[0002] With the continuous improvement of people's living standards, various small household appliances have also entered the lives of ordinary people. Most small household appliances currently use batteries as a power source, and the batteries are recharged by plugging in an interface.

[0003] As shown in technical proposal 201820971467.4, the positive electrode structure of the charging part of the current charging head adopts a fixed and independently extended installation method. This method can easily cause the protruding positive electrode structure to accidentally touch and cause a short circuit problem. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide a waterproof magnetic charging structure to solve the problem in the prior art that the positive pole structure of the charging part adopts a fixed and independently extended installation method, which is very likely to cause the protruding positive pole structure to accidentally touch and cause a short circuit.

[0005] The utility model provides a waterproof magnetic charging structure, including a charging base assembly and a connector assembly;

[0006] The charging base assembly includes a circuit board, a positive access member and a negative access member. The negative access member is an annular structure. The positive access member is arranged in the middle of the annular structure of the negative access member. One end of the positive access member and the negative access member is arranged on the circuit board, and the other end of the negative access member is arranged at a height greater than the height of the other end of the positive magnetic attraction member.

[0007] The connector assembly is provided with a first contact piece and a second contact piece. The bottom of the first contact piece is arranged lower than the second contact piece. The first contact piece is adapted to the positive input piece, and the negative docking portion abuts against the negative input piece.

[0008] Different from the existing technology, the above technical solution has the following advantages: by setting the height of the positive access component of the power supply end lower than the height of the negative access component, and the negative access component with a ring structure, foreign objects are easily blocked by the negative access component with a ring structure in advance, thereby reducing the probability of short circuit caused by foreign objects, and the negative access component with a ring structure facilitates the charging device, that is, the connector assembly to be connected to the charging seat assembly at any angle, thereby improving the docking efficiency of the charging structure.

[0009] As a preferred embodiment of the present application, the positive access member includes an assembly sleeve, a top connection member, and a reset member. The assembly sleeve is a cylindrical structure. The top connection member is slidably disposed within the cylindrical structure of the assembly sleeve, partially extending from the assembly sleeve. The reset member is disposed within the assembly sleeve, with one end abutting the top connection member, and the top connection member contacts the first contact member. The provision of the assembly sleeve, the top connection member, and the reset member facilitates adaptation of the downward stroke of the first contact member of the connector assembly, facilitating close contact with the positive access member structure.

[0010] As a preferred embodiment of the present application, the bottom of the assembly sleeve is provided with a drainage hole, which is connected to the cylindrical structure of the assembly sleeve. By providing the drainage hole, when water accumulates on the edge above the charging dock connector, the liquid can be drained to the bottom through the drainage hole for disposal.

[0011] As a preferred embodiment of the present application, an isolator is further included, and the isolator is disposed between the positive input member and the negative input member, and between the first contact member and the second contact member. The provision of the isolator facilitates ensuring the relative position and assembly stability between the positive input member and the negative input member, and between the first contact member and the second contact member, thereby preventing the positive input member and the negative input member, and between the first contact member and the second contact member, from contacting each other and causing a short circuit.

[0012] As a preferred embodiment of the present application, the negative input member and the second contact member are magnets. By using magnets as the negative input member and the second contact member, the negative input member and the second contact member can be quickly connected and tightly attached through magnetic force, ensuring the contact stability of the overall charging structure.

[0013] As a preferred embodiment of the present application, the connector assembly further includes a copper sleeve, which is arranged outside the second contact piece. The copper sleeve is provided to facilitate structural protection of the outer side of the second contact piece.

[0014] As a preferred embodiment of the present application, the outer sides of the charging base assembly and the connector assembly are provided with a rubber coating. The rubber coating facilitates sealing and protecting the outer sides of the charging base assembly and the connector assembly, preventing liquid from seeping in and affecting the normal operation of the device.

[0015] As a preferred embodiment of the present application, the charging base assembly further includes a power cord, which is electrically connected to the circuit board.

[0016] As a preferred embodiment of the present application, the first contact member is provided with a docking groove, which is adapted to the positive access member. By providing the docking groove of the first contact member, the contact area is increased during the abutting contact with the positive access member, and the docking process between the positive access member and the first contact member is carried out by relying on the docking groove.

[0017] As a preferred embodiment of the present application, the second contact member is an annular structure. Rongguo also sets the second contact member as an annular structure to facilitate abutment with the negative docking member. BRIEF DESCRIPTION OF THE DRAWINGS

The positive access member 12 is arranged in the middle of the annular structure of the negative access member 13. One end of the positive access member 12 and the negative access member 13 is arranged on the circuit board 11, and the other end of the negative access member 13 is arranged at a height greater than the height of the other end of the positive access member 12.

[0045] The connector assembly 20 is provided with a first contact member 21 and a second contact member 22 .

[0046] According to the above structure, during use of the waterproof magnetic charging structure, when the connector assembly 20 is not connected, the top of the positive contact member 12 is lower than the top of the negative contact member 13. If a foreign object accidentally enters the area where the charging base assembly 10 is located, it will be blocked by the higher annular structure of the negative contact member 13, preventing contact with the positive contact member 12 and the negative contact member 13 and causing a short circuit. During charging, the first contact member of the connector assembly 20 contacts the positive contact member 12, and the second contact member 22 contacts the negative contact member of the annular structure. The charging base assembly 10 charges the electrical appliance connected to the connector assembly 20 through the circuit formed by the circuit board 11, the positive contact member 12, the first contact member 21, the negative contact member 13, and the second contact member 22. By setting the height of the positive access member 12 at the power supply end lower than the height of the negative access member 13, and the negative access member 13 having a ring structure, foreign objects can be easily blocked by the negative access member 13 with the ring structure, thereby reducing the probability of short circuit caused by foreign objects at the high-voltage end of the power supply.
