Description

Multifunctional device Aerosol generating article

Technical Field

The invention relates to the field of aerosol generating products, in particular to a multifunctional aerosol generating product.

Background

Along with the improvement of living standard, the health consciousness of people is continuously improved, and the attention of people to' health aerosol products is higher and higher. In order to meet the changing consumption demands, various novel heating aerosol generating products for replacing the traditional cigarettes are developed in great numbers for various enterprises at home and abroad.

The heating non-combustion product is characterized in that a special heating source is used for heating the aerosol generating substrate section within 300 ℃, the aromatic substances in the aerosol generating substrate section volatilize to generate aerosol to meet the requirements of a smoker, and the aerosol generating substrate section of the heating non-combustion aerosol generating product is in a non-combustion state when being smoked, unlike a traditional cigarette, so that harmful components generated by high-temperature combustion and pyrolysis of the aerosol generating substrate can be reduced.

At present, aerosol generating products mainly comprise two forms of wrapping and rolling and integral filling, wherein the integral filling is to select an integral pipe body with certain hardness and wall thickness as an outer pipe, and then the aerosol generating unit, the supporting and blocking unit, the cooling and filtering unit and the like are sequentially filled in the pipe body in a filling mode. The aerosol generating units of the integrally filled aerosol generating product have the advantages of more various forms, no need of being limited to filaments or sheets which are convenient to roll, no need of using rolling equipment, simple preparation method and the like, and are gradually focused on.

The end face of the tube on the side of the aerosol generating unit of prior art aerosol generating articles is air permeable which allows the passage of air into the aerosol generating unit so that externally introduced air carriers draw in aerosol generated by the aerosol generating unit and together into the consumer's mouth. That is, the outer tube of the conventional aerosol-generating article in the form of a single-piece package is not provided with a vent hole, but is fed through the end face on the side of the aerosol-generating substrate, but since the aerosol-generating unit contains the air introduced therein, the oxygen concentration is high, the heating temperature must be lower than 300 ℃, and otherwise there is a risk of burning, so that the concentration of the aerosol entering the oral cavity of the consumer at the antipyretic temperature is low. In addition, the existing aerosol heating device is provided with a common aerosol heating device which allows air to enter the aerosol generating unit and an oxygen-poor aerosol heating device which does not allow air to enter the aerosol generating unit, and the aerosol generating product is only applicable to a certain type of aerosol heating device and cannot be matched.

Therefore, it would be desirable to develop a one-piece filled aerosol-generating article that ensures aerosol concentration and that is compatible with both types of aerosol-heating devices.

The present invention has been made to solve the above problems.

Preferably, the axial heights of the first ventilation hole 31 and the second ventilation hole 71 are identical, and the sleeve 7 is rotatable with respect to the pipe body 5, so that the second ventilation hole 71 is shifted between opposite and offset positions with respect to the first ventilation hole 31. Or the axial heights of the first ventilation hole 31 and the second ventilation hole 71 are not uniform, and the sleeve 7 can move axially relative to the pipe body 5, so that the second ventilation hole 71 and the first ventilation hole 31 are switched between opposite and dislocation. That is, the two can be rotated or pushed and pulled in the axial direction.

Preferably, the multifunctional aerosol-generating article means a first function, wherein the second ventilation hole 71 is opposite to the first ventilation hole 31, and allows outside air to enter the aerosol-generating article through the second ventilation hole 71 and the first ventilation hole 31, and the sealing member 6 is breathable, and after the aerosol-generating article is inserted into the aerosol-heating device, a sealing member is arranged on the contact part of the aerosol-heating device and the sealing member 6, so that the sealing member 6 is sealed to ensure that air cannot enter the aerosol-generating unit 1 through the sealing member 6;

The second function, the second ventilation hole 71 is dislocated with the first ventilation hole 31, and does not allow external air to enter the aerosol generating product through the second ventilation hole 71 and the first ventilation hole 31, the sealing member 6 is ventilation, and air enters the aerosol generating unit 1 through the sealing member 6.

Preferably, a functional section 3 is provided between the barrier section 2 and the filter section 4.

The functional section 3 is of a single cavity structure or is filled with functional materials, the functional materials are selected from one or more of cooling materials, aroma-enhancing materials and filtering materials, and the functional materials are in the form of one or more of explosive beads, particles, slow-release gel, powder, paste and disordered materials. Preferably, the functional material aims at fragrancing the aerosol while reducing the temperature of the aerosol, and reducing the harmful components in the aerosol. The functional material is selected from, but not limited to, diatomite, fragrant particles, activated carbon, heat conducting gel, hydrated salt cooling material, and waxy material.

Preferably, the axial positions of the second ventilation holes 71 and the first ventilation holes 31 are located between the end face of the functional section 3 near the filtering section 4 and the end face of the aerosol generating unit 1 near the blocking section 2.

More preferably, the axial positions of the second ventilation holes 71 and the first ventilation holes 31 are located at the functional section 3 and near the side of the blocking section 2. That is, the second ventilation holes 71 and the first ventilation holes 31 may be provided at any position of the barrier section 2 and the functional section 3, but more preferably, the second ventilation holes 71 and the first ventilation holes 31 are located on the functional section 3 and are axially closer to the barrier section 2.

Preferably, after the aerosol-generating article is inserted into the aerosol-heating device, the axial height of the second ventilation hole 71 and the first ventilation hole 31 is lower than the axial height of the highest point of the heating element of the aerosol-heating device. The purpose of defining the axial height of the second ventilation holes 71 and the first ventilation holes 31 to be lower than the axial height of the highest point of the heating element of the aerosol-heating device is to make the aerosol-heating device more suitable for oxygen-deficient heating, to produce a higher concentration of aerosol, to give a more intense fragrance, and to give a higher sensory evaluation of suction.

Preferably, the outer diameter of the tube body 5 is smaller than or equal to the inner diameter of the sleeve 7.

Preferably, the diameter of the first ventilation holes 31 may be 0.01-3.5 mm, the number of the first ventilation holes is 1-35, and the diameter of the second ventilation holes 71 may be 0.01-3.5 mm, the number of the second ventilation holes is 1-35.

Preferably, the second ventilation holes 71 and the first ventilation holes 31 are perforated by laser perforation or mechanical perforation, and the perforation is not limited to this method, and may be any perforation method as long as it can perforation a tube body with a certain thickness and hardness, or may be selected according to the material pertinency of the tube body. The second ventilation holes 71 and the first ventilation holes 31 may be pre-perforated before filling each section of the pipe 5, or may be perforated after filling is completed. This pre-perforation means that the tube 5 is perforated when it is not filled with aerosol-generating units 1, barrier sections 2 and filter sections 4.

Preferably, the outer layer of the tube body 5 is further wrapped with a label paper for the purpose of aesthetic appearance and preventing the aerosol generating material in the tube body 5 from leaking outside the paper tube. If the tube body 5 is pre-perforated, it is preferable to make holes after wrapping the label paper on the outer layer of the tube body 5, and when the holes are made, the label paper and the tube body 5 need to be perforated, so that the external air is introduced into the aerosol generating product.

Preferably, the closure 6 is breathable. The closure 6 may be selected from a breathable material, such as a paper material or an inorganic porous material, such as alumina, silicon carbide, silicon nitride or diatomaceous earth, which is breathable by itself, or a non-breathable material, such as a perforated form, which is selected from a resin material, such as PEEK, polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate or polylactic acid.

The key point emphasized by the invention is that the aerosol generating product can be simultaneously applied to an oxygen-deficient heating type aerosol heating device and an existing common air inlet heating type aerosol heating device. The two functions are switched, and whether the sealing piece 6 and the second ventilation holes 71 are matched with the first ventilation holes 31 or not allows gas to pass through is needed.

When the aerosol-generating article having the vent is heated using the existing conventional air intake, the closure member 6 is air permeable, allowing air to pass therethrough and into the aerosol-generating substrate, while the second vent 71 is displaced from the first vent 31, and does not allow ambient air to enter the aerosol-generating article through the second vent 71 and the first vent 31.

When the aerosol-generating article with the vent hole adopts oxygen-deficient heating, after the aerosol-generating article is inserted into the aerosol-heating device, a sealing piece is arranged on the contact part of the aerosol-heating device and the sealing piece 6 so as to seal the sealing piece 6, thus ensuring that air cannot enter the aerosol-generating unit 1 through the sealing piece 6, and the second vent hole 71 is opposite to the first vent hole 31, so that external air is allowed to enter the aerosol-generating article through the second vent hole 71 and the first vent hole 31.

Preferably, the filter section 4 is a common filter piece selected from paper, polylactic acid, acetate fiber, cotton and resin, or a characteristic filter piece selected from a hollow filter rod, a concentric filter tip, a groove filter tip, a color filter tip and a filter tip added with explosion beads.

Preferably, the aerosol-generating unit 1 is an aerosol-generating substrate in the form of particles, powder, filaments, gel or paste. The form of the aerosol-generating substrate is merely exemplified here, but the present invention is not limited to the above forms, and any aerosol-generating substrate that can be incorporated into the tube body 1 is applicable.

Preferably, the tube body 5 is selected from, but not limited to, paper tubes.

Preferably, the aerosol-generating article further comprises an end cavity at the end of the proximal lip end side, the end cavity being defined by the tube. While some smokers 'insides may be unsafe when they are in direct contact with the filter material of the cigarette filter segment, the end cavity of the aerosol generating article is designed to allow the smokers' mouth to contact only the tube body and not the filter material, eliminating some of the above-mentioned doubts and better protecting the filter unit.

Compared with the prior art, the invention has the following beneficial effects:

1. In the prior art, holes are usually punched in tipping paper or forming paper of a rolled aerosol generating product, no research on punching the outer wall of a hard paper tube of the integrally filled aerosol generating product exists, and the invention overcomes the prejudice of the prior art and firstly thinks of punching holes in the hard tube of the integrally filled aerosol generating product.

2. The outer side of the pipe body 5 is also provided with a sleeve 7, the sleeve 7 is provided with a second ventilation hole 71, and the sleeve 7 can rotate relative to the pipe body 5, so that the second ventilation hole 71 and the first ventilation hole 31 are switched between opposite and dislocation. That is to say, it is possible to realize that air is allowed to be introduced into the functional section 3 or that switching between air introduction into the functional section 3 is not allowed, so that it is ensured that it is suitable for both the oxygen-deficient aerosol heating device and the ordinary aerosol heating device.

When the first function is that the air is allowed to be introduced into the functional section 3, the aerosol generating product can be used for an oxygen-deficient aerosol heating device, at the moment, after the aerosol generating product is inserted into the aerosol heating device, a sealing piece is arranged at the contact part of the aerosol heating device and the sealing piece 6 so as to seal the sealing piece 6, the air cannot enter the aerosol generating unit 1 through the sealing piece 6, the aerosol generating unit 1 is in an oxygen-deficient state, and even if the temperature reaches 300 ℃ or more, combustion cannot be generated, so that the aerosol generating unit 1 can be heated to a higher temperature, the generated aerosol concentration is high, and the second ventilation holes 71 at the functional section 3 and the first ventilation holes 31 are converged, and the air has an extraction effect on the aerosol generated by the aerosol generating unit 1, so that the aerosol concentration can be ensured. In addition, when the heating temperature is higher than 300 ℃, combustion can still not be generated, and the higher heating temperature is favorable for fully realizing fragrance release and improving the fragrance quantity. The heat loss is small, the heating efficiency is higher, and the sensory evaluation is better.

In a second function, when it does not allow air to be introduced into the functional section 3, the aerosol-generating article can be used in a common aerosol-heating device, in which case the aerosol-heating device can be used in a wider range, with external air entering the aerosol-generating unit 1 through the closure member 6.
