It is provided to inform you. Like reference numerals designate like elements in the drawings.

The vacuum valve body according to a preferred embodiment of the present invention has a simple structure and a small number of parts, is excellent in production and assembly, and can be easily adopted and used in various products for forming a vacuum.

Hereinafter, the present invention will be described in detail with reference to examples.

As shown in FIG. 1, the vacuum valve body 10 according to an embodiment of the present invention is provided in the vacuum forming unit 20 having an inner space, and receives vacuum pressure from a vacuum pressure supply means (not shown). It is for forming a vacuum in the inner space of the vacuum forming unit 20 and maintaining the vacuum state. The vacuum forming unit 20 includes all types of containers or plastic packs to form a vacuum therein, and for convenience of illustration, the related drawings are shown based on the case of application in the form of a container, for example.

2 and 3, the vacuum valve body 10 according to the embodiment of the present invention includes a housing 100, a valve fixture 200, a valve elastic body 300 and a valve support body 400. do.

First, the housing 100 is provided on the outer surface of the vacuum forming unit 20 so that a vacuum hose connected to a vacuum pressure supply means such as a vacuum pump can be easily attached or detached.

The housing 100 has an inner space and is formed in a shape through which the inside is penetrated, and as shown in FIG. 2, one end of the valve fixture 200 is a locking jaw to maintain a state caught on the inside of the housing 100. (110) is provided.

Next, the valve fixture 200 is inserted into the housing 100 so as to be caught by the locking jaw 110, and at least one communication hole 211 is provided to communicate with the inner space of the vacuum forming unit 20.

2 and 3, the valve fixing body 200 includes a valve fixing plate 210 provided with a communication hole 211 and a protrusion 220 protruding from one surface of the valve fixing plate 210. include Here, one side of the valve fixing plate 210 is caught on the locking jaw 110 and is fixed in the housing 100 by pressurization by the valve elastic body 300 and the valve support body 400 coupled to the housing 100. state can be maintained.

As shown in FIG. 2, the protruding portion 220 is tapered so that its cross-sectional area gradually decreases toward the protruding end, and the vacuum flow path 30 ) Close contact for closing or separation for forming the vacuum passage 30 can be made more smoothly. A detailed description related to this will be described later.

Next, the valve elastic body 300 is coupled to the valve fixture 200 in the housing 100, and is elastically deformed or restored depending on whether vacuum pressure is provided by a vacuum pressure supply means (not shown) to form a vacuum forming unit 20 The inner space of is opened or closed to the outside. Additionally, the valve elastic body 300 may be elastically deformed or restored depending on whether vacuum pressure is provided to open or close the communication hole 211 to the outside. In other words, when it is desired to form a vacuum inside the vacuum forming unit 20, the valve elastic body 300 is elastically deformed so that the air inside the vacuum forming unit 20 is discharged to the outside between the protrusions 220. After the flow path 30 is formed and a vacuum is formed inside the vacuum forming unit 20, when the vacuum pressure is to be maintained, the valve elastic body 300 elastically restores the vacuum flow path 30 to be closed.

When a vacuum is to be formed inside the vacuum forming unit 20, the valve elastic body 300 is elastically deformed to open the communication hole 211 by default. Conversely, when it is desired to maintain the vacuum pressure in a state in which a vacuum is formed inside the vacuum forming unit 20, the valve elastic body 300 may close the communication hole 211, but as will be described later, the vacuum passage forming elastic unit ( 320) may be in close contact with the outer surface of the protruding portion 220 to prevent the vacuum passage 30 from being generated. That is, in a state in which the vacuum flow-forming elastic part 320 is in close contact with the outer surface of the protruding part 220, the communication hole 211 is formed between the inner space of the vacuum forming part 20 and the valve elastic body 300, specifically, the protruding vacuum round. The inner empty space of the flow-forming elastic part 320 may have an open state to communicate with it. However, as described above, the vacuum flow forming elastic part 320 adheres to the outer surface of the protruding part 220, so that the internal vacuum pressure of the vacuum forming part 20 can be maintained.

As shown in FIGS. 2 and 3, the valve elastic body 300 includes a valve elastic plate 310, a vacuum passage forming elastic part 320, and a protruding end 330, and is made of silicone or rubber having more than normal elasticity. material can be made.

At least a portion of the valve elastic plate 310 is provided to be in contact with the valve fixing plate 210 so as to close the communication hole 211 .

In addition, the vacuum passage forming elastic part 320 is formed in a shape in which the protrusion 220 can be penetrated to form a vacuum passage 30 between the protrusion 220 when vacuum pressure is applied, and the valve elastic plate 310 It is made to protrude from one side. Here, the inner side of the vacuum passage forming elastic part 320 is made to penetrate so as to surround the protruding part 220 in the circumferential direction.

The protruding end portion 330 is provided to protrude in one direction along the edge of the valve elastic plate 310, and the shape deformation of the elastic portion 320 for forming a vacuum flow can be stably achieved by a contact structure with the valve support 400 described later. induce

Meanwhile, in the embodiment of the present invention, the protruding end 330 protrudes toward the valve support 400 to induce elastic deformation as described above by the contact structure with the valve support 400, but is not limited thereto.

For example, if it can be supported to enable elastic deformation of the vacuum flow forming elastic part 320 through a contact structure with the valve fixture 200, the protruding end 330 may protrude toward the valve fixture 200. .

Next, as shown in FIGS. 2 to 4, the valve support 400 is coupled to the housing 100, and elastic deformation of the valve elastic body 300 for opening or closing the communication hole 211 to the outside or One side of the valve elastic body 300 is supported so as to be restored. The valve support 400 may be fixed to the housing 100 through forced press fitting to fix the valve fixture 200 and the valve elastic body 300 in the housing 100 .

Specifically, the valve support 400 is provided with a contact support end 410 for contacting and supporting the inner surface of the protruding end 330 so that the protruding end 330 is interposed between the housing 100 and the inner surface.

That is, in a state where the valve support 400 is inserted into the housing 100, the outer surface of the contact support end 410 is in contact with the inner surface of the protruding end 330, and the protruding end 330 is in contact with the inner surface of the housing 100. It suppresses fine movement in the left and right directions between them.

In this way, since the protruding end 330 of the valve elastic body 300 is supported by the valve support 400, the elastic portion 320 for forming a vacuum passage elastically deforms when a vacuum pressure is applied, as will be described later, so that the gap between the protruding portion 220 and the protruding portion 220 A vacuum passage 30 may be formed and the communication hole 211 may be opened to the outside.

Meanwhile, a through hole 420 is provided in the valve support 400 so that vacuum pressure is supplied to the valve elastic body 300, and a vacuum pressure supply means (not shown) passes through the through hole 420 to the valve support 400 side. By providing an elastic deformation of the valve support 400 is induced.

As shown in FIG. 4, the present invention forms the vacuum passage 30 while the vacuum passage forming elastic part 320 spreads outward away from the protrusion 220 (cross-section expansion) and forms the communication hole 211. Through this, the vacuum pressure is transmitted into the vacuum forming unit 20.

In addition, as shown in FIG. 2, when the supply of vacuum pressure by the vacuum pressure supply means is released, the elastic part 320 for forming a vacuum passage elastically restores the direction approaching the protruding part 220, and accordingly, the protruding part 220 ) to close the vacuum passage 30 between the vacuum forming unit 20 so that the vacuum pressure is maintained.

Meanwhile, the present invention proposes an additional structure for more smoothly opening and closing the vacuum passage.

Specifically, as shown in FIGS. 2 and 4, the protruding portion 220 is tapered so that its cross-sectional area decreases toward the protruding end, and the elastic portion 320 for forming a vacuum passage is tapered to correspond to the protruding portion 220. it gets done In this way, as each component is tapered so that elastic deformation and restoration are more easily performed on its own, the protruding end of the elastic part 320 for forming a vacuum passage expands in a direction away from the protruding part 220 more easily when vacuum pressure is applied. The vacuum passage 30 may be formed, and conversely, when the vacuum pressure is released, the vacuum passage 30 may be prevented from being generated by being elastically restored quickly and in close contact with the outer surface of the protrusion 220 .

That is, the outer surface of the protruding part 220 and the inner surface of the elastic part 320 for forming a vacuum flow come into close contact with each other to suppress generation of a vacuum flow path, and the inner surface of the elastic part 320 for forming a vacuum flow path is spaced apart from the outer surface of the protruding part 220. A vacuum flow path is generated by elastically deforming to a certain extent, and as described above, as all related components are tapered, such elastic deformation and restoration can be performed more easily and quickly.

On the other hand, as shown in FIGS. 2 and 4, so that the elastic deformation and restoration of the above-described elastic part 320 for forming a vacuum passage is more easily performed, the elastic part for forming a vacuum passage 320 is a valve elastic plate 310 It is made so that the thickness gradually decreases towards the end spaced apart from.

Therefore, even if the vacuum pressure of the vacuum pressure supply means (not shown) is provided as low as a certain level or more, the vacuum passage forming elastic part 320 can be easily elastically deformed to form the vacuum passage 30, and the vacuum passage can be quickly removed when the vacuum pressure is removed. It is elastically restored to close the vacuum passage.

In addition, the present invention minimizes the mutual contact area between the valve fixing body 200 and the valve elastic body 300, and when the vacuum passage 30 is formed between the vacuum passage forming elastic part 320 and the protrusion 220, the vacuum forming part An additional structure is proposed so that the air in (20) is quickly discharged to the outside through the communication hole (211) and the vacuum passage (30). That is, a structure capable of quickly forming a vacuum inside the vacuum forming unit 20 is proposed.

Specifically, as shown in FIGS. 2 and 4 , the valve elastic plate 310 and the elastic part 320 forming a vacuum passage form a mutual relationship between the valve fixing plate 210 and the protrusion 220 regardless of whether vacuum pressure is provided or not. The connecting portion of the valve elastic plate 310 and the elastic portion 320 forming the vacuum passage is provided in a round shape so that the connecting portion is always non-contacting.

Here, when vacuum pressure is not provided, it is preferable that the valve elastic plate 310 closes the communication hole 211, and accordingly, after a vacuum is formed inside the vacuum forming unit 20, the communication hole 211 is closed and the protruding portion The vacuum state can be stably maintained by improving airtightness through a double sealing structure in which the vacuum passage is closed by close contact between the (220) and the elastic part 320 forming the vacuum passage.

On the other hand, when vacuum pressure is provided to form the vacuum passage 30 between the protruding portion 220 and the vacuum passage forming elastic portion 320, the valve elastic plate 310 is deformed to open the communication hole 211. And, as described above, since the connection portion between the valve elastic plate 310 and the vacuum flow path forming elastic part 320 is rounded, vacuum formation can be achieved through rapid exhaust.

Hereinafter, the operation relationship of the vacuum valve element according to the embodiment of the present invention will be described.

First, before vacuum pressure is supplied through a vacuum pressure supply means (not shown), as shown in FIG. By closing the communication hole 211, the formation of a vacuum flow path is not achieved.

Next, when vacuum pressure is provided through the vacuum pressure supply means, as shown in FIG. 4, the vacuum passage-forming elastic part 320 expands while being spread outward by the vacuum pressure, and accordingly, between the protrusions 220 As the vacuum passage 30 is formed, the closed state of the communication hole 211 is also released, so that the inner space of the vacuum forming unit 20 is opened to the outside through the communication hole 211 and the vacuum passage 30 . As the internal space of the vacuum forming unit 20 communicates with the outside in this way, the air inside the vacuum forming unit is discharged to the outside through the communication hole 211 and the vacuum flow path 30 sequentially by driving the vacuum pressure supply means. Thus, a vacuum state inside the vacuum forming unit may be achieved.

Next, when the supply of vacuum pressure through the vacuum pressure supply means is released, again as shown in FIG. 220 to limit the generation of a vacuum flow path, and similarly, the valve elastic plate 310 closes the communication hole 211.

Accordingly, the inside of the vacuum forming unit 20 can stably maintain a vacuum state by close contact between the protruding part 220 and the elastic part 320 forming a vacuum passage and closing the communication hole 211 .

The vacuum valve body according to an embodiment of the present invention has been described above, and the housing 100 for supporting one side of the protruding end 330 of the valve elastic body 300 can be omitted.

Specifically, in the above description, both side surfaces of the protruding end portion 330 are supported by being in contact with the inner surface of the housing 100 and the contact end portion 410 of the valve support 400, thereby elastically deforming the elastic portion 320 for forming a vacuum passage. , Restoration is induced. As shown in FIGS. 5 and 6 , the housing 100 can be omitted if the inner wall of the vacuum forming unit 20 performs the function of the housing 100 .

That is, by forming a separate insertion hole 21 in the vacuum forming unit 20 and sequentially inserting the valve fixing body 200, the valve elastic body 300 and the valve support body 400 into the insertion hole 21, In the same manner as the bar, it is possible to form a vacuum inside the vacuum forming unit and maintain the vacuum state.

In the above, the present invention has been shown and described in relation to preferred embodiments for illustrating the principles of the present invention, but the present invention is not limited to the configuration and operation as shown and described. Rather, it will be appreciated by those skilled in the art that many changes and modifications may be made to the present invention without departing from the spirit and scope of the appended claims.
