[0038] The present application provides a cleaning device and its application accessory pipe group and accessory brush, which are described in detail below. It should be noted that the description order of the following embodiments is not limited as the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0039] Please refer toFigure 1 Figure 1 is a structural schematic diagram of an embodiment of the cleaning device.

[0040] In an embodiment, the cleaning device 10 can be a portable cleaning apparatus, such as a fabric cleaning machine or the like. The cleaning device 10 comprises a main machine 11, an accessory pipe set 20, and an accessory brush 30. The main machine 11 is connected to the accessory brush 30 through the accessory pipe set 20. A user can carry the cleaning device 10 and use the accessory brush 30 to clean a fabric surface, such as a sofa, a carpet, a blanket, or the like.

[0041] Please refer to Figures 2 to 4 Figure 2 is a structural schematic diagram of an embodiment of the cleaning device. Figure 1 is a structural schematic diagram of an embodiment of the cleaning device. Figure 3 is a structural schematic diagram of an embodiment of the cleaning device. Figure 2 is a sectional structural schematic diagram of the cleaning device along the direction A-A. Figure 4 is a structural schematic diagram of an embodiment of the cleaning device in the area M. Figure 3

[0042] In an embodiment, the accessory pipe set 20 has a first pipe joint 20a and a second pipe joint 20b. The first pipe joint 20a is connected to the main machine 11, and the second pipe joint 20b is connected to the accessory brush 30. Specifically, the accessory brush 30 is inserted into the second pipe joint 20b, and the accessory brush 30 can rotate relative to the second pipe joint 20b. In this way, during the cleaning process, the user can rotate the accessory brush 30 so that the accessory brush 30 can adapt to different cleaning scenarios. For example, no matter whether the surface of the object to be cleaned is a horizontal surface or a vertical surface, the accessory brush 30 can be rotated to face the surface to clean the surface. That is, the embodiment can improve the flexibility of the accessory brush 30 in cleaning work, thereby facilitating the improvement of the user's experience. In this embodiment, the accessory brush 30 is allowed to rotate relative to the second pipe joint 20b by an angle of 360°, thereby maximizing the flexibility of the accessory brush 30.

[0043] Moreover, in this embodiment, after the accessory brush 30 is inserted into the second pipe joint 20b, a flow passage 13 is formed between the second pipe joint 20b and the accessory brush 30. The accessory pipe set 20 is in fluid communication with the accessory brush 30 through the flow passage 13. In this way, on the basis of allowing the accessory brush 30 to rotate, the accessory pipe set 20 can provide cleaning liquid to the accessory brush 30 through the flow passage 13 to assist the accessory brush 30 in cleaning work.

[0044] ​​​Further, the cleaning device 10 further comprises a first sealing member 12. After the accessory brush 30 is inserted into the second pipe joint 20b, a flow channel 13 is formed between the second pipe joint 20b and the accessory brush 30 by the first sealing member 12, and the first sealing member 12 can seal the flow channel 13 during the rotation of the accessory brush 30 relative to the second pipe joint 20b. In this way, the accessory pipe group 20 of the embodiment can provide the cleaning liquid to the accessory brush 30 through the sealed flow channel 13, and the first sealing member 12 can ensure that the flow channel 13 has a good sealing effect, so as to avoid the leakage of the cleaning liquid in the flow channel 13. Of course, in other embodiments of the present application, the accessory brush 30 and the second pipe joint 20b can be tightly attached to each other to achieve the effect of sealing the flow channel 13, which is not limited herein.

[0045] It should be noted that the second pipe joint 20b of the accessory pipe group 20 and the accessory brush 30 of the embodiment are in contact with the first sealing member 12. Moreover, during the rotation of the accessory brush 30 relative to the second pipe joint 20b, the second pipe joint 20b and / or the accessory brush 30 can slide relative to the first sealing member 12. In other words, the second pipe joint 20b and / or the accessory brush 30 of the embodiment can slide relative to the first sealing member 12 to allow the rotation of the accessory brush 30 relative to the second pipe joint 20b, while the first sealing member 12 can still seal the flow channel 13 during the rotation of the accessory brush 30, so as to avoid the leakage of the cleaning liquid in the flow channel 13.

[0046] Moreover, the present application is described by taking the example that the accessory pipe group 20 provides the cleaning liquid to the accessory brush 30 through the flow channel 13. Of course, in other embodiments of the present application, the flow channel 13 can be applied to recover the dirt, i.e., the dirt absorbed by the accessory brush 30 during the cleaning process can be recovered to the main machine 11 through the flow channel 13, which is not limited herein.

[0047] Optionally, the cleaning liquid can be water, or a cleaning agent, or a mixture of water and a cleaning agent, which is not limited herein.

[0048] Please refer to Figure 5 , Figure 5 is Figure 2 the sectional structure schematic diagram of the cleaning device B-B direction.

[0049] In an embodiment, the accessory brush 30 comprises a brush body 31 and a brush joint 32. The brush body 31 is used for cleaning work. The brush joint 32 is connected to the brush body 31, and the brush joint 32 is used for being inserted into the second pipe joint 20b of the accessory pipe group 20. Specifically, the brush joint 32 has an insertion cavity 321 inside, and the second pipe joint 20b is specifically inserted into the insertion cavity 321.

[0050] The first sealing element 12 is annularly disposed around the outer periphery of the second pipe connector 20b. After the second pipe connector 20b is inserted into the insertion cavity 321, the outer wall of the second pipe connector 20b, the cavity wall of the insertion cavity 321, and the first sealing element 12 cooperate to form a flow channel 13 annularly disposed around the outer periphery of the second pipe connector 20b. Further, the brush connector 32 has a flow connector 33 on its exterior, and the flow channel 13 is in fluid communication with the brush body 31 through the flow connector 33. The flow direction of the cleaning fluid is as follows: Figure 5 As indicated by the dashed arrow.

[0051] In this way, since the flow channel 13 is a sealed annular cavity, even if the accessory brush 30 is in a rotating state, the annular flow channel 13 is always in fluid communication with the flow connector 33. Therefore, the cleaning fluid delivered by the accessory tube assembly 20 can be delivered to the brush body 31 through the flow channel 13. That is, this embodiment not only allows the accessory brush 30 to rotate, but also provides cleaning fluid to the accessory brush 30 through the accessory tube assembly 20 to assist the accessory brush 30 in cleaning.

[0052] Furthermore, the accessory brush 30 also includes a connector fastener 35. The connector fastener 35 cooperates with the brush connector 32 to confine the second pipe connector 20b within the insertion cavity 321, while allowing relative rotation of the second pipe connector 20b within the insertion cavity 321. For example, Figure 4 An exemplary illustration shows that the connector fastener 35 has a snap-fit ​​351, and the brush connector 32 has a corresponding slot 352 for the snap-fit ​​351. After the second pipe connector 20b is inserted into the insertion cavity 321, the snap-fit ​​351 and the slot 352 engage, allowing the connector fastener 35 and the brush connector 32 to confine the second pipe connector 20b within the insertion cavity 321. Furthermore, several sets of snap-fit ​​351 and slots 352 are provided circumferentially on the second pipe connector 20b. Of course, the connection method between the connector fastener 35 and the brush connector 32 is not limited to the snap-fit ​​351 and slot 352 connection method; for example, the connector fastener 35 and the brush connector 32 can also be connected by magnetic attraction or other connection methods, which are not limited here.

[0053] In one embodiment, the cleaning device 10 has a predetermined direction (e.g., Figure 4 As indicated by the middle arrow X (the same applies below), the second pipe joint 20b of the accessory pipe assembly 20 and the accessory brush 30 are inserted into each other along a predetermined direction. The number of first seals 12 is at least two. Each first seal 12 is arranged around the outer periphery of the second pipe joint 20b, and the first seals 12 are distributed sequentially at intervals along a predetermined direction, so that a flow channel 13 is formed between two adjacent first seals 12.

[0054] For example, the first seal 12 can be an O-ring or the like, and the first seal 12 is tightly sleeved on the outer periphery of the second pipe joint 20b, and the second pipe joint 20b clamps the first seal 12 in cooperation with the accessory brush 30 to form a seal. The outer periphery of the second pipe joint 20b can be provided with a groove structure, and the first seal 12 is embedded in the groove structure to limit the position of the first seal 12 in a predetermined direction. Figure 4 Exemplarily, the number of the first seal 12 is two, and the two first seals 12 are distributed in a predetermined direction to form a flow passage 13 between the two first seals 12. Of course, in other embodiments of the present application, a larger number of first seals 12 can be provided to form a plurality of flow passages 13, which can be in fluid communication with the brush body 31 through one or more flow joints 33.

[0055] In an embodiment, the accessory pipe group 20 has a first recovery channel 21 inside, and the dirt absorbed by the accessory brush 30 is recovered to the main machine 11 through the first recovery channel 21. Further, the accessory pipe group 20 further includes a recovery pipe 24. The two ends of the recovery pipe 24 are connected with the first pipe joint 20a and the second pipe joint 20b respectively, and the inside of the recovery pipe 24 is provided with at least part of the first recovery channel 21. Specifically, the cavities inside the recovery pipe 24, the first pipe joint 20a and the second pipe joint 20b are in fluid communication with each other to constitute the first recovery channel 21. Optionally, the recovery pipe 24 can be a threaded pipe or the like, and the end of the recovery pipe 24 can be fixed to a bracket by glue, and the bracket is fixed to the second pipe joint 20b by a fastener such as a screw, which is not limited here.

[0056] The accessory pipe group 20 further includes an isolation assembly 22. The isolation assembly 22 is arranged in the first recovery channel 21. The inside of the isolation assembly 22 has an isolation channel 221, which is isolated from the first recovery channel 21, that is, the dirt recovered in the first recovery channel 21 cannot enter the isolation channel 221.

[0057] The accessory pipe group 20 further includes a liquid outlet pipe 23. The liquid outlet pipe 23 is in fluid communication with the accessory brush 30 through the flow passage 13, and the liquid outlet pipe 23 is used to provide cleaning liquid to the accessory brush 30. Further, the main machine 11 has a liquid storage tank for storing cleaning liquid. One end of the liquid outlet pipe 23 is in fluid communication with the accessory brush 30 through the flow passage 13, and the other end is connected with the main machine 11, and the liquid storage tank provides cleaning liquid to the accessory brush 30 through the liquid outlet pipe 23.

[0058] It should be noted that, in this embodiment, the liquid outlet pipe 23 delivers clean cleaning liquid, and therefore the liquid outlet pipe 23 is arranged in the isolation channel 221, so that the liquid outlet pipe 23 is isolated from the first recovery channel 21, and thus the dirty collected by the first recovery channel 21 cannot reach the liquid outlet pipe 23, thereby avoiding the clean liquid in the liquid outlet pipe 23 from being contaminated by the dirty collected by the first recovery channel 21.

[0059] Further, the isolation channel 221 is divided into a first sub-channel 2211 and a second sub-channel 2212 which are in communication with each other. The isolation assembly 22 further comprises an isolation end cover 222. The isolation end cover 222 is arranged in the second pipe joint 20b, and the isolation end cover 222 cooperates with the second pipe joint 20b to form the first sub-channel 2211. The isolation assembly 22 further comprises an isolation pipe 223. The isolation pipe 223 is connected to the isolation end cover 222, and the interior of the isolation pipe 223 has the second sub-channel 2212. The liquid outlet pipe 23 is arranged in the second sub-channel 2212, and the liquid outlet pipe 23 extends into the first sub-channel 2211 to be in fluid communication with the overflow channel 13.

[0060] For example, the second pipe joint 20b has a cavity in the interior thereof, and the isolation end cover 222 is located in the cavity in the interior of the second pipe joint 20b. The isolation end cover 222 cooperates with the inner wall of the second pipe joint 20b to form the first sub-channel 2211. The isolation pipe 223 is embedded in the interior of the recovery pipe 24. One end of the isolation pipe 223 is sealingly connected to the isolation end cover 222, and the other end is sealingly connected to the first pipe joint 20a. The liquid outlet pipe 23 is arranged in the second sub-channel 2212 in the interior of the isolation pipe 223, and one end of the liquid outlet pipe 23 extends from the second sub-channel 2212 into the first sub-channel 2211. The interior of the second pipe joint 20b has a joint in fluid communication with the overflow channel 13, and the end of the liquid outlet pipe 23 is connected to the joint, so that the liquid outlet pipe 23 is in fluid communication with the overflow channel 13. The end of the liquid outlet pipe 23 can be interference-fitted to the outer periphery of the joint to form a seal, so as to prevent the cleaning liquid in the liquid outlet pipe 23 from leaking at the position of the end. In addition, the isolation end cover 222 can comprise two detachable parts, one part of the isolation end cover 222 is fixed to the interior of the second pipe joint 20b, and the other part is detachable, so as to assemble the isolation end cover 222 after the liquid outlet pipe 23 is connected, which can facilitate the connection of the liquid outlet pipe 23.

[0061] Please see Figure 6 , Figure 6 is Figure 2 the cross-sectional structure of the cleaning device C-C shown in the schematic view.

[0062] In an embodiment, the host 11 is also electrically connected with the accessory brush 30 through the accessory pipe set 20 to support the electrically powered brush 30 to install electrically powered accessories such as the electrically powered brush. The accessory brush 30 in the embodiment not only can output the cleaning liquid to perform the cleaning work, but also can install the electrically powered accessories such as the electrically powered brush, that is, the accessory brush 30 in the embodiment has rich functions. Specifically, the accessory pipe set 20 further includes a first conductive member 25. The first conductive member 25 is arranged at the second pipe joint 20b. The accessory pipe set 20 further includes a wire 26. The wire 26 is electrically connected with the host 11 and the first conductive member 25 respectively. The accessory brush 30 has a second conductive member 34. At least one of the first conductive member 25 and the second conductive member 34 is arranged around the outer periphery of the second pipe joint 20b. During the rotation of the accessory brush 30 relative to the second pipe joint 20b, the first conductive member 25 and the second conductive member 34 keep in contact to form the electrical connection.

[0063] In the above manner, the first conductive member 25 and the second conductive member 34 in the embodiment form the electrical connection, so that the host 11 is electrically connected with the accessory brush 30 through the wire 26. Moreover, at least one of the first conductive member 25 and the second conductive member 34 in the embodiment is arranged around the outer periphery of the second pipe joint 20b, so that the first conductive member 25 and the second conductive member 34 keep in contact during the rotation of the accessory brush 30, that is, keep the electrical connection relationship. In other words, on the basis of allowing the accessory brush 30 to rotate, the accessory pipe set 20 also makes the host 11 keep the electrical connection relationship with the accessory brush 30, and further supports the electrically powered brush 30 to install the electrically powered accessories.

[0064] Specifically, the first conductive member 25 is arranged around the outer periphery of the second pipe joint 20b, that is, the first conductive member 25 has a complete annular structure. Thus, even if the accessory brush 30 is in the rotating state, the annular first conductive member 25 keeps in contact with the second conductive member 34, so as to make the host 11 keep the electrical connection relationship with the accessory brush 30 on the basis of allowing the accessory brush 30 to rotate, and further support the electrically powered brush 30 to install the electrically powered accessories.

[0065] For the example of the above-mentioned attachment brush 30 comprising the brush body 31 and the brush connector 32, the brush connector 32 is further provided with the avoiding hole 322. The second conductive member 34 comprises the body part 341, the conductive part 342 and the connecting part 343. The body part 341 is fixed in the insertion cavity 321 of the brush connector 32, and the body part 341 can be fixed to the cavity wall of the insertion cavity 321 by screws or other fasteners. The conductive part 342 is connected to one end of the body part 341, and the conductive part 342 extends along the opposite direction of the body part 341 to the first conductive member 25 to contact the first conductive member 25. The conductive part 342 is tangent to the outer peripheral surface of the first conductive member 25, so as to ensure that the conductive part 342 can smoothly slide relative to the first conductive member 25 during the rotation of the attachment brush 30. The connecting part 343 is connected to the end of the body part 341 away from the conductive part 342, and the connecting part 343 passes out of the insertion cavity 321 through the avoiding hole 322 to be electrically connected to the brush body 31, so that the electric accessory mounted on the brush body 31 is electrically connected to the host 11.

[0066] The brush connector 32 comprises the connector body 323 and the conductive member support 324. The conductive member support 324 is detachably assembled to the connector body 323 by screws or other fasteners. The position of the connector body 323 for assembling the conductive member support 324 is hollowed out, and the avoiding hole 322 is provided in the conductive member support 324. The second conductive member 34 is first fixed to the conductive member support 324, and then the conductive member support 324 is assembled to the connector body 323, so that the second conductive member 34 is embedded in the insertion cavity 321, and thus the second conductive member 34 can contact the first conductive member 25.

[0067] In an embodiment, the wire 26 is arranged in the isolation channel 221 of the above-mentioned isolation assembly 22. In this embodiment, the wire 26 is arranged in the isolation channel 221, so that the wire 26 is isolated from the first recovery channel 21, and thus the dirt recovered by the first recovery channel 21 cannot reach the wire 26, thereby avoiding the contact between the dirt recovered by the first recovery channel 21 and the wire 26. It can be understood that the wire 26, the first conductive member 25 and the second conductive member 34 are spaced apart from each other in a predetermined direction, and the overcurrent channel 13 is further insulated from the wire 26, the first conductive member 25 and the second conductive member 34 by the first sealing member 12, which can reduce the risk of short circuit of the wire 26, the first conductive member 25 and the second conductive member 34.

[0068] For example, the wire 26 and the liquid outlet pipe 23 are jointly accommodated in the isolation channel 221, specifically, the wire 26 and the liquid outlet pipe 23 are jointly arranged in the second sub-channel 2212 inside the isolation pipe 223, and one end of the wire 26 also extends from the second sub-channel 2212 to the first sub-channel 2211 inside the second pipe joint 20b. The outer periphery of the second pipe joint 20b can be provided with a groove structure, and the first conductive member 25 is embedded in the groove structure to limit the position of the first conductive member 25 in a predetermined direction. The groove bottom of the groove structure has a through hole, and the wire 26 and the first conductive member 25 are electrically connected through the through hole, for example, the wire 26 and the first conductive member 25 are electrically connected by welding or the like.

[0069] In an embodiment, the number of first conductive members 25, the number of wires 26, and the number of second conductive members 34 are at least two. Each first conductive member 25 and each second conductive member 34 are sequentially and spacedly distributed along a predetermined direction, wherein each first conductive member 25 is electrically connected with a corresponding wire 26, and each first conductive member 25 also maintains contact with a corresponding second conductive member 34. That is, at least two groups of wires 26, first conductive members 25, and second conductive members 34 are provided in the embodiment, and different groups of wires 26, first conductive members 25, and second conductive members 34 are respectively used to realize different circuit functions, for example, to supply power to the electric accessory 30, control the electric accessory to work, etc. Figure 4 and Figure 6 Exemplarily, three groups of wires 26, first conductive members 25, and second conductive members 34 are provided, and Figure 4 Exemplarily, one of the first conductive members 25 is electrically connected with the wire 26.

[0070] Please refer to Figure 7 , Figure 7 is Figure 3 the structural schematic view of the cleaning device N area shown in FIG. 8.

[0071] In an embodiment, the first pipe joint 20a of the accessory pipe group 20 is detachably connected with the host 11. Specifically, the host 11 has a host joint 111, and the host joint 111 is used to be inserted with the first pipe joint 20a to realize detachable connection. In other words, the accessory pipe group 20, the host 11, and the accessory brush 30 in the embodiment are all in detachable manner, which can be conveniently stored. Further, the first pipe joint 20a is provided with a first connecting structure, and the host joint 111 is provided with a second connecting structure; when the host joint 111 and the first pipe joint 20a are inserted with each other, the first connecting structure and the second connecting structure are connected in cooperation. In other words, the first connecting structure and the second connecting structure make the host joint 111 and the first pipe joint 20a detachable in the embodiment, realizing quick release design.

[0072] Furthermore, one of the first connection structure and the second connection structure includes a snap-fit ​​element 271, and the other includes a locking groove 112. When the main unit connector 111 and the first pipe connector 20a are plugged into each other, the snap-fit ​​element 271 and the locking groove 112 engage and lock into place. Figure 7 An example is shown where the first connection structure includes a snap fastener 271 and the second connection structure includes a locking groove 112.

[0073] Of course, in other embodiments of this application, the first connecting structure and the second connecting structure are not limited to the design of the buckle 271 and the buckle groove 112. For example, the first connecting structure and the second connecting structure can also be connected by magnetic attraction or other means, which is not limited here.

[0074] Furthermore, one of the first and second connecting structures also includes an elastic element 272. The latching element 271 includes a rotating portion 2711, a latching portion 2712, and a linkage portion 2713. The rotating portion 2711 is rotatably disposed. The latching portion 2712 is connected to the rotating portion 2711. The linkage portion 2713 is connected to the end of the rotating portion 2711 away from the latching portion 2712. The elastic element 272 drives the rotating portion 2711 to rotate via the linkage portion 2713, causing the latching portion 2712 to rotate with the rotating portion 2711 until it engages with the latching groove 112.

[0075] For example, such as Figure 7 As shown, the rotating part 2711 is rotatably disposed on the first pipe connector 20a. The elastic element 272, such as a spring, is sandwiched between the linkage part 2713 and the first pipe connector 20a. During the process of the main connector 111 and the first pipe connector 20a being inserted into each other, the elastic element 272 can drive the rotating part 2711 to rotate via the linkage part 2713 in response to its own elastic restoring force, thereby causing the latching part 2712 to rotate with the rotating part 2711 until it is engaged in the latching groove 112.

[0076] Of course, in other embodiments of this application, the fastener 271 is not limited to the above-described design of engaging with the locking groove 112 through the elastic element 272. For example, the fastener 271 itself may have a certain elastic deformation capability so that during the process of the main connector 111 and the first pipe connector 20a being inserted into each other, the fastener 271 can engage with the locking groove 112 in response to its own elastic restoring force. This is not limited here.

[0077] In one embodiment, the host connector 111 has an adapter channel 113 connected to the liquid tank. The cleaning device 10 further comprises an adapter 14. When the host connector 111 and the first pipe connector 20a are mutually inserted, the liquid outlet pipe 23 is in fluid communication with the adapter channel 113 through the adapter 14, and the cleaning liquid in the liquid tank is sequentially delivered to the accessory brush 30 through the adapter channel 113, the adapter 14 and the liquid outlet pipe 23.

[0078] For example, Figure 7 For example, the adapter 14 is arranged at the end of the liquid outlet pipe 23, and the adapter 14 can be embedded in the adapter channel 113 with the action of the mutual insertion of the host connector 111 and the first pipe connector 20a. Of course, in other embodiments of the present application, the adapter 14 can also be arranged in the adapter channel 113, which is not limited herein. The adapter 14 is in sealed connection with the liquid outlet pipe 23, and a plurality of sealing rings are arranged on the outer periphery of the adapter 14 to seal the gap between the adapter 14 and the adapter channel 113 after the adapter 14 is embedded in the adapter channel 113.

[0079] In one embodiment, the accessory pipe set 20 further comprises a first conductive connector 28. The first conductive connector 28 is arranged at the first pipe connector 20a, and the wire 26 is in electrical connection with the first conductive connector 28. The host 11 further has a second conductive connector 114. The second conductive connector 114 is arranged at the host connector 111. When the host connector 111 and the first pipe connector 20a are mutually inserted, the first conductive connector 28 and the second conductive connector 114 are in electrical connection, so that the host 11 is in electrical connection with the accessory brush 30 through the wire 26.

[0080] For example, for the above-mentioned arrangement of three sets of wires 26, first conductive members 25 and second conductive members 34, the number of the first conductive connectors 28 and the second conductive connectors 114 is three, each wire 26 is in electrical connection with the corresponding first conductive connector 28, and after the mutual insertion of the host connector 111 and the first pipe connector 20a, each first conductive connector 28 is in electrical connection with the corresponding second conductive connector 114. And, Figure 7 For example, the first conductive connector 28 comprises a conductive column, and the second conductive connector 114 comprises a conductive clamping piece, the conductive clamping piece clamps the conductive column to be arranged, so that the first conductive connector 28 and the second conductive connector 114 are in electrical connection.

[0081] In an embodiment, the first pipe joint 20a has a first recovery channel 21 at least partially inside. The main joint 111 has a second recovery channel 115 inside. The main machine 11 further has a dirt storage tank connected to the second recovery channel 115. After the main joint 111 and the first pipe joint 20a are inserted into each other, the first recovery channel 21 and the second recovery channel 115 are in fluid communication with each other, and the dirt absorbed by the accessory brush 30 is recovered to the dirt storage tank through the first recovery channel 21 and the second recovery channel 115 in sequence, and the user can clean the dirt storage tank regularly.

[0082] Further, the cleaning device 10 further comprises a second sealing member 15. When the main joint 111 and the first pipe joint 20a are inserted into each other, the second sealing member 15 seals the gap between the first pipe joint 20a and the main joint 111. In this way, the second sealing member 15 can improve the vacuum degree of the first recovery channel 21 and the second recovery channel 115, which is conducive to improving the recovery efficiency of the dirt and reducing the risk of dirt leakage. Optionally, the second sealing member 15 can be a sealing ring or the like, which is not limited herein.

[0083] It should be noted that the end of the isolation pipe 223 of the isolation assembly 22 is sealingly connected to the bottom of the first pipe joint 20a. The liquid outlet pipe 23 and the wire 26 of the accessory pipe group 20 extend out of the recovery pipe 24 through the end. The adapter 14 and the first conductive joint 28 are outside the first recovery channel 21, and the adapter 14 is closer to the first recovery channel 21 than the first conductive joint 28, so that the dirt in the first recovery channel 21 does not contact the adapter 14 and the first conductive joint 28. Similarly, the adapter channel 113 and the second conductive joint 114 are outside the second recovery channel 115, and the adapter channel 113 is closer to the second recovery channel 115 than the second conductive joint 114, so that the dirt in the second recovery channel 115 does not contact the adapter channel 113 and the second conductive joint 114.

[0084] In an embodiment, the accessory pipe group 20 is applied to the cleaning device 10. The cleaning device 10 comprises an accessory brush 30, and the accessory pipe group 20 has a pipe joint (i.e., a second pipe joint 20b) for being inserted into the accessory brush 30, and the pipe joint and the accessory brush 30 can rotate relative to each other. When the pipe joint and the accessory brush 30 are inserted into each other, a flow channel 13 is formed between the pipe joint and the accessory brush 30, and the accessory pipe group 20 is in fluid communication with the accessory brush 30 through the flow channel 13.

[0085] It should be noted that the cleaning device 10, the accessory brush 30, and the accessory pipe group 20 of the present embodiment have been described in detail in the above embodiments, and will not be described herein again.
