Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, and in particular to a dynamic adjustment mechanism for the orifice diameter of an additive nozzle. Background Technology

[0002] Additive dynamic nozzles are a special type of nozzle that combines dynamic atomization technology with additive application, primarily used to improve atomization effects and the injection performance of functional liquids (such as fuel additives, urea solutions, etc.). Their core features include...

[0003] For example, Chinese Patent Publication No. (CN220836138U) discloses an anti-clogging nozzle, which describes: "It includes a housing, a spray nozzle, and several water guide grooves; the spray nozzle and all the water guide grooves are located at the same end of the housing; the spray nozzle is connected to the cavity of the housing; any water guide groove is recessed from the surface of the housing; any water guide groove includes a first end and a second end along its length, the first end is connected to the spray nozzle and the second end is away from the spray nozzle, and the groove depth of any water guide groove decreases from the first end to the second end; all the water guide grooves surround the periphery of the outer end of the spray nozzle. The anti-clogging nozzle provided in this application has water guide grooves around the spray nozzle, which can guide the liquid in the spray nozzle to be sprayed along part of the surface of the housing towards the periphery of the spray nozzle, which can prevent the spray nozzle from clogging and remove the adhesive around the spray nozzle, thus avoiding the adhesion and scaling of high-salt and high-impurity media at the outlet."

[0004] In summary, the nozzle also has the following technical problems: the nozzle avoids clogging by setting a guide groove, but most of the additives are liquids, and some of the additive liquids contain certain solid particles. Most nozzles can only spray liquids, and solids often accumulate and clog when passing through. Therefore, it is necessary to propose a dynamic adjustment mechanism for the nozzle orifice diameter of the additives to provide a new technical solution to solve the technical problems mentioned in the above patent. Utility Model Content

[0005] Therefore, it is necessary to provide an additive nozzle orifice dynamic adjustment mechanism to address the above-mentioned technical problems. By setting a nozzle dynamic adjustment structure in conjunction with an anti-clogging vibration structure, when the nozzle outlet is blocked, the water pressure inside the water supply pipe increases, which in turn pushes the spring push ring to descend. The liquid is discharged from the inside of the spray pipe, which pushes the push plate to drive the hammer to rotate and strike the ratchet, thereby generating vibration. This allows the object blocking the nozzle to be discharged from the nozzle outlet, thus effectively avoiding the problem of solid particles clogging the nozzle.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0011] In a preferred embodiment of the additive nozzle aperture dynamic adjustment mechanism provided by this utility model, a ratchet is fixedly connected to the surface of the nozzle, the ratchet retracts into the interior of the water supply pipe, and the bottom end of the ratchet is conical.

[0012] As a preferred embodiment of the additive nozzle aperture dynamic adjustment mechanism provided by this utility model, a protective cover is fixedly connected to the surface of the water supply pipe, and two bearings are symmetrically fixedly connected to the surface of the water supply pipe. The two bearings are located inside the protective cover, and a push plate is fixedly connected to the outer surface of the bearings in a ring array. A spray pipe is fixedly connected to the surface of the water supply pipe in a ring array, and the spray pipe is located in the middle of the spring positioning ring and the spring pushing ring.

[0014] In a preferred embodiment of the additive nozzle aperture dynamic adjustment mechanism provided by this utility model, the hammer is in close contact with the surface of the nozzle, and the nozzle is in close contact with the surface of the ratchet after it descends.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The additive nozzle aperture dynamic adjustment mechanism provided by this utility model, by setting a nozzle dynamic adjustment structure in conjunction with an anti-clogging vibration structure, when the nozzle outlet is blocked, the water pressure inside the water supply pipe increases, which in turn pushes the spring push ring to descend, and the liquid is discharged from the inside of the water spray pipe, which pushes the push plate to drive the hammer to rotate and knock the ratchet to generate vibration, thereby causing the object blocking the nozzle to be discharged from the nozzle outlet.

[0027] As described in the background art, the above-mentioned nozzles avoid clogging by setting guide grooves. However, most of the additives are liquids, and some of the additive liquids contain certain solid particles.

[0031] The additive nozzle aperture dynamic adjustment mechanism provided by this utility model, by setting a nozzle dynamic adjustment structure 2 in conjunction with an anti-clogging vibration structure 3, when the outlet of the nozzle 6 is blocked, the water pressure inside the water supply pipe 1 increases, which in turn pushes the spring push ring 7 to descend, and the liquid is discharged from the inside of the spray pipe 13, which pushes the push plate 12 to drive the hammer 17 to rotate and strike the ratchet 9 to generate vibration, thereby causing the object blocking the nozzle 6 to be discharged from the outlet of the nozzle 6. In this way, the problem of solid particles clogging the nozzle 6 can be effectively avoided.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] Please refer to Figures 1-6 An additive nozzle aperture dynamic adjustment mechanism includes a water supply pipe 1, a nozzle dynamic adjustment structure 2 is provided inside the water supply pipe 1, an anti-clogging vibration structure 3 is provided on the surface of the water supply pipe 1, and a connector 4 is fixedly connected to the top end of the water supply pipe 1.

[0034] A nozzle 6 is slidably installed inside the water supply pipe 1, and a spring positioning ring 5 is fixedly connected to the bottom end of the water supply pipe 1.

[0035] Specifically, the nozzle dynamic adjustment structure 2 includes a spring push ring 7 fixedly connected to the top of the nozzle 6, the spring push ring 7 being slidably connected to the inner wall of the water supply pipe 1, a reset spring 8 being sleeved on the surface of the nozzle 6, the reset spring 8 being located inside the water supply pipe 1, and the two ends of the reset spring 8 being fixedly connected to the spring positioning ring 5 and the spring push ring 7 respectively.

[0036] Specifically, a ratchet 9 is fixedly connected to the surface of the nozzle 6. The ratchet 9 retracts into the interior of the water supply pipe 1, and the bottom end of the ratchet 9 is conical.

[0037] Specifically, a protective cover 10 is fixedly connected to the surface of the water supply pipe 1, and two bearings 11 are symmetrically fixedly connected to the surface of the water supply pipe 1. The two bearings 11 are located inside the protective cover 10. A push plate 12 is fixedly connected to the outer surface of the bearings 11 in a ring array. A spray pipe 13 is fixedly connected to the surface of the water supply pipe 1 in a ring array. The spray pipe 13 is located in the middle of the spring positioning ring 5 and the spring pushing ring 7.

[0038] Specifically, a connecting ring 14 is fixedly connected to the bottom surface of the push plate 12, a smooth rod 15 is fixedly connected to the bottom surface of the connecting ring 14, a swing arm 16 is rotatably connected to the end of the smooth rod 15 away from the connecting ring 14, a hammer 17 is fixedly connected to the end of the swing arm 16 away from the smooth rod 15, a fixing ring 18 is fixedly connected to the surface of the smooth rod 15, and a torsion spring 19 is sleeved on the surface of the smooth rod 15.

[0039] Specifically, the hammer 17 is in close contact with the surface of the nozzle 6, and the nozzle 6 is in close contact with the surface of the ratchet 9 after it descends.

[0040] With the above structural design, when the device is in use, the connector 4 is connected to the liquid inlet pipe, and the liquid is discharged from the nozzle 6. If the nozzle 6 becomes blocked, the pressure inside the water supply pipe 1 increases. The increased pressure inside the water supply pipe 1 pushes the spring push ring 7 to squeeze the return spring 8, and the nozzle 6 slides downward to discharge the liquid from the spray pipe 13. As the nozzle 6 descends, it drives the ratchet 9 to extend out from inside the water supply pipe 1. As the liquid sprays out of the spray pipe 13, it pushes the push plate 12 to drive the bearing 11 to rotate. As the bearing 11 rotates, it drives the bottom connecting ring 14 to rotate. As the connecting ring 14 rotates, it drives the polished rod. 15 and swing arm 16 grab together. As ratchet 9 descends, its bottom is conical, and the hammer 17 is in close contact with the surface of ratchet 9. The connecting ring 14, together with the light rod 15 and swing arm 16, drives the hammer 17 to rotate and strike the surface of ratchet 9. The vibration generated by the strike is transmitted to the nozzle 6, which can then discharge the particles that are blocked inside the nozzle 6 through vibration. After the nozzle 6 is cleared, the pressure inside the water supply pipe 1 decreases. At this time, the return spring 8 pushes the spring push ring 7 to drive the nozzle 6 to slide into the water supply pipe 1, and the liquid is discharged normally from the nozzle 6. The water spray pipe 13 is in a closed state.
