[0002] The cartridge is the core component of the electronic atomization device, which has an oil tank for storing the oil, an atomization core for heating and atomizing the oil, and other structures. The atomized oil easily forms condensate on the inner wall of the mouthpiece channel, and flows to the condensation chamber at the bottom of the cartridge under the action of gravity.

Therefore, long-term use will cause a large amount of residual liquid in the condensation chamber. The condensation chamber is connected to the external air inlet of the cartridge, so the problem of residual liquid leaking from the air inlet is prone to occur. In summary, there is room for improvement in existing cartridges. Utility Model Content

[0030] See attached Figure 1-4 , shown is a cigarette cartridge with a condensation chamber having a liquid return function, the cigarette cartridge 1 comprises a main shell, an atomizer core 2, the atomizer core 2 is installed in the main shell, the lower part of the main shell has a bracket 3, the bottom end of the atomizer core 2 is inserted on the bracket 3, the bottom of the main shell is formed with a condensation chamber 4 located below the bracket 3, the bracket 3 is provided with an air flow hole 300 connecting the condensation chamber 4 and the atomizer core 2; the bottom of the bracket 3 is provided with a reflux groove 5, the upper end of the reflux groove 5 extends to the air flow hole 300, the lower end of the reflux groove 5 extends toward the bottom of the condensation chamber 4, and a gap 500 with liquid locking capability is formed between the reflux groove 5 and the bottom of the condensation chamber 4.
[0031] The main shell of the cigarette cartridge 1 usually includes a shell body 100 and a base 101. The shell body 100 has an oil tank inside. The bottom of the oil tank is blocked by a bracket 3 connected to the shell body 100. The atomizer core 2 is inserted into the oil tank, and its bottom end is connected to the bracket 3. The base 101 connected to the shell body 100 is installed below the bracket 3. Both the bracket 3 and the base 101 can be assembled with the shell body 100 by tight fit, snap-fit, etc. The middle part of the base 101 is concave to form a condensation chamber 4. External air flows into the condensation chamber 4 through the air inlet, and then flows to the atomizer core 2 through the air flow hole 300. The smoke generated by the atomization of the smoke oil through the atomizer core 2 flows to the mouthpiece. Part of the smoke will form condensate on the mouthpiece channel. The condensate falls through the air flow hole 300 under the action of gravity and is stored in the condensation chamber 4. At the same time, a small amount of smoke oil will leak into the condensation chamber 4.
[0032] Under the suction force of the user, the residual liquid in the condensation chamber 4 is sucked into the reflux groove 5. The gap 500 between the lower end of the reflux groove 5 and the bottom of the condensation chamber 4 is narrow enough. Because the residual liquid has tension, the residual liquid entering is retained in the reflux groove 5 and basically cannot actively flow out through the gap. After many experiments, it is known that the width range of the gap 500 is less than or equal to 0.1mm, and the preferred value is 0.1mm. When the electronic atomization device is working, the residual liquid in the cavity will flow back upward along the reflux groove 5. After multiple suction actions by the user, the residual liquid will eventually reach the atomization core 2 and be atomized.
[0033] After many experiments, it is found that the cross-sectional area of the reflux groove 5 is less than or equal to 1mm 2 For example, the cross section of the reflux groove 5 is square, and the groove width and groove depth are both less than or equal to 1 mm, and the preferred value is 1 mm. During the reflux process of the residual liquid, due to its viscosity, it can adhere to the wall of the reflux groove 5 and slowly flow upward when the user sucks. Even if the user's sucking action is intermittent, the residual liquid will not fall back due to gravity.
[0034] Preferably, the side of the reflux groove 5 facing the air flow hole 300 is open. Condensate and leaked e-liquid fall into the condensation chamber 4 through the air flow hole 300. The side of the reflux groove 5 facing the air flow hole 300 is designed to be open, which is conducive to more and faster residual liquid in the chamber entering the reflux groove 5. The airflow generated by the user's inhalation action forms a negative pressure on the condensation chamber 4 and the reflux groove 5. According to the Bernoulli effect, the residual liquid in the chamber will flow back upward along the narrower reflux groove 5.
[0035] See attached Figure 7 In some embodiments, the bottom of the condensation chamber 4 is provided with two bosses 7 for mounting the electrode nails 6, and a spacing area 700 is provided between the two bosses 7, and the spacing area 700 is located below the air flow hole 300; the bottom of the bracket 3 is provided with two reflux grooves 5, and the two reflux grooves 5 are respectively located at the two ends of the spacing area 700.
[0036] The cartridge 1 is electrically connected to the host through the electrode nail 6. An electrode nail 6 is installed on each of the two bosses 7. The height difference of the bosses 7 can prevent the residual liquid in the condensation chamber 4 from leaking from the edge of the electrode nail 6. The condensed liquid and the leaked smoke oil will directly fall into the spacer area 700 of the condensation chamber 4 through the air flow hole 300. The two bosses 7 cooperate with the two reflux grooves 5 to have a certain enclosure effect on the spacer area 700, which is conducive to concentrating the residual liquid in the spacer area 700 and facilitating the residual liquid to flow to the reflux groove 5.
[0037] In order to provide the reflux groove 5, the bottom of the bracket 3 can be extended toward the condensing chamber 4 as a whole, but this method will cause a greater obstruction to the air entering the atomizer core 2 through the air flow hole 300. Figure 5-6In some embodiments, two extension blocks 303 extending toward the condensing chamber 4 are provided at the bottom of the bracket 3, and the reflux groove 5 is formed on each of the extension blocks 303. By providing the extension blocks 303 at the part of the bracket 3, the reflux groove 5 is provided, and sufficient circulation space between the condensing chamber 4 and the air flow hole 300 is reserved, so as to ensure that sufficient external air enters the atomizing core 2.
[0038] In some embodiments, the bracket 3 is provided with a plug-in cavity 301, the air flow hole 300 is formed in the middle of the bottom of the plug-in cavity 301, and the side wall of the upper part of the air flow hole 300 extends out of the bottom surface of the plug-in cavity 301; the bottom end of the atomizer core 2 is inserted into the plug-in cavity 301, and a sealing ring is arranged between the two, and the upper part of the air flow hole 300 is inserted into the bottom end of the atomizer core 2.
[0039] The upper surface of the bracket 3 is concave to form a plug-in cavity 301. The bottom end of the atomizer core 2 is inserted downward toward the plug-in cavity 301 until it abuts against the bottom of the cavity. The bottom end of the atomizer core 2 is clamped between the side wall of the upper part of the air flow hole 300 and the inner wall of the plug-in cavity 301. The outer wall of the atomizer core 2 is provided with an annular groove, and a sealing ring is installed in the groove. The sealing ring is squeezed between the atomizer core 2 and the plug-in cavity 301 to enhance the sealing performance there. The side wall of the upper part of the air flow hole 300 extends higher than the bottom surface of the plug-in cavity 301, and is inserted into the atomizer core 2 and docked with the atomization channel therein, which is conducive to the entry of external air into the atomizer core 2.
[0040] In some embodiments, the atomizer core 2 is provided with an oil-conducting cotton 200, and the lower portion of the oil-conducting cotton 200 extends to the bottom end of the atomizer core 2 to connect with the upper end of the reflux groove 5. The residual liquid in the condensation chamber 4 flows along the reflux groove 5 toward the atomizer core 2, and is absorbed by the oil-conducting cotton 200 in the atomizer core 2 when reaching the port at the upper end of the reflux groove 5.
[0041] In some embodiments, each of the extension blocks 303 is disposed on the outer bottom surface of the plug-in cavity 301 and is close to the edge of the air flow hole 300. This solution makes adjustments to the original structure of the bracket 3, directly using the outer bottom surface of the plug-in cavity 301 to partially extend downward to form the extension block 303. At the same time, the extension block 303 is close to the air flow hole 300. Under the premise of not affecting the structure of the condensation cavity 4, the extension block 303 and the reflux groove 5 are arranged by occupying part of the cavity space, which is not only conducive to preventing the reflux groove 5 from being too long, but also makes the solution more versatile.
[0042] In some embodiments, the outer bottom surface of the plug-in cavity 301 is provided with two plug-in posts 302, and the two plug-in posts 302 correspond to the two bosses 7 in the air, and each plug-in post 302 is provided with a socket, and the electrode nail 6 is inserted into the corresponding socket via the boss 7. There are two electrode nails 6 of the cigarette cartridge 1, which are inserted upward into the socket of the corresponding plug-in post 302 via a boss 7, and the bottom end of the plug-in post 302 is opposite to the boss 7 in the air, that is, there is a space between the two, and the connection between the heating wire of the atomizer core 2 and the electrode nail 6 is achieved through the space.
[0043] An electronic atomization device is provided, comprising a host, on which is mounted a cigarette cartridge 1 as described in any of the preceding items.
[0044] The improved cigarette cartridge 1 is provided with a reflux groove 5 on the bracket 3. The user's suction action generates a negative pressure force, and the residual liquid in the condensation chamber 4 is drained back to the atomization core 2 through the reflux groove 5 for re-atomization, thereby effectively reducing the amount of residual liquid in the chamber and reducing the phenomenon of residual liquid leaking through the air inlet.
[0045] The above description is only the preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications, combinations and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the scope of the claims of the utility model.
