Description

Technical Field

[0001] The present invention belongs to the technical field of heated smoking articles, and in particular relates to a heated smoking article, a cigarette assembly and a use method thereof, which can assist in sealing a cigarette and exhausting air in the cigarette. Background Art

[0002] Many electric heating smoking systems have been proposed in the field of new heat-not-burn cigarettes. Using such electric heating smoking systems containing electric heaters to heat new heat-not-burn cigarettes can greatly reduce the harmful components produced by tobacco combustion in traditional cigarettes. However, the heating temperature provided by such electric heating smoking systems is much lower than the temperature at which traditional cigarettes burn. Compared with traditional cigarettes, the tobacco aroma components in the new cigarettes are difficult to be fully released, and the smoke volume is small. Therefore, such cigarettes are difficult to be accepted by traditional smokers.

[0003] One way to increase the release of aroma components is to increase the temperature of the heater appropriately, but a factor that limits the temperature of the heater is that too high a temperature may cause the tobacco material to smolder and also produce harmful gases. Considering the three elements of combustion, if the temperature of the heater is to be further increased on the current basis, the oxygen content in the air in which the tobacco material is located can be reduced.

[0004] One feasible solution is to seal the space where the tobacco material is located so that the airflow does not flow through the tobacco material during inhalation. However, if the cigarette end is sealed, the existing cigarette production line needs to be improved, which will greatly increase the production cost of the cigarette and limit the choice of heating devices, such as the inability to use a central heating element.

[0005] The present invention is proposed to solve the above-mentioned problems. Summary of the invention

[0038] The second aspect of the present invention provides a heating cigarette assembly that can assist in sealing a cigarette and exhausting air from the cigarette, comprising the heating cigarette device described in the first aspect and an oxygen-deficient heating cigarette 1;

[0039] The cigarette 1 comprises a tobacco segment 105 and an airflow one-way valve segment 104 which are coaxially abutted in sequence from upstream to downstream, and the cigarette 1 is wrapped with an external wrapper 106;

[0040] The airflow one-way valve section 104 has an airflow one-way valve therein, and the outer diameter of the cigarette is greater than the inner diameter of the hollow cylindrical structure of the heating chamber.

[0042] Preferably, the airflow check valve of the airflow check valve section 104 comprises: a baffle with an exhaust hole, a stopper 104-2, and a second spring 104-1 abutting against each other in sequence from upstream to downstream, wherein the second spring 104-1 is in a compressed state, and at this time, the pressure of the second spring 104-1 on the stopper 104-2 is a first elastic force;

[0043] The maximum outer diameter of the block 104-2 is smaller than the inner diameter of the cigarette, the exhaust hole is covered by the block 104-2, the maximum elastic force of the second spring 104-1 is greater than the pressure of a standard atmospheric pressure acting on the exhaust hole area, and the combined force of the first elastic force and the gravity of the block 104-2 is less than the pressure of a standard atmospheric pressure acting on the exhaust hole area.

[0044] When the stopper 104 - 2 is a cone with a small upstream diameter and a large downstream diameter, the baffle with exhaust holes can also replace the outer cone ring matching the cone, and the stopper 104 - 2 is movably arranged in a partial space inside the outer cone ring.

[0045] When the cigarette 1 is in a natural state and when exhausting, the second spring 104-1 is always in a compressed state. When the cigarette 1 is in a natural state, one end of the second spring 104-1 abuts against the stopper 104-2, and the other end of the second spring 104-1 abuts against the second air permeable baffle at the end of the airflow one-way valve section 104.

[0046] Preferably, the stopper 104 - 2 is a truncated cone.

[0047] The third aspect of the present invention provides a method for using the heated cigarette assembly according to the second aspect, which comprises the following steps:

[0048] In the natural state, the first semi-cylinder and the sealing plate 203 are combined into a hollow cylindrical structure, the vacuum suction cup 301 is in a natural state without pressure, and the first spring 204 is in a natural state, abutting against the slider 201-1, so that it does not move downward in the slide groove 202;

[0049] When smoking, the V-shaped push rod 201 rotates clockwise or counterclockwise around the slider 201-1, so that the connecting rod 206 drives the sealing plate 203 to move outward. At this time, the inner diameter of the heating chamber becomes larger and slightly larger than the outer diameter of the cigarette 1. The third spring 205 on the connecting rod 206 is compressed, and the cigarette 1 is inserted into the heating chamber.

[0050] Then, the V-shaped push rod 201 is released, and under the elastic force of the third spring 205 on the connecting rod 206, the sealing plate 203 and the connecting rod 206 are driven to move inward, and the sealing plate 203 and the first semi-cylinder are reassembled into a hollow cylindrical structure, and the cigarette 1 is clamped;

[0051] The V-shaped push rod 201 is pressed downward, driving the slider 201-1 to move vertically downward in the channel of the slide groove 202 and compressing the first spring 204. At this time, the V-shaped push rod 201 drives the connecting rod 206 and the sealing plate 203 to move downward, and the sealing plate 203 presses down the pressure ring 303 or the semicircular inner flange 301-2, so that the vacuum suction cup 301 moves downward as a whole. At this time, the funnel-shaped suction cup at the lower section of the vacuum suction cup 301 is deformed under pressure, and the slider 201-1 is inserted into the card slot 202-1 in the slide groove 202, so that the first spring 204 remains in a compressed state. At this time, the air in the vacuum suction cup 301 flows out of the cigarette 1, and because the cigarette 1 has an airflow one-way valve section 104, the outside air will no longer flow into the cigarette 1, and the funnel-shaped suction cup can be stably maintained in a compressed state;

[0052] Start the heating element 4 and start suction;

[0053] After the suction is completed, the slider 201-1 is disengaged from the slot 202-1, and the first spring 204 rebounds upward to reset, driving the slider 201-1, the V-shaped push rod 201, the connecting rod 206 and the sealing plate 203 to move upward;

[0054] At this time, the V-shaped push rod 201 is rotated clockwise or counterclockwise with the slider 201-1 as the center, so that the connecting rod 206 drives the sealing plate 203 to move outward. At this time, the inner diameter of the heating chamber becomes larger, and the cigarette 1 is taken out. At the same time, the outside air enters the vacuum suction cup 301, and the funnel-shaped suction cup at the lower section of the vacuum suction cup 301 returns to its natural state.

[0055] The working principle of the airflow one-way valve section 104 in the cigarette 1 is as follows:

[0056] During the upward flow of air in the cigarette 1, the block 104-2 covering the exhaust hole in the airflow one-way valve section 104 is pushed open, and the air is discharged from the gap between the block 104-2 and the inner wall of the cigarette 1. After the air in the cigarette 1 is exhausted, the air pressure inside the cigarette 1 is lower than the atmospheric pressure outside the cigarette 1, and the second spring 104-1 pushes the block 104-2 again to cover the exhaust hole, and the outside air cannot enter the tobacco section 105.

[0057] The present invention has the following beneficial effects:

[0058] 1. The present invention uses a movable sealing plate and a high temperature resistant vacuum suction cup combination for the first time to seal the tobacco section of a cigarette. When the present smoking device is used in conjunction with a general cigarette, it can fix the cigarette and prevent the cigarette from falling from the cigarette holding cavity. When the present smoking device is used in conjunction with an oxygen-deficient heating type cigarette, the oxygen-deficient heating type cigarette does not need to prepare a sealed tobacco section, which simplifies the preparation process of the cigarette. In addition, the sealing plate and the high temperature resistant vacuum suction cup are simple in design and easy to industrialize.

[0059] 2. The present invention also designs an oxygen-deficient heating cigarette for use with the smoking device. When smoking a cigarette, the cigarette tobacco stick has good sealing performance, and the air inside the cigarette is discharged through the airflow one-way valve section, and the outside air cannot enter, which can greatly reduce the oxygen content, so the heating temperature can be greatly increased, the aroma components in the tobacco are released more fully, and are easy to release continuously, and the taste is closer to traditional tobacco, which is more easily accepted by traditional smokers.

[0070] The content of the present invention is further explained below through specific implementation examples.

[0071] Example 1

[0072] A heating smoking device capable of assisting cigarette sealing and exhausting air from the cigarette, the smoking device comprising an auxiliary sealing component 2 and an air exhaust component 3.

[0073] The auxiliary sealing assembly 2 includes the following parts:

[0074] The heating chamber comprises a hollow cylindrical structure composed of a first semi-cylinder and a second semi-cylinder matching the first semi-cylinder, wherein the second semi-cylinder is a movable sealing plate 203;

[0075] A V-shaped push rod 201, whose V-shaped turning point is movably connected to the smoking device by means of a slider 201-1, and the V-shaped push rod 201 can rotate around the slider 201-1;

[0076] A connecting rod 206 has one end connected to the sealing plate 203 and the other end connected to one end of the V-shaped push rod 201 .

[0077] The connecting rod 206 is integrally connected to the sealing plate 203 .

[0078] The connecting rod 206 is connected to one end of the V-shaped push rod 201 by bolts.

[0079] The auxiliary sealing assembly 2 also includes:

[0080] A slide groove 202, which is arranged on the smoking device, wherein the slide groove 202 has a channel in the vertical direction that penetrates the smoking device in the thickness direction, and the slide groove 202 has a clamping groove 202-1;

[0081] The slider 201-1 is arranged in the channel of the slide groove 202, and the push rods on both sides of the V-shaped push rod 201 are respectively arranged on both sides of the slide groove 202;

[0082] The first spring 204 is disposed in the slide slot 202 , one end of which is connected to the slider 201 - 1 , and the other end of which is fixed to the bottom of the slide slot 202 .

[0083] The clamping groove 202-1 is used to fix the slider 201-1. The connecting rod 206 is provided with a third spring 205, which is arranged horizontally, with one end of the third spring 205 abutting against an outer flange on the 206 and the other end abutting against the side wall of the slide groove 202, so that the sealing plate 203 can automatically return to the initial position under the elastic force of the third spring 205.

[0084] The slide groove 202 is made of metal. The sealing plate 203 is made of peek.

[0085] The air exhaust component 3 includes a deformable vacuum suction cup 301 and a cylindrical suction cup receiving groove 302 .

[0086] The upper section of the vacuum suction cup 301 is hollow cylindrical, and the lower section has a funnel-shaped suction cup. The connection between the upper section and the lower section has a pressure ring 303 integrally connected to the inner wall of the vacuum suction cup 301. The upper section of the vacuum suction cup 301 is wrapped around the periphery of the hollow cylindrical structure of the heating chamber. The vacuum suction cup 301 has a semi-circular inner flange 301-2 on one side of the sealing plate 203. Half of the pressure ring 303 is integrally connected to the semi-circular inner flange 301-2, and the other half is integrally connected to the inner wall of the vacuum suction cup 301. The height of the pressure ring 303 is greater than the height of the semi-circular inner flange 301-2. The lower edge of the sealing plate 203 rests on the semi-circular inner flange 301-2. There is a certain gap between the vacuum suction cup 301 and the sealing plate 203, which is the space for the sealing plate 203 to move left and right. When the sealing plate 203 moves left and right, the lower edge always abuts against the semicircular inner flange 301-2. At this time, the inner diameter of the half of the quasi-cylindrical shape close to the sealing plate 203 is larger, and the inner diameter of the other half is smaller.

[0087] Of course, in other embodiments, there may be no gap between the vacuum suction cup 301 and the sealing plate 203, that is, there is no semicircular inner flange 301-2, and the sealing plate 203 directly abuts against the upper edge of the pressure ring 303.

[0088] The upper side wall of the vacuum suction cup 301 has an opening 301-1, and the connecting rod 206 passes through the opening 301-1 and is connected to the sealing plate 203. The suction cup receiving groove 302 is arranged in the smoking device, with an open upper end and a sealed bottom, and at least accommodates the lower section of the vacuum suction cup 301, and the inner diameter of the suction cup receiving groove 302 is larger than the maximum outer diameter of the funnel-shaped suction cup under the pressure limit.

[0089] The vacuum suction cup 301 is made of high temperature resistant rubber. The connecting rod 206 and the vacuum suction cup 301 are in interference fit.

[0090] The smoking device further comprises a heating element 4, which is a central heating element arranged in the center of the heating cavity. The bottom of the heating element 4 also passes through the suction cup receiving groove 302, and the contact between the two is sealed.

[0091] The first semi-cylinder is fixed to the inner wall of the hollow cylinder in the upper section of the vacuum suction cup 301. Therefore, the first semi-cylinder can move up and down with the vacuum suction cup 301.

[0092] Fixing method: The first semi-cylinder and the inner wall of the upper hollow cylinder of the vacuum suction cup 301 are bonded by an adhesive.

[0093] The specific structures and positional relationships of other parts of the smoking device are conventional designs, and the overall schematic diagram of the smoking device is not provided here.

[0095] Example 2

[0096] A heating cigarette assembly that can assist in sealing a cigarette and exhaust the air in the cigarette comprises the heating cigarette device described in Example 1 and an oxygen-deficient heating cigarette 1.

[0097] like Figure 5-6 The cigarette 1 includes a small hollow mouth rod segment 101, a filter segment 102, a large hollow mouth rod segment 103, an airflow one-way valve segment 104 and a tobacco segment 105 which are coaxially connected in sequence from downstream to upstream, and the cigarette 1 is wrapped with an external wrapper 106.

[0098] The airflow one-way valve section 104 has an airflow one-way valve therein, and the outer diameter of the cigarette is greater than the inner diameter of the hollow cylindrical structure of the heating chamber.

[0099] The design of the airflow check valve is as follows:

[0100] The airflow check valve section 104 has a hollow cavity, and the hollow cavity includes a first truncated cone, a second large cylindrical section, and a third small cylindrical section with diameters from small to large from upstream to downstream. The maximum diameter of the first truncated cone is equal to the diameter of the second large cylindrical section, which is larger than the diameter of the third small cylindrical section. A truncated cone-shaped stopper 104-2 and a second spring 104-1 are provided in the hollow cavity from upstream to downstream, which are abutted against each other in sequence. The stopper 104-2 matches the small diameter section of the first truncated cone and can at least move in the first truncated cone. The second spring 104-1 is arranged in the first truncated cone, the second large cylindrical section, and the third small cylindrical section.

[0101] The second spring 104-1 is in a compressed state, and the pressure of the second spring 104-1 on the block 104-2 is the first elastic force. The maximum elastic force of the second spring 104-1 is greater than the pressure of a standard atmospheric pressure acting on the surface of the block 104-2 with a smaller diameter of the truncated cone. The combined force of the first elastic force and the gravity of the block 104-2 is less than the pressure of a standard atmospheric pressure acting on the surface of the block 104-2 with a smaller diameter of the truncated cone. This makes the airflow check valve section have the function of unidirectionally conducting airflow within the elastic force range of the second spring 104-1.

[0102] When the cigarette 1 is in a natural state and when exhausting, the second spring 104-1 is always in a compressed state. When the cigarette 1 is in a natural state, one end of the second spring 104-1 abuts against the stopper 104-2, and the other end of the second spring 104-1 abuts against the second air permeable baffle at the end of the airflow one-way valve section 104, which is not shown in the figure. The side wall of the large hollow mouthpiece section 103 has a through hole connected to the outside air, which is not shown in the figure.

[0103] Example 3

[0104] This embodiment 3 provides a method for using the heated cigarette assembly described in embodiment 2, which comprises the following steps:

[0105] In the natural state, the first semi-cylinder and the sealing plate 203 are combined into a hollow cylindrical structure, the vacuum suction cup 301 is in a natural state without pressure, and the first spring 204 is in a natural state;

[0106] When smoking, the V-shaped push rod 201 rotates counterclockwise around the slider 201-1, so that the connecting rod 206 drives the sealing plate 203 to move outward. At this time, the inner diameter of the heating chamber becomes larger and is slightly larger than the outer diameter of the cigarette 1. The third spring 205 on the connecting rod 206 is compressed, and the cigarette 1 is inserted into the heating chamber.

[0107] Then, the V-shaped push rod 201 is released, and the sealing plate 203 and the connecting rod 206 are driven to move inwards under the elastic force of the third spring 205 on the connecting rod 206, and the sealing plate 203 and the first semi-cylinder are reassembled into a hollow cylindrical structure, and the cigarette 1 is clamped. Figure 7 As shown;

[0108] The V-shaped push rod 201 is pressed downward, driving the slider 201-1 to move vertically downward in the channel of the slide groove 202 and compressing the first spring 204. At this time, the V-shaped push rod 201 drives the connecting rod 206 and the sealing plate 203 to move downward, and the sealing plate 203 presses down the semi-circular inner flange 301-2 in the vacuum suction cup 301, so that the vacuum suction cup 301 moves downward as a whole. At this time, the funnel-shaped suction cup at the lower section of the vacuum suction cup 301 is deformed under pressure, and the slider 201-1 is inserted into the slot 202-1 in the slide groove 202, so that the first spring 204 remains in a compressed state. At this time, the air in the vacuum suction cup 301 flows out of the cigarette 1, and since the cigarette 1 has an airflow one-way valve section 104, the outside air will no longer flow into the cigarette 1, and the funnel-shaped suction cup can be stably maintained in a compressed state. Figure 8 As shown;

[0109] Start the heating element 4 and start suction;

[0110] After the suction is completed, the slider 201-1 is disengaged from the slot 202-1, and the first spring 204 rebounds upward to reset, driving the slider 201-1, the V-shaped push rod 201, the connecting rod 206 and the sealing plate 203 to move upward;
