In this embodiment, an example is shown in which the support portion 24 is integrally provided on the case 20. The support portion 24 is arranged, for example, behind the suction port 12.

The roller 25 is rotatably supported by the support portion 24. For example, the roller 25 is rotatable in both directions. The roller 25 is arranged behind the suction port 12. The rotating brush 22 is arranged in front of the roller 25. At least a part of the suction port 12 is arranged between the rotary brush 22 and the roller 25. The roller 25 includes, for example, a shaft body 28, a flocking 29, and a flocking 30. The roller 25 is an example of a roller having a plurality of types of flocking. In the present embodiment, as the simplest example, an example in which the roller 25 includes two types of flocking is shown. The roller 25 may be provided with three or more types of flocking.

The shaft body 28 is a rotation shaft of the roller 25. The shaft body 28 is rotatably supported by the support portion 24. The shaft body 28 is arranged in parallel with the rotating shaft 26 of the rotating brush 22, for example. The flocking 29 is an example of the first flocking, and is provided on the shaft body 28. The flocking 30 is an example of the second flocking, and is provided on the shaft body 28. The shaft body 28 is covered with flocking 29 and flocking 30.

That is, at least a part of the roller 25 projects downward from the lower surface of the case 20.

In the examples shown in FIGS. 4 and 5, the flocked 29s are arranged in a spiral shape. The flocking 30 is arranged so as to cover the entire shaft body 28. The area where the flocked 30 covers the shaft body 28 is wider than the area where the flocked 29 covers the shaft body 28.

The flocking 29 is a flocking of a specific specification. The flocking 30 is a flocking of a specific specification. The specifications of the flocked 29 are different from the specifications of the flocked 30. An example in which the specifications of the flocking 29 are different from the specifications of the flocking 30 will be described in detail below.

For example, the flocked 29 has a hardness different from that of the flocked 30. The flocked 29 may have a length different from the length of the flocked 30. The hardness and length of the flock 29 may differ from the hardness and length of the flock 30. For example, the flocked 29 is longer and softer than the flocked 30. In such a case, the flocking 29 can ensure the sealing property with the floor. Further, when the suction tool 2 advances backward, the dust that has entered the inside of the carpet or the like can be scraped out by the flocking 30.

As another example, the flocked 29 may have a shape different from the shape of the flocked 30. For example, the flocked 29 is straight hair and the flocked 30 is curly. In such a case, the flocking 29 can ensure the sealing property with the floor. In addition, the flocking 30 can entangle and capture dust. The flocked 29 may be curly and the flocked 30 may be straight.

As another example, the specifications may differ depending on whether or not it has the effect of suppressing the action of a specific allergic substance such as pollen or dead mites. For example, the flocked 29 is subjected to a specific treatment for suppressing the action of allergens. The flocking 30 is not subjected to a specific treatment for suppressing the action of allergens. The above-mentioned "suppressing the action of allergens" means, for example, converting allergens into harmless proteins. In this example, the flocking 30 can be specialized for other functions. For example, the flocking 30 may ensure the sealing property with the floor. The flocking 30 may be subjected to a specific treatment for suppressing the action of allergens, and the flocking 29 may not be subjected to a specific treatment for suppressing the action of allergens.

As another example, the specifications may differ depending on whether or not it has the effect of preventing charging. For example, the flocking 30 has a surface resistance value lower than the surface resistance value of the flocking 29. In this example, the flocked 29 can be specialized for other functions. For example, the flocking 29 may be used to ensure the sealing property with the floor. The flocked 29 may have a surface resistance value lower than the surface resistance value of the flocked 30.

As another example, the density of the flocked 29 and the density of the flocked 30 may be different values. For example, the density of the flocked 30 is higher than the density of the flocked 29. In this example as well, the flocking 29 can be specialized for other functions. For example, the flocking 29 may be used to ensure the sealing property with the floor.

In the example shown in this embodiment, the roller 25 includes a plurality of types of flocking having different specifications. Therefore, in the example shown in the present embodiment, the roller 25 can be provided with various functions according to the specifications of flocking.

The other functions that can be adopted by the suction tool 2 will be described below. If possible, the suction tool 2 may be adopted by combining a plurality of functions shown below.

In the present embodiment, an example in which the roller 25 can rotate in both directions has been described. This is just an example. For example, the roller 25 may be rotatable in only one direction. The suction tool 2 may include means for switching the rotation direction of the roller 25.

For example, the support portion 24 supports the shaft body 28 so that the roller 25 rotates when the case 20 moves rearward while the suction tool 2 is placed on the floor. The support portion 24 supports the shaft body 28 so that the roller 25 does not rotate when the case 20 moves forward while the suction tool 2 is placed on the floor. In this example, when the suction tool 2 is moved forward, the floor surface can be wiped by the flocking 29 and the flocking 30, and when the suction device 2 is moved backward, the dust captured by the flocking 29 and the flocking 30 is sucked. Can be done. In this example, the density of the flocked 30 may be higher than the density of the flocked 29 in order to enhance the dust wiping effect. Similarly, in order to enhance the effect of wiping dust, the flocked 29 may be straight and the flocked 30 may be curly.

In the present embodiment, an example in which the flocking 29 is arranged in a spiral shape has been described. This is just an example. FIG. 8 is a bottom view showing another example of the suction tool 2. FIG. 8 shows an example in which the flocked 29 is arranged in a straight line. The flocked 29 is arranged in a straight line so as to be parallel to the shaft body 28. Also in the example shown in FIG. 8, the flocking 30 is arranged so as to cover the entire shaft body 28.

FIG. 9 is a bottom view showing another example of the suction tool 2. In the example shown in FIG. 9, the flocking 29 is provided at the central portion of the shaft body 28 in the longitudinal direction. The flocking 30 is not provided at the central portion of the shaft body 28 in the longitudinal direction. On the other hand, the flocking 30 is provided at one end and the other end of the shaft body 28. Flocking 29 is not provided at both ends of the shaft body 28. The flocking 29 is arranged between the flocking 30 provided at one end of the shaft body 28 and the flocking 30 provided at the other end of the shaft body 28.

In the example shown in FIG. 9, the density of the flocked 30 may be higher than the density of the flocked 29 in order to enhance the dust wiping effect at the end of the roller 25. Similarly, in order to enhance the effect of wiping dust at the end of the roller 25, the flocked 29 may be straight and the flocked 30 may be curly.

In the present embodiment, an example in which the rotary brush 22 is driven by the motor 23 has been described. This is just an example. The rotary brush 22 may be rotationally driven by, for example, an air flow generated when the blower 9 is driven.

As described above, in the example shown in the present embodiment, the roller 25 can be provided with various functions according to the specifications of flocking. Therefore, for example, as a sales form of the vacuum cleaner 1, a plurality of rollers 25 may be included in one vacuum cleaner 1.
