OBSTACLE DETECTION DEVICE FOR SWIMMING POOL CLEANING MACHINE

The present invention provides an obstacle touching detecting device for a swimming pool cleaner, which includes a main functional portion of the cleaner. The main functional portion of the cleaner includes a cleaner main body, a controller module, and a power-driven actuating device. The controller module and the power-driven actuating device are connected to the cleaner main body. The obstacle touching detecting device of the swimming pool cleaner further comprises a sensor obstacle touching detecting device. The sensor obstacle touching detecting device includes a trigger unit and a sensor detecting module. The trigger unit is connected to the cleaner main body. The sensor detecting module is electrically connected to the controller module. The controller module is electrically connected to the power-driven actuating device. The trigger unit works collaboratively with the sensor detecting module to trigger the sensor detecting module to generate a detection signal. The present invention has the following feats: with the sensor obstacle touching detecting device, an automatic detection is performed when the cleaner touches the wall, and the cleaner is controlled to change the direction automatically, so that the cleaner can automatically change the direction when meeting the wall or other obstacles. The structure is simple and compact, and the swimming pool can be cleaned independently and efficiently.
