Description

Technical Field

[0001] This utility model relates to the field of dual-fluid atomizing nozzle technology, and in particular to a self-cleaning dual-fluid atomizing nozzle. Background Technology

[0002] A dual-fluid nozzle is a dust atomization tool. It mainly relies on an air compressor to provide compressed air, which is then used to atomize the liquid.

[0003] Existing technologies often employ a dual-fluid atomizing nozzle, such as the one disclosed in CN204974269U. This technology includes a locking nut, an air cap, a mixing body, an adjusting knob, an adjusting seat, and a separating core. One end of the separating core is embedded in the adjusting seat, and the other end of the separating core is equipped with an O-ring. The separating core has a core cavity inside. The end of the adjusting seat is embedded in the mixing body, and the adjusting seat and the mixing body are connected by a PTFE gasket. However, the above technologies still have problems in use due to structural limitations.

[0004] The aforementioned technology uses atomizing holes and compressed air to atomize water and perform dust suppression in industrial environments. However, this keeps the atomizing holes moist for extended periods, causing dust and impurities to adhere to and gradually clog them. The technology lacks cleaning components for the atomizing holes, making it impossible to restore their patency in a timely manner and severely impacting their normal use. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A self-cleaning dual-fluid atomizing nozzle includes a nozzle base and a flow chamber located within the nozzle base, wherein the nozzle base is provided with:

[0008] The flow chamber includes an inlet hole, an adjustment hole, an adjustment knob, and an outlet hole. The two inlet holes are respectively opened through the left and right ends of the flow chamber. The adjustment hole is opened through the upper end of the flow chamber. The adjustment knob is fitted into the adjustment hole. The outlet hole is opened through the front end of the flow chamber.

[0009] The nozzle assembly includes a nozzle element, an atomizing orifice, and a locking nut. The nozzle element is located at the discharge orifice and consists of a cylindrical shell and a hemispherical shell. The atomizing orifice is located at the hemispherical shell of the nozzle element. The locking nut is threadedly connected to the connection between the discharge orifice and the nozzle element.

[0010] The rotating plate, the spherical groove, and the cleaning protrusion are provided. The rotating plate is located at the lower end of the nozzle base, the spherical groove is located at the middle of the rotating plate, and the cleaning protrusion is integrally formed in the spherical groove.

[0011] A storage component is provided at the lower end of the nozzle base and is used to store the rotating plate that has not been cleaned.

[0012] Preferably, the discharge hole is provided with a sliding groove, and the nozzle component is integrally formed with a movable block away from the hemispherical shell, and the movable block is slidably fitted into the sliding groove.

[0013] Preferably, the storage component includes:

[0014] The nozzle includes an annular component, a connecting rod, and a guide groove. The annular component is movably fitted onto the discharge hole and abuts against the locking nut. The connecting rod is integrally formed on the annular component, and the guide groove is located at the lower end of the nozzle base.

[0015] Preferably, the storage component further includes:

[0016] The mounting plate, the movable slide, and the movable connecting plate are installed. The mounting plate is fixedly connected to the connecting rod. The movable slide is formed in the mounting plate. The movable connecting plate is slidably fitted into the movable slide.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] This invention first involves rotating the locking nut to disengage it from the nozzle component, then unscrewing the bolt between the mounting plate and the rotating plate. Next, the rotating plate is flipped so that the spherical groove is aligned with the hemispherical shell of the nozzle component, and the spherical groove is pushed towards the nozzle component, allowing the cleaning protrusion to enter the atomizing hole and push impurities in the atomizing hole into the nozzle component. Finally, the connection between the nozzle component and the discharge hole is disconnected, and the impurities in the nozzle component are poured out to restore the unobstructed state of the atomizing hole in a timely manner.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1-4 A self-cleaning dual-fluid atomizing nozzle includes a nozzle base 1 and a flow chamber located in the nozzle base 1. The nozzle base 1 is provided with an inlet hole 2, an adjustment hole 3, an adjustment knob 4, and an outlet hole 5. The two inlet holes 2 are respectively opened through the left and right ends of the flow chamber, and are used for water and compressed air to flow in respectively. The adjustment hole 3 is opened through the upper end of the flow chamber, and the adjustment knob 4 is fitted into the adjustment hole 3. The outlet hole 5 is opened through the front end of the flow chamber. The size of the chamber located at the outlet hole 5 of the flow chamber is adjusted by rotating the adjustment knob 4, thereby controlling the flow rate of water and compressed air entering the outlet hole 5.

[0029] The nozzle base 1 is also provided with a nozzle component 6, an atomizing hole 7 and a locking nut 8. The nozzle component 6 is located at the discharge hole 5 and consists of a cylindrical shell and a hemispherical shell. The atomizing hole 7 is opened at the hemispherical shell of the nozzle component 6. The locking nut 8 is threaded to the connection between the discharge hole 5 and the nozzle component 6 to lock and fix the nozzle component 6. Water and compressed air are atomized through the atomizing hole 7 and dust suppression is performed.

[0030] The nozzle base 1 is also provided with a rotating plate 9, a spherical groove 10 and a cleaning protrusion 11. The rotating plate 9 is located at the lower end of the nozzle base 1, and the spherical groove 10 is located at the middle of the rotating plate 9. When the spherical groove 10 is directly opposite the nozzle 6, since the cleaning protrusion 11 is integrally formed in the spherical groove 10, the rotating plate 9 is pushed to allow the cleaning protrusion 11 to enter the atomizing hole 7, so as to push the impurities in the atomizing hole 7 into the nozzle 6. The storage component is located at the lower end of the nozzle base 1 and is used to store the rotating plate 9 that has not been cleaned, so as to reduce the space occupied by the rotating plate 9 and facilitate the storage of the nozzle base 1.

[0031] Preferably, a sliding groove 12 is provided on the discharge hole 5, and a movable long block 13 is integrally formed on the nozzle component 6 away from the hemispherical shell. By allowing the movable long block 13 to slide and fit into the sliding groove 12, the discharge hole 5 and the nozzle component 6 are initially connected, so that the discharge hole 5 and the nozzle component 6 can be locked in the future using the locking nut 8.

[0032] The storage assembly includes an annular component 14, a connecting rod 15, and a guide groove 16. The annular component 14 is movably fitted onto the discharge hole 5. The connecting rod 15 is integrally formed onto the annular component 14. The guide groove 16 is opened at the lower end of the nozzle base 1. The connecting rod 15 is slidably fitted into the guide groove 16. When the locking nut 8 is rotated to the connection point between the nozzle component 6 and the discharge hole 5, the locking nut 8 pushes the annular component 14 against the outer wall of the nozzle base 1. At the same time, the annular component 14 drives the connecting rod 15 to move away from the nozzle component 6.

[0033] The storage components also include a mounting plate 17, a sliding groove 18, and a movable connecting plate 19. The mounting plate 17 is fixedly connected to the connecting rod 15, the sliding groove 18 is opened in the mounting plate 17, and the movable connecting plate 19 is slidably fitted into the sliding groove 18.

[0034] Preferably, the storage assembly further includes a rotating connecting rod 20 and a locking threaded hole 21. One end of the rotating connecting rod 20 is rotatably mounted on the movable connecting plate 19, and the other end of the rotating connecting rod 20 is fixedly connected to the rotating plate 9. When the connecting rod 15 moves away from the nozzle component 6, the mounting plate 17 is positioned directly below the nozzle base component 1. Then, the rotating plate 9 is flipped so that it is parallel to the mounting plate 17. The locking threaded hole 21 is opened on the mounting plate 17 and the rotating plate 9, and the mounting plate 17 and the rotating plate 9 are fixedly connected by the locking threaded hole 21 and bolts to store the rotating plate 9.

[0035] The functional principle of this utility model can be explained through the following operation methods:

[0036] When installing the nozzle component 6, first place the movable long block 13 into the sliding long groove 12 to make the nozzle component 6 initially connected with the discharge hole 5. Then, put the annular component 14 on the discharge hole 5 and abut against the outer wall of the nozzle base component 1. After that, rotate the locking nut 8 to the connection between the nozzle component 6 and the discharge hole 5 to lock the nozzle component 6.

[0037] When it is necessary to clean the atomizing hole 7, rotate the locking nut 8 to remove it from the nozzle component 6, then push the mounting plate 17 to move towards the nozzle component 6, and unscrew the bolt between the mounting plate 17 and the rotating plate 9. Then pull the movable connecting plate 19 to move towards the nozzle component 6, and then flip the rotating plate 9 so that the spherical groove 10 is aligned with the hemispherical shell of the nozzle component 6. Push the spherical groove 10 towards the nozzle component 6 so that the cleaning protrusion 11 enters the atomizing hole 7 to push the impurities in the atomizing hole 7 into the nozzle component 6. Finally, disconnect the connection between the nozzle component 6 and the discharge hole 5, and pour out the impurities in the nozzle component 6.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
