Along with the sewage gradually enters the sewage tank 7, the sewage overflows the mounting hole 111, so that the inside of the connecting pipe 21 is in a sealed state, the pressure inside the connecting pipe 21 gradually rises, the air pressure rises to cause the film in the air pressure sensor 223 to deform, the ejector pin is driven, the resistance value of the resistor changes, namely, the signal voltage of the air pressure sensor 223 changes until the sewage reaches the highest water level, the signal voltage of the air pressure sensor 223 reaches a preset extreme value, the air pressure sensor 223 transmits a signal to the control system, the control system detects the signal, if the signal is maintained for 5 seconds, the alarm part 222 is indicated to be started, the sewage tank 11 is started to be full of water for indicating, so that the effect of intelligently reminding a consumer is achieved, the situation that the consumer cannot know about the situation to continue using, the electric power and labor waste are caused, and the effect that the consumer experiences are not good is avoided.
The floor cleaning machine comprises an alarm reminding device for clean water, and specifically comprises a water pump 17 and the alarm reminding device, wherein the clean water tank 6 is a detachable clean water tank, the detachable clean water tank 6 is connected to the water inlet end of the water pump 17, a working current detection device is arranged on the water pump 17, and a power supply is provided by a battery pack assembly 9, and the alarm reminding device is connected with the working current detection device.
The working current detection device is an undercurrent relay 51, the triggering threshold value of the undercurrent relay 51 is the no-load working current of the water pump 611, the alarm reminding device comprises a control module 621 and an indication module 622, the undercurrent relay 51 is connected to a signal input interface of the control module 621, and a control signal output end of the control module 621 is connected to a signal input interface of the indication module 622.
The undercurrent relay 51 has high control precision, controllable monitoring range and low cost, and triggers when the current passing through the undercurrent relay 51 is reduced to be lower than the setting value; the no-load current of the water pump 611 is smaller than the load current, so the triggering threshold of the under-current relay 51 can be set according to the no-load current value of the water pump 611. In actual work, when the working current of the water pump 611 is above the threshold value of the undercurrent relay 51, the water pump 611 is in a load working state, the water shortage risk does not exist in the clear water tank, and the subsequent alarm action is not triggered; when the working current of the water pump 611 is lower than the threshold value set by the undercurrent relay 51, the working current of the water pump 611 is reduced because no water flows out of the clean water tank and the clean water tank is in a no-load state, and the clean water tank is in a water-deficient state, so that the undercurrent relay 51 is triggered to perform subsequent alarm actions; when the undercurrent relay 51 is triggered, a signal is output to the control module 621, and then the control signal is output to the indicating module 622, so that the clear water tank is lack of water and is alarmed; instruction module 622 includes signal lamp 623 and sound indicating element 624, and when lack of water in the clear water tank, the low temperature of undercurrent relay 51 triggers instruction module 622 through control module 621 because of the electric current for signal lamp 623 lights, and sound indicating element 624 sends sound warning signal simultaneously, in order to warn the user, is in the state of lacking water in the clear water tank, need to close the water pump and carry out the water tank and dismantle the moisturizing, avoids causing empty load damage to equipment.
The working principle of the whole floor washing machine is as follows:
the floor cleaning machine is placed on a charging seat for charging, the floor cleaning machine control system controls automatic cleaning or manually presses a machine automatic cleaning button to enter an automatic cleaning program, the whole automatic cleaning process lasts for 30 seconds, the whole process is intelligently controlled by the control system, firstly, water in a clear water tank is pumped by a water pump and conveyed to a left water spraying port and a right water spraying port of a cleaning head component through a clear water pipe, the water spraying time in the automatic cleaning process lasts for 15 seconds, a rolling brush motor drives a rolling brush to rotate at a high speed to flap a base cleaning mechanism in the period, the rolling brush is automatically cleaned by continuously spraying water and rotating at a high speed and flapping the cleaning mechanism on the charging seat, sewage and garbage are separated by using centrifugal force generated by the high-speed rotation of the rolling brush, the rolling brush is still rotated at a high speed for 15 seconds to spin-dry and dewater the rolling brush after the water spraying cleaning is finished, and the sewage and the garbage generated in the whole automatic cleaning period are separated into a water collecting tank of the charging seat, then all sewage and rubbish that produce in the self-cleaning process are inhaled into the sewage case through the powerful suction that the high-speed rotation of suction motor subassembly produced, reach the automatic recovery of sewage and rubbish that the round brush self-cleaning produced, do not have any water stain and rubbish in the charging seat or the round brush cavity after the washing is accomplished, the automatic program automatic cutout after the self-cleaning is accomplished and the suggestion is washd and is accomplished, and the back is accomplished to whole process, and the user can take off the sewage case from the floor cleaning machine, clears up the sewage case.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions deviate from the technical solutions of the embodiments of the present invention.
