Abstract

A built-in air pump comprises a housing body and a panel. The panel couples to the housing body and defines an opening. A main pump body couples to the housing body and defines a first accommodating chamber in fluid communication with the opening and with a first and a second venting port. An air replenishing pump has an air replenishing pump body that is located adjacent to the main pump body. The air replenishing pump body couples to the housing body and defines a second accommodating chamber having therein the air replenishing pump. An air passage switch, located in the first accommodating chamber, is moveable between a first and a second position. A controller is in electrical connection with the air replenishing pump and configured to activate the air replenishing pump based on a time determination. An inflatable body including the built-in air pump assembly is also disclosed herein.

First claim

What is claimed is:

1. A built-in air pump for an inflatable body, comprising,
a housing body and a panel, said panel being coupled to said housing body and defining an opening in fluid communication with an outer environment od the inflatable body;
a main pump body coupled to said housing body and defining a first accommodating chamber, a first venting port, and a second venting port, said first accommodating chamber being in fluid communication with said opening, said first venting port and said second venting port;
an air replenishing pump having an air replenishing pump body, said air replenishing pump body located adjacent to said main pump body and coupled to said housing body, said air replenishing pump body defining a second accommodating chamber having therein said air replenishing pump;
an air passage switch located in said first accommodating chamber, said air passage switch being moveable between a first position and a second position;
wherein when said air passage switch is in said first position, said air passage switch, said main pump body, and said first venting port collectively define an inflation air passage;
wherein when said air passage switch is in said second position, said air passage switch, said main pump body, and said second venting port collectively define a deflation air passage; and

a controller in electrical connection with said air replenishing pump, said controller configured to activate said air replenishing pump based on a time determination;
wherein said main pump body comprises a pump body lid plate, said pump body lid plate defining a first upper lid port and a second upper lid port;
wherein when said air passage switch is in said first position, said first upper lid port is in fluid communication with said opening and said first venting port to establish said inflation air passage; and
wherein when said air passage switch is in said second position, said second upper lid port is in fluid communication with said opening and said second venting port to establish said deflation air passage.

2. The built-in air pump according to claim 1 , further including at least one connecting member located between said main pump body, said air replenishing pump body and said housing body to connect said main pump body and said air replenishing pump body to said housing body.

3. The built-in air pump according to claim 2 , wherein said at least one connecting member comprises a pair of connecting members, one connecting member of said pair of connecting members being located between said main pump body and said housing body to connect said main pump body to said housing body, and another connecting member of said pair of connecting members being located between said air replenishing pump body and said housing body to connect said air replenishing pump body to said housing body.

4. The built-in air pump according to claim 1 , wherein said controller includes a time counter configured to begin counting time in response to a preset condition, and said controller activates said air replenishing pump in response to said time counter counting to a preset time.

5. The built-in air pump according to claim 4 , wherein said preset condition comprises a pressure inside the inflatable body being equal to a preset pressure.

6. The built-in air pump according to claim 4 , wherein said time counter is configured to reset time of said time counter to a preset start time in response to said time counter counting to said preset time.

7. The built-in air pump according to claim 1 , wherein said controller is located in said housing body.

8. The built-in air pump according claim 1 , wherein said air passage switch includes a knob, a gear, and a push plate;
wherein said knob is located on an exterior surface of said panel, said knob being adjacent to said opening of said panel;
wherein said push plate is located in said first accommodating chamber, said push plate being below and coupled to said pump body lid plate;
wherein said gear is coupled to said push plate and said knob through said opening; and
wherein said push plate is rectilinearly movable in response to a rotational movement of said knob.

9. The built-in air pump according to claim 8 , wherein said first venting port and said second venting port are located opposite of one another whereby said first venting port receives a first valve rod and said second venting port receives second valve rod.

10. The built-in air pump according to claim 8 , further including a main pump and a toggle switch, said main pump being located in said first accommodating chamber and below said push plate, said toggle switch being located on said push plate and coupled to said main pump for activating and deactivating said main pump.

11. The built-in air pump according to claim 2 , wherein said housing body includes a first connecting part, said main pump body includes a second connecting part, and said at least one connecting member is connected to said first connecting part and said second connecting part.

12. The built-in air pump according to claim 11 , wherein said first connecting part is located at an outer periphery of said opening, and said second connecting part is located at an outer periphery of said main pump body.

13. The built-in air pump according to claim 11 , wherein said at least one connecting member has a generally ring-shape and is coupled to said first connecting part and said second connecting part via a snap-fit engagement.

14. The built-in air pump according to claim 11 , further including a pair of sealing rings, one sealing ring of said pair of sealing rings being located between said at least one connecting member and said first connecting part, and the other sealing ring of said pair of sealing rings being located between said at least one connecting member at said second connecting part.

15. The built-in air pump according to claim 1 , wherein said air replenishing pump includes:
a core defining an inlet port, an outlet port, and an a core opening;
at least one pivot arm including a magnet and a cup, said magnet and said cup being coupled to said at least one pivot arm, said cup being coupled to said core and covering said core opening to define an air chamber; and
an electromagnetic device configured to generate magnetic flux causing said magnet and said at least one pivot arm to move, thereby causing said cup to compress and expand said air chamber.

16. The built-in air pump according to claim 15 , wherein, in response to said cup expanding said air chamber, said air replenishing pump draws air into said air chamber through a first one-way valve located at said inlet port; and, in response to said cup compressing said air chamber, said air replenishing pump discharges air from said air chamber through a second one-way valve located at said outlet port.

17. The built-in air pump according to claim 15 , wherein said at least one pivot arm comprises a pair of pivot arms located on opposing sides of said core and covering said core opening.
