[0031] In some embodiments, referring to Figures 2 to 4 , the first limiting structure 32 includes a first limiting part 321 and a second limiting part 322, the first limiting part 321 and the second limiting part 322 are arranged on both sides of the control board 38 in the extension direction of the barrel 31, and the first limiting part 321 and the second limiting part 322 abut against the control board 38 in the extension direction of the barrel 31 to prevent the control board 38 from moving in the extension direction of the barrel 31.

[0032] In an embodiment, referring to Figure 2 and Figure 3 , the first limiting part 321 is located on the side of the control board 38 away from the first barrel bottom wall 314 in the extension direction of the barrel 31, the first limiting part 321 includes a first protruding part 3211 on the sidewall of the barrel 31, the first protruding part 3211 is arranged protruding into the installation space 311, the first protruding part 3211 is located on the side of the control board 38 facing the battery cell 35 in the extension direction of the barrel 31, and the first protruding part 3211 abuts against the control board 38 in the extension direction of the barrel 31 to limit the movement of the control board 38 toward the battery cell 35 in the extension direction of the barrel 31.

[0033] The width dimension of the gap 312 on the barrel 31 is the dimension of the gap 312 perpendicular to the extension direction of the barrel 31, the thickness direction of the control board 38 is consistent with the extension direction of the barrel 31, the maximum dimension of the control board 38 in the width direction of the gap 312 is equal to or less than the width dimension of the gap 312, so that the control board 38 can be loaded into the installation space 311 from the gap 312. The barrel 31 is generally a cylindrical structure, the control board 38 includes a board body 381, the board body 381 is generally a circular plate structure, the inner diameter of the barrel 31 is slightly larger than the diameter of the board body 381, so that after the control board 38 is loaded into the installation space 311 from the gap 312, the control board 38 as a whole can reciprocate in the extension direction of the barrel 31 in the installation space 311.

[0034] Please refer to Figure 3 In an embodiment, the first protrusion 3211 can correspond to a hook structure, and the first protrusion 3211 is arranged close to the first bottom wall 314 of the cylinder 31 in the extending direction of the cylinder 31. During the movement of the control plate 38 in the extending direction of the cylinder 31 in the installation space 311, the plate body 381 of the control plate 38 can pass over the hook structure under the action of an external force, and abut against the hook structure in the extending direction of the cylinder 31, so as to limit the movement of the control plate 38 towards the battery cell 35.

[0035] In other embodiments, the first protrusion 3211 has a larger size in the radial direction of the cylinder 31, and the control plate 38 can be inserted into the side of the first protrusion 3211 away from the battery cell 35 through the gap 312, so as to abut against the control plate 38 in the extending direction of the cylinder 31 through the first protrusion 3211, thereby limiting the movement of the control plate 38 towards the battery cell 35.

[0036] In an embodiment, the first protrusion 3211 has a plurality of first protrusions 3211 arranged uniformly in the circumferential direction of the cylinder 31, so as to ensure that the surface of the plate body 381 of the control plate 38 is perpendicular to the extending direction of the cylinder 31, and avoid the control plate 38 from tilting and passing over the first protrusion 3211 in the extending direction of the cylinder 31.

[0037] In an embodiment, the first limiting structure 32 can not be provided with the second limiting portion 322, and the first limiting portions 321 can be arranged at intervals in the extending direction of the cylinder 31. The first limiting portion 321 includes the first protrusion 3211, and the plate body 381 of the control plate 38 can be arranged between two first protrusions 3211 arranged at intervals in the extending direction of the cylinder 31. The first protrusions 3211 on both sides of the control plate 38 can abut against the two opposite surfaces of the plate body 381, so as to avoid the movement of the control plate 38 in the extending direction of the cylinder 31. Of course, in this embodiment, the two first protrusions 3211 on both sides of the control plate 38 can form the first limiting portion 321 and the second limiting portion 322, respectively.

[0038] In an embodiment, please refer to Figure 4 The first limiting portion 321 is located on the side of the control plate 38 away from the first bottom wall 314 of the cylinder 31, so as to abut against the control plate 38 in the extending direction of the cylinder 31. The second limiting portion 322 is located on the side of the control plate 38 towards the first bottom wall 314 of the cylinder 31, and the second limiting portion 322 includes an outer protruding structure 3221 arranged on the first bottom wall 314 of the cylinder 31. The outer protruding structure 3221 is arranged protruding towards the control plate 38 in the extending direction of the cylinder 31, and can abut against the plate body 381 of the control plate 38 in the extending direction of the cylinder 31. In this way, the outer protruding structure 3221 cooperates with the first protrusion 3211 to determine the specific position of the control plate 38 in the extending direction of the cylinder 31, thereby avoiding the movement of the control plate 38 in the extending direction of the cylinder 31.

[0039] In some embodiments, referring to Figure 4 The second limiting portion 322 further comprises an outer protruding structure 3221 and a receiving groove 3222 arranged on the first bottom wall 314. In one example, the receiving groove 3222 is arranged on the outer protruding structure 3221.

[0040] The receiving groove 3222 is arranged in the extending direction of the barrel 31 towards the control plate 38. The control plate 38 further comprises an airflow sensor 382 connected to a plate body 381. In the example where the receiving groove 3222 is arranged on the outer protruding structure 3221, the plate body 381 can abut the groove side wall of the receiving groove 3222 in the extending direction of the barrel 31. The groove side wall of the receiving groove 3222 can cooperate with the first protruding portion 3211 to prevent the control plate 38 from moving in the extending direction of the barrel 31. In the example where the receiving groove 3222 is arranged separately from the outer protruding structure 3221, the plate body 381 can abut the outer protruding structure 3221 in the extending direction of the barrel 31. The outer protruding structure 3221 can cooperate with the first protruding portion 3211 to prevent the control plate 38 from moving in the extending direction of the barrel 31.

[0041] The airflow sensor 382 is arranged in the receiving groove 3222. The outer contour of the airflow sensor 382 matches the shape of the receiving groove 3222. The groove side wall of the receiving groove 3222 can abut the airflow sensor 382 in the direction perpendicular to the extending direction of the barrel 31 to limit the movement of the airflow sensor 382 in the plane perpendicular to the extending direction of the barrel 31. Thus, the cooperation between the first limiting portion 321 and the second limiting portion 322 can limit the movement of the control plate 38 in the extending direction of the barrel 31 and in the plane perpendicular to the extending direction of the barrel 31. That is, the relative fixation between the control plate 38 and the barrel 31 is achieved by the first limiting structure 32, which can prevent the position of the conductive electrode 383 on the control plate 38 from changing and can prevent the control plate 38 from being in poor contact with the atomization assembly, thereby improving the reliability of the electrical connection between the power supply assembly 3 and the atomization assembly.

[0042] In one embodiment, during the installation of the control plate 38, the control plate 38 is installed into the installation space 311 from the gap 312, the plate surface of the plate body 381 of the control plate 38 is perpendicular to the extending direction of the cylinder body 31, the operator operates the control plate 38 to move towards the first cylinder bottom wall 314, under the action of the external force, the plate body 381 of the control plate 38 passes over the first protruding part 3211, at the same time, the airflow sensor 382 is inserted into the accommodating groove 3222, the control plate 38 is limited to move in the extending direction of the cylinder body 31 away from the first cylinder bottom wall 314 by the first protruding part 3211, the control plate 38 is limited to move in the extending direction of the cylinder body 31 towards the first cylinder bottom wall 314 by the outer protruding structure 3221 of the accommodating groove 3222 or the outer protruding structure 3221, and the control plate 38 is limited to move in the plane perpendicular to the extending direction of the cylinder body 31 by the cooperation of the accommodating groove 3222 and the airflow sensor 382, so as to fix the position of the control plate 38 in the installation space 311 of the cylinder body 31.

[0043] Of course, in the embodiment in which the airflow sensor 382 is not arranged on the control plate 38, the second limiting part 322 only includes the outer protruding structure 3221, the outer protruding structure 3221 abuts against the control plate 38 in the extending direction of the cylinder body 31 to limit the movement of the control plate 38 towards the first cylinder bottom wall 314, the outer protruding structure 3221 can not be provided with the accommodating groove 3222, the first limiting structure 32 further includes the mouth edge of the gap 312, the width of the gap 312 is slightly smaller than the size of the plate body 381 in the width direction of the gap 312, the cylinder body 31 is made of plastic material, the plate body 381 can be installed into the installation space 311 by passing over the gap 312 under the action of the external force, and the control plate 38 is limited to be taken out of the installation space 311 from the gap 312 by the mouth edge of the gap 312, so as to fix the position of the control plate 38 in the installation space 311 of the cylinder body 31.

[0044] In some embodiments, the battery cell 35 is located on the side of the control plate 38 away from the first cylinder bottom wall 314, the battery cell 35 has a positive electrode connecting end (not shown in the figure) and a negative electrode connecting end (not shown in the figure) towards the control plate 38, the positive electrode connecting end and the negative electrode connecting end are located at the end of the battery cell 35 towards the control plate 38, in the extending direction of the cylinder body 31, the battery cell 35 can be directly electrically connected with the plate body 381 of the control plate 38, the positive electrode connecting end and the negative electrode connecting end of the battery cell 35 can be electrically connected with the plate body 381 of the control plate 38 in the tin soldering mode, or the positive electrode connecting end and the negative electrode connecting end of the battery cell 35 can be electrically connected with the plate body 381 of the control plate 38 in the elastic abutting mode, so as to realize the wireless beam connection design of the battery cell 35 and the control plate 38, and facilitate the automatic assembly of the power supply assembly 3.

[0045] In some embodiments, the first limiting structure 32 can not be provided with the first limiting part 321, i.e. not provided with the first protruding part 3211, and a structure that abuts against the battery cell 35 in the extension direction of the cylinder body 31 can be provided on the cylinder wall of the cylinder body 31. The battery cell 35 abuts against the control board 38 in the extension direction of the cylinder body 31, so as to limit the movement of the control board 38 in the extension direction of the cylinder body 31 by cooperation of the battery cell 35 and the outer protruding structure 3221.

[0046] In some embodiments, for the battery cell 35, please refer to Figure 2 and Figure 3 The cylinder body 31 can be provided in a cylindrical structure, and the battery cell 35 can be provided in a cylindrical structure. In a plane perpendicular to the extension direction of the cylinder body 31, the angle of the cylinder side wall of the cylinder body 31 around the battery cell 35 at the notch 312 is greater than 180°. In a plane perpendicular to the extension direction of the cylinder body 31, the width dimension of the notch 312 is less than the diameter dimension of the battery cell 35. The cylinder body 31 is made of a plastic material with good elastic deformation capability, and the battery cell 35 can be installed into the installation space 311 by overcoming the notch 312 under the action of an external force. After the battery cell 35 is installed into the installation space 311, the edge of the notch 312 interferes with the battery cell 35 in the direction of the notch 312, and the battery cell 35 can be limited from being removed from the installation space 311 through the notch 312 by abutting against the edge of the notch 312.

[0047] In other embodiments, the cross-sectional shape of the cylinder body 31 in the direction perpendicular to the extension direction thereof can also be trapezoidal, and the notch 312 is located on one side of the shorter base of the trapezoid.

In other embodiments, the second protruding part 3231 can directly abut against the battery cell 35 in the extension direction of the barrel 31 to directly limit the movement of the battery cell 35 away from the control panel 38.

[0049] In the embodiment in which the first limiting part 321 includes the first protruding part 3211, the first protruding part 3211 can abut against the battery cell 35 in the extension direction of the barrel 31 to limit the movement of the battery cell 35 in the direction close to the control panel 38 in the extension direction of the barrel 31. Thus, the position of the battery cell 35 in the extension direction of the barrel 31 can be determined by the second protruding part 3231 and the first protruding part 3211, and the position of the battery cell 35 in the mounting space 311 is fixed.

[0050] In the embodiment in which the first limiting part 321 does not include the first protruding part 3211, the battery cell 35 and the control panel 38 can be clamped and fixed between the second protruding part 3231 and the outer protruding structure 3221 in the extension direction of the barrel 31, so as to fix the position of the battery cell 35 in the mounting space 311.

[0051] In some embodiments, referring to Figures 2 to 4 The battery cell 35 in the power supply assembly 3 can be charged. The power supply assembly 3 includes a charging panel 36 electrically connected to the battery cell 35. The charging panel 36 is located in the mounting space 311 and can be electrically connected to the battery cell 35 through a wire harness. The inner wall surface of the barrel 31 is provided with a second limiting structure 34. The first limiting structure 32 and the second limiting structure 34 are located on both sides of the battery cell 35 in the extension direction of the barrel 31. The charging panel 36 abuts against the second limiting structure 34 to at least limit the freedom of the charging panel 36 in the extension direction of the barrel 31. In one embodiment, the second limiting structure 34 abuts against the charging panel 36 in the extension direction of the barrel 31 to limit the movement of the charging panel 36 in the extension direction of the barrel 31. In another embodiment, the second limiting structure 34 not only limits the movement of the charging panel 36 in the extension direction of the barrel 31, but also limits the charging panel 36 from being pulled out of the mounting space 311 in the direction of the gap 312. Thus, the relative fixation of the charging panel 36 and the barrel 31 is achieved.

[0052] The charging plate 36, the control plate 38 and the battery cell 35 can be mounted in the barrel 31, which can realize the integration and modular design of the power supply assembly 3, facilitate the automatic production and assembly of the power supply assembly 3, help to improve the compact structure of the power supply assembly 3, and the charging plate 36, the control plate 38 and the battery cell 35 are relatively fixed with the barrel 31, which can avoid the movement of the control plate 38 or the battery cell 35, and help to reduce the probability of poor contact between the control plate 38 and the atomization assembly. The charging plate 36 has a charging interface 361, and the barrel 31 is provided with a charging channel 318 on the second barrel bottom wall 316, which is in communication with the charging interface 361, so as to facilitate the charging of the battery cell 35 by an external device.

[0053] In an embodiment, referring to Figure 2 and Figure 3 The second limiting structure 34 includes a limiting groove 341, and the slot of the limiting groove 341 is oriented in the same direction as the direction of the notch 312. The charging plate 36 can be inserted into the limiting groove 341 in the slot direction. The surface of the charging plate 36 is perpendicular to the extension direction of the barrel 31. The slot side wall of the limiting groove 341 abuts against the charging plate 36 in the extension direction of the barrel 31, and the movement of the charging plate 36 in the extension direction of the barrel 31 can be limited by the slot side wall of the limiting groove 341.

[0054] The limiting groove 341 has a first slot side wall 3411 and a second slot side wall 3413. The first slot side wall 3411 is located on the side of the charging plate 36 facing the battery cell 35 in the extension direction of the barrel 31. The second slot side wall 3413 is located on the side of the charging plate 36 away from the battery cell 35 in the extension direction of the barrel 31. The first slot side wall 3411 is connected to the barrel side wall, and the second slot side wall 3413 can be formed by a protrusion provided on the second barrel bottom wall 316. The protrusion has two and is arranged on both sides of the charging interface 361. The first slot side wall 3411 and the protrusion forming the second slot side wall 3413 are arranged staggered in a plane perpendicular to the extension direction of the barrel 31, so as to avoid interference between the slot side wall of the limiting groove 341 and the electronic components on the charging plate 36.

[0055] In an embodiment, the charging plate 36 can also be mounted in the same way as the control plate 38, so that the second limiting structure 34 is similar to the first limiting structure 32. The second limiting structure 34 includes a protruding structure arranged on the side wall of the cylinder and a protruding structure arranged on the bottom wall 316 of the second cylinder. After the charging plate 36 is loaded into the mounting space 311 from the gap 312, the charging plate 36 passes the protruding structure on the side wall of the cylinder under the action of an external force in the extension direction of the cylinder 31, so as to abut against the protruding structure on the side wall of the cylinder and the protruding structure on the bottom wall 316 of the second cylinder in the extension direction of the cylinder 31, so as to limit the specific position of the charging plate 36 in the extension direction of the cylinder 31. Compared with the second limiting structure 34 in this embodiment, the structure of arranging the second limiting structure 34 to include the limiting groove 341 and inserting the charging plate 36 into the limiting groove 341 in the direction perpendicular to the extension direction of the cylinder 31 helps to reduce the size of the cylinder 31 in the extension direction, and helps to realize the miniaturization and compact design of the power supply assembly 3.

[0056] In the embodiment in which the second limiting structure 34 includes the limiting groove 341, please continue to refer to Figure 2 and Figure 3 The second limiting structure 34 also includes a hook 3412 arranged on the side wall of the limiting groove 341. The hook 3412 can abut against the charging plate 36 in the direction in which the gap of the limiting groove 341 faces, so as to limit the charging plate 36 from being pulled out of the gap of the limiting groove 341 or the gap 312.

[0057] Specifically, the hook 3412 is arranged on the first side wall 3411 of the limiting groove 341, and the hook 3412 is located at the position of the gap of the limiting groove 341. During the installation of the charging plate 36, the charging plate 36 passes the hook 3412 and is inserted into the limiting groove 341 under the action of an external force. The charging plate 36 is provided with a clamping hole. After the charging plate 36 is installed into the limiting groove 341, the hook 3412 can cooperate with the clamping hole to limit the charging plate 36 from being pulled out of the limiting groove 341.

[0058] In other embodiments, the hook 3412 is not arranged in the second limiting structure 34. The second limiting structure 34 includes the edge of the gap 312 at the position of the limiting groove 341. The size of the charging plate 36 can also be arranged so that the charging plate 36 abuts against the edge of the gap 312 in the direction in which the gap 312 faces, so as to limit the charging plate 36 from being pulled out of the limiting groove 341.

[0059] In an embodiment, please refer to Figure 3The barrel 31 is provided with a slot 317 on the second barrel bottom wall 316, a charging channel 318 is located on the slot bottom wall of the slot 317, and a charging interface 361 on the charging plate 36 is located in the slot 317. The charging interface 361 can be inserted and assembled in the slot 317 in the process of installing the charging plate 36 into the limiting slot 341, so as to limit the position of the charging interface 361 through the slot side wall of the slot 317, and ensure that the charging interface 361 corresponds to the charging channel 318.
