Description

Technical Field

[0001] This utility model relates to the field of spray gun technology, specifically to a reflective rotating spray gun atomizing nozzle structure. Background Technology

[0002] Spray guns are a common piece of equipment in agricultural irrigation. For example, the utility model patent CN215784190U (the applicant's prior patent) discloses a novel uniform-speed automatic rotating spray gun, mainly comprising a rotating base, a pipe body, a steering spray pipe, a suspension bracket, a horizontal groove, a steering wheel, and a transmission mechanism. In use, the rotating base is connected to a high-pressure water jet, and the steering wheel rotates via the steering spray pipe, which in turn drives the transmission mechanism. The transmission mechanism then rotates the rotating base, directly causing the entire device to rotate. High-pressure water is sprayed from one end of the pipe body for irrigation or dust removal. While the pipe body can achieve some atomization with the help of a water atomizer while spraying water, the water mist effect is still limited and cannot meet the needs of various scenarios. Utility Model Content

[0003] The purpose of this invention is to provide a reflective rotating spray gun atomizing nozzle structure to improve the spray gun nozzle's performance and make it suitable for various scenarios.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A reflective rotary spray gun atomizing nozzle structure includes a water spray pipe, one end of which is rotatably fitted with a nozzle. The nozzle includes a housing, a main nozzle located in the central area of ​​the front part of the housing, and several secondary nozzles arranged around the main nozzle. One end of the secondary nozzle is hinged to the housing so that the angle of the secondary nozzle can be adjusted.

[0006] Furthermore, one end of the water spray pipe is rotatably assembled with the spray head via a bearing or bushing.

[0007] Furthermore, one end of the main nozzle is hinged to the housing so that the angle of the main nozzle can be adjusted.

[0008] Furthermore, one end of the main nozzle is ball-jointed to the front of the housing, the main nozzle has a first spherical connecting part, the front of the housing is provided with a first external thread section and threadedly connected to a first locking sleeve; the first external thread section has a spherical structure that cooperates with the first spherical connecting part; the first locking sleeve has a locking surface for locking the main nozzle after the angle is adjusted.

[0009] Furthermore, the housing is provided with a water cavity, and the first external thread section is formed by protruding forward from the center of the housing. The water cavity connects the water spray pipe and the main nozzle.

[0010] Furthermore, the hinge points of each of the auxiliary nozzles are evenly distributed along the circumferential direction with the first external thread segment as the center.

[0011] Furthermore, one end of the secondary nozzle is ball-jointed to the front of the housing, the secondary nozzle has a second spherical connecting part, the front of the housing is provided with a second external thread section and threadedly connected to a second locking sleeve; the second external thread section has a spherical structure that cooperates with the second spherical connecting part; the second locking sleeve has a locking surface for locking the secondary nozzle after the angle is adjusted.

[0012] Furthermore, the housing is provided with a water cavity, and each second external thread section is a hollow structure that allows the auxiliary nozzle to communicate with the water cavity.

[0013] Furthermore, both the main nozzle and the auxiliary nozzle are equipped with a water breaker, which includes a screw. Both the main nozzle and the auxiliary nozzle are equipped with a mounting part, and the screw is threadedly connected to the mounting part. When the screw extends, it can be positioned on the water spray path of the corresponding nozzle.

[0014] Furthermore, a spring is fitted onto the screw, with both ends of the spring abutting between the mounting portion and one end of the screw.

[0015] The beneficial effects of this utility model are:

[0016] (1) The reflective rotary spray gun atomizing nozzle structure of this utility model is designed with a main nozzle and a secondary nozzle, and the angle of the secondary nozzle is adjustable. It has multiple nozzles for water spraying, and can adjust the spray angle and coverage area to suit different scenarios. By adjusting the spray direction of each secondary nozzle to tilt it, the shell will rotate under the reaction force of the water flow sprayed from the secondary nozzle, and the entire nozzle will rotate around the spray pipe, achieving the purpose of spraying water and rotating at the same time, improving the atomization effect, and providing a new way of use, enriching the application scenarios.

[0017] (2) Furthermore, the main nozzle is assembled via a ball joint, which allows for angle adjustment, enabling the spray gun to have a wider spray coverage area.

[0018] (3) Both the main nozzle and the auxiliary nozzle are equipped with water shredders. When it is necessary to improve the atomization effect, the water shredders are extended to the front of the nozzle to disperse and atomize the water flow sprayed from the nozzle. When not needed, the water shredders are removed. At this time, the nozzle can achieve direct spraying and the spraying distance is longer.

[0019] Adding a spring to the water shredder can provide tension, making it less likely to fall off. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art are within the protection scope of the present utility model.

[0030] Embodiments of this utility model:

[0031] like Figures 1-5 As shown, a reflective rotating spray gun atomizing nozzle structure includes a water spray pipe 1, with a nozzle rotatably mounted at one end of the water spray pipe 1. One end of the water spray pipe 1 is used for spraying water, and the other end is connected to a high-pressure water flow. This water spray pipe 1 corresponds to the pipe body in the spray gun involved in the patent application CN215784190U. Conventional pipe bodies have a nozzle directly connected to the water outlet end via a thread. In this utility model, the nozzle is designed to rotate relative to the water spray pipe 1, enabling simultaneous water spraying and rotation.

[0032] like Figures 1-3As shown, the nozzle includes a housing 2, a main nozzle 5 located in the central area of ​​the front part of the housing 2, and several auxiliary nozzles 3 arranged around the main nozzle 5. One end of the water spray pipe 1 is rotatably assembled to the rear part of the housing 2 of the nozzle via a bearing 7 or a bushing. In this embodiment, a bearing 7 is preferred, but in other embodiments, a wear-resistant bushing may also be used.

[0033] like Figure 3 As shown, one end of the main nozzle 5 is hinged to the housing 2 so that the angle of the main nozzle 5 can be adjusted. In this embodiment, a ball joint connection is preferably used to realize the multi-angle adjustment of the main nozzle 5.

[0034] like Figure 2 As shown, the housing 2 has a water cavity 20, and the rear of the housing 2 has a mounting sleeve 22 for mating with the outer ring of the bearing 7. Figure 1 As shown, the front of the housing 2 has a first external thread section 23 and a second external thread section 21 protruding from it. Both the first external thread section 23 and the second external thread section 21 are hollow structures. The water cavity 20 connects the water spray pipe 1 with the main nozzle 5 and the auxiliary nozzle 3.

[0035] One end of the main nozzle 5 is ball-jointed to the front of the housing 2, and the hinge points of each of the auxiliary nozzles 3 are evenly distributed along the circumferential direction with the first external thread section 23 as the center.

[0036] like Figure 3 and 4 As shown, the main nozzle 5 has a first spherical connecting part 51, and the front part of the housing 2 is provided with a first external thread section 23 and a first locking sleeve 41 threadedly connected thereto. The first external thread section 23 has a spherical structure that mates with the first spherical connecting part 51, and the spherical radii of the two are matched. The first locking sleeve 41 has an internal threaded hole for threaded engagement with the first external thread section 23. In addition, the first locking sleeve 41 has a sleeve hole fitted onto the end of the main nozzle 5, and the sleeve hole has a locking surface for locking the main nozzle 5 after the angle is adjusted. The locking surface is also a spherical structure. After the angle of the main nozzle 5 is adjusted, tightening the first locking sleeve 41 will fix the position of the main nozzle 5. When long-distance water spraying is required, the main nozzle 5 can be adjusted to be perpendicular to the front part of the housing 2. At this time, the water spray hole of the main nozzle 5 and the center of the water spray pipe 1 are coaxial. Figure 3 (As shown in the diagram), this allows water in the spray pipe 1 to flow directly to the main nozzle 5 and then be sprayed out. The main nozzle 5 can also be adjusted to be tilted as needed, for example, tilted upwards or downwards to spray water.

[0037] One end of the secondary nozzle 3 is hinged to the housing 2 so that the angle of the secondary nozzle 3 can be adjusted. In this embodiment, one end of the secondary nozzle 3 is also ball-hung to the front of the housing 2, similar to the installation method of the main nozzle 5.

[0038] like Figure 3 and 5As shown, the auxiliary nozzle 3 has a second spherical connecting part 31, and the front part of the housing 2 is provided with a second external thread section 21 and threadedly connected to a second locking sleeve 42; the second external thread section 21 has a spherical structure inside, which cooperates with the second spherical connecting part 31; the second locking sleeve 42 has a locking surface inside, which is used to lock the auxiliary nozzle 3 after the angle is adjusted. The water output of the auxiliary nozzle 3 is less than that of the main nozzle 5, therefore, the inner diameter of the central hole of the second external thread section 21 is smaller than the inner diameter of the central hole of the first external thread section 23.

[0039] In this embodiment, three secondary nozzles 3 are provided. In other embodiments, the number can be adjusted as needed, such as four.

[0040] The rotation principle of the reflective rotary spray gun atomizing nozzle structure of this utility model is as follows:

[0041] like Figure 6 As shown, the portion of housing 2 where the auxiliary nozzles 3 are installed is cylindrical, and its radial line is marked as A. All three auxiliary nozzles 3 are adjusted to be tilted, forming a certain angle with the centerline of housing 2. Simultaneously, as... Figure 6 As shown in the diagram, the orientation of the secondary nozzle 3 also forms a certain angle with the radial line A. Since the water spraying direction of the secondary nozzle 3 is inclined to the radial line A, the housing 2 will rotate under the reaction force of the water flow, that is, the entire nozzle will rotate around the water spray pipe 1, achieving the purpose of spraying water while rotating, which can improve the atomization effect.

[0042] like Figure 3 As shown, both the main nozzle 5 and the auxiliary nozzle 3 are equipped with water atomizers, each including a screw 6. Both the main nozzle 5 and the auxiliary nozzle 3 have mounting parts 52 with threaded holes for the screw 6 to be installed. Since the water atomizers on the main nozzle 5 and the auxiliary nozzle 3 operate on the same principle and are installed in the same way, only one will be used as an example. Taking the auxiliary nozzle 3 as an example, the screw 6 is threadedly connected to the mounting part of the auxiliary nozzle 3. The mounting part is located on one side of the spray hole of the auxiliary nozzle 3. When the screw is extended, it is positioned in the spray path of the auxiliary nozzle 3, thus dispersing the water flow and improving the atomization effect; after the screw is retracted... Figure 3 As shown in the diagram, one end of the screw does not protrude from the mounting part to the side of the spray hole, thus not affecting the water flow from the auxiliary nozzle 3, and direct spraying can be achieved. If the nozzle angle is adjusted, the spray angle and coverage range can be changed.

[0043] like Figure 7 As shown, a spring 8 is fitted onto the screw, with its two ends abutting between the mounting part and one end of the screw. The spring 8 is designed to prevent the screw from loosening and falling off easily. The screw can be a cylindrical head screw, preferably one with a friction texture on the outer circumference for easy hand tightening; a wing screw 9 can also be used.

[0044] A schematic diagram of the reflective rotary spray gun atomizing nozzle structure of this utility model applied to a spray gun is shown below. Figure 8 As shown, the other end of the water spray pipe 1 is connected to the rotating base 10 via a connector. A steering water spray pipe 11 is also connected to the rotating base 10. The steering water spray pipe 11 sprays water onto the impeller 12 in front, causing it to rotate under the impact of the water flow. This rotation is then driven by a transmission mechanism, causing the rotating base 10 to rotate. This hydraulically driven rotation principle is existing technology. In other embodiments, it can also be applied to scenarios where the water spray pipe does not rotate with the rotating base, i.e., the other end of the water spray pipe is connected to a fixed base, which is connected to a water supply pipe.
