Positive pressure electric spraying nose washing device Technical Field The invention relates to the technical field of spray nose washing devices, in particular to a positive pressure electric spray nose washing device. Background Nasal irrigation is an effective adjuvant therapy for alleviating symptoms of diseases such as allergic rhinitis and sinusitis. Currently, the main products in the market, such as a manual nasal wash pot and a first-generation electric nasal wash device, have the working principle based on forward pressure flushing, namely, the cleaning liquid is poured into one nostril through manual extrusion or motor driving, flows through the nasal cavity, and naturally flows out of the other nostril or oral cavity through gravity or the pressure of the liquid. However, in the prior art, after the secretions, allergens and other dirt sprayed by the nasal irrigator are mixed with the cleaning liquid in the forward flushing mode, the secretions can only slowly move in the complicated nasal passages and finally be discharged by virtue of the fluidity, and the viscous secretions often form a continuous and firmly-adhered coating layer on the inner wall of the nasal cavity due to the inherent cohesive force and the adhesive force to the mucous membrane.
