The extension on one side is beneficial to increase the liquid lowering area of the lower liquid port 420 as much as possible. It can be understood that, in other embodiments, the two extended lower liquid ports 422 may also be arranged asymmetrically, for example, the liquid area lowered by one extended lower liquid port 422 may be larger than that of the other extended lower liquid port 422 . In some other embodiments, the main lower liquid port 421 may also be provided with extended lower liquid ports 422 extending from only one or more sides.

In this embodiment, there are two magnetic components 33 located on two sides of the base 30 .

Fig. 9 shows the heating seat 40 in an alternative solution of the present invention. The main difference between it and the above-mentioned embodiment is that the lower liquid port 420 in this embodiment also includes a connected lower liquid port 423, which connects the lower liquid port 423 to The two expanded lower liquid ports 422 are connected to each other, and can further increase the liquid area of the lower liquid port 420 .

In this embodiment, the lower liquid port 420 is annular, and a boss 426 can protrude upward from the lower liquid port 420 , and the vent hole 425 can extend downward from the upper surface of the boss 426 . One side of the boss 426 can be integrally combined with the edge of the main lower liquid opening 421 . There is a certain distance between the other side of the boss 426 and the edge of the lower liquid port 423 for the liquid to flow through.

In addition, the bottom surface of the chamber connected to the lower liquid port 423 can also be inclined, and the two sides of its length can be inclined towards the two expanded lower liquid ports 422, so that the liquid matrix in the connected lower liquid port 423 can flow to the expanded lower port under the action of gravity. The liquid port 422 flows to the main liquid port 421 through the extended liquid port 422 .

10-11 show the atomizing main body 20 in the first alternative of the present invention. The main difference between it and the above-mentioned embodiment is that in this embodiment, the sealing sleeve 70 further includes a covering part 721, which is set In the liquid inlet 720 and divide the liquid inlet 720 into two sub-liquid inlets 7201 . The cover portion 721 is located above the lower liquid port 420 and can cover part of the lower liquid port 420 . By covering part of the lower liquid port 420, when the atomizer 100 is in the reverse pumping state (the output port 121 faces downward), the resistance of the liquid matrix in the lower liquid channel 45 to flow back is increased, so that the lower liquid channel 45 always maintains liquid The substrate can be supplied to the absorbing liquid 51 for atomization, so as to reduce the burnt smell caused by air bubbles pouring back into the absorbing liquid 51 .

Specifically, the cover portion 721 may be located in the middle of the liquid inlet 720 , that is, the cover portion 721 is located above the main lower liquid port 421 and covers at least part of the main lower liquid port 421 . The two width sides of the covering part 721 are integrally combined with the width side edges of the middle part of the liquid inlet 720 . The two sub-liquid inlets 7201 are respectively located on the left and right sides of the cover portion 721 and communicate with the two expanded lower liquid ports 422 respectively. In addition, the two sub-inlets 7201 are arranged symmetrically on the left and right and are not connected to each other. It can be understood that, in other embodiments, only one side edge of the cover portion 721 may be integrally combined with one side edge of the liquid inlet 720 .

In this embodiment, the width of the covering portion 721 is consistent with the width of the main lower liquid opening 421 , and the length of the covering portion 721 is shorter than the length of the main lower liquid opening 421 . The cover part 721 can extend downward for a certain length, so that the lower part of the cover part 721 can be embedded in the main lower liquid port 421 , and the two sides of the width of the cover part 721 can respectively contact the hole walls on both sides of the width of the main lower liquid port 421 . The covering part 721 makes the left and right sides of the lower liquid channel 45 form a U-shaped tube connector, and through the liquid pressure on the left and right sides of the connector, there is always a liquid matrix in the lower liquid channel 45 that can be supplied to the suction liquid 51 . In other embodiments, there may also be a gap between the two sides of the width of the covering portion 721 and the hole walls on both sides of the width of the main lower liquid port 421 .

Fig. 12 shows the sealing sleeve 70 in the second alternative of the present invention, the main difference between it and the first alternative is that the cover part 721 in this embodiment divides the liquid inlet 720 into two main liquid inlets 7202 And an auxiliary liquid inlet 7203. The two main liquid inlets 7202 communicate with the two expanded lower liquid ports 422 respectively, and one auxiliary liquid inlet 7203 communicates with the main lower liquid port 421 correspondingly. It can be understood that, in other embodiments, each expanded lower liquid port 422 can also communicate with more than one main liquid inlet 7202, and/or, the main lower liquid port 421 can also communicate with more than one auxiliary liquid inlet 7203 is connected.

The main function of the main liquid inlet 7202 is to ensure that the lower liquid area is large enough to be the main liquid supply path. The auxiliary liquid inlet 7203 can not only provide a certain amount of liquid supply, but also facilitate the atomization component 50 during the atomization process. Due to the negative pressure of the liquid storage chamber 110, the air bubbles entering from the micropores of the suction liquid 51 can be released in time. The ground is discharged from the lower liquid channel 45 to the liquid storage chamber 110. In this embodiment, both the two main liquid inlets 7202 and one auxiliary liquid inlet 7203 have a larger liquid area, and the two main liquid inlets 7202 are respectively located on two opposite sides of the liquid inlet 720, and the auxiliary liquid inlet The port 7203 is located in the middle of the liquid inlet 720 .

Fig. 13 shows the sealing sleeve 70 in the third alternative of the present invention, the main difference between it and the second alternative is that the covering part 721 in this embodiment divides the liquid inlet 720 into two main liquid inlets 7202 And two auxiliary liquid inlets 7203. The two auxiliary liquid inlets 7203 are located above the main lower liquid port 421 and communicate with the main lower liquid port 421 , so that each auxiliary liquid inlet 7203 has a smaller lower liquid area. Generally speaking, the smaller the liquid area of the auxiliary liquid inlet 7203 is, the greater the surface tension of the liquid matrix is, and the liquid matrix in the lower liquid channel 45 is less likely to flow out from the lower liquid channel 45 in the back pumping state.

It can be understood that the above technical features can be used in any combination without limitation.

Above embodiment has only expressed the specific implementation manner of the present invention, and its description is comparatively specific and detailed, but can not therefore be interpreted as the limitation of patent scope of the present invention; It should be pointed out that, for those of ordinary skill in the art, in Under the premise of not departing from the concept of the present invention, the above-mentioned technical features can be freely combined, and some deformations and improvements can also be made, which all belong to the protection scope of the present invention; therefore, all equivalent transformations made with the scope of the claims of the present invention All modifications and modifications should fall within the scope of the claims of the present invention.
