Abstract

An inflatable product that includes a chamber and an electric air pump for inflating the chamber. The air pump has an air intake and an air outlet. The air intake is connected to the outside of the chamber and the air outlet is connected to the inside of the chamber when the air pump is moved to a first position. The air intake is connected to the inside of the chamber and the air outlet is connected to the outside of the chamber when the air pump is moved to a second position.

Claims

1. An inflatable product, including:

a first chamber;

a first manually-controlled valve;

an air pump for inflating the first chamber through the first manually-controlled valve;

a first switch for activating the air pump and opening the first manually-controlled valve; and

a switch circuit through which the air pump is activated by the first switch, wherein the switch circuit has a second switch turned on by the first switch when the first switch is turned on, and a relay activated to supply the air pump with power when the second switch is turned on.

2. The inflatable product as claimed in claim 1, wherein the second switch is a microswitch.

3. The inflatable product as claimed in claim 1, further comprising:

a second chamber;

a second manually-controlled valve through which the air pump inflates the second chamber; and

a third switch to activate the air pump and open the second manually-controlled valve, wherein the switch circuit has a fourth switch turned on by the third switch when the third switch is turned on, and the relay is activated to supply the air pump with power when the fourth switch is turned on.

4. The inflatable product as claimed in claim 3, wherein the fourth switch is a microswitch.

5. An inflatable product, including:

a first chamber;

a first pack body;

a first valve disposed in the first pack body;

an air pump for inflating the first chamber through the first valve;

a first switch, disposed on the first pack body, for activating the air pump and opening the first valve; and

a switch circuit through which the air pump is activated by the first switch, wherein the switch circuit has a second switch turned on by the first switch when the first switch is turned on.

6. The inflatable product as claimed in claim 5, wherein the second switch is a microswitch.

7. The inflatable product as claimed in claim 5, wherein the second switch is disposed in the first pack body.

8. The inflatable product as claimed in claim 5, wherein the switch circuit has a relay activated to supply the air pump with power when the second switch is turned on.

9. The inflatable product as claimed in claim 5, further comprising:

a second chamber;

a second valve, disposed in the first pack body, through which the air pump inflates the second chamber; and

a third switch, disposed on the first pack body, to activate the air pump and open the second valve, wherein the switch circuit has a fourth switch turned on by the third switch when the third switch is turned on.

10. The inflatable product as claimed in claim 9, wherein the fourth switch is a microswitch.

11. The inflatable product as claimed in claim 9, wherein the fourth switch is disposed in the first pack body.

12. The inflatable product as claimed in claim 9, wherein the switch circuit has a relay activated to supply the air pump with power when the fourth switch is turned on.

13. The inflatable product as claimed in claim 5, further comprising:

a second chamber;

a second pack body;

a second valve, disposed in the second pack body, through which the air pump inflates the second chamber; and

a third switch, disposed on the second pack body, to activate the air pump and open the second valve, wherein the switch circuit has a fourth switch turned on by the third switch when the third switch is turned on.

14. The inflatable product as claimed in claim 13, wherein the fourth switch is a microswitch.

15. The inflatable product as claimed in claim 13, wherein the fourth switch is disposed in the second pack body.

16. The inflatable product as claimed in claim 13, wherein the switch circuit has a relay activated to supply the air pump with power when the fourth switch is turned on.
