Also known as automatic cleaning robots, intelligent vacuum cleaners, or robotic vacuums, robotic vacuum cleaners are a type of smart home appliance. They are typically capable of autonomous movement and, using artificial intelligence, automatically clean floors and other surfaces within a room. However, when cleaning or charging, some components within the robotic vacuum cleaner generate considerable heat. The limited internal space of the robot makes it difficult to install adequate heat dissipation devices, which can negatively impact its performance. Summary of the Invention

[0027] This disclosure provides a cleaning device, which can be a robot vacuum cleaner, a robot mop, a robot vacuum and mop combo, or other cleaning devices that meet the requirements.

[0028] In some embodiments, the cleaning equipment includes, but is not limited to, a device body, a mobile platform, sensing components, control components, cleaning components, energy components, and human-machine interaction components. These components coordinate with each other to enable the cleaning equipment to move autonomously to perform its cleaning function. The functional elements constituting these components are integrated into the device body. It is understood that the cleaning equipment can be a self-moving cleaning device, which is a device that automatically performs cleaning operations in a designated area without user intervention.

[0029] Referring to Figures 1 and 2, Figure 1 is a structural schematic diagram of the cleaning equipment provided in this disclosure, and Figure 2 is a partial enlarged view of the cleaning equipment provided in this disclosure. The cleaning equipment provided in this embodiment includes: a housing, a dust box 2, and an airflow generator 3. The housing forms a receiving cavity 11, and the receiving cavity 11 has a receiving area for receiving a heating element; the dust box 2 is disposed within the receiving cavity 11; the airflow generator 3 is disposed within the receiving cavity 11 and is in airflow communication with the dust box 2; the receiving cavity 11 has an exhaust channel 4, which is in airflow communication with the airflow generator 3, and the end of the exhaust channel 4 facing away from the airflow generator 3 has an airflow discharge section 42, which is in airflow communication with the receiving area.

[0030] In this embodiment, the housing can provide mounting points, support, and protection for other components in the cleaning equipment. The external shape and internal structure of the housing can be designed according to the shape and distribution of other components in the cleaning equipment to facilitate the installation of various components inside and outside the housing.

[0031] In some embodiments, as shown in FIG1, the housing can be configured as a box-shaped structure with a cavity to form a receiving cavity 11 within the housing. In some embodiments, the housing can be configured as a near-cylindrical structure. A receiving area for mounting heating elements can be provided within the receiving cavity 11 of the housing; for example, the area within the receiving cavity 11 near the front end of the cleaning device can be used as the receiving area. Components that generate a significant amount of heat during operation can be placed within the receiving area. The front end of the cleaning device is the end located in front of the cleaning device as it moves forward in the direction X, which is the end where the side brush 8 is located.

[0032] In this embodiment, a dustbin 2 can be disposed within the housing and located within the receiving cavity 11. In some embodiments, the dustbin 2 can be a recess protruding into the receiving cavity 11, with the opening of the recess facing the bottom of the cleaning device. The shape of the dustbin 2 can be configured according to the shape of the dust box of the cleaning device to facilitate the installation of the dust box within the dustbin 2. In some embodiments, the dustbin 2 can be disposed in the region near the center of the housing within the receiving cavity 11, and the long axis of the dustbin 2 can be perpendicular or nearly perpendicular to the travel direction X of the cleaning device.

[0033] In this embodiment of the present disclosure, as shown in FIG1, an airflow generator 3 can be disposed within the accommodating cavity 11. The airflow generator 3 can accelerate the airflow speed to create a negative pressure in the area adjacent to the airflow generator 3. In some embodiments, the airflow generator 3 can be an axial fan, a centrifugal fan, or a plasma fan, etc.

[0034] In some embodiments, an air intake channel can be provided between the airflow generator 3 and the dust box 2 to connect the air intake of the airflow generator 3 with the dust box 2, thereby enabling airflow communication between the airflow generator 3 and the dust box 2. In some embodiments, a notch matching the air intake channel can be provided on the wall of the dust box 2, and the edge of the air intake channel can be sealed to the notch. In this way, during the operation of the airflow generator 3, the speed at which the air inside the dust box 2 flows into the air intake channel can be accelerated, thereby making the air pressure inside the dust box 2 lower than the air pressure outside the dust box 2, so that debris can be sucked into the dust box located inside the dust box 2 through negative pressure.

[0035] In this embodiment of the present disclosure, as shown in Figures 1 and 2, an exhaust channel 4 can be provided within the accommodating cavity 11. One end of the exhaust channel 4 can be configured to match the air outlet of the airflow generator 3, so that the air outlet of the airflow generator 3 is connected to the airflow of the exhaust channel 4. The other end of the exhaust channel 4 can extend to the outside of the accommodating cavity 11, that is, the airflow discharge part 42 of the exhaust channel 4 away from the airflow generator 3 is connected to the airflow outside the housing.

[0036] In some embodiments, the airflow discharge section 42 can be in airflow communication with the receiving area within the receiving cavity 11, meaning that air within the receiving area can flow to the airflow discharge section 42 and then from the airflow discharge section 42 to the outside of the receiving cavity 11. In some embodiments, a notch can be provided at the end of the exhaust channel 4 away from the airflow generator 3 to allow the exhaust channel 4 to be in airflow communication with the receiving area. In this way, during the operation of the airflow generator 3, the high-velocity airflow blown out by the airflow generator 3 can be quickly discharged to the outside of the housing under the guidance of the exhaust channel 4, so that the airflow generator 3 can operate normally.

[0037] The cleaning device provided in this embodiment has a receiving area within the housing cavity 11, allowing components that generate significant heat to be housed within this area. Furthermore, the airflow generator 3 is connected to the dustbin 2 via airflow communication, creating a negative pressure within the dustbin 2 to facilitate the suction of items to be cleaned into the dustbin. Simultaneously, the airflow generator 3 is equipped with an exhaust channel 4, and the airflow discharge section 42 of the exhaust channel 4 is connected to the receiving area. During the rapid discharge of the high-velocity airflow from the airflow generator 3 to the outside of the housing via the exhaust channel 4, the air pressure near the airflow discharge section 42 decreases due to the high-velocity airflow. This results in the air pressure near the airflow discharge section 42 being lower than the air pressure in the receiving area. This pressure difference allows air within the receiving area to flow towards the airflow discharge section 42, rapidly dissipating the heat generated by the heating components within the receiving area to the outside of the housing, thus achieving effective heat dissipation for the heating components located within the receiving area of ​​the cleaning device.

[0038] In some embodiments of this disclosure, as shown in FIG1, the housing includes a lower housing 1 and an upper housing (not shown in the figure). The lower housing 1 is provided with a receiving area, and a heating element is provided in the receiving area; the upper housing and the lower housing 1 are connected, and at least one of the upper housing and the lower housing 1 has a gap with the heating element so that the airflow discharge part 42 and the receiving area are in airflow communication.

[0039] In this embodiment, the housing can be configured as a structure including a lower housing 1 and an upper housing. The lower housing 1 can be configured as an approximately cylindrical box shape (with an opening), thereby forming a cavity within the lower housing 1 that can accommodate components of the cleaning device. A portion of the space within the cavity can be used as a receiving area, for example, the front half or the rear half of the cavity can be used as a receiving area. The upper housing can be configured as a disc-shaped cover that matches the opening of the lower housing 1, and the upper housing is fastened onto the opening of the lower housing 1 to enclose and form a receiving cavity 11.

[0040] In some embodiments, a heating element can be disposed within the accommodating area. In some embodiments, the heating element may include a motherboard assembly, power supply, and part of a drive motor, etc., disposed within the accommodating area of ​​the cleaning device. When the heating element is disposed within the accommodating area, the space for mounting the heating element can be set to be larger than the volume of the heating element. Thus, when the heating element is installed within the accommodating area, there can be a gap between the heating element and the upper housing or the lower housing 1, or gaps can be formed between the heating element and both the upper and lower housing 1. This allows air within the accommodating area to flow within the gaps between the heating element and the upper housing, and between the heating element and the lower housing 1, thereby allowing air around the heating element to flow to the airflow exhaust section 42.

[0041] In the above embodiments, the housing is configured to include a lower housing 1 and an upper housing, which facilitates the processing of the housing. Furthermore, by having a gap between at least one of the upper and lower housings 1 and the heating element, the gap between the upper and lower housings 1 and the heating element can serve as a channel for airflow within the accommodating area, thereby allowing air around the heating element to flow towards the airflow discharge section 42.

[0042] In some embodiments of this disclosure, the accommodating cavity 11 includes a first accommodating portion and a second accommodating portion. Along the traveling direction X of the cleaning equipment, the first accommodating portion is located at the front side of the dust box 2, and the second accommodating portion is located at the rear side of the dust box 2. The airflow generator 3 and the heating element are located in the first accommodating portion.

[0043] In this embodiment of the present disclosure, as shown in FIG1, the dustbin 2 can be formed by extending from the bottom wall of the lower housing 1 into the lower housing 1, and the dustbin 2 is located in the region of the lower housing 1 near the center of the lower housing 1. In this way, the dustbin 2 divides the lower housing 1 into two regions, that is, along the traveling direction X of the cleaning equipment, the dustbin 2 divides the receiving cavity 11 into two parts. The part of the receiving cavity 11 located on the front side of the dustbin 2 can be used as the first receiving part, and the part of the receiving cavity 11 located on the rear side of the dustbin 2 can be used as the second receiving part.

[0044] In some embodiments, at least a portion of the first accommodating part can be used as an accommodating area. An airflow generator 3 can be disposed within the first accommodating part. A heating element can be disposed within the accommodating area of ​​the first accommodating part. This allows the airflow generator 3 and the heating element to be located in the front half of the cleaning device.

[0045] In the above embodiment, since the housing cavity 11 of the shell is divided into a first accommodating part and a second accommodating part by the dust box 2, at least a portion of the area within the first accommodating part can be used as an accommodating area. Furthermore, since both the airflow generator 3 and the heating element are located within the first accommodating part, during the process of using the negative pressure generated by the airflow generator 3 within the accommodating area to dissipate heat and cool the heating element, the airflow generator 3 can also be cooled, which helps to keep the airflow generator 3 within a suitable temperature range.

[0046] In some embodiments of this disclosure, as shown in FIG1, the airflow discharge portion 42 is at least partially located on the sidewall of the first receiving portion, the sidewall being a wall extending in the thickness direction of the cleaning device within the housing.

[0047] In this embodiment of the present disclosure, the airflow discharge section 42 can be disposed on the side wall of the housing, or a portion of the side wall of the housing can be used as a structure to enclose and form the airflow discharge section 42.

[0048] In some embodiments, the airflow discharge section 42 may be disposed on the side wall of the lower housing 1. In some embodiments, the airflow discharge section 42 may be disposed on the side wall adjacent to the first receiving portion. The portion of the side wall adjacent to the first receiving portion may be configured as having a sandwich structure, and the sandwich structure may be in communication with the outside of the lower housing 1. The sandwich structure has a notch on the side near the upper housing, so that the gap in the sandwich structure can be in communication with the airflow of the receiving area. The sandwich structure may be used as the airflow discharge section 42.

[0049] In the above embodiments, since at least a portion of the airflow discharge section 42 is located on the side wall of the first accommodating section, the space occupied by the airflow discharge section 42 in the first accommodating section can be reduced, which is beneficial to increasing the spatial volume of the first accommodating section.

[0050] In some embodiments of this disclosure, as shown in FIG1, an air inlet 44 is provided on the housing, and the air inlet 44 and the air outlet 42 are in airflow communication. When the airflow generator 3 is working, a cooling airflow is formed between the air inlet 44 and the air outlet 42, and the cooling airflow passes at least partially through the heating element.

[0051] In this embodiment of the present disclosure, an air inlet 44 may be provided on the housing so that air around the cleaning device can flow into the accommodating area through the air inlet 44.

[0052] In some embodiments, the air inlet 44 can be disposed on the side wall of the housing, that is, a notch is provided on the side wall of the lower housing 1 to allow airflow communication between the first receiving portion and the outside of the housing through the notch. In some embodiments, the air inlet 44 can be disposed on the side of the housing away from the airflow discharge portion 42, that is, the distance between the air inlet 44 and the airflow discharge portion 42 is made as far as possible. For example, the air inlet 44 and the airflow discharge portion 42 are substantially located on the same diameter of the cleaning device.

[0053] In another embodiment, a gap can be made between the components located in the accommodating cavity 11 and the upper housing, thereby allowing airflow communication between the air inlet 44 and the airflow outlet 42. In this way, as the airflow generator 3 blows high-velocity gas into the exhaust channel 4, the air pressure near the area (close to the airflow outlet 42) where the airflow outlet 42 communicates with the accommodating area decreases. This allows air in the accommodating area to flow towards the airflow outlet 42, enabling the surrounding air outside the cleaning equipment to sequentially pass through the air inlet 44, the accommodating area, and the airflow outlet 42 before being discharged to the outside of the cleaning equipment. This also creates a cooling airflow between the air inlet 44 and the airflow outlet 42, which can absorb the heat generated by the heating element for efficient heat dissipation and cooling.

[0054] In the above embodiment, since the housing is provided with an air inlet 44 and the air inlet 44 and the air outlet 42 are in airflow communication, the air between the air inlet 44 and the air outlet 42 can flow from the air inlet 44 to the air outlet 42 through the air pressure difference between the air outlet 42 and the air inlet 44. This allows the air with a lower external temperature to pass through the air inlet 44 and form a cooling airflow that flows through the heat-generating component, thereby achieving efficient heat dissipation of the heat-generating component through the cooling airflow.

[0055] In some embodiments of this disclosure, as shown in FIG1, the air inlet 44 and the air outlet 42 are located on opposite sides of the housing along a direction perpendicular to the travel direction X of the cleaning device.

[0056] In this embodiment, the air inlet 44 and the air outlet 42 can be respectively disposed on opposite sides of the housing, and the air inlet 44 and the air outlet 42 can be respectively located on opposite sides of the first accommodating portion.

[0057] In some embodiments, the air inlet 44 can be disposed on one side of the housing along a direction perpendicular to the travel direction X of the cleaning device, i.e., the first direction Y as shown in FIG1, and the air outlet 42 can be disposed on the other side of the housing. In some embodiments, the air inlet 44 and the air outlet 42 can be located on the diameter of the cleaning device along the first direction Y, so that the distance between the air inlet 44 and the air outlet 42 is as far as possible.

[0058] In another embodiment, the heating element includes a motherboard assembly (not shown in the figure), and at least a portion of the motherboard assembly can be located between the air inlet 44 and the airflow outlet 42. In some embodiments, along the thickness direction of the cleaning device (as shown in Figure 1, perpendicular to the paper plane or nearly perpendicular to the paper plane), the motherboard assembly can be disposed on the side of the airflow generator 3 away from the bottom wall of the lower housing 1, that is, at least a portion of the motherboard assembly is stacked with the airflow generator 3. In this way, not only can the space occupied by the motherboard assembly in the accommodating area be reduced, which is beneficial to the lightweighting and miniaturization of the cleaning device; but also the cooling airflow flowing through the accommodating area can flow through the motherboard assembly, thereby absorbing the heat generated by the components on the motherboard assembly through the cooling airflow, so as to achieve heat dissipation and cooling of the motherboard assembly.

[0059] In the above embodiments, since the air inlet 44 and the air outlet 42 are located on opposite sides of the housing, the flow path of the cooling airflow between the air inlet 44 and the air outlet 42 can be increased, thereby allowing the cooling airflow to flow through more components inside the housing, which is beneficial to improving the heat dissipation efficiency of the cleaning equipment.

[0060] In some embodiments of this disclosure, as shown in FIG1, the exhaust channel 4 has a negative pressure gap 41 (the area shown by the red dashed triangle in FIG1). The negative pressure gap 41 is in airflow communication with the accommodating area, and the airflow discharge part 42 is in airflow communication with the accommodating area through the negative pressure gap 41. During the process of the airflow generated by the airflow generator 3 flowing through the exhaust channel 4, the air pressure at the negative pressure gap 41 is lower than the air pressure in the accommodating area under the action of the airflow.

[0061] In this embodiment of the present disclosure, the exhaust channel 4 can be configured as a tubular structure, with the tubular exhaust channel 4 extending from the air outlet of the airflow generator 3 to the outside of the housing.

[0062] In some embodiments, a negative pressure notch 41 may be provided on the exhaust channel 4. For example, a through hole or notch may be provided on the wall that encloses the exhaust channel 4, and the through hole or notch may be provided on the part of the exhaust channel 4 located in the receiving area, so that the exhaust channel 4 and the receiving area can be connected by airflow through the negative pressure notch 41, and the receiving area and the airflow discharge part 42 can be connected by airflow through the negative pressure notch 41.

[0063] In the above embodiment, since a negative pressure notch 41 is provided on the exhaust channel 4, the exhaust channel 4 can be connected to the accommodating area through the negative pressure notch 41, thereby allowing airflow communication between the accommodating area and the airflow discharge section 42. Thus, during the airflow process in the exhaust channel 4, the air pressure near the negative pressure notch 41 decreases under the action of the airflow in the exhaust channel 4, thereby making the air pressure near the negative pressure notch 41 lower than the air pressure in the accommodating area, and allowing air in the accommodating area to flow into the exhaust channel 4 through the negative pressure notch 41.

[0064] In some embodiments of this disclosure, as shown in FIG1, the heating element includes a battery, a power supply compartment 5 is provided in the accommodating area, and an exhaust channel 4 passes through the compartment wall of the power supply compartment 5.

[0065] In this embodiment, a battery can be used to provide power to the cleaning equipment. For example, a rechargeable battery (a battery that can be charged and discharged multiple times) or a regular battery can be used to power the cleaning equipment. The battery generates heat during charging and discharging; therefore, the battery can be installed within the receiving area of ​​the receiving cavity 11 to accelerate heat dissipation.

[0066] In some embodiments, a power compartment 5 for installing a battery can be provided inside the lower housing 1. The shape of the power compartment 5 can be set according to the shape of the battery used. In some embodiments, the power compartment 5 can be set as a box-shaped structure with an approximate cuboid shape. The opening of the power compartment 5 is located on the surface of the lower housing 1 facing the bottom of the cleaning device, and the cover of the power compartment 5 can be opened from the bottom of the cleaning device.

[0067] In another embodiment, a portion of the exhaust channel 4 can be located adjacent to the power supply compartment 5. For example, a portion of the channel wall of the exhaust channel 4 can abut against the wall of the power supply compartment 5, or a portion of the wall of the power supply compartment 5 can be used as the channel wall to enclose and form the exhaust channel 4, so that the exhaust channel 4 passes through the wall of the power supply compartment 5.

[0068] In the above embodiment, since the accommodating area is provided with a power compartment 5, it is convenient to install the battery in the cleaning equipment through the power compartment 5. Furthermore, the exhaust channel 4 passes through the wall of the power compartment 5. When the battery generates heat during charging and discharging, the wall of the power compartment 5 absorbs the heat generated by the battery, and the airflow in the exhaust channel 4 can quickly absorb the heat absorbed by the wall of the power compartment 5, thereby cooling the power compartment 5 and achieving good heat dissipation for the battery inside the power compartment 5.

[0069] In some embodiments of this disclosure, as shown in Figures 1 and 2, the exhaust passage 4 includes a surrounding passage 43, and the airflow discharge part 42 includes an extension passage 422 (the area shown by the blue dashed rectangle in the figure). The surrounding passage 43 and the extension passage 422 are in airflow communication. The surrounding passage 43 passes through at least one wall of the power supply compartment 5, and the extension passage 422 extends along the extension direction of the side wall of the housing.

[0070] In this embodiment of the present disclosure, the airflow exhaust section 42 can be configured to include an air outlet 421 and an extension channel 422, and a surrounding channel 43 can be provided in the exhaust channel 4, with the surrounding channel 43 passing through the power supply compartment 5.

[0071] In this embodiment, a surrounding channel 43 matching the shape of the power supply compartment 5 can be provided. The surrounding channel 43 can be configured as a tubular structure, serving as part of a heat dissipation channel. For example, the shape of the surrounding channel 43 can be determined based on the shape of the gap between the power supply compartment 5 and other components adjacent to it. One end of the surrounding channel 43 can be configured to match the air outlet of the airflow generator 3, and this end of the surrounding channel 43 can be connected to the air outlet of the airflow generator 3.

[0072] In some embodiments, an airflow guide 6 can be provided in the cleaning device, and a surrounding channel 43 can be formed within the airflow guide 6. The first end 61 of the airflow guide 6 matches the air outlet of the airflow generator 3 and is connected to the airflow at the outlet. The second end 62 of the airflow guide 6 is adjacent to the airflow discharge section 42. In some embodiments, the airflow guide 6 can be manufactured using a material with good thermal conductivity. The sidewall of the airflow guide 6 can abut against the wall of the power supply compartment 5. Alternatively, a material with good thermal conductivity, such as thermally conductive grease or thermally conductive silicone, can be provided between the sidewall of the airflow guide 6 and the wall of the power supply compartment 5, so that the heat absorbed by the wall of the power supply compartment 5 can be quickly transferred to the airflow guide 6.

[0073] In some embodiments, a notch matching the power supply compartment 5 can be provided on the airflow guide 6. After the airflow guide 6 is installed in the accommodating area, the wall of the power supply compartment 5 can seal the notch on the airflow guide 6. That is, the wall of the power supply compartment 5 becomes part of the channel wall of the surrounding channel 43, so that the surrounding channel 43 forms a complete tubular structure. This allows the heat absorbed by the wall of the power supply compartment 5 to be directly transferred to the exhaust channel 4. By providing the airflow guide 6, it is convenient to form the surrounding channel 43 within the accommodating cavity 11.

[0074] In another embodiment, an air outlet 421 can be provided on the outer wall of the housing, and the second end 62 of the airflow guide 6 can be extended to a position adjacent to the air outlet 421 (at this time, the extension channel 422 can be omitted, and the air outlet 421 can be used as the airflow discharge part 42). There can be a gap between the second end 62 of the airflow guide 6 and the air outlet 421, and this gap can be used as a negative pressure gap 41.

[0075] In this embodiment, the second end 62 of the airflow guide 6 can be located near the side wall of the housing, and another part of the exhaust channel 4 can be extended along the side wall of the housing, that is, the airflow discharge part 42 and the surrounding channel 43 are connected by airflow through the extension channel 422 extending along the side wall of the housing.

[0076] In some embodiments, the sidewall of the housing may be configured to have an extended through-hole extending along the circumference of the cleaning device on the sidewall of the housing, thereby forming an extended channel 422 on the housing. One end of the extended through-hole may be adjacent to the second end 62 of the airflow guide 6, and a gap may be maintained between the second end 62 of the airflow guide 6 and the extended through-hole, which may serve as a negative pressure notch 41.

[0077] In another embodiment, as shown in FIG1, when an extension through hole as an extension channel 422 is provided on the side wall of the housing, an air outlet 421 can be provided on the side wall of the housing. That is, the end of the extension through hole away from the surrounding channel 43 is provided on the outer wall of the housing away from the receiving cavity (the wall in the housing located on the outer surface of the cleaning device), and the end of the extension through hole away from the surrounding channel 43 is used as the air outlet 421.

[0078] In another embodiment, the cleaning device further includes an outer trim 7, which forms an extension channel 422 between itself and the side wall of the housing, thereby forming at least a portion of the airflow discharge portion 42. In some embodiments, when providing the outer trim 7 of the cleaning device, a continuous gap may be provided between the outer trim 7 and the side wall of the housing, and at least a portion of the gap between the outer trim 7 and the side wall may serve as the extension channel 422. Alternatively, a notch may be provided on the outer trim 7 so that the extension channel 422 communicates with the airflow outside the housing through the notch, and the notch on the outer trim 7 serves as the air outlet 421 in the airflow discharge portion 42. The notch on the outer trim 7 and the side wall of the housing together enclose and form the airflow discharge portion 42.

[0079] In some embodiments, the front collision plate of the cleaning device can be used as part of the exterior trim 7. When the front collision plate is installed, a continuous gap is formed between the front collision plate and the side wall of the lower housing 1, so that the extension channel 422 is formed by the front collision plate and the side wall. The end of the front collision plate (the free end of the front collision plate near the rear end of the cleaning device along the traveling direction of the cleaning device) can be made not to abut against the side wall of the lower housing, so that there is a gap between the end of the front collision plate and the side wall of the lower housing. The gap between the end of the plate and the side wall of the lower housing can be used as the air outlet 421, that is, the air outlet 421 in the airflow discharge section 42 is located at the rear end of the end of the front collision plate. With this structure, the airflow discharge section 42 can be formed by the front collision plate and the side wall of the housing, thereby saving the structure of the airflow discharge section 42 that needs to be set separately on the housing, which helps to simplify the structure of the cleaning device. Furthermore, extending the airflow exhaust section 42 to the rear half of the cleaning device allows the airflow from the exhaust channel 4 to flow toward the rear end of the cleaning device, which helps reduce the risk of the airflow from the exhaust channel 4 blowing away the garbage to be cleaned at the front of the cleaning device.

[0080] In this embodiment of the present disclosure, as shown in Figures 1 and 2, along the travel direction X of the cleaning device, the second end 62 of the airflow guide 6 faces the rear end of the cleaning device and the second end 62 faces the extension channel 422.

[0081] In this embodiment of the disclosure, when the airflow guide 6 is configured, its second end 62, near the extension channel 422, can be positioned towards the rear end of the cleaning device. In some embodiments, the airflow guide 6 can be configured as an approximately U-shaped tubular structure, allowing the concave portion of the airflow guide 6 to abut against the wall of the power supply compartment 5, and positioning the airflow guide 6 on the side of the power supply compartment 5 near the front end of the cleaning device. In this way, the second end 62 of the airflow guide 6 is tilted towards the rear end of the cleaning device and towards the extension channel 422. This allows the airflow generated by the airflow generator 3 to be blown towards the rear end of the cleaning device through the surrounding channel 43, the extension channel 422, and the air outlet 421.

[0082] In addition, this disclosure also provides a cleaning system, which includes a base station and the cleaning equipment provided in any of the above embodiments. The base station is used to dock the cleaning equipment.

[0083] In this embodiment of the disclosure, when the cleaning equipment starts working, it departs from the base station to perform the cleaning task. When the cleaning equipment performs charging or other operations, such as water replenishment, and / or washing, and / or dust collection, it returns to the base station to complete the charging and other operations.

[0084] The cleaning system provided in this disclosure includes the cleaning device provided in any of the above embodiments. Therefore, it can achieve good heat dissipation of the heat-generating components located in the accommodating area within the cleaning device, which is beneficial to improving the performance of the cleaning system.

[0085] The cleaning equipment and cleaning system disclosed herein can achieve good heat dissipation of the heat-generating components inside the cleaning equipment.
