A switch assembly 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

As shown in fig. 1 to 6, a switch assembly 1 according to an embodiment of the present invention includes a bottom chassis 100, a key paddle 200, a first switch 310, and a second switch 320.

The bottom chassis 100 has a receiving cavity 101, and the receiving cavity 101 has an opening. The key paddle 200 is pivotally mounted at the opening, the key paddle 200 having a first portion 201 and a second portion 202 located on either side of the pivot axis, respectively. A first switch 310 and a second switch 320 are provided within the receiving cavity 101, the first portion 201 being adapted to activate the first switch 310 when depressed and the second portion 202 being adapted to activate the second switch 320 when depressed.

Specifically, when the user presses the first portion 201 of the key paddle 200, the first portion 201 is triggered by the pressing and pivoting of the key paddle 200, and when the user presses the second portion 202 of the key paddle 200, the second portion 202 is triggered by the pressing and pivoting of the key paddle 200, the second switch 320 is triggered by the pressing and pivoting of the key paddle 200.

For example, as shown in fig. 1 to 6, the upper surface of the accommodating chamber 101 is opened to form the opening (the up-down direction is shown by an arrow in the drawings and is merely for convenience of description, and is not a limitation on the actual arrangement direction). This may facilitate the user to operate the switch assembly 1 from above. The key rocker 200 is pivotally mounted at the opening between a reset position, a first position and a second position, the key rocker 200 covers the opening at the reset position, the first portion 201 triggers the first switch 310 and the second portion 202 tilts when the key rocker 200 is at the first position, and the second portion 202 triggers the first switch 310 and the first portion 201 tilts when the key rocker 200 is at the second position. This may facilitate activation of the first switch 310 and the second switch 320 by pivoting of the key paddle 200. Key rocker 200 remains horizontal when in the reset position.

Because the switch of food processing apparatus such as meat grinder among the correlation technique inlays to be established in the guide way, switch button takes place relative slip along with the trend of guide way and guide way when pressing, switch button relies on the guide way to remove to lead to and spacing, easily the guide way inner wall takes place the friction when switch button removes, the user can directly experience the relative slip friction of button and guide way when pressing the button, lead to the user to produce when pressing and pause to contort and feel, lead to feeling relatively poor, influence the travelling comfort when user uses.

According to the switch component 1 of the embodiment of the utility model, the key rocker 200 is arranged in a pivoting manner, and the first switch 310 and the second switch 320 are triggered by the pivoting of the key rocker 200, compared with the technical scheme that the key is guided and limited by the guide groove in the related art, the key rocker 200 takes the pivot axis as a fixed base, the guide groove for guiding and limiting the key is not required to be arranged, and the problem that the key rocker 200 and the guide groove rub against each other to generate pause feeling during pressing is avoided, so that the switch component 1 feels smoother and smoother when a user presses the switch component, and the comfort of the user during use is improved.

As will be understood by those skilled in the art, in some food processing devices of the related art, the keys are made of elastic material, and when a user presses the keys, the corresponding portions of the keys are elastically deformed and move downwards to trigger the micro-switches.

Therefore, on one hand, the keys are made of elastic materials, the requirements on material selection and key manufacturing are higher, the balance of rigidity and elasticity of the materials is not easy to master, the pressing hand feeling is difficult to guarantee, on the other hand, the keys are fatigue due to elastic deformation generated by pressing, and the service life is reduced due to frequent use.

According to the switch component 1, the key rocker 200 is arranged in a pivoting mode, compared with the technical scheme that the keys are made of elastic materials in the related art, the key rocker 200 is not required to be made of the elastic materials and is easy to process and manufacture, the key rocker 200 does not need to deform, the pressing hand feeling is easy to guarantee, fatigue caused by frequent deformation is avoided, and the service life of the switch component 1 is prolonged.

That is to say, the switch assembly 1 realizes the tilting type key structure by arranging the pivotable key tilting plate 200, and compared with the sliding type and elastic type keys, the switch assembly has better hand feeling, simpler processing and manufacturing and longer service life.

Therefore, the switch assembly 1 according to the embodiment of the utility model has the advantages of smooth and fluent hand feeling and the like.
