The present disclosure relates to the technical field of intelligent devices, and in particular to a movable operating apparatus and an automatic pool cleaning device using same.
With the development of intelligent robot technology, robots are emerging in various subdivided scenarios in people's daily lives, replacing manual labor, reducing users' working time, and improving happiness. For example, a swimming pool cleaning robot can automatically travel on a bottom wall and side walls of a swimming pool and suck dirt during traveling.
A traditional swimming pool cleaning robot is connected to a control device on the shore via a cable for power supply and control. In order to simplify the structure, there are currently swimming pool cleaning robots that use batteries for local power supply, and communicate with a user's remote control terminal through wireless communication for control, such as power on and off, motion control, etc. In this way, the cable can be omitted.
However, without the cable, the swimming pool cleaning robot has limited power. When its battery is low, the swimming pool cleaning robot often can only stay at the bottom of the swimming pool and does not have the energy to climb the side wall to reach a water surface. This leads to a major difficulty, which is that it is difficult for a user to move the swimming pool cleaning robot out of the swimming pool from the bottom of the swimming pool. Usually, the swimming pool cleaning robot can only be hooked out by extending a hooked rod, etc. into the water. However, this operation is a bit challenging and it is not easy to hook the swimming pool cleaning robot; and this operation is also troublesome, which is not conducive to enriching the user experience.

At present, swimming pool cleaning robots are widely used, which can help people and automatically clean underwater surfaces of swimming pools, replacing manual labor, improving efficiency, and enriching user experience. However, during the transforming from traditional swimming pool cleaning robots that use wired power supply and communication to new swimming pool cleaning robots with wireless communication and local battery power supply, it is difficult for a user to take it out of a swimming pool due to there is no cable on the wireless swimming pool cleaning robot, and it can only be taken out with the help of tools, resulting in poor user experience.

The movable operating apparatus includes a buoyance operating end, which is located in the accommodation chamber 111 and is locked and limited by an electric control lock 202. Illustratively, the buoyance operating end may be a floating box, in which a cavity may be included. Optionally, the cavity may also be filled with air or other gases that increase buoyance.
In practical applications, when the automatic pool cleaning device 100 is working normally, the buoyance operating end is restricted in the accommodation chamber 111. In
In some embodiments, the number of buoyance operating ends 201 may be more than one, that is, there may be multiple buoyance operating ends 201, which are arranged at different positions on the top surface of the automatic pool cleaning device. Multiple buoyance operating ends 201 may work individually or together, that is the buoyance operating ends 201 may be released selectively or together. For example, if one of the buoyance operating ends 201 cannot be released due to a fault, the release of another buoyance operating end 201 can also ensure normal working. Alternatively, multiple buoyance operating ends 201 can be released together, which increases the buoyance and is also convenient for the user to drag the automatic pool cleaning device.
To illustrate the structure of the movable operating apparatus in the above examples, reference can be made to
As shown in
The electric control lock 202 includes a lock driving mechanism driven by an electric signal, and a locking member 221 driven by the lock driving mechanism. The locking member 221 limits the buoyance operating end 201 when the electric control lock 202 is in the locked state, and removes the limitation when the electric control lock 202 is in the unlocked state. The locking member 221 may be a locking tongue of the electric control lock 202. As shown in
The lock control circuit 204 is electrically coupled to the electric control lock 202, and is configured to send an unlocking signal to the electric control lock 202 to unlock the electric control lock 202 in response to an unlocking trigger signal generated when the automatic pool cleaning device 100 stops working, such that the buoyance operating end 201 floats and carries the traction rope 203 out of the accommodation chamber and to the water surface.
In some embodiments, the electric control lock 202 may be a magnetic lock. The electric control lock 202 includes a conductor, which is electrically coupled to the lock control circuit 204 and generates a current when a voltage is applied across the conductor by the unlocking signal of the lock control circuit 204, so as to form a magnetic field acting force on the locking member 221, to drive the locking member 221 to remove the limitation. As an example, the conductor may be, for example, silicon steel, and the locking member 221 may be made of a metal material (such as iron) that can be affected by magnetic force.
In some embodiments, when the electric control lock 202 is in the locked state, the locking member 221 maintains an extended state. An elastic member may be provided at its rear end, and the elastic member is, for example, an elastic piece or a spring. When the elastic member is not in a compressed state, the locking member 221 maintains the extended state and fits the opening of the buoyance operating end 201. When the electric control lock 202 is unlocked, a voltage is applied across the conductor, to generate a current flowing through the conductor. A magnetic field is formed around the current, and a magnetic attraction force is generated on the locking member 221, to pull the locking member 221 to the left to complete the removal of the limitation, and the elastic member is compressed due to the movement of the locking member 221. When the voltage disappears, the locking member 221 can be restored under an elastic force of the elastic member.
In some embodiments, the traction rope 203 may be, for example, made of nylon material, PVC material, etc. The traction rope 203 is preferably made of a corrosion-resistant material, or may be made of a waterproof material or a material undergone waterproof treatment.
In some embodiments, the automatic pool cleaning device 100 stops working when, for example, it receives a shutdown instruction (e.g., through wireless communication) or the battery is low (e.g., when the power supply voltage is lower than a preset threshold). The lock control circuit 204 can obtain the unlocking trigger signal generated from the working stopping circumstances described above, such as the shutdown instruction or the low battery power, and output an unlocking instruction to the electric control lock 202. The unlocking instruction may be an output voltage signal applied across the conductor in the electric control lock 202.
The automatic pool cleaning device 100 may include a controller 103. The controller 103 may be a main controller 103 or other auxiliary controllers 103 of the automatic pool cleaning device 100. The controller 103 may be implemented as a control chip or include a control chip. Each pin of the control chip may be connected to a corresponding detection circuit to detect the shutdown instruction, a voltage detection signal of the battery for determining whether the power is low, and other information, so as to generate the unlocking trigger signal and transmit it to the lock control circuit 204. In some embodiments, the control chip may be implemented as a microcontrol unit (MCU), a system on a chip (SoC), or an application specific integrated circuit (ASIC). In a possible example, the control chip may be, for example, an SoC or MCU chip of the PY32F030 series, HK32W030 series, STM32G030 series, N32G030 series, etc. It should be understood that the above are merely some examples of implementations of the control chips. Of course, there are many other types of existing chips that can realize the functions of the control chips in the above embodiments. Although the applicant cannot exhaustively list the types of chips, these chips can also fall within the protection scope of the present disclosure.

An input terminal of the voltage detection circuit 105 is electrically coupled to the battery 106, for outputting the voltage detection signal corresponding to an output voltage of the battery 106. The controller 103 generates the unlocking trigger signal and sends the unlocking trigger signal to the lock control circuit 204 based on receiving the shutdown signal from the wireless communication circuit 104 or based on determining that the battery 106 is low according to the voltage detection signal of the battery 106. Illustratively, the voltage detection circuit 105 may be implemented based on a sampling circuit for the output voltage of the battery 106, such as a voltage divider circuit. Illustratively, the controller 103 may include an analog-to-digital converter, a comparator, etc. The analog-to-digital converter is configured to convert the analog voltage detection signal into a digital quantity representing the output voltage of the battery 106. The comparator may be configured to compare the digital quantity with a preset threshold to determine whether the output voltage of the battery 106 is lower than the certain voltage threshold and thus has low power.
Illustratively, the controller 103 may further include an electric supply terminal 134. The battery 106 may be coupled to an input terminal of a power management circuit 107, and an output terminal of the power management circuit 107 is coupled to the electric supply terminal 134 to power the controller 103. Illustratively, the power management circuit 107 may include a filtering circuit, a transforming circuit, and other circuits, to generate one or more power supply voltages (such as 24 V, 12 V, 5 V, 3.3 V, and the like) to adapt to different operating voltage requirements of an element.
Illustratively, the controller 103 may further include a motion control instruction terminal 135 and a water sucking and draining control instruction terminal 136. The motion control instruction terminal 135 may be coupled to a motion drive motor 108 (or a water sucking/draining drive motor) of an action mechanism (such as the two pairs of cleaning rollers in
It should be understood that when the power of the automatic pool cleaning device 100 is low, the automatic pool cleaning device 100 moves to the edge of the pool, and the buoyance operating end 201 is released. The buoyance operating end 201 is also close to the shore, which is more convenient for the user to take and operate, thus enriching the user experience.
Further, as shown in
As an example, the lock control circuit includes: a first switch unit 301, a first voltage control unit 302, a second switch unit 303, a second voltage control unit 304, a third switch unit 305, and a first signal output interface 306.
The first switch unit 301 includes: a first terminal, a second terminal, and a third terminal. The third terminal is electrically coupled to the input terminal of the lock control circuit, to set on/off between the first terminal and the second terminal based on the input unlocking trigger signal, and the second terminal is grounded.
The first voltage control unit 302 includes: a first voltage terminal electrically coupled to a power supply terminal 307, a second voltage terminal electrically coupled to the first terminal of the first switch unit 301, and a second signal output terminal for outputting a first switching signal based on a voltage difference between the first voltage terminal and the second voltage terminal. The power supply terminal 307 is configured to apply an input voltage.
The second switch unit 303 includes: a fourth terminal, a fifth terminal, and a sixth terminal. The sixth terminal is electrically coupled to the second signal output terminal of the first voltage control unit 302 to set on/off between the fourth terminal and the fifth terminal based on the first switching signal, and the fourth terminal is electrically coupled to the power supply terminal 307.
The second voltage control unit 304 includes: a third voltage terminal electrically coupled to the fifth terminal of the second switch unit 303, a fourth voltage terminal grounded, and a third signal output terminal for outputting a second switching signal based on a voltage of the third voltage terminal.
The third switch unit 305 includes: a seventh terminal, an eighth terminal, and a ninth terminal. The ninth terminal is electrically coupled to the third signal output terminal of the second voltage control unit 304 to set on/off between the seventh terminal and the eighth terminal based on the second switching signal, and the eighth terminal is grounded.
The first signal output interface 306 is configured to be electrically coupled to the lock driving mechanism, and includes a first power output pin 361 and a second power output pin 362. The first power output pin 361 is electrically coupled to the power supply terminal 307, and the second power output pin 362 is electrically coupled to the seventh terminal of the third switch unit 305.
The first switch unit 301, the second switch unit 303, and the third switch unit 305 have the same on/off state. Illustratively, the first switch unit 301, the second switch unit 303, and the third switch unit 305 may be implemented by triodes or MOS transistors. In order to achieve the same on/off state, as an example, the first switch unit 301 may be an N-type triode or MOS transistor, the second switch unit 303 may be a P-type triode or MOS transistor, and the third switch unit 305 may be an N-type triode or MOS transistor. Illustratively, the first voltage control unit 302 and the second voltage control unit 304 may be implemented by voltage divider circuits, which can proportionally adjust the output voltage to a voltage range suitable for the transistors.
When the first switch unit 301 is turned on by the unlocking trigger signal, the second switch unit 303 is turned on by the first switching signal, and the third switch unit 305 is turned on by the second switching signal, such that an output voltage generated between the first power output pin 361 and the second power output pin 362 of the first signal output interface for the lock driving mechanism serves as the unlocking signal. Specifically, when the first switch unit 301, the second switch unit 303, and the third switch unit 305 are not turned on, the second power output pin 362 is disconnected and cannot form a loop, which is coupled to the electric control lock, with the first power output pin 361. While when the third switch unit 305 is turned on as the first switch unit 301 and the second switch unit 303 are turned on, the second power output pin 362 is pulled down to the ground, and a voltage difference is formed between the voltage on the second power output pin 362 and the voltage on the first power output pin 361 from the power supply terminal 307, where the voltage difference is output to the electric control lock for unlocking.

R5 and R6 form a voltage divider circuit with a voltage divider point located at the base electrode, such that when the voltage of an input signal is greater than an operating voltage range of Q2, the voltage of the input signal can also be adjusted into the operating voltage range of Q2.
The first voltage divider circuit includes: a first resistor R1 and a second resistor R2.

The third power output pin is electrically coupled to the power supply terminal, and the fourth power output pin is electrically coupled to a source electrode of the NMOS.
Specifically, the controller transmits a high-level unlocking trigger signal to turn on Q2, and the voltage divider point between R1 and R2 outputs a divided voltage of the voltage between the power supply terminal and the collector electrode of Q2 (the potential of the collector electrode of Q2 is pulled down by the grounded terminal after Q2 is turned on), where the divided voltage is at low-level. The low-level voltage acts on the base electrode of Q1 to turn Q1 on, and the collector electrode of Q1 outputs a high-level voltage, which is divided by R3 and R4 and output to the gate electrode of MOSA, to turn MOSA on and pull the potential of the fourth power output pin 2 of J2 down to the ground. The third power output pin 1 of J2 is connected to the power supply terminal, and J2 thus outputs a voltage of 24V to the electric control lock at this time.

Ideally, the position of the buoyance operating end where it emerges from the water surface is as close to the shore as possible to facilitate the user's access. When the automatic pool cleaning device stops working, if it does not have the function of automatically moving close to the edge of the pool, the inconvenience of accessing the buoyance operating end is increased.
To this end, in some embodiments, the buoyance operating end may include a swimming mechanism (not shown), and a swimming drive motor (not shown) configured to drive the swimming mechanism to act. The swimming drive motor may drive the swimming mechanism to swim after the buoyance operating end floats, so as to move the buoyance operating end to the edge of the pool.
Referring to
Illustratively, the swimming drive motor may be coupled to the battery via an electric line to obtain power supply. Optionally, the electric line may be hidden in the traction rope 203, or may be arranged parallel to the traction rope 203. Alternatively, the buoyance operating end 201 may carry a second battery, and the swimming drive motor may be coupled to the second battery carried by the buoyance operating end 201 to obtain power supply.
As an example, the swimming drive motor controls the swimming mechanism to swim in at least one direction in response to a swimming trigger signal. In an example, the swimming drive motor may be electrically coupled to a swimming control terminal of the controller, and the swimming control terminal may transmit the swimming trigger signal after the lock control signal output terminal transmits the unlocking trigger signal, so as to trigger the working of the swimming drive motor. Alternatively, the swimming drive motor may be electrically coupled to a trigger component (e.g., a travel switch, or a metal contact point), and the trigger component may be provided on the buoyance operating end 201 and/or the housing. When the buoyance operating end 201 floats, for example, the travel switch is pressed or released, or the metal contact point is disconnected, etc., generating the swimming trigger signal and then transmitting it to the swimming drive motor, so that the swimming drive motor can drive the swimming mechanism to swim.
In some embodiments, the swimming mechanism may include one or a pair of propellers, etc., which drive the buoyance operating end 201 to move when rotating. Illustratively, the swimming mechanism may swim in a random direction, and can reach the edge of the pool as long as it swims in one direction on the water surface of the pool. Correspondingly, the length of the traction rope 203 may be set according to actual requirements. For example, the length of the traction rope 203 may be set relatively long so that when the buoyance operating end 201 swims, the automatic pool cleaning device 100 will not be affected as much as possible. For another example, if the driving force of the swimming mechanism is large enough to drive the automatic pool cleaning device 100, the length of the traction rope 203 may be relatively short to drive the automatic pool cleaning device 100 to move close to the edge of the pool, which also makes it easier for the user to take the automatic pool cleaning device out of the pool.
In an embodiment of the present disclosure, an automatic pool cleaning device may also be provided, including: a housing, where the housing is provided with an accommodation chamber on its surface; a movable operating apparatus of any one of the above embodiments, where the movable operating apparatus is provided in the accommodation chamber; and a circuit system arranged in the housing, where the circuit system includes a battery, a wireless communication circuit, and a controller, the controller is coupled to the battery and the wireless communication circuit, and the controller is electrically coupled to a lock control circuit in the movable operating apparatus.
To sum up, the embodiments of the present disclosure provide the movable operating apparatus and the automatic pool cleaning device using same. The automatic pool cleaning device performs wireless communication and uses a battery. The movable operating apparatus includes: at least one buoyance operating end, located in the accommodation chamber on the surface of the automatic pool cleaning device, and connected to the automatic pool cleaning device via the traction rope; the electric control lock, including the lock driving mechanism driven by an electric signal, and the locking member driven by the lock driving mechanism, where the locking member limits the buoyance operating end when the electric control lock is in a locked state, and removes the limitation when the electric control lock is in an unlocked state; and the lock control circuit, electrically coupled to the electric control lock, and configured to transmit the unlocking signal to the electric control lock to unlock the electric control lock in response to the trigger signal generated when the automatic pool cleaning device stops working, such that the buoyance operating end floats and carries the traction rope out of the accommodation chamber to a water surface; where the buoyance operating end is configured to move the automatic pool cleaning device out of a swimming pool in response to a user's operation. With the movable operating apparatus, the wireless automatic pool cleaning device can be taken out of the pool conveniently and quickly.
