Description

Technical Field

[0001] This utility model relates to the field of atomization technology, and in particular to a cigarette cartridge and an electronic atomization device. Background Technology

[0002] In recent years, with the rapid development of electronic atomization technology, e-liquid cartridges, as the core functional component of electronic atomizers, directly affect the user experience through their structural design and performance. Currently, most mainstream e-liquid cartridges on the market adopt a support-type structure design, mainly composed of a support, heating coil, and e-liquid reservoir. During operation, the heating coil generates high temperatures when energized, causing the e-liquid adsorbed in the reservoir to atomize and form an aerosol that can be inhaled by the user.

[0003] However, existing e-liquid cartridge designs have significant technical flaws: the e-liquid reservoir inside the holder frequently leaks. Specifically, this manifests in two ways: firstly, e-liquid may seep downwards into the device's circuit board area, causing short circuits or component corrosion, severely impacting the device's lifespan and safety; secondly, e-liquid may also seep upwards into the mouthpiece, not only causing abnormal taste, such as an overly strong or bitter flavor, but also potentially leading to direct contact with unchemified e-liquid, posing a health risk.

[0004] Therefore, improvements to existing technologies are necessary. Summary of the Invention

[0005] This application provides a tobacco cartridge and an electronic atomizing device, aiming to improve the problem of frequent leakage of oil-retaining cotton inside the tobacco cartridge holder, which leads to short circuits or component corrosion, seriously affecting the service life and safety of the device and the taste.

[0006] Therefore, this application provides a cigarette cartridge, including a bracket and an oil-proof and breathable membrane. The bracket is provided with a heating wire and an oil-storing cotton for storing e-liquid. When the heating wire is working, it can atomize the e-liquid stored in the oil-storing cotton to form an aerosol.

[0007] Both ends of the bracket have openings, and the oil-proof and breathable membranes are respectively provided on both sides of the oil-storing cotton. The oil-proof and breathable membranes are used to seal the openings at both ends of the bracket to prevent oil leakage while allowing gas to pass through.

[0008] Furthermore, the e-cigarette cartridge also includes a cartridge shell and a bottom cover. The cartridge shell has a mist outlet channel and an oil storage chamber surrounding the mist outlet channel. The bottom cover is detachably connected to the bottom opening of the cartridge shell to seal the oil storage chamber. The bottom cover has an air intake channel. One end of the bracket is connected to the mist outlet channel, and the other end of the bracket is located inside the bottom cover and connected to the air intake channel. The peripheral wall of the bracket has several oil inlet holes, through which the e-liquid in the oil storage chamber reaches the oil storage cotton.

[0009] Furthermore, the inner diameter of the bracket is larger than the outer diameter of the mist outlet channel, the mist outlet channel is located within the upper end of the bracket, and sealing silicone parts are provided at both ends of the bracket, with the oil-proof and breathable membrane provided within the sealing silicone parts.

[0010] Furthermore, the sealing silicone part is provided with a limiting groove, and the oil-proof and breathable membrane is disposed in the limiting groove.

[0011] Furthermore, the mist outlet channel includes an upper channel and a lower channel that are connected. The inner diameter of the lower channel is larger than the inner diameter of the upper channel. The outer diameter of the bracket is smaller than the inner diameter of the lower channel of the mist outlet channel. The upper end of the bracket is confined within the lower channel.

[0012] Furthermore, a sealing silicone element is provided in both the upper and lower ends of the bracket, and the sealing silicone element is provided with the limiting groove, and the oil-proof and breathable membrane is disposed in the limiting groove.

[0013] Furthermore, the upper end of the bracket is provided with an oil-proof and breathable membrane, which is located at the connection between the upper channel and the lower channel. The top surface of the upper end of the bracket abuts against the oil-proof and breathable membrane. The lower end of the bracket is provided with a sealing silicone component, which contains the oil-proof and breathable membrane.

[0014] Furthermore, the bottom cover is provided with an oil injection hole, which is connected to the oil storage cavity, and a sealing plug is provided in the oil injection hole.

[0015] Furthermore, the bottom cover has buckles on both sides, and the bottom of the cartridge shell has a corresponding slot, with the buckles and slots engaging.

[0016] Additionally, an electronic atomizing device includes the aforementioned cigarette cartridge.

[0017] This application provides a tobacco cartridge and electronic atomizing device. The tobacco cartridge includes a support and an oil-proof and breathable membrane. The support contains a heating wire and an oil-storing cotton for storing e-liquid. When the heating wire is working, it atomizes the e-liquid stored in the oil-storing cotton to form an aerosol. Both ends of the support have openings, and oil-proof and breathable membranes are respectively provided on both sides of the oil-storing cotton. These membranes effectively seal the openings at both ends of the support. The bottom oil-proof and breathable membrane prevents e-liquid from leaking downwards and seeping into the circuit board, reducing the risk of short circuits and component corrosion, and improving the lifespan and safety of the device. The top oil-proof membrane prevents e-liquid from leaking upwards to the mouthpiece, ensuring that users will not experience abnormal taste problems due to e-liquid seepage when using the tobacco cartridge. It also prevents users from directly contacting un-atomized e-liquid, protecting the user's health. Attached Figure Description

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] In one embodiment, such as Figures 1 to 6 As shown in the illustration, this application provides a tobacco cartridge, comprising: a cartridge shell 1, which is cylindrical in shape with an opening at the bottom; a mist outlet channel 2 located at the center of the cartridge shell 1 and connected to a mouthpiece; and a vapor-like aerosol particles generated by the atomized e-liquid being discharged through the mist outlet channel 2. An oil storage chamber 3 is provided around the mist outlet channel 2 for storing e-liquid. A bottom cover 4 is detachably connected to the bottom opening of the cartridge shell 1 to seal the oil storage chamber 3. The bottom cover 4 also provides an air intake channel 40; when the user inhales, external air enters the cartridge shell 1 through the air intake channel 40. The bracket 5 has openings at both ends. One end of the bracket 5 is connected to the mist outlet channel 2, and the other end of the bracket 5 is located inside the bottom cover 4 and connected to the air inlet channel 40. The bracket 5 is equipped with an atomizing core assembly, which includes an oil storage cotton 6 and a heating wire 7.

[0033] In a specific embodiment, the upper and lower ports of the bracket 5 are connected to the vapor outlet channel 2 and the air inlet channel 40, respectively. An oil inlet hole 50 is provided on the peripheral wall of the bracket 5. The e-liquid in the oil storage chamber 3 enters the oil storage cotton 6 through the oil inlet hole 50. Through the user's inhalation action, external air enters the cavity of the electronic atomizing device and enters the atomizing core assembly inside the bracket 5 through the air inlet channel 40. The microphone inside the e-liquid device controls the heating wire 7 to start and stop. When inhaling, the microphone senses the inhalation signal and controls the heating wire 7 to start, atomizing the e-liquid in the oil storage cotton 6. When inhaling stops, the microphone controls the heating wire 7 to stop.

[0034] In addition, oil-proof and breathable membranes 100 are provided at both ends of the bracket 5. The oil-proof and breathable membranes 100 are located on the upper and lower sides of the oil-collecting cotton 6 and are spaced apart from the oil-collecting cotton 6. It can be understood that the oil-proof and breathable membranes 100 have good air permeability, which can ensure that air can smoothly enter the air intake channel 40. At the same time, the oil-proof and breathable membranes 100 also have an oil-proof function, which can effectively prevent e-liquid from entering the air intake channel 40 and reaching the circuit board, thus contaminating the circuit board. It can also prevent e-liquid from entering the mist outlet channel 2 and thus affecting the taste.

[0035] Working principle: Oil-proof and breathable membranes 100 are set above and below the oil-storage cotton 6 in the bracket 5. The oil-proof and breathable membranes 100 have good air permeability, which can ensure that air can smoothly enter the air intake channel 40 and the mist outlet channel 2. At the same time, the oil-proof and breathable membranes 100 also have an oil-proof function, which can effectively prevent e-liquid from entering the air intake channel 40 and reaching the circuit board, and can also prevent e-liquid from entering the mist outlet channel 2 and affecting the user's taste.

[0036] In yet another specific embodiment, such as Figures 1-2 As shown, the inner diameter of the bracket 5 is set to be larger than the outer diameter of the mist outlet channel 2, and the mist outlet channel 2 is located within the upper end of the bracket 5; both ends of the bracket 5 are provided with sealing silicone parts 8, which are located on the upper and lower sides of the oil storage cotton 6. The sealing silicone part 8 located above the oil storage cotton 6 is positioned below the mist outlet channel 2. The oil-proof and breathable membrane 100 is provided inside the sealing silicone part 8, so that the aerosol particles of the e-liquid after being atomized pass through the oil-proof and breathable membrane 100 before entering the mist outlet channel 2, thus isolating the e-liquid and improving the user's taste.

[0037] Optionally, the sealing silicone component 8 is provided with a limiting groove 80, and the oil-proof and breathable membrane 100 is disposed within the limiting groove 80. Specifically, in order to fix the oil-proof and breathable membrane 100 within the sealing silicone component 8, a limiting groove 80 is provided within the sealing silicone component 8, and the oil-proof and breathable membrane 100 is disposed within the limiting groove 80.

[0038] Optionally, the bracket 5 is provided with an oil inlet 50, the position of which corresponds to the position of the oil storage cotton 6 and is located above the bottom cover 4. It can be understood that by providing the oil inlet 50 on the bracket 5, and with the oil inlet 50 located above the bottom cover 4, the e-liquid in the oil storage chamber 3 can enter the oil storage cotton 6, ensuring that the oil storage cotton 6 has sufficient e-liquid.

[0039] Optionally, the bottom cover 4 is provided with an oil injection hole 41, which is connected to the oil storage cavity 3, and a sealing plug 42 is provided in the oil injection hole 41.

[0040] Specifically, an oil filling hole 41 is provided inside the bottom cover 4. The oil filling hole 41 is connected to the oil storage chamber 3. Oil is filled through the oil filling hole 41 and sealed by the sealing plug 42. When the e-liquid in the oil storage chamber 3 is used up, the sealing plug 42 is removed and oil is filled. The e-liquid is injected into the channel of the oil storage chamber 3 from the outside. After the oil is filled, the sealing plug 42 seals the oil filling hole 41.

[0041] In addition, the bottom cover 4 has buckles 43 on both sides, and the bottom of the cartridge shell 1 has a corresponding slot 10, and the buckles 43 and the slot 10 are engaged.

[0042] Specifically, the bottom cover 4 is provided with a buckle 43, and the cartridge shell 1 is provided with a slot 10. The buckle 43 engages with the slot 10. The design of the buckle 43 and the slot 10 makes the bottom cover 4 easy to disassemble and install, which facilitates the user to replace easily damaged parts (such as oil storage cotton 6 and heating wire 7), avoids frequent replacement of the entire cartridge, and reduces the cost of use.

[0043] Furthermore, the bottom of the bottom cover 4 is also provided with a number of electrode nails 44, one end of which is connected to the heating wire 7, and the other end of which is electrically connected to the power supply component inside the cigarette rod (not shown in the figure).

[0044] In yet another specific embodiment, such as Figures 3-4 As shown, the outer diameter of the bracket 5 is smaller than the inner diameter of the mist outlet channel 2. Specifically, the mist outlet channel 2 includes an upper channel 201 and a lower channel 202 that are connected. The inner diameter of the lower channel 202 is larger than the inner diameter of the upper channel 201. The outer diameter of the bracket 5 is smaller than the inner diameter of the lower channel 202 of the mist outlet channel 2. The upper end of the bracket 5 is located within the lower channel 202.

[0045] Specifically, the upper end of the bracket 5 is embedded in the mist outlet channel 2, and the top surface of the upper end of the bracket 5 rests on the lower opening of the upper channel 201. Since the inner diameter of the upper channel 201 is smaller than the inner diameter of the lower channel 202, the connection between the upper channel 201 and the lower channel 202 forms an inwardly protruding accommodating space on both sides.

[0046] In this specific embodiment, a sealing silicone element 8 is provided in both the upper and lower ends of the bracket 5, and a limiting groove 80 is provided in the sealing silicone element 8. The oil-proof and breathable membrane 100 is disposed in the limiting groove 80.

[0047] like Figure 5 As shown, in another specific design, the outer diameter of the bracket 5 is smaller than the inner diameter of the mist outlet channel 2. Specifically, the mist outlet channel 2 includes a connected upper channel 201 and a lower channel 202. The inner diameter of the lower channel 202 is larger than the inner diameter of the upper channel 201. The outer diameter of the bracket 5 is smaller than the inner diameter of the lower channel 202 of the mist outlet channel 2. The upper end of the bracket 5 is confined within the lower channel 202. The upper end of the bracket 5 is embedded in the mist outlet channel 2, with the top surface of the upper end of the bracket 5 abutting the lower opening of the upper channel 201. Since the inner diameter of the upper channel 201 is smaller than the inner diameter of the lower channel 202, the connection between the upper channel 201 and the lower channel 202 forms an inwardly protruding accommodating space on both sides.

[0048] Specifically, instead of a sealing silicone piece 8, an oil-proof and breathable membrane 100 is directly provided in the upper end of the bracket 5. The oil-proof and breathable membrane 100 is located in the accommodating space formed at the connection between the upper channel 201 and the lower channel 202. The top surface of the upper end of the bracket 5 abuts against the oil-proof and breathable membrane 100, and the two inward protrusions on both sides of the connection abut against the upper and lower surfaces of the oil-proof and breathable membrane 100 to fix the oil-proof and breathable membrane 100.

[0049] In this embodiment, a sealing silicone element 8 is provided in the lower end of the bracket 5, and a limiting groove 80 is provided in the sealing silicone element 8. The oil-proof and breathable membrane 100 is disposed in the limiting groove 80.

[0050] In addition, the bottom cover 4 has buckles 43 on both sides, and the bottom of the cartridge shell 1 has a corresponding slot 10, and the buckles 43 and the slot 10 are engaged.

[0051] Furthermore, the bottom cover 4 is provided with an oil injection hole 41, which is connected to the oil storage cavity 3, and a sealing plug 42 is provided in the oil injection hole 41.

[0052] The bottom cover 4 has buckles 43 on both sides, and the bottom of the cartridge shell 1 has a corresponding slot 10, and the buckles 43 and the slot 10 are engaged.

[0053] Specifically, the bottom cover 4 is provided with a buckle 43, and the cartridge shell 1 is provided with a slot 10. The buckle 43 engages with the slot 10. The design of the buckle 43 and the slot 10 makes the bottom cover 4 easy to disassemble and install, which facilitates the user to replace easily damaged parts (such as oil storage cotton 6 and heating wire 7), avoids frequent replacement of the entire cartridge, and reduces the cost of use.

[0054] Furthermore, the bottom of the bottom cover 4 is also provided with a number of electrode nails 44, one end of which is connected to the heating wire 7, and the other end of which is electrically connected to the power supply component inside the cigarette rod (not shown in the figure).

[0055] In addition, in a specific embodiment, an electronic atomizing device is provided, including the aforementioned e-cigarette cartridge. The electronic atomizing device also includes a vaporizer, which contains a microphone, a circuit board, and a battery assembly. The microphone controls the heating wire 7 to start and stop. When inhaling, the microphone senses a suction signal and controls the heating wire 7 to start, atomizing the e-liquid in the oil reservoir 6. When inhalation stops, the microphone controls the heating wire 7 to stop.

[0056] In summary, through the above structural design, oil-proof and breathable membranes are installed above and below the oil-collecting cotton inside the bracket. These membranes have excellent breathability, ensuring that air can smoothly enter the air intake and mist output channels. At the same time, they also have an oil-proof function, improving the problem that e-liquid in existing cartridges and electronic atomizing devices can easily enter the air intake channel through various gaps or holes during use, damaging the circuit board, causing the electronic atomizing device to malfunction, seriously affecting its reliability and lifespan, and impacting the user's taste.

[0057] 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.
