The sprinkling head 2 is provided at an upper end of the pedestal 1. The pedestal 1 includes a socket 11, a first water stop ring 12, a housing 13, and a second water stop ring 14.

Description

  The present invention relates to a water sprinkling nozzle, and in particular, can be placed on the ground or inserted or buried on the surface of the water to make water discharge and spraying into one fan-shaped region, and can change and adjust the water distribution pattern. The present invention relates to a nozzle device.

  This type is a watering nozzle capable of adjusting and changing water discharge, such as US Pat. No. 4,579,285, US Pat. No. 5,205,491, US Pat. No. 5,556,036 and US Pat. No. 6,443,372, US Pat. No. 6,769,633. In general, these include a housing that can be connected to a water source at one end forming an opening, and a spreading head with one outlet located in the housing. Among these, several perforations communicating with the inside are formed on the upper surface of the hollow housing, and a central platform having a screw hole in the center is formed. Moreover, the spreading head fixed to a housing can be couple | bonded with a hollow housing. The spray head is provided with an upper lid and a lower lid, and the end surfaces of the upper lid and the lower lid are formed in a conical shape relative to each other. A spiral surface is formed in the conical portion, and a difference in height between the end points of the spiral surface can be used as a stopper. In addition, a screw hole is provided opposite to this, and the stud bolt passes through the screw hole and is coupled to the inside of the housing. When the upper lid of the spraying head rotates and moves toward the end towards the lower lid, the spiral surface of the upper lid closes the outlet of the lower lid, and at the same time, two spiral surfaces provided on the two oppositely designed spiral surfaces The stoppers also touch each other and block. Since the outlet is closed by the top lid, the water entering from the bottom end of the housing cannot pass through each perforation and then blow out from the outlet, which is a “no water spray” condition. Further, when the upper lid is rotated in the opposite direction, the lower lid opens the outlet, and the change in the fan-shaped angle of the water sprayed from the outlet can be selected.

Further, US Pat. No. 6,769,633 is composed of a main body, an adjustment ring, a top cover and a restricting screw, the characteristics of which are as follows. The main body is an approximately hollow cylindrical body, an annular body is provided at an approximately central position on the inner side, and is connected to the hollow cylindrical body by several connecting pieces, and the upper end of the hollow cylindrical body Is provided with a layer edge. The adjustment ring is an annular body formed by connecting and installing a nut tube with several connecting pieces on the lower side, and a tooth-like helical protrusion is formed on the opening edge of the upper end surface of the annular body. A ring is provided, and an opening-like slope is provided at the inner edge of the projecting ring. The upper lid is an approximately funnel-type lid, and a screw and a socket are sequentially provided at the center of the lower stage, and a through-hole penetrating the entire lid is provided at the center. Several grooves are provided in the peripheral wall of the socket at intervals, and an annular protrusion is provided on the outer edge of the end of the socket.
The adjustment ring is directly attached to the hierarchical edge of the main body, and the screw of the upper lid is inserted into the nut tube of the adjustment ring, and the socket at the lower end of the screw is inserted into the annular body of the main body. The projecting ring of the socket is locked to the lower edge end surface of the annular body and positioned, and the three members of the main body, the adjustment ring, and the upper lid can be combined together. Finally, a restricting screw is inserted into the screw of the upper lid and the through hole of the socket from the lower side of the main body so as to prevent the socket from being reduced or pulled out.

  However, these cited references are for a water channel having the same width from the inner diameter of the lower lid to the outlet diameter, in other words, the water discharge pressure is directly released from this water channel. The opposing water channels do not evenly distribute the water pressure, fan-shaped spraying results in a non-uniform distribution of water volume, and the spiral surfaces at the two relative positions of the upper and lower lids are gradually opened. The size of the annular water discharge gap is different. Therefore, fan-shaped spraying results in an uneven state where the splash is large or small.

  In order to prevent this kind of situation from occurring, the condition of such a watering nozzle is improved. The spiral surface of the upper lid and the spiral surface of the lower lid are provided with tooth-like or step-like structures, respectively, and the fan-shaped spraying is evenly distributed by these tooth-like or step-like structures. However, this raises another problem. When the matching degree of the spiral surfaces of the upper and lower lids is insufficient, the spiral surfaces of the upper and lower lids cannot be effectively brought into close contact with each other, and the opening / closing function of the spray head can be achieved. Failure to do so may cause the spray head to leak.

  Further, U.S. Pat. No. 6,443,372 is an improvement of the structure of the sprinkler nozzle, and its features are as follows. The lid body is provided with a step-like annular convex body along the bottom edge of the first spiral surface, and the outer periphery of the circular pipe body at the bottom end of the lid body is directly molded into a screw thread, and the threaded portion of the lower main body is Can be fixed and combined. The upper main body is a portion close to the upper end surface, and a third spiral surface corresponding to the second spiral surface extends from the inside of the tube wall, and the inner surface of the third spiral surface has a stepped shape in the lid. The larger outer diameter of the annular convex body can be just inserted and brought into close contact. Further, the vertical step surface formed by the height of the third spiral surface projects and extends the first water stop piece upward at the highest point of the spiral surface, and the inner surface of the first water stop piece is extended. An inclined surface is provided in the direction. Further, the second blocking piece is provided at the wall surface position of the inner diameter of the third spiral surface relative to the position of the first blocking piece. In addition, a localization projection is provided on a predetermined portion of the inner tube wall of the upper body. The main feature of this proposal is that the lid body is provided with a larger outer diameter of a step-like annular convex body that fits and adheres to the inner diameter of the third spiral surface along the bottom edge of the first spiral surface. It is to prevent water leakage and water leakage. However, as a problem that arises, when a larger outer diameter of the step-like annular convex body is fitted and brought into close contact with the inner diameter of the third spiral surface, it may be too close and in contact with each other.

  Therefore, the present invention improves the structure of the spray head. The purpose is mainly to improve the defect that water discharge is uneven in the spraying area of the spraying head, and to make the water flow adjusted by adjusting the spraying range of the spraying head more uniform.

The end surface of the second retaining wall 224 also has a helical conical surface 224a corresponding to the helical conical surface 223a of the first retaining wall 223, and the first retaining wall 223 is provided outside the collar 22, The wall 224 is provided inside the first retaining wall 223. Further, a protrusion 224 b is provided on one end face of the second retaining wall 224, and the protrusion 224 b is a slope, and the inclination height thereof is higher than the helical conical surface 224 a of the second retaining wall 224. The second retaining wall 224 described above forms the first water discharge channel 226 a and the spiral convex rib 225, and the spiral convex rib 225 is provided on the inner diameter of the second retaining wall 224. More precisely, the helical convex rib 225 surrounds the inner diameter of the second retaining wall 224. The recess 228a is provided on the bottom surface of the connecting portion 228 of the collar 22, which is a recess 228a on the bottom surface of the connecting portion 228 formed between the two enclosures of the first retaining wall 223 and the second retaining wall 224. The bottom surface of the recess 228a is planar.

  The adjusting member 24 is provided with a control unit 241, a contact unit 242, an assembly unit 243, a recess 245, a through hole 243a, and a rib 245a. The contact unit 242 includes the first contact surface 242a, the second contact surface 242b, and the first contact surface 242b. It has three contact surfaces 242b ′. The first contact surface 242 a is a spiral weight surface, and the contact portion 242 is extended from the control portion 241. A through hole 243a is provided in the assembly portion 243, and a female screw 243b is provided on the inner diameter of the through hole 243a. The second contact surface 242b is a concave arc-shaped helical weight surface, and the maximum diameter of the second contact surface 242b can exactly match the diameter of the first water discharge channel 226a of the collar 22. Further, a third contact surface 242b 'is formed at the end of the second contact surface 242b. By combining the first retaining wall 223 and the second retaining wall 224 of the collar 22 and the spiral convex rib 225, the water discharge state of the first water discharge channel 226a can be closed or adjusted. Further, the recess 245 is formed on the outer diameter of the assembly portion 243, and a rib 245 a is provided on one side of the annular wall of the recess 245.

  A protrusion 251 is provided on the fastener 25, and several grooves 252 are provided on the protrusion 251. By providing the grooves 252, several ribs having elasticity are formed on the protrusion 251. That is, the protruding edge 251 is formed from several elastic ribs, and the elastic ribs surround the perforations 251a.

  In particular, the spiral weight surface of the first contact surface 242a turns from a low part to a high part. Further, the second contact surface 242b is a concave arc-shaped helical weight surface swiveled from a low part to a high part, a third contact surface 242b 'is formed at the bottom end thereof, and the third contact surface 242b' It is a spiral surface.

  In response to the above, the shapes of the first contact surface 242a and the second contact surface 242b match the shapes of the first retaining wall 223 of the collar 22 and the helical conical surfaces 223a and 224a of the second retaining wall 224. More specifically, the second water discharge gap B and the third water discharge gap C can be formed simultaneously by rotating the adjusting member 24 in the radial direction. In other words, when the adjusting member 24 is rotated, the radial widths of the second water discharge gap B and the third water discharge gap C are widened, or the radial widths of the second water discharge gap B and the third water discharge gap C are reduced. You can select the change in the angle of water sprayed in a fan shape.

  Its features are as shown in FIG. When viewed from above, the second retaining wall 224 of the collar 22 has a tube wall 226, and the tube wall 226 forms a first water discharge channel 226a. Among these, the spiral convex rib 225 is provided on the tube wall 226, and the spiral convex rib 225 surrounds in the radial direction to form the tube wall 226. As shown in FIG. 5, when the collar 22 is viewed from below, it can be confirmed that the indentation 228a, the first convex rib 227a and the second convex rib 227b are provided, and the spiral convex rib 225 is formed on the bottom surface of the indentation 228a. It is confirmed that the tube wall 226 is stretched and formed.

  Subsequently, the assembly method of the spraying head 2 is as follows in order. The threaded portion 214 of the base 21 is passed through the second retaining wall 224 of the collar 22, and then the fitting portion 215 at one end of the threaded portion 214 is inserted into the through hole 243 a of the adjustment member 24, The joint portion 215 is protruded from the assembly portion 243 and screwed into the female screw 243b of the through hole 243a. Further, when the fitting portion 215 is inserted into the protruding edge 251 of the fastener 25, the fitting portion 215 expands by expanding the diameter of the perforation 251a due to the elasticity of the protruding edge 251. When the fitting portion 215 passes through the perforation 251a, the perforation 251a of the projecting edge 251 returns to the original diameter, and thereby the fastener 25 restricts the position of the fitting portion 215. Since the outer diameter of the fastener 25 is larger than the assembly portion 243 and the base 21 is engaged with the assembly portion 243, the base 21 can be engaged with the collar 22 and the adjustment member 24. In other words, the fastener 25 and the enlarged portion 211 of the base 21 tighten the adjustment member 24 and the collar 22 up and down, so that the combination is not separated. Finally, the gap portion 262 of the cover cap 26 is made to correspond to the rib 245 a of the adjustment member 24 and then overlapped with the recess 245.

  In the spraying head 2, the operation of adjusting the water discharge angle of the fan-shaped circumference is as follows. When the adjustment member 24 is rotated in the radial direction, a height difference is formed in which the end points of the two opposing spiral surfaces of the first retaining wall 223 of the collar 22 and the first contact surface 242a of the adjustment member 24 are the third water discharge gap C. The second retaining wall 224 and the second contact surface 242b form a height difference that is the second water discharge gap B. Among these, the protrusion 224b is a retaining wall that separates one open angle of the second water discharge gap B. By rotating the adjusting member 24 in the radial direction, the opposing spiral surfaces gradually shift, and the second water discharge gap B and the third water discharge gap C, which are height differences, gradually expand and expand, and one fan-shaped circumference A spray pattern is produced that is drained at As shown in FIGS. 8 and 8-1, the maximum circumferential angle of water discharge is about 360 ° C. When the adjustment member 24 is rotated in the opposite direction, the two opposing spiral surfaces of the second retaining wall 224 and the second contact surface 242b are gradually adapted, and at the same time, the two relative surfaces of the first retaining wall 223 and the first contact surface 242a are The spiral surfaces that fit gradually become partly overlapping. As shown in FIG. 9, most of the water discharge can be closed, the fan-shaped circumferences overlap in the radial direction, and most of the water discharge is closed. The second water discharge gap B and the third water discharge gap C indicate a minimum water discharge state, and the circumferential angle can be set to 5 degrees or less. As described above, the user rotates the adjustment member 24 based on the required circumferential angle of the water discharge.

  In addition, regarding the even distribution of the spraying and the water discharge state according to the present invention, when the adjusting member 24 is rotated to the water discharge state of 360 degrees, the water flow enters the water flow passage 213 of the base from the water channel space 131a of the base 1, and further the collar 22 Enters the first drainage channel 226a. At this time, when the water flow first enters from the spiral convex rib 225, it flows from the first water discharge gap A to the first water discharge path 226a, further passes through the second water discharge gap B, and finally flows out from the third water discharge gap C. Be guided. Among these, the spiral convex rib 225 and the third contact surface 242b 'are displaced from each other, and a high and low drop that is the open state of the first water discharge gap A is formed. From the partially enlarged view of FIG. 8A, the guidance of the water flow into the water discharge state first passes through the first water discharge gap A, and then is distributed evenly twice through the second water discharge gap B, and finally the first contact. It can be more clearly confirmed that the water is sprayed and discharged along the third water discharge gap C of the surface 242a and the first retaining wall 223.

  In particular, the description relates to the spiral surfaces corresponding to each other of the spiral convex rib 225 and the third contact surface 242b '. When the adjusting member 24 is rotated, the spiral convex rib 225 and the third contact surface 242b 'can generate a height difference, and this height difference is the first water discharge gap A of the first water discharge path 226a. At this time, a height difference is also formed between the two opposing spiral surfaces of the second retaining wall 224 of the collar 22 and the second contact surface 242b of the adjustment member 24. When the protrusion 224b reaches the first contact surface 242a, a separation end for opening and closing the second water discharge gap B is formed. In other words, by rotating the adjusting member 24 in the radial direction, the two opposing spiral surfaces of the spiral convex rib 225 and the third contact surface 242b 'can be gradually shifted to form the first water discharge gap A. Accordingly, the water flow is first evenly distributed and distributed by the first water discharge gap A, then passes through the second water discharge gap B, and then flows out along the third water discharge gap C in one upwardly inclined fan-shaped surface. A pattern is produced. The discharge angle of the fan-shaped circumference in this type of discharge can reach up to 360 degrees. Further, as shown in FIG. 9, when the adjusting member 24 is rotated in the opposite direction, the two opposing spiral surfaces of the first retaining wall 223 and the first contact surface 242a are gradually adapted, and at the same time, the spiral convex ribs 225 and Most of the two opposing spiral surfaces of the third contact surface 242b ′ overlap closely. Thus, most of the first water discharge gap A, the second water discharge gap B, and the third water discharge gap C can be closed, and the water discharge angle of the fan-shaped circumference of the third water discharge gap C is reduced. The minimum water discharge angle of the fan-shaped circumference can be reduced to 5 degrees or less.

  As described above, the water flow is sprayed from the spraying head 2 to the flowers and discharged. First, the water flow is first dispersed and distributed by the first water discharge gap A between the spiral convex rib 225 and the third contact surface 242b ', so that the water is first distributed and distributed circumferentially for the first time. Furthermore, the 2nd contact surface 242b is concave arc shape, The water which flows out can also be guide | induced more smoothly by the feature of the concave arc shape. Thus, when moving from the first water discharge gap A to the second water discharge gap B, the water flow is induced to change in an arc shape, the second distribution is performed, and the finally distributed water is the third water discharge gap C. Are distributed along the circumference, sprayed on the flowers, and discharged.

  In response to the above, the first retaining wall 223 provided in advance on the collar 22 is a spiral conical surface 223a designed to be inclined outward, and the convex portion 223b provided thereon also surrounds the spiral conical surface 223a. The spiral conical surface 223a of the first retaining wall 223 and the protrusion 224b of the second retaining wall 224 form one water retaining wall that separates the connecting portion 228, and this is opposed to the first contact surface 242a and the upper and lower spirals. It can contact | abut by an edge wall. More precisely, the convex portion 223b can reach the first contact surface 242a, and the convex portion 223b adopts an arc-shaped design, and thus has an arc-shaped guide surface. Can be made smoother. As another explanation, when water is sprayed and discharged from the spray head, the water flow is distributed and discharged by one or more water discharge gaps. The water flow is distributed by the first water discharge gap A between the spiral convex rib 225 and the third contact surface 242b ′, and then by the second water discharge gap B formed between the second contact surface 242b and the second retaining wall 224. Finally, the water is evenly distributed in a circumferential shape, and water is discharged along the third water discharge gap C of the first contact surface 242a and the first retaining wall 223, and is distributed to the flowers.

  In addition, what is particularly described relates to having an open gap 224 c between the protrusion 224 b of the second retaining wall 224 and the first retaining wall 223. The opening gap 224c can release some of the water pressure entering the connecting portion 228, and further the water flow, the distribution becomes more even, and the splashing is not large or small in the water discharge and spraying state. .

Among these, the spraying head 2 includes an adjustment member 24, a collar 22, a base 21 and a fastener 25. The adjustment member 24 is provided with a control part 241 and a contact part 242, and the contact part 242 has a first contact surface 242a and a second contact surface 242b. The bottom end of the concave arcuate assembly portion 243 is extended from the first contact surface 242a, and the second contact surface 242b is formed. The axis of the control part 241 extends downward to the contact part 242 to form a through hole 243a. A female screw 243b is provided at the upper end of the through hole 243a, and the screw contact part 214 of the base 21 is inserted and screwed. The
