Referring to fig. 1, the cleaning robot 100 includes a robot body 110, and a blower 120 disposed in the robot body 110, wherein the blower 120 includes an air inlet 121 and an air outlet 122. The air is sucked from the outside by the air inlet 121 of the fan 120 to form an air flow flowing from the outside to the inside of the cleaning robot 100, so that the external garbage is sucked into the cleaning robot to realize a cleaning function, and meanwhile, the fan 120 exhausts air to the outside through the air outlet 122 to realize air flow circulation.

Referring to fig. 1 and 2, the cleaning robot 100 further includes a wind power generator 130, the wind power generator 130 is disposed at the air outlet 122, and is capable of generating power by using wind energy of the airflow discharged from the air outlet 122, the airflow discharged from the air outlet 122 contains a large amount of air kinetic energy, and the airflow discharged from the air outlet 122 is used for generating power by using wind energy, so as to recycle the wind energy. The wind power generation device 130 is connected to the power supply assembly 140 of the cleaning robot 100, so that the electric power generated by the wind power generation device 130 is transmitted to the power supply assembly 140 to supply power to the cleaning robot 100, thereby prolonging the working time of the robot. As shown in fig. 1, the wind turbine generator 130 and the power module 140 are connected by a power line 141. The power supply module 140 may be a rechargeable battery pack, so that the rechargeable battery pack is charged by the electric energy generated by the wind power generation device 130 when the cleaning robot 100 operates, and an additional device for recovering the electric energy is not required to be provided to recover the electric energy generated by the wind power generation device 130, that is, the electric energy generated by the wind power generation device 130 is directly consumed by the existing power supply of the cleaning robot 100, thereby simplifying the structure and saving the design cost.

In specific implementation, a dust suction port is formed in the bottom of the shell 111 of the robot main body 110, a dust box is arranged in the robot main body 110, the dust box is used for containing garbage sucked by the cleaning robot 100, the dust box is communicated with the dust suction port through a dust suction channel, the garbage on the ground enters the dust suction channel from the dust suction port, and finally the garbage is collected in the dust box to realize dust suction. The air inlet 121 of the fan 120 is communicated with the dust suction channel, so that dust suction airflow is formed in the dust suction channel. It should be noted that the air inlet 121 is generally provided with a filter, so that garbage can be prevented from entering the fan 120 from the air inlet 121, and the fan 120 can be prevented from being damaged or being discharged from the air outlet 122 by the fan 120; specifically, the filter element can be porous medium such as HEPA and composite filter screen.

An air outlet is formed in the outer shell 111 of the robot body 110, and the air outlet 122 is communicated with the air outlet through an air exhaust channel, so that air exhausted from the air outlet flows through the air exhaust channel and is exhausted to the outside from the air outlet in the outer shell 111, and air flow circulation during operation of the fan 120 is achieved. In the utility model, the wind power generation device 130 is arranged in the exhaust channel, the exhaust channel is arranged to enable the airflow at the air outlet 122 to be more converged rather than dispersed airflow, and the wind power generation device 130 is arranged in the exhaust channel where the airflow is converged, so that wind energy can be fully utilized, and the maximum wind energy recycling is realized.

In one embodiment, referring to fig. 2, the wind power generation device 130 includes a wind power generator 131 and an impeller 132. Specifically, the wind power generator 131 may be a permanent magnet dc generator. Referring to fig. 1 and 2, the wind power generator 131 is disposed on the robot main body 110, and the wind power generator 131 and the robot main body 110 may be fixedly connected by a fastening member such as a screw, so as to ensure a connection strength and a stability of the wind power generator 131 during operation. The impeller 132 is connected with an input shaft of the wind power generator 131, so that the impeller 132 can rotate with the wind power generator 131 to generate power. The impeller 132 is located in front of the air outlet 122 of the fan 120, so that the air outlet 122 of the fan 120 blows air towards the impeller 132, the air flow pushes the impeller 132 to rotate, and the impeller 132 drives the wind driven generator 131 to rotate.

In one embodiment, the fan 120 is provided with an air outlet 123, an end opening of the air outlet 123 forms the air outlet 122, and an end of the air outlet 123 is tapered. So set up to make air outlet 122 department exhaust gas more assemble, make the air current stronger, can promote the more quick rotation of impeller 132, promote wind energy utilization and generating efficiency.

It should be noted that the number of blades on the impeller 132 is too large, which is disadvantageous for balance and high in cost; the number of blades is too small, so that the power generation efficiency is influenced; preferably an odd number, typically 3 to 9, preferably 3 or 5, may be used. Of course, other numbers are possible and are not intended to be limiting.

Referring to fig. 2, the impeller 132 rotates about the rotation axis 101, and the rotation axis 101 is parallel to the air outlet 122. The rotation axis 101 and the air outlet 122 are arranged in parallel, and an included angle is formed between the rotation axis 101 and the air outlet 122, so that the rotation speed of the impeller 132 is faster, and the utilization rate of wind energy is improved.

Further, referring to fig. 2 and 3, the rotation axis 101 is located on one side of the air outlet 122 along the width direction D of the air outlet 122. As shown in fig. 2, the length direction L and the width direction D of the air outlet 122 are perpendicular to each other, and the rotation axis 101 is parallel to the length direction L of the air outlet 122, and with reference to fig. 2 and 3, in the width direction D of the air outlet 122, the rotation axis 101 is located on one side of the air outlet 122 along the width direction D thereof, which is shown in fig. 3, that is, the center point O of the impeller 132 is located below the bottom end of the air outlet 122. Of course, the center point O of the impeller 132 may be located above the uppermost end of the air outlet 122. The rotation axis 101 is arranged on one side of the air outlet 122 in the width direction D, rather than arranging the rotation axis 101 in the width range of the air outlet 122, so that the airflow discharged from the air outlet 122 is only blown to the blades on one side of the impeller 132, the airflow does not simultaneously act on the blades on two sides of the impeller 132, the phenomenon that the forces acting on the blades on different sides are mutually offset does not occur, the rotation speed of the impeller 132 is increased, and the power generation efficiency is improved.

Referring to fig. 2, the length of the blades of the impeller 132 is greater than or equal to the length of the air outlet 122. Therefore, the blades can completely cover the two ends of the air outlet 122 along the length direction L of the air outlet, air flows exhausted from the air outlet 122 are fully utilized as far as possible, and the utilization rate of wind energy is improved.
