DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] In the description of this application, "plurality" means at least two, such as two, three, etc., unless otherwise clearly defined. In this application, unless otherwise clearly defined and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0031] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0032] In the description of this application, it should be understood that the terms "inside", "outside", "upper", "bottom", "front", "back" and the like indicate directions or positional relationships (if any) based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0033] It should also be noted that, in the embodiments of the present application, the same figure mark is used to represent the same component or the same part. For the same parts in the embodiments of the present application, the figure may only mark one of the parts or components as an example. It should be understood that the figure mark also applies to other identical parts or components.

[0034] The electronic atomization device generally includes a battery assembly and an atomizer. The battery assembly is used to power the atomizer, and the atomizer is used to heat the atomization medium and atomize it to form an aerosol after power is turned on. At present, the battery assembly and the atomizer are generally connected by magnetic adsorption. However, the size of the magnet and the magnetized object in the magnetic adsorption method is easily limited by the size of the battery assembly and the atomizer. If the size of the magnet and the magnetized object is too small, the magnetic force between the magnet and the magnetized object will be small, and the atomizer will easily fall off. At the same time, the parts cost of the magnet and the magnetized object is high, and there are many assembly processes.

[0035] In order to solve the above problems, an embodiment of the present application provides an electronic atomization device, by respectively arranging a first clip 121 and a second clip 213 on the atomizer 100 and the battery assembly 200, and the first clip 121 and the second clip 213 are mutually engaged to form a connection between the atomizer 100 and the battery assembly 200, thereby not only making the connection between the atomizer 100 and the battery assembly 200 firm and not easy to fall off, but also reducing the magnet and the magnetized object, saving costs, and reducing the assembly process of the entire electronic atomization device.

[0036] Please also read Figures 1 to 7 The embodiment of the present application provides an electronic atomization device, including an atomizer 100 and a battery assembly 200, wherein the atomizer 100 is formed with a first buckle 121, and the battery assembly 200 is formed with a second buckle 213, and the first buckle 121 is snap-fitted with the second buckle 213; a guide structure 300 is also formed between the atomizer 100 and the battery assembly 200, and the guide structure 300 is used to guide the atomizer 100 and the battery assembly 200 to circumferentially align so that the first buckle 121 and the second buckle 213 are snap-fitted, and the guide structure 300 is also used to limit the relative rotation of the atomizer 100 and the battery assembly 200 after the first buckle 121 and the second buckle 213 are snap-fitted.

[0037] The electronic atomization device provided in the embodiment of the present application has a first snap 121 formed on the atomizer 100, and a second snap 213 formed on the battery assembly 200, and the first snap 121 and the second snap 213 are snapped together, so that the connection between the atomizer 100 and the battery assembly 200 can be formed by snapping. This connection method not only makes the atomizer 100 and the battery assembly 200 firmly connected and not easy to fall off, but also does not require parts such as magnets and magnetized parts to achieve the connection between the atomizer 100 and the battery assembly 200, thereby reducing the cost of the electronic atomization device and also reducing the parts assembly process. In addition, by setting the guide structure 300, not only can the atomizer 100 and the battery assembly 200 be guided to rotate to a circumferential position before assembly to ensure that the first buckle 121 and the second buckle 213 can be accurately buckled, but also the relative rotation of the atomizer 100 and the battery assembly 200 can be restricted after the first buckle 121 and the second buckle 213 are buckled, so as to improve the connection stability of the atomizer 100 and the battery assembly 200.

[0038] In one embodiment, see Figures 1 to 4 The atomizer 100 and the battery assembly 200 are arranged in a longitudinal sleeve arrangement, and the first buckle 121 and the second buckle 213 are buckled with each other in the longitudinal direction. The longitudinal direction refers to the direction parallel to the vertical direction or substantially parallel to the vertical direction when the electronic atomizer device is placed vertically. Figure 2 When the atomizer 100 and the battery assembly 200 are close to each other or are connected to each other in the longitudinal direction, the first buckle 121 and the second buckle 213 are connected in the longitudinal direction, thereby limiting the atomizer 100 and the battery assembly 200 in the longitudinal direction.

[0039] In one embodiment, see Figure 3 and Figure 4 The battery assembly 200 is at least partially sleeved on the outside of the atomizer 100, and the first buckle 121 and the second buckle 213 are engaged with each other to limit the movement of the atomizer 100 away from the battery assembly 200. In addition, a step 146 is formed on the outer peripheral wall of the atomizer 100. When the first buckle 121 and the second buckle 213 are engaged, the step 146 abuts against the end of the battery assembly 200 to limit the movement of the atomizer 100 toward the battery assembly 200, thereby realizing the longitudinal limitation of the atomizer 100 and the battery assembly 200.

[0040] In one embodiment, see Figure 3The battery assembly 200 includes a battery shell 210 and a battery 220 installed on the battery shell 210. The top of the battery shell 210 is sleeved on the bottom of the atomizer 100. The second buckle 213 is formed on the battery shell 210 and is connected to the atomizer 100 through the battery shell 210, thereby realizing the connection between the battery assembly 200 and the atomizer 100.

[0041] In one embodiment, see Figure 4 , Figure 8 and Fig. 9 , the first buckle 121 is formed on the outer periphery of the atomizer 100, and the second buckle 213 is formed on the inner periphery of the battery shell 210, so that the atomizer 100 and the battery assembly 200 can be connected at the periphery through the first buckle 121 and the second buckle 213. It can be understood that in other embodiments of the present application, the first buckle 121 can also be formed on the side of the atomizer 100 facing the battery assembly 200, and the second buckle 213 can also be formed on the side of the battery assembly 200 facing the atomizer 100, which is not limited here.

[0042] In one embodiment, see Figure 4 , two symmetrically arranged first buckles 121 are distributed on the outer periphery of the atomizer 100, and two symmetrically arranged second buckles 213 are distributed on the inner side wall of the battery shell 210. The two first buckles 121 are connected with the two second buckles 213 in a one-to-one correspondence to improve the connection reliability between the atomizer 100 and the battery assembly 200. It can be understood that in other embodiments of the present application, the number of the first buckles 121 can also be one, three or more than three, and the number of the second buckles 213 can also be one, three or more than three, which is not limited here.

[0043] In one embodiment, see Figure 4 The first buckle 121 and / or the second buckle 213 include an elastic arm 1211, that is, at least one of the first buckle 121 and the second buckle 213 includes an elastic arm 1211, wherein the setting of the elastic arm 1211 enables the buckling and disengagement between the buckles to be achieved through the deformation of the elastic arm 1211 during the relative movement between the first buckle 121 and the second buckle 213.

[0044] In a specific embodiment, see Figure 4 and Figure 7The first clip 121 includes an elastic arm 1211 and a first clamping block 1212 formed on the elastic arm 1211, and the second clip 213 includes a second clamping block 2131 formed on the battery assembly 200. When the first clamping block 1212 and the second clamping block 2131 move relative to each other, the elastic arm 1211 can be squeezed to deform the elastic arm 1211, thereby achieving the connection and separation between the first clamping block 1212 and the second clamping block 2131.

[0045] In one embodiment, see Figure 4 and Figure 7 The first buckle 121 has a first buckle surface 1213, and the second buckle 213 has a second buckle surface 2132. The first buckle surface 1213 and the second buckle surface 2132 are parallel to each other, and the first buckle surface 1213 is inclined at 15-60 degrees relative to the longitudinal direction. Specifically, the first buckle surface 1213 can be inclined at 15, 20, 25, 30, 35, 40, 45, 50, 55 or 60 degrees relative to the longitudinal direction, and the second buckle surface 2132 can also be inclined at 15, 20, 25, 30, 35, 40, 45, 50, 55 or 60 degrees relative to the longitudinal direction. In this embodiment, since the first buckle 121 and the second buckle 213 are snap-connected along the longitudinal direction, by setting the first buckle surface 1213 and the second buckle surface 2132 to be inclined relative to the longitudinal direction, a relatively longitudinal force is created between the first buckle 121 and the second buckle 213, so that the first buckle 121 can be snapped into the second buckle 213 along the longitudinal direction under the action of an external force, and the first buckle 121 can also be detached from the second buckle 213 along the longitudinal direction under the action of an external force.

[0046] In one embodiment, see Figure 6 , Figure 8 and Fig. 9 The guide structure 300 includes a protrusion 310 and a recessed portion 320, and the protrusion 310 and the recessed portion 320 are plugged together in the longitudinal direction to guide the first buckle 121 and the second buckle 213 to be clamped in the longitudinal direction; the protrusion 310 is formed on the atomizer 100, and the recessed portion 320 is formed on the battery assembly 200; or, the protrusion 310 is formed on the battery assembly 200, and the recessed portion 320 is formed on the atomizer 100. Taking the protrusion 310 formed on the battery assembly 200 and the recessed portion 320 formed on the atomizer 100 as an example, by setting the protrusion 310 and the recessed portion 320, when the protrusion 310 and the recessed portion 320 are not correspondingly set, the side of the atomizer 100 facing the battery assembly 200 will be as follows Figure 7As shown, the protrusion 310 abuts against the protrusion 310 and cannot be fully assembled. When the atomizer 100 is rotated to a suitable position, the protrusion 310 and the recess 320 are correspondingly arranged, and the protrusion 310 can be inserted into the recess 320. At this time, the first buckle 121 and the second buckle 213 are correspondingly arranged in the longitudinal direction, so that when the protrusion 310 is inserted into the recess 320, the first buckle 121 and the second buckle 213 are connected in the longitudinal direction. In this embodiment, the arrangement of the protrusion 310 and the recess 320 can ensure that the first buckle 121 and the second buckle 213 are connected in the longitudinal direction. At the same time, due to the cooperation of the protrusion 310 and the recess 320, the atomizer 100 and the battery assembly 200 cannot rotate relative to each other, thereby ensuring the assembly reliability between the atomizer 100 and the battery assembly 200.

[0047] In one embodiment, see Figure 5 , Figure 6 , Figure 8 and Fig. 9 The battery assembly 200 includes a battery shell 210, which is sleeved on the bottom of the atomizer 100, a protrusion 310 is formed on the inner peripheral wall of the battery shell 210, and a recess 320 is formed on the outer peripheral wall of the atomizer 100. The recess 320 is formed on the outer peripheral wall of the atomizer 100, which simplifies the processing, and also makes the recess 320 and the first buckle 121 both formed on the outer peripheral wall of the atomizer 100, which is conducive to the formation of the elastic arm 1211 on the first buckle 121.

[0048] In one embodiment, see Figure 6 , Figure 8 and Fig. 9 The protrusion 310 has a first limiting surface 311, and the recessed portion 320 has a second limiting surface 321. When the protrusion 310 is inserted into the recessed portion 320 along the longitudinal direction, the first limiting surface 311 and the second limiting surface 321 fit together to limit the relative rotation of the atomizer 100 and the battery assembly 200.

[0049] Specifically, the first limiting surface 311 is a plane from the protrusion 310 to the recessed portion 320, and the second limiting surface 321 is a plane from the recessed portion 320 to the protrusion 310. Both the first limiting surface 311 and the second limiting surface 321 are planes extending in the longitudinal direction. When the first limiting surface 311 abuts against the second limiting surface 321, the relative rotation of the atomizer 100 and the battery assembly 200 can be limited. It can be understood that in other embodiments of the present application, the first limiting surface 311 and the second limiting surface 321 may not be planes, for example, they may be arcuate surfaces or curved surfaces that fit each other, which is not the only limitation here.

[0050] Optionally, see Figure 7The raised portion 310 may be formed by connecting two bent plates formed on the inner wall of the battery shell 210. The top side of the raised portion 310 is a third limiting surface 312. The third limiting surface 312 is a plane. The third limiting surface 312 of the raised portion 310 is used to abut against the bottom side of the atomizer 100 or the bottom side of the first buckle 121 to limit the atomizer 100 that has not been rotated into place from being assembled in place along the longitudinal direction. The first limiting surface 311 is a plane of the raised portion 310 facing the recessed portion 320. It can be understood that in other embodiments of the present application, the raised portion 310 may also be a solid convex block convexly arranged on the inner wall of the battery shell 210, which is not the only limitation here.

[0051] Optionally, see Figure 6 The recessed portion 320 is a notch formed at the bottom edge of the atomizer 100 , the recessed portion 320 passes through the outer wall of the atomizer 100 , and the recessed portion 320 passes through the bottom of the atomizer 100 , and the second limiting surface 321 is the inner wall of the recessed portion 320 facing the raised portion 310 .

[0052] In one embodiment, see Figure 8 The battery shell 210 is provided with two protrusions 310 corresponding to each second buckle 213, and the two protrusions 310 are provided on opposite sides of the second buckle 213 along the circumferential direction; correspondingly, please refer to Fig. 9 , the atomizer 100 is provided with two recessed parts 320 corresponding to each first buckle 121, and the two recessed parts 320 are arranged on opposite sides of the first buckle 121 along the circumferential direction. When the two protrusions 310 and the two recessed parts 320 are arranged one by one along the longitudinal direction, the atomizer 100 and the battery shell 210 can be relatively slid along the longitudinal direction, so that the two protrusions 310 are respectively inserted into the two recessed parts 320, and the first buckle 121 and the second buckle 213 are connected. In this embodiment, by providing two groups of protrusions 310 and recessed parts 320, it is possible to ensure that the first buckle 121 and the second buckle 213 are stably clamped in the circumferential direction, and at the same time, the relative rotation of the atomizer 100 and the battery shell 210 can be limited. In addition, it is also convenient for users to quickly find the clamping position, thereby improving the user experience.

The lower atomizing seat 120 is snap-connected with the outer shell 142, the bottom of the lower atomizing seat 120 extends out of the bottom end of the outer shell 142, and the first buckle 121 and the recessed portion 320 are both formed on the top peripheral wall of the lower atomizing seat 120.

[0057] It is understandable that in other embodiments of the present application, the protrusion 310 may also be formed on the side of the atomizer 100 facing the battery assembly 200, and the recess 320 may be formed on the side of the battery assembly 200 facing the atomizer 100, which is not a sole limitation here.

[0058] In one embodiment, the protrusion 310 is cylindrical, and the protrusion 310 is disposed away from the central axis of the battery assembly 200; and / or, there are multiple protrusions 310.

[0059] Among them, when the atomizer 100 and the battery assembly 200 are both cylindrical, and the protrusion 310 is also cylindrical, in order to prevent the atomizer 100 from rotating relative to the battery assembly 200 after the first buckle 121 and the second buckle 213 are engaged with each other, the protrusion 310 needs to be set away from the central axis of the battery assembly 200, so as to limit the rotation of the atomizer 100; alternatively, the number of the protrusions 310 can be set to multiple, and the multiple protrusions 310 are arranged at intervals, so as to jointly limit the rotation of the atomizer 100; alternatively, the protrusion 310 can be set eccentrically and multiple protrusions 310 can be set, so as to limit the rotation of the atomizer 100.

[0060] It can be understood that in other embodiments of the present application, when the protrusion 310 is non-cylindrical, even if the protrusion 310 is set at the center of the battery assembly 200, the outer peripheral wall of the protrusion 310 and the inner peripheral wall of the recessed portion 320 can also form a rotation restriction on the atomizer 100. At this time, the position and number of the protrusion 310 may not be restricted, and no sole restriction is made here.

[0061] In another embodiment of the present application, the atomizer 100 and the battery assembly 200 are arranged in a longitudinal sleeve, the cross section of the outer peripheral wall of the atomizer 100 is non-circular, the cross section of the inner peripheral wall of the battery assembly 200 is non-circular, and the outer peripheral wall of the atomizer 100 and the inner peripheral wall of the battery assembly 200 jointly form a guide structure 300. In this embodiment, by setting the atomizer 100 and the battery assembly 200 to be non-circular structures, the atomizer 100 and the battery assembly 200 cannot rotate relative to each other after being sleeved with each other, and the sleeve connection direction of the atomizer 100 and the battery assembly 200 is unique, so that the first buckle 121 and the second buckle 213 can be guided to form a snap connection.

[0062] Optionally, the cross-section of the outer wall of the atomizer 100 may be elliptical, racetrack-shaped or other irregular shapes, and the cross-section of the inner wall of the battery assembly 200 may also be elliptical, racetrack-shaped or other irregular shapes.

[0063] In this embodiment, the surface shapes of the atomizer 100 and the battery assembly 200 are specially designed to achieve sleeve guidance and rotation restriction between the atomizer 100 and the battery assembly 200, and the structural design is simple and the cost is low.

[0064] Specifically, the battery assembly 200 includes a battery shell 210, the top of the battery shell 210 is sleeved on the bottom of the atomizer 100, and the top cross section of the battery shell 210 is non-circular, and the bottom cross section of the atomizer 100 is non-circular. When assembling, it is only necessary to align the bottom of the atomizer 100 with the top of the battery shell 210 axially, and then push the atomizer 100 and the battery shell 210 axially until the first buckle 121 and the second buckle 213 form a snap connection, so that the atomizer 100 and the battery shell 210 can be assembled; when disassembling, it is only necessary to separate the atomizer 100 and the battery shell 210 axially by external force, so that the first buckle 121 and the second buckle 213 can be separated, and the atomizer 100 and the battery shell 210 can be separated, and the disassembly and assembly are convenient.

[0065] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
