Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric vacuum cleaner for cleaning the inside of a home, an automobile, and the like.

BACKGROUND OF THE INVENTION Conventionally, this type of electric vacuum cleaner has had a configuration as shown in FIG. In Fig. 3, reference numeral 1 denotes a main body, and inside the main body 1 there is a power battery 2, a motor 3 driven by the power battery 2, a fan 4 directly connected to the motor 3, and a switch 6 for opening and closing an electric circuit. is provided, and has a dust case 6 that is detachably attached to the main body 1 at the tip of the main body 1,
Inside the dust case 6, there is a seal packing 8 formed integrally with the filter frame 7, a filter 9 in the shape of a droplet, a suction port 1o that sucks in dust by the rotation of the fan 4, and a backflow of the sucked dust. A check valve 11 was provided to prevent this.

Next, the operation will be explained. When the switch 6 is turned on, the motor 3 rotates using the power battery 2 as a power source, and the fan/4 directly connected to the motor 3 rotates to suck in external dust from the suction port 1o, and the backflow prevention valve 11 opens and the cylindrical dust case 6
Dust is stored between the filter 9 and the top-shaped filter 9. When disposing of the stored dust in a trash can or the like, the dust case 6 is removed from the main body 1, the filter 9 is removed, and the dust inside the dust case 6 is thrown away.

Problems to be Solved by the Invention In such a conventional structure, it was not possible to sufficiently absorb dust that had gotten into the carpet using something with long naps, such as a carpet. There was also the problem that the main body was not integrated and the number of parts increased.

The present invention solves these problems by creating an electric vacuum cleaner that can easily suck in dust even from long brushed objects such as carpets, and has a reduced number of parts by integrating the main body. This is what we provide.

Means for solving the problem In order to solve this problem, the present invention not only connects a fan directly to a fan motor driven by a power battery to collect dust, but also provides a separate brush motor at the tip of the main body. The rotary brush is rotated by the rotary brush, and this rotary brush pulls out the dust from the carpet and removes the dust from the carpet.
These mechanisms are integrated into the main body.

Function As described above, the power battery stored in the main unit rotates the dust suction fan inside the main unit and the rotating brush installed at the tip of the main unit to pull out and suck in dust from long naps such as carpets. Since the main body is integrated, the number of parts can be reduced.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2. In the figure, reference numeral 21 denotes a main body having a substantially cylindrical shape with a bottom, and inside this main body 21 are a power battery 22, a fan motor 23 driven by the power battery 22, and a fan 24 directly connected to the fan motor 23. A switch 26 that opens and closes the electric circuit and a nearly box-shaped filter 26
A filter frame 29 and a seal packing 30 are provided on the side of the suction port 2 and on the side of the dust cover 28. Two sides of the filter frame 29 are open, and the other four sides are covered with the filter 26. Further, a backflow prevention valve 31 is provided to prevent dust sucked in from the suction port 2 from flowing back. Further, a brush motor 32 driven by the power battery 22 in the main body 21 and a rotary brush rotated by the brush motor 32 were disposed at the tip of the main body 21, and a dust suction port 27 was provided at the bottom thereof.

Next, the operation will be explained. When the switch 26 is turned on, the fan 24 directly connected to the fan motor 23 is rotated by the power battery 22, and the brush motor 32 at the tip of the main body 21 is driven to rotate the rotary brush 33. The dust contained in the carpet is scraped out by the rotating brush 33, and the dust is collected in the filter 26 through the suction port 27 by the fan 24 and is effectively removed.

Effects of the Invention As described above, according to the present invention, it is possible to pull out and suck in the dust that has entered even a long brushed material such as a carpet, and also to integrate the main body, the brush motor at the tip, and the rotating brush into one piece. Since it can be attached, the number of parts can be reduced.
