[0029] As shown in Figure 1 , the present application provides a heating smoking set suitable for heating cigarettes of different lengths, which comprises a smoking set body 10, a heating element 20, and a blocking mechanism. The smoking set body 10 is formed with a heating cavity 11, the heating element 20 is arranged in the heating cavity 11, and one end of the heating element 20 is fixed to the bottom wall of the heating cavity 11. The blocking mechanism comprises a blocking plate 31 and a hand-held part. The blocking plate 31 is sleeved on the heating element 20, the inner side wall of the blocking plate 31 abuts against the heating element 20, and the outer side wall abuts against the side wall of the heating cavity 11. The inner side wall of the blocking plate 31 is provided with a plating layer, and the resistance of the plating layer is less than the resistance of the surface of the heating element 20. The hand-held part is fixed to the blocking plate 31 to drive the blocking plate 31 to move along the side wall of the heating cavity 11.

[0030] At present, the heating smoking set is formed with a heating cavity 11, and the size of the heating cavity 11 is fixed, which can only match the heating cigarettes of a specific length specification, and there is a great limitation in use.

[0031] In the present application, the outer wall of the heating element 20 is coated with a conductive track along the axial direction thereof, and the conductive tracks are uniformly distributed. The top of the conductive track is led from the inside of the heating element 20 to the bottom of the heating element 20 through a connecting lead. The heating element 20 is fixed in the heating cavity 11 formed by the smoking set body 10. One end of the heating element 20 is fixed to the bottom of the heating cavity 11. The blocking plate 31 is sleeved on the heating element 20, i.e. the inner side wall of the blocking plate 31 abuts against the heating element 20. At the same time, the outer side wall of the blocking plate 31 abuts against the side wall of the heating cavity 11. Therefore, the blocking plate 31 can move along the side wall of the heating cavity 11 in the heating cavity 11. When the heating cigarettes of different length specifications are put into the heating cavity 11, the blocking plate 31 can be pushed to move along the heating cavity 11 to the bottom of the heating cavity 11, so that the part of the heating cigarette that needs to be heated is all loaded into the heating cavity 11. Specifically, referring to Figure 3 , the cross section of the blocking plate 31 is in the shape of a circular ring.

[0032] In addition, the inner side wall of the baffle 31 is plated, and the resistance of the plating layer is less than that of the conductive track on the surface of the heating element 20. For example, the conductive track on the surface of the heating element 20 is a copper plating layer, and the plating layer on the inner side wall of the baffle 31 can be a silver plating layer. Other commonly used plating layers are also applicable. Since the plating layer on the inner side wall of the baffle 31 has a small resistance, it is in conductive connection with the plating layer on the surface of the heating element 20 above the baffle 31, and the plating layer on the surface of the heating element 20 below the baffle 31 is short-circuited, thereby changing the resistance value of the heating element 20 and the heating area, so that the heating element 20 can concentrate on heating the placed length of the heated cigarette, and the heating efficiency is improved.

[0033] In the embodiment of the present application, the handheld part is fixed on the baffle 31, which can be fixed on the upper end face or the side face of the baffle 31 for convenient operation. When the heated cigarette is placed into the heating cavity 11, the cigarette can be pushed along the side wall of the heating cavity 11 by external force, and at this time the baffle 31 moves together with the heated cigarette. The baffle 31 can also be moved to the bottom of the heating cavity 11 by the handheld part, thereby leaving a space for the heated cigarette. In addition, after smoking is finished, the baffle 31 and the heated cigarette can be moved out of the heating cavity 11 by moving the handheld part to the top of the heating cavity 11.

[0034] The heating device for different length heated cigarettes provided by the embodiment of the present application is provided with a baffle mechanism in the heating cavity 11, the baffle 31 is sleeved on the heating element 20, and a plating layer is arranged on the inner side wall in contact with the heating element 20, and the resistance of the plating layer is less than that of the surface of the heating element 20; the outer side wall of the baffle 31 is in contact with the side wall of the heating cavity 11, so that the baffle 31 can move along the inner side wall of the heating cavity 11, thereby being able to place heated cigarettes of different length specifications; and the plating layer on the inner side wall of the baffle 31 is in conductive connection with the conductive track on the surface of the heating element 20 above the baffle 31. Since the plating layer on the inner side wall of the baffle 31 has a small resistance, the part of the heating element 20 below the baffle 31 is short-circuited, thereby changing the resistance value of the heating element 20, so that the position of the baffle 31 in the heating cavity 11 can be adjusted according to the different length of the heated cigarette, the heating height of the heating element 20 is changed, the heating element 20 can concentrate on heating the heated cigarette of different length, and the heating efficiency is improved.

[0035] In some embodiments, the handheld part is fixed on the outer side wall of the baffle 31; a sliding groove 12 penetrating through the heating device body 10 in the thickness direction is formed on the side wall of the heating cavity 11, and the sliding groove 12 extends along the axis direction of the heating device body 10; the handheld part extends out of the heating device body 10 through the sliding groove 12, and the handheld part moves along the sliding groove 12 to drive the baffle 31 to move along the side wall of the heating cavity 11.

[0036] In the embodiments of the present application, the handheld part is arranged on the side of the partition plate, and a sliding groove 12 is formed on the side wall of the heating cavity 11, the sliding groove 12 penetrates the thickness direction of the smoking set body 10, and the handheld part is extended out of the smoking set body 10 from the inside of the heating cavity 11 through the sliding groove 12. The sliding groove 12 extends along the axial direction of the smoking set body 10, and the handheld part can move up and down along the sliding groove 12 to drive the partition plate 31 to move along the inner wall of the heating cavity 11. The corresponding structure of the handheld part and the smoking set body 10 is arranged, which provides convenience for putting the heated cigarette into the heating cavity 11 and taking out the heated cigarette from the heating cavity 11, is simple to operate, and is suitable for the structure arrangement of the heating smoking set itself.

[0037] Further, the partition mechanism comprises a first elastic member (not shown in the figure), one end of the first elastic member is fixed on the bottom wall of the sliding groove 12, and the other end is fixed on the handheld part. That is to say, the first elastic member is installed between the bottom end of the sliding groove 12 and the handheld part, when the shortest specification of the heated cigarette is placed in the heating cavity 11, the first elastic member can be arranged in the original state; when other specifications of the heated cigarette are placed in the heating cavity 11, the partition plate 31 is moved to the bottom direction of the heating cavity 11 by pushing the handheld part downward, and the heated cigarette can completely enter the heating cavity 11, at this time, the first elastic member is in the compressed state. After the suction is finished, the external force applied to the handheld part is removed, and the elastic force of the first elastic member moves the partition plate 31 to the top direction of the heating cavity 11, so as to move the heated cigarette out of the heating cavity 11. The first elastic member can be a spring.

[0038] In other embodiments, the handheld part comprises a handle 32 and a shutter 33, the handle 32 is extended out of the smoking set body 10 through the sliding groove 12, and the shutter 33 is arranged on both ends of the handle 32 to cover the sliding groove 12. In the embodiments of the present application, referring to Figure 1 , Figure 2 , in order to ensure the heating effect in the heating cavity 11 and reduce the airflow circulation between the heating cavity 11 and the outside of the smoking set body 10, the shutter 33 is arranged on both ends of the handle 32 of the handheld part, and the shutter 33 is arranged corresponding to the sliding groove 12 on the smoking set body 10 to shield the sliding groove 12 and avoid the airflow circulation between the inside and outside of the heating cavity 11. The shutter 33 can be arranged on the outside of the smoking set body 10 or in the side wall of the smoking set body 10.

[0039] Further, the side wall of the smoking set body 10 is formed with a gap 13, and the shutter 33 is arranged in the gap 13 and extends along the direction of the sliding groove 12. Referring to Figure 1 , Figure 2 , the gap 13 formed in the side wall of the smoking set body 10 extends along the axial direction of the smoking set body 10, that is, the same as the extension direction of the sliding groove 12. The shutter 33 is fixed on the handle 32. The two shutters 33 on the upper end and the lower end of the handle 32 cover the sliding groove 12 respectively. The shutter 33 is arranged in the gap 13 formed in the side wall of the smoking set body 10, which is more conducive to shielding the airflow circulation.

[0040] In addition, the blocking mechanism comprises a second elastic member 34, one end of which is fixed to the bottom wall of the sliding groove 12 and the other end of which is fixed to the cover plate 33. Referring to Figure 1 、 Figure 2 When the cover plate 33 is arranged on the handle 32, the second elastic member 34 can be arranged between the cover plate 33 and the bottom wall of the sliding groove 12. Specifically, one end of the second elastic member 34 is fixed to the cover plate 33 at the lower end of the handle 32. The second elastic member 34 has the same effect as the first elastic member. After the external force applied to the handle 32 is removed, the elastic force of the second elastic member 34 moves the handle 32 and the blocking plate 31 towards the top of the heating cavity 11, thereby facilitating the removal of the heated cigarette from the heating cavity 11.

[0041] In some embodiments, the heating smoking set further comprises protective pads, the sliding groove 12 is covered with protective pads on both sides, and the two sides of the handle portion are respectively in abutment with the protective pads. In order to avoid the phenomenon that the sliding groove 12 on the side wall of the smoking set body 10 causes the outflow of hot air in the heating cavity 11 and makes the side wall of the smoking set body 10 scalding, and to avoid affecting the heating effect of the heating cavity 11, the sliding groove 12 is covered with protective pads on both sides; especially, the cooperation of the protective pads and the cover plate 33 can better reduce the outflow of air in the heating cavity 11 and ensure the heating effect of the heating cavity 11.

[0042] Further, the friction coefficient of the protective pad is greater than or equal to 0.5. By setting the friction coefficient of the protective pad in the above range, the sum of the friction force between the protective pad and the handle 32 and the gravity of the heated cigarette placed in the heating cavity 11 is greater than or equal to the elastic force of the first elastic member and the second elastic member 34, so that regardless of the length specification of the heated cigarette placed in the heating cavity 11, when the part that needs to be heated is completely placed in the heating cavity 11, the elastic member will not rebound after the external force applied to the handle 32 is removed, thereby ensuring that the heated cigarette is in the heating cavity 11 under the premise of not applying external force during smoking, which facilitates the use of the user. After smoking, the handle 32 and the blocking plate 31 can be moved towards the top of the heating cavity 11 by applying an external force to move the heated cigarette out.

[0043] The length of the tobacco segment of the heated cigarette is 12mm, 15mm or 16mm. When the heated cigarette with the maximum length is put into the heating cavity 11, the compression of the elastic member is less than the maximum compression of the elastic member. The rigidity coefficient of the elastic member is set to 1N / m. The part of the heated cigarette that needs to be heated is completely put into the heating cavity 11 by pressing the handle 32. According to the weight of the heated cigarette and the compression of the elastic member, the minimum friction coefficient of the protective pad can be calculated. The spring resilience force F=Kx=G+μf=(μ+1)G. The weight of a single cigarette is 1g. The compression of the spring is 16mm. The rigidity coefficient of the elastic member is set to 1N / m. The minimum friction coefficient of the protective pad is calculated to be 0.6.

[0044] In other embodiments, the material of the protective pad is silica gel or rubber. The distance between the silica gel on both sides of the chute 12 can be set to be less than the size of the handle 32. The handle 32 causes the silica gel on both sides to deform and increase the friction. Silica gel containing hard particles or methods such as engraving or sandblasting on the surface of the silica gel can be used to meet the needs of the minimum friction coefficient.

[0045] The above description of the disclosed embodiments enables those skilled in the art to carry out or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
