Problems solved by technology
Although the structure is not complicated, such a dust collection accessory is cumbersome to use. After putting on the garbage bag, the user needs to pass the flexible rope through the bottom of the cover, and then pull the two ends of the rope around the outer peripheral surface of the cover to tighten it , and finally tie the rope
In addition, the flexibility of the rope makes the fixing of the garbage bag and the cover not firm enough. When a certain amount of air accumulates in the garbage bag, the garbage bag may break through the shackles of the flexible rope and disengage from the cover.

Embodiment Construction
[0047] The present disclosure discloses a blower 100 and a dust collection accessory 200 used in conjunction with the blower 100 .
[0048] seefigure 1 As shown, the blower 100 includes a main body casing 1 provided with an air inlet 12 and an air outlet 13, an operating handle 11 is provided on the main body casing 1, a switch 111 is provided on the operating handle 11, and a A fan (not shown in the figure) and a motor (not shown in the figure) for driving the fan to rotate, in this embodiment, the fan is arranged between the air inlet 12 and the air outlet 13, that is, the impeller surface of the fan and the air inlet The direction of the air outlet 12 is the same, and the side edge of the fan is in the same direction as the air outlet 13 , in other words, the orientation of the air inlet 12 and the air outlet 13 is almost perpendicular. In this way, after the switch 111 is triggered, the motor starts to drive the fan to rotate, and when the centrifugal fan rotates, the air ...

The invention relates to a dust collecting accessory which can be connected to a dust outlet of a suction blower and is used for leading fallen leaves discharged through the dust outlet into a garbage bag. The dust collecting accessory comprises a support cover and a clamping piece, wherein one end of the support cover is connected to the dust outlet in a ventilating manner, and the other end of the support cover is provided with a rigid peripheral surface to open an opening of the garbage bag; the clamping piece is a rigid piece, the inner surface of the clamping piece is matched with the peripheral surface of the support cover in shape, the clamping piece can perform releasing or clamping selectively; in the releasing state, the inner surface of the clamping piece deviates from the support cover; in the clamping state, the clamping piece is arranged on the peripheral surface of the support cover in a sleeving manner, and thus the garbage bag is clamped. The inner surface of the rigid clamping piece is matched with the peripheral surface of the support cover in shape, therefore the clamping piece is fixed around the support cover through simple operation by a user when the garbage bag is clamped, and locking is more reliable. Compared with the prior art, significant progress is made. The invention also relates to the suction blower being provided with the dust collecting accessory.
Description
technical field [0001] The present invention relates to a dust collecting accessory, and also relates to a blower equipped with the dust collecting accessory. Background technique [0002] Existing blower mainly comprises the main body housing that is provided with air inlet and dust outlet, is located at the fan in main body housing, and is used to drive the motor that fan rotates, and fan rotates at high speed under the drive of motor, makes main body casing The air pressure in the body drops suddenly, thus forming a directional airflow that enters from the air inlet and flows out from the dust outlet. The blower generally connects the suction pipe to the air inlet, and connects the dust bag to the dust outlet, so as to use the directional airflow to suck and collect the fallen leaves. Dust bags are usually made of woven fabric and can be recycled. But the fly in the ointment is that the volume of the dust bag is limited. If there are many fallen leaves, the user needs t...
