When the ball is blown up from the air blowing port, the probability of collision between the balls before and after being blown up becomes high, which causes the ball to spread out from the main air flow on the line connecting the air blowing port and the ball outlet in all directions. Since the ball swirls so as to drop toward the air blowing upper opening side again, the balls in the ball stirring housing can be uniformly stirred.

Further, according to the present invention, since the balls accommodated in the ball agitating and accommodating portion are made of a relatively small-diameter and lightweight foam such as urethane foam, the balls are blown up even if the air volume of the blower is small. This makes it possible to reduce the size of the entire device.

Further, in claim 3, since the air vent gap is provided at the boundary between the upper and lower hemispherical bodies forming the ball agitating and accommodating portion, the ball agitator is blown by blowing air from the air vent gap to the outside. A part of the main air flow in the storage part is sucked out to generate a turbulent flow, and this turbulent flow sucks the ball blown up by the main air flow from the air blowing port to the outside of the main air flow. It is possible to promote the diffusion of the ball.

Furthermore, in claim 4, since a plurality of protrusions are provided on one side near the inner bottom of the air blowing port formed in the lower hemispherical body forming the ball agitating and accommodating portion, the inner surface of the lower hemispherical body is formed. A part of the balls that are concentrated and fall along the air blowing upper opening can be temporarily restrained in the vicinity of the air blowing upper opening, and it is possible to prevent the intensive ball falling into the air blowing upper opening. Therefore, the ball does not block the air blow-up port, and the ball can be smoothly blown up.

Further, in claim 5, since the power supply device for driving the blower is incorporated in the base, it is convenient to carry.

Further, in the present invention, the blower is composed of a vertical sirocco fan, and since the discharge port is directly connected to the air outlet formed on the upper surface of the base, the blower can be downsized. It is possible to reduce the size of the entire device.

Further, in the present invention, since the face plate-shaped sound insulating member is provided at a portion corresponding to the outside of the air suction port formed on the side surface of the blower with a predetermined air suction allowable interval. In addition, it is possible to minimize the leakage of wind noise and fricative noise of the suctioned air due to the rotation of the fins generated in the blower to the outside, thereby enhancing the sound deadening effect.
