Specifically, the front part (134) extends from the middle part (135) to the nozzle front end (131) in a linear expansion manner; and the rear part (136) extends from the nozzle rear end (132) to the middle part in a linear contraction manner. part (135); the front part (134) extends from the middle part (135) to the front end of the nozzle (131) in a linear expansion manner; and the rear part (136) extends from the rear end of the nozzle (132) in a curved reduction manner to The middle part (135); the front part (134) extends from the middle part (135) in a curved expansion manner to the front end of the nozzle (131); and the rear part (136) extends from the nozzle rear end (132) in a straight line reduction manner. to the middle part (135); or the front part (134) extends from the middle part (135) in a curved expansion to the front end of the nozzle (131); and the rear part (136) decreases in a curve from the rear end of the nozzle (132) The way extends to the middle part (135). In a preferred embodiment, in order to improve the atomization effect of the essence, the middle part (135) is a parallel short straight tube, but it is not limited to this.

Even better, as shown in Figures 6A and 6B, it is a series of average particle size distribution diagrams to show the difference in the atomization effect produced when spraying the essence under different designs of the nozzle (13). , among which: the difference between the nozzle (13) used in Figure 6A and the nozzle (13) used in Figure 6B is only whether there is an air inlet (15) formed, and other conditions are the same. As shown in Figure 6A, the nozzle (13) used therein is not provided with an air-enhancing port (15). Specifically, when the essence leaves the inside of the nozzle (13), the particle diameter of the essence is almost maintained at Maximum value (100μm), so it is understandable that its atomization effect is not good. Because the essence particles are too large and too concentrated, they can easily cause damage to human skin; The scope of action is too concentrated, the coating range is uneven, and it is not easy for human skin to absorb. In addition, as shown in Figure 6B, it is designed using the nozzle (13) provided by the present invention, and an air inlet (15) is formed on the outer edge of the nozzle (13). It can be found that when the nozzle of the present invention is used (13), the part with a diameter of 10 μm that leaves the inside of the nozzle increases significantly, indicating that the design of the nozzle (13) of the present invention can significantly improve the atomization effect and reduce the size of the essence particles. Specifically, using the nozzle of the present invention (13) The atomized essence particles will not damage the skin; they can be gently spread on the surface of the skin, allowing the skin to absorb evenly; and can increase the body's absorption efficiency.

Even better, as shown in Table 1 below, where D[4,3] refers to the volume weighted average particle size; DV(10) refers to: 10% of the total content of particles is below this particle size; DV(50) ) means: 50% of the total content of particles is below this particle size, and also indicates the median value of the particle; DV (90) means: 90% of the total content of particles is below this particle size; SPAN It refers to the width of the distribution. The larger the value, the more dispersed the particle distribution. Among them, it can be understood that when the nozzle (13) without the air-enhancing port (15) is used to spray the essence, the average particle size of the essence is large and densely distributed. It can be seen from its DV (50): The median particle size of the particles reaches 90.82 μm, which is much larger than the size of the particles sprayed by the nozzle (13) with the air-increasing port (15). Therefore, it can be clearly understood that: compared with Compared with previous technologies, it has an excellent atomization effect.

Compared with the prior art, the effect of the present invention is that the essence sprayed by the nozzle (13) has a good atomization effect and can be evenly applied, making it easier for human skin, tissue, or cells to absorb; The feeding mechanism (12) can effectively control the transportation of the essence and properly preserve the essence, so that the essence can maintain its activity and not easily deteriorate; the solenoid valve (1) can minimize friction and speed up the valve shaft. (5) The moving speed can achieve the effect of rapid action and minimize the degree of gas loss; the gas guide path is smooth, and the pressure loss can be minimized during the gas guide process; the structure is simple and easy to assemble It is convenient and can meet the needs of mass production or customized production; it is also easy to clean and can be reused without worrying about bacterial infection; in addition, since the pressure around the front end of the nozzle (131) is close to one atmosphere, it will not cause damage to skin tissue or cells. or dangerous, can be used with peace of mind.
