Description

Technical Field

[0001] This application relates to the technical field of household cleaning appliances, and particularly to a handheld structure. Background Art

[0002] Cleaning devices (such as vacuum cleaners, floor washers, etc.) can suck up dust, dirt, etc. on the ground to keep the ground clean.

[0003] In the related art, a cleaning device has a handheld structure. The handheld structure includes a dust cup assembly and a main body assembly. The main body assembly is detachably connected to the device main body. The main body assembly and the dust cup assembly are usually connected in cooperation through a buckle structure. The main body assembly is used to provide suction force, and the dust cup assembly is used to collect the inhaled dust and dirt.

[0004] However, the connection strength of the buckle structure is relatively low and it is prone to breakage and failure after long-term stress. Therefore, the connection reliability between the main body assembly and the dust cup assembly relying only on the buckle structure is poor and the service life is short. Summary of the Invention

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

[0006] The handheld structure provided by this application includes a mounting base, a main body assembly, and a dust cup assembly. The dust cup assembly is detachably connected to the main body assembly. The mounting base includes a mounting base body, a main body connecting member, and a dust cup connecting member. Both the main body connecting member and the dust cup connecting member are connected to the mounting base body. The main body assembly is detachably connected to the main body connecting member, and the dust cup assembly is detachably connected to the dust cup connecting member.

[0007] The handheld structure provided by this application realizes the connection between the main body assembly and the mounting base by using the main body connecting member and realizes the connection between the dust cup assembly and the mounting base by using the dust cup connecting member by providing a mounting base with a main body connecting member and a dust cup connecting member. On the basis that the main body assembly and the dust cup assembly are detachably connected to each other, the main body assembly and the dust cup assembly are further connected to each other through the mounting base, thereby strengthening the connection reliability between the main body assembly and the dust cup assembly. In this way, the stress at the connection between the main body assembly and the dust cup assembly can be dispersed to the mounting base, reducing the direct stress on the main body assembly and the dust cup assembly, thereby improving the connection reliability between the main body assembly and the dust cup assembly and extending the service life of the connection between the main body assembly and the dust cup assembly.

[0008] In a possible implementation manner, the handheld structure provided by this application further includes a buckle assembly. The main body assembly is connected or disconnected from the main body connecting member through the buckle assembly.

[0009] In this way, by setting the latch assembly to achieve the detachable connection between the host component and the host connector, the connection and disconnection between the host component and the host connector can be made more convenient and fast, and the connection reliability between the host component and the host connector can be improved to ensure the stable and reliable connection between the host component and the dust cup component.

[0010] In a possible implementation manner, the handheld structure provided by the present application further includes a locking assembly, and one end of the dust cup component facing away from the host component is clamped or disengaged from the dust cup connector through the locking assembly.

[0011] In this way, by setting the locking assembly to achieve the connection between one end of the dust cup component facing away from the host component and the dust cup connector, it is convenient to connect one end of the dust cup component close to the host component to the host component, making the overall structure simpler and more compact, and ensuring that both ends of the dust cup component are connected and fixed, and also facilitating to ensure the connection reliability between the dust cup assembly and the host component and the mounting base.

[0012] In a possible implementation manner, for the handheld structure provided by the present application, the mounting base has an air duct, and the dust cup component has an air inlet, and the air duct is communicated with the air inlet;

[0013] The dust cup component is communicated with the host component;

[0014] The host component has a first air outlet, and the mounting base has at least one second air outlet, and the first air outlet is communicated with the second air outlet.

[0015] In this way, by setting the air duct and the second air outlet on the mounting base, and making the air duct communicate with the air inlet of the dust cup component and the second air outlet communicate with the first air outlet of the host component, a complete air flow channel can be formed among the mounting base, the dust cup component and the host component, and both the inlet and outlet ports of the air flow channel are arranged on the mounting base. Thereby, when the host component and the dust cup component are used separately relative to the main body of the handheld structure, the mounting base contacts and bears force on the cleaning surface, avoiding the direct force on the dust cup component and the host component, and further improving the connection stability of the host component and the dust cup component to the mounting base respectively, so as to ensure the stable and reliable connection between the host component and the dust cup component. And compared with the air duct being directly arranged on the dust cup component, the air duct arranged on the mounting base is farther away from the host component, which is convenient for reducing the running noise when the host component and the dust cup component are used separately and improving the use experience.

[0016] In a possible implementation manner, for the handheld structure provided by the present application, the host component includes a host body and a host bottom cover, the host bottom cover is arranged on the host body and encloses a first accommodation cavity with the host body;

[0017] The host connector is arranged on the mounting base body and encloses a second accommodation cavity with the mounting base body;

[0018] The latch assembly is at least partially located in one of the first accommodation cavity and the second accommodation cavity to be snap-connected or disengaged from the host connection member or the host bottom cover of the other one.

[0019] In this way, by forming the first accommodation cavity on the host assembly and the second accommodation cavity on the mounting base, the latch assembly can be arranged on the host assembly or the mounting base and connected to the other one, so as to ensure the stable connection between the host assembly and the mounting base, and realize the flexible arrangement of the latch assembly on a more convenient one for installation operation, thereby making the structure of the handheld structure more compact and making the connection and disassembly between the host assembly and the mounting base more convenient and fast.

[0020] In a possible implementation manner, for the handheld structure provided by the present application, the latch assembly includes a latch bracket and two first latches, and both of the two first latches are connected to the latch bracket;

[0021] The latch bracket is configured to be partially located outside the second accommodation cavity, and when being pushed or pulled by an external force, move in the first direction relative to the host bottom cover and drive the two first latches to approach each other, so that the first latches are disengaged from the snap connection with the host bottom cover.

[0022] In this way, by setting both of the two first latches to be connected to the latch bracket, it is convenient to simultaneously move the two first latches by pushing or pulling the latch bracket, so that the connection reliability between the latch assembly and the host assembly is relatively high, and the disassembly operation is more convenient and the disassembly efficiency is relatively high.

[0023] In a possible implementation manner, for the handheld structure provided by the present application, the latch bracket is provided with a second latch, and the host bottom cover is provided with a buckle groove matching the second latch;

[0024] The second latch is configured to move along with the latch bracket and be snap-connected or disengaged from the buckle groove synchronously and perpendicularly to the first latch.

[0025] In this way, by providing the second latch on the latch bracket, the second latch can be used to further strengthen the snap connection effect between the latch assembly and the host assembly on the basis of the two first latches, thereby improving the connection reliability between the host assembly and the mounting base.

[0026] In a possible implementation manner, for the handheld structure provided by the present application, the latch assembly further includes a first reset member, the host connection member is provided with a first mounting portion, the latch bracket is provided with a second mounting portion, and two ends of the first reset member are respectively sleeved on the first mounting portion and the second mounting portion;

[0027] The first reset member is configured to be compressed and deformed when the latch bracket moves in the first direction under the action of an external force, so that the second latch is disengaged from the latch groove;

[0028] When the external force on the latch bracket is released, the latch bracket is driven to move in the second direction to drive the second latch to engage with the buckle groove, where the first direction is opposite to the second direction.

[0029] In this way, by arranging the first reset member between the latch bracket and the main body connecting member and using the first reset member to drive the latch bracket to reset, the use experience of the latch assembly can be improved for unlocking operation again.

[0030] In a possible implementation manner, for the handheld structure provided in the present application, the latch assembly further includes a second reset member, and the two first latches are connected by the second reset member;

[0031] The second reset member is configured to be compressed and deformed when the two first latches approach each other;

[0032] When the external force on the latch bracket is released and the latch bracket moves in the second direction relative to the main body bottom cover, the two first latches are driven to move away from each other so that both of the two first latches engage with the main body bottom cover.

[0033] In this way, by arranging the second reset member between the two first latches and using the second reset member to drive the first latch to reset, the first latch can perform the next disengagement operation more smoothly, improving the use experience of the handheld structure.

[0034] In a possible implementation manner, for the handheld structure provided in the present application, two opposite first mounting grooves are provided on the main body connecting member, two opposite engaging grooves are provided on the main body bottom cover, and a latch portion is provided on the first latch. The latch portion is correspondingly engaged with or disengaged from the engaging groove through the first mounting groove;

[0035] A second mounting groove is provided on the main body connecting member, and the latch bracket is arranged in the second mounting groove.

[0036] In this way, it is convenient to use the first mounting groove to accommodate the first latch respectively and the second mounting groove to accommodate the latch bracket for its installation. And through the engagement between the latch portion on the first latch and the engaging groove on the main body bottom cover, the structure is relatively simple and compact, easy to process, and also convenient to ensure the stable connection between the main body connecting member and the main body assembly.

[0037] In a possible implementation manner, for the handheld structure provided in the present application, two guiding bars are symmetrically arranged on the latch bracket, card slots are provided on both of the two first latches, the card slots are respectively clamped on the guiding bars, and the surfaces of the card slots opposite to the guiding bars are matching inclined surfaces;

[0038] The guiding bars are configured to slide relative to the first latch correspondingly to drive the two first latches to move away from each other or approach each other.

[0039] In this way, a matching inclined surface can be set between the guide bar and the card slot so that when the guide bar moves along the first direction or the second direction under the drive of the lock bracket, the first lock and the second lock can be moved closer to or away from each other perpendicular to the first direction through the interaction between the inclined surfaces, which is easy to operate and has high unlocking efficiency.

[0040] In one possible implementation, the handheld structure provided in the present application has a paddle disposed on the lock bracket, the paddle is located on a side of the lock bracket facing away from the second lock, and the paddle portion is located outside the second accommodating cavity.

[0041] In this way, the user can apply external force to the paddle to drive the paddle to move along the first direction, thereby causing the paddle to drive the lock bracket to move, thereby simplifying the unlocking operation of the lock assembly.

[0042] In one possible implementation, the handheld structure provided in the present application has a dust cup mounting groove provided on the dust cup connector, and the end of the dust cup assembly facing away from the main assembly is engaged or disengaged with the dust cup mounting groove through a locking assembly.

[0043] In this way, the dust cup assembly can be easily installed by utilizing the mutual cooperation between the dust cup installation groove and the locking assembly.

[0044] In one possible implementation, the handheld structure provided by the present application, the locking assembly includes a locking member and a locking slot, one of the locking member and the locking slot is located on the dust cup connector, and the other is located at the end of the dust cup assembly facing away from the main assembly, and the locking member is connected or disconnected from the lock slot.

[0045] In this way, by respectively providing the locking member and the locking groove on the dust cup assembly and the dust cup connector, the locking member and the locking groove are conveniently engaged, resulting in a simple structure and achieving the engagement of the dust cup assembly and the dust cup connector. Furthermore, the locking member is provided at the end of the dust cup assembly facing away from the main assembly, thereby preventing interference between the locking member and the locking assembly. Furthermore, the locking member and the main assembly secure the dust cup assembly from both ends of the dust cup assembly, thereby ensuring easy operation of the locking member and high installation stability of the dust cup assembly.

[0046] In one possible implementation, the handheld structure provided by the present application has a dust cup mounting groove forming a locking groove, a locking groove is provided at one end of the dust cup assembly facing away from the main assembly, a locking member is provided in the locking groove and moves relative to the locking groove to be inserted into or out of the locking groove.

[0047] In this way, the dust cup mounting groove can be used as a locking groove, reducing the number of holes and grooves on the dust cup connector, simplifying the structure of the dust cup connector and making it easier to process. The locking member is set in the locking groove and unlocks the dust cup assembly by moving relative to the locking groove, which also facilitates the unlocking operation of the locking assembly.

[0048] In a possible implementation, for the handheld structure provided by the present application, the locking assembly further includes a locking bracket and a third reset member. The locking bracket is disposed in the locking groove, and the locking member is connected to the locking bracket through the third reset member;

[0049] The locking member is configured such that when pressed by an external force, it drives the third reset member to be compressed and deformed, so as to move toward the locking bracket and thus insert into the locking groove;

[0050] The third reset member is configured such that when the external force on the locking member is released, it restores its deformation to drive the locking member to partially withdraw from the locking groove.

[0051] In this way, when the locking member is pressed by an external force into the locking groove to unlock the dust cup assembly, it can automatically reset under the drive of the third reset member when the external force is removed, simplifying the operation of the locking assembly and enhancing the user experience.

[0052] In a possible implementation, for the handheld structure provided by the present application, the mounting base body includes a mounting base front shell and a mounting base rear shell. The mounting base rear shell is connected to the mounting base front shell, and the mounting base rear shell is connected to the side of the host connector facing away from the host assembly.

[0053] In this way, by detachably connecting the mounting base rear shell and the mounting base front shell, it is convenient to flexibly add other parts or provide other hole and groove structures between the mounting base rear shell and the mounting base front shell, making the overall structure of the mounting base more comprehensive.

[0054] In a possible implementation, for the handheld structure provided by the present application, a receiving groove is provided on the mounting base front shell, the air duct is located in the receiving groove, the dust cup connector is provided on the mounting base front shell, and the dust cup connector and the host connector jointly cover the receiving groove.

[0055] In this way, by jointly covering the receiving groove with the dust cup connector and the host connector, the air duct can be more stably located in the receiving groove, and the fixing components of the air duct can be saved, making the structure of the mounting base simple and compact.

[0056] In a possible implementation, for the handheld structure provided by the present application, a first communication hole is provided on the dust cup connector, and the air duct is communicated with the air inlet through the first communication hole.

[0057] In this way, the air duct and the dust cup assembly can be connected through the first communication hole to form an unobstructed air flow channel between the dust cup assembly and the air duct, ensuring the stable operation of the handheld structure.

[0058] In a possible implementation, for 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;

[0059] The host connector has a second communication hole, and the first air outlet is communicated with the second air outlet located on the mounting base front shell through the second communication hole.

[0060] In this way, the position of the second air outlet can be flexibly set according to requirements, so that the handheld structure has two air outlet directions, improving the user experience.

[0061] In a possible implementation manner, for the handheld structure provided in this application, the host component further includes a host front cover, which is connected to the host body and is snap-connected to the end of the dust cup component;

[0062] The dust cup component communicates with the host body through the host front cover.

[0063] In this way, the host component and the dust cup component are snap-connected and communicated through the host front cover, so as to form a smooth air flow channel between the host component and the dust cup component, making the suction operation of the handheld structure smoother.

[0087] 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 with reference to the accompanying drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals represent the same or similar components or components with the same or similar functions from beginning to end. The described embodiments are some but not all of the embodiments of the present application. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application. The embodiments of the present application will be described in detail below with reference to the drawings.

[0088] In the description of the present application, it should be noted that, unless otherwise clearly defined and limited, the terms "mounted", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, or an indirect connection through an intermediate medium, or the internal connection or interaction relationship of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0089] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is the orientation or positional relationship based on the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0090] The terms "first", "second", "third" (if any) in the description, claims and the above-mentioned drawings of this application are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of this application described herein can be implemented in an order other than those illustrated or described herein.

[0091] In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or display comprising a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or displays.

[0092] In the related art, a cleaning device has a handheld structure. The handheld structure includes a dust cup assembly and a main body assembly. The main body assembly is detachably connected to the device main body. The main body assembly and the dust cup assembly are usually directly connected and cooperated through a buckle structure. The main body assembly is used to provide suction force, and the dust cup assembly is used to collect the inhaled dust and dirt.

[0093] After the main body assembly is only connected to the dust cup assembly, it can also be used alone. At this time, a suction pipe or a floor brush and other accessories are also connected to one end of the dust cup assembly facing away from the main body assembly.

[0094] However, after the dust cup assembly is assembled with accessories, the accessories directly contact the cleaning surface, and the contact force is further transmitted to the buckle structure. The connection strength of the buckle structure is relatively low, so it is easy to break and fail after long-term stress. The connection reliability of the main body assembly and the dust cup assembly only relying on the buckle structure is poor, and the service life is short.

[0095] In view of the above problems, this application provides a handheld structure. By setting an installation seat, when the main body assembly and the dust cup assembly are connected and used separately, the installation seat is respectively connected to the main body assembly and the dust cup assembly, so as to disperse the stress at the connection of the main body assembly and the dust cup assembly, thereby improving the connection reliability of the main body assembly and the dust cup assembly.

[0096] The following will detail the specific implementation manners of the handheld structure provided by the embodiments of this application with reference to the accompanying drawings.

[0097] Refer to Figures 1 to 3As shown in the figure, the handheld structure provided by the embodiment of the present application includes a mounting base 100, a main unit assembly 200, and a dust cup assembly 300. The dust cup assembly 300 is detachably connected to the main unit assembly 200. The mounting base 100 includes a mounting base body, a main unit connector 110, and a dust cup connector 120. Both the main unit connector 110 and the dust cup connector 120 are connected to the mounting base body. The main unit assembly 200 is detachably connected to the main unit connector 110, and the dust cup assembly 300 is detachably connected to the dust cup connector 120.

[0098] It can be understood that a matching buckle 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. When the dust cup assembly 300 and the main unit assembly 200 are connected, they can be respectively connected to the mounting base 100 on the same side, that is, three mutually connected points, namely "dust cup assembly 300 - main unit assembly 200", "dust cup assembly 300 - mounting base 100", and "main unit assembly 200 - mounting base 100", are formed. Furthermore, when the main unit assembly 200 and the dust cup assembly 300 are used separately, the acting force between the original 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 buckle structure between the dust cup assembly 300 and the main unit assembly 200 is reduced, that is, the connection between the dust cup assembly 300 and the main unit assembly 200 is strengthened through the mounting base 100, and the connection reliability between the dust cup assembly 300 and the main unit assembly 200 is improved.

[0099] Among them, on the same side of the mounting base 100, a main unit connector 110 corresponding to the detachable connection of the main unit assembly 200 and a dust cup connector 120 corresponding to the detachable connection of the dust cup assembly 300 are fixedly arranged respectively. In this way, when specifically connecting, the main unit assembly 200 and the dust cup assembly 300 can be first connected, and then the connection body can be connected to the main unit connector 110 and the dust cup connector 120 correspondingly to realize the connection of both the main unit assembly 200 and the dust cup assembly 300 to the mounting base 100; or the main unit assembly 200 can be first connected to the main unit connector 110, and then the dust cup assembly 300 can be connected to the dust cup connector 120. And when the dust cup assembly 300 is connected to the dust cup connector 120, the dust cup assembly 300 is naturally connected to the main unit assembly 200 at the same time, and finally the connection of both the main unit assembly 200 and the dust cup assembly 300 to the mounting base 100 is realized. That is, the present application does not limit the installation sequence between the main unit assembly 200, the dust cup assembly 300, and the mounting base 100, nor is it necessary to limit it. It is only necessary to be able to use the mounting base 100 to improve the connection reliability between the main unit assembly 200 and the dust cup assembly 300.

[0100] Accordingly, the handheld structure provided by the embodiments of the present application realizes the connection between the host assembly 200 and the mounting base 100 by using the host connector 110 and the connection between the dust cup assembly 300 and the mounting base 100 by using the dust cup connector 120 through the provision of the mounting base 100 having the host connector 110 and the dust cup connector 120.

[0101] On the basis that the host assembly 200 and the dust cup assembly 300 are detachably connected to each other, the connection reliability between the host assembly 200 and the dust cup assembly 300 is strengthened by the separate connections of the mounting base 100 with the host assembly 200 and the dust cup assembly 300. In this way, the stress at the connection between the host assembly 200 and the dust cup assembly 300 can be dispersed to the mounting base 100, reducing the direct stress on the host assembly 200 and the dust cup assembly 300, thereby improving the connection reliability between the host assembly 200 and the dust cup assembly 300 and extending the service life of the connection between the host assembly 200 and the dust cup assembly 300.

[0102] And it should be noted that Figures 1 to 14 in, the X direction, Y direction, and Z direction shown are set such that any two of them are perpendicular to each other in the three-dimensional space. The mounting base 100 is disposed as a whole along the Y direction, wherein the dust cup assembly 300 and the host assembly 200 are distributed along the Z direction relative to the mounting base 100, and the dust cup assembly 300 and the host assembly 200 are distributed along the Y direction relative to each other, and both the dust cup assembly 300 and the host assembly 200 extend along the Y direction.

[0103] In some embodiments, referring to Figures 1 to 3 shown, the handheld structure further includes a latch assembly 400, and the host assembly 200 and the host connector 110 are connected or disconnected through the latch assembly 400.

[0104] It is easy to understand that the detachable connection between the host assembly 200 and the host connector 110 is realized by providing the latch assembly 400 between the host assembly 200 and the host connector 110. Furthermore, this avoids the direct clamping or plugging between the host assembly 200 and the host connector 110, and enables the connection and disconnection between the host assembly 200 and the host connector 110 to be more convenient and rapid.

[0105] And compared with the direct clamping or plugging between the host assembly 200 and the host connector 110, the latch assembly 400 has higher connection reliability, is also convenient for ensuring the stable and reliable connection between the host assembly 200 and the dust cup assembly 300, and has a longer service life.

[0106] In still other embodiments, referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 9As shown, the handheld structure further includes a locking assembly 500. One end of the dust cup assembly 300 facing away from the main machine assembly 200 is detachably connected to the dust cup connector 120 through the locking assembly 500.

[0107] In this way, by providing the locking assembly 500 between the dust cup assembly 300 and the dust cup connector 120, one end of the dust cup assembly 300 facing away from the main machine assembly 200 is connected to the dust cup connector 120, and one end of the dust cup assembly 300 close to the main machine assembly 200 is connected to the main machine assembly 200, so as to fix both ends of the dust cup assembly 300, ensure the reliability of the connection between the dust cup assembly 300 and the main machine assembly 200 and the mounting base 100, and make the overall structure of the handheld structure simpler and more compact.

[0108] In addition, in some embodiments, as shown in Figures 1 to 4 the mounting base 100 has an air duct 130, the dust cup assembly 300 has an air inlet 311, and the air duct 130 is communicated with the air inlet 311; the dust cup assembly 300 is communicated with the main machine assembly 200; the main machine assembly 200 has a first air outlet 211, and the mounting base 100 has at least one second air outlet 141, and the first air outlet 211 is communicated with the second air outlet 141.

[0109] It can be understood that by providing the air duct 130 communicated with the air inlet 311 of the dust cup assembly 300 and the second air outlet 141 communicated with the first air outlet 211 of the main machine assembly 200 on the mounting base 100, and the air duct 130 extends along Figure 2 the Y direction in the figure, and its extending direction is the same as that of the main machine assembly 200 and the dust cup assembly 300, so the air flow channel between the dust cup assembly 300 and the main machine assembly 200 can be extended through the mounting base 100 to form a complete air flow channel with both the inlet and outlet ports provided on the mounting base 100.

[0110] Furthermore, when the main machine assembly 200 and the dust cup assembly 300 are used separately relative to the handheld structure body, accessories such as a suction pipe or a dust 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 the direct contact and force between the dust cup assembly 300 and the cleaning surface through the accessories, improve the stability of the connection between the main machine assembly 200 and the dust cup assembly 300 and the mounting base 100 respectively, and further ensure the stable and reliable connection between the main machine assembly 200 and the dust cup assembly 300.

[0111] Moreover, compared with directly disposing the air duct 130 on the dust cup assembly 300 and enabling the accessory to be directly connected to the dust cup assembly 300 through the air duct 130, instead disposing the air duct 130 on the mounting base 100 can also make the air duct 130 farther away from the host assembly 200, increasing the distance between the host assembly 200 and the air inlet end of the air flow channel, so as to facilitate reducing the operating noise of the driving member in the host assembly 200 when the host assembly 200 and the dust cup assembly 300 are connected and used separately, and improving the use experience.

[0112] Further, in some embodiments, referring to Figures 1 to 8 as shown, the host assembly 200 includes a host body 210 and a host bottom cover 220. The host bottom cover 220 is disposed on the host body 210 and encloses a first accommodation cavity with the host body 210; the host connecting member 110 is disposed on the mounting base body and encloses a second accommodation cavity with the mounting base body; the locking component 400 is at least partially located in one of the first accommodation cavity and the second accommodation cavity to be clamped or disengaged from the host connecting member 110 or the host bottom cover 220 of the other.

[0113] It can be understood that the host body 210 and the host bottom cover 220 enclose the first accommodation cavity of the host assembly 200, and the host connecting member 110 and the mounting base 100 enclose the second accommodation cavity. Therefore, the outer wall structures of the first accommodation cavity and the second accommodation cavity along the Figure 3 Z direction shown can be set to be adapted, that is, the opposite sides of the host bottom cover 220 and the host connecting member 110 are adapted, so that when the host assembly 200 is connected to the mounting base 100, the host bottom cover 220 and the host connecting member 110 are more closely attached to ensure more reliable connection.

[0114] Wherein, the locking component 400 is disposed in the first accommodation cavity on one side of the host assembly 200 or in the second accommodation cavity on one side of the mounting base 100, and the locking component 400 partially protrudes from the accommodation cavity where it is located to be clamped or disengaged from the other, ensuring the stable connection between the host assembly 200 and the mounting base 100.

[0115] Moreover, since the setting position of the locking component 400 in the embodiments of the present application is not limited, the locking component 400 can be flexibly disposed on the one that is more convenient for installation operation or on the one that occupies less space and has stronger concealment according to specific use requirements and related structures, so as to make the structure of the handheld structure more compact and make the connection and disassembly between the host assembly 200 and the mounting base 100 more convenient and fast.

[0116] Wherein, since the host connecting member 110 is along Figure 3The Y direction is set at the rear side of the mounting base body, so that the host assembly 200 is also located at the rear part of the mounting base 100 along the Y direction. Furthermore, the dust cup connecting member 120 and the corresponding dust cup assembly 300 can be arranged at the front side of the mounting base 100 along the Y direction, so that the dust cup assembly 300 and the host assembly 200 are distributed front and back along the Y direction of the mounting base 100. In other embodiments, according to the specific connection form of the host assembly 200 and the dust cup assembly 300, for example, the host assembly 200 and the dust cup assembly 300 can be arranged side by side along the X direction, and the structure of the mounting base 100 can be correspondingly set. Then, according to the structure of the mounting base 100, appropriate components can be selected as the host connecting member 110 and the dust cup connecting member 120. The present application does not limit this.

[0117] In a possible embodiment, with reference to Figure 1 、 Figure 3 、 Figure 4 ,and Figures 10 to 14 as shown, the latch assembly 400 includes a latch bracket 410 and two first latches 420. Both of the two first latches 420 are connected to the latch bracket 410. The latch bracket 410 is configured to be partially located outside the second receiving cavity, and when pushed or pulled by an external force, it moves relative to the host bottom cover 220 in a first direction (such as Figure 13 and Figure 14 the direction indicated by the arrow in the Y direction in

[0118] ), and drives the two first latches 420 to approach each other, so that the first latches 420 are disengaged from the clamping connection with the host bottom cover 220, that is, controls the two first latches 420 to move in opposite directions along the X direction respectively.

[0119] It should be noted that the first direction can be the same as the direction indicated by the arrow in the Y direction or opposite to the direction indicated by the arrow in the Y direction. The present application does not limit this. Exemplarily, the latch bracket 410 can be set to move along the side (first direction) indicated by the arrow in the Y direction, and thereby drive the two first latches 420 to approach each other along the X direction respectively.

[0120] Wherein, the two first locks 420 are connected to the lock bracket 410, and the two first locks 420 can be moved at the same time through a push-pull action of the lock bracket 410, so that the lock assembly 400 is easy to operate, and the disassembly efficiency between the main assembly 200 and the main connector 110 is improved. In addition, the main assembly 200 and the main connector 110 are locked from two opposite directions in the X direction by the two first locks 420, forming a double locking, and the connection reliability between the main connector 110 and the main assembly 200 is also higher.

[0121] Further, continue to refer to Figure 1 、 Figure 3 、 Figure 4 ,and Figures 10 to 12 As shown, in some embodiments, the lock bracket 410 has a second lock 411, and the host bottom cover 220 has a snap groove 221 that matches the second lock 411; the second lock 411 is constructed to move with the lock bracket 410 and disconnect from the snap groove 221 synchronously with the first lock 420 perpendicularly.

[0122] Specifically, the second lock buckle 411 can be along Figure 10 The middle Y direction is set at the end of the lock bracket 410 away from the first lock 420, so that when the lock bracket 410 moves along the Y direction, it can drive the second lock 411 to move synchronously along the Y direction, and make the two first locks 420 move along the X direction under the drive of the lock bracket 410. It can be seen that the moving direction of the first lock 420 is perpendicular to the moving direction of the second lock 411.

[0123] Therefore, by setting a second lock 411 on the lock bracket 410, the second lock 411 can be used to form a third locking effect along a locking direction different from the first lock 420 on the basis of the double locking provided by the first lock 420, further strengthening the clamping effect between the lock assembly 400 and the main assembly 200, and thereby strengthening the reliability of the connection between the main assembly 200 and the mounting base 100.

[0124] In a specific implementation, the second lock buckle 411 may be fixedly connected to or integrally formed with the end of the lock buckle bracket 410 facing away from the first lock buckle 420 .

[0125] Furthermore, in some implementations of this embodiment, referring to Figure 1 、 Figure 4 、 Figure 13 and Figure 14As shown, the latch assembly 400 further includes a first reset member 430. A first mounting portion 111 is provided on the host connector 110, and a second mounting portion 412 is provided on the latch 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 such that when the latch bracket 410 moves in a first direction under an external force, it is compressed and deformed, so that the second latch 411 is disengaged from the buckle groove 221; when the external force on the latch bracket 410 is removed, the latch bracket 410 is driven to move in a second direction (for example Figure 13 and Figure 14 the reverse direction of the arrow in the Y direction in

[0126] ), to drive the second latch 411 to engage with the buckle groove 221, where the first direction is opposite to the second direction.

[0127] It can be understood that when the latch bracket 410 drives the first latch 420 to unlock the host assembly 200 and the host connector 110, it is also necessary to make the first latch 420 return to its initial position before unlocking, so as to facilitate the smooth progress of the next unlocking operation.

[0128] Therefore, by providing the first reset member 430, the latch bracket 410 is slidably connected to the host connector 110 through the first reset member 430. Since the first reset member 430 has the characteristics of compression and resilience, when it is necessary to lock and unlock the second latch 411 with the corresponding mounting portion, the user only needs to apply an external force to the latch bracket 410 once, which saves time and effort and is convenient to operate.

[0128] In a specific implementation, the first reset member 430 may be a helical 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 Figure 13 or Figure 14 the Y direction in Figure 13 or Figure 14 and is connected to the host connector 110 through the first mounting portion 111, and at the same time is connected to the latch bracket 410 through the second mounting portion 412. Therefore, when the latch bracket 410 moves relative to the host connector 110 along Figure 13 or Figure 14 the Y direction in Figure 13 or Figure 14 the first reset member 430 will be simultaneously pushed, so that the first reset member 430 is compressed and deformed along Figure 13 or Figure 14 the Y direction in Figure 13 or Figure 14 the Y direction in Figure 13 or Figure 14 When the external force on the latch bracket 410 is removed, the first reset member 430 can extend along the Y direction to restore the deformation, and drive the second latch 411 to reset in the reverse direction of the arrow in Figure 13 or Figure 14 the Y direction in

[0129] In addition, in some other embodiments, continue to refer toFigure 1 , Figure 4 , Figure 12 , Figure 13 and Figure 14 As shown in Figure 14 , the latch assembly 400 further includes a second reset member 440, and the two first latches 420 are connected by the second reset member 440; the second reset member 440 is configured to be compressed and deformed when the two first latches 420 approach each other; when the external force on the latch bracket 410 is released and the latch bracket 410 moves relative to the main body bottom cover 220 in the second direction, the two first latches 420 are driven to move away from each other so that both of the two first latches 420 are engaged with the main body bottom cover 220.

[0130] By providing mounting posts 423 along the Figure 12 X direction on the first latch 420 and providing a second reset member 440 extending along the X direction between the two mounting posts 423, when the external force driving the latch bracket 410 is released and the latch bracket 410 resets in the Y direction, the second reset member 440 can drive the two first latches 420 to move away from each other in the X direction and return to the initial position before unlocking. At this time, if the main body bottom cover 220 is aligned with the first connecting member, the first latch 420 can be further engaged with the main body bottom cover 220, so that the first latch 420 can perform the next disengaging and engaging operation more smoothly, improving the user experience of the handheld structure.

[0131] Similarly, in specific implementation, the second reset member 440 can also be set as a helical spring, so that the first reset member 430 and the second reset member 440 have better elastic properties and can drive the latch bracket 410 and the first latch 420 to reset more efficiently.

[0132] Specifically, referring to Figures 4 to 8 , and Figure 10 and Figure 12 As shown in Figure 12 , two opposite first mounting grooves 112 are provided on the main body connecting member 110, two opposite engaging grooves 222 are provided on the main body bottom cover 220, the first latch 420 has a latch portion 421, and the latch portions 421 are respectively engaged with or disengaged from the engaging grooves 222 through the first mounting grooves 112; a second mounting groove 113 is provided on the main body connecting member 110, and the latch bracket 410 is arranged in the second mounting groove 113.

[0133] Among them, the two first mounting grooves 112 are along the Figure 6The first locking hooks 420 are symmetrically distributed on both sides of the host connector 110 in the middle X direction to respectively accommodate the first locking hooks 420. A locking portion 421 is respectively provided on the opposite ends of the two first locking hooks 420. A notch that is compatible with the locking portion 421 is also provided on the opposite side of the first mounting groove 112. In this way, when the host connector 110 and the host bottom cover 220 are combined, the locking portion 421 can extend out of the first mounting groove 112 through the notch along the X direction and further extend into the two opposite engaging grooves 222 on the host bottom cover 220 to achieve the engaging connection between the first locking hooks 420 and the host bottom cover 220.

[0134] The host connector 110 is further provided with a second mounting groove 113 for accommodating the locking bracket 410. The second mounting groove 113 extends along the Y direction and is connected to the first mounting grooves 112 on both sides thereof, so as to facilitate the first locking buckle 420 to be respectively arranged on both sides of the locking bracket 410.

[0135] In this way, the first mounting slot 112 can accommodate the first locking latch 420, and the second mounting slot 113 can accommodate the locking latch bracket 410, thereby achieving installation of the locking latch assembly 400. Furthermore, the locking portion 421 on the first locking latch 420 engages with the engaging slot 222 of the host bottom cover 220, resulting in a relatively simple and compact structure that is easy to manufacture and facilitates ensuring a stable connection between the host connector 110 and the host assembly 200.

[0136] To improve the efficiency and stability of the connection, the host connector 110 is further provided with a first positioning block 115 and a second positioning block 116 facing the host bottom cover 220, and the host bottom cover 220 is provided with a first positioning groove 223 and a second positioning groove 224 that respectively adapt to the first positioning block 115 and the second positioning block 116. By providing the positioning block and the positioning groove structure in coordination, on the one hand, when the host assembly 200 is placed on the mounting base 100, the positioning can be more quickly and accurately improved, thereby improving the efficiency of the connection between the locking assembly 400 and the host bottom cover 220. On the other hand, after the host assembly 200 is connected to the mounting base 100, it can prevent the host assembly 200 from moving or shaking on the mounting base 100, thereby improving the stability of the connection between the locking assembly 400 and the host bottom cover 220. Furthermore, the first positioning block 115 can be set as a hollow block protruding toward the first positioning groove 223, and the first installation groove 112 can be correspondingly set in the hollow interior of the first positioning block 115 away from the first positioning groove 223 to make the overall structure more compact.

[0137] Further, refer to Figures 10 to 14As shown, two guide bars 413 are symmetrically arranged on the lock bracket 410, and a slot 422 is provided on each of the two first locks 420. The slots 422 are respectively correspondingly arranged on the guide bars 413, and the surfaces opposite to the slots 422 and the guide bars 413 are matching inclined surfaces; the guide bars 413 are constructed to slide correspondingly relative to the first locks 420 to drive the two first locks 420 away from or closer to each other.

[0138] Specifically, by setting the contact surface between the card slot 422 and the guide bar 413 as a matching first inclined surface 4221 and a second inclined surface 4131, when the lock bracket 410 moves, the inclined surface feature will form a certain thrust on the first lock 420, and guide the movement direction of the first lock 420 after being subjected to force.

[0139] For example, the guide strip 413 is partially along Figure 11 The guide bar 413 extends in the Y direction and is partially inclined toward the X direction, extending in a direction between the X and Y directions to form a second inclined surface 4131. The locking slot 422 is provided with a first inclined surface 4221 that matches the second inclined surface 4131. When the locking bracket 410 moves in the Y direction, the guide bar 413 moves synchronously with the locking bracket 410 in the Y direction. Since the first inclined surface 4221 on the guide bar 413 and the second inclined surface 4131 on the locking slot 422 interact with each other, the locking slot 422 moves in the X direction relative to the guide bar 413.

[0140] Through the above-mentioned arrangement, the structure of the first lock 420 and the lock bracket 410 can be made simpler and easier to manufacture. After the two are connected, the lock structure as a whole is small and compact, does not take up too much space, and is convenient for users to use.

[0141] And in some embodiments, reference Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 10 、 Figure 11 and Figure 13 As shown, a paddle 414 is provided on the lock bracket 410 , and the paddle 414 is located on a side of the lock bracket 410 facing away from the second lock, and a portion of the paddle 414 is located outside the second accommodating cavity.

[0142] Pick 414 along Figure 11 The middle Z direction is set on the side of the lock bracket 410 away from the second lock, and when the lock bracket 410 is set in the second installation groove 113, the paddle 414 can extend out of the second installation groove 113 and further be located outside the second accommodating cavity.

[0143] The paddle 414 is partially disposed outside the second receiving cavity, which facilitates the user to apply an external force to the paddle 414 from the side of the mounting base 100 opposite to and away from the host assembly 200, so as to drive the paddle 414 to move in the Y direction, and further drive the latch bracket 410 to move by the paddle 414, simplifying the unlocking operation of the latch assembly 400.

[0144] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 9 as shown, a dust cup mounting groove 121 is provided on the dust cup connector 120, and one end of the dust cup assembly 300 away from the host assembly 200 is snap-connected or disengaged from the dust cup mounting groove 121 through the locking assembly 500.

[0145] In this way, it is convenient to use the mutual cooperation between the dust cup mounting groove 121 and the locking assembly 500 to realize the installation of the dust cup assembly 300. The whole is linearly arranged along the Figure 4 Y direction in the figure, with a simple structure and stable and reliable connection.

[0146] The dust cup connector 120 has an arc-shaped fitting surface extending in the Y direction, through which the connection between the dust cup assembly 300 and the dust cup connector 120 can be made more stable and fitting.

[0147] And in some embodiments, continue to refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 9 as shown, the locking assembly 500 includes a locking member 510 and a locking groove. One of the locking member 510 and the locking groove is located on the dust cup connector 120, and the other is located at one end of the dust cup assembly 300 away from the host assembly 200, and the locking member 510 is connected or disconnected from the locking groove.

[0148] By respectively providing the locking member 510 and the locking groove on the dust cup assembly 300 and the dust cup connector 120, it is convenient to use the snap-fit between the locking member 510 and the locking groove, with a simple structure, to realize the snap connection between the dust cup assembly 300 and the dust cup connector 120.

[0149] Moreover, the locking assembly 500 is disposed at one end of the dust cup assembly 300 away from the host assembly 200, which can avoid interference between the locking assembly 500 and the latch assembly 400, and enable the locking assembly 500 and the host assembly 200 to respectively fix the dust cup assembly 300 from both ends of the dust cup assembly 300, so as to ensure that the operation of the locking assembly 500 is simple and the stability of the installation of the dust cup assembly 300 is relatively high.

[0150] And, in some embodiments, continue to refer to Figure 1 , Figure 2 ,Figure 3 , Figure 4 and Figure 9 As shown in Figure 3 , Figure 4 and Figure 9 , a lock groove is formed in the dust cup mounting groove 121. A locking groove 312 is provided at one end of the dust cup assembly 300 facing away from the host assembly 200. The locking member 510 is disposed in the locking groove 312 and moves relative to the locking groove 312 to insert into or withdraw from the locking groove 312.

[0151] The locking member 510 is engaged with the lock groove along Figure 3 the Y direction in Figure 3 . In this way, when it is necessary to unlock the locking assembly 500, an external force can be applied to the locking member 510, so that the locking member 510 moves relative to the locking groove 312 along the Y direction. While at least partially inserted into the locking groove 312, it withdraws from the lock groove to disengage from the lock groove engagement.

[0152] In this way, the dust cup mounting groove 121 can be used as a lock groove, saving the number of holes and grooves on the dust cup connecting member 120, simplifying the structure of the dust cup connecting member 120 and making it more convenient for processing. The locking member 510 is disposed in the locking groove 312, and the dust cup assembly 300 is unlocked by moving relative to the locking groove 312, which also facilitates further simplifying the unlocking operation of the locking assembly 500.

[0153] Further, referring to Figure 3 and Figure 4 as shown, the locking assembly 500 further includes a locking bracket 530 and a third reset member 520. The locking bracket 530 is disposed in the locking groove 312. The locking member 510 is connected to the locking bracket 530 through the third reset member 520. The locking member 510 is configured such that when pressed by an external force, it drives the third reset member 520 to be compressed and deformed, so as to move toward the locking bracket 530, thereby inserting into the locking groove 312. The third reset member 520 is configured such that when the external force on the locking member 510 is released, it restores its deformation to drive the locking member 510 to partially withdraw from the locking groove 312.

[0154] Among them, the locking assembly 500 is integrally disposed in the locking groove 312 through the locking bracket 530. The third reset member 520 can be the same helical spring as the first reset member 430 and the second reset member 440. The third reset member 520 is disposed along the Y direction, with one end abutted against the locking member 510 and the other end abutted against the locking bracket 530. In this way, the movable connection between the locking member 510 and the locking bracket 530 can be realized through the third reset member 520.

[0155] When the locking member 510 is pressed into the locking groove 312 by an external force to unlock the dust cup assembly 300, the third reset member 520 is pressed by the external force and deformed by compression. When the external force is removed, the third reset member 520 extends by itself to drive the locking bracket to reset in the Y direction and at least partially protrude from the locking groove 312. When the dust cup assembly 300 is engaged with the dust cup connecting member 120, the locking member 510 is engaged with the dust cup mounting groove 121, simplifying the operation of the locking assembly 500 and improving the user experience.

[0156] And since the end of the dust cup connecting member 120 facing away from the host connecting member 110 is provided with an inclined protrusion, the dust cup mounting groove 121 can be arranged at the inclined protrusion, and an avoidance groove adapted to the inclined protrusion is arranged on the dust cup assembly 300, so that the connection between the dust cup assembly 300 and the mounting seat 100 is more tightly and reliably.

[0157] In addition, in some embodiments, referring to Figures 2 to 4 As shown, the mounting seat body includes a mounting seat front shell 140 and a mounting seat rear shell 150. The mounting seat rear shell 150 is connected to the mounting seat front shell 140, and the mounting seat rear shell 150 is connected to the side of the host connecting member 110 facing away from the host assembly 200.

[0158] In this way, by setting the mounting seat rear shell 150 and the mounting seat front shell 140 to be detachably connected, it is convenient to flexibly install other parts or open other hole groove structures between the mounting seat rear shell 150 and the mounting seat front shell 140, so that the overall structure of the mounting seat 100 is more comprehensive.

[0159] A mounting seat bottom shell 160 connected to the mounting seat front shell 140 and the mounting seat rear shell 150 can also be provided to improve the structural stability of the mounting seat 100.

[0160] Furthermore, referring to Figures 1 to 4 As shown, a receiving groove 142 is provided on the mounting seat front shell 140. The air duct 130 is located in the receiving groove 142. The dust cup connecting member 120 is provided on the mounting seat front shell 140. The dust cup connecting member 120 and the host connecting member 110 jointly cover the receiving groove 142.

[0161] In this way, by jointly covering the receiving groove 142 by the dust cup connecting member 120 and the host connecting member 110, the air duct 130 can be more stably located in the receiving groove 142, and the fixing components of the air duct 130 can be saved, making the structure of the mounting seat 100 simple and compact.
