Description

Technical Field

[0001] This utility model belongs to the field of vacuum cleaners. Background Technology

[0002] A vacuum cleaner is an electrical appliance used to clean indoor floors by adsorbing and removing dirt and dust. Handheld, portable vacuum cleaners, in particular, are easy to move and use, making it easier to clean various areas of the room. With the advancement of vacuum cleaner technology, modern models are equipped with dust collection stations. When the vacuum cleaner is placed on a station, the station empties the dust and debris stored inside, allowing the vacuum cleaner to detach from the station and clean the floor with an empty dustbin. Once the dustbin in the station is full, it can be emptied completely, eliminating the need for manual emptying of the dustbin after each use, making it much more convenient.

[0003] When the dust collection base station cleans the vacuum cleaner's dustbin, in addition to activating its own dust collection fan, it also activates the vacuum cleaner's suction fan to create an exhaust airflow. This allows the dust and debris in the dustbin to be expelled into the dust collection base station's dust collection box as much as possible. In existing technologies, the dust collection base station and the vacuum cleaner communicate via wireless signal transmission, such as Bluetooth. However, Bluetooth modules are costly to deploy, and when the suction and dust collection fans work together, the magnetic interference generated by the motors can affect the Bluetooth signal, impacting device communication. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a dust collection device.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A vacuum cleaner includes a vacuum cleaner and a dust collection base. The dust collection base has a mounting position for the vacuum cleaner, and the mounting position includes a dust collection box inlet and a charging port. A dust collection box is connected below the dust collection box inlet, and a dust collection fan is connected inside the dust collection box. The vacuum cleaner includes a suction unit, a floor brush head connected to the suction unit, and a power port connected to the charging port. The suction unit includes a suction fan and a dustbin. A drain door at the bottom of the dustbin can be opened to release waste. When the vacuum cleaner is mounted in the mounting position of the dust collection base, the bottom of the dustbin engages with the dust collection box inlet, and the drain door is opened, allowing the dustbin to connect to the dust collection base. Inside the dustbin, a dust-collecting fan draws the waste from the trash can into the dustbin for temporary storage. Simultaneously, the vacuum cleaner's power input port connects to the charging port of the dust collection base station. The dust collection base station is equipped with a charging output switch circuit connected between the charging power supply and the charging port, used to control the conduction of the charging power supply and the charging port to generate a charging communication signal. The vacuum cleaner has a charging detection circuit and a charging control circuit connected to the power input port. The charging detection circuit receives the charging communication signal and sends it to the vacuum cleaner's MCU to control the vacuum cleaner's suction fan to start and stop, or to control the charging control circuit to conduct and charge the vacuum cleaner's internal power supply.

[0007] The charging communication signal includes a frequency signal that controls the start and stop of the exhaust fan and a continuous high-level signal that controls the charging control circuit to conduct; the base station MCU outputs an on / off signal to turn the charging output switch circuit on or off, so that the electrical energy output by the charging power supply forms the frequency signal; the base station MCU continuously outputs an on signal to keep the charging output switch circuit on, so that the electrical energy continuously output by the charging power supply forms the continuous high-level signal.

[0008] The charging output switching circuit includes switching transistors Q2 and Q3; the on / off signal output by the base station MCU is a high / low level signal, which causes switching transistor Q3 to be turned on or off, thereby controlling switching transistor Q2 to be turned on or off.

[0009] The frequency signals include a start-up signal and a stop-down signal for the exhaust fan formed by different frequencies. After the base station MCU sends the start-up signal for the exhaust fan through the charging output switch circuit, it sends the stop-down signal for the exhaust fan through timing control.

[0010] The frequency signal includes a signal to turn on the suction fan. The charging detection circuit receives the signal to turn on the suction fan and transmits it to the vacuum cleaner MCU to start the suction fan. Then, it turns off the suction fan through timing control.

[0011] The charging detection circuit includes a voltage divider circuit and a filter circuit.

[0012] The charging control circuit includes a switching transistor Q20, a switching transistor Q4, and a rectifier diode D20. The switching transistor Q20 is connected to the internal power supply via the rectifier diode D20. After receiving the charging communication signal, the vacuum cleaner MCU controls the switching transistor Q4 to conduct, which in turn causes the switching transistor Q20 to conduct and charge the vacuum cleaner's internal power supply.

[0013] The dust collection base station is also equipped with a detection circuit to identify whether the vacuum cleaner is installed in place. When the detection circuit identifies that the vacuum cleaner is installed in place, it sends an in place signal to the base station MCU, and the base station MCU triggers the charging output switch circuit to send a frequency signal.

[0014] The dust collection base station is also equipped with a dust collection button, which is used to turn the dust collection fan on and off and send a dust collection signal to the base station MCU. The base station MCU then triggers the charging output switch circuit to send a frequency signal.

[0015] The beneficial effects of this utility model are as follows: After the vacuum cleaner is placed on the dust collection base station, the drain door of the vacuum cleaner's dustbin is aligned with the dust collection box inlet of the dust collection base station, and the power connection port of the vacuum cleaner is connected to the charging port of the dust collection base station. The connection between the power connection port and the charging port enables the dust collection base station to supply power and charge the vacuum cleaner, and at the same time, it enables the connection and communication between the dust collection base station and the vacuum cleaner. Since the connection and communication are achieved through the original power connection port and charging port, only changes need to be made to the circuit, without the need to add a new communication module, thus reducing costs. Moreover, the physical communication connection is more stable, which is beneficial to the communication between the vacuum cleaner and the dust collection base station. Attached Figure Description

[0020] Figure 4 The circuit diagram of the detection circuit of this utility model is shown in the figure. Detailed Implementation

[0021] Reference Figure 1 , Figure 2A vacuuming device includes a vacuum cleaner 1 and a dust collection base station 2. The dust collection base station 2 has a mounting position for the vacuum cleaner 1. The mounting position has a dust collection box inlet 31 and a charging port. The dust collection box inlet 31 is connected to a dust collection box 3. The dust collection box 3 is connected to a dust collection fan 32. The vacuum cleaner 1 includes a suction host 11, a floor brush head 12 connected to the suction host 11, and a power connection port connected to the charging port. The suction host 11 includes a suction fan 13 and a dustbin 14. The bottom of the dustbin 14 can be opened to release waste through a drain door 15. When the vacuum cleaner 1 is placed in the mounting position of the dust collection base station 2, the bottom of the dustbin 14 is inserted into the dust collection box inlet 31 and the drain door 15 is opened to connect the dustbin 14 to the dust collection box 3. The dust collection fan 32 sucks the waste in the dustbin 14 into the dust collection box 3 for temporary storage. At the same time, the power connection port of the vacuum cleaner 1 is connected to the charging port of the dust collection base station 2.

[0022] like Figure 3 , Figure 4 As shown, the dust collection base station 2 is equipped with a charging output switch circuit 5 connected between the charging power supply and the charging port, used to control the conduction of the charging power supply and the charging port to form a charging communication signal; the vacuum cleaner 1 is equipped with a charging detection circuit 7 and a charging control circuit 6 connected to the power connection port; the charging detection circuit 7 receives the charging communication signal and sends it to the vacuum cleaner MCU to control the vacuum cleaner 1's suction fan 13 to start and stop working or to control the charging control circuit 6 to conduct to charge the vacuum cleaner 1's internal power supply 16. By connecting the power connection port and the charging port, the dust collection base station 2 supplies power and charges the vacuum cleaner 1, while simultaneously enabling communication between the dust collection base station 2 and the vacuum cleaner 1. Since the communication is achieved through the existing power connection port and charging port, only changes need to be made to the circuit, eliminating the need for a new communication module, reducing costs, and providing a more stable physical communication connection, which is beneficial for the communication between the vacuum cleaner 1 and the dust collection base station 2.

[0023] As a preferred embodiment of this utility model, the charging communication signal includes a frequency signal that controls the start and stop of the suction fan 13 and a continuous high-level signal that controls the charging control circuit 6 to conduct; the charging output switch circuit 5 includes a switch transistor Q2 and a switch transistor Q3.

[0024] The base station MCU can switch the output of a conduction / cutoff signal. The conduction / cutoff signal output by the base station MCU is a high / low level signal. The high / low level signal can turn the switching transistor Q3 on or off, thereby controlling the switching transistor Q2 on or off, and thus controlling the charging output switch circuit 5 to turn on or off. When the base station MCU continuously switches the output of the conduction / cutoff signal, causing the charging output switch circuit 5 to repeatedly turn on and off, the electrical energy output by the charging power supply forms a square wave frequency signal with a frequency range of 2Hz-50kHz under the continuous change of on / off state. Different frequency signals represent different signal commands, for example; 2Hz... Z represents the signal to turn on the vacuum cleaner fan, and 4Hz represents the signal to turn off the vacuum cleaner fan. These frequency signals can be used in conjunction with the timing control of the base station MCU or the vacuum cleaner MCU. For example, the base station MCU can send a signal to turn on the vacuum cleaner fan via the charging output switch circuit 5, and then send a signal to turn off the vacuum cleaner fan via timing control, thus controlling the vacuum cleaner fan to turn on and off. Alternatively, the charging detection circuit 7 can receive the signal to turn on the vacuum cleaner fan and transmit it to the vacuum cleaner MCU to start the vacuum cleaner fan 13, and then turn it off via timing control, thus controlling the vacuum cleaner fan to turn on and off. After controlling the vacuum cleaner fan through timing control and frequency commands, the following communication cleaning operation mode is executed:

[0025] After vacuum cleaner 1 is placed on the dust collection base station 2 and installed in place, the drain door 15 is unlocked, and the cleaning of the dustbin 14 of vacuum cleaner 1 begins. 1. The dust collection base station 2 starts the dust collection fan 32 to initially suck up the dust and debris in the dustbin 14. After working for 4 seconds, the dust collection fan 32 is turned off. 2. After a 1-second interval, the dust collection fan 32 is started again, and at the same time, a signal is sent from the charging output switch circuit 5 to the charging detection circuit 7 of vacuum cleaner 1, which in turn starts the suction fan 13. At this time, the suction fan 13 and the dust collection fan 32 generate different suction airflows in the dustbin 14. The collision causes dust and fine debris adhering to the inner wall and corners to be blown up. Then, the suction fan 13 and the dust collection fan 32 work continuously for 3 seconds, after which the suction fan 13 is turned off, and the dust collection fan 32 continues to work for 1 second before turning off. 3. After a 1-second interval, the dust collection fan 32 and the suction fan 13 start up simultaneously again and work continuously for 4 seconds before turning off. 4. After a 1-second interval, the dust collection base station 2 does not start the dust collection fan 32. The suction fan 13 of the communication control vacuum cleaner 1 works alone and reduces its working power. The suction fan 13 continues to work for 4 seconds to complete the cleaning of the trash can 14.

[0026] When the base station MCU continuously outputs a high-level signal, it keeps switching transistors Q3 and Q2 continuously conducting, causing the charging power supply to continuously output electrical energy to form the continuous high-level signal. The charging control circuit 6 includes switching transistors Q20 and Q4, and a rectifier diode D20. Switching transistor Q20 is connected to the internal power supply 16 via rectifier diode D20. After receiving the continuous high-level signal, the vacuum cleaner MCU outputs a high-level signal to turn on switching transistor Q4, which in turn turns on switching transistor Q20 to charge the internal power supply 16 of the vacuum cleaner 1. Currently, the charging operation of the internal power supply 16 can have the following two situations: 1. The vacuum cleaner MCU controls the charging operation of the internal power supply 16 while executing the control of the exhaust motor 13; 2. When the vacuum cleaner MCU is controlling the operation of the exhaust motor 13, it does not control the charging control circuit 6 to conduct, thereby achieving charging protection for the internal power supply and the charging power supply.

[0027] All of the above-mentioned switching transistors can be selected from MOSFETs to control the circuit switching, making the control easier to implement and more efficient.

[0028] As a preferred embodiment, the charging detection circuit 7 includes a voltage divider circuit and a filter circuit. The voltage divider circuit includes resistors R10 and R11. By adjusting the resistance ratio between resistors R10 and R11, the higher charging voltage is reduced to a voltage range that the vacuum cleaner MCU can allow. The signal current is rectified by the filter circuit, and the vacuum cleaner MCU reads the square wave frequency signal sent by the dust collection base station.

[0029] As a preferred option, the dust collection base station 2 is also equipped with a detection circuit 9 to identify whether the vacuum cleaner 1 is installed in place. After the vacuum cleaner 1 is identified as being installed in place, a signal is sent to the base station MCU, and the base station MCU triggers the charging output switch circuit 5 to send a frequency signal. That is, when the vacuum cleaner 1 is placed in the dust collection base station 2, the dust collection work is started immediately.

[0030] As a preferred option, the dust collection base station 2 is also equipped with a dust collection button. Users can manually press the dust collection button to turn the dust collection fan 32 on and off and send a dust collection signal to the base station MCU. The base station MCU then triggers the charging output switch circuit 5 to send a frequency signal to the vacuum cleaner to start the dust collection operation. Especially after the user places the vacuum cleaner 1 on the dust collection base station 2 and the first dust collection operation has been automatically performed, if the user feels that the dustbin of the vacuum cleaner 1 is not clean enough, the user can manually press the dust collection button to perform the dust collection operation again.
