Description

Technical Field

[0001] The utility model relates to the field of nozzles, in particular to a lifting type water film nozzle. Background Art

[0002] During the construction and maintenance of some green lawns, the grass needs to be watered and maintained. In order to facilitate the watering of lawns and green spaces, municipal management departments will build smart irrigation systems. The water outlet of such irrigation systems is often equipped with a lifting water film nozzle. When the irrigation system is supplied with water, this type of water film nozzle pushes the water core tube out through water pressure, and the water flow is sprayed under the guidance of the pattern nozzle.

[0003] However, in the actual watering process, due to the characteristics of the geographical features, the green lawn is not a flat road structure. The frequency of watering required for the lawn area at a low position is much less than that at a high position. The existing lifting water film sprinkler head does not have a closed control structure for the water spray core tube. As a result, during the irrigation operation, water is discharged simultaneously at high and low positions of the lawn, thereby wasting the entire water resource. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-5 A lifting water film nozzle shown in the figure includes a connecting sleeve 1, a water spray core tube 3 is inserted and connected in the middle of the connecting sleeve 1, a pipe cap 2 for sealing is arranged on the top of the connecting sleeve 1, a blocking ring 101 is sleeved on the top of the connecting sleeve 1, the pipe cap 2 and the top of the connecting sleeve 1 are threadedly sleeved, an external thread is arranged on the top of the connecting sleeve 1, and an internal thread is opened on the inner wall of the pipe cap 2. Through the threaded cooperation between the two, the pipe cap 2 can be threadedly sleeved on the outer wall of the connecting sleeve 1, and at the same time, the setting of the blocking ring 101 limits the sleeve depth of the pipe cap 2.

[0025] Specifically, a spray hole is formed on the outer wall of the top of the water spray core tube 3 , a pattern nozzle 302 is arranged in the spray hole, and an adjusting button 301 for adjusting the setting angle of the pattern nozzle 302 is arranged at the top of the water spray core tube 3 .

[0026] It should be noted that the main body of the entire water film nozzle of this scheme refers to the sprinkler nozzle model PT-06, which is often used in the field of irrigation for underground use. After the water flows through this type of nozzle, the internal water spray core tube 3 is pushed upward under the impact of water pressure, and the pattern nozzle 302 is exposed. At this time, the water flows through the pattern nozzle 302 and is sprayed out. According to the style setting of the pattern nozzle 302, the water flow sprayed through the nozzle of this scheme forms a water film, so it is called a water film nozzle.

[0027] The top of the pipe cap 2 is provided with a blocking mechanism for blocking the water spray core pipe 3, and the blocking mechanism includes:

[0028] The blocking rod 4 is slidably inserted and connected to the top of the pipe cap 2;

[0029] The plugging plate 7 has one end sleeved with a rotating member, and the rotating member is arranged at the top end of the pipe cap 2. The plugging plate 7 controls the plugging opening and closing of the water spray core tube 3 by rotating and adjusting.

[0030] Specifically, an arc-shaped slot 201 is provided at the top of the pipe cap 2 , and the bottom of the blocking rod 4 is slidably inserted into the arc-shaped slot 201 . A bayonet 701 is provided at one end of the sealing plate 7 away from the rotating part, and the top of the blocking rod 4 is sleeved in the bayonet 701 .

[0031] In the setting of this scheme, the opening shape of the arc-shaped slide groove 201 is a "⊥" line, and a limiting slider is set at the bottom of the blocking rod 4. The limiting slider is disc-shaped, and the radius is the same as the opening width at the bottom of the arc-shaped slide groove 201. In this way, the blocking rod 4 can always maintain a straight state and slide along the arc-shaped slide groove 201.

[0032] Furthermore, the rotating member comprises:

[0033] Place the sleeve 5 and fix the sleeve 5 on the top of the pipe cap 2;

[0034] The rotating rod 6 has its bottom rotatably inserted into the placement sleeve 5, a torsion spring 8 is arranged on the outer wall of the rotating rod 6 and located in the placement sleeve 5, and the top of the rotating rod 6 is sleeved with one end of the sealing plate 7.

[0035] Furthermore, a blocking ring 601 is sleeved on the bottom of the rotating rod 6, and the blocking ring 601 is rotatably inserted and connected to the inner wall where the top of the sleeve 5 is placed.

[0036] It should be noted that when the water spray core tube 3 needs to be in an open state, the blocking plate 7 needs to be rotated so that the end of the blocking plate 7 away from the rotating rod 6 leaves from directly above the water spray core tube 3. During the rotation of the blocking plate 7, the rotating rod 6 will be driven to rotate synchronously. At this time, the rotating rod 6 causes the torsion spring 8 to rotate and twist in the rotating state, thereby accumulating elastic potential energy. When the blocking plate 7 rotates more than ninety degrees in the counterclockwise direction, the baffle rod 4 is moved close to the blocking plate 7, and the bayonet 701 is aligned with the top of the baffle rod 4 for clamping, thereby blocking the blocking plate 7 from rotating back to the top of the water spray core tube 3, so that the water spray core tube 3 can be pushed out to spray water under water pressure.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
