Abstract

The present disclosure relates to a toilet seat, comprising a seat lower cover and a seat upper cover. The seat lower cover comprises a lower cover baseplate, a lower cover outer periphery boss, and a lower cover inner periphery boss. The seat upper cover comprises an upper cover baseplate, an upper cover outer periphery flange, an upper cover inner periphery flange, an upper cover outer periphery boss, and an upper cover inner periphery boss. The upper cover inner periphery boss is welded with the lower cover inner periphery boss, the upper cover outer periphery boss is welded with the lower cover outer periphery boss, and the upper cover outer periphery flange and the upper cover inner periphery flange are contacted with the lower cover baseplate respectively. The toilet seat is convenient to be assembled and is stable in structure through welded connection, so that a product quality is improved.

Claims (81)

1. A toilet seat, comprising:

a seat lower cover comprising:

a lower cover baseplate including a lower cover through hole;

a lower cover outer periphery boss surrounding an inner side of an outside edge of the lower cover baseplate; and

a lower cover inner periphery boss surrounding an outer side of the lower cover through hole;

a seat upper cover mounted on the seat lower cover, the seat upper cover comprising:

an upper cover baseplate including an upper cover through hole;

an upper cover outer periphery flange extending downwardly from an outside edge of the upper cover baseplate;

an upper cover inner periphery flange extending downwardly from an edge of the upper cover through hole;

an upper cover outer periphery boss surrounding an inner side of the upper cover outer periphery flange; and

an upper cover inner periphery boss surrounding an outer side of the upper cover inner periphery flange,

wherein the upper cover inner periphery boss is configured to be connected to the lower cover inner periphery boss,

wherein the upper cover outer periphery boss is configured to be connected to the lower cover outer periphery boss, and

wherein the upper cover outer periphery flange and the upper cover inner periphery flange are configured to be contacted with the lower cover baseplate respectively,

wherein an inner periphery flashing groove is formed between the upper cover inner periphery boss and the upper cover inner periphery flange,

wherein the upper cover inner periphery boss extends below a top portion of the inner periphery flashing groove and the upper cover inner periphery flange extends below the top portion of the inner periphery flashing groove,

wherein the upper cover inner periphery boss is configured to be welded with the lower cover inner periphery boss, and

wherein the inner periphery flashing groove is configured to receive flash overflow produced when welding the upper cover inner periphery boss and the lower cover inner periphery boss.

2. The toilet seat according to claim 1 ,

wherein a plurality of outer periphery boss recesses are arranged on the upper cover outer periphery boss at intervals.

3. The toilet seat according to claim 2 ,

wherein a plurality of inner periphery boss recesses are arranged on the upper cover inner periphery boss at intervals.

4. The toilet seat according to claim 1 ,

wherein a plurality of first reinforcing ribs are connected between the upper cover outer periphery boss and the upper cover outer periphery flange.

5. The toilet seat according to claim 1 ,

wherein a plurality of second reinforcing ribs are connected between the upper cover inner periphery boss and the upper cover inner periphery flange.

6. The toilet seat according to claim 1 ,

wherein a width of the lower cover inner periphery boss is greater than a width of the upper cover inner periphery boss, and

wherein a width of the lower cover outer periphery boss is greater than a width of the upper cover outer periphery boss.

7. The toilet seat according to claim 1 ,

wherein the upper cover outer periphery flange, the upper cover inner periphery flange, the upper cover outer periphery boss, and the upper cover inner periphery boss are integrally formed with the upper cover baseplate respectively.

8. The toilet seat according to claim 1 ,

wherein the lower cover outer periphery boss and the lower cover inner periphery boss are integrally formed with the lower cover baseplate respectively.

9. A method for assembling a toilet seat comprising a seat lower cover and a seat upper cover, the method comprising:

connecting an upper cover outer periphery boss of the seat upper cover to a lower cover outer periphery boss of the seat lower cover,

wherein the lower cover outer periphery boss is disposed at an inner side of an outside edge of a lower cover baseplate of the seat lower cover, and wherein an annular outer periphery platform is formed between the lower cover outer periphery boss and the outside edge of the lower cover baseplate, and

connecting an upper cover inner periphery boss of the seat upper cover to a lower cover inner periphery boss of the seat lower cover,

wherein the lower cover inner periphery boss is disposed at an outer side of a lower cover through hole of the lower cover baseplate, and wherein an annular inner periphery platform is formed between the lower cover inner periphery boss and an outside edge of the lower cover baseplate,

wherein the upper cover inner periphery boss is connected to the lower cover inner periphery boss via welding, allowing flash overflow produced when welding the upper cover inner periphery boss and the lower cover inner periphery boss to flow into an inner periphery flashing groove formed between the upper cover inner periphery boss and the upper cover inner periphery flange,

10. The method according to claim 9 , further comprising:

disposing at least a portion of an upper cover outer periphery flange of the seat upper cover on the annular outer periphery platform; and

disposing at least a portion of an upper cover inner periphery flange of the seat upper cover on the annular inner periphery platform.

11. The method according to claim 10 ,

wherein the upper cover outer periphery boss is connected to the lower cover outer periphery boss via welding,

wherein the method further comprises:

allowing flash overflow produced when welding the upper cover outer periphery boss and the lower cover outer periphery boss to flow into an outer periphery flashing groove formed between the upper cover outer periphery boss and the upper cover outer periphery flange.

12. The method according to claim 11 ,

wherein a plurality of first reinforcing ribs is formed between the upper cover outer periphery boss and the upper cover outer periphery flange, and

wherein the method further comprises:

welding the plurality of first reinforcing ribs when welding the upper cover outer periphery boss and the lower cover outer periphery boss.

13. The method according to claim 12 ,

wherein the plurality of first reinforcing ribs are aligned with the upper cover outer periphery boss.

14. The method according to claim 9 ,

wherein a plurality of second reinforcing ribs between the upper cover inner periphery boss and the upper cover inner periphery flange, and

wherein the method further comprises:

welding the plurality of second reinforcing ribs when welding the upper cover inner periphery boss and the lower cover inner periphery boss.
