Description

Sprinkler with variable watering direction

The present invention relates to a device for sprinkler irrigation; in particular, it discloses an innovative structural form of a sprinkler device capable of changing the sprinkler direction.

A sprinkler pipe is known, one end of which is connected to a water source and the other end is closed. The sprinkler pipe is radially penetrated by multiple outlet holes, each of which connects to a channel inside the sprinkler pipe for water to flow through and to the environment outside the sprinkler pipe. Water from the water source flows along the channel toward the end of the sprinkler pipe, and the water is then distributed through each outlet hole to spray onto the exterior of the sprinkler pipe.

In actual use, the sprinkler pipe has been found to have the following problems and drawbacks: The spatial position of each outlet hole relative to the axial direction of the sprinkler hole determines the direction in which the water flows through each outlet hole and is then sprayed externally. To change the direction of the spray, the sprinkler pipe must be replaced with another one with a different outlet hole configuration. This leaves room for improvement in terms of usability.

The primary purpose of this invention is to provide a sprinkler device with variable watering direction. The technical problem it seeks to solve is to explore innovative breakthroughs in developing a new, more ideal and practical sprinkler device.

Based on the above-mentioned purpose, the technical features of the present invention for solving the problem mainly lie in the water sprinkling device with variable water sprinkling direction, comprising: a water pipe, a channel formed inside the water pipe, one axial end of the water pipe is defined as a first end, and the other axial end of the water pipe is defined as a second end, the first end closes one end of the channel, and the other end of the channel extends to the second end, so that water enters the channel through the second end and flows toward the first end, the water pipe is expanded in the radial direction to form a stop portion, the radial periphery of the water pipe is spaced to form two annular embedded grooves, each of which is located between the first end and the stop portion, and a water outlet is formed on the side of the water pipe to connect to the channel, and the water outlet is located at each end. The two water stop rings are respectively encircled around the radial periphery of the water pipe, and each of the water stop rings is partially embedded in each of the embedded grooves; a water guide ring is rotatably encircled around the water pipe, and the annular inner edge of the water guide ring abuts against each of the water stop rings, and a water-containing space is formed between the water guide ring, the water pipe and each of the water stop rings. The water guide ring is along the diameter A through hole is formed in the direction of the water pipe, the water containing space is connected to the water outlet and the through hole, so that the water is sprayed outward through the water outlet, the water containing space, and the through hole; a blocking member is removably connected to the radial outer periphery of the water pipe, the water guide ring is located between the blocking member and the stop portion, and the blocking member and the stop portion respectively form a stop for the water guide ring.

The main effect and advantage of this invention lies in the fact that by rotating any of the water-guiding collars, the orientation of the resulting through-hole can be changed, thereby changing the direction of water spraying and improving ease of use.

The figures show an embodiment of the sprinkler device of the present invention with variable sprinkler direction. However, these embodiments are for illustrative purposes only and are not intended to limit the scope of patent applications to this structure.

As shown in Figures 1 to 5, the first embodiment of the variable-direction sprinkler device includes a water pipe 10, a plurality of water guide rings 20, a water stop ring 32 twice the number of the water guide rings 20, and a blocking member 40. A channel 50 is formed within the water pipe 10. One axial end of the water pipe 10 is defined as a first end 11, and the other axial end of the water pipe 10 is defined as a second end 12. The first end 11 closes one end of the channel 50, and the other end of the channel 50 extends to the second end 12, so that the water body (not shown) can be directed to the channel 50. ) enters the channel 50 through the second end 12 and flows along the channel 50 toward the first end 11. The water pipe 10 is radially expanded to form a stopper 13. The water pipe 10 is radially expanded to form a plurality of annular grooves 14 spaced apart to match the number of water stop rings 32. Each groove 14 is located between the first end 11 and the stopper 13. The water pipe 10 is laterally formed with a plurality of water outlets 15 to connect to the channel 50, each located between two of the grooves 14, in accordance with the number of water guide rings 20.

Each of the water-stop rings 32 surrounds the radial outer periphery of the water pipe 10, and each of the water-stop rings 32 is partially embedded in each of the embedding grooves 14.

Each of the water guide rings 20 is rotatably encircled around the water pipe 10, and each of the water guide rings 20 is sequentially arranged along the axial direction of the water pipe 10. The annular inner edge of each of the water guide rings 20 abuts against two of the water stop rings 32. A plurality of water spaces 60 are formed in each of the water guide rings 20, the water pipe 10, and the water stop rings 32. Between the two water stop rings 32 against which the water guide rings 20 abut, each water guide ring 20 has a through hole 22 extending radially therethrough. Each water-receiving space 60 is connected to a water outlet 15 and a through hole 22, allowing water to be sprayed outward through each water outlet 15, each water-receiving space 60, and each through hole 22.

The number of water-conducting collars 20 can be increased or decreased as needed, but is limited to at least one. The number of water-stop rings 32 can also be increased or decreased to at least two, and the number of water outlets 15 and water-containing spaces 60 can also be increased or decreased to at least one, respectively.

The blocking member 40 is removably connected to the radial periphery of the water pipe 10. Specifically, the blocking member 40 is threaded onto the water pipe 10. Each of the water-conducting collars 20 is positioned between the blocking member 40 and the stopper 13. The blocking member 40 and the stopper 13 respectively block each of the water-conducting collars 20 sequentially arranged axially along the water pipe 10.

With the blocking member 40 not connected to the water pipe 10, first install each water stop ring 32 onto the water pipe 10, then install each water guide ring 20 onto the water pipe 10 in sequence. Finally, screw the blocking member 40 onto the water pipe 10 to complete the installation of each water guide ring 20.

The water flows along the channel 50 and is laterally divided and flows through each of the water outlet holes 15 into each of the water holding spaces 60, and then sprays outward through each of the through holes 22. Since each of the water holding spaces 60 is respectively annularly surrounding the radial periphery of the water pipe 10, even if each of the through holes 22 is not opposite to each of the water outlet holes 15 in the radial direction of the water pipe 10, the water can still be respectively sprayed outward through each of the water holding spaces 60. Water in the space 60 flows radially outward along the water pipe 10, then exits each water guide collar 20 through the through-holes 22 and is sprayed outward. Users can rotate any of the water guide collars 20 as needed to change the orientation of the through-holes 22, thereby changing the direction of water spraying without having to replace the water pipe 10 with a different configuration of the water outlet holes 15, thus improving ease of use.

As shown in Figures 6 to 8 , the main difference between the second embodiment and the first embodiment lies in that every two adjacent water-stop rings 32 are integrally connected to a baffle 34, thereby forming a plurality of water-stop structures 30. Each baffle 34 closely abuts the water pipe 10 and a water-conducting collar 20, thereby selectively blocking the connection between each water-containing space 60 and its corresponding through-hole 22. The number of baffles 34 increases or decreases in accordance with the number of water-conducting collars 20.

By rotating any selected water-conducting collar 20 so that the through hole 22 formed therein aligns with the baffle 34, water cannot be sprayed outward through the through hole 22. This allows one or more outward spraying paths to be selectively closed, making it easy to adjust the spraying direction and area.

As shown in Figures 9 to 12 , the structure of the third embodiment differs from that of the first embodiment in that the channel 50 extends to the first end 11 and the second end 12, respectively. The water pipe 10 forms a first anchor structure 16 and a second anchor structure 17. The first anchor structure 16 is located on the pipe wall 18 of the water pipe 10 surrounding the channel 50 and connected to the first end 11. The second anchor structure 17 is located on the radial periphery of the water pipe 10 and connected to the second end 12.

The first and second anchor structures 16 and 17 are each configured with threads, and the first and second anchor structures 16 and 17 form a male-female fit with each other.

The user can choose to sequentially connect several third embodiments to form a sprinkler pipe 01. In this case, the first joint structure 16 of one water pipe 10 is threadedly connected to the second joint structure 17 of another adjacent water pipe 10, and the first end 11 of one water pipe 10 abuts the stopper 13 of another adjacent water pipe 10.

A blocking member 40 is removably connected to the water pipe 10 at one end of the sprinkler pipe 01 and seals the first end 11 of the water pipe 10. Specifically, the blocking member 40 is threadedly connected to the first joint structure 16 of the water pipe 10. The blocking member 40 expands radially to form a blocking portion 42. The diameter of the blocking portion 42 is larger than the outer diameter of the adjacent water pipe 10. The adjacent water guide ring 20 is located between the blocking portion 42 and the stop portion 13. The blocking portion 42 and the stop portion 13 each block the water guide ring 20.

As shown in Figure 13, the fourth embodiment differs from the third embodiment primarily in that the water supply pipe 10 includes a turning section 19 located between the stop 13 and the first end 11. Figure 14 illustrates the fourth embodiment coupled to two third embodiments. This turning section 19 facilitates configuration of the sprinkler pipe 01 to suit environmental requirements.

The third and fourth embodiments can each be provided with the baffle 34 disclosed in the second embodiment, thereby forming different alternative embodiments, and the aforementioned alternative embodiments have the water-stop structure 30 disclosed in the second embodiment.
