An inflatable entertainment device is characterized by comprising an inflatable toy and an expansion connecting piece, wherein the inflatable toy is used for entertainment, the inflatable toy comprises a first inflatable toy, the inflatable toy is provided with at least one inflatable toy opening, and the expansion connecting piece is connected to the inflatable toy opening; the expansion connecting piece is provided with an expansion connecting port which can allow airflow to pass through, and at least one expansion connecting piece on the first inflatable toy can be connected with at least one expansion connecting piece on a second inflatable toy so as to connect the second inflatable toy to the first inflatable toy in an expansion mode, so that the inflation entertainment equipment is expanded; the inflatable toy also comprises an inflation/suction pipeline, wherein at least part of the pipeline of the inflation/suction pipeline is connected with the first inflatable toy and can be communicated with at least one air source so as to inflate or pump the first inflatable toy; and at least part of the pipeline of the air inflation/extraction pipeline is connected with the expansion connecting port, so that when the second air inflation toy is connected in an expansion way, the air inflation/extraction pipeline can be further connected with the second air inflation toy in an expansion way, and the first air inflation toy and the second air inflation toy in the expansion way in the air inflation entertainment equipment can respectively do independent and time-sharing staggered actions when air inflation/extraction is carried out.

2. The inflatable entertainment device of claim 1, wherein said air supply provides at least one set of air outlet and air inlet openings simultaneously to the exterior; the air outlet and the air suction port are communicated with the expansion connecting port through the air filling/pumping pipeline.

3. An inflatable entertainment apparatus according to claim 1 or 2, wherein said inflation/deflation line branches at least partially into at least two primary branches.

4. An inflatable entertainment device according to claim 3, characterized in that at least one of said primary branches into at least two secondary branches.

5. An inflatable amusement device according to claim 1 wherein at least one of said first inflatable toy and/or at least one of said second inflatable toy is provided with a plurality of said inflatable toy openings and, correspondingly, a plurality of said expansion joints for simultaneous connection to a plurality of said inflatable toys and/or said inflation/deflation line.

6. The inflatable entertainment device of claim 1, wherein at least some of said inflatable toy openings and said expansion connectors associated therewith are bi-directional inflation/deflation interfaces that allow both inflation and deflation, such that at least some of said inflatable toys are capable of being inflated and deflated, such that at least some of said inflatable toys in said inflatable entertainment device are capable of receiving independent simultaneous inflation/deflation or non-simultaneous inflation/deflation, and inflation and deflation can be switched at any time.

7. An inflatable entertainment apparatus according to claim 1, wherein said first inflatable toy and/or said second inflatable toy is a receiving inflatable toy having a receiving space for providing an entertainment space and/or carrying all or part of the rest of said inflatable toy.

8. The inflatable entertainment device of claim 2, further comprising an inflation and deflation regulating device disposed on at least one of: the air source, the air filling/extracting pipeline and the inflatable toy are arranged on the air source;

the inflation and exhaust regulating device is provided with at least one air valve to realize the change of the inflation, exhaust and air-closing states of the inflatable toy, thereby realizing that at least part of the inflatable toys are independent and do not inflate/exhaust or close air at the same time, and can be respectively switched at any time.

9. The inflatable entertainment device of claim 8, wherein the air valve of the inflation and deflation regulating means comprises at least two shut-off valves in communication with the air outlet port and the air intake port, respectively; alternatively, the first and second electrodes may be,

the air valve on the air charging and exhausting regulation and control device comprises a three-position three-way valve which is simultaneously communicated with the air outlet, the air suction port and the expansion connecting port; alternatively, the first and second electrodes may be,

the air valve on the air charging and exhausting regulation and control device comprises a two-position four-way valve which is simultaneously communicated with the air outlet, the air suction port and the expansion connecting port.

10. An inflatable amusement device according to claim 8 wherein at least part of said inflation/deflation line is independently provided with said inflation and deflation control means and/or at least part of said inflatable toy is independently provided with said inflation and deflation control means.

11. The inflatable entertainment device of claim 1, wherein said expansion link further comprises a locking portion, said locking portion being capable of interlocking with a locking portion of another of said expansion links; the expansion connecting ports at the butt joint end of the expansion connecting piece are circumferentially provided with butt joint sealing parts, and the butt joint sealing parts can seal the outside and ventilate the inside after the two expansion connecting ports are in butt joint; the expansion connecting port at the back end of the expansion connecting piece is provided with an air pipe connecting part, and the air filling/pumping pipeline can be connected to the air pipe connecting part so as to be communicated with the expansion connecting port.
