Valve positioning structure
A valve positioning structure is provided for pressing down a switch arranged in a valve so that fluid is allowed to flow through an inlet opening of the valve when the switch is pressed down in order to control the fluid to flow into/out of at least one bladder. The valve positioning structure includes a casing that receives the valve therein and the casing is provided with a contact member and a manipulation member respectively and movably on upper and lower surfaces of the casing. The contact member and the manipulation member are coupled to each other so that the contact member is operable to drive the manipulation member to move. The manipulation member includes an operation section, where the operation section is movable toward and is enabled to press down the switch when the manipulation member is driven by the contact member to move toward the switch.
1. A valve positioning structure for pressing down a switch arranged in a valve so that a fluid is allowed to flow through an inlet opening of the valve when the switch is pressed down in order to control the fluid to flow into/out of at least one bladder, comprising:
a casing receiving the valve therein;
a contact member movable on an upper surface of the casing in a first linear direction; and
a manipulation member movable on a lower surface of the casing, the contact member and the manipulation member being coupled to each other so that the contact member is operable to drive the manipulation member to move, when the manipulation member is driven by the contact member to move toward the switch, the manipulation member has a C-shaped portion with an opening at a side of the C-shaped portion configured to be moved in the first linear direction to receive the switch from the opening and to press down the switch in a second linear direction, substantially perpendicular to the first linear direction, to allow the fluid to flow through the valve, wherein the C-shaped portion has two side parts opposite to each other, between which the switch is received when the manipulation member is moved in the first linear direction toward the switch, wherein each of the side parts has a slope surface configured to move in the first direction over a flange of the switch radially protruding from an annular surface of the switch to press down the flange of the switch in the second linear direction.
2. The valve positioning structure of claim 1 , wherein the casing is provided with an inner space receiving the switch.
3. The valve positioning structure of claim 1 , wherein the casing is provided with a longitudinal guide hole therein, the contact member comprising a coupling element received in the longitudinal guide hole to have the contact member configured to be moved along the longitudinal guide hole in the first direction and to couple with the manipulation member, whereby the manipulation member is configured to be driven by the contact member to move along the longitudinal guide hole toward the switch in the first direction.
4. The valve positioning structure of claim 1 , wherein the casing is provided with multiple longitudinal through holes therein, the contact member comprising multiple guiding elements respectively received in the longitudinal through holes to move along the longitudinal through holes in the first direction.
5. The valve positioning structure of claim 1 , wherein the contact member comprises multiple projections thereon to have a finger touch and press the projections.
6. The valve positioning structure of claim 1 , wherein the contact member comprises a bearing section thereon to have a finger to contact and push the bearing section.
7. The valve positioning structure of claim 1 , wherein said each of the side parts has a horizontal surface extending from a free end thereof, wherein said each of the side parts has its slope surface sloped from its horizontal surface away from its free end.
8. The valve positioning structure of claim 7 , wherein the horizontal surface of said each of the side parts is configured to move in the first direction over the flange of the switch.
9. A valve comprising:
a switch; and
a manipulation member having a C-shaped portion with an opening at a side of the C-shaped portion configured to be moved in a first linear direction to receive the switch from the opening and to press down the switch in a second linear direction, substantially perpendicular to the first linear direction, to allow a fluid to flow through the valve, wherein the C-shaped portion has two side parts opposite to each other, between which the switch is received when the manipulation member is moved in the first linear direction toward the switch, wherein each of the side parts has a slope surface configured to move in the first direction over a flange of the switch radially protruding from an annular surface of the switch to press down the flange of the switch in the second linear direction.
10. The valve of claim 9 further comprising a contact member configured to drive the manipulation member, wherein the contact member comprises multiple projections thereon for having a finger touch and press the projections.
11. The valve of claim 9 further comprising a contact member configured to drive the manipulation member, wherein the contact member comprises a bearing section thereon to have a finger to contact and push the bearing section.
12. The valve of claim 9 , wherein said each of the side parts has a horizontal surface extending from a free end thereof, wherein said each of the side parts has its slope surface sloped from its horizontal surface away from its free end.
13. The valve of claim 12 , wherein the horizontal surface of said each of the side parts is configured to move in the first direction over the flange of the switch.
14. The valve of claim 9 further comprising a casing provided with an inner space receiving the switch.
15. The valve of claim 14 further comprising a contact member configured to drive the manipulation member, wherein the casing is provided with a longitudinal guide hole therein, wherein the contact member comprises a coupling element received in the longitudinal guide hole to have the contact member configured to be moved along the longitudinal guide hole in the first direction and to couple with the manipulation member, whereby the manipulation member is configured to be driven by the contact member to move along the longitudinal guide hole toward the switch in the first direction.
16. The valve of claim 14 further comprising a contact member configured to drive the manipulation member, wherein the casing is provided with multiple longitudinal through holes therein, wherein the contact member comprises multiple guiding elements respectively received in the longitudinal through holes to move along the longitudinal through holes in the first direction.
