[0002] The toilet is one of the essential household items. Existing toilets are basically flush toilets or flush toilets. This type of toilet flushes before and after entering the toilet to maintain the cleanliness of the toilet. Under normal circumstances, there is a little water in the toilet bowl, so that the dirt can be easily and quickly flushed away after entering the toilet. However, this also has certain disadvantages. For example, when defecating, it is easy to splash water, which brings inconvenience to the user; in addition, the toilet of this structure is prone to odor, and the whole bathroom and even the whole house have odor.

[0003] Therefore, foam toilets have appeared on the market. A foam generator is added to the toilet, which usually includes a foaming box and a foaming agent box. A foaming stone is set in the foaming box. The foaming agent and water are pumped into the foaming box to form a mixed liquid, and then air is input into the foaming stone for foaming. The generated foam is sprayed from the output end of the foaming box into the toilet bowl. This method can solve the problem of sewage splashing in the toilet bowl and urine splashing when the user urinates and defecates, and the problem that the smell during urination and defecation cannot be covered in time, affecting air hygiene. The foam can lubricate, clean, sterilize and disinfect the toilet bowl, and block the lower sewage outlet.

[0043] The foaming component 40 is installed on the inner wall of the toilet bowl 14 of the seat body 12 and is partially or completely located below the water seal liquid surface. The foaming component 40 includes a foaming stone 41 and a fixing sleeve 42. The inner wall of the toilet bowl 14 is provided with a mounting port, which is located below the water seal liquid surface, and the fixing sleeve 42 can be completely or partially located below the water seal liquid surface. The fixing sleeve 42 is fixedly penetrated through the mounting port, and the fixing sleeve 42 and the mounting port can be fixed by threaded fitting. The fixing sleeve 42 is provided with a mounting groove 43, which is connected to the toilet bowl 14 and the output end of the exhaust mechanism 50, and the foaming stone 41 is embedded in the mounting groove 43. Then the foaming stone 41 is also located below the water seal liquid surface and contacts with the water seal water 13, and the surface of the foaming stone 41 can protrude from the inner wall of the toilet bowl 14.

[0044] In practical applications, the foam stone 41 is preferably located on the side wall near the flushing port of the toilet bowl 14, close to the front end of the seat 12. The number of foam stones 41 can be one or two, etc., which can be set according to needs, preferably one.

[0045] Furthermore, the foaming component 40 further includes a sealing gasket 45 and a baffle 46. The sealing gasket 45 is installed between the outer wall of the fixing sleeve 42 and the installation opening to play a sealing role, thereby preventing the water seal water 13 from leaking from the fixing sleeve 42. The number of sealing gaskets 45 can be set according to demand. The baffle 46 is spaced apart from the installation groove 43, and the baffle 46 abuts against the outer wall of the toilet bowl to further limit the fixing sleeve 42.
