When the car was driven in succession in rainwater weather, the outside rear-view mirror lens caused the drop of water to remain easily, because travel in the rain always, and a lot of motorcycle types that do not have outside rear-view mirror heating function can't in time clear away remaining the drop of water, lead to the in-process back field of vision of traveling unclear, caused the customer to drive the potential safety hazard. Therefore, there is a need for an exterior mirror that will normally clear water droplets without the exterior mirror heating function. In view of this, the present invention provides a rearview mirror, please refer to fig. 1 to 6, which are an embodiment of the rearview mirror.

Referring to fig. 1 to 3, the rearview mirror 100 includes a housing 1 and a diversion structure 2, the housing 1 has an inner cavity 11, the housing 1 includes a first side portion 12 and a second side portion 13, the first side portion 12 is used for mounting a rearview mirror 121, the first side portion 12 and the second side portion 13 form two adjacent side walls of the inner cavity 11, and the second side portion 13 is provided with an air inlet 131; the flow guide structure 2 is detachably mounted in the inner cavity 11, the flow guide structure 2 is mounted on the inner wall of the second side portion 13 to form a flow guide groove 21 together with the second side portion 13, and an air duct 111 is formed among the flow guide groove 21, the air inlet 131 and the first side portion 12, so as to guide the air entering the inner cavity 11 from the air inlet 131 to the rearview mirror 121.

In the technical solution of the present invention, the flow guiding structure 2 is installed on the inner wall of the second side portion 13, so that when wind blows into the inner cavity 11 from the wind inlet 131, the wind can firstly enter the flow guiding groove 21, and then forms the wind channel 111 according to the flow guiding effect of the flow guiding groove 21, and blows the wind channel onto the first side portion 12, thereby blowing water drops on the rearview mirror 121 installed on the first side portion 12. The first side portion 12 and the second side portion 13 are two adjacent side portions of the housing 1, and are arranged in such a way, the length of the air duct 111 can be reduced, so that air cannot form turbulent flow in the inner cavity 11 after entering, and sufficient wind power can be achieved when the rearview mirror 121 has more water drops or other impurities. The rearview mirror 100 provided by the invention can remove water drops on the lens of the external rearview mirror 100 on the basis of not using hot drying, can be realized by utilizing wind power when an automobile runs without additionally arranging a hot drying circuit or adding a hot drying element, has a simple structure, and can save the manufacturing cost and the consumption cost of the automobile.

Referring to fig. 1, in the present embodiment, the second side portion 13 is a side portion of the housing 1 located above, the air inlet 131 is formed at a connection position of the second side portion 13 close to the first side portion 12, and the diversion structure 2 is installed on an inner wall of the second side portion 13 and extends toward the first side portion 12 to form the diversion trench 21. The second side portion 13 is above the housing 1, so that the air can be blown into the housing 1 from the air inlet 131 more smoothly when the automobile is running.
