[0022] In this embodiment,

[0023] like Figures 1 to 5 As shown, the utility model provides a button unlocking structure of a sealing device, including a sealing device body 1, wherein the sealing device body 1 includes a sealing cover body 2 and a sealing base body 3 axially connected to the sealing cover body 2, and a single-button unlocking unit 4 is provided on the sealing cover body 2, and the single-button unlocking unit 4 includes an unlocking component 5 arranged in the sealing cover body 2 and an unlocking button 14 arranged at the front end or rear end of the sealing cover body 2; the sealing cover body 2 and the sealing base body 3 are unlocked by the unlocking button 14 cooperating with the unlocking component 5 switch.

[0024] The design of the single-button unlocking unit 4 greatly simplifies the unlocking operation of the sealer, and the user can complete the unlocking with one hand, which improves the user's convenience. Secondly, the structural design of the unlocking component 5 ensures the reliability and stability of the unlocking, and reduces the possibility of failure.

[0025] The unlocking assembly 5 includes an exhaust assembly 6 and connecting rods 7 respectively arranged on the left and right sides of the sealing cover body 2, a rotating column 8 is arranged in the sealing cover body 2, and the connecting rod 7 is passed through the rotating column 8; the connecting rod 7 includes a pressing end 9 and a hook end 10; a fixing plate 26 for fixing the connecting rod is arranged above the hook end; a first elastic member 11 is arranged on the hook end 10; a latch tooth 12 is arranged on the sealing seat body 3; a side hole 13 is arranged on the sealing cover body 2 corresponding to the latch tooth 12, and the hook end 10 is passed through the side hole 13 and connected with the latch tooth 12 by a buckle 15.

[0026] The hook end 10 of the connecting rod 7 is connected with the buckle 15 of the latch tooth 12 to ensure that the sealing cover body 2 and the sealing base body 3 are firmly connected when closed. At the same time, the first elastic member 11 provides appropriate elastic recovery to ensure that the unlocking and locking processes are smooth and reliable.

[0027] The unlocking button 14 is provided with a buckle 15, a pressing column 16 and a second elastic member 17 arranged between the sealing cover body 2 and the unlocking button 14; the unlocking button 14 is arranged on the sealing cover body 2 through the buckle 15; the pressing column 16 passes through the sealing cover body 2 and is in contact with the pressing end 9; the sealing cover body 2 drives the hook end 10 to disengage from the locking tooth 12 and unlock and unfold through the unlocking button 14 and the pressing column 16 in cooperation with the connecting rod 7.

[0028] The unlocking operation can be achieved with a single button, which is convenient and quick, improving the user experience.

[0029] The exhaust assembly 6 comprises:

[0030] A through hole column 18, wherein the through hole column 18 is arranged in the sealing cover body 2;

[0031] A connecting hole column 19, wherein the connecting hole column 19 is arranged on the connecting rod 7;

[0032] A sealing hole column 20, wherein the sealing hole column 20 and the connecting hole column 19 are arranged on the connecting rod 7 adjacently, and the connecting hole column 19 is connected to the sealing hole column 20;

[0033] An exhaust pipe 21, the exhaust pipe 21 is used to connect the exhaust hole column and the connecting rod 7 hole column;

[0034] The sealing member 22 is disposed in the sealing cover 2 and is in contact with the sealing hole column 20 .

[0035] When the sealer body 1 is in use, due to vacuum sealing, the air pressure inside the sealer body 1 is unbalanced with the external air pressure. By setting the exhaust component 6 to exhaust and release pressure, the air pressure inside the sealer body 1 can be effectively balanced with the external air pressure, thereby ensuring that the unlocking and locking process is smooth and reliable, thereby improving the sealing effect and safety of use.

[0036] An electric control unit 23 is also provided in the sealing cover 2; a power-off contact 24 for controlling the electric control unit 23 is provided on the sealing cover 2, and a power-off protrusion 25 is provided on the sealing seat 3; when the sealing cover 2 and the sealing seat 3 are opened, the power-off contact 24 and the power-off protrusion 25 are separated and the electric control unit 23 is closed; when the sealing cover 2 and the sealing seat 3 are closed, the power-off contact 24 and the power-off protrusion 25 are closed and the electric control unit 23 is opened.

[0037] The opening and closing of the electric control unit 23 is achieved by the cooperation of the power-off contact 24 and the power-off protrusion 25, so that when the user flips the sealer to open, it is in a separated power-off state, and when the user flips the sealer to close, it is in a closed power-on state, thereby improving safety and energy saving.

[0038] like Figures 1 to 5 As shown, when the user uses it, by pressing the unlock button 14, the pressing column 16 and the pressing end 9 of the connecting rod 7 are driven to move. The connecting rod 7 moves toward the connecting rod 7 through the pressing column 16 to cooperate with the rotating column 8 to rotate, and the sealing hole column 20 on the connecting rod 7 is separated from the sealing member 22 as the connecting rod 7 moves, and the through-hole column 18 is connected with the connecting hole column 19 through the exhaust pipe 21, so as to ensure that the air pressure between the sealing cover body 2 and the sealing cover body 2 is balanced with the air pressure of the outside. At the same time, as the connecting rod 7 rotates, the buckle 15 end of the connecting rod 7 is disengaged from the latch tooth 12 in the side hole 13, and the sealing cover body 2 can be flipped open, and the power-off contact 24 provided on the sealing cover body 2 and the power-off protrusion 25 provided on the sealing seat body 3 are separated as the sealing cover body 2 is flipped open, so that the electric control unit 23 in the sealing cover body 2 is turned off and powered off through the separation of the power-off contact 24 and the power-off protrusion 25, which improves safety and energy saving.
