[0028] The technical solution of the present invention is further specifically described below through specific embodiments in combination with the accompanying drawings; it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not intended to limit the present invention in any way; the accompanying drawings in the present invention are only used to assist in the description of the embodiments and to facilitate understanding, and are not intended to limit the present invention in any way.

[0029] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them, and are not used to limit the conditions under which the present invention can be implemented. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical contents disclosed in the present invention without affecting the effects and purposes that can be achieved by the present invention.

[0030] As described in the background technology, the existing UAV spraying device is not convenient for adjusting the drainage volume, which makes it inconvenient to adjust according to the actual situation during spraying, and it is not convenient to replace the spray head to adapt to different scenarios.

[0031] For the reasons stated above, please refer to the attached Figure 1 The utility model provides an adjustable atomizing spray head, comprising a hollow crossbeam 1, a water inlet and an air inlet are provided on the top, and a plurality of drainage pipes 2 are evenly arranged on the bottom;

[0032] The valve body 3 is arranged in the drain pipe 2 and keeps sliding to realize the opening and closing of the drain pipe 2;

[0033] A spray pipe 4 is movably mounted on the drain pipe 2 and is used to push the valve body 3 to move and open the drain pipe 2;

[0034] The spray head 7 is movably mounted on the end of the spray pipe 4 .

[0035] Specifically, one end of the valve body 3 passes through the drain pipe 2 and is inserted into the hollow beam 1, and a sealing head 5 is provided at the end of the end. An elastic member 6 is provided between the sealing head 5 and the inner wall of the hollow beam 1. The sealing head 5 is pressed against the end of the drain pipe 2 in the hollow beam 1 through the elastic member 6 to achieve the closure of the drain pipe 2.

[0036] According to the above technical features, the sealing head of the valve body can be fixed on the end of the drain pipe at the inner end of the hollow beam through the setting of the elastic part, thereby realizing the closure of the drain pipe and preventing the valve body from sliding up and down randomly due to shaking during the spraying process, causing liquid leakage.

[0037] Specifically, the valve body 3 is fitted to the inner wall of the drain pipe 2 , a drain slot is provided on the inner end of the drain pipe 2 , and an external thread is provided on the outer end of the drain pipe 2 .

[0038] According to the above technical features, the valve body and the drain pipe are arranged to fit the inner walls to ensure that the valve body does not shake when sliding up and down, thereby ensuring its stability. The drainage groove hole at the inner end of the drain pipe is arranged to facilitate the liquid at the inner end of the hollow beam to flow into the gap between the sealing head and the end of the drain pipe, and to pass through the drainage groove hole into the spray pipe at the lower end for spraying.

[0039] Specifically, one end of the spray pipe 4 is open and keeps the open end cylindrical, and the other end is conical. An internal thread matching the external thread of the drain pipe 2 is provided on the inner side of the opening of the cylindrical end of the spray pipe 4. The conical end of the spray pipe 4 keeps the small end connected to the cylindrical end, and a plurality of drainage holes 4.1 are evenly provided on the large end.

[0040] According to the above technical features, the connection method between the spray pipe and the drain pipe is convenient for connection and fixation. At the same time, the valve body can be pushed upward according to the connection method to squeeze the spring so that the sealing head at the end of the valve body is separated from the end of the drain pipe, thereby realizing the opening of the drain pipe. In addition, the gap between the sealing head and the end of the drain pipe can be adjusted at will according to the connection method, thereby realizing the adjustment of the water inlet amount, which is convenient for adjusting the water inlet amount according to different spraying needs.

[0041] Specifically, the drainage hole 4.1 is in the shape of a stepped hole, the large hole of which is arranged outside the conical end of the spray pipe 4, and an internal thread is opened on the inner wall of the large hole of the stepped hole to facilitate the movable installation of the spray head 7.

[0042] According to the above technical features, setting the drain hole as a stepped hole is convenient for installing and disassembling the sprinkler head and will not affect the spraying.

[0043] Specifically, one end of the spray head 7 is cylindrical and the other end is conical. The cylindrical end of the spray head 7 is provided with an external thread matching the internal thread of the drain hole 4.1. The spray head 7 is also provided with a center hole that is adapted to the small hole of the drain hole 4.1.

[0044] According to the above technical features, the specific shape of the sprinkler head is set to facilitate the movable connection of one end with the drain hole without affecting the spraying, thereby realizing the detachable installation of different types of sprinkler heads.

[0045] Furthermore, the sprinkler head may also be configured in other forms (such as the fan-shaped sprinkler head and porous conical sprinkler head described above). It is only necessary to ensure that the water inlet end is a cylinder with a center hole and an external thread is provided at the outer end of the cylinder to facilitate connection with the drainage hole.

[0046] For the convenience of display in the drawings, the thread line is not shown in the drawings. This is a commonly used connection method in the mechanical field and is therefore not shown in the drawings.

[0047] When the device is in use, the water inlet of the hollow beam 1 is pre-connected with the water tank on the external drone, and the air inlet on the hollow beam 1 is connected to the air pump. Then, according to the required spraying scenario and the required spraying amount, a suitable type of spray head 7 is installed, and the spray pipe 4 with the spray head 7 installed is installed on the drain pipe 2 at a suitable position until the valve body 3 is pushed up to the appropriate position to ensure that the amount of liquid sprayed by the spray pipe 4 reaches the standard of the required spraying amount. The installation method of the spray head 7 and the spray pipe 4 is threaded connection, which will not be repeated here. Finally, the external drone is started to drive the device to fly above the spraying site, and the external air pump is started to perform the spraying operation.

[0048] The above description is a detailed description of the preferred feasible embodiment of the utility model, but the embodiment is not used to limit the scope of the patent application of the utility model. All equivalent changes or modified changes completed under the technical spirit suggested by the utility model should fall within the patent scope covered by the utility model.
