Definitions

  • the present disclosure relates to the field of toilet technologies, and more particularly, to a toilet seat.
  • a toilet seat of a toilet is usually formed by connecting upper and lower covers, and a cavity is formed between the upper and lower covers to reduce structural weight and save material cost.
