Description

Valve with skirt edge for upstream of particle-type smoke generation section and particle-type cigarette

Technical Field

The utility model belongs to the technical field of heating cigarettes, and particularly relates to a valve with a skirt edge and used on the upstream of a particle-type smoking section and a particle-type cigarette.

Background

The existing particle type heating non-combustible product is a complete cigarette, and is formed by a hollow paper tube, after the front end of the hollow paper tube is bonded with thin paper with extremely high air permeability, a particle type smoking material which can be heated to generate aerosol is filled, then an isolation plug used for preventing the particle type smoking material from axially jumping in the cigarette is sequentially filled, then a temperature reduction section for reducing the temperature of the heated smoke along the length direction of the paper tube is arranged, and finally a filter material section for further filtering the smoke is filled at the tail end of the paper tube, so that a complete particle type cigarette is formed. However, when a cigarette is heated, a heating element such as a heating needle or a heating sheet needs to pierce through a highly breathable thin paper adhered to the front end of the cigarette, and the highly breathable thin paper is easily torn, so that the granular smoking material cannot be effectively blocked. And the high-permeability thin paper is not easy to be adhered to a paper tube or (and) has not high reliability after being adhered in the processing and manufacturing process.

In addition, in the existing particle heating cigarette product, the raw and auxiliary materials comprise a plurality of thin paper films, fuming particles, plastic separators, paper tubes, filtering materials and the like. Therefore, although a dedicated device is manufactured, the device operation is complicated at the time of manufacturing. In addition, because the cigarette supplies are various and the attributes of the supplied materials are greatly different, some materials of the used cigarette cannot be rapidly and naturally degraded. In addition, the production efficiency of the special equipment is not high, the equipment investment is also large, and the special equipment is not suitable for various investors.

The utility model is made in order to reduce the dependence on expensive and inefficient cigarette manufacturing equipment and solve the problem that the cigarette is easy to tear due to the use of high-permeability thin paper as far as possible.

Compared with the prior art, the utility model has the following beneficial effects:

1. the utility model provides a skirted valve for use upstream of a pellet-type smoking segment. The skirt has the functions of: (1) the axial length of the plugging piece is increased, so that the plugging piece is easy to fill in a smoke tube and is not easy to rollover and clamp a shell; (2) the supporting function of the plugging piece in the smoke tube is enhanced; (3) because friction force exists between the skirt edge and the smoke tube, the reliability of the valve fixed in the smoke tube is improved; (4) the manual assembly of the cigarettes is facilitated, the laziness to cigarette filling equipment is reduced, and the access threshold of the product is further reduced; (5) because the central heating smoking set does not significantly heat the smoking material adjacent the tube, uneven heating is a more probable event if factors such as cigarette wobble during smoking are not considered. Thus, a skirt is added to the tube, which occupies a portion of the space within the tube adjacent the tube, which reduces the loading of smoking material without significantly affecting the amount of smoke generated.

The main cuts 11 have the function of: the central heating element is used for being inserted, and after the central heating element is pulled out, the diaphragm 1 part at the main cutting mark 11 can restore to the original shape or restore to the approximate original shape by the elasticity of the diaphragm, and the particulate smoking material in the cigarette branch is still blocked, so that the smoking set or the use environment is prevented from being polluted.

3. In a preferred embodiment, the valve of the present invention has a central cut 12, a vertical cut 13, and a distal cut 14 in addition to the main cut 11. The combination of the cutting marks has the following functions: (1) when the heating element of the heating smoking set matched with the cigarette is a sheet heating element or a cross heating element, when the heating element is inserted, the membrane 1 can be deformed in a self-adaptive manner by utilizing the natural elasticity of the membrane along the directions of the central cut mark 12, the vertical cut mark 13 and the tail end cut mark 14, and the membrane 1 is not easy to tear; (2) after the sheet type heating element or the cross-shaped heating element is pulled out, the membrane 1 can restore to the original shape or be restored to the original shape by the elasticity of the membrane, and the particle fuming material in the cigarette is still blocked, so that the smoking set or the using environment is prevented from being polluted; (3) since the cut portion is not completely sealed, air is allowed to flow in during suction.

4. The purpose of setting up the frame opening on the frame: for cigarettes with smaller cigarette diameter, the cross-shaped frame opening, especially the cross-shaped structure, can strengthen the radial strength of the frame main body and prevent the frame main body and the membrane 1 from being torn; the sheet heating element is guided in such a way that it can be inserted into the main cut 11 with precision.

5. In the preferred technical scheme, indexes such as air permeability of the valve and cigarette suction resistance can be properly adjusted by selecting the number and the size of the inner concave part 24 between the skirt edges 22.

As shown in fig. 1, a skirted valve for use upstream of a granular smoking segment, the valve comprising: a membrane 1 and a frame 2 bonded to one side of said membrane 1. The whole valve is made of paper.

The "side" is shown in the front view of fig. 1 as the front of the membrane 1.

The frame 2 includes a frame body and sixteen skirts 22 spaced from each other and disposed about the periphery of the frame body. Each skirt 22 is substantially rectangular sheet-like. The short side of each skirt 22 is connected to the frame body by a crease line 23. The center of the frame body is provided with a cross-shaped frame opening 21. The edges of the frame opening 21 are all rounded curves. The cross-shaped frame opening 21 corresponds to the shape of a heating element of a heating smoking set for later use of cigarettes, the cross-shaped frame opening 21 in the figure 1 can correspond to a common needle type central heating, sheet type heating and cross heating body, and if heating elements in other forms exist, the cross-shaped frame opening can be changed into the corresponding frame opening shape. The frame body is in the shape of a circular sheet, the edges of the frame body are spaced by inner recesses 24, and the adjacent skirt edges 22 are spaced by the inner recesses 24.

The membrane 1 is in the shape of a circular sheet, and the edge of the membrane 1 is also spaced with an inner concave part so that the membrane 1 is completely overlapped with the edge of the frame body. The center of the membrane 1 is provided with a pair of mutually perpendicular main cuts 11, and the main cuts 11 are positioned in the center of the cross-shaped frame opening 21. The main cut 11 is in a cross shape. Two central cuts 12 are formed at the center of the main cut 11 so as to intersect the main cut 11 at a constant angle of 45 degrees. The central cut 12 and the main cut 11 are in a shape of a Chinese character 'mi'. Eight vertical cuts 13 which are communicated with the main cut 11 and are vertical to the main cut 11 are arranged along the four directions of the main cut 11. The four ends of the main cut 11 are each provided with one end cut 14 communicating therewith and perpendicular thereto.

The shape of the cross-shaped frame opening 21 corresponds to the shape of a heating element of a heating smoking set for cigarette future use, the cross-shaped frame opening 21 in figure 1 corresponds to common needle type central heating, sheet type heating and cross heating bodies, and the shape of the corresponding opening can be changed if other types of heating elements are provided.

The central cut 12 has the function of: the utility model prevents the leakage of the smoking material filled in the cigarette, and simultaneously facilitates the insertion of a heating element heated in the center into the smoking section part of the cigarette.

The length of the central cut 12 is a, which is 1.2-1.8 times of the diameter of the needle-type or rod-type central heating element. The length of the vertical cutting mark 13 is b, and the value of b is 1.1-1.5 times of the thickness of the sheet type heating element. The length of the end cut 14 is c, and the value of c is 1/3-4/5 of b.

The main cut 11, the center cut 12, the vertical cut 13 and the end cut 14 have the following combined functions:

1. when a cigarette formed by the valve is matched with a sheet or cross-shaped heating element for use, the cutting mark gives a predeformation direction to the membrane 1, and the membrane 1 is prevented from being damaged because the insertion of the sheet heating element exceeds the elastic adaptation range of the membrane 1;

2. effectively preventing the smoke particles filled in the smoke generating section from leaking out to pollute the smoking set or leaking out in the non-use stage;

3. meanwhile, the cut is not completely sealed, so that air is allowed to flow in during suction.

In a second embodiment, as shown in fig. 2-3, the frame body is in the shape of a regular octagon, and a skirt 22 is connected to each side of the regular octagon. The skirt 22 is of a rectangular sheet-like configuration with the short sides of the rectangle being connected to each side of the regular octagon. The length of the skirt 22 is 0.5-1.5 times of the diameter of the circumscribed circle of the frame body. The valve is mainly suitable for products with the diameter of cigarette less than 7 mm. The diameter of the circumscribed circle of the frame main body is slightly larger than the inner diameter of a cigarette so as to realize interference fit.

Because of the practical size limitation, the valve reduces the number of the skirt edges 22, and the number of the skirt edges 22 is recommended to be 6-8, so that the shape of the frame opening 21 is further simplified, the length of the main cutting mark 11 is reduced, and the vertical cutting mark 13 and the tail end cutting mark 14 are combined into a whole. At this time, the length of the end cut 14 is suggested to be in a range of b, and the value of b is 1.1 to 1.5 times of the thickness of the sheet type heating element.

In a third embodiment, as shown in fig. 4, based on the first embodiment, the valve further comprises a support frame body 3. The support frame body 3 is arranged at the other side of the membrane 1. The membrane 1 is bonded in the middle by using the frame 2 and the support frame body 3, and the membrane 1 is supported and fixed more stably. The support frame body 3 is identical to the frame body of the frame 2.

In a fourth embodiment, as shown in fig. 5, based on the second embodiment, the valve further comprises a support frame body 3. The support frame body 3 is arranged at the other side of the membrane 1. The center of the support frame body 3 is provided with an opening identical to the cross-shaped frame opening 21, that is, the support frame body 3 is identical to the frame main body part of the frame 2. The membrane 1 is bonded in between using a frame 2 and a support frame 3. The centers of the frame main body, the support frame body 3 and the membrane 1 are opposite.

Referring to fig. 6, a fifth embodiment provides a particle type cigarette, which comprises a cigarette tube, wherein a particle type smoking section I, a middle blocking section II, a cooling section III and a filter section IV are sequentially arranged in the cigarette tube from a far lip end to a near lip end. The valve of the second embodiment is arranged at the lip end of the far end of the smoke tube. I.e. the distal labial end of the particle-type smoking segment I is blocked by the valve described in the second embodiment to prevent leakage of the smoker particles while being used for insertion of the heating element. The smoke tube is a paper tube. The frame main body of the valve is in a regular polygon sheet shape, the diameter of a circumscribed circle of the regular polygon is larger than the inner diameter of the smoke tube, and a gap allowing smoke to flow exists between the outer edge of the frame main body and the inner wall of the smoke tube. The middle plugging piece II is coaxially arranged with the smoke pipe. The middle plugging piece II is of a hollow cylindrical structure and is internally provided with a diaphragm plate. The outer diameter of the hollow cylindrical structure is basically equal to or slightly larger than the inner diameter of the smoke tube, so that the side wall of the hollow cylindrical structure is in interference fit with the inner wall of the smoke tube. The diaphragm plate blocks the fuming particles of the fuming section I. The diaphragm plate is provided with a vent hole. The size of the ventilation holes is smaller than the size of the smoker particles. Figure 6 shows a main axial section and a section a-a of a particulate cigarette according to a fifth embodiment.
