Description

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

Conventional technology Conventionally, in vacuum cleaners that use secondary batteries as a power source,
As shown in FIG. 4, a suction port 1 is arranged at the front, a dust collection case 3 containing a filter 2 is placed at the rear, and an electric blower 4.
Secondary battery 5. Each has a main body 8 with a built-in switch 6 and electrical components 7, and the front dust collection case 3 has a main body 8Vc.
It was attached removably. Reference numeral 9 denotes a handle 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 a battery 5. 4. Electric blower on top of it. Electrical parts7. Furthermore, a handle e is placed above it.

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 located at the bottom of the main body 8, that is, below the handle 9.The entire vacuum cleaner, including the handle 9, has a linear structure. Therefore, when cleaning, you have to hold the handle 9 and tilt the entire vacuum cleaner diagonally so that the suction port 1 is at the bottom.
The motion involved twisting the wrist, which was tiring.

Another problem is that the switches 6 and electrical components 7 are arranged separately, making wiring and assembly difficult.
It was time-consuming. Furthermore, the switch 6 and electrical components 7 must be isolated from the fine dust leaking from the filter 2 and the heat from the electric blower 4, but since they are arranged separately as described above, isolation is difficult and may cause malfunctions. was.

Therefore, the present invention enables cleaning while holding the handle without twisting the wrist, and improves reliability by concentrating switches and electrical components in one place and isolating them.

Means for solving the problems and technical means of the present invention for solving the above problems are as follows:
The dust collector, electric blower, electrical components, and battery are arranged in series, and the main body is formed into a substantially dogleg shape, and the electrical components including the switch are separated by partition walls.

For production The effect of this technical means is as follows.

Each part is arranged in series to form a thin main body, and the main body is formed into a substantially dogleg shape, with a handle at the rear so that it can be used in a natural position by holding the handle.

Furthermore, electrical components are disposed in a mold between the electric blower and the battery to facilitate wiring processing, and the electrical components are isolated by a partition wall, thereby improving the reliability of the electrical components.

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

In FIGS. 1 to 3, 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.

Reference numeral 19 denotes an electric blower disposed at the front of the main body 18, and is housed in an electric blower chamber 21 partitioned by a partition wall 2o.

A secondary battery 22 is a power source for the electric blower 19, and is housed in a battery chamber 23 at the rear of the main body 18, which is formed in a substantially doglegged shape, and the front part is partitioned off by a partition wall 24.

Reference numeral 26 is located in the middle between the electric blower chamber 21 and the battery chamber 23, and is an electrical component chamber located at a bent portion of the main body 18 formed in a substantially dogleg shape. Printed circuit board 27. Charging plug 28. It has built-in electrical components such as a charging indicator lamp 29.

The outer periphery of the battery chamber 23 is a handle 30, and a knob 26a of the switch 26 projects from the front part of the handle 30.

The main body 18 is composed of a main body cloth 18& and a left main body 18b, which are connected by a connecting screw 31.

Numeral 32 denotes connection bosses for tightening the connection screws 31, which are arranged at three locations.

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

Note that when the electric blower 19 is operated, the check valve 33 is rotated inward by the suction force of the electric blower 19 to suck in dust.

The suction port 16 is cut diagonally and has a handle of 3°,
When the suction port 16 is attached to the surface to be cleaned, the cut surface of the suction port 16 fits and efficiently sucks in dirt from the surface to be cleaned.

In addition, the suction port 16. Filter 17. Electric blower19.
Electrical parts room 25. The batteries 22 are arranged in series, and the dust collecting case 151 main body 18 and the handle 3° are thin and formed in a substantially dogleg shape, so the handle 30 is easy to hold and can be cleaned by holding it naturally. It has become.

The electrical component room 21 partitioned off by the partition wall 20.24 is located in the middle between the electric blower room 21 and the battery room 23, as described above, and contains the electric blower 19, the battery 22, and the switch 2.
6. Wiring to the printed circuit board 27 and the like can also be done all at once in the electrical component room 21.

Further, the electrical component chamber 21 is separated by partition walls 20 and 24, and fine dust leaking from the filter 17 and exhaust heat from the electric blower 19 are also blocked.

The electrical component room 21 has an effective component arrangement in order to house various electrical components as described above, and also has a handle 3o.
A switch 26 is also placed on the front of the machine to improve usability.

Effects of the Invention As described above, the present invention concentrates electrical components such as switches and printed circuit boards in the bent part between the electric blower chamber and the battery chamber of the main body formed in a substantially dogleg shape, and The chamber is separated by a partition wall, which makes it possible to clean without twisting the wrist while holding the handle.It also blocks out fine dust leaking from the filter and exhaust heat from the electric blower, increasing reliability. This is a significant improvement. In addition, the wiring and connection processing are also included in the product, making it easy to assemble and service.

Furthermore, the front part of the handle has an electrical parts compartment with a built-in switch, making it highly usable as the switch can also be operated on the product.
