The present invention relates to a vacuum cleaner, and more particularly, to a shoulder strap fixing structure of a vacuum cleaner capable of carrying a cleaner body on a shoulder.

In general, a vacuum cleaner is a cleaning device that automatically removes dust and the like by a strong suction force by a fan motor, and a representative structure thereof is shown in FIG. 1.

The air inlet 2 is formed at the front of the cleaner main body 1 in which the wheel is installed at the bottom and the dust collecting chamber 8 and the fan motor 9 are installed therein, and the air inlet 2 has a flexible suction pipe ( One side of 3) is mounted, and the other side of the flexible suction pipe 3 is connected to one side of the handle 4.

One side of the multistage extension tube 5 is connected to the other side of the handle 4, and the brush assembly 6 is connected to the other side of the multistage extension tube 5, and the cleaner body 1 is connected to the upper surface of the handle 4. The switch 7 which turns ON / OFF the drive of the fan motor 9 provided in the inside is provided.

The conventional vacuum cleaner configured as described above, when the user turns on the switch 7 installed on the upper surface of the handle 4, the fan motor 9 is driven to the brush assembly 6, the multi-stage extension tube 5 and the flexible suction tube 3 By sucking the air through the dust or dirt on the surface to be cleaned is sucked into the dust collecting chamber 8 inside the cleaner body 1.

However, the conventional vacuum cleaner configured as described above performs cleaning while moving the surface to be cleaned according to the cleaning distance through the wheel of the cleaner main body 1, and thus the cleaner main body falls down during the cleaning operation of the staircase, and furthermore, it is used for cleaning the curtains or curtains. When cleaning a high place, such as the need to carry out the cleaning of the cleaner body there was a problem in use uncomfortable.

In order to solve the above problems, conventionally, a backrest device for allowing a user to wear a vacuum cleaner on the back has been proposed. However, this backrest device is inconvenient to fix the vacuum cleaner to the backrest device before use as a separate device.

In order to solve this inconvenience, a method of using a shoulder strap has been devised as shown in FIG. 2. This method can be carried around the shoulder strap 20, just by inserting the shoulder strap fixture 30 to the support portion 40 of the cleaner body can be carried on the shoulder cleaning has been solved. However, this method has a problem in that the fitting structure is merely annular as shown in Figs. 3A and 3B, and it is easy to fall out during cleaning. That is, the projection 31 of the shoulder strap fixture 30 is inserted into the large hole portion 42 of the lower portion of the support portion 40, and then the force is applied to the large hole portion 42 and the small hole portion of the lower portion of the support portion 40 forcibly ( 41 is raised between the projections 43 formed between the small hole 41 at the upper end of the shoulder strap fixture 30 is fixed to the support 40 as shown in Figure 3b. However, since the cleaner body 1 is only hanging on the projection 31 of the shoulder strap fixture 30, the cleaner body 1 receives upward force and the projection portion 31 of the fixture has a large hole 42. If you go to the side, you may fall out. When the projections 31 of the fixture 30 are pulled out, the vacuum cleaner falls and keeps the user's foot off, or falls to the floor and is broken.

The present invention is to solve the conventional problems as described above, while the convenience of the work when cleaning the high places such as stairs, long farms and curtains, while the shoulder strap of the vacuum cleaner does not easily fall off the fixing strap of the vacuum cleaner during cleaning The purpose is to provide a fixed structure.
