Sex.

[0049] Referring to FIG. 1 to FIG. 10, a liquid container 10 according to an embodiment of the present invention is applied to an aircraft, and the fly is The hopper has a body 30, and the liquid container 10 is detachably coupled to the body 30. The liquid container 10 includes a container body 12 having a liquid storage chamber 120, and is disposed at the container body 12. a liquid filling port 121 and a liquid outlet 122 communicating with the liquid storage chamber 120, the liquid storage chamber 120 is for containing a liquid medicine to be sprayed; the container body 12 is inserted into the machine a lower case 124 in the body 30 and an upper case 126 supported by the body 30 and fastened to the body 30, the upper case 126 and the lower case 124 are integrally formed and shared The reservoir chamber 120 is formed.

 The liquid container 10 provided by the embodiment of the present invention is detachably coupled to the body 30, so as to quickly disassemble the liquid container 10 from the body 30, which is convenient to use. Specifically, the container body 12 of the liquid container 10 has the lower case 124 and the upper case 126 which are integrally formed, and the lower case 124 and the upper case 126 together form a container to be sprayed The liquid storage chamber 120 of the medical liquid, and having the liquid inlet 121 and the liquid outlet 122 communicating with the liquid storage chamber 120, so as to pour the liquid into the storage The liquid chamber 120 is discharged from the liquid storage chamber 120, and the liquid container 10 is mounted on the upper body of the body 30, and the lower case 124 is inserted into the machine. In the body 30, the degree of freedom of lateral movement of the liquid container 10 is restricted, and the upper case 126 is fastened to the body 30 to restrict the freedom of movement of the liquid container 10 in the vertical direction, thereby The liquid container 10 is firmly mounted on the body 30, and the upper case 126 and the body 30 are fastened to each other to ensure convenient disassembly and assembly between the two, which is beneficial to the liquid container 10. Quick disassembly and replacement.

 [0051] It should be noted that the liquid inlet 121 and the liquid outlet 122 are separately disposed on the container body 12; or, the liquid inlet 121 and the liquid outlet 122 may be The same hole is provided in the container body 12.

 Referring to FIG. 1 and FIG. 8 to FIG. 10, in the embodiment, the lower case 124 and the upper case 126 are both substantially rectangular, for example, rectangular parallelepiped. The upper case 126 and the lower case 124 are disposed in an up-and-down direction as shown in the drawing. When the liquid storage chamber 120 contains the liquid medicine to be sprayed, the lower case 124 is inserted. The upper casing 126 is placed on the fuselage 30 under the gravity of the liquid to be sprayed and is fastened to the fuselage 30 by being fastened to the fuselage 30. The liquid container 10 is prevented from swaying during flight of the aircraft, resulting in unstable flight.

[0053] In this embodiment, the aircraft can be used for agricultural products such as pesticide spraying or water sprinkling in agricultural industries. Of course, the aircraft can also be used for spraying fire extinguishing liquid in forest fires, etc. [0054] After the liquid container 10 is mounted on the upper body 30, the lower case 124 is inserted into the body 30, and the liquid container 10 is positioned to The container 10 is accurately positioned at a predetermined position on the body 30, and is fastened to the body 30 by the upper case 126 to fix the liquid container 10 to mount the liquid container 10 to The body 30 is such that the installation and disassembly of the liquid container 10 is quick and convenient, thereby improving work efficiency.

 [0055] After the single operation of the aircraft is completed, the liquid medicine cartridge needs to be replaced, the liquid container 10 can be quickly detached from the body 30, and the liquid container 10 prefilled with the liquid medicine is quickly Mounted to the fuselage 30, thereby eliminating the need for additional space for filling the liquid medicine after the aircraft is landed, and the installation and disassembly of the liquid container 10 is also convenient and quick, and the The efficiency of the aircraft.

 Referring to FIG. 1 and FIG. 8 to FIG. 10, further, the upper casing 126 is provided with a fastening structure 20 that is buckledly connected to the fuselage 30. The fastening structure 20 snaps the upper case 126 to the body 30 to conveniently fix the liquid container 10 on the body 30 such that the liquid container 10 is in the The mounting and dismounting on the body 30 is convenient and quick.

 [0057] Preferably, the fastening structure 20 may be a matching structure of the fastening component 24 and the locking groove 22, or may be a matching structure of the fastening component and the strap to limit the liquid container 10 along the The degree of freedom of movement of the body 30 is not limited to this.

 Referring to the drawings and FIG. 8 to FIG. 10, further, the cross-sectional area of the lower casing 124 in the direction of the fuselage 30 is smaller than the cross-sectional area of the upper casing 126. It can be understood that the direction of the fuselage 30 in plan view is from top to bottom in the figure, and the cross section of the lower case 124 and the upper case 126 in the direction of the body 30 is a figure. A plane formed by the front, back, and left and right directions.

[0059] In the present embodiment, the liquid container 10 is compared with the liquid container 10 having the same volume and the same height, and the unit in the lower case 124 can be reduced because the cross-sectional area of the lower case 124 is small. The amount of movement of the volume of liquid, thereby reducing the sloshing of the liquid medicine located in the lower tank 124 during flight of the aircraft Like, to ensure that the aircraft can fly smoothly. For example, the liquid medicine in the liquid container 10 may suddenly change the center of gravity of the aircraft as the flight attitude of the aircraft suddenly changes during flight, thereby causing the liquid medicine in the liquid container 10 to be caused. There is a sloshing phenomenon.

[0060] During the flight operation of the aircraft, the liquid medicine of the upper tank in the liquid container 10 flows out of the lower tank from the liquid outlet 122 under the gravity of the liquid medicine. That is, when the liquid medicine in the liquid storage chamber 120 is reduced to be located behind the lower tank 124, the flying attitude of the aircraft is significantly changed. And because the cross-sectional area of the lower case 124 along the liquid storage cavity 120 is small, the amount of movement of the liquid medicine per unit volume is reduced, and when the flight attitude of the aircraft changes, the lower case is located. The liquid medicine in 124 can reduce the sloshing phenomenon and facilitate the smooth flight of the aircraft.
