Drawings

Fig. 1 is a schematic structural view of a light-emitting button for an electrotherapy instrument according to the present invention;

fig. 2 is a schematic structural diagram of another light-emitting button for an electrotherapy instrument according to the present invention.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Example one

Referring to fig. 1, a light-emitting key for electrotherapy instrument, includes circuit board 1, triggers button 2, light-emitting component 3 and button block 4, triggers button 2 and light-emitting component 3 and all locates between circuit board 1 and button block 4, and triggers button 2 and light-emitting component 3 and all is connected with circuit board 1 electricity, is equipped with the printing opacity region on the button block 4.

Optionally, the key cap 4 is a touch panel, the light emitting element 3 is a backlight light emitting plate, and the light emitting element 3 is disposed between the trigger key 2 and the key cap 4.

Optionally, the trigger button 2 is a touch spring or a conductive sponge.

Optionally, a light leakage printing pattern 5 is disposed at a position on the key cap 4 corresponding to the trigger key 2.

In this embodiment, the light-emitting keys are configured as touch light-emitting keys, and when a user touches the touch panel, the trigger keys below the touch panel sense and transmit signals to the circuit board, thereby playing a role of transmitting the key function signals. The circuit board is connected with the luminescent plate electricity that is shaded, circuit board and luminescent plate will switch on when electrotherapy instrument circular telegram, in order to see light out from touch panel, can set up light leak printing figure on touch panel, and each light leak printing figure corresponds a trigger button, the user just so can discern what the function that the button corresponds is, the condition of key or wrong button can not appear obscuring, and the bright light that the button sent also is favorable to improving the button visibility in dark surrounds, more convenience of customers uses.

Example two

Referring to fig. 2, another light-emitting key for an electrotherapy instrument includes a circuit board 1, a trigger key 2, a light-emitting component 3 and a key cap 4, wherein the trigger key 2 and the light-emitting component 3 are both disposed between the circuit board 1 and the key cap 4, the trigger key 2 and the light-emitting component 3 are both electrically connected to the circuit board 1, and the key cap 4 is provided with a light-transmitting region.

Optionally, the key cap 4 is a silica gel surface shell or a plastic surface shell, the light emitting component 3 is an LED lamp, and the light emitting component 3 is disposed on the top of the circuit board 1 and the trigger key 2.

Optionally, the trigger button 2 is a mechanical press button.

Optionally, an electroplated layer 41 for shading is arranged on the outer surface of the key cap 4, the engraved character 6 is arranged at a position on the electroplated layer 41 corresponding to the trigger key, and the engraved depth of the engraved character is the same as the thickness of the electroplated layer.

In this embodiment, the light-emitting key is configured as a mechanical pressing type key, and when a user presses the key cap, the mechanical pressing key below the key cap is also pressed, and at this time, the circuit board receives an electrical signal indicating that the mechanical pressing key is pressed, so as to transmit a function signal of the key. The LED lamp is directly located the circuit board and is pressed the button top with machinery, the LED lamp also can light when the circuit board circular telegram, because silica gel face-piece or plastic face-piece are transparent, consequently, the light of LED lamp can be fully passed through, be unfavorable for discerning the button, consequently, this embodiment sets up the one deck plating coat at button block surface, shelter from the light of LED lamp entirely, the position department sculpture character that corresponds with machinery is pressed to this moment, light just can only be followed from the sculpture character and come out like this, make the discernment of button higher, the degree of depth of carving the character here certainly need be equal to the thickness of plating coat, just so can make light pass through.

Further, can also wholly carry out atomization treatment to the plating layer surface after the sculpture character, can make light more even that the transmission comes out like this, the luminous effect of luminous button is better, can also be further carry out gloss oil to the plating layer surface after the atomization treatment and handle to the character of fine protection sculpture part improves the button visuality.

Optionally, the key cap 4 is made of light-diffusing silica gel or light-diffusing plastic. In the structure, the light diffusion silica gel is formed by adding a light diffusion agent into a silica gel material, and the light diffusion plastic is formed by adding the light diffusion agent into a plastic material; through the structure, the light transmitted by the silica gel surface shell or the plastic surface shell is more uniform when the light source is transmitted.

However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications described in the claims and the specification of the present invention are included in the scope of the present invention. In addition, the abstract and the title are provided for assisting the search of patent documents and are not intended to limit the scope of the present invention.
