Wherein: 1. the air duct comprises a fan, 2 parts of an air duct, 3 parts of a baffle, 4 parts of vent holes, 5 parts of force unloading holes, 6 parts of ball inlets, 7 parts of limiting snap rings and 8 parts of bulges.

Detailed Description

The invention will now be further described by way of non-limiting examples with reference to the accompanying drawings:

specific example 1: the utility model provides a ball device is inhaled to negative pressure for ocean ball equipment, includes fan 1, air pipe 2 and baffle 3, fan 1 locates air pipe 2's import department, one side that is linked together with fan 1's air outlet in air pipe 2 is located to baffle 3 be equipped with ventilation hole 4 on the baffle, be equipped with goal mouth 6 on air pipe 2 for inhale air pipe 2 with ocean ball from goal mouth 6 by oneself, the back one side of baffle 3 is located to goal mouth 6.

The baffle 3 is a half-moon-shaped baffle, and the bending direction of the inner arc and the bending direction of the outer arc of the baffle 3 are consistent. Baffle 3 is fixed on air pipe 2's inner wall, is equipped with spacing snap ring 7 in air pipe 2's relevant position department for guarantee that baffle 3 can not remove in air pipe 2.

The size of the ventilation hole 4 on the diameter of the circular transparent pipe ranges from 1/5 to 1/2 of the diameter of the circular transparent pipe.

The round transparent pipeline is provided with the force unloading hole 5, so that a plurality of ocean balls can move in the round transparent pipeline at the same time, and outside air enters the ventilation pipeline 2 through the force unloading hole 5, so that new ocean balls can be sucked into the ventilation pipeline 2 after the ocean balls in front pass through the force unloading hole 5.

Specific example 2: the ventilating pipeline 2 is a circular transparent pipeline, and the inner wall of the circular transparent pipeline is provided with a bulge 8 for preventing the ocean ball from rotating in the circular transparent pipeline. The rest of the structure is the same as in embodiment 1.

Specific example 3: unload power hole 5 and locate air pipe 2's air outlet department, can make the ocean ball can move farther distance like this, make simultaneously in the air pipe 2 can have a plurality of ocean balls to move. The aperture of the force-releasing hole 5 is smaller than the outer diameter of the ocean ball, and the rest structure is the same as that of the specific embodiment 2.

Specific example 4: the ball inlet is arranged on one side of the ventilation pipeline 2, the ventilation pipeline 2 is connected with another section of ventilation pipeline 2 in an inserted mode through a connector, so that ocean balls far away from the baffle can be sucked into the ventilation pipeline 2, and the rest of the structure is the same as that of the specific embodiment 3.

The working principle is as follows: in the circular transparent pipe of wind entering that the air outlet of fan blew off, when the baffle, wind can only pass through in the ventilation hole on the baffle, because the area of ventilation hole is less than the area of baffle, so the passageway becomes narrow when wind moves baffle department, just so makes the pressure reduction at the baffle back form the negative pressure to make the ocean ball follow ocean ball goal enter into in the circular transparent pipe and with leave the wind of baffle department and remove from circular transparent pipe together.

The above embodiments have explained the present invention in detail.
