Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water dispersion device suitable for various uses such as water dispersion for watering, etc., fluid pumps, hose connectors, etc.

The water dispersion means is usually a water spraying device that has a shielding flange attached coaxially to the water spout hole and a bowl-shaped diffusion curved surface around the flange, but this device can only diffuse and discharge high-pressure water (in a straight line). It cannot be used as a means of pumping other liquids, as a hose-to-hose connector, or for low-pressure water discharging such that water can be poured into containers without scattering.

Moreover, such a device has a complicated and expensive structure for switching between diffusion and water spraying.

The present invention provides a water diffusion device that can perform diffusion, high-pressure water spray, low-pressure water spray, and fluid transport (pump) with one device, has extremely simple switching operations, and is simple in structure and inexpensive.

Embodiments of the present invention will be explained below with reference to the drawings. In FIG.
The nozzle 1 has a normal tapered shape 3, and a negative pressure forming pipe 6 is connected continuously to the outer surface of the nozzle 1 with a diameter comparable to the large diameter 4 of the nozzle 1.

This negative pressure forming tube 6 has an air introduction hole 7 formed in the tube wall at a position corresponding to the nozzle tip, and a bent tube 8 is detachably connected to the tip of the negative pressure forming tube 6.

This bent pipe 8 consists of a connecting cylinder part 9 and a water sprinkler pipe part 10, and the intersection angle α between the axial extension line 11 of the connecting cylinder part 9 and the axis 12 of the water sprinkler pipe part 10 is about 45 degrees, The length L of the water pipe portion 10 is configured to be approximately 1.7 times the diameter of the bent portion.

When dispersing the injected water using the above device of the present invention, if the water is injected from the nozzle with the air introduction hole open (first
(See Figure 2), since the injection port is open to the atmosphere, the nozzle travels straight through the negative pressure forming pipe with its diameter unchanged and collides with the inner wall of the water sprinkling pipe of the bent pipe. A flow parallel to the axis along the axis and a spiral flow along the inner surface are released from the water pipe, and when released, the centrifugal force of the spiral flow causes the water to spread radially, making it suitable for water spraying.

If the length of the water sprinkling pipe section is more than twice the diameter of the bent section, the diffusion of the ejected water will be extremely narrowed.

This is thought to be due to the stalling of the flow velocity due to the collision and the merging of the spiral flow and the straight flow within the sprinkler pipe section.

Next, when diffusion is not the purpose, the air introduction hole is closed with a fingertip as shown in FIG. 3, and the injection is performed.

In this case, since the area around the injection port of the nozzle is under negative pressure, the jet flow spreads within the negative pressure forming pipe and fills the pipe, and water is discharged from the water sprinkling pipe portion of the bent pipe at a low speed.

Therefore, the water spray is hardly spread out and is suitable for water injection, etc.

Furthermore, when used as high-pressure water spray, the bent pipe is released from the negative pressure forming pipe and the water is directly injected from the nozzle tip.

In addition, when collecting and transporting various floating substances and transport water,
The introduction hole is immersed in the liquid and a jet stream is injected from the nozzle.

In this case, since the diameter of the negative pressure forming tube is smaller than the diameter of the tip of the nozzle, the introduction hole becomes a negative pressure due to the jet stream, and the liquid is sucked in and sent out along with the jet stream, thereby performing a pumping action.

As described above, with the simple configuration of providing a bent tube of a predetermined size at the tip of the negative pressure forming tube with the air introduction hole and the nozzle exiting, the injection water can be diffused extremely efficiently.
By simply opening and closing the air inlet hole, you can selectively use the injection water diffusion or stall water discharge, and since there is no constriction in the negative pressure forming tube, by removing the bent tube, you can use it as high-pressure water discharge or use the air inlet tube in the flowed material. It can be used for various purposes such as being used as a flow pump if immersed in water.
