The sensor is used to detect the current internal pressure of the barrel body 1. The vacuum pump is used to evacuate the inside of the barrel body 1. The circuit board is used as a control unit to electrically connect the vacuum pump and the sensor to achieve start-stop control. This method is a prior art and will not be described in detail here.

[0028] Furthermore, the barrel body 1 and the barrel cover 2 are connected and rotated via a connecting mechanism 4. Specifically, the barrel cover 2 described in this embodiment is a hollow structure. Of course, those skilled in the art know that a sealing ring can also be set on the bottom edge of the barrel cover to ensure the sealing of the connection between the barrel cover 2 and the barrel body 1.

[0029] A pressure relief mechanism 5 is further disposed inside the barrel cover 2 , and a control component 6 for driving the pressure relief mechanism 5 to move and relieve pressure is disposed outside the barrel cover 2 .

[0030] In some embodiments, the connecting mechanism 4 in the utility model is fixed to the shaft 42 on the side of the barrel cover 2 through a bracket 41. Preferably, two brackets 41 in this embodiment can be provided, and the shaft 42 is fixed between the two brackets 41;

[0031] A limiting component 43 and a stop component 44 are movably connected to the upper side of the barrel body 1 , and the shaft rod 42 is limited in the limiting component 43 and the stop component 44 .

[0032] On the basis of the above embodiment, the limiting component 43 includes an outer expansion edge 431 formed on the upper side of the barrel body 1, the cross section of the outer expansion edge 431 is an L-shaped structure, and a limiting portion 432 is further formed on the inner side of the outer expansion edge 431. Specifically, the limiting portion 432 described in this embodiment is set as a plate parallel to the vertical portion of the outer expansion edge 431;

[0033] A slide is formed between the outward expansion edge 431 and the limiting portion 432, and the slide runs through the lateral portion of the outward expansion edge 431. The stop component 44 slides in the slide. The top of the outward expansion edge 431 is also fixed with a stopping portion 433 facing the limiting portion 432, and the stopping portion 433 is perpendicular to the vertical portion of the outward expansion edge 431. Furthermore, in this embodiment, at least one arc plate is installed on the inner side of the stopping portion 433, and the arc plate is used to rotate with the shaft rod 42 by means of its arc surface to improve the rotation stability of the shaft rod 42, and the shaft rod 42 is stopped below the stopping portion 433.

[0034] Furthermore, in this embodiment, the stopping component 44 includes a stopping plate 441 that slides in the slideway. The stopping plate 441 is in a Z-shaped structure, and a top end thereof stops at a side edge of the locking portion 433 .

[0035] Of course, in order to realize the pressing and resetting of the stop plate 441, a connecting bottom plate 442 is also fixed to the bottom of the outer expansion edge 431 in this embodiment, and a first spring 443 is arranged between the connecting bottom plate 442 and the bending portion of the stop plate 441. Preferably, guide pillars are fixed to the bottom of the connecting bottom plate 442 and the bending surface of the stop plate 441, and the two ends of the first spring 443 are sleeved in the two guide pillars. In addition, the connecting bottom plate 442 in this embodiment is connected and fixed to the outer expansion edge 431 by bolts;

[0036] Among them, a limit block 444 for clamping the side of the connecting bottom plate 442 is fixed to the side of the stop plate 441. The limit block 444 is used to limit the downward sliding distance of the stop plate 441 to avoid invalid operation of the stop plate 441 and improve the unlocking effect.

[0037] When disassembling the barrel cover 2, firstly, the pressure inside the barrel body 1 is relieved through the pressure relief mechanism 5. At this time, the barrel cover 2 can be rotated to open, and then the stop plate 441 is pulled downward. When the stop plate 441 slides downward until its top side is separated from the side of the locking portion 433, the locking portion 433 is in an unobstructed opening state. In this state, the barrel cover 2 can be pulled and moved to make the shaft rod 42 on the barrel cover 2 slide out along the above-mentioned opening, and the disassembly of the barrel cover 2 can be completed. The operation is simple and convenient, and the barrel body 1 and the barrel cover 2 can be conveniently separated to improve the convenience of subsequent inspection and maintenance.

[0038] In some embodiments, the pressure relief mechanism 5 in the utility model includes a pressure relief hole 51 opened on the hollow bottom surface of the barrel cover 2, a sealing gasket 52 above the pressure relief hole 51, a guide frame 53 is fixed to the hollow inner side of the barrel cover 2, and a plug rod 54 is movably inserted into the inner side of the guide frame 53. A second spring 55 is connected between the plug rod 54 and the guide frame 53, and the sealing gasket 52 is fixed to the bottom of the plug rod 54, that is, in the initial rotation state, the spring resists the plug rod 54 to move it downward, so as to keep the sealing gasket 52 tightly fitted above the pressure relief hole 51 to achieve sealing. When relieving pressure, it is only necessary to move the plug rod 54 upward, and the plug rod 54 drives the sealing gasket 52 to move upward. At this time, the pressure relief hole 51 is opened to complete the pressure relief operation.

[0039] On the basis of the above-mentioned embodiment, the control component 6 in this embodiment includes a swing arm 61 rotatably connected to the inside of the barrel cover 2, and one end of the swing arm 61 extends to the outside of the barrel cover 2, that is, a movable opening should be opened on the side of the barrel cover 2, and a part of the swing arm 61 can swing in the movable opening, wherein the middle part of the swing arm 61 has a connecting arm 62, and the connecting arm 62 is pin-connected with the insertion rod 54 to drive the insertion rod 54 to move.

[0040] It should be pointed out that the connecting arm 62 and the insertion rod 54 described in this embodiment are both provided with pin holes, wherein the pin hole on the connecting arm 62 can be set as a straight slot hole to meet the arc trajectory of its swinging to adapt to the up and down movement trajectory of the insertion rod 54, and the pin can be riveted and fixed to the pin hole of the insertion rod 54 to meet the requirements of driving stability.

[0041] In addition, the inner bottom of the barrel cover 2 in this embodiment is provided with two buckling grooves 21, in which a brush and tableware are respectively buckled. Specifically, in this embodiment, by designing the brush and tableware built into the bottom of the barrel cover 2, the tableware can be conveniently carried as a whole. In addition, the brush can be used to clean the top opening of the barrel body 1 to avoid dust accumulation at the opening of the barrel body 1, which makes it inconvenient to clean.

[0042] In summary, the utility model adopts the design of the connecting mechanism 4 to maintain the connection and rotation requirements between the barrel cover 2 and the barrel body 1, and at the same time can realize the detachable function of the barrel cover 2 and the barrel body 1. The disassembly method is simple. Only the stop plate 441 needs to be pulled down to pull and move the barrel cover 2 for disassembly. The operation is simple and convenient, and the barrel body 1 and the barrel cover 2 can be easily separated to improve the convenience of subsequent inspection and maintenance. In addition, a swingable pressure relief mechanism 5 is also designed. The swinging structure saves effort during pressure relief operation, which further optimizes the convenience of operation.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
