[0034] Example embodiments now will be described more fully hereinafter with reference to the accompanying drawings; however, these embodiments can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the example embodiments to those skilled in the art. Like reference numerals refer to like elements throughout the drawings, and thus description of the same will be simplified and omitted.

[0035] Although relative terms such as "upper", "lower", etc. are used herein to describe one component's relationship to another component in the drawings, these terms are used herein for convenience only and are not to be construed as limiting the scope of the example embodiments. It is understood that if a device were turned over, the component described as being on top would then be on the bottom. When a structure is on another structure, it can mean that the structure is formed integrally with the other structure, or that the structure is "directly" on the other structure, or that the structure is "indirectly" on the other structure via another structure.

[0036] The terms "one", "a", "an", "the", and "at least one" are used to mean that "one or more" of something is present; the term "or" is used to mean "and / or" both; the term "includes" and its derivatives are used synonymously with "comprising"; the term "first", "second", and the like are used to connote "one or more than one", "two or more than two", and the like; the term "another" is used to mean "one or more than one of the previous items listed".

[0037] In the related art, as Figure 1As shown, the main door plate of the dust collecting device of the vacuum cleaner is designed as a flip door, the main structure 10' of the dust collecting device is designed with a dust cavity and an accessory storage area isolated from each other, the flip door 20' can take out the accessory brush head and dust bag of the vacuum cleaner when the door is opened, and the dust cavity is provided with a sealing strip around, the flip door 20' is designed with a profiled rib position corresponding to the sealing strip, and when the flip door 20' is closed, the rib position on the flip door 20' is pressed on the sealing strip of the dust cavity support to seal and ensure the negative pressure of dust collection. In the case that the dust collecting device is designed as Figure 2 As shown, in the case that the appearance has no protruding rotating shaft, when the conventional rotating shaft rotating structure is used, the sealing strip is close to the main body shell of the vacuum cleaner, and the sealing rib position on the flip door 20' interferes with the main structure 10' of the dust collecting device at position A when the flip door 20' is opened and closed, so the sealing strip needs to be a certain distance away from the shell of the dust collecting device to prevent the sealing rib position on the flip door 20' from rotating with the rib position structure bearing the sealing ring when the flip door 20' is opened and closed.

[0038] At present, the common solution is to move the sealing strip inward to increase the rotating radius of the rotating shaft and leave enough rotating space for the sealing rib position of the flip door. However, the distance between the sealing strip and the shell of the vacuum cleaner will inevitably compress the dust bag space, reduce the dust collecting capacity, and thus reduce the space utilization.

[0039] The disclosure embodiment provides a rotating mechanism, as shown in Figure 3 The rotating mechanism includes a first connecting piece 310, a second connecting piece 320, a first shell piece 20 and a second shell piece 10, the first connecting piece 310 and the second connecting piece 320 are rotationally connected, and the first shell piece 20 and the second shell piece 10 cooperate to form an accommodation space. Wherein, the first shell piece 20 is movably connected with the first connecting piece 310 to move towards or away from each other, the second shell piece 10 is connected with the second connecting piece 320; or the second shell piece 10 is movably connected with the second connecting piece 320 to move towards or away from each other, the first shell piece 20 is connected with the first connecting piece 310; or the first shell piece 20 is movably connected with the first connecting piece 310 to move towards or away from each other, the second shell piece 10 is movably connected with the second connecting piece 320 to move towards or away from each other.

[0040] The rotating mechanism provided by the present disclosure, the first connecting piece 310 is rotatably connected with the second connecting piece 320, the first shell piece 20 is connected with the first connecting piece 310, the second shell piece 10 is connected with the second connecting piece 320, the first shell piece 20 and the second shell piece 10 can rotate through the rotating assembly 30, for example, open and close action; when the second shell piece 10 rotates relative to the first shell piece 20, the first shell piece 20 and the first connecting piece 310 can move towards or away from each other and / or the second shell piece 10 and the second connecting piece 320 can move towards or away from each other, that is, the first shell piece 20 and the second shell piece 10 can move towards or away from each other, so that the first shell piece 20 and the second shell piece 10 adopt the design of no protruding rotating shaft in appearance, which is equivalent to setting a floating rotating assembly 30 between the first shell piece 20 and the second shell piece 10, so that the sealing strip to be set can be closely attached to the rotating position of the first shell piece 20 and the second shell piece 10, without reserving a certain distance, improving the utilization rate of the accommodation space, and at the same time improving the utilization rate of the accommodation space, the first shell piece 20 and the second shell piece 10 are set to be flat without rotating shaft structure profile at the rotating assembly 30, and the appearance design aesthetics of the rotating mechanism is improved.

[0041] In some embodiments, as shown in Figure 3 The rotating mechanism further comprises a rotating shaft 330, and the first connecting piece 310 and the second connecting piece 320 are rotatably connected through the rotating shaft 330. The rotating shaft holes can be respectively arranged on the first connecting piece 310 and the second connecting piece 320, the rotating shaft holes on the first connecting piece 310 and the second connecting piece 320 are aligned, then the rotating shaft 330 is inserted into the rotating shaft holes of the first connecting piece 310 and the second connecting piece 320 at the same time, so as to realize the rotatable connection of the first connecting piece 310 and the second connecting piece 320.

[0042] When the second shell piece 10 rotates relative to the first shell piece 20, the first shell piece 20 and the first connecting piece 310 can move towards or away from each other and / or the second shell piece 10 and the second connecting piece 320 can move towards or away from each other, that is, a floating rotating shaft is set between the first shell piece 20 and the second shell piece 10.

[0043] In some embodiments, the first connector 310 and the second connector 320 can be connected together by a snap-fit ​​connection to achieve rotation. For example, a snap-fit ​​groove is formed on the first connector 310, and a snap-fit ​​protrusion is formed on the second connector 320. The snap-fit ​​protrusion cooperates with the snap-fit ​​groove to connect the first connector 310 and the second connector 320. At the same time, the protrusion structure on the snap-fit ​​protrusion cooperates with the groove structure on the snap-fit ​​groove to achieve a rotational limit between the first connector 310 and the second connector 320. Of course, those skilled in the art may also use other structures to achieve the rotational connection between the first connector 310 and the second connector 320, and this disclosure is not limited thereto.

[0044] In some embodiments, the first connecting member 310 and the second connecting member 320 are detachably connected to facilitate assembly and disassembly of the rotating mechanism and improve the convenience of maintenance. Of course, the first connecting member 310 and the second connecting member 320 can also be connected in an undetachable manner, and this disclosure does not limit this.

[0045] In some embodiments, the first connecting member 310 is connected to the first shell member 20 through a first elastic member 340; or, the second connecting member 320 is connected to the second shell member 10 through a second elastic member; or, the first connecting member 310 is connected to the first shell member 20 through the first elastic member 340, and the second connecting member 320 is connected to the second shell member 10 through a second elastic member.

[0046] By connecting the first connecting member 310 and the first housing member 20 via the first elastic member 340, the first housing member 20 and the first connecting member 310 can move toward or away from each other through compression or extension of the first elastic member 340. When the second housing member 10 rotates relative to the first housing member 20, the first elastic member 340 can be stretched by an external force, causing the second housing member 10 to move away from the first housing member 20 at the location of the rotation axis 330, thereby preventing the structures on the first housing member 20 and the second housing member 10 from interfering with each other and being unable to pivot. Similarly, by connecting the second connecting member 320 and the second housing member 10 via the second elastic member, the first housing member 20 and the second connecting member 320 can move toward or away from each other through compression or extension of the second elastic member. When the second housing member 10 rotates relative to the first housing member 20, the second elastic member can be stretched by an external force so that the second housing member 10 moves away from the first housing member 20 at the position of the rotating shaft 330, thereby preventing the structures on the first housing member 20 and the structures on the second housing member 10 from interfering with each other and being unable to pivot.

[0047] Among them, when the second connecting member 320 is connected to the second shell member 10 through the second elastic member, the rotating shaft 330, and the rotating shaft 330 is located at the edge of the second shell member 10 or extends outward beyond the edge, so as to avoid the second connecting member 320 being obstructed by the first shell member 20 during the rotation process when the second shell member 10 is opened, so that the first shell member 20 can be opened to at least 90° relative to the second connecting member 320; during the rotation process after the second shell member 10 is opened relative to the first shell member 20, if the first shell member 20 and the second connecting member 320 contact and abut against each other, the abutment point can be used as an auxiliary fulcrum for applying force; thereby, when the second shell member 10 is closed relative to the first shell member 20, a flat, shaft-free structural profile can be set at the rotating component 30.

[0048] Specifically, when the second connecting member 320 is connected to the second housing member 10 via the second elastic member, relative movement between the second connecting member 320 and the second housing member 10 is limited to the extension and compression directions of the second elastic member. When the second housing member 10 is stretched to its maximum extension by stretching the second elastic member, the second housing member 10 remains rigidly connected to the second connecting member 320 in other directions, thereby preventing the second connecting member 320 from falling out of the guide portion of the second housing member 10. Similarly, when the first connecting member 310 is connected to the first housing member 20 via the first elastic member 340, relative movement between the first connecting member 310 and the first housing member 20 is limited to the extension and compression directions of the first elastic member 340. When the first housing member 20 is stretched to its maximum extension by stretching the first elastic member 340, the first housing member 20 remains rigidly connected to the first connecting member 310 in other directions, thereby preventing the first connecting member 310 from falling out of the guide portion of the first housing member 20.

[0049] The first elastic member 340 is a tension spring, the second elastic member is a tension spring, or both the first elastic member 340 and the second elastic member are tension springs. The tension spring structure is stable, highly reliable, and provides a relatively linear elastic force. Of course, the first elastic member 340 and the second elastic member can also be elastic rubber members or other elastic members capable of stretching and compressing, and this disclosure is not limited thereto.

[0050] Among them, when a first elastic member 340 and a second elastic member are provided at the same time, the types of the first elastic member 340 and the second elastic member can be the same, for example, both are tension springs; of course, the types of the first elastic member 340 and the second elastic member can also be different, and the present disclosure does not limit this.

[0051] In some embodiments, as Figure 3 As shown, the first housing 20 and the first connecting member 310 are elastically connected via the first elastic member 340 , the second housing 10 and the second connecting member 320 are fixedly connected, and the first connecting member 310 and the second connecting member 320 are rotatably connected via the rotating shaft 330 .

[0052] As shown in Figure 4 When the second shell part 10 is located at the closed position relative to the first shell part 20, the rotating assembly 30 is located at one side of the first shell part 20, one side of the second shell part 10 is rotationally connected with the first shell part 20 through the rotating assembly 30, and the other side of the second shell part 10 can be connected with the first shell part 20 through a door lock or a buckle to realize that the second shell part 10 is located at the closed position relative to the first shell part 20. Meanwhile, when the second shell part 10 is located at the closed position relative to the first shell part 20, the first elastic member 340 is located at the stretched state, that is, the first elastic member 340 can exert a pulling force on the first connecting member 310 towards the side of the first shell part 20 through the elastic restoring force of itself, so that the second shell part 10 can be tightly combined with the first shell part 20; when a sealing member is arranged between the second shell part 10 and the first shell part 20, the sealing member can be tightly clamped between the second shell part 10 and the first shell part 20 to improve the sealing effect.

[0053] As shown in Figure 5 When the second shell part 10 is located at the open position relative to the first shell part 20, the first elastic member 340 can be elongated by overcoming the elastic force of the first elastic member 340 through the applied external force, so that the first connecting member 310 moves away from the first shell part 20, and then the second shell part 10 moves away from the first shell part 20, thereby avoiding the interference between the structure on the second shell part 10 and the structure on the first shell part 20.

[0054] In some embodiments, the first connecting member 310 and the first shell part 20 can be movably connected through the plug-in mode to be able to move towards or away from each other; for example, one of the first connecting member 310 and the first shell part 20 is provided with a plug hole, and the other is provided with a plug rod, which can be fitted through the plug rod and the plug hole to realize the relative movement between the first connecting member 310 and the first shell part 20 in the preset direction. Similarly, the second connecting member 320 and the second shell part 10 can also be movably connected through the plug-in mode to be able to move towards or away from each other; for example, one of the second connecting member 320 and the second shell part 10 is provided with a plug hole, and the other is provided with a plug rod, which can be fitted through the plug rod and the plug hole to realize the relative movement between the second connecting member 320 and the second shell part 10 in the preset direction.

[0055] In some embodiments, the first shell part 20 is provided with a first guide structure 210, and the first connecting member 310 moves towards or away from the first shell part 20 through the first guide structure 210; or the second shell part 10 is provided with a second guide structure, and the second connecting member 320 moves towards or away from the second shell part 10 through the second guide structure; or the first shell part 20 is provided with a first guide structure 210, and the first connecting member 310 moves towards or away from the first shell part 20 through the first guide structure 210, and the second shell part 10 is provided with a second guide structure, and the second connecting member 320 moves towards or away from the second shell part 10 through the second guide structure.

[0056] By forming the first guide structure 210 on the first shell part 20, the first connecting member 310 moves towards or away from the first shell part 20 through the first guide structure 210, which guides the movement of the first connecting member 310 relative to the first shell part 20, and improves the stability and reliability of the movement of the first connecting member 310 relative to the first shell part 20. Similarly, by forming the second guide structure on the second shell part 10, the second connecting member 320 moves towards or away from the second shell part 10 through the second guide structure, which guides the movement of the second connecting member 320 relative to the second shell part 10, and improves the stability and reliability of the movement of the second connecting member 320 relative to the second shell part 10.

[0057] In some embodiments, the first guide structure 210 includes a first guide groove, and at least part of the first connecting member 310 is located in the first guide groove; or the second guide structure includes a second guide groove, and at least part of the second connecting member 320 is located in the second guide groove; or the first guide structure 210 includes a first guide groove, and at least part of the first connecting member 310 is located in the first guide groove, and the second guide structure includes a second guide groove, and at least part of the second connecting member 320 is located in the second guide groove.

[0058] By making the first guide structure 210 include a first guide groove, and at least part of the first connecting member 310 is located in the first guide groove, on the one hand, the first guide groove guides the movement of the first connecting member 310, and on the other hand, the first guide groove protects the first connecting member 310, avoiding the obstruction of sundries to the movement of the first connecting member 310 relative to the first shell part 20, and also shielding dust and sewage. Similarly, by making the second guide structure include a second guide groove, and at least part of the second connecting member 320 is located in the second guide groove, on the one hand, the second guide groove guides the movement of the second connecting member 320, and on the other hand, the second guide groove protects the second connecting member 320, avoiding the obstruction of sundries to the movement of the second connecting member 320 relative to the second shell part 10, and also shielding dust and sewage.

[0059] The first guiding structure 210 comprises a first guiding groove, and at least part of the first connecting member 310 is located in the first guiding groove. The shape and size of the first guiding groove match those of the first connecting member 310, for example, both are rectangular, so as to provide stable guiding effect and improve the connecting strength.

[0060] In some embodiments, the first elastic member 340 is located in the first guiding groove; or the second elastic member is located in the second guiding groove; or the first elastic member 340 is located in the first guiding groove, and the second elastic member is located in the second guiding groove.

[0061] By locating the first elastic member 340 in the first guiding groove, hidden assembly of the first elastic member 340 is formed, which avoids the obstruction of sundries to the first elastic member 340 and also forms a shield for dust and sewage, thereby ensuring the service life of the first elastic member 340. Similarly, by locating the second elastic member in the second guiding groove, hidden assembly of the second elastic member is formed, which avoids the obstruction of sundries to the second elastic member and also forms a shield for dust and sewage, thereby ensuring the service life of the second elastic member.

[0062] In some embodiments, the first connecting member 310 is detachably connected with the first shell member 20, or the second connecting member 320 is detachably connected with the second shell member 10. By detachably connecting the first connecting member 310 with the first shell member 20, the assembly and disassembly and maintenance of the first connecting member 310 and the first shell member 20 are facilitated, and the first connecting member 310 and the first shell member 20 are also facilitated to be manufactured by a mold. Similarly, by detachably connecting the second connecting member 320 with the second shell member 10, the assembly and disassembly and maintenance of the second connecting member 320 and the second shell member 10 are facilitated, and the second connecting member 320 and the second shell member 10 are also facilitated to be manufactured by a mold.

[0063] When one side between the first connecting member 310 and the first shell member 20 is inelastic, the first connecting member 310 and the first shell member 20 can be detachably connected by screw connection or clamping. When one side between the second connecting member 320 and the second shell member 10 is inelastic, the second connecting member 320 and the second shell member 10 can be detachably connected by screw connection or clamping.

[0064] As Figure 3As shown, the second connecting piece 320 is detachably connected with the second housing piece 10, the second housing piece 10 is provided with a mounting groove 110, the second connecting piece 320 is first inserted into the mounting groove 110, and then the second connecting piece 320 is fixed on the second housing piece 10 through screws. Through the setting of the mounting groove 110, on the one hand, the connection stability between the second connecting piece 320 and the second housing piece 10 is improved, and on the other hand, the second connecting piece 320 is shielded, so that when the second connecting piece 320 is made of metal or other materials, the reliability is not reduced due to corrosion or oxidation of sewage.

[0065] In some embodiments, the first connecting piece 310 and the second connecting piece 320 are located on the same side of the first housing piece 20 and the second housing piece 10 in the thickness direction. Figure 6 As shown, by locating the first connecting piece 310 and the second connecting piece 320 on the same side of the first housing piece 20 and the second housing piece 10 in the thickness direction, the first housing piece 20 and the second housing piece 10 can be provided with a flat and non-rotating shaft structure profile at the rotating structure, and the appearance design aesthetics of the rotating mechanism is improved.

[0066] The embodiments of the present disclosure also provide a dust collecting device, which comprises the rotating mechanism described in the above embodiments. Figure 7 As shown, the first housing piece 20 is the main body shell of the dust collecting device, the second housing piece 10 is the door plate of the dust collecting device, and the door plate is rotatably connected with the main body shell through the rotating assembly 30.

[0067] When the door plate rotates relative to the main body shell, the main body shell and the first connecting piece can move towards or away from each other and / or the door plate and the second connecting piece can move towards or away from each other, i.e. the door plate and the main body shell can move towards or away from each other, so that when the main body shell and the door plate adopt the design of no protruding rotating shaft in appearance, a floating rotating assembly is equivalent to being arranged between the main body shell and the door plate; when the door plate is opened or closed, the door plate moves outward through the elastic piece, so that when the door plate is rotated and opened, the door plate will not be hindered from further opening due to interference with the main body shell or the main body structure, so that the sealing strip that needs to be arranged can be closely arranged at the rotating position of the main body shell and the door plate, without reserving a certain distance, thereby improving the space utilization rate, and a flat and non-rotating shaft structure profile can be arranged at the rotating structure of the main body shell and the door plate, thereby improving the appearance design aesthetics of the rotating mechanism; in addition, if the door plate abuts against the main body shell during opening, an auxiliary fulcrum for force application can be formed, and a user can stably open the door plate to a required angle by applying a force in the opening direction with one hand. In addition, more details of the rotating assembly arranged on the dust collecting device and the corresponding technical effects are described in detail in the above rotating mechanism, and will not be described here.

[0068] The embodiments of the present disclosure also provide a cleaning system, which comprises the cleaning device and the dust collecting device.

[0069] The cleaning device can be a handheld vacuum cleaner, which comprises a machine body, a dust cup, a negative pressure fan, a machine body extension tube and a cleaning brush head. Dust and sundries on the surface to be cleaned move upward along the cleaning brush head, the machine body extension tube and the air duct in the machine body under the action of the negative pressure fan, and finally enter the dust cup for storage. The dust collecting device comprises a dust collecting air duct, a dust bag and a negative pressure fan. The main function of the dust collecting device is to recover dust and sundries in the dust cup of the handheld vacuum cleaner. The specific working mode is as follows: after the handheld vacuum cleaner is placed on the dust collecting device, the door plate at the dust collecting port of the dust cup is opened under the action of the cooperation mechanism while the in-place switch of the vacuum cleaner is triggered. The dust cup is communicated with the dust bag through the dust collecting channel. At this time, the negative pressure fan of the dust collecting device starts to work. Dust and sundries in the dust cup enter the dust bag under the action of negative pressure in the dust collecting air duct, and the dust cup cleaning action is completed. When the vacuum cleaner is taken out, the door plate at the dust collecting port of the dust cup is closed under the action of the corresponding mechanism, so as to prevent dust and gas from leaking from the dust cup of the handheld vacuum cleaner.
