In this embodiment, the liquid guide 22 has a cover body 220 in the center, which is complementary in shape to the protruding part 211, and is used for assembling with the protruding part 211. More specifically In other words, assuming that the protruding portion 211 is cylindrical in shape, the cover body 220 is bell-shaped with a recessed space therein, and the diameter of the cover body 220 is larger than that of the protruding portion 211 for accommodating the protruding portion 211. The portion 211 , in other words, the protruding portion 211 and the cover body 220 are a complementary structure of a convex and a concave. 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 is only slightly different from the diameter of the protrusion 211, so that The surrounding liquid 2 can fill up the space of the annular gap 221 from bottom to top by capillary phenomenon.

At least one notch 222 is defined at the bottom of the cover 220 for guiding the liquid 2 to the annular gap 221 . More specifically, the contact surface of the bottom of the known cover body to 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. However, when the gap 222 is provided at the bottom of the cover body 220, the original smooth linear contact surface will be broken, and the liquid will easily gather at the gap due to adhesion. Coagulation is then generated by the cohesive force of the liquid, thereby solving the problem that the residual liquid is not easily transported. Preferably, the notch 222 is a plurality of notches, 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 local position in the storage space 210, or because the bottom of the storage space 210 of the liquid storage part 21 is not a horizontal plane, the liquid is easy to gather in a certain corner , the plurality of notches 222 will increase the chances of contacting the liquid 2 in different directions, and increase the probability of the liquid 2 being attracted and gathered by the notches 222, wherein the symmetrical distribution of the plurality of notches 222 will increase the probability of each direction on average, More preferably, the bottom end of the cover body 220 is a liquid surface contact end perpendicular to the outer wall 2200 and the inner wall, which can all be configured by the notch 222 .

Please refer to the fourth figure to the seventh figure C together. Preferably, the notch 222 is a notch connecting the inner wall and the outer wall of the cover body 220. In other words, the annular gap 221 exists inside the cover body 220. Between the side wall 2201 and the outer side wall 2200 of the protrusion 211, when the gap 222 provides a communication channel between the inner side wall 2201 and the outer side wall 2200 of the cover body 220, it will increase the transmission of the liquid 2 to the annular Chances of gapping 221. Preferably, the inner sidewall 2201 or the outer sidewall 2200 of the bottom of the cover 220 has a circular arc modification 2203 for increasing the contact area with the liquid. More specifically, it is known that the inner wall or outer wall of the conventional cover is at a right angle to the bottom structure, and is two mutually perpendicular planes in contact with the liquid. However, when the residual liquid level is too low, only the bottom can be contacted. However, when the inner wall 2201 or the outer wall 2200 at the bottom of the cover 220 has the arc modification 2203 When using a circular arc to provide a connection between two mutually perpendicular planes, it eliminates the problem that would otherwise easily lead to separation. The intersecting lines increase the contact area with the liquid 2 , and through the cohesive force of the liquid 2 , the probability of the liquid 2 being transported to the annular gap 221 is increased. Preferably, the shape of the notch 222 is a V-shaped notch 222a or a U-shaped notch 222b, 222c, but the invention is not limited thereto. Preferably, the notch 222 is located at the bottom of the liquid guiding groove 223, because the liquid guiding groove 223 provides more space for the liquid 2 to be transported on the inner wall 2201 of the cover 220, and the liquid guiding groove 223 The other end of the liquid guide groove 223 is a liquid outlet 224 .

Preferably, the cover body 220 further includes a hollow portion 2202 and a stud 2204, the hollow portion 2202 is arranged at the top of the cover body 220 to expose the jet hole 212, preferably, the hollow portion 2202 The cross-sectional area is smaller than the cross-sectional area of the top of the cover body. More preferably, the cross-sectional area of the hollow portion 2202 is between the cross-sectional area of the top of the cover body 220 and the cross-sectional area of the jet hole 212, and the post 2204 is arranged on the cover. The top of the cover body 220 occupies part of the hollow portion 2202 , and the cross-sectional area of the stud 2204 is smaller than that of the top of the cover body 220 .

Assuming that the hollow part 2202 is circular in a top view, the protruding column 2204 is semicircular. , the liquid outlet 224 is located at the center of the circle, but the present invention is not limited thereto. The extending direction of the liquid outlet 224 is perpendicular to the extending direction of the jet hole 212. More specifically, when the liquid 2 exits from the liquid outlet 224 When overflowing, it will be impacted by the high-pressure gas sprayed vertically upward from the gas injection hole 212 below, so that the liquid 2 will form atomized particles after being impacted by the high-pressure gas.

When the liquid 2 is hit by the high-pressure gas, splashing may occur, part of the liquid 2 forms atomized particles, and part of the liquid 2 falls back to the atomizing medicine cup 20, and the splashed liquid 2 may accumulate on the stud 2204 When too much water accumulates on the top of the stud 2204, it may fall towards the direction of the jet hole 212, thereby destroying the stability of the continuous water supply originally from the liquid outlet 224, and suddenly falling a large amount of the liquid 2 is subject to The impact of high-pressure gas will affect the size of the atomized particles produced. Small and reduce the atomization rate, therefore, preferably, the top of the stud 2204 has a rib 2205, extending from the top of the stud 2204 to the top of the cover 220, to guide and eliminate the stagnation in the stud 2204 Waterlogging at the top. When water accumulates on the top of the pillar 2204 , it can slide down to the top of the cover 220 along the rib 2205 to remove the water on the top of the pillar 2204 and reduce the probability of water supply balance being disrupted. In another embodiment, the top of the stud 2204 has a groove 2206 extending from the top of the stud 2204 to the top of the cover 220 for guiding and removing the stagnant water on the top of the stud 2204 . In other words, the groove 2206 has the same effect as the convex rib 2205 to remove accumulated water. Preferably, the rib 2205 or the groove 2206 can coexist on the post, more specifically, the shape of the rib 2205 or the groove 2206 can be rectangular, arc, V-shaped, U-shaped , W-shape or any shape that increases the liquid contact area.
