[0090] The present application provides a cleaning device for cleaning a surface to be cleaned, which can generate negative pressure to enable dust and debris on the surface to be cleaned to enter the interior of the cleaning device. Exemplarily, the cleaning device can be a vacuum cleaner.

[0091] Exemplarily, the surface to be cleaned can be a floor or a carpet.

[0092] Exemplarily, referring to Figure 1 , the cleaning device mainly comprises the following working components: an air guide pipe assembly 100, a dust cup device 200, a fan assembly 300, a cover plate device 400, a handle 500 and a power supply assembly 600.

[0093] The functions of the above-mentioned main working components of the cleaning device are as follows:

[0094] Exemplarily, referring to Figure 3 , the air guide pipe assembly 100 comprises an air guide pipe 110, which forms an air inlet passage 110a. The air guide pipe assembly 100 is used for guiding the airflow to enable the air carrying dust and debris to enter the air inlet passage 110a, so as to pass through the air inlet passage 110a and the dust cup device 200.

[0095] Exemplarily, the dust cup device 200 can perform cyclone separation on dust and air to separate the dust and debris from the airflow, and the separated airflow will flow to the fan assembly 300.

[0096] It should be noted that, in some embodiments, referring to Figures 1 to 3, the central axis of the dust cup device 200 and the central axis of the air duct assembly 100 are staggered with each other, so that 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 under the condition that the overall length of the cleaning device is constant, the dust cup device 200 can accommodate more dust and sundries, and the problem that the user needs to frequently disassemble the dust cup device 200 for dust removal is alleviated; at the same time, such a setting can facilitate the disassembly and installation of the dust cup device 200 by the user. It can 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 can coincide.

[0097] Exemplarily, the fan assembly 300 can generate negative pressure to enable external airflow to enter the air duct assembly 100, and the separated airflow can flow to the outside through the air outlet of the fan assembly 300 after passing through the fan assembly 300.

[0098] Exemplarily, please refer to Figure 1 , the cover plate device 400 is located at the rear side of the fan assembly 300.

[0099] Exemplarily, the lower side of the fan assembly 300 is provided with a handle 500, which refers to a part for the user to hold, and the user can move the cleaning device by holding the handle 500 to clean the surface to be cleaned.

[0100] Exemplarily, the lower side of the handle 500 is also provided with a power supply assembly 600 to provide power supply for the fan assembly 300 and the like.

[0101] Next, according to the flow direction of the airflow in the cleaning device, each working component will be introduced one by one.

[0102] First, please refer to Figure 3 , which shows an air duct assembly 100, the central axis of the air duct assembly 100 and the central axis of the dust cup device 200 are staggered with each other, further refer to Figures 3 to 11 , the air duct assembly 100 comprises an air duct 110, the air duct 110 comprises a first pipe body 111 and a second pipe body 112. One end of the second pipe body 112 is connected with one end of the first pipe body 111, so as to realize the change of the airflow direction, specifically, please refer to Figure 3The sucked dust gas first flows along the first direction R1, and when reaching the rightmost end of the air guide pipe 110, it is turned to flow along the second direction R2, for example, by 80° or 90°, which is not limited herein. In the embodiment, the air guide pipe 110 is designed as a split structure, so that the first pipe body 111 and the second pipe body 112 can be independently manufactured in the mold, which reduces the difficulty of the air guide pipe 110 out of the mold. Compared with the inner pipe wall formed by the integral structure of the air guide pipe, the inner pipe wall of the first pipe body 111 and the second pipe body 112 is smoother, which improves the smoothness of the airflow, and makes the cleaning effect of the cleaning equipment more optimal.

[0103] It should be noted that the front end of the air guide pipe 110 can be connected to one or more plug-in pipes, and the front end of the plug-in pipe can be further connected to a brush or the like to adapt to different application scenarios.

[0104] In some embodiments, please refer to Figure 3 Since the first pipe body 111 and the second pipe body 112 need to realize the turning of the airflow, in order to ensure the smooth flow of the dust gas and reduce the jamming of impurities, the internal passage is arranged as an arc transition.

[0105] Specifically, in some embodiments, please refer to Figure 3 and Figure 8 At the connecting part of the first pipe body 111 and the second pipe body 112, the inner side wall of the first pipe body 111 towards the second pipe body 112 is at least partially arranged as an arc surface. It should be noted that the arc surface is located at the rear side of the central axis of the second pipe body 112.

[0106] In some other embodiments, please refer to Figure 3 and Figure 10 At the connecting part of the first pipe body 111 and the second pipe body 112, the inner side wall of the second pipe body 112 towards the first pipe body 111 is at least partially arranged as an arc surface. It should be noted that the arc surface is located at the front side of the central axis of the second pipe body 112.

[0107] It can be understood that the arc can be one of the circular arcs of a circle, or a plurality of circular arcs or a plurality of line connections to form a smooth transition line or other smooth curve.

[0108] In some embodiments, please refer to Figure 3The connecting position of the first pipe body 111 and the second pipe body 112 is provided as an arc structure 113, and the arc structure 113 includes a first curved portion 113a and a second curved portion 113b, which are located at opposite sides of the arc structure 113. It can be understood that the first curved portion 113a refers to a portion connected with the first pipe body 111 and curved towards the second pipe body 112, and the second curved portion 113b refers to a portion connected with the second pipe body 112 and curved towards the first pipe body 111.

[0109] Exemplarily, the first curved portion 113a is integrally formed with the first pipe body 111.

[0110] Exemplarily, the second curved portion 113b is integrally formed with the second pipe body 112.

[0111] In some embodiments, referring to Figure 3 and Figure 7 , the first pipe body 111 includes a straight pipe segment 111f, and the length of the straight pipe segment 111f is greater than the arc length of the first curved portion 113a, so that the cleaner can reach a position far away, thereby increasing the cleaning range and reducing the need for the user to bend over greatly during use of the cleaner, wherein the straight pipe segment 111f refers to a portion of the first pipe body 111 extending in the first direction R1.

[0112] It can be understood that the embodiments of the present application do not limit the length of the straight pipe segment 111f to be greater than the arc length of the first curved portion 113a. Exemplarily, the length of the straight pipe segment 111f is less than or equal to the arc length of the first curved portion 113a.

[0113] In some embodiments, referring to Figure 3 and Figure 4 , the first curved portion 113a includes a first end surface 111a, and the second curved portion 113b includes a second end surface 112a, and the first end surface 111a and the second end surface 112a are in contact with each other.

[0114] In the scheme of the embodiments of the present application, the first end surface 111a and the second end surface 112a are in contact with each other, so that the air guide pipe 110 has good sealing performance and the airflow can be prevented from moving between the gap between the first pipe body 111 and the second pipe body 112.

[0115] In some embodiments, referring to Figure 7 , the first end surface 111a includes a first area surface 111b and a second area surface 111c connected with each other, and the included angle formed by the intersection of the first area surface 111b and the second area surface 111c is an obtuse angle.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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 .

[0120] Illustratively, the seal is an O-ring.

[0121] Exemplarily, the sealing member is made of silicone or rubber.

[0122] 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.

[0123] 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 .

[0125] It can be understood that the connecting portion 112b is arranged on the second end surface 112a.

[0126] In the scheme of the embodiment of the present application, by arranging the sealing groove 111d on the boss 111e, the strength of the first pipe body 111 can be ensured even if the sealing groove 111d is arranged.

[0128] In some embodiments, referring to Figure 5 The connecting portion 112b includes a protrusion 112c for pressing the sealing member to reduce the gap between the first pipe body 111 and the second pipe body 112 and further improve the sealing performance.

[0129] It can be understood that the embodiment of the present application does not limit whether the connecting portion 112b is provided with the protrusion 112c.

[0130] In some embodiments, the first pipe body 111 and the second pipe body 112 can be fixed by a buckle structure. The buckle structure can be one or more.

[0131] In some embodiments, referring to Figures 6 to 11 The first pipe body 111 is provided with a first locking protrusion 1110, wherein the first locking protrusion 1110 is located on one side of the first pipe body 111 along the first direction R1, and the first locking protrusion 1110 protrudes from the first pipe body 111 along the first direction R1 (specifically, the rear direction). For example, the first locking protrusion 1110 is provided with two, respectively on both sides along the third direction R3. It can be understood that the first locking protrusion 1110 can be more than three. The second pipe body 112 is provided with a first clamping member 1121, and the first clamping member 1121 is provided with a clamping hole 1121a for clamping the first locking protrusion 1110, so that the inner wall around the clamping hole 1121a limits the first locking protrusion 1110. It can be understood that the number of the first clamping member 1121 is consistent with the number of the first locking protrusion 1110.

[0132] In some embodiments, referring to Figures 6 to 11The first pipe body 111 is further provided with a second locking protrusion 1111 located on the other side (specifically, the front side) of the first pipe body 111 along the first direction R1, and the second locking protrusion 1111 protrudes from the first pipe body 111 along a direction perpendicular to the first direction R1. For example, the second locking protrusion 1111 is provided with two protrusions along the two sides of the third direction R3. It can be understood that the second locking protrusion 1111 can be provided with more than three protrusions. The second pipe body 112 is provided with a second clamping member 1120, and the second clamping member 1120 is provided with a clamping hook 1120a abutting against the lower end surface of the first locking protrusion 1110. It can be understood that the number of the second clamping member 1120 is consistent with the number of the second locking protrusion 1111.

[0133] During installation, the clamping hole 1121a is sleeved on the first locking protrusion 1110, and then the second pipe body 112 is rotated until the clamping hook 1120a is clamped on the second locking protrusion 1111, thereby completing the assembly of the first pipe body 111 and the second pipe body 112, and achieving mutual limiting of the first pipe body 111 and the second pipe body 112 in multiple directions.

[0134] It can be understood that the embodiments of the present application do not limit the assembly mode between the first pipe body 111 and the second pipe body 112. For example, the first pipe body 111 and the second pipe body 112 can also be fixedly connected through screws or pins.

[0135] In some embodiments, referring to Figure 3 The cleaning device further comprises a sensor 700 mounted on the inner wall of the air duct 110, and the sensor 700 is used to detect the amount of dust carried by the airflow in the air duct 110, so as to adjust the power of the fan assembly 300. The greater the amount of dust, the greater the power of the fan assembly 300.

[0136] It can be understood that the cleaning device is further provided with a wire arrangement (not shown in the figure), and the wire arrangement is used to connect components such as the sensor 700. Referring to Figure 8 and Figure 9 The first pipe body 111 is provided with a wire buckle 111g for fixing the wire arrangement, so that the wire arrangement is arranged along a predetermined direction. The second pipe body 112 is provided with a avoiding gap 112d for avoiding the wire buckle 111g and the wire arrangement.

[0137] In some embodiments, referring to Figure 2 and Figure 3 The dust cup device 200 is connected and mounted on the air duct assembly 100, wherein the dust cup device 200 comprises dust cups 210 connected with each other, and the dust cup 210 has a dust collecting cavity 210a.

[0138] For further referenceFigure 3 and Figure 6 The second pipe body 112 comprises a third end surface 112e, which is used for connecting the second pipe body 112 with the air inlet 200a of the dust cup device 200 to realize the communication between the dust collection cavity 210a and the air inlet passage 110a, and guide the dust gas from the first pipe body 111 to the dust cup device 200.

[0139] In some embodiments, in order to form the air inlet passage 110a, the second pipe body 112 is provided with a guide portion 112f between the second end surface 112a and the third end surface 112e, and the air inlet passage 110a is located in the guide portion 112f.

[0140] Referring to Figure 11 In the projection plane perpendicular to the first direction R1, the axis direction of the guide portion 112f and the second direction R2 have an included angle a satisfying 0°≤a≤90°, for example, a can be 0°, 30°, 45°, 60° or 90°, etc.

[0141] In some embodiments, in the projection plane perpendicular to the first direction R1, the projection of the central axis of the second pipe body 112 and the second direction R2 have an included angle a satisfying 0°<a<90°, for example, a can be 10°, 30°, 45°, 60° or 80°, etc. By setting in this way, when the dust gas of the air guide pipe 110 enters the dust cup 210, it is easy to form a spiral airflow, which is beneficial to the cyclone separation of dust and air.

[0142] It can be understood that in some embodiments, the included angle a satisfies the condition that the dust gas enters the dust cup 210 along the tangential direction of the inner wall of the dust cup 210, and the dust gas can flow along the circumferential direction of the inner wall of the dust cup 210, which is more conducive to the formation of a spiral airflow.

[0143] In some embodiments, in order to realize the connection and fixation of the dust cup device 200 and the air guide pipe assembly 100, the air guide pipe assembly 100 comprises a first connecting piece 120, and the dust cup device 200 comprises a second connecting piece 220 arranged on the outer side wall of the dust cup 210. When the second connecting piece 220 is installed on the first connecting piece 120, the air inlet 200a and the air inlet passage 110a are communicated.

[0144] In some embodiments, referring to Figure 3 and Figure 12 The first connecting piece 120 is arranged as a connecting groove, and the second connecting piece 220 is arranged as a hook. The second connecting piece 220 can extend into the connecting groove from the slot opening of the connecting groove, so that the hook and the connecting groove are buckled with each other, thereby avoiding the situation of jamming during the installation of the dust cup device 200, and improving the disassembly efficiency.

[0145] It should be noted that the first connecting piece 120 comprises a top wall and a side wall, thereby enclosing a connecting groove, and the groove opening of the connecting groove is directed along the first direction R1 towards the dust cup device 200.

[0146] In some embodiments, the outer edge of the top wall is chamfered to facilitate the hook to be clamped.

[0147] In some embodiments, the air guide pipe 110 is integrally formed with the first connecting piece 120. Further, the side wall is in the form of an inclined straight surface, thereby facilitating the integral formation.

[0148] It can be understood that, referring to Figure 2 , the air guide pipe assembly 100 further comprises a pipe shell 130 arranged outside the air guide pipe 110, the pipe shell 130 is fixed on the air guide pipe 110 by clamping or threaded connection, and the first connecting piece 120 is formed by part of the pipe shell 130.

[0149] Specifically, the upper side region of the pipe shell 130 is formed with a gap, and the top wall is formed by the pipe shell wall located around the gap. When the hook is clamped into the connecting groove, part or all of the hook is located in the gap. Through the above arrangement, the upper side pipe shell 130 can support the dust cup device 200, and the peripheral wall of the gap can limit the second connecting piece 220, thereby improving the stability of the installation of the dust cup device 200. In addition, the above arrangement is also beneficial to the processing and manufacturing of the first connecting piece 120.

[0150] Exemplarily, the second connecting piece 220 is integrally formed with the dust cup 210.

[0151] It should be noted that the wire fixing buckle 111g and the wire are located in the gap space between the pipe shell 130 and the first pipe body 111.

[0152] In some embodiments, the dust gas entering the dust cup device 200 through the air inlet 200a can be further subjected to cyclone separation by the separation assembly 240. Specifically, referring 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 barrel cover 230, and the separation assembly 240 is located in the dust cup 210.

[0153] In some embodiments, referring to Figures 13 to 17 , the separation assembly 240 comprises a first separator 241 and a second separator 242. The first separator 241 is arranged in a cylindrical shape, and a filter screen cylinder 250 is arranged thereon, which is used for primary separation of the dust gas entering the dust cup device 200 through the second pipe body 112; the second separator 242 is located inside the cylindrical first separator 241, and is used for secondary separation of the dust gas after passing through the first separator 241.

[0154] It can be understood that the whole filter screen cylinder 250 can be made into a filter screen, or the filter screen cylinder 250 is provided with filter screens at intervals.

[0155] It can also be understood that the material of the filter screen cylinder 250 can be metal or plastic.

[0156] In some embodiments, referring to Figure 14 and Figure 15 , the cylindrical first separator 241 and the inner wall of the dust cup 210 form a first dust collecting chamber 210c. It can be understood that the first dust collecting chamber 210c is connected to the inside of the first separator 241 only through the holes on the filter screen cylinder 250. The dust gas entering the dust cup 210 forms a spiral airflow along the inner wall of the first dust collecting chamber 210c, and some impurities are left in the first dust collecting chamber 210c. The filtered gas flows into the inside of the first separator 241 through the filter screen cylinder 250.

[0157] 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.

[0158] In some embodiments, referring to Figure 15 , the first separator 241 is provided with a partition plate 243 at the rear end of the inside, and the partition plate 243 is provided with at least one third through hole 243a connected to the gas outlet 210b. The front side of the partition plate 243 is provided with a second separator 242, and the second separator 242 is provided with at least one separation unit 242a. The internal passage formed by the separation unit 242a is connected to the third through hole 243a, so that the gas flow after being separated by the second separator 242 flows to the gas outlet 210b through the third through hole 243a.

[0159] It can be understood that the number of separation units 242a is not limited in the embodiments of the present application. For example, the number of separation units 242a is single (as shown in Figure 30 ), or two, three or more (as shown in Figure 16 , Figure 32 ).

[0160] In some embodiments, referring to Figure 15 , each separation unit 242a includes an inner tube 2420 and an outer tube 2421. The inner tube 2420 is directly connected to the third through hole 243a, and the outer tube 2421 is provided at intervals with the cylinder wall of the first separator 241 to form a space 242e. At least part of the inner tube 2420 extends into the outer tube 2421, and the end of the outer tube 2421 close to the partition plate 243 is formed with an air inlet gap 242d. The gas flow after the first separation passes through the filter screen cylinder 250 into the space 242e, and enters the separation unit 242a through the air inlet gap 242d for the second separation.

[0161] It can be understood that the interval space 242e is connected with the first dust collecting chamber 210c only through the hole on the filter screen cylinder 250, and specifically, the inner side wall of the end of the filter screen cylinder 250 towards the cylinder cover 230 and the outer side wall of the outer pipe 2421 can be provided with a sealing plate for plugging.

[0162] In some embodiments, referring to Figure 14 and Figure 15 , the part of the first separator 241 inside and located at the front side of the second separator 242 constitutes a second dust collecting chamber 242c, and the second dust collecting chamber 242c is in communication with the outer pipe 2421 and the inner pipe 2420.

[0163] It can be understood that referring to Figure 15 , Figure 30 and Figure 32 , the inner pipe 2420 and the outer pipe 2421 are arranged in a spaced manner to form a channel 242b, and the airflow enters the channel 242b for secondary separation through the air inlet gap 242d.

[0164] It can be understood that in some embodiments, referring to Figure 30 and Figure 32 , the inner pipe 2420 can be arranged as an integral structure with the partition plate 243, for example, the inner pipe 2420 is formed by stamping the partition plate 243, and in some other embodiments, the inner pipe 2420 is machined separately from the partition plate 243, and the inner pipe 2420 is connected to the partition plate 243 by welding, threaded connection or the like.

[0165] It should be noted that in some embodiments, referring to Figures 15 to 17 , Figure 30 and Figure 32 , the overall length of the outer pipe 2421 is greater than the length of the inner pipe 2420 extending into the outer pipe 2421, so as to better improve the dust-gas separation effect.

[0166] It can also be understood that in some embodiments, referring to Figure 15 , the outer pipe 2421 is arranged in a spaced manner with the partition plate 243 at the end of the outer pipe 2421 along the axial direction close to the partition plate 243, thereby forming the air inlet gap 242d.

[0167] In some embodiments, referring to Figure 30 and Figure 32 , the outer pipe 2421 is connected with the partition plate 243, and an opening extending along the axis of the outer pipe 2421 is formed on the pipe wall of the end of the outer pipe 2421 close to the partition plate 243, and the opening forms the air inlet gap 242d. It can be understood that the length of the air inlet gap 242d extending along the axis of the outer pipe 2421 can be reasonably selected according to the volume of the first separator 241.

[0168] In some embodiments, referring to Figure 14 andFigure 15 The dust outlet part 244 is connected to the outer tube 2421 at an end away from the inner tube 2420, and the inner diameter of the dust outlet part 244 gradually decreases in a direction away from the outer tube 2421.

[0169] In the scheme of the embodiments of the present application, the dust outlet part 244 is generally in a conical structure, which can accelerate the rotation of the airflow, thereby making the dust falling more efficient.

[0170] It can be understood that the embodiments of the present application do not limit the shape of the dust outlet part 244. For example, the shape of the dust outlet part 244 is generally a conical cylinder.

[0171] In some embodiments, referring to Figure 30 The dust outlet end of the dust outlet part 244 is provided with a baffle 244a, and the baffle 244a and the peripheral wall of the dust outlet part 244 form a dust outlet 244c therebetween, so that the dust is discharged along the radial direction of the dust outlet part 244 and falls into the second dust collecting chamber 242c. By this arrangement, the efficiency of dust-gas separation can be improved, and the effect of dust-gas separation can be avoided when the dust outlet port of the dust outlet part 244 is large. For example, when only a small number of separation units 242a (e.g. 1, 2, etc.) are provided.

[0172] In some embodiments, referring to Figure 30 The baffle 244a and the peripheral wall of the dust outlet part 244 are connected by two or more connecting ribs 244b, and the dust outlet 244c is formed between adjacent connecting ribs 244b.

[0173] In order to form a cyclone in the separation unit 242, the following scheme can be used.

[0174] In some embodiments, referring to Figure 15 A flow guide structure 2422 is arranged in the channel 242b to guide the airflow, so that the airflow in the channel 242b forms a cyclone, thereby improving the separation effect.

[0175] Specifically, referring 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.

[0176] In some 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.

[0177] 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.

[0178] 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 .

[0179] 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.

[0180] 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.

[0181] In some embodiments, the guide plate is integrally formed with the inner tube 2420 and the outer tube 2421 .

[0182] 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.

[0183] It is understood that the embodiments of the present application are not limited to the structure that the guide vane is integrally formed with the inner tube 2420 and the outer tube 2421. For example, the guide vane, the inner tube 2420 and the outer tube 2421 can be separately manufactured and then assembled together.

[0184] In some embodiments, the gas inlet gap 242d is formed by opening the tube wall 2421 of the outer tube 2421, please refer to Figure 30 and Figure 32 The outer tube 2421 has a first tube section at one end close to the partition 243.

[0185] In some embodiments, please refer to Figure 32 The tube wall of the first tube section includes at least one second tube wall 2421c, one end of the second tube wall 2421c is closer to the axis of the outer tube 2421 than the other end of the second tube wall 2421c along the circumferential direction of the outer tube 2421, so as to form the gas inlet gap 242d at one end and / or the other end of the second tube wall 2421c. The above arrangement can make the gas flow form a cyclone along the circumferential direction of the second tube wall 2421c.

[0186] Specifically, please refer to Figure 32 The tube wall of the first tube section includes a plurality of second tube walls 2421c, the plurality of second tube walls 2421c are distributed along the circumferential direction of the outer tube 2421, and the gas inlet gap 242d is formed between the two ends of adjacent second tube walls 2421c. The above arrangement can improve the gas inlet efficiency.

[0187] In some embodiments, please refer to Figure 30 The tube wall of the first tube section includes a first tube wall 2421b and a second tube wall 2421c, one end of the first tube wall 2421b along the circumferential direction is connected to one end of the second tube wall 2421c along the circumferential direction, the other end of the first tube wall 2421b along the circumferential direction and the other end of the second tube wall 2421c along the circumferential direction are spaced apart to form the gas inlet gap 242d, and the distance between the second tube wall 2421c and the axis of the outer tube 2421 gradually increases from the connection end of the second tube wall 2421c to the free end of the second tube wall 2421c along the circumferential direction. The above arrangement can make the gas flow form a cyclone along the circumferential direction of the second tube wall 2421c and the first tube wall 2421b.

[0188] In some embodiments, please refer to Figures 30 to 32 The connection part of the first tube wall 2421b and the second tube wall 2421c is smoothly transitioned.

[0189] In some embodiments, please refer to 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.

[0190] 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.

[0191] 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.

[0192] 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.

[0193] 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.

[0194] 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 airflow. 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.

[0195] 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 .

[0196] It can be understood that at this time, the second cylinder body 270 is provided with a transition section 280 connected with the first cylinder body 260 to realize the transition of the variable inner diameter, and the transition section 280 can be provided as an annular plate 280a, a straight conical cylinder or an arc conical cylinder.

[0197] In some embodiments, referring to Figure 14 and Figure 15 , the transition section 280 is provided with 260a away from the end of the cylinder cover 230, and the blocking cylinder 260a is arranged away from the second cylinder body 270. When the cleaning device is in the working state, the blocking cylinder 260a can inhibit the dust in the first dust collecting chamber 210c, and when the airflow rolls up the dust and sundries in the first dust collecting chamber 210c, part of the dust will be blocked by the blocking cylinder 260a, thereby reducing the back rolling of the dust.

[0198] It can be understood that the blocking cylinder 260a can not be provided with a ventilation hole, or a plurality of ventilation holes, when provided with a plurality of ventilation holes, which is beneficial to the cleaning device in the working state, and the dust gas rolled up in the first dust collecting chamber 210c reaches the blocking cylinder 260a, and the airflow passes through the ventilation hole, reducing the turbulence caused by the blocking of the blocking cylinder 260a.

[0199] In some embodiments, the inner diameter of the blocking cylinder 260a is greater than the inner diameter of the filter screen cylinder 250, which can improve the dust blocking ability and further reduce the back rolling of the dust.

[0200] In some other embodiments, referring to Figure 14 and Figure 15 , the inner diameters of the filter screen cylinder 250, the first cylinder body 260 (it can be understood that in some embodiments, the first cylinder body 260 can not be provided) and the blocking 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 rotation of the airflow in the dust cup 210, through the above-mentioned setting, the cross-sectional area of the first dust collecting chamber 210c gradually increases along the axial direction close to the cylinder cover, so that the airflow intensity gradually decreases, which is beneficial to the deposition of dust at the position close to the cylinder cover 230 of the first dust collecting chamber 210c, and at the same time, due to the weak airflow intensity, the amount of dust raised is reduced.

[0201] In some embodiments, referring to Figure 14 and Figure 15 , the back side of the dust cup device 200 has a negative pressure chamber 200b, and the airflow separated by two stages of dust gas enters the negative pressure chamber 200b through the third through hole 243a, and further flows towards the fan assembly 300 under the action of negative pressure. A low-pressure buffer area is easily formed in the negative pressure chamber 200b, which improves the dust collection efficiency.

[0202] It can be understood that in some embodiments, referring to Figure 30The peripheral wall of the negative pressure chamber 200b, the partition plate 243 and the inner tube 2420 are arranged as an integral structure, for example, the peripheral wall of the negative pressure chamber 200b, the partition plate 243 and the inner tube 2420 are formed by integral casting or integral stamping.

[0203] In some embodiments, referring to Figure 14 and Figure 15 The motor pre-filter 291 is arranged in the negative pressure chamber 200b and at the air outlet 210b, so as to further filter the airflow and reduce the dust content of the airflow entering the fan assembly 300.

[0204] It can be understood that the motor pre-filter 291 can be provided with a sealing ring around the periphery to improve the sealing performance and improve the negative pressure performance.

[0205] It can also be understood that the motor pre-filter 291 can be made of filter cotton, filter material, etc.; in some embodiments, the motor pre-filter 291 can be filled in the negative pressure chamber 200b.

[0206] In some embodiments, referring to Figures 18 to 20 The rear end of the dust cup device 200 is detachably connected with the fan assembly 300. Specifically, the dust cup device 200 comprises a third connecting piece 290 connected to the dust cup 210, and the fan assembly 300 is provided with a fourth connecting piece 330, and the third connecting piece 290 and the fourth connecting piece 330 cooperate to achieve detachable installation of the dust cup device 200 and the fan assembly 300.

[0208] It can be understood that the third connecting piece 290 and the dust cup 210 can be arranged as an integral structure.

[0209] In the scheme of the embodiments of the present application, the dust cup device 200 is connected and assembled with the air guide pipe assembly 100 through the first connecting piece 120 and the second connecting piece 220, and is connected and assembled with the fan assembly 300 through the third connecting piece 290 and the fourth connecting piece 330, so as to further improve the installation stability of the dust cup device 200.

[0210] In some embodiments, referring to Figure 19 and Figure 20The fourth connecting piece 330 has a locking state and an unlocking state, that is, when the fourth connecting piece 330 is in the locking state, the fourth connecting piece 330 can lock the third connecting piece 290 to avoid the sudden situation that the dust cup device 200 is accidentally separated from the fan assembly 300 in the working process, and when the fourth connecting piece 330 is in the unlocking state, the fourth connecting piece 330 is separated from the third connecting piece 290.

[0211] Exemplarily, the fourth connecting piece 330 can rotate relative to the third connecting piece 290 to realize switching between the unlocking state and the locking state, for example, the fourth connecting piece 330 is connected to the fan assembly 300 through a rotating shaft 420, the axis direction of the rotating shaft 420 is perpendicular to the first direction R1 and the second direction R2 at the same time, so as to realize rotation of the fourth connecting piece 330; or the connection between the fourth connecting piece 330 and the fan assembly 300 can be elastically deformed to realize rotation of the fourth connecting piece 330.

[0212] Exemplarily, please refer to Figure 20 The fourth connecting piece 330 is formed with a locking groove 330a, and the third connecting piece 290 is upwardly protruding and formed with a protruding block 290a, when the fourth connecting piece 330 locks the third connecting piece 290, the protruding block 290a is at least partially located in the locking groove 330a.

[0213] In the scheme of the embodiment of the application, the locking groove 330a and the protruding block 290a cooperate to limit the movement of the dust cup device 200 in the axial direction and the circumferential direction, thereby further increasing the stability of the dust cup device 200. At the same time, the protruding block 290a of the third connecting piece 290 only needs to be upwardly protruding by a small height to realize the locking cooperation with the locking groove 330a, so that the overall structure of the dust cup device 200 is relatively flat, which is convenient for packaging.

[0214] It can be understood that in some embodiments, at least part of the fourth connecting piece 330 forming the locking groove 330a can be elastically deformed, thereby realizing the interference fit clamping of the fourth connecting piece 330 and the third connecting piece 290.

[0215] For example, at least part of the fourth connecting piece 330 forming the locking groove 330a is made of an elastic material, and specifically the elastic material includes rubber, elastomer plastic, elastic foam material, elastic textile and the like.

[0216] In some embodiments, please refer to Figure 20 The side of the third connecting piece 290 facing the negative pressure chamber 200b is formed with a buckling groove 290b, and the mounting end cover 340 of the fan assembly 300 is upwardly protruding along the radial direction and is formed with a buckling protrusion 340a, when the hook and the connecting groove are buckled with each other, the buckling protrusion 340a is at least partially located in the buckling groove 290b.

[0217] In the scheme of the embodiment of the application, the third connecting piece 290 can be fixed relative to the fan assembly 300 through cooperation of the buckling groove 290b and the buckling protrusion 340a, thereby increasing the connection strength between the dust cup 210 and the fan assembly 300.

[0218] Exemplarily, the buckling groove 290b and the protrusion 290a are respectively located on opposite sides of the third connecting piece 290 in the up-down direction.

[0219] It should be noted that the embodiment of the application does not limit whether the third connecting piece 290 is formed with the buckling groove 290b.

[0220] It can be understood that, in some embodiments, referring to Figure 20 , the mounting end cover 340 rear side is further provided with a sealing ring 320 to improve the sealing effect.

[0221] In some embodiments, referring to Figure 21 , the fourth connecting piece 330 includes a connecting head 331, a connecting handle 332 and a limiting plate 333, the locking groove 330a is arranged on the connecting head 331, the connecting handle 332 is used for connecting the fan assembly 300, the limiting plate 333 is arranged between the connecting head 331 and the connecting handle 332 and extends downward along the first direction R1, and the locking groove 330a is located on the side of the limiting plate 333 away from the connecting handle 332. When the locking groove 330a is buckled to the protrusion 290a, the limiting plate 333 can abut against the mounting end cover 340 of the fan assembly 300 to provide support force for the fourth connecting piece 330, thereby improving the assembly strength.

[0222] It should be noted that the mounting end cover 340 of the fan assembly 300 is provided with a flat-bottomed groove 340b at the corresponding position of the limiting plate 333 to increase the contact area of the bottom of the limiting plate 333 and the mounting end cover 340 and improve the support stability.

[0223] It can be understood that, referring to Figure 21 , the flat-bottomed groove 340b is located on the rear side of the buckling protrusion 340a, and when the third connecting piece 290 and the fourth connecting piece 330 are in the locked state, the protrusion 290a is located in the space enclosed by the buckling protrusion 340a, the locking groove 330a and the limiting plate 333, thereby making the locking strength higher.

[0224] It can be understood that the fourth connecting piece 330 and the third connecting piece 290 can also be locked and unlocked through other ways, for example, the fourth connecting piece 81 and the third connecting piece 290 can be in the form of cooperation of a bolt and a slot.

[0225] In some embodiments, referring to Figure 21The two support handles 334 are clamped on the fan assembly 300, and the fourth connecting piece 330 further comprises an elastic member 335, which is in contact with the support handles 334 to apply a pushing force to the support handles 334. The pushing force is used to automatically return the fourth connecting piece 330 from the unlocked state to the locked state, so as to realize automatic reset.

[0226] It can be understood that the elastic member 335 can be more than two to respectively contact the two support handles 334.

[0227] It can be understood that, referring to Figure 21 The support handle 334 is provided with a spring mounting position 337 at a corresponding position.

[0228] It can be understood that the elastic member 335 is an axial compression spring. When the fourth connecting piece 330 is in the locked state, the compression force of the compression spring is greater than or equal to 0 Newton. When the fourth connecting piece 330 changes from the locked state to the unlocked state, the compression force of the compression spring gradually increases.

[0229] In some embodiments, referring to Figure 21 The free end of each of the two support handles 334 is provided with an end shaft 336, which is rotatably arranged. It can be understood that the free end of at least one support handle 334 is provided with an end shaft 336.

[0230] It can also be understood that the application does not limit the type of elastic member 335. The elastic member 335 can also be a torsion spring.

[0231] It can also be understood that the embodiments of the application do not limit whether the fan assembly 300 is provided with the elastic member 335.

[0232] In some embodiments, referring to Figure 20 The third connecting piece 290 has a first abutting surface 290c, and the fourth connecting piece 330 has a second abutting surface 330b. During the installation of the dust cup device 200, the first abutting surface 290c can apply a pushing force to the second abutting surface 330b, so as to push the fourth connecting piece 330 to rotate relative to the fan body. Thus, when installing the dust cup device 200, the user can press the dust cup device 200 to realize that the fourth connecting piece 330 changes from the locked state to the unlocked state, which saves time and effort and provides a better user experience.

[0233] It should be noted that in the above embodiments, referring to Figure 20In the process of locking the fourth connecting piece 330 to the third connecting piece 290, the user does not directly apply force to the fourth connecting piece 330, but indirectly pushes the fourth connecting piece 330 to rotate relative to the fan body by applying force to the third connecting piece 290, so as to realize the unlocking of the fourth connecting piece 330. It can be understood that in the above process, the user can also directly apply force to the fourth connecting piece 330 to make the fourth connecting piece 330 rotate relative to the fan body, so as to realize the unlocking of the fourth connecting piece 330.

[0234] Therefore, the above two installation methods are within the protection scope of the present application.

[0235] It can be understood that the rear end face of the dust cup device 200 and the front end face of the fan assembly 300 are both inclinedly arranged to form inclined faces. Specifically, the distance between the rear end face of the dust cup device 200 and the barrel cover gradually decreases from top to bottom; the distance between the front end face of the fan assembly 300 and the barrel cover gradually decreases from top to bottom. Therefore, when the dust cup device 200 is installed to the fan assembly 300 from top to bottom, the rear end face of the dust cup device 200 and the front end face of the fan assembly 300 can be avoided from interfering with each other, and after installation, the installation gap between the two end faces can be minimized to improve the assembly precision.

[0236] The installation and disassembly process of the dust cup device 200 will be described in detail below in combination with the above structure:

[0237] When installing, first, the second connecting piece 220 is inserted into the first connecting piece 120 from the slot of the first connecting piece 120, and the front section of the dust cup device 200 is preliminarily installed on the upper side of the air duct assembly 100.

[0238] Then, the rear section of the dust cup device 200 is rotated downward with the second connecting piece 220 as the axis, so that the first abutting face 290c and the second abutting face 330b abut. Continue to apply downward pressure to the rear section of the dust cup device 200, so that the third connecting piece 290 pushes the fourth connecting piece 330 to rotate. When the dust cup device 200 is installed in place, the fourth connecting piece 330 is automatically locked to the third connecting piece 290 under the action of the elastic member 335; or the user can manually rotate the fourth connecting piece 330 to open a certain angle between the fourth connecting piece 330 and the fan assembly 300, and then rotate the other end of the dust cup device 200 downward with the second connecting piece 220 as the rotation center, so as to install the dust cup device 200 in place. The user releases the fourth connecting piece 330, so that the fourth connecting piece 330 resets and locks the third connecting piece 290.

[0239] When disassembling, the user can manually rotate the fourth connecting piece 330 so that the fourth connecting piece 330 is in the unlocked state. Then the handheld dust cup device 200 is rotated upward with the second connecting piece 220 as the rotation center until the second connecting piece 220 is detached from the slot of the first connecting piece 120.

[0240] Exemplarily, referring to Figure 3 , the distance between the third connecting piece 290 and the second connecting piece 220 along the axial direction (i.e., the first direction R1) of the dust cup device 200 is greater than or equal to half the length of the dust cup 210. By this arrangement, the constraint force between the air duct assembly 100 and the fan assembly 300 and the dust cup device 200 can be distributed on the opposite sides of the dust cup 210, reducing the length of the free end of the dust cup device 200, thereby avoiding the shaking of the dust cup device 200 during use.

[0241] In some embodiments, referring to Figure 19 , the fan assembly 300 comprises a main housing 350, and a mounting cavity 350a for mounting the motor 360 and the impeller is arranged in the main housing 350. The mounting cavity 350a is in communication with the negative pressure chamber 200b of the dust cup device 200. One end of the main housing 350 is connected with the dust cup device 200.

[0242] It can be understood that in some embodiments, the fourth connecting piece 330 is mounted on the main housing 350.

[0243] It should be noted that during use of the cleaning device, static electricity can be generated by friction between the rolling brush of the floor brush and the floor or carpet, and static electricity can also be generated by rotating friction of dust in the connector tube and the dust cup 210. If these static electricity is not released in time, the electric quantity will accumulate, and when it reaches a certain amount, it will be released by point discharge; when the user operates the vacuum cleaner, the point discharge will make the user feel electric shock, affecting the user experience; in order to eliminate these static electricity, the following methods are usually used, 1. An anti-static wire is pasted on the motor shell 360a with aluminum foil paper to release static electricity. The anti-static wire is prone to falling off after being used for a long time; 2. The dust cup 210 is injection molded with an anti-static material, but the cost is relatively high; 3. A structure protruding from the dust cup 210 is provided for arranging the static electricity sheet 370, but the appearance is poor.

[0244] In some embodiments, referring to Figure 22 , Figure 23 and Figure 28 , the motor 360 has a motor shell 360a that can conduct electricity, for example, a motor shell 360a made of metal. A damping structure 360b for damping and noise reduction is arranged on the outside of the motor shell 360a. The static electricity sheet 370 is arranged between the motor shell 360a and the damping structure 360b, and the static electricity sheet 370 is clamped and fixed by the motor shell 360a and the damping structure 360b.

[0245] It can be understood that the electrostatic sheet 370 is connected with the electrostatic discharge sheet 370a through the conductive structure 370d, and the electrostatic discharge sheet 370a can be fixed on the handle 500 or other positions easily contacted by the human body.

[0246] In some embodiments, referring to Figure 1 , the handle 500 is further provided with a support 510, the connection position of the handle 500 and the fan assembly 300 is located at the front end in the axial direction of the motor 360, and the connection position of the support 510 and the fan assembly 300 is located at the rear end in the axial direction of the motor 360, so that the support stability of the handle 500 and the support 510 to the cleaning equipment is improved. When the cleaning equipment is provided with the support 510, the electrostatic discharge sheet 370a can be fixed on the support 510.

[0247] It should be noted that when the electrostatic discharge sheet 370a is fixed on the handle 500 or the support 510, the electrostatic discharge sheet 370a is exposed through the hollow part of the handle 500 or the support 510.

[0248] It should be further noted that in some embodiments, the support 510 is located at the rear side of the dust cup device 200, so that the support 510 can more stably support the dust cup device 200 and the fan assembly 300, and the support 510 can also assist the handle 500 to play a certain holding role during use.

[0249] It should be noted that the support 510 is inclined toward the rear from top to bottom.

[0250] It can be understood that the conductive structure 370d can be a conductive wire, one end of the conductive wire is fixed on the electrostatic sheet 370 through welding, and the other end of the conductive wire is fixed on the electrostatic discharge sheet 370a through welding. In addition to the welding mode, the electric connection of the conductive structure and the electrostatic sheet 370 and the electrostatic discharge sheet 370a can also be realized through riveting, screwing and the like.

[0251] In this embodiment, after the electrostatic sheet 370 is installed, the static electricity at each position will continue to be transmitted to the user's hand through the electrostatic sheet 370, the wire harness and the electrostatic discharge sheet 370a before the static electricity is gathered, and can be transmitted to the ground through the human body, so that the concentrated discharge caused by the gathering of static electricity is avoided, and the user experience is affected.

[0252] It can be understood that in some embodiments, referring to Figure 23The electrostatic sheet 370 includes a base sheet 370b and an elastic sheet 370c. In the original state, the elastic sheet 370c is raised from the base sheet 370b. When the elastic sheet 370c is pressed by an external force, the elastic sheet 370c is pressed to the base sheet 370b. Through the arrangement, the friction between the electrostatic sheet 370 and the motor shell 360a and the rubber ring damping structure 360b is further improved, the electrostatic sheet 370 is not easy to fall off, and the conductivity is improved.

[0253] It can be understood that the original state refers to the state of the electrostatic sheet 370 when it is not installed on the fan assembly 300. It can also be understood that when the electrostatic sheet 370 is installed on the fan assembly 300, the elastic recovery force of the elastic sheet 370c will be poor due to long-term compression by the motor shell 360a and the damping structure 360b. When the electrostatic sheet 370 is removed, the elastic sheet 370c may not be raised from the base sheet 370b, but as a person skilled in the art can understand, the elastic sheet 370c is raised from the base sheet 370b in the original state.

[0254] In some embodiments, referring to Figure 23 The base sheet 370b and the elastic sheet 370c are an integral structure, for example, the elastic sheet 370c is punched on the base sheet 370b.

[0259] In some embodiments, referring to Figure 19 The air outlet shell 380 is provided with a first through hole 380a to communicate with the outside to discharge the air flow to the outside.

[0260] In some embodiments, referring to Figure 25 The containing cavity 380b is used to contain the filter 800, and the main shell 350 is provided with an air outlet hole 350b. It should be noted that the filter 800 refers to a structure capable of adsorbing fine dust in the air flow.

[0261] In some embodiments, the filter 800 is a hepa filter 250 or a sponge.

[0262] It can be understood that the embodiments of the present application do not limit the type of filter 800.

[0263] It can be understood that the filter 800 is detachably arranged in the containing cavity 380b, so that the user can conveniently replace the filter 800.

[0264] It can be understood that the filter 800 can be arranged to have a fragrance function, in addition to filtering the air flow, different fragrance flavors can also be selected according to the personal preferences of the user.

[0265] It should be noted that the fragrance function can be specially arranged as a module placed in the containing cavity 380b, and arranged separately from the filter 800.

[0266] It can be understood that the filter 800 can be arranged around the air outlet shell 380, or can be arranged only at the first through hole 380a and / or the air outlet hole 350b, to further filter the air flow discharged from the cleaning device, further improving the dust removal capacity.

[0267] In the scheme of the embodiments of the present application, the filter 800 is annular, which can be better arranged around the air outlet shell 380, so that the air flow flowing from the air outlet chamber 390a to the outside all passes through the filter 800, improving the filtering effect.

[0268] It can be understood that the embodiments of the present application do not limit the shape of the filter 800.

[0269] It can be understood that the main shell 350 of the embodiments of the present application can be arranged as an integrated structure or a split structure, when the main shell 350 is arranged as a split structure, the shell of the containing cavity 380b can be formed separately by a part of the main shell 350, thereby facilitating processing and manufacturing.

[0270] In some embodiments, referring toFigure 19 、 Figures 25 to 27 The fan assembly 300 is provided with a cover device 400 at the rear end, and the cover device 400 is movably installed on the main shell 350 to cover the opening 380c of the containing cavity 380b.

[0271] In some embodiments, referring to Figure 25 and Figure 27 The cover device 400 has a first state and a second state. When the cover device 400 is in the first state, the cover device 400 closes the opening 380c. When the cover device 400 is in the second state, the cover device 400 opens the opening 380c. The filter 800 can be moved into or out of the containing cavity 380b from the opening 380c.

During use, the user can clearly see the current state of the cleaning device. In the prior art, when the display assembly 900 is not on the cover device 400, for example, on the side of the main shell 350, the user needs to turn sideways every time to check, and may even need to pause the work before checking, which is not convenient for use.

[0275] It can be understood that, in order to improve the filtering effect, the filter 800 fills the entire containing cavity 380b. When the display assembly 900 is arranged on the side of the main shell 350, it will occupy the circumferential space of the containing cavity 380b, thereby reducing the arrangement space of the filter 800, and thus affecting the filtering effect.

[0276] In some embodiments, referring to Figures 27 to 29 The display assembly 900 is located above the handle 500, and the position of the display assembly 900 is more in line with the use habits of the user. The user can more conveniently observe the display assembly 900 during the process of holding the handle 500, thereby alleviating the obstruction of the user's arm to the line of sight, and the user's experience is better.

[0277] In some embodiments, the display assembly 900 further comprises a control button.

[0278] It can be understood that the control button comprises a physical button or a touch button. In this way, the user can conveniently operate and control the cleaning device.

Since the handle 500 and the support 510 are jointly supported between the power supply assembly 600 and the fan assembly 300, the overall structural strength of the cleaning device can be improved. It can be understood that the power supply assembly 600 can provide power to the fan assembly 300, the display assembly 900, and the like.

[0326] It can be understood that when the support 510 is not arranged, the cover structure 140 can be directly connected to the handle 500, and then the charging wire continues to run inside the handle 500 to the power supply assembly 600.

[0327] In some embodiments, referring to Figure 29 , the handle 500 is connected to the outer side wall of the main shell 350, the handle 500 is provided with a first air passage 500c penetrating through the handle 500, the lower side wall of the accommodating cavity 380b is provided with a fourth opening 350c, and the fourth opening 350c is in communication with the accommodating cavity 380b. At the same time, the battery compartment 620 is in communication with the first air passage 500c, so that the air flow discharged from the fourth opening 350c can reach the battery compartment 620 along the first air passage 500c, thereby improving the heat dissipation effect of the power supply battery 630.

[0328] In some embodiments, referring to Figure 28 and Figure 29 , the battery compartment 620 is provided with 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, and the second opening 620b is in communication with the outside and the inner cavity of the battery compartment 620 respectively.

[0329] In the scheme of the embodiment of the application, the first opening 620a can collect the air flow to a certain extent, so that the flow rate of the air flow is relatively fast, and the heat dissipation efficiency of the power supply battery 630 is relatively high. It can be understood that the first opening 620a is arranged at one end of the battery compartment 620, and the second opening 620b is arranged at the other end of the battery compartment 620, so as to further improve the convection speed. It should be noted that the embodiment of the application is not limited to that the first opening 620a is arranged at one end of the battery compartment 620 and the second opening 620b is arranged at the other end of the battery compartment 620. For example, the second opening 620b and / or the first opening 620a are arranged between the opposite ends of the battery compartment 620.

[0330] In the related art, the heat dissipation of the battery pack is achieved by blowing the air outlet of the fan to the surface of the battery pack, thereby taking away the heat generated by the battery pack during operation. Since the air outlet of the fan is sucked from the outside into the inside of the dust collector, a large amount of dust and sundries is carried, the dust cup device 200 has a filter screen, the air and the dust and sundries are preliminarily separated through the cyclone separator, then the separated air is filtered through the filter screen to filter out the large particles of dust in the air, and the air flow passing through the filter screen is introduced into the battery compartment to dissipate heat for the power supply battery. However, a part of fine dust is still carried in the air flow filtered through the filter screen, and the air flow carrying the fine dust directly blows to the surface of the battery management system board, which is easy to cause pollution and cause short circuit of the battery management system. Furthermore, the part of fine dust also leaks from the opening of the battery compartment in communication with the outside, causing secondary pollution.

[0331] In some embodiments, to solve the above problems, please refer to Figure 25 and Figure 26 , the containing cavity 380b is provided with a filter 800, which can be arranged around the air outlet shell 380, or arranged at the fourth opening 350c and / or the air outlet hole 350b, to further filter the airflow entering the first air duct 500c, further improve the dust removal capacity, and minimize the fine dust reaching the battery compartment 620, thereby reducing the influence of fine dust on the power supply battery 630 and the battery management system.

[0332] For example, as described above, the cleaning device further comprises a motor pre-filter 291 arranged between the dust cup device 200 and the fan assembly 300, for filtering the airflow flowing from the dust cup device 200 to the fan assembly 300, thereby performing a pre-filtering. By arranging the filter 800 in the containing cavity 380b, the airflow entering the first air duct 500c is filtered twice, greatly improving the filtering effect.

[0333] In some embodiments, the first air duct 500c can be further provided with a filtering structure.

[0334] In some embodiments, please refer to Figures 24 to 26 , the containing cavity 380b is provided with a cover structure 380d on the lower side wall, and the cover structure 380d is provided with a second through hole 380f. At this time, the fourth opening 350c is located in the area of the lower side wall of the containing cavity 380b covered by the cover structure 380d, and the fourth opening 350c provides a space for the connecting piece 430 to pass through. Specifically, the fourth opening 350c provides a space for the arc-shaped section 430b.

[0335] It can be understood that, for the above embodiment with the second through hole 380f, the filter 800 can be arranged at the second through hole 380f.

[0336] It can also be understood that, for the above embodiment with the second through hole 380f, the airflow filtered by the filter 800 passes through the second through hole 380f, the fourth opening 350c, and then enters the first air duct 500c.

[0337] In some embodiments, please refer to Figure 28 and Figure 29 , the handle 500 is provided with a containing space 500d at the upper end of the arc-shaped section 430b and the straight section 430c. The containing space 500d is part of the first air duct 500c, and the containing space 500d is in direct communication with the fourth opening 350c. The lower side wall of the containing space 500d is provided with a communication hole 500e.

[0338] In some embodiments, a second air passage can be arranged inside the support 510. Specifically, the upper end of the handle 500 is provided with an accommodation space 500d, which is arranged at the arc-shaped section 430b and the straight section 430c and directly communicates with the fourth opening 350c. A communication hole is arranged on the front side wall of the accommodation space 500d and communicates with the second air passage inside the support 510, so that the air flow reaches the battery compartment 620 through the second air passage. It can be understood that the first air passage 500c and the second air passage can be arranged in the handle 500 and the support 510 at the same time, so as to provide multiple channels to reach the battery compartment 620. It can also be understood that when the second air passage is arranged, the first air passage 500c inside the handle 500 can also be blocked.

[0339] In some embodiments, the first air passage 500c can be replaced by the 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 arranged inside the handle 500 and / or the support 510 and directly reaches the battery compartment 620.

[0340] It can be understood that the air inlet end of the air pipe 520 can not be directly connected to the fourth opening 350c, but can be connected to the side wall of the accommodation space 500d at the upper end of the handle 500. By this arrangement, the air pipe 520 can be directly assembled with the internal structure of the handle 500, which facilitates the modular production and assembly of the handle 500.

[0341] It should be noted that a filtering structure can be further arranged in the air pipe 520 to improve the filtering effect.

[0342] In some embodiments, a third air passage can be arranged inside the support 510. The air outlet end of the third air passage can be connected to the front of the main shell 350, and the air inlet end can be connected to the battery compartment 620, so as to use the vacuum suction to suck the air outside into the battery compartment 620, thereby providing a cooling air flow for the power supply assembly 600, and greatly improving the cooling effect of the power supply battery 630.

[0343] It can be understood that, as shown in Figure 28 , the third air passage can be the air pipe 520.

[0344] Specifically, as shown in Figure 28 , the side of the main shell 350, where the air wheel faces the dust cup device 200, is provided with an air inlet space, a negative pressure area is formed in the air inlet space, the air outlet end of the air pipe 520 communicates with the air inlet space, and the suction force of the air inlet space is stronger than the pressure of the containing cavity 380b. Therefore, the cooling effect of the power supply battery 630 is more optimal.

[0345] In some embodiments, the wind wheel is provided with an air inlet grille on one side of the dust cup device 200, and the front side of the air inlet grille forms the air inlet space. The airflow filtered by the motor front filter 291 enters the installation cavity 350a through the air inlet grille. The air outlet end of the air pipe 520 is in communication with the air inlet space.

[0346] It can be understood that the main shell 350 is provided with a through hole through which the air pipe 520 passes.

[0347] In some embodiments, a sealing ring is arranged at the through hole to seal the gap through which the air pipe 520 passes.

[0348] In some embodiments, referring to Figure 28 , the support 510 is internally formed with a channel for accommodating the air pipe 520. The channel is provided with a fixing member for limiting the air pipe 520, so that the air pipe 520 is stably arranged in the channel.

[0349] In some embodiments, referring to Figure 28 , the handle 500 is provided with a wire for delivering power from the power supply assembly 600 to the display assembly 900, the fan assembly 300, etc. The wire is connected to the power supply battery 630 through an opening in the battery compartment 620. The opening is located at the connection part of the battery compartment 620 and the handle 500, and the first opening 620a is the above-mentioned opening, thereby avoiding opening the first opening 620a.

[0350] In some embodiments, referring to Figure 28 , the first opening 620a is located at the connection part of the battery compartment 620 and the handle 500. The lower ends of the support 510 and the handle 500 are connected by a connecting shell, and a wire 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 part of the support 510 and the battery compartment 620, then extends along the wire space to the first opening 602a, and is connected to the first opening 602a.

[0351] The flow direction of the airflow entering the cleaning device is described below. It can be understood that during use, the cleaning device is inclined downwardly and forwardly as a whole.

[0352] Exemplarily, during use of the cleaning device, the fan assembly 300 works to generate negative pressure, air flow 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 air flow first enters the first dust collecting chamber 210c, and is subjected to first cyclone separation by the first separator 241, and large particles of dust fall to the bottom of the first dust collecting chamber 210c. Then, the unseparated fine dust is subjected to second cyclone separation by the second separator 242. Specifically, the air spirally descends in the channel 242b of the second separator 242, and the dust falls to the bottom of the second dust collecting chamber 242c. After the air flow is subjected to the second separation, it is filtered for the first time by the motor front filter 291, and then flows to the installation cavity 350a through the air inlet grille. Specifically, the air flow first flows into the containing shell 300a through the air inlet grille, and then flows out from the rear side of the containing shell 300a into the installation cavity 350a. The air flow flows from the installation cavity 350a into the containing cavity 380b through the first through hole 380a of the air outlet shell 380, is subjected to second filtration by the filter 800, and part of the air flow subjected to the second filtration flows to the outside through the air outlet, and part of the air flow flows to the battery compartment 620 along the air duct formed by the handle 500 and / or the support 510. Specifically, the air flow enters the inner cavity of the battery compartment 620 from the first opening 620a of the battery compartment 620, and then flows to the outside through the second opening 620b.

[0353] It should be further noted that, for the cleaning device of the present application, it can specifically be a pistol-type cleaning device, and during non-use or during suspension of use, the cleaning device is often placed horizontally with the power supply assembly 600 as the base. In the existing cleaning device, the shaft center line of the motor is parallel to the placement plane V, and at this time, the cleaning device is prone to forward tilting, especially when there is a large amount of dust and sundries in the dust cup 210. To solve this problem, in the prior art, an additional structure is often added to the tail of the power supply assembly 600 and the like to ensure that the cleaner is placed horizontally, but this results in an increase in cost, and unnecessary increase in the size and weight of the cleaning device.

[0354] Therefore, in some embodiments of the present application, with reference to Figure 29 It is shown that the shaft center line O of the motor 360 has an angle β with the placement plane V, and β>0°. Thus, the center of gravity of the cleaner is set to move backward, which facilitates horizontal placement.

[0355] It can be understood that β can be 0.5°, 1°, 2°, 5°, etc.

[0356] 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.

[0357] 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.
