Abstract: Present invention teaches a bamboo fabric shade that is woven in a weft and warp fashion from a plurality of bamboo filaments. An alternative embodiment of dual bamboo filaments as a single unit for the weaving is done in a similar fashion. Each bamboo filament has a high molecular mass bamboo thread inside a layer of coating wherein the coating is made to be thicker at a middle node section with the thickness tapering off towards the two distal ends of the high molecular mass bamboo thread. The coating uses PVC material, with optional addition of UV-absorbent materials. Such construction of the bamboo fabric adds to the reduction of light pollution when used for home decoration purposes.

Abstract: The present disclosure provides a vacuum cleaner main unit which is firstly provided with a mounting seat, a battery, a motor, and a dust cup. The battery, the motor, and the dust cup are all mounted on the mounting seat; the mounting seat is provided with a handle and an air inlet pipe; the air inlet pipe is fixedly connected to the handle; the motor is detachably mounted on the mounting seat; the position of the motor corresponds to the position of the handle; the battery is detachably mounted on a first end part of the motor; the dust cup is detachably mounted on a second end part of the motor; and the position of the dust cup corresponds to the position of the air inlet pipe. Compared to the existing art, the present disclosure has the advantages that the suction loss of a vacuum cleaner is reduced, and the suction power is increased, so that the weight of the vacuum cleaner is distributed more uniformly, and it is more labor-saving when the vacuum cleaner is held in a hand to do cleaning.
