The ampoule A is filled with liquid or low-viscosity cosmetics or medicines, the cosmetics or the medicines flow into the spraying assembly through the liquid inlet channel 21, the cosmetics or the medicines are atomized by the spraying assembly, and the atomized cosmetics or the medicines are sprayed out from the nozzle 13. The liquid is taken by adopting the mode that the liquid inlet pricker 2 punctures the ampoule A, the whole opening of the ampoule A is prevented from being opened, so that the contact between cosmetics or medicines inside the ampoule A and the air is effectively limited, and the bacterial breeding inside the ampoule A is reduced. The slender liquid inlet channel 21 limits the liquid outlet speed, ensures the dispersion uniformity of cosmetics or medicines on the surface of the skin in a spraying mode of the spraying assembly, reduces the waste of the cosmetics or medicines, avoids hands from directly contacting the liquid in the shell 1, and reduces the pollution in the ampoule A.

The ampoule a is inverted at the mounting port 12 and the liquid in the ampoule a flows by hydraulic pressure against atmospheric pressure to the spray assembly. Along with the reduction of the liquid in the ampoule A, the hydraulic pressure is reduced, and the liquid in the ampoule A is difficult to flow out gradually. In order to solve the problems, the liquid inlet pricker 2 is further provided with a ventilation channel 22, one end of the ventilation channel 22 is positioned in the ampoule A, the other end of the ventilation channel 22 is communicated to the atmosphere or a pressure pump, when liquid in the ampoule A is gradually reduced, the atmosphere or the pressure pump can supplement air to the interior of the ampoule A through the ventilation channel 22, the pressure of the ampoule A is kept stable, and the residual liquid in the ampoule A can be ensured to flow out smoothly.

If the viscosity of the liquid stored in ampoule a is less than 3000cp, the vent passage 22 is directly connected to the atmosphere, without the need for a pressure pump. If the viscosity of the liquid stored in the ampoule A is higher than 3000cp, the vent passage 22 is communicated with the pressure pump, the pressure in the ampoule A is enhanced by the pressure pump, and the liquidity of the liquid in the liquid inlet passage 21 is increased.

In the embodiment, the spraying assembly atomizes the cosmetics or the medicines in a gas-liquid mixing mode. Of course in other embodiments, the cosmetic or pharmaceutical product may also be aerosolized ultrasonically as in the prior art.

Specifically, the spraying assembly comprises a valve core B2, a valve seat B1, an atomizing air pump B3 and a starting switch B4.
