Description

Technical Field

[0001] This utility model belongs to the field of juicers, specifically relating to a waterproof button structure for a juicer. Background Technology

[0002] Traditional waterproofing of buttons uses a mold-coating process combining soft and hard rubber, but this is costly and complex. Using pure silicone buttons, which rely entirely on the deformation of the silicone to trigger the button, requires a large space and has more dead zones, necessitating precise pressure on a specific area to activate the button. Utility Model Content

[0003] The purpose of this invention is to provide a waterproof button structure for a juicer that is low in cost and has a good tactile feel.

[0004] The above objectives are achieved in this way.

[0005] A waterproof button structure for a juicer includes a base, a button cap, a button bracket, and a control board. The base has a receiving cavity with a button opening and a lower opening. A retaining edge is provided at the button opening. The button cap, button bracket, and control board are sequentially installed into the container cavity from the lower opening. The button cap extends outward from the button opening. When the control board is fastened in the receiving cavity, the control board presses upward against the button bracket, causing the retaining edge and the button cap to fit tightly together.

[0006] The button bracket is equipped with a trigger post, the two ends of which abut against the keycap and the control board respectively. When the keycap is pressed, the trigger post triggers the control board to operate.

[0007] The button bracket is made of plastic and can be injection molded from PC or other transparent materials.

[0008] The objective of this utility model can also be optimized by the following technical measures.

[0009] Preferably, the bottom of the keycap is provided with a lip, and when the keycap is installed into the container cavity, the lip fits tightly against the retaining edge.

[0010] The keycaps are made of silicone, which provides elasticity when the keys are pressed down.

[0011] Preferably, the button bracket has a through hole corresponding to the keycap position, and the trigger post is cantilevered and installed in the through hole.

[0012] The button support structure has a central opening, making it a cantilever button to provide flexibility to the button support.

[0013] By adopting the above technical solution, this utility model separates the keycaps from the key bracket and uses a control board to press the keys and keycaps together, making the waterproof effect of the key structure more effective. Separating the keycaps from the key bracket allows for mass production of these two components, significantly reducing costs. Attached Figure Description

[0014] Figure 1 This is an exploded view of the present invention.

[0015] Figure 2 This is a cross-sectional view of the present invention.

[0016] Figure 3 for Figure 2 Enlarged view of part A. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Combination Figure 1 A waterproof button structure for a juicer includes a base 4, a button cap 1, a button bracket 2, and a control board 3. The base 4 has a receiving cavity 41 with a button opening 43 and a lower opening. A retaining edge 42 is provided at the button opening 43. The button cap 1, the button bracket 2, and the control board 3 are sequentially installed into the receiving cavity 41 from the lower opening. The button cap 1 extends outward from the button opening 43. When the control board 3 is fastened in the receiving cavity 41, the control board 3 presses upward against the button bracket 2, so that the retaining edge 42 and the button cap 1 fit tightly together.

[0019] The button bracket 2 is provided with a trigger post 21. The two ends of the trigger post 21 abut against the keycap 1 and the control board 3 respectively. When the keycap 1 is pressed, the trigger post 21 triggers the control board 3 to operate.

[0020] The keycap 1 has a lip 11 around its bottom. When the keycap 1 is installed into the cavity 41, the lip 11 fits tightly with the edge 42. The keycap 1 is made of silicone and has thin sides, which provides elasticity for the key to be pressed down. The bottom lip 11 is even thinner, which allows for better compression and waterproofing of the key bracket 2 under the screws on the control board 3. The top center is thickened and flattened to allow the key bracket 2 to withstand pressure better and improve the feel when the fingers press.

[0021] Combination Figure 2 and Figure 3 The button bracket 2 has a through hole 22 corresponding to the keycap 1, and the trigger post 21 is cantilevered and installed in the through hole 22. The button bracket 2 is structurally open in the middle, making it a cantilever button. To provide elasticity to the button bracket 2, the end of the trigger post 21 is cylindrical, with the upper end fitting into the keycap 1 for easy assembly and positioning, and the lower end directly contacting the button on the control board 3.
