Description

Technical Field

[0001] This invention relates to a toilet seat with improved seating comfort and a method for manufacturing the same. More specifically, it relates to a toilet seat and a method for manufacturing the same, which improves seating comfort so that users can use the toilet seat comfortably without discomfort, and reduces manufacturing time and breakage rate during the manufacturing process. Background Technology

[0002] The toilet seat is installed on the upper part of the toilet bowl for the user's buttocks to rest on, and it is usually divided into an upper seat and a lower seat.

[0003] Traditional toilet seats are injection molded from synthetic resin, but the inner side of the seat does not have reinforcing ribs, or the reinforcing ribs abut against the upper part of the seat, which makes the upper part of the seat easy to break or unable to deform, thus causing inconvenience during use.

[0004] In addition, in existing toilet seats, the upper and lower seats are joined together by welding. Since the toilet seat is injection molded from synthetic resin, burrs will be generated during the welding process.

[0005] Uneven and rough burrs formed on the mating surface may cause discomfort to users when using toilet seats.

[0006] Therefore, it is necessary to remove burrs. However, manual burr removal requires skilled workers to operate by hand, which is not only time-consuming, but also increases the breakage rate during the removal process, resulting in a large loss of resources. Summary of the Invention [Technical Issues]

[0007] This invention is proposed to solve the above-mentioned problems. Its purpose is to make users feel comfortable when using toilet seats, while shortening the manufacturing time and reducing the breakage rate.

[0008] The technical problems to be solved by the present invention are not limited to those mentioned above. Other technical problems not mentioned can be clearly understood by those skilled in the art from the following description. [Technical Solution]

Figure 6 This is a view showing the first-1 extension, the first-2 extension, the second-1 extension, and the second-2 extension, which are burrs generated when the upper and lower seat rings are fused together in a toilet seat ring with improved seating comfort according to an embodiment of the present invention. Figure 7 This is a view showing the state after the first-1 extension, the first-2 extension, the second-1 extension, and the second-2 extension in a toilet seat with improved seating comfort according to an embodiment of the present invention have been removed.

[0036] Reference Figures 1 to 7 According to an embodiment of the present invention, a toilet seat with improved sitting comfort allows the user to feel comfortable when using the toilet seat due to the improved sitting comfort.

[0037] Therefore, a toilet seat with improved seating comfort may include a lower seat 10 and an upper seat 20.

[0038] The lower seat ring 10 can be placed on the upper part of the toilet.

[0039] The lower seat ring 10 has a predetermined thickness, is annular, and has a mounting portion 11 recessed at the upper inner edge and upper outer edge.

[0040] In addition, the lower seat ring 10 may have an elliptical lower discharge hole 14 formed on its inner side.

[0041] The lower seat ring 10 can be combined with the upper seat ring 20.

[0042] The upper seat ring 20 has a predetermined thickness, is annular, and has protrusions 21 extending from the lower inner edge and the lower outer edge toward the mounting portion 11.

[0043] In addition, the upper seat ring 20 may have an elliptical upper discharge hole 24 formed on its inner side, which corresponds to the lower discharge hole 14 of the lower seat ring 10.

[0044] The lower seat ring 10 and the upper seat ring 20 may respectively form a first-1 extension 12-1, a first-2 extension 12-2, a second-1 extension 22-1, and a second-2 extension 22-2 with rectangular cross sections on the inner and outer sides.

[0045] In the rectangular cross-section, the longitudinal length is greater than the transverse length, and the vertical surface is attached to the inner and outer sides of the lower seat ring 10 and the upper seat ring 20.

[0046] Specifically, in the lower seat ring 10, a first extension 12-1 with a rectangular cross-section is formed extending inward from the lower side of the mounting portion 11 formed on the upper inner edge, and a first extension 12-2 with a rectangular cross-section is formed extending outward from the lower side of the mounting portion 11 formed on the upper outer edge.

[0047] In the upper seat ring 20, a second-1 extension 22-1 with a rectangular cross-section extends inward from the side of the protrusion 21 at the lower inner edge, and a second-2 extension 22-2 with a rectangular cross-section extends outward from the side of the protrusion 21 at the lower outer edge.

[0048] Here, the upper surface of the first-1 extension 12-1 of the lower seat ring 10 is flush with the upper surface of the upper inner edge of the lower seat ring 10; the upper surface of the first-2 extension 12-2 is flush with the upper surface of the upper outer edge of the lower seat ring 10.

[0049] The lower surface of the second-1 extension 22-1 of the upper seat ring 20 is flush with the lower surface of the protrusion 21 on the lower inner edge of the upper seat ring 20; the lower surface of the second-2 extension 22-2 is flush with the lower surface of the protrusion 21 on the lower outer edge of the upper seat ring 20.

[0050] The lower seat ring 10 and the upper seat ring 20 can be fused together.

[0051] Specifically, the placement part 11 is fused with the protrusion 21, the first-1 extension 12-1 is fused with the second-1 extension 22-1, and the first-2 extension 12-2 is fused with the second-2 extension 22-2.

[0052] The first-1 extension 12-1 and the first-2 extension 12-2 of the lower seat ring 10 and the second-1 extension 22-1 and the second-2 extension 22-2 of the upper seat ring 20 are removed after the mounting portion 11 and the protrusion 21 are welded together.

[0053] Specifically, during the welding process between the first-1 extension 12-1 and the second-1 extension 22-1, burrs are generated on one side of the first-1 extension 12-1 and the second-1 extension 22-1, which have burrs, are removed from the placement portion 11 and the protrusion 21.

[0054] Furthermore, during the welding process between the first-2 extension 12-2 and the second-2 extension 22-2, burrs are generated on one side of the first-2 extension 12-2 and the second-2 extension 22-2, which have burrs, are removed from the placement portion 11 and the protrusion 21.

[0055] The height of the upper seat ring 20 can gradually increase from the inside to the outside.

[0056] The upper seat ring 20 has a cross-section that is rotated to make the opening face downwards in a U-shape, but the height of one side can be higher than that of the other side.

[0057] The cross-section of the upper seat ring 20 is annular, with the inner side lower and the outer side higher.

[0058] Therefore, the user's buttocks can be easily placed on the upper part of the upper seat ring 20, allowing for comfortable use.

[0059] A heating wire 30 may be provided on the lower inner surface of the upper seat ring 20.

[0060] The heating wire 30 is closely attached to the lower inner surface of the upper seat ring 20, so that heat is transferred quickly and the thermal efficiency is high, and the user can feel comfortable and pleasant when using it.

[0061] The upper seat ring 20 is joined to the lower seat ring 10 at the lower part, and the upper part of the lower seat ring 10 may have multiple reinforcing ribs 13.

[0062] Multiple reinforcing ribs 13 are vertically arranged in the upper part in the form of plates with a predetermined thickness, and their upper surfaces are spaced apart from the lower inner surface of the upper seat ring 20 by a predetermined first distance D1.

[0063] In addition, among the multiple reinforcing ribs 13, the interval between adjacent reinforcing ribs 13 can be a preset second distance D2.

[0064] Multiple reinforcing ribs 13 may correspond to heating lines 30 arranged on the lower inner surface of the upper seat ring 20, and be formed at positions where heating lines 30 are not arranged.

[0065] The multiple reinforcing ribs 13 can prevent the upper seat ring 20 from being damaged by the user's weight when the user's buttocks are placed on it.

[0066] More specifically, since the upper seat ring 20 is an injection-molded material with a predetermined thickness, the upper seat ring 20 may deform due to the user's weight when the user places it on the upper part.

[0067] To prevent the upper seat ring 20 from breaking due to its weight and to improve seating comfort, a plurality of reinforcing ribs 13 are formed on the upper part of the lower seat ring 10. The plurality of reinforcing ribs 13 are spaced apart from the lower inner surface of the upper seat ring 20 by a first distance D1, thereby preventing the upper seat ring 20 from deforming beyond the first distance D1 and thus preventing breakage.

[0068] Furthermore, when the multiple reinforcing ribs 13 are in close contact with and abut against the lower inner surface of the upper seat ring 20, the shape of the upper seat ring 20 will not deform when the user places it on the upper part of the upper seat ring 20, which may cause discomfort to the user.

[0069] Therefore, the upper seat ring 20 is separated from the multiple reinforcing ribs 13 by a preset first distance D1, thereby improving the seating comfort and allowing the user to use it comfortably.

[0070] In other words, the lower inner surface of the upper seat ring 20 is separated from the multiple reinforcing ribs 13 of the lower seat ring 10 by a first distance D1, thereby limiting the deformation of the upper seat ring 20 to no more than the first distance D1, so that the upper seat ring 20 will not be damaged when the user places it on the upper seat ring 20. At the same time, the deformation of the first distance D1 improves the sitting feel, so that it can be used comfortably.

[0071] In addition, the multiple reinforcing ribs 13 are formed such that the interval between adjacent reinforcing ribs 13 is a second distance D2, thereby distributing the weight and providing cushioning when the user places it on the upper part of the upper seat ring 20, thereby preventing damage to the upper seat ring 20 and the lower seat ring 10.

[0072] Multiple protrusions 15 can be formed on the lower part of the lower seat ring 10.

[0073] When the lower seat ring 10 is placed on the upper part of the toilet, the multiple protrusions 15 maintain a certain distance between the lower seat ring 10 and the upper part of the toilet, thereby preventing bacteria from growing on the lower part of the lower seat ring 10.

[0074] A hinge portion 23 can be formed extending from the rear of the upper seat ring 20.

[0075] The hinge part 23 can be combined with the toilet seat (not shown) to allow the toilet seat (not shown) to rotate.

[0076] On the other hand, the manufacturing method of a toilet seat with improved sitting comfort will be explained below.

[0077] Figure 8 This is a flowchart illustrating a method for manufacturing a toilet seat with improved seating comfort according to an embodiment of the present invention.

[0078] Reference Figure 8 The present invention includes: a lower seat ring 10 injection molding step S1; an upper seat ring 20 injection molding step S2; a step S3 of fitting and joining the lower seat ring 10 and the upper seat ring 20 together; a step S4 of welding the lower seat ring 10 and the upper seat ring 20 together; and a step S5 of removing the first-1 extension 12-1, the first-2 extension 12-2, the second-1 extension 22-1 and the second-2 extension 22-2 of the lower seat ring 10 and the upper seat ring 20 respectively after welding.

[0079] In the injection molding step S1, the lower seat ring 10 is annular, with a recessed placement portion 11 formed at the upper inner edge and upper outer edge. A first extension portion 12-1 extends inward from the lower side of the placement portion 11 at the upper inner edge, and a first extension portion 12-2 extends outward from the lower side of the placement portion 11 at the upper outer edge.

[0080] In the injection molding step S2, the upper seat ring 20 is ring-shaped, with a protrusion 21 protruding from the lower inner edge and the lower outer edge toward the placement part 11. A second extension 22-1 extends inward from the side of the protrusion 21 on the lower inner edge, and a second extension 22-2 extends outward from the side of the protrusion 21 on the lower outer edge.

[0081] In step S3, which involves fitting the lower seat ring 10 and the upper seat ring 20 together, the placement portion 11 abuts against the protrusion 21, the first-1 extension portion 12-1 abuts against the second-1 extension portion 22-1, and the first-2 extension portion 12-2 abuts against the second-2 extension portion 22-2, thereby fitting the lower seat ring 10 and the upper seat ring 20 together.

[0082] In step S4, which involves welding the lower seat ring 10 to the upper seat ring 20, the placement part 11 is welded to the protrusion 21, the first-1 extension 12-1 is welded to the second-1 extension 22-1, and the first-2 extension 12-2 is welded to the second-2 extension 22-2.

[0083] In step S5, which removes the extensions 12-1, 12-2, 22-1, and 22-2 of the lower seat ring 10 and the upper seat ring 20 after welding, the first-1 extension 12-1, the second-1 extension 22-1, the first-2 extension 12-2, and the second-2 extension 22-2, which have burrs on one side during the welding step, are removed from the placement part 11 and the protrusion 21.

[0084] The following is a detailed explanation of each step.

[0085] First, the lower seat ring 10 is injection molded, and a mounting portion 11 is formed by recessing the upper inner edge and the upper outer edge. A first extension portion 12-1 is formed by extending the lower side of the mounting portion 11 on the upper inner edge inward, and a first extension portion 12-2 is formed by extending the lower side of the mounting portion 11 on the upper outer edge inward.

[0086] In order to be able to combine with the lower seat ring 10, the upper seat ring 20 is injection molded, and a protrusion 21 is formed on the lower inner edge and the lower outer edge protruding toward the mounting part 11. A second-1 extension 22-1 is formed by extending inward from the side of the protrusion 21 on the lower inner edge, and a second-2 extension 22-2 is formed by extending outward from the side of the protrusion 21 on the lower outer edge.

[0087] The lower seat ring 10 and the upper seat ring 20 formed in this way abut the placement part 11 against the protrusion 21, abut the first-1 extension 12-1 against the second-1 extension 22-1 against the first-2 extension 12-2 against the second-2 extension 22-2, and fit the two together.

[0088] After the parts are joined together, the placement part 11 and protrusion 21 of the lower seat ring 10 and the upper seat ring 20, the first extension 12-1 and the second extension 22-1, and the first extension 12-2 and the second extension 22-2 are respectively welded together.

[0089] Therefore, a first-1 extension 12-1, a first-2 extension 12-2, a second-1 extension 22-1, and a second-2 extension 22-2 are formed in the lower seat ring 10 and the upper seat ring 20, respectively, and burrs are formed on these first-1 extension 12-1, first-2 extension 12-2, second-1 extension 22-1, and second-2 extension 22-2.

[0090] Here, ultrasonic welding is used as the welding method.

[0091] During the welding process, burrs are generated on one side of each of the 1-1 extension 12-1, 1-2 extension 12-2, 2-1 extension 22-1 and 2-2 extension 22-2 that are being welded.

[0092] Here, burrs are generated after welding. The surface of the burrs is not smooth and is rough, which may cause discomfort when in contact with the user's skin.

[0093] Therefore, the first-1 extension 12-1, the second-1 extension 22-1, the first-2 extension 12-2, and the second-2 extension 22-2 are removed from the mounting portion 11 and the protrusion 21.

[0094] Therefore, the first-1 extension 12-1, the second-1 extension 22-1, the first-2 extension 12-2 and the second-2 extension 22-2 are removed by automated mechanical equipment, so that no manual operation is required when removing burrs, thereby reducing the breakage rate and shortening the manufacturing time, which is effective.

[0095] On the other hand, the first-1 extension, the first-2 extension, the second-1 extension, and the second-2 extension of another embodiment of the present invention will be described below.

[0096] Figure 9 This is a view showing the first-1 extension, the first-2 extension, the second-1 extension, and the second-2 extension according to another embodiment of the present invention.

[0097] The first-1 extension, the first-2 extension, the second-1 extension, and the second-2 extension according to another embodiment of the present invention are identical in shape to the first-1 extension, the first-2 extension, the second-1 extension, and the second-2 extension according to one embodiment of the present invention, and therefore, repeated descriptions are omitted.

[0098] Reference Figure 9 According to another embodiment of the present invention, the cross-sections of the first-1 extension 12-1, the first-2 extension 12-2, the second-1 extension 22-1 and the second-2 extension 22-2 may be in the shape of a right triangle.

[0099] The cross-section of the extension 12-1 is a right triangle, and the cross-sectional area gradually narrows from the top to the bottom. The vertical plane of this right triangle fits against the lower side of the mounting portion 11 on the upper inner edge of the lower seat ring 10, and can extend inward.

[0100] The cross-section of the first-second extension 12-2 is a right-angled triangle, and the cross-sectional area gradually narrows from the top to the bottom. The vertical plane of this right-angled triangle fits against the lower side of the mounting portion 11 formed on the upper outer edge of the lower seat ring 10, and can extend outward.

[0101] The cross-section of the extension 22-1 is a right triangle, and the cross-sectional area gradually widens from the top to the bottom. The vertical plane of this right triangle fits against the side of the protrusion 21 formed on the lower inner edge of the upper seat ring 20, and can extend inward.

[0102] The cross-section of the extension 22-2 is a right triangle, and the cross-sectional area gradually widens from the top to the bottom. The vertical plane of the right triangle fits the side of the protrusion 21 formed on the lower outer edge of the upper seat ring 20 and can extend outward.

[0103] The upper surface of the first-1 extension 12-1 is flush with the upper surface of the placement portion 11 on the upper inner edge of the lower seat ring 10; the upper surface of the first-2 extension 12-2 is flush with the upper surface of the placement portion 11 on the upper outer edge of the lower seat ring 10.

[0104] The lower surface of the 2-1 extension 22-1 is flush with the lower surface of the protrusion 21 on the lower inner edge of the upper seat ring 20; the lower surface of the 2-2 extension 22-2 is flush with the lower surface of the protrusion 21 on the lower outer edge of the upper seat ring 20.

[0105] The first-1 extension 12-1, the first-2 extension 12-2, and the second-1 extension 22-1 and the second-2 extension 22-2 of the upper seat ring 20 are removed after the mounting portion 11 and the protrusion 21 are welded together.

[0106] Specifically, during the welding process between the first-1 extension 12-1 and the second-1 extension 22-1, burrs are generated on one side of the first-1 extension 12-1 and the second-1 extension 22-1, which have burrs, are removed from the placement portion 11 and the protrusion 21.

[0107] Furthermore, during the welding process between the first-2 extension 12-2 and the second-2 extension 22-2, burrs are generated on one side of the first-2 extension 12-2 and the second-2 extension 22-2, which have burrs, are removed from the placement portion 11 and the protrusion 21.

[0108] Therefore, according to another embodiment, the cross-sectional areas of the first-1 extension 12-1, the first-2 extension 12-2, the second-1 extension 22-1, and the second-2 extension 22-2 are smaller, thereby reducing the amount of waste of the first-1 extension 12-1, the first-2 extension 12-2, the second-1 extension 22-1, and the second-2 extension 22-2 that are discarded after the lower seat ring 10 and the upper seat ring 20 are welded.

[0109] On the other hand, the lower seat ring according to another embodiment of the present invention will be described below.

[0110] Figure 10 This is a view showing the state in which a first support portion and a second support portion are formed in the lower seat ring according to another embodiment of the present invention.

[0111] According to another embodiment of the present invention, the lower seat ring is formed only with a first support portion and a second support portion, compared with the lower seat ring according to one embodiment. Other constituent elements are the same, so repeated description is omitted.

[0112] Reference Figure 10 According to another embodiment of the present invention, the lower seat ring 10 of the toilet seat ring with improved sitting comfort may be further formed with a first support portion 16-1 and a second support portion 16-2.

[0113] The first support portion 16-1 is formed on the lower seat ring 10 and is located below the first-1 extension portion 12-1; the second support portion 16-2 is formed on the lower seat ring 10 and is located below the first-2 extension portion 12-2.

[0114] The first support portion 16-1 is plate-shaped with a predetermined thickness and can be formed to have a width greater than that of the first-1 extension portion 12-1.

[0115] The second support portion 16-2 is plate-shaped with a predetermined thickness and can be formed to have a width greater than that of the first-second extension portion 12-2.

[0116] The first support portion 16-1 and the second support portion 16-2 can prevent the first-1 extension portion 12-1, the second-1 extension portion 22-1, the first-2 extension portion 12-2 and the second-2 extension portion 22-2 from melting and flowing down during the welding process between the lower seat ring 10 and the upper seat ring 20.

[0117] Specifically, when the lower seat ring 10 and the upper seat ring 20 are fused together, the placement part 11 and the protrusion 21 are fused together, the first-1 extension 12-1 and the second-1 extension 22-1 are fused together, and the first-2 extension 12-2 and the second-2 extension 22-2 are fused together.

[0118] During the welding process, the first extension 12-1, the second extension 22-1, the first extension 12-2, and the second extension 22-2 may melt. The first support 16-1 and the second support 16-2 are closely attached to the lower part of the first extension 12-1 and the first extension 12-2 to prevent melting and dripping.

[0119] More specifically, the first support portion 16-1 is formed from the lower side of the mounting portion 11 formed inside the lower seat ring 10 in an inward direction, and is closely attached to the lower part of the first-1 extension portion 12-1 for positioning, thereby preventing the molten first-1 extension portion 12-1 and second-1 extension portion 22-1 from flowing to the lower part of the first support portion 16-1 during the welding process of the first-1 extension portion 12-1 and the second-1 extension portion 22-1.

[0120] The second support portion 16-2 is formed outward from the lower side of the mounting portion 11 formed on the outer side of the lower seat ring 10, and is closely attached to the lower part of the first-2 extension portion 12-2 for positioning. In this way, during the welding process of the first-2 extension portion 12-2 and the second-2 extension portion 22-2, the molten first-2 extension portion 12-2 and the second-2 extension portion 22-2 can be prevented from flowing to the lower part of the second support portion 16-2.

[0121] Furthermore, the first support portion 16-1 and the second support portion 16-2 are formed on the lower seat ring 10. However, during the welding process between the lower seat ring 10 and the upper seat ring 20, in order not to melt together with the first-1 extension portion 12-1, the second-1 extension portion 22-1, the first-2 extension portion 12-2 and the second-2 extension portion 22-2, the first support portion 16-1 and the second support portion 16-2 can be formed of a different material than the first-1 extension portion 12-1 and the first-2 extension portion 12-2.

[0122] The first support portion 16-1 and the second support portion 16-2 can be removed after the lower seat ring 10 and the upper seat ring 20 are welded together.

[0123] Specifically, the first extension 12-1 may melt and flow down during the welding process with the second extension 22-1, but the first support portion 16-1 formed on the lower seat ring 10 supports the first extension 12-1 and the second extension 22-1 from below, thereby preventing it from flowing down. When the first extension 12-1 and the second extension 22-1 are removed from the mounting portion 11 and the protrusion 21, the first support portion 16-1 can also be removed together.

[0124] Furthermore, the first-2 extension 12-2 may melt and flow down during the welding process with the second-2 extension 22-2, but the second support 16-2 formed on the lower seat ring 10 supports the first-2 extension 12-2 and the second-2 extension 22-2 from below, thereby preventing it from flowing down. When the first-2 extension 12-2 and the second-2 extension 22-2 are removed from the mounting portion 11 and the protrusion 21, the second support 16-2 can also be removed together.

[0125] Therefore, the melting range of the first-1 extension 12-1, the second-1 extension 22-1, the first-2 extension 12-2 and the second-2 extension 22-2 can be limited, thereby avoiding the additional process of removing the first-1 extension 12-1, the second-1 extension 22-1, the first-2 extension 12-2 and the second-2 extension 22-2.

[0126] Figure 11 This is a view showing a first support portion and a second support portion according to another embodiment of the present invention.

[0127] The first support portion and the second support portion according to another embodiment of the present invention are the same as the first support portion and the second support portion according to one embodiment, except for their shape. Therefore, repeated descriptions are omitted.

[0128] Reference Figure 11 According to another embodiment of the present invention, the first support portion 16-1 and the second support portion 16-2 can be formed in different shapes.

[0129] The first support portion 16-1 is formed on the lower seat ring 10 and is located below the first-1 extension portion 12-1; the second support portion 16-2 is formed on the lower seat ring 10 and is located below the first-2 extension portion 12-2.

[0130] The first support portion 16-1 is plate-shaped with a predetermined thickness, and its width is greater than the width of the first-1 extension portion 12-1, and it can be formed such that one end bends upward.

[0131] The second support portion 16-2 is plate-shaped with a predetermined thickness, and its width is greater than that of the first-second extension portion 12-2. It can be formed such that one end bends upward.

[0132] The first support portion 16-1 and the second support portion 16-2 can prevent the first-1 extension portion 12-1, the second-1 extension portion 22-1, the first-2 extension portion 12-2 and the second-2 extension portion 22-2 from melting and flowing down during the welding process between the lower seat ring 10 and the upper seat ring 20.

[0133] Specifically, when the lower seat ring 10 and the upper seat ring 20 are fused together, the placement part 11 and the protrusion 21 are fused together, the first-1 extension 12-1 and the second-1 extension 22-1 are fused together, and the first-2 extension 12-2 and the second-2 extension 22-2 are fused together.

[0134] During each welding process, the first extension 12-1, the second extension 22-1, the first extension 12-2, and the second extension 22-2 may melt. The first support 16-1 and the second support 16-2 are closely attached to the lower part of the first extension 12-1 and the first extension 12-2 to prevent melting and dripping.

[0135] More specifically, the first support portion 16-1 is formed from the lower side of the mounting portion 11 formed inside the lower seat ring 10 in an inward direction, and is closely attached to the lower part of the first-1 extension portion 12-1 for positioning, thereby preventing the molten first-1 extension portion 12-1 and second-1 extension portion 22-1 from flowing to the lower part of the first support portion 16-1 during the welding process of the first-1 extension portion 12-1 and the second-1 extension portion 22-1.

[0136] The second support portion 16-2 is formed outward from the lower side of the mounting portion 11 formed on the outside of the lower seat ring 10, and is closely attached to the lower part of the first-2 extension portion 12-2 for positioning. In this way, during the welding process of the first-2 extension portion 12-2 and the second-2 extension portion 22-2, the molten first-2 extension portion 12-2 and the second-2 extension portion 22-2 can be prevented from flowing to the lower part of the second support portion 16-2.

[0137] Furthermore, the first support portion 16-1 and the second support portion 16-2 are formed on the lower seat ring 10. However, during the welding process between the lower seat ring 10 and the upper seat ring 20, in order not to melt together with the first-1 extension portion 12-1, the second-1 extension portion 22-1, the first-2 extension portion 12-2 and the second-2 extension portion 22-2, the first support portion 16-1 and the second support portion 16-2 can be formed of a different material than the first-1 extension portion 12-1 and the first-2 extension portion 12-2.

[0138] The first support portion 16-1 and the second support portion 16-2 can be removed after the lower seat ring 10 and the upper seat ring 20 are welded together.

[0139] Specifically, the first extension 12-1 may melt and flow down during the welding process with the second extension 22-1, but the first support portion 16-1 formed on the lower seat ring 10 supports the first extension 12-1 and the second extension 22-1 from below, thereby preventing it from flowing down. When the first extension 12-1 and the second extension 22-1 are removed from the mounting portion 11 and the protrusion 21, the first support portion 16-1 can also be removed together.

[0140] Furthermore, the first-2 extension 12-2 may melt and flow down during the welding process with the second-2 extension 22-2, but the second support 16-2 formed on the lower seat ring 10 supports the first-2 extension 12-2 and the second-2 extension 22-2 from below, thereby preventing it from flowing down. When the first-2 extension 12-2 and the second-2 extension 22-2 are removed from the mounting portion 11 and the protrusion 21, the second support 16-2 can also be removed together.

[0141] Therefore, when the first-1 extension 12-1, the second-1 extension 22-1, the first-2 extension 12-2 and the second-2 extension 22-2 melt, because one end of the first support 16-1 and the second support 16-2 bends upward, even if more melts, it can prevent it from flowing further downward.

[0142] Therefore, the additional process of removing the first-1 extension 12-1, the second-1 extension 22-1, the first-2 extension 12-2, and the second-2 extension 22-2 can be prevented.

While specific terminology is used herein, it is for descriptive purposes only and not intended to limit the meaning or scope of the invention as set forth in the claims. Therefore, those skilled in the art will understand that various modifications and other equivalent embodiments can be made therein. Consequently, the essential scope of protection of this invention should be determined by the technical concept of the appended claims.
