Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1 - 10 , the present invention provides an axial piston pump, including a pump body 1, a rotating assembly 2 is arranged in the pump body 1, a plurality of reciprocating plunger structures 3 are evenly distributed around the center of the rotating assembly 2, a water inlet passage 30 communicating with the corresponding reciprocating plunger structure 3 on one side of the pump body 1, and a water discharge passage 4 communicating with the corresponding reciprocating plunger structure 3 on the other side. An articulated limiting member 5 is arranged at the inner end of the reciprocating plunger structure 3, a universal articulated ring 6 is arranged at the inner end of the rotating assembly 2, a reciprocating linkage assembly 7 is arranged between the universal articulated ring 6 and the plurality of articulated limiting members 5, a swash plate structure 8 is arranged in the pump body 1, and the reciprocating linkage assembly 7 and the swash plate structure 8 cooperate to control the reciprocating plunger structure 3 at different circumferential angle positions to expand and contract. An azimuth control assembly 9 for controlling the azimuth angle of the swash plate structure 8 is arranged on the pump body 1, and an inclination angle control assembly 10 for controlling the inclination angle of the swash plate structure 8 is arranged between the azimuth control assembly 9 and the swash plate structure 8.

[0019] The external power source drives the input rotating shaft 201 to rotate, and the input rotating shaft 201 is connected to the rotor structure 202, thereby driving the rotor structure 202 to rotate in the pump body 1. This is the starting point of the power for the entire pump operation, providing the basic power for subsequent water absorption and drainage actions.

[0020] Plunger reciprocating motion: A plurality of reciprocating plunger structures 3 are evenly distributed around the central axis of the rotor structure 202. The axial plunger body 302 is installed in the axial plunger hole 301, and it cooperates with the swash plate structure 8 through the articulated limiting member 5, the universal articulated ring 6 and the reciprocating linkage assembly 7. When the rotor structure 202 rotates, the limiting member 702 rotates along the surface of the swash plate structure 8. Due to the inclination angle of the swash plate structure 8, the axial plunger body 302 is forced to perform reciprocating linear motion in the axial plunger hole 301.

[0021] Water absorption and drainage operation: When the axial plunger body 302 moves inward, a negative pressure is formed in the axial plunger hole 301, and at this time, water is sucked in through the water inlet channel 30; when the axial plunger body 302 moves outward, pressure is applied to the water in the hole, and the water is discharged through the drainage channel 4, completing a cycle of water absorption and drainage.

[0022] With the help of the inclination control component 10, the inclination angle of the swash plate structure 8 can be changed. Rotate the annular knob 1082, and by the cooperation of the external thread 1083 and the internal thread 1084, the eccentric movable shaft 104 axially moves in the eccentric shaft hole 103, and drives the swash plate structure 8 to change the inclination degree through the control link 107. When the inclination angle increases, the stroke of the axial plunger body 302 increases, the amount of water sucked in and discharged each time increases, and the water flow rate increases; when the inclination angle decreases, the stroke of the axial plunger body 302 decreases, and the water flow rate decreases accordingly.

[0023] Principle of changing the water flow direction: The orientation control component 9 is used to adjust the orientation angle of the swash plate structure 8. Rotate the adjusting worm 9032, and the adjusting worm 9032 meshes with the worm wheel 9033 on the end face of the orientation adjusting circular plate 902 to drive the orientation adjusting circular plate 902 to rotate, thereby changing the orientation of the swash plate structure 8. After the orientation of the swash plate changes, the sliding direction of the limiting member 702 on the swash plate surface changes, resulting in a change in the movement direction of the axial plunger body 302, thereby realizing the change of the water flow direction.
