Description

Smoking substitute device with shield

The present disclosure is related to the field of smoking grass. In detail, the present disclosure is related to smoking replacement systems, and particularly (but not exclusively) to heat not burn (HNB) smoking replacement systems. In further detail, the present disclosure is related to a smoking replacement system with a shield.

It is generally believed that smoking grass exposes smokers to potentially harmful substances. It is generally believed that a large amount of potentially harmful substances are produced through the heat caused by the burning and/or burning of tobacco and the burning tobacco components in the tobacco smoke itself.

Conventional flammable smoking products (such as cigarettes) generally include cylindrical tobacco rods and usually also cylindrical filters. Cylindrical tobacco rods include shredded tobacco surrounded by wrapping paper, and the filter is adjacent to the wrapped tobacco rod. Align the ground axis. Filters generally include filter material enclosed by a plug sleeve. The wrapped tobacco rod and the filter are joined together by a wrapped tipping paper tape, which wraps the entire length of the filter and the adjacent part of the wrapped tobacco rod. This conventional cigarette is used by igniting the end opposite to the filter and burning the tobacco rod. Smokers receive mainstream smoke into their mouths by smoking at the mouth end or filter end of the cigarette.

It is known that the burning of organic materials (such as tobacco) produces tar and other potentially harmful by-products. Various smoking alternative systems (or "alternative smoking systems") have been proposed to avoid smoking grass.

This type of smoking replacement system can form part of nicotine replacement therapy, which is aimed at people who want to stop smoking and overcome their dependence on nicotine.

Smoking alternative systems include electronic systems that allow users to simulate smoking by generating smoke (also called "vapor"). The smoke is drawn into the lungs through the mouth (inhalation) and then exhaled. Inhaled smoke generally contains nicotine and/or flavoring agents, which do not have or have less odor and health risks associated with traditional smoking.

In general, the smoking substitution system aims to provide alternatives to smoking rituals, while at the same time providing a similar experience to users and providing satisfaction to those who have experience in traditional smoking and flammable tobacco products. Some smoking replacement systems use smoking replacement products that are designed to resemble traditional cigarettes that are cylindrical in form and have a mouthpiece at one end.

In the past few years, the popularity and use of smoking alternative systems has grown rapidly. Although originally marketed as an aid to habitual smokers who wish to quit smoking, consumers increasingly regard the smoking alternative system as a desirable lifestyle accessory.

There are many different types of smoking replacement systems, each using a different method of smoking replacement.

One method used for smoking alternative systems is the so-called "heat not burn" ("HNB") method, in which tobacco (rather than "e-liquid") is heated or warmed to release vapor. The tobacco can be tobacco leaf or reconstituted tobacco. The vapor may contain nicotine and/or flavoring agents. In the HNB method, the intention is that the tobacco is heated but not ignited, that is, the tobacco does not experience combustion.

A typical HNB smoking replacement system can include equipment and consumables. The consumable may include tobacco material. The equipment and consumables can be configured to be physically coupled together. During use, the heating element of the device can be used to impart heat to the tobacco material, wherein the air flow through the tobacco material causes the moisture in the tobacco material to be released as vapor. The vapor may also be formed by a carrier in the tobacco material (this carrier may, for example, include propylene glycol and/or vegetable glycerin) and additional volatile compounds released from the tobacco. The released vapor can be entrained in the air stream drawn through the tobacco.

As the vapor passes through the consumable (entrained in the air stream) from the inlet to the mouthpiece (outlet), the vapor cools and condenses to form smoke for inhalation by the user. Smoke will usually contain volatile compounds.

In the HNB smoking replacement system, heating rather than igniting the tobacco material is believed to result in fewer or smaller amounts of the more harmful compounds that are usually produced during smoking. Therefore, the HNB method can reduce the odor and/or health risks that may be caused by the ignition, combustion, and pyrolysis degradation of tobacco.

It may be necessary to improve the design of smoking replacement systems (especially HNB smoking replacement systems) to enhance the user experience and improve the function of HNB smoking replacement systems.

This disclosure is designed in view of the above considerations.

At least one such requirement can be met with the subject of a separate item. The preferred embodiments can be adopted from the appendix, and are explained in more detail in the following description with respect to the provided drawings.

In the broadest sense, the present disclosure is related to an aerosol-forming delivery system (such as a smoking replacement system, such as an HNB system). More specifically, the present disclosure is related to a smoking alternative device with a shield (especially an isolated or insulating shield) for thermally insulating or thermally separating the heating element, in particular at least partially covering or Surrounding smoking alternative consumables.

According to a first aspect of the present disclosure, there is provided a smoking alternative device, including: a main body; a cavity; and a heating element; wherein the cavity is arranged in the main body; wherein the heating element is arranged in the interior of the cavity; wherein The smoking substitute device is adapted to receive a smoking substitute consumable; wherein the heating element is adapted to heat the smoking substitute consumable; and the smoking substitute device includes a shield that at least partially surrounds the cavity and particularly heats The element (14) is thermally insulated.

According to another aspect of the present disclosure, a smoking replacement system is provided, which includes a smoking replacement device and a smoking replacement consumable according to the present disclosure.

According to a third aspect of the present disclosure, there is provided a method of using the smoking replacement system according to the present disclosure. The method includes the following steps: inserting a smoking replacement consumable into a smoking replacement device; and using a heating element to heat the smoking replacement consumable .

The ideas and concepts of this disclosure can be considered based on the following observations and findings.

As previously mentioned, the present disclosure relates to smoking replacement systems. The smoking replacement system may include a smoking replacement device or a smoke forming device, and these devices may be heat not burn (HNB) smoking replacement devices. HNB equipment is equipment that is adapted to heat but not burn a smoke-forming substrate. This substrate may be made of tobacco material and may include additives that assist in the formation of smoke from the smoking replacement device. The smoking replacement device may include a main body for housing the heating element. The heating element may include an elongated (for example, rod-shaped, tubular, or blade-shaped) heating element. The heating element may protrude into or surround the cavity in the main body of the smoking substitute device, and the cavity is used to receive smoking substitute consumables.

The smoking alternative device may include a power source (for example a (rechargeable) battery) for powering the heating element. It may further include a control unit to control the power supply to the heating element.

In some embodiments, when the consumable is inserted into the cavity in the main body, after the smoking replacement consumable is inserted, a part of the smoking replacement consumable is penetrated by the heating element. In detail, the heating element can penetrate the smoking substitute consumable in the consumable area where the smoke-forming substrate (for example, tobacco material) is arranged.

The heating element is therefore arranged inside the smoking replacement consumable and especially the tobacco material. When energy is supplied to the heating element, the heating element is heated to a target temperature, which is preferably in a range that exceeds the vaporization temperature of the nicotine contained in the tobacco material but is lower than the temperature at which the tobacco material will start to ignite or burn. For example, the heating element can be heated to a temperature above 170°C (the vaporization temperature of nicotine) but below 400°C (to avoid igniting the tobacco material in the consumable). Preferably, the target temperature may not exceed about 350°C.

The optional features will now be listed. These features are applicable individually or in any combination with any aspect of the present disclosure. In the context of this manual, the terms "isolation shield", "insulation shield", "isolation shield", and "shield" should be understood as interchangeable.

According to the present disclosure, the smoking replacement device includes a shield. In detail, the insulating shield can be arranged near the heating element, and can be arranged to maintain or keep the heat in the smoking alternative device and to remove the heat generated in the smoking alternative device from the outside (such as holding the smoking cigarette). The user of the replacement device) shielded.

In other words, the insulating shield can be arranged to maintain the thermal energy contained in the interior of the insulating shield, which can particularly receive smoking alternative consumables while maintaining a substantially lower external temperature (for example, suitable for contact with the user’s skin). Cooler temperature in order to avoid damage caused by heat). The isolating shield can be implemented as an elongated, substantially cylindrical tube of suitable dimensions for receiving smoking alternative consumables. During the operation of the smoking substitute device, the consumables can be inserted into the cavity of the smoking substitute device, and in particular into the insulating shield surrounding the cavity. The heating elements can be arranged in the cavity and the central part of the insulating shield, respectively, so as to provide a heat source in the inner volume of the insulating shield.

For example, the heating element may penetrate the smoking alternative consumable in a suitable area or area to contact the tobacco material or another aerosol forming substrate located in at least a portion of the smoking alternative consumable. Smoking replacement consumables can in turn be surrounded by an insulating shield. In other words, the inserted smoking replacement consumables can be sandwiched between the heating element and the insulating shield.

The heat generated by the heating element and released to the tobacco material thus heats the tobacco material to the desired operating temperature. As previously mentioned, the heating element is arranged within the tobacco material. During the heating process or during the operation of the smoking replacement device, the tobacco material is heated substantially uniformly, so that the outer surface area or peripheral area of the smoking replacement consumable is also heated to the operating temperature. Therefore, the insulating shield surrounding at least a portion of the smoking substitute consumable at least partially prevents heat from leaving the volume contained within the insulating shield. In other words, the isolating shield forms a protective barrier (especially a thermal barrier) between the interior of the isolating shield containing smoking substitute consumables and heating elements and the outside of the isolating shield, which can be in contact with the user's body. Contact with the outside of the smoking alternative device is related. The optional features will now be listed. These features are applicable individually or in any combination with any aspect of the present disclosure.

The shield can be coated in a heat reflective substance to reflect heat toward the consumable to promote internal heating and insulate the outer surface. The shield may be a tubular part, and when in use, the cavity for consumables is located in the tubular part. The shield may extend at least the entire length of the heater rod, may be a part of the device, and may include an engagement member to releasably engage the top cover. The shield may be engaged with the cavity, and may include a component (such as a hinged arm) that penetrates through the cavity wall for entry and exit from the cavity. The shield may have holes for cleaning the base of the rod heater. The hole can be small enough to prevent fingers from touching the rod heater. The increased isolation and heat retention can increase battery efficiency and can prevent the temperature reaching the outside of the device from exceeding the required (especially safe) operating or manipulation temperature.

According to an embodiment of the present disclosure, the heating element may be arranged as a heater rod provided with the main body; and wherein the shield (38) may surround at least a part of the heater rod so as to thermally isolate or heat the heater rod insulation.

According to an embodiment of the present disclosure, the cavity may be adapted to receive a smoking substitute consumable, and the insulating shield may at least partially surround at least a part of the received smoking substitute consumable.

By arranging the smoking substitute consumables inside the insulating shield, the heat contained in the smoke generating material (such as tobacco material) can be maintained inside the insulating shield while maintaining a cooler surrounding environment.

According to a further embodiment of the present disclosure, the heating element can be adapted to penetrate the outer surface of the smoking alternative consumable after inserting the smoking alternative consumable into the smoking alternative device to interact with the tobacco located inside the smoking alternative consumable Material contact for heating the tobacco material.

The tobacco material is thus sandwiched between the heating element and the insulating shield to provide a preferably thermally conductive volume into the tobacco material while maintaining a cooler surrounding area.

According to another embodiment of the present disclosure, the insulating cover can thermally insulate the inside of the insulating cover from the outside of the insulating cover.

The insulating shield thus constitutes a thermal barrier within the smoking alternative device, thereby separating the higher temperature volume in the interior of the insulating shield from the exterior having a reduced temperature.

According to a further embodiment of the present disclosure, the insulating shield may be made of a polymer material, in particular, it may be made of polyether ether ketone (PEEK).

Polymeric materials may be the preferred materials for forming the insulating element. PEEK is a linear, semi-crystalline, thermoplastic high-performance plastic (high-performance material), which has a very high melting temperature of over 330°C. PEEK has very high heat resistance and good chemical resistance. PEEK is resistant to almost all organic and inorganic chemicals, even resistant to hydrolysis up to about 280°C. It has a very high continuous service temperature up to 260°C and very high strength, very high rigidity and high toughness. In addition, PEEK has excellent abrasion resistance and excellent sliding properties as well as a low linear thermal expansion coefficient. Plastic is flame-retardant and self-extinguishing, and produces very little smoke in the event of a fire.

According to another embodiment of the present disclosure, the interior of the insulating shield may be coated with a heat-reflective coating for reflecting heat energy toward the smoking substitute consumable.

The corresponding heat-reflective coating can further enhance the barrier functionality of the insulating shield that insulates the inside of the shield from the outside of the shield.

According to a further embodiment of the present disclosure, the smoking substitute device may further include a second heating element, wherein the second heating element may be arranged between the smoking substitute consumable and the insulating shield for heating the outer surface of the smoking substitute consumable At least part of.

With the corresponding arrangement, it is possible to heat from both sides (ie heating from the inside by the first heating element and heating from the outside by the second heating element) instead of smoking consumables. This can help heat the tobacco material in the smoking replacement consumable more evenly. The second heating element may form an integral part of the insulating shield, or may be arranged as two separate devices, which may be removably separated from each other from the smoking replacement device.

According to another embodiment of the present disclosure, the heating element may be a rod-shaped heating element, and the length of the insulating shield may be at least the length of the rod-shaped heating element.

Therefore, the insulating shield can substantially completely surround the heating elements arranged in the interior and the cavity of the insulating shield, respectively. The length of the insulating shield can therefore correspond to the length of the heating element.

According to a further embodiment of the present disclosure, the insulating shield may include holes for allowing access to the inside of the cavity.

In detail, the hole may allow access to the inside of the cavity to allow access to the heating element. By means of the inlet and outlet, and especially with the use of appropriate tools, the heating element can be cleaned. For example, with the elongated cleaning element, the heating element can be cleaned by removing the inlet and outlet or old tobacco material stuck to the heating element after removing the smoking substitute consumable.

According to a further embodiment of the present disclosure, the hole may be located at the distal end relative to the outward facing opening of the cavity.

In other words, the opening allows the smoking replacement consumable to be inserted into the cavity while the hole is arranged at the distal end (for example at the base of the cavity near the exposed heating element) relative to the outward facing opening. In detail, in the case where the length of the insulating shield is longer (especially substantially longer) compared to the length of the heating element, arranging the hole at the bottom of the cavity will allow easy cleaning for cleaning purposes. Take heating element.

According to a further embodiment of the present invention, the size of the hole may be arranged so that the user of the smoking alternative device may not physically contact the heating element, especially where the size of the hole on the shield is adjusted to prevent fingers from entering and exiting.

In other words, the size of the hole can be adjusted to accommodate the cleaning element while being too small to allow the user to touch the heating element with their hands (especially with fingers), for example. By providing holes that adjust the size accordingly, it is possible to prevent the user from being hurt by the heating element that may still be hot.

According to a further embodiment of the present disclosure, the smoking substitute device may be a heat-not-burn smoking substitute device. The skilled person will understand that the features or parameters described with respect to any of the above aspects can be applied to any other aspects except where mutually exclusive. And, except where mutually exclusive, any feature or parameter described herein can be applied to any aspect and/or combined with any other feature or parameter described herein.

FIG. 1 shows a view of an exemplary embodiment of a smoking substitute device 10 (here, exemplarily an HNB device 10).

The HNB device 10 includes a rod-shaped heating element 12 that protrudes into a cavity 14 in the main body 16 of the device 10. The smoking substitute consumable 20 can be inserted into the cavity 14 of the main body 12 of the device 10, so that the heating rod 12 penetrates the smoke forming substrate (such as tobacco material) in an outer part, and the other part is, for example, the lower part of the smoking substitute consumable 20 Part, the other part is located at the distal end with respect to the outward facing opening 42 of the cavity 14. For example, heating of the reconstituted tobacco in the aerosol-forming substrate is achieved by powering the heating element 12 with a power source 18 (for example, a rechargeable battery 18 incorporated in the smoking replacement device 10). As the tobacco heats up, the moisture and volatile compounds (such as nicotine) in the tobacco and possibly humectants are released as vapors and are entrained in the air stream created by the user's inhalation.

The heating of the tobacco by the heating element 12 can be activated by the user pressing the actuator 26 (here, exemplarily the activation switch 26) on the side surface of the main body 16 of the smoking alternative device 10. The display element 28 (exemplarily a plurality of LEDs here) is arranged near the start switch 26 on the side surface of the main body 16.

In other words, the insulating shield provides a thermal barrier between the heated smoking alternative consumable 20 and the exterior of the smoking alternative device 10, so that the user of the smoking alternative device 10 can not contact the heated smoking alternative consumable 20, or in case of isolation The area of the shield is indeed touched by the user, and the user only receives moderate heat that does not cause harm.

The shield 38 includes a hole 40 which is arranged at the distal end with respect to the outwardly facing opening 42 of the cavity 14 and is therefore arranged near the heating element 12. The holes may be used to clean the heating element 12, for example, by inserting a suitable cleaning element into the hole 40 to wipe off excess tobacco material or residual tobacco material from the heating element 12. At the same time, the hole 40 is small enough and far enough relative to the heating element 12 so that the user cannot touch or touch the heating element 12 through the hole 40.

In order to operate the smoking substitute device 10, a control element 26 (such as a button or a start switch) is provided. The control element may further include a display element 28 for displaying operations or other information to the user of the smoking substitute device 10.

A memory 34 is provided for storing control instructions for the control unit 32 or the microprocessor, for example. Preferably, the memory 34 is provided as a non-volatile memory. The smoking substitute device 10 may further include a display element 28, which may be implemented as a single or multiple LEDs or organic LEDs. The LED may be adapted to display different colors according to instructions from the control unit 32 and the memory 34, thereby depicting different operating modes of the smoking replacement device 10 with different colors, or generally involving the user operating the smoking replacement device 10 Different information. A control element 26 (such as an actuator or a start switch) is provided, with this control element, the smoking substitute device can be turned on and off, the operation can be started, and/or the operation mode can be set.

Further, an electrical interface 30 or a charging connector 30 is provided, which may be incorporated in the main body 16 and may include one or more electrical contacts. The electrical interface 30 may be located in a hole in the end section of the main body 16 and preferably at the bottom of this hole. The electrical interface 30 may be adapted to be coupled with an external charging station to receive power for charging the power source 18. Alternatively, the electrical interface 30 can be implemented as a charging connector 30, which can be a USB or lightning connection. Preferably, the charging connector 30 is implemented as a USB-C connector, which is an example of a symmetrical connector.
