As shown in fig. 7-12, the vacuum pump 122 includes a first cover 1221, a second cover 1222, a first sealing member 1223, and eight resilient members 1224. The second cover 1222 is disposed on the first cover 1221 and is movable between a first position and a second position relative to the first cover 1221. The first sealing member 1223 is disposed between the first cover 1221 and the second cover 1222 to prevent fluid from leaking from a gap between the first cover 1221 and the second cover 1222. The second cover 1222 is formed with a suction port 1222A, and the suction port 1222A has a suction communication passage 1222B. The first cap 1221 is formed with a discharge port 1221A, and the discharge port 1221A has a discharge communication passage 1221B. When the second cover 1222 is in a first position relative to the first cover 1221, as shown in fig. 9, a chamber 1225 is formed between the first cover 1221 and the second cover 1222. During the movement of the second cap 1222 relative to the first cap 1221, the volume of the chamber 1225, i.e. the available fluid volume, changes. When the second cap 1222 is moved downward relative to the first cap 1221 from the first position to the second position, the chamber 1225 is compressed to force fluid (e.g., air) within the chamber 1225 outward through the discharge communication passage 1221B; when the second cover 1222 is moved upward from the second position to the first position with respect to the first cover 1221, fluid (e.g., air) inside the air bag module 121 is introduced into the chamber 1225 through the suction communication passage 1222B. The eight elastic members 1224 abut between the first cover 1221 and the second cover 1222, biasing the second cover 1222 to move to the first position with respect to the first cover 1221.
In this embodiment, the first sealing member 1223 may be an O-ring. However, the number, structure, and type of the first seal members are not limited to the present embodiment. For example, in another embodiment, the vacuum pump may include two or more first sealing members. Alternatively, in another embodiment, the first sealing member may be omitted.
In this embodiment, preferably, for the balance of the first cover 1221 and the second cover 1222, the eight elastic members 1224 are spaced between the edge of the first cover 1221 and the edge of the second cover 1222. Also, each resilient member 1224 may be a compression spring. However, the number and configuration of the elastic members are not limited to the present embodiment. For example, in another embodiment, the vacuum pump may comprise only one resilient member within the chamber abutting between a central portion of the first cover and a central portion of the second cover.
Specifically, the first cover 1221 includes an inner wall 1221C and an outer wall 1221D located outside the inner wall 1221C. The second cover 1222 includes an inner protruding platform 1222C and an outer abutment platform 1222D located outside the inner protruding platform 1222C. The chamber 1225 is enclosed by the inner wall 1221C and inner protruding platform 1222C. Eight accommodating spaces 1221E are formed between the inner wall 1221C and the outer wall 1221D. The eight resilient members 1224 are disposed within the eight receiving spaces 1221E and abut the outer abutment platform 1222D, respectively, to bias the second cover 1222 to move to a first position relative to the first cover 1221. It should be noted that the arrangement of the resilient member disposed outside the chamber may effectively facilitate evacuation of the gas bag module, as compared to the arrangement of the resilient member disposed within the chamber, since the volume of the chamber may be reduced as much as possible.
In addition, the first cover 1221 further includes four first engagement portions 1221F protruding outward from the inner wall 1221C. The second cover 1222 also includes four second engagement portions 1222E protruding inwardly from the outer abutment platform 1222D, the four first engagement portions 1221F engaging the four second engagement portions 1222E, respectively, when the second cover 1222 is moved to the first position relative to the first cover 1221.
In this embodiment, preferably, the four first engaging portions 1221F are spaced along an edge of the first cover 1221, and the four second engaging portions 1222E are spaced along an edge of the second cover 1222. Further, each of the first engagement portions 1221F may be a hook, and each of the second engagement portions 1222E may be an L-shaped structure. However, the number and structure of the first engaging portions and the number and structure of the second engaging portions are not limited to the present embodiment. For example, in another embodiment, the first cover may include only one first engagement feature projecting inwardly from the inner wall, and the second cover may include only one second engagement feature projecting outwardly from the inwardly projecting platform.
To facilitate assembly of the vacuum pump 122 with the air bag module 121, the vacuum pump 122 further includes a connector 1226 and a second sealing member 1227. The connection head 1226 can be connected to the air bag module 121 by high-frequency heat sealing, and detachably connected to the suction port 1222A. The connecting head 1226 has a connecting communication passage 1226A, and the connecting communication passage 1226A is configured to communicate the air bag module 121 with the suction communication passage 1222B. The second sealing member 1227 is provided between the connector 1226 and the suction port 1222A for preventing fluid from leaking from a gap between the detachable connector 1226 and the suction port 1222A.
In this embodiment, the second sealing member 1227 may be an O-ring. However, the number of the second sealing members and the structure of the vacuum pump are not limited to the present embodiment. For example, in another embodiment, the vacuum pump may include two or more sealing members disposed between the detachable connector and the suction inlet. Alternatively, in another embodiment, the connection head may be fixedly connected to the suction port, and the second sealing member may be omitted, that is, the connection head and the suction port, that is, the second cover may be formed as one integral structure. Alternatively, in another embodiment, the air bag module may be directly connected to the suction port, and the connector may be omitted.
To facilitate evacuation of the air bag module 121, the vacuum pump 122 may further include an exhaust check valve 1228 and a suction check valve 1229. The discharge check valve 1228 may be disposed on the discharge port 1221A and configured to allow only the fluid within the chamber 1225 to flow out of the chamber 1225 in one direction via the discharge communication passage 1221B. The suction check valve 1229 may be disposed on the connection head 1226 and configured to allow only a unidirectional flow of fluid within the air bag module 121 into the chamber 1225. However, the arrangement of the discharge check valve and the suction check valve is not limited to this embodiment. For example, in another embodiment, the suction check valve may be disposed on the suction port.
When evacuation of the air bag assembly 121 is required to ensure proper fit of the shoe 11, the wearer can wear the shoe 11 to step on the vacuum pump 122 to force the second lid 1222 to move from the first position to the second position relative to the first lid 1221; when the second cover 1222 is moved from the first position to the second position relative to the first cover 1221, the chamber 1225 is compressed to force the fluid within the chamber 1225 outwardly through the vent communication passage 1221B, thereby evacuating the bag assembly 121, whereby the upper portion 111 of the shoe 11 may be reformed and the shoe 11 tightened to achieve a proper fit of the shoe 11; also, in the above process, the suction check valve 1229 prevents the fluid in the chamber 1225 from flowing into the gas bag module 121; further, the first sealing member 1223 prevents the fluid in the chamber 1225 from flowing out through the gap between the first cap 1221 and the second cap 1222, and the second sealing member 1227 prevents the fluid in the chamber 1225 from flowing out through the gap between the connector 1226 and the suction port 1222A.
Thereafter, when the vacuum pump 122 is released, the eight resilient members 1224 may recover to move the second cap 1222 from the second position to the first position relative to the first cap 1221; when the second cover 1222 is moved from the second position to the first position with respect to the first cover 1221, the fluid in the air bag module 121 flows into the chamber 1225 via the connection communication passage 1226A and the suction communication passage 1222B; in the above process, the discharge check valve 1228, the first sealing part 1223, and the second sealing part 1227 prevent the external fluid from flowing into the chamber 1225, thereby improving the evacuation efficiency of the air bag module 121.
However, the vacuum pump of the present invention is not limited to evacuating an air bag assembly provided on a shoe. The vacuum pump may also be used to evacuate an air bag module disposed on a garment, bag, wristband or associated wearable accessory.
Compared with the prior art, the vacuum pump arranged on the shoe bottom is utilized to evacuate the air bag assembly arranged on the upper part of the shoe. Thus, the present invention allows the wearer to reform the upper portion of the shoe for the wearer by pumping the air bag assembly with a foot pedal vacuum pump, thereby ensuring proper fit of the shoe. No other operation is needed, and the use is convenient.
It will be apparent to those skilled in the art that various modifications and variations can be made in the apparatus and method while retaining the teachings of the present invention. Accordingly, the above disclosure should be construed as limited only by the scope of the appended claims.
