Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined to clearly and completely describe the technical solutions of the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1-5, an evacuated sealing device includes: the outer sealing cover body 1 is covered on the outer peripheral surface of the object A to be pumped, and a sealed cavity is formed between the outer sealing cover body 1 and the object A to be pumped; the sealing ring 2 is fixed on the inner side of the outer sealing cover body 1 and is attached to the object A to be pumped; the outer sealing cover body 1 is connected with a vacuum machine 4 through a circulating pipe 3.

In traditional domestic sealed jar of body, often utilize the apron to cover earlier and establish on jar opening of body, screw the thread cover on the apron again, make the apron can be tightly give down the opening, more to seal assembly's requirement, simultaneously, still need to seal and set up the screw thread on the jar body, holistic cost has also increased.

In this embodiment, the object a to be drawn is a tank or a bottle.

So in order to reduce the cost, also reduce the step when the sealed jar body simultaneously, the utility model discloses in, only need ordinary jar body or bottle, it only needs one to be greater than open-ended apron to go up, be in the state of horizontal laminating between apron and the opening, when using, shield the apron in the bottleneck, establish the opening part of jar body or bottle with external sealed cover body 1 cover, form airtight cavity between external sealed cover body 1 and jar body or the bottle, then start vacuum machine 4, vacuum machine 4 extracts the gas in the airtight cavity through runner pipe 3, and extract the gas in jar body or the bottle through the gap between apron and jar body or the bottle, close vacuum machine 4 again, take off external sealed cover body 1, the outside atmospheric pressure of jar body or bottle is greater than jar body or the inside atmospheric pressure of bottle this moment, with the tight bottleneck department at jar body or bottle of pressing of apron, reach sealed effect, and when needing to open, only need to dig the apron with hand or instrument can, need not to rotate, the work that compresses tightly, sealed and dismantlement process is all comparatively simple.

In fact, the external sealing cover body 1 only needs to cooperate with the sealing ring 2 to form a closed cavity, but in order to improve the sealing effect, in this embodiment, the external sealing cover body 1 includes: the first sealing cover 11 covers the outer side of the object A to be extracted; the device comprises a first sealing cover 11, a second sealing cover 12 connected to the first sealing cover 11 and abutted against a cover plate of the object A to be extracted, and a third sealing cover 13 connected to the second sealing cover 12 and communicated with the circulating tube 3, wherein the first sealing cover 11 has the functions of attaching and covering the object A to be extracted, the specific covering position can be a bottle body, a bottle neck and the like of the object A to be extracted, a closed cavity is formed by matching with the sealing ring 2, the second sealing cover 12 has the function of pressing the cover plate of the object A to be extracted to tightly press the cover plate at the bottle mouth of the object A to be extracted to provide a certain foundation for the vacuum-extracting action in the object A to be extracted, and the third sealing cover 13 has the function of communicating with the circulating tube 3 and is properly matched with the circulating tube 3 to achieve an airtight state after the assembly is completed.

However, if the inner side surface of the whole second sealing cover 12 is pressed, the channel between the first sealing cover 11 and the third sealing cover 13 is easily blocked, so that the whole vacuumizing operation cannot be performed, therefore, a plurality of pressing blocks 121 are uniformly arranged on the inner side of the second sealing cover 12 at equal intervals, the pressing blocks 121 are pressed on the cover plate a to-be-pumped, the cover plate a to-be-pumped can be pressed by the pressing blocks 121, and meanwhile, the channel between the first sealing cover 11 and the third sealing cover 13 can be communicated, so that a certain pressing effect is achieved, and the vacuumizing operation is not hindered.

In other embodiments, due to the different calibers of different bottles or tanks, the calibers of the corresponding outer sealing cover body 1 and the corresponding sealing ring 2 are also changed adaptively.

Due to possible caliber change, the pressing block 121 is not necessarily accurately arranged, and under the condition of inaccurate arrangement, one side of the cover plate may not be pressed by the pressing block 121, so in order to balance the pressing force of each side, a soft cushion (not shown in the figure) is arranged on one side of the pressing block 121 close to the circle center, the soft cushion is pressed against the cover plate of the object a to be extracted, and when errors occur in processing so that the pressing block 121 cannot be pressed to the cover plate, the soft cushion can be used for complementing, and the pressures of all contact points are the same.

In the present embodiment, the number of the pressing pieces 121 and the cushion is three, but in other embodiments, the number of the pressing pieces and the cushion is not limited as long as the pressing pieces and the cushion are uniformly arranged in a ring shape at equal intervals.

In the process of communicating the third sealing cover 13 with the vacuum machine 4, in order to ensure rapid and stable vacuum pumping, the connection sealing performance between the third sealing cover 13 and the vacuum machine is very important, so the third sealing cover 13 is provided with the circulation port 131, the circulation pipe 3 comprises a connection head 31, the connection head 31 is matched with the circulation port 131, wherein the connection head 31 is a rigid connection head, the connection head is also in rigid matching with the circulation port 131, no gap exists between the connection head and the circulation port 131 after connection, and the connection is tight, so that the matching degree of the connection head and the circulation port is improved, and the vacuum pumping efficiency is improved.

In this embodiment, the circulation pipe 3 may be directly connected to the vacuum machine 4 or may be connected to the vacuum machine 4 through a relay B, and if the circulation pipe 3 is directly connected to the vacuum machine 4, the connection head 31 is also required to be provided on the other side of the circulation pipe 3, and if the relay B is used, the relay B is not required to be provided on the other side of the circulation pipe 3.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
