In addition, the term "or" used in this article may include any one or more combinations of the associated listed items depending on the actual situation.

[0029] See also Figures 1 to 16 As shown, the present invention provides a nebulizer assembly S, and the nebulizer assembly S includes a nebulizer host N and an airflow guide M (or a mouthpiece or a nozzle). The nebulizer host N includes a host body N1, a medicine placement module N2 (or a medicine capsule or a medicine cup) arranged on the host body N1, and an atomization module N3 arranged inside the medicine placement module N2, and the airflow guide M includes a gas guide part 1 and a structural matching part 2. Further, the gas guide part 1 includes a first hollow tube body 11, a second hollow tube body 12, and a gas guide structure 13 connected between the first hollow tube body 11 and the second hollow tube body 12, and the structural matching part 2 is connected to the first hollow tube body 11 of the gas guide part 1. In addition, the gas guide structure 13 has a plurality of rear-end gas main introduction channels 1300 surrounding the first hollow tube body 11, and each rear-end gas main introduction channel 1300 has a rear-end gas main introduction opening 13000 perpendicular or inclined to the structural matching part 2.

[0030] Thereby, when the user turns on the nebulizer host N so that the atomization module N3 of the nebulizer host N produces an aerosol fluid F, the external air A can be introduced into a rear gas guide channel 1000 of the gas guide part 1 through multiple rear-end gas main introduction channels 1300, so that multiple liquid medicine particles of the aerosol fluid F can be pushed forward by "the external air A introduced by the multiple rear-end gas main introduction channels 1300".

[0031] [First embodiment]

[0032] See also Figures 1 to 4As shown, the first embodiment of the present invention provides an airflow guide M and an atomizer assembly S using the airflow guide M.

[0033] First, cooperate Figure 1 and Figure 2 As shown, the nebulizer assembly S includes a nebulizer host N and an airflow guide M installed on the nebulizer host N. The nebulizer host N includes a host body N1, a medicine placement module N2 arranged on the host body N1, and an atomization module N3 arranged inside the medicine placement module N2, and the airflow guide M includes a gas guide part 1 and a structural matching part 2. For example, the medicine placement module N2 can be detachably or fixedly arranged on the host body N1 for accommodating a predetermined liquid medicine, and the atomization module N3 can convert the predetermined liquid medicine contained in the medicine placement module N2 into an aerosol fluid F through the nozzle plate module. In addition, a joint portion is provided on the outer surface of the structural matching part 2, and the airflow guide M can be installed on the nebulizer host N through the mutual cooperation of the joint portion and a joint portion of the nebulizer host N. For example, a thread structure 20 is provided on the outer surface of the structure matching portion 2, and the airflow guide M can be installed on the atomizer host N through the mutual cooperation of the thread structure 20 and a thread structure N100 of the atomizer host N, so the airflow guide M can be replaceably installed on the atomizer host N according to different usage requirements. However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0034] Furthermore, cooperation Figure 3 and Figure 4 As shown, the gas guide portion 1 includes a first hollow tube body 11, a second hollow tube body 12, and a gas guide structure 13 connected between the first hollow tube body 11 and the second hollow tube body 12. In addition, the structure matching portion 2 is connected to the first hollow tube body 11 of the gas guide portion 1 to cooperate with the thread structure N100 of the atomizer host N (such as Figure 1). More specifically, the gas guiding structure 13 includes a plurality of front main flow guiding walls 131 and a rear main flow guiding wall 132. The plurality of front main flow guiding walls 131 are sequentially connected and disposed around the first hollow tube 11, and the rear main flow guiding wall 132 is connected around the plurality of front main flow guiding walls 131 and the second hollow tube 12. In other words, the gas guiding structure 13 includes a third hollow tube (not numbered) extending from the first hollow tube 11 to the second hollow tube 12, and the third hollow tube includes a plurality of supporting columns (not numbered) connected around the first hollow tube 11, so that a plurality of through-channels can be generated between the third hollow tube and the first hollow tube 11. In addition, a radial distance of the rear main flow guiding wall 132 gradually decreases from the first hollow tube 11 toward the second hollow tube 12 (that is, the rear main flow guiding wall 132 presents a tapered tubular structure). For example, the surface contour of an outer peripheral surface formed by the plurality of front main guide walls 131 connected in sequence can be circular or in any shape, and a mouthpiece opening of the second hollow tube 12 can be circular, elliptical or in any shape. However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0035] It is worth noting that with Figure 3 and Figure 4 As shown, the gas guide structure 13 has a plurality of rear gas main introduction channels 1300 (i.e., main rear air intake channels) surrounding the first hollow tube body 11, and each rear gas main introduction channel 1300 has a rear gas main introduction opening 13000 (i.e., main rear air intake port) perpendicular or inclined to the structure matching portion 2. In addition, when the airflow guide M is installed on the atomizer host N through the mutual cooperation of the threaded structure 20 and the threaded structure N100 of the atomizer host N (as shown in FIG. Figure 1 As shown in FIG. 1 ), the rear end gas main introduction opening 13000 of each rear end gas main introduction channel 1300 will face the atomizer host N (as shown in FIG. 1 ). Figure 2As shown), the rear-end gas main introduction opening 13000 belongs to the rear-end air inlet rather than the side air inlet for the atomizer assembly S. Furthermore, each rear-end gas main introduction channel 1300 is formed between the corresponding front-end main flow guide wall 131 and the first hollow tube body 11 (or, each rear-end gas main introduction channel 1300 is formed between two adjacent support columns), and the rear-end gas main introduction opening 13000 of each rear-end gas main introduction channel 1300 can be perpendicular or inclined to the first hollow tube body 11. For example, the angle of the rear-end gas main introduction opening 13000 of each rear-end gas main introduction channel 1300 relative to the first hollow tube body 11 (for example, the outer surface of the first hollow tube body 11) or the structural matching part 2 (for example, the outer surface of the structural matching part 2) can be between 80 degrees and 100 degrees (for example, including any positive integer between 80 degrees and 100 degrees). However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0036] In addition, with Figures 2 to 4 As shown, the interior of the structural matching part 2 has a front gas guide channel 2000, and the front gas guide channel 2000 of the structural matching part 2 is connected to the atomization module N3 of the atomizer host N. In addition, the interior of the gas guide part 1 has a rear gas guide channel 1000, and the rear gas guide channel 1000 of the gas guide part 1 is connected to the front gas guide channel 2000 of the structural matching part 2. Furthermore, a plurality of rear-end gas main introduction channels 1300 are connected to the rear-end gas guide channel 1000 of the gas guide part 1, so that an external air A (or ambient air) outside the airflow guide member M can be introduced into the rear-end gas guide channel 1000 of the gas guide part 1 through the plurality of rear-end gas main introduction channels 1300 (such as Figure 2 shown).

[0037] By this, Figure 2As shown, when an aerosol fluid F generated by the atomization module N3 of the atomizer host N is transmitted to the rear gas guide channel 1000 of the gas guide part 1 (that is, when the user inhales the airflow guide member M), the external air A can be introduced into the rear gas guide channel 1000 of the gas guide part 1 through multiple rear-end gas main introduction channels 1300, so that multiple liquid medicine particles in the aerosol fluid F can be pushed forward by the external air A introduced by the multiple rear-end gas main introduction channels 1300. Therefore, the multiple drug liquid particles of the aerosol fluid F generated by the atomization module N3 can pass through the "external air A introduced by the multiple rear-end gas main introduction channels 1300" to increase the forward flow speed of the aerosol fluid F and reduce the gas flow collision of the aerosol fluid F, thereby reducing the chance of excessive collisions between the multiple drug liquid particles of the aerosol fluid F and agglomeration into larger droplets. Therefore, the atomizer assembly S of the present invention using the airflow guide M can effectively reduce the residual drug amount (that is, reduce the number of multiple drug liquid particles of the aerosol fluid F that agglomerate to form larger droplets and fall inside the airflow guide M) and increase the atomized particle ejection rate (that is, increase the ratio of multiple drug liquid particles of the aerosol fluid F ejected from the airflow guide M).
