Description

Technical field

[0001] The invention relates to a sprinkler and in particular a multi-stage sprinkler for individual control of the water flow. State of the art

[0002] A typical sprinkler has a spray tube with numerous spray openings. A swivel mechanism and the water pressure of the incoming water cause the spray tube to oscillate, thus changing the spray angle of the openings.

[0003] To meet various requirements, a separate switch is provided for each spray outlet to precisely control the spray pattern. However, the large number of such switches can lead to leaks. Due to infrequent use and the potential for leaks in sealing elements, the sprinkler's lifespan is reduced. Furthermore, each switch requires sufficient installation space, meaning that one switch for each individual spray outlet reduces the distribution density of multiple spray outlets and consequently impairs the spray density. Description of the invention

[0004] The main object of the present invention is to provide a multi-stage sprinkler for individual control of the water flow. To achieve the aforementioned purpose, the following technical solution is used in the present invention: Multi-stage sprinkler for individual control of water flow, including: a base; A swivel control that oscillates in response to the water pressure of the water flow; the swivel control is detachably connected to the base and coupled to a pipe connector; the pipe connector can be connected to a water supply line through which the water is introduced; an elongated spray housing, one end of which is pivotably attached to the base and the other end of which is connected to the swivel control, wherein the spray housing is driven by the swivel control and pivots oscillatingly relative to the base and has several nozzles spaced apart along its longitudinal extent; wherein the spray housing forms a main chamber, one end of which is connected to the pipe connector via the swivel control, and forms several sub-chambers along its longitudinal extent, each sub-chamber being connected to the main chamber and several nozzles, and each nozzle being connected to only one sub-chamber; Several ball valves, each located in the spray housing between the main chamber and an associated sub-chamber, control whether the sub-chamber is connected to or separated from the main chamber in order to individually control the water flow in several sections.

[0005] The invention can form several sections, each from which water can exit separately, thus enabling a variety of spray modes. The adequate installation space required for the arrangement of the ball valve does not lead to a reduction in the distribution density of multiple spray openings and does not impair the spray density.

Designs

[0006] The exemplary embodiments of the multi-stage sprinkler for individual control of the water flow, explained below with reference to the drawings, serve exclusively for illustrative purposes and do not limit the scope of protection of the claims.

[0007] As in the Fig. As shown in Figures 1 to 5, the first embodiment of a multi-stage sprinkler according to the invention for individual control of the water flow comprises a base (10), a pipe connector (20), a swivel control (30), and an elongated spray housing (40). The pipe connector (20) can be connected to a water supply line (90) through which water from a remote water source (not shown in the drawings) is introduced into the first embodiment. The swivel control (30) is detachably connected to the base (10) and coupled to the pipe connector (20). The swivel control (30) causes an oscillating rotary movement via the water pressure of the incoming water.

[0008] The swivel control (30) is a device known to those skilled in the art, which drives the spray housing (40). A detailed description of the swivel control (30) is therefore unnecessary.

[0009] The spray housing (40) is elongated; one end is pivotally connected to the base (10), the other end is connected to the swivel control (30). The spray housing (40) is driven by the swivel control (30) and swivels in an oscillating motion relative to the base (10). Along its longitudinal extent, the spray housing (40) has several nozzles (41) at intervals.

[0010] The spray housing (40) forms a main chamber (42). One end of the main chamber (42) is connected to the pipe connector (20) via the swivel control (30). Several sub-chambers (43) are formed along the longitudinal extent of the spray housing (40). Each sub-chamber (43) is connected to the main chamber (42) and to several nozzles (41), with each nozzle (41) being connected to only one sub-chamber (43).

[0011] Several ball valves (50) are arranged in the spray housing (40). Each ball valve (50) is located between the main chamber (42) and an associated sub-chamber (43) and controls whether this sub-chamber (43) is connected to or separated from the main chamber (42), so that the water flow is individually controlled in several sections.

[0012] The base (10) serves to position the swivel control (30) and the spray housing (40). When the spray housing (40) is moved in an oscillating manner by the swivel control (30), the embodiment can be positioned stably in the area to be irrigated.

[0013] As in Fig. As shown in Figure 7, several subchambers (43) are each connected to the main chamber (42). Together with the ball valves (50), these form several sections, each from which water exits. Each ball valve (50) controls whether and in what quantity the multiple nozzles (41) of the associated subchamber (43) release water. This allows for a variety of spray modes; for example, water can be sprayed through multiple nozzles (41), or through adjacent or separate nozzles (41). Furthermore, each ball valve (50) controls several nozzles (41) together, thus reducing the number of ball valves (50) required. The required installation space for the ball valves (50) is not affected by their dimensions and does not reduce the nozzle density (41), so the spray density remains unaffected.

[0014] The spray housing (40) comprises a tube housing (44) and a tubular insert (45). One end of the tube housing (44) is pivotally connected to the base (10). The insert (45) is arranged within the tube housing (44) and connected to it. The insert (45) forms the main chamber (42), which is connected to the pivot control (30). The insert (45) and the tube housing (44) together form the sub-chambers (43). The nozzles (41) are arranged on the tube housing (44).

[0015] Each ball valve (50) has a first rotary knob (51) and a spherical part (52). The first rotary knobs (51) are used to actuate the ball valves (50) by turning them. The first rotary knobs (51) are each arranged on one side of the tube housing (44). The spherical parts (52) are each pivotally and tightly connected to the mounting body (45) so that each spherical part (52) separates the lower chamber (43) corresponding to its associated ball valve (50) from the main chamber (42). Each spherical part (52) has a radially extending through-opening (53) that connects the lower chamber (43) corresponding to its associated spherical part (52) to the main chamber (42). Each spherical part (52) forms a first connecting section (54) that is connected to the first rotary knob (51) of its ball valve (50).Thus, the spherical parts (52) are each rotated by the first rotary knobs (51) to control the connection state between the sub-chambers (43) and the main chamber (42).

[0016] The installation body (45) has several channels (46) on its sides. The first rotary knobs (51) and the channels (46) are located on opposite sides of the installation body (45). Each channel (46) is assigned to a ball valve (50), and the inner diameter of each channel (46) corresponds to the outer diameter of the respective spherical part (52), so that the spherical parts (52) can be inserted into the installation body (45) through the channels (46).

[0017] Several closure elements (60) are each connected to the installation body (45). Each closure element (60) closes a channel (46) and is pivotally connected to a spherical part (52) to position the respective ball valves (50). In the first embodiment, the closure elements (60) are connected to the installation body (45) by means of high-frequency welding, so that the water flowing into the installation body (45) cannot escape to the outside through any of the channels (46).

[0018] The assembly of the spray housing (40) and the ball valves (50) is carried out as follows: The insert body (45) is not yet inserted into the tube housing (44) and the channels (46) are not yet closed by the sealing elements (60); the first rotary knobs (51) and the spherical parts (52) of the ball valves (50) are separated from each other; each spherical part (52) is inserted into the insert body (45) through a channel (46); then the sealing elements (60) are each connected to the insert body (45) so that the channels (46) are closed; after that, the insert body (45) is inserted into the tube housing (44) through one end of the tube housing (44); then each first rotary knob (51) is connected from the outside through the tube housing (44) to a first connecting section (54) of the associated spherical part (52);In this way, several ball valves (50) are formed, thus completing the assembly of the spray housing (40) and the ball valves (50).

[0019] The user can intuitively control, via the rotation angles of each first rotary knob (51), whether the nozzles (41) assigned to the respective ball valve (50) dispense water and in what quantity. This increases the ease of use when controlling water dispensing and water flow.

[0020] The installation body (45) has several annular first sealing elements (72), several annular second sealing elements (74), and several third sealing elements (76). Each first sealing element (72) is arranged between a spherical part (52) and the subchamber (43) corresponding to the spherical part (52) and bears elastically against the corresponding spherical part (52) and the installation body (45).

[0021] Every second sealing element (74) surrounds a ball valve (50) and is located between the spherical part (52) and the first rotary knob (51) of the ball valve (50). Every second sealing element (74) bears elastically against the ball valve (50) it surrounds and the mounting body (45).

[0022] Each third sealing element (76) is located on the side of the subchambers (43) facing the tube housing (44) and rests elastically against the installation body (45) and the tube housing (44).

[0023] The spray housing (40) has several markings (47), each corresponding to a ball valve (50). Each marking (47) is assigned to the nozzles (41) that correspond to the ball valve (50) in order to identify the irrigation area assigned to the respective ball valves (50).

[0024] As in the Fig.As shown in Figures 8 to 10, the second embodiment differs from the first embodiment essentially in that the ball valves (50) each have an additional second rotary knob (55) for rotating the ball valves (50). These second rotary knobs (55) are each arranged on the tubular housing (44). The spherical parts (52) each form a second connecting section (56), which is connected to the second rotary knob (55) of the associated ball valve (50) through a closing element (60). The spherical parts (52) are thus rotated by the respective second rotary knobs (55) to control the connection state between the respective sub-chambers (43) and the main chamber (42).

[0025] The installation body (45) further comprises several ring-shaped fourth sealing elements (78).

[0026] Each fourth sealing element (78) surrounds a ball valve (50) and is located between the spherical part (52) and the second rotary knob (55) of the ball valve (50). Each fourth sealing element (78) bears elastically against the ball valve (50) it surrounds and the mounting body (45).

[0027] The invention relates to a multi-stage sprinkler for individual control of water flow. It comprises a base, a swivel control, and a spray housing. The swivel control is connected to the base and a pipe connector through which water is supplied. One end of the spray housing is pivotally mounted to the base, and the other end is connected to the swivel control; the spray housing is driven by the swivel control and pivots in an oscillating motion relative to the base. The spray housing carries several nozzles at intervals. A main chamber and several sub-chambers are formed within the spray housing. The main chamber is connected to the pipe connector via the swivel control. Each of the sub-chambers is connected to the main chamber and to several nozzles.

[0028] Several ball valves are arranged in the spray housing, with each ball valve controlling whether the associated sub-chamber is connected to or separated from the main chamber, so that the water flow can be individually controlled in several sections.
