The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Drawings

Detailed Description
Fig. 1 is a schematic structural view of a cleaner body according to the present invention. As shown in fig. 1, the present invention provides a vacuum cleaner including a cleaner body 100, the cleaner body 100 including a motor for generating suction force and a battery pack for supplying electric power. The vacuum cleaner further comprises a detection unit, a switching unit 110 and a control unit, wherein the control unit is electrically connected with the motor, the battery pack, the detection unit and the switching unit 110.
The switching unit is used for switching the first power gear and the second power gear and generating corresponding first power gear signals and second power gear signals; the detection unit is used for detecting the actual power value of the motor; the control unit is used for receiving the first power level signal, the second power level signal and the actual power value and controlling the motor to be in a non-constant power output state according to the first power level signal; and controlling the motor to be in a constant power output state according to the second power gear signal and the actual power value. Preferably, in order to enable the vacuum cleaner to have a longer working time while having a constant suction force in a second power stage, the actual power value of the second power stage is smaller than the actual power value of the first power stage.
The switching unit 110 may be a push button, a rotary knob or a touch screen, a user selects a required output state of the motor by manipulating the push button, the rotary knob or the touch screen, and the switching unit generates corresponding first and second power level signals and then sends the first and second power level signals to the control unit.
The detection unit comprises a voltage measuring device for measuring the voltage of the motor and a current measuring device for measuring the current of the motor, so that the actual power value of the motor is obtained. And the detection unit sends the actual power value to the control unit after detecting the actual power value of the motor.
After the control unit receives the first power level signal sent by the switching unit 110, the control unit controls the motor to be in a non-constant power output state, at this time, the battery pack directly supplies power to the motor, that is, the control unit does not adjust the electric energy supplied to the motor by the battery pack. The actual power value of the motor decreases with increasing operating time as the electrical energy in the battery pack is consumed.
After the control unit receives the second power level signal sent by the switching unit 110, the control unit controls the motor to be in a constant power output state in combination with the actual power value sent by the detection unit. Specifically, the control unit controls the actual power value of the motor to be maintained at a preset constant power value. Preferably, in order to ensure the suction force and the working time of the dust collector, the constant power value is 10% -90% of the rated power value of the motor.
In order to place the motor in a constant power output state, the control unit may control an actual power value of the motor by controlling a current or voltage supplied to the motor by the battery pack.
In order to adjust the actual power of the motor more conveniently, the motor is preferably a brushless motor, and a power modulation circuit carried by the brushless motor is utilized to facilitate the adjustment of the actual power of the motor by the control unit.
It should be noted that, when the motor is in the constant power output state, the actual power value of the motor may also slightly change, for example, the actual power value of the motor fluctuates up and down in the set power, and preferably, the fluctuation is controlled within 10%.
The operation of the vacuum cleaner of the present invention will be described with reference to specific scenarios.
When a user needs to clean a place with less dust, the motor can be in a constant power output state through the switching unit 110, at this time, the suction force provided by the motor is enough to complete the cleaning work, and because the user makes the motor in the constant power output state and the constant power value is smaller than the rated power value of the motor, the electric energy consumed by the motor is less, the sustainable working time is long, and the suction force is constant, so that the user can clean more places conveniently.
If the user finds the dirt that is difficult to clear up in the cleaning process, for example, when large particles or the dirt adhered to the ground, the motor can be in a non-constant power output state through the switching unit 110, at this moment, the battery pack directly supplies power to the motor, namely, the motor can operate at the current maximum power, and the suction force of the dust collector is improved, so that a better cleaning effect is achieved, and the dirt difficult to clear up is cleared up. In addition, under the non-constant power output state, the actual power value of the motor is reduced along with the increase of the working time, the power consumption is gradually reduced, and the longer working time is ensured.
If the user has disposed the dirt which is difficult to be cleaned, and needs to clean the place containing fine dust, the motor can be operated in the constant power output state again through the switching unit 110.
In summary, the switching unit is arranged to enable the motor of the dust collector to be in the first power stage non-constant power output state and the second power stage constant power output state respectively, so that the dust collector has high suction capability and long working time in the first power stage and constant suction capability in the second power stage, and a user can switch the working state of the motor according to different scenes, thereby meeting the use requirements of the user in different scenes and optimizing the use experience of the user.
