Description
Technical Field
[0001] The utility model relates to a drain, in particular to a drain with an anti-loosening structure. Background Art
[0002] The drain is a drainage device installed in the drain hole below the wash basin. The drain can be opened and closed by the flip cover in the upper end port of the drain. When the drain is installed in the drain hole of the wash basin, the limit part of the upper end of the drain is stuck on the lower inner wall of the basin, and a limit nut that fits the lower outer wall of the basin is screwed on the outside of the drain to fix the drain. The lower end of the drain that passes downward to the outside of the drain hole is used to connect to the drainage pipe to facilitate the discharge of water into the sewer.
[0003] The traditional drain only has the function of drainage. In the actual use of the drain, there is basically no need to accumulate water in the wash basin. Most of the time, the water flow from the faucet is used for flushing. Therefore, in order to facilitate drainage, the drain cover is often in the open state. When the user completes the flushing with the water flow from the faucet, the water will be directly discharged into the drainage pipe through the drain and finally into the sewer. This situation will cause the wash basin and the sewer to be in a through-state for a long time, which can easily cause the odor in the sewer to rise into the wash basin through the drain, and finally cause the indoor air to be contaminated. Pollution. In order to avoid this situation, an anti-odor structure will be set inside the drain. The anti-odor structure can automatically open the lower end of the drain when the drain is draining, and automatically close the lower end of the drain when the drain is not draining. The anti-odor structure is generally directly screwed into the drain through a base through a threaded connection. When the drain is draining, the water flow will continuously impact the anti-odor structure, which can easily cause the anti-odor structure to loosen, and ultimately affect the anti-odor effect. In severe cases, the anti-odor structure may even fall off into the drainage pipe connected to the lower end of the drain, causing the drainage pipe to be blocked. Summary of the Invention

[0024] Glue is applied between the inner wall of the axial screw hole 607 and the outer wall of the axial screw 609 , and between the inner wall of the radial screw hole 611 and the outer wall of the radial screw 612 .
[0025] The method of using the utility model is as follows:
[0026] When the drain needs to be drained, the flap 3 can be pressed first to rotate it. When the angle of the flap 3 is changed, the upper end port of the shell 1 is no longer blocked and sealed by the flap 3. When the water flow from the faucet falls to the wash basin, the water flow will enter the shell 1 through the upper end port of the shell 1 under the action of gravity. At this time, the support seat 601 presses the water-passing plate 501 on the limiting step 101 through the guide column to fix the position of the water-passing plate 501. The water flow can only flow downward through the upper drainage hole 507 on the water-passing plate 501. When the upper surface of the deodorizing plate 503 blocks and seals the lower end opening of the upper drainage hole 507, the downward water flow will push the deodorizing plate 503 downward through the upper surface of the deodorizing plate 503. At this time, the deodorizing plate 503 will move steadily downward along the trajectory of the guide column 502, and there is a sliding gap 504 between the outer wall of the deodorizing plate 503 and the lower inner wall of the shell 1. The existence of the sliding gap 504 can effectively reduce the deodorizing plate 5 03 resistance when moving downward. When the odor-proof plate 503 moves downward, the spring 506 is compressed and generates elastic force. At the same time, the lower surface of the water-passing plate 501 no longer blocks and seals the upper end opening of the lower drainage hole 508. The water flow in the upper drainage hole 507 can flow into the lower drainage hole 508 and the sliding gap 504 through the gap between the lower surface of the water-passing plate 501 and the upper surface of the odor-proof plate 503. Then the water flows through the lower drainage hole 508 and the sliding gap 504 into the lower space of the shell 1, and then is discharged to the outside of the shell 1 through the water outlet hole 602, and flows into the drainage pipe connected to the lower end of the shell 1, and finally flows into the sewer to realize the discharge of water. When the water discharge is completed, the odor-proof plate 503 will move upward and reset under the elastic force of the spring 506. At this time, the lower end opening of the upper drainage hole 507 and the upper end opening of the lower drainage hole 508 are blocked and sealed again, and the odor rising from the sewer is trapped in the lower space of the shell 1.
[0027] It can be seen that the deodorizing structure is firmly restricted in the lower space of the drain casing 1 by the support seat 601. Therefore, it is only necessary to ensure that the support seat 601 is not loose to avoid the deodorizing structure from loosening. The fixing portion 604 at the lower end of the support seat 601 is fixed to the lower end of the casing 1 by a number of evenly distributed axial screws 609. This fixing method is not only convenient for the disassembly and assembly of the support seat 601, but also can effectively ensure the stability of the support seat 601 when it is arranged at the lower end port of the casing 1. When the water flows into the drainage pipe through the water outlet 602, the water flow will also continuously impact the upper surface of the support seat 601 downward, and the upper surface of the head of the axial screw 609 is in contact with the lower surface of the support seat 601. Therefore, the axial screw 609 will also be subjected to the downward pressure of the water flow. At this time, the axial screw 609 is easily affected by the impact of the water flow, causing itself to loosen downward along the internal thread trajectory of the axial screw hole 607. If the support seat moves downward, the entire deodorizing structure will loosen downward. However, the presence of the support plate 606 can effectively limit the downward movement of the axial screw 609, thereby effectively preventing the support seat 601 from loosening downward. When the radial screw 612 is perpendicular to the axial screw 609, the radial screw 612 can only be loosened in the radial direction. When the radial screw 612 is loosened radially, the height of the positioning plate 605 will not change. The upper surface of the support plate 606 is always tightly pressed against the lower surface of the head of the axial screw 609, thereby ensuring the stability of the support seat 601 when it is fixed to the lower end of the shell 1 by the axial screw 609 to the greatest extent.
[0028] In summary, the utility model can effectively prevent the odor of the sewer from rising through the upper end port of the shell 1 through the anti-odor structure, thereby achieving an anti-odor effect, and the anti-loosening structure can effectively ensure the stability of the anti-odor structure, effectively preventing the anti-odor structure from loosening under the continuous impact of water flow, and further preventing the anti-odor structure from falling off into the drainage pipe connected to the lower end of the shell 1, causing blockage of the drainage pipe.
[0029] At least two radial through-holes 610 are provided on the upper part of the positioning plate 605 opposite to the positioning part 102; the outer wall of the positioning part 102 is provided with a plurality of radial screw holes 611 which are in communication with the radial through-holes 610, and a radial screw 612 passes through the radial through-holes 610 and is screwed into the radial screw holes 611. The upper part of the positioning plate 605 is located between the outer wall of the positioning part 102 and the head of the radial screw 612, and the radial screw 612 is perpendicular to the axial screw 609. The above design can effectively ensure that the upper part of the positioning plate 605 is fixed by at least two radial screws 612, thereby further ensuring the stability of the positioning plate 605.
[0030] The support plate 606 is covered with a buffer sleeve 613 made of rubber. The upper outer wall of the buffer sleeve 613 fits the lower surface of the head of the axial screw 609. The buffer sleeve 613 can effectively buffer the pressure acting on the axial screw 609 through its own elasticity, further improving the anti-loosening effect.
[0031] The diameter of the water outlet hole 602 decreases gradually from top to bottom. This structural design facilitates the downwardly discharged water flow to quickly converge into the water outlet hole 602, effectively improving the drainage efficiency of the water outlet hole 602.
[0032] Glue is coated between the inner wall of the axial screw hole 607 and the outer wall of the axial screw 609, and between the inner wall of the radial screw hole 611 and the outer wall of the radial screw 612. The presence of glue can further ensure the stability of the axial screw 609 when it is screwed into the axial screw hole 607 and the radial screw 612 when it is screwed into the radial screw hole 611, thereby further improving the anti-loosening effect of the anti-loosening structure.
