Abstract
Description
Technical Field
[0001] The present invention relates to the field of atomization technology, in particular to an atomization device. Background Art
[0002] Aerosol is a colloidal dispersion system formed by small solid or liquid particles dispersed and suspended in a gas medium. Since aerosol can be absorbed by the human body through the respiratory system, it provides users with a new alternative absorption method. For example, atomization devices that generate aerosols from aerosol matrices such as medical liquids can be used in different fields such as medicine to deliver inhalable aerosols to users, replacing conventional product forms and absorption methods.
[0003] Specifically, the atomization device can use heating, ultrasound, airflow impact, electrospray and other methods to form an aerosol-generating matrix into an aerosol. The effective ingredients in the aerosol-generating matrix will enter the oral cavity with the aerosol. The effective ingredients in the aerosol will be deposited in the lungs and then absorbed into the human body, thereby realizing substance transfer.
[0004] Since the propagation and deposition processes of aerosol particles of different sizes in the human body are different, and the particle size and distribution of aerosol particles formed by different atomization methods are also different, how to accurately regulate the particle size of aerosol particles inhaled into the human body, effectively control the deposition position of aerosol particles in the human body, improve the utilization efficiency of the effective ingredients in the aerosol, and reduce unnecessary losses is one of the problems that technicians in this field are currently working to solve.
[0005] Existing particle size control technologies usually attempt to control the particle size of aerosol particles by introducing air dilution, impacting the aerosol system, or secondary heating. However, the adjustment process of the above-mentioned adjustment methods is random and the adjustment efficiency is low, making it difficult to accurately control the process of particle size change, thereby failing to effectively improve the utilization rate of the effective ingredients in the aerosol, which is not conducive to the further promotion and application of atomization technology. Summary of the Invention
[0006] Based on this, it is necessary to provide an atomizing device to address the problems of low particle size adjustment efficiency of aerosol particles and low utilization rate of effective ingredients in aerosols. The atomizing device can achieve the technical effect of improving the particle size adjustment efficiency of aerosol particles and improving the utilization rate of effective ingredients in aerosols.

[0016] In one embodiment, the spoiler includes three spoiler segments.
[0017] In one embodiment, the inner diameter of the end of the air outlet connected to the flow spoiler gradually decreases along the conveying direction of the aerosol output channel.
[0018] In one embodiment, the aerosol flowing into the spoiler is divided and flows toward the air inlet end of each spoiler segment, and all the spoiler segments extend spirally around the same central axis.
[0019] In one embodiment, the flow-disturbing portion includes at least two flow-disturbing segments, and the aerosol flowing into the flow-disturbing portion is split and flows toward the air inlet end of each of the flow-disturbing segments.
[0020] In one embodiment, the air inlet and the air outlet are arranged in a straight line along a first direction, and all the spoiler sections are evenly arranged with the first direction as the center.
[0021] In one embodiment, the air outlet ends of at least some of the spoiler sections are combined.
[0022] In one embodiment, the aerosol output channel includes a plurality of spoilers arranged in series and a connecting portion connecting two adjacent spoilers, and the aerosols flowing out of all the spoiler segments in the previous spoiler are mixed at the connecting portion and diverted to flow into the next spoiler.
[0023] In one embodiment, the spoiler includes two spoiler segments symmetrically arranged about a symmetry axis, each spoiler segment is configured as an arc segment communicating between the air inlet and the air outlet, and center lines of the air outlet ends of the two spoiler segments intersect with the symmetry axis;
[0024] Wherein, the symmetry axis coincides with the central axis of the air outlet and the air inlet.
[0025] In one embodiment, each of the spoiler segments includes a first arcuate subsegment, a straight subsegment, and a second arcuate subsegment sequentially connected between the air outlet and the air inlet, one end of the second arcuate subsegment connected to the air outlet is defined as an air outlet end, and the air outlet ends of two second arcuate subsegments are arranged opposite to each other; or

[0029] In one embodiment, the air intake heating assembly includes one or more of a heating tube, a resistance wire, and a heating plate.
[0030] The above-mentioned atomizing device, since the extension direction of at least part of the aerosol output channel intersects with the air inlet direction and / or the air outlet direction of the aerosol output channel, the aerosol particles flowing through the aerosol output channel undergo irregular motion, thereby increasing the probability of aerosol particles colliding with each other, and aerosol particles with smaller particle sizes combine to form aerosol particles with larger particle sizes, thereby effectively reducing the proportion of aerosol particles with particle sizes of approximately 0.62μm and 0.78μm, and increasing the proportion of aerosol particles with a particle size of approximately 1.32μm (greater than 20%).

[0040] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0041] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.
[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.
[0043] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components, unless otherwise specified.

[0045] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.
[0046] As described in the background, aerosol particles of different sizes undergo different propagation and deposition processes within the human body. Aerosols formed using different atomization methods also have varying particle sizes and distributions, leading to varying absorption efficiencies for the active ingredients in the aerosols. Aerosol particles are absorbed more slowly in the respiratory tract, such as the mouth, nose, and throat, leading to the loss of active ingredients. Only particles that enter the bronchi and lungs can be effectively deposited and absorbed, and at a faster rate, ensuring full absorption of the active ingredients in the aerosols.
[0047] Through research, the inventors found that aerosol particles with a particle size greater than 10 μm tend to deposit in the oral cavity, aerosol particles with a particle size of 7-10 μm tend to deposit in the nose, aerosol particles with a particle size of 5-7 μm tend to deposit in the throat, aerosol particles with a particle size of 3-5 μm tend to deposit in the trachea and main bronchi, aerosol particles with a particle size of 1-3 μm tend to deposit in the bronchioles in the lungs, and aerosol particles with a particle size of less than 1 μm tend to enter the alveoli. This shows that aerosol particles with a particle size greater than 5 μm are easily lost in the respiratory tract and oral cavity and have difficulty reaching the lungs. Aerosol particles with a particle size of less than 1 μm, although they easily enter the lungs, have a low deposition efficiency in the lungs and are easily exhaled out of the body with the airflow.
[0048] Therefore, in order to achieve a higher utilization rate of the active ingredients in the aerosol, the optimal particle size of the aerosol particles should be controlled between 1μm and 5μm, so that the aerosol particles have a higher deposition efficiency in the lungs, thereby reducing the dosage of the aerosol-generating matrix, improving the safety of the nebulizer device, and protecting human health to a greater extent.
[0049] However, currently, atomization devices usually use heating atomization, ultrasonic mesh vibration atomization or air flow impact to generate aerosol from the aerosol-generating matrix.
[0050] The particle size of aerosol particles produced by heating atomization is primarily below 1 μm, making them less likely to settle in the mouth and respiratory tract and more likely to enter the lungs. However, particles smaller than 1 μm have a lower deposition efficiency in the lungs and are easily exhaled, resulting in a lower utilization rate of the active ingredients in the aerosol.
[0051] The particle size of aerosol particles generated by ultrasonic sieve vibration atomization or airflow impact is mainly distributed above 5μm, which is more likely 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 reaches the lungs, thus affecting the utilization rate of the effective ingredients in the aerosol.
[0052] Therefore, in order to increase the proportion of aerosol particles with a particle size range of 1μm to 5μm and improve the probability of aerosol particles depositing in the lungs, the present application provides a nebulizer that can purposefully control the growth process of aerosol particles, increase the probability of aerosol particles colliding with each other, and control the particle size of most aerosol particles within 1μm to 5μm, thereby improving the utilization rate of the effective ingredients in the aerosol.
[0053] like Figure 1 and Figure 2 As shown, the atomizing device 100 of the present application comprises an air inlet channel 150 (not shown), an atomizing chamber 130 (not shown), and an aerosol output channel 110. The air inlet channel 150, the atomizing chamber 130, and the aerosol output channel 110 are sequentially connected, and both the air inlet channel 150 and the aerosol output channel 110 are connected to the external environment. An atomizing assembly for atomizing an aerosol-generating substrate to generate an aerosol is provided in the atomizing chamber 130. All gas flowing into the aerosol output channel 110 passes through the atomizing chamber 130. The conveying direction of at least a portion of the aerosol output channel 110 is different from the air inlet direction of the aerosol output channel 110, and / or the conveying direction of at least a portion of the aerosol output channel 110 is different from the air outlet direction of the aerosol output channel 110.
[0054] In this manner, external air enters the atomization chamber 130 from the air inlet channel 150, then carries the aerosol generated by the atomization of the aerosol-generating matrix in the atomization chamber 130 into the aerosol output channel 110, and finally flows out of the aerosol output channel 110 for inhalation by the user. Because the transport direction of at least a portion of the aerosol output channel 110 is different from the air inlet direction and / or the air outlet direction of the aerosol output channel 110, the aerosol particles flowing through the aerosol output channel 110 experience irregular motion, thereby increasing the probability of aerosol particles colliding with each other. Smaller aerosol particles combine to form larger aerosol particles, thereby effectively reducing the proportion of aerosol particles with a particle size of approximately 0.62 μm and 0.78 μm, and increasing the proportion of aerosol particles with a particle size of approximately 1.32 μm (to greater than 20%). Therefore, the particle size of the aerosol particles output by the atomizing device 100 of the present application is mostly 1 μm-5 μm, so it has a high lung deposition rate, effectively improves the effective utilization of the active ingredients in the aerosol, and is conducive to the further promotion and application of atomization technology (such as Figure 6 、 Figure 7 shown).
[0055] It should be noted that the air inlet 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, the air outlet 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 external environment, and the transport 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 tangent direction of any point on the line is the transport direction at that point.
[0056] Specifically, the aerosol output channel 110 is constructed as an air inlet 112, a flow spoiler 114, and an air outlet 116, which are sequentially arranged along the aerosol flow direction. The air inlet 112, the flow spoiler 114, and the air outlet 116 are sequentially connected, and the flow spoiler 114 is constructed as a tortuous channel connected between the air inlet 112 and the air outlet 116. Furthermore, the air inlet 112 and the air outlet 116 are arranged along the first direction (i.e., Figure 1 The spoiler 114 is arranged in a straight line along the left and right direction in the first direction, and the spoiler 114 is arranged in a zigzag manner along the first direction.
[0057] In this way, the spoiler 114 is connected to the atomizing chamber 130 through the air inlet 112, and is connected to the external environment through the air outlet 116. The aerosol in the atomizing chamber 130 enters the spoiler 114 through the air inlet 112, and then flows into the external environment through the air outlet 116. Because 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 always propagating in a straight line. The aerosol particles flowing through the spoiler 114 move irregularly, and the probability of collision between aerosol 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.
[0058] See also Figure 1 、 Figure 2 as well as Figure 3 The aerosol output channel 110 includes a spoiler 114, which includes multiple spoiler segments 1141. All spoiler segments 1141 are arranged in parallel. The aerosol flowing into the spoiler 114 from the air inlet 112 is divided and flows to the air inlet end of each spoiler segment 1141. The air outlet ends of at least some of the spoiler segments 1141 are combined and the aerosol flowing out of the spoiler segments 1141 converges at the air outlet 116. The direction of the air outlet end of at least one spoiler segment 1141 is different from the direction of the air outlet ends of the other spoiler segments 1141, and each spoiler 114 is zigzag along the first direction.
[0059] In this way, the aerosol entering the spoiler from the air inlet 112 enters different spoiler segments 1141 respectively, thereby achieving aerosol diversion and increasing the fluidity of the aerosol particles. During the flow process, the aerosol in each spoiler segment 1141 does not propagate in a straight line, but moves irregularly. The aerosol particles flowing out of the two spoiler segments 1141 in different directions at the air outlet collide with each other, significantly increasing the probability of aerosol particles colliding with each other, thereby increasing the proportion of aerosol particles between 1μm and 5μm, and ultimately accurately improving the probability of aerosol deposition in the lungs. Among them, the movement modes of the aerosol include but are not limited to eddy currents, spoilers, and turbulence.
[0060] Furthermore, if Figure 2 As shown, in the first embodiment of the present invention, the spoiler 114 includes three spoiler segments, and the aerosol flowing into the spoiler 114 is divided and flows toward the air inlet end of each spoiler segment. All the spoiler segments extend spirally around the same central axis, and each spoiler segment itself extends spirally around a central axis, and the above central axes all extend along the first direction.
[0061] In this manner, aerosol entering the spoiler section from the air inlet 112 flows in a spiral pattern within the spoiler section, and aerosol particles exiting each spoiler section 1141 are prone to collision, significantly increasing the probability of collision between aerosol particles. It will be appreciated that the number of spoiler sections in the spoiler 114 is not limited to three, and the length, outer diameter, thread lead angle, and other parameters of each spirally extending spoiler section 1141 are not limited and can be configured as needed to meet different requirements.
[0062] In the above embodiment, the inner diameter of the end of the air outlet 116 connected to the flow spoiler 114 gradually decreases along the conveying direction of the aerosol output channel 110, thereby further increasing the collision probability of aerosol particles.
[0063] like Figures 3 to 5 As shown, in the second embodiment of the present invention, the spoiler 114 includes at least one spoiler segment 1141 , and all spoiler segments 1141 are evenly arranged with the first direction as the center, thereby improving the uniformity of the particle size of the aerosol particles.
[0064] Specifically, the spoiler 114 includes two spoiler sections 1141. The aerosol flowing into the spoiler 114 from the air inlet 112 is divided and flows to the air inlet ends of the two spoiler sections 1141. The air outlet ends of the two spoiler sections 1141 are combined, and the aerosol flowing out of the two spoiler sections 1141 converges at the air outlet 116.
[0065] Furthermore, the two spoiler sections 1141 are symmetrically arranged about an axis of symmetry, which extends along the first direction. Each spoiler section 1141 is constructed as an arc-shaped section connecting between the air inlet 112 and the air outlet 116, and the center lines of the air outlet ends of the two spoiler sections 1141 intersect with the axis of symmetry, which extends along the first direction.
[0066] In a preferred embodiment, each spoiler segment 1141 includes a first arcuate subsegment 1141a, a straight subsegment 1141b, and a second arcuate subsegment 1141c, which are sequentially connected between the air outlet 116 and the air inlet 112. The end of the second arcuate subsegment 1141c connected to the air outlet 116 is defined as the air outlet end, and the air outlet ends of the two second arcuate subsegments 1141c are arranged opposite each other. In other embodiments, the centerline of the air outlet end of each second arcuate subsegment 1141c forms an obtuse angle with the central axis of the air outlet 116.
[0067] It is understandable that the shape of the spoiler segment 1141 is not limited. The projection of the spoiler portion 114 formed by the two spoiler segments 1141 on a plane perpendicular to the first direction can be roughly square, spindle, elliptical, circular, etc. with smoothly rounded top angles.
[0068] See also Figure 4 and Figure 5 In some embodiments, the aerosol delivery channel 110 includes multiple spoilers 114 and at least one connecting portion 118. The multiple spoilers 114 are arranged in series along a first direction, each connecting portion 118 connects between two adjacent spoilers 114, and the delivery direction of the connecting portion 118 extends along the first direction. Each spoiler 114 includes at least two spoiler segments 1141. Aerosol flowing into the spoiler 114 from the air inlet 112 is split and flows toward the air inlet end of each spoiler segment 1141. The air outlet ends of the spoiler segments 1141 are combined, and the aerosol flowing out of the spoiler segments 1141 converges at the air outlet 116.
[0069] In this way, the aerosols flowing out of all the spoiler segments 1141 in the previous spoiler 114 are mixed in the connecting portion 118 and diverted to flow into the next spoiler 114. Multiple diversions and mixing can further improve the fluidity and collision probability of the aerosol particles, further increase the proportion of aerosol particles with a particle size of 1μm to 5μm, and thus accurately improve the deposition probability of the aerosol in the lungs.
[0070] It is understandable that the number of the flow-turbulating portions 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 structures of other components of the atomizing device 100 .
[0071] like Figure 3As shown, in some embodiments, the aerosol output channel 110 includes three spoilers 114 and two connecting portions 118. The three spoilers 114 are arranged sequentially along a first direction and connected sequentially through the connecting portions 118. The two spoilers 114 at the head and tail ends are respectively connected to the air inlet 112 and the air outlet 116. Each spoiler 114 includes two spoiler segments 1141 symmetrically arranged about an axis of symmetry.
[0072] In this way, aerosol flowing into the spoiler 114 from the two air inlets 112 is split and flows toward the air inlet ends of the two spoiler sections 1141. The air outlet ends of the two spoiler sections 1141 are combined, and the aerosol flowing out of the two spoiler sections 1141 collide and merge at the air outlet 116. The aerosol entering the spoiler 114 undergoes three splits and three mixings, significantly increasing the probability of aerosol particles colliding with each other.
[0073] like Figure 4 As shown, in some embodiments, the aerosol output channel 110 includes two spoilers 114 and a connecting portion 118. The two spoilers 114 are arranged sequentially along a first direction and interconnected via the connecting portion 118. Each spoiler 114 includes two spoiler segments 1141. Aerosol flowing into the spoiler 114 from the two air inlets 112 is split and flows toward the air inlet ends of the two spoiler segments 1141. The air outlet ends of the two spoiler segments 1141 are combined, and the aerosol flowing out of the two spoiler segments 1141 merges at the air outlet 116. In this way, the aerosol entering the spoiler 114 undergoes two splits and two mixing processes, significantly increasing the probability of collision between aerosol particles.
[0074] In some embodiments, the atomizing device 100 further has an air inlet channel 150 connected to the atomizing chamber 130. The atomizing device 100 further includes an air inlet heating component, which is disposed in the air inlet channel 150. The air inlet heating component is used to heat the air inlet channel 150, thereby reducing the temperature difference between the air inlet temperature and the heating temperature, thereby increasing the collision probability of the aerosol particles, and thereby reducing the average size of the aerosol particles.
[0075] Specifically, the intake air heating assembly includes one or more of a heating tube, a resistance wire, a mesh or needle-shaped heating plate. It is understood that the heating principle, heating method, and specific structure of the intake air heating assembly are not limited and can be configured according to the structure of the intake passage 150 to meet different installation and heating requirements.
[0076] The airflow process of the atomizing device 100 is as follows:
[0077] The external airflow first enters the air inlet channel 150 , is heated by the air inlet heating component, and then enters the atomizing chamber 130 , enveloping the aerosol generated by the atomizing component in the atomizing chamber 130 and entering the aerosol output channel 110 .
[0078] The aerosol particles entering the spoiler 114 of the aerosol output channel 110 move along the conveying direction of the spoiler 114 , collide with each other during the movement, and combine to form aerosol particles with a particle size of 1 μm-5 μm, and then are discharged from the air outlet 116 .
[0079] The aforementioned atomizer device 100, by providing a flow disruptor 114 in the aerosol output channel 110, achieves aerosol diversion, transmission, and offset, increasing the probability of aerosol particles colliding with each other, effectively controlling the aerosol growth process, and maintaining the aerosol particle size within an ideal range. This improves the deposition efficiency of aerosol particles in the lungs, thereby increasing the utilization rate of the active ingredients in the aerosol-generating matrix. It can also reduce the dosage of the aerosol-generating matrix, improve the safety of the atomizer device, and protect human health to a greater extent. Furthermore, heating the air inlet channel 150 in conjunction with the air inlet heating assembly can further increase the probability of aerosol particles colliding with each other and further improve the accuracy of aerosol particle size control, thereby facilitating the further promotion and application of atomization technology.
[0080] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0081] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
