Figure 3 As shown in FIG. 1 to FIG. 3, the energy supplement seat 200 comprises an insertion end 2, an insertion position 5, a first electrode 21, a second electrode 22, a first contact 51, a second contact 52, a first magnetic attraction member 4, a second magnetic attraction member 5, a first contact surface 211, and a second contact surface 221. Figure 6 As shown in FIG. 1 to FIG. 3, the energy supplement seat 200 comprises an insertion end 2, an insertion position 5, a first electrode 21, a second electrode 22, a first contact 51, a second contact 52, a first magnetic attraction member 4, a second magnetic attraction member 5, a first contact surface 211, and a second contact surface 221.

[0060] Further, the first electrode 21 is a positive electrode, the second electrode 22 is a negative electrode, the first elastic member 7 is a positive elastic member, the first contact 51 is a positive contact, the first contact surface 211 is a positive contact surface, the second elastic member 8 is a negative elastic member, the second contact 52 is a negative contact, and the second contact surface 221 is a negative contact surface. The first elastic member 7 and the second elastic member 8 can be selected from spring pins, spring sheets and the like.

[0061] As shown in FIG. 1 to FIG. 3, the energy supplement seat 200 comprises an insertion end 2, an insertion position 5, a first electrode 21, a second electrode 22, a first contact 51, a second contact 52, a first magnetic attraction member 4, a second magnetic attraction member 5, a first contact surface 211, and a second contact surface 221. Figure 2 As shown in FIG. 1 to FIG. 3, the energy supplement seat 200 comprises an insertion end 2, an insertion position 5, a first electrode 21, a second electrode 22, a first contact 51, a second contact 52, a first magnetic attraction member 4, a second magnetic attraction member 5, a first contact surface 211, and a second contact surface 221. Figure 3 As shown in FIG. 1 to FIG. 3, the energy supplement seat 200 comprises an insertion end 2, an insertion position 5, a first electrode 21, a second electrode 22, a first contact 51, a second contact 52, a first magnetic attraction member 4, a second magnetic attraction member 5, a first contact surface 211, and a second contact surface 221. Figure 6 When the first contact 51 is pressed, the first contact 51 moves from the insertion position 5 into the opening 53, and the first contact 51 is flush with the inner wall of the insertion position 5.

[0062] When the first contact 51 is pressed, the first contact 51 moves from the insertion position 5 into the opening 53, and the first contact 51 is flush with the inner wall of the insertion position 5.

[0063] And / or, when the second contact 52 is pressed, the second contact 52 moves from the insertion site 5 into the opening 53, and the second contact 52 is flush with the inner wall of the insertion site 5.

[0064] The insertion end 2 is inserted into the insertion slot 50, and a certain pressure is applied to the first contact 51 and the second contact 52. When the pressure reaches a certain level, the first contact 51 and the second contact 52 can be elastically displaced away from the insertion end 2 when pressed, ensuring that the first contact surface 211 and the first contact 51, and the second contact surface 221 and the second contact 52, are in close contact, ensuring stable charging.

[0065] Further, the first contact 51 and the second contact 52 are both arc-shaped structures. Compared with sharp or straight contacts, the arc-shaped first contact 51 and the second contact 52 can reduce friction and wear on the insertion end 2 during contact with the insertion end 2, extending the service life of the charging structure. In addition, the arc-shaped first contact 51 and the second contact 52 are more elastic and more reliable in elastic contact.

[0066] Further, the opening 53 provides sufficient space for the first contact 51 and the second contact 52 to move and avoid being pressed from both sides by the insertion end 2 and the inner wall of the insertion slot 50, effectively preventing the first contact 51 and the second contact 52 from being excessively deformed when pressed. On the other hand, for the insertion end 2, the first contact 51 and the second contact 52 can be elastically displaced away from the insertion end 2 when pressed, so that the first contact surface 211 and the first contact 51, and the second contact surface 221 and the second contact 52, are in close contact while the inner wall of the insertion slot 50, the first contact 51 and the second contact 52 do not collectively press the insertion end 2, making it easier and more convenient to insert or remove the insertion end 2 from the insertion slot 50 during charging. In addition, the second contact 52 can be retracted into the opening 53 and flush with the insertion slot 50 when pressed, so that the second contact 52 remains in contact with the second contact surface 221 while not interfering with the rotation of the second contact surface 221 when the insertion end 2 is rotated horizontally, facilitating the horizontal rotation of the insertion end 2. In addition, when the energy storage device 100 is inserted into the insertion slot 50, the outer wall of the insertion end 2 can be in contact with the slot wall of the insertion slot 50, avoiding gaps between the slot wall of the insertion slot 50 and the insertion end 2, preventing other small objects from being inserted into the gaps, and at the same time making the appearance of the charging structure more beautiful.

[0067] Furthermore, as Figure 6 As shown, the charging base 200 also includes a first housing 91, a second housing 92, a counterweight 93, and a PCB board 94. The first housing 91 is fixed above the second housing 92. The first housing 91 and the second housing 92 enclose a mounting cavity 95. The PCB board 94 and the counterweight 93 are disposed in the mounting cavity 95. The PCB board 94 and the counterweight 93 are secured to the first housing 91 or the second housing 92 via fasteners such as clips and screws. The counterweight 93 increases the weight of the charging base 200, making it more stable and less likely to be easily moved or tipped over.

[0068] Based on the above charging structure, the present invention also provides a dental device, which adopts the following technical solution:

[0069] A dental device includes the aforementioned charging structure. The first magnetic element 3 and the second magnetic element 4 can attract each other, allowing the charging component 100 and the charging seat 200 to quickly align and connect when they are close together, without the need for forceful insertion, thus preventing damage to the charging component 100 and the charging seat 200. Furthermore, the magnetic coupling method can increase the force required to separate the charging component 100 and the charging seat 200, preventing the charging component 100 from falling off during charging and improving charging stability.

[0070] Furthermore, the energy-rechargeable component 100 can be a hot gutta-percha cutter or a hot gutta-percha filling instrument. Both the hot gutta-percha cutter and the hot gutta-percha filling instrument are provided with a battery assembly 1. Both the hot gutta-percha cutter and the hot gutta-percha filling instrument can be inserted into the slot 50 for charging and fixing. When filling teeth, dentists often need to use the heat-exchanging gutta-percha cutter and the hot gutta-percha filling instrument to cut back and forth. Therefore, the hot gutta-percha cutter and the hot gutta-percha filling instrument need to be pulled out and inserted into the slot 50 multiple times. The energy-charging component 100 and the energy-charging seat 200 of the present application enable the doctor to insert the hot gutta-percha cutter or the hot gutta-percha filling instrument into the slot 50 without having to align the first contact surface 211 and the second contact surface 221 with the first contact point 51 and the second contact point 52 respectively in advance. When the doctor is concentrating on observing the patient's mouth and filling the tooth, the doctor does not need to face the energy-charging seat 200. The doctor can use peripheral vision or position memory to blindly insert the hot gutta-percha cutter or the hot gutta-percha filling instrument into the slot 50 for charging and fixing. During the operation, the hot gutta-percha cutter or the hot gutta-percha filling instrument can be efficiently charged and stably placed to ensure that the hot gutta-percha cutter or the hot gutta-percha filling instrument can be obtained as soon as possible, thereby improving the doctor's tooth filling efficiency.
