[0035] Atomizers are treatment instruments that are currently used more frequently, especially for various respiratory diseases. Due to the increasingly serious air pollution, traditional medication can no longer effectively treat diseases, so the status of atomizers has been continuously improved. The size of atomized particles and the atomization range are directly related to the atomization effect. Currently, the injection holes of atomizers are mostly arranged singly, which will cause the height and injection distance of the injection liquid ejected by the upper and lower atomizers to be different, resulting in uneven ejection of the injection liquid.

[0036] In view of this, the present utility model provides an atomizer, Figures 1 to 2 which is a schematic diagram of an embodiment of the atomizer.

[0037] Please refer to Figure 1 , and a kind of atomizer 100 is proposed, which is used in the field of medical devices and includes a main body 1 arranged vertically and a nozzle 2 installed on the main body 1. The nozzle 2 is installed on the main body 1, and a plurality of injection holes 23 are arranged on the nozzle 2. Among two adjacent injection holes 23 in the vertical direction, the aperture of the upper injection hole 23 is larger than the aperture of the lower injection hole 23.

[0038] In the technical solution provided by the utility model, an atomizer 100 is proposed, which is used in the field of medical devices, and includes a main body 1 arranged vertically and a nozzle 2 installed on the main body 1. The nozzle 2 is installed on the main body 1, and a plurality of injection holes 23 are arranged on the nozzle 2. Among the two adjacent injection holes 23 in the vertical direction, the aperture of the injection hole 23 on the upper side is larger than the aperture of the injection hole 23 on the lower side. The aperture of the injection hole 23 is adjusted to adapt to the pressure of the atomizer 100 at different heights.

[0039] In this embodiment, the aperture of the injection hole 23 is D, and 0.1mm≤D≤0.4mm. When the aperture of the injection hole 23 is 0.1mm, the injection hole 23 is arranged above the nozzle 2, and the pressure above the nozzle 2 is smaller than the pressure below the nozzle 2. When the aperture of the injection hole 23 is 0.1mm, it can ensure that enough of the injection liquid is sprayed out. When the aperture of the injection hole 23 is 0.4mm, the injection liquid can be sprayed out and the sprayed injection liquid can have a certain distance from the injection hole 23. If the aperture of the injection hole 23 is too small, less than 0.1mm, the injection hole 23 may not spray the injection liquid. If the injection hole 23 is larger than 0.4mm, the sprayed injection liquid may flow out in large quantities.

[0040] The atomizer 100 also includes a liquid-gas converter 3 and a controller 4, wherein the liquid-gas converter 3 is arranged inside the main body 1, and the controller 4 is arranged inside the main body 1 and is electrically connected to the liquid-gas converter 3. The working principle of the liquid-gas converter 3 is based on the difference in physical properties between gas and liquid. In most cases, the gas has a lower density and a higher compressibility, while the liquid has a higher density and a lower compressibility. When the gas is compressed or cooled, it will be converted into the liquid, and when the liquid is heated or relaxed, it will be converted into the gas. The liquid-gas converter 3 is usually composed of a container and a series of control devices, and the container is used to contain the gas or the liquid and has appropriate pressure and temperature control devices. The control device can adjust the pressure and temperature in the container as needed to achieve the conversion of the gas to the liquid or the liquid to the gas. The controller 4 is used to directly control the liquid-gas conversion efficiency and control the efficiency or opening of other components.

[0041] Furthermore, the atomizer 100 further includes a display screen 5, which is fixedly disposed on the main body 1 and electrically connected to the controller 4. The display screen 5 displays various functions of various components of the atomizer 100, for example, a reflection that the atomizer 100 needs to add water, a reflection of the atomization effect of the atomizer 100, and other functional reflections.

[0042] In addition, in the left - right direction, the nozzle 2 is composed of a middle part 21 and two edge parts 22 on both sides of the middle part 21. In the up - down direction, the nozzle 2 includes an upper interval part, a middle interval part, and a lower interval part; a plurality of the injection holes 23 include a first injection hole 231 that is simultaneously in the upper interval part and the middle part 21, and a second injection hole 232 that is simultaneously in the upper interval part and the edge part 22. Among them, the aperture of the first injection hole 231 is larger than that of the second injection hole 232. In the left - right direction, the nozzle 2 is composed of a middle part 21 and two edge parts 22 on both sides of the middle part 21. From left to right, the injection surface of the nozzle 2 is divided into three regions. In the up - down direction, the nozzle 2 includes an upper interval part, a middle interval part, and a lower interval part. From top to bottom, the injection surface of the nozzle 2 is divided into three regions. Altogether, the injection surface is divided into nine regions. Among them, a plurality of the injection holes 23 include a first injection hole 231 that is simultaneously in the upper interval part and the middle part 21, and a second injection hole 232 that is simultaneously in the upper interval part and the edge part 22. Among them, the aperture of the first injection hole 231 is larger than that of the second injection hole 232. In this way, the aperture of the first injection hole 231 provided at the upper interval part and the middle part 21 is larger than the aperture of the second injection hole 232 at the upper interval part and the edge part 22. The aperture at the edge is set smaller, which is better for more of the injection liquid to be ejected from the middle. The first injection hole 231 can be above the second injection hole 232 in height.

[0043] Furthermore, the selection of the regions also affects the range of the ejected injection liquid. The middle part 21 and the two edge parts 22 are both collinearly arranged to form two side lines. The two side lines are symmetrically arranged about the up - down axis of the center of gravity of the nozzle 2, and the area of the middle part 21 is equivalent to the area of any one of the edge parts 22; and / or, the upper interval part, the middle interval part, and the lower interval part are all collinearly arranged to form two side lines. The two side lines are symmetrically arranged about the left - right axis of the center of gravity of the nozzle 2, and the area of the middle interval part accounts for 1 / 3 to 1 / 2 of the area of the nozzle 2. In this way, the range of the injection surface can be better evenly divided, and the layout of the corresponding injection holes 23 is more uniform and more in line with the selection of each region.

[0044] Furthermore, the aperture of the first injection hole 231 satisfies 0.35 ≤ D1 ≤ 0.4 mm, and / or the aperture of the second injection hole 232 satisfies 0.25 ≤ D2 ≤ 0.3 mm. It is preferred within this range, which can ensure that the injection liquid can be ejected in the area of the current nozzle 2, and setting a difference between the first injection hole 231 and the second injection hole 232 can make the injection more uniform.

[0045] Furthermore, in this embodiment, a plurality of the second injection holes 232 are provided in the middle interval portion, and the second injection holes 232 are equally distributed on the left and right edge portions 22 respectively; and / or a plurality of the second injection holes 232 are provided in the middle interval portion of the nozzle 2, and the second injection holes 232 are equally distributed on the middle portion 21 and the left and right edge portions 22 respectively. A plurality of the second injection holes 232 are provided in the middle interval portion of the nozzle 2, and the second injection holes 232 are equally distributed on the left and right edge portions 22 respectively. In this way, a plurality of them can be arranged according to the area of the nozzle 2 in the middle, and the injection holes 23 are symmetrically arranged at the edges, further ensuring that the injected liquid is ejected more uniformly and consistently from the edges.

[0046] Furthermore, a plurality of the second injection holes 232 are provided in the middle interval portion, and the second injection holes 232 are equally distributed on the middle portion 21 and the left and right edge portions 22 respectively. One of the second injection holes 232 is circular as the center of gravity, and the other second injection holes 232 are symmetrically arranged in the left - right direction with the center of gravity as the center of symmetry. With such an arrangement, the circle of the injection hole 23 is arranged at the center of gravity of the nozzle 2, further ensuring that the range of the injected liquid ejected from the center is more uniform.

[0047] In addition, a plurality of the injection holes 23 include third injection holes 233 that are simultaneously in the lower interval portion and the middle portion 21, and fourth injection holes 234 that are simultaneously in the lower interval portion and the edge portions 22. Among them, the aperture of the third injection hole 233 is smaller than that of the fourth injection hole 234. In this way, the aperture at the edge is set smaller, which is more conducive to allowing more of the injected liquid to be ejected from the middle. The fourth injection hole 234 can be above the third injection hole 233 in height.

[0048] Furthermore, 0.1 ≤ D1 ≤ 0.12 mm for the aperture of the third injection hole 233; and / or 0.15 ≤ D3 ≤ 0.2 mm for the aperture of the fourth injection hole 234. It is preferred within this range, which can ensure that the injected liquid can be ejected in the area of the current nozzle 2, and setting a difference between the third injection hole 233 and the fourth injection hole 234 can make the injection more uniform.

[0049] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
