Description

Technical Field

[0001] The utility model relates to the technical field of gardening, in particular to a gardening irrigation device. Background Art

[0002] In the daily maintenance of landscaping, watering is particularly important. Water is a solvent for many substances. Minerals, oxygen, carbon dioxide, etc. in the soil must first be dissolved in water before they can be absorbed by plants and circulate in the body. Therefore, in order to ensure the survival rate of green seedlings, frequent irrigation is required to ensure sufficient water. Watering is roughly divided into three periods, namely spring water, growth water and winter water. In the past, mobile tankers or pre-buried irrigation pipes were used for landscaping maintenance. Mobile tankers stored water and moved for irrigation. Maintenance staff needed to drive tankers regularly to carry out targeted irrigation in the maintenance area. The workload was large and the equipment cost was also high. The pre-buried irrigation pipe can achieve one-button irrigation, which is simple and convenient, but the sprinkler head on the irrigation pipe is in an exposed state for a long time, the sprinkler head is corroded and rusted, and is prone to malfunction, and often no water is discharged or water is discharged from a single hole.

[0014] 1. The overall structure of the utility model is simple and compact. It adopts a non-powered design principle and makes full use of the high-pressure water provided during irrigation water supply. Under the impact of the high-pressure water and the buoyancy, the base of the nozzle assembly is driven to move upward. When the base moves to the highest limit, the magnetic sheets are attracted to each other. Under the action of the attraction force and the buoyancy, the nozzle assembly is fixed in the sleeve. At this time, the nozzle rises to the highest point and starts spraying. After the irrigation is completed, the high-pressure water falls, and the nozzle assembly is under the action of its gravity. At this time, the gravity of the nozzle assembly is greater than the attraction force, and the nozzle assembly descends along the sleeve to return to its original position, and the nozzle enters the through hole.

[0023] The following is combined with Figure 1-4 , the technical solution of the utility model is further explained:

[0024] like Figure 1-Figure 3 As shown, a landscaping irrigation device includes a vertical pole 1, a sleeve 6 is provided inside the vertical pole 1, and a water supply port connected to a pre-buried pipe is provided at the bottom of the sleeve 6. A nozzle assembly is movably provided in the sleeve 6, and the top of the nozzle assembly passes through the upper portion of the sleeve 6 and out from the top of the vertical pole 1. In other words, the vertical pole is embedded with a sleeve, and the nozzle assembly is provided within the sleeve and the vertical pole, and the end of the nozzle assembly passes out from the top of the vertical pole to spray and irrigate the external area. During use, water from the buried pipe network enters the sleeve through the water supply port and then enters the nozzle assembly to spray the external area.

[0025] In some embodiments, as Figure 4 As shown, the nozzle assembly includes a connecting rod 8, a base 5, and a nozzle 3. The nozzle 3 is connected to the base 5 via the connecting rod 8. The base 5 is provided with a water inlet that communicates with the interior of the connecting rod 8 and the interior of the sleeve 6. The nozzle 3 extends outward through the through hole 10 at the top of the vertical pole 1. In other words, the nozzle is located at the top of the vertical pole, the connecting rod and the base are located inside the sleeve, and the interior of the connecting rod is also a cavity structure.

[0026] It should be noted that the diameter of the through hole 10 is slightly larger than the diameter of the nozzle 3 in the nozzle assembly to facilitate the upward and downward movement of the nozzle 3 within the through hole, and the height of the through hole is greater than the height of the guide groove to prevent water droplets from flowing into the through hole. In other words, the through hole diameter is larger than the nozzle diameter, and the through hole has a U-shaped structure. However, it should be noted that in the initial state of the nozzle, the nozzle is inside the through hole, and the outer wall of the nozzle slightly contacts the inner wall of the through hole.

[0027] Specifically, if Figure 1-3 As shown, a limit member 4 is provided on the inner wall of the sleeve 6. That is, under the action of high-pressure water, the nozzle assembly moves upward along the inner wall of the sleeve 6 and engages with the limit member 4 embedded in the inner wall of the sleeve 6, thereby temporarily securing the nozzle assembly within the sleeve. In other words, as high-pressure water enters the sleeve, the nozzle assembly is pushed upward as the high-pressure water gradually increases. When the nozzle assembly reaches the upper limit, the nozzle assembly connects and secures with the limit member, thereby temporarily securing the nozzle assembly within the sleeve.

[0028] Specifically, the base 5 is circular, and the upper portion of the sleeve 6 defines a guide channel for accommodating the circular base. This channel allows the circular base to move upward under the buoyancy of high-pressure water. A first magnetic plate is mounted on the circular base, which engages with a retaining member. In other words, under the force of high-pressure water, the circular base rises along the guide channel until it connects and secures with the retaining member, securing the nozzle assembly within the sleeve.

[0029] In some embodiments, a limiting step is formed between the guide channel and the inner wall of the lower half of the sleeve 6. The limiting step cooperates with the limiting member 4 to limit the vertical movement range of the circular base within the sleeve. In other words, the height adjustment range of the nozzle assembly is limited by the position of the limiting step and the limiting member, and the limiting step and the limiting member can prevent the nozzle assembly from moving too far vertically.

[0030] In some embodiments, as Figure 1-3 As shown, the position-limiting member 4 includes a second magnetic sheet that attracts the first magnetic sheet, thereby temporarily securing the base 5 within the sleeve 6 under the action of high-pressure water and the combined effects of the first and second magnetic sheets. In other words, the impact of the high-pressure water and the buoyancy of the sheet drive the base of the nozzle assembly upward. When the base reaches the highest limit, the magnetic sheets attract each other, and the nozzle assembly is secured within the sleeve under the combined effects of attraction and buoyancy. The nozzle then rises to its highest point and begins spraying.

[0031] When the high-pressure water supply stops, the nozzle assembly moves downward along the inner wall of the sleeve 6 under the action of gravity and disengages from the stopper 4. In other words, when irrigation stops, the high-pressure water falls, and the nozzle assembly, under the action of its gravity, which is greater than the suction force, descends along the sleeve to return to its original position, and the nozzle enters the through hole.

[0032] Specifically, if Figure 1 and Figure 4 As shown, a deflector 2 is provided at the top of the vertical pole 1. A through hole 10 is provided at the top of the vertical pole 1 for the nozzle assembly to pass through. A guide groove 9 is provided on the periphery of the through hole 10, communicating with the interior of the vertical pole 1. A filter is embedded in the guide groove 9, so that water droplets flowing along the deflector are filtered by the filter before flowing into the interior of the vertical pole. In other words, water droplets or rainwater that drip onto the deflector flow along the curved deflector into the guide groove, filtered by the filter, and then flow into the guide groove. Then, it flows into the interior of the vertical pole through the guide groove, thereby completing the water collection function of the vertical pole and achieving a certain effect of saving water resources.

[0033] In some embodiments, the upright pole 1 has a hollow structure, a one-way water valve 7 is provided at the bottom of the upright pole 1, and the bottom of the upright pole 1 is connected to the sleeve 6, so that water droplets in the upright pole 1 can flow through the one-way water valve 7 and be stored in the sleeve 6. In other words, a guide groove is integrated in the upper part of the upright pole, the upright pole adopts a hollow structure, and the bottom of the upright pole is connected to the sleeve, so that the upright pole as a whole forms a water collection system, so that water droplets dripping onto the deflector are collected in the sleeve through the upright pole, achieving a water-saving effect.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
