Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of keyboard, concretely is mechanical keyboard with multiple waterproof rubber rings. BACKGROUND

[0002] Mechanical keyboard is a widely used input device, and it is favored by many users because of its unique mechanical structure. Compared with traditional membrane keyboard, mechanical keyboard not only provides more crisp key feedback, but also has longer service life and higher precision. Each key has an independent mechanical switch below, when the user presses the key, the switch will respond quickly, producing obvious touch and sound, which makes mechanical keyboard perform well in games, programming and typing scenarios. However, due to the design of mechanical keyboard, there is a gap between the key and the keyboard, which makes water penetrate into the internal part of the keyboard through the gap when liquid is accidentally spilled, causing the circuit board to short circuit or damage, seriously affecting the use function and life of the keyboard.

[0003] The patent with publication number CN217061851U discloses a waterproof mechanical keyboard, which comprises a panel and keycaps. A plurality of keycaps are arranged on the top of the panel. A plurality of through holes are arranged in the panel near the bottom of the keycaps. A plurality of water baffle plates are arranged on both sides of the panel near the keycaps. A plurality of rubber pads are arranged on the top of the water baffle plates. A plurality of flow guide grooves are arranged between the water baffle plates on the panel. A plurality of moisture-proof plates are arranged at the bottom of the panel. The utility model has the advantages that the water baffle plates are arranged on both sides of the panel near the keycaps, which can effectively block the liquid and prevent the liquid from flowing into the through holes and damaging the circuit board. The flow guide grooves arranged between the keycaps can prevent the liquid from accumulating on the surface of the keycaps, preventing the user from being affected during normal use. At the same time, the liquid can be collected in the flow guide grooves and automatically discharged outward, thereby effectively improving the waterproof performance of the device.

[0004] The above-mentioned prior art arranges water baffle plates on both sides of the panel near the keycaps, which can block the liquid, and uses rubber pads to further play a waterproof role. However, in order for the key to be pressed down smoothly, the height of the water baffle plate must be set very low, which results in a small water blocking effect of the water baffle plate. Even though the rubber pad can prevent water from directly entering the gap of the key, it is difficult to remove the water on the surface of the rubber pad. When the key is pressed down, the deformation of the rubber pad may cause the water attached to its surface to still enter the interior. In addition, the rubber pad will produce friction resistance to the key during use, affecting the user's hand feeling. Furthermore, the rubber pad will gradually wear out during the use of the key, further weakening its waterproof effect. In view of this, we propose a mechanical keyboard with multiple waterproof rubber rings. SUMMARY
