[0055] This disclosure provides a cleaning system including a cleaning device and a base station. The cleaning device can be a handheld floor scrubber, a self-propelled cleaning robot, etc., used to clean the area to be cleaned. The cleaning device can cooperate with the base station for charging, cleaning, and drainage. Furthermore, the cleaning device and the base station are charged wirelessly. The cleaning device is equipped with a receiving component for wireless charging, and the base station is equipped with a transmitting component for wireless charging. The transmitting component is configured to cooperate with the receiving component after the cleaning device is docked with the base station, so as to wirelessly charge the cleaning device through the base station. The base station is equipped with a heat dissipation duct, which forms an air outlet on the base station. The airflow exiting the air outlet is configured to blow towards the mating area of the receiving component and the transmitting component.
[0056] The cleaning equipment and base station are charged wirelessly, replacing the direct metal-to-metal charging method. This avoids sparking issues during docking. The transmitting and receiving components can be designed to be waterproof, preventing water from the cleaning equipment from directly contacting the transmitting and receiving components used for charging, effectively reducing safety risks.
[0057] The transmitting and receiving components used for wireless charging generate heat during operation. By installing a heat dissipation duct inside the base station, the air outlet of the heat dissipation duct blows air towards the mating area of the receiving and transmitting components, which can dissipate heat and cool down the receiving and transmitting components, avoid overheating during charging, and further improve the safety of the cleaning system.
[0058] The technical solution disclosed herein will be described in detail below with reference to its specific structure.
[0059] In some embodiments of this disclosure, such as Figure 1 , Figure 2As shown, the cleaning system includes a cleaning device 1 and a base station 2. The cleaning device 1 is equipped with a receiving component 10, and the base station 2 is equipped with a transmitting component 20. The base station 2 can supply power to the transmitting component 20. When the transmitting component 20 cooperates with the receiving component 10, it can transmit electrical energy to the receiving component 10, and the electrical energy received by the receiving component 10 is supplied to the cleaning device 1. Wireless charging through the transmitting component 20 and the receiving component 10 is prior art that can be implemented by those skilled in the art, and the specific principles of the transmitting component 20 and the receiving component 10 will not be described in this disclosure.
[0060] After the cleaning device 1 is connected to the base station 2, the receiving component 10 and the transmitting component 20 work together. The base station 2 charges the cleaning device 1 through the transmitting component 20 and the receiving component 10. Specifically, the receiving component 10 is hidden inside the cleaning device 1, and the transmitting component 20 is hidden inside the base station 2, protecting both components from damage caused by water exposure. Figure 2 As shown, the transmitting component 20 and the receiving component 10 generate significant heat during charging, requiring timely heat dissipation. Therefore, a heat dissipation duct 21 is provided on the base station 2, forming an air outlet 210. Airflow from the heat dissipation duct 21 is discharged through the air outlet 210 and directed towards the mating area of the receiving component 10 and the transmitting component 20 to dissipate heat, reduce temperature, and improve safety. Specifically, a negative pressure can be generated within the heat dissipation duct 21 by a fan assembly. Ambient air enters through the air inlet of the heat dissipation duct 21, exits through the air outlet 210, and is directed towards the receiving component 10 and the transmitting component 20 for heat dissipation.
[0061] In some embodiments of this disclosure, such as Figure 1 As shown, the cleaning device 1 includes a body 11 and a floor brush assembly 12 connected to the lower end of the body. A receiving component 10 can be disposed at the bottom of the floor brush assembly 12. The base station 2 can be supported on a support surface such as the ground. When the cleaning device 1 is connected to the base station 2, the floor brush assembly 12 is located above the base station 1 and is configured to be supported by the base station 1. The transmitting component 20 on the base station 2 is located below the receiving component 10 at the bottom of the floor brush assembly 12.
[0062] In other embodiments of this disclosure, the receiving component 10 may also be disposed at other locations on the brush assembly 12, or it may be disposed on the body 11, and the transmitting component 20 may be disposed at a location corresponding to the receiving component 10. For example, the base station 2 includes a support portion for supporting the body 11 of the cleaning device 1, and the transmitting component 20 may be disposed on the side wall of the support portion for supporting the body 11, and the receiving component 10 may be disposed on the body 11 at a location corresponding to the transmitting component 20.
[0063] In one embodiment of this disclosure, such as Figure 2 , Figure 3 As shown, base station 2 includes a support surface 22 for supporting at least a portion of the cleaning device 1, and the support surface 22 is capable of supporting at least a portion of the cleaning device 1. Base station 2 also has an air outlet 23 protruding from the support surface 22, and the air outlet 210 of the heat dissipation duct 21 is disposed on the air outlet 23 and located on the side wall of the air outlet 23 facing the mating area of the receiving component 10 and the transmitting component 20. Specifically, the cleaning device 1 can be supported on the support surface 22, and the air outlet 23 protrudes upward from the support surface 22.
[0064] In one embodiment of this disclosure, such as Figure 3 As shown, the floor brush assembly 12 is equipped with a cleaning element 122 for cleaning the surface to be cleaned and drive wheels 123 for moving on the surface to be cleaned. The cleaning element 122 can be a roller brush, a mop, a sweeping brush, etc. There are two drive wheels 123, located on opposite sides of the rear of the floor brush assembly 12, i.e., on the left and right sides in the direction of movement. The cleaning element 122 can clean the surface to be cleaned under the guidance of the two drive wheels 123. When the floor brush assembly 12 is cleaning, the drive wheels 123 and the cleaning element 122 can jointly support the movement of the cleaning device 1 on the ground. The base station 2 is provided with two drive wheel grooves 200. When the cleaning device 1 is docked with the base station 2, the two drive wheels 123 are respectively housed in the corresponding drive wheel grooves 200.
[0065] The receiving component 10 is located at the rear of the bottom of the floor brush assembly 12, away from the cleaning element 122. At least a portion of the receiving component 10 is situated between the two drive wheels 123. Correspondingly, the transmitting component 20 is located at the rear of the bearing surface 22, with at least a portion of the transmitting component 20 situated between the two drive wheel grooves 200 on the bearing surface 22. This arrangement ensures that the wireless charging coil of the receiving component 10 is away from the cleaning element 122, allowing the cleaning element 122 to remain away from wastewater during floor cleaning or self-cleaning.
[0066] In one specific embodiment of this disclosure, such as Figure 2 , Figure 3 As shown, the air outlet 23 is positioned on the base station 2 near the mating area. The height of the air outlet 210 on the bearing surface 22 is such that the air outlet 210 corresponds to the position where the receiving component 10 is located on the cleaning device 1, so that the airflow blown out of the air outlet 210 carries away the heat from the receiving component 10. Since the transmitting component 20 and the receiving component 10 are close together when mating, the airflow blown out of the air outlet 210 can also pass through the transmitting component 20 and carry away some of the heat emitted by the transmitting component 20.
[0067] When the cleaning device 1 is used with the base station 2, the cleaning device 1 can be fitted together with the bearing surface 22, or a gap can be left between the cleaning device 1 and the bearing surface 22. In one specific embodiment of this disclosure, such as Figure 2 , Figure 3 As shown, the bottom position of the ground brush assembly 12 corresponding to the receiving assembly 10 has a gap 220 with the position on the bearing surface 22 corresponding to the transmitting assembly 20. Specifically, the ground brush assembly 12 of the cleaning device 1 can be supported on the bearing surface 22 at other positions besides the receiving assembly 10. For example, the cleaning device 1 can be supported on the bearing surface 22 of the base station 2 by rollers or auxiliary wheels. Since the cleaning device 1 is relatively heavy, the gap 220 prevents the transmitting assembly 20 and the receiving assembly 10 from bearing excessive pressure, thus reducing the risk of damage. Furthermore, the gap 220 facilitates airflow; the airflow from the exhaust port 210 of the heat dissipation duct 21 can enter the gap 220, simultaneously carrying away heat from the area surrounding the transmitting assembly 20 and the receiving assembly 10, improving heat dissipation.
[0068] In one specific embodiment of this disclosure, such as Figure 2 , Figure 4 As shown, the bottom of the cleaning device 1 is provided with a guide surface 121 adjacent to the receiving component 10. This guide surface 121 can be the rear sidewall of the floor brush component 12. When the cleaning device 1 is used for charging on the base station 2, the guide surface 121 extends from the gap 220 between the transmitting component 20 and the receiving component 10 towards the air outlet 210, and gradually slopes upward, extending above the air outlet 210 and cooperating with the top of the air outlet 23 to guide the airflow discharged from the air outlet 210. The airflow discharged from the air outlet 210 can flow along the guide surface 121 into the gap 220 between the transmitting component 20 and the receiving component 10 to dissipate heat from the transmitting component 20 and the receiving component 10, preventing the airflow from dissipating from the sidewall of the floor brush component 12 and affecting the heat dissipation effect on the transmitting component 20 and the receiving component 10. In the embodiments of this disclosure, the emitting component 20 is disposed below the bearing surface 22. The airflow discharged from the air outlet 210 blows across the bearing surface 22 at the position corresponding to the emitting component 20, thereby carrying away the heat transferred from the emitting component 20 to the bearing surface 22.
[0069] In one embodiment of this disclosure, such as Figure 2 , Figure 4As shown, base station 2 is equipped with a fan assembly 24, which creates a negative pressure in the heat dissipation duct 21 to allow external airflow to enter the duct 21 and be blown out through the air outlet 210, thus dissipating heat from the transmitting component 20 and the receiving component 10. Specifically, base station 2 is equipped with a fan cavity 250, and the fan assembly 24 is installed in the fan cavity 250. The heat dissipation duct 21 is configured to extend from the fan cavity 250 to the air outlet 210. The transmitting component 20 can be disposed in the heat dissipation duct 21, and the transmitting component 20 is directly cooled by the airflow in the heat dissipation duct 21.
[0070] Under the action of the fan assembly 24, airflow enters the heat dissipation duct 21 from the opening of the fan cavity 250, directly dissipating heat from the transmitting component 20, and then flows out from the air outlet 210 of the heat dissipation duct 21, blowing towards the mating area of the receiving component 10 and the transmitting component 20 for heat dissipation. In the field of wireless charging, the heat dissipated by the transmitting component 20 is higher than the heat emitted by the receiving component 10. Therefore, by directly placing the transmitting component 20 in the heat dissipation duct 21, the airflow flowing in the heat dissipation duct 21 can directly act on the transmitting component 20, greatly improving the heat dissipation effect of the transmitting component 20.
[0071] In one embodiment of this disclosure, such as Figure 2 , Figure 5 As shown, the transmitting assembly 20 includes a circuit board 201 and a transmitting coil 202. The transmitting coil 202 can be connected to the circuit board 201 by means of adhesive, snap-fit, or other methods, and the transmitting coil 202 is connected to the side of the circuit board 201 near the receiving assembly 10. For example, the transmitting coil 202 is glued to the top of the circuit board 201 with adhesive 203.
[0072] In one embodiment of this disclosure, such as Figure 2 , Figure 4 As shown, a mounting housing 25 is provided in the base station 2, and a heat dissipation duct 21 is formed between the mounting housing 25 and the inner wall of the base station 2. For example, the mounting housing 25 can be fixed inside the base station 2 by screws, and the edge of the mounting housing 25 can be sealed to the inner wall of the base station 2 by a sealing element. The mounting housing 25 can be detachably connected to the base station 2 to facilitate the assembly and disassembly of the transmitting component 20. The mounting housing 25 can be configured as a one-piece structure or a spliced structure. The heat dissipation duct 21 can be divided into two parts by the circuit board 201 of the transmitting component 20, including a first heat dissipation duct 211 located below the circuit board 201 and a second heat dissipation duct 212 located above the circuit board 201. Figure 4 , Figure 6As shown, there is a gap 213 between the edge of the circuit board 201 and the mounting housing 25, and the first heat dissipation air duct 211 and the second heat dissipation air duct 212 are connected through the gap 213. The first heat dissipation air duct 211 extends from the fan cavity 250 in a direction away from the air outlet 23, and the second heat dissipation air duct 212 extends in the direction of the air outlet 23.
[0073] Airflow enters the first heat dissipation duct 211 from the fan assembly 24 in the fan chamber 250, flows over the lower surface of the circuit board 201 and carries away heat, then enters the second heat dissipation duct 212 from the gap 213 between the edge of the circuit board 201 and the mounting housing 25, flows over the upper surface of the circuit board 201 and the transmitting coil 202 above the circuit board 201, carries away heat, and then flows to the air outlet 210 on the air outlet section 23. The arrangement of the first heat dissipation duct 211 and the second heat dissipation duct 212 increases the area through which the airflow passes over the transmitting assembly 20, thereby effectively improving the heat dissipation effect of the transmitting assembly 20.
[0074] In detail, such as Figure 4 , Figure 6 As shown, the air outlet 23 is located above the launching assembly 20. The end of the mounting housing 25 adjacent to the air outlet 23 is designated as the first end 251, and the end away from the air outlet 23 is designated as the second end 252. The mounting housing 25 located between the first end 251 and the second end 252 is configured to extend downwards to form a fan cavity 250. A circuit board 201 is disposed on the top of the mounting housing 25 and is configured to extend from a position corresponding to the fan cavity 250 to the second end 252 of the mounting housing 25.
[0075] Specifically, refer to Figure 4 , Figure 6 From a certain perspective, the first end 251 and the second end 252 of the mounting housing 25 are the left and right ends of the mounting housing 25. The top edge of the mounting housing 25 extends upward to form a perimeter and, together with the inner wall of the base station 2 above, forms a heat dissipation duct 21. The opening end of the fan cavity 250 communicates with the heat dissipation duct 21 above. The circuit board 201 is horizontally disposed in the heat dissipation duct 21. One end of the circuit board 201 is located above the fan cavity 250, that is, between the first end 251 and the second end 252 of the mounting housing 25, and the other end of the circuit board 201 extends to the second end 252 of the mounting housing 25. In a specific embodiment of this disclosure, the transmitting coil 202, the circuit board 201, and the fan assembly 24 are configured to be arranged sequentially in the height direction, which allows the airflow blown by the fan assembly 24 to directly act on the circuit board 201, improving the heat dissipation effect on the circuit board 201.
[0076] In one specific embodiment of this disclosure, reference is made to Figure 4 , Figure 7From a certain perspective, a seal 26 is provided on the mounting housing 25, located between the circuit board 201 and the fan assembly 24. The circuit board 201 is configured to be disposed at the open end of the fan cavity 250 via the seal 26, with one end of the circuit board 201 adjacent to the first end 251 of the mounting housing 25 sealed to the seal 26. A notch 260 for airflow is provided on the side wall of the seal 26 adjacent to the second end 252 of the mounting housing 25.
[0077] exist Figure 7 In the specific embodiment shown, the seal 26 is frame-shaped, and the cutout position of the seal 26 corresponds to the opening end of the fan cavity 250. The tops of the three sidewalls of the seal 26 are sealed to the circuit board 201, and a notch 260 is provided only on the sidewall of the seal 26 near the second end 252. This allows the airflow blown out by the motor assembly 24 to flow only through the notch 260 toward the second end 252 of the mounting housing 25, that is, toward the direction away from the air outlet 23.
[0078] The fan cavity 250 communicates with the heat dissipation duct 21 through a notch 260 on the seal 26. Airflow in the fan cavity 250 enters the first heat dissipation duct 211 below the circuit board 201 through the notch 260 on the seal 26. One end of the circuit board 201 adjacent to the first end 251 of the mounting housing 25 is sealed with the seal 26. The first heat dissipation duct 211 and the second heat dissipation duct 212 can only communicate through gaps 213 at other unsealed edges of the circuit board 201. In some embodiments of this disclosure, at least one edge of the circuit board 201 has a gap 213 for airflow. In a preferred embodiment, three edges of the circuit board 201 have gaps 213 to increase ventilation. Airflow entering the first heat dissipation duct 211 from the notch 260 flows to the gaps 213 on the three edges of the circuit board 201 and then enters the upper second heat dissipation duct 212.
[0079] Since the end of the circuit board 201 adjacent to the first end 251 of the mounting housing 25 is closer to the air outlet 23, sealing this end with the sealant 26 prevents the airflow in the first heat dissipation duct 211 from flowing to the air outlet 23 from the end with the shorter path. After the airflow in the fan cavity 250 enters the first heat dissipation duct 211 through the notch 260, it can only flow towards the second end 252 of the mounting housing 25 to the gap 213 at the edge of the circuit board 201, and then enters the second heat dissipation duct 212 through the gap 213, and then flows to the air outlet 23 through the second heat dissipation duct 212, thereby extending the path of the airflow through the first heat dissipation duct 211 and the second heat dissipation duct 212. When the airflow flows through the first heat dissipation duct 211, it can dissipate heat to the bottom of the circuit board 201. When the airflow meanders to the second heat dissipation duct 212, it can dissipate heat to the top of the circuit board 201 and the transmitting coil 202, thereby fully dissipating heat from the transmitting component 20 and improving the heat dissipation effect.
[0080] In one specific embodiment of this disclosure, reference is made to Figure 4 As shown, the transmitter assembly 20, fan assembly 24, and mounting housing 25 are installed in the base station 2 in the form of modules. The transmitter assembly 20 and fan assembly 24 can both be fixedly connected to the mounting housing 25 for easy installation and removal. For example, the transmitter assembly 20 and fan assembly 24 can be fixed to the mounting housing 25 by snap-fit, screw connection, or other detachable connection methods; the mounting housing 25 can be fixedly connected to the base station 2 by snap-fit, screw fixation, or other detachable connection methods.
[0081] In one specific embodiment of this disclosure, such as Figure 4 As shown, the position on the bearing surface 22 corresponding to the transmitting component 20 is configured with an extension cavity 221 protruding upward from the bearing surface 22, and the transmitting component 20 is configured to be at least partially located in the extension cavity 221. The transmitting component 20 and the receiving component 10 cooperate for charging, and the distance between them needs to be limited to a certain range; exceeding this range will prevent charging. The upward protrusion of the extension cavity 221 reduces the distance between the transmitting component 20 and the receiving component 10 above it, ensuring effective charging of both components. Specifically, the shape of the extension cavity 221 can be set to correspond to the shape of the transmitting component 20, with the transmitting coil 202 of the transmitting component 20 located within the extension cavity 221. Furthermore, the extension cavity 221 protruding from the bearing surface 22 has a larger contact area, which is beneficial for heat dissipation.
[0082] When the cleaning equipment 1 is working, it needs to use water to clean the working area. The floor brush assembly 12 is prone to water stains, which will be carried to the base station 2. If the water stains enter the base station 2 through the air outlet 210, it will cause damage to the components inside the base station 2. Although the air outlet 210 of the heat dissipation duct 21 is located on the side wall of the air outlet 23, water stains will inevitably enter the air outlet 210 when there are a lot of water stains.
[0083] In one embodiment of this disclosure, such as Figure 4 , Figure 6 As shown, to prevent water stains from damaging the components inside the base station 2, the first end 251 of the mounting housing 25 is configured to extend downward to form a receiving cavity 253. The receiving cavity 253 is located below the air outlet 23 and is configured to receive liquid entering from the air outlet 23. Water stains entering the base station 2 from the air outlet 210 fall into the receiving cavity 253 under the action of gravity, so as to prevent water stains from contacting the transmitting component 20 and the fan component 24.
[0084] In detail, the top of the receiving cavity 253 is connected to the heat dissipation duct 21, and the airflow in the heat dissipation duct 21 can flow from the top of the receiving cavity 253 to the upper air outlet 210. The receiving cavity 253 is disposed on the mounting housing 25 and is located at the first end 251 of the mounting housing 25 adjacent to the air outlet 23. The heat dissipation duct 21 and the fan cavity 250 are located on one side of the receiving cavity 253.
[0085] In one specific embodiment of this disclosure, such as Figure 4 , Figure 6 As shown, a drain hole 254 is provided at the bottom of the receiving cavity 253 to drain water stains from the receiving cavity 253. The water stains in the receiving cavity 253 can be discharged from the base station 2 through the drain hole 254. The drain hole 254 can be configured as a microporous structure, and its air volume is much smaller than that of the air outlet 210. Part of the airflow in the heat dissipation duct 21 can be discharged through the drain hole 254. Reducing the opening area of the drain hole 254 can reduce the negative pressure loss from the drain hole 254.
[0086] In one specific embodiment of this disclosure, such as Figure 4 , Figure 6 As shown, the receiving cavity 253 extends from the position corresponding to the air outlet 23 toward the second end 252 of the mounting housing 25, offset from the air outlet 23 by a predetermined distance. The vertical downward projection of the air outlet 23 falls into the receiving cavity 253. The extension of the receiving cavity 253 toward the second end 252 of the mounting housing 25 by a certain distance ensures that the air outlet 23 is at a certain distance from the emitting component 20 in the heat dissipation duct 21 in the horizontal direction, so as to prevent water stains entering from the air outlet 210 from contacting the emitting component 20.
[0087] In detail, such as Figure 4 , Figure 6As shown, the mounting housing 25 has a vertically extending partition plate 255. A receiving cavity 253 is located on the side of the partition plate 255 near its first end 251, and a fan cavity 250 is located on the side of the partition plate 255 near its second end 252. An extension cavity 221 extends from above the partition plate 255 to the second end 252 of the mounting housing 25. A gap is left between the top of the partition plate 255 and the inner wall of the base station 2. Airflow in the heat dissipation duct 21 enters above the receiving cavity 253 through the top of the partition plate 255 and flows out from the air outlet 23. From another perspective, the partition plate 255 corresponds to the bearing surface 22 and is offset from the air outlet 23 by a predetermined distance, thereby causing the receiving cavity 253 to extend relative to the air outlet 23 towards the second end 252, thus preventing water from entering the second heat dissipation duct 212 through the air outlet 23. In addition, the side of the receiving cavity 253 opposite to the partition plate 255 can be configured to gradually extend outward from bottom to top to form a flared structure, which is beneficial for receiving water dripping from the air outlet 23.
[0088] In one embodiment of this disclosure, such as Figure 4 As shown, a baffle plate 231 is also provided at the air outlet 210. The baffle plate 231 extends upwards and at an angle from the bottom edge of the air outlet 210 toward the interior of the air outlet 23. The airflow needs to bypass the upper end of the baffle plate 231 before being discharged from the air outlet 210. The baffle plate 231 can prevent external water stains from entering through the air outlet 210, further improving the security of the base station 2.
[0089] In one embodiment of this disclosure, such as Figure 4 , Figure 8 As shown, the base station 2 has a cavity 27 for accommodating a drawer 28, which is located below the bearing surface 22 and can be used to store accessories or other items for the cleaning system. The air inlet 241 of the fan assembly 24 aligns with an opening 271 on the side wall of the cavity 27. Airflow from the cavity 27 can enter the air inlet 241 of the fan assembly 24 through the opening 271. Furthermore, the drawer 28 can have through holes corresponding to the opening 271, allowing air from the drawer 28 to be drawn in by the fan assembly 24, which helps remove odors from the drawer 28 and reduces bacterial growth.
[0090] In detail, such as Figure 8 As shown, drawer 28 can be pulled out from the open end of cavity 27, and the air inlet 241 of fan assembly 24 aligns with the opening 271 on the side wall of cavity 27. When drawer 28 is stored inside cavity 27, a gap remains between it and cavity 27, and a through hole communicating with cavity 27 can be provided at the bottom of base station 2, allowing outside air to enter cavity 27 from the bottom of base station 2 and enter the air inlet 241 of fan assembly 24 from the opening 271 on the side wall of cavity 27.
[0091] This disclosure also provides a base station, base station 2, configured to interface with cleaning device 1. Base station 2 is provided with a transmitting component 20 for wireless charging, the transmitting component 20 being configured to cooperate with a receiving component 10 on cleaning device 1 after the cleaning device 1 interfaces with base station 2, so as to wirelessly charge the cleaning device 1 via base station 2.
[0092] The base station 2 is provided with a heat dissipation duct 21, which forms an air outlet 210 on the base station 2. The airflow discharged from the air outlet 210 is configured to blow towards the mating area of the receiving component 10 and the transmitting component 20.
[0093] The base station 2 and the cleaning device 1 connected to the base station 2 provided in this disclosure are completely identical to the base station and cleaning device of the above-mentioned cleaning system. The specific structure, principle and effect of the base station 2 and the cleaning device 1 can be referred to the above-mentioned cleaning system, and will not be repeated here.
[0094] The technical solution adopted in this disclosure will be explained below with reference to a specific application scenario to aid understanding. In the application scenario below, cleaning equipment 1 is a floor scrubber as an example.
[0095] Application Scenario 1
[0096] After the floor scrubber has been in use for a period of time, it connects to the base station 2 for wireless charging. The floor scrubber's brush assembly 12 connects to the support surface 22 of the base station 2. The receiving component 10 at the bottom of the brush assembly 12 cooperates with the transmitting component 20 on the base station 2, and the transmitting component 20 wirelessly charges the receiving component 10.
[0097] During wireless charging, the transmitting component 20 and the receiving component 10 generate significant heat. The base station 2 uses a heat dissipation duct 21 to cool the transmitting component 20 and the receiving component 10. The fan assembly 24 inside the base station 2 creates a negative pressure in the fan cavity 250. The air inlet 241 of the fan assembly 24 draws air into the cavity 27 inside the base station 2. Air in the cavity 27 and the drawer 28 is drawn into the fan assembly 24 through the opening 271 on the side wall of the cavity 27. The airflow blown out by the fan assembly 24 enters the upper heat dissipation duct 21 through the notch 260 on the seal 26, cooling the transmitting component 20 within the heat dissipation duct 21.
[0098] The airflow in the fan cavity 250 first enters the first heat dissipation duct 211 below the circuit board 201 of the transmitting component 20 through the notch 260, carrying away the heat from the lower surface of the circuit board 201. Then, it enters the second heat dissipation duct 212 above the circuit board 201 through the gap 213 at the edge of the circuit board 201, carrying away the heat from the upper surface of the circuit board 201 and the transmitting coil 202 above the circuit board 201. The first heat dissipation duct 211 and the second heat dissipation duct 212 are in full contact with the transmitting component 20, which can improve the heat dissipation efficiency of the transmitting component 20.
[0099] The airflow in the second heat dissipation duct 212 eventually flows to the air outlet 23 above the receiving cavity 253 and is discharged from the air outlet 210 on the side wall of the air outlet 23. The discharged airflow flows to the gap 220 between the transmitting component 20 and the receiving component 10 under the guidance of the guide surface 121, thereby further dissipating heat from the transmitting component 20 and the receiving component 10.
[0100] Application Scenario 2
[0101] After the floor scrubber has been working for a period of time, it connects to the base station 2 for wireless charging. The floor scrubber's brush assembly 12 connects to the support surface 22 of the base station 2. Water stains carried by the brush assembly 12 during operation are carried onto the support surface 22. The air outlet 210 on the support surface 22 for heat dissipation is located low, and water stains can easily enter the air outlet 210. A baffle 231 is provided at the air outlet 210 to prevent water stains from entering the air outlet 210.
[0102] When there is a lot of water, it can pass over the baffle plate 231 and enter the base station 2. After passing over the baffle plate 231, the water falls into the receiving cavity 253 below the air outlet 210 under the action of gravity, and then is discharged from the base station 2 through the leakage hole 254 at the bottom of the receiving cavity 253, thereby protecting the transmitting component 20, the fan component 24 and other components inside the base station 2 and improving safety.
[0103] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein. The scope of this disclosure is defined by the appended claims.
