In the present embodiment, as shown in fig. 1 and 3, the mounting base 1 is provided with a mounting hole 11, and preferably, the mounting hole 11 is a circular through hole penetrating through the mounting base 1. The control plate 2 is fastened to an end surface of one end of the mounting hole 11. Specifically, the end face is convexly provided with at least two positioning columns 12, and correspondingly, the control plate 2 is provided with at least two positioning holes 21. Wherein, the line of the at least two positioning columns 12 does not pass through the center of the mounting hole 11. Namely, the at least two positioning pillars 12 are eccentrically disposed. The position relationship between the control panel 2 and the mounting base 1 is uniquely determined by the cooperation between the at least two positioning holes 21 and the at least two positioning holes 21. The positioning columns 12 and the corresponding positioning holes 21 may be in interference fit or may be in clearance fit. Preferably, the positioning hole 21 and the positioning column 12 are in interference fit to fasten the control plate 2. In practical application, the control board 2 and the end face may be provided with first connection holes 22, and then the control board 2 is fastened to the mounting base 1 by sequentially passing through the control board and the two first connection holes 22 on the end face through a corresponding number of connectors, so that the control board 2 is attached to the end face and closes one end of the mounting hole 11.

As shown in fig. 2, the rotating mechanism 3 passes through the other end of the mounting hole 11, and is partially accommodated in the mounting hole 11. Further, the rotating mechanism 3 includes a rotating member 31, a connecting assembly 33, and a knob 32. The rotation member 31 is completely received in the mounting hole 11 and is opposite to the control panel 2. I.e., there is a gap between the rotation member 31 and the control plate 2. The rotating member 31 is in clearance fit with the mounting hole 11 and can rotate in the mounting hole 11. The rotating member 31 is a structure adapted to the mounting hole 11, and since the mounting hole 11 is a circular through hole in this embodiment, the rotating member 31 is a cylindrical structure.

Referring to fig. 1 and 2, the connecting assembly 33 includes a connecting column 332 and an elastic arm 331, the connecting column 332 is fastened to the rotating member 31, and correspondingly, a second connecting hole 311 is axially formed in one end of the rotating member 31 facing the control board 2. Preferably, the second connection hole 311 is located at the center of the rotation member 31 such that the connection assembly 33 coincides with the rotation center of the rotation member 31. One end of the connecting column 332 is provided with a pressing cap, and the other end of the connecting column is inserted into the second connecting hole 311 and is in interference fit with the second connecting hole 311. One end of the connecting column 332 provided with a pressing cap extends out of the second connecting hole 311, and a gap exists between the pressing cap and the rotating member 31. One end of the elastic arm 331 is sleeved on the connecting column 332, is located between the pressing cap and the rotating piece 31, and is pressed between the connecting column 332 and the rotating column through the pressing cap. The other end of the elastic arm 331 is suspended in the gap between the rotating member 31 and the control panel 2, and is elastically abutted to the control panel 2. In practical applications, the connecting post 332 may be a pin with a cap or a screw with a cap.

Preferably, as shown in fig. 2, the elastic arm 331 is a Z-shaped elastic sheet made of an elastic material, and includes a fixing section 3311, a connecting section 3312 and a contacting section 3313, wherein the fixing section 3311 is sleeved on the connecting column 332 and is attached to the rotating member 31 through the pressing cap. The connecting section 3312 is connected to the fixing section 3311 and the contact section 3313, respectively. The contact section 3313 is attached to the control board 2, and at least two contact portions 6 are convexly provided at one side close to the control board 2. The at least two contact portions 6 are arranged at intervals, elastically abut against the control board 2 and are electrically connected with the contact pieces 23 respectively. In the embodiment, at least two contact parts 6 are arranged to increase the contact area between the connecting assembly 33 and each contact piece 23, and as long as any one of the contact parts 6 is in electrical contact with one of the contact pieces 23, the circuit on the control board 2 can be conducted, so that the power of the electronic cigarette can be adjusted. In practical application, the part of the at least two contact parts 6 abutting against the control plate 2 is an arc transition surface, so that the at least two contact parts 6 form smooth contact with the control plate 2, which is beneficial to reducing the contact resistance of the at least two contact parts 6 and the control plate 2 and reducing the scraping and abrasion of the control plate 2.

Further, as shown in fig. 1, the at least two contact portions 6 are sequentially arranged along the extending direction of the contact section 3313. The number of the at least two contact portions 6 may be 2 or more, and the intervals between two adjacent contact portions 6 may be equal or unequal. In this embodiment, the connecting assembly 33 is overlapped with the rotation center of the rotating member 31 and is located at the center of the rotating member 31, so that the rotation tracks of the at least two contact portions 6 are circular tracks or arc tracks with the center of the rotating member 31 as the center. Correspondingly, as shown in fig. 4 and 5, in order to ensure that the at least two contact portions 6 can make electrical contact with the at least two contacts 23 on the control board 2, the at least two contacts 23 are distributed at intervals on the control board 2 to form circular arc or circular ring regions. In practical applications, the at least two contact members 23 may be circular, fan-shaped, quadrilateral, or other shapes. The locus of rotation of the at least two contact portions 6 is within the area formed by the at least two contact members 23.

In the present embodiment, as shown in fig. 5, the at least two contact pieces 23 are exposed on the surface of the control board 2 facing the rotating component 31 for the at least two contact portions 6 to electrically contact. The contact 23 is made of a conductive material, for example, a metal foil. The at least two contact members 23 are electrically connected to the control board 2, and when each contact member 23 is electrically connected to at least one of the at least two contact portions 6, the resistance values of the contact members 23 are different. For example, the at least two contacts 23 include a contact a, a contact B, and a contact C, and the at least two contact portions 6 include a contact portion a and a contact portion B. When the contact piece A is in electric contact with the contact part a, a circuit on the control board 2 is conducted, and at the moment, the resistance value on the circuit is m omega, namely the resistance value corresponding to the contact piece A is m omega; when the contact part B is electrically contacted with the contact part a and the contact part B at the same time, the circuit on the control board 2 is conducted, and at this time, the resistance value on the circuit is n Ω, that is, the resistance value corresponding to the contact 23 is n Ω; similarly, the resistance value corresponding to the contact C is p Ω. Wherein m, n and p are all different, so the power of the electronic cigarette is adjusted by changing the resistance value in the regulating loop. In this way, the rotating member 31 drives the at least two contact portions 6 to establish electrical connection with different contact members 23 on the control board 2 during rotation, so as to achieve the purpose of adjusting the power of the electronic cigarette.

In an embodiment of the present invention, since the interval between the at least two contact portions 6 is fixed, in order to increase the area of the contact area between the contact portions 6 and the contact members 23, the contact stability is improved, and each contact member 23 is divided into a plurality of parts. Referring to fig. 4, preferably, each of the at least two contact members 23 includes a first contact member 231 and a second contact member 232, and the first contact member 231 and the second contact member 232 are spaced apart from each other. The first contact 231 and the second contact 232 are arranged in parallel, that is, when any one of the first contacts 231 is electrically contacted with the at least two contacts 23, the corresponding contact 23 can be electrically connected with the at least two contact portions 6. Thus, even if one of the first contact 231 and the second contact 232 fails or is damaged and cannot be electrically connected with at least two contact portions 6, the other contact can be normally used, so that the fault tolerance of the control board 2 is improved, and the stability of electrical contact is improved. Preferably, the at least two contact portions 6 include a first contact portion 61 and a second contact portion 62, wherein the first contact portion 61 corresponds to the first contact 231, and the second contact portion 62 corresponds to the second contact 232. That is, the first contact portion 61 may be electrically connected to the first contact 231, and the second contact portion 62 may be electrically connected to the second contact 232.

Further, the first contact member 231 and the second contact member 232 are both in a fan shape, and are concentrically disposed. That is, the center lines of the first contact 231 and the second contact 232 are overlapped and pass through the center of the circular arc or the circular ring surrounded by the contacts 23. The first contact 231 and the second contact 232 each include a top arc 2311 and a bottom arc 2312, wherein the top arc 2311 of the first contact 231 has a length greater than the top arc 2311 of the second contact 232. Preferably, the top arcs 2311 of the first contacts 231 are located on the same top circle, and the bottom arcs 2312 of the first contacts 231 are located on the same bottom circle. Meanwhile, the top arcs 2311 of the second contacts 232 are located on the same top circle, and the bottom arcs 2312 of the second contacts 232 are located on the same bottom circle. This allows the first contact members 231 to define a first circular arc region or a first annular region, and the second contact members 232 to define a second circular arc region or a second annular region. Correspondingly, the rotation track of the first contact part 61 is in the first arc area or the first ring area, so as to maximize the contactable area of the first contact part 61, thereby ensuring stable electrical connection. Meanwhile, the rotation locus of the second contact portion 62 is in the second arc region or the second circular ring region to maximize the area that the second contact portion 62 can contact, thereby ensuring stable electrical connection.

In this embodiment, as shown in fig. 2, the knob 32 is connected to an end of the rotating member 31 away from the control board 2, and partially extends out of the mounting hole 11 for user operation. The knob 32 includes a bottom plate 322 and a side wall 321 formed by bending an edge of the bottom plate 322 toward the rotation member 31. The side wall 321 is sleeved on the periphery of the mounting base 1, the chassis 322 is attached to the end face of the mounting hole 11 deviating from the control panel 2, and the chassis 322 is fixedly connected with the rotating part 31. When the side wall 321 is rotated by an external force, the side wall 321 drives the base plate 322 to rotate, so that the rotating member 31 is driven by the base plate 322 to rotate relative to the mounting base 1 and the control panel 2.

Further, referring to fig. 1 and fig. 2, the power adjusting device further includes an elastic limiting member 7, one end of the elastic limiting member 7 is received in the rotating member 31 and connected to the rotating member 31, and the other end of the elastic limiting member 7 extends out from the radial direction of the rotating member 31 and elastically abuts against the inner wall of the mounting hole 11. When the rotating member 31 rotates in the mounting hole 11, the elastic limiting member 7 slides along the inner wall of the mounting hole 11. In practical applications, the elastic limiting member 7 may include a spring 71 and a ball 72, the spring 71 is connected to the rotating member 31 and is received in the rotating member 31, and the ball 72 is partially received in the spring 71 and partially extends out of the spring 71 and abuts against the inner wall of the mounting hole 11. When the rotating member 31 rotates, the ball 72 is driven to rotate, and meanwhile, the ball 72 also rolls relative to the spring 71 and the inner wall of the mounting hole 11, which is beneficial to reducing the rotation resistance of the rotating member 31, so that the rotating member 31 can rotate smoothly in the mounting groove.

Further, the inner wall of the mounting hole 11 is provided with at least two limiting grooves 14, and the positions of the at least two limiting grooves 14 correspond to the positions of the at least two contact members 23. One limiting groove 14 corresponds to one contact piece 23, and one contact piece 23 corresponds to one power value. Meanwhile, the at least two limiting grooves 14 are matched with the ball 72. When the rotating member 31 is rotated by the knob 32, the rotating member 31 drives the at least two contact portions 6 to rotate and electrically contact one of the contact members 23. At this time, the ball 72 is partially snapped into one of the retaining grooves 14 to achieve the retaining, so that the elastic contact piece 23 is kept in the state of being electrically connected with one of the contact pieces 23, and the power of the electronic cigarette is kept at the power value corresponding to the contact piece 23. When the knob 32 is further rotated, the at least two contact portions are in electrical contact with the other contact member 23, and at the same time, the ball 72 is caught from the one retaining groove 14 into the other retaining groove 14 adjacent thereto, and rattles. Therefore, a user can know whether the adjustment is in place or not through the adjustment sound, and meanwhile, the adjustment hand feeling is enhanced through the matching between the elastic limiting piece 7 and the limiting groove 14.

In the present embodiment, as shown in fig. 1, in order to further enhance the feel of the user's adjustment knob 32, the power adjustment device further includes at least one damping member 4 for increasing the rotational resistance between the rotating mechanism 3 and the mounting base 1. Preferably, the damping member 4 is made of soft rubber, such as a silicone ring or a rubber ring. The damping piece 4 is arranged between the rotating mechanism 3 and the mounting seat 1. Specifically, a clearance groove adapted to the damping element 4 may be disposed on one of the chassis 322 of the knob 32 or the mounting base 1, and a part of the damping element 4 is accommodated in the clearance groove and elastically abuts against the chassis 322 and the mounting base 1, respectively. When the knob 32 is forced to rotate, the damping member 4 is pressed by the mounting base 1 and the bottom plate 322, thereby increasing the friction force therebetween. Further, a damping member 4 may be disposed between the mounting base 1 and the rotating member 31, so that the damping member 4 elastically abuts against the mounting base 1 and the rotating member 31, respectively, to increase the rotational resistance between the mounting base 1 and the rotating member 31.

In this embodiment, as shown in fig. 1, the power adjusting device further includes a scale ring 5. The scale ring 5 is sleeved on the mounting seat 1 and is fixedly connected with the mounting seat 1. In practical application, the scale ring 5 can be in interference fit with the mounting seat 1 to form a fixed connection; it is also possible to fasten the scale ring 5 to the mounting 1 by means of a coupling. The knob 32 is sleeved on the periphery of the scale ring 5, that is, the scale ring 5 is located between the mounting seat 1 and the knob 32. Since the scale ring 5 is tightly connected to the mounting base 1, the knob 32 is rotatably connected to the mounting base 1, and thus when the knob 32 is rotated, the knob 32 is also rotated with respect to the scale ring 5. Further, at least two scales 51 are arranged on the scale ring 5, and the at least two scales 51 correspond to the at least two contact members 23 one to one. For example, the at least contact 23 comprises contact a, contact B and contact C, then the at least two scale rings 5 comprise scale a, scale B and scale C. The contact piece A corresponds to the scale a, the contact piece B corresponds to the scale B, and the contact piece C corresponds to the scale C. The at least two scale rings 5 enclose an arc or a circular arc corresponding to the at least two contact members 23.

In an embodiment of the present invention, as shown in fig. 5, the at least two contact members 23 enclose a circular ring-shaped region, and correspondingly, the scales 51 on the knob 32 are distributed at equal intervals and enclose a whole circle. The at least two contact portions 6 can be rotated 360 degrees along the control panel 2 by the rotating member 31, so that the user can directly rotate from the first scale to the last scale without sequentially rotating from the first scale to the second scale and the third scale … … until the last scale when adjusting the knob 32. Therefore, the times of adjusting the knob 32 by the user are reduced, the adjusting efficiency is improved, the time of the user is saved, and the convenience is brought to the use of the user.

In an embodiment of the present invention, as shown in fig. 4, the at least two contact members 23 define a circular arc region. Correspondingly, at least two scales 51 on the knob 32 also enclose an arc. That is, the rotation stroke of the knob 32 with respect to the mounting base 1 is only the arc interval surrounded by the at least two scales 51. Therefore, the rotating mechanism 3 is further provided with a limiting column 3221. Specifically, the position-limiting column 3221 is convexly disposed on one side of the knob 32 facing the mounting seat 1. Correspondingly, the mounting base 1 is provided with an arc-shaped limiting groove 15 corresponding to the arc, and the limiting post 3221 is arranged in the arc-shaped limiting groove 15. When the knob 32 is forced to rotate, the limiting posts 3221 rotate along the circular arc-shaped limiting grooves 15. When the knob 32 is rotated to indicate the first scale 51, the limiting column 3221 abuts against one end of the circular arc-shaped limiting groove 15; when the knob 32 is rotated to indicate the last scale 51, the limiting column 3221 abuts against the other end of the circular arc-shaped limiting groove 15. In this embodiment, the rotation stroke of the knob 32 can be limited by the matching between the limiting posts 3221 and the arc-shaped limiting grooves 15, and the knob 32 can also play a role in guiding in the rotation process, so as to prevent the radial displacement between the knob 32 and the base.

Preferably, a first stopper 13 may be provided in the mount 1, and a second stopper 52 adapted to the first stopper 13 may be provided in the scale ring 5. When the scale ring 5 is sleeved on the mounting seat 1, the first limiting portion 13 and the second limiting portion 52 are matched to position the scale ring 5 and the mounting seat 1. Since the mounting base 1 and the control panel 2 are positioned by the positioning columns 12 and the positioning holes 21, and the positional relationship between the two is uniquely determined, the position between the scale ring 5 and the control panel 2 can be uniquely determined by the cooperation between the first position-limiting part 13 and the second position-limiting part 52. So that the position between the at least two scales 51 and the at least two contact members 23 can be uniquely determined, and the at least two scales 51 correspond to the at least two contact members 23 one to one. The positioning method adopted by the embodiment is convenient to assemble and accurate in positioning.

When at least two contact portions 6 on the connecting assembly 33 are rotated to electrically contact with a contact member 23, the knob 32 indicates the corresponding scale 51 of the contact member 23. In practical applications, a window 3211 for exposing the scale 51 may be formed in the knob 32, and when the at least two contact portions 6 are electrically contacted with the contact a, the knob 32 rotates to expose the scale a to the window 3211, so as to indicate the scale a. Of course, it is also possible to provide an indication arrow on the knob 32, and notify the user of the scale 51 corresponding to the current contact piece 23 by pointing the indication arrow to each scale 51. In practical applications, the scale 51 refers to the operating power value of the electronic cigarette.
