Detailed Description

The technical scheme of the patent is further described in detail below with reference to the specific embodiments.

As shown in fig. 1 and 2, a backpack type dust collector of the present utility model includes a backpack device and a dust collector main body mounted on the backpack device, the backpack device includes a back plate 10 and two straps 12 disposed on the back plate, the dust collector main body includes a box 14, a dust collection hose (not shown in the drawing) and a collection bag (not shown in the drawing), a fan (not shown in the drawing) is disposed in the box, a storage battery (not shown in the drawing) is disposed on the box, an air inlet pipe 16 and an air outlet pipe 18 are disposed on the box, the storage battery is used for driving the fan, the fan is not required to be powered by electric wires, the air inlet pipe 16 and the air outlet pipe 18 are more convenient to be matched with the dust collection hose, and an annular groove 20 is disposed on the peripheral wall of the air outlet pipe 18.

In the second embodiment, as shown in fig. 3 to 8, the difference from the first embodiment is that the case 14 is connected to the back plate 10 through two connecting rods, one end of each connecting rod is hinged to the case 14, the other end of each connecting rod is disposed on the back plate 10, each connecting rod is composed of two mutually hinged sub-rods 32, a first boss 34 is disposed at one end of each sub-rod on the back plate 10, a second boss 36 is disposed at a hinged position of each sub-rod 32, two sliding grooves 22 and a plurality of chute 24 communicating with the sliding grooves 22 are disposed on the back plate 10 along a height direction thereof, a hinge plate 26 is hinged at a communicating position of each sliding groove 22 and each chute 24, a torsion spring (not shown in the drawing) is disposed between each hinge plate 26 and the back plate 10, a protrusion 28 for restricting the hinge plate 26 from rotating in each sliding groove 22 is disposed on the back plate 10, an opening 30 for the second boss 36 to enter each sliding groove 22 is disposed on the back plate 10, and a universal wheel 38 is disposed at a bottom of the case 14.

In the first embodiment, when in use, the collecting bag is sleeved on the air outlet pipe 16, then the collecting bag is hooped by the clamp at the annular groove 20, then the dust collection hose is installed on the air inlet pipe 18, the dust collector is backed up by the back plate 10 and the back belt 12, the dust collection hose is held by hand to be aligned with the bottom surface to clean dust and scraps, the dust collection hose can be used in places with smaller space, when the ground is slippery or scraps which are difficult to clean are in corners, the dust collection hose and the collecting bag can be detached, the dust collection hose is installed on the air outlet pipe 16, the other end of the dust collection hose faces the ground, and the evaporation of the ground moisture and the cleaning of the scraps in the corners are accelerated by a blowing mode.
