Obviously, the described embodiments are part of the embodiments of the application, not all embodiments.

[0063] The dust collector usually comprises a suction head and an operation 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 body, and a user holds and pushes and pulls the operation body through the handle, so as to drive the suction head to move. A dust collecting box is usually arranged on the operation body, and a dust-gas separation structure is correspondingly arranged on the dust collecting box, and the dust collecting box and the dust-gas separation structure are integrally arranged on the top of the operation body.

[0064] However, in the current structure of the dust collector, the dust collection box and the dust-gas separation structure are assembled at the holding position on the top of the product, which has a large volume and weight, and requires a large force to lift during use, which can easily cause fatigue of the user.

[0066] For ease of understanding, first, the application scenario of the dust collection assembly and the cleaning equipment provided by the embodiments of the present application is described.

[0067] The dust collection assembly provided by the embodiments of the present application can be applied to the cleaning equipment, which has a dust collection function, including but not limited to a dust collector, a floor washing machine, a dust 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 scenarios. The specific product type to which the dust collection device is applied, and the specific application scenario of the cleaning equipment are not limited.

[0068] Figure 1 The structure diagram of the dust collection assembly provided by the embodiments of the present application is shown in the figure; Figure 2 The exploded view of the dust collection assembly provided by the embodiments of the present application is shown in the figure; Figure 3 The cross-sectional view of the air inlet pipe in the dust collection assembly provided by the embodiments of the present application is shown in the figure.

[0069] Referring to Figures 1 to 3 As shown in the figure, the present application provides a dust collection assembly 100, which can be applied to a cleaning equipment, the cleaning equipment has a dust collection function, and the dust-gas separation can be performed when the dust gas is sucked into the dust collection assembly 100, and the dust and debris can be separated and collected in the dust collection assembly 100.

[0070] In some embodiments, the dust collection assembly 100 includes a dust collection shell 112, an air inlet pipe 113 and a flow guide assembly 114, the air inlet pipe 113 is connected with the dust collection shell 112, the air inlet pipe 113 is at least partially inserted into 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 form a dust collection cavity 111. The dust collection cavity 111 is used to store separated dust and debris.

[0071] The air inlet pipe 113 is provided with an air inlet 1131 and a cyclone outlet 1132, the air inlet 1131 is directed to the outside of the dust collecting shell 112, and the cyclone outlet 1132 is directed to the inside of the dust collecting shell 112. The flow guide assembly 114 is arranged in the dust collecting shell 112, the dust collecting shell 112 is provided with an air outlet 1122 on the side of the flow guide assembly 114 away from the air inlet pipe 113, and the flow guide assembly 114 is opposite to the cyclone outlet 1132 and at least partially arranged in the air inlet pipe 113, so that the flow guide assembly 114 and the inner wall of the air inlet pipe 113 form a cyclone flow channel.

[0072] 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, a cyclone is formed through the cyclone channel between the flow guide assembly 114 and the air inlet pipe 113. The flow guide assembly 114 can guide the flow of dust gas, so that dust and sundries can be separated by rotation and centrifugal motion.

[0073] It should be noted that in the dust collecting assembly 100 provided by the embodiment of the present application, the inner wall of the dust collecting shell 112 forms the dust collecting cavity 111 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, dust gas separation is performed at the end of the air inlet pipe 113, the volume of the entire dust collecting assembly 100 is reduced, a long barrel type structure is formed, and therefore, when applied to a cleaning device, the overall weight of the cleaning device can be reduced, the overall gravity center can be lowered, the weight can be avoided to be concentrated on the holding end of the cleaning device, and the user experience is improved.

[0074] In some embodiments, the air inlet pipe 113 is coaxially arranged with the dust collecting shell 112, and the dust collecting cavity 111 is arranged on the circumferential outer side of the air inlet pipe 113. The dust collecting cavity 111 can utilize the space on the circumferential side of the air inlet pipe 113, so that the weight distribution of the dust collecting assembly 100 in the axial direction is more uniform, and the local overloading caused by the weight concentration is avoided.

[0075] It can be understood that the height of the area in which the dust collecting cavity 111 can accommodate dust and sundries can be approximately equal to the height of the air inlet pipe 113. Since the air inlet pipe 113 is coaxially inserted into the dust collecting shell 112, the dust collecting cavity 111 fully utilizes the internal space of the dust collecting shell 112, and the gravity center of the dust collecting cavity 111 is arranged in the air inlet pipe 113 for dust gas inlet, and the space on the circumferential side is used for storing dust and sundries separated from the dust gas.

[0076] In some embodiments, the first end of the air inlet pipe 113 is connected with the first end of the dust collecting shell 112, and the air inlet 1131 is arranged at the first end of the air inlet pipe 113. The second end of the air inlet pipe 113 is inserted into the interior of the dust collecting shell 112 and extends towards the second end of the dust collecting shell 112, and the cyclone outlet 1132 is arranged at the second end of the air inlet pipe 113, and the air outlet 1122 is located at the second end of the dust collecting shell 112. The air inlet pipe 113 has a sufficient length, so that the dust collecting cavity 111 has a larger storage space, and dust overflow into the air inlet pipe 113 is avoided.

[0077] It can be understood that the air inlet pipe 113 and the dust collecting shell 112 can form an inner-outer sleeving structure. When the dust collecting cavity 111 is formed, the length direction space of the air inlet pipe 113 in the dust collecting shell 112 can be fully utilized, the space utilization is improved, and the volume of the dust collecting cavity 111 is increased.

[0078] In some embodiments, the air inlet pipe 113 can include a pipe body 1133 and a connecting portion 1134. The connecting portion 1134 is sealingly connected with the first end of the dust collecting shell 112, and the pipe body 1133 is connected with the connecting portion 1134. The air inlet 1131 and the cyclone outlet 1132 are respectively located at the two axial ends of the pipe body 1133, so that the connection reliability of the air inlet pipe 113 and the dust collecting shell 112 can be ensured. The airflow entering the air inlet pipe 113 flows along the axial direction thereof, and the smoothness of the airflow circulation is improved. The connecting portion 1134 is sealingly connected with the dust collecting shell 112 at the bottom, so that the airtightness of the dust collecting cavity 111 can be ensured, and dust leakage from the connection position of the bottom of the air inlet pipe 113 and the dust collecting shell 112 is avoided.

[0079] For example, the inner wall of the first end of the dust collecting shell 112 can be provided with a first threaded portion 1121, the outer wall of the connecting portion 1134 can be provided with a second threaded portion 1135, the first threaded portion 1121 is screwed with the second threaded portion 1135, and threaded sealing is achieved. The connecting portion 1134 is provided with a stepped portion below the second threaded portion 1135, the stepped portion abuts against the end face of the first end of the dust collecting shell 112, and the stepped portion can limit the screwing depth of the connecting portion 1134 and the dust collecting shell 112. The airtightness of the connection position of the dust collecting shell 112 and the air inlet pipe 113 can be improved.

[0080] 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, etc., and the embodiments of the present application do not make specific limitations in this regard.

[0081] In some embodiments, the flow guide assembly 114 can include a first flow guide 1141 arranged in the air inlet pipe 113 close to one end of the cyclone outlet 1132. The first flow guide 1141 is connected with the inner wall of the air inlet pipe 113, and the first flow guide 1141 extends spirally along the axial direction of the air inlet pipe 113.

[0082] It can be understood that the airflow passing through the cyclone outlet 1132 can form a cyclone under the guidance of the first flow guide 1141, so as to realize dust-gas separation by centrifugal force.

[0083] Figure 4 Structure one of the air inlet pipe in the dust collection assembly provided in the embodiments of the present application; Figure 5 Structure two of the air inlet pipe in the dust collection assembly provided in the embodiments of the present application; Figure 6 Structure three of the air inlet pipe in the dust collection assembly provided in the embodiments of the present application.

[0084] Please refer to Figures 4 to 6 , and in combination with Figures 1 to 3 , for example, the first flow guide 1141 can include a plurality of flow guide vanes 1141a, the plurality of flow guide vanes 1141a are arranged at intervals around the central axis of the air inlet pipe 113, and the plurality of flow guide vanes 1141a can form a plurality of flow channels, thereby improving the efficiency and flow rate of the airflow formed in the air inlet pipe 113 to form a cyclone, and further increasing the centrifugal force of the dust and sundries thrown out during dust-gas separation, thereby having better dust-gas separation effect and efficiency.

[0085] For example, the number of flow guide vanes 1141a can be two, three, four or more, and the embodiments of the present application do not make specific limitations thereto.

[0086] Please continue to refer to Figures 1 to 3 In some embodiments, the flow guide assembly 114 can include a second flow guide 1142 located between the cyclone outlet 1132 and the air outlet 1122. The second flow guide 1142 can include a flow guide bracket 1143 connected with the inner wall of the dust collection shell 112 and a flow guide ball 1144 connected with 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. The airflow flowing out of the cyclone outlet 1132 can be guided to rotate and diffuse towards the inner wall of the dust collection shell 112, thereby improving the dust-gas separation efficiency.

[0087] 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 upwards 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 action of centrifugal force to sink downwards.

[0088] 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 turbulence generated by the cyclone outlet 1132.

[0089] In some embodiments, the inner wall of the cyclone outlet 1132 forms 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.

[0090] 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 outward diffusion of the airflow from the cyclone outlet 1132, thereby more efficiently separating dust and gas. Since the flow guide ball 1144 is inserted in the air outlet area, the flow guide ball 1144 compresses the ventilation area of the cyclone outlet 1132, so that the airflow can increase the flow rate while diffusing to all directions, thereby increasing the centrifugal force of dust and debris during cyclone dust and gas separation.

[0091] For example, the cross-sectional dimension of the flow guide ball 1144 in the radial direction of the dust collection shell 112 first increases and then decreases from the flow guide support 1143 to the inside of the cyclone outlet 1132. The cross-sectional dimension of the part of the flow guide ball 1144 inserted into the cyclone outlet 1132 gradually decreases, which can control the air outlet area of the cyclone outlet 1132 through the flow guide ball 1144, thereby controlling the wind speed and wind pressure of the airflow, so that the airflow can continue to rotate after being discharged from the cyclone outlet 1132, maintaining the effect of dust and gas separation.

[0092] In some embodiments, the flow guide support 1143 is provided with a ventilation hole 1143a, which communicates the dust collection cavity 111 and the air outlet 1122. The ventilation hole 1143a is arranged close to the connection position of the flow guide ball 1144 and the flow guide support 1143. The ventilation hole 1143a is used for the airflow after dust and gas separation to flow out, and the ventilation hole 1143a is arranged close to the root of the flow guide ball 1144, so that the ventilation hole 1143a is as close as possible to the center position of the flow guide support 1143, which can prevent the airflow with dust from being directly discharged from the cyclone outlet 1132 into the through hole.

[0093] It should be noted that the flow guide support 1143 can be connected with the inner wall of the dust collection shell 112 by welding, or the flow guide support 1143 can be fixed relative to the inner wall of the dust collection shell 112 by clamping and limiting.

[0094] In the embodiments of the present application, the dust collection assembly 100 can further include a filter 1145 arranged between the flow guide assembly 114 and the air outlet 1122. The air inlet pipe 113, the flow guide assembly 114 and the filter 1145 are arranged in sequence along the axial direction of the dust collection shell 112. In this way, the overall volume of the dust collection assembly 100 is reduced, and the weight distribution of the dust collection assembly 100 along the axial direction is more uniform.

[0095] For example, the filter 1145 can include a High Efficiency Particulate Air Filter (HEPA Filter), which can filter dust impurities in micron level, thereby ensuring the cleanliness of the air flowing out of the dust collection assembly 100.

[0096] It should be noted that the air inlet pipe 113 and the filter 1145 can be detachably connected to the dust collection shell 112, including but not limited to threaded connection, buckle connection, elastic interference fit, etc., which are not limited in the embodiments of the present application.

[0097] In some embodiments, the outer wall of the air inlet pipe 113 is provided with a turbulence portion 1136, which protrudes from the outer surface of the air inlet pipe 113 and abuts against the inner wall of the dust collection shell 112.

[0098] It can be understood that when the air flow enters the dust collection cavity 111 and rotates to throw out the dust impurities, the turbulence portion 1136 can block the air flow and the dust impurities as the air flow rebounds and sinks, thereby accelerating the falling of the dust and impurities. Moreover, the air flow blocked by the flow guide bracket 1143 will rebound downward, and the turbulence portion 1136 can prevent the rebounding air flow from carrying the already settled dust.

[0099] For example, the turbulence portion 1136 can be provided at the top or 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.

[0100] 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. The end of the turbulence portion 1136 away from the air inlet pipe 113 abuts against the inner wall of the dust collection shell 112, thereby having a better turbulence effect and further accelerating the falling of the dust and impurities into the dust collection cavity 111.

[0101] 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 connecting portion 1134 at the lower end is threadedly connected with the dust collection shell 112, and the turbulence portion 1136 at the upper end abuts against the inner wall of the dust collection shell 112, thereby maintaining the stability of the air inlet pipe 113 in the dust collection shell 112 and avoiding the radial displacement or shaking of the air inlet pipe 113.

[0102] In some embodiments, the diameter of the radial section of the dust collection assembly 100 is 35-50 mm, which can ensure that the dust collection cavity 111 has a large enough dust collection space while controlling the overall radial size of the dust collection assembly 100 within a reasonable range, so that the dust collection assembly 100 forms an elongated rod-shaped structure as part of the main structure of the cleaning device, thereby achieving lightweight design of the product.

[0103] It is understood that the diameter of the radial section of the dust collection assembly 100 can be approximately the radial section size of the outer contour of the dust collection housing 112. For example, the cross-sectional shape of the dust collection housing 112 can be circular, or it can be elliptical or other regular polygons. This application embodiment does not specifically limit this.

[0104] For example, the specific value of the diameter of the radial section of the dust collection component 100 may include, but is not limited to, 35mm, 36mm, 40mm, 45mm, 49mm, and 50mm. This application embodiment does not specifically limit this.

[0105] In one possible implementation, the dust collection assembly 100 may further include a dust collection chamber cover 115. The side wall of the dust collection housing 112 is provided with a dust discharge port that communicates with the dust collection chamber 111. The dust collection chamber cover 115 is connected to the outer wall of the dust collection housing 112 and is positioned at the dust discharge port, so that the dust and contents in the dust collection chamber 111 can be cleaned without disassembling the dust collection assembly 100.

[0106] The dust collection chamber cover 115 is movably configured relative to the dust discharge port to open or close the dust discharge port.

[0107] Understandably, when the cleaning equipment is in normal use, the dust collection chamber cover 115 closes the dust discharge port to prevent dust from leaking out. When it is necessary to clean the dust collection chamber 111, the dust collection chamber cover 115 can be opened to pour out the dust and debris inside the dust collection chamber 111 from the dust discharge port.

[0108] It should be noted that in the dust collection assembly 100 provided in this application embodiment, a dust collection chamber 111 is formed by utilizing the space between the inside of the dust collection housing 112 and the air inlet pipe 113. Thus, when it is necessary to clean the dust and debris in the dust collection chamber 111, it is only necessary to open the dust discharge port on the outer wall of the housing, without having to remove the dust collection assembly 100 from the cleaning equipment, thereby improving the convenience of cleaning the dust collection chamber 111.

[0110] Please refer to Figures 7 to 13 , and in combination with Figures 1 to 3 , the embodiment of the present application provides a cleaning device, which comprises the dust collection assembly 100, the fan assembly 120 and the suction cup 200 in the above technical solution, and the suction cup 200 is movably connected with the dust collection assembly 100. The suction cup 200 is provided with a suction port 201 and a collection cavity 202, the suction port 201 is communicated with the collection cavity 202, and the collection cavity 202 is provided with a filter 210. The dust gas sucked from the suction port 201 can enter the collection cavity 202 and flow out after being filtered by the filter 210, and the collection cavity 202 can store the filtered dust and sundries.

[0111] Among them, the air inlet side of the fan assembly 120 is communicated with the dust collection cavity 111, the dust collection cavity 111 is communicated with the collection cavity 202, and the dust collection cavity 111 is provided with a dust gas separation structure. The dust gas flowing out of the collection cavity 202 can enter the dust collection cavity 111, and the dust gas is separated, the dust and sundries after separation are collected in the dust collection cavity 111, and the separated air is discharged from the dust collection device.

[0112] It can be understood that the suction cup 200 and the dust collection device are respectively provided with spaces for filtering and separating dust and sundries and collecting, forming a two-stage filtering structure, and twice filtering can distinguish dust and sundries of different volumes and store them in different spaces.

[0113] It should be noted that in the cleaning device provided by the present application, the dust and sundries sucked from the suction port 201 can be first filtered by the collection cavity 202, and part of the sundries with large volume is left in the collection cavity 202, and then the dust gas separation can be performed through the dust collection cavity 111, and the remaining dust and sundries are collected and stored, so that the filtering efficiency of the cleaning device for dust and sundries is improved, secondary pollution is avoided, dust and sundries can be stored in two independent spaces, the space for storing dust and sundries is larger, the user can avoid frequent cleaning, fine dust is prevented from being sucked into the human body, and the user experience is improved.

[0114] 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 respectively located at opposite sides of the collection cavity 202, the suction port 2021 is communicated with the suction port 201, and the discharge port 2022 is communicated with the dust collection cavity 111. The dust gas sucked from the 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.

[0115] It can be understood that a channel for dust and sundries to settle down can be formed between the suction port 2021 and the exhaust port 2022. When the airflow sucked from the suction port 2021 enters the collection cavity 202, part of the sundries and particles can be left in the collection cavity 202, thereby improving the collection efficiency.

[0116] In some embodiments, the filter 210 can separate the collection cavity 202 into a first chamber 202a and a second chamber 202b. The suction port 2021 communicates with the first chamber 202a, and the exhaust port 2022 communicates with the second chamber 202b. The volume of the first chamber 202a is greater than that of the second chamber 202b. When the airflow flows from the suction port 2021 to the exhaust port 2022, the filter 210 can be used for filtering, so that the sundries and particles of large volume are collected in the collection cavity 202.

[0117] It can be understood that the airflow with dust and sundries first passes through the first chamber 202a, and the sundries of large volume filtered by the filter 210 are collected and left in the first chamber 202a. The second chamber 202b provides a space and a channel for the dust and gas to converge to the exhaust port 2022.

[0118] For example, the filter 210 can be a plate structure. The filter 210 can be vertically arranged in the collection cavity 202. The edge of the filter 210 can be welded with the inner wall of the collection cavity 202, or be slidingly inserted through a sliding groove structure, or be fixedly connected through buckling. The embodiments of the present application do not make specific limitations in this regard.

[0119] In some embodiments, the filter 210 is provided with a plurality of mesh holes 211, and the plurality of mesh holes 211 are arrayed on the filter 210. The pore size of the mesh hole 211 is 0.2mm-1mm. The dust and sundries with a diameter smaller than the mesh hole 211 can enter the dust collection cavity 111 along with the airflow through the filter 210, and the sundries with a diameter larger than the mesh hole 211 are collected and left in the collection cavity 202.

[0120] It can be understood that the filter 210 can classify the dust and sundries to be collected and stored, so as to avoid the sundries of large volume entering the dust collection cavity 111, and to avoid the collection cavity 202 being filled up too quickly by too much dust and sundries.

[0121] For example, the pore size of the mesh hole 211 can include but is not limited to 0.2mm, 0.3mm, 0.5mm, 0.9mm, 1mm, etc. The embodiments of the present application do not make specific limitations in this regard.

[0122] In some embodiments, the suction port 2021 can be provided with a flexible baffle 220 arranged on the side of the suction port 2021 facing the inside of the collection cavity 202, so as to ensure one-way flow of air through the suction port 2021 and prevent dust and debris in the collection cavity 202 from leaking out of the suction port 2021.

[0123] It can be understood that when the dust and gas at the suction port 201 is sucked into the collection cavity 202 under the action of negative pressure, the flexible baffle 220 is elastically deformed under the pressure difference between the inside and outside of the collection cavity 202 and opens the suction port 2021, so that the dust and gas enters the collection cavity 202, and when the device is not started, the flexible baffle 220 returns to the initial state and blocks the suction port 2021.

[0124] For example, 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.

[0125] 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 the collection cavity 202 to facilitate cleaning of dust and debris in the collection cavity 202.

[0126] It can be understood that the collection box 240 can be installed 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 when the suction port 2021 and the discharge port 2022 are docked on the structure of the base 230.

[0127] For example, the front end of the collection box 240 along the cleaning direction of the suction cup 200 is in communication with the suction port 201, and the rear end of the collection box 240 along the cleaning direction of the suction cup 200 is in communication with the dust collection cavity 111, so as to reduce the diversion of air flow during the dust collection process, improve the smoothness of air flow circulation, and thereby improve the dust collection efficiency.

[0128] For example, 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 fixed by buckling, 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 when the box cover 242 is closed relative to the box body 241, the top end of the filter element 210 abuts or is arranged adjacent to the blocking rib, so as to separate the collection cavity 202.

[0129] The structure of the fan assembly 120 will be described in detail below.

[0130] In a possible implementation, the fan assembly 120 can include a fan housing 121 connected to the air outlet 1122, a fan unit 122 arranged in the fan housing 121, and a first buffer 123 and a second buffer 124 arranged at two axial ends of the fan unit 122 respectively, and the first buffer 123 and the second buffer 124 are both abutted between the fan unit 122 and the inner wall of the fan housing 121.

[0131] 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, and 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.

[0132] 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, and the specific material and shape of the first buffer 123 and the second buffer 124 are not limited in the embodiment of the application.

[0133] 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 also be oval or other regular polygons, and the embodiment of the application does not make specific limitations.

[0134] 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. In this way, the radial size of the fan housing 121 is controlled within a reasonable range, so that the fan assembly 120 forms an elongated rod structure as part of the dust collection device, and the lightweight design of the product is realized.

[0135] In a possible implementation, the cleaning device further includes a battery assembly 130, and the dust collection assembly 100, the fan assembly 120, and the battery assembly 130 are coaxially arranged. In this way, along the axial direction of the dust collection device, the dust collection assembly 100, the fan assembly 120, and the battery assembly 130 can be arranged in sequence, respectively forming a part of the structure, so that the overall dust collection device forms an elongated rod structure.

[0136] It can be understood that the dust collection assembly 100 provides a channel for dust gas flow while forming a separation and storage space for dust and debris by its own structure. The fan assembly 120 is located in the middle of the dust collection device. Compared with the prior art in which the fan is arranged at the top end, the weight of the end of the dust collection device is smaller in the embodiment of the application. The top of the dust collection device forms a rod-shaped structure by the battery assembly 130, which is convenient for users to hold during use and is more labor-saving to operate.

[0137] It should be noted that the dust collection device provided by the application can play the role of an operating body when applied to a cleaning device. The coaxially assembled dust collection assembly 100, fan assembly 120, and battery assembly 130 form a rod-shaped structure as a whole for users to hold during use. Due to the sequential arrangement of the three assemblies, the axial weight distribution of the overall structure of the dust collection device is more uniform, the structure is more compact and small, the lightweight effect of the dust collection device is achieved, the weight of the hand holding position during use is reduced, and the use experience is improved.

[0138] In some embodiments, the battery assembly 130 can include a battery rod body, a battery unit, and an electric control board. The battery rod body is connected with the fan assembly 120. The battery rod body has an electric control cavity and a battery cavity distributed along the axial direction inside the battery rod body. The battery cavity is located on the side of the electric control cavity away from the fan assembly 120. The battery unit is arranged in the battery cavity, and the electric control board is arranged in the electric control cavity.

[0139] It can be understood that the battery rod body, as a support structure, can separate the installation space of the battery unit and the electric control board along the axial direction, avoiding the concentration of the weight of the battery assembly 130, which causes the weight and size of the end of the dust collection device to be too large. The battery unit is used to power the electric devices such as the electric control board and the fan assembly 120. The electric control board can control the operation of the fan assembly 120.

[0140] In some embodiments, the battery unit can be multiple. 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.

[0141] 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.

[0142] In some embodiments, a wiring cavity is provided on the side of the battery cavity along the radial direction of the battery rod body. A switch unit is provided at the end of the battery rod body away from the fan assembly 120. A signal line is provided in the wiring cavity, and the signal line is configured to electrically connect the switch unit and the control board. The operation of the fan assembly 120 can be controlled by the switch unit, which only needs to press or touch the switch unit at the end of the battery rod body, thereby improving the convenience of the user in operating the switch unit.

[0143] Exemplarily, the switch unit can be a press switch, a toggle switch, or the switch unit can be a touch switch, and the embodiments of the present application do not make specific limitation thereto.

[0144] In some embodiments, the diameter of the radial section of the battery rod body can be 30-40 mm. In this way, the diameter of the battery rod body can be controlled within a reasonable range to ensure that the user has a good operation feeling when holding the battery rod body, and it is more labor-saving to drag or push the cleaning device by holding the battery rod body.

[0145] Exemplarily, the specific numerical value of the diameter of the radial section of the battery rod body can include but is not limited to 30 mm, 31 mm, 35 mm, 39 mm, 40 mm, and the embodiments of the present application do not make specific limitation thereto.

[0146] In a possible implementation, the cleaning device can further include a flexible connecting pipe 300, both ends of the flexible connecting pipe 300 are connected with the dust collection assembly 100 and the suction cup 200 respectively, and the flexible connecting pipe 300 is configured as a dust suction air duct that communicates the collection cavity 202 and the dust collection cavity 111. 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 is improved.

[0147] The present application provides a dust collection assembly and a cleaning device. The dust collection assembly includes a dust collection shell, an air inlet pipe, and a flow guide assembly. The air inlet pipe is connected with the dust collection shell and at least partially inserted into the dust collection shell. An outer wall of the air inlet pipe and an inner wall of the dust collection shell form a dust collection cavity. The air inlet pipe is provided with an air inlet and a cyclone outlet. The air inlet faces the outside of the dust collection shell, and the cyclone outlet faces the inside of the dust collection shell. The flow guide assembly is arranged in the dust collection shell. The dust collection shell is provided with an air outlet on a side away from the air inlet pipe. The flow guide assembly is opposite to the cyclone outlet and at least partially located in the air inlet pipe to form a cyclone flow channel between the flow guide assembly and the inner wall of the air inlet pipe. Therefore, when applied to the cleaning device, the overall weight of the cleaning device can be reduced, the overall gravity center can be lowered, the weight can be avoided from being concentrated on the holding end of the cleaning device, and the user experience is improved.

[0148] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
