Abstract
Description
Technical Field
[0001] This utility model relates to the field of atomization technology, and in particular to an atomizer and atomization device. Background Technology
[0002] Electronic atomizing devices are used to atomize a substrate into an aerosol for user consumption. They are widely used in industries such as e-cigarettes, medical devices, and beauty products. Electronic atomizing devices primarily work by heating the substrate with an atomizing component to generate an aerosol. The aerosol then flows out of the mouthpiece for the user to inhale. During atomization, some of the aerosol condenses in the mouthpiece, forming condensate. When this condensate accumulates to a certain level, the user may inhale it, affecting the user experience and potentially posing a health risk. Utility Model Content

[0007] In some embodiments, the mouthpiece airway includes a first airway and a second airway that are connected to each other. The first airway is closer to the atomizing component than the second airway. The inner wall of the first airway is formed with the stepped structure. The lateral dimension of at least a portion of the second airway gradually decreases in the direction close to the atomizing component.
[0008] In some embodiments, the housing includes a housing body, a base, and a mouthpiece inner tube; the base is connected to the housing body, and the base and the housing body together enclose the cavity; the mouthpiece inner tube is connected to the housing body, and one end of the mouthpiece inner tube away from the housing body extends into the cavity, defining the mouthpiece air passage; the atomizing component is disposed between the base and the mouthpiece inner tube.
[0009] In some embodiments, the atomizer further includes a first sealing member, which is sealed to the inner tube of the mouthpiece and the atomizing assembly respectively.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.
[0026] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.
[0027] 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).
[0028] It should be noted that the directional terms "up," "down," and "horizontal" mentioned in the text can be found in the appendix. Figure 2 The X, Y, and Z markings indicate the direction. X represents horizontal, Y represents upward, and Z represents downward.
[0029] Please see Figure 1 In some embodiments, an atomizing device is provided, comprising an atomizer and a power supply unit (not shown) connected to the atomizer. The power supply unit and the atomizer may be mechanically and / or electrically connected; or they may be detachably connected. The power supply unit is capable of providing power to the atomizer and controlling its switching, power, etc., for heating and atomizing a stored atomizing matrix to generate an aerosol when energized.
[0030] like Figures 1 to 4 As shown, in some embodiments, the atomizer includes a housing 10 and an atomizing assembly 11. The housing 10 has a cavity in which the atomizing assembly 11 is disposed. The cavity includes a reservoir 12 for storing a liquid atomizing matrix, which surrounds the periphery of the atomizing assembly 11. The reservoir 12 is in communication with the atomizing assembly 11 and is capable of supplying the atomizing matrix to the atomizing assembly 11.
[0031] like Figures 2 to 6 As shown, in some embodiments, the housing 10 further forms a mouthpiece airway 13, which is connected to the atomizing assembly 11. The end of the mouthpiece airway 13 furthest from the atomizing assembly 11 (see reference) Figure 2The upper end of the mouthpiece airway 13 is connected to the atmosphere outside the housing 10. The aerosol generated at the atomizing component 11 flows through the mouthpiece airway 13 and overflows outside the housing 10. The aerosol is inhaled by the user at the end of the mouthpiece airway 13 furthest from the atomizing component 11. As the temperature decreases, condensate gradually accumulates in the mouthpiece airway 13, which easily flows into the user's mouth during the next inhalation. To solve this problem, a stepped structure 14 is formed on the inner wall of the mouthpiece airway 13, which increases the resistance to the upward movement of condensate. The stepped structure 14 includes at least two recesses 140. That is, the number of recesses 140 can be two, three, four, etc. Each recess 140 is recessed laterally away from the central axis 20 of the mouthpiece airway 13, and the lateral dimension of each recess 140 increases progressively towards the atomizing component 11. Specifically, as shown... Figure 5 and Figure 6 In the illustrated embodiment, the stepped structure 14 includes two recesses 140. One recess 140, located further away from the atomizing component 11 (the upper recess 140), has a lateral dimension of L1, while the other recess 140, located closer to the atomizing component 11 (the lower recess 140), has a lateral dimension of L2. L1 is smaller than L2. That is, the stepped structure 14 includes at least two steps. These at least two recesses 140 increase the length and curvature of the upward flow path of condensate within the mouthpiece airway 13. The stepped structure 14 laterally obstructs the upward flow path of the condensate, increasing the resistance to its upward movement and effectively reducing the risk of the user inhaling condensate.
[0032] To prevent condensate from being carried into the user's mouth, related technologies typically add additional components to the mouthpiece airway 13 to trap condensate. However, these additional components increase manufacturing costs and assembly steps, hindering mass production. This application only requires designing at least two steps within the mouthpiece airway 13, without adding any other components, and does not change the original assembly steps. The structure is simple, the modification cost is low, and it is conducive to mass production.
[0033] like Figure 7As shown, in some embodiments, the housing 10 is provided with a liquid injection hole 101, and the atomizer also includes a sealing member 15, which is detachably sealed to the liquid injection hole 101. That is, by removing the sealing member 15, the atomizing matrix can be replenished into the liquid storage chamber 12 through the liquid injection hole 101. Thus, when the amount of atomizing matrix in the liquid storage chamber 12 is insufficient, the atomizing matrix can be replenished conveniently and quickly, and the atomizer can be used continuously for a long time. Due to the continuous use of the atomizer for a long time, condensate will accumulate more easily in the mouthpiece air passage 13. Tests have shown that after the liquid storage chamber 12 has been replaced with atomizing matrix 15 to 20 times, a large amount of condensate will accumulate in the mouthpiece air passage 13. The stepped structure 14 formed by at least two recesses 140 in the mouthpiece air passage 13 can effectively increase the length and curvature of the upward flow path of the condensate in the mouthpiece air passage 13, increase the resistance to the upward movement of the condensate, and effectively reduce the risk of the user inhaling the condensate.
[0034] like Figures 2 to 4 As shown, in some embodiments, the atomizing assembly 11 includes an atomizing tube 110 and an atomizing core disposed within the cavity formed by the atomizing tube 110. The atomizing core includes a liquid guide 111 and a heating element 112. The atomizing tube 110 surrounds the liquid guide 111, which is cylindrical with both ends open. The heating element 112 is attached to the inner circumferential surface of the liquid guide 111. The atomizing tube 110 has a liquid inlet hole 1101, through which the liquid guide 111 communicates with the liquid storage cavity 12, thereby providing the atomizing matrix for the heating element 112. When the atomizer and the power supply unit are connected together, an electrical connection is formed between the heating element 112 and the power supply unit. The heating element 112 heats up when energized, heating and atomizing the atomizing matrix to form an aerosol. The aerosol and air flow out through the mouthpiece air passage 13 for the user to inhale.
[0035] like Figure 5 and Figure 6 In the illustrated embodiment, each recess 140 includes a first surface 1401 and a second surface 1402, with the first surface 1401 facing the atomizing assembly 11. The second surface 1402 and the first surface 1401 are joined at an angle. That is, the second surface 1402 and the first surface 1401 are not parallel. The first surface 1401 facing the atomizing assembly 11 can prevent condensate from flowing upward. Specifically, as... Figure 5 As shown, in some embodiments, the first surface 1401 is perpendicular to the central axis 20 of the mouthpiece airway 13, that is, a 90° angle is formed between the first surface 1401 and the central axis 20 of the mouthpiece airway 13; or, as... Figure 6 As shown, in some other embodiments, a non-90° angle is formed between the first surface 1401 and the central axis 20 of the suction airway 13. Further, as... Figure 5 and Figure 6As shown, the second surface 1402 can be parallel to the central axis 20 of the mouthpiece airway 13. As a result, the condensate flows downward at the second surface 1402 due to its own weight, and some of the condensate can also flow back to the atomizing component 11.
[0036] like Figures 2 to 6 As shown, in some embodiments, the mouthpiece airway 13 includes a first airway 131 and a second airway 132 that are connected to each other. The first airway 131 is closer to the atomizing assembly 11 than the second airway 132. (Reference) Figure 5 As shown, the first air passage 131 is located further downwards than the second air passage 132. The inner wall of the first air passage 131 has a stepped structure 14. The lateral dimension of at least a portion of the second air passage 132 gradually decreases towards the atomizing component 11. That is, as... Figure 5 As shown, the second airway 132 can have a portion of its lateral dimension near the first airway 131 that gradually decreases in the direction of approaching the atomizing component 11 (downwards), while the lateral dimension of another portion of the second airway 132 away from the first airway 131 (i.e., the area near the mouthpiece) is uniform. Alternatively, the entire second airway 132 can have its lateral dimension gradually decreasing in the direction of approaching the atomizing component 11 (downwards). The portion of the second airway 132 where the lateral dimension gradually decreases in the direction of approaching the atomizing component 11 serves to guide the condensate downwards. Condensate adhering to the second airway 132 is guided downwards, thereby reducing condensate accumulation within the second airway 132.
[0037] like Figures 2 to 6 As shown, in some embodiments, each recess 140 of the stepped structure 14 is annular. That is, each recess 140 surrounds the central axis 20 of the mouthpiece air passage 13, and such a structure is easy to process and manufacture. Alternatively, in other embodiments, the circumferential dimension of each recess 140 along the mouthpiece air passage 13 may be smaller than the circumference of the mouthpiece air passage 13. For example, each recess 140 may also be a strip-shaped groove extending along the central axis 20 of the mouthpiece air passage 13.
[0038] like Figures 2 to 4 As shown, in some embodiments, the housing 10 includes a housing body 102, a base 103, and a mouthpiece inner tube 104. The base 103 is connected to the housing body 102, and the base 103 and the housing body 102 together enclose a cavity. The atomizing assembly 11 is disposed between the base 103 and the mouthpiece inner tube 104. The mouthpiece inner tube 104 is connected to the housing body 102, and one end of the mouthpiece inner tube 104 away from the housing body 102 extends into the cavity, defining a mouthpiece airway 13. Figure 2As shown, the upper surface of the base 103, the inner surface of the shell body 102, the outer peripheral surface of the nozzle inner tube 104, and the outer peripheral surface of the atomizing tube 110 of the atomizing assembly 11 together define the liquid storage chamber 12. The nozzle inner tube 104 and the shell body 102 can be integrally formed. The base 103 and the shell body 102 can be detachably connected to facilitate the installation of the atomizing assembly 11.
[0039] like Figures 2 to 4 As shown, in some embodiments, the atomizer further includes a first sealing member 16, which is sealed to the mouthpiece inner tube 104 and the atomizing assembly 11. That is, the upper and lower ends of the first sealing member 16 are connected to the mouthpiece inner tube 104 and the atomizing tube 110 of the atomizing assembly 11, respectively. The first sealing member 16 is provided with a central through hole 160, which is connected to the mouthpiece air passage 13 and the liquid guide 111 of the atomizing assembly 11, so that the aerosol generated near the liquid guide 111 can flow sequentially through the central through hole 160 on the first sealing member 16 and the mouthpiece air passage 13.
[0040] In some embodiments, the lateral dimension of at least a portion of the inner wall surface of the central through-hole 160 gradually decreases along the direction approaching the atomizing assembly 11. For example... Figure 2 and Figure 4 In the illustrated embodiment, the central through-hole 160 has a gradient region near the nozzle air passage 13. The lateral dimension of this gradient region gradually decreases along the direction approaching the atomizing component 11, forming a guide slope that guides the condensate to flow downwards. Alternatively, in some other embodiments, the inner wall surface of the central through-hole 160 may also have a lateral dimension that gradually decreases along the direction approaching the atomizing component 11 throughout, meaning that the central through-hole 160 is generally an inverted cone shape.
[0041] like Figure 2 and Figure 7 As shown, in some embodiments, the base 103 is provided with a liquid storage tank 1030, which is connected to the atomizing component 11. Specifically, the liquid storage tank 1030 is connected to the liquid guide 111. Thus, the nozzle air passage 13, the liquid guide 111 of the atomizing component 11, and the liquid storage tank 1030 are sequentially connected. The liquid storage tank 1030 can be used to store condensate or atomized matrix that is not completely atomized at the atomizing core, preventing liquid leakage to other locations and contaminating electronic components.
[0042] like Figures 2 to 4 , Figure 7 and Figure 8As shown, in some embodiments, the base 103 includes a bottom cover 1031 and a liquid-absorbing member 1033. The bottom cover 1031 is connected to the shell body 102. The liquid-absorbing member 1033 is disposed on the surface of the bottom cover 1031 facing the atomizing assembly 11, and the surface portion of the liquid-absorbing member 1033 facing the atomizing assembly 11 is recessed to form a liquid storage groove 1030. The liquid-absorbing member 1033 can be a porous structure such as absorbent cotton, which has the characteristic of absorbing liquid. Further, the base 103 also includes a mounting base 1034 and a second sealing member 1032. The second sealing member 1032 is located on the side of the bottom cover 1031 facing the atomizing assembly 11, and the second sealing member 1032 is sealed to the shell body 102. The mounting base 1034 is disposed between the second sealing member 1032 and the bottom cover 1031. The second sealing element 1032 has a recessed mounting groove 17 on its surface facing away from the mounting base 1034. The end of the atomizing tube 110 away from the nozzle air passage 13 is fitted into the mounting groove 17. The surface of the second sealing element 1032 facing away from the mounting base 1034, the inner surface of the housing body 102, the outer peripheral surface of the nozzle inner tube 104, the first sealing element 16, and the outer peripheral surface of the atomizing tube 110 together define the liquid storage chamber 12. Due to the presence of the first sealing element 16 and the second sealing element 1032, the liquid storage chamber 12 has good airtightness.
[0043] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
