Description

[Technical Field]

[0001] This application relates to the field of atomization technology, and more particularly to a power supply component for an electronic atomization device and an electronic atomization device including the power supply component. [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. Examples of such products are electronic atomizing devices, which typically include a power supply component to provide electrical energy to the atomizer. The atomizer stores and atomizes a liquid matrix to produce inhalable vapor or aerosol. This liquid matrix may contain nicotine and / or flavorings and / or aerosol-generating substances (e.g., glycerin).

[0003] Power supply components typically have a housing chamber for housing the atomizer. The atomizer is removably housed in the housing chamber, making it easy to replace the atomizer when the liquid matrix in the atomizer is depleted. The air inlet of existing electronic atomizing devices is usually located at the bottom of the power supply component. When the user inhales, outside air enters the power supply component through the air inlet, passes through the power supply component, and then enters the atomizer, thereby carrying away the aerosol produced by the atomizer after atomization.

[0004] Placing the air intake at the bottom of the power supply unit requires an air intake channel within the unit, which occupies considerable space and encroaches on the mounting space for electronic components. Furthermore, since the air intake channel passes through the power supply unit's structure, aerosols generated by the atomizer can easily flow back into the air intake channel, forming condensate and potentially damaging electronic components. [Utility Model Content]

[0005] This application provides an electronic atomizing device and a power supply assembly to solve the technical problems in the prior art where the air intake channel occupies a lot of space in the power supply assembly, and the aerosol generated by the atomizer easily flows back into the air intake channel, thereby forming condensate in the air intake channel and damaging the electronic components in the power supply assembly.

[0007] At least one atomizer is provided with a reservoir for storing a liquid matrix and an atomizing component for atomizing the liquid matrix to generate an aerosol.

The power supply assembly also includes a first sealing member supported by the bracket, and the first sealing member and the bracket defining a sealed chamber through which airflow passes.

[0010] The first seal has a first air inlet and a first air outlet. The first air inlet connects the first receiving chamber and the sealed chamber to guide external air flowing into the first receiving chamber to the sealed chamber. The first air outlet connects to the sealed chamber. The atomizer has a second air inlet that connects to the atomizing assembly. When the atomizer is housed in the first receiving chamber, the first air outlet connects to the second air inlet to guide external air from the sealed chamber into the atomizer.

[0011] In one embodiment, the electronic atomizing device further includes a mouthpiece connected to the power supply assembly, the mouthpiece defining a second receiving chamber, wherein when the mouthpiece is connected to the power supply assembly, the first receiving chamber and the second receiving chamber communicate to form a receiving chamber for accommodating the atomizer.

[0012] In one embodiment, when the mouthpiece is connected to the power assembly, the mouthpiece provides pressure to the atomizer, thereby holding the atomizer in the second receiving chamber.

[0013] In one embodiment, the mouthpiece is provided with a third air inlet for external air to enter the electronic atomizing device; or, the mouthpiece and the housing define a third air inlet for external air to enter the electronic atomizing device.

[0014] In one embodiment, a gap is maintained between the atomizer and the inner wall of the housing, the gap connecting the third air inlet and the first air inlet.

[0015] In one embodiment, the electronic atomizing device has a first end and a second end disposed opposite to each other along its length, and a first outer surface and a second outer surface extending between the first end and the second end, the surface area of ​​the first outer surface being greater than the surface area of ​​the second outer surface, and the third air inlet being disposed on the first outer surface.

[0016] In one embodiment, the atomizer includes a plurality of atomizers, which are held side by side in the second receiving chamber. The number of first air outlets is the same as the number of atomizers, and one first air outlet corresponds to one second air inlet.

[0017] In one embodiment, the first seal has a first surface facing the first receiving chamber, and a partition extends from the first surface toward the first receiving chamber, the partition being used to separate the plurality of atomizers from each other.

[0018] In one embodiment, the partition wall includes adjacent first and second inclined surfaces that extend from the first surface toward the first receiving chamber and are close to each other.

[0019] In one embodiment, the power assembly further includes an electrical contact for electrically connecting to the electrodes of the atomizer, and the support further includes a first protrusion passing through the sealed chamber and exposed in the first receiving chamber, the first protrusion being hollow to allow the electrical contact to pass through, and the outer surface of the first protrusion having an abutment protrusion for abutting against the first seal.

[0020] In one embodiment, the first seal has a second surface facing the sealing chamber, and a clamping portion extending from the second surface toward the sealing chamber, the clamping portion having a clamping space, and the bracket further includes a second protrusion extending into the sealing chamber, the protrusion being clamped in the clamping space.

[0021] At least one embodiment of this application also provides a power supply component, including:

[0022] shell;

[0023] The bracket is disposed within the housing;

[0024] The outer casing and the support define a first receiving chamber for accommodating at least a portion of the atomizer. The power assembly further includes a first sealing member supported by the support, and a sealed chamber for airflow is defined between the first sealing member and the support.

[0025] The first seal has a first air inlet and a first air outlet, both of which are connected to the first receiving chamber and the sealed chamber.

[0026] The electronic atomizing device provided in the above embodiments includes a power supply component comprising a housing and a support. The housing and support define a first receiving chamber for housing an atomizer. A first sealing element is supported on the support, and the first sealing element and the support define a sealed chamber. The first sealing element has a first air inlet and a first air outlet, both of which communicate with the sealed chamber and the first receiving chamber. The first air inlet guides external air into the sealed chamber, while the first air outlet guides air from the sealed chamber into the atomizer. In this way, external air can enter the power supply component through the first air inlet and then flow out of the power supply component through the sealed chamber and the first air outlet. The air intake structure is simple, eliminating the need to place the air inlet for guiding external air at the bottom of the power supply component, thus saving space. Furthermore, it prevents aerosols generated by the atomizer from easily flowing back into the air intake channel, further forming condensate within the air intake channel, thereby damaging electronic components.

[0037] 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.

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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] One embodiment of this application provides an electronic atomizing device 100, such as... Figure 1 and Figure 2As shown, the electronic atomizing device 100 includes a mouthpiece 10, at least one atomizer 20, and a power supply component 30. The atomizer 20 is provided with a liquid storage chamber for storing an atomizable liquid matrix, and an atomizing component for atomizing the liquid matrix from the liquid storage chamber to generate an aerosol. The power supply component 30 is used to provide the atomizer 20 with the electrical energy required for atomization. The mouthpiece 10 is provided with a second air outlet 11, which is used to allow the aerosol to escape from the electronic atomizing device 100. The user can inhale the aerosol by sucking through the second air outlet 11.

[0043] like Figure 2 and Figure 5 As shown, the power supply assembly 30 includes a first receiving chamber 31 for accommodating at least a portion of the atomizer 20. The power supply assembly 30 includes a housing 32 and a support 33 disposed within the housing 32. The support 33 and the inner wall of the housing 32 together define the first receiving chamber 31. The power supply assembly 30 also includes a battery cell 34 and a circuit board 35. The circuit board 35 may be the mainboard of the electronic atomizing device 100. The circuit board 35 is equipped with a controller for the electronic atomizing device and electrical contacts 351. When the atomizer 20 is accommodated in the first receiving chamber 31, the electrical contacts 351 maintain an electrical connection with the atomizer 20, thereby enabling the controller to control the battery cell 34 to provide the electrical energy required for atomization to the atomizer 20.

[0044] like Figure 4 As shown, the atomizer 20 is provided with a liquid storage chamber 211 for storing a liquid matrix and a liquid suction member 212. The liquid matrix stored in the liquid storage chamber 211 flows to the liquid suction member 212 through an internal liquid guide, thereby allowing the liquid suction member 212 to absorb and retain the liquid matrix. The atomizer 20 also includes a hollow tubular body 215 that extends through the liquid suction member 212. An atomizing assembly is disposed in the tubular body 215, which includes a liquid guide member 213 and a heating element 214 attached to the liquid guide member 213. The tube wall of the tubular body 215 is provided with a notch (not shown in the figure), so that a local area of ​​the liquid guiding member 213 can extend through the notch to contact the liquid suction member 212. The liquid matrix absorbed in the liquid suction member 212 can be transferred to the liquid guiding member 213. The liquid guiding member 213 further transfers the liquid matrix to the heating element 214. The heating element 214 heats and atomizes the liquid matrix to generate an aerosol, and releases the aerosol into the tubular body 212.

[0045] The atomizer 20 has a second air inlet 21 and a third air outlet 22 disposed opposite to each other. The second air inlet 21 allows outside air to enter the atomizer 20, while the third air outlet 22 allows the aerosol generated after atomization to escape from the atomizer 20. The third air outlet 22 is connected to the second air outlet 11 of the mouthpiece 10. The atomizer 20 is also provided with an air guide tube 23 connecting the tubular body 212 and the second air outlet 11, so that the aerosol released in the tubular body 212 can be further transmitted to the second air outlet 11 for the user to inhale through the air guide tube 23.

[0046] Both the liquid-absorbing element 212 and the liquid-conducting element 213 are made of porous materials, such as cotton fibers, non-woven fabrics, fiberglass ropes, porous ceramics, or porous glass. This allows the liquid-absorbing element 212 and the liquid-conducting element 213 to absorb and transfer the liquid matrix through their internal pores or microporous structures. Correspondingly, the heating element 214 can be bonded to the liquid-conducting element 213 or wound around it by means of printing, deposition, sintering, or physical assembly.

[0047] In some other embodiments, the atomizing component may also include an ultrasonic atomizing element, which may be an atomizing sheet. The atomizing sheet can atomize the liquid matrix flowing onto the atomizing sheet into an aerosol by means of high-frequency vibration. This application does not limit the type of atomizing component, as long as the atomizing component can atomize the liquid matrix into an aerosol.

[0048] If you wish to continue reading Figure 4 In conjunction with reference Figure 6 The atomizer 20 has a first end and a second end arranged opposite to each other along its length. A third air outlet 22 is disposed at the first end, and a base 24 is mounted on the second end. The base 24 provides support for the internal components of the atomizer 20. The base 24 is provided with an electrode hole and a second air inlet 21. The second air inlet 21 is in fluid communication with the atomizing components in the tubular body 215. When the user inhales through the second air outlet 11, external air enters the atomizer 20 through the second air inlet 21, and then flows further into the tubular body 215. It carries the aerosol released in the tubular body 215 and is transported to the second air outlet 11 through the air guide tube 23. The user can then inhale the aerosol by inhaling through the mouthpiece 10.

[0049] An electrode 241 is provided in the electrode hole. The electrode 241 is electrically connected to the heating element 214, and a part of the electrode 241 is exposed on the end face of the base 24. The electrical contact 351 of the power supply assembly 30 is exposed in the first chamber 31. So when the atomizer 20 is housed in the first housing chamber 31, the electrical contact 351 is electrically connected to the electrode 241 of the atomizer 20, and the controller can control the battery cell 34 to provide the electrical energy required for atomization to the atomizer 20.

[0050] like Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, the power assembly 30 also includes a first sealing member 36 disposed on the bracket 33. The first sealing member 36 can be any of silicone, rubber, or latex. The first sealing member 36 and the bracket 33 together define a sealed chamber 37. The first sealing member 36 is provided with a first air inlet 361 and a first air outlet 362. The first air inlet 361 connects the first receiving chamber 31 and the sealed chamber 37, thereby guiding external air flowing into the first receiving chamber 31 into the sealed chamber 37. The first air outlet 362 also connects to the sealed chamber 37 and the first receiving chamber 31, so that when the atomizer 20 is received in the first receiving chamber 31, the first air outlet 362 connects to the second air inlet 21 of the atomizer 20, thereby guiding external air in the sealed chamber 37 into the atomizer 20. In this way, external air does not need to enter the power supply assembly 30 from the bottom, and no air intake channel needs to be provided in the power supply assembly 30, thereby reducing the space occupied by the air intake channel in the power supply assembly 30.

[0051] Furthermore, since external air enters the sealed chamber 37 through the first air inlet 361 and then exits the power assembly 30 through the first air outlet 362, there is no need to provide an air inlet channel through the power assembly 30. This avoids the aerosol generated by atomization from entering the power assembly 30 along the air inlet channel and condensing into condensate in the air inlet channel, thereby preventing damage to the electronic components in the power assembly 30.

[0052] like Figure 3 and Figure 5 As shown, the mouthpiece 10 is provided with a second receiving chamber 12. The mouthpiece 10 and the power assembly 30 can be interconnected. When connected, the first receiving chamber 31 and the second receiving chamber 12 communicate with each other to form a receiving chamber 13 for housing the atomizer 20. When the liquid matrix stored in the atomizer 20 is consumed, the user can directly disassemble the mouthpiece 10 and the power assembly 30 to expose the atomizer 20. The user can then directly remove the atomizer 20 from the receiving chamber 13 for replacement. In some embodiments, the mouthpiece 10 and the atomizer 20 can also be integrated.

[0053] In some embodiments, when the mouthpiece 10 and the power assembly 30 are connected, the mouthpiece 10 provides pressure to the atomizer 20 housed in the receiving chamber 13, thereby holding the atomizer 20 within the receiving chamber 13 and preventing displacement of the atomizer 20 within the receiving chamber 13. Furthermore, the pressure provided by the mouthpiece 10 to the atomizer 20 can be further transmitted to the first seal 36, causing the first seal 36 to elastically abut against the support 33 and the atomizer 20, thereby providing a seal between the support 33 and the atomizer 20 and preventing leakage from the first air outlet 362 during the process of guiding external air to the atomizer 20.

[0054] In a specific embodiment, such as Figure 4 and Figure 5 As shown, an abutment portion 14 extends from the top wall of the second receiving chamber 12 into the second receiving chamber 12. When the atomizer 20 is received in the receiving chamber 13, the abutment portion 14 will abut against the atomizer 20 and provide pressure to the atomizer 20, thereby keeping the atomizer 20 in the receiving chamber 13.

[0055] Additionally, a second seal 15 is provided between the contact portion 14 and the atomizer 20. The second seal 15 can be any of silicone, rubber, or latex. The second seal 15 is elastically abutted between the contact portion 14 and the atomizer 20 to seal the third air outlet 22 of the atomizer 20.

[0056] In some embodiments, such as Figure 7 As shown, when the mouthpiece 10 and the housing 32 of the power assembly 30 are connected to each other, the mouthpiece 10 and the housing 32 define and form a third air inlet 16 for external air to enter the electronic atomizing device; or, the third air inlet 16 can also be provided on the mouthpiece 10. This method can make the second air inlet 16 far away from the bottom of the power assembly 30, so as to avoid blocking the third air inlet 16 when the user holds the electronic atomizing device 100 to inhale, thereby causing the electronic atomizing device 100 to fail to work properly.

[0057] And, in some embodiments, such as Figure 7 As shown, when the atomizer 20 is housed in the housing chamber 13, a gap is maintained between the atomizer 20 and the inner wall of the housing 32. This gap connects the third air inlet 16 and the first air inlet 361. Therefore, when the user inhales through the mouthpiece 10, external air enters the electronic atomizing device 100 through the third air inlet 16, then flows through the gap to the first air inlet 361, and subsequently enters the sealed chamber 37 through the first air inlet 361. Figure 7 As shown in the airflow path R, the air flowing into the sealed chamber 37 is then guided to the atomizer 20 through the second air inlet 21 by the first air outlet 362.

[0058] In some embodiments, such as Figure 1 As shown, the electronic atomizing device 100 has a first end 110 and a second end 120 disposed opposite to each other along its length direction, and a first outer surface 130 and a second outer surface 140 extending between the first end 110 and the second end 120. The surface area of ​​the first outer surface 130 is larger than the surface area of ​​the second outer surface 140. The third air inlet 16 is disposed on the first outer surface 130, thereby effectively preventing the user from blocking the third air inlet 16 when holding the electronic atomizing device 100 for inhalation.

[0059] In some embodiments, such as Figure 4 As shown, the receiving chamber 13 can accommodate multiple atomizers 20. To save space, the multiple atomizers 20 are arranged side by side in the receiving chamber 13. The first sealing member 36 is correspondingly provided with multiple first air outlets 362. The number of first air outlets 362 is consistent with the number of atomizers 20, so that one first air outlet 362 corresponds to one second air inlet 21 of one atomizer 20. In this way, the electronic atomizing device 100 can be configured for both single-inhale and mixed-inhale modes.

[0060] Specifically, each of the multiple atomizers 20 can store a liquid matrix with different components, resulting in different aerosols produced by each atomizer 20. When a user needs to use one of the atomizers 20 for inhalation, i.e., in single-inhalation mode, the user can control the other atomizers 20 to stop working. For example, the user can disconnect the electrical connection between the other atomizers 20 and the battery 34 through a switch circuit. At this time, only the atomizer 20 that the user needs to use will work. After the external air flows to the sealed chamber 37 through the airflow path R, some of the air will enter the atomizer 20 through the first air outlet 362 corresponding to the atomizer 20, thereby carrying the aerosol produced by the atomizer 20 out for the user to inhale.

[0061] Similarly, when the user needs to perform a mixed inhalation mode, the user can control multiple atomizers 20 to start working. After the external air flows to the sealed chamber 37 through the airflow path R, since each atomizer 20 corresponds to a first air outlet 362, the external air further flows into the corresponding atomizer 20 through each first air outlet 362, thereby carrying different flavored aerosols to the mouthpiece 10. When the user inhales through the mouthpiece 10, he / she can inhale the aerosol after the mixture of multiple flavored aerosols.

[0062] And, in some embodiments, such as Figure 4 and Figure 5As shown, the first seal 36 has a first surface facing the first receiving chamber 31, and a partition 363 extends from the first surface toward the first receiving chamber 31. The partition 363 is used to isolate the multiple atomizers 20 from each other, so as to prevent the multiple atomizers 20 from being too close to each other, which would make it inconvenient to remove a single atomizer 20 from the receiving chamber 13 during the replacement of the atomizer 20.

[0063] Furthermore, in some embodiments, such as Figure 5 and Figure 9 As shown, the partition 363 includes an adjacent first inclined surface 3631 and a second inclined surface 3632. The first inclined surface 3631 and the second inclined surface 3632 both extend from the first surface toward the first receiving chamber 31 and are close to each other. This method can avoid interference between the atomizer 20 and the partition 363, which would make it inconvenient to remove the atomizer 20 from the receiving chamber 13 during the replacement of the atomizer 20.

[0064] In some embodiments, such as Figure 9 As shown, the bracket 33 also includes a first protrusion 331 that passes through the sealed chamber 37 and is exposed in the first receiving chamber 31. The first protrusion 331 is hollow so that the power supply contact 351 passes through it, thereby exposing the power contact 351 in the first receiving chamber 31. An abutment boss 3311 is formed on the outer surface of the first protrusion 331. The first seal 36 abuts against the abutment boss 3311, thereby providing support for the first seal 36 by the first protrusion 331, preventing the first seal 36 from becoming loose and affecting the sealing effect of the sealed chamber 37.

[0065] In some embodiments, such as Figure 9 As shown, the first sealing member 36 also includes a second surface facing the sealing chamber 37, and a clamping portion 364 extends from the second surface into the sealing chamber 37. The clamping portion 364 is provided with a clamping space 3641. The bracket 33 also includes a second protrusion 332 extending into the sealing chamber 37. The second protrusion 332 is clamped in the clamping space 3641, thereby firmly assembling the first sealing member 36 onto the bracket 33 and preventing the first sealing member 36 from becoming loose and affecting the sealing effect of the sealing chamber 37.

[0066] 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.
