[0030] One end of the exhaust pipe 2 is fixedly connected to a deceleration chamber 13 , and a plurality of deceleration plates 14 are arranged in the deceleration chamber 13 .

[0031] In this embodiment, the entire air-conditioning casing 1 is installed on the top of the bus. The air-conditioning casing 1 is provided with components such as an air-conditioning unit for ensuring the operation of the air-conditioning, and air is blown into the bus through an air outlet connected to the interior of the bus. The principle of this process is the existing technology and will not be described in detail here. The lower end of the exhaust duct 2 extends into the interior of the bus, so that the air collecting hood 4 is arranged inside the bus. When the interior of the bus needs to be exhausted, the fan 3 is started, and the fan 3 sucks the air inside the bus into the exhaust duct 2. During this process, the filter 7 intercepts large impurities entering the air to prevent them from entering the exhaust duct 2 and damaging the fan 3, and also prevents the exhaust duct 2 from being blocked. The filter 7 on the outlet duct 6 can prevent impurities in the outside air from entering the exhaust duct 2. When the filter screen 7 needs to be disassembled, replaced or cleaned, the movable plate 10 is moved, and the movable plate 10 drives the insertion rod 11 to move, so that the insertion rod 11 is moved out of the installation frame 5, and the spring 12 is compressed. A handle is provided on one side of the installation frame 5. The handle is pulled to drive the installation frame 5 to move out of the installation groove 8, so that the installation frame 5 drives the filter to be disassembled, and the replaced or cleaned filter screen 7 and the installation frame 5 can be installed using the opposite operation.

[0032] More specifically, when the filter screen 7 needs to be removed, the two movable plates 10 move to release the fixing of the mounting frame 5, thereby driving the filter screen 7 to be removed. The air passing through the exhaust pipe 2 enters the deceleration chamber 13, and then the air is buffered by the deceleration plate 14 to decelerate it.

[0033] See also Figure 1-5 As an implementation method for moving the movable plate 10: a push plate 15 is fixedly disposed at the lower end of the movable plate 10, the lower end of the push plate 15 passes through the fixed chamber 9 and extends to the outside of the fixed chamber 9, and a push groove 16 matching with the push plate 15 is disposed at the lower end of the fixed chamber 9.

[0034] Specifically, the pushing plate 15 is pushed so that the pushing plate 15 moves along the pushing groove 16 , and the pushing plate 15 drives the moving plate 10 to move.

[0035] See also Figure 1-5 As an implementation method for decelerating the air in the deceleration chamber 13: a plurality of deceleration plates 14 are alternately and obliquely arranged in the deceleration chamber 13, each of the deceleration plates 14 is provided with a plurality of first through holes 17, and a plurality of second through holes 18 are respectively provided on the three side surfaces of the deceleration chamber 13, one end of the three air outlet pipes 6 extends into the air-conditioning casing and is fixedly connected to the exhaust pipe 2, and the exhaust pipe 2 is communicated with the air outlet pipe 6 through a plurality of second through holes 18.

[0036] Specifically, the air entering the deceleration chamber 13 contacts the deceleration plate 14, so that part of the air is decelerated and diverted through the first through hole 17, and the other part of the air is blocked by the deceleration plate 14 and then passes through the next deceleration plate 14. The air that has been decelerated in the deceleration chamber 13 will be decelerated again through the second through hole 18, and then enter the three air outlet pipes 6 for diversion, and then discharged from the air outlet pipes 6.

[0037] See also Figure 1-5 As an implementation method for waterproofing the air outlet pipe 6: the air outlet pipe 6 is L-shaped, and a slope 19 is provided at the lower end of each air outlet pipe 6. A plurality of water baffles 20 are alternately fixed in each air outlet pipe 6, and the water baffles 20 are obliquely arranged in the air outlet pipe 6.

[0038] Specifically, the inclined surface 19 at the lower end of the air outlet duct 6 makes the opening of the lower end of the air outlet duct 6 tilt inward, and the opening is close to the air-conditioning housing 1. On rainy days, the entry of rainwater into the air outlet duct 6 can be reduced, thereby performing the first waterproofing on the air outlet duct 6. The rainwater blown into the air outlet duct 6 by the wind will be blocked by the water baffle 20, and then flow out along the water baffle 20 and the air outlet duct 6. At the same time, the air outlet duct 6 is L-shaped, so that water accidentally entering the air outlet duct 6 will also be discharged from the air outlet duct 6.

[0039] See also Figure 1-5As an implementation method for opening the exhaust duct 2: a cover body 21 is slidably connected to the exhaust duct 2 via a track structure, an electric push rod 22 is fixedly provided in the exhaust duct 2, and a driving end of the electric push rod 22 is fixedly connected to the cover body 21.

[0040] The electric push rod 22 is started, and the electric push rod 22 drives the cover body 21 to move along the sliding connection with the exhaust pipe 2, thereby opening the exhaust pipe 2. When the exhaust pipe 2 is not needed, the opposite operation can be used to close it.

[0041] To sum up, when the overall equipment is in use:

[0042] When the interior of the bus needs to be exhausted, the entire air-conditioning housing 1 is installed on the top of the bus. The air-conditioning housing 1 is provided with air-conditioning units and other components to ensure the operation of the air-conditioning, and blows air into the bus through the air outlet connected to the interior of the bus. The principle of this process is the prior art and will not be described in detail here. The lower end of the exhaust pipe 2 extends into the interior of the bus, so that the air collecting cover 4 is arranged inside the bus. When the interior of the bus needs to be exhausted, the electric push rod 22 is started, and the electric push rod 22 drives the cover 21 to move along the sliding connection with the exhaust pipe 2, so as to open the exhaust pipe 2. The fan 3 is started, and the fan 3 sucks the air inside the bus into the exhaust pipe 2. In this process, the filter 7 intercepts large impurities in the air to prevent them from entering the exhaust pipe 2 and causing damage to the fan 3. At the same time, the exhaust pipe 2 can also be prevented from being blocked. The filter 7 on the outlet pipe 6 can prevent impurities in the outside air from entering the exhaust pipe 2. When the filter screen 7 needs to be disassembled, replaced or cleaned, the push plate 15 is pushed to make the push plate 15 move along the push groove 16, and the movable plate 10 drives the insertion rod 11 to move, so that the insertion rod 11 is moved out of the installation frame 5, and the spring 12 is compressed. A handle is provided on one side of the installation frame 5. The handle is pulled to make the installation frame 5 move out of the installation groove 8, so that the installation frame 5 drives the filter to be disassembled, and the replaced or cleaned filter screen 7 and the installation frame 5 can be installed using the opposite operation.

[0043] When the exhaust air needs to be decelerated, the air entering the deceleration chamber 13 contacts the deceleration plate 14, so that part of the air is decelerated and diverted through the first through hole 17, and the other part of the air is blocked by the deceleration plate 14 and then passes through the next deceleration plate 14. The air that has been decelerated in the deceleration chamber 13 will be decelerated again through the second through hole 18, and then enter the three air outlet pipes 6 for diversion, and then discharged from the air outlet pipes 6.

[0044] When the air outlet duct 6 needs to be waterproofed, the inclined surface 19 at the lower end of the air outlet duct 6 makes the opening of the lower end of the air outlet duct 6 tilt inward, and the opening is close to the air-conditioning housing 1. On rainy days, the entry of rainwater into the air outlet duct 6 can be reduced, thereby performing the first waterproofing of the air outlet duct 6. The rainwater blown into the air outlet duct 6 by the wind will be blocked by the water baffle 20, and then flows out along the water baffle 20 and the air outlet duct 6. At the same time, the air outlet duct 6 is L-shaped, so that water accidentally entering the air outlet duct 6 will also be discharged from the air outlet duct 6.

[0045] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
