The air at both ends of the channel flows from bottom to top, and the air flow rate increases. Since the greater the fluid speed, the smaller the fluid pressure, the external air pressure is higher than the air pressure at the end of the channel, which helps the convection of the external air and the air in the channel, and effectively improves the air circulation between the external air and the air in the channel. As the inner airbag rotates continuously, the inner airbag moves up and down in the outer airbag, and the air in the external air, the working chamber and the channel circulate with each other. This structure relies on the gravity of the human body to achieve automatic ventilation of the air in the channel when the human body moves, actively drives the flow of air in the channel, thereby greatly improving the air circulation in the water walker, greatly improving the heat dissipation of the water walker, and also helps to evaporate the accumulated water in the channel, thereby improving the comfort of the human body in the channel.

DETAILED DESCRIPTION

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] Reference Figures 1 to 4 , a water walker, comprising:

[0026] The outer airbag 1 comprises a cylindrical portion 11 and annular portions 12 respectively located at both ends of the cylindrical portion 11, wherein the middle of the annular portion 12 comprises an inlet 13, wherein a first air nozzle 14 is disposed on one of the annular portions 12;

[0027] The cylindrical inner airbag 2 is movably arranged in the cylindrical portion 11 and the two ends of the inner airbag 2 are respectively matched with the inner side surfaces of the two annular portions 12 in a clearance manner. The inner airbag 2 has a channel 27 in the axial direction, and the channel 27 is connected to the inlet 13; the first cylinder 15 and the second cylinder 25 are respectively fixed on the inner wall of the cylindrical portion 11 and the outer wall of the inner airbag 2, and a working chamber 23 is formed between the first cylinder 15 and the second cylinder 25; the edges of the two ends of the inner airbag 2 have a plurality of notches 24, and the notches 24 connect the working chamber 23 and the channel 27; the inner airbag 2 is provided with a second air nozzle 26;

[0028] Two groups of exhaust components are arranged axially along the second cylinder 25, and each group of the exhaust components includes a plurality of air cylinders 5 uniformly arranged along the circumference of the second cylinder 25, the air cylinder 5 has a cylinder body and a piston end, the cylinder body of the air cylinder 5 is fixedly arranged on the outer wall of the second cylinder 25, the piston end of the air cylinder 5 is a piston rod 51, and the piston rod 51 is slidably arranged in the axial direction of the air cylinder 5, the outer end of the piston rod 51 extends out of the air cylinder 5 and the end is hinged on the first cylinder 15, the inner end of the piston rod 51 extends into the air cylinder 5 and the end is fixedly connected with a piston 52; each of the air cylinders 5 is connected with an intake pipe 53 and an exhaust pipe 54; the outer end of the intake pipe 53 is connected to the working chamber 23, and the inner end is connected to the inside of the air cylinder 5; the outer end of the exhaust pipe 54 is connected to an annular air pipe 21, and the inner end is connected to the inside of the air cylinder 5; the intake pipe 53 and the exhaust pipe 54 are respectively provided with an intake check valve 531 and an exhaust check valve 541.

[0029] The outer airbag 1 and the inner airbag 2 are inflated and exhausted respectively through the first air nozzle 14 and the second air nozzle 26. When the water walker is in use, the outer airbag 1 floats on the water surface by buoyancy, and the human body enters the channel 27 through the entrance 13. The human body moves in the channel 27 and drives the inner airbag 2 to rotate, and the inner airbag 2 drives the outer airbag 1 to rotate through the second cylinder 25, the air cylinder 5 and the first cylinder 15, so that the water walker moves on the water surface.

[0030] During this process, the inner airbag 2 moves downward under the action of human body gravity and approaches the lower side of the outer airbag 1, that is, the space above the working chamber 23 increases, and the space below the working chamber 23 decreases. At this time, the piston rod 51 of the air cylinder 5 above the working chamber 23 extends out, and the air in the working chamber 23 enters the air cylinder 5 through the intake check valve 531 and the intake pipe 53 in sequence under the drive of the piston 52 of the air cylinder 5, and the outside air enters the upper working chamber 23 through the gap 24, and the suction process is completed at the same time; the piston rod 51 of the air cylinder 5 below the working chamber 23 retracts into the air cylinder 5, and drives the piston 52 to discharge the air in the air cylinder 5 into the passage 27 through the exhaust check valve 541 and the exhaust pipe 54 in sequence, and the air below the working chamber 23 is discharged into the passage 27 through the gap 24, and the exhaust process is completed at the same time. The air at both ends of the channel 27 flows from the bottom to the top, and the air flow rate increases. Since the greater the fluid speed, the smaller the fluid pressure, the outside air pressure is higher than the air pressure at the end of the channel 27, which helps the convection of the outside air and the air in the channel 27, and effectively improves the air flow between the outside air and the air in the channel 27. As the inner airbag 2 rotates continuously, the inner airbag 2 moves up and down continuously in the outer airbag 1, and the outside air, the working chamber 23 and the air in the channel 27 circulate with each other.

[0031] The first cylinder 15 and the second cylinder 25 support the air cylinder 5 , thereby improving the anti-deformation capability of the cylindrical portion 11 and the inner airbag 2 , and helping to improve the stability of the inner airbag 2 when moving in the cylindrical portion 11 .

[0032] This structure relies on the body's gravity to achieve automatic ventilation of the air in the channel 27 when the human body is moving, actively driving the flow of air in the channel 27, thereby effectively improving the air circulation in the water walker, greatly improving the heat dissipation of the water walker, and also helping to evaporate the accumulated water in the channel 27, thereby improving the comfort of the human body in the channel 27.

[0033] Specifically, a plurality of annular air tubes 21 are axially arranged on the inner wall of the inner airbag 2 , each of the annular air tubes 21 is connected to the outer end of an exhaust pipe 54 , and each of the annular air tubes 21 is provided with a plurality of air tube nozzles 22 .

[0034] The air in the air cylinder 5 is discharged into the channel 27 through the exhaust check valve 541, the exhaust pipe 54, the annular air pipe 21 and the air pipe nozzle 22 in sequence, further improving the flowability of the air in the channel 27.

[0035] Specifically, six notches 24 are respectively provided on the edges of both ends of the inner airbag 2 , each of the notches 24 is connected to the working chamber 23 and the channel 27 , and each of the exhaust pipes 54 passes through a notch 24 and is connected to an annular air pipe 21 .

[0036] The provision of the notch 24 facilitates the circulation of air between the working chamber 23 and the outside air, and also facilitates the connection of the air inlet pipe 53 with the annular air pipe 21 and the air cylinder 5 .

[0037] Specifically, a plurality of pull ring groups are arranged on the inner wall of the inner airbag 2 along the axial direction, and each pull ring group includes a plurality of pull rings 28 arranged along the circumferential direction of the inner airbag 2 .

[0038] The human body uses the hands and feet together through the pull ring 28, so that the pull ring 28 assists the human body in the movement of the inner air bag 2, which helps to save manpower and enables the human body to move in the water walker for a longer time.

[0039] Specifically, the piston end of the gas cylinder 1 is a piston rod 51 , and a compression spring 55 is sleeved on the piston rod 51 ; one end of the compression spring 55 presses against the first cylinder 15 , and the other end presses against the gas cylinder 5 .

[0040] The piston rod 51 located below the inner airbag 2 is retracted into the air cylinder 5 under the pressure of the second cylinder 2, and the compression spring 55 is compressed. As the inner airbag 2 rotates, the air cylinder 5 and the piston rod 51 extend out of the air cylinder 5 under the combined action of the compression spring 55 and the first cylinder 1. The setting of the compression spring 55 helps the inner airbag 2 to reset in the cylinder 11. In addition, since the outer airbag 1 floats on the water surface, the waves impact the outer airbag 1, causing the first cylinder 15 to compress the compression spring 55. Therefore, the compression spring 55 can also absorb wave energy and improve the stability of the water walking device.

[0041] Specifically, two arc-shaped fixing frames 6 are coaxially fixed on the second cylinder 25 along the axial direction through a fixing rod 66, and at least one rotating shaft 61 is rotatably provided on the two arc-shaped fixing frames 6. The axis of the rotating shaft 61 is parallel to the axis of the second cylinder 25, and a gear 62 is coaxially fixed on the rotating shaft 61. A driving mechanism that can drive the gear 62 to rotate is provided between the first cylinder 15 and the rotating shaft 61. A generator 65 is also fixed on the arc-shaped fixing frame 6, and the output shaft of the generator 65 is transmission-connected to the rotating shaft 61. A battery 3 is provided on the second cylinder 25, and the battery 3 is electrically connected to the generator 65.

[0042] Under the action of human body gravity, the inner airbag 2 and the outer airbag 1 move up and down relative to each other. At this time, the driving mechanism drives the rotating shaft 61 to rotate through the gear 62, and the rotating shaft 61 drives the generator 65 to generate electricity through gear transmission. The electric energy generated by the generator 65 is stored in the battery 3.

[0043] Specifically, a fan 4 is also provided on the inner airbag 2 , and the fan 4 is electrically connected to the battery 3 .

[0044] The fan 4 is turned on to discharge outside air into the channel 27 , thereby further improving the air flowability in the channel 27 and also helping to accelerate the evaporation of the accumulated water in the channel 27 .

[0045] Specifically, the driving mechanism includes a limit frame 63 and a rack 64. The limit frame 63 is fixed on an arc-shaped fixed frame 6, and the rack 64 is slidably set on the limit frame 63. One end of the rack 64 is fixed on the first cylinder 15, and the other end of the rack 64 is a free end. The length direction of the rack 64 is consistent with the radial direction of the first cylinder 15, and the rack 64 is meshed and connected with the gear 62.

[0046] When the inner airbag 2 and the outer airbag 1 move up and down relative to each other, the rack 64 slides up and down on the limiting frame 63, and at the same time, the rack 64 drives the rotating shaft 61 to rotate through the gear 62, so that the generator 65 generates electricity.

[0047] Specifically, a plurality of light-transmitting holes 251 are formed on the first cylinder 15 and the second cylinder 25 .

[0048] The setting of the light-transmitting hole 251 helps external light to penetrate into the channel 27, so that the water walker has a certain brightness, but at the same time the first cylinder 15 and the second cylinder 25 block excessive sunlight, making the air in the channel 27 cool, further improving the comfort of the human body in the channel 27.

[0049] Specifically, a plurality of paddling blades 7 are provided on the outer wall of the cylindrical portion 11 .

[0050] When the cylindrical portion 11 rotates, the arrangement of the paddling blades 7 helps the water walker to move on the water surface.

[0051] Specifically, a plurality of LED lamps 8 are disposed on each of the annular portions 12 , and the LED lamps 8 are electrically connected to the battery 3 .

[0052] At night, the LED lamp 8 provides illumination, which helps the water walker to be used at night.

[0053] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
