[0060] 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.

[0061] Moreover, the terms "comprising" and "including" and any variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, system, product or apparatus that comprises a list of steps or elements not merely consists of those specifically identified herein, but can include additional steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0062] 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 only 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 work fall within the scope of protection of the present application.

[0063] 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. A dust collecting box is generally arranged on the operation main body. The dust and sundries sucked from the suction head can be filtered and collected in the dust collecting box.

[0064] However, at present, the dust collector only collects dust and sundries through single filtering during the cleaning process. The space for storing the dust and sundries is small. The dust collecting box is easily filled up. The dust collecting box needs to be cleaned frequently. When the dust collecting box is cleaned, the fine dust is easily inhaled by the human body, affecting the health of the human body. In addition, since the single filtering needs to collect large-volume sundries and filter fine dust, the filtering structure for single filtering is easily blocked, and the filtering effect is poor. The dust may be discharged again, causing secondary pollution.

[0065] In order to solve the above technical problems, the embodiments of the present application provide a cleaning equipment. Spaces for storing dust and sundries and corresponding filtering and separating structures are arranged on the suction disc and the dust collecting device respectively. The dust and sundries sucked from the suction disc can be collected and filtered through the structure on the suction disc first. Part of the large-volume sundries is left in the storage space of the suction disc. The other dust and sundries can be dust-air separated through the dust collecting device. The remaining dust and sundries are collected and stored. In this way, the filtering efficiency of the cleaning equipment on the dust and sundries is improved, secondary pollution is avoided, the dust and sundries can be stored in two independent spaces, the space for storing the dust and sundries is larger, the user needs to clean less frequently, the fine dust is prevented from being inhaled into the human body, and the user experience is improved.

[0066] In order to facilitate understanding, the application scenario of the cleaning equipment provided by the embodiments of the present application is described first.

[0067] The cleaning equipment provided in the embodiments of the present application has a dust suction function, including but not limited to a vacuum cleaner, a floor washing machine, a vacuum and mop integrated machine, etc. The cleaning equipment can be applied to household cleaning, and can also be applied to ground cleaning in other indoor or outdoor scenes. The embodiments of the present application do not limit the specific product types to which the dust suction device is applied, and the specific application scenarios of the cleaning equipment.

[0068] Figure 1 A structural schematic diagram of the cleaning equipment provided in the embodiments of the present application is shown in the figure. Figure 2 An exploded view of the cleaning equipment provided in the embodiments of the present application is shown in the figure. Figure 3 A structural schematic diagram of the collecting box in the cleaning equipment provided in the embodiments of the present application is shown in the figure. Figure 4 A sectional view of the collecting box in the cleaning equipment provided in the embodiments of the present application is shown in the figure. Figure 5 An exploded view of the collecting box in the cleaning equipment provided in the embodiments of the present application is shown in the figure. Figure 6 An internal view of the collecting box in the cleaning equipment provided in the embodiments of the present application is shown in the figure.

[0069] Referring to Figures 1 to 6 The present application provides a cleaning equipment, which includes a dust suction device 100 and a suction disc 200. The suction disc 200 is movably connected with the dust suction device 100. The suction disc 200 is provided with a suction port 201 and a collecting cavity 202. The suction port 201 is in communication with the collecting cavity 202. The collecting cavity 202 is provided with a filter 210. Dust gas sucked from the suction port 201 can enter the collecting cavity 202 and flow out after being filtered by the filter 210. The collecting cavity 202 can store the filtered dust and sundries.

[0070] In the embodiments of the present application, the dust suction device 100 includes a dust collecting assembly 110 and a fan assembly 120 connected with each other. The dust collecting assembly 110 has a dust collecting cavity 111. The air inlet side of the fan assembly 120 is in communication with the dust collecting cavity 111. The dust collecting cavity 111 is in communication with the collecting cavity 202. The dust collecting cavity 111 is provided with a dust gas separation structure 114. Dust gas flowing out of the collecting cavity 202 can enter the dust collecting cavity 111 and be separated. The dust and sundries after the separation sink and are collected in the dust collecting cavity 111. The separated air is discharged from the dust suction device 100.

[0071] It can be understood that the suction disc 200 and the dust suction device 100 are respectively provided with spaces for filtering and separating dust and sundries and collecting the dust and sundries, forming a two-stage filtering structure. The two-stage filtering can distinguish dust and sundries of different volumes and store them in different spaces.

[0072] It should be noted that in the cleaning device provided in the present application, the dust and sundries sucked in from the air suction port 201 can be filtered through the collection cavity 202 first, and part of the sundries with large volume can be left in the collection cavity 202, and then the dust and sundries can be collected and stored through the dust collection cavity 111, so that the filtering efficiency of the cleaning device on the dust and sundries is improved, secondary pollution is avoided, the dust and sundries can be stored in two independent spaces, the space for storing the dust and sundries is larger, the user can avoid frequent cleaning, the fine dust is prevented from being sucked into the human body, and the user experience is improved.

[0073] The specific structures of the collection cavity 202 and the dust collection cavity 111 will be described in detail respectively as follows.

[0074] Please continue to refer to Figures 1 to 6 In a possible implementation, the collection cavity 202 has a suction port 2021 and a discharge port 2022, the suction port 2021 and the discharge port 2022 are located at opposite sides of the collection cavity 202 respectively, the suction port 2021 is in communication with the air suction port 201, and the discharge port 2022 is in communication with the dust collection cavity 111. The dust gas sucked in from the air suction port 201 can enter the collection cavity 202 from the suction port 2021, and then flow out of the collection cavity 202 from the discharge port 2022 and flow to the dust collection cavity 111.

[0075] It can be understood that a channel for the dust and sundries to settle down can be formed between the suction port 2021 and the discharge port 2022, and part of the sundries and particles can be left in the collection cavity 202 when the airflow sucked in from the suction port 2021 enters the collection cavity 202, so that the collection efficiency is improved.

[0076] In some embodiments, the filter 210 can divide the collection cavity 202 into a first cavity 202a and a second cavity 202b, the suction port 2021 is in communication with the first cavity 202a, and the discharge port 2022 is in communication with the second cavity 202b, and the volume of the first cavity 202a is greater than that of the second cavity 202b. When the airflow flows from the suction port 2021 to the discharge port 2022, the filter 210 can be used for filtering, so that the sundries and particles with large volume are collected in the collection cavity 202.

[0077] It can be understood that the airflow with dust and sundries first passes through the first cavity 202a, and the sundries with large volume filtered by the filter 210 are left in the first cavity 202a. The second cavity 202b provides a space and a channel for the dust gas to converge to the discharge port 2022.

[0078] Exemplarily, the filter 210 can be a plate structure. The filter 210 can be vertically arranged in the collecting cavity 202. An edge of the filter 210 can be welded with an inner wall of the collecting cavity 202, or be slidingly inserted through a sliding groove structure, or be fixedly connected through buckling, which is not specifically limited in the embodiments of the present application.

[0079] In some embodiments, the filter 210 is provided with a plurality of mesh holes 211 arranged in an array on the filter 210. The mesh holes 211 have a pore size of 0.2 mm to 1 mm. Dust and small-volume impurities with a diameter smaller than the mesh holes 211 can enter the dust collecting cavity 111 through the filter 210 along with the airflow, while impurities with a size larger than the mesh holes 211 are collected and stored in the collecting cavity 202.

[0080] It can be understood that the filter 210 can classify the dust and impurities to be collected and stored, so as to avoid large-volume impurities from entering the dust collecting cavity 111, and to avoid the collecting cavity 202 from being quickly filled up by too much dust and impurities.

[0081] Exemplarily, the pore size of the mesh holes 211 can include but is not limited to 0.2 mm, 0.3 mm, 0.5 mm, 0.9 mm, 1 mm, etc., which is not specifically limited in the embodiments of the present application.

[0082] Exemplarily, the filter 210 can include a plurality of filter baffles arranged in an array along the airflow direction to achieve a filtering effect on dust particles.

[0083] Exemplarily, the filter 210 can be a convolute baffle to form a convolute airflow channel, so as to achieve dust-air separation by utilizing centrifugal force when the airflow rotates.

[0084] Exemplarily, the filter 210 can be a filter sponge to adsorb dust and particles while allowing air to pass through.

[0085] In some embodiments, the suction port 2021 can be provided with a flexible baffle 220 arranged on a side of the suction port 2021 facing the inside of the collecting cavity 202, so as to ensure one-way flow of the airflow through the suction port 2021 and avoid dust and impurities in the collecting cavity 202 from leaking out of the suction port 2021.

[0086] It can be understood that when dust-air of the suction port 201 is sucked into the collecting cavity 202 under the action of negative pressure, the flexible baffle 220 is elastically deformed and opens the suction port 2021 under the pressure difference between the inside and outside of the collecting cavity 202, so that the dust-air enters the collecting cavity 202, and when the device is not started, the flexible baffle 220 returns to the initial state and blocks the suction port 2021.

[0087] Exemplarily, the flexible baffle 220 can be made of elastic materials such as rubber or silicone, and the embodiments of the present application do not make specific limitations in this regard.

[0088] In some embodiments, the suction cup 200 can include a base 230 and a collection box 240, the collection box 240 being detachably connected to the base 230, the suction port 201 being arranged at the bottom of the base 230, and the collection box 240 being configured to form a collection cavity 202 to facilitate cleaning of dust and sundries in the collection cavity 202.

[0089] It can be understood that the collection box 240 can be mounted above the base 230. The collection box 240 can be connected to the base 230 in the form of a buckle, and the base 230 is provided with a limiting rib or a limiting groove to ensure the accuracy of the installation position of the collection box 240, thereby avoiding misalignment of the suction port 2021 and the discharge port 2022 when they are docked on the base 230.

[0090] Exemplarily, the collection box 240 includes a box body 241 and a box cover 242, the box body 241 and the box cover 242 being rotatably opened and closed and being capable of being fixed by a buckle, and a sealing ring 243 being arranged between the box body 241 and the box cover 242. The box cover 242 is provided with a blocking rib, and the top end of the filter element 210 is abutted against or adjacently arranged with the blocking rib when the box cover 242 is closed relative to the box body 241, so as to separate the collection cavity 202.

[0091] Exemplarily, the front end of the collection box 240 along the cleaning direction of the suction cup 200 is communicated with the suction port 201, and the rear end of the collection box 240 along the cleaning direction of the suction cup 200 is communicated with the dust collection cavity 111, so as to reduce the turning of the airflow during the dust collection process, improve the smoothness of the airflow circulation, and thus improve the dust collection efficiency.

[0092] The structure of the dust collection assembly 110 will be described in detail below.

[0093] Figure 7 A structural schematic diagram of the dust collection assembly provided by the embodiments of the present application is shown in Figure 8 An exploded view of the dust collection assembly provided by the embodiments of the present application is shown in Figure 9 A sectional view of the air inlet pipe in the dust collection assembly provided by the embodiments of the present application is shown in

[0095] It can be understood that the dust collecting shell 112 is sleeved with the air inlet pipe 113, the space between the dust collecting shell 112 and the air inlet pipe 113 can be used to form the dust collecting cavity 111, the space utilization of the dust collecting assembly 110 is improved, and the miniaturization and light weight design of the dust collecting device are realized.

[0096] In some embodiments, the air inlet pipe 113 is provided with an air inlet 1131 and a cyclone outlet 1132 at the two axial ends respectively, the air inlet 1131 is communicated with the collecting cavity 202, and the end provided with the cyclone outlet 1132 is inserted into the inside of the dust collecting shell 112. The dust-gas separation structure 114 is arranged at the cyclone outlet 1132.

[0097] It can be understood that the dust-gas flowing out of the collecting cavity 202 can enter the air inlet pipe 113 from the air inlet 1131, circulate along the air inlet pipe 113, and flow out from the cyclone outlet 1132, the airflow flowing out forms a cyclone, and the dust-gas separation can be performed, so that the dust and sundries are settled in the dust collecting cavity 111.

[0098] In some embodiments, the dust-gas separation structure 114 can include a guide vane 1141, the guide vane 1141 is arranged in the cyclone outlet 1132, and the 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 sundries can rotate and discharge from the cyclone outlet 1132, thereby separating the dust and sundries from the airflow by using centrifugal force, and improving the efficiency of dust-gas separation.

[0099] Figure 10 The structure one of the air inlet pipe in the dust collecting assembly provided by the embodiments of the present application; Figure 11 The structure two of the air inlet pipe in the dust collecting assembly provided by the embodiments of the present application; Figure 12 The structure three of the air inlet pipe in the dust collecting assembly provided by the embodiments of the present application.

[0100] For example, Figures 7 to 12 The dust-gas separation structure 114 can include a plurality of guide vanes 1141, the plurality of guide vanes 1141 are arranged at intervals around the central axis of the air inlet pipe 113, the plurality of guide vanes 1141 can form a plurality of flow channels, the efficiency and flow rate of the airflow flowing out of the air inlet pipe 113 to form a cyclone are improved, and the centrifugal force of the dust and sundries thrown out during dust-gas separation is increased, so that the dust-gas separation has better effect and efficiency.

[0101] For example, the number of the guide vanes 1141 can be two, three, four or more, and the embodiments of the present application do not make specific limitation thereon.

[0102] For example, the guide vanes 1141 can be welded with the inner wall of the cyclone outlet 1132. The surface of the guide vanes 1141 can be arc-shaped to ensure the smoothness of the airflow forming a cyclone and reduce the wind resistance and wind noise.

[0103] In some embodiments, the dust-gas separation structure 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 1122 at one end away from the air inlet pipe 113, and the fan assembly 120 is connected to the air outlet 1122, and the filter 1145 is arranged between the flow guide 1142 and the fan assembly 120.

[0104] It can be understood that the cyclone gas flow from the cyclone outlet 1132 can be thrown out to the inner wall of the dust collecting shell 112 through the flow guide 1142, thereby having a better dust-gas separation effect, and the fine dust remaining in the gas flow can be filtered by the filter 1145, thereby ensuring the cleanliness of the gas flow entering the fan assembly 120 and being discharged.

[0105] 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, and 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 gas flow from 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.

[0106] 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 gas flow 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 gas flow and make the dust and sundries separated and treated under the centrifugal force to sink downward.

[0107] For example, the flow guide ball 1144 is coaxially arranged with the air inlet pipe 113, thereby ensuring the smoothness of the gas flow from the cyclone outlet 1132, and avoiding the generation of turbulence in the cyclone outlet 1132.

[0108] In some embodiments, the inner wall of the cyclone outlet 1132 is surrounded 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.

[0109] It can be understood that the cyclone outlet 1132 can form a horn-shaped structure for increasing the flow area of the cyclone outlet 1132, which is conducive to the diffusion of the gas flow from the cyclone outlet 1132, thereby more efficiently separating 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 gas flow can increase the flow rate while diffusing to the four directions, thereby increasing the centrifugal force of the dust and sundries during the dust-gas separation in the cyclone.

[0110] 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.

[0111] In some embodiments, the cyclone support is provided with a ventilation hole, and the ventilation hole communicates the dust collecting cavity 111 and the air outlet 1122. 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 can be prevented from being directly discharged from the cyclone outlet 1132 into the ventilation hole.

[0112] 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.

[0113] 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 flowing out of the dust collecting assembly 110.

[0114] 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 and the like, and the embodiments of the present application do not make specific limitation thereto.

[0115] In the embodiments of the present application, the dust collecting shell 112 and the air inlet pipe 113 can be coaxially arranged. The dust collecting shell 112 and the air inlet pipe 113 can form an inner-outer sleeving structure, so as to ensure that the dust collecting cavity 111 is large enough, reduce the radial dimension of the dust collecting assembly 110 as a whole, and achieve the design purpose of light weight.

[0116] Exemplarily, the air inlet pipe 113 can include a pipe body 1133 and a connecting portion 1134 connected to an end of the pipe body 1133, the pipe body 1133 is located in the dust collecting shell 112, an outer wall of the connecting portion 1134 is provided with an external thread 1135, an inner wall of the dust collecting shell 112 is provided with an internal thread 1121, the external thread 1135 is screwed with the internal thread 1121, which can ensure the connection reliability of the air inlet pipe 113 and the dust collecting shell 112, and avoid ensuring good sealing performance at the connection position.

[0117] Exemplarily, the connecting portion 1134 is provided with a stepped portion below the external thread 1135, the stepped portion abuts against an end face of the first end of the dust collecting shell 112, the stepped portion can limit the screwing depth of the connecting portion 1134 and the dust collecting shell 112, which can improve the sealing performance of the connection position of the dust collecting shell 112 and the air inlet pipe 113.

[0118] It should be noted that the air inlet pipe 113 and the dust collecting shell 112 can also be connected by ultrasonic welding, induction welding, glue bonding and the like, which are not limited in the embodiments of the present application.

[0119] In some embodiments, an outer wall of the air inlet pipe 113 is provided with a turbulence portion 1136 extending towards the inner wall of the dust collecting shell 112.

[0120] It can be understood that when the airflow enters the dust collecting cavity 111 and rotates to throw out the dust and sundries, the turbulence portion 1136 can block the airflow and the dust and sundries, so as to accelerate the falling of the dust and sundries, and prevent the settled dust from being lifted by the airflow.

[0121] Exemplarily, the turbulence portion 1136 can be arranged at the top or the middle position of the air inlet pipe 113. The turbulence portion 1136 can be welded with the outer wall of the air inlet pipe 113.

[0122] In some embodiments, the turbulence portion 1136 can be multiple, and the multiple turbulence portions 1136 are spaced apart around the circumference of the air inlet pipe 113. An end of the turbulence portion 1136 away from the air inlet pipe 113 abuts against the inner wall of the dust collecting shell 112, so as to have a better turbulence effect and further accelerate the falling of the dust and sundries into the dust collecting cavity 111.

[0123] It should be noted that when the air inlet pipe 113 and the dust collecting shell 112 are assembled, the air inlet pipe 113 is inserted into the inside of the dust collecting shell 112, the connecting portion 1134 at the lower end is screwed with the dust collecting shell 112, and the turbulence portion 1136 at the upper end abuts against the inner wall of the dust collecting shell 112, so as to maintain the stability of the air inlet pipe 113 in the dust collecting shell 112, and avoid radial displacement or shaking of the air inlet pipe 113.

[0124] In some embodiments, the diameter of the radial section of the dust collection assembly 110 is 35mm-50mm. The overall radial size of the dust collection assembly 110 can be controlled within a reasonable range while ensuring that the dust collection cavity 111 has a large enough dust collection space, so that the dust collection assembly 110 forms an elongated rod structure as part of the cleaning device 100, achieving lightweight design of the product.

[0125] It can be understood that the diameter of the radial section of the dust collection assembly 110 can be approximately equal to the radial section size of the outer contour of the dust collection shell 112. For example, the cross-sectional shape of the dust collection shell 112 can be circular, or the cross-sectional shape of the dust collection shell 112 can be elliptical or other regular polygons, which are not limited in the embodiments of the present application.

[0126] For example, the specific numerical value of the diameter of the radial section of the dust collection assembly 110 can include but is not limited to 35mm, 36mm, 40mm, 45mm, 49mm, 50mm, which are not limited in the embodiments of the present application.

[0127] In some embodiments, the dust collection assembly 110 further comprises a dust collection bin cover 115. The sidewall of the dust collection shell 112 is provided with a dust discharge port, which communicates the dust collection cavity 111 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.

[0128] It can be understood that when the cleaning device is in normal use, the dust collection bin cover 115 closes the dust discharge port to prevent dust leakage. When the dust collection cavity 111 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 111 from the dust discharge port.

[0129] It should be noted that in the dust collection assembly 110 provided by the embodiments of the present application, the dust collection cavity 111 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 111 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 assembly 110 from the cleaning device, improving the convenience of cleaning the dust collection cavity 111.

[0130] The structure of the fan assembly 120 will be described in detail below.

[0131] Figure 13 The structure of the fan assembly in the cleaning device provided by the embodiments of the present application is shown in the schematic diagram.

[0133] It can be understood that the first buffer 123 and the second buffer 124 can play a good damping and buffering effect on the fan unit 122. When the fan unit 122 is running, the vibration of the fan unit 122 is avoided from being transmitted to the fan housing 121, and the noise of the fan assembly 120 when running is reduced.

[0134] For example, the first buffer 123 and the second buffer 124 can both be elastic components of rubber or silicone, and the first buffer 123 and the second buffer 124 can both be annular gasket structures. The specific material and shape of the first buffer 123 and the second buffer 124 are not limited in the embodiment of the application.

[0135] For example, the cross-sectional shape of the fan housing 121 can be circular, or the cross-sectional shape of the dust collection housing 112 can be oval or other regular polygons. The embodiment of the application does not make specific limitations on this.

[0136] For example, the diameter of the radial cross-section of the fan housing 121 is 35mm-50mm. The specific value of the diameter of the radial cross-section of the fan housing 121 can include but is not limited to 35mm, 36mm, 40mm, 45mm, 49mm, 50mm, and the embodiment of the application does not make specific limitations on this.

The battery unit is used to power the electric devices such as the electric control board and the fan assembly 120, and the electric control board can control the operation of the fan assembly 120.

[0142] In some embodiments, the battery unit can be multiple, and the multiple battery units are arranged in sequence along the axial direction of the battery rod body in the battery cavity, which can ensure the uniform distribution of the weight of the battery unit.

[0143] For example, the multiple battery units can be arranged in sequence in series. The user can replace the battery unit by opening the battery cavity.

[0144] In some embodiments, a wiring cavity is arranged on the side of the battery cavity along the radial direction of the battery rod body, and a switch unit is arranged at the end of the battery rod body away from the fan assembly 120.

In this way, the flexibility of the suction cup 200 is ensured, and the smoothness of the airflow from the suction cup 200 into the dust suction device 100 is improved.
