    DETAILED DESCRIPTION
    [0021 ] Hereinafter, with reference to the drawings of the embodiments of the present invention, the technical solutions of the embodiments of the present invention are described clearly and completely. Obviously, the embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, other embodiments derived by a person of ordinary skill in the art without making creative efforts, all fall within the protection scope of the present invention.
    [()022] Embodiment 1 [0023] As shown in Figure 1 - Figure 3, the embodiment provides an omnidirectional switchless hydrant, which includes base 1 and outlet pipe 2. Base 1 is a tubular cavity. The inner walls of the upper portion and the lower portion of base 1 are respectively provided with snap ring 1-1 and limiting ring 1-2. Ball 4 is provided inside base 1, and ball 4 can move inside the cavity of base 1 and seal snap ring 1-1 and limiting ring 1-2. Outlet pipe 2 includes inlet end 2-2 and outlet end 2-3. Inlet end 2-2 is provided with an overflow section. The outer wall of outlet pipe 2 is provided with holding ring 2-1. During the irrigation, the overflow section passes through snap ring 1-1 and is inserted into base 1. Holding ring 2-1 is snapped on the end portion of the outlet end of base 1. The diameter of the ball is less than the diameter of the base cavity, such that the ball does not affect the water flow. The ball floats or sinks to seal the snap ring or the limiting ring and thereby plays the role of a switch. The omnidirectional switchless hydrant of the embodiment has a simple structure. During the irrigation, the user only needs to insert the outlet pipe into base 1 without turning on or off any switch, and the operation is easy.
    [0024] Further, the overflow section is a plurality of snap pillars 2-4 which are provided along the outer wall of the inlet longitudinally.
    [0025] Further, sealing groove 1-3 is provided in snap ring 1-1. A sealing ring is provided in sealing groove 1-3 to prevent leaking from the joint of the hydrant during supplying water.
    [0026] Further, outlet pipe 2 is an elbow pipe which is bent. Outlet pipe 2 can turn 360° inside base 1. When the irrigation is performed on a different field in a different direction, outlet pipe 2 only needs to be turned around, and thereby the flexibility is good. In the embodiment, the bending angle of outlet pipe 2 is 90°.
    [0027] Further, the present invention also includes cover 3 which is used to seal the outlet end of base 1 when there is no irrigation. When there is no irrigation, the cover 3 is covered on the outlet end of base 1, so as to prevent external silt from entering the pipeline. Cover 3 can be attached to base 1 by a rope or can be connected to base 1 in other common manners.
    [0028] Method of Use: [0029] When there is no irrigation, outlet pipe 2 is removed. Under the pressure of water, ball 4 pushes against snap ring 1-1 so as to seal the water path at the center of snap ring 1-1, such that the water in base 1 cannot flow out. Meanwhile, cover 3 is closed so as to prevent external silt from entering the pipeline. When the water pressure is low or the water supply is insufficient, the liquid level is lower than snap ring 1-1 of base 1, such that the water flow cannot overflow, and ball 4 sinks with the liquid level. When the water level goes down to limiting ring 1-2, ball 4 stops moving due to the action of limiting ring 1-2, such that the water path of limiting ring 1-2 is sealed.
    [0030] During the irrigation, inlet end 2-2 of outlet pipe 2 is inserted into snap ring 1-1 of base 1. Outlet pipe 2 is fixed on base 1 under the action of holding ring 2-1. Ball 4 moves downward in the cavity of base 1 under the action of the overflow section. The water flow enters outlet pipe 2 from the sidewall of the overflow section. When the field to be irrigated changes, it is unnecessary to remove outlet pipe 2. Rather, outlet pipe 2 can be directly turned to the direction of the field to be irrigated.
    [0031] Embodiment 2 [0032] As shown in Figure 4, the embodiment provides an omnidirectional switchless hydrant. In the embodiment, the overflow section is a limiting tube which is integrally formed with outlet pipe 2. The wall of the limiting tube is provided with a plurality of inlet holes 2-5. During the irrigation, ball 4 moves downward in the cavity of base 1 under the action of the overflow section, and the water flow enters outlet pipe 2 from inlet holes 2-5 in the sidewall of the overflow section.
    [0033] Since the remaining structures of the omnidirectional switchless hydrant of this embodiment are the same as those of Embodiment 1, detailed descriptions are omitted here.
    [0034] The above embodiments are merely preferred embodiments of the present invention and are not used to limit the present invention. Within the spirit and principle of the present invention, any alternations, equivalent replacements, and improvements all fall within the scope of the present invention.
