of the liquid medicine in a limited space and improve the flow rate. In the embodiment, the backflow part 220 comprises the backflow arc 2412, and the flow distribution part comprises the flow distribution arc 2311, the flow distribution corner 2411, the first dispersion column 232 and the second dispersion column 242.

[0053] Referring to FIGS. 2 and 3, the first dispersion area 132 is provided with a liquid inlet area 136 on the side close to the liquid inlet 131, the liquid inlet area 136 is spaced apart from the first dispersion area 132 along the second direction of the body 100 and is provided with a plurality of dispersion blocks 1361, and each dispersion block 1361 is formed with a flow distribution curved surface 1362 on the side facing the first dispersion area 132. In the embodiment, the first dispersion area 132 is provided with the liquid inlet area 136 on the side close to the liquid inlet 131, and in use, the liquid medicine flows into the liquid inlet 131, and then flows through the liquid inlet area 136, the first dispersion area 132, the second dispersion area 133 and the flow collection area 134 in sequence, and finally is sprayed out of the liquid outlet 135. The flow distribution 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 more smoothly into the first dispersion area 132. In an embodiment, the flow distribution curved surface 1362 can be a flow distribution round corner.

[0054] In the 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 flow splitting curved surface 1362. When the liquid medicine flows through the first dispersion area 132, the flow splitting arc 2311 and the flow splitting column 310 will disperse the liquid medicine to increase the flow channel in a limited space and improve the flow rate of the liquid medicine; then under the action of the flow splitting angle 2411, the liquid medicine will flow along the two sides of the flow splitting angle 2411, and then part of the liquid medicine will start to flow in reverse under the action of the backflow arc 2412, collide with the liquid medicine split by the flow splitting arc 2311, and finally under the action of the positive fluid pressure, the liquid medicine flowing in reverse will be forced to change the flow direction and start to flow forward. In this process, the backflow 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 improving the flow rate of the liquid medicine. By arranging the second flow splitting block 241 in multiple layers and staggered in the first dispersion area 132, the liquid medicine can repeatedly flow in, split, backflow and drainage, thereby making the flow direction and flow rate of the liquid medicine more uniform. At the same time, by arranging the backflow arc 2412, a local reverse flow is formed in the first dispersion area 132, which can improve the flow rate of the liquid medicine to make the atomized particles of the sprayed liquid medicine more uniform and improve the atomization effect.

In the second dispersion area 133, by arranging the flow splitting column 310 and the backflow assembly 320, the flow channel can be subdivided, thereby making the flow of the liquid medicine more balanced.

Among them, the third dispersion column 330 can cause the drug liquid to shunt when the drug liquid flows through, so as to increase the flow channel of the drug liquid in a limited space and improve the flow rate. In the present embodiment, the plurality of blocks 311 of the shunt column 310 are arranged at intervals along the first direction, the plurality of reflux blocks 321 of the reflux assembly 320 are arranged at intervals along the first direction, and the plurality of third dispersion columns 330 are distributed in the second dispersion area 133, which can make the arrangement of the second shunt unit 300 more regular, and then make the flow of each part of the drug liquid more orderly and make the flow of the drug liquid more stable; at the same time, it can also subdivide the flow channel of the drug liquid to improve the flow rate of the drug liquid.

Part of the drug liquid will change the flow direction under the action of the reflux block 321 and pass through the micro-flow gap 312 between the adjacent two blocks 311, and then the drug liquid passing through the micro-flow gap 312 will collide with the drug liquid flowing forward and the drug liquid whose flow direction is changed by the reflux assembly 320; it can subdivide the flow channel to make the flow of the drug liquid more balanced.
