Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an electronic cigarette. Background Technology

[0002] High-capacity e-cigarettes typically include a refill chamber, which stores e-liquid and supplies it to a foam cartridge within the refill chamber. The atomizing component draws e-liquid from the foam cartridge and, powered by a power supply, atomizes the e-liquid. The atomized vapor then flows out through the mouthpiece, which connects to the atomizing chamber, for the user to inhale.

[0003] However, it is difficult to precisely control the amount of e-liquid injected into the e-liquid reservoir. When there is too much e-liquid on the reservoir, the atomizer is soaked in too much e-liquid, which can easily lead to leakage and insufficient atomization. When there is too little e-liquid on the reservoir, the atomizer cannot absorb enough e-liquid, which can easily cause dry burning. Utility Model Content

[0004] The main purpose of this application is to provide an electronic cigarette that solves the technical problem of accurately controlling the amount of oil injected into the oil storage cotton from the oil supply tank.

[0005] To achieve the above objectives, this application proposes an electronic cigarette, the electronic cigarette comprising:

[0006] The housing has an installation port;

[0007] An oil storage tank is located inside the housing and is sealed to the housing. The oil storage tank has an oil filling port corresponding to the installation port.

[0008] An atomizing component is disposed in the oil storage tank, and an oil inlet is provided on the atomizing component;

[0009] An oil-storing cotton is placed inside the oil storage chamber and is fitted over the atomizing component. The outer wall of the oil-storing cotton is recessed inward to form a channel. The top of the channel is flush with the top of the oil-storing cotton, and the bottom of the channel is lower than the top of the oil inlet.

[0010] A guide tube, passing through the mounting port and the oil inlet, one end of the guide tube extending into the channel, and the bottom end of the guide tube being lower than the top end of the oil inlet hole; and

[0011] An oil supply chamber, at least partially located outside the housing, is connected at one end to the end of the guide tube away from the oil storage cotton, and the oil supply chamber is connected to the guide tube.

[0012] Optionally, the oil supply tank includes a tank body and an oil supply end connected to each other, the oil supply end being at least partially located below the tank body, and the end of the oil supply end away from the tank body being detachably connected to the guide cylinder.

[0013] Optionally, the oil supply end is interference-fitted with the guide cylinder.

[0014] Optionally, the guide tube includes a first sub-tube and a second sub-tube connected to each other, the diameter of the first sub-tube being smaller than the diameter of the second sub-tube, the first sub-tube abutting against the oil storage cotton, and the second sub-tube being connected to the oil supply chamber.

[0015] Optionally, the end of the first sub-tube away from the oil storage cotton is fitted inside the second sub-tube, and the end of the first sub-tube fitted inside the second sub-tube is used to puncture the oil supply chamber.

[0016] Optionally, the electronic cigarette further includes a sealing ring disposed between the guide tube and the oil supply chamber, the sealing ring being used to seal the guide tube and the oil supply chamber.

[0017] Optionally, the number of the installation port, the oil inlet, the guide cylinder, and the oil supply chamber are all two, and the two oil supply chambers are arranged in a one-to-one correspondence with the two guide cylinders.

[0018] Optionally, there are two of each of the mounting port, the oil inlet, and the guide cylinder. The oil supply chamber is tubular, flexible, or arc-shaped. The two ends of the oil supply chamber are respectively connected to the two guide cylinders.

[0019] Optionally, the length of the oil supply chamber is greater than or equal to 10cm and less than or equal to 100cm; the inner diameter of the oil supply chamber is greater than or equal to 1.5mm and less than or equal to 10mm.

[0020] Optionally, the two mounting ports are located on opposite sides of the housing.

[0021] Optionally, the extension direction of the channel is parallel to the extension direction of the oil-storing cotton.

[0022] Optionally, the bottom end of the channel is flush with the bottom end of the oil-storing cotton.

[0023] In the electronic cigarette of this application, by setting a guide tube and a channel on the oil storage cotton, one end of the guide tube extends into the channel and the bottom end is lower than the top end of the oil inlet. The top end of the channel is flush with the top end of the oil storage cotton, and the bottom end of the channel is lower than the top end of the oil inlet. This allows the oil supply chamber to inject oil into the oil storage chamber while the oil storage chamber returns air to the oil supply chamber. As a result, the oil injection process can be automatically adjusted, and the e-liquid content on the oil storage cotton is relatively stable.

[0024] Specifically, as the e-liquid in the supply chamber flows into the storage chamber through the conduit, the gas in the storage chamber flows into the supply chamber through the channel and conduit. This pressure balance between the supply and storage chambers allows the e-liquid in the supply chamber to flow relatively quickly and continuously into the reservoir. When the reservoir is sufficiently wetted, the surface tension of the e-liquid creates a liquid seal in the channel, preventing air from entering. This balances the weight of the e-liquid, the capillary force of the reservoir, and the pressure in the supply chamber, preventing further e-liquid from flowing into the reservoir. This avoids leakage when the atomizer is not in operation. When a user inhales, the e-liquid in the atomizer is consumed. The atomizer draws e-liquid from the reservoir, causing the e-liquid saturation in the reservoir to decrease. This breaks the liquid blockage formed by the channels, allowing air to return to the interior of the e-liquid chamber. The e-liquid in the e-liquid chamber then begins to flow back into the reservoir. As a result, the reservoir can always remain relatively moist (when there is e-liquid in the e-liquid chamber), ensuring a stable e-liquid supply to the atomizer and preventing the atomizer from burning dry.

[0025] In summary, the electronic cigarette of this application can automatically regulate the supply of e-liquid, and the e-liquid content on the oil reservoir is stable, thereby ensuring consistent atomization, preventing leakage, and avoiding dry burning of the atomization components.

[0038] This application discloses an electronic cigarette, comprising a shell, an oil reservoir, an atomizing component, an oil-retaining cotton, a conduit tube, and an oil supply chamber; the shell has an installation port; the oil reservoir is located inside the shell and is sealed to the shell, and the oil reservoir has an oil filling port corresponding to the installation port; the atomizing component is located inside the oil reservoir and has an oil inlet hole; the oil-retaining cotton is located inside the oil reservoir and is sleeved outside the atomizing component, the outer wall of the oil-retaining cotton is recessed inward to form a channel, the top of the channel is flush with the top of the oil-retaining cotton, and the bottom of the channel is lower than the top of the oil inlet hole; the conduit tube passes through the installation port and the oil filling port, one end of the conduit tube extends into the channel, and the bottom of the conduit tube is lower than the top of the oil inlet hole; the oil supply chamber is at least partially located outside the shell, one end of the oil supply chamber is connected to the end of the conduit tube away from the oil-retaining cotton, and the oil supply chamber is connected to the conduit tube.

[0039] In the electronic cigarette of this application, by setting a guide tube and a channel on the oil storage cotton, one end of the guide tube extends into the channel and the bottom end is lower than the top end of the oil inlet. The top end of the channel is flush with the top end of the oil storage cotton, and the bottom end of the channel is lower than the top end of the oil inlet. This allows the oil supply chamber to fill the oil storage chamber while the oil storage chamber returns air to the oil supply chamber. As a result, the electronic cigarette of this application can automatically adjust the supply of e-liquid, thereby ensuring the consistency of atomization, preventing leakage, and avoiding dry burning of the atomization component.

[0040] The following will mainly describe the specific structure of electronic cigarettes.

[0041] Please see Figures 1 to 4 The electronic cigarette 100 of this application includes a housing 110. The housing 110 can be cylindrical in shape, and its cross-section can be circular, elliptical, racetrack-shaped, polygonal, or irregular in shape. The housing 110 can be made of materials such as resin, plastic, or glass. An installation opening 111 is provided on the housing 110. The installation opening 111 can be circular, elliptical, racetrack-shaped, polygonal, or irregular in shape. The number of installation openings 111 can be one or more.

[0042] Please see Figure 2 and Figure 3 The electronic cigarette 100 of this application includes an oil reservoir 120. The oil reservoir 120 is capable of storing e-liquid. The oil reservoir 120 can be cylindrical in shape, and its cross-section can be circular, elliptical, racetrack-shaped, polygonal, or irregularly shaped. The oil reservoir 120 is disposed within a housing 110, and the oil reservoir 120 is sealed to the housing 110. The oil reservoir 120 and the housing 110 can be connected by snap-fit, adhesive, or screw. The oil reservoir 120 has an oil filling port 121 corresponding to the mounting port 111. The oil filling port 121 can also be circular, elliptical, racetrack-shaped, polygonal, or irregularly shaped. The number of oil filling ports 121 is equal to the number of mounting ports 111, or there can be one or more.

[0043] Please see Figure 2 and Figure 3 The electronic cigarette 100 of this application includes an atomizing component 130, which is disposed within an oil reservoir 120. The atomizing component 130 has an oil inlet 131. When powered, the atomizing component 130 atomizes e-liquid into an aerosol, which flows into the atomizing component 130 through the oil inlet 131. The shape of the oil inlet 131 can be circular, elliptical, racetrack-shaped, polygonal, or irregular. There can be multiple oil inlets 131, which can be arranged circumferentially along the atomizing component 130.

[0044] Please see Figure 2 and Figure 3The electronic cigarette 100 of this application includes an oil-collecting cotton 140. The oil-collecting cotton 140 is disposed inside the oil storage chamber 120 and is sleeved on the outside of the atomizing component 130. The oil-collecting cotton 140 can absorb the e-liquid flowing into the oil storage chamber 120 and transfer the e-liquid to the atomizing component 130 through the oil inlet 131.

[0045] Please see Figure 2 and Figure 3 The outer wall of the oil-retaining cotton 140 is recessed inward to form a channel 141. The top of the channel 141 is flush with the top of the oil-retaining cotton 140, and the bottom of the channel 141 is lower than the top of the oil inlet 131. The channel 141 can guide the flow of e-liquid and gas. Understandably, e-liquid is denser than air, and due to its surface tension, it will adhere to the lower half of the oil guide tube and flow. The upper half of the oil guide tube is a cavity, and air flows in the cavity of the oil guide tube, thereby realizing the filling and air return of the oil supply chamber 160 and the oil storage chamber 120.

[0046] Please see Figure 2 and Figure 3 The extension direction of channel 141 is parallel to the extension direction of oil storage cotton 140. Therefore, the extension direction of channel 141 is the same as the direction of gravity, resulting in better oil and gas guiding effects of channel 141.

[0047] Please see Figure 2 and Figure 3 The bottom end of channel 141 is flush with the bottom end of the e-liquid reservoir 140. When the e-liquid reservoir 140 is moistened to a certain extent, under the action of the surface tension of the e-liquid, channel 141 forms a liquid seal to prevent air from entering. This balances the weight of the e-liquid, the capillary force of the e-liquid reservoir 140, and the pressure inside the e-liquid chamber 160, preventing the e-liquid in the e-liquid chamber 160 from flowing back to the e-liquid reservoir 140. Therefore, leakage is avoided when the atomizing component 130 is not operating. This design ensures a good liquid seal effect in channel 141.

[0048] Please see Figure 2 and Figure 3 The electronic cigarette 100 of this application includes a guide tube 150. The guide tube 150 passes through the mounting port 111 and the oil filling port 121, with one end of the guide tube 150 extending into the channel 141, and the bottom end of the guide tube 150 being lower than the top end of the oil inlet 131. The guide tube 150 can guide external e-liquid to flow into the channel 141 and guide the gas in the channel 141 to flow out to the outside.

[0049] Please see Figure 2 and Figure 3The oil storage tank 120 has a recessed mounting groove 122 corresponding to the guide tube 150. The bottom of the mounting groove 122 is connected to the oil filling port 121. The guide tube 150 is installed in the mounting groove 122, which can improve the connection effect between the oil storage tank 120 and the guide tube 150, and also make the overall structure of the electronic cigarette 100 more compact.

[0050] Please see Figures 1 to 4 The electronic cigarette 100 of this application includes an e-liquid supply chamber 160. The e-liquid supply chamber 160 is used to supply e-liquid to the e-liquid reservoir 140. The e-liquid supply chamber 160 is at least partially located outside the housing 110, and one end of the e-liquid supply chamber 160 is connected to the end of the conduit 150 away from the e-liquid reservoir 140, thus communicating with the conduit 150. Therefore, the e-liquid supply chamber 160 can supply e-liquid to the e-liquid reservoir 120.

[0051] In the electronic cigarette 100 of this application, by setting a guide tube 150 and a channel 141 on the oil storage cotton 140, one end of the guide tube 150 extends into the channel 141 and the bottom end is lower than the top end of the oil inlet hole 131. The top end of the channel 141 is flush with the top end of the oil storage cotton 140, and the bottom end of the channel 141 is lower than the top end of the oil inlet hole 131. At the same time as the oil supply chamber 160 injects oil into the oil storage chamber 120, the oil storage chamber 120 can return air to the oil supply chamber 160. Thus, the oil injection process can be automatically adjusted, and the e-liquid content on the oil storage cotton 140 is relatively stable.

[0052] Please see Figure 2 and Figure 3 The oil supply chamber 160 includes a chamber body 161 and an oil supply end 162 connected to each other. The oil supply end 162 is at least partially located below the chamber body 161, and the end of the oil supply end 162 away from the chamber body 161 is detachably connected to the guide tube 150. Therefore, when the electronic cigarette 100 is upright, the oil supply chamber 160 can supply oil to the oil storage chamber 120, and the installation and replacement of the oil supply chamber 160 are relatively convenient. The chamber body 161 and the oil supply end 162 can be integrally formed. Alternatively, the chamber body 161 and the oil supply end 162 can be detachably connected, for example, by snap-fit, adhesive, or screw connection. The oil supply end 162 and the guide tube 150 can be snap-fit, adhesive, or screw connection.

[0053] The oil supply end 162 and the guide cylinder 150 can be interference-fitted. The oil supply end 162 and the guide cylinder 150 can both be made of rigid material; or one can be made of rigid material and the other of elastic material; or both can be made of elastic material.

[0054] Please see Figure 2 and Figure 3The guide tube 150 includes a first sub-tube 151 and a second sub-tube 152 connected to each other. The diameter of the first sub-tube 151 is smaller than the diameter of the second sub-tube 152. The first sub-tube 151 abuts against the oil storage cotton 140, and the second sub-tube 152 is connected to the oil supply chamber 160. Specifically, the second sub-tube 152 is connected to the oil supply end 162. The above arrangement makes the connection between the oil supply chamber 160, the guide tube 150, the housing 110, and the oil storage chamber 120 relatively tight, and it is not easy for oil leakage to occur.

[0055] Please see Figure 2 and Figure 3 The end of the first sub-tube 151 furthest from the oil-retaining cotton 140 is fitted inside the second sub-tube 152. The end of the first sub-tube 151 fitted inside the second sub-tube 152 is used to puncture the oil supply chamber 160. Therefore, when assembling the oil supply chamber 160 and the oil storage chamber 120, it is not necessary to open the oil supply port of the oil supply chamber 160 in advance. When the oil supply chamber 160 and the oil storage chamber 120 are assembled, the flow of e-liquid can be achieved, making the assembly of the oil supply chamber 160 and the oil storage chamber 120 relatively convenient.

[0056] Please see Figure 2 and Figure 3 The electronic cigarette 100 of this application also includes a sealing ring 170, which is disposed between the guide tube 150 and the e-liquid reservoir 160. The sealing ring 170 is used to seal the guide tube 150 and the e-liquid reservoir 160. Therefore, the electronic cigarette 100 is less prone to leakage. The sealing ring 170 can be made of an elastic material and can be interference-fitted between the guide tube 150 and the e-liquid reservoir 160, thereby achieving a better sealing effect.

[0057] Please see Figures 1 to 3 In one embodiment, there are two of each of the mounting port 111, the e-liquid inlet 121, the conduit tube 150, and the e-liquid supply chamber 160, with the two e-liquid supply chambers 160 corresponding one-to-one with the two conduit tubes 150. This allows for the supply of a relatively large amount of e-liquid and also enables the supply of e-liquids with different flavors.

[0058] Please see Figure 4 In another embodiment, there are two mounting ports 111, two oil filling ports 121, and two guide tubes 150. The oil supply chamber 160 is tubular, flexible, or arc-shaped, and its two ends are connected to two guide tubes 150 respectively. Based on the above configuration, the oil supply chamber 160 can be carried by hand or hung around the neck, thus expanding the usage scenarios of the electronic cigarette 100.

[0059] In the above embodiment, the length of the oil supply tank 160 is greater than or equal to 10 cm and less than or equal to 100 cm; the inner diameter of the oil supply tank 160 is greater than or equal to 1.5 mm and less than or equal to 10 mm. By adjusting the length and inner diameter of the oil supply tank 160, the oil storage capacity of the oil supply tank 160 can be adjusted.

[0060] Please see Figures 1 to 4 Two mounting ports 111 are located on opposite sides of the housing 110. As a result, when the e-cigarette 100's oil supply chamber 160 is installed, the overall center of gravity of the e-cigarette 100 is close to the middle, making it less likely to tip over unintentionally, and the e-cigarette 100 is also more aesthetically pleasing.

[0061] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
