when the reference point moves to the farthest end from the motor 1, that is, the end of the crank 222 that is closest to the pump body 231, the corresponding plunger 232 enters the stroke distance L1+ L2, that is, the distance from the plunger 232 to the center of the output shaft of the motor 1.

When the reference point moves to the nearest end from the motor 1, i.e., the end of the crank 222 that is farthest from the pump body 231, the corresponding plunger 232 enters the stroke distance L2-L1, i.e., the distance from the plunger 232 to the center of the output shaft of the motor 1.

When the reference point moves to a position between the nearest end of the motor 1 and the farthest end of the motor 1, and the horizontal included angle between the connecting line between the reference point and the circle center of the eccentric wheel 221 is theta, the horizontal distance corresponding to the eccentric distance L1 is L1 COS theta, the vertical distance corresponding to the eccentric distance L1 is L1sin theta, and the horizontal distance corresponding to the stroke distance L2 is thetaAt this time, the corresponding plunger 232 enters the stroke distance to satisfy:

according to actual requirements, appropriate values are set, and the control mechanism 3 is matched with corresponding parameters to control the specific stroke of the plunger 232.

In an embodiment of the present invention, the water spray demand data includes: water spray water pressure demand data, water spray quantity demand data and/or water spray angle demand data.

In this embodiment, the water spray water pressure demand data, the water spray water amount demand data and/or the water spray angle are input to the interactive component 41, and are transmitted to the control mechanism 3 through the interactive component 41, the control mechanism 3 calculates the motor operation angle data θ according to the water spray water pressure demand data, the water spray water amount demand data and/or the water spray angle, and controls the motor 1 to do circular arc positive and negative alternate motion according to the motor operation angle data θ, thereby driving the plunger 232 to move, so as to spray the water amount required by the target through the pump body 231, the water pressure required by the target and the spray angle required by the target, thereby realizing the electronization of each function of the water pump 23, and improving the efficiency of the loom.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
