[0023] To further illustrate the embodiments, the utility model provides drawings. These drawings are part of the disclosure of the utility model, mainly used to illustrate the embodiments, and can be combined with the related description of the specification to explain the operation principle of the embodiments. With reference to these contents, those skilled in the art should understand other possible embodiments and advantages of the utility model. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0024] ​In the description of the present application, the terms "upper", "lower", "left", "right", "front", "back" and other orientation or position relationships are based on the orientation or position relationships shown in the drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0025] The utility model is further illustrated in conjunction with the drawings and specific embodiments.

[0026] Referring to Figures 1 to 5 The heating inner membrane assembly 20 includes a heating film 23, a bottom shell 21 and an upper cover 22. The heating film 23 is arranged between the bottom shell 21 and the upper cover 22, and the bottom shell 21 and the upper cover 22 are fixedly connected. The seat ring body 10 is integrally coated on the outer surface of the heating inner membrane assembly 20 (i.e. the outer surface formed after the bottom shell 21 and the upper cover 22 are assembled) by injection molding. That is, after the assembly of the heating inner membrane assembly 20 is completed, it is placed in an injection mold, and the seat ring body 10 is formed directly on the basis of the heating inner membrane assembly 20 by injection molding. In this way, the outer surface of the heating seat ring has no joint gap, achieving smooth transition.

[0027] With the above structure, the heating film 23 is arranged between the bottom shell 21 and the upper cover 22, and assembly and protection are achieved through the cooperation of the bottom shell 21 and the upper cover 22. It can avoid damage to the seat ring body 10 during injection molding. The seat ring body 10 is integrally coated on the outer surface of the heating inner membrane assembly 20 by injection molding, achieving the overall appearance of the heating seat ring and ensuring the safety of use without the risk of electric leakage. Since there is no joint gap, cleaning is also simple and convenient.

[0028] Specifically, the outer shape of the heating inner membrane assembly 20 is basically the same as that of the prepared seat ring finished product, and is a hollow "O" shape structure. The outer shape of the heating film 23 is also a hollow "O" shape structure. In this way, the heating film 23 can be basically distributed in the full segment position of the seat ring body 10, ensuring uniform heating of the seat ring.

[0029] Further, in order to make the assembly of the heating film 23 more accurate, in the present embodiment, a positioning groove 221 is formed on the upper cover 22, and the heating film 23 is positioned and assembled in the positioning groove 221, achieving accurate assembly of the heating film 23. Of course, in other embodiments, the positioning groove 221 can also be provided on the bottom shell 21.

[0030] The bottom shell 21 and the upper cover 22 are fixed by welding, and the fixing is firm. Specifically, the inner and outer peripheries of the upper cover 22 are both provided with a welding step surface 222, that is, the welding step surface 222 is located at the inner and outer peripheries of the positioning groove 221; the inner and outer peripheries of the bottom shell 21 are both provided with an abutting convex rib 211, the abutting convex rib 211 abuts on the welding step surface 222 of the upper cover 22 and is welded and fixed, so that the inside can be well sealed. The high-temperature plastic liquid is prevented from penetrating into the inside of the heating inner membrane assembly 20 when the seat ring body 10 is injection molded, and the heating film 23 is prevented from being damaged. Of course, in other embodiments, the bottom shell 21 and the upper cover 22 can also be fixed by clamping or adhesive bonding and the like.

[0031] Further, the heating inner membrane assembly 20 further comprises a seat inductor 24; the seat inductor 24 is also arranged between the bottom shell 21 and the upper cover 22. In this embodiment, the heating film 23 is provided with a gap 231, and the seat inductor 24 is located in the gap 231, so that the heating film 23 and the seat inductor 24 do not interfere with each other. The seat inductor 24 is used for detecting whether a person is seated and outputting a signal.

[0032] Specifically, one of the more preferred setting modes is that the heating film 23 has a first lead-out wire, and the seat inductor 24 has a second lead-out wire; the first lead-out wire and the second lead-out wire both extend out of the seat ring body 10 and are used for being connected with an external control box to realize power supply and signal transmission. For example, after the seat inductor 24 senses that a person is seated, a signal is transmitted to the external control box, and the external control box controls the heating film 23 to heat; when the seat inductor 24 senses that no one is seated, a signal is transmitted to the external control box, and the external control box controls the heating film 23 to stop heating. Of course, in other embodiments, it is not limited to this, for example, a control box can also be arranged in the bottom shell 21 and the upper cover 22, the control box has a storage battery, and the storage battery is charged by a wireless charging mode; the control mode is referred to the above. In this way, the lead-out of the wire is avoided. Alternatively, the seat inductor 24 is not used, and a manual switch is used to control the working of the heating film 23, and the like.

[0033] Further, the present embodiment also provides a toilet cover assembly, which comprises a hinged seat and a seat ring and a cover plate hingedly arranged on the hinged seat; wherein the seat ring is the traceless heating seat ring.

[0034] Although the utility model is specifically shown and introduced in combination with the preferred embodiments, it should be understood by those skilled in the art that various changes can be made to the utility model in form and details without departing from the spirit and scope of the utility model defined in the appended claims, and all of them are within the protection scope of the utility model.
