[0033] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0034] The embodiment of the present application provides a cleaning device. The cleaning device may be a mopping robot, a sweeping and mopping robot, or a sweeping robot equipped with a mopping module. Here, the sweeping and mopping robot may mop the floor after sweeping the floor. In this way, the floor cleaned by the sweeping and mopping robot will be cleaner.

[0035] To see the structure of the cleaning equipment more clearly, please refer to Figure 1 , Figure 1 000 is a cross-sectional view of a cleaning device provided by an embodiment of the present application. The cleaning device 000 may include: a housing 100 , a mopping assembly 200 , and a heating assembly 500 .

[0036] Please refer to Figure 1 and Figure 2 , Figure 2 It is a structural schematic diagram of a cleaning device provided in an embodiment of the present application. The bottom surface of the shell 100 in the cleaning device 000 may have a first mounting groove K1 and a plurality of air outlets O. Here, the bottom surface of the shell 100 in the cleaning device 000 refers to: when the cleaning device 000 is placed on the ground and the ground is cleaned, the side of the shell 100 in the cleaning device 000 faces the ground. In this case, the plurality of air outlets O in the shell 100 can be connected to the outside world, and since the first mounting groove K1 and the plurality of air outlets O in the shell 100 are located on the bottom surface of the shell 100, therefore, when the cleaning device 000 cleans the ground, the first mounting groove K and the plurality of air outlets O located on the bottom surface of the shell 100 can be aligned with the ground.

[0037] The mopping assembly 200 in the cleaning device 000 can be installed in the first installation groove K1. Here, the cleaning device 000 can mop the floor.

[0038] During the operation of the cleaning device 000, the cleaning device 000 can be used to drive the mopping assembly 200 to move along the first installation slot K1 in a direction away from the multiple air outlets O. In this way, during the operation of the cleaning device 000 mopping the floor through the mopping assembly 200, the multiple air outlets O of the housing 100 can be aligned with the floor cleaned by the mopping assembly 200.

[0039] The housing 100 in the cleaning device 000 may have a ventilation passage P inside that is connected to a plurality of air outlets O.

[0040] It should be noted that during the process of mopping the floor by the mopping component 200 in the cleaning device 000, sewage will remain on the floor. After the mopping component 200 in the cleaning device 000 cleans the floor, the cleaning device 000 can promptly process the sewage remaining on the floor. For example, the cleaning device 000 can suck the sewage on the floor into the interior of the cleaning device 000 to take away the sewage remaining on the floor.

[0041] It should also be noted that during the operation of the cleaning device 000, there may be airflow in the ventilation channel P. Here, during the operation of the cleaning device 000 to suck the sewage remaining on the ground into the interior of the cleaning device 000, airflow may be generated in the ventilation channel P. Alternatively, during the operation of the heat dissipation component in the cleaning device 000, airflow may be generated in the ventilation channel P.

[0042] In the present application, after the mopping assembly 200 in the cleaning device 000 cleans the floor, the airflow in the ventilation channel P can be blown out through a plurality of air outlets O to blow toward the floor cleaned by the mopping assembly 200 .

[0043] The heating component 500 in the cleaning device 000 can be installed in the ventilation channel P in the shell 100, and the heating component 500 in the cleaning device 000 can be used to heat the airflow entering the ventilation channel P, and the heated airflow can be blown out from multiple air outlets O in the shell 100.

[0044] It should be noted that after the mopping component 200 in the cleaning device 000 cleans the ground, the cleaning device 000 cannot take away all the sewage remaining on the ground, and water stains will still remain on the ground. Here, since the heating component 500 in the cleaning device 000 can heat the airflow in the ventilation channel P, the heated airflow can be blown out from the multiple air outlets O of the housing 100, and these air outlets O can be aimed at the ground after being mopped by the mopping component 200. Therefore, the heated airflow blown out from the multiple air outlets O can dry the water stains remaining on the ground. To this end, the cleaning device 000 can not only mop the ground, but also absorb and dry the sewage remaining on the ground during the mopping process, so that the ground cleaned by the cleaning device 000 is relatively dry, which effectively improves the effect of the cleaning device 000 on cleaning the ground.

[0045] In summary, the present application provides a cleaning device. The cleaning device may include: a shell, a mopping component and a heating component. During the process of mopping the floor by the mopping component in the cleaning device, the airflow in the ventilation duct may be heated by the heating component in the ventilation duct. In this way, the airflow blown out from multiple air outlets through the ventilation channel is the heated airflow. These heated airflows can dry the water stains remaining on the ground. To this end, the cleaning device can not only mop the floor, but also absorb and dry the sewage remaining on the ground during the mopping process, so that the floor cleaned by the cleaning device is relatively dry, which effectively improves the effect of the cleaning device on cleaning the floor.

[0046] Optional, please refer to Figure 3 , Figure 3It is a partial enlarged view of a cleaning device provided by an embodiment of the present application. The multiple air outlets O in the housing 100 may include: multiple first air outlets O1 and multiple second air outlets O2. The multiple first air outlets O1 in the housing 100 may be closer to the mopping assembly 200 relative to the multiple second air outlets O2 in the housing 100, and the opening area of ​​the first air outlet O1 may be larger than the opening area of ​​the second air outlet O2.

[0047] It should be noted that since the multiple first air outlets O1 in the shell 100 are closer to the mopping assembly 200 than the multiple second air outlets O2 in the shell 00, when the cleaning device 000 moves along the first mounting groove K1 in the direction away from the multiple air outlets O, the heated airflow blown out through the multiple first air outlets O1 in the shell 100 can first dry the floor for the first time, and then the heated airflow blown out through the multiple second air outlets O2 in the shell 100 can dry the floor for the second time.

[0048] In the present application, the opening area of ​​the first air outlet O1 in the shell 100 is relatively large, which makes the heated airflow blown out through the first air outlet O1 in the shell 100 more. In this way, the heated airflow blown out through the first air outlet O1 in the shell 100 can quickly dry the ground. It should be noted that the ground will still leave water marks after the heated airflow blown out through the first air outlet O1 in the shell 100 is quickly dried. In the present application, the opening area of ​​the second air outlet O2 in the shell 100 is relatively small, which makes the heated airflow blown out through the second air outlet O2 in the shell 100 a fine wind. In this way, the heated airflow blown out through the second air outlet O2 in the shell 100 can better dry the water marks remaining on the ground. In this way, the degree of dryness of the ground after being dried by the heated airflow blown out successively through the first air outlet O1 with a larger opening area and the second air outlet O2 with a smaller opening area in the shell 100 is relatively high, so that the cleaning device 000 has a better drying effect on the ground.

[0049] Optional, such as Figure 3As shown, the first air outlet O1 in the housing 100 may be strip-shaped, and the multiple first air outlets O1 in the housing 100 may be arranged in a plurality of rows in a direction away from the mopping assembly 200, and each row of the first air outlets O1 in the housing 100 may include at least one first air outlet O1; and / or, the second air outlet O2 in the housing 100 may be hole-shaped, and the multiple second air outlets O2 in the housing 100 may be arranged in a matrix, that is, the multiple second air outlets O2 in the housing 100 may be arranged in a plurality of rows and columns. In this way, it can be ensured that the opening area of ​​the first air outlet O1 in the housing 100 in the strip shape can be larger than the opening area of ​​the second air outlet O2 in the housing 100 in the hole shape. In this way, the heated airflow blown out through the multiple first air outlets O1 in the housing 100 can quickly dry the water stains remaining on the ground. Then, the water marks still remaining on the ground after being dried by the heated airflows blown out by the multiple first air outlets O1 in the shell 100 can be dried by the heated airflows blown out by the multiple second air outlets O2 in the shell 100 .

[0050] In this application, please refer to Figure 4 , Figure 4 It is a cross-sectional view of another cleaning device provided in an embodiment of the present application. The ventilation channel P in the cleaning device 000 may include: a first air duct P1 and a second air duct P2. The first end of the first air duct P1 may be communicated with a plurality of first air outlets O1, and the first end of the second air duct P2 may be communicated with a plurality of second air outlets O2. In this way, the heated airflow located in the ventilation channel P and converted by the heating component 500 can be divided into two parts. These two parts of the heated airflow can be blown out from the plurality of first air outlets O1 and the plurality of second air outlets O2 communicated with the second end of the fourth air duct P4 through the first end of the first air duct P1 and the second air duct P2 in the housing 100, respectively.

[0051] Optional, such as Figure 3 and Figure 4 , the ventilation area of ​​the first air duct P1 in the housing 100 may be smaller than the ventilation area of ​​the second air duct P2 in the housing 100. Here, the ventilation area of ​​the first air duct P1 in the housing 100 refers to: the cross-sectional area in the direction perpendicular to the extension of the first air duct P1. Correspondingly, the ventilation area of ​​the second air duct P2 in the housing 100 refers to: the cross-sectional area in the direction perpendicular to the extension of the second air duct P2.

[0052] In this way, the ventilation area of ​​the first air duct P1 in the housing 100 is relatively small, so that after the heated airflow enters the first air duct P1 from the ventilation air duct P in the housing 100, the flow rate of the heated airflow is relatively large, so that the heated airflow blown out from the multiple first air outlets O1 connected to the first air duct P1 can quickly dry the water stains on the ground. In addition, the ventilation area of ​​the second air duct P2 in the housing 100 is relatively large, so that the number of second air outlets O2 in the housing 100 connected to the second air duct P2 is relatively large, and thus the heated airflow blown out from the multiple second air outlets O2 through the second air duct P2 in the housing 100 can dry the water stains on the ground over a large area.

[0053] In this application, if Figure 4 As shown, the cleaning device 000 may further include: a partition 700 fixed between the first air duct P1 and the second air duct P2 in the housing 100. The partition 700 in the cleaning device 000 may divide the heated airflow blown out from the ventilation channel P in the housing 100 into two parts, so that the two parts of the heated airflow may enter the first air duct P1 and the second air duct P2 in the housing 100 respectively, and then be blown out from the first air outlet O1 connected to the second end of the first air duct P1 and the second air outlet O2 connected to the second end of the second air duct P2 respectively.

[0054] Optional, such as Figure 4 As shown, the cleaning device 000 may further include: a fan assembly 300 and a housing box 400 fixed inside the housing 100. The ventilation duct P may further include: a third duct P3 and a fourth duct P4. The first end of the third duct P3 may be communicated with the first mounting groove K1 of the housing 100, and the other end of the third duct P3 may be communicated with the housing box 400. The first end of the fourth duct P4 may be communicated with the housing box 400, and the second end of the fourth duct P4 may be communicated with the second ends of the first duct P1 and the second duct P2. Among them, the fan assembly 300 in the cleaning device 000 is used to form a negative pressure inside the housing box 400, and the heating assembly 500 in the cleaning device 000 may be installed in the fourth duct P4.

[0055] In the process of the mopping assembly 200 in the cleaning device 000 cleaning the ground, the fan assembly 300 in the cleaning device 000 can be made to work synchronously. Here, after the fan assembly 300 in the cleaning device 000 starts to work, a negative pressure can be formed in the container box 400, that is, the pressure inside the container box 400 in the cleaning device 000 can be less than the pressure of the external environment. In addition, since the container box 400 in the cleaning device 000 is connected to the second end of the third air duct P3 in the shell 100, and the first installation groove K connected to the first end of the third air duct P3 in the shell 100 is aligned with the ground. Therefore, after a negative pressure is formed in the container box 400, so that the pressure inside the container box 400 is less than the pressure of the external environment, the airflow in the external environment will enter the container box 400 after passing through the first installation groove K1 and the third air duct P3, and the airflow can carry the sewage remaining on the ground into the container box 400. To this end, after the fan assembly 300 in the cleaning device 000 starts to work, the sewage remaining on the ground can be sucked into the accommodating box 400 through the first installation groove K1 and the first air duct P1 in the shell 100.

[0056] In addition, since the accommodating box 400 is also connected to the second end of the fourth air duct P4, after the sewage is received by the accommodating box 400, the airflow in the third air duct P3 can enter the fourth air duct P4 through the accommodating box 400. And since the second end of the fourth air duct P4 is connected to the second end of the first air duct P1 and the second end of the second air duct P2, the airflow entering the fourth air duct P4 can be divided into two parts, and the two parts of the airflow can enter the first air duct P1 and the second air duct P2 respectively, and then blown out through the plurality of first air outlets O1 and the plurality of second air outlets O2 respectively.

[0057] Optional, please refer to Figure 5 , Figure 5 000 may further include: a scraper 800 fixed at the opening of the first end of the third air duct P3 in the housing 100. The scraper 800 in the cleaning device 000 may be fixed between the mopping assembly 200 and the plurality of air outlets O in the housing 100.

[0058] It should be noted that the mopping assembly 200 and the scraper 800 in the cleaning device 000 can contact the ground at the same time. In this way, during the working process of the cleaning device 000, the mopping assembly 200 in the cleaning device 000 can mop the ground. After the mopping assembly 200 in the cleaning device 000 mops the ground, a lot of sewage will remain on the ground. Since the cleaning device 000 moves in the direction away from the multiple air outlets O along the first mounting groove K1, the scraper 800 located behind the mopping assembly 200 and in contact with the ground in the moving direction of the cleaning device 000 can collect sewage at the connection between the first end of the third air duct P3 in the housing 100 and the first mounting groove K1. In this way, under the action of the fan assembly 300 in the cleaning device 000, the sewage remaining on the ground can pass through the first mounting groove K1 and the first air duct P1 in the housing 100 and enter the accommodating box 400.

[0059] In this application, if Figure 5 As shown, the accommodating box 400 in the cleaning device 000 may have a first opening S1 and a second opening S2 that are arranged opposite to each other. The accommodating box 400 in the cleaning device 000 may be connected to the second end of the third air duct P3 in the housing 100 through the first opening S1, and the accommodating box 400 in the cleaning device 000 may be connected to the first end of the fourth air duct P4 in the housing 100 through the second opening S2. In this way, after the fan assembly 300 in the cleaning device 000 starts working, the airflow generated in the external environment passes through the first mounting groove K1 and the third air duct P3 in the housing 100, and then enters the accommodating box 400 through the first opening S1 of the accommodating box 400. Then, the airflow entering the accommodating box 400 may enter the fourth air duct P4 through the second opening S2 of the accommodating box 400.

[0060] In this application, if Figure 5 As shown, the fan assembly 300 in the cleaning device 000 can be located in the fourth air duct P4 in the housing 100, and the fan assembly 300 in the cleaning device 000 can be distributed at the second opening S2 of the accommodating box 400. In this way, the fan assembly 300 in the cleaning device 000 can be close to the second opening S2 of the accommodating box 400, so that after the fan assembly 300 in the cleaning device 000 starts to work, the accommodating box 400 in the cleaning device 000 can have a greater negative pressure, so that more sewage can be sucked into the accommodating box 400.

[0061] In this application, if Figure 4As shown, the heating assembly 500 in the cleaning device 000 can be closer to the multiple air outlets O in the housing 100 relative to the fan assembly 300. This allows the airflow entering the fourth air duct P4 in the housing 100 to be heated by the heating assembly 500 in the cleaning device 000, and then the airflow blown out from the multiple air outlets O in the housing 100 can all be heated airflow.

[0062] In this application, please refer to Figure 6 , Figure 6 It is a structural schematic diagram of another cleaning device provided by an embodiment of the present application. The cleaning device 000 may also include: a moving component 900 connected to the bottom surface of the housing 100. The moving component 900 in the cleaning device 000 may be used to drive the cleaning device 000 to move as a whole along the direction in which the first mounting groove K1 is away from the multiple air outlets O in the housing 100. Here, the direction in which the first mounting groove K1 is away from the multiple air outlets O in the housing 100 is also the direction in which the mopping component 200 is away from the multiple air outlets O.

[0063] It should be noted that when the cleaning device 000 is a sweeping and mopping robot, the housing 100 in the cleaning device 000 may also have a second mounting slot K2. The second mounting slot K2 in the housing 100 may be used to mount a sweeping brush 600. The sweeping brush 600 in the cleaning device 000 may sweep the floor to remove garbage.

[0064] It should also be noted that the direction in which the mopping assembly 200 in the cleaning device 000 is away from the multiple air outlets O in the housing 100 is also the direction in which the sweeping brush 600 is away from the mopping assembly 200. In this way, during the operation of the cleaning device 000, the sweeping brush 600 in the cleaning device 000 first cleans the floor, and then the mopping assembly 200 in the cleaning device 000 mops the floor. In this way, the floor cleaned by the cleaning device 000 will be cleaner.

[0065] In summary, the present application provides a cleaning device. The cleaning device may include: a shell, a mopping component and a heating component. During the process of mopping the floor by the mopping component in the cleaning device, the airflow in the ventilation duct may be heated by the heating component in the ventilation duct. In this way, the airflow blown out from multiple air outlets through the ventilation channel is the heated airflow. These heated airflows can dry the water stains remaining on the ground. To this end, the cleaning device can not only mop the floor, but also absorb and dry the sewage remaining on the ground during the mopping process, so that the floor cleaned by the cleaning device is relatively dry, which effectively improves the effect of the cleaning device on cleaning the floor.

[0066] In the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.

[0067] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
