Description

[Technical Field]

[0001] This application relates to the field of atomization technology, and more particularly to a liquid storage component for storing a liquid matrix, as well as an atomizer and electronic atomization device having the liquid storage 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. 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. However, during the transfer of liquid matrix, air bubbles are prone to accumulate in the liquid guiding channel, which will hinder the smooth flow of liquid matrix in the liquid storage components to the atomizing components, resulting in dry burning of the atomizing elements on the atomizing components due to insufficient liquid supply. [Utility Model Content]

[0004] This application provides an atomizer and an electronic atomizing device to solve the problem that when the liquid storage component and the atomizing component of the current atomizer are connected to form a liquid guiding channel, air bubbles tend to accumulate in the liquid guiding channel, thereby hindering the flow of the liquid matrix in the liquid storage component to the atomizing component.

[0005] At least one embodiment of this application provides an atomizer, including:

[0006] A liquid storage assembly, defining a liquid storage chamber for storing a liquid matrix;

[0007] An atomizing assembly, which can be connected to the liquid storage assembly, the atomizing assembly including an atomizing element for atomizing the liquid matrix to generate an aerosol;

[0008] When the atomizing component and the liquid storage component are connected, a first liquid guiding channel and a second liquid guiding channel are established between the atomizing component and the liquid storage component, which connect the liquid storage chamber and the atomizing element. The first liquid guiding channel and the second liquid guiding channel are spaced apart, and the cross-sectional area of ​​at least a portion of the first liquid guiding channel and the cross-sectional area of ​​at least a portion of the second liquid guiding channel are different.

[0009] In one embodiment, the cross-sectional area of ​​the first liquid guiding channel is larger than that of the second liquid guiding channel in the same cross-sectional plane perpendicular to the axis of the atomizer.

[0010] In one embodiment, the cross-sectional shapes of the first liquid guiding channel and the second liquid guiding channel are different.

[0011] In one embodiment, the first liquid channel and the second liquid channel have different equivalent diameters.

[0012] In one embodiment, the difference between the equivalent diameter of the first liquid guiding channel and the second liquid guiding channel is between 0.5 mm and 3.5 mm.

[0013] In one embodiment, the first liquid guiding channel has an equivalent diameter of 2.5 mm to 5.0 mm, or / and the second liquid guiding channel has an equivalent diameter of 1.5 mm to 4.0 mm.

[0014] In one embodiment, both the first liquid guiding channel and the second liquid guiding channel include a first liquid guiding section and a second liquid guiding section connected in sequence. The first liquid guiding section is connected to the liquid storage cavity. The inner diameter of the first liquid guiding channel is larger than the inner diameter of the second liquid guiding channel. An arc surface or inclined surface for guiding the liquid matrix is ​​connected between the first liquid guiding section and the second liquid guiding section. The cross-sectional areas of the two first liquid guiding sections are the same, and the cross-sectional areas of the two second liquid guiding sections are different.

[0015] In one embodiment, the liquid storage assembly includes a first liquid guide column and a second liquid guide column extending in parallel away from the liquid storage cavity, at least a portion of the first liquid guide channel is defined by the first liquid guide column, at least a portion of the second liquid guide channel is defined by the second liquid guide column, and in the same cross-sectional plane perpendicular to the axis of the liquid storage assembly, the equivalent diameter of the first liquid guide column is greater than the equivalent diameter of the second liquid guide column.

[0016] In one embodiment, one of the liquid storage component and the atomizing component is provided with a first liquid guiding hole, and the other is provided with a liquid guiding column for insertion into the first liquid guiding hole, wherein the sections with different cross-sectional areas in the first liquid guiding channel and the second liquid guiding channel are at least partially defined by the liquid guiding column.

[0017] At least one embodiment of this application also provides a liquid storage assembly for an electronic atomizing device, comprising:

[0018] The shell defines a reservoir for storing a liquid matrix;

[0019] A first liquid guiding column connects to the liquid storage cavity and extends away from the liquid storage cavity;

[0020] The second liquid guiding column connects to the liquid storage cavity and extends away from the liquid storage cavity;

[0021] Wherein, the first liquid guiding column defines at least a portion of a first liquid guiding channel for outputting liquid matrix from the liquid storage component, and the second liquid guiding column defines at least a portion of a second liquid guiding channel for outputting liquid matrix from the liquid storage component. In the same cross-sectional plane perpendicular to the axis of the liquid storage component, the cross-sectional area of ​​the first liquid guiding column is greater than the cross-sectional area of ​​the second liquid guiding column.

[0022] At least one embodiment of this application also provides an electronic atomizing device, including the atomizer described in the above embodiments, and a power supply component for connecting to the atomizer and providing electrical power to the atomizer.

[0023] The atomizer provided in the above embodiments designs the cross-sectional area of ​​at least a partial section of the first liquid guiding channel and the cross-sectional area of ​​at least a partial section of the second liquid guiding channel to be different, thereby making the first liquid guiding channel and the second liquid guiding channel have different pressures. This prevents bubbles from rising simultaneously into the liquid storage chamber in the first liquid guiding channel and the second liquid guiding channel, and thus prevents bubbles from getting stuck in the liquid guiding channel, which would cause the atomizing element to burn dry due to insufficient liquid supply.

Detailed Implementation Methods

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] One embodiment of this application provides an atomizer 100, such as Figure 1 and Figure 2As shown, the atomizer 100 includes a liquid storage assembly 10 and an atomizing assembly 20. The housing of 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.

[0037] 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.

[0038] 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.

[0039] like Figure 2 As 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.

[0040] like Figure 2As 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 29 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.

[0041] 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.

[0042] 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.

[0043] In some embodiments, such as Figure 2 As shown, the liquid guiding channel includes a first liquid guiding channel 25 and a second liquid guiding channel 26 extending side by side. The cross-sectional areas of at least a portion of the first liquid guiding channel 25 and at least a portion of the second liquid guiding channel 26 are different. Therefore, when the liquid storage assembly 10 and the atomizing assembly 20 are connected, the first liquid guiding channel 25 and the second liquid guiding channel 26 have different pressures. The air bubbles formed in the first liquid guiding channel 25 and the second liquid guiding channel 26 are also subjected to different pressures. This can prevent the air bubbles from rising simultaneously into the liquid storage chamber 11 in the first liquid guiding channel 25 and the second liquid guiding channel 26, thereby preventing the air bubbles from getting stuck in the liquid guiding channel and hindering the liquid matrix from continuing to flow to the atomizing element, which would cause the atomizing element to burn dry due to insufficient liquid supply.

[0044] The phrase "rising simultaneously" here means that the bubbles in the first liquid guiding channel 25 and the second liquid guiding channel 26 rise to the same height, that is, the bubbles in the first liquid guiding channel 25 and the second liquid guiding channel 26 rise at the same speed in the liquid guiding channel.

[0045] If the cross-sectional areas of the first liquid guiding channel 25 and the second liquid guiding channel 26 are exactly the same, the liquid pressure at the same height in the first liquid guiding channel 25 and the second liquid guiding channel 26 will also be the same. The pressure on the air bubbles formed in the first liquid guiding channel 25 and the second liquid guiding channel 26 will also be the same. As a result, the air bubbles will rise to the liquid storage chamber 11 simultaneously in the first liquid guiding channel 25 and the second liquid guiding channel 26. This method can easily cause the air bubbles to be unable to continue rising due to the force balance in one or two liquid guiding channels and get stuck in the liquid guiding channels. This will prevent the liquid matrix from continuing to flow to the atomizing element in the atomizing assembly 20, which will cause the atomizing element to dry burn due to insufficient liquid supply.

[0046] like Figure 3 As 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.

[0047] In some embodiments, such as Figure 3 As shown, the atomizing assembly 20 is provided with two first liquid guiding holes 28, both of which are connected to the liquid storage component 21. The base 15 is provided with a first liquid guiding column 151a and a second liquid guiding column 151b extending away from the liquid storage cavity 11 and hollow. Both the first liquid guiding column 151a and the second liquid guiding column 151b are provided with liquid outlets 1511, allowing the liquid matrix to flow out of the liquid storage assembly 10. The sealing component 14 is provided with two second liquid guiding holes 141 communicating with the hollow areas of the first liquid guiding column 151a and the second liquid guiding column 151b. Therefore, when the liquid storage assembly 10 is connected to the atomizing assembly 20, the first liquid guiding column 151a and the second liquid guiding column 151b are respectively inserted into the two first liquid guiding holes 28, allowing the liquid matrix in the liquid storage cavity 11 to flow to the liquid storage component 21 through the second liquid guiding holes 141, the guiding column, and the liquid outlets 1511 on the guiding column. Figure 2 The two liquid flow paths R2 are shown in the figure, thus forming the first liquid guiding channel 25 and the second liquid guiding channel 26 mentioned above.

[0048] In some embodiments, the positions of the first liquid guiding hole and the liquid guiding column can also be interchanged. That is, a liquid guiding column can be provided on the atomizing component 20, while a corresponding liquid guiding hole can be provided on the liquid storage component 10.

[0049] In some embodiments, such as Figure 2As shown, at least some sections of the first liquid guiding channel 25 and the second liquid guiding channel 26 have different equivalent diameters, specifically in Figure 2 In this embodiment, the equivalent diameter of the first liquid guiding channel 25 is greater than the equivalent diameter of the second liquid guiding channel 26, thereby making the cross-sectional area of ​​a portion of the first liquid guiding channel 25 greater than the cross-sectional area of ​​a portion of the second liquid guiding channel 26. Of course, in some embodiments, the equivalent diameter of the first liquid guiding channel 25 may be smaller than the equivalent diameter of the second liquid guiding channel 26, thereby making the cross-sectional area of ​​a portion of the first liquid guiding channel 25 smaller than the cross-sectional area of ​​a portion of the second liquid guiding channel 26.

[0050] It should be noted that the cross-sectional shape of the first liquid guiding channel 25 and the second liquid guiding channel 26 can be circular or non-circular. When the cross-sectional shape is circular, the equivalent diameter is the diameter of the circular cross-section, which is the inner diameter of the first liquid guiding channel 25 and the second liquid guiding channel 26.

[0051] Alternatively, in some embodiments, the cross-sectional shapes of the first liquid guiding channel 25 and the second liquid guiding channel 26 are different, thereby giving the first liquid guiding channel 25 and the second liquid guiding channel 26 different cross-sectional areas. For example, the cross-sectional shape of the first liquid guiding channel 25 is circular, while the cross-sectional shape of the second liquid guiding channel 26 is square.

[0052] In some embodiments, in order to create a suitable pressure difference between the first liquid guiding channel 25 and the second liquid guiding channel 26, thereby more effectively preventing air bubbles from getting stuck in the liquid guiding channel, when the equivalent diameter of the first liquid guiding channel 25 is greater than the equivalent diameter of the second liquid guiding channel 26, the difference between the equivalent diameter of the first liquid guiding channel 25 and the equivalent diameter of the second liquid guiding channel 26 is preferably between 0.5 mm and 3.5 mm.

[0053] The equivalent diameters of the first liquid guiding channel 25 and the second liquid guiding channel 26 need to be of appropriate size. Different equivalent diameters result in different pressures in the first liquid guiding channel 25 and the second liquid guiding channel 26, and the pressure on the bubbles in the first liquid guiding channel 25 and the second liquid guiding channel 26 will be different, thereby adjusting the rising speed of the bubbles in the first liquid guiding channel 25 and the second liquid guiding channel 26.

[0054] In some embodiments, the first liquid channel 25 has an equivalent diameter of 2.5 mm to 5.0 mm.

[0055] In some embodiments, the second liquid channel has an equivalent diameter of 1.5 mm to 4.0 mm.

[0056] Alternatively, in some embodiments, the first liquid guiding channel 25 has an equivalent diameter of 2.5 mm to 5.0 mm, while the second liquid guiding channel has an equivalent diameter of 1.5 mm to 4.0 mm.

[0057] In some embodiments, such as Figure 4 As shown, both the first liquid guiding channel 25 and the second liquid guiding channel 26 include a first liquid guiding section 271 and a second liquid guiding section 272 connected in sequence. The first liquid guiding section 271 is connected to the liquid storage chamber 11, and the inner diameter of the first liquid guiding section 271 is larger than the inner diameter of the second liquid guiding section 272. An arc surface 273 for guiding the liquid matrix is ​​connected between the first liquid guiding section 271 and the second liquid guiding section 272. The two first liquid guiding sections 271 have the same cross-sectional area, while the two second liquid guiding sections 272 have different cross-sectional areas. Therefore, when the remaining liquid matrix in the liquid storage chamber 11 is small, the arc surface 73 can guide the liquid matrix into the liquid guiding channel, thereby reducing the waste of liquid matrix.

[0058] In some embodiments, the first liquid guiding section 271 and the second liquid guiding section 272 may also be connected by an inclined plane, so that when the remaining liquid matrix in the liquid storage cavity 11 is small, the liquid matrix is ​​guided to the liquid guiding channel by the inclined plane.

[0059] In some embodiments, the sections with different cross-sectional areas in the first liquid guiding channel 25 and the second liquid guiding channel 26 are arranged symmetrically about the longitudinal axis of the atomizer 100, that is... Figure 4 The two second liquid guiding sections 272 are symmetrically arranged about the longitudinal axis L of the atomizer 100. This symmetrical arrangement further reduces the probability of air bubbles getting stuck in the liquid guiding channel. That is, within the same cross-sectional plane perpendicular to the axis L of the atomizer 100, for example in... Figure 5 Within the cross-sectional plane shown, the cross-sectional areas of the first liquid guiding channel 25 and the second liquid guiding channel 26 are different, specifically in... Figure 5 In this embodiment, the cross-sectional area of ​​the first liquid guiding channel 25 is larger than the cross-sectional area of ​​the second liquid guiding channel 26. Of course, in other embodiments, the cross-sectional area of ​​the first liquid guiding channel 25 may also be smaller than the cross-sectional area of ​​the second liquid guiding channel 26.

[0060] In some embodiments, such as Figure 4 As shown, at least a portion of the two second liquid-conducting sections 272 are defined by the first liquid-conducting column 151a and the second liquid-conducting column 151b, respectively. That is, at least a portion of the sections with different cross-sectional areas in the first liquid-conducting channel 25 and the second liquid-conducting channel 26 are respectively disposed on the first liquid-conducting column 151a and the second liquid-conducting column 151b, thereby giving the first liquid-conducting column 151a and the second liquid-conducting column 151b different cross-sectional areas, for example... Figure 5In the embodiment described, within the same cross-sectional plane perpendicular to the axis L of the liquid storage assembly 10, the cross-sectional area of ​​the first liquid guiding column 151a is larger than that of the second liquid guiding column 151b. Of course, in other embodiments, within the same cross-sectional plane perpendicular to the axis L of the liquid storage assembly 10, the cross-sectional area of ​​the first liquid guiding column 151a may also be smaller than that of the second liquid guiding column 151b; it is sufficient that the two liquid guiding columns have different cross-sectional areas.

[0061] Since the base 15 needs to provide support for the seal 14, the base 15 needs to be made of a material with a certain rigidity and strength. For example, the base 15 can be made of plastic material. Thus, the first liquid guiding column 151a and the second liquid guiding column 151b also have a certain rigidity and strength, so as to maintain the constant inner diameter of different sections of the cross-sectional area in the first liquid guiding channel 25 and the second liquid guiding channel 26, and avoid deformation of the inner diameter of different sections of the cross-sectional area, which would cause bubbles to easily accumulate in the liquid guiding channel.

[0062] Alternatively, in some embodiments, the sections with different cross-sectional areas in the first liquid guiding channel 25 and the second liquid guiding channel 26 may also be asymmetrically arranged. For example, the upper part of the first liquid guiding channel 25 and the lower part of the second liquid guiding channel 26 may have the same cross-sectional area, while the lower part of the first liquid guiding channel 25 and the upper part of the second liquid guiding channel 26 may have different cross-sectional areas.

[0063] Alternatively, in some embodiments, the upper portion of the first liquid guiding channel 25 and the lower portion of the second liquid guiding channel 26 have different cross-sectional areas, while the lower portion of the first liquid guiding channel 25 and the upper portion of the second liquid guiding channel 26 have the same cross-sectional area. It is sufficient that at least some sections of the first liquid guiding channel 25 and the second liquid guiding channel 26 have different cross-sectional areas.

[0064] In some embodiments, such as Figure 2 As shown, in order to further reduce the probability of bubbles getting stuck in the liquid guiding channel, both the first liquid guiding channel 25 and the second liquid guiding channel 26 extend along the length direction of the atomizer 100, so that the bubbles can smoothly rise into the liquid storage chamber 11 along the first liquid guiding channel 25 and the second liquid guiding channel 26.

[0065] One embodiment of this application also provides an electronic atomizing device, which can be found in [reference needed]. Figure 6 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.

[0066] In an alternative implementation, for example Figure 6As 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.

[0067] 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 6 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.

[0068] exist Figure 6 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.

[0069] 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.

[0070] Further in Figure 6 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.

[0071] 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.
