Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and examples.
Referring to fig. 1, 2 and 3, an embodiment of the suction cup of the present invention is adapted to be attached to a wall 9. The air valve sucker comprises a shell unit 1, a valve element 2 and an adsorption element 3.
Referring to fig. 2, 3 and 4, the housing unit 1 includes an outer tube 11 and an inner tube 12 fixed inside the outer tube 11. The outer tube 11 has a first tube 111 and a first extension wall 112 extending inwardly from the first tube 111. The first extension wall 112 has a radial section 113 extending radially inward, and an axial section 114 connected to the radial section 113 and extending axially. The inner tube 12 has a second tube 121 and three second extending walls 122 extending outwardly from the second tube 121. The first tube 111 and the second tube 121 are spaced apart from each other. The first extension wall 112 and the second extension wall 122 are connected to each other. An annular space 13 is defined between the first tube 111 and the second tube 121. One end of the annular space 13 is closed by the radial section 113 of the first extension wall 112, and the other end is formed with an annular opening 131. The inner circumferential surface of the second tube 121 has a large-diameter section 123 adjacent to the annular opening 131, a small-diameter section 124 connected to the large-diameter section 123, and a first shoulder 125 disposed between the large-diameter section 123 and the small-diameter section 124. The large diameter section 123 has an inner diameter larger than the small diameter section 124.
It should be noted that in the present embodiment, the second tube 121 of the inner tube 12 is tightly engaged with the axial segment 114, and the second extending wall 122 abuts against the radial segment 113. Furthermore, in the present embodiment the annular space 13 is closed by a radial section 113 of the first extension wall 112. The advantage of this design is that it is easy to assemble, however, in other variations, the inner tube 12 may have one, two or more than four second extension walls 122. Alternatively, the outer tube 11 and the inner tube 12 may be integrally formed. Furthermore, the annular space 13 can also be enclosed by the second extending wall 122 or enclosed by the first extending wall 112 and the second extending wall 122 together, which should not be limited thereto.
The valve member 2 includes a head 21 adjacent to the small diameter section 124 and located outside the housing unit 1, a large diameter portion 22 protruding from the head 21 and passing through the small diameter section 124, a small diameter portion 23 connected to the large diameter portion 22, an abutting portion 24 connected to the small diameter portion 23, and a second shoulder 25 disposed between the large diameter portion 22 and the small diameter portion 23. The outer diameter of the head 21 is larger than the inner diameter of the small aperture section 124. The large diameter portion 22 has an outer diameter larger than that 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 section 124. The abutting portion 24 has an outer diameter larger than that of the small 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 protruding from 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 the present embodiment, the abutting portion 24 of the valve element 2 is substantially composed of a leakage-stopping cover 243 and a screw 244. The small diameter portion 23 has a screw hole 231. The leakage-stopping cover 243 has the third shoulder surface 241 and the projection 242, and is covered on the small rod diameter portion 23. The screw 244 passes through the leakage stop cover 243 and is locked into the screw hole 231 so that the leakage stop cover 243 is fixed to the small shaft diameter portion 23. In this way, the valve element 2 can be completed in an assembled manner. However, this structure design of dividing a single component into three separate components is only an example, and those skilled in the art may also use other methods to complete the assembly, and should not be limited thereto.
It should be noted that in the present embodiment, the head 21 of the valve element 2 is completely exposed from the housing unit 1, which is advantageous in that the head 21 is convenient for the user to operate. However, in other variations, only a portion of the head 21 may be exposed outside the housing unit 1, or may be hidden inside the housing unit 1 but not shielded, and should not be limited thereto.
The adsorbing member 3 is made of a flexible material, and includes a tube portion 31, a disk portion 32 connected to one end of the tube portion 31, an extending portion 33 extending inward from the tube portion 31, a first surrounding portion 34 surrounding the small-diameter portion 23 and protruding from the extending portion 33 toward a side away from the disk portion 32, and a second surrounding portion 35 surrounding the small-diameter portion 23 and protruding from the extending portion 33 toward a side adjacent to the disk portion 32. The end of the tube portion 31 opposite the disk portion 32 is inserted into the annular space 13 through the annular opening 131. The first surrounding portion 34 is fitted into the annular groove 26. The second surrounding portion 35 abuts against the projection 242 of the abutting portion 24. The disc 32 and the wall 9 define a chamber S therebetween.
To attach the present embodiment to the wall surface 9, the user should press the head 21. When the user presses the head 21, the head 21 is forced to approach the wall 9, the head 21 drives the housing unit 1 to press the absorbing member 3 together, so that the disk portion 32 of the absorbing member 3 is deformed by collapsing. At this time, the first surrounding portion 34 and the second shoulder surface 25 are tightly attached to each other to form an airtight seal. The disk portion 32 is collapsed and deformed so that the gas in the chamber S is exhausted from the periphery of the disk portion 32, and the adsorbing member 3 is adsorbed on the wall surface 9. Thus, the gas in the chamber S is in a negative pressure state after being exhausted, and the user can keep the adsorbing member 3 adsorbed on the wall surface 9 without continuously pressing the head 21.
It is also noted that the outer tube 11 also has a dished wall 115 disposed adjacent one end of the dished portion 32. The dished wall 115 serves to shield the dished portion 32 so that the dished portion 32 is protected from breakage and is aesthetically pleasing.
Referring to fig. 5, to release the suction relationship between the present embodiment and the wall surface 9, the user should pull the head 21. When the user pulls the head 21 to force the head 21 away from the wall 9, a gap is formed between the head 21 and the second tube 121, so that the external gas can penetrate between the large diameter portion 22 and the small diameter portion 124. At this time, the extending portion 33 abuts against the second tube 121 and is not driven, so that a gap is also formed between the first surrounding portion 34 and the second shoulder surface 25, and external air permeates between the second surrounding portion 35 and the small-diameter portion 23. Further, since the protrusions 242 are embossed on the third shoulder surface 241, external air can permeate into the chamber S through the air passages between the protrusions 242, so that the pressure of the air in the chamber S is restored to the same level as the external air and the negative pressure is broken. At this time, the disk portion 32 is restored to its original shape by its own flexibility and the suction is released.
It should be noted that when the head 21 of the valve element 2 is forced away from the wall 9, the second surrounding portion 35 is pressed by the protrusion 242 to be compressed. Therefore, when the head portion 21 is not stressed any more, the second surrounding portion 35 can push the abutting portion 24 to return to the position away from the extending portion 33 by its own elastic force, and drive the head portion 21 to return to the position adjacent to the second tube 121, so as to adhere the embodiment to the surface of the wall surface 9 or other objects again.
In summary, according to the air valve suction cup of the present invention, through the structural relationship among the housing unit 1, the valve element 2 and the adsorbing element 3, the user can control whether the present embodiment can generate the adsorbing function only by pressing or pulling the head 21, without additional connection of fluid components such as a hose or an air valve, so as to effectively simplify the structure and facilitate the operation, thereby achieving the purpose of the present invention.
