It is understandable that the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0029] The terms "first", "second", etc. in this application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0030] See also Figure 1 , Figure 1 1 is a schematic diagram of the structure of the dust collection assembly provided in the present application. The present application provides a dust collection assembly 100. The dust collection assembly 100 can be applied to cleaning equipment, wherein the cleaning equipment can be a sweeper, a scrubber, a washer-dryer, a vacuum cleaner, etc., but is not limited thereto.

[0031] Please also read Figure 2 , Figure 2 1 is a schematic diagram of the exploded structure of the dust collection assembly provided in the present application. The dust collection assembly 100 includes a box body 10, a rotating shaft 20 and a door body 30. The box body 10 is provided with a dust collection chamber 11 and a dust discharge port 12 connected to the dust collection chamber 11. The door body 30 is provided at the dust discharge port 12 and is rotatably connected to the box body 10 through the rotating shaft 20 to open or close the dust discharge port 12.

[0032] The box body 10 is used to carry objects such as dust, dandruff, and hair. Specifically, the box body 10 also has a dust suction port connected to the dust collecting chamber 11. In some embodiments, a dust suction component is provided at the dust suction port or in the dust collecting chamber 11. When the dust suction component is working, the door body 30 closes the dust discharge port 12, and the dust suction port is in an open state. The blades of the dust suction component rotate at a high speed to form a negative air pressure in the dust collecting chamber 11, so that the dust suction port can suck objects such as dust, dandruff, and hair into the dust collecting chamber 11; when the dust suction component stops working, the dust suction port is closed to prevent the objects collected in the dust collecting chamber 11 from leaking out of the dust suction port. When it is necessary to discharge the objects temporarily stored in the dust collecting chamber 11, the door body 30 is opened to expose the dust discharge port 12, and the objects temporarily stored in the dust collecting chamber 11 can be poured out through the dust discharge port 12 by manual dumping, or can be blown out through the dust discharge port 12 by the above-mentioned dust suction component, or can be connected with the suction port of the base station to the dust discharge port 12 to suck the objects temporarily stored in the dust collecting chamber 11 into the base station. The dust suction component can be a fan, an air pump, etc., but is not limited thereto.

[0033] Please also read Figure 3 to Figure 4 , Figure 3 is a cross-sectional view of an embodiment of a dust collection assembly provided by the present application; Figure 4 yes Figure 3 The dust collecting assembly 100 further includes a torsion spring 40. The torsion spring 40 is sleeved on the rotating shaft 20. The first torque arm 41 of the torsion spring 40 is connected to one of the box body 10 and the door body 30, and the second torque arm 42 of the torsion spring 40 is supported on the other of the box body 10 and the door body 30. When the door body 30 is in an open state, the angle between the first torque arm 41 and the second torque arm 42 is greater than the angle between the first torque arm 41 and the second torque arm 42 when the door body 30 is in a closed state, so that the torsion spring 40 provides a torque for the door body 30 to rotate toward the box body 10 to close the dust discharge port 12.

[0034] The door body 30 is pivotally disposed on the box body 10 via the rotating shaft 20. The door body 30 can rotate around the rotating shaft 20 and flip between the closed position and the open position under the action of the torsion spring 40, thereby opening or closing the dust discharge port 12. The closed position is the position where the door body 30 is in a closed state, and the open position is the position where the dust discharge port 12 is opened to the maximum extent.

[0035] The torsion spring 40 includes a first torque arm 41 and a second torque arm 42. Figure 5 , Figure 5 3 is a schematic diagram of the structure of the door body and the torsion spring of the dust collecting assembly provided in the present application. The torsion spring 40 is in a natural state, that is, the torsion spring 40 is not installed on any one of the door body 30 and the box body 10, and the angle between the first torque arm 41 and the second torque arm 42 is the second angle. Figure 4When the door body 30 is successfully installed on the box body 10, that is, when the first torque arm 41 is connected to one of the box body 10 and the door body 30, the second torque arm 42 is supported on the other of the box body 10 and the door body 30, and the torsion spring 40 is sleeved on the rotating shaft 20, the torsion spring 40 undergoes elastic deformation, and when the door body 30 is in a closed state, the angle between the first torque arm 41 and the second torque arm 42 is the first angle. The torsion force of the torsion spring 40 when the angle between the first torque arm 41 and the second torque arm 42 is the first angle is greater than the torsion force when the angle is the second angle, so that the torsion spring 40 can provide the door body 30 with a torque to rotate toward the box body 10, so that the door body 30 remains in a closed state.

[0036] When the door body 30 is in the open state, the angle between the first torque arm 41 and the second torque arm 42 is greater than the angle between the first torque arm 41 and the second torque arm 42 when the door body 30 is in the closed state. For example, when the door body 30 is in a closed state, the angle between the first torque arm 41 and the second torque arm 42 is a first angle. When the door body 30 is opened relative to the box body 10, the angle between the first torque arm 41 and the second torque arm 42 gradually increases from the first angle, so that the torsion spring 40 is twisted and stores an elastic restoring force toward the box body 10. When the door body 30 is flipped to an open position, the angle between the first torque arm 41 and the second torque arm 42 reaches a maximum, and the elastic restoring force of the torsion spring 40 toward the box body 10 also reaches a maximum; the torsion spring 40 can release the stored elastic restoring force to provide the door body 30 with a torque to rotate toward the box body 10, so as to automatically drive the door body 30 to close, and keep the door body 30 in a closed state, thereby realizing that the door body 30 automatically closes the dust exhaust port 12.

[0037] In some embodiments, one of the box body 10 and the door body 30 is provided with a socket 36a for inserting the first torque arm 41, and the other of the box body 10 and the door body 30 has a supporting surface for supporting the second torque arm 42. During the installation process, the first torque arm 41 is inserted into the socket 36a reserved in one of the box body 10 and the door body 30, so that the first torque arm 41 of the torsion spring 40 is connected to one of the box body 10 and the door body 30, and then the second torque arm 42 is supported on the supporting surface of the other of the box body 10 and the door body 30, and then the rotating shaft 20 is passed through the box body 10, the door body 30 and the torsion spring 40 to successfully install the door body 30 on the box body 10, thereby omitting the step of inserting the second torque arm 42 into the other of the box body 10 and the door body 30, thereby improving the installation efficiency. During the disassembly process, it is only necessary to remove the rotating shaft 20 to separate the torsion spring 40 from the box body 10, thereby separating the box body 10 from the door body 30, and then pull out the first torque arm 41 from one of the box body 10 and the door body 30 to complete the disassembly task, thereby omitting the step of pulling out the second torque arm 42 from the other of the box body 10 and the door body 30, thereby improving the disassembly efficiency. Therefore, supporting the second torque arm 42 on the other of the box body 10 and the door body 30 can improve the convenience and efficiency of loading and unloading the torsion spring 40 on the other of the box body 10 and the door body 30, thereby increasing the convenience and efficiency of loading and unloading between the door body 30 and the box body 10, so that the convenience and efficiency of loading and unloading the torsion spring 40 and the door body 30 of the dust collecting assembly 100 are improved.

[0038] Furthermore, the embodiment of the present application can rotatably connect the door body 30 to the box body 10 through the rotating shaft 20 and the torsion spring 40. On the one hand, it can save the types and quantities of parts and simplify the structure, thereby reducing the production cost of the dust collecting component 100. On the other hand, it can also reduce the assembly process of the dust collecting component 100 and reduce the assembly difficulty of the dust collecting component 100 during the assembly process of the dust collecting component 100, thereby saving working hours and improving assembly efficiency.

[0039] In the present application, the first torque arm 41 of the torsion spring 40 is connected to one of the box body 10 and the door body 30, and the second torque arm 42 is supported on the other of the box body 10 and the door body 30, and when the door body 30 is in the open state, the angle between the first torque arm 41 and the second torque arm 42 is greater than the angle between the first torque arm 41 and the second torque arm 42 when the door body 30 is in the closed state. On the one hand, the torsion spring 40 can provide a torque for the door body 30 to rotate toward the box body 10 to close the dust discharge port 12. , and keeps the door body 30 in a closed state, thereby improving the reliability and effect of the door body 30 automatically closing the dust exhaust port 12. On the other hand, the second torque arm 42 is supported on the other of the box body 10 and the door body 30, which can improve the convenience and efficiency of loading and unloading the torsion spring 40 on the other of the box body 10 and the door body 30, thereby increasing the convenience and efficiency of loading and unloading between the door body 30 and the box body 10; therefore, the present application can improve the convenience and efficiency of loading and unloading the torsion spring 40 and the door body 30 of the dust collecting assembly 100.

[0040] In practical applications of the torsion spring 40, the first torque arm 41 can be connected to the box body 10, and the second torque arm 42 can be supported on the door body 30; or the first torque arm 41 can be connected to the door body 30, and the second torque arm 42 can be supported on the box body 10. The embodiment of the present application takes the example that the first torque arm 41 is connected to the door body 30 and the second torque arm 42 is supported on the box body 10.

[0041] The torsion spring 40 further includes a torsion spring body 43 connected between the first torsion arm 41 and the second torsion arm 42. The torsion spring body 43 is sleeved on the rotating shaft 20.

[0042] The outer contour of the torsion spring body 43 is cylindrical, which is formed by a metal wire spiral, and can be elastically deformed under the action of external force, and return to its original state after the external force is removed. When the torsion spring 40 is in a natural state, the torsion spring body 43 does not undergo elastic deformation, and the angle between the first torque arm 41 and the second torque arm 42 is the second angle; when the door body 30 is successfully installed on the box body 10, the angle between the first torque arm 41 and the second torque arm 42 increases from the second angle to the first angle, so that the torsion spring body 43 is twisted to provide a torque for the door body 30 to rotate toward the box body 10, so as to close the dust outlet 12 and keep the door body 30 closed.

[0043] Please also read Figure 6 to Figure 7 , Figure 6 is a cross-sectional view of another embodiment of the dust collection assembly provided by the present application; Figure 7 yes Figure 6The enlarged view of part B in FIG. When the door body 30 is opened relative to the box body 10, the angle between the first torque arm 41 and the second torque arm 42 gradually increases from the first angle, so that the twisted deformation of the torsion spring body 43 gradually increases, and the elastic restoring force stored in the torsion spring body 43 toward the box body 10 also gradually increases; when the opening angle of the door body 30 relative to the box body 10 reaches the maximum, the elastic restoring force stored in the torsion spring body 43 toward the box body 10 also reaches the maximum; when the door body 30 needs to be closed, the torsion spring body 43 can release the elastic restoring force to automatically drive the door body 30 to close, thereby realizing the automatic closing of the dust discharge port 12 by the door body 30.

When the torsion spring 40 is mounted on the door body 30, the second torque arm 42 extends in a direction away from the mounting surface 35, and an end of the second torque arm 42 close to the torsion spring body 43 is supported on the second limiting portion 32, and an end away from the torsion spring body 43 is in a suspended state, that is, an end of the second torque arm 42 having the second end 421 is in a suspended state, for being supported on the box body 10.

[0053] In some embodiments, please refer to Figure 5 The torsion spring 40 includes two first torsion arms 41 and two torsion spring bodies 43. A first torsion arm 41, a torsion spring body 43, a second torsion arm 42, another torsion spring body 43 and another first torsion arm 41 are connected in sequence.

[0054] The second torque arm 42 is connected between the two torsion spring bodies 43 , and one of the first torque arms 41 is connected to one end of the torsion spring body 43 away from the second torque arm 42 , and the other first torque arm 41 is connected to the other end of the torsion spring body 43 away from the second torque arm 42 .

[0055] The door body 30 is provided with two first limiting parts 31 and two fixing parts 36. Among them, the two first limiting parts 31 are relatively arranged on both sides of the second limiting part 32, and are spaced apart from the second limiting part 32. A limiting groove 30a is formed between the two first limiting parts 31 and the second limiting part 32. The two fixing parts 36 are relatively arranged on both sides of the second limiting part 32, and are located below the first limiting part 31. The two fixing parts 36 are spaced apart from the second limiting part 32 to form an avoidance gap 36b between the fixing part 36 and the second limiting part. The avoidance gap 36b is connected to the insertion hole 36a of the fixing part 36, and the first torque arm 41 is inserted into the insertion hole 36a of the fixing part 36 through the avoidance gap 36b.

[0056] In some embodiments, the position of the insertion hole 36a of the fixing portion 36 is lower than the position of the side of the second limiting portion 32 facing away from the first limiting portion 31, and the second limiting portion 32 will not hinder the process of inserting the first torque arm 41 into the insertion hole 36a, thereby improving the insertion efficiency of the first torque arm 41 into the insertion hole 36a, thereby improving the installation efficiency of the torsion spring 40 installed on the door body 30. After the first torque arm 41 is inserted into the insertion hole 36a, the torsion spring 40 can be turned over toward one side of the second limiting portion 32, so that the torsion spring body 43 is clamped in the limiting groove 30a, and the second torque arm is supported on the plane of the second limiting portion 32 facing the first limiting portion 31. The avoidance gap 36b is used to avoid the first torque arm 41, so that after the first torque arm 41 is inserted into the insertion hole 36a, the torsion spring 40 can be turned over, thereby further improving the installation efficiency of the torsion spring 40 installed on the door body 30.

[0057] In some embodiments, the first torque arm 41 includes a first end 411 and a first extension 412. One end of the first extension 412 is connected to one end of the torsion spring body 43 away from the second torque arm 42, and the other end is connected to the first end 411. The first end 411 is used to be inserted into the insertion hole 36a. The second torque arm 42 includes a second end 421 and two second extensions 422. Among the two second extensions 422, one of the second extensions 422 is connected between one end of the second end 421 and one torsion spring body 43, and the other second extension 422 is connected between the other end of the second end 421 and the other torsion spring body 43. When the torsion spring 40 is installed on the door body 30, one end of the second extension 422 close to the torsion spring body 43 is supported on the second limiting portion 32, and one end of the second extension 422 away from the torsion spring body 43 and the second end 421 are in a suspended state, so as to be supported on the box body 10.

[0058] When the torsion spring 40 is in a natural state, the axes of the first ends 411 of the two first torque arms 41 can be located on the same straight line, that is, the first ends 411 of the two first torque arms 41 can be coaxially arranged. The two second extensions 422 of the second torque arm 42 are arranged in parallel, the second end 421 is connected between the two second extensions 422, and the axis of the second end 421 can be parallel to the axis of the first end 411, so that after the second extension 422 is supported on the second limiting portion 32, the torsion spring 40 can maintain a horizontal state to prevent the torsion spring 40 from tilting, which is conducive to achieving the coaxial arrangement of the through hole 431 of the torsion spring body 43 and the first mounting hole 331 on the door body 30, effectively improving the convenience and efficiency of the subsequent installation of the rotating shaft 20.

[0059] Please continue reading Figure 4 and Figure 7The box body 10 is provided with a support portion 13. The second torque arm 42 abuts against the support portion 13 to further increase the torque of the torsion spring body 43, so that the torsion spring body 43 provides the door body 30 with a torque to rotate toward the box body 10 to close the dust discharge port 12.

[0060] Specifically, when the door body 30 is installed on the box body 10, the end of the second extension portion 422 away from the torsion spring body 43 and the second end portion 421 abut against the support portion 13. When the second torque arm 42 abuts against the support portion 13, the second torque arm 42 will be further lifted, so that the angle between the first torque arm 41 and the second torque arm 42 increases from the third angle when the torsion spring 40 is installed on the door body 30 to the first angle, so as to further increase the torsion of the torsion spring body 43, so that the torsion spring body 43 can provide the door body 30 with a torque to rotate toward the box body 10, so as to close the dust discharge port 12 and keep the door body 30 in a closed state. The torque provided by the torsion spring 40 to the door body 30 is related to the height of the support portion 13, and the torque provided by the torsion spring 40 to the door body 30 can be adjusted by designing the height of the support portion 13, so that the torsion spring 40 can provide the door body 30 with sufficient torque to close the dust discharge port 12.

[0061] In some embodiments, please refer to Figure 2 The support portion 13 includes a support platform 131 and a third limiting portion 132. The second torque arm 42 abuts against the support platform 131. The third limiting portion 132 is arranged relative to the end of the support platform 131 close to the rotating shaft 20. The second torque arm 42 is arranged on a side of the support platform 131 close to the third limiting portion 132 to limit the axial movement of the second torque arm 42 along the rotating shaft 20.

[0062] The support portion 13 includes two third limiting portions 132. The two third limiting portions 132 are relatively arranged on both sides of the support platform 131. By arranging the second torque arm 42 on one side of the support platform 131 close to the third limiting portions 132, the second torque arm 42 is limited between the two third limiting portions 132 on both sides along the axial direction of the rotating shaft 20, so as to avoid the second torque arm 42 from swinging left and right during the process of opening and closing the door body 30, and improve the stability of the second torque arm 42 after being supported on the support platform 131.

[0063] In some embodiments, the door body 30 is provided with a first mounting hole 331. The box body 10 is provided with a second mounting hole 14. The rotating shaft 20 passes through the second mounting hole 14, the torsion spring body 43 and the first mounting hole 331, and the first mounting hole 331, the second mounting hole 14 and the torsion spring body 43 are coaxially arranged. The rotation plane of the door body 30 is arranged parallel to the axial direction of the dust exhaust port 12.

[0064] In some embodiments, a first avoidance groove 13a is formed on one side of the third limiting portion 132 facing the door body 30, and the plane where the bottom of the first avoidance groove 13a is located can be parallel to the plane where the side of the support platform 131 close to the third limiting portion 132 is located. The first avoidance groove 13a corresponds to at least part of the second mounting hole 14 on the box body 10, and the first avoidance groove 13a corresponds to the limiting groove 30a on the door body 30. The first avoidance groove 13a is used to avoid the torsion spring body 43, so that when the second torque arm 42 abuts against the support platform 131, the first mounting hole 331 on the door body 30 can correspond to the second mounting hole 14 on the box body 10.

[0065] The door body 30 is provided with two mounting parts 33, and the two mounting parts 33 are arranged opposite to each other. One of the mounting parts 33 is located on the side of a first limiting part 31 facing away from the second limiting part 32, and the other mounting part 33 is located on the side of another first limiting part 31 facing away from the second limiting part 32. Both first mounting parts 33 are provided with a first mounting hole 331, and the two first mounting holes 331 are coaxially arranged. Two second mounting holes 14 are provided on the box body 10, and the two second mounting holes 14 are coaxially arranged, one of the second mounting holes 14 is located on the side of a third limiting part 132 facing away from the support platform 131, and the other second mounting hole 14 is located on the side of another third limiting part 132 facing away from the support platform 131. A second avoidance groove 16 is formed between the two second mounting holes 14 and the closest third limiting part 132, and the second avoidance groove 16 is connected between the first avoidance groove 13a and the second mounting hole 14. The second avoidance groove 16 is used to accommodate the mounting part 33. When the second torque arm 42 abuts against the support platform 131 , the mounting portion 33 is received in the second avoidance groove 16 , so that the first mounting hole 331 , the second mounting hole 14 and the torsion spring body 43 are coaxially arranged.

[0066] By arranging the second mounting hole 14, the first mounting hole 331 and the torsion spring body 43 coaxially, the rotating shaft 20 can pass through the second mounting hole 14, the first mounting hole 331 and the torsion spring body 43 more smoothly, thereby improving the installation operation of the rotating shaft 20 to be more convenient, labor-saving and smooth, thereby saving the installation time of the rotating shaft 20, improving the installation efficiency of the rotating shaft 20, and increasing the convenience and efficiency of the installation between the door body 30 and the box body 10.

[0067] In some embodiments, threads are provided at both ends of the rotating shaft 20. After the rotating shaft 20 is installed, the two ends of the rotating shaft 20 can pass through the second mounting hole 14 on the side facing away from the second avoidance groove 16, and the rotating shaft 20 is fixed by locking the fixing component with threads with the rotating shaft 20 to prevent the rotating shaft from falling off, wherein the fixing component can be a nut, but is not limited thereto. In other embodiments, the two ends of the rotating shaft 20 are set in a bite shape, and after the rotating shaft 20 is installed, the two ends of the rotating shaft 20 are located in the second mounting hole 14 of the box body 10, and the two ends of the rotating shaft 20 are interference fit with the inner wall of the second mounting hole 14 to fix the rotating shaft 20.

[0068] In some embodiments, the box body 10 is further formed with a dust exhaust passage 15 located outside the dust collecting chamber 11 and connected to the dust exhaust port 12. The door body 30 is rotatably connected to the side wall of the dust exhaust passage 15 through the rotating shaft 20, so that the door body 30 at least partially enters the dust exhaust passage 15 or moves out of the dust exhaust passage 15 to close or open the dust exhaust port 12.

[0069] The dust collecting chamber 11, the dust discharge port 12 and the dust discharge channel 15 are sequentially connected in the first direction XX. The dust discharge channel 15 has a first side wall 151 and a second side wall 152 arranged opposite to each other in the second direction YY. Among them, the first direction XX is perpendicular to the second direction YY. The first side wall 151 and the second side wall 152 are located on both sides of the dust discharge port 12. The second mounting hole 14 is opened on the first side wall 151 and the second side wall 152. The second mounting hole 14 is provided on at least one of the first side wall 151 and the second side wall 152. When the first side wall 151 and the second side wall 152 are both provided with the second mounting hole 14, the second mounting hole 14 on the first side wall 151 and the second mounting hole 14 on the second side wall 152 are coaxially arranged in the second direction YY, so as to facilitate the alignment of the first mounting hole 331 on the door body 30 with the second mounting hole 14, which can effectively improve the convenience and efficiency of the installation of the rotating shaft 20.

[0070] The side of the door body 30 close to the box body 10 can enter the dust exhaust passage 15, so that the side of the door body 30 facing the box body 10 is closely fitted with the periphery of the dust exhaust port 12 to close the dust exhaust port 12 and improve the sealing effect between the door body 30 and the periphery of the dust exhaust port 12. The end of the door body 30 away from the rotating shaft 20 can be moved out of the dust exhaust passage 15 to open the dust exhaust port 12.

[0071] In some embodiments, the dust collecting assembly 100 further includes a sealing member 34. The sealing member 34 is disposed on a side of the door body 30 facing the dust collecting chamber 11, and is used to seal the dust discharge port 12 when the door body 30 closes the dust discharge port 12.

[0072] The seal 34 is used to seal the dust outlet 12 when the door body 30 closes the dust outlet 12. Specifically, when the seal 34 seals the dust outlet 12, the sealing skirt of the seal 34 and the periphery of the dust outlet 12 are sealed by interference fit to ensure that when the dust collecting assembly 100 is in the dust collecting state, the dust outlet 12 will not leak and affect the dust collecting effect of the dust collecting assembly 100. When the dust, dandruff, hair and other objects in the dust collecting assembly 100 need to be discharged, the cleaning device can be placed on the base station, and the base station can give a certain pulling force to the door body 30 to drive the door body 30 to open, or the user can manually give a certain pulling force to the door body 30 to open the door body 30, so that the base station can easily suck out the objects in the dust collecting chamber 11; or the user can also manually pour out the objects in the dust collecting chamber 11. When the door body 30 needs to be closed, the pulling force applied to the door body 30 by the base station or the user is canceled, so that the torsion spring 40 can release the stored elastic restoring force to automatically drive the door body 30 to close, thereby realizing the automatic closing of the dust outlet 12 by the door body 30.

[0073] The setting of the seal 34 can seal the door body 30 and the periphery of the dust discharge port 12 when the dust collecting assembly 100 is in the dust collection state. The sealing reliability between the door body 30 and the periphery of the dust discharge port 12 is strong. On the one hand, it can prevent the negative pressure environment in the dust collecting chamber 11 from being affected by air leakage from the dust discharge port 12 during the dust collection process. On the other hand, it can prevent the objects in the dust collecting chamber 11 from leaking out of the dust discharge port 12 when there is no need to discharge the objects in the dust collecting chamber 11 through the dust discharge port 12, thereby greatly improving the user experience.

[0074] The material of the sealing member 34 can be selected from rubber, silicone, sponge or wool felt, but is not limited thereto. Rubber, silicone, sponge and wool felt all have good elasticity, so that the sealing member 34 has elasticity, so that the door body 30 and the periphery of the dust discharge port 12 can be better sealed, thereby improving the sealing effect of the door body 30 on the dust discharge port 12.

[0075] In some embodiments, please refer to Figures 2 to 3, the box body 10 is provided with a first clamping portion 17, and the door body 30 is provided with a second clamping portion 37 matched with the first clamping portion 17. The first clamping portion 17 on the box body 10 can be arranged on the side of the dust discharge port 12 away from the rotation shaft 20, and the second clamping portion 37 is arranged on the side of the door body 30 facing the box body 10, and is located on the side of the door body 30 away from the rotation shaft 20; or the first clamping portion 17 can be arranged on the first side wall 151 and / or the second side wall 152 of the dust discharge channel 15, and the second clamping portion 37 is arranged at the end of the door body 30 facing the first side wall 151 and / or the second side wall 152. The first clamping portion 17 and the second clamping portion 37 are used to clamp each other when the door body 30 closes the dust discharge port 12, so as to lock the door body 30 and the box body 10, so that the door body 30 cannot automatically overcome the torque of the torsion spring 40 toward the box body 10 and rotate in the direction away from the dust discharge port 12, thereby improving the reliability of the door body 30 closing the dust discharge port 12. When the door body 30 needs to be opened, the door body 30 is pulled in the direction away from the dust discharge port 12 to release the clamping of the first clamping portion 17 and the second clamping portion 37. One of the first clamping portion 17 and the second clamping portion 37 can be a clamping groove, and the other of the first clamping portion 17 and the second clamping portion 37 can be a buckle.

[0076] In some embodiments, a suction cup is provided on one of the box body 10 and the door body 30, and the adsorption surface of the suction cup is used to face the other of the box body 10 and the door body 30, and the door body 30 and the box body 10 are locked by adsorption of the suction cup; or a first magnetic component is provided on one of the box body 10 and the door body 30, and a second magnetic component is provided on the other of the box body 10 and the door body 30, and the door body 30 and the box body 10 are locked by magnetic attraction.
