Description

Filter usage duration statistics system and vacuum cleaner

[0001] The present application claims priority from the Chinese patent application No. 202410897951.7 filed on July 5, 2024, and entitled "Filter usage duration statistics system and vacuum cleaner", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present disclosure relates to the technical field of vacuum cleaners, and in particular, to a filter usage duration statistics system and a vacuum cleaner. BACKGROUND

[0003] In the use of the vacuum cleaner, most of the dust will enter the dust collector of the vacuum cleaner through the pipeline, but some dust will enter the corners of the vacuum cleaner. To this end, the vacuum cleaner generally places a filter at the air outlet and the like to prevent the dust from being discharged into the air again. If the filter is not cleaned until a long time after using the vacuum cleaner, or is not cleaned at all, the cleaning efficiency of the vacuum cleaner will be greatly reduced, and the vacuum cleaner may even not be able to be used normally. Moreover, the filter that has not been cleaned for a long time will breed a large number of bacteria, which is easy to adversely affect the health of the user.

[0004] Therefore, how to monitor the usage duration of the filter so as to timely remind the user to replace or clean the filter when the filter reaches the service life has become a research hotspot in the field. SUMMARY

[0005] In view of this, the present disclosure provides a filter usage duration statistics system and a vacuum cleaner. The system of the present disclosure can accurately count the usage duration of the filter, so that the filter reaching the service life can be found in time, and the user can replace or clean the filter in time, so as to avoid the risk of the filter breeding bacteria and the like adversely affecting the health of the user.

[0006] According to an aspect of the present disclosure, a filter use time length statistics system is provided, which comprises a first power supply module, a second power supply module, a switch, and a control module. The first end of the control module is connected to the filter, the second end of the control module is connected to the first end of the first power supply module, and the second end of the control module is also connected to the first end of the second power supply module through the switch. When the switch is on, the second end of the control module is connected to the first end of the second power supply module. When the switch is off, the second end of the control module is disconnected from the first end of the second power supply module. The control module is used to record the use time length of the filter and detect the connection state of the filter and the control module. When the filter is connected to the control module and a signal indicating normal operation of the motor is received, the use time length of the filter is increased. When the filter is disconnected from the control module, the use time length of the filter is reset. The first power supply module and the second power supply module are used to supply power to the control module. The first power supply module is also used to supply power to the motor. When the first power supply module stops supplying power to the control module, the switch is in an on state, and the second power supply module starts supplying power to the control module.

[0007] In a possible implementation, the second power supply module comprises a button cell, and the control module comprises an electric storage capacitor and a switch control unit. When the first power supply module stops supplying power to the control module, the control module uses the electric storage capacitor to supply power to the switch control unit, the switch control unit controls the switch to be on, and the second power supply module supplies power to the control module through the switch. When the first power supply module starts supplying power to the control module, the switch control unit controls the switch to be off, and the second power supply module stops supplying power to the control module.

[0008] In a possible implementation, the second power supply module comprises a rechargeable battery, and the control module comprises an electric storage capacitor and a switch control unit. When the first power supply module stops supplying power to the control module, the control module uses the electric storage capacitor to supply power to the switch control unit, the switch control unit controls the switch to be on, and the second power supply module supplies power to the control module through the switch. When the first power supply module starts supplying power to the control module, the switch control unit controls the switch to be off, and the second power supply module stops supplying power to the control module.

[0009] In a possible implementation, the second power supply module comprises a rechargeable battery, the control module comprises an electric storage capacitor and a switch control unit, the second end of the second power supply module is further connected to the second end of the first power supply module, and the control module is further configured to: when the first power supply module stops supplying power to the control module, supply power to the switch control unit using the electric storage capacitor, control the switch to be turned on, and supply power to the control module by the second power supply module through the switch; when the first power supply module starts supplying power to the control module, the first power supply module also charges the second power supply module, and when the second power supply module is fully charged, the switch control unit controls the switch to be turned off.

[0010] In a possible implementation, the second power supply module comprises a rechargeable battery, the second end of the second power supply module is further connected to the second end of the first power supply module, and the control module is further configured to: when the first power supply module supplies power to the control module and the usage time of the filter reaches a first threshold, control the switch to be turned on, and the first power supply module starts charging the second power supply module; when the first power supply module stops supplying power to the control module, the first power supply module also stops charging the second power supply module, and the second power supply module starts supplying power to the control module through the switch; and the control module is further configured to: when the first power supply module starts supplying power to the control module again, control the switch to be turned off.

[0011] In a possible implementation, the second power supply module comprises a rechargeable battery, the second end of the second power supply module is further connected to the second end of the first power supply module, and the control module is further configured to: when the first power supply module supplies power to the control module and the usage time of the filter reaches a first threshold, control the switch to be turned on, and the first power supply module starts charging the second power supply module; when the first power supply module stops supplying power to the control module, the first power supply module also stops charging the second power supply module, and the second power supply module starts supplying power to the control module through the switch; and the control module is further configured to: when the first power supply module starts supplying power to the control module again and the second power supply module is fully charged, control the switch to be turned off.

[0012] In a possible implementation, when the first power supply module supplies power to the control module, the control module continuously detects whether the filter is disconnected from the control module; and when the second power supply module supplies power to the control module, the control module detects whether the filter is disconnected from the control module at a first frequency.

[0013] In a possible implementation, the system further comprises a reminding module connected to a third end of the control module, and the control module is further configured to output a reminding signal to the reminding module when the use time length of the filter reaches a first threshold; and the reminding module is configured to remind a user to replace the filter when the reminding signal is received.

[0014] In a possible implementation, the system further comprises a motor operation detection module connected to a fourth end of the control module, and the motor operation detection module is configured to detect whether the motor is operating normally, and generate a signal indicating that the motor is operating normally and send the signal to the control module when it is detected that the motor is operating normally.

[0015] According to another aspect of the present disclosure, a dust collector is provided, which comprises the system described above.

[0016] The filter use time length statistical system according to the embodiments of the present disclosure comprises a first power supply module, a second power supply module, a switch, and a control module. The first end of the control module is connected to the filter, the second end of the control module is connected to the first power supply module, and the second end of the control module is further connected to the first end of the second power supply module through the switch. When the switch is turned on, the second end of the control module is connected to the first end of the second power supply module. When the switch is turned off, the second end of the control module is disconnected from the first end of the second power supply module. Thus, the on and off of the switch can control the on and off of the control module and the second power supply module. The control module records the use time length of the filter and detects the connection state between the filter and the control module. When the filter is connected to the control module and a signal indicating that the motor is operating normally is received, the use time length of the filter is increased. When the filter is disconnected from the control module, the use time length of the filter is reset to zero. Thus, the system has a filter use time length statistical function. The first power supply module and the second power supply module are used to supply power to the control module. When the first power supply module stops supplying power to the control module, the switch is in the on state. When the second power supply module starts supplying power to the control module, the control module remains in a state of not being powered off. The use time length of the filter recorded by the control module is more accurate. In summary, the system of the present disclosure can accurately record the use time length of the filter, so that the use life of the filter can be found in time, and the user can replace or clean the filter in time to avoid the risk of breeding bacteria in the filter and adversely affecting the health of the user. When the system is applied to a dust collector, the quality of the dust collector can be improved.

[0017] Since the control module is not powered off, the zeroing of the filter use time length can be completed when the first power supply module is powering the control module, or when the first power supply module stops powering the control module, that is, the filter can be replaced or cleaned when the first power supply module is powered on or when the first power supply module is not powered on, thereby expanding the application scenarios of filter replacement and being more user-friendly.

[0025] Various exemplary embodiments, features, and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numbers in the drawings represent the same or similar elements. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

[0026] The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any implementation described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations.

[0027] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following detailed description. Those skilled in the art should understand that the present disclosure can also be implemented without some specific details. In some examples, methods, means, elements and circuits that are well known to those skilled in the art are not described in detail in order to highlight the main idea of the present disclosure.

[0028] FIG. 1 shows an exemplary application scenario of a filter service time statistics system according to an embodiment of the present disclosure.

[0029] As shown in FIG. 1, a filter service time statistics system 100 (hereinafter referred to as system) can be arranged in a vacuum cleaner 10, which can be a vacuum cleaner with a power cord 130. The vacuum cleaner 10 can further include a motor 110 and a filter 120.

[0030] The system can record the service time of the filter. The system can acquire a signal indicating the running state of the motor and can detect the connection state of the filter with the system. The service time of the filter can be updated according to the acquired signal and the detected connection state. When the service time of the filter reaches a preset first threshold, it can be determined that the filter reaches the service life and needs to be replaced or cleaned.

[0031] The system can prompt the user that the filter reaches the service life. The user can replace or clean the filter after receiving the prompt. The user can choose to replace or clean the filter when the power cord is unplugged, or can choose to replace or clean the filter when the power cord is plugged in, which is not limited by the present disclosure. Neither of the two replacement methods affects the accuracy of the service time of the filter recorded by the system.

[0032] FIG. 2 shows a schematic diagram of the structure of a filter service time statistics system according to an embodiment of the present disclosure.

[0033] As shown in FIG. 2, in one possible implementation, the system 100 includes a first power supply module 1001, a second power supply module 1002, a switch 1003, and a control module 1004. The first end a1 of the control module 1004 is connected to the filter 120, the second end a2 of the control module 1004 is connected to the first end c1 of the first power supply module 1001, and the second end a2 of the control module 1004 is also connected to the first end d1 of the second power supply module 1002 through the switch 1003,

[0034] When the switch 1003 is turned on, the second end a2 of the control module 1004 is connected to the first end d1 of the second power supply module 1002, and when the switch 1003 is turned off, the second end a2 of the control module 1004 is disconnected from the first end d1 of the second power supply module 1002;

[0035] The control module is configured to record the service time of the filter and detect the connection state of the filter with the control module. When the filter is connected to the control module and a signal indicating normal operation of the motor is received, the service time of the filter is increased. When the filter is disconnected from the control module, the service time of the filter is reset to zero.

[0036] The first power supply module and the second power supply module are configured to supply power to the control module, and the first power supply module is further configured to supply power to the motor. When the first power supply module starts to supply power to the control module, the second power supply module stops supplying power to the control module. When the first power supply module stops supplying power to the control module, the second power supply module starts to supply power to the control module.

[0037] For example, the system can include a first power supply module, a second power supply module, a switch, and a control module. The first power supply module can be configured to supply power to the control module. For example, the first power supply module can include an AC-DC converter and be connected to one end of a power cord. When the other end of the power cord is connected to a socket, the first power supply module can convert AC power input from the power cord into DC power to supply power to the control module. In the following description, the first power supply module is said to be powered on when the power cord is connected to the socket, and the first power supply module is said to be powered off when the power cord is not connected to the socket. The first power supply module can also include a DC power supply to supply power to the control module.

[0038] The system can be arranged in an electronic device, which can be a vacuum cleaner, an air filter, or any other electronic device that requires a filter. The specific type of the electronic device is not limited in the embodiments of the present disclosure. The electronic device further includes a motor, and the usage time of the filter needs to be counted only when the motor is in an operating state.

[0039] The first power supply module is further configured to supply power to the motor. When the motor is a DC motor, the first power supply module can supply DC power to the DC motor. In this case, the first power supply module can include at least a DC power supply, which can reduce the complexity of the circuit of the first power supply module. When the motor is an AC motor, the first power supply module can directly supply AC power to the AC motor. In this case, the first power supply module can include at least an AC-DC converter. The specific implementation of the first power supply module is not limited in the embodiments of the present disclosure.

[0040] The second power supply module can be configured to supply power to the control module. For example, the second power supply module can include a button cell or a rechargeable battery, and the battery included in the second power supply module can generate DC power to supply power to the control module.

[0041] Whether the first power supply module supplies power to the control module and the motor is controlled by a user. A power on / off button and a motor on / off button can be arranged on the vacuum cleaner to control whether the first power supply module starts to work. When the power cord is connected to the socket, the power on / off button is pressed to start the first power supply module to supply power to the control module and the motor, and the motor on / off button is pressed to operate the motor normally. When the motor on / off button is released, the motor stops operating, and when the power on / off button is released, the first power supply module stops working and no longer supplies power to the control module and the motor.

[0042] Whether the second power supply module supplies power to the control module is related to whether the switch is on. When the switch is on, the second power supply module and the control module are also on. If the first power supply module does not supply power to the control module at this time, the second power supply module can supply power to the control module. When the switch is off, the second power supply module and the control module are also off. At this time, whether the first power supply module supplies power to the control module or not, the second power supply module does not supply power to the control module. The on and off of the switch can be controlled by the control module, and an exemplary control mode is given below.

[0043] The switch can be any electronic device that can realize the switching function, such as a triode, a metal oxide semiconductor field effect transistor (MOSFET), an insulated gate bipolar transistor (IGBT), etc. The specific type of the switch is not limited in the present disclosure.

[0044] The purpose of setting the second power supply module is to use the second power supply module to supply power to the control module when the first power supply module does not work, that is, when the first power supply module stops supplying power to the control module, the switch is in the on state, and the second power supply module starts to supply power to the control module, so as to ensure that the control module will not be powered off at any time. In this case, the accuracy of the recorded usage time of the filter by the control module is higher.

[0045] In order to save the electric energy of the second power supply module, the following setting can be further added: when the first power supply module starts to supply power to the control module, the second power supply module stops supplying power to the control module. In this case, the second power supply module consumes less electric energy.

[0046] The control module can include a microcontroller unit (MCU) or other data processing unit, and the specific implementation of the control module is not limited in the embodiments of the present disclosure. As the core of the system, the control module can record the usage time of the filter, detect the connection state of the filter and the control module, and receive signals related to the running state of the motor. Among them, when it is detected that the filter is connected to the control module and the signal indicating that the motor is running normally is received, it can be considered that the filter is also working, and the usage time of the filter can be increased. Exemplarily, when the motor is running normally, the signal indicating that the motor is running normally can be sent to the control module at a preset interval. In the case of detecting that the filter is connected to the control module, the increase of the usage time of the filter can be equal to the preset interval every time the signal indicating that the motor is running normally is received.

[0047] When the filter is disconnected from the control module, it can be considered that the user is ready to replace or clean the filter, and the usage time of the filter installed again needs to be counted again. Therefore, the control module can clear the usage time of the filter.

[0048] In the present disclosure, when the user wants to replace or clean the filter, the filter can be directly removed under the condition that the first power supply module is powered on. In this case, the first power supply module is still working, and when the user removes the filter, the control module detects that the filter is disconnected from the control module, and the control module directly clears the usage time of the filter. In this process, the first power supply module still supplies power to the control module, and the switch does not need to be turned on, and the second power supply module does not need to work. After the user re-installs the filter, the filter is connected to the control module, and the first power supply module continues to supply power to the control module.

[0049] In real life, most users tend to remove the filter under the condition that the first power supply module is powered off. Therefore, the present disclosure also supports removing the filter under the condition that the first power supply module is powered off. The system of the present disclosure can turn on the switch when the first power supply module is not working, and use the second power supply module to supply power to the control module. When the user removes the filter, the control module detects that the filter is disconnected from the control module, and directly clears the usage time of the filter. After the user re-installs the filter, the filter is connected to the control module, and after the first power supply module is powered on, the first power supply module continues to supply power to the control module.

[0050] The filter use time length statistics system according to the embodiment of the present disclosure comprises a first power supply module, a second power supply module, a switch, and a control module. The first end of the control module is connected to the filter, the second end of the control module is connected to the first power supply module, and the second end of the control module is also connected to the first end of the second power supply module through the switch. When the switch is turned on, the second end of the control module is connected to the first end of the second power supply module. When the switch is turned off, the second end of the control module is disconnected from the first end of the second power supply module. The on and off of the switch can control the on and off of the control module and the second power supply module. The control module records the use time length of the filter and detects the connection state of the filter and the control module. When the filter is connected to the control module and a signal indicating normal operation of the motor is received, the use time length of the filter is increased. When the filter is disconnected from the control module, the use time length of the filter is reset to zero. The system has a filter use time length statistics function. The first power supply module and the second power supply module are used to supply power to the control module. When the first power supply module stops supplying power to the control module, the switch is in the on state, and the second power supply module starts supplying power to the control module. The control module remains in a state of not being powered off. The accuracy of the use time length of the filter recorded by the control module is higher. In summary, the system of the present disclosure can accurately record the use time length of the filter, so that the use life of the filter can be found in time, and the user can replace or clean the filter in time to avoid the risk of bacteria breeding in the filter affecting the health of the user. When the system is applied to a dust collector, the quality of the dust collector can be improved.

[0051] Since the control module is not powered off, the resetting of the use time length of the filter can be completed when the first power supply module supplies power to the control module, or when the first power supply module stops supplying power to the control module. That is, the filter can be replaced or cleaned when the first power supply module is powered on, or when the first power supply module is not powered on. The application scenarios for replacing the filter are expanded, which is more user-friendly.

[0052] In a possible implementation, when the first power supply module supplies power to the control module, the control module continuously detects whether the filter is disconnected from the control module.

[0053] When the second power supply module supplies power to the control module, the control module detects whether the filter is disconnected from the control module at a first frequency.

[0054] For example, since the power provided by the first power supply module to the control module comes from outside the system, when the first power supply module supplies power to the control module, the control module can continuously detect whether the filter is disconnected from the control module to improve the real-time performance of the recorded use time length of the filter.

[0055] Since the power provided by the second power supply module to the control module is from inside the system, when the second power supply module supplies power to the control module, the control module can detect whether the filter is disconnected from the control module at the first frequency. The first frequency can be pre-set, and the specific value of the first frequency is not limited in the present disclosure. In this case, the power of the second power supply module can be saved.

[0056] FIG. 3 shows a schematic diagram of the structure of the filter use time length counting system according to an embodiment of the present disclosure.

[0057] As shown in FIG. 3, in a possible implementation, the system 100 further includes a reminding module 1005 connected to the third end a3 of the control module,

[0058] The control module 1004 is further configured to output a reminding signal to the reminding module 1005 when the use time length of the filter 120 reaches the first threshold value.

[0059] The reminding module 1005 is configured to remind the user to replace or clean the filter when the reminding signal is received.

[0060] For example, the system can include a reminding module. The first threshold value can be pre-set, and the first threshold value can be equal to the service life of the filter. The control module records the use time length of the filter, and outputs a reminding signal to the reminding module when the use time length of the filter reaches the first threshold value.

[0061] The reminding module can remind the user to replace or clean the filter when the reminding signal is received. For example, the reminding module can include a buzzer, and the buzzer can emit a sound to remind the user to replace or clean the filter when the reminding signal is received. For another example, the reminding module can include an indicator light, and the indicator light can emit light to remind the user to replace or clean the filter when the reminding signal is received. The specific implementation of the reminding module is not limited in the embodiments of the present disclosure.

[0062] Those skilled in the art should understand that the control module can also remind the user to replace or clean the filter when the system does not include a reminding module. For example, the control module can communicate with a mobile phone, a computer, a smart watch or the like used by the user, and notify the above-mentioned devices that the filter 120 of the dust collector needs to be replaced or cleaned. The embodiments of the present disclosure do not limit whether the system includes a reminding module.

[0063] FIG. 4 shows a schematic diagram of the structure of the filter use time length counting system according to an embodiment of the present disclosure.

[0064] As shown in FIG. 4, in a possible implementation, the system 100 further includes a motor operation detection module 1006 connected to the fourth end a4 of the control module,

[0065] The motor operation detection module 1006 is configured to detect whether the motor is operating normally, and generate a signal indicating that the motor is operating normally and send the signal to the control module 1004 when it is detected that the motor is operating normally.

[0066] For example, the dust collector only sucks dust when the motor is operating normally, and the filter only works when the motor is operating normally. Therefore, a motor operation detection module can be provided in the system to detect whether the motor is operating normally. The motor operation detection module can be connected to the fourth end of the control module. When it is detected that the motor is operating normally, the motor operation detection module generates a signal indicating that the motor is operating normally and sends the signal to the control module.

[0067] If the motor itself integrates the motor operation detection module, the motor can generate a signal indicating that the motor is operating normally by itself. The system can directly receive the signal indicating that the motor is operating normally from the motor, and does not need to additionally provide the motor operation detection module. The disclosure does not limit whether the system includes the motor operation detection module.

[0068] In the embodiments of the disclosure, the second power supply module, the first power supply module, the switch, the reminding module and the motor operation detection module can all be implemented based on the prior art, and the specific structures of the modules and the switch will not be described here.

[0069] The exemplary way in which the control module controls the switch to turn on and off in the system of the disclosure will be described below.

[0070] In a possible implementation, the second power supply module includes a button cell, the control module includes an electric storage capacitor and a switch control unit, and the control module is further configured to,

[0071] When the first power supply module stops supplying power to the control module, the electric storage capacitor supplies power to the switch control unit, the switch control unit controls the switch to turn on, and the second power supply module supplies power to the control module through the switch;

[0072] When the first power supply module starts supplying power to the control module, the switch control unit controls the switch to turn off, and the second power supply module stops supplying power to the control module.

[0073] For example, when the user wants to replace or clean the filter, the user can first control the first power supply module to stop working and remove the filter. At this time, the first power supply module stops supplying power to the control module.

[0074] The control module can include an electric storage capacitor and a switch control unit. When the first power supply module stops supplying power to the control module, the electric storage capacitor can supply power to the switch control unit, the switch control unit can control the switch to turn on, and after the switch turns on, the second power supply module can supply power to the control module.

[0075] The switch control unit can be implemented by a diode or the like. For example, the negative electrode of the diode is connected to the control end of the switch. When it is desired to turn on the switch, a high voltage is provided to the positive electrode of the diode to turn on the diode. The diode outputs a high-level signal to the control end of the switch to turn on the switch. When it is desired to turn off the switch, the voltage provided to the positive electrode of the diode is stopped or a low voltage is provided to the positive electrode of the diode to turn off the diode. The diode outputs a low-level signal to the control end of the switch to turn off the switch. It should be understood by those skilled in the art that the switch control unit can also be implemented by a triode or the like. The specific implementation of the switch control unit is not limited in the present disclosure.

[0076] Compared with the entire control module, the switch control unit consumes very little power. Therefore, even a storage capacitor with small storage capacity can independently provide the power required for the switch control unit to control the switch to be turned on, so that the cost of the control module is low. When the first power supply module or the second power supply module supplies power to the control module, the storage capacitor is charged to ensure that the storage capacitor has sufficient power.

[0077] The second power supply module can include a button cell, and the button cell supplies power. The second power supply module can have a function of monitoring the power of the button cell. When the power of the button cell is lower than a certain threshold, the second power supply module can send a signal indicating that the power of the button cell is low to the control module. The control module can remind the user to replace a new button cell.

[0078] After the filter is installed, the user can control the first power supply module to start working. At this time, the first power supply module starts to supply power to the control module. The first power supply module and the second power supply module can be connected to different pins of the control module. Therefore, the control module can determine which power supply module supplies power to itself according to the pin receiving the voltage signal. When the control module detects that the first power supply module starts to supply power to the control module, the control module can control the switch to be turned off through the switch control unit. At this time, the second power supply module stops supplying power to the control module.

[0079] In this way, when the second power supply module uses a button cell, it can be ensured that the control module does not power off. The button cell has low cost, which can save the cost of the system. Moreover, the button cell has higher safety, which can improve the safety of the system.

[0080] The following describes a first exemplary way in which the control module controls the switch to be turned on and turned off when the second power supply module includes a rechargeable battery.

[0081] In a possible implementation, the second power supply module includes a rechargeable battery, and the control module includes a storage capacitor and a switch control unit. The control module is further configured to,

[0082] When the first power supply module stops supplying power to the control module, the storage capacitor supplies power to the switch control unit, and the switch control unit controls the switch to be turned on, and the second power supply module supplies power to the control module through the switch.

[0083] When the first power supply module starts supplying power to the control module, the switch control unit controls the switch to be turned off, and the second power supply module stops supplying power to the control module.

[0084] For example, the second power supply module can include a rechargeable battery, and the rechargeable battery is powered. The first power supply module can be used to charge the rechargeable battery, or an external power source can be used to charge the rechargeable battery, and the present disclosure does not limit this. For examples in which the first power supply module charges the rechargeable battery, refer to the description of the third exemplary way in which the control module controls the switch to be turned on and turned off below.

[0085] When the user wants to replace or clean the filter, the user can first control the first power supply module to stop working and remove the filter. At this time, the first power supply module stops supplying power to the control module.

[0086] The control module can include a storage capacitor and a switch control unit. When the first power supply module stops supplying power to the control module, the storage capacitor can temporarily supply power to the switch control unit, and the switch control unit controls the switch to be turned on. After the switch is turned on, the second power supply module can supply power to the control module.

[0087] The way in which the storage capacitor supplies power to the switch control unit to finally make the switch be turned on has been described above, and will not be described again here.

[0088] After the filter is installed, the user can control the first power supply module to start working, and at this time, the first power supply module starts supplying power to the control module. The first power supply module and the second power supply module can be connected to different pins of the control module, so that the control module can determine which power supply module is supplying power to itself according to the pin receiving the voltage signal. When the control module detects that the first power supply module starts supplying power to the control module, the switch control unit can control the switch to be turned off, and at this time, the second power supply module stops supplying power to the control module.

[0089] In this way, when the second power supply module uses a rechargeable battery, the control module can be guaranteed not to be powered off. The rechargeable battery does not need to be frequently replaced, and the user experience can be improved.

[0090] The following describes a second exemplary way in which the control module controls the switch to be turned on and turned off when the second power supply module includes a rechargeable battery.

[0091] FIG. 5 shows a schematic diagram of the structure of a filter use duration statistical system according to an embodiment of the present disclosure.

[0092] As shown in FIG. 5, in one possible implementation, the second power supply module 1002 comprises a rechargeable battery, the control module 1004 comprises an electric storage capacitor and a switch control unit, the second end d2 of the second power supply module 1002 is also connected to the second end c2 of the first power supply module 1001, and the control module is further configured to,

[0093] When the first power supply module 1001 stops supplying power to the control module, the switch control unit controls the switch 1003 to be turned on, and the second power supply module 1002 supplies power to the control module through the switch 1003.

[0094] When the first power supply module 1001 starts supplying power to the control module 1004, the first power supply module 1001 also charges the second power supply module 1002, and when the second power supply module 1002 is fully charged, the switch control unit controls the switch to be turned off.

[0095] For example, when the second power supply module comprises a rechargeable battery and the control module comprises an electric storage capacitor and a switch control unit, the manner in which the switch is turned on and the states of the modules after the switch is turned on have been described above and will not be repeated here. The function of the rechargeable battery has been described above and will not be repeated here.

[0096] After the switch is turned on, the second power supply module starts supplying power to the control module and starts consuming the power of the rechargeable battery. After the first power supply module is powered, the first power supply module starts supplying power to the control module, and the first power supply module, the switch, and the second power supply module form a loop, so the first power supply module also charges the second power supply module at the same time. The switch can be kept open first, and at this time the first power supply module will continuously charge the second power supply module.

[0097] The second power supply module can have a function of monitoring the power of the rechargeable battery, and after the power of the rechargeable battery reaches a maximum value, the second power supply module can send a signal to the control module indicating that the power of the rechargeable battery is full. After receiving the signal, the control module controls the switch to be turned off. At this time, the first power supply module still supplies power to the control module, but no longer charges the second power supply module.

[0098] The priority of the first power supply module and the second power supply module can be preset in the control module, and if the first power supply module and the second power supply module are both supplying power to the control module at a certain moment, the first power supply module can be used preferentially to supply power.

[0099] If the first power supply module is powered off during the process in which the switch is turned on and the first power supply module continuously charges the second power supply module, after the first power supply module is powered again, the switch can be controlled to be turned off after the second power supply module is fully charged.

[0100] The control module can control the switch to be turned on or off through the switch control unit. The exemplary implementation has been described above and will not be repeated here.

[0101] In this case, the user does not need to participate, and the second power supply module can be automatically charged, greatly improving the user experience.

[0102] The following describes a third exemplary way in which the control module controls the switch to be turned on or off when the second power supply module includes a rechargeable battery.

[0103] In a possible implementation, the second power supply module includes a rechargeable battery, and the second end of the second power supply module is further connected to the second end of the first power supply module,

[0104] The control module is further configured to control the switch to be turned on when the first power supply module supplies power to the control module and the usage time of the filter reaches the first threshold, and the first power supply module starts to charge the second power supply module.

[0105] When the first power supply module stops supplying power to the control module, the first power supply module also stops charging the second power supply module, and the second power supply module starts to supply power to the control module through the switch.

[0106] The control module is further configured to control the switch to be turned off when the first power supply module starts to supply power to the control module again.

[0107] For example, if the control module does not include a storage capacitor, the control module can only use the external power supply. For the control module, it is unknown whether the first power supply module is turned off before the user removes the filter, and therefore the switch needs to be turned on in advance before the user removes the filter, so that the second power supply module can supply power to the control module in time after the user turns off the first power supply module.

[0108] For example, when the first power supply module supplies power to the control module and the usage time of the filter reaches the first threshold, the control module can determine that the user will soon remove the filter, and at this time, the switch can be controlled to be turned on. At this time, the first power supply module is still powered, and the first power supply module, the switch, and the second power supply module form a loop, so that the first power supply module starts to charge the second power supply module.

[0109] If the user turns off the first power supply module before removing the filter, the second power supply module can directly supply power to the control module. After the user removes the filter and then re-installs the filter, the first power supply module is powered, and the voltage signal received by the control module from the first power supply module through the pin can determine that the first power supply module has started to supply power to itself. The control module can control the switch to be turned off.

[0110] When the first power supply module is working, the control module can control the switch to be turned on every interval of a preset time period, so that the working first power supply module can charge the second power supply module. If the first power supply module continues to supply power to the control module after the switch is turned on, the control module can control the switch to be turned off when the second power supply module is fully charged. If the first power supply module is powered off after the switch is turned on, the control module can control the switch to be turned on again when the first power supply module is charged again and the preset time period is reached, so that the working first power supply module can charge the second power supply module.

[0111] When the chargeable battery is below a certain threshold, the second power supply module can send a signal to the control module indicating that the chargeable battery is low. If the control module receives the signal indicating that the chargeable battery is low and detects that the first power supply module is working, the control module can directly control the switch to be turned on, and the first power supply module can charge the second power supply module. If the control module detects that the first power supply module is not working, the control module can remind the user that the second power supply module needs to be charged. After receiving the reminder, the user can plug the power cord connected to the first power supply module into the socket, and the control module can control the switch to be turned on through the switch control unit when the control module detects that the first power supply module starts to work, so that the first power supply module can charge the second power supply module.

[0112] In this way, when the control module does not include a storage capacitor, the control module can be guaranteed not to be powered off by pre-controlling the switch to be turned on, and the cost of the control module can be reduced.

[0113] The fourth exemplary way in which the control module controls the switch to be turned on and turned off when the second power supply module includes a chargeable battery is described below.

[0114] In one possible implementation, the second power supply module includes a chargeable battery, and the second end of the second power supply module is also connected to the second end of the first power supply module,

[0115] The control module is further configured to control the switch to be turned on when the first power supply module supplies power to the control module and the usage time of the filter reaches a first threshold, and the first power supply module starts to charge the second power supply module.

[0116] When the first power supply module stops supplying power to the control module, the first power supply module also stops charging the second power supply module, and the second power supply module starts to supply power to the control module through the switch.

[0117] The control module is further configured to control the switch to be turned off when the first power supply module starts to supply power to the control module again and the second power supply module is fully charged.

[0118] For example, the second power supply module includes a rechargeable battery, and the switch is turned on in the manner described above without the control module including an electric storage capacitor. The function of the rechargeable battery has been described above and will not be repeated here.

[0119] After the switch is turned on, the second power supply module starts to supply power to the control module and starts to consume the power of the rechargeable battery. When the first power supply module starts to supply power to the control module, the switch can be kept on first, and then the first power supply module starts to charge the second power supply module. When the second power supply module is fully charged, the first power supply module can control the switch to be turned off. In this case, the second power supply module can be fully charged without the assistance of the user, greatly improving the user experience.

[0120] In the case of controlling the switch to be turned on for the purpose of charging the rechargeable battery, even if the user turns off the first power supply module, the switch will still be in the on state, so the state of the switch does not need to be changed. When the first power supply module is powered on again, the switch can still be kept on to charge the second power supply module.

[0121] If the first power supply module is turned off during the process of the switch being turned on and the first power supply module continuously charging the second power supply module, when the first power supply module is powered on again, the switch can be controlled to be turned off after the second power supply module is fully charged.

[0122] Those skilled in the art should understand that, in the case of not including an electric storage capacitor, the control module can still use a switch control unit to control the on and off of the switch. Alternatively, the control module can directly send a high-level signal and a low-level signal to the control end of the switch to control the on and off of the switch. The present disclosure does not limit whether the control module still includes a switch control unit in the case of not including an electric storage capacitor.

[0123] The present disclosure also proposes a dust collector including the filter use time length statistical system described above. The dust collector can also include the motor and the filter described above. The schematic diagram of the structure of the dust collector can be seen in FIG. 1.

[0124] The computer program product of the second aspect can include a computer readable storage medium. The computer readable storage medium can include instructions. The instructions can include one or both of: instructions for causing a computer to enable a user equipment device to receive a configuration message from a base station, the configuration message comprising an indication of a set of one or more parameters for a first type of hybrid automatic repeat request process, the first type of hybrid automatic repeat request process being associated with a first type of data; and instructions for causing a computer to enable a user equipment device to receive a configuration message from a base station, the configuration message comprising an indication of a set of one or more parameters for a first type of hybrid automatic repeat request process, the first type of hybrid automatic repeat request process being associated with a first type of data.

[0125] Embodiments of the present disclosure have been described above, with the understanding that these embodiments are exemplary only, and are not restrictive, and are not limited to the disclosed embodiments. Many modifications and changes to this disclosure would be apparent to those of ordinary skill in the art.
