Description

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

Structure of the conventional example and its problems In the conventional floor nozzle of this type, as shown in Fig. 1, the joint part connected to the extension pipe a is tiltable, and the angle formed between the extension pipe a and the surface to be cleaned C changes. However, the suction port of the floor nozzle always faces parallel to the surface C to be cleaned, so that stable dust collection performance can be obtained regardless of the body size or posture of the cleaning worker.

However, with a floor nozzle that has a joint part that can be raised and lowered like this, if you try to suck in some large dust from the front, for example, as shown in Figure 2, you have to lift the floor nozzle and place it over the dust. Because it requires manipulation, it can be very difficult to handle.

OBJECTS OF THE INVENTION The present invention eliminates these conventional drawbacks, exhibits stable suction performance, and makes it possible to suction even larger amounts of dust.

Structure of the Invention The floor nozzle for a vacuum cleaner of the present invention is provided with rollers before and after the suction port of the floor nozzle main body having a suction joint that can be raised and lowered, and when the rollers are located near the suction port, the axes of these rollers By setting the roller to be movable so that when it pops out downwards and retracts upwards when it moves away from the suction port, the front side is always held higher than the rear side in the direction of travel, and large dust particles are removed. This facilitates dust collection.

Description of examples Examples thereof will be described below with reference to the accompanying drawings.

In FIGS. 3 to 5, reference numeral 1 denotes a floor nozzle main body formed by connecting upper and lower main body members 2.degree. 3, and a suction joint 4 is attached to the rear interior of the nozzle main body so as to be able to move up and down.

A connecting pipe 5 connected to the suction side of the vacuum cleaner is rotatably attached further to the rear of the suction joint 4. Further, a suction port 6 is provided on the back surface of the lower body member 3, and a ventilation lower is provided in the center thereof, which communicates with the suction joint 4. In the vicinity of the front and rear sides of the suction port 6, there are left and right pairs of front rollers 8 and rear rollers 9.
are provided for each. Axis 1 of front and rear rollers 8 and 9
0° 11 is fitted into the front and rear sliding grooves 12 and 13, respectively, and can slide back and forth within the front and rear sliding grooves 12 and 13. Even if the front and rear sliding grooves 12 and 13 are inclined downward on the side adjacent to the suction port 6 and upward on the opposite side, and the shaft 10.11 is located in the portion that is necessarily upward, At least rollers 8 and 9 are provided at positions that protrude from the bottom surface of the floor nozzle.

In the above configuration, when performing cleaning work, when the floor nozzle main body 1 is operated toward the front as shown in FIG. It moves to a position close to the suction port 6 and close to the bottom of the floor nozzle body 1 (a low position), and as a result, the front of the floor nozzle body 1 is lifted up. Conversely, the shaft 1 of the rear roller 9
1 moves to the rear of the rear sliding groove 13, that is, to a position (higher position) farther away from the horizontal suction port 6 and further away from the bottom of the floor nozzle body 1, and as a result lowers the rear of the floor nozzle body 1. . By operating the floor nozzle body 1 forward as described above, the front of the floor nozzle body 1 is lifted up as shown in FIG. dust collection becomes possible. Similarly, when the floor nozzle main body 1 is pulled rearward, as shown in FIG. 7, the rear part is lifted, making it possible to collect larger dust from the rear part. In this way, a larger amount of dust can be collected simply by moving the floor nozzle body 1 back and forth without requiring any special operations.

Effects of the Invention As described above, according to the present invention, in a floor nozzle having a suction joint that can be raised and lowered, it is possible to collect even larger amounts of dust by simply operating the floor nozzle back and forth.
This makes it possible to improve usability and dust collection performance.

Claims (1)

[Claims] A suction port is formed in the floor nozzle body, which is connected to a suction joint with a connection port to a vacuum cleaner so that it can be raised and lowered freely, and rollers are provided before and after this suction port, and the shafts of these rollers are lower on the side closer to the suction port. Also, the floor nozzle of the vacuum cleaner is movable so that it slides high on the far side.
