Description

[Technical Field]

[0001] This application relates to the field of atomization technology, and in particular to a liquid storage component, an atomizer, and an electronic atomization device. [Background Technology]

[0002] Traditional tobacco products (e.g., cigarettes, cigars, etc.) produce tobacco smoke by burning tobacco during use. Existing technologies offer alternatives to these traditional tobacco products by releasing compounds through heating without combustion. An example of such a product is an atomizer, which typically comprises a reservoir component for storing an atomizable liquid matrix, and an atomizing component for atomizing that liquid matrix to produce inhalable vapor or aerosol. The liquid matrix may contain nicotine and / or flavorings and / or aerosol-generating substances (e.g., glycerin).

[0003] As an example of existing solutions, some atomizers have separate liquid storage components and atomizing components. During use, the user needs to connect the liquid storage components and atomizing components. After connection, the liquid matrix in the liquid storage components can flow to the atomizing components through the liquid guiding channel formed by the connection between the two.

[0004] A liquid storage assembly typically includes a liquid storage chamber for storing a liquid matrix and a sealing silicone sealant for sealing the liquid storage chamber. The sealing silicone sealant has a liquid guide hole for the liquid matrix to flow through. The liquid guide hole is part of the aforementioned liquid guide channel. During the process of the liquid matrix in the liquid storage assembly being transferred to the atomizing assembly, air bubbles formed in the atomizing assembly can easily adhere to the hole wall of the liquid guide hole, causing the bubbles to accumulate in the liquid guide channel. This can then hinder the smooth flow of the liquid matrix in the liquid storage assembly to the atomizing assembly, resulting in the atomizing element on the atomizing assembly burning dry due to insufficient liquid supply. [Utility Model Content]

[0005] This application provides a liquid storage component, an atomizer, and an electronic atomizing device to solve the problem that bubbles formed when the atomizing component replenishes air to the liquid storage component are easily stuck in the liquid guiding channel, thereby hindering the further flow of the liquid matrix in the liquid storage component to the atomizing component.

Detailed Implementation Methods

[0042] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" or "attached to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected to" another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "upper," "lower," "left," "right," "inner," "outer," and similar expressions used in this specification are for illustrative purposes only.

[0043] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0044] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0045] In the embodiments of this application, "installation" includes fixing or restricting a component or device to a specific position or place by means of welding, screwing, snapping, bonding, etc. The component or device may remain stationary in the specific position or place or may move within a limited range. After the component or device is fixed or restricted to the specific position or place, it may or may not be disassembled. This application does not impose any restrictions.

[0046] 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 one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0047] One embodiment of this application provides an atomizer 100, such as Figure 1 and Figure 2 As shown, the atomizer 100 includes a liquid storage assembly 10 and an atomizing assembly 20. The liquid storage assembly 10 defines a liquid storage chamber 11 for storing an atomizable liquid matrix. The atomizing assembly 20 is provided with an atomizing element for generating an aerosol from the liquid matrix. The atomizer 100 also includes an outlet 12 for the aerosol to escape from the atomizer 100. The outlet 12 is disposed on the liquid storage assembly 10 and communicates with the atomizing element, so that the user can inhale the aerosol when inhaling through the outlet 12.

[0048] The atomizing component 20 can be connected to the liquid storage component 10. After connection, a liquid guiding channel is formed between the atomizing component 20 and the liquid storage component 10. The liquid guiding channel connects the liquid storage chamber 12 and the atomizing element. The liquid matrix in the liquid storage chamber 12 can flow to the atomizing element through the liquid guiding channel for atomization.

[0049] The connection method can be either detachable or non-detachable. When the connection is detachable, after the liquid matrix stored in the liquid reservoir 11 is depleted, the user can remove the liquid reservoir 10 from the atomizing component 20 and replace it with a new liquid reservoir 10, thus allowing the atomizing component 20 to be reused. However, when the connection is non-detachable, after the liquid matrix stored in the liquid reservoir 11 is depleted, the user needs to discard both the liquid reservoir 10 and the atomizing component 20, in which case the atomizing component 20 cannot be reused.

[0050] like Figure 2As shown, the atomizing assembly 20 includes a liquid storage component 21, and a liquid guiding channel communicates with the liquid storage component 21. The liquid matrix flowing from the liquid guiding channel enters and is stored in the liquid storage component 21. The liquid storage component 21 has a longitudinally penetrating through-hole (not shown). An atomizing tube 22 is disposed within the through-hole, and an atomizing element is disposed within the atomizing tube 22. The atomizing element includes a liquid guiding component 23 and a heating element 24 attached to the liquid guiding component 23. A notch (not shown) is formed in the wall of the atomizing tube 22, through which a portion of the liquid guiding component 23 extends and contacts the liquid storage component 21. The liquid storage component 21 can then transfer its stored liquid matrix to the liquid guiding component 23, which in turn transfers it to the heating element 24. The heating element 24 on the liquid guiding component 23 heats and atomizes the liquid matrix to generate an aerosol, which is then released into the atomizing tube 22.

[0051] like Figure 2 As shown, the liquid storage assembly 10 also includes a longitudinally extending air guide tube 13 in the liquid storage chamber 11. One end of the air guide tube 13 is connected to the air outlet 12, and the other end is connected to the atomizing tube 22, so that the aerosol released in the atomizing tube 22 can be further transferred to the air guide tube 13. When the user inhales at the air outlet 12, external air enters the atomizer 100 through the air inlet 25 of the atomizer, and then enters the atomizing tube 22, carrying the aerosol generated by the atomizing element in the atomizing tube 22 into the air guide tube 13. Finally, the air guide tube 13 transfers the aerosol to the air outlet 12 for the user to inhale. Figure 2 The airflow transmission path R1 of the atomizer 100 is shown.

[0052] Both the liquid storage component 21 and the liquid guiding component 23 can be made of porous materials, such as cotton fibers, non-woven fabrics, fiberglass ropes, porous glass, or porous ceramics. This allows the liquid storage component 21 and the liquid guiding component 23 to absorb or conduct the liquid matrix through their internal microporous structure or pores. Correspondingly, the heating element 24 can be attached to the liquid guiding component 23 or wound around it by means of printing, deposition, sintering, or physical assembly.

[0053] In other embodiments, the atomizing element may also be an ultrasonic atomizing element, such as an ultrasonic atomizing sheet. The ultrasonic atomizing element can generate ultrasonic waves and atomize the liquid matrix through ultrasonic waves. The atomizing element may also be other components that can make the liquid matrix form an aerosol. This application does not specifically limit the type of atomizing element.

[0054] like Figure 3As shown, the liquid storage assembly 10 also includes a sealing member 14 for sealing the liquid storage cavity 11 and a base 15 for supporting the sealing member 14. The sealing member 14 can be made of any of the flexible materials such as silicone, rubber or latex, so that the sealing member 14 can be elastically abutted between the inner wall of the liquid storage cavity 11 and the base 15, thereby providing a seal between the inner wall of the liquid storage cavity 11 and the base 15, preventing the liquid matrix in the liquid storage cavity 11 from leaking through the assembly gap between the inner wall of the liquid storage cavity 11 and the base 15.

[0055] The seal 14 and the base 15 are combined to form a liquid guiding assembly. The liquid guiding assembly has at least one liquid guiding hole to guide the liquid matrix out of the liquid storage chamber 11. So when the liquid storage assembly 10 and the atomizing assembly 20 are connected, the liquid matrix in the liquid storage assembly 10 can flow out of the liquid storage assembly 10 through the liquid guiding assembly and enter the atomizing assembly 20 for atomization.

[0056] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the liquid guiding hole includes a first liquid guiding hole 141 disposed on the sealing member 14 and communicating with the liquid storage chamber 11, and a second liquid guiding hole 151 disposed on the base 15. The first liquid guiding hole 141 and the second liquid guiding hole 151 are connected and are formed by... Figure 2 It is known that the first liquid guiding hole 141 is closer to the liquid storage chamber 11 than the second liquid guiding hole 151. In some embodiments, the base 15 is also provided with a liquid outlet for the liquid matrix to be output from the liquid storage assembly 10, and the second liquid guiding hole 151 is also connected to the liquid outlet, thereby enabling the second liquid guiding hole 151 to communicate with the outside. When the liquid storage assembly 10 is connected to the atomizing assembly 20, the liquid matrix in the liquid storage chamber 11 can flow to the atomizing assembly 20 through the first liquid guiding hole 141, the second liquid guiding hole 151 and the liquid outlet.

[0057] In some embodiments, such as Figure 3 As shown, the base 15 also includes at least one liquid guide column 153 extending away from the liquid storage cavity 11. The liquid guide column 153 is hollow, so that the hollow area of ​​the liquid guide column 153 can be used to define at least a portion of forming the second liquid guide hole 151. The side wall of the liquid guide column 153 is provided with a first liquid outlet 152a, which communicates with the second liquid guide hole 151. The opening direction of the first liquid outlet 152a is substantially perpendicular to the extension direction of the second liquid guide hole 151. That is, the first liquid outlet 152a connects the inner wall and the outer wall of the liquid guide column 151, so that the liquid matrix flowing into the liquid guide column 153 can flow out of the liquid storage assembly 10 from the first liquid outlet 152a.

[0058] The atomizing assembly 20 is provided with at least one insertion hole 26 for inserting a liquid guiding column 153. The insertion hole 26 communicates with the liquid storage component 21. Therefore, when the liquid storage assembly 10 is connected to the atomizing assembly 20, the liquid guiding column 153 is inserted into the insertion hole 26, and the liquid matrix in the liquid storage chamber 11 can flow to the liquid storage component 21 through the first liquid guiding hole 141, the liquid guiding column 153, and the liquid outlet 152. Figure 2 As shown in the liquid flow path R2, the above-mentioned liquid guiding channel is formed. In some embodiments, the positions of the insertion hole 26 and the liquid guiding column 153 can also be interchanged, that is, the liquid guiding column 153 is provided on the atomizing component 20, and the second liquid guiding hole 151 on the liquid storage component 10 can be used for the liquid guiding column 153 to be inserted.

[0059] like Figure 4 As shown, the cross-sectional area of ​​the first liquid guiding hole 141 is larger than that of the second liquid guiding hole 151, so that the liquid inlet 1511 of the second liquid guiding hole 151 is completely exposed in the first liquid guiding hole 141. This prevents air bubbles from adhering to the hole wall of the first liquid guiding hole 141 when the liquid storage assembly 10 and the atomizing assembly 20 are connected. This also prevents air bubbles from accumulating in the liquid guiding channel and blocking the liquid guiding channel, thus preventing the atomizing element in the atomizing assembly 20 from dry burning due to insufficient liquid supply.

[0060] In the prior art, the cross-sectional area and shape of the first liquid guiding hole 141 and the second liquid guiding hole 151 are exactly the same. This method can easily cause air bubbles to adhere to the hole wall of the first liquid guiding hole 141, thereby causing air bubbles to accumulate in the liquid guiding channel and block the liquid guiding channel.

[0061] It should be noted that the form of the liquid guiding component is not limited to this; in other embodiments, such as... Figure 7 As shown, a support 18 is provided in the housing of the liquid storage assembly 10. The support 18 and the housing together define a liquid storage cavity 11, meaning that part of the boundary of the liquid storage cavity 11 is defined by the support 18. A first liquid guide hole 141 is provided on the support 18. A base 15 is provided on the side of the support 18 away from the liquid storage cavity 11 to provide support for the support 18. At least a portion of the second liquid guide hole 151 is formed on the base 15. At this time, a sealing element 19 can be provided between the support 18 and the base 15 to seal the liquid storage cavity 11 and the assembly gap between the support 18 and the base 15.

[0062] In some embodiments, the base 15 can be driven to rotate relative to the support 18 in a first position and a second position. When the base 15 rotates relative to the support 18 to the first position, the first liquid guide hole 141 and the second liquid guide hole 151 are connected to each other; while when the base 18 rotates relative to the support 18 to the second position, the first liquid guide hole 141 and the second liquid guide hole 151 are staggered.

[0063] Before the liquid storage assembly 10 and the atomizing assembly 20 are connected, the user can rotate the base 18 relative to the bracket 18 to the second position, thereby causing the first liquid guide hole 141 and the second liquid guide hole 151 to be offset from each other to prevent the liquid matrix in the liquid storage chamber 11 from leaking. After the liquid storage assembly 10 and the atomizing assembly 20 are connected, the user can rotate the base 15 relative to the bracket 18 to the first position. At this time, the first liquid guide hole 141 and the second liquid guide hole 151 are connected to each other, so that the liquid matrix in the liquid storage chamber 11 flows out of the liquid storage assembly 10 and into the atomizing assembly 20.

[0064] In some embodiments, such as Figure 2 As shown, the liquid guiding assembly has multiple spaced first liquid guiding holes 141 on the side facing the liquid storage chamber 11, specifically in... Figure 2 In the illustrated embodiment, there are two first liquid guiding holes 141. In other embodiments, there may be three, four, or more first liquid guiding holes 141. The corresponding base 15 is also provided with two or more second liquid guiding holes 151. The multiple first liquid guiding holes 141 and second liquid guiding holes 151 are connected to each other, thereby establishing multiple liquid guiding channels R2 between the liquid storage component 10 and the atomizing component 20.

[0065] like Figure 5 and Figure 7 As shown, the multiple first liquid guiding holes 141 have different cross-sectional areas, so that when the liquid storage assembly 10 and the atomizing assembly 20 are connected, each liquid guiding channel has a different pressure. The pressure on the air bubbles formed in each liquid guiding channel is also different, which can prevent the bubbles from rising to the liquid storage chamber 11 simultaneously in each liquid guiding channel, thereby further alleviating the problem of bubble accumulation in the liquid guiding channels and causing blockage. The term "simultaneous rise" here means that the bubbles in each liquid guiding channel maintain the same height when they rise, that is, the bubbles in each liquid guiding channel rise at the same speed.

[0066] In some embodiments, if the cross-sectional shape of the plurality of first liquid guiding holes 141 is the same, for example, they are all circular, then the plurality of first liquid guiding holes 141 can have different cross-sectional areas by having different inner diameters. When the cross-sectional shape of the plurality of first liquid guiding holes 141 is not circular, the equivalent diameters of the plurality of first liquid guiding holes 141 can be different, thus making the plurality of first liquid guiding holes 141 have different cross-sectional areas.

[0067] Alternatively, in some embodiments, the multiple first liquid guiding holes 141 may have different cross-sectional shapes, such as one liquid guiding hole 141 being square and another liquid guiding hole 141 being circular, thus allowing the multiple first liquid guiding holes 141 to have different cross-sectional areas.

[0068] In some embodiments, such as Figure 2 and Figure 4 As shown, the cross-sectional shape or cross-sectional area of ​​the plurality of first liquid guiding holes 141 are identical, thereby facilitating processing. In some embodiments, such as Figure 4 As shown, the cross-section of the first liquid guiding hole 141 is non-circular to reduce the contact area between the air bubble and the hole wall of the first liquid guiding hole 141, thereby reducing the probability of the air bubble adhering to the hole wall of the first liquid guiding hole 141.

[0069] In some embodiments, such as Figure 4 As shown, the cross-sectional shape of the first liquid guiding hole 141 is arc-shaped. Alternatively, in some embodiments, the cross-sectional shape of the first liquid guiding hole 141 is rectangular.

[0070] In some embodiments, such as Figure 4 As shown, the inlet 1511 of the second liquid guiding hole 151 is located in the central region of the first liquid guiding hole 141, so as to further reduce the contact area between the air bubble and the hole wall of the first liquid guiding hole 141. In some embodiments, such as Figure 6 and Figure 7 As shown, the end face of the liquid guiding column 153 away from the liquid storage chamber 11 is provided with a plurality of grooves 1531, and a notch is opened on the end face to form a second liquid outlet 152b for outputting liquid matrix to the liquid storage assembly 10. At this time, it is not necessary to provide a first liquid outlet 152a on the side wall of the liquid guiding column 153. The opening direction of the second liquid outlet 152b is basically perpendicular to the second liquid guiding hole 151, so that the liquid matrix flowing into the liquid guiding column 153 can flow out of the liquid storage assembly 10 through the second liquid outlet 152b.

[0071] The groove 1531 extends radially from the second liquid outlet 152b along the end face of the liquid guide column 153. When the liquid guide column 153 is inserted into the insertion hole 26 of the atomizing component 20, the groove 1531 can define at least one air channel with the surface of the liquid storage component 21 in the atomizing component 20. This air channel is used to allow external air to enter the liquid storage chamber 11. When the user inhales, external air can enter the liquid storage chamber 11 through these air channels to maintain the air pressure balance in the liquid storage chamber 11 and prevent negative pressure from being generated in the liquid storage chamber 11, which would prevent the liquid in the liquid storage chamber 11 from continuing to flow to the atomizing element.

[0072] One embodiment of this application also provides an electronic atomizing device, which can be found in [reference needed]. Figure 8 As shown, it includes an atomizer 100 that stores a liquid matrix and atomizes it to generate an aerosol, and a power supply assembly 200 that supplies power to the atomizer 100.

[0073] In an alternative implementation, for example Figure 8As shown, the power supply assembly 200 includes a receiving cavity 210 disposed at one end along the length direction for receiving and accommodating at least a portion of the atomizer 100, and an electrical contact 220 at least partially exposed on the surface of the receiving cavity 210 for forming an electrical connection with the electrode 16 of the atomizer 100 to supply power to the atomizer 100 when at least a portion of the atomizer 100 is received and accommodated in the power supply assembly 200.

[0074] A sealing element 230 is provided inside the power supply assembly 200, and the sealing element 230 divides at least a portion of the internal space of the power supply assembly 200 to form the receiving cavity 210. Figure 8 In the preferred embodiment shown, the seal 230 is configured to extend along the cross-sectional direction of the power assembly 200, and is preferably made of a flexible material such as silicone, thereby preventing the liquid matrix that seeps from the atomizer 100 into the receiving cavity 210 from flowing into components such as the controller 240 and sensor 250 inside the power assembly 200.

[0075] exist Figure 8 In the preferred embodiment shown, the power supply assembly 200 further includes a battery cell 260 for power supply located at the other end of the receiving cavity 210 along its length; and a controller 240 disposed between the battery cell 260 and the receiving cavity 210, the controller 240 being operable to guide current between the battery cell 260 and the electrical contact 220.

[0076] In use, the power supply assembly 200 includes a sensor 250 for sensing the suction airflow generated when the user inhales through the air outlet 111 of the atomizer 100, and then the controller 240 controls the battery cell 260 to output current to the atomizer 100 according to the detection signal of the sensor 250.

[0077] Further in Figure 8 In the preferred embodiment shown, the power supply assembly 200 has a charging unit 270 at the other end away from the receiving cavity 210 for charging the battery cell 260.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them; under the concept of this application, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this application as described above, which are not provided in detail for the sake of brevity; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
