[0078] With reference to Figure 1 , Figure 2 , Figure 3 A cleaning device 100 according to an embodiment of the present application includes a locking assembly 10 and an upper body 20 and a lower body 50 pivotally connected to each other.

[0079] The upper body 20 includes an upper housing 21 and a motor 70 accommodated in the upper housing 21, and the lower body 50 includes a lower housing 51 and a dust cup module 80 accommodated in the lower housing 51, the motor 70 being configured to provide suction force to suck dirt in a region to be cleaned to the dust cup module 80, and the locking assembly 10 being configured to lock the upper body 20 and the lower body 50 in a first state shown in Figure 1 , Figure 3 In the first state, the upper housing 21 covers the lower housing 51, and the motor 70 is in fluid communication with the dust cup module 80.

[0080] In addition, the cleaning device 100 further includes a hinge assembly 30, and the upper body 20 and the lower body 50 are pivotally connected through the hinge assembly 30.

[0081] By pivotally connecting the upper body 20 and the lower body 50, the upper body 20 can be folded relative to the lower body 50, so as to reduce the space occupied by the cleaning device 100 in a storage state. In addition, compared with the cleaning device in the related art, when the cleaning device is folded and stored, the dust cup is rotated and the dust stored at the bottom is poured to the upper part, in the cleaning device 100 according to an embodiment of the present application, the dust cup module 80 is accommodated in the lower housing 51, and when the upper body 20 is folded relative to the lower body 50 in the folding and storage state, the position of the dust cup module 80 located in the lower body 50 does not change and the upper and lower parts are not reversed, so that the situation that the dirt at the bottom of the dust cup module 80 is poured to the upper part can be effectively avoided. When the upper body 20 and the lower body 50 are changed to the first state again, the working state of the dust cup module 80 is not affected, and the cleaning efficiency and the working reliability of the cleaning device 100 can be ensured to be high.

[0082] In addition, in the normal use state of the cleaning device 100, the upper body 20 is located above the lower body 50, and the upper body 20 is closer to the position of the human head than the lower body 50. In the first state, the upper shell 21 is covered on the lower shell 51, and the motor 70 is in fluid communication with the dust cup module 80. In this way, the motor 70 can provide suction to suck the dirt in the area to be cleaned to the dust cup module 80. The upper shell 21 and the lower shell 51 can each be configured with an open-ended accommodation cavity. The upper shell 21 is covered on the lower shell 51, for example, the openings of the upper shell 21 and the lower shell 51 can be opposite to each other, and the accommodation cavities of the upper shell 21 and the lower shell 51 can be combined together to form a large accommodation cavity. The fluid communication between the motor 70 and the dust cup module 80 can be that the inlet of the motor 70 is in communication with the outlet 81 of the dust cup module.

[0083] Further, the upper body 20 and the lower body 50 also include a second state that is separated from each other, as shown in the second state, the upper shell 21 is separated from the lower shell 51, and the motor 70 is fluidly disconnected from the dust cup module 80. Specifically, the upper shell 21 can be attached to the side of the lower shell 51 after being turned over. Figure 2

[0084] Since the motor 70 and the dust cup module 80 are fluidly disconnected in the second state, the cleaning device 100 is in a non-working state, which can avoid the problem that the connection channel between the motor 70 and the dust cup module 80 is repeatedly bent and easily broken. It can be understood that in the first state, the openings of the accommodation cavities of the upper shell 21 and the lower shell 51 are combined together, and in the second state, the upper shell 21 is rotated relative to the lower shell 51, so that the accommodation cavities of the upper shell 21 and the lower shell 51 respectively enter the open state.

[0085] The structure of the locking assembly 10 will be described below. Referring to Figure 4 and Figure 5 , Figure 4 for the sake of observation, the upper shell 21 is omitted, Figure 4 the upper side of the figure in the figure is the first state, Figure 4 the lower side of the figure in the figure is the second state. The locking assembly 10 includes a second pressing member 11, and the second pressing member 11 is provided with a first matching part 111 and a second matching part 112.

[0086] The first matching part 111 is connected to one of the upper body 20 and the lower body 50, and the second matching part 112 is in clamping cooperation with the other of the upper body 20 and the lower body 50.

[0087] ​In this way, the second engaging portion 112 is engaged with the other one of the upper body 20 and the lower body 50, so that the upper body 20 and the lower body 50 are locked, and when the engagement is released, the upper body 20 can rotate relative to the lower body 50 to be folded. In practice, the first engaging portion 111 can be connected to the upper body 20, and the second engaging portion 112 is engaged with the lower body 50, or the first engaging portion 111 can be connected to the lower body 50, and the second engaging portion 112 is engaged with the upper body 20.

[0088] Further, the locking assembly 10 further comprises a first elastic member 12, two ends of the first elastic member 12 are connected to the upper body 20 and one end of the second pressing member 11 respectively, and the first elastic member 12 always applies an elastic force to the second pressing member 11 away from the upper body 20. The second engaging portion 112 is connected to the other end of the second pressing member 11 and is engaged with the lower body 50. The first engaging portion 111 is connected to a position between the two ends of the second pressing member 11 and is rotatably connected to the upper body 20.

[0089] In this way, since the first elastic member 12 always applies an elastic force to one end of the second pressing member 11 away from the upper body 20, and the part between the two ends of the second pressing member 11 is rotatably connected to the upper body 20 through the first engaging portion 111, the second engaging portion 112 connected to the other end of the second pressing member 11 has a movement tendency to the lower body 50 all the time, and the second engaging portion 112 is engaged with the lower body 50, so that the second engaging portion 112 can be firmly limited in the engagement position.

[0090] In practice, the first engaging portion 111, the second engaging portion 112 and the first elastic member 12 are all located on the same side of the second pressing member 11, i.e. on the side of the second pressing member 11 facing the upper body 20 and the lower body 50.

[0091] In the embodiment of the present application, the first engaging portion 111 and the second engaging portion 112 are engaged with the upper body 20 and the lower body 50 respectively. Figure 3 and Figure 4 The upper shell 21 is provided with a first outer lining shell 22 on the outer side, the first outer lining shell 22 and the upper shell 21 jointly define a first installation cavity 97, and the first elastic member 12 and the second pressing member 11 are installed in the first installation cavity 97. The upper shell 21 is provided with a first avoiding gap 211 corresponding to the position of the second pressing member 11, the first engaging portion 111 passes through the first avoiding gap 211 and is rotatably connected to the upper shell 21, and the first elastic member 12 is located in the first avoiding gap 211.

[0092] In this way, the second pressing member 11 can be exposed to the outside from the first avoiding gap 211 for an operator to press, and the first engaging portion 111 will be blocked between the second pressing member 11 and the upper shell 21.

[0093] Further, the first matching part 111 is in number of two, and the two first matching parts 111 are arranged at intervals. The outer wall of the upper casing 21 is provided with two support arms 212 arranged at intervals, and the two first matching parts 111 are hingedly connected to the two support arms 212 one by one. In this way, the two first matching parts 111 can be hingedly connected to the corresponding support arms 212. Of course, the first matching part 111 is provided with a hinge shaft 1111 towards the end of the support arm 212, and the corresponding support arm 212 is provided with a matching hole 1112, the hinge shaft 1111 is inserted into the matching hole 1112 and can rotate relative to the matching hole 1112. The matching relationship between the second matching part 112 and the support arm 212 is similar to this, which will not be described here.

[0094] In the embodiments of the present application, continuing to refer to Figure 3 The cleaning device 100 further comprises a cleaning module 40. The upper body 20 further comprises a control board (not shown) and an upper coupler 23, and the lower body 50 further comprises a lower coupler 53. The upper coupler 23, the motor 70 and the control board are electrically connected, and the lower coupler 53 and the cleaning module 40 are electrically connected.

[0095] Referring to Figure 4 In the first state, the upper coupler 23 and the lower coupler 53 are inserted and electrically connected with each other, and in the second state, the upper coupler 23 is separated from the lower coupler 53 and electrically disconnected. The control board is used to control the motor 70 to stop operating when the upper coupler 23 and the lower coupler 53 are electrically disconnected. The upper coupler 23 can be a female plug-in end, for example, and the lower coupler 53 can be a male plug-in end, for example.

[0096] By arranging the upper coupler 23 and the lower coupler 53, and in the first state, the upper coupler 23 and the lower coupler 53 can be electrically connected with each other. In this way, in the first state, the control board realizes electrical connection with the lower coupler 53 through electrical connection with the upper coupler 23, thereby realizing electrical connection with the cleaning module 40, so that the cleaning device 100 can work normally. In the second state, the upper coupler 23 and the lower coupler 53 are electrically disconnected, the control board controls the motor 70 to stop operating, and the connection between the control board and the cleaning module 40 is disconnected, so that the motor 70 and the cleaning module 40 are both in a stop operating state, to avoid the motor 70 and the dust cup module 80 still being in a power-on state after the motor 70 and the dust cup module 80 are fluidically disconnected, resulting in a misoperation, and avoid that foreign matters are directly sucked into the motor 70 without passing through the dust cup module 80, thereby damaging the motor 70.

[0097] The upper coupler 23 can be installed on the upper casing 21 by a fastener such as a screw, and the lower coupler 53 can be installed on the lower casing 51 by a fastener such as a screw. In addition, the cleaning module 40 can comprise a first cleaning module 41 and a second cleaning module 42.

[0098] Further, the lower coupling 53 is provided with a clamping groove 531 corresponding to the position of the second matching part 112 when the first matching part 111 is connected to the upper body 20, and the clamping groove 531 is used for clamping matching of the second matching part 112.

[0099] In a specific implementation, the lower shell 51 is provided with a second outer lining 54, and the second outer lining 54 and the lower shell define a containing cavity, and the lower coupling 53 is installed in the containing cavity. The second outer lining is provided with a second avoiding gap 541 for exposing the lower coupling 53. In addition, the upper coupling 23 can be installed in a first installation cavity 97 defined by the first outer lining 22 and the upper shell 21.

[0100] Further, referring to Figure 6 , the upper shell 21 is formed with a first filtering cavity 91, the first filtering cavity 91 is provided with a first filtering piece 221, and the outlet of the first filtering cavity 91 is connected with the inlet of the motor 70.

[0101] In the second state, the first filtering piece 221 in the first filtering cavity 91 can close the inlet of the motor 70, so that foreign matters cannot enter the motor 70 from the inlet of the motor 70 in the second state.

[0102] In the embodiment of the present application, in combination with Figure 3 and Figure 4 , in the first state, the outlet 81 of the dust cup module and the inlet 910 of the first filtering cavity are located between the hinge assembly 30 and the upper coupling 23 and the lower coupling 53. In this way, when the upper body 20 is switched from the first state to the second state relative to the lower body 50, the upper coupling 23 and the lower coupling 53 are far away from the hinge assembly 30 and are separated first to achieve electrical disconnection, and then the outlet 81 of the dust cup module and the inlet 910 of the first filtering cavity which are relatively close to the hinge assembly 30 are separated. This can make the motor 70 power off first and then achieve fluid disconnection between the motor 70 and the dust cup module 80, so as to avoid the situation that the motor 70 is misoperated before fluid disconnection and foreign matters enter the motor 70.

[0103] In the embodiment of the present application, in combination with Figure 3 and Figure 7 , the outlet 81 of the dust cup module and the inlet 910 of the first filtering cavity are opposite to each other, and in the first state, the outlet 81 of the dust cup module and the inlet 910 of the first filtering cavity are sealed and matched by the first sealing piece 52 to make the dust cup module 80 and the first filtering cavity 91 communicate.

[0104] The cleaning device 100 further comprises a battery 71, which can be electrically connected with the control board. The battery 71 is arranged on the side of the motor 70 away from the first filtering cavity 91. In the second state, the battery 71, the motor 70 and other heavy components are all located below the first filtering cavity 91, so that the gravity center is low, and the cleaning device 100 is stable during the process of being held by the operator in the second state.

[0105] Further, referring to Figure 7 , the outlet 81 of the dust cup module defines a sealing element mounting groove 811. The inlet 910 of the first filtering cavity is inserted into the sealing element mounting groove 811 through the first sealing element 52.

[0106] In this way, in the first state, the first sealing element 52 can realize the sealing between the inlet 910 of the first filtering cavity and the outlet 81 of the dust cup module. In the second state, when the upper machine body 20 is folded relative to the lower machine body 50, the first sealing element 52 is mounted in the sealing element mounting groove 811 and is not easy to fall off.

[0107] Further, referring to Figure 6 The upper machine body 20 further comprises a support cover 24, one end of the support cover 24 is connected with a support net 25. The support net 25 and the support cover 24 are located inside the upper machine shell 21, and the support net 25 and the inner wall of the upper machine shell 21 together define a ring-shaped first filtering element mounting cavity 92, and the first filtering element 221 is mounted in the first filtering element mounting cavity 92. The support cover 24 protrudes from the first filtering element 221 along the length direction of the cleaning device 100 and is connected to the inlet of the motor 70.

[0108] In this way, the fluid to be filtered from the outlet 81 of the dust cup module passes through the ring-shaped first filtering element mounting cavity 92, and the filtered fluid enters the inside of the support net 25 and passes through the support cover 24 to enter the inlet of the motor 70. At this time, the first filtering element mounting cavity 92, the space inside the support net 25 and the space inside the support cover 24 together define the first filtering cavity 91.

[0109] Further, the support cover 24 and the upper machine shell 21 define a ring-shaped second filtering cavity 93, and the second filtering cavity 93 is provided with a second filtering element 222. The second filtering cavity 93 is in communication with the air outlet of the motor 70 and the outside.

[0110] In this way, the gas of the motor 70 is discharged downward, filtered by the second filtering element 222 when passing through the second filtering cavity 93, and then discharged to the outside. Of course, the upper machine shell 21 can be provided with a plurality of openings 210 corresponding to the position of the second filtering element 222, so as to allow the gas to flow out of the second filtering cavity 93.

[0111] The structure of the hinge assembly 30 will be described below. As mentioned above, the upper body 20 and the lower body 50 are pivotally connected by the hinge assembly 30.

[0112] Figure 8 And Figure 9 In the figure, the left side of the figure is a schematic view of the hinge assembly 30 in the first state, and the right side of the figure is a schematic view of the hinge assembly 30 in the second state. Referring to Figure 8 And Figure 9 The hinge assembly 30 comprises an upper base body 33 and a lower base body 34, two first hinge arms 31 and two second hinge arms 32.

[0113] The upper base body 33 and the lower base body 34 are respectively connected to the upper body 20 and the lower body 50.

[0114] The two first hinge arms 31 are oppositely arranged, and the two second hinge arms 32 are respectively arranged on the inner sides of the two first hinge arms 31 facing each other. The first ends 311 of the two first hinge arms are hingedly connected by a first shaft 351, and the second ends 312 of the two first hinge arms are respectively hingedly connected to the lower base body 34 by a second shaft 352. The first ends 321 of the two second hinge arms are hingedly connected by a third shaft 353, and the second ends 322 of the two second hinge arms are respectively hingedly connected to the lower base body 34 by a fourth shaft 354. The middle parts of the corresponding first hinge arms 31 and second hinge arms 32 are hingedly connected to each other by a fifth shaft 355. In this way, the size of the hinge structure can be made smaller, and the rotation angle of the upper base body 33 and the lower base body 34 can be made larger.

[0115] Further, the upper base body 33 is provided with a first sliding rail 331 corresponding to the positions of the two ends of the first shaft 351, and the lower base body 34 is provided with two second sliding rails 341 corresponding to the positions of the fourth shaft 354. The two ends of the first shaft 351 are respectively slidably connected in the two first sliding rails 331, and the two ends of the fourth shaft 354 are respectively slidably connected in the two second sliding rails 341.

[0116] In this way, the first sliding rail 331 can limit the first end 311 of the first hinge arm, so that the first end 311 of the first hinge arm moves along the extension direction of the first sliding rail 331, and the second sliding rail 341 can limit the second end 322 of the second hinge arm, so that the second end 322 of the second hinge arm moves along the extension direction of the second sliding rail 341.

[0117] When the upper base 33 rotates relative to the lower base 34, the fourth shaft 354 moves along the extension direction of the second sliding rail 341 under the drive of the second hinged arm 32, the second end 322 of the second hinged arm moves along the extension direction of the second sliding rail 341, and the second hinged arm 32 also rotates around the fifth shaft 355. At this time, the first shaft 351 moves along the extension direction of the first sliding rail 331 under the drive of the first hinged arm 31, the first end 311 of the first hinged arm moves along the extension direction of the first sliding rail 331, and the first hinged arm 31 also rotates around the fifth shaft 355, until the second end 322 of the second hinged arm moves to the corresponding position of the end of the second sliding rail 341, and the first end 311 of the first hinged arm moves to the corresponding position of the end of the first sliding rail 331. As shown in the diagram on the right side of the figure in Figure 8 、 9 When the upper base 33 rotates relative to the lower base 34, the fourth shaft 354 moves along the extension direction of the second sliding rail 341 under the drive of the second hinged arm 32, the second end 322 of the second hinged arm moves along the extension direction of the second sliding rail 341, and the second hinged arm 32 also rotates around the fifth shaft 355. At this time, the first shaft 351 moves along the extension direction of the first sliding rail 331 under the drive of the first hinged arm 31, the first end 311 of the first hinged arm moves along the extension direction of the first sliding rail 331, and the first hinged arm 31 also rotates around the fifth shaft 355, until the second end 322 of the second hinged arm moves to the corresponding position of the end of the second sliding rail 341, and the first end 311 of the first hinged arm moves to the corresponding position of the end of the first sliding rail 331. As shown in the diagram on the right side of the figure in

[0118] The first hinged arm 31 and the second hinged arm 32 can both be in the shape of the English letter "C", the upper base 33 can be connected to the upper casing 21, and the lower base 34 can be connected to the lower casing 51.

[0119] Further, the hinge assembly 30 further comprises an intermediate body 36, which is clamped between the two second hinged arms 32 and is hingedly connected to the third shaft 353, the fifth shaft 355 and the fourth shaft 354, respectively.

[0120] In this way, the intermediate body 36 is isolated between the two second hinged arms 32, so as to facilitate maintaining the spacing between the two second hinged arms 32 and improving the reliability of the hinge assembly 30 during operation.

[0121] Further, one of the upper base 33 and the lower base 34 is provided with a plug-in slot 330, and the other is provided with a plug-in block 340 which can be plugged into the plug-in slot 330. In the first state, the plug-in block 340 is plugged into the corresponding plug-in slot 330. In this way, in the first state, the plug-in slot 330 and the plug-in block 340 can assist in positioning and prevent the upper base 33 and the lower base 34 from rotating relative to each other.

[0122] In the embodiment of the present application, with reference to Figure 10 The two ends of the first shaft 351 and the second shaft 352 are respectively provided with a first shaft shoulder structure 3510 and a second shaft shoulder structure 3520.

[0123] Among the first ends 311 of the two first hinged arms, the wall portions facing each other abut against the two first shaft shoulder structures 3510. Among the second ends 312 of the two first hinged arms, the wall portions facing each other abut against the two second shaft shoulder structures 3520.

[0124] The two ends of the third shaft 353 and the fourth shaft 354 are respectively provided with third shaft shoulder structures 3530 and fourth shaft shoulder structures 3540. In the first ends 321 of the two second hinged arms, the wall portions facing each other abut against the two third shaft shoulder structures 3530. In the second ends 322 of the two second hinged arms, the wall portions facing each other abut against the two fourth shaft shoulder structures 3540.

[0125] In this way, the first shaft shoulder structures 3510 and the second shaft shoulder structures 3520 are used to position the two first hinged arms 31, and the third shaft shoulder structures 3530 and the fourth shaft shoulder structures 3540 are used to position the two second hinged arms 32.

[0126] In the embodiments of the present application, the first hinged arms 31 and the second hinged arms 32 are respectively provided with Figure 2 and Figure 3 As described above, the cleaning module 40 includes a first cleaning module 41 and a second cleaning module 42. The first cleaning module 41 is connected to the dust cup module 80, and the second cleaning module 42 is detachably installed on the dust cup module 80, so as to have Figure 2 the installation state shown in FIG. 5A and Figure 3 the disassembly state shown in FIG. 5B.

[0127] In the installation state, the second cleaning module 42 is installed on the dust cup module 80 and communicates with the dust cup module 80, and the cleaning device 100 has a fluid recovery path, the second cleaning module 42 and the first cleaning module 41 are arranged in sequence along the fluid recovery path, and part of the second cleaning module 42 passes through the first cleaning module 41 and communicates with the dust cup module 80. In the disassembly state, the second cleaning module 42 is separated from the dust cup module 80.

[0128] In this way, in the disassembly state, the second cleaning module 42 is separated from the dust cup module 80, so that the first cleaning module 41 can be used alone for local cleaning. In the installation state, the second cleaning module 42 and the first cleaning module 41 are arranged in sequence along the fluid recovery path, and part of the second cleaning module 42 passes through the first cleaning module 41 and communicates with the dust cup module 80, so that the garbage and airflow mixture can be sucked from the second cleaning module 42 and directly flow into the dust cup module 80. In this way, in the installation state, part of the second cleaning module 42 passes through the first cleaning module 41 and communicates with the dust cup module 80, so that there is only a sealing requirement between the second cleaning module 42 and the dust cup module 80, and the fluid only passes through a place of unevenness on the flow path, and the flow path is relatively smoother, so that the fluid flow is smoother, the energy loss is smaller, so that the second cleaning module 42 can provide stronger suction, and the cleaning efficiency is also higher.

[0129] In the embodiments of the present application, refer to Figure 1 , Figure 2The distance between the end of the lower body 50 on the side facing the upper body 20 and the end of the first cleaning module 41 on the side facing away from the upper body 20 is defined as a first length L1; the first length L1 is greater than or equal to a second length L2 between the two ends of the upper body 20.

[0130] That is, the folding position of the upper body 20 and the lower body 50 is closer to the motor 70 in the entire cleaning device 100. By such an arrangement, the overall size of the entire cleaning device 100 is smaller when the second cleaning module 42 is in the mounted state. In addition, preferably, the first length L1 is substantially equal to the length between the two ends of the upper body 20, and the folding state of the assembly of the upper body 20, the lower body 50, and the first cleaning module 41 is substantially in a half-folded state when the second cleaning module 42 is in the dismounted state, which can reduce the storage size of the entire cleaning device 100. In a specific implementation, the second length L2 of the upper body 20 can be 504 mm, and the first length L1 can be 446 mm. The length L3 of the second cleaning module 42 can be 281 mm.

[0131] In the embodiments of the present application, with reference to Figure 4 , Figure 11 , the cleaning device 100 further comprises a handle assembly 60, the handle assembly 60 comprises a handle 61, and the handle assembly 60 is arranged on the lower body 50. The handle assembly 60 is arranged in a handle accommodating cavity 94 in the lower body 50, so that when the upper body 20 is folded relative to the lower body 50, the cleaning assembly can be lifted by operating the handle 61 for carrying.

[0132] In some embodiments, the handle 61 comprises a base portion 614 and two extension portions 615 connected to the two opposite ends of the base portion 614, so that the handle 61 is configured as a semi-closed structure with an opening. Figure 12 In the first state, the opening of the handle 61 faces the hinge assembly 30, as shown in the lower side view.

[0133] In this way, during the switching from the second state to the first state, the first pressing piece 26 in the upper body 20 can press against the handle 61, and with the rotation of the upper body 20, the first pressing piece 26 can press the handle 61 to rotate in the direction away from the hinge assembly 30 into the handle accommodating cavity 94. In a specific implementation, the handle 61 as a whole can be configured as a letter "U" type or "C" type structure.

[0134] Further, with reference to Figure 11 , the upper housing 21 and the lower housing 51 are both configured as a cover-shaped member with one end open.

[0135] The dust cup module 80 includes a filter 83 and a tubular extension hood 82 extending toward the upper body 20, with the side end of the extension hood 82 facing away from the dust cup module 80 forming the outlet 81 of the dust cup module.

[0136] The extension cover 82 is located inside the open end of the lower housing 51, and the handle 61 is rotatably connected to the extension cover 82 and located in the annular handle receiving cavity 94 defined by the extension cover 82 and the lower housing 51.

[0137] With this configuration, when the cleaning device 100 is in the first state, the handle 61 can be stored in the handle receiving cavity 94, such as... Figure 12 As shown in the lower part of the diagram, when the upper body 20 is folded relative to the lower body 50, the handle 61 protrudes from the lower housing, facilitating lifting by the operator. Figure 12 The image shown is located on the upper part of the middle panel.

[0138] Reference Figure 11 and Figure 12 The lower housing 51 defines an open lower receiving cavity 96, and the upper housing 21 defines an open upper receiving cavity 95. A dust cup module 80 is disposed in the lower receiving cavity 96. The dust cup module 80 includes a filter 83. After the mixture of debris and airflow from the first cleaning module 41 or the second cleaning module 42 enters the lower receiving cavity 96, it is filtered and separated by the filter 83. The debris falls downwards under gravity and accumulates at the bottom of the lower receiving cavity 96. The airflow flows through the filter 83, moves upwards from inside the filter 83, passes through the extension cover 82, and enters the motor 70 of the upper housing 20. The extension cover 82 connects the dust cup module 80 and the motor 70, functioning as part of the airflow passage.

[0139] Furthermore, referring to Figure 12 , Figure 13 , Figure 14 , Figure 15 The handle assembly 60 also includes an elastic reset member 62, which is connected to the handle 61 and the extension cover 82 respectively. The elastic reset member 62 is used to always apply an elastic force to the handle 61 to make the handle 61 stand up.

[0140] With this configuration, when the upper body 20 and lower body 50 are in the second state, the handle 61 can always be in an upright state under the action of the elastic reset member 62, making it convenient for the operator to grip. In the first state, the upper body 20 presses against the handle 61 so that the handle 61 is housed in the handle receiving cavity 94.

[0141] Furthermore, the handle 61 is rotatably connected to the extension cover 82 about the first axis O1, and the elastic reset member 62 is connected to the handle 61 and the extension cover 82 respectively, and is used to apply a rotational force about the first axis O1 to the handle 61.

[0142] In this way, when the upper body 20 and the lower body 50 are in the second state, the handle 61 can always be in the erected state under the rotation force of the elastic return member 62 around the first axis O1, which is convenient for the operator to grasp.

[0143] In a specific implementation, the elastic return member 62 can be a torsion spring. The handle 61 is in a semi-ring shape as a whole, and the two ends of the handle 61 are connected to the opposite sides of the extension cover 82 through an elastic return member 62 respectively. In this way, the handle 61 can be conveniently accommodated in the ring-shaped handle accommodating cavity 94.

[0144] In the embodiments of the present application, continuing to refer to Figure 13 , Figure 14 , Figure 15 , the end of the handle 61 is provided with a rotating connection part 611, the rotating connection part 611 extends towards the extension cover 82 and penetrates the extension cover 82, and the elastic return member 62 is sleeved outside the rotating connection part 611. The end of the handle 61 is provided with a clamping groove 612, one end of the elastic return member 62 is clamped in the clamping groove 612, and the other end of the elastic return member 62 is connected to the extension cover 82.

[0145] In this way, the elastic return member 62 can be reliably connected between the handle 61 and the extension cover 82. In addition, a limiting ring 613 is further arranged on the circumferential outer side of the rotating connection part 611, and a stop ring 821 is further arranged on the extension cover 82 at a position corresponding to the limiting ring 613, and the stop ring 821 is located on the circumferential outer side of the limiting ring 613. When the handle 61 rotates relative to the extension cover 82, the stop ring 821 is blocked on the circumferential outer side of the limiting ring 613, which can limit the rotation of the limiting ring 613. The clamping groove 612 can be arranged on the limiting ring 613.

[0146] Further, the end of the handle 61 is provided with a first stop part 63, and the bottom wall of the handle accommodating cavity 94 is provided with a second stop part 64 at a position corresponding to the first stop part 63. When the handle 61 is erected, the second stop part 64 is arranged on the front side of the rotating direction of the first stop part 63, so as to limit the rotation of the handle 61.

[0147] In this way, the handle 61 can be kept in the erected state and will not rotate into the handle accommodating cavity 94 again.

[0148] In the embodiments of the present application, in combination with Figure 11 , the open end of the upper shell 21 is further connected with a first pressing member 26, the first pressing member 26 is arranged at a position corresponding to the handle accommodating cavity 94, and in the first state, the first pressing member 26 presses against the handle 61, so as to overcome the elastic force of the elastic return member 62 and limit the handle 61 in the handle accommodating cavity 94.

[0149] In this way, in the first state, the handle 61 can be accommodated in the handle accommodating cavity 94, and in the second state, the handle 61 is erected under the elastic force of the elastic reset member 62.

[0150] Further, as mentioned above, the rotation axis of the handle 61 relative to the extension cover 82 is defined as the first axis. The second cleaning module 42 is rotationally connected to the lower body 50 about the second axis. In the second state, the upper body 20 is pivoted relative to the lower body 50 and located at the first side of the lower body 50. The first axis is located at the first side of the second axis.

[0151] In this way, the handle 61 is arranged closer to the gravity center of the cleaning device 100 in the second state, that is, closer to the gravity center of the whole machine. This arrangement makes it more labor-saving for the operator to pull.

[0152] The working process of the cleaning device 100 of the embodiment will be described below in combination with Figure 3 , Figure 4

[0153] In the first state, the second matching part 112 of the second pressing member 11 is clamped in the clamping groove 531 of the lower coupler 53, so that the upper body 20 and the lower body 50 are locked to each other and the first state is maintained. If the motor 70 is started, the suction force is provided, the garbage and airflow mixture enters the lower accommodating cavity 96 in the lower casing 51 through the first cleaning module 41 or the second cleaning module 42, is filtered and separated by the filter 83 in the lower accommodating cavity 96, and falls downward under the action of gravity and is accumulated at the bottom of the lower accommodating cavity 96. The airflow flows through the filter 83, moves upward from the inside of the filter 83, passes through the inside of the extension cover 82, and enters the first filtering cavity 91 of the upper body 20. The airflow filtered by the first filtering member 221 enters the motor 70 through the inlet of the motor 70. The gas in the motor 70 is filtered by the second filtering member 222 and discharged to the outside.

[0154] The operator operates the second pressing member 11 to release the clamping of the second matching part 112 and the lower coupler 53. At this time, the upper body 20 is rotated relative to the lower body 50, the upper coupler 23 and the lower coupler 53 are disconnected, and the inlet 910 of the first filtering cavity and the outlet 81 of the dust cup module are also fluidly disconnected, so as to switch the upper body 20 and the lower body 50 to the second state. At this time, the handle 61 is erected under the elastic force of the elastic reset member 62 for the operator to pull. Of course, in the state of long-distance transportation, boxing, etc., the second cleaning module 42 can also be detached to further reduce the size of the whole machine.

[0155] ​Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, as long as the combination of the technical features does not exist in contradiction, it shall be considered as within the scope of the present disclosure.

[0156] The above-described embodiments only express several implementation manners of the present application, the description is relatively specific and detailed, but it shall not be understood as a limitation on the scope of the present application patent. It should be pointed out that, for ordinary skilled in the art, under the premise of not departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
