Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a hand-held vacuum cleaner powered by a battery.

Conventional technology Conventionally, in vacuum cleaners that use batteries as a power source,
As shown in FIG. 6, a suction port 1 is arranged at the front, a dust collection case 3 with a built-in filter 2 is arranged, and an electric blower 4 is arranged at the rear.
The main body 8 has a built-in battery 5, a switch 6, and electrical components 7, the front dust collection case 3 is detachably attached to the main body 8, and 9 is a clap integrally formed on the upper part of the main body 8.

The main body 8 and the dust collection case 3 are arranged almost linearly, and on the main body side, a battery 5 is arranged at the bottom, an electric blower 4 and an electrical component 7 are arranged above it, and a handle 9 is arranged above it. There is.

□Problems to be solved by the invention However, in such a structure, the heavy battery 6
The electric blower 4 is located at the bottom of the main body 8, and the center of gravity of the entire vacuum cleaner is also located at the bottom of the main body 8, that is, below the handle 9. The entire vacuum cleaner including the handle 〇 is still configured in a straight line. Therefore, when cleaning, the user had to hold the handle 9 and tilt the entire vacuum cleaner diagonally so that the suction port 1 was at the bottom, which required twisting of the wrist and was tiring.

In addition, as shown in the figure, the electric blower 4 and battery 5 are arranged in two stages, upper and lower, and the main body 8 that covers them is also large, making it relatively large and heavy for a handheld type, which further impairs the usability described above. there were.

Therefore, the present invention has been developed to make the main body compact and to allow cleaning while holding the handle without twisting the wrist.The front part of the main body can be rotated to touch the cleaning surface without changing the angle at which the handle is held. Fit the suction port,
This improves usability and enables efficient cleaning.

Means to Solve the Problems In order to solve the above-mentioned problems, the present invention provides a structure in which a dust collection case with a suction port and a built-in filter is detachably attached to the front part of the main body, which has an electric blower in the front part and a built-in battery in the rear part. The main body is separated into a front body containing an electric blower and a rear body containing a battery, and the rear body is rotatably supported on the front body.

Function: The present invention has the above-described structure to reduce the size and weight of the main body, and to rotate the rear main body relative to the front main body according to the surface to be cleaned such as the floor, sofa, curtain, table, etc. This allows for easy and efficient cleaning in a natural state without twisting.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings.

In FIGS. 1 to 5, reference numeral 16 denotes a dust collection case having a suction port 16 disposed at the front end and a built-in filter 17 for collecting dust, and is detachably attached to the front part of the main body 18.

The main body 18 is composed of a front main body 19 and a rear main body 2o, the front main body 19 has an electric blower 21 built in, and the rear main body 2o has a battery 22 and a switch 23, which is a power source for the electric blower 21.
It has a built-in printed circuit board 24 and the like.

Further, the rear part of the rear main body 2o has a main body 18 and serves as a handle 26 for cleaning.

A check valve 26 is disposed inside the dust collection case 16 so as to cover one end opening of the suction port 16, and prevents the dust sucked into the dust collection case 15 from spilling out from the suction port 16.

Note that when the electric blower 21 is operated by operating the switch 23, the check valve 26 rotates inward due to its suction force.
It is designed to suck up trash.

The suction port 16 is cut diagonally and has a handle 26,
When the suction port 16 is attached to the surface to be cleaned, the cut surface of the suction port 16 fits, and dirt from the surface to be cleaned is efficiently sucked.

Reference numeral 27 denotes a rotation shaft disposed in a guide portion 28 projecting downward at the lower part of the front end of the rear body 2o, which is rotatably supported by a bearing 29 disposed at the lower part of the rear end of the front body 19.
o can be rotated.

Therefore, when cleaning by holding the handle 25, by placing the handle 26 in line with the surface to be cleaned and then rotating the main body 20, the user can hold the handle 25 in a natural manner and easily suck up the dirt from the surface to be cleaned efficiently. It is.

The suction port 16, the filter 17, the electric blower 21, the electrical components such as the switch 23, and the battery 22 are arranged in series from the front in this order, and the dust collection case 16 and main body 18 can be made thin.
It is small and lightweight, and the handle 25 makes it easy to hold.

3o is a protrusion formed on the outer periphery of the rotation shaft 27 of the rear main body 2o, 31 is a concave portion continuous to the inner periphery of the bearing 29 of the front main body 19,
The protrusion 30 engages with the recess 31 so that rotation of the rear main body 2o can be fixed at an arbitrary position.

The rotation of the rear main body 2o is within a range of approximately 180 degrees from a state in which the front main body 19 and the rear main body 2o are substantially straight to parallel as shown in FIG. etc. are also possible.

Note that even if the rotating shaft 27 of the rear body 20 and the bearing 29 of the front body 19 are reversed, the present invention still applies.

Effects of the Invention As described above, according to the present invention, the filter, electric blower, and battery are arranged in series to make the main body smaller and lighter, and the main body is divided into the front and rear parts. The flat part of the rear body can be rotated freely, and the grip part of the rear body is always held in a certain way, and the suction port is always fitted to various cleaning surfaces such as floors, sofas, curtains, and table tops, making cleaning easy and efficient. This provides a rechargeable vacuum cleaner that can.

Furthermore, when storing the main body, the main body can be placed in a straight line as shown in Fig. 1 or folded as shown in Fig. 3, and can be easily stored either by standing or hanging on a wall.
