Description

Suction brush mounting structure of vacuum cleaner

The present invention relates to a suction brush mounting structure of a vacuum cleaner, and more particularly, by moving the drive motor mounting position inside the suction brush to reduce the overall size of the suction brush to facilitate the use and improve the durability. In addition, the present invention relates to a suction brush mounting structure of a vacuum cleaner which is improved to achieve cost reduction by shortening the number of parts and the assembly process.

Generally, the vacuum cleaner has a dust collecting chamber and a driving chamber partitioned by an inner partition wall, and a main body which is movable by a wheel, and a suction brush that sucks dust at one end thereof are detachably attached and the suction force is adjusted at the other end. Flexible hoses are provided with a handle having a switch part and connected to the casing at multiple stages, and a flexible hose that is coupled to the connector at the end to be freely attached to the dust collecting chamber in the body part while forming an air passage coupled to the extension pipe. Hose), and the front end of the extension tube is provided with a suction brush in contact with the cleaning surface to suck foreign matters such as dust.

As shown in FIG. 1, the suction brush 100 used in the vacuum cleaner is rotatably installed with the rotating rod 113 attached to the sole 112 in a spiral manner in the lower case 110. In addition, one side of the driving motor 114 is installed on the support ribs 120, and the other side of the circuit board 122 having a fuse (121) is installed by a screw 123. In addition, the driving motor 114 and the rotating rod 113 having the rotating shaft 114a are connected to the belt 115, and rollers 116 and 116 'are provided on both sides of the lower surface front of the lower case 110. The upper case 119 is rotatably coupled and the upper case 119 to which the suction pipe 118 is connected and fixed to the main inlet 117 is fixed to the lower case 110.

Then, when the rotary brush of the general vacuum cleaner rotates the drive motor 114, the rotational force of the drive motor 114 is transmitted to the rotating rod 113 through the belt 115, the rotation of the rotating rod 113 The brush 112 shakes off the dust and the like, and the dust is collected through the suction hole 124 and the suction pipe 118 of the lower case 110 to the dust collecting chamber built in the vacuum cleaner body.

Meanwhile, FIG. 2 illustrates a state in which various components are mounted on the lower case 110 before the upper case 119 and the suction pipe 118 are mounted. That is, in the lower case 110, the circuit board accommodating chamber 130 and the driving motor accommodating chamber 131 are formed at both sides of the main suction opening 117, and thus the accommodating chambers 130 and 131 are formed. The volume occupied becomes an element for determining the overall size of the suction brush 100. However, the drive motor 114 mounted in the drive motor accommodating chamber 131 occupies most of the space part of the drive motor accommodating chamber 131, and as described above, the size of the suction brush is reduced. Although it is essential to reduce the volume of the storage chambers 130 and 131, there is a problem that the reduction of the driving motor storage chamber 131 is not easy.

In addition, in the conventional structure as described above, the belt 115 is often broken, and in this case, the durability of the rotating brush is significantly reduced. In addition, since the assembly process and parts are required a large amount, there is a problem that leads to an increase in manufacturing cost.

The present invention is to solve the conventional problems as described above, the purpose is to reduce the overall size of the suction brush by using a belt or the like in the suction brush to facilitate the use, improve the durability, It is to provide an improved suction brush mounting structure of the vacuum cleaner to achieve cost reduction by shortening the number of parts and the assembly process.

In order to achieve the above object, the present invention, in the rotary brush structure in which a motor or the like is mounted in the suction brush of the vacuum cleaner, the rotating rod is formed to be rotatable across the suction hole of the lower case is rotatably mounted, The rotary shaft of the motor formed on one side of the suction hole is directly connected to the central shaft of the rotating rod to provide the suction brush mounting structure of the vacuum cleaner, characterized in that for rotating the rotating rod in the suction hole by the rotation operation of the motor. All.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

In the suction brush mounting structure 1 of the vacuum cleaner according to the present invention, as shown in FIG. 3, the rotating rod 12 that forms the brush 12a across the suction hole 24 of the lower case 10 rotates. It is mounted to be possible, and has a structure in which the rotary shaft (15a) of the motor 15 formed on one side of the suction hole 24 is connected in direct connection to the central axis of the rotary rod 12.

Rotating brush mounting structure (1) of the present invention is the upper case 19 and the lower case 10 is coupled to each other, the rotating rod 12 so as to traverse it in the suction hole 24 of the lower case 10 Is mounted, the outer circumferential surface of the rotary rod 12 has a structure in which the bristle brush (12a) is formed integrally. The rotary rod 12 is fitted such that the shaft 13 at one end thereof is rotatable through the one bearing 22a, and the other side of the rotary rod 12a is the center of the bearing 22b of the motor 15. It penetrates and is connected to one side of the rotating rod 12 by penetrating. The bearings 22a and 22b are inserted into and fixed to the grooves 25a and 26a provided in the side ribs 25 and 26 of the lower case 10, and the motor is provided on one side of the suction hole 24. The storage chamber 30 is formed. A small motor 15 is placed in the motor storage chamber 30, and a bearing of the partition 26 in which the rotation shaft 15a of the motor 15 separates the suction hole 24 and the motor storage chamber 30. The rotational force of the motor 15 can be transmitted to the rotating rod 12 by extending through the 26a and being pressed into the central axis of the rotating rod 12.
