[0032] Reference Figures 1 to 5 An embodiment of the present invention provides a vacuum sealer, which includes a base 100 , a flip cover 200 and a connecting rod assembly 300 .

[0033] The base 100 is provided with a vacuum chamber 110, the top of the vacuum chamber 110 has an opening 111, the flip cover 200 is rotatably connected to the base 100, the base 100 is provided with a connecting rod assembly 300, the flip cover 200 is provided with a locking block 210, and the connecting rod assembly 300 is provided with an abutment block 332, wherein the connecting rod assembly 300 is used to drive the abutment block 332 to move to abut against the locking block 210, so that the flip cover 200 that is flipped to close the opening 111 is connected and locked with the base 100.

[0034] It is understandable that the connecting rod assembly 300 can also drive the abutting block 332 to move to release the abutment with the locking block 210 , so that the flip cover 200 can rotate relative to the base 100 .

[0035] The connecting rod assembly 300 drives the abutment block 332 to move to abut against the locking block 210, so that the flip cover 200 that is flipped over to close the opening 111 is connected and locked with the base 100. Through the above structure, the connection and locking of the flip cover 200 and the base 100 can be achieved without the participation of the electromagnetic block assembly. The cost of purchasing the connecting rod assembly 300 is lower than that of the electromagnetic block assembly. Therefore, the production cost of the vacuum sealer can be reduced.

[0036] In some embodiments, the base 100 is provided with the locking block 210 , and the flip cover 200 is provided with the connecting rod assembly 300 .

[0037] The connecting rod assembly 300 includes an input rod 310 , a transmission rod 320 , and an abutment rod 330 .

[0038] Reference Figure 3The input rod 310 is rotatably connected to the base 100, and a first connecting block 311 is provided on the outer side of the input rod 310. The transmission rod 320 is rotatably connected to the base 100, and a second connecting block 321 and a third connecting block 322 are provided on the outer side of the transmission rod 320. The second connecting block 321 and the first connecting block 311 are rotatably connected. The abutment rod 330 is rotatably connected to the base 100, and a fourth connecting block 331 and an abutment block 332 are provided on the outer side of the abutment rod 330. The fourth connecting block 331 abuts against the third connecting block 322, wherein the rotating input rod 310 can drive the abutment rod 330 to rotate through the transmission rod 320, so as to drive the abutment block 332 to move to abut against the locking block 210.

[0039] It is understandable that the rotating input rod 310 can also drive the abutment rod 330 to rotate through the transmission rod 320 , so as to drive the abutment block 332 to move to release the abutment with the locking block 210 .

[0040] In some embodiments, the fourth connecting block 331 is rotatably connected to the third connecting block 322 .

[0041] In order to improve the abutment stability between the fourth connecting block 331 and the third connecting block 322, refer to Figure 3 The abutment rod 330 is sleeved with a first elastic member 410, one end of the first elastic member 410 is connected to the abutment rod 330, and the other end is connected to the base 100. The first elastic member 410 is used to drive the abutment rod 330 to rotate so that the fourth connection block 331 abuts against the third connection block 322. The first elastic member 410 can be set as a torsion spring or the like.

[0042] In this embodiment, refer to Figure 2 and Figure 3 A first positioning block 312 and a second positioning block 313 are provided on the outer side of the input rod 310, and a first limiting block 120 and a second limiting block 130 are provided on the base 100. The first limiting block 120 is located on the moving path of the first positioning block 312, and the second limiting block 130 is located on the moving path of the second positioning block 313.

[0043] When the input rod 310 rotates to make the abutting block 332 move to abut against the locking block 210 , the first positioning block 312 abuts against the first limiting block 120 to restrict the input rod 310 from further rotating.

[0044] When the input rod 310 rotates to make the abutting block 332 move to release the abutment with the locking block 210 , the second positioning block 313 abuts against the second limiting block 130 to limit the input rod 310 from further rotating.

[0045] Through the above structure, the first positioning block 312 , the second positioning block 313 , the first limiting block 120 and the second limiting block 130 can limit the rotation range of the input rod 310 .

[0046] The second connection block 321 is rotatably connected to the first connection block 311. For details, refer to Figure 3 The second connecting block 321 is provided with two connecting arms 321A, the two connecting arms 321A are arranged opposite to each other, and the connecting arms 321A are provided with a sliding hole 321A1.

The heating element 520 is set as an MCH heating plate; the hot stamping block 510 has a hot stamping pattern.

[0048] It is understandable that the pattern on the hot stamping block can be designed into date numbers, product logos, etc. according to user needs.

[0049] Through the above structure, the heating element 520 and the hot stamping block 510 clamp the packaging bag together to print the pattern on the hot stamping block onto the packaging bag.

[0050] The flip cover 200 is provided with a hot stamping block 510. For details, refer to Figure 1 and Figure 5 The flip cover 200 is provided with a mounting groove 220, the hot stamping block 510 is provided with an adsorbing member, a metal member 221 is provided at the bottom of the mounting groove 220, and the adsorbing member adsorbs the metal member 221, so that the hot stamping block 510 is installed in the mounting groove 220. The adsorbing member is a magnet; and the metal member 221 is a metal plate member that can be adsorbed by a magnet.

[0051] In some embodiments, the adsorption member may be disposed at the bottom of the mounting groove 220 , and the metal member 221 may be disposed at the hot stamping block 510 .

[0052] The bottom of the installation groove 220 is provided with a metal piece 221. Figure 5 The bottom of the installation groove 220 is provided with two installation posts (not shown in the figure), and the end of the installation post away from the bottom of the installation groove 220 is provided with an anti-dropping block (not shown in the figure), the metal part 221 is provided with two installation holes 221A, and the two installation posts are correspondingly penetrated through the two installation holes 221A, and the anti-dropping block is located on the side of the metal part 221 away from the bottom of the installation groove 220, and a second elastic member 420 is provided between the metal part 221 and the bottom of the installation groove 220, and the second elastic member 420 is used to drive the metal part 221 to move to abut against the anti-dropping block. The second elastic member 420 can be set as a spring or the like.

[0053] The above structure can reduce the probability of the bottom of the mounting groove 220 being damaged due to the collision of the stamping block 510 .

[0054] In this embodiment, refer to Figure 1 and Figure 2 The base 100 is provided with a accommodating chamber 140, and the accommodating chamber 140 is provided with the above-mentioned connecting rod assembly 300, the above-mentioned first limit block 120, the above-mentioned second limit block 130 and the functional device group 600.
