In one embodiment, as shown in fig. 1, 2 and 5, the flashing structure 2 may comprise a rectilinear end surface formed on one side of the circle. The end surface is positioned at one side of the fresh air pipeline 1. The end face is an adaptive cut-off considering that when the rainproof structure 2 is too close to the wall body, the end face can play a role in supporting under the condition that the end face is close to the wall body, and the reliability of fixing the fresh air pipe is enhanced.

In some embodiments, the flow guiding portion 20 includes a flow guiding surface 203 connected to an outer side wall of the fresh air duct 1, an inner edge of the flow guiding surface 203 connected to the outer side wall of the fresh air duct 1 forms the first end portion 201, and an outer edge of the flow guiding surface 203 opposite to the inner edge forms the second end portion 202. So set up, when the rainwater flowed to the interior border of water conservancy diversion face 203 from the outside wall of rain-proof cap 12 is first tip 201, the rainwater can scatter to the outer border that all around spreads to water conservancy diversion face 203 gradually and be second tip 202, then by play water portion 21 discharge to avoid the rainwater to flow to around the air intake 10 directly from the outside wall of rain-proof cap 12.

And then enclose into a accommodation space to make the rainwater that flows to water conservancy diversion portion 20 along the lateral wall of new trend pipeline 1 can assemble in this accommodation space, and then make the rainwater when discharging from play water portion 21, can form bigger raindrop or assemble into a strand and discharge, avoid forming little raindrop or rain fog around air intake 10.

In the above embodiment, the height of the first water retaining portion 22 protruding from the flow guide surface 203 is not less than 5 mm, and not greater than 30 mm. And then make first manger plate portion 22 can assemble the rainwater, again can practice thrift the cost.

In some embodiments, the outlet 21 includes a nozzle 211 in communication with the second end 202 to collect rain water at the second end 202 into a bundle for drainage. Thereby avoiding the rainwater from being sucked from the air inlet 10 by the air conditioner by increasing the weight of the air conditioner.

Wherein, the water outlet portion 21 may further include a plurality of water outlets 211 communicating with the second end portion 202 and distributed circumferentially along the second end portion 202.

In the above embodiment, as shown in fig. 6, the water outlet nozzle 211 includes the water outlet passage 212 communicating with the second end portion 202. An included angle which is more than or equal to 90 degrees and less than or equal to 180 degrees is formed between the bottom surface of the water outlet channel 212 and the horizontal plane. Thus, when the rainwater is discharged along the water outlet channel 212, the gravity acceleration increases the discharging speed of the rainwater, and further increases the momentum of the rainwater, thereby preventing the rainwater from being sucked from the air inlet 10 by the air conditioner. Meanwhile, the rainwater is discharged along the direction far away from the air inlet 10, and can be prevented from being sucked from the air inlet 10 by the air conditioner.

In the above embodiment, the water outlet channel 212 includes a water inlet and a water outlet. The water inlet is arranged on the first water retaining portion 22, and the water outlet is the water outlet section 210 of the water outlet portion 21.

The rain-proof structure 2 includes a second water retaining portion 25 surrounding the edge of the first lower surface 23, and the second water retaining portion 25 is located on the first lower surface 23 and protrudes from the first lower surface 23.

When the second water retaining portion 25 is not provided, when the rainwater is discharged from the water outlet portion 21, the rainwater may not only receive the suction force of the air conditioner to the rainwater, but also receive the suction force of the rain-proof structure 2 itself to the rainwater, so that the rainwater may be attached to the first lower surface 23 and gradually move toward the direction close to the air inlet 10. By providing the second water stop portion 25, this can be avoided.

In the above embodiment, the height of the second water stop portion 25 protruding from the first lower surface 23 is not less than 2 mm, and is not greater than 30 mm. And then make second water retaining part 25 can block rainwater and be inhaled to air intake 10 along first lower surface 23 in, again can practice thrift the cost.

Example four:

the difference between the present embodiment and the first embodiment is as follows: the flow guide 20 in this embodiment is gradually inclined downward in a direction away from the air inlet 10.

The included angle B is greater than or equal to 0 ° and less than or equal to 30 °, so that the speed of guiding the rainwater flowing to the periphery of the air inlet 10 from the first end portion 201 to the second end portion 202 is increased, and the rainwater is prevented from being sucked into the air inlet 10.

In the above embodiment, the first lower surface 23 forms an angle C with the horizontal plane. The included angle C is greater than or equal to 0 ° and less than or equal to 30 ° to prevent the outer edge of the first lower surface 23 from forming the air inlet 10 of another fresh air duct 1, so that the rain-proof structure 2 loses the function of preventing rainwater from being sucked into the air inlet 10.

Example five:

the difference between the present embodiment and the first embodiment is as follows: the rain protection structure 2 in this embodiment further comprises a flow guiding rib 26.

In some embodiments, as shown in fig. 5, the diversion surface 203 is provided with a plurality of diversion ribs 26, and the diversion ribs 26 extend along the direction from the first end portion 201 to the second end portion 202, so that rainwater flowing around the wind inlet 10 can be more accurately guided from the first end portion 201 to the second end portion 202.

Example six:
