Description

Technical Field

[0001] The present disclosure relates to the field of atomization technology, and in particular to an electronic cigarette. Background Art

[0002] An electronic cigarette (also called an "electronic cigarette") or a smoking device is an electronic delivery system for generating an aerosol from an atomized substrate for a user to inhale. The atomized substrate can be a liquid (e.g., a smoke liquid, etc.) or a solid or gel (e.g., a smoke paste), etc.

[0003] Generally, a conventional electronic cigarette mainly includes a cartridge storing an atomized matrix and a power supply device. The cartridge has a heating or evaporation device, such as an atomizer including an atomizer core. The power supply device supplies power to the atomizer core to convert the atomized matrix in the cartridge into an aerosol for the user to inhale. In many electronic cigarettes, the user's inhalation activates the atomizer core, vaporizing the liquid atomized matrix in the cartridge, and then the user inhales the generated aerosol through the mouthpiece.

[0004] The oil storage capacity of the cartridge is relatively small, and the time for users to smoke is relatively short, which leads to the problem of insufficient oil supply. If the oil supply for the cartridge is considered, the speed of oil supply is difficult to control, which may easily lead to oil leakage, and the oil supply speed is uneven and unstable, making it difficult to provide users with a stable smoking experience.

[0050] The embodiment of the present disclosure provides an electronic cigarette 100, comprising: an atomizing core 110, for atomizing the e-liquid to form smoke; a first oil storage bin 120, for providing the atomizing core 110 with e-liquid; a second oil storage bin 130, for replenishing the first oil storage bin 120 with e-liquid, and the second oil storage bin 130 is located outside the first oil storage bin 120. A through hole 121 is provided on the bin wall of the first oil storage bin 120, for connecting the first oil storage bin 120 and the second oil storage bin 130. The electronic cigarette 100 also includes a porous hard sheet 122, which at least partially covers the through hole.

[0051] See also Figure 1 and Figure 2The electronic cigarette 100 includes an atomizing core 110, a first oil storage bin 120, and a second oil storage bin 130. The atomizing core 110 is used to atomize the smoke oil to form smoke. The first oil storage bin 120 is arranged around the atomizing core, and is used to provide smoke oil for the atomizing core 110. The first oil storage bin 120 is provided with oil storage cotton 124 for storing smoke oil. The second oil storage bin 130 is arranged around the first oil storage bin 120, and is used to replenish the smoke oil for the first oil storage bin 120. A through hole 121 is provided on the bin wall of the first oil storage bin 120, which is used to connect the first oil storage bin 120 and the second oil storage bin 130, so that the smoke oil in the second oil storage bin 130 can flow into the first oil storage bin 120 through the through hole 121, so that the smoke oil can be supplied to the first oil storage bin 120 when the smoke oil in the first oil storage bin 120 is insufficient. The electronic cigarette 100 also includes a porous hard sheet 122, which at least partially covers the through hole 121.

[0052] By adding a second oil storage bin, the oil supply can be increased. At the same time, by arranging a porous hard sheet 122 at a position corresponding to the through hole 121 connecting the first oil storage bin 120 and the second oil storage bin 130, the speed of the second oil storage bin replenishing the oil to the first oil storage bin can be buffered, thereby buffering the speed of oil feeding into the atomizer core, avoiding oil leakage caused by excessive oil feeding, and improving the uniformity and stability of smoke output.

[0053] In some examples, the through hole 121 is disposed near the bottom of the peripheral wall of the first oil storage bin 120 so that the tobacco oil in the second oil storage bin 130 can be more fully absorbed by the oil storage cotton 124 disposed in the first oil storage bin 120 .

[0054] For some examples, see Figure 3 The wall of the first oil storage tank 120 is provided with stepped holes, which include a first hole 1291 with a smaller diameter and leading to the outside and a second hole 1292 with a larger diameter and leading to the inside, and the first hole 1291 and the second hole 1292 are connected. The first hole 1291 is used as a through hole 121, and the porous hard sheet 122 is embedded in the second hole 1292 and is closely attached to the first step 1293 between the first hole 1291 and the second hole 1292. The porous hard sheet 122 is located between the inner side of the wall of the first oil storage tank 120 and the oil storage cotton 124 of the first oil storage tank 120, and is closely combined with the oil storage cotton 124, so as to better play the role of buffering the oil inlet.

[0055] According to some embodiments of the present disclosure, the porous hard sheet 122 is a porous ceramic sheet, a porous mica sheet or other hard sheets with micropores, or a hard sheet with multiple micropores processed by laser or chemical etching.

[0056] According to some embodiments of the present disclosure, the thickness of the porous hard sheet is 0.5 mm to 2 mm. The porous hard sheet of this size can ensure that the tobacco oil in the second oil storage bin 130 can flow smoothly into the first oil storage bin 120.

[0057] According to some embodiments of the present disclosure, the porous hard sheet 122 is provided with at least one through hole 123, and the through hole 123 is at least partially connected to the through hole 121 to form a pressure relief hole. Figure 7 , the porous hard sheet 122 is provided with a through hole 123. When the through hole 121 is opened, by forming a pressure relief hole, when the user draws inhalation, a negative pressure is generated in the atomizer core and then in the first oil storage tank 120 surrounding the atomizer core, and the negative pressure causes the smoke oil in the second oil storage tank 130 to be pulled into the first oil storage tank 120 through the pressure relief hole; on the other hand, at the moment when the user finishes drawing inhalation, the pressure relief hole keeps the air pressure balance between the outer second oil storage chamber 130 and the inner first oil storage tank 120, so as to ensure smooth oil replenishment.

[0058] In some examples, most of the through hole 123 is staggered with the through hole 121, and only a small part is connected to the through hole 121 to prevent too much oil from entering the first oil storage tank 120 through the connecting part of the two, i.e., the pressure relief pore, causing excessive oil inflow.

[0059] For some examples, see Figure 7 The through hole 123 extends from the inside of the porous hard sheet 122 to the edge of the porous hard sheet 122. The through hole 123 designed in this way has a simple structure and is easy to process.

[0060] According to some embodiments of the present disclosure, the longitudinal dimension of the pressure relief aperture (see Figure 3 , that is, the dimension h) along the longitudinal direction of the electronic cigarette is 0.05mm-0.15mm, for example 0.1mm. This dimension can meet the requirement of maintaining the air pressure balance between the first and second oil storage bins, and will not cause the tobacco oil in the second oil storage bin to enter the first oil storage bin too quickly.

[0061] According to some embodiments of the present disclosure, the electronic cigarette 100 further includes a switch assembly 140 for opening or closing the through hole 121. The switch assembly 140 includes a driving key 141 and a movable part 142 connected to the driving key 141, and the driving key 141 is configured to drive the movable part 142 to move between a first position and a second position. Figure 2 As shown, at the first position, the movable part 142 covers the through hole 121 to close the through hole 121. Figure 4 As shown, at the second position, the movable component 142 is at least partially offset from the through hole 121 to open the through hole 121 .

[0062] According to some embodiments of the present disclosure, an opening 131 is provided on the wall of the second oil storage tank 130, a driving key 141 is at least partially embedded in the opening 131, and a movable component 142 connected to the driving key 141 is provided between the wall of the first oil storage tank 120 and the wall of the second oil storage tank 130. The driving key 141 may partially protrude from the opening 131 for easy operation by a user.

[0063] According to some embodiments of the present disclosure, the electronic cigarette 100 further includes a component 160 containing a flavor regulator. The component 160 containing a flavor regulator is arranged around the atomizer core 110 and is located above the heating element of the atomizer core. The outer tube wall of the atomizer core 110 is provided with a plurality of windows 111, so that the smoke formed by heating by the heating element can flow through the plurality of windows 111 through the component 160 containing a flavor regulator.

[0064] See also Figure 2 A portion of the window 111 leads to the oil storage cotton 124 in the first oil storage bin 120, so that the tobacco oil stored in the oil storage cotton 124 can pass through the window 111 into the interior of the atomizer core, and be heated by the heating element 113 to form smoke. Another portion of the window 111 leads to the component 160 containing the flavor regulator, so that the smoke formed by the heating element 113 can pass through the window 111 and flow through the component 160 containing the flavor regulator, and bring the flavor contained in the component 160 containing the flavor regulator to the mouthpiece for inhalation by the user. The component 160 containing the flavor regulator is, for example, a capsule containing the flavor regulator. Figure 2 As shown, its shape can be circular. The taste modifier is, for example, a flavor modifier, which is used to provide various flavors to the user, and is, for example, nicotine, etc., so as to provide a stronger smell experience for the user to inhale.

[0065] See also Figure 2 The wall of the first oil storage tank 121 is bulged inward at a position corresponding to the window 111 on the outer tube wall of the atomizer core to form a second step portion 125. The component 160 containing the flavor regulator can be placed on the second step portion 125.

[0066] According to some embodiments of the present disclosure, the electronic cigarette includes an airflow sensor 170 , and a first air inlet passage through the airflow sensor 170 and a second air inlet passage through the atomizer core are separated from each other.

[0067] Existing electronic cigarettes usually have only one air inlet channel, that is, air is taken in from the air inlet, and then the airflow passes through the atomizer core, carrying the smoke generated by heating the smoke oil and being discharged from the exhaust channel in the atomizer tube of the atomizer core to the mouthpiece. Usually, the airflow sensor is arranged at the air inlet of the air inlet channel. When the user inhales, the airflow passes through the airflow sensor, which triggers the heating element to heat. According to some embodiments of the present disclosure, in addition to the first air inlet channel passing through the atomizer core, a second air inlet channel is also provided, and the second air inlet channel is separated from the first air inlet channel. The airflow sensor 170 is located in the second air inlet channel, that is, the airflow sensor 170 is arranged in the second air inlet channel independent of the first air inlet channel. In this way, when the exhaust channel is blocked by the smoke condensate, the other air inlet channel, that is, the second channel, can still remain unobstructed, and the user can still activate the airflow sensor and start heating when inhaling. After heating, the condensate blocking the exhaust channel will also be heated again, so that the exhaust channel is unobstructed again.

[0068] The airflow sensor 130 is, for example, disposed in a position close to the upper end of the electronic cigarette along the direction of the second airflow channel. Figure 2 The airflow sensor 130 is disposed above the power supply assembly 150 and is laterally spaced from the atomizer core 110 .

[0069] The first air inlet passage and the second air inlet passage, for example Figure 2 As shown, a common air inlet 151 can be used. In other examples, a first air inlet for the first air inlet passage and a second air inlet for the second air inlet passage can be designed separately, so that the first air inlet passage and the second air inlet passage are completely separated.

[0070] According to some embodiments of the present disclosure, the electronic cigarette 100 further includes an oil-absorbing cotton 180, which is disposed below the mouthpiece 190 of the electronic cigarette 100. Figure 2 An oil-absorbing cotton 180 is provided between the top of the atomizing tube 112 and the cigarette holder 190, and a second through hole 181 is provided in the middle of the oil-absorbing cotton 180, which is connected to the smoke exhaust passage in the atomizing tube 112. The oil-absorbing cotton 180 can absorb the condensed smoke liquid generated in the smoke exhaust passage and the cigarette holder to prevent oil leakage.

[0071] According to some embodiments of the present disclosure, the electronic cigarette 100 further includes a power supply assembly 150 for supplying power to the atomizer core. The power supply assembly 150 may be a rechargeable battery assembly. Figure 2 The power supply assembly 150 is arranged side by side with the first oil storage bin 120 and is surrounded by the second oil storage bin 130. The power supply assembly 150 is sealed and separated from the first oil storage bin 120 and the second oil storage bin 130 to prevent the oil from leaking into the power supply assembly 150, which would cause the power supply assembly 150 to malfunction.

[0072] Figure 5 shows an exploded view of an electronic cigarette according to some embodiments of the present disclosure, Figure 5 FIG. 2 shows an exploded view of some components of the atomizer core according to some embodiments of the present disclosure. Figure 5 As shown, the shell of the electronic cigarette 100 mainly includes an outer shell 101, an inner shell 102 and a bottom shell 103. The inner shell 102 is placed inside the outer shell 101, and the bottom shell 103 closes the bottom of the outer shell 101 and the inner shell 102. The atomization core 110 of the electronic cigarette includes an atomization tube 112, a heating element 113, oil-conducting cotton 114 and a metal stopper 115. The heating element 113 is wrapped by the oil-conducting cotton 114 and is retained in the atomization tube 112 by the metal stopper 115. The atomization core 110 is surrounded by oil-storage cotton 124, and a hole is provided in the oil-storage cotton 124, and the atomization core 110 is placed in the hole. The atomizer core 110 wrapped with the oil storage cotton 124 and the battery assembly 150 are respectively placed in the first cavity 1021 and the second cavity 1022 in the inner shell 102, and the first cavity 1021 and the second cavity 1022 are separated from each other by the longitudinal wall 1023 in the inner shell 102 to prevent the tobacco oil in the first cavity 1021 from entering the battery assembly 150. The first cavity 1021 serves as the first oil storage bin 120. The second oil storage bin 130 is formed between the inner side of the outer shell 101 and the outer side of the inner shell 102.

[0073] The base 126 is arranged in the bottom shell 103. The lower silicone member 127 is located between the base 126 and the lower end of the inner shell 102, and the upper silicone member 128 is located at the upper end of the inner shell 102, so as to seal the battery assembly 150 located in the inner shell 102, and prevent the oil in the first oil storage bin 120 in the inner shell 102 from leaking, and prevent the oil in the first oil storage bin 120 from leaking laterally into the second cavity 1022 of the inner shell 102, thereby damaging the battery assembly 150.

[0074] The opening 131 is provided on the bottom shell 103 , the switch assembly 140 is partially embedded in the opening 131 and is located between the outer side of the inner shell 102 and the inner side of the bottom shell 103 , and the driving key 141 of the switch assembly 140 can be partially exposed through the opening 131 , which is convenient for user operation.
