Advantageously, the spring force of the third spring 24 is smaller than the spring force of the second spring 33.

The use method of the invention comprises the following steps:

in the initial state, the water collecting spring 17, the intake spring 30, the relief spring 33, and the pressurizing spring 24 are all in the stretched state.

In rainy days, the water collecting groove 43 can collect rainwater, and the rainwater flows into the water tank 15 after the water collecting spring 17 is stretched by pressing the fourth valve core 18.

When a user rides the bicycle, the pedal is stepped to drive the bicycle crank 11 to rotate, the bicycle crank 11 rotates and simultaneously drives the gear 12 to rotate, the gear 12 drives the driven wheel 25 to rotate through tooth meshing, the driven wheel 25 after rotating reciprocates the piston rod 51 through the connecting rod 26, when the piston rod 51 is pulled towards the bottom, the air in the air inlet cavity 42 is extruded, the pressure in the air inlet cavity 42 is increased, a part of air pushes the first valve core 31 to enable the air inlet spring to stretch and then enter the air storage cavity 40, when the piston rod 51 is pushed towards the top, the pressure in the air inlet cavity 42 is reduced, the external air enters the air inlet cavity 42 from the air hole 28, and meanwhile, due to the resetting of the air inlet spring 30, the air in the air storage cavity 40 cannot flow back to the air inlet cavity 42.

After the piston rod 51 is continuously moved, meanwhile, the air in the air storage cavity 40 is also continuously compressed, when the air is compressed to a certain degree, the air cannot be continuously compressed, firstly, the air in the air storage cavity 40 can push the third valve core 23 to enable the pressurizing spring 24 to stretch and then enter the water tank 15, when water exists in the water tank 15, the air entering the water tank 15 can extrude the water into the first water pipe 48, when the temperature is insufficient, the piston switch 57 can plug the water distribution pipe 21, so that the water cannot continuously advance, because the water cannot be discharged, the pressure in the water storage cavity 15 is increased to a certain degree, the air in the air storage cavity 40 is continuously compressed, at the moment, part of the further compressed air can push the second valve core 34 to enable the pressure relief spring 33 to stretch and then be discharged to the outside, and the residual compressed air is stored in the air storage cavity 40.

When the bicycle saddle is exposed to the sun in summer, the liquid 56 in the sealed box 19 is boiled due to high temperature, the volume of the boiled liquid 56 expands to push the sliding piston 20 outwards, the sliding piston 20 pushes the piston switch 57 to move, the first water pipe 48 is communicated with the water dividing pipe 21, the pressure in the water tank 15 is higher than the external atmospheric pressure, so that the water in the water tank 15 is extruded to the first water pipe 48 by the gas in the water tank 15, the water originally blocked by the piston switch 57 is extruded to the water dividing pipe 21, the water dividing pipe 21 divides part of the water to the second water pipe 37, the other part of the water to the third water pipe 22, the water flowing to the second water pipe 37 can cool the sealed box 19, and the water flowing to the third water pipe 22 can be sprayed to cool the bicycle saddle 35.

When a person rides, the weight of the person blocks the third water pipe 22 by the pressing block 36, and the pressurized water can only flow out of the second water pipe 20 to cool the seal box 19 and not cool the saddle 35.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
