DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4The utility model provides a technical solution: a nose hair trimmer shaft connection structure on an electric shaver, comprising a nose hair trimmer bracket bin 2 embedded and fixed on the surface of the shaver 1, a nose hair trimmer assembly 3 is arranged inside the nose hair trimmer bracket bin 2, the nose hair trimmer bracket bin 2 is used to accommodate the nose hair trimmer assembly 3 to achieve the folding of the nose hair trimmer assembly 3, the nose hair trimmer bracket bin 2 and the nose hair trimmer assembly 3 are provided with a conductive rotating connection assembly 4, the conductive rotating connection assembly 4 is used to drive the nose hair trimmer assembly 3 to rotate, and at the same time facilitate the power supply to the nose hair trimmer assembly 3.

[0019] The conductive rotating connection component 4 includes two symmetrically arranged metal shafts A41, and the surfaces of the two metal shafts A41 are both sleeved with sealing rings 42. Metal shafts B43 are arranged on both sides of the nose hair trimmer bracket bin 2, and the surfaces of the two metal shafts B43 are both sleeved with connecting metal terminals 44. The inside of the nose hair trimmer component 3 is provided with motor positive and negative spring pieces 45, which connect the positive and negative poles of the motor inside the nose hair trimmer component 3. The two metal shafts A41 pass through the shaft holes on the surface of the nose hair trimmer component 3 and touch the motor positive and negative spring pieces 45. The sealing ring 42 plays a role of sealing and waterproofing, effectively preventing external moisture from entering the inside of the nose hair trimmer component 3 through the shaft holes, thereby achieving waterproof protection.

[0020] The two metal shafts B43 pass through the nose hair trimmer bracket magazine 2 and penetrate into the metal shaft A41, so that the metal shaft B43 and the metal shaft A41 are connected as a whole, so that the nose hair trimmer assembly 3 can rotate freely around the surface of the metal shaft A41, and connect the metal terminal 44 to the positive and negative spring pieces 45 of the motor to form a circuit conduction, thereby realizing power supply.

[0021] A positioning component 5 is provided between the nose hair trimmer component 3 and the nose hair trimmer support bin 2, and the positioning component 5 is used for providing a positioning reminder for the nose hair trimmer component 3 after rotation.

[0022] The tail of the nose hair trimmer assembly 3 is provided with a mounting groove 51, and a positioning ball 52 is slidably mounted on the inner wall of the mounting groove 51, and an extrusion spring 53 is fixed between the positioning ball 52 and the mounting groove 51. A positioning hole 54 adapted to the positioning ball 52 is opened inside the nose hair trimmer bracket compartment 2. The positioning ball 52 adopts a spherical design, and the positioning hole 54 also adopts a spherical hole design. The arrangement of the extrusion spring 53 facilitates the positioning ball 52 to have a tendency to slide out of the mounting groove 51. When the nose hair trimmer is rotated When the nose hair trimmer assembly 3 is folded, the positioning bead 52 slides against the inner wall of the nose hair trimmer bracket compartment 2 under the action of the elastic force of the squeezing spring 53 until the positioning bead 52 is aligned with the positioning hole 54. Then, the positioning bead 52 is inserted into the positioning hole 54 under the action of the elastic force of the squeezing spring 53. At this time, a sound reminder that the positioning bead 52 is inserted into the positioning hole 54 can be heard. When the nose hair trimmer assembly 3 needs to be folded, the nose hair trimmer assembly 3 is rotated forcefully to make the positioning bead 52 disengage from the positioning hole 54.
