[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0020] like Figures 1 to 3 As shown, an embodiment of the present application provides a height-adjustable double-sealed floor drain, comprising a sleeve 10, an adjusting liner 20, a water cup cover 30 and a sealing bucket 40, the inner wall of the sleeve 10 being provided with an internal thread, the adjusting liner 20 being provided with an external thread, the adjusting liner 20 being sleeved in the top of the sleeve 10 and being threadedly connected to the sleeve 10, an inner tube 21 extending upward from the bottom of the adjusting liner 20, the water cup cover 30 being covered inside the adjusting liner 20 and sleeved outside the inner tube 21, the sealing bucket 40 being rotatably disposed in the sleeve 10 and being located below the inner tube 21, a counterweight block 41 being provided at one end of the sealing bucket 40, and the other end being used to open or close the outlet of the inner tube 21.
[0021] like Figures 1 to 3 As shown, the casing 10 is pre-buried in the water discharge position, the bottom of the casing 10 is designed to be funnel-shaped, the bottom of the casing 10 is used to connect with the external drainage pipe, the upper inner wall of the casing 10 is provided with an internal thread, the adjustment liner 20 is provided with an external thread, the adjustment liner 20 is sleeved in the casing 10, and the height between the adjustment liner 20 and the casing 10 can be adjusted. During installation, the height of the adjustment liner 20 can be adjusted according to the actual ground size, so that the upper surface of the adjustment liner 20 is consistent with the ground height, and the counterweight block 41 itself Under the action of gravity, the other end of the sealing bucket 40 closes the outlet of the inner tube 21 upward, and the sealing bucket 40 forms a seal with the outlet of the inner tube 21. The water cup cover 30 is placed inside the regulating liner 20 and sleeved outside the inner tube 21 in the liner. A first flow channel 31 is formed between the water cup cover 30 and the outer wall of the regulating liner 20, and a second flow channel 22 is formed between the inner wall of the regulating liner 20 and the outer wall of the inner tube 21. When water passes through the first flow channel 31, the second flow channel 22 and the inner tube 21, a water seal is formed. At the same time, the water flows upward and downward, and then forms a siphon effect. The greater the water flow in the room, the greater the drainage capacity.
[0022] like Figures 1 to 3As shown, the water flow process is that the indoor drainage first passes through the first flow channel 31, the second flow channel 22 and the inner tube 21, and the sealing bucket 40 is opened by the action of the water flow, and flows out through the bottom of the sleeve 10; when the water in the inner tube 21 is drained, the sealing bucket 40 closes the outlet of the inner tube 21 upward again under the action of the gravity of the counterweight; at the same time, a certain height of water is stored in the first flow channel 31 and the second flow channel 22 to form a water seal, and at this time the floor drain is double-sealed.
[0023] like Figures 1 to 3 As shown, the height-adjustable double-sealed floor drain further comprises a grate 50, which covers the top of the adjustable liner 20. The grate 50 is installed at the top of the liner to filter some large particle stains.
[0024] like Figures 1 to 3 As shown, an extension tube 23 extends downward from the inner tube 21 , and the extension tube 23 extends into the sleeve 10 .
[0025] like Figures 1 to 3 As shown, a connecting pipe 11 is provided at the bottom of the sleeve 10 , and the connecting pipe 11 forms an angle with the sleeve 10 .
[0026] like Figures 1 to 3 As shown, the angle between the connecting pipe 11 and the sleeve 10 is 90 degrees. The connecting pipe 11 and the sleeve 10 are an integrated structure, and the connecting pipe 11 is designed to be in a nearly horizontal position for connecting to an external drainage pipe. The 90-degree connecting pipe 11 is equivalent to an elbow, which saves an elbow when installing the drainage pipe.
[0027] like Figures 1 to 3 As shown, a sealing ring is provided on the upper surface of the other end of the sealing bucket 40. The sealing ring plays a sealing role.
[0028] like Figures 1 to 3 As shown, the sealing bucket 40 is rotatably connected to the bottom of the adjusting liner 20 via a rotating shaft. The sealing bucket 40 moves upward or downward relative to the sleeve 10 along with the adjusting liner 20.
[0029] like Figures 1 to 3 As shown, the angle between the connecting pipe 11 and the sleeve 10 is 90 degrees, the connecting pipe 11 is close to the horizontal position, and the bottom of the sleeve 10 is a smooth funnel shape, which directly makes the floor drain have the function of an elbow, saving height space while ensuring drainage.
[0030] like Figures 1 to 3 As shown, the threads of the adjusting liner 20 and the sleeve 10 cooperate so that the upper surface of the adjusting liner 20 is flush with the ground. In this way, even if there is a slight error in the height dimension of the embedded sleeve 10, it can be adjusted to the appropriate position through the threads when the floor drain adjusting liner 20 is installed.
[0031] like Figures 1 to 3 As shown, the water cup cover 30 and the inner lining design form an ingenious large upper and lower annular channel and form a water seal, which forms a siphon principle while draining water. The more water outside, the faster the water is drained. This reduces the volume of the floor drain while ensuring sufficient drainage capacity.
[0032] The above is a specific implementation of the present utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications are also considered to be within the protection scope of the present utility model.
