When the pressure rod is pressed against the water pump body, it is in the water outlet state. The water outlet pressure keeps the water inlet piston away from the water inlet valve, and the water outlet piston is away from the water outlet valve. The water inlet valve is in a closed state, and the water outlet valve is in an open state. There is no water when spraying water. Backflow.

The water pump body further includes an upper cover and a lower cover combined into a water container, and a piston at one end of the spring that can press the spring, and the water outlet valve and the water inlet valve are arranged on the lower cover. The pressing rod exerts force on the piston, thereby pushing the water in the water container out from the water outlet valve.

A water outlet joint and a water inlet joint are connected at the water outlet valve and the water inlet valve. The water outlet joint is connected with an outlet pipe and a water outlet gland sleeved on the water outlet pipe. The water outlet gland is provided with a water outlet, and the water outlet is smaller than the diameter of the water outlet pipe so that the speed of water flowing through the water outlet is accelerated. , forming a jet. The water inlet joint is connected with a water inlet pipe.

Compared with the prior art, the button of the utility model has the following beneficial effects:

The water spray mechanism of the utility model is provided with a one-way through-flow piston at the water inlet/outlet, which can realize one-way water outlet, has flexible functions, compact structure, and good water spray effect.

【Detailed ways】

As shown in Figures 1 and 2, a water spray mechanism includes a pressure rod 2 and a water pump body 3. A spring 33 is arranged in the water pump body 3, and the pressure rod 2 and the water pump body 3 can move relatively. The water pump body 3 further includes a water outlet valve 321 , a water inlet valve 322 , and a water outlet piston 11 and a water inlet piston 12 placed at the water outlet valve 321 and the water inlet valve 322 .

The water outlet piston 11 and the water inlet piston 12 are T-shaped pistons. When the water is in the water state, the water inlet pressure keeps the water inlet piston 12 away from the water inlet valve 322, and the water outlet piston 11 blocks the water outlet valve 321, and the water inlet valve 322 is open. state, the water outlet valve 321 is in a closed state. When the pressure rod 2 is pressed against the water pump body 3, it is in the water outlet state. The outlet water pressure makes the outlet piston 11 away from the outlet valve 321, and the inlet piston 12 blocks the inlet valve 322. The inlet valve 322 is in a closed state, and the outlet valve 321 is in an open state. state, there is no backflow of water when spraying water.

The water pump body 3 further includes an upper cover 31 and a lower cover 32 combined into a water container, and a piston 34 located at one end of the spring 33 that can press the spring 33 . The water outlet valve 321 and the water inlet valve 322 are arranged on the lower cover 32 . The pressing rod 2 exerts force on the piston 34 , thereby pushing the water in the water container out from the water outlet valve 321 .

A water outlet connector 13 and a water inlet connector 14 are connected to the water outlet valve 321 and the water inlet valve 322 . The water outlet joint 13 is connected with an outlet pipe 15 and a water outlet gland 17 sleeved on the outlet pipe 15, the water outlet gland 17 is provided with a water outlet 171, and the water outlet 171 is smaller than the diameter of the outlet pipe 15, so that When the water flows through the water outlet 171, the speed increases to form a jet. The water inlet joint 14 is connected with a water inlet pipe 16 .

Referring to Fig. 3-Fig. 6, when the pressure rod 2 is pressed, the pressure rod 2 pushes the piston 34 to push the spring 33 in the water pump body 3, the spring 33 stores potential energy, the volume of the water pump body 3 shrinks, and the outlet water pressure makes the water outlet The piston 11 is far away from the water outlet valve 321, and the water inlet piston 12 blocks the water inlet valve 322. The water inlet valve 322 is in a closed state, and the water outlet valve 321 is in an open state. The water in the water pump body 3 passes through the water outlet valve 321, the water outlet joint 13, and the water outlet pipe 15, spray out by the water outlet 171 of water outlet gland 17 again.

When the spring 33 is pressed to the shortest by the pressure rod 2, the potential energy of the spring 33 is the largest, the internal volume of the water pump body 3 is the smallest, the water storage is the smallest, and the water spray is in the end state.

When the pressure rod 2 is released, the spring 33 releases the potential energy, pushes the pressure rod 2 and the piston 34 to reset, and the internal volume of the water pump body 3 increases, so that the water pressure at the water inlet valve 322 pushes the water inlet piston 12 away from the water inlet valve 322, and the pressure difference pushes the piston 12 away from the water inlet valve 322. The water outlet piston 11 blocks the water outlet valve 321, the water inlet valve 322 is in an open state, the water outlet valve 321 is in a closed state, and water enters the water pump body 3 through the water inlet pipe 16 and the water inlet valve 322.

When the potential energy of the spring 33 is fully released, the pressure rod 2 and the piston 34 are fully reset, the inner volume of the water pump body 3 is the largest, the water storage is the largest, and the water intake is in the end state.

In this way, the water spraying and water intake functions of the water spraying mechanism are realized, and there is no phenomenon of water backflow during water spraying.
