Detailed Description

See fig. 1 and 2. Fig. 1 shows a schematic perspective exploded view of an electronic atomizer according to an embodiment of the present disclosure, and fig. 2 shows a schematic sectional view of the electronic atomizer of the embodiment.

As can be seen from fig. 1 and 2, the electronic atomizer comprises a liquid storage shell 4, a gas guide tube 3 arranged in the liquid storage shell 4, and an atomization assembly 1 arranged in the gas guide tube 3, and has a gas passage penetrating through the gas guide tube 3 and the atomization assembly 1. A liquid storage cavity is defined between the liquid storage shell 11 and the air guide tube 12, the liquid storage cavity is sealed by the cover component 5, and the side wall of the air guide tube 3 is provided with an air guide tube liquid inlet hole 31 c. The atomization component 1 comprises a sleeve 11 and a heating core 12 arranged in the sleeve 11, and a sleeve liquid inlet hole 11c corresponding to the gas-guide tube liquid inlet hole 33 is arranged on the side wall of the sleeve 11. When the smoking works, the smoke liquid (tobacco oil) enters the heating core 12 from the air duct liquid inlet hole 31c and the sleeve pipe liquid inlet hole 11c for atomization.

Preferably, the sleeve 11 may be a metal sleeve. Preferably, the heat generating core 12 includes a heat generating core body made of a porous material (e.g., porous ceramic) and a heat generating element disposed within the heat generating core body. Preferably, the sleeve 11 and the heat generating core 12 are sintered into a single body to form the atomizing assembly 1.

The gas-guiding tube 3 comprises a first tube section 31 at the lower part and a second tube section 32 at the upper part, the diameter of the first tube section 31 being larger than the diameter of the second tube section 32, so that a receiving cavity for receiving the atomization assembly 1 is formed in the first tube section 31.

As can be seen from fig. 1 and 2, the first tube section 31 of the gas-guide tube 3 comprises a first tube section lower part 31a and a first tube section upper part 31 b. The lower portion 31a of the first tube section has an outer diameter greater than the outer diameter of the upper portion 31b of the first tube section to facilitate sealing engagement with the inner surface of the reservoir housing 4 to form the bottom of the reservoir chamber. The gas-guide tube inlet hole 31c is formed on the first tube section upper portion 31 b.

Referring collectively to fig. 4, there is shown an enlarged partial cross-sectional view of the electronic atomizer of fig. 2. The inner surface of the airway tube 3, which is matched with the sleeve 11, is provided with an annular boss, and the annular boss is formed at the upper end of the side surface of the accommodating cavity. As can be seen in fig. 4, a boss mating surface c is formed between the outer surface of the sleeve 11 and the annular boss of the airway tube 3. The boss matching surface c is an interference matching surface, and an upper sealing structure positioned above a liquid inlet position (the position of the liquid inlet hole 31c of the gas guide tube and the liquid inlet hole 11c of the sleeve tube) is formed between the upper end of the sleeve tube 11 and the gas guide tube 3.

As can also be seen from fig. 1, 2 and 4, the electronic atomizer further comprises a bottom seal 2, the bottom seal 2 having a first sealing section at a lower portion and a second sealing section at an upper portion, wherein the first sealing section has an outer diameter larger than the diameter of the second sealing section.

As can be seen in fig. 4, a first mating surface a of the sealing member is formed between the first sealing section and the first tube section 31 of the airway tube 3, and a second mating surface b of the sealing member is formed between the second sealing section and the inner surface of the sleeve 11. The first fitting surface a and the second fitting surface c of the sealing element jointly form a lower sealing structure which is formed between the lower end of the sleeve 11 and the gas guide tube 3 and is positioned below the liquid inlet position (the position where the gas guide tube liquid inlet hole 31c and the sleeve liquid inlet hole 11c are positioned).

In this embodiment, set up sleeve pipe 11 on atomization component 1 to form interference fit through sleeve pipe 11 and air duct 3, like this, when installation atomization component 1, with sleeve pipe 11 together with set up the core 12 that generates heat in it pack into air duct 3 together can, compare with traditional scheme, save the loaded down with trivial details process of assembly imbibition component (like package cotton), promote production efficiency greatly. Moreover, because the upper end and the lower end of the sleeve 11 are both provided with sealing structures used for sealing the air duct 3, the leakage of the bottom of the atomization component or the leakage of the smoke liquid into the air channel can be prevented to cause the blockage of the air duct and influence the use experience.

In this embodiment, the boss fitting surface c between the outer surface of the sleeve 11 and the annular boss of the first tube section 31 of the air guide tube 3 is an interference fitting surface, so that the upper sealing structure can be quickly formed through a riveting (axial press fitting) process, the upper sealing structure is simplified, and the atomization assembly 1 is more reliably fixed in the air guide tube 3.

In this embodiment, the first mating surface a of the sealing element between the bottom sealing element 2 and the gas-guiding tube 3 and the second mating surface b of the sealing element between the bottom sealing element and the sleeve 11 form a secondary seal, so that the lower sealing structure can better prevent the bottom of the atomization assembly from leaking liquid.

Preferably, the first sealing element matching surface a and the second sealing element matching surface b which form the lower sealing structure are interference matching surfaces. Thus, the sealing structure can be quickly formed through the riveting (axial press fitting) process, the form of the sealing structure is simplified, and reliable fixation can be realized.

As can be seen in fig. 4, an annular boss is formed at the upper end of the side surface of the receiving chamber, and a gap x is formed between the region of the side surface of the receiving chamber below the annular boss and the outer surface of the sleeve 11.

In this embodiment, since a gap is formed between the region of the side surface of the accommodating cavity below the annular boss and the outer surface of the sleeve 11, and the gap serves as a clearance design structure, the interference press-fitting stroke of the sleeve 11 when the atomizing assembly is axially installed in the accommodating cavity can be reduced, so that the installation is more labor-saving. Moreover, when the atomization assembly is axially installed, before interference fit begins, the alignment of the sleeve liquid inlet hole 11c and the gas guide tube liquid inlet hole 31c can be conveniently adjusted by freely rotating the atomization assembly. In addition, since the interference fit face c exists only at the upper end of the side surface of the accommodation cavity, the risk of damage to the heat generating core 12 of the sleeve 11 due to interference pressing is greatly reduced.

As can also be seen from fig. 4, the upper end of the heat generating core 12 is lower than the lower end of the annular boss by a predetermined distance S. Because the upper end of the heating core 12 is lower than the lower end of the annular boss by a preset distance S, the heating core can be enabled to avoid a stress position when the atomization assembly is axially pressed, and the risk of damage to the heating core 12 caused by interference extrusion is further reduced.

It can also be seen from fig. 4 that the tip of the cannula 11 abuts the top surface of the receiving cavity. Because the top end of the sleeve 11 abuts against the top surface of the accommodating cavity, when the atomization assembly is axially installed, the atomization assembly is convenient to axially position in the accommodating cavity of the air guide tube 3.

In this embodiment, the sleeve 11 has a plurality of sleeve liquid inlets 11c, and the airway tube 3 has a plurality of corresponding airway tube liquid inlet holes 31 c. As can be seen from FIG. 4, the size of each liquid inlet 11c of the sleeve 11 is larger than that of each liquid inlet hole 31c of the airway tube 3. The structure that the large hole (the sleeve liquid inlet hole 11c) on the sleeve 11 corresponds to the small hole (the air duct liquid inlet hole 31c) on the air duct 3 is adopted, so that accurate alignment is not needed during assembly, higher assembly efficiency is realized, and the liquid supply effect is ensured.

Referring to fig. 3a and 3b, in the present embodiment, a core body protrusion extending outward and filling in the casing liquid inlet hole 11c of the casing 11 is formed on the outer surface of the heat generating core body. Preferably, the core body projections are flush with the outer surface of the sleeve 11. In the present embodiment, the heat generating core body and the sleeve 11 may be formed as an integral sintered structure.

In this embodiment, by filling the core body protrusion of the heat generating core body in the casing liquid inlet hole 11c, the heat generating core 12 and the casing 11 can be better combined together with better integrity.
