Description

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

2. Description of the Related Art Conventionally, some suction tools for vacuum cleaners of the vacuum suction type have the function of scraping up dirt and polishing the floor by rotating a brush or a wiping member using a motor. With this configuration, for example, you can scrape up and suck up cotton waste entangled in a long-pile carpet.
It can also suck up dirt while wiping dirt off the floor.

Problems to be Solved by the Invention By the way, the suction tool of such a vacuum cleaner is used by moving it back and forth on the floor, but if it is equipped with a rotating brush or wiping member as mentioned above, Since the frictional resistance with the floor is large, there is a large resistance when the suction tool moves back and forth. Furthermore, when moving the device over a carpet with long piles, the frictional resistance increases, making it difficult for the user to use the device.

The present invention has been made in view of this problem, and an object thereof is to provide a suction tool for a city air cleaner that can be moved back and forth with a light force.

Means for Solving the Problems In order to solve the above problems, the present invention provides a traveling device driven by a motor.1.11 Electricity 4; A slide member held slidably and relative movement of the slide member with respect to the main body! 6, a means for detecting the direction thereof, and a drive control means for rotating the motor for causing the main body to travel so as to follow the sushi 1 and the member according to the detection output thereof.

By virtue of the structure as described above, when force is applied to the connecting pipe to move the main body in the +iif direction or backward, the connecting pipe and the slide I/member move relative to the main body, and the main body moves in the same direction. To make the main body travel, the motor rotates to assist in moving the main body.

Examples Examples of the suction device of the present invention will be described below. Second
The figure is a perspective view of the suction tool of this embodiment, and in FIG. It is a connecting pipe. A slide member 3 is slidably held in a portion of the main body case 1, and the connecting pipe 2 is rotatably held by the slide member 3.

FIG. 1 does not show the internal structure of the suction tool of this embodiment. In FIG. 1, 6 is a suction provided at the bottom. Reference numeral 7 indicates a wiping member having a cylindrical shape and is rotatably provided in the center of the suction port 6, and 8 indicates a rotation axis of the wiping member 7. 10 is a motor for rotating the wiping member 7; 12 is a power transmission gear I;
The rotational force is transmitted to the rotating shaft 8 to rotate the wiping member 7.

FIG. 3 is a bottom view of the present suction tool. In FIG. 3, 13 and 14 are bells provided as traveling devices,
They are arranged near both ends of the suction port 6, and a portion is exposed from the bottom. As shown in Figure 2, Hell 1 ↓ 3 is the wheel 15,
The suction device is attached to the pump 6, and the helmets 1 and 14 are also attached to other Kai 1 and river wheels (not shown), and this suction tool can be moved by the rotation of the helmets 3 and 14.

18 is a motor for rotating the holding guide transport 15, 19 is an output shaft 1 of the motor 18, and 20 is a gear section for transmitting the rotation of the output shaft 19 to the kite transport 15. Reference numeral 21 denotes a spring for keeping the slide member 3 positioned at the center of its movement range when no force is applied.

Next, the drive control means will be explained. In other words, 22 is a printed wiring board for switching provided on the slide member 3, and 23 is a movement detection section equipped with a contact that can come into contact with a conductive foil on the printed wiring board 22.

FIG. 4 shows the arrangement of the printed wiring board 22 and the movement detection section 23. 25, 26, and 27 are the aforementioned contacts. 28 and 29 are conductive parts (indicated by diagonal lines) formed on the printed wiring board 22, and 30 is a current power source 11C for driving the motor 8. The conductive part 28 is connected to the positive electrode side of the DC power supply 30, and the conductive part 29 is connected to the positive electrode side of the DC power supply 30.
connected to the negative pole side of the

The operation will be explained below. FIG. 4 shows the stationary state, in which the contacts 25, 26, and 27 are all open. For example, assume that a force is applied to the sliding member 3 that is being moved forward, and that force causes the printed wiring board 22 to move somewhat in the eight directions of the arrows relative to the movement detection section 23. When the printed wiring board 22 moves in the direction of arrow A,
The contact 25 contacts the conductive part 28, and the contact 26 contacts the conductive part 29, causing the motor 18 to rotate in the forward direction. Then, when the main body case 1 moves somewhat, the contacts 25 and 26 are opened again, and the motor 18
is stopped. Further, when a force is applied to the slide member 3 to move it backward, the printed wiring board 22 will move in the direction of arrow B with respect to the movement detection section 23. Then, the contact 26 comes into contact with the conductive part 28, and the contact 27 comes into contact with the conductive part 29, and the motor 18 rotates in the backward direction.

5 6 Also in this case, when the main body case 1 moves a certain amount, the contacts 26 and 27 are opened again and the motor 18 is stopped.

In this embodiment, as described above, the bell l-13. Since the rotation direction of the motor 1 and ] 4 is configured to be switched, there is no need for the user to manually switch the rotation direction of the motor.

Effects of the Invention As described above, the present invention includes a traveling device driven by a motor, a connecting pipe for guiding air to the vacuum cleaner, and a slide member that is slidably held in the main body. By providing a means for detecting the relative movement and direction of the sliding member with respect to the main body, and a drive control means for rotating the motor to cause the main body to travel so as to follow the sliding member in accordance with the detection output thereof. When a force is applied to the connecting pipe to move the main body forward or backward, the connecting pipe and the sliding member move in line with the main body, and when that movement is detected, the connecting pipe and the sliding member follow the sliding member. The above-mentioned motor rotates to make the main body travel, thereby assisting the movement of the main body. Therefore, even if it is equipped with a rotating brush or a wiping device, the user can move the suction device back and forth with very light force, and it can be moved with good force even on long pile carpets. It is possible to reduce the amount of labor required by the user. Moreover, by having such a traveling device, even if there is a sheet that sticks to the suction port and is difficult to remove, the traveling device can move the sheet while pulling it away from the suction port, increasing the suction power. It is possible to clean the bedclothes in the same state, and it is also effective in exterminating dust mites.
