[0026] The lower side of the press head 2 is provided with a fixed sleeve 3.

[0027] The inside of the fixed sleeve 3 is provided with a sleeve b 10.

[0028] The lower end outer wall of the sleeve b 10 is fixedly connected with a sleeve a 7, the inside of the sleeve b 10 is provided with a reset spring 6, the lower end outer wall of the sleeve a 7 is provided with a suction pipe 8 for sucking in cosmetics, the inside of the fixed sleeve 3 is provided with a pressure relief pump 11 for reducing the pressure in the cosmetic bottle, a suction valve 9 is arranged between the sleeve a 7 and the sleeve b 10 for sucking in cosmetics through the suction pipe 8, a user presses down the press head 2, the pressing action makes the nozzle 1 start working and drives other components in the inside, after pressing, the reset spring 6 is compressed, the suction valve 9 moves downward and abuts against the upper end opening of the suction pipe 8, then the press head 2 is released, the reset spring 6 drives the suction valve 9 to move upward, a negative pressure environment is formed in the inside of the sleeve a 7, and the cosmetics are allowed to enter the inside of the sleeve a 7 through the suction pipe 8 and are atomized and sprayed outwards through the nozzle 1, in the use process, if the pressure in the cosmetic bottle is too high, the pressure relief pump 11 will automatically start to reduce the internal pressure, ensuring that the sprayer operates within a safe range, and the press head 2 is pressed again, so that the cosmetics can be sucked in again for spraying operation.

[0029] The other end of the nozzle 1 is provided with a return type pipe 17, the inside of the return type pipe 17 is provided with an adjusting plate 15 to control the gap through which the cosmetic can pass in the return type pipe 17, the upper side of the adjusting plate 15 is provided with a transmission rod 19 to drive the adjusting plate 15 to rotate under the action of external force, the inside of the upper end outer wall of the pressing head 2 is provided with a rotating plate 13 to drive the transmission rod 19 to rotate, the user can press the rotating plate 13 in advance to adjust, control the size of the space blocked by the adjusting plate 15 inside the return type pipe 17, so as to control the dosage of the subsequent cosmetic spraying, after the rotating plate 13 is adjusted, the pressing head 2 can be pressed to carry out the cosmetic spraying process, and according to the cosmetic flow space reserved by the adjusting plate 15, the dosage required by the user can be atomized.

[0030] As shown in Figure 3 , the upper end outer wall of the pressing head 2 is internally provided with a groove 14 to limit the position of the rotating plate 13, and the upper end circular outer wall of the return type pipe 17 is fixedly connected with a leakage prevention block 18.

[0031] When the rotating plate 13 rotates, it rotates in the inside of the groove 14, so as to ensure that the user pressing the pressing head 2 is substantially consistent with the original pressing feeling of the pressing head 2.
