As used herein, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions are for the purpose of illustration only and are not intended to represent the only embodiment.

As mentioned in the background technology, the propagation and deposition processes of aerosol particles of different sizes in the human body are not the same, and the particle size and distribution of aerosols formed by different atomization methods are also different, resulting in aerosol The absorption efficiencies of active ingredients vary. Among them, the absorption rate of aerosol particles in the mouth, nose, throat and other respiratory tracts is relatively slow, and it is easy to lose the active ingredients in the aerosol. Only the aerosol particles entering the bronchi and lungs can be effectively deposited and absorbed, and the absorption rate is relatively fast. , the active ingredients in the aerosol can be fully absorbed.

The inventors have found through research that aerosol particles with a particle size greater than 10 μm are easily deposited in the oral cavity, aerosol particles with a particle size of 7 μm-10 μm are easily deposited in the nose, and aerosol particles with a particle size of 5 μm-7 μm are easily deposited in the throat. Deposition, aerosol particles with a particle size of 3 μm-5 μm are easy to deposit in the trachea and main bronchus, aerosol particles with a particle size of 1 μm-3 μm are easy to deposit in the bronchioles in the lungs, and aerosol particles with a particle size of less than 1 μm are easy to enter in the alveoli. It can be seen that aerosol particles with a particle size greater than 5 μm are easily lost in the respiratory tract and oral cavity and difficult to reach the lungs, while aerosol particles with a particle size of less than 1 μm can easily enter the lungs, but their deposition efficiency in the lungs is low. It is easily exhaled out of the body with the airflow.

Therefore, in order to have a higher utilization rate of the active ingredients in the aerosol, the optimal particle size of the aerosol particles should be controlled between 1 μm and 5 μm, so that the aerosol particles have a higher deposition efficiency in the lungs, Furthermore, the dosage of the aerosol-generating substrate can be reduced, the safety of the atomization device can be improved, and human health can be protected to a greater extent.

However, at present, atomization devices usually use heating atomization, ultrasonic mesh vibration atomization or airflow impact to generate aerosol from the aerosol-generating substrate.

Among them, the particle size of aerosol particles produced by heating and atomization is mainly below 1 μm, so it is not easy to deposit in the oral cavity and respiratory tract and enter the lungs more easily. However, the deposition efficiency of particles below 1 μm in the lungs is low, and they are easily exhaled out of the body with the airflow, so the utilization rate of the active ingredients in the aerosol is low.

The particle size of the aerosol particles produced by ultrasonic mesh vibration atomization or airflow impact is mainly distributed above 5 μm, and it is easier to deposit in the oral cavity. Therefore, most of the aerosol particles are lost in the respiratory tract and oral cavity, and only a small part can reach them. Lungs, thus affecting the utilization of active ingredients in the aerosol.

Therefore, in order to increase the proportion of aerosol particles with a particle size in the range of 1 μm to 5 μm and increase the probability of aerosol particles being deposited in the lungs, the present application provides an atomization device, which can purposefully control the aerosol particles. The growth process of aerosol particles increases the probability of aerosol particles colliding with each other, and controls the particle size of most aerosol particles within 1 μm to 5 μm, thereby improving the utilization rate of active ingredients in aerosols.

As shown in Figures 1 and 2, the atomizing device 100 of the present application has an air inlet channel 150 (not shown in the figure), an atomization chamber 130 (not shown in the figure) and an aerosol output channel 110, the air inlet channel 150, the atomizer The cavity 130 and the aerosol output channel 110 are connected in sequence, and the air inlet channel 150 and the aerosol output channel 110 are all connected to the external environment. The atomization chamber 130 is provided with an atomization component for atomizing the aerosol generating substrate to generate an aerosol , the gas flowing into the aerosol output channel 110 all passes through the atomization chamber 130 . Wherein, the delivery direction of at least part of the aerosol output channels 110 is different from the air intake direction of the aerosol output channel 110 , and/or the delivery direction of at least part of the aerosol output channels 110 is different from the air outlet direction of the aerosol output channel 110 .

In this way, outside air enters the atomization chamber 130 from the air inlet channel 150, and then carries the aerosol generated by the atomization of the aerosol-generating substrate in the atomization chamber 130 into the aerosol output channel 110, and finally flows out from the aerosol output channel 110 for The user inhales. Since the delivery direction of at least part of the aerosol output channel 110 is different from the air intake direction and/or the air output direction of the aerosol output channel 110, the aerosol particles flowing through the aerosol output channel 110 undergo irregular movements, thereby increasing the aerosol flow rate. The probability of particles colliding with each other, aerosol particles with smaller particle size combine to form aerosol particles with larger particle size, thus effectively reducing the proportion of aerosol particles with a particle size of about 0.62 μm and 0.78 μm, and increasing the particle size by about The proportion of aerosol particles of 1.32 μm (greater than 20%). Therefore, the particle size of the aerosol particles output by the atomization device 100 of the present application is mostly 1 μm-5 μm, so it has a higher lung deposition rate, effectively improves the effective utilization of active ingredients in the aerosol, and is conducive to atomization Further popularization and application of technology (as shown in Figure 6 and Figure 7).

It should be noted that the air intake direction of the aerosol output channel 110 is the flow direction of the airflow at the connection between the aerosol output channel 110 and the atomization chamber 130, and the air outlet direction of the aerosol output channel 110 is the direction between the aerosol output channel 110 and the outside world. The flow of the airflow at the junction of the environment, the delivery direction of the aerosol output channel 110 is the flow direction of the aerosol at any position in the length direction of the aerosol output channel 10, if the aerosol output channel 110 is regarded as a line, then the line The tangent direction at any point above is the conveying direction at that point.

Specifically, the aerosol output channel 110 is configured as an air inlet 112, a spoiler 114, and an air outlet 116 arranged in sequence along the aerosol flow direction, and the air inlet 112, the spoiler 114, and the air outlet 116 are connected in sequence, and the spoiler The flow portion 114 is configured as a meandering passage connected between the air inlet 112 and the air outlet 116 . Further, the air inlet 112 and the air outlet 116 are linearly arranged along the first direction (ie, the left-right direction in FIG. 1 ), and the spoiler 114 is arranged in a zigzag manner along the first direction.

In this way, the spoiler 114 communicates with the atomization chamber 130 through the air inlet 112 , the spoiler 114 communicates with the external environment through the air outlet 116 , the aerosol in the atomization chamber 130 enters the spoiler 114 through the air inlet 112 , It then flows into the external environment through the air outlet 116 . Since the spoiler 114 is configured as a tortuous channel connected between the air inlet 112 and the air outlet 116, the aerosol is prevented from propagating in a straight line all the time, and the aerosol particles flowing through the spoiler 114 move irregularly, and the air The probability of mutual collision between the sol particles is significantly increased, thereby increasing the number of particles with a particle size between 1 μm and 5 μm, thereby improving the effective utilization of the active ingredients in the aerosol.

In this way, the aerosol entering the spoiler section from the air inlet 112 respectively enters into different spoiler sections 1141 , so as to achieve split flow of the aerosol and increase the fluidity of the aerosol particles. The aerosol in each spoiler section 1141 does not travel along a straight line but moves irregularly during the flow process, and the aerosol particles flowing out from the two spoiler sections 1141 in different directions of the gas outlet are opposed, thereby significantly increasing the The probability of aerosol particles colliding with each other increases the proportion of aerosol particles from 1 μm to 5 μm, and finally precisely increases the probability of aerosol deposition in the lungs. Among them, the movement mode of aerosol includes but not limited to eddy current, turbulent flow and turbulent flow.

All spoiler segments extend helically around the same central axis, and each spoiler segment itself extends spirally around a central axis, and the central axes all extend along the first direction.

In this way, the aerosol entering the spoiler section from the air inlet 112 flows spirally in the spoiler section, and the aerosol particles flowing out from each spoiler section 1141 are likely to collide, thereby significantly increasing the probability of the aerosol particles colliding with each other . It can be understood that the number of turbulence segments in the turbulence portion 114 is not limited to three, and parameters such as the length, outer diameter, and thread lead angle of each helically extending turbulence segment 1141 are not limited, and can be set according to needs to meet different requirements.

In the above embodiment, the inner diameter of the end of the air outlet 116 connected to the spoiler 114 decreases gradually along the delivery direction of the aerosol output channel 110 , so as to further increase the collision probability of the aerosol particles.

As a preferred embodiment, each spoiler segment 1141 includes a first arc sub-section 1141a, a straight line sub-section 1141b and a second arc sub-section 1141c sequentially connected between the air outlet 116 and the air inlet 112, The end of the second arc-shaped subsection 1141c connected to the air outlet 116 is defined as an air outlet, and the air outlets of the two second arc-shaped subsections 1141c are arranged opposite to each other. In some other embodiments, the central line of the air outlet end of each second arc-shaped subsection 1141c forms an obtuse angle with the central axis of the air outlet 116 .

It can be understood that the shape of the spoiler section 1141 is not limited, and the projection of the spoiler portion 114 formed by the two spoiler sections 1141 on a plane perpendicular to the first direction can be roughly a square, a shuttle, or an ellipse with a smooth transition at the apex. shape, circle etc.

In this way, the aerosols flowing out of all the spoiler sections 1141 in the previous spoiler 114 are mixed at the connection part 118 and diverted into the next spoiler 114. Multiple diversion and mixing can further improve the fluidity and The collision probability further increases the proportion of aerosol particles with a particle size of 1 μm to 5 μm, thereby precisely increasing the probability of aerosol deposition in the lungs.

It can be understood that the number of spoilers 114 in the aerosol output channel 110 is not limited, and can be set according to factors such as the length and inner diameter of the aerosol output channel 110 and the configuration of other components of the atomizing device 100 .

As shown in FIG. 3 , in some embodiments, the aerosol output channel 110 includes three spoilers 114 and two connecting parts 118 , the three spoilers 114 are sequentially arranged along the first direction and communicated in sequence through the connecting parts 118 , the two spoilers 114 located at both ends of the head and the tail communicate with the air inlet 112 and the air outlet 116 respectively. Each spoiler 114 includes two spoiler sections 1141 arranged symmetrically about a symmetry axis.
