Rotating mechanism, dust collection device and cleaning system Cross-references to related applications

[0001] This disclosure claims priority to Chinese patent applications Nos. 202411629746.9 and 202422774968.1, filed on November 13, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of cleaning device technology, and more specifically, to a rotating mechanism, a dust collection device, and a cleaning system. Background Technology

[0003] With the continuous development of society, more and more people are focusing their lives on work, thus needing more time to rest and improve their quality of life. Vacuum cleaners are becoming an increasingly popular choice for families. Vacuum cleaners are common devices for cleaning dust from object surfaces, typically consisting of a fan, a separator, and a dust cup, with the separator located inside the dust cup. When the vacuum cleaner is working, the dust is separated by the separator under the force of the fan, and most of the dust is collected in the dust cup. Although some handheld vacuum cleaners have an openable bottom for the dust cup, dust has a strong adsorption capacity, necessitating a dust collection device to recover the dust from the dust cup. Therefore, users are placing increasingly higher demands on dust collection devices.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0034] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0035] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0036] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” etc. are used only as markers and are not a limitation on the number of objects.

[0037] In related technologies, as shown in Figure 1, the main door panel of the vacuum cleaner's dust collection device is a flip-top door design. The main structure 10' of the dust collection device is designed with mutually isolated dust chambers and accessory storage areas. When the flip-top door 20' is opened, the vacuum cleaner's accessory brush head and dust bag can be taken out. A sealing strip is provided around the dust chamber. The flip-top door 20' has contoured ribs at the corresponding positions of the sealing strips. When the flip-top door 20' is closed, the ribs press against the sealing strip of the dust chamber support to seal and ensure negative pressure during dust collection. In the case where the dust collection device is designed without a protruding rotating shaft as shown in Figure 2, when using a traditional rotating shaft structure, the sealing strip is close to the vacuum cleaner's main body shell. When the flip-top door 20' opens and closes, the sealing ribs on the flip-top door 20' interfere with the main structure 10' of the dust collection device at position A. Therefore, the sealing strip needs to be a certain distance from the outer shell of the dust collection device to prevent rotational interference between the sealing ribs on the flip-top door 20' and the rib structure supporting the sealing ring when the flip-top door 20' opens and closes.

[0038] Currently, a common solution is to move the sealing strip inward to increase the rotation radius of the pivot and provide sufficient rotation space for the sealing ribs of the flip door. However, leaving a certain distance between the sealing strip and the vacuum cleaner casing will inevitably compress the dust bag space, reducing the dust collection capacity and thus lowering space utilization.

[0039] This disclosure provides a rotating mechanism. As shown in FIG3, the rotating mechanism includes: a first connecting member 310, a second connecting member 320, a first housing member 20, and a second housing member 10, wherein the first connecting member 310 and the second connecting member 320 are rotatably connected. Specifically, the first housing member 20 is movably connected to the first connecting member 310 to move towards or away from each other, and the second housing member 10 is connected to the second connecting member 320; or the second housing member 10 is movably connected to the second connecting member 320 to move towards or away from each other, and the first housing member 20 is connected to the first connecting member 310; or the first housing member 20 is movably connected to the first connecting member 310 to move towards or away from each other, and the second housing member 10 is movably connected to the second connecting member 320 to move towards or away from each other.

[0040] The rotating mechanism disclosed herein includes a first connecting member 310 rotatably connected to a second connecting member 320, a first housing member 20 connected to the first connecting member 310, and a second housing member 10 connected to the second connecting member 320. The first housing member 20 and the second housing member 10 can rotate relative to each other via a rotating assembly 30, for example, performing opening and closing actions. When the second housing member 10 rotates relative to the first housing member 20, the first housing member 20 and the first connecting member 310 can move towards or away from each other, and / or the second housing member 10 and the second connecting member 320 can move towards or away from each other, i.e., the first housing member 20 can rotate relative to the first housing member 20. The first housing 20 and the second housing 10 move towards or away from each other, so that the first housing 20 and the second housing 10 adopt a design without a protruding rotating shaft. This is equivalent to setting a floating rotating component 30 between the first housing 20 and the second housing 10. This allows the sealing strip that needs to be set to be close to the rotating position of the first housing 20 and the second housing 10 without leaving a certain distance, thus improving the space utilization. In addition to improving the space utilization, the first housing 20 and the second housing 10 can also have a flat, shaftless structural outline at the location where the rotating component 30 is set, which enhances the aesthetic design of the rotating mechanism.

[0041] In some embodiments, the first housing member 20 and the second housing member 10 cooperate to form an accommodating space. The rotating mechanism with the above-described structure provided in this disclosure improves the utilization rate of the accommodating space. While improving the utilization rate of the accommodating space, it also enables the first housing member 20 and the second housing member 10 to have a flat, shaftless structural outline at the location where the rotating component 30 is provided, thereby enhancing the aesthetic design of the rotating mechanism.

[0042] In some embodiments, as shown in FIG3, the rotating mechanism further includes a rotating shaft 330, through which the first connecting member 310 and the second connecting member 320 are rotatably connected. The first connecting member 310 and the second connecting member 320 may each be provided with a rotating shaft hole. After aligning the rotating shaft holes on the first connecting member 310 and the second connecting member 320, the rotating shaft 330 is simultaneously inserted into the rotating shaft holes of both the first connecting member 310 and the second connecting member 320 to achieve a rotatable connection between the first connecting member 310 and the second connecting member 320.

[0043] When the second housing component 10 rotates relative to the first housing component 20, the first housing component 20 and the first connecting member 310 can move towards each other or away from each other, and / or the second housing component 10 and the second connecting member 320 can move towards each other or away from each other, which is equivalent to a floating rotating shaft being provided between the first housing component 20 and the second housing component 10.

[0044] In some embodiments, the first connector 310 and the second connector 320 can be connected together by a snap-fit ​​mechanism to achieve rotation. For example, the first connector 310 has a slot, and the second connector 320 has a protrusion. The engagement of the protrusion and the slot connects the first connector 310 and the second connector 320 together. Simultaneously, the engagement of the protrusion on the protrusion and the groove on the slot limits the rotation between the first connector 310 and the second connector 320. Of course, those skilled in the art can use other structures to achieve the rotational connection between the first connector 310 and the second connector 320, and this disclosure does not impose any limitations on this.

[0045] In some embodiments, the first connector 310 and the second connector 320 are detachably connected, facilitating the installation and removal of the rotating mechanism and improving maintenance convenience. Of course, the first connector 310 and the second connector 320 may also be connected without detachment, and this disclosure does not limit this.

[0046] In some embodiments, the first connector 310 is connected to the first housing 20 via a first elastic member 340; or, the second connector 320 is connected to the second housing 10 via a second elastic member; or, the first connector 310 is connected to the first housing 20 via a first elastic member 340, and the second connector 320 is connected to the second housing 10 via a second elastic member.

[0047] By connecting the first connecting member 310 to the first housing member 20 via the first elastic member 340, the first housing member 20 and the first connecting member 310 can move towards or away from each other through compression or tension 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 position of the pivot 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. Similarly, by connecting the second connecting member 320 to the second housing member 10 via the second elastic member, the first housing member 20 and the second connecting member 320 can move towards or away from each other through compression or tension of the second elastic member. When the second housing 10 rotates relative to the first housing 20, the second elastic member can be stretched by an external force so that the second housing 10 moves away from the first housing 20 at the position of the pivot 330, thereby preventing the structure on the first housing 20 from being unable to pivot due to mutual interference and jamming.

[0048] When the second connector 320 is connected to the second housing 10 via the second elastic member, the pivot 330 is located at the edge of the second housing 10 or extends outward beyond the edge to prevent the second connector 320 from being obstructed by the first housing 20 during rotation when the second housing 10 is opened, so that the first housing 20 can be opened to at least 90° relative to the second connector 320. During the rotation of the second housing 10 after it is opened relative to the first housing 20, if the first housing 20 and the second connector 320 come into contact and abut, the abutment point can serve as an auxiliary fulcrum for applying force. Thus, when the second housing 10 is closed relative to the first housing 20, a flat, pivotless structural profile can be provided at the rotating assembly 30.

[0049] When the second connector 320 is connected to the second housing 10 via the second elastic member, the second connector 320 and the second housing 10 can only move relative to each other in the tensile and compressive directions of the second elastic member. When the second housing 10 is stretched to its maximum tensile state by stretching the second elastic member, the second housing 10 still maintains a rigid connection with the second connector 320 in other directions, thereby preventing the second connector 320 from dislodging from the guide portion on the second housing 10. Similarly, when the first connector 310 is connected to the first housing 20 via the first elastic member 340, the first connector 310 and the first housing 20 can only move relative to each other in the tensile and compressive directions of the first elastic member 340. When the first housing 20 is stretched to its maximum tensile state by stretching the first elastic member 340, the first housing 20 still maintains a rigid connection with the first connector 310 in other directions, thereby preventing the first connector 310 from dislodging from the guide portion on the first housing 20.

[0050] The first elastic element 340 is a tension spring, or the second elastic element is a tension spring, or both the first elastic element 340 and the second elastic element are tension springs. Tension springs have a stable structure, high reliability, and provide a relatively linear elastic force. Of course, the first elastic element 340 and the second elastic element can also be elastic rubber elements or other elastic elements capable of stretching and compression; this disclosure does not impose any limitations on this.

[0051] When both a first elastic element 340 and a second elastic element are provided, the types of the first elastic element 340 and the second elastic element can be the same, for example, both can be tension springs; of course, the types of the first elastic element 340 and the second elastic element can also be different, and this disclosure does not impose any restrictions on this.

[0052] In some embodiments, as shown in FIG3, the first housing 20 and the first connector 310 are elastically connected by the first elastic member 340, the second housing 10 and the second connector 320 are fixedly connected, and the first connector 310 and the second connector 320 are rotatably connected by the rotating shaft 330.

[0053] As shown in Figure 4, when the second housing component 10 is in the closed position relative to the first housing component 20, the rotating assembly 30 is located on one side of the first housing component 20. One side of the second housing component 10 is rotatably connected to the first housing component 20 through the rotating assembly 30, and the other side of the second housing component 10 can be connected to the first housing component 20 through a door lock or buckle, so that the second housing component 10 is in the closed position relative to the first housing component 20. At the same time, when the second housing component 10 is in the closed position relative to the first housing component 20, the first elastic component 340 is in a stretched state, that is, the first elastic component 340 can apply a pulling force towards the first connecting component 310 towards the first housing component 20 through its own elastic restoring force, so that the second housing component 10 can be tightly combined with the first housing component 20. When a sealing component is provided between the second housing component 10 and the first housing component 20, the sealing component can be tightly clamped between the second housing component 10 and the first housing component 20 to improve the sealing effect.

[0054] As shown in Figure 5, when the second housing member 10 is in the open position relative to the first housing member 20, the applied external force can overcome the elastic force of the first elastic member 340 and stretch it, thereby causing the first connecting member 310 to move away from the first housing member 20, and thus causing the second housing member 10 to move away from the first housing member 20, thereby avoiding interference between the structure on the second housing member 10 and the structure on the first housing member 20.

[0055] In some embodiments, the first connector 310 and the first housing 20 can be movably connected by a plug-in connection to enable relative movement towards or away from each other. For example, one of the first connector 310 and the first housing 20 may have a socket, and the other may have a rod. The rod can be press-fitted with the socket to allow relative movement between the first connector 310 and the first housing 20 in a predetermined direction. Similarly, the second connector 320 and the second housing 10 can also be movably connected by a plug-in connection to enable relative movement towards or away from each other. For example, one of the second connector 320 and the second housing 10 may have a socket, and the other may have a rod. The rod can be press-fitted with the socket to allow relative movement between the second connector 320 and the second housing 10 in a predetermined direction.

[0056] In some embodiments, a first guide structure 210 is formed on the first housing member 20, and the first connector 310 moves toward or away from the first housing member 20 through the first guide structure 210; or, a second guide structure is formed on the second housing member 10, and the second connector 320 moves toward or away from the second housing member 10 through the second guide structure; or, a first guide structure 210 is formed on the first housing member 20, the first connector 310 moves toward or away from the first housing member 20 through the first guide structure 210, and a second guide structure is formed on the second housing member 10, and the second connector 320 moves toward or away from the second housing member 10 through the second guide structure.

[0057] By forming a first guide structure 210 on the first housing member 20, the first connecting member 310 moves towards or away from the first housing member 20 via the first guide structure 210, thus guiding the movement of the first connecting member 310 relative to the first housing member 20 and improving the stability and reliability of the movement of the first connecting member 310 relative to the first housing member 20. Similarly, by forming a second guide structure on the second housing member 10, the second connecting member 320 moves towards or away from the second housing member 10 via the second guide structure, thus guiding the movement of the second connecting member 320 relative to the second housing member 10 and improving the stability and reliability of the movement of the second connecting member 320 relative to the second housing member 10.

[0058] In some embodiments, the first guide structure 210 includes a first guide groove, and at least a portion of the first connector 310 is located in the first guide groove; or, the second guide structure includes a second guide groove, and at least a portion of the second connector 320 is located in the second guide groove; or, the first guide structure 210 includes a first guide groove, at least a portion of the first connector 310 is located in the first guide groove, and the second guide structure includes a second guide groove, and at least a portion of the second connector 320 is located in the second guide groove.

[0059] By including a first guide groove in the first guide structure 210, at least a portion of the first connector 310 is located within the first guide groove. This provides guidance for the movement of the first connector 310 and also protects it from debris, preventing obstruction of movement relative to the first housing member 20. Additionally, it provides protection against dust and wastewater. Similarly, by including a second guide groove in the second guide structure, at least a portion of the second connector 320 is located within the second guide groove. This provides guidance for the movement of the second connector 320 and also protects it from debris, preventing obstruction of movement relative to the second housing member 10. Additionally, it provides protection against dust and wastewater.

[0060] The first guide structure 210 includes a first guide groove, at least a portion of the first connector 310 is located in the first guide groove, and the shape and size of the first guide groove match the shape and size of the first connector 310, for example, both are rectangular, to provide a stable guiding effect and improve the reliability of the connection strength.

[0061] In some embodiments, the first elastic member 340 is located in the first guide groove; or, the second elastic member is located in the second guide groove; or, the first elastic member 340 is located in the first guide groove and the second elastic member is located in the second guide groove.

[0062] By positioning the first elastic element 340 within the first guide groove, a concealed assembly of the first elastic element 340 is achieved, preventing debris from obstructing its movement and also shielding it from dust and wastewater, thus extending its lifespan. Similarly, by positioning the second elastic element within the second guide groove, a concealed assembly of the second elastic element is achieved, preventing debris from obstructing its movement and also shielding it from dust and wastewater, thus extending its lifespan.

[0063] In some embodiments, the first connector 310 is detachably connected to the first housing 20, or the second connector 320 is detachably connected to the second housing 10. Detachable connection between the first connector 310 and the first housing 20 facilitates their assembly, disassembly, and maintenance, and also facilitates manufacturing using molds. Similarly, detachable connection between the second connector 320 and the second housing 10 facilitates their assembly, disassembly, and maintenance, and also facilitates manufacturing using molds.

[0064] When the first connector 310 and the first housing 20 are on the side that cannot move elastically, the first connector 310 and the first housing 20 can be detachably connected by means of threaded connection or snap-fit; when the second connector 320 and the second housing 10 are on the side that cannot move elastically, the second connector 320 and the second housing 10 can be detachably connected by means of threaded connection or snap-fit.

[0065] As shown in Figure 3, the second connector 320 is detachably connected to the second housing 10. The second housing 10 has a mounting groove 110. The second connector 320 first extends into the mounting groove 110, and then is fixed to the second housing 10 with screws. The mounting groove 110 improves the connection stability between the second connector 320 and the second housing 10, and also shields the second connector 320, preventing it from being corroded or oxidized by sewage or other substances when made of metal, thus avoiding a decrease in reliability.

[0066] In some embodiments, the first connector 310 and the second connector 320 are located on the same side in the thickness direction of the first housing member 20 and the second housing member 10. As shown in FIG6, by positioning the first connector 310 and the second connector 320 on the same side in the thickness direction of the first housing member 20 and the second housing member 10, the first housing member 20 and the second housing member 10 can be provided with a flat, shaftless structural profile at the rotating structure, thereby improving the aesthetic design of the rotating mechanism.

[0067] The embodiments of this disclosure also provide a dust collection device, which includes the rotating mechanism described in the above embodiments. As shown in FIG7, the first housing component 20 is the main outer shell of the dust collection device, and the second housing component 10 is the door panel of the dust collection device. The door panel is rotatably connected to the main outer shell through the rotating assembly 30.

[0068] When the door panel rotates relative to the main shell, the main shell and the first connecting member can move towards or away from each other, and / or the door panel and the second connecting member can move towards or away from each other. This allows the door panel and the main shell to move towards or away from each other. Thus, when the main shell and the door panel adopt a design without a protruding pivot, it is equivalent to setting a floating rotating component between the main shell and the door panel. When the door panel opens and closes, it moves outward through the elastic element, so that the door panel will not interfere with the main shell or the main structure when it rotates and opens, thus not hindering the further opening action of the door panel. This allows the sealing strip that needs to be installed to be close to the rotation position of the main shell and the door panel without leaving a certain distance, improving space utilization. At the same time, it can also create a flat, pivot-free structural outline at the rotation structure of the main shell and the door panel, enhancing the aesthetic design of the rotation mechanism. In addition, if the door panel abuts against the main shell during the opening process, it can form an auxiliary fulcrum for applying force, and the user can stably open the door panel to the required angle by applying force in the opening direction with only one hand. For more details on the rotating components installed on the dust collection device and their corresponding technical effects, please refer to the detailed discussion of the rotating mechanism mentioned above, which will not be repeated here.

[0069] Embodiments of this disclosure also provide a cleaning system, which includes cleaning equipment and the dust collection device described above.

[0070] The cleaning equipment can be a handheld vacuum cleaner, which includes a body, dust cup, negative pressure fan, extension tube, and cleaning brush head. Dust and debris on the surface to be cleaned move upwards along the cleaning brush head, extension tube, and internal air duct under the action of the negative pressure fan, eventually entering the dust cup for collection. The dust collection device includes a dust collection duct, dust bag, and negative pressure fan. The main function of the dust collection device is to collect dust and debris from the dust cup of the handheld vacuum cleaner. Specifically, when the handheld vacuum cleaner is placed on the dust collection device and the vacuum cleaner's positioning switch is triggered, the door at the dust cup's dust collection port opens under the action of a cooperating mechanism. The dust cup connects to the dust bag through the dust collection channel. At this time, the negative pressure fan of the dust collection device starts working, and the dust and debris in the dust cup enter the dust bag under the negative pressure in the dust collection duct, completing the dust cup cleaning process. When the vacuum cleaner is removed, the door at the dust cup's dust collection port closes under the action of a corresponding mechanism to prevent dust and air leakage from the dust cup when using the handheld vacuum cleaner.
