Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an electronic cigarette with a rifling one-way gas valve. Background Technology

[0002] Currently, in existing e-cigarettes, when the vapor produced by the heating element in the airway heats the e-liquid, it is expelled through the airway in the mouthpiece. However, the air resistance encountered during inhalation weakens the airflow, resulting in less vapor being expelled. This leads to a weaker airflow force and poor vapor flavor saturation. In addition, users often blow air into the airway while vaping. This reverse airflow passes through the airway and enters the air slot where the airflow switch is installed, activating the airflow switch. This causes the power supply component to power the heating element, heating the e-liquid, thus causing the e-cigarette to malfunction. Utility Model Content

[0003] The purpose of this invention is to provide an electronic cigarette with a rifled one-way air valve. By designing a one-way air valve and creating rifling in the airway, this invention solves the problems in the prior art where, when the smoke is expelled from the airway with the airflow, it encounters resistance from the outside air, resulting in weak airflow force, poor smoke flavor saturation, and the problem that reverse airflow can activate the internal airflow switch through the airway, causing the electronic cigarette to malfunction.

It should be noted that, provided there is no conflict, the various embodiments and features within them can be combined with each other, and all resulting technical solutions are within the protection scope of this utility model.

[0022] It should be noted that the specification of this application contains a large number of technical features distributed across various technical solutions. Listing all possible combinations of technical features (i.e., technical solutions) would make the specification excessively lengthy. To avoid this problem, the various technical features disclosed in the above-described utility model content, the various technical features disclosed in the following embodiments and examples, and the various technical features disclosed in the accompanying drawings can be freely combined to form various new technical solutions (all of which are considered to have been described in this specification), unless such a combination of technical features is technically infeasible.

Therefore, the solution A+B+C+D should not be considered as described because it is technically infeasible, while the solution A+B+C+E should be considered as described.

[0023] like Figure 1-4 As shown, this utility model provides an electronic cigarette with a rifling one-way air valve, including an electronic cigarette body 10. The electronic cigarette body 10 has an air sensor 120, a power supply component 130, an oil storage chamber 302 for storing e-liquid, and a ventilation and exhaust section 110 corresponding to the oil storage chamber 302. The ventilation and exhaust section 110 is provided with a one-way air valve 305 and multiple riflings 104, as well as a heating element 304 electrically connected to the power supply component 130 and extending into the oil storage chamber 302 at both ends. The air sensor 120 is provided with an airflow switch 8 that can activate the power supply component 130 to power the heating element 304 after air is vented. The electronic cigarette body 10 is provided with an air inlet 901 that communicates with the ventilation and exhaust section 110 and the air sensor 120. It should be noted that by designing rifling 104 and one-way air valve 305 inside the ventilation and exhaust section 110, the air resistance can be reduced when the smoke is discharged from the ventilation and exhaust section 110 through the rifling 104, which can make the smoke more explosive and flavorful. When there is reverse airflow entering the ventilation and exhaust section 110, the one-way air valve 305 can automatically close and block the ventilation and exhaust section 110 to prevent airflow from entering the air sensor section 120 and abnormally activating the airflow switch 8, which would cause the power supply component 130 to power the heating core 304 to heat the e-liquid.

[0024] In some embodiments, the heating element 304, the one-way air valve 305, and each rifling 104 are arranged sequentially from bottom to top in the ventilation and smoke exhaust section 110 along the direction of smoke discharge. The air sensor 120 and the air inlet 901 are located below the ventilation and smoke exhaust section 110. It should be noted that when smoking, the external airflow enters the air sensor 120 and the ventilation and smoke exhaust section 110 through the air inlet 901. After the airflow switch 8 senses the airflow in the air sensor 120, it can activate the power supply component 130 to power the heating element 304 to make it heat up, and heat the e-liquid in the oil storage chamber 302 to produce smoke. Then, the airflow drives the smoke generated by the heating element 304 heating the e-liquid in the ventilation and smoke exhaust section 110 through the one-way air valve 305, and then through the rifling 104 to reduce air resistance before being quickly discharged from the ventilation and smoke exhaust section 110 for the user to inhale.

[0025] In some embodiments, the ventilation and smoke exhaust section 110 is formed by an airway and / or an air pipe; the air sensor section 120 is formed by an air groove 703, an airway, or an air hole. In this embodiment, the ventilation and smoke exhaust section 110 is formed by an airway, and the good permeability of the airway allows for smoother airflow; in this embodiment, the air sensor section 120 is formed by an air groove 703 and an airway, the air groove 703 is used to accommodate the airflow switch 8, and the airway is used to guide the airflow into the air groove 703 to be sensed by the airflow switch 8.

[0026] In some embodiments, the one-way valve 305 is made of latex material, with a cylindrical lower end and a conical upper end. A cavity 306 is formed inside the one-way valve 305, and a vent 307 corresponding to and communicating with the cavity 306 is provided at the top of the one-way valve 305. The vent 307 is linear. The one-way valve 305 is made of latex material, which is soft and deformable under air pressure. When a directional airflow enters the ventilation and smoke exhaust section 110, the conical upper end of the one-way valve 305 can block the airflow and generate air pressure. The air pressure can deform the upper end of the one-way valve 305, thereby automatically closing the vent 307. Then, the directional airflow cannot pass through the vent 307, the cavity 306, and the ventilation and smoke exhaust section 110 in sequence to enter the air sensor 120, causing the airflow switch 8 to activate the power supply component 130 to supply power to the heating element 304.

[0027] In some embodiments, the electronic cigarette body 10 includes a cartridge 3, an oil storage chamber 302 is formed inside the cartridge 3, a first air tube 303 is provided inside the oil storage chamber 302, a first air passage 301 is formed inside the first air tube 303, the upper end of the first air passage 301 extends to the top of the cartridge 3, the lower end of the first air passage 301 extends to the bottom of the cartridge 3, a heating element 304 is provided at the lower end of the first air passage 301, and both ends of the heating element 304 penetrate through the wall of the first air tube 303 and extend into the oil storage chamber 302, a one-way air valve 305 is provided at the upper end of the first air passage 301, and an air inlet 307 communicates with the first air passage 301 through a cavity 306. The first air tube 303 is used to isolate the e-liquid in the oil storage chamber 302, and the first air passage 301 is used to allow airflow and exhaust smoke. The e-liquid in the oil storage chamber 302 can enter the heating core 304 through both ends of the heating core 304 and then be heated to produce smoke. The smoke can enter the cavity 306 in the first air passage 301 with the airflow and then be discharged from the upper end of the first air passage 301 through the air vent 307.

[0028] In some embodiments, the electronic cigarette body 10 further includes a mouthpiece 1, which is disposed at the top of the cartridge 3. The mouthpiece 1 has a smoking port 101 at its top. The mouthpiece 1 extends inward from the smoking port 101 to form a second air tube 102. The lower end of the second air tube 102 is inserted into the upper end of the first airway 301. A second airway 103 is formed inside the second air tube 102. The upper end of the second airway 103 is connected to the smoking port 101. The lower end of the second airway 103 corresponds to the upper end of the one-way valve 305. The second airway 103 communicates with the oral cavity through the air vent 307. Each rifling 104 is formed on the inner wall of the second air tube 102. The first airway 301 and the second airway 103 constitute a ventilation and smoke exhaust section 110. The mouthpiece 1 is used to inhale smoke by holding it in the mouth. The lower end of the second air tube 102 is inserted into the upper end of the first airway 301 to connect the first airway 301 and the second airway 103. When smoking, the smoke generated by the heating element 304 in the first airway 301 heating the e-liquid is discharged from the first airway 301 and the cartridge 3 through the cavity 306 and the air vent 307. It can then enter the second airway 103, and after passing through each rifling 104, the airflow speed is accelerated, and a large amount of smoke is carried out and enters the user's mouth. In some embodiments, the first airway 301 and the second airway 103, as well as the first air tube 303 and the second air tube 102, constitute the ventilation and smoke exhaust section 110.

[0029] In some embodiments, the electronic cigarette body 10 further includes a shell 2 and a support 7. The cartridge 3 and the support 7 are disposed inside the shell 2. An opening 201 is provided at the top of the shell 2. The upper end of the mouthpiece 1 extends out from the opening 201 and is exposed at the top of the shell 2. An air groove 703 is provided at the bottom of the support 7. An airflow switch 8 is disposed inside the air groove 703. A third air passage 702 is provided at the top of the support 7, which corresponds to and communicates with the air groove 703. The third air passage 702 is offset from the lower end of the first air passage 301. The air groove 703 and the third air passage 702 constitute the air sensor 120. The outer shell 2 is used to house the support 7 and the cartridge 3. The opening 201 is used to expose the mouthpiece 1 at the top of the outer shell 2 for easy smoking. When smoking, the external airflow enters through the air inlet 901 and then enters the air groove 703 through the third air passage 702. After the airflow switch 8 senses the airflow in the air groove 703, it activates the power supply component 130 to power the heating core 304. When the user blows air in the opposite direction into the second air passage 103 and the first air passage 301 through the mouthpiece 1, the upper end of the one-way air valve 305 will contract to close the air vent 307. The reverse airflow can be blocked in the second air passage 103 and will not pass through the air vent 307 and the cavity 306 in sequence, or enter the air groove 703 from the third air passage 702 through the first air passage 301, thus activating the airflow switch 8.

[0030] In some embodiments, the power supply assembly 130 includes a battery cell 4 and a power board 5. The battery cell 4 is also disposed within the housing 2, and the power board 5 is disposed at the bottom end of the bracket 7. The battery cell 4 is electrically connected to the power board 5, and the power board 5 is electrically connected to the airflow switch 8 and the heating element 304. Specifically, the battery cell 4 supplies power to the power board 5 to activate its electronic control function, the power board 5 supplies power to the airflow switch 8 to activate its airflow sensing control function, and the power board 5 also supplies power to the heating element 304 to generate heat.

[0031] In some embodiments, the electronic cigarette body 10 further includes a bottom shell 9, which is located at the bottom end of the outer shell 2 and corresponds to the support 7. The top end of the support 7 is recessed to form a ventilation groove 701 that corresponds to and communicates with the lower end of the first airway 301. The ventilation groove 701 also communicates with the third airway 702. Oil-absorbing cotton 6 is provided in the ventilation groove 701. The bottom end of the support 7 is also provided with an air inlet 704 that communicates with the ventilation groove 701. An air inlet 901 is located at the bottom end of the bottom shell 9 and corresponds to and communicates with the air inlet 704. The air inlet 901 communicates with the third airway 702 and the lower end of the first airway 301 through the air inlet 704 and the ventilation groove 701. Among them, the bottom shell 9 is used to seal the bottom end of the outer shell 2, the ventilation groove 701 is used to allow the air entering from the air inlet 901 to flow into the third air passage 702 and the air groove 703, as well as the first air passage 301. At the same time, the ventilation groove 701 is used to collect the condensate generated by the liquefaction of smoke in the first air passage 301, the oil-absorbing cotton 6 is used to absorb the condensate collected in the ventilation groove 701, and the air inlet 704 is used to connect the air inlet 901 and the ventilation groove 701.

[0032] The following detailed description uses preferred embodiments.

[0033] like Figure 1-4As shown, the electronic cigarette of this utility model includes: an electronic cigarette body 10, which includes: a mouthpiece 1, a shell 2, a cartridge 3, a battery 4, a power board 5, oil-absorbing cotton 6, a bracket 7, an airflow switch 8, and a bottom shell 9. The cartridge 3 has an oil storage chamber 302 for storing e-liquid. A first air tube 303 is provided within the oil storage chamber 302 to isolate the e-liquid. A first air passage 301 is formed within the first air tube 303 for airflow and smoke exhaust. The upper end of the first air passage 301 extends to the top of the cartridge 3, and the lower end extends to the bottom of the cartridge 3. A heating element 304 is provided within the lower end of the first air passage 301 for heating the e-liquid in the oil storage chamber 302. Both ends of the heating element 304 penetrate the wall of the first air tube 303 and extend into the oil storage chamber. The cavity 302 is used to absorb the e-liquid in the oil storage cavity 302. A one-way valve 305 is provided in the upper end of the first air passage 301 to allow airflow and smoke from bottom to top to pass through, while airflow from top to bottom cannot pass through. The air vent 307 communicates with the first air passage 301 through the cavity 306. The one-way valve 305 has a cavity 306 to connect with the lower end of the first air passage 301. The top of the one-way valve 305 has an air vent 307 that corresponds to and communicates with the cavity 306 to connect the upper end of the first air passage 301 and the cavity 306. The cartridge 3 and the bracket 7 are installed in the outer shell 2. The top of the outer shell 2 has an opening 201. The lower end of the mouthpiece 1 is inserted into the outer shell 2 through the opening 201 and abuts against the top of the cartridge 3. The upper end of the mouthpiece 1 protrudes from the opening 201 and is exposed in the outer shell 2. The tip is for holding in the mouth to smoke. The tip of the mouthpiece 1 has a smoking opening 101 for smoke exhaust. The mouthpiece 1 protrudes inward from the smoking opening 101 to form a second air tube 102. The lower end of the second air tube 102 inserts into the upper end of the first airway 301 to connect the mouthpiece 1 to the cartridge 3. A second airway 103 is formed within the second air tube 102, also for airflow and smoke exhaust. The upper end of the second airway 103 is connected to the smoking opening 101, and the lower end of the second airway 103 corresponds to the upper end of the one-way valve 305. The second airway 103 communicates with the oral cavity through the air vent 307. Multiple rifling grooves 104 are formed on the inner wall of the second air tube 102 to reduce air resistance when smoke is exhausted with the airflow, thereby increasing the explosive power and flavor fullness of the smoke. The battery 4 is also installed... The power board 5 is installed inside the outer casing 2 and mounted at the bottom of the bracket 7. The battery cell 4 is electrically connected to the power board 5 to supply power to the power board 5 and enable its electronic control function. The power board 5 is electrically connected to the heating element 304 to supply power to the heating element 304 to heat the e-liquid. The bottom of the bracket 7 has an air groove 703 to accommodate the airflow switch 8. The airflow switch 8 is installed in the air groove 703 to sense the airflow and activate the power board 5 to supply power to the heating element 304. The power board 5 is also electrically connected to the airflow switch 8 to supply power to the airflow sensing and control function. The top of the bracket 7 has a third air channel 702 that corresponds to and communicates with the air groove 703 to supply airflow into the air groove 703. The lower end of the third air channel 702 is offset from the lower end of the first air channel 301.To prevent condensate formed by smoke liquefaction in the first air passage 301 from entering the third air passage 702 and air groove 703, thus causing the airflow switch 8 to malfunction, the top of the bracket 7 is recessed to form a ventilation groove 701 that communicates with the lower end of the first air passage 301 and the third air passage 702. This groove allows airflow into the third air passage 702, air groove 703, and the first air passage 301. Simultaneously, the groove collects condensate generated by smoke liquefaction in the first air passage 301. Oil-absorbing cotton 6 is installed in the ventilation groove 701 to absorb the collected condensate. A bottom shell 9 is installed at the bottom of the outer shell 2 to seal the bottom of the outer shell 2. An air inlet 901 is provided at the bottom of the bottom shell 9 for external airflow to enter. The bottom of the bracket 7 also has an air inlet hole 704 corresponding to and communicating with the ventilation groove 701 and the air inlet 901 to connect the air inlet 901 and the ventilation groove 701.

[0034] like Figure 5 As shown, the specific implementation of the airflow and smoke direction of the electronic cigarette of this utility model is described. When smoking through the mouthpiece 1, the external airflow can enter the ventilation groove 701 through the air inlet 901 and the air inlet hole 704 in sequence, then enter the first air passage 301 and the third air passage 702 into the air groove 703. After the airflow is sensed in the air groove 703, the airflow switch 8 can activate the power board 5 to power the heating core 304. After the heating core 304 is powered on, it can heat the e-liquid in the oil absorption storage chamber 302 to produce smoke. The smoke can enter the cavity 306 of the one-way air valve 305 with the airflow entering the first air passage 301, and then enter the second air passage 103 from the upper end of the first air passage 301 through the air inlet 307. After the air resistance is reduced by each rifling 104, a large amount of smoke is quickly brought out from the smoking port 101 and enters the user's mouth to be inhaled.

[0035] like Figure 6 As shown, the working principle of the one-way air valve 305 of this utility model blocking reverse airflow is specifically explained. When the user blows air into the second airway 103 and the first airway 301 through the mouthpiece 1, the upper end of the one-way air valve 305 is conical, which can block the airflow and generate air pressure. The air pressure can deform the upper end of the latex-made one-way air valve 305, causing the air vent 307 to automatically close. Thus, the reverse airflow can be blocked in the second airway 103 and will not pass through the air vent 307 and cavity 306 in sequence, and the first airway 301 to enter the air groove 703 from the third airway 702. This causes the airflow switch 8 to sense the airflow and then start the power board 5 to power the heating core 304 to heat the e-liquid, thereby causing the electronic cigarette to malfunction.

[0036] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
