Abstract

The invention discloses a saline nasal sprayer which comprises a bottle body, a pump and a bottle cap. The pump is installed on the bottle body and used for pumping liquid in the bottle body. The bottle cap is buckled with the bottle body to form a closed containing cavity. The pump is located in the containing cavity. The pump comprises a spray pipe which is provided with a bacteria filtering membrane used for preventing bacteria from entering the bottle body, and the pore diameter of the bacteria filtering membrane is smaller than or equal to 0.22 micrometer. According to the saline nasal sprayer, the bacteria filtering membrane for preventing sucking bacteria back is arranged in the spray pipe, and the diameter of the bacteria filtering membrane is smaller than or equal to 0.22 micrometer so that the liquid can be effectively prevented from being sucked back, and bacteria can be filtered away to prevent secondary pollution.
