Output channels 45 are provided on both sides of the upper bracket 40 along the thickness direction, and the aerosol in the atomization chamber is output to the flue gas output pipe 11 as shown by arrow R2 in FIG. 3 and FIG. 6 .

In order to cooperate with the liquid guiding of the atomizing assembly 30 , the sealing element 60 is provided with a first liquid guiding hole 62 for the liquid substrate to flow to the upper bracket 40 . The upper bracket 40 is also provided with a second liquid guide hole 42.

Further in the preferred implementation shown in FIGS. 8 and 9 , the upper bracket 40 is provided with a shielding portion 46 extending in the lateral direction, and the shielding portion defines the first cavity 43 . On the one hand, the projection of the shielding portion 46 along the longitudinal direction of the atomizer 100 covers the heating element 32, so that in use, it can shield the large droplets formed by frying oil during the heating process of the heating element 32, and on the other hand, it can also block the mist The condensate and the like in the chemical chamber are prevented from flowing directly to the flue gas output pipe 11 .

Further referring to the preferred embodiment shown in FIGS. 6 to 9 , the lower end of the flue gas output pipe 11 inserted into the upper bracket 40 is provided with at least one gap 111 , and the upper bracket 40 is provided with a rib 47 matching the gap 111 . Specifically in FIG. 8 , the rib 47 extends along the longitudinal direction of the atomizer 100 and has two parts with different widths, a first part 471 close to the flue gas output pipe 11 and a first part 471 away from the flue gas output pipe 11 . Two parts 472; wherein, the first part 471 has a smaller width than the second part 472, and the first part 471 is thinner than the second part 471 in form.

The notch 111 has a width of approximately 1.2 mm.

The state after assembly is shown in FIG. 9 , the first part 471 at least partially extends into the notch 111 at the lower end of the flue gas output pipe 11 ; and the second part 472 is located outside the notch 111 . After being assembled at the same time, the two side surfaces of the first part 471 are not in contact with the two side surfaces of the notch 111 , and a certain distance is maintained between the first part 471 and the two side surfaces of the notch 111 according to FIG. 9 . The spacing is further controlled to be less than 2 mm, thereby forming longitudinally extending capillary channels 80 . Further in use, when the aerosol condensate formed on the inner wall of the flue gas output pipe 11 falls or flows down to the lower end due to gravity, the capillary adsorption and guiding force of the capillary channel 80 will force the lower end of the flue gas output pipe 11 to flow. The condensate is guided downward into the support 40, thereby preventing the condensate from accumulating on the inner wall or the lower end of the flue gas output pipe 11, thereby alleviating or eliminating the problem of sucking the condensate.

Referring further to the preferred implementation shown in FIG. 8 , the lower end of the rib 47 is connected to the shielding portion 46 , so that the condensate droplets absorbed and conducted by the capillary channel 80 fall onto the shielding portion 46 . In the preferred implementation shown in FIGS. 8 and 9 , the shielding portion 46 is in the shape of an arc, and the condensate that subsequently flows on the shielding portion 46 is guided downward by the arc-shaped upper surface and flows into the atomization chamber, as shown in FIG. 9 . Indicated by the middle arrow R3.

In the preferred implementation shown in FIG. 8 , the extension length of the second portion 472 is greater than that of the first portion 471 . In an implementation, the length of the second portion 472 is approximately 3 mm and the length of the first portion 471 is approximately 2 mm.

Further in other optional implementations, the protruding rib 47 further includes a guide groove 473 defined by the second portion 472 and the wall of the upper bracket 40 . In FIG. 8 , the part where the second part 472 is combined with the upper bracket 40 has a guide groove 473 , and the guide groove 473 further helps to quickly guide the condensate transferred by the capillary channel 80 to the shield. On the part 46 , the condensate is prevented from being adsorbed and held in the capillary channel 80 between the first part 471 and the flue gas output pipe 11 .

In other variant implementations, the atomizing component 30 may also be other currently commonly used porous ceramic atomizing components; the porous ceramic may be, for example, the porous ceramic body with laterally penetrating liquid channels proposed by the applicant in Patent No. 201920645593.5, Or the usual cup-shaped ceramics with grooves on the upper surface. The assembly is also accommodated and held by the upper support 50 and transfers the liquid matrix to the porous ceramic body.

In other alternative or variant implementations, the rib 47 can be varied to other shapes and positions. For example, FIG. 10 shows a schematic structural diagram of yet another upper bracket 50a with protruding ribs 47a. The rib 47a of Fig. 10 has a larger size than the rib 47 of Fig. 8 . In shape, it also has a first part 471a and a second part 472a, while the second part 472a and the wall 400a of the upper bracket 40a are formed with a longitudinally extending guide groove 473a at the joint, so as to transmit the condensate downwards faster .

The first portion 471a is more centrally positioned than the first portion 471, and is also not in contact with the wall 400a of the upper bracket 40a, thereby forming a receiving space 4711a between them. After assembly, the notch 111 at the lower end of the flue gas output pipe 11 extends into the accommodating space 4711a, so that the space of the capillary channel 80 between the protruding rib 47a and the flue gas output pipe 11 can be further expanded, so as to accommodate more and containment of aerosol condensate is advantageous. Likewise, after assembly, a part of the first part 471a still extends into the gap 111 of the flue gas output pipe 11 and retains a certain distance, forming a capillary channel for absorbing and transferring the condensate at the lower end of the flue gas output pipe 11 .

Fig. 11 shows a schematic diagram of a flue gas output pipe 11a prepared in the main casing 10a according to another embodiment. In the implementation shown in FIG. 11, the cross-sectional shape of the flue gas output pipe 11a is a flat shape, preferably an oval shape; The thickness direction of 10a is the short axis B2, and the condensate in the flue gas output pipe 11a is more likely to gather at the end of the long axis B1 with a larger curvature. Furthermore, the end of the flue gas output pipe 11a is provided with a second notch 112a close to at least one side in the width direction of the main casing 10a. Through the second notch 112a, the end with the greater curvature of the long axis B1 is formed into a hollow space, In this way, the accumulation of the condensate here is eliminated, and the condensate is turned to be more concentrated to the position close to the first notch 111a, and then it is more convenient to guide it into the atomization chamber under the cooperation of the convex rib 47. Of course, further matching the oval or flat flue gas output pipe 11a, the above-mentioned first insertion hole 61 and second insertion hole 41 are also matched in a flat or oval shape. Likewise, in conjunction with the above implementation, the position of the protruding rib 47 needs to be adjusted to cooperate with the first notch 111a to form a capillary channel to guide the aerosol condensate.

In the preferred implementation shown in FIG. 11 , the first notch 111a has a width greater than that of the second notch 112a; the width of the first notch 111a in the implementation is about 2.4 mm, and the width of the second notch 112a is about 1 mm.

It should be noted that the description of the present application and the accompanying drawings provide preferred embodiments of the present application, but are not limited to the embodiments described in the present specification.
