The present invention relates to a sprayer including a movable antibacterial buoyancy body, and more particularly, to a sprayer comprising a movable antibacterial buoyancy body that includes a silica carrier containing silver nano particles. The movable antibacterial buoyancy body is inserted in the sprayer to restrain the propagation of germs within water stored in the sprayer, and to prevent unpleasant odors. In addition, since the movable antibacterial buoyancy body has a very simple structure, the antibacterial buoyancy body can be easily inserted into the sprayer. Thus, the movable antibacterial buoyancy body can be conveniently used, regardless of the type and form of sprayers, such as the body shape and spray pattern of sprayers. Furthermore, a typical sprayer can be used without modifications. In addition, since the antibacterial buoyancy body can freely float according to the flow of the water, active components of the antibacterial buoyancy body are transferred to all regions of the water, including the central portion and peripheral portion of the water, and thus work in all regions thereof. Moreover, the antibacterial buoyancy body may be fabricated, for example, in a fish shape or a petal shape, to thereby decorate the inside of the sprayer.La présente invention concerne un pulvérisateur comprenant un corps de poussée antibactérien mobile, et plus particulièrement, un pulvérisateur comprenant un corps de poussée antibactérien mobile qui comprend un vecteur de silice contenant des nanoparticules dargent. Le corps de poussée antibactérien mobile est inséré dans le pulvérisateur pour limiter la propagation de germes dans leau stockée dans le pulvérisateur, et pour empêcher les odeurs désagréables. De plus, étant donné que le corps de poussée antibactérien mobile a une structure très simple, le corps de poussée antibactérien peut être facilement inséré dans le pulvérisateur. Ainsi, le corps de poussée antibactérien mobile peut être commodément utilisé, quel
