[0034] As mentioned in the background, the existing sweeping robot brings dust and garbage into the roller brush cavity by the rotation of the roller brush, and then the dust and garbage are sucked into the dust box. However, due to the adsorption of dust and garbage, dust and garbage are easily left at positions deviating from the dust suction port in the roller brush cavity during the sweeping process of the sweeping robot, which reduces the dust removal efficiency of the sweeping robot. Therefore, the inventors of the present application have designed a new type of cleaning device which can solve the problem that dust and garbage are easily left at positions deviating from the dust suction port in the roller brush cavity in the prior art, resulting in low dust removal efficiency of the sweeping robot. The cleaning device of the present application will be described in detail below in combination with the drawings.

[0035] Referring toFigures 1 to 5 As shown, according to the embodiments of the present application, a cleaning device is provided, which comprises a main machine 10, a suction mechanism 20, a cleaning member 30 and a dust collecting box (not shown in the drawings).

[0036] Specifically, the bottom of the main machine 10 is provided with a shell 11 having a receiving cavity 101 and a dust suction port 102 communicating with the receiving cavity 101; the suction mechanism 20 is arranged in the main machine 10 and has an inlet end 21 and an outlet end 22; the cleaning member 30 is rotatably arranged in the receiving cavity 101; the dust collecting box is arranged in the main machine 10 and respectively communicates with the inlet end 21 and the dust suction port 102; wherein at least one air outlet part 40 is arranged in the receiving cavity 101, the at least one air outlet part 40 is located at the outer circumferential side of the dust suction port 102 and is arranged offset from the dust suction port 102, and the receiving cavity 101 communicates with the outlet end 22 through the air outlet part 40. It can be understood that the air outlet part 40 in the present embodiment can be provided as one, two or more than two; the cleaning member 30 in the present embodiment comprises a rolling brush.

[0037] In the present embodiment, the air outlet part 40 is used to communicate with the outlet end 22 of the suction mechanism 20, and the air outlet part 40 is provided with air by the suction mechanism 20 to blow air into the receiving cavity 101; the dust suction port 102 opened on the shell 11 is used to communicate with the dust collecting box, and the dust suction port 102 is provided with suction force by the inlet end 21 of the suction mechanism 20 to suck the dust and garbage and other impurities in the receiving cavity 101 into the dust collecting box. During the working process of the cleaning device, with the rotation of the cleaning member 30, the cleaning member 30 can sweep the dust and garbage existing on the ground and other cleaning surfaces into the receiving cavity 101, and these dust and garbage will enter the dust collecting box from the dust suction port 102 under the action of the suction force of the suction mechanism 20. In this process, due to the adsorption of the dust and garbage, the dust and garbage will be adsorbed on the cavity wall of the receiving cavity 101 offset from the dust suction port 102, and cannot enter the dust collecting box from the dust suction port 102. Therefore, the present embodiment is provided with the air outlet part 40 in the receiving cavity 101, and the air outlet part 40 is located at the outer circumferential side of the dust suction port 102 and is arranged offset from the dust suction port 102, when the air from the outlet end 22 enters the receiving cavity 101 through the air outlet part 40, the airflow ejected from the air outlet part 40 will flow in the receiving cavity 101, thereby blowing off the dust and garbage attached to the cavity wall of the receiving cavity 101 offset from the dust suction port 102, at the same time, the airflow blown out from the outlet end 22 enters the receiving cavity 101 through the air outlet part 40, and can form a specific airflow field around the dust suction port 102, thereby promoting the blown-off dust and garbage to converge towards the dust suction port 102 and be sucked into the dust collecting box, avoiding the dust and garbage and other impurities being attached to the cavity wall of the receiving cavity 101 offset from the dust suction port 102 or randomly drifting in the receiving cavity 101 and cannot be sucked into the dust collecting box, effectively improving the dust removal efficiency of the cleaning device.

[0038] In other words, in this embodiment, by providing at least one air outlet 40 in the accommodating cavity 101, and by positioning the air outlet 40 on the outer periphery of the suction port 102 and offset from the suction port 102, when dust and debris are adsorbed on the cavity wall of the accommodating cavity 101 offset from the suction port 102, the airflow ejected from the air outlet 40 will flow within the accommodating cavity 101, thereby blowing off the dust and debris adhering to the cavity wall of the accommodating cavity 101 offset from the suction port 102. Furthermore, the air outlet 40 can gather the blown-off dust and debris towards the suction port 102, causing the dust and debris to be sucked into the dust collection box, effectively improving the dust removal efficiency of the cleaning device.

[0039] Furthermore, in this embodiment, the suction mechanism 20 that provides airflow to the air outlet 40 and the suction mechanism 20 that provides suction to the dust inlet 102 are connected by the same suction mechanism 20, without the need to add additional power components to provide airflow or suction, which effectively improves the space utilization of the cleaning device and reduces the manufacturing cost of the cleaning device.

[0040] Furthermore, in this embodiment, the air outlet 40 is disposed on at least one of the housing 11 and the cleaning component 30. That is to say, in this embodiment, the air outlet 40 may be disposed only on the housing 11, or only on the cleaning component 30, or simultaneously on both the housing 11 and the cleaning component 30.

[0041] Specifically, by providing an air outlet 40 on the housing 11 and / or the cleaning component 30, the airflow blown from the outlet end 22 can be effectively guided into the receiving cavity 101, thereby ensuring that the airflow in the receiving cavity 101 is more uniform, preventing dust and debris from accumulating on the cavity wall of the receiving cavity 101 away from the suction port 102, and effectively improving the dust removal efficiency of the cleaning device.

[0042] Further, see Figures 1 to 3 As shown, in this embodiment, the housing 11 is along the thickness direction of the host 10 (see attached diagram). Figure 3 The projection of the direction indicated by the letter X includes a long strip, with the suction port 102 located in the middle of the length of the strip, and the air outlet 40 is oriented towards the suction port 102.

[0043] Specifically, the dust suction port 102 in the embodiment is located at the middle position of the length direction of the long strip-shaped, so that the dust suction range of the dust suction port 102 can be relatively balanced, when the cleaning device starts to work, the dust and garbage and the like in the accommodation cavity 101 are more easily sucked away from the dust suction port 102, at the same time, since the air outlet direction of the air outlet part 40 in the embodiment is arranged towards the dust suction port 102, when the dust and garbage and the like impurities are adsorbed on the cavity wall of the accommodation cavity 101, the airflow sprayed from the air outlet part 40 flows along the cavity wall of the accommodation cavity 101, so as to blow off the dust and garbage and the like impurities attached to the cavity wall of the accommodation cavity 101, the blown-off dust and garbage and the like converge towards the dust suction port 102 along the air outlet direction of the air outlet part 40, further enhancing the dust suction effect of the cleaning device. In addition, the long strip-shaped shell 11 provides sufficient rotation space for the cleaning element 30, facilitating the rotation of the cleaning element 30.

[0044] Further, referring to Figure 1 and Figure 4 , the air outlet part 40 in the embodiment includes a first air outlet 41, the first air outlet 41 is arranged at the two opposite ends of the shell 11 along the length direction and communicates with the accommodation cavity 101; the main machine 10 is provided with a ventilation pipe 50 communicating with the outlet end 22, the ventilation pipe 50 includes two, and the two ventilation pipes 50 communicate with the two first air outlets 41 one by one.

[0045] Specifically, the air blown by the outlet end 22 of the suction mechanism 20 enters the accommodation cavity 101 through the first air outlet 41 corresponding to each ventilation pipe 50. Since the first air outlet 41 in the embodiment includes two, and the two first air outlets 41 are oppositely arranged, when the dust and garbage and the like impurities are adsorbed on the two side cavity walls of the accommodation cavity 101, the airflow blown by the outlet end 22 will be blown out from the two oppositely arranged first air outlets 41 from the two side cavity walls of the accommodation cavity 101 deviating from the dust suction port 102, under the blockage and disturbance of the air force, the dust and garbage and the like impurities are difficult to be adsorbed on the two side cavity walls of the accommodation cavity 101 deviating from the dust suction port 102, so as to effectively prevent the dust and garbage from accumulating in the accommodation cavity 101, and the blown-off dust and garbage will converge towards the dust suction port 102 along the air outlet direction of the first air outlet 41, and be sucked into the dust collecting box under the suction force of the suction mechanism 20, in this way, the dust removal effect of the two side cavity walls of the accommodation cavity 101 is improved, and the dust removal efficiency of the cleaning device is effectively improved.

[0046] Further, referring to Figure 2 and Figure 5As shown, the cleaning piece 30 in the embodiment includes a rotating shaft 31 rotatably arranged in the accommodating cavity 101, and the main machine 10 is provided with a ventilation pipe 50 in communication with the outlet end 22; the air outlet portion 40 includes a second air outlet 42 and an air inlet channel 43 in communication with the second air outlet 42, the second air outlet 42 is arranged on the outer surface of the rotating shaft 31 and located at the opposite ends of the rotating shaft 31 along the length direction, and the second air outlet 42 is in communication with the accommodating cavity 101, and the air inlet channel 43 is arranged in the rotating shaft 31 and extends along the axial direction of the rotating shaft 31, and the air inlet channel 43 is in communication with the ventilation pipe 50.

[0047] Specifically, the air blown out of the outlet end 22 of the suction mechanism 20 enters the air inlet channel 43 through the ventilation pipe 50, and then is blown into the accommodating cavity 101 from the second air outlet 42. During the rotation of the rotating shaft 31, the second air outlet 42 located at the two ends of the rotating shaft 31 will continuously blow air towards the accommodating cavity 101, and this airflow can blow off the dust and garbage and other impurities adsorbed on the two side cavity walls of the accommodating cavity 101 deviating from the dust suction port 102, so that the dust and garbage are more easily collected into the dust collecting box along the air outlet direction of the second air outlet 42 towards the dust suction port 102. At the same time, since the second air outlet 42 in the embodiment is arranged at the two ends of the rotating shaft 31 along the length direction and is in communication with the accommodating cavity 101, even if the dust and garbage and other impurities are close to the rotating shaft 31 during cleaning, they will also be blown away by the airflow blown out of the second air outlet 42, avoiding the accumulation of too much dust and garbage on the cleaning piece 30 to affect the mechanical properties of the cleaning piece 30, effectively ensuring the normal rotation of the cleaning piece 30.

[0048] Further, referring to Figure 5 As shown, the rotating shaft 31 in the embodiment is provided with a plurality of second air outlets 42 at each end, and the plurality of second air outlets 42 are arranged at intervals along the circumferential direction of the rotating shaft 31. It can be understood that in the embodiment, the second air outlets 42 at each end of the rotating shaft 31 can be two, or two or more, which is not specifically limited in the application.

[0049] Specifically, the plurality of second air outlets 42 in the embodiment are arranged at intervals along the axial direction of the rotating shaft 31, which can form a full-range airflow in the rotation direction of the rotating shaft 31, thereby facilitating blowing up the dust and garbage on the cavity wall of the accommodating cavity 101 from various angles, expanding the sweeping range of the air outlet portion 40 in the accommodating cavity 101, and further facilitating blowing the dust and garbage from the two side cavity walls of the accommodating cavity 101 deviating from the dust suction port 102 towards the dust suction port 102, and further improving the dust removal efficiency of the cleaning device.

[0050] Further, referring to Figure 2As shown, the shell 11 in the embodiment has a guide section 111, which is arranged at two opposite ends of the dust suction port 102 and is inclined towards the dust suction port 102. In this way, the dust and garbage in the accommodation cavity 101 blown up by the air outlet 40 can be effectively collected to the dust suction port 102 along the flow of the air current, thereby improving the dust removal efficiency of the cleaning device. At the same time, the guide section 111 in the embodiment is arranged at two opposite ends of the dust suction port 102, which expands the dust suction range of the dust suction port 102, and the dust and garbage at a position far away from the dust suction port 102 can be collected under the suction of the suction mechanism 20.

[0051] Further, referring to Figure 1 As shown, the host 10 in the embodiment is provided with a ventilation pipe 50, which includes a hose that is in communication with the air outlet 40 and the outlet end 22.

[0052] Specifically, since the host 10 internally contains various electronic elements, mechanical components, etc., the space is very compact and irregular in shape, and in order to adapt to the complex structure inside the host 10, the ventilation pipe 50 in the embodiment is arranged as a hose, which improves the flexibility of the layout of the ventilation pipe 50 in the host 10, so that the ventilation pipe 50 can easily bypass the obstacles inside the host 10 to adapt to different installation positions and angle requirements.

[0053] Further, referring to Figure 1 As shown, the host 10 in the embodiment is provided with an air outlet channel 60 and a ventilation pipe 50, the air outlet channel 60 is in communication with the outlet end 22 and extends to the outer edge of the host 10, and the air outlet channel 60 is in communication with the ventilation pipe 50 through a pipe joint 70.

[0054] Specifically, the combination of the air outlet channel 60, the pipe joint 70 and the ventilation pipe 50 in the embodiment forms a complete air circulation path. Since the air outlet channel 60 in the embodiment is in communication with the outlet end 22 and extends to the outer edge of the host 10, and the air outlet channel 60 is in communication with the ventilation pipe 50 through the pipe joint 70, when the air current generated by the suction mechanism 20 enters the air outlet channel 60 from the outlet end 22, most of the air current will blow to the outside of the host 10, and only a small part of the air current will enter the ventilation pipe 50 through the pipe joint 70, and then be blown into the accommodation cavity 101 through the air outlet 40, thereby facilitating the blowing of the dust and garbage and other impurities adhered to the cavity wall of the accommodation cavity 101 to the dust suction port 102.

[0055] On the other hand, the application also provides a cleaning system, which comprises the above-mentioned cleaning device, and therefore, the cleaning system comprises all the technical effects of the above-mentioned cleaning device.
