[0070] The floor brush assembly 200 according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0071] 1 to 15 , the floor brush assembly 200 according to an embodiment of the present application may include: a floor brush body 50 and a suction nozzle assembly 100 .

[0072] Specifically, the suction nozzle assembly 100 is fixedly or detachably connected to the floor brush body 50, and the floor brush assembly 200 can be assembled. When negative pressure is provided to the suction nozzle assembly 100, the dust, garbage or liquid on the ground can be sucked into the floor brush assembly 200 through the suction nozzle assembly 100, realizing the adsorption function, which is convenient for cleaning the floor or carpet, etc., and is conducive to improving cleaning efficiency, thereby improving the user experience.

[0073] In addition, when the suction nozzle assembly 100 and the floor brush body 50 are detachable, it is convenient to clean the dirt in the suction nozzle assembly 100, making it more convenient for the user to clean the dirt in the suction nozzle assembly 100, and ensuring smooth airflow in the suction nozzle assembly 100, which is conducive to improving cleaning efficiency.

[0074] According to the suction nozzle assembly 100 of the embodiment of the present application, the floor brush assembly 200 can be assembled by fixedly or detachably connecting the suction nozzle assembly 100 to the floor brush body 50. When negative pressure is provided to the suction nozzle assembly 100, dust, garbage or liquid on the ground can be sucked into the floor brush assembly 200 through the suction nozzle assembly 100 to realize the adsorption function, which is convenient for cleaning the floor or carpet, etc., and is beneficial to improving the cleaning efficiency. Moreover, when the suction nozzle assembly 100 and the floor brush body 50 are detachable, it is convenient to clean the dirt in the suction nozzle assembly 100, which can improve the user experience.

[0075] In some embodiments of the present application, as shown in Figures 1 to 15, the nozzle assembly 100 includes a nozzle lower cover 10 and a nozzle upper cover 20, and an air duct 30 is defined between the nozzle upper cover 20 and the nozzle lower cover 10. By providing negative pressure to the nozzle assembly 100, the nozzle assembly 100 can suck dust, garbage or liquid on the ground into the cleaning device 300 through the air duct 30, thereby realizing the adsorption function and facilitating the cleaning of the ground or carpet.

[0076] In some related technologies, the nozzle assembly is an inseparable part, that is, the upper cover and the lower cover of the nozzle are inseparable, which makes it difficult to clean the nozzle assembly and is not conducive to cleaning the air duct. Hair, carpet hair and other dirt are easily left in the air duct, causing odors such as stink, and easily affecting the airflow of the air duct, reducing the cleaning efficiency of the cleaning equipment.

[0077] In other related technologies, the nozzle assembly is a detachable part, that is, the nozzle upper cover and the nozzle lower cover are completely detachable. During the use of the nozzle assembly, the nozzle upper cover or the nozzle lower cover is prone to fall off frequently, affecting the user experience.

[0078] 6-12 and 15, the nozzle upper cover 20 has a rotating portion 21 and a connecting portion 22. The rotating portion 21 is rotatably connected to the nozzle lower cover 10, so that the rotating portion 21 can rotate relative to the nozzle lower cover 10, and the connecting portion 22 is detachably connected to the nozzle lower cover 10, that is, the nozzle upper cover 20 and the nozzle lower cover 10 can be disassembled and the two will not be completely separated. The connecting portion 22 is detachable from the nozzle lower cover 10 and the rotating portion 21 is rotatable relative to the nozzle lower cover 10, so that the nozzle upper cover 20 and the nozzle lower cover 10 can be opened, which is convenient for cleaning the dirt in the air duct 30, making it more convenient for users to clean the dirt between the nozzle upper cover 20 and the nozzle lower cover 10, ensuring smooth airflow in the air duct 30, and helping to improve the cleaning efficiency of the cleaning device 300.

[0079] At the same time, the connection between the rotating part 21 and the lower cover 10 of the nozzle can prevent the nozzle upper cover 20 and the lower cover 10 from frequently falling off, ensuring the normal operation of the nozzle assembly 100, which is beneficial to improving the user experience and avoiding problems such as loss.

[0080] In some embodiments, the nozzle lower cover 10 can be a transparent part, which facilitates observation of the work in the air duct 30, and can promptly discover problems such as abnormal work, ensure the normal operation of the nozzle assembly 100, and ensure the cleaning effect.

[0081] In some embodiments, the rotating portion 21 and the connecting portion 22 are arranged relative to each other; or, there are multiple connecting portions 22 (greater than or equal to two), and the rotating portion 21 and multiple connecting portions 22 are arranged at intervals in the circumferential direction of the suction nozzle upper cover 20. Both can be arranged according to actual conditions, can meet different assembly requirements, ensure that the suction nozzle upper cover 20 and the suction nozzle lower cover 10 are reliably connected, and facilitate the disassembly and cleaning of the suction nozzle upper cover 20 and the suction nozzle lower cover 10.

[0082] In some embodiments of the present application, as shown in Figures 5 to 12, the rotating part 21 is located at the air inlet end of the air duct 30, and the connecting part 22 is located at the air outlet end of the air duct 30, which is convenient for cleaning the dirt in the air duct 30 when the connecting part 22 is disassembled from the suction nozzle lower cover 10, while ensuring that the suction nozzle upper cover 20 and the suction nozzle lower cover 10 are connected more reliably to avoid falling off, and the user can easily remove the connecting part 22 from the suction nozzle lower cover 10, making disassembly more convenient and conducive to improving the user's experience; or, the rotating part 21 is located at the air outlet end of the air duct 30, and the connecting part 22 is located at the air inlet end of the air duct 30, which is convenient for cleaning the dirt in the air duct 30 when the connecting part 22 is disassembled from the suction nozzle lower cover 10, while ensuring that the suction nozzle upper cover 20 and the suction nozzle lower cover 10 are connected more reliably to avoid falling off.

[0083] In the embodiment of the present application, the specific structure of the connection between the rotating portion 21 and the nozzle lower cover 10 can be set according to actual conditions.

[0084] For example, in some embodiments, a rotating shaft is provided on the rotating portion 21, and a rotating hole is provided on the suction nozzle lower cover 10. The rotating shaft is rotatably provided in the rotating hole, so that the suction nozzle upper cover 20 can be rotated relative to the suction nozzle lower cover 10. Thus, the rotation shaft and the rotating hole cooperate with each other to limit the suction nozzle upper cover 20 from moving relative to the suction nozzle lower cover 10 in a direction away from the suction nozzle lower cover 10 (for example, upward as shown in Figure 6), thereby ensuring reliable limiting, and realizing the requirement that the rotating portion 21 is connected to the suction nozzle lower cover 10 and can be rotated relative to the suction nozzle lower cover 10, and the structure is simple, which is convenient for processing and manufacturing.

[0085] It should be noted that, for the convenience of description, the directions such as "up", "down", "front", "back", "left" and "right" in this application are based on the direction relationships shown in the accompanying drawings, and are not limitations on the directions in actual application.

[0086] Of course, the setting position of the rotating shaft can also be set on the lower cover 10 of the suction nozzle. Specifically, a rotating shaft is provided on the lower cover 10 of the suction nozzle, and a rotating hole is provided on the rotating part 21. The rotating shaft can be rotatably provided in the rotating hole so that the upper cover 20 of the suction nozzle can rotate relative to the lower cover 10 of the suction nozzle. This is also within the protection scope of the present application.

[0087] In some embodiments, as shown in Figures 5-10 and 15, a seal 40 is provided between the nozzle upper cover 20 and the nozzle lower cover 10, which can form a closed air duct 30 between the nozzle upper cover 20 and the nozzle lower cover 10, thereby preventing external air from entering the air duct 30 and affecting the normal operation of the nozzle assembly 100, and preventing problems such as dirt in the air duct 30 flowing out through the gaps, thereby ensuring that the nozzle assembly 100 works reliably and has a good cleaning effect.

[0088] For example, in some embodiments, as shown in Figure 7, the seal 40 is provided on the nozzle upper cover 20, and the nozzle lower cover 10 is provided with a fixing hole 11. The seal 40 is provided with a fixing portion 41 at one end close to the rotating portion 21. The fixing portion 41 is clamped in the fixing hole 11, so that the nozzle upper cover 20 can be rotated relative to the nozzle lower cover 10. Therefore, the fixing portion 41 cooperates with the fixing hole 11 to limit the nozzle upper cover 20 from moving relative to the nozzle lower cover 10 in a direction away from the nozzle lower cover 10, thereby ensuring reliable limiting. Moreover, due to the flexibility of the seal 40, the rotating portion 21 can be connected to the nozzle lower cover 10 while the rotating portion 21 can be rotated relative to the nozzle lower cover 10. The structure is simple, easy to process and manufacture, and conducive to reducing production costs.

[0089] 7 ) is abutted against the side of the nozzle lower cover 10 away from the seal 40, ensuring that the fixing portion 41 is reliably fixed on the nozzle lower cover 10, and can limit the nozzle upper cover 20 from moving relative to the nozzle lower cover 10 in a direction away from the nozzle lower cover 10, ensuring reliable limiting, and allowing the rotating portion 21 to rotate relative to the nozzle lower cover 10. The structure of the fixing portion 41 is simple, easy to process and manufacture, and conducive to reducing production costs.

[0090] Of course, the setting position of the seal 40 can also be set on the lower cover 10 of the nozzle. Specifically, the seal 40 is provided on the lower cover 10 of the nozzle, and a fixing hole 11 is provided on the upper cover 20 of the nozzle. The end of the seal 40 close to the rotating part 21 is provided with a fixing part 41, and the fixing part 41 is clamped in the fixing hole 11 so that the upper cover 20 of the nozzle can rotate relative to the lower cover 10 of the nozzle. This is also within the protection scope of the present application.

[0091] In some embodiments, the seal 40 is connected to the nozzle upper cover 20 by an adhesive to achieve the connection between the seal 40 and the nozzle upper cover 20, ensuring that the seal 40 is reliably fixed on the nozzle upper cover 20. Then, the nozzle upper cover 20 and the nozzle lower cover 10 are assembled to achieve the assembly of the nozzle assembly 100, ensuring that the air duct 30 is reliably sealed, and the seal 40 is not easily removed from the nozzle upper cover 20, which facilitates the subsequent cleaning and assembly of the nozzle upper cover 20 and the nozzle lower cover 10, and is beneficial to improving the user experience.

[0092] In the embodiment of the present application, the specific connection method of the connecting portion 22 and the nozzle lower cover 10 can be set according to actual conditions. For example, the connecting portion 22 and the nozzle lower cover 10 can be connected by fasteners.

[0093] For example, in some embodiments, the connecting portion 22 and the nozzle lower cover 10 are snap-connected to limit the rotation of the nozzle upper cover 20 relative to the nozzle lower cover 10, ensuring a reliable connection and facilitating disassembly, thereby improving the user experience.

[0094] In some specific embodiments, as shown in Figures 8 and 15, the nozzle lower cover 10 is provided with a snap-fit ​​groove 12, and the connecting portion 22 is provided with a hook 23. The connection between the hook 23 and the connecting portion 22 is spaced apart from the ends of the hook 23 in the length direction (for example, the up and down direction shown in Figure 8). One end of the hook 23 is snap-fitted with the snap-fit ​​groove 12, which can achieve a snap-fit ​​connection between the connecting portion 22 and the nozzle lower cover 10, restricting the rotation of the nozzle upper cover 20 relative to the nozzle lower cover 10, ensuring a reliable connection, and having a simple structure, which is easy to process and manufacture. At the same time, by pressing the end of the hook 23 away from the snap-fit ​​groove 12 and rotating it toward the rotating portion 21, the end of the hook 23 can be disengaged from the snap-fit ​​groove 12, thereby achieving disassembly of the connecting portion 22 and the nozzle lower cover 10, making disassembly more convenient and conducive to improving the user experience.

[0095] In some embodiments of the present application, as shown in Figures 7, 10, and 12, the nozzle lower cover 10 is provided with a suction port 13, which is connected to the air duct 30. When negative pressure is applied to the nozzle assembly 100, dust, garbage, or liquid on the ground can enter the air duct 30 through the suction port 13 and be sucked into the cleaning device 300 through the air duct 30, thereby achieving an adsorption function and facilitating cleaning of the floor or carpet. In addition, the nozzle upper cover 20 is provided with a reinforcement portion 24, which extends into the suction port 13 and can achieve positioning of the nozzle upper cover 20, ensuring reliable assembly and making the connection between the nozzle upper cover 20 and the nozzle lower cover 10 more reliable.

[0096] In some embodiments, as shown in Figure 5, there can be multiple reinforcement parts 24 (greater than or equal to two), and the multiple reinforcement parts 24 are spaced apart along the length direction of the suction port 13 (for example, the left and right direction shown in Figure 5). The multiple reinforcement parts 24 can all be extended into the suction port 13, and can achieve guidance and positioning of different positions of the suction nozzle upper cover 20, ensuring that the connection between the suction nozzle upper cover 20 and the suction nozzle lower cover 10 is reliable.

[0097] In some embodiments where a fixing hole 11 is provided on the nozzle lower cover 10, as shown in FIG5 , there may be a plurality of fixing holes 11, and the plurality of fixing holes 11 are spaced apart along the length direction of the suction port 13. There are a plurality of fixing portions 41 corresponding one to one to the fixing holes 11. By cooperating with the plurality of fixing portions 41 and the plurality of fixing holes 11, the connection between the seal 40 and the nozzle lower cover 10 at a plurality of different positions is achieved, thereby ensuring that the seal 40 and the nozzle lower cover 10 are reliably connected.

[0098] In the embodiments of the present application, the number of fixing holes 11 can be flexibly set according to actual conditions. For example, the number of fixing holes 11 can be three as shown in Figure 5, or it can be two, four, five, six or more, which are all within the scope of protection of the present application.

[0099] According to some embodiments of the present application, as shown in FIG10 , a first positioning post 25 is provided on one side of the nozzle upper cover 20 facing the nozzle lower cover 10 (e.g., the rear side shown in FIG4 ), and a positioning groove 14 is provided on the nozzle lower cover 10. Thus, when the connecting portion 22 is connected to the nozzle lower cover 10, the positioning groove 14 cooperates with the first positioning post 25 to facilitate the guidance and positioning of the nozzle upper cover 20 and the nozzle lower cover 10, thereby facilitating the assembly of the nozzle upper cover 20 and the nozzle lower cover 10. In addition, the positioning groove 14 can limit the first positioning post 25 to prevent the nozzle upper cover 20 from rotating relative to the nozzle lower cover 10, thereby ensuring reliable operation of the nozzle assembly 100.

[0100] In some embodiments where a reinforcement portion 24 is provided on the nozzle cover 20, as shown in FIG10 , the extension direction of the first positioning column 25 is perpendicular to the extension direction of the reinforcement portion 24. Thus, the first positioning column 25 cooperates with the positioning groove 14 and the reinforcement portion 24 extends into the suction port 13, thereby facilitating the assembly of the nozzle cover 20 and enabling the nozzle cover 20 to be limited in multiple directions, thereby avoiding problems such as shaking of the nozzle cover 20.

[0101] In some embodiments, as shown in Figure 5, there can be multiple first positioning columns 25, and multiple first positioning columns 25 are arranged at intervals on the nozzle cover 20. There are multiple positioning grooves 14 that correspond one to one with the first positioning columns 25.
