Description

Technical Field

[0001] This application relates to the field of intelligent cleaning technology, and in particular to a cleaning robot and cleaning system. Background Technology

[0002] As people's living standards continue to improve, cleaning appliances have gradually entered people's daily lives. Currently, cleaning systems on the market are equipped with a mop that can wipe the floor while sweeping. Cleaning robots with wet mopping functions often use hot water mopping technology to improve the cleaning effect on stubborn stains such as oil stains.

[0003] Currently, there are two main implementation solutions: one is the base station heating and delivery method. The cleaning base station heats the water and then pumps it to the robot's onboard water tank via pipelines. However, this method suffers from poor heat utilization efficiency because of the long delivery path and heat loss through the pipelines, resulting in a significantly lower temperature of the hot water by the time it reaches the mop.

[0004] Another method is the main unit casing water tank heating type: a heating element is installed in the water tank of the robot body to heat the water in the tank, and then the hot water is used to wet the cloth. Although this method shortens the hot water delivery distance, heat is still lost in the water tank and water supply pipeline, and the energy consumption for heating the entire water tank is relatively high, and the response speed is slow.

[0005] Both of the above methods result in insufficient temperature of the cloth applied to the cleaning surface due to heat loss during the storage and transportation of the transfer medium (water), making it difficult to achieve the desired cleaning effect on stubborn stains, and the energy efficiency is relatively low. Summary of the Invention

[0006] Therefore, it is necessary to address the problem that the current method of using a base station or host casing water tank to deliver hot water to the rag results in heat damage that affects the cleaning effect.

Detailed Implementation

[0045] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0046] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0047] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact, or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0050] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0051] Understandably, most cleaning systems on the market are equipped with mops that can wipe the floor while sweeping. Cleaning robots with wet mopping capabilities often use hot water to improve their effectiveness against stubborn stains like oil.

[0052] Currently, there are two main implementation solutions: one is the base station heating and delivery method. The cleaning base station heats the water and then pumps it to the robot's onboard water tank via pipelines. This method suffers from poor heat utilization efficiency because of the long delivery path and heat loss during pipeline transport, resulting in a significant temperature drop by the time the hot water reaches the mop. The other method is the main unit casing water tank heating method: a heating element is installed inside the robot's water tank to heat the water, which is then used to wet the mop. While this method shortens the hot water delivery distance, heat is still lost in the water tank and pipelines, and heating the entire tank consumes a lot of energy, resulting in a slow response time.

[0053] Both of the above methods result in insufficient temperature of the cloth applied to the cleaning surface due to heat loss during the storage and transportation of the transfer medium (water), making it difficult to achieve the desired cleaning effect on stubborn stains, and the energy efficiency is relatively low.

[0054] For this purpose, please refer to Figure 1 and Figure 2 This application provides a cleaning robot 10. The cleaning mechanism 100 is used in a cleaning system (not shown). Figure 1 This is a schematic diagram of the cleaning mechanism 100 in a cleaning robot 10 according to an embodiment of this application. Figure 2 for Figure 1 The schematic diagram of the cleaning robot 10 shown is as follows, and, Figure 2 The output sleeve 200 of the cleaning robot 10 is shown, but the main unit housing is not shown. The cleaning system includes a base station (not shown) and the cleaning robot 10, which can drive into, out of, or dock at the base station. After the cleaning robot 10 docks at a set position on the base station, the base station can provide the cleaning robot 10 with functional services such as charging and cleaning the cleaning cloth 132.

[0055] See Figure 1 and Figure 2 In one embodiment, the cleaning robot 10 includes a main housing (not shown) and a cleaning mechanism 100, which is disposed on the main housing and at least partially protrudes from the bottom of the main housing. Thus, when the cleaning robot 10 moves over a cleaning surface, it can clean the surface using the cleaning mechanism 100.

[0056] The cleaning surfaces here include, but are not limited to, floors, and can also be other platform surfaces or furniture surfaces that need cleaning. It is worth noting that the shape of the main unit's casing is not limited in principle, as long as it can support the cleaning mechanism 100 and other components of the cleaning robot 10. Optionally, the main unit's casing can be a hollow three-dimensional structure, such as a hollow cylinder or polyhedron.

[0057] Optionally, the cleaning mechanism 100 includes a mop 132, and the cleaning robot 10 also includes a water tank (not shown) and a water supply pipe (not shown). The water supply pipe connects the water tank and the mop 132. The water tank is used to store water or other types of cleaning media. Water in the water tank can flow to the mop 132 through the water supply pipe, so that the cleaning mechanism 100 can wet mop the cleaning surface, improving the cleaning effect of the cleaning surface.

[0058] Optionally, a power supply component (not shown) is provided in the main housing. This power supply component is electrically connected to the cleaning mechanism 100 to supply power to the cleaning mechanism 100, enabling it to heat up after being powered on. Optionally, the power supply component is a lithium battery or the like. Optionally, the cleaning robot 10 also includes drive wheels (not shown), which are rotatably mounted on the bottom of the main housing and enable the cleaning robot 10 to move forward and backward.

[0059] Optionally, the cleaning robot 10 also includes a drive mechanism (not shown), which is the power source for the cleaning mechanism 100. The drive mechanism can be connected to the cleaning mechanism 100 and drive the cleaning mechanism 100 to rotate, so that the cleaning mechanism 100 can clean the surface. The connection between the drive mechanism and the cleaning mechanism 100 can be direct or indirect. Optionally, the cleaning robot 10 also includes a main control board (not shown), which is electrically connected to the components in the cleaning robot 10 that need to be controlled, such as the cleaning mechanism 100, the drive mechanism, and the drive wheels, to realize the control of each component.

[0060] It should be noted that the cleaning robot 10 also includes a cleaning component (not shown), a dust box (not shown), and other structures. The cleaning component is rotatably mounted on the bottom of the main unit housing and is used to clean dust, debris, etc., from the cleaning surface and collect them into the dust box. The focus of this application is on the cooperation between the cleaning mechanism 100 and the power supply and drive mechanism in the cleaning robot 10. Other structures of the cleaning robot 10 are not the focus of this application and will not be described in detail below.

[0061] See Figure 1 and Figure 2 In one embodiment, the cleaning mechanism 100 includes a fixed base 110, a connecting base 120, a cloth tray assembly 130, a heating element 140, and a conductive element 150. The fixed base 110 is disposed on the main unit housing. The connecting base 120 is connected to the output end of the drive mechanism and rotates with the output end. The cloth tray assembly 130 is disposed at the end of the connecting base 120 away from the fixed base 110. The heating element 140 is disposed on the cloth tray assembly 130 and is used to heat the cloth tray assembly 130. The conductive component 150 includes a first electrical contact 151, a second electrical contact 152, and a third electrical contact 153. The first electrical contact 151 is disposed on the main unit housing and is electrically connected to the power supply element. The second electrical contact 152 is disposed on the fixed base 110 and is electrically connected to the first electrical contact 151. The third electrical contact 153 is disposed on the connecting base 120 and the wiping tray assembly 130 and is rotatably electrically connected to the second electrical contact 152. The third electrical contact 153 is also electrically connected to the heating element 140 to supply power to the heating element 140.

[0062] The fixed base 110 is a fixed component of the cleaning mechanism 100, the connecting base 120 is a rotating component of the cleaning mechanism 100, and the mop tray assembly 130 is a component of the cleaning mechanism 100 that performs cleaning. The fixed base 110 is fixedly installed on the main unit housing, and the output end of the drive mechanism is the output sleeve 200. The fixed base 110 and the connecting base 120 are located in the output sleeve 200 of the drive mechanism. The connecting base 120 is connected to the output sleeve 200. The mop tray assembly 130 is located on the side of the connecting base 120 away from the fixed base 110. Furthermore, the connecting base 120 is also connected to the drive mechanism. The drive mechanism drives the connecting base 120 to rotate the mop tray assembly 130 around the central axis O of the fixed base 110, so that the mop tray assembly 130 can clean the cleaning surface.

[0063] The fixed seat 110 and the connecting seat 120 form the non-rotating and rotating areas of the cleaning mechanism 100. The fixed seat 110, being in the non-rotating area, remains stationary, while the connecting seat 120, being in the rotating area, can rotate relative to the fixed seat 110, allowing the connecting seat 120 to drive the cloth tray assembly 130 to rotate synchronously. The drive mechanism is fitted onto the connecting seat 120 via an output sleeve 200, thus driving the rotation of the connecting seat 120. It is understood that the output sleeve 200 can be directly the output end of the drive mechanism, allowing the connecting seat 120 to be directly connected to the output end of the drive mechanism. Of course, the output sleeve 200 and the output end of the drive mechanism are independent of each other, with the output sleeve 200 directly connected to the output end of the drive mechanism.

[0064] A heating element 140 is disposed on the mop tray assembly 130 and can rotate synchronously with the mop tray assembly 130. One end of the conductive component 150 can be electrically connected to the power supply element of the cleaning robot 10, and the other end is electrically connected to the heating element 140. The power supply element can supply power to the heating element 140 through the conductive component 150. After being energized, the heating element 140 can generate heat to heat the mop tray assembly 130. In this way, the heated mop tray assembly 130 can clean stubborn stains such as oil stains on the cleaning surface, improving the cleaning effect and efficiency.

[0065] Specifically, the conductive component 150 includes a first electrical contact 151, a second electrical contact 152, and a third electrical contact 153. The first electrical contact 151 is disposed in the main unit housing and electrically connected to the power supply element. The second electrical contact 152 is disposed in the fixing base 110 and electrically connected to the first electrical contact 151. The third electrical contact 153 is disposed in the connecting base 120 and the cloth tray assembly 130. The third electrical contact 153 is rotatably electrically connected to the second electrical contact 152 and electrically connected to the heating element 140. Thus, after the cleaning mechanism 100 is installed in the main unit housing, the second electrical contact 152 can be electrically connected to the power supply element of the cleaning robot 10 through the first electrical contact 151. At this time, the power supply element, the first electrical contact 151, the second electrical contact 152, the third electrical contact 153, and the heating element 140 are electrically connected to form a power supply circuit.

[0066] The third electrical contact 153 is electrically connected to the circuitry in the main unit casing via the second electrical contact 152 and the first electrical contact 151, enabling conductive isolation between the third electrical contact 153 and the power supply component. The power supply component typically operates at low voltage, ensuring high safety. Optionally, the first electrical contact 151 can be directly electrically connected to the power supply component. Alternatively, the first electrical contact 151 and the power supply component can be indirectly connected, for example, through other conductive components. When heating the cloth tray assembly 130 is required, the power supply component can supply power to the heating element 140 via the first electrical contact 151, the second electrical contact 152, and the third electrical contact 153, allowing the heating element 140 to heat the cloth tray assembly 130 after being energized.

[0067] Furthermore, the fixed base 110 and the connecting base 120 form the non-rotating area and the rotating area of ​​the cleaning mechanism 100. The third electrical contact 153 is integrated in the connecting base 120 and the cloth tray assembly 130. In this way, the third electrical contact 153 can rotate synchronously with the connecting base 120 and the cloth tray assembly 130. In addition, the third electrical contact 153 is rotatably electrically connected to the second electrical contact 152. Through the rotational cooperation between the connecting base 120 and the fixed base 110, the second electrical contact 152 can supply power to the rotating third electrical contact 153. This allows the cleaning mechanism 100 to achieve a combination of a stationary non-rotating area and an active rotating area, thereby solving the power supply problem of the rotating cloth tray assembly 130. This enables the cleaning mechanism 100 to stably and safely heat the cloth tray assembly 130 during dynamic cleaning.

[0068] This application uses electricity to directly heat the wiping tray assembly 130, eliminating the need to heat and transport hot water through a base station to heat the wiping tray assembly 130, and also eliminating the need to heat the water in the water tank in the host casing. This abandons the traditional indirect heating mode of "heating water first and then using water to transfer heat", eliminating the heat capacity of the intermediate medium and the heat loss of the pipeline, improving energy utilization, reducing energy consumption and improving thermal efficiency when reaching the same cleaning temperature, and has the characteristics of energy saving and environmental protection.

[0069] Furthermore, the heating element 140 can directly heat the cloth tray assembly 130, which has low thermal inertia and can reach the set temperature in a short time, achieving "instant heating" and improving the immediacy of cleaning response. At the same time, after the heating element 140 heats the cloth tray assembly 130, it can maintain a high and stable working temperature, effectively softening stubborn dirt such as oil and sugar stains on the cleaning surface. Combined with mechanical wiping, it greatly improves the cleanliness of a single cleaning.

[0070] The cleaning robot 10 in the above embodiment supplies power to the heating element 140 via the first electrical contact 151, the second electrical contact 152, and the third electrical contact 153 to directly heat the mop tray assembly 130. This eliminates the heat loss from the intermediate medium and pipelines, improving energy utilization. Furthermore, the mop tray assembly 130 reaches the set temperature quickly, achieving instant heating and enhancing the immediacy of the cleaning response. This allows the mop tray assembly 130 to effectively clean stubborn stains on surfaces, improving the cleanliness of a single cleaning cycle. Simultaneously, the rotatable electrical connection between the second electrical contact 152 and the third electrical contact 153 prevents the wires in the third electrical contact 153 from becoming entangled during rotation. This ensures that the second electrical contact 152 stably supplies power to the heating element 140 through the third electrical contact 153, guaranteeing the stability and safety of heating the mop tray assembly 130 during rotation.

[0071] Optionally, the connecting seat 120 is rotatably disposed on the fixed seat 110. The fixed seat 110 provides rotational support for the connecting seat 120 to ensure the smooth rotation of the connecting seat 120. For example, a bearing can be provided between the connecting seat 120 and the fixed seat 110 for rotational support. Of course, in other embodiments, the connecting seat 120 can also be separated from the fixed seat 110. That is, the connecting seat 120 and the fixed seat 110 are not connected, there is no connection between the connecting seat 120 and the fixed seat 110, and the connecting seat 120 is supported and mounted on the main unit housing by the output sleeve 200 of the drive mechanism.

[0072] See Figure 1 and Figure 2 In one embodiment, the outer diameter of the connecting seat 120 is larger than the outer diameter of the fixed seat 110. The outer wall of the connecting seat 120 fits against the inner wall of the output sleeve 200 and rotates synchronously with the drive mechanism relative to the fixed seat 110. It is understood that because the second electrical contact 152 in the fixed seat 110 and the third electrical contact 153 in the connecting seat 120 are rotatably electrically connected, the fixed seat 110 and the connecting seat 120 need to be located together in the output sleeve 200. To ensure that the drive mechanism only drives the connecting seat 120 to rotate and not the fixed seat 110, this application limits the outer diameter of the connecting seat 120 to be smaller than the outer diameter of the fixed seat 110.

[0073] In this way, when the drive mechanism rotates, it can drive the connecting seat 120 to rotate relative to the fixed seat 110, and keep the second electrical contact 152 stationary while the third electrical contact 153 rotates synchronously, realizing the rotatable connection between the second electrical contact 152 and the third electrical contact 153. At the same time, it can also ensure the reliability of the electrical connection between the second electrical contact 152 and the first electrical contact 151, so as to solve the power supply problem of the rotating cloth tray assembly 130, and enable the cleaning mechanism 100 to stably and safely heat the cloth tray assembly 130 during the dynamic cleaning process.

[0074] In one embodiment, the first electrical contact 151 extends through the output sleeve 200 and is fixed to the main unit housing. The first electrical contact 151 fixes the fixing base 110 to the main unit housing through the second electrical contact 152. That is, after the fixing base 110 is located inside the output sleeve 200, there is no fixed connection between the fixing base 110 and the output sleeve 200. The fixing base 110 is fixed to the main unit housing by the cooperation of the second electrical contact 152 and the first electrical contact 151, so that the output sleeve 200 can rotate relative to the fixing base 110.

[0075] Of course, in other embodiments, the top of the output sleeve 200 is provided with a through mounting hole, and the mounting base 110 is fixedly connected to the main unit housing through the mounting hole. That is, the top of the output sleeve 200 is an open structure, and the mounting hole formed by this open structure is a connection channel between the mounting base 110 and the main unit housing. The mounting base 110 can be directly connected to the main unit housing, or it can be connected to the main unit housing through an adapter such as a bracket, so that the output sleeve 200 can rotate relative to the mounting base 110.

[0076] In one embodiment, the cleaning mechanism 100 further includes a support bearing. The inner ring of the support bearing is fitted onto the fixed seat 110, and the outer ring of the support bearing is connected to the inner wall of the output sleeve 200, allowing the output sleeve 200 to rotate relative to the fixed seat 110. The support bearing provides rotational support to fix the fixed seat 110 to the output sleeve 200. In other words, the fixed seat 110 can also be mounted to the output sleeve 200 via the support bearing, and then mounted to the main unit housing via the output sleeve 200.

[0077] When the output sleeve 200 rotates, it drives the outer ring of the support bearing to rotate synchronously. The outer ring rotates relative to the inner ring, meaning that while the output sleeve 200 drives the outer ring to rotate, the inner ring remains stationary with respect to the fixed seat 110, preventing the fixed seat 110 from rotating with the output sleeve 200. Simultaneously, the rotation of the output sleeve 200 drives the connecting seat 120 to rotate relative to the fixed seat 110, thus enabling the cleaning mechanism 100 to combine its non-rotating and rotating areas.

[0078] Furthermore, after the fixed base 110 is supported to the output sleeve 200 by the support bearing, the fixed base 110 does not need to be indirectly connected to the main unit housing. In this case, the support bearing can stably support the fixed base 110. Of course, after the fixed base 110 is supported to the output sleeve 200 by the support bearing, the fixed base 110 can also be indirectly fixed to the main unit housing through the cooperation of the second electrical contact 152 and the first electrical contact 151, or indirectly fixed to the main unit housing through the mounting hole of the output sleeve 200. In this case, the fixed base 110 can be dually supported, further improving the reliability of the connection between the fixed base 110 and the main unit housing.

[0079] See Figure 1 and Figure 2 In one embodiment, the second electrical contact 152 has a first end 1521 and a second end 1522 opposite to each other, and the third electrical contact 153 has a third end 1531 and a fourth end 1532 opposite to each other. The second electrical contact 152 is electrically connected to the first electrical contact 151 through the first end 1521, and the third electrical contact 153 is rotatably electrically connected to the second end 1522 through the third end 1531, and is electrically connected to the heating element 140 through the fourth end 1532.

[0080] When the cleaning tray assembly 130 is rotatably mounted on the fixed base 110, the third end 1531 of the third electrical contact 153 is rotatably electrically connected to the second end 1522 of the second electrical contact 152. Thus, when the connecting base 120 rotates relative to the fixed base 110, the third electrical contact 153 can rotate relative to the second electrical contact 152 through the rotatable connection between its third end 1531 and its second end 1522. Simultaneously, a conductive connection is also achieved between the third electrical contact 153 and the second electrical contact 152. The first electrical contact 151 is electrically connected to the power supply element. When the cleaning mechanism 100 is installed on the main unit housing, the second electrical contact 152 is electrically connected to the first electrical contact 151 through its first end 1521, so that the second electrical contact 152 is electrically connected to the power supply element through the first electrical contact 151.

[0081] Thus, the power supply element is electrically connected to the second electrical contact 152 via the first electrical contact 151 and the first end 1521, and then electrically connected to the third electrical contact 153 via the rotatable electrical connection between the third end 1531 and the second end 1522. Finally, it is electrically connected to the heating element 140 via the fourth end 1532. In this way, the power supply element transmits electrical energy through the first electrical contact 151, the second electrical contact 152, and the third electrical contact 153 to heat the heating element 140.

[0082] See Figure 1 and Figure 2In one embodiment, the second electrical contact 152 is embedded in the fixing base 110, and the second electrical contact 152 extends out of both ends of the fixing base 110. The second electrical contact 152 is fixedly disposed in the fixing base 110 to prevent the position of the second electrical contact 152 in the fixing base 110 from shifting, thus ensuring the conductivity and operational reliability of the second electrical contact 152. Moreover, the first end 1521 and the second end 1522 of the second electrical contact 152 are exposed at both ends of the fixing base 110. In this way, the second electrical contact 152 can be electrically connected to the first electrical contact 151 through the first end 1521, and to the third electrical contact 153 through the second end 1522, thereby realizing effective power transmission.

[0083] See Figure 1 and Figure 2 In one embodiment, the second electrical contact 152 is a metal conductive sheet. The metal conductive sheet is integrated into the mounting base 110, with both ends protruding from the mounting base 110 for electrical connection with the first electrical contact 151 and the third electrical contact 153, thereby achieving effective power transmission. Of course, in other embodiments, the second electrical contact 152 may also be a conductive wire or other components capable of conducting electricity.

[0084] See Figure 1 and Figure 2 In one embodiment, the first end 1521 of the second electrical contact 152 may be provided with a conductive adsorption element, which is adsorbed and connected to the first electrical contact 151. After the conductive adsorption element is provided at the first end 1521 of the second electrical contact 152, the conductive adsorption element can be adsorbed onto the first electrical contact 151, realizing a reliable connection between the second electrical contact 152 and the first electrical contact 151, while also ensuring the conductivity between the second electrical contact 152 and the first electrical contact 151.

[0085] See Figure 1 and Figure 2 In one embodiment, the first electrical contact 151 is disposed on the main unit casing and at least partially exposed to the main unit casing for electrical connection with the second electrical contact 152. That is, after the first electrical contact 151 is disposed on the main unit casing, one end of the first electrical contact 151 protrudes towards the second electrical contact 152 for conductive connection. This facilitates the conductive connection between the first electrical contact 151 and the second electrical contact 152, thereby enabling efficient transmission of electrical energy.

[0086] See Figure 1 and Figure 2In one embodiment, the first electrical contact 151 is a metal spring pin or a metal spring sheet. The first electrical contact 151, being a metal spring pin or a metal spring sheet, can contact the first end 1521 of the second electrical contact 152, thereby achieving an electrical connection between the first electrical contact 151 and the second electrical contact 152. Of course, in other embodiments, the first electrical contact 151 can also be any other component capable of achieving an electrical connection with the power supply element and the second electrical contact 152.

[0087] See Figure 1 and Figure 2 In one embodiment, there are two first electrical contacts 151, which are spaced apart and connected to the positive and negative terminals of the power supply element, respectively. The two first electrical contacts 151 are also connected to a second electrical contact 152, so that the power supply element, the first electrical contacts 151, the second electrical contacts 152, the third electrical contact 153, and the heating element 140 form a conductive circuit.

[0088] See Figure 1 and Figure 2 In one embodiment, there are two second electrical contacts 152, which are spaced apart in the fixing base 110. The two second electrical contacts 152 are electrically connected to the two first electrical contacts 151 respectively, and are also connected to the third electrical contact 153 respectively, to form a conductive circuit.

[0089] See Figure 1 and Figure 2 In one embodiment, the conductive component 150 further includes a rotating conductive element 154, which is at least partially located between the fixed base 110 and the connecting base 120. The rotating conductive element 154 is rotatably electrically connected to the second electrical contact 152 and the third electrical contact 153, so that the third electrical contact 153 can rotate relative to the second electrical contact 152.

[0090] The rotating conductive element 154 is located between the fixed base 110 and the connecting base 120. The second end 1522 of the second electrical contact 152 is electrically connected to the rotating conductive element 154, and the third end 1531 of the third electrical contact 153 can be electrically connected to the rotating conductive element 154. When the connecting base 120 rotates, the rotating conductive element 154 enables the third electrical contact 153 to rotate relative to the second electrical contact 152. Consequently, the third electrical contact 153 can rotate synchronously with the connecting base 120 and the cloth tray assembly 130 to supply power to the heating element 140.

[0091] The second electrical contact 152 and the third electrical contact 153 are rotatably connected by a rotating conductive element 154. This allows the third electrical contact 153 to rotate smoothly around the central axis O. When the third electrical contact 153 rotates, the wires within it will not become tangled or stretched; instead, they will rotate synchronously with the rotating conductive element 154 and the connecting seat 120, ensuring that the third electrical contact 153 remains installed in the connecting seat 120. This ensures the performance of the third electrical contact 153 and prevents damage caused by tangling during rotation.

[0092] In other words, the rotating conductive component 154 enables a rotatable connection between the second electrical contact 152 and the third electrical contact 153, while also ensuring the conductivity between the second electrical contact 152 and the third electrical contact 153. This allows the second electrical contact 152 to be stably and safely connected to the rotating third electrical contact 153, solving the technical problem of continuous power supply to the rotating component. This enables the second electrical contact 152 and the third electrical contact 153 to stably and safely heat the cloth tray assembly 130 through the heating component 140 during dynamic cleaning.

[0093] See Figure 1 and Figure 2 In one embodiment of this application, a rotating conductive member 154 is disposed at one end of the connecting seat 120 facing the fixed seat 110, and rotates with the connecting seat 120 relative to the fixed seat 110. One end of the second electrical contact 152 abuts against the rotatable rotating conductive member 154. The rotating conductive member 154 is electrically connected to the third electrical contact 153, and rotates with the connecting seat 120 relative to the fixed seat 110 and the second electrical contact 152.

[0094] The rotating conductive element 154 is fixed to the top of the connecting seat 120 and is located between the fixed seat 110 and the connecting seat 120. When the drive mechanism drives the connecting seat 120 to rotate through the output sleeve 200, the connecting seat 120 can simultaneously drive the rotating conductive element 154 to rotate synchronously. Furthermore, the second end 1522 of the second contact 152 can extend toward the rotating conductive element 154 and maintain conductive contact with the rotating conductive element 154.

[0095] In other words, during the rotation of the rotating conductive member 154, the second end 1522 of the second electrical contact 152 remains in contact with the rotating conductive member 154, and the rotating conductive member 154 and the second electrical contact 152 maintain a rotatable electrical connection. Furthermore, the rotating conductive member 154 is also electrically connected to the third end 1531 of the third electrical contact 153, thus achieving a conductive connection between the rotating third electrical contact 153 and the stationary second electrical contact 152.

[0096] In this way, when the connector 120 drives the rotating conductive element 154 and the third electrical contact 153 to rotate, the rotating conductive element 154 can maintain conductive contact with the second electrical contact 152 during rotation, while also allowing the third electrical contact 153 to rotate smoothly around the central axis O. Furthermore, when the third electrical contact 153 rotates, the wires in the third electrical contact 153 will not become tangled or stretched, but will rotate synchronously with the rotating conductive element 154 and the connector 120, so that the third electrical contact 153 remains installed in the connector 120, thereby ensuring the performance of the third electrical contact 153 and avoiding damage caused by tangling during rotation.

[0097] It should be noted that, in this embodiment, the structure and type of the rotating conductive element 154 are not limited in principle, as long as the rotating conductive element 154 can be fixed to the connecting seat 120 and maintain contact with the second end 1522 of the second electrical contact 152 during rotation, so as to achieve the conductive connection between the rotating third electrical contact 153 and the stationary second electrical contact 152.

[0098] In another embodiment of this application, the rotating conductive member 154 includes a stationary portion and a rotating portion. The stationary portion is disposed on the fixed base 110 and electrically connected to the second electrical contact 152. The rotating portion is disposed on the connecting base 120 and electrically connected to the third electrical contact 153. The stationary portion and the rotating portion are rotatably electrically connected so that the rotating portion and the third electrical contact 153 rotate with the connecting base 120 relative to the fixed base 110 and the second electrical contact 152.

[0099] The stationary portion and the rotating portion form the main structure of the rotating conductive element 154. The stationary portion and the rotating portion are rotatably connected, meaning that the rotating portion can rotate relative to the stationary portion, and the rotating portion is also electrically connected to the stationary portion. The stationary portion is disposed in the fixed base 110 and remains stationary with the fixed base 110. The stationary portion can be electrically connected to the second end 1522 of the second electrical contact 152. The rotating portion is disposed in the connecting base 120 and rotates synchronously with the connecting base 120 relative to the fixed base 110 and the stationary portion. The rotating portion is electrically connected to the third end 1531 of the third electrical contact 153.

[0100] In other words, the rotating part can rotate relative to the stationary part. When the connecting seat 120 drives the rotating part to rotate, the stationary part remains stationary and maintains a conductive connection with the second electrical contact 152. Simultaneously, it also maintains a conductive connection with the rotating part, allowing the rotating part to maintain a rotatable electrical connection with the second electrical contact 152 through the stationary part. Furthermore, the rotating part is also electrically connected to the third end 1531 of the third electrical contact 153, achieving a conductive connection between the rotating third electrical contact 153 and the stationary second electrical contact 152.

[0101] Thus, the stationary and rotating parts enable a conductive connection between the second electrical contact 152 and the rotating third electrical contact 153. When the connecting base 120 drives the rotating part and the third electrical contact 153 to rotate, the rotating part maintains conductive contact with the second electrical contact 152 through the stationary part, while simultaneously allowing the third electrical contact 153 to rotate smoothly around the central axis O. Furthermore, when the third electrical contact 153 rotates, the wires within it will not become tangled or stretched, but will rotate synchronously with the rotating part and the connecting base 120, ensuring that the third electrical contact 153 remains installed in the connecting base 120. This guarantees the performance of the third electrical contact 153 and prevents damage caused by tangling during rotation.

[0102] It should be noted that, in this embodiment, the structural form and type of the stationary part and the rotating part are not limited in principle. As long as the stationary part can be fixed to the fixing base 110 and the rotating part can be fixed to the connecting base 120, and the stationary part and the rotating part are rotatably electrically connected, the conductive connection between the rotating third electrical contact 153 and the stationary second electrical contact 152 can be achieved.

[0103] See Figure 1 and Figure 2 In one embodiment, there are two third electrical contacts 153. Each third electrical contact 153 is electrically connected to a second electrical contact 152. The two third electrical contacts 153 are simultaneously connected to the second electrical contacts 152, so that the power supply element, the first electrical contact 151, the second electrical contact 152, the third electrical contact 153 and the heating element 140 form a conductive circuit, ensuring that the heating element 140 can generate heat after being energized, so as to heat the cloth tray assembly 130.

[0104] See Figure 1 and Figure 2 In one embodiment, the cloth tray assembly 130 includes a mounting bracket 131 and a cloth 132. The mounting bracket 131 is located at the end of the connecting seat 120 away from the fixed seat 110, and the cloth 132 is located on the mounting bracket 131. The heating element 140 is located between the cloth 132 and the mounting bracket 131. The connecting seat 120 is located on the side of the mounting bracket 131 facing the fixed seat 110 and is rotatably mounted on the fixed seat 110. The cloth 132 is mounted on the surface of the mounting bracket 131 opposite to the connecting seat 120. Furthermore, the connecting seat 120 is also located in the output sleeve 200. The driving mechanism can drive the output sleeve 200 to move the connecting seat 120, so that the connecting seat 120 drives the mounting bracket 131 to rotate, and then the mounting bracket 131 can drive the cloth 132 to rotate, so that the cloth 132 can clean the cleaning surface.

[0105] The heating element 140 is disposed on the surface of the mounting bracket 131 opposite to the connecting base 120, and is located between the mounting bracket 131 and the mop 132. In this way, the heating element 140 can generate heat when it is powered on, and the heat can be directly conducted to the mop 132, causing the mop 132 to heat up rapidly. Thus, the mop 132 can wipe the cleaning surface at a higher temperature during mopping, achieving effective dissolution and cleaning of stubborn stains.

[0106] It is worth noting that the shape of the mounting bracket 131 is not limited in principle, as long as the shape of the mounting bracket 131 can support the wiping cloth 132 and clean the cleaning surface. Optionally, the mounting bracket 131 is circular. Of course, in other embodiments, the mounting bracket 131 may also be elliptical, polygonal, or other shapes.

[0107] Optionally, the outer diameter of the connecting seat 120 is smaller than the outer diameter of the mounting bracket 131. This reduces the size of the output sleeve 200, facilitating the connection between the connecting seat 120 and the output sleeve 200. Optionally, the cross-sectional shape of the connecting seat 120 can be polygonal, flat, D-shaped, etc., to facilitate connection with the output sleeve 200, thereby enabling synchronous rotation of the connecting seat 120 and the output sleeve 200. Of course, the connecting seat 120 and the output sleeve 200 can also be connected in a splined manner.

[0108] See Figure 1 and Figure 2 In one embodiment, the cloth 132 is attached to or snapped onto the mounting bracket 131. The cloth 132 can be fixed to the mounting bracket 131 by Velcro, snap-fit, zipper, or other detachable means.

[0109] As a consumable, the rag 132 can be replaced individually, making maintenance convenient. The heating principle of the cleaning robot 10 for the rag 132 is highly versatile, and the type of cleaning robot 10 used in the cleaning mechanism 100 is not limited in principle. It can be applied to various rotating rag 132 structures of cleaning robots 10, including but not limited to circular rotating mops, double-disc rotating mops, etc., and has broad application prospects.

[0110] In one embodiment, the mounting bracket 131 is provided with a heat insulation layer. The heat insulation layer is disposed on the surface of the mounting bracket 131 facing the heating element 140. In this way, the heat insulation layer can minimize the heat generated by the heating element 140 from being transferred to the mounting bracket 131, so that most of the heat is transferred to the cloth 132, minimizing heat dissipation through the mounting bracket 131, reducing energy consumption, and also preventing burns to the user.

[0111] Of course, in other embodiments, the mounting bracket 131 may also be made of heat-insulating material. The mounting bracket 131 made of heat-insulating material can minimize the heat generated by the heating element 140 from being transferred to the mounting bracket 131, so that most of the heat is transferred to the cloth 132, and heat dissipation through the mounting bracket 131 is minimized, thereby reducing energy consumption. At the same time, it can also prevent burns to the user.

[0112] See Figure 1 and Figure 2 In one embodiment, the heating element 140 is embedded in the surface of the mounting bracket 131 facing the cloth 132. This reduces the size of the heating element 140 in the thickness direction of the mounting bracket 131 without affecting the heating effect on the cloth 132, thereby reducing the overall height of the cleaning mechanism 100 and ensuring reliable fixation of the heating element 140. Alternatively, in other embodiments, the heating element 140 can be fitted against the surface of the mounting bracket 131 facing the cloth 132 to reduce the distance between the heating element 140 and the cloth 132, thus improving the heating effect on the cloth 132.

[0113] See Figure 1 and Figure 2 In one embodiment, the heating element 140 is a resistance heating wire or a resistance heating film. The resistance heating wire or resistance heating film is disposed on the surface of the mounting bracket 131 to heat the cloth 132. Of course, in other embodiments, the heating element 140 may also be other electrically heated components.

[0114] See Figure 1 and Figure 2 Figure 1 Figure 2 Figure 1 Figure 2 Figure 1 Figure 2 Figure 1 Figure 2 Figure 1 Figure 2 Figure 1 Figure 2 Figure 1 Figure 2 Figure 1 Figure 2 Figure 1 Figure 2 Figure 1 Figure 2 Figure 1 Figure 2 Figure 1 Figure 2 In one embodiment, the area of ​​the heating element 140 is less than or equal to the area of ​​the cloth 132 in contact with the cleaning surface. This ensures that the heating area of ​​the heating element 140 on the cloth 132 is uniformly heated, thereby ensuring the cleaning effect of the cloth 132 on stubborn stains.

[0115] In one embodiment, the cleaning robot 10 includes a cleaning mechanism 100. That is, the bottom of the cleaning robot 10 may only have one cleaning mechanism 100. This can also meet the cleaning needs of the cleaning robot 10.

[0116] In another embodiment, the cleaning robot 10 includes at least two cleaning mechanisms 100, which are spaced apart at the bottom of the main housing and rotate in the same or opposite directions. The spaced-apart arrangement of the cleaning mechanisms 10 at the bottom of the main housing increases the cleaning capability of the cleaning robot 10. Optionally, there are two cleaning mechanisms 100, symmetrically arranged. Of course, the number of cleaning mechanisms 100 can also be three or other numbers.

[0117] The working process of the cleaning mechanism 100 of this application is as follows: When the cleaning robot 10 starts the hot water mopping function, the main control board controls the power supply component to supply power. At this time, the electrical energy of the power supply component is conducted to the second electrical contact 152 through the first electrical contact 151. The second electrical contact 152 conducts electrical energy to the third electrical contact 153 through a rotatable and conductive connection between the third end 1531 and the second end 1522, and then to the heating component 140 through the third electrical contact 153. After the heating component 140 is powered on, it can generate heat, which is directly conducted to the mop 132 in close contact with it, causing the mop 132 to heat up rapidly. Thus, the mop 132 wipes the floor at a higher temperature during the mopping process, achieving effective dissolution and cleaning of stubborn stains.

[0118] This application also provides a cleaning system, including a base station and a cleaning robot 10 as described in any of the above embodiments. The cleaning robot 10 can drive into, out of, or dock at the base station. After driving out of the base station, the cleaning robot 10 can clean the surface. After driving into the base station, the cleaning robot 10 can dock at a designated location on the base station. The base station can provide the cleaning robot 10 with functional services such as charging, cleaning the cleaning cloth 132, and dust collection.

[0119] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0120] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
