[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0049] Throughout the specification and claims, the word "including" is an open-ended term and should be interpreted as "including but not limited to." "Substantially" means that within an acceptable error range, a person skilled in the art can solve the technical problem and substantially achieve the technical effect.

[0050] Furthermore, the term "connected" as used herein encompasses both direct and indirect means of connection. Thus, if a first device is described as being connected to a second device, this means that the first device may be directly connected to the second device or indirectly connected to the second device through another device. The following description of preferred embodiments of the present invention is intended to illustrate the general principles of the invention and is not intended to limit the scope of the invention. The scope of protection of the present invention shall be determined by the appended claims.

[0051] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0052] Those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples without mutual contradiction.

[0053] Figure 1 A schematic diagram of a floor brush provided by an embodiment of the present invention with its main body and two roller brush chambers separated; Figure 2 A schematic diagram of a floor brush body and one of the roller brush chambers in a state of being separated provided by an embodiment of the present invention; Figure 3 Schematic diagram of the combination state of the main body of the floor brush provided by the embodiment of the present invention and one of the roller brush chambers; Figure 1-Figure 3 As shown, the floor brush provided in this embodiment includes: a main body 10 and at least two rolling brush chambers 20.

[0054] Among them, the roller brush chamber 20 includes a cavity 21 and a roller brush (not shown in the figure), the roller brush is rotatably arranged in the cavity 21, and a suction nozzle (not shown in the figure) is provided on the cavity 21; the main body 10 can be selectively detachably connected to one of the two roller brush chambers 20.

[0055] The suction nozzle of the cavity 21 is used to inhale air and suck dust particles, debris, etc. on the surface to be cleaned into the cleaning device.

[0056] The main body 10 can be detachably connected to any of a variety of roller brush chambers 20. Specifically, the main body 10 is detachably connected to the cavity 21 of the roller brush chamber 20. The detachable connection between the main body 10 and the roller brush chamber 20 can include a threaded connection, a snap connection, etc. Of course, the main body 10 and the roller brush chamber 20 can also be connected using other quick-release methods.

[0057] In addition, the main body 10 is provided with an air inlet 101, and a sealing ring 102 may be provided at the edge of the air inlet 101. The shape of the sealing ring 102 can match the edge shape of the air inlet 101. By providing the sealing ring 102 at the air inlet 101, it can effectively prevent the high-speed airflow flowing through the air inlet 101 from impacting the gap between the cavity 21 and the main body 10, causing abnormal noise. This can greatly improve the sealing performance and significantly reduce noise, thus enhancing the user experience.

[0058] The floor brush provided in this embodiment includes a main body and a roller brush cavity, and the roller brush cavity includes a cavity and a roller brush. The main body can be selectively detachably connected to at least one of the two roller brush cavities. As a result, the user can replace the roller brush cavity according to the cleaning site, and the main body selects the required roller brush cavity for connection, avoiding the problem in the prior art that when replacing the roller brush to adapt to different cleaning sites, the cavity needs to be opened to replace the roller brush, thereby resulting in a cumbersome operation process. The present technical solution can directly replace the entire roller brush cavity without opening the cavity and then replacing the roller brush, thereby improving the user experience.

[0059] In this embodiment, the suction nozzles of the cavities 21 are of different sizes, and / or the bristles of the roller brushes 22 are of different heights, and / or the bristles of the roller brushes 22 are of different hardnesses. The cleaning area mentioned in this embodiment can be a floor, a carpet, or a sofa, a bed, etc. Different roller brush cavities 20 can be designed to suit different cleaning areas, and this embodiment does not limit this.

[0060] In this embodiment, the roller brush chamber 20 may include at least: a floor brush, a floor brush chamber 21a for accommodating the floor brush, a carpet brush, and a carpet brush chamber 21b for accommodating the carpet brush; the suction nozzle on the floor brush chamber 22a is larger than the suction nozzle on the carpet brush chamber 22b.

[0061] Figure 6 A schematic structural diagram of one of the roller brush chambers of a floor brush provided in an embodiment of the present invention; Figure 7 A schematic diagram of the structure of another roller brush chamber of a floor brush provided in an embodiment of the present invention; Figure 6 The cavity of the roller brush cavity shown is a carpet brush cavity 22b, and the gap between the suction nozzle and the ground can be between 1mm and 2mm, specifically 1.5mm. Figure 7 The cavity of the roller brush cavity shown is a floor brush cavity 22a, and the gap between the suction nozzle thereon and the ground can be between 26mm and 28mm, specifically 27mm.

[0062] When cleaning floors and carpets, the structures of the suction nozzle and roller brush 22 of the adapted cavity 21 may be different. For floors, the friction and suction of the floor are relatively small, and dust particles and debris are easily sucked into the vacuum cleaner. You can choose a floor brush cavity 21a with a larger suction nozzle and a roller brush cavity 20 formed by a dedicated floor brush to be connected to the main body 10 to clean the floor. This way, large particles on the floor can be sucked in. For carpets, the friction and suction of carpets are relatively large, and small particles such as dust particles and debris are easily accumulated in the fine fluff of the carpet and are difficult to remove. You can choose a cavity 21 with a smaller suction nozzle and a roller brush cavity 20 formed by a dedicated carpet brush to be connected to the main body 10 to clean the carpet. Since the suction nozzle of the roller brush cavity 20 selected at this time is smaller, the overall energy efficiency of the floor brush will be improved, thereby improving the cleaning efficiency of the floor brush.

[0063] Because the size of the floor brush nozzle can be changed by replacing the carpet brush and floor brush, the entire roller brush chamber of the floor brush is made into a detachable structure. The roller brush chamber can be replaced according to the actual cleaning scenario, thus combining the functions of the floor brush and carpet brush into one, so users do not need to purchase two floor brushes, thus saving costs.

[0064] Furthermore, the main body 10 may specifically include a main cavity 11 and a first extension portion 12 extending from one end of the main cavity 11 toward the location of the rolling brush cavity 20 at an angle perpendicular to the main cavity 11 .

[0065] The floor brush of the above embodiment may further include: a driving device 30. Specifically, the driving device 30 may be provided on the main body 10, and the power output shaft of the driving device 30 extends out of the main body 10 for connecting with the roller brush 20 to drive the roller brush 20 to rotate. The driving device 30 may include a motor (not shown in the figure) and a transmission wheel (not shown in the figure). Since the volume of the motor is generally large, the motor can be provided in the main cavity 11, the transmission wheel can be provided at the first extension portion 12, and a power output shaft 31 can be connected to the transmission wheel. The motor can drive the transmission wheel to rotate through a belt, and the power output shaft 31 on the transmission wheel drives the roller brush 22 to rotate. By hiding the motor in the main body 10, the overall volume can be minimized, and the weight of the detachable roller brush chamber 20 can be reduced as much as possible to make it more convenient for users to disassemble the roller brush chamber 20.

[0066] It should be noted that, in order to ensure that the power output shaft 31 can drive the roller brush 22 to rotate and ensure that the roller brush 22 is relatively detached from the power output shaft 31, the power output shaft 31 can be fixed to the roller brush 22 only in the circumferential direction, and can move relative to the roller brush 22 in the axial direction. Specifically, it can be said that the cross section of the power output shaft 31 is non-circular, for example, semicircular, triangular, quadrilateral, hexagonal, etc., or, as Figure 1 and Figure 2As shown, the end of the power take-off shaft 31 is polygonal. Correspondingly, the cross-section of the mounting hole on the roller brush 22 for inserting the power take-off shaft 31 also has a corresponding shape. Alternatively, a radially projecting protrusion may be provided on the power take-off shaft 31, and a groove for receiving the protrusion may be provided on the inner wall of the mounting hole for the roller brush 22. Of course, those skilled in the art may also design other structural forms to achieve circumferential fixation of the power take-off shaft 31 and the roller brush 22, while allowing relative axial movement.

[0067] After the roller brush chamber 20 is installed in place on the main body 10, the relative positions of the roller brush chamber 20 and the main body 10 are fixed, and the power output shaft 31 and the roller brush 22 cannot move axially. When the roller brush chamber 20 is disconnected from the main body 10, the roller brush 22 can move axially relative to the power output shaft 31, and the roller brush 22 can be detached from the power output shaft 31, and the roller brush chamber 20 is removed from the main body 10 as a whole.

[0068] Alternatively, the drive device 30 can be directly disposed within the cavity 20, with the power output shaft 31 of the drive device 30 extending along the axis of the cavity 20 to connect with the roller brush 20 to drive the roller brush 20 to rotate. In this way, the drive device 30 can be a direct-drive motor, eliminating the need for other transmission components. The output shaft of the direct-drive motor directly serves as the power output shaft 31, saving costs. Furthermore, when the roller brush cavity 20 is removed from the main body 10, the roller brush cavity 20 and the drive device 30 can be removed from the main body 10 together.

[0069] like Figures 1 to 3 As shown, a slide can be provided between the cavity 21 and the main body 10, and the slide is used to guide the roller brush 22 to slide into a preset assembly position along the length direction of the main body 10, wherein the preset assembly position is the position on the main body 10 for installing the roller brush cavity 20. Specifically, a slide rail 10a can be provided on the main body 10, and a corresponding slide groove (not shown in the figure) that cooperates with the slide rail can be provided on the cavity 21, or vice versa, a slide groove can be provided on the main body 10, and a slide rail that cooperates with the slide groove can be provided on the cavity 21. The slide rail and the slide groove cooperate to form a slide. By providing the slide, the cavity 21 can be guided to slide into the preset assembly position on the main body 10 along a predetermined direction, which is convenient for user operation.

[0070] Figure 8 A structural diagram of a roller brush chamber provided by an embodiment of the present invention; Figures 1 and 2 ,as well as Figure 8 As shown, the cavity 21 and the main body 10 can be connected by a buckle 40 , and the snap-in direction of the buckle 40 is consistent with the installation direction of the cavity 21 on the main body 10 .

[0071] Specifically, one of the cavity 21 and the main body 10 is provided with a buckle 40, and the other of the cavity 21 and the main body 10 is provided with a slot or a hole 60; the buckle 40 cooperates with the slot or the hole 60 to connect the cavity 21 to the main body 10. The buckle 40 can be provided on the cavity 21 or on the main body 10. In this embodiment, Figures 1 and 2 ,as well as Figure 8 As shown, preferably, the buckle 40 is provided on the cavity 21 , and a clip hole 60 for the buckle 40 to be clipped into is provided on the main body 10 .

[0072] The cavity 21 is connected to the main body 10 through the snap 40. During the installation of the cavity 21 to the main body 10, the cavity 21 can automatically connect to the main body 10. Compared with the method of connecting the cavity 21 to the main body 10 with fasteners, the disassembly and assembly efficiency of the roller brush 20 can be improved.

[0073] In this embodiment, the number of the buckles 40 can be four, such as Figure 8 As shown, the cavity 21 may include a main roller brush cavity 211 and a second extension portion 212 formed at one end of the main roller brush cavity 211. Three buckles 40 may be located on the outer side wall of the main roller brush cavity 211 of the cavity 21 for contact with the main body 10, and the fourth buckle 40 may be located on the second extension portion 212. Of course, it is understood that the number and position of the buckles 40 may be other, and those skilled in the art may design the specific ones, which are not limited in this embodiment.

[0074] like Figure 3 As shown, when the roller brush cavity 20 is in cooperation with the main body 10, the first extension portion 12 of the main body 10 is located at one end of the floor brush, and the second extension portion 212 of the cavity 21 is located at the other end of the floor brush.

[0075] Figure 4 A schematic diagram of the separation state of the interior of the main body of a floor brush provided by an embodiment of the present invention and one of the roller brush chambers; Figure 5 A schematic diagram of the combined state of the interior of the main body of a floor brush and one of the roller brush chambers provided by an embodiment of the present invention; Figure 9 Schematic diagram of the state of the main body and locking device of the floor brush provided in an embodiment of the present invention Figure 1 ; Figure 10 Schematic diagram of the state of the main body and locking device of the floor brush provided in an embodiment of the present invention Figure 2 .like Figures 4 and 5 ,as well as Figures 9 and 10 As shown, the floor brush may further include a locking device 50 , which may be specifically provided at an end of the main body 10 away from the first extension portion 12 and located within the main cavity 11 of the main body 10 .

[0076] The locking device 50 may include a locking member 51 and an unlocking member 52 ; the main body 10 and the cavity 21 may include a locked state and an unlocked state.

[0077] In the locked state, the locking member 51 is at least partially inserted into the cavity 21. It is understood that the cavity 21 may be provided with a slot or jack (not shown) for inserting the locking member 51. The insertion direction of the locking member 51 forms an angle with the installation direction A of the cavity 21. This allows the locking member 51 to lock the cavity 21 and prevent it from loosening from the buckle 40. Preferably, the angle between the insertion direction of the locking member 51 and the installation direction A of the cavity 21 is 90°.

[0078] During the switching process from the locked state to the unlocked state, the unlocking member 52 drives the locking member 51 to move in a direction away from the cavity 21 until the locking member 51 is relatively disengaged from the cavity 21 and maintains the locking member 51 in a preset unlocking position.

[0079] Figure 9 This is the state where the locking device 50 locks the cavity 21 . Figure 10 The state in which the locking device 50 unlocks the cavity 21. Specifically, a driving portion 521 and a holding portion 522 may be provided on the unlocking member 52, and a matching portion (not shown in the figure) may be provided on the locking member 51. The driving portion 521 is used to receive external force to drive the holding portion 522 to move toward the locking member 51. The driving portion 521 may be a pressing end on the unlocking member 52 for the user to press, and the holding portion 522 may be located at the end of the unlocking member 52. The user may press the driving portion 521 in the opposite direction of the installation direction A along the cavity 21, and the driving portion 521 drives the holding portion 522 to move toward the locking member 51. The holding portion 522 pushes the locking member 51 before moving to cooperate with the matching portion, so that the locking member 51 moves in the direction of separation from the cavity 21 until the holding portion 522 cooperates with the matching portion.

[0080] like Figure 9 As shown, the retaining portion 522 can be in the shape of a barb. The retaining portion 522 is located on the side of the unlocking member 52 away from the cavity 21. The retaining portion 522 includes a push surface 5221 and a retaining surface 5222. Preferably, the push surface 5221 can be an inclined surface or an arcuate surface. The mating portion can be a slot or a hole. As the retaining portion 522 moves toward the locking member 51, the push surface 5221 contacts the edge of the mating portion to push against the locking member 51. The retaining surface 5222 is used to hook the edge of the mating portion to maintain the locking member 51 in the preset unlocked position.

[0081] The locking device 50 may further include a locking elastic member a, which is disposed between the locking member 51 and the main body 10. The retraction direction of the locking elastic member a is consistent with the movement direction of the locking member 51. Specifically, one end of the locking elastic member a may be connected to one end of the locking member 51, and the other end of the locking elastic member a may be connected to or abut the main body 10. The locking elastic member a may be a telescopic spring, or alternatively, a rubber elastic member.

[0082] During the installation of the cavity 21 onto the main body 10, the locking member 51 can be pushed against the side of the cavity 21 and move away from the cavity 21. The locking elastic member a undergoes elastic deformation, driving the locking member 51 to move until the retaining portion 522 disengages from the mating portion. After the retaining portion 522 disengages from the mating portion, the locking elastic member a recovers its deformation and drives the locking member to be inserted into the cavity, thereby entering a locked state. The elastic deformation of the locking elastic member a can be compression or tension, and correspondingly, the recovery of the locking elastic member a can be extension from the compressed state to the initial state, or retraction from the tensioned state to the initial state.

[0083] The locking device 50 may further include an unlocking elastic member b; the unlocking elastic member b may be disposed between the unlocking member 52 and the main body 10, with the direction of expansion and contraction of the unlocking elastic member b coinciding with the direction of movement of the unlocking member 52. Specifically, one end of the unlocking elastic member b may be connected to one end of the unlocking member 52, while the other end of the unlocking elastic member b may be connected to or abut against the main body 10. The unlocking elastic member b may be a telescopic spring, or alternatively, a rubber elastic member. The unlocking elastic member b is used to drive the retaining portion 522 away from the locking member 51 after the retaining portion 522 disengages from the mating portion.

[0084] The unlocking process and locking process of the locking device provided in this embodiment are described in detail below:

[0085] Locking process: Figure 9 As shown, when the cavity 21 slides onto the main body 10 along the guide rail along the installation direction A, the side of the cavity 21 abuts against the end of the locking member 51, causing the locking member 51 to move away from the cavity 21. The locking elastic member a is continuously compressed, and the retaining portion 522 of the unlocking member 52 disengages from the mating portion. When the cavity 21 moves to a position where the slot or hole on the cavity 21 reaches the end of the locking member 51, the locking member 51, under the action of the elastic restoring force of the locking elastic member a, drives the locking member 51 to rebound into the slot or hole inserted into the cavity 21, thereby completing the locking process. The entire locking process is completely automatically achieved through the installation of the cavity 21. Once the cavity 21 is securely in place, it is automatically locked, resulting in high assembly efficiency.

[0086] Unlocking process: Figure 10As shown, the user can press the driving part 521 of the unlocking member 52, and the driving part 521 drives the unlocking member 52 to move as a whole toward the direction of the locking member 51, and compresses the unlocking locking member b. Since the holding part 522 of the unlocking member 52 is in the shape of a barb, the pushing surface 5221 of the holding part 522 continuously pushes the edge of the matching part, so that the locking member 51 withdraws from the slot or hole of the cavity 21 until the holding surface 5222 of the holding part 522 enters the matching part and contacts the edge of the matching part, locking the locking member 51 in the preset unlocking position. At this time, the cavity 21 can be pulled out from the main body 10 in the direction opposite to the installation direction A.

[0087] It is understood that when the cavity 21 is removed from the main body 10, the side of the cavity 21 can also press against the locking member 51 again, causing the retaining portion 522 of the unlocking member 52 to disengage from the mating portion, and the unlocking elastic member b drives the retaining portion 522 to return to its initial position. At this time, since the retaining groove or retaining hole of the cavity 21 has passed the locking member 51, the locking member 51 is unable to lock the cavity 21, and the cavity 21 can be smoothly removed.

[0088] Example 2

[0089] This embodiment provides a cleaning device, including a main unit and the floor brush provided in the above embodiment.

[0090] The cleaning device provided in this embodiment may be, for example, a vacuum cleaner. The structure and function of the floor brush in the cleaning device are the same as those in the first embodiment.
