In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
In some of the flows described in the specification and claims of this application and in the above-described figures, a number of operations are included that occur in a particular order, but it should be clearly understood that these operations may be performed out of order or in parallel as they occur herein, the number of operations, e.g., 101, 102, etc., merely being used to distinguish between various operations, and the number itself does not represent any order of performance. Additionally, the flows may include more or fewer operations, and the operations may be performed sequentially or in parallel. It should be noted that, the descriptions of "first", "second", etc. in this document are used for distinguishing different messages, devices, modules, etc., and do not represent a sequential order, nor limit the types of "first" and "second" to be different.
The technical scheme of the embodiment of the application is mainly applied to the water suction type dust collector which adopts the same motor to realize liquid absorption and dust absorption.
As described in the background art, because the same motor is adopted, the requirement of dust collection operation on the working power of the motor is relatively high, and the water absorption operation motor cannot work under high power so as to avoid absorbing liquid into the motor, but the water absorption type dust collector cannot limit the high power of the motor used by a user, so that the motor of the existing water absorption type dust collector still can be provided with a plurality of gears, completely depends on the subjective motility of the user, does not use the high-grade function of the motor when absorbing water, and is fatal to the motor once misoperation exists.
Therefore, the inventor thinks that if the intelligent identification can be carried out on whether the dust collector works in the water absorption state currently, so as to control the motor to disable the high power, the use safety can be ensured. The inventor finds in research that at present, a power supply supplies power to a motor, a controller and the like of a dust collector through a power supply control module, and the power supply control module can play a role in power supply protection and the like. As the waste water barrel is arranged in the water suction type dust collector to collect sucked liquid, the intelligent detection module is correspondingly arranged to detect the liquid level usually in order to ensure the safety. When the dust collector is in a water absorption state, the power supply control module is connected with the intelligent detection module, and in addition, a first controller connected with the power supply control module and a second controller connected with the intelligent detection module are arranged in the dust collector. Therefore, when the liquid level in the waste water barrel exceeds the warning line, the second controller controls the intelligent detection module to be switched off, and at the moment, the first controller can determine that the waste water barrel exceeds the warning line according to the level change of the power supply control module, so that the motor can be controlled to stop running and the like. Accordingly, the inventor proposes a technical solution of the present application, and in an embodiment of the present application, a water suction device control system is composed of a power supply control module, an intelligent detection module, a first controller connected to the power supply control module, and a second controller connected to the intelligent detection module, wherein the power supply control module is connected to a power supply, and when the intelligent detection module and the second controller are connected to the power supply control module, the power supply control module respectively establishes a power supply path with the intelligent detection module and the second controller; the second controller responds to a power-on signal and controls the intelligent detection module to continuously perform switching operation of turning off and turning on again at intervals of preset time for multiple times, so that the power supply control module generates high and low level change due to continuous switching operation of the intelligent detection module for multiple times; and the first controller responds to the power-on signal, and controls the motor to disable the working power higher than the power threshold if the power supply control module is detected to generate the high-low level change. Because the intelligent detection module can only establish connection with the power supply control module when the dust catcher is in the state of absorbing water, at this moment, the intelligent detection module is controlled to continuously execute multiple times of switch operation through the second controller so as to generate the change of the high and low level, if the first controller detects the change of the high and low level, the dust catcher can be confirmed to be in the state of absorbing water, and at this moment, the motor can be controlled to forbid the working power higher than the power threshold value, so that the use safety is ensured. In practical application, the power of the motor is generally divided into three gears, namely a high gear, a medium gear and a low gear, and the first controller can control the motor to disable the high gear. The embodiment of the application realizes the intelligent recognition of the water absorption state of the dust collector, does not need to increase an additional detection assembly, can realize detection by utilizing the existing components, guarantees the use safety of the water absorber, reduces the potential safety hazard, and prolongs the service life of the motor.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic structural diagram of an embodiment of a vacuum cleaner control system according to an embodiment of the present disclosure, the vacuum cleaner control system is embedded in a vacuum cleaner body structure, and may include:
a power supply control module 101, a smart detection module 102, a first controller 103 connected to the power supply control module 101, and a second controller 104 connected to the smart detection module 102 and the power supply control module 101, respectively; wherein, the power supply control module 101 is connected with a power supply.
When the smart detection module 102 is connected to the power supply control module 101, the power supply control module 101 establishes a power supply path with the smart detection module 102 and the second controller 104, respectively, to supply power to the smart detection module 102 and the second controller 104.
Wherein, the second controller 104 is configured to control the liquid level detection module 102 to perform at least one switching operation that is turned off and turned on again at a first predetermined time interval in response to a power-on signal, so that the power supply control module 101 generates a high-low level change due to at least one switching operation of the smart detection module 102;
the first controller 101 is configured to respond to the power-on signal, and control the motor to disable the operating power higher than the power threshold if the power supply control module 101 detects that the high-low level change is generated.
The power threshold may be set in conjunction with the actual application, for example, high gear power may be disabled.
The power-on signal may be an electric signal generated when the vacuum cleaner control system obtains electric energy to start operation.
The intelligent detection module 102 and the power supply control module 101 may be connected when the vacuum cleaner is switched to a water suction state. A control switch for switching to a water absorption state may be provided in the vacuum cleaner, and a user may switch the vacuum cleaner to the water absorption state by operating the control switch, so that the intelligent detection module 102 is connected to the power supply control module 101.
The first controller and the second controller may be specifically MCUs (micro controller units).
Wherein, if intelligent detection module 102 switches on, intelligent detection module 102 forms the return circuit with power supply control module 101 this moment, power supply control module 101 can produce great electric current, otherwise, when intelligent detection module 102 switches off, power supply control module 101 can produce less electric current, first controller 103 can detect the level change of power supply control module 101 this moment, according to this kind of high-low level change, can confirm that the dust catcher is in the state of absorbing water, the high power of forbidden motor promptly, in order to guarantee the safety in utilization.
It should be noted that the smart detection module 102, the second controller 104 and the power supply control module 101 are connected when the vacuum cleaner is in a water suction state. Second controller 104 can also be connected with level sensor, and of course this level sensor can integrate to in the circuit board of second controller, and level sensor is used for detecting the liquid level change in the waste water bucket to when the liquid level change satisfies the early warning condition, inform second controller 104, second controller 104 can control intelligent detection module and turn off, so that power supply control module takes place the level change, and first controller 103 confirms that the waste water bucket is full according to this level change promptly, then the control motor stop operation.
In some embodiments, the first controller 103 is further configured to control the motor to operate normally in response to the power-on signal if the power-supply control module 101 does not detect the high-low level change.
If the power supply control module 101 does not generate the high-low level change, it indicates that the intelligent detection module 102 is not in use, the second controller 104 is not powered on, and the vacuum cleaner is not in a water absorption state but in a dust absorption state, so that the motor can be controlled to normally operate.
In addition, in order to improve the determination accuracy, in some embodiments, the second controller 104 may specifically control the smart detection module 102 to perform a switching operation of turning off for multiple times and turning on again at intervals of a first predetermined time in response to a power-on signal; wherein, the interval between two adjacent switching operations is the second preset time.
Wherein the first predetermined time and the second predetermined time may be different; for example, the first predetermined time is 2ms (milliseconds, the same applies hereinafter), and the second predetermined time is 3ms at maximum. At this time, when the maximum of the second predetermined time is 3ms, the second predetermined time may be turned off for 2ms and then turned on for 3ms, or turned on for 2ms and then turned off for 3ms, so as to form different high and low level alternation.
Of course, as an alternative, the first predetermined time and the second predetermined time may be the same, for example, 2ms (millisecond), and then the high-low level change detected by the first controller 103 is 2ms high level and 2ms low level change alternately.
In order to reduce the false determination rate, in some embodiments, the first controller 103 may specifically control the motor to disable the operating power higher than the power threshold in response to the power-on signal if the power supply control module 101 detects that the high-low level change is generated within a third predetermined time.
The third predetermined time may be set according to the number of times of the switch operation performed by the smart detection module 102, the first predetermined time, the second predetermined time, and the like. In some specific embodiments, when the third predetermined time is 20ms, the first predetermined time and the second predetermined time are the same and both are 2ms, and the power control module 101 generates three periods of high and low level changes. That is, within the third predetermined time 20ms, the power supply control module 101 generates a 12ms high-low level change.
In some embodiments, when the first controller 103 detects that the power control module 101 generates the high-low level change, controlling the motor to disable the operating power above the power threshold includes:
when the power supply control module 101 detects that the high and low level changes are generated, if a switching request for switching the motor to the working power higher than the power threshold is received, the motor is controlled to stop running.
In practical application, a plurality of gears are correspondingly arranged on the motor to facilitate control of a user, and the working power of some gears causes overlarge suction force generated by the motor and is not suitable for a water absorption state. The switching request for switching the electric machine to the operating power higher than the power threshold may therefore refer to a switching request for a preset gear. In some scenarios, the vacuum cleaner only has two gears, namely a high gear and a low gear, when the high-low level change can be detected, if a high gear switching request is received, the motor is controlled to stop running.
The intelligent detection module 102 may include an analog switch circuit, and the second controller 104 is connected to the analog switch circuit, and controls the analog switch circuit to be turned off and turned on to turn off and turn on the intelligent detection module 102.
The second controller 104 specifically controls the analog switch to perform a switching operation of turning off at least once and turning on again at predetermined time intervals.

The first MOS transistor Q1 is specifically a P-channel MOS transistor, and the first inductor L1 and the second inductor L2 may be specifically magnetic beads.
The fifth resistor R5 is a small-resistance high-power resistor, so that current sampling can be realized. When the dust collector is started, the power supply starts to supply power to the dust collector control system, the first controller detects the power-on signal to control the conduction of the first MOS tube, so that the intelligent detection module and the second controller obtain electric energy, the second controller detects the power-on signal at the moment, the intelligent detection module can be controlled to execute the switching operation of at least one turn-off and the turn-on at preset intervals, for example, the switching operation can be executed for 3 times, when the intelligent detection module is conducted, the positive power supply interface SM + can generate large current, when the intelligent detection module is turned off, compared with the intelligent detection module, the current of the positive power supply interface SM + is reduced.
