In some embodiments, the bottom wall of the bottom cap has a cylindrical liquid injecting portion 127 protruding toward the inner wall of the liquid storage chamber 125, the liquid injecting portion 127 has a liquid injecting hole 1272 penetrating along the thickness direction of the bottom wall of the bottom cap, two ends of the liquid injecting hole 1272 can be respectively communicated with the external environment and the liquid storage chamber 125, and the inner diameter of the liquid injecting hole 1272 matches with the outer diameter of the liquid injecting tube 230 of the liquid injecting device 200. In this way, the injection tube 230 of the injection device 200 can be inserted into the injection hole 1272 to inject the atomized liquid into the liquid storage chamber 125 through the injection hole 1272.

In the stock solution chamber 125 is all located to drain 140 and sealing member 160, drain 140 forms the inlet channel who is used for communicateing external environment and stock solution chamber 125 with stock solution casing 120 jointly, outside drain 140 was located to the sealing member 160 cover, but sealing member 160 can produce the deformation of resumeing in order to open or seal inlet channel under the pressure effect of the atomized liquid in the inlet channel.

Thus, the liquid injection tube 230 of the liquid supply structure can be inserted into the liquid inlet passage to inject the atomized liquid into the liquid storage chamber 125. During liquid injection, the sealing member 160 deforms under the pressure of the atomized liquid in the liquid inlet channel to open the liquid inlet channel, and the atomized liquid flows into the liquid storage cavity 125 from the liquid inlet channel. After the liquid injection is completed, the pressure of the atomized liquid applied to the sealing member 160 disappears, and the sealing member 160 recovers the original shape to close the liquid inlet channel, so that the atomized liquid in the liquid storage cavity 125 cannot reversely flow out through the liquid inlet channel. It can be seen from this that, sealing member 160 can open or seal the inlet channel automatically under the pressure effect of atomized liquid, consequently compare in the operation that needs the manual suction nozzle of unscrewing of user or sealing plug among the prior art, is showing the convenience degree that has improved the notes liquid and is difficult to cause the weeping, and the unable direct contact atomized liquid of operator has higher security simultaneously.

Referring to fig. 4 and 5, in some embodiments, the liquid guiding seat is a hardware formed by a metal material, and has a high structural strength. The liquid guide 140 has a substantially circular truncated cone-shaped configuration, and the outer diameter of the liquid guide 140 increases monotonously in the liquid injection direction of the liquid injection hole 1272. Specifically, drain 140 includes drain diapire, drain roof and drain lateral wall, and drain diapire and drain roof interval and coaxial setting, and drain diapire and drain roof all are circular and the diameter of drain diapire is less than the diameter of drain roof, and the drain lateral wall is connected between drain diapire and drain lateral wall and encircles the edge of drain diapire and drain lateral wall along circumference.

Further, the liquid guiding member 140 is provided with a mounting hole 141 and at least one liquid outlet hole 143. Specifically, one end of the mounting hole 141 communicates with the outer surface of the drain bottom wall, the other end of the mounting hole 141 extends in the direction of the drain top wall along the extending direction of the central axis of the drain 140 (i.e., the filling direction of the filling hole 1272), and the inner diameter and depth of the mounting hole 141 match the outer diameter and height of the filling portion 127 of the liquid storage case 120. One end of the liquid outlet hole 143 is communicated with one end of the mounting hole 141 away from the liquid guiding bottom wall, and the other end of the liquid outlet hole 143 extends to the outer surface of the liquid guiding side wall along the direction intersecting the liquid injecting direction of the liquid injecting hole 1272. Thus, the liquid guiding member 140 can be sleeved outside the liquid injecting portion 127 through the mounting hole 141, the liquid guiding bottom wall abuts against the bottom cover bottom wall, and the liquid injecting hole 1272 and the liquid outlet hole 143 are communicated with each other to form a liquid inlet channel together.

So, a plurality of liquid holes 143 are radial interval setting, and a plurality of liquid holes 143 can flow out the atomized liquid simultaneously to liquid speed has effectively been improved. Moreover, when part of the liquid outlet holes 143 are blocked, the rest of the liquid outlet holes 143 can still normally discharge liquid. It can be understood that the number of the liquid outlet holes 143 is not limited, and different numbers can be set according to the requirement.

The sealing member 160 is a hollow cylindrical structure with two open ends, the shape of the sealing member 160 is matched with the shape of the liquid guiding sidewall of the liquid guiding member 140, and the inner diameter of the sealing member 160 is monotonically increased along the liquid injection direction of the liquid injection hole 1272, so that the sealing member can be sleeved outside the liquid guiding sidewall of the liquid guiding member 140. Also, the sealing member 160 is made of a material that is elastically deformable, and thus can be switched between an expanded state and a contracted state by an external force. Specifically, in one embodiment, the sealing member 160 is formed of a silicone material, which is elastically deformable and has high chemical stability and safety. It is understood that the material of the seal 160 is not limited and in other embodiments, may be other materials such as rubber.

Thus, after the liquid outlet channel is filled with the atomized liquid, the atomized liquid can apply an acting force to the sealing member 160 to make the sealing member 160 elastically deform and switch to the expanded state, so that the sealing member 160 is separated from the liquid guiding sidewall of the liquid guiding member 140, a gap is formed between the sealing member 160 and the liquid guiding member 140 to open the liquid inlet channel, and the atomized liquid in the liquid inlet channel flows into the liquid storage cavity 125.

And after annotating the liquid and accomplishing, sealing member 160 can resume to the shrink state fast, and under the pressure effect that the atomizing liquid in stock solution chamber 125 was exerted moreover, sealing member 160 more closely laminated drain lateral wall and the inseparabler closed inlet passage of drain 140 to have better leakproofness.

Preferably, the apex angle α of the liquid guide 140 is equal to or greater than 60 °, and the apex angle of the sealing member 160 is also equal to or greater than 60 °. It will be appreciated that the shape of the liquid guide 140 and the sealing member 160 and the angle of the cone apex angle α are not limited thereto, and may be provided in other different shapes as desired.

Referring to fig. 6, fig. 6 shows a cross-sectional view of another embodiment of the atomizer 100. In some embodiments, the inner wall of the end of the main housing 121 away from the bottom cover 123 protrudes to form a liquid injection portion 127, and the liquid guide member 140 is sleeved outside the liquid injection portion 127 and forms a liquid inlet channel communicating the external environment and the liquid storage cavity 125 together with the liquid injection portion 127.

After the injection is completed, the user pulls the injection tube 230 out of the injection hole 1272, and the sealing member 160 is restored to the original position and attached to the liquid guiding sidewall of the liquid guiding member 140. Moreover, since the atomized liquid in the liquid storage chamber 125 can apply pressure to the sealing member 160 to make the sealing member 160 tightly attached to the liquid guiding sidewall, the outlet of the liquid inlet channel is tightly sealed by the sealing member 160, and the atomized liquid in the liquid storage chamber 125 cannot flow back through the liquid inlet channel and leak out.

Above-mentioned atomizer 100, atomizing device and atomizing device subassembly, the user pegs graft priming device 200 in atomizer 100 and can conveniently pour into the atomized liquid into in stock solution chamber 125 through the inlet channel who opens automatically, and need not to adopt the mode of unscrewing the sealing plug of suction nozzle or stock solution chamber to open stock solution chamber 1250, has higher convenience in use.
