Bactericide slow-release device

The utility model belongs to the technical field of bactericide slow release, and particularly relates to a bactericide slow release device which comprises a slow release cylinder and a placing cylinder, the top of the slow release cylinder is provided with a limiting groove, the side wall of the placing cylinder is provided with a limiting ring corresponding to the limiting groove, the limiting ring is embedded in the limiting groove, and the limiting ring is connected with the placing cylinder. A first through hole is formed in the side wall of the slow-release barrel, and a second through hole is formed in the side wall of the placement barrel. In the application file, under the condition that a water system flows, the contact path of water flow and the bactericide is increased, the slow-release path is increased, and the action time of the bactericide is prolonged, so that the slow-release effect is improved; the sterilization effect of slow release of the bactericide on a water system is facilitated. 本实用
