In order to make those skilled in the art better understand and implement the embodiments of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 shows a schematic cross-sectional view of a liquid accumulator in an embodiment of the present invention, and Fig. 2 shows a cross-sectional schematic view of another liquid accumulator in an embodiment of the present invention. In Figs. 1 and 2, the accumulator The liquid container is a liquid storage cavity, that is, the basic shape of the liquid storage container is a column, and the space for the oil storage is also a cylindrical cavity. Those skilled in the art can use other shapes of liquid storage containers according to actual needs. The shape does not constitute any limitation to the scope of protection of the present invention.

For ease of understanding, the following descriptions are given by taking the liquid reservoir as an example of the shape of the cylindrical cavity. Moreover, the arrows in Fig. 1 and Fig. 2 indicate the flow direction of the liquid in the accumulator. The difference between Fig. 1 and Fig. 2 is only the height of the liquid level in the accumulator. Some of the liquid in the reservoir has flowed out.

Referring to FIG. 1 and FIG. 2 , the above-mentioned liquid accumulator may include: a liquid storage body 14 , a liquid outlet 15 and a sealing member 12 . In addition, the above-mentioned liquid storage body 14 can be used to store the liquid 13, and the above-mentioned liquid storage main body 14 can be provided with the above-mentioned liquid outlet 15 at one end, and at the same time, the other end corresponding to the above-mentioned one end can be provided with an opening 11. In other words, The inside of the above-mentioned accumulator can be in contact with the atmosphere outside the accumulator through the above-mentioned opening 11 . As shown in FIG. 1 , the end A of the liquid storage body 14 is provided with an opening 11 , the opening 11 is in direct contact with the external environment where the liquid reservoir is located, and the end B is provided with a liquid outlet 15 .

The above-mentioned liquid outlet 15 can be used to derive the above-mentioned liquid 13 in the above-mentioned liquid storage main body 14, that is, the liquid 13 can flow out through the liquid outlet 15, and as mentioned above, the liquid outlet 15 can be arranged on the above-mentioned liquid storage main body 14. One end, that is, one end of the cylindrical cavity, is installed with the relevant components of the liquid outlet 15 .

In a specific implementation, the liquid outlet 15 may have small holes, and the diameter of the holes may not exceed 10 mm. In addition, the hole may be a single hole, or a plurality of holes may be arranged, so that the speed of the liquid outlet 15 can be improved. In an embodiment of the present invention, the total area of the holes on the liquid outlet 15 does not exceed the area of a circle with a diameter of 10 mm, so that the liquid 13 can be prevented from flowing out too fast.

It should be noted that the embodiments of the present invention do not impose any restrictions on the materials used for the liquid storage cavity components and the liquid outlet 15. Specifically, the liquid storage cavity components and the liquid outlet 15 can use various materials. , such as plastics, metals, ceramics, glass, rubber, wood, synthetic fibers or polymer materials.

The sealing member 12 may be provided between the other end of the liquid storage body 14 and the liquid surface of the liquid 13 . Specifically, when the accumulator is filled with liquid, which can also be referred to as the initial stage, the sealing member 12 can be in contact with the other end of the liquid accumulator body 14 and the liquid surface of the liquid 13, respectively, and in the liquid 13 During the process of changing the liquid level, the sealing member 12 can always keep in contact with the liquid level of the above-mentioned liquid 13 . In order to improve the sealing performance, in an embodiment of the present invention, the sealing member 12 may keep in contact with the liquid surface of the liquid 13 in the liquid storage body 14 during the process of changing the liquid level. It should be noted that, no matter it is the initial stage, that is, the stage when the liquid 13 is not used, or the stage when the liquid level of the liquid 13 drops due to being used, the sealing member 12 and the liquid 13 are not subjected to additional external force, but It is in equilibrium under the action of atmospheric pressure.

To sum up, the liquid storage device in the embodiment of the present invention is filled with liquid such as e-liquid in the liquid storage space formed by the liquid storage body, and one end is closed by the liquid outlet member with holes, and only the holes are reserved as the liquid outlet. For example, a liquid outlet is provided at one end of the liquid reservoir, and the other end of the liquid reservoir is opened and filled with sealing parts to keep in contact with the liquid and seal the liquid, so it can reduce the leakage of the liquid reservoir. Probability, even a leak from the reservoir can be avoided.

In order to always keep in contact with the liquid surface of the liquid 13 in the liquid storage main body 14 or even surface contact during the process of changing the liquid level of the liquid 13, in a specific implementation, the sealing member 12 can follow the liquid level of the liquid 13. The liquid level descends and moves in the direction in which the liquid level descends. In other words, during the continuous consumption of the liquid 13, the volume of the liquid 13 is continuously reduced, and the sealing member 12 can keep in contact with the liquid 13 as the liquid level drops, and maintain the sealing effect on the liquid 13. Moreover, during the use of the product with the above-mentioned accumulator installed, the rolling and inversion of the product itself will not cause the sealing member 12 to disengage from the sealing contact position with the liquid 13 .

In order to simplify the structure of the liquid accumulator, in an embodiment of the present invention, a follow-up sealing body may be used as the above-mentioned sealing member 12 . Of course, those skilled in the art can also select other components as the above-mentioned sealing component 12 according to actual needs, as long as the selected components can descend as the liquid level drops, and can always keep in contact with the liquid level. For ease of understanding, the following description will be made by taking the sealing member 12 as an example of a follower sealing body as an example.

In a specific implementation, the above-mentioned sealing member 12, or the follow-up sealing body may be a transparent to translucent jelly, which has the properties of shock resistance, evaporation resistance, and strong follow-up sealing. The above-mentioned sealing member 12 can also be filled into any space, and has a relatively fixed shape, which will not flow or disperse randomly in the space, and can maintain a cohesive state. When the volume of the liquid 13 changes, the sealing member 12 can keep in contact with the liquid level of the liquid 13, and follow the change of the liquid level and move its position to keep the sealing state of the liquid 13 all the time, and is suitable for the cavity diameter of the liquid reservoir. Storage space within 1mm to 30mm.

In a specific implementation, the sealing member 12 can maintain the fluidity and continuous output performance under the condition that the closed liquid 13 is kept in contact with the atmospheric pressure, and the internal gas of the liquid reservoir will not occur after the liquid 13 is consumed in the closed space. Negative pressure is generated, causing the problem that the liquid 13 cannot flow out. At the same time, in the low air pressure state, since the position of the sealing member 12 can be adjusted by itself to adapt to the changes in volume and pressure, in the low air pressure transportation, there will be no problem of flatulence and liquid leakage.

Moreover, it can be understood that the sealing member 12 is a substance with relatively stable physical properties and chemical properties. In an embodiment of the present invention, synthetic grease may be used as the sealing member 12, for example, one or more of ester-based substances, liquid-based substances, and organosilicon synthetic compounds may be used. Specifically, it can be selected from one or more of lithium-based esters, silicon esters, and fluorosilicone esters. Among them, lithium-based ester is a composite ester containing extremely siloxane. It can be produced by using synthetic oil as base oil and silica as thickener. In other words, lithium-based ester is thickened with glass powder. synthetic oil. During the process of contacting with the liquid 13, the sealing member 12 can adjust its own density and viscosity accordingly according to the properties of the liquid, such as the density and viscosity of the smoke liquid. In addition, the sealing member 12 needs to ensure that its material and the components in the liquid 13 do not chemically react, and do not dissolve or penetrate each other, and can keep the interface with the liquid 13 clear and flat.

In order to save costs, in an embodiment of the present invention, the sealing member 12 with good followability can be selected. The residual consumption of the pipe wall does not exceed 10% of its own total volume.

According to its own volume, the sealing member 12 can generate different surface tensions, thereby generating different fluidities. In order to adjust the surface tension of the sealing member 12 to meet different volume application requirements, in an embodiment of the present invention, the above-mentioned The liquid accumulator may further include: a tension limiting member (not shown), and the tension limiting member may be specifically arranged in the sealing member 12 .

In a specific implementation, the above-mentioned tension limiting member can be arranged at a central position in the above-mentioned sealing member 12 , that is, the distance between the tension-limiting member and each outer surface of the sealing member 12 is basically the same, so that the surface tension of the sealing member 12 can be improved. Therefore, when the cross-sectional area of the liquid storage body 14 is large and the liquid storage container is placed obliquely or inverted, the probability of the sealing member 12 flowing out from the opening 11 can be reduced.

It should be noted that, the above-mentioned tension limiting member may have various styles. For example, the above-mentioned tension limiting member may be a solid float or a placeholder. For another example, the above-mentioned tension limiting member may be a mixture of a placeholder and a solid float. The embodiment of the present invention does not limit the number of the tension limiting components placed.

Also, when the above-mentioned tension limiting member is a solid float, the solid float can be completely submerged in the sealing member 12 . The specification of the solid-state float is positively related to the specification of the above-mentioned sealing member 12 . Specifically, the definition of the volume of the solid-state float can be determined according to the volume of the follow-up sealing body in principle. The distance between the solid state float and the outer boundary of the sealing member 12 is not less than 50% of the distance between the center position of the sealing member 12 and the outer boundary of the sealing member 12 . If the sealing member 12 has a regular symmetrical shape, the distance between the center position of the sealing member 12 and the outer boundary of the sealing member 12 is the radius r of the sealing member 12, so the distance between the solid-state float and the outer boundary of the sealing member 12 is not less than half of the radius r of the above-mentioned sealing member. In an embodiment of the present invention, if the sealing member 12 is cylindrical, the distance between the solid float and the outer boundary of the sealing member 12 is about 1 mm˜3 mm. Alternatively, according to the change in the diameter of the liquid column of the stored liquid 13 , a placeholder may be placed in the sealing member 12 to limit the surface tension of the liquid 13 , and the placeholder may specifically be a component such as a plastic ball or a column.

It should be noted that, as people pay more and more attention to health, people realize that traditional cigarettes have certain harm to health, and therefore, products called "electronic cigarettes" have been produced. Electronic cigarettes are used as a substitute for traditional cigarettes and are essentially a liquid smoke atomizer.

It should be noted that the liquid guide buffer member 17 can be disposed outside the liquid outlet 15 , and the liquid guide buffer member 17 has porous properties, has the ability to absorb the liquid 13 , and can also have a gravitational effect on the liquid 13 . Regarding the material, cotton, fibrous material, sponge-like material, porous ceramic, metal sintered porous material, or low-foaming polymer material can be used for the liquid-conducting buffer member 17 .
