Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a hand-held vacuum cleaner that uses a battery as a power source.

BACKGROUND ART Conventionally, in a vacuum cleaner that uses a battery as a power source, as shown in FIG. , a main body 8 containing 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
It is a handle that is integrally formed on the top of the.

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 electric component 7 are arranged above the battery 5, and a handle 9 is arranged above the battery 5. .

Problems to be solved by the invention However, in such a structure, the heavy battery 5 and electric blower 4 are 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 handle 9. In addition, since the entire vacuum cleaner including the handle 9 is constructed in a straight line, when cleaning, you must hold the handle 9 with the heavy body 8 facing upwards and the suction port 1 facing downwards. This required twisting the wrist, which was tiring.

Further, as described above, since the batteries 5 and the electric blower 4 are stacked in two layers, the main body 8 is large and heavy for a handy type.

Furthermore, since it is a handy type, it may be accidentally dropped while cleaning or from a high place such as a table. etc. were often damaged and became unusable.

Also, when cleaning narrow spaces, switch to 6.
Since the switch 6 protrudes from the main body 8, there were problems such as the switch 6 hitting furniture etc. and turning off by itself.

This invention solves these problems,
The aim is to provide a rechargeable vacuum cleaner that is compact and easy to use.

Means for solving the problems In order to solve the above problems, this invention has the following features:
It consists of a battery in the rear of the roughly rectangular main body, an electric blower in the front, and a switch with a protruding knob for operation at the upper part near the bent part in the middle. In order to connect and fix the left side, one coupling boss for screw tightening is provided at the front of the switch, and another one is protruded from the surface of the main body at the bottom of the rear end of the main body on the side where the battery is placed. ing.

Function The present invention has the above-mentioned structure, which reduces the size and weight.
The main body is shaped like a rectangle, so you can clean it without twisting your wrist while holding the handle at the rear of the main body. Also, the boss for screw tightening protrudes from the main body, making it easy to clean without accidentally dropping it. Even if the switch is turned, the screw-tightening connection bosses touch together and are reinforced by the screw-tightening connection bosses, so the switch knob and the battery built-in part will not be damaged.

In addition, the screw tightening boss at the front of the switch acts as a finger stop when operating the knob, and the screw tightening boss at the lower end of the rear of the main unit acts as a rest when placing the main unit, forming a gap between it and the floor. Therefore, it can be easily lifted as it is.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings.

In FIGS. 1 and 2, reference numeral 15 indicates a filter 17 with a suction port 16 disposed at the front end to collect dust.
This is a dust collection case with a built-in dust collection case, which is detachably attached to the front part of the main body 18.

19 is an electric blower placed in the front part of the main body 18, and the electric blower chamber 2 is partitioned by a partition wall A20.
Built in 1.

A 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 rectangular shape, and the front part is partitioned off by a partition wall B24.

Reference numeral 25 denotes an electrical component compartment located in the middle between the electric blower compartment 21 and the battery compartment 23, and also arranged at a bent part of the main body 18 formed in a generally rectangular shape, and includes a switch 26, a printed circuit board 27, a 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 right main body 18a and a left main body 18b, and the right main body 18a and the left main body 18b are connected by a connecting screw 31.

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

Reference numeral 33 denotes a check valve disposed inside the dust collection case 15 so as to cover one end of the suction port 16;
This is to prevent the dirt sucked into the interior of the housing 5 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 the handle 30
When the suction port 16 is attached to the surface to be cleaned, the cut surface of the suction port 16 is fitted and the dust on the surface to be cleaned is efficiently sucked.

In addition, a suction port 16, a filter 17, an electric blower 19, an electrical component compartment 25, and a battery 22 are arranged in series, and a dust collection case 15, a main body 18, and a handle 3 are arranged in series.
0 is thin and formed into a roughly oval shape, so
The handle 30 is easy to hold and allows cleaning in a natural way.

The coupling boss 32 is connected to the knob 26 of the switch 26.
The connecting bosses 32 at the two locations protrude from the surface of the main body 18,
One coupling boss 32, knob 26 of switch 26
It protrudes from point a and is in the state of point A in FIG.
The other coupling boss 32 also connects its lower part to the dust collection case 15.
It protrudes so as to have a gap between the line connecting the lower part of the main body 18 (B in FIG. 1) and the bottom surface of the main body 18, into which the hand can be inserted.

Also, a connecting boss 32 at the lower rear end of the handle 30
is used as a rest along with the lower part of the dust collection case 15 so that it can be stably placed in the state shown in FIG.

Note that the rechargeable vacuum cleaner of the present invention is a handy type, and although it may be accidentally dropped, the coupling boss 32 prevents the knob 26a of the switch 26 from receiving any impact from falling, and is reinforced by the coupling boss 32. Therefore, not only the switch 26 but also the main body 18 will not be damaged. Similarly, the rear part of the handle 30 is also reinforced by the coupling boss 32, so that the main body in which the heavy battery 22 is housed is less likely to be damaged.

Effects of the invention As described above, according to the invention, an electric blower and a battery are arranged in series and built into the right and left sides of the main body. are combined. In addition, the two connecting bosses are placed at the front of the switch and at the bottom of the rear end of the main body, making the entire vacuum cleaner smaller and lighter, and allowing you to clean without twisting your wrist while holding the handle. .

In addition, if the switch is accidentally dropped, the main body is reinforced by the connecting boss, which protrudes from the knob and handle of the switch, so it will not be damaged. It also serves as a stopper for your fingers when operating the switch, and when cleaning a narrow space, it prevents furniture etc. from hitting the switch knob and cutting it, improving usability.

Furthermore, the connecting boss at the bottom of the rear end of the main body forms a rest together with the bottom of the dust collection case, and the handle can be easily grasped and placed as is, which significantly improves usability and makes it compact. This provides a rechargeable vacuum cleaner with excellent usability.
