Go up the inside of cavity 4 and be fixed with water film pipe 3 through hollow grid 7, there is the clearance of predetermineeing the distance between water film pipe 3 and the middle space grid 7, the top of water film pipe 3 sets up to the arc opening, first cavity 101 is stretched into to the bottom of water film pipe 3, water film pipe 3 is inside to be fixed with center post 5 through two water film grids 6 of laying from top to bottom, the top of center post 5 is provided with the water film baffle 1 that corresponds with arc opening shape, the bottom of center post 5 embolias inside the top of moving core 10, be provided with the compression spring 9 of cover in the center post 5 outside between water film grid 6 of below and first arch 1041.

The working principle is as follows:

the movable core 10 forms reverse backwater in the movable core 10 by water columns from bottom to top in the water inlet pipe 12, and slides up and down by the thrust of water.

The moving core 10 is provided with a restoring force in the opposite direction by the compression spring 9 at its upper end, and when balanced with the pushing force, the moving core 10 is held in a fixed position.

As shown in fig. 4, when the pushing force provided by the water is small, the water column pushes up the movable core 10, the top end of the first cavity 101 contacts with the third protrusion 81, and the water flow enters the water film pipe 3 only from the water passage 1011 and passes through the water film grid 6 and the water film baffle 1 to form a water film state.

When the water thrust is correspondingly increased, as shown in fig. 5, the top end of the first cavity 101 is separated from the third protrusion 81, and the water flow enters the water film tube 3 from the water passage 1011, and can form an upward direct flow through the gap between the water film tube 3 and the upper cavity 4, at this time, the water film and the hollow direct flow are in a mixed state, the water inlet thrust is continuously changed, and the water column is in a changing state of unfolding and folding the flower, i.e. a changeable composite state.

When the water thrust is large enough, the first baffle 103 of the movable core 10 contacts with the lower end of the water film tube 3, the path of the water flow entering the water film tube 3 from the water passage 1011 is blocked, and only the path of the gap between the water film tube 3 and the upper cavity 4 is reserved, and the hollow direct-current water state is completely presented at this time, as shown in fig. 6.

In one example, the central column 5 is fixed within the water film tube 3 by two water film grates 6 in an interference fit.

In one example, the water film baffle plate 1 is provided with an internal threaded hole, the top end of the central column 5 is provided with an external thread, and the water film baffle plate 1 can be adjusted in position up and down along the central column 5 through the threads and is fixed through a fastener. Further, the fastener is a fastening nut 2, and the form of the fastener is not further required in the present application.

In one example, the bottom end of the upper cavity 4 and the top end of the lower cavity 8 are connected by a screw thread, and the pushing force of the compression spring 9 is finely adjusted by the relative rotation between the upper cavity 4 and the lower cavity 8.

In one example, the central column 5 is a hollow member, an internal thread is added in the hollow member, a screw 13 in threaded connection is arranged in the hollow member, the top end and the bottom end of the screw 13 both penetrate through the central column 5, a second protrusion 131 is arranged at the bottom end of the screw 13, the second protrusion 131 is arranged between the water film grid 6 and the compression spring 9 below, and the distance can be adjusted downwards or upwards by abutting against the compression spring 9 through the screw 13, so that the thrust of the compression spring 9 can be finely adjusted, as shown in fig. 7.

The above embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above embodiments are only specific embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
