Description

Technical Field

[0001] The present application relates to the field of atomizers, and in particular to a slow mist atomization device of a compression atomizer. Background Art

[0002] Nebulizer therapy is a common treatment for respiratory diseases. Its principle is to use a nebulizer to atomize a medication solution into inhalable aerosol particles. The aerosol then enters the respiratory tract, achieving therapeutic effects. Nebulizers are categorized by their operating principles into compression nebulizers, micromesh nebulizers, and ultrasonic nebulizers. Compression nebulizers utilize compressed air through a small nozzle to create a high-speed airflow. This negative pressure propels the liquid toward an obstruction, where it passes through a filter structure within the medicine cup, producing inhalable aerosol particles. While compression nebulizers offer greater performance stability than micromesh and ultrasonic nebulizers, the high airflow results in an excessively high initial velocity of the aerosol, resulting in a strong impact and poor absorption, which can affect patient experience and treatment effectiveness.

The small particles in the decelerated medicine mist airflow account for a large proportion and are sprayed from the mist outlet toward the bin cover. After hitting the bin cover, the flow direction is changed and flows to the other end of the mist storage tank.

More external gas enters to balance the negative pressure, thereby reducing the flow rate of the medicine mist. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only some embodiments of the present application, rather than all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application, its application, or use. Example

[0027] This embodiment provides a slow mist atomization device for a compression atomizer, such as Figure 1 、 2 As shown, it includes an upper cup body 1, a lower cup body 2, a nozzle 4, a spacer 5, a compartment cover 6 and an atomizer cup interface 7. The spacer 5 is connected to the upper cup body 1 through the atomizer cup interface 7, and the upper cup body 1 is connected to the lower cup body 2. A compartment cover 6 is provided at one end of the spacer 5 and a nozzle 4 is provided at the other end. The nozzle 4 is connected to a mouthpiece or a mask. The user uses it by wearing a mouthpiece or a mask. A through hole is also provided on the outer shell of the mouthpiece or the mask, and the through hole is used to discharge the gas exhaled by the user.

[0028] like Figure 3-5As shown, an aerosol outlet 101 is provided at one end of the upper cup body 1, and a baffle 3 is fixed to the other end. The lower end of the baffle 3 is placed in the liquid medicine in the lower cup body 2. When the liquid medicine hits the baffle 3, the medicine mist is sprayed out from the lower cup body. An aerosol collection chamber 701 is provided inside the atomizing cup interface. The aerosol collection chamber 701 is connected to the aerosol outlet 101. A liquid collecting tower 704 is provided on the top of the aerosol collection chamber 701 to buffer the medicine mist sprayed from the atomizing cup. A mist outlet 705 is provided next to the liquid collecting tower 704. The mist outlet 705 is connected to the inner cavity of the aerosol storage tank 5.

[0029] During use, the medicine liquid in the lower cup body 2 hits the baffle plate 3 due to the impact of the high-speed airflow at the bottom of the lower cup body 2 to form medicine mist, which is sprayed out from the aerosol outlet 101 to the aerosol collection chamber 701, and then flows to the liquid collecting tower 704 at the top of the aerosol collection chamber 701. The medicine mist hits the liquid collecting tower 704, the airflow velocity of the medicine mist decreases, and large particles of medicine adhere to the liquid collecting tower 704 to gradually form medicine droplets that fall back into the lower cup body 2 from the aerosol outlet 101 and are atomized again. The medicine mist that is not attached to the liquid collecting tower 704 has its speed reduced after the collision, and is sprayed out from the mist outlet 705 next to the liquid collecting tower 704 to the inner cavity of the mist storage tank 5.

[0030] The direction of the mist outlet 705 faces the chamber cover 6, and the medicine mist airflow sprayed from the mist outlet 705 moves toward the chamber cover 6, then hits the chamber cover 6, reduces the speed of the medicine mist airflow again, and then flows toward the nozzle 4. Example

[0031] The technical solution provided in this embodiment is different from that in embodiment 1 in that Figure 5 As shown, the liquid collecting tower 704 is an inverted conical structure, which can have a larger area to receive the impact of the high-speed medicine mist airflow. Large particles adhere to the liquid collecting tower 704, forming medicine droplets at the tip of the cone and falling back into the lower cup body 2.

[0032] like Figure 6 As shown, the bin cover is provided with a M-shaped grille 601, with a cone-shaped hook 603 in the center of the M-shaped grille 601, and a one-way diaphragm 602 is provided on the inner side of the bin cover 6 and fixed by the hook 603. Air can flow in from the bin cover but cannot flow out from the bin cover.

[0033] like Figure 4 、 5As shown, a medicine cup fixing groove 702 is further provided in the atomizing cup interface 7, and an air intake grille 703 is provided on the side wall of the medicine cup fixing groove 702. The air intake grille 703 can adjust the size of the air vent thereon. An air intake compensation port 102 is also provided on one end of the upper cup body 1 provided with an aerosol outlet 101. The air intake compensation port 102 is connected to the medicine cup fixing groove 702. A buckle 103 is also provided near the air intake compensation port 102. The buckle 103 is used to fix the baffle. During operation, the medicine liquid on the baffle collides to form medicine mist, and a negative pressure is generated near the air intake compensation port 102, which absorbs nearby gas. After entering through the through holes of the air intake grille 703, the outside gas enters from the air intake grille 703 and enters the lower cup from the air intake compensation port 102 to balance the partial negative pressure to reduce the initial speed after the medicine mist is formed.

[0034] The spray velocity of the atomized liquid medicine in the lower cup 2 can be adjusted by adjusting the size of the vent holes in the air intake grille 703. When the vent holes in the air intake grille 703 are large, the lower cup 2 generates a high-speed mist flow due to the liquid medicine hitting the baffle 3, creating a negative pressure inside the lower cup 2. External air enters the air intake compensation port through the air intake grille 703 and then enters the lower cup 2, partially balancing the negative pressure and reducing the spray velocity of the mist.

[0035] like Figure 7 As shown, the aerosol outlet 101 on the upper cup body is connected to the aerosol collecting chamber 701. The medicine mist airflow generated by the lower cup body 1 is ejected from the aerosol outlet 101 to the aerosol collecting chamber 701, and then hits the liquid collecting tower to decelerate, and then ejected from the mist outlet. At this time, the medicine mist airflow is lower than the speed of the aerosol outlet 101, and the aerosol collecting chamber 701 can store the medicine mist airflow.

[0036] The air inlet compensation port 102 is connected to the medicine cup fixing groove 702. Air entering through the air inlet grille enters the lower cup body 2 through the air inlet compensation port 102, partially balancing the negative pressure and reducing the initial velocity of the medicine mist output from the baffle. The medicine mist ejected from the mist outlet 705 enters the inner cavity of the spacer 5, flows toward the chamber cover 6, and decelerates after impacting the chamber cover 6. It then flows toward the nozzle 4 and enters the user's body.

[0037] After being decelerated by the liquid collecting tower 704 and the chamber cover 6, the speed of the medicine mist airflow is smoother, and small particles account for a large proportion in the medicine mist airflow. After entering the user's body, it will not cause discomfort due to the excessive flow speed. The small particles act on the user's body and are absorbed faster and more easily, and the therapeutic effect is more efficient.

[0038] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
