Description

Atomizer core with self-circulating adjustment of oil intake

This application claims the priority of the Chinese patent application with application number 202021618948.0 filed on August 6, 2020, the entire contents of which are incorporated herein by reference.

technical field

The present application relates to an atomizing core that can adjust the oil intake, in particular to an atomizing core that can achieve pressure balance through self-circulation in the atomizer, thereby adjusting the oil intake.

Background technique

Currently used electronic cigarettes, also known as aerosol generating devices, the most important component is the atomizer. The atomizer is provided with an oil storage tank for storing electronic cigarette oil, and an atomizing core is set in the oil storage tank. As shown in FIG. 1 , it is an atomizer in the prior art, which has a closed casing 2 and a base 7 , and the casing 2 and the base 7 are assembled to form a closed oil storage bin 4 . The atomizing core 5 is installed on the base 7, and the bottom of the atomizing core 5 is provided with an air inlet channel, and the air inlet channel is connected to the outside atmosphere. A smoking channel 3 is connected to the top of the atomizing core 5, and the smoking channel 3 is connected to the suction nozzle 1 for inhaling smoke, and the suction nozzle 1 is also connected to the atmosphere in a non-smoking state. The side wall of the atomizing core 5 is provided with an oil inlet hole 6, and the oil inlet hole 6 is located in the atomizer oil storage bin 4, and is generally required to be located below the liquid level of the e-liquid in the oil storage bin 4, so that the e-liquid can pass through. The oil inlet hole 6 enters the inside of the atomizing core 5 . The inside of the atomizing core 5 is provided with an oil guide body and a heating wire, and the surface of the heating wire is closely arranged on the oil guide body. On the surface, the heating wire heats up to atomize the e-liquid on the surface, and the generated aerosol is sucked out and taken away.

Therefore, the e-liquid is stored in the sealed oil storage tank, and is connected to the atmosphere through the oil inlet hole 6 and the oil-conducting medium. If the pressure in the oil storage tank 4 is the same as the atmospheric pressure, the e-liquid will flow from the guide under the action of its own gravity. The oil medium exudates and aggregates into droplets, and then leaks from the intake passage or the smoking air passage. This phenomenon is called "oil leakage" and is a taboo for electronic cigarette products. In order to avoid oil leakage, it is generally necessary to maintain the pressure of the oil storage tank 4 slightly lower than the external atmospheric pressure, and then use the resistance of the oil guiding medium to achieve a static balance between the atmospheric pressure and the pressure in the oil storage tank 4 and the resistance of the oil guiding medium .

The above state is in a static state, that is, a non-smoking state, but the role of electronic cigarettes is to smoke, and dynamic occurs during smoking, breaking the static balance. The specific process is:

(1) The heating wire works to generate heat, and the smoke oil on the surface of the heating wire is atomized into aerosol and sucked out to form an air flow;

(2) When the airflow is sucked out, a negative pressure is generated in the atomizing core 5, which breaks the static equilibrium state;

(3) Under the action of the negative pressure of the atomizing core 5, the oil guide body supplements the e-liquid to the surface of the heating wire;

(4) Also under the action of negative pressure, the e-liquid is guided by the oil storage bin 4 through the oil inlet hole 6 to supplement the e-liquid to the oil body;

(5) The e-liquid in the oil storage bin 4 is gradually reduced. Since the oil storage bin 4 is a sealed bin, the pressure of the sealed oil storage bin 4 is gradually reduced, forming a larger negative pressure;

If you continue to smoke at this time, the negative pressure of the oil storage tank may gradually increase, but the airflow of the smoking does not change much, and the negative pressure resistance increases, which makes the supply of e-liquid difficult, and the e-liquid in the oil-conducting medium in the atomizing core After it is exhausted, it will produce dry burning, which not only affects the taste, but also damages the atomizing core. Therefore, the smoking action must be controlled to be completed within a certain period of time, so that the atomizing core can be smoked again after the oil supply is restored.

If you stop smoking, the next process is:

(1) The negative pressure in the atomizing core 5 disappears and the atmospheric pressure is restored, but the oil storage bin 4 is still in a negative pressure state. At this time, the e-liquid is adsorbed in the oil guide body under the action of negative pressure, and even retracts to the oil storage. In warehouse 4, open the channel for the return air;

(2) After a period of time, due to the pressure difference between the negative pressure of the oil storage tank 4 and the atmospheric pressure in the atomizing core, the outside atmosphere enters the oil storage tank 4 through the oil guide body and the oil inlet hole 6, and then the oil is stored. The pressure of warehouse 4 begins to rise, and gradually reaches static equilibrium again;

(3) Since the pressure has reached a balance, the e-liquid will enter the atomizing core 5 again, and then the smoking action can be performed again.

According to the above description, it can be concluded that the process of smoking electronic cigarettes is a cyclic process of smoking - stopping smoking and supplying oil - smoking again, and it is impossible to be in a smoking state for a long time.

Due to the individual differences of smokers, smoking habits are also different. Some people like long inhalation and long pause, others like long inhalation and short pause, and some like short inhalation and long pause, short inhalation and short pause, etc., which are all different habits. And smoking habits are constantly changing. Therefore, it is necessary to fully consider the above problems when designing electronic cigarettes, but it is difficult for the same electronic cigarette product in the prior art to satisfy the above four different smoking habits at the same time. If the designed e-cigarette smoking time is 3 seconds, the e-liquid in the atomizing core will be consumed within 3 seconds. The e-liquid will not be replenished when you continue to smoke, and the oil will only be added when you stop smoking. For smoking, it is required to reach 5 seconds. people are not suitable.

In view of the above reasons, the following analysis is made. The so-called smoking time and withdrawal time are affected by the amount of e-liquid in the atomizing core and the supply of e-liquid. After the e-liquid in the atomizing core is consumed, it is necessary to stop the suction and supply of oil. If a sufficient supply of e-liquid can always be maintained, long-term smoking can be achieved without the need to stop the suction and supply process. Whether the oil supply continues is directly related to the pressure of the oil storage tank. As mentioned above, when the pressure of the oil storage tank decreases after a long time of inhalation, the oil supply will be hindered, while the pressure of the inhalation airflow is relatively stable. When the pressure of the warehouse is restored in time, the oil supply status can be changed, and continuous oil supply can be realized, thereby achieving the effect of long-term smoking.

To sum up, as long as the pressure of the oil storage tank is replenished in time, the effect of long-term smoking can be achieved. In the prior art, the closed atomizer itself cannot realize supplementary pressure, because the atomizer core has only one set of oil inlet holes connected to the outside world, and the pressure cannot be supplemented at the same time when supplying oil, and the oil cannot be supplied simultaneously when the pressure is supplemented. Some people have developed a way to achieve pressure balance by opening the outside of the oil storage tank to relieve pressure. This pressure relief structure is to directly connect the oil storage tank to the atmosphere, which can achieve the purpose of supplementing the pressure, but when the atmospheric pressure is reached, the smoke oil It will seep out from the oil guide body under the action of gravity, resulting in oil leakage, and it is difficult to control the static pressure balance by opening the pressure relief method.

In the non-smoking state, the internal pressure of the electronic cigarette will be balanced and there will be no oil leakage. However, during the transportation and carrying process, there may be a sudden increase or decrease in the pressure. When the external pressure decreases, such as when taking an airplane, due to the external pressure The pressure is reduced, the static balance is broken, and it is easy to cause oil leakage. When the external pressure rises, due to the high external pressure, the e-liquid will retract and cause fuel supply difficulties.

For this reason, the designer of the present application has developed an atomizing core that adjusts the oil intake through self-circulation, which can automatically adjust the pressure of the oil storage tank through the pressure difference generated by its own air flow during smoking, so that the pressure of the oil storage tank is always in a Dynamically balanced state, adjust the supply of e-liquid.

Embodiments of the present invention

The technical solutions of the present application will be clearly and completely described below with reference to the embodiments of the present application and the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

Example 1:

As shown in Figures 2 and 3, this embodiment is an atomizing core that can adjust the oil intake through self-circulation. The atomizing core 5 of this embodiment includes a casing 12, an oil-conducting medium 11 and a heating element 10, wherein the atomizing core casing 12 is a complete cylindrical structure, the bottom is provided with an intake air passage to communicate with the outside atmosphere, and the top is provided with smoking gas The duct communicates with the outside atmosphere, and the lower part of the casing 12 is provided with four evenly distributed oil inlet holes 6 , and the oil inlet holes 6 are evenly distributed at the same axial position of the atomizing core casing 12 . The inner side of the housing 12 of the atomizing core is the oil-conducting medium 11 that covers the inner surface of the housing as a whole, here is the oil-conducting cotton fiber cylinder. The inner side of the oil-conducting medium 11 is closely arranged with a heating element 10, which may be a heating wire or a heating net, and is also arranged on the inner surface of the oil-conducting medium 10 in a cylindrical shape.

If configured according to the above structure, the structure is not substantially different from the prior art atomizing core structure. Therefore, in order to reflect the difference and advancement of this technical solution, the axial length of the atomizing core shell 12 is extended, even to the extent of replacing the smoking airway, and the upper section can be directly connected to the suction nozzle. That is to say, the axial direction of the atomizing core is longer, and when it is used vertically on the atomizer, the height is higher than that of the ordinary atomizing core. As shown in FIG. 2 , the axial length of the oil-conducting medium 11 disposed inside the super-high atomizing core housing 12 is equal to or slightly smaller than the length of the housing 12 , and covers the inner surface of the super-high atomizing core housing 12 from the inside.

The heating element 10 is not arranged according to the super high structure, but is only arranged at the lower part of the atomizing core, that is, at the height position of the oil inlet hole 6 of the side wall of the atomizing core shell 12, but is higher than the oil inlet hole 6. The elevation occupied should be larger, so that the oil inlet hole 6 can be covered, and the e-liquid entering from the oil inlet hole 6 can be atomized in time.

The purpose of setting the ultra-high atomizing core shell is to open the air return hole 9 at the position close to the top of the ultra-high atomizing core shell 12. The number of the air return hole 9 is also arranged in four axial directions, and the radial positions correspond to The lower oil inlet hole 6, and the diameter of these return air holes is smaller than that of the oil inlet hole.

In this way, an oil inlet hole 6 and an air return hole 9 are respectively opened on the side wall of the super high atomizing core shell 12, wherein the oil inlet hole 6 is located at the lower part and the air return hole 9 is located at the upper part. The inner casing of the atomizing core 12 is provided with an integral cylinder of the oil-conducting medium 11, the lower part of the oil-guiding medium covers the oil inlet hole 6, the upper part covers the air return hole 9, and only the heating element 10 is arranged in the cylinder of the oil-guiding medium 11 at the lower part of the atomizing core , the upper part where the air return hole 9 is located is not provided with a heating element.

When the atomizing core of this structure is used in the atomizer, the bottom is connected with the air intake passage, the top is connected with the smoking air passage, and the outer side is sealed with the oil storage tank, leaving only the oil inlet hole 6 and the return port for the oil guiding medium 11. The air hole 9 is in a communication state with the oil storage tank.

As shown in FIG. 1 , when the atomizing core of this embodiment is used in the oil storage tank of the atomizer, the bottom of the atomizing core is set at the bottom of the atomizer, and the oil inlet hole 6 is located below the liquid level of the e-liquid. The air hole 9 can be located below the liquid level or above the liquid level. During the specific production, the air return hole 9 is set as far as possible at the upper part of the atomizing core, so as to open the height difference with the oil inlet hole 6 . At this time, the pressure at the oil inlet hole 6 is greater than the pressure at the air return hole 9 . When there is e-liquid entering the atomizing core at the oil inlet hole 6, if the pressure in the atomizing core is kept stable, the air return hole will return air to supplement the pressure of the oil storage tank, and reach a state of pressure balance with the pressure of the oil storage tank. The air return from the air hole is automatically formed because the pressure of the oil storage tank drops when the oil is supplied to the oil inlet hole, realizing self-circulation adjustment.

As shown in FIG. 7 , when the atomizing core of this embodiment is used for atomizing smoking, the airflow of smoking is generally stable, so the negative air pressure P inside the atomizing core is also relatively stable. The height difference between the air return holes 9 exists, the pressure P2 at the oil inlet hole 6 in the oil storage bin will be greater than the pressure P1 at the return air hole 9 of the oil storage bin, and the resistance of P1 plus the oil guiding medium 11 and P will be in a temporary balance State, will not return air or oil. The heating element 10 continues to generate heat to atomize the e-liquid, and when the e-liquid of the oil-conducting medium 11 is exhausted, the oil inlet hole 6 starts to supply oil. The pressure P1 of the oil tank also decreases accordingly, and gradually loses balance with the negative air pressure P in the atomizing core. When the air pressure P inside the atomizing core at the air return hole 9 is greater than the pressure in the oil storage tank 4, the phenomenon of airflow backflow will be formed, and part of the air flow will return to the oil storage tank to supplement the pressure of the oil storage tank, so as to realize continuous oil supply .

The oil guiding medium 11 provided in this embodiment is integrally arranged through the atomizing core. At the position of the upper air return hole 9, since no heating element is provided, as the oil guiding medium, a support frame 8 needs to be installed, and the support frame 8 is provided with a corresponding The opening at the position of the air return hole is used to ensure that the shape of the oil-conducting medium 11 here does not change. The purpose of arranging a through oil-conducting medium is also to increase the storage space of e-liquid in the atomizing core, prolong the storage capacity of e-liquid on the body, and prolong the smoking time. The reason why the heating element is not provided at the position of the air return hole 9 is to avoid the atomization here causing the oil to enter the air return hole 9 and lose the air return function.

Example 2:

As shown in FIG. 4 and FIG. 5 , this embodiment is an atomizing core that can adjust the oil intake through self-circulation. The atomizing core of this embodiment is divided into two sections, the lower section is the atomizing core body section 16, the upper section is the atomizing core gas return section 14, and the body section 16 and the gas return section 14 are sealed but connected. The casing of the body section is provided with an oil inlet hole 6 , the inner side of the casing of the body section is provided with a first oil guiding medium 15 , and the inner side of the first oil guiding medium 15 is provided with a heating element 10 . The casing of the air return section is provided with an air return hole 9 , and a second oil guide medium 13 is arranged inside the casing of the air return section 14 , and a support body is arranged inside the second oil guide medium 13 to support and maintain the shape of the second oil guide medium 13 stably, and return The gas section is a non-atomization area without a heating element.

As shown in FIG. 6, it is a schematic cross-sectional structure diagram of the atomizing core of this embodiment used on the atomizer, wherein the overall height of the atomizing core is equal to the inner height of the atomizer shell 2, which is just inside the oil storage tank. The upper end of the air return section 14 of the atomizing core is docked with the smoking air duct 3, and can also be docked with the suction nozzle. At this time, the atomizing core is enclosed in the oil storage bin, and the smoke enters the smoke oil through the oil inlet hole 6 when smoking, and at the same time, the oil smoke enters the oil smoke through the air return hole 9. Since the function of the air return hole 9 is only used for air return, and the return air is used to balance the pressure of the oil storage tank, the aperture should be smaller than that of the oil inlet hole 6 to avoid leakage of e-liquid from the air return hole 9 . At the same time, since the pressure at the air return hole 9 is relatively small, in order to make the return air enter the oil tank more easily, the porosity of the second oil-conducting medium 13 can also be larger than that of the first oil-conducting medium 15 to improve the permeability. .

During the smoking action, the smoking air flows axially through the atomizing core, and the e-liquid enters the atomizing core from the oil storage tank from the oil inlet hole 6 to be atomized. The pressure at the location is further reduced. When the pressure is lower than the negative pressure of the airflow, part of the aerosol separated from the airflow will be returned to the oil storage tank through the return air hole 9. Increase the pressure of the oil storage tank and adjust the supply of e-liquid.

Example 3:

As shown in FIG. 8 , this embodiment is an improvement based on the structure of the atomizing core of the traditional horizontal heating device. Pull up the atomizing core of the traditional horizontal heating device, and also open the air return hole 6 at the position near the top of the upper part of the atomizing core. Since in this structure, the horizontal oil guiding medium 18 is arranged in the helix of the heating body 10, and the internal space of the overall atomizing core is relatively large, so it is not suitable to set the oil guiding medium on the inner surface of the atomizing core at the air return hole 9. Therefore, only the filling oil guiding medium 17 can be set in the air return hole 9, and the filling oil guiding medium 17 is filled into the air returning hole to block the entry of e-liquid and balance the pressure inside and outside the atomizing core.

The above description is based on the description of the preferred embodiment. Of course, in addition to the above-mentioned embodiment, those skilled in the art may develop other structures and methods according to the basic idea of the application, but on the basis of not departing from the idea of the application The transformation should be within the scope of protection of this application.
