Atomizing components and atomizers

Abstract

This invention relates to an atomizing component and an atomizer. The atomizing component includes a support body, an ultrasonic atomizing plate, a first elastic fin, and a second elastic fin. The support body supports and connects the first and second elastic fins, which are arranged facing each other and clamping the ultrasonic atomizing plate. Both the first and second elastic fins have deformation spaces on their sides facing away from the ultrasonic atomizing plate. When the ultrasonic atomizing plate vibrates along its own axial direction to atomize the aerosol-generating matrix, the deformation space behind the first elastic fin allows it to float back and forth with the ultrasonic atomizing plate, and the deformation space behind the second elastic fin allows it to float back and forth with the ultrasonic atomizing plate. The ultrasonic atomizing plate can vibrate adaptively, reducing noise during vibration, lowering friction, reducing heat generation, and preventing the efficacy of the aerosol-generating matrix from being compromised.

Description

Technical Field

[0001] This invention relates to the field of atomization technology, and in particular to atomization components and atomizers. Background Technology

[0002] Aerosols are colloidal dispersion systems formed by the dispersion and suspension of solid or liquid particles in a gaseous medium. Because aerosols can be absorbed by the human body through the respiratory system, they provide users with a novel alternative absorption method. For example, electronic atomization devices that generate aerosols by heating liquid or solid aerosol-generating matrices are applied in various fields to deliver inhalable aerosols to users, replacing conventional product forms and absorption methods.

[0003] Generally, nebulizers atomize aerosol-generating matrices, which are matrix materials that produce aerosols after atomization. In related technologies, nebulizers atomize the aerosol-generating matrices by heating or by ultrasonic vibration. For ultrasonic nebulizers, the aerosol-generating matrices are mainly atomized by the vibration of an ultrasonic atomizing plate. However, the high-frequency friction between the atomizing plate and the limiting component that fixes it during vibration can easily lead to excessive temperature rise, significantly affecting the efficacy of the aerosol-generating matrices. Furthermore, excessive noise reduces the user experience. Summary of the Invention

[0004] Therefore, it is necessary to provide an atomizing component and atomizer that have low noise during ultrasonic atomization and can avoid excessive temperature rise that would affect the drug properties of the aerosol-generating matrix.

[0007] In the aforementioned atomization assembly, the ultrasonic atomizing plate is clamped and fixed between the first and second elastic fins. When the ultrasonic atomizing plate reciprocates along its own axis, it can vibrate and atomize the aerosol generating matrix, thus achieving ultrasonic atomization. Furthermore, both the first and second elastic fins have deformation space on their sides facing away from the ultrasonic atomizing plate. When the ultrasonic atomizing plate vibrates along its own axis to atomize the aerosol generating matrix, the deformation space behind the first elastic fin allows it to float back and forth with the ultrasonic atomizing plate, and the deformation space behind the second elastic fin allows it to float back and forth with the ultrasonic atomizing plate. The ultrasonic atomizing plate can vibrate adaptively. The first and second elastic fins provide cushioning for the ultrasonic atomizing plate through their own elastic deformation, reducing noise during vibration, lowering friction, reducing heat generation, and preventing the efficacy of the aerosol generating matrix from being destroyed.

[0017] In one embodiment, the first fixing part and the second fixing part are independent of each other or connected to each other.

[0018] In one embodiment, the hardness of the first elastic fin is less than the hardness of the first fixing part, and the hardness of the second elastic fin is less than the hardness of the second body.

[0019] In one embodiment, both the first fixing part and the second fixing part are made of PP material, and both the first elastic fin and the second elastic fin are made of TPE material.

[0020] In one embodiment, both the first fixing portion and the second fixing portion are annular, the first elastic fin is tangentially connected to the inner ring of the first fixing portion, and / or the second elastic fin is tangentially connected to the inner ring of the second fixing portion.

[0038] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0040] 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0042] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0043] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening 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 possible implementation.

[0044] As described in the background section, ultrasonic atomizers are prone to problems such as excessive noise and excessive heat generation due to vibration and friction. The inventors have discovered that the root cause of this problem is that when the ultrasonic atomizing plate is fixed by a silicone pad, the ultrasonic atomizing plate vibrates back and forth along its own axis, causing interference with the silicone pad and resulting in noise. Furthermore, the high friction between the ultrasonic atomizing plate and the silicone pad causes excessive heat generation.

[0045] To address the aforementioned technical problems, this invention provides an atomizer that has low noise and generates less heat, does not affect the medicinal properties of the aerosol-generating matrix, and ensures a good user experience.

[0046] See Figure 1 In one embodiment of the present invention, an atomizer 100 is provided, including an atomizing body 12, a nozzle 32, and an atomizing component 10. The atomizing body 12 has a receiving cavity 121 for receiving an aerosol generating matrix, such as a liquid medicine. Furthermore, the atomizing body 12 has a liquid outlet 123 communicating with the receiving cavity 121. The nozzle 32 is mounted on the atomizing body 12 corresponding to the liquid outlet 123. The atomizing component 10 is disposed between the atomizing body 12 and the nozzle 32, and is used to atomize the aerosol generating matrix flowing out of the liquid outlet 123 into an aerosol. The atomized aerosol is sprayed out from the nozzle 32 for user use.

[0047] The atomizing assembly 10 includes a support body 30, an ultrasonic atomizing plate 50, a first elastic fin 14, and a second elastic fin 34. The support body 30 is fixed to at least one of the atomizing body 12 and the nozzle 32, and supports and connects the first elastic fin 14 and the second elastic fin 34. The first elastic fin 14 and the second elastic fin 34 are arranged facing each other and clamp the ultrasonic atomizing plate 50, and the ultrasonic atomizing plate 50 covers the liquid outlet 123. That is, the ultrasonic atomizing plate 50 is clamped and fixed between the first elastic fin 14 and the second elastic fin 34. When the ultrasonic atomizing plate 50 vibrates back and forth along its own axis, it vibrates and atomizes the aerosol matrix generated from the liquid outlet 123 into an aerosol flowing towards the nozzle 32, thereby realizing ultrasonic atomization.

[0048] Furthermore, both the first elastic fin 14 and the second elastic fin 34 have deformation spaces 20 on the side facing away from the ultrasonic atomizing plate 50. When the ultrasonic atomizing plate 50 vibrates along its own axis to atomize the aerosol and generate the matrix, the deformation space 20 behind the first elastic fin 14 allows the first elastic fin 14 to float back and forth with the ultrasonic atomizing plate 50, and the deformation space 20 behind the second elastic fin 34 allows the second elastic fin 34 to float back and forth with the ultrasonic atomizing plate 50. The ultrasonic atomizing plate 50 can vibrate adaptively. The first elastic fin 14 and the second elastic fin 34 provide buffer for the ultrasonic atomizing plate 50 through their own elastic deformation, reducing the noise when the ultrasonic atomizing plate 50 vibrates, reducing the friction force when the ultrasonic atomizing plate 50 vibrates, reducing the heat generated by the ultrasonic atomizing plate 50, and preventing the efficacy of the aerosol generating matrix from being destroyed.

[0049] See Figures 2-3 In some embodiments, both the first elastic fin 14 and the second elastic fin 34 include an elastic support portion 42 and an elastic abutment portion 44 connected to each other. One end of the elastic support portion 42 is connected to the atomizing body 12 or the nozzle 32, and the other end of the elastic support portion 42 is provided with the elastic abutment portion 44. The elastic abutment portion 44 abuts against the ultrasonic atomizing sheet 50, and the elastic abutment portion 44 and the elastic support portion 42 enclose a deformation space 20. In this way, the elastic support portion 42 supports the elastic abutment portion 44, so that the elastic abutment portion 44 abuts against the ultrasonic atomizing sheet 50. On the one hand, the elastic abutment portion 44 fixes the ultrasonic atomizing sheet 50, and on the other hand, the abutment between the elastic abutment portion 44 and the ultrasonic atomizing sheet 50 seals the ultrasonic atomizing sheet 50 to prevent leakage. In addition, the elastic support part 42 supports the elastic abutment part 44, and the elastic support part 42 and the elastic abutment part 44 define and form a deformation space 20, which allows the elastic abutment part 44 to adapt to vibration through the deformation space 20 after clamping the ultrasonic atomizing sheet 50, effectively reducing noise and heat generation.

[0050] Furthermore, the elastic abutment portion 44 is arranged in a ring shape and has an annular abutment surface 45 that abuts against the ultrasonic atomizing sheet 50. This means that the annular elastic abutment portion 44 is arranged around the outer periphery of the liquid outlet 123, and the annular abutment surface is used to abut and seal the ultrasonic atomizing sheet 50 from various positions on the outer periphery of the liquid outlet 123, ensuring the sealing effect while providing effective support.

[0051] Specifically, the elastic support portion 42 is trumpet-shaped, and the elastic abutment portion 44 is tangentially connected to the large end of the trumpet of the elastic support portion 42. This is equivalent to the diameter of the elastic support portion 42 gradually increasing to be the same as the inner diameter of the elastic abutment portion, so that the elastic support portion 42 and the elastic abutment portion 44 are gradually connected. The elastic support portion 42 can smoothly bear and transform the vibration impact received by the elastic abutment portion 44.

[0052] See Figures 4-5Optionally, the first elastic fin 14 has a plurality of slits 46, which are evenly spaced along the circumference of the first elastic fin 14 to improve the deformation capacity of the first elastic fin 14. Furthermore, the extension direction of each slit 46 intersects the radial direction of the first elastic fin 14. This arrangement of slits 46 that are radially inclined relative to the first elastic fin 14 ensures that when the first elastic fin 14 comes into contact with the ultrasonic atomizing plate 50, the slits 46 are filled by the deformed first elastic fin 14 itself, preventing the oblique slits 46 from expanding and effectively preventing leakage.

[0053] Alternatively, the second elastic fin 34 may have a plurality of slits 46, which are evenly spaced along the circumference of the second elastic fin 34 to improve its deformation capability. Furthermore, the extension direction of each slit 46 intersects the radial direction of the second elastic fin 34. This arrangement of slits 46, which are radially inclined relative to the second elastic fin 34, ensures that when the second elastic fin 34 comes into contact with the ultrasonic atomizing plate 50, the slits 46 are filled by the deformed second elastic fin 34 itself, preventing the oblique slits 46 from expanding and effectively preventing leakage.

[0054] See Figures 6-7 In some embodiments, the first elastic fin 14 has a different thickness at different positions in its circumferential direction, so that the first elastic fin 14 forms different supporting forces in its circumferential direction, thereby adaptively adjusting the elastic supporting force provided to the ultrasonic atomizing sheet 50, which can effectively clamp the ultrasonic atomizing sheet 50 and prevent liquid leakage. Optionally, the second elastic fin 34 has a different thickness at different positions in its circumferential direction, so that the second elastic fin 34 forms different supporting forces in its circumferential direction, thereby adaptively adjusting the elastic supporting force provided to the ultrasonic atomizing sheet 50, which can effectively clamp the ultrasonic atomizing sheet 50 and prevent liquid leakage.

[0055] In some embodiments, the support 30 includes a first fixing part 131 and a second fixing part 331, and a first elastic fin 14 and a second elastic fin 34 are respectively disposed on the first fixing part 131 and the second fixing part 331, so as to fix and support the first elastic fin 14 and the second elastic fin 34 respectively through the first fixing part 131 and the second fixing part 331.

[0056] In one specific embodiment, the first fixing part 131 and the second fixing part 331 are independent of each other. The first fixing part 131 can be assembled onto the atomizing body 12, thereby fixing the first elastic fin 14 onto the atomizing body 12. The second fixing part 331 can also be assembled onto the nozzle 32, thereby fixing the second elastic fin 34 onto the nozzle 32. In this way, the first elastic fin 14 and the second elastic fin 34 are respectively fixed onto the atomizing body 12 and the nozzle 32, thereby achieving the fixation of the first elastic fin 14 and the second elastic fin 34.

[0057] See Figures 1-3 In some embodiments, the atomizer 100 includes a first seal 13, which includes a first fixing portion 131 and a first elastic fin 14. The first fixing portion 131 is mounted on the atomizing body 12, and the first elastic fin 14 is disposed on the first fixing portion 131. The atomizer 100 also includes a second seal 33, which includes a second fixing portion 331 and a second elastic fin 34. The second fixing portion 331 is mounted on the nozzle 32, and the second elastic fin 34 is disposed on the second fixing portion 331.

[0058] Furthermore, the first fixing part 131 is interference-fitted with the atomizing body 12, and the second fixing part 331 is interference-fitted with the nozzle 32, thus effectively preventing leakage. Additionally, the first fixing part 131 is integrally formed with the first elastic fin 14, and the second fixing part 331 is integrally formed with the second elastic fin 34, so that the first elastic fin 14 and the second elastic fin 34 are respectively mounted and fixed by the first fixing part 131 and the second fixing part 331.

[0059] Specifically, the hardness of the first elastic fin 14 is less than the hardness of the first fixing part 131, and the hardness of the second elastic fin 34 is less than the hardness of the second fixing part 331. In this way, the first elastic fin 14 and the second elastic fin 34 can be supported by the first fixing part 131 and the second fixing part 331, which have higher hardness, respectively. The first fixing part 131 and the second fixing part 331 can withstand a large load. At the same time, the ultrasonic atomizing sheet 50 can be elastically clamped and fixed by the first elastic fin 14 and the second elastic fin 34, which have lower hardness, to ensure sufficient elastic deformation.

[0060] For example, both the first fixing part 131 and the second fixing part 331 are made of PP material, which has high hardness, while the first elastic fin 14 and the second elastic fin 34 are made of TPE material, which has good elasticity. In actual production, a hybrid injection molding process can be used to form the first sealing element 13 and the second sealing element 33.

[0061] See Figure 9In other embodiments, the first fixing part 131 and the second fixing part 331 are integrally formed with the atomizing body 12 and the nozzle 32, respectively. The first elastic fin 14 is disposed on the first fixing part 131 and the second elastic fin 34 is disposed on the second fixing part 331. This is equivalent to the first elastic fin 14, the first fixing part 131 and the atomizing body 12 being integrally formed, and the second elastic fin 34, the second fixing part 331 and the nozzle 32 being integrally formed. The first elastic fin 14 and the second elastic fin 34 are directly connected to the atomizing body 12 and the nozzle 32, respectively, and the ultrasonic atomizing plate 50 is clamped and fixed by the first elastic fin 14 and the second elastic fin 34.

[0062] Furthermore, the hardness of the first elastic fin 14 is less than that of the atomizing body 12, and the hardness of the second elastic fin 34 is less than that of the nozzle 32. The softer first elastic fin 14 and the second elastic fin 34 are placed on the harder atomizing body 12 and the nozzle 32, respectively. In this way, the first elastic fin 14 and the second elastic fin 34 can be supported by the harder atomizing body 12 and the nozzle 32, respectively. The atomizing body 12 and the nozzle 32 can withstand a large load. At the same time, the ultrasonic atomizing plate 50 can be elastically clamped and fixed by the softer first elastic fin 14 and the second elastic fin 34 to ensure sufficient elastic deformation.

[0063] For example, both the atomizing body 12 and the nozzle 32 are made of PP material, which has high hardness, while the first elastic fin 14 and the second elastic fin 34 are made of TPE material, which has good elasticity. In actual production, the atomizing body 12 and the first elastic fin 14 can be integrally molded using a mixed injection molding process, as can the nozzle 32 and the second elastic fin 34.

[0064] In another specific embodiment, the first fixing part 131 and the second fixing part 331 are connected to each other, and the support body 30 is a whole. The first fixing part 131 only needs to be fixed to the atomizing body 12. The second fixing part 331 can be not directly connected to the nozzle 32, or the second fixing part 331 can be fixed to the nozzle 32 and not directly connected to the atomizing body 12. In this way, the atomizing component 10 can also be placed between the nozzle 32 and the atomizing body 12. The method of fixing the atomizing component 10 is not limited here.

[0065] In any of the above embodiments, the first fixing part 131 is annular, and the first elastic fin 14 is tangentially connected to the inner ring of the first fixing part 131, so that the first elastic fin 14 and the first fixing part 131 are smoothly connected, preventing the first elastic fin 14 from breaking. The second fixing part 331 is annular, and the second elastic fin 34 is tangentially connected to the inner ring of the second fixing part 331, so that the second elastic fin 34 and the second fixing part 331 are smoothly connected, preventing the second elastic fin 34 from breaking. Optionally, the first elastic fin 14 is connected to the central ring of the first fixing part 131, and the second elastic fin 34 is connected to the central ring of the second fixing part 331. The placement of the first elastic fin 14 or the second elastic fin 34 is not limited here.

[0066] See Figure 8 In any of the above embodiments, the atomizing body 12 is provided with a plurality of limiting protrusions 125 around the liquid outlet 123. The plurality of limiting protrusions 125 define and form a positioning space 126 for accommodating the ultrasonic atomizing sheet 50, and the first elastic fin 14 is located within the positioning space 126. During the assembly process, the ultrasonic atomizing sheet 50 is first fitted into the positioning space 126 for initial positioning. Then, the nozzle 32 is assembled and fixed outside the atomizing body 12, so that the second elastic fin 34 on the nozzle 32 is opposite to the first elastic fin 14 in the positioning space 126 and clamps and fixes the ultrasonic atomizing sheet 50.

[0067] In one embodiment of the present invention, an atomizing component 10 according to any of the above embodiments is also provided. The atomizing component 10 includes a support body 30, an ultrasonic atomizing plate 50, a first elastic fin 14, and a second elastic fin 34. The support body 30 supports and connects the first elastic fin 14 and the second elastic fin 34. The first elastic fin 14 and the second elastic fin 34 are arranged facing each other and clamp the ultrasonic atomizing plate 50. That is, the ultrasonic atomizing plate 50 is clamped and fixed between the first elastic fin 14 and the second elastic fin 34. When the ultrasonic atomizing plate 50 vibrates back and forth along its own axis, it can generate an aerosol matrix that vibrates and atomizes the aerosol, thereby achieving ultrasonic atomization.

[0068] Furthermore, both the first elastic fin 14 and the second elastic fin 34 have deformation spaces 20 on the side facing away from the ultrasonic atomizing plate 50. When the ultrasonic atomizing plate 50 vibrates along its own axis to atomize the aerosol and generate the matrix, the deformation space 20 behind the first elastic fin 14 allows the first elastic fin 14 to float back and forth with the ultrasonic atomizing plate 50, and the deformation space 20 behind the second elastic fin 34 allows the second elastic fin 34 to float back and forth with the ultrasonic atomizing plate 50. The ultrasonic atomizing plate 50 can vibrate adaptively. The first elastic fin 14 and the second elastic fin 34 provide buffer for the ultrasonic atomizing plate 50 through their own elastic deformation, reducing the noise when the ultrasonic atomizing plate 50 vibrates, reducing the friction force when the ultrasonic atomizing plate 50 vibrates, reducing the heat generated by the ultrasonic atomizing plate 50, and preventing the efficacy of the aerosol generating matrix from being destroyed.

[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0070] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
