Description

Technical Field

[0001] This utility model relates to the field of spray equipment technology, and in particular to a nozzle structure for a spray gun. Background Technology

[0002] In agricultural plant protection, industrial spraying, and environmental sanitation, spray guns are key equipment for achieving liquid atomization spraying, and the spray pattern of their nozzles directly affects the operational results. Existing spray gun nozzles mostly use vertical or inclined nozzle settings, producing droplets in cone or fan shapes. These traditional spray patterns have significant drawbacks: in agriculture, when spraying pesticides, cone or fan-shaped sprays easily lead to uneven pesticide application to crops, with insufficient pesticide adhesion at the top and edges of plants, while the center area may suffer from excessive pesticide application, causing phytotoxicity. This not only affects pest and disease control but also increases the risk of environmental pollution. In industrial spraying scenarios, for long, flat workpieces, traditional spray patterns struggle to achieve uniform coverage, often requiring repeated spraying, which not only reduces production efficiency but also wastes paint. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a nozzle structure for a spray gun. Through optimized structural design, it improves liquid flow stability, achieves uniform spraying, and enhances the overall performance and reliability of the nozzle.

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

[0005] A nozzle structure for a spray gun includes a head cap body mounted on the spray gun. The head cap body is composed of a square base and a connecting cylinder, and the connecting cylinder is used to connect to the spray gun. The square base is provided with a boss spray seat, and the boss spray seat has a spray hole cut out in the cross section.

[0006] Preferably, the connecting cylinder is provided with a first connecting ring and a second connecting ring that can form a stable connection with the spray gun. The first connecting ring and the second connecting ring create a double stable connection structure between the connecting cylinder and the spray gun, so that the nozzle structure can be stably installed on the spray gun.

[0007] Preferably, the square base is provided with an outer groove, and the protruding spray seat is located in the outer groove. The outer groove can guide the residual liquid to drip down quickly, avoid the liquid from hanging on the outer edge of the nozzle and forming droplets, and keep the nozzle appearance clean.

[0008] Preferably, the connecting cylinder is provided with a guide end, and the guide end is provided with a buffer cavity. The presence of the buffer cavity can effectively buffer and regulate the liquid pressure.

[0009] Preferably, the buffer chamber is provided with multiple water inlet grooves at equal intervals, and the water inlet grooves can correspond to or be offset from the water outlet grooves of the atomizing core on the spray gun.

[0010] Preferably, the protruding spray seat is provided with a liquid guiding groove, which is connected to the spray hole and is used to guide the liquid to converge towards the spray hole. The liquid guiding groove serves as a dedicated liquid transmission channel connecting the buffer chamber and the spray hole, and can efficiently and stably guide the liquid after buffering and guiding treatment to the spray hole.

[0011] Preferably, the edge of the liquid guiding groove is provided with a flow guiding chute, which can make the liquid form a stronger shear force and centrifugal force at the spray hole, causing the liquid to break into finer and more uniform droplets, thereby improving the atomization degree of the spray.

[0012] Preferably, a reinforcing rib is provided between the head cap body and the connecting cylinder. The reinforcing rib significantly enhances the structural strength and rigidity between the head cap body and the connecting cylinder. During spraying operations, the nozzle needs to withstand various complex loads such as liquid pressure, vibration, and external impact. The reinforcing rib can effectively disperse and transfer these loads, ensuring the integrity and stability of the entire nozzle structure.

[0013] Preferably, the guide end is provided with a clamping protrusion that can clamp with the connecting protrusion two. The mutual cooperation between the clamping protrusion and the connecting protrusion two can clamp the mounting end of the spray gun, thereby improving the stability of their installation together.

[0014] Preferably, the square base, outer groove, protruding spray seat, connecting cylinder, connecting protruding ring one, connecting protruding ring two, guide end, reinforcing rib, and clamping protruding ring are made using an integral molding technology. The application of integral molding technology brings many significant advantages to the nozzle structure. First, it eliminates the connection gaps between components, fundamentally eliminating the potential risk of liquid leakage, improving the nozzle's sealing and waterproof performance, and enabling it to work stably in harsh environments such as high humidity and high pressure. Second, the integral molding structure enhances the structural strength and rigidity of the entire nozzle, avoiding the structural weakness caused by insufficient strength of the connection parts in traditional assembly methods, enabling the nozzle to withstand greater liquid pressure and external forces, and extending its service life.

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

[0016] This invention utilizes horizontally cut spray holes on the boss spray base to spray liquid in a horizontal rectangular shape, ensuring uniform droplet coverage and solving the problem of uneven droplet density between the center and edge areas in traditional spray patterns. The connecting and clamping rings ensure stable installation, while the outer groove guides residual liquid droplets. The water inlet groove in the buffer chamber can correspond to or be offset from the water outlet groove of the atomizing core to realize spray start and stop. The liquid guiding groove and the flow guiding sloping groove optimize liquid flow and improve atomization. The one-piece molding technology enhances structural strength and sealing performance, and extends service life. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0026] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0027] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0028] Please see Figure 1-5 A nozzle structure for a spray gun includes a head cap body 1 mounted on the spray gun. The head cap body 1 is composed of a square base 2 and a connecting cylinder 6. The connecting cylinder 6 is used to connect with the spray gun. The square base 2 is provided with a boss spray seat 4, and a spray hole 5 is transversely cut on the boss spray seat 4.

[0029] The connecting cylinder 6 is equipped with a connecting protrusion 7 and a connecting protrusion 8 that can form a stable connection with the spray gun. The connection protrusion 7 and the connecting protrusion 8 form a double stable connection structure between the connecting cylinder 6 and the spray gun, so that the nozzle structure can be stably installed on the spray gun. The square base 2 is provided with an outer groove 3, and the protruding spray seat 4 is located in the outer groove 3. The outer groove 3 can guide the residual liquid to drip quickly, avoiding the liquid from hanging on the outer edge of the nozzle and forming droplets, keeping the nozzle appearance clean. The connecting cylinder 6 is provided with a guide end 9, and the guide end 9 is provided with a buffer chamber 10. The presence of the buffer chamber 10 can effectively buffer and regulate the liquid pressure.

[0030] Multiple water inlet grooves 11 are equidistantly arranged in the buffer chamber 10. The water inlet grooves 11 can correspond to or be offset from the water outlet groove of the atomizing core on the spray gun. The entire nozzle structure can be rotated through the square base 2. When spraying is required, the square base 2 is rotated so that the water inlet grooves 11 in the buffer chamber 10 are completely aligned with the water outlet groove of the atomizing core of the spray gun. At this time, the liquid can enter the buffer chamber 10 through the water outlet groove and the water inlet groove 11, and be sprayed out in a horizontal rectangular shape from the cross-cut spray hole 5 through the liquid guide groove 12 and the flow guide inclined groove 13. When it is necessary to stop spraying, simply rotate the square base 2 again to completely offset the water inlet grooves 11 from the water outlet groove of the atomizing core. The water inlet channel is blocked, and the liquid cannot enter the nozzle, thereby realizing the spray shut-off function.

[0031] The protruding spray base 4 is provided with a liquid guiding groove 12, which is connected to the spray hole 5 and is used to guide the liquid to converge towards the spray hole 5. The liquid guiding groove 12 serves as a dedicated liquid transmission channel connecting the buffer chamber 10 and the spray hole 5, which can efficiently and stably guide the liquid after buffering and guiding treatment to the spray hole 5. The edge of the liquid guiding groove 12 is provided with a flow guiding groove 13, which can make the liquid form a stronger shear force and centrifugal force at the spray hole 5, causing the liquid to break into finer and more uniform droplets, thereby improving the atomization degree of the spray.

[0032] A reinforcing rib 14 is provided between the head cap body 1 and the connecting cylinder 6. The setting of the reinforcing rib 14 significantly enhances the structural strength and rigidity between the head cap body 1 and the connecting cylinder 6. During the spraying operation, the nozzle needs to withstand a variety of complex loads such as liquid pressure, vibration, and external impact. The reinforcing rib 14 can effectively disperse and transfer these loads, ensuring the integrity and stability of the entire nozzle structure.

[0033] The guide end 9 is provided with a clamping protrusion 15 that can clamp with the connecting protrusion 8. The mutual cooperation between the clamping protrusion 15 and the connecting protrusion 8 can clamp the installation end of the spray gun, thereby improving the stability of their installation.

[0034] The square base 2, outer groove 3, boss spray seat 4, connecting cylinder 6, connecting convex ring 1 7, connecting convex ring 2 8, guide end 9, reinforcing rib 14, and clamping convex ring 15 are all made using one-piece molding technology. The application of one-piece molding technology brings many significant advantages to the nozzle structure. First, it eliminates the connection gaps between components, fundamentally eliminating the potential risk of liquid leakage, improving the nozzle's sealing and waterproof performance, and enabling it to work stably in harsh environments such as high humidity and high pressure. Second, the one-piece molding structure enhances the structural strength and rigidity of the entire nozzle, avoiding the structural weakness caused by insufficient strength of the connection parts in traditional assembly methods, enabling the nozzle to withstand greater liquid pressure and external forces, and extending its service life.

[0035] In the actual manufacturing process, the square base 2, outer groove 3, boss spray seat 4, connecting cylinder 6, connecting convex ring 1 7, connecting convex ring 2 8, guide end 9, reinforcing rib 14, and clamping convex ring 15 are made into an integral head cap body 1 using one-piece molding technology. During assembly, the connecting cylinder 6 is connected to the spray gun through connecting convex ring 1 7 and connecting convex ring 2 8 to ensure a tight and firm connection. When the spray gun is working, the liquid flows from the spray gun into the guide end 9, then flows into the buffer chamber 10, and then flows through the liquid guide groove 12 to the spray hole 5, and is sprayed out from the horizontally cut spray hole 5. The horizontally cut spray hole 5 allows the liquid to be sprayed out in a horizontal rectangular shape. Compared with the traditional cone-shaped and fan-shaped spray, the horizontal rectangular spray pattern has a more regular coverage shape, and the distribution characteristics of the horizontal rectangular spray make the droplets more uniform in the coverage area, avoiding the problem of inconsistent droplet density in the center and edge areas under the traditional spray pattern.

[0036] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
