Abstract

An air valve suction cup comprises a housing unit, a valve set on the housing unit, and an adsorption part installed on the housing unit. The valve comprises a head part, a large rod diameter part, a small rod diameter part, and a second shoulder plane. The adsorption part comprises a tube part, a dish part connected to the tube part, and a first surround part disposed in the tube part. When the valve is pressed, the first surround part is tightly fitted with the second shoulder plane to become airtight and the dish part collapses and deforms so that the adsorption part is adsorbed on the wall surface. When the valve is pulled, a gap is formed between the first surround part and the second shoulder plane so that the dish part is restored to its original shape and the adsorption is released. This invention only needs to press or pull the head part of the valve to control whether to adsorb or not, thereby generating the effects of simple structure and convenient operation.

Description

Air valve suction cup

The present invention relates to a support assembly, in particular to an air valve suction cup.

A wall-climbing toy disclosed in Taiwan Patent No. I581844 includes a suction cup, an air intake module communicated with the suction cup, and an air valve module for controlling the air intake module. When the suction cup is squeezed, the gas in the suction cup is discharged to be in a negative pressure state, so that the suction cup is adsorbed on the wall surface. When the adsorption is to be released, the air intake module is controlled by the air valve module to introduce the external atmospheric pressure into the suction cup, so that the negative pressure state in the suction cup is destroyed and the adsorption is released. However, in order to complete the aforementioned actions, the air valve module and the suction cup must be communicated with the air intake module. The air intake module is essentially a hose, which is easily entangled with other components, causing inconvenience.

Therefore, the object of the present invention is to provide a valve suction cup with a simple structure and easy operation.

Therefore, the valve suction cup of the present invention is suitable for being adsorbed on a wall surface. The air valve suction cup includes a housing unit, a valve part, and an adsorption part.

The housing unit includes an outer tube and an inner tube fixed inside the outer tube. The outer tube has a first tube body and a first extension wall extending inward from the first tube body. The inner tube has a second tube body and at least one second extension wall extending outward from the second tube body. The first tube body and the second tube body are spaced apart from each other, and the first extension wall and the second extension wall are connected to each other. An annular space is defined between the first pipe body and the second pipe body. One end of the annular space is closed by at least one of the first extension wall and the second extension wall, and has an annular opening disposed at the other end. The inner peripheral surface of the second pipe body has a large-aperture section adjacent to the annular opening, a small-aperture section connected to the large-aperture section, and a third-diameter section disposed between the large-aperture section and the small-aperture section One shoulder. The inner diameter of the large aperture section is larger than the inner diameter of the small aperture section.

The valve member includes a head adjacent to the small aperture section, a large rod diameter portion protruding from the head and passing through the small aperture section, and a small rod diameter portion connected to the large rod diameter section , a contact part connected to the small rod diameter part, and a second shoulder surface arranged between the large rod diameter part and the small rod diameter part. The outer diameter of the head is larger than the inner diameter of the small aperture segment. The outer diameter of the large rod diameter portion is larger than the outer diameter of the small rod diameter portion. The outer diameter of the large diameter portion is smaller than the inner diameter of the small diameter section. The outer diameter of the abutting portion is larger than the outer diameter of the small rod diameter portion. The abutting portion has a third shoulder surface adjacent to the small diameter portion. The large diameter section, the first shoulder surface, the second shoulder surface and the small diameter portion together define an annular groove.

The adsorbent is made of flexible material, and includes a tube portion, a dish-shaped portion connected to one end of the tube portion, an extension portion extending inward from the tube portion, a portion surrounding the small rod diameter and extending inwardly. A first surrounding portion protruding from the extension portion toward a side away from the dish-shaped portion, and a first surrounding portion surrounding the small rod diameter portion and protruding from the extension portion toward a side adjacent to the dish-shaped portion Two surrounds. One end of the tube portion opposite to the dish-shaped portion is inserted into the annular space through the annular opening. The first surrounding portion is embedded in the annular groove. The second surrounding portion abuts against the abutting portion. A cavity is defined between the dish-shaped portion and the wall.

When the head of the valve member is forced to approach the wall surface, the first surrounding portion and the second shoulder surface are closely fitted to be airtight, and the disc-shaped portion collapses and deforms so that the gas in the chamber is released from the disc. The peripheral edge of the shaped portion is discharged, so that the adsorption member is adsorbed on the wall surface. When the head of the valve member is forced to move away from the wall, a gap is formed between the first surrounding portion and the second shoulder surface, and external gas penetrates into the chamber through the gap, thereby restoring the dish-shaped portion Undisturbed and desorbed.

The effect of the present invention is that the adsorption relationship between the adsorption member and the wall surface is controlled by whether the first surrounding portion and the second shoulder surface are airtight or not, and the valve member only needs to be pressed or pulled. The head can be achieved without connecting other gas pipelines, resulting in the effect of simple structure and easy operation.

The outer diameter of the head 21 is larger than the inner diameter of the small aperture section 124 . The outer diameter of the large diameter portion 22 is larger than the outer diameter of the small diameter portion 23 . The outer diameter of the large diameter portion 22 is smaller than the inner diameter of the small diameter portion 124 . The outer diameter of the abutting portion 24 is larger than the outer diameter of the small rod diameter portion 23 . The abutting portion 24 has a third shoulder surface 241 adjacent to the small diameter portion 23 , and a plurality of protrusions 242 embossed by the third shoulder surface 241 . The large diameter section 123 , the first shoulder surface 125 , the second shoulder surface 25 and the small diameter portion 23 together define an annular groove 26 .

It should be noted that, in this embodiment, the abutting portion 24 of the valve member 2 is substantially constituted by a leak-proof cover 243 and a screw 244 . The small diameter portion 23 has a screw hole. The leak-proof cover 243 has the third shoulder surface 241 and the protruding blocks 242 and covers the small diameter portion 23 . The screw 244 passes through the leak-proof cover 243 and is locked into the screw hole so that the leak-proof cover 243 is fixed to the small rod diameter portion 23 . In this way, the valve member 2 can be completed in an assembled manner. However, this structural design of splitting a single element into three independent elements is only an example, and those skilled in the art may also use other ways to complete the assembly, which should not be limited thereto.

It should also be noted that, in this embodiment, the head 21 of the valve member 2 is completely exposed outside the housing unit 1 , and the advantage of this design is that it is convenient for the user to operate the head 21 . However, in other variation examples, only a part of the head 21 may be exposed outside the housing unit 1 , or hidden in the housing unit 1 but not covered, which should not be limited thereto.

The adsorption member 3 is made of flexible material, and includes a pipe portion 31 , a dish-shaped portion 32 connected to one end of the pipe portion 31 , an extension portion 33 extending inward from the pipe portion 31 , a surrounding The small diameter portion 23 and a first surrounding portion 34 protruding from the extending portion 33 toward the side away from the dish portion 32 , and a first surrounding portion 34 surrounding the small diameter portion 23 and extending from the extending portion 33 toward the adjacent A second surrounding portion 35 protrudes from one side of the dish-shaped portion 32 . One end of the tube portion 31 opposite to the dish portion 32 is inserted into the annular space 13 through the annular opening 131 . The first surrounding portion 34 is inserted into the annular groove 26 . The second surrounding portion 35 abuts against the abutting portion 24 . A cavity S is defined between the dish-shaped portion 32 and the wall surface 9 .

To adsorb the present embodiment on the wall 9 , the user should press the head 21 . When the user presses the head 21 so that the head 21 is forced to approach the wall 9 , the head 21 will drive the housing unit 1 to squeeze the suction member 3 together, so that the suction member 3 has a dish-shaped shape. The portion 32 is collapsed and deformed. At this time, the first surrounding portion 34 is tightly fitted with the second shoulder surface 25 to be airtight. The dish-shaped portion 32 is collapsed and deformed, so that the gas in the chamber S is discharged from the periphery of the dish-shaped portion 32 , so that the adsorption member 3 is adsorbed on the wall surface 9 . In this way, the gas in the chamber S will be in a negative pressure state after being discharged, and the user does not need to continuously press the head 21 to keep the adsorption member 3 adsorbed on the wall surface 9 .

It should also be noted that the outer tube 11 also has a dish-shaped wall 115 disposed adjacent to one end of the dish-shaped portion 32 . The dish-shaped wall 115 is used for shielding the dish-shaped portion 32 , so that the dish-shaped portion 32 is protected from damage and more beautiful.

Referring to FIG. 5 , in order to release the adsorption relationship between the present embodiment and the wall surface 9 , the user should pull the head 21 . When the user pulls the head 21, so that the head 21 is forced away from the wall surface 9, a gap is formed between the head 21 and the second pipe body 121, so that the external gas can penetrate into the large rod diameter between the portion 22 and the small aperture section 124 . At this time, the extension portion 33 abuts against the second pipe body 121 and will not be driven, resulting in a gap between the first surrounding portion 34 and the second shoulder surface 25 , so that external gas penetrates into the second pipe body 121 . between the surrounding portion 35 and the small diameter portion 23 . Furthermore, since the bumps 242 are embossed on the third shoulder surface 241 , external gas can penetrate into the chamber S through the gas passages between the bumps 242 , thereby causing the inside of the cavity S The gas pressure returns to the same as the outside and destroys the negative pressure state. At this time, the dish-shaped portion 32 will return to its original state and release adsorption by its own flexibility.

It is worth mentioning that when the head 21 of the valve member 2 is forced away from the wall surface 9 , the second surrounding portion 35 is pressed against by the projections 242 and is in a compressed state. Therefore, when the head 21 is no longer stressed, the second surrounding portion 35 can push and reset the abutting portion 24 away from the extending portion 33 by its own elastic force, and drive the head 21 returns to the position adjacent to the second pipe body 121, so as to adsorb the present embodiment on the wall surface 9 or the surface of other objects again.

To sum up, the air valve suction cup of the present invention, through the structural relationship between the housing unit 1 , the valve member 2 and the suction member 3 , allows the user to control the embodiment only by pressing or pulling the head 21 . For example, whether the adsorption function can be generated, there is no need to connect additional fluid components such as hoses or air valves, the structure is effectively simplified and the operation is easy, so the purpose of the present invention can be achieved.

However, the above are only examples of the present invention, and should not limit the scope of implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the present invention. within the scope of the invention patent.
