Description

Technical Field

[0001] This utility model relates to the technical field of electronic atomization devices, specifically a leak-proof oil fume cartridge and an electronic atomization device. Background Technology

[0002] Electronic vaporizers are electronic products that mimic cigarettes, producing smoke, taste, and sensations similar to cigarettes. They generate vapor by heating and vaporizing e-liquid made from chemicals and various flavorings. By controlling the composition of the e-liquid, the nicotine content can be controlled. Therefore, e-cigarettes, primarily used for smoking cessation and as a substitute for cigarettes, have been rapidly promoted and used.

[0003] Currently, electronic atomizing devices generally suffer from the following problems: After use, condensed e-liquid is generated in the vapor channel of the atomizer. Under the influence of gravity, the condensate flows into the battery compartment through the air intake channel at the bottom of the atomizer, which is connected to the vapor channel. Then, after accumulating in the battery compartment, the condensate flows into the airflow sensing channel inside the battery compartment, which is used to drive the microphone. This affects the permeability of the airflow sensing channel, prevents the microphone from working properly, and causes the condensate to seep into the microphone through the airflow sensing channel, resulting in a short circuit.

[0004] Therefore, existing technologies need to be improved. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application proposes a leak-proof oil fume cartridge and an electronic atomizing device.

[0006] Firstly, a leak-proof oil fume cartridge employs the following technical solution:

[0007] A leak-proof oil fume cartridge includes a shell, a receiving chamber inside the shell, an oil storage chamber and an atomizer inside the receiving chamber, the atomizer being disposed in the oil storage chamber, an air inlet communicating with the atomizer being disposed at the bottom of the shell, and a baffle cylinder being disposed in the receiving chamber, the baffle cylinder being communicating with the air inlet to allow external air to enter the receiving chamber from the baffle cylinder.

[0008] By adopting the above technical solution, after the electronic atomizing device is used up, the vapor remaining in the vapor outlet channel will liquefy upon cooling and move downwards under the action of gravity. As the device is used, the condensate will drip from the air inlet of the atomizer to the bottom of the receiving chamber. At this time, the outer wall of the baffle tube will block the condensate dripping to the bottom of the receiving chamber, preventing the condensate from flowing out of the cartridge from the air inlet. This can minimize the possibility of the cartridge leaking liquid and causing damage to the microphone.

[0009] Preferably, the upper end of the baffle cylinder is provided with an extension, which is used to increase the travel distance of external air from the air inlet into the receiving chamber.

[0010] Preferably, the extension is an extension tube, which is inserted into the inner wall of the blocking cylinder, and an air outlet communicating with the air inlet is provided on the side wall of the extension tube extending out of the blocking cylinder.

[0011] By adopting the above technical solution, when the electronic atomizing device is used for a long time, the condensate will not accumulate in the containment chamber. When the condensate accumulation height exceeds the height of the blocking cylinder, the condensate will still leak out from the air inlet. Therefore, the extension tube is set up, and an air outlet connected to the air inlet is provided on the side wall of the extension tube, which is equivalent to further raising the height of the air inlet, thereby further preventing the condensate from leaking.

[0012] Preferably, the outer wall of the extension tube is tightly fitted and abuts against the inner wall of the blocking cylinder.

[0013] By adopting the above technical solution, since the e-cigarette cartridge is carried by the user at all times, it may be inverted. Therefore, the condensate at the bottom of the receiving chamber may splash as the e-cigarette cartridge moves. If the e-cigarette cartridge is inverted, the condensate will slide along the extension tube, possibly sliding to the air outlet, causing blockage of the air outlet or even causing the condensate to flow from the air outlet to the air inlet and out of the e-cigarette cartridge. Therefore, by installing the extension tube by tightly fitting the outer wall of the extension tube to the inner wall of the baffle tube, the extension tube can be disassembled for cleaning. The condensate remaining on the inner and outer walls of the extension tube can be cleaned, ensuring the cleanliness of the extension tube and preventing condensate from flowing out of the extension tube.

[0014] Preferably, a limiting ring is provided on the inner wall of the blocking cylinder, and the upper end face of the limiting ring is used to abut against the extension tube.

[0015] By adopting the above technical solution, due to the setting of the limiting ring, when the extension tube is inserted into the blocking cylinder, the lower end of the extension tube will abut against the upper end face of the limiting ring to support the extension tube and prevent the extension tube from slipping out of the blocking cylinder.

[0016] Preferably, the extension tube has a limiting notch at the side opening that abuts against the limiting ring, and the upper end face of the limiting ring has a limiting block, which is used to be inserted into the limiting notch.

[0017] By adopting the above technical solution, due to the setting of the limiting block and the cooperation between the limiting block and the limiting notch, the extension tube does not easily rotate after being installed on the blocking cylinder. This can prevent gaps from being generated between the outer wall of the extension tube and the inner wall of the blocking cylinder due to rotation, and minimize the leakage of condensate from the gap between the extension tube and the blocking cylinder.

[0018] Preferably, the side wall of the housing is provided with an oil injection hole that communicates with the oil storage cavity, and an oil injection plug is tightly inserted into the oil injection hole.

[0019] By adopting the above technical solution, due to the setting of the oil filling hole and the oil filling plug, when the e-liquid in the oil storage chamber is used up, the oil filling plug can be pulled out, and then the oil filling hole can be placed upwards to inject e-liquid into the oil storage chamber. Finally, the oil filling plug can be inserted back into the oil filling hole, which allows the e-liquid cartridge to be reused, thereby reducing the user's usage cost.

[0020] Preferably, the extension tube and the oil storage cavity are arranged in a left-right distribution.

[0021] By adopting the above technical solution, compared with the extension tube and oil storage chamber being arranged vertically, this design can reduce the volume occupied by the storage chamber, shorten the length of the e-cigarette cartridge, increase aesthetics, and make it convenient for users to carry.

[0022] Secondly, an electronic atomizing device employs the following technical solution:

[0023] An electronic atomizing device, comprising a cartridge.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. After the electronic atomizer is used, the vapor remaining in the vapor outlet channel will liquefy upon cooling and move downwards under gravity. As it is used, the condensate will drip from the air inlet of the atomizer to the bottom of the receiving chamber. At this time, the outer wall of the baffle tube will block the condensate dripping to the bottom of the receiving chamber, preventing the condensate from flowing out of the cartridge from the air inlet. This can minimize the possibility of the cartridge leaking liquid and damaging the microphone.

[0026] 2. When using the electronic atomizing device for a long time, condensate will accumulate in the containment chamber. When the condensate accumulation height exceeds the height of the baffle tube, the condensate will still leak out from the air inlet. Therefore, the extension tube is designed, and an air outlet connected to the air inlet is provided on the side wall of the extension tube. This is equivalent to further raising the height of the air inlet, thereby further preventing the condensate from leaking. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0033] This application discloses an anti-leakage oil fume cartridge. (Refer to...) Figures 1 to 3 The leak-proof e-cigarette cartridge includes a shell 2, inside which is a receiving chamber 21. The receiving chamber 21 contains an e-liquid storage chamber 23 and an atomizer. The e-liquid storage chamber 23 is used to hold e-liquid, and the atomizer is located in the e-liquid storage chamber 23 to atomize the e-liquid. The air inlet of the atomizer is connected to the receiving chamber 21. An air inlet 22 is located at the bottom of the shell 2, with its axis parallel to the vertical direction. The air inlet 22 is connected to the air inlet of the atomizer. A baffle 3 is located in the receiving chamber 21 to block... The tube 3 has a circular cross-section. The blocking tube 3 is integrally set at the bottom of the receiving chamber 21. The blocking tube 3 is located at the edge of the air inlet 22 and is coaxial with the air inlet 22. Through the blocking effect of the outer wall of the blocking tube 3, the air inlet 22 is raised so that the condensate falling at the bottom of the receiving chamber 21 cannot flow directly out of the air inlet 22. This can block the condensate and prevent the condensate from flowing directly out of the cartridge 1 from the air inlet 22, thereby minimizing the possibility of leakage of the cartridge 1 and damage to the microphone.

[0034] Reference Figure 2 and Figure 3In order to further improve the blocking effect of the blocking cylinder 3, an extension is provided at the upper end of the blocking cylinder 3. The extension is used to increase the travel distance of external air from the air inlet 22 to the receiving chamber 21, which is equivalent to further raising the height of the air inlet 22. In this embodiment, the extension is in the form of an extension tube 31. The extension tube 31 is inserted at the upper end of the blocking cylinder 3 and is coaxial with the blocking cylinder 3. The extension tube 31 extends away from the air inlet 22. An air outlet 32 ​​is provided on the side wall of the extension tube 31. External air enters through the air inlet 22 and then exits through the air outlet 32, and finally moves to the air inlet end of the atomizer. This design further raises the height of the external gas flowing into the cartridge 1, which can further prevent condensate from flowing out of the cartridge 1 from the air inlet 22.

[0035] Reference Figure 2 and Figure 3 Since the cartridge 1 is placed in the user's pocket when not in use, it may be in various positions during the user's movement, which may cause the condensate at the bottom of the receiving chamber 21 to splash onto the outer wall of the extension tube 31. If the cartridge 1 is inverted, the condensate hanging on the outer wall of the extension tube 31 will flow towards the air outlet 32, causing the condensate to block the air outlet 32. The condensate may even flow from the air outlet 32 ​​to the air inlet 22, causing the condensate to leak. Therefore, to avoid this situation, one end of the extension tube 31 is tightly inserted into the blocking tube 3. When it needs to be removed for cleaning, it can be pulled off by force.

[0036] Reference Figure 2 and Figure 3 In this embodiment, to prevent the extension tube 31 from moving relative to the blocking cylinder 3, a limiting ring 4 is provided on the inner wall of the blocking cylinder 3. The limiting ring 4 is located on the lower side of the blocking cylinder 3, and is circular in shape. The limiting ring 4 is coaxially arranged with the blocking ring, and the upper end face of the limiting ring 4 is used to abut against the extension tube 31 to restrict the movement of the extension tube 31 in the vertical direction and prevent the extension tube 31 from falling out of the cartridge 1 from the air inlet 22. In addition, a limiting block 41 is provided on the upper end face of the limiting ring 4. Two limiting blocks 41 are provided, and the two limiting blocks 41 are symmetrically distributed along the axis of the limiting ring 4. A limiting notch 33 adapted to the limiting block is provided at the lower end of the extension tube 31. The limiting notch 33 is used for the insertion of the limiting block 41. Therefore, when the extension tube 31 abuts against the limiting ring 4, the limiting block 41 will be inserted into the limiting notch 33 to restrict the rotation of the extension tube 31. Since the extension tube 31 is tightly inserted into the blocking cylinder 3, the rotation of the extension tube 31 will cause a gap between the outer wall of the extension tube 31 and the inner wall of the blocking cylinder 3. Therefore, the setting of the limiting block 41 and the limiting notch 33 can prevent the gap between the extension tube 31 and the blocking cylinder 3 from causing the condensate to flow out from the gap.

[0037] Reference Figure 2 and Figure 3 To enable the reusability of the cartridge 1, an oil filling hole 24 is provided on the side wall of the housing 2. The oil filling hole 24 is connected to the oil storage chamber 23 in the receiving chamber 21. An oil filling plug 5 is tightly inserted into the oil filling hole 24. The oil filling plug 5 is made of elastic material. Therefore, when oil filling is required, the cartridge 1 is first placed horizontally with the oil filling hole 24 facing upwards for oil filling. After oil filling is completed, the oil filling plug 5 is inserted into the oil filling hole 24. This allows the cartridge 1 to be reused, thereby reducing the user's operating costs. In this embodiment, the oil filling plug 5 is also provided with a connecting part, which is fixedly inserted into the housing 2. Therefore, when the oil filling plug 5 opens the oil filling hole 24, the oil filling plug is still connected to the housing 2, preventing the oil filling plug 5 from being lost.

[0038] In addition, in this embodiment, the extension tube 31 and the oil storage cavity 23 are arranged in a left-right distribution. This design can reduce the overall length of the e-cigarette cartridge 1, increase its aesthetics, and make it convenient for users to carry.

[0039] This application also discloses an electronic atomizing device, as described in the embodiments below. Figures 1 to 3 Including the leak-proof oil fume cartridge 1, the electronic atomizing device of this embodiment also has the above-mentioned beneficial effects, which will not be described in detail here.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
