The charging base is provided with a first electrical contact configured to electrically connect to an external power source. The grooming device host is provided with a built-in power supply, and a second electrical contact electrically connected to the built-in power supply. When the first electrical contact contacts the second electrical contact, the elastic mechanism applies elastic adjustment to the first electrical contact or the second electrical contact, thereby establishing an elastic connection between the first electrical contact and the second electrical contact. With the structural configuration described above, the grooming device host operates without needing to connect to the mains power supply. Paired with a charging base for recharging and the elastic adjustment provided by the elastic device, it offers significant user convenience. ## Claims ### Claim 1 A charging structure for a hair grooming device, comprising: a charging base provided with a first electrical contact, wherein the first electrical contact is configured to electrically connect to an external power source; a grooming device host provided with a built-in power supply and a second electrical contact, wherein the second electrical contact is electrically connected to the built-in power supply; and an elastic mechanism, wherein the elastic mechanism is configured to apply elastic adjustment to the first electrical contact or the second electrical contact to establish an elastic connection between the first and second electrical contacts when the first electrical contact contacts the second electrical contact. ### Claim 2 (depends on 1) The charging structure according to claim 1, wherein the elastic mechanism is disposed on the charging base, the elastic mechanism is configured to apply the elastic adjustment to the first electrical contact to establish the elastic connection with the second electrical contact. ### Claim 3 (depends on 2) The charging structure according to claim 2, wherein the charging base comprises a first circuit board disposed on the elastic mechanism, the first electrical contact is arranged on the first circuit board, and the first circuit board is configured to electrically connected to the external power source, thereby enabling electrical connection of the first electrical contact and the external power source. ### Claim 4 (depends on 3) The charging structure according to claim 3, wherein the elastic mechanism comprises a base member and a cover member, the cover member covers and secures the first circuit board to the base member, the cover member defines a first through hole, the first electrical contact protrudes through the first through hole to be exposed outside the cover member. ### Claim 5 (depends on 4) The charging structure according to claim 4, wherein a sidewall of the base member is provided with a snap-fit protrusion, a sidewall of the cover member is provided with a snap-fit aperture, and the snap-fit protrusion interlocks with the snap-fit aperture to connect the base member and the cover member. ### Claim 6 (depends on 4) The charging structure according to claim 4, wherein the elastic mechanism further comprises a spring, the charging base defines an installation cavity, the base member is disposed within the installation cavity, a first end of the spring abuts against the base member, a second end of the spring abuts against a bottom wall of the installation cavity, the installation cavity defines an opening, and the cover member protrudes through the opening to be exposed outside the installation cavity. ### Claim 7 (depends on 6) The charging structure according to claim 6, wherein the base member is provided with a positioning post, and the first end of the spring is sleeved over the positioning post. ### Claim 8 (depends on 6) The charging structure according to claim 6, wherein an inner wall of the opening is provided with a stopper block, an outer wall of the cover member is provided with a stopper slot; and the stopper block is disposed within the stopper slot to limit an elastic adjustment travel of the spring. ### Claim 9 (depends on 8) The charging structure according to claim 8, wherein the grooming device host comprises a second circuit board, the second electrical contact is disposed on the second circuit board, and the second circuit board is electrically connected to the built-in power supply, thereby enabling electrical connection of the second electrical contact and built-in power supply. ### Claim 10 (depends on 9) The charging structure according to claim 9, wherein the grooming device host defines a second through hole, the second electrical contact protrudes through the second through hole to be exposed outside the grooming device host; an annular positioning protrusion is disposed on the grooming device host around a periphery of the second through hole, and the annular positioning protrusion encloses a positioning space having a shape complementary to a shape of the cover member. ### Claim 11 (depends on 4) The charging structure according to claim 4, wherein the grooming device host comprises a second circuit board, the second electrical contact is disposed on the second circuit board, and the second circuit board is electrically connected to the built-in power supply, thereby enabling electrical connection of the second electrical contact and built-in power supply. ### Claim 12 (depends on 11) The charging structure according to claim 11, wherein the grooming device host defines a second through hole, the second electrical contact protrudes through the second through hole to be exposed outside the grooming device host;
