  • Patent number: 12150428
    Abstract: The flip-type cat litter box includes a cat litter box assembly and a purification device. The cat litter box assembly includes a stainless steel bottom bowl and a top cover of a cat litter box that is disposed on a top of the stainless steel bottom bowl. A pedal is movably embedded on the top cover of the cat litter box, and the pedal is internally provided with a through-hole. After a cat relieves the bowels in the stainless steel bottom bowl and leaves, operations of sterilization and deodorization are performed immediately via an anion generator, an ultraviolet light, and a sensor. This effectively resolves a problem of bacteria and odor of the cat litter box, so that the using is more sanitary. A user toggles the latch catch body to unlock the pedal and flips the pedal upward, to enable the pedal to keep tilted on a top cover of a cat litter box. In addition, a transparent door and the pedal are folded together.

  • Patent number: 11766025
    Abstract: An automatic pet water feeder includes a water replenishing assembly including a bucket body, a bucket cover on a mouth of the bucket body, a silicone plug in the bucket cover, and a movable pin configured to telescopically drive the silicone plug to block and dredge the mouth of the bucket body; and a filter assembly including a shell and a filter element in the shell. One end of the bucket cover is inserted into the shell. The filter element is configured to filter water flowing from the bucket body. The pet water feeder may filter drinking water multiple times through the filter element so that water may be effectively purified. The bucket body may be automatically blocked by gravity through the telescopic movable pin, so that water may not be spilled when being changed.
