Abstract
Description
Technical Field
[0001] This application relates to the field of electronic atomization technology, and more specifically to an electronic atomization device and its power supply components. Background Technology
[0002] Electronic atomizing devices consist of an atomizing component and a power supply component that powers the atomizing component. When powered on, the atomizing component uses the thermal effect of an electronic heating element to heat the atomizing matrix, producing volatile substances such as aerosols. Traditional electronic atomizing devices have two symmetrical air inlets to regulate the internal air pressure balance, facilitating the smooth and uniform flow of the atomizing matrix to the electronic heating element for heating, and also helping the aerosol to be carried out of the device by the air. However, these two air inlets are easily blocked by dirt, which hinders airflow, affecting the uniform heating of the atomizing matrix and the taste of the generated aerosol. Furthermore, it disrupts the internal air pressure balance, causing leakage of the atomizing matrix and condensate. Utility Model Content
[0003] This application provides an electronic atomizing device and its power supply component, which can prevent the air inlet from being blocked, thereby improving the taste of the aerosol and preventing liquid leakage inside the electronic atomizing device.
[0004] This application provides an electronic atomizing device, comprising:
[0005] An atomizing component having an atomizing channel;
[0006] The system includes a power supply component connected to the atomizing component for supplying power to the atomizing component. The power supply component includes an outer sleeve and a housing. The outer sleeve is fitted over at least a portion of the structure of the housing. The outer sleeve has a first air inlet, and the housing has a second air inlet. An airflow space is provided between the outer sleeve and the housing. The first air inlet and the second air inlet are staggered and communicate with the second air inlet through the airflow space. The second air inlet communicates with the atomizing channel.
[0007] In some optional embodiments, the housing includes a fixing part and an airflow part, the fixing part being sealed to one end of the outer sleeve near the atomizing component, the airflow part being provided with a second air inlet, and the outer wall of the airflow part being spaced apart from the inner wall of the outer sleeve to form the airflow space.
[0008] In some alternative embodiments, the fixing part and the outer sleeve are riveted together at one end near the atomizing component.
[0009] In some optional embodiments, the inner wall of the outer sleeve is provided with a first groove, the bottom wall of the first groove being spaced apart from the outer wall of the housing to form the airflow space; and / or, the outer wall of the airflow section is provided with a second groove, the bottom wall of the second groove being spaced apart from the inner wall of the outer sleeve to form the airflow space.
[0010] In some alternative embodiments, the wall thickness of the airflow section near the fixed portion is greater than the wall thickness away from the fixed portion.
[0011] In some alternative embodiments, the wall thickness of the airflow section gradually decreases along the direction away from the fixing section.
[0012] In some alternative embodiments, the housing further includes a snap-fit portion extending outward along the outer wall of the airflow portion to form a stepped surface between the airflow portion and the snap-fit portion, with one end of the outer sleeve away from the atomizing component abutting against the stepped surface.
[0013] In some optional embodiments, the first air inlet has at least 6 holes and the second air inlet has at least 2 holes; the number of the second air inlet is less than the number of the first air inlet.
[0014] In some optional embodiments, at least six first air inlets are evenly arranged around the circumference of the outer sleeve, and at least two second air inlets are evenly arranged around the circumference of the housing; the axes of the at least six first air inlets and the at least two second air inlets are straight lines in the radial direction of the housing or the outer sleeve.
[0015] This application provides a power supply component, including an outer sleeve and a housing. The outer sleeve has a first air inlet, and the housing has a second air inlet. The outer sleeve is fitted over the outside of the housing, and an airflow space is provided between the outer sleeve and the housing. The first air inlet and the second air inlet are staggered and communicate with the second air inlet through the airflow space. The second air inlet is connected to an atomization channel.
[0016] According to the electronic atomizing device and power supply component in this embodiment, the power supply component includes an outer sleeve and a housing. The outer sleeve is fitted over the housing and has multiple first air inlets. The housing has a second air inlet. An airflow space is provided between the outer sleeve and the housing. The first and second air inlets are staggered and communicate with the second air inlet through the airflow space. Because the first and second air inlets are staggered, the entire air intake structure is prevented from being blocked, thus ensuring smooth air intake, improving the taste of the aerosol and the user experience. It also prevents internal pressure imbalance of the electronic atomizing device due to blockage of the air intake structure, which could lead to leakage of liquids such as atomizing matrix or condensate.

[0025] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.
[0026] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).
[0027] Aerosols are dispersions of solid or liquid particles in a gas. As used in this article, "aerosol" can generally refer to substances that have been vaporized, atomized, sprayed, or jetted, or otherwise transformed from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.
[0028] As used herein, the term "atomizing matrix" refers to any suitable compound or mixture of compounds that facilitates the formation of an aerosol (e.g., a stable aerosol that is substantially resistant to thermal degradation at the system's operating temperature) during use. Suitable atomizing matrices are well known in the art and include, but are not limited to: polyols such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as mono, di, or triacetic acid esters of glycerol; and aliphatic esters of mono, di, or polycarboxylic acids such as dimethyl dodecanoate and dimethyl tetradecanoate. Atomizing matrices may include nicotine. Atomizing matrices may include water. Atomizing matrices may include glycerol (also known as glycerol) having a higher boiling point than nicotine. Atomizing matrices may include propylene glycol. Atomizing matrices may include plant-based materials. Atomizing matrices may include homogeneous plant substrates. Homogeneous plant substrates may contain volatile compounds. These compounds may be released from the atomizing matrix upon heating. Atomizing matrices are generally provided in a liquid form, either directly within the container or via a storage medium (such as storage cotton or porous ceramic).
[0029] This application provides an electronic atomizing device capable of heating the aforementioned atomizing matrix to generate a stable aerosol in an atomized state, as described above.
[0030] Please see Figures 1 to 6 The atomizing device includes an atomizing component 100 and a power supply component 200. The atomizing component 100 is the main structure in the atomizing device that generates aerosols. The power supply component 200 provides the power required for the atomizing component 100 to operate. The power supply component 200 includes a battery (not shown in the figure) and a control circuit board (not shown in the figure). Specifically, the battery and the control circuit board are electrically connected to each other. The battery is used to supply power, and the control circuit board can control the operating state of the atomizing component 100, such as controlling different heating temperatures to change the aerosol generation rate and amount.
[0031] The atomizing component 100 has an atomizing channel 110. The atomizing component 100 also includes an atomizing chamber 120 and an atomizing matrix disposed in the atomizing chamber 120. The atomizing channel 110 is also disposed in the atomizing chamber 120. A heating element 130 is also disposed in the atomizing channel 110. When the electronic atomizing device is working, the atomizing matrix flows into the heating element 130 and is heated and atomized into an aerosol. The power supply component has an air intake structure. One end of the atomizing channel 110 is connected to the air intake structure, and the other end is connected to the outside of the electronic atomizing device. When the user inhales, air enters the interior of the electronic atomizing device along the air intake structure and then passes through the atomizing channel 110. This can regulate the air pressure balance inside the atomizing component 100 and can also carry the aerosol out of the electronic atomizing device for the user to inhale.
[0032] In some embodiments, the heating element 130 generates heat directly after being energized or generates heat based on electromagnetic effects in a magnetic field. The heating element 130 includes a heating cylinder or heating mesh made of resistive heating material, or an electromagnetic heating element, or includes a heat conductor and a heating film, heating layer, or heating circuit disposed on the heat conductor.
[0033] In some embodiments, the atomizing matrix can be directly placed in the cavity within the atomizing chamber 120, or placed in the atomizing chamber 120 using an intermediate medium made of porous ceramics, porous fibers, etc. A liquid inlet channel (not shown in the figure) is provided between the cavity containing the atomizing matrix and the atomizing channel 110 to facilitate the atomizing matrix flowing from the cavity into the heating element 130.
[0034] In some embodiments, the power supply component and the atomizing component 100 are detachably connected. Specifically, the power supply component and the atomizing component 100 are detachably connected by means of plug-in connection, threaded connection, or magnetic connection, so as to facilitate independent replacement and maintenance of the power supply component or the atomizing component 100, thereby extending the service life of the electronic atomizing device. Of course, in other embodiments, the power supply component and the atomizing component 100 may also be an integrally molded structure to constitute a disposable electronic atomizing device.
[0035] Please see Figures 2 to 6In some embodiments, the power supply assembly includes an outer sleeve 210 and a housing 220. The outer sleeve 210 is fitted over at least a portion of the structure of the housing 220. The outer sleeve 210 has a first air inlet 211, and the housing 220 has a second air inlet 2221. An airflow space 230 is provided between the outer sleeve 210 and the housing 220. The first air inlet 211 and the second air inlet 2221 are staggered and communicate with the second air inlet 2221 through the airflow space 230. The second air inlet 2221 communicates with the atomization channel 110. The first air inlet 211, the airflow space 230, and the second air inlet 2221 constitute the air intake structure within the power supply assembly. Airflow enters the airflow space 230 through the first air inlet 211 and then enters the atomization channel 110 through the second air inlet 2221. The airflow flows as follows: Figure 3 As shown, the airflow space 230 can also serve as an air buffer space, allowing air to continuously enter the atomization channel 110 through the second air inlet 2221. The first air inlet 211 and the second air inlet 2221 are staggered to prevent the entire air intake structure from being blocked, thus ensuring smooth air intake, improving the taste of the aerosol and the user experience, and also preventing the internal air pressure imbalance of the electronic atomization device caused by the blockage of the air intake structure, which could lead to leakage of liquids such as atomizing matrix or condensate.
[0036] The first air inlet 211 and the second air inlet 2221 are staggered, that is, the orthographic projection of the first air inlet 211 on the radial side of the outer sleeve 210 does not coincide with the orthographic projection of the second air inlet 2221 on the radial side of the outer sleeve 210.
[0037] The outer sleeve 210 is fitted onto the outside of at least a portion of the structure of the housing 220. This can be understood as the extension length of the outer sleeve 210 being less than that of the housing 220. The outer sleeve 210 can only be set on a portion of the structure of the housing 220. Alternatively, it can be understood as the outer sleeve 210 being completely fitted onto the outside of the housing 220.
[0038] In some embodiments, the atomizing component 100 is inserted into the housing 220, the battery and the control circuit board are disposed in the housing 220, and the control circuit board is electrically connected to the atomizing component 100 through the electrode post 240 to realize the power supply and control of the atomizing component 100.
[0039] Please see Figure 4 In some embodiments, the housing 220 includes a fixing part 221 and an airflow part 222. The fixing part 221 is sealed to one end of the outer sleeve 210 near the atomizing component 100. The airflow part 222 is provided with a second air inlet 2221, and the airflow part 222 is spaced apart from the interior of the outer sleeve 210 to form an airflow space 230.
[0040] In some embodiments, the fixing part 221 and the outer sleeve 210 are riveted together at the ends near the atomizing assembly 100. Of course, in other embodiments, the fixing part 221 and the outer sleeve 210 can also be glued or welded together to form a sealing structure. The assembly direction of the housing 220 and the outer sleeve 210 is as follows: Figure 4 As indicated by the middle arrow.
[0041] In some embodiments, the wall thickness of the airflow section 222 near the fixed part 221 is greater than the wall thickness of the end away from the fixed part 221, the wall thickness of the outer sleeve 210 remains unchanged, the end of the outer sleeve 210 near the atomizing assembly 100 is sealed to the fixed part 221, the end of the airflow section 222 is connected to the fixed part 221, and the wall thickness of the airflow section 222 near the fixed part 221 is greater than the wall thickness of the end away from the fixed part 221, so that there is a gap between the outer wall of at least a part of the structure of the airflow section 222 and the inner wall of the outer sleeve 210, the gap forming an airflow space 230 to connect the first air inlet 211 and the second air inlet 2221.
[0042] In some embodiments, the wall thickness of the airflow section 222 gradually decreases along the direction away from the fixing section 221.
[0043] Please see Figure 5 In some embodiments, a first groove 212 is provided on the inner wall of the outer sleeve 210 (the side facing the housing 220), the bottom wall of the first groove 212 (the wall in the extending direction of the outer sleeve 210) is spaced apart from the outer wall of the housing 220 to form an airflow space 230, and a first air inlet 211 is provided on the first groove 212.
[0044] Please see Figure 6 In some other embodiments, a second groove 2222 is provided on the outer wall of the airflow section 222. The bottom wall of the second groove 2222 (the wall in the extension direction of the housing 220) is spaced apart from the inner wall of the outer sleeve 210 to form an airflow space 230. The second air inlet 2221 is correspondingly provided at the second groove 2222.
[0045] Of course, in the above embodiments, the inner wall of the outer sleeve 210 may be provided with a first groove 212, and the outer wall of the airflow section 222 may be provided with a second groove 2222. The positions of the first groove 212 and the second groove 2222 are corresponding, and the first groove 212 and the second groove 2222 together enclose and form an airflow space 230.
[0046] In some embodiments, the housing 220 further includes a snap-fit portion 223, which extends outward along the outer wall of the airflow portion 222 to form a stepped surface 2231 between the airflow portion 222 and the snap-fit portion 223. One end of the outer sleeve 210 away from the atomizing component 100 abuts against the stepped surface 2231. The snap-fit portion 223 can limit the assembly position of the outer sleeve 210 and fix the outer sleeve 210.
[0047] In some embodiments, the end of the outer sleeve 210 away from the atomizing component 100 can be fixed to the stepped surface 2231 by means of bonding, riveting, or other methods.
[0048] In some embodiments, multiple first air inlets 211 and multiple second air inlets 2221 are provided, and the number of second air inlets 2221 is less than the number of first air inlets 211. Since the first air inlets 211 are located relatively outside the second air inlets 2221, they have more contact with external dust and other contaminants, making them prone to clogging. Providing multiple first air inlets 211 can reduce the probability of airflow blockage and poor airflow. The fact that the number of second air inlets 2221 is less than the number of first air inlets 211 allows for adjustment of the airflow entering the atomizing assembly 100.
[0049] In some embodiments, the first air inlet 211 has at least 6 holes and the second air inlet 2221 has at least 2 holes.
[0050] In some embodiments, the outer sleeve 210 and the housing 220 are hollow cylinders with matching shapes and sizes, and at least six first air inlets 211 are evenly arranged around the circumference of the outer sleeve 210, and at least two second air inlets 2221 are evenly arranged around the circumference of the housing 220.
[0051] In some embodiments, the axes of the first air inlet 211 and the second air inlet 2221 are straight lines in the radial direction of the housing 220 or the outer sleeve 210, that is, the first air inlet 211 and the second air inlet 2221 are straight-through structures to ensure smooth airflow.
[0052] Another embodiment of this application also provides a power supply component, which is the power supply component described above. This power supply component has been described in detail above and will not be repeated here.
[0053] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
