Description
Technical Field
The invention relates to a supporting component, in particular to an air valve sucker.
Background
A wall climbing toy disclosed in taiwan patent No. TWI581844 comprises a sucker, an air inlet module communicated with the sucker, and an air valve module for controlling the air inlet module. When the sucker is extruded, the air in the sucker is discharged to be in a negative pressure state, so that the sucker is adsorbed on the wall surface. When the suction cup is to be desorbed, the air valve module controls the air inlet module to guide the external atmospheric pressure into the suction cup, so that the negative pressure state in the suction cup is destroyed to desorb the suction cup. However, in order to accomplish the foregoing, the air valve module and the suction cup must be in communication with each other through the air intake module. The air intake module is essentially a hose, which is easily entangled with other components, resulting in inconvenience.
Disclosure of Invention
The invention aims to provide an air valve sucker which is simple in structure and convenient to operate.
The air valve sucker is suitable for being adsorbed on a wall surface. The air valve sucker comprises a shell unit, a valve member and an absorbing member.
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 inwardly from the first tube body. The inner tube has a second tube body and at least one second extension wall extending outwardly from the second tube body. The first pipe body and the second pipe body are spaced 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 tube and the second tube. One end of the annular space is closed by at least one of the first extending wall and the second extending wall, and the other end is formed with an annular opening. The inner peripheral surface of the second pipe body is provided with a large-aperture section adjacent to the annular opening, a small-aperture section connected with the large-aperture section, and a first shoulder surface arranged between the large-aperture section and the small-aperture section. The inner diameter of the large aperture section is larger than the inner diameter of the small aperture section.
The valve member comprises a head adjacent to the small-bore section, a large-diameter rod portion protruding from the head and penetrating through the small-bore section, a small-diameter rod portion connected to the large-diameter rod portion, an abutting portion connected to the small-diameter rod portion, and a second shoulder surface arranged between the large-diameter rod portion and the small-diameter rod portion. The head has an outer diameter greater than an inner diameter of the small bore section. The outer diameter of the large rod diameter part is larger than that of the small rod diameter part. The outer diameter of the large rod diameter part is smaller than the inner diameter of the small-aperture section. The outer diameter of the abutting part is larger than that of the small rod diameter part. The abutment has a third shoulder surface adjacent the small stem diameter portion. The large aperture section, the first shoulder surface, the second shoulder surface and the small rod diameter portion together define an annular groove.
The absorbing member is made of a flexible material and includes a tube portion, a disk portion connected to one end of the tube portion, an extending portion extending inward from the tube portion, a first surrounding portion surrounding the small-diameter portion and protruding from the extending portion toward a side away from the disk portion, and a second surrounding portion surrounding the small-diameter portion and protruding from the extending portion toward a side adjacent to the disk portion. The end of the tube portion opposite the disc portion is embedded in the annular space by the annular opening. The first surrounding portion is embedded in the annular groove.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
Referring to fig. 1, 2 and 3, one embodiment of the suction cup of the air valve 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 body 111 and a first extension wall 112 extending inwardly from the first tube body 111. The first extension wall 112 has a radially inwardly extending radial segment 113 and an axially extending axial segment 114 connected to the radial segment 113. The inner tube 12 has a second tube body 121 and three second extension walls 122 extending outwardly from the second tube body 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. The first tube 111 and the second tube 121 define an annular space 13 therebetween. One end of the annular space 13 is closed by a radial section 113 of the first extension wall 112 and the other end is formed with an annular opening 131. The inner peripheral surface of the second tube 121 has a large aperture section 123 adjacent to the annular opening 131, a small aperture section 124 connected to the large aperture section 123, and a first shoulder 125 disposed between the large aperture section 123 and the small aperture section 124. The large bore section 123 has an inner diameter that is greater than the inner diameter of the small bore section 124.
It should be noted that, in the present embodiment, the second tube body 121 of the inner tube 12 is engaged with the axial section 114 in a tight fit manner, and the second extension wall 122 abuts against the radial section 113. Furthermore, in the present embodiment the annular space 13 is closed by a radial section 113 of the first extension wall 112. The benefit of this design is that it facilitates assembly, 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 may be enclosed by the second extending wall 122 or enclosed by the first extending wall 112 and the second extending wall 122 together, which is not limited thereto.
The valve member 2 includes a head 21 adjacent to the small bore section 124 and located outside the housing unit 1, a large stem diameter portion 22 protruding from the head 21 and penetrating through the small bore section 124, a small stem diameter portion 23 connected to the large stem diameter portion 22, an abutment portion 24 connected to the small stem diameter portion 23, and a second shoulder surface 25 disposed between the large stem diameter portion 22 and the small stem diameter portion 23. The outer diameter of the head 21 is greater than the inner diameter of the small bore section 124. The large rod diameter portion 22 has an outer diameter larger than that of the small rod diameter portion 23. The outer diameter of the large shank diameter portion 22 is less than the inner diameter of the small bore section 124. The abutment 24 has an outer diameter greater than that of the small-shank-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 bore section 123, the first shoulder 125, the second shoulder 25 and the small stem diameter 23 together define an annular groove 26.
In the present embodiment, the abutting portion 24 of the valve member 2 is substantially composed of a leakage stop cap 243 and a screw 244. The small shaft diameter portion 23 has a screw hole 231. The leakage stop cover 243 has the third shoulder surface 241 and the projection 242, and is provided to cover the small shaft diameter portion 23. The screw 244 passes through the leakage stop cap 243 and is locked into the screw hole 231 such that the leakage stop cap 243 is fixed to the small shaft diameter portion 23. In this way, the valve member 2 can be assembled. However, this structural design of splitting a single component into three independent components is merely an example, and one skilled in the art may also use other ways to complete the assembly, which should not be limited thereto.
It is further noted that in the present embodiment, the head 21 of the valve member 2 is completely exposed outside the housing unit 1, which is advantageous in that it is convenient for a user to operate the head 21. However, in other variations, only a portion of the head 21 may be exposed outside the housing unit 1, or hidden inside the housing unit 1 but not shielded, which 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 rod 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 rod 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 disc portion 32 is embedded in the annular space 13 by the annular opening 131. The first circumferential portion 34 is embedded in the annular groove 26. The second surrounding portion 35 abuts against the bump 242 of the abutting portion 24. The disc portion 32 and the wall 9 define a chamber S therebetween.
To adhere the present embodiment to 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 drives the housing unit 1 to press the adsorbing member 3 together, so that the disc portion 32 of the adsorbing member 3 is collapsed and deformed. At this time, the first surrounding portion 34 is tightly bonded to the second shoulder surface 25 to be airtight. The disc portion 32 collapses and deforms so that the gas in the chamber S is exhausted from the periphery of the disc portion 32, thereby adsorbing the adsorbing member 3 to the wall surface 9. In this way, the air in the chamber S is exhausted to a negative pressure state, so that the user can keep the adsorbing member 3 adsorbed on the wall surface 9 without continuously pressing the head 21.
It is further noted that the outer tube 11 also has a disc-shaped wall 115 arranged at one end adjacent to the disc-shaped portion 32. The disc wall 115 serves to conceal the disc portion 32 such that the disc portion 32 is protected from breakage and is aesthetically pleasing.
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 such that the head 21 is forced away from the wall 9, a gap is formed between the head 21 and the second tube 121 such that external air can permeate between the large stem diameter portion 22 and the small bore section 124. At this time, the extension portion 33 abuts against the second tube 121 and is not driven, so that a gap is formed between the first surrounding portion 34 and the second shoulder surface 25, and the external air permeates between the second surrounding portion 35 and the small rod diameter portion 23. Further, since the protrusions 242 are embossed on the third shoulder surface 241, the external air can permeate into the chamber S through the air channels between the protrusions 242, so that the air pressure in the chamber S returns to the same as the external air pressure and damages the negative pressure state. At this time, the disk portion 32 is restored and desorbed by its own flexibility.
It should be noted that, when the head 21 of the valve member 2 is forced away from the wall 9, the second surrounding portion 35 is pressed against the protrusion 242 to be in a compressed state. Therefore, when the head 21 is no longer stressed, the second surrounding portion 35 can push the abutting portion 24 to return to the direction away from the extending portion 33 by the elastic force of itself, and drive the head 21 to return to the position adjacent to the second tube 121, so as to absorb the embodiment to the surface of the wall 9 or other objects again.
In summary, according to the air valve sucker of the present invention, the structural relationship among the housing unit 1, the valve member 2 and the adsorbing member 3 enables a user to control whether the adsorbing function can be generated by pressing or pulling the head 21, and no additional fluid components such as hoses or air valves are needed, so that the structure is simplified effectively and the operation is easy, and the purpose of the present invention can be achieved.
