Technical Field

The invention relates to the technical field of electrical equipment, in particular to cleaning equipment and a cleaning method.

Background

At present, people often use the help of cleaning equipment when cleaning the ground. Cleaning devices of the prior art often utilize various liquids to clean the surface of an object.

For example, a floor cleaning machine is suitable for cleaning hard surfaces and weak floors of work areas such as cement, granite, marble, ceramics, slate, tile, PVC, wear-resistant terraces, and the like, as a cleaning device. The cleaning machine is mainly divided into a handheld surface cleaning machine and a driving surface cleaning machine. When the floor cleaning machine is used, the spray head of the floor cleaning machine can spray a large amount of water to wash a cleaning operation area.

However, the cleaning apparatus in the related art cannot determine the timing of the liquid ejection, and a large amount of uneven water stains are likely to remain on the work surface. The existing mechanisms for judging the movement direction of the cleaning equipment are complex in structure, large in occupied space, low in sensitivity and lag in time.

In order to solve the above problems or at least partially solve the above technical problems, in one embodiment of the present application, there is provided a cleaning apparatus including:

the device comprises a body and a driving wheel arranged on the body;

a liquid ejecting device provided on the body, the liquid ejecting device being capable of ejecting liquid;

a controller in communication with the liquid ejection device;

the encoder is coaxially connected with a wheel shaft of the movable wheel and used for judging the motion direction of the movable wheel;

the encoder is in communication connection with the controller, and the controller turns on or off the liquid ejection device according to a judgment result of the encoder.

Embodiments of the present application also provide a cleaning method comprising the steps of:

a judging step: judging the rotation direction of the driving wheel through an encoder;

the implementation steps are as follows: if the rotation of the driving wheel in the first direction is determined, the liquid ejecting device is turned on,

if the rotation of the movable wheel in the second direction is determined, the liquid ejecting device is turned off,

the first direction and the second direction are opposite directions.

Compared with the prior art, the cleaning equipment provided by the embodiment of the application judges the rotating direction of the driving wheel by means of the encoder creatively, and can ensure that the liquid spraying device can spray liquid when the body advances and stops spraying liquid when the body retreats, so that the advancing or retreating of the cleaning equipment and the sprayed liquid are kept consistent, time lag is avoided, and the user satisfaction and the cleaning operation effect are improved.

Alternatively, the encoder includes a rotating body, a slot hole being formed at a center of the rotating body;

The encoder can be directly connected with the wheel shaft by virtue of the slotted hole, so that the structure is simple, and the transmission stability is good.

Further optionally, the encoder further comprises a fixing hook, and the fixing hook fixes the encoder on the body. The stability of the encoder operation can be improved by fixing the position of the encoder relatively.

On the other hand, the liquid ejecting head faces the backward direction of the traveling wheel, and turns on the water pump to eject water when the head moves backward, and turns off the water pump when the head moves forward. The operational stability can be further improved.

Optionally, the cleaning apparatus further comprises a suction opening provided in the body for drawing liquid from the working surface of the cleaning apparatus. The cleaning liquid after cleaning can be sucked out through the suction port, so that the aim of cleaning the working surface is fulfilled, and the working surface is cleaner and tidier.

or the running wheel is a rolling brush, and the encoder is arranged at the non-driving end of the rolling brush;

or the driving wheel is an auxiliary wheel of the cleaning equipment, and the auxiliary wheel is a driven wheel for supporting the cleaning equipment.

When the movable wheel is the rolling brush, the transmission between the movable wheel and the rolling brush is most direct, and the error rate is lowest. When the driving wheel is a rear big wheel of the cleaning equipment, the space beside the rolling brush is not occupied, so that the equipment can be better miniaturized. When the driving wheel is an auxiliary wheel of the cleaning equipment, the driving wheel is less interfered and has a simpler structure.

Optionally, the encoder comprises:

the rotary body is connected with a wheel shaft of the movable wheel and rotates along with the movable wheel, the encoder converts the rotation direction of the rotary body into an electric signal and sends the electric signal to the controller, and the controller judges the direction of the rotation motion of the movable wheel according to the received electric signal.
