DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1

[0038] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the wash basin drainer structure provided in this embodiment which can be easily cleaned includes a wash basin body 1 and a drainer 2 .

[0039] On the bottom wall of the basin body 1, an upper drainage channel 11, a middle channel 13 and a lower drainage channel 12 are sequentially provided from top to bottom. The upper drainage channel 11, the middle channel 13 and the lower drainage channel 12 are coaxially arranged, that is, the axis aa of the upper, middle and lower channels coincide. Among them, the inner diameter of the middle channel 13 is larger than the inner diameter of the upper drainage channel 11.

[0040] The water inlet 111 at the upper end of the upper drainage channel of the basin body 1 is a trumpet-shaped opening structure, and the upper end of the inner wall of the water inlet 111 can also adopt a rounded structure (such as Figure 4 As shown), it is beneficial to quickly drain the water or liquid in the basin body 1, and also convenient for sanitary cleaning of the water inlet 111 at the upper end of the upper drainage channel 11.

[0041] The drainer 2 includes: a drain seat 21, a bounce switch 22, a water stop pressure cover 23, a locking nut 24, a water stop ring 25, an upper sealing ring 26, a lower sealing ring 27 and a tail pipe 28, wherein the drain seat 21 is installed in the lower drainage channel 12 of the basin body 1, specifically, the flange 211 at the upper end of the drain seat 1 is located on the surface of the upper end of the lower drainage channel 12, and the upper end of the drain seat 21 and the upper end of the lower drainage channel 12 can be sealed and connected; the lower end of the drain seat 21 passes through the external pipe thread 212 below the lower drainage channel 12, and the external pipe thread 212 is connected to the locking nut 24, so that the drain seat 21 can be fixed in the lower drainage channel 12 of the basin body 1. An upper sealing ring 26 is arranged between the lower surface of the flange 211 at the upper end of the drain seat 21 and the upper end surface of the lower drain channel 12, which is conducive to better sealing connection between the upper end of the drain seat 21 and the upper end surface of the lower drain channel 12; a lower sealing ring 27 is arranged between the lower end surface of the lower drain channel 12 (i.e., the lower surface of the basin body 1) and the upper end of the locking nut 24, and the arrangement of the lower sealing ring 27 is conducive to better sealing connection between the drain seat 21 and the lower surface of the basin body 1. The lower end of the drain seat 21 passes through the internal pipe thread 213 below the lower drain channel 12 and is connected to the tail pipe 28.

[0042] like Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the pop-up switch 22 is installed in the drain seat 21, the lower end of the main body of the pop-up switch 22 is fixedly connected to the central bracket 213 in the drain seat 21, and the pop-up switch 22 passes through the driving rod 221 above the upper drain channel 11 and is fixedly connected to the lower end of the water stop pressure cap 23. A water stop ring 25 is arranged on the annular groove 231 of the water stop pressure cap 23, and the water stop ring 25 is made of elastic materials such as rubber or silicone. The water stop ring 25 includes an inner ring 25a and an outer ring 25b which are integrally formed, and the outer ring 25b extends radially outward from the outer surface of the inner ring 25a, and the thickness gradually decreases. The inner ring 25a of the water stop ring 25 is embedded in the annular groove 231 of the water stop pressure cover 23 to prevent the water stop ring 25 from falling off; the outer ring 25b of the water stop ring 25 can abut against the inner wall of the water inlet 111 of the upper drainage channel 11, and is used to seal the water stop pressure cover 23 and the water inlet 111 of the upper drainage channel 11. The thickness of the outer ring 25b of the water stop ring 25 is gradually thinned radially outward, so that the water stop pressure cover 23 saves effort when applying pressure downward.

[0043] In this embodiment, the inner diameter of the upper drainage channel 11 is larger than the inner diameter of the lower drainage channel 12. When the drainer 2 is installed, the drain seat 21 is inserted into the lower drainage channel 12 from the water inlet 111 at the upper end of the upper drainage channel 11 above the basin body 1, and the drain seat 21 is fixed in the lower drainage channel 12 through the locking nut 24 from the bottom of the lower drainage channel 12. It is convenient to assemble the drain seat 21 of the drainer 2 from the top of the basin body 1. The main body of the bounce switch 22 is fixed on the central bracket 213 in the drain seat 21, and the driving rod 221 of the bounce switch 22 passes through the upper drainage channel 11 and is fixedly connected to the lower end of the water stop pressure cover 23. The water stop ring 25 is arranged on the water stop pressure cover 23.

[0044] When in use, press the water-stop pressure cover 23 once, the water-stop pressure cover 23 and the water-stop ring 25 pop up, and the water or liquid in the basin body 1 can be quickly discharged downward from the water inlet 111 at the upper end of the upper drainage channel 11. Since the water or liquid is not blocked at the water inlet 111 of the upper drainage channel 11 of the basin body 1, it is beneficial to the hygienic cleaning of the water inlet 111 at the upper end of the upper drainage channel. Therefore, it is not easy for stains to accumulate and bacteria to breed at the water inlet 111 at the bottom of the basin body 1.

[0045] like Figure 1 , Figure 3 and Figure 4As shown, the basin drain structure further includes: an overflow channel 14, which is used to connect the overflow port 15 on the side wall of the basin body 1 with the overflow hole on the side wall of the middle channel 13; the overflow channel 14 includes: a side wall channel 141 extending along the side wall of the basin body 1, and a bottom wall channel 142 extending along the bottom wall of the basin body 1. The overflow channel 14 is integrally formed with the upper drainage channel 11, the middle channel 13, and the lower drainage channel 12 of the basin body 1, which is conducive to reducing the installation cost of the drain.

[0046] To sum up, the basin drain structure of the present embodiment adopts three channels with different aperture sizes set on the basin, including an upper drainage channel 11, a middle channel 13 and a lower drainage channel 12 which are coaxial from top to bottom. Different from the drain in the prior art which is installed at the drain outlet of the bottom wall of the basin, the present application installs the drain seat of the drain in the lower drainage channel, avoiding the problem of a gap between the drain seat of the drain and the edge of the water inlet at the upper end of the upper drainage channel on the bottom wall of the basin body, which makes cleaning inconvenient due to the gap.

[0047] Embodiment 2

[0048] See also Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.14 The easy-to-clean basin drain structure provided in this embodiment is different from that in the first embodiment in that the inner diameter of the upper drainage channel 11 is smaller than the inner diameter of the lower drainage channel 12, so that the drain seat 21 of the drain 2 can be installed from the bottom of the basin body 1. When installing the drainer 2, the flange 211 at the upper end of the drain seat 21 is inserted into the upper end surface of the lower drainage channel 12 below the basin body 1. A clamping seat 29 is provided between the lower end surface of the flange 211 of the drain seat 21 and the upper end surface of the lower drainage channel 12. The clamping seat 29 has a clamping ring, and the long side dimension of the clamping ring is larger than the inner diameter dimension of the lower drainage channel 12. Therefore, the upper end of the drain seat 21 is fixedly connected to the upper end surface of the lower drainage channel 12 through the clamping seat 29. The external pipe thread 212 at the lower end of the drain seat 21 is located below the lower drainage channel 12. The drain seat 21 can be fixed in the lower drainage channel 12 of the basin body 1 by connecting the external pipe thread 212 of the drain seat 21 with the locking nut 24.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
