Abstract

PURPOSE:To change the position of the gravity center of a vacuum cleaner to a position for attaining an easy use of it corresponding to a place where it is used, by providing a specified pipe hole at the opposite end of a suction port of a main body, a specified connector on a suction attachment, a connector on a handle, and a specified extension pipe. CONSTITUTION:When the center of gravity is shifted close to a suction attachment 2, a connector 2a of the suction attachment 2 is inserted into a suction port 1b of a main body 1, an end 4a of an extension pipe 4 is inserted into a pipe hole 1c of the main body 1, and a handle 3 is mounted on the other end 4b of the extension pipe 4. That is, the suction attachment 2 is directly attached to the main body 1 and the handle 3 is attached via the extension pipe 4, so that the center of gravity comes close to the suction attachment 2. Next, when the center of gravity is moved close to the handle 3, the end 4a of the extension pipe 4 is inserted into the suction port 1b, the other end 4a is inserted into the connector 2a of the suction attachment 2, and the connector 3a of the handle 3 is inserted into the pipe hole 1c of the main body 1. That is, the suction attachment 2 is attached to the main body 1 via the extension pipe 4, and the handle 3 is directly mounted on the main body 1, so that the center of gravity approaches the handle 3.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a vacuum cleaner.

Conventional technology Stick-type vacuum cleaners are roughly divided into two types, one shown in Figure 7 and the other shown in Figure 8. In Figure 7, 20 has a built-in electric blower. The main body 21 is a suction device for the floor, and 22 is a handle with a handle 23 at the tip.The suction device 21 is directly fitted into the air inlet of the main body, and even if the handle 22 is attached to the other end of the main body 20, the eighth In the figure, 24 is a main body with a built-in electric blower, and a handle 25 is attached to the main body 24.
is provided. 26 is a suction device, and the main body 2
A suction pipe 27 is attached to the air supply port 4, and a suction tool is attached to the tip of the suction pipe 27.

Problems to be Solved by the Invention However, the conventional configuration described above had the following problems.
The center of gravity is near the suction device and is far from the handle, making it difficult to lift it to a high place for use. In addition, in the case of the configuration shown in Fig. 8, the center of gravity is located near the handle 25, so it is easy to operate at high places, but when cleaning at low places such as the floor, most of the center of gravity is at the handle. 25, which makes it feel heavy for the user, troublesome to handle, and difficult to use.Means for solving the problem: A suction port is formed at one end of the main body, and a suction port of the same diameter as the suction port is formed at the other end. A pipe hole is formed, and the suction device is provided with a connecting part that has approximately the same diameter as the inlet of the main body, and the handle is provided with a connecting part that is approximately the same diameter as the pipe hole of the main body, and the outer diameter of one end and the inner diameter of the other end are respectively as above. By changing its position, the center of gravity can be moved to the vicinity of the suction device and the handle by attaching the extension pipe, which has an extension pipe formed almost the same as the suction port of the main body.

Embodiment FIG. 1 is an exploded perspective view of a vacuum cleaner according to an embodiment of the present invention. Reference numeral 1 denotes a main body that includes an electric blower (not shown) and a dust container 1a, and a pipe hole 1c having the same diameter as the suction port 1b is formed at the other end. Further, as shown in FIG. 5, a rib ld is formed on a part of the edge of the suction port 1b. Reference numeral 2 designates a suction device for the floor, and a connecting portion 2a is formed to have an outer diameter approximately the same shape as the suction port so that it can be inserted into the suction port 1b of the main body 1. 3 is a handle, and the outer diameter of the connecting portion 3a is almost the same shape as the pipe hole [C]. 4 is an extension pipe in which the outer diameter of one end 4a and the inner diameter of the other end 4b are approximately the same diameter as the inlet IC, and the end of the one end 4a corresponds to a rib 1d as shown in FIG. cutout 4
c is formed.

Switching of the center of gravity position of the vacuum cleaner configured as described above will be explained.

First, the case where the center of gravity is located near the suction tool will be explained with reference to FIG.

To install the suction tool 2 into the suction port 1b of the main body 1, insert the part 2a into the pipe hole IC of the main body 1 and insert one end 4 of the extension pipe 4 into the pipe hole IC of the main body 1.
Insert a. The handle 3 is attached to the other end 4b of the extension pipe 4. That is, by attaching the suction tool 2 directly to the main body 1, or by attaching the handle 3 via the extension pipe 4, the center of gravity becomes close to the suction tool 2.

Next, the case where the center of gravity is located near the handle will be explained using FIG. 6.

Insert one end 4a of the extension pipe into the intake port 1b of the main body 1.
The connecting part 2a of the suction tool 2 is inserted into the other end 4b. Further, the connecting portion 3a of the handle 3 is inserted into the pipe hole 1c of the main body 1. That is, by attaching the suction tool 2 to the main body 1 via the extension pipe 4 (and attaching the handle 3 directly to the main body 1), the center of gravity is located near the handle.

As described above, in the vacuum cleaner of this embodiment, a pipe hole 1c having the same diameter as the suction port 1b is formed at the other end of the main body 1, and a connecting portion 2a having approximately the same diameter as the suction port 1c of the main body 1 is formed in the suction tool 2. The handle 3 is provided with a connecting portion 3a having approximately the same diameter as the pipe hole 1c of the main body 1 (an extension having an outer diameter at one end and an inner diameter at the other end approximately the same as the inlet of the main body) is provided in the handle 3. Therefore, depending on the application, the center of gravity position can be changed by changing the attachment position of the extension pipe 2.

In addition, the extension pipe 4 is also used as a handle between the main body 1 and the handle 3, and as a suction pipe between the main body 1 and the suction tool 2. When changing the center of gravity position, parts can be added or deleted. The position of the center of gravity can be switched without any trouble. There is no chance of accidentally losing the deleted parts. - Rib 1b is installed in the suction port 1c of the main body l, the connection part 2a of the suction tool 2 and the extension pipe 4 By providing a notch corresponding to the rib 1b on one end 4a of the handle 3, it is possible to prevent the connecting portion 3a of the handle 3 from being accidentally inserted into the suction port 1b.

Effects of the Invention The present invention forms a pipe hole with the same diameter as the suction port at the end opposite to the suction port of the main body, a connecting part with approximately the same diameter as the suction port of the main body on the suction tool, and a pipe hole with approximately the same diameter as the pipe hole of the main body on the handle. A connection part with the same diameter is provided, and the extension pipe has an outer diameter at one end and an inner diameter at the other end that are approximately the same as the intake port of the main body, so the installation position of the extension pipe must be changed. By doing this, the center of gravity position can be switched, so depending on the place of use, such as cleaning floors or cleaning high places, the center of gravity can be switched to the position that is easy to use for cleaning.
