[0006] The sealing device provided by the application comprises a first body, a second body, a seat body and a sealing component. The second body has a closed state and an open state relative to the first body. The seat body is arranged on the second body and is provided with a vacuum cavity and a first liquid outlet. The first liquid outlet is in communication with the vacuum cavity. The sealing component is arranged on the second body. When a user performs vacuum sealing on a preservation bag by using the sealing device, the vacuum cavity can be used to perform vacuum treatment on the sealed bag, thereby realizing vacuum sealing of the sealed bag. The sealing device can discharge the gas in the sealed bag. When the sealed bag contains liquid, the liquid can be drawn into the vacuum cavity. Since the first liquid outlet is in communication with the vacuum cavity, the first liquid outlet can discharge the liquid in the vacuum cavity, thereby realizing external discharge of the liquid in the sealing device and facilitating user operation. When the second body is in the closed state relative to the first body, the sealing device is in a vacuum sealing state, and the sealing component blocks the first liquid outlet, thereby preventing air leakage when the sealed bag is in a vacuum state, improving the airtightness of the vacuum cavity and improving the sealing effect. When the second body is in the open state relative to the first body, the sealing device ends the sealing work on the sealed bag, the sealing component is separated from the first liquid outlet, and the accumulated liquid in the vacuum cavity can be discharged, thereby realizing automatic discharge of the liquid drawn from the sealed bag by separating the first body and the second body after the sealing work of the sealing device is completed. The user does not need to manually pour out the accumulated liquid in the sealing device, the operation difficulty is reduced, the operation steps are simplified, and the user experience is improved.

[0007] By opening and closing the first body, the first body and the second body are mutually closed or mutually opened, thereby controlling the opening or blocking of the first liquid outlet by the sealing component. While ensuring the sealing of the vacuum cavity, the liquid drawn from the sealed bag can be automatically discharged after the first body and the second body are separated, without the need for the user to manually pour out the accumulated liquid in the sealing device, thereby simplifying the operation steps.

[0008] Meanwhile, since the sealing component can automatically control the opening and closing of the first liquid outlet according to the working condition of the sealing device, the automatic drainage function of the sealing device can be realized, the accumulation of liquid in the sealing device is avoided, and the user is prevented from forgetting to clean the accumulated liquid in the sealing device after sealing food materials by using the sealing device.

[0071] ​The sealing device 100 provided by the application comprises a first body 110, a second body 120, a seat body 130 and a sealing component 140. The second body 120 has a closed state and an open state relative to the first body 110. The seat body 130 is arranged on the second body 120. The seat body 130 is provided with a vacuum cavity 132 and a first liquid outlet 134. The first liquid outlet 134 is in communication with the vacuum cavity 132. The sealing component 140 is arranged on the second body 120. When a user performs vacuum sealing on a fresh-keeping bag by using the sealing device 100, the sealed bag can be subjected to vacuum treatment through the vacuum cavity 132, so as to realize vacuum sealing of the sealed bag. The sealing device 100 can discharge the gas in the sealed bag. When the sealed bag contains liquid, the liquid can be sucked into the vacuum cavity 132. Since the first liquid outlet 134 is in communication with the vacuum cavity 132, the first liquid outlet 134 can discharge the liquid in the vacuum cavity 132, so as to realize external discharge of the liquid in the sealing device 100 and facilitate user operation. When the second body 120 is in the closed state relative to the first body 110, the sealing device 100 is in a vacuum sealing state. The sealing component 140 seals the first liquid outlet 134, so as to avoid gas leakage when the sealed bag is subjected to vacuum, improve the airtightness of the vacuum cavity 132 and improve the sealing effect. When the second body 120 is in the open state relative to the first body 110, the sealing device 100 ends the sealing work on the sealed bag. The sealing component 140 is separated from the first liquid outlet 134, so as to discharge the liquid accumulated in the vacuum cavity 132. Thus, after the sealing work of the sealing device 100 is ended, the liquid sucked from the sealed bag can be automatically discharged, and the user no longer needs to manually pour the liquid accumulated in the sealing device 100, so as to reduce the operation difficulty, simplify the operation steps and improve the user experience.

[0072] Meanwhile, since the sealing component 140 can automatically control the opening and closing of the first liquid outlet 134 according to the working condition of the sealing device 100, the automatic drainage function of the sealing device 100 can be realized, the liquid in the sealing device 100 can be prevented from accumulating and the user can be prevented from forgetting to clean the accumulated liquid after the food material is sealed by using the sealing device 100. In this way, the operation convenience is provided, the cleaning efficiency of the sealing device 100 is improved, the probability of breeding bacteria by the accumulated liquid is reduced and the user is facilitated to use.

[0073] Specifically, when the second body 120 is in the closed state relative to the first body 110, the sealing component 140 can effectively seal the first liquid outlet 134, so as to ensure that the liquid or gas in the vacuum cavity 132 will not leak, improve the sealing property of the sealed bag and help to maintain the quality of the food material in the package and prolong the shelf life.

[0074] Further, when the user uses the sealing device 100, the user places the preservation bag or the sealed bag in the vacuum cavity 132, and then buckles the first body 110 and the second body 120, at this time, the second body 120 is in the closed state relative to the first body 110, at this time, the first liquid outlet 134 is blocked by the blocking component 140, thereby sealing the vacuum cavity 132, at this time, the first body 110 and the second body 120 complete the closing action, and the sealing device 100 can perform the vacuumizing work on the sealed bag or the preservation bag, during the process, the liquid in the sealed bag or the preservation bag is extracted and flows into the vacuum cavity 132, and then gathers at the bottom of the vacuum cavity 132 along the inner wall of the vacuum cavity 132, when the sealing device 100 completes the work, the user can open the first body 110 and the second body 120, so that the second body 120 is in the open state relative to the first body 110, the first body 110 is displaced away from the second body 120, the first body 110 no longer presses the first end of the blocking component 140, thereby no longer triggering the blocking component 140, the blocking component 140 resets, and is away from the first liquid outlet 134, the first liquid outlet 134 is opened, the liquid accumulated in the vacuum cavity 132 can be guided, and the internal liquid is naturally discharged to the outside of the sealing device 100, thereby realizing the self-draining function of the sealing device 100.
