Description

Technical Field

[0001] This utility model belongs to the field of small household cleaning appliances, and specifically relates to a self-cleaning machine for water surfaces. Background Technology

[0002] Most water surface cleaning machines on the market add more sensors and motion systems to achieve better water surface cleaning, thus increasing costs. However, machines propelled by water flow often encounter problems such as only being able to drift in one direction or stopping in one place when there is no water flow, thereby affecting the cleaning efficiency. Utility Model Content

[0003] Purpose of the utility model: This utility model aims to provide an autonomous water surface cleaning machine to solve the problems existing in the prior art. It reduces the manufacturing cost of the water surface cleaning machine, thereby alleviating the user's operating costs, and enables the machine to move autonomously on the water surface, thus improving the efficiency of water surface cleaning.

[0004] Technical Solution: This invention provides a self-cleaning water surface machine. The main body of the machine consists of an upper shell, a lower shell, a trash can, a power unit, and a wireless communication module. A switch plate is also provided on the lower shell. A rotating shaft and a magnet are mounted on the switch plate. A Hall effect sensor is also located at the bottom of the lower shell near the switch plate. The power unit is located at the bottom of the lower shell. The power unit includes a drive motor and an impeller. The wireless communication module controls the forward and reverse rotation of the drive motor by collecting the electrical signals generated by the magnet and the Hall effect sensor. The wireless communication module includes a control program. During the drive motor's movement, if the Hall effect sensor signal is silent for a preset time, the wireless communication module can control the drive motor to move in the opposite direction through the preset control program. The area of ​​the magnet is smaller than the area of ​​the switch plate, and the magnet is square. The magnet is embedded in the switch plate. The silent state time of the Hall effect sensor in the preset control program within the wireless communication module is between fifteen and twenty seconds.

[0005] The self-cleaning water surface machine provided by this utility model can move by driving a motor and impeller when working on the floating water surface. At the same time, the wireless communication module can not only have a signal to connect with other terminals, but also provide motion feedback based on the signal generated by the combination of Hall sensor and magnet. During normal operation, the switch plate will rotate due to the influence of water flow and drive the magnet to move closer to the Hall sensor. The machine can be judged to be in normal operation by the signal generated by Hall sensor and the signal of impeller rotation. When there is only impeller rotation signal and no Hall sensor signal, it is considered to be in a silent state. If the silent state lasts for 15 to 20 seconds, the impeller can be controlled to rotate in reverse so that the machine can continue to work.

[0006] Furthermore, in the aforementioned self-cleaning water surface machine, the rotating shaft is located at the top of the switch plate, with one end of the shaft snapped onto the switch plate and the other end rotatably connected to the lower housing. The rotating shaft and the lower housing are detachably connected.

[0007] Furthermore, the aforementioned self-cleaning water surface machine has an even number of drive motors arranged symmetrically.

[0008] Furthermore, the aforementioned self-cleaning water surface machine has two drive motors. Each drive motor is equipped with a circuit detection structure that performs path detection through contact between water and electrode plates.

[0009] Furthermore, the aforementioned self-cleaning water surface machine also includes a solar panel and a trash can. A solar panel is installed on the upper casing. The trash can has a folded edge and a handle. The front of the trash can (3) also has a movable baffle. A guide ring is provided around the impeller.

[0010] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0011] The overall component structure is not complex, which helps to reduce production costs;

[0012] The addition of a wireless communication module and Hall effect sensors enables remote control and precise monitoring of operating status.

[0013] By sensing the movement of the magnet through a Hall effect sensor, the speed of the drive motor is adjusted to create a speed difference, thereby achieving steering and reversing. Attached Figure Description
