Abstract

The invention provides a handheld cleaning apparatus, comprising an apparatus body, a suction unit arranged at the front of the apparatus body, a handle arranged at the rear of the apparatus body, a power source, a gas flow generator and a filtering device. The handle has an axis obliquely extended, and the upper end of the handle is closer to the apparatus body than its lower end; the power source is arranged above the handle and raised backward; the gas flow generator is positioned below the handle and raised backward; the filtering device is positioned at the rear of the gas flow generatorand communicated with the same, wherein on a horizon, a projection of the part between the upper and lower ends of the axis of the handle is within a projection range of the gas flow generator and thefiltering device. The handheld cleaning apparatus according to the invention has the advantages that as the handle, the power source, the gas flow generator and the filtering device have reasonably arranged position, the overall structure is compact, the size is small and carrying is facilitated; the center of mass is close to the handheld part, the ergonomic demands are met, and a user can holdthe handle comfortably to move the handheld cleaning apparatus.

Description

technical field [0001] The present invention generally relates to the field of cleaning tools, in particular to a hand-held cleaning device. Background technique [0002] Existing handheld vacuum cleaners generally comprise an elongated body with an air inlet, a suction duct and a dust collection device for separating impurities and dust from the air stream. A motor and fan assembly is located in the elongated body along with the power supply. Usually, the handle is located on the upper part of the handheld vacuum cleaner. The handle is parallel to the elongated body, the suction duct extends at an angle to the axis of the elongated body, and both the air flow generator and the power supply are located within the body below the handle. The setting of the handle of such a handheld vacuum cleaner is not ergonomic, and the user will feel uncomfortable when holding the handle to perform cleaning operations. [0003] There are also hand-held vacuum cleaners that have a cylindr...
