Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and more specifically to a knob-linked vacuum sealer with light rotation. Background Art

[0002] The vacuum sealer uses a vacuum pumping component to vacuum the vacuum packaging bag, and then uses a heat sealing component to heat seal the bag opening of the vacuum packaging bag to prevent the food in the vacuum packaging bag from oxidizing or deteriorating due to contact with air. It can effectively inhibit the growth of various bacteria and molds, thereby extending the shelf life.

[0003] Before sealing the packaging bag, the existing vacuum sealer needs to close the upper cover, turn on the power, release the pressure and other operations, and each step needs to be performed separately, which is quite troublesome and inconvenient. To this end, the applicant provides a knob-linked sealing machine with the authorization announcement number CN207157619U, which includes a main unit and an upper cover, the main unit is equipped with a shaft, a power-on mechanism, and a pressure-relief mechanism, a knob is installed on the outer side of the main unit, and a hook is installed on the side of the upper cover facing the main unit; the knob is connected to the shaft through a rotating mechanism for rotation control; the shaft is provided with a buckling part, and rotating the shaft can make the buckling part buckle on the hook and drive the upper cover to press on the main unit; the power-on mechanism corresponds to the position of the hook, and when the shaft is rotated to drive the upper cover to press on the main unit, the hook can trigger the power-on mechanism to complete the power-on; the shaft is also provided with a driving block at a position corresponding to the pressure-relief mechanism, and when the shaft is rotated to make the buckling part disengage from the hook, the driving block can trigger the pressure-relief mechanism to complete the pressure-relief. Therefore, this solution realizes the linkage between the power-on mechanism, the pressure relief mechanism and the upper cover. Only by turning the knob, the shaft can be easily driven to rotate, thereby completing the actions of opening the cover, powering on, and pressure relief without performing other operations.

[0004] However, after market research, it was found that the one-button multi-link knob transmission structure requires the shaft to simultaneously link and trigger multiple mechanisms, and in this solution, the knob and the shaft are only linked through the knob transmission block, which is equivalent to direct drive of the knob, making it more laborious for users to turn the knob, and the user experience is not ideal. Utility Model Content

[0005] The utility model aims to provide a knob-linked vacuum sealer with light rotation to solve the above problems.

[0006] The utility model adopts the following technical solutions:

[0011] Preferably, the swing block is a cam.

[0012] Furthermore, the main machine is provided with a silo for placing packaging bags, a cutter assembly for cutting packaging bags, a heating assembly for heat-sealing the bag opening of the packaging bags, and a vacuum assembly for evacuating the packaging bags.

When the user turns the knob, the driving gear of the gear transmission mechanism is driven to rotate. The driving gear, the transmission gear and the driven gear are meshed and transmitted in sequence, thereby amplifying the torque of the final driven gear. That is, when the user twists the knob, it can be more labor-saving and light, and the transmission is smoother and more stable.

[0016] 2. The knob of the utility model is rotated, which drives the shaft rod to rotate through the gear transmission mechanism and the rotating mechanism, thereby prompting the jade sleeve, the swing block and the hook to work together, triggering the power-on mechanism, the pressure relief mechanism and the upper cover locking, so that the opening and closing of the cover, power-on, pressure relief and other actions can be completed with one button, and the operation is simple and convenient.

[0017] 3. The cutter assembly of the utility model adopts a flip frame structure arranged under the upper cover. Compared with the existing vacuum sealer in which the cutter head is integrated in the upper cover, the position of the cutter head is closer to the packaging bag, making the cutting smoother and more labor-saving. In addition, the structure of the flip frame can also facilitate the maintenance of the cutter assembly. BRIEF DESCRIPTION OF THE DRAWINGS

Compared with the existing vacuum sealer in which the cutter head is integrated in the upper cover 20, the position of the cutter head is more in line with the packaging bag 90, making the cutting smoother and more labor-saving. In addition, the structure of the flip frame 31 can also facilitate the maintenance of the cutter assembly 30.

[0028] Reference Figures 3 to 5 The main unit 10 is provided with a shaft 12, an energizing mechanism 60 and a pressure relief mechanism 51. The shaft 12 is provided with a plurality of linkage members, which are respectively linked with the hook 21 of the upper cover 20, the energizing mechanism 60 and the pressure relief mechanism 51. The outer side of the main unit 10 is provided with a knob 13. One end of the shaft 12 is provided with a rotating mechanism 80 for driving the shaft 12 to rotate. The knob 13 is connected to the rotating mechanism 80 through a gear transmission mechanism 70. The pressure relief mechanism 51 is connected to the vacuum assembly 50, and the energizing mechanism 60 is respectively electrically connected to the heating assembly 40 and the vacuum assembly 50.

[0029] Specifically, refer to Figure 4 and Figure 5The rotating mechanism 80 includes a fixed plate 81, a rotating transmission block 82, a coupling block 83 and a rotating sleeve 84 fixedly installed in the main body 10.

When the shaft 12 is rotated to press the upper cover 20 onto the host 10, the hook 21 can be driven to be held in linkage with the power-on switch of the power-on mechanism 60 to complete the power-on.
