Meanwhile, the air inlet of the first air duct 32 is deviated to one side along with the position of the dirt collecting box 20, that is, the distances between the two ends of the rolling brush 12 and the air inlet of the first air duct 32 are different.
Further, in order to reduce the dead angle of cleaning and sufficiently clean the ground garbage, the air duct assembly 30 further includes a fourth air duct 35 and a fifth air duct 36, air inlets of the fourth air duct 35 and the fifth air duct 36 are both connected to an air outlet of the third air duct 34, air outlets of the fourth air duct 35 and the fifth air duct 36 are respectively communicated with the cleaning cavity 11, which is equivalent to that the air flow flowing out of the third air duct 34 is divided into two parts, and the two parts respectively flow into the cleaning cavity 11 from the fourth air duct 35 and the fifth air duct 36. It is understood that a part of the air flow generated by the fan 31 flows into the cleaning chamber 11 through the third air duct 34, and another part of the air flow is discharged out of the automatic cleaning apparatus 100. Of course, the air flow passing through the fan 31 may also be entirely merged into the cleaning chamber 11, thereby improving the wind efficiency.
It should be noted that the air outlet of the third air duct 34 is located above the roller brush assembly 10, the fourth air duct 35 extends from the air outlet of the third air duct 34 to one end of the roller brush 12, and the fifth air duct 36 passes through the gap between the first air duct 32 and the housing 13, so that the fifth air duct 36 is partially disposed between the first air duct 32 and the cleaning cavity 11 and is communicated with the other end of the roller brush 12.
In the above embodiment, the air outlet of the fourth air duct 35 and the air outlet of the fifth air duct 36 are respectively located at two ends of the rolling brush 12, which is equivalent to that the first air duct 32 is disposed between the fourth air duct 35 and the fifth air duct 36, and the air outlet of the fourth air duct 35, the air inlet of the first air duct 32 and the air outlet of the fifth air duct 36 are all located on the same straight line. Of course, in other embodiments of the present invention, the fourth air duct 35 and the fifth air duct 36 may also be partially inclined toward the first air duct 32 to improve the utilization rate of the air flow.
In particular, the distance between the air outlet of the fourth air duct 35 and the air outlet of the fifth air duct 36 is equal to the length of the roller brush 12, so that the fourth air duct 35 and the fifth air duct 36 can clean the dead angle farthest from the first air duct 32. It should be noted that the "length" herein may be a distance between a center line of the fourth air duct 35 and a center line of the fifth air duct 36, or a distance between two side walls of the fourth air duct 35 and the fifth air duct 36, which are farthest from each other, and may be specifically set as required. When only one rolling brush 12 is provided, the air outlet of the fourth air duct 35 and the air outlet of the fifth air duct 36 both face the front side of the advancing direction of the rolling brush 12. When the number of the rolling brushes 12 is two, the air outlet of the fourth air duct 35 and the air outlet of the fifth air duct 36 are both disposed toward between the two rolling brushes 12, and certainly not limited to be disposed toward the front side of the advancing direction of the rolling brushes 12, and may be specifically disposed as required, and no limitation is made herein.
In order to make the fourth air duct 35 and the fifth air duct 36 more effectively blow up the garbage on the ground, the cross-sectional area of the third air duct 34 is larger than the cross-sectional area of the fourth air duct 35, and is also larger than the cross-sectional area of the fifth air duct 36. Since the flow rate of the third air duct 34 is equal to the sum of the flow rates of the fourth air duct 35 and the fifth air duct 36, the air flow velocity can be enhanced when the cross-sectional areas of the fourth air duct 35 and the fifth air duct 36 are reduced.
In the present invention, the third air duct 34 is disposed close to the fourth air duct 35, and the dirt collecting box 20 is disposed close to the fifth air duct 36, so that the first air duct 32 is closer to the fifth air duct 36, so that a distance between an air outlet of the fourth air duct 35 and an air inlet of the first air duct 32 is greater than a distance between an air outlet of the fifth air duct 36 and an air inlet of the first air duct 32, that is, a distance from an air flow flowing out of the fourth air duct 35 to flow back to the first air duct 32 is greater than a distance from an air flow flowing out of the fifth air duct 36 to flow back to the first air duct 32, and an escape degree of the air flow flowing back through the fourth air duct 35 is higher.
Further, the distance from the air outlet of the third air duct 34 to the air outlet of the fourth air duct 35 is smaller than the distance from the air outlet of the third air duct 34 to the air outlet of the fifth air duct 36, so as to enhance the airflow rate of the fourth air duct 35, and finally make the airflows flowing back at the two sides of the first air duct 32 substantially equal. Moreover, the heights of the air outlet of the fourth air duct 35 and the air outlet of the fifth air duct 36 in the vertical direction are higher than that of the air inlet of the first air duct 32, so that the air flow blows from a low position to a high position, an air gathering effect is formed, and a suction effect is improved.
In summary, the air duct is set to be of a circulating type, so that the airflow backflow can be used to enable the garbage at the two ends of the rolling brush 12 to be more easily absorbed, the cleaning effect on the ground is enhanced, the secondary pollution caused by the exhaust of the airflow flowing out of the dirt collecting box 20 is reduced, and the use experience of a user is enhanced.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
