CN-116806842-B - Nano-silver slow-release particles, preparation method and self-cleaning mask atomizer

Abstract

The invention discloses a nano silver slow-release particle, a preparation method and a self-cleaning mask atomizer, wherein the nano silver slow-release particle consists of 0.1% -5% of silver powder, 20% -50% of sodium hexametaphosphate, 30% -50% of calcium acetate, 1% -10% of zinc oxide and 10% -20% of sodium polyacrylate. The nano silver slow-release particles can release silver ions in the nano material into a water body, and have the advantages of safety in drinking, lasting antibacterial and bacteriostatic effects and the like. The nano silver slow-release particles are fixed in the mask atomizer, silver ions with ppb concentration can be released from the nano silver slow-release particles in water or liquid medicine, and the antibacterial water containing silver ions can be used for efficiently cleaning and antibacterial treatment of an atomizing cup, the mask, an atomizing device and a connecting piece, and can also be drunk or inhaled by people along with the atomizing process. Meanwhile, the antibacterial water body cannot damage the atomizing function of the atomizing device, silver ions remained on the surface after the mask atomizer is flushed by clean water can also keep atomizing equipment clean for a long time, and the practicality is better.

Description

Nano-silver slow-release particles, preparation method and self-cleaning mask atomizer Technical Field The invention relates to the technical field of atomization, in particular to nano silver slow-release particles, a preparation method and a self-cleaning mask atomizer. Background Air pollution, season replacement, and "shoulder friction" are common for patients with respiratory diseases in hospitals. The traditional modes of medication and injection therapy cannot meet various complex patients and diseases. Nebulizers, also known as nebulizers/sputum-resolving machines, are a device for the adjuvant treatment of upper respiratory tract diseases. The medicine solution is atomized into tiny particles by compressed air generated by the atomizer through an inhalation method, enters into respiratory tracts and lungs and is deposited, so that the medicine can quickly and directly reach diseased parts and directly contact with diseased tissues, and the medicine solution has quick response. Thereby achieving rapid and effective treatment effect. The time of taking blood orally or injecting blood is avoided, and the effect can be achieved by using small dosage, so that the systemic administration is avoided, and the side effect of the medicine on human body is avoided, which is particularly important for infants, children and old people. At present, in hospitals, clinics or families, an atomizing cup, an atomizing device, a mask and a connecting piece which are matched with an atomizer are used for disinfection in a disposable or boiling way. The former single use has a great influence on the demand of raw materials and the environment. The latter way of heating to boil is also very inconvenient. And the bacteria are difficult to be killed well, and even the atomization function of the atomized medicine cup is possibly destroyed.
