[0031] See also Figure 1 and Figure 5The embodiment of the utility model provides a sealing machine, including a sealing machine housing 1, a base 12 and a pressing assembly 2 are arranged on the sealing machine housing 1, a pressing sheet 21 is arranged on the pressing assembly 2, an opening 11 for placing the sealed object is arranged on the sealing machine housing 1, and the pressing assembly 2 is pressed to move the pressing sheet 21 toward the base 12 for sealing. A convex block 22 is arranged on the pressing assembly 2, a switch assembly 3 is arranged on the sealing machine housing 1, and a baffle 31 is arranged on the switch assembly 3. When the baffle 31 abuts against the convex block 22, the pressing assembly 2 cannot be pressed, and when the baffle 31 abuts against the convex block 22, the pressing assembly 2 can be pressed freely.

[0032] Specifically, during use, when the switch assembly 3 moves to the left, the blocking piece 31 just contacts the protrusion 22 of the pressing assembly 2, the pressing assembly cannot be pressed, and the pressing piece 21 cannot move downward to contact the base 12. When the switch assembly 3 moves to the right, the blocking piece 31 separates from the protrusion 22, and when the pressing assembly 2 is pressed, the pressing piece 21 can move downward. When sealing a plastic bag, it is only necessary to put the bag mouth of the plastic bag into the base 12 of the opening 11, and the pressing piece 21 moves downward, and the pressing piece 21 and the base 12 press the plastic bag tightly to perform heat sealing. The heat sealing principle of the pressing piece 21 and the base 12 is the same as the heat sealing principle of the existing sealing machine. This principle is a prior art and will not be repeated here.

[0033] See also Figure 1 In an optional embodiment, the opening 11 is U-shaped. The pressing sheet 21 and the base 12 are respectively located on both sides of the opening 11, i.e., the upper and lower sides. When the pressing sheet 21 moves downward, heat sealing is performed, and when it moves upward, heat sealing is stopped. A simple pressing component 2 is used to control whether to heat seal. Compared with the existing sealing machine that heat seals in two parts hingedly, the structure is simpler and the operation is more convenient.

[0034] See also Figure 1 and Figure 4 In an optional embodiment, the pressing assembly 2 includes a button 23 extending out of the sealing machine housing 1, and the button 23 is rotatably arranged on the sealing machine housing 1. The switch assembly 3 includes a transverse shift switch 32, a transverse shift rod 33 controlled to move by the transverse shift switch 32, and a blocking piece 31 is arranged on a side of the transverse shift rod 33 close to the opening 11. A track piece 14 is arranged in the sealing machine housing 1 to support the movement of the transverse shift rod 33. A convex strip 321 is arranged on the transverse shift switch 32.

[0035] Specifically, when the finger pushes the convex strip 321 to the right, the lateral switch 32 drives the lateral rod 33 to move to the left along the track sheet 14, and the blocking sheet 31 abuts against the convex strip 22 of the button 23 to prevent the button 23 from rotating due to accidental touch, and heat sealing is performed without knowing it, which may cause danger. When the finger pushes the convex strip 321 to the left, the button 23 can rotate freely and can be sealed at any time.

[0036] In an optional embodiment, the button 23 may also be movable up and down, and the principle of the switch assembly 3 controlling whether the button 23 is active is the same as the principle of the button 23 rotating as described above.

[0037] See also Figure 4 and Figure 5 In an optional embodiment, the button 23 is at least partially configured to be arc-shaped, and an arc-shaped limiting piece 13 for limiting the button 23 is provided on the sealing machine housing 1. Preferably, the button 23 is cylindrical, and there are two arc-shaped limiting pieces 13, which are symmetrically arranged on both sides of the button 23, so that the button 23 moves along the track, thereby extending the service life of the button. Figure 4 A schematic diagram of the structure when the button 23 is at the highest position. Figure 5 It is a schematic diagram of the structure when the button 23 is pressed to the lowest position.

[0038] See also Figure 6 In an optional embodiment, in order for the button to rebound automatically, a spring column 15 is provided between the sealing machine housing 1 and the button 23, and a spring is provided in the spring column 15. Each time the button 23 is pressed, the button 23 is released, and the spring rebounds the button 23 to the highest point.

[0039] See also Figure 2 In an optional embodiment, a battery installation slot 16 is provided in the sealing machine housing 1 , and a removable outer cover 17 is provided outside the battery installation slot 16 . Embodiment 2
