The nozzle in this embodiment is adapted to the dual-bag aerosol valve, and the specific structure of the dual-bag aerosol valve is applied for another application, which does not belong to the innovation point of this application and is not described herein again. The working principle of the dual-bag aerosol valve is briefly described here: can be used for containing hair dye, and is sealed after being filled with compressed air not more than 0.1 MPa through professional filling equipment, so that the content in the bag always has proper pressure. The hair dye is mixed with butane in a proper ratio under a pressure-maintaining condition before filling. Hair dyes are generally divided into two parts, AB, and must be stored separately before use. The double-bag design comprises a first bag and a second bag, a first material guiding pipe and a second material guiding pipe are respectively placed in the first bag and the second bag, and the contents in the first bag and the second bag are respectively communicated with an outer channel 22 and an inner channel 21 of the valve rod 02 through the first material guiding pipe and the second material guiding pipe under the pressure action of compressed air and butane.

Referring to the illustrations of fig. 4 to 5, the bottom of the nozzle 01 of the present embodiment is directly connected to the valve stem 02 of the dual bag aerosol valve, a vertical material passage is provided on the valve stem 02, the material passage includes an inner passage 21 and an outer passage 22, the inner passage 21 of the valve stem 02 is communicated with the first through hole 4 of the nozzle 01, and the outer passage 22 of the valve stem 02 is communicated with the second through hole 5 of the nozzle 01. The outer wall of the valve stem 02 is provided with an inner liquid inlet hole 23 and an outer liquid inlet hole (not shown) which are respectively communicated with the inner passage 21 and the outer passage 22. Wherein, the inner liquid inlet hole 23 is arranged at the lower part of the valve rod 02, and the outer liquid inlet hole is arranged at the upper part of the valve rod 02. When the nozzle 01 is pressed, the nozzle 01 applies a vertical downward pressure to the valve rod 02, so that the inner liquid inlet hole 23 and the outer liquid inlet hole which are originally blocked by the sealing ring are exposed, and the content of the first bag enters the outer channel 22 from the first material guiding pipe through the outer liquid inlet hole under the pressure action of compressed air and butane; the contents of the second bladder are forced by the pressure of the compressed air and butane from the second feed tube through the inner feed opening 23 into the inner passage 21. Therefore, the two materials in the two pockets enter the liquid ejecting chamber 3 through the inner passage 21 and the first through hole 4, and the outer passage 22 and the second through hole 5, respectively, and are ejected in the liquid ejecting chamber 3 in a mixed manner under the action of pressure.
