[0002] Floor scrubbers require water to clean floors, and current technologies mostly use peristaltic pumps for water delivery and switching. However, existing peristaltic pumps have drawbacks, including high noise levels, high power consumption, and the tendency for water to flow continuously at certain angles. Therefore, there is a need for a stop valve device that can reduce power consumption, reduce noise, and prevent water from flowing continuously at certain angles. Summary of the Invention

[0008] Optionally, the first stop member includes a first stop soft rubber, and the second stop member includes a second stop soft rubber. The first stop soft rubber is used to keep the wheel assembly in the first position by interference fit with the water-stop wheel when the wheel assembly moves to the first position. The second stop soft rubber is used to keep the wheel assembly in the second position by interference fit with the water-stop wheel when the wheel assembly moves to the second position.

[0009] Optionally, the stop assembly further includes a third stop member and a fourth stop member, which are respectively disposed at both ends of the housing; the third stop member and the fourth stop member are used to limit the movement range of the wheel assembly to between the first position and the second position.

[0010] Optionally, the driving device includes a drive motor, which is coaxially arranged with the wheel axle. The drive motor drives the wheel axle to rotate, thereby moving the water-stop wheel between the first position and the second position.

[0011] Optionally, the housing further includes a motor guide portion, which is used to guide the movement of the drive motor so that when the shaft of the drive motor rotates, it drives the water-stop wheel to rotate through the wheel axle.

[0012] According to another aspect of the present disclosure, a control method for a stop valve device is provided, applied to the above-described stop valve device, the method comprising:

[0013] Receive a valve control signal for the stop valve device; the valve control signal is used to indicate the target valve status of the stop valve device.

[0014] Based on the valve control signal, the target position corresponding to the wheel assembly is determined;

[0015] A drive control signal is sent to the drive device to cause the drive device to drive the wheel assembly to move to the target position.

[0016] Optionally, determining the target position corresponding to the wheel assembly based on the valve control signal includes:

[0017] When the valve control signal indicates that the target valve is in a stop-flow state, the target position is determined to be the first position;

[0018] When the valve control signal indicates that the target valve is in a water-flow state, the target position is determined to be the second position.

[0019] Optionally, the stop valve device further includes a position detection component, which is disposed in the housing and includes a first magnetic field sensor; the wheel assembly is provided with a magnetic element; the first magnetic field sensor is located close to the first position; the method further includes:

[0020] Obtain the current valve status corresponding to the water stop valve device;

[0021] When the current valve state is a stop-flow state, the output level of the first magnetic field sensor is obtained;

[0022] An alarm signal is issued when the output level of the first magnetic field sensor is detected to be low.

[0023] Optionally, the stop valve device further includes a position detection component for detecting the current position of the wheel assembly, and the method further includes:

[0024] If the wheel assembly is detected to have moved to the target position, the drive device is controlled to stop.

[0025] According to another aspect of the present disclosure, an electronic device is provided, comprising: a processor; and a memory for storing processor-executable instructions; wherein the processor is configured to execute the instructions to implement the control method of the above-described water stop valve device.

[0026] According to another aspect of the present disclosure, a computer-readable storage medium is provided, which, when the instructions in the storage medium are executed by a processor of an electronic device, enables the electronic device to perform the control method of the above-described water stop valve device.

[0027] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0028] A water pipe is installed between the water-stopping wheel and the housing. When the wheel assembly is in the first position, the water-stopping wheel and the housing press the water pipe to keep it in a water-stopped state. When the wheel assembly is in the second position, there is a gap between the water-stopping wheel and the housing to allow the water pipe to flow. This allows the water-stopping valve device to either stop or flow. The wheel assembly is then driven to move between the first and second positions by a drive device, allowing the water-stopping valve device to switch between the water-stopping and water-flowing states. Furthermore, by combining the stop component and the position detection component, the problems of high power consumption and noise caused by maintaining the drive operation state to keep the water-stopping valve device in a water-flowing or water-stopping state can be avoided. It can also prevent situations where water does not flow at certain angles.

[0039] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0040] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0041] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0042] Please see Figures 1-4 , Figure 1 This is a schematic diagram of a water-stop valve device according to an exemplary embodiment. Figure 2 This is a schematic diagram of a wheel assembly according to an exemplary embodiment. Figure 3 This is a schematic diagram of a stop valve device in a stopped state according to an exemplary embodiment. Figure 4 This is a schematic diagram illustrating a water-stop valve device in a water-flow state according to an exemplary embodiment. Figure 1 and Figure 2 As shown, the water-stop valve device may include a housing 1, a water pipe 2, a wheel assembly 3, a drive device 4, and a stop assembly 5. The wheel assembly 3 may include a water-stop wheel 31 and a wheel axle 32. The housing 1 may be provided with a sliding groove 11, which can be used to guide the movement of the wheel axle 32. The drive device 4 can be used to drive the wheel assembly 3 to move between a first position and a second position. The water pipe 2 can be used to transport the water required by the floor scrubber, and the water pipe 2 can be disposed between the water-stop wheel 31 and the housing 1. Figure 3 As shown, when the wheel assembly 3 is in the first position, the water-stopping wheel 31 and the housing 1 press against the water pipe 2 to keep the water pipe 2 in a water-stopping state. Figure 4 As shown, when the wheel assembly 3 is in the second position, there is a gap between the water-stopping wheel 31 and the housing 1, allowing the water pipe 2 to be in a water-flowing state. The stop assembly 5 can be used to keep the wheel assembly 3 in the first or second position when it moves to the first or second position.

[0043] In the above embodiment, a water pipe 2 is disposed between the water-stopping wheel 31 and the housing 1. When the wheel assembly 3 is in the first position, the water-stopping wheel 31 and the housing 1 press the water pipe 2 to keep the water pipe 2 in a water-stopped state. When the wheel assembly 3 is in the second position, there is a gap between the water-stopping wheel 31 and the housing 1 to keep the water pipe 2 in a water-flowing state. This can realize the water-stopping or water-flowing state of the water-stopping valve device. Then, the driving device 4 drives the wheel assembly 3 to move between the first and second positions, which can realize the switching between the water-stopping state and the water-flowing state of the water-stopping valve device. Furthermore, by combining the stop component 5 and the position detection component 6, the problems of high power consumption and high noise caused by keeping the water-stopping valve device in a water-flowing or water-stopping state by maintaining the driving operation state can be avoided, and the situation where there is no water flow at certain angles can also be avoided.

[0044] In one specific embodiment, the aforementioned water-stop valve device may further include a position detection component 6, which may be disposed in the housing 1. The position detection component 6 may include a first magnetic field sensor 61 and a second magnetic field sensor 62. The wheel assembly 3 may be provided with a magnetic element 33, which may include a magnet. The first magnetic field sensor 61 is located near a first position, and the second magnetic field sensor 62 is located near a second position. The first magnetic field sensor 61 and the second magnetic field sensor 62 can be used to convert the sensed magnetic field and its changes into electrical signals. When the wheel assembly 3 is in the first position, the magnetic element 33 is close to the first magnetic field sensor 61, so that the first magnetic field sensor 61 can detect a high level, and correspondingly, the second magnetic field sensor 62 can detect a low level. When the wheel assembly 3 is in the second position, the magnetic element 33 is close to the second magnetic field sensor 62, so that the second magnetic field sensor 62 can detect a high level, and correspondingly, the first magnetic field sensor 61 can detect a low level. The position detection of the wheel assembly 3 can be achieved by the output levels of the first magnetic field sensor 61 and the second magnetic field sensor 62. Specifically, the first magnetic field sensor 61 and the second magnetic field sensor 62 may include Hall sensors.

[0045] In one specific embodiment, the magnetic element 33 can be disposed on the water-stop wheel 31. When the wheel assembly 3 is in the first position, the magnetic element 33 on the water-stop wheel 31 can be close to the first magnetic field sensor 61 so that the first magnetic field sensor 61 detects a high level; when the wheel assembly 3 is in the second position, the magnetic element 33 on the water-stop wheel 31 can be close to the second magnetic field sensor 62 so that the second magnetic field sensor 62 detects a high level. Specifically, the water-stop wheel 31 may include a circular plane, and the aforementioned magnetic element 33 can be disposed on the circular plane of the water-stop wheel 31.

[0046] In one specific embodiment, the stop assembly 5 may include a first stop and a second stop, which may be respectively disposed at both ends of the housing 1. The first stop can be used to keep the wheel assembly 3 in the first position when it moves to the first position; the second stop can be used to keep the wheel assembly 3 in the second position when it moves to the second position. Specifically, the first stop may include a first magnet, and the second stop may include a second magnet. The first magnet and the magnetic element 33 on the wheel assembly 3 can attract each other, and the second magnet and the magnetic element 33 on the wheel assembly 3 can attract each other. When the wheel assembly 3 is in the first position, the attraction between the first magnet and the magnetic element 33 on the wheel assembly 3 can keep the wheel assembly 3 in the first position; when the wheel assembly 3 is in the second position, the attraction between the second magnet and the magnetic element 33 on the wheel assembly 3 can keep the wheel assembly 3 in the second position.

[0047] In one specific embodiment, the first stop member may include a first stop soft rubber, and the second stop member may include a second stop soft rubber. The first stop soft rubber can be used to hold the wheel assembly 3 in the first position by interference fit with the water-stop wheel 31 when the wheel assembly 3 moves to the first position; the second stop soft rubber can be used to hold the wheel assembly 3 in the second position by interference fit with the water-stop wheel 31 when the wheel assembly 3 moves to the second position. Specifically, the water-stopping wheel 31 may also be equipped with a third stop rubber 34. When the wheel assembly 3 is in the first position, the third stop rubber 34 on the water-stopping wheel 31 generates friction through an interference fit with the first stop rubber, achieving positioning and stopping during the water-stopping process. Correspondingly, when the wheel assembly 3 is in the second position, the third stop rubber 34 on the water-stopping wheel 31 generates friction through an interference fit with the second stop rubber, achieving positioning and stopping during the water-flowing process. This maintains the water-flowing or water-stopping state of the water-stopping valve device, thus avoiding the problems of high power consumption and noise caused by maintaining the drive operation state to keep the water-flowing or water-stopping valve device in a water-flowing or water-stopping state. It is understood that the above-mentioned friction can be generated by overcoming external disturbances; when there are no external disturbances, there is no such friction. When the water stop valve is in the water stop state, the interference fit between the third water stop soft rubber and the first stop soft rubber generates static friction force f, the reaction force F1 generated by the deformation of the water pipe 2, and the reaction force F2 of the groove where the wheel axle 32 is located on the wheel assembly 3. The above three forces (including f, reaction force F1 and reaction force F2) can achieve three-force balance to ensure the friction self-locking of the wheel assembly 3. The above friction force and the damping of the drive device 4 can counteract the elastic force of the water pipe 2. When the wheel assembly 3 reaches the first position or the second position, the drive device 4 stops running but can still realize the water flow or water stop of the water stop valve. This can reduce the running time of the drive device 4 during the operation of the water stop valve and effectively extend the service life of the drive device 4, thereby extending the service life of the water stop valve.

[0048] In one specific embodiment, the stop assembly 5 may further include a third stop member 53 and a fourth stop member 54, which are respectively disposed at both ends of the housing 1; the third stop member 53 and the fourth stop member 54 are used to limit the movement range of the wheel assembly 3 to between the first position and the second position. Specifically, the third stop member 53 and the fourth stop member 54 may be stop ribs. The aforementioned third stop member 53 and fourth stop member 54 can prevent excessive displacement of the wheel assembly 3.

[0049] In one specific embodiment, the driving device 4 may include a drive motor, which is coaxially arranged with the axle 32. The drive motor can rotate the axle 32 to move the water-stop wheel 31 between a first position and a second position. Specifically, the drive motor drives the axle 32 to rotate, and the axle 32 contacts the housing with sufficient friction to generate relative displacement between the wheel assembly 3 and the housing.

[0050] In one specific embodiment, the housing 1 further includes a motor guide portion, which guides the movement of the drive motor so that when the drive motor shaft rotates, it drives the water-stop wheel 31 to rotate via the wheel axle 32. Specifically, the motor guide portion restricts the drive motor body to allow the drive motor shaft to rotate, and the water-stop wheel 31 to rotate via the wheel axle 32.

[0051] In one specific embodiment, the floor scrubber may include a stable water outlet device and a water shut-off valve device. The stable water outlet device may include the machine body, a clean water tank, a first air pipe, a first valve, and a second air pipe. The machine body can have a water outlet pipe with an inlet and an outlet; the clean water tank is hollow and can form a closed water storage chamber, the bottom wall of which can be provided with a drain outlet. The clean water tank is detachably constrained to the machine body, and the drain outlet of the clean water tank can be connected to the inlet of the water outlet pipe; the first air pipe can be constrained to the machine body and can have a first air inlet and a first air outlet, the first air inlet being used to connect to the external environment; a first valve can be provided on the first air pipe and can be used to control the opening and closing of the first air inlet; a second air pipe can be provided inside the clean water tank, the second air pipe can have a second air inlet and a second air outlet, the second air inlet being connected to the first air outlet of the first air pipe, and the second air outlet being located above the outlet of the water outlet pipe; thus, the outlet of the water outlet pipe can discharge water at a uniform speed when the first valve is open and the first air inlet is open. Furthermore, the principle behind the uniform flow of water in the clear water tank is as follows: the pressure exerted on the liquid surface in the clear water tank, which is level with the second air outlet of the second air pipe, is atmospheric pressure. Since the outlet of the water pipe is located below the second air outlet, the water flowing out from the outlet of the water pipe is only outward under the pressure of the layer of water between the outlet of the water pipe and the second air outlet. Because the height of the layer of water between the outlet of the water pipe and the second air outlet remains constant, the water flowing out from the outlet of the water pipe completely disregards the drop in the liquid level above the second air outlet in the clear water tank, and always flows out very evenly. It does not slow down as the liquid level in the clear water tank drops, until all the liquid above the second air outlet in the clear water tank has flowed out.

[0052] Please see Figure 5 , Figure 5 This is a flowchart illustrating a control method for a water-stop valve device according to an exemplary embodiment. Figure 5As shown, the control method for this stop valve device can be applied to the aforementioned stop valve device, and specifically may include the following steps:

[0053] S501: Receives valve control signals for the stop valve device.

[0054] In one specific embodiment, the valve control signal can be used to indicate the target valve state of the stop valve device. The valve control signal may include a target valve state identifier. The target valve state identifier can be used to indicate the target valve state of the stop valve device.

[0055] S502: Determine the target position of the wheel assembly based on the valve control signal.

[0056] In one specific embodiment, the target location may refer to the location that needs to be moved to. The target location may include a first location or a second location.

[0057] In one specific embodiment, step S502 above may include:

[0058] When the valve control signal indicates that the target valve is in a stop-flow state, the target position is determined as the first position;

[0059] When the valve control signal indicates that the target valve is in the water-flow state, the target position is determined as the second position.

[0060] In one specific embodiment, if the target valve status identifier is a stop-flow status identifier, the target position can be determined as a first position; if the target valve status identifier is a flow-through status identifier, the target position can be determined as a second position.

[0061] S503: Send a drive control signal to the drive unit to move the drive wheel assembly to the target position.

[0062] In one specific embodiment, the drive control signal can be used to control the drive device to drive the wheel assembly to move to the target position.

[0063] In one specific embodiment, the target motor rotation direction corresponding to the valve control signal can be determined based on the target position. Correspondingly, a drive control signal can be generated based on the target motor rotation direction. The target motor rotation direction refers to the direction in which the motor shaft needs to be controlled to rotate. The target motor rotation direction can include a first rotation direction or a second rotation direction; the first rotation direction can move the wheel assembly from a second position to a first position; the second rotation direction can move the wheel assembly from a first position to a second position. Specifically, when the target position is the first position, the target rotation direction can be determined as the first rotation direction; when the target position is the second position, the target rotation direction can be determined as the second rotation direction.

[0064] In one specific embodiment, the above method may further include:

[0065] Obtain the current valve status corresponding to the water stop valve device;

[0066] Under the condition that the valve is in a stop-flow state, obtain the output level of the first magnetic field sensor;

[0067] An alarm signal is issued when the output level of the first magnetic field sensor is detected to be low.

[0068] In one specific embodiment, the current valve state can refer to the state of the stop valve device at the current moment. The current valve state can include a stopped state or a flowing state. Specifically, when the current valve state of the stop valve device is a stopped state, the wheel assembly can be located in the first position mentioned above; when the current valve state of the stop valve device is a flowing state, the wheel assembly can be located in the second position mentioned above.

[0069] In one specific embodiment, when the current valve state is a stop-flow state, the output level of the first magnetic field sensor can be acquired in real time.

[0070] In the above embodiment, the position of the wheel assembly can be detected by the second magnetic field sensor when the water is turned off, and the output level of the first magnetic field sensor can be obtained when the current valve state is the water-stopping state. When the output level of the first magnetic field sensor is detected to be low, an alarm signal is issued to prevent the floor scrubber from stopping and leaking water.

[0071] In one specific embodiment, the above method may further include:

[0072] When the wheel assembly is detected to have moved to the target position, the control drive stops.

[0073] In one specific embodiment, during the movement of the wheel assembly controlled by the drive device, the position of the wheel assembly can be detected in real time by a first magnetic field sensor or a second magnetic field sensor. Specifically, when the target position is a first position, the output level of the first magnetic field sensor is acquired in real time, and the drive device can be stopped when a high level is detected from the first magnetic field sensor; when the target position is a second position, the output level of the second magnetic field sensor is acquired in real time, and the drive device can be stopped when a high level is detected from the second magnetic field sensor.

[0074] In the above embodiments, when the wheel assembly is detected to have moved to the target position, the drive device is controlled to stop. By combining the stop component and the position detection component, the problems of high power consumption and noise caused by keeping the water stop valve device in a water-flow or water-stopping state by maintaining the drive operation state can be avoided. This effectively extends the service life of the drive device and can also prevent situations where there is no water flow at certain angles.

[0075] In one specific embodiment, an initialization signal can be triggered when the user turns on the floor scrubber for the first time. Upon detecting the initialization signal, a valve opening signal can be generated; correspondingly, upon detecting the valve opening signal, the target position of the wheel assembly can be determined as a second position; then, a drive control signal can be sent to the drive device to cause the drive device to drive the wheel assembly to move to the aforementioned second position.

[0076] In the above embodiment, by initializing the water stop valve device to a water-flow state when the user first turns on the machine, the opening and closing states of the water stop valve device and the floor scrubber controller can be synchronized, and the floor scrubber can be quickly started and used by having the water stop valve device in a water-flow state.

[0078] The signal receiving module 610 can be used to receive valve control signals for the stop valve device; the valve control signals are used to indicate the target valve status of the stop valve device.

[0079] The target position determination module 620 can be used to determine the target position corresponding to the wheel assembly based on the valve control signal;

[0080] The mobile drive module 630 can be used to send drive control signals to the drive unit so that the drive unit drives the wheel assembly to move to the target position.

[0081] In one specific embodiment, the target location determination module described above may include:

[0082] The first determining module can be used to determine the target position as the first position when the valve control signal indicates that the target valve is in a stop-flow state.

[0083] The second determining module can be used to determine the target position as the second position when the valve control signal indicates that the target valve is in the water-flow state.

[0084] In one specific embodiment, the control device for the above-mentioned water-stop valve device may further include:

[0085] The current status acquisition module can be used to acquire the current valve status corresponding to the water stop valve device;

[0086] The output level acquisition module can be used to acquire the output level of the first magnetic field sensor when the current valve state is a stop-flow state.

[0087] The alarm module can be used to issue an alarm signal when the output level of the first magnetic field sensor is detected to be low.

[0088] In one specific embodiment, the control device for the above-mentioned water-stop valve device may further include:

[0089] The execution module can be used to control the drive unit to stop when the wheel assembly is detected to have moved to the target position.
