Abstract
Description
[Technical Field]
[0001] The present invention relates to a sprinkler assembly capable of changing the sprinkling pattern, and more particularly to a water discharge device capable of changing the sprinkling pattern. [Background technology]
[0002] Conventionally, a sprinkler capable of changing the sprinkler pattern has a water supply pipe formed inside its main body, a water discharge plate pivotally connected to the front end of the main body, and multiple water discharge structures formed on the water discharge plate, with the water supply pipe corresponding to one of the selected water discharge structures.By rotating the water discharge plate, the water discharge structure that corresponds to and communicates with the axial direction of the water supply pipe can be switched, making it possible to change to different sprinkler patterns.
[0003] Assuming that the water spray is not stopped, as the water spouting plate is rotated, a lateral misalignment gradually occurs between the water spray structure of the water supply pipe, which has a corresponding axial direction, and the water supply pipe, and some of the water that flows out through the water supply pipe flows laterally and enters the main body, and is no longer able to pass through the water spray structure and be sprayed outward.By continuously rotating the water spouting plate, the correspondence range between the water spray structure and the water supply pipe gradually decreases, and the amount of water that is no longer able to be sprayed outward and enters the main body gradually increases.It is expected that the water will switch to another adjacent water spray structure so that it completely corresponds to the water supply pipe.When the water spraying form change is completed, it will be possible to eliminate the phenomenon where some water is no longer able to be sprayed outward and enters the main body. Summary of the Invention [Problem to be solved by the invention]
[0004] A portion of the water that passes through the water supply pipe enters the main body and flows out to the outside through the water outlet structure that does not correspond to the other water supply pipes, causing water stagnation problems at the installation location of the sprinkler.
[0005] A main object of the present invention is to provide a water discharge device that can change the water discharge pattern. [Means for solving the problem]
[0006] To achieve the above objectives, the present invention adopts the following technical solutions: [Effects of the Invention]
[0007] The main effect and advantage of the present invention is that during the operation process of changing the sprinkler form, the water flow is blocked by each of the blocking sections, so it does not flow sideways but enters the inside of the shell-shaped connecting member, thereby increasing the water utilization rate of the sprinkler and avoiding the problem of water stagnation that occurs at the installation location of the sprinkler.

[0009] As shown in Figures 1 to 9, a preferred embodiment of such a water-discharge device capable of changing the spray pattern comprises a connecting member 10 with a shell-shaped structure, a water-discharge member 20 with a disk-shaped structure, and a blocking structure 30, of which the connecting member 10 is used to form part of the main body of the water sprinkler, which may be a mobile water sprinkler gun or a fixedly installed water sprinkler, a circular mounting portion 12 is formed at the front end of the connecting member 10, a water supply pipe 14 is formed inside the connecting member 10, one end of the water supply pipe 14 is connected to a flow path for guiding the flow of water inside the main body, so that water passes through the water supply pipe 14 and flows out, and a virtual axis L1 is defined along the axial direction of the mounting portion 12 and passing through the radial center of the mounting portion 12, and the axial direction of the water supply pipe 14 is offset from the axis L1.
[0010] The water-discharging member 20 has a middle plate 21 and an annular portion 22, and the middle plate 21 is connected to the inner edge of the annular portion 22, and the annular portion 22 is annularly attached to the installation portion 12, so that the water-discharging member 20 can be rotated relative to the connecting member 10 based on the axis L1. A first water-discharging structure 23, a second water-discharging structure 24, and several third water-discharging structures 25 are formed on the middle plate 21, and a virtual circular line L2 is defined. The axis L1 passes through the center of the circular line L2, and the first water-discharging structure 23, the second water-discharging structure 24, and each of the third water-discharging structures 25 are arranged at intervals along the circular line L2, and the first water-discharging structure 23 and the second water-discharging structure 24 are arranged adjacent to each other along the circumferential direction of the circular line L2.
[0011] Each of the third water-discharging structures 25 is configured to be selectively positioned according to the radial dimension of the middle plate 21, and the number (quantity) of the third water-discharging structures 25 may be increased or decreased as needed, and is not limited to that exemplified in the preferred embodiment.
[0012] The axial direction of the water supply pipe 14 is selectively connected to the first water discharge structure 23, the second water discharge structure 24, or any one of the third water discharge structures 25. In FIGS. 3 and 5, the axial direction of the water supply pipe 14 is shown to be connected to the first water discharge structure 23. The axial direction of the water supply pipe 14 is sequentially changed as the water discharge member 20 is rotated so that the axial direction is connected to the second water discharge structure 24 or each of the third water discharge structures 25. As a result, water passes through the water supply pipe 14 and is connected to the first water discharge structure 23, the second water discharge structure 24, and the third water discharge structure 25. Or the water selectively passes through any one of the third water-spouting structures 25 and is sprayed outward, and the first water-spouting structure 23, the second water-spouting structure 24 and each of the third water-spouting structures 25 each have an unequal number of water-spouting holes 26, ranging from one to several, and the number (quantity), shape or hole diameter of the water-spouting holes 26 formed in the first water-spouting structure 23, the second water-spouting structure 24 and each of the third water-spouting structures 25 are different, so that different spray patterns are formed by passing water through the first water-spouting structure 23, or the second water-spouting structure 24, or each of the third water-spouting structures 25.
[0013] The water discharge member 20 has an existing structure that is well known to those skilled in the art in the technical field to which the present invention pertains.
[0014] The blocking structure 30 is connected to the water supply pipe 14, and a passage 31 communicating with the water supply pipe 14 is formed through the blocking structure 30, two blocking sections 32 are formed in the blocking structure 30, the passage 31 is located between each of the blocking sections 32, each of the blocking sections 32 and the passage 31 is arranged along a circumferential direction based on the axis L1, and the blocking structure 30 is elastically abutted against the water outlet member 20.
[0015] An exemplary explanation of the operation process for changing the spray pattern is as shown in Figures 6 to 9, as the water-discharging member 20 rotates, the axial direction of the first water-discharging structure 23 is gradually displaced away from the center of the passage 31, and the axial direction of the second water-discharging structure 24 is gradually brought closer to the center of the passage 31, and the operation for switching the spray pattern is completed when the axial direction of the second water-discharging structure 24 corresponds to the center of the passage 31. During the operation process, the first water-discharging structure 23 is gradually blocked by the blocking portion 32 located on one side of the passage 31, and the second water-discharging structure 24 gradually approaches and communicates with the passage 31, and the other side of the passage 31 is opened in the second water-discharging structure 24. The portion blocked by the blocking portions 32 located on the side gradually decreases, and as a result, during the operation process of rotating the water-discharging member 20 to change the spray pattern, after the water flows and passes through the passage 31, it is blocked by each of the blocking portions 32 and enters the inside of the shell-shaped connecting member 10 without flowing sideways, and the water does not flow out toward the outside through the first water-discharging structure 23, the second water-discharging structure 24, or any one of the third water-discharging structures 25 that do not correspond to the other passages 31, so it is possible to increase the water utilization rate of the spray and avoid the problem of water stagnation that occurs at the installation location of the sprinkler.
[0016] The blocking structure 30 is formed in an arc-shaped sector structure, and the axis L1 passes through the center of the blocking structure 30.
[0017] As shown in Figure 4, two imaginary first lines L3 are defined, each perpendicular to the axis L1, and each of the first lines L3 passes through the axis L1 and one end of each blocking portion 32 far from the passage 31 in the arc direction of the blocking structure 30, forming a first included angle θ1 between the first lines L3. Two imaginary second lines L4 are defined, each perpendicular to the axis L1, and each of the second lines L4 is tangent to both sides of the radial outer periphery of the passage 31, forming a second included angle θ2 between the second lines L4.
[0018] As shown in Figure 2, two imaginary third lines L5 are defined, each perpendicular to the axis L1, and each of the third lines L5 is tangent to both sides of the radial outer periphery of the first water-discharging structure 23, forming a third included angle θ3 between each of the third lines L5.Two imaginary fourth lines L6 are defined, each perpendicular to the axis L1, and each of the fourth lines L6 is tangent to both sides of the radial outer periphery of the second water-discharging structure 24, forming a fourth included angle θ4 between each of the fourth lines L6.
[0019] The first included angle θ1 is equal to or greater than the sum of the second included angle θ2, the third included angle θ3, and the fourth included angle θ4.
[0020] The water supply pipe 14 is encircled around the radial outer periphery of the blocking structure 30, and a tension retaining spring 40 is provided inside the water supply pipe 14. The blocking structure 30 is positioned between the tension retaining spring 40 and the water discharge member 20, with one end of the tension retaining spring 40 abutting against the connecting member 10 and the other end abutting against the blocking structure 30, thereby providing elasticity and facilitating the blocking structure 30 to be held in tight contact with the water discharge member 20.
[0021] The blocking structure 30 includes a positioning part 33 and a water-stopping part 34, of which the tension retaining spring 40 is held in contact with the positioning part 33, several protruding pillars 35 are protruding from the positioning part 33, and each of the protruding pillars 35 is arranged at intervals on the radial outer periphery surrounding the tension retaining spring 40, thereby positioning the tension retaining spring 40, the water-stopping part 34 is externally fitted onto the positioning part 33, and the water-stopping part 34 is located on the side of the positioning part 33 facing the water-discharge member 20, each of the blocking portions 32 is formed in the water-stopping part 34, and the passage 31 is formed to pass through the positioning part 33 and the water-stopping part 34, and the water-stopping part 34 is made of a material having elasticity.
[0022] The connecting member 10 is formed with a shaft pillar 16 , and the tension holding spring 40 is axially mounted on the shaft pillar 16 .
[0023] The blocking structure 30 has one first leakage prevention portion 36 and two second leakage prevention portions 37 formed on the side facing the water-discharging member 20, and the elastic first leakage prevention portion 36 and each of the second leakage prevention portions 37 are each elastically abutted against the water-discharging member 20, the annular first leakage prevention portion 36 is closely adjacent to the edge of the blocking structure 30, each of the second leakage prevention portions 37 is closely adjacent to both sides of the passage 31, and each of the second leakage prevention portions 37 is each connected to the first leakage prevention portion 36, and the first leakage prevention portion 36 and each of the second leakage prevention portions 37 are each formed integrally with the water-stopping component 34.
[0024] When the axial direction of the passage 31 is in communication with the first water-discharge structure 23, the second water-discharge structure 24, or any one of the third water-discharge structures 25, the axial direction of the passage 31 is aligned with the portion where each second leakage prevention portion 37 is located between each second leakage prevention portion 37 of the first leakage prevention portion 36, so that water passes through the passage 31 and enters the first water-discharge structure 23, the second water-discharge structure 24, or any one of the third water-discharge structures 25, thereby enhancing the effect of preventing lateral leakage, and during the operation process of rotating the water-discharge member 20 to change the spray pattern, the portion formed in each blocking portion 32 of the first leakage prevention portion 36 can enhance the effect of preventing water from flowing sideways and entering the connecting member 10.
