Abstract: An alternating current power supply apparatus sends an alternating current power to a dimmer. The dimmer dims the alternating current power to fetch a dimmed power. The dimmer sends the dimmed power to a rectification unit. The rectification unit rectifies the dimmed power to fetch a rectified power. The rectification unit sends the rectified power to an integration sampling unit and a light emitting diode. The integration sampling unit integrates, samples and converts the rectified power to fetch an integration voltage signal. The integration sampling unit sends the integration voltage signal to a voltage-to-current control conversion unit. The voltage-to-current control conversion unit converts the integration voltage signal to fetch a driving current signal to drive the light emitting diode. The driving current signal is constant, so that the light emitting diode is not blinking.

Abstract: A buckle includes a first fastener and a second fastener. The second fastener has two hooks. The first fastener includes a socket, a locking piece disposed in the socket, and two first locking portions formed on the socket for mating with the hooks. The locking piece is slidingly connected in the socket to cooperate with the second fastener. When the first fastener is engaged with the second fastener, the locking piece enters the second fastener to restrict the movement of the second fastener, so that the second fastener cannot be released unless the locking piece is removed from the second fastener and the hooks of the second fastener are pressed. Thus, the second fastener can be released only when the locking piece is moved, thereby preventing a problem that the second fastener may be separated from the first fastener when the hooks of the second fastener are incautiously pressed. A user has to move the locking piece with one hand and presses the hooks with another hand.

Abstract: The present invention provides an air blower relating to a cleaning device. The air blower includes an elastic ball body provided with a nozzle hole and a check hole, a nozzle disposed in the nozzle hole, and a check valve disposed in the check hole. A check portion of the nozzle is disposed into the elastic ball body and is tightly connected with the edge of the nozzle hole. The check portion is provided therein with a stopping assembly for blocking or opening the nozzle hole. With the stopping assembly provided at the nozzle hole, the nozzle hole is opened when the airflow within the elastic ball body is ejected out and closed when the external air enters the elastic ball body. In this way, the external air can be prevented from entering the air blower through the nozzle efficiently.
