After the water encounters the suddenly narrowed end face of the throttling water inlet hole, the flow rate entering the water outlet chamber is greatly reduced, the flow rate increases instantly, and negative pressure is generated. The air outside the water outlet chamber is sucked into the inside of the water outlet chamber through the air inlet hole. The air increases the pressure of the water flow in the water outlet chamber, and instantly increases the flow rate of the water flow, so that the water flows out of the water outlet chamber at a very high flow rate. Therefore, compared with the nozzle in the prior art, the nozzle can make the water flow from the water outlet chamber at a reduced flow rate and a larger flow rate, thereby achieving a water-saving effect.

DETAILED DESCRIPTION

[0026] Specifically, the electric telescopic rod 44 is started, and the electric telescopic rod 44 drives the moving block 42 to move up and down. The moving block 42 is limited and moved up and down inside the sliding groove 41 through the sliding block 43, so that the water spraying assembly 5 connected to the moving block 42 can be driven to move up and down according to the height of the green belt, so as to facilitate the spraying and watering of the green belt.

[0027] Example 2

[0028] like Figure 1-4 As shown, on the basis of embodiment 1, the utility model provides a technical solution: preferably, the water spray assembly 5 includes a transmission pipe 50, a nozzle 51 is installed on the surface of the transmission pipe 50, and the inner cavity of the nozzle 51 is provided with a water inlet chamber 510 and a water outlet chamber 511 from the inside to the outside, the water inlet chamber 510 is connected with the water outlet chamber 511 through a throttling water inlet hole 515, and the side wall of the water outlet chamber 511 near the throttling water inlet hole 515 is provided with an air inlet hole 513, and the water outlet chamber 511 includes a first cylindrical tube 516, a first cylindrical tube 517, a second cylindrical tube 518, a second cylindrical tube 519, a second cylindrical tube 520, a second cylindrical tube 521, a second cylindrical tube 522, a second cylindrical tube 523, a second cylindrical tube 524, a second cylindrical tube 525, a second cylindrical tube 526, a second cylindrical tube 527, a second cylindrical tube 528, a second cylindrical tube 529, a second cylindrical tube 530, a second cylindrical tube 531, a second cylindrical tube 532, a second cylindrical tube 533, a second cylindrical tube 534, a second cylindrical tube 535, a second cylindrical tube 536, a second cylindrical tube 537, a second cylindrical tube 538, a second cylindrical tube 539, a second cylindrical tube 531, a second cylindrical tube 530, a second cylindrical tube 531, a second cylindrical tube 532, a second cylindrical tube 534, a second cylindrical tube 535, a second cylindrical tube 536, a second cylindrical tube 537, a second cylindrical tube 538, a second cylindrical tube 539, a second cylindrical tube 531, a second cylindrical tube 531, a second cylindrical tube 532, The second cylindrical barrel 518 is connected to the outer end of the second cylindrical barrel 518 with a nozzle 512. The inner cavity of the nozzle 512 can be optionally provided with a nozzle core 519. A protective ring 514 is also provided on the radial outer side of the air inlet 513. The protective ring 514 is sleeved on the outside of the first cylindrical barrel 516. The nozzle core 519 is a shower type nozzle or a bubble type nozzle. The side wall 517 of the connection between the first cylindrical barrel 516 and the second cylindrical barrel 518 is a downwardly inclined step surface. The inner diameter range of the throttling water inlet hole 515 is 1mm to 2mm.

[0029] Specifically, during use, water flows into the water inlet chamber 510 at a normal flow rate, and then flows into the water outlet chamber 511 through the throttling water inlet hole 515. After the water encounters the suddenly narrowed end face of the throttling water inlet hole 515, the flow rate entering the water outlet chamber 511 is greatly reduced, the flow rate increases instantly, and negative pressure is generated, and the air outside the water outlet chamber 511 is sucked into the inside of the water outlet chamber 511 through the air inlet hole 513. These air increases the pressure of the water flow in the water outlet chamber 511, and instantly increases the flow rate of the water flow, so that the water flows out of the water outlet chamber 511 at a very high flow rate. Therefore, compared with the nozzles in the prior art, the nozzle 51 can make the water flow from the water outlet chamber 511 at a reduced flow rate and a larger flow rate, thereby achieving a water-saving effect. In addition, when the water outlet end of the water outlet chamber 511 is blocked, the water pressure in the water outlet chamber 511 will continue to increase. When the water pressure increases to a certain extent, the water will flow out from the air inlet hole 513. 513 flows outward, thereby playing the role of pressure relief and alarm, so as not to affect the use. The inner cavity of the nozzle 512 can be optionally provided with a nozzle core 519. By replacing different types of nozzle cores 519, the nozzle 51 can spray water flows in different forms, so that the application range of the nozzle 51 is very wide. The nozzle core 519 can be a shower type nozzle that can spray shower type water flow; in addition, the nozzle core 519 can also be a bubble type nozzle that can spray water flow with more bubbles. When the water outlet cavity 511 is blocked and the water flow is depressurized outward through the air inlet 513, the outflowing water flow is blocked and guided by the protective ring 514, and will not be sprayed radially, but will flow outward in the protective ring 514 along the axial direction, and then flow downward along the first cylindrical tube 516 and the second cylindrical tube 518, so that the water flow can still flow out according to the normal water flow direction of the nozzle 51, avoiding the splashing of water flow after the water outlet cavity 511 is blocked.

[0030] The working principle of the watering device used in green belts will be described in detail below.

[0031] like Figure 1-4As shown, the electric telescopic rod 44 is started, and the electric telescopic rod 44 drives the moving block 42 to move up and down. The moving block 42 is limited and moved up and down in the sliding groove 41 through the sliding block 43, so that the water spraying assembly 5 connected to the moving block 42 can be driven to move up and down according to the height of the green belt, so as to facilitate the spraying and watering of the green belt. During use, water flows into the water inlet cavity 510 at a normal flow rate, and then flows into the water outlet cavity 511 through the throttling water inlet hole 515. The water flow suddenly flows into the throttling water inlet hole 515 when it encounters the throttling water inlet hole 515. After the end face becomes narrow, the flow rate entering the water outlet chamber 511 is greatly reduced and the flow rate increases instantly, generating negative pressure, and sucking the air outside the water outlet chamber 511 into the inside of the water outlet chamber 511 through the air inlet hole 513. The air increases the pressure of the water flow in the water outlet chamber 511 and instantly increases the flow rate of the water flow, so that the water flows out of the water outlet chamber 511 at a very high flow rate. Therefore, compared with the nozzles in the prior art, the nozzle 51 can make the water flow from the water outlet chamber 511 at a reduced flow rate and a larger flow rate, thereby achieving a water-saving effect.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
