1. Field of the Invention
The invention herein relates to a button device that has waterproof function, especially a button device that prevents the waterproof ring from coming off owing to the pressing on the button device.
2. Prior Art
Please refer to
Under normal circumstances, the waterproof ring 2131c is anchored in the ring-shaped groove 912 of the cover 91, so that the waterproof function is secured through the combined interference through the two when external moisture is blocked from entering through the installation hole. However, when a user presses the push button 10c inwardly, the force created by the user's pressing affects the waterproof ring 2231c owing to the fact that the sealing member 20c is of an integral solid structure. It causes the waterproof ring 2121a to break away from the ring-shaped groove 912 when a user repeatedly presses the button device 1c for a significant period of time (as shown with arrow F1 in
Therefore, there is a definitive need to invent a new button device to resolve the problems addressed above.
The main purpose of the present invention is to provide a button device with waterproof function.
The other main purpose of the present invention is to provide an electronic device with the button device stated above.
To achieve the purpose stated above, the button device with waterproof function in the present invention is disposed at the electronic device. The electronic device comprises a cover, which includes an installation hole and a ring-shaped groove. The button device with waterproof function comprises a push button and a sealing member, wherein the sealing member comprises a trigger, which comprises a inner ring and a outer ring, wherein the outer ring is placed around the inner ring, and a partitioned groove is formed between the inner ring and the outer ring; the outer ring comprises a waterproof ring, which is used to be anchored in the ring-shaped groove.
In order to achieve the other purpose stated above, the electronic device comprises a cover and the button device with waterproof function stated above, wherein the cover comprises an installation hole and a ring-shaped groove, and the button device stated above is disposed at the installation hole.
These and other objects and advantages of the present invention will become apparent from the following description of the accompanying drawings, which disclose several embodiments of the present invention. It is to be understood that the drawings are to be used for purposes of illustration only, and not as a definition of the invention.

As shown in
In one of the embodiments of the present invention, the button device 1 comprises a push button 10 and a sealing member 20, wherein the push button 10 comprises a convex axis 11, and the sealing member 20 comprises a trigger 21 and a fixed element 22.
As shown in
The outer ring 211 is in a hollow cylinder shape, and at one end of it, a concave hole 2113 is formed. The concave hole 2113 is used to hold and connect with the convex axis 11 so that the push button 10 is connected with the sealing member 20.
The outer ring 213 is disposed around the inner ring 211, and a partitioned groove 217 is formed between the inner ring 211 and the outer ring 213. In one of the embodiments of the present invention, the partitioned groove 217 is in an L shape while the sealing member 20 is displayed with its cross-section view, and its width is virtually between 0.1 and 0.2 mm. The outer ring 213 comprises a frontal part 213a and a rear part 213b, wherein a waterproof ring 2131 is disposed at the frontal part 213a. The waterproof ring 2131 is anchored in the ring-shaped groove 912 of the cover 91 to prevent moisture from seeping through the installation hole 911 with the intimate interference of the two. The girth of the rear part 213b is greater than that of the frontal part 213a, therefore the rear part that sticks out from the frontal part forms the retaining part 2132, which is anchored around the installation hole 911 to prevent the button device 1 from slipping into the installation hole 911.
In one of the embodiments of the present invention, the shape of the fixed element 22 is a hollow cylinder, and the fixed element 22 is disposed in the partitioned groove 217. The volume of the fixed element 22 is virtually equal to the capacity of the partitioned groove 217. The fixed element 22 is used to support the trigger 21 to strengthen the entirety of the structure of the sealing member 20. In the embodiments of the present invention, the fixed element 22 is incorporated with the trigger 21 through hot pressing, yet the present invention is not limited to it. If there is sufficient hardness in the trigger 21, it is doable to incorporate the trigger 21 and the fixed element 22 into one single unit. In the embodiments of the present invention, the fixed element 22 is a metal piece, yet the present invention is not limited to it.
The bottom 215 is connected with one bottom of the inner ring 211 and the outer ring 213.

It is worth noting that the embodiments stated above only exemplify better embodiments in the present invention. To avoid redundant statements, detailed record of all possible variations is not provided. Yet this is understandable to those with general knowledge in this field. The elements stated above are not all necessary. Also to implement the present invention, it is possible to include elements with further details. The elements can be omitted or altered according to needs. And it is not impossible for the existence of other elements between any two elements. For example, if the trigger 21 is made of rubber that has high hardness, the fixed element 22 can be left out.
It is noted that the above-mentioned embodiments are only for illustration. It is intended that the present invention cover modifications and variations of present invention provided they fall within the scope of the following claims and their equivalents. Therefore, it will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention.
