Description

[Technical field]

[0001] The present invention relates to an atomized electronic cigarette, and more particularly to an improved atomized electronic cigarette. [Background technology]

[0002] In the alternative smoking product market, aerosolized e-cigarettes account for a high proportion of tobacco substitutes, but the improvement and maturation of aerosolized e-cigarette technology is a prerequisite for the widespread adoption and acceptance of e-cigarettes.

[0003] At present, existing aerosol-type electronic cigarettes still have many problems and shortcomings, such as the atomization effect is not very good, and the final atomized smoke droplets have large and non-uniform particle sizes, which results in non-uniform smoke, too wet smoke, and poor mouthfeel, etc. In addition, under certain conditions, the smoke is not sufficiently cooled, which results in the smoke being inhaled at a high temperature, which makes the smoke uncomfortable for the smoker. Summary of the Invention [Problem to be solved by the invention]

[0004] The above problems create significant differences between real cigarettes and e-cigarettes for smokers, which does not encourage smokers to choose e-cigarettes as a substitute for real cigarettes. [Means for solving the problem]

[0005] In order to overcome various shortcomings of the prior art, in some embodiments of the present invention, an improved atomized electronic cigarette has a liquid-permeable component in an atomizer that is sleeve-like mounted on an electric heater. The tobacco liquid in the liquid storage component is permeated into the liquid-permeable component. The electric heater acts directly on the liquid-permeable component, so that the tobacco liquid is more effectively atomized with smaller and more uniform atomized or evaporated droplets. In another aspect, the electric heater and the liquid storage component are arranged with through-holes and channels that communicate with each other, and the larger atomized droplets are absorbed into the liquid storage component while being pushed by the airflow, so that the inhaled smoke is more similar to a real cigarette, to better satisfy the smoker's taste.

[0006] The main technical solutions in the embodiments of the present invention are as follows: The improved atomized electronic cigarette includes a power supply, a sensor, an atomizing core component, and a liquid storage component, and further includes a housing containing the above components. An auxiliary air inlet is arranged on the housing. One end of the housing is provided with an air suction port. The atomizing core component includes an electric heater, which can atomize the liquid in the liquid storage component. The liquid storage component has an internal passage through which the atomized gas flows and an auxiliary air inlet, and the sensor and the suction nozzle can form an airflow loop. A through-hole through which the gas flows from the internal passage with a passage wall may be formed in the liquid storage component, so that the atomized gas directly contacts the central part of the liquid storage component through the wall of the passage, and large particles of the atomized gas can be absorbed by contacting the liquid storage container. In addition, the sensor communicates with the passage and can form an airflow loop together with the auxiliary air inlet.

[0007] The present invention also uses the following related technical solutions: the atomizing core part includes a liquid-permeable part mounted on the electric heater in a sleeve-like manner, and a passage or through-hole through which gas flows is arranged in the atomizing core part, and the passage or through-hole is composed of the structure of the electric heater and the liquid-permeable part.

[0008] The electric heater of the atomizing core component may be inserted or extended directly into the passageway of the liquid storage component such that the atomizing gas flows directly through the passageway.

[0009] The body storage component may have therein hollow passages, through-hole passages, annular passages, or passages having an open mesh-like cross section, or combinations thereof, through which gas can flow.

[0010] The atomizing core component may further include a liquid conducting or transporting component in contact with the liquid permeating component and the liquid storage component.

[0011] The liquid conducting or transporting component may be sleeve-mounted on the liquid permeable component and may include a conductive portion extending radially from an end of the liquid conducting component and in contact with the liquid storage component.

[0012] The sensor may be an air pressure sensor or an air flow sensor. The housing may include a first housing and a second housing, the first housing having the power supply and the sensor located therein, and the second housing having the atomizing core component and the liquid storage component located therein. An auxiliary air inlet is disposed in an area of ​​the first housing and / or the second housing proximate to the sensor.

[0013] A bracket is disposed in the second housing, and the atomizing core part is fixed on the bracket. The electric heater is connected to the power supply and the sensor, and starts or stops heating according to the state of the gas flow through the sensor.

[0014] The air intake connection part and the electrode ring are disposed on the bracket, and the air intake part and the electrode ring are electrically connected to two leads of the electric heater, respectively. The air intake connection part is electrically connected to the sensor, and the electrode ring is electrically connected to the power supply device, through the air intake connection part and the sensor. The air intake connection part also has an air vent, and the sensor communicates with the air vent, the through hole and the passage, and forms an airflow loop with the auxiliary air intake.

[0015] The first housing and the second housing are joined by connecting the intake connection part and the sensor, and the intake connection part and the sensor are connected by joining, plugging, screws or tightening.

[0016] An air intake port is disposed on the second housing, and the sensor communicates with the vent, the passageway and the air intake port to form an airflow loop with the auxiliary air intake.

[0017] The housing may be an integrated or unified housing, the front end of which has an auxiliary air inlet, and the sensor communicates with the vents, through holes, passages and air intake ports, forming an airflow loop together with the auxiliary air intake.

[0018] The liquid-permeable component may be in contact with the liquid storage component. The atomizing core component may be sleeve-like mounted in the passage of the liquid storage component. The peripheral surface of the liquid-permeable component may be connected to the inner wall of the passage.

[0019] The liquid storage component may be a microporous ceramic, a foamed ceramic, a natural fiber, an artificial fiber or a foamed metal material. The liquid-permeable component may be a ceramic fiber, a quartz fiber, a glass fiber, an aramid fiber, a normal fiber, a paper, a cloth or a non-woven material. The electric heater may be formed by spirally winding an electric heating wire or may consist of an electric heating film arranged on the inner surface of the liquid-permeable component. The electric heater formed by spirally winding or the electric heating film on the inner surface of the liquid-permeable component may be hollowed out to form a through hole.

[0020] The thickness of the liquid-permeable part may be in the range of 0.5 to 5 mm, and the diameter of the through-hole may be in the range of 0.5 to 4 mm.

[0021] In the liquid-permeable component, zeolite particles may be added. Effect of the Invention

[0022] Aspects of the present invention can have the following beneficial effects. (1) In the present invention, the liquid-permeable part in the atomizing core part is directly attached on the electric heater in a sleeve-like manner, and the tobacco liquid in the liquid storage part can permeate into the liquid-permeable part. The thickness of the liquid-permeable part can be designed to be only 1 mm, and for example, the tobacco liquid permeating through the liquid-permeable part can be more easily completely atomized, evaporated, or vaporized by the electric heater when it is heated by the electric heater and vaporizes after reaching the boiling point. As a result, the vaporization of the liquid is more effective. For example, the droplets are smaller and more uniform, with a diameter of 0.04 micrometers to 0.8 micrometers. Such vapor is more similar to real tobacco smoke in terms of dispersion and appearance. Such vapor can easily enter the alveoli and be conveniently absorbed. On the one hand, the through holes and passages communicating with each other are arranged in the electric heater and the liquid storage part, so that the atomizing gas can smoothly pass through the liquid storage part. The larger droplets are then absorbed or deposited in the liquid storage component under air flow pressure, resulting in large particle vapor being delivered directly to the smoker, as is a common problem in the prior art. Thus, embodiments of the present invention create smoke upon inhalation that more appropriately satisfies the smoker's taste. (2) In another solution in some embodiments of the present invention, the atomizing core component is sleeve-like mounted in the passage of the liquid storage component, so that the liquid permeating component is in direct contact with the liquid storage component. The tobacco liquid can permeate and conduct more sufficiently and quickly, and can produce vapor or atomized smoke more effectively. In addition, the structure is simple and saves space, so that the overall volume of the atomized electronic cigarette can be smaller. (3) In another embodiment of the present invention, the electronic cigarette is designed to be detachable and replaceable, so that replacement of parts can be easily achieved by removing and reattaching the first and second housings. Such an electronic cigarette is convenient to carry and more portable. [Brief description of the drawings]

[0024] The present invention will now be described in detail with reference to the drawings.

[0025] As shown in Figures 1 to 5, the present invention provides an improved atomized electronic cigarette, which includes a power supply (power supply unit) 1, a sensor 2, an atomizing core component, and a liquid storage component 3, and further includes a housing containing the above components. An auxiliary air inlet (air intake) 4 is arranged on an area of ​​the housing close to the sensor 2. The atomizing core component includes an electric heater 5 and a liquid-permeable component 6 attached to the electric heater 5 in a sleeve-like manner. The electric heater 5 has a hollow structure and a through hole (hollow space) 51 through which gas flows. The liquid storage component 3 has a passage (channel) 31 inside through which gas flows. The passage may be a hollow passage, a through hole passage, an annular passage, or a passage having a cross-sectional structure with a locally coarse mesh structure, or a combination thereof, the purpose of which is to allow the atomized gas passing through the passage to contact the liquid storage core of the liquid storage component, and to allow the liquid storage component 3 to cooperate with the liquid-permeable component 6 to permeate the tobacco liquid into the liquid-permeable component 6. Furthermore, the sensor 2 communicates with the through hole 51 and the passage 31 to form an airflow loop together with the auxiliary air inlet 4.

[0026] 1 to 3, in an embodiment, the atomizing core component further comprises a liquid-conducting component 7 connected to the liquid-permeable component 6 and the liquid storage component 3. The liquid-conducting component 7 is attached to the liquid-permeable component 6 in a sleeve-like manner, and a conductive portion 71 extends radially from one end of the liquid-conducting component, and the conductive portion 71 contacts the liquid storage component 3. As a result, the tobacco liquid on the liquid storage component 3 is absorbed and permeates into the liquid-permeable component. In order to more firmly connect the liquid-conducting component 7 to the liquid-permeable component 6 and improve the liquid conductivity, a fastening sleeve 12 may be attached to the liquid-conducting component 7 in a sleeve-like manner.

[0027] As shown in FIG. 1, the sensor 2 can be an air pressure sensor or an air flow sensor. In an embodiment, an air flow sensor is used. The housing comprises a first housing 8 and a second housing 8', the power supply device 1 and the sensor 2 are located in the first housing 8, the aerosol core component and the liquid storage component 3 are located in the second housing 8', and the auxiliary air inlet 4 is located in an area of ​​the first housing 8 and / or the second housing 8' close to the sensor 2. In an embodiment, the auxiliary air inlet 4 is located on the first housing 8 in an area close to the sensor 2. The power supply device 1 is a battery, which may be a rechargeable battery or a disposable battery.

[0028] The bracket 9 is disposed in the second housing 8', the atomizing core part is fixed on the bracket 9, the electric heater 5 is connected to the power supply device 1 and the sensor 2, and starts or stops heating according to the state of the gas flow detected by the sensor 2. The inhalation connection part 10 and the electrode ring 11 are disposed on the bracket 9. The inhalation connection part 10 and the electrode ring 11 are electrically connected to the two lead wires of the electric heater 5, respectively. The inhalation connection part 10 achieves an electrical connection through the connection with the sensor 2 according to its function, and the electrode ring 11 is electrically connected to the power supply device 1 through the connection between the inhalation connection part 10 and the sensor 2. As shown in FIG. 4, a complete closed loop is formed. The function of the sensor is to switch on or off the entire circuit according to the gas flow. When the user inhales, the gas in the electronic cigarette flows. At this time, the sensor switches on the circuit and starts to heat the electric heater 5. When the user stops inhaling, the gas stops flowing, and the sensor switches off the circuit and stops heating the electric heater 5. An electrode ring post 13 corresponding to the electrode ring 10 is disposed in an opening of the first housing 8. A contact portion 131 extends axially from the electrode ring post 13. The electrode ring post 13 is connected to a power supply 1. When the first housing 8 and the second housing 8' are joined, the contact portion 131 is inserted into the second housing 8' and contacts the electrode ring 11, thereby forming a complete closed loop.

[0029] In this embodiment, the first housing 8 and the second housing 8' are connected through the connection of the inhalation connection part 10 and the sensor 2, and the inhalation connection part 10 and the sensor 2 are connected by splicing, plugging, screwing or tightening. With such a detachable and replaceable split structure, the replacement of parts can be easily achieved by removing and reattaching the first housing 8 and the second housing 8', making the electronic cigarette easy to carry and use. This embodiment discloses a screw connection structure.

[0030] 1, the intake connection part 10 also has an air vent 101, and the sensor 2 communicates with the air vent 101, the through hole 51, and the passage 31 to form an airflow loop together with the auxiliary air inlet 4. An air intake port a is disposed on the second housing 8', and the sensor 2 communicates with the air vent 101, the through hole 51, the passage 31, and the air intake port a to form an airflow loop together with the auxiliary air inlet 4.

[0031] The liquid storage part 3 is made of a liquid storage core material such as microporous ceramic, foamed ceramic, natural fiber, artificial fiber, or foamed metal material. The liquid permeable part 6 is made of ceramic fiber, quartz fiber, glass fiber, aramid fiber, general fiber, paper, woven fabric, or nonwoven fabric material. The thickness of the liquid permeable part 6 is in the range of 0.5 to 5 mm. The electric heater 5 is formed by winding an electric heating wire in a spiral shape, and the electric heater formed by winding in a spiral shape forms a through hole 51. The diameter of the through hole 51 may be in the range of 0.5 to 4 mm. In this embodiment, the thickness of the liquid permeable part 6 is 1 mm, and the diameter of the through hole 51 is 1 mm.

[0032] The liquid-permeable part 6 in the atomizing core part is directly attached to the electric heater 5 in a sleeve-like manner. The tobacco liquid in the liquid storage part 3 is permeated into the liquid-permeable part 6 by the liquid-conducting part 7. The thickness of the liquid-permeable part 6 is 1 mm. As a result, the permeated tobacco liquid can be more easily and completely vaporized by the electric heater 5. When the user inhales, the sensor 2 communicates with the vent 101, the through-hole 51, the passage 31 and the air inlet, forming an airflow loop with the auxiliary air inlet 4. When gas flow is generated in the electronic cigarette, the sensor 2 switches on the circuit, and the electric heater 5 starts to heat and vaporize the tobacco liquid in the liquid-permeable part 6 after it reaches its boiling point. At the same time, the electric heater 5 and the through-hole 51 and the passage 31 of the liquid storage part 3 are in communication with each other, so that the smoke generated during the atomizing procedure can be further cooled under the influence of the airflow, and finally inhaled into the user's oral cavity through the air inlet a.

[0033] In another preferred embodiment of the present invention, as shown in Fig. 6, the liquid-permeable part 6 is in contact with the liquid storage part 3. The atomizing core part is sleeve-like mounted in the passage 31 of the liquid storage part 3, and the peripheral surface of the liquid-permeable part 6 is coupled with the inner wall of the passage 31.

[0034] The liquid storage part 3 may be made of microporous ceramic, foamed ceramic, natural fiber, artificial fiber, or foamed metal material. The liquid-permeable part 6 may be made of ceramic fiber, quartz fiber, glass fiber, aramid fiber, general fiber, paper, woven fabric, or nonwoven fabric material. The thickness of the liquid-permeable part 6 is in the range of 0.5 to 5 mm. The electric heater 5 is formed by spirally winding an electric heating wire to form a through hole (hollow space) 51. The diameter of the through hole 51 may be in the range of 0.5 to 4 mm. In this embodiment, the thickness of the liquid-permeable part 6 is 1 mm, and the diameter of the through hole 51 is 1 mm.

[0035] In this embodiment, the atomizing core part is sleeve-mounted integrally in the passage 31 of the liquid storage part 3, so that the spherical surface of the liquid permeating part 6 directly contacts the inner wall of the passage 31 of the liquid storage part 3. Because the contact surface is larger, the permeation and conduction of the tobacco liquid is more sufficient and faster, and the atomized smoke is efficiently produced. At the same time, the structure is simple and space-saving, so as to minimize the size of the atomized electronic cigarette.
