Abstract: A toy water ball is disclosed. The toy water ball comprises a plurality of petals and a connecting member for connecting the petals, wherein each petal comprises a body and a rim extending inwards from the circumferential edge of the body. Each rim comprises magnetic members. The toy water ball has an open state and a closed state. When the toy water ball is in its closed state, the petals together enclose a water carrying cavity. The corresponding magnetic members on the two petals attract each other so the rims tightly abut each other, creating a water-blocking seal, sealing the water carrying cavity. The rims extend into the water carrying cavity. The magnetic members enables repeated open and close of the toy water ball. The toy water ball does not need a pressurized water source to fill with water.

Abstract: A diving mask includes a mask module including a mask frame, a fixing base fixed to the mask frame and a camera support base. The camera support base is detachably mounted to the fixing base, which facilitates installation and removal of the camera. The fixing base includes a receiving space with an insertion opening, a first locking opening located at a side of the receiving space and a second locking opening located at an opposite side of the receiving space. The camera support base includes an insertion portion and an elastic portion extending from the insertion portion obliquely such that when the elastic portion passes over the insertion opening to be received in the receiving space, the elastic portion is capable of restoring to its original state to selectively engage in the first locking opening or the second locking opening, which allows the shooting direction of the camera to be adjustable.

Abstract: An earbud includes a connection member, a regulating valve, an earbud body and a bladder. The connection member includes opposite first and second ends and defines a through hole extending through the first end and the second end. The regulating valve defines a flow channel therein and incudes a connection end and a working end. The connection end is tightly connected to the connection member, and the working end defines a flat adjustment opening. The flow channel communicates with the through hole of the connection member. The earbud body is mounted around the regulating valve and connected tightly to the connection member or the regulating valve. The earbud body defines a first cavity therein, and the bladder is tightly connected to the connection member and defines a second cavity for containing fluid therein. The second cavity communicates with the through hole of the connection member.

Abstract: The disclosure relates to a diving mask, including: a mask having a breath cavity corresponding to a mouth and a nose of a user; a vent tube connected to the mask and provided with an inlet passage, the inlet passage communicating the breath cavity with external air; and an exhaust device communicating the breath cavity, the exhaust device including an exhaust fan configured to discharge air in the breath cavity into an external environment, thereby enabling the external air to flow into the breath cavity through the inlet passage.
