Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an atomizing cup that can adapt to three-dimensional all-round postures, including forward, side and inverted postures, continuously generate atomization effect and prevent drug spillage, significantly improving user comfort and atomization efficiency. Background Technology

[0002] Medical nebulizers are devices used to treat upper respiratory tract diseases, requiring stable spray, fine and uniform droplets, and high nebulization efficiency during operation. In use, medication is poured into the nebulization cup, and the relevant nebulizing device or an external compressor nebulizer is activated to deliver a continuous airflow into the cup. This airflow then outputs the atomized fine droplets, completing the nebulization of the medication within the cup. However, existing technologies have the following drawbacks: Because the medication within the nebulization cup is fluid, the patient needs to maintain a specific posture during treatment to keep the medication within the effective nebulization area. Therefore, patients often need to maintain a seated position for extended periods, leading to fatigue and discomfort. Furthermore, nebulization is difficult to achieve when changing posture or not sitting, and medication spillage or lack of nebulization is common. For example, children jumping around or bedridden patients being placed sideways may hinder the achievement of the desired nebulization effect. Summary of the Invention

[0003] This invention addresses the shortcomings and deficiencies of existing technologies by proposing an atomizing cup that can adapt to all three-dimensional postures, including forward, sideways, and inverted postures, continuously generate atomization while preventing liquid spillage, and significantly improve user comfort and atomization effect.

[0004] This utility model achieves its purpose through the following measures:

[0005] An atomizing cup has a shell with a hollow cavity for storing liquid medicine. The lower end of the shell has an air inlet, and the top of the shell has an air outlet channel opposite to the air inlet. The shell is characterized by having a liquid medicine absorption and atomization assembly, which includes an atomization chamber coaxially arranged with the air inlet and air outlet channel on the shell. The bottom of the atomization chamber is connected to the air inlet of the shell. The atomization chamber is conical in shape, and the bottom of the atomization chamber is connected to two or more liquid inlet pipes. The liquid inlet ends of the two or more liquid inlet pipes are located at different heights on the inner wall of the shell space.

[0006] The shell of this invention has a funnel-shaped lower shell, so that the liquid medicine inside the shell settles to a minimum at the bottom of the shell.

[0007] This invention features two or more inlet pipes that are radially connected to the bottom of the atomizing chamber inside the housing. The inlet ports of the inlet pipes are located at the bottom, side wall, and top of the housing. By using inlet pipes of varying lengths that are radially connected to the bottom of the atomizing chamber, it can be ensured that when the housing is in different positions, the liquid medicine in the hollow cavity of the housing can be delivered into the atomizing chamber through at least one inlet pipe.

[0008] This utility model has two or more liquid inlet pipes with radial openings located on the bottom outer side, side wall and top of the atomizing chamber inside the shell. The liquid inlet pipes are connected to the bottom of the atomizing chamber in different placement states through multiple planar openings of varying lengths.

[0009] The present invention describes two or more liquid inlet pipes that extend vertically or in a curved manner along the inner wall of the shell, forming a sleeve-shaped main body. Each liquid inlet pipe in the sleeve-shaped main body has an inlet port at its upper end, and the heights of the two or more inlets are not the same.

[0010] The present invention describes two or more liquid inlet pipes that extend upward along the inner wall of the shell, either vertically or in a curved manner. Furthermore, the two or more liquid inlet pipes that extend vertically or in a curved manner along the inner wall of the shell form a sleeve-shaped main body. Each liquid inlet pipe in the sleeve-shaped main body has a liquid inlet at its upper end, and the two or more liquid inlets are located in different spatial positions.

[0011] The housing of this utility model is further provided with an annular and upwardly convex baffle distributed around the upper outlet of the atomizing chamber to prevent un-atomized liquid from entering the area above the atomizing chamber. Furthermore, the housing is formed by fastening an upper housing and a lower housing together, with the upper housing fastened to the outside of the lower housing. The lower housing is funnel-shaped to allow large-particle liquid to flow back into the liquid chamber. An air outlet channel is opened at the top of the upper housing, and a cylindrical exhaust sleeve is provided inside the upper housing corresponding to the exhaust channel. The lower end of the exhaust sleeve is connected to the upper port of the atomizing chamber. The annular baffle distributed around the upper outlet of the atomizing chamber can be set on the inner wall of the upper housing. When the device is inverted, the funnel-shaped part of the lower housing can also act as the inner wall of the atomizing cup to prevent liquid leakage.

[0012] The atomizing chamber of this invention is composed of two conical sections connected together. The bottom radius of the lower first conical section is greater than that of the upper second conical section, thus forming an atomizing chamber body that is narrow at the top and wide at the bottom with a constricted opening. This is beneficial for increasing the gas flow rate and reducing gas turbulence, thereby improving the atomization effect.

[0013] The liquid atomizing assembly of this utility model has two or more inlet pipes with at least three different lengths. Furthermore, at least two sets of inlet pipes with three different lengths are arranged radially around the atomizing cavity.

[0014] The upper end of the atomizing chamber of this utility model is also provided with a droplet separator. The droplet separator is set on the air outlet of the atomizing chamber. The droplet separator includes at least one crossbeam that overlaps with the diameter of the air outlet of the atomizing chamber, so as to prevent excessively large droplets from overflowing at the outlet of the atomizing chamber.

[0015] Compared with the prior art, this utility model utilizes two or more radially distributed liquid inlet channels with different spatial openings within the shell to absorb the liquid medicine in different areas of the shell. In the working state, the atomizing chamber is under negative pressure in various placement states, so that the liquid medicine is continuously fed into the atomizing chamber under the action of negative pressure airflow. Then, the airflow in the atomizing chamber breaks the liquid medicine into droplets, and the droplets are sent out of the atomizing chamber with the airflow. During this process, excessively large droplets are screened and intercepted by the droplet separator at the air outlet of the atomizing chamber to improve the absorption effect of the final output droplets.

[0016] This invention overcomes the problems of existing nebulizer cups, such as failure to atomize under different placement conditions, easy leakage of medication, and patient fatigue. It has significant advantages such as reasonable structure and convenient use. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0022] As attached Figure 1As shown, this example proposes an atomizing cup with a reasonable structure, convenient use, and the ability to continuously generate atomization in three dimensions (front, side, and inverted) while preventing the liquid from overflowing, significantly improving user comfort and atomization efficiency. It has a shell with a hollow cavity for storing the liquid. The lower end of the shell has an air inlet 1, and the top of the shell has an air outlet channel 2 opposite to the air inlet 1. The shell is equipped with a liquid absorption and atomization component, which includes an atomization chamber 3 coaxially arranged with the air inlet 1 and the air outlet channel 2 on the shell. The bottom of the atomization chamber 3 is connected to the air inlet 1 of the shell. The atomization chamber 3 is conical in shape, and the bottom edge of the atomization chamber 3 is connected to two or more liquid inlet pipes 4. The two or more liquid inlet pipes 4 extend along the inner wall of the shell, and the spatial opening positions of the two or more liquid inlet pipes 4 are not the same.

[0023] In this example, the shell has a funnel-shaped lower shell 5, so that the liquid medicine inside the shell is kept to a minimum at the bottom of the shell. Two or more liquid inlet pipes 4 are arranged radially on the outside of the bottom of the atomizing chamber 3 inside the shell. Through the liquid inlet pipes 4 of different lengths that are radially connected to the bottom of the atomizing chamber, it can be ensured that when the shell is in different positions, the liquid medicine in the hollow cavity of the shell can be sent into the atomizing chamber 3 through at least one liquid inlet pipe 4.

[0024] In this example, the housing is also provided with annular and upward-convex baffles 6 distributed around the upper outlet of the atomizing chamber 3 to prevent un-atomized liquid from entering the area above the atomizing chamber. Furthermore, the housing is formed by fastening an upper housing 7 and a lower housing 5 together. The upper housing 7 is fastened to the outside of the lower housing 5. The lower housing is funnel-shaped. An air outlet channel 2 is opened at the top of the upper housing 7. A cylindrical exhaust sleeve is provided inside the upper housing corresponding to the air outlet channel. The lower end of the exhaust sleeve is connected to the upper port of the atomizing chamber. The annular baffles 6 distributed around the upper outlet of the atomizing chamber 3 can be set on the inner wall of the upper housing.

[0025] As attached Figure 2 As shown, the atomizing chamber 3 in this example is composed of two conical sections connected together. The bottom radius of the first conical section located below is greater than that of the second conical section located above, thus forming an atomizing chamber body that is narrow at the top and wide at the bottom with a constricted structure. This is beneficial for increasing the gas flow rate and reducing gas turbulence, thereby improving the atomization effect.

[0026] In this example, the liquid atomizing assembly has two or more liquid inlet pipes 4, each with at least three different spatial opening positions. Furthermore, at least two sets of liquid inlet pipes 4 with three different spatial opening positions are arranged radially around the atomizing chamber.

[0027] In this example, the upper end of the atomizing chamber 3 is also provided with a droplet separator 8. The droplet separator 8 is set on the air outlet of the atomizing chamber. The droplet separator 8 includes at least one crossbeam that overlaps with the diameter of the air outlet of the atomizing chamber, so as to prevent excessively large droplets from overflowing at the outlet of the atomizing chamber.

[0028] Compared with existing technologies, this example utilizes two or more radially distributed liquid inlet channels with different spatial opening positions within the housing to absorb the liquid medicine in different areas of the housing. In operation, the atomizing chamber is under negative pressure, which allows the liquid medicine to be continuously fed into the atomizing chamber under the negative pressure of the airflow. The airflow within the atomizing chamber then breaks the liquid medicine into droplets, which are then carried out of the atomizing chamber by the airflow. During this process, excessively large droplets are filtered and intercepted by the droplet separator at the air outlet of the atomizing chamber, thereby improving the absorption effect of the final output droplets. Example

[0029] This example proposes an atomizing cup with a shell having a hollow cavity for storing liquid medicine. The lower end of the shell has an air inlet 1, and the top of the shell has an air outlet channel 2 opposite to the air inlet 1. The shell is equipped with a liquid medicine absorption and atomization assembly, which includes an atomization chamber 3 coaxially arranged with the air inlet 1 and the air outlet channel 2 on the shell. The bottom of the atomization chamber 3 is connected to the air inlet 1 of the shell. The atomization chamber 3 is conical in shape, and the bottom edge of the atomization chamber 3 is connected to two or more liquid inlet pipes 4. The two or more liquid inlet pipes 4 extend along the inner wall of the shell, and the spatial opening positions of the two or more liquid inlet pipes 4 are not the same.

[0030] As attached Figure 3 As shown, in this example, two or more liquid inlet pipes 4 extend vertically upward along the inner wall of the shell to form a cylindrical body. Liquid inlets are opened at the liquid inlet ends of the two or more liquid inlet pipes 4. The heights of the two or more liquid inlets are different to accommodate the absorption of medicine at different depths.

[0031] This invention overcomes the problems of existing nebulizer cups, such as failure to atomize under different placement conditions, easy leakage of medication, and patient fatigue. It has significant advantages such as reasonable structure and convenient use.
