Handheld vacuum cleaner host

Abstract

The invention discloses a handheld vacuum cleaner host, which comprises a dust cup, an air duct connecting pipe, a motor and a handle, wherein one end of the air duct connecting pipe is connected to a floor brush and the other end of the air duct connecting pipe is connected to an air inlet of the dust cup, and an air outlet of the dust cup is connected to an exhaust duct of the motor; the motor is arranged on one side of the air outlet of the air duct connecting pipe; an included angle between the motor and the center line of the dust cup is 0-69 degrees; the handle is arranged on one side of the dust cup; the handle and the dust cup are detachably connected; and through suction force generated from negative pressure formed due to rotation of the motor, dust is sucked by the floor brush and enters into the dust cup along the air duct connecting pipe, the dust is separated and filtered by virtue of a cyclone in the dust cup, the dust is accumulated in the dust cup, and clean air, obtained through filtration, is discharged from the motor. According to the vacuum cleaner host disclosed by the invention, the dust cup is arranged at the upper part of the air duct connecting pipe in a transverse mode, so that the entire host is compact in structure; optimally, the included angle between the motor and the center line of the dust cup is 0-30 degrees, so that smooth operation of an air duct is guaranteed and the size of the host is diminished.

Description

technical field [0001] The invention relates to the field of vacuum cleaners, in particular to a handheld vacuum cleaner host. Background technique [0002] The vacuum cleaner is an important tool for household or public environment cleaning. The working principle of the vacuum cleaner is: after the suction head is placed on the area to be cleaned, the vacuum cleaner generates an airflow, and debris and debris are entrained in the airflow and then brought into the dust. In the dust cup, sundries and debris accumulate in the dust cup for further processing. [0003] Hand-held vacuum cleaners are a commonly used household vacuum cleaner because they are smaller in size and lighter in weight than horizontal and bucket vacuum cleaners. They can also be converted into upright vacuum cleaners when equipped with a nozzle and a floor brush, which is suitable for cleaning household hygiene. At present, common handheld vacuum cleaners include direct power supply and battery-powered v...

AI Technical Summary

Problems solved by technology

[0005] (1) The motor, air duct, dust cup, and power supply end (direct power supply or battery power supply) are indispensable components of the main unit of the vacuum cleaner. The structure with the dust cup in front, this kind of main unit has a large structure and low product compactness, and the structural length of this kind of main unit is long, the center of gravity of the product is downward, heavy, and the operation and use feeling is poor

[0006] (2) The commonly used hand-held vacuum cleaners also have problems in length adjustment. There are mainly three kinds of commonly used vacuum cleaners. One is a longer fixed-handle vacuum cleaner, which can suck to higher or farther places. In a small space, it cannot be used, which brings inconvenience to vacuuming and cleaning in a small space; the second is to use a retractable handheld vacuum cleaner. This retractable handheld vacuum cleaner solves the inconvenience of the fixed type, but most of this vacuum cleaner uses Ordinary floor brushes without motors have low dust absorption strength and cleaning efficiency; the third type is to connect the floor brushes with motors to the main unit of the vacuum cleaner, which is small in size and suitable for use in small spaces, but not suitable for smaller Use in high or far places

[0007] (3) The battery of the battery-powered handheld vacuum cleaner can be removed for easy replacement. In order to facilitate the user to disassemble the battery, the commonly used battery-powered handheld vacuum cleaner generally adopts a push-type fixing structure to fix the battery. After the user presses the button, The battery pops up, this disassembly method is convenient, but the safety is not high, and children can easily remove the battery, which brings safety hazards

[0008] (4) The existing hand-held vacuum cleaners with conductive tubes and electric floor brushes are inconvenient to pull out after the conductive tubes and electric floor brushes are connected to the host (especially after vacuuming, the dust sticks to the connection port), and it is very difficult to operate
