In addition, the large-scale competition swimming pool is provided with a lane line, and the cable can be hung on the card sometimes to influence the normal work of the cleaner.

The main reason for the above disadvantage is that the longer cable is present, if it is eliminated, the above disadvantage can be completely eliminated. If the cable is eliminated, it is impossible to reuse the onshore power supply, and a rechargeable power supply capable of operating in water is necessary to power the automatic swimming pool cleaner.

However, when the charging interface is required to be plugged in and pulled out after the charging is completed, the distance between the electrodes is small in the plugging process, and air between the small distances is extremely easy to break down, so that an arc discharge phenomenon is caused, and the arc discharge can cause irreversible damage to the charging needle and the charging seat coating.

The working process of the floating charging interface structure is as follows:

as shown in fig. 7 and 9, when the first magnetic connection component 1 is in plug connection with the second magnetic connection component 2, since the needle end of the positive charging needle 100 and the needle end of the negative charging needle 101 have a distance difference from the needle end of the detection needle 102, the positive charging needle 100 and the negative charging needle 101 are firstly contacted with the corresponding positive charging seat 200 and the corresponding negative charging seat 201 under the action of the magnetic attraction force, and are centered and positioned, and the positive charging needle 100 and the negative charging needle 101 are firstly fully contacted with the corresponding positive charging seat 200 and the corresponding negative charging seat 201, so that reliable connection is formed;

As shown in fig. 8 and 10, as the attraction force of the magnet continues to act, the detecting needle 102 and the detecting seat 202 will also contact with each other, at this time, the detecting control device 4 detects that the detecting needle 102 is connected with the detecting seat 202, the power supply supplies power to the detecting control device 4, the detecting control device 4 controls the switch assembly 3 to be turned on, so as to form a charging loop, and since the positive charging needle 100 and the negative charging needle 101 are reliably connected with the corresponding positive charging seat 200 and the corresponding negative charging seat 201, the arc discharge phenomenon when the first magnetic connecting assembly 1 is plugged with the second magnetic connecting assembly 2 is avoided;

As shown in fig. 11, when the first magnetic connection assembly 1 and the second magnetic connection assembly 2 are separated from each other, since the length of the positive charging needle 100 and the length of the negative charging needle 101 are longer than the length of the detection needle 102, the detection needle 102 and the detection seat 202 are disconnected first under the action of external force, and the detection control device 4 detects that the detection needle 102 is disconnected, the detection control device 4 controls the switch assembly 3 to be turned off, so as to form an open circuit;

As shown in fig. 12, with the continued action of the external force, the positive charging pin 100, the negative charging pin 101, the corresponding positive charging stand 200, and the negative charging stand 201 are also disconnected, and the charging circuit is already disconnected when the detection pin 102 and the detection stand 202 are disconnected, so that the arc discharge phenomenon when the first magnetic connection assembly 1 is separated from the second magnetic connection assembly 2 is avoided.
