The purpose of setting the guide wall 14b is to change the flow direction of the air so that the air flows into the inside of the agitator. In actual use, the guide wall 14b has a certain hindering effect on the smooth flow of air, although the guide wall is set for the rotation of the agitator. However, because the flow direction of the air changes sharply through the guide wall 14b, the flow energy of the air transmitted to the agitator is reduced, so the desired effect cannot actually be achieved.
In addition, setting the guide wall 14b makes the structure of the suction nozzle itself complicated, which is not conducive to its injection molding.

Embodiment Construction
[0014] Hereinafter, the present invention will be further described in detail based on the embodiments shown in the drawings.
[0015] refer to figure 2 As shown, it is a schematic cross-sectional view of the partial structure of the cover 20 of the suction nozzle of the vacuum cleaner of the present invention. The inside of the cover 20 is provided with a vent hole 22, and the air flow (air flow) is sucked in through the vent hole 22 to make the built-in agitator perform rotate.
[0016] The inner lower upper surface 24 of the vent hole 22 of the present invention is inclined backward, and the inclined inner lower upper surface 24 is formed when the cover 20 with the vent hole 24 is injection-molded. A stirrer (omitted among the figures) is installed at the rear of the air hole 22 . The same as the use of existing products, the agitator is rotated by the airflow sucked by the vent hole 22, but, because the upper surface 24 of the inner lower part of the vent hole 22 is inc...

The invention provides a suction nozzle of the vacuum cleaner. It comprises a main body, inside of which rotatable agitator is set and forms to the bottom, a cover cap, covering the main body bottom. On the anterior part of the cover cap, air hole for sucking outside air is installed, the lower part of the air hold top forms a bevel slants to rear lower part, the bevel faces up to the rear agitator, and the structure of which is simple and reasonable. It makes the agitator rotates more effectively and smoothly, in further improves the sweeping effect.
Description
1. Technical field [0001] The invention relates to purification equipment, in particular to a suction nozzle of a vacuum cleaner in which a stirrer that can be rotated by air flow is installed inside the suction nozzle body to suck air more smoothly and make the stirrer rotate more easily. 2. Background technology [0002] refer to figure 1 As shown, the suction nozzle 10 of the existing vacuum cleaner includes a body 12 and a cover 14, and a rotatable agitator is arranged inside. The agitator 16 is located inside the suction nozzle and is rotatable. It is rotated by the sucked air, so the dust on the ground can be sucked by the brush-shaped part installed on the outer peripheral surface. As an example, the vacuum cleaner nozzle 10 equipped with the above-mentioned agitator 16 is used to separate and suck foreign matter such as dust on bedding or carpets. In addition, the bottom surface of the main body 12 of the suction nozzle 10 is provided with a ventilation hole 12a, t...
