Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural machinery manufacturing technology, and specifically relates to a spray gun. Background Technology
[0002] With the development of technology, agricultural spray guns are also constantly improving. For example, the application of intelligent management and precision spraying technology makes agricultural production more efficient and environmentally friendly. In the future, agricultural spray guns will play an even more important role in modern agriculture, promoting the intelligent and precision development of agriculture. Currently, most spray guns on the market have a single nozzle. When spraying in a columnar motion, the sprayed area is small. When spraying in a mist, the sprayed area is larger, but the spraying distance is limited to 2-3 meters.
[0003] Therefore, to address the problem of short spray distance when spraying mist liquid with existing spray guns, a new type of spray gun is needed. Utility Model Content

[0005] This utility model is achieved through the following technical solution: it includes a multi-hole nozzle and a gun body;
[0006] The multi-hole nozzle is bowl-shaped, and multiple through holes are provided on the arc surface of the multi-hole nozzle;
[0007] The multi-hole nozzle is threadedly connected to the gun body.
[0008] To better realize this utility model, the above structure is further optimized, and the multiple through holes are arranged in a straight line along the radial direction of the arc surface of the multi-hole nozzle.
[0009] To better realize this utility model, the above structure is further optimized. The multi-hole nozzle is bowl-shaped, and multiple through holes are provided on the arc surface of the multi-hole nozzle. The multi-hole nozzle is provided with threads inside.
[0010] To better realize this utility model, further optimizations are made to the above structure. The gun body includes a rod and a handle; one end of the rod is threadedly connected to the multi-hole nozzle and the other end is threadedly connected to the handle.
[0011] To better realize this utility model, the above structure is further optimized, and the handle is a zigzag shape.
[0012] To better realize this utility model, the above structure is further optimized by providing a switch on the handle.
[0013] To better realize this utility model, further optimization is made to the above structure. The handle is provided with a channel, one end of which is threaded to the rod body and the other end is connected to the liquid inlet pipe.
[0014] Compared with the prior art, this utility model has the following advantages:
[0015] This utility model provides a spray gun, including a multi-hole nozzle and a gun body. The multi-hole nozzle includes an arc surface and a columnar body, with multiple through holes disposed on the arc surface of the multi-hole nozzle. The diameter of each through hole is between 0.8mm and 1.2mm. The multi-hole nozzle is threadedly connected to the gun body. By providing multiple through holes on the arc surface of the multi-hole nozzle and setting the diameter of the through holes between 0.8mm and 1.2mm, the spray gun can achieve a longer spraying distance. Furthermore, the columnar liquid disperses upon reaching a certain distance, and the interaction of the liquid columns sprayed from each through hole achieves an atomization effect. Therefore, this spray gun combines both range and spray area. The multiple through holes in the multi-hole nozzle eliminate the need for a water separator and inner core, simplifying the structure. The multi-hole nozzle is detachable due to the threaded connection between it and the gun body. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0024] Example 1:
[0025] A spray gun includes a multi-hole nozzle 1 and a gun body;
[0026] The aforementioned multi-hole nozzle 1 includes an arc surface and a cylindrical body, and a plurality of the aforementioned through holes 2 are provided on the arc surface of the aforementioned multi-hole nozzle 1, the diameter of the aforementioned through holes being between 0.8mm and 1.2mm;
[0027] The aforementioned multi-hole nozzle 1 is threadedly connected to the aforementioned gun body.
[0028] The aforementioned structure includes a multi-hole nozzle 1 and a gun body. The multi-hole nozzle 1 is bowl-shaped, with multiple through holes 2 disposed on its arc surface. The multi-hole nozzle 1 is threadedly connected to the gun body. The multi-hole nozzle has multiple through holes on its arc surface, with the hole diameter set between 0.8mm and 1.2mm. This allows the spray gun to reach a greater distance during spraying, and the columnar liquid disperses upon reaching a certain distance. The interaction of the liquid columns sprayed from each through hole achieves an atomization effect, thus the spray gun combines both range and spray area. Furthermore, the multiple through holes in the multi-hole nozzle eliminate the need for a water separator and inner core, simplifying the structure. The threaded connection between the multi-hole nozzle and the gun body allows the multi-hole nozzle to be detached.
[0029] Multiple through holes 2 are arranged in a straight line along the radial direction of the arc surface of the multi-hole nozzle 1. This straight-line arrangement of the through holes allows the sprayed liquid column to influence each other as it disperses at the end, thereby increasing the atomization degree. Preferably, the angle between each through hole is between 8 and 12 degrees, ensuring uniform atomization of the liquid.
[0030] The aforementioned gun body includes a rod 3 and a handle 4. One end of the rod 3 is threadedly connected to the multi-hole nozzle 1, and the other end is threadedly connected to the handle 4. That is, the rod 3 serves as a channel for liquid flow, connecting the multi-hole nozzle 1 at one end and the handle 4 at the other. By providing threads at both ends of the rod 3, as well as threads on the multi-hole nozzle 1 and the handle 4, the multi-hole nozzle 1, rod 3, and handle 4 can all be disassembled for component replacement. Preferably, the multi-hole nozzle can be replaced with a ceramic nozzle, which has a smoother internal structure, reduced resistance, and a longer spray distance.
[0031] The aforementioned handle 4 is a zigzag shape. Making handle 4 a zigzag shape makes it more comfortable to hold, allowing for extended use by the operator. The multi-hole nozzle has been replaced with a ceramic nozzle.
[0032] The aforementioned handle 4 is equipped with a switch. The switch controls the opening and closing of the spray gun.
[0033] The handle 4 has a channel inside, one end of which is threaded to the rod body, and the other end is connected to the liquid inlet pipe. That is, the channel inside the handle 4 provides a liquid inlet and a liquid outlet. Specifically, the other end of the inner core 5 of one end of the channel is connected to the rod body 3, and the other end is connected to the liquid inlet pipe, which is connected to a water tank.
[0034] Specifically, the operator uses the spray gun, presses the switch, and the liquid in the tank flows through the pipe, handle 4, and rod 3 from multiple through holes 2 arranged in a straight line on the multi-hole nozzle 1. The pressure of the liquid passing through these small-diameter through holes 2 increases, thus increasing the spray distance. Multiple liquid columns disperse at the spray tip, interacting to create atomization. Furthermore, the threaded design of the rod 3, multi-hole nozzle 1, and handle 4 facilitates easy disassembly. By adjusting the number and diameter of the nozzles, the liquid can be sprayed to a distance of 8 meters, further maximizing the spray range and creating a continuous mist. This ensures optimal spray uniformity, preventing direct spraying and reducing damage to the object being sprayed.
[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
