Description

[Technical Field]

[0001] The present invention relates to a substance inhalation device, for example a smoking device. [Background technology]

[0002] Today, substance inhalation devices, such as smoking devices, especially electronic cigarettes, are becoming increasingly successful as smokers become more aware of the health damage caused by smoking. Electronic cigarettes, sometimes called vapes, are electromechanical or electronic devices that generate an aerosol intended to be inhaled. This aerosol, or "vapor," or "artificial smoke," resembles the smoke produced by the combustion of tobacco. This vapor (aerosol) may or may not be flavored (tobacco, fruit aroma, etc.) and may or may not contain nicotine.

[0003] US Pat. Nos. 5,629,299, 5,729,310, 5,729,4 ...20, 5,729,430 and 5,729,440 disclose substance inhalation devices.

[0004] Currently, the primary commercial technology for e-cigarettes is atomization or aerosolization, which involves converting a substance into particles small enough to be transported through the air, i.e., in an aerosol. In the case of e-liquids, atomization or aerosolization involves dispersing the e-liquid into fine droplets. More specifically, the primary commercial technology for e-cigarettes is based on the use of a heating resistor to atomize or aerosolize the e-liquid. Specifically, the principle of such e-cigarettes involves generating an aerosol that mimics tobacco smoke. This technology involves heating the e-liquid (called vaped e-liquid) with a heating resistor; the user must trigger the resistor's heating, which heats, vaporizes, and almost instantly condenses into fine droplets to generate an aerosol that the user can inhale. Activation of the resistor's heating can be either manual (e.g., by a switch) or automatic (e.g., by an electromechanical device that detects the user's inhalation and activates the resistor accordingly).

[0005] A substance inhalation device based on the heating of a liquid, such as an e-cigarette, generally consists of the following main elements: a battery (which powers the atomizer), an atomizer (which houses a resistor that vaporizes the liquid), a tank (a container for the liquid), and a mouthpiece that allows the vapor (aerosol) coming out of the atomizer to be inhaled.

[0006] Other additional elements may be present, such as, for example, an electronic power module, a voltage variator, a temperature controller, a puff number counter, means for communicating with an electronic device, such as a computer or a smartphone, or any other device, such as a charging device.

[0007] The main element of current e-liquid heating-based inhalation devices, such as current e-cigarettes, is the atomizer, which includes a resistor, a component whose function is to heat the e-liquid to a high temperature of at least 190°C (generally 188-290°C) to generate an aerosol. These atomizers generally contain a resistance wire surrounding a strand, which can be made of, for example, silica fiber or cotton, and / or a wadding. The strand or wadding stores the e-liquid and transports it to the resistor by capillary action, whereby the e-liquid is heated and vaporized. When the atomizer and cartridge are inseparable and form a single component, the latter is called a "cartomizer" or a cartridge with an integrated atomizer. The cartomizer supplies the e-liquid to the atomizer via a wadding. When the supply is secured using a strand system, the term "clearomiser" is used. Currently, atomizers, primarily used for heating, are consumables, and their lifespan varies significantly depending on the model, use, and type of e-liquid.

[0008] Conventionally, the liquid to be heated contains the following components: - propylene glycol (PG) and / or vegetable glycerin (also called glycerol) (VG) based mixtures, optionally with the addition of a combination of ethanol and / or water (<5%); - aromas generally derived from the food industry, and, optionally, - variable rate nicotine, generally 0-3.6% (i.e., 0-36 mg / ml); Contains:

[0009] However, while PG and / or VG-based e-liquids are widely dominant (dominant, common), there are some alternatives, such as polyethylene glycol in the form of propane-1,3-diol or PEG400.

[0010] Unfortunately, with regard to substance inhalation devices, such as smoking devices, and in particular electronic cigarettes, which are based on heating a liquid to generate an aerosol, even though the vapors (aerosols) generated have for some time been considered less harmful and less toxic to the body than smoking cigarettes, recent studies have demonstrated that these vapors are in fact not entirely harmless to the human body. Studies have detected the presence of significant amounts of carcinogenic molecules such as methanal, acrolein or ethanal not only in the vapors (aerosols) generated by electronic cigarettes, but also in the bodies of users of such smoking devices.

[0011] Thus, to date, substance inhalation devices, especially electronic cigarettes based on the heating of liquids containing aromatic substances, are subject to the production of toxic products, especially solvents and volatile organic compounds (VOCs), as well as potentially carcinogenic toxic compounds such as formaldehyde-hemiacetal, acrylonitrile, acrolein, propylene oxide, and acrylamide. Furthermore, propylene glycol and glycerin, which are almost systematically used in liquid form to maintain substance inhalation devices, especially electronic cigarettes, are safe at ambient temperature, but when heated, are believed to produce potentially carcinogenic toxic compounds that are inhaled by the user.

[0012] Generally, substance inhalation devices, such as smoking devices, and in particular electronic cigarettes, which are based on heating liquid to generate an aerosol, involve the presence of a battery, primarily to power the heating element (generally a resistor). Nevertheless, any battery has limited autonomy, especially when its size and weight are reduced so that it can be integrated into the substance inhalation device, for example in a smoking device.

[0013] Other types of substance inhalation devices, such as e-cigarettes, in which no heating is required to obtain an aerosol are known in the art. Generally, this type of substance inhalation device, such as a smoking device, comprises a mister or nebulizer atomizer and a compressed air cartridge. If such substance inhalation devices, such as smoking devices, are operable, they have, among other things, certain drawbacks, the main one being that when the compressed air cartridge is empty, the substance inhalation device is no longer operable unless the compressed air cartridge is replaced.

[0014] All of this means that if the user does not have an energy source to charge the battery and / or a replacement compressed air cartridge, the substance inhalation device, e.g. a smoking device, will be momentarily inoperable, which can prove particularly restrictive for the user.

[0015] Therefore, there is a real need to provide a substance inhalation device, such as a smoking device, that "mimics" conventional tobacco smoke obtained by burning tobacco, is optimized, and optionally and preferably at least partially solves the above-mentioned problems by minimizing and even eliminating the problems associated with the presence of carcinogenic and toxic molecules, especially those generated by heating at high temperatures.

[0016] [Patent Document 1] US Patent Application Publication No. 2003 / 0079443 [Patent Document 2] European Patent No. 1917992 [Patent Document 3] US Patent Application Publication No. 2018 / 0146711 [Patent Document 4] US Patent Application Publication No. 2012 / 0118301 [Patent Document 5] US Patent Application Publication No. 2018 / 0343921 Summary of the Invention

[0017] To address these problems, according to the present invention there is provided a substance inhalation device, for example a smoking device, which device comprises the following components: - an atomizer, - an assembly including the atomizer and a first tank containing at least one substance to be inhaled, the atomizer being in fluid communication with the first tank; - a second tank configured to contain pressurized gas and in fluid communication with said assembly; a mouthpiece in fluid communication with an outlet of the atomizer; a trigger configured to release a quantity of the gas outside the second tank and towards the assembly; a pump configured to draw in ambient air and inject and compress it into said second tank.

[0018] In particular, to address these problems, the present invention provides a substance inhalation device, such as a smoking device, which device comprises the following components: - Cold liquid atomizer, - an assembly including the atomizer and a first tank configured to contain at least one substance to be inhaled in liquid form or in solution, the atomizer being in fluid communication with the first tank; - a second tank configured to contain pressurized gas and in fluid communication with said assembly; a mouthpiece in fluid communication with an outlet of the atomizer; - a trigger configured to release a quantity of said gas outside said second tank and towards said assembly; a pump configured to draw, inject and compress ambient air into said second tank.

[0019] According to the invention, said first reservoir contains at least one substance to be inhaled in liquid form or in solution, in particular when a substance inhalation device according to the invention is used.

[0020] For example, according to the present invention, the aforementioned pressurized gas is air or pressurized oxygen, more specifically air displaced (drawn) in the ambient environment, which is then injected into a tank and compressed.

[0021] By the term "cold liquid atomizer" is understood an atomizer in the sense of the present invention that does not require heating of the liquid in order to obtain a fine dispersion of the liquid, in particular to obtain an aerosol, which may be, for example, a mister or nebulizer, in particular a cold mister or cold nebulizer, in the sense of the present invention.

[0022] As soon as a substance inhalation device, e.g., a smoking device, according to the present invention is equipped with a pump configured to suck in ambient air, inject it into the aforementioned second tank and compress it, the operator can ensure the filling of the second tank at any time and compress the air displaced in the surrounding environment (ambient air) therein. Thus, a substance inhalation device, e.g., a smoking device, according to the present invention, is always operable and does not require replacement of the compressed air cartridge.

[0023] Preferably, according to the invention, the substance inhalation device does not have a battery, which not only makes it possible to reduce the weight of the substance inhalation device according to the invention, but also makes the device more environmentally friendly, since batteries pose serious pollution problems not only during their manufacture but also with regard to their recycling.

[0024] Preferably, according to one embodiment of the present invention, the inlet of the first tank is in fluid communication with the second tank, in particular with the outlet of the second tank. According to this embodiment, the first tank and the second tank can be arranged in series or in parallel.

[0025] Advantageously, according to the invention, the at least one substance to be inhaled in liquid form or in solution contained in the first tank is not pressurized therein. According to the invention, the substance to be inhaled in liquid form or in solution contained in the first tank is driven by the gas released at the start of the second tank. Preferably, according to the invention, the drive of the substance to be inhaled in liquid form or in solution occurs in the tank (compartment), but the substance to be inhaled in liquid form or in solution is not pressurized, so that the substance can be expelled from the tank.

[0026] According to the invention, the substance to be inhaled, preferably in liquid form or in solution, is bubbled in the gas released at the start of the second tank, so that the substance inhalation device according to the invention operates as a bubbler.

[0027] Advantageously, according to one embodiment of the present invention, a first inlet of the cold liquid atomizer is in fluid communication with the second tank, and a second inlet of the cold liquid atomizer is in fluid communication with the first tank. According to this embodiment, pressurized gas from the second tank enters the cold liquid atomizer through the first inlet (gas inlet) of the cold liquid atomizer and passes through the cold liquid atomizer, thereby allowing, for example by the Venturi effect, the substance to be inhaled in liquid form or in solution contained in the first tank to enter the cold liquid atomizer through the second inlet (inlet for the substance to be inhaled) of the cold liquid atomizer, which is in fluid communication with the first tank containing the substance to be inhaled in liquid form or in solution.

[0028] Preferably, according to an embodiment of the present invention, the cold liquid atomizer is located at least partially within the first tank.

[0029] Optionally, according to an embodiment of the invention, the cold liquid atomizer and the first tank are mounted in parallel.

[0030] Advantageously, the substance inhalation device according to the invention comprises a plurality of cold liquid atomizers, in particular a plurality of cold misters or cold nebulizers, each of which atomizes one and the same substance to be inhaled in liquid form or in solution, or each of the aforementioned atomizers atomizes a substance to be inhaled in liquid form or in particular in solution. For example, according to the invention, the substance inhalation device can comprise a first cold liquid atomizer atomizing a substance to be inhaled in liquid form or in solution corresponding to an aroma, and a second cold liquid atomizer atomizing a substance to be inhaled in liquid form or in solution corresponding to nicotine, the aerosol coming from each cold liquid atomizer rising through the mouthpiece.

[0031] Preferably, according to the invention, said second tank comprises a porous material, in particular a microporous material, such as zeolite. The presence of a porous or microporous material makes it possible to optimize the amount of (gaseous) air injected and / or compressed into the second tank.

[0032] Advantageously, according to the present invention, the aforementioned pump is a manual pump. According to this embodiment, the fact that the substance inhalation device is equipped with a manual pump allows for the distribution of an electric energy source, for example a battery, thereby making the substance inhalation device more operable at any time. Indeed, instead of using an electric pump to ensure the filling of the second tank, simple manual actuation of the pump allows for the sucking of ambient air and its injection and compression into the second tank configured to contain pressurized gas.

[0033] In particular, according to the invention, said pump is a piston pump, such as for example a bicycle pump.

[0034] Preferably, according to the present invention, the manual pump is a bidirectional pump, i.e., a pump that draws in and propels air into the second tank not only during the reciprocating motion but also during the return motion of the pump piston. This embodiment is particularly advantageous because the substance inhalation device, e.g., smoking device, must be compact and the number of manual pumping movements required to ensure the second tank quickly fills with enough compressed gas (air) must be reduced, allowing the user to inhale the substance to be inhaled in just a few puffs thanks to the amount of compressed air obtained with just a few pumps (pumping movements), preferably just three pumps (pumping movements). Furthermore, such a bidirectional pump ensures faster and therefore more effective filling of the second tank.

[0035] Preferably, the substance inhalation device according to the invention comprises a bidirectional pump with several pistons, in particular several bidirectional pumps, which makes it possible to increase and optimize the amount of (air) gas aspirated and injected into the second tank during a given movement of the pump.

[0036] Preferably, the substance inhalation device according to the present invention further comprises, when operated manually, an additional piston other than the piston of the pump, the additional piston being actuated by pressurized gas contained in the second tank, the pressurized gas enabling the additional piston to perform a displacement movement associated with the movement of the user's finger extensor muscles during manual pumping using the manual pump. This additional piston therefore facilitates pumping by the user by increasing the force applied by the user during pumping using the finger extensor muscles.

[0037] Advantageously, according to the invention, said manual pump comprises actuation means, for example a handle, in particular in the form of a ring.

[0038] Advantageously, the distance of the actuation means of the manual pump (e.g., on the handle) relative to the body of the substance inhalation device (or the opening of the handle) can be adjusted, thereby ensuring an ergonomic fit for any hand size. For example, the actuation means (e.g., the handle) can be positioned according to at least two positions, i.e., two distinct distances relative to the body of the substance inhalation device.

[0039] Optionally, according to the invention, the substance inhalation device may comprise multiple pumps to ensure faster filling of the second reservoir.

[0040] Advantageously, the substance inhalation device according to the invention further comprises a device configured to convert mechanical energy into electrical energy, in particular a device configured to convert mechanical energy provided by a user into electrical energy for operating the pump when the pump is manual. According to one embodiment, this electrical energy, optionally stored in a battery that will be present in the substance inhalation device, can be used to power a heating element as described below. According to another embodiment, this electrical energy, optionally stored in a battery that will be present in the substance inhalation device, can be used to power an electric pump, in particular an electric pump complementary to the manual pump mentioned above. By way of example, such a device configured to convert mechanical energy into electrical energy can be a generator, such as is present in a flashlight, for example.

[0041] Preferably, the inhalation device according to the present invention further comprises a mechanism for closing the second tank, such as a one-way valve, particularly a pressure valve. According to the present invention, such a mechanism for closing the second tank is configured to prevent gas (air) from exiting the second tank when the pressure of this gas in the second tank is too low. According to the present invention, the mechanism for closing the second tank, such as a mechanical one-way valve (opposing force, mechanical stiffness, etc.), is triggered when the pressure in the second tank is below a predetermined threshold, so that gas can no longer exit the second tank. Within the scope of the present invention, it has been determined that the gas (air) present in the second tank must be sufficiently compressed so that atomization results in a suitable aerosol, particularly a suitable mist or nebulized liquid. If the pressure of the gas in the second tank is too low, atomization will not be optimal. That is, too large droplets of the substance to be inhaled are obtained, which travel to the user's mouth in liquid form rather than in aerosol form (e.g., mist or nebulized liquid). Advantageously, in fact, the gas (air) is atomized into droplets (particles) of a suitable size, i.e., between 0.05 and 100 μm, preferably between 0.1 and 20 μm (D 50The pressure must be compressed sufficiently to result in droplets (particles) of size (=3 μm).

[0042] Optionally, according to the invention, said mechanism for closing said second tank is associated with a pressure sensor which measures the pressure in said second tank and makes it possible to control said closing mechanism.

[0043] According to one embodiment of the present invention, the substance inhalation device according to the invention further comprises a mechanism for closing the inlet or, optionally, the outlet of the cold liquid atomizer. Instead of or complementary to the mechanism for closing the second tank, this mechanism for closing the inlet or, optionally, the outlet of the cold liquid atomizer also makes it possible to ensure that too large droplets of the substance to be inhaled do not travel to the user's mouth in liquid form, but rather in the form of an aerosol, for example in the form of a mist or a spray. This mechanism for closing the inlet or, optionally, the outlet of the cold liquid atomizer prevents the pressure at the inlet and / or outlet of the cold liquid atomizer from being too low, thus leading to the formation of too large droplets, with a particle size between 0.05 and 100 μm, preferably between 0.1 and 20 μm (D 50 It may be a valve or any other suitable device that closes when an aerosol (e.g., a spray or mist) containing (formed by) droplets (particles) of size 0.1 μm or less (=3 μm) is not produced.

[0044] Advantageously, the substance inhalation device further comprises a pressure relief safety valve connected to the second tank so as to avoid the risk of explosion or damage to the substance inhalation device if the pressure in the second tank becomes too high.

[0045] Optionally, according to one embodiment, the substance inhalation device further comprises a compressed air cartridge connected to the second tank and / or atomizer, the presence of such a compressed air cartridge constituting an additional compressed air (gas) intake acting alone or in parallel with the second tank and / or atomizer.

[0046] Optionally, according to the present invention, the pump may be connected to a compressed air cartridge so that compressed air (gas) can be supplied to the cartridge during operation of the pump.

[0047] Preferably, according to the invention, said cold liquid atomizer is a mister or a nebulizer, in particular a cold mister or a cold nebulizer.

[0048] In the sense of the present invention, the first tank contains at least one substance to be inhaled in liquid form or in solution, and the second tank contains a pressurized gas.

[0049] Advantageously, when the cold liquid atomizer of the substance inhalation device according to the invention is a mister or nebulizer, in particular a cold mister or cold nebulizer, no heating is required to obtain an aerosol, smoke or smoke-simulating phase. According to one embodiment of the present invention, when the cold liquid atomizer is a mister or nebulizer, in particular a cold mister or cold nebulizer, and therefore no heating is required, the cold-generated aerosol (e.g. mist or spray) contains a reduced amount, or may even be completely free, of toxic and potentially carcinogenic compounds generated by heating, as is the case in current substance inhalation devices, in particular in heated resistance atomizers for current electronic cigarettes, which obtain an aerosol based on heating the liquid.

[0050] According to one embodiment of the present invention, when the cold liquid atomizer is a mister or nebulizer, in particular a cold mister or cold nebulizer, for generating an aerosol or smoke or for simulating, for example, smoke that would be obtained in a conventional cigarette (smoke that is mainly generated by burning tobacco), the aerosol is generated not by heating but at low temperature by the mister or nebulizer, in particular the cold mister or cold nebulizer that constitutes the cold liquid atomizer, resulting in an aerosol in the form of, for example, a mist or spray liquid.

[0051] In the scope of the present invention, the aerosol coming out of the cold liquid atomizer (preferably from a cold mister or cold nebulizer) has a particle size appropriate for reproducing the characteristics of smoke that would be obtained, for example, by combustion, and is between 0.05 and 100 μm, preferably between 0.1 and 20 μm (D 50 It is preferred to have droplets (particles) with a diameter of 3 μm (=3 μm), the size of which is substantially the same from one inhalation to another, and it is emphasized that the mixture (pressurized gas + substance to be inhaled) is homogeneous.

[0052] It is also emphasized that the amount of substance to be inhaled contained in the aerosol emerging from the cold liquid atomizer (preferably from a cold mister or cold nebulizer) is substantially the same from one inhalation to another.

[0053] According to the present invention, a cold liquid atomizer (e.g., a cold mister or cold nebulizer) produces, by atomization, an aerosol (e.g., into a mist or into a spray) having droplets with a droplet size between 0.05 and 100 μm, preferably between 0.1 and 20 μm, preferably between 0.25 and 10 μm, preferably between 0.5 and 5 μm.

[0054] Preferably, according to the invention, said aerosol has droplets with a droplet size distribution with D50 equal to 3 μm, preferably 2.5 μm.

[0055] By definition, an "aerosol" is a collection of fine solid or liquid particles of a substance or mixture of substances in suspension / dispersion in a gaseous environment (suspension / dispersion in a gas).

[0056] By definition, an "atomizer" is a device that serves to finely disperse (reduce to fine particles) a liquid, solution or suspension. In the sense of the present invention, an atomizer has the function of transferring a substance from a first state to a second state that is neither liquid nor solid. In particular, in the sense of the present invention, an atomizer makes it possible to obtain an aerosol as defined above.

[0057] Preferably, the substance inhalation device according to the invention comprises a cold atomizer, in particular a cold mister or a cold nebulizer.

[0058] By definition, a mister is a device that allows for the low-temperature division of pressurized e-liquid into very fine droplets, resulting in a mist. Atomization can be achieved, for example, by atomizing (reducing) the e-liquid using an ultrasonic system or a nozzle that delivers the e-liquid.

[0059] By definition, a nebulizer is a device that allows the liquid to be transformed into a cloud of very fine particles (mist) and is also cold. Nebulization can be performed, for example, by using ultrasound, by feeding liquid and gas simultaneously (coaxial or venturi nebulizers), or by forcing the liquid under pressure through an atomizing head (for example, hydraulic nebulizers).

[0060] Advantageously, according to the invention, the gas, liquid or gas / liquid mixture moving to the inlet of said cold liquid atomizer, for example the inlet of a cold mister or cold nebulizer, has a speed (velocity) of between 0.0025 and 50 m / s, preferably between 0.005 and 25 m / s, preferably between 0.01 and 5 m / s.

[0061] Preferably, according to the invention, the gas traveling to the inlet of said cold liquid atomizer, for example the inlet of a cold mister or cold nebulizer, has a flow rate (mass flow rate) between 5 and 50 Nml / s.

[0062] Preferably, according to the present invention, the liquid traveling to the inlet of the aforementioned cold liquid atomizer, such as the inlet of a cold mister or cold nebulizer, has a flow rate (flow velocity) between 0.001 and 1 ml / s, preferably between 0.1 and 0.5 ml / s.

[0063] The substance inhalation device according to the invention comprises a second tank containing pressurized gas, preferably air or oxygen, or a mixture of air and pressurized oxygen.

[0064] According to the invention, the aforementioned second tank containing pressurized gas may be a tank in the form of a removable and / or rechargeable gas cartridge.

[0065] According to the present invention, preferably the trigger comprises a valve.

[0066] Advantageously, according to the invention, the valve of the aforementioned trigger is arranged between the second tank and the first tank, or between the first tank and the cold liquid atomizer (e.g., cold mister or cold nebulizer), or between the cold liquid atomizer (e.g., cold mister or cold nebulizer) and the mouthpiece.

[0067] A trigger is preferably mounted between the second tank configured to contain pressurized gas and the cold liquid atomizer.

[0068] Preferably, according to the present invention, the substance inhalation device further comprises a device or chamber for mixing the substance to be inhaled in liquid form or solution with the pressurized gas. Preferably, the device or the mixing chamber is located upstream of the cold liquid atomizer (e.g., upstream of the cold mister or upstream of the cold nebulizer) and is in fluid communication with the inlet of the cold liquid atomizer. Such a device or mixing chamber ensures that a homogeneous aerosol containing the expected amount of the substance to be inhaled is formed, and that the droplets (particles) present in the aerosol have an appropriate particle size.

[0069] Advantageously, the invention provides that the aforementioned mouthpiece is exchangeable, and indeed it is provided that different mouthpieces can be connected to the substance inhalation device according to the invention.

[0070] Preferably, according to the invention, the aforementioned mouthpiece is rotatable and makes it possible to close a reservoir containing the substance to be inhaled in liquid form or in solution, so that the substance cannot flow outside the substance inhalation device, for example by performing a rotational movement the mouthpiece closes a reservoir containing the substance to be inhaled in liquid form or in solution.

[0071] According to one embodiment of the present invention, if the substance inhalation device according to the invention comprises a manual pump for aspirating, injecting and compressing ambient air in a second tank configured to contain pressurized gas, a rotational movement of said mouthpiece can make it possible to release an actuation means, e.g. a handle, a piston of the manual pump.

[0072] Advantageously, according to the present invention, the substance inhalation device further comprises a compartment containing a fragrance or aromatic substance or nicotine. Preferably, this compartment is in fluid communication with the aforementioned cold liquid atomizer (e.g., in fluid communication with a cold mister or cold nebulizer). Preferably, this compartment is located downstream of the cold liquid atomizer, and the formed aerosol is filled with the fragrance or aromatic substance by passing through the compartment. For example, the compartment can contain an absorbent material that can be saturated with the fragrance or aromatic substance, or can have a wall coated with the fragrance or aromatic substance (coating). This compartment can be a removable and / or refillable element of the substance inhalation device according to the present invention. This compartment can be configured as an outside air intake (external air inlet), and the fragrance or aromatic substance can be introduced by being present or absent on a support. According to one embodiment of the present invention, this compartment is located in the mouthpiece.

[0073] Preferably, according to the invention, said first tank and said second tank are coaxial.

The presence of such a heating element can heat / condition the mixture (pressurized gas + substance to be inhaled) and / or the aerosol exiting the cold liquid atomizer (e.g., exiting a cold mister or cold nebulizer) so that the user can inhale the aerosol, the temperature of which may be close to the temperature of a puff obtained with a conventional cigarette (tobacco combustion). Advantageously, such a heating element can be present at the outlet of the aforementioned second tank containing the pressurized gas to compensate for the cooling caused by the expansion of the gas as it leaves the second tank. Preferably, according to the present invention, such a heating element does not excessively heat the substance to be inhaled, to avoid or even prevent the generation of toxic and / or carcinogenic molecules due to heating at high temperatures.

According to one embodiment of the present invention, the substance to be inhaled in liquid form can simply be water, optionally distilled water.

[0086] Preferably, the substance to be inhaled in liquid form or in solution has only an aqueous phase or a non-oily, non-viscous or non-semi-viscous solvent, and no oil or viscous or semi-viscous phase.

[0087] According to one embodiment, the device for inhaling substances according to the invention further comprises at least one additional element selected from the group consisting of a valve, a battery, a suction detector or pressure sensor, an electronic power module, a voltage variator, a temperature controller, a puff counter, means for communicating with an electronic device such as a computer or a smartphone, a switch for controlling the aforementioned trigger, a mixer, for example a Venturi mixer.

[0088] According to the invention, the substance inhalation device may also comprise an electronic module for programming the amount of substance to be inhaled in each puff and / or the amount of gas released in each puff and / or the temperature of the heating element.

[0089] Preferably, according to the invention, the trigger is a mechanical trigger, such as a check valve, or an electromechanical trigger, such as a solenoid valve. According to the invention, the trigger, for example a trigger in the form of a (solenoid) valve, can be located either between the first tank containing at least one substance to be inhaled in liquid form or in solution and the second tank containing pressurized gas, or between the second tank containing pressurized gas and the cold liquid atomizer (e.g., cold mister or cold nebulizer), or between the cold liquid atomizer and the mouthpiece.

[0090] The trigger can be a mechanical check valve. When a user applies suction to the mouthpiece, the check valve, which constitutes the trigger and is equipped with a return spring, moves from its rest position and abuts against an abutment in the actuated position (where the check valve is no longer held in the abutment). The return spring is configured to exert a force sufficient to hold the check valve in its rest position when the substance inhalation device is not in use. Suction applied by the user to the mouthpiece shifts the check valve toward the user, creating a depression in the substance inhalation device, which has the effect of allowing a certain amount of gas contained in the second tank to move to the first tank, which contains the substance to be inhaled in liquid form or solution, and transport (push) it toward the cold liquid atomizer (e.g., cold mister or cold nebulizer). The passage of the substance to be inhaled through the cold liquid atomizer results in the formation of an aerosol containing the substance to be inhaled in the form of fine droplets, simulating, for example, the smoke that would be obtained with a conventional cigarette (primarily smoke produced by burning tobacco).

[0091] Preferably, the substance inhalation device according to the invention comprises a turbine for increasing the air flow during inhalation performed by the user.

[0092] According to one embodiment of the present invention, the substance inhalation device comprises a battery capable of powering the compressor and / or pump to compress the gas in said second tank.

[0093] Advantageously, according to an embodiment of the present invention, the substance inhalation device comprises a stop valve located upstream of said cold liquid atomizer, said stop valve comprising a second inlet and a second outlet, the second inlet being connected by a first fluid connection to an outlet of said second tank adapted to contain pressurized gas, and the second outlet being connected by a second fluid connection to the first inlet of said cold liquid atomizer, said stop valve being adapted to stop the substance inhalation device when a pressure P1 of said pressurized gas at said second inlet is less than a reference minimum pressure P minand configured to be closed as long as said pressure P1 of said pressurized gas at said second inlet is less than pressure P min It is configured to open if and as long as it is equal to or greater than this.

[0094] Preferably, according to the invention, said pressure P min is between 0.1 and 1 bar, more particularly between 0.2 and 0.7 bar, and more preferably still between 0.3 and 0.4 bar.

[0095] The presence of such a stop valve ensures that when the cold liquid atomizer receives gas coming from the second tank, the pressure of the gas at the inlet of said cold liquid atomizer is always [P min -PC] (PC is the packing loss between the second outlet and the first inlet). This is especially important for particles (drops / droplets) small enough to simulate smoke, for example particles with a diameter of less than 100 μm, preferably particles with a diameter between 0.05 and 100 μm, preferably particles with a diameter between 0.1 and 20 μm (D 50 This allows the formation of an aerosol (particularly a mist or spray) with a particle size (particle diameter = 3 μm). The stop valve therefore ensures that the cold liquid atomizer always operates with sufficient inlet pressure. In fact, if the inlet pressure of the cold liquid atomizer is too low, the cold liquid atomizer can no longer ensure the formation of an aerosol that simulates smoke, resulting in particles that are too large (for example, particles with a diameter greater than 100 μm) and "sputtering."

[0096] Preferably, according to one embodiment of the present invention, the substance inhalation device further comprises a safety valve having an inlet fluidly connected to a second tank configured to contain pressurized gas and an outlet in fluid communication with the external ambient environment, said safety valve being configured to operate at a pressure P in is the predetermined safe pressure P securite and configured to remain closed as long as the pressure at its inlet is less than inis the predetermined safe pressure P securite It is configured to be as open as possible.

[0097] Preferably, the inlet of the safety valve is fluidly connected directly to the wall or to the outlet of said second tank configured to contain pressurized gas.

[0098] Preferably, according to the invention, said predetermined safe pressure P securite is between 5 and 20 bar, more preferably between 10 and 12 bar.

[0099] Preferably, according to the invention, said predetermined safe pressure P securite is less than 20 bar.

[0100] The presence of such a safety valve makes it possible to reduce the risk of explosion of all or part of the device according to the invention.

[0101] Advantageously, according to one embodiment of the present invention, the device for inhaling substances further comprises a pressure regulator located between said second tank adapted to contain pressurized gas and said cold liquid atomizer. A pressure regulator as known from the prior art regulates the pressure at its outlet to a reference maximum pressure P max It is a device that limits

[0102] The presence of such a pressure regulator makes it possible to obtain puffs of longer duration than would be possible without such a regulator, and this is done for the same pumping energy exerted by the user to compress the gas (air) in the second tank.

[0103] Preferably, according to the invention, said predetermined reference maximum pressure P max is 0.3 to 2 bar, preferably 0.5 to 1 bar, more preferably 0.6 to 0.7 bar.

[0104] In either case, the reference minimum pressure P min is the reference maximum pressure P max is less than.

[0105] Advantageously, according to one embodiment of the present invention, when the substance inhalation device comprises a stop valve, said pressure regulator is located upstream of said stop valve, and according to this preferred embodiment, said pressure regulator has, for example, a third inlet connected by a third fluid connection to the outlet of said second tank adapted to contain pressurized gas, and a third outlet connected by a fourth fluid connection to the second inlet of said stop valve.

[0106] According to a particular embodiment of the invention, said stop valve and / or said pressure regulator and / or said safety valve are located in said second tank adapted to contain pressurized gas.

[0107] The invention also relates to an assembly comprising a substance inhalation device according to the invention and a docking station for said second gas tank (in particular air) and / or charging with electrical energy of the substance inhalation device.

[0108] The present invention also relates to the use of a substance inhalation device according to the invention for atomizing (eg misting or nebulizing) at least one substance to be inhaled.

[0109] These and other aspects of the present invention will be elucidated in the detailed description of specific embodiments of the invention, with reference to the drawings. [Brief explanation of the drawings]

[0112] 1 shows an embodiment of a substance inhalation device according to the invention. According to this embodiment, the substance inhalation device 1 comprises: - a cold liquid atomizer, such as a cold mister or cold nebulizer; - an assembly E comprising said cold liquid atomizer and a first tank containing at least one substance to be inhaled in liquid form or in solution, said atomizer being in fluid communication with said first tank; a second tank 4 containing pressurized gas and in fluid communication with said assembly E; a mouthpiece 5, the inlet of which is in fluid communication with the outlet of said atomizer and the outlet of which is free; a trigger 6 configured to release a quantity of said gas outside said second tank 4 towards said assembly E; a pump P configured to suck in ambient air, inject it into said second tank 4 and compress it; It is equipped with:

[0113] According to this embodiment, the first tank includes a fluid inlet fluidly communicating with the outlet of the second tank 4, which contains pressurized gas. Furthermore, the substance inhalation device 1 includes a trigger 6. According to a first example, the trigger 6 can be a valve that can be opened by a push button or any other equivalent means accessible to the user. According to a second example, the trigger 6 can be a solenoid valve and can include a suction detector or pressure sensor (not shown), a control unit (not shown) connected to the pressure sensor, and a power source (e.g., a battery) (not shown). According to this second example, when the user applies suction to the mouthpiece 5, the control unit measures the depression of the device 1 via the pressure sensor and thus allows the passage of current toward the solenoid valve (constituting the trigger 6), which then transitions from a rest position in which the solenoid valve is closed to an actuated position in which the solenoid valve is open. The second tank 4 contains pressurized gas and is in fluid communication with the aforementioned first tank, which is itself in fluid communication with the inlet of the cold liquid atomizer, which is itself in fluid communication with the mouthpiece 5. The opening of the solenoid valve forming the recess of the device 1 causes the release of gas upon opening of the second tank 4, thereby driving the substance to be inhaled, contained in liquid form or solution in the first tank, toward the inlet of the cold liquid atomizer. Driving the substance to be inhaled in liquid form or solution by the gas not only facilitates the passage of the substance through the atomizer, but also facilitates the exit of the aerosol obtained by the mouthpiece 5, thereby making the use of this embodiment according to the present invention more comfortable for the user. The passage of the substance to be inhaled in liquid form or solution through the atomizer results in atomization, resulting in the formation of an aerosol (e.g., in the form of a mist or spray). The aerosol contains the substance to be inhaled in the form of fine droplets, simulating, for example, the smoke that would be obtained with a conventional cigarette (primarily smoke produced by burning tobacco).

[0114] FIG. 2A shows an embodiment of an assembly E according to the invention, comprising a cold liquid atomizer 2 and a first tank 3 containing at least one substance to be inhaled in liquid form or in solution, said atomizer 2 being in fluid communication with said first tank 3.

[0115] 2B and 2C show another embodiment of an assembly E according to the present invention, which includes a cold liquid atomizer 2 and a first tank 3 containing at least one substance to be inhaled in liquid form or in solution. According to this embodiment shown in FIG. 2C, the cold liquid atomizer 2 is partially located within the first tank 3. More specifically, according to this embodiment, the first inlet e1 (gas inlet) of the cold liquid atomizer 2 is fluidly connected to the outlet of the second tank 4, and the second inlet e2 (inlet for the substance to be inhaled in liquid form or in solution) of the cold liquid atomizer 2 is fluidly connected to the first tank 3 containing the substance to be inhaled in liquid form or in solution. For example, according to this embodiment, the substance to be inhaled in liquid form or in solution moves to the cold liquid atomizer 2 by the Venturi effect, which is due to the pressurized gas passing through the cold liquid atomizer 2. This means that the substance to be inhaled in liquid form or in solution is "sucked" into the cold liquid atomizer 2 through inlet e2.

[0116] Figure 3 shows another embodiment of a substance inhalation device 1 according to the invention, which comprises the same components as those shown in Figure 1, and a stop valve 11 located upstream of an assembly E comprising a cold liquid atomizer and a first tank containing at least one substance to be inhaled in liquid form or in solution, said atomizer being in fluid communication with said first tank, said stop valve 11 comprising a second inlet and a second outlet, said second inlet being connected by a first fluid connection to the outlet of said second tank 4 adapted to contain pressurized gas, said second outlet being connected by a second fluid connection to the first inlet of said cold liquid atomizer, said stop valve 11 being arranged to stop the device when the pressure P1 of said pressurized gas at said second inlet is equal to or exceeds a reference minimum pressure Pmin and the pressure P1 of the pressurized gas at the second inlet is less than the pressure P min It is configured to be open when and as long as it is equal to or greater than that.

[0118] Figure 5 shows another embodiment of a substance inhalation device 1 according to the invention, which comprises the same components as those shown in Figure 1, but also a pressure regulator 10 and a stop valve 11, said pressure regulator 10 and said stop valve 11 being located upstream of an assembly E comprising a first tank containing at least one substance to be inhaled in liquid form or in solution and a cold liquid atomizer, said atomizer being in fluid communication with said first tank.

The stop valve 11 has a gas inlet E gaz and gas outlet S gaz The gas inlet E has a chamber C having an orifice O and a piston PIST connected to a needle p designed to engage with the orifice O. gaz When there is no pressure in the gas inlet E, the needle p is held against the orifice O and thus closes this orifice O by the force exerted by the stretched pretension spring R on the piston PIST. This closed position is reached by the gas inlet E gaz The gas pressure is the reference minimum pressure P min Gas inlet E gaz The gas pressure at the reference pressure P minWhen it becomes larger, the piston PIST moves to the left by compressing the spring R so that the needle p no longer blocks the orifice O, and the stop valve 11 is therefore open, allowing the gas to pass through its inlet E gaz From the exit S gaz Let it pass.

The chamber C contains a stretched pretension spring R to which the needle p is connected. A gas inlet E gaz When there is no pressure in the gas inlet E, the needle p is held against the orifice O and thus closes this orifice O by the force exerted by the stretched pretension spring R. This closed position is gaz The pressure is the predetermined safe pressure P securite Gas inlet E gaz The pressure at the specified safe pressure P securite As soon as the pressure becomes greater than the limit, the stop valve enters the open position and thus the safety valve S sec is open, and the gas flows through its inlet E gaz from the atmosphere (E atm ) exhaust outlet E atm Proceed to.

The pressure regulator 10 has a gas inlet E gaz The gas inlet E has a chamber C having an orifice O and a piston PIST connected to a needle p designed to engage with the orifice O. gaz When there is no pressure in the needle p, it is held at a certain distance from the orifice O and therefore keeps this orifice O open due to the force exerted on the piston PIST by the stretched pretension spring R. This open position is reached by the gas inlet E gaz The gas pressure at the reference maximum pressure P maxThis is maintained as long as: Gas inlet E gaz The gas pressure at the reference maximum pressure P max When the pressure is greater than the pressure, the piston PIST moves to the right by compressing the spring R so that the needle p blocks the orifice O, and thus the stop valve 11 is closed, allowing the gas to pass through its inlet E. gaz From the exit S gaz No longer allowed to pass.

The trigger 6 is connected to the gas inlet E gaz and gas outlet S gaz and a chamber C having a seat S and a piston PIST connected to a needle p designed to engage with the seat S. The needle p is extended outward from the chamber and terminated by a button B. When the button B is not acted upon, the needle p is held against the seat S and thus the passage to the gas is closed due to the force exerted on the piston PIST by the extended pretension spring R. To proceed to the open position, the inlet E gaz From Exit S gaz To allow the passage of gas to the seat S, pressure must be applied to the button B by the user to compress the spring R and shift the needle p so that it no longer abuts the seat S.
