The application provides an atomization device which can be used for atomizing liquid matrixes, and can be particularly applied to different fields, such as medical atomization, electronic atomization and the like. In one embodiment, the atomizing assembly is used in the field of electronic atomization, and in one embodiment, the atomizing assembly can also be used in medical equipment for treating upper and lower respiratory diseases to atomize medical liquid medicine and the like.

The atomizing device includes a housing assembly 10, a control assembly 20, and a pressure regulating valve 30.

The housing assembly 10 includes a gas storage chamber 11, a liquid storage chamber 12, an atomization chamber 13, and an atomization outlet 14. The gas storage chamber 11 is used for containing high-pressure gas with a pressure higher than atmospheric pressure, for example, as shown in fig. 2-3, the gas storage chamber 11 may directly contain the high-pressure gas, or as shown in fig. 4-5, the gas storage chamber 11 may indirectly contain the high-pressure gas, for example, a gas cylinder 40 is placed in the gas storage chamber 11, and the gas cylinder 40 is filled with the high-pressure gas. The high-pressure gas refers to a gas having a pressure higher than atmospheric pressure.

The reservoir 12 is adapted to hold a liquid medium, such as a liquid medicine, tobacco tar or other liquid medium that may be atomized. The first passage 15 capable of communicating the atomizing cavity 13 with the air storage cavity 11 is arranged in the housing assembly 10, so that when the first passage 15 is communicated, high-pressure air in the air storage cavity 11 or high-pressure air in the air bottle 40 can flow from the air storage cavity 11 to the atomizing outlet 14 to be discharged through the atomizing cavity 13 under the action of a first pressure difference, and the first pressure difference can be specifically the pressure difference between the air pressure of the air outlet 32 of the pressure regulating valve 30 and the atmospheric pressure.

When the first passage 15 is communicated, the pressure in the atomization cavity 13 is reduced when the gas flows to the atomization cavity 13 at a high speed, so that the pressure in the liquid storage cavity 12 is higher than the pressure in the atomization cavity 13, the liquid substrate can flow through the second passage 16 to be sprayed onto the cavity wall of the atomization cavity 13 under the action of a second pressure difference between the liquid storage cavity 12 and the atomization cavity 13, the liquid substrate is impacted on the cavity wall of the atomization cavity 13 at a high speed to be atomized into aerosol, namely the second pressure difference is specifically the difference between the pressure in the liquid storage cavity 12 and the pressure in the atomization cavity 13, the atomization cavity 13 is communicated with the atomization outlet 14, and the aerosol finally flows out of the atomization outlet 14 for a user.

The control assembly 20 is disposed on the first passage 15 between the atomizing chamber 13 and the gas storage chamber 11, and is used for controlling the on-off of the first passage 15. When the first passage 15 is closed, no negative pressure is generated at the atomizing cavity 13, and the liquid matrix is not ejected to form aerosol; when the first passage 15 is opened, a negative pressure is generated in the atomizing chamber 13, and the liquid matrix forms aerosol in the atomizing chamber 13. The control component 20 may be an electrically controlled first passage 15 or a purely mechanical structure to manually control the first passage 15, and in the present application, the control component 20 is to manually control the first passage 15 to realize that the atomizing device is independent of power supply for continuous voyage, so as to reduce defects of low service life, poor stability and the like of electronic components in the conventional atomizing device due to high temperature and high humidity, and the structure of the control component 20 is described in detail below.

The preset air pressure may be an air pressure value within a range in which the air pressure at the air outlet 32 fluctuates without causing the user to feel that the fluctuation in air pressure is large.

According to the atomization device, the pressure regulating valve 30 is arranged on the first passages 15 of the atomization cavity 13 and the air storage cavity 11, the pressure regulating valve 30 can regulate the air pressure at the air outlet 32 of the pressure regulating valve 30, so that the air pressure flowing out of the air outlet 32 of the pressure regulating valve 30 is stable, the initial air pressure is not excessive when a user uses the atomization device, the air pressure fluctuation is small in the use process, and the taste consistency is good.

In one embodiment, the cavity wall of the pressure regulating chamber 331 forms a linear sliding channel, that is, the cavity wall of the pressure regulating chamber 331 limits the radial direction of the core 35, so that the core 35 can slide linearly and reciprocally in the pressure regulating chamber 331 towards the direction approaching or separating from the air inlet 31. The sliding track of the core 35 is guided by the pressure regulating bin 331, so that the sliding of the core 35 can be more stable.
