Description

Technical Field

[0001] This application relates to the field of atomization technology, and particularly relates to a battery cell assembly and an atomization device thereof. Background Art

[0002] An aerosol is a colloidal dispersion system formed by solid or liquid small particles dispersed and suspended in a gas medium. Since aerosols can be absorbed by the human body through the respiratory system, it provides a new alternative absorption method for users. An atomization device refers to a device that forms an aerosol by heating or ultrasonic means on a stored atomizable medium. The atomizable medium includes a liquid, a gel, a paste, or a solid aerosol generation matrix. Atomizing these media can deliver inhalable aerosols to users, replacing conventional product forms and absorption methods.

[0003] An atomization device generally includes an atomization assembly and a battery cell assembly. The battery cell assembly is connected to the atomization assembly and electrically connected to the atomization assembly. The battery cell assembly is used to supply power to the atomization assembly, and the atomization assembly can heat the atomizable medium under the action of the electric energy of the battery cell assembly to generate an aerosol. However, due to structural defects in the current atomization assembly, the electrical connection structure is prone to poor contact problems, resulting in the abnormal operation of the atomization device. Summary of the Invention

[0004] Based on this, in view of the problem of poor contact between the battery cell assembly and the atomization assembly, it is necessary to provide a battery cell assembly and an atomization device thereof.

[0005] A battery cell assembly includes:

[0006] A battery tube;

[0007] A battery upper cover, connected to one end of the battery tube and configured to form an installation cavity; and

[0008] A rotating member, limited in the installation cavity. The rotating member is provided with a wire groove for inserting a thimble. The thimble is inserted into the wire groove along a first direction, and an electrical connector is provided in the wire groove;

[0009] Wherein, the battery upper cover limits the rotating member in the first direction and the horizontal direction parallel to the first direction.

[0010] In one embodiment, under the limiting action of the battery upper cover, the rotating member can move relative to the battery upper cover in the horizontal direction and / or rotate around the first direction.

[0011] In one embodiment, the battery upper cover includes a plurality of clamping arms protruding from the battery tube. All the clamping arms are arranged at intervals around the first direction to form the installation cavity. At least part of the ends of the clamping arms away from the battery tube are convexly provided with positioning bosses facing the installation cavity.

[0012] In one embodiment, the side wall of the rotating member includes a contact surface and a non-contact surface. There is a gap between the non-contact surface and the cavity wall of the installation cavity, and the contact surface contacts the cavity wall of the installation cavity.

[0013] In one embodiment, the end of the wire groove away from the battery tube has a guiding section, and the side wall of the guiding section extends inwardly and obliquely from the end away from the battery tube to the end close to the battery tube.

[0014] An atomizing device includes the above-mentioned battery cell assembly.

[0015] In one embodiment, the atomizing device further includes:

[0016] A housing assembly sleeved outside the battery cell assembly. The battery cell assembly can rotate relative to the housing assembly around the first direction to switch between a clamped state and a separated state;

[0017] An atomizing assembly connected to one end of the battery cell assembly. The atomizing assembly has a thimble, and the thimble is inserted into the wire groove of the battery cell assembly.

[0018] In one embodiment, the central axis of the thimble is eccentrically arranged with respect to the central axis of the atomizing assembly.

[0019] In one embodiment, when the battery cell assembly rotates relative to the housing assembly, the rotating member remains stationary relative to the atomizing assembly under the limiting action of the atomizing assembly.

[0020] In one embodiment, the housing assembly is provided with a buckle groove, and the battery cell assembly is provided with a buckle tongue. When the battery cell assembly and the housing assembly are in the clamped state, the buckle tongue is limited in the buckle groove.

[0021] For the above atomizing assembly, the thimble is inserted into the rotating member and electrically connected to the electrical connector in the wire groove. Since the battery upper cover limits the rotating member in the first direction and the horizontal direction parallel to the first direction, the thimble and the electrical connector can always maintain good contact, effectively preventing the silicone from deforming and causing the thimble and the electrical connector to be out of contact or in poor contact, thereby ensuring that the atomizing device can work normally.

Detailed implementation manners

[0038] To make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0039] In the description of the present application, it should be understood that if terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.

[0040] In addition, if terms such as "first" and "second" appear, these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0041] In this application, unless otherwise clearly defined and limited, if terms such as "installed", "connected", "linked", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] In this application, unless otherwise clearly defined and limited, if there is a description such as the first feature being "on" or "under" the second feature, its meaning can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is at a higher horizontal level than the second feature. The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is at a lower horizontal level than the second feature.

[0043] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0044] Refer to Figure 1 , an embodiment of this application provides an atomizing device 100. The atomizing device 100 provided by the embodiment of this application is used to heat a medium to generate an aerosol for user use. Among them, the heating method can be convection, conduction, radiation or a combination thereof. The aerosol generation matrix includes, but is not limited to, materials for medical, health preservation, health, and beauty purposes. For example, the aerosol generation matrix is a liquid medicine or an oil.

[0045] Such as Figure 1 , Figure 2 and Figure 3As shown, the atomizing device 100 includes an atomizing component 20, a battery cell component 40, and a housing component 60. The atomizing component 20 and the battery cell component 40 are mutually connected and electrically connected. The atomizing component 20 is used to store the atomizing medium and heat the atomizing medium under the action of the electric energy of the battery cell component 40 to generate an aerosol for the user to use. The housing component 60 is sleeved outside the battery cell component 40 and is used for connection, protection, etc. During the assembly process of the atomizing device 100, first, the atomizing component 20, the battery cell component 40, and the housing component 60 are separately assembled, then the atomizing component 20 and the housing component 60 are mutually connected, and finally the battery cell component 40 is assembled to form a complete atomizing device 100.

[0046] Please refer to Figure 4 , the atomizing component 20 includes an atomizing tube 21, a central tube 23, and an atomizing unit 25. The atomizing tube 21 is a hollow shell structure with one end open. One end of the central tube 23 faces the open end of the atomizing tube 21, and the other end of the central tube 23 extends to the closed end of the atomizing tube 21. An exhaust passage 232 communicating with the external atmosphere is formed in the central tube 23. In some embodiments, the central axis of the exhaust passage 232 may coincide with the central axis of the atomizing component 20. A liquid storage cavity 212 surrounding the exhaust passage 232 in the circumferential direction is formed in the atomizing tube 21, and the liquid storage cavity 212 is used to store the atomizing medium. The atomizing unit 25 is received in the open end of the atomizing tube 21. One end of the central tube 23 facing the open end of the atomizing tube 21 communicates with the atomizing unit 25, and one end of the central tube 23 communicating with the closed end of the atomizing tube 21 communicates with the external atmosphere.

[0047] The atomizing unit 25 includes a heating base 252, a heating top cover 254, an atomizing core 256, and two thimbles 258. The heating base 252 is connected to the open end of the atomizing tube 21, and the heating top cover 254 is connected to one end of the heating base 252 facing the central tube 23. An atomizing cavity communicating with the exhaust passage 232 is jointly defined between the heating base 252 and the heating top cover 254. The heating top cover 254 is provided with a liquid passage communicating the liquid storage cavity 212 with the atomizing cavity. The atomizing core 256 is received in the atomizing cavity. The atomizing core 256 has an atomizing surface for heating the atomizing medium. The atomizing surface may be located on the bottom surface of the atomizing core 256 to face the open end of the atomizing tube 21, or may be located on the side surface of the atomizing core 256 to face the tube wall of the atomizing tube 21. That is, the atomizing surface is parallel or at an angle to the central axis of the exhaust passage 232. The two thimbles 258 are arranged at intervals. One end of each thimble 258 contacts the atomizing core 256 to be electrically connected to the atomizing core 256, and the other end of each thimble 258 extends out of the heating base 252 to connect to the battery cell component 40.

[0048] Thus, the atomization medium in the liquid storage cavity 212 can flow into the atomization cavity through the liquid-down channel. The atomization core 256 can heat the atomization medium under the action of the electric energy of the battery cell assembly 40 to generate aerosol. The aerosol generated by the atomization of the atomization medium can be discharged from the exhaust channel 232 for the user to use.

[0049] In the following embodiments, the central axis direction of the exhaust channel 232 is defined as the first direction (i.e., Figure 4 the Z direction in Figure 8 ), the interval direction of the two ejector pins 258 is defined as the second direction (i.e., Figure 4 the X direction in

[0050] ), and the direction between the ejector pin 258 and the atomization core 256 is defined as the third direction (i.e., Figure 4 the Y direction in

[0050] ). The first direction, the second direction, and the third direction are perpendicular to each other in pairs.

[0050] Further, in some embodiments, in order to leave enough space for the liquid-down channel to make the liquid-down of the atomization medium smooth, the central axis of the atomization core 256 is offset relative to the central axis of the exhaust channel 232 in the third direction. As a result, the ejector pin 258 in contact with the atomization core 256 is also eccentric relative to the central axis of the exhaust channel 232 in the third direction (i.e., the central axis of the ejector pin 258 is parallel to the central axis of the exhaust channel 232 and spaced in the third direction), which poses a relatively high requirement for the installation direction of the battery cell assembly 40. Otherwise, it will cause poor contact between the battery cell assembly 40 and the atomization assembly 20, and further cause the atomization device 100 to fail to work properly. In other embodiments, the atomization surface of the atomization core 256 is aligned with or set at a certain angle to the central axis of the exhaust channel 232, which can make the aerosol generated by atomization be discharged faster, obtain a larger atomization amount, and also cause the ejector pin 258 to be eccentric relative to the central axis of the exhaust channel 232.

[0051] For the above technical problems, please refer to Figures 5 to 8 as shown, the battery cell assembly 40 of the present application includes a battery tube 41, a battery upper cover 42, a bottom cover 43, a battery 44, a rotating member 45, a circuit board 46, and an electrical connector 47.

[0052] The battery tube 41 has a hollow tubular structure with openings at both ends, and the central axis of the battery tube 41 extends in the first direction. The battery upper cover 42 and the bottom cover 43 are respectively connected to the two axial ends of the battery tube 41, and the battery 44 is accommodated in the battery tube 41 and located between the battery upper cover 42 and the bottom cover 43. The battery upper cover 42 is configured to form an installation cavity, and the rotating member 45 is accommodated in the installation cavity. The rotating member 45 is provided with a wire groove 451 for inserting the thimble 258, and the thimble 258 is inserted into the wire groove 451 along the first direction. The circuit board 46 is disposed in the bottom cover 43, one end of the electrical connector 47 is connected to the circuit board 46, and the other end of the electrical connector 47 extends into the wire groove 451 to be electrically connected to the thimble 258. Wherein, the battery upper cover 42 limits the rotating member 45 in the first direction and the horizontal direction parallel to the first direction.

[0053] In this way, the thimble 258 is inserted into the rotating member 45 and electrically connected to the electrical connector 47 in the wire groove 451. Since the battery upper cover 42 limits the rotating member 45 in the first direction and the horizontal direction parallel to the first direction, the thimble 258 and the electrical connector 47 can always maintain good contact, effectively preventing the silicone from deforming and causing the thimble 258 and the electrical connector 47 to be out of contact or in poor contact, thereby ensuring that the atomizing device 100 can work normally.

[0054] In some embodiments, under the limiting action of the battery upper cover 42, the rotating member 45 can move relative to the battery upper cover 42 in the horizontal direction and rotate around the first direction, so as to perform automatic position adjustment when the thimble 258 is inserted, so that the thimble 258 can be smoothly inserted into the wire groove 451 of the rotating member 45. In other embodiments, under the limiting action of the battery upper cover 42, the rotating member 45 only moves relative to the battery upper cover 42 in the horizontal direction. In other embodiments, under the limiting action of the battery upper cover 42, the rotating member 45 can only rotate around the first direction.

[0055] The battery upper cover 42 is generally in the shape of a hollow rotating body. One end of the battery upper cover 42 is inserted into the battery tube 41, and the other end of the battery upper cover 42 includes a plurality of clamping arms 421 protruding from the battery tube 41. All the clamping arms 421 are arranged at intervals around the first direction to form an installation cavity. At least part of the clamping arms 421 are provided with positioning bosses 4212 protruding towards the installation cavity at the ends away from the battery tube 41. In this way, the rotating member 45 is limited between the plurality of clamping arms 421 in the horizontal direction and can rotate around the first direction. At the same time, the positioning boss 4212 can prevent the rotating member 45 from disengaging from the installation cavity along the first direction.

[0056] Please combine Figure 9 and Figure 10As shown, further, at least one positioning groove 452 is formed on the edge of the rotating member 45. The positioning groove 452 is arranged corresponding to the positioning boss 4212. When the rotating member 45 is installed in the installation cavity, the positioning groove 452 can be aligned with the positioning boss 4212 to snap the rotating member 45 into the installation cavity. After the rotating member 45 is installed in the installation cavity, the rotating member 45 can be rotated to misalign the positioning boss 4212 and the positioning groove 452, thereby preventing the rotating member 45 from disengaging from the installation cavity in the first direction.

[0057] In some embodiments, in order to allow the rotating member 45 to move in the horizontal direction, the side wall of the rotating member 45 includes a contact surface 453 and a non-contact surface 454. There is a gap between the non-contact surface 454 and the cavity wall of the installation cavity, and the contact surface 453 contacts the cavity wall of the installation cavity, thereby leaving space for the movement of the rotating member 45.

[0058] Specifically, in one embodiment, the rotating member 45 is provided with an air inlet hole 455, two wire grooves 451, two wire holes 456, and two connection grooves 457. The air inlet hole 455 is located at the center of the rotating member 45, and the central axis of the air inlet hole 455 coincides with the rotation axis of the rotating member 45. External air can enter the atomization assembly 20 through the air inlet hole 455. The two wire grooves 451 are located on opposite sides in a radial direction of the rotating member 45, and the connection of the center points of the two wire grooves 451 passes through the rotation axis of the rotating member 45. The two wire holes 456 are located on opposite sides in a radial direction of the rotating member 45, and each wire hole 456 is correspondingly located on one side of a wire groove 451. Each wire hole 456 is correspondingly connected to a wire groove 451 through a connection groove 457. The electrical connector 47 is an electrical connection wire. One end of the electrical connector 47 extends out of the battery tube 41, and then bends and extends to sequentially pass through the wire hole 456 and the connection groove 457 and enter the wire groove 451. In another embodiment, the rotating member 45 is only provided with an air inlet hole 455 and two wire grooves 451 without wire holes 456, and the electrical connector 47 is a structure such as an electrical patch and is directly arranged in the wire groove 451.

[0059] The side wall of the rotating member 45 has two contact surfaces 453, and the two contact surfaces 453 are symmetrically arranged with respect to the connection line of the center points of the two wire grooves 451. Therefore, regardless of whether the battery cell assembly 40 is in the normal installation state or the reverse installation state, the rotating member 45 can move in different directions to achieve the contact conduction between the ejector pin 258 and the electrical connector 47.

[0060] Specifically, when the battery cell assembly 40 is in the right-side-up state, the ejector pin 258 is inserted into the wire groove 451 to the right in the second direction. Under the push of the ejector pin 258, the rotating member 45 is squeezed and offset to one side of the installation cavity so that the ejector pin 258 is aligned with the wire groove 451. When the battery cell assembly 40 is in the upside-down state, the ejector pin 258 is inserted into the wire groove 451 to the left in the second direction. Under the push of the ejector pin 258, the rotating member 45 is squeezed and offset to the other side of the installation cavity so that the ejector pin 258 is aligned with the wire groove 451.

[0061] As Figure 5 , Figure 9 shown, further, one end of the wire groove 451 away from the battery tube 41 has a guiding section 4512. The side wall of the guiding section 4512 extends inwardly from the end away from the battery tube 41 to the end close to the battery tube 41. Therefore, during the process of the ejector pin 258 being inserted into the wire groove 451, the end of the ejector pin 258 first contacts the guiding section 4512 and enters the wire groove 451 under the guidance of the inclined extending guiding section 4512. During the process of the ejector pin 258 being inserted into the wire groove 451, the rotating member 45 is offset and slides to one side under the extrusion of the ejector pin 258 so that the central axis of the wire groove 451 coincides with the central axis of the ejector pin 258.

[0062] Please refer to Figure 6 , Figure 11 , the housing assembly 60 is sleeved outside the battery cell assembly 40. The housing assembly 60 is provided with a buckle groove 632, and the battery cell assembly 40 is provided with a buckle tongue 432. The battery cell assembly 40 can rotate relative to the housing assembly 60 about the first direction to switch between the clamped state and the separated state. When the battery cell assembly 40 and the housing 61 are in the clamped state, the buckle tongue 432 is limited in the buckle groove 632. When the battery cell assembly 40 and the housing 61 are in the separated state, the buckle tongue 432 disengages from the buckle groove 632, so that the battery cell assembly 40 can be detached from the housing assembly 60.

[0063] Specifically, the housing assembly 60 includes a housing 61 and an inner bracket 63. The housing 61 is a hollow tubular structure with both ends open. The inner bracket 63 is installed inside one axial end of the housing 61 and is in interference fit with the housing 61. The inner bracket 63 is a hollow ring structure. The inner bracket 63 is provided with two buckle grooves 632. The two buckle grooves 632 are located on opposite sides of the inner bracket 63 in a radial direction of the inner bracket 63. Each buckle groove 632 is in an "L" shape. One end of the buckle groove 632 extends axially along the inner bracket 63 and communicates with one end face of the inner bracket 63. The other end of the buckle groove 632 extends circumferentially along the inner bracket 63. Two buckle tongues 432 are convexly provided on the side wall of the bottom cover 43 of the battery cell assembly 40, and the two buckle tongues 432 are located on opposite sides of the bottom cover 43 in a radial direction of the bottom cover 43. Each buckle tongue 432 is correspondingly arranged with one of the buckle grooves 632 and is mutually clamped.

[0064] Thus, the buckle tongue 432 can first be inserted axially into the buckle groove 632, and then the bottom cover 43 rotates relative to the inner bracket 63 to cause the buckle tongue 432 to be snapped into the buckle groove 632 circumferentially, finally realizing the tool-free installation of the outer shell assembly 60 and the battery cell assembly 40. Conversely, rotating the bottom cover 43 in the reverse direction can pull out the battery cell assembly 40 from the outer shell assembly 60.

[0065] It can be understood that when the battery cell assembly 40 rotates relative to the outer shell 61, the rotating member 45 remains stationary relative to the atomization assembly 20 under the limiting action of the atomization assembly 20. Therefore, the positional relationship between the rotating member 45 and the ejector pin 258 remains unchanged, and the ejector pin 258 and the electrical connection member 47 are always in a conductive state.

[0066] As Figure 12 shown, in some other embodiments, the two buckle grooves 632 are arranged offset in the radial direction of the outer shell 61, and the two buckle tongues 432 are arranged offset in the radial direction of the battery cell assembly 40, so that the operator can easily identify the installation direction to prevent the battery cell assembly 40 from being installed reversely. At the same time, corresponding to the eccentrically arranged ejector pin 258, the wire grooves 451 and the air inlet holes 455 on the rotating member 45 are also eccentrically arranged. The connecting line of the centers of the two wire grooves 451 does not pass through the central axis of the rotating member 45. Therefore, the ejector pin 258 is aligned with the wire groove 451 and can be directly inserted into the wire groove 451 without aligning the two by moving the rotating member 45 in the horizontal direction.

[0067] For the above-mentioned atomization device 100, when the ejector pin 258 is eccentrically arranged, it can ensure that the wire groove 451 is completely aligned with the ejector pin 258, so that the ejector pin 258 is in good contact with the electrical connection member 47 in the wire groove 451, thereby enabling the stable connection between the atomization assembly 20 and the battery cell assembly 40, and further ensuring the normal operation of the atomization device 100.

[0068] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

[0069] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
