The plastic member passes through the shaft mounting hole and is in contact with the middle section.

Abstract: A fanless negative ionic wind aroma diffuser includes a housing, a control circuit board, an essential oil container, a heating member, and a negative ion generation module. The control circuit board, the essential oil container, the heating member, and the negative ion generation module are mounted in an accommodation space inside the housing. The control circuit board is electrically connected with an external power source for supplying the required power to the heating member and the negative ion generation module. When actuated, the negative ion generation module generates a negative ionic wind for blowing out fragrant particles produced by heating an essential oil in the essential oil container to be quickly diffused around the surrounding, without a fan. In addition, negative ions are beneficial to health.

Abstract: A split type LED lamp includes a base and a lamp body. The lamp body has an LED light board, a second plug portion, a battery slot and a battery, and the LED light board has a plurality of LED light sources and a wireless signal receiver.
