Description

Technical Field

[0001] This utility model relates to the technical field of drainers, and in particular to a push-button drainer structure. Background Technology

[0002] In daily life, we often buy ceramic or glass basins to place on washbasins. These basins have drains at the bottom to flush wastewater into the pipes. However, push-button drains are becoming increasingly common. To facilitate cleaning, most push-button drains are simply inserted directly into the drain hole for easy removal. This method of direct insertion into the sealing hole and connection via a gasket can easily lead to loosening due to accidental contact.

[0003] Chinese Patent Publication No. CN214497724U, published on October 26, 2021, discloses a drainer for easy and quick cleaning. The drainer includes a main body, with a water plug assembly at one end and a tailpipe body at the other end. Both the water plug assembly and the tailpipe body are detachably connected to the main body. The main body is tubular in shape, and a protrusion is provided on its inner sidewall. One end of the water plug assembly is located outside the main body, while the other end is confined within the main body by the protrusion. A drawback of this invention is that the pressing core is placed directly inside the main body, making it prone to loosening due to accidental activation. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of existing technologies where pressing devices are prone to loosening due to accidental contact, and provides a pressing-type drain structure in which the pressing component is detachably connected to the main body via a plug-in tube.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A push-button drain structure includes an installation tube, a plug-in tube, a push-button assembly, and a sealing assembly. The plug-in tube is placed inside the installation tube and is detachably connected to the installation tube. The plug-in tube is in contact with the inner wall of the installation tube. The push-button assembly is installed inside the plug-in tube. The sealing assembly is installed at the upper end of the push-button assembly and is in contact with the plug-in tube.

[0007] An integrated device is installed inside an installation tube, which is then connected and fixed to the sink. A plug-in tube is installed inside the installation tube, detachably connected to the inner wall of the installation tube. A pressing component is then installed inside the plug-in tube, allowing the plug-in tube to be opened and closed. A sealing component is installed at the upper end of the pressing component, fitting snugly against the upper end of the plug-in tube to improve sealing performance. When cleaning, the plug-in tube needs to be removed. This fixed connection between the pressing component and the plug-in tube enhances the stability of the pressing component, preventing accidental loosening and ensuring a better seal. This achieves the goal of detachably connecting the pressing component to the main body via the plug-in tube.

[0008] Preferably, the plug-in tube has locking posts on both sides, and the inner wall of the mounting tube has a locking groove that matches the locking posts. The locking groove has an L-shaped cross-section. One end of the locking post is connected to the plug-in tube, and the other end is placed in the locking groove. The upper end of the locking groove opens at the upper end of the mounting tube. The locking posts installed on both sides of the plug-in tube enter the mounting tube along the opening end of the locking groove. Then, the locking posts move to the bottom end of the locking groove and are rotated. By rotating, the locking posts are screwed into the other side of the locking groove, thus completing the connection between the plug-in tube and the mounting tube. This design allows for quick installation of the plug-in tube.

[0009] Preferably, the pressing assembly includes a pressing rod and a connecting tube. The bottom surface of the insertion tube is provided with a mounting plate, and the mounting plate is provided with a plurality of circumferentially distributed support rods. One end of each support rod is connected to the mounting plate, and the other end of each support rod is connected to the inner wall of the insertion tube. A screwing tube is installed on the mounting plate, and the lower end of the connecting tube is threadedly connected to the screwing tube. The lower end of the pressing rod is placed inside the connecting tube, and a pressing plate is installed on the other end of the pressing rod. The connecting tube is provided with a lifting groove, and a screw is provided on the connecting tube. One end of the screw passes through the lifting groove and is connected to the pressing rod. The bottom surface of the insert tube is equipped with a mounting plate, which is connected to the inner wall of the insert tube via a support rod. Water can be leaked through the insert tube. The screw tube installed on the mounting plate is threadedly connected to the connecting tube of the pressing assembly. Then, the lower end of the pressing rod is placed inside the connecting tube, and the upper end of the pressing rod is equipped with a pressing plate for pressing. The pressing rod is connected to the connecting rod by a screw. The screw passes through the lifting groove and connects to the pressing rod. Under the constraint of the screw, the movement stroke of the pressing rod is consistent with the length of the lifting groove. When the pressing rod descends, it can close the upper end of the insert tube. When the pressing rod rises, it can open the insert tube for water leakage. This design can open and close the tube.

[0010] Preferably, a guide block is installed at the lower end of the pressing rod, and a guide groove is provided on the guide block. The guide groove is V-shaped and the opening faces downward. The length of one side of the guide groove is less than the length of the other side. A connecting rod is installed at the lower end of the connecting tube, and a pull rod is provided on the connecting rod. One end of the pull rod is rotatably connected to the connecting rod, and the other end of the pull rod is placed in the guide groove. A spring is provided in the insertion tube. One end of the spring contacts the connecting rod, and the other end of the spring is connected to the lower end of the pressing rod. To achieve the rebound effect during the pressing process, a guide block is installed at the lower end of the pressing rod. The guide block has a downward-opening guide groove. One end of the V-shaped guide groove is shorter. A connecting tube is installed at the lower end of the insertion tube. Then, one end of the pull rod is connected to the connecting rod, and the other end of the pull rod is placed in the guide groove. A spring installed in the insertion tube applies an upward elastic force to the pressing rod. To close the insertion tube, the pressing rod descends, and one end of the pull rod enters the shorter end of the guide groove, thus closing the insertion tube. To open the upper end of the insertion tube, simply press the pressing rod and move the pull rod to the longer end of the guide groove. This design achieves the rebound effect of the pressing rod.

[0011] Preferably, a filter frame is installed at the lower end of the plug-in tube, and the filter frame is detachably connected to the plug-in tube. To prevent debris from clogging the inside of the drain, a filter frame is installed at the bottom of the plug-in tube. When water leaks from the plug-in tube, it passes through the filter frame and is filtered. Debris can be quickly cleaned by removing the filter frame. This design effectively filters debris.

[0012] Preferably, the sealing assembly includes a bonding plate mounted on the lower end face of the pressing plate. A sealing block is mounted on the bonding plate, and the sealing block matches the inner wall of the insertion tube. A sealing gasket is mounted on the upper end of the mounting tube, and a fastening nut is provided on the mounting tube. The fastening nut is threaded to the outer side of the mounting tube, and a second sealing gasket is provided on the upper end of the fastening nut. The bonding plate of the sealing assembly is mounted on the bottom surface of the pressing plate. When the pressing plate closes the insertion tube, the bonding plate is in contact with the top surface of the mounting tube, thereby improving the sealing effect. Furthermore, the sealing block mounted on the bonding plate, in the closed state, is in contact with the inner wall of the insertion tube, further improving the sealing effect. Both the bonding plate and the sealing block are made of elastic material. The connection between the mounting tube and the tabletop is achieved by fixing the mounting tube to the tabletop with a fastening nut, and then installing a second sealing gasket on the fastening nut. A first sealing gasket is also installed at the top of the mounting tube. When connected to the tabletop, these sealing gaskets seal the upper and lower ends of the mounting hole respectively. This design improves the sealing effect.

[0013] The beneficial effects of this utility model are: the pressing component is detachably connected to the main body through the plug-in tube, which allows for quick installation of the plug-in tube, opening and closing of the sealing tube, realizing the rebound of the pressing rod, filtering garbage, and improving the sealing effect.
