Description

Technical field

[0001] The utility model belongs to the technical field of sprinkler heads, and in particular relates to a rotary sprinkler head with a buffer structure. [Background Technology]

[0002] The existing utility model patent with publication number CN201342386Y discloses a rotary sprinkler with an improved structure. During use, high-pressure water enters the sprinkler assembly from the water inlet joint and is sprayed out from the sprinkler assembly. At the moment when the high-pressure water flows in the sprinkler assembly, the water flow will generate a huge thrust on the sprinkler rotating core, causing a rigid collision between the sprinkler on the sprinkler rotating core and the sprinkler seat, which can easily cause damage to the sprinkler and the sprinkler seat, which greatly reduces the service life of the rotary sprinkler. [Utility Model Content]

[0003] The utility model aims to provide a rotary spray head with a buffer structure which can avoid rigid collision between a spray head assembly and a nozzle seat assembly, reduce collision damage and increase service life.

[0004] The utility model is realized by the following technical solutions:

[0007] A water inlet joint is provided in the water inlet of the housing, and is provided with a joint channel and a joint water outlet hole communicating with the joint channel and the water inlet of the housing;

[0008] a nozzle seat assembly, which is disposed in the housing cavity and communicated with the water outlet of the housing;

[0009] A nozzle assembly is disposed in the shell cavity and communicates with the shell cavity, and one end of the nozzle assembly is movably connected to the nozzle holder assembly;

[0010] The elastic buffer element is arranged between the shell and the nozzle seat assembly.

[0011] As described above, the rotary sprinkler head with a buffer structure, the nozzle holder assembly includes:

[0012] A nozzle seat bushing is provided with a bushing through hole communicating with the water outlet of the housing, and a nozzle seat mounting groove communicating with the bushing through hole, wherein the elastic buffer element is provided between the housing and the nozzle seat bushing;

[0013] The nozzle seat is arranged in the nozzle seat installation groove, and one end is movably connected to the nozzle assembly, and the other end is connected to the bushing through hole.

[0014] As described above, in a rotary nozzle with a buffer structure, the nozzle seat bushing is provided with an elastic member installation groove on the peripheral side of the bushing through hole, one end of the elastic buffer element is installed in the elastic member installation groove, and the other end is against the shell.

[0015] In the rotary sprinkler with a buffer structure as described above, a first sealing ring is provided between the water inlet joint and the water inlet of the shell, and a second sealing ring is provided between the nozzle seat bushing and the shell.

[0016] As described above, a rotary sprinkler with a buffer structure, the sprinkler assembly includes:

[0017] a riser housing having a riser cavity and a riser water inlet connecting the riser cavity and the housing cavity;

[0018] a riser movably disposed in the riser cavity along the length of the riser housing, wherein a riser passage communicating with the riser cavity is defined in the riser;

[0019] The nozzle has one end disposed on the riser and communicated with the riser channel, and the other end movably connected to the nozzle holder.

[0020] In the rotary sprinkler with a buffer structure as described above, the joint water outlet hole is arranged obliquely along the radial direction of the water inlet joint, and the water outlet of the joint water outlet hole is located on the side wall of the water inlet joint. The end of the water inlet joint close to the core housing is provided with a first conical contact surface, and the end of the core housing close to the water inlet joint is provided with a second conical contact surface that contacts the first conical contact surface. When water flows from the joint water outlet hole to the inner wall of the shell cavity, the water flowing along the inner wall of the shell cavity drives the core housing to rotate eccentrically, and the second conical contact surface rotates around the first conical contact surface.

[0021] In the rotary sprinkler with a buffer structure as described above, a riser outlet seat is provided in the riser channel, and a plurality of water diversion channels are provided on the riser outlet seat, which penetrate the riser outlet seat along the axial direction of the riser channel.

When in use, high-pressure water enters from the water inlet joint, enters the shell cavity through the water outlet hole of the joint, and then enters the sprinkler assembly. When the high-pressure water enters the sprinkler assembly, the impact of the water flow drives the sprinkler assembly to move toward the nozzle seat assembly and touch the push-up nozzle seat assembly. Since the elastic buffer element is provided between the shell and the nozzle seat assembly of the present application, the elastic buffer element is compressed when the push-up nozzle seat assembly plays a buffering and shock-absorbing role, thereby avoiding rigid collision between the sprinkler assembly and the nozzle seat assembly, reducing collision damage, and improving service life.

[0031] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] When the embodiments of the present invention mention ordinal numbers such as "first" and "second", unless they do express the meaning of order according to the context, they should be understood as being merely for the purpose of distinction.

[0033] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0034] Specific embodiments, such as Figure 1-3 The rotary sprinkler with a buffer structure shown in the figure includes: a shell 1, which is provided with a shell cavity 11, and a shell water inlet 12 and a shell water outlet 13 respectively connected to the two ends of the shell cavity 11; a water inlet joint 2, which is provided in the shell water inlet 12, and the water inlet joint 2 is provided with a joint channel 21 and a joint water outlet hole 22 connecting the joint channel 21 and the shell water inlet 12; a nozzle seat assembly 3, which is provided in the shell cavity 11 and connected to the shell water outlet 13; a nozzle assembly 4, which is provided in the shell cavity 11 and connected to the shell cavity 11, and one end is movably connected to the nozzle seat assembly 3; an elastic buffer element 5, which is provided between the shell 1 and the nozzle seat assembly 3. Optionally, the elastic buffer element 5 adopts a spring. When in use, high-pressure water enters from the water inlet joint, enters the shell cavity through the joint water outlet hole, and then enters the nozzle assembly. When the high-pressure water enters the nozzle assembly, the water flow impact drives the nozzle assembly to move toward the direction close to the nozzle seat assembly and touch the push-up nozzle seat assembly. Since an elastic buffer element is provided between the shell and the nozzle seat assembly of the present application, the elastic buffer element is compressed when the push-up nozzle seat assembly plays a buffering and shock-absorbing role, thereby avoiding rigid collision between the nozzle assembly and the nozzle seat assembly, reducing collision damage, and improving service life.

[0035] Specifically, the nozzle seat assembly 3 includes: a nozzle seat bushing 31, which is provided with a bushing through hole 311 connected to the water outlet 13 of the shell, and a nozzle seat mounting groove 312 connected to the bushing through hole 311, and the elastic buffer element 5 is arranged between the shell 1 and the nozzle seat bushing 31; the nozzle seat 32, which is arranged in the nozzle seat mounting groove 312, and one end is movably connected to the nozzle assembly 4, and the other end is connected to the bushing through hole 311.

[0036] Furthermore, the nozzle holder bushing 31 is provided with an elastic member mounting groove 6 around the bushing through hole 311. One end of the elastic buffer element 5 is mounted in the elastic member mounting groove 6, while the other end abuts against the housing 1. The elastic buffer element 5 is mounted within the elastic member mounting groove 6 and sleeved around the bushing through hole 311, resulting in a more compact structure, more uniform and stable compression buffering, and preventing the elastic buffer element 5 from separating from the nozzle holder bushing 31 during use.

[0037] Furthermore, a first sealing ring 71 is provided between the water inlet joint 2 and the water inlet 12 of the housing, and a second sealing ring 72 is provided between the nozzle seat bushing 31 and the housing 1. The housing cavity 11 is sealed to ensure high-pressure water outlet.

[0038] More specifically, the nozzle assembly 4 comprises a riser housing 41 defining a riser cavity 411 and a riser water inlet 412 connecting the riser cavity 411 with the housing cavity 11; a riser 42 movably mounted within the riser cavity 411 along the length of the riser housing 41. The riser 42 defines a riser channel 421 communicating with the riser cavity 411; and a nozzle 43, one end of which is mounted on the riser 42 and communicates with the riser channel 421, while the other end is movably connected to the nozzle holder 32. High-pressure water enters the riser cavity 411 through the riser water inlet 412, flows along the riser cavity 411, and draws the riser 42 toward the nozzle holder assembly 3, causing the nozzle 43 to push against the nozzle holder 32 and compressing the elastic buffer 5 between the nozzle holder bushing 31 and the housing. This reduces damage to the nozzle 43 and nozzle holder 32 caused by collision, thereby extending the service life of the nozzle 43.

[0039] Furthermore, the connector water outlet hole 22 is arranged radially and obliquely along the water inlet connector 2, with the outlet of the connector water outlet hole 22 located on the sidewall of the water inlet connector 2. A first conical contact surface 81 is provided on the end of the water inlet connector 2 proximal to the riser housing 41, and a second conical contact surface 82 is provided on the end of the riser housing 41 proximal to the water inlet connector 2, contacting the first conical contact surface 81. When water flows from the connector water outlet hole 22 toward the inner wall of the housing cavity 11, the water flowing along the inner wall of the housing cavity 11 drives the riser housing 41 to rotate eccentrically, and the second conical contact surface 82 rotates about the first conical contact surface 81. The water flow drives the eccentric rotation of the nozzle assembly to discharge water, resulting in a rational and simple structure.

[0040] Furthermore, a riser outlet seat 9 is disposed in the riser channel 421 , and a plurality of water diversion channels 91 are disposed on the riser outlet seat 9 and penetrate the riser outlet seat 9 along the axial direction of the riser channel 421 .

[0041] Specifically, a limiting retaining ring 101 is provided in the riser cavity 411 , a limiting groove 102 is provided on the outer wall of the riser 42 , and the limiting retaining ring 101 is located in the limiting groove 102 to limit the movement of the riser 42 along the water flow direction.

[0042] More specifically, a riser gasket 14 is provided at one end of the riser 42 away from the nozzle 43 , and a riser bushing 15 is provided at one end of the riser 42 close to the nozzle 43 . The diameter of the riser bushing 15 gradually decreases along the water flow direction.

[0043] In addition, the end of the riser housing 41 near the nozzle 43 is tilted outwardly along the radial direction of the riser 42 to prevent the riser housing 41 from interfering with the nozzle seat bushing 31 when the riser housing 41 rotates eccentrically.

[0044] The above is an implementation method provided in conjunction with specific content, and does not necessarily mean that the specific implementation of this utility model is limited to these descriptions. At the same time, due to differences in industry nomenclature, it is not limited to the above nomenclature, nor is it limited to English nomenclature. Any method, structure, etc. similar to or identical to the method, structure, etc. of this utility model, or any technical deduction or replacement based on the concept of this utility model, shall be considered within the scope of protection of this utility model.
