Further, the terminal structure 23 of the present embodiment may include two data transmission channels according to actual needs. Each data transmission channel leads out a data transmission pin from the pin end 22, and the data transmission pin is connected with the circuit board 3, so that the oral care device of the embodiment can perform data transmission and reception.

In this embodiment, the shell 212 is sleeved on the mounting base 211 and a preset portion of the pin end 22. Wherein the entire mounting base 211 is located in the shell 212, and the predetermined portion of the pin end 22 and the predetermined portion of the protocol pin 2312 are exposed to the shell 212. In order to improve the protection capability against the terminal structure 23, the housing 212 of the present embodiment is preferably made of a metal material. Wherein, the shell 212 is in snap connection or mortise-and-tenon connection with the mounting base 211, and the shell 212 is generally made of metal. The mounting base 211 is generally made of an insulating material, and the shell 212 and the mounting base 211 can be produced and assembled by a buckle or mortise structure during production, so that the shell 212 and the mounting base 211 have higher connection stability.

Because the oral care device of the present embodiment is used in a water-vapor environment and a water-washing environment, even if the mounting positions of the female connector 2 and the female connector 2 are sealed, the liquid still flows to the protocol pins 2312, the grounding pins 2322 and the grounding pins 2332 through the gap between the shell 212 and the mounting seat 211, and the corroded pins even cause conduction and short circuit between the pins. It is therefore necessary to seal the gap between the housing 212 and the mount 211, or to seal the protocol pins 2312, the power pins 2322, and the ground pins 2332.

In some embodiments, as shown in fig. 6, the oral care device further comprises an potting compound 2132, the potting compound 2132 filling between the walls of the mounting groove 11 and the female socket connector 2 to seal a gap between the mounting groove 11 and the female socket connector 2 and a gap between the shell 212 of the female socket connector 2 and the mounting groove 11. In this way, the filling body 213 can not flow into the body of the oral care device through the gap between the mounting groove 11 and the female connector 2, and the liquid can not flow onto the pins through the gap between the mounting seat 211 and the shell 212, and the filling body 2132 further encapsulates the conductive structure exposed on the mounting seat 211, so as to further prevent the pins from corroding or shorting. Meanwhile, after the gel 2132 is solidified into a solid state, the female connector 2 can be fixed in the mounting groove 11, so that an assembly structure between the female connector 2 and the mounting groove 11 is omitted. By pouring the fluid gel between the mounting groove 11 and the female connector 2, the fluid gel is solidified to form a pouring gel 2132.

Further, the depth of the mounting groove 11 is greater than the length of the female connector 2, that is, the end face of the end where the pin of the female connector 2 is located is lower than the notch of the mounting groove 11, so that the glue filling body 2132 can fully cross the mounting seat 211 of the female connector 2 to wrap, and the waterproof effect of the pin is guaranteed.

In other embodiments, to enhance the waterproof performance of the oral care device, the female housing connector 2 further comprises a seal 213, the seal 213 being disposed at the interface pins 2312, including but not limited to, for waterproof sealing of the interface pins 2312, and further, the seal 213 seals all exposed pins on the mounting housing 211 as well as conductive structures.

The sealing member 213 includes a waterproof jacket 2131, and the waterproof jacket 2131 is sleeved outside the mounting base 211 to seal a gap between the mounting base 211 and the shell 212. Waterproof jacket 2131 can be outside mount pad 211 through injection molding direct injection molding after the mount pad 211 bonding wire finishes, and the wire draws forth in waterproof jacket 2131, so waterproof jacket cladding with all naked conductive structure to and with the clearance cladding between mount pad 211 and the shell 212, guarantee the waterproof effect of pin.

In other embodiments, the sealing element 213 includes a waterproof jacket 2131 and a sealant (not shown in the figures), the waterproof jacket 2131 may be a sleeve-shaped body, and after the wires of the female socket connector 2 pass through the waterproof jacket 2131, the sealant is filled between the mounting socket 211 and the waterproof jacket 2131, so as to realize connection of the waterproof jacket 2131 and the mounting socket 211, and realize sealing between the mounting socket 211 and the shell 212, so as to realize sealing of the exposed conductive structure on the mounting socket.

Illustratively, as shown in fig. 7, waterproof jacket 2131 is sleeved on an end of pin end 22 away from mounting base 211, waterproof jacket 2131 protrudes from a surface of shell 212, so that a first step structure is formed between waterproof jacket 2131 and shell 212. The mounting groove 11 includes a first sub groove 112 and a second sub groove 113 which communicate with each other. Waterproof jacket 2131 is disposed in first subslot 112. The second sub-groove 113 has an opening, one end of the shell 212 is embedded in the waterproof sleeve 2131, a part of the shell 212 located outside the waterproof sleeve 2131 is located in the second sub-groove 113, the second sub-groove 113 is opened at a part of the groove bottom of the first sub-groove 112, so that the groove wall of the first sub-groove 112, the groove bottom of the first sub-groove 112 and the groove wall of the second sub-groove 113 form a second step structure, and the second step structure is matched with the first step structure, thus, in the process of loading the female socket connector 2 into the mounting groove 11 along the direction of pulling out the female socket connector 2 by the male connector, the step surface of the first step structure is abutted to the step surface of the second step structure, and the connection of the female socket connector 2 can be prevented from directly penetrating out of the mounting groove 11. After the assembly is completed, particularly when the male connector is pulled out from the female connector, the male connector can give the female connector 2 a pulling force to be pulled out of the mounting groove 11, and the female connector can be effectively prevented from being pulled out of the mounting groove 11 along with the male connector by abutting the step surface of the first step structure on the step surface of the second step structure.

Optionally, the waterproof jacket 2131 also abuts against the side wall of the first sub-groove 112, such that the waterproof jacket 2131 is limited by the groove wall of the first sub-groove 112.

The female connector 2 having the waterproof jacket 2131 may be mounted in the mounting groove 11 in the same manner as the above-described molding compound 2132. Illustratively, a first gap is formed between waterproof jacket 2131 and the groove wall of first subslot 112; a second gap is formed between waterproof jacket 2131 and the bottom of first sub-groove 112; a third gap is formed between the portion of the shell 212 located outside the waterproof jacket 2131 and the side wall of the second sub-groove 113, and the first gap, the second gap and the third gap are sequentially communicated and are all filled with a glue filling body 2132, wherein the glue filling body 2132 is manufactured through a glue filling process.

In some embodiments, at least one of a guide protrusion and a guide groove is provided on a portion of the case 212 located outside the waterproof jacket 2131, and at least one other of a guide protrusion and a guide groove is formed on a sidewall of the second sub groove 113, the guide protrusion being slidably engaged with the guide groove.
