The first cavity 221 and the second cavity 222 are communicated through a through hole 223, the first cavity 221 is rotatably connected to the outer wall of the motor chamber 111, and at this time, the output shaft of the motor 21 is accommodated and connected in the first cavity 221 and extends into the second cavity 222 through the through hole 223. The transmission chain 23 is accommodated and connected in the second cavity 222, and the second cavity 222 is through-connected with two sides of the water pumping assembly 30 and the water jetting assembly 40, so that the water pumping assembly 30 and the water jetting assembly 40 can be connected with the transmission chain 23 through the through-hole.

The water jet pump 42 includes a piston cylinder 421, a piston rod 422, a positioning column 423, and a spring 424.

In this embodiment, the first check valve 51 and the second check valve 52 are both elastic silicone members, and the elastic silicone members are elastically connected to the inner walls of the water inlet 4211 and the water jetting port 4212 by springs. In other embodiments of the present invention, the first check valve 51 and/or the second check valve 52 may be provided as a check valve having a slit which is opened when a force is applied thereto, and the check valve may be fixed in the water inlet 4211 and/or the water injection port 4212.

The piston rod 422 is movably connected in the piston cylinder 421, a sealing ring 4221 is arranged at the end of the piston rod 422 in the piston cylinder 421, the side wall of the piston rod 422 outside the piston cylinder 421 is provided with a top stair tooth 4222, and the top stair tooth 4222 is in meshed connection with the gear with missing teeth of the third gear 411. The positioning column 423 is provided opposite to the open end of the piston cylinder 421. Spring 424 is connected between locating post 423 and piston rod 422. When the piston rod 422 reciprocates in the piston cylinder 421 under the control of the second transmission set 41 and the spring 424, the water column in the water tank can be extracted and ejected by cooperating with the first check valve 51 and the second check valve 52.

Specifically, when the water injection function of the driving bellows 1 needs to be activated, the switch 14 is rotated to toggle the rotating shaft 2321 to move in the sliding hole 121, so as to drive the rotating member 22 to rotate in the direction of the second transmission set 41, so that the output tooth 232 is engaged with the fourth gear 412. When the motor 21 is started, the motor 21 drives the second transmission set 41 to rotate through the transmission chain 23. During the rotation of the second transmission set 41, the gear with missing teeth of the third gear 411 meshes with the teeth 4222 and drives the piston rod 422 to move towards the positioning column 423, at this time, the spring 424 compresses to store energy, the first check valve 51 is driven to move towards the direction of opening the water inlet 4211 due to the change of air pressure in the piston tube 421, so that water in the water tank can enter the piston tube 421 through the water inlet 4211. With the continuous rotation of the second transmission set 41, the gear with missing teeth is separated from the top stair teeth 4222, and at this time, the piston rod 422 moves along with the return movement of the spring 424, and the second check valve 52 is pushed by the air pressure to move towards the direction of opening the water jet port 4212, so that the water in the piston cylinder 421 can be jetted from the water jet port 4212 under the push of the piston rod 422, and the water jet is completed. If the motor 21 is continuously rotated, the control piston rod 422 will reciprocate several times in the piston cylinder 421 through the transmission chain 23 and the second transmission set 41, so as to realize continuous water injection. Since the first check valve 51 and the second check valve 52 are elastically and movably connected to the water inlet 4211 and the water jetting port 4212, when the air pressures inside and outside the water inlet 4211 and the water jetting port 4212 are balanced, the first check valve 51 and the second check valve 52 are moved by the elastic force to close the water inlet 4211 and the water jetting port 4212.
