There are many ways to generate atomized particles by external power. Air pressure is one of them. There is usually a tiny space in the atomized medicine cup containing the liquid, which induces capillary phenomenon and transfers the liquid in the medicine cup upwards to the high pressure gas. The jet hole uses external high-pressure gas to hit the liquid to be atomized to produce tiny atomized particles for the patient to inhale.

However, as the atomization time increases, the liquid in the medicine cup becomes less and less, and the liquid level becomes lower and lower. Eventually, too little residual liquid will cause the capillary phenomenon to fail, and the ability to transfer the liquid will be lost. The air will replace the entry and cause interruption.

Based on the above, the atomization device, atomization medicine cup, and atomization airflow guide device of the present invention use a gap at the bottom of the liquid guide, and the adhesion force of the liquid will fill the gap first, and then the cohesion of the liquid can achieve The purpose of agglomerating the liquid is to prevent the scarce residual liquid from spreading around the medicine cup, leading to the failure of the capillary phenomenon of the transferred liquid. The original liquid transfer path is replaced by air, and the atomization process is interrupted, which not only improves the atomization conversion rate of the liquid, but also In addition, the residual liquid rate of the medicine cup is reduced, and the residual liquid consumption is saved. At the same time, the atomized airflow passes through the accumulation and screening in the enlarged space, which reduces the passing rate of the atomized large particles and improves the uniformity of the quality of the atomized particles.

In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

In the above-mentioned conventional knowledge, when too little residual liquid is stored in the medicine cup, a small amount of liquid is easily dispersed throughout the medicine cup, which will cause the capillary phenomenon to fail, and the liquid cannot be continuously transferred to the high-pressure gas jet hole, causing the atomization to stop and the residual liquid cannot be fully utilized. In addition, after the liquid is atomized, there is a problem of different sizes of atomized particles. If the user inhales the large atomized particles, the medicine may not reach the correct position that needs to be treated. It is no different from waste. How to produce The homogenized atomization airflow of small particles is the important key.

In contrast, the embodiment of the present invention opens a gap at the bottom end of the liquid guide that is in contact with the liquid. The gap changes the original smooth shape of the bottom end, increases the contact area with the liquid, and fills the gap direction preferentially through the liquid adhesion force. At the same time, the cohesive force of the liquid will agglomerate other residual liquids to achieve the purpose of continuous transmission of the concentrated liquid to the jet hole. In addition, after the atomized particles are generated from the medicine cup, they pass through the enlarged part of the tubular shell to provide a space for the accumulation and screening of the atomized airflow, which is too large. The overweight atomized particles are then screened and dropped again, and only light enough atomized particles can pass through, outputting homogeneous atomized small particles.

Figures A to D are three-dimensional schematic diagrams of a preferred embodiment of a liquid guide of the atomization device according to the present invention from different perspectives. Please refer to FIGS. 4 to 6 D together. In this embodiment, the liquid guide 22 has a cover 220 in the center, which is complementary in shape to the protrusion 211 for assembling with the protrusion 211, more specifically In other words, assuming that the shape of the protrusion 211 is cylindrical, the cover 220 is bell-shaped with a recessed space therein, and the diameter of the cover 220 is larger than the diameter of the protrusion 211 to accommodate the protrusion The portion 211, in other words, the protruding portion 211 and the cover 220 are a convex and a concave complementary structure. An annular gap 221 is formed between the protrusion 211 and the cover 220 for conducting the liquid 2. More specifically, the bottom end of the cover 220 will be in contact with the liquid 2 in the storage space 210, and the diameter of the cover 220 and the diameter of the protrusion 211 are only slightly different, so that it surrounds the protrusion 211 The surrounding liquid 2 can fill the space of the annular gap 221 from bottom to top by capillary phenomenon.

The bottom end of the cover 220 is provided with at least one notch 222 for guiding the liquid 2 to the annular gap 221. More specifically, the contact surface of the bottom end of the conventional cover with the liquid is a smooth linear shape. When the liquid gradually decreases, the smooth linear shape is not conducive to attracting the residual liquid, and the residual liquid cannot be transferred to the annular gap. This causes the problem of capillary failure. However, when the notch 222 is provided at the bottom end of the cover 220, the originally smooth linear contact surface will be broken. The liquid will easily gather at the notch due to the adhesion force, and then the cohesion of the liquid will be generated. Agglomeration, and then solve the problem that the residual liquid is not easy to be transferred. Preferably, the notch 222 is a plurality of notches, and more preferably, the plurality of notches 222 are arranged symmetrically. When the residual liquid is too little, the liquid 2 may be scattered in a certain part of the storage space 210, or because the bottom of the storage space 210 of the liquid storage member 21 is not a horizontal plane, and the liquid tends to collect in a certain corner , The plurality of gaps 222 will increase the chance of contact with the liquid 2 in different directions, and increase the probability of the liquid 2 being attracted to the gap 222 to gather. Among them, the symmetrical distribution of the plurality of gaps 222 will increase the probability of each orientation evenly, More preferably, the bottom end of the cover body 220 is a liquid surface contact end perpendicular to the outer side wall 2200 and the inner side wall, and all of the notches 222 can be configured.

The seventh figures A to C are three-dimensional schematic diagrams of different embodiments of the liquid guiding member partially enlarged with a notch according to the present invention. Please refer to FIGS. 4 to 7 C together. Preferably, the notch 222 is a notch connecting the inner and outer side walls of the cover 220. In other words, the annular gap 221 exists in the cover 220 Between the side wall 2201 and the outer side wall 2200 of the protruding portion 211, when the gap 222 provides a communication channel between the inner side wall 2201 and the outer side wall 2200 of the cover 220, the liquid 2 will be transmitted to the ring shape. Probability of gap 221. Preferably, the inner side wall 2201 or the outer side wall 2200 at the bottom end of the cover 220 has an arc modification 2203 to increase the contact area with the liquid. More specifically, the inner side wall or outer side wall of the conventional cover is at right angles to the bottom end structure, and the contact system with the liquid is two mutually perpendicular planes. However, when the residual liquid level is too low, it can only contact the bottom end structure. The horizontal plane cannot touch the vertical surface of the inner side wall or the outer side wall, resulting in the failure of the function of relying on capillary action to achieve liquid transfer. However, when the inner side wall 2201 or the outer side wall 2200 at the bottom end of the cover 220 has the arc modification 2203 At the same time, a circular arc is used to provide the connection of two mutually perpendicular planes, which eliminates the line of intersection that would otherwise cause separation, increases the contact area with the liquid 2, and promotes the liquid 2 to be transported to the annular gap through the cohesive force of the liquid 2 The probability of 221. Preferably, the shape of the notch 222 is V-shaped 222a or U-shaped 222b, 222c, but the present invention is not limited to this. Preferably, the notch 222 is provided at the bottom end of the liquid guide groove 223, because the liquid guide groove 223 is provided on the inner side wall 2201 of the cover 220 to have more space to transmit the liquid 2, and the liquid guide groove 223 The other end of the liquid guiding groove 223 is a liquid outlet 224.

Assuming that from a top view, the hollow portion 2202 is circular, and the protrusion 2204 is semicircular. The liquid outlet 224 is located at the center of the circle, but the present invention is not limited to this. The extending direction of the liquid outlet 224 and the extending direction of the jet hole 212 are perpendicular to each other. More specifically, when the liquid 2 flows from the liquid outlet 224 When it overflows, it will be hit by the high-pressure gas jetted vertically upward from the jet hole 212 below, so that the liquid 2 will be hit by the high-pressure gas to form atomized particles.

When the liquid 2 is hit by high-pressure gas, splashing may occur, part of the liquid 2 forms atomized particles, part of the liquid 2 falls back to the atomized medicine cup 20, and the splashed liquid 2 may accumulate on the protrusion 2204 When too much water accumulates on the top of the stud 2204, it may fall in the direction of the jet hole 212, which will damage the stability of the continuous water supply from the liquid outlet 224, and suddenly drop a large amount of the liquid 2 The impact of high-pressure gas will affect the size of the atomized particles generated and reduce the atomization rate. Therefore, preferably, the top of the protrusion 2204 has a rib 2205 extending from the top of the protrusion 2204 to the cover 220 The top of the stud 2204 is used to guide and remove the stagnant water remaining on the top of the protrusion 2204. When the water accumulates on the top of the stud 2204, it can slide down the rib 2205 to the top of the cover 220, so as to eliminate the water on the top of the stud 2204 and reduce the probability of the water supply balance being damaged. In another embodiment, the top of the protrusion 2204 has a groove 2206 that extends from the top of the protrusion 2204 to the top of the cover 220 for guiding and removing the stagnant water remaining on the top of the protrusion 2204. In other words, the groove 2206 and the rib 2205 have the same effect of removing accumulated water. Preferably, the rib 2205 or the groove 2206 can coexist on the protrusion at the same time. More specifically, the shape of the rib 2205 or the groove 2206 can be rectangular, arc-shaped, V-shaped, or U-shaped. , W-shape or any shape that can increase the liquid contact area. Preferably, there are a plurality of the ribs 2205 or the grooves 2206 to increase the efficiency of removing the accumulated water on the top of the protrusion 2204.

The eighth figure A to the eighth figure C are three-dimensional schematic diagrams of different viewing angles of the preferred embodiment of the atomizing airflow guide according to the present invention. Please refer to Figures 1 to 4 and Figure 8A to Figure C in combination. In this embodiment, the atomizing airflow guiding device 30 is suitable for the atomizing medicine cup 20. Preferably, the mist The gas flow guiding device 30 is an integrally formed structure, but the present invention is not limited to this. The atomizing airflow guiding device 30 includes an airflow inlet 31, a first tubular shell 32, a second tubular shell 33, and an airflow outlet 34.

Preferably, the air inlet 31 and the atomized medicine cup 20 are connected to form a tight fitting structure. More specifically, the shape of the connection between the air inlet 31 and the atomized medicine cup 20 is similar. For example, the air inlet 31 is circular, and the shape of the joint of the atomized medicine cup 20 is also circular, but the diameter is slightly larger than the diameter of the airflow inlet 31. When the airflow inlet 31 is put into the joint of the atomized medicine cup 20, The first end 321 of the first tubular shell 32 is squeezed to produce a slight deformation, and the connection with the atomized medicine cup 20 reaches a tightly fitted state, but the present invention is not limited to this.

The second end 322 of the first tubular shell 32 has an enlarged portion 323 to provide a storage space for screening atomized particles. Preferably, the enlarged portion 323 has an arc-shaped curved surface to provide a turning direction of the atomized airflow.

A tubular casing 32 is connected at different angles. Preferably, the angle 36 between the second tubular casing 33 and the first tubular casing 32 is less than 180 degrees. More specifically, the enlarged portion 323 is located at the first tubular casing. The junction of a tubular shell 32 and the second tubular shell 33 at the junction.

When the atomized particles from the atomized medicine cup 20 are not completely screened, there may be a problem of different sizes of atomized particles. When the atomized airflow enters the atomized airflow guide device 30, its passing path is the airflow inlet sequentially. 31. The first tubular housing 32, the second tubular housing 33, and the airflow outlet 34, the airflow outlet 34 is provided at the end of the second tubular housing 33, preferably, the second tubular housing 33 The direction of the airflow outlet 34 is to gradually expand the opening path. When the atomized airflow passes through the enlarged part 323, due to the turning of the direction, the larger atomized particles will not be able to turn and fall. Not only that, the enlarged part 323 provides more extra space at the turning point to increase the screening of atomized particles. After entering the space of the enlarged portion 323, the larger atomized particles are more likely to stay or fall, reducing the probability of the atomized large particles being discharged to the airflow outlet 34.
