Technical Field

[0001] The utility model relates to the technical field of vacuum barrels, in particular to a vacuum unit and a vacuum barrel. Background Art

[0002] In today's society, storage containers have become an important part of our daily lives. In order to prevent items from getting damp, moldy or deteriorating, many businesses have introduced vacuum storage boxes, which greatly extend the shelf life of food and other items by extracting the internal air to create an oxygen-free environment. Currently, most vacuum storage boxes on the market use a design in which an exhaust device is installed on the sealing cover, which makes it easy to vacuum the inside of the storage box.

[0003] However, some existing vacuum storage boxes have certain limitations in the start and stop control of the vacuum unit. The vacuum pumps of these storage boxes are usually controlled only by a simple switch button, which may cause a problem in actual use: when the user opens the lid of the storage box, the vacuum pump may still be in operation, resulting in invalid actions, which not only increases the operating burden of the equipment, but also causes unnecessary waste of energy. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art that when the lid of the storage box is opened, the vacuum pump may still be in a working state, and a vacuum unit and a vacuum barrel are proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A trigger unit is also provided inside the shell, and the trigger unit is used to trigger the vacuum pump to stop working when the shell is tilted. A connection port is also electrically connected below the circuit board, and at least part of the connection port extends to the outside of the shell.

[0008] Furthermore, the trigger unit is a tilt sensor installed on the circuit board.

[0009] Furthermore, the shell includes an upper shell and a lower shell, and the upper shell and the lower shell are connected and fixed by a connecting component.

[0011] A connecting column is fixed on the inner side of the lower shell, a docking column matched with the connecting column is fixed on the inner side of the upper shell, and the connecting column and the docking column are connected via a locking piece.

[0012] Furthermore, the circuit board is electrically connected to a switch that penetrates the upper end of the shell, and the switch is used to control the start and stop of the vacuum pump. A power supply component is fixedly installed inside the shell, and the circuit board is electrically connected to the power supply component.

[0013] Furthermore, a resistance frame is fixed on the inner side of the upper shell, and a limiting opening adapted to the power supply assembly and the vacuum pump is opened on the lower side of the resistance frame.

[0014] The utility model also proposes a vacuum barrel, comprising a barrel body, a barrel cover and the above-mentioned vacuum unit;

[0015] A mounting groove is provided on the end surface of the barrel cover, the shell is installed in the mounting groove, and a one-way valve is also provided in the mounting groove.

[0016] Furthermore, a sensor is fixedly mounted on the inner side of the shell, and electrode columns penetrating the mounting grooves are fixedly mounted on two electrodes of the sensor, and the electrode columns are in contact with the connection port to achieve signal connection.

[0019] The utility model proposes a vacuum unit and a vacuum barrel, and the beneficial effect is that: in the utility model, a trigger unit is arranged inside the shell, which is used to keep the vacuum pump in a normal working state when the vacuum unit is placed horizontally. Specifically, when the barrel cover is closed on the barrel body, the vacuum operation can be carried out normally. When the barrel cover is opened, the trigger unit disconnects the circuit of the vacuum pump to stop the operation of the vacuum pump, thereby avoiding the problem that the vacuum pump is always in a working state when the cover is opened, causing the vacuum pump to be ineffective and causing energy loss.

In this embodiment, the power supply assembly 10 and the vacuum pump 2 both adopt a cylindrical structure design, so the limiting opening 122 is also adapted to be set as an arc-shaped opening, which is used to limit and fix the power supply assembly 10 and the vacuum pump 2 after the upper shell 12 and the lower shell 13 are fixed.

[0037] Reference Figure 4 , 5 In addition, the utility model also proposes a vacuum barrel, which specifically includes a barrel body 5, a barrel cover 6 and the above-mentioned vacuum unit;

[0038] A mounting groove 61 is provided on the end surface of the barrel cover 6, and the shell 1 is installed in the mounting groove 61. A one-way valve 62 is also provided in the mounting groove 61. The one-way valve 62 is used to be connected to the exhaust end of the vacuum pump 2 to achieve the effect of one-way gas path conduction.
