The handle 8 is held to pull the dirt collection box 7 out of the dirt collection port 11, so that the dirt in the dirt collection box 7 can be cleaned.

Referring to fig. 1 and 4, in order to prevent the dirt collection box 7 from slipping out of the dust collection port 11, a locking assembly 10 for limiting the dirt collection box 7 is connected to a side wall of the dust collection port 11. The locking assemblies 10 are arranged in two groups and are respectively positioned on two side walls of the dust collecting opening 11 which are opposite.

Referring to fig. 4 and 5, the locking assembly 10 includes a locking lever 101 rotatably connected to a sidewall of the dust collecting port 11, and a moving groove 102 is formed in the sidewall of the dust collecting port 11 at an end of the locking lever 101, and the moving groove 102 is arc-shaped and penetrates through the sidewall of the dust collecting port 11. The end of the sliding rod 103 is fixedly provided with the sliding rod 103 which slides through the moving groove 102. The side wall of the dirt collecting box 7 is provided with a diamond-shaped groove 105 connected with the sliding rod 103 in a sliding way, and one side of the diamond-shaped groove 105 far away from the end part of the dust collecting opening 11 is recessed to a position close to the center of the diamond-shaped groove 105 to form a groove 106. An extension spring 107 is fixedly arranged at the end part of the dirt collection box 7, and the free end of the extension spring 107 is abutted against the side wall of the dust collection opening 11.

Referring to fig. 4 and 5, when the dirt collection box 7 is pushed into the dust collection port 11, the sliding rod 103 is driven to slide in the diamond-shaped groove 105 under the action of the pushing force, and when the sliding rod 103 moves to the position of the groove 106, the dirt collection box 7 can be fixed. When dirt collection box 7 is dragged out as required, earlier to the position promotion dirt collection box 7 that is close to collection dirt mouth 11 tip, because extension spring 107 pressurized produces deformation, extension spring 107 can produce the resilience force owing to recovering deformation this moment, can pop out slide bar 103 from recess 106 and make slide bar 103 slide along diamond-shaped groove 105, and the effect of reverse application power alright drag out dirt collection box 7.

Referring to fig. 4 and 5, when the dirt collection box 7 is pulled out from the dust collection opening 11, the sliding rod 103 needs to be separated from the rhombic groove 105, in order to facilitate the separation of the sliding rod 103, a sliding groove 1031 extending along the length direction of the sliding rod 103 is formed at the end of the sliding rod 103, a buffer spring 1032 is horizontally and fixedly arranged in the sliding groove 1031, a tip 1033 in sliding fit with the sliding groove 1031 is fixedly arranged at one end of the buffer spring 1032 far away from the sliding groove 1031, and one end of the tip 1033 far away from the buffer spring 1032 is hemispherical.

Referring to fig. 4 and 5, when the dirt collection box 7 is pushed into the dust collection port 11, the buffering spring 1032 pulls the head 1033 into the sliding groove 1031 under the pressing force of the mounting plate 104, so that the connection and disconnection operation between the head 1033 and the rhombic groove 105 can be easily performed.

Example 1

Referring to fig. 2 and 3, in order to prevent the washing water from flowing out along the gap between the outer bowl 31 and the outer wall of the airplane, an annular rubber strip 13 is fixedly arranged at the end of the outer bowl 31. The rubber strip 13 is made of a material with certain deformation capacity, and the outer bowl 31 can be tightly attached to the outer wall of the airplane through the deformation effect generated by the rubber strip, so that the leakage of cleaning water is prevented.

The implementation principle of the embodiment 1 is as follows: first, the spray head 3 is abutted against the outer wall of the aircraft while spraying the water in the water tank. Then, the spray head 3 is moved, sewage on the outer wall of the airplane is scraped under the action of the rubber strip 13, the power device is started, the sewage mixed with the dirt is pumped into the air pipe 5 and is discharged into the dirt collection tank 7 through the sewage discharge pipe 6 for storage. Finally, the dirt collection box 7 is pushed to a position close to the end part of the dust collection opening 11, the sliding rod 103 is ejected out of the groove 106 by the extension spring 107, the handle 8 is held to pull out the dirt collection box 7 reversely, and the sewage in the dirt collection box 7 is cleaned.

Example 2

Referring to fig. 6 and 7, the difference from embodiment 1 is that an annular mounting groove 311 is formed in a lower end surface of the outer bowl 31, and a sealing member 12 for improving the sealing property between the outer bowl 31 and the outer wall of the aircraft is connected in the mounting groove 311.

Referring to fig. 7, the sealing member 12 includes a connecting portion 121 in interference fit with the mounting groove 311 and a pressing portion 122 integrally formed with the connecting portion 121, and the connecting portion 121 is tapered and has a deformation cavity 1211 formed therein and extending into the pressing portion 122. One end of the pressing portion 122 away from the connecting portion 121 is arc-shaped.

Referring to fig. 7, the connection portion 121 is pressed, and at this time, the connection portion 121 is deformed by the deformation cavity 1211, and the connection portion 121 can be pressed into the mounting groove 311 by the tapered effect. When the nozzle 3 abuts against the outer wall of the airplane, the pressing part 122 is deformed by being pressed, so that the tightness of the connection between the two parts is improved.

Referring to fig. 7, in order to prevent cracks from being generated inside due to excessive extrusion force applied to the deformation cavity 1211 when the connection portion 121 is extruded, rounded corners 1212 are formed at four corners of the deformation cavity 1211.

Referring to fig. 6 and 7, when the nozzle 3 is moved, the arc-shaped pressing portion 122 can scrape off dirt and sewage on the outer wall of the airplane, so that the dirt suction effect is improved. In order to prevent the sealing member 12 from being removed from the mounting groove 311, the end of the connecting portion 121 far away from the mounting groove 311 is recessed toward the direction close to the center of the connecting portion 121 to form a clamping portion 123, and the notch position of the mounting groove 311 extends toward the position close to the center of the mounting groove 311 to form a flange 3111 clamped with the clamping portion 123. After the sealing member 12 is installed in the installation groove 311, the position of the sealing member 12 can be limited by the matching of the flange 3111 and the clamping portion 123, and the sealing member 12 is prevented from being separated from the installation groove 311.

The implementation principle of the aircraft decontamination device with good cleaning effect in the embodiment of the application is as follows: first, the connection portion 121 is pressed, and the seal member 12 is pressed into the mounting groove 311. Then, when the outer wall of the aircraft is scraped, the pressing portion 122 is deformed to bring the outer bowl 31 into close contact with the outer wall of the aircraft, thereby preventing the wash water from leaking out. Finally, when the sealing member 12 needs to be replaced, the connection portion 121 is pressed and removed from the mounting groove 311.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
