Description

Technical Field

[0001] This utility model relates to the field of duckbill nozzle technology, specifically to a duckbill nozzle device. Background Technology

[0002] A duckbill nozzle is a type of nozzle that produces a uniform, wide, and moderately impactful fan-shaped water curtain, rather than a traditional cone-shaped spray. This unique fluid pattern gives it irreplaceable advantages in various cleaning, cooling, and irrigation scenarios. It is often used for washing vehicles.

[0003] CN222535223U discloses a flow-adjustable duckbill nozzle, including a nozzle assembly, an adjustment assembly, and a drive assembly. The nozzle assembly includes a nozzle with a connected liquid inlet and a liquid outlet, and the inner wall of the liquid outlet is provided with a groove. The adjustment assembly includes an adjustment part that is slidably disposed in the groove. The drive assembly connects the nozzle and the adjustment part and is used to drive the adjustment part to slide relative to the groove to adjust the length of the adjustment part sliding into the liquid outlet.

[0004] The nozzles mentioned above have a threaded interface at the water inlet. Duckbill nozzles are generally connected to the water outlet pipe via a threaded interface, flange, or bolts. However, when the nozzle needs to be disassembled via a threaded interface or flange, it is necessary to rotate the nozzle multiple times or remove the bolts to remove the nozzle in order to replace it with a different model of nozzle, which makes nozzle disassembly inconvenient. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a duckbill nozzle device to solve the technical problem of inconvenient nozzle disassembly in the prior art.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a duckbill nozzle device, comprising: A fixed pipe having an inlet channel for fluid to pass through, and a groove being formed on the outer wall of the fixed pipe; A liquid spraying assembly includes a sleeve and a nozzle. The sleeve is fitted onto the fixed pipe, the nozzle is connected to the sleeve, and the inlet end of the nozzle is connected to the inlet channel of the fixed pipe via the sleeve. The disassembly assembly includes an eccentric component rotatably connected to the sleeve and capable of rotatably embedding into and abutting the inner wall of the slot, and capable of pushing the nozzle to conform to the fixed pipe. The eccentric component can also rotate to disengage from the slot.

[0007] In one embodiment, the disassembly assembly further includes a handle connected to the eccentric member.

[0008] In one embodiment, clamping grooves are provided on the opposite sides of the handle.

[0009] In one embodiment, the outer wall of the sleeve has a notch communicating with the interior, the eccentric member is rotatably disposed in the notch, and the handle extends out of the sleeve through the notch.

[0010] In one embodiment, the spray assembly further includes a sealing ring, which is built into the sleeve and disposed between the fixed pipe and the nozzle.

[0011] In one embodiment, the slot is annular and arranged circumferentially along the fixed pipe.

[0012] In one embodiment, the disassembly assembly further includes a pivot pin rotatably inserted into the sleeve, an eccentric member rotatably fitted onto the pivot pin, and the axis of rotation of the eccentric member being offset from the axis of the eccentric member.

[0013] In one embodiment, the nozzle includes a connecting portion and a sealing portion. The connecting portion forms a liquid inlet cavity. One end of the liquid inlet cavity is connected to the liquid inlet channel of the fixed pipe via the sleeve, and the other end is open. The sealing portion is disposed opposite to the opening of the liquid inlet cavity and is connected to the connecting portion. A nozzle for fluid ejection is formed between the sealing portion and the connecting portion, and the nozzle is connected to the liquid inlet cavity.

[0014] In one embodiment, the nozzle is arc-shaped.

[0015] In one embodiment, there are two disassembly components, which are symmetrically arranged on both sides of the axis of the sleeve.

[0016] Compared with the prior art, the duckbill nozzle device provided by this utility model allows for easy connection between the nozzle and the fixed pipe. When the nozzle needs to be connected to the fixed pipe, the sleeve is fitted onto the fixed pipe, and then the eccentric component is rotated. The eccentric component rotates and embeds itself into the slot, abutting against the inner wall of the slot and pushing the sleeve relative to the fixed pipe, thus allowing the nozzle to fit against the fixed pipe. When the nozzle needs to be removed from the fixed pipe, the eccentric component is rotated in the opposite direction, causing it to slide out of the slot. At this point, the pushing force exerted by the eccentric component on the nozzle to fit against the fixed pipe disappears, and the sliding sleeve separates the nozzle from the fixed pipe. Separating the nozzle from the fixed pipe only requires rotating the eccentric component, making nozzle disassembly convenient. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the technical problem of inconvenient nozzle disassembly, this utility model provides a duckbill nozzle device, which can effectively solve the problem of inconvenient nozzle disassembly.

[0021] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a duckbill nozzle device in one embodiment of the present invention. The duckbill nozzle device includes a fixed pipe 1, a spraying assembly 2, and a disassembly assembly 3. The fixed pipe 1 has a liquid inlet channel 1a for fluid to pass through, and a groove 1b is formed on the outer wall of the fixed pipe 1. The spraying assembly 2 includes a sleeve 21 and a nozzle 22. The sleeve 21 is fitted onto the fixed pipe 1, and the nozzle 22 is connected to the sleeve 21. The liquid inlet end of the nozzle 22 is connected to the liquid inlet channel 1a of the fixed pipe 1 through the sleeve 21. The disassembly assembly 3 includes an eccentric member 31. The eccentric member 31 is rotatably connected to the sleeve 21 and can be rotatably embedded into and abut against the inner wall of the groove 1b. It can also push the nozzle 22 to fit against the fixed pipe 1. The eccentric member 31 can also be rotatably disengaged from the groove 1b.

[0022] When it is necessary to connect the nozzle 22 to the fixed pipe 1, the sleeve 21 is fitted onto the fixed pipe 1, and then the eccentric member 31 is rotated. The eccentric member 31 rotates and embeds into the slot 1b. The eccentric member 31 abuts against the inner wall of the slot 1b and pushes the sleeve 21 to move relative to the fixed pipe 1, so that the nozzle 22 fits against the fixed pipe 1, thus achieving the connection between the nozzle 22 and the fixed pipe 1. When it is necessary to remove the nozzle 22 from the fixed pipe 1, the eccentric member 31 is rotated in the opposite direction, so that the eccentric member 31 rotates and slides out of the slot 1b. At this time, the pushing force exerted by the eccentric member 31 on the nozzle 22 to fit against the fixed pipe 1 disappears. The sleeve 21 is slid, so that the nozzle 22 is separated from the fixed pipe 1. When separating the nozzle 22 from the fixed pipe 1, only the eccentric member 31 needs to be rotated, making the nozzle 22 easy to disassemble.

[0023] To facilitate the rotation of the eccentric member 31, in one embodiment, the disassembly assembly 3 further includes a handle 32 connected to the eccentric member 31.

[0024] In this embodiment, by setting a handle 32, which is connected to the eccentric component 31, the eccentric component 31 is rotated by the handle 32. The handle 32 extends the lever arm of the eccentric component 31 when it rotates, thereby reducing the torque required to rotate the eccentric component 31.

[0025] To facilitate the rotation of handle 32, therefore, as Figure 1 As shown, in one embodiment, clamping grooves 32a are provided on the opposite sides of the handle 32.

[0026] Clamping grooves 32a are provided on both sides of the handle 32, so that the handle 32 can be gripped through the clamping grooves 32a, making it easy to grip the handle 32.

[0027] It should be understood that the eccentric component 31 rotates under the drive of the handle 32, and the handle 32 pushes the nozzle 22 to fit against the fixed pipe 1 through the eccentric component 31. At this time, the handle 32 rotates to fit against the nozzle 22, and can be locked at the fixed pipe 1 by the cam structure of the eccentric component 31. Of course, the rotated handle 32 can also be fixed by locking screws, pins, etc.

[0028] In order to allow the handle 32 to be rotated outside the sleeve 21, for this purpose, as follows: Figure 3 and Figure 4 As shown, in one embodiment, the outer wall of the sleeve 21 has a notch 21a that communicates with the interior, the eccentric member 31 is rotatably disposed in the notch 21a, and the handle 32 extends out of the sleeve 21 through the notch 21a.

[0029] In this embodiment, the handle 32 extends into the sleeve 21 through the notch 21a. Rotating the handle 32 outside the sleeve 21 will rotate the eccentric component 31. By rotating the eccentric component 31, the connection and separation of the nozzle 22 and the fixed pipe 1 can be controlled.

[0030] To seal the connection between the nozzle 22 and the fixed pipe 1, therefore, as follows: Figure 3 As shown, in one embodiment, the spray assembly 2 further includes a sealing ring 23, which is built into the sleeve 21 and disposed between the fixed pipe 1 and the nozzle 22.

[0031] In this embodiment, when the eccentric component 31 is rotated so that the nozzle 22 is in close contact with the fixed pipe 1, the nozzle 22 and the fixed pipe 1 press against the sealing ring 23, and the sealing ring 23 can seal the gap between the nozzle 22 and the fixed pipe 1.

[0032] It should be understood that the cross-section of the sealing ring 23 can be annular, circular, square, etc., specifically, as shown in the example below. Figure 4 and Figure 5 As shown, in one embodiment, the sealing ring 23 includes two end rings 231 and two ring bodies 232. The two end rings 231 are parallel and spaced apart, and the two ring bodies 232 are disposed between the two end rings 231. The two end rings 231 are connected to the two sides of the ring body 232 respectively. The ring body 232 gradually tilts towards each other in the direction close to the center. The cross-section of the ring body 232 is ">" shaped. A through hole 23a is opened on the peripheral wall of one of the ring bodies 232 to facilitate the exhaust of gas in the sealing ring 23.

[0033] In this embodiment, when the nozzle 22 and the fixed pipe 1 approach each other, the fixed pipe 1 and the nozzle 22 clamp the sealing ring 23, causing the two end rings 231 to move towards each other. At this time, the two rings 232 approach each other and squeeze each other, and the two rings 232 deform towards each other. While deforming, they accumulate elastic restoring force, and when deforming, the two rings 232 contract towards each other, preventing the rings 232 from contracting into the liquid inlet channel 1a, and preventing the sealing ring 23 from occupying the flow area of ​​the liquid inlet channel 1a when it is squeezed and deformed.

[0034] When sleeve 21 is fitted onto fixed pipe 1, in order to ensure that eccentric member 31 can engage with slot 1b along the circumference of sleeve 21, for the following reasons: Figure 2 and Figure 3 As shown, in one embodiment, the slot 1b is annular and is arranged along the circumference of the fixed pipe 1.

[0035] In this embodiment, by setting the slot 1b to be annular, after the sleeve 21 is fitted onto the fixed pipe 1, the eccentric member 31 slides into the slot 1b. Since the slot 1b is annular, the eccentric member 31 only needs to reach the position of the annular slot 1b, and there is no need to control the circumferential position of the eccentric member 31 relative to the fixed pipe 1.

[0036] It should be understood that the eccentric component 31 and the sleeve 21 can be rotatably connected via a shaft, rotating rod, etc. Specifically, for example... Figure 1 and Figure 3 As shown, in one embodiment, the disassembly assembly 3 further includes a pivot pin 33, which is rotatably inserted into the sleeve 21. An eccentric member 31 is rotatably sleeved on the pivot pin 33, and the rotation axis of the eccentric member 31 is offset from the axis of the eccentric member 31.

[0037] By setting the pivot pin 33, the eccentric part 31 is rotatably sleeved on the pivot pin 33, realizing the rotatable connection between the eccentric part 31 and the sleeve 21. By deviating the rotation axis of the eccentric part 31 from the axis of the eccentric part 31, the eccentric part 31 can rotate into the slot 1b and rotate out of the slot 1b when rotating.

[0038] It should be understood that the nozzle 22 can be a shower head, a direct jet nozzle 22, etc., specifically, such as Figure 2 As shown, in one embodiment, the nozzle 22 includes a connecting portion 221 and a sealing portion 222. The connecting portion 221 forms a liquid inlet chamber 22a. One end of the liquid inlet chamber 22a is connected to the liquid inlet channel 1a of the fixed pipe 1 via a sleeve 21, and the other end is open. The sealing portion 222 is disposed opposite to the opening of the liquid inlet chamber 22a and is connected to the connecting portion 221. A nozzle 22b for fluid ejection is formed between the sealing portion 222 and the connecting portion 221. The nozzle 22b is connected to the liquid inlet chamber 22a.

[0039] Water flows from the inlet channel 1a through the fixed pipe 1 and into the inlet cavity 22a, and is ejected from the nozzle 22 between the sealing part 222 and the connecting part 221. When the water flows through the nozzle 22b, the flow velocity increases, forming a jet of water, which allows the water to be sprayed to a distance.

[0040] It should be understood that the nozzle 22b can be circular or elliptical, and the number of nozzles 22b can be one or more, such as... Figure 1 As shown, specifically in one embodiment, the nozzle 22b is arc-shaped.

[0041] By setting the nozzle 22b to an arc shape, when water is sprayed from the nozzle 22b, the water sprayed is in a fan shape, which can cover the area of ​​the fan shape and increase the coverage area of ​​the water spray.

[0042] It should be understood that the number of disassembled components 3 can be one, two, or more, specifically, such as Figure 1 As shown, in one embodiment, there are two disassembly components 3, which are symmetrically arranged on both sides of the axis of the sleeve 21.

[0043] In this embodiment, by providing two disassembly components 3 on both sides of the sleeve 21, and by simultaneously controlling the handles 32 in the two operating components, the connection and separation of the sleeve 21 and the fixed pipe 1 can be realized.

[0044] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
