Description

Technical Field

[0001] This utility model relates to a vacuum sealing machine, and more particularly to an electric vacuum sealing machine. Background Technology

[0002] Existing vacuum sealing machines are powered by either built-in batteries or external power supplies. External power supplies have higher power and better vacuuming effect, but the power cord connector is a straight line, so the power cord must be unplugged when storing the machine. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a plug-in vacuum sealing machine, wherein the power cord is snapped into the wire slot and can be stored together with the vacuum sealing machine, and the L-shaped connector is kept in contact with the plug.

[0009] In this design, the cable tray is located on the back of the first cover, and the tray is long enough to accommodate the folded power cord.

[0010] Preferably, the connector has a plug end and a wire end, the plug end extending longitudinally and the wire end extending laterally.

[0011] This design ensures that the connection between the power cord and the connector will not be bent during storage.

[0012] Preferably, the first cover includes a housing and a wire-locking block, the wire-locking block is inserted into the housing, the wire-locking block is provided with a portion of the wire-locking groove and the locking block, and the housing is provided with an installation opening for the wire-locking block to be exposed.

[0013] In this design, the first cover and the wire slot are designed separately, which reduces the processing difficulty of the card block.

[0014] Preferably, the wire-locking block has a curved surface, and the wire-locking groove is provided on the curved surface.

[0015] In this solution, a wire-clamping groove is machined on the curved surface at the wire-clamping block, reducing the machining difficulty of the wire-clamping groove.

[0016] Preferably, the first cover body is provided with a circuit board and an air pump, the circuit board is electrically connected to the socket, the air pump is controlled by the circuit board, and the top surface of the first cover body is provided with a display screen, which is signal connected to the circuit board.

[0017] In this solution, the display screen provides functions such as working mode selection and temperature display.

[0018] Preferably, the bottom surface of the first cover is provided with an opening, and a surrounding plate is provided at the opening. The surrounding plate is provided with a locking block and a vent. The vent is connected to the air outlet of the air pump. The second cover is provided with a protrusion corresponding to the opening, and the protrusion is provided with a groove corresponding to the locking block.

[0019] In this design, the protrusion extends into the opening, and the locking block engages with the slot to lock the first cover and the second cover. The air pump releases air from the opening through the vent.

[0020] The beneficial effects of this utility model are that it eliminates the need to change the orientation of the plug; during storage, the L-shaped connector maintains the connection between the power cord and the plug, and the power cord is snapped into the cable retainer slot; the spaced retaining blocks limit the power cord's position, ensuring effective locking while making the power cord easy to remove. Therefore, this utility model has substantial features and advancements compared to existing technologies. Attached Figure Description

[0033] See appendix Figure 1-7 In one embodiment of this invention, a plug-in vacuum sealing machine includes a first cover 1 and a second cover 2 that cooperate with each other, and the first cover 1 is connected to a power cord 3.

[0034] The first cover 1 is provided with a socket 4, and the power cord 3 is connected to a connector 5. The connector 5 is L-shaped and has a plug end 9 and a connecting end 10. The plug end 9 extends longitudinally, and the connecting end 10 extends laterally. The connector 5 is plugged into the socket 4. The first cover 1 is provided with a connecting groove 6 and a wire-holding groove 7. The connecting groove 6 is for the connector 5 to be embedded, and the wire-holding groove 7 is for the power cord 3 to be accommodated. The wire-holding groove 7 is provided with spaced-apart locking blocks 8, which limit the position of the power cord 3. The first cover 1 is approximately cuboid, and the socket 4, the connecting groove 6, and the wire-holding groove 7 are provided with... On the back of the first cover 1, a circuit board 14 and an air pump 15 are provided inside the first cover 1. The circuit board 14 is electrically connected to the socket 4, and the air pump 15 is controlled to the circuit board 14. A display screen 16 is provided on the top surface of the first cover 1. The display screen 16 is signal connected to the circuit board 14. An opening 17 is provided on the bottom surface of the first cover 1. A surrounding plate 18 is provided at the opening 17. A locking block 19 and an air vent are provided on the surrounding plate 18. The air vent is connected to the air outlet of the air pump 15. The second cover 2 is provided with a protrusion 20 corresponding to the opening 17. The protrusion 20 is provided with a slot 21 corresponding to the locking block 19.

[0035] In this embodiment, during operation, the power cord 3 is unfolded (the power cord 3 in the figure is in the unfolded state, and there is no need to plug or unplug the connector 5), the power cord 3 is connected to the mains power, the protrusion 20 extends into the opening 17, and the locking block 19 is engaged in the slot 21 to complete the locking of the first cover 1 and the second cover 2. The air pump 15 draws in air to create a vacuum, and after vacuuming, the opening is heated and sealed. This is a mature technology. The air pump 15 releases air through the vent of the enclosure plate 18. When storing, the power cord 3 is folded and engaged in the wire-locking groove 7. The bottom surface of the locking block 19 and the top surface of the protrusion 20 are provided with matching inclined surfaces. Both deform to allow the locking block 19 to engage in the slot 21, and the locking is natural. The wire-locking groove 7 can limit the power cord 3 by increasing the friction between the power cord 3 and the wire-locking groove 7 due to its own elasticity, or the locking block 8 can prevent the power cord 3 from leaving the wire-locking groove 7. The deformation of the power cord 3 under external force can overcome the limitation of the locking block 8.

[0036] In other alternative embodiments, a vent can be provided on the side of the first cover 1 for venting, and the locking method is varied and not limited to this.

[0037] See appendix Figure 1-3 The first cover 1 includes a housing 11 and a wire-locking block 12. The wire-locking block 12 is inserted into the housing 11. The wire-locking block 12 is provided with a portion of the wire-locking groove 7 and the locking block 8. The housing 11 is provided with an installation opening for the wire-locking block 12 to be exposed. The wire-locking block 12 has a curved surface 13, and the wire-locking groove 7 is provided on the curved surface 13.

[0038] In this embodiment, two sections of wire-locking groove 7 are cut and set onto a separate wire-locking block 12. A set of locking blocks 8 is set on the edge of each section of wire-locking groove 7. One section of wire-locking groove 7 is set on the curved surface 13, and the other section is set on the flat surface.

[0039] The above description represents the preferred embodiment of this utility model. It should be noted that the scope of protection of this utility model is not limited thereto. For those skilled in the art, various improvements, modifications, or equivalent substitutions can be made without departing from the equivalent inventive concept disclosed in this utility model, and these can also be considered as part of the scope of protection of this utility model.
