Now, let's look at the operation of the vacuum suction port 100 of the present invention configured as described above.

6A and 6B are schematic cross-sectional views illustrating an operation of adsorbing a vacuum suction port according to an exemplary embodiment of the present invention.

First, referring to “a”, in order to attach the vacuum suction port 100 of the present invention to the glass surface 200 or the tile wall surface, the user is brought into close contact with the suction plate 110 facing the glass surface 200.

Subsequently, referring to “I”, the user pushes the contact cover 140 toward the glass surface 200. Then, the curved inner surface and the first surface of the suction plate 110 are coupled to the end of the protrusion rod 144 of the close cover 140 due to the rise of the first packing member 150 that is in close contact with the third through hole 124. The air in the 2,3 through holes 112, 114, and 124 escapes to the outside, so that the adsorption plate 110 is vacuum-adsorbed to the glass surface 200. At this time, even if the restoring force of the elastic member 130 interposed between the close cover 140 and the cover 120 is not restored by the cover 120 which is vacuum-adsorbed to the glass surface 200, the cover ( 120 and the close cover 140 will be subjected to the force to open each other, because of this, the vacuum state inside is better, it will be able to maintain the adsorbed state more closely.

That is, the third through hole 124 has a stroke to sufficiently reciprocate the first packing member 150 attached to the protrusion rod 144 to realize a more perfect vacuum state, and at the same time By providing a force, even if there is a small amount of air inflow due to external factors, the internal volume changes to maintain the vacuum state.

On the other hand, in the vacuum adsorption process, one side of the cover, that is, the valve means 180 installed in the fourth through hole 126 is operated as follows.

That is, when the air inside the air is released to the outside due to the operation of the close cover 140, the air is partially introduced into the fourth through hole 126 through the second through hole 114 formed in the suction plate 110. Incoming pressure causes the cylinder 182 to be pushed back slightly. Then, the air is also discharged to the outside through the incision 128 formed in the upper portion, the cylinder 182 pushed backward when the discharge is completed is soon restored to the original state by the elastic force of the coil spring 188 to continue the fourth through The ball 126 is blocked.

Figure 7 is a schematic cross-sectional view showing the operation of the vacuum suction port is detached according to an embodiment of the present invention.

Referring to the drawings, when the vacuum suction hole 100 of the present invention is firmly adsorbed on the glass surface 200 as shown in FIG. 6, in order to separate it from the glass surface 200, a cover 120 to a close cover are usually used. It will be detachable only by holding 140 and pulling it strongly in the opposite direction.

However, the desorption method will not be easy if the adsorption plate 110 is firmly attached to the glass surface. Therefore, the present invention was provided with a valve means 180 to perform this desorption process more easily.

That is, when the handle 186 of the valve means 180 protruding into the cutout 128 of the cover 120 is pulled to the rear, the cylinder 182 will retreat in the fourth through hole 126. As a result, the second packing member 184 blocking the fourth through hole 126 will release the blockage. Therefore, the outside air is introduced into the adsorption surface through the cutout 128 and the fourth through hole 126 to easily release the vacuum state, thereby allowing the user to easily separate the vacuum suction port 100.

Therefore, according to the vacuum suction port 100 of the present invention, if the suction plate 110 is in close contact with the glass surface 200 or the tile wall surface and then push the close cover 140, the vacuum adsorption is very convenient, as well as the cover ( Since a sufficient stroke is secured inside the 120, the compressive force is excellent and the elastic member 130 is interposed between the cover 120 and the close cover 140, so that the tension is added and the vacuum state can be maintained for a long time.

In addition, the cover 120 is provided with a valve means 180 for introducing external air has an advantage that the vacuum is easy to remove and easier to remove.
