Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cleaning devices, and particularly relates to a cleaning module and a cleaning device. BACKGROUND

[0002] The cleaning device is a common intelligent cleaning appliance, such as a robot vacuum cleaner, an automatic sweeper, etc., which can move on a surface to be cleaned (such as a floor, a step surface, a table top, etc.) and clean the surface to be cleaned. The current cleaning device has good cleaning effect on ordinary stains, but it is difficult to clean stubborn stains completely. CONTENT OF THE UTILITY MODEL

[0003] The present application provides a cleaning module and a cleaning device, which can solve the technical problem that the current cleaning device cannot meet different cleaning requirements to some extent.

[0004] In the first aspect of the present application, a cleaning module is provided, which comprises a support connected with a main machine of the cleaning device, a driving member connected with the support, wherein the driving member is provided with an output shaft, a rotary vibration member rotationally connected with the output shaft in an eccentric manner relative to the rotation shaft of the output shaft, the rotary vibration member performs planar rotary vibration around the rotation shaft of the output shaft, and a first cleaning member connected with the rotary vibration member.

[0005] In the second aspect of the present application, a cleaning device is provided, which comprises a main machine and the above-mentioned cleaning module, wherein the cleaning module is connected with the main machine, and at least the first cleaning member of the cleaning module extends outside the main machine.

[0006] The cleaning module provided according to one or more embodiments of the present application comprises a support, a driving member, a rotary vibration member and a first cleaning member. The support serves as a support base for mounting the driving member and the rotary vibration member. The output shaft of the driving member is used to output rotary power, and the rotary vibration member is rotationally connected to the output shaft in a manner eccentric to the rotation axis of the output shaft. Since the power input point of the rotary vibration member is arranged eccentric to the rotation axis of the output shaft, when the output shaft rotates around its own rotation axis, the rotary vibration member arranged eccentric to the output shaft rotates in a plane around the rotation axis of the output shaft. And since the rotary vibration member is rotationally connected to the output shaft, the rotary vibration member does not rotate while rotating in the plane. Thus, vibration is generated by the rapid planar rotary vibration, and the direction of the vibration can be any direction in the plane perpendicular to the rotation axis of the output shaft. The first cleaning member is connected to the rotary vibration member, and the first cleaning member generates vibration towards different directions by rapidly planar rotary vibration of the rotary vibration member. When the first cleaning member contacts the surface to be cleaned, the first cleaning member vibrates towards different directions relative to the surface to be cleaned, which can clean the surface to be cleaned, clean stubborn stains such as dried stains and heavy oil stains, and improve the cleaning effect, so that the cleaning equipment configured with the cleaning module can meet different cleaning requirements.

DETAILED DESCRIPTION

[0024] In order to make the person skilled in the art to which the present application belongs more clearly understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor are within the scope of protection of the present application.

[0025] In addition, reference numerals and / or reference letters can be repeated in different examples in the present application, and such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or arrangements discussed. In addition, the present application provides examples of various specific processes and materials, but the person skilled in the art can realize the application of other processes and / or the use of other materials.

[0026] The current cleaning device, the cleaning module of which usually adopts the rotating or reciprocating movement of the cleaning member to clean the stains on the ground. The rotating or reciprocating movement is good for cleaning ordinary stains, but due to the single running direction of rotation and reciprocating movement, the current cleaning device is difficult to clean stubborn stains.

[0027] Based on the above technical problems, the present application provides a cleaning module and a cleaning device, which aims to improve the cleaning effect of the cleaning device and can clean dry stains, heavy oil stains and other stubborn stains.

[0028] The specific technical solutions will be described in detail with reference to the accompanying drawings that are not necessarily drawn to scale. Identical or similar reference numerals can be used to refer to identical or similar parts throughout the various drawings. The use of identical or similar reference numerals in different drawings does not mean that all drawings described by the identical or similar reference numerals form a single or same embodiment. The accompanying drawings schematically illustrate various embodiments discussed in the present application in an exemplary and non-limiting manner.

[0029] Figure 1 A structural schematic diagram of a cleaning device 1000 according to an embodiment of the present application is shown. In combination with Figure 1 The cleaning device 1000 can be a sweeping robot, a floor washing machine, or the like. The cleaning device 1000 includes a main machine 200 and a cleaning module 100 mounted on the main machine 200. The main machine 200 is configured with a walking device 300 and can automatically travel or be pushed by a user to move on a surface to be cleaned (for example, a floor, a step surface, a table top, or the like). For the convenience of description, the traveling direction of the cleaning device 1000 is defined as the X direction. The main machine 200 can also be configured with a rotating brush 400 to clean a large volume of garbage. The cleaning module 100 is provided with a cleaning member 110. The cleaning module 100 is mounted on the main machine 200, and at least the cleaning member 110 of the cleaning module 100 protrudes outward from the main machine 200, for example, at least part of the cleaning member 110 is located at the bottom of the main machine 200 and exposed outward. The cleaning member 110 can be in contact with the surface to be cleaned, and the cleaning member 110 moves relative to the surface to be cleaned, thereby wiping off stains on the surface to be cleaned.

[0030] The movement form of the cleaning member 110 relative to the surface to be cleaned can directly affect the cleaning effect of the cleaning device 1000. In the cleaning module 100 provided by the first aspect of the present application, the cleaning member 110 can move in different directions relative to the surface to be cleaned, effectively removing stubborn stains on the surface to be cleaned. The cleaning module 100 provided by the first aspect of the present application will be described in detail below with reference to the corresponding drawings.

[0031] Please refer to Figure 2 A structural schematic diagram of a cleaning module 100 according to an embodiment of the present application is shown. The cleaning module 100 includes a support 130, a driving member 140, a rotary vibration member 120, and a first cleaning member 111. The support 130 serves as a support base and is used to mount the driving member 140 and the rotary vibration member 120. The entire cleaning module 100 is connected to the main machine 200 of the cleaning device 1000 through the support 130. The driving member 140 has an output shaft 141 for outputting rotary power. The rotary vibration member 120 is rotationally connected to the output shaft 141 in an eccentric manner relative to the rotation axis A of the output shaft 141, as shown in Figure 2That is, the torque output by the output shaft 141 is not transmitted to the whirling member 120, the whirling member 120 does not rotate actively, and the posture of the whirling member 120 does not change.

[0032] Since the power input point of the whirling member 120 is arranged eccentrically relative to the rotation axis A of the output shaft 141, when the output shaft 141 rotates around its own rotation axis, the whirling member 120 arranged eccentrically relative to the output shaft 141 performs planar whirling vibration around the rotation axis A of the output shaft 141, and the motion trajectory of the whirling member 120 performing planar whirling vibration is as shown in FIG. 2. Figure 3 It can be understood that the planar whirling vibration of the whirling member 120 cannot be interpreted as a horizontal plane in a limiting manner, but should be understood as a plane perpendicular to the rotation axis A of the output shaft 141. When the rotation axis A of the output shaft 141 is arranged vertically, the whirling member 120 whirls in a horizontal plane accordingly.

[0033] Please refer to FIG. 2, Figure 4 The radius of the planar whirling vibration of the whirling member 120 is the eccentricity a between the whirling member 120 and the output shaft 141, that is, the distance between the power input point of the whirling member 120 and the rotation axis A of the output shaft 141. Each point on the whirling member 120 performs planar whirling vibration with the eccentricity a as the radius, and the motion trajectory of each point on the whirling member 120 is a circle, but the rotation centers of the planar whirling vibration of the points on the whirling member 120 are different. For convenience of description, the motion form of the whirling member 120 that "does not rotate itself and performs planar whirling vibration as a whole" is defined as whirling.

[0034] When the whirling member 120 performs planar whirling vibration, the position of the whirling member 120 in the plane perpendicular to the rotation axis A of the output shaft 141 changes, and the change direction of the position can be any direction in the plane, so that vibration is generated through rapid planar whirling vibration. The first cleaning member 111 is connected to the whirling member 120, and can be arranged on the side of the whirling member 120 away from the driving member 140. The first cleaning member 111 performs rapid planar whirling vibration with the whirling member 120, and generates vibration in different directions. When the first cleaning member 111 contacts the surface to be cleaned, the first cleaning member 111 vibrates in different directions relative to the surface to be cleaned, can disturb the stains on the surface to be cleaned in different directions, and accelerate the separation of the stains from the surface, so that the stains can be cleaned more quickly and efficiently, and the cleaning effect on stubborn stains such as dried stains and heavy oil stains is also good. Compared with conventional rotation or reciprocating motion, since the motion direction of the rotation or reciprocating motion is a single direction, the disturbance direction of the stains is also a single direction, so the cleaning effect on stubborn stains is weak. The cleaning module 100 provided by the present application can disturb the stains in different directions, so that the cleaning effect is better.

[0035] AsFigure 5 As shown in the figure, in an embodiment, the rotary vibration piece 120 comprises a rotary vibration plate 121 and at least one active eccentric shaft 122 connected. The rotary vibration plate 121 is used to mount the first cleaning piece 111, and the outer contour of the rotary vibration plate 121 should not exceed the outer contour of the first cleaning piece 111 to avoid occupying additional space. The rotary vibration plate 121 and the first cleaning piece 111 can be connected in any way such as bonding, screw connection, buckle connection, magnetic attraction connection, and the specific structure is not limited by the application. The at least one active eccentric shaft 122 is arranged in a manner eccentric to the rotation axis A of the output shaft 141, one end of the active eccentric shaft 122 is fixedly connected with the rotary vibration plate 121 to make the rotary vibration plate 121 and the active eccentric shaft 122 move together. The other end of the active eccentric shaft 122 is rotatably connected with the output shaft 141, so as to realize the rotary connection of the rotary vibration piece 120 and the output shaft 141. In other embodiments, an eccentric shaft can also be arranged on the output shaft 141, one end of the eccentric shaft is connected with the output shaft 141, and the other end is connected with the rotary vibration piece 120. At least one end of the eccentric shaft is rotatably connected with the connected part, so as to realize the rotary connection of the rotary vibration piece 120 and the output shaft 141.

[0036] The rotary vibration piece 120 needs to mount the first cleaning piece 111, and if a larger cleaning area is to be realized, the area of the first cleaning piece 111 is also larger. In order to stably mount the first cleaning piece 111, the rotary vibration piece 120 should also have a larger mounting plane. Obviously, the area of the rotary vibration piece 120 is much larger than that of the output shaft 141, and single-point fixation can cause unstable posture of the rotary vibration piece 120 when moving, and even generate noise. Therefore, please refer to Figure 6 In some embodiments, the support piece 130 is provided with at least one auxiliary hanging point shaft 133, the auxiliary hanging point shaft 133 is rotatably connected with the support piece 130, and the auxiliary hanging point shaft 133 is used to simulate the function of the output shaft 141, but does not output power.

[0037] Correspondingly, the rotary vibration piece 120 also comprises at least one driven eccentric shaft 123, the driven eccentric shaft 123 is rotatably connected with the auxiliary hanging point shaft 133 in a manner eccentric to the rotation axis of the auxiliary hanging point shaft 133, the driven eccentric shaft 123 has the same function as the active eccentric shaft 122, and the eccentric distance b of the driven eccentric shaft 123 and the auxiliary hanging point shaft 133 is equal to the eccentric distance a of the rotary vibration piece 120 and the output shaft 141, as shown in the figure. Figure 7 By arranging the driven eccentric shaft 123 and the auxiliary hanging point shaft 133, the rotary vibration piece 120 has multiple fixation points, and multi-point fixation ensures that the posture of the rotary vibration piece 120 is stable when moving.

[0038] As shown in the figure, Figure 5 and Figure 6As shown, the cleaning module 100 of this embodiment is provided with two driven eccentric shafts 123 and an auxiliary hanging point shaft 133, the two driven eccentric shafts 123 are symmetrically distributed on both sides of the driving eccentric shaft 122, and the three are in a triangular distribution. Meanwhile, the axis of the driving eccentric shaft 122 passes through the symmetry axis of the rotary vibration plate 121 and the first cleaning element 111. The use of this symmetrical distribution structure can reduce the noise during the movement of the rotary vibration element 120.

[0039] It can be understood that in other embodiments, the driven eccentric shaft 123 can also be part of the auxiliary hanging point shaft 133, one end of the driven eccentric shaft 123 is connected to the auxiliary hanging point shaft 133, and one end is connected to the rotary vibration element 120. At least one end of the driven eccentric shaft 123 is rotationally connected to the connected part, that is, the rotary connection between the rotary vibration element 120 and the auxiliary hanging point shaft 133 can be achieved.

[0040] In order to further reduce the noise during the movement of the rotary vibration element 120, please refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 In some embodiments, at least one of the connection between the driving eccentric shaft 122 and the rotary vibration plate 121, the connection between the driven eccentric shaft 123 and the rotary vibration plate 121, the connection between the auxiliary hanging point shaft 133 and the support 130, and the connection between the output shaft 141 and the support 130 is provided with a damping element 154. The damping element 154 is a flexible and elastically deformable material, such as rubber, silicone, etc. The specific form of the damping element 154 can be a gasket or a washer, which is not limited by the present application. As an embodiment, the damping element 154 can be provided at the connection between the driving eccentric shaft 122 and the rotary vibration plate 121, the connection between the driven eccentric shaft 123 and the rotary vibration plate 121, the connection between the auxiliary hanging point shaft 133 and the support 130, and the connection between the output shaft 141 and the support 130. Through the damping element 154, the rotary vibration plate 121 and the driving eccentric shaft 122 and the driven eccentric shaft 123 are flexibly connected, and the support 130 and the auxiliary hanging point shaft 133 and the output shaft 141 are flexibly connected, thereby weakening the transmission of vibration.

[0041] Please refer to Figure 5 In some embodiments, the rotary vibration plate 121 is provided with two or more mounting holes 1211, the driving eccentric shaft 122 and the driven eccentric shaft 123 respectively extend into the corresponding mounting hole 1211, and the cross-sectional size of the driving eccentric shaft 122 and the driven eccentric shaft 123 is smaller than that of the corresponding mounting hole 1211, so that there is an annular gap between the shaft and the hole wall. Each mounting hole 1211 is provided with a damping element 154, the damping element 154 is located in the annular gap and is clamped by the corresponding shaft and the hole wall.

[0042] Please refer to Figure 7 and Figure 8Since the driving eccentric shaft 122 and the driven eccentric shaft 123 need to perform planar rotary vibration, a plurality of through holes 137 are needed to be arranged on the support 130, the size of the through holes 137 is larger than the size of the corresponding driving eccentric shaft 122 and the driven eccentric shaft 123, and the driving eccentric shaft 122 and the driven eccentric shaft 123 always do not contact the hole wall of the through holes 137 when performing planar rotary vibration. Based on the above, the auxiliary hanging point shaft 133 and the output shaft 141 cannot be fixed through the through holes 137, and other support structures need to be arranged on the support 130.

[0043] Please refer to Figure 7 In some embodiments, the auxiliary hanging point shaft 133 is installed on the support 130 through the mounting cover 134. The mounting cover 134 is a cover body, which is buckled at the installation position of the auxiliary hanging point shaft 133 to prevent foreign matter from entering. In combination with Figure 6 and Figure 7 The mounting cover 134 and the auxiliary hanging point shaft 133 are also provided with a damping member 154. The damping member 154 is sleeved on the top of the auxiliary hanging point shaft 133, the mounting cover 134 is buckled outside the damping member 154 and the auxiliary hanging point shaft 133, and abuts against the damping member 154. The mounting cover 134 is connected with the support 130, for example, the mounting cover 134 can be locked on the support 130 through screws.

[0044] Please refer to Figure 6 and Figure 8 In some embodiments, the driving member 140 is installed on the support 130 through the shell 138. The output shaft 141 is encapsulated in the shell 138, and is connected with the shell 138 through the bearing 144. The damping member 154 is also arranged between the output shaft 141 and the shell 138. The damping member 154 is sleeved on the top of the output shaft 141, and the inner wall of the shell 138 extends a limiting convex ring, which is sleeved outside the damping member 154 and abuts against the damping member 154.

[0045] The connection between the rotary vibration member 120 and the output shaft 141 can be up and down floating along the extension direction of the rotation axis A of the output shaft 141, for the convenience of description, the extension direction of the rotation axis A of the output shaft 141 is defined as the Z direction. In combination with Figure 8In some embodiments, an elastic member 152 is arranged between the rotating and vibrating member 120 and the output shaft 141, and abuts against both the rotating and vibrating member 120 and the output shaft 141. Under elastic deformation of the elastic member 152, the rotating and vibrating member 120 and the output shaft 141 can move relative to each other in the Z direction, which can improve the ground contact effect of the first cleaning member 111 attached to the rotating and vibrating member 120, so that the frictional resistance of the first cleaning member 111 to the surface to be cleaned is relatively stable when the rotating and vibrating member 120 rotates and vibrates, and the vibration transmitted from the cleaning module 100 to the main machine 200 is reduced to some extent. The elastic member 152 can be any part that can be elastically deformed, such as a rubber pad, a silica gel pad, a disc spring, a round wire spring, a metal spring, etc., which is not limited in the present application.

[0046] The elastic member 152 is arranged in a compressed state, and provides an elastic force in the Z direction to the rotating and vibrating member 120 and the output shaft 141. The abutting points of the elastic member 152 and the rotating and vibrating member 120 and the abutting points of the elastic member 152 and the output shaft 141 should be distributed as much as possible in the Z direction. For example, the elastic member 152 is clamped between the rotating and vibrating member 120 and the output shaft 141, or the elastic member 152 is sleeved on a certain part, and the two ends abut against the bodies of the two parts.

[0047] Figure 9 Fig. 6 shows a structural schematic diagram of the output shaft 141 of the cleaning module 100 in some embodiments, in combination with Figs. 1 to 5, Figure 9 and Figure 10 The output shaft 141 is provided with an eccentric hole 1411 arranged eccentrically relative to the rotation axis A of the output shaft 141, and the axis of the eccentric hole 1411 is parallel to but not collinear with the rotation axis. The rotating and vibrating member 120 is provided with an eccentric shaft with a receiving cavity 124, and the eccentric shaft extends into the eccentric hole 1411 to close the receiving cavity 124. Figure 10 Fig. 7 shows a structural schematic diagram of the rotating and vibrating member 120 of the cleaning module 100 in some embodiments. The rotating and vibrating member 120 includes a rotating and vibrating plate 121, a driving eccentric shaft 122 and a driven eccentric shaft 123, and the driving eccentric shaft 122 and the driven eccentric shaft 123 are each provided with a receiving cavity 124. The elastic member 152 is arranged in the receiving cavity 124, one end of the elastic member 152 abuts against the bottom of the receiving cavity 124, and the other end abuts against the bottom of the eccentric hole 1411.

[0048] In other embodiments, an eccentric protrusion arranged eccentrically relative to the rotation axis A of the output shaft 141 can also be arranged on the output shaft 141, and the axis of the eccentric protrusion is parallel to but not collinear with the rotation axis. The rotating and vibrating member 120 is provided with a cavity, and the eccentric protrusion and the elastic member 152 both extend into the cavity. One end of the elastic member 152 abuts against the bottom of the cavity, and the other end abuts against the eccentric protrusion, which can also improve the ground contact effect of the first cleaning member 111.

[0049] In some embodiments, considering the rotation of the rotating part 120 relative to the support part 130, a plurality of wear-resistant parts can be arranged between the rotating part 120 and the support part 130. The arrangement of the wear-resistant parts makes the rotating part 120 and the support part 130 have a fixed gap, and the wear-resistant parts can reduce the collision and noise between the two layers of plates, and contribute to further reducing the noise when the rotating part 120 moves. The number of wear-resistant parts can be multiple, and the multiple wear-resistant parts are distributed at intervals so that the rotating part 120 and the support part 130 remain parallel. The wear-resistant parts can be non-metal materials, such as plastics, rubbers, etc.

[0050] Please refer to Figure 11 , which shows the structure diagram of the cleaning device 1000 from the bottom view in some other embodiments. The cleaning device 1000 can also include an edge brush 500 and a rolling brush 600 to improve the cleaning effect. Please refer to Figure 12 , which shows the exploded view of the cleaning module 100 in some embodiments. The cleaning module 100 also includes a second cleaning part 112, which is connected to the support part 130, specifically arranged on the side of the support part 130 away from the driving part 140. The first cleaning part 111 and the second cleaning part 112 can be cleaning cloths, wool, brushes, etc., which clean the ground.

[0051] The second cleaning part 112 is a stationary part relative to the support part 130. Considering that the first cleaning part 111 performs planar oscillation without rotation when working, the first cleaning part 111 and the second cleaning part 112 need to maintain a certain interval to avoid interference with the rotation of the rotating part 120. The local gap between the first cleaning part 111 and the second cleaning part 112 can be zero when the first cleaning part 111 is in the rotating state, but there is no contact force between the first cleaning part 111 and the second cleaning part 112. The rotating part 120 generates a certain reaction force on the support part 130 when working. The second cleaning part 112 on the support part 130 generates a friction force with the surface to be cleaned, which can offset the reaction force generated by the rotating part 120 to some extent, thereby reducing the shaking of the cleaning module 100 transmitted to the entire cleaning device 1000.

[0052] When the cleaning module 100 works, the first cleaning part 111 rotates relative to the surface to be cleaned to quickly remove stains on the surface to be cleaned. Since the wiping direction of the first cleaning part 111 on the stains is indefinite, some stains may be separated from the surface to be cleaned but not attached to the first cleaning part 111. The second cleaning part 112 moves unidirectionally relative to the surface to be cleaned, and the moving direction is the driving direction of the cleaning device 1000 carrying the cleaning module 100. The second cleaning part 112 can remove residual stains and water stains generated during cleaning of the first cleaning part 111 from the surface to be cleaned, thereby improving the cleaning effect.

[0053] Therefore, please refer to Figure 11 In some embodiments, the second cleaning member 112 is located outside the first cleaning member 111, that is, the first cleaning member 111 is closer to the center of the cleaning device 1000 than the second cleaning member 112. And along the running direction X of the cleaning device 1000, the second cleaning member 112 is located behind the first cleaning member 111, the first cleaning member 111 first washes the surface to be cleaned, and then the second cleaning member 112 wipes the cleaned part, realizing the cleaning mode of "washing first and wiping later".

[0054] In combination Figure 11 And Figure 12 In some embodiments, the cleaning module 100 further comprises a flexible member 151 connected between the first cleaning member 111 and the second cleaning member 112, so that the first cleaning member 111 and the second cleaning member 112 form a unit when installed, facilitating assembly. The flexible member 151 can adopt elastic ropes, flexible cloth and other parts, which are not limited by the present application. Further, in some embodiments, the flexible member 151 adopts flexible cloth, which covers the gap between the first cleaning member 111 and the second cleaning member 112, avoiding the intrusion of foreign matter between the first cleaning member 111 and the second cleaning member 112, and even the inside of the cleaning module 100 when the cleaning module 100 is working.

[0055] Please refer to Figure 11 And Figure 12 In some embodiments, the cleaning module 100 further comprises a threading strip 153 for installing wire harness and pipeline, and the threading strip 153 is installed on the support member 130. The flexible member 151 is connected to the first cleaning member 111, the second cleaning member 112 and the threading strip 153 at the same time, the flexible member 151 is connected to the outer periphery of the first cleaning member 111, the outer periphery of the flexible member 151 is connected to the second cleaning member 112 and the threading strip 153, and the second cleaning member 112 and the threading strip 153 enclose the flexible member 151 and the first cleaning member 111.

[0056] The specific shape and number of the first cleaning member 111 and the second cleaning member 112 can be determined according to the shape and size of the cleaning device 1000 in which they are installed. For example, the specific shape of the first cleaning member 111 and the second cleaning member 112 can be long strip, rectangle, circular arc, circle, etc., which are not limited by the present application. The material of the first cleaning member 111 and the second cleaning member 112 can be the same or different. For example, in some embodiments, the first cleaning member 111 adopts cloth with rougher surface and greater friction, which can efficiently scrape stains; the second cleaning member 112 adopts cloth with finer surface and better water absorption, which can wipe water stains and residual stains.

[0057] With Figure 11As shown in the most common round-shaped sweeping robot in the market, the cleaning module 100 is arranged at the rear of the sweeping robot, occupying an area less than a semicircular region. The outer edge of the second cleaning member 112 coincides with the outer contour of the sweeping robot, and the second cleaning member 112 is in the shape of a C. The first cleaning member 111 is in the shape of a D, and is completely embedded in the area surrounded by the C-shaped second cleaning member 112.

[0058] In some embodiments, the first cleaning member 111 and the second cleaning member 112 each have a large area, and the first cleaning member 111 is mounted on the rotary vibration member 120, which provides a mounting plane. Accordingly, the support member 130 also needs to provide a mounting plane for the second cleaning member 112. Please refer to Figure 13 In some embodiments, the support member 130 includes a support body 131 and an extension edge 132. The support body 131 is used to mount the driving member 140, and a corresponding avoiding hole 137 is also provided in the support body 131 to avoid the eccentric shaft of the rotary vibration member 120. The extension edge 132 is arranged at the periphery of the support body 131 and is used to mount the second cleaning member 112.

[0059] Please refer to Figure 14 In order to reduce the Z-direction height of the cleaning module 100, in some embodiments, the support body 131 has a rotary vibration cavity 1311 for accommodating the rotary vibration member 120, and the extension edge 132 is connected to the support body 131 and located at the periphery of the opening of the rotary vibration cavity 1311, thereby forming the layout of the first cleaning member 111 inside and the second cleaning member 112 outside.

[0060] When the cleaning module 100 is working, it needs to wet the ground with water, which can be sprayed from the main machine 200 of the cleaning device 1000 and sprayed in front of the first cleaning member 111 and the second cleaning member 112. In some embodiments, water can also be directly supplied to the first cleaning member 111 and / or the second cleaning member 112, so that the first cleaning member 111 and / or the second cleaning member 112 are wetted, thereby improving the cleaning effect. Please refer to Figure 13 The cleaning module 100 also includes at least one pump 160 and a liquid outlet nozzle 170 in communication with the pump 160 through a pipeline (not shown in the figure). The pump 160 and the liquid outlet nozzle 170 are arranged on the support member 130 and are used to pump liquid to the first cleaning member 111 and / or the second cleaning member 112. The liquid can be water, cleaning agent, or a mixture of the two. The liquid outlet nozzle 170 is connected to the downstream end of the pipeline and is used to discharge the liquid to the first cleaning member 111 and / or the second cleaning member 112. As an embodiment, the liquid outlet nozzle 170 can wet the first cleaning member 111 and the second cleaning member 112 at the same time.

[0061] The liquid outlet nozzles 170 can be in direct contact with the first cleaning member 111 and / or the second cleaning member 112, or can be provided with through holes 1312 in the parts below the liquid outlet nozzles 170, as shown in the figure. The liquid outlet nozzles 170 extend into the through holes 1312 to supply liquid to the first cleaning member 111 and / or the second cleaning member 112. Alternatively, the liquid output by the liquid outlet nozzles 170 flows to the first cleaning member 111 and / or the second cleaning member 112 through the through holes 1312. Figure 14 As shown in the figure, the liquid outlet nozzles 170 extend into the through holes 1312 to supply liquid to the first cleaning member 111 and / or the second cleaning member 112. Alternatively, the liquid output by the liquid outlet nozzles 170 flows to the first cleaning member 111 and / or the second cleaning member 112 through the through holes 1312.

[0062] Figure 13 The cleaning module 100 of some embodiments shown contains four liquid outlet nozzles 170, which supply liquid to different positions of the first cleaning member 111 and the second cleaning member 112, respectively. The multiple liquid outlet points enable the first cleaning member 111 and the second cleaning member 112 to be uniformly wetted. Four fixing parts 135 are provided on the support member 130, and the four liquid outlet nozzles 170 are respectively mounted on the four fixing parts 135 with the openings downward. The support member 130 and the rotary vibration member 120 are both provided with through holes 1312 for the liquid outlet nozzles 170 to pass through. The nozzle parts of the liquid outlet nozzles 170 pass through the through holes 1312 of the support member 130 and the rotary vibration member 120 to directly spray liquid to the first cleaning member 111 and the second cleaning member 112. Considering that the rotary vibration member 120 needs to be rotated, the through holes on the rotary vibration plate 121 can be set to be relatively large to avoid interference of the liquid outlet nozzles 170 with the movement of the rotary vibration member 120. Alternatively, the nozzle parts of the liquid outlet nozzles 170 are controlled to pass through only the through holes 1312 of the support member 130. The liquid output by the liquid outlet nozzles 170 corresponding to the position of the second cleaning member 112 is directly sprayed to the second cleaning member 112, and the liquid output by the liquid outlet nozzles 170 corresponding to the position of the first cleaning member 111 flows to the first cleaning member 111 through the through holes of the rotary vibration member 120.

[0063] The pumping force of the pump 160 is derived from the rotation of the rotor. The working power of the rotor can be derived from an independently arranged motor or from the driving member 140, which is equivalent to the driving member 140 driving the rotary vibration member 120 to rotate and driving the pump 160 to operate at the same time. For details, please refer to Figure 14 In some embodiments, the driving member 140 includes a driving part 142, a transmission part 143, and an output shaft 141. The driving part 142 outputs rotational power, which can be an electric motor or a motor. The transmission part 143 is used to transmit the power of the driving part 142. The transmission part 143 includes two or more output gears 1431 for outputting power. One of the output gears 1431 is in transmission connection with the output shaft 141 to transmit power to the rotary vibration member 120 to drive the rotary vibration member 120 to rotate. At least one of the remaining output gears 1431 is in power coupling with the pump 160 to drive the pump 160 to operate, and the pump 160 pumps liquid to the liquid outlet nozzles 170. The transmission part 143 can further include a plurality of transmission gears, which can realize the functions of speed reduction and reversing.

[0064] The driving part 142, the transmission part 143 and the pump 160 in the cleaning module 100 are all rotating, which will generate working noise. Especially the driving part 142 and the pump 160, in the case that the rotation axes of the two are not collinear, the driving part 142 and the pump 160 will generate eccentric force to the support 130. Therefore, the driving part 142 and the pump 160 need to be coaxially arranged, or the pump 160 is arranged as multiple, and the multiple pumps 160 are symmetrically distributed relative to the driving part 142. Correspondingly, the number of the pump 160 can be set as even, and the even number of pumps 160 are symmetrically distributed on both sides of the driving part 142.

[0065] Please combine Figure 13 , the specific distribution of the pump 160 of the cleaning module 100 in an embodiment is shown, the pump 160 is arranged as four, the four pumps 160 are symmetrically distributed on both sides of the driving part 142 as a group, the two pumps 160 on the same side are coaxially arranged, and the pumps 160 distributed on both sides of the driving part 142 cancel part of the eccentric force, reduce the noise and the shaking of the support 130. The four pumps 160 correspond to the four liquid outlets 170 respectively, and each liquid outlet 170 independently discharges liquid.

[0066] The cleaning module 100 is installed on the main machine 200 of the cleaning equipment 1000, can be installed in the inside of the main machine 200, only the first cleaning part 111 and the second cleaning part 112 are exposed to the bottom of the main machine 200, or an avoiding area is arranged on one side of the main machine 200, and the cleaning module 100 is located in the avoiding area. The cleaning module 100 can be fixedly connected with the main machine 200 of the cleaning equipment 1000 through a threaded fastener, a buckle and the like, and the relative position between the cleaning module 100 and the main machine 200 is unchanged after installation. It can also be movably connected with the main machine 200 of the cleaning equipment 1000 through a hinge, a connecting rod mechanism, a pull rope and the like, that is, the cleaning module 100 can move together with the main machine 200, and can also rotate and / or lift relative to the main machine 200 at the same time.

[0067] Please combine Figure 14 Figure 15In some embodiments, the cleaning module 100 further comprises a connecting member 180, which is hinged with the support member 130 and the main machine 200 of the cleaning device 1000, so that the cleaning module 100 has the freedom of rotation and / or lifting relative to the main machine 200. The connecting member 180 can adopt a linkage mechanism or a component capable of adaptive deformation (e.g., a metal spring sheet, etc.). For the convenience of installation of the connecting member 180, in some embodiments, an upwardly protruding mounting seat 136 is arranged on the support member 130, and the connecting member 180 is hinged with the mounting seat 136. A cable or lifting rod is extended from the main machine 200 to connect the support member 130, and by changing the length of the cable or lifting rod exposed outside the main machine 200, the cleaning module 100 can be driven to move relative to the main machine 200, and the connecting member 180 is deformed adaptively, so that the cleaning module 100 can rotate and / or lift relative to the main machine 200, to realize the functions of obstacle avoidance, cleaning pressure adjustment, etc.

[0068] Therefore, the cleaning device 1000 provided by the present application has the functions of spin cleaning and cleaning mode of washing first and mopping later. The dirt on the surface to be cleaned is disturbed in different directions by the first cleaning member 111 of the cleaning module 100, so as to accelerate the separation of the dirt from the surface to which the dirt is attached, thereby achieving faster and more efficient cleaning of the dirt. The water stains and residual dirt left by the first cleaning member 111 are removed by the second cleaning member 112 of the cleaning module 100. The driving member 140 of the cleaning module 100 synchronously drives the pump 160 to operate, and directly supplies liquid to the first cleaning member 111 and the second cleaning member 112, thereby improving the cleaning effect. Moreover, the cleaning module 100 has a more compact structure, so that the overall size of the cleaning device 1000 is smaller. The cable or lifting rod of the cleaning device 1000 can drive the cleaning module 100 to rotate and / or lift relative to the main machine 200, to avoid obstacles on the ground or prevent the wet first cleaning member 111 and the second cleaning member 112 from contacting the carpet, and to adjust the ground pressure of the first cleaning member 111 and the second cleaning member 112, thereby further improving the cleaning effect.
