This embodiment provides a sewage water route on-off mechanism, and the effect lies in simplifying sewage discharge system's waterway structure, reduces waterway structure part fault rate and the clean maintenance cost of system, prolongs the life of mechanism.

As shown in fig. 1-2, the present embodiment provides a cleaning robot, which is an intelligent household appliance, such as an automatic sweeper, an intelligent dust collection robot, a floor mopping/brushing robot, a window climbing robot, etc., and can automatically complete cleaning work in a region by means of certain artificial intelligence. The cleaning robot generally adopts a brushing and vacuum mode, dust on the ground is firstly absorbed into a self dust collecting box, and then the ground is scrubbed through a wet cleaning head 61, so that the function of cleaning the ground is completed.

The cleaning robot is remotely controlled by a remote controller or operated by an operation panel on the mobile platform 60, a control system, a driving system, a cleaning system, an energy system and a man-machine interaction system can be arranged in the mobile platform 60, and a sensing system can be arranged outside the mobile platform 60, so that the mobile platform 60 can pass through the sensing system, and the cleaning robot can be divided into cleaning areas with planned places in a certain area through the control system and the driving system.

In some embodiments, the mobile platform 60 may be an autonomous mobile platform 60 or a non-autonomous mobile platform 60. Autonomous mobile platform 60 means that the mobile platform 60 itself can automatically and adaptively make operational decisions based on unexpected environmental inputs; the non-autonomous mobile platform 60 itself is not capable of adaptively making operational decisions based on unexpected environmental inputs, but may execute established programs or operate in accordance with certain logic.

Specifically, the cleaning system includes at least one cleaning head 61, a water supply mechanism, a water return mechanism, and a water tank.

The cleaning head 61 reciprocates along the surface to be cleaned, cleaning cloth or a cleaning plate is arranged on the surface of the contact surface of the cleaning head 61 and the surface to be cleaned, and high-frequency friction is generated between the cleaning head 61 and the surface to be cleaned through reciprocating motion, so that stains on the surface to be cleaned are removed. In one embodiment, the cleaning head 61 includes a material having a water storage function, and the cleaning head 61 in this embodiment is a cleaning roller including a water-absorbing fabric, and the water-absorbing fabric may be a fabric strip or a fabric sheet. And still be provided with the water tank in the fuselage, generally speaking, the water tank includes clear water case and sewage case, and clear water case is configured to the storage cleaning solution, and the sewage case is configured to the storage recovery liquid, and clear water case and sewage case are independent respectively and are equipped with the opening respectively, are convenient for annotate liquid or clean. It can be understood that the clear water tank is equipped with the clear water discharge port for moist cleaning head 61, and the sewage case then is provided with sewage collection mouth and sewage discharge port, sewage collection mouth and cleaning head 61 intercommunication, the cleaning solution can form the recovery liquid after collecting cleaning head 61 and scrubbing specific surface, the sewage collection mouth then is used for retrieving the recovery liquid, avoid causing secondary pollution to specific surface, hold at the sewage case and fill up, or when needing to carry out clean maintenance to cleaning machines people, sewage case accessible sewage discharge port is with its inside recovery liquid discharge cleaning machines people.

And when the water amount in the clean water tank is insufficient or the water amount in the sewage tank is too high, a display screen and/or an indicator light and/or a loudspeaker and/or a mobile phone client program and the like of a human-computer interaction system remind a user of manual intervention or automatically return to a base station to perform cleaning solution supplement or recovered solution discharge operation.

The above-mentioned water supply device is connected directly or indirectly to the clean water outlet of the clean water tank, wherein the cleaning liquid can flow through the clean water tank to the water supply device and can wet the cleaning head 61 by the water supply device. After the cleaning head 61 cleans and cleans the surface to be cleaned, the cleaning liquid is polluted to form a recovery liquid, the recovery liquid can be extruded out by arranging a recovery mechanism such as a scraper blade and a compression roller on the cleaning head 61 through the recovery mechanism arranged on the cleaning head 61, and the water return mechanism is connected with the cleaning head 61 and a sewage tank so as to send the extruded recovery liquid into the sewage tank.

In the above sewage waterway system, the water return mechanism for collecting the recovery liquid to the sewage tank and the part for discharging the recovery liquid to the outside of the cleaning robot may be provided with the sewage waterway on-off mechanism, so as to control the sewage waterway system to perform the operation mode of collecting or discharging the recovery liquid in different modes according to the cleaning robot.

As shown in fig. 3-7, the sewage waterway switching mechanism includes an elastic hose 10, the elastic hose 10 is a through structure, and a sewage flow channel is provided inside the elastic hose 10, the elastic hose 10 can be disposed between the cleaning head 61 and the sewage tank as a component in the water return mechanism, and meanwhile, the elastic hose 10 can also be disposed at a sewage discharge port of the sewage tank to communicate the sewage tank with the external environment of the cleaning robot.

It can be understood that the flexible hose 10 is made of an elastomer material, and it needs to have a certain deformability, i.e. a certain flexible deformation function, and after being deformed, it can be restored to its original characteristics by its own elastic force. That is, the elastic tube 10, which is capable of deforming when subjected to a force and rapidly returning to its approximate original shape and size after the external force is removed again, may be made of a polymer having elasticity, or of course, may be made of other materials having the same physical properties as described above.

The opening and closing member 20 serves to control the deformation of the elastic hose 10 so that the sewage flow path is selectively blocked according to the opening and closing member 20, and in the present embodiment, the opening and closing member 20 is provided at one side portion of the elastic hose 10, and the opening and closing member 20 is movable with respect to the elastic hose 10 and between a closed position and an open position.

When the on-off member 20 is in the closed position, the on-off member 20 acts on the elastic tube 10 to deform the elastic tube 10, thereby blocking the sewage flow passage.

When the on-off member 20 is in the open position, the on-off member 20 releases the elastic tube 10, and the elastic tube 10 is elastically restored, thereby allowing the sewage flow path to be reconnected.

As shown in fig. 6 to 7, it should be noted that the moving direction of the opening/closing member 20 with respect to the elastic tube 10 is not particularly limited at this stage as long as it satisfies the freedom of reciprocating movement in the direction of approaching and separating from the elastic tube 10. For example, the switching member 20 may be a mechanical structure having a motion characteristic such as an intermittent motion mechanism, a reciprocating motion mechanism, etc., and a device member having a function characteristic such as a gap motion function, a reciprocating motion function, etc., which includes, but is not limited to, a ratchet mechanism, a sheave mechanism, a link mechanism, a cam mechanism, a cylinder, a screw mechanism, etc. When the on-off member 20 moves from the open position to the closed position, at least one position of the on-off member 20 moves from the side far from the elastic hose 10 to the direction close to the elastic hose 10 and acts on the elastic hose 10 to deform the elastic hose 10, thereby blocking the sewage flow passage, and when the on-off member 20 moves from the closed position to the open position, the on-off member 20 acts on the side of the elastic hose 10 to move from the side close to the elastic hose 10 to the direction far from the elastic hose 10, and finally releasing the elastic hose 10, so that the elastic hose 10 is restored to be connected with the sewage flow passage by the elastic force. The above-mentioned release of the elastic tube 10 by the opening/closing member 20 means a state in which the pair of opening/closing members 20 do not contact with the elastic tube 10, and the opening/closing member 20 does not exert any force on the elastic tube 10, or the force exerted on the elastic tube 10 by the opening/closing member 20 does not interrupt the sewage flow path.

In order to enable the on-off component 20 to perform corresponding actions according to different modes of the cleaning robot, the on-off component 20 is connected with a driving device 30 in a driving mode, the driving device 30 is used for driving the on-off component 20 to reciprocate between a closed position and an open position, and the driving device 30 can be connected with a control system, and the control system transmits corresponding control commands to the driving device 30 according to different working condition modes of the cleaning robot, such as a cleaning mode, a pollution discharge mode and the like, so as to control the driving device 30 to move, and control the on-off component 20 to perform movement to the open position, movement to the closed position, keeping at the open position and keeping at the closed position.

Through implementing the technical scheme, other component devices are not required to be additionally arranged in the sewage water path structure of the cleaning robot in the embodiment to control the on-off of the water path, the recovery liquid only flows in the sewage flow channel in the collection and sewage discharge processes, the on-off component 20 does not directly interfere with the sewage flow channel, namely the recovery liquid does not contact with the on-off component 20 in the collection and discharge processes, the situation that impurities in the recovery liquid enter the on-off component 20 is avoided, the sewage water path structure is simpler, compared with the traditional mode of controlling the on-off of the sewage water path through a water pump and a valve, the sewage water path on-off mechanism of the embodiment has higher reliability, and the service life of the mechanism is longer. Because other parts are not involved in the sewage flow channel, the sewage flow channel can discharge sundries with the volume matched with the diameter of the sewage flow channel, the condition that the sewage tank and the waterway structure part need to be regularly and manually cleaned and maintained is avoided, and the sewage waterway on-off mechanism is applied to the cleaning robot, so that a user can set different diameters of the sewage flow channel according to the cleaning working conditions of the cleaning robot, the elastic hose 10 can discharge sundries with different volumes, and the universality of the cleaning robot to different cleaning working conditions is improved.

As shown in fig. 4 to 7, in one embodiment, the switching member 20 has a cam structure, the switching member 20 has a curved profile, the switching member 20 is rotatably disposed at one side of the elastic tube 10 by a rotating structure such as a rotating shaft, and the driving unit 30 is used to drive the switching member 20 to rotate between the closed position and the open position.

The on-off component 20 as a cam has a contour surface which is coaxial with the rotation axis and a contour surface which is eccentric with the rotation axis, the on-off component 20 can use different contour surfaces as functional surfaces in different position states according to the control mode and the arrangement relative position of the elastic hose 10, and the contour surface acts on the elastic hose 10 in the closed position state of the on-off component 20, and in this state, the contour surface can wedge the elastic hose 10 to deform the elastic hose 10 under pressure, so that the recovery liquid in the sewage flow channel can not flow along the elastic hose 10, and in the open position state, a gap is formed between the contour surface and the elastic hose 10, or according to the scheme, the acting force applied by the contour surface to the elastic hose 10 is not enough to cut off the sewage flow channel.

The cam structure is adopted as the on-off component 20, the on-off component 20 can realize the effect that at least part of the position of the on-off component 20 moves in the direction close to and far away from the elastic hose 10 through simple rotary motion, the rotary motion only needs to provide a space for the on-off component 20 to rotate, compared with other linear motions, the component installation space occupied by the rotary motion is less, the component structure is simpler, and correspondingly, the driving device 30 and the transmission structure are also simpler.

The driving device 30 in this embodiment is a motor including a motor housing 31 as a fixed end and an output shaft 32 as an output end, the motor housing 31 is fixed to the body of the cleaning robot, and the output shaft 32 is fixedly connected to the rotating shaft of the opening/closing member 20, so that the radial and axial degrees of freedom of the opening/closing member 20 are limited, and in this state, the opening/closing member 20 can only rotate with the rotation of the motor output shaft 32, and is controlled by the motor to rotate between the closed position and the open position.

Of course, in other embodiments, as described above, the opening/closing member 20 may be a linear reciprocating mechanism, a gap moving mechanism, or other equivalent functional member device.

In order to make the on-off control process of the elastic hose 10 smoother, the sewage path on-off mechanism further includes a pressing pipe 40, the pressing pipe 40 is disposed between the on-off member 20 and the elastic hose 10, the contour curved surface slidably acts on one side of the pressing pipe 40, and the pressing pipe 40 can reciprocate between the on-off member 20 and the elastic hose 10, so that the pressing pipe 40 is linearly driven to press the elastic hose 10 or release the elastic hose 10 by the rotation of the on-off member 20.

The pipe pressing piece 40 converts the rotation motion of the on-off component 20 into linear motion to form a cam mechanism, compared with the scheme that a linear reciprocating motion mechanism is directly arranged outside the elastic hose 10, the cam mechanism is higher in transmission stability, the on-off component 20 of the cam structure can be used as a speed reduction transmission device between the motor and the pipe pressing piece 40, a speed reduction device does not need to be further arranged on the linear reciprocating motion mechanism, and the occupied installation space is smaller.

It will be appreciated that, in order to stabilize the movement of the pressing member 40 with respect to the elastic hose 10 and the opening and closing member 20, the pressing member 40 is provided with a guide structure in the cleaning robot, and the cam structure has a curved profile surface capable of driving the pressing member 40 to move in directions toward and away from the elastic hose 10 during the movement of the opening and closing member 20, the pressing member 40 being capable of pressing the elastic hose 10 when the pressing member 40 is close to the elastic hose 10, and the force between the pressing member 40 and the elastic hose 10 being insufficient to block the sewage flow path when the pressing member 40 is away from the elastic hose 10.

Specifically, in this embodiment, the elastic hose 10 has a deformation section 11 for being squeezed by the pipe member 40, the elastic hose 10 can be adapted to the installation space inside the cleaning robot, and the deformation section 11 is taken as an example and can be placed horizontally, vertically, obliquely, and the like, and since the elastic hose 10 does not have a water pump, the elastic hose 10 should be communicated with the bottom of the waste water tank when being set, so that when the on-off member 20 is in the open position state, the recovery liquid in the waste water tank can flow out of the cleaning robot along the elastic hose 10 along the gravity direction, and the elastic hose 10 should also avoid the upward-oblique and vertical arrangement as much as possible along the flow direction of the recovery liquid, so as to avoid the situation that the recovery liquid cannot cross the corresponding pipe section to discharge the cleaning robot.

Preferably, taking the supporting surface where the cleaning robot is located as a horizontal plane as an example, the deformation section 11 of this embodiment adopts a horizontally-placed installation manner, the on-off component 20 and the pressure pipe 40 are both located at the lower part of the elastic hose 10, and the lifting direction of the pressure pipe 40 is perpendicular to the deformation section 11, so that the pressure pipe 40 extrudes the elastic hose 10 along a direction perpendicular to the deformation section 11, thereby improving the effect of intercepting the sewage flow channel by the deformation of the elastic hose 10.

It is understood that the sectional shape of the elastic hose 10 may be other irregular shapes such as a circle, a rectangle, a triangle, etc., and the outer circumferential shape of the elastic hose 10 and the inner wall shape of the sewage flow path may be two same or different shapes.

Further, the contour curved surface at least comprises a first contour surface 21 and a second contour surface 22 which are connected in sequence, the pressure pipe 40 can be slidably arranged on the contour curved surface along with the self weight, and can reciprocate between the first contour surface 21 and the second contour surface 22 to lift in the rotating process of the on-off component 20.

In the present embodiment, the rotation axis of the first contour surface 21 and the rotation axis of the opening/closing member 20 are overlapped with each other, the second contour surface 22 is an eccentric portion of the opening/closing member 20, and the horizontal height when the first contour surface 21 faces the deformation section 11 is greater than the horizontal height when the second contour surface 22 faces the deformation section 11 during the rotation of the opening/closing member 20.

In order to make the movement of the pressing pipe 40 smoother during the switching between the two position states, the end of the second contour surface 22 connected to the first contour surface 21 is connected to each other, the curvature of the first contour surface is greater than that of the second contour surface, so the first contour surface is smoother than that of the second contour surface, and the end of the second contour surface is connected to the first contour surface, so the end of the second contour surface far away from the first contour surface is closer to the side close to the rotation center of the on-off component, and the curvature of the end of the second contour surface 22 close to the first contour surface 21 is gradually increased towards the end far away from the first contour surface 21, so that the lifting process of the pressing pipe 40 is uniform in the process of rotating the on-off component 20 between the two position states, and the movement stability of the mechanism is ensured.

It should be understood that the deformation state of the elastic hose 10 in the present embodiment can be understood as that the side of the elastic hose 10 away from the on-off component 20 has a relatively fixed component support, or the pipe wall of the side of the elastic hose 10 away from the on-off component 20 has no deformation capability, so that during the action of the pressing pipe member 40 on the elastic hose 10, the acted side of the elastic hose 10 is pressed toward the other side, so as to narrow the sewage flow channel and finally close the sewage flow channel, thereby cutting off the sewage flow channel. It can also be understood that the elastic hose 10 is deformed towards the whole of the side far away from the extrusion, and for example, the deformation section 11 is horizontally arranged, the deformation section 11 of the present embodiment protrudes towards the side far away from the on-off component 20 when deformed, and when the height of the deformation section 11 is large, the recovered liquid in the sewage flow channel cannot pass through the protruding part by means of the liquid weight and the hydraulic pressure, so that the sewage flow channel is cut off.

In order to further improve the effect of the elastic hose 10 extruded by the pressure pipe fitting 40, and enable the elastic hose 10 to keep the sealing and the cutoff of the sewage flow channel after being deformed, a pressure pipe convex rib 41 is arranged on one side of the pressure pipe fitting 40 close to the elastic hose 10, the pressure pipe convex rib 41 is used for extruding or releasing the elastic hose 10, in the cross section direction of the elastic hose 10, the length of the pressure pipe convex rib 41 is greater than the width of the elastic hose 10, it should be noted that the length of the pressure pipe convex rib 41 is greater than the width of the deformation section 11 after being deformed by extrusion, so that the elastic hose 10 can still be pressed by the pressure pipe convex rib 41 after being deformed, and the cutoff state is kept.

The extension directions of the pressing pipe convex rib 41 and the deformation section 11 are perpendicular to each other, so that the pressing pipe convex rib 41 can transversely extrude the elastic hose 10, and the intercepting effect of the sewage flow channel is improved.

Furthermore, as shown in fig. 4-7, the number of the pressing ribs 41 may be set according to the size of the elastic hose 10, the wall thickness and the flow rate of the elastic hose 10, for example, when the size of the elastic hose 10 is small and the internal flow rate is small, the pressing ribs 41 may be one segment, and when the size of the elastic hose 10 is large and the internal flow rate is large, the number of the pressing ribs 41 may be two or more segments, so as to increase the deformation effect of the elastic hose 10 when the pressure pipe 40 presses the elastic hose 10, and ensure that the sewage flow channel can be blocked when the on-off member 20 is in the closed position.

In order to improve the stability of the elastic hose 10 in the deformation process and improve the intercepting effect of the sewage flow channel in the intercepting state, the sewage water path on-off mechanism further comprises a deformation auxiliary component 52, an on-off gap for the elastic hose 10 to pass through is formed between the deformation auxiliary component 52 and the on-off component 20, and in connection with the installation mode, the deformation auxiliary component 52 is arranged on the upper portion of the deformation section 11, and correspondingly, the on-off component 20 and the pressing pipe fitting 40 are arranged on the lower portion of the deformation section 11.

In the horizontal direction, the on-off gap in the closed position state is smaller than the on-off gap in the open position state.

It is understood that the deformation auxiliary member 52 may be a plate-shaped member, a block-shaped member, or the like disposed along the extending direction of the deformation section 11, or may be a member disposed at an interval on the deformation section 11.
