Abstract: A device with a rotation effect includes an external barrel, a rotation barrel, a rotation mechanism, a pressing mechanism and a deceleration mechanism. The rotation barrel is disposed in the external barrel. The rotation mechanism connects with the rotation barrel for rotating the rotation barrel. The pressing mechanism connects with the external barrel. The deceleration mechanism connects with the rotation barrel to reduce the rotation speed of the rotation barrel.

Abstract: A water gun mainly comprises a water gun body which has a water channel, a nozzle, and a button for controlling water passing through the nozzle. The characteristic portion of the water gun is that the water gun further comprises an electronic device with at least one audio generator, and a water-driven generator module connected with the water channel for providing electricity for the electronic device. The electronic device provides sound or light effects to generate an entertainment effect.

Abstract: An object with a rotational effect includes an outer enclosure shell, a base, a first inner object and a rotation device. The first inner object is located inside the outer enclosure shell. A liquid is filled between the first inner object and the outer enclosure shell. The base includes a power supply to transmit electrical power to the first inner object. The first inner object comprises a first enclosure shell, at least one illumination member and a power receiving member. The power receiving member receives electrical power from the power supply, and supplies electrical power to the illumination member. The rotation device rotates the first enclosure shell.

Abstract: A computer mouse providing the functionality of a vacuum cleaner comprises a main mouse body and a vacuum device. The vacuum device is substantially mounted inside the main mouse body so that the shape of the computer mouse having the functionality of a vacuum cleaner is substantially that of the main mouse body. A user can use it as a mouse or as a vacuum cleaner to, for example, clean a computer keyboard.

Abstract: A water spray gun mainly includes a water spray gun body and an electronic device. The function of the water spray gun body just like those of prior water spray gun bodies, that is a hose is connected to the water spray gun and through which water can be sprayed. However, the shape of the water spray gun body prefers to be like a toy gun. The electronic device provides sound, or light effect to generate entertainments.

Abstract: A computer mouse with transcutaneous electro nerve stimulation capabilities includes two major devices: a computer mouse device, and a transcutaneous electro nerve stimulator (T.E.N.S.), both of which use a common casing. A first conductive region and a second conductive region are disposed on the surface of the common casing, so that the user of the computer mouse can benefit from the T.E.N.S.

Abstract: A storage device for a cleaning cloth has the shape of a computer mouse. The storage device for a cleaning cloth includes a computer mouse device, a movable shell and a storage space. The position of the storage space for the cleaning cloth is between the mouse casing and the movable shell. An open state and a closed state of the movable shell correspond to the mouse casing. When the movable shell is in the open state, a user can insert and remove the cleaning cloth.

Abstract: A combined computer mouse and speaker device includes two major devices: a mouse device and a speaker device. The speaker device may include one woofer/midrange and a pair of tweeters. Because the size of the woofer/midrange is relatively large, the woofer/midrange is preferably located at the rear portion of the combined computer mouse and speaker device. The pair of tweeters is preferably located on each side of the woofer/midrange.
