[Background of the invention] The applicant for such a vacuum cleaner is applying for the invention patent of the vacuum cleaner (10) shown in FIG. 9 to the Japanese National Patent Office. The dust collecting device (10) has a box body (12); a rotating brush (2) provided in the box body (12); and a dust collecting chamber (3 6) formed inside the box body (12). A motor (32) for rotatingly driving the rotating brush (2) is installed in the box body (12), and a secondary battery (3 3) for supplying power to the motor (3 2). A good garbage suction inlet (3) is opened on the bottom wall (1 4) of the box body (1 2), and a rotating brush storage chamber (3) is formed inside the box body (1 2) for opening the waste suction inlet (3). 9), at the opening edge of the garbage suction inlet (3) located behind the rotating brush (2), a garbage concentration member (31) is protruded toward the floor (5). The four corners of the bottom wall (14) of the box body (12) are provided with a walking roller (4 1) so that the dust collecting device (1 0) can be easily moved. The rotating brush (2) includes a rotating shaft (22), and a brush portion (2 1) formed on an outer peripheral surface of the rotating shaft (22). The rotating shaft (2 2) is connected to the motor (3) using a belt (not shown). 2) The outer peripheral end of the brush part (21) of the rotating brush (2) protrudes slightly from the garbage suction inlet (3). A brush cover wall (93) is provided on the surface of the box body (12) in the rotating brush storage room (39), and the brush cover wall (93) covers the upper part of the rotating brush (2). The dust collection device (10) rotates and drives the rotating brush (2) to sweep up the garbage on the floor (5) and accumulates the dust collection chamber (36) from the garbage suction inlet (3) through the airflow passage (34). ). However, the vacuum device (丨 〇) is shown in Figure 丨 〇, because with the rotation

313701.ptd Page 6 1240622 V. Description of the invention (2) The rotation of the brush (2) will generate a swirling flow as shown by the arrow in the vacuum chamber (3 6), so the garbage suction inlet (3) passes through the airflow passage ( 3 4) The airflow flowing into the dust collecting chamber (3 6) is reduced and there is a problem that the dust collecting efficiency is low. In addition, as the rotating brush (2) rotates in the counterclockwise direction as shown by the arrow, a gap W is formed between the brush cover wall (9 3) and the outer peripheral end portion of the brush portion (2 1) of the rotating brush (2), When the air is drawn in as shown by the arrow, the air drawn in from the garbage suction inlet (3) becomes the airflow blowing out of the dust collection device, and the garbage (5 3) on the floor (5) is blown out as shown by the arrow Question of direction. The garbage swept up by the rotating brush (2) is caught in the gap w, and there is a situation in which it cannot be caught in the vacuum chamber (3 6). Furthermore, the airflow flowing from the garbage suction inlet (3) collides with the end (93a) of the brush cover wall (93), as shown by the arrow, a turbulent airflow is generated, which reduces the amount of airflow into the dust collection chamber (36). The air flow rate has the problem of low dust collection efficiency. It is therefore an object of the present invention to provide a dust suction device which is higher than the previous dust suction efficiency. The dust suction device of the present invention is provided with a garbage suction inlet (3) on the bottom wall (1 3) of the box body (1 1), and a rotating brush storage room (3 9) and dust collection are also provided inside the box body (丨 丨). The rotating brush receiving chamber (3 9) is connected to the dust collecting chamber (36) through the airflow passage (34). The rotating brush storage room (39) is equipped with a rotating brush (2). The outer peripheral end (2 丨 a) of the rotating brush (2) faces the garbage suction inlet, and the floor is swept up according to the rotation of the rotating brush (2). The upper garbage can pass through the airflow passage (3 4) and can be concentrated in the dust collecting chamber (3 6). A brush cover wall (8 3) covering the upper part of the rotating brush (2) is arranged on the box body (1 1) facing the rotating brush receiving room (3 9), and the rotating brush receiving room (3 9) and dust are sucked to (3 6). ), Stands from the bottom wall of the box (1 1).

313701.ptd Page 7 1240622 V. Description of the invention (3) The airflow of the dust suction inlet (3) is roughly directed to the airflow guide wall (8 1) in the vertical direction. The airflow passage (3 4) is formed between the upper end portion (8 1 a) of the airflow guide wall (8 1) and the dust chamber side end portion (8 3 a) of the brush cover wall (8 3) ° In the above-mentioned vacuum cleaner of the present invention, the airflow flowing in from the garbage suction inlet (3) is induced along the wall surface of the airflow guide wall (8 1) approximately vertically upward, and flows into the dust collection chamber (3 6) to make the airflow The direction is the same as that of the same direction, which can prevent the rotating airflow generated in the vacuum cleaner from being generated by the previous vacuum cleaner. In accordance with this, the flow of the airflow is increased, and a suction airflow is generated at the garbage suction inlet (3). As a result, its dust collection efficiency is higher than that of the previous dust collection device.

Based on the specific structure, the brush cover wall (83) of the box body (11) is formed in the rotary shaft (22) of the rotating brush (2) and a coaxial cylindrical surface, and is formed on the brush cover wall (8 3 ) And the gap g between the outer peripheral end (2 1 a) of the rotating brush (2) is set to be smaller than that formed between the airflow guide wall (8 1) and the outer peripheral end (2 1 a) of the rotating brush (2) Gap d. According to this specific configuration, there is a gap g between the narrow brush cover wall (8 3) and the outer peripheral end portion (2 1 a) of the rotating brush (2), so the amount of air entrained in the gap g is extremely small. Therefore, with the rotation of the rotating brush (2), the air flow rate blown out from the dust suction inlet (3) in front of the dust suction device will be sufficiently reduced. In addition, the amount of air involved in the gap g is extremely small, so

The amount of waste is greatly reduced. Furthermore, in a specific configuration, a garbage blocking wall (70) is protruded toward the pressing portion of the dust collection chamber (36) on the upper end portion (81a) of the airflow guide wall (81). According to this specific structure, when the dust collection chamber (36) is erected above the rotary shaving storage chamber (39), the garbage in the dust collection chamber (36) moves on the airflow guide wall (8 丨). But above the airflow guide wall (6 1)

1240622 V. Description of the invention (4) Part (81a), because a garbage blocking wall (70) is protruded into the interior of the vacuum chamber (36), the garbage on the airflow guide wall (6 1) is based on the garbage. It is blocked by the living wall (70) so as not to fall from the airflow passage (34). This is done so as to prevent the backflow of the rotating brush receiving chamber (39) to the garbage in the dust collecting chamber (36).

As described above, according to the dust suction device of the present invention, there is a sufficient flow of air flowing into the dust suction chamber through the waste suction inlet, so a suction suction flow is generated at the waste suction inlet, and the garbage on the floor is sucked into the dust suction room according to the suction suction flow . In addition, the amount of airflow blown out from the garbage suction inlet to the front of the dust collector is sufficiently small, so there is no concern that the garbage will be blown in front of the dust collector. As a result, the dust collection efficiency is higher than that of the conventional dust collector.

When storing the vacuum cleaner (1), as shown in FIG. 8, since the box (1 1) is self-standing, the position of the vacuum chamber is located above the rotating brush storage chamber (39), and is stored in the box (11). Although the garbage (63) on the bottom wall (13) moves on the wall (80) of the airflow guide wall (8 1) as shown in FIG. 8, the garbage backflow prevention valve (7 1) is connected with the dust collection operation and stops. At the same time, the airflow passage (3 4) is blocked, so the garbage (5 3) is blocked by the garbage backflow prevention valve (7 1) and will not fall from the air flow passage (3 4). This is to prevent the garbage from flowing back to the rotating brush storage chamber (39) during storage. Still, the garbage backflow prevention valve (7 1) has a strength that does not cause large deflection according to the weight of the garbage, and at the same time, the free end (71b) needs to be formed so as not to exceed the upper end portion (8) of the airflow guide wall (8 1). 1 a) while moving to the side of the rotating brush storage chamber (3 9), and overlapping the upper end portion (81a) of the airflow guide wall (8 1) with a sufficient area. In the third embodiment and the fourth embodiment, the description is based on the case where the vacuum cleaner is accommodated. However, when the vacuum cleaner is transported while standing, it has the same function as the vacuum cleaner. 6) The garbage (5 3) in the counter current flows in the rotating brush storage chamber (3 9). Furthermore, in the posture of the vacuum cleaner as shown in FIG. 5 and FIG. 7, the garbage (5 3) jumping up in the vacuum chamber (3 6) in a situation such as a step difference is blocked by the garbage. (7 〇) or garbage backflow prevention 阙 (7 1) catch, so the garbage (5 3) is prevented from passing through the gas

313701.ptd Page 16 1240622 V. Description of the invention (12) The flow passes through the port (3 4) and flows countercurrently in the rotating brush storage chamber (3 9). However, the constitution of each part of the present invention is not limited to the constitution of the above embodiment, and various modifications can be made within the scope of the technology described in the scope of patent application. For example, the rotating brush is not limited to a component that is driven and rotated by the rotation of a motor, and is rotated by a rotational force given by an airflow. The so-called rotating brush may also be configured to use a turbo-brush. It is also possible to use a combination of a motor and an absorption fan.
