[0044] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] like Figure 1-Figure 7As shown, the embodiment of the present application provides an electronic atomization device, including an atomization accessory 1, a liquid storage bottle 21, a nozzle 3 and a battery rod 4; the atomization accessory 1 includes an atomization core assembly 11, an atomization cover 12 detachably connected to the atomization core assembly 11, the atomization core assembly 11 has an open cavity 111, and the open cavity 111 refers to a space where a liquid matrix can exist after assembly. The atomization cover 12 can cover the open cavity 111 of the atomization core assembly 11, and the atomization cover 12 keeps the inside of the atomization core assembly 11 clean; the liquid storage bottle 21 is provided with an air duct 211 and a storage cavity 212 separated from each other, and the storage cavity 212 is used to store the liquid matrix, and the storage cavity 212 can be in the shape of a The nozzle 3 is detachably connected to the liquid storage bottle 21 and the battery rod 4 is detachably connected to the atomizer core assembly 11, and provides electrical energy to the atomizer core assembly 11. The nozzle 3, the liquid storage bottle 21, the atomizer core assembly 11 and the battery rod 4 are assembled and connected in sequence along the axial direction. The nozzle 3 is connected to the air channel 211, and the open cavity 111 is connected to the storage cavity 212, so that the liquid matrix in the storage cavity 212 is heated in the atomizer core assembly 11 to form an aerosol, and the aerosol is discharged through the air channel 211 and the nozzle 3. After the electronic atomization device is assembled, the overall shape is cylindrical.

[0046] With such a configuration, on the one hand, the nozzle 3, the liquid storage bottle 21, the atomizer core assembly 11 and the battery rod 4 are all detachably connected, and the user can disassemble the liquid storage bottle 21 and the atomizer core assembly 11 by himself, and refill the liquid storage bottle 21 when the liquid matrix is insufficient; on the other hand, the atomizer core assembly 11 can also be completely disassembled, which is convenient for the user to replace as needed. The atomizer accessory 1 can be equipped with multiple, each of which contains an atomizer core assembly 11 for assembling the electronic atomizer device and an atomizer cover 12 for protecting the atomizer core assembly 11. The atomizer cover 12 ensures that the open cavity 111 of the atomizer core assembly 11 remains clean. When the atomizer core assembly 11 needs to be replaced, the atomizer cover 12 on the new atomizer core assembly 11 is removed, and the new atomizer core assembly 11 is assembled and connected with the liquid storage bottle 21 and the battery rod 4. This solves the problem in the prior art of how to provide an electronic atomizer device that is convenient for users to repeatedly inject liquid matrix and can replace the atomizer core independently. Moreover, when the atomizer core assemblies 11 of the multiple atomizer accessories 1 have different heating powers, the user can replace the atomizer core assemblies 11 at will according to the use requirements, and the replaced atomizer core assemblies 11 are still sealed by the atomizer cap 12 and properly stored.

[0047] It should be noted that, in the electronic atomization device provided in the present application, when the user is in use, the storage chamber 212 of the liquid storage bottle 21 is located above the atomization core assembly 11 , which can ensure that the liquid matrix is smoothly replenished to the atomization core assembly 11 .

[0048] In some preferred embodiments, the electronic atomization device also includes a bottle cap assembly that is detachably connected to the liquid storage bottle 21, and the bottle cap assembly can seal the storage cavity 212, that is, the atomization core assembly 11 can replace the connection position of the bottle cap assembly and be connected to the liquid storage bottle 21; the liquid storage bottle 21 and the bottle cap assembly are combined to form a liquid bottle accessory 2.

[0049] With this arrangement, multiple liquid bottle accessories 2 can be equipped, and different liquid bottle accessories 2 can store liquid matrices of various flavors, and the bottle cap assembly can ensure that the liquid matrices are sealed and kept clean. Moreover, when multiple atomizer accessories 1 and liquid bottle accessories 2 are equipped, users can replace them in groups at will to meet the needs of changing to different flavors. When the liquid storage bottle 21 and the atomizer core assembly 11 need to be replaced, the bottle cap assembly on the new liquid storage bottle 21 is removed, the atomizer cap 12 on the new atomizer core assembly 11 is removed, and the new liquid storage bottle 21 and the new atomizer core assembly 11 are assembled and connected with the suction nozzle 3 and the battery rod 4. The replaced liquid storage bottle 21 is still sealed with the bottle cap assembly to properly preserve the liquid matrix.

[0050] The capacity of the liquid storage bottle 21 may be 10 ml. In addition, the atomizer core assembly 11 may absorb and accommodate 2 ml of liquid matrix.

[0051] Regarding the specific structure of the bottle cap assembly, in some specific embodiments, the bottle cap assembly includes a bottle mouth plug 22, which seals the storage cavity 212. The bottle mouth plug 22 is a silicone member; specifically, the bottle mouth plug 22 extends into the liquid storage bottle 21, seals the bottle mouth, and abuts the end of the vent 211 to achieve sealing of the storage cavity 212.

[0052] In addition, the bottle mouth stopper 22 is preferably provided with a protruding stopper for hand-pinch, so that the user can use it conveniently without contacting the liquid matrix, which is clean and hygienic.

[0053] Furthermore, in some optional embodiments, the bottle cap assembly also includes a protective cover 23, which covers the bottle mouth plug 22. The protective cover 23 is threadedly connected to the liquid storage bottle 21 and is provided with a child lock structure, that is, the bottle mouth plug 22 is sealed in the protective cover.

[0054] With this arrangement, a protective cover 23 is added to the outer side of the bottle stopper 22 to prevent the hidden danger of accidental opening by children and enhance safety.

[0055] It should be noted that the child lock structure can be but is not limited to the child lock structure of the bottle cap commonly used in the prior art, such as the design of the inner and outer covers, where the inner cover can only be rotated when the outer cover is pressed, which will not be elaborated in this article.

[0056] Regarding the connection method between the atomizer core assembly 11 and the liquid storage bottle 21, in some optional embodiments, the atomizer core assembly 11 and the liquid storage bottle 21 are connected by a rotating buckle structure 5. Specifically, the inner wall of one of them is provided with a male buckle of the rotating buckle structure 5, and the other is provided with a female buckle of the rotating buckle structure 5. The male buckle is a protrusion 51, and the female buckle is an L-shaped limiting groove 52. The male buckle slides into the female buckle and rotates to complete the connection and form a limit. With this arrangement, the assembly and disassembly between the atomizer core assembly 11 and the liquid storage bottle 21 are easy to operate, and a small rotation is sufficient. Moreover, the connection is firm and reliable.

[0057] Of course, in addition to the above methods, threaded connection or plug-in connection is also feasible.

[0058] Furthermore, in some preferred embodiments, the outer shell 41 of the battery rod 4 covers the atomizer core assembly 11, and the liquid storage bottle 21 is plugged into the outer shell 41. Specifically, a portion of the liquid storage bottle 21 extends into the outer shell 41, and the inner wall of the outer shell 41 is in close extrusion contact with the outer wall of the liquid storage bottle 21.

[0059] With this arrangement, the atomizer core assembly 11 is not exposed, and the overall appearance of the electronic atomizer device is smooth and beautiful.

[0060] In some specific embodiments, the atomizer core assembly 11 includes an atomizer sleeve 112 and an atomizer core; the atomizer core is assembled in the atomizer sleeve 112 and forms an open cavity 111 with the atomizer sleeve 112. The atomizer core includes a porous matrix capable of absorbing a liquid matrix and a heating element for heating the liquid matrix to form an aerosol, and the heating element generates heat when energized; wherein the atomizer cover 12 and the liquid storage bottle 21 can be detachably connected to the open side of the atomizer sleeve 112, and the battery rod 4 can be electrically connected to the heating element on the opposite side of the open side. It should be known that in order to realize the assembly of the atomizer core in the atomizer sleeve 112, the atomizer core assembly 11 also includes other connecting components arranged between the atomizer sleeve 112 and the atomizer core. This part can follow the design in the prior art, so it will not be repeated in this article.

[0061] With this arrangement, since the atomizer sleeve 112 protects the outside of the atomizer core and is convenient for the user to hold, the replacement of the atomizer core assembly 11 is easier for the user than simply replacing the atomizer core, and will not cause damage or contamination to the atomizer core.

[0062] Specifically, the atomizing cover 12 can be connected to the atomizing sleeve 112 to seal the open cavity 111. The atomizing cover 12 and the atomizing sleeve 112 can be connected by static friction or by a threaded connection. The atomizing cover 12 can be configured as a silicone member.

[0063] In some preferred embodiments, the atomizing sleeve 112 is a transparent member so that the open cavity 111 is visible from the outside. The atomizing sleeve 112 is made of a transparent material, which can be, but is not limited to, transparent silicone, transparent acrylic, and the like.

[0064] With this arrangement, the interior of the open cavity 111 can be seen. Since the open cavity 111 is located below the liquid storage bottle 21 when the electronic atomization device is erected, it is convenient to observe the remaining amount of the liquid matrix of the electronic atomization device so as to inject liquid into the liquid storage bottle 21 in time.

[0065] Regarding the specific structure of the rotating buckle structure 5 formed on the atomizer core assembly 11 and the liquid storage bottle 21, in some specific embodiments, the outer wall of the atomizer sleeve 112 is provided with a protrusion 51 (that is, a male buckle provided with the rotating buckle structure 5), and the inner wall of the liquid storage bottle 21 is provided with an L-shaped limiting groove 52 (that is, a female buckle provided with the rotating buckle structure 5). The atomizer core assembly 11 and the liquid storage bottle 21 are assembled along the axial direction. First, they are plugged in, and the protrusion 51 can enter the L-shaped limiting groove 52 along the axial direction of the liquid storage bottle 21. Then, the atomizer core assembly 11 and the liquid storage bottle 21 are caused to rotate relative to each other, and the protrusion 51 slides relative to the L-shaped limiting groove 52 along the circumference of the liquid storage bottle 21 to form the rotating buckle structure 5.

[0066] With such arrangement, the L-shaped limiting groove 52 and the protrusion 51 can be arranged locally without being designed for the entire periphery, so that a small rotation is sufficient, and the operation is easy.

[0067] In some other specific embodiments, the nozzle 3 is plugged into and unplugged from the liquid storage bottle 21. When the nozzle 3 is plugged into the liquid storage bottle 21, it is squeezed into contact with the liquid storage bottle 21. The portion of the nozzle 3 used to connect with the liquid storage bottle 21 is provided with a circumferentially surrounding drag reduction groove 31. Figure 2 The drag-reducing grooves 31 can be provided with multiple circles and distributed along the insertion and removal direction. In this way, the drag-reducing grooves 31, as a local material reduction design of the nozzle 3, can reduce the problem of high insertion and removal resistance caused by the contact area between the nozzle 3 and the liquid storage bottle 21, making it easier for users to disassemble and assemble the nozzle 3 and the liquid storage bottle 21.

[0068] Of course, in addition to the above-mentioned method, it is also feasible to provide the suction nozzle 3 with a threaded connection with the liquid storage bottle 21 .
