Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of electronic smoking set, and particularly relates to a smoking set for heating cigarettes. BACKGROUND

[0002] The heat-not-burn tobacco product is to heat tobacco by using an external heat source instead of igniting tobacco to generate tobacco flavor gas, and has carbon heating, electric heating and the like. Different from traditional cigarettes, the low-temperature cigarette designed with the idea of "heat-not-burn" can heat tobacco to a proper degree to emit flavor, without igniting tobacco. Generally, the high temperature of 350 DEG C to 600 DEG C in the process of smoking ordinary cigarettes can generate many harmful substances, while the low-temperature cigarette is below 300 DEG C, and the harmful substances are reduced. Here, "low temperature" refers to relative to the traditional burning cigarette.

[0003] In the process of smoking the low-temperature non-combustion cigarette, an external heating device, i.e. the heat-not-burn smoking set, is needed.

[0004] Chinese patent (CN107890141A) discloses a heat-not-burn smoking set with an extractor, which is characterized by comprising a rotating shell, an extractor and a heating device with a heating cavity. The extractor has a relative first end and a second end, the first end is installed in the heating cavity of the heating device, the second end is provided with an insertion cavity for inserting a smoking article, and a spiral guide groove is arranged on the outer peripheral wall of the second end. The rotating shell is hollowly arranged, one end is sleeved on the heating device, and the other end is provided with a clamping assembly which is in sliding cooperation with the spiral guide groove. A strip-shaped guide rail is arranged on the inner wall of the heating cavity along the direction from the bottom to the cavity opening. A strip-shaped guide groove is arranged on the outer peripheral wall of the first end in sliding cooperation with the strip-shaped guide rail, so as to rotate the extractor into / out of the heating cavity. The rotation of the extractor relative to the heating sheet drives the cigarette to rotate and come out of the heating sheet, so as to avoid the problem that the tobacco end of the smoking article after smoking is easily adhered to the heating cavity of the non-combustion electronic smoking set and is not easy to pull out.

[0005] However, in the actual use process, the extractor does not clamp the smoking cigarette, and when the cigarette is pulled out through the extractor, the tobacco of the cigarette is easily adhered to the heating sheet, which affects the next use of the smoking set. SUMMARY

[0006] The purpose of the present application is to provide a smoking set for heating cigarettes, which solves the problem that the tobacco of the cigarette is easily adhered to the heating sheet, which affects the next use of the smoking set, caused by the structural defects of the existing smoking set.

[0007] To achieve the above technical purpose, the technical scheme adopted by the present application is as follows:

[0008] A heating cigarette smoking set comprises a main body, a heating mechanism and a lifting cylinder, the main body is fixedly connected with a connecting cylinder, the heating mechanism is installed on the main body and located in the connecting cylinder, a heating rod is fixedly installed on the heating mechanism, the lifting cylinder is arranged in the connecting cylinder and sleeved on the heating mechanism, an annular support table is integrally formed on the inner wall of the lifting cylinder above the heating mechanism and sleeved on the heating rod, a vertical sliding groove and a spiral sliding groove are formed in the inner wall of the connecting cylinder, the lower end of the vertical sliding groove is communicated with the top end of the spiral sliding groove, a sliding column is fixedly installed on the outer wall of the lifting cylinder, the sliding column is located in the vertical sliding groove, a limiting table is fixedly arranged on the upper end of the lifting cylinder above the connecting cylinder, a bearing is installed on the lifting cylinder above the limiting table, an installation ring is installed on the lifting cylinder above the bearing, a pushing sleeve is slidingly installed on the connecting cylinder, a connecting seat is fixedly arranged on the connecting cylinder above the pushing sleeve, the connecting seat is fixedly connected with the outer ring of the bearing, two half rings are slidingly installed on the installation ring, the two ends of each half ring are inclined slopes gradually inclined inward from top to bottom, two side rods are fixedly installed on the outer side of the connecting seat on the main body, a pressing rod is fixedly arranged on the upper end of the side rod, the two sides of the pressing rod are inclined slopes gradually inclined inward from top to bottom, the pressing rod is located between the two half rings, and an elastic extrusion mechanism is installed on the installation ring outside the half ring.

[0009] Further limitation, a plurality of dovetail blocks are fixedly installed on the installation ring, dovetail grooves are formed in the half rings, and the half rings are slidingly installed on the installation ring through the cooperation of the dovetail grooves and the dovetail blocks. Such a structure design is simple in structure and convenient to use.

[0010] Further limitation, the elastic extrusion mechanism comprises four first compression springs and four fixed blocks, one mounting block is integrally formed at each end of the half ring, a blind hole is formed in the outer end face of the mounting block, the fixed blocks are installed on the installation ring and located outside the mounting blocks, and the first compression springs are located in the blind holes. Such a structure design, through the four first compression springs and the four fixed blocks, the elastic extrusion mechanism is formed, and the elastic pushing of the two half rings is completed, so as to form clamping of the cigarette.

[0017] 1. Through the cooperation between the lifting cylinder, the sliding column, the bearing, the spiral sliding groove, the two half rings and the elastic extrusion mechanism, the lifting cylinder rotates while ascending, thereby driving the cigarettes fixed by the two half rings to rotate relative to the heating rod, and the tobacco material adhered to the heating rod is caused to fall off by utilizing the friction between the cigarettes and the heating rod.

[0018] 2. Through the cooperation between the two half rings and the pressing rod, when the push sleeve is pushed to a certain height, the pressing rod is clamped between the two half rings, so that the two half rings move to both sides to overcome the prestress of the first compression spring, thereby causing the middle part of the mounting ring and the lifting cylinder to be completely exposed, facilitating the placement of the cigarettes, and also loosening the clamping of the cigarettes, thereby facilitating the pulling out of the cigarettes.

[0019] 3. Through the cooperation between the half ring, the sliding column, the vertical sliding groove and the first compression spring, the half ring can move inward under the action of the elastic extrusion mechanism in the middle and late period of the descending process and in the early and middle period of the ascending process, thereby clamping the cigarettes.

[0020] 4. The lifting cylinder and the push sleeve are connected through the bearing, and the push sleeve can be prevented from rotating in the rotating process of the lifting cylinder through the cooperation between the stop block and the positioning groove. BRIEF DESCRIPTION OF DRAWINGS
