The fan is used to generate negative pressure, so that the suction port on the suction head generates suction force to realize the dust collection function. The inhaled dust can be stored in the dust collecting box. The dust collecting box and the fan are usually arranged on the top of the operation body.

[0047] However, at present, when the dust collector cleans the dust collecting box, the dust collecting box needs to be detached from the dust collector, and the dust collecting box is opened separately, for example, the filter part is taken out first, and then the dust and sundries are poured out. The process of cleaning the dust collecting box is complicated.

[0048] In order to solve the above technical problems, the dust collecting assembly and the cleaning equipment provided by the embodiments of the present application are provided, the dust collecting assembly is used in the cleaning equipment, the dust collecting cavity is formed by inserting the air inlet pipe into the dust collecting shell and using the space between the air inlet pipe and the dust collecting shell, so that when it is necessary to clean the dust and sundries in the dust collecting cavity, only the dust outlet on the outer wall of the shell needs to be opened, without the need to take the dust collecting assembly from the cleaning equipment, thereby improving the convenience of cleaning the dust collecting cavity.

[0049] In order to facilitate understanding, first, the application scenario of the cleaning equipment provided by the embodiments of the present application is described.

[0050] The cleaning equipment provided by the embodiments of the present application 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.

[0051] Figure 1 The structure diagram of the dust collecting assembly provided by the embodiments of the present application is shown in the figure; Figure 2 The exploded view of the dust collecting assembly provided by the embodiments of the present application is shown in the figure; Figure 3 The outer wall diagram of the dust collecting shell in the dust collecting assembly provided by the embodiments of the present application is shown in the figure; Figure 4 The front view of the dust collecting bin cover in the dust collecting assembly provided by the embodiments of the present application is shown in the figure.

[0052] Referring to Figures 1 to 4 As shown in the figure, the present application provides a dust collecting assembly 100, which can be applied to a cleaning equipment, the cleaning equipment has a dust collection function, dust gas sucked into the dust collecting assembly 100 can be separated, and dust and sundries can be separated and collected in the dust collecting assembly 100.

[0053] The dust collecting assembly 100 provided by the present application includes a dust collecting shell 112, an air inlet pipe 113 and a dust collecting bin cover 115, the air inlet pipe 113 is at least partially inserted into the dust collecting shell 112, the outer wall of the air inlet pipe 113 and the inner wall of the dust collecting shell 112 form a dust collecting cavity 111, and the air inlet pipe 113 is in communication with the dust collecting cavity 111.

[0054] It can be understood that the inner wall of the dust collection shell 112 forms the dust collection cavity 111 outside the air inlet pipe 113, fully utilizes the space in the dust collection shell 112, reduces the volume of the entire dust collection assembly 100, forms a long barrel structure, and thus when applied to the cleaning equipment, the overall weight of the cleaning equipment can be reduced, the overall center of the cleaning equipment can be lowered, the weight can be avoided to be concentrated on the holding end of the cleaning equipment, and the user experience is improved.

[0055] In some embodiments, the sidewall of the dust collection shell 112 is provided with a dust discharge port 1120, and the dust discharge port 1120 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 1120 to open or close the dust discharge port 1120.

[0056] It can be understood that when the cleaning equipment is normally used, the dust discharge port is closed by the dust collection bin cover 115 to avoid 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 sundries in the dust collection cavity 111 from the dust discharge port.

[0057] It should be noted that in the dust collection assembly 100 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 sundries in the dust collection cavity 111 need to be cleaned, the dust discharge port 1120 on the outer wall of the shell can be opened, without the need to remove the dust collection assembly 100 from the cleaning equipment, thereby improving the convenience of cleaning the dust collection cavity 111.

[0058] The specific setting position of the dust discharge port 1120 and the specific structure of the dust collection bin cover 115 will be described in detail below.

[0059] Please continue to refer to Figures 1 to 4 As an optional embodiment, the dust discharge port 1120 is located on the sidewall of the dust collection shell 112 close to one end of the bottom of the dust collection cavity 111. In this way, the dust and sundries settled at the bottom of the dust collection shell 112 are more easily poured out when the dust discharge port 1120 is opened.

[0060] It can be understood that by arranging the dust discharge port 1120 on the sidewall of the dust collection shell 112 close to one end of the bottom of the dust collection cavity 111, when the dust is poured out, the dust collection assembly 100 only needs to be tilted, which can prevent the dust and sundries from entering the air inlet pipe 113.

[0061] In some embodiments, the air inlet pipe 113 is inserted into and connected with the dust collecting shell 112 from the bottom end of the dust collecting shell 112; the air inlet pipe 113 is provided with a cyclone outlet 1132 at one end inserted into the dust collecting shell 112, and the dust discharging port 1120 is located at one end of the dust collecting cavity 111 away from the cyclone outlet 1132, so that the dust collecting cavity 111 can have a large enough dust storage space to avoid dust overflowing into the air inlet pipe 113.

[0062] It can be understood that the dust gas flowing out of the cyclone outlet 1132 at the top of the air inlet pipe 113 can realize the separation of dust and gas flow by centrifugal force under the action of cyclone, and the separated dust is thrown to the inner wall of the dust collecting shell 112 and then sinks to the bottom of the dust collecting cavity 111 provided with the dust discharging port 1120.

[0063] Figure 5 A cross-sectional view of the dust collecting assembly provided by the embodiments of the present application is provided.

[0064] Please refer to Figures 1 to 5 In some embodiments, the dust collecting cover 115 can include a clamping portion 1151, a connecting portion 1152 and a blocking portion 1153, the connecting portion 1152 is connected between the clamping portion 1151 and the blocking portion 1153, the sidewall of the dust collecting shell 112 is provided with a clamping hole 1123, the clamping portion 1151 is clamped with the clamping hole 1123, and the blocking portion 1153 is in butt joint with the dust discharging port 1120.

[0065] It can be understood that the clamping portion 1151 allows the dust collecting cover 115 to be fixed on the dust collecting shell 112, so as to avoid the loss of the dust collecting cover 115. The connecting portion 1152 is connected, so that the blocking portion 1153 can open or close the dust discharging port 1120 very conveniently.

[0066] For example, the connecting portion 1152 is flexible, so that the blocking portion 1153 can be bent through the connecting portion 1152 to open the dust discharging port 1120. The user can open or close the dust discharging port 1120 by pulling or pressing the blocking portion 1153, which has better operation convenience

[0069] In some embodiments, the blocking portion 1153 is provided with a clamping groove 1153a around the circumferential outer side thereof, and when the blocking portion 1153 is in abutment with the dust discharging port 1120, the circumferential inner edge of the dust discharging port 1120 is clamped in the clamping groove 1153a. The clamping groove 1153a is provided with a second stepped portion 1153b at the side directed to the inside of the dust collecting shell 112, which abuts against the inner wall of the dust collecting shell 112, so as to improve the reliability of the sealing of the dust discharging port 1120 by the blocking portion 1153 and avoid dust leakage.

[0070] For example, the clamping portion 1151, the connecting portion 1152 and the blocking portion 1153 can be an integrally formed piece. The dust collecting bin cover 115 can be an elastic piece made of rubber, silica gel or the like, or can be a plastic-coated piece made of rubber and plastic, and the embodiments of the present application do not make specific limitations in this regard.

[0071] In some embodiments, the blocking portion 1153 is flexible, and the blocking portion 1153 is provided with a groove 1153c at one end directed to the outside of the dust collecting shell 112, so that the blocking portion 1153 can be elastically deformed into the groove 1153c by being pressed, and the blocking portion 1153 can be taken out of the dust discharging port 1120, improving the convenience of opening the dust discharging port 1120.

[0072] It can be understood that the profile shape of the blocking portion 1153 matches the shape of the dust discharging port 1120, and the groove 1153c provided in the blocking portion 1153 can form a thin-walled structure, which can realize reliable clamping with the dust discharging port 1120 by using the clamping groove 1153a, and make it convenient for the user to open the dust discharging port 1120 by using the thin-walled structure.

[0073] Figure 6 A cross-sectional view of the air inlet pipe in the dust collecting assembly provided by the embodiments of the present application; Figure 7 An end view of the air inlet pipe in the dust collecting assembly provided by the embodiments of the present application.

[0074] Please refer to Figure 6 and Figure 7 , and combine with Figures 1 to 5In some embodiments, the air inlet pipe 113 can include a pipe body 1133 and a connecting section 1134, the connecting section 1134 is sealingly connected with the bottom end of the dust collecting shell 112, and the pipe body 1133 is connected with the connecting section 1134 and is inserted into the dust collecting shell 112. The end of the pipe body 1133 connected with the connecting section 1134 is provided with an air inlet 1131, and the end of the pipe body 1133 towards the inside of the dust collecting shell 112 is in communication with the inside of the dust collecting shell 112. In this way, the compactness of the overall structure of the dust collecting assembly 100 can be improved, and the radial profile size of the dust collecting assembly 100 can be reduced while having a larger dust collecting space.

[0075] It can be understood that the connecting section 1134 is sealingly connected with the bottom of the dust collecting shell 112, which can ensure the airtightness of the dust collecting cavity 111 and prevent dust from leaking out from the connection position of the bottom of the air inlet pipe 113 and the dust collecting shell 112.

[0076] 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 section 1134 can be provided with a second threaded portion 1135, the first threaded portion 1121 is screwed with the second threaded portion 1135 to achieve threaded sealing. The connecting section 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 threaded screwing depth of the connecting section 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.

[0077] In some embodiments, the dust collecting assembly 100 further includes a flow guide assembly 114, the air inlet pipe 113 is connected with the dust collecting shell 112, the air inlet pipe 113 is at least partially inserted into the dust collecting shell 112, and the outer wall of the air inlet pipe 113 and the inner wall of the dust collecting shell 112 surround to form the dust collecting cavity 111. The dust collecting cavity 111 is used for storing separated dust and sundries.

[0078] In some embodiments, the air inlet pipe 113 is provided with an air inlet 1131 and a cyclone outlet 1132, the air inlet 1131 is towards the outside of the dust collecting shell 112, and the cyclone outlet 1132 is towards 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 away from the air inlet pipe 113, and the flow guide assembly 114 is opposite to the cyclone outlet 1132 and is at least partially located in the air inlet pipe 113 to form a cyclone flow channel between the flow guide assembly 114 and the inner wall of the air inlet pipe 113.

[0079] 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 passage between the air inlet pipe 113 and the flow guide assembly 114. The flow guide assembly 114 can guide the dust gas flow, so that the dust and impurities can be separated by rotation and centrifugal motion.

[0080] It should be noted that in the dust collection assembly 100 provided by the embodiment of the present application, the inner wall of the dust collection shell 112 forms a dust collection cavity 111 outside the air inlet pipe 113, fully utilizes the space in the dust collection shell 112, and sets the flow guide assembly 114 at the top cyclone outlet 1132 of the air inlet pipe 113 to separate the dust gas at the end of the air inlet pipe 113. The dust gas separation effect is good, the volume of the entire dust collection assembly 100 is reduced, and a long barrel structure is formed. Therefore, when applied to the cleaning device, the overall weight of the cleaning device can be reduced, the overall center of the cleaning device can be lowered, the weight can be avoided to be concentrated on the holding end of the cleaning device, and the user experience can be improved.

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

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

[0083] For example, the first flow guide piece 1141 can include a plurality of flow guide blades 1141a arranged at intervals around the central axis of the air inlet pipe 113. The plurality of flow guide blades 1141a can form a plurality of flow channels, improve the efficiency and flow rate of the airflow in the air inlet pipe 113 to form a cyclone, and further increase the centrifugal force of the dust and impurities thrown out during dust gas separation, thereby having better dust gas separation effect and efficiency.

[0084] In some embodiments, the guide assembly 114 can include a second guide member 1142 located between the cyclone outlet 1132 and the air outlet 1122. The second guide member 1142 can include a guide bracket 1143 connected with the inner wall of the dust collection shell 112 and a guide ball 1144 connected with the guide bracket 1143, and at least part of the structure of the 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 to the inner wall of the dust collection shell 112, thereby improving the dust-gas separation efficiency. The air outlet area of the cyclone outlet 1132 can be controlled by the 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, thereby maintaining the dust-gas separation effect.

[0085] It can be understood that the guide bracket 1143 plays a role in fixing the guide ball 1144, 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 guide ball 1144, and the guide bracket 1143 can block the airflow and make the dust and sundries separated by centrifugal force sink downwards.

[0086] In some embodiments, the guide bracket 1143 is provided with a ventilation hole 1143a communicating the dust collection cavity 111 and the air outlet 1122. The ventilation hole 1143a is arranged close to the connection position of the guide ball 1144 and the cyclone bracket. The ventilation hole 1143a is used for the airflow after dust-gas separation to flow out, and the ventilation hole 1143a is arranged close to the root of the guide ball 1144, so that the ventilation hole 1143a is as close as possible to the center position of the guide bracket 1143, which can prevent the airflow carrying dust from being directly discharged from the cyclone outlet 1132 into the through hole.

[0087] It should be noted that the cyclone bracket can be connected with the inner wall of the dust collection shell 112 by welding, or the cyclone bracket can be fixed relative to the inner wall of the dust collection shell 112 by clamping and limiting.

[0088] In some embodiments, the outer wall of the air inlet pipe 113 is provided with a turbulence portion 1136 protruding from the outer surface of the air inlet pipe 113 and abutting against the inner wall of the dust collection shell 112.

[0089] It can be understood that when the airflow enters the dust collection cavity 111 to rotate and throw out dust and sundries, the turbulence portion 1136 can block the airflow and dust and sundries, thereby accelerating the falling of the dust and sundries. Moreover, the airflow blocked by the guide bracket 1143 will rebound downwards, and the turbulence portion 1136 can prevent the rebounding airflow from carrying the already settled dust.

[0090] In some embodiments, a filter 1145 is arranged in the dust collection housing 112, and is arranged between the flow guide support 1143 and the fan assembly 120. The filter 1145 may, for example, comprise a high efficiency particulate air filter (HEPA filter), and can filter dust impurities of micron level to ensure clean air is discharged.
