Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a floor suction tool for a vacuum cleaner.

Structure of conventional example and its problems In this type of conventional floor suction tool, as shown in Fig. 1, the joint part b that connects to the extension pipe a is tiltable.
Even if the angle with the surface to be cleaned changes, the dust suction surface of the suction device is always in horizontal contact with the surface to be cleaned, ensuring stable dust suction performance regardless of the height or posture of the person cleaning. It is possible. However, in recent years, especially with the spread of carpets, the ability to freely raise and lower the joint portion has been causing a decrease in dust suction performance, depending on the type of carpet. The reason for this is as follows: when using a long-pile carpet, the suction force of the suction tool does not work very well on the carpet, and as a result, the suction tool as a whole feels fluffy and does not touch the carpet surface. It becomes a stroked shape. If you try to press the entire suction tool against the floor, the front part of the suction tool will float as shown in Figure 2 because the vertically movable joint part b is at the rear of the suction tool, which will further deteriorate the dust suction performance. Furthermore, if the suction power of the vacuum cleaner body decreases, the above phenomenon will occur even if the bristles of the carpet are not very long.

As mentioned above, when the suction power of the vacuum cleaner body is strong and the suction power of the suction tool to the surface to be cleaned is strong, when cleaning carpets with not very long piles, floor tatami mats, etc. Jizai is very effective as it provides stable dust suction performance due to the suction power of the suction tool, but
On the contrary, it was ineffective when using carpets with long piles or when the suction power of the main unit was reduced.

OBJECTS OF THE INVENTION The present invention solves these conventional drawbacks and provides a floor suction tool for a vacuum cleaner that is easy to use.

Composition of the Invention The floor suction tool of the present invention has a suction joint having a connection port to the vacuum cleaner side provided at the rear of the main body of the suction tool so as to be able to move up and down, and this suction joint has one or more cutouts. A cutout groove is provided, and a stopper that is detachably engaged with the cutout groove is formed on a stop lever movably provided in the main body.
Therefore, during normal cleaning work, the suction joint can be raised and lowered to face the surface to be cleaned, and when cleaning long pile carpets, etc., the stop lever can be operated and the stopper By engaging the suction joint with the notch groove, the vertical movement of the suction joint can be locked and its cleaning can be performed reliably.

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

In Figures 3 to 5, reference numeral 1 denotes a floor suction tool body, behind which a suction joint 2 is attached so as to be freely tiltable, and furthermore, a rotary pipe 3 is rotatably attached to the suction joint 2. . Reference numeral 4 denotes a lower portion of the suction tool body, and a brush body 6 in which brushes 5 are implanted is attached inside this body. The hole 7 of the brush body 6 is slidably fitted into a boss 8 formed on the lower part 4 of the suction tool body. Further, a boss 9 formed on the brush body 6 is slidably fitted into a cam groove 11 formed on the switching lever body 10. In addition, a notch groove 12 is formed in the suction joint 2, and a stopper 1 of a stop lever 13 that is slidable in the left and right direction is formed in the suction joint 2.
4 is configured to be removably engaged.

In the above configuration, when the switching lever body 10 is operated, the boss 9 moves along its cam groove 11, thereby causing the entire brush body 6 to move up and down.

Next, when cleaning, the entire suction tool is attracted to the surface to be cleaned by the suction force of the vacuum cleaner body, and this causes the extension pipe (not shown) connected to the rotary pipe 3 to Since the suction joint 2 can be raised or lowered even if the angle changes slightly, the suction tool is always attracted to the surface to be cleaned, and stable dust suction performance can be obtained regardless of the height or posture of the person cleaning.

However, if the surface to be cleaned is difficult to absorb, or if the carpet has long bristles, the suction will not work, so the entire suction tool will be stroking the carpet, and the suction will get deep into the hair. I can't breathe in the dust that comes out. Therefore, if an attempt is made to press the entire suction tool against the surface to be cleaned, since the suction joint 2 is located at the rear of the suction tool, the front part of the suction tool will float, further reducing the dust suction performance. In addition, when the suction power of the vacuum cleaner body decreases and the suction power of the suction tool to the surface to be cleaned becomes weak, the suction device will be in a state of stroking the surface to be cleaned, as described above, and the degree of sealing to the surface to be cleaned will be reduced. If the suction tool is pressed down to increase the amount of dust, the front part of the suction tool will float as described above, reducing the dust suction performance.

Therefore, in this embodiment, when the stopper 14 of the stop lever 13 is fitted into the notch groove 12 formed in the suction joint 2, the suction joint 2 is completely fixed, so as mentioned above, the suction joint 2 is completely fixed. Even if the suction device is pressed down, the front of the suction device will not float up.
Dust absorption performance can be improved. Also, as shown in Figure 6, if the suction joint 2 is provided with many notched grooves 12 so that it can be fixed in multiple stages, the angle can be set arbitrarily to suit the person cleaning, making it even more effective. Become. In addition, when sucking in large dust, it is impossible to suck up large dust if the suction tool is horizontal to the surface to be cleaned. Dust was sucked by placing the suction device on it, but once the suction joint 2 is fixed, the extension pipe can be folded down as shown in Figure 7, and the front of the suction device can be lifted up, making it easy to suck in large dust. be able to.

Effects of the Invention As described above, according to the present invention, dust can be reliably sucked by making the suction joint vertical or fixed depending on the condition of the surface to be cleaned, etc., and the usability is also significantly improved. It's something you get.
