Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, in particular to a cigarette cartridge and an electronic cigarette using the same. Background Art

[0002] At present, in the existing electronic cigarettes, after injecting tobacco oil into the oil storage chamber of the tobacco cartridge, bubbles will be discharged from the oil absorption part in the oil storage chamber during the process of absorbing tobacco oil. These bubbles gather in the oil storage chamber and cannot be discharged, which will cause the oil absorption part to absorb oil slowly and fail to reach a saturated state, thereby causing the heating core to absorb insufficient oil and cause dry burning. In addition, in order to test the sealing of the oil storage chamber before oil is filled, the tobacco cartridge will be vacuum tested. During the vacuum test, part of the air in the oil storage chamber and the oil absorption part will be extracted through the oil inlet hole, which will cause the oil absorption part to shrink, and the gas cannot enter the oil storage chamber to maintain the air pressure balance and restore the oil absorption part to its original shape. After oil filling, the tobacco oil in the oil storage chamber cannot be completely absorbed, and thus it is deposited in the oil storage chamber. Over time, it seeps out of the oil storage chamber and causes oil leakage. Utility Model Content

[0024] like Figure 1-3As shown, the utility model provides a cigarette cartridge, including a cigarette cartridge body 7, the cigarette cartridge body 7 has an oil storage chamber 301 for storing cigarette oil, an oil suction piece 2 arranged in the oil storage chamber 301 for absorbing cigarette oil and an exhaust structure for exhausting gas, an air discharge portion 706 is formed in the oil suction piece 2, the exhaust structure has an air gathering groove 601, an air flow collecting and distributing portion communicating with the air gathering groove 601, and an exhaust space 701 communicating with the air flow collecting and distributing portion, the cigarette cartridge body 7 has an air outlet portion 707, and the air discharge portion 706 is communicated with the air outlet portion 707 and the exhaust space 701. By designing the exhaust structure and the air leakage part 706, when the oil-absorbing component 2 absorbs the tobacco oil in the oil storage chamber 301, the internal air can be discharged through the exhaust structure and the air leakage part 706, preventing the air inside the oil-absorbing component 2 from being unable to be discharged through the oil storage chamber 301, causing the oil-absorbing component 2 to absorb oil slowly and fail to reach a saturated state, thereby causing the heating core 5 to absorb insufficient oil and cause dry burning. After the vacuum test of the tobacco cartridge, the oil-absorbing component 2 shrinks, and the gas can enter the oil storage chamber 301 through the air leakage part 706 and the exhaust structure to restore the oil-absorbing component 2 to its original shape, preventing the oil-absorbing component 2 from shrinking and the tobacco oil in the oil storage chamber 301 from being completely absorbed, thereby seeping out of the oil storage chamber 301 and causing oil leakage.

[0025] In some embodiments, the air gathering groove 601 is provided on the corresponding bottom wall of the oil storage chamber 301, the airflow gathering and distributing portion is provided on the corresponding wall surrounding the oil storage chamber 301, and the exhaust space 701 is provided on the corresponding top wall of the oil storage chamber 301. It should be noted that after the oil is injected into the oil storage chamber 301, the air within the oil storage chamber 301 and the air within the oil absorbing member 2 are squeezed against the bottom wall of the oil storage chamber 301 under the pressure of the oil, and then converge into the air gathering groove 601. Thereafter, the air is diverted through the airflow gathering and distributing portion and moves toward the top wall of the oil storage chamber 301, then enters the exhaust space 701, and is subsequently discharged through the air vent 706 and the air outlet 707.

[0026] In some embodiments, the air discharge portion 706 is formed by the gap 702 and / or the spacing space 703; the air outlet portion 707 is formed by the air outlet hole 101 and / or the air outlet channel 103, and the air flow distribution portion is formed by the first air channel 704 and the second air channel 705. In this embodiment, the air discharge portion 706 is formed by the gap 702 and the spacing space 703.

Among them, the gap 702 is used to connect the exhaust space 701, and the spacing space 703 is used to connect the gap 702 and the air outlet portion 707. In this embodiment, the air outlet portion 707 is formed by the air outlet hole 101 and the air outlet channel 103. The air outlet channel 103 is used to connect the spacing space 703 and the air outlet hole 101. The air outlet hole 101 is used to discharge the gas out of the smoke cartridge body 7.

A smoking channel 804 is provided in the suction nozzle 803, which is connected to each air outlet 101, for sucking the smoke discharged from each air outlet 101 into the mouth. An air inlet hole 805 is provided at the bottom of the power supply body 8, which is connected to each air inlet channel 602 of the cigarette cartridge body 7, for allowing the air flow to enter each mist channel 401 and then drive the smoke through the spacing space 703 into the air outlet channel 103, and then discharge the cigarette cartridge body 7 through the air outlet 101, and finally enter the user's mouth through the smoking channel 804 to be inhaled.

[0037] like Figure 5 As shown, the specific implementation description of the airflow direction when the cartridge body 7 of the electronic cigarette of this embodiment is exhausted is as follows: after the smoke oil is injected into the oil storage chamber 301, the air in the oil storage chamber 301 and the air in the oil suction component 2 will be squeezed to the bottom end of the oil storage chamber 301 under the pressure of the smoke oil, and then converge into the air gathering groove 601 on the second oil sealing component 6, and then the air is diverted and introduced into the exhaust space 701 through the first air channel 704 and the second air channel 705, and then introduced into the corresponding air outlet channel 103 through each gap 702 and each corresponding spacing space 703, and then discharged from the cartridge body 7 through the air outlet hole 101, thereby preventing the air inside the oil suction component 2 from being unable to be discharged through the oil storage chamber 301, causing the oil suction component 2 to absorb oil slowly and unable to reach a saturated state, thereby causing the heating core 5 to absorb insufficient oil and dry burning.

[0038] like Figure 6As shown, the direction of the airflow after the main body 7 of the cartridge of the electronic cigarette of this embodiment is vacuumed is specifically described. After the vacuum test, part of the air in the oil storage chamber 301 and the oil absorbing component 2 will be extracted through the oil inlet hole 403, causing the oil absorbing component 2 to shrink. At this time, the outside air can enter the corresponding air outlet channel 103 through each air outlet hole 101, and then enter the corresponding spacing space 703 through each air outlet channel 103, and then enter the exhaust space 701 from the corresponding gap 702 through each spacing space 703 to various parts of the oil storage chamber 301, thereby balancing the air pressure in the oil storage chamber 301 and restoring the oil absorbing component 2 to its original shape, thereby preventing the oil absorbing component 2 from shrinking after the vacuum test, and preventing the gas from entering the oil storage chamber 301 to restore the oil absorbing component 2 to its original shape, resulting in the oil in the oil storage chamber 301 not being completely absorbed, and seeping out of the oil storage chamber 301 to cause oil leakage.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
