[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] At present, if the air conditioning air volume is large when the passenger opens the external circulation mode in the heavy rain weather, the rainwater will be sucked into the air conditioning inlet through the water channel, and then dripped into the air conditioning main box, causing the problem of water leakage at the copilot rest and water inlet of the blower. The present application provides a water blocking device which can prevent external water droplets from being sucked into the vehicle through the air conditioning box inlet, and can improve the overall waterproof performance of the vehicle. However, it should be noted that the water blocking device of the present application can be used not only in the air conditioning box of the vehicle, but also in other devices such as ventilation systems. However, for the sake of convenience, the water blocking device is described below as being applied to the air conditioning box.

The water blocking mechanism 20 includes a plurality of water blocking plates 2100, the water blocking plates 2100 are arranged inclinedly towards the inside of the shell 10 in the direction of gravity X, and at least part of the water blocking plates 2100 are arranged along the direction of gravity X.

[0026] Specifically, the water blocking device 1 can be installed at the air inlet of the air conditioner box body 2, and the air inlet 11 of the shell 10 is in communication with the air inlet of the air conditioner box body 2. After the car outer circulation mode is started, when the air blower gear is adjusted to the high gear, the air speed at the air inlet of the air conditioner box body 2 is extremely large, and in heavy rain, the water droplets splashed near the air inlet of the air conditioner box body 2 are sucked into the air inlet 11 of the shell 10 under the suction of the air flow. Since the water blocking mechanism 20 is arranged at the air inlet 11 of the shell 10, the water droplets are blocked from being sucked into the main box of the air conditioner box 100 from the air inlet 11, and the air inlet 11 of the shell 10 and the air inlet of the air conditioner box body 2 are not affected, ensuring normal use of the outer circulation mode. The plurality of water blocking plates 2100 in the water blocking mechanism 20 are inclined towards the inside of the shell 10, and at least part of the water blocking plates 2100 are arranged along the gravity direction X, that is, the water blocking plates 2100 are arranged in a labyrinth manner, so as to repeatedly block the water droplets sucked into the air inlet 11, thereby improving the waterproof performance of the air inlet in the air conditioner box 100.

[0027] Wherein, the number of water blocking plates 2100 can be two, three, four or more, which is not limited here.
