As shown in fig. 10, an embodiment of the present utility model provides a pile 100 configured to support maintenance surface cleaning equipment including, for example, a hand-held floor scrubber, a floor mop, a dust collector, etc., the pile 100 including a tray portion 110 and a support portion 120, the support portion 120 being located at one side of the tray portion 110; the supporting part 120 comprises a shell 121, the shell 121 comprises an air inlet 1211 and an air outlet 1212, the air inlet 1211 is arranged on the back surface of the shell 121, and the air outlet 1212 is arranged on the lower side of the shell 121; the supporting part 120 further comprises a fan 122, the fan 122 is disposed in the housing 121, the fan 122 comprises an air inlet 1221 and an air outlet 1222, the fan 122 rotates to drive the air flow to flow, and the air flow flows out from the air outlet 1222 after entering from the air inlet 1221; the supporting portion 120 further includes a device to be cooled 123, the device to be cooled 123 includes a first device to be cooled 1231 (e.g., a first circuit board) and a second device to be cooled 1232 (e.g., a second circuit board), and a housing is disposed outside the first device to be cooled 1231 and the second device to be cooled 1232 to prevent dust or moisture from entering the housing, and the device to be cooled 123 is disposed on an airflow path between the air inlet 1211 of the housing 121 and the air inlet 1221 of the fan 122, and the airflow path takes away heat generated by the airflow along with the airflow flowing from the surface of the device to be cooled 123, as indicated by an arrow in fig. 10. The structure does not need to additionally add any heat dissipation structure, and directly utilizes the air flow entering the fan (the air flow is called cold air flow before entering the fan) to take away the heat of the device 123 to be cooled, so that the dual purposes of air inlet and heat dissipation are achieved.

In some embodiments, as shown in fig. 11, the airflow path includes a first gap 1233 between the first device to be heat-dissipated 1231 and the second device to be heat-dissipated 1232. In some embodiments, the airflow path includes a second gap 1234 between the device surface to be heat dissipated and the back of the housing. In some embodiments, the airflow path includes a side gap and/or a bottom gap 1235 of the first device to be heat dissipated. That is, the cold air flow entering from the air inlet 1221 may flow through any one or more of the first gap 1233, the second gap 1234, the gaps on both sides of the first device to be cooled 1231, and the bottom gap 1235, and the number of the flowing gaps is different according to the fan power, and the gaps all surround the first device to be cooled 1231, so that the cooling effect on the first device to be cooled 1231 is optimal.

In some embodiments, as shown in fig. 12, the geometric center of the air inlet 1211 is lower than the lower edge of the first gap 1233, and in this embodiment, the geometric center of the air inlet 1211 is circular, and if it is rectangular, the geometric center is the intersection of the diagonals. The geometric center of the air inlet 1211 is lower than the lower edge of the first gap 1233, so that no matter how large the air inlet 1211 is, the air flow can be ensured to be directly blown to the surface of the first heat dissipation device 1231, then the air flow is dispersed around the surface of the first heat dissipation device 1231, and flows to any one or more of the first gap 1233, the second gap 1234, the two side gaps of the first heat dissipation device to be dissipated and the bottom gap 1235 along the surface of the first heat dissipation device 1231, thereby ensuring the heat dissipation effect of the first heat dissipation device to be dissipated 1231.

In some embodiments, as shown in fig. 13, the pile 100 further includes a heating device 124, where the heating device 124 is, for example, an electric heating wire, and the heating device 124 is disposed on the air outlet side of the blower 122, and the air in the air flow path flows out through the air outlet of the blower 122, and flows out from the air outlet 1212 of the housing after being heated by the heating device 124. The cold air flow enters the heating device 124 after passing through the fan and is heated to become hot air flow, and the hot air flow is blown to the rolling brush through the hot air channel 125, so that the rolling brush is dried, as shown in fig. 10. In this embodiment, the front-stage air flow before the air flow for drying in the pile 100 is heated is used as the cooling air flow, the cooling air flow is used for radiating the device to be radiated before being heated, the radiating function is completed, the cooling air flow is primarily heated after passing through the device to be radiated, then is heated into the drying air flow through the heating device 124, the air flow of the drying fan is reused for radiating in the cooling process, no additional radiating fan is needed, and the power consumption of the heating device 124 is saved. In some embodiments, the application scenario has higher tolerance on the duration required by drying, and can accept longer drying time, and after the cooling airflow is primarily heated by the device to be cooled, the heating device is not arranged for further heating, and the cooling airflow is directly used for drying the rolling brush. Similarly, the air path of the fan used by other functions in the device can be reused, for example, by multiplexing the working air flow of the sewage recovery fan to dissipate heat of the device to be cooled.

The pile provided by the embodiment of the utility model is provided with the fan, air flow enters from the air inlet of the fan, and in the process of flowing to the air outlet, the air flow can pass through the internal gap of the shell, particularly when the air flow flows through the gap between the two main boards, the heat emitted by the two main boards during working can be taken away by the way, and the good working environment of the main boards is ensured.
