Abstract
Description
Technical Field
[0001] The invention relates to the technical field of sprinkler equipment, in particular to a multi-directional spray device for garden irrigation. Background Art
[0002] Under natural conditions, precipitation in the north is often insufficient and unevenly distributed, which can easily lead to water shortage for garden plants. In order to ensure the normal growth of garden plants, it is usually necessary to install irrigation sprinklers to supplement water.
[0003] However, when the water pressure of the existing spraying device is low, the spraying range of the spraying device will be reduced, thereby affecting the irrigation effect of the garden plants. Summary of the invention
[0004] Based on this, it is necessary to provide a multi-directional spray device for garden irrigation to address the technical problem that the current spray head has a small spray range when the water pressure is low.
[0005] The above purpose is achieved through the following technical solutions:
[0006] A multi-directional spray device for garden irrigation comprises a pipe network, wherein a valve is arranged on the pipe network, wherein the valve is used to control the water flow in the pipe network, wherein a plurality of spray pipes are arranged on the pipe network, wherein the spray pipe comprises a fixed cylinder, wherein the fixed cylinder extends in the up-down direction, wherein a telescopic spray head is slidably arranged inside the fixed cylinder, wherein the fixed cylinder is connected with the pipe network, wherein the water flow in the pipe network enters the fixed cylinder and can push the telescopic spray head to slide along the fixed cylinder, wherein a water spray port is arranged on the telescopic spray head, wherein the water spray port extends from the fixed cylinder and then sprays water outward, wherein a rotation drive mechanism and a resistance mechanism are arranged between the telescopic spray head and the fixed cylinder, wherein the rotation drive mechanism causes the telescopic spray head to rotate when sliding along the fixed cylinder, and wherein the resistance mechanism can limit the rotation angle of the telescopic spray head in the fixed cylinder; wherein the resistance mechanism in the plurality of spray pipes causes the maximum rotation angle of each telescopic spray head to be different, thereby causing the extension length of each telescopic spray head to be different.
[0007] Furthermore, a convex ring is provided at the bottom of the telescopic nozzle, and a plurality of protrusions are circumferentially spaced on the convex ring, and an upper gear ring and a lower gear ring are provided on the inner wall of the fixed cylinder, the upper gear ring includes a plurality of upper guide teeth spaced circumferentially, and the lower gear ring includes a plurality of lower guide teeth spaced circumferentially, and the upper guide teeth and the lower guide teeth are staggered along the circumference of the fixed cylinder, and the protrusions and the upper gear ring and the lower gear ring constitute the rotation drive mechanism.
[0008] Furthermore, the upper guide teeth and the lower guide teeth are both right-angled triangles, the upper guide teeth are provided with a first inclined surface, and the lower guide teeth are provided with a second inclined surface. When the telescopic nozzle slides upward, the protrusion slides with the first inclined surface to rotate the telescopic nozzle around the first direction. When the telescopic nozzle slides downward, the protrusion slides with the second inclined surface to rotate the telescopic nozzle around the first direction.
[0009] Furthermore, the first inclined plane and the second inclined plane have opposite inclination directions; when viewed from top to bottom, the first direction is clockwise.
[0010] Furthermore, the outer circumferential surface of the telescopic nozzle is provided with a plurality of rubber strips, and the rubber strips can be deformed along the radial direction of the telescopic nozzle. The inner circumferential surface of the fixed cylinder is provided with a plurality of arc-shaped gradient grooves connected end to end, and the rubber strips correspond to the arc-shaped gradient grooves one by one; in the first direction, the groove depth of the arc-shaped gradient groove gradually decreases, and the rubber strips and the arc-shaped gradient groove constitute the resistance mechanism.
[0011] Furthermore, the positions of the rubber strips in the plurality of spray pipes gradually change in the arc-shaped gradual groove.
[0012] Furthermore, a compression spring is provided between the bottom of the fixed cylinder and the convex ring of the telescopic nozzle. When the compression spring is in a naturally contracted state, the convex block is located between two adjacent lower guide teeth. When the compression spring is in a maximum stretched length, the convex block is located between two adjacent upper guide teeth.
[0013] Furthermore, the water spray port is arranged at the middle position of the telescopic nozzle, and when the extension length of the telescopic nozzle reaches the maximum, the water spray port extends from the fixed tube.
[0014] Furthermore, a water inlet is provided at the bottom of the fixed cylinder, and the water inlet is connected to the pipe network.
[0015] Furthermore, the top of the fixed cylinder is threadedly connected with an end cover, and the end cover is slidably matched with the telescopic nozzle.
[0016] The beneficial effects of the present invention are:
[0017] The multi-directional spray device for garden irrigation provided by the present invention has a low water pressure. Since the resistance mechanisms in the multiple spray pipes make the maximum rotation angles of the telescopic spray heads different, the water pressure can only make the telescopic spray heads in the spray pipes with low rotation resistance extend from the fixed tube, while the telescopic spray heads in the spray pipes with high rotation resistance cannot be extended from the fixed tube because they cannot rotate. In this way, some of the telescopic spray heads can spray water outward, while other telescopic spray heads cannot spray water. Compared with multiple spray pipes that can spray a smaller range, the spray range of the telescopic spray heads that can spray water is not affected, thereby ensuring the water spraying effect.
[0018] Secondly, when the water pressure is low, each time the valve is opened and closed, two of the spray pipes can spray water outward, and each time the spray pipes that spray water are different, which not only ensures the spray range but also improves the uniformity of the spray.

[0033] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0034] like Figures 1 to 10As shown, a multi-directional spray device for garden irrigation provided by one embodiment of the present invention includes a pipe network 100, a valve (not shown in the figure) is provided on the pipe network 100, and the valve is used to control the water flow in the pipe network 100. The pipe network 100 is provided with a plurality of spray pipes 200, and the spray pipes 200 include a fixed cylinder 202, and the fixed cylinder 202 extends in the up-down direction. A telescopic spray head 201 is slidably provided inside the fixed cylinder 202, and the fixed cylinder 202 is communicated with the pipe network 100. The water flow in the pipe network 100 enters the fixed cylinder 202 and can push the telescopic spray head 201 along the fixed cylinder 202. 02 slides, a water spraying port 2013 is arranged on the telescopic nozzle 201, and the water spraying port 2013 extends out from the fixed cylinder 202 and then sprays water outwards, a rotation drive mechanism and a resistance mechanism are arranged between the telescopic nozzle 201 and the fixed cylinder 202, the rotation drive mechanism makes the telescopic nozzle 201 rotate when sliding along the fixed cylinder 202, and the resistance mechanism can limit the rotation angle of the telescopic nozzle 201 in the fixed cylinder 202; the resistance mechanism in the multiple spray pipes 200 makes the maximum rotation angle of each telescopic nozzle 201 different, and thus the extension length of each telescopic nozzle 201 is different. The telescopic nozzle 201 is a cylindrical structure with a closed top.
[0035] In this way, when the water pressure is low, the water pressure can only make the telescopic nozzle 201 in the spray pipe 200 with low rotational resistance extend from the fixed tube 202, while the telescopic nozzle 201 in the spray pipe 200 with high rotational resistance cannot be extended from the fixed tube 202 because it cannot rotate. In this way, some of the telescopic nozzles 201 can spray water outward, while other parts of the telescopic nozzles 201 cannot spray water. Compared with multiple spray pipes 200 that can spray a smaller range, the spraying range of the telescopic nozzle 201 that can spray water is not affected, thereby ensuring the water spraying effect.
[0036] In one embodiment, a convex ring is provided at the bottom of the telescopic nozzle 201, and a plurality of protrusions 2012 are circumferentially spaced on the convex ring. An upper toothed ring and a lower toothed ring are provided on the inner wall of the fixed cylinder 202, and the upper toothed ring includes a plurality of upper guide teeth 205 spaced circumferentially, and the lower toothed ring includes a plurality of lower guide teeth 206 spaced circumferentially. The upper guide teeth 205 and the lower guide teeth 206 are staggered along the circumference of the fixed cylinder 202, and the protrusions 2012 and the upper and lower toothed rings constitute the rotation drive mechanism.
[0037] In one embodiment, the upper guide teeth 205 and the lower guide teeth 206 are both right triangles, the upper guide teeth 205 are provided with a first inclined surface 2051, and the lower guide teeth 206 are provided with a second inclined surface 2061. When the telescopic nozzle 201 slides upward, the protrusion 2012 slides with the first inclined surface 2051 to rotate the telescopic nozzle 201 around the first direction. When the telescopic nozzle 201 slides downward, the protrusion 2012 slides with the second inclined surface 2061 to rotate the telescopic nozzle 201 around the first direction. In this way, the telescopic nozzle 201 always rotates around the first direction when sliding upward or downward.
[0038] In one embodiment, the first inclined surface 2051 and the second inclined surface 2061 are inclined in opposite directions; when viewed from top to bottom, the first direction is clockwise.
[0039] In one embodiment, the outer circumference of the telescopic nozzle 201 is provided with a plurality of rubber strips 2011, and the rubber strips 2011 can be deformed along the radial direction of the telescopic nozzle 201. The inner circumference of the fixed cylinder 202 is provided with a plurality of arc-shaped gradient grooves 2022 connected end to end, and the rubber strips 2011 correspond to the arc-shaped gradient grooves 2022 one by one. In the first direction, the groove depth of the arc-shaped gradient grooves 2022 gradually decreases, and the rubber strips 2011 and the arc-shaped gradient grooves 2022 constitute the resistance mechanism. Since the telescopic nozzle 201 always rotates around the first direction, the rubber strips 2011 on the telescopic nozzle 201 will slide in the arc-shaped gradient grooves 2022, and after sliding to the end of the arc-shaped gradient grooves 2022, enter the head end of the next arc-shaped gradient groove 2022, so that the length of the rubber strips 2011 changes back and forth, thereby changing the rotation resistance between the rubber strips 2011 and the arc-shaped gradient grooves 2022.
[0040] In one embodiment, the positions of the rubber strips 2011 in the plurality of spray pipes 200 in the arc-shaped gradual groove 2022 gradually change. For example, among the five adjacently arranged spray pipes 200, the rubber strip 2011 in the first spray pipe 200 is located at the head end of the arc-shaped gradual groove 2022, with the smallest rotation resistance; the rubber strips 2011 in the second, third, and fourth spray pipes 200 are respectively located in the middle part of the arc-shaped gradual groove 2022, with moderate rotation resistance and gradually increasing; the rubber strip 2011 in the fifth spray pipe 200 is located at the end of the arc-shaped gradual groove 2022, with the largest rotation resistance.
[0041] In one embodiment, a compression spring 204 is provided between the bottom of the fixed cylinder 202 and the convex ring of the telescopic nozzle 201. When the compression spring 204 is in a naturally contracted state, the convex block 2012 is located between two adjacent lower guide teeth 206. When the compression spring 204 is at a maximum stretched length, the convex block 2012 is located between two adjacent upper guide teeth 205. This arrangement allows the convex block 2012 to always move up and down within the range of the upper and lower tooth rings and always be in a rotating state, so that the rubber strip 2011 on the telescopic nozzle 201 always slides along the arc-shaped gradient groove 2022.
[0042] In one embodiment, the water spray port 2013 is arranged in the middle of the telescopic nozzle 201, and when the extension length of the telescopic nozzle 201 reaches the maximum, the water spray port 2013 extends from the fixed tube 202. In this way, when the telescopic nozzle 201 extends to a small length, the water spray port 2013 is still located inside the fixed tube 202 and cannot spray water, so that a part of the spray pipe 200 can spray water, while another part of the spray pipe 200 does not spray water.
[0043] In one embodiment, a water inlet is provided at the bottom of the fixed cylinder 202, and the water inlet is connected to the pipe network 100. Water in the pipe network 100 enters the interior of the fixed cylinder 202 through the water inlet.
[0044] In one embodiment, the top of the fixed cylinder 202 is threadedly connected with an end cap 203, and the end cap 203 is slidably matched with the telescopic nozzle 201. The end cap 203 is detachably mounted on the fixed cylinder 202, which is convenient for repairing the spray pipe 200, and the end cap 203 is matched with the convex ring stopper of the telescopic nozzle 201 to prevent the telescopic nozzle 201 from being separated from the fixed cylinder 202.
[0045] In combination with the above embodiments, the use principle and working process of the embodiments of the present invention are as follows:
[0046] Open the valve on the pipe network 100, and let water flow into the pipe network 100, and the water flows into the interior of the fixed cylinder 202 through the water inlet. When the water pressure is high, the telescopic nozzles 201 inside all the spray pipes 200 can overcome the elastic force of the compression spring 204 and slide upward, and when the protrusion 2012 on the telescopic nozzle 201 slides upward to between two adjacent upper guide teeth 205 of the upper tooth ring, each telescopic nozzle 201 can rotate clockwise under the guidance of the first inclined surface 2051 of the upper guide tooth 205, and each rubber strip 2011 can rotate along the arc-shaped gradient groove 2022, so that the telescopic nozzle 201 inside each spray pipe 200 can extend the maximum length from the fixed cylinder 202, so that the water spray port 2013 extends from the fixed cylinder 202, and the water spray port 2013 irrigates the garden plants.
[0047] When the water pressure is low, the rotation resistance between the rubber strip 2011 and the arc-shaped gradient groove 2022 in the first to fifth spray pipes 200 gradually increases. The rubber strip 2011 in the first spray pipe 200 is located at the head end of the arc-shaped gradient groove 2022, and the rubber strip 2011 is compressed to the minimum, so the rotation resistance of the spray pipe 200 is the minimum; the rubber strip 2011 in the second, third, and fourth spray pipes 200 are all located in the middle part of the arc-shaped gradient groove 2022, so the rotation resistance of the spray pipe 200 is moderate and gradually increases; the rubber strip 2011 in the fifth spray pipe 200 is located at the end of the arc-shaped gradient groove 2022, and the rubber strip 2011 is compressed to the maximum, so the rotation resistance of the spray pipe 200 is the maximum.
[0048] At this time, the water pressure can only make the telescopic nozzles 201 in the first spray pipe 200 and the second spray pipe 200 slide and rotate upward along the first inclined surface 2051 of the upper guide tooth 205, and the rotation angle is large, so that the upward movement distance of the telescopic nozzle 201 can reach the maximum extension length, so that the water spray port 2013 extends from the fixed tube 202; while when the telescopic nozzles 201 in the third spray pipe 200 and the fourth spray pipe 200 slide and rotate upward along the first inclined surface 2051 of the upper guide tooth 205, the rotation angle is small, so that the upward movement distance of the telescopic nozzle 201 cannot reach the maximum extension length, so that the water spray port 2013 cannot extend from the fixed tube 202; and the telescopic nozzle 201 in the fifth spray pipe 200 cannot rotate and slide upward along the upper guide tooth 205 due to excessive rotation resistance, so that the water spray port 2013 cannot extend from the fixed tube 202. Therefore, under this water pressure, only the first spray pipe 200 and the second spray pipe 200 can spray water outward.
[0049] Then the valve on the pipe network 100 is closed, and the retractable nozzle 201 in each spray pipe 200 is reset downward under the elastic force of the compression spring 204, so that the protrusion 2012 on the retractable nozzle 201 slides downward and enters between the next two adjacent lower guide teeth 206 of the lower tooth ring in the clockwise direction, and each retractable nozzle 201 continues to rotate clockwise under the guidance of the second inclined surface 2061 of the lower guide teeth 206. At this time, the positions of the rubber strips 2011 in the first spray pipe 200 and the fifth spray pipe 200 in the arc-shaped gradient groove 2022 change, the rubber strip 2011 in the fifth spray pipe 200 enters the head end of the next adjacent arc-shaped gradient groove 2022, the rubber strip 2011 in the fourth spray pipe 200 is located at the end of the arc-shaped gradient groove 2022, and the rubber strips 2011 in the first, second and third spray pipes 200 are all located in the middle of the arc-shaped deformation groove.
[0050] Then, the valve on the pipe network 100 is opened again. Under the action of water pressure, only the telescopic nozzles 201 in the fifth spray pipe 200 and the first spray pipe 200 can slide and rotate upward along the first inclined surface 2051 of the upper guide tooth 205, and the rotation angle is large, so that the telescopic nozzle 201 can move upward to a maximum extension length, so that the water spray port 2013 extends out from the fixed tube 202; while the telescopic nozzles 201 in the second spray pipe 200 and the third spray pipe 200 slide and rotate upward along the first inclined surface 2051 of the upper guide tooth 205, the rotation angle is small, so that the telescopic nozzle 201 can not move upward to a maximum extension length, and the water spray port 2013 cannot extend from the fixed tube 202; and the telescopic nozzle 201 in the fourth spray pipe 200 cannot rotate and slide upward along the upper guide tooth 205 due to excessive rotation resistance, so that the water spray port 2013 cannot extend from the fixed tube 202. Therefore, under this water pressure, opening the valve again can only allow the fifth spray pipe 200 and the first spray pipe 200 to spray water outward.
[0051] In this way, when the water pressure is low, each time the valve is opened and closed, two of the spray pipes 200 can spray water outward, and the spray pipes 200 that spray water each time are different, which can not only ensure the spraying range, but also improve the spraying uniformity.
[0052] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0053] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
