Embodiment Construction

[0029] figure 1 A stick vacuum cleaner in use is shown, comprising a hand-held vacuum cleaner 3 held in the hand, an elongated hard tube 5 attached to the hand-held vacuum cleaner 3 and reaching down to the ground, and a suction tube provided at the end of the hard tube 5. Dust head 7, the dust suction head 7 is in contact with the ground (the ground itself is not clearly shown in figure 1 , although there definitely are).

[0030] refer to figure 2 , the hand-held vacuum cleaner 3 includes a motor-driven fan arranged in the motor housing 9 for sucking air through a suction nozzle 11 located at the front of the hand-held vacuum cleaner 3 . The elongated hard tube 5 is connected to the suction nozzle 11, and the dust suction head 7 is connected to the lower end of the hard tube 5 again. During use, dusty air passes through the suction port 12 ( image 3 ) suction, and delivered to the suction nozzle 11 on the hand-held vacuum cleaner 3 through the hard pipe 5.

Abstract

A vacuum cleaner of the stick-type, comprises a handheld vacuum cleaner which is attached to an elongate, rigid wand and which is fluidly connected to a cleaner head provided at the end of the wand. The cleaner head is connected to the wand via a mechanical steering couple for directionally steering the cleaner head in plane parallel contact with the floor as the wand is rotated about its axis.

Description

technical field [0001] The present invention relates to the field of vacuum cleaners, and more particularly to the general type of "stick-vac" type vacuum cleaners, including hand-held vacuum cleaners, which are attached to an elongated rigid wand and which are fluidly connected to the suction head set at the end of the hard tube. Background technique [0002] Broadly speaking, there are four types of vacuum cleaners: "upright" vacuum cleaners, "canister" vacuum cleaners (also known as "canister" vacuum cleaners), "handheld" vacuum cleaners and "stick" vacuum cleaners , the latter are commonly referred to as "vacuum stick" vacuum cleaners or simply "vacuum sticks". [0003] Upright and cylinder vacuum cleaners are well known. They tend to be mains operated and used for heavier duty cleaning applications. [0004] Handheld vacuum cleaners are smaller, very portable vacuum cleaners that are best suited for lighter-duty applications such as spot cleaning of floors and trim i...
