However, if a person carelessly selects the dust collector incorrectly or forgets to select the dust collector, the power of the fan or the working mode of the dust collector is not matched with the specific work, so that the working effect of the dust collector is influenced, and the working head and even the fan can be damaged.

As shown in fig. 3, the first working head includes a load and an identification unit, the second working head includes only a load, and the third working head is a pure mechanical structure and does not include any load and circuit.
Referring to fig. 1, 2 and 3, a vacuum cleaner includes:
a blower fan is arranged on the air inlet of the air conditioner,
the shell at least comprises an air inlet and an air outlet;
the main control unit and the fan are arranged in the shell;
the first working head is connected to the air inlet of the shell;
the main control unit identifies the first working head by detecting the identification unit so as to start a first working mode of the fan for the first working head.

In some embodiments, the identification unit is a delay circuit, and the delay circuit is disposed on the motor main board of the first working head and is connected in series to an electric circuit between the working motor of the first working head and the power supply of the vacuum cleaner, so as to delay the start of the working motor.
FIG. 4 is a circuit diagram of a delay circuit in an embodiment of the present application;
in some embodiments, as shown in fig. 4, the delay circuit includes a fet and an RC charging circuit, and the voltage Vgs between the gate and the source of the fet is controlled by the RC charging circuit.
When the voltage Vgs between the grid electrode and the source electrode of the field effect transistor reaches a set value, the delay circuit is conducted, and the RC charging circuit is set according to different capacitance and resistance values, so that the time for the voltage Vgs between the grid electrode and the source electrode to reach the conducting value of the grid electrode and the source electrode can be controlled to achieve the conducting of the delay circuit after the voltage Vgs between the grid electrode and the source electrode is electrified from two ends of the delay circuit.
In some embodiments, as shown in fig. 4, a diode is connected in parallel across the resistor of the RC charging circuit, and the conduction direction of the diode is opposite to the charging current direction of the RC charging circuit.
The two ends of the resistor of the RC charging circuit are connected with the diodes in parallel, the conducting direction of the diodes is opposite to the charging current direction of the RC charging circuit, the discharging speed of the capacitor can be accelerated after the power is cut off, and preparation is made for next time delay starting.
In some embodiments, as shown in fig. 4, the delay circuit further includes an electrostatic discharge tube, one end of which is connected to the gate of the fet and the other end of which is connected to the power ground.
The electrostatic discharge tube is arranged, one end of the electrostatic discharge tube is connected with the grid of the field effect tube, and the other end of the electrostatic discharge tube is connected with a power ground, so that the electrostatic discharge tube can be used for preventing the grid from being punctured by static electricity generated when the dust collector works.
As shown in fig. 4, in some embodiments, the delay circuit has delay times with different lengths according to different sizes of capacitors in the RC charging circuit, and the main control unit identifies different types of the first working heads according to the difference in the delay times of the delay circuit.
Referring to fig. 4, the specific circuit of the delay circuit includes a half-wave rectifier circuit composed of a diode D4, a resistor R8 and a capacitor C5, which is used for providing a dc voltage to a point a, and dividing the voltage by the resistors R4 and R5 to obtain a point B voltage, which is used as a charging voltage to be supplied to an RC charging circuit composed of a resistor R9 and a capacitor C6. When the voltage at the point C on the capacitor C6 rises to above 2.5V (the high voltage can turn on the U2 transistor, i.e., the turn-on voltage of U2), the transistor built in the U2 turns on, the voltage at the point D is low (the point D is low), the resistors R1 and R3 divide the voltage to obtain the voltage at the point E, the capacitor C2 filters the pulse voltage to the pulsating dc voltage, and the voltage waveform at the point E is as shown in fig. 5. At the moment, the Vgs voltage drop of the P-MOS field effect transistor Q1 is kept at a stable voltage value, and the high-side P-MOS field effect transistor Q1 is conducted, so that the load loop is conducted.
In some embodiments, as shown in fig. 4, one end of the ESD1 is connected to the gate of the fet, and the other end is connected to ground, so as to prevent the gate from being broken down by static electricity generated during operation of the vacuum cleaner.
As shown in fig. 4, in some embodiments, a diode D1 for providing a bleeding loop for the back emf generated when the load is stalled is further provided.
In some embodiments, as shown in fig. 4, the resistors R2 and R7 provide the reference source U2 with the voltage at point a to provide the current for normal operation. The voltage D at the early stage of starting is the voltage at the point A and is high level. When the voltage at the point C (namely the charging voltage at the two ends of the C6) is higher than 2.5V, the point D is at a low level; after the power-on, the C6 is charged by R9, and when the voltage value of C6 exceeds 2.5V (i.e., the on voltage of U2), the pins 1 and 3 of U2 are turned on, and the D point is low. When the level of the point D is pulled down, the P-MOS field effect transistor Q1 is conducted, and the load of the working head, such as a carpet brush motor, is electrified and started.
FIG. 5 is a block diagram of the vacuum cleaner employing the delay circuit according to the embodiment of the present application.
As shown in the figure, the delay circuit shown in fig. 4 is disposed in the first working head, so that the delay of the starting time of the first working head, such as a carpet brush, after power is turned on can be realized, and the main control unit can detect the delay, which is generally 100ms, so as to determine that the brush head connected to the dust collector is the first working head.
The main control unit detects the delay, for example, before and after the time point of the delay duration of 100ms, within a time period of 20ms of 90ms to 110ms, whether the current in the load loop changes from nothing to nothing is detected, if so, the load of the working head is connected in series with the delay duration circuit, and then the working head can be judged to be the working head corresponding to the delay circuit; otherwise, it is stated that the working head is not the working head corresponding to the delay circuit.
For the third working head shown in fig. 3, such as floor brush, bed brush, etc., the working head is a pure mechanical one and does not contain any load and circuit. At this time, the main control unit cannot detect the current of the load loop in the working head, and then the main control unit controls the fan to start working in a third mode, and the third mode can also be used as a default working mode of the dust collector.
In some embodiments, the delay circuit has delay times with different lengths according to different sizes of capacitors in the RC charging circuit, and the main control unit identifies different types of the first working heads according to the difference in the delay times of the delay circuit.
For example, if the delay time of the delay circuit is 200ms or 300ms, the main control unit may determine whether there is a change in the load loop current from none to none in the time periods before and after the delay time point, so as to determine different types of first working heads corresponding to different delay times, thereby starting the working mode of the corresponding type of first working head.
In some embodiments, the identification unit is a conductive loop on the first working head interface and independently connected to the main control unit. When the first working head interface is connected to the air inlet of the shell, the conductive loop independently conducts corresponding circuits in the main control unit, so that the main control unit starts corresponding working modes.
In some embodiments, the conductive loop may be disposed at different positions on the first working head interface, each position corresponding to one type of the first working head. When the main control unit detects the conductive loops at different positions, that is, the conductive loops at different positions enable different circuits in the main control unit to be conducted, the main control unit starts corresponding different working modes.
The conductive loop is, for example, a conducting wire arranged at a determined position at the interface of the first working head and the air inlet of the shell. When the first working head is connected to the air inlet of the shell of the dust collector, after the main control unit of the dust collector powers on the dust collector, the main control unit of the dust collector can detect the current in the lead at a determined position, so that the first working head is determined to be a certain first working head, and the working mode of a fan corresponding to the first working head is started. The position of the lead can be set at any determined position of the first working head interface according to requirements, and the conduction of the lead at different positions detected by the main control unit of the dust collector can correspond to the conduction of a certain specific circuit in the main control unit of the dust collector, so that a certain determined working mode of the fan of the dust collector is selectively started.
