Refer to FIG. 1 to FIG. 7, the present disclosure discloses an atomization assembly of aerosol generating device. The atomization assembly 100 of aerosol generating device comprises a shell 110, a sealing seat 120, an atomization core 130, and seal 140. The atomization core 130 are provided with two opposite ends. One end of the atomization core 130 is connected to the shell 110, and the other end of the atomization core 130 is mounted on the sealing seat 120. The shell 110, the sealing seat 120, and the atomization core 130 are enclosed to form a juice storage cavity 150. The atomization core 130 is provided with a passing juice orifice 131, wherein the seal 140 comprise a sealing part 141 in the juice storage cavity 150 and a push rod 142 connected to the sealing part 141. The sealing part 141 is arranged surround peripheral surface of the atomization core 130 for covering the passing juice orifice 131, and free end of the push rod 142 is slidably arranged through the sealing seat 120 and exposed outside the sealing seat 120.

Specifically, the shell 110 has an end with opening. The sealing seat 120 is mounted at the open end of the shell 110, and the sealing seat 120 seals the open end of the shell 110. The atomization core 130 is located between the shell 110 and the sealing seat 120. The atomization core 130 is hollow to form an air flow channel. The shell 110 is provided with a suction port which communicates with the air flow channel, and the sealing seat 120 is provided with an air hole which communicates with the air flow channel. The atomization core 130, the sealing seat 120, and the shell 110 are enclosed to form a juice storage cavity 150. The juice storage cavity 150 is used to store the atomization base material. The atomization matrix can be tobacco juice, and the atomization core 130 heats the atomization base material to generate aerosol for users to smoke. In this technical scheme, the atomization base material is tobacco juice, which is used as an example. The passing juice orifice 131 is arranged on the side wall of the atomization core 130, and the passing juice orifice 131 is arranged along the radial direction of the atomization core 130. Without consideration of the action of the seal 140, the passing juice orifice 131 will communicate with the juice storage cavity 150.

In some embodiments, the sealing part 141 of said seal 140 is arranged inside the juice storage cavity 150. The sealing part 141 is abutted against the atomization core 130, and the sealing part 141 closes the passing juice orifice 131 to avoid juice leaking through the passing juice orifice 131 to the outside of the atomization assembly 100 when the atomization assembly 100 is standing or long-distance transportation. The leakage may cause the waste of tobacco juice and tobacco juice leakage on the bottom of atomization assembly 100.

It is worth to clarify that one end of the push rod 142 connects with the sealing part 141, and the free end of the push rod 142 exposes outside the sealing seat 120. The push rod 142 can be arranged in a long strip shape, so that the push rod 142 can be slidably connected with the sealing seat 120 and moved along the axial direction of the atomization core 130. The push rod 142 is integrally formed with the sealing part 141, which increases the connection strength between the push rod 142 and the sealing part 141, facilitating the structural molding of the seal 140, as well as the push rod 142's driven of said sealing part 141 to move.

By adopting above technical scheme, the passing juice orifice 131 is closed inside the juice storage cavity 150 by the sealing part 141, which facilitates long-term storage of the atomization assembly 100 and long-distance transportation of the atomization assembly 100. When the atomization assembly 100 is required, the push rod 142 pushes the sealing part 141 towards the axial direction of the atomization core 130, so that the sealing part 141 is arranged to expose the passing juice orifice 131, thus facilitating the tobacco juice to contact with the heat release element of the atomization core 130 through the passing juice orifice 131 to generate aerosol for users to smoke. The passing juice orifice 131 is stagger-arranged with the push rod 142, that is, the push rod 142 will not cover the passing juice orifice 131 when the push rod 142 pushes the sealing part 141. Under the action of the sealing part 141 and the push rod 142, the waste of tobacco juice is avoided and the clean appearance of the atomization assembly 100 is guaranteed. The push rod 142 outside the atomization assembly 100 is pushed by user and moves towards the atomization core 130, so that the seal 140 moves upward and makes the passing juice orifice 131 communicate with the juice storage cavity 150.

In case the atomization assembly 100 needs to be standing for a period of time and avoid leakage of tobacco juice at the passing juice orifice 131, the push rod 142 can be pulled to move outward, that is, the push rod 142 drives the sealing part 141 to move downward, so that the passing juice orifice 131 can be closed again by the sealing part 141 to avoid leakage of tobacco juice at the passing juice orifice 131 again, which improves the user's experience of atomization assembly 100.

Since the sealing part 141 is always accommodated in the juice storage cavity 150, when the push rod 142 pushes the sealing part 141 to move upward, the sealing part 141 will not lead to the increase of pressure in the juice storage cavity 150, which will lead to leakage of tobacco juice at the passing juice orifice 131.

In an optional embodiment, the sealing part 141 is sleeved on outer peripheral surface of the atomization core 130. The sealing part 141 is arranged in a sleeve shape, that is, the sealing part 141 is hollow, and the side wall of the atomization core 130 is abutted against the inner wall of the sealing part 141 to achieve the effect of closing the passing juice orifice 131. In this embodiment, the sealing part 141 is arranged in a round platform tubular shape. The sealing part 141 is arranged in hollow along the axis direction. The sealing part 141 is a plastic part. The small diameter end of the sealing part 141 is mounted on the top of the atomization core 130, and the large diameter end of the sealing part 141 is mounted on the bottom of the atomization core 130, which facilitates the push rod 142 to push the sealing part 141 to move upward from the bottom of the sealing part 141. The sealing part 141 is arranged in a round table shape, which facilitates tight sealing of the passing juice orifice 131.

In an optional embodiment, the seal 140 comprises two push rods 142. The two push rods 142 are symmetrically arranged with each other, and the push rod 142 and the passing juice orifice 131 are stagger arranged with each other. During the push rod 142 is pushed upward, the push rod 142 is prevented from closing the passing juice orifice 131. The two push rods 142 are arranged, so that the push rod 142 can smoothly drive the sealing part 141 to move in the juice storage cavity 150.

In an optional embodiment, the sealing seat 120 comprises a silicone pad 121, which is airtight connected to the shell 110, the silicone pad 121 is provided with a mounting hole (not shown in the figure) for the push rod 142 to pass through, and the push rod 142 is interference fit with the mounting hole (not shown in the figure). In this embodiment, the side wall of silicone pad 121 is provided with a plurality of circular convex platforms, and the circular convex platforms are connected with the side wall at the bottom end of the shell 110 to close the bottom end of the sealing seat 120. Mounting holes are arranged at the bottom of the silicone pad 121, and the push rod 142 is interference fitted with the mounting hole (not shown in the figure). During the push rod 142 pushes the sealing part 141 along the mounting hole (not shown in the figure), leakage of tobacco juice from the mounting holes (not shown in the figure) can be avoided.

It should be understood that the cross-section of the push rod 142 can be a variety of shapes. For example, the cross-section of the push rod 142 can be square or circular. Meanwhile, area of the cross-section of the push rod 142 is increased along the direction away from the sealing part 141. During the push rod 142 is pushed, the push rod 142 still tightly fits with the mounting hole to avoid leakage of tobacco juice.

In an optional embodiment, the shell 110 comprises a shell body 111, a juice sealing plug 113, and an outer cover 112. A juice injection hole 114 is provided on the top of the shell body 111. After tobacco juice is added into the juice storage cavity 150, the juice sealing plug 113 is mounted at the juice injection hole 114. The juice sealing plug 113 is made of silica gel material. The juice injection hole 114 is closed by the juice sealing plug 113. The outer cover 112 is connected to the shell body 111 in buckle connection and covers the juice sealing plug 113. The outer cover 112 is arranged in an arc shape, and a concave hole is provided concavely on the shell body 111.
