[0054] In order to make the purposes, technical solutions and advantages of the embodiments of the application more clear, the technical solutions in the embodiments of the application will be described clearly and completely in the following with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are part of the embodiments of the application, not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.

[0055] 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, and a user holds and pushes and pulls the operation main body through the handle, so as to drive the suction head to move. The operation main body is provided with a dust collection box and a fan and the like, the fan is used for generating negative pressure to realize the dust collection function, and the dust collection box is used for filtering and collecting the dust sucked in, and the dust collection box and the fan and the like are generally arranged on the top of the operation main body.

[0056] However, the assembly structure of the operation main body of the current dust collector is complex, the dust collection box is generally a structure independent of the operation main body, and the weight of the fan and the dust collection box is concentrated on the top of the operation main body, so that the weight of the hand holding position is too large when the user performs the cleaning operation, and the operation is inconvenient in the use process.

[0057] In order to solve the above technical problems, the dust collection device and the cleaning equipment provided by the embodiments of the present application are coaxially assembled to form an elongated rod-shaped structure, which realizes the lightweight effect of the dust collection device. The components are arranged in sequence along the axial direction, the axial weight distribution of the overall structure of the dust collection device is more uniform, the weight of the hand holding position is reduced in the use process, and the use operation is more convenient and labor-saving.

[0058] In order to facilitate understanding, first, the application scenario of the dust collection device and the cleaning equipment provided by the embodiments of the present application is described.

[0059] The dust collection device provided by the embodiments of the present application is applied to the cleaning equipment, the cleaning equipment can have a dust collection function, including but not limited to a dust collector, a scrubber, a dust and mop integrated machine and the like, and the cleaning equipment can be applied to household cleaning, and can also be applied to ground cleaning in other indoor or outdoor scenes, and the specific product type to which the dust collection device is applied and the specific application scenario of the cleaning equipment are not limited.

[0060] Figure 1 The structure diagram of the dust collection device provided by the embodiments of the present application is shown in the figure; Figure 2 The exploded view of the dust collection device provided by the embodiments of the present application is shown in the figure.

[0061] Referring to Figure 1 and Figure 2 The dust collection device 100 provided by the embodiments of the present application comprises a dust collection assembly 110, a fan assembly 120 and a battery assembly 130. The axial two ends of the dust collection assembly 110 are respectively provided with an air inlet 1131 and an air outlet 1121, the fan assembly 120 is connected to one end of the dust collection assembly 110 provided with the air outlet 1121, and the fan assembly 120 communicates with the air outlet 1121. The battery assembly 130 is connected to one end of the fan assembly 120 away from the dust collection assembly 110.

[0062] The dust collection assembly 110 is used for dust gas flow and dust gas separation, and stores dust and sundries in the dust collection assembly 110. The fan assembly 120 is used to generate airflow, so that the air inlet 1131 of the dust collection assembly 110 can form a negative pressure, thereby realizing the dust suction function. The battery assembly 130 is used to provide power for the fan assembly 120, so that the dust suction device 100 can be used in the cleaning equipment whether it is plugged in or not.

[0063] In some embodiments, the dust collection assembly 110, the fan assembly 120, and the battery assembly 130 are coaxially arranged. In this way, along the axial direction of the dust suction device 100, the dust collection assembly 110, 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 dust suction device 100 forms an elongated rod-shaped structure.

[0064] It can be understood that the dust collection assembly 110 provides a channel for dust gas flow while forming a separation and storage space for dust and sundries. The fan assembly 120 is located at the middle position of the dust suction device 100. Compared with the prior art in which the fan is arranged at the top end, the end weight of the dust suction device 100 in the embodiment of the application is smaller, and the top of the dust suction device 100 forms a rod-shaped structure by the battery assembly 130, which is convenient for the user to hold during use and more labor-saving in operation.

[0065] It should be noted that the dust suction device 100 provided by the application can play the role of an operating body when applied to the cleaning equipment, and the coaxially assembled dust collection assembly 110, fan assembly 120, and battery assembly 130 form a rod-shaped structure as a whole for the user to hold during use. Since the three assemblies are arranged in sequence, the axial weight distribution of the overall structure of the dust suction device 100 is more uniform, the structure is more compact and small, the lightweight effect of the dust suction device 100 is achieved, the weight of the hand holding position during use is reduced, and the use experience is improved.

[0066] The structures of the dust collection assembly 110, the fan assembly 120, and the battery assembly 130 will be described in detail below.

[0067] Figure 3 A cross-sectional view of the dust collection assembly in the dust suction device provided by the embodiment of the application; Figure 4 An exploded view of the dust collection assembly in the dust suction device provided by the embodiment of the application,

[0068] Please refer to Figure 3 and Figure 4 in combination with Figure 1 and Figure 2In a possible implementation, the dust collection assembly 110 can include a dust collection shell 112, an air inlet pipe 113, and a filter 115. The dust collection shell 112 has a dust collection cavity 111, the air inlet pipe 113 is connected to the dust collection shell 112, and the filter 115 is arranged in the dust collection shell 112.

[0069] The air inlet pipe 113 can suck external dust gas into the dust collection shell 112 through the negative pressure air flow formed by the fan assembly 120. The dust collection shell 112 forms the shell structure of the dust collection assembly 110 as the main structure, the filter 115 filters the air flow after the dust gas is separated in the dust collection shell 112, and the filtered air flow flows from the dust collection shell 112 to the fan assembly 120.

[0070] It can be understood that the dust collection shell 112 forms a space for storing dust and sundries, the dust and sundries can be directly sucked into the dust collection cavity 111 through the air inlet pipe 113, and the air flow is filtered by the filter 115 when flowing out, so that a dust collection box does not need to be separately arranged, and the dust storage structure of the dust collection device 100 is simplified.

[0071] In some embodiments, the dust collection shell 112, the air inlet pipe 113, and the filter 115 are coaxially arranged. The dust collection shell 112 forms a long barrel structure, the air inlet pipe 113 is inserted into the dust collection shell 112, and the filter 115 is correspondingly arranged at the end of the air inlet pipe 113. In this way, the components of the dust collection assembly 110 are coaxially arranged, the weight distribution of the dust collection assembly 110 as a whole can be optimized, and the operation feeling of use is improved when the dust collection assembly 110 is applied to a cleaning device.

[0072] It should be noted that the dust collection shell 112 is sleeved with the air inlet pipe 113, the dust collection cavity 111 can be formed by using the space between the dust collection shell 112 and the air inlet pipe 113, the space utilization of the dust collection assembly 110 is improved, and the miniaturization and light weight design of the dust collection device are realized.

[0073] For example, the air inlet pipe 113 is at least partially inserted into the dust collection shell 112, the air inlet 1131 is arranged on the air inlet pipe 113, and the air inlet pipe 113 is in communication with the dust collection cavity 111. The air outlet 1121 is located at one end of the dust collection shell 112 facing the fan assembly 120, and the filter 115 is arranged opposite the air outlet 1121. In assembly, the air inlet pipe 113 can use the internal space of the dust collection shell 112 to improve the space utilization.

[0074] For example, the filter 115 can include a high efficiency particulate air filter (HEPA filter), and the filter 115 can filter dust impurities of micron level, thereby ensuring the cleanliness of the air flowing out of the dust collection assembly 110.

[0075] It should be noted that the air inlet pipe 113 and the filter 115 can be detachably connected to the dust collection shell 112 in a 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 limitations in this regard.

[0076] In some embodiments, the dust collection assembly 110 can further include a flow guide 114, which is arranged in the dust collection shell 112. The air inlet pipe 113 is provided with a cyclone outlet 1132 at an end away from the air inlet 1131, the cyclone outlet 1132 is in communication with the dust collection cavity 111, and the flow guide 114 is opposite to the cyclone outlet 1132.

[0077] It can be understood that when the airflow with dust and sundries in the air inlet pipe 113 is discharged from the cyclone outlet 1132, the dust and sundries can be separated by sedimentation by using centrifugal force after being guided by the flow guide 114, thereby improving the collection efficiency of the dust and sundries.

[0078] It should be noted that when the airflow of the cyclone outlet 1132 flows out, a cyclone airflow can be formed, thereby generating centrifugal force to separate impurities in the airflow. The impurities with relatively large weight and particles are thrown outward to the inner wall of the dust collection shell 112 and then settle in the dust collection cavity 111.

[0079] The flow guide 114 can include a flow guide vane arranged in the cyclone outlet 1132. The flow guide vane 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 be rotated and discharged from the cyclone outlet 1132, thereby separating the dust and sundries from the airflow by using centrifugal force, and improving the efficiency of dust-air separation.

[0080] For example, the flow guide vane can be welded to the inner wall of the cyclone outlet 1132. The surface of the flow guide vane can be arc-shaped to ensure the smoothness of the airflow forming a cyclone and reduce wind resistance and wind noise.

[0081] 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 dust collection device 100, and the lightweight design of the product is achieved.

[0082] It can be understood that the diameter of the radial section of the dust collection assembly 110 can be approximately equal to the outer contour radial section size 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 also be elliptical or other regular polygons, and the embodiments of the present application do not make specific limitations in this regard.

[0083] Exemplarily, the specific numerical value of the diameter size of the radial cross section of the dust collection assembly 110 can include, but is not limited to, 35 mm, 36 mm, 40 mm, 45 mm, 49 mm, 50 mm, and the like, without specific limitation in the embodiments of the present application.

[0084] Exemplarily, the air inlet pipe 113 can include a pipe body 1133 and a connecting portion 1134 connected to the end of the pipe body 1133. The pipe body 1133 is located in the dust collection shell 112, and the outer wall of the connecting portion 1134 is provided with external threads. The inner wall of the dust collection shell 112 is provided with internal threads, and the external threads are screwed with the internal threads. The connection reliability of the air inlet pipe 113 and the dust collection shell 112 can be ensured, and good sealing performance at the connection position can be ensured.

[0085] In some embodiments, the outer wall of the air inlet pipe 113 is provided with a turbulence portion 1135 extending towards the inner wall of the dust collection shell 112.

[0086] It can be understood that when the airflow enters the dust collection cavity 111 and rotates to throw out dust and sundries, the turbulence portion 1135 can block the airflow and dust and sundries as the airflow rebounds and sinks, thereby accelerating the falling of dust and sundries and preventing the settled dust from being lifted by the airflow.

[0087] Exemplarily, the turbulence portion 1135 can be provided at the top or middle position of the air inlet pipe 113. The turbulence portion 1135 can be welded with the outer wall of the air inlet pipe 113.

[0088] In some embodiments, the turbulence portion 1135 can be multiple, and the multiple turbulence portions 1135 are spaced apart around the circumference of the air inlet pipe 113. The end of the turbulence portion 1135 away from the air inlet pipe 113 abuts against the inner wall of the dust collection shell 112, so that better turbulence effect can be achieved, further accelerating the falling of dust and sundries into the dust collection cavity 111.

[0089] It should be noted that when the air inlet pipe 113 and the dust collection shell 112 are assembled, 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 1135 at the upper end abuts against 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 radial displacement or shaking of the air inlet pipe 113.

[0090] In some embodiments, the dust collection assembly 110 further includes a dust collection bin cover 116. The sidewall of the dust collection shell 112 is provided with a dust discharge port 1122, and the dust discharge port 1122 communicates the dust collection cavity 111 with the outside of the dust collection shell 112. The dust collection bin cover 116 is connected with the dust collection shell 112, and the dust collection bin cover 116 is movably arranged relative to the dust discharge port 1122 to open or close the dust discharge port 1122.

[0091] It can be understood that when the cleaning device is normally used, the dust collection bin cover 116 closes the discharge port to avoid dust leakage. When the dust collection cavity 111 needs to be cleaned, the dust collection bin cover 116 can be opened to pour out the dust and sundries in the dust collection cavity 111 from the discharge port.

[0092] It should be noted that in the dust collection assembly 110 provided by the embodiment 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 sundries in the dust collection cavity 111 need to be cleaned, the dust discharge port 1122 on the outer wall of the shell can be opened, without the need to remove the dust collection assembly 110 from the cleaning device, thereby improving the convenience of cleaning the dust collection cavity 111.

[0093] The structure of the fan assembly 120 will be described in detail below.

[0094] Figure 5 The cross-sectional view of the fan assembly in the dust collection device provided by the embodiment of the present application.

[0095] Please refer to Figure 5 , and in combination with Figures 1 to 3 In a possible implementation manner, the fan assembly 120 can include a fan shell 121, a fan unit 122, a first buffer 123 and a second buffer 124, the fan shell 121 is connected to the air outlet 1121, the fan unit 122 is arranged in the fan shell 121, the first buffer 123 and the second buffer 124 are respectively arranged at the two ends of the fan unit 122 in the axial direction, 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 shell 121.

[0096] 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 shell 121, thereby reducing the noise when the fan assembly 120 is running.

[0097] 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 present application.

[0098] For example, the cross-sectional shape of the fan shell 121 can be circular, or the cross-sectional shape of the dust collection shell 112 can also be elliptical or other regular polygons, and the present application does not make specific limitations in this regard.

[0099] Exemplarily, the diameter of the radial section of the fan housing 121 is 35mm-50mm. The specific value of the diameter of the radial section of the fan housing 121 can include, but is not limited to, 35mm, 36mm, 40mm, 45mm, 49mm, 50mm, which is not limited in the embodiments of the present application. In this way, the radial dimension 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 100, and the lightweight design of the product is realized.

[0100] The specific structure of the battery assembly 130 is described in detail below.

[0101] Figure 6 A cross-sectional view of the battery assembly in the dust collection device provided by the embodiments of the present application is provided.

[0102] Please refer to Figure 6 , combined with Figure 1 and Figure 2 , in a possible implementation, the battery assembly 130 can include a battery rod body 131, a battery unit 132 and an electric control board 133, the battery rod body 131 is connected with the fan assembly 120, the battery rod body 131 has an electric control cavity 1311 and a battery cavity 1312 distributed along the axial direction inside, the battery cavity 1312 is located on the side of the electric control cavity 1311 away from the fan assembly 120, the battery unit 132 is arranged in the battery cavity 1312, and the electric control board 133 is arranged in the electric control cavity 1311.

[0103] It can be understood that the battery rod body 131 as a support structure can separate the installation space of the battery unit 132 and the electric control board 133 along the axial direction, so as to avoid the weight concentration of the battery assembly 130 and cause the weight and size of the end of the dust collection device 100 to be too large. The battery unit 132 is used to power the electric control board 133 and the electric devices such as the fan assembly 120, and the electric control board 133 can control the operation of the fan assembly 120.

[0104] In some embodiments, the battery unit 132 can be multiple, and the multiple battery units 132 are arranged in sequence along the axial direction of the battery rod body 131 in the battery cavity 1312, which can ensure the uniform distribution of the weight of the battery unit 132.

[0105] Exemplarily, the multiple battery units 132 can be arranged in sequence in series. The user can replace the battery unit 132 by opening the battery cavity 1312.

The operation of the fan assembly 120 can be controlled through the switch unit 134, which can be pressed or touched at the end of the battery rod body 131, thereby improving the convenience of operating the switch unit 134 for the user.

[0107] For example, the switch unit 134 can be a press switch, a toggle switch, or a touch switch, and the embodiments of the present application do not make specific limitations thereto.

[0108] In some embodiments, the diameter of the radial cross section of the battery rod body 131 can be 30-40 mm. In this way, the diameter of the battery rod body 131 can be controlled within a reasonable range to ensure that the user has a good operating feel when holding it, and it is easier and more labor-saving to drag or push the cleaning equipment by holding the battery rod body 131.

[0109] For example, the diameter of the radial cross section of the battery rod body 131 can be 30-40 mm. In this way, the diameter of the battery rod body 131 can be controlled within a reasonable range to ensure that the user has a good operating feel when holding it, and it is easier and more labor-saving to drag or push the cleaning equipment by holding the battery rod body 131.

[0110] In the embodiments of the present application, the dust collection assembly 110 and the fan assembly 120, and the fan assembly 120 and the battery assembly 130 can be assembled in a detachable structure.

[0111] Please refer to Figure 1 and Figure 2 In some embodiments, an end of the fan assembly 120 towards the dust collection assembly 110 is at least partially inserted into the air outlet 1121, one of the fan assembly 120 and the dust collection assembly 110 is provided with a first clamping portion 1211, and the other is provided with a first clamping groove 1123, and the first clamping portion 1211 and the first clamping groove 1123 are clamped.

[0112] It can be understood that when the fan assembly 120 and the dust collection assembly 110 are assembled, the first clamping portion 1211 can be elastically deformed by being pressed to be inserted into or withdrawn from the first clamping groove 1123, thereby realizing the disassembly operation and improving the convenience of disassembling the fan assembly 120 and the dust collection assembly 110.

[0113] Exemplarily, the first clamping portions 1211 and the first clamping grooves 1123 can be arranged one by one in a one-to-one correspondence, and the two sides of the fan assembly 120 and the dust collection assembly 110 are each provided with the first clamping portions 1211 and the first clamping grooves 1123. When disassembling, a user only needs to hold the abutting position of the fan assembly 120 and the dust collection assembly 110 by hand, and press the first clamping portions 1211 on the two sides to realize the disassembly operation.

The dust collection shell 112 is provided with a clamping groove, the first pressing member 127 is clamped with the clamping groove, and the first elastic member 126 is configured to exert a force on the first pressing member 127 towards the clamping groove.

[0117] It can be understood that the first elastic member 126 can provide a pre-tightening force for the clamping of the first pressing member 127 in the clamping groove, so as to avoid the first pressing member 127 from being detached from the clamping groove. When it is needed to separate the fan assembly 120 from the dust collection shell 112, the first pressing member 127 can be pressed to overcome the elastic force of the first elastic member 126, so that the first pressing member 127 is withdrawn from the clamping groove, thereby realizing the disassembly of the fan assembly 120 and the dust collection shell 112. In this way, the convenience of disassembling the dust collection shell 112 and the fan assembly 120 is improved.

[0121] It can be understood that when the fan assembly 120 and the battery assembly 130 are assembled, the second clamping portion 1314 can be inserted into or withdrawn from the second clamping groove 1212 by being elastically deformed by being pressed, thereby achieving disassembly and assembly operations and improving the convenience of disassembly and assembly of the battery assembly 130 and the fan assembly 120.

[0122] For example, the second clamping portion 1314 and the second clamping groove 1212 can be one-to-one corresponding, and the two sides of the fan assembly 120 and the battery assembly 130 are provided with the second clamping portion 1314 and the second clamping groove 1212. When disassembling, only the user needs to hold the butt joint position of the fan assembly 120 and the battery assembly 130 and press the second clamping portion 1314 on both sides to achieve the disassembly operation.
