Abstract

A suction device and a connector are provided. The suction device has a control electromagnetic core and a suction member. A cavity is provided between the control electromagnetic core and the suction member. The suction member is operative to slide up and down within the cavity in response to changes of a magnetic property of the control electromagnetic core.

First claim

What is claimed is:

1. A suction device, wherein the suction device comprises:
a control electromagnetic core; and
a suction member;
wherein a cavity is provided between the control electromagnetic core and the suction member, and the suction member slides up and down within the cavity according to changes of a magnetic property of the control electromagnetic core to realize gas introduction and gas exhaust.

2. The suction device according to claim 1 , wherein the control electromagnetic core is connected with a control circuit which controls a magnetic pole of the control electromagnetic core according to a current flowing direction of the control circuit itself.

3. The suction device according to claim 1 , wherein the suction member comprises:
a cap;
a sliding pillar; and
a sucker;
wherein the cap is located at an end of the sliding pillar, an exhaust slim hole is provided within the sliding pillar, an exhaust cavity exists between an end of the exhaust slim hole and the cap, and another end of the exhaust slim hole is connected with a guiding hole in a center of the sucker.

4. The suction device according to claim 3 , wherein the sliding pillar slides up and down upon receipt of pulling up and down by the cap so as to change a size of the exhaust cavity.

5. The suction device according to claim 3 , wherein an exhaust hole is provided at a lateral surface of the sliding pillar, and the exhaust hole communicates with the exhaust cavity when the cap pulls up the sliding pillar.

6. The suction device according to claim 3 , wherein the suction member further comprises an elastic appendage, an end of which is connected with a top of a groove which is outside the sliding pillar and is disposed along a circumferential direction.

7. A connector, comprising:
a body having a plurality of the suction devices embedded on the body;
wherein each of the suction devices comprises:
a control electromagnetic core; and
a suction member;
wherein a cavity is provided between the control electromagnetic core and the suction member, and the suction member slides up and down within the cavity according to changes of a magnetic property of the control electromagnetic core to realize gas introduction and gas exhaust.

8. The connector according to claim 7 , wherein the control electromagnetic core is connected with a control circuit which controls a magnetic pole of the control electromagnetic core according to a current flowing direction of the control circuit itself.

9. The connector according to claim 7 , wherein the suction member comprises:
a cap;
a sliding pillar; and
a sucker;
wherein the cap is located at an end of the sliding pillar, an exhaust slim hole is provided within the sliding pillar, an exhaust cavity exists between an end of the exhaust slim hole and the cap, and another end of the exhaust slim hole is connected with a guiding hole in a center of the sucker.

10. The connector according to claim 9 , wherein the sliding pillar slides up and down upon receipt of pulling up and down by the cap so as to change a size of the exhaust cavity.

11. The connector according to claim 9 , wherein an exhaust hole is provided at a lateral surface of the sliding pillar, and the exhaust hole communicates with the exhaust cavity when the cap pulls up the sliding pillar.

12. The connector according to claim 9 , wherein the suction member further comprises an elastic appendage, an end of which is connected with a top of a groove which is outside the sliding pillar and is disposed along a circumferential direction.
