Abstract: A vacuum cleaner system for the motor vehicle is provided, which comprises a negative pressure generator adapted to be connected with a motive power output of the motor to create a suction source and a dust collection chamber having a dust collection hose and in fluid communication with the negative pressure generator to enable the selective collection of dust in the dust collection chamber or the evacuation of water and other fluid. The invention incorporates a suction impeller and ratio gears, which are adapted to be coupled to the engine of the motor vehicle thus providing sustainable power and energy to the vacuuming cleaning tasks.

Abstract: A telescopic dust collecting pipe includes an outer pipe, an inner pipe inserted in the outer pipe, and a locking mechanism used for locking the relative position of the outer and inner pipe. The inner pipe and the controlling rod form an outer layer oriented groove and an inner layer oriented groove. Relative movement of the controlling rod and inner pipe brings the outer layer oriented groove to coincide or stagger with the inner layer oriented groove. A locking element moved along the radial direction is arranged between the outer pipe and inner pipe. The locking element is pressed against one side of the inner pipe by an elastic element. The relative movement between the controlling rod and inner pipe can cause the double layer oriented grooves to be coincided or staggered, so as to press or to push the locking element into or out of the oriented groove, so that the outer pipe and inner pipe are locked or released.

Abstract: A telescopic dust collecting pipe for a vacuum cleaner having an outer pipe and an inner pipe slidingly arranged therein and connected to the outer pipe by a locking device. The locking device includes an oriented locking mechanism and a locking element. The locking device fits within oriented grooves in the oriented locking mechanism to lock the inner and outer pipes relative to one another.

Abstract: A telescopic dust collecting pipe for vacuum cleaner comprises of outer pipe, inner pipe arranged slidingly in the outer pipe, said outer pipe is connected with the inner pipe by locking device; said locking device comprises of locking oriented mechanism and locking element, the characteristic is in that locking oriented mechanism comprises of fixed element fixed relatively to the inner pipe and moving element moved axially relative to the fixed element; the oriented grooves are arranged axially at least on the same sides of fixed element and moving element correspondingly to form inner and outer double layer oriented groove structures, said moving element is connected with operating device, and the operating device brings moving element to move axially to coincide or stagger inner layer oriented groove with outer layer oriented grooves; said locking element is pressed against oriented groove from side face by an elastic element, when inner layer oriented groove is coincided with outer layer oriented groove,
