Description

[0001] The present application relates to the technical field of household cleaning appliance, and in particular to a handheld structure.

[0002] Cleaning appliances (such as vacuum cleaners, floor washers, etc.) can extract / suck dust, dirt and debris on the ground to keep the ground clean.

[0003] In the relevant art, a cleaning appliance has a handheld structure comprising a dust cup assembly and a main unit assembly detachably connected to a main body of the appliance. The main unit assembly and the dust cup assembly are usually connected by a snap locking structure. The main unit assembly is used to provide a suction force, while the dust cup assembly is used to collect sucked dust and debris.

[0004] However, the connection strength of a snap locking structure is weak, and it is easy to break and fail after long-term stress. As a result, the reliability of connection between a main unit assembly and a dust cup assembly that relies only on a snap locking structure is poor, and the service life is short.

[0005] Based on this, the present application provides a handheld structure to solve the problem of poor reliability and short service life of the connection between a main unit assembly and a dust cup assembly of a handheld structure.

[0006] The handheld structure provided by the present application comprises a mounting base, a main unit assembly and a dust cup assembly detachably connected to the main unit assembly, the mounting base comprising a mounting base body, a main unit connector and a dust cup connector, the main unit connector and the dust cup connector being both connected to the mounting base body, the main unit assembly being detachably connected to the main unit connector, the dust cup assembly being detachably connected to the dust cup connector.

[0007] The handheld structure provided by the present application, by providing a mounting base having a main unit connector and a dust cup connector, realizes connection between the main unit assembly and the mounting base by means of the main unit connector, and realizes connection between the dust cup assembly and the mounting base by means of the dust cup connector. In this way, on the basis of the detachable connection between the main unit assembly and the dust cup assembly, the main unit assembly and the dust cup assembly are further connected to each other through the mounting base by connecting the mounting base to the main unit assembly and the dust cup assembly respectively, thereby strengthening the reliability of connection between the main unit assembly and the dust cup assembly. In this way, a force at the connection between the main unit assembly and the dust cup assembly can be dispersed to the mounting base, reducing direct stress on the main unit assembly and the dust cup assembly, thereby improving the reliability of connection between the main unit assembly and the dust cup assembly, and extending the service life of the connection between the main unit assembly and the dust cup assembly.

[0008] In a possible mode of realization, the handheld structure provided by the present application further comprises a buckle assembly, the main unit assembly and the main unit connector being engaged with or disengaged from each other through the buckle assembly.

[0009] In this way, by providing a buckle assembly to realize detachable connection between the main unit assembly and the main unit connector, connection and disconnection between the main unit assembly and the main unit connector can be made more convenient and quicker, and the reliability of connection between the main unit assembly and the main unit connector can be improved to ensure that the connection between the main unit assembly and the dust cup assembly is stable and reliable.

[0010] In a possible mode of realization, the handheld structure provided by the present application further comprises a locking assembly, an end of the dust cup assembly facing away from the main unit assembly being engaged or disengaged by snap-fit with / from the dust cup connector through the locking assembly.

[0011] In this way, by providing a locking assembly to realize connection between the end of the dust cup assembly facing away from the main unit assembly and the dust cup connector, connection between the end of the dust cup assembly close to the main unit assembly and the main unit assembly can be facilitated, making the overall structure simpler and more compact, and ensuring that both ends of the dust cup assembly are connected and fixed. In addition, it helps ensure the reliability of connection between the dust cup assembly and the main unit assembly, and the mounting base.

[0012] In a possible mode of realization, the handheld structure provided by the present application has an air duct on the mounting base, and the dust cup assembly is provided with an air inlet, the air duct being in communication with the air inlet; the dust cup assembly is in communication with the main unit assembly; the main unit assembly is provided with a first air outlet, and the mounting base is provided with at least one second air outlet, the first air outlet being in communication with the second air outlet.

[0013] In this way, by providing the air duct and the second air outlet on the mounting base, connecting the air duct with the air inlet of the dust cup assembly, and connecting the second air outlet with the first air outlet of the main unit assembly, a complete air flow channel can be formed between the mounting base, the dust cup assembly and the main unit assembly, and the inlet and outlet of the air flow channel are both arranged on the mounting base. In this way, when the main unit assembly and the dust cup assembly are used separately alone relative to the main body of the handheld structure, the mounting base is subjected to the force in contact with a cleaning surface, avoiding direct force on the dust cup assembly and the main unit assembly, thereby improving the stability of connection between the main unit assembly and the dust cup assembly, and the mounting base, thus ensuring the stability and reliability of connection between the main unit assembly and the dust cup assembly. Moreover, compared with a situation where the air duct is directly arranged on the dust cup assembly, the air duct arranged on the mounting base is farther away from the main unit assembly, so as to reduce operating noise of the main unit assembly and the dust cup assembly when they are used separately alone, thereby improving user experience.

[0014] In a possible mode of realization, in the handheld structure provided by the present application, the main unit assembly comprises a main unit body and a main unit bottom cover, the main unit bottom cover is arranged on the main unit body and encloses a first accommodation cavity with the main unit body;

[0015] the main unit connector is arranged on the mounting base body and encloses a second accommodation cavity with the mounting base body; the buckle assembly is at least partially located in one of the first accommodation cavity and the second accommodation cavity, so as to engage or disengage by snap-fit with / from the main unit connector or the main unit bottom cover enclosing the other accommodation cavity.

[0016] In this way, by forming the first accommodation cavity on the main unit assembly and forming the second accommodation cavity on the mounting base, the buckle assembly can be arranged on the main unit assembly or the mounting base, and connected to the other, so as to ensure stable connection between the main unit assembly and the mounting base, and realize flexible arrangement of the buckle assembly on the one of the two that is more convenient for mounting and operation, thereby making the structure of the handheld structure more compact, and making connection and disconnection between the main unit assembly and the mounting base more convenient and quicker.

[0017] In a possible mode of realization, in the handheld structure provided by the present application, the buckle assembly comprises a buckle bracket and two first buckles both connected to the buckle bracket; the buckle bracket is configured to be partially located outside the second accommodation cavity, and to move in a first direction relative to the main unit bottom cover and drive the two first buckles to approach each other when being pushed or pulled by an external force, so that the first buckles both disengage from snap-fit with the main unit bottom cover.

[0018] In this way, by providing two first buckles both connected to the buckle bracket, movement of the two first buckles at the same time by pushing and pulling the buckle bracket is facilitated, so that the reliability of connection between the buckle assembly and the main unit assembly is high, disassembly operation is simpler and disassembly efficiency is high.

[0019] In a possible mode of realization, the handheld structure provided by the present application has a second buckle arranged on the buckle bracket, and a buckling slot matching the second buckle is provided on the main unit bottom cover; the second buckle is configured to move along with the buckle bracket and to engage or disengage by snap-fit with / from the buckling slot synchronously with and perpendicular to the first buckles.

[0020] In this way, by providing a second buckle on the buckle bracket, the second buckle can be used to further enhance the snap-fit between the buckle assembly and the main unit assembly on the basis of the two first buckles, thereby improving the reliability of connection between the main unit assembly and the mounting base.

[0021] In a possible mode of realization, in the handheld structure provided by the present application, the buckle assembly further comprises a first reset member, the main unit connector is provided with a first mounting portion, and the buckle bracket is provided with a second mounting portion, two ends of the first reset member being respectively sleeved on the first mounting portion and the second mounting portion; the first reset member is configured to be compressed and deformed when the buckle bracket moves toward a first direction under an action of an external force, so that the second buckle is unlocked from the buckling slot; and to drive the buckle bracket to move toward a second direction when the external force on the buckle bracket is released, so as to drive the second buckle to engage with the buckling slot, wherein the first direction is opposite to the second direction.

[0022] In this way, by providing the first reset member between the buckle bracket and the main unit connector, and using the first reset member to drive the buckle bracket to reset, the user experience of the buckle assembly can be improved, and the unlocking operation can be performed again.

[0023] In a possible mode of realization, in the handheld structure provided by the present application, the buckle assembly further comprises a second reset member, the two first buckles being connected with each other through the second reset member; the second reset member is configured to be compressed and deformed when the two first buckles approach each other; and to drive the two first buckles to move away from each other when the external force on the buckle bracket is released and the buckle bracket moves toward the second direction relative to the main unit bottom cover, so that both first buckles engage with the main unit bottom cover by snap fit.

[0024] In this way, by arranging the second reset member between the two first buckles, the first buckles are driven to reset by the second reset member, so that the first buckles can disengage more smoothly in the next disengagement operation, thereby improving user experience of the handheld structure.

[0025] In a possible mode of realization, in the handheld structure provided by the present application, the main unit connector is provided with two opposite first mounting slots, and the main unit bottom cover is provided with two opposite snap-fit slots, and the first buckles have a buckling portion, the buckling portions respectively engaging or disengaging by snap-fit with / from the snap-fit slots correspondingly through the first mounting slots; the main unit connector is provided with a second mounting slot, the buckle bracket being arranged on the second mounting slot.

[0026] In this way, it is convenient to use the first mounting slots to accommodate the first buckles respectively, and use the second mounting slot to accommodate the buckle bracket to achieve their mounting. In addition, thanks to the snap-fit connection between the buckling portions on the first buckles and the snap-fit slots of the main unit bottom cover, the structure is relatively simple and compact, and easy to process, and also helps ensure stable connection between the main unit connector and the main unit assembly.

[0027] In a possible mode of realization, the handheld structure provided by the present application has two guide strips symmetrically arranged on the buckle bracket, and the two first buckles are provided with snap slots respectively correspondingly snap fitted onto the guide strips, a surface of the snap slots facing the guide strips being a matching inclined surface;

[0028] the guide strips are configured to slide correspondingly relative to the first buckles to drive the two first buckles to move away from or approach each other.

[0029] In this way, a matching inclined surface can be arranged between the guide strips and the snap slots, so that when the guide strips move in the first direction or the second direction driven by the buckle bracket, the first buckles can move closer to or father from each other perpendicular to the first direction through the interaction between the inclined surfaces. The operation is simple, and unlocking efficiency is high.

[0030] In a possible mode of realization, the handheld structure provided by the present application is provided with a flap on the buckle bracket, the flap being located on a side of the buckle bracket facing away from the second buckle, and being partially located outside the second accommodation cavity.

[0031] In this way, it is convenient for a user to apply an external force to the flap to drive the flap to move along the first direction, thereby causing the flap to drive the buckle bracket to move, which simplifies the unlocking operation of the buckle assembly.

[0032] In a possible mode of realization, in the handheld structure provided by the present application, the dust cup connector is provided with a dust cup mounting slot, an end of the dust cup assembly facing away from the main unit assembly engaging or disengaging by snap-fit with / from the dust cup mounting slot through the locking assembly.

[0033] In this way, it is convenient to use cooperation between the dust cup mounting slot and the locking assembly to realize mounting of the dust cup assembly.

[0034] In a possible mode of realization, in the handheld structure provided by the present application, the locking assembly comprises a locking member and a lock slot, one of the locking member and the lock slot is located on the dust cup connector, and the other is located at an end of the dust cup assembly facing away from the main unit assembly, the locking member being connected or disconnected with the lock slot.

[0035] In this way, by respectively providing the locking member and the lock slot on the dust cup assembly and the dust cup connector, use of snap-fit cooperation between the locking member and the lock slot is facilitated, the structure is simple, and snap-fit between the dust cup assembly and the dust cup connector is realized. Moreover, by arranging the locking assembly at the end of the dust cup assembly facing away from the main unit assembly, interference between the locking assembly and the buckle assembly can be prevented, and the locking assembly and the main unit assembly respectively fix the dust cup assembly from two ends of the dust cup assembly, so as to ensure that the locking assembly is easy to operate, and the dust cup assembly has high mounting stability.

[0036] In a possible mode of realization, in the handheld structure provided by the present application, the dust cup mounting slot forms the lock slot, and a locking slot is arranged at an end of the dust cup assembly facing away from the main unit assembly, the locking member being arranged in the locking slot and moving relative to the locking slot so as to insert or exit the locking slot.

[0037] In this way, the dust cup mounting slot can serve as a lock slot, saving the number of holes and slots on the dust cup connector, simplifying the structure of the dust cup connector, and making it easier to process. With the locking member arranged in the locking slot, the dust cup assembly is unlocked by moving relative to the locking slot, which also facilitates further simplifying the unlocking operation of the locking assembly.

[0038] In a possible mode of realization, in the handheld structure provided by the present application, the locking assembly further comprises a locking bracket and a third reset member, the locking bracket being arranged in the locking slot, the locking member being connected to the locking bracket through the third reset member; the locking member is configured to drive the third reset member to be compressed and deformed when the locking member is pressed by an external force, so as to move toward the locking bracket, thereby inserting into the locking slot; the third reset member is configured to restore the deformation when the external force on the locking member is released, so as to drive the locking member to partially exit the locking slot.

[0039] In this way, after the locking member is pressed into the locking slot by an external force to unlock the dust cup assembly, it can reset itself driven by the third reset member when the external force is removed, which simplifies the operation of the locking assembly and improving user experience.

[0040] In a possible mode of realization, in the handheld structure provided by the present application, the mounting base body comprises a mounting base front shell and a mounting base rear shell connected to the mounting base front shell, the mounting base rear shell being connected to a face of the main unit connector facing away from the main unit assembly.

[0041] In this way, by providing that the mounting base rear shell and the mounting base front shell are detachably connected, flexibly adding other parts or providing other hole or slot structures between the mounting base rear shell and the mounting base front shell is facilitated, so as to make the overall structure of the mounting base more comprehensive.

[0042] In a possible mode of realization, in the handheld structure provided by the present application, the mounting base front shell is provided with a receiving slot, the air duct being located in the receiving slot, the dust cup connector being arranged on the mounting base front shell, the dust cup connector and the main unit connector jointly covering the receiving slot.

[0043] In this way, with the dust cup connector and the main unit connector jointly covering the receiving slot, the air duct can be more stably arranged in the receiving slot, and fixing components of the air duct can be omitted, so that the structure of the mounting base is simple and compact.

[0044] In a possible mode of realization, in the handheld structure provided by the present application, the dust cup connector is provided with a first communicating hole, the air duct and the air inlet being in communication through the first communicating hole.

[0045] In this way, the air duct and the dust cup assembly can be connected through the first communicating hole, so that a smooth airflow channel is formed between the dust cup assembly and the air duct, ensuring that the handheld structure can operate stably.

[0046] In a possible mode of realization, in the handheld structure provided by the present application, at least one of the mounting base rear shell and the mounting base front shell is provided with a second air outlet; the main unit connector has a second communicating hole, the first air outlet being in communication with the second air outlet located on the mounting base front shell through the second communicating hole.

[0047] In this way, the position of the second air outlet can be flexibly set according to needs, so that the handheld structure has two air outlet directions, which improves user experience.

[0048] In a possible mode of realization, in the handheld structure provided by the present application, the main unit assembly further comprises a main unit front cover connected to the main unit body, the main unit front cover engaging with an end of the dust cup assembly by snap fit; the dust cup assembly is in communication with the main unit body through the main unit front cover.

[0049] In this way, the main unit assembly and the dust cup assembly are snap fitted and communicate through the main unit front cover, so as to form a smooth airflow channel between the main unit assembly and the dust cup assembly, so that suction by the handheld structure operates more smoothly.

[0053] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar components or components with the same or similar functions. The described embodiments are some, not all, of the embodiments of the present application. The embodiments described below with reference to the drawings are exemplary, are intended to be used to explain the present application, and cannot be understood as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0054] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "mount", "connect" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, or indirect connection through an intermediate medium, or internal communication between two elements or an interaction relationship between two elements. For those skilled in the art, specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0055] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate orientation or position relationships based on the drawings, which are only for the convenience of describing the present application and simplifying the description, do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

[0056] The terms "first", "second", "third" (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented, for example, in an order other than those illustrated or described herein.

[0057] In addition, the terms "comprise / include" and "have" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or display comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or displays.

[0058] In the relevant art, a cleaning appliance has a handheld structure comprising a dust cup assembly and a main unit assembly. The main unit assembly is detachably connected to a main body of the appliance. The main unit assembly and the dust cup assembly are usually connected by a snap / buckle locking structure. The main unit assembly is used to provide a suction force, while the dust cup assembly is used to collect sucked dust and debris.

[0059] When the main unit assembly is connected only to the dust cup assembly, it can also be used alone. In this situation, an accessory such as a vacuum tube or a floor brush is also connected to a port of the dust cup assembly facing away from the main unit assembly.

[0060] However, after the dust cup assembly is assembled with the accessory, the accessory is in direct contact with a surface to be cleaned, the contact force is further transmitted to the snap locking structure. But the connection strength of the snap locking structure is weak, and it is easy to break and fail after long-term stress. As a result, the reliability of the connection between the main unit assembly and the dust cup assembly, that relies only on the snap locking structure, is poor, and the service life is short.

[0061] In view of the above problem, the present application provides a handheld structure, which provides a mounting base so that when a main unit assembly and a dust cup assembly are connected and used separately alone, the mounting base is connected to the main unit assembly and the dust cup assembly respectively, thereby dispersing the force at the connection between the main unit assembly and the dust cup assembly and thus improving the reliability of the connection between the main unit assembly and the dust cup assembly.

[0062] Specific modes of realization of the handheld structure provided by embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0063] In reference to Figs. 1 to 3, the handheld structure provided by an embodiment of the present application comprises a mounting base 100, a main unit assembly 200 and a dust cup assembly 300 detachably connected to the main unit assembly 200. The mounting base 100 comprises a mounting base body, a main unit connector 110 and a dust cup connector 120. The main unit connector 110 and the dust cup connector 120 are both connected to the mounting base body. The main unit assembly 200 is detachably connected to the main unit connector 110. The dust cup assembly 300 is detachably connected to the dust cup connector 120.

[0064] It can be understood that an adaptive snap-fit structure is provided between the dust cup assembly 300 and the main unit assembly 200, so that the dust cup assembly 300 and the main unit assembly 200 can be detachably connected, and the same sides of the dust cup assembly 300 and the main unit assembly 200 when they are connected with each other can be respectively further connected with the mounting base 100, thus forming three interconnection points, which are "dust cup assembly 300-main unit assembly 200", "dust cup assembly 300-mounting base 100" and "main unit assembly 200-mounting base 100". Furthermore, when the main unit assembly 200 and the dust cup assembly 300 are used separately alone, the force of the original connection between the dust cup assembly 300 and the main unit assembly 200 can be further dispersed to between the dust cup assembly 300 and the mounting base 100, and between the main unit assembly 200 and the mounting base 100 through the mounting base 100, so that the force on the snap-fit (buckle) structure between the dust cup assembly 300 and the main unit assembly 200 is reduced. In other words, the connection between the dust cup assembly 300 and the main unit assembly 200 is reinforced by the mounting base 100, so that the connection reliability between the dust cup assembly 300 and the main unit assembly 200 is improved.

[0065] On the same side of the mounting base 100, a main unit connector 110 correspondingly detachably connected to the main unit assembly 200 and a dust cup connector 120 correspondingly detachably connected to the dust cup assembly 300 are fixedly arranged. Thus, during specific connection, the main unit assembly 200 can be connected to the dust cup assembly 300 first, and then the connected two parties can be connected correspondingly to the main unit connector 110 and the dust cup connector 120, so that both the main unit assembly 200 and the dust cup assembly 300 are connected to the mounting base 100. Alternatively, the main unit assembly 200 can be connected to the main unit connector 110 first, and then the dust cup assembly 300 can be connected to the dust cup connector 120, and at the same time when the dust cup assembly 300 is connected to the dust cup connector 120, the dust cup assembly 300 may be naturally connected to the main unit assembly 200, and finally the main unit assembly 200 and the dust cup assembly 300 may be both connected to the mounting base 100. That is, the present application does not limit the mounting sequence between the main unit assembly 200, the dust cup assembly 300 and the mounting base 100, and there is no need to limit it. The mounting base 100 can be used to improve the reliability of connection between the main unit assembly 200 and the dust cup assembly 300.

[0066] Thus, the handheld structure provided by the embodiment of the present application, by providing the mounting base 100 having a main unit connector 110 and a dust cup connector 120, realizes the connection between the main unit assembly 200 and the mounting base 100 by means of the main unit connector 110, and realizes the connection between the dust cup assembly 300 and the mounting base 100 by means of the dust cup connector 120.

[0067] On the basis of the detachable connection between the main unit assembly 200 and the dust cup assembly 300, the reliability of connection between the main unit assembly 200 and the dust cup assembly 300 is enhanced by connecting the mounting base 100 to the main unit assembly 200 and the dust cup assembly 300 respectively. In this way, the force at the connection between the main unit assembly 200 and the dust cup assembly 300 can be dispersed to the mounting base 100, reducing the direct force on the main unit assembly 200 and the dust cup assembly 300, thereby improving the reliability of connection between the main unit assembly 200 and the dust cup assembly 300, and extending the service life of the connection between the main unit assembly 200 and the dust cup assembly 300.

[0068] And it should be noted that, in Figs. 1 to 14, the X direction, Y direction and Z direction shown are set such that any two of them are perpendicular to each other in three-dimensional space. The mounting base 100 is arranged along the Y direction in general. The dust cup assembly 300 and the main unit assembly 200 are arranged along the Z direction relative to the mounting base 100. The dust cup assembly 300 and the main unit assembly 200 are arranged along the Y direction relative to each other. Both the dust cup assembly 300 and the main unit assembly 200 extend along the Y direction.

[0069] In some embodiments, in reference to Figs. 1 to 3, the handheld structure further comprises a buckle assembly 400. The main unit assembly 200 and the main unit connector 110 are connected or disconnected through the buckle assembly 400.

[0070] It is easy to understand that by providing the buckle assembly 400 between the main unit assembly 200 and the main unit connector 110, the detachable connection between the main unit assembly 200 and the main unit connector 110 is realized, thereby avoiding direct snap-fit or insertion connection between the main unit assembly 200 and the main unit connector 110, and which can make assembly and disassembly between the main unit assembly 200 and the main unit connector 110 more convenient and quicker.

[0071] In addition, compared with a direct snap-fit or insertion connection between the main unit assembly 200 and the main unit connector 110, the buckle assembly 400 has a higher connection reliability, which also helps ensure that the connection between the main unit assembly 200 and the dust cup assembly 300 is stable and reliable and has a longer service life.

[0072] In some other embodiments, as shown in Figs. 1, 2, 3 and 9, the handheld structure further comprises a locking assembly 500, and the end of the dust cup assembly 300 facing away from the main unit assembly 200 is engaged or disengage by snap-fit with the dust cup connector 120 through the locking assembly 500.

[0073] In this way, by providing the locking assembly 500 between the dust cup assembly 300 and the dust cup connector 120, the end of the dust cup assembly 300 facing away from the main unit assembly 200 is connected to the dust cup connector 120, while the end of the dust cup assembly 300 close to the main unit assembly 200 is connected to the main unit assembly 200, so that the two ends of the dust cup assembly 300 are fixed, ensuring the reliability of connection between the dust cup assembly 300, the main unit assembly 200 and the mounting base 100, and making the overall structure of the handheld structure simpler and more compact.

[0074] In addition, in some embodiments, in reference to Figs. 1 to 4, the mounting base 100 has an air duct 130, and the dust cup assembly 300 has an air inlet 311. The air duct 130 is in communication with the air inlet 311. The dust cup assembly 300 is in communication with the main unit assembly 200. The main unit assembly 200 has a first air outlet 211, and the mounting base 100 has at least one second air outlet 141. The first air outlet 211 is in communication with the second air outlet 141.

[0075] It can be understood that by providing the air duct 130 connected to the air inlet 311 of the dust cup assembly 300 and the second air outlet 141 connected to the first air outlet 211 of the main unit assembly 200 on the mounting base 100, the air duct 130 extends along the Y direction in Fig. 2, which is consistent with the extension direction of the main unit assembly 200 and the dust cup assembly 300. Therefore, the air flow channel between the dust cup assembly 300 and the main unit assembly 200 can extend through the mounting base 100 to form a complete air flow channel with both inlet and outlet arranged on the mounting base 100.

[0076] Thus, when the main unit assembly 200 and the dust cup assembly 300 are used independently alone relative to the handheld structure main body, accessories such as a vacuum tube or floor brush can be connected to the mounting base 100 through the air duct 130 instead of being connected to the dust cup assembly 300, so as to avoid direct contact and force between the dust cup assembly 300 and the surface to be cleaned through the accessory, which improves the stability of connection between each of the main unit assembly 200 and the dust cup assembly 300, and the mounting base 100, thereby ensuring the stability and reliability of connection between the main unit assembly 200 and the dust cup assembly 300.

[0077] Moreover, compared with directly arranging the air duct 130 on the dust cup assembly 300 and directly connecting the accessory to the dust cup assembly 300 through the air duct 130, arranging the air duct 130 on the mounting base 100 can also place the air duct 130 farther from the main unit assembly 200 and increase the distance between the main unit assembly 200 and the air inlet end of the air flow channel, so as to reduce operating noise of driving parts in the main unit assembly 200 when the main unit assembly 200 and the dust cup assembly 300 are connected and used independently alone, thereby improving utilization experience.

[0078] Further, in some embodiments, in reference to in Figs. 1 to 8, the main unit assembly 200 comprises a main unit body 210 and a main unit bottom cover 220. The main unit bottom cover 220 is arranged on the main unit body 210, and encloses a first accommodation cavity with the main unit body 210. The main unit connector 110 is arranged on the mounting base body, and encloses a second accommodation cavity with the mounting base body. The buckle assembly 400 is at least partially located in one of the first accommodation cavity and the second accommodation cavity, so as to engage or disengage by / from snap-fit with the main unit connector 110 or the main unit bottom cover 220 of the other accommodation cavity.

[0079] It can be understood that the main unit body 210 and the main unit bottom cover 220 form by enclosure the first accommodation cavity of the main unit assembly 200, and the main unit connector 110 and the mounting base 100 form by enclosure the second accommodation cavity. Therefore, the first accommodation cavity and the second accommodation cavity can be configured to be matched in cooperation with each other in their outer side wall structures opposite to each other in the Z direction in Fig. 3. That is, the main unit bottom cover 220 and the main unit connector 110 are adapted in cooperation on opposite sides, so that when the main unit assembly 200 is connected to the mounting base 100, the main unit bottom cover 220 and the main unit connector 110 abut more closely with each other to ensure more reliable connection.

[0080] The buckle assembly 400 is arranged in the first accommodation cavity at the side of the main unit assembly 200, or in the second accommodation cavity at the side of the mounting base 100, and the buckle assembly 400 partially protrudes from the accommodation cavity where it is located, so as to engage or disengage by / from snap-fit with the other one to ensure stable connection between the main unit assembly 200 and the mounting base 100.

[0081] Furthermore, since the embodiment of the present application does not limit the position where the buckle assembly 400 is arranged, the buckle assembly 400 can be flexibly arranged where it is more convenient for mounting and operation, or where less space is occupied and it is more concealed, according to specific use requirements and related structural arrangement, so as to make the structure of the handheld structure more compact and make assembly and disassembly between the main unit assembly 200 and the mounting base 100 more convenient and quicker.

[0082] Since the main unit connector 110 is arranged on the rear side of the mounting base body along the Y direction in Figure 3, the main unit assembly 200 is located at the rear of the mounting base 100 along the Y direction. Thus, the dust cup connector 120 and the corresponding dust cup assembly 300 can be arranged on the front side of the mounting base 100 along the Y direction, so that the dust cup assembly 300 and the main unit assembly 200 are arranged front and rear along the Y direction of the mounting base 100. In another embodiment, according to the specific mode of connection of the main unit assembly 200 and the dust cup assembly 300, for example, the main unit assembly 200 and the dust cup assembly 300 can be arranged in parallel along the X direction, and the structure of the mounting base 100 is correspondingly arranged. Then, according to the structure of the mounting base 100, suitable components are selected as the main unit connector 110 and the dust cup connector 120. This is not limited by the present application.

[0083] Besides, in a possible embodiment, in reference to Fig. 1, 3, 4, and 10 to 14, the buckle assembly 400 comprises a buckle bracket 410 and two first buckles 420. The two first buckles 420 are both connected to the buckle bracket 410. The buckle bracket 410 is configured to be partially located outside the second accommodation cavity, and when pushed or pulled by an external force, moves in a first direction (for example, as shown by the direction indicated by the arrow in the Y direction in Figs. 13 and 14) relative to the main unit bottom cover 220 and drives the two first buckles 420 to approach (close to) each other, so that the first buckles 420 both disengage from snap-fit from the main unit cover 220. That is, it controls the two first buckles 420 to move in opposite directions along the X direction respectively.

[0084] It should be noted that the first direction can be consistent with the direction indicated by the arrow in the Y direction, or it can be opposite to the direction indicated by the arrow in the Y direction. This is not limited by the present application. For example, it can be provided that the buckle bracket 410 moves along the side indicated by the arrow in the Y direction (the first direction) and thus drives the two first buckles 420 to approach each other along the X direction.

[0085] By providing the buckle bracket 410 and the first buckles 420 connected to the buckle bracket 410 to form the buckle assembly 400, the number of its own parts is relatively few, which makes it easy to make the structure of the buckle assembly 400 compact and convenient to arrange it in the first accommodation cavity or the second accommodation cavity, which have limited space.

[0086] Both the first buckles 420 are connected to the buckle bracket 410. Thus, the two first buckles 420 can be moved at the same time by one push-pull action of the buckle bracket 410, so that the buckle assembly 400 is easy to operate, and the efficiency of assembly and disassembly between the main unit assembly 200 and the main unit connector 110 is improved. In addition, the main unit assembly 200 and the main unit connector 110 are locked from two opposite directions in the X direction by the two first buckles 420, forming a double locking, which also results in high reliability of connection between the main unit connector 110 and the main unit assembly 200.

[0087] Further, still in reference to Figures 1, 3, 4, and 10 to 12, in some embodiments, the buckle bracket 410 has a second buckle 411, and the main unit bottom cover 220 has a buckling slot 221 matching with the second buckle 411. The second buckle 411 is configured to move with the buckle bracket 410 and disengage / disconnect from the buckling slot 221 synchronously and perpendicularly to the first buckles 420.

[0088] Specifically, the second buckle 411 can be arranged along the Y direction in Fig. 10 at an end of the buckle bracket 410 facing away from the first buckles 420, so that when the buckle bracket 410 moves along the Y direction, the second buckle 411 can be driven to move synchronously along the Y direction, and the two first buckles 420 can be driven by the buckle bracket 410 to move along the X direction. It can be seen that the movement direction of the first buckles 420 is perpendicular to the movement direction of the second buckle 411.

[0089] Thus, by arranging the second buckle 411 on the buckle bracket 410, the second buckle 411 can be used to form a third locking effect along a locking direction different from that of the first buckles 420, in addition to the double locking provided by the first buckles 420, which further strengthens the snap-fit connection between the buckle assembly 400 and the main unit assembly 200, and further strengthens the reliability of connection between the main unit assembly 200 and the mounting base 100.

[0090] In specific implementation, the second buckle 411 can be arranged to be fixedly connected or integrally formed in one piece with the end of the buckle bracket 410 facing away from the first buckles 420.

[0091] Furthermore, in some modes of realization of this embodiment, as shown in Fig. 1, 4, 13 and 14, the buckle assembly 400 further comprises a first reset member 430. A first mounting portion 111 is provided on the main unit connector 110. A second mounting portion 412 is provided on the buckle bracket 410. Two ends of the first reset member 430 are respectively sleeved on the first mounting portion 111 and the second mounting portion 412. The first reset member 430 is configured to be compressed and deformed so that the second buckle 411 is unlocked from the buckling slot 221 when the buckle bracket 410 moves toward the first direction under the action of an external force, and to drive the buckle bracket 410 to move toward the second direction (for example, the opposite direction of the direction indicated by the arrow in the Y direction in Fig. 13 and 14) so as to drive the second buckle 411 to engage with the buckling slot 221 by snap fit when the external force on the buckle bracket 410 is released, wherein the first direction is opposite to the second direction.

[0092] It can be understood that after the buckle bracket 410 drives the first buckles 420 to unlock the main unit assembly 200 from the main unit connector 110, it is necessary to also return the first buckles 420 to their initial position before unlocking so that the next unlocking operation can be carried out smoothly.

[0093] Therefore, by providing the first reset member 430, the buckle bracket 410 is slidably connected with the main unit connector 110 through the first reset member 430. Since the first reset member 430 can be compressed and rebound, when the second buckle 411 needs to be locked and unlocked with a corresponding mounting portion, a user only needs to apply an external force to the buckle bracket 410 once, which saves time and effort and makes it convenient to operate.

[0094] In specific implementation, the first reset member 430 can be a coil spring. The first mounting portion 111 and the second mounting portion 412 are distributed along the Y direction, so that the first reset member 430 is arranged along the Y direction in Fig. 13 or 14, and is connected to the main unit connector 110 through the first mounting portion 111, and connected to the buckle bracket 410 through the second mounting portion 412. Therefore, when the buckle bracket 410 moves relative to the main unit connector 110 along the Y direction in Fig. 13 or 14, the first reset member 430 will be pushed at the same time, so that the first reset member 430 will be compressed and deformed along the Y direction in Fig. 13 or 14, and when the external force on the buckle bracket 410 is released, the first reset member 430 can be stretched and extended along the Y direction to restore the deformation and drive the second buckle 411 to be reset in the opposite direction of the arrow in the Y direction in Fig. 13 or 14, so as to drive the second buckle 411 to engage with the buckling slot 221 by snap fit when the second buckle 411 cooperates with the buckling slot 221.

[0095] In addition, in some other embodiments, still in reference to Figs. 1, 4, 12, 13 and 14, the buckle assembly 400 further comprises a second reset member 440. The two first buckles 420 are connected through the second reset member 440. The second reset member 440 is configured to be compressed and deformed when the two first buckles 420 approach each other. When an external force on the buckle bracket 410 is released and the buckle bracket 410 moves toward the second direction relative to the main unit bottom cover 220, the two first buckles 420 are driven away from each other, so that the two first buckles 420 both engage with the main unit bottom cover 220 by snap fit.

[0096] By arranging a mounting pin 423 on the first buckles 420 along the X direction in Fig. 12, and arranging the second reset member 440 extending along the X direction between the two mounting pins 423, when an external force driving the buckle bracket 410 is released and the buckle bracket 410 resets along the Y direction, the second reset member 440 can drive the two first buckles 420 to move away from each other along the X direction and return to their initial positions before unlocking. In addition, at this time, if the main unit bottom cover 220 engages with a first connecting member, the first buckles 420 can further engage with the main unit bottom cover 220 by snap fit, so that the first buckles 420 can more smoothly perform the next disconnection operation, thereby improving the user experience of the handheld structure.

[0097] Similarly, in specific implementation, the second reset member 440 can also be provided as a coil spring. With a coil spring structure, the first reset member 430 and the second reset member 440 have relatively good elastic properties and more efficiently drive the buckle bracket 410 and the first buckles 420 to reset.

[0098] Specifically, in reference to Figures 4 to 8, 10 and 12, two opposite first mounting slots 112 are provided on the main unit connector 110, and two opposite snap-fit slots 222 are provided on the main unit bottom cover 220. The first buckles 420 has a buckling portion 421. The buckling portions 421 respectively engage or disengage by / from snap-fit with the snap-fit slots 222 through the first mounting slots 112. The main unit connector 110 is provided with a second mounting slot 113. The buckle bracket 410 is arranged on the second mounting slot 113.

[0099] The two first mounting slots 112 are symmetrically distributed on two sides of the main unit connector 110 along the X direction in Figure 6 to respectively accommodate the first buckles 420. The two first buckles 420 are respectively provided with the buckling portions 421 on the opposite ends to each other. A slot opening adapted to the buckling portions 421 is also provided at the side opposites of the first mounting slots 112, so that when the main unit connector 110 and the main unit bottom cover 220 are engaged with each other, the buckling portions 421 can extend out of the first mounting slots 112 through the slot openings along the X direction, and further extend into the two opposite snap-fit slots 222 on the main unit bottom cover 220, so as to realize snap-fit between the first buckles 420 and the main unit bottom cover 220.

[0100] The main unit connector 110 is also provided with a second mounting slot 113 for accommodating / receiving the buckle bracket 410. The second mounting slot 113 extends along the Y direction and is in communication with the first mounting slots 112 on its two sides, so as to facilitate arranging the first buckles 420 respectively on two sides of the buckle bracket 410.

[0101] Thus, the first buckles 420 can be respectively accommodated by the first mounting slots 112, and the buckle bracket 410 can be accommodated by the second mounting slot 113, so as to realize the installation of the buckle assembly 400. In addition, the buckling portions 421 on the first buckles 420 snap fit and cooperate with the snap-fit slots 222 of the main unit bottom cover 220. The structure is relatively simple and compact, easy to process, and also helps ensure a stable connection between the main unit connector 110 and the main unit assembly 200.

[0102] In order to improve the efficiency and stability of snap-fit, the main unit connector 110 is further provided with a first positioning block 115 and a second positioning block 116 facing the main unit bottom cover 220, and the main unit bottom cover 220 is provided with a first positioning slot 223 and a second positioning slot 224 respectively adapted to the first positioning block 115 and the second positioning block 116. By providing a structure with positioning blocks and positioning slots that cooperate with each other, on the one hand, when the main unit assembly 200 is placed on the mounting base 100, it can be positioned more quickly and accurately, thereby improving the efficiency of snap-fit between the buckle assembly 400 and the main unit bottom cover 220; on the other hand, after the main unit assembly 200 is connected to the mounting base 100, it can also prevent the main unit assembly 200 from moving or swinging on the mounting base 100, thereby improving the stability of snap-fit between the buckle assembly 400 and the main unit bottom cover 220. Further, the first positioning block 115 may be configured as a hollow block protruding toward the first positioning slot 223, and the first mounting slot 112 may be correspondingly arranged in the hollow interior of the first positioning block 115 facing away from the first positioning slot 223, so as to make the overall structure more compact.

[0103] Furthermore, in reference to Figs. 10 to 14, two guide strips 413 are symmetrically provided on the buckle bracket 410. The two first buckles 420 are both provided with a snap slot 422. The snap slots 422 are respectively correspondingly arranged on and abut against the guide strips 413, and the surfaces of the snap slots 422 and the guide strips 413 facing to each other are matching inclined surfaces. The guide strips 413 are configured to slide correspondingly relative to the first buckles 420 to drive the two first buckles 420 to move away from or approach each other.

[0104] Specifically, by providing the surfaces where the snap slots 422 come into contact with the guide strips 413 as matching first inclined surfaces 4221 and second inclined surfaces 4131, when the buckle bracket 410 moves, the feature of the inclined surfaces will form a certain pushing force (thrust) on the first buckles 420, and play a role of guiding the movement direction of the first buckles 420 after being subjected to the force.

[0105] As an example, the guide strips 413 partially extend along the Y direction in Fig. 11, and partially tilt toward the X direction, so as to extend along a direction between the X direction and the Y direction to form the second inclined surfaces 4131. The first inclined surfaces 4221 adapted to the second inclined surface 4131 are arranged on the snap slots 422. When the buckle bracket 410 moves along the Y direction, the guide strips 413 move synchronously with the buckle bracket 410 along the Y direction, and because the second inclined surfaces 4131 on the guide strips 413 interact with the first inclined surfaces 4221 on the snap slots 422, the snap slots 422 will move relative to the guide strips 413 along the X direction.

[0106] With such arrangement, the structure of the first buckles 420 and the buckle bracket 410 can be made simpler, which makes them easy to manufacture, and after the two are connected, help make the locking structure small and compact as a whole, which will not occupy too much space and facilitate use by a user.

[0107] And in some embodiments, in reference to Figs. 1, 4, 5, 6, 10, 11 and 13, a flap 414 is provided on the buckle bracket 410. The flap 414 is located on a side of the buckle bracket 410 facing away from the second buckle. A part of the flap 414 is located outside the second accommodation cavity.

[0108] The flap 414 is arranged at a side of the buckle bracket 410 facing away from the second buckle along the Z direction in Fig. 11. Thus, when the buckle bracket 410 is arranged in the second mounting slot 113, the flap 414 can extend out of the second mounting slot 113 and be further located outside the second accommodation cavity.

[0109] Partially disposing the flap 414 outside the second accommodation cavity makes it convenient for a user to apply an external force to the flap 414 from the side of the mounting base 100 that is facing away from (opposite to) the main unit assembly 200 to drive the flap 414 to move along the Y direction, thereby causing the flap 414 to drive the buckle bracket 410 to move, which simplifies the unlocking operation of the buckle assembly 400.

[0110] In some embodiments, as shown in Figs. 1, 2, 3, 4 and 9, a dust cup mounting slot 121 is arranged on the dust cup connector 120, and an end of the dust cup assembly 300 facing away from the main unit assembly 200 engages or disengages by / from snap-fit with the dust cup mounting slot 121 through the locking assembly 500.

[0111] Thus, realizing the installation of the dust cup assembly 300 by means of cooperation between the dust cup mounting slot 121 and the locking assembly 500 is facilitated. The overall arrangement is linear along the Y direction in Figure 4. The structure is simple, and the connection is stable and reliable.

[0112] The dust cup connector 120 has an arc-shaped matching surface extending along the Y direction. By means of the arc-shaped matching surface, the connection between the dust cup assembly 300 and the dust cup connector 120 can be made more stable and fitting.

[0113] And in some embodiments, still in reference to Figs. 1, 2, 3, 4 and 9, the locking assembly 500 comprises a locking member 510 and a lock slot, one of which is located on the dust cup connector 120, and the other is located at an end of the dust cup assembly 300 facing away from the main unit assembly 200. The locking member 510 is connected or disconnected from the lock slot.

[0114] By means of the locking member 510 and the lock slot arranged respectively on the dust cup assembly 300 and the dust cup connector 120, engagement between the dust cup assembly 300 and the dust cup connector 120 by means of snap-fit cooperation between the locking member 510 and the lock slot is facilitated. The structure is simple.

[0115] In addition, by arranging the locking assembly 500 at an end of the dust cup assembly 300 facing away from the main unit assembly 200, interference between the locking assembly 500 and the buckle assembly 400 can be prevented. The locking assembly 500 and the main assembly 200 respectively fix the dust cup assembly 300 from both ends of the dust cup assembly 300 to ensure that the locking assembly 500 is easy to operate and the dust cup assembly 300 is installed with high stability.

[0116] Moreover, in some embodiments, still in reference to Figs. 1, 2, 3, 4 and 9, the dust cup mounting slot 121 forms a lock slot. A locking slot 312 is provided at one end of the dust cup assembly 300 away from the main unit assembly 200. The locking member 510 is arranged in the locking slot 312 and moves relative to the locking slot 312 to insert into or exit the locking slot 312.

[0117] The locking member 510 is engaged in a snap-fit manner with the lock slot along the Y direction in Fig. 3. Thus, when the locking assembly 500 needs to be unlocked, an external force can be applied to the locking member 510 to move the locking member 510 relative to the locking slot 312 along the Y direction, and exit the lock slot while at least partially inserting into the locking slot 312, so as to disengage from snap-fit with the lock slot.

[0118] Thus, the dust cup mounting slot 121 can serve as a lock slot, saving the number of holes and slots on the dust cup connector 120, simplifying the structure of the dust cup connector 120, and making it easier to process. The locking member 510 is arranged in the locking slot 312, and unlocks the dust cup assembly 300 by moving relative to the locking slot 312, which also helps further simplify the unlocking operation of the locking assembly 500.

[0119] Further, in reference to Figs. 3 and 4, the locking assembly 500 further comprises a locking bracket 530 and a third reset member 520. The locking bracket 530 is arranged in the locking slot 312. The locking member 510 is connected to the locking bracket 530 through the third reset member 520. The locking member 510 is configured to drive the third reset member 520 to be compressed and deformed when pressed by an external force, so as to move toward the locking bracket 530 and thus insert into the locking slot 312. The third reset member 520 is configured to restore the deformation when the external force on the locking member 510 is released, so as to drive the locking member 510 to partially exit the locking slot 312.

[0120] The locking assembly 500 is entirely arranged in the locking slot 312 through the locking bracket 530. The third reset member 520 can be a coil spring identical to the first reset member 430 and the second reset member 440. The third reset member 520 is arranged along the Y direction, of which one end abuts against the locking member 510 and another end abuts against the locking bracket 530. Thus, the third reset member 520 can realize a movable connection between the locking member 510 and the locking bracket 530.

[0121] When the locking member 510 is pressed into the locking slot 312 by an external force to unlock the dust cup assembly 300, the third reset member 520 is pressed by the external force and thus compressed and deformed. When the external force is removed, the third reset member 520 automatically extends to drive the locking bracket to reset along the Y direction, and at least partially extends out of the locking slot 312. When the dust cup assembly 300 and the dust cup connector 120 engage with each other, the locking member 510 engages with the dust cup mounting slot 121 by snap fit. The operation of the locking assembly 500 is simplified, and user experience is improved.

[0122] And because an end of the dust cup connector 120 facing away from the main unit connector 110 is provided with an inclined protrusion, the dust cup mounting slot 121 can be arranged at the inclined protrusion, and a bypass slot adapted to the inclined protrusion is provided on the dust cup assembly 300, so that the connection between the dust cup assembly 300 and the mounting base 100 is tighter and more reliable.

[0123] In addition, in some embodiments, as shown in Figs. 2 to 4, the mounting base body comprises a mounting base front shell 140 and a mounting base rear shell 150 connected to the mounting base front shell 140. The mounting base rear shell is connected to a face of the main unit connector 110 facing away from the main unit assembly 200.

[0124] In this way, by providing that the mounting base rear shell 150 and the mounting base front shell 140 are detachably connected, it is convenient to flexibly add other parts or provide other hole or slot structures between the mounting base rear shell 150 and the mounting base front shell 140, so as to make the overall structure of the mounting base 100 more comprehensive.

[0125] A mounting base bottom shell 160 connected to the mounting base front shell 140 and the mounting base rear shell 150 can also be provided to improve the structural stability of the mounting base 100.
