Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that all directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.

As shown in the figure, a key mechanism, it is including running through the through-hole 11 that sets up in casing 1 one side, the laminating is in the sealing member 3 of through-hole bottom, sealing member 3 and casing connection promptly for seal through-hole 11, wherein the sealing member adopts double-colored mould mode integrated into one piece with the casing, guarantees the sealing performance of through-hole 11 department, wherein sealing member 3 has the elasticity region, the elasticity region can along the axial deformation of through-hole, be equipped with button support piece 12 in the through-hole, button support piece 12 both ends pass through support arm 13 with the pore wall of through-hole is connected, button support piece and support arm and casing integrated into one piece, the last fixed button 2 that is equipped with of button support piece. The button 2 can move relative to the shell along the axial direction of the through hole to apply force to the elastic area of the sealing element, so that the elastic area deforms along the axial direction of the through hole, and the on-off state of the button switch located in the shell is triggered.

In this embodiment, the key supporting member is pressed against the sealing member, so as to reduce the distance between the key supporting member and the sealing member, so that the deformation of the key supporting member when being stressed is completely acted on the sealing member, and further, the elastic area of the sealing member is deformed, so as to trigger the internal button switch.

The width of support arm wherein will want for a short time, utilizes the toughness of the material of casing itself to make this button support piece have certain deformability, and in order to improve its deformability, will the support arm extends to by the pore wall that is located button support piece both ends button support piece's both sides setting, and the length of extension support arm as far as possible sets the support arm to curve shape, can prolong its length in less space for its deformability is better, and it is better to press the effect.

Meanwhile, the thickness of the supporting arm is smaller than that of the key supporting piece, and the deformation capacity of the supporting arm is further improved.

The key supporting piece is provided with a plurality of positioning holes 15, and the bottom of the key is provided with a positioning column 21 matched with the key supporting piece.

In the embodiment, three positioning holes are arranged in the same row or in the same column, and are matched with the positioning columns, so that the keys are fixedly arranged on the key supporting piece, and the positioning columns and the positioning holes are fixed in an interference fit manner, so that the reliability of key fixation is ensured.

The circumference of any one locating hole is provided with a locating boss 14, the bottom of the key is provided with a locating slot 22 matched with the key, and the connection reliability of the locating boss and the locating slot is further improved by utilizing the matching of the locating boss and the locating slot.

The cross section of reference column is the cross, prevents to mould plastics and contracts, influences the cooperation between them.

The utility model also discloses a personal care device adopting the key mechanism, which is a shaver and comprises a shell 1, wherein the key mechanism is arranged on the shell, a circuit board with a switch button is arranged in the shell, and the switch button is positioned on a deformation path of an elastic area of a sealing piece of the key mechanism.

The key mechanism may also be used in other personal care devices such as hair clippers, nose hair clippers, massagers, and the like.

The examples should not be construed as limiting the present invention, but any modifications made based on the spirit of the present invention should be within the scope of protection of the present invention.
