Description

Technical Field

[0001] This utility model relates to the technical field of swimming pool cleaning machine accessories, and in particular to an anti-tangling connector for an automatic swimming pool cleaning machine. Background Technology

[0002] An automatic pool cleaner is a cleaning device designed for swimming pool cleaning needs. It can autonomously crawl along the bottom of the pool, circling around and repeatedly cleaning the pool's surface, filtering the water, and collecting debris, leaving the pool water crystal clear. Existing technology includes a towed cable type automatic pool cleaner. When operating underwater or on the surface, one end of the cable is connected to the machine body, and the other end is connected to an external power source on shore. Powered by an external power source, this type of cleaner offers strong cleaning capabilities and can operate at high power for extended periods.

[0003] Because automatic pool cleaners need to move, turn, and climb walls during operation, the cables can become tangled, reducing the distance the machine can reach and decreasing cleaning efficiency. In addition, this tangling increases the number of times the cable is bent, causing the cable insulation to crack and the cable core to be exposed to water, creating a safety hazard.

[0004] Patent publication number CN113745887A discloses a movable connector, including a front column, a rear column, and a rotating mechanism. One end of the front column is screwed to a front nut via a sealing gasket; a slip ring is provided inside the front column, and a rotating mechanism is provided inside the rear column; the rotating mechanism includes a rotating sleeve and a rear clamping cover. This invention uses the rear clamping cover of the rotating mechanism to drive the rotating sleeve to rotate 360°, untangling the twisted wires formed during operation, allowing the cleaning robot to work normally and improving work efficiency. Sealing gaskets are installed at the ends of the front column and rotating sleeve to prevent moisture intrusion, improving safety. A skeleton oil seal is used between the outer wall of the rotating sleeve and the inner wall of the rear column to further prevent mud, dust, and moisture from entering the bearings, extending service life. However, the connection between the stator and the main housing of the slip ring is not stable. After prolonged use, the stator of the slip ring is often in a rotating state, causing the cable between the machine body and the connector to become entangled. This shortens the cleaning area reachable by the automatic pool cleaner, reducing cleaning efficiency. Furthermore, this entanglement increases the number of bends in the cable between the machine body and the connector, leading to insulation rupture and exposing the cable core to water, posing a safety hazard. Utility Model Content

[0005] To improve the unstable connection between the stator and the main housing of the slip ring mentioned above, which often causes the stator of the slip ring to rotate after prolonged use, resulting in entanglement of the cable between the machine body and the connector, the entanglement increases the number of bends in the cable between the machine body and the connector, exposing the cable core to water and causing safety hazards, this utility model provides an anti-entanglement connector for an automatic pool cleaning machine.

[0006] This utility model provides an anti-tangling connector for an automatic swimming pool cleaning machine, using the following technical solution:

[0007] An anti-tangle connector for an automatic pool cleaner includes a cable 1, a cable 2, an electric slip ring, a main housing, and a rotating housing. The main housing has openings 1 and 2 at its two ends. The electric slip ring is installed inside the main housing and includes a stator and a rotor. One end of cable 1 is electrically connected to the stator, and the other end of cable 1 passes through opening 1. The rotating housing is rotatably connected to the main housing, and has openings 3 and 4 at its two ends. One end of cable 2 is electrically connected to the rotor, and cable 2 passes through opening 3. The other end of cable 2 passes through opening 4 of the rotating housing. The connector also includes a reinforcing member. The stator is fixedly mounted on the reinforcing member, and the reinforcing member is fixedly mounted inside the main housing.

[0014] By adopting the above technical solution, it is easier to install the reinforcement components into the interior of the main shell, thus improving installation efficiency.

[0015] Optionally, the main shell includes a first shell and a second shell, which are detachably connected. The slip ring is installed inside the first shell, and the rotating shell is installed inside the second shell, which are rotatably connected.

[0016] By adopting the above technical solution, it is easy to separate shell one and shell two, which facilitates the replacement and maintenance of the slip ring and rotating shell, and reduces maintenance costs.

[0017] Optionally, the positioning protrusion is the outer end face of the shell.

[0018] By adopting the above technical solution, it is easy to position and install the reinforcement onto shell one, and then connect shell one and shell two by thread.

[0019] Optionally, the outer wall of the rotating shell and the inner wall of the cable are rotatably connected by a bearing.

[0020] By adopting the above technical solution, the rotating shell can rotate more smoothly.

[0021] Optionally, the first cable forms a fixed seal between the first opening and the second opening, the second cable forms a fixed seal between the fourth opening and the fourth opening, and an oil seal exists between the rotating shell and the main shell.

[0022] The statement that the cable one forms a fixed seal between the openings means that the cable one is fixedly connected between the openings and forms a seal between the openings.

[0023] The statement that cable two forms a fixed seal between opening four and opening four means that cable two is fixedly connected between opening four and opening four, and cable two forms a seal between opening four and opening four.

[0024] By adopting the above technical solutions, moisture can be prevented from entering the interior of the connector, avoiding leakage of power cord wires due to water, which could lead to electric shock or short circuit tripping, thus improving the safety factor.

[0025] Optionally, the first cable forms a fixed seal between the first opening and the second opening using a PG waterproof connector, and the second cable forms a fixed seal between the fourth opening and the third opening using a PG waterproof connector.

Preferably, the cavity between cable 1 and PG waterproof connector 11 is sealed with glue, and the cavity between cable 2 and PG waterproof connector 11 is also sealed with glue. This further prevents moisture from entering the interior of the connector, avoids water leakage from the power cord conductors leading to electric shock or short circuit tripping, and improves the safety factor.

[0058] The electric slip ring 5 in this application is a conductive slip ring whose main function is to provide electrical energy and signal transmission to the rotating shell 4 during unrestricted continuous rotation. It is also known as a current collector ring, a slip ring, or a rotary electrical joint. The electric slip ring 5 is an electrical component widely used in equipment requiring continuous rotation. It achieves electrical energy and signal transmission through sliding contact, solving problems such as wire entanglement and improving the reliability and stability of the equipment.

[0059] Working principle: After the cleaning robot has been working for a long time, cable 2 is twisted into a spiral shape. One end of cable 1 is electrically connected to stator 51, and one end of cable 2 is electrically connected to rotor 53. The rotating shell 4 and the main shell 3 form a rotatable connection. Cable 2 returns to a straight shape, enabling the cleaning robot to work normally and improving work efficiency.

[0060] During use, the stator 51 is fixedly installed on the reinforcement 6, and the reinforcement 6 is installed inside the main housing 3, thereby strengthening the connection between the stator 51 and the main housing 3.
