DRAINER WITH QUICK DRAINAGE AND IMPROVED STRUCTURE
A drainer with quick drainage and improved structure has a drain body and a draining unit disposed in the drain body for stopping and draining water; the draining unit includes a base, a movable element, a rotatable element, a spring for ejection, an engaging ring element, an upper cover, and a rubber piece. The base has an inner tube in the middle, a periphery ring body, and a plurality of connecting ribs. The inner tube has a top end being higher than a top of the periphery ring body and an engaging space formed on the inner periphery thereof for the base to be disposed inside the drain body. The spring for ejection, the rotatable element, and the movable element are sequentially disposed in the inner tube and then the engaging ring element is mounted on the top end of the inner tube to form a movable unit for pressing with the upper cover mounted on the movable element and the rubber piece mounted on the periphery of the upper cover.
1. Field of the Invention
The present invention relates to a drainer with quick drainage and improved structure, particularly to one that has a one-piece structure to withstand the strong compression impact when switching between a water draining status and a water stopping status.
2. Description of the Related Art
When the conventional bouncing rod type water draining device switches from a water draining status to a water draining status, the upper cover 46 would compresses the spring 44 for ejection and the engaging element 45 has to withstand the rapidly increasing impact force from the spring 44. When applied to basins, the impact is less and bearable, but when applied to bathtubs, the impact made by footsteps may be too strong for the structure due to its assembled engagement design.
Besides, the stretching height h1 of the upper cover 46 is limited in such design; in other words, the time spent for water drainage is relatively long. Also, such design does not has a distance long enough therein for the bouncing operation to be completely performed, leaving a problem of unsmooth switching between the water draining status and water stopping status.
SUMMARY OF THE INVENTIONA primary object of the present invention is to provide a drainer with an improved structure to overcome the problem with a weak structure in the prior art.
Another object of the present invention is to provide a drainer that is able to perform quick drainage and to switch between draining and stopping status.
Yet another object of the present invention is to provide a drainer that is able to perform smooth drainage.
To achieve the object mentioned above, the present invention comprises a drain body and a draining unit disposed in the drain body for stopping and draining water; the draining unit including a base, a movable element, a rotatable element, a spring for ejection, an engaging ring element, an upper cover, and a rubber piece; wherein the base has an inner tube in the middle, a periphery ring body, and a plurality of connecting ribs; the inner tube having a top end being higher than a top of the periphery ring body and having an engaging space formed on the inner periphery thereof for the base being disposed inside the drain body; the spring for ejection, the rotatable element, and the movable element being sequentially disposed in the inner tube; then the engaging ring element being mounted on the top end of the inner tube, forming a movable unit for pressing with the upper cover mounted on the movable element and the rubber piece mounted on the periphery of the upper cover.
Preferably, the connecting ribs are spirally arranged, and each of which further has a guiding concave arranged thereon; the drain body has inner screw threads arranged therein and the periphery ring body has outer screw threads arranged on the periphery thereof for engaging the base and the drain body, therefore disposing the base inside the drain body. In addition, the movable element has a protrusion end on the top thereof that has a threaded periphery for engaging inside screw threads arranged at the bottom periphery of the upper cover, therefore fixedly mounting the upper cover on the movable element. And, the rubber piece has a flange formed around the periphery thereof.
As structures disclosed above, the present invention has the bottom of the inner tube formed in one-piece to provide a strong structure for the application in bathtubs. Also, the upper cover is designed to stretch higher and the connecting ribs have guiding concaves arranged thereon, ensuring a quick drainage and a smooth operation in switching between draining and stopping status.
Referring to
The base 21 has an inner tube 211 in the middle, a periphery ring body 212, and a plurality of connecting ribs 213. The inner tube 211 has a top end arranged higher than a top of the periphery ring body 212. The connecting ribs 213 are spirally arranged and each of which further has a guiding concave arranged thereon. The inner tube 211 further has an engaging space 214 formed on the inner periphery thereof. The drain body 10 has inner screw threads 101 arranged therein and the periphery ring body 212 has outer screw threads 215 arranged on the periphery thereof for engaging the base 21 and the drain body 10, therefore disposing the base 21 inside the drain body 10. Then the spring 24 for ejection, the rotatable element 23, and the movable element 22 are sequentially disposed in the inner tube 211 and the engaging ring element 25 is mounted on the top end of the inner tube 211, forming a movable unit for pressing 20a. The movable element 22 has a protrusion end 221 on the top thereof that has a threaded periphery 222. At the bottom periphery of the upper cover 26 a hole 261 is arranged thereon, and the hole 261 has screw threads 262 arranged therein for engaging the threaded periphery 222, therefore fixedly mounting the upper cover 26 on the movable element 22. The rubber piece 27 is mounted on the periphery of the upper cover 26 and further has a flange 271 formed around the periphery thereof.
With structures disclosed above, when the present invention switches a water draining status as shown in
Moreover, the inner tube 211 has the top end thereof arranged higher than the top of the periphery ring body 212, resulting in the upper cover 26 in water draining status being ejected higher as the movable element 22 reaching a higher point, lengthening the height h2 of the upper cover 26 and increasing the speed of water drainage. Also, the inner tube 211 has a longer distance therein for the movable unit for pressing 20a to have longer distance for operation. Consequently, the present invention has a feature of smooth switching between a water draining status and a water stopping status. On the other hand, the connecting ribs 213 are spirally arranged and have guiding concaves thereon, which is able to assist in water drainage during the operation, making it another feature of the present invention.
Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
