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 the current booming e-cigarette industry, the performance of e-liquid cartridges, as a key component of e-cigarettes, directly impacts the user experience. Existing cartridge structures generally include an e-liquid reservoir, an atomizing chamber for vaporization, an airflow channel, and an exhaust channel. With current cartridge structures, e-liquid can easily enter the airflow and exhaust channels through various gaps and pores during use. Once e-liquid enters the airflow channel, it can potentially seep into the circuit board area. This can not only damage the circuit board, causing the e-cigarette to malfunction, but also potentially lead to short circuits and other safety hazards, severely affecting the reliability and lifespan of the e-cigarette, and significantly impacting the user's taste. Summary of the Invention

[0003] This application provides a cartridge and an electronic atomizing device, aiming to improve 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 atomizer to malfunction, seriously affecting the reliability and lifespan of the electronic atomizer, and affecting the user's taste.

[0004] Therefore, this application provides a tobacco cartridge and an electronic atomizing device, including: a tobacco cartridge shell and a bottom cover, the bottom cover being connected to the bottom of the tobacco cartridge shell, and the bottom cover having a first air intake channel; the tobacco cartridge shell having:

[0005] Fog exit channel;

[0006] An oil storage chamber, which surrounds the mist outlet channel, is used to store e-liquid;

[0007] The bracket connects to the oil storage chamber and contains an atomizing core assembly for atomizing e-liquid. The bracket has openings at both ends, with the first end connecting to the mist outlet channel and the second end connecting to the bottom cover. An oil-proof and breathable membrane is provided on the first air inlet channel facing the bracket.

[0008] Furthermore, the inner wall of the cartridge shell is connected with a sealing silicone, which divides the oil storage cavity into a sliding space and an oil storage space for storing e-liquid. Several oil inlet holes are provided on the peripheral side wall in the middle of the bracket. The bracket passes through the sealing silicone and can move up and down in the mist outlet channel.

[0009] When not in use, the sealing silicone seals the oil inlet. When in use, the bottom cover is pushed, and the bottom cover moves the bracket along the direction close to the oil storage space until the oil inlet is disengaged from the sealing silicone. The e-liquid in the oil storage space then enters the atomizing core assembly of the bracket through the oil inlet.

[0010] Furthermore, a limiting groove is provided in the first end of the bracket, and an oil-proof and breathable membrane is provided in the limiting groove.

[0011] Furthermore, the mist outlet channel includes a first channel and a second channel that are interconnected. The opening of the first channel is connected to the mouthpiece, and the inner wall of the opening of the second channel away from the mouthpiece is sealed to the outer periphery of the first end of the bracket.

[0012] Furthermore, the outer peripheral sidewall of the first end of the bracket is provided with several sealing protrusions, and the sealing protrusions are sealed to the inner wall of the second channel.

[0013] Furthermore, the diameter of the second channel is larger than that of the first channel; the second channel has reserved space for movement. When not in use, the height of the space for movement is the same as the height of the bottom cover protruding from the cartridge shell. When in use, the bottom cover is pushed up and connected to the bottom of the cartridge shell, so that the limiting part at the first end of the bracket abuts against the connection between the second channel and the first channel.

[0014] Furthermore, the cartridge shell is also provided with a support base, and the second end of the support is embedded in the support base; the support base is provided with a second air intake channel, one end of the second air intake channel is connected to the inside of the support and connected to the mist outlet channel, and the other end of the second air intake channel is connected to the first air intake channel.

[0015] Furthermore, the outer periphery of the bottom cover is provided with a protrusion, and the cartridge shell is provided with a first limiting hole and a second limiting hole. When the protrusion is limited to the second limiting hole, the sealing silicone seals the oil inlet. When the protrusion is limited to the first limiting hole, the oil inlet is disengaged from the sealing silicone, and the e-liquid in the oil storage chamber can enter the atomizing core assembly of the bracket through the oil inlet.

[0016] Furthermore, the bottom cover is provided with two guide posts, which penetrate the bottom bracket and the sealing silicone. In use, the guide posts move upward, and their ends do not exceed the top surface of the sealing silicone.

[0017] The e-cigarette cartridge and electronic atomizing device provided in this application include a cartridge shell and a bottom cover. The bottom cover is detachably connected to the bottom of the cartridge shell and has a first air intake channel. The cartridge shell contains a vapor outlet channel, an oil storage chamber, and a support. The oil storage chamber surrounds the vapor outlet channel and is used to store e-liquid. The support connects to the oil storage chamber and houses an atomizing core assembly for atomizing the e-liquid. The support has openings at both ends; the first end connects to the vapor outlet channel, and the second end connects to the bottom cover. An oil-proof and breathable membrane is provided in the first air intake channel facing the support. The oil-proof and breathable membrane in the first air intake channel has good air permeability, ensuring smooth airflow into the air intake channel. Simultaneously, the membrane also has an oil-proof function, effectively preventing e-liquid from entering the first air intake channel and reaching the circuit board, contaminating the circuit board, and disrupting the normal operation of the electronic atomizing device, thus improving the reliability and lifespan of the device.

[0030] Example 1:

[0031] In one embodiment, such as Figures 1 to 4 As shown in the illustration, this application provides a tobacco cartridge, including: a cartridge shell 1 and a bottom cover 2. The bottom cover 2 is detachably connected to the bottom of the cartridge shell 1, and a first air intake channel 20 is provided on the bottom cover 2; specifically, the first air intake channel 20 is located in the middle of the bottom cover 2. The cartridge shell 1 contains: a mist outlet channel 3 connected to a mouthpiece 300; an oil storage chamber 4 surrounding the mist outlet channel 3; a sealing silicone 5 at the bottom of the oil storage chamber 4 for sealing the oil storage chamber 4; and a bracket 6 containing an atomizing core assembly 7. The bracket 6 has openings at both ends, with the first end 61 of the bracket 6 connecting to the mist outlet channel 3 and the second end 62 connecting to the bottom cover 2; specifically, the bracket 6 connects the mist outlet channel 3 and the first air intake channel 20. An oil-proof and breathable membrane 100 is provided on the first air intake channel 20 facing the bracket 6. The oil-proof and breathable diaphragm 100 has good air permeability, which can ensure that air can smoothly enter the air intake channel. At the same time, the oil-proof and breathable diaphragm 100 also has an oil-proof function, which can effectively prevent grease from entering the first air intake channel 20 and reaching the circuit board, thus preventing contamination of the circuit board and improving the reliability and service life of the equipment.

[0032] Optionally, as shown in the figure, the bracket 6 has several oil inlet holes 60 on its peripheral sidewall in the middle part; the bracket 6 passes through the sealing silicone 5, connects to the mist outlet channel 3, and can move up and down in the mist outlet channel 3.

[0033] Specifically, in the unused state, the oil inlet 60 is sealed with silicone 5. In the used state, the bottom cover 2 is pushed, which causes the bracket 6 to move vertically. The bottom cover 2 pushes the bracket 6 upward until the oil inlet 60 is separated from the silicone 5, allowing the e-liquid in the oil storage chamber 4 to enter the atomizing core assembly 7 of the bracket 6 through the oil inlet 60. The atomizing core assembly 7 includes absorbent cotton, atomizing core bracket, oil storage cotton, and heating wire wrapped around the oil storage cotton. When the oil inlet 60 leaks out of the silicone 5, the e-liquid in the oil storage chamber 4 quickly enters the absorbent cotton and then the oil storage cotton. When the user vapes, the microphone activates the heating wire to heat the e-liquid in the oil storage cotton, turning it into aerosol particles that are discharged from the vapor outlet channel 3.

[0034] Optionally, a limiting groove 610 is provided in the first end 61 of the bracket 6, and an oil-proof and breathable membrane 100 is disposed in the limiting groove 610. Specifically, in order to better prevent e-liquid from entering the mist outlet channel 3, an oil-proof and breathable membrane 100 is also provided in the first end 61 of the bracket 6. It can be understood that, in order to better fix the oil-proof and breathable membrane 100, a limiting groove 610 is provided in the first end 61 of the bracket 6, and the oil-proof and breathable membrane 100 is disposed in the limiting groove 610.

[0035] Optionally, the mist outlet channel 3 includes a first channel 301 and a second channel 302 that are interconnected. The opening of the first channel 301 is connected to the mouthpiece 300, and the inner wall of the opening of the second channel 302 away from the mouthpiece 300 is sealed to the outer periphery of the first end 61 of the bracket 6.

[0036] Specifically, the mist outlet channel 3 is configured as a pipe structure that increases from top to bottom. The mist outlet channel 3 is configured as two sections. The first channel 301 is connected to the mouthpiece 300, and the second channel 302 is used to connect to the first end 61 of the bracket 6. The first end 61 of the bracket 6 can move back and forth within the second channel 302.

[0037] Optionally, a plurality of sealing protrusions 611 are provided on the outer peripheral wall of the first end 61 of the bracket 6, and the sealing protrusions 611 are sealed to the inner wall of the second channel 302.

[0038] Specifically, by setting a number of sealing protrusions 611 on the outer peripheral wall of the first end 61, the sealing protrusions 611 and the inner wall of the second channel 302 are sealed together, so that the e-liquid cannot flow into the mist channel 3.

[0039] Optionally, such as Figure 1 As shown, the diameter of the second channel 302 is larger than the diameter of the first channel 301; the second channel 302 has a reserved space 303 for the first end 61 of the bracket 6 to move up and down.

[0040] Specifically, when not in use, the reserved height of the movable space 303 is the same as the height of the movable part of the bottom cover 2 that protrudes from the cartridge shell 1. At this time, the first end 61 of the bracket 6 is sealed to the lower opening of the second channel 302. When in use, the bottom cover 2 is pushed upward, so that the bottom opening of the bottom cover 2 and the cartridge shell 1 are fully engaged, causing the first end 61 of the bracket 6 to move upward and press against the connection 304 between the second channel 302 and the first channel 301. The shape of the connection 304 is designed to be the same as the shape of the top of the first end 61, so that when the bottom cover 2 is pushed upward, the first end 61 and the connection 304 are sealed together.

[0041] Optionally, the cartridge casing 1 is further provided with a support base 8, and the second end 62 of the support 6 is embedded in the support base 8. Specifically, the support base 8 is provided with a structure that matches the second end 62, so that the second end 62 of the support 6 is embedded in the support base 8, thereby better fixing the second end 62 of the support 6.

[0042] In addition, a connection structure for the bottom cover 2 is provided on the outer peripheral wall of the support base 8, so that the bottom cover 2 and the outer peripheral wall of the support base 8 are snapped together and fixed. Under the action of external force, the bottom cover 2, the support base 8 and the support 6 can move up and down together.

[0043] Optionally, the bracket base 8 is provided with a second air intake channel 80. One end of the second air intake channel 80 is connected to the interior of the bracket 6, and the other end of the second air intake channel 80 is connected to the first air intake channel 20 of the bottom cover 2. It can be understood that external gas enters from the first air intake channel 20 of the bottom cover 2, passes through the second air intake channel 80 into the atomizing core assembly 7 inside the bracket 6, flows into the mist outlet channel 3 from the first end 61 of the bracket 6, and flows out from the mist outlet channel 3 through the mouthpiece 300 to reach the user.

[0044] Furthermore, the outer periphery of the bottom cover 2 is provided with a protrusion 21, and the cartridge shell 1 is provided with a first limiting hole 10 and a second limiting hole 11. When the protrusion 21 is limited to the second limiting hole 11, the sealing silicone 5 seals the oil inlet 60. When the protrusion 21 is limited to the first limiting hole 10, the oil inlet 60 is disengaged from the sealing silicone 5, and the e-liquid in the oil storage chamber 4 can enter the atomizing core assembly 7 of the bracket 6 through the oil inlet 60.

[0045] Specifically, when not in use, the protrusion 21 is positioned at the second limiting hole 11, causing the bottom cover 2 to leak out from the bottom of the cartridge shell 1 and being positioned in the state where the sealing silicone 5 seals the oil inlet 60, preventing e-liquid from entering the atomizing core assembly 7 before use.

[0046] When in use, the protrusion 21 is positioned at the first limiting hole 10, causing the bottom cover 2 to move upward and be tightly fixed to the bottom of the cartridge shell 1, so that the oil inlet 60 leaks out from the sealing silicone 5 and is exposed in the oil storage chamber 4, allowing the e-liquid to quickly enter the oil storage cotton of the atomizing core assembly 7, and the heating wire atomizes the e-liquid in the oil storage cotton when the microphone is activated.

[0047] Furthermore, the bottom cover 2 is provided with two guide posts 9, which pass through the bracket base 8 and the sealing silicone 5. In use, the guide posts 9 move upward, making the movement of the bottom cover 2 and the bracket 6 more stable. In addition, in the use state, the upper end of the guide post 9 does not exceed the top surface of the sealing silicone 5.

[0048] In summary, in the initial state, the oil inlet 60 of the bracket 6 is located at the sealing silicone 5. The sealing silicone 5 seals the oil inlet 60, effectively preventing e-liquid from flowing into the oil reservoir cotton, thus avoiding e-liquid leakage from the oil reservoir cotton into the air intake channel. An oil-proof and breathable membrane 100 is installed inside the first air intake channel 20. The oil-proof and breathable membrane 100 has good air permeability, ensuring smooth airflow into the air intake channel. Simultaneously, the oil-proof and breathable membrane 100 also has an oil-proof function, effectively preventing e-liquid from entering the first air intake channel 20 and reaching the circuit board, contaminating the circuit board, and disrupting the normal operation of the electronic atomizing device, thereby improving the reliability and lifespan of the device. An oil-proof and breathable membrane 100 is also installed inside the first end 61 of the bracket 6 to prevent e-liquid from entering the mist outlet channel 3, improving the user's taste experience.

[0049] Example 2:

[0050] An electronic atomizing device is characterized by comprising a cartridge. The cartridge also has an electrode plate at its bottom for electrically connecting to a circuit board assembly within the device. The device further includes a device housing a microphone, a circuit board assembly, and a battery assembly. The microphone controls the heating coil's activation and deactivation. During inhalation, the microphone senses a suction signal and activates the heating coil, which atomizes the e-liquid in the oil reservoir. When inhalation stops, the microphone deactivates the heating coil. In use, pushing the bottom cover 2 causes the support 6 to move upwards until the oil inlet 60 disengages from the sealing silicone 5, allowing the e-liquid in the oil reservoir 4 to enter the oil reservoir in the support 6 through the oil inlet 60. Inserting the cartridge into the device completes the atomizing process. The device's oil-proof and breathable membrane enhances the barrier effect, preventing e-liquid from entering the air intake channel, ensuring the circuit board is not contaminated by e-liquid, improving the device's reliability and lifespan, and enhancing the user's taste experience.
