Description

Technical Field

[0001] The utility model relates to the field of waterproof air ducts, in particular to a novel waterproof air duct. Background Art

[0002] Nowadays, cars are well sealed. Therefore, if the internal circulation is turned on for a long time, an adult breathing in a closed space of 4 cubic meters can make the carbon dioxide concentration reach 1% in about 50 minutes. At this time, the oxygen content decreases, which makes people feel hot, tired, anxious, and uncomfortable. This will affect driving safety. Therefore, the internal and external circulation should be used in combination. Especially when the air conditioner is turned on on rainy days in summer, and the external circulation is turned on, the outside air is relatively humid and contains raindrops. If the waterproof air duct at the external circulation air inlet is not equipped with a good waterproof structure, a large amount of water droplets will enter the air conditioning system, which may cause short circuit of components and cause air conditioning failure. Utility Model Content

[0003] The utility model provides a novel waterproof air duct, which can solve the problems mentioned in the background technology.

[0004] The utility model provides a novel waterproof air duct, comprising a first shell, a second shell, an air inlet, a mounting hole, an air outlet, a first water baffle, a second water baffle, a third water baffle, a fourth water baffle, a fifth water baffle, a sixth water baffle, a seventh water baffle, an eighth water baffle, a ninth water baffle and a bottom structure; the first shell is connected to the second shell; the first shell is provided with an air outlet; the first shell is provided with a first water baffle, a second water baffle, a third water baffle, a fourth water baffle, a fifth water baffle, a sixth water baffle, a seventh water baffle, an eighth water baffle and a ninth water baffle along the length direction; the first shell is provided with a bottom structure; the second shell is provided with an air inlet.

[0005] Preferably, the bottom structure and the first water baffle, the second water baffle, the third water baffle, the fourth water baffle, the fifth water baffle, the sixth water baffle, the seventh water baffle, the eighth water baffle and the ninth water baffle are not parallel to the ground but have an inclination.

[0006] Preferably, a mounting hole for mounting is provided on the second housing.

[0007] The utility model provides a new waterproof air duct. When the air conditioner external circulation is turned on, the outside air is sucked into the return air port. When a large number of water droplets or small dust particles carried in the air are blocked by the water baffle, the water droplets will flow to the second water baffle due to gravity. The second water baffle flows to the third water baffle, and so on, flowing to the eighth water baffle, the ninth water baffle, and finally to the bottom structure. The water gathers at the bottom and flows to the outside along the air inlet, thereby playing a waterproof role. The bottom structure and the first water baffle, the second water baffle, the third water baffle, the eighth water baffle, the ninth water baffle, and finally to the bottom structure. The third water baffle, the fourth water baffle, the fifth water baffle, the sixth water baffle, the seventh water baffle, the eighth water baffle and the ninth water baffle are not parallel to the ground, but have an inclination, so the waterproof effect will be better. The internal and external circulation can be switched anytime and anywhere. Don't be restricted by the situation that you dare not turn on the external circulation on rainy days, and worry that raindrops will enter the air-conditioning system and damage components. This air duct can not only block water droplets, but also block small suspended particles in the air. It also plays a good protective role for air-conditioning components, reduces the frequent failure rate of air conditioners, and extends the service life of air conditioners.

DETAILED DESCRIPTION

[0013] like Figures 1 to 4 As shown, a specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the utility model is not limited by the specific implementation method.

[0014] A novel waterproof air duct provided by an embodiment of the utility model comprises a first shell 1, a second shell 2, an air inlet 3, a mounting hole 4, an air outlet 5, a first water baffle 6, a second water baffle 7, a third water baffle 8, a fourth water baffle 9, a fifth water baffle 10, a sixth water baffle 11, a seventh water baffle 12, an eighth water baffle 13, a ninth water baffle 14 and a bottom structure 15; the first shell 1 is connected to the second shell 2; the first shell 1 is provided with an air outlet 5; the first shell 1 is provided with a first water baffle 6, a second water baffle 7, a third water baffle 8, a fourth water baffle 9, a fifth water baffle 10, a sixth water baffle 11, a seventh water baffle 12, an eighth water baffle 13 and a ninth water baffle 14 along the length direction; the first shell 1 is provided with a bottom structure 15; the second shell 2 is provided with an air inlet 3.

[0015] In this embodiment, the bottom structure 15 and the first water baffle 6, the second water baffle 7, the third water baffle 8, the fourth water baffle 9, the fifth water baffle 10, the sixth water baffle 11, the seventh water baffle 12, the eighth water baffle 13 and the ninth water baffle 14 are not parallel to the ground, but have an inclination.

[0016] In this embodiment, a mounting hole 4 for mounting is provided on the second housing 2 .

[0017] Working principle: When the air conditioner is turned on, the outside air is sucked into the return air port. When a large amount of water droplets or small dust particles are carried in the air, they will be blocked by the water baffle. When the water droplets are blocked by the first water baffle 6, they will flow to the second water baffle 7 due to gravity. The second water baffle 7 flows to the third water baffle 8, and so on, flowing to the eighth water baffle 13, the ninth water baffle 14, and finally to the bottom structure 15. The water gathers at the bottom and flows to the outside along the air inlet 3, thereby playing a waterproof role. The bottom structure 15 and the first water baffle 6, the second water baffle 7, the third water baffle 8 The fourth water baffle 9, the fifth water baffle 10, the sixth water baffle 11, the seventh water baffle 12, the eighth water baffle 13 and the ninth water baffle 14 are not parallel to the ground, but have an inclination, so the waterproof effect will be better, and the internal and external circulation can be switched anytime and anywhere. Don't be restricted by the situation that you dare not turn on the external circulation on rainy days, worrying that raindrops will enter the air-conditioning system and damage components. This air duct can not only block water droplets, but also can well block small suspended particles in the air, and also play a good protective role on air-conditioning components, reduce the frequent failure rate of air-conditioning, and extend the service life of air-conditioning.
