Abstract

(57) [Summary] [Purpose] To provide a vacuum cleaner capable of lifting and suctioning dust, etc. stuck in the depths of tatami mats. [Structure] A rotating shaft 8 rotated by a motor 7 and a vibrating member 10 are provided inside an attachment 5 that can be attached to and detached from a suction port of a vacuum cleaner body. The vibrating member 10 is supported at one end 11. The vibrating member 10 also includes a floor vibrating surface 13 that is exposed from the suction port 6 and comes into contact with the floor surface. On the other hand, the rotary shaft 8 is provided with a convex portion 16 on its circumferential surface that hits the other end 12 of the vibrating member 10. When the motor 7 rotates, the protruding portion 16 hits the vibrating member 10, and the vibrating member 10 is moved to the supported end 11.
It vibrates using the fulcrum as a fulcrum. As a result, the floor vibrating surface 13 violently hits the floor surface.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a vacuum cleaner.

0002

[Conventional technology]

Various proposals have been made to improve the suction ability of vacuum cleaners. There is. For example, there is one shown in Japanese Patent Publication No. 54-24221. This issue A rotating brush that is rotatably supported on the air intake port of a vacuum cleaner, and this rotating brush. and a striking body that rotates integrally with the striking body. The rotating brush and striking body are The carpet is stirred up and struck by the rotation of the rug. As a result, the carpet It easily sucks up dust that has penetrated deep into the carpet as well as dust that has adhered to the carpet. This has the advantage that dust collection efficiency can be greatly improved. however, If you use this vacuum cleaner on a tatami floor, it will remove the dust that is stuck inside the tatami mats. There are concerns that it will not be possible to stir up the water sufficiently.

0003

[Problem that the idea aims to solve]

The present invention was made in consideration of this point, and it is designed to prevent dust and other particles from getting stuck in the depths of the tatami mats. The purpose is to provide a vacuum cleaner that can lift and suction.

0004

[Means to solve the problem]

This invention consists of a suction port that opens toward the floor, and a cylindrical structure provided inside the suction port. It consists of a rotating shaft and a cantilevered vibrating member with one end supported on the periphery of the suction port. The rotating shaft has a protruding portion on its circumferential surface that hits the other end of the vibrating member; The vibrating member includes a floor vibrating surface exposed within the suction port and in contact with the floor surface.

[0005]

[Effect]

According to the present invention, the protruding portion provided on the rotating shaft strikes the other end of the vibrating member. child At this time, the vibrating member vibrates using one end supported by the periphery of the suction port as a fulcrum. this vibration is also transmitted to the floor vibrating surface exposed inside the suction port, hitting the floor violently. the result, Dust that is stuck deep inside the floor surface rises to the surface and is sucked in to improve dust collection efficiency. will improve.

【Example】

Embodiments of the present invention will be described in detail below with reference to the drawings.

[0007] 1 is the main body of the vacuum cleaner, which includes a Ni-Cd battery for driving and a fan module for suction. (not shown). There is also a power switch on the handle 2 of the vacuum cleaner body 1. A switch 3 is slidably provided. When the power switch 3 is turned on, the The attachment (described later) provided at the tip of the vacuum cleaner body 1 rotates when the motor rotates. Dust and the like are sucked in from the mounting port 4 along with outside air. suctioned dust The dust is collected in a paper pack (not shown) detachably provided in the main body 1. Also a book The charging terminal of the Ni-Cd battery is exposed on the back side of the body 1, The main body 1 is mounted on a dedicated charging stand to charge the Ni-Cd battery.

[0008] Reference numeral 5 designates an attachment that is detachably attached to the attachment port 4. This a The attachment 5 is provided with a suction port 6, and when the attachment 5 is installed, the suction port 6 is provided. The entry port 6 communicates with the mounting port 4. Inside attachment 5, A motor 7 and a cylindrical rotating shaft 8 are provided, and the motor 7 and the rotating shaft 8 are connected to each other by a transmission belt. They are connected to each other by a joint 9. Furthermore, inside the attachment 5, the vibration member 10 is installed. It is provided near the suction port 6. This vibrating member 10 is made of a bent resin plate. shape, and one end 11 is screwed to the inner surface of the attachment 5. Then, the other end 12 is bent inward of the attachment 5 and supported on a cantilever. There is. In addition, the vibrating member 10 is integrally formed with a floor vibrating surface 13 exposed inside the suction port 6. Ru. This floor vibrating surface 13 is equipped with nine gratings 14 having a plurality of openings. Said shake The other end 12 of the moving member has a slit 15 for each grid 14, and the other end 12 has a slit 15 for each grid 14. It is divided into 9 parts. On the other hand, the rotating shaft 8 has a pair of protrusions 16 formed on its circumferential surface. The protruding portion 16 hits the other end 12 of the vibrating member 10 when the rotating shaft 8 rotates. It is placed in a position where

[0009] By the way, the attachment 5 is arranged so that the power supply terminal of the motor 7 is exposed. On the other hand, the vacuum cleaner main body 1 takes out the output of the Ni-Cd battery. It is provided so that the external terminal is exposed. Attachment 5 to vacuum cleaner body 1 When attached, the power supply terminal and external terminal are connected, and the power switch 3 can be operated. The motor 7 rotates when the switch is ON in conjunction with the switch.

0010 In the above configuration, the attachment 5 is attached to the vacuum cleaner body 1, and the power supply is When the switch 3 is turned on, the fan motor rotates and the Outside air is sucked through the suction port 6. At this time, power is also supplied to the motor 7, and the motor 7 rotates. When the motor 7 rotates, the protruding portion 16 provided on the circumferential surface of the rotating shaft 8 moves forward. The other end 12 of the vibrating member 10 is struck. The vibration member 10 is attached to the inner surface of the attachment 5. It vibrates using the screwed end 11 as a fulcrum. This vibration is also transmitted to the floor vibration surface 13. is reached, and the floor vibrating surface 13 violently hits the floor surface in short cycles. As a result, for example, tatami floors When cleaning the surface of the tatami, the dust and other particles trapped deep inside the tatami mats can be shaken off by strong vibrations. 14, and the vacuum cleaner main body 1 sucks it from the second suction port 6.

[0011] In this embodiment, the protruding portion 16 and the other end 12 of the vibrating member 10 are formed in a straight line. However, for example, by forming the protruding part 16 in a spiral shape along the circumferential surface of the rotating shaft 8, the protruding part 16 can be formed into a spiral shape. It is also possible to make the impact by the part 16 continuous and uniform. In this case, the rotation The rotation unevenness of the shaft 8 is made uniform, and the suction action can be stabilized.

0012 Furthermore, in this embodiment, the motor 7, the rotating shaft 8, and the vibrating member 10 are It is provided in the attachment 5, and the attachment 5 is detachably attached to the vacuum cleaner body 1. However, these may be built into the main body 1 in advance.

[0013]

[Effect of the idea]

According to the present invention, the protruding portion provided on the rotating shaft strikes the other end of the vibrating member. child At this time, the vibrating member vibrates using one end supported by the periphery of the suction port as a fulcrum. this vibration is also transmitted to the floor vibrating surface exposed inside the suction port, hitting the floor violently. the result, Dust that is stuck deep inside the floor surface rises to the surface and is sucked in to improve dust collection efficiency. will improve. Therefore, conventional rotating brushes and striking bodies cannot collect dust sufficiently. It can collect dust that is stuck in the depths of the tatami mats.
