This utility model relates to the field of wireless earphone technology and discloses a wireless earphone with a dustproof structure, including an earphone case body and two earphone bodies. The earphone case body has two earphone slots inside, and an earphone cover is hinged to the rear upper part of the earphone case body. Two arc-shaped blocks are provided at the rear of each earphone slot, and a rotating frame is rotatably mounted in the middle of each arc-shaped block. A dustproof cover is installed on the upper end of each rotating frame, and a transparent film is provided in the middle of each dustproof cover. In this utility model, when the two dustproof covers are closed, the first sealing strip increases the sealing performance with the outer ring of the earphone slot, improving dust and water resistance, and preventing the earphone bodies from falling off and being lost. When the earphone cover is closed, the second sealing strip improves the sealing performance of the contact surface between the earphone cover and the earphone case body, preventing moisture and dust from entering the earphone case body. It also reduces noise when the earphone cover contacts the earphone case body, avoiding loud noise and not disturbing the rest of those nearby.

The application provides a child safety seat with both inclination angle adjustment and rotation control and a control method thereof. The bottom of the seat is provided with a metal frame rotatably connected to the base and an operation handle. The metal frame is provided with a gear slot. The operation handle controls the gear shaft to move in the first sliding track slot, so that the gear shaft is in the first state of being located in the gear slot and the second state of being located in the continuous slot. The base is provided with a locking slot, and the metal frame is provided with a locking block that can protrude and retract. The locking block has a control lever. The operation handle controls the control lever to move in the second sliding track slot to control the locking block to protrude or retract the metal frame. When the gear shaft is displaced along the length direction in the continuous slot, the control lever is simultaneously displaced along the length direction in the second sliding track slot. The inclination angle adjustment mechanism and the rotation control mechanism are highly integrated, and the seat body rotation control is supported under different inclination angles.
