Description

Technical field

This invention relates to a flameless electronic cigarette with atomization containing no harmful tar, but only a tobacco alkaloid (nicotine).

State of the art

Currently, although it is well known that “smoking is harmful to our health”, there are still one billion people who smoke in the world, and the number of people who smoke is increasing every year. On March 1, 2003, the World Health Organization (WHO) adopted the world's first international non-smoking convention, i.e. “Framework Convention on Tobacco Control”. According to statistics provided by WHO, 4.9 million people per year die from smoking. Although smoking can cause serious respiratory illness and cancer, it is extremely difficult for smokers to completely quit smoking.

The active ingredient in a cigarette is the alkaloid (i.e. nicotine) of tobacco, which is rapidly absorbed after it enters the pulmonary alveolus with a large number of tar droplets produced during smoking. Once absorbed into the blood, the tobacco alkaloid has an effect on the receptors of the central nervous system, causing a “feeling of intoxication” similar to the sensation that analeptics cause, such as the sensation of dizziness or lightness experienced by the smoker.

Tobacco alkaloid is a low molecular weight alkaloid, which is mainly not harmful to the human body, if only it is consumed in small quantities, and whose half-life in the blood is extremely short. Resin is the main harmful substance in tobacco. Tobacco resin consists of several hundred components, and a number of them cause cancer. In addition, it has been proven that exhaled smoke is even more harmful to non-smokers.

In the consumer market there are many inventions of products designed to replace cigarettes that contain tobacco alkaloid but do not contain tar, a relatively pure tobacco alkaloid, and which include a "quit smoking patch", "rinse containing tobacco alkaloid", "aerosol can high pressure, chewing gum containing tobacco alkaloid, etc. These products are free from harmful tar, however, the tobacco alkaloid contained in them is so poorly absorbed that it cannot effectively achieve a high concentration in the blood. As a result, these products cannot create the sense of satisfaction caused by the tobacco alkaloid, and, moreover, cannot replace the smoking habit, which includes “suction” and “puff”. Therefore, such products cannot actually be used as smoking cessation products or as substitutes for cigarettes.

The content of the invention

The present invention, the purpose of which is to create a flameless electronic cigarette with atomization, is able to overcome the above disadvantages by simulating smoking a cigarette, creating the effect of smoking and being closer to a real cigarette.

This invention is characterized in that the air flow sensor located in the mouthpiece of the cigarette constituting the rear end of the cigarette is connected to a high-frequency atomizer oscillator located on the circuit board to activate the connection between the liquid supply channel and the tobacco alkaloid storage solution; that the high-frequency oscillator is then connected to a counting circuit and a display; that the front end of the cigarette consists of an end cap with a battery and a light emitting diode inside. The main working mechanism of an electronic cigarette with atomization according to this invention is that when the cigarette holder is suctioned by mouth, the air flow sensor sends an electrical signal to activate the control circuit; that the high-frequency oscillatory circuit located on the circuit board is activated in order to create an excitation voltage on the atomizer; that another group of differentiated signals generated by direct current is sent to a red light emitting diode to illuminate the differentiated red light. A bimorphous piezoelectric element of the atomizer propagates ultrasonic waves for atomization, in which a solution of tobacco alkaloid stored in a plastic container flows into the atomizer through the liquid supply channel and is micro-sprayed, while spraying onto liquid droplets having diameters of 1-15 μm, of which 75 % have diameters smaller than 6 microns. After mixing with the air stream entering through the air inlet, these drops will enter the bronchi and alveoli of the lungs in an amount of 3-50 μl of liquid at a time. Thus, it is possible that the concentration of tobacco alkaloid in the blood reaches a level of about 30 mg / ml in 10 minutes. The level of consumption of the tobacco alkaloid solution and the time when the smoker smokes every day are presented on the liquid crystal display screen so that a message can be seen to the user with a reminder regarding the need to add the tobacco alkaloid solution using a one-way valve.

This device can mimic the traditional way of smoking and create a smoking effect with a striking resemblance, stimulate the sensation of smoking in a smoker and at the same time not produce any side effect. As a result, the idealistic idea that “smoking is not a danger to our health” can be realized.

The working mechanism of the invention

The invention includes micro-spraying and spraying a water-alcohol solution of tobacco alkaloid in such a way as to make it possible to absorb the solution into the lungs and absorb it into them. The device is a single structure consisting of a shell structure, a high-frequency generator, a liquid tobacco alkaloid and its capsule, a micro-spray gun, an air flow sensor and accessories. The outline of the shell of the structure can be represented in the form of a straight or slightly curved tube, a traditional cigarette mouthpiece, a rod or in the form of other elegant external forms. A cap made of red plastic with a red light emitting diode inside is attached to one end of the shell. The battery used may be a rechargeable lithium battery or a nickel hydrogen battery. A high-frequency oscillator can be a capacitive connecting three-point type oscillator, or an induction connecting three-point type oscillator, or a transformer-type oscillatory circuit, which consists of integrated circuits and tubes of a power amplifier with a frequency in the range of 35 kHz - 2.2 MHz and contains an automatic frequency tuning circuit, resonating piezoids in the form of contours. A liquid crystal display shows the time the device was actuated and the amount of liquid stored. A plastic container is made of silicone rubber or other polymeric materials that are impervious to tobacco alkaloid. The one-way filling valve is sealed with a ball or cone pressed by a spring. The air flow sensor is made of garlands of membrane thermistors or silicon chips. The device includes a spray diaphragm with a group of holes for micro-spraying in the center and a radially polarized piezoid in the form of a ring attached to it. On the outer periphery of the group of holes for micro-spraying mounted ring with corrugation around the circumference. A single-layer or multi-layer longitudinally polarized annular piezoid is attached to the vibration diaphragm corresponding to the spray diaphragm. The vibrating diaphragm is provided with grooves or a spacer, which are used to form the fluid chamber together with the spray diaphragm. A small hole is created in the peripheral part of the fluid chamber for connection to a fluid supply passage having a damping effect. The device uses signals to change the electric current to actuate, respectively, two piezoids in order to generate longitudinal pressure waves and radial waves to squeeze the liquid out of the micro-spray hole and spray it. Each piezoid has two ends for inputting piezoelectric signals. The frequency of the piezoelectric signals may be different or may be identical. Two piezoids can be one of the following devices: PZT, PMN, PNN, PSN, PMN-PT, PNN-PT, PSN-PT, PZN-PT, created in the form of a single-layer structure or a multilayer structure with various components. The vibration diaphragm and the spray diaphragm are made of single crystal silicon chips or made of corrosion-resistant metals or alloys such as nickel plate, nickel-cobalt alloy plate, nickel-palladium alloy plate, nickel-chromium-palladium-rhodium alloy plate etc. The vibrating diaphragm and the spray diaphragm are connected to each other, forming a fluid chamber, into which a mass of fiber is used, used to supply the liquid, which is made from natural fiber or synthetic fiber. The tobacco alkaloid (nicotine) solution consists of tobacco alkaloid, water, ethanol, glycerin, menthol, tobacco essence, antioxidant and ammonia solution. Tobacco alkaloid is a mixture of four tobacco alkaloids extracted from the main tobacco extract. It is also called the main tobacco alkaloid, in which nicotine is the largest part. Therefore, it is possible to replace tobacco alkaloid with pure nicotine. The concentration level of alkaloid (nicotine) tobacco is from 0.1% to 30%. The device can also be used to administer pharmaceuticals or precursors of pharmaceuticals to the lungs through the oral cavity or nasal cavity, therefore, it can serve as a portable device for spraying with the introduction of drugs.

Figure 1, number 1 shows a red glass Perspex; number 2 - loading sleeve; number 3 - diode emitting red light; number 4 - spring; number 5 - lithium battery; number 6 - shell with threaded connections 18; number 7 - circuit board; number 8 - liquid crystal display; number 9 - wire for signal transmission; number 10 - a container made of plastic; number 11 is a one-way valve for filling liquid, connected to the opening of the plastic container; number 12 is a sealed separator plate; number 13 - channel for supplying fluid; number 14 - spray; number 15 - air inlet; number 16 - air flow sensor; number 17 - cigarette holder and number 19 - current switch.

According to Figure 1, a single structure is assembled from various components. A block diagram of the design of the electrical circuit on the circuit board 7 is shown in FIG. 2. The high-frequency oscillator includes an automatic frequency tuning circuit in order to maintain the piezoids in a resonating state. The atomizer 14, consisting of a bimorph piezoelectric element, performs two functions, i.e. micro-spraying and spraying. The atomizer design is shown in FIG. 3. The mechanism of operation of the atomizer consists in the fact that two piezoids are used to actuate the vibrating diaphragm and the spray diaphragm, respectively, forming a chamber for supplying liquid. An annular piezoid and a vibrating diaphragm are connected to form a piezoelectric transducer generating high-speed longitudinal pressure waves in the spray direction in order to make it possible to spray liquid through the micro-spray hole at high speed. A piezoid in the shape of a ring and a spray diaphragm with holes for micro-spraying are connected to form another piezoelectric transducer, directing radial vibrational waves to liquid droplets flowing from the micro-spraying holes, for further separation of the droplets. By laying the loose mass of fibers in the fluid supply chamber formed by the vibrating diaphragm and the spray diaphragm, there is a more uniform distribution of energy and liquid for each micro-spray hole in the group of micro-spray holes. Vibration diaphragm and spray diaphragm can be made of manocrystalline silicon chips, corrosion-resistant metals or alloys. The distribution curves of liquid droplets having different diameters can be obtained by changing the excitation voltage and the frequency of the piezoid in the form of a ring and an annular piezoid. It is envisaged that the diameter of the micro-spray hole is 4-10 microns, the diameter of the liquid droplets is 1-15 microns, the device can also be used simply after adjusting and filling with nicotine solution.

Preparation of a solution of tobacco alkaloid.

Water, ethanol, glycerin, menthol, tobacco essence and an antioxidant are added sequentially to a liquid tobacco alkaloid extracted from tobacco having a concentration of over 95%, and then an ammonia solution is added to bring the pH to a range of 7.5-11. The level of concentration of tobacco alkaloid varies in the range of 1-30%. If the concentration level is too high, errors may increase. 20% to 80% water should be added and 20% to 80% ethanol should also be added. Highest glycerol concentrations should be less than 45%. The antioxidant used is bottled hydroxytoluene.
