Next, with reference to the drawings, a tobacco rod assembly 100 for an electronic cigarette 1000 according to an embodiment of the present invention is described.

As shown in fig. 1, the tobacco rod assembly 100 includes: cigarette rod casing 1 and circuit board 2 are formed with installation cavity 11 in the cigarette rod casing 1, and circuit board 2 is located in installation cavity 11. Therefore, the circuit board 2 can be protected by the cigarette rod shell 1, and the working reliability and the service life of the circuit board 2 are improved. It should be noted that the material of the cigarette rod housing 1 is not limited, and may be, for example, a metal material, or a non-metal material, and for example, in some embodiments, the cigarette rod housing 1 may be an aluminum housing or a plastic housing.

Therefore, the cigarette rod assembly 100 can be electrically connected with the accessories, such as a cartridge, of the electronic cigarette 1000, which are installed on the cigarette rod assembly 100, through the external connection part 32 exposed outside the installation cavity 11, so as to achieve the purposes of power supply or electric control of the cartridge.

As shown in fig. 1 and 2, the tobacco rod assembly 100 further comprises: the elastic conductive piece 4 is located in the installation cavity 11, the elastic conductive piece 4 is arranged on the circuit board 2 and electrically connected with the circuit board 2, the elastic conductive piece 4 elastically abuts against the inner connection part 31 to be electrically contacted and connected with the conductive needle 3, namely, the elastic conductive piece 4 is electrically contacted and connected with the inner connection part 31 of the conductive needle 3, so that the conductive needle 3 is electrically connected with the circuit board 2 through the missile-shaped conductive piece 4. Specifically, when the elastic conductive member 4 is electrically connected to the inner connection portion 31 of the conductive pin 3, the elastic conductive member 4 itself has elasticity, so that it can elastically deform to press the inner connection portion 31 of the conductive pin 3 under the reaction force provided by the circuit board 2, thereby achieving reliable electrical contact connection between the elastic conductive member 4 and the inner connection portion 31 of the conductive pin 3, and ensuring the reliability of electrical connection between the conductive pin 3 and the circuit board 2.

However, according to the cigarette rod assembly 100 of the embodiment of the present invention, the elastic conductive member 4 is disposed on the circuit board 2, and the elastic conductive member 4 is electrically connected to the inner connecting portion 31 of the conductive pin 3, so as to replace the method of welding the conductive wire to connect the circuit board 2 and the conductive pin 3, thereby simplifying the operation process, saving time and labor, and improving the reliability of electrical connection, and when the linked conductive pin 3 is used, the problem of being stuck by the winding of the conductive wire can be avoided, and the conductive wire can be prevented from being stacked and disordered inside the cigarette rod assembly 100, thereby improving the working reliability of the cigarette rod assembly 100, and reducing the volume of the cigarette rod assembly 100 to a certain extent.

In some embodiments of the present invention, as shown in fig. 2-3, the elastic conductive member 4 may comprise: the spring structure 41, the spring structure 41 may include an electrical contact 411, a thickness outer side surface of the electrical contact 411 has a contact region 4110, and the electrical contact 411 is electrically connected to the inner portion 31 through the contact region 4110. That is, at least a part of the thickness outside surface of the electric contact piece 411 is provided toward the inner portion 31 of the conductive pin 3, and elastically abuts against the inner portion 31 of the conductive pin 3 to realize electric contact connection of the electric contact piece 411 and the inner portion 31.

Therefore, the elastic conductive piece 4 comprises the elastic sheet structure 41, so that the structure of the elastic conductive piece 4 can be simplified, the cost of the elastic conductive piece 4 is reduced, the thickness outer side surface of the elastic sheet structure 41 is abutted with the inner connection part 31 of the conductive pin 3, the electric contact connection area between the elastic sheet structure and the conductive pin can be increased as much as possible, and the reliability of electric conduction between the elastic sheet structure and the conductive pin is improved to a certain extent.

In some embodiments of the present invention, as shown in fig. 2 to 4, the electrical contact 411 is formed in a bent shape, a bent portion of the electrical contact 411 protrudes toward the inner connection portion 31, and the contact region 4110 is formed at the bent portion. Thus, by abutting the bent portion of the electric contact piece 411 against the inner portion 31 of the conductive pin 3, the structural strength of the contact region 4110 of the electric contact piece 411 can be increased as much as possible, and the reliability of the electric contact connection between the electric contact piece 411 and the inner portion 31 of the conductive pin 3 can be further improved.

Note that the electrical contact 411 may be formed in a single-bent shape, such as a V-shape or a U-shape, the electrical contact 411 may be formed in a multi-bent shape, such as an M-shape, or the like. For example, as shown in fig. 2 and 4, when the electrical contact 411 is formed in a single-bend shape, the electrical contact may include a first segment 4111 and a second segment 4112 intersecting at a non-zero included angle, one end of the first segment 4111 and one end of the second segment 4112 are smoothly transited by a third segment 4113, the third segment 4113 is a bend of the electrical contact 411, and the contact region 4110 is formed on the third segment 4113.

In some embodiments of the present invention, as shown in fig. 4-5, the thickness outer side surface at the bend has a thickened portion 4114, and the thickened portion 4114 is formed as a contact area 4110. From this, can further improve the structural strength of the contact region 4110 of electric contact piece 411, further improve the reliability that electric contact piece 411 is connected with the inner contact portion 31 electricity of conducting pin 3, and avoid electric contact piece 411 whole thick, lead to the problem that elasticity receives the influence, thereby make shell fragment structure 41 can have better elasticity, make contact region 4110 can with the reliable butt of the inner contact portion 31 of conducting pin 3, further improve the reliability that electric contact piece 411 is connected with the inner contact portion 31 electricity of conducting pin 3.

In some embodiments of the present invention, as shown in fig. 2 to 4, the spring structure 41 further includes a support piece 412, the support piece 412 is connected to the electrical contact piece 411, and the support piece 412 is supported on a side of the electrical contact piece 411 away from the inner portion 31. Therefore, the supporting piece 412 is arranged to support the electric contact piece 411, so that the elastic supporting force borne by the electric contact piece 411 can be improved, the electric contact piece 411 can be reliably abutted against the inner contact part 31 of the conductive pin 3, and the reliability of the electric contact connection between the electric contact piece 411 and the inner contact part 31 of the conductive pin 3 is further improved.

In some alternative examples, as shown in fig. 2 to 4, the support plate 412 extends along a length thereof with a first end 4121 and a second end 4122 at two ends, respectively, the first end 4121 is located at a side of the second end 4122 away from the circuit board 2 and connected to the electrical contact 411 in a thickness direction of the circuit board 2, and the contact area 4110 is located between the first end 4121 and the second end 4122. That is, the distance from the first end 4121 to the perpendicular line of the circuit board 2 is L1, the distance from the second end 4122 to the perpendicular line of the circuit board 2 is L2, the maximum distance from the contact area 4110 to the perpendicular line of the circuit board 2 is L3, and L1 > L3 > L2. However, it should be noted that the centers of the first end 4121, the second end 4122 and the contact area 4110 are not required to be located in the same plane perpendicular to the circuit board 2. Therefore, the support piece 412 can form elastic support for the electric contact piece 411 in the direction perpendicular to the circuit board 2, so as to further improve the elastic support force applied to the electric contact piece 411, so that the electric contact piece 411 can be reliably abutted against the inner portion 31 of the conductive pin 3, and further improve the reliability of the electric contact connection between the electric contact piece 411 and the inner portion 31 of the conductive pin 3.

In some alternative examples, as shown in fig. 2 to 4, the support plate 412 includes a protrusion 4123 partially protruding toward a direction close to the inner portion 31, and it should be noted that the protruding direction is to be broadly understood and is not required to be protruding toward the inner portion 31 as long as the protrusion 4123 is close to the inner portion 31 with respect to other portions of the support plate 412. In the thickness direction of the circuit board 2, the protruding portion 4123 is located between the contact region 4110 and the second end 4122. That is, the perpendicular distance from the second end 4122 to the circuit board 2 is L2, the maximum perpendicular distance from the contact area 4110 to the circuit board 2 is L3, the maximum perpendicular distance from the protruding portion 4123 to the circuit board 2 is L4, and L3 > L4 > L2. However, it should be noted that the center of the protruding portion 4123, the center of the second end 4122 and the center of the contact area 4110 are not required to be located in the same plane perpendicular to the circuit board 2, and the center of the protruding portion 4123 and the center of the contact area 4110 are not required to be located in the same plane parallel to the circuit board 2. Therefore, the shape of the supporting piece 412 can provide better elastic supporting force for the electric contact piece 411, so that the electric contact piece 411 can be reliably abutted against the inner connection part 31 of the conductive pin 3, the reliability of the electric contact connection between the electric contact piece 411 and the inner connection part 31 of the conductive pin 3 is further improved, and the stress borne by the elastic piece structure 41 can be better dispersed by the shape of the supporting piece 412 and the relative position relationship between the supporting piece 412 and the electric contact piece 411, so that the service life of the elastic piece structure 41 is prolonged.

In some alternative examples, as shown in fig. 2-4, the resilient sheet structure 41 further includes a flat sheet 413, the flat sheet 413 is connected to the second end 4122 of the supporting sheet 412, the electrical contact piece 411, the supporting sheet 412, and the flat sheet 413 are all disposed on the same side of the thickness of the circuit board 2, and the side surface of the thickness of the flat sheet 413 is supported on the side surface of the thickness of the circuit board 2. From this, can improve the support reliability of circuit board 2 to shell fragment structure 41 to provide reliable and sufficient reaction force for shell fragment structure 41 by circuit board 2, improve the reliability that electric contact piece 411 and conductive pin 3's inner contact 31 electricity contact are connected, and can disperse the stress that shell fragment structure 41 receives better, thereby improve shell fragment structure 41's life.

In some alternative examples, as shown in fig. 2-4, the circuit board 2 has a through hole 21, the spring structure 41 further includes an extending piece 414, one end of the flat piece 413 is connected to the second end 4122 of the supporting piece 412, and the other end of the flat piece 413 extends toward the direction close to the electrical contact 411 (as shown in fig. 4), or the other end of the flat piece 413 extends away from the electrical contact 411 (as shown in fig. 15), and the extending piece 414 is connected to the other end of the flat piece 413 and extends into the through hole 21. Therefore, the matching of the through hole 21 and the extending piece 414 can be utilized to play a role of assembling and pre-positioning the elastic sheet structure 41 and the circuit board 2, so that the connection efficiency of the elastic sheet structure 41 and the circuit board 2 is improved, the problem of relative dislocation when the elastic sheet structure and the circuit board are connected is improved, and the connection reliability, effectiveness and stability of the elastic sheet structure 41 and the circuit board 2 can be improved.

Alternatively, in some embodiments, the elastic conductive member 4 may be a surface mount device disposed on the circuit board 2. That is, the elastic conductive member 4 may be connected to the circuit board 2 in a surface mount manner. Therefore, the connection difficulty of the elastic conductive piece 4 and the circuit board 2 can be simplified, the connection efficiency of the elastic conductive piece 4 and the circuit board 2 is improved, and the electric connection reliability of the elastic conductive piece 4 and the circuit board 2 is improved. Therefore, in some embodiments of the present invention, the elastic conductive member 4 is directly attached to the surface of the circuit board 2, and the elastic conductive member 4 is directly abutted against the conductive pin 3, so that indirect electrical connection between the circuit board 2 and the conductive pin 3 can be reliably and effectively achieved, instead of connecting the conductive pin 3 and the circuit board 2 by means of conductive wire welding. For example, when the leaf structure 41 includes the flat plate 413, and the thickness side surface of the flat plate 413 is supported on the thickness side surface of the circuit board 2, the flat plate 413 may be used for surface mounting with the circuit board 2.

Alternatively, the spring structure 41 is formed in a bent shape of an elongated sheet body with a length greater than a width, that is, the spring structure 41 is formed by bending an elongated sheet body that can be flattened to have a length greater than a width. Therefore, the structure can be simplified, the processing is convenient, and the elastic sheet structure 41 can be ensured to have better elasticity and structural reliability. For example, in the example shown in fig. 4, when the leaf spring structure 41 includes: when the electrical contact piece 411, the supporting piece 412, the flat piece 413 and the extending piece 414 are connected, the electrical contact piece 411, the supporting piece 412, the flat piece 413 and the extending piece 414 are connected in sequence along the length direction of the elastic piece structure 41. For another example, in the example shown in fig. 15, when the leaf spring structure 41 includes: when the electrical contact 411, the supporting piece 412 and the plate piece 413 are used, the electrical contact 411, the supporting piece 412 and the plate piece 413 are connected in sequence along the length direction of the spring structure 41.

In some embodiments, as shown in fig. 5-11, the elastic conductive member 4 further comprises: the housing structure 42, the housing structure 42 includes two side plate portions 421, and the two side plate portions 421 are spaced apart from each other and disposed on two sides of the width of the elastic sheet structure 41. Therefore, the two side plate parts 421 can be used to protect the elastic sheet structure 41, so that the problem that the elastic sheet structure 41 is deformed by external force and cannot be reliably electrically connected with the conductive pin 3 in the assembling process is solved.

Further, as shown in fig. 4 to 11, the housing structure 42 may further include a top plate portion 422, the top plate portion 422 is disposed between the two side plate portions 421 and connected to at least one of the side plate portions 421, and the top plate portion 422 is located on a side of the elastic sheet structure 41 away from the circuit board 2 and is parallel to the circuit board 2. Therefore, the elastic sheet structure 41 can be further protected by the top plate part 422, and the problem that the elastic sheet structure 41 is deformed by external force and cannot be reliably electrically connected with the conductive pin 3 in the assembling process is further solved. In addition, when the elastic conductive member 4 is connected to the circuit board 2 by surface mounting, the top plate 422 parallel to the circuit board 2 may also be used to clamp the elastic conductive member 4, for example, a suction device, such as a vacuum chuck, may be used to suck the elastic conductive member 4 so as to move the elastic conductive member 4 to a position where the surface mounting is required.
