Description

RELATED APPLICATION

[0001] The present application claims the benefit of priority to a Chinese Patent Application No. 2023211859210, filed on May 17, 2023, and entitled "Atomization Device and Electronic Atomizing Equipment," the entire content of which is incorporated herein by reference.TECHNICAL FIELD

[0002] The present application relates to the field of atomization devices, and in particular, to a atomization device and an electronic atomizing equipment.BACKGROUND

[0003] The atomization device is a crucial component of an electronic atomizing equipment. During use, the vapor generated by the atomization device is produced by heating the e-liquid on the internal oil-absorbent cotton with a heating wire, causing the e-liquid to evaporate.

[0004] Unused atomization devices generally feature an isolation treatment between the atomization core assembly and the inner chamber of the oil cup. This precaution prevents e-liquid from leaking at the atomization core during transportation. When the user begins to use the atomization device, they open the isolation mechanism to allow the atomization core assembly to come into contact with the e-liquid in the oil cup's inner chamber, enabling the oil supply. However, after the isolation between the atomization core assembly and the e-liquid in the oil cup's inner chamber is removed, it takes some time for the e-liquid to saturate the oil-absorbent cotton in the atomization core assembly. If the atomization device is used during this period, the insufficient saturation of the oil-absorbent cotton with the e-liquid may lead to abnormal conditions such as a burnt taste, affecting the user's experience.SUMMARY

[0012] In some embodiments, an inner wall of the second open end of the oil cup is provided with a shoulder structure, where the shoulder structure is engaged with the second end of the sealing sleeve when the oil core separation section is at the second active position, and the end of the pull rod away from the sealing sleeve continues to move towards outside of the internal cavity of the oil cup, and the pull rod disconnects from the second end of the sealing sleeve.

[0013] In some embodiments, the sealing sleeve includes a first sealing sub-sleeve, where a first end of the first sealing sub-sleeve is coaxially and movably connected to the second end of the atomization core section, and the first end of the first sealing sub-sleeve is fitted over the second end of the atomization core section.

[0031] Refer to Figures 1 to 4. Figure 1 illustrates a schematic structural diagram of a atomization device provided in an embodiment of the present application. Figure 2 illustrates a cross-sectional structural schematic diagram of the atomization device in an oil core separation state, as provided in an embodiment of the present application.

Figure 4 illustrates a schematic structural diagram of the sealing sleeve section of the atomization device, as provided in an embodiment of the present application.

[0032] In one embodiment of the present application, a atomization device is provided, including: an oil cup 100, an atomization core section 200, and an oil core separation section 300. The oil cup 100 is provided with an internal cavity. A first end of the atomization core section 200 (the lower end of the atomization core section as shown) is mounted on a first open end of the oil cup 100, the bottom opening of the oil cup 100 as shown. A second end of the atomization core section 200 extends into the internal cavity of the oil cup 100, with an oil inlet 240 provided on the outer wall of the atomization core section 200. The oil core separation section 300 is movably connected between the atomization core section 200 and the oil cup 100, with a first end of the oil core separation section 300 (the lower end of the oil core separation section as shown) positioned within the internal cavity of the oil cup 100, and a second end of the oil core separation section 300 (the upper end of the oil core separation section as shown) at least partially extending out of a second open end of the oil cup 100.

[0033] During the process of the oil core separation section 300 moving from a first active position to a second active position, the volume of the internal cavity of the oil cup 100 decreases, and the pressure within the internal cavity of the oil cup 100 increases. The first active position and the second active position are illustrated as follows.

[0034] The first active position of the oil core separation section 300 is configured such that the first end of the oil core separation section 300 (the lower end of the oil core separation section as shown) covers the atomization core section 200 and isolates the internal cavity of the oil cup 100 from the oil inlet 240, preventing the e-liquid stored in the internal cavity of the oil cup 100 from contacting the oil inlet 240 of the atomization core section 200. The second active position of the oil core separation section 300 is configured such that the first end of the oil core separation section 300 moves to expose the oil inlet 240 of the atomization core section 200, allowing the e-liquid stored in the internal cavity of the oil cup 100 to contact the oil inlet 240 of the atomization core section 200. This configuration enables the oil core separation section 300 to expose the oil inlet 240 of the atomization core section 200, allowing the e-liquid to begin to saturate the oil-absorbent cotton through the oil inlet 240 of the atomization core section 200.

[0035] The oil core separation section 300, regardless of whether it is in the first active position or the second active position, has one end that is movably connected to the second open end of the oil cup 100 inside the oil cup 100.

[0036] It should be noted that the second end of the oil core separation section 300 generally needs to extend outside the oil cup 100, facilitating the user to pull the second end of the oil core separation section 300 to move the oil core separation section 300, thereby removing the isolation between the e-liquid in the internal cavity of the oil cup 100 and the atomization core section 200.

[0037] In this embodiment, in the initial state, the oil core separation section 300 isolates the e-liquid from the atomization core section 200 within the internal cavity of the oil cup 100. Meanwhile, the connection structure between the oil cup 100, the atomization core section 200, and the oil core separation section 300 ensures that the internal cavity of the oil cup 100 is a sealed space, keeping the e-liquid in the internal cavity of the oil cup 100 completely enclosed, effectively preventing e-liquid leakage. During the process of removing the isolation state between the atomization core section 200 and the e-liquid, the space of the internal cavity of the oil cup 100 gradually decreases, which increases the pressure within the internal cavity of the oil cup 100, thereby forcing the e-liquid into the oil-absorbent cotton of the atomization core section 200. It significantly increases the saturation speed of the atomization core section 200 and achieves the desired saturation effect of the atomization core section 200.

[0038] In one embodiment of the present application, the oil core separation section 300 is provided with a connecting segment, where the movement distance of the connecting segment of the oil core separation section 300 within the second open end of the oil cup 100 is equal to the movement distance of the oil core separation section 300 between the first active position and the second active position. The connecting segment of the oil core separation section 300 is configured as the area of the oil core separation section 300 that is movably connected with the second open end of the oil cup 100.

[0039] Regarding the structure of the second open end of the oil cup 100, as can be seen from the illustration, the second open end of the oil cup 100 is provided with a sealing connection segment that extends into the internal cavity of the oil cup 100. In other words, in this embodiment, the connecting segment of the oil core separation section 300 can fully extend into this sealing connection segment within the oil cup 100.

[0040] In one embodiment of the present application, the cross-sectional area of the connecting segment of the oil core separation section 300 is smaller than the cross-sectional area of the first end of the oil core separation section 300 (the lower end of the oil core separation section 300 as shown). Due to the difference in cross-sectional area between the connecting segment of the oil core separation section 300 and the first end of the atomization core section 200, the volume of the internal cavity of the oil cup 100 changes during the movement of the oil core separation section 300 between the first active position and the second active position. In some embodiments, during the process in which the oil core separation section 300 moves from the first active position to the second active position, the connecting segment of the oil core separation section 300 gradually extends into the sealing connection segment 120 of the oil cup 100, thereby gradually decreasing the volume of the internal cavity of the oil cup 100, which correspondingly increases the pressure, facilitating the e-liquid being pressed into the oil-absorbent cotton of the atomization core section 200.

[0041] In some embodiments, during the transition of the oil core separation section 300 from an oil core isolation state to an oil core connection state, the reduced volume V 1 of the internal cavity of the oil cup 100 is: V 1 = (A 1 - A 2 ) * H, where A 1 is the cross-sectional area of the first end of the oil core separation section 300, A 2 is the cross-sectional area of the connecting segment of the oil core separation section 300, and H is the movement distance of the oil core separation section 300.

[0042] It can be seen that the reduced volume of the internal cavity of the oil cup 100 is related to the difference in cross-sectional area between the connecting segment of the oil core separation section 300 and the first end of the oil core separation section 300 (the lower end of the oil core separation section 300 as shown). The reduced volume of the internal cavity of the oil cup 100 is also related to the movement distance of the connecting segment of the oil core separation section 300 within the sealing connection segment 120 of the oil cup 100.

[0043] In one embodiment of the present application, after the pulling of the oil core separation section 300 is completed, when the volume of e-liquid entering the oil-absorbent cotton of the atomization core section reaches 30% to 100% of the volume of the oil-absorbent cotton of the atomization core section, a good atomization effect can be achieved. When the volume of e-liquid entering the oil-absorbent cotton of the atomization core section is less than 30% of the volume of the oil-absorbent cotton of the atomization core section, insufficient e-liquid supply may cause a burnt taste, affecting the user experience. When the volume of e-liquid entering the oil-absorbent cotton of the atomization core section reaches 100% of the volume of the oil-absorbent cotton of the atomization core section, e-liquid can no longer enter the atomization core and begins to leak from the atomization core.

[0044] In one embodiment of the present application, the oil core separation section 300 includes a sealing sleeve 310 and a pull rod 320.

[0045] A first end of the sealing sleeve 310 (the lower end of the sealing sleeve 310 as shown) is coaxially and movably connected to the second end of the atomization core section 200 (the upper end of the atomization core section 200 as shown). The first end of the sealing sleeve 310 (the lower end of the sealing sleeve 310 as shown) is fitted over the second end of the atomization core section 200 (the upper end of the atomization core section 200 as shown). A second end of the sealing sleeve 310 (the upper end of the sealing sleeve 310 as shown) is coaxially and movably connected to the second open end of the oil cup 100 (the upper end of the oil cup 100 as shown). The pull rod 320 has one end that is close to the sealing sleeve 310 and is connected to the first end of the sealing sleeve 310, while the opposite end of the pull rod 320 away from the sealing sleeve 310 extends out of the internal cavity of the oil cup 100.

[0046] During use, by pulling the pull rod 320 in the direction away from the oil cup 100, the sealing sleeve 310 is driven to move towards the second open end of the oil cup 100, thereby removing the isolation between the e-liquid in the internal cavity of the oil cup 100 and the atomization core section 200.

[0047] Furthermore, a shoulder structure 110 is provided on the inner wall of the second open end of the oil cup 100. When the oil core separation section 300 is in its second active position, the shoulder structure 110 is engaged with the second end of the sealing sleeve 310. The end of the pull rod 320 away from the sealing sleeve 310 continues moving towards the outside of the internal cavity of the oil cup 100. The pull rod 320 disconnects from the second end of the sealing sleeve 310. It should be noted that the shoulder structure 110 is positioned at the interface between the end of the second open end of the oil cup 100 and the sealing connection segment 120.

[0048] During use, by pulling the pull rod 320 away from the oil cup 100, the sealing sleeve 310 is driven to move towards the second open end of the oil cup 100 until the position where the sealing sleeve 310 and the pull rod 320 are connected engages with the shoulder structure 110, and the user will feel resistance when pulling the pull rod 320. At this time, if the user continues to pull the pull rod 320 in the direction away from the oil cup 100, the shoulder structure 110 grips the sealing sleeve 310, causing the pull rod 320 to break away from the sealing sleeve 310, thereby completing the movement of the oil core separation section 300.

[0049] In some embodiments, the material of the sealing sleeve 310 can be selected as a flexible non-metallic material, such as rubber or other applicable materials that those skilled in the art may recognize, and a detailed listing is not provided here.

[0050] Furthermore, a detailed introduction to the structure of the sealing sleeve 310 is provided. The sealing sleeve 310 includes a first sealing sub-sleeve 311 and a second sealing sub-sleeve 312.

[0051] A first end of the first sealing sub-sleeve 311 is coaxially and movably connected to the second end of the atomization core section 200, and the first end of the first sealing sub-sleeve 311 is fitted over the second end of the atomization core section 200.

[0052] A first end of the second sealing sub-sleeve 312 is abutted against the second end of the first sealing sub-sleeve 311. The second end of the second sealing sub-sleeve 312 is coaxially and movably connected to the second open end of the oil cup 100, and the second end of the second sealing sub-sleeve 312 is connected to the end of the pull rod 320 that is close to the sealing sleeve 310.

[0053] It should be noted that the axial diameter of the first sealing sub-sleeve 311 needs to be greater than the axial diameter of the second sealing sub-sleeve 312.

[0054] In some embodiments, at least one sealing ring 313 is provided on the second sealing sub-sleeve 312, which helps ensure the sealing connection between the second sealing sub-sleeve 312 and the sealing connection segment 120 extending into the internal cavity of the oil cup 100, thereby ensuring the sealing of the internal cavity of the oil cup.

[0055] In some embodiments, the second sealing sub-sleeve 312 is tightly fitted with the sealing connection segment 120 extending into the internal cavity of the oil cup 100, aiding in sealing the internal cavity of the oil cup.

[0056] In one embodiment of the present application, the atomization core section 200 includes a bracket 210, an atomization core assembly 220, and oil-absorbent cotton 230. The bracket 210 is mounted on the first open end of the oil cup 100. The atomization core assembly 220 is mounted on the bracket 210. The oil-absorbent cotton 230 is housed within the atomization core assembly 220.

[0057] It should be noted that the position of the oil inlet 240 on the atomization core assembly 220 is not specifically limited here, as long as it can satisfy that the movement of the first end of the oil core separation section 300 can achieve coverage over or exposure of the oil inlet 240 of the atomization core section 200. Accordingly, the structure of the first end of the oil core separation section 300 can be adaptively adjusted based on the position of the oil inlet 240 on the atomization core assembly 220.

[0058] The present application further provides an electronic atomizing equipment, including: any of the atomization devices as described above and an electronic device configured to power the atomization device. The specific structure of the atomization device refers to the embodiments described above and will not be elaborated here.

[0059] The technical features of the aforementioned embodiments can be combined in any manner. To keep the description concise, not every possible combination of the technical features in the above embodiments has been detailed. However, as long as these combinations of technical features do not present any contradictions, they should be considered within the scope of this description.

[0060] The above embodiments express several possible implementations of the present application. The descriptions are specific and detailed; however, this should not be understood as limiting the scope of the present application. It should be noted that those skilled in the art may make various modifications and improvements without departing from the concept of the present application, and these are all within the scope of protection of this application. Therefore, the scope of protection of the present application shall be defined by the appended claims.
