【Detailed ways】

The technical solutions of the embodiments of the present invention will be explained and described below in conjunction with the accompanying drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the examples in the implementation manners, other examples obtained by those skilled in the art without making creative efforts all belong to the protection scope of the present utility model.

Embodiment one:

Referring to Fig. 1, the mechanical operating device of the cooking utensil proposed by the embodiment of the utility model includes an operating panel 3, a circuit board 1 and a displacement transmission member 4, wherein the circuit board 1 is provided with a key switch 11, and the operating panel 3 is provided with a key switch 11. There is a key 5, and the displacement transmitting member 4 is located between the key switch 11 and the key 5. In actual application, the above-mentioned mechanical operating device also includes a button bracket 2, the interior of the button bracket 2 forms a storage space 23, and the circuit board 1 is fixed in the storage space 23 to protect the circuit board 1; the operation panel 3 is mounted on the button bracket 2. The film on the outer surface is generally made of rubber or polycarbonate, PET and other plastic materials. The above-mentioned button 5 and the operation panel 3 are integrally formed. Pressing the button 5 can cause elastic deformation. 5 can be reset by means of its own material deformation.

The above-mentioned operation panel can also be a hard plastic plate or a metal plate. At the same time, a number of button holes are set on the operation panel. The buttons are installed in the button holes by injection molding or bonding. Material.

The above-mentioned displacement transmission member 4 is columnar, and is located between the key switch 11 and the key 5. When the user presses the key 5, the displacement transmission member 4 transmits the user’s force on the key 5 to the key switch 11, so as to touch the key switch 11. Choose from different functions. In this embodiment, a through hole 20 corresponding to the key 5 is provided at the position where the operation panel 3 is installed on the key bracket 2, and the displacement transmission member 4 is flexibly connected to the wall of the through hole 20. Specifically: referring to FIG. 1, the displacement transmission member A flexible bracket 21 is connected between 4 and the wall of the through hole 20 , the material thickness of the flexible bracket 21 is thinner than that of the button bracket 2 , and the displacement transmission member 4 is connected to the center of the flexible bracket 21 . When the displacement transmission member 4 is pressed by the button, it can drive the flexible support 21 to deform, and after the pressing force is removed, the displacement transmission member 4 is restored to its original position by means of the deformation of the flexible support 21 itself.

From the principle of the mechanical operating device, it can be seen that when the user presses the key 5, the displacement transmission member 4 needs sufficient displacement to touch the key switch 11 on the circuit board 1. If the displacement transmission member 4 cannot touch the key switch 11 after displacement, Then the key response is invalid. For the existing overall convex buttons, the contact area between the finger and the button is small, and the operating feel is not good. If the distance between adjacent buttons is close or the overall area of the button is small, the user's pressing position may deviate from the center of the button, resulting in a button response. Failure or mistriggering of other keys. Referring to FIG. 3 , the button 5 provided in this embodiment includes a pressing portion 52 and a protruding portion 51 surrounding the pressing portion 52 , the pressing portion 52 is connected to the protruding portion 51 , and the protruding portion 51 protrudes away from the displacement transmission member 4 On the operation panel 3 , the pressing portion 52 is recessed toward the direction of the displacement transmission member 4 and corresponds to the displacement transmission member 4 . Specifically: the protruding part 51 protrudes from the upper surface of the operation panel 3, and the pressing part 52 is recessed toward the direction of the displacement transmission part 4. The protruding part 51 ensures that the button 5 has a sufficient amount of deformation and can drive the displacement transmission part 4. Pressing the pressing part 52 can drive the overall deformation of the button 5; but when the button is not pressed, the bottom of the pressing part 52 is higher than the upper surface of the operation panel 3, usually: the concave depth H1 of the pressing part 52 accounts for the protrusion 1/3 to 2/3 of the protruding height H2 of the part 51, that is to say, in this embodiment, the key 5 still protrudes from the upper surface of the operation panel 3 as a whole, but it is different from the prior art in that: this embodiment is still A groove is formed in the middle of the button 5, that is, the pressing portion 52. In order to fit the contour of the finger better, the pressing portion 52 is a concave arc groove.

When the user operates the key, the most direct way is to use the sense of touch to feel the unevenness of the surface of the key. Since the pressing part 52 of this embodiment is inwardly recessed relative to the key as a whole, during the user's operation, the concave-convex pressing The part 52 has a good indication effect for the user, and guides the user's finger to directly touch the pressing part 52 . Since the shape of the pressing part 52 basically matches the outline of the user's finger, the user's finger part can fit well with the pressing part 52 during the user's operation, which increases the contact area between the key and the finger, making it easier to press the key. The discomfort of protruding buttons in the technology improves the operating experience of the product.

In actual application, if the area of the pressing portion 52 is too large, the amount of deformation of the key will be reduced, and if the area of the pressing portion 52 is too small, the effect of guiding the key and the feel of the user will be weakened. In this embodiment, the whole key and the pressing portion 52 are circular, and the diameter D1 of the pressing portion 52 is 1/2 to 1/3 of the diameter D2 of the key, that is, the area of the pressing portion 52 accounts for 1/4 to 1/3 of the total area of the key. 4/9, the same is true for other square, oval and other shaped keys.

For the buttons in the prior art, during operation, the user applies pressure on the top of the button until the top of the button is recessed inward and touches the displacement transmission member, and then continues to apply force until the displacement transmission member touches the key switch on the circuit board At this time, there is generally an indicator light for prompting. However, due to the long stroke of the key, the user's pressing operation may cause the displacement transmission member to not generate enough displacement to touch the key switch, resulting in failure of the key response. In this embodiment, the pressing portion 52 is recessed inwardly relative to the key as a whole, and the distance between the pressing portion 52 and the displacement transmission member 4 is reduced, so that the key can trigger the key switch 11 within a short stroke. The sensitivity of the mechanical operating device is improved, and at the same time, the user's operation is also more labor-saving.

Referring to Fig. 3, the button of this embodiment is convex overall, and the bottom of the pressing part 52 is higher than the upper surface of the operation panel 3 in the unpressed state, so a concave cavity is formed inside the button. In this embodiment, the upper end of the displacement transmission part 4 is extended into the concave cavity to further reduce the distance between the pressing part 52 and the displacement transmission part 4, or the upper end of the displacement transmission part 4 directly contacts the pressing part 52, so that when the user presses the key, the displacement transmission part 4 is directly driven downward. move.

In other embodiments of the present utility model, the upper end of the displacement transmission part 4 can be directly connected to the pressing part 52. In this case, the user can directly drive the displacement transmission part 4 to move downward after pressing the key. At the same time of resetting, the displacement transmission member 4 is driven by the pressing part 52 to return to the initial position.

For the buttons in the prior art, it is also easy to cause the failure of the button response due to the improper pressing position of the button. The reason is that the displacement transmission part under the button usually corresponds to the center of the button (at the top of the convex arc of the button), Due to differences in sensory or tactile sensations during the user's actual operation, the finger pressing position deviates from the center of the button, and the button force at this time may not be able to generate enough travel for the displacement transmission member, and thus cannot trigger the button switch. In this embodiment, the pressing portion 52 is inwardly recessed relative to the button as a whole, and the user can more accurately identify the center position of the button from the senses and touch, so that the button can be pressed at the correct position, so as to reduce the disadvantages in the prior art. The deviation of the position of the finger pressing the key causes the key to fail to be effectively triggered, which improves the success rate of the key operation.
