In order not to affect the injection molding of the upper shell 1, the wiring harness assembly 6 needs to be fixed and sealed. For this purpose, a first buckle cover 25 is provided in the lower shell 2. The first buckle cover 25 includes a first cover plate 251 and a first threading notch 252. During installation, the first buckle cover 25 is inserted into the first wire entry hole 23.

The sealing plate 531 can cover the second accommodating groove 212, and the locking column 532 can abut against the inner side wall of the second accommodating groove 212. In the embodiment of the utility model, the locking column 532 forms an interference fit with the inner side wall of the second accommodating groove 212 to completely block the second accommodating groove 212.

[0036] In order to facilitate threading, a recessed second wire entry hole 24 is also provided on one side of the lower shell 2 close to the heating film 31.

The second threading notch 262 can provide space for the insertion of the wiring harness assembly 6, so that the wiring harness assembly 6 can pass through the second threading notch 262 and be electrically connected to the seat sensor 42.

[0038] Further, see Figure 3 The side wall of the locking column 532 is provided with a locking rib 533, and the locking rib 533 surrounds the side wall of the locking column 532 and abuts against the inner wall of the second accommodating groove 212. The locking rib 533 can form an interference fit with the inner wall of the second accommodating groove 212, and at the same time, the locking rib 533 can make the fit more stable and tight.

[0039] In order to fix the seating sensor 42, the lower shell 2 further includes a fixing plate 27, one end of which is detachably fixed in the second receiving groove 212, and the fixing plate 27 presses the seating sensor 42 in the second receiving groove 212. A fixing hole is provided at one end of the fixing plate 27, and the fixing plate 27 can be fixed in the second receiving groove 212 by fasteners such as screws, and is also easy to disassemble.

Since the wire diameter of the assembly line 61 is larger than the wire diameter of each bundle of the electronic wire 62, in order to avoid the assembly line 61 protruding from the upper surface of the lower shell 2 after installation, affecting the pasting installation of the heating film 31, the depression depth of the bus slot 221 is greater than the depression depth of the branching slot 222, so as to expand the storage space 21 for the assembly line 61, thereby ensuring the flatness of the upper surface of the lower shell 2.

[0041] See also Figure 2The wiring harness assembly 6 also includes a wiring harness connector 63, which is arranged at the end of the assembly line 61, and the outer wall of the wiring harness connector 63 is provided with a thread.

The wiring harness connector 63 can be placed in the wire hole 28, and the clamping plate 631 can be inserted into the clamping groove 281, so as to fix the wiring harness connector 63, which is convenient for subsequent injection molding. At the same time, it can ensure that the tension that the power cord assembly 7 can withstand after being connected to the wiring harness connector 63 meets the safety requirements.

[0043] See also Figure 1 The heating film 31 is provided with an avoidance hole 311 , and the position of the avoidance hole 311 corresponds to the position of the seat sensor 42 , which can prevent the heating film 31 from interfering with the seat sensor 42 and affecting the normal operation of the seat sensor 42 .

The cushion component 5 performs waterproof sealing on the storage space 21. Since the upper shell 1 and the lower shell 2 are an integral structure formed in one piece, the traditional welding process is eliminated by sequential injection molding, which can shorten the production cycle, improve the overall aesthetics, and improve the waterproof performance.

[0045] Another embodiment of the utility model provides a toilet (not shown in the drawings), comprising the heating seat ring as described above. The heating seat ring can make the upper shell 1 and the lower shell 2 form an integral structure, and the upper shell 1 and the lower shell 2 can be produced by injection molding in sequence.
