[0046] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0047] like Figure 1 , 2 As shown in Figures 4 and 5, the utility model provides a duckbill nozzle with automatic flow adjustment, including a nozzle assembly 1 and an adjustment assembly 2, the nozzle assembly 1 including a nozzle 11, the nozzle 11 having a liquid inlet 11a and a liquid spraying port 11b; the adjustment assembly 2 includes a sliding member 21, an adjustment member 22 and a driving member 23, the sliding member 21 is slidably arranged on the nozzle 11, the adjustment member 22 is movably arranged on the liquid spraying port 11b and connected to the sliding member 21, and the driving member 23 connects the sliding member 21 and the nozzle 11, and is used for driving the adjustment member 22 to slide relative to the liquid spraying port 11b via the sliding member 21 to adjust the opening size of the liquid spraying port 11b.

[0048] When liquid enters the nozzle 11 from the liquid inlet 11a, the liquid will be sprayed out through the liquid spray port 11b; in order to adjust the amount of liquid sprayed, the driving member 23 is started, and the driving member 23 drives the sliding member 21 to slide relative to the nozzle 11, and the nozzle 11 drives the adjusting member 22 to slide relative to the liquid spray port 11b, so as to adjust the opening size of the liquid spray port 11b. When the opening size of the liquid spray port 11b is reduced, the amount of liquid sprayed can be reduced; when the opening size of the liquid spray port 11b is increased, the amount of liquid sprayed can be increased.

[0049] It should be understood that the driving member 23 can be a manually adjustable bolt, which connects the nozzle 11 and abuts the adjusting member 22, and drives the adjusting member 22 to slide by sliding the bolt; it should be understood that the opening size of the spray port 11b can be adjusted manually, or by electric, pneumatic and hydraulic methods.

[0050] It should be understood that the adjusting member 22 may be a sliding block, a sliding bar, a sliding rod, etc. that slides into or out of the liquid spraying port 11 b along the sliding direction of the sliding member 21 .

[0051] It should be understood that the liquid spraying port 11b of the nozzle 11 can be in various shapes, such as arc, fan, long strip, etc. Specifically, Figure 3 As shown, the liquid ejection port 11b of the nozzle 11 is fan-shaped.

[0052] like Figure 1 and Figure 4As shown, in one embodiment, the driving member 23 includes a hinged portion 231 and a linear driving portion 232, one side of the hinged portion 231 is hinged to the nozzle 11, the hinged portion 231 abuts against the sliding member 21, and the linear driving portion 232 has a fixed end and a telescopic end, the fixed end of the linear driving portion 232 is hinged to the nozzle 11, and the telescopic end of the linear driving portion 232 is hinged to the hinged portion 231, and the linear driving portion 232 is used to drive the hinged portion 231 to rotate, so as to drive the sliding member 21 to slide relative to the nozzle 11 through the rotating hinged portion 231.

[0053] The linear drive part 232 (such as an electric push rod, a cylinder, etc.) drives the hinge part 231 by extending and retracting the telescopic end. When the telescopic end of the linear drive part 232 is extended, the hinge part 231 rotates around the axis of the hinge with the nozzle 11; when the telescopic end is shortened, the hinge part 231 rotates in the opposite direction. When the hinge part 231 rotates, it can push the sliding member 21 to slide relative to the nozzle 11. The sliding of the sliding member 21 will drive the adjustment member 22 connected thereto to move, thereby changing the opening size of the liquid spraying port 11b to adjust the liquid spraying amount.

[0054] like Figure 1 and Figure 5 As shown, in one embodiment, the sliding member 21 includes at least one sliding portion 211 and a connecting portion 212 , at least one sliding portion 211 is slidably disposed on the nozzle 11 , and the connecting portion 212 is connected to a side of the sliding portion 211 away from the nozzle 11 ; the hinged portion 231 abuts against the connecting portion 212 .

[0055] The sliding part 211 is slidably disposed on the nozzle 11, so that the sliding part 21 can slide smoothly on the nozzle 11. The connecting part 212 is connected to the side of the sliding part 211 away from the nozzle 11, and is used to abut against the hinge part 231; the hinge part 231 rotates under the drive of the linear drive part 232, thereby pushing the connecting part 212 abutting against it. Since the connecting part 212 is connected to the sliding part 211, the thrust of the hinge part 231 causes the sliding part 211 to slide along the nozzle 11.

[0056] It should be understood that the number of the sliding parts 211 can be one, two or more. When the number of the sliding part 211 is one, the radial cross-section of the sliding part 211 is polygonal; the connecting part 212 can be a connecting strip, a connecting block, a connecting rod, etc.

[0057] like Figure 1 and Figure 5 As shown, in one embodiment, the hinge portion 231 is formed with at least two abutting portions 233 , and the at least two abutting portions 233 are connected to the hinge portion 231 and are spaced apart at both sides of the connecting portion 212 .

[0058] When the hinged portion 231 rotates forward, the hinged portion 231 pushes the connecting portion 212 through an abutting portion 233, and pushes the connecting portion 212 to slide in a direction close to the nozzle 11; when the hinged portion 231 rotates reversely, the hinged portion 231 pushes the connecting portion 212 through another hinged portion 231, and pushes the connecting portion 212 to slide in a direction away from the nozzle 11.

[0059] By providing two abutting portions 233 and arranging the two abutting portions 233 on both sides of the connecting portion 212 , when the hinged portion 231 rotates, it can approach or move away from the nozzle 11 through the two abutting portions 233 .

[0060] It should be understood that the number of the abutting portions 233 may be two, three, four, or more.

[0061] It should be understood that the connecting portion 212 may abut against two abutting portions 233 at the same time, or may be spaced apart from the two abutting portions 233 so that the connecting portion 212 can move between the two abutting portions 233 .

[0062] like Figure 1 and Figure 5 As shown, in one embodiment, at least two abutting portions 233 abut against the connecting portion 212 respectively, and the side surfaces of the abutting portions 233 abutting against the connecting portion 212 are both arc surfaces.

[0063] By having both abutting portions 233 abut against the connecting portion 212, the connecting portion 212 can be prevented from shaking between the two abutting portions 233; at the same time, since the two abutting portions 233 respectively abut against the connecting portion 212, when the abutting portions 233 rotate under the drive of the hinge portion 231, the abutting portions 233 push the connecting portion 212 to move, and at the same time, they rotate relative to the connecting portion 212 through the arc surface, so that the connecting portion 212 can slide under the push of the abutting portions 233.

[0064] like Figure 4 and Figure 6 As shown, in one embodiment, the nozzle 11 is provided with at least one sliding hole 11d, and the sliding part 211 is slidably disposed in the sliding hole 11d. It should be understood that the sliding member 21 can also be slidably connected to the nozzle 11 through a slide rail, a sliding hole 11d, etc.

[0065] The sliding hole 11 d is provided to achieve a sliding connection between the sliding portion 211 and the nozzle 11 .

[0066] like Figure 4 and Figure 6 As shown, in one embodiment, the number of the sliding holes 11d is at least two, and the at least two sliding holes 11d are parallel and spaced apart. The number of the sliding parts 211 is at least two, and the at least two sliding parts 211 are respectively slidably disposed in the at least two sliding holes 11d.

Such a design makes the sliding of the sliding member 21 on the nozzle 11 more stable.

[0068] like Figure 1 As shown, in one embodiment, at least one guide sleeve 12 is formed on one side of the nozzle 11 , and the sliding portion 211 is slidably disposed on the guide sleeve 12 .

[0069] By providing the guide sleeve 12 , it is possible to provide guidance for the sliding of the sliding portion 211 , so that the sliding portion 211 can slide stably.

[0070] It should be understood that the guide sleeve 12 corresponds to the sliding hole 11d one by one and is coaxially arranged.

[0071] like Figure 1 As shown, in one of the embodiments, a fixing portion 13 is formed on one side of the nozzle 11; the linear drive portion 232 is spaced apart from one side of the nozzle 11 to form an installation space, and a fixed end of the linear drive portion 232 is hinged to the fixing portion 13 and is hinged to the nozzle 11 via the fixing portion 13.

[0072] By setting the fixing part 13, the linear driving part 232 can be hinged to the nozzle 11 through the fixing part 13. At this time, an installation space is formed between the nozzle 11 and the linear driving part 23, and the installation space can be used for the installation of the guide sleeve 12, the connecting part 212 and the sliding part 211.

[0073] It should be understood that the fixing portion 13 may be a fixing block, a fixing rod, a fixing bar, etc.

[0074] like Figure 5 As shown, in one embodiment, the sliding portion 211 is detachably connected to the adjusting member 22 .

[0075] By detachably connecting the sliding part 211 and the adjusting member 22, when installing the adjusting member 22, the sliding part 211 and the adjusting member 22 can be installed separately, which is convenient for installation of the sliding part 211 and the adjusting member 22, and the sliding part 211 can be replaced as needed after being used for a certain number of years.

[0076] like Figure 6 As shown, in one embodiment, the liquid spraying port 11b of the nozzle 11 forms a slide groove 11c, and the adjusting member 22 is slidably disposed in the slide groove 11c.

[0077] By sliding the adjusting member 22 in the slide groove 11c, when the linear driving part 232 drives the adjusting member 22 to slide out of the slide groove 11c through the hinge part 231, the abutting part 233, the connecting part 212 and the sliding part 211, the effective liquid outlet area of ​​the liquid spraying port 11b is reduced; when the linear driving part 232 drives the adjusting member 22 to slide into the slide groove 11c through the hinge part 231, the abutting part 233, the connecting part 212 and the sliding part 211, the effective liquid outlet area of ​​the liquid spraying port 11b is increased; the size of the liquid spraying port 11b is adjusted by sliding.

[0078] It should be understood that the adjusting member 22 may be a block, an arc-shaped strip, etc. distributed along the length direction of the liquid injection port 11b.

[0079] like Figure 4 As shown, in one embodiment, a sealing ring 14 is disposed between the interior of the slide groove 11 c and the adjusting member 22 , and the sealing ring 14 is disposed around the adjusting member 22 .

[0080] By setting, the sealing ring 14 can seal the gap between the slide groove 11c and the adjusting member 22 to prevent water from flowing out through the gap between the adjusting member 22 and the slide groove 11c.

[0081] It should be understood that the sealing ring 14 can be embedded in the peripheral wall of the adjusting member 22 and slide against the inner wall of the slide groove 11 c , or the sealing ring 14 can be embedded in the inner wall of the slide groove 11 c , and the inner ring slides against the peripheral wall of the adjusting member 22 .
