The present invention belongs to the technical field of electrolytic disinfection, and discloses an electrolytic salting device, disinfection equipment and electrolytic salting control method. The salting device includes a liquid storage container, a salt warehouse and at least one water-absorbing slow-release component. The water-absorbing slow-release component has a first end and a second end. The first end extends into the salt warehouse and contacts the salt particles in the salt warehouse, and the second end extends into the liquid storage container and contacts the liquid in the liquid storage container. After the second end contacts the liquid, the liquid moves toward the first end under capillary action, and the soaked first end dissolves the salt particles around it.
