Abstract

The presented smoking system is heated up by a passing current through a range of heating elements and a replaceable cigarette fixed into a burner, at the same time, tobacco odours and other components taking a form of vapours and aerosols created in the heating process are supplied to smoker. The cigarette and burner are made so that air gets into the smoking system through the cigarette sides. Such a supply of air flow enables it to supply odours and aerosol to the smoker and reduces condensation in the smoking system of vapours and aerosols that are present in the heating device.

Description

The present invention relates to smoking systems using a cigarette and a torch and to methods of making them.

An electric smoking device is described in our U.S. Pat. 5060671. The smoking device disclosed in this patent operates a series of electrical heating elements. The tobacco flavoring or tobacco derived material is attached to each heating element. Such a replaceable odor supply device is connected to an electrical power source, such as a battery or a condenser, through an electrical control device for activating the heating elements, for drawing air through the device, or for loss within the device. The control device is designed so that at least one, but not all, of the heating elements are actuated by each fixed number of cigarette strokes, during which the set amount of tobacco flavoring is released. This fragrant tobacco reaction, such as an aerosol with tobacco odors, is delivered to the smoker. The control device also prevents the heating element from being actuated more than once, thus preventing the fragrance from overheating. In these devices, the heating element is removed together with the contents of the tobacco flavoring used. Also, the connections (contacts) of the battery and the heating elements must remain reliable by constantly replacing the heating device and disconnecting them from the contacts.

U.S. Application No. 07/666926, filed March 1991 March 11 and now having no. No. 08/012799, issued Feb. 2, 1993, discloses a smoking apparatus incorporating reusable heating elements and a replacement part for generating tobacco odors. The replacement part is preferably composed of fragrance segments and filter segments joined by reinforced paper or other material. The disadvantages of such a device are related to the reusable heating elements, as the aerosol condenses on the surfaces of these elements and other non-replaceable structural elements of the device.

The present invention seeks to alleviate the above problems.

The invention and its various aspects are defined by independent claims which will be discussed later.

The smoking systems implementing the present invention, which use a cigarette and a torch, allow for improved odor delivery. An advantage of the smoking system implementing the present invention is that the heating elements in the burner are reusable and the volume of replaceable parts is minimal.

The system also has the advantage of reducing the possibility of aerosol condensation on heating elements and other structural components of the burner.

An advantage of the smoking device implemented according to the present invention is that the technological process of production is simpler, lower costs are required, and the speed of serial production is higher.

In one embodiment of the invention, the cigarette is placed in a smoking system with heating means that provides a smoky tobacco response to the smoker. A cigarette consists of a carrier material having first and second ends extending along opposite sides of the cigarette and having first and second surfaces. The first surface delimits the cavity between the first and second ends, and the second surface delimits the area adjacent to the heating means. The tobacco flavoring is applied to the first surface of the carrier material. By heating the tobacco flavoring with heating means, it produces in the cavity a fragrant tobacco reaction which is fed to the smoker. Air can enter the cavity through the carrier and the tobacco flavoring.

In another embodiment of the invention, the burner is configured so that it and the replacement cigarette can be used in a smoking system which supplies a fragrant tobacco reaction.

The burner consists of a housing for the heating device through which a replaceable cigarette is inserted at the front end; a plurality of heating elements disposed within the heating device body having a surface adjacent to a portion of the surface of the cigarette through which the lateral flow of air passes; and, also, means for activating one or more of the plurality of heating elements such that a predetermined odorous tobacco response is generated in the cigarette. Lateral directional airflow occurs when the smoker draws air through a cigarette inserted into the torch.

In another embodiment, the present invention provides a smoking system for delivering a smoky tobacco response to a smoker. The system individually activates the heating means so that a custom-sized, fragrant tobacco response is generated in the cigarette cavity.

In yet another aspect, the present invention provides heating elements that are used to deliver a fragrant tobacco reaction. The heating element comprises a front and a rear end, with a series of serpantine-shaped zones increasing the resistance of the heating elements. The heater elELT 3859 B is made of a resistive material so that the first and second surfaces of the heater are oriented in the plane, respectively, with an overall length of L, a width of W and a weight of T. The effective length of the heater is greater than L the effective cross-sectional area of the heating element is less than WT

In yet another aspect, the present invention provides a method of manufacturing an integrated heating device for use in delivering a smokable tobacco reaction to a smoker.

According to this method, the plate of resistive material is cut by forming a series of heating elements connected at one end to one another. Thereafter, this workpiece is formed into a cylindrical shape.

The smoking system 21 implemented in accordance with the present invention is illustrated in FIG. 1 and FIG. 2. The smoking system comprises a cigarette 23 and a reusable burner 25. The cigarette is designed to be inserted or withdrawn from the opening 27 in the front portion 29 of the burner 25. The smoking system is used in a manner similar to a conventional cigarette. The citrus 23 is removed from the burner 25 after one or more cycles of engagement. The burner 25 is removed after a greater number of pulling cycles. The burner 25 comprises a housing 31 consisting of a front 33 and a rear 35. The power source 37 for supplying power to the heating elements that light up the cigarette 23 is preferably mounted at the rear of the torch 35. Preferably, the rear portion 35 can be easily opened and closed and secured using screws or clips to facilitate power source replacement. Also, it is preferable for the front part 33 to be fitted with heating elements and an electric control device which are connected to a power source 37 located at the rear part 35. The front part 33 is easily connected to the rear part 35 by means of clips or couplings. The housing 31 is made of a hard, heat-resistant material. The preferred materials may be metals or, more preferably, polymeric materials. The body 31 is designed to be comfortable to hold in the hand of a smoker and, in the best embodiment of the present invention, has a body size of 10.7 cm x 3.8 cm x 1.5 cm.

The energy source 37 supplies energy to the heating elements 43 of the cigarette 23. Preferably, the energy source used can be replaced or charged and a capacitor or, better still, a battery can be used. In the best embodiment of the present invention, a removable and rechargeable battery consisting of four cadmium-nickel cells connected in series and having a voltage of approximately 4.8 V to 5.6 V is used as an energy source. 21 characteristics of the system, and more specifically the parameters of the heating elements. U.S. Pat. No. 5,144,962 discloses several types of energy sources that may be used in the smoking system of the present invention. These are power sources that use rechargeable batteries, fast-discharging capacitor power sources that are also charged by batteries.

A cylindrical heater 39 for heating and holding the cigarette 23 in the burner 25 and an electric control device 41 for supplying a predetermined amount of energy from the power source 37 to the heating elements (not shown in Figs. 1 and 2) in the heater. In the best embodiment of the present invention, the heating device comprises eight heating elements 43 arranged in radial directions, see Figs. 3A, and, under the control of the device 41, receive energy separately from the source 37. The control device 41 generates eight hot zones about the cigarette 23 and, thus, can generate eight fragrant tobacco reactions. Since the other number of heating elements 43 is not used, eight heating elements are most suitable, primarily because up to eight fragrant tobacco reactions can be formed in a conventional cigarette, and also, binary code devices can easily be used to control the heating elements.

The control unit 41 is preferably actuated by an air-gauge excited sensor 45 shown in FIG. 2, which responds to a change in air pressure or a change in air velocity when the smoker draws air through the cigarette 23. The air-trigger sensor 45 is preferably mounted on the front portion 33 of the burner 25 and communicates with the space inside the heater 39 and the cigarette 23 through a passageway 47 passing through the heater gasket 49 and base 50 and, if necessary, the air-trigger sensor tube (not shown). An air-gust sensing sensor 45, which can be used in smoking systems 21, is described in U.S. Pat. The present invention discloses a sensor, such as a Model 163PC01D35 silicon sensor manufactured by Honeywell Ine., Of Microswitch, Ereeport, III, that activates one of the heating elements upon pressure change when a smoker draws air through a cigarette 23. It has been found that airflow recorders incorporating the principles of instantaneous anemometry may be used to detect changes in the flow of the air by triggering an appropriate heating element.

An indicator 51 indicating the number of tobacco responses remaining in the cigarette 23 which is inserted into the burner 25 is located outside the burner 25, preferably at the front 33. The most suitable indicator is a seven-segment liquid crystal display (LCD). In this embodiment, the indicator will reflect the number 8 when the light beam emitted by the light sensor 53 shown in FIG. 2, will be reflected from the newly inserted cigarette 23 and will be defective by the light sensor 53. The light sensor 53 is preferably mounted in the cavity 55 located in the spacer 49 and the base 50 of the heating device, as illustrated in FIG. 3A. The light sensor 53 sends a signal to the circuit 41 which, when processed, supplies a signal to the indicator 51. The reflection of the number 8 in the indicator 51 indicates that smoking a cigarette can produce an odorous tobacco reaction 8 times, i.e. no heating element has yet been activated and the new cigarette has not been heated. After the cigarette 23 is pulled eight times, the indicator shows the number 0. When the cigarette 23 is removed from the burner 25, the light sensor 53 does not detect the cigarette 23 and the indicator 51 is turned off. The light sensor 53 emits a modulated light stream and such emitting of the light beam reduces unnecessary waste of power from source 37. Most suitable for use in the smoking system 21 is a light sensor 53 OPR 5005 manufactured by OPTEK Technology Ine., 1215 West Crosby Road, Carrollton Texas 75006.

As a possible alternative to the above-mentioned light sensor 53, there may be a mechanical switch (not shown) detecting the presence or absence of a cigarette and a reset button (not shown) used to reset the control device 41 when the new cigarette is inserted into the burner 25, t. i.e., to set the indicator 51 to a state of 8, and so on. Power sources, control device, air-triggered sensor and indicator that may be used in the smoking system 21 of the present invention are described in U.S. Pat. 5060671, which is incorporated herein by reference. The passage channel 47 and the cavity 55 located in the spacer 49 and the base 50 of the heating device are airtight during smoking. A preferred cigarette 23 which can be used in the smoking system 21 is illustrated in FIG. 4A and FIG. 4B, however, the cigarette 23 may be in a different form and may be generated by heating it with heating elements 43 to provide an odorizing tobacco reaction which is delivered to the smoker. The cigarette 23 comprises a tobacco layer 57 formed on a holder 59 which holds the flavoring tobacco material 61, preferably made of tobacco. The tobacco layer 57 is screwed into a tube and is supported by a cylindrical return filter 63 at one end and a cylindrical first open pass filter 65 at the opposite end. The first open pass filter 65 is in the form of an open tube having a longitudinal passage 67 extending through the center of the first open pass filter and providing low resistance to incoming air.

If necessary, the cigarette tobacco layer 57 is rolled onto paper 69. The tobacco layer is rolled onto lightweight paper, preferably wrapped in tobacco products, or into a paper made of tobacco, which gives the tobacco an aromatic tobacco reaction. The concentrated or diluted extract can be incorporated into cigarette rolling paper 69. The paper used for rolling cigarettes has a low weight and small rolling diameter, and is sufficiently robust to be machine-processed. Paper made from tobacco is characterized by the following sizes: its weight at 60% relative humidity is 20-25 g / m ² and the minimum air permeability is 0-25 CORESTA (defined as the amount of air measured in cubic centimeters which passes through one square centimeter, ie one sheet of paper per minute at a feed air pressure of one kPa), a strength limit greater than 2000 grams / 27 mm wide (1 inch / min), curvilinear 1.3-1.5 mil, CaCO ₃ content less than 5%, citrate content 0%. More than 75% by weight of the paper used for rolling a cigarette is tobacco material (obtained from tobacco dust, stalks or mixtures thereof). The amount of flax fibers in the paper shall not exceed what is necessary to achieve the desired strength. The cigarette rolling paper 69 may be regular linen fiber paper having a weight of 1520 g / m or similar. The binder used is citrine pectin in a quantity of less than or equal to 1% in paper. The amount of glycerin in the paper is not greater than is necessary to obtain a paper so rigid that it resembles paper commonly used in the manufacture of cigarettes.

The cigarette 23 also preferably comprises a cylindrical bump filter 71, which is a conventional RTD filter, and a cylindrical second open pass filter 73. The bump filter 71 and the second open pass filter are bonded to one another by reinforced paper 75. Reinforced the paper 75 is extended beyond the second end of the open pass filter 73 and is glued to the paper 69, thereby attaching the end of the first open pass filter 65 to the end of the second open pass filter 73. Similar to the first open transition filter 65, the second open transition filter 73 has a longitudinal channel formed through the filter centers. The return filter 63 and the first open pass filter 65 and the tobacco layer 57 form a cavity 79 inside the cigarette.

Preferably, the longitudinal inside diameter of the channel 77 is larger than the inside diameter of the longitudinal channel 67 of the open filter 65. Preferably, the longitudinal channel 67 has an inside diameter of 2 to 6 mm. The differences in the internal diameters of the channels 64 and 77 facilitate the formation of turbulence or the mixing of the aerosol generated by heating the flavoring tobacco material and the air entrained in the cigarette 23 during the intake of the cigarette, thereby affecting the composition of the resulting minimizing the effect of the bump filter on the mixed aerosol. The fragrant tobacco reaction is obtained by heating the tobacco fragrance 61 and is understood to be in vapor form in the cavity 79 and turns into a visible aerosol mixed with air in channel 77. Also, in addition to the first open pass filter 65 described above with other longitudinal channel 67 the tobacco vapor / air mixture is formed by supplying air to the open pass filter through a series of small openings, the first open-pass filter may be honeycomb or metal plate with a plurality of holes.

Air is drawn into the cigarette 23 mainly through the tobacco layer 57 and the cigarette wrapping paper 69, transversely or radially, rather than longitudinally through the return filter 63. As will be explained below, sometimes during the reaction of the first cigarette 23 it is desirable Allow airflow to pass through the return filter, thereby reducing cigarette pull resistance (RTD). It is understood that by longitudinally entraining air through a cigarette 23 formed by heating the heating elements 43 disposed radially about the tobacco layer 57, the aerosol is not completely withdrawn from the cavity 79. The fragrant tobacco response is best obtained by specifying the characteristics and structure of the tobacco layer 57 43 the amount of energy emitted. Thus, the portion of airflow through the cigarette 23 extending longitudinally through the return filter 63 during smoking is minimal and only functions during the first stroke. Also, the return filter 63, upon heating of the tobacco fragrance 61, minimizes the reverse flow of aerosol from the cavity 79, thus greatly reducing the possibility of damaging the components of the burner 25 from the cigarette 23 by the return aerosol.

The holder 59 holds the tobacco fragrance 61, separates the tobacco flavor from the heating elements 43, and transmits heat from the heating elements to the flavoring! tobacco material and keeps the cigarette intact after smoking.

Preferably, a carbon fiber mesh having high stability is used as a carrier 59. Such holders are described in more detail in U.S. Patent Application Ser. No. 1992/943747 September 11 and the present invention. This net has a thickness of about 0.05 mm to about 0.11 mm and is made up of non-woven carbon fiber with a weight of 6 g / m ² to 12 g / m ² and a fiber diameter of 7 mkm. up to 30 mkm. The length of the fiber fibers must be such that the net can withstand the stresses arising during processing. It is good to use a binder suitable for use in electrical smoking devices (i.e., having acceptable properties) in the net.

Also, a lightweight metal mesh with perforations or perforated metal foil can be used as a carrier 59. For example, a mesh net of 5 g / m to 15 g / m and a wire diameter of 0.038 mm (about 1.5 mils) to about 0.076 mm (about 0.25 mils) can be used. In another embodiment, the mesh is formed from a foil having a weight of 0.0064 mm (about 0.25 mils), for example, aluminum, with perforated holes having a diameter of 0.3 mm to 0.5 mm that reduce the weight of the foil by about 30% to about 50%, respectively.

Preferably, the perforated holes in the foil are arranged in a chess-like or uneven manner (i.e., continuous strips of holes are not formed) and thereby reduce heat transfer from the area with tobacco flavoring 61 to the surrounding areas. Such metal mesh and perforated foil screens on a cigarette 23 are mounted in various ways, for example: (1) by pouring a liquid mass of tobacco flavoring onto a tape and mesh or perforated foil holder as wet stains prior to drying, and (2) by laminating a mesh or foil holder. a sheet of tobacco flavoring or a paste. Since the metal holder may have electrically shortened parts of the heating element or different heating elements 43 in the cigarette 23, such holder 53 must not come into contact with the heating elements 43. When using metal holders, the metal holder 53 and the heating elements 43 are insulated with a suitable binder or paper 69.

The process for forming the tobacco layer 57 in the embodiment is similar to the process for making paper. During this process, the tobacco cuttings are soaked in water. Dissolved materials are used later in the coating step. The resulting tobacco fiber is used to make the backing mat. Carbon fibers are dispersed in water containing sodium alliginate. Any other hydrocolloid which does not alter the reaction of the odorous tobacco, is water soluble and has the appropriate molecular weight to give the tobacco layer 57 sufficient strength may be added in place of sodium alligate. This dispersion is mixed with the solution soaked in the tobacco or with unnecessary odors. The resulting wet mixture is then spread into a layer and further undergoes the remaining processing operations of a conventional papermaking machine to form a backing layer. One side of the backing layer is coated with materials released from the tobacco cuttings during soaking, preferably a conventional, reverse shaft cover, followed by a drum or an American dryer. The tobacco release / tobacco dust ratio can be varied from 1: 1 to 1:20. The liquid mass can also be pressed onto the base mesh. Alternatively, the coating step may be realized separately (not in a conveyor line). During or after the coating step, the usual smells in the cigarette industry are added. The adhesion of the liquid mass is increased by the addition of pectin or other hydrocolloids, preferably from 0.1 to 2%.

With all types of holders 59, the tobacco fragrance 61 that emits odors when heated is adhered to the inner surface of the holder. Such materials, which adhere to the inner surface of the holder, may be in the form of plates, foam, dried liquid mass sprayed on the holder, preferably but not necessarily consisting of tobacco or tobacco-derived materials. These materials are described in more detail in U.S. Application Ser. 07/943747.

The tobacco layer 57 is treated with a humectant of 0.5 to 10%, for example glycerol or propylene glycol. The humectant facilitates the formation of a visible aerosol by acting as an aerosol agent. By pulling a cigarette, the smoker evaporates the aerosol, which contains a fragrant tobacco reaction and a humectant. The humectant condenses in the atmosphere to produce smoke in the normal reaction of a cigarette.

Since the tobacco flavoring 61 of the present invention is affixed to the surface of the holder 59, the characteristics of the supplied odors may be varied in space by selectively changing the magnitude of the supplied reaction and the odor intensity at the time of each cigarette pull. For example, the first heating element may have one amount of the first tobacco flavor and the next heating element may contain another amount of the other tobacco flavor. Thus, the smoky tobacco response given to the smoker can be effectively altered by forming an abnormal distribution of the flavoring tobacco material on the surface of the holder. For example, the smoker may rotate the cigarette 23 inserted into the burner 25 with respect to the constant heating element so that the heating element heats a portion of the heterogeneous tobacco flavor.

In addition, according to the present invention, the fragrant tobacco reaction can be selectively altered by controlling the amount of energy supplied to the heating elements 43. For example, if the first heating element 43 is supplied with greater energy (e.g., 20 joules) than the second heating element 43 (e.g., 17 joules), the first heating element will heat to a higher temperature and the first element will generate a more fragrant tobacco reaction than the second. In this way, the magnitude of the fragrant tobacco response can be selectively controlled by varying the amount of energy at the time each cigarette is pulled.

Preferably, the cigarette 23 is made in a constant diameter of approximately 7.5 mm to 8.5 mm and coincides with the diameter of a regular cigarette for a smoker. In the preferred embodiment of the present invention, the cigarette 23 has a length of 58 mm, which makes it possible to use a conventional cigarette rolling machine. The overall composite length of the muffler filter 71 and the second open transition filter 73 is 30 mm in the best embodiment. The reinforced paper 75 protrudes 5 mm beyond the second end of the open transition filter 73 and the tobacco layer. The tobacco layer 57 has a length of 28 mm in this embodiment. One end of the tobacco layer rests on a return filter 63 which is 7 mm long. The cavity 79, bounded by the cylindrical tobacco layer 57, the return filter 63 and the first open pass filter 65, is preferably 14 mm long.

When the cigarette 23 is inserted into the opening 27 at the end 28 of the first portion 25 of the torch, it engages or abuts the inner surface 81 of the gasket 49 of the heating device 39 as shown in FIG. 3A, adjacent to a passageway 47 connected to a gust-sensing sensor 45 and a recess 55 housing a light sensor 53. In this position, the cigarette 23 cavity 79 is closest to the heating members 43 and other cigarette parts such as the second open pass filter 73 and the muffler filter 71 protrudes outside the burner 25. The heating elements 43 are best disposed radially, thereby securing the position of the cigarette 23 with respect to the heating elements when they provide the heat to the tobacco layer 57 directly or through the paper 69 on which the 3801 B tank layer is twisted. Thus, it is best for the cigarette 23 to be able to compress and thereby reduce the pressure of the heating elements 43 on the sides of the cigarette.

The air 23 enters the cigarette through various paths. For example, in the cigarette embodiment shown in FIG. 4A and FIG. 4B, the paper 69 on which the cigarette is rolled and the tobacco layer 57 are permeable to the air, providing the required retraction resistance (RTD) such that air is drawn into the cavity 79 transversely or radially or through the paper 69 and tobacco As mentioned above, the return filter 63 can be used to obtain longitudinal movement of air through the cavity 79.

If necessary, the transverse air flow into cavity 79 is increased by making a series of apertures (not shown) on paper 69 and tobacco layer 57, in one or more areas adjacent to cavity 79. Such apertures have been found to improve the fragrant tobacco response and facilitate aerosol formation. The apertures through the tobacco layer 57 are shown at a density such that 1-2 mm ² is a single aperture and has a diameter of 0.4 to 0.7 mm. The porosity of such a layer is from 100 to 500 CORESTA. Paper 69 has a throughput of 100 to 1000 CORESTA. It will be appreciated that other smoking characteristics may be formed or densified to obtain other smoking characteristics, such as different pull resistance.

The flow of air into the cavity 79 in the transverse direction may be facilitated by the formation of curls through paper 69 and tobacco 57 at the same locations. In the manufacture of such a cigarette 23 with apertures, the paper 69 and the tobacco layer 57 are bonded together and punched, or individually, the paper and tobacco layer are apertured and then folded so that the apertures overlap or overlap.

The best embodiment of the heating device 39 is shown in Figs. 3A and FIG. 3B. A view of a modified heating device 39A using a homogeneous spacer and base particle 49A is shown in FIG. 5. In the heating device 39A, the member 49A replaces the spacer 49 and base 50 which are provided in the heating device 39 shown in FIG. 3A. All functions performed by the heating device, such as making the cigarette space 23, heating the cigarette with heating elements, will of course be realized other than as illustrated in FIG. 3A, FIG. 3B and FIG. 5 design heating device.

In interpreting Figs. 3A and FIG. 3B, the heating device 39 is mounted in the cigarette inlet 27 in the burner 25. The cigarette 23 is inserted into the device such that the return filter 63 is inserted into the burner port 27 whose cylindrical shape in the heating device 39 is defined by an annular cap 83 a cigarette 23 is inserted, optional, cylindrical protective nozzle 85, cylindrical air channel nozzle 87, heating unit 89, combining heating elements 43, electrical outlet or common outlet unit 91 for supplying current to heating elements 43 as a common terminal, and spacer 49. The base surface 81 of the spacer 49 stops the cigarette 23 in the required position in the heating device 39 when the heating elements 43 are located adjacent the cavity 79 in the cigarette 23. The heating nozzle 39A shown in FIG. 5, the base surface 81A stops the cigarette 23 when it is positioned in the required position with respect to the heating elements.

All parts of the heater 39 are mounted inside it and the device 39 is secured by pressing it against the housing 31 at the front of the burner 25 33. The leading edge 93 of the cap 83 is slightly protruding outward from the front 29 of the burner 25 and is preferably its inside edge is sloping or rounded. This facilitates the insertion of the cigarette 23 into the heating device 39. The heating elements 43 of the heating unit 89 and the rod-shaped outlet 95 are mounted on the outer surface of the spacer 49 by a ring 99 and held in place by friction. To connect the heating device to the control device 41 and power source 37, the ends 101 of the heating elements 43, and preferably the ends of the two leads 95 with the leads 104, are reliably connected by welding, and 104 projecting from the outer surface 105 as shown in FIG. 3B. Outlets 104 in base 50 Mounted to prevent air from passing through holes 107. Outlets 104 are connected to respective sockets (not shown) to form a support for the heating device 39 in the burner 25, and the printed circuit board conductors connect the sockets to the various control circuit elements. The two outlets 95 provide additional rigidity to the inlet assembly 91. The passageway 47, located in the spacer 49 and the base 50, communicates with the air-trigger sensor 45 and the light sensor 53 for detecting the presence or absence of a cigarette 23 in the burner 25.

In a similar manner, the heating device 39A shown in FIG. 5. The terminals of the heating elements 43 of the heating unit 89 and the outlet assembly 91 are secured to the outer surface 97 of the part 49A by a ring 99 and held in place by friction. The rear portions 101 of the heating elements 43 and the rear portions of preferably two outlets 95 extend from the outer surface 105 of the portion 49A and may be connected to the control means 41 or power source 37.

The end 109 of the part 49A, which is preferably formed as a flange, has at least two tongues or notches through which the outer ends 95A of the two outlets 95 extend. The other two terminals 95 provide additional rigidity to the outlet assembly 91. The rear portions 101 of the heating members 43 may conform to the flange shape of the end 109 and protrude from the surface 50A of the base 50 with the flange outside the outer edge 111. The permeability channel 47 in the part 49A communicates with the air-gust sensing sensor 45 and the light sensor 53 detecting the presence or absence of a cigarette 23 in the burner 25.

The heating unit 89 shown in FIG. 3A, FIG. 5 and FIG. 6 is best made by laser cutting a sheet of a so-called super alloy with high mechanical strength and surface resistance at high temperatures. The sheet is cut or stamped and is preferably cut with a CO ₂ laser to form a common blank 115 of the heating unit 89. In the blank 115 of the heating unit 89, the heating elements 43 are connected to one another at the back 101 and 117 respectively. connects the bar at the front and back. Rear strip 117 and side strip 123 to heating unit 89 are incomplete to facilitate workpiece processing.

In the formed blank 115, each heating element has a wide portion 125 which is adjacent to the tobacco layer 57 in the heating unit 89 and a narrow portion 127 is used to form connections to the electrical control device 41. If necessary, each heating element 43 has proximal rear portions 101 having extensions (contact areas) 129 to facilitate connection to terminals 104 by welding, or securing sockets (not shown) to electrical control unit 41. Further processing 115 is performed, preferably by laser cutting, and forming a serpantine-like member 131 of the wide portion 125 of the heating element shown in FIG. 6 and FIG. 8. Of course, the serpentine element 131 may also be cut during the production of the workpiece.

The cut or stamped workpiece is polished, preferably by electrolysis, rounding the edges of the heating elements 43. The rounded edges of the heating elements 43 facilitate insertion of the cigarette 23 into the burner 25. The cut or stamped workpiece is bent to give it a cylindrical shape of the heating device. The rear and side strips 117 and 123, respectively, are cut and the front edges 133 of the skin contact 121 are welded to form a separate or integral heating assembly as shown in FIG. 6th

The heating assembly 89 may also be manufactured in another manner. For example, in one embodiment of the heating assembly 89, the sheet is folded into a ring and then the individual heating elements 43 are cut, which are spot-welded to the ring forming the general connection of the heating elements as well as mechanically reinforcing the heating elements. In the above embodiment, this is done by the front portion 121. Also, the front portion of the heating assembly 89 may be welded or attached to a hole size ring (not shown) having an inside diameter nearly equal to the diameter of the cigarette 23. This ring provides the heater assembly 89 with additional strength and ease of service.

The output node 91 is shown in FIG. 9 and is manufactured by one of the methods used in the manufacture of the heating unit as described above. As with the fabrication assembly 89, the ribbon-shaped elements 135 of the front assembly 135 and the individual assembly 95 are cut from a thick sheet of electrically conductive material, rolled and welded to form a cylindrical article. The outlet assembly 91 is preferably constructed such that its internal diameter is approximately equal to the external diameter of the heating assembly 89. Thus, the front portion of the heating assembly 89 may be inserted into the front portion 135 of the outlet assembly 91 and be joined to one another, preferably by welding, so that the four terminals 95 (only two of which are electrically connected to the terminals 104 projecting through the base 50) are arranged in the radial directions and form angles of 22.5 ° with adjacent heating elements 43, and their connection terminals protrude through the base 50.

All embodiments of the burner 25 are designed to provide the smoker, under normal conditions, with all the ingredients released during the smoking of the fragrant tobacco.

It has been found that a smoker is provided with 5 to 13 mg of aerosol per eight cigarette pulls, preferably 7 to 10 mg, with each cigarette retraction being 35 ml in volume and lasting two seconds. It has also been found that in order to produce such a reaction, the heating elements must heat up to about 200 ° C to 900 ° C, with good heat exchange with the cigarette 23. Also, the heating elements must yield about 5 to 40 joules energy, preferably 10 to 25 joules, and even more preferably 15 joules 3859 B. If the heating elements 43 are inclined inwardly, the heat emitted to the cigarette 23 and, better, the energy emitted may be reduced.

The heating elements 43 emitting said energy have the following characteristics: the core has a cross-sectional area of 3 mm to 2.5 mm and a resistance of 0.5 to 3 ohms. The preferred resistance of the heating elements 43 is between 0.8 and 2.1 ohms. It is understood that the resistance of the heating elements is partly determined by the parameters of the power source 37, which supplies the electricity required to heat the heating elements 43. For example, heating elements having the above-mentioned resistances are utilized in a device that uses four nickel-cadmium battery cells as a power source, which, when connected in series, provide a voltage of 4.8 to 5.8 V. In other embodiments, batteries with six or eight such cells shall be connected in series, and the resistance of the heating elements shall be between 3 and 5 ohms or between 5 and 7 ohms, respectively.

The material of which the heating elements are made shall be selected on the basis of its ability to withstand multiple cycles of at least 1800 turns on and off and to remain intact. The heating device 39 is best replaced separately without replacing the burner 25, which further comprises an electric power source and a control device capable of making more than 3,600 switches. The material from which the heating elements are made is selected on the basis of its oxidative properties and the overall passivity of the material which ensures that the heating elements do not oxidize or otherwise react with the cigarette 23 at all possible temperatures. If desired, the heating elements may be encapsulated in an inert, heat-conducting material, such as a suitable ceramic material, which further reduces their oxidation and reactions with the cigarette 23. Based on these criteria, materials used in electrical heating devices may consist of a semiconductor paste ( ie silica paste), carbon, graphite, stainless steel, tantalum, metal ceramic and metal alloys such as nickel-chromium and iron alloys. The silicon semiconductor material is doped with phosphorus in a concentration of

5 * 10 to 5 * 10 impurities / cm, which gives ~ 2 material having a relative impedance of from 1 * 10 ohm / cm to 1 * 10 ohm / cm as described in U.S. Patent Application Ser. 07/943505. Silicon carbon aluminum or silicon carbon titanium metal ceramic matrices may be used. Intermetallic compounds such as nickel aluminide or iron aluminide are used to reduce oxidation.

However, it is best that the electric heating elements are made of a heat-resistant alloy which is mechanically strong and does not decay at high temperatures. Preferably, the heating elements are made of a material that exhibits high rigidity and surface stability at operating temperatures close to the melting point temperature (about 80%). Such alloys have been referred to as super alloys and are generally made of nickel, iron or cobalt. A suitable material in the super alloy from which the heating element 43 is made is aluminum, which prevents the super alloy from oxidizing. Such materials are available from Haynes International Ine., Kohomo, Indiana as an alloy of Haynes 214. This material includes, among other things, about 75% nickel, about 16% chromium, about 4.5% aluminum, and about 3% iron.

As described above, each heating element 43 of the heating unit 89 has a serpentine portion 131 consisting of a series of sequentially connected curved S-shaped zones increasing the effective resistance of the heating element. In the serpentine portion 131 of the heating element 43, a zone of increased impedance is formed without increasing the overall length of the heating element or reducing its cross-sectional area. A heating element 43 having an impedance of about 0.5 to about 3 ohms and a serpentine length such that it can be mounted in the heating devices 39 and 39A of FIG. 3 and FIG. 5, is preferably composed of N interconnected S-shaped zones, where N can be from 3 to 12, but is preferably when N is from 6 to 10.

If the serpentine portion 131 of the heating element 43 shown in FIG. 8, was first cut as a broad section 125 FIG. 7 having a width W1, length -L1, and thickness T1, the impedance from one end 125 'to the other end 125' of the opposite end is described by the equation:

p · L1 R = W1 · T where p is the specific resistance of the material used. When the serpentine part 131 is formed, its resistance increases as the effective length of the heating element 43 increases and the cross-sectional area decreases. For example, in the heating element 43 having the serpentine portion 131, the current in the heating element will flow along the trajectory P. The effective electrical length of the trajectory P is 9 or 10 W1 (i.e., nearly five turns of the serpentine portion of the heating element). In addition, the cross-sectional area decreases from Wl T to W2. Thus, according to the present invention, the increase in the length of the heating element 43 and the reduction in the cross-sectional area increase the total resistance of the heating element 43 to electric current, since the impedance to electric current is proportional to the length of the conductor.

Thus, the formation of the serpentine portion 131 in the heating element 43 allows a smaller impedance material to be applied to the set impedance, while the area occupied by the heating element remains within the target size, for example from 3 mm to 25 mm. These features of the present invention provide at least three advantages.

The first, resistive heating element 43 is formed of a rectangular sheet which, if the heating element 43 were linear, would have a greater length. This makes it possible to produce a compact heater 39 and a cheaper burner 25.

Second, since the energy required to preheat the heating element to the set operating temperature without increasing air increases with increasing mass of the heating element 43, the serpentine heating element is more energy efficient because of a set size impedance at a lower volume of the element. For example, halving the volume of a heating element also decreases its mass twice. Thus, the energy required to heat the heating element 43 to a given operating temperature without moving the air is proportional to the mass of the heating element 43 and its thermal capacity, and reducing the mass twice reduces the energy consumption. Such a heating element 43 is more energy efficient.

A third advantage relates to the thermal rapidity of the reduced volume (mass) serpantine heating element 43 (i.e., the temperature response of the heating element temperature change). The transient response of a heating element is defined as the time required to change the temperature of the heating element from one temperature to another at a higher temperature after it has received a specified amount of energy. Since the reaction time of the heating element 43 is proportional to mass, the reaction time of the reduced mass heating element 43 is reduced. Thus, the serpentine heating element is not only compact, energy efficient, but also has a higher temperature change rate (i.e., it heats up faster to operating temperature). These advantages of the present invention allow for a much more efficient heating element.

Thus, the resistance of the heating element 43 is increased by the use of a serpentine heating element having a plurality of S-shaped regions without increasing the overall length of the heating element without reducing its cross-sectional area. It will be understood that a form other than that shown in FIG. 8, the heating element 43 may be formed by applying the described principles, and, also, a compact and efficient heating element may be realized.

In the heating elements 43, the serpentine portion 131 is cut in one, desired manner, preferably using a laser (CO ₂ laser). Since high precision of the serpentine portion 131 of the heating element 43 is required (for example, the gap B in Fig. 8 is 0.1 to 0.25 mm wide), laser cutting is preferred. Because laser energy is concentrated in a small volume, it provides a versatile, fast and accurate automatic workpiece machining. Laser cutting of the workpiece avoids impact on the material being cut and, moreover, does not expand the material under heat and therefore is less oxidized than other types of cutting, such as electric discharge. Other treatments such as electrical discharge processing, precision stamping, chemical etching and other chemical treatments can also be used. PALT 3859 B can also produce heating elements by conventional punching using a punch and matrix, but such Equipment makes this alternative less attractive, especially when forming a serpentine part. In addition, the serpentine can be cut using a laser, and the torch 25 can be joined together. Yttrium-Aluminum-Pomegranate (YAG) laser is best suited for welding. For example, the heating units 89 and terminals 91 are best connected by CO ₂ or YAG laser welding. Likewise, the heating element 43 is welded to the rear ends 101 or contact areas 129, preferably by laser, to the inlet / outlet terminals 104 located in the base 50 or to the respective control device elements or sockets. It will be appreciated that other various connection methods may be used to assemble the burner 25 components.

The present invention reduces the potential for thermal damage to heating elements 43. As shown in Figs. 6, the rear end portions 101 (or contact areas 129) are welded to the terminals 104 or other electrical circuit elements or components of the control unit, and the portion of the heater in the form of a serpentine that emits heat is formed as an integral part of the heater 43; it is necessary to weld the individual parts of the serpentine and its ends. Undesirable deformation has been observed when heating the heating elements in which the serpantine is welded from separate parts. Preferably, the longitudinal line of the rear members 101 and the contact areas 129 of the heating elements are aligned with the serpentine 131 axial line. It has been observed that misalignment of these axes results in deformation of the heating elements 43 during heating. The opposite ends 131 'and 131' 'of the serpantine 131 join symmetrically with the smooth portion of the heating element 43, i.e. at the joining points, the S-shaped bending directions overlap. This symmetry prevents the opposite ends of the serpentine from rotating in opposite directions during heating and prevents the heating element 43 from being damaged. The ends 131 'and 131' 'of the current supply portions 137' and 137 '' connecting the equal parts of the heating element to the serpentine are cut at an angle as shown in FIG. 6. Angle-cut current supply portions 137 'and 137' 'reduce the thermal effect on the smooth portion of the heating element.

The heating elements 43 and the heating device 39 also have other features that can solve the problems associated with heating and repeated heating. For example, heating element 43 is expected to expand (elongate) during heating. Since the heating elements 43 are fixed at the front end to the outlet assembly 91 attached to the front 121 of the heating device 89 and the end 101 of the heating element 43 to the ring 99, elongation of the heating elements may bend the heating element in the 23 direction or undesirably bend it. , from cigarette 23. Survival from cigarette 23 increases the gap between the heating element and the cigarette 23. The increase in the space decreases the heating intensity and efficiency of the tobacco layer 57 by changing the area of thermal contact between the heating element 43 and the cigarette 23. The outward bending of the heating elements is prevented by folding them inwardly against the cigarette 23 as shown in FIG. 3A. The inward bending of the heating element improves the thermal contact between the heating element 43 and the cigarette 23. The heating elements 43 are bent in one of the known ways, for example by pressing the cylindrical heating unit shown in FIG. 6, in the form of the required concavity. It is preferable for the heating element to be bent by stamping or pressing prior to forming a cylindrical heating unit 89. the inwardly curved heating element further deforms inwardly during heating. It is best that the heating element is slightly bent inward throughout the length of serpentine 131. Angle-cut transition regions 137 'and 137' 'may be bent more than the more precise serpentine portion 131. Thus, the site of thermal deformation is moved from a more vulnerable position of the heating element to a less vulnerable one. If desired, the serpentine portion of the heating element may be enclosed in a ring (not shown). It is understood that this ring conducts heat and, as the serpentine portion 131 of the heating element 43 extends, bends it inward to the cigarette 23.

In addition to the heating unit 89 described above, the heating device 39 further comprises a spacer 49 and a base 50 of the heating device 39, which are shown in FIGS. 3A. The spacer 49 shown in FIG. 10A-10C and is formed by an outer surface 97 which is pressed to the outlet 91 and heating members 43 by a ring 99. The spacer 49 has a base wall 139, a base inner surface 81 that restricts further movement of the cigarette 23 in the burner 25 and locking the cigarette 23 and a cylindrical inner wall 141 into which a cigarette 23 is inserted into the cavity 23. The passage portion 47 '47' communicating with the air-excited sensor 45 is formed in the base wall 139. It is preferred that the passage portion 47 'be through the base wall 133 and drilled or otherwise formed parallel to the axis of the spacer 49. The base wall 139 also includes a portion 55 'of a cavity 55 in which a light sensor 53 is inserted. The aperture 143 facilitates first pull-in and influences the system's pull-on resistance (RTD) during the first pull of a cigarette 23 by providing an additional airflow from the surrounding area to the cigarette. area adjacent to the return filter 63. As the tobacco layer 57 is wound on paper 69 limiting the air flow, the heating element 39 heats a portion of the cigarette, air enters through the aperture 143 and the cigarette 23 through the return filter 69. 69 a sufficient amount of air enters the cavity of the cigarette 23 and the drag resistance (RTD) is reduced to a greater extent than would otherwise be obtained. The return filter 69 must be as stiff as possible and pass the aforementioned air flow during the first stroke so as not to pass back into the burner 25, the aerosol remaining in the cavity 79 after the cigarette 23 is drawn. After the first smoking of the cigarette 23 and the formation of smoke, the tobacco layer 57 and the paper 69, which were ignited by heating the cigarette with heating elements, become more permeable to air. Therefore, after the first pulling of the cigarette 23, the air flow through the first pulling opening 143 and the return filter 63 during the other pulling-ups is immaterial.

A cylindrical base 50, which is shown separately in FIG. 11A-11B, consisting of openings 107 in the main wall 151, inlets 107 or guides 104 used for connection to the outlets 95, provided in the main wall through which heating elements 43 extend over the outer base surface 105 and the inner wall 155 are the diameter of the cylinder and the inner wall is greater than the outer diameter of the gasket 49 and is approximately equal to the outer diameter of the ring 99. The spacer 49 is preferably slid between the inner wall 169 of the base 50 and the air channel nozzle 87 and secured by friction. The spacer 49 and base 50 may be secured by additional means, such as screws, clamps or adhesive means. Also, the spacer 49 and the base 50 may have ridges and grooves (not shown) that provide a certain orientation of the spacer and base. The permeability channel 47 at 47 '' is made in the main wall 151 and extends from the axis 50 of the base 50 to its outer edge. If desired, a portion 47 '' is in the form of a groove formed on the inner surface 157 of the base, and the groove is required to release the air compressed by the spacer 49 at the base. Preferably, the portion 47 '' is a hole drilled longitudinally in the main wall 151 and intersecting in the radial directions. The portion 55 '' of the cavity 55 is formed in the main wall. Parts 47 'and 55' of spacer 49 are aligned with respective parts 47 '' and 55 '' of base 50 and form a passageway 47 and cavity 55.

In the embodiment shown in FIG. 5, a detail 49A of FIG. 12A-12D. The outer surface 97A of the member 49A is in the form of a cylinder to which the ring 99 is attached for the outlet of the heating elements. The portion 49A further comprises a main wall 139A, an inner surface 81A of the main wall blocking further movement of the cigarette to the burner 25 when the cigarette 23 is positioned relative to the heating members 436 and the cylindrical inner wall 141A of the member 49A. Part 49A, also, must have a first fastening hole (not shown). The throughput channel 47A communicating with the air gust excitation sensor is formed in the main wall 139A. Preferably, the permeability passage 47A is a hole extending through the main wall 139 parallel to the axis 49A of the member. The cavity 55A housing the light sensor 53 is formed on the main wall 139A. As noted above, the rear ends 101 of the heating elements 43 and preferably at least two outlets 95 protrude from the outer surface 105A of the member 49A and are connected to the power source 37 and the control unit 41. At least two of the ends of the member 49A are formed. grooves or openings 107A through which grooves or openings 107A through which the rear ends 103 of two outlets 95 extend through the base of part 49A are provided. The rear ends 101 of the heating elements 43 are bent to conform to the shape of the flange end 109, and protruding from the outer surface 105A of the base 49A of the member 49A to the outer edge iii of the end 109 and arranged in radial directions. The air channel nozzle 87 is mounted on the outer edge 111 of the flange end 109 and secures the ends 101 of the heating members 43 in this position.

To better explain first the heating device 39 shown in FIG. 3A-3B, and without repeating the above, a description of the smoking system 21 is provided below. It will be understood that the following description may be used to explain the heating device 39A shown in FIGS. 5, as well as other embodiments not shown or described herein. As mentioned above, the heating device may utilize other devices performing various functions, such as forming a space adjacent to the heating elements of the cigarette.

A ring 99 securing the heating members 43 and terminating 95 on the outer surface 97 of the gasket 49 is shown in FIG. 13. The inner diameter of the ring 99 is such that it envelops and clamps the heating elements to the cylindrical outer surface 97. Friction prevents the heating elements from moving. Longitudinal grooves 159 are formed on the inner surface of the ring 99, having an angle between them of 90 °, which is adapted to fit thicker outlets 95 and press against the outer surface 97. The air channel nozzle 87 is pressed at the first end 161 to the base 50 and second end 163 to the cap. 83. At the first end of the air channel nozzle 161, an outwardly projecting edge is formed which engages a groove 167 in the inner wall 50 of the base 50. Similarly, the air channel nozzle 171 engages the inner groove 173 of the cap 83. FIG. 5, from the nozzle 87 shown in FIG. 3, characterized in that an inner groove 165A is formed at the first end 161A of the nozzle which engages with an outer edge made on the outer edge 111 of the end 490 of the member 49A and flange 109 extending through the coupled member 43A and air duct nozzle 87A. As will be explained below, by examining Figs. 17, if necessary, air flow may be increased by drilling or otherwise forming one or more holes in portions of the heating device 39, such as air duct nozzle 87, preferably along nozzle 87, at points where air flow is not blocked or forced by a curved path 83; gasket 49 before entering the cigarette 23.

The cover 83 of the heating device 39 shown in FIG. 3A, and cap 83A shown in FIG. 5, are completely similar except that the inner wall 177 of the cap 83 is longer than the inner wall 177A of the cap 83A. The inner diameter of the cap 83 is nearly equal to the diameter of the cigarette 23 and is preferably smaller and the cigarette 23 is slightly compressed by inserting it into the burner 25 and not moving in the burner. The longer inner wall 177 provided in the lid 83 is more suitable because the cigarette is mounted better. The cap 83A is shown in more detail in FIG. 14A-14D.

The cap 83A has a plurality of longitudinal apertures or passageways 179A beginning at its anterior, rounded end and extending in the direction of its posterior surface 181A. Through the apertures, air enters the interior of the heating device 39A, into the cavity between the cigarette and the air channel nozzle 87 such that the transverse flow of air passes inwardly through the tobacco layer 57 against panting portions 131. of heating elements 43. 3A, in the best embodiment of the cap 83 of the heating device 39, the apertures or air passages 179A are formed closer to the posterior plane 181 than to the front end 93, thereby obtaining the desired tension resistance (RTD). In another embodiment of the cap, grooves (not shown) are provided along with the longitudinal apertures, which are made on the inner wall of the cap. In interpreting Figs. 14A-14D, the groove 183A is formed at the posterior plane 181A and holds the optional protective nozzle 85, which is shown in more detail in FIGS. 15A-15B.

The heater nozzle 85 is a tubular member with first and second ends 185 and 187, respectively, which may be inserted into grooves 183A. The circular groove 183A has a larger diameter than the apertures or passageways 179A, which facilitates the entry of air into the interior of the heater 39 when the cigarette lighter is pulled.

The cap 83, which is shown in FIG. 3A, can be produced by casting or machining. The cap is molded as a homogeneous member, such as cap 83A shown in FIG. 5. If the cap is made mechanically, it is best to make it as two fittings, the outer member 83 'and the inner member 83' ', which are shown in Figs. 3A. The surface of the inner member 83 '' is provided with a circular groove, which is required for joining the outer member 83 'and the inner member 83' 'to form a groove 183 when both parts are assembled. in a manufactured cover.

The heater nozzle 85 may be removable and replaced with a new stroke set by the smoking device, such as 30-60 cigarettes 23. The nozzle 85 protects the inner wall 169 of the channel nozzle 87. the remaining aerosol formed between the heating elements 43 and the air channel nozzle 87. The remaining aerosol affects the heating device nozzle 85 rather than the air channel 87.

The heating nozzle nozzle 85 is made of heat-resistant paper or plastic and is replaced by a smoking device for the set number of cigarettes 23. Thus, in contrast to the tube, the tube nozzle 85 in the smoking system 21 of the present invention may be used many times in a tube construction of an aerosol barrier tube mounted in a tobacco odor device, which will be described below and is discharged with the device (cigarette). . It also simplifies the production of cigarettes 23 and reduces the emissions of each cigarette when it is broken.

FIG. 16 is a diagrammatic representation of the flow of air through the heating device 39 and the cigarette 23 as the air is drawn through the muffler filter 71. The air through the muffler filter 71 enters air through longitudinal apertures or passages 179 into the interior of the heater 39. nozzles (not labeled in this case) through the cigarette 23, heating members 43 (not shown) and through the air-permeable outer sheath 69 and tobacco layer 57 (or holes therein) into the cavity 79 in the cigarette 23. Air from cavity 79 through the longitudinal transition 77 , a second open pass filter 73 and a muffle filter 71 pass to the smoker. The number and size (diameter) of transitions 179 are selected by optimizing the overall material response (TPM) of the smoker. In the illustrated embodiment, six or eight passageways 179 are formed in cap 83.

As depicted in FIG. 17 may, if necessary, be provided with other or additional passageways 179 to allow air to enter the heating device 39 and the cavity 79 in the cigarette 23. For example, one or more radially directed passageways 189 may be provided in the heating device 39, in each suitable detail , usually in the air duct nozzle. The heating device 39 may be provided with longitudinal passageways 191 formed in the base and spacer (not shown in the drawing). Also, the passage passage 179 in the cap 83 may be a hole as described above, or as longitudinal grooves formed in the inner wall of the cap. As described above, a return filter 63 may be provided, if necessary, to allow longitudinal flow into the cavity 79 when the smoker pulls the cigarette for the first time.

If necessary, the burner 25 may be provided with an optional tapered tube (not shown) which is inserted into the interior of the heater 39 for piercing the return filter 63 of the cigarette 23 during the insertion of the cigarette. This tube is configured to be inserted into a cavity 79 and feeds a direct stream of air into the cavity 79 when the smoker pulls a cigarette 23. The front of the tube has one or more openings that are best formed at the sides of the tube and allow high speed airflow. directed in such directions that a rotating air stream is generated in the cavity. This rotation of the air stream improves the mixing of incoming air with the aerosol and vapor generated in the cigarette 23.

The electrical control unit 41 of the smoking system 21 is shown in FIG. 18. The device comprises a logic circuit 195 implemented as a special application integrated circuit or ASIC, sensed by a gust of air.

The electrical control unit 41 of the smoking system 21 is shown in FIG. 18. The device comprises a logic circuit 195 implemented as a special application integrated circuit, or ASIC, an air-triggered sensor 45 that detects a smoker pulling a cigarette 23. The light sensor detecting the duck 23 of the cigarette 23 in the burner 25, a liquid crystal indicator ( LCD) 51, which shows the amount of zippers remaining in the cigarette lighter 25, the power source 37, and the time interval forming circuit 197. The logic circuit 195 is a conventional logic scheme that implements the logic functions described below. A programmable logic array (for example, ACTEL AlOlOA FPGA PL 44C manufactured by Actel Corporation, Sunnyvale, California) can be programmed to perform digital logic functions and analog functions performed by other components. Thus, ASIC implements both analog and digital functions in one component. The control and logic circuits used in the present invention are similar to those known, for example, in U.S. Pat. 5060671, and are included in this description.

In the best embodiment of the present invention, the eight heating elements 43 (not shown in Fig. 18) are connected to the terminal 37 of the positive power source and through the corresponding field transistor (FET) switches 201-208 to the common ground terminal. Each heating element switch 201-208 is actuated by controlling them to logic circuit 195 through respective outputs 211-218. Logic circuit 195 generates a signal to enable or disable one of the switches 201-208, thereby activating or deactivating the respective heating element.

An air-triggered sensor (sensor) 45 emits a signal indicating that the smoker has pulled a cigarette 3838 B in response to unnecessary short-term air pressure drops that can unnecessarily turn on the heating. elements, from the prolonged reduction in pressure that occurs when the cigarette is pulled. A piezo-resistive pressure sensor or an optical sensor with a damper, which sends a signal to an operational amplifier which outputs a logic signal to a logic circuit 195, can be used as an air-triggered sensor. of firm Honeywell Ine. MicroSwitch, Freeport, III., Either a NOVA NPR1-5-0.25G sensor manufactured by Lucas Nova, Freemont, California, or an SLP004D sensor manufactured by SenSym Incorporated, Sunnyvale, California.

A light sensor 53 detecting the presence of a cigarette in the burner provides a signal to logic circuit 195 when the cigarette 23 is properly inserted into the burner 25 (i.e., the cigarette is remote from the light sensor mounted in the spacer 49 and base 50 of the heater 39 and detecting the light reflected from the cigarette. .A smoking system may employ a light sensor OPR5005 Light Sensor manufactured by OPTEK Technology Ine., 1215 West Crosby Road, Carrolton Texas 75006.

In order to consume less energy, it is preferable that the air-gushed sensor 45 and the light sensor 53 are periodically turned on and off using a shorter period of operation (i.e., the sensors operate between 2% and 10% of the period). For example, it is preferable for the gust-triggered sensor 45 to be on for 1 millisecond when the entire period is 10 milliseconds. If, for example, during four consecutive periods, i.e. after 40 milliseconds, a gust-evoked sensor 45 detects a pressure drop or air movement indicating the cigarette 23 is pulled out, which is the output 221 of the sensor 45, which is fed to the logic circuit 195. The logic circuit 195 transmits through one of the outputs 211-218. a signal switching the respective switch with the field transistor 201-208 to the ON state.

Similarly, the light sensor 53 operates for 1 millisecond when the entire period is 10 milliseconds. If the light sensor detects four successive light pulses reflected from the cigarette 23 in the burner 25, a signal is generated at its output 223 which is fed to the logic circuit 195. The logic circuit 195 transmits through an output 225 a signal-activating air-gauge sensor 45. The logic circuit 195, also, transmits the enable signal to the indicator 51 via output 227.

The modulation method described above reduces the average current required to power the air-triggered sensor 45 and the light sensor 53, thereby extending the life of the power source 37.

The time interval forming circuit 197 forms time intervals such that equal amounts of energy are consumed at each interval. The output 229 of the time-out circuitry circuitry generates a trip signal which is fed to the logic circuit 195 after one heating element has been turned on by switching one of the eight switches with the field transistor 201-208 to the on state and a current flowing through the heating element 43. time frame. In accordance with the present invention, a time interval forming circuit 197 supplies a trip signal to the logic circuit 195 after a time interval which is determined as a function of the voltage of the power source which decreases with heating of the heating elements. The interLT 3859 B waveguide circuit 197 also prevents the heating element 43 from being energized when the power source is discharged. Other configurations of time interval formation may be used, such as those described below.

During operation of the device, the cigarette 23 is inserted into the burner 25 and its presence is detected by the light sensor 53. The light sensor 53 transmits a signal to the logic circuit 195 through the output 223. The logic circuit 195 determines the state of the power source 37 is not too small). If, after inserting the cigarette 23 into the burner 25, the logic circuit detects that the voltage of the power source 37 is too low, the indicator 51 will start flashing and the operation of the device will be blocked until the power source 37 is charged or replaced. Power Supply 37 Voltage is controlled during heating of the heating elements 43 and is turned off if the voltage drops more than the set voltage.

If the power source 37 is charged and the voltage is of a suitable magnitude, the logic circuit 195 transmits a signal through output 225 to an air-triggered trigger sensor 45 to verify that the smoker has not started smoking. At the same time, the logic circuit 195 transmits a signal from output 227 to an indicator 51 setting the liquid crystal indicator so that it reflects the number 8 times the smoker can pull the cigar 23.

When the logic circuit receives a signal from the air-triggered sensor 45 output 221 that there is a continuous pressure change or air movement, it switches off the light sensor 53 for a cigarette-pulling period, thereby saving energy. The output 231 of the logic circuit 195 is fed to a time interval forming circuit 197, activating a time interval corresponding to a constant thermal energy input. The logic circuit 195 reduces by one the contents of the counter which determines which heating element 43 will be turned on and sends a signal through the respective output 211218, switching the respective switch with the time transistor 201-208 to a state ~. This switch will remain in the status until the time-out circuit operates.

Upon completion of the time interval formation, the output 229 of the time interval formation circuit 197 generates a signal which is transmitted to the logic circuit 195 and the field transistor switch 211-218 which is in the on state is switched to the state off by interrupting power to the heating element. Logic circuit 195 also reduces the content of the counter and supplies a signal through output 227 to indicator 51, which will now indicate that one cigarette is less per stroke (i.e., seven strokes remaining after the first stroke). When the smoker pulls the cigarette 23, the logic circuit 195 will switch the next set field transistor switch 211218 to the ON state and power will be supplied to the next set heating element. This process will be repeated until indicator 51 reflects 0, indicating that there are no more zips in the cigarette. After removing the cigarette 23 from the burner 25, the light sensor 53 will generate a signal that the cigarette is not present and the logic circuit 195 will be reset to the initial paw.

Alternatively, the other circuits described below can be integrated into the logic circuit 41 or used as auxiliary circuits. For example, protective circuits can be used to protect the unit from damage. In one, a safety chain that protects against two cigarette 23 pull-outs during an earlier LT 3859 B when power source 37 has not yet been able to recover. The other protective circuit protects the heating elements 43 when an inappropriate object is inserted into the heating device 39. For example, a cigarette 23 may have markings that are identifiable upon insertion of the cigarette into the burner 25 and cannot be activated without recognition.

Another smoking system 222 implemented in accordance with the present invention is illustrated in FIG. 19. The smoking system 222 comprises a cigarette 224 and a burner 226 into which a cigarette is inserted through a port 228. The smoking system 222 is implemented as a system for supplying air through a central portion in which, during smoking, the air moves through a central (inner) portion of the cigarette 224. The torch 226 comprises a power source (not shown), which is mounted at the opposite end of the opening 228, and a control device (not shown).

The torch 226 is housed in a housing 232 which gives the device the appearance of a regular cigarette. The housing 232 is preferably in the form of a tube and may be made of heat-resistant plastic or aluminum or formed of spirally wound heavy paper. Through the holes 223 in the housing 232 into the burner 226 Air is drawn in during smoking. If necessary, air passages (not shown) can be made in the cigarette 224 or other locations of the burner 226 to form the desired air flow.

Cigarette 224 is similar to cigarette 23. Cigarette 224 consists of a tobacco layer 257 formed on a holder 259 which holds tobacco flavoring 261, preferably composed of tobacco. The tobacco layer 257 is reinforced with a return filter 263 at one end and a cylindrical open transition filter 265 at the opposite end. The first open transition filter 265 may have a longitudinal transition (not shown). The CigareLT 3859 B Continuous 224 also includes a cylindrical bump filter 276, which is a type of RTD (Resistace to draw) filter. Cigarette 224 may include a second open-pass filter (not shown) that improves air mixing of the vapor phase tobacco reaction product as described above. The return filter 263, the first open transition filter 265, and the tubular tobacco layer 257 determine the cavity size of the cigarette 224. The first open transition filter 265, the return filter 263, and the bump filter 271 are best fitted using techniques that can be implemented in high-throughput production equipment. .

Unlike cigarette 23, cigarette 224 is provided with an annular aerosol impermeable tube 273 disposed about and spaced at a predetermined distance from the tobacco layer 257. The aerosol impermeable tube minimizes condensation of aerosol produced by heating tobacco flavoring on the inner walls of housing 232. The aerosol blocking tube 273 is preferably secured with the cigarette 224 to the ring 275 of the open transition filter 263. The ring 275 and the aerosol impermeable tube 273 are sufficiently rigid to protect the cigarette 224 from breakage and are repaired so that the tobacco layer 257 and the aerosol impermeable tube 273 uniform spacing. The sheath or reinforced paper 269 connects a muffle filter 263 adjacent to an open transition filter 265, a ring 275, and an end of an aerosol impermeable tube 273.

The burner 226 comprises a heating device 239 consisting of a row, preferably eight, of the cigarette 224 heating elements 243. The heating elements 243 are in the form of a strip extending from a point adjacent the opening 228 of the burner 226 to a point in the return filter 263. The first ends of the heating elements 243 are connected, preferably those ends which are at the return filter cavity 245 and the second ends at the opening 228 are compressed so that the cigarette 224 can be inserted without affecting the heating elements 243. The heating elements 243 enters into the gap between the tobacco layer 257 and the aerosol impermeable tube 273.

A schematic view of the heating device is shown in Figs. 20. The heating device 239 comprises a base 249, a holder 251, and a plurality of heating element-bearing supports 253 made of heat-resistant and non-conductive material. The heating elements 243 are mounted on supports 253. The heating elements are connected at opposite ends 243 'and 243' 'by electrically conductive contacts 255A and 255B.

The ends of the heating elements 243- are joined together to form a common outlet for the heating device. General outlet 291 is connected to a connecting plate 293 which is connected to a conductive contact 255A electrically connected to the ends of the heating elements 243 '. Plate 293 has one or more air channels 29 that allow air to enter a portion of the cigarette adjacent to the return filter 263 during cigarette tightening.

The heating device ring 97 surrounds the neck 299 mounted about a portion of the common outlet 291 adjacent the connecting plate 293. The neck 299 has a single passageway 301 in which air enters the passageways 295.

Conductive terminals 303 are extended through ring 297 and form connections to conductive terminals 255B. The contacts 255B extend along the heating element supports 253 and engage with the heating element 243 ends 243 ''. .

The terminals 255B 'of the conductive contacts 255B' are preferably curved. This facilitates clamping of the ring 297 and the neck 295 whose ends 255B 'contact the terminals 303. This connection method facilitates the repair and replacement of the heating elements 243 and the burner 226. Outputs 303 and general outputs 291 are plugged into respective sockets (not shown) and electrical control circuit 241 is connected to heating elements 243.

The device for producing cigarettes 224 is shown in Figs. 22, a portion 224 'consisting of a tobacco layer 257, a first open transition filter 265, and a return filter 263, is shown in FIG. 21. The holder material 259 'is pulled away from the drum 323 by the feed shafts (not shown). In the carrier material (mesh) 259 'used in this embodiment, zones with tobacco flavoring are formed. These zones may be formed at point 323 or at another location, for example, prior to rotation of the drum 323. The support material 259 'is pulled past the point 327 where adhesive areas 261A are formed on the surface of the material 259. In an alternative embodiment, the tobacco layer may be applied to the entire surface of the carrier material and the adhesive areas 261A may be applied to the tobacco fragrance at the desired locations.

The filter feeding station 329 is located below the adhesive coating station 327.

The filter feeding station 329 comprises a rotating drum 331 which feeds filters of one type 333 or another 335 onto adhesive areas 261A formed on the surface 259 of the carrier material. The rotation speed of the device 331 is matched to the feed rate of the carrier material 259.

At wrapping point 337, located below the filter feeding station 329, the carrier material 259 'is wound around the filters 333 and 335 to form a long rod, which periodically includes filter zones and zones with odorous tobacco. The resulting rod is cut at 339. Cutting station 339 is provided with means for cutting the rod through the middle of filters 333 and 335 such that the cut filter 333 and the cut filter 335 are the respective open pass filters 265 and return filters 263 of the two cigarette blanks. the return filters 263 are processed to form a tapered end facilitating the heating members 243 to envelope the cigarette portion 224 '. Once cut, each workpiece 224 'is inserted into an aerosol impermeable tube 273 and secured by a ring 275. The diameter of the tube 273 is larger than the length of the long bar and the length is equal to the length of the cigarette 224. The cylindrical muffler filter 271 is attached to each of the open transition filters 265, and each aerosol impermeable tube 273 and muffler filter 271 are wound to the material used for rolling the cigarette at other points (not shown).

Another embodiment of the smoking system 421 is schematically illustrated in FIG. 23. System 421 implements a smoking system in which air is drawn through the periphery during cigarette pulling and the heating elements 443 of the burner 425 are disposed in a cavity 427 associated with the annular portion 423 of the cigarette.

The cigarette 423 consists of a tobacco layer 457 coated on the opposite side of the cavity 427, a flavored tobacco material 461, a holder 459, an aerosol impermeable tube 473, a stopper 475, a ring open transition filter 465, a ring return filter 463 and a muffle filter 463. .

The cavity in which the fragrant tobacco material 461 reacts when heated by the heating elements 44J3 is defined by an open transition filter 465, a return filter 463, a tobacco layer 457 and an aerosol impermeable tube 473. The cigarette 423 is wrapped in a reinforced paper 469. The heating device includes a stopper 477. which is mounted on a sequential stopper 475 and reduces aerosol transmission through the heating device areas of the smoking system 421. The stopper 477 is provided with apertures through which conductors 491 are pierced to supply signals controlling the heating elements 443.

A schematic view of an alternative electrical control unit 541 is shown in FIG. 24. The control unit performs several functions. It controls the heating elements 43, usually eight, by isolating a suitable heating element 43 at each point in time when the air-triggered sensor 45 is actuated. It supplies a pulse of a defined duration to the heating element 43 for a duration such as to produce a tobacco fragrant reaction. . It controls indicator 51, which shows: 1) how many cigarette pulls are left; 2) that the voltage of the power source 37 is different from the target voltage range; 3) that the cigarette is not inserted in the burner 25; and 4) that the heating device is not mounted in the burner, for example, the heating device 238 is not mounted in the burner 226.

The control unit 541 also controls the amount of energy supplied by the power source 37 to each heating element 43. Since the voltage supplied from the power source 37 can change after each cigarette pull, the same energy is supplied to the heating elements 43 during each cigarette pull. quantity by varying the duration of power supply. The control circuit 541 controls the voltage of the power source 37 upon activation of the heating element 43 and supplies the energy until the required amount of thermal energy is released in the heating element 43.

As shown in Figs. 24, the control unit 541 comprises a logic circuit 570, a decoder transcoding the binary code to a decimal (BCD) 580, a voltage detector 590, a time interval generating circuit 591, an air-excited sensor 45, an indicator 51 and a charge transmission circuit 593. a logic circuit that implements the logic functions described herein, such as a programmable logic array, ACTEL A1010A FPGA P244C manufactured by Actel Corporation, Sunnyvale, California) that is programmed to perform these functions. Ideally, the logic circuit operates at a low tactical frequency (for example, 33 Khz), thereby reducing power consumption.

Each heating element 43A-43H is connected to the positive terminal 37 of the power source and to the common (ground) terminal via the respective field transistor 595A595H. Field transistors 595A-595H are controlled by decoder 580 (preferably CD4514B decoder, which decodes 4-column binary input code to 16 outputs 581-588). Decoder 580 receives two types of signals from logic circuit 570: 1) binary element 43A which must be On; and (2) an On or Off signal to activate this heater.

The decoder 580 is coupled via a terminal 580B to a charge transmission circuit 593 which supplies a voltage that is used to control the field transistors 595A-595H. The charge transmission circuit 593 consists of a diode 594 which is connected to a power source 37 and a capacitor 595 which is a logic circuit 570. The logic circuit 570 consists of a conventional switching circuit (unpaired 3859B) connected to a terminal 5762 that enables the charge circuit 593. at terminal 593B to obtain a voltage, preferably twice that of power source 37. Diode 594 prevents current from returning to power source 37. Thus, this twice the voltage at decoder input 580B is used to control the blockages of field transistors 595A-595H. Higher voltage control signals increase system performance 541. The resistors 596A-596H are connected in series to the barrier of the field-effect transistor 595A-595H and, together with the barrier-to-source capacitance of the field-effect transistor, increase the input time constant and filter out noise from the control unit 541.

The gust-triggered sensor 45 supplies a signal to logic circuit 570 as the smoker pulls the cigarette (i.e., a constant pressure drop of about one inch of water column). A piezo-resistive pressure sensor controlling an operational amplifier output from a logic circuit 570 can be used as an air-gust sensing sensor 45. For example, a pressure sensor NPH-5-062.5G Nova manufactured by Lucus Nova of Freemont, California or SLP004D sensor manufactured by Shen Sym Incorporated, Sunnyvale, California.

For energy saving purposes, it is best to have the air-triggered sensor periodically switched on for a short period of time (for example, the sensor operating time can be between 2 and 10% of the total period duration). For example, it is best that the gust-induced sensor 45 is activated for 0.5 ms for a period of 16 ms. This modulation technique reduces the average current consumed by the air-excited sensor 45 and extends the life of the power source 37.

The time interval circuit 591 generates an off signal by supplying it to the logic circuit 570 when one of the heating elements 43A-43H has been energized for a period of time during which the heating element has to emit a specified amount of energy. According to the present invention, it is preferable for each heating element to be actuated so long that it emits a constant amount of energy (e.g., 5 to 40 joules, or preferably about 15 to 25 joules), regardless of the loading voltage of the power source 37. Thus, an input of the heating element 43 and the voltage of the power source 37 is provided to the input 591A of the time-varying circuit 591, considering that the resistance of the heating elements is known and constant (i.e., 1.2 ohms). When a fixed, constant amount of energy in the heating element is emitted, the output 591B of the time interval forming circuit 591 generates a signal which is fed to the input of the logic circuit 570 57 8.

The best realization of the time interval forming circuit 591 is shown in Figs. 24. Circuit 591 comprises an input 591A fed from a logic circuit 570 having a voltage magnitude ranging from zero to power source 37 during operation of the heating element, a resistor-capacitance circuit 601 consisting of resistors 603-606, capacitor 607, and a diode 608 and a level detector 602. The input signal is filtered by a resistor-capacitive circuit 601 and used to control the voltage level detector 602. It is best to use a circuit ICL7665A manufactured by Maxim Corporation of Sunnyvale California as a voltage level detector 602. The parameters of the circuit 601 are selected such that the output 591B of the time interval forming circuit 591 changes from high to low after a time interval in which a constant amount of energy has been supplied to the heating element. Of course, other configuration time interval formatting schemes may be used. If necessary, the control unit 541 can limit the maximum time interval at which a constant amount of energy is to be applied to the heating elements. For example, if the power source voltage is so low that it will require a power supply of 20 joules for a time interval greater than 2 seconds, circuit 570 will generate an auto-off signal at output 571, 2 seconds after the heating element is energized.

In an alternate embodiment of the present invention, a time interval forming circuit 591 supplies a trip signal to a logic circuit 570 which is formed after a specified time interval from the moment of heating of the heating elements and is independent of the energy supplied to the heating elements. Thus, the time interval forming circuit 591 generates an off signal after, for example, a fixed time interval, which may be from 0.5 to 5 seconds.

Voltage detector 590 controls the voltage of power source 37 and supplies a signal to logic circuit 570 when this voltage is:

1) lower than the first applied Voltage (for example, below Voltage)

3.2V), and the signal indicates that the power source needs to be recharged;

Greater than the second applied voltage (for example,

5.5V), and the signal indicates that the power source is fully charged after being discharged to a voltage lower than the first set level. An ICL7665A comparator manufactured by Maxim Corporation, Sunnvale, California may be used as a voltage detector.

As described above, the logic circuit 570 controls the decoder 580 in a signal generated at output 571. The logic circuit 570 controls the indicator 51, which represents the number of strokes remaining in the smoker smoking a cigarette and is best used in a system with eight cigarette strokes. segment liquid crystal display (LCD). Thus, for a cigarette with eight fractions of tobacco flavor, the indicator shows a figure of 8, followed by a count of 1 after seven strokes. The last time the smoker pulls the cigarette will be 0.

Also, indicator 51 indicates 0 when no cigarette is present or the heater is not inserted into the burner (for example, the heater elements 243 are not inserted into the heater 239). Also, indicator 51, flashing periodically at 5 Hz, indicates that the voltage is different from the set values, i. y. decreased significantly (for example, less than 3.2 V) or the power source was not fully charged. For example, if the power source drops below 3.2 V after the first cigarette pull, indicator 51 flashes twice per second to indicate 7.

The logic circuit 570 determines which heating elements or heater not to be placed in the burner according to the signals at inputs 597A and 598A, to which the voltage is proportional to the voltage drop across high impedance resistors 597 and 598 (for example, 1 Mom). One of the terminals of resistors 597 and 598 is connected to the junction of 595G and 595H and after removing the heating elements the junction of the field transistors is disconnected from the power source 37. The voltages on the resistors 597 and 598 are equal to earth potential and are controlled by logic circuit 570. Also, not inserted into the burner, two logic 0s are detected at logic circuit 570 inputs 597A and 598A. When the heater is inserted into the electric burner, the power source 37 is connected to resistors 597 and 598 through heating elements 43G and 43H, respectively. A voltage drop occurs on resistors 597 and 598 and the logic circuit detects two logic 1 Inputs 597A and 598A. Logic circuit 570 controls the voltage drops on the two resistors 597 and 598, since using only one resistor can cause a false indication that one heating element 43G or 43H is energized and the voltage drop on the respective resistor becomes close to ground potential. Therefore, when using two resistors and switching on one of the field-effect transistors, for example 595G, the voltage drop on resistor 598 gives a logic 0, and the voltage drop on resistor 597 is 1. Thus, according to the signals recorded on the two resistors 597 and 598 operation OR logic circuit 570 detects whether a heating unit or heating device is inserted into the burner.

The logic circuit 570 has an additional input 599 for signaling whether a cigarette is present in the burner. The signal fed to input 599 is formed by a conventional switch, which can be switched mechanically or electrically. However, if a carbon fiber material (network) was used to make the cigarette as described above, it is best that the input 599 signal be formed by connecting a separate electrode to the carbon fiber network and controlling the leakage currents flowing through that network. Since the carbon fiber material is not very well insulated, it is a heating device having one terminal connected to a power source 37 as shown in FIG. 23, will contact the carbon fiber network and a small current will flow through it, regardless of the state of one of the field transistors 595A-595H. In the present embodiment, the presence of a cigarette is detected by controlling this effluent stream by an electrode connected to a carbon fiber network.

Likewise, by measuring the electrical conductivity of a carbon fiber material, similar to detecting the presence of a cigarette in a burner, cigarettes can be identified (i.e., distinguished by the type of X or Y cigarette inserted in the burner). This feature of the present invention is realized by placing two additional inputs (not shown) in logic circuit 570 which are connected to two electrodes in contact with the carbon fiber material (network). Different types of cigarette material are manufactured with different specific resistances (i.e., the type of carbon fiber and / or binder used to obtain different specific resistances) unambiguously reflecting the type of cigarette, and this resistivity is determined by the type of cigarette inserted in the burner. Information about the type of cigarette in the logic diagram can be used to determine the distribution of the electricity supplied to the heating elements.

For example, a first type of cigarette is made from a carbon fiber material having a first resistivity specific to the first size and a second type of cigarette having a second specific resistance. Thus, the logic circuit 570 can actively control the supply of energy to the heating elements by detecting an impedance characteristic of the type of cigarette inserted in the burner. Based on what has been described above, the power supply conditions may vary depending on the type of cigarette or mark that has been identified on the burner. For example, if logic circuit 570 detected a reflective type of cigarette impedance, it would control the heating device so that the heating elements would be supplied with 15 joules or 20 joules of energy to heat different types of cigarettes. In addition, the logic circuit 570 has a circuitry that prevents power supply if the impedance characterizing the cigarette is incompatible with a given type of torch.

Returning to FIG. 23, before the smoker pulls the cigarette for the first time, indicator 51 indicates 8, i.e., eight cigarette pulls are possible. The logic circuit 570 feeds the address of the first heater element (e.g., 43A) to the inputs 571 and the decoder 580 determines the heater element (for example, through output 581) that will be activated. When the cigarette is pulled by the cigarette, the air-triggered sensor 45 sends a high-level signal through clamp 575 to logic 570 indicating that the pressure inside the burner has decreased, for example, by one inch of water column. At the output 571 of the logic circuit 570, a signal appears which activates the outputs of the decoder 580 and activates the field-effect transistor isolated by the decoder connected to the first heating element. The first switch with the field transistor 595A switches the heating element 43A to the on state.

At the same time, with the activation of the first heater 43A, the time interval generating circuit 591 begins to control the instantaneous value of the energy supplied to the first heater 43A and provides a logic signal to the logic input 578 of the circuit 570 when this value reaches its target value (e.g., 20 joules). ). Output 571 of logic circuit 570 generates an off signal, which is fed to a decoder 580, toggling a switch with a field transistor to an off state that turns off the heating elements.

Similarly, until the next cigarette pull, the logic circuit 570 sends the address of another heating element, such as 43B, to the decoder 580 from output 571 and the field transistor 595B by the next cigarette pull will turn 3859B on. Also, logic circuit 570 supplies a signal to indicator 51, which is adjusted to reflect a number 7 indicating that the smoker has seven cigarette butts.

If necessary, the logic circuit 570 may include a circuitry for determining the time interval between two cigarette pulls, thereby allowing the energy source to charge. For example, the logic circuit 570 may include a circuit (not shown) that prevents the signal being applied to output 571 and to decoder 580 for 6 seconds after the last signal sent to decoder 580 is off. This mode of operation for the smoker may be indicated by a 51-inch indicator seeding, for example, at a frequency of 4 Hz (i.e., at a different frequency or other indicator display duration than that used to indicate power source voltage changes). After the set time has elapsed and the cigarette is pulled by the smoker, control unit 541 functions as described above.

Although the control system shown in FIG. 23, the logic circuit 570, the decoder 580, the voltage detector 590, and the time interval forming circuit are shown as discrete modules, but it is possible to implement them in a single integrated circuit (i.e., one crystal of an integrated circuit).

If necessary, a cigarette realized in accordance with the present invention may include means for indicating to the smoker that the cigarette is reusable. For example, in one embodiment, an unused cigarette has a strip that is peeled off or otherwise removed from the cigarette before being inserted into the burner. Panau35 on a given cigarette This bar or similar tag is not present. Also, unused cigarettes may have other physically replaceable areas that are torn, pierced, crushed, or otherwise affected during insertion into the burner. Thus, the smoker can visually observe physically damaged areas to determine which cigarette has been used.

Furthermore, the replacement cigarette may, if necessary, have indicator areas indicating that the cigarette has already been heated. For example, a cigarette may have a heat-sensitive indicator area that changes color to indicate to the smoker that it has been heated. Also, the heat sensitive area may have a melting strip or other similar material indicating to the smoker that the cigarette has been heated. In addition, other means, electrically or mechanically activated, may be used to indicate to the smoker that the cigarette has been used.

It is to be understood that the described best embodiments and illustrative examples of the present invention may be modified or improved without departing from the spirit of the invention as set forth below.
