Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, in particular to a cleaning device and a cleaning equipment. BACKGROUND

[0002] When the cleaning equipment cleans a surface to be cleaned, it is usually necessary to control the movement of the side brush of the cleaning device, for example, to control the outward swing of the side brush to the surface to be cleaned, and to control the rotation and descent of the side brush to the surface to be cleaned, to contact the surface to be cleaned, and to control the lifting of the side brush from the surface to be cleaned after the cleaning is completed, and to swing back into the cleaning device.

[0003] In the related art, the cleaning equipment generally drives the rotation of the side brush by one motor and drives the swing of the side brush by another motor. Since the driving forces for rotation and swing are both high, a driving motor with a large output power is required to drive, thus causing the two motors to occupy a large space, and the two motors also need to be arranged with corresponding transmission mechanisms to the cleaning assembly to respectively drive the rotation and swing of the cleaning assembly, further occupying the space, which is not conducive to improving the integration of the cleaning device. Utility model content

[0021] The inner retracted position and the lifting position are arranged close to the body of the cleaning device, and the outer swinging position and the lowering position are arranged away from the body of the cleaning device.

[0022] The driving mechanism is used to drive the cleaning assembly to move between the outer swinging position and the inner retracted position, and synchronously drive the cleaning assembly to move between the lifting position and the lowering position.

[0023] In an embodiment, a tangential mechanism is connected with the driving mechanism.

[0024] The driving mechanism comprises a driving member and at least two sets of transmission groups, the transmission groups are respectively connected to the driving member and the cleaning assembly, and the two sets of transmission groups are configured to output driving force in opposite directions.

[0042] The second aspect of the present application provides a cleaning device, comprising the cleaning device as described above.

[0043] The technical scheme provided by the present application can include the following beneficial effects: the cleaning device provided by the present application is driven by the driving mechanism and the rotating swing component of the cleaning assembly, and the driving mechanism drives the rotating swing component to rotate in the first preset direction. A damping member is arranged on the rotating swing component, and the damping member and the rotating swing component rotate relative to each other in the first preset direction to generate a damping force. Since the driving mechanism drives the rotating swing component, the damping force acts on the rotating swing component, which is equivalent to acting on the driving mechanism, thereby hindering the rotation of the driving mechanism. The reaction force of the driving mechanism is used as the swing force, thereby driving the cleaning assembly to swing in the second preset direction. Therefore, the driving mechanism of the present embodiment can realize the rotation and swing of the cleaning assembly by outputting a single driving force, without the need to separately arrange two large motors for driving the cleaning assembly to rotate and for driving the cleaning assembly to swing, thereby reducing the space occupation. In addition, the rotating transmission mechanism and the swing transmission mechanism do not need to be arranged corresponding to the two large motors, further reducing the space occupation, simplifying the structure, improving the space utilization, and improving the integration of the cleaning device.

The driving mechanism includes a driving member and at least two sets of transmission groups, and the transmission groups are respectively connected to the driving member and the cleaning assembly. The directions of the driving forces output by the two sets of transmission groups are opposite. The tangential mechanism is used to cut off the connection between the driving member and one of the transmission groups, and to connect the driving member to the other transmission group. By arranging the tangential mechanism and the at least two sets of transmission groups with opposite directions of the driving force output, the power output by the driving member can be switched between the two sets of transmission groups, so that when the driving member rotates in one direction, the cleaning assembly can also be controlled to rotate forward or reverse in the first preset direction. Since the damping force of the damping member is equivalent to acting on the driving member, it is not affected by the switching of the power direction of the transmission group and is directly controlled by the driving direction of the driving member. Therefore, the driving member outputting a single driving force can be used to independently control the swing and rotation of the cleaning assembly, thereby optimizing the control mode of the cleaning assembly and enhancing the functionality of the cleaning device, which is conducive to the intelligent design of the cleaning device.

[0059] In view of the above problems, the embodiments of the present application provide a transmission mechanism which can optimize the control mode, improve compatibility and facilitate the functional expansion of the cleaning equipment.

[0060] The technical solutions of the embodiments of the present application will be described in detail below with reference to the drawings.

[0061] Reference is made to Figure 1The embodiment provides a cleaning device 100, which comprises a cleaning assembly 10 and a driving mechanism 20. The cleaning assembly 10 comprises a rotating swing assembly 11 and a damping piece 12 arranged in the circumferential direction of the rotating swing assembly 11 in a first preset direction; the driving mechanism 20 is in transmission connection with the rotating swing assembly 11, and is used for driving the rotating swing assembly 11 to rotate in the first preset direction and providing a swing force opposite to the damping force of the damping piece 12, so as to drive the cleaning assembly 10 to swing in a second preset direction.

[0062] The driving mechanism 20 is configured to rotate in a forward direction or a reverse direction, for example, rotate in a clockwise direction or rotate in an anticlockwise direction, so as to output a forward driving force or a reverse driving force.

[0063] The rotating swing assembly 11 is in transmission connection with the driving mechanism 20 and is driven by the driving mechanism 20 to rotate in the first preset direction, so as to rotate relative to the damping piece 12 arranged in the circumferential direction. The damping piece 12 generates a damping force opposite to the rotating direction of the rotating swing assembly 11, and the damping force acts on the rotating swing assembly 11. Since the rotating swing assembly 11 is driven by the driving mechanism 20, the damping force is equivalent to acting on the driving mechanism 20. When the driving mechanism 20 rotates, the damping force from the damping piece 12 is generated, and a swing force opposite to the damping force is generated, so as to force the cleaning assembly 10 to swing in the second preset direction.

[0064] For the convenience of understanding, for example, the forward rotation of the driving mechanism 20 can be in the clockwise direction, the first preset direction can be in the clockwise direction, and the second preset direction can be in the tangential direction opposite to the clockwise direction. When the driving mechanism 20 rotates forward, the rotating swing assembly 11 rotates synchronously in the clockwise direction, the damping piece 12 provides the damping force in the tangential direction opposite to the anticlockwise direction of the rotating swing assembly 11, the damping force acts on the rotating swing assembly 11, and is equivalent to acting on the driving mechanism 20 driving the rotating swing assembly 11 to rotate. Since the driving mechanism 20 rotates in the clockwise direction, the damping force in the tangential direction opposite to the anticlockwise direction is equivalent to being generated, and a reaction force opposite to the damping force is generated, the reaction force acts on the damping piece 12, a swing force driving the cleaning assembly 10 is formed, and the cleaning assembly 10 swings in the second preset direction.

[0065] It should be noted that when the driving mechanism 20 rotates forward, the first preset direction can also be in the anticlockwise direction, and when the driving mechanism 20 reverses, the first preset direction can also be in the clockwise direction or the anticlockwise direction, which is not limited in the embodiment.

[0066] The embodiment sets the damping member 12 in the rotation circumferential direction of the rotary swing assembly 11, drives the cleaning assembly 10 to swing by using the swing force opposite to the damping force, and enables the driving mechanism 20 to simultaneously drive the cleaning assembly 10 to rotate and swing, so that two large motors respectively used for driving the cleaning assembly 10 to rotate and for driving the cleaning assembly 10 to swing are not needed, and the rotary transmission mechanism and the swing transmission mechanism respectively corresponding to the two large motors are not needed to be arranged, thereby reducing the space occupation, improving the integration of the cleaning device 100, simplifying the transmission control mechanism of the cleaning device 100, and being beneficial to improving the space utilization of the cleaning equipment 1000.

[0067] Referring to Figure 1 In one of the embodiments, the cleaning assembly 10 further comprises a cleaning member 13; the rotary swing assembly 11 is in transmission connection with the driving mechanism 20 and the cleaning member 13 respectively; when the rotary swing assembly 11 is driven by the driving mechanism 20, the cleaning member 13 is driven to rotate in the first preset direction, and is also synchronously driven to lift in the third preset direction.

[0068] The cleaning member 13 can be an edge brush, an edge sweeper, a cleaning cloth or an edge mop, and is used to contact and clean the surface to be cleaned.

[0069] The cleaning member 13 can have an axial rotation center, the first preset direction can be clockwise or counterclockwise rotation of the cleaning member 13 about the rotation center, and the second preset direction can be lifting or lowering movement of the cleaning member 13 along the axial direction. The cleaning member 13 can be separated from the surface to be cleaned when the cleaning member 13 is lifted, and can contact the surface to be cleaned when the cleaning member 13 is lowered. The surface to be cleaned can be a ground, but is not limited to this.

[0070] The rotary swing assembly 11 of the embodiment is driven by the driving mechanism 20, and when the rotary swing assembly 11 rotates in the first preset direction, the cleaning member 13 is driven to rotate in the first preset direction, and the lifting and lowering of the cleaning member 13 in the third preset direction are controlled by the rotation of the rotary swing assembly 11 in the first preset direction. The driving mechanism 20 drives the cleaning member 13 to realize the functions of swing, rotation and lifting and lowering, avoids setting multiple high-power motors for control, thereby reducing the space occupation, improving the space utilization, simplifying the structural arrangement of the cleaning device 100, and improving the integration of the cleaning device 100.

[0071] To realize the lifting and lowering of the cleaning member 13 in the third preset direction, referring to Figure 1 , Figure 2 and Figure 4In one of the embodiments, the rotating and swinging assembly 11 comprises a screw rod 111 and a sleeve 112 threadedly connected, the screw rod 111 is connected with the driving mechanism 20; when the screw rod 111 is driven by the driving force of the driving mechanism 20 to rotate in the first preset direction, the sleeve 112 rotates synchronously with the screw rod 111 or rotates oppositely with the screw rod 111 to ascend and descend in the third preset direction, so as to drive the cleaning member 13 to ascend and descend in the third preset direction.

[0072] In the embodiment, the screw rod 111 can be arranged to be rotatable in the first preset direction and fixed in the third preset direction; the sleeve 112 can be arranged to be rotatable in the first preset direction and slidable in the third preset direction.

[0073] In the embodiment, the screw rod 111 can be provided with external threads, and the sleeve 112 can be provided with internal threads, the sleeve 112 is sleeved on the outer circumferential wall of the screw rod 111, and the connection is achieved through the thread connection of the external threads and the internal threads.

[0074] In the embodiment, the screw rod 111 is connected with the driving mechanism 20, and is driven by the driving force of the driving mechanism 20 to rotate in the first preset direction; when the sleeve 112 rotates oppositely with the screw rod 111, the sleeve 112 moves up and down in the third preset direction perpendicular to the first preset direction, and then drives the cleaning member 13 to ascend and descend in the third preset direction through the sleeve 112, so as to realize the cleaning function of the cleaning member 13.

[0075] It can be understood that when the sleeve 112 rotates oppositely with the screw rod 111 to a preset limit position or a thread connection limit position, the sleeve 112 and the screw rod 111 no longer rotate oppositely, the sleeve 112 rotates synchronously with the screw rod 111 in the first preset direction, and then the cleaning member 13 rotates in the first preset direction and is fixed in the third preset direction, so that the cleaning member 13 can continuously clean the surface to be cleaned or keep separated from the surface to be cleaned, and obstacles are avoided.

[0076] Referring to Figure 4 In one of the embodiments, the rotating and swinging assembly 11 further comprises a bearing 113; the sleeve 112 is arranged in the axial through hole of the bearing 113, and is limited in the first preset direction with the bearing 113 and is arranged slidably in the third preset direction relative to the bearing 113; the damping member 12 abuts against the rotating circumferential direction of the bearing 113 in the first preset direction; when the bearing 113 rotates in the first preset direction, the damping force of the damping member 12 is received, and the damping force is transmitted to the sleeve 112 arranged in the bearing 113, so that the sleeve 112 ascends and descends in the third preset direction relative to the screw rod 111 and the bearing 113; and when the bearing 113 rotates in the first preset direction, the damping force of the damping member 12 is received, so that the cleaning assembly 10 receives the reaction force of the damping force of the driving mechanism 20, and then swings in the second preset direction.

[0077] The bearing 113 and the sleeve 112 can be provided with a clamping structure, for example, a groove is arranged on the inner circumferential wall of the bearing 113, and a protrusion is arranged on the outer circumferential wall of the sleeve 112, and the groove and the protrusion are fixedly connected through cooperation.

[0078] In the embodiment, the groove of the bearing 113 can be arranged along the third preset direction, and the groove is provided with a notch at both ends along the third preset direction, the protrusion of the sleeve 112 is embedded in the groove, and can move away from the notch along the third preset direction, and at least partially separate from the groove. The number of the groove and the protrusion is not limited, for example, one pair, two pairs or three pairs, etc.

[0079] Referring to Figure 1 and Figure 4 In one of the embodiments, the cleaning assembly 10 further comprises a mounting member 14, which is used to accommodate the end of the cleaning member 13 and drive the cleaning member 13 to rotate. The mounting member 14 is fixedly connected with the bearing 113, and when the bearing 113 rotates along the first preset direction, the mounting member 14 rotates synchronously, thereby driving the cleaning member 13 to rotate synchronously.

[0080] The damping member 12 can abut against the outer circumferential wall of the bearing 113 and be arranged along the rotation circumferential direction of the first preset direction. The number of the damping member 12 can be 1, 2, 3 or more, which is not limited in the embodiment.

[0081] On the one hand, when the driving mechanism 20 drives the lead screw 111 to rotate along the first preset direction, the lead screw 111 drives the sleeve 112 to rotate along the first preset direction, thereby driving the bearing 113 to rotate along the first preset direction relative to the damping member 12 and being subjected to the damping force of the damping member 12, so that the bearing 113 and the lead screw 111 rotate relatively. Since the bearing 113 and the sleeve 112 are limited in the first preset direction, the sleeve 112 also rotates relatively with the lead screw 111. Since the sleeve 112 can ascend and descend along the third preset direction relative to the bearing 113, when the sleeve 112 rotates relatively with the lead screw 111, the sleeve 112 can ascend and descend along the groove arranged on the bearing 113 along the third preset direction.

[0082] On the other hand, when the bearing 113 rotates along the first preset direction relative to the damping member 12 and is subjected to the damping force of the damping member 12, since the driving force of the rotary swing assembly 11 comes from the driving mechanism 20, the damping force is equivalent to the force acting on the driving mechanism 20, and the driving mechanism 20 generates a counterforce to the rotary swing assembly 11, thereby making the cleaning assembly 10 swing.

[0083] In one of the embodiments, the damping member 12 comprises a ball and a rolling groove, the ball is embedded in the rolling groove, and abuts against the rotary swing assembly.

[0084] The opening of the rolling groove can abut against the rotating swing assembly 11, for example, the outer circumferential wall of the bearing 113 in combination with the above embodiment, so that the rolling groove is closed. When the bearing 113 rotates in the first preset direction, the rolling ball in the rolling groove is driven to rotate, and the rolling ball rotates relative to the bearing 113, so that the bearing 113 is subjected to a damping force. It can be understood that when the damping force is less than the driving force obtained by the bearing 113, the bearing 113 continues to rotate, and when the damping force in any direction is greater than the driving force obtained by the bearing 113, the bearing 113 cannot rotate in the direction, forming a one-way bearing.

[0085] It can be understood that when the groove depth of the rolling groove is equal to the diameter of the rolling ball, the rolling ball can roll in the forward direction or the reverse direction and abut against the groove bottom and the bearing 113 respectively, thereby providing a damping force. When the groove depth of at least one position of the rolling groove is less than the diameter of the rolling ball, the movement of the rolling ball towards the position is subjected to greater resistance, thereby the rotating speed is smaller or the rolling ball cannot rotate. When the rotating speed is small, the rotating speed of the bearing 113 is also small, thereby the rotating speed of the cleaning piece 13 is also small. When the rolling ball cannot rotate, the bearing 113 also cannot rotate, thereby the cleaning piece 13 is stopped. Therefore, the rolling groove of the embodiment can be adaptively designed according to the functional requirements, which is not specifically limited in the embodiment.

[0086] In one of the embodiments, the rolling ball and the rolling groove can be one or two, and can be symmetrically arranged. The rolling ball and the rolling groove can also be three, and form an equilateral triangle on the outer circumferential wall of the bearing 113, which is beneficial to uniformly stress the outer circumferential wall of the bearing 113.

[0087] In order to realize the rotation of the cleaning piece 13 in different directions, in one of the embodiments, the rolling ball can roll in the rolling groove in the forward direction or the reverse direction, and the rolling ball is a metal rolling ball.

[0088] The groove depth of the rolling groove can be kept the same, so that the speed of the rolling ball rolling in the rolling groove in the forward direction or the reverse direction can be the same, thereby the damping force provided by the rolling ball rolling in the forward direction or the reverse direction is the same. However, the groove depth of the rolling groove can also have a certain inclination, so that the speed is different, thereby the damping force provided by the rolling ball rolling in the forward direction or the reverse direction is different.

[0089] In one of the embodiments, the groove depth of the rolling groove in the forward rotation direction of the first preset direction is greater than the groove depth in the reverse rotation direction of the first preset direction.

[0090] The rolling groove can include a first groove body and a second groove body, the second groove body and the first groove body are arranged in the forward rotation direction of the first preset direction in sequence, and the depth of the first groove body is greater than the depth of the second groove body. That is, when the bearing 113 rotates in the first preset direction, the rolling ball is driven to roll in the first preset direction, thereby entering the first groove body. When the bearing 113 rotates in the first preset direction, the rolling ball is driven to roll in the first preset direction, thereby entering the second groove body.

[0091] For example, when the rotating swing assembly 11 rotates in the first preset direction, the bearing 113 drives the cleaning member 13 to rotate in the first preset direction, and the rolling ball rolls relative to the bearing 113, so that the damping force of the rolling ball is transmitted to the driving mechanism 20, so that the driving mechanism 20 drives the cleaning assembly 10 to swing in the second preset direction, and the sleeve 112 in the bearing 113 is also subjected to the damping force and rotates relative to the screw rod 111, and descends in the third preset direction. When the rotating swing assembly 11 reverses in the first preset direction, the bearing 113 drives the cleaning member 13 to reverse, and the sleeve 112 is subjected to the damping force and rises in the third preset direction. Since the groove depth of the rolling groove in the forward rotating direction of the first preset direction is greater than the groove depth in the reverse rotating direction of the first preset direction, that is, the depth of the second groove body is less than that of the first groove body, when the rolling ball enters the second groove body, the abutting force of the rolling ball against the bearing 113 is greater, so that the damping force provided is greater, so that the rotating speed of the bearing 113 is slower, and the speed of the reverse rotation of the cleaning member 13 is controlled to be slower.

[0092] The embodiment sets the depth of the rolling groove, so that the bearing 113 can rotate in the first preset direction or reverse, so that the rotating speed of the bearing 113 in the forward rotating direction and the reverse rotating direction is different, so that the speed of the cleaning member 13 in the forward rotating direction or the reverse rotating direction can be different, the function of the cleaning device 100 is enriched, and the intelligentization of the cleaning device 100 is improved.

[0093] Since the rolling ball rotates and rubs against the rolling groove and the bearing 113, the embodiment sets the rolling ball as a metal rolling ball, which has high strength and service life, and avoids early wear and tear to affect the use of the cleaning device 100.

[0094] In one of the embodiments, the cleaning assembly 10 has a preset outer swing position and an inner retraction position in the second preset direction, and has a preset lifting position and a lowering position in the third preset direction; the inner retraction position and the lifting position are arranged close to the body of the cleaning equipment 1000, and the outer swing position and the lowering position are arranged away from the body of the cleaning equipment 1000; the driving mechanism 20 is used to drive the cleaning assembly 10 to move between the outer swing position and the inner retraction position, and synchronously drive the cleaning assembly 10 to move between the lifting position and the lowering position.

[0095] Referring to Figure 1 In one of the embodiments, the cleaning device 100 further comprises a tangential mechanism 30, and the tangential mechanism 30 is connected with the driving mechanism 20; the driving mechanism 20 comprises a driving member 21 and at least two sets of transmission groups 22, the transmission groups 22 are respectively connected to the driving member 21 and the cleaning assembly 10, and the two sets of transmission groups 22 are configured to have opposite directions of output driving force; the tangential mechanism 30 is used to cut off the connection between the driving member 21 and one of the transmission groups 22, and connect the driving member 21 to the other transmission group 22.

[0096] The driving member 21 is configured to rotate in clockwise or counterclockwise direction. For convenience, the clockwise direction is defined as positive direction, and the counterclockwise direction is defined as negative direction. For example, when the driving member 21 rotates in positive direction, the positive driving force is output to the transmission set 22, and then transmitted to the cleaning assembly 10 by the transmission set 22, so as to control the cleaning assembly 10.

[0097] Since the transmission set 22 is provided with at least two sets, and the two sets of transmission set 22 are configured to output driving force in opposite directions, when the tangential mechanism 30 cuts off the connection between the driving member 21 and one of the transmission set 22, and connects the driving member 21 to the other transmission set 22, the driving force output to the cleaning assembly 10 will be changed, so as to change the rotation of the cleaning assembly 10 in the first preset direction.

[0098] The embodiment changes the direction of the driving force output to the cleaning assembly 10 by the driving mechanism 20 through the tangential mechanism 30, so as to change the rotation of the cleaning assembly 10 in the first preset direction, and further control the working state of the cleaning assembly 10.

[0099] For example, in combination with the screw rod 111 and the sleeve 112 described in the above embodiment, when the screw rod 111 rotates in the negative direction of the first preset direction, the direction of the damping force acting on the sleeve 112 will also be changed, so as to make the sleeve 112 rise or fall in the negative direction of the third preset direction.

[0100] For example, in combination with the bearing 113 described in the above embodiment, when the sleeve 112 rotates in the negative direction of the first preset direction, the bearing 113 rotates in the negative direction of the first preset direction along with the sleeve 112, so as to change the direction of the damping force. However, the change of the damping force is relative to the bearing 113 and the sleeve 112. For the cleaning device 100, since the driving member 21 is the driving force input end of the driving mechanism 20, the rotation direction of the driving member 21 does not change, so as to make the damping force in the whole transmission system still used to hinder the rotation, that is, the direction of the reaction force corresponding to the damping force of the driving member 21 does not change, so as to drive the cleaning assembly 10 to swing in the second preset direction.

[0101] Referring to Figure 1 and Figure 6 In one embodiment, the transmission set 22 includes a first transmission set 23 and a second transmission set 24; the first transmission set 23 and the second transmission set 24 are respectively connected with the cleaning assembly 10, and are configured to output driving force to the cleaning assembly 10, and the directions of the driving force output by the first transmission set 23 and the second transmission set 24 are opposite.

[0102] The first transmission group 23 and the second transmission group 24 can be arranged towards the cleaning assembly 10 from the driving member 21, and the first transmission group 23 and the second transmission group 24 can have partially shared transmission components, but can also be arranged independently, and the embodiment is not limited specifically.

[0103] To facilitate the description of the above embodiment, a working condition of the cleaning device 100 is described below.

[0104] The driving member 21 rotates forward, and is in transmission connection with the first transmission group 23. The first transmission group 23 does not change the output direction of the driving force of the driving member 21, so that the lead screw 111 rotates forward along the first preset direction, the sleeve 112 and the bearing 113 are driven to rotate forward by the lead screw 111, and the bearing 113 can drive the cleaning member 13 to rotate forward. The damping force of the damping member 12 acts on the bearing 113, and then acts on the driving member 21. The driving member 21 reacts to the damping force to form a swing force, so that the cleaning assembly 10 swings from the preset retracted position to the outer swing position. In addition, the damping force also acts on the sleeve 112 through the bearing 113, so that the sleeve 112 rotates relative to the lead screw 111, and the sleeve 112 descends along the third preset direction and drives the cleaning member 13 to descend. Thus, the cleaning member 13 rotates forward, moves from the retracted position to the outer swing position, and descends to the surface to be cleaned.

[0105] When the above working condition needs to be changed, for example, when the cleaning device 100 needs to avoid obstacles, interrupt cleaning, or avoid part of the surface to be cleaned, the tangential mechanism 30 disconnects the driving member 21 from the first transmission group 23, and connects the driving member 21 to the second transmission group 24 whose output driving force is opposite. The driving force output by the driving member 21 is forward, and the second transmission group 24 changes the direction of the driving force to reverse, so that the lead screw 111 reverses along the first preset direction, and then the sleeve 112 drives the cleaning member 13 to ascend. However, the driving member 21 itself still rotates forward, and the swing force direction of the damping force does not change, so the cleaning assembly 10 does not swing along the second preset direction, and the cleaning member 13 remains in the outer swing position.

[0106] It can be understood that when the driving member 21 reverses, the cleaning assembly 10 will move from the outer swing position to the retracted position. When the driving member 21 reverses and is combined with the first transmission group 23, the cleaning member 13 will also reverse and ascend. When the driving member 21 reverses and is combined with the second transmission group 24, the cleaning member 13 will also rotate forward and descend. However, the above examples are only for illustration and are not limited to the embodiment.

[0107] The embodiment provides multiple working modes by arranging the tangential mechanism 30 to realize multiple combination control modes of the cleaning assembly 10, which not only improves the integration of the cleaning device 100, reduces the space occupation, but also improves the functional richness of the cleaning device 100.

[0108] Referring toFigure 5 In one of the embodiments, the driving member 21 comprises a clutch member 211 fixed to the driving member 21 and used for transmission connection with the transmission set 22; the tangential mechanism 30 is connected with the driving member 21 and used for controlling the clutch member 211 to engage or disengage with the transmission set 22.

[0109] The clutch member 211 can be fixed to the driving member 21 and follow the driving member 21 to rotate forward or reverse, and also follow the driving member 21 to ascend or descend.

[0110] Since the output directions of the two sets of transmission sets 22 are opposite, the clutch member 211 is combined with different transmission sets 22, the direction of the driving force output to the cleaning assembly 10 can be controlled, and the same direction of power output can be realized when the driving member 21 rotates forward and reverse, which increases the control scheme, optimizes the control mode, improves the compatibility, and is beneficial to the function expansion of the cleaning equipment 1000.

[0111] Referring to Figure 5 In one of the embodiments, the first transmission set 23 comprises a first transmission member 231, and the second transmission set 24 comprises a second transmission member 241; the first transmission member 231 and the second transmission member 241 are respectively connected with the driving member 21, and the tangential mechanism 30 is used for making the clutch member 211 disengage or engage with the first transmission member 231, and making the clutch member 211 disengage or engage with the second transmission member 241.

[0112] The first transmission member 231 and the second transmission member 241 can be arranged on opposite sides of the clutch member 211, and the driving member 21 can relatively rotate and move relative to the first transmission member 231 and the second transmission member 241. The movement of the driving member 21 is controlled by the tangential mechanism 30, so as to synchronously move the clutch member 211, and then realize the connection or disconnection with the first transmission member 231 and the second transmission member 241.

[0113] In order to realize the connection of the clutch member 211 with the first transmission member 231 and the second transmission member 241, for example, in one of the embodiments, the clutch member 211 is provided with a clutch portion on both sides; the first transmission member 231 and the second transmission member 241 are respectively provided with a first matching portion and a second matching portion on the side facing the clutch member 211; by engaging the clutch portion with the first matching portion or the second matching portion, the clutch member 211 can drive the first transmission member 231 or the second transmission member 241 to rotate.

[0114] For example, the upper end face and the lower end face of the clutch member 211 are respectively provided with a clutch part, the first transmission member 231 can be arranged on the upper side of the clutch member 211, and the lower end face of the first transmission member 231 is provided with a first matching part; the second transmission member 241 can be arranged on the lower side of the clutch member 211, and the upper end face of the second transmission member 241 is provided with a second matching part, so as to realize the matching with the first transmission member 231 when the clutch member 211 moves upward and the matching with the second transmission member 241 when the clutch member 211 moves downward.

[0115] In one of the embodiments, the clutch part, the first matching part and the second matching part are all provided with a sawtooth structure, which includes a clamping protrusion and a clamping recess; when the sawtooth structure of the clutch part matches with the sawtooth structure of the first matching part or the second matching part, the clamping protrusion arranged on the clutch part is embedded in the clamping recess of the first matching part or the second matching part, and the clamping protrusion arranged on the first matching part or the second matching part is embedded in the clamping recess of the clutch part, so that the sawtooth structures are engaged, thereby enhancing the reliability of the fixed connection and improving the transmission effect.

[0116] Referring to Figure 5 In one of the embodiments, the driving member 21 includes a driving shaft 210, which is arranged to be rotatable in the circumferential direction and movable in the axial direction; the driving shaft 210 is sequentially arranged in the first transmission member 231, the clutch member 211 and the second transmission member 241, and the first transmission member 231 and the second transmission member 241 are fixed in the axial direction of the driving member 21.

[0117] The rotating shaft is arranged to be movable in the axial direction and rotatable in the circumferential direction with the axial direction as the center; for example, the rotating shaft is arranged to be movable upward or downward in the axial direction and rotatable clockwise or counterclockwise in the circumferential direction.

[0118] The driving shaft 210 is arranged to be slidably connected with the first transmission member 231 and the second transmission member 241 in the axial direction and the circumferential direction, so that the driving shaft 210 can rotate and move relative to the first transmission member 231 and the second transmission member 241.

[0119] The driving shaft 210 is fixedly connected with the clutch member 211; when the clutch member 211 moves in the axial direction to a position close to the first transmission member 231 or the second transmission member 241 and matches with the first transmission member 231 or the second transmission member 241, the first transmission member 231 or the second transmission member 241 can be driven to rotate synchronously, so as to switch the transmission between the first transmission group 23 and the second transmission group 24.

[0120] In order to realize the opposite directions of the power output of the first transmission group 23 and the second transmission group 24, referring to Figure 6 In one of the embodiments, the first transmission group 23 includes a first gear group, and the second transmission group 24 includes a second gear group; the number of gears of the first gear group is n, the number of gears of the second gear group is B=n+1, and n is a positive integer greater than or equal to 1.

[0121] The first gear set and the second gear set can be axis-parallel gear sets. When the axes of the gears in the gear set are parallel to each other, if the external meshing number of the gears is even, the rotation directions of the first gear and the last gear are opposite; if the external meshing number of the gears is odd, the rotation directions of the first gear and the last gear are the same.

[0122] The first transmission member 231 can be a first gear in the first transmission set 23, and the second transmission member 241 can be a first gear in the second transmission set 24. The first gears are used to be connected with the clutch member 211 and have the same rotation direction as the driving member 21.

[0123] To facilitate understanding, the cleaning assembly 10 can be provided with a cleaning rotating gear 114, which is in transmission connection with the output gears 220 of the first transmission set 23 and the second transmission set 24 and is fixedly connected with the lead screw 111, so as to drive the lead screw 111 to rotate in the first preset direction.

[0124] When n=1, the number of gears A in the first gear set is 1, only a first gear is provided, the first gear is combined with the clutch member 21112 and the cleaning rotating gear 114, the rotation direction of the first gear is opposite to that of the driving member 21, and the rotation direction of the cleaning rotating gear 114 is also opposite to that of the first gear, so as to be the same as that of the driving member 21. The number of gears B in the second gear set is 2, there are two gears, i.e., a first gear and a last gear, the rotation direction of the last gear is the same as that of the clutch member 211, and the rotation direction of the cleaning rotating gear 114 is opposite to that of the clutch member 211. It can be understood that when n=2, A=2 and B=3, the power output direction of the first gear set is opposite to that of the driving member 21, and the power output direction of the second gear set is the same as that of the driving member 21.

[0125] The number of gears in the first gear set and the second gear set is set in the embodiment, so as to control the power output directions of the two gears, and then the cleaning assembly 10 can be controlled to ascend and descend when the driving member 21 rotates forward or reversely.

[0126] In one of the embodiments, the first gear set and the second gear set share the same output gear 220, and the output gear 220 is in transmission connection with the cleaning assembly 10.

[0127] The output gear 220 is used to output driving force to the cleaning assembly 10, so as to drive the cleaning assembly 10 to rotate in the first preset direction. For example, in combination with the above embodiment, the output gear 220 is in meshing connection with the cleaning rotating gear 114, so as to drive the cleaning rotating gear 114 to rotate, and then drive the lead screw 111 fixedly connected with the cleaning rotating gear 114.

[0128] The first gear set and the second gear set share the same output gear 220 in the embodiment, so as to improve the integration of the transmission set 22, further save space, and reduce the manufacturing cost of the cleaning device 100.

[0129] In one of the embodiments, the driving member 21 comprises a driving shaft 210 configured to be axially movable; the tangential mechanism 30 is connected with the driving shaft 210; when the tangential mechanism 30 moves in the direction parallel to the axial direction of the driving shaft 210, the driving shaft 210 is synchronously driven to move in the axial direction.

[0130] In the embodiment, the tangential mechanism 30 can be connected with the driving shaft 210 through key connection, pin connection, clamping, etc., and when the tangential mechanism 30 is lifted in the direction parallel to the axial direction of the driving shaft 210, the driving shaft 210 is synchronously lifted, so as to realize the separation or combination of the clutch member 211 and the transmission group 22.

[0131] In one of the embodiments, the cleaning device 100 further comprises a swing rod, two ends of the swing rod are respectively connected with the driving shaft 210 and the cleaning assembly 10, and the swing rod is fixedly connected with the cleaning assembly 10 and swingably connected with the driving shaft 210. When the driving shaft 210 drives the cleaning assembly 10 to swing, the swing rod can be swung in the second preset direction, and the cleaning assembly 10 is driven to swing in the second preset direction.

[0132] Referring to Figure 1 and Figure 5 In one of the embodiments, the tangential mechanism 30 comprises a tangential motor 33 (not shown in the figure), a tangential transmission group 32 (not shown in the figure) and a tangential action member 31; the tangential transmission group 32 is connected with the tangential motor 33 and the tangential action member 31 respectively, and is used for transmitting the power of the tangential motor 33 to the tangential action member 31, so as to drive the tangential action member 31 to move in the direction parallel to the axial direction of the driving shaft 210; the tangential action member 31 at least partially extends to the driving shaft 210 and is connected with the driving shaft 210.

[0133] In the embodiment, the tangential motor 33 drives the tangential transmission group 32 to rotate, and the tangential transmission group 32 controls the tangential action member 31 to move in the direction parallel to the axial direction of the driving shaft 210. For example, when the tangential motor 33 rotates forward, the tangential action member 31 is lifted, so as to synchronously drive the driving shaft 210 to be lifted; when the tangential motor 33 reverses, the tangential action member 31 is lowered, so as to synchronously drive the driving shaft 210 to be lowered, but the present application is not limited thereto.

[0134] In the embodiment, the tangential action member 31 can be provided with a clamping portion, the clamping portion extends towards the driving shaft 210, and the circumferential direction of the driving shaft 210 can be provided with a protrusion, a gear or a fixed rod, etc., which are clamped and driven by the clamping portion, so as to realize the movement of the driving shaft 210 in the axial direction. In other embodiments, the tangential action member 31 can also be connected with the driving shaft 210 through key connection, pin connection, etc., and is not limited in particular.

[0135] The cleaning device 100 can further comprise a driving motor, which is configured to output a driving force to the driving member 21 to drive the cleaning assembly 10 to swing, and the tangential assembly is configured to switch the direction of the driving force transmitted to the cleaning assembly 10 to control the rotation and lifting direction of the cleaning assembly 10.

[0136] In the embodiment, the tangential motor 33 is only used for tangential movement, i.e., driving the driving shaft 210 to move in the axial direction, the driving force is small, and the required motor power is also low, so that a small motor with small space occupation can be arranged, while the driving motor for driving the cleaning assembly 10 to swing, rotate and lift can be arranged as a large power motor, so that two large power motors do not need to be arranged in the cleaning device 100 at the same time, and the space occupation can be reduced. At the same time, in the prior art, two large power motors are needed to control the swing or rotation of the cleaning assembly 10 respectively, so that transmission groups 22 need to be arranged on the cleaning assembly 10 to realize transmission control. In the embodiment, the tangential transmission group 32 is arranged only from the tangential motor 33 to the tangential action member 31, which further reduces the space occupation and simplifies the structure of the cleaning device 100, which is beneficial to the optimal design of the arrangement of the cleaning device 100.

[0137] In other embodiments, the tangential motor 33 can not be arranged, and the driving motor is connected to the tangential mechanism 30 and the driving shaft 210 respectively. The tangential mechanism 30 can comprise a trigger mechanism, which is configured to control the movement of the tangential mechanism 30 when it is necessary to change the above working conditions, such as encountering situations that need to avoid obstacles, interrupt cleaning or avoid part of the cleaning surface, etc. The space occupation is further reduced and the space utilization is improved.

[0138] In one of the embodiments, the movable distance of the tangential action member 31 in the direction parallel to the axial direction of the driving shaft 210 is m; the movable distance of the driving shaft 210 in the axial direction is n; the gap between the first transmission member 231 and the second transmission member 241 is c; the width of the clutch member 211 is d; and m≥n≥c>d.

[0139] In the embodiment, m can be the lifting range of the tangential action member 31, i.e., the maximum lifting distance and the maximum lowering distance of the tangential action member 31 in the direction parallel to the axial direction of the driving shaft 210 is m.

[0140] In the embodiment, n can be determined by the gap between the driving shaft 210 and the housing of the cleaning device 100. The housing of the cleaning device 100 can be used to accommodate the driving member and can comprise an upper housing and a lower housing. The sum of the gap between the driving shaft 210 and the upper housing and the gap between the driving shaft 210 and the lower housing is the movable distance of the driving shaft 210 in the axial direction.

[0141] Wherein, c can be a preset gap of the first transmission member 231 and the second transmission member 241 along the axial direction of the driving shaft 210, and the clutch member 211 is arranged in the gap.

[0142] Wherein, d can be the width dimension of the clutch member 211 along the axial direction of the driving shaft 210.

[0143] Since the clutch member 211 is arranged between the first transmission member 231 and the second transmission member 241, in order to realize transmission and separation, c>d is set, so that the clutch member 211 can be completely separated from the first transmission member 231 or the second transmission member 241, and interference is avoided.

[0144] Since the driving shaft 210 drives the clutch member 211 to move in the gap between the first transmission member 231 and the second transmission member 241, in order to enable the clutch member 211 to be connected with the first transmission member 231 and the second transmission member 241 respectively, the movable distance of the driving shaft 210 along the axial direction is n≥c. When n=c, the clutch member 211 is matched with the first transmission member 231 or the second transmission member 241, and when n>c, the driving shaft 210 can be driven by the tangential action member 31 along the axial direction, so that the abutting force of the clutch member 211 and the first transmission member 231 or the second transmission member 241 is increased, the connection reliability is enhanced, and disconnection in the transmission process is avoided.

[0145] Since the tangential action member 31 drives the driving shaft 210 to move along the axial direction, m≥n is set. When m=n, the tangential action member 31 drives the driving shaft 210, thereby driving the clutch member 211 to be matched with the first transmission member 231 or the second transmission member 241. In order to increase the abutting force of the clutch member 211 and the first transmission member 231 or the second transmission member 241 and enhance the connection reliability, disconnection in the transmission process is avoided, m>n can also be set. Since the movable distance of the tangential action member 31 is larger, when the driving shaft 210 reaches the maximum stroke and is limited, the tangential action member 31 still has the force to continue to move, thereby applying the force along the axial direction to the driving shaft 210, and then increasing the abutting pressure of the clutch member 211 and the first transmission member 231 or the second transmission member 241.

[0146] Corresponding to the foregoing application function implementation device embodiment, the present application also provides a cleaning device 100, a cleaning equipment 1000 and corresponding embodiments.

[0149] The cleaning device 1000 provided by the embodiment is provided with the cleaning device 100, and the cleaning device 100 occupies a smaller space, so that a larger space can be obtained in the body of the cleaning device 1000, which is beneficial to the arrangement and design of the modules of the cleaning device 1000, improves the space utilization of the cleaning device 1000, and is also beneficial to reducing the volume of the cleaning device 1000 and realizing compact design.
