That is, the wind passage part 119 is provided in a number of the upper and lower fixing parts 118a and 118b of the shoulder strap to cool the heat by removing the wind or blowing the wind through the fan. At this time, the fan and the wind passage part 119 can communicate with each other through a hose or the like.

Moreover, wheel installation holes H are provided at the lower ends of both sides of the main body 110 so that wheels (not shown in the drawings) can be respectively installed.

On the other hand, although not shown in the drawing, at least one compartment is formed inside the main body 110 to increase the amount of air exhaust.

The cover 120 opens and closes the opened upper end of the main body 110, a suction port 122 for inhaling dust is formed at the front end of the upper surface, and a handle 124 is provided at the rear end of the upper surface.

Moreover, the hose 12 to which the suction unit 10 is connected is detached from the suction port 122 so as to suck dust.

Further, the locking portions 126 bent in a "U" shape are fixed to both side walls of the cover 120 so that the binding hooks 116 of the main body 110 can be bound or released.

The shoulder strap 130 is fixed to the upper and lower fixing portions 118a and 118b of the shoulder strap provided on the rear surface of the main body 110, and is provided so that the user can fix the shoulder and waist portions.

At this time, the shoulder strap 130 is composed of a portion worn on the shoulder and a portion capable of connecting both ends to the waist through a male and female buckle, and is detachably provided on the upper and lower fixing portions 118a and 118b of the shoulder strap.

Further, referring to FIG. 6, a male buckle 132 is additionally connected to a portion of the shoulder strap 130 surrounding the waist, so that the electric wire switch unit 160 having an arm buckle structure can be coupled.

The primary filter unit 140 is detachably provided in the dust suction inlet 122 of the cover 120 so that dust sucked through the inlet 122 is primarily filtered.

To this end, the primary filter unit 140 is provided with a connection bracket 142 to be connected to the suction port 122 on the upper surface, and the opened lower end is opened and closed by the sealing part 146 of a sliding method.

That is, when dust or the like flows into the primary filter unit 140, the lower end is opened for removal, and the opened lower end is sealed by a sealing portion 146 formed with a groove in the longitudinal direction on the upper surface.

On the other hand, the outlet 140a, which is the lower end of the primary filter unit 140, is filled with a reinforcing bar 144 therein so as to be sealed by the sealing unit 146 (see FIG. 5).

The reinforcing bar 144 is composed of a front and rear portion and a side portion that can be folded at opposite ends of the front and rear portions, and the side portion is provided to be rotatable by a hinge shaft while the side portion is provided at a set angle. A torsion spring (S) is installed on the hinge shaft to provide an elastic force so that the side portion can always open. At this time, one end and the other end of the torsion spring (S) are supported by the support protrusions (145a, 145b) on the side of the reinforcing bar (144), respectively. As the exit (140a) is opened. In this way, since the outlet 140a is opened, it is easy to discharge foreign substances such as dust.

The secondary filter unit 150 is provided to surround the primary filter unit 140 to perform secondary filtering, and the opened inlet is coupled to the bottom surface of the cover 120.

The electric wire switch unit 160 is detachably provided on the waist portion of the shoulder strap 130 so that the front end thereof is electrically connected to the electric wire switch unit connection port 114d to enable control.

In addition, a plug is installed at the rear end of the electric wire switch unit 160 to apply power to the cleaner.

That is, the electric wire switch unit 160 is difficult to manipulate the control switch 114a while the user wears the backpack type vacuum cleaner 100 on the shoulder, so to solve this problem, the power ON/OFF and the control switch 114a It is possible to select the mode of.

As described above, the operation process of the backpack type vacuum cleaner 100 of the present invention will be described as follows.

First, the shoulder strap 130 is fixed to the upper and lower fixing portions 118a and 118b of the shoulder strap provided on the rear surface of the main body 110, and the electric wire switch unit 160 is brought into contact with the electric wire switch connecting port 114d. Let it.

Next, the suction unit 10 is connected to the suction port 122 with a hose 12, and a male buckle connected to a portion of the buckle groove 164 of the electric wire switch unit 160 and the shoulder strap 130 surrounding the waist ( After binding 132) to each other, a vacuum cleaner is worn on the user's shoulder through the shoulder strap 130.

Next, the user manipulates the electric wire switch unit 160 located at the portion of the shoulder strap 130 that surrounds the waist, and cleans conveniently while putting the suction unit 10 at the position to be cleaned. At this time, the dust is sucked through the suction port 122 formed in the cover 120 through the suction unit 10 and the hose 12, and then dust through the primary filter unit 140 and the secondary filter unit 150. After the is removed, the wind from which the dust has been removed is discharged through the discharge port 112.

Next, when cleaning is complete, the binding hook 116 installed at the top of both side walls of the main body 110 is operated to separate it from the locking portions 126 installed at the bottom of both side walls of the cover 120, and then the cover 120 is removed. Open.

Next, after separating the secondary filter unit 150 by pulling it from the ceiling surface of the cover 120, the primary filter unit 140 is rotated to separate it.

Next, the dust filtered by the primary filter unit 140 is separated by sliding the sealing unit 146 at the outlet 140a of the primary filter unit 140 and then removed. After removal, the outlet 140a Fix the sealing part 146 to.

Next, dust remaining in the secondary filter unit 150 is removed, and then rotated to the inlet 122 of the cover 120 to fix the primary filter unit 140 and wrap the primary filter unit 140 The secondary filter unit 150 is coupled to the lower portion of the cover 120 so as to be possible.

Next, by operating the binding hook 116 in a state where the cover 120 is seated on the upper portion of the body portion 110, the cover 120 is bound to the locking portion 126 of the cover 120.

On the other hand, if the backpack type vacuum cleaner 100 of the present invention is to be used in a state that is placed on the floor like a general vacuum cleaner, the body part after removing the shoulder strap 130 from the upper and lower fixing parts 118a and 118b of the shoulder strap Wheels (not shown in the drawings) are mounted in the wheel installation holes H formed at the bottom of both side walls of 110.

Embodiments of the present invention have been described above with reference to the accompanying drawings, but those of ordinary skill in the art to which the present invention pertains can be implemented in other specific forms without changing the technical spirit or essential features. You will be able to understand. Therefore, it should be understood that the embodiments described above are illustrative in all respects and are not limiting.
