Description

Technical Field

[0001] This utility model relates to the technical field of automatic swimming pool cleaning machines, and in particular to the charging components of automatic swimming pool cleaning machines and the automatic swimming pool cleaning machines themselves. Background Technology

[0002] A pool cleaning machine is a machine that can clean stains and other dirt from the bottom or walls of a pool. To facilitate charging, pool cleaning machines are often equipped with charging components.

[0003] Because automatic pool cleaners operate underwater, their charging ports come into contact with water. When the automatic pool cleaner is retrieved from the water to charge, the charging components are usually quite wet. To prevent the pins and the metal sleeve of the charger plug from oxidizing and rusting during charging, which could lead to decreased charging efficiency or failure to charge, existing automatic pool cleaners are equipped with waterproof caps on their charging components.

[0004] However, even so, since automatic pool cleaners operate underwater, if the pins come into contact with water, it can easily cause short circuits or signal interference during charging. Utility Model Content

[0005] To address the issue mentioned above where existing automatic pool cleaners may experience short circuits or signal interference during underwater operation if the pins come into contact with water, this invention provides a charging component and an automatic pool cleaner.

[0007] The charging component of the automatic pool cleaner includes a pin part, which includes a mounting part and a pin. The mounting part has two or more cavities, and the pin is installed in the cavity. The partition between the cavities is made of insulating material. The mounting part is used to fix the automatic pool cleaner to the outer shell. One end of the pin is used to electrically connect to the battery in the sealed compartment of the automatic pool cleaner.

[0008] By adopting the above technical solution, the pins in different cavities are separated by isolation, which greatly reduces the problem of short circuits or signal confusion caused by charging and improves the safety of charging components.

[0009] Optionally, only one pin may be installed in each cavity.

[0010] By adopting the above technical solution, each pin is independent of the others, which greatly reduces the problem of short circuits or signal confusion caused by charging and improves the safety of the charging components.

[0011] Optionally, the cross-sectional shape of the cavity is D-shaped.

[0012] By adopting the above technical solution, misalignment between the charger plug and the pins can be prevented during the plugging process.

[0013] Optionally, the cross-sectional area of ​​the cavity may vary.

[0014] By adopting the above technical solution, misalignment between the charger plug and pins during the insertion process can be effectively prevented.

[0015] Optionally, a waterproof cap is included, wherein the pin portion is provided with an external thread along its circumferential outer wall, and the inner wall of the waterproof cap is provided with an internal thread that matches the external thread.

[0016] By adopting the above technical solution, a detachable connection is formed between the waterproof cap and the pin part, which makes it easy to screw on the waterproof cap and also easy to remove the waterproof cap for charging.

[0017] Optionally, a sealing ring is included. The outer wall of the insertion pin portion is provided with a groove 1 along its circumferential direction. The sealing ring is sleeved on the groove 1. When the waterproof cap is tightened on the insertion pin portion, the sealing ring is pressed by the groove 2 on the inner wall of the waterproof cap and the groove 1 on the outer wall of the insertion pin portion.

[0018] By adopting the above technical solution, a radial seal is provided between the pin and the waterproof cap to prevent moisture from entering the cavity and contacting the pin, thereby improving the safety of the charging component.

[0019] Optionally, a plug is included. When the automatic pool cleaner is charging, the plug's pins are inserted into the cavity, and the shape of the cross-section of the pins is the same as the shape of the cross-section of the cavity in which they are located, and the areas are equal.

[0020] By adopting the above technical solution, the other end of the pin can be plugged into the charger plug to achieve electrical connection.

[0021] Optionally, the insertion post is provided with a pinhole, the inner diameter of the pinhole of the insertion post is equal to the outer diameter of the insertion pin, and a conductive metal tube is installed on the inner wall of the pinhole.

[0022] By adopting the above technical solution, it is possible to avoid the pins from shaking and coming into contact with the conductive metal tube, thus achieving conductivity between the pins and the charger.
