[0052] Please refer to Figure 1 and Figure 2 , this application provides an electronic atomization device 100, including: a main body part 1, an atomizer 2, and a battery 3.

[0053] The main body part 1 is provided with a receiving cavity 11 extending in the first direction Y. The atomizer 2 is movably connected to the main body part 1, and at least part of the atomizer 2 is removably received in the receiving cavity 11. Thus, the installation and disassembly between the atomizer 2 and the main body part 1 can be realized, specifically, the atomizer 2 is installed in the receiving cavity 11 opened in the main body part 1, or disassembled from the receiving cavity 11.

[0054] The battery 3 is installed in the main body 1. The main body 1 includes a first electrode 12, which is electrically connected to the battery 3. A portion of the first electrode 12 is exposed or extends into the accommodating cavity 11 in the second direction X. The atomizer 2 includes a second electrode 21. The second electrode 21 is configured to mate with the first electrode 12 along the second direction X when at least a portion of the atomizer 2 is housed within the accommodating cavity 11. When the atomizer 2 is connected to the main body 1, the second electrode 21 mates with the first electrode 12 along the second direction X. When the atomizer 2 is separated from the main body 1, the second electrode 21 detaches from the first electrode 12. When the second electrode 21 mates with the first electrode 12 along the second direction X, the battery 3 can provide electrical energy to the atomizer 2 through the first electrode 12 and the second electrode 21.

[0055] The first direction Y is perpendicular to the second direction X. This allows for better coordination between the first electrode 12 and the second electrode 21, enabling a modular design of the atomizer 2, allowing for easier installation and removal of the entire atomizer 2 from the main body 1, and enabling simple and efficient replacement of the atomizer 2 in the electronic atomization device 100. The above solution establishes a conductive path laterally connecting the atomizer 2 to the main body 1, eliminating the need for components such as electrical contacts in the direction of removal of the atomizer 2 and simplifying the electrical connection structure between the atomizer 2 and the main body 1.

[0056] In some embodiments, see Figures 2 - 6 , a part of the atomizer 2 can be configured to be able to be manipulated by the user so as to move relative to the main body 1, so that the first electrode 12 can be matched or separated from the second electrode 21. Exemplarily, the atomizer 2 can be first inserted into the accommodating cavity 11, and then rotated at a certain angle, so as to be fixed in the accommodating cavity 11. Alternatively, the atomizer 2 is fixed to the inner wall of the accommodating cavity 11 by the cooperation of a magnetic attraction member. Alternatively, the atomizer 2 and the accommodating cavity 11 can be matched and fixed by means of ribs and grooves. When the atomizer 2 is fixed in the accommodating cavity 11, at least a part of the second electrode 21 can be exposed to the side of the atomizer 2 along the second direction X, a part of the first electrode 12 is exposed or extends into the accommodating cavity 11 toward the second direction X, and the first electrode 12 can be docked with the second electrode 21 along the second direction X; when the atomizer 2 is removed from the accommodating cavity 11, the first electrode 12 is separated from the second electrode 21.

[0057] In some embodiments, see Figure 2 、 Figure 3 and Figure 4, the end of the atomizer 2 may be provided with a bottom cover 22, and at least a portion of the bottom cover 22 may be exposed outside the accommodating chamber 11. Thus, the portion of the bottom cover 22 outside the accommodating chamber 11 can be convenient for user operation. Exemplarily, the portion of the bottom cover 22 outside the accommodating chamber 11 may be constructed with a structure suitable for user hand operation. As an example, the suction nozzle 9 of the electronic atomization device 100 may be provided on the main body 1, so that the end of the accommodating chamber 11 close to the suction nozzle 9 is basically closed, thereby providing the user with the ability to manipulate the bottom cover 22 of the atomizer 2 from the bottom end of the accommodating chamber 11, which is beneficial for keeping the suction nozzle 9 hygienic and avoiding contamination. In other examples, the suction nozzle 9 is provided in the atomizer 2 or is an integrated structure with the atomizer 2, and the user can manipulate the suction nozzle 9 to insert a portion of the atomizer 2 into the accommodating chamber 11, and the suction nozzle 9 is exposed to the outside of the accommodating chamber 11.

[0058] The bottom cover 22 can be configured to be operable by a user so as to rotate the bottom cover 22 relative to the main body 1. For example, the bottom cover 22 can be rotated by rotating the portion of the bottom cover 22 located outside the accommodating cavity 11, thereby driving the remaining portion of the atomizer 2 located within the accommodating cavity 11 to rotate. As a result, the second electrode 21 can rotate under the rotation of the bottom cover 22, and further, when the atomizer 2 is rotated to the mating position, it can abut and mate with the first electrode 12 along the second direction X.

[0059] In some embodiments, see Figure 2 、 Figure 3 and Figure 4 The bottom cover 22 is configured to be able to rotate between an unlocked position and a locked position. When the bottom cover 22 is in the unlocked position, the atomizer 2 can be removed from the accommodating cavity 11 and the second electrode 21 is staggered with the first electrode 12; when the bottom cover 22 is in the locked position, the atomizer 2 is prevented from being removed from the accommodating cavity 11 and the second electrode 21 is aligned with the first electrode 12.

[0060] In some embodiments, see Figure 2 、 Figure 3 and Figure 4 The inner wall of the accommodating cavity is circumferentially provided with one of the first protrusion 14 and the first recess 24, and the bottom cover 22 is correspondingly circumferentially provided with the other of the first protrusion 14 and the first recess 24; wherein, when the bottom cover 22 is in the unlocked position, the first protrusion 14 can pass through the first recess 24, so that the atomizer 2 can be inserted into the accommodating cavity 11, or removed from the accommodating cavity 11.

[0061] Exemplarily, the inner wall of the accommodation cavity 11 may be provided with a first protrusion 14 along the circumferential direction, and the atomizer 2 may be provided with a first recess 24 along the circumferential direction. When the atomizer 2 is in the unlocked position, the first protrusion 14 may pass through the first recess 24, so that the atomizer 2 can be assembled to the main body part 1 or removed from the main body part 1.

[0062] In some embodiments, the first protrusion 14 on the inner wall of the accommodation cavity 11 may include a plurality of protrusions spaced apart along the inner wall of the accommodation cavity 11; the first recess 24 may be a recess formed between two protrusions provided along the circumferential direction of the atomizer 2. The positions of the first protrusion 14 and the first recess 24 correspond to each other so that the first protrusion 14 can pass through the first recess 24.

[0063] In some embodiments, the first protrusion 14 may be provided at the connection between the inner wall of the accommodation cavity 11 and the opening of the accommodation cavity 11; the first protrusion 14 may be a boss, a protruding block, or a protruding column, etc. The first recess 24 may be provided on the outer periphery of the bottom cover 22.

[0064] After the atomizer 2 is inserted into the accommodation cavity 11, it is necessary to rotate a certain angle to make the first electrode 12 and the second electrode 21 abut and cooperate. However, it is difficult to accurately grasp the rotation angle. In order to avoid deviation in the cooperation between the first electrode 12 and the second electrode 21.

[0065] In some embodiments, please refer to Figure 2 、 Figure 3 and Figure 4 , the inner wall of the accommodation cavity 11 may further be provided with a first limiting portion 15, and the outer periphery of the atomizer 2 may further be provided with a second limiting portion 25 extending along the first direction Y and corresponding to the position of the first limiting portion 15. The second limiting portion 25 can rotate as the bottom cover 22 rotates. When the bottom cover 22 rotates from the unlocked position to make the second limiting portion 25 abut against the first limiting portion 15, it cannot continue to rotate. At this time, the position of the bottom cover 22 is in the locked position, and the first electrode 12 and the second electrode 21 abut and cooperate. The setting of the first limiting portion 15 and the second limiting portion 25 makes the abutting cooperation between the first electrode 12 and the second electrode 21 more precise.

[0066] In addition, please refer to Figure 3 、 Figure 4 and Figure 5, The cooperation between the first limiting part 15 and the second limiting part 25 can also prevent the atomizer 2 from falling out of the accommodating cavity or prevent the atomizer 2 from being removed from the inside of the accommodating cavity 11. Exemplarily, the first limiting member 15 can be two protruding structures 151 that extend circumferentially along the inner wall of the accommodating cavity and are spaced apart along the first direction Y, and a recess is formed between the two protruding structures 151; the main body of the second limiting member 25 can be a rib 251 disposed on the outer periphery of the atomizer along the first direction, and an extension 252 perpendicular to the rib 251 can be further extended at the middle position of the rib 251. The second limiting member 25 can be a "T" - shaped structure formed by the rib 251 and the extension 252. When the second limiting member 25 rotates relative to the first limiting member 15, the extension 252 in the "T" - shaped structure can be inserted into the recess formed between the two protruding structures 151 of the first limiting member 15. When the rib 251 in the second limiting member 25 abuts against the protruding structure 151 in the first limiting member 15, the extension 252 of the second limiting member 25 is inserted between the two end protruding structures 151. Thus, the cooperation between the first limiting member 15 and the second limiting member 25 can, on the one hand, prevent the atomizer 2 from rotating and ensure the connection between the first electrode 12 and the second electrode 21; on the other hand, it can prevent the atomizer 2 from falling out of the accommodating cavity 11 or prevent the atomizer 2 from being removed from the inside of the accommodating cavity 11.

[0067] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 4 , in order to achieve more efficient and rapid assembly between the atomizer 2 and the main body part 1, a first marking member 13 can be provided at the opening edge of the accommodating cavity 11, and a second marking member 23 corresponding to the first marking member 13 can be provided on the bottom cover 22. Among them, when the second marking member 23 is aligned with the first marking member 13, it can guide the atomizer 2 to be inserted into the accommodating cavity 11. Exemplarily, when the cross - sections of both the bottom cover 22 and the accommodating cavity 11 are circular, there is no reference object for the assembly between the atomizer 2 and the main body part 1, and it is difficult to achieve rapid assembly, and it is also difficult to accurately match between the first electrode 12 and the second electrode 21. Therefore, a first marking member 13 can be provided at the opening edge of the accommodating cavity 11 of the main body part 1, and at the same time, a second marking member 23 corresponding to the first marking member 13 can be provided on the bottom cover 22. When the positions of the first marking member 13 and the second marking member 23 correspond to each other, the atomizer 2 can be inserted into the inside of the accommodating cavity 11 from this position. After being inserted into the inside of the accommodating cavity 11, rotating a certain angle relative to the main body part 1 can achieve the abutment between the first electrode 12 and the second electrode 21.

[0068] Further, a third marking member 13' may be provided on the bottom cover 22, so that the first marking member 13 can correspond to the unlocking position where the atomizer 2 is engaged with the main body portion 1, and the third marking member 13' can correspond to the locking position where the atomizer 2 is engaged with the main body portion 1. When the second marking member 23 on the atomizer 2 aligns with the first marking member 13 on the main body portion, the atomizer 2 is in the unlocking position engaged with the main body portion 1, and the atomizer 2 can be inserted into the receiving cavity 11 or removed from the receiving cavity 11. When the second marking member 23 on the atomizer 2 rotates to align with the third marking member 13' on the main body portion, the atomizer 2 is in the locking position engaged with the main body portion 1, and the atomizer 2 cannot be removed. At this time, the first electrode 12 is docked with the second electrode 21.

[0069] In some embodiments, an elastic member may be provided at the bottom corresponding to the opening of the receiving cavity 11, and the elastic member can provide an assembly feel when the atomizer 2 is inserted into the receiving cavity 11. Exemplarily, the length of the atomizer 2 along the first direction Y may be set to be less than or equal to the depth of the receiving cavity 11, so that when the atomizer 2 is about to be fully inserted into the first receiving cavity 11, it can abut against the elastic member at the bottom of the receiving cavity 11, and the entire side wall of the atomizer 2 can be pushed into the receiving cavity 11 under the pressing of an external force, and then the atomizer 2 is rotated in a set direction and angle to reach the mating position. The abutting fit between the first electrode 12 and the second electrode 21 is achieved.

[0070] Exemplarily, corresponding thread structures may be provided between the outer periphery of the atomizer 2 and the inner wall of the receiving cavity 11, and through thread fitting, after rotating to the mating position, the atomizer 2 can be fixed. Alternatively, the outer periphery of the atomizer 2 and the inner wall of the receiving cavity 11 may also be fixed by the mutual cooperation of snap members. Alternatively, the outer periphery of the atomizer 2 and the inner wall of the receiving cavity 11 may also be fixed by the attraction between magnetic members.

[0071] When it is necessary to disassemble the atomizer 2 from the inside of the receiving cavity 11, it can be rotated by a set angle in the opposite direction of the assembly direction to align the first marking member 13 with the second marking member 23, so that the atomizer 2 can be removed from the inside of the receiving cavity 11.

[0072] In some embodiments, please refer to Figure 2 and Figure 6, the main body part 1 may include a first magnetic member 16, and the atomizer 2 may include a second magnetic member 26 corresponding to the position of the first magnetic member 16. Wherein, when the first magnetic member 16 and the second magnetic member 26 are attracted to each other, it provides an orientation for the atomizer 2 to be received in the receiving cavity 11 along which the first electrode 12 can be aligned with the second electrode 21. Exemplarily, when the atomizer 2 is inserted into the receiving cavity 11, the first magnetic member 16 and the second magnetic member 26 can be attracted to each other, so that the first electrode 12 and the second electrode 21 are in butt joint and cooperation. When the atomizer 2 is inserted into the receiving cavity 11 and there is no butt joint and cooperation between the first electrode 12 and the second electrode 21, the cooperation position between the atomizer 2 and the main body part 1 can be calibrated by the attraction between the first magnetic member 16 and the second magnetic member 26, and the atomizer 2 is rotated again by the attraction force to achieve automatic calibration of the cooperation between the first electrode 12 and the second electrode 21.

[0073] When the first magnetic member 16 and the second magnetic member 26 are separated, the first electrode 12 can be separated from the second electrode 21. Exemplarily, when the atomizer 2 needs to be replaced, the atomizer 2 can be directly pulled out from the inside of the receiving cavity 11 by a pulling force greater than the attraction force between the first magnetic member 16 and the second magnetic member 26. In some other examples, the first magnetic member 16 is arranged at the bottom of the receiving cavity and deviated from the center, and the second magnetic member 26 is arranged on the end face of the atomizer 2 at the other end relative to the manipulable end, and its position is deviated from the center of the end face. In this way, when the user inserts the atomizer 2 into the receiving cavity in any orientation, the attraction force between the first magnetic member 16 and the second magnetic member 26 can correct the deviation, and finally align the first electrode 12 and the second electrode 21.

[0074] Furthermore, in order to enable the first magnetic member 16 and the second magnetic member 26 to be attracted to each other quickly, so that the first electrode 12 and the second electrode 21 can be in butt joint and cooperation quickly. A first marking member 13 can be arranged at the edge of the opening of the receiving cavity 11, and a second marking member 23 can be arranged on the bottom cover 22 of the atomizer 2. Thus, the atomizer 2 can be inserted into the receiving cavity 11 at the position where the first marking member 13 and the second marking member 23 are aligned, and then the first magnetic member 16 and the second magnetic member 26 can be attracted to each other quickly.

[0075] In some embodiments, both the first magnetic member 16 and the second magnetic member 26 can be magnets. Alternatively, one of the first magnetic member 16 and the second magnetic member 26 is a magnet, and the other is a ferromagnetic material.

[0076] In some embodiments, please refer to Figure 2 and Figure 7, a first anti-fooling member 17 may be provided on the inner wall of the accommodation cavity 11, and a second anti-fooling member 27 may be provided on the outer wall of the atomizer 2; the second anti-fooling member 27 is configured to be able to slide relative to the first anti-fooling member 17 along the first direction Y, so that the atomizer 2 can be inserted into the accommodation cavity 11 along the orientation where the first electrode 12 is aligned with the second electrode 21.
