Description

Technical Field

[0001] The present invention relates to the technical field of dust collection equipment, and in particular to a combined control method for dust collection equipment. Background Art

[0002] Vacuum cleaners are a type of widely used household appliance, mainly used to clean floors, furniture and other surfaces. They create a partial vacuum, generate suction and suck up dust from the floor or other locations. At the same time, vacuum cleaners can achieve intelligent, efficient and safe control of vacuum cleaners through the comprehensive use of sensor technology, manual and automatic control, intelligent algorithms, remote and local control and other technical means.

[0003] For example, the existing patent (announcement number is CN106235963B, and the announcement date is 2020-02-07) provides a control method and a vacuum cleaner, wherein the vacuum cleaner includes a gas sensor device, and the control method includes: a detection step, wherein the detection step uses the gas sensor device to detect the gas in the vacuum cleaner and generate a corresponding gas value; a judgment step, wherein the judgment step judges whether the gas value is greater than a set threshold; and a control step, wherein the control step controls the vacuum cleaner to issue a prompt message when the gas value is greater than the set threshold. The control method can detect that the gas value obtained is greater than the set threshold and issue a prompt message when the odor in the vacuum cleaner is strong, and can promptly notify the user to handle the dirt in the vacuum cleaner, thereby avoiding further pollution of the air by the vacuum cleaner.

[0004] Although the existing technology can send out prompt information to promptly notify the user to deal with the dirt in the vacuum cleaner, it is unable to provide real-time feedback on the operating status of the vacuum cleaner, so that the user can more intuitively see the status of the vacuum cleaner, such as normal operation, normal charging, and failure, etc. At the same time, when the existing vacuum cleaner is adjusted to other working states, the vacuum module cannot be stopped from being used. When other modules of the vacuum cleaner are in use, an accidental touch may occur, causing the vacuum module to continue to operate, thereby posing certain safety hazards.

[0005] Therefore, we propose a combined control method for dust collection equipment to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a combined control method for a vacuum cleaner to solve the problem in the current market proposed by the above-mentioned background technology that the operating status of the vacuum cleaner cannot be fed back in real time, so that the user can more intuitively see the status of the vacuum cleaner, such as normal operation, normal charging, and failure, etc. At the same time, when the existing vacuum cleaner is adjusted to other working states, the vacuum cleaner module cannot be stopped from being used. When other modules of the vacuum cleaner are in use, the vacuum cleaner module may be accidentally triggered to continue running, thereby posing certain safety hazards.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a combined control method for a vacuum cleaner, comprising a control and display module, a normal working status module, a charging control module and a fault status module, wherein the control and display module comprises a self-reset knob, a host push button and a power indicator light, and the normal working status module can be controlled by the self-reset knob and the host push button, so that the vacuum cleaner body can achieve different operating effects according to needs, and the charging control module and the fault status module can be fed back through the changes of the power indicator light, and at the same time, the self-reset knob and the host push button are equipped with a voice prompt system, which can remind the user to use the control module according to needs.

[0008] Preferably, the normal working state module includes a vacuum cleaner, a vacuum module and a warning light module, and the vacuum motor arranged inside the vacuum cleaner can be started by changing the position state of the self-reset knob.

[0009] Preferably, when the dust suction module is installed to the outside of the vacuum cleaner bare machine, the position state of the dust suction module can be adjusted by adjusting the position state of the self-reset knob, the dust suction motor can be turned on, and the position state of the host push button can be changed. When the host push button is not in the middle position, the self-reset knob is in an invalid state, and the dust suction motor is turned off by default to stop dust suction. Sliding the self-reset knob cannot turn on the dust suction motor. When the host push button is in the middle position, sliding the self-reset knob is effective.

[0010] Preferably, when the warning light module is installed to the outside of the vacuum cleaner bare machine, the state of the warning light module can be adjusted by adjusting the position state of the host push button. At this time, the self-resetting knob is in an invalid state, and the vacuum cleaner motor cannot be turned on. When the host push button is in the upper warning light position, the warning light mode is turned on. When the host push button is in the lower flashlight position, the flashlight mode is turned on. At the same time, when the host push button is in the initial state, both the warning light mode and the flashlight mode are in the off state.

[0011] Preferably, when the normal working status module is in use, the color of the power indicator light can be changed through the normal working status module. When the resistance is between 5%<RC≤100%, the power indicator light is always green. When the resistance RC≤5%, the power indicator light continues to flash red until 0% and then turns off. The power of the normal working status module can be fed back through the color change of the power indicator light.

[0012] Preferably, when the charging control module is running, the power indicator light can change color. When 0%≤SoC<100%, the power indicator light continues to flash green. When SoC=100, the power indicator light stays green for 2 minutes and then goes out to enter the shutdown state. At this time, the charging status of the vacuum cleaner body can be fed back through the color change of the power indicator light. At the same time, when the vacuum cleaner body is in a normal charging state, the control key is in an invalid state, that is, the vacuuming, warning light, and flashlight cannot be turned on.

[0013] Preferably, the fault status module includes a stall fault status module, a motor battery pack short circuit detection module, a charging fault status module and a discharging fault status module. When the motor battery pack short circuit detection module detects a fault, the power indicator light is turned off and the vacuum cleaner body is shut down immediately.

[0014] Preferably, the stall fault status module performs detection operation in the vacuuming mode. When the stall is detected for 8S, the power indicator light will change its state. At this time, the power indicator light flashes alternately in green and red sequence for 3 cycles and then goes out. At the same time, the vacuuming device enters the shutdown state. The color change of the power indicator light can feedback that the vacuuming device has a stall fault, and at the same time, the vacuuming device body is controlled to enter the shutdown state. When the charging fault status module detects that the vacuuming device has a charging fault, the power indicator light will change color synchronously, thereby feedback that the vacuuming device has a charging fault. When a charging fault caused by overcurrent / overvoltage occurs, the power indicator light flashes red for 10s, and the light goes out and the device is shut down after 10s. The charging fault caused by overcurrent / overvoltage can be known by the change of the power indicator light. After the current / voltage returns to normal, the plug-in charger can continue to charge. When a charging fault caused by overtemperature caused by the battery pack detection temperature exceeding 40°C or below 5°C occurs, the power indicator light maintains its original state, and the vacuuming device enters the false charging state. If the battery does not return to normal within 5 minutes, the light is turned off and the device is shut down. After the battery pack returns to normal temperature, the plug-in charger can continue to charge.

[0015] Preferably, when the discharge fault status module detects that a fault occurs during operation of the vacuum cleaner, the power indicator light will change color synchronously. When the battery pack detection temperature exceeds 40°C or is lower than 5°C and a discharge fault caused by overtemperature occurs, the vacuum cleaner immediately stops all operations, and the power indicator light flashes red for 10 seconds. After 10 seconds, the light goes out and the machine is shut down. When the battery pack returns to normal temperature, the machine is turned on again and the vacuum cleaner body can be used normally. When a discharge fault occurs due to undervoltage, RC≤5%, the power indicator light continues to flash red until it reaches 0% and then shuts down. The change in color of the power indicator light indicates that a discharge fault has occurred in the vacuum cleaner body.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) Through the different color changes of the power indicator light itself, the working status, charging status and fault status of the vacuum cleaner can be fed back, so as to know the usage of the vacuum cleaner.

[0017] (2) The voice control system can remind the staff to use the control module as needed. After installing the vacuum module, turn the self-reset knob and the vacuum device can perform vacuuming operations. At the same time, the flashlight module and the suction nozzle are located on both sides of the vacuum device in opposite directions. Therefore, the vacuum operation can only be performed when the main push button is in the middle position. This reduces the possibility that the vacuum operation is still running when the device is in other use states, and the suction nozzle is pointed at the user, posing a safety hazard, and reduces the possibility of poor user experience.

[0018] (3) When the main push button is in the middle state, slide the self-reset knob to the left to turn on the vacuuming mode. After it is turned on, the main motor runs at 40W in the default standard mode. Slide the self-reset knob to the left again to switch to the strong mode with the main motor running at 120W. Slide the self-reset knob to the left three times to turn off the vacuuming mode. The vacuuming device is controlled by the self-reset knob, and the two gears can be adjusted according to needs, thereby improving the vacuuming effect.

[0019] (4) After the vacuum module is installed, push the main unit button upward so that when the main unit button is in the warning light position, the warning light cannot be turned on, and the vacuum motor is turned off to stop the vacuum operation. Push the main unit button downward so that when the main unit button is in the flashlight position, the flashlight can be turned on normally, and the vacuum motor is turned off to stop the vacuum operation. After the warning light module is installed, the self-resetting knob is in an invalid state, and the vacuum motor cannot be turned on, that is, the vacuum mode cannot be turned on, further preventing the possibility of the vacuum module being turned on when the mode light of the vacuum equipment is in use, thereby reducing safety hazards.

[0020] (5) The fault status module can be used to detect faults in the vacuum cleaner. At the same time, different fault states can be detected according to the color change of the power indicator light, such as a stall fault, a motor battery pack short circuit fault, a charging fault, and a discharging fault. When the fault status module detects that a fault has occurred, the vacuum cleaner can be shut down immediately to reduce the continuous operation of the vacuum cleaner after the fault, thereby reducing the risk of dangerous phenomena.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Embodiment 1: Figure 1-Figure 5The technical scheme shown in the invention provides the following technical scheme: a combined control method for a vacuum cleaner, disclosing: a control and display module, a normal working status module, a charging control module and a fault status module, wherein the control and display module includes a self-reset knob, a host push button and a power indicator light, and the normal working status module can be controlled by the self-reset knob and the host push button, so that the vacuum cleaner body can achieve different working effects according to needs, and the charging control module and the fault status module can be fed back through the changes of the power indicator light. At the same time, the self-reset knob and the host push button are both equipped with a voice prompt system, and the voice prompt system can remind the user to use the control module according to needs, and the normal working status module includes a vacuum cleaner, a vacuum module and a warning light module, and the vacuum motor arranged inside the vacuum cleaner can be started by changing the position state of the self-reset knob, and the vacuum module is installed to the vacuum cleaner. When the vacuum cleaner is outside the machine, the position of the self-reset knob can be adjusted to adjust the state of the vacuum module, so that the vacuum motor can be turned on or off. By changing the position of the host button, the flashlight mode can be selectively turned on according to the needs of the user. At the same time, the warning light module cannot be turned on. When the warning light module is installed on the outside of the vacuum cleaner, the position of the host button can be adjusted to adjust the state of the warning light module. At this time, the self-reset knob is in an invalid state, and the vacuum motor cannot be turned on. When the normal working state module is in use, the color of the battery indicator light can be changed through the normal working state module. When the charging control module is running, the color of the battery indicator light can be changed. At this time, the charging status of the vacuum device body can be fed back through the color change of the battery indicator light. At the same time, when the vacuum device body is in normal charging state, the control key is in an invalid state, that is, the vacuum, warning light and flashlight cannot be turned on.

[0024] When the host push button is not in the middle position, the self-reset knob is in an invalid state, and the vacuum motor is turned off by default to stop vacuuming. Sliding the self-reset knob cannot turn on the vacuum motor. When the host push button is in the middle position, sliding the self-reset knob is effective. When the host push button is in the upper warning light position, the warning light mode is turned on. When the host push button is in the lower flashlight position, the flashlight mode is turned on. At the same time, when the host push button is in the initial state, both the warning light mode and the flashlight mode are turned off. When the resistance is between 5%<RC≤100%, the power indicator light is always green. When the resistance RC≤5%, the power indicator light continues to flash red until 0% and then turns off. The color change of the power indicator light can provide feedback on the power of the module in the normal working state. When 0%≤SoC<100%, the power indicator light continues to flash green. When SoC=100, the power indicator light is always green for 2 minutes and then turns off to enter the shutdown state.

[0025] Through the different color changes of the power indicator light itself, the working status, charging status and fault status of the vacuum cleaner can be fed back, so as to know the usage of the vacuum cleaner. The host push button and the self-reset knob are equipped with pressure sensor components. The pressure sensor component can identify which button the user is pressing to adjust. The pressure sensor component cooperates with the voice control system to remind the staff to use the control module as needed. When the user accidentally touches the host push button to control the vacuum cleaner module after installing the vacuum cleaner module, the voice control system can issue a voice prompt to remind the user of the incorrect use of the button and should use the self-reset knob to control the switch and gear adjustment of the vacuum cleaner. On the contrary, when the user accidentally touches the self-reset knob after assembling the warning light module, the voice control system will synchronously issue a voice prompt to prompt that the button is used incorrectly and the host push button should be used to control the use of the device.

[0026] When the user needs to use the vacuum module, the main unit push button is in the middle state. At this time, slide the self-reset knob to the left to turn on the vacuum mode. After it is turned on, the default standard mode main motor runs at 40W. Slide the self-reset knob to the left again to switch to the strong mode main motor runs at 120W. Slide the self-reset knob to the left three times to turn off the vacuum mode. The vacuum equipment is controlled by the self-reset knob, and the two gears can be adjusted as needed to improve the vacuum effect. At the same time, when the vacuum module is installed, push the main unit push button up so that the main unit push button is in the warning light position, the warning light cannot be turned on, and the vacuum motor is turned off to stop the vacuum operation. Push the main unit push button down so that the main unit push button is in the flashlight position, and the flashlight can be turned on normally. At the same time, the vacuum motor is turned off and the vacuum operation is stopped. After the warning light module is installed, the self-reset knob is in an invalid state, and the vacuum motor cannot be turned on, that is, the vacuum mode cannot be turned on, further preventing the possibility of the vacuum module being turned on when the mode light of the vacuum device is in use, reducing safety hazards. After installing the vacuum module, turn the self-reset knob. At this time, the vacuum device can perform vacuum operations. Since the flashlight module and the suction nozzle are located on both sides of the vacuum device in opposite directions, the main unit push button can only perform vacuum operations when it is in the middle position, reducing the possibility that the vacuum operation is still running when the device is in other use states, and the suction nozzle is aimed at itself, which poses a safety hazard and reduces the possibility of poor user experience.

[0027] Embodiment 2: Figure 1-Figure 5The technical scheme shown in the invention provides the following technical scheme: a combined control method for a vacuum cleaner, which discloses: the fault status module includes a stall fault status module, a motor battery pack short circuit detection module, a charging fault status module and a discharging fault status module; when the motor battery pack short circuit detection module detects a fault, the power indicator light is turned off, and the vacuum cleaner body immediately shuts down; the stall fault status module performs detection operations in the vacuum cleaner mode, and the color change of the power indicator light can provide feedback on a stall fault in the vacuum cleaner, the charging fault status module can detect a charging fault in the vacuum cleaner, and the discharging fault status module can detect a fault that occurs when the vacuum cleaner is working, and the color change of the power indicator light can provide feedback on a discharge fault in the vacuum cleaner body.

[0028] When a stall is detected for 8S, the power indicator light will change state. At this time, the power indicator light flashes green and red alternately for 3 cycles and then goes out. At the same time, the vacuum cleaner enters the shutdown state, and the power indicator light changes color synchronously, thereby reporting that the vacuum cleaner has a charging failure. When a charging failure is caused by overcurrent / overvoltage, the power indicator light flashes red for 10s, and then turns off the light after 10s. The charging failure caused by overcurrent / overvoltage can be known by the change of the power indicator light. After the current / voltage returns to normal, the charger can be plugged in and out to continue charging. If the battery pack detects an overtemperature fault caused by a temperature exceeding 40°C or below 5°C, the charger will be turned off. When a charging failure occurs, the power indicator light remains in its original state, and the vacuum cleaner enters the false charging state. If the battery does not return to normal status within 5 minutes, the light is turned off and the machine is shut down. After the battery pack returns to normal temperature, you can continue charging by plugging in or unplugging the charger. When a discharge failure caused by overtemperature occurs due to the battery pack detection temperature exceeding 40°C or falling below 5°C, the vacuum cleaner immediately stops all operations, the power indicator light flashes red for 10s, and the light is turned off and the machine is shut down after 10s. When the battery pack returns to normal temperature, the machine is turned on again and the vacuum cleaner body can be used normally. When a discharge failure caused by undervoltage occurs, RC≤5%, the power indicator light continues to flash red until 0% and then turns off.

[0029] The fault status module can be used to detect faults in the vacuum cleaner. At the same time, different fault states can be detected according to the color changes of the power indicator light, such as stall fault, motor battery pack short circuit fault, charging fault and discharging fault. When the fault status module detects that a fault has occurred, the vacuum cleaner can be shut down immediately to reduce the continuous operation of the vacuum cleaner after the fault, thereby reducing the occurrence of dangerous phenomena.

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
