Vacuum cleaner

Abstract

Disclosed is a vacuum cleaner, comprising an electric motor (1) for suctioning an air flow. The air flow flows in an air flow channel in the cleaner, and passes in sequence through the electric motor (1), an electric motor air discharge port (12) and a discharged air filter (2). An air discharging port (41), an air blowing port (44) and a conversion valve (3) are provided downstream of the discharged air filter (2). The air discharging port (41) is located beside the air blowing port (44), and the conversion valve (3) is located in the air blowing port (44) and can slide in the air blowing port (44) to open or close the air discharging port (41) and the air blowing port (44). The vacuum cleaner further makes it possible to filtrate the air flow discharged out of the cleaner, and has the function of switching between air discharging and air blowing, and has a simple structure and low cost.

Description

technical field [0001] The invention relates to a vacuum cleaner, more specifically, to a vacuum cleaner with a blowing function. Background technique [0002] General vacuum cleaners only have the ability to bring dust into the vacuum cleaner from the outside through the airflow, and through the filtration of the vacuum cleaner filter system, dust and other sundries are left in the vacuum cleaner, and the filtered airflow is discharged from the vacuum cleaner through the air duct. The vacuum cleaner with blowing function means that the airflow discharged from the vacuum cleaner can be reused, so that the airflow can be collected and blown out from the blowing port. In the existing vacuum cleaners with blowing function, one is that the air outlet is directly a circular air outlet structure that can be matched with the hose. When blowing, the hose can be directly inserted into the air outlet to achieve blowing. The airflow discharged from the air outlet is concentrated and u...

Problems solved by technology

In the existing vacuum cleaners with blowing function, one is that the air outlet is directly a circular air outlet structure that can be matched with the hose. When blowing, the hose can be directly inserted into the air outlet to achieve blowing. The airflow discharged from the air outlet is concentrated and unguided. This kind of strong airflow with the temperature of the motor is easy to cause burns or discomfort when blown on people, and it will cause secondary pollution when blown on the ground or furniture; One type of blowing function is that the blowing port has a cover. When using the blowing function, insert the hose into the blowing port. At this time, the hose will push the cover of the blowing port away. After the blowing port cover is rotated 90 degrees, it can block the normal The wind path of the air outlet, so as to realize the blowing, but this structure is not convenient to install the air outlet filter system, so it is not suitable for household, dry, mid-to-high-end vacuum cleaners; there is also a blowing function to design two air outlets for the air outlet, One is used for blowing air and the other is used for blowing. Usually, the blowing outlet is covered with a cover. When blowing, the cover is removed, and then inserted into the suction port. When blowing, the air outlet still emits air. This structure greatly affects the blowing flow, and It is necessary to manually unscrew the blower cover, which is cumbersome to operate and is not conducive to user use

In addition, the wind blown by the above three solutions is unfiltered and contains toner and other residues, causing secondary pollution and is not conducive to human health.
