Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
An air box device for infant entertainment comprises an outer box body 1, wherein a left air inlet is formed in a left side plate of the outer box body 1, a right air inlet is formed in a right side plate of the outer box body 1, a left baffle 2 and a right baffle 3 for stopping the left air inlet and the right air inlet are respectively hinged to the inner wall of the outer box body 1, a push-pull piston plate 12 is arranged between the left baffle 2 and the right baffle 3, the inner space of the outer box body 1 is divided into a left cavity 4 and a right cavity 5 through the push-pull piston plate 12, and a push-pull rod 7 connected with the push-pull piston plate 12 is arranged outside the outer box body 1.
When the push-pull rod 7 is pushed to enable the push-pull piston plate 12 to be far away from the right side plate and close to the left side plate, air in the left chamber 4 is compressed, and the left baffle plate 2 on the left side plate automatically blocks the left air inlet under the action of air pressure; meanwhile, the air pressure in the right chamber 5 becomes low, when the air pressure in the right chamber 5 is lower than the atmospheric pressure outside the outer box body 1, the right baffle 3 is directly jacked up by the external atmospheric pressure, the right chamber 5 is communicated with the external atmosphere, and the external atmosphere supplements the air for the right chamber 5. When the push-pull rod 7 is pulled, the actions of the components are just opposite, the left chamber 4 is supplemented with air, and the right chamber 5 is compressed with air.
The front side plate of the outer box body 1 is a transparent plastic plate, and the motion state of the push-pull rod 7 driving the push-pull piston plate 12 can be clearly seen through the front side plate. A transparent ventilation pipeline 6 is arranged in the outer box body 1, the left end opening of the ventilation pipeline 6 faces to the left side plate of the outer box body 1, the right end opening of the ventilation pipeline 6 faces to the right side plate of the outer box body 1, and the push-pull piston plate 12 is drawn in a reciprocating mode within the length range of the ventilation pipeline 6. The inside of the ventilation pipeline 6 is hinged with a switching plate 8, and the front side of the ventilation pipeline 6 is provided with an air outlet 9 corresponding to the free end of the switching plate 8. When the air in the right chamber 5 is compressed, the switching plate 8 is pressed towards the left chamber 4 by the high-pressure air in the right chamber 5, the right chamber 5 is communicated with the air outlet 9, the left chamber 4 is isolated from the air outlet 9, and the left chamber 4 is in a state of air supplement. When the air in the left chamber 4 is compressed, the process is reversed. The switching plate 8 can be seen through the transparent ventilation duct 6 in a circularly oscillating motion state.
The air outlet 9 is connected with a transparent exhaust pipe 10, a hollow thin plastic ball 11 is placed in the exhaust pipe 10, and the hollow thin plastic ball 11 can be blown up by air exhausted from the air outlet 9, so that the movement principle and the blowing-up phenomenon of the air box are demonstrated.
Further, the distance between the left port of the ventilation pipeline 6 and the left side plate of the outer box 1 is equal to the distance between the right port and the right arm of the outer box 1, so that the stability of air flow can be ensured when the right chamber 5 exhausts air to the air outlet 9 and the left chamber 4 exhausts air to the air outlet 9. The switching plate 8 is arranged at the midpoint of the length direction of the ventilation pipeline 6, and the stability of air supply from the two cavities to the air outlet 9 can be ensured.
Further, the exhaust pipe 10 comprises a semicircular pipe 10-1 attached to the front side plate of the outer box 1, the lower end opening of the semicircular pipe 10-1 is communicated with the air outlet hole 9, the upper end opening of the semicircular pipe 10-1 is connected with an annular pipe 10-2, the hollow thin plastic ball 11 is placed in the annular pipe 10-2, and the top end of the annular pipe 10-2 is provided with an air outlet 10-3. The hollow thin plastic ball 11 can move up and down in the annular tube 10-2 with the change of the speed of the push-pull rod, thereby not only having an educational function, but also having fun.
Further, the left side plate, the right side plate, the rear side plate and the upper side plate of the outer box body 1 are made of transparent plastic plates, and the structural characteristics and the motion process inside the outer box body 1 can be observed conveniently from all sides.
Furthermore, a vertical round tube 10-4 is arranged between the semicircular tube 10-1 and the annular tube 10-2, height scale marks 10-5 are arranged on the round tube 10-4, and the round tube 10-4 can enable the hollow thin plastic ball 11 to move in a diversified manner, so that the ornamental value and the interestingness are increased.
The present invention is not exhaustive and is well known to those skilled in the art.
