Description

[Technical field]

[0001] The present invention relates to the field of electronic cigarettes, and in particular to oral-nasal electronic cigarettes. [Background technology]

[0002] Electronic cigarettes, also known as electronic atomizers, are mainly classified into two types: vapor electronic cigarettes (Vapor) and heat-not-burn electronic cigarettes (HNB electronic cigarettes). Compared with traditional heat-cured cigarettes, both types of electronic cigarettes can deliver nicotine and significantly reduce the amount of harmful substances, such as tar, carbon monoxide, and nitric oxide, that enter the human body, and are therefore used by hundreds of millions of users around the world as "harm reduction" products.

[0003] At present, the harms of e-cigarettes have not yet been studied in depth and thoroughly, and new harms are also ignored under the guise of "harm reduction". For example, the essence in cigarette tar is inhaled into the lungs from a person's mouth along with the atomized aerosol and smoke, and the essence in HNB solid tobacco cartridges and tobacco paste, as well as the explosive bead essence in the filter, are also inhaled into the lungs from a person's mouth along with the atomized aerosol and smoke. Due to physiological differences between human organs, edible essences that are safe and harmless to the stomach are not necessarily harmless to the lungs as well. For example, vitamin E acetate is a food additive that has been used by people for a long time, but when inhaled into the lungs along with the aerosol of e-cigarettes, it is not only not digested and metabolized, but also covers the alveoli, causing lung inflammation or even human death. Butanedione and 2,3-pentanedione have long been permitted to be added to foods as food essences, but when inhaled into the lungs, they can be deposited in the airways and cause blockages, exacerbating airway inflammation and resulting in "popcorn lung."

[0004] In addition, fats and oils, fructose, sucrose, acesulfame potassium sweetener, aspartame sweetener, vitamins, long-chain esters, ethylene glycol, borax, coumarin, glycine, anthranil cinnamate, safrole, thiourea, acetoin, etc. are all common ingredients in food essences, but if inhaled into the lungs along with the atomized aerosol or smoke, they pose severe harm to the user's health.

[0005] Nicotine / nicotine salt, propylene glycol, glycerin, and essence are the four main components of liquid tobacco tar, and sweeteners, cooling agents, and aroma substances are usually classified as essences. The solid tobacco cartridges and tobacco paste in HNB e-cigarettes also need to add essences such as sweeteners, cooling agents, and aroma substances. E-cigarettes containing essences are called flavored e-cigarettes or flavored e-cigarettes. Currently, essence has become an essential key substance for vapor e-cigarettes and HNB e-cigarettes, and e-cigarettes lacking essences lose their competitiveness, resulting in users returning to smoking traditional heat-cured cigarettes that produce large amounts of tar. However, the category of essences is very complicated, and currently more than one thousand kinds of essences are used in the e-cigarette industry. These essences include natural, synthetic, or animal or plant extracts. Further additives to the electronic cigarette along with the essence include essence solvents, by-products during essence production, and unspecified impurities mixed in when the essence is filled.

[0006] In order to increase the selling point in the market, more essences are used in e-cigarettes, and the types of essence solvents and essence-related substances are also increasing. The heating temperature of the atomized liquid of vapor e-cigarettes is 180-280℃, and the heating temperature of HNB e-cigarette cartridges and tobacco paste is 250-380℃. The essences, essence solvents and essence-related substances in these tobacco raw materials are at risk of decomposing into harmful substances such as formaldehyde, acrolein and acetone at high temperatures.

[0007] In addition, the current usage methods of electronic cigarettes by users can be divided into two smoking methods: "oral microcirculation" and "pulmonary macrocirculation". Specifically, when the essence molecules are inhaled from a person's mouth together with atomized aerosol or smoke, they pass through the "oral mucosa" which is a microcirculation, or the "oral mucosa-throat-trachea-bronchi-lung-bronchi-trachea-throat-oral mucosa" which is a macrocirculation, and are then exhaled from the nasal cavity or the person's mouth, where they are sensed by the olfactory nerve in the nasal cavity. In this case, the essence molecules are not only lost in quantity, but are also diluted by other substances in the surrounding aerosol or smoke, causing interference with their aroma, which causes complaints from users about the reproducibility of the taste of electronic cigarettes. Therefore, manufacturers must increase the amount of essence added to liquid tobacco tar and solid tobacco cartridges and tobacco pastes.

[0008] Currently, essences, essence solvents, and essence-related substances, which are found in liquid tobacco tar, solid tobacco cartridges, and tobacco paste, are all inhaled into the lungs through the mouth of a person. Pathological, toxicological, and scientific studies on their hazards cannot be conducted in a timely manner, and as a result, safety measures are often delayed. For example, vitamin E acetate and diacetyl were banned from use in e-cigarettes after they were found to be harmful to the lungs after causing death in 2019. However, the e-cigarette industry still uses many essences that have not been determined to be safe for the lungs by scientific studies, increasing the risk of use for many users.

[0009] Propylene glycol and glycerin are common organic solvents in liquid tobacco tar, and the mass ratio of both in liquid tobacco tar is about 90%. However, the propylene glycol in e-cigarettes is usually obtained from chemical industries such as coal and oil, not from plants. Scientific studies have confirmed that propylene glycol is severely damaging to the oral cavity of e-cigarette users. Although glycerin is said to be derived from plants, there is still a lack of scientific and systematic pathological and toxicological research on whether it is safe after entering the lungs from the mouth and being deposited in the alveoli for a long period of time.

[0010] A Chinese patent application with application number CN201310228824.X discloses a single-passage nasal e-cigarette that uses the nose instead of the mouth to absorb smoke. This abandons the mouth as the inhalation route of the e-cigarette, and inhales the "mixed smoke" produced by "heating the tobacco raw material" entirely through the nose. The fact that the "smoke" inhaled is "mixed" means that it contains not only essence, but also other atomized substances that are likely to interfere with the nasal olfactory nerve's sensing, such as nicotine and nicotine salts with pungent odors, and a large amount of glycerin that can produce a smoke effect, and this needs to be improved. Summary of the Invention [Problem to be solved by the invention]

[0011] The main problem that the present invention aims to solve is to maintain the aroma that a user feels when using an electronic cigarette while reducing the amount of essence, essence solvent, and essence-related substances in an electronic cigarette that enters the human lungs. [Means for solving the problem]

[0012] In order to solve the above problems, the present invention provides a technical solution for an oral / nose electronic cigarette, which comprises an oral inhalation electronic cigarette module and a nasal inhalation module, the oral inhalation electronic cigarette module being one of a vapor electronic cigarette and a heat-not-burn electronic cigarette, the nasal inhalation module being disposed on the outside or inside of the oral inhalation electronic cigarette module, and the nasal inhalation module being equipped with at least one essence mounting body in which an essence is disposed.

[0013] In some mouth-breathing electronic cigarette modules, the transmission path from the person's mouth of the atomized aerosol generated by liquid tobacco tar or the smoke generated by solid tobacco cartridges or tobacco paste remains, and by providing a separate nasal breathing module as a direct transmission path for the essence or aroma to the person's nose, simultaneous smoking through two passages, mouth and nose, is possible with the electronic cigarette. However, by transferring part or all of the liquid tobacco tar and essence in the solid tobacco cartridge or tobacco paste that was previously added to the mouth-breathing electronic cigarette module to the nasal breathing module, and releasing the aroma from the essence in the nasal breathing module at room temperature or when slightly heated, the aroma molecules in the nasal breathing module are transmitted directly to the person's nose without entering the oral cavity.

[0014] In a preferred embodiment of the present invention, the vapor electronic cigarette includes a high-power electronic cigarette, a low-power electronic cigarette, a CBD electronic cigarette, an open-type electronic cigarette, a closed-type electronic cigarette, an ultrasonic atomization electronic cigarette, a disposable non-reloadable vapor electronic cigarette, and a reloadable vapor electronic cigarette, and the heated non-combustion electronic cigarette includes a heated non-combustion electronic cigarette that consumes a solid tobacco cartridge, and a heated non-combustion electronic cigarette that consumes a paste-like tobacco material.

[0015] So far, the above-mentioned vapor electronic cigarettes and heat-resistant electronic cigarettes only have a mouth-breathing electronic cigarette module, and the assembly of the mouth-breathing electronic cigarette module can be divided into four sub-modules: a nozzle module, an atomization and heating module, a circuit module, and a display module, but:

[0016] The nozzle module includes an assembly such as a nozzle or a filter,

[0017] The atomization and heating modules are classified into: [1] tobacco tar resistive atomization modules (which are equipped with an assembly including an empty atomization cartridge, an oil reservoir, liquid tobacco tar, a cotton atomization core or a ceramic atomization core, an air mist passage, an atomization cartridge base with a magnetic column and an electrode head); [2] ultrasonic atomization modules or piezoelectric ceramic atomization modules; and [3] HNB resistive heating modules (which are equipped with an assembly including a heating sheet, a heating rod, a heating tube, a heating pot, etc., a heating element base with an electrical connection port, a tobacco cartridge, a tobacco cartridge sleeve, and a tobacco cartridge base).

[0018] The circuit module includes an assembly including a PCB board, a TCR thermostat, a microphone sensor, a temperature sensor, an indicator light, a switch and a level controller, a battery, a wire port, and wires.

[0019] The display module comprises an assembly including a data collector and a display screen; the display screen is not an essential module for an electronic cigarette, but some control elements, such as a control element for selecting the output power, may be integrated into the display module.

[0020] In the present invention, a nasal breathing module is added to the oral breathing electronic cigarette module, and the nasal breathing module may or may not be connected to the circuit module and display module in the above four sub-modules of the oral breathing electronic cigarette module.

[0021] In a preferred embodiment of the present invention, the essence includes, but is not limited to, one or a combination of multiple types of fruit peel, fruit, fruit essence, refreshing essence, sweetener essence, tobacco essence, meat essence, alcohol essence, food essence, plant herb essence, animal flavor essence, biosynthetic flavor essence, and microbial fermentation flavor essence.

[0022] Specifically, the cooling agent essence may include, for example, menthol essence, WS-23 (N-ethyl-L-menthylcarboxamide) essence, and WS-3 (mentholamide) essence. The sweetener may include, for example, sucralose essence, and neotame essence. The fruit essence may include, for example, linalool essence, β-damascene essence, and passion fruit essence. The tobacco essence may include, for example, tobacco extract. The meat flavor essence may include, for example, animal fats and oils, and artificial ethyl maltol.

Examples of biosynthesized flavor essences include vanillin and 2-phenylethanol synthesized by biotransformation. Examples of microbial fermented flavor essences include acid-based essences, alcohol-based essences, ketone-based essences, lactone-based essences, etc. The substance added to the nasal inhalation module together with the essence may be a small amount of solvent that accompanies the essence, such as water, propylene glycol, medium-chain triglyceride, or glyceryl caprylate.

[0023] In a preferred embodiment of the present invention, a component fixing device for fixing the nasal breathing module to the outside or inside of the oral breathing electronic cigarette module is further provided, and the component fixing device includes components such as, but not limited to, double-sided tape, tape, adhesive, rope, clamp, locking hole, magnetic body, screw, and fixing ring.

[0024] In a preferred embodiment of the present invention, the essence mounting body is one or a combination of a plurality of the following: an essence bottle, an essence pot, an electric heating plate, and an electric heating pot; and the electric heating plate is a micro-mesh type electric heating plate or a non-mesh type electric heating plate that integrates a resistive heating element.

[0025] In addition, in order to make it easier to open and close these essence mounting bodies from the outside of the lid hole corresponding to the chamber lid, the height of the essence bottle lid, essence pot plug, and sealing lid of the electric heating pot that fit the essence mounting body may be appropriately increased.

[0026] In addition, the chamber lid may be provided with a push switch that can control the air outlet valve of the sealing lid of the essence pot, allowing the user to directly control the release of the essence scent in the essence pot from the outside without having to open the chamber lid and remove the sealing lid of the essence pot.

[0027] In a preferred embodiment of the present invention, the oral electronic cigarette module is provided with a first battery, and the nasal module may share the first battery with the oral electronic cigarette module, or the nasal module may be provided with a second battery, and the nasal module may not use a battery. The second battery may be a rechargeable battery or a disposable battery, and if the second battery is a rechargeable battery, a charging port corresponding to the new battery must be provided on the smoking tool.

[0028] In a preferred embodiment of the present invention, the nasal suction module further includes an electric heater controller, the first battery or the second battery is connected to the electric heater controller to supply power, and the electric heater controller is connected to a heating element in the essence mounting body to perform heating control.

[0029] In a preferred embodiment of the present invention, the nasal inhalation module further includes a fan controller and a fan corresponding to the essence mounting body, the first battery or the second battery is connected to the fan controller to supply power, and the fan controller is connected to the fan to control its operation. The electric heater controller and the fan controller may be integrated on the circuit board of the oral inhalation electronic cigarette module or the nasal inhalation module, or may be a normal electric switch such as a micro knob switch, a key switch, or an induction switch, which allows the activation / deactivation control of these electric devices and the adjustment of their operation levels. In order to facilitate user operation from the outside of the tobacco rod, these controllers may be partially or entirely provided on the chamber cover through a positioning cavity.

[0030] In addition, in some specific examples, the second battery may be connected to the fan and electric heater in the nasal inhalation module as well as some of the electrical and electronic elements in the oral inhalation e-cigarette module (such as PCB, microphone or sensor), and when the second battery is connected to all of the electrical and electronic elements in the oral inhalation e-cigarette module, the second battery corresponds to the first battery.

[0031] In a preferred embodiment of the present invention, the case of the mouth-breathing electronic cigarette module is provided with a chamber corresponding to the nasal-breathing module, and the nasal-breathing module is provided in the chamber;

[0032] However, the nasal module may be provided adjacent to the tobacco cartridge inside the electronic cigarette rod in the oral electronic cigarette module. At present, both reloadable vape e-cigarettes and HNB e-cigarettes provide a chamber at the head of the tobacco rod to facilitate the insertion of the tobacco cartridge in order to connect the respective tobacco cartridges, but there is no remaining space in the chamber after the tobacco cartridge is inserted. In order to embed the nasal module, the tobacco rod housing needs to be extended toward the tobacco cartridge to lengthen the chamber by 10-100 mm at the connection point, and then the base of the vape e-cigarette with the magnetic pole and electrode head or the base of the heating element of the HNB smoking tool and the electric wires need to be correspondingly moved forward in the tobacco rod connected to the tobacco cartridge, so that the chamber space for the nasal module, which is 10-100 mm long and has a height and width approximately equal to that of the tobacco rod, is left. In order to operate from the horizontal direction of the tobacco rod, the assemblies of the essence mounting body, the fan, the electric heater, and the battery in the snorting module are embedded and fixed in the chamber in sequence, and to facilitate control from the outside, a positioning cavity for the controller such as the fan and the electric heater may be provided in the chamber housing. A chamber cover may be made on the tobacco rod housing, and the assemblies of the essence mounting body, the fan, the electric heater, and the battery in the snorting module are embedded and fixed in the chamber in sequence, and to facilitate control from the outside, a positioning cover hole for the controller such as the fan and the electric heater may be provided in the chamber cover. Moreover, the appearance consistency of the tobacco rod housing can be maintained by passing the chamber cover through the sealed chamber of the locking groove.

[0033] However, the snorting module may be provided in the middle of the interior of the electronic cigarette rod. First, the normal vapor electronic cigarette rod and the HNB electronic cigarette rod are lengthened by 10-100 mm, and then the corresponding assemblies of the existing atomization and heating module, the circuit module and the display module in the tobacco rod are adjusted to be close to both ends of the tobacco rod, leaving a chamber space for the snorting module in the middle of the tobacco rod, which is 10-100 mm long and has a height and width approximately equal to that of the tobacco rod. The position adjustment of the tobacco rod relative to the internal assembly is a task that can be performed by those skilled in the art without creative labor. After opening the chamber lid, the assemblies such as the essence mounting body, the fan, the electric heater and the battery in the snorting module are sequentially embedded and fixed in the chamber by operating from the vertical direction of the tobacco rod, and the positioning lid holes for the controllers such as the fan and the electric heater are provided in the chamber lid to facilitate control from the outside.

[0034] However, the fan in the nasal suction module may be a micro floor-mounted electric fan with an integrated motor, or a panel-type or desk fan.

[0035] In a preferred embodiment of the present invention, the nasal suction module further includes an airway. In order to facilitate the connection and extension of the airway, an airway assembly may be configured by designing an airway port and an airway extension tube. The airway assembly has one end adjacent to the essence mounting body, or directly or indirectly connected to the essence mounting body. The airway assemblies are connected or disconnected by corresponding screws, sockets, and other structures. The airway may adopt a molded single tube, a plug-in multi-section tube, a telescopic sleeve type or a flexible universal tube, or may adopt the appearance of an elephant's trunk, a cartoon nose, an animal, a plant, a round hole, a square, a doll, a trademark, etc., to enhance the aesthetics and recognition of the airway assembly and the electronic cigarette.

[0036] The technical principle of the present invention is that the mouth and nose are important passages for the human body for inhalation and exhalation, and they can breathe independently or in concert, and when they breathe in concert, they can breathe simultaneously and synchronously. Most of the essences are small organic molecules that are naturally volatile, such as hydrocarbons, alkenes, alcohols, aldehydes, ethers, ketones, acids, phenols, esters, terpenes, sulfur-containing compounds, and nitrogen-containing compounds, with molecular weights of less than 300. Heating and blowing can both increase the volatilization rate of the essences. The olfactory nerves of the human body, which sense aromas, are mainly concentrated in the two nasal cavities. The mechanism of the human body's sense of smell can be briefly explained as follows: the aroma is recognized by the "receptors" in the nasal epithelium tissue, and a "mirror" nerve signal is generated and transmitted to the brain. Different aromas generate different "mirror" nerve signals, so that the brain can recognize specific aromas. The characteristic of the olfactory system is that its nerves are directly connected to the brain without being transmitted to the brain via the central nervous system, that is, the "aroma-nasal cavity-brain" is the fastest direct olfactory recognition pathway. In the present application, an electronic smoking tool is provided with a nasal inhalation module, and when the atomized aerosol or smoke generated by the oral electronic cigarette module is inhaled into the mouth passage of a person, the aroma of the essence released by the nasal inhalation module is simultaneously inhaled directly into the nose of the person, thereby improving the efficiency of transmitting the aroma molecules to the nasal cavity. Moreover, since there are fewer interference substances when the essence molecules in the nasal inhalation module enter the nasal cavity, it is easier for the olfactory nerve to accurately identify the essence, and the reproducibility of the taste of the electronic cigarette is improved. In addition, since the human nose does not have a swallowing function like the human mouth, the aroma, essence solvent, and essence-related substances are captured by the nasal hairs and nasal mucosa after entering the nasal cavity, and are less likely to enter the human lungs, thereby improving the safety of using the essence of the electronic cigarette.

[0037] The essence in the nasal inhalation module can evaporate naturally at room temperature, and can evaporate quickly when it is slightly heated. This slightly heated temperature is usually lower than the atomization temperature of e-cigarette tar and the heating temperature of HNB solid tobacco cartridges and tobacco paste. When the aroma of the essence in the nasal inhalation module is inhaled through the nose at a relatively low temperature, not only can the physiological activity of the essence molecules be maintained, but also the risk of the essence, essence solvent, and essence-related substances being decomposed into harmful substances such as formaldehyde at high temperatures can be reduced.

[0038] What the inventors unexpectedly found is that after the essence is transferred partially or completely from the oral electronic cigarette module to the nasal module, the taste reproduction of the electronic cigarette is obviously improved.The reason for the analysis is that there are only essence-related substances in the nasal module, and the aroma of the essence is directly transmitted to the nasal cavity, that is, when the aroma molecules are sensed by the human nasal olfactory nerve, there are relatively few other interfering substances around, so that the aroma characteristics can be accurately identified and the taste reproduction of the electronic cigarette can be improved.

[0039] What the inventors unexpectedly found is that after the essence is transferred from the liquid tobacco tar to the nasal module in part or in whole, some of the tobacco tar becomes clearer and more transparent.The reason for the analysis is that many essences in liquid tobacco tar are obtained by squeezing plants or extracting from organic solvents, and the terpene essences contained therein have strong and unique aromas and can improve the aroma characteristics of vaping electronic cigarettes, but these terpene essence molecules have very low solubility in liquid tobacco tar and are prone to precipitation, which causes serious appearance problems such as turbidity of liquid tobacco tar and the formation of layered floating oil, so more solvents or other new solvents must be added to the tobacco tar to dissolve and dilute the terpene essences, which not only reduces the aroma concentration of the essences, but also these essence solvents pose a safety threat to the lungs. In the present invention, after such poorly soluble essences are partially or completely transferred to the nasal inhalation module, not only is the risk of the essence and essence solvent entering the lungs through the mouth reduced, but the liquid tobacco tar becomes clearer and more transparent than before due to the reduction in terpene essences, improving the quality of appearance.

[0040] What the inventors unexpectedly discovered is that after the essence is transferred partially or completely from the oral electronic cigarette module to the nasal electronic cigarette module, the essence-related substances that come into direct contact with the atomizing core or heating element at high temperatures are reduced, thereby obviously improving the problems of carbon deposition and core paste on the atomizing core or heating element that have long plagued electronic cigarette users.

[0041] What the inventors unexpectedly found was that the nasal module can increase the variety of essences available for electronic cigarettes, since the safety risk of essence-related substances entering the lungs through the mouth is reduced after the essence is transferred partially or entirely from the oral electronic cigarette module to the nasal module, for example, the nasal module uses meat flavor essences or alcohol flavor essences, or tobacco essences in the form of a paste with a strong tobacco tar flavor, whereas the conventional electronic cigarette technology is difficult to use such essences due to poor appearance transparency or difficulty in applying essences. In addition, the transfer of essences from the oral electronic cigarette can also reduce the difficulty of applying essences to tobacco raw materials such as tobacco tar, solid tobacco cartridges, and tobacco paste, and simplify the production process.

[0042] The distinction between the present invention and conventional e-cigarette and snuff technology is as follows.

[0043] [1] In the present invention, the essence in the nasal module is inhaled by the human nasal passage, and the essence can be inhaled into the human nose even when it is at room temperature or slightly heated, whereas in the conventional technology of electronic cigarettes, the essence material needs to be heated to 180-380°C together with the atomized liquid or solid tobacco cartridge or tobacco paste, and then inhaled into the human body by the oral electronic cigarette module, which is at risk of degradation at high temperatures. The present invention helps to maintain the original flavor and biological activity of the essence.

[0044] [2] In current technology, the aroma of electronic cigarettes is inhaled from a person's mouth together with the atomized aerosol of a cigarette cartridge, and passes through the small circulation of "oral mucosa" or the large circulation of "oral mucosa-throat-trachea-bronchi-lung-bronchi-trachea-throat-oral mucosa", and then exhaled from the nasal cavity or the person's mouth, and is sensed by the olfactory nerve in the nasal cavity. Meanwhile, the aroma of the essence of the nasal inhalation module in the electronic cigarette of the present invention is inhaled in the nasal cavity and quickly sensed by the olfactory nerve, thereby improving the efficiency of delivery of essence molecules to the nasal cavity and the accuracy of identification.

[0045] [3] Conventionally, e-cigarettes involve inhaling atomized aerosol or smoke only through the mouth, and snuff involves inhaling granules of tobacco material only through the nose, i.e., conventional e-cigarette technology and snuff are single-passage inhalation devices. In contrast, the e-cigarette of the present invention has dual-passage inhalation devices that can be used simultaneously through both the mouth and nose.

[0046] [4] In snuff, what is inhaled directly into the nasal cavity is solid granules made of crushed substances such as tobacco leaves and lime powder, which is likely to damage the nasal mucosa and olfactory nerves and cause a lot of harm to the nose. In contrast, in the electronic cigarette of the present invention, what is inhaled directly into the nasal cavity from the nasal inhalation module is essential gas, which is soft and comfortable and causes less harm to the nose.

[0047] [5] In the patent application CN201310228824.X, the inhalation passage of the human mouth is completely abandoned, and the "fume" is inhaled directly through the human nose, which has the dual characteristics of "smoke" and "fog". In contrast, in the dual inhalation passage of the mouth and nose division and cooperation of the present invention, the essence aroma is inhaled directly through the human nose, and the essence aroma does not have the appearance of fog, so there is an obvious difference in the inhaled material and visual effects of the two. Effect of the Invention

[0048] The beneficial effects of the present invention are as follows: In other words, the oral-nasal electronic cigarette as indicated in the present invention can transfer the essence material in liquid tobacco tar or tobacco paste to the nasal inhalation module in part or in whole, and when the atomized aerosol or smoke of the electronic cigarette is inhaled from the mouth of a person, the aroma molecules of the essence in the nasal inhalation module can be directly inhaled into the nasal cavity, improving the utilization rate of the essence, the efficiency of the delivery of the aroma molecules to the olfactory nerve of the nasal cavity, and the identification accuracy, reducing the risk of using electronic cigarettes caused by oral introduction of essence, essence solvent, essence by-products, and uncertain impurities in the essence production process into the lungs, improving the problems of carbon deposition and core paste of the atomized core or heating element, and increasing the types of essences available for electronic cigarettes by the nasal inhalation module, which is helpful in simplifying the essence-adding process of tobacco raw materials such as tobacco tar, solid tobacco cartridges, and tobacco paste.

[0073] Example 5: Oral-nasal reloadable electronic cigarette, all essence and essence solvent are transferred to the nasal module.

[0074] The tobacco tar F is prepared by removing the cooling agent essence, passion fruit essence, sweetener essence, and propylene glycol and glycerin as essence solvents from the tobacco tar A. The mass ratio of each component of the tobacco tar F is set to 3% nicotine and 99.7% water in sequence, and 2 ml of the tobacco tar F is injected into an empty atomizing cartridge (sealed type) without a self-filling port, and the existing tobacco rod housing is extended 100 mm toward the atomizing cartridge to form a long chamber, and the atomizer circuit (504) and the base (505) on which a pair of base magnetic poles (506) and a pair of base needle electrodes (507) are provided are moved forward 100 mm toward the atomizing cartridge to correspond to the positions of the atomizing cartridge magnetic poles (526) and the atomizing cartridge electrode head (527). The mouth-breathing electronic cigarette module, which is composed of the atomizing cartridge (500), the extended tobacco rod (501), and the microphone, PCB board, first battery (502), first battery end wire port (503), and the extended wire in the existing circuit module, can normally atomize the tobacco tar F of the reloadable electronic cigarette, and the atomized aerosol can be inhaled by mouth. As shown in Figures 11 and 12, the first battery endTwo electric wires (525) are drawn out from the electric wire port (503) to connect the electric heating plate (509), electric heating plate knob switch (514), fan (519), and fan knob switch (520) provided in the chamber. In order to facilitate the user to control the electric heating plate and the fan from outside the tobacco rod, the cavities (515) and (521) in the housing of the extended tobacco rod (501) are made to correspond to the positions of these two knob switches. The electric heating plate (509) is sequentially provided with an essence spot fixing ring (511), an essence spot (510), and an elongated essence spot plug (512). Here, the essence spot fixing ring is fixed to the electric heating plate by a screw, and the essence spot plug (512) extends outside the tobacco rod through the alignment cavity (513) of the housing of the tobacco rod, and an appropriate amount of liquid mung bean essence and sweetener neotame essence are added to the essence spot. An essence bottle (516) with a screw cap is embedded and fixed in the chamber, and an elongated essence bottle cap (517) with a corresponding screw extends outside the tobacco rod through an alignment cavity (518) in the tobacco rod housing. A user can add an appropriate amount of bulk essence to the essence bottle by opening and closing the essence pot plug and the essence bottle cap from the outside of the tobacco rod. An opening for the chamber is further provided in the tobacco rod housing as an air tube port (523), and an air tube and an air tube extension tube are also provided and connected to each other by a screw previously installed at the tip. The components such as the electric heating plate, essence, essence pot, essence pot plug, essence bottle, essence bottle cap, fan, knob switch, electric wires, and air tube assembly constitute the snorting module (15).When using the electronic cigarette, the user may inhale the atomized aerosol generated by the atomized tobacco tar F of the mouth-breathing electronic cigarette module through his / her mouth, and may open the essence spot plug and the essence bottle cap to release the mung bean essence, sweetener essence, and rose essence from the three air outlets, namely, the housing cavity (513) aligned with the essence spot plug, the housing cavity (518) aligned with the essence bottle cap, and the air guide tube assembly (523, 522, 524); or, the user may cover the two aroma outlets, namely, the cavity (513) of the essence spot plug and the cavity (518) of the essence bottle cap with his / her fingers to release the mixed essence aromas individually from the outlets of the air guide tube assembly, and adjust the speed and temperature of the essence in the chamber that enters the user's nasal cavity by opening the electric heating plate knob switch (514) and the fan knob switch (520) from the outside of the tobacco rod, thereby achieving the combined mouth-nose use of the electronic cigarette.

[0075] Example 6: HNB e-cigarette for oral and nasal use, with some essence transferred to the nasal module.

[0076] A typical HNB smoking device using a solid tobacco cartridge is purchased from the market, and the assembly of the mouth-breathing electronic cigarette module mainly includes a filter (600), a solid tobacco cartridge (601), a tobacco cartridge sleeve (602), a heating element base (603), a heating element (604), a heating element (605), a heating element (606), a heating element (607), a heating element (608), a heating element (609), a heating element (610), a heating element (611), a heating element (612), a heating element (613), a heating element (614), a heating element (615), a heating element (616), a heating element (617), a heating element (618), a heating element (619), a heating element (620), a heating element (621), a heating element (622), a heating element (623), a heating element (624), a heating element (625), a heating element (626), a heating element (6 electricityThe device includes a port (605), a first battery (606), a first battery end wire port (607), a heating element circuit (608), a first battery charging port (609), and a heating element switch (620). A user can normally inhale smoke generated by heating a solid tobacco cartridge that contains only a small amount of essence material (such as a smoke flake tobacco cartridge made of nicotine extracted from plants and a small amount of tobacco essence) by using the solid tobacco cartridge. As shown in FIG. 13 and FIG. 14, a double-sided tape (610) that is approximately the same width as the smoking device is attached to the surface of the smoking device slightly lower than the heating element switch (620). A second battery (611), a second battery end wire port (612), a fan (615), a fan knob switch (614), a heating plate (616), and a heating plate knob switch (617) are sequentially attached to the surface of the double-sided tape. Two electric wires (613) are drawn out from the second battery end electric wire port (612) to respectively connect the fan, the fan knob switch, the electric heating plate, and the electric heating plate knob switch. The two essence bottles are fixed to the electric heating plate with screws. The first essence bottle (618) is filled with an appropriate amount of tobacco essence, and the second essence bottle (621) is filled with an appropriate amount of alcohol-smelling essence. The second battery, the electric heating plate, the fan, the essence bottle, the knob switch, and the double-sided tape constitute the snorting module (15) exposed to the housing of the HNB tobacco rod. When using the electronic cigarette, the user inhales the smoke generated by the mouth-breathing electronic cigarette module of the HNB smoking device through the mouth, and opens the first essence bottle (619) and the second essence bottle (622) to allow the essence aroma volatilized in the two essence bottles to enter the user's nasal cavity directly, or the user can open and control the fan knob switch and the electric heating knob switch to adjust the speed and temperature of the essence aroma in the two essence bottles entering the nasal cavity, thereby achieving the combined mouth-nose use of the electronic cigarette.

[0077] Example 7: Oral and nasal combined HNB e-cigarette, the whole essence is transferred to the nasal module.

[0078] After extending the housing of Comparative Example 2 or a similar HNB smoking device by 50 mm and fine-tuning the positions of the existing circuit module and atomization / heating module (PCB board, wires, temperature sensor, etc.) inside the HNB tobacco rod, an open chamber (725) with a length of 50 mm, a width of 12 mm, and a center depth of 10 mm is created in the middle of the tobacco rod (726), and the open chamber can be opened and closed by a chamber cover (719) and a chamber cover locking groove with corresponding dimensions. The assembly of the mouth-breathing electronic cigarette module of this HNB smoking device mainly includes a filter (700), a solid tobacco cartridge (701), a tobacco cartridge sleeve (702), a heating element base (703), a heating element (704), a heating element electrical port (705), a first battery (706), a first battery charging port (707), a first battery end electrical wire port (708), a heating element circuit (709), and a heating element switch (710). By using a solid tobacco cartridge that does not contain essence material (for example, a smoke granule tobacco cartridge made of synthetic nicotine without adding essence), the user can normally inhale the smoke generated by the solid tobacco cartridge being heated by a heating element. As shown in Figs. 15 and 16, a fan (712), an electric heating plate (711), an essence pot fixing ring (716), an essence pot (717), and an essence pot sealing cover (718) with an air outlet valve are sequentially embedded and fixed in the chamber. Two electric wires are drawn out from the first battery end electric wire port (708) to respectively connect the fan (712), the fan knob switch (714), the electric heating plate (711), and the electric heating plate knob switch (713). To facilitate user control of the electric heating plate and the fan from outside the chamber, the user-operated portions of the two knob switches are fixed to the chamber lid (719) by the alignment cover hole (723) of the electric heating plate knob switch on the chamber lid and the alignment cover hole (724) of the fan knob switch on the chamber lid. The chamber lid is provided with a push switch (720) for turning on the outlet valve of the essence pot sealing cover. An appropriate amount of a mixture of opaque paste-like heat-dried tobacco tar flavored tobacco essence and solid musk essence is added to the essence pot.After the essential pot sealing lid (718) is closed, the outlet valve of the essential pot sealing lid can be opened and closed by the push switch (720) on the chamber lid (719). The push switch (720) and the outlet valve of the essential pot sealing lid are simplified to a lift rope and a valve similar to the exhaust valve of a rice cooker sealing lid or a pressure cooker sealing lid, and the outlet valve can be opened and closed by the lift rope.

[0079] In this embodiment, the chamber cover (719) is further provided with an air guide tube (721), which is connected to the air guide tube extension tube (722) by a screw at the end. The electric heating plate, the essence pot, the essence pot sealing cover with the air outlet valve, the push switch of the air outlet valve, the fan, the knob switch, and the air guide tube assembly constitute the nasal inhalation module (15), which shares the first battery with the mouth-inhalation electronic cigarette module. When using the electronic cigarette, the user inhales the smoke generated by the mouth-inhalation electronic cigarette module of the HNB smoking device through the mouth, and opens the air outlet valve of the essence pot sealing cover by the push switch (720) on the chamber cover, so that the essence gas in the essence pot can be drawn into the user's nasal cavity through the air guide tube (721) and its extension tube (722).

[0080] Effect of the invention: In the first and sixth embodiments, the inhalation module is fixed to the housing of the electronic smoking tool by double-sided tape and screws, etc. In the second, third, fourth, and seventh embodiments, the housing of the smoking tool is appropriately lengthened to form a cavity in the middle of the tobacco rod, and the snoring module is embedded in the cavity. In the fifth embodiment, the chamber of the tobacco rod connected to the tobacco cartridge is appropriately lengthened, and the base, magnetic pole, electrode, and electric wire that cooperate with the atomizing cartridge are correspondingly moved forward, and then the snoring module is embedded in the extended chamber.

[0081] In the third, fourth and sixth embodiments, a second battery is added to the electrical device in the nasal breathing module. In contrast, in the second, fifth and seventh embodiments, the nasal breathing module shares the first battery with the mouth-breathing electronic cigarette module in the electronic smoking device. The nasal breathing module in the first embodiment does not use a battery.

[0082] In Examples 1 to 5, the flavor essence, sweetener essence, cooling agent essence, essence solvent propylene glycol, and essence solvent glycerin are sequentially removed from tobacco tar A. In Example 6, the HNB fixed tobacco cartridge contains only a small amount of essence. In Example 7, the HNB fixed tobacco cartridge does not contain any essence component. That is, in the present invention, from Examples 1 to 7, the essence and essence solvent used in the mouth-breathing electronic cigarette module are transferred partially or entirely to the nose-breathing module, so that the essence substances in the atomized aerosol and smoke entering the lungs from the mouth are greatly reduced or even reduced to zero, which is helpful in reducing the threat of essence, essence solvent, and essence-related substances to the human lungs, and improves the personal safety of electronic cigarette users.

[0083] Furthermore, by providing an electronic smoking device with a nasal inhalation module, users can directly and quickly inhale the aroma of the essence, and the efficiency of the delivery of the essence molecules to the nasal cavity of the human body can be improved. Moreover, these essences do not need to undergo a high-temperature atomization process together with tobacco tar, but can be vaporized and delivered to the nasal cavity of the human body at room temperature or with slight heating, with the aid of a fan and an air guide, which helps to maintain the original flavor and physiological activity of the essence material.

[0084] The user can not only continue to inhale the atomized aerosol and smoke generated in the oral module of this electronic cigarette through his / her mouth, but also inhale the aroma of the essence of the electronic cigarette released from the nasal module directly through his / her nose, thereby achieving the combined use of the dual inhalation passages of the mouth and nose of the electronic cigarette.

[0085] 20 experts in the field of vapor e-cigarette smoking conducted smoking evaluations on the above Comparative Example 1 and Examples 1-5. The overall opinion was that the e-cigarettes using the dual inhalation passages of the mouth and nose in Examples 1-5 provided a significantly better smoking experience than the e-cigarettes using the single inhalation passage of the human mouth in Comparative Example 1. In particular, in Examples 1-5, the user's nasal cavity can detect the aroma of the essence more quickly, improving the efficiency of the delivery of aroma molecules to the nasal cavity, and since there are fewer other interfering substances, the aroma can be quickly identified by the olfactory nerve, improving the reproduction of the flavor of the e-cigarette.

[0086] 20 experts as HNB e-cigarette smokers respectively performed smoking evaluation and comparison for the above Comparative Example 2 and Examples 6 to 7. According to the overall opinion, in Examples 6 to 7, although the solid tobacco cartridge contains little or no tobacco essence, after the tobacco essence is transferred to the nasal inhalation module, the aroma of tobacco, etc., emitted from the nasal inhalation module can be sensed and recognized by the human nose more quickly when smoking with both the mouth and nose, the efficiency of aroma transmission to the nasal cavity is improved, and the variety of available essences is increased; in particular, since the opaque paste-like heat-cured tobacco tar-based tobacco essence is used in the nasal inhalation module, the physiological experience during joint smoking of the dual passage tobacco between the mouth and nose is closer to that of a conventional heat-cured cigarette.

[0087] In addition, the oral-nose electronic cigarette according to the present invention does not limit the tobacco raw material in the oral electronic cigarette module. This tobacco raw material may contain nicotine and its derivatives such as nicotine salts, may be herbal tobacco raw material that does not contain addictive ingredients such as nicotine, or may be tobacco raw material that contains health care or pharmaceutical substances.

[0088] The above are merely examples of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by utilizing the contents of the specification of the present invention, or directly or indirectly applied to other related technical fields, shall be deemed to be included in the patent protection scope of the present invention.
