[0002] The nasal washer is a tool used to clean the nasal cavity. It uses a certain pressure to send saline into the nostrils for cleaning. During the working process, it needs to be equipped with a corresponding replacement connector;

[0003] Most of the existing constant temperature nasal washers require users to perform tedious installation work, and the user's hands may become unhygienic during the docking process;

[0004] For example, a nasal wash device with publication number CN102462606A. The nasal wash device is composed of a nasal plug 1, a wash liquid catheter 3, a recovery liquid catheter 2, a one-way water valve 4, a one-way air valve 7, a nasal wash liquid bottle 6 and a recovery liquid bottle 5, so that the nasal wash liquid can flow in one direction and enter the recovery bottle, reducing the pollution of the nasal wash liquid to the surrounding environment, and avoiding possible infection caused by contamination of the nasal plug and the bottle. The flushing speed can also be controlled by the user's hand strength, which is simple to operate and very comfortable;

[0005] Another example is a nasal wash device with publication number CN107822863A, which includes: a container unit for containing liquid; a cover body for sealing the container unit; and a cleaning tube assembly, one end of which passes through the cover body and is connected to the container unit; a receiving part is provided in the cover body, and the receiving part includes: a chamber for containing a solute for a nasal wash; and a packaging member for removably sealing the chamber. The receiving part is added to the cover body, so that the nasal wash device can store both the solute and the solvent, making it more convenient to carry;
