Description

Technical Field

[0001] The utility model relates to the technical field of electronic atomization devices, and in particular to an atomizer and an electronic atomization device. Background Art

[0002] At present, the ventilation pipe of the atomizer is generally connected to the screw by riveting. During the inhalation process, the high-temperature steam flowing into the ventilation pipe at normal temperature will produce condensation due to the alternation of hot and cold. The condensation will leak out from the air inlet holes on the screw and the electrode, reducing the customer's inhalation experience. Moreover, the atomizer generally uses a ceramic atomization core for atomization. However, in actual use, it is impossible to achieve a state where the atomization liquid that penetrates into the ceramic atomization core is just completely atomized, so that excess atomization liquid will accumulate at the bottom of the ventilation pipe, increasing the risk of leakage.

[0003] In the related art, in order to alleviate the leakage of condensed liquid and excess atomized liquid from the air inlet, a solution of arranging absorbent cotton at the bottom of the ventilation pipe is adopted. However, due to the small diameter of the ventilation pipe, only a small amount of absorbent cotton can be loaded, and the position of the absorbent cotton is close to the ceramic atomization core. If the assembly is not careful, it may contact the ceramic and cause the risk of liquid conduction. It cannot really alleviate the leakage of liquid and condensed liquid. Utility Model Content

The atomizer is integrally connected to the battery rod assembly or detachably connected, the battery rod assembly is used to power the atomizer, and the atomizer is used to heat the atomization liquid to atomize and generate an aerosol when powered on.

[0036] See also Figures 1 to 7 The atomizer includes a liquid storage component 10, a ventilation tube 4, an atomizing core 7, a base 1, a liquid absorbing component 3 and a liquid blocking component 5. The liquid storage component 10 is provided with a liquid storage cavity 1011; the ventilation pipe 4 has an atomization section 41 penetrating the liquid storage cavity 1011 and an air intake section 42 located outside the liquid storage cavity 1011, and the side wall of the air intake section 42 is provided with a first liquid passage hole 421; the atomization core 7 is arranged in the atomization section 41 and is connected with the liquid storage cavity 1011; the base 1 is provided with a accommodating cavity 11 for accommodating the air intake section 42, and a liquid storage space connected with the first liquid passage hole 421 is formed between the outer peripheral wall of the air intake section 42 and the inner peripheral wall of the accommodating cavity 11, and the base 1 is also provided with a first air intake hole 12 connected with the air intake section 42, and the first air intake hole 12 is farther away from the atomization section 41 relative to the liquid storage space; the liquid absorption component 3 is arranged in the liquid storage space; the liquid blocking component 5 is arranged in the air intake section 42, and the liquid blocking component 5 is used to drain the leaked liquid or condensed liquid in the atomization section 41 to the first liquid passage hole 421.

[0037] Since a liquid storage space is formed between the outer peripheral side of the air inlet section 42 and the inner peripheral wall of the accommodating cavity 11 of the base 1, and the liquid absorbent member 3 is arranged in the liquid storage space, the size of the liquid absorbent member 3 is not limited by the size of the internal space of the vent pipe 4, and the space and size that can be set are relatively free, so that a sufficient number of liquid absorbent members 3 can be set to increase the storage capacity of the liquid, effectively alleviating the leakage of condensed liquid and excess atomized liquid from the first air inlet hole 12. In addition, through the liquid blocking effect of the liquid blocking member 5, the condensed liquid or leaked liquid formed in the atomizing section 41 is guided to the first liquid passing hole 421, and enters the liquid storage space through the first liquid passing hole 421, so that when the liquid absorbent member 3 is in a saturated state, the liquid blocking effect still exists, further reducing the risk of leakage or condensed liquid blocking the first air inlet hole 12.

[0038] It should be noted that, since a liquid storage space is formed between the outer peripheral side of the air inlet section 42 and the inner peripheral wall of the accommodating cavity 11 of the base 1, and the liquid absorbing member 3 is arranged in the liquid storage space, direct contact between the liquid absorbing member 3 and the atomizing core 7 can be avoided to prevent burns.

The second mounting groove 231 is located in the first mounting groove 221. For example, the first mounting groove 221 is an annular groove, which is conducive to the arrangement of more liquid-absorbing parts 3. The second mounting groove 231 is adapted to the vent pipe 4, so that the vent pipe 4 is conveniently installed in the second mounting groove 231.

The plurality of first liquid-passing holes 421 and the plurality of second liquid-passing holes 232 are arranged opposite to each other, ensuring that the condensed liquid and the atomized liquid flow into the first mounting groove 221 through the first liquid-passing holes 421 and the second liquid-passing holes 232; for example, three first liquid-passing holes 421 are provided, and three second liquid-passing holes 232 are provided, and the three first liquid-passing holes 421 and the three second liquid-passing holes 232 are arranged opposite to each other. According to actual needs, the longitudinal section of the support cover 2 can be U-shaped, and one, two, four, etc. of the first liquid passage holes 421 and the second liquid passage holes 232 can be provided.

[0043] According to actual needs, the support cover 2 can be a steel cover, which is small in size and can avoid taking up too much space; the base 1 can be a screw, and the air inlet section 42 of the ventilation pipe 4 is fixed to the inner wall of the second mounting groove 231 by riveting, and the support cover 2 is fixed to the inner wall of the accommodating cavity 11 by riveting, thereby realizing the mutual fixation between the base 1 and the ventilation pipe 4.

[0044] See also Figure 2 , Figure 4 and Figure 7 The atomizer further includes a sealing member 8 fixed to the bottom wall 21.
