As shown in the drawings, the water spraying apparatus having water saving function includes a pressurizing motor 1 and a first nozzle 2. Wherein, the pressurizing motor 1 is in communication with a first nozzle 2 through a water pipe (not shown).

As shown in FIG. 1, the pressurizing motor 1 is controlled by a control circuit (not labeled). The pressurizing motor 1 includes:

• a shell 11, a motor bobbin 12, a rotation disc 13, a piston restricting seat 14, and a plurality of pistons 15, and a pressuring device 16.

The motor bobbin 12 is placed in the shell 11 in a rotation way, to receive the power from the control circuit to rotate.

The rotation disc 13 is placed in the shell 11 in a rotation way. The rotation disc 13 is connected and fixed to one side of the motor bobbin 12 through a rotation rod (not labeled), so that when the motor bobbin 12 is rotated, it will bring the rotation disc 13 into rotation together. It is worth to note that, the surface of the rotation disc 13 is disposed slantwise, so that the direction of the surface of the rotation disc 13 is changed constantly during rotation. Moreover, a set of magnets 131 of the same or opposite magnetic polarity are embedded in the surface of the rotation disc 13, to rotate along together with the rotation disc 13 in rotation.

The piston restricting seat 14 is fixed to one side of the shell 11, and is provided with a plurality of channels 141 connected to and in communication with the receiving space in the shell 11.

Each of the piston 15 is placed in the respective channel 141, and one end of each piston 15 is pressed against the surface of the rotation disc 13 by means of an elastic mechanical piece (not shown). As such, when the rotation disc 13 is rotated, the respective pistons 15 make reciprocal movement asynchronously.

The elastic mechanical piece can be a spring, and it can be placed on the piston restricting seat 14 or the respective pistons 15 based on design requirement. The restoring force of the spring is used to press one end of the respective pistons 15 against the surface of the rotation disc 13. It is worth to note that, one end of the piston 15 is provided with a magnet, and depending on design requirement, the magnet of the rotation disc 13 and the magnet of the piston 15 can be made to be magnetically attractive or repulsive.

In addition, the first connection cover 22 is provided with an opening 221 for outputting water, to form a divergent structure from inside to outside, so that the mixed air and water is sprayed from the first nozzle 2 in a radiation manner.

It is worth to note that, the inner structure of the first nozzle 2 is designed to form no evident obstacle to the water and air flowing through, such that the water spray out direction is dependent on the shape of the opening 221.

Second Preferred Embodiment

In addition to the arrangement and cooperation of a pressuring motor 1 and the first nozzle 2. The first nozzle 2 can be replaced with other types of nozzles based on actual requirement.

Refer to FIGS. 3a and 3b respectively for a side exploded view of a second nozzle used in a water spraying apparatus having water saving function according to the present invention; and a top view of a connection head of a second nozzle according to the present invention. In the present embodiment, the water spraying apparatus having water saving function includes a pressuring motor 1 and a second nozzle 3, connected together through a water pipe.

The second nozzle 3 includes a second connection head 31 and a second connection cover 32, connected together by means of thread-and-lock.

Inside the second connection head 31 is provided with a plurality of water channels 311. Between the two blocking rings 312 outside is provided with a plurality of offshoot openings 313 in an encircling manner, so that the plurality of offshoot openings 313 are in communication with the plurality of water channels 311. It is worth to note that, among the blocking rings 312, for the blocking ring 312 disposed on one end of the second connection head 31, a plurality of cutouts 314 are formed around the rim of the ring. One end of plurality of cutouts 314 is extended between the blocking rings 312, while the other end is extended to the end surface of the second connection head 31, as shown in FIG. 3b. From the planar side view of one end of the second connection head 31, it can be known that, the plurality of cutouts 314 are disposed in a ring shape periodically. The function of the plurality of cutouts 314 will be described later. In addition, the other end of the second connection head 31 is provided with wave-shape slip resistance surface 315, for the water pipe to sleeve on, and it is not easy to detach due to friction force. Moreover, certain portion on the surface of the second connection head 31 is provided with threads 316 for locking and fixing, to connect the second connection cover 32.

The surface of the second connection cover 32 is penetrated and provided with a through hole 321 connected to inside of the cover. Certain portion on the inner wall of the second connect cover 32 is provided with threads 322, so that the second connection head 31 can be placed inside the second connection cover 32. As such, the second connection cover 32 and the second connection head 31 can be connected together through using threads 316 and 322 in a rotation way to avoid detachment. It is worth to note that, after the second connection head 31 is connected to the second connection cover 32, the inside of the second nozzle 3 is divided into two cavities: the first cavity (not shown), and the second cavity (not shown). The first cavity is a ring shape cavity, and is disposed between the inner wall of the second connection cover 32, and the blocking ring 312. The second cavity is disposed between one end of the second connection head 31, and the inner side top surface of the second connection cover 32. Then, through the plurality of cutouts 314, the first cavity and the second cavity are connected and in communication. Since the second connection head 31 and the second connection cover 32 are connected in a rotation way, the second cavity utilizes this rotation mechanism to adjust the distance between one end of the second connection head 31, and the inner side top surface of the second connection cover 32, so as to adjust the size of the second cavity.

However, in the process of utilizing the second nozzle 3, water and air may leak in the gap between the second connection head 31 and the second connection cover 32, due to insufficient tight connection between the second connection cover 32 and the second connection head 31. In order to avoid water and air leakage from the second nozzle 3, the second connection head 31 located below the first cavity can be sleeved an elastic ring 317. As such, through using the elastic ring 317 sandwiched between the second connection head 31, and the inner wall of the second connection cover 32, water and air can be prevented from leaking from the first cavity. Further, the elastic ring 317 can reduce further the friction between the second connection head 31 and the second connection cover 32, to prolong the service life of the second nozzle 3.

Upon receiving water and air by the second nozzle 3 from the pressuring motor 1, the water and air is filled into the first cavity through the plurality of offshoot openings 313. When the first cavity is completely filled, the water and air is guided into the second cavity through the plurality of cutouts 314. As shown in FIG. 3b, the plurality of cutouts 314 are so disposed that, when water and air enters the second cavity, it produces spiral-shape water flow in the second cavity. When the second cavity is filled with water flow, it is ejected and sprayed out from the through hole 321 in a spiral way.

Moreover, refer to FIG. 3c for a perspective view of a second nozzle after it is assembled according to the present invention. As shown in FIG. 3c, a user is allowed to adjust the second nozzle 3 in a rotation way, to adjust the size of the second cavity, in achieving adjusting water spraying angle of the second nozzle 3.

The third connection cover 42 is connected securely to one end of the third connection head 41 through threads (not shown), while the output end of the Y-shape water channels 411 is placed inside the inner cover 422. The blade 412 is rotated through the driving push of water and air. In the rotation process, air and water is guided selectively into various different branches for output based on the position of blades of the turbine 412. Therefore, the Y-shape water channels 411 output the water and air in an asynchronous manner, and then push the plurality of blades 4222, to make the inner cover 422 to rotate and sway. In operation, when the inner cover 422 accumulates sufficient air and water, the water and air will be sprayed out spirally through the hole in the inner cover 422, hereby raising the washing force of water through the driving force of spiral movement of water.

When the third nozzle 4 receives water and air coming from the pressuring motor, water and air will pass through the Y-shape water channels 411, so that the blade 412 will be pushed by water and air to rotate, and then distributed selectively to the respective branches for output based on the position of the blades 412.
