Description

Technical Field

[0001] The utility model relates to a rotary sprinkler, in particular to a dual-purpose rotary sprinkler. Background Art

[0002] At present, sprinklers are required in garden greening irrigation. Its structure mainly includes a water inlet seat and a nozzle. The nozzle is fixed to the water inlet seat at a certain angle deviating from the vertical axis. The water inlet seat has a rotary gearbox seat, which can drive the water inlet seat to drive the nozzle to rotate around the vertical axis; in this way, water from the water source is first externally connected to the water inlet seat and then sprayed out from the nozzle in a rotating manner to form a sprinkling area. However, since the angle of the nozzle relative to the fixed seat cannot be adjusted, the area of the regional sprinkling cannot be adjusted either. Therefore, it can only be used as a rotary sprinkler for a single spraying area and cannot meet the needs of users for greening sprinkler irrigation in multiple areas and different area sizes; at the same time, if an angle adjustment design is required for the nozzle relative to the fixed seat, it will put higher requirements on the design of its internal water supply path, which not only needs to ensure the flexibility of the nozzle angle adjustment but also needs to ensure the smoothness and tightness of the internal water supply; in addition, multiple water-shaped holes are designed on the section flower cover that constitutes the nozzle component, and various water shapes can be selected according to actual use needs. However, the distance of the water shape ejected from each water-shaped hole is constant, that is, the distance and uniformity of the water spray cannot be adjusted, which also affects the use in some special occasions.

[0030] A dual-purpose rotating sprinkler, as Figures 1 to 8 shown, belongs to a sprinkler device in garden greening irrigation, and its structure includes a water inlet seat 1 and a sprinkler head 2.

[0031] Among them, the water inlet seat 1 is composed of a rotating gearbox seat 11 and a housing 12 covering the outside of the rotating gearbox seat. The rotating gearbox seat 11 can drive the housing 12 to rotate around the vertical axis, and further drive other components installed on the housing 12 to rotate synchronously around the vertical axis. The bottom end of the rotating gearbox seat 11 is designed with a water inlet joint, which can be used to connect a water pipe and connect the water source to the water inlet seat 1.

[0032] The water inlet seat 1 is provided with a water inlet channel 101. Specifically, a water inlet channel is vertically formed along the axis in the water inlet seat. An annular channel 102 is provided on the top surface of the water inlet seat 1, and a connecting channel 103 connecting the water inlet channel 101 and the annular channel is provided. Actually, both the annular channel 102 and the connecting channel 103 are arranged on the top surface of the housing 12.

[0033] The water inlet seat 1 is provided with a fixed seat 3. The fixed seat is a U-shaped seat, and a water inlet cavity 31 is arranged inside the fixed seat 3. Actually, the inside of the fixed seat 3 is hollow to form the water inlet cavity 31, and the water inlet cavity is hermetically connected to the annular channel 102. The two U-shaped ends of the fixed seat 3 are respectively provided with mounting holes 33 for the rotating shaft 4 to pass through and be installed, and a side hole 32 communicating with the water inlet cavity 31 is arranged on the hole wall of one of the mounting holes 33.

[0034] A swing seat 5 is arranged at the rear side of the spray head 2. The swing seat is installed on the fixed seat 3 through the rotating shaft 4 and forms multi-angle swing adjustment relative to the fixed seat 3 around the rotating shaft 4. In this way, when the swing seat 5 drives the spray head 2 to swing vertically upward relative to the fixed seat 3, ground spraying can be formed, or when the swing seat 5 drives the spray head 2 to deviate from the vertical, multi-directional area watering can be adjusted by swinging.

[0035] The rotating shaft 4 is a cylindrical horizontal shaft with a hollow interior and closed ends. Therefore, a water outlet channel 41 can be arranged inside the hollow rotating shaft 4. The water outlet channel includes a horizontal channel 411 arranged along the axial direction inside the rotating shaft, a side channel 412 arranged at one end of the rotating shaft and communicating with the horizontal channel at the same time, and a middle channel 413 arranged in the middle of the rotating shaft and communicating with the horizontal channel. When the two ends of the rotating shaft 4 respectively pass through and are installed in the mounting holes 33 at the two U-shaped ends of the fixed seat 3, and the side channel 412 and the side hole 32 are exactly at the same end, the side channel 412 can be hermetically connected to the water inlet cavity 31 through the side hole 32, so that the water inlet cavity is connected to the water outlet channel 41.

[0036] A seat shell 6 is provided outside the swing seat 5 and is fixedly covered. The seat shell and the swing seat are provided with a swing hole 52 that is coaxially penetrated and allows the rotating shaft 4 to pass through and be installed.

[0037] A water outlet cavity 51 is arranged inside the swing seat 5. Actually, the inside of the swing seat is hollow to form the water outlet cavity. The rotating shaft 4 passes through and is installed in the swing hole 52 of the swing seat 5, and the middle channel 413 is directly communicated with the water outlet cavity 51.

[0038] The spray head 2 includes a water outlet seat 21, a water outlet plate 22 and a section flower cover 23 that are coaxially connected by screws. The water outlet seat, the water outlet plate and the section flower cover are all circular sheet-like components. The water outlet seat 21 is fixedly installed on the swing seat 5. The section flower cover 23 and the water outlet plate 22 are fixedly installed, and the section flower cover and the water outlet plate form a fixed-angle rotation relative to the water outlet seat 21. Specifically, an elastic positioning bead 7 is arranged between the water outlet seat 21 and the water outlet plate 22, and the water outlet plate 22 forms a fixed-angle rotation relative to the water outlet seat through the elastic positioning bead 7, thereby driving the section flower cover 23 to synchronously rotate at a fixed angle.

[0039] The described water outlet base 21 is provided with a water outlet hole 211, and this water outlet hole is hermetically communicated with the water outlet cavity 51; the water outlet plate 22 is provided with a plurality of water spraying holes 221 that are distributed in a circular pattern with the rotation axis as the center of the circle, and the section flower cover 23 is provided with a plurality of water shape holes 231. The plurality of water shape holes are in one-to-one correspondence and communication with the plurality of water spraying holes on the water outlet plate. In this embodiment, a total of six water spraying holes 221 and water shape holes 231 that are in one-to-one correspondence and communication are designed, so that the spray head 2 has the use functions of six water shapes.

[0040] Obviously, the water inlet channel 101, the water inlet cavity 31, the water outlet channel 41, the water outlet cavity 51, and the water shape holes 231 can be hermetically communicated in sequence to form the internal water supply path of the rotating sprinkler.

[0041] When the section flower cover 23 and the water outlet plate 22 rotate at a certain angle relative to the water outlet base 21, they can drive the plurality of water spraying holes 221 to selectively communicate with the water outlet hole 211, and then various water shapes are sprayed out from the water shape holes 231 that are in one-to-one correspondence and communication. A water sealing ring 10 is fixedly embedded in the water outlet hole 211, which can play a sealing role when the water outlet hole 211 selectively communicates with the plurality of water spraying holes 221.

[0042] Therefore, this rotating sprinkler designed by the present utility model not only solves the structural design of the angle adjustment of the spray head 2 relative to the fixed seat 3, but also can ensure the smoothness and tightness of the internal water supply, so as to be able to flexibly adjust the sprinkling area of the area, achieving the two functions of conventional spraying and rotating water birds, thus having the use characteristics of a dual-purpose type and meeting the greening sprinkling and watering needs of users in multiple areas and different area sizes.

[0043] The section flower cover 23 is provided with a water pressing seat 8 and a water pressing plate 9. The water pressing seat 8 movably passes through the rotation axes of the section flower cover 23 and the water outlet plate 22 and is fixed on the water outlet base 21. The specific structure is as follows: a cylindrical shaft platform 212 is provided at the axis of the water outlet base 21, and this shaft platform is fitted in the circular shaft hole 24 at the rotation axes of the section flower cover 23 and the water outlet plate 22. The water pressing seat 8 is also fitted in the shaft hole 24 through a shaft sleeve 81, and the shaft sleeve 81 and the shaft platform 212 are fixed by a screw 25, that is, the water pressing seat 8 is fixed on the shaft platform 212 through the screw 25. Thus, the water pressing seat 8 is fixed to the water outlet base 21. Therefore, when the section flower cover 23 rotates, since the water outlet base 21 does not rotate, the corresponding water pressing seat 8 will not rotate either, so the section flower cover 23 can rotate relative to the water pressing seat 8, and the water pressing plate 9 axially reciprocates relative to the water pressing seat 8.

[0044] The described segment flower cover 23 and the water outlet plate 22 rotate at a fixed angle relative to the water outlet seat 21, enabling the water pressure seat 8 and the water pressure plate 9 to select corresponding water-shaped holes 231. Then, by axially reciprocating the water pressure member 9 relative to the water pressure seat 8, the shielding area of the corresponding water-shaped hole 231 can be adjusted, thereby adjusting the distance and uniformity of the water spray of the corresponding water-shaped hole 231, thus meeting the usage requirements in some special occasions. In addition, these water-shaped holes 231 are directly designed on the segment flower cover 23, which is different from the traditional water-shaped holes with a welded structure, and the usage structure is also more reliable.

[0045] The above are only specific embodiments of the present invention. Those skilled in the art should understand that any structural design equivalent to this embodiment should be included within the protection scope of the present invention.
