DETAILED DESCRIPTION

[0054] The embodiments of the present application will be further described below in conjunction with the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0055] It should be noted that in the embodiments of the present application, the orientation or position relationship of "upper", "lower" and the like is based on the orientation or position relationship shown in the drawings. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. The present application will be further described in detail below in conjunction with the drawings and specific embodiments. In addition, the terms "first", "second", "third" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0056] In the description of the embodiments of the present application, it should be noted that unless otherwise explicitly specified and limited, the term "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium. For those skilled in the art, the specific meaning of the above-mentioned terms in the embodiments of the present application can be understood according to the specific circumstances.

[0057] In the embodiments of the present application, unless otherwise explicitly specified and limited, the first feature "on" the second feature can be that the first feature and the second feature are in direct contact, or the first feature and the second feature are in indirect contact through an intermediate medium.

[0058] In the description of the specification, the description of the terms "some embodiments", "exemplarily" and the like means that the specific features, structures, materials or characteristics described in combination with the embodiments or examples are contained in at least one embodiment or example of the embodiments of the present application. In the specification, the exemplary description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any suitable manner in any one or more embodiments or examples. In addition, those skilled in the art can combine different embodiments or examples described in the present application and the features of different embodiments or examples without contradiction.

[0059] In the related art, the cleaning device drives the cleaning assembly to rotate by the motor, and drives the cleaning piece to clean the ground. Generally, the motor is controlled by a program to rotate in one direction, so that the cleaning piece rotates in one direction during cleaning operation, which facilitates sweeping garbage to the dust suction port and reduces the consumption of the cleaning piece. When the cleaning piece needs to be lifted or retracted, an additional driving motor needs to be provided.

[0060] Therefore, the embodiments of the present application provide a cleaning module, which can make the cleaning assembly rotate in one direction during cleaning operation, so as to clean the surface to be cleaned. The surface to be cleaned includes but is not limited to ground, carpet, floor, etc., which are collectively referred to as ground below.

[0061] The cleaning module can be used in a cleaning device. Exemplarily, the cleaning device includes a device main body for providing a mounting position of each structure in the cleaning device. The shell structure of the device main body can be a square disc or a circular disc. The cleaning module is arranged on the device main body.

[0062] The cleaning module can be used in a cleaning device such as a sweeper to sweep garbage, which includes but is not limited to hair, dust, debris, etc. The cleaning module can be a side brush module or a main brush module. When the cleaning module is a side brush module, the cleaning device can also be provided with a main brush module. The cleaning module can cooperate with the main brush module to perform separate or combined cleaning operation.

[0063] Please refer to Figures 1-3 The embodiments of the present application provide a cleaning module 100, which includes a cleaning assembly 10, a power assembly 20 and a one-way locking piece 30. The power assembly 20 is drivingly connected with the cleaning assembly 10, and is used to drive the cleaning assembly 10 to rotate. The one-way locking piece 30 connects the power assembly 20 and the cleaning assembly 10, so that the cleaning assembly 10 can rotate in a first direction R and is locked when rotating in a second direction S. The first direction R and the second direction S are opposite.

[0064] The first direction R and the second direction S refer to the direction of rotation. The first direction R can be one of the clockwise direction or the counterclockwise direction. For example, please refer to Figure 2When the first direction R is the clockwise direction, the second direction S is the counterclockwise direction.

[0065] Exemplarily, the cleaning assembly 10 can include a cleaning piece 11, a rotating shell 12, and a rotating disc 13. The rotating shell 12 has a first through hole 12a, and the rotating disc 13 is arranged in the rotating shell 12. The power assembly 20 is drivingly connected with the rotating disc 13. One end of the cleaning piece 11 is connected to the rotating disc 13 and located in the rotating shell 12, and the other end of the cleaning piece 11 is exposed outside the rotating shell 12 through the first through hole 12a. The cleaning piece 11 can be a side brush to achieve a cleaning function, or the cleaning piece 11 can be a mop to achieve a mopping function, etc. Specifically, different functional cleaning pieces 11 can be arranged according to cleaning requirements to achieve the cleaning purpose. The cleaning piece 11 can be a side brush or a main brush, which can be in the form of bristles to achieve a cleaning function, or can be in the form of a mop strip to achieve a mopping function. The cleaning piece 11 can be made of a hard material or a soft material. Both the hard material and the soft material can have a certain deformation under an external force, and the deformation degree of the hard material is smaller than that of the soft material. Exemplarily, the cleaning piece 11 can be made of a hard material, such as a hard plastic side brush, which has a stronger cleaning ability and a smaller deformation degree, and can be suitable for cleaning a hard floor. Alternatively, the cleaning piece 11 can be made of a soft material, such as a soft plastic side brush, a soft rubber side brush, or a silica gel side brush, which has a small friction force against the ground and is not easy to scratch the ground, and can be suitable for cleaning a carpet, a high-grade wood floor, or other easily scratched floors.

[0066] The power assembly 20 includes a power part 21 drivingly connected with the cleaning assembly 10 for driving the cleaning assembly 10 to rotate. The power part 21 can have a bidirectional driving function. Under the driving action of the power part 21, the cleaning assembly 10 rotates along the first direction R to collect dust, debris, hair, and other garbage on the ground. By switching the driving direction of the power part 21, the power part 21 can drive the cleaning assembly 10 to rotate along the second direction S.

[0067] The one-way locking piece 30 is used to connect the power assembly 20 and the cleaning assembly 10, and has a locking state and an unlocking state, so that the cleaning assembly 10 can rotate along the first direction R and is locked when rotating along the second direction S. When the cleaning assembly 10 does not perform a cleaning operation, the one-way locking piece 30 is in the locking state, which locks the rotation of the cleaning assembly 10 along the second direction S. When the cleaning assembly 10 needs to perform a cleaning operation, the power assembly 20 can drive the cleaning assembly 10 to rotate along the first direction R, and the one-way locking piece 30 is in the unlocking state, so that the cleaning assembly 10 can normally perform the cleaning operation. When the cleaning operation is completed and the cleaning piece 11 needs to be lifted, the power part 21 drives the cleaning assembly 10 to rotate along the second direction S, and the one-way locking piece 30 returns to the locking state, which locks the further rotation of the cleaning assembly 10 along the second direction S.

[0068] The one-way locking member 30 can be a one-way bearing, a ratchet mechanism, a grooved wheel mechanism or a tensioning mechanism. For example, the one-way locking member 30 is a tensioning mechanism including a tensioning member 31, which can be loosened to allow the cleaning assembly 10 to rotate when the power assembly 20 drives the cleaning assembly 10 to rotate in the first direction R, and which can be locked to lock the cleaning assembly 10, i.e. the cleaning assembly 10 can no longer rotate, when the power assembly 20 drives the cleaning assembly 10 to rotate in the second direction S. The tensioning member 31 can be a tensioning spring, a tensioning oil cylinder, a tensioning gas cylinder or a tensioning electric cylinder.

[0069] In this way, the locking achieved by the tensioning member 31 can absorb a certain impact force, which helps to improve the impact resistance and can reduce the vibration and noise generated during rotation.

[0070] It should be noted that when the power assembly 20 drives the cleaning assembly 10 to rotate in the second direction S, the time when the one-way locking member 30 acts on the cleaning assembly 10 can be synchronized with the power switching of the power assembly 20, or can be delayed from the power switching of the power assembly 20, i.e. a small period of time after the power switching of the power assembly 20, the cleaning member 11 of the cleaning assembly 10 is lifted to be away from the ground. The lifting of the cleaning member 11 can be directly upward, or the cleaning member 11 can be retracted relative to the rotating shell 12. During the lifting of the cleaning member 11 by rotating the cleaning assembly 10 in the second direction S, the force of the one-way locking member 30 increases to hinder the continuous rotation of the cleaning assembly 10, so that the cleaning assembly 10 is locked.

[0071] The cleaning module provided by the embodiments of the present application connects the power assembly 20 and the cleaning assembly 10 through the one-way locking member 30, so that the cleaning assembly 10 rotates in the first direction R and is locked when rotating in the second direction S. This allows the cleaning assembly 10 to sweep the garbage into the dust suction port of the cleaning device, which can reduce the wear of the cleaning member and improve the service life. At the same time, if necessary, the bidirectional driving performance of the power assembly 20 can be used, and the power switching can be used to drive the cleaning assembly 10 to rotate in the opposite direction, for example, to lift or at least partially retract the cleaning member 11 into the rotating shell 12, so that the cleaning member 11 is away from the ground. By using the bidirectional driving function of the power assembly 20, an additional driving motor for making the cleaning member 11 away from the ground is not needed, which reduces the manufacturing cost of the cleaning device.

[0072] In some embodiments, please refer to Figure 3The power assembly 20 includes a power unit 21 and a transmission unit 22, with the transmission unit 22 being drive-connected to both the power unit 21 and the turntable 13 of the cleaning assembly 10. Exemplarily, the power assembly also includes a support unit 23, which can be formed as a housing structure to provide a mounting base for related structures. The support unit 23 is detachably connected to the main body of the cleaning equipment. The power unit 21 is disposed on the support unit 23, and the transmission unit 22 is disposed within the support unit 23. A one-way locking member 30 is connected to both the support unit 23 and the cleaning assembly 10. The power unit 21 is drivenly connected to the cleaning assembly 10 via the transmission unit 22, enabling the cleaning assembly 10 to rotate relative to the support unit 23. The power unit 21 can be a motor, such as a brushed DC motor, a brushless DC motor, a stepper motor, or a servo motor.

[0073] For example, please refer to Figures 3-4 The cleaning assembly 10 includes a fastener 14, and the power assembly 20 and the cleaning assembly 10 are connected by the fastener 14 for easy assembly and disassembly. For example, the bottom of the rotating housing 12 of the cleaning assembly 10 has a second through hole 12b. Specifically, the rotating housing 12 may include a housing 122 and a base 123, with the housing 122 having the second through hole 12b. The fastener 14 passes through the second through hole 12b to connect the turntable 13 to the power assembly 20. Exemplarily, the transmission part 22 has a connecting shaft 2211, and the fastener 14 passes through the second through hole 12b and is fixed to the connecting shaft 2211. For example, the connecting shaft 2211 has an internal thread, and the fastener 14 is a bolt, with the fastener 14 threadedly connected to the connecting shaft 2211. By providing the fastener 14 to fix the turntable 13 to the power assembly 20, it is easy to install the rotating housing 12 and the turntable 13.

[0074] The transmission unit 22 can achieve transmission in any way, such as through gear transmission, belt transmission, chain transmission, etc. The speed ratio between the power unit 21 and the cleaning component 10 can be adjusted by setting the transmission unit 22. For example, the transmission unit 22 can be a speed-reducing transmission or a speed-increasing transmission.

[0075] For example, the transmission unit 22 includes a gear set for adjusting the speed difference between the cleaning component 10 and the power unit 21. The transmission unit 22 includes a first transmission wheel 221 with a connecting shaft 2211 protruding toward the rotating housing 12 for detachable connection with the cleaning component 10. When the cleaning component 10 malfunctions, such as being entangled in hair, the detachable connection between the cleaning component 10 and the transmission unit 22 facilitates hair removal compared to a direct connection between the cleaning component 10 and the power unit 21. For example, in cases where hair is difficult to remove, it is inconvenient to disassemble the power unit 21, but the transmission unit 22 can be disassembled, thereby reducing the possibility of the power unit 21 being entangled in hair and damaged as a result.

[0076] Exemplarily, the power part 21 rotates in a third direction to drive the cleaning part 11 to extend relative to the rotating shell 12, and the power part 21 rotates in a fourth direction to drive the cleaning part 11 to retract relative to the rotating shell 12. The third direction and the fourth direction are opposite.

[0077] In this way, when the power assembly 20 drives the cleaning assembly 10 to perform a cleaning operation, the power part 21 rotates in the third direction to drive the cleaning assembly 10 to rotate in the first direction R, so as to facilitate the collection of sundries to the suction port of the cleaning device. After the cleaning operation is completed, the power assembly 20 rotates in the fourth direction to drive the cleaning assembly 10 to rotate in the second direction S, so as to facilitate the lifting of the cleaning part 11 of the cleaning assembly 10 away from the ground. For example, when the cleaning part 11 is a side brush, the side brush can be conveniently stored. Without separately arranging an additional driving motor, the power part 21 driving the cleaning part 11 to perform a cleaning operation is reversely rotated to lift the cleaning part 11 away from the ground, which can reduce the production cost of the cleaning module 100.

[0078] According to different structures of the transmission part 22, the third direction can be the same as one of the first direction or the second direction. In some embodiments, the third direction is the same as the first direction, and in other embodiments, the third direction is the same as the second direction.

[0079] When the power part 21 drives the cleaning assembly 10 to rotate relative to the support part 23 in the first direction R, the one-way locking part 30 can rotate in the first direction R together with the cleaning assembly 10. When the cleaning operation is completed, the power part 21 drives the cleaning assembly 10 to rotate in the second direction S, and the one-way locking part 30 exerts resistance on the rotation of the cleaning assembly 10 to lock the cleaning assembly 10 again.

[0080] Exemplarily, please refer to Figure 3 The support part 23 includes a box body 231, a first protruding column 232, and a second protruding column 233. The power part 21 is arranged on the box body 231, and the transmission part 22 is arranged in the box body 231. The first protruding column 232 and the second protruding column 233 are both arranged on the box body 231, the second protruding column 233 surrounds the first protruding column 232, a containing cavity 23a is formed between the first protruding column 232 and the second protruding column 233, and at least part of the one-way locking part 30 is arranged in the containing cavity 23a.

[0081] For example, the one-way locking part 30 is a tension spring, at least part of the tension spring is arranged in the containing cavity 23a to provide a deformation space for the one-way locking part 30, which can reduce the possibility of external force interfering with the one-way locking part 30, and the second protruding column 233 can shield the one-way locking part 30 to beautify the appearance.

[0082] It can be understood that the radial dimension of the tension spring can be adaptively arranged according to the mounting position relationship with the first protruding column 232 and the second protruding column 233.

[0083] In some embodiments, referring to Figure 3 The one-way locking member 30 comprises a tensioning member 31, which is arranged on the power assembly 20 and fixedly connected with the cleaning assembly 10. When the power assembly 20 drives the cleaning assembly 10 to rotate in the first direction R, the tensioning member 31 can rotate along the power assembly 20. When the power assembly 20 drives the cleaning assembly 10 to rotate in the second direction S, the tensioning member 31 can tightly embrace the power assembly 20, so that the cleaning assembly 10 is locked.

[0084] Exemplarily, the tensioning member 31 is an integrally formed member. In this way, the structural strength of the tensioning member 31 can be improved, and the service life of the tensioning member 31 can be prolonged.

[0085] Exemplarily, the tensioning member 31 is a metal member, so as to improve the structural strength and reduce the possibility of damage of the tensioning member 31 under stress when locking the cleaning assembly 10.

[0086] Exemplarily, the tensioning member 31 is an elastic member, for example, a metal spring, so as to reduce the possibility of damage of the tensioning member 31 under stress when locking the cleaning assembly 10, while the structural strength can be improved.

[0087] Exemplarily, referring to Figure 3 The tensioning member 31 is, for example, a tensioning spring. The tensioning member 31 is circumscribed on the first protruding column 232, the initial inner diameter of the tensioning member 31 is adapted to the outer diameter of the first protruding column 232, and the rotation direction of the tensioning member 31 is the same as the second direction S. The tensioning member 31 is, for example, a tensioning spring, and the rotation direction of the tensioning member 31 refers to the spiral direction of the tensioning spring. In the locked state, the tensioning member 31 is sleeved on the first protruding column 232 and tightly embraces the outer wall of the first protruding column 232. In this way, when the power assembly 20 drives the cleaning assembly 10 to rotate towards the second direction S, the tensioning member 31 applies a locking force to the first protruding column 232; the greater the angle at which the power assembly 20 drives the cleaning assembly 10 to rotate towards the second direction S, the greater the locking force applied by the tensioning member 31 to the first protruding column 232.

[0088] In another embodiment not shown, the tensioning member 31 is inscribed in the second protruding column 233, the initial outer diameter of the tensioning member 31 is adapted to the inner diameter of the second protruding column 233, and the rotation direction of the tensioning member 31 is the same as the first direction R.

[0089] For example, the tensioning member 31 is a tensioning spring. In the locked state, the tensioning member 31 is sleeved on the outer wall of the first protruding column 232 and abuts against the inner wall of the second protruding column 233. In this way, when the power assembly 20 drives the cleaning assembly 10 to rotate towards the second direction S, the tensioning member 31 applies a locking force to the second protruding column 233, so that the cleaning assembly 10 cannot continue to rotate; the greater the angle at which the power assembly 20 drives the cleaning assembly 10 to rotate towards the second direction S, the greater the locking force applied by the tensioning member 31 to the second protruding column 233.

[0090] For example, referring to Figures 3-5 , the tensioning member 31 is a tensioning spring, which includes a spring 311 and an arm 312. The spring 311 is wound around the power assembly 20. The arm 312 is connected to the end of the spring 311, and the arm 312 is fixedly connected to the cleaning assembly 10. The arm 312 is fixed to the cleaning assembly 10, for example, can be threaded through the hole of the rotating shell 12, or hung on the hole or hook of the rotating shell 12, or clamped on the seat of the rotating shell 12.

[0091] For example, the rotation direction of the spring 311 is the same as the second direction S. The spring 311 is wound around the power assembly 20, such as the outer wall of the first protruding column 232, so that when the cleaning assembly 10 rotates towards the second direction S, the spring 311 is tightly wound around the support part 23, so as to lock the rotation of the cleaning assembly 10 towards the second direction S. When the cleaning assembly 10 rotates towards the first direction R, the end of the spring 311 connected to the cleaning assembly 10 is driven to rotate towards the first direction R, and the spring 311 loosens the locking of the cleaning assembly 10, that is, the cleaning assembly 10 rotates towards the second direction S, and the tensioning member 31 does not have a locking effect.

[0092] When the cleaning work is finished and the cleaning member 11 needs to be lifted away from the ground, the power assembly 20 can drive the cleaning assembly 10 to rotate along the second direction S. The spring 311 is gradually increased in the tightening force on the first protruding column 232 under the driving of the cleaning assembly 10, and returns to the locking state again, which locks the rotation of the cleaning assembly 10 along the second direction S.

[0093] For example, the spring 311 and the arm 312 are integrally formed, which is convenient for production and can improve the structural strength of the tensioning member 31.

[0094] In some embodiments, referring to Figures 3-5 , the rotating shell 12 includes a shell 122 and a seat 123. The rotating disc 13 is arranged in the shell 122, and the seat 123 is arranged on the shell 122. The end of the tensioning member 31 is fixed to the seat 123. The seat 123 can support and limit the arm 312. The shell 122 and the seat 123 can be fixed by clamping, screwing, or the like, or can be fixed by welding or gluing. For example, the shell 122 includes a first shell 1221 and a second shell 1222 which are detachably connected. The first through hole 12a is formed at the connection between the first shell 1221 and the second shell 1222, so that the cleaning member 11 can be conveniently disassembled. The first shell 1221 and the second shell 1222 can be fixed by clamping, screwing, or the like, and the second shell 1222 can rotate together with the first shell 1221.

[0095] Exemplarily, the support portion 23 comprises a third protruding column 234, which is arranged on the box 231, the first protruding column 232 is arranged outside the third protruding column 234, and the mounting cavity 23b is formed between the first protruding column 232 and the third protruding column 234, and at least part of the rotating shell 12 is located in the mounting cavity 23b. In this way, the sealing property of the rotating shell 12 can be improved, and the possibility of garbage entering the rotary disc 1 through the upper end of the rotating shell 12 can be reduced.

[0096] In some embodiments, referring to Figure 6 and Figure 8 , the rotary disc 13 comprises a disc body 131 and a moving groove 131a formed on the disc body 131, and one end of the cleaning member 11 can move in the moving groove 131a. For example, referring to Figure 5 , the cleaning member 11 is formed with a connecting column 112, which is connected to the moving groove 131a, so that the rotary disc 13 drives the cleaning member 11 to move together through the connecting column 112. The connecting column 112 can be in a cylindrical shape, so as to reduce the contact area with the disc body 131 when moving in the moving groove 131a, thereby reducing the moving resistance.

[0097] When the rotary disc 13 rotates in the first direction R, the cleaning member 11 can be driven to extend relative to the rotating shell 12; when the rotary disc 13 rotates in the second direction S, the cleaning member 11 can be driven to retract relative to the rotating shell 12.

[0098] By arranging the moving groove 131a, the cleaning member 11 can be driven by the rotating shell 12 to extend or retract along the track of the moving groove 131a. For example, when cleaning operation is needed, the rotating shell 12 can drive the cleaning member 11 to extend relative to the rotating shell 12 through the moving groove 131a, the cleaning member 11 is lowered relative to the ground, so that the cleaning member 11 contacts the ground; after the cleaning operation is completed, the power portion 21 of the operation power assembly 20 is switched to drive in the opposite direction, and the rotating shell 12 can drive the cleaning member 11 to retract relative to the rotating shell 12 through the moving groove 131a, the cleaning member 11 is raised relative to the ground, so that the cleaning member 11 is lifted off the ground.

[0099] Exemplarily, the extension direction of the moving groove 131a is not limited, for example, the two ends of the moving groove 131a are respectively located at different distances from the rotation axis of the rotary disc 13 in the radial direction of the rotary disc 13, and the two ends of the moving groove 131a are connected by a straight line or a smooth curve.

[0100] Exemplarily, the number of the cleaning member 11 and the moving groove 131a is the same, and both are multiple, for example, both are two, three or four.

[0101] Exemplarily, one of the rotating shell 12 and the cleaning member 11 comprises a guide groove, and the other of the rotating shell 12 and the cleaning member 11 comprises a guide rail, the guide rail and the guide groove are matched to enable the cleaning member 11 to move relative to the rotating shell 12. By arranging the guide rail and the guide groove, the cleaning member 11 can move relative to the rotating shell 12, the stability of movement of the cleaning member 11 is improved, and the cleaning range of the cleaning member 11 is expanded.

[0102] In some embodiments, referring to Figures 5-7 , a first cleaning module is provided, the moving groove 131a is an arc-shaped groove, the extending direction of the arc-shaped groove deviates from the rotation axis of the rotating shell 12, and the extending directions of the guide rail and the guide groove are towards the rotation axis of the rotating shell 12.

[0103] Exemplarily, the cleaning member 11 comprises a first guide rail 111, and the rotating shell 12 comprises a first guide groove 12c. The extending directions of the first guide groove 12c and the first guide rail 111 are towards the rotation axis of the rotating shell 12.

[0104] In some embodiments, referring to Figures 8-11 , a second cleaning module is provided, the moving groove 131a is a straight groove, the extending direction of the straight groove is towards the rotation axis of the rotating shell 12, and the extending directions of the guide rail and the guide groove deviate from the rotation axis of the rotating shell 12.

[0105] Exemplarily, the cleaning member 11 comprises a second guide groove 11a, and the rotating shell 12 comprises a second guide rail 124. The extending directions of the second guide groove 11a and the second guide rail 124 deviate from the rotation axis of the rotating shell 12. In this way, the possibility of hair winding on the cleaning member 11 can be reduced, and the designable length of the second guide rail 111 and the second guide groove 12c can be increased, so as to facilitate the retraction of the cleaning member 11 relative to the rotating shell 12.

[0106] Exemplarily, the moving groove 131a penetrates through the outer circumferential side of the disc body 131; the rotating shell 12 has a first limiting member 121, and the disc body 131 has a second limiting member 1311, the second limiting member 1311 can abut against the first limiting member 121 to enable the rotating shell 12 to move or stop with the rotating disc 13.

[0107] When the second limiting member 1311 abuts against the first limiting member 121, the rotating shell 12 can move or stop with the rotating disc 13, and when the second limiting member 1311 does not abut against the first limiting member 121, the disc body 131 and the rotating shell 12 can rotate relative to each other, so as to facilitate the retraction of the cleaning member 11 relative to the rotating shell 12.
