A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0033] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0034] In the prior art, a sweeping robot includes a base station and a robot body. The base station includes an outer shell and a drying fan. The air inlet of the drying fan is arranged toward the outer shell of the base station. Since the distance between the drying fan and the outer shell is small, when the drying fan is working, the base station as a whole will howl.

[0035] For this reason, Figure 1-4 As shown, a base station is provided in an embodiment of the utility model to solve the above technical problems.

[0036] Specifically, Figure 1 and Figure 2 As shown, the base station includes a shell 1, a drying fan 2 and a fan bracket 3, the shell 1 forms an internal space, the drying fan 2 is arranged in the internal space and is arranged away from the inner side wall of the shell 1, the fan bracket 3 is arranged in the internal space, the drying fan 2 is fixedly installed on the fan bracket 3, the air inlet of the drying fan 2 is arranged toward the bracket body 31 of the fan bracket 3, and the distance between the air inlet of the drying fan 2 and the bracket body 31 is greater than or equal to the first preset distance.

[0037] Since the air inlet of the drying fan 2 is arranged away from the inner wall of the shell 1, and the distance between the air inlet of the drying fan 2 and the bracket body 31 of the fan bracket 3 is greater than or equal to the first preset distance, such a limitation can ensure that a certain distance is maintained between the air inlet of the drying fan 2 and the bracket body 31, and the howling problem caused by the close distance between the air inlet and the bracket body 31 can be avoided. Since the air inlet of the drying fan 2 is arranged toward the bracket body 31, compared with changing the distance between the air inlet of the drying fan 2 and the inner wall of the shell 1, the overall volume of the base station will not be significantly increased. In addition, it can also avoid the reduction of air intake due to the close distance between the air inlet of the drying fan 2 and the bracket body 31, thereby improving the drying effect.

[0038] In some embodiments, Figure 2-Figure 4 As shown, the base station further includes a control board 4, which is arranged on the side of the bracket body 31 facing the drying fan 2, and the side of the control board 4 provided with components is arranged facing the drying fan 2. When the drying fan 2 is working, air flows from the control board 4 toward the side of the drying fan 2. Since the air temperature is lower than the temperature of the components of the control board 4, the low-temperature air contacts the control board 4 and can take away the heat of the control board 4, thereby achieving the purpose of air cooling the control board 4. In addition, the control board 4 is arranged on the bracket body 31, which can also reduce the volume of the base station.

[0039] In some embodiments, the distance between the control panel 4 and the drying fan 2 is greater than or equal to the second preset distance, and the first preset distance is greater than the second preset distance. Such a limitation can prevent the problem of howling caused by the close distance between the control panel 4 and the drying fan 2, and can also avoid the situation where the gap between the control panel 4 and the drying fan 2 is small and the air volume is small.

[0040] For example, the second preset distance is h, and the second preset distance h≥10mm. It can be understood that the distance between the control board 4 and the air inlet of the drying fan 2 is greater than or equal to 10mm, and such a setting can avoid the whistling problem caused by a close distance and the problem of small amount. For example, the second preset distance h can be selected as 15mm, which is not specifically limited in this embodiment.

[0041] In some embodiments, the control panel 4 is arranged opposite to the drying fan 2, wherein the positive projection of the air inlet on the side of the control panel 4 facing the drying fan 2 at least partially overlaps with the control panel 4, so that the air can flow through all parts of the control panel 4 to take away the heat of the control panel 4. As a preferred embodiment, the positive projection of the air inlet on the side of the control panel 4 facing the drying fan 2 completely overlaps with the control panel 4, that is, the control panel 4 is arranged opposite to the air inlet of the drying fan 2. In addition, the temperature of the control panel 4 increases after the air cools down, so the heating temperature of the heating element in the drying fan 2 will also be reduced accordingly, thereby achieving the purpose of saving electricity.

[0042] In some embodiments, the base station further includes a rechargeable light board, and the control board 4 and the rechargeable light board are an integrated structure. This arrangement can realize that the rechargeable light board is also installed after the control board 4 is installed, saving assembly time, improving assembly efficiency, and reducing assembly difficulty.

[0043] In some embodiments, continue to refer to Figure 2-Figure 4 The fan bracket 3 further includes a connecting column 32, and the two ends of the connecting column 32 are respectively fixedly connected to the bracket body 31 and the drying fan 2. The setting of the connecting column 32 can provide a connection support for the drying fan 2, and can achieve the purpose of separating the drying fan 2 and the bracket body 31. For example, the connecting column 32 is fixedly connected to the drying fan 2 by a fastener, and the fastener passes through the drying fan 2 and is connected to the connecting column 32, so as to achieve the purpose of fixedly connecting the connecting column 32 to the drying fan 2. More specifically, the fastener is a screw.

[0044] In some embodiments, since the drying fan 2 is relatively large, multiple connecting columns 32 are required to achieve fixed connection. However, the arrangement of multiple connecting columns 32 may cause interference between some connecting columns 32 and the control board 4. Figure 3 and Figure 4 As shown, the control board 4 is provided with at least one avoidance hole 41 through which the connecting column 32 can pass. The number of the avoidance holes 41 is determined according to the number of the connecting columns 32 interfering with the control board 4, and is not specifically limited here. For example, as shown in the figure, the number of the avoidance hole 41 is one.

[0045] In some embodiments, Figure 4 As shown, the outer periphery of the connecting column 32 that does not interfere with the control board 4 is provided with a reinforcing rib 33. The provision of the reinforcing rib 33 can ensure the strength of the connecting column 32, and the connecting column 32 that interferes with the control board 4 is not provided with the reinforcing rib 33, so that the diameter of the avoidance hole 41 can be as small as possible, thereby avoiding occupying a large area of ​​the control board 4 and affecting the actual use of the control board 4.

[0046] In some embodiments, Figure 3As shown, the drying fan 2 includes a fan body 21 and an air outlet channel 22. The air outlet channel 22 is bent, and the air inlet of the air outlet channel 22 is connected to the air outlet of the fan body 21. The air outlet 222 of the air outlet channel 22 faces the fan bracket 3 and is located below the fan bracket 3. It should be noted that the air outlet 222 of the air outlet channel is the air outlet of the drying fan 2. The fan body 21 has a connecting ear 212, and the two connecting ears 212 are arranged at two diagonal corners of the fan body 21. Such an arrangement can ensure that the fan body 21 is fixed. Connecting blocks 221 are arranged on both sides of the air outlet channel 22. The connecting blocks 221 are arranged on two opposite side walls of the air outlet channel 22. Each connecting block 221 is connected to a connecting column 32, so that both sides of the air outlet channel 22 can be stably supported to avoid vibration during operation.

[0047] The utility model also provides a sweeping machine, including a robot body and a base station provided by an embodiment of the utility model, wherein the housing 1 of the base station has a passage opening, and the robot body enters and exits the internal space of the housing 1 through the passage opening. Since the base station includes a drying fan 2 and a fan bracket 3, the air inlet of the drying fan 2 is arranged away from the inner side wall of the housing 1, and the distance between the air inlet of the drying fan 2 and the bracket body 31 of the fan bracket 3 is greater than or equal to the first preset distance, such a limitation can ensure that a certain distance is maintained between the air inlet of the drying fan 2 and the bracket body 31, and the whistling problem caused by the close distance between the air inlet and the bracket body 31 can be avoided. Since the air inlet of the drying fan 2 is arranged toward the bracket body 31, compared with changing the distance between the air inlet of the drying fan 2 and the inner side wall of the housing 1, the overall volume of the base station will not be significantly increased. In addition, it can also avoid the air inlet of the drying fan 2 and the bracket body 31. The air intake is reduced due to the close distance between the air inlet and the bracket body 31, thereby improving the drying effect.

[0048] Since the above-mentioned base station is included, the sweeping machine of the embodiment of the utility model has all the advantages and beneficial effects of the above-mentioned embodiments, which will not be described in detail here.

[0049] In addition, the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention.
