in the figure, 1 is a vehicle-mounted wireless dust collector, 2 is a charging interface, 3 is a cigarette lighter interface, 4 is a storage battery, 5 is a switch, and 6 is a master control single chip microcomputer.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present invention is a connection structure for connecting a vehicle-mounted wireless dust collector to a cigarette lighter, including a vehicle-mounted wireless dust collector 1, the vehicle-mounted wireless dust collector 1 is provided with a charging interface 2 and a cigarette lighter interface 3, the charging interface 2 is a dc charging interface, the cigarette lighter interface 3 is connected to a motor inside the vehicle-mounted wireless dust collector 1, the charging interface 2 is connected to a storage battery 4, and the storage battery 4 is also connected to the motor; more importantly, a switch 5 is further installed between the cigarette lighter interface 3 and the motor, the switch 5, the charging interface 2 and the cigarette lighter interface 3 are respectively connected to the master control single chip microcomputer 6, and meanwhile, the master control single chip microcomputer 6 is also respectively connected to the positive electrode and the negative electrode of the storage battery 4.

In this embodiment, when wireless dust collector 1 inserts cigar lighter interface 3, detect the output voltage at battery 4 both ends through master control singlechip 6, and judge whether current voltage is greater than the threshold value, thereby break off the switch between battery 4 and the motor, avoid when the cigar lighter plug supplies power to wireless dust collector 1, battery 4 also supplies power to it simultaneously, thereby avoid battery 4 to carry out charge-discharge repeatedly under this kind of condition and shorten battery 4's life, and also can be convenient switch battery 4 and cigar lighter interface to the power supply of wireless dust collector motor through master control singlechip 6, avoid both to supply power to the motor simultaneously and the instantaneous current that causes is great.

According to another embodiment of the present invention, the battery 4 can be a lithium battery, and the lithium battery is installed inside the vehicle-mounted wireless vacuum cleaner 1, and the lithium battery can reduce the overall weight of the vehicle-mounted wireless vacuum cleaner; just as mentioned above, the cigarette lighter socket 3 is used for connecting into a cigarette lighter in a vehicle cab, and therefore the cigarette lighter socket 3 is also connected with a patch cord for connecting the cigarette lighter socket 3 into the vehicle cab through the patch cord.

Further, in this embodiment, the main control single chip microcomputer 6 is used for collecting voltages at two ends of the storage battery 4, and when the current voltage is smaller than a threshold value, the switch 5 between the storage battery 4 and the motor is turned off; the main control single chip microcomputer 6 is also used for switching the connection or disconnection state between the cigarette lighter interface 3 and the motor and between the storage battery 4 and the motor; thereby realizing the power supply isolation of the storage battery and the cigarette lighter, and even cutting off the switch 5 when the storage battery and the cigarette lighter supply power to the motor at the same time, so as to protect the storage battery from being damaged.

In other words, the structure judges whether the cigarette lighter is plugged under the condition that the battery normally discharges by detecting the voltage change of the battery, and simultaneously, when the battery supplies power and does not have current output, the output is closed in the shortest time so as to reduce the possibility that the cigarette lighter and the battery supply power simultaneously.

It should be noted that, the utility model discloses a connection structure of circuit between the motor of main control singlechip access battery and on-vehicle wireless dust collector is requested protection to the function that non-main control singlechip realized, the technical staff in the field can judge the algorithm through predetermineeing the threshold value with the help of the threshold value commonly used in the field completely, and mode such as micro-control output realizes foretell function, so open and close to main control singlechip control switch, and switch specific function no longer detailed description of cigar lighter and battery powered, the utility model discloses a purpose also is not here.
