All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention. In the description of the present specification, a particular feature, structure, material, or characteristic described may be combined in any suitable manner in one or more embodiments or examples.
The terminology used in the present invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
The intelligent equipment described by the invention can be garden tools, electric equipment or other automatic equipment with anhydrous protection function; it is within the scope of the present invention that the above described apparatus/tools be able to employ the essence of the technical solutions disclosed below. The invention is particularly suitable for devices with anhydrous protection.
During the working process of the high-pressure cleaning gun, the reciprocating motion of the piston can generate a large amount of heat, and when the water inlet sucks a water source, the heat generated by the piston can be taken away to achieve the effect of cooling the piston; however, when the water inlet is not supplied with water, heat generated by the reciprocating motion of the piston cannot be taken away through the water source, so that the temperature of the piston is increased, and the service life of the piston is reduced or even damaged. In view of the above problems, an object of the present invention is to provide a water-free protection method for an intelligent device, taking a high-pressure cleaning gun as an example, by collecting a bus current of a motor and comparing the bus current with a preset current value, if the bus current values are smaller than the preset current values in a preset time, primarily judging that the intelligent device is likely to enter a water-free stage; and then acquiring an absolute value of the motor voltage, if the absolute value of the motor voltage is larger than a preset voltage value, determining that the intelligent equipment enters a water-free stage, and triggering a water-free protection operation.

Under different working states, when the intelligent equipment enters a water-free state from a water-containing state, the bus current of the motor is reduced differently. Accordingly, the matched preset voltage value or preset current value is also different corresponding to different operation states.

And setting at least one of a preset voltage value or a preset current value matched with the running state according to the running state.
The intelligent device has multiple states including at least one of a start-up state, a standby state, a working state and a shut-down state. Under different working states, the motor of the intelligent equipment has different operation parameters and corresponds to different motor bus currents. Under different working states, when the intelligent equipment enters a water-free state from a water-containing state, the bus current of the motor is reduced differently. Accordingly, the matched preset voltage value or preset current value is also different corresponding to different operation states. For example, when the intelligent device runs with water in the working state 1, the bus current of the motor is 20A, and when the bus current of the motor is 5A under no load, the preset value is set to be corresponding to the voltage difference value under 14A; when the intelligent equipment runs with water in the working state 2, the bus current of the motor is 15A, and when the bus current of the motor is 5A under no load, the preset value is set to be corresponding to the voltage difference value under 9A.
Preferably, the intelligent device further comprises an alarm for executing the alarm operation; the alarm is connected with the processor, and if the processor is detected to trigger the protection operation, the alarm operation is triggered.

The starting stage of the intelligent equipment is eliminated through the combination of the two judging steps, and the whole method is controlled to be used in the operation process of the intelligent equipment. The problem that heat generated by reciprocating motion of a piston in a water-free state is accumulated in a machine body to reduce the service life of the piston and even damage the piston is solved effectively because the high-pressure cleaning gun suddenly enters the water-free state in the working process.
