Abstract

This utility model discloses a dual-brush floor brush structure and a vacuum cleaner cleaning device incorporating it. The brush mechanism comprises a pair of roller brushes, including a mounting plate, a drive module, roller brushes, and a cam. The mounting plate is rotatably mounted on a base, and the roller brushes are rotatably mounted on the mounting plate and connected to the drive module. An extension shaft is provided on the roller brush, and a one-way bearing is fixed on the extension shaft. The cam is rotatably mounted on the one-way bearing. When the roller brush rotates forward, the extension shaft drives the one-way bearing to rotate relative to the cam. When the roller brush rotates in reverse, the extension shaft drives the one-way bearing to rotate the cam, which then abuts against the base and supports the roller brush to lift upward. This utility model allows the roller brushes to perform normal cleaning and lifting actions during forward and reverse rotation, respectively. By applying the aforementioned pair of roller brush mechanisms to a vacuum cleaner cleaning device, roller brushes with different functions can be lifted separately to complete the vacuuming and floor cleaning actions.

Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner device technology, and in particular to a floor brush structure with dual roller brushes and a vacuum cleaner cleaning device that integrates suction and removal. Background Technology

[0002] Currently, vacuum cleaners and floor scrubbers on the market are usually used separately. Vacuum cleaners use their roller brushes to dry debris, while floor scrubbers use their roller brushes to mop the floor. Although floor scrubbers can be used as vacuum cleaners to some extent, their cleaning is often not thorough enough. There are many large particles that floor scrubbers cannot pick up, and these still need to be cleaned by a vacuum cleaner.

[0003] Existing technologies also include dual-brush cleaning devices that can simultaneously perform cleaning actions with both front and rear brushes. The cooperation of two brushes with different functions achieves the functions of a vacuum cleaner and a floor scrubber. For example, a water-saving vacuum cleaner and floor scrubber with application number 202411263886.9 has two brushes (cleaning roller and brush roller) that work in sync to perform vacuuming and floor scrubbing actions, but the two brushes cannot rotate independently to perform the corresponding functions. Utility Model Content

[0004] The purpose of this utility model is to provide a dual-brush floor brush structure and a vacuum cleaner cleaning device that integrates vacuuming and washing. Through the combination of cam, one-way bearing and roller brush, the normal cleaning action of the roller brush and the lifting of the roller brush can be realized when the roller brush rotates forward and backward respectively. By applying the above-mentioned pair of roller brush mechanisms to the vacuum cleaner cleaning device, roller brushes with different functions can be lifted to complete the vacuuming action and floor washing action of the roller brush respectively.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a double-roller brush structure, comprising:

[0006] Base

[0007] A pair of roller brush mechanisms, each comprising a mounting plate, a drive module, roller brushes, and a cam, wherein the mounting plate is rotatably mounted on a base, the roller brushes are rotatably mounted on the mounting plate and are drively connected to the drive module mounted on the mounting plate, the roller brushes are provided with an extension shaft, a one-way bearing is fixed on the extension shaft, and the cams are rotatably sleeved on the one-way bearings.

[0008] When the roller brush rotates forward, the extension shaft drives the one-way bearing to rotate relative to the cam. When the roller brush rotates in reverse, the extension shaft drives the one-way bearing to drive the cam to rotate and then abut against the base and support the roller brush to lift upward.

[0009] As a further optimization, the pair of rollers are a vacuuming roller and a floor washing roller. When applied to a vacuum cleaner washing and drying integrated cleaning device, lifting the floor washing roller while keeping the vacuuming roller in the state can complete the vacuuming action, and lifting the vacuuming roller while keeping the floor washing roller in the state can complete the floor washing action.

[0010] As a further optimization, the drive module includes a motor and a transmission assembly. The motor is mounted on the mounting plate, and the transmission assembly is connected to the output end of the motor and the roller brush, respectively.

[0011] As a further optimization, the transmission assembly includes a drive wheel, a driven wheel, and a belt. The drive wheel is located at the output end of the motor, the driven wheel is located on the roller brush, and the belt is sleeved on the drive wheel and the driven wheel.

[0012] As a further optimization, the extension shaft is disposed on the main shaft of the roller brush or on the driven wheel.

[0013] As a further optimization, the cam is provided with a central cavity, and the outer ring of the one-way bearing rotatably abuts against the side wall of the central cavity; the inner ring of the one-way bearing is fixed to the extension shaft.

[0014] As a further optimization, the end of the extension shaft extends out of the one-way bearing and is rotatably mounted on the side wall of the base, which can ensure the rotational stability of the cam.

[0015] As a further optimization, the cam is provided with a sealing plate at least at one end away from the roller brush, and the extension shaft extends out of the sealing plate.

[0016] As a further optimization, the two roller brush mechanisms are arranged symmetrically to achieve a reasonable spatial layout.

[0017] This utility model also provides a vacuum cleaner cleaning device that integrates suction and removal, including the above-mentioned double roller brush structure.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By combining a cam, a one-way bearing, and a roller brush, the normal cleaning action of the roller brush and the lifting of the roller brush can be realized when the roller brush rotates forward and backward, respectively, realizing the relative change of the position of the roller brush and facilitating the combined use of a pair of roller brush mechanisms;

[0020] 2. By applying the above-mentioned pair of roller brush mechanisms to a vacuum cleaner washing and drying integrated cleaning device, roller brushes with different functions can be lifted separately to complete the vacuuming action and floor washing action of the roller brushes respectively.

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1 to 3 As shown, the dual-roller brush structure includes a base 10 and a pair of roller brush mechanisms 20 mounted on the base 10. Each roller brush mechanism 20 includes a mounting plate 21, a drive module 22, roller brushes 23, and a cam 26. The mounting plate 21 is rotatably mounted on the base 10, and the roller brushes 23 are rotatably mounted on the mounting plate 21 and are connected to the drive module 22 mounted on the mounting plate 21. The roller brushes 23 have an extension shaft 24, and a one-way bearing 25 is fixed to the extension shaft 24. The cam 26 is rotatably mounted on the one-way bearing 25.

[0027] When the roller brush 23 rotates forward, the extension shaft 24 drives the one-way bearing 25 to rotate relative to the cam 26. When the roller brush 23 rotates in reverse, the extension shaft 24 drives the one-way bearing 25 to drive the cam 26 to rotate and then abut against the base 10 and support the roller brush 23 to lift upward.

[0028] In this utility model, a roller brush mechanism 20 shall have two mounting plates 21. The two mounting plates 21 are located on opposite sides of the base 10 and can rotate relative to the base 10. Specifically, the base 10 is provided with a support plate 11, and the connecting plate 21 is rotatably mounted on the support plate 11 via a rotating shaft 210. One mounting plate is equipped with a drive module 22 and one end (first end) of the roller brush 23 is rotatably mounted on it. The other mounting plate 21 is rotatably mounted with the other end (second end) of the roller brush 23. For example, the other mounting plate 21 is provided with a connecting bearing 21a, and the second end of the roller brush 23 is mounted on the connecting bearing 21a. With the above structural arrangement, the roller brush 23 can rotate relative to the pair of mounting plates 21 after being driven by the drive module 22. The roller brush 23 can have two states: forward rotation and reverse rotation. When the drive module 22 drives the roller brush 23 to rotate in one direction (defined as the forward rotation direction), the roller brush 23 drives the extension shaft 24 to rotate forward. Since the inner ring 252 of the one-way bearing 25 is fixed to the circumferential sidewall of the extension shaft 24, the one-way bearing 25 rotates synchronously with the extension shaft 24. However, the cam 26, which is provided on the outer ring 251 of the one-way bearing 25, will rotate relative to the one-way bearing 25. That is, the cam 26 rotates relative to the roller brush 23 without affecting the rotation of the roller brush 23, thereby realizing the cleaning action of the roller brush 23. When the drive module 22 drives the roller brush 23 in the opposite direction (defined as the reverse rotation direction), the roller brush 23 rotates in the opposite direction. When the roller brush 23 rotates (in reverse direction), it drives the extension shaft 24 to rotate in reverse. Since the inner ring 252 of the one-way bearing 25 is fixed on the circumferential side wall of the extension shaft 24, the one-way bearing 25 will rotate in reverse synchronously with the extension shaft 24. However, since the outer ring 251 of the one-way bearing 25 can only rotate in one direction, the cam 26 provided on the outer ring 251 of the one-way bearing 25 will not rotate relative to the one-way bearing 25 but will rotate in reverse synchronously with the one-way bearing 25. This makes the cam 26 rotate in reverse synchronously with the roller brush 23. During the rotation of the cam 26, its protrusion will abut against the base 10, thereby lifting the roller brush 23 (detaching from the working surface) and the mounting plate 21. Based on the aforementioned forward and reverse rotation states of the roller brush 23, when the roller brush 23 is driven to rotate forward, it will maintain contact with the working surface (such as the ground) to perform the cleaning action. When the roller brush 23 is driven to rotate in reverse, after rotating by a set angle, the protrusion on the cam 26 can abut against the base 10, thereby lifting the roller brush 23 and the mounting plate 21. The drive module 22 no longer drives the roller brush 23 to rotate in reverse, thus keeping the roller brush 23 in the lifted state. When the roller brush 23 is driven to continue rotating in reverse by a set angle, the protrusion on the cam 26 can disengage from the base 10, so that the roller brush 23 and the mounting plate 21 are no longer supported. The roller brush 23 can return to the state of contact with the working surface. The roller brush 23 can then perform the cleaning action by being driven to rotate forward again.

[0029] When the aforementioned dual-roller brush structure is applied to a vacuum cleaner's integrated vacuuming and descaling cleaning device, to achieve a reasonable layout within the base 10, a pair of roller brush mechanisms 20 are arranged symmetrically along an axis. One roller brush mechanism 20 contains a vacuuming roller brush 23, and the other roller brush mechanism 20 contains a floor-washing roller brush 23. When vacuuming is required, the vacuuming roller brush is driven to rotate forward and remain in contact with the working surface, while the floor-washing roller brush is driven to rotate in reverse and supported to detach from the working surface. The vacuuming action is then completed by the vacuuming roller brush. After the work is finished, the floor-washing roller brush... When the dust roller stops moving, the floor scrubbing roller is driven back to its original position and contacts the work surface. If floor scrubbing is required, the floor scrubbing roller can be driven forward to maintain contact with the work surface, while the dust roller is driven in reverse and supported to detach from the work surface. The floor scrubbing roller then completes the scrubbing action. After completing the work, the floor scrubbing roller stops moving, and the dust roller is driven back to its original position and contacts the work surface. If both the dust roller and the floor scrubbing roller need to work simultaneously, they can be driven to maintain their respective forward rotation and contact with the work surface. The different states of the rollers with different functions are achieved through the driving action of the drive module.

[0030] Preferably, the drive module 22 includes a motor 221 and a transmission assembly 222. The motor 221 is a forward and reverse motor and is mounted on the mounting plate 21. The transmission assembly 222 is connected to the output end of the motor 221 and the roller brush 23 respectively. The forward and reverse rotation of the roller brush 23 is achieved by changing the rotation direction of the motor 221.

[0031] Furthermore, the transmission assembly 222 includes a drive wheel 2221, a driven wheel 2222, and a belt 2223. The drive wheel 2221 is located at the output end of the motor 221, the driven wheel 2222 is located on the roller brush 23, and the belt 2223 is sleeved on the drive wheel 2221 and the driven wheel 2222. The rotation of the output shaft of the motor 221 drives the drive wheel 2221 to rotate, thereby driving the driven wheel 222 to rotate and driving the roller brush 23 to rotate via the belt 2223.

[0032] The extension shaft 24 is disposed on the main shaft of the roller brush 23 or on the driven wheel 2222. Preferably, the main shaft of the roller brush 23 protrudes from the driven wheel 222 to form the extension shaft 24.

[0033] Preferably, the cam 26 has a central cavity 260, and the outer ring 251 of the one-way bearing 25 rotatably abuts against the side wall of the central cavity 260; the inner ring 252 of the one-way bearing 25 is fixed to the circumferential side wall of the extension shaft 24.

[0034] like Figure 4 As shown, in another embodiment of the present invention, the end 241 of the extension shaft 24 extends out of the one-way bearing 25 and is rotatably disposed on the side wall of the base 10, which can ensure the coaxiality of the rotation of the one-way bearing 25 and the stability of the rotation of the cam 26.

[0035] Furthermore, a sealing plate 261 is provided at least at one end of the cam 26 away from the roller brush 23, and the end 241 of the extension shaft 24 extends out of the sealing plate 261. The sealing plate 261 can limit the installation position of the one-way bearing 25.

[0036] In this utility model, the cam 26 is sleeved on the one-way bearing 25, and the one-way bearing 25 is connected to the roller brush 23 through the extension shaft 24. Different rotation states of the roller brush 23 can realize the relative rotation or synchronous rotation of the cam 26, thereby realizing the working state or the supported state of the roller brush 23. Therefore, when a pair of the above-mentioned roller brush mechanisms 20 are applied to the washing and desiccant integrated equipment, the vacuuming action and the floor washing action can be completed respectively by the different roller brushes being in different states.

[0037] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
