Referring to fig. 9, the second frame 121 has a cavity therein, and a limiting wall, the atomizing chamber 1215 belongs to at least a portion of the cavity, and the limiting wall is used for limiting the length of the atomizing chamber 1215, so as to reduce the occupied space of the atomizing chamber 1215. Specifically, referring to fig. 9, a partial cavity is located inside the first support portion 1219a, which is the first cavity R3, and a partial cavity is located inside the second support portion 1219b, which is the second cavity R4, and the atomizing chamber 1215 is located between the first cavity R3 and the second cavity R4, and the limiting walls are two, which are the first limiting wall R21 and the second limiting wall R22, respectively, the first limiting wall R21 is disposed between the first cavity R3 and the atomizing chamber 1215 to separate the first cavity R3 from the atomizing chamber 1215, the second limiting wall R22 is disposed between the second cavity R4 and the atomizing chamber 1215 to separate the second cavity R4 from the atomizing chamber 1215, and the first limiting wall R21 and the second limiting wall R22 are located in the length direction, so that the length of the atomizing chamber 1215 is defined by the distance between the two limiting walls R21, R22, and the closer the distance between the two limiting walls R21, R22 is, the smaller the length of the atomizing chamber 1215 is, the farther the distance between the two limiting walls R21, R22 is, the longer the length of the atomizing chamber 1215 is. The space occupied by the atomizing chamber 1215 defined by the two restricting walls R21, R22 prevents the aerosol from being wasted by being inefficiently diffused and helps to make the aerosol more enter the aerosol passage 113 through the air flow passage R1 and the air outlet 1214. In some embodiments, as shown in fig. 9, the bottom ends of the first and second cavities R21 and R22 are open, so that the cavity R6 can be inserted for partial insertion of the first bracket 22 in the power assembly 2, or for insertion by other objects, and the first and second cavities R3 and R4 may have a snap structure therein to be snap-connected with the inserts inserted into the first and second cavities R3 and R4. In other embodiments, the first and second cavities have a filler therein and are solid structures, or the bottom ends of the first and second cavities are closed so that no further foreign objects can be inserted.

Referring to fig. 7 and 8, the second bracket 121 is further provided with an air hole B1 and an avoiding groove B2, a first end of the air hole B1 is communicated with the liquid guide hole 1211, a second end B11 is communicated with the avoiding groove B2, and the avoiding groove B2 is connected with the second end B11 of the air hole B1 and the atomizing cavity 1215. Air can enter the liquid guide hole 1211 through the avoiding groove B2 and the air hole B1, so that the air pressure between the liquid guide hole 1211 or the liquid storage cavity 111 and the outside is balanced, and the liquid matrix is prevented from being difficult to enter the liquid containing space 1233 on the atomizing core 123 due to the pressure difference, or the liquid in the liquid containing space 1233 is difficult to permeate into the porous body 1231, so that the conduction rate of the liquid matrix in the porous body 1231 is influenced.

However, the existence of the air hole B1 inevitably causes the liquid matrix in the liquid guiding hole 1211 to permeate through the air hole B1, that is, the air hole B1 may cause the liquid leakage from the liquid guiding hole 1211, in order to prevent the liquid leakage from contaminating the atomizer 1 or the power module 2, the first liquid storage portion A1 is provided, the guiding groove B2 is communicated with the atomizing cavity 1215 through the first liquid storage portion A1, and the liquid matrix permeating through the air hole B1 is guided to the first liquid storage portion A1 by the avoiding groove B2 and is locked by the first liquid storage portion A1.

In one embodiment, the second end B11 of the air hole B1 is disposed on the inner surface of the second frame 121 and is communicated with the atomizing chamber 1215, so that the air in the atomizing chamber 1215 can enter the liquid guide 1211 through the air hole B1 from the inside, the first reservoir A1 can be disposed on the outer surface or the inner surface of the second frame 121, and the bypass groove B2 provides a path for the liquid substrate seeped out from the air hole B1 to enter the first reservoir A1.

In another embodiment, as shown in fig. 8, the second end B11 of the air hole B1, the avoiding groove B2 and the first liquid storage portion A1 are disposed on the outer surface of the second bracket 121 to facilitate the manufacturing of the second bracket 121.

Referring to fig. 8, the avoiding groove B2 is curved to increase the liquid locking capacity of the avoiding groove B2, and the liquid storage capacity is increased by increasing the physical length of the avoiding groove B2. Furthermore, the width of the avoiding groove B2 is smaller than the aperture of the second end B11 of the air hole B1, so that the amount of the liquid matrix entering the avoiding groove B2 from the second end B11 of the air hole B1 is limited, more liquid matrix can be locked in the air hole B1, and liquid leakage caused by the liquid matrix permeating out through the air hole B1 can be effectively prevented. And/or further, the avoiding groove B2 comprises a transverse extending part and a longitudinal extending part, the transverse extending part extends along the transverse direction and is transversely connected with the second end B11 of the air hole B1, namely, the joint between the avoiding groove B2 and the air hole B1 is staggered under the air hole B1, so that the oil sealing capacity of the air hole B1 is improved, the outward permeation speed of a liquid matrix through the air hole B1 is reduced, and oil leakage and liquid leakage can be effectively reduced. The longitudinally extending portion of the avoidance groove B2 extends in the longitudinal direction and is longitudinally connected to the first reservoir portion A1. The length of the transverse extension part can be smaller than that of the longitudinal extension part so as to accelerate the emptying speed of the avoiding groove B2 and prevent the liquid substrate from blocking the avoiding groove B2 and influencing the air entering the air hole B1 through the avoiding groove B2. The lateral and longitudinal extensions may be excessive by an arcuate slot. Preferably the lateral extension is substantially perpendicular to the longitudinal extension. And/or further, the pore size of the second end B11 of the air hole B1 is larger than that of the first end thereof, so as to facilitate the air entering and block the liquid matrix from flowing out.

Referring to fig. 7 and 8, the first liquid storage portion A1 includes a plurality of first fins a11 disposed on an outer surface or an inner surface of the second bracket 121, a first transverse groove a12 is formed between two adjacent first fins a11, and a first longitudinal conduction portion a13 is disposed on the first fin a11 between two adjacent first transverse grooves a12, so that the two adjacent first transverse grooves a12 are communicated with each other, and the avoidance groove B2 passes through one first fin a11 to communicate with the corresponding first transverse groove a12, so that the liquid matrix can be introduced into the first transverse groove a12, and the liquid matrix flows in the first liquid storage portion A1 and is stored. Referring to fig. 7 and 8, the width of the first transverse groove a12 is greater than the width of the avoiding groove B2 to increase the liquid locking capacity of the first transverse groove a12, and specifically, the width of the first transverse groove a12 may be 2 to 10 times of the width of the avoiding groove B2, but not limited thereto.
