[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese patent application No. 202311483357.5, filed on November 8, 2023, entitled “Vacuum cleaner assembly and its pipe attachment”, and Chinese patent application No. 202323020654.4, filed on November 8, 2023, entitled “Vacuum cleaner assembly and its pipe attachment”, the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0003] The present disclosure relates to the technical field of cleaning equipment, and in particular to a pipe attachment and a vacuum cleaner assembly including the pipe attachment. Background Art

[0004] Vacuum cleaners are compatible with a variety of accessories to suit different scenarios. For example, when using a floor brush to clean the floor, a connecting pipe accessory is generally used to connect the floor brush to the vacuum cleaner body. Another example is when using a flat suction piece to clean corners such as curtains, tables, and gaps, the flat suction piece is connected to the vacuum cleaner body.

[0005] However, in one technology, the flat suction and the connecting pipe are separated as two accessories, which will cause users to switch accessories back and forth in different scenarios. For example, when cleaning the floor and then cleaning the sofa, coffee table and other surfaces, it is necessary to remove the connecting pipe accessory and the floor brush from the vacuum cleaner host and replace them with the flat suction piece connected to the vacuum cleaner host. In addition, since users may often use the connecting pipe to connect the floor brush when cleaning the floor, but seldom use the flat suction piece, they may not be able to find the flat suction piece when they want to use it, or the flat suction piece takes up space in the home because it is not often used, and it is troublesome to store it.

DETAILED DESCRIPTION

[0085] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0086] As shown in Figure 1, the pipe attachment 10 of the vacuum cleaner assembly 100 according to the embodiment of the present disclosure includes a first fitting 11. The first fitting 11 includes a suction portion 111 and a brushing portion 112. The suction portion 111 can be used to clean gaps, corners and narrow areas. The brushing portion 112 can be used to clean countertops, surfaces and other areas to avoid scratching the countertops while cleaning. The brushing portion 112 can move on the suction portion 111. The first fitting 11 also includes a first connecting portion 113, which can be connected to the vacuum cleaner body 20. The first fitting 11 can be used as a separate accessory and connected to the vacuum cleaner body 20 when in use.

[0087] The take-over accessory 10 also includes a second fitting 12, which may include a rod 121 and a second connecting portion 122. The second connecting portion 122 is used to releasably connect the second fitting 12 to the first fitting 11. The take-over accessory 10 formed after the second fitting 12 is connected to the first fitting 11 can be used as a part of connecting the vacuum cleaner main body 20 and the floor brush 30. Generally, as a separate accessory, one end of the take-over accessory 10 can have a connector portion (i.e., the first connecting portion 113) connected to the vacuum cleaner main body 20, and the other end can have a connector portion connected to the floor brush 30. Here, as a separate accessory, the connection between one end of the take-over accessory 10 and the vacuum cleaner main body 20 can be direct or indirect. If it is a direct connection, the first connecting portion 113 is docked with the air inlet of the vacuum cleaner main body. If it is an indirect connection, other connecting pipes or connecting parts are provided between the first connecting portion 113 and the air inlet of the vacuum cleaner main body. Similarly, the connection between the other end of the take-over accessory 10 and the floor brush can also be direct or indirect.

[0088] When cleaning the floor, the user can connect the vacuum cleaner body 20 to the floor brush 30 via the connecting pipe attachment 10. When cleaning a tabletop, the user generally uses the brushing function of the sweeping portion 112 of the first fitting 11. When cleaning the gap between a seat and backrest or other gaps, the user generally uses the suction portion 111 of the first fitting 11. Therefore, in the connecting pipe attachment 10 of the present disclosure, the first fitting 11 can be used alone as a flat suction member or a brushing attachment. The first fitting 11 and the second fitting 12 can be combined to form a complete connecting pipe attachment 10 that connects to the floor brush 30 to clean the floor area to be cleaned.

[0089] When the second fitting 12 is connected to the first fitting 11, at least a portion of the brushing portion 112 can be positioned outside the second fitting 12. Furthermore, at least a portion of the suction portion 111 can be positioned inside the second fitting 12. When the second fitting 12 is connected to a cleaning tool such as a floor brush, the first fitting 11 and the brushing portion 112 in the first fitting 11 can be assembled together to form the pipe attachment 10, thereby avoiding the problem of having nowhere to place or being easily lost after the components are removed.

[0090] In the present disclosure, at least a portion of the suction part 111 is arranged inside the second fitting 12, which can facilitate the airflow to circulate between the first fitting 11 and the second fitting 12, and facilitate the use of the pipe attachment 10; at least a portion of the brushing part 112 is arranged outside the second fitting 12, which can facilitate the user to intuitively view the brushing part 112 and remind the user of the position of the brushing part 112. When it is necessary to switch to using the brushing part 112 for cleaning, there is no need to look for it elsewhere.

[0091] Furthermore, disposing at least a portion of the brush portion 112 outside the second mating member 12 can also prevent the brush portion 112 from getting stuck on the second mating member 12, making it difficult to separate the brush portion 112 from the second mating member 12. Specifically, if garbage or the like gets stuck between the brush portion 112 and the second mating member 12 during cleaning, making it difficult to separate the brush portion 112 from the second mating member 12, the brush portion 112 can be separated from the second mating member 12 by applying forces in opposite directions to the portion of the brush portion 112 disposed outside the second mating member 12 and the second mating member 12, respectively.

[0092] According to the pipe connection accessory 10 of the vacuum cleaner assembly 100 of the embodiment of the present disclosure, the first fitting 11 can be used as a part of the pipe connection accessory 10 when the user does not use the flat suction function, and can be assembled with the second fitting 12 for use, without affecting the installation and use of the second fitting 12. It also avoids the need to remove the first fitting 11 or the brushing part 112 and find another place to place it when installing the second fitting 12. The pipe connection accessory 10 is easy to use and avoids the problem of existing flat suction parts being easily lost due to non-use; when in use, the first fitting 11 can adjust the working mode to adapt to different scenarios by moving the brushing part 112; the position of the brushing part 112 can be conveniently displayed, and the brushing part 112 can be conveniently separated from the second fitting 12.

[0093] In some embodiments of the present disclosure, the first mating member 11 and / or the second mating member 12 are provided with a locking hook that secures the first mating member 11 and the second mating member 12 together. A positioning groove can be provided on the suction portion 111, and a locking hook can be provided on the second mating member 12. As shown in FIG3 , when the second mating member 12 is connected to the first mating member 11, the locking hook can be inserted into the positioning groove to achieve a stable fit between the second mating member 12 and the first mating member 11. The second mating member 12 can also be unlocked from the first mating member 11 by disengaging the locking hook from the positioning groove. As shown in FIG4 , the positioning groove can be the second positioning groove described in the following embodiments, but other grooves are also acceptable.

[0094] As shown in Figures 1 and 2, in some embodiments of the present disclosure, when the second mating member 12 is connected to the first mating member 11, the second mating member 12 and at least a portion of the brushing portion 112 are axially opposed to each other along the suction portion 111. During the removal of the second mating member 12 from the first mating member 11, forces can be applied to the brushing portion 112 and the second mating member 12 in opposite directions along the suction portion 111, respectively, to quickly separate the brushing portion 112 from the second mating member 12, facilitating quick removal of the second mating member 12. Therefore, the present disclosure can improve the efficiency of assembly and disassembly of the brushing portion 112 and the second mating member 12.

[0095] Furthermore, since the second mating member 12 and the brushing portion 112 are axially opposed, when the second mating member 12 is installed, the second mating member 12 can abut against the brushing portion 112 on the first mating member 11, thereby moving the brushing portion 112 from the working position to the storage position. The second mating member 12 and the brushing portion 112 in the present disclosure can also be configured in a sleeve-type connection, for example, by configuring at least a portion of the brushing portion 112 to surround the second mating member 12.

[0096] In some embodiments of the present disclosure, when the second mating member 12 is connected to the first mating member 11, at least a portion of the brushing portion 112 is located between the second mating member 12 and the first connecting portion 113. The second mating member 12 and the first connecting portion 113 can be used to limit the brushing portion 112 to a predetermined position, thereby improving the stability of the connection between the first mating member 11 and the second mating member 12 and facilitating the connection of the first connecting portion 113 to the cleaner body 20.

[0097] As shown in Figures 5 and 6, one end of the brushing portion 112 is provided with a mating groove 1103. When the second mating member 12 is connected to the first mating member 11, the second connecting portion 122 extends into the mating groove 1103. This ensures a stable connection between the second mating member 12 and the brushing portion 112, facilitates positioning of the second mating member 12, prevents the second mating member 12 from damaging the bristles and other cleaning structures 1122 on the brushing portion 112, and prevents the second mating member 12 from scratching the outer surface of the brushing portion 112, thus facilitating the handling and use of the pipe attachment 10. Furthermore, the second connecting portion 122 may also have a curved step. After the first and second mating members 11 and 12 are engaged, the protruding portion of the step is located in the mating groove 1103. When the first and second mating members 11 and 12 are assembled together, the outer surface of the brushing portion 112 and the outer wall of the second mating member 12 together constitute the outer surface of the pipe attachment 10, and the inner wall of the suction portion 111 and the inner wall of the rod 121 together form the suction channel of the pipe assembly.

[0098] In addition, in conjunction with the above, the second mating member 12 can include a rod 121 and a second connecting portion 122. The second connecting portion 122 can surround the suction portion 111 and face the brushing portion 112 along the axial direction of the suction portion 111. The second connecting portion 122 can extend into the mating groove 1103. The rod 121 can be sleeved onto the suction portion 111. In this way, the suction portion 111 and the brushing portion 112 can be used to position the second mating member 12, effectively improving the assembly efficiency and stability of the second mating member 12 and the first mating member 11.

[0099] The brushing portion 112 can be mounted on the outer periphery of the suction portion 111. This allows the brushing portion 112 to be configured to move axially along the suction portion 111 to adjust its position relative to the suction portion 111. Specifically, the suction portion includes a suction port, and the brushing portion is mounted on the outer periphery of the suction portion and can move between the suction port and the first connecting portion 113. The brushing portion 112 can have a working position and a storage position. When the brushing portion 112 is in the working position, the cleaning structure 1122 thereon can extend out of the suction portion 111 to facilitate brushing the work surface. When the brushing portion 112 is in the storage position, the brushing portion 112 extends out of the suction portion 111, allowing it to connect to the second mating component 12 or to suck dust from gaps. Furthermore, when the second mating component 12 is connected to the first mating component 11, the second connecting portion 122 is mounted on the suction portion 111.

[0100] As shown in Figures 13 to 15 , the brushing unit 112 includes a main structure 1121 and a cleaning structure 1122 connected to the main structure 1121. The cleaning structure 1122 can be used to clean a working area on a first flat surface 1103, such as a desktop. When the second fitting 12 is connected to the first fitting 11, the first fitting 12 abuts against the brushing unit along the axial direction of the suction unit, and at least a portion of the main structure 1121 is located outside the second fitting 12. Furthermore, when the second fitting 12 is connected to the first fitting 11, at least a portion of the cleaning structure 1122 can be located inside the second fitting 12. This prevents damage to the cleaning structure 1122 during installation of the second fitting 12 to the first fitting 11, and allows the cleaning structure 1122 to be protected by the second fitting 12, thereby improving the stability of the brushing unit 112, maintaining the stability of the cleaning structure 1122, and facilitating its use.

[0101] As shown in FIG14 , in some embodiments, the main structure 1121 includes an outer shell 11211 and an inner shell 11212. The outer shell 11211 surrounds the inner shell 11212. The cleaning structure 1122 is connected to one end of the inner shell 11212. One end of the outer shell 11211 extends out of the inner shell 11212 and surrounds the cleaning structure 1122. The outer shell 11211 can provide protection for the cleaning structure 1122, preventing the cleaning structure 1122 from excessive bending, thereby extending the service life of the cleaning structure 1122. Specifically, the cleaning structure 1122 can be bristles, which are fixedly connected to the inner shell 11212, with a portion of the bristles located inside the outer shell 11211 and another portion extending out of the outer shell 11211. In this way, when the bristles bend during cleaning, the portion extending out of the outer shell 11211 also bends, thereby preventing the bristles from excessive bending and ensuring the service life of the bristles.

[0102] When the second fitting member 12 is connected to the first fitting member 11, the second connecting portion 122 abuts against one end of the inner shell, which facilitates the stable matching of the second fitting member 12 and the sweeping portion 112 and maintains the stability of the second fitting member 12 and the first fitting member 11 after assembly.

[0103] As shown in Figure 14, in some embodiments, an annular rib 11213 is provided at one end of the inner shell 11212. The annular rib 11213 surrounds the cleaning structure 1122. When the second mating member 12 is connected to the first mating member 11, the second connecting portion 122 extends between the outer shell 11211 and the annular rib 11213. The mating of the annular rib 11213 with the outer shell 11211 facilitates the mating of the sweeping portion 112 with the second mating member 12, improving the stability of the mating relationship between the second mating member 12 and the sweeping portion 112. This mating relationship also reduces air leakage, improves energy efficiency, and contributes to energy conservation and environmental protection.

[0104] As shown in Figure 14, in some embodiments, the second connecting portion 122 of the present disclosure can be constructed with a flared structure, which can facilitate the placement of the cleaning structure 1122. When the second fitting 12 is connected to the first fitting 11, the flared structure is opposite to the main structure 1121 along the length of the suction portion 111 and surrounds the cleaning structure 1122. Specifically, the second connecting portion 122 is connected to the rod 121, and the second connecting portion 122 is constructed in a flared form in a direction away from the rod 121. In this way, the cleaning structure 1122 can be surrounded by the second connecting portion 122, and the stable fit of the rod 121 and the suction portion 111 can be facilitated. The opening of the second connecting portion 122 can be opposite to the outer shell 11211 along the axial direction of the suction portion 111.

[0105] Specifically, at least a portion of the second connecting portion 122 gradually increases in size as it moves away from the rod 121. When the second fitting 12 is assembled with the first fitting 11, the suction portion 111 can be inserted into the rod 121, ensuring a stable fit between the suction portion 111 and the rod 121. The second connecting portion 122 can also mate with the brushing portion 112, ensuring a stable fit between the two. Furthermore, the second connecting portion 122 can conveniently accommodate the cleaning structure 1122, preventing it from affecting the performance of the cleaning structure 1122 during assembly. Specifically, as shown in Figure 17, when the second fitting 12 is connected to the cleaner body 20, the rod 121 is sleeved onto the suction portion 111.

[0106] As shown in Figures 7 to 12, in some embodiments of the present disclosure, the brush sweeping portion 112 has a working position (as shown in Figures 7 to 9) and a storage position (as shown in Figures 10 to 12). The suction portion has a suction port, and the brush sweeping portion 112 is unfolded relative to the suction portion 111 in the working position, and the brush sweeping portion protrudes from the suction port. Specifically, in combination with the foregoing, the cleaning structure protrudes from the suction port. The brush sweeping portion 112 is locked with the suction portion 111 in the working position. The brush sweeping portion 112 is retracted relative to the suction portion 111 in the storage position, or in other words, the brush sweeping portion 112 is away from the suction port in the storage position. When the brush sweeping portion 112 is in the working position, the cleaning structure 1122 can be configured to extend out of the end of the suction portion 111 to facilitate cleaning the working surface. Specifically, in combination with the foregoing, the cleaning structure 1122 of the brush sweeping portion 112 extends out of the end of the suction portion 111. When the suction part 111 is needed to perform suction, or when the second fitting 12 needs to be connected to the first fitting 11, the brushing part 112 can be moved to the storage position. In this way, the brushing part 112 can be prevented from affecting the connection between the second fitting 12 and the first fitting 11. At the same time, the end of the suction part 111 can be used for suction, and the suction part 111 can be used to clean gaps and narrow corners; when the brushing part 112 is needed, the brushing part 112 can be moved to the working position, and the cleaning structure 1122 (such as bristles) of the brushing part 112 can extend out of the end of the suction part 111, so that the cleaning structure 1122 can be used to clean the working surface, which can be used to clean countertops, surfaces and other areas, avoiding scratching the countertop while cleaning. At the same time, during the brushing process of the brushing part 112, suction can be performed through the suction part 111 to remove dust.

[0107] To facilitate installation of the second mating member 12, the brushing portion 112 can be moved to the storage position when the second mating member 12 is mounted on the first mating member 11. For example, the brushing portion 112 can be moved to the storage position before the second mating member 12 is connected to the first mating member 11; alternatively, the brushing portion 112 can be unlocked by the second mating member 12 when the second mating member 12 is connected to the first mating member 11, and then driven to move to the storage position after unlocking.

[0108] In some embodiments of the present disclosure, when the second mating member 12 is connected to the first mating member 11, if the brushing portion 112 is in the working position, the second mating member 12 can drive the brushing portion 112 and the suction portion 111 to unlock and move the brushing portion 112 to the storage position. In this way, when the second mating member 12 is connected to the first mating member 11, there is no need to move the brushing portion 112 to the storage position in advance. Instead, the second mating member 12 can be directly connected to the first mating member 11, thereby improving the assembly efficiency of the second mating member 12 and the first mating member 11.

[0109] In some embodiments of the present disclosure, the first mating component 11 further includes a pressing member 1123, which can be used to unlock the first mating component 11. Specifically, the pressing member 1123 is provided on the brushing portion 112 and is used to move under the action of the second connecting portion to release the lock of the brushing portion 112 and the suction portion 111. In other words, when an external force drives the pressing member 1123, the pressing member 1123 will unlock the brushing portion 112 and the suction portion 111. When it is necessary to unlock the brushing portion 112 and the suction portion 111, an external force can be applied to the pressing member 1123 to utilize the pressing member 1123 to unlock the brushing portion 112 and the suction portion 111. The external force can come from the force applied by the second connecting portion 122 to the pressing member 1123 when the second mating component 12 is connected to the first mating component 11, or it can be an external force generated in other forms (such as manual pressing, electronically controlled driving, etc.).

[0110] For example, when the second fitting 12 is connected to the first fitting 11, it can drive the extrusion member 1123 in the working position to unlock the brushing portion 112 and the suction portion 111, and drive the brushing portion 112 to the storage position. In this way, when the pipe attachment 10 switches from using the brushing portion 112 to clean the work surface to using the pipe attachment 10 to clean the work surface, the second fitting 12 can be directly installed on the first fitting 11, facilitating the rapid assembly of the second fitting 12 and the first fitting 11, and improving the assembly efficiency and stability of the pipe attachment 10.

[0111] In some embodiments, the pressing member 1123 is configured to unlock the brushing portion 112 and the suction portion 111 when moving along a first direction, where the first direction is a direction in which the brushing portion 112 moves from the working position to the storage position. When the second fitting part 12 is installed on the first fitting part 11, the brushing part 112 will move from the working position to the storage position. The aforementioned first direction is the direction in which the suction part 111 moves from the working position to the storage position, and it is also the installation direction of the second fitting part 12 relative to the first fitting part 11. That is to say, in the process of the second fitting part 12 connecting to the first fitting part 11, the second connecting part 122 on the second fitting part 12 will move along the first direction. Therefore, in the process of the second fitting part 12 being installed on the first fitting part 11, it will be transmitted and matched with the extrusion part 1123 on the brushing part 112 in the working position, and drive the extrusion part 1123 to move to release the lock of the brushing part 112 and the suction part 111. At this time, the brushing part 112 can move relative to the suction part 111, so that the second fitting part 12 can continue to be installed, and at the same time, the second fitting part 12 drives the brushing part 112 to move to the storage position. The second matching piece 12 and the first matching piece 11 are assembled smoothly. No matter whether the brushing portion 112 is in the working position or the storage position, the second matching piece 12 can be smoothly connected to the first matching piece 11, and the operation is convenient.

[0112] The second mating member 12 also includes a first restoring member (not shown in the figure). The first restoring member is provided on the brushing portion 112 and applies an elastic force to the extruding member 1123 along a second direction, which is the direction in which the brushing portion 112 moves from the storage position to the working position. When the extruding member 1123 is acted upon by an external force, it can unlock the brushing portion 112 and the suction portion 111. When the external force is removed, the first restoring member can reset the extruding member 1123, restoring the extruding member 1123 to its state before the external force was applied. At this point, the extruding member 1123 no longer unlocks the brushing portion 112 and the suction portion 111, and prepares for the next external force to drive the extruding member 1123.

[0113] In conjunction with the foregoing, the brushing portion 112 can be locked with the suction portion 111 when in the working position. Therefore, a locking portion 1124 is provided in the present disclosure to lock the brushing portion 112 and the suction portion 111. As shown in Figures 8 and 9, in some embodiments of the present disclosure, the first mating member 11 further includes a locking portion 1124, which is used to lock and unlock the brushing portion 112 and the suction portion 111. The locking action of the locking portion 1124 can restrict the movement of the brushing portion 112 relative to the suction portion 111. In other words, the locking portion 1124 has a locked state and an unlocked state. When the locking portion 1124 is in the locked state, the brushing portion 112 and the suction portion 111 are locked, and the brushing portion 112 is stationary relative to the suction portion 111 and cannot move. When the locking portion 1124 is in the unlocked state, the brushing portion 112 and the suction portion 111 are unlocked.

[0114] 8 and 9 , in FIG8 , the locking portion 1124 extends into the first positioning slot, locking the brushing portion 112 and the suction portion 111. At this time, the brushing portion 112 is in the working position. In FIG9 , the locking portion 1124 is released from the first positioning slot, unlocking the brushing portion 112 and the suction portion 111. At this time, the brushing portion 112 can move on the suction portion 111. In addition, in other embodiments of the present disclosure, the locking portion 1124 can also be locked in the storage position. In FIG11 , the locking portion 1124 extends into the second positioning slot, locking the brushing portion 112 and the suction portion 111. At this time, the brushing portion 112 is in the storage position. In FIG11 , the locking portion 1124 is released from the second positioning slot, unlocking the brushing portion 112 and the suction portion 111.

[0115] In addition, in combination with the above, the extruding member 1123 is in transmission cooperation with the locking portion 1124. By the transmission cooperation between the extruding member 1123 and the locking portion 1124, when the extruding member 1123 is subjected to an external force, the locking portion 1124 can be driven to unlock the brushing portion 112 and the suction portion 111. In other words, when the extruding member 1123 is subjected to an external force, the locking portion 1124 can be driven to switch to an unlocked state, at which time the brushing portion 112 is movable relative to the suction portion 111. The combination of the locking portion 1124 and the extruding member 1123 ensures stable cooperation between the brushing portion 112 and the suction portion 111, and can quickly unlock the brushing portion 112 and the suction portion 111 when the extruding member 1123 is subjected to an external force, thereby facilitating use.

[0116] The locking portion 1124 is rotatably connected to the brushing portion 112. The locking portion 1124 comprises a wedge-shaped structure 11242 and a locking structure 11243, respectively, disposed on either side of the rotation axis. The locking structure 11243 is used to lock the brushing portion 112 and the suction portion 111. The extrusion member 1123 is in driving engagement with the wedge-shaped structure 11242 and is adapted to press the wedge-shaped structure 11242 to unlock the brushing portion 112 and the suction portion 111. The extrusion member 1123 can be configured to move in the direction (a first direction or a second direction) in which the brushing portion 112 moves relative to the suction portion 111. This is the same direction in which the second mating member 12 is connected to the first mating member 11. Therefore, when the second mating member 12 is connected to the first mating member 11, the extrusion member 1123 can be driven to move in the first direction. When the extrusion member 1123 moves along the first direction, it can cooperate with the wedge structure 11242 to drive the wedge structure 11242 to form a pressing action. At the same time, since the wedge structure 11242 and the locking structure 11243 are respectively arranged on both sides of the rotating shaft, the action of pressing the wedge structure 11242 will lift the locking structure 11243. At this time, the locking structure 11243 will release the lock on the suction part 111 and the brushing part 112, thereby achieving the purpose of unlocking the suction part 111 and the brushing part 112.

[0117] In conjunction with the aforementioned embodiment, the brushing portion 112 includes a mating groove at one end, wherein a portion of the extruding member 1123 can be extended into the mating groove. When the second mating member 12 is connected to the first mating member 11, the second connecting portion extends into the mating groove and drives the extruding member 1123. This facilitates the extruding member 1123 to be actuated by the second mating member 12, driving the extruding member 1123 to move, thereby achieving the purpose of unlocking the brushing portion 112 and the suction portion 111.

[0118] In addition, in some other examples of the present disclosure, the brushing portion 112 and the suction portion 111 can be locked by various methods such as interference fit, snap fit, and locking with a locking member, and the corresponding brushing portion 112 and the suction portion 111 can also be unlocked by various methods. For example, if the brushing portion 112 and the suction portion 111 are locked by interference fit, the brushing portion 112 can be unlocked by applying an external force to the brushing portion 112; when the brushing portion 112 and the suction portion 111 are snap fit, the unlocking can be achieved by releasing the snap fit; when locked by a locking member, the unlocking can be achieved by pressing, electric control, etc. The following disclosure provides a solution for locking and unlocking the brushing portion 112 and the suction portion 111 by using a locking member, but this does not limit the scope of protection of the present disclosure.

[0119] According to the pipe attachment 10 of the embodiment of the present disclosure, when the brushing part 112 is in the working position, the locking part 1124 on the brushing part 112 is locked with the first positioning groove 1101 of the suction part 111. At this time, if the first matching part 11 and the second matching part 12 are to be installed together, the locking structure must be unlocked before the suction part 111 can be inserted into the second matching part 12. For this purpose, the discloser has designed an unlocking structure.

[0120] Specifically, a movable extrusion piece 1123 and the first reset piece are provided between the outer shell 11211 and the inner shell 11212 of the brush. When the second fitting piece 12 is installed with the first fitting piece 11, the end portion of the second fitting piece 12 (the second connecting portion 122) abuts against the extrusion piece 1123, and then the locking portion 1124 is pushed up by the extrusion piece 1123, so that the locking portion 1124 is unlocked from the first positioning groove 1101. After unlocking, the second connecting portion 122 continues to push the brushing portion 112 to move along the suction portion 111. When the brushing portion 112 moves to the storage position on the suction portion 111, the locking hook of the second fitting piece 12 cooperates with the first positioning groove 1101 of the suction portion 111 to lock (an additional positioning structure can also be provided for locking the second fitting piece 12). At this time, the second fitting piece 12 and the first fitting piece 11 are installed in place. With this arrangement, the user does not need to move the brushing part 112 to the retracted position before assembling it with the second mating part 12. The user can directly assemble the first mating part 11 and the second mating part 12. Under the action of the second connecting part 122 and the extruding part 1123, the brushing part 112 can be automatically unlocked, so that the brushing part 112 automatically retracts during the mating process of the first mating part 11 and the second mating part 12, thereby improving the user experience.

[0121] In some embodiments, in combination with the above, the locking portion 1124 is rotatably connected to the brushing portion 112 and includes a pressing structure 11241 and a locking structure 11243, which are respectively provided on either side of the rotation axis. The locking structure 11243 is used to lock the brushing portion 112 and the suction portion 111, and the pressing structure 11241 is used to be pressed to unlock the brushing portion 112 and the suction portion 111. During use, the locking structure 11243 can lock the brushing portion 112 and the suction portion 111. Since the pressing structure 11241 and the locking structure 11243 are respectively provided on either side of the rotation axis, the action of pressing the pressing structure 11241 will lift the locking structure 11243. At this time, the locking structure 11243 will release the lock on the suction portion 111 and the brushing portion 112, thereby unlocking the suction portion 111 and the brushing portion 112.

[0122] A positioning groove can be provided on the outer surface of the suction portion 111. When the locking portion 1124 locks the brush portion 112 and the suction portion 111, the locking structure 11243 can be inserted into the positioning groove, thereby locking the brush portion 112 and the suction portion 111. In conjunction with the aforementioned embodiment, the brush portion 112 can have a working position and a storage position. Therefore, multiple positioning grooves can be provided on the suction portion 111 to facilitate locking the brush portion 112 in different positions. For example, the suction portion 111 can be provided with a first positioning groove 1101 and a second positioning groove 1102. When the brush portion 112 is in the working position, the locking portion 1124 locks into the first positioning groove 1101, thereby securing the brush portion 112 in the working position. When the brush portion 112 is in the storage position, the locking portion 1124 locks into the second positioning groove 1102, thereby securing the brush portion 112 in the storage position. Of course, a third positioning groove or the like may be further provided on the suction portion 111 so as to lock the brushing portion 112 between the storage position and the working position, or to lock the brushing portion 112 outside the storage position and the working position.

[0123] Optionally, when the brushing part 112 is in the storage position, the locking part 1124 on the brushing part 112 is locked with the second positioning groove 1102 of the suction part 111. After the first fitting part 11 and the second fitting part 12 are installed in place, the suction part 111 abuts against the matching surface of the inner wall of the second fitting part 12, and the locking part of the second fitting part 12 is locked with the first positioning groove 1101 of the suction part 111.

[0124] In combination with the aforementioned embodiment, the locking portion 1124 may include a pressing structure 11241, a wedge-shaped structure 11242, and a locking structure 11243, wherein the locking structure 11243 is located on one side of the rotation axis of the locking portion 1124, and the pressing structure 11241 and the wedge-shaped structure 11242 are located on the other side of the rotation axis of the locking portion 1124. When the extruding member 1123 presses the wedge-shaped structure 11242, it can achieve substantially the same effect as pressing the pressing structure 11241, thereby unlocking the locking portion 1124.

[0125] In addition, the first working component may also include a second reset member, which may be connected to the locking portion 1124 and may have an elastic force to drive the locking portion 1124 to move to the locked position, so that the locking portion 1124 can be reset after the external force driving the locking portion 1124 to unlock disappears, thereby achieving rapid locking of the brushing portion 112 and the suction portion 111.

[0126] As shown in Figures 1 to 15, the first matching member 11 includes a suction portion 111 and a brush portion 112 that can slide on the suction portion 111. The brush portion 112 has a working position and a storage position on the suction portion 111. When the brush portion 112 is in the storage position, the suction portion 111 can use the flat suction function, and when the brush portion 112 is in the working position, the brush portion 112 can use the brush function. Furthermore, a locking portion 1124 (such as a lock hook) is provided on the brush portion 112, and a first positioning groove that cooperates with the locking portion 1124 is provided on the suction portion 111. 1101 and a second positioning groove 1102, the brushing part 112 is also provided with a second reset part connected to the locking part 1124, the brushing part 112 has an inner shell 11212 and an outer shell 11211, the outer shell 11211 is provided with a mounting groove, and the locking part 1124 is rotatably passed through the mounting groove, the second reset part is located between the locking part 1124 and the inner shell 11212, the brushing part 112 also includes a cleaning structure 1122 (such as bristles), and the cleaning structure 1122 cannot be provided at the end of the inner shell 11212.

[0127] As previously mentioned, in the present disclosure, when installing and disassembling the second fitting 12, the brushing portion 112 can be installed on the suction portion 111, thereby avoiding problems such as the brushing portion 112 being lost due to removal. A positioning structure can also be provided in the present disclosure, and the positioning of the brushing portion 112 can be achieved through the positioning structure. In some embodiments, a positioning protrusion 1206 is provided on the outer peripheral surface of the suction portion 111, and the positioning protrusion 1206 is configured to limit the brushing portion 112 from falling out. The positioning protrusion 1206 can limit the brushing portion 112 from falling out, so that the brushing portion 112 can be stably located on the suction portion 111, thereby improving the stability of the first fitting 11.

[0128] As shown in FIG10 , the positioning protrusion 1206 has a first side surface and a second side surface that are opposite to each other. The first side surface is close to the first connecting portion 113 and is substantially perpendicular to the outer circumference of the brushing portion 112. In this way, the brushing portion 112 can be limited by the first side surface. The second side surface is away from the first connecting portion 113 and gradually increases in height relative to the outer circumference of the suction portion 111 in the direction approaching the first connecting portion 113. During the installation of the brushing portion 112, the brushing portion 112 can be sleeved from the end of the suction portion 111 away from the first connecting portion 113 and moved toward the first connecting portion 113. When the brushing portion 112 passes over the positioning protrusion 1206, the inclined second side surface will cause the suction portion 111 to elastically deform, thereby facilitating the brushing portion 112 to pass over. After the brushing portion 112 passes over the positioning protrusion 1206, the suction portion 111 recovers and uses the positioning protrusion 1206 to position the brushing portion 112.

[0129] Of course, the brushing part 112 can also be installed in other ways, for example, the brushing part 112 is sleeved onto the suction part 111 from the end opposite to the first side surface, or the brushing part 112 is arranged to be installed radially along the suction part 111, etc. The above description of the installation method of the brushing part 112 is only some embodiments of the present disclosure, and is not a limitation of the scope of protection of the present disclosure.

[0130] In some embodiments, a guide structure is provided between the brushing portion 112 and the suction portion 111, and the guide structure is configured to guide the brushing portion 112 to move along the suction portion 111. The guide structure can guide the movement of the brushing portion 112, so that the brushing portion 112 can move between the working position and the storage position, thereby improving the stability of the first matching member 11.

[0131] After the first fitting 11 and the second fitting 12 are docked and matched to form the straw attachment 10, there will be a gap between the outer wall of the suction part 111 and the inner wall of the second fitting 12. At the same time, an air hole is provided near the flat suction nozzle of the suction part 111. If the first fitting 11 and the second fitting 12 are not fully aligned and sealed, airflow will flow along the air holes and gaps into the area between the brushing part 112 and the inner wall of the second fitting 12, causing dust to remain in this area.

[0132] To ensure proper mating between the first and second mating components 11, 12, the suction portion 111 includes two symmetrically arranged first flat surfaces 1103, each provided with a guide structure. The interior of the second mating component 12 is provided with a surface and structure that mate with the first flat surfaces 1103 and the guide structure. The first and second mating components 11, 12 combine to form the complete vacuum cleaner assembly 100 connector. The first mating component 11 can be used as a separate flat suction component connected to the vacuum cleaner body 20.

[0133] In some embodiments, the outer circumferential surface of the suction portion 111 includes at least one first plane 1103, which can facilitate faster positioning of the first fitting 11 and the second fitting 12. The first plane 1103 cooperates with the inner circumferential surface of the second fitting 12 to circumferentially position the suction portion 111 and the second fitting 12. That is, when the second fitting 12 is assembled with the suction portion 111, the cooperation between the first plane 1103 and the inner circumferential surface of the second fitting 12 restricts the rotation of the second fitting 12 relative to the suction portion 111. Therefore, the cooperation between the first plane 1103 and the inner circumferential surface of the second fitting 12 facilitates stable cooperation between the suction portion 111 and the second fitting 12, thereby improving the stability of the cooperation between the suction portion 111 and the second fitting 12.

[0134] Specifically, the suction portion 111 is further provided with a first flat surface 1103 and a positioning protrusion 1206. The first flat surface 1103 facilitates the movement of the brushing portion 112 between the working position and the storage position. The first flat surface 1103 and the positioning protrusion 1206 cooperate to facilitate the movement and fixation of the brushing portion 112 between the working position and the storage position. In addition, the positioning protrusion 1206 is provided at a position of the suction portion 111 near the suction end. The inner wall of the brushing portion 112 is provided with a structure that cooperates with the positioning protrusion 1206. The positioning protrusion 1206 prevents the brushing portion 112 from separating from the suction portion 111 during the process of moving the brushing portion 112 from the storage position to the working position.

[0135] Optionally, a guide structure can be provided on the first plane 1103. After the first mating part 11 and the second mating part 12 are assembled, the guide structure can provide better positioning for the assembly of the first mating component and the second mating component, avoid shaking of the second mating part 12 after assembly, and improve the mating stability of the first mating component and the second mating component. In this way, when the pipe accessory 10 formed by the combination of the first mating part 11 and the second mating part 12 is working, the working surface can be better cleaned.

[0136] Among them, the stability of the assembly between the first fitting part 11 and the second fitting part 12 can be optimized by providing a structure that is compatible with the first fitting part 11 on the inner circumference of the second fitting part 12. For example, a corresponding flat position is provided on the inner circumference of the second fitting part 12. In this way, when the second fitting part 12 is assembled with the first fitting part 11, the inner circumference of the second fitting part 12 can transitionally match with the outer circumference of the suction part 111, and the first plane 1103 on the suction part 111 is compatible with the corresponding surface on the inner circumference of the second fitting part 12 to limit the rotation of the second fitting part 12 relative to the suction part 111, and can guide the second fitting part 12 to be installed on the suction part 111, so as to achieve stable matching between the second fitting part 12 and the suction part 111.

[0137] In addition, to facilitate the stability of the connection between the second mating component and the suction portion 111, the pipe attachment 10 includes a first assembly guide portion 1231 and / or a second assembly guide portion 1232. The first assembly guide portion 1231 and the second assembly guide portion 1232 are both used to provide guidance and positioning for the mating of the second mating component and the suction portion 111.

[0138] The first assembly guide 1231 is formed by the cooperation of the end surface 1202 and the step surface 1203. The end surface 1202 is provided on the suction portion 111, and the step surface 1203 is provided on the first mating component 11. The end surface 1202 may be an arcuate surface, and the step surface 1203 may be an arcuate surface that matches the end surface 1202. The cooperation of the arcuate step surface 1203 and the arcuate end surface 1202 enables stable assembly of the suction portion 111 and the second mating component 12, improving the assembly stability of the first mating component 11 and the second mating component 12 and facilitating use.

[0139] In addition, the second assembly guide 1232 is formed by the cooperation of the guide protrusion 1204 and the guide groove 1205. One of the guide protrusion 1204 and the guide groove 1205 is provided on the suction portion 111, and the other is provided on the second mating member 12. This can achieve stable assembly of the suction portion 111 and the second mating member 12, improve the assembly stability of the first mating member 11 and the second mating member 12, and facilitate use.

[0140] For example, a guide groove 1205 is provided on the inner circumferential surface of the second fitting 12, and a guide protrusion 1204 is provided on the first plane 1103, wherein a first guide rib and a second guide rib can be provided on the inner circumferential surface of the second fitting 12, and the first guide rib and the second guide rib are arranged at intervals along the circumference of the second fitting 12, so that a guide groove 1205 is formed between the first guide rib and the second guide rib, and a guide protrusion 1204 can be provided on the first plane 1103, and the guide protrusion 1204 is movably provided in the guide groove 1205 along the axial direction of the suction part 111, wherein the first guide rib can be set to extend along the axial direction; or the second guide rib can be set to extend along the axial direction; or the guide groove 1205 can be set to extend along the axial direction; or the guide protrusion 1204 can be set to extend along the axial direction.

[0141] In addition, in the aforementioned embodiment, the effective cooperation between the suction part 111 and the second matching part 12 can be achieved through the first plane 1103. Similarly, the first plane 1103 can also be set to position the suction part 111 and the brushing part 112. For example, the first plane 1103 can be matched with the inner circumferential surface of the brushing part 112 to circumferentially position the suction part 111 and the brushing part 112.

[0142] In conjunction with the aforementioned embodiment, to facilitate the stability of the connection between the brushing portion 112 and the suction portion 111, the pipe fitting 10 includes a third assembly guide. This guide is used to guide and position the brushing portion 112 and the suction portion 111. A guide groove 1205 is provided on the inner circumference of the second mating member 12, and a guide protrusion 1204 is provided on the first flat surface 1103. The third assembly guide can be formed by the groove and the guide protrusion on the inner circumference of the brushing portion 112.

[0143] For example, a groove is provided on the inner circumferential surface of the brushing portion 112, and a protrusion is provided on the first plane 1103, wherein a first rib and a second rib can be provided on the inner circumferential surface of the brushing portion 112, and the first rib and the second rib are arranged at intervals along the circumference of the brushing portion 112, so as to form a groove between the first rib and the second rib, and a protrusion can be provided on the first plane 1103, and the protrusion can be movably provided in the groove along the axial direction of the suction portion 111, wherein the first rib can be set to extend along the axial direction; or the second rib can be set to extend along the axial direction; or the groove can be set to extend along the axial direction; or the protrusion can be set to extend along the axial direction.

[0145] As shown in Figures 16 to 19, the present disclosure also provides a vacuum cleaner assembly 100, including a vacuum cleaner main body 20, a floor brush 30 and a pipe attachment 10 according to the aforementioned vacuum cleaner assembly 100. The vacuum cleaner assembly 100 has a first usage state and a second usage state. As shown in Figures 16 and 17, in the first usage state, the first fitting 11 and the second fitting 12 are matched with each other, the first fitting 11 is connected to the vacuum cleaner main body 20, and the second fitting 12 is connected to the floor brush 30; as shown in Figures 18 and 19, in the second usage state, the first fitting 11 and the second fitting 12 are separated from each other, and the first fitting 11 is connected to the vacuum cleaner main body 20.

[0146] In the vacuum cleaner assembly 100 disclosed in the present invention, the first fitting 11 can be used as a part of the connecting pipe accessory 10 when not in use, and can be assembled with the second fitting 12 for use, without affecting the installation and use of the second fitting 12. It also avoids the problem of needing to remove the first fitting 11 or the brushing part 112 and place it elsewhere when installing the second fitting 12. The connecting pipe accessory 10 is easy to use and avoids the loss or jamming of parts. The first fitting 11 can adjust the working mode by moving the brushing part 112 when in use; the brushing part 112 can be displayed through the exposed brushing part 112, and the brushing part 112 can be easily separated from the second fitting 12.

[0147] The present disclosure also provides a vacuum cleaner assembly 100, comprising a vacuum cleaner body 20, a floor brush 30, and the aforementioned pipe attachment 10 that can be directly or indirectly connected to the vacuum cleaner body 20 and the floor brush 30. The pipe attachment 10 includes a first fitting 11 and a second fitting 12. The first fitting includes a suction portion 111 and a brushing portion 112. The brushing portion 112 is movable relative to the suction portion 111. The vacuum cleaner assembly includes a first connection state and a second connection state. In the first connection state, the first fitting 11 and the second fitting 12 are mated with each other. The first fitting 11 is directly or indirectly connected to the vacuum cleaner body, the second fitting 12 is directly or indirectly connected to the floor brush, and the brushing portion is at least partially located outside the second fitting 12. In the second connection state, the first fitting 11 and the second fitting 12 are separated from each other, and the first fitting 11 is directly or indirectly connected to the vacuum cleaner body.

[0148] In some embodiments, the brushing portion 112 includes a main structure 1121 and a cleaning structure 1122 connected to the main structure 1121. The brushing portion 112 has a first state in which the cleaning structure 1122 is not working and a second state in which the cleaning structure is working. In the first connection state, the brushing portion 112 is in the first state. In the second connection state, the brushing portion 112 is in the second state or can change from the first state to the second state.

[0149] 20 and 21 , the pipe attachment 10 of the vacuum cleaner assembly 100 according to an embodiment of the present disclosure includes a first mating member 11 and a second mating member 12. The second mating member 12 is connected to the first mating member 11. The main body of the first mating member 11 includes at least one first flat surface 1103. The first flat surface 1103 cooperates with the inner circumference of the second mating member 12 to circumferentially position the first and second mating members 11, 12 during installation. The first flat surface 1103 facilitates faster positioning of the first and second mating members 11, 12. Specifically, when the second mating member 12 is assembled with the suction portion 111, the cooperation between the first flat surface 1103 and the inner circumference of the second mating member 12 restricts rotation of the second mating member 12 relative to the suction portion 111. Therefore, the cooperation between the first flat surface 1103 and the inner circumference of the second mating member 12 facilitates stable mating between the suction portion 111 and the second mating member 12, thereby improving the stability of the mating between the suction portion 111 and the second mating member 12.

[0150] According to the pipe attachment 10 of the vacuum cleaner assembly 100 of the embodiment of the present disclosure, the first fitting 11 has a first plane 1103, and the second fitting 12 has a structure adapted to the first plane 1103, which can realize circumferential positioning between the first fitting 11 and the second fitting 12 and limit the rotation of the first fitting 11 relative to the second fitting 12.

[0151] The second mating piece 12 can be configured to be connected to the first mating piece 11 along the axial direction of the first mating piece 11. Therefore, the second mating piece 12 can be configured to be movable along the axial direction of the first mating piece 11 (refer to the vertical direction in Figure 20) while being relatively stationary in the circumferential direction. The first plane 1103 enables rapid assembly of the first mating piece 11 and the second mating piece 12. In addition, the first mating piece 11 can be provided with multiple first planes 1103, and the multiple first planes 1103 can be arranged along the circumference of the first mating piece 11. For example, the first mating piece 11 can be provided with multiple first planes 1103 connected in sequence along the circumference to form an annular surface; or the first mating piece 11 can be provided with multiple first planes 1103 and multiple arcuate surfaces, and the multiple first planes 1103 and multiple arcuate surfaces are arranged along the circumference to form an annular surface, etc. In some embodiments of the present disclosure, the first mating piece 11 is provided with two first planes 1103 stacked on each other.

[0152] Among them, the stability of the assembly between the first fitting part 11 and the second fitting part 12 can be optimized by providing a structure that is compatible with the first fitting part 11 on the inner circumference of the second fitting part 12. For example, a corresponding flat position is provided on the inner circumference of the second fitting part 12. In this way, when the second fitting part 12 is assembled with the first fitting part 11, the inner circumference of the second fitting part 12 can cooperate with the flat position of the outer circumference of the suction part 111 to limit the rotation of the second fitting part 12 relative to the suction part 111, and can guide the second fitting part 12 to be installed on the suction part 111, so as to achieve stable cooperation between the second fitting part 12 and the suction part 111.

[0153] In addition, to facilitate the stability of the connection between the second mating member 12 and the suction portion 111, the pipe attachment 10 includes a first assembly guide 1231 and / or a second assembly guide 1232. The first assembly guide 1231 and the second assembly guide 1232 are both used to guide and position the second mating member 12 and the suction portion 111.

[0154] As shown in Figure 21, in some embodiments of the present disclosure, a first guide structure is provided on the first plane 1103, and a second guide structure is provided on the inner circumferential surface of the second mating member 12. The first guide structure and the second guide structure cooperate to circumferentially position the first mating member 11 and the second mating member 12. The cooperation of the first guide structure and the second guide structure enables axial movement of the second mating member 12 and the first mating member 11, facilitating stable and rapid connection of the second mating member 12 and the first mating member 11. Furthermore, the cooperation of the first guide structure and the second guide structure also enables relative axial positioning of the first mating member 11 and the second mating member 12, thereby limiting circumferential rotation of the second mating member 12 relative to the first mating member 11, thereby improving the connection stability of the first mating member 11 and the second mating member 12.

[0155] 21 , 31 , and 33 , one of the first and second guide structures may include a guide protrusion 1204, and the other may include a guide groove 1205. When the first and second guide structures are assembled and mated, the guide protrusion 1204 is movably disposed within the guide groove 1205. For example, the first guide structure may include the guide protrusion 1204, and the second guide structure may include the guide groove 1205. At least one of the guide groove 1205 and the guide protrusion 1204 may extend along the axis of the pipe attachment 10. Thus, during assembly of the second mating component with the first mating component, the guide protrusion 1204 is inserted into the guide groove 1205, and the guide protrusion 1204 can move relative to the guide groove 1205 along the axis of the pipe attachment 10. This allows for stable and rapid mating of the first and second mating components 11, 12. Furthermore, the rotation of the first mating component 11 relative to the second mating component 12 can be restricted, thereby improving the connection stability between the first and second mating components 11, 12.

[0156] As shown in Figure 33, a first guide rib 1241 and a second guide rib 1242 can be provided on the inner circumferential surface of the second fitting 12, and the first guide rib 1241 and the second guide rib 1242 are arranged at intervals along the circumference of the second fitting 12, so that a guide groove 1205 is formed between the first guide rib 1241 and the second guide rib 1242. A guide protrusion 1204 can be provided on the first plane 1103, and the guide protrusion 1204 can be movably provided in the guide groove 1205 along the axial direction of the suction portion 111, wherein the first guide rib 1241 can be set to extend along the axial direction; or the second guide rib 1242 can be set to extend along the axial direction; or the guide groove 1205 can be set to extend along the axial direction; or the guide protrusion 1204 can be set to extend along the axial direction.

[0157] Of course, it can also be configured that the first guide structure includes the guide groove 1205 and the second guide structure includes the guide protrusion 1204 .

[0158] As shown in Figures 21 to 24, in some embodiments of the present disclosure, the inner circumferential surface of the second fitting 12 includes a second plane 1207. The second plane 1207 and the first plane 1103 are relatively movable along the axial direction of the pipe fitting 10 and are relatively limited along the circumferential direction of the pipe fitting 10. Through the cooperation of the first plane 1103 and the second plane 1207, the first fitting 11 and the second fitting 12 can be matched through the flat structure, thereby ensuring the assembly stability of the first fitting 11 and the second fitting 12, and facilitating the assembly and separation of the various parts of the pipe fitting (10).

[0159] In addition, the outer circumferential surface of the first mating component 11 further includes a first mating surface 1104, which is connected to the first plane 1103 along the circumferential direction of the first mating component 11. The inner circumferential surface of the second mating component 12 further includes a second mating surface 1208, which is connected to the second plane 1207 along the circumferential direction of the first mating component 11. The second mating surface 1208 is opposite to the first mating surface 1104, and the second plane 1207 is opposite to the first mating surface 1104. This can further improve the mating stability between the first mating component 11 and the second mating component 12.

[0160] The outer peripheral surface of the first matching member 11 includes one or more first planes 1103. For example, one first plane 1103 may be provided on the first matching member 11, or two first planes 1103 may be provided on the first matching member 11 in a symmetrical arrangement.

[0161] In addition, the first mating surface 1104 is an arcuate surface or an arcuate surface centered on the axis of the first mating piece 11 , which can facilitate the mating of the first mating piece 11 and the second mating piece 12 and facilitate surface cleaning using the first mating piece 11 .

[0162] In addition, as shown in Figures 25 and 26 , the first and second mating members 11 and 12 may further have an end face 1202 and a stepped surface 1203 that cooperate with each other. In conjunction with Figures 26 and 28 , in some embodiments of the present disclosure, the second mating member 12 includes a rod 121 and a second connecting portion 122. The interior of the second connecting portion 122 includes a stepped surface 1203. After the second mating member 12 is connected to the first mating member 11, at least a portion of the first mating member 11 can be positioned within the second connecting portion 122, with the end face 1202 of the first mating member 11 facing the stepped surface 1203. The cooperation between the end face 1202 and the stepped surface 1203 allows for positioning of the first and second mating members 11 and 12, achieving stable cooperation between the first and second mating members 11 and 12, and improving the connection stability of the first and second mating members 11 and 12.

[0163] At least a portion of the end surface 1202 can be configured as a curved surface, and at least a portion of the step surface 1203 can be configured as a curved surface that matches the curved surface. The end surface 1202 can be a curved surface, and the step surface 1203 can be configured as a curved surface that matches the end surface 1202. The coordination of the curved step surface 1203 and the curved end surface 1202 enables stable assembly of the suction portion 111 and the second mating component 12, improving assembly stability of the first mating component 11 and the second mating component 12 and facilitating use.

[0164] In addition, as shown in Figures 25 to 28, in other embodiments of the present disclosure, the first fitting part 11 may include a suction part 111 and a brushing part 112, and the brushing part 112 may be movably connected to the suction part 111 and may be moved along the axial direction of the suction part 111. The second fitting part 12 may be connected to the suction part 111, and when the second fitting part 12 is installed on the suction part 111, the suction part 111 and the brushing part 112 are opposite to each other along the axial direction of the suction part 111, wherein the end of the brushing part 112 close to the second fitting part 12 may be a slope or an arc surface, and the end of the second fitting part 12 close to the brushing part 112 may be set as an arc surface or a slope, and the shape of the surface opposite to the brushing part 112 of the second fitting part 12 is adapted.

[0165] In combination with the above, in combination with Figures 21 and 26, the connecting pipe accessory 10 includes a first assembly guide portion 1231 and a second assembly guide portion 1232, wherein the first assembly guide portion 1231 can be set as the cooperation of the aforementioned end face 1202 and the step surface 1203, that is, the first assembly guide portion 1231 is the cooperation of the arc-shaped end face 1202 and the arc-shaped step surface 1203, the end face 1202 is provided on the first mating piece 11, and the step surface 1203 is provided on the second mating piece 12.

[0166] The second assembly guide portion 1232 can be set as the cooperation of the aforementioned guide protrusion 1204 and the guide groove 1205, that is, the second assembly guide portion 1232 is the cooperation of the guide protrusion 1204 and the guide groove 1205, one of the guide protrusion 1204 and the guide groove 1205 is set on the first mating part 11, and the other is set on the second mating part 12.

[0167] In addition, when the first fitting member 11 and the second fitting member 12 are assembled and matched, the first assembly guide portion 1231 can be located upstream of the second assembly guide portion 1232. In this way, the matching stability of the first fitting member 11 and the second fitting member 12 can be improved by multiple positioning.

[0168] As shown in Figures 20 and 21, in some embodiments of the present disclosure, the first fitting member 11 includes a suction portion 111, the outer circumferential surface of the suction portion 111 includes a first flat surface 1103, and the second fitting member 12 includes a rod 121 and a second connecting portion 122 for releasably connecting the second fitting member 12 to the first fitting member 11. Thus, the first flat surface 1103 on the suction portion 111 allows for a stable fit between the second fitting member 12 and the suction portion 111, facilitating connection of the second fitting member 12 to the suction portion 111 and allowing airflow to flow through the second fitting member 12 and the first fitting member 11 to the negative pressure device, thereby achieving garbage cleaning and dust removal.

[0169] As shown in Figures 28 to 37, in some embodiments of the present disclosure, the first mating member 11 includes a suction portion 111 and a brushing portion 112. The brushing portion 112 is movable on the suction portion 111. The outer circumferential surface of the suction portion 111 includes a first flat surface 1103. The first flat surface 1103 cooperates with the inner circumferential surface of the brushing portion 112 to circumferentially position the suction portion 111 and the brushing portion 112. Thus, the first flat surface 1103 on the suction portion 111 can achieve stable mating between the brushing portion 112 and the suction portion 111, thereby improving the stability of the mating between the brushing portion 112 and the suction portion 111.

[0170] In combination with the above, a guide protrusion 1204 can be provided on the first plane 1103 of the suction portion 111, and a positioning groove 1209 can be provided on the inner circumferential surface of the brushing portion 112, and the guide protrusion 1204 can be slidably inserted into the positioning groove 1209 along the axial direction, and at least one of the positioning groove 1209 and the guide protrusion 1204 extends along the axial direction.

[0171] In combination with the above-mentioned embodiment, the first matching piece 11 includes a suction part 111, a brushing part 112 and a first connecting part 113, and the second matching piece 12 may include a rod 121 and a second connecting part 122. At least one first plane 1103 is provided on the outer surface of the suction part 111. The brushing part 112 is movably connected to the suction part 111, and the second connecting part 122 is detachably connected to the suction part 111. Through the first plane 1103 on the suction part 111, the brushing part 112 and the second matching piece 12 can be stably installed, which facilitates the use of the suction pipe accessory 10.

[0172] Among them, the suction part 111 can be used to clean gaps, corners and narrow areas. The brushing part 112 can be used to clean countertops, surfaces and other areas to avoid scratching the countertops while cleaning. The brushing part 112 can be moved on the suction part 111. The first fitting part 11 also includes a first connecting part 113, and the first connecting part 113 can be connected to the vacuum cleaner body 20. The first fitting part 11 can be used as a separate accessory, which is connected to the vacuum cleaner body 20 when in use. It can be sold together with the vacuum cleaner assembly 100 or sold separately. In addition, the accessory head can be directly connected to the vacuum cleaner body 20; or an intermediate piece can be provided between the accessory head and the vacuum cleaner body 20 to indirectly connect the accessory head and the vacuum cleaner body 20 through the intermediate piece.

[0173] The first fitting member 11 may also be connected to the cleaner body 20 as a part of the cleaner body 20. The second fitting member 12 may include a rod 121 and a second connecting portion 122. The second connecting portion 122 is used to releasably connect the second fitting member 12 to the first fitting member 11. The second fitting member 12 may serve as a portion connecting the cleaner body 20 and the floor brush 30 of the cleaner assembly 100, generally as a separate accessory. One end of the second fitting member 12 may have a connector portion (i.e., the second connecting portion 122) for connecting to the first fitting member 11, and the other end may have a connector portion for connecting to the floor brush 30.

[0174] When cleaning the floor, the user can connect the vacuum cleaner body 20 to the floor brush 30 via the second fitting 12. When cleaning a tabletop, the user generally uses the brushing function of the sweeping portion 112 of the first fitting 11. When cleaning the gap between a seat and a backrest or other gaps, the user generally uses the suction portion 111 of the first fitting 11. Therefore, in the pipe attachment 10 of the present disclosure, the first fitting 11 can be used separately as a flat suction member or a brush attachment. The first fitting 11 and the second fitting 12 can be combined to form a complete pipe, which can be connected to the floor brush 30 to clean the floor or walls.

[0175] When the second fitting 12 is connected to the first fitting 11, at least a portion of the suction portion 111 is located inside the second fitting 12, and at least a portion of the brushing portion 112 is located outside the second fitting 12. When the operating mode is switched from the working environment of the first fitting 11 to the working environment of the second fitting 12, there is no need to disassemble the first fitting 11 or remove the brushing portion 112 from the suction portion 111. Instead, the second fitting 12 and the first fitting 11 are assembled together to form the pipe attachment 10, avoiding the problem of having nowhere to place or being easily lost after the individual components are removed.

[0176] In the present disclosure, at least a portion of the suction part 111 is arranged inside the second fitting 12, which can facilitate the airflow to circulate between the first fitting 11 and the second fitting 12, and facilitate the use of the pipe attachment 10; at least a portion of the brushing part 112 is arranged outside the second fitting 12, which can facilitate the user to intuitively view the brushing part 112 and remind the user of the position of the brushing part 112. When it is necessary to switch to using the brushing part 112 for cleaning, there is no need to look for it elsewhere.

[0177] Specifically, the second fitting 12 includes a suction inlet connected to the floor brush 30, a second connecting portion 122 connected to the first fitting 11, and the first fitting 11 and / or the second fitting 12 are provided with a locking hook for fixing the first fitting 11 and the second fitting 12 together, and the second connecting portion 122 has a bent step; after the first fitting 11 and the second fitting 12 are engaged, the protruding portion of the step extends into the end of the brushing portion 112; when the first fitting 11 and the second fitting 12 are assembled together, the outer surface of the brushing portion 112 and the outer wall of the second fitting 12 jointly constitute the outer surface of the pipe attachment 10, and the inner wall surface of the suction portion 111 and the inner wall surface of the rod 121 jointly form the suction channel of the pipe assembly.

[0178] In addition, a positioning groove can be provided on the suction portion 111, and a locking hook can be provided on the second mating piece 12. When the second mating piece 12 is connected to the first mating piece 11, the locking hook can be inserted into the positioning groove to achieve stable mating between the second mating piece 12 and the first mating piece 11. In addition, the second mating piece 12 and the first mating piece 11 can be unlocked by disengaging the locking hook from the positioning groove. The positioning groove can be the second positioning groove 1102 in the following embodiment, or other grooves.

[0179] The second matching piece 12 and the brushing portion 112 in the present disclosure may also be configured in a sleeve-connected form. For example, at least a portion of the brushing portion 112 may be configured to surround the second matching piece 12 .

[0180] As shown in Figures 36 and 37, in some embodiments of the present disclosure, the brush sweeping portion 112 has a working position (as shown in Figure 36) and a storage position (as shown in Figure 37). In the working position, the brush sweeping portion 112 is deployed relative to the suction portion 111 and locked with the suction portion 111. In the storage position, the brush sweeping portion 112 is retracted relative to the suction portion 111. When the brush sweeping portion 112 is in the working position, the cleaning structure 1122 can be configured to extend beyond the end of the suction portion 111 to facilitate cleaning the work surface. Specifically, in combination with the above, the cleaning structure 1122 of the brush sweeping portion 112 extends beyond the end of the suction portion 111. When the suction part 111 is needed to perform suction, or when the second fitting 12 needs to be connected to the first fitting 11, the brushing part 112 can be moved to the storage position. In this way, the brushing part 112 can be prevented from affecting the connection between the second fitting 12 and the first fitting 11. At the same time, the end of the suction part 111 can be used for suction, and the suction part 111 can be used to clean gaps and narrow corners; when the brushing part 112 is needed, the brushing part 112 can be moved to the working position, and the cleaning structure 1122 (such as bristles) of the brushing part 112 can extend out of the end of the suction part 111, so that the cleaning structure 1122 can be used to clean the working surface, which can be used to clean countertops, surfaces and other areas, avoiding scratching the countertop while cleaning. At the same time, after the brushing part 112 brushes, suction can be performed through the suction part 111 to remove dust.

[0181] The brushing portion 112 can be sleeved around the outer periphery of the suction portion 111. This allows the brushing portion 112 to be configured to move axially along the suction portion 111 to adjust its position relative to the suction portion 111. The brushing portion 112 can have a working position and a stowed position. When the brushing portion 112 is in the working position, the cleaning structure 1122 thereon can extend out of the suction portion 111 to facilitate brushing the work surface. When the brushing portion 112 is in the stowed position, the suction portion 111 extends outward from the brushing portion 112, enabling connection to the second mating member 12 or to suction dust from the work surface. Furthermore, when the second mating member 12 is connected to the first mating member 11, the second connecting portion 122 sleeves onto the suction portion 111.

[0182] A first positioning groove 1101 and / or a second positioning groove 1102 can be provided on the suction part 111, and a locking part can be provided on the brushing part 112. The brushing part 112 is positioned in the working position by cooperation between the locking part and the second positioning groove 1102, and the cleaning structure 1122 extends out of one end of the suction part 111; the brushing part 112 can be positioned in the storage position by cooperation between the locking part and the first positioning groove 1101, and the brushing part 112 is retracted at the other end of the suction part 111.

[0183] As shown in Figure 34, the brushing unit 112 includes a main structure 1121 and a cleaning structure 1122 connected to the main structure 1121. The cleaning structure 1122 can be used to clean the work surface. When the second mating member 12 is connected to the first mating member 11, at least a portion of the main structure 1121 is located outside the second mating member 12, and at least a portion of the cleaning structure 1122 is located inside the second mating member 12. This prevents damage to the cleaning structure 1122 during installation of the second mating member 12 to the first mating member 11, and the cleaning structure 1122 can be protected by the second mating member 12, thereby improving the stability of the brushing unit 112, maintaining the stability of the cleaning structure 1122, and facilitating its use.

[0184] The brush sweeping portion 112 may have a working position and a storage position. The brush sweeping portion 112 may be stored on the suction portion 111 in the storage position and unfolded relative to the suction portion 111 in the working position. When the brush sweeping portion 112 is in the working position, the cleaning structure 1122 may be configured to extend out of the end of the suction portion 111 to facilitate cleaning the working surface. The cleaning structure 1122 may include bristles or flexible brush strips, etc. In addition, when the brush sweeping portion 112 is in the storage position, the brush sweeping portion 112 is stored on the suction portion 111, and the end of the suction portion 111 may be extended out of the brush sweeping portion 112, and the end of the suction portion 111 may be further extended out of the cleaning structure 1122 of the brush sweeping portion 112.

[0185] To facilitate installation of the second mating member 12, the brushing portion 112 can be moved to the storage position when the second mating member 12 is mounted on the first mating member 11. For example, the brushing portion 112 can be moved to the storage position before the second mating member 12 is connected to the first mating member 11. For another example, the brushing portion 112 can be unlocked by the second mating member 12 when the second mating member 12 is connected to the first mating member 11. For another example, the brushing portion 112 can be driven to move to the storage position by the second mating member 12 when the second mating member 12 is connected to the first mating member 11.

[0186] In some embodiments of the present disclosure, when the second mating member 12 is connected to the first mating member 11, if the brushing portion 112 is in the working position, the second mating member 12 can drive the brushing portion 112 and the suction portion 111 to unlock and move the brushing portion 112 to the storage position. In this way, when the second mating member 12 is connected to the first mating member 11, there is no need to move the brushing portion 112 to the storage position in advance. Instead, the second mating member 12 can be directly connected to the first mating member 11, which improves the assembly efficiency of the second mating member 12 and the first mating member 11.

[0187] The brushing part 112 and the suction part 111 can be locked by various methods such as interference fit, snap fit, and locking with a locking piece. Correspondingly, the brushing part 112 and the suction part 111 can also be unlocked by various methods. For example, if the brushing part 112 and the suction part 111 are locked by interference fit, the brushing part 112 can be unlocked by applying an external force to the brushing part 112; when the brushing part 112 and the suction part 111 are snap fit, the unlocking can be achieved by releasing the snap fit; when locking with a locking piece, the unlocking can be achieved by pressing, electric control, etc. The following disclosure provides a solution for locking and unlocking the brushing part 112 and the suction part 111 using a locking piece, but this does not limit the scope of protection of the present disclosure.
