Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, in particular to a rolling brush assembly and a cleaning floor brush. The present application claims priority from Chinese Patent Application No. 202422390491.7 filed on September 29, 2024 and entitled "Floor Brush Assembly and Cleaning Equipment", the contents of which are hereby incorporated by reference in their entirety. BACKGROUND

[0002] In the prior art, there is a type of cleaning floor brush whose rolling brush is designed to be removable from the rolling brush mounting position. Such a rolling brush assembly can include a lock catch arranged on one side of the floor brush body, and the rolling brush assembly is unlocked from the floor brush body by operating the lock catch. The lock catch can include a sliding assembly, and a locking assembly composed of a lock tongue and a lock groove and the like. However, relying solely on the lock tongue and the lock groove to disengage for disassembling the rolling brush is not stable and reliable enough, and if disengagement fails or encounters other resistance, the rolling brush cannot be disassembled smoothly. The sliding assembly also increases the risk of accidentally unlocking the lock catch when the floor brush is hit, and easily causes the risk of accidental disengagement of the rolling brush during use of the floor brush. On the other hand, after the rolling brush assembly is unlocked from the floor brush body by operating the lock catch, the relative positional relationship between the rolling brush assembly and the floor brush body does not change significantly because the rolling brush assembly is only in a detachable state, which makes it difficult for the user to find the component for applying force to disassemble the rolling brush assembly when actually disassembling the rolling brush assembly, and the operation is difficult and the user's hands are easily dirty, resulting in a poor user experience.

[0051] In order to thoroughly understand the present application, detailed steps and detailed structures will be proposed in the following description in order to explain the technical solutions of the present application. The preferred embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can also have other implementation manners.

[0052] The cleaning floor brush of the present application is one of the component structures of the cleaning equipment. When working, the cleaning equipment travels on the surface to be cleaned, and the cleaning floor brush (mainly the roller brush, mentioned below) contacts and rubs with the surface to be cleaned to clean the surface to be cleaned. Taking the vacuum cleaner as an example, the cleaning equipment can also include a machine body installed on the cleaning floor brush. The cleaning equipment can have a clean water tank and a sewage tank. The clean water tank is used to hold cleaning liquid, and when the cleaning equipment works, the cleaning liquid in the clean water tank is sprayed on the roller brush or the surface to be cleaned in front of the roller brush to cooperate with the roller brush to clean the surface to be cleaned. The sewage (together with particles, hair and other foreign matters) on the surface to be cleaned is collected into the sewage tank, thereby completing the cleaning process.

[0053] The cleaning equipment of the present application is not limited to the vacuum cleaner, but can also be a floor washing machine, an electric mop, a sweeping and mopping all-in-one machine and other cleaning equipment.

[0054] The cleaning floor brush and the roller brush assembly of the present application will be described in detail below. Figures 1-10 The cleaning floor brush and the roller brush assembly of the present application will be described in detail below.

[0055] The present application provides a cleaning floor brush, as shown in Figure 1 , The present application provides a cleaning floor brush, as shown in Figure 2 The present application provides a cleaning floor brush, as shown in Figures 1-4As shown, the axis of the roller brush 1 is along the first direction, the lock catch 3 is movable along the second direction in the lock catch installation position 102, the second direction is perpendicular to the first direction; the lock catch 3 is movable along the second direction to switch between the first position and the second position, the switching includes switching from the first position to the second position, and switching from the second position to the first position. The first position is the position of the lock catch 3 to lock the roller brush 1, at this time the roller brush 1 cannot be taken out from the roller brush installation position 101, and can only rotate along the circumference in the roller brush installation position 101 to perform the action of rubbing the surface to be cleaned, and the second position is the position of the lock catch 3 to unlock the roller brush 1, the roller brush 1 can be taken out from the roller brush installation position 101 to perform maintenance, cleaning, replacement of the brush cloth and the like.

[0056] The conditions for dismounting the roller brush 1 include that the roller brush 1 needs to be replaced when it is worn to a certain extent, or the roller brush 1 needs to be dismounted for cleaning when it is blocked due to dirt, or the roller brush 1 needs to be dismounted for separate cleaning and the like. The roller brush 1 can be taken out from the roller brush installation position 101 of the floor brush main body 100, and can be reinstalled into the roller brush installation position 101. The direction of dismounting and reinstalling the roller brush 1 can be along the axis of the roller brush 1, or can be along other directions.

[0057] As shown, Figures 3-8 The first end of the rotary arm 2 is rotatably connected to the end of the roller brush 1, and the rotary arm 2 can rotate to move the second end away from the surface of the floor brush main body 100. The second end is the opposite end of the first end, and the rotary arm 2 has a locked part 21 and a driven extrusion block 22 at the second end. One end of the lock catch 3 has a locking part 31 and a driving extrusion block 32. The locked part 21 and the locking part 31 are a set of corresponding components, and are designed to have locking structures including but not limited to mutual clamping, buckling, insertion, sticking, magnetic attraction and the like. When the two are matched, the locked part 21 cannot move under the limitation of the locking part 31, and when the two are separated, the movement of the locked part 21 is no longer limited. The driven extrusion block 22 and the driving extrusion block 32 are a set of corresponding components, and when the two are separated, they have no influence on each other, and when the two are close to each other, there is a conflict in space. As the driving extrusion block 32 gradually approaches the driven extrusion block 22, the driving extrusion block 32 can occupy the position of the driven extrusion block 22, forcing the driven extrusion block 22 to move to another position. As shown, Figure 1 When the lock catch 3 is in the first position, the locking part 31 can be connected to the locked part 21, the driven extrusion block 22 is separated from the driving extrusion block 32, and the rotary arm 2 is limited to rotate; as shown, Figures 3-5 When the lock catch 3 is in the second position, the locking part 31 is separated from the locked part 21, and the driving extrusion block 32 can extrude the driven extrusion block 22 to drive the rotary arm 2 to rotate.

[0058] The rotating arm 2 is fixed with the floor brush body 100 through the lock buckle 3. The rotating arm 2 has a locking piece 21 and a driven extrusion block 22 at the second end thereof. When the lock buckle 3 is in the first position, the locking piece 31 can be connected with the locking piece 21, so that the rotating arm 2 is limited to rotate, and the rolling brush assembly is not detached during the normal operation of the floor brush. When the lock buckle 3 is in the second position, the locking piece 31 is separated from the locking piece 21, and the driving extrusion block 32 can extrude the driven extrusion block 22, so that the rotating arm 2 is driven to rotate, and the rolling brush assembly can be conveniently detached and washed after the use of the floor brush is completed. Therefore, when the user uses the rolling brush assembly and the floor brush provided in the embodiment, as shown in Figure 9 , the rotating arm 2 can automatically rotate and pop out, and is fully separated from the floor brush body 100. As shown in Figure 10 , the user does not need to find the detachable position of the rotating arm 2, nor needs to perform any dismounting work on the rotating arm 2, but can detach the rolling brush assembly from the floor brush body 100 by gripping the rotating arm 2.

[0059] In an optional embodiment, as shown in Figure 6 , the rolling brush 1 comprises a rolling brush barrel 11 and a rotating block 12. The rotating block 12 is rotatably connected with the rolling brush barrel 11, and can rotate around the axis of the rolling brush barrel 11. The first end of the rotating arm 2 is rotatably connected with the rotating block 12, and the rotating axis of the rotating arm 2 forms a certain angle with the axis of the rolling brush barrel 11. In this embodiment, since the first end of the rotating arm 2 is rotatably connected with the rotating block 12, and the rotating block 12 itself can rotate around the axis of the rolling brush barrel 11, when the rotating arm 2 is unlocked and rotates around the rotating axis of the rotating arm 2 to pop out, as shown in Figure 9 , the rotating arm 2 can also rotate around the axis of the rolling brush barrel 11 to a position relatively far away from the floor brush body 100, and is fully separated from the floor brush body 100.

[0060] In an optional embodiment, the first end of the rotating arm 2 is provided with an elastic assembly. The elastic assembly makes the rotating arm have a tendency to rotate away from the surface of the floor brush body 100. The beneficial effect of this configuration is that the rotating arm 2 protrudes from the surface of the floor brush body 100 in the unlocked state, which facilitates the user to dismount the rotating arm 2 and the rolling brush 1. It can be understood that in the context of being provided with the elastic assembly, the interference design of the driving extrusion block 32 and the driven extrusion block 22 is a redundant design, which still has beneficial effects. For example, the elastic assembly may have a failure possibility, and the rotating arm 2 may be blocked and unable to automatically rotate out after being unlocked in a specific use scenario. At this time, the design of the driving extrusion block 32 and the driven extrusion block 22 can help the rotating arm 2 to rotate out, and provide additional protection for the smooth dismounting of the rotating arm 2.

[0061] In an optional embodiment, as shown in Figure 6As shown, the rotating block 12 comprises a rotating block body 121 and a rotating shaft 123. The rotating block body 121 has a groove 122 at the end facing the outside of the roller brush 1, and the first end of the rotating arm 2 can partially extend into the groove 122 when the rotating arm 2 is driven to rotate. If the groove 122 is not provided, the first end of the rotating arm 2 will collide with the end of the roller brush 1 when the rotating arm 2 rotates, resulting in the inability to rotate to a larger angle. Therefore, the provision of the groove 122 facilitates the rotating arm 2 to achieve a larger rotatable angle, so as to be far enough from the brush body 100. The rotating shaft 123 is at an angle with the axis of the roller brush barrel 11, so that the rotating arm 2 generates a second rotating direction. The rotating shaft 123 is fixed to the inner wall of the groove 122 and hidden in the roller brush 1, so as to not occupy additional space. One side of the first end of the rotating arm 2 is hinged to the rotating shaft 123, realizing the rotatable connection with the roller brush 1.

[0062] In an optional embodiment, as shown in Figure 6 As shown, the roller brush 1 further comprises a connecting shaft 13 and a bearing 14. The connecting shaft 13 is coaxially fixed to the roller brush barrel 11, and the outer ring of the bearing 14 is connected with the rotating block 12 and the inner ring is connected with the connecting shaft 13. This structure is used to reduce the resistance when the rotating block 12 rotates.

[0063] In an optional embodiment, as shown in Figure 7 , Figure 8 As shown, the driven extrusion block 22 and the driving extrusion block 32 are wedge-shaped blocks, the wedge-shaped blocks extend in the second direction, and the height of the wedge-shaped blocks gradually changes in the first direction. In this embodiment, both the driven extrusion block 22 and the driving extrusion block 32 adopt a wedge-shaped design. This structure can form a set of matching inclined surfaces. When the two inclined surfaces extrude each other, the driven extrusion block 22 can be stably moved under pressure. As the height of the wedge-shaped blocks gradually changes in the first direction, the extrusion force on the driven extrusion block 22 gradually increases during the process that the user actually operates the lock catch 3 to move to the second position. Therefore, the user is more likely to gradually push the lock catch 3 to drive the rotating arm 2 to gradually rotate. It can be understood that in other embodiments, only one of the driven extrusion block 22 and the driving extrusion block 32 can be a wedge-shaped block, and the other shape can be any shape, which can also achieve the effect that the extrusion force on the driven extrusion block 22 gradually increases during the process that the user actually operates the lock catch 3 to move to the second position.

[0064] In an optional embodiment, as shown in Figure 6 As shown, the roller brush assembly further comprises a resilient member 4, and the two ends of the resilient member 4 abut against the lock catch 3 and the inner wall of the lock catch mounting position 102, respectively, so that the lock catch 3 remains in the first position when not subjected to external force. In this embodiment, the function of the resilient member 4 is to keep the lock catch 3 in the first position when not subjected to external force, that is, to ensure that the lock catch 3 locks the rotating arm 2 and ensures that the roller brush 1 does not come off during operation.

[0065] In an optional embodiment, as shown in Figure 6As shown, the lock catch 3 comprises a guide surface 311 extending along the second direction and gradually changing in height along the first direction. Under the action of the guide surface 311, when the locking member 31 is separated from the locked member 21, the lock catch 3 is located at the first position, and the second end of the rotating arm 2 is subjected to a pushing force towards the surface of the cleaning floor brush 100, the locked member 21 can extrude the guide surface 311 to drive the lock catch 3 to move to the second position. In this embodiment, the principle of the guide surface 311 is that it is inclined relative to both the first direction and the second direction, so when the second end of the rotating arm 2 moves towards the surface of the cleaning floor brush 100, i.e. the movement of the second end of the rotating arm 2 in the first direction can cause the guide surface 311 to move in the second direction, realizing the automatic displacement of the lock catch 3, and facilitating the installation of the second end of the rotating arm 2 in place.

[0066] In an optional embodiment, as shown in Figure 6 the end of the locked member 21 towards the lock catch 3 has a slot 211, and the locking member 31 can be inserted into or separated from the slot 211 along the second direction. In this embodiment, the end of the locked member 21 towards the lock catch 3 has a slot 211, which can facilitate the insertion or separation of the locking member 31, so that the locking or unlocking of the rotating arm 2 only needs to control the movement of the lock catch 3 along the second direction, and the structure is simple and easy to realize.

[0067] In an optional embodiment, in the rolling brush assembly of the present embodiment, when the lock catch 3 is located at the first position, the depth of the locking member 31 inserted into the slot 211 along the second direction is L1, and the stroke of the lock catch 3 moving from the first position to the second position is L2, L1 is less than or equal to L2. In this embodiment, the lengths of L1 and L2 are pre-set, and the purpose is to ensure that when the lock catch 3 moves from the first position to the second position, the locking member 31 has been separated or is just separated from the slot 211, so as to ensure that the rotating arm 2 can automatically pop out at the moment of unlocking.

[0068] In an optional embodiment, the L1 of the locking member is designed to be greater than 0.5mm, for example, 0.5mm-5mm, preferably 2mm. In this embodiment, considering that the motor driving the rolling brush 1 to rotate will cause the rolling brush 1 to be subjected to a radial force, including a force along the second direction, which may cause the rotating arm 2 to impact the lock catch 3, in order to avoid the lock catch 3 from being accidentally unlocked due to vibration, L1 is designed to be greater than 0.5mm, for example, 1mm, 1.5mm, 2mm, 3.5mm or 5mm, to reduce the probability of accidental unlocking.

[0069] In an optional embodiment, the cleaning floor brush of the present embodiment, as shown in Figure 2 the surface of the floor brush body 100 protrudes a protrusion 103, as shown in Figure 6As shown, one side of the rotating arm 2 has a recess 23 corresponding to the protrusion 103; when the locking piece 31 is in butt joint with the locked piece 21, the protrusion 103 is embedded in the recess 23, and the movement of the rotating arm 2 in the second direction is limited. In this embodiment, the vibration energy of the rolling brush 1 during operation or when the rotating arm 2 is impacted is transmitted to the protrusion 103 and then consumed by the floor brush body 100, avoiding the transmission of vibration energy to the lock 3, preventing the lock 3 from being triggered to unlock when affected by accidental impact, thereby causing the rolling brush 1 to come out, and also preventing the lock 3 from being worn out and shortening the service life during long-term use of the cleaning floor brush.

[0070] In an optional embodiment, the cleaning floor brush of the present embodiment is as shown in Figure 6 As shown, the outer wall of the protrusion 103 on both sides in the second direction is in close contact with the inner wall of the recess 23, and the protruding direction of the protrusion 103 is along an arc, and the center of the arc is the hinge point of the first end of the rotating arm 2 and the end of the rolling brush 1. In this embodiment, the protruding direction of the protrusion 103 is arranged along the arc, which can conform to the rotating track of the rotating arm 2, so that the outer wall of the protrusion 103 is in closer contact with the inner wall of the recess 23, and the support performance of the rotating arm 2 is improved. It can be understood that in other embodiments, the protruding direction of the protrusion 103 can be along the first direction, but the width of the protrusion 103 needs to be designed to have a certain gap with the inner wall of the recess 23.

[0071] In an optional embodiment, the protrusion height of the protrusion 103 is designed to be greater than 0.5 mm, for example, 0.5 mm to 5 mm, and preferably 2.2 mm, so as to ensure that the impact received by the rotating arm 2 can be fully transmitted to the floor brush body 100.

[0072] In an optional embodiment, the locked piece 21 and the driven extrusion block 22 are components integrally formed with the main body part of the rotating arm 2, and the locking piece 31 and the driving extrusion block 32 are components integrally formed with the main body part of the lock 3.

[0073] It should be understood that the above embodiments are exemplary and are not intended to include all possible implementations. Various modifications and changes can also be made on the basis of the above embodiments without departing from the scope of the present disclosure. Similarly, any combination of the technical features of the above embodiments can also be made to form additional embodiments of the present application which have not been explicitly described. Therefore, the above embodiments only express several implementation manners of the present application, and do not limit the protection scope of the patent of the present application.
