[0045] The terms "first", "second", "third" (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0047] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0048] The dust collector generally comprises a suction head and an operation main body connected with the suction head. The suction head can be dragged on the ground. A handle is arranged on the top of the operation main body. A user holds and pushes and pulls the operation main body through the handle, so as to drive the suction head to move. Dust collecting boxes and a fan and other components are arranged on the operation main body. The fan is used to generate negative pressure, so that the suction port on the suction head generates suction force, thereby realizing the dust collection function.
[0049] However, the coverage area of the suction port on the suction head of the current dust collector is limited. During the cleaning process, dust is prone to accumulate in some corners and edge positions. The suction port cannot cover the corners of the room and positions such as the feet of tables and chairs due to the shape and structure of the suction head of the dust collector, resulting in difficult cleaning of these edge positions and poor cleaning effect.
[0050] In order to solve the above technical problems, the embodiments of the present application provide a cleaning device and a cleaning equipment. The cleaning device is used for the cleaning equipment. A dust suction pipeline and a blowing pipeline are arranged on the cleaning device respectively to realize the functions of dust suction and dust lifting. The airflow of the dust lifting pipeline is blown out from the blowing port. The stubborn dust attached to the ground or the deep layer of the blanket can be blown up. The dust on the surface to be cleaned is lifted in the dust lifting cavity. The dust suction port can suck the lifted dust into the dust suction pipeline through the opening of the dust blocking plate. The dust blocking plate can prevent the lifted dust from overflowing the dust lifting cavity, thereby maintaining high and good cleaning effect.
[0051] In order to facilitate understanding, the application scenario of the cleaning equipment provided by the embodiments of the present application will be described first.
[0052] The cleaning equipment provided by the embodiments of the present application has the dust suction function, including but not limited to a dust collector, a floor washing machine, a suction and mopping all-in-one machine and the like. The cleaning equipment can be applied to household cleaning and can also be applied to ground cleaning in other indoor or outdoor scenarios. The specific product types to which the equipment main body is applied and the specific application scenarios of the cleaning equipment are not limited in the embodiments of the present application.
[0053] Figure 1 A structural schematic diagram of a cleaning device provided for an embodiment of the present application; Figure 2 A bottom schematic diagram of a cleaning device provided for an embodiment of the present application.
[0054] Referring to Figure 1 and Figure 2 The present application provides a cleaning device 200, which comprises a base 210, a dust suction pipe 220 and a blowing pipe 230, and the dust suction pipe 220 and the blowing pipe 230 are both arranged on the base 210. The base 210 is provided with a dust suction port 201 and a dust lifting cavity 206, and both the dust suction port 201 and the dust lifting cavity 206 are directed downward below the base 210. Among them, the dust suction pipe 220 is in communication with the dust suction port 201, the cavity wall of the dust lifting cavity 206 is provided with a blowing port 202, and the blowing pipe 230 is in communication with the blowing port 202.
[0055] It can be understood that the dust suction pipe 220 can form a negative pressure, so that the dust suction port 201 generates suction force, thereby sucking the dust and sundries on the surface to be cleaned into the dust suction pipe 220. The blowing pipe 230 can form a positive pressure, so that the blowing port 202 can blow air flow towards the surface to be cleaned, thereby lifting dust in the dust lifting cavity 206, so that the dust suction port 201 has higher dust suction efficiency.
[0056] In some embodiments, the bottom of the base 210 is provided with a dust blocking plate 240, the dust blocking plate 240 is located between the dust suction port 201 and the blowing port 202, the side of the dust blocking plate 240 facing the blowing port 202 forms part of the cavity wall of the dust lifting cavity 206, and the dust blocking plate 240 is provided with an opening 241, the opening 241 is in communication with the dust suction port 201 and the dust lifting cavity 206.
[0057] Among them, the dust blocking plate 240 separates the dust lifting cavity 206 from the dust suction port 201, so that the air flow blown out by the blowing port 202 can form an impact force to quickly lift the dust, and the opening 241 provided on the dust blocking plate 240 can form a channel for the air flow to pass through between the dust suction port 201 and the dust lifting cavity 206, and the negative pressure formed can suck the dust in the dust lifting cavity 206 into the dust suction pipe through the opening 241.
[0058] It should be noted that in the cleaning device 200 provided by the embodiments of the present application, the dust suction pipeline 220 and the air blowing pipeline 230 are respectively used to realize the functions of dust suction and dust raising. The airflow of the air blowing pipeline 230 is blown out from the air blowing port 202, which can blow up the stubborn dust attached to the ground or deep in the blanket, raise the dust on the surface to be cleaned in the dust raising cavity 206, and the air suction port 201 can suck the raised dust into the dust suction pipeline 220 from the opening 241 of the dust blocking plate 240, while the dust blocking plate 240 can prevent the raised dust from overflowing out of the dust raising cavity 206, thereby maintaining a high and good cleaning effect.
[0059] First, the structure of the air suction port 201 and the dust raising cavity 206 will be described in detail.
[0060] Please continue to refer to Figure 1 and Figure 2 In a possible implementation, the air suction port 201 extends along a first direction, and the dust raising cavity 206 extends in a direction parallel to the air suction port 201. The first direction is perpendicular to the cleaning direction of the cleaning device 200. The air blowing port 202 is located on the front side of the air suction port 201 along the cleaning direction of the cleaning device 200.
[0061] The first direction is defined as the X direction, and the cleaning direction of the cleaning device 200 is the Y direction.
[0062] It can be understood that the air suction port 201 can have a strip-shaped structure, and the air suction port 201 can extend along the width direction of the cleaning device 200, wherein the width direction of the cleaning device 200 is perpendicular to the moving direction of the cleaning device 200 during cleaning. During the cleaning process of the cleaning device 200, the dust raising cavity 206 can have a larger coverage area, and the corresponding air suction port 201 can efficiently suck the raised dust into the dust suction pipeline 220.
[0063] In some embodiments, the length of the air suction port 201 is greater than or equal to the length of the dust raising cavity 206, and the projection of the air suction port 201 in the cleaning direction of the cleaning device 200 covers the dust raising cavity 206, thereby avoiding dust overflow from both ends of the dust raising cavity 206.
[0064] For example, the air blowing port 202 can be located in front of the air suction port 201 along the cleaning direction of the cleaning device 200. During the cleaning process, the air suction port 201 can pass through the area of the dust raising of the air blowing port 202, ensuring that the raised dust is sucked into the dust suction pipeline.
[0065] Figure 3 The partitioned schematic diagram of the air blowing port in the cleaning device provided by the embodiments of the present application.
[0066] For example, please refer to Figure 3The blowing port 202 has a plurality of blowing areas 202a, which are respectively located at different positions around the suction port 201, so that the cleaning range of the cleaning device 200 can be expanded, and the corner positions of the scene to be cleaned can be more easily cleaned.
[0067] Please continue to refer to Figure 1 and Figure 2 As an optional embodiment, the dust suction pipe 220 and the blowing pipe 230 are arranged along the height direction of the base 210, and the blowing pipe 230 is located above the dust suction pipe 220. In this way, the longitudinal space of the cleaning device 200 can be fully utilized, and the structural compactness of the cleaning device 200 can be improved.
[0068] For example, the base 210 has a suction cavity 203 and a blowing cavity 204, the dust suction pipe 220 communicates with the suction cavity 203, and the blowing pipe 230 communicates with the blowing cavity 204. Among them, the suction cavity 203 and the blowing cavity 204 are arranged in layers along the height direction of the base 210, and the suction cavity 203 forms the suction port 201 towards one end below the base 210.
[0069] It should be noted that the blowing cavity 204 can extend from above the suction cavity 203 to the front end of the suction cavity 203 along the cleaning direction of the cleaning device 200, and communicate with the dust lifting cavity 206 through the blowing port 202. During the cleaning process, the suction port 201 can pass through the area where the dust is lifted by the blowing port 202, so that the lifted dust can be sucked into the dust suction duct.
[0070] Figure 4 The orientation of the blowing port in the cleaning device provided by the embodiment of the present application is shown Figure 1 ; Figure 5 The orientation of the blowing port in the cleaning device provided by the embodiment of the present application is shown Figure 2 .
[0071] Please refer to Figure 4 and Figure 5 , and combine Figure 1 and Figure 2 In some embodiments, the blowing port 202 can be a plurality of blowing ports 202, which are arranged at intervals along the length direction of the dust lifting cavity 206, and the blowing direction of at least one of the plurality of blowing ports 202 is inclined relative to the vertical direction towards the suction port 201, so that the dust gas in the dust lifting cavity 206 can quickly pass through the opening 241 to the suction port 201 through the dust blocking plate 240.
[0072] For example, the inclination angle of the blowing direction of the blowing port 202 relative to the vertical direction can include but is not limited to 1°, 10°, 20°, 30°, 45°, 60°, etc., and the present application does not make specific limitation on this.
[0073] For example, the air outlet 202 can be a perforated structure, so that the airflow blown out by the air outlet 202 has a higher flow rate, so that the airflow impacts the surface to be cleaned downwards, which can remove stubborn dust and debris.
[0074] In some embodiments, the wall of the dust-generating chamber 206 is arc-shaped, and the air inlet 201 is located at the top of the dust-generating chamber 206, thereby improving the smoothness of airflow, reducing wind resistance, and preventing dust in the dusty air from falling.
[0075] For example, there can be multiple openings 241, which are spaced apart along the length of the dust baffle 240. The multiple openings 241 form multiple dust guide channels 205 between the air intake 201 and the dust chamber 206, thereby improving the efficiency of the air intake 201 in drawing dust into the dust chamber 206.
[0076] As an optional implementation, the first end of the dust baffle 240 is rotatably connected to the base 210, and the second end of the dust baffle 240 faces downward toward the base 210. The cleaning device 200 is configured to adjust the relative size of the suction port 201 and the dust-collecting chamber 206 by rotating the dust baffle 240. When the dust baffle 240 deflects toward the dust-collecting chamber 206, the area of the suction port 201 can be increased while the area of the dust-collecting chamber 206 can be decreased; conversely, when the dust baffle 240 deflects toward the suction port 201, the area of the suction port 201 can be decreased while the area of the dust-collecting chamber 206 can be increased.
[0077] Understandably, the rotation of the dust baffle 240 guides the flow of dust and air, allowing it to flow more quickly and smoothly into the suction port 201. Furthermore, the deflection direction and angle of the dust baffle 240 can be adjusted according to specific application scenarios. For example, when cleaning flat areas and non-corner areas, or when there is relatively more dust on the ground, the dust baffle 240 can be deflected towards the dust-raising chamber 206, reducing the volume of the dust-raising chamber 206 and increasing the area of the suction port 201, thereby improving the suction efficiency of the suction port 201 while preventing excessive dust from being stirred up and causing dust and air to overflow.

[0080] For example, the air outlet side of the first fan unit 122 is communicated with a blowing pipeline 230. The single fan unit is used to realize the functions of negative pressure dust suction and positive pressure dust blowing.
[0081] For example, the fan assembly 120 further comprises a second fan unit (not shown), the air outlet side of the second fan unit is communicated with the blowing pipeline 230. The air outlet side of the first fan unit 122 is communicated with an external space, and the two fan units are used to realize the functions of negative pressure dust suction and positive pressure dust blowing respectively.
[0082] The device main body 100 is used as a main structure of the cleaning device and is used for driving the cleaning device 200 to move on a surface to be cleaned by a user, and the cleaning device 200 can suck dust and sundries on the surface to be cleaned.

[0085] It can be understood that the dust collecting cavity 111a and the exhaust cavity 111b are two spaces which are independent of each other, the cavity passage for the air inlet and outlet of the fan assembly 120 can be formed by using the structure of the dust collecting shell 112, so that the volume and weight of the device main body 100 are reduced.
[0086] For example, the dust collecting cavity 111a and the exhaust cavity 111b can be arranged side by side, and the smoothness of the air flow circulation of the dust collecting cavity 111a and the exhaust cavity 111b.
[0087] The device body 100 can further include a filter 1145 arranged in the dust collection shell 112, the filter 1145 being located between the dust collection cavity 111a and the air inlet side of the fan assembly 120, so as to filter the air flow sucked into the dust collection cavity 111a, avoid dust pollution and damage to the fan assembly 120, and avoid mixing of dust when the air flow is blown to the air outlet 202 under the positive pressure of the fan.
[0088] In another possible implementation, the cleaning device can further include an air exhaust pipe 140. The device body 100 includes a dust collection shell 112, the fan assembly 120 being connected to the dust collection shell 112, the dust collection shell 112 being arranged to form a dust collection cavity 111a, the dust collection cavity 111a being in communication with the dust suction air duct, and the air inlet side of the fan assembly 120 being in communication with the dust collection cavity 111a. The air exhaust pipe 140 is located at the side of the dust collection shell 112, the first end of the air exhaust pipe 140 being in communication with the air outlet side of the fan assembly 120, and the second end of the air exhaust pipe 140 being in communication with the air blowing air duct.
[0089] It can be understood that the separately arranged air exhaust pipe 140 can make the air flow blown by the fan assembly 120 more smoothly, and reduce wind noise and wind resistance.
[0090] Exemplarily, the air exhaust pipe 140 can be a flexible pipe, for example, a corrugated pipe, a rubber pipe, etc., which is not limited in the embodiment of the application.
[0091] In some embodiments, the device body 100 further includes an air inlet pipe 113 and a flow guide assembly 114, the air inlet pipe 113 being connected to the dust collection shell 112, the air inlet pipe 113 being at least partially arranged in the dust collection shell 112, and the outer wall of the air inlet pipe 113 and the inner wall of the dust collection shell 112 being arranged to form the dust collection cavity 111a. The dust collection cavity 111a is used to store separated dust and sundries.
[0092] The air inlet pipe 113 is provided with an air inlet 1131 and a cyclone outlet 1132, the air inlet 1131 being directed to the outside of the dust collection shell 112, and the cyclone outlet 1132 being directed to the inside of the dust collection shell 112. The flow guide assembly 114 is arranged in the dust collection shell 112, the dust collection shell 112 being provided with an air outlet 1121 on the side away from the air inlet pipe 113, the flow guide assembly 114 being opposite to the cyclone outlet 1132 and at least partially arranged in the air inlet pipe 113, so as to form a cyclone flow channel between the flow guide assembly 114 and the inner wall of the air inlet pipe 113.
[0093] It can be understood that the external dust gas can enter the air inlet pipe 113 from the air inlet 1131, and when flowing out from the cyclone outlet 1132, the dust gas can form a cyclone through the cyclone passage between the air inlet pipe 113 and the flow guide assembly 114, and the flow guide assembly 114 can guide the flow of the dust gas, so that the dust and impurities can be separated by rotation and centrifugal motion.
[0094] It should be noted that in the cleaning device provided by the embodiments of the present application, the inner wall of the dust collecting shell 112 forms a dust collecting cavity 111a outside the air inlet pipe 113, the space in the dust collecting shell 112 is fully utilized, and the flow guide assembly 114 is arranged at the top cyclone outlet 1132 of the air inlet pipe 113, and the dust gas is separated at the end of the air inlet pipe 113, which has good dust gas separation effect, reduces the volume of the entire device main body 100, forms a long barrel structure, and thus when applied to the cleaning device, the overall weight of the cleaning device can be reduced, the overall center of gravity can be reduced, the weight can be avoided to be concentrated at the holding end of the cleaning device, and the user experience is improved.
[0095] In some embodiments, the flow guide assembly 114 can include a flow guide vane 1141 arranged in the cyclone outlet 1132, and the flow guide vane 1141 is configured to guide the airflow passing through the cyclone outlet 1132 to form a cyclone, so that the airflow mixed with dust and impurities can be rotated out of the cyclone outlet 1132, and the dust and impurities can be separated from the airflow by centrifugal force, thereby improving the dust gas separation efficiency.
[0096] For example, the flow guide assembly 114 can include a plurality of flow guide vanes 1141 arranged at intervals around the central axis of the air inlet pipe 113, and the plurality of flow guide vanes 1141 can form a plurality of flow channels, thereby improving the efficiency and flow rate of the airflow in the air inlet pipe 113 to form a cyclone, and further increasing the centrifugal force of the dust and impurities when being thrown out during dust gas separation, thereby having better dust gas separation effect and efficiency.
[0097] For example, the number of flow guide vanes 1141 can be two, three, four or more, and the embodiments of the present application do not make specific limitations thereto.
[0098] For example, the flow guide vane 1141 can be welded to the inner wall of the cyclone outlet 1132. The surface of the flow guide vane 1141 can be arc-shaped to ensure the smoothness of the airflow when forming a cyclone, and to reduce wind resistance and wind noise.
[0099] In some embodiments, the flow guide assembly 114 can include a flow guide 1142 and a filter 1145, the flow guide 1142 is arranged opposite to the cyclone outlet 1132, the dust collecting shell 112 is provided with an air outlet 1121 at an end away from the air inlet pipe 113, and a fan assembly 120 is connected to the air outlet 1121, and the filter 1145 is arranged between the flow guide 1142 and the fan assembly 120.
[0100] It can be understood that the cyclone airflow flowing out of the cyclone outlet 1132 can be thrown out to the inner wall of the dust collecting shell 112 through the flow guide 1142, so as to have a better dust-gas separation effect, and the fine dust remaining in the airflow can be filtered by the filter 1145, so as to ensure the cleanliness of the airflow entering the fan assembly 120 and the exhaust airflow.
[0101] In some embodiments, the flow guide 1142 can include a flow guide bracket 1143 and a flow guide ball 1144, the flow guide bracket 1143 is connected to the inner wall of the dust collecting shell 112, the flow guide ball 1144 is connected to the flow guide bracket 1143, and at least part of the structure of the flow guide ball 1144 is inserted into the cyclone outlet 1132, so that the airflow flowing out of the cyclone outlet 1132 can be accelerated to rotate and diffuse to the inner wall of the dust collecting shell 112 under the guidance, thereby improving the dust-gas separation efficiency.
[0102] It can be understood that the flow guide bracket 1143 plays a role in fixing the flow guide ball 1144 on one hand, and on the other hand, when the dust-gas is discharged from the cyclone outlet 1132, the airflow will continue to flow upward and diffuse to the four directions under the guidance of the flow guide ball 1144, and the flow guide bracket 1143 can block the airflow and make the dust and sundries separated and treated under the centrifugal force to sink downward.
[0103] For example, the flow guide ball 1144 is coaxially arranged with the air inlet pipe 113, so as to ensure the smoothness of the airflow flowing out of the cyclone outlet 1132, and avoid the cyclone outlet 1132 generating turbulence.
[0104] In some embodiments, the inner wall of the cyclone outlet 1132 is arranged to form an air outlet area, the radial cross-sectional diameter of the air outlet area gradually increases in the direction towards the outside of the cyclone outlet 1132, and the end of the flow guide ball 1144 is inserted into the air outlet area.
[0105] It can be understood that the cyclone outlet 1132 can form a horn-shaped structure for increasing the flow passage cross-sectional area of the cyclone outlet 1132, which is conducive to the diffusion of the airflow out of the cyclone outlet 1132, so as to more efficiently separate the dust and gas. Since the flow guide ball 1144 is inserted into the air outlet area, the flow guide ball 1144 will compress the ventilation area of the cyclone outlet 1132, so that the airflow can increase the flow rate while diffusing to the four directions, thereby increasing the centrifugal force of the dust and sundries during the cyclone dust-gas separation.
[0106] Exemplarily, the cross-sectional dimension of the guide ball 1144 in the radial direction of the dust collecting shell 112 first increases and then decreases from the guide support 1143 to the inside of the cyclone outlet 1132. The cross-sectional dimension of the part of the guide ball 1144 inserted into the cyclone outlet 1132 gradually decreases, the air outlet area of the cyclone outlet 1132 can be controlled through the guide ball 1144, and then the air speed and air pressure of the airflow are controlled, so that the airflow can continue to rotate after being discharged from the cyclone outlet 1132, and the dust-gas separation effect is maintained.
[0107] In some embodiments, a ventilation hole is arranged on the cyclone support, and the ventilation hole communicates the dust collecting cavity 111a and the air outlet 1121. The ventilation hole is arranged close to the connection position of the guide ball 1144 and the cyclone support. The ventilation hole is used for the airflow after dust-gas separation to flow out, and the ventilation hole is arranged close to the root of the guide ball 1144, so that the ventilation hole is close to the center position of the guide support 1143 as much as possible, and the airflow with dust directly entering into the ventilation hole when being discharged from the cyclone outlet 1132 can be prevented.
[0108] It should be noted that the cyclone support can be connected with the inner wall of the dust collecting shell 112 by welding, or the cyclone support can be fixed relative to the inner wall of the dust collecting shell 112 by clamping and limiting.
[0109] Exemplarily, the filter 1145 can include a high efficiency particulate air filter (HEPA filter), and the filter 1145 can filter dust impurities of micron level, so as to ensure the cleanliness of the air discharged by the equipment body 100.
[0110] It should be noted that the air inlet pipe 113 and the filter 1145 can be connected with the dust collecting shell 112 in a detachable manner, including but not limited to threaded connection, buckle connection, elastic interference fit, etc., and the embodiments of the present application do not make specific limitation thereto.
[0111] In some embodiments, the outer wall of the air inlet pipe 113 is provided with a turbulence portion 1133 extending towards the inner wall of the dust collecting shell 112.
[0112] It can be understood that when the airflow enters the dust collecting cavity 111a to rotate to throw out the dust impurities, the turbulence portion 1133 can block the airflow and the dust impurities, so as to accelerate the falling of the dust and impurities, and prevent the settled dust from being carried up by the airflow.
[0113] Exemplarily, the turbulence portion 1133 can be arranged at the top of the air inlet pipe 113 or at the middle position. The turbulence portion 1133 can be welded with the outer wall of the air inlet pipe 113.
[0114] In some embodiments, the turbulence portion 1133 can be multiple, and the multiple turbulence portions 1133 are spaced apart around the circumference of the air inlet pipe 113. The turbulence portion 1133 is in abutment with the inner wall of the dust collection shell 112 away from the end of the air inlet pipe 113, so that it can have a better turbulence effect and further accelerate the falling of dust and debris into the dust collection cavity 111a.
[0115] It should be noted that when the air inlet pipe 113 is assembled with the dust collection shell 112, the air inlet pipe 113 is inserted into the inside of the dust collection shell 112, the lower end of the connecting portion is screwed with the dust collection shell 112, and the upper end of the turbulence portion 1133 is in abutment with the inner wall of the dust collection shell 112, so as to maintain the stability of the air inlet pipe 113 in the dust collection shell 112 and avoid the radial displacement or shaking of the air inlet pipe 113.
[0116] In some embodiments, the dust collection shell 112 is provided with a dust collection bin cover 115, and the sidewall of the dust collection shell 112 is provided with a dust discharge port that communicates the dust collection cavity 111a with the outside of the dust collection shell 112. The dust collection bin cover 115 is connected with the dust collection shell 112, and the dust collection bin cover 115 is movably arranged relative to the dust discharge port to open or close the dust discharge port.
[0117] It can be understood that when the cleaning device is normally used, the dust collection bin cover 115 closes the discharge port to avoid dust leakage. When the dust collection cavity 111a needs to be cleaned, the dust collection bin cover 115 can be opened to pour out the dust and debris in the dust collection cavity 111a from the discharge port.
[0118] It should be noted that in the device main body 100 provided by the embodiments of the present application, the dust collection cavity 111a is formed by the space between the inside of the dust collection shell 112 and the air inlet pipe 113, so that when the dust and debris in the dust collection cavity 111a need to be cleaned, only the dust discharge port on the outer wall of the shell needs to be opened, without the need to remove the dust collection shell 112 from the cleaning device, thereby improving the convenience of cleaning the dust collection cavity 111a.
[0119] In some embodiments, the device main body 100 further comprises a battery assembly 130. The dust collection shell 112 is provided with an air inlet port 1131 and an air outlet port 1121 at the two axial ends thereof, the fan assembly 120 is detachably connected to one end of the dust collection shell 112 provided with the air outlet port 1121, and the fan assembly 120 communicates with the air outlet port 1121. The battery assembly 130 is detachably connected to the end of the fan assembly 120 away from the dust collection shell 112.
[0120] The dust collecting shell 112 can provide a passage for dust gas flow and separate the dust gas, and store the dust and sundries in the dust collecting cavity 111a. The fan assembly 120 is used to generate airflow, so that the air inlet 1131 of the device body 100 can form a negative pressure, thereby realizing the dust collection function. The battery assembly 130 is used to provide power for the fan assembly 120, so that the device body 100 applied to the cleaning device can be used with or without being plugged in.
[0121] In some embodiments, the dust collecting shell 112, the fan assembly 120, and the battery assembly 130 are coaxially arranged. In this way, along the axis of the device body 100, the dust collecting shell 112, the fan assembly 120, and the battery assembly 130 can be arranged in sequence and respectively form a part of the structure, so that the whole device body 100 forms an elongated rod-shaped structure.
[0122] It can be understood that the dust collecting shell 112 provides a passage for dust gas flow while forming a separation and storage space for dust and sundries with the air inlet pipe 113. The fan assembly 120 is located at the middle position of the device body 100. Compared with the prior art in which the fan is arranged at the top end, the weight of the device body 100 at the end is smaller in the embodiment of the present application, and the top of the device body 100 forms a rod-shaped structure with the battery assembly 130, which is convenient for the user to hold during use and more labor-saving in operation.
[0123] It should be noted that the device body 100 provided by the present application applied to the cleaning device can play the role of an operation body, and the coaxially assembled dust collecting shell 112, fan assembly 120, and battery assembly 130 form a rod-shaped structure for the user to hold during use. Since the three components are arranged in sequence, the axial weight distribution of the overall structure of the device body 100 is more uniform, the structure is more compact and small, the lightweight effect of the device body 100 is realized, the weight of the hand holding position during use is reduced, and the use experience is improved.
[0124] In the embodiment of the present application, the fan assembly 120 arranged on the device body 100 has a positive pressure side and a negative pressure side. The negative pressure side air inlet is communicated with the dust collection air duct, and the positive pressure side air outlet is communicated with the blowing air duct. When the fan assembly 120 is started, the air inlet 201 forms a negative pressure to suck in the dust and sundries on the surface to be cleaned, and the air outlet 202 forms a positive pressure to blow out the airflow to the surface to be cleaned, so as to lift the stubborn dust and sundries attached to the corner position and the ground.
[0125] It can be understood that the cleaning device can have multiple working modes, including but not limited to a normal suction mode, a dust raising mode, etc., wherein when the normal suction mode is started, dust can be sucked in only from the air suction port 201, and the air blowing port 202 does not blow air flow; and when the dust raising mode is started, the air suction port 201 sucks in dust under the generation of negative pressure, and the air blowing port 202 blows air flow at the same time to raise dust and improve the cleaning efficiency on the surface to be cleaned.
[0126] The user can switch and select different working modes according to specific use scenarios, for example, the normal suction mode can be used when cleaning a relatively small amount of dust on the ground, and the dust raising mode can be used when cleaning indoor corners, seat placement areas, etc. The structure of the fan assembly 120 for realizing the above-mentioned function mode switching is described in detail below.
[0127] In some embodiments, the fan assembly 120 can include a fan housing 121 and a fan unit, the fan unit is arranged inside the fan housing 121, the fan housing 121 has a first air outlet 1211 and a second air outlet 1212, the first air outlet 1211 is in communication with the air blowing duct, and the second air outlet 1212 is in communication with the space outside the fan housing 121.
[0128] The cleaning device can further include a switching unit 123 arranged on the air outlet side of the fan unit in the fan housing 121; the switching unit 123 is configured to make the air outlet side of the fan unit communicate with any one of the first air outlet 1211 and the second air outlet 1212.
[0129] It can be understood that when the normal suction mode is started, the switching unit 123 can be switched to make the air outlet side of the fan unit communicate with the second air outlet 1212, so that the dust gas sucked in by the negative pressure of the fan unit from the air suction port 201 can be discharged into the external atmosphere after being filtered. When the dust raising mode is started, the switching unit 123 can be switched to make the air outlet side of the fan unit communicate with the first air outlet 1211, so that the dust gas sucked in by the negative pressure of the fan unit from the air suction port 201 can be blown to the surface to be cleaned from the air blowing port 202 through the air blowing duct to realize the dust raising function after being filtered.
[0130] For example, the switching unit 123 can include a motor and a movable plate, the motor can drive the movable plate to rotate to change the flow direction of the air flow on the air outlet side of the fan unit, and realize the air outlet side of the fan unit to communicate with the first air outlet 1211 and the second air outlet 1212 alternatively.
