FIG. 2 is an enlarged view of a portion A of FIG. 1 according to the present invention; FIG. 3 is an enlarged view of a portion B of FIG. 1 according to the present invention. As shown in fig. 1 and fig. 2 and fig. 3, the power switching module includes a normally closed switch 201 disposed on the handheld cleaner portion 200, a contact 202 of the normally closed switch 201 is disposed on a combined contact surface of the main body portion 100 and the handheld cleaner portion 200, the main body portion is correspondingly provided with a trigger portion 101, and when the two are combined and connected, the trigger portion 101 contacts the contact 202 to open the normally closed switch 201, so as to cut off a power supply circuit of the second battery pack 210 and the handheld cleaner portion 200.
It should be noted that the present invention is not limited to the manner of triggering the normally closed switch, such as: in addition to the above-described normally closed switch in the form of a mechanical structure, a detection unit may be provided in the hand-held cleaner section 200, and when the detection unit detects that the hand-held cleaner section 200 and the main body section 100 are combined, that is: when the first battery pack 110 is connected to a power supply circuit of the handheld dust collector part 200, the control unit controls the normally closed switch to be switched off, and the first battery pack 110 supplies power to the handheld dust collector part 200; when the detection unit detects that the handheld cleaner portion 200 is separated from the main body portion 100, the control unit controls the normally closed switch to be turned on, and the second battery pack 210 supplies power to the handheld cleaner portion 200.
Wherein, the detection unit includes but is not limited to an optical coupling sensor, a hall sensor, etc. For example: when the detection unit is an optical coupling sensor, the main body part 100 is provided with an excitation lamp, the excitation lamp and the optical coupling sensor are correspondingly arranged, so that when the handheld dust collector part 200 and the main body part 100 are combined, light rays with specific light intensity emitted by the excitation lamp can trigger the optical coupling sensor, the optical coupling sensor sends detection signals to the control unit, the control unit controls the normally closed switch to be switched off after receiving the detection signals of the combination of the handheld dust collector part 200 and the main body part 100, and the first battery pack 110 supplies power to the handheld dust collector part 200; if the handheld vacuum cleaner part 200 is separated from the main body part 100, the optical coupling sensor cannot receive light with specific light intensity, and does not send a detection signal, and when the control unit cannot receive the detection signal of the combination of the handheld vacuum cleaner part 200 and the main body part 100, the control unit controls the normally closed switch to be connected, and the second battery pack 210 supplies power to the handheld vacuum cleaner part 200.
Referring to fig. 3, the power switching module further includes a plug connector 300 respectively and correspondingly disposed on the main body portion 100 and the handheld vacuum cleaner portion 200, where the plug connector 300 is used to connect the first battery pack 110 to a power supply circuit of the handheld vacuum cleaner portion 200. When the handheld dust collector part 200 and the main body part 100 are combined and connected, the first battery pack 110 supplies power to the whole machine through the plug connector 300; when the two are separated, the plug connector 300 is separated, and the first battery pack 110 is disconnected.

As shown in fig. 5, the hand-held cleaner part 200 mainly comprises an airflow generator 220, a second dust-air separator 230 and a second dust bucket 240 which are connected in sequence; and under the action of the airflow generator, the mixed gas is sucked and subjected to gas-solid separation from the second dust-gas separator, the separated solid particles enter the second-stage dust barrel, and the separated gas is discharged.
The second battery pack 210 may be disposed at one side close to the push bar or at the opposite side far from the push bar, as required.
In addition, a control mainboard and a start switch (not shown in the figure) connected with the control mainboard are also arranged on the handheld dust collector part 200, when the whole machine or the handheld dust collector part needs to be used for cleaning, the start switch is closed, the control mainboard enables the power supply circuit of the first battery pack 110 or the second battery pack 210 to be communicated with the airflow generator 220 at the moment, namely, the start switch is closed, so that the airflow generator 220 can start to work, and the multi-power split type dust collector starts to be a main switch of the power supply. For convenience of operation, the start switch can be opened or closed by pressing, rotating, shifting and the like.
It should be noted that, no matter in the working state of the whole machine or the working state of the handheld vacuum cleaner part 200, the first battery pack 110 or the second battery pack 210 both supplies power to the airflow generator 220, and the airflow generator 220 provides airflow in the multi-power split type vacuum cleaner.
In addition, in order to ensure the power supply of the whole machine and lower the center of gravity of the whole machine, the battery capacity of the first battery pack 110 is greater than that of the second battery pack 210; and the first battery pack 110 is disposed at a height lower than that of the second battery pack 210.
For convenience of use, the supply voltages of the first battery pack 110 and the second battery pack 210 may be the same or different, that is: the electrical components of the hand-held cleaner portion 200 (e.g., the airflow generator) may be compatible with a variety of voltages and operate under different voltage conditions. In addition, the invention avoids the mutual influence of the two battery packs during power supply by a mode of independently supplying power to the two battery packs, and can realize the purpose of power supply without additionally arranging an independent battery control unit.
The working process of the present invention is described in detail below with reference to fig. 1 to 5:
the second battery pack 210 of the hand-held cleaner section 200 is connected to the power supply circuit through the above-mentioned normally closed switch 201, and the contact 202 of the normally closed switch 201 is provided on the outer surface of the hand-held cleaner section 200, that is: the contact 202 of the normally closed switch 201 is arranged on the combined contact surface of the main body part 100 and the handheld cleaner part 200. When the handheld dust collector part 200 and the main body part 100 are assembled together, the normally closed switch 201 is pushed open by a structure (for example, a convex structure) correspondingly arranged on the main body part 100 in the process of contacting the two, namely: the connection of the second battery pack 210 to the power supply circuit is cut off, and at this time, the first battery pack 110 is connected to the power supply circuit through the plug connector 300, and after the start switch is closed, the first battery pack 110 starts to supply power to the airflow generator 220. For the same reason, when the user needs to detach the handheld cleaner portion 200 from the whole machine and independently use the handheld cleaner portion 200, the user directly detaches the handheld cleaner portion 200, the combined contact surface of the main body portion 100 and the handheld cleaner portion 200 is separated, and at this time, the plug-in state of the handheld cleaner portion 200 and the main body portion 100 is disconnected, that is: the connection between the first battery pack 110 and the power supply circuit is cut off, the normally closed switch 201 rebounds to the closed state at the moment, the second battery pack 210 is connected to the power supply circuit, after the starting switch is closed, the second battery pack 210 supplies power to the airflow generator 220, and the handheld dust collector part 200 starts to work.
Therefore, the present invention realizes the conversion between the whole set of power supply of the first battery pack 110 and the separate power supply of the second battery pack 210 to the handheld cleaner portion 200 through the above-mentioned specific working process.
The technical solution of the present invention is described in detail below with reference to different use environments and working scenarios.
Scene one
When the area of the area to be cleaned is large or the dust is accumulated more, a long-time and efficient cleaning work needs to be performed, and at this time, the whole machine formed by combining the main body part 100 and the handheld dust collector part 200 can be directly used for performing the dust collection work.
As shown in fig. 1, the working process in this scenario is as follows:
when the starting switch is pressed, the mixed gas enters the multi-power split type dust collector from the floor brush 120, passes through the first dust-gas separator 130, and is subjected to first-stage filtration;
the solid particles filtered by the first stage are accumulated in the first stage dust barrel 140, and the mixed gas with a small amount of residual solid particles continuously enters the second dust-gas separator 230 from the upper part of the first dust-gas separator 130, and is subjected to second stage filtering;
the solid particles filtered by the second stage are accumulated in the second stage dust barrel 240, and the clean gas separated from gas and solid is discharged out of the machine body.
In the working process, the first battery pack 110 completely supplies power to the whole machine, the mixed gas is subjected to two-stage filtration, gas-solid separation is fully performed, and the working efficiency is high and the cleaning is thorough. Because the first battery pack 110 with larger battery capacity is arranged at the lower part of the first dust-gas separator 130 or the first-stage dust barrel 140, the gravity center of the whole machine is lower, the weight of the handle of the whole machine is lightened, and the holding is labor-saving. In addition, since the battery capacity of the first battery pack 110 is relatively large, a large-area and long-time cleaning task can be completed in the complete machine state.
Scene two
When the area to be cleaned is in a position with a small area and a side edge or a higher position like the top of a cabinet, the whole machine cannot be conveniently accessed or lifted. The split type can be adopted at this moment, namely: the hand-held cleaner section 200 is detached from the main body section 100 and used as a stand-alone cleaner, with the second battery pack 210 supplying power independently.
As shown in fig. 3, the working process in this scenario is as follows:
when the start switch is pressed, the mixed gas is sucked and gas-solid separation is performed from the second dust-gas separator 230 under the action of the airflow generator 220, the separated solid particles enter the second-stage dust bucket 240, and the separated gas is discharged.
When the hand-held dust collector part 200 is assembled to the main body part 100 and needs to be reassembled into the whole machine for use after dust collection is finished, the airflow generator 220 of the hand-held dust collector part 200 provides suction to achieve the dust collection function of the whole machine, and at the moment, the first battery pack 110 provides power for the whole machine independently. Since the power of the whole machine during operation is not required to be provided by the second battery pack 210, that is, the second battery pack 210 only needs to provide the power for the handheld vacuum cleaner to partially clean a small area, the capacitance of the second battery pack 210 is smaller than that of the first battery pack 110 in this embodiment.
Scene three
No matter the combined complete machine is adopted to perform dust collection work or the handheld dust collector part 200 is adopted to perform dust collection work alone, when the power of the first battery pack 110 and/or the second battery pack 210 is exhausted, the complete machine can be connected with a charger to complete the charging function of the first battery pack 110 and the second battery pack 210.
As can be seen from the above, the present invention also provides a power supply method for a multi-power split type vacuum cleaner, the multi-power split type vacuum cleaner comprises a main body part 100 and a handheld vacuum cleaner part 200 which are detachably connected, the handheld vacuum cleaner part 200 comprises a second battery pack 210, the main body part 100 comprises a first battery pack 110, and the power supply method comprises: the hand-held cleaner part 200 is separated from the main body part 100, and the second battery pack 210 supplies power to the hand-held cleaner part 200; the hand-held cleaner part 200 and the main body part 100 are combined into a whole, the second battery pack 210 is powered off, and the first battery pack 110 supplies power to the whole.
In conclusion, the multi-power split type dust collector and the power supply method thereof provided by the invention realize that the weight of the handheld dust collector part is greatly reduced, the use feeling is light, the weight is lower when the handheld dust collector is used as a whole machine, the weight at the handle of the whole machine is lightened, and the holding is labor-saving.
