[0039] Embodiment one

[0040] Please refer toFigure 1 and Figure 2 As shown in the figure, the new basin structure 1 of the present embodiment comprises a basin body 10 and a drain seat 20. The basin body 10 has a water tank 11 and a table top 14. A drain hole 111 is formed in the bottom wall of the water tank 11. The lower water outlet 113 of the upper end of the drain hole 111 is in a horn structure, which is beneficial to the rapid discharge of water or liquid in the water tank 11 through the drain hole 111. The drain seat 12 is arranged below the drain hole 111 of the water tank 11 of the basin body 1. The drain seat 12 is provided with an upper passage 121 and a lower passage 122 which are connected in series along the central axis a-a. The upper passage 121 is used for the communication between the lower end of the drain hole 111 and the upper end of the lower passage 122 of the drain seat 20. The lower passage 122 is used for installing a drain. The inner diameter of the upper passage 121 is larger than that of the lower passage 122. An annular step 124 is formed at the connection of the upper passage 121 and the lower passage 122, which is used for installing the flange of the drain.

[0041] As shown in the figure, Figure 1 and Figure 3 and Figure 4 As shown in the figure, the outer surface of the water tank 11 of the basin body 10 is provided with an overflow pipe 13. One end of the overflow pipe 13 is connected with the overflow port 112 on the side wall of the water tank 11, and the other end is connected with the through hole 123 on the side wall of the upper passage 121 of the drain seat 12.

The basin body 10, the drain seat 12 and the overflow pipe 13 are integrally formed. The new basin structure is preferably made of ceramic material. The integrally formed structure is simple in design and eliminates the need for additional installation of an overflow pipe, thereby reducing the production cost of the basin.

[0042] Embodiment two

[0043] As shown in the figure, Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The present embodiment proposes a basin which comprises a drain 2 installed in the new basin structure 1. When the drain 2 is closed, the water tank 11 of the basin structure 1 can store water. When the drain 2 is opened, the water tank 11 of the basin structure 1 can discharge water. Therefore, by closing or opening the drain 2, the water tank 11 of the basin structure 1 can be switched between water storage and water discharge.

[0044] The drain device 2 comprises a pipe base 21, a bounce switch 22, a water stop cover 23, a locking nut 24, a water stop sealing ring 25, an upper sealing ring 26, a lower sealing ring 27 and a tail pipe 28. The flange plate 211 at the upper end of the pipe base 21 is located on the annular step 124 of the upper passage 121 and the lower passage 122 of the drain seat 12 of the new type basin structure 1, the lower end of the pipe base 21 penetrates the pipe outer thread 212 below the lower passage 122 of the drain seat 12, is threadedly connected with the locking nut 24, and is fixed in the lower passage 122 of the drain seat 12. The outer thread 222 at the lower end of the bounce switch 22 is threadedly connected with the pipe inner support 213 of the pipe base 21, the transmission rod 221 at the upper end of the bounce switch 22 penetrates above the drain hole 111 of the water tank 11 of the new type basin structure 1, and is connected with the lower end of the water stop cover 23. The structure of the bounce switch 22 in the embodiment can adopt the prior art, and thus will not be described in detail.

[0045] The upper sealing ring 26 is arranged between the lower surface of the flange plate 211 of the pipe base 21 and the annular step 124 of the drain seat 12, and seals and connects the upper end of the pipe base 21 with the upper end surface of the lower passage 122 of the drain seat 12. The lower sealing ring 27 is arranged between the lower end surface of the lower passage 122 of the drain seat 12 and the upper end of the locking nut 24. The lower sealing ring 27 is arranged to seal and connect the pipe base 21 with the lower end of the drain seat 12. The pipe inner thread at the lower end of the pipe base 21 is connected with the tail pipe 28. The tail pipe 28 is used to connect the drain pipe, so that the water tank 11 of the basin structure 1 can store water, and the water in the water tank 11 can be drained to the drain pipe through the drain device 2.

[0046] The water stop sealing ring 25 is installed on the water stop cover 23, and is used to seal between the water stop cover 23 and the water outlet 113 of the drain hole 111 of the water tank 11 of the basin structure 1, so that the water or liquid in the water tank 11 is not drained. The water stop sealing ring 25 is made of rubber or silica gel material, and comprises an inner ring 25a and an outer ring 25b which is integrally formed. The outer ring 25b extends radially and outwardly from the outer surface of the inner ring 25a, and gradually thins. The inner ring 25a of the water stop sealing ring 25 is embedded in the annular groove 231 of the water stop cover 23, so as to prevent the water stop sealing ring 25 from falling off the water stop cover 23. The outer ring 25b of the water stop sealing ring 25 can abut against the inner wall of the water outlet 113 of the drain hole 111, so as to seal and connect the water stop cover 23 with the water outlet 113 of the drain hole 111 of the water tank 11. The thickness of the outer ring 25b of the water stop sealing ring 25 gradually thins radially and outwardly.

[0047] In this embodiment, the inner diameter of the drain hole 111 in the bottom wall of the water tank 11 of the new type of basin structure 1 is larger than the inner diameter of the lower passage 122 of the drain seat 12. When installing the drain device 2, the pipe seat 21 is inserted into the lower passage 122 of the drain seat 12 from the lower water outlet 113 at the upper end of the drain hole 111 in the bottom wall of the water tank 11 from above the basin body 10. The pipe seat 21 of the drain device 2 is fixed in the lower passage 122 of the drain seat 12 by the threaded connection of the locking nut 24 and the pipe outer thread 212 of the pipe seat 21 below the lower passage 122 of the drain seat 12. Therefore, it is more convenient to assemble the pipe seat 21 of the drain device 2 from above the basin body 10. The main body of the bounce switch 22 is fixed in the pipe inner support 213 in the pipe seat 21. The transmission rod 221 of the bounce switch 22 protrudes above the drain hole 111 in the bottom wall of the water tank 11 and is fixedly connected with the lower end of the water stop gland 23. The water stop sealing ring 25 is arranged on the water stop gland 23.

[0048] The lower water outlet 111 at the upper end of the drain hole 111 in the bottom wall of the water tank 11 is a horn-shaped opening structure, which is beneficial to the rapid discharge of water or liquid in the water tank 11. When the water stop gland 23 of the drain device 2 is opened (i.e., the water stop gland 23 is in the rising state), the water stop gland 23 and the water stop sealing ring 25 of the drain device 2 are upwardly bounced by the bounce switch 22. The water stop gland 23 and the water stop sealing ring 25 are not in contact with the lower water outlet 111 at the upper end of the drain hole 111 in the bottom wall of the water tank 11. Therefore, it is beneficial to the sanitary cleaning of the lower water outlet 111 at the upper end of the drain hole 111 in the bottom wall of the water tank 11.

[0049] The technical effect of this embodiment is that the pipe seat 21 of the drain device 2 is installed in the lower passage 122 of the drain seat 12 of the basin structure 1, which avoids the gap between the pipe seat 21 of the drain device 2 and the lower water outlet 113 at the upper end of the drain hole 111 in the bottom wall of the water tank 11. The stain is difficult to clean in the gap.
