Smoking cigarettes or other smokable products is a very widespread form of enjoyment in human civilisation, so that the enlightened smoker can achieve a more positive assessment of health,
the use of stimulants. Unfortunately, research has shown that previously known solutions to this problem can only be bought at the price of an increased risk of cancer and heart attack, for example by using a cigarette-like smoking object with a combustible cover.

The object of the invention is to provide a device which enables the enjoyment of pyrolysis or of evaporable or otherwise smoke-like drug substances. ■ Without, however, the typical toxic by-products of combustion, such as those in cigarette smoke, reaching relatively high values, and also cannot be adjusted independently of inhalation.

Depending on the design, additional

Experiments have shown that the release of the alkaloids or active substances, e.g. nicotine, which are important for the enjoyment of smoking in larger or smaller quantities, is achieved at much lower temperatures than the approx. 800-1000 degrees Celsius found at the tip of a glowing cigarette. Putting the smoking object down for a longer period of time is also usually problematic, as it involves large losses of smoke: you smoke quickly, but

The poisoning potential of a smokable luxury item can be roughly divided into three components: a construction that remains "ready to smoke" with a filling for up to an hour and longer.

The invention provides for a homogeneously tcmpc- Further defining notes: If the carrier gas in this patent application is referred to linguistically as "carrier gas", this can already be mixed with aerosol. The carrier gas is primarily air, and the use of pressurized (inert) gases such as nitrogen or flavored carrier gases and components in this linguistically defined form does not necessarily always require the exclusive use of be preheated in the apparatus. The carrier gas is usually clearly defined. The chamber is kept closed in the resting state by valves/fjT the listed features can sometimes also be present together without leaving the scope of the invention. The heating takes place at relatively low temperatures, preferably between 50 and 250 degrees Celsius, especially between 60 and 150 degrees, but normally used in this patent application as a collective term for analogues with a high fluorine content. Teflon is a world-famous registered brand name of the DuPont company and is now part of normal speech.

The device can be operated mechanically, electromagnetically or pneumatically. When using a carrier gas under pressure, these methods are even preferable; the escaping gas can then be inhaled without sucking on the device.

If electrical heating is used, it is particularly easy to implement in terms of circuitry and is particularly suitable for mains-powered devices used in enclosed spaces or for portable devices with battery operation. Instead of resistance heating, heating can also be done inductively or using other alternating fields without contact.

An improved version uses an electronically controlled valve mechanism. To do this, a differential pressure sensor or pressure differential switch at the lung-side outlet of the chamber registers the smoker's negative pressure suction, whereupon the valves are released.

A second heat sensor 28 can be installed at a thin - walled point in the exhaust gas duct or can register rapid changes in the exhaust gas temperature directly in the exhaust gas flow, including catalytic burners, which are state of the art and can therefore trigger a new ignition function if required or block the gas supply in the event of a fault. 4.9 Calculation methods and measurements on the model are sufficiently well known from thermodynamics and technology (see e.g. OS DE 3936265 of the Application Af des Gaz, Paris, registered 31.10.89). Pauhr is therefore only used for the described application of a catalytic burner.

A rcnliator module is used which triggers a monoflop or discharges an RC element at each _switchover , which then connects the servo to the rectangular oscillator via a temperature-resistant plastic, such as Teflon or polyimide, which can also be implemented in the form of self-adhesive tapes glued together. The signal already provided can be processed directly at the control input of AS2 in this way. A flat shape as in FIG _1/2 is nevertheless preferable.

becomes.

Signal forming elements and intermediate amplifier components are not shown, since their application depends on the quality of the other components; it is recommended to use the Schmitt-Trigger characteristic. For example, two separate valves of the type shown in FIG 6 can be placed in front of and behind the usual sound chamber to moderate the carrier gas flow.

Slider 13 consists of elastic polyimide self-adhesive tapes which can be moved between different angle positions.

Drawer 2. FIG. 7 shows another possibility of using a rotatable film 4 for valve elements 13 to move contact-free via a diaphragm or from pierced spherical or magnetic ellipsoid bodies with a ferromagnetic field acting through the valve body. This results in a "ser-core" which can be rotated via a force field acting through the valve body. It is possible to use holes laid out next to one another to release or block the carrier gas flow at the same time by using glued films with a metal sheet core. The valve part 13 on the lung side can then be integrated into the stopper as the films themselves have the property of returning to their original position. (The carrier is firmly connected to the device. The inlet valve can remain integrated into the device, as it does not get dirty so easily. Separate movement devices for several valves are also particularly recommended. 3© this material has springy properties.

which generates sufficient restoring force

A slide valve can also be used. You can also omit the "servo" magnet in a cylindrical shape, which is attached to the smoke chamber in a suitable sleeve as a ferromagnetic core in 13 and valve bodies with cross holes that match the openings in the smoke chamber and then receive the carrier gas flow. The slide valve can be solid apart from the cross holes and thus only needs a certain pre-tension of 13 on the valve outer body against this, for particularly good sealing in the resting state . The polyimide film does not have to mediate; however, it can also be glued in at least some areas, it can also be hollow, i.e. tubular, hollow, or otherwise attached.
to guide the radial carrier gas flow

FIG 8 shows a particularly simple design that does not require controlled valves, so that outside the valve body only connecting channels of the transverse holes and carrier gas connections are required. In this case, the smoke agent 3 is connected to the hollow slide. A central tubular body 22 contains the smoke agent 3. Indirect rotation by an external force field is also possible here, whereby an optional tubular body 25 is provided with a preheating device 5, whereby the slide is then designed in the usual way so that it simultaneously acts as an anchor.

The disadvantage is that under such conditions there is of course a somewhat more complicated application, but also dismantling for changing the smoke agent in the valve. The Teflon hose pieces 2» are important because at low pyrolysis temperatures the active substances have much lower vapor pressures than in the vicinity of the embers and therefore larger amounts of carrier gas are inhaled than when smoking cigarettes, and the smoking object "breaks down" into three parts (mouthpiece 20 with outlet valve, end piece 21 with inlet valve and smoke chamber 22).

This enables the object to be smoked in the oven, whereby the air flowing in is well preheated in the narrow gap. The correct choice of material, however, should be emphasized.

In addition to foamed inorganic material, a DEWAR vessel can also be used, preferably made of stainless steel. Such a device can be heated relatively well with batteries.

According to the invention, self-adhesive polyimide tape is used for the force-fitting bonding of highly heated parts (pipe 1, thermal sensor 8, heater 9, valve body 14, etc.) in order to avoid problematic anchoring in thin-walled pipe parts.

In principle, conventional means of smoke cooling or filtering can also be used, but their use is usually unnecessary.
