[0070] The present application intends to provide a cleaning device, which is used to clean a surface to be cleaned, and the cleaning device can generate negative pressure to allow dust and debris on the surface to be cleaned to enter the interior of the cleaning device.

[0071] Illustratively, the surface to be cleaned may be a floor or a carpet.

[0072] For example, see Figure 1 The cleaning equipment mainly includes the following working parts: an air duct assembly 100, a dust cup device 200, a fan assembly 300, a cover device 400, a handle 500 and a power supply assembly 600.

[0073] The functions of the above main working parts of the cleaning equipment are as follows:

[0074] For example, see Figure 3 The air duct assembly 100 includes an air duct 110, which forms an air inlet channel 110a. The air duct assembly 100 is used to guide the air flow so that the air carrying dust and debris enters the air inlet channel 110a and then passes through the dust cup device 200 through the air inlet channel 110a.

[0075] Illustratively, the dust cup device 200 can perform cyclonic separation on the dust gas so as to separate the dust and debris from the airflow, and the separated airflow will flow to the fan assembly 300.

[0076] It should be noted that, in some embodiments, please refer to Figures 1 to 3The central axis of the dust cup device 200 and the central axis of the air duct assembly 100 are staggered with each other. When the overall length of the cleaning device is constant, the size of the dust cup device 200 along the central axis of the dust cup device 200 can be increased as much as possible. The dust cup device 200 can accommodate more dust and debris, alleviating the problem that the user needs to frequently disassemble the dust cup device 200 for dust removal. At the same time, such a setting can facilitate the user to disassemble and install the dust cup device 200. It will be understood that the embodiments of the present application are not limited to the central axis of the dust cup device 200 and the central axis of the air duct assembly 100 being staggered with each other. In some embodiments, the central axis of the dust cup device 200 and the central axis of the air duct assembly 100 may coincide.

[0077] 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 .

[0078] For example, see Figure 1 The cover plate device 400 is located on the rear side of the fan assembly 300 .

[0079] For example, a handle 500 is provided on the lower side of the fan assembly 300 . The handle 500 refers to a portion for a user to hold. The user can move the cleaning device by holding the handle 500 to clean the surface to be cleaned.

[0080] Exemplarily, the lower side of the handle 500 further has a power supply assembly 600 to provide power to the blower assembly 300 and the like.

[0081] The following introduces each working component one by one according to the flow direction of airflow in the cleaning equipment.

[0082] First, see Figure 3 , which schematically illustrates an air duct assembly 100, wherein the central axis of the air duct assembly 100 and the central axis of the dust cup device 200 are staggered with each other, see further Figures 3 to 11 The air duct assembly 100 includes an air duct 110, which includes a first tube body 111 and a second tube body 112. One end of the second tube body 112 is connected to one end of the first tube body 111, thereby achieving airflow change. For details, please refer to Figure 3The inhaled 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 degrees or 90 degrees, etc., which is not limited here. In this embodiment, by designing the air duct 110 as a split structure, the first tube body 111 and the second tube body 112 can be manufactured independently in the mold, which reduces the difficulty of demolding the air duct 110. Compared with making the air duct a one-piece structure, the inner tube wall formed by integral demolding can make the inner tube wall of the first tube body 111 and the second tube body 112 smoother, thereby improving the smoothness of air flow and improving the cleaning effect of the cleaning equipment.

[0083] It should be noted that the front end of the air duct 110 can be connected to one or more plug-in tubes, and the front end of the plug-in tube can be further connected to a floor brush, etc., to adapt to different application scenarios.

[0084] In some embodiments, see Figure 3 Since the first tube body 111 and the second tube body 112 need to realize the diversion of airflow, in order to ensure the smooth flow of dust and reduce the stagnation of impurities, the internal channel is set to an arc transition.

[0085] Specifically, in some embodiments, see Figure 3 and Figure 8 At the connection portion between the first tube body 111 and the second tube body 112, at least a portion of the inner sidewall of the first tube body 111 facing the second tube body 112 is configured as an arcuate surface. It should be noted that the arcuate surface is located behind the central axis of the second tube body 112.

[0086] In some other embodiments, see Figure 3 and Figure 10 At the connection portion between the first tube body 111 and the second tube body 112, at least a portion of the inner sidewall of the second tube body 112 facing the first tube body 111 is configured as an arcuate surface.

[0087] It is understandable that the arc can be a segment of a circle, or can be a nearly smooth transition line or other smooth curve formed by connecting multiple arcs of circles or multiple lines.

[0088] In some embodiments, see Figure 3The connection between the first tube body 111 and the second tube body 112 is configured as an arc-shaped structure 113. The arc-shaped structure 113 includes a first curved surface portion 113a and a second curved surface portion 113b. The first curved surface portion 113a and the second curved surface portion 113b are located on opposite sides of the arc-shaped structure 113. It is understood that the first curved surface portion 113a refers to the portion connected to the first tube body 111 and curved toward the second tube body 112; the second curved surface portion 113b refers to the portion connected to the second tube body 112 and curved toward the first tube body 111.

[0089] Exemplarily, the first curved surface portion 113 a and the first tube body 111 are integrally formed.

[0090] Exemplarily, the second curved surface portion 113 b and the second tube body 112 are integrally formed.

[0091] In some embodiments, see Figure 3 and Figure 7 The first tube body 111 includes a straight tube section 111f. The length of the straight tube section 111f is greater than the arc length of the first curved surface section 113a. This makes it easier for the vacuum cleaner to reach locations that are farther away, thereby expanding the cleaning range and reducing the need for the user to bend significantly when using the vacuum cleaner. The straight tube section 111f refers to the portion of the first tube body 111 extending along the first direction R1.

[0092] It is understood that the embodiment of the present application does not limit the length of the straight pipe section 111f to be greater than the arc length of the first curved surface section 113a. For example, the length of the straight pipe section 111f is less than or equal to the arc length of the first curved surface section 113a.

[0093] In some embodiments, see Figure 3 and Figure 4 The first curved surface portion 113a includes a first end surface 111a, and the second curved surface portion 113b includes a second end surface 112a. The first end surface 111a and the second end surface 112a are attached to each other.

[0094] In the embodiment of the present application, the first end face 111a and the second end face 112a are fitted together, so that the air duct 110 has better sealing performance, which alleviates the situation where the air flow moves in the gap between the first tube body 111 and the second tube body 112.

[0095] In some embodiments, see Figure 7 The first end surface 111a includes a first region surface 111b and a second region surface 111c connected to each other, and an angle formed by the intersection of the first region surface 111b and the second region surface 111c is an obtuse angle.

[0096] It should be noted that the first regional surface 111b and the second regional surface 111c can be a plane or an arc surface. When the first regional surface 111b and / or the second regional surface 111c are arc surfaces, the angle formed by the first regional surface 111b and the second regional surface 111c toward the second end surface 112a is the angle formed by the corresponding tangent surface of the arc surface at the intersection of the first regional surface 111b and the second regional surface 111c.

[0097] In the embodiment of the present application, by setting the included angle between the first region surface 111b and the second region surface 111c to be an obtuse angle, the first end surface 111a and the second end surface 112a can be easily fitted together. Furthermore, the obtuse angle can reduce the processing requirements for the mold, simplify demolding, and reduce stress concentration.

[0098] It is understood that the embodiment of the present application does not limit the angle between the first region surface 111b and the second region surface 111c to be an obtuse angle. For example, the angle between the first region surface 111b and the second region surface 111c can be a right angle or an acute angle.

[0099] In some embodiments, see Figure 6 and Figure 8 A sealing member (not shown) 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 111 d for accommodating the sealing member. Specifically, the sealing groove 111 d is provided on the first end surface 111 a .

[0100] Illustratively, the seal is an O-ring.

[0101] Exemplarily, the sealing member is made of silicone or rubber.

[0102] In the solution of the embodiment of the present application, by adding a seal between the second tube body 112 and the first tube body 111, the seal can further increase the sealing between the first tube body 111 and the second tube body 112, thereby preventing dust from leaking from between the first tube body 111 and the second tube 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.

[0103] It is understandable that the embodiments of the present application do not limit whether a seal is provided between the second tube body 112 and the first tube body 111 .

[0104] In some embodiments, see Figure 5 and Figure 6 A boss 111e is provided at the connecting end of the first tube body 111 and the tube body 112, a sealing groove 111d is provided on the boss 111e, and a connecting portion 112b is provided on the second tube body 112, which can be adapted to be connected to the boss 111e.

[0105] It can be understood that the connecting portion 112b is disposed on the second end surface 112a.

[0106] In the embodiment of the present application, by providing the sealing groove 111d on the boss 111e, the strength of the first tube 111 can be ensured even when the sealing groove 111d is provided. Furthermore, the boss 111e can also improve the connection reliability between the first tube 111 and the second tube 112.

[0107] It is understandable that the embodiments of the present application do not limit whether the outer wall of the first tube body 111 is provided with the boss 111 e .

[0108] In some embodiments, see Figure 5 The connecting portion 112b includes a protrusion 112c, which is used to cooperate with the sealing groove 111d to compress the seal, thereby reducing the gap between the first tube body 111 and further improving the sealing performance.

[0109] It is understandable that the embodiments of the present application do not limit whether the connecting portion 112b is provided with the protrusion 112c.

[0110] In some embodiments, the first tube body 111 and the second tube body 112 can be fastened together by a buckle structure, which can be provided in one or more ways.

[0111] In some embodiments, see Figures 6 to 11 The first tube 111 is provided with a first locking protrusion 1110, wherein the first locking protrusion 1110 is located on one side of the first tube 111 along the first direction R1 and protrudes from the first tube 111 along the first direction R1 (specifically, the rear). Exemplarily, two first locking protrusions 1110 are provided, one on each side along the third direction R3. It is understood that there may be more than three first locking protrusions 1110. The second tube 112 is provided with a first clamping member 1121, which is provided with a clamping hole 1121a. The clamping hole 1121a is configured to engage with the first locking protrusion 1110, so that the inner walls of the clamping hole 1121a retain the first locking protrusion 1110 in place. It is understood that the number of first clamping members 1121 is the same as the number of first locking protrusions 1110.

[0112] In some embodiments, see Figures 6 to 11The first tube 111 is also provided with a second locking protrusion 1111. The second locking protrusion 1111 is located on the other side (specifically, the front) of the first tube 111 along the first direction R1, and the second locking protrusion 1111 protrudes from the first tube 111 in a direction perpendicular to the first direction R1. Exemplarily, two second locking protrusions 1111 are provided, one on each side along the third direction R3. It is understood that there may be more than three second locking protrusions 1111. The second tube 112 is provided with a second clamping member 1120. The second clamping member 1120 is provided with a hook 1120a, which abuts the lower end surface of the first locking protrusion 1110. It is understood that the number of second clamping members 1120 is the same as the number of second locking protrusions 1111.

[0113] During installation, the card hole 1121a is placed on the first locking protrusion 1110, and then the second tube body 112 is rotated until the hook 1120a is engaged with the second locking protrusion 1111, completing the assembly of the first tube body 111 and the second tube body 112, and can realize mutual limitation of the first tube body 111 and the second tube body 112 in multiple directions.

[0114] It is understandable that the embodiments of the present application do not limit the assembly method between the first tube body 111 and the second tube body 112. For example, the first tube body 111 and the second tube body 112 can also be fixedly connected by screws or pins.

[0115] In some embodiments, see Figure 3 The cleaning device further includes a sensor 700, which is mounted 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.

[0116] It is understandable that the cleaning device is also provided with a cable (not shown in the figure), which is used to connect components such as the sensor 700. Figure 8 and Figure 9 The first tube 111 is provided with a wire buckle 111g for fixing the cable so that the cable is arranged in a predetermined direction. The second tube 112 is provided with an escape notch 112d for accommodating the wire buckle 111g and the cable.

[0117] In some embodiments, see Figure 2 and Figure 3 The dust cup device 200 is connected and installed on the air duct assembly 100, wherein the dust cup device 200 includes dust cups 210 connected to each other, and the dust cup 210 has a dust collecting cavity 210a.

[0118] Please see further Figure 3 and Figure 6 The second tube body 112 includes a third end face 112e, and the third end face 112e is used to connect the second tube body 112 with the air inlet 200a of the dust cup device 200, so as to realize the communication between the dust collecting chamber 210a and the air inlet channel 110a, and to guide the dust gas from the first tube body 111 to the dust cup device 200.

[0119] In some embodiments, in order to form the air inlet channel 110a, the second tube body 112 is provided with a guide portion 112f. The guide portion 112f is located between the second end surface 112a and the third end surface 112e. The air inlet channel 110a is located in the guide portion 112f.

[0120] See also Figure 11 On the projection plane perpendicular to the first direction R1, the axial direction of the guide portion 112f has an angle α with the second direction R2, satisfying 0°≤α≤90°, for example, α can be an angle of 0°, 30°, 45°, 60° or 90°.

[0121] In some embodiments, on a projection plane perpendicular to the first direction R1, the projection of the central axis of the second tube body 112 forms an angle α with the second direction R2, satisfying 0°<α<90°. For example, α can be 10°, 30°, 45°, 60°, or 80°. This arrangement facilitates the formation of a spiral airflow when dust from the air duct 110 enters the dust cup 210, facilitating cyclonic separation of dust and air.

[0122] It can be understood that, in some embodiments, the angle α is sufficient to allow the dust and gas to enter the dust cup 210 along the tangential direction of the inner wall of the dust cup 210, and the dust and gas can flow circumferentially along the inner wall of the dust cup 210, which is more conducive to forming a spiral airflow.

[0123] In some embodiments, in order to achieve the connection and fixation between the dust cup device 200 and the air duct assembly 100, the air duct assembly 100 includes a first connecting member 120, and the dust cup device 200 includes a second connecting member 220 arranged on the outer wall of the dust cup 210. When the second connecting member 220 is installed on the first connecting member 120, the air inlet 200a is connected to the air inlet channel 110a.

[0124] In some embodiments, see Figure 3 and Figure 12 The first connecting member 120 is set as a connecting groove, and the second connecting member 220 is set as a hook. The second connecting member 220 can extend into the connecting groove from the notch of the connecting groove so that the hook and the connecting groove are engaged with each other, thereby avoiding jamming during the installation of the dust cup device 200 and improving the disassembly and assembly efficiency.

[0125] It should be noted that the first connecting member 120 includes a top wall and a side wall, which together form a connecting groove, and the notch of the connecting groove is directed toward the dust cup device 200 along the first direction R1.

[0126] In some embodiments, the outer edge of the top wall is chamfered to facilitate the hook to be inserted.

[0127] In some embodiments, the air duct 110 and the first connecting member 120 are integrally formed. Furthermore, the side wall is in the shape of a straight surface arranged at an angle, so as to facilitate the integral forming.

[0128] Understandably, see Figure 2 The air duct assembly 100 further includes a tube shell 130 disposed outside the air duct 110 . The tube shell 130 is fixed to the air duct 110 by snap-fitting or threaded connection. The first connector 120 is formed by a portion of the tube shell 130 .

[0129] Specifically, a notch is formed in the upper area of a portion of the housing 130, and the top wall is formed by the portion of the housing wall located around the notch. When the hook is inserted into the connecting groove, part or all of the hook is located in the notch. This arrangement enables the upper housing 130 to support the dust cup assembly 200, while the wall around the notch acts as a limiter for the second connector 220, improving the stability of the dust cup assembly 200. In addition, this arrangement also facilitates the processing and manufacturing of the first connector 120.

[0130] Exemplarily, the second connecting member 220 and the dust cup 210 are integrally formed.

[0131] It should be noted that the cable clip 111 g for fixing the flat cable and the flat cable are both located in the gap between the tube housing 130 and the first tube body 111 .

[0132] In some embodiments, the dust entering the dust cup device 200 through the air inlet 200a is further separated by cyclones through the separation assembly 240. For details, please refer to Figure 14 and Figure 15 One end of the dust cup 210 is provided with an air outlet 210b, and the other end is provided with an openable and closable cylinder cover 230, and the separation component 240 is located in the dust cup 210.

[0133] In some embodiments, see Figures 13 to 17 The separation component 240 includes a first separator 241 and a second separator 242. The first separator 241 is configured to be cylindrical and is provided with a filter cylinder 250, which is used to perform a primary separation of the dust and gas sent into the dust cup device 200 by the second tube body 112; the second separator 242 is located inside the cylindrical first separator 241, and is used to perform a secondary separation of the dust and gas after separation by the first separator 241.

[0134] It is understandable that the entire filter cartridge 250 can be made into a filter, or filter screens can be arranged at intervals on the filter cartridge 250.

[0135] It is also understandable that the filter cartridge 250 can be made of metal or plastic.

[0136] In some embodiments, see Figure 14 and Figure 15 The first dust collecting 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 collecting chamber 210c is connected to the interior of the first separator 241 only through the holes in the filter cylinder 250. Dust entering the dust cup 210 forms a spiral airflow along the inner wall of the first dust collecting chamber 210c, leaving some impurities in the first dust collecting chamber 210c. The filtered air then passes through the filter cylinder 250 and enters the interior of the first separator 241.

[0137] It can be understood that 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 .

[0138] In some embodiments, see Figure 15 A partition plate 243 is provided at the rear end of the first separator 241. The partition plate 243 has at least one third through hole 243a that communicates with the air outlet 210b. A second separator 242 is mounted on the front side of the partition plate 243. The second separator 242 has at least one separation unit 242a. The internal channel formed by the separation unit 242a communicates with the third through hole 243a, allowing the airflow separated by the second separator 242 to flow through the third through hole 243a to the air outlet 210b.

[0139] It is understood that the embodiment of the present application does not limit the number of separation units 242a. For example, the number of separation units 242a is single (eg Figure 30 ), or two, three or more (as shown in Figure 16 、 Figure 32 shown).

[0140] In some embodiments, see 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 spacing space 242e. At least part of the inner tube 2420 extends into the outer tube 2421. An air intake gap 242d is formed at one end of the outer tube 2421 close to the partition 243. The air after the first-level separation flows through the filter cylinder 250 into the spacing space 242e, and enters the separation unit 242a through the air intake gap 242d for secondary separation.

[0141] It is understandable that the partition space 242e and the first dust collecting chamber 210c are connected only through the hole on the filter cylinder 250. Specifically, a sealing plate can be provided to seal 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.

[0142] In some embodiments, see Figure 14 and Figure 15 The part inside the first separator 241 and located in front of the second separator 242 constitutes a second dust collecting chamber 242c, and the second dust collecting chamber 242c is connected to both the outer tube 2421 and the inner tube 2420.

[0143] Understandably, see Figure 15 、 Figure 30 and Figure 32 The inner tube 2420 and the outer tube 2421 are spaced apart to form a channel 242b, and the air flow passes through the air inlet gap 242d and enters the channel 242b for secondary separation.

[0144] It is understood that in some embodiments, see Figure 30 and Figure 32 The inner tube 2420 can be set as an integral structural part with the partition 243. For example, the inner tube 2420 is formed by stamping the partition 243. In some 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, etc.

[0145] It should be noted that, in some embodiments, please refer to 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.

[0146] It is also understood that in some embodiments, see Figure 15 The outer tube 2421 is spaced apart from the partition plate 243 along its axial direction at one end thereof close to the partition plate 243, thereby forming an air intake gap 242d.

[0147] In some embodiments, see Figure 30 and Figure 32 The outer tube 2421 is connected to the partition 243. An opening extending along the axis of the outer tube 2421 is formed on the wall of the outer tube 2421 near the partition 243. This opening forms the air inlet gap 242d. It will be appreciated that the length of the air inlet gap 242d extending along the axis of the outer tube 2421 can be appropriately selected based on the volume of the first separator 241.

[0148] In some embodiments, see Figure 14 and Figure 15 The separation unit 242a further includes a dust outlet 244 , which is connected to one end of the outer tube 2421 away from the inner tube 2420 , and the inner diameter of the dust outlet 244 gradually decreases in a direction away from the outer tube 2421 .

[0149] In the solution of the embodiment of the present application, the dust outlet portion 244 is roughly conical in structure, which can accelerate the rotation of the airflow, thereby making the dust falling more efficient.

[0150] It is understandable that the embodiments of the present application do not limit the shape of the dust outlet portion 244. For example, the shape of the dust outlet portion 244 is approximately conical.

[0151] In some embodiments, see Figure 30 The dust outlet end of the dust outlet portion 244 is provided with a baffle 244a, and a dust outlet port 244c is formed between the baffle 244a and the peripheral wall of the dust outlet portion 244, so that dust is discharged along the radial direction of the dust outlet portion 244 and falls into the second dust collecting chamber 242c. This configuration can improve the efficiency of dust-gas separation and avoid unsatisfactory dust-gas separation when the dust outlet port of the dust outlet portion 244 is large. For example, when only a small number of separation units 242a (e.g., one or two) are provided.

[0152] In some embodiments, see Figure 30 The baffle 244a is connected to the peripheral wall of the dust outlet portion 244 via two or more connecting ribs 244b, and dust outlet ports 244c are formed between adjacent connecting ribs 244b.

[0153] In order to make the airflow form a cyclone in the separation unit 242, the following solution may be adopted.

[0154] In some embodiments, for the solution of forming the air intake gap 242d by spacing the outer tube 2421 and the partition 243, please refer to Figure 15 A guide structure 2422 for guiding the airflow is provided in the channel 242b, so that the airflow in the channel 242b forms a cyclone, thereby improving the separation effect.

[0155] For details, please refer to Figure 3 、 Figure 15 and Figure 17The flow-guiding structure 2422 is a guide blade connected between the inner tube 2420 and the outer tube 2421. The guide blade extends axially along the outer tube 2421 and spirally surrounds the inner tube 2420. The flow-guiding structure 2422 guides the airflow in a circumferential direction within the channel 242b, causing the airflow to rotate within the channel 242b. Dust and impurities entrained in the airflow are separated from the airflow by centrifugal force and settle into the second dust collection chamber 242c. The separated air then flows along the inner tube 2420 toward the air outlet 210b under the action of negative pressure.

[0156] In some other embodiments, see Figure 16 The flow guiding structure 2422 includes three guide blades arranged along the circumference of the outer tube 2421. The three guide blades are arranged in a spiral shape around the inner tube 2420, and adjacent guide blades are spaced apart. For example, the guide blades can be evenly distributed along the circumference of the outer tube 2421. Each guide blade guides the flow along the circumference of the channel 242b, causing the airflow entering the outer tube 2421 to generate a cyclone therein, thereby separating dust carried in the airflow.

[0157] It should be noted that the number of guide blades in the embodiments of the present application is not limited to one or three, and may also be two, four or more, and the specific selection can be made according to actual application requirements.

[0158] For some examples, see Figure 17 Along the axial direction of the inner tube 2420 , the end of the guide plate away from the air intake gap 242d is set to be a straight section, and the straight section is parallel to the cross section of the inner tube 2420 .

[0159] Among them, the upper end of the channel 242b is the inlet, and along the air inlet 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 along 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.

[0160] It is understood that the embodiment of the present application does not limit the shape of the guide piece. Exemplarily, the shape of the guide piece is a straight plate.

[0161] In some embodiments, the guide plate is integrally formed with the inner tube 2420 and the outer tube 2421 .

[0162] In the solution of the embodiment of the present application, the guide piece, the inner tube 2420 and the outer tube 2421 are an integrally formed structure, so that the overall strength of the separation unit 242a is higher.

[0163] It is understood that the embodiments of the present application are not limited to the guide piece being an integrally formed structure with the inner tube 2420 and the outer tube 2421. For example, the guide piece, the inner tube 2420 and the outer tube 2421 can be manufactured separately and then assembled into one body.

[0164] In some embodiments, the wall 2421 of the outer tube 2421 is opened to form the air inlet gap 242d. Figure 30 and Figure 32 The end of the outer tube 2421 close to the partition 243 is the first tube section.

[0165] In some embodiments, see Figure 32 The tube wall of the first tube section includes at least one second tube wall 2421c. Along the circumference of the outer tube 2421, the distance between one end of the second tube wall 2421c and the axis of the outer tube 2421 is smaller than the distance between the other end of the second tube wall 2421c and the axis of the outer tube 2421, thereby forming the air intake gap 242d at one end and / or the other end of the second tube wall 2421c. This arrangement enables the airflow to form a vortex along the circumference of the second tube wall 2421c.

[0166] For details, please refer to Figure 32 The tube wall of the first tube section includes a plurality of second tube walls 2421c, which are distributed along the circumference of the outer tube 2421. An air intake gap 242d is formed between the ends of adjacent second tube walls 2421c. The above arrangement can improve the air intake efficiency.

[0167] In some embodiments, see Figure 30 The first tube section includes a first tube wall 2421b and a second tube wall 2421c. One circumferential end of the first tube wall 2421b is connected to one circumferential end of the second tube wall 2421c. The other circumferential ends of the first tube wall 2421b and the other circumferential ends of the second tube wall 2421c are separated to form an air intake gap 242d. From the connecting end of the second tube wall 2421c and the first tube wall 2421b to the free end of the second tube wall 2421c, the distance between the second tube wall 2421c and the axis of the outer tube 2421 gradually increases. This arrangement enables airflow to form a vortex along the circumference of the second tube wall 2421c and the first tube wall 2421b.

[0168] In some embodiments, see Figures 30 to 32 The connection between the first tube wall 2421b and the second tube wall 2421c is smoothly transitioned.

[0169] In some embodiments, see Figures 30 to 32The diameter of the circle where the cross section of the first tube wall 2421b lies is smaller than the diameter of the circle where the cross section of the second tube wall 2421c lies, and the connecting portion of the first tube wall 2421b and the second tube wall 2421c is tangentially connected.

[0170] In some embodiments, see Figures 30 to 32 The second tube wall 2421c and the first tube wall 2421b are connected to each other via an end plate 2421a at one end of the outer tube 2421 away from the partition plate 243 in the axial direction.

[0171] Understandably, see Figure 30 A plurality of first tube walls 2421b and a plurality of second tube walls 2421c are formed along the circumference of the outer tube 2421. For example, when only a small number of separation units 242a (such as 1, 2, etc.) are set, this arrangement can form a plurality of air intake gaps 242d to improve the dust and gas separation efficiency.

[0172] It is understandable that the entire outer tube 2421 can be set as the first tube section. In this case, an air intake gap 242d is formed on the outer tube 2421 along its axial direction.

[0173] In some embodiments, see Figure 30 The filter cylinder 250 of the first separator 241 is connected to the second cylinder 270 at one end facing the cylinder cover 230. The second cylinder 270 is sealed to the cylinder cover 230. The average inner diameter of the filter cylinder 250 is larger than the average inner diameter of the second cylinder 270. The above arrangement can increase the overall volume of the first dust collecting chamber 210c.

[0174] 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 tapered cylinder or an arc-conical cylinder to improve the smoothness of the air flow. In some embodiments, the transition section 280 is configured as an annular plate 280a, such as Figure 30 As shown, the annular plate 280a can simultaneously block the end of the filter cartridge 250 facing the cartridge cover 230 and the outer tube 2421 to form a sealing plate.

[0175] It is understood that in some embodiments, see Figure 14 and Figure 15 The end of the filter screen 250 of the first separator 241 facing the cylinder cover 230 is connected to the first cylinder 260 , 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 .

[0176] It is understandable that, at this time, the second cylinder 270 is provided with a transition section 280 connected to the first cylinder 260 to achieve 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.

[0177] In some embodiments, see Figure 14 and Figure 15 The transition section 280 is provided with a retaining cylinder 260a at one end away from the cylinder cover 230. The retaining cylinder 260a is spaced apart from the second cylinder 270. When the cleaning device is in operation, the retaining cylinder 260a can suppress dust in the first dust collecting chamber 210c. When the airflow sweeps up dust and debris in the first dust collecting chamber 210c, some of the dust will be blocked by the retaining cylinder 260a, thereby reducing dust backflow.

[0178] It is understandable that there may be no vent holes or multiple vent holes on the blocking cylinder 260a. When multiple vent holes are provided, it is beneficial for the cleaning equipment to be in operation. When the dust and gas rolled up in the first dust collecting chamber 210c reaches the blocking cylinder 260a, the air flow is allowed to pass through the vent holes, thereby reducing the turbulence caused by the obstruction of the blocking cylinder 260a.

[0179] In some embodiments, the inner diameter of the retaining cylinder 260a is larger than the inner diameter of the filter cylinder 250, which can improve the dust blocking capability and further reduce dust recirculation.

[0180] In some other embodiments, see Figure 14 and Figure 15 The inner diameters of the filter cylinder 250, the first cylinder 260 (it can be understood that in some embodiments, the first cylinder 260 may not be provided) and the retaining cylinder 260a gradually decrease along the axial direction close to the cylinder cover, thereby increasing the volume of the first dust collecting chamber 210c; in addition, due to the rotating airflow generated in the dust cup 210, the above-mentioned arrangement gradually increases the cross-sectional area of the first dust collecting chamber 210c in the axial direction close to the cylinder cover, which can gradually weaken the airflow intensity, making it easier for dust to be deposited in the first dust collecting chamber 210c near the cylinder cover 230. At the same time, due to the weak airflow intensity, the amount of dust raised is reduced.

[0181] In some embodiments, see Figure 14 and Figure 15 The dust cup assembly 200 has a negative pressure chamber 200b behind the partition 243. After two stages of dust and gas separation, the airflow enters the negative pressure chamber 200b through the third through-hole 243a and, under the action of negative pressure, flows further toward the fan assembly 300. A low-pressure buffer zone is easily formed within the negative pressure chamber 200b, improving dust collection efficiency.

[0182] It is understood that in some embodiments, see Figure 30The peripheral wall, partition 243 and inner tube 2420 of the negative pressure chamber 200b are set as an integral structural part. 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.

[0183] In some embodiments, see 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.

[0184] It is understandable that a sealing ring may be provided around the motor pre-filter 291 to improve the sealing performance and enhance the negative pressure efficiency.

[0185] It can also be understood that the motor pre-filter 291 can be made of filter cotton, filter and other materials; in some embodiments, the motor pre-filter 291 can fill the negative pressure chamber 200b.

[0186] In some embodiments, see 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 connecting member 290 connected to the dust cup 210, and the fan assembly 300 is provided with a fourth connecting member 330. The third connecting member 290 cooperates with the fourth connecting member 330 to realize the detachable installation of the dust cup device 200 and the fan assembly 300.

[0187] In some embodiments, see Figure 3 The third connecting member 290 is located at the top of the rear end of the dust cup 210, and the fourth connecting member 330 is located at the top of the front end of the fan assembly 300. This arrangement can facilitate the user to disassemble and assemble the dust cup device 200.

[0188] It is understandable that the third connecting member 290 and the dust cup 210 can be configured to be integrally formed.

[0189] In the solution of the embodiment of the present application, the dust cup device 200 is connected and assembled with the air duct assembly 100 through the first connecting member 120 and the second connecting member 220, and is connected and assembled with the fan assembly 300 through the third connecting member 290 and the fourth connecting member 330, thereby further improving the installation stability of the dust cup device 200.

[0190] In some embodiments, see Figure 19 and Figure 20The fourth connecting member 330 has a locked state and an unlocked state, that is, when the fourth connecting member 330 is in the locked state, the fourth connecting member 330 can lock the third connecting member 290 to avoid the emergency situation that the dust cup device 200 accidentally separates from the fan assembly 300 during operation. When the fourth connecting member 330 is in the unlocked state, the fourth connecting member 330 and the third connecting member 290 are separated from each other.

[0191] Exemplarily, the fourth connecting member 330 can rotate relative to the third connecting member 290 to achieve switching between an unlocked state and a locked state. For example, the fourth connecting member 330 is connected to the fan assembly 300 through a rotating shaft 420, and the axial direction of the rotating shaft 420 is perpendicular to the first direction R1 and the second direction R2 at the same time to achieve the rotation of the fourth connecting member 330; or the connection between the fourth connecting member 330 and the fan assembly 300 can undergo elastic deformation to achieve the rotation of the fourth connecting member 330.

[0192] For example, please see Figure 20 The fourth connecting member 330 is formed with a locking groove 330a, and the third connecting member 290 protrudes upward to form a bump 290a. When the fourth connecting member 330 locks the third connecting member 290, the bump 290a is at least partially located in the locking groove 330a.

[0193] In the embodiment of the present application, the locking groove 330a cooperates with the protrusion 290a to limit the axial and circumferential movement of the dust cup device 200, thereby further increasing the stability of the dust cup device 200. Furthermore, the protrusion 290a of the third connecting member 290 only needs to be raised a small height to achieve locking engagement with the locking groove 330a, making the overall structure of the dust cup device 200 relatively flat and convenient for packaging.

[0194] It is understandable that, in some embodiments, at least a portion of the fourth connecting member 330 forming the locking groove 330 a can be elastically deformed, thereby achieving an interference fit connection between the fourth connecting member 330 and the third connecting member 290 .

[0195] For example, at least a portion of the fourth connecting member 330 forming the locking groove 330 a is made of an elastic material. Specifically, the elastic material includes rubber, elastomeric plastic, elastic foam material, elastic textile, etc.

[0196] In some embodiments, see Figure 20 A snap-fitting groove 290b is formed on the side of the third connecting member 290 facing the negative pressure chamber 200b, and the mounting end cover 340 of the fan assembly 300 protrudes upward in its radial direction to form a snap-fitting protrusion 340a. When the hook and the connecting groove are snapped together, the snap-fitting protrusion 340a is at least partially located in the snap-fitting groove 290b.

[0197] In the embodiment of the present application, the third connecting member 290 can cooperate with the snap-fit groove 290b and the snap-fit protrusion 340a to fix the third connecting member 290 relative to the fan assembly 300, thereby increasing the connection strength between the dust cup 210 and the fan assembly 300.

[0198] Exemplarily, the locking groove 290 b and the protrusion 290 a are respectively located on opposite sides of the third connecting member 290 along the up-down direction.

[0199] It should be noted that the embodiment of the present application does not limit whether the third connecting member 290 is formed with a locking groove 290 b.

[0200] It is understood that in some embodiments, see Figure 20 A sealing ring 320 is also provided on the rear side of the mounting end cover 340 to improve the sealing effect.

[0201] In some embodiments, see Figure 21 The fourth connector 330 includes a connector head 331, a connector handle 332, and a stop plate 333. A locking groove 330a is provided on the connector head 331. The connector handle 332 is used to connect to the fan assembly 300. The stop plate 333 is provided between the connector head 331 and the connector handle 332 and extends downward in the first direction R1. The locking groove 330a is located on the side of the stop plate 333 away from the connector handle 332. When the locking groove 330a is engaged with the protrusion 290a, the stop plate 333 can abut against the mounting end cap 340 of the fan assembly 300, providing support for the fourth connector 330 and improving assembly strength.

[0202] It should be noted that flat-bottomed grooves 340b are provided at corresponding positions of the mounting end cover 340 and the limiting plate 333 of the fan assembly 300 to increase the contact area between the bottom of the limiting plate 333 and the mounting end cover 340 and improve the support stability.

[0203] Understandably, see Figure 21 The flat-bottomed groove 340b is located on the rear side of the snap-fitting protrusion 340a. When the third connecting member 290 and the fourth connecting member 330 are in the locked state, the protrusion 290a is located in the space enclosed by the snap-fitting protrusion 340a, the locking groove 330a and the limiting plate 333, thereby making the locking strength higher.

[0204] It is understandable that the fourth connection member 330 and the third connection member 290 can also be locked and unlocked in other ways. For example, the fourth connection member 81 and the third connection member 290 can be configured as a pin and slot matching form.

[0205] In some embodiments, see Figure 21Two support handles 334 are connected to both sides of the connecting handle 332 of the fourth connecting member 330. The support handles 334 are clamped on the fan assembly 300. The fourth connecting member 330 also includes an elastic member 335. The elastic member 335 contacts the support handle 334 to apply a thrust to the support handle 334. The thrust is used to automatically restore the fourth connecting member 330 from an unlocked state to a locked state to achieve automatic reset.

[0206] It is understandable that more than two elastic members 335 may be provided to respectively abut against the two support handles 334 .

[0207] Understandably, see Figure 21 A spring mounting position 337 is provided at the corresponding position of the support handle 334.

[0208] It can be understood that the elastic member 335 is configured as an axial compression spring. When the fourth connecting member 330 is in a locked state, the compression force applied to the compression spring is greater than or equal to 0 Newton. When the fourth connecting member 330 changes from a locked state to an unlocked state, the compression force applied to the compression spring will gradually increase.

[0209] In some embodiments, see Figure 21 The free ends of the two support handles 334 are each provided with an end shaft 336 , and the end shaft 336 is rotatably provided. It can be understood that the free end of at least one support handle 334 only needs to be provided with an end shaft 336 .

[0210] It can also be understood that the present application does not limit the type of the elastic member 335 , and the elastic member 335 can also be a torsion spring.

[0211] It can also be understood that the embodiments of the present application do not limit whether the fan assembly 300 is provided with the elastic member 335 .

[0212] In some embodiments, see Figure 20 The third connecting member 290 has a first abutting surface 290c, and the fourth connecting member 330 has a second abutting surface 330b. During the installation of the dust cup device 200, the first abutting surface 290c can exert a thrust on the second abutting surface 330b, thereby pushing the fourth connecting member 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 realize the fourth connecting member 330 from the locked state to the unlocked state, saving time and effort and providing a better user experience.

[0213] It should be noted that in the above embodiments, please refer to Figure 20In the process of locking the fourth connecting member 330 to the third connecting member 290, the user does not directly apply a force to the fourth connecting member 330. Instead, the user applies a force to the third connecting member 290, thereby indirectly pushing the fourth connecting member 330 to rotate relative to the fan body, thereby unlocking the fourth connecting member 330. It is understood that in the above process, the user can also directly apply a force to the fourth connecting member 330, causing the fourth connecting member 330 to rotate relative to the fan body, thereby unlocking the fourth connecting member 330.

[0214] Therefore, the above two installation methods are both within the protection scope of this application.

[0215] It is understandable that the rear end face of the dust cup device 200 and the front end face of the fan assembly 300 are both inclined to form 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; and the distance between the front end face of the fan assembly 300 and the cylinder cover gradually decreases from top to bottom. This arrangement can avoid 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 from top to bottom on the fan assembly 300. After installation, the installation gap between the two end faces can be minimized, thereby improving assembly accuracy.

[0216] The following is a complete description of the installation and removal process of the dust cup device 200 in combination with the above structure:

[0217] During installation, first extend the second connecting member 220 into the first connecting member 120 from the slot of the first connecting member 120 , and preliminarily install the front section of the dust cup device 200 on the upper side of the air duct assembly 100 .

[0218] Then, the rear section of the dust cup device 200 is rotated downward with the second connecting member 220 as the axis, so that the first abutting surface 290c abuts the second abutting surface 330b. Continue to apply downward pressure to the rear section of the dust cup device 200, so that the third connecting member 290 pushes the fourth connecting member 330 to rotate. When the dust cup device 200 is installed in place, the fourth connecting member 330 automatically locks the third connecting member 290 under the action of the elastic member 335. Alternatively, the user can manually rotate the fourth connecting member 330 to open a certain angle between the fourth connecting member 330 and the fan assembly 300, and then rotate the other end of the dust cup device 200 downward with the second connecting member 220 as the rotation center to install the dust cup device 200 in place. The user then releases the fourth connecting member 330, causing the fourth connecting member 330 to return to its original position and lock the third connecting member 290.

[0219] When disassembling, the user can manually rotate the fourth connecting member 330 to unlock the fourth connecting member 330. Then, the user holds the dust cup device 200 and rotates it upward with the second connecting member 220 as the rotation center until the second connecting member 220 is disengaged from the notch of the first connecting member 120.

[0220] For example, see Figure 3 Along the axial direction of the dust cup assembly 200 (i.e., the first direction R1), the distance between the third connecting member 290 and the second connecting member 220 is greater than or equal to half the length of the dust cup 210. This configuration allows the restraining force between the air duct assembly 100 and the fan assembly 300 and the dust cup assembly 200 to be distributed on opposite sides of the dust cup 210, reducing the length of the free end of the dust cup assembly 200 and thus preventing the dust cup assembly 200 from shaking during use.

[0221] In some embodiments, see Figure 19 The fan assembly 300 includes a main shell 350, which is provided with an installation cavity 350a for installing the motor 360 and the impeller. The installation cavity 350a is connected to the negative pressure chamber 200b of the dust cup device 200; one end of the main shell 350 is connected to the dust cup device 200.

[0222] It can be understood that, in some embodiments, the fourth connecting member 330 is installed on the main housing 350 .

[0223] It should be noted that during the use of the cleaning equipment, static electricity will be generated by the friction between the roller brush of the floor brush and the floor or carpet, and the dust rotating and rubbing in the connecting pipe and the dust cup 210 will also generate static electricity. If the static electricity is not released in time, the electricity will accumulate and be released through tip discharge after a certain amount. When the user operates the vacuum cleaner, the tip discharge will make the user feel like 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. The aluminum foil is easy to cause the anti-static wire to fall off after a long time of use; 2. The dust cup 210 is injection molded with anti-static material, but its cost is relatively high; 3. A protruding structure is set on the dust cup 210 for arranging the electrostatic sheet 370, but the aesthetics is poor.

[0224] In some embodiments, see Figure 22 、 Figure 23 and Figure 28 The motor 360 has a conductive motor housing 360a, such as a motor housing 360a made of metal. A vibration reduction structure 360b for reducing shock and noise is provided on the outside of the motor housing 360a. An electrostatic sheet 370 is arranged between the motor housing 360a and the vibration reduction structure 360b. The electrostatic sheet 370 is clamped and fixed by the motor housing 360a and the vibration reduction structure 360b.

[0225] It is understandable that the electrostatic sheet 370 is connected to the electrostatic release sheet 370a via 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.

[0226] In some embodiments, see 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 blower assembly 300 is located at the front end of the axial direction of the motor 360, and the connection between the support member 510 and the blower assembly 300 is located at the rear end of the axial direction of the motor 360. This arrangement improves the support stability of the cleaning device provided by the handle 500 and the support member 510. When the cleaning device is provided with the support member 510, the static discharge sheet 370a can be fixed to the support member 510.

[0227] It should be noted that when the static electricity release sheet 370 a is fixed to the handle 500 or the support member 510 , the static electricity release sheet 370 a is exposed through the hollow portion of the handle 500 or the support member 510 .

[0228] It should also be noted that, in some embodiments, the support member 510 is located on the rear side 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, and during use, the support member 510 can also assist the handle 500 in playing a certain gripping role.

[0229] It should be noted that the support member 510 is inclined from top to bottom toward the rear.

[0230] It is understood that the conductive structure 370d can be a conductive wire, one end of which is fixed to the electrostatic sheet 370 by welding, and the other end of which is fixed to the electrostatic release sheet 370a by welding. In addition to welding, the electrical connection between the conductive structure and the electrostatic sheet 370 and the electrostatic release sheet 370a can also be achieved by riveting, screwing, etc.

[0231] In this embodiment, after the electrostatic sheet 370 is installed, static electricity from various locations will continue to be transmitted to the user's hand through the electrostatic sheet 370, the wiring harness, and the electrostatic release sheet 370a before it accumulates, and can be transmitted to the ground through the human body. This avoids static electricity accumulation leading to concentrated discharge, which affects the user experience.

[0232] It is understood that in some embodiments, see Figure 23The electrostatic sheet 370 includes a base sheet 370b and an elastic sheet 370c. In its original state, the elastic sheet 370c is able to rise from the base sheet 370b. When subjected to external force, the elastic sheet 370c is pressed toward the base sheet 370b. This arrangement further increases the friction between the electrostatic sheet 370, the motor housing 360a, and the rubber ring vibration damping structure 360b, making the electrostatic sheet 370 less likely to fall off and improving the conductivity.

[0233] It is understood that the original state refers to the state of the electrostatic sheet 370 when it is not installed in the fan assembly 300. It is also understood that after the electrostatic sheet 370 is installed in the fan assembly 300, the elastic restoring force of the elastic sheet 370c will deteriorate due to prolonged compression by the motor housing 360a and the vibration reduction structure 360b. After the electrostatic sheet 370 is removed, the elastic sheet 370c may not be noticeably lifted from the base sheet 370b. However, those skilled in the art will understand that it can lift from the base sheet 370b in the original state.

[0234] In some embodiments, see Figure 23 The base sheet 370b and the elastic sheet 370c are an integrated structural component, for example, the elastic sheet 370c is punched out from a base sheet 370b.

[0235] In some embodiments, see Figure 19 and Figure 28 The fan assembly 300 includes a housing 300a, the motor 360 and the wind wheel are both located in the housing 300a, and the vibration reduction structure 360b is located in the housing 300a.

[0236] It should be noted that the front side of the housing 300a is provided with an air inlet grille 300b, through which the airflow separated and filtered by the dust cup device 200 enters the housing 300a. The rear shell of the housing 300a is provided with an air outlet, through which the airflow in the housing 300a can enter the installation cavity 350a.

[0237] In some embodiments, see Figure 19 Along the first direction R1, the accommodating shell 300a together with the motor 360 is located on the side of the mounting bracket 390 away from the cover device 400, the air outlet shell 380 is located on the side of the mounting bracket 390 facing the cover device 400 and extends into an accommodating cavity 380b, and an air outlet chamber 390a is formed between the air outlet shell 380 and the mounting bracket 390. A first through hole 380a connecting the air outlet chamber 390a and the accommodating cavity 380b is formed on the air outlet shell 380.

[0238] Understandably, see Figure 19The mounting bracket 390 is provided with a connecting hole to connect the mounting cavity 350a with the air outlet chamber 390a.

[0239] In some embodiments, see Figure 19 The air outlet housing 380 is provided with a first through hole 380a communicating with the outside to discharge the airflow to the outside.

[0240] In some embodiments, see Figure 25 The accommodating cavity 380b is used to accommodate 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 is a structure capable of absorbing fine dust in the air flow.

[0241] In some embodiments, the filter element 800 is a Hypa filter 250 or a sponge.

[0242] It is understood that the embodiments of the present application do not limit the type of the filter element 800 .

[0243] It can be understood that the filter element 800 is detachably disposed in the accommodating cavity 380 b so that the user can easily replace the filter element 800 .

[0244] It is understandable that the filter element 800 can be configured to have an aromatherapy function. In addition to filtering the airflow, different aromatherapy scents can be selected according to the user's personal preferences.

[0245] It should be noted that the aromatherapy function can be specially configured as a module placed in the accommodating cavity 380b and separated from the filter element 800.

[0246] It is understandable that the filter element 800 can be arranged around the air outlet housing 380, or 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 to further improve the dust removal capability.

[0247] In the embodiment of the present application, the filter element 800 is annular and can be well covered around the air outlet housing 380, so that the air flow from the air outlet chamber 390a to the outside passes through the filter element 800, thereby improving the filtering effect.

[0248] It is understood that the embodiments of the present application do not limit the shape of the filter element 800 .

[0249] It can be understood that the main shell 350 of the embodiment of the present application can be set as an integrated structure or a split structure. When the main shell 350 is set as a split structure, the shell of the accommodating cavity 380b can be formed separately by a part of the main shell 350, thereby facilitating processing and manufacturing.

[0250] In some embodiments, see Figure 19 、 Figures 25 to 27 A cover device 400 is provided at the rear end of the fan assembly 300. The cover device 400 is movably mounted on the main housing 350 to cover the opening 380c of the accommodating cavity 380b.

[0251] In some embodiments, see Figure 25 and Figure 27 The cover assembly 400 has a first state and a second state. When the cover assembly 400 is in the first state, the cover assembly 400 closes the opening 380c. When the cover assembly 400 is in the second state, the cover assembly 400 opens the opening 380c. The filter element 800 can be moved into or out of the accommodating chamber 380b through the opening 380c.

[0252] In some embodiments, see Figure 19 、 Figure 28 and Figure 29 The display assembly 900 is mounted on the cover device 400 and is located on the side of the cover device 400 that is away from the accommodating cavity 380b. It should be noted that the display assembly 900 is a structure that can display the current status of the cleaning device.

[0253] Exemplarily, the current state of the cleaning device includes the remaining power of the cleaning device, the cleaning mode, and the on / off state, etc. In some embodiments, the display component 900 can display multiple current states of the cleaning device, and the user can more intuitively understand the current state of the cleaning device.

[0254] In the embodiment of the present application, the display assembly 900 is mounted on the cover assembly 400, and is located on the side of the cover assembly 400 facing away from the accommodating cavity 380b. This allows the user to clearly see the current status of the cleaning device during use. In the prior art, when the display assembly 900 is not on the cover assembly 400, for example, on the side of the main housing 350, the user must turn sideways each time to check, and may even need to pause their work before checking, which is inconvenient.

[0255] It can be understood that in order to improve the filtering effect, the filter element 800 fills the entire accommodating cavity 380b. When the display component 900 is set on one side of the main shell 350, it will occupy the circumferential space of the accommodating cavity 380b, thereby reducing the setting space of the filter element 800, thereby affecting the filtering effect.

[0256] In some embodiments, see 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 more conveniently observe the display component 900 while holding the handle 500, which alleviates the obstruction of the user's vision by the user's arm, and the user experience is better.

[0257] In some embodiments, the display assembly 900 further has control buttons.

[0258] It is understandable that the control button includes a physical button or a touch-sensitive button. This arrangement can facilitate the user to operate and control the cleaning device.

[0259] In some embodiments, the display component 900 is an electronic display screen.

[0260] Exemplarily, the electronic display screen is a color display screen.

[0261] Exemplarily, the electronic display screen is a touch screen, and the user can switch the cleaning function of the cleaning device by touching the electronic display screen.

[0262] It is understood that the embodiments of the present application do not limit the type of display screen. For example, the display screen includes a plurality of display lights, the plurality of display lights are arranged at intervals, and the color of each display light is different.

[0263] Exemplarily, along the axial projection of the accommodating cavity 380 b , the projection area of the display assembly 900 is substantially circular.

[0264] In the embodiment of the present application, the display assembly 900 can make full use of the surface of the cover device 400 on the side away from the accommodating cavity 380b along the axial direction of the accommodating cavity 380b, and the display screen can be as large as possible, so that the user can observe the display screen more clearly.

[0265] In some embodiments, along the axial projection of the cover device 400, the projection area of the display assembly 900 overlaps with the projection area of the cover device 400. It is understood that in the embodiments of the present application, the projection area of the display assembly 900 overlaps with the projection area of the cover device 400, including the case where the projection area of the display assembly 900 is smaller than the projection area of the cover 410 body and is located therebetween.

[0266] In some embodiments, see Figure 25 The cover device 400 is rotatably mounted on the main housing 350 .

[0267] It is understandable that rotating the cover device 400 by applying an external force can switch the cover device 400 between the first state and the second state, making it easier to replace the filter element 800 and providing a better user experience.

[0268] It is understood that the embodiments of the present application are not limited to the cover device 400 being rotatably mounted on the main housing 350. For example, the cover device 400 and the main housing 350 are configured to have mutually cooperating slide grooves and sliders, and the cover device 400 can be moved relative to the main housing 350 by moving the slider. When the cover device 400 moves away from the main housing 350, the cover device 400 switches from the first state to the second state.

[0269] In some embodiments, see Figure 19 、 Figure 24 and Figure 25 The cover device 400 includes a cover 410, a rotating shaft 420, and a connecting member 430 connecting the cover 410 and the rotating shaft 420. The cover 410 can be rotated and opened by the rotating shaft 420, and the display component 900 is set on the cover 410.

[0270] It is understandable that the rotating shaft 420 can be provided on the fan assembly 300 or the handle 500 .

[0271] In some embodiments, see Figure 24 The connector 430 has a cable cavity 430a, which is used to accommodate the power supply line 610 to electrically connect the power supply line 610 to the display component 900. On the one hand, the connector 430 provides protection for the cable, which is safe and reliable. On the other hand, it avoids exposing the cable, making the cleaning device simple and beautiful.

[0272] Exemplarily, the rotating shaft 420 is connected to the end of the connecting member 430 facing away from the cover plate 410 .

[0273] In the embodiment of the present application, the rotating shaft 420 is as far away from the cover plate 410 as possible to 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 accommodating cavity 380b and reducing the interference of the cover plate 410 on the filter element 800.

[0274] For example, see Figure 24 and Figure 25 The sidewall of the accommodating chamber 380b is provided with a cover structure 380d, which is provided with a third opening 380e for the connector 430 to pass through. The connector 430 comprises a connected arcuate segment 430b and a straight segment 430c. The arcuate segment 430b passes through the third opening 380e, and the rotating shaft 420 is connected to the end of the straight segment 430c that is distal from the arcuate segment 430b. This arrangement helps reduce the interference range of the connector 430 during the rotation of the cover assembly 400, minimizes the size of the third opening 380e, and improves the sealing performance of the accommodating chamber 380b.

[0275] It is understandable that when the cover structure 380d is provided on the side wall of the accommodating cavity 380b, the annular filter element 800 is provided with a gap to avoid the cover structure 380d.

[0276] Exemplarily, the rotation center axis of the rotating shaft 420 is arranged crosswise with the axis of the main housing 350 of the fan assembly 300, for example, arranged perpendicular to each other. It can be understood that the cover plate 410 can be flipped upward or downward.

[0277] For example, see Figure 19 The rotation center axis of the rotating shaft 420 is arranged along the third direction R3, and the third direction R3 is perpendicular to both the first direction R1 and the second direction R2.

[0278] For example, the rotation center axis of the rotating shaft 420 may be arranged along the first direction R1, and the cover device 400 may be rotated sideways to open the opening 380c, that is, the cover device 400 rotates around the first direction.

[0279] It is understandable that, according to actual needs, the rotation center axis of the shaft 420 can be arranged in other directions, for example, arranged on one side of the main shell 350 along the second direction R2, and the cover device 400 can be flipped open from the left or right side.

[0280] In some embodiments, see Figure 25 and Figure 26 The cover device 400 also includes a first fixing member 440, which is movably arranged on the cover 410. A second fixing member 310 is arranged on the main shell 350 of the fan assembly 300. When the cover 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 device 400, so that the cover device 400 can be maintained in the first state more stably.

[0281] In some embodiments, see Figure 25 The first fixing member 440 is configured 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 arranged around the display component 900, and can rotate around the display component 900 by a predetermined angle, and a locking protrusion 442a is provided on the locking ring; the second fixing member 310 is configured as a card slot on the main shell 350, and the locking and unlocking of the cover plate device 400 and the main shell 350 are achieved by rotating the locking ring and cooperating with the card slot of the card protrusion 442a.

[0282] It is understandable that the locking ring can rotate around the display assembly 900 , but is still limited on the cover plate 410 to prevent the locking ring from automatically falling off the cover plate 410 .

[0283] In some embodiments, see Figure 25 The locking ring includes an inner ring 442 and an outer ring 441. The outer ring 441 is used for the user to hold and operate. A locking protrusion 442a is set on the outer wall of the inner ring 442, and a locking groove is set on the inner wall of the main shell 350.

[0284] It is understandable that the protrusion 442a can be configured in various shapes, such as Figure 25 The long strip shape shown can also be set to a cylindrical shape.

[0285] In some embodiments, see Figure 25 In order to avoid the connecting member 430, an avoidance opening 440a is provided on the locking ring. It can be understood that in order to avoid interference between the locking ring and the connecting member 430 when rotating, the width of the avoidance opening 440a is greater than the width of the connecting member 430.

[0286] It is understandable that the embodiments of the present application do not limit whether the first fixing member 440 surrounds the circumference of the cover plate 410 and is capable of rotating relative to the cover plate 410 .

[0287] In some embodiments, a heat dissipation hole (not shown in the figure) may be provided on the side of the cover plate 410 facing the accommodating cavity 380 b , and the heat dissipation hole may be used to improve the heat dissipation effect of the display assembly 900 .

[0288] In some embodiments, see Figure 1 and Figures 27 to 29 The cleaning device has a handle 500 , which is connected to the lower sides of the fan assembly 300 and the cover device 400 .

[0289] For example, see Figure 27 In order to facilitate the user to hold the handle 500 when using it, the handle 500 is configured to be curved in an arc shape.

[0290] See also Figure 29 Specifically, in the embodiment of the present application, the center line P2 of the handle 500 is curved into an arc shape. In some embodiments, the center line P2 of the handle 500 is an arc line, and the center of the circle where the arc line is located is located in front of the handle 500. The extension line P3 of the circle where the arc line is located does not intersect with the axis O of the motor 360, that is, the circle where the arc line is located is separated from the axis of the motor 360, so as to improve the grip effect of the cleaning device. The center line of the handle 500 is roughly an arc line.

[0291] It should be noted that the axis O of the main shell 350 and the axis of the dust cup device 200 can be set to coincide or not coincide.

[0292] In some embodiments, see Figure 28 and Figure 29The handle 500 is provided with a first side surface 500 a and a second side surface 500 b facing each other. The first side surface 500 a is located at the rear side of the handle 500 and is configured as a curved surface.

[0293] In some examples, the first side surface 500a and the second side surface 500b may both be configured as arc surfaces.

[0294] It is understandable that the second side surface 500b may be provided with a gripping portion suitable for finger gripping, for example, forming at least one groove to facilitate finger gripping.

[0295] In some embodiments, see Figure 29 The central axis of the rotating shaft 420 of the cover device 400 is located inside the handle 500.

[0296] In some embodiments, see Figure 28 and Figure 29 The handle 500 is internally provided with a mounting position for the rotating shaft 420. It will be appreciated that, to accommodate the shape and rotational trajectory of the connecting member 430, the upper end of the handle 500 is provided with an accommodating space 500d for the arcuate segment 430b and the straight segment 430c. When the cover assembly 400 is in the first state, the straight segment 430c and the arcuate segment 430b are both located within the accommodating space 500d, with the straight segment 430c and the bottom wall of the accommodating space 500d being approximately parallel. When the cover assembly 400 is in the second state, the arcuate segment 430b is at least partially removed from the accommodating space 500d, with the straight segment 430c and the bottom wall of the accommodating space 500d being approximately perpendicular.

[0297] In some embodiments, see Figure 28 and Figure 29 A mounting position for installing the electrostatic release sheet 370a is provided inside the handle 500 near the second side surface 500b. For example, a notch for exposing the electrostatic release sheet 370a is provided on the second side surface 500b at the inner side of the second side surface 500b, so that when the user holds the handle 500, the electrostatic release sheet 370a can be in contact with the notch.

[0298] It is understandable that the electrostatic release sheet 370a may also be exposed from the first side surface 500a, or other places of the handle 500, as long as the electrostatic release sheet 370a is in a position where the human body can frequently come into contact with it.

[0299] In some embodiments, see Figure 28 and Figure 29One end of the support member 510 is connected to the power supply assembly 600, and the other end is connected to the fan assembly 300. Because the handle 500 and the support member 510 are supported between the power supply assembly 600 and the fan assembly 300, the overall structural strength of the cleaning device is improved. It is understood that the power supply assembly 600 can provide power to the fan assembly 300 and the display assembly 900.

[0300] In some embodiments, see 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). The power supply battery 630 and the battery management system are both located in the battery compartment 620. The battery management system is electrically connected to the power supply battery 630 and the power supply line 610, respectively. For example, the battery management system is an electronic control board, and the battery can be a cylindrical battery or a wound cell.

[0301] It is understandable that there may be multiple power supply batteries 630 , and the multiple power supply batteries 630 are arranged side by side along the arrangement direction of the power supply batteries 630 , so that the volume of the battery compartment 620 can be better utilized.

[0302] Illustratively, a plurality of power supply batteries 630 are arranged side by side along a first direction to increase the paving area of the battery compartment 620 , thereby improving the placement stability when the cleaning device is placed with the power supply assembly 600 as a base.

[0303] In some embodiments, see 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 the use of the cleaning device, the entire device needs to be tilted forward and downward, and this arrangement allows the user to complete the action more effortlessly.

[0304] In some embodiments, see Figure 28 and Figure 29 The center of gravity Q of the power supply battery 630 is located on the front side of the gripping portion of the handle 500. This arrangement allows the user to save more effort when using the cleaning device to clean.

[0305] In some embodiments, in order to facilitate charging of the power supply assembly 600, the charging connector 640 is located on the lower side of the front end of the air duct assembly 100, and 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 is routed inside the cover structure 140. The right end of the cover structure 140 is connected to the support member 510, and the charging cable continues to route along the inside of the support member 510 to reach the power supply assembly 600.

[0306] It is understandable that when the support member 510 is not provided, the cover structure 140 can be directly connected to the handle 500 , and then the charging cable continues to run along the inside of the handle 500 to reach the power supply assembly 600 .

[0307] In some embodiments, see Figure 29 Arrow P1 in the figure indicates the direction of airflow. The handle 500 is connected to the outer wall of the main housing 350. A first air passage 500c is defined within the handle 500. A fourth opening 350c is defined on the lower sidewall of the accommodating chamber 380b, communicating with the accommodating chamber 380b. The battery compartment 620 is also connected to the first air passage 500c. Therefore, airflow from the fourth opening 350c can flow along the first air passage 500c to the battery compartment 620, improving heat dissipation for the battery 630.

[0308] In some embodiments, see Figure 28 and Figure 29 The battery compartment 620 has a first opening 620a and a second opening 620b. The first opening 620a is in communication with the first air passage 500c and the inner cavity of the battery compartment 620, respectively. The second opening 620b is in communication with the outside and the inner cavity of the battery compartment 620, respectively.

[0309] In the solution of the embodiment of the present application, the first opening 620a can converge the airflow to a certain extent, thereby making the airflow flow faster and the heat dissipation efficiency of the power supply battery 630 higher. It is understandable that the first opening 620a is provided at one end of the battery compartment 620, and the second opening 620b is provided at the other end of the battery compartment 620, to further increase the convection speed. It should be noted that the embodiment of the present application is not limited to the first opening 620a being provided at one end of the battery compartment 620 and the second opening 620b being provided at the other end of the battery compartment 620. Exemplarily, the second opening 620b and / or the first opening 620a are provided between the opposite ends of the battery compartment 620.

[0310] In the related art, the heat dissipated by the battery pack is blown to the surface of the battery pack through the air outlet of the fan, thereby taking away the heat generated by the battery pack during operation. Since the air outlet of the fan is sucked into the interior of the vacuum cleaner from the outside, it carries a large amount of dust and debris. The dust cup device 200 has a filter screen, which can initially separate the air and dust and debris through the cyclone separator, and then filter the separated air through the filter screen to filter out large particles of dust in the air. The airflow passing through the filter screen will be introduced into the battery compartment to dissipate heat for the power supply battery. However, the airflow after filtering by the filter screen will still carry some fine dust. These airflows carry fine dust and blow directly to the surface of the battery management system board, which can easily cause pollution and lead to a short circuit in the battery management system. Furthermore, this part of fine dust will also leak from the opening where the battery compartment is connected to the outside world, causing secondary pollution.

[0311] In some embodiments, to solve the above problems, please refer to Figure 25 and Figure 26 A filter element 800 is provided in the accommodating cavity 380b. The filter element 800 can be arranged around the air outlet shell 380, or can be arranged at the fourth opening 350c and / or the air outlet 350b to filter the airflow entering the first air duct 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.

[0312] For example, as described above, the cleaning device also includes a motor pre-filter 291, which is arranged 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 pre-filtration. By arranging a filter element 800 in the accommodating cavity 380b, the airflow entering the first air duct 500c is filtered for the second time, which greatly improves the filtering effect.

[0313] In some embodiments, a filtering structure may be further provided in the first air channel 500c.

[0314] In some embodiments, see Figures 24 to 26 The lower sidewall of the accommodating cavity 380b is provided with a cover structure 380d, and the cover structure 380d is provided with a second through hole 380f. In this case, the fourth opening 350c is located in the area of the lower sidewall of the accommodating cavity 380b covered by the cover structure 380d. The fourth opening 350c also provides a clearance space for the connector 430, allowing the connector 430 to pass through it. Specifically, the fourth opening 350c provides a clearance space for the arc segment 430b.

[0315] It can be understood that, with respect to the above embodiment having the second through hole 380 f , the filter element 800 can be disposed at the second through hole 380 f .

[0316] It can also be understood that, with respect to the above embodiment having the second through hole 380f, the airflow filtered by the filter element 800 sequentially passes through the second through hole 380f and the fourth opening 350c before entering the first air passage 500c.

[0317] In some embodiments, see Figure 28 and Figure 29 The upper end of the handle 500 is provided with an accommodating space 500d in the arc segment 430b and the straight segment 430c. The accommodating space 500d is part of the first airway 500c. The accommodating space 500d is directly connected to the fourth opening 350c, and a connecting hole 500e is opened on the lower side wall of the accommodating space 500d.

[0318] In some embodiments, a second air duct may be provided within the support member 510. Specifically, an accommodating space 500d is provided within the arcuate segment 430b and the straight segment 430c at the upper end of the handle 500. The accommodating space 500d is directly connected to the fourth opening 350c. A connecting hole is provided on the front sidewall of the accommodating space 500d that connects to the second air duct within the support member 510, thereby allowing airflow to reach the battery compartment 620 through the second air duct. It is understood that the first air duct 500c and the second air duct may be provided simultaneously within 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 duct is provided, the first air duct 500c within the handle 500 may also be blocked.

[0319] In some embodiments, the first air channel 500c can be replaced by an air pipe 520, that is, the air inlet end of the air pipe 520 is directly connected to the fourth opening 350c, and the air pipe 520 is passed through the handle 500 and / or the support member 510 to reach the battery compartment 620 directly.

[0320] It can be understood that the air inlet end of the air pipe 520 may not be directly connected to the fourth opening 350c, but may be connected to the side wall of the accommodating space 500d at the upper end of the handle 500. This arrangement enables the air pipe 520 to be directly assembled with the internal structure of the handle 500, thereby facilitating the modular production and assembly of the handle 500.

[0321] It should be noted that a filtering structure may be further provided in the air pipe 520 to improve the filtering effect.

[0322] In some embodiments, a third air duct can be provided inside the support member 510, and the air outlet end of the third air duct can be connected to the front of the main shell 350, and the air intake end is connected to the battery compartment 620, so as to utilize vacuum suction to draw outside air into the battery compartment 620, thereby providing heat dissipation airflow for the power supply component 600, thereby greatly improving the cooling effect of the power supply battery 630.

[0323] Understandably, see Figure 28 , the third airway can be set as an airway 520.

[0324] For details, please refer to Figure 28 In the main shell 350, an air inlet space is provided on the side of the wind wheel facing the dust cup device 200, and a negative pressure area is formed in the air inlet space. The air outlet end of the air pipe 520 is connected to the air inlet space. Compared with the pressure of the accommodating chamber 380b, the suction force of the air inlet space is stronger, so the cooling effect on the power supply battery 630 is better.

[0325] In some embodiments, an air inlet grille is provided on the side of the wind wheel facing the dust cup device 200, and the front side of the air inlet grille forms the air inlet space. The air flow filtered by the motor pre-filter 291 will enter the installation cavity 350a through the air inlet grille, and the air outlet end of the air pipe 520 is connected to the air inlet space.

[0326] It can be understood that the main housing 350 is provided with a through hole through which the air supply pipe 520 passes.

[0327] In some embodiments, a sealing ring is provided at the through hole to seal the gap where the air pipe 520 passes through the through hole.

[0328] In some embodiments, see Figure 28 A channel for accommodating the trachea 520 is formed inside the support member 510, and a fixing member is provided in the channel to limit the trachea 520 so that it is stably placed in the channel.

[0329] In some embodiments, see Figure 28 A wire is provided in the handle 500, and the wire is used to transmit electricity 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. The opening is located at the connection between the battery compartment 620 and the handle 500. The first opening 620a is the above-mentioned opening, thereby avoiding the need to open a separate first opening 620a.

[0330] In some embodiments, see 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 member 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 pipe 520 is bent at the connection between the support member 510 and the battery compartment 620, and then extends along the wiring space to the first opening 602a and is connected to the first opening 602a.

[0331] The following describes the direction of airflow entering the cleaning device. It is understood that during use, the cleaning device as a whole tilts forward and downward:

[0332] For example, during the use of the cleaning equipment, the fan assembly 300 generates negative pressure, and the airflow enters the air duct assembly 100 from the air inlet, and flows to the dust cup 210 along the air inlet channel 110a of the air duct assembly 100. The airflow first enters the first dust collecting chamber 210c, passes through the first separator 241 for primary cyclone separation, and large particles of dust settle to the bottom of the first dust collecting chamber 210c. Then the unseparated fine dust follows the air to the second separator 242, and passes through the second separator 242 for secondary cyclone separation. Specifically, the air spirally descends along the guide plate in the channel 242b of the second separator 242, and the dust settles at the bottom of the second dust collecting chamber 242c. After the second separation, the airflow passes through the motor pre-filter 291 for the first filtration, and then flows into the installation cavity 350a through the air inlet grille. Specifically, the airflow first flows into the containment shell 300a through the air inlet grille, then flows out from the rear side of the containment shell 300a and enters the installation cavity 350a. The airflow flows from the installation cavity 350a into the air outlet housing 380, then flows through the first through-hole 380a of the air outlet housing 380 into the containment cavity 380b, and is filtered a second time by the filter element 800. Part of the airflow after the secondary filtration flows to the outside through 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 member 510. Specifically, the airflow enters the inner cavity of the battery compartment 620 from the first opening 620a formed in the battery compartment 620, and then flows to the outside through the second opening 620b.

[0333] It should also be noted that the cleaning device of the present application may be a pistol-shaped cleaning device. When the cleaning device is not in use or is paused during use, it is often placed horizontally with the power supply assembly 600 as the base. However, in existing cleaning devices, the axis of the motor is parallel to the placement plane V. At this time, such cleaning devices are prone to tipping forward, especially when there is a lot of dust and debris in the dust cup 210. To solve this problem, in the prior art, additional structures are often added to the tail of the power supply assembly 600 to ensure that the vacuum cleaner is placed horizontally, but this increases the cost and unnecessarily increases the volume and weight of the cleaning device.

[0334] To this end, in some embodiments of the present application, reference is made to Figure 29 As shown, the axis O of the motor 360 has an angle β with the placement plane V, β>0°. This arrangement allows the center of gravity of the vacuum cleaner to move backward, making it easier to place it horizontally.

[0335] It is understood that β can be 0.5°, 1°, 2°, 5°, etc.

[0336] To achieve "180-degree flat" cleaning, while ensuring the cleaning device remains horizontal and does not tilt forward, the tilt angle β of the axis of the fan assembly 300 can be further increased, thereby reducing the length of the power supply assembly 600 and handle 500 that protrudes backward from the cover assembly 400, thereby compressing the rear space of the cover assembly 400. In some embodiments, β satisfies the following: 5° ≥ β ≥ 1°, for example, 1°, 2°, 3°, 5°, etc.

[0337] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the specification of the present application. In particular, as long as there is no structural conflict, the various technical features mentioned in the various embodiments can be combined in any way. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions that fall within the scope of protection.
