Description

Technical Field:

[0001] The present invention relates to the technical field of medical devices, and specifically relates to an atomizing cup that can adapt to three-dimensional all-round postures, including forward, lateral, and inverted postures, can continuously generate an atomizing effect and prevent liquid medicine from overflowing, and significantly improve the use comfort and atomizing efficiency. Background Art:

[0002] A medical atomizer is a device used to treat upper respiratory diseases, and it is required to have stable spraying, fine, uniform, and highly efficient atomizing droplets during its operation. When a medical atomizer is in use, liquid medicine is poured into the atomizing cup, and relevant atomizing components are started or an external compressed atomizer is started to send a continuous airflow into the atomizing cup, and the atomized fine droplets are output by using the airflow to complete the atomization of the liquid medicine in the atomizing cup. However, in the prior art, there are the following disadvantages and deficiencies: Since the liquid medicine in the atomizing cup has fluidity, during treatment, the patient needs to maintain a specific state to ensure that the liquid medicine is fixed in the effective atomizing area. Therefore, patients often need to maintain a sitting posture for a long time, resulting in fatigue and discomfort; and it is difficult to generate an atomizing effect during the process of changing postures and in non-sitting postures, and it is very easy to occur the situation of liquid medicine overflowing or no atomizing effect, such as the jumping state of children during use, the lateral placement of bedridden patients, etc., which are difficult to achieve the desired atomizing effect. Summary of the Invention:

[0003] The present invention aims at the disadvantages and deficiencies in the prior art, and proposes an atomizing cup that can adapt to three-dimensional all-round postures, including forward, lateral, and inverted postures, can continuously generate an atomizing effect and prevent liquid medicine from overflowing, and significantly improve the use comfort and atomizing effect.

[0004] The present invention is achieved through the following measures:

[0005] An atomizing cup is provided with a housing having a hollow cavity. The hollow cavity of the housing is used for storing liquid medicine. An air inlet hole is provided at the lower end of the housing, and an air outlet channel opposite to the air inlet hole is opened at the top of the housing. The housing is characterized in that it is provided with a liquid medicine suction and atomization assembly. The liquid medicine suction and atomization assembly includes an atomization cavity coaxially arranged with the air inlet hole and the air outlet channel on the housing. The bottom of the atomization cavity is communicated with the air inlet hole of the housing. The atomization cavity is in a conical cylinder shape. The bottom of the atomization cavity is communicated with more than two liquid inlet pipelines, and the liquid inlet ends of the more than two liquid inlet pipelines are located at different heights on the inner wall of the housing space.

[0006] The housing of the present invention has a funnel-shaped lower housing, so that as little liquid medicine as possible in the housing precipitates at the bottom of the housing.

[0007] In the present invention, two or more liquid inlet pipelines are connected to the bottom of the atomization chamber in the housing in a radial manner. The liquid inlet openings of the liquid inlet pipelines are provided at the bottom, side wall and top of the housing. Through the liquid inlet pipelines with different lengths that are connected to the bottom of the atomization chamber in a radial manner, it can be ensured that when the housing is in different postures, the liquid medicine in the hollow cavity of the housing can be sent into the atomization chamber through at least one liquid inlet pipeline.

[0008] In the present invention, the two or more liquid inlet pipelines extend upward along the inner wall of the housing, extending upward vertically or in a curved manner. Further, the two or more liquid inlet pipelines extend vertically or in a curved manner upward along the inner wall of the housing to form a sleeve-shaped main body. The upper end of each liquid inlet pipeline in the sleeve-shaped main body is provided with a liquid inlet opening, and the spatial positions of the two or more liquid inlet openings are inconsistent.

[0009] In the present invention, an annular and upwardly convex baffle is further provided in the housing around the upper end outlet of the atomization chamber to prevent the unatomized liquid medicine from entering the area above the atomization chamber. Further, the housing is formed by buckling an upper housing and a lower housing. The upper housing is buckled outside the lower housing. The lower housing is in a funnel shape for the large-particle liquid medicine to flow back into the liquid medicine bin again. An air outlet channel is provided at the top of the upper housing. A cylindrical exhaust sleeve body is provided in the upper housing corresponding to the air outlet channel. The lower end of the exhaust sleeve body is connected to the upper port of the atomization chamber. The annular baffle around the upper end outlet of the atomization chamber can be provided 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 atomization cup to prevent the liquid medicine from leaking.

[0010] In the present invention, the atomization chamber is formed by connecting two-stage conical barrel-shaped main bodies. The bottom radius of the first conical barrel section located below is larger than the bottom radius of the second conical barrel section located above, so as to form an atomization chamber main body with a narrow upper part and a wide lower part and a necking structure, which is beneficial to improving the gas flow rate and causing gas turbulence, and improving the atomization effect.

[0011] In the liquid medicine atomization assembly of the present invention, two or more liquid inlet pipelines include at least three different lengths. Further, at least two groups of liquid inlet pipelines with three different lengths are distributed around the atomization chamber in a radial manner.

[0012] In the present invention, a liquid droplet separator is further provided at the upper end of the atomization chamber. The liquid droplet separator is arranged on the air outlet hole of the atomization chamber. The liquid droplet separator includes at least one cross beam that overlaps with the diameter of the air outlet hole of the atomization chamber to block the overflow of too large liquid droplets at the outlet of the atomization chamber.

[0013] Compared with the prior art, the present invention utilizes more than two liquid inlet channels with different spatial opening positions radially distributed in the shell to complete the absorption of liquid medicine in different regions within the shell. In the working state, the atomization chamber is in a negative pressure state under various different placement states, so that the liquid medicine is continuously sent into the atomization chamber under the action of the negative pressure of the air flow. Then, under the action of the air flow in the atomization chamber, the liquid medicine is broken into droplets, and the droplets are sent out of the atomization chamber along with the air flow. During this process, the too large droplets are screened and intercepted by the droplet separator at the air outlet of the atomization chamber to improve the absorption effect of the finally output droplets.

[0014] The present invention can overcome the problems of the existing atomization cup that it cannot be atomized when the placement state is changed, it is easy for the liquid medicine to overflow, and it is easy for patients to get fatigued during use. It has remarkable advantages such as reasonable structure and convenient use. Brief Description of the Drawings:

The bottom of the atomization chamber 3 is communicated with the air inlet hole 1 of the shell. The atomization chamber 3 is in a conical cylinder shape, and the bottom edge of the atomization chamber 3 is communicated with more than two liquid inlet pipelines 4. The more than two liquid inlet pipelines 4 extend along the inner wall of the shell, and the spatial opening positions of the more than two liquid inlet pipelines 4 are inconsistent;

[0022] In this example, the housing has a funnel-shaped lower housing 5, so that as little liquid medicine as possible remains at the bottom of the housing. More than two liquid inlet pipelines 4 are radially arranged on the outer side of the bottom of the atomization chamber 3 in the housing.

[0024] As shown in the Figure 2 attachment, in this example, the atomization chamber 3 is formed by connecting two-stage conical cylinder-shaped main bodies. The bottom radius of the first conical cylinder section located below is larger than the bottom radius of the second conical cylinder section located above, so as to form an atomization chamber main body with a narrow upper part and a wide lower part and a necking structure, which is beneficial to increasing the gas flow rate and causing gas turbulence, and improving the atomization effect.

[0025] In the liquid medicine atomization assembly of this example, more than two liquid inlet pipelines 4 at least include three different spatial opening positions. Further, at least two groups of liquid inlet pipelines 4 with three different spatial opening positions are radially distributed around the atomization chamber;

The droplet separator 8 at least includes a cross beam that overlaps with the diameter of the air outlet hole of the atomization chamber to block the overflow of too large droplets at the outlet of the atomization chamber.

[0027] Compared with the prior art, in this example, more than two liquid inlet channels with different spatial opening positions radially distributed in the housing are used to complete the absorption of the liquid medicine in different areas of the housing. In the working state, the atomization chamber is in a negative pressure state, so that the liquid medicine is continuously sent into the atomization chamber under the action of the air flow negative pressure. Then, the liquid medicine is broken into droplets by the action of the air flow in the atomization chamber, and the droplets are sent out of the atomization chamber along with the air flow. During this process, the too large droplets are screened and intercepted by the droplet separator at the air outlet hole of the atomization chamber to improve the absorption effect of the finally output droplets.

An air inlet hole 1 is provided at the lower end of the housing, and an air outlet channel 2 opposite to the air inlet hole 1 is opened at the top of the housing. The housing is provided with a liquid medicine suction and atomization assembly. The liquid medicine suction and atomization assembly includes an atomization cavity 3 coaxially arranged with the air inlet hole 1 and the air outlet channel 2 on the housing. The bottom of the atomization cavity 3 is communicated with the air inlet hole 1 of the housing. The atomization cavity 3 is in a conical cylinder shape. The bottom edge of the atomization cavity 3 is communicated with more than two liquid inlet pipelines 4. The more than two liquid inlet pipelines 4 extend along the inner wall of the housing, and the spatial opening positions of the more than two liquid inlet pipelines 4 are inconsistent.

[0030] As shown in the Figure 3 accompanying drawings, in this example, more than two liquid inlet pipelines 4 extend vertically upward along the inner wall of the housing to form a sleeve-shaped main body. Liquid inlet ports are opened at the liquid inlet ends of the more than two liquid inlet pipelines 4, and the heights of the more than two liquid inlet ports are inconsistent to adapt to the suction of liquid medicine at different depths.
