Liquid such as release agent is filled into the liquid inlet interface 128, the liquid enters the liquid inlet channel 127, the pressure of the liquid is larger than the elastic force of the control spring 117, the control ball 119 moves towards the control piston 118 in the control piston cavity 116, and the liquid enters the quantitative channel 126 after the control ball 119 moves. The pressure of the liquid in the quantitative passage 126 is less than the elastic force of the quantitative spring 123, i.e. the quantitative blocking ball 125 still blocks the quantitative passage 126 under the elastic force of the quantitative spring 123. Then, the pulse valve is used for controlling the control gas to be filled into the control gas channel 111 in a pulse mode through the control gas butt joint 115, the control gas pressure filled in each pulse is larger than the pressure of the atomized gas, so that the control gas enters the control piston cavity 116 and pushes the control piston 118 to move towards the control ball plug 119 in the control piston cavity 116, and finally the control ball plug 119 is driven to move towards the liquid inlet channel 127 and plug the liquid inlet channel 127, and therefore the liquid with the determined volume can be formed in the quantitative channel 126 and the control piston cavity 116 between the control ball plug 119 and the control piston 118 in the pulse process of each control gas. Then the piston 118 is controlled to move continuously to compress a fixed amount of liquid, so that the pressure of the fixed amount of liquid is increased, after the pressure of the fixed amount of liquid is greater than the elastic force of the fixed amount of spring 123, the fixed amount of ball 125 moves towards the fixed amount of piston 124, the last fixed amount of liquid enters the second liquid inlet section 121, the middle liquid main channel 401 and the upper liquid main channel 301, and finally the liquid is ejected from the liquid nozzle 302 and flows into the spray groove 204. The atomized gas injected into the spout 204 from the atomizing gas port 208 and the annular atomizing port 270 is mixed with the liquid in the spout 204, thereby achieving atomized spraying of the liquid such as the mold release agent. Because the pressure and the volume of the liquid entering the quantitative channel 126 in each pulse process of the control gas are fixed, the pressure of the atomized gas connected with the interface 114 only needs to be stable, and the nozzle can spray quantitative atomized liquid in each pulse injection, so that the uniformity and the stability of the spraying are ensured, and the spraying amount is accurate and controllable.
