[0028] The specific structure of the atomization device will be mainly described below.

[0029] Referring to Figs. 1 to 4 In the embodiments of the present application, the atomization device is used to combine with the power supply device into an atomization equipment, and the atomization device comprises:

[0030] A main shell 1, an oil injection cavity 11 and an oil storage cavity 12 are formed in the main shell 1, and a movable channel 13 is formed on the main shell 1, two ends of the movable channel 13 are respectively communicated with the outside of the atomization equipment and the oil injection cavity 12, an oil injection hole 121 is arranged on the cavity wall of the oil injection cavity 12, and the atomization substrate in the oil injection cavity 12 enters the oil storage cavity through the oil injection hole 121;

[0031] A sealing member 2 is movably arranged in the movable channel 13, the sealing member 2 comprises a connecting section 21 and a plugging section 22 connected with each other, at least part of the connecting section 21 is located in the movable channel 13, and the plugging section 22 is located in the oil injection cavity 12 and is used to plug or open the oil injection hole 121;

[0032] The sealing member 2 has a plugging position and an oil injection position, in the plugging position, the plugging section 22 abuts against the hole wall of the oil injection hole 121 to plug the oil injection hole 121, and in the oil injection position, the plugging section 22 has an oil passing gap with the oil injection hole 121;

[0033] The atomization device further comprises a limiting assembly 4 connected with the connecting section 21, which can keep the sealing piece 2 in the oil blocking position or the oil injection position.

[0034] Specifically, in the embodiments of the present application, the limiting assembly 4 and the connecting section 21 of the sealing piece 2 can be connected in many ways, such as screw connection, clamping, bonding or welding, etc. The size of the sealing section 22 of the sealing piece 2 matches the size of the oil injection hole 121, so that when the sealing piece 2 moves to the oil blocking position, the sealing section 22 can completely block the oil injection hole 121.

[0035] When using the atomization device, when the user needs to supplement the atomization substrate in the oil injection cavity 11, the sealing piece 2 can be operated to the oil injection position, and after the sealing piece 2 reaches the oil injection position, the limiting assembly 4 can keep the sealing piece 2 in the oil injection position; when the user does not need to supplement the atomization substrate in the oil injection cavity 11, the sealing piece 2 can be operated to the oil blocking position, and after the sealing piece 2 reaches the oil blocking position, the limiting assembly 4 can keep the sealing piece 2 in the oil blocking position. In this way, whether the user needs to inject oil or block oil, the user only needs to release the hand after operating the sealing piece 2 to move to the oil injection position or the oil blocking position, and after the user releases the control of the sealing piece 2, the sealing piece 2 will be kept in the oil injection position or the oil blocking position by the limiting assembly 4, without the user continuously exerting force to keep the sealing piece in the oil injection position or the oil blocking position.

[0036] For the specific setting of the limiting assembly 4, in some embodiments, the limiting assembly 4 can include a guide column 41, a guide cylinder 42 and an elastic piece 3, the guide column 41 is fixedly connected with the end of the connecting section 21 away from the blocking section 22, the guide cylinder 42 is fixedly arranged on the outer housing 1, the guide column 41 is provided with a guide protrusion 411 on the peripheral surface, the guide cylinder 42 is provided with a guide groove 421 on the inner peripheral surface, the guide protrusion 411 and the guide groove 421 are connected in sliding fit, and at least part of the elastic piece 3 is arranged in the movable channel 13, one end of the elastic piece 3 is connected with the sealing piece 2, and the elastic piece 3 is used to provide the sealing piece 2 with a force in the direction that can drive the blocking section 22 to move towards the movable channel 13.

[0037] Specifically, the elastic piece 3 can be a spring or other element capable of providing elastic force. It is worth mentioning that at least part of the elastic piece 3 is arranged in the movable channel 13, and its specific position can be sleeved on the outer periphery of the blocking section 22 or the connecting section 21, and can be arranged in compression or in tension, which is not strictly limited here, as long as the elastic piece 3 can be used to provide the sealing piece 2 with a force in the direction that can drive the blocking section 22 to move towards the movable channel 13.

[0038] The technical scheme of the present application sets the guide column 41, the guide cylinder 42 and the elastic member 3, so that the movement of the sealing member 2 connected with the limiting assembly 4 is limited by the sliding cooperation of the guide protrusion 411 and the guide groove 421, thereby limiting the sealing member 2, and further, the elastic member 3 provides the sealing member 2 with a force in a direction capable of driving the blocking section 22 to move towards the movable channel 13, so that the atomization device can continuously provide sufficient force to maintain the oil injection position when the sealing member 2 is located at the oil injection position.

[0039] In some embodiments, the guide groove 421 can include a first retaining section 4211 and a movable section 4212, the first retaining section 4211 is a groove extending along the circumference of the guide cylinder 42, and the movable section 4212 is a groove extending along the axis of the guide cylinder 42, and the first retaining section 4211 communicates with the movable section 4212 at one end close to the blocking section 22.

[0040] As can be easily understood, when the guide protrusion 411 is located in the first retaining section 4211, the sealing member 2 is located at the oil blocking position, at this time, since the first retaining section 4211 is a groove extending along the circumference of the guide cylinder 42, the guide protrusion 411 cannot move along the axis of the guide cylinder 42, that is, the sealing member 2 is kept in the oil blocking position by the limiting assembly 4; when the user needs to inject oil, the user only needs to rotate the guide protrusion 411 to the intersection of the first retaining section 4211 and the movable section 4212, since the movable section 4212 is set as a groove extending along the axis of the guide cylinder 42, at this time, the guide protrusion 411 can move along the axis of the guide cylinder 42, and further, since the elastic member 3 provides the sealing member 2 with a force in a direction capable of driving the blocking section 22 to move towards the movable channel 13, the user does not need to manually drive the guide protrusion 411 to move along the axis of the guide cylinder 42, and the guide protrusion 411 will automatically move to the oil injection position under the action of the elastic member 3.

[0041] In some embodiments, in order to make the relative movement between the guide column 41 and the guide cylinder 42 more stable, the guide protrusion 411 can be provided as two, the two guide protrusions 411 are respectively arranged on opposite sides of the guide column 41, and the guide groove 421 has two, the guide groove 421 is arranged one by one with the guide protrusion 411.

[0042] In some embodiments, in order to facilitate the installation of the elastic member 3 and make it provide the required elastic force, the elastic member 3 is compressed and arranged in the movable channel 13, one end of the elastic member 3 abuts against one end of the guide column 41 close to the connecting section 11, and the other end of the elastic member 3 abuts against the annular boss 131 arranged in the movable channel 13. Specifically, the annular boss 131 is a circular annular boss with a central hole, the annular boss 131 is fixed on the inner wall of the movable channel 13, and the annular boss 131 can be arranged as a circular annular step in which the inner wall of the movable channel 13 protrudes radially towards the center of the channel.

[0043] In some embodiments, the first retaining section 4211 is provided with a first notch 4213 extending in the axial direction of the guide cylinder 42 and towards the direction away from the plugging section 12. It is easy to understand that when the guide protrusion 411 is located in the first retaining section 4211, the guide column 41 can be rotated to drive the guide protrusion 411 to move along the first retaining section 4211. However, the user may, due to friction or other accidental situations, cause the guide column 41 to rotate undesirably during the use of the atomization device, which may further cause the guide protrusion 411 to rotate to the intersection of the first retaining section 4211 and the movable section 4212 and accidentally leave the oil plugging position; and the arrangement of the first notch 4213 enables the guide protrusion 411 to be clamped into the first notch 4213 when it is located in the first retaining section 4211. In this way, the guide protrusion 411 cannot easily leave the oil plugging position due to the undesired rotation of the guide column 41 when it is located in the first retaining section 4211. Only when the user needs the guide protrusion 411 to leave the first retaining section, the user first presses the guide column 41 slightly to make the guide protrusion 411 exit the first notch 4213, and then rotates the guide column 41 to make it leave the first retaining section 4211. It is worth mentioning that in the atomization device of the present application, the sealing member 2 can still maintain good sealing effect on the oil injection hole 121 when the guide protrusion 411 is clamped into the first notch 4213. On the one hand, the notch depth of the first notch 4213 is limited, and on the other hand, the cooperation between the plugging section 22 and the oil injection hole 121 can be arranged as an interference fit when the oil is plugged, and the interference fit is still maintained when the guide protrusion 411 is clamped into the first notch 4213, or the plugging section 22 can be arranged as a slightly longer cylinder, and the plugging section 22 is still inserted into the oil injection hole 121 to achieve plugging when the guide protrusion 411 is clamped into the first notch 4213. The technical solution of the present application enables the sealing member 2 to be more stably and reliably maintained in the oil plugging position, thereby improving the reliability of the atomization device.

[0044] In order to enable the sealing member 2 to be more stably and reliably kept in the oil injection position, the guide groove 421 can further comprise a second retaining section (not shown), which is a groove extending along the circumference of the guide cylinder, and which is in communication with one end of the movable section away from the blocking section. Similar to the first retaining section 4211, since the second retaining section is a groove extending along the circumference of the guide cylinder 42, the guide protrusion 411 cannot move in the axial direction of the guide cylinder 42 when it is located in the second retaining section. In this way, the sealing member 2 is kept in the oil injection position by the limiting assembly 4; or, by cooperating with the elastic member 3 through certain limiting structures, the sealing member 2 is kept in the oil injection position. In some embodiments, the cross-sectional area of the end of the blocking section 22 close to the movable passage can be set to be larger than the cross-sectional area of the end of the movable passage close to the blocking section. In some embodiments, the connecting section 21 can be provided with a small-diameter section and a large-diameter section, the small-diameter section is inserted into the central hole of the annular boss 131, the small-diameter section, the large-diameter section and the blocking section 22 are sequentially connected, and the cross-sectional area of the large-diameter section is larger than the cross-sectional area of the central hole of the annular boss. In this way, the elastic member 3 can push the sealing member 2 to the limiting structure, thereby keeping the sealing member 2 in the oil injection position.

[0045] Similar to the first gap 4213, in the technical solution of the present application, the second retaining section can also be provided with a second gap (not shown) extending in the axial direction of the guide cylinder 42 and away from the blocking section 22. In this way, the sealing member 2 can be more stably and reliably kept in the oil injection position, and the reliability of the atomization device is improved.

[0046] In some embodiments, in order to facilitate user operation, the limiting assembly 4 can further comprise a knob cover 43, which is fixedly connected to one end of the guide column 41 away from the connecting section 21, and the knob cover 43 is provided with an anti-slip structure.

[0047] The above description is only the preferred embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made by using the contents of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
