[0072] This application aims to provide a cleaning device for cleaning a surface to be cleaned. The cleaning device is capable of generating negative pressure to force dust and debris on the surface to be cleaned into the interior of the cleaning device. For example, the cleaning device may be a vacuum cleaner.

[0073] For example, the surface to be cleaned can be a floor or a carpet.

[0074] For example, please refer to Figure 1 The cleaning equipment mainly includes the following working components: air duct assembly 100, dust cup device 200, fan assembly 300, cover plate device 400, handle 500 and power supply assembly 600.

[0075] The functions of the main working components of the cleaning equipment are as follows:

[0076] For example, please refer to Figure 3 The air duct assembly 100 includes an air duct 110, which forms an air intake passage 110a. The air duct assembly 100 is used to guide airflow so that air carrying dust and debris enters the air intake passage 110a and then passes through the dust cup device 200 in the air intake passage 110a.

[0077] For example, the dust cup device 200 is capable of cyclone separation of dust and air to separate dust and debris from the airflow, and the separated airflow flows to the fan assembly 300.

[0078] It should be noted that in some embodiments, please refer to [the relevant documentation / reference]. Figures 1 to 3The central axis of the dust cup device 200 is offset from the central axis of the air duct assembly 100. This design maximizes the size of the dust cup device 200 along its central axis while maintaining a fixed overall length of the cleaning equipment. The dust cup device 200 can hold a larger amount of dust and debris, alleviating the need for frequent disassembly for dust removal. This design also facilitates easy disassembly and installation of the dust cup device 200. It is understood that the embodiments of this application are not limited to the central axis of the dust cup device 200 being offset from the central axis of the air duct assembly 100. In some embodiments, the central axis of the dust cup device 200 and the central axis of the air duct assembly 100 may coincide.

[0079] For example, the fan assembly 300 can generate negative pressure to allow external airflow to enter the air duct assembly 100. The separated airflow will pass through the fan assembly 300 and then flow to the outside through the air outlet of the fan assembly 300.

[0080] For example, please refer to Figure 1 The cover plate device 400 is located on the rear side of the fan assembly 300.

[0081] For example, the fan assembly 300 is provided with a handle 500 on its lower side. The handle 500 is a part for the user to hold. The user can move the cleaning equipment by holding the handle 500, thereby cleaning the surface to be cleaned.

[0082] For example, the lower side of the handle 500 also has a power supply component 600 to provide power to the fan assembly 300, etc.

[0083] The following section will introduce each working component according to the airflow direction in the cleaning equipment.

[0084] First, please refer to Figure 3 It illustrates an air duct assembly 100, the central axis of which is offset from the central axis of the dust cup device 200. See further details. Figures 3 to 11 The air duct assembly 100 includes an air duct 110, which includes a first duct body 111 and a second duct body 112. One end of the second duct body 112 is connected to one end of the first duct body 111, thereby achieving airflow reversal. For details, please refer to... Figure 3The sucked-in dust first flows along the first direction R1, and when it reaches the rightmost end of the air duct 110, it turns and flows along the second direction R2, for example, turning 80° or 90°, etc., which is not limited here. In this embodiment, by designing the air duct 110 as a split structure, the first tube 111 and the second tube 112 can be manufactured independently in the mold, which reduces the difficulty of demolding the air duct 110. Compared with making the air duct into a one-piece structure, the inner tube wall formed by the overall demolding makes the inner tube walls of the first tube 111 and the second tube 112 smoother, improves the smoothness of airflow, and makes the cleaning effect of the cleaning equipment better.

[0085] It should be noted that the front end of the air duct 110 can be connected to one or more plug pipes, and the front end of the plug pipe can be further connected to the ground brush, etc., to adapt to different application scenarios.

[0086] In some embodiments, please refer to Figure 3 Since the first tube 111 and the second tube 112 need to achieve airflow reversal, in order to ensure smooth flow of dust and reduce the blockage of impurities, the internal channel is set with an arc transition.

[0087] Specifically, in some embodiments, please refer to Figure 3 and Figure 8 At the connection between the first tube 111 and the second tube 112, at least part of the inner wall of the first tube 111 facing the second tube 112 is provided as an arc-shaped surface. It should be noted that this arc-shaped surface is located behind the central axis of the second tube 112.

[0088] In other embodiments, please refer to Figure 3 and Figure 10 At the connection between the first tube 111 and the second tube 112, at least part of the inner wall of the second tube 112 facing the first tube 111 is provided as an arc-shaped surface. It should be noted that this arc-shaped surface is located in front of the central axis of the second tube 112.

[0089] It is understandable that an arc can be a segment of a circle, or it can be an arc of multiple circles, or a nearly smooth transition line or other smooth curve formed by connecting multiple lines.

[0090] In some embodiments, please refer to Figure 3The connection between the first tube 111 and the second tube 112 is configured as an arc-shaped structure 113. The arc-shaped structure 113 includes a first curved surface 113a and a second curved surface 113b, which are located on opposite sides of the arc-shaped structure 113. It can be understood that the first curved surface 113a refers to the portion connected to the first tube 111 and curved towards the second tube 112; the second curved surface 113b refers to the portion connected to the second tube 112 and curved towards the first tube 111.

[0091] For example, the first curved surface 113a is integrally formed with the first tube body 111.

[0092] For example, the second curved surface 113b is integrally formed with the second tube body 112.

[0093] In some embodiments, please refer to Figure 3 and Figure 7 The first tube body 111 includes a straight tube section 111f, the length of which is greater than the arc length of the first curved section 113a. This allows the vacuum cleaner to reach a more distant location, thereby increasing the cleaning range and reducing the need for users to bend over significantly while using the vacuum cleaner. The straight tube section 111f refers to the portion of the first tube body 111 that extends along the first direction R1.

[0094] It is understood that the embodiments of this application do not limit the length of the straight pipe segment 111f to be greater than the arc length of the first curved surface 113a. Exemplarily, the length of the straight pipe segment 111f is less than or equal to the arc length of the first curved surface 113a.

[0095] In some embodiments, please refer to Figure 3 and Figure 4 The first curved surface 113a includes a first end face 111a, and the second curved surface 113b includes a second end face 112a. The first end face 111a and the second end face 112a are fitted together.

[0096] In the embodiment of this application, the air duct 110 has good sealing performance due to the mutual contact between the first end face 111a and the second end face 112a, which alleviates the situation of airflow moving through the gap between the first pipe body 111 and the second pipe body 112.

[0097] In some embodiments, please refer to Figure 7 The first end face 111a includes a first region face 111b and a second region face 111c connected together, and the included angle formed by the intersection of the first region face 111b and the second region face 111c is an obtuse angle.

[0098] It should be noted that the first region surface 111b and the second region surface 111c can be a plane or an arc surface. When the first region surface 111b and / or the second region surface 111c is an arc surface, the angle formed by the first region surface 111b and the second region surface 111c toward the second end surface 112a is the angle formed by the tangent of the arc surface at the intersection of the first region surface 111b and the second region surface 111c.

[0099] In the embodiments of this application, by setting the included angle between the first region surface 111b and the second region surface 111c to an obtuse angle, it is convenient for the first end surface 111a and the second end surface 112a to fit together. Furthermore, the obtuse angle can reduce the processing requirements of the mold, simplify demolding, and reduce stress concentration.

[0100] It is understood that the embodiments of this application do not limit the angle between the first region surface 111b and the second region surface 111c to an obtuse angle. Exemplarily, the angle between the first region surface 111b and the second region surface 111c can be a right angle or an acute angle.

[0101] In some embodiments, please refer to Figure 6 and Figure 8 A sealing element (not shown in the figure) is provided between the second tube body 112 and the first tube body 111. The first tube body 111 is provided with a sealing groove 111d to accommodate the sealing element. Specifically, the sealing groove 111d is provided on the first end face 111a.

[0102] For example, the seal is an O-ring.

[0103] For example, the seal is made of silicone or rubber.

[0104] In the solution of this application embodiment, by adding a sealing element between the second pipe body 112 and the first pipe body 111, the sealing element can further increase the sealing between the first pipe body 111 and the second pipe body 112, preventing dust from leaking out between the first pipe body 111 and the second pipe body 112 during the operation of the cleaning equipment, and at the same time making the air duct assembly 100 more stable and reliable during use.

[0105] It is understood that the embodiments of this application do not limit whether a seal is provided between the second tube 112 and the first tube 111.

[0106] In some embodiments, please refer to Figure 5 and Figure 6 The first tube body 111 and the tube body 112 are connected by a boss 111e, and a sealing groove 111d is provided on the boss 111e. The second tube body 112 is provided with a connecting part 112b, which can be adapted to connect to the boss 111e.

[0107] It is understandable that the connecting part 112b is provided on the second end face 112a.

[0108] In the embodiments of this application, by providing the sealing groove 111d on the boss 111e, the strength of the first pipe body 111 can be guaranteed even with the sealing groove 111d provided. Furthermore, the boss 111e also improves the connection reliability between the first pipe body 111 and the second pipe body 112.

[0109] It is understood that the embodiments of this application do not limit whether the outer wall of the first tube 111 is provided with a boss 111e.

[0110] In some embodiments, please refer to Figure 5 The connecting part 112b includes a protrusion 112c, which is used to cooperate with the sealing groove 111d to press the seal, thereby reducing the gap between the first tube body 111 and the sealing element, and further improving the sealing performance.

[0111] It is understood that the embodiments of this application do not limit whether the connecting part 112b is provided with a protrusion 112c.

[0112] In some embodiments, the first tube 111 and the second tube 112 can be fastened together by a snap-fit ​​structure. One or more snap-fit ​​structures can be provided.

[0113] In some embodiments, please refer to Figures 6 to 11 The first tube body 111 is provided with a first locking protrusion 1110, wherein the first locking protrusion 1110 is located on one side of the first tube body 111 along the first direction R1, and the first locking protrusion 1110 protrudes from the first tube body 111 along the first direction R1 (specifically, rearward). For example, there are two first locking protrusions 1110, respectively along the two sides of the third direction R3. It is understood that there can be three or more first locking protrusions 1110. The second tube body 112 is provided with a first snap-fit ​​member 1121, which has a snap-fit ​​hole 1121a. The snap-fit ​​hole 1121a is used to engage with the first locking protrusion 1110, so that the inner walls of the snap-fit ​​hole 1121a limit the first locking protrusion 1110. It is understood that the number of first snap-fit ​​members 1121 is the same as the number of first locking protrusions 1110.

[0114] In some embodiments, please refer to Figures 6 to 11The first tube body 111 is also provided with a second locking protrusion 1111, which is located on the other side (specifically, the front) of the first tube body 111 along the first direction R1, and protrudes from the first tube body 111 in a direction perpendicular to the first direction R1. For example, there are two second locking protrusions 1111, one on each side along the third direction R3. It is understood that there can be three or more second locking protrusions 1111. The second tube body 112 is provided with a second snap-fit ​​member 1120, which has a hook 1120a that abuts against the lower end face of the first locking protrusion 1110. It is understood that the number of second snap-fit ​​members 1120 is the same as the number of second locking protrusions 1111.

[0115] During installation, the locking hole 1121a is fitted onto the first locking protrusion 1110, and then the second tube 112 is rotated until the locking hook 1120a is engaged with the second locking protrusion 1111, thus completing the assembly of the first tube 111 and the second tube 112, and enabling mutual positioning of the first tube 111 and the second tube 112 in multiple directions.

[0116] It is understood that the embodiments of this application do not limit the assembly method between the first tube 111 and the second tube 112. Exemplarily, the first tube 111 and the second tube 112 can also be fixedly connected by screws or pins.

[0117] In some embodiments, please refer to Figure 3 The cleaning equipment also includes a sensor 700, which is installed on the inner wall of the air duct 110. The sensor 700 is used to detect the amount of dust carried by the airflow in the air duct 110, thereby adjusting the power of the fan assembly 300. The greater the amount of dust, the greater the power of the fan assembly 300 is controlled.

[0118] Understandably, the cleaning equipment also includes a ribbon cable (not shown in the diagram) for connecting components such as the sensor 700. Please refer to [link / reference]. Figure 8 and Figure 9 The first tube 111 is provided with a wire buckle 111g, which is used to fix the wiring so that the wiring is arranged in a predetermined direction. The second tube 112 is provided with an avoidance notch 112d, which is used to avoid the wire buckle 111g and the wiring.

[0119] In some embodiments, please refer to Figure 2 and Figure 3 The dust cup device 200 is connected and installed on the air duct assembly 100. The dust cup device 200 includes dust cups 210 connected to each other, and the dust cups 210 have dust collection chambers 210a.

[0120] Please refer to further information. Figure 3 and Figure 6 The second tube 112 includes a third end face 112e, which is used to connect the second tube 112 to the air inlet 200a of the dust cup device 200, so as to realize the connection between the dust collection chamber 210a and the air inlet channel 110a, and guide the dust gas from the first tube 111 to the dust cup device 200.

[0121] In some embodiments, in order to form an air intake channel 110a, the second pipe body 112 is provided with a guide portion 112f, which is located between the second end face 112a and the third end face 112e, and the air intake channel 110a is located inside the guide portion 112f.

[0122] Please see Figure 11 On the projection plane perpendicular to the first direction R1, the axial direction of the guide part 112f has an angle α with the second direction R2, satisfying 0°≤α≤90°. For example, α can be an angle such as 0°, 30°, 45°, 60° or 90°.

[0123] In some embodiments, on a projection plane perpendicular to the first direction R1, the projection of the central axis of the second tube 112 forms an angle α with the second direction R2, satisfying 0° < α < 90°. For example, α can be an angle such as 10°, 30°, 45°, 60°, or 80°. This arrangement allows the dust and air entering the dust cup 210 from the air guide duct 110 to easily form a spiral airflow, which is beneficial for the cyclone separation of dust and air.

[0124] It is understood that in some embodiments, the included angle α satisfies the condition that the dust gas enters the dust cup 210 along the tangential direction of the inner wall of the dust cup 210, and the dust gas can flow circumferentially along the inner wall of the dust cup 210, which is more conducive to forming a spiral airflow.

[0125] In some embodiments, in order to connect and fix the dust cup device 200 and the air duct assembly 100, the air duct assembly 100 includes a first connector 120, and the dust cup device 200 includes a second connector 220 disposed on the outer side wall of the dust cup 210. When the second connector 220 is installed on the first connector 120, the air inlet 200a is connected to the air inlet channel 110a.

[0126] In some embodiments, please refer to Figure 3 and Figure 12 The first connector 120 is configured as a connecting groove, and the second connector 220 is configured as a hook. The second connector 220 can extend into the connecting groove from the opening of the connecting groove so that the hook and the connecting groove can be engaged with each other, thereby avoiding jamming during the installation of the dust cup device 200 and improving the efficiency of disassembly and assembly.

[0127] It should be noted that the first connector 120 includes a top wall and a side wall, which together form a connecting groove, the opening of which faces the dust cup device 200 along the first direction R1.

[0128] In some embodiments, the outer edge of the top wall is chamfered to facilitate the insertion of the hook.

[0129] In some embodiments, the air duct 110 and the first connector 120 are integrally formed. Furthermore, the sidewalls are inclined straight surfaces, which facilitates integral forming.

[0130] Understandably, please refer to Figure 2 The air duct assembly 100 also includes a pipe shell 130 disposed on the outside of the air duct 110. The pipe shell 130 is fixed to the air duct 110 by means of snap-fit ​​or threaded connection. The first connector 120 is formed by a portion of the pipe shell 130.

[0131] Specifically, a notch is formed in the upper region of a portion of the casing 130, and the top wall is formed by a portion of the casing wall located around the notch. When the hook is engaged in the connecting groove, some or all of the hook is located in the notch. This design allows the upper casing 130 to support the dust cup device 200, while the peripheral wall of the notch provides a limiting effect on the second connector 220, improving the stability of the dust cup device 200 installation. In addition, this design also facilitates the manufacturing of the first connector 120.

[0132] For example, the second connector 220 is integrally formed with the dust cup 210.

[0133] It should be noted that the cable clip 111g and the cable itself are located in the gap space between the housing 130 and the first tube 111.

[0134] In some embodiments, the dust entering the dust cup device 200 through the air inlet 200a is further separated by a cyclone separator 240. For details, please refer to [link to relevant documentation]. Figure 14 and Figure 15 The dust cup 210 has an air outlet 210b at one end and an openable and closable cover 230 at the other end. The separation component 240 is located inside the dust cup 210.

[0135] In some embodiments, please refer to Figures 13 to 17 The separation component 240 includes a first separator 241 and a second separator 242. The first separator 241 is cylindrical and has a filter screen 250 on it for primary separation of dust and gas fed into the dust cup device 200 by the second tube 112. The second separator 242 is located inside the cylindrical first separator 241 and is used for secondary separation of dust and gas after separation by the first separator 241.

[0136] It is understandable that the entire filter cylinder 250 can be made into a filter, or that filter screens can be spaced out on the filter cylinder 250.

[0137] It is also understandable that the filter cartridge 250 can be made of either metal or plastic.

[0138] In some embodiments, please refer to Figure 14 and Figure 15 The first dust collection chamber 210c is formed between the cylindrical first separator 241 and the inner wall of the dust cup 210. It is understood that the first dust collection chamber 210c is connected to the interior of the first separator 241 only through a hole in the filter cylinder 250. Dust entering the dust cup 210 forms a spiral airflow along the inner wall of the first dust collection chamber 210c. Some impurities remain in the first dust collection chamber 210c, while the filtered airflow passes through the filter cylinder 250 and enters the interior of the first separator 241.

[0139] Understandably, the rear side of the first separator 241 is connected to the dust cup 210, and the front side of the first separator 241 is connected to the cylinder cover 230.

[0140] In some embodiments, please refer to Figure 15 The first separator 241 has a partition 243 at its rear end, and the partition 243 has at least one third through hole 243a communicating with the air outlet 210b. A second separator 242 is installed on the front side of the partition 243. The second separator 242 has at least one separation unit 242a. The internal channel formed by the separation unit 242a is connected to the third through hole 243a, so that the airflow separated by the second separator 242 flows to the air outlet 210b through the third through hole 243a.

[0141] It is understood that the embodiments of this application do not limit the number of separation units 242a. Exemplarily, the number of separation units 242a is single (e.g., Figure 30 (As shown), it can also be two, three or more (as shown) Figure 16 , Figure 32 (As shown).

[0142] In some embodiments, please refer to Figure 15 Each separation unit 242a includes an inner tube 2420 and an outer tube 2421. The inner tube 2420 is directly connected to the third through hole 243a. The outer tube 2421 is spaced apart from the cylinder wall of the first separator 241 to form a space 242e. At least part of the inner tube 2420 extends into the outer tube 2421. An air inlet gap 242d is formed at the end of the outer tube 2421 near the partition 243. After primary separation, the air flows through the filter cylinder 250 into the space 242e and enters the separation unit 242a through the air inlet gap 242d for secondary separation.

[0143] It is understandable that the space 242e and the first dust collection chamber 210c are connected only by the hole on the filter cylinder 250. Specifically, the inner wall of the end of the filter cylinder 250 facing the cylinder cover 230 and the outer wall of the outer tube 2421 can be sealed with a sealing plate.

[0144] In some embodiments, please refer to Figure 14 and Figure 15 The portion inside the first separator 241 and located in front of the second separator 242 constitutes the second dust collection chamber 242c, which is connected to both the outer pipe 2421 and the inner pipe 2420.

[0145] Understandably, please refer to Figure 15 , Figure 30 and Figure 32 The inner tube 2420 and the outer tube 2421 are spaced apart to form a channel 242b. The airflow enters the channel 242b through the air intake gap 242d for secondary separation.

[0146] It is understood that, in some embodiments, please refer to Figure 30 and Figure 32 The inner tube 2420 can be integrated with the partition 243 as a single structural component. For example, the inner tube 2420 can be formed by stamping the partition 243. In other embodiments, the inner tube 2420 and the partition 243 are processed separately, and the inner tube 2420 is connected to the partition 243 by welding, threaded connection or other means.

[0147] It should be noted that in some embodiments, please refer to [the relevant documentation / reference]. Figures 15 to 17 , Figure 30 and Figure 32 The overall length of the outer tube 2421 is greater than the length of the inner tube 2420 extending into the outer tube 2421, so as to better improve the dust and gas separation effect.

[0148] It is also understood that, in some embodiments, please refer to Figure 15 The outer tube 2421 is spaced apart from the partition 243 at one end along its axial direction near the partition 243, thereby forming an intake gap 242d.

[0149] In some embodiments, please refer to Figure 30 and Figure 32 The outer pipe 2421 is connected to the partition plate 243. An opening extending along the axis of the outer pipe 2421 is formed on the pipe wall near the partition plate 243. This opening forms the air intake gap 242d. It can be understood that the length of the air intake gap 242d extending along the axis of the outer pipe 2421 can be reasonably selected according to the volume of the first separator 241.

[0150] In some embodiments, please refer to Figure 14 and Figure 15 The separation unit 242a also includes a dust outlet section 244, which is connected to the end of the outer tube 2421 away from the inner tube 2420. The inner diameter of the dust outlet section 244 gradually decreases in the direction away from the outer tube 2421.

[0151] In the embodiment of this application, the dust outlet 244 is generally conical in shape, which can accelerate the rotation of the airflow, thereby making the dust fall off more efficiently.

[0152] It is understood that the embodiments of this application do not limit the shape of the dust outlet 244. For example, the dust outlet 244 is generally conical in shape.

[0153] In some embodiments, please refer to Figure 30 The dust outlet end of the dust outlet section 244 is provided with a baffle 244a, and a dust outlet 244c is formed between the baffle 244a and the peripheral wall of the dust outlet section 244, so that dust is discharged radially along the dust outlet section 244 and falls into the second dust collection chamber 242c. This configuration can improve the efficiency of dust-air separation and avoid the dust-air separation effect being unsatisfactory when the dust outlet port of the dust outlet section 244 is large. For example, when only a small number of separation units 242a are provided (e.g., 1, 2, etc.).

[0154] In some embodiments, please refer to Figure 30 The baffle 244a is connected to the peripheral wall of the dust outlet 244 by two or more connecting ribs 244b, and a dust outlet 244c is formed between adjacent connecting ribs 244b.

[0155] To create a cyclone within the separation unit 242, the following approach can be adopted.

[0156] In some embodiments, for the configuration where the outer tube 2421 and the partition plate 243 are spaced apart to form an intake gap 242d, please refer to [reference needed]. Figure 15 The channel 242b is provided with a guide structure 2422 for guiding the airflow so that the airflow in the channel 242b forms a cyclone and improves the separation effect.

[0157] For details, please refer to Figure 3 , Figure 15 and Figure 17The flow guiding structure 2422 is a guide plate connected between the inner tube 2420 and the outer tube 2421. The guide plate extends along the axial direction of the outer tube 2421 and is spirally arranged around the inner tube 2420. The flow guiding structure 2422 can guide the airflow to flow circumferentially in the channel 242b, causing the airflow to rotate in the channel 242b. Dust and impurities mixed in the airflow are separated from the airflow under the action of centrifugal force and settle into the second dust collection chamber 242c. The separated air flows along the inner tube 2420 to the air outlet 210b under the action of negative pressure.

[0158] In other embodiments, please refer to Figure 16 The flow guiding structure 2422 includes three guide vanes arranged circumferentially along the outer tube 2421 and spirally surrounding the inner tube 2420. Adjacent guide vanes are spaced apart; for example, the guide vanes can be evenly distributed circumferentially along the outer tube 2421. Each guide vane guides the airflow circumferentially along the channel 242b, causing the airflow entering the outer tube 2421 to generate an air vortex within it, thereby separating dust carried in the airflow.

[0159] It should be noted that the number of guide plates in the embodiments of this application is not limited to one or three, but may be two, four or more, and can be selected according to the actual application requirements.

[0160] In some embodiments, please refer to Figure 17 Along the axial direction of the inner tube 2420, the end of the guide plate away from the intake gap 242d is set as a straight section, which is parallel to the cross-section of the inner tube 2420.

[0161] The upper end of the channel 242b is the inlet. Along the air intake direction of the channel 242b, the end of the guide plate is formed into a straight section, so that when the airflow is discharged along the guide plate, it can flow around the circumference of the channel 242b, making it easier for the airflow to form a cyclone in the inner cavity of the outer tube 2421, and the cyclone effect is better.

[0162] It is understood that the embodiments of this application do not limit the shape of the guide plate. Exemplarily, the guide plate is a straight plate.

[0163] In some embodiments, the guide plate is integrally formed with the inner tube 2420 and the outer tube 2421.

[0164] In the embodiment of this application, the guide plate is integrally formed with the inner tube 2420 and the outer tube 2421, which makes the overall strength of the separation unit 242a high.

[0165] It is understood that the embodiments of this application are not limited to the guide plate being integrally formed with the inner tube 2420 and the outer tube 2421. Exemplarily, the guide plate, the inner tube 2420 and the outer tube 2421 can be manufactured separately and then assembled together.

[0166] In some embodiments, for the scheme of forming an intake gap 242d by opening the pipe wall 2421 of the outer pipe 2421, please refer to [reference needed]. Figure 30 and Figure 32 The end of the outer pipe 2421 closest to the partition 243 is the first pipe section.

[0167] In some embodiments, please refer to Figure 32 The first pipe section includes at least one second pipe wall 2421c. Along the circumference of the outer pipe 2421, the distance from one end of the second pipe wall 2421c to the axis of the outer pipe 2421 is less than the distance from the other end of the second pipe wall 2421c to the axis of the outer pipe 2421, so as to form the air intake gap 242d at one end and / or the other end of the second pipe wall 2421c. The above arrangement enables the airflow to form a cyclone along the circumference of the second pipe wall 2421c.

[0168] For details, please refer to Figure 32 The first pipe section includes multiple second pipe walls 2421c, which are distributed circumferentially along the outer pipe 2421. An air intake gap 242d is formed between the two ends of adjacent second pipe walls 2421c. This configuration can improve airflow efficiency.

[0169] In some embodiments, please refer to Figure 30 The first pipe section includes a first pipe wall 2421b and a second pipe wall 2421c. One circumferential end of the first pipe wall 2421b and one circumferential end of the second pipe wall 2421c are connected. The other circumferential ends of the first pipe wall 2421b and the other circumferential ends of the second pipe wall 2421c form an air intake gap 242d. Extending circumferentially from the end where the second pipe wall 2421c connects to the first pipe wall 2421b to the free end of the second pipe wall 2421c, the distance between the second pipe wall 2421c and the axis of the outer pipe 2421 gradually increases. This arrangement allows the airflow to form a cyclone along the circumference of the second pipe wall 2421c and the first pipe wall 2421b.

[0170] In some embodiments, see Figures 30 to 32 The connection between the first pipe wall 2421b and the second pipe wall 2421c is smooth.

[0171] In some embodiments, see Figures 30 to 32The diameter of the circle containing the cross-section of the first pipe wall 2421b is smaller than the diameter of the circle containing the cross-section of the second pipe wall 2421c, and the connection between the first pipe wall 2421b and the second pipe wall 2421c is tangential.

[0172] In some embodiments, see Figures 30 to 32 The second pipe wall 2421c and the first pipe wall 2421b are connected by an end plate 2421a at the end of the outer pipe 2421 away from the partition 243 along the axial direction of the outer pipe 2421.

[0173] Understandably, see Figure 30 Multiple first pipe walls 2421b and multiple second pipe walls 2421c are formed along the circumference of the outer pipe 2421. For example, when only a small number of separation units 242a are set (e.g., 1, 2, etc.), multiple air inlet gaps 242d can be formed to improve the dust-gas separation efficiency.

[0174] It is understandable that the entire outer pipe 2421 can be set as the first pipe section, in which case an intake gap 242d is formed on the outer pipe 2421 that runs through its axial direction.

[0175] In some embodiments, please refer to Figure 30 The filter cylinder 250 of the first separator 241 is connected to a second cylinder 270 at the end facing the cylinder cover 230. The second cylinder 270 is sealed to the cylinder cover 230, and the average inner diameter of the filter cylinder 250 is larger than the average inner diameter of the second cylinder 270. This arrangement can increase the overall volume of the first dust collection chamber 210c.

[0176] It is understood that the filter cylinder 250 and the first cylinder 260 are connected by a transition section 280 to achieve a variable inner diameter transition. The transition section 280 can be configured as a straight conical cylinder or an arc conical cylinder to improve the smoothness of airflow. In some embodiments, the transition section 280 is configured as an annular plate 280a, such as... Figure 30 As shown, this annular plate 280a can simultaneously seal the end of the filter cylinder 250 facing the cylinder cover 230 and the outer tube 2421 to form a sealing plate.

[0177] It is understood that, in some embodiments, please refer to Figure 14 and Figure 15 The filter screen 250 of the first separator 241 is connected to the first cylinder 260 at the end facing the cylinder cover 230, and the end of the first cylinder 260 facing the cylinder cover 230 is connected to the second cylinder 270, and the second cylinder 270 is connected to the cylinder cover 230.

[0178] Understandably, at this time, the second cylinder 270 is provided with a transition section 280 connected to the first cylinder 260 to achieve a variable inner diameter transition. The transition section 280 can be set as an annular plate 280a, a straight conical cylinder, or an arc conical cylinder.

[0179] In some embodiments, please refer to Figure 14 and Figure 15 The transition section 280 is provided with a 260a at the end away from the cylinder cover 230, and the baffle 260a is spaced apart from the second cylinder 270. When the cleaning equipment is in operation, the baffle 260a can suppress the dust in the first dust collection chamber 210c. When the airflow picks up the dust and debris in the first dust collection chamber 210c, some of the dust will be blocked by the baffle 260a, thereby reducing the dust rewind.

[0180] It is understandable that the baffle 260a may not have a vent hole or may have multiple vent holes. When multiple vent holes are provided, it is beneficial for the dust and air swirled in the first dust collection chamber 210c to pass through the vent holes when the cleaning equipment reaches the baffle 260a, thereby reducing the turbulence caused by the obstruction of the baffle 260a.

[0181] In some embodiments, the inner diameter of the baffle 260a is larger than the inner diameter of the filter cylinder 250, which can improve the dust blocking ability and further reduce dust rewinding.

[0182] In other embodiments, please refer to Figure 14 and Figure 15 The filter cylinder 250, the first cylinder 260 (understandably, in some embodiments the first cylinder 260 may not be provided) and the baffle 260a have their inner diameters gradually decreasing along the axial direction near the cylinder cover, thereby increasing the volume of the first dust collection chamber 210c. In addition, due to the rotating airflow generated in the dust cup 210, the cross-sectional area of ​​the first dust collection chamber 210c gradually increases along the axial direction near the cylinder cover through the above arrangement, which makes the airflow intensity gradually weaken, making it easier for dust to be deposited in the first dust collection chamber 210c near the cylinder cover 230. At the same time, due to the weaker airflow intensity, the amount of dust raised is reduced.

[0183] In some embodiments, please refer to Figure 14 and Figure 15 The dust cup device 200 has a negative pressure chamber 200b on the rear side of the partition 243. The airflow that has undergone two-stage dust-air separation enters the negative pressure chamber 200b through the third through hole 243a, and under the action of negative pressure, it flows further toward the fan assembly 300. A low-pressure buffer zone is easily formed in the negative pressure chamber 200, which improves the dust collection efficiency.

[0184] It is understood that, in some embodiments, please refer to Figure 30The peripheral wall, partition 243 and inner tube 2420 of the negative pressure chamber 200b are set as an integral structural component. For example, the peripheral wall, partition 243 and inner tube 2420 of the negative pressure chamber 200b are formed by integral casting or integral stamping.

[0185] In some embodiments, please refer to Figure 14 and Figure 15 A motor pre-filter 291 is provided in the negative pressure chamber 200b and at the air outlet 210b to further filter the airflow and reduce the dust content of the airflow entering the fan assembly 300.

[0186] Understandably, a sealing ring can be provided around the pre-filter 291 of the motor to improve sealing and enhance negative pressure efficiency.

[0187] It is also understood that the motor pre-filter 291 can be made of materials such as filter cotton or filter; in some embodiments, the motor pre-filter 291 can fill the negative pressure chamber 200b.

[0188] In some embodiments, please refer to Figures 18 to 20 The rear end of the dust cup device 200 is detachably connected to the fan assembly 300. Specifically, the dust cup device 200 includes a third connector 290 connected to the dust cup 210, and the fan assembly 300 is provided with a fourth connector 330. The third connector 290 and the fourth connector 330 cooperate to realize the detachable installation of the dust cup device 200 and the fan assembly 300.

[0189] In some embodiments, please refer to Figure 3 The third connector 290 is located at the top rear end of the dust cup 210, and the fourth connector 330 is located at the top front end of the fan assembly 300. This arrangement facilitates the user's disassembly and assembly of the dust cup device 200.

[0190] It is understandable that the third connector 290 and the dust cup 210 can be designed as a single piece.

[0191] In the embodiment of this application, the dust cup device 200 is connected and assembled with the air duct assembly 100 through the first connector 120 and the second connector 220, and connected and assembled with the fan assembly 300 through the third connector 290 and the fourth connector 330, thereby further improving the installation stability of the dust cup device 200.

[0192] In some embodiments, please refer to Figure 19 and Figure 20The fourth connector 330 has a locked state and an unlocked state. When the fourth connector 330 is in the locked state, it can lock the third connector 290 to prevent the dust cup device 200 from accidentally detaching from the fan assembly 300 during operation. When the fourth connector 330 is in the unlocked state, the fourth connector 330 and the third connector 290 are disengaged from each other.

[0193] For example, the fourth connector 330 can rotate relative to the third connector 290 to switch between an unlocked state and a locked state. For instance, the fourth connector 330 is connected to the fan assembly 300 via a rotating shaft 420, the axis of which is perpendicular to both the first direction R1 and the second direction R2, to enable the rotation of the fourth connector 330; or the connection between the fourth connector 330 and the fan assembly 300 can undergo elastic deformation to enable the rotation of the fourth connector 330.

[0194] For example, please read Figure 20 The fourth connector 330 has a locking groove 330a, and the third connector 290 protrudes upward to form a protrusion 290a. When the fourth connector 330 locks the third connector 290, the protrusion 290a is at least partially located within the locking groove 330a.

[0195] In the embodiment of this application, the locking groove 330a and the protrusion 290a cooperate to restrict the movement of the dust cup device 200 along the axial and circumferential directions, thereby further increasing the stability of the dust cup device 200. At the same time, the protrusion 290a of the third connector 290 only needs to protrude a small height to achieve a locking engagement with the locking groove 330a, making the overall structure of the dust cup device 200 relatively flat and convenient for packaging.

[0196] It is understood that, in some embodiments, at least a portion of the fourth connector 330 forming the locking groove 330a can undergo elastic deformation, thereby achieving an interference fit between the fourth connector 330 and the third connector 290.

[0197] For example, at least a portion of the fourth connector 330 forming the locking groove 330a is made of an elastic material, specifically including rubber, elastomeric plastics, elastic foam materials, elastic textiles, etc.

[0198] In some embodiments, please refer to Figure 20 The third connector 290 has a snap-fit ​​groove 290b on the side facing the negative pressure chamber 200b, and the mounting end cover 340 of the fan assembly 300 has a snap-fit ​​protrusion 340a protruding radially upward. When the hook and the connecting groove are snapped together, the snap-fit ​​protrusion 340a is at least partially located in the snap-fit ​​groove 290b.

[0199] In the embodiment of this application, the third connector 290 can be fixed relative to the fan assembly 300 by the cooperation of the fastening groove 290b and the fastening protrusion 340a, thereby increasing the connection strength between the dust cup 210 and the fan assembly 300.

[0200] For example, the engaging groove 290b and the protrusion 290a are located on opposite sides of the third connector 290 in the vertical direction.

[0201] It should be noted that the embodiments of this application do not limit whether the third connector 290 has a snap-fit ​​groove 290b.

[0202] It is understood that, in some embodiments, please refer to Figure 20 A sealing ring 320 is also provided on the rear side of the end cap 340 to improve the sealing effect.

[0203] In some embodiments, please refer to Figure 21 The fourth connector 330 includes a connector head 331, a connector handle 332, and a limiting plate 333. A locking groove 330a is disposed on the connector head 331. The connector handle 332 is used to connect the fan assembly 300. The limiting plate 333 is disposed between the connector head 331 and the connector handle 332 and extends downward along the first direction R1. The locking groove 330a is located on the side of the limiting plate 333 away from the connector handle 332. When the locking groove 330a is engaged with the protrusion 290a, the limiting plate 333 can abut against the mounting end cover 340 of the fan assembly 300 to provide support for the fourth connector 330 and improve assembly strength.

[0204] It should be noted that the mounting end cover 340 of the fan assembly 300 is provided with a flat-bottomed groove 340b at the corresponding position of the limiting plate 333, so as to increase the contact area between the bottom of the limiting plate 333 and the mounting end cover 340 and improve the stability of the support.

[0205] Understandably, please refer to Figure 21 The flat-bottomed groove 340b is located on the rear side of the fastening protrusion 340a. When the third connector 290 and the fourth connector 330 are in the locked state, the protrusion 290a is located in the space formed by the fastening protrusion 340a, the locking groove 330a and the limiting plate 333, thereby making the locking strength higher.

[0206] It is understandable that the fourth connector 330 and the third connector 290 can also be locked and unlocked in other ways, for example, the fourth connector 81 and the third connector 290 can be configured as a pin and a slot.

[0207] In some embodiments, please refer to Figure 21The fourth connector 330 also has two support handles 334 connected to both sides of the connecting handle 332. The support handles 334 are locked in the fan assembly 300. The fourth connector 330 also includes an elastic member 335. The elastic member 335 abuts against the support handles 334 to apply a pushing force to the support handles 334. This pushing force is used to automatically return the fourth connector 330 from the unlocked state to the locked state, realizing automatic reset.

[0208] It is understandable that there can be more than two elastic elements 335, which abut against the two support handles 334 respectively.

[0209] Understandably, please refer to Figure 21 A spring mounting position 337 is provided at the corresponding position of the support handle 334.

[0210] It is understandable that the elastic element 335 is set as an axial compression spring. When the fourth connecting element 330 is in the locked state, the compression force on the compression spring is greater than or equal to 0 Newtons. When the fourth connecting element 330 changes from the locked state to the unlocked state, the compression force on the compression spring will gradually increase.

[0211] In some embodiments, please refer to Figure 21 Both support handles 334 have an end shaft 336 at their free ends. The end shaft 336 is rotatable. It is understood that at least one support handle 334 only needs to have an end shaft 336 at its free end.

[0212] It is also understood that this application does not limit the type of elastic element 335, which can also be a torsion spring.

[0213] It is also understood that the embodiments of this application do not limit whether the fan assembly 300 is provided with the elastic element 335.

[0214] In some embodiments, please refer to Figure 20 The third connector 290 has a first abutment surface 290c, and the fourth connector 330 has a second abutment surface 330b. During the installation of the dust cup device 200, the first abutment surface 290c can apply a pushing force to the second abutment surface 330b, thereby pushing the fourth connector 330 to rotate relative to the fan body. Therefore, when installing the dust cup device 200, the user can press the dust cup device 200 to unlock the fourth connector 330 from a locked state, saving time and effort and providing a better user experience.

[0215] It should be noted that in the above embodiments, please refer to... Figure 20During the process of locking the fourth connector 330 to the third connector 290, the user does not directly apply force to the fourth connector 330. Instead, by applying force to the third connector 290, the user indirectly pushes the fourth connector 330 to rotate relative to the wind turbine body, thereby unlocking the fourth connector 330. It is understandable that, during the above process, the user could also directly apply force to the fourth connector 330, causing it to rotate relative to the wind turbine body, thus unlocking the fourth connector 330.

[0216] Therefore, both of the above installation methods are within the scope of protection of this application.

[0217] Understandably, both the rear end face of the dust cup device 200 and the front end face of the fan assembly 300 are inclined, forming inclined surfaces. Specifically, the distance between the rear end face of the dust cup device 200 and the cylinder cover gradually decreases from top to bottom; similarly, the distance between the front end face of the fan assembly 300 and the cylinder cover gradually decreases from top to bottom. This design avoids interference between the rear end face of the dust cup device 200 and the front end face of the fan assembly 300 when the dust cup device 200 is installed onto the fan assembly 300 from top to bottom. Furthermore, it minimizes the installation gap between the two end faces after installation, improving assembly accuracy.

[0218] The following describes the installation and disassembly process of the dust cup device 200 in detail, based on the above structure:

[0219] During installation, first insert the second connector 220 into the first connector 120 through the slot, and then preliminarily install the front part of the dust cup device 200 on the upper side of the air duct assembly 100.

[0220] Then, the rear section of the dust cup device 200 is rotated downward about the second connector 220 as the axis, so that the first abutment surface 290c abuts against the second abutment surface 330b. Continue to apply downward pressure to the rear section of the dust cup device 200, so that the third connector 290 pushes the fourth connector 330 to rotate. After the dust cup device 200 is installed in place, the fourth connector 330 automatically locks against the third connector 290 under the action of the elastic member 335; or the user can manually rotate the fourth connector 330 to open a certain angle between the fourth connector 330 and the fan assembly 300, and then rotate the other end of the dust cup device 200 downward about the second connector 220 as the rotation center to install the dust cup device 200 in place. The user then releases the fourth connector 330, causing the fourth connector 330 to reset and lock the third connector 290.

[0221] During disassembly, the user can manually rotate the fourth connector 330 to unlock it. Then, holding the dust cup device 200, rotate it upwards around the second connector 220 until the second connector 220 comes out of the slot of the first connector 120.

[0222] For example, please refer to Figure 3 Along the axial direction (i.e., the first direction R1) of the dust cup device 200, the distance between the third connector 290 and the second connector 220 is greater than or equal to half the length of the dust cup 210. This arrangement allows the constraint forces between the air duct assembly 100 and the fan assembly 300 and the dust cup device 200 to be distributed on opposite sides of the dust cup 210, reducing the length of the free end of the dust cup device 200 and thus preventing the dust cup device 200 from shaking during use.

[0223] In some embodiments, please refer to Figure 19 The fan assembly 300 includes a main housing 350, and the main housing 350 has an installation cavity 350a for installing a motor 360 and an impeller. The installation cavity 350a is connected to the negative pressure chamber 200b of the dust cup device 200. One end of the main housing 350 is connected to the dust cup device 200.

[0224] It is understood that in some embodiments, the fourth connector 330 is mounted on the main housing 350.

[0225] It should be noted that during the use of cleaning equipment, static electricity is generated by the friction between the roller brush of the floor brush and the floor or carpet, and static electricity is also generated by the rotation and friction of dust in the connector tube and dust cup 210. If this static electricity is not released in time, the charge will accumulate and be released through tip discharge when it reaches a certain amount. When the user operates the vacuum cleaner, the tip discharge will cause the user to feel an electric shock, affecting the user experience. In order to eliminate this static electricity, the following methods are usually used: 1. Use aluminum foil to stick the anti-static wire to the motor housing 360a to release static electricity. However, the anti-static wire is prone to falling off after the aluminum foil has been used for a long time; 2. Use anti-static material injection molding for the dust cup 210, but its cost is high; 3. A protruding structure is set on the dust cup 210 to place the anti-static plate 370, but the aesthetics are poor.

[0226] In some embodiments, please refer to Figure 22 , Figure 23 and Figure 28 The motor 360 has a conductive motor housing 360a, such as a metal motor housing 360a. A vibration damping structure 360b for shock absorption and noise reduction is provided on the outside of the motor housing 360a. An electrostatic sheet 370 is arranged between the motor housing 360a and the vibration damping structure 360b. The electrostatic sheet 370 is clamped and fixed by the motor housing 360a and the vibration damping structure 360b.

[0227] It is understandable that the electrostatic sheet 370 is connected to the electrostatic release sheet 370a through the conductive structure 370d, and the electrostatic release sheet 370a can be fixed on the handle 500 or other locations that are easily touched by the human body.

[0228] In some embodiments, please refer to Figure 1 A support member 510 is also provided on the front side of the handle 500. The connection between the handle 500 and the fan assembly 300 is located at the front end of the motor 360 along the axial direction, and the connection between the support member 510 and the fan assembly 300 is located at the rear end of the motor 360 along the axial direction. This arrangement improves the stability of the handle 500 and the support member 510 in supporting the cleaning equipment. When the cleaning equipment is equipped with the support 510, the electrostatic discharge sheet 370a can be fixed on the support member 510.

[0229] It should be noted that when the electrostatic discharge plate 370a is fixed on the handle 500 or the support 510, the electrostatic discharge plate 370a is exposed through the hollow part of the handle 500 or the support 510.

[0230] It should also be noted that in some embodiments, the support member 510 is located at the rear of the dust cup device 200. With this arrangement, the support member 510 can provide more stable support for the dust cup device 200 and the fan assembly 300. In addition, during use, the support member 510 can also assist the handle 500 in providing a certain gripping function.

[0231] It should be noted that the support member 510 is tilted backward from top to bottom.

[0232] Understandably, the conductive structure 370d can be a conductive wire, with one end of the conductive wire fixed to the electrostatic sheet 370 by welding, and the other end of the conductive wire fixed to the electrostatic release sheet 370a by welding. In addition to welding, electrical connections between the conductive structure and the electrostatic sheet 370 and the electrostatic release sheet 370a can also be achieved by riveting, screwing, or other methods.

[0233] In this embodiment, after the electrostatic sheet 370 is installed, static electricity at various locations will be continuously transmitted to the user's hand through the electrostatic sheet 370, wire harness, and electrostatic discharge sheet 370a before it accumulates, and can be transmitted to the ground through the human body. This avoids the accumulation of static electricity leading to concentrated discharge and affecting the user experience.

[0234] It is understood that, in some embodiments, please refer to Figure 23The electrostatic sheet 370 includes a substrate 370b and an elastic sheet 370c. In its original state, the elastic sheet 370c can be lifted off the substrate 370b. When subjected to external pressure, the elastic sheet 370c is pressed against the substrate 370b. This design further enhances the friction between the electrostatic sheet 370 and the motor housing 360a and the rubber ring vibration damping structure 360b, making the electrostatic sheet 370 less prone to detachment and improving conductivity.

[0235] It is understandable that the original state refers to the state of the electrostatic sheet 370 before it is installed on the fan assembly 300. It is also understandable that after the electrostatic sheet 370 is installed on the fan assembly 300, due to prolonged pressure from the motor housing 360a and the vibration damping structure 360b, the elastic recovery force of the elastic sheet 370c will deteriorate. After removing the electrostatic sheet 370, the elastic sheet 370c may not noticeably lift off the base plate 370b. However, those skilled in the art will understand that it can lift off the base plate 370b in its original state.

[0236] In some embodiments, please refer to Figure 23 The substrate 370b and the elastic sheet 370c are an integral structural component, for example, the elastic sheet 370c is stamped on a substrate 370b.

[0237] In some embodiments, please refer to Figure 19 and Figure 28 The fan assembly 300 includes a housing 300a, a motor 360 and a fan wheel, both of which are located inside the housing 300a. The vibration damping structure 360b is located inside the housing 300a.

[0238] It should be noted that an air inlet grille 300b is provided on the front side of the housing 300a. The airflow separated and filtered by the dust cup device 200 enters the housing 300a through the air inlet grille 300b. An air outlet is provided on the rear side of the housing 300a. The airflow in the housing 300a can enter the mounting cavity 350a through the air outlet.

[0239] In some embodiments, please refer to Figure 19 Along the first direction R1, the housing 300a together with the motor 360 is located on the side of the mounting bracket 390 away from the cover plate device 400, and the air outlet housing 380 is located on the side of the mounting bracket 390 facing the cover plate device 400 and extends into a housing cavity 380b. An air outlet chamber 390a is formed between the air outlet housing 380 and the mounting bracket 390, and a first through hole 380a is formed on the air outlet housing 380 to connect the air outlet chamber 390a and the housing cavity 380b.

[0240] Understandably, please refer to Figure 19The mounting bracket 390 is provided with a connecting hole to connect the mounting cavity 350a and the air outlet chamber 390a.

[0241] In some embodiments, please refer to Figure 19 The air outlet housing 380 is provided with a first through hole 380a that communicates with the outside world so as to discharge airflow to the outside world.

[0242] In some embodiments, please refer to Figure 25 The receiving cavity 380b is used to house the filter element 800, and the main housing 350 is provided with an air outlet 350b. It should be noted that the filter element 800 refers to a structure that can adsorb fine dust in the airflow.

[0243] In some embodiments, the filter element 800 is a HEPA filter 250 or a sponge.

[0244] It is understood that the embodiments of this application do not limit the type of filter 800.

[0245] Understandably, the filter element 800 is detachably disposed within the receiving cavity 380b so that the user can easily replace the filter element 800.

[0246] Understandably, the filter element 800 can be set to have an aromatherapy function, allowing users to select different aromatherapy scents in addition to filtering the airflow.

[0247] It should be noted that the aromatherapy function can be set up as a separate module placed in the receiving cavity 380b, separate from the filter element 800.

[0248] It is understandable that the filter element 800 can be arranged around the air outlet housing 380, or it can be arranged only at the first through hole 380a and / or the air outlet 350b, so as to filter the airflow discharged from the cleaning equipment again and further improve the dust removal capability.

[0249] In the embodiment of this application, the filter element 800 is annular and can be well covered around the air outlet housing 380, so that the airflow from the air outlet chamber 390a to the outside passes through the filter element 800, thereby improving the filtration effect.

[0250] It is understood that the embodiments of this application do not limit the shape of the filter element 800.

[0251] It is understood that the main housing 350 of the embodiments of this application can be configured as an integral structure or a split structure. When the main housing 350 is configured as a split structure, the housing of the receiving cavity 380b can be formed separately from a part of the main housing 350, thereby facilitating processing and manufacturing.

[0252] In some embodiments, please refer to Figure 19 , Figures 25 to 27 The fan assembly 300 is provided with a cover plate device 400 at its rear end. The cover plate device 400 is movably installed on the main housing 350 to cover the opening 380c of the receiving cavity 380b.

[0253] In some embodiments, please refer to Figure 25 and Figure 27 The cover plate device 400 has a first state and a second state. When the cover plate device 400 is in the first state, the cover plate device 400 closes the opening 380c. When the cover plate device 400 is in the second state, the cover plate device 400 opens the opening 380c. The filter element 800 can be moved into or out of the receiving cavity 380b from the opening 380c.

[0254] In some embodiments, please refer to Figure 19 , Figure 28 and Figure 29 The display component 900 is mounted on the cover plate device 400, and the display component 900 is located on the side of the cover plate device 400 opposite to the receiving cavity 380b. It should be noted that the display component 900 refers to a structure that can display the current status of the cleaning equipment.

[0255] For example, the current status of the cleaning device includes the remaining battery power, cleaning mode, and on / off status. In some embodiments, the display component 900 can display multiple current statuses of the cleaning device, allowing the user to intuitively understand the current status of the cleaning device.

[0256] In this embodiment, the display component 900 is mounted on the cover plate device 400, and the display component 900 is located on the side of the cover plate device 400 opposite to the receiving cavity 380b. During use, the user can easily and clearly see the current status of the cleaning equipment. In the prior art, when the display component 900 is not on the cover plate device 400, for example, on one side of the main housing 350, the user needs to turn to the side each time they want to check, and may even need to pause the operation before checking, which is inconvenient.

[0257] Understandably, in order to improve the filtration effect, the filter element 800 fills the entire receiving cavity 380b. When the display component 900 is set on one side of the main housing 350, it will occupy the circumferential space of the receiving cavity 380b, thereby reducing the installation space of the filter element 800 and thus affecting the filtration effect.

[0258] In some embodiments, please refer to Figures 27 to 29 The display component 900 is located above the handle 500. The position of the display component 900 is more in line with the user's usage habits. The user can easily observe the display component 900 while holding the handle 500, which reduces the obstruction of the user's line of sight by the user's arm and provides a better user experience.

[0259] In some embodiments, the display component 900 also has control buttons.

[0260] Understandably, the control buttons include physical buttons or touch controls. This design allows users to easily operate and control the cleaning equipment.

[0261] In some embodiments, the display component 900 is an electronic display screen.

[0262] For example, the electronic display screen is a color display screen.

[0263] For example, the electronic display screen is a touch screen, which allows the user to switch the cleaning functions of the cleaning equipment by touching it.

[0264] It is understood that the embodiments of this application do not limit the type of display screen. Exemplarily, the display screen includes a plurality of indicator lights arranged at intervals between each other, each indicator light having a different color.

[0265] For example, when projected along the axial direction of the receiving cavity 380b, the projection area of ​​the display component 900 is approximately circular.

[0266] In the embodiments of this application, the display component 900 can make full use of the surface of the cover plate device 400 on the side opposite to the receiving cavity 380b along the axial direction of the receiving cavity 380b, and the display screen can be as large as possible, so that the user can observe the display screen more clearly.

[0267] In some embodiments, the projection area of ​​the display component 900 overlaps with the projection area of ​​the cover plate device 400 when projected along the axial direction of the cover plate device 400. It is understood that the overlap of the projection area of ​​the display component 900 with the projection area of ​​the cover plate device 400 in the embodiments of this application includes the case where the projection area of ​​the display component 900 is smaller than the projection area of ​​the cover plate 410 body and is located therein.

[0268] In some embodiments, please refer to Figure 25 The cover plate device 400 is rotatably mounted on the main housing 350.

[0269] Understandably, rotating the cover plate device 400 by applying external force allows the cover plate device 400 to switch between the first and second states, making it convenient to replace the filter element 800 and providing a better user experience.

[0270] It is understood that the embodiments of this application are not limited to the cover plate device 400 being rotatably mounted on the main housing 350. Exemplarily, the cover plate device 400 and the main housing 350 are configured to have mutually cooperating grooves and sliders, by moving the slider to enable the cover plate device 400 to move relative to the main housing 350, and when the cover plate device 400 moves away from the main housing 350, the cover plate device 400 switches from a first state to a second state.

[0271] In some embodiments, please refer to Figure 19 , Figure 24 and Figure 25 The cover plate device 400 includes a cover plate 410, a rotating shaft 420, and a connector 430 connecting the cover plate 410 and the rotating shaft 420. The cover plate 410 can be rotated and opened via the rotating shaft 420, and the display component 900 is disposed on the cover plate 410.

[0272] Understandably, the shaft 420 can be mounted on the fan assembly 300 or the handle 500.

[0273] In some embodiments, please refer to Figure 24 The connector 430 has a cable tray 430a, which is used to accommodate the power supply cable 610 so that the power supply cable 610 can be electrically connected to the display component 900. On the one hand, the connector 430 provides protection for the cable, making it safe and reliable. On the other hand, it avoids the cable from being exposed, making the cleaning equipment simple and beautiful.

[0274] For example, the pivot 420 is connected to the end of the connector 430 away from the cover plate 410.

[0275] In the embodiment of this application, the rotation axis 420 is as far away from the cover plate 410 as possible, which can increase the rotation range of the cover plate 410, thereby making it easier for the filter element 800 to move into or out of the receiving cavity 380b, and reducing the interference of the cover plate 410 on the filter element 800.

[0276] For example, please refer to Figure 24 and Figure 25 A cover structure 380d is provided on the side wall of the receiving cavity 380b, and a third opening 380e is provided on the cover structure 380d for the connector 430 to pass through. The connector 430 includes an arc-shaped segment 430b and a straight segment 430c connected to each other. The arc-shaped segment 430b passes through the third opening 380e, and the rotating shaft 420 is connected to the end of the straight segment 430c away from the arc-shaped segment 430b. The above arrangement helps to reduce the interference range of the connector 430 during the rotation of the cover plate device 400, minimize the size of the third opening 380e, and improve the sealing performance of the receiving cavity 380b.

[0277] It is understandable that when a cover structure 380d is provided on the side wall of the receiving cavity 380b, the annular filter element 800 is provided with a clearance notch to avoid the cover structure 380d.

[0278] For example, the rotation center axis of the rotating shaft 420 is arranged to intersect with the axis of the main housing 350 of the fan assembly 300, for example, to be arranged perpendicular to each other. It is understood that the cover plate 410 can be flipped up or down.

[0279] For example, please refer to Figure 19 The rotation center axis of the rotating shaft 420 is arranged along the third direction R3, which is perpendicular to both the first direction R1 and the second direction R2.

[0280] For example, the rotation center axis of the rotating shaft 420 can be arranged along the first direction R1, and the cover plate device 400 can be rotated to the side to open the opening 380c, that is, the cover plate device 400 rotates around the first direction.

[0281] Understandably, depending on actual needs, the rotation center axis of the rotating shaft 420 can be arranged in other directions, such as along the second direction R2 on one side of the main housing 350, and the cover plate device 400 can be flipped open from the left or right.

[0282] In some embodiments, please refer to Figure 25 and Figure 26 The cover plate device 400 also includes a first fixing member 440, which is movably disposed on the cover plate 410. A second fixing member 310 is disposed on the main housing 350 of the fan assembly 300. When the cover plate device 400 is in the first state, the first fixing member 440 is used to engage with the second fixing member 310 to lock the cover plate device 400, so that the cover plate device 400 can be maintained in the first state relatively stably.

[0283] In some embodiments, please refer to Figure 25 The first fixing member 440 is set as a locking ring. The display component 900 is fixedly connected to the cover plate 410. The diameter of the display component 900 is smaller than the diameter of the cover plate 410. The locking ring is set around the display component 900 and can rotate around the display component 900 by a predetermined angle. The locking ring is provided with a locking protrusion 442a. The second fixing member 310 is set as a slot on the main housing 350. Through the rotation of the locking ring and the cooperation between the locking protrusion 442a and the slot, the locking and unlocking of the cover plate device 400 and the main housing 350 can be realized.

[0284] Understandably, the locking ring can rotate around the display component 900, but it is still confined to the cover plate 410 to prevent the locking ring from automatically falling off the cover plate 410.

[0285] In some embodiments, please refer to Figure 25 The locking ring includes an inner ring 442 and an outer ring 441. The outer ring 441 is used for user gripping and operation. A locking protrusion 442a is provided on the outer side wall of the inner ring 442, and a locking groove is provided on the inner side wall of the main housing 350.

[0286] Understandably, the 442a protrusion can be set to various shapes, for example... Figure 25 The shape shown is long and narrow, but it can also be cylindrical or other shapes.

[0287] In some embodiments, please refer to Figure 25 In order to avoid the connector 430, the locking ring is provided with an avoidance opening 440a. It can be understood that in order to avoid interference between the locking ring and the connector 430 when the locking ring rotates, the width of the avoidance opening 440a is greater than the width of the connector 430.

[0288] It is understood that the embodiments of this application do not limit whether the first fastener 440 is circumferentially surrounding the cover plate 410 and is rotatable relative to the cover plate 410.

[0289] In some embodiments, the cover plate 410 is provided with a heat dissipation hole (not shown) on the side facing the receiving cavity 380b, which can be used to improve the heat dissipation effect of the display component 900.

[0290] In some embodiments, please refer to Figure 1 and Figures 27 to 29 The cleaning equipment has a handle 500, which is connected to the underside of the fan assembly 300 and the cover plate device 400.

[0291] For example, please refer to Figure 27 To make it easier for users to hold the handle 500, the handle 500 is designed to be curved.

[0292] Please see Figure 29 Specifically, in the embodiments of this application, the center line P2 of the handle 500 is curved into an arc. In some embodiments, the center line P2 of the handle 500 is an arc, and the center of the circle containing the arc is located on the front side of the handle 500. The extension line P3 of the arc does not intersect the axis O of the motor 360, that is, the circle containing the arc is separate from the axis of the motor 360, so as to improve the grip of the cleaning device. The center line of the handle 500 is approximately an arc.

[0293] It should be noted that the axis O of the main housing 350 and the axis of the dust cup device 200 can be set to coincide or not coincide.

[0294] In some embodiments, please refer to Figure 28 and Figure 29The handle 500 has a first side 500a and a second side 500b facing away from each other. The first side 500a is located on the rear side of the handle 500 and is constructed as an arc surface.

[0295] In some examples, both the first side 500a and the second side 500b can be set as curved surfaces.

[0296] Understandably, the second side 500b may be provided with a gripping portion suitable for finger gripping, for example, forming at least one groove to facilitate finger gripping.

[0297] In some embodiments, please refer to Figure 29 The central axis of the rotating shaft 420 of the cover plate device 400 is located inside the handle 500.

[0298] In some embodiments, please refer to Figure 28 and Figure 29 The handle 500 has an internal mounting position for the rotating shaft 420 to be installed. Understandably, to accommodate the shape and rotation trajectory of the connector 430, the upper end of the handle 500 has a receiving space 500d for the arc-shaped segment 430b and the straight segment 430c. When the cover plate device 400 is in the first state, both the straight segment 430c and the arc-shaped segment 430b are located within the receiving space 500d, with the straight segment 430c approximately parallel to the bottom wall of the receiving space 500d. When the cover plate device 400 is in the second state, the arc-shaped segment 430b is at least partially moved out of the receiving space 500d, and the straight segment 430c is approximately perpendicular to the bottom wall of the receiving space 500d.

[0299] In some embodiments, please refer to Figure 28 and Figure 29 The handle 500 has a mounting position for mounting the electrostatic discharge plate 370a near the second side 500b, for example, on the inner side of the second side 500b. The second side 500b has a notch for exposing the electrostatic discharge plate 370a so that when the user holds the handle 500, the electrostatic discharge plate 370a can come into contact with it.

[0300] It is understandable that the electrostatic discharge sheet 370a can also be exposed from the first side 500a, or from other places on the handle 500, as long as it is a position that allows the human body to frequently come into contact with the electrostatic discharge sheet 370a.

[0301] In some embodiments, please refer to Figure 28 and Figure 29The support member 510 is connected at one end to the power supply component 600 and at the other end to the fan component 300. Since the handle 500 and the support member 510 are jointly supported between the power supply component 600 and the fan component 300, the overall structural strength of the cleaning equipment is improved. It is understood that the power supply component 600 can provide power to the fan component 300 and the display component 900, etc.

[0302] In some embodiments, please refer to Figure 28 and Figure 29 The power supply assembly 600 includes a battery compartment 620, a power supply battery 630, and a battery management system (not shown in the figure). Both the power supply battery 630 and the battery management system are located within the battery compartment 620. The battery management system is electrically connected to both the power supply battery 630 and the power supply line 610. For example, the battery management system is an electronic control board, and the battery can be a cylindrical battery or a wound cell.

[0303] It is understandable that multiple power supply batteries 630 can be provided, and multiple power supply batteries 630 can be arranged side by side along the arrangement direction of the power supply batteries 630. This arrangement can make better use of the volume of the battery compartment 620.

[0304] For example, multiple power supply batteries 630 are arranged side by side along the first direction, increasing the flat area of ​​the battery compartment 620, which facilitates the placement of cleaning equipment when the power supply component 600 is used as a base, thereby improving the stability of the placement.

[0305] In some embodiments, please refer to Figure 28 and Figure 29 The motor 360 is located in front of the center of gravity Q of the power supply battery 630. During use, the cleaning device needs to be tilted forward and downward; this design allows the user to perform this action more effortlessly.

[0306] In some embodiments, please refer to Figure 28 and Figure 29 The center of gravity Q of the power supply battery 630 is located on the front side of the handle 500 grip, which makes it easier for users to clean when using the cleaning equipment.

[0307] In some embodiments, in order to facilitate charging of the power supply component 600, the charging connector 640 is located on the lower front end of the air duct assembly 100. A cover structure 140 is provided on the lower side of the air duct assembly 100. The charging cable electrically connected to the charging connector 640 runs inside the cover structure 140. The right end of the cover structure 140 is connected to the support member 510. The charging cable continues to run inside the support member 510 and reaches the power supply component 600.

[0308] It is understandable that when the support 510 is not provided, the cover structure 140 can be directly connected to the handle 500, and the charging cable can continue to run along the inside of the handle 500 to reach the power supply component 600.

[0309] In some embodiments, please refer to Figure 29 In the diagram, arrow P1 indicates the airflow direction. The handle 500 is connected to the outer wall of the main housing 350. A first through-flow air passage 500c is provided inside the handle 500. A fourth opening 350c is opened on the lower side wall of the receiving cavity 380b, and the fourth opening 350c is connected to the receiving cavity 380b. Simultaneously, the battery compartment 620 is connected to the first air passage 500c. Therefore, the airflow exiting the fourth opening 350c can reach the battery compartment 620 along the first air passage 500c, improving the heat dissipation effect of the power supply battery 630.

[0310] In some embodiments, please refer to Figure 28 and Figure 29 The battery compartment 620 has a first opening 620a and a second opening 620b. The first opening 620a communicates with the first air passage 500c and the inner cavity of the battery compartment 620, respectively. The second opening 620b communicates with the outside and the inner cavity of the battery compartment 620, respectively.

[0311] In the embodiments of this application, the first opening 620a can gather airflow to a certain extent, thereby increasing the airflow velocity and improving the heat dissipation efficiency of the power supply battery 630. It is understood that the first opening 620a is located at one end of the battery compartment 620, and the second opening 620b is located at the other end of the battery compartment 620 to further enhance the convection velocity. It should be noted that the embodiments of this application are not limited to the first opening 620a being located at one end of the battery compartment 620 and the second opening 620b being located at the other end. Exemplarily, the second opening 620b and / or the first opening 620a are located between opposite ends of the battery compartment 620.

[0312] In related technologies, heat dissipation of the battery pack is achieved by blowing air from a fan onto the surface of the battery pack, thereby removing the heat generated during operation. Since the fan draws air from the outside into the vacuum cleaner, it carries a large amount of dust and debris. The dust cup device 200 contains a filter. A cyclone separator initially separates the air from the dust and debris, and then the filter further filters the separated air to remove large dust particles. The airflow passing through the filter is then introduced into the battery compartment to dissipate heat from the powered batteries. However, the airflow after filtration still carries some fine dust. This fine dust, blown directly onto the surface of the battery management system board, can easily cause contamination and lead to a short circuit in the battery management system. Furthermore, this fine dust can leak from the opening connecting the battery compartment to the outside, causing secondary pollution.

[0313] In some embodiments, to resolve the above issues, please refer to Figure 25 and Figure 26 A filter element 800 is provided inside the cavity 380b. The filter element 800 can be arranged around the air outlet housing 380 or at the fourth opening 350c and / or the air outlet 350b to filter the airflow entering the first air passage 500c again, further improving the dust removal capability and minimizing the amount of fine dust reaching the battery compartment 620, thereby reducing the impact of fine dust on the power supply battery 630 and the battery management system.

[0314] For example, as described above, the cleaning equipment also includes a motor pre-filter 291, which is disposed between the dust cup device 200 and the fan assembly 300 to filter the airflow flowing from the dust cup device 200 to the fan assembly 300, thereby performing a first pre-filtration. The airflow entering the first air passage 500c is further filtered by the filter 800 disposed in the receiving cavity 380b, which greatly improves the filtration effect.

[0315] In some embodiments, a filter structure may be further provided within the first airway 500c.

[0316] In some embodiments, please refer to Figures 24 to 26 A cover structure 380d is provided on the lower side wall of the receiving cavity 380b, and a second through hole 380f is provided on the cover structure 380d. At this time, the fourth opening 350c is located in the area covered by the cover structure 380d on the lower side wall of the receiving cavity 380b. The fourth opening 350c also provides clearance space for the connector 430 to pass through. Specifically, the fourth opening 350c provides clearance space for the arc-shaped segment 430b.

[0317] It is understood that, for the above embodiment with the second through hole 380f, the filter element 800 can be disposed at the second through hole 380f.

[0318] It is also understood that, in the above embodiment, the airflow filtered by the filter element 800 passes through the second through hole 380f and the fourth opening 350c in sequence before entering the first air passage 500c.

[0319] In some embodiments, please refer to Figure 28 and Figure 29 The upper part of the handle 500 is provided with an arc-shaped section 430b and a straight section 430c, which is a accommodating space 500d. The accommodating space 500d is part of the first air passage 500c. The accommodating space 500d is directly connected to the fourth opening 350c. The lower side wall of the accommodating space 500d is provided with a connecting hole 500e.

[0320] In some embodiments, a second air passage may be provided inside the support member 510. Specifically, the upper end of the handle 500 has an accommodating space 500d formed by an arc-shaped segment 430b and a straight segment 430c. The accommodating space 500d is directly connected to the fourth opening 350c. The front sidewall of the accommodating space 500d has a connecting hole that communicates with the second air passage inside the support member 510, thereby allowing airflow to reach the battery compartment 620 through the second air passage. It is understood that the first air passage 500c and the second air passage can be provided simultaneously inside the handle 500 and the support member 510, providing multiple channels to reach the battery compartment 620. It is also understood that when the second air passage is provided, the first air passage 500c inside the handle 500 can also be blocked.

[0321] In some embodiments, the first airway 500c can be replaced by an air tube 520, that is, the air inlet end of the air tube 520 is directly connected to the fourth opening 350c, and the air tube 520 is inserted into the handle 500 and / or the support 510, reaching the battery compartment 620.

[0322] Understandably, the air inlet of the air tube 520 may not be directly connected to the fourth opening 350c, but rather to the side wall of the accommodating space 500d at the upper end of the handle 500. This arrangement allows the air tube 520 to be directly assembled with the internal structure of the handle 500, facilitating the modular production and assembly of the handle 500.

[0323] It should be noted that a filtration structure can be further installed inside the trachea 520 to improve the filtration effect.

[0324] In some embodiments, a third air passage may be provided inside the support member 510. The outlet end of the third air passage may be connected to the front of the main housing 350, and the intake end may be connected to the battery compartment 620, so as to use vacuum suction to draw outside air into the battery compartment 620, providing heat dissipation airflow for the power supply component 600, and greatly improving the cooling effect of the power supply battery 630.

[0325] Understandably, please refer to Figure 28 The third airway can be set as trachea 520.

[0326] For details, please refer to Figure 28 In the main housing 350, an air inlet space is provided on the side of the impeller facing the dust cup device 200. A negative pressure zone is formed in the air inlet space. The air outlet of the air pipe 520 is connected to the air inlet space. Compared with the pressure of the receiving cavity 380b, the suction of the air inlet space is stronger, so the cooling effect on the power supply battery 630 is better.

[0327] In some embodiments, an air inlet grille is provided on the side of the impeller facing the dust cup device 200, and the air inlet space is formed in front of the air inlet grille. The airflow filtered by the motor pre-filter 291 will enter the mounting cavity 350a through the air inlet grille, and the air outlet end of the air pipe 520 is connected to the air inlet space.

[0328] Understandably, the main housing 350 has a through hole through which the air supply pipe 520 passes.

[0329] In some embodiments, a sealing ring is provided at the through hole to seal the gap through which the air pipe 520 passes.

[0330] In some embodiments, please refer to Figure 28 The support member 510 has a channel inside for accommodating the air tube 520. A fixing member is provided in the channel to limit the air tube 520 and make it stably placed in the channel.

[0331] In some embodiments, please refer to Figure 28 The handle 500 is equipped with a wire for transmitting power from the power supply component 600 to the display component 900, the fan component 300, etc. The wire is connected to the battery compartment 620 through an opening and is electrically connected to the power supply battery 630. This opening is located at the connection between the battery compartment 620 and the handle 500. The first opening 620a is the aforementioned opening, thereby avoiding the need to open a separate first opening 620a.

[0332] In some embodiments, please refer to Figure 28 The first opening 620a is located at the connection between the battery compartment 620 and the handle 500; the lower ends of the support 510 and the handle 500 are connected by a connecting shell, and a wiring space is formed between the connecting shell and the upper side wall of the battery compartment 620. The air tube 520 bends at the connection between the support 510 and the battery compartment 620, and then extends along the wiring space to the first opening 602a and connects with the first opening 602a.

[0333] The following explains the airflow direction as it enters the cleaning equipment. It can be understood that during use, the cleaning equipment is tilted forward and downward.

[0334] For example, during the use of the cleaning equipment, the fan assembly 300 generates negative pressure, and airflow enters the air duct assembly 100 from the air inlet, flowing along the air inlet channel 110a of the air duct assembly 100 to the dust cup 210. The airflow first enters the first dust collection chamber 210c, undergoes primary cyclone separation through the first separator 241, and large dust particles settle to the bottom of the first dust collection chamber 210c. Then, the unseparated fine dust is carried by the air through the second separator 242, undergoing secondary cyclone separation. Specifically, the air spirals down along the guide vanes in the channel 242b of the second separator 242, and the dust settles to the bottom of the second dust collection chamber 242c. After the second separation, the airflow undergoes primary filtration through the motor pre-filter 291, and then flows into the mounting cavity 350a through the air inlet grille. Specifically, the airflow first flows into the receiving shell 300a through the air inlet grille, then flows out from the rear side of the receiving shell 300a and enters the mounting cavity 350a. The airflow flows from the mounting cavity 350a to the air outlet shell 380, then through the first through hole 380a of the air outlet shell 380 to the receiving cavity 380b. After passing through the filter element 800 for a second filtration, part of the airflow after the second filtration flows to the outside from the air outlet, and the other part flows to the battery compartment 620 along the air passage formed by the handle 500 and / or the support 510. Specifically, the airflow enters the inner cavity of the battery compartment 620 through the first opening 620a, and then flows to the outside through the second opening 620b.

[0335] It should also be noted that the cleaning device of this application can specifically be a pistol-shaped cleaning device. When not in use or during a pause in use, this device is often placed horizontally with the power supply component 600 as its base. However, in existing cleaning devices, the motor's axis is parallel to the placement plane V. This can easily cause the device to tip forward, especially when the dust cup 210 contains a large amount of dust and debris. To solve this problem, existing technologies often require adding an extra structure at the rear of the power supply component 600 to ensure horizontal placement of the vacuum cleaner. However, this increases costs and unnecessarily increases the size and weight of the cleaning device.

[0336] Therefore, in some embodiments of this application, reference is made to Figure 29 As shown, the axis O of the motor 360 makes an angle β with the placement plane V, where β > 0°. This design shifts the vacuum cleaner's center of gravity backward, facilitating horizontal placement.

[0337] It is understandable that β can be 0.5°, 1°, 2°, 5°, etc.

[0338] Meanwhile, to achieve "180° flat" cleaning, while ensuring the cleaning equipment is placed horizontally without tilting forward, the included angle β of the fan assembly 300's axis can be further increased, compressing the length of the power supply assembly 600 and handle 500 protruding backward from the cover plate device 400, i.e., compressing the rear space of the cover plate device 400. In some embodiments, β satisfies: 5° ≥ β ≥ 1°, for example, 1°, 2°, 3°, 5°, etc.

[0339] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and all should be covered within the scope of the specification of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of protection.
