[0029] Example 1:

[0030] See Figures 2 to 9 This embodiment relates to a toilet, which includes a toilet body 90 and a toilet seat. The toilet seat is an assembly installed on the toilet body 90. The toilet seat mainly includes a base 80 and a housing 10 fixedly mounted on the base 80. The housing 10 is provided with a filling nozzle 101. A sealing plug 20 is detachably inserted into the filling nozzle 101 to prevent dust and other particles from falling into the filling nozzle 101. A cover 30 is detachably placed on the housing 10 to cover the sealing plug 20, maintaining the toilet's aesthetically pleasing and simple appearance. When foaming agent is needed, the cover 30 is removed, the sealing plug 20 is pulled out, and the foaming agent is poured into the filling nozzle 101. The foaming agent flows along the liquid guide tube 40 into the liquid storage device 50. When the foam shield function is activated, the foaming agent in the liquid storage device 50 is delivered to the foaming device 70 through the liquid supply tube 60. The foaming device 70 foams the water, and the foam flows to the toilet bowl surface to form a foam shield.

[0031] A connector 1 is fixedly mounted on the housing 10, which enables the fixed assembly and interconnection between the filling nozzle 101 and the liquid guide tube 40. A clearance hole is provided on the base 80 to allow space for the liquid guide tube 40 and the connector 1. Considering the installation tolerance between the connector 1 and the base 80, the clearance hole is designed to be relatively large. Waterproof foam 4 is sandwiched between the connector 1 and the base 80 to prevent moisture from entering the toilet seat.

[0032] In this embodiment, the connector 1 has a through hole 17, through which the liquid guide tube 40 passes and is inserted into the liquid filling nozzle 101, and is sealed to the liquid filling nozzle 101. The connector 1 has a insertion groove, in which the liquid filling nozzle 101 is inserted. The insertion groove has multiple protrusions 11 spaced around the liquid filling nozzle 101. The liquid filling nozzle 101 is engaged between the liquid inlet end of the connector 1 and the multiple protrusions 11. The gap between the protrusions 11 and the liquid inlet end of the connector 1 is equal to or slightly less than the wall thickness of the liquid outlet end of the liquid filling nozzle 101, which improves the reliability of the assembly between the liquid filling nozzle 101 and the connector 1 without requiring excessive assembly force. The connector 1 is also fixedly assembled to the housing 10 by clips or screws to ensure the reliability of the assembly of the connector 1. The embodiments of this utility model are not limited to this; those skilled in the art can decide whether to continue using similar methods as needed. Figure 1The design shown is similar to that of the prior art, where the filling nozzle is inserted into the through hole of the connector.

[0033] To facilitate the installation and removal of the liquid guide tube 40, a quick-release fixing device 3 is provided on the connector 1 to fix the liquid guide tube 40 to the connector 1. In this embodiment, the quick-release fixing device 3 includes a retaining ring 31, a retaining spring 32, and a button 33 arranged sequentially along the liquid filling direction. The retaining spring 32 is used to lock the liquid guide tube 40, which passes through the through hole 17 of the connector 1, thus fixing the liquid guide tube 40 to the connector 1. The button 33 is used to push the retaining spring 32, causing the retaining spring 32 to release the liquid guide tube 40. The retaining ring 31 is used to limit the range of motion of the retaining spring 32. See also Figures 7 to 9 ,exist Figure 7 In the middle, the retaining ring 32 is in the state of locking the liquid guide tube 40, thus fixing the liquid guide tube 40 inside the connector 1; in Figure 8 In comparison Figure 7 To remove the liquid guide tube 40, the button 33 was pushed a short distance towards the liquid inlet 101, causing the retaining ring 32 to release the liquid guide tube 40. Because the retaining ring 32 was blocked by the retaining ring 31, the button 33 could not be pushed further towards the liquid inlet 101. Figure 9 In comparison Figure 8 The liquid guide tube 40 is pulled out a certain distance away from the liquid inlet 101. This quick-release fixing device has a simple structure and is easy to operate. The embodiments of this utility model are not limited to this, and those skilled in the art can use other existing quick-release fixing devices as needed.

[0034] See Figure 6 The filling nozzle 101 has a first limiting surface P and a second limiting surface Q arranged sequentially along the filling direction. The first limiting surface P is used to mate with the liquid guide tube 40. When the liquid guide tube 40 is inserted into the filling nozzle 101, the obstruction of the first limiting surface P is felt, indicating that the liquid guide tube 40 has been inserted into place. The sealing ring 2 is sandwiched between the retaining ring 31 and the second limiting surface Q. The sealing ring 2 is press-fitted with the liquid guide tube 40 and the filling nozzle 101 respectively, realizing the sealing between the liquid guide tube 40 and the filling nozzle 101, and between the filling nozzle 101 and the connector 1. The connector 1 has a first limiting part 12, a second limiting part 13 and a third limiting part 14 arranged sequentially along the filling direction. The sealing ring 2 is located between the first limiting part 12 and the second limiting surface Q. The retaining ring 32 is located between the retaining ring 31 and the second limiting part 13. The retaining ring 31 overlaps with the first limiting part 12. The button 33 has a limiting groove 331, and a third limiting part 14 is inserted into the limiting groove 331 to prevent the button 33 from coming off the connector 1. The third limiting part 14 and the limiting groove 331 can move relative to each other, and the button 33 moves closer to or further away from the retaining ring 31 accordingly, so that the liquid guide tube 40 can be quickly installed and removed. See Figure 4The retaining ring 31 has a locking protrusion 311, and the sealing ring 2 has a corresponding locking groove 21. The locking protrusion 311 is locked in the locking groove 21, so that the sealing ring 2 is fixed on the retaining ring 31. The retaining ring 31 has a higher hardness than the sealing ring 2, which can improve the reliability of the sealing ring 2.

[0035] In this embodiment, see Figure 2 The liquid storage device 50 and the foaming device 70 are located inside the tub 90, which helps to improve the compactness of the overall toilet structure and also effectively increases the design space for the toilet seat. The liquid guide pipe 40 passes through the tub 90 and connects to the liquid storage device 50. The embodiments of this utility model are not limited to this, and those skilled in the art can adopt a design where the liquid storage device and the foaming device are located on the toilet seat as needed.
