[0029] like Figure 1 As shown, the embodiment of the present application provides a heating smoking device suitable for heating cigarettes of different lengths, including a smoking device body 10, a heating element 20 and a baffle mechanism. The smoking device body 10 is formed with a heating chamber 11. The heating element 20 is arranged in the heating chamber 11, and one end thereof is fixed to the bottom wall of the heating chamber 11. The baffle mechanism includes a baffle plate 31 and a hand-held part. The baffle plate 31 is sleeved on the heating element 20, the inner side wall of the baffle plate 31 abuts against the heating element 20, and the outer side wall abuts against the side wall of the heating chamber 11; a coating is provided on the inner side wall of the baffle plate 31, and the resistance of the coating is less than the resistance of the surface of the heating element 20; the hand-held part is fixed on the baffle plate 31 to drive the baffle plate 31 to move along the side wall of the heating chamber 11.

[0030] A heating chamber 11 is formed in the current heating smoking device. The size of the heating chamber 11 is fixed and can only match heated cigarettes of a specific length specification, which has great limitations in use.

[0031] In the embodiment of the present application, a conductive track is coated on the outer wall of the heating element 20 along its axial direction, and the conductive track is evenly distributed, and 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 chamber 11 formed by the smoking device body 10. One end of the heating element 20 is fixed to the bottom of the heating chamber 11. The baffle plate 31 is sleeved on the heating element 20, that is, the inner wall of the baffle plate 31 abuts against the heating element 20. At the same time, the outer wall of the baffle plate 31 abuts against the side wall of the heating chamber 11. As a result, the baffle plate 31 can move along the side wall of the heating chamber 11 in the heating chamber 11. When heated cigarettes of different lengths are placed in the heating chamber 11, the baffle plate 31 can be pushed to move along the heating chamber 11 toward its bottom, so that the parts of the heated cigarettes that need to be heated are all loaded into the heating chamber 11. Specifically, refer to Figure 3 The cross section of the baffle plate 31 is circular.

[0032] In addition, a coating is formed on the inner wall of the baffle plate 31, and the resistance of the coating is less than the resistance of the conductive track on the surface of the heating element 20. For example, if the conductive track on the surface of the heating element 20 is a copper coating, the coating on the inner wall of the baffle plate 31 can be a silver coating. Other commonly used coatings are also applicable. Since the coating on the inner wall of the baffle plate 31 has a low resistance, it is conductively connected to the coating on the surface of the heating element 20 located above the baffle plate 31, so that the coating on the surface of the heating element 20 located below the baffle plate 31 is short-circuited, thereby changing the resistance value and heating area of ​​the heating element 20, so that the heating element 20 can concentrate on heating the placed heated cigarettes of a certain length, thereby improving the heating efficiency.

[0033] In the embodiment of the present application, the hand-held part is fixed on the baffle plate 31, and can be fixed on the upper end surface or side surface of the baffle plate 31 for easy operation. When the heated cigarette is placed in the heating chamber 11, the cigarette can be pushed along the side wall of the heating chamber 11 by external force, and the baffle plate 31 moves together with the heated cigarette. The baffle plate 31 can also be moved toward the bottom of the heating chamber 11 by the hand-held part, thereby leaving space for the heated cigarette to be placed. In addition, when the inhalation is finished, the baffle plate 31 and the heated cigarette can be driven out of the heating chamber 11 by moving the hand-held part toward the top of the heating chamber 11.

[0034] The embodiment of the present application provides a heating device for heating cigarettes of different lengths. A baffle mechanism is provided in the heating chamber 11. The baffle plate 31 is sleeved on the heating element 20, and a coating is provided on the inner wall abutting against the heating element 20. The resistance of the coating is less than the resistance of the surface of the heating element 20. The outer wall of the baffle plate 31 abuts against the side wall of the heating chamber 11, so that the baffle plate 31 can move along the inner wall of the heating chamber 11, so that heated cigarettes of different lengths can be placed. The coating on the inner wall of the baffle plate 31 is conductively connected to the conductive track on the surface of the heating element 20 located above the baffle plate 31. Since the coating on the inner wall of the baffle plate 31 has a low resistance, the part of the heating element 20 located below the baffle plate 31 is short-circuited, thereby changing the resistance value of the heating element 20. Therefore, the position of the baffle plate 31 in the heating chamber 11 can be adjusted according to the different lengths of the heated cigarettes, and the heating height of the heating element 20 is changed, so that the heating element 20 can concentrate on heating the heated cigarettes of different lengths, thereby improving the heating efficiency.

[0035] In some embodiments, the hand-held portion is fixed to the outer wall of the baffle plate 31; a slide groove 12 is formed on the side wall of the heating chamber 11 and penetrates the smoking device body 10 along the wall thickness direction, and the slide groove 12 extends along the axial direction of the smoking device body 10; the hand-held portion extends out of the smoking device body 10 from the slide groove 12, and the hand-held portion moves along the slide groove 12 to drive the baffle plate 31 to move along the side wall of the heating chamber 11.

[0036] In the embodiment of the present application, the hand-held part is arranged on the side of the baffle plate, and a slide groove 12 is formed on the side wall of the heating chamber 11, and the slide groove 12 runs through the thickness direction of the smoking device body 10, and the hand-held part extends out of the smoking device body 10 from the inside of the heating chamber 11 through the slide groove 12. The slide groove 12 extends along the axial direction of the smoking device body 10, and the hand-held part can move up and down along the slide groove 12, driving the baffle plate 31 to move along the inner wall of the heating chamber 11. The corresponding structural arrangement of the hand-held part and the smoking device body 10 provides convenience for putting heated cigarettes into the heating chamber 11 and taking them out of the heating chamber 11, and is simple to operate and suitable for the structural arrangement of the heating smoking device itself.

[0037] Furthermore, the barrier mechanism includes a first elastic member (not shown in the figure), one end of which is fixed to the bottom wall of the chute 12, and the other end is fixed to the handheld portion. That is to say, the first elastic member is installed between the bottom end of the chute 12 and the handheld portion, and when the shortest size of heated cigarettes is placed in the heating chamber 11, the first elastic member can be set to be in the original state; when other sizes of heated cigarettes are placed in the heating chamber 11, the handheld portion is pushed downward to move the barrier plate 31 toward the bottom of the heating chamber 11, and the heated cigarette can completely enter the heating chamber 11. At this time, the first elastic member is in a compressed state. After the inhalation is completed, the external force applied to the handheld portion is removed, and the elastic force of the first elastic member causes the barrier plate 31 to move toward the top of the heating chamber 11, thereby moving the heated cigarette out of the heating chamber 11. The first elastic member can be a spring.

[0038] In other embodiments, the hand-held portion includes a handle 32 and a shield 33. The handle 32 extends out of the smoking device body 10 from the slide slot 12. The shields 33 are provided at both the upper and lower ends of the handle 32 to cover the slide slot 12. Figure 1 , Figure 2 In order to ensure the heating effect in the heating chamber 11 and reduce the airflow between the heating chamber 11 and the outside of the smoking device body 10, shields 33 are respectively provided at the upper and lower ends of the handle 32 of the handheld portion. The shields 33 are provided corresponding to the slide grooves 12 on the smoking device body 10 to block the slide grooves 12 and prevent the airflow inside and outside the heating chamber 11. The shields 33 can be provided outside the smoking device body 10 or inside the side wall of the smoking device body 10.

[0039] Furthermore, a gap 13 is formed in the side wall of the smoking device body 10, and a shield 33 is disposed in the gap 13, and the shield 33 extends along the direction of the slide groove 12. Figure 1 , Figure 2 The gap 13 formed in the side wall of the smoking device body 10 extends along the axial direction of the smoking device body 10, that is, in the same direction as the extension of the slide 12. The shield 33 is fixed on the handle 32. The two shields 33 at the upper and lower ends of the handle 32 cover the slide 12 respectively. The shield 33 is arranged in the gap 13 formed in the side wall of the smoking device body 10, which is more conducive to blocking the airflow.

[0040] In addition, the barrier mechanism includes a second elastic member 34, one end of the second elastic member 34 is fixed to the bottom wall of the slide slot 12, and the other end is fixed to the shielding plate 33. Figure 1 , Figure 2 When the shield 33 is provided on the handle 32, a second elastic member 34 may be provided between the shield 33 and the bottom wall of the chute 12. Specifically, one end of the second elastic member 34 is fixed on the shield 33 at the lower end of the handle 32. The second elastic member 34 has the same function as the first elastic member. After the external force applied to the handle 32 is removed, the rebound force of the second elastic member 34 causes the handle 32 and the baffle 31 to move toward the top of the heating chamber 11, thereby facilitating the removal of the heated cigarette from the heating chamber 11.

[0041] In some embodiments, the heating smoking device further comprises a protective pad, both sides of the chute 12 are covered with the protective pad, and both sides of the hand-held portion are respectively in contact with the protective pad. In order to prevent the chute 12 on the side wall of the smoking device body 10 from causing the hot air flow in the heating chamber 11 to flow outward and causing the side wall of the smoking device body 10 to become hot, and to avoid affecting the heating effect of the heating chamber 11, both sides of the chute 12 are covered with a protective pad; in particular, the cooperation between the protective pad and the shield 33 can better reduce the outflow of the air flow in the heating chamber 11, and ensure the heating effect of the heating chamber 11.

[0042] Furthermore, the friction coefficient of the protective pad is greater than or equal to 0.5. The friction coefficient of the protective pad is set within the above range so that the sum of the friction between the protective pad and the handle 32 and the gravity of the heated cigarette placed in the heating chamber 11 is greater than or equal to the resilience of the first elastic member and the second elastic member 34. Therefore, no matter what length of heated cigarettes are placed in the heating chamber 11, when the part to be heated is completely placed in the heating chamber 11, the external force applied to the handle 32 is removed to ensure that the elastic member will not rebound, thereby ensuring that the heated cigarette is in the heating chamber 11 without applying external force during the smoking process, which is convenient for users to use. After the smoking is completed, the handle 32 and the baffle plate 31 can be moved toward the top of the heating chamber 11 by applying external force to remove the heated cigarette.

[0043] At present, the length specifications of the tobacco segments of heated cigarettes are 12mm, 15mm or 16mm. When the heated cigarette with the maximum length specification is placed in the heating chamber 11, the compression of the elastic member is less than the maximum compression of the elastic member. The stiffness coefficient of the elastic member is set to 1N / m, and the part of the heated cigarette to be heated is completely inserted into the heating chamber 11 by pressing the handle 32. According to the weight of the heated cigarette and the compression of the elastic member, the required minimum friction coefficient of the protective pad can be calculated. The spring rebound force F=Kx=G+μf=(μ+1)G, the weight of a single cigarette is 1g, the compression of the spring is 16mm, and the stiffness coefficient of the elastic member is set to 1N / m. The minimum friction coefficient of the protective pad can be calculated to be 0.6.

[0044] In other embodiments, the protective pad is made of silicone or rubber. The distance between the silicone on both sides of the slide 12 can be set to be smaller than the size of the handle 32, and the handle 32 causes the silicone on both sides to deform and increase friction. Silicone containing hard particles can also be used, or the surface of the silicone can be engraved or sandblasted to meet the above minimum friction coefficient requirements.

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