Description

Technical Field

[0001] This utility model relates to the field of electronic atomization technology, and in particular to an atomizing device and its electronic atomizer. Background Technology

[0002] The existing atomizing device's heating structure mainly consists of three parts: a heating resistance wire, an oil-conducting material that wraps around the resistance wire, and a bushing that secures the oil-conducting material and the resistance wire.

[0003] During the production and use of the product, it was found that because the oil indirectly contacts the resistance wire for heating and atomization through the oil-conducting material, it is difficult to synchronize the atomization speed of the resistance wire with the oil absorption speed of the oil-conducting material. When the oil absorption speed of the oil-conducting material is too fast, it causes oil leakage or incomplete atomization, resulting in poor taste. When the oil absorption speed of the oil-conducting material is slow, it causes the oil-conducting material to dry burn and produce a taste.

[0004] In addition, after working for a long time in the high temperature and high humidity environment of the atomizing core, the oil-guiding material is prone to expansion and deformation, which leads to changes in the size of the air passage, affecting the taste. At the same time, the oil absorption and locking conditions change, making it easier to leak oil and affecting the atomization effect.

[0005] Meanwhile, due to the unstable smoke output, the flue gas channel is hot and cold, which generates condensed oil that cannot be used in the equipment, resulting in oil leakage and waste. Utility Model Content

[0006] The technical problem to be solved by this utility model embodiment is to provide an atomizing device that solves the problems of poor atomization and smoke production effect caused by oil contacting the oil guiding material with the resistance wire, and oil leakage and waste caused by unstable smoke production and condensation of oil that cannot be used in the equipment.

[0008] The atomizing assembly includes a sealing base, an atomizing tube fixed to the sealing base and connected to the air intake hole, and a heating element disposed on the inner wall of the atomizing tube.

[0013] Furthermore, the oil inlet section consists of several oil inlet holes arranged in the atomizing tube.

[0014] Furthermore, the vent portion consists of a plurality of vents arranged at the bottom of the mounting groove.

[0015] Furthermore, the gap width between the spacer and the atomizing tube is 0.6~1.5mm.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the following illustrative embodiments and descriptions are only used to explain the present invention and are not intended to limit the present invention. Moreover, the embodiments and features in the embodiments of the present invention can be combined with each other unless otherwise specified.

[0027] like Figure 1-4 As shown, an optional embodiment of this utility model provides an atomizing device, including a hollow mouthpiece 1 and a housing 2. An oil storage chamber 3 is provided inside the housing. An air intake hole 20 is provided at the top of the housing 2. The mouthpiece 1 is connected to the outside of the air intake hole 30. An atomizing component 4 is disposed through the oil storage chamber 3. The device also includes a lower housing 5 with an air inlet 50. The lower housing 5 abuts against the atomizing component 4 and is connected to the housing 2 as a whole.

[0028] The atomizing assembly 4 includes a sealing base 41, an atomizing tube 42 fixed to the sealing base 41 and connected to the air intake 20, and a heating element 43 disposed on the inner side wall of the atomizing tube 42.

[0029] The atomizing tube 42 is provided with an oil inlet 420 in the circumferential direction. The oil inlet 420 penetrates the inside and outside of the atomizing tube 42. The heating element 43 is attached to the position of the oil inlet 420 on the inner side wall of the atomizing tube 42.

[0030] The sealing base 41 is provided with an installation groove 411, and the bottom of the installation groove 411 is provided with a vent 410 for receiving condensed oil. The atomizing tube 42 is inserted into the installation groove 411 and fixed to the sealing base 41. The vent 410 is connected to the inside of the atomizing tube 42.

[0031] The air inlet 50, the air vent 410, the inner cavity of the atomizing tube, the air intake 20, and the nozzle 1 are connected in sequence to form an air passage.

[0032] In this embodiment, the process of supplying oil to the heating element 43 is simplified, allowing the oil to directly contact the heating element 43 and be atomized. At the same time, by providing an air hole 410 at the bottom of the mounting groove 411 to receive the condensed oil, the intake airflow is used to backflush the condensed oil so that it contacts the heating element 43 and is atomized for use.

[0033] When the user inhales, the airflow enters through the air inlet 50 of the lower housing 5, the air vent 410, the inner cavity of the atomizing tube, the air intake 20, and the mouthpiece 1 in sequence. The airflow creates negative pressure, and the oil in the oil tank 3 enters through the oil inlet 420 circumferentially provided in the atomizing tube 42 and comes into contact with the heating element 43 for atomization. At the same time, the condensed oil produced during inhalation drips into the mounting groove 411 of the sealing base 41 and is collected by the air vent 410. When the user inhales again, the airflow blows the condensed oil through the air vent 410 into the inner cavity of the atomizing tube, so that it comes into contact with the heating element 43 and is atomized for use.

[0034] like Figure 3 , 4 As shown, in an optional embodiment of the present invention, the atomizing component 4 further includes a spacer 44 disposed in the oil storage tank 3. The spacer 44 is partially fitted around the atomizing tube 42 and maintains a gap with the atomizing tube 42 to block the oil inlet 420. The bottom of the spacer 44 is connected to the sealing base 41.

[0035] In this embodiment, a spacer 44 is provided around the atomizing tube 42 and maintains a gap with the atomizing tube 42 to block the oil inlet 420. The spacer 44 blocks the oil inlet 420, which avoids the oil in the oil tank 3 from directly impacting the oil inlet 420 and causing oil leakage during operation without affecting the oil inlet. At the same time, since there is a gap between the spacer 44 and the oil inlet 420, the viscosity of the oil increases the flow resistance of the oil and it will stagnate in the gap, further preventing the oil from impacting the oil inlet 420 and causing oil leakage. In addition, it can also maintain the stable oil inlet of the oil inlet 420.

[0036] like Figure 3 As shown, in another optional embodiment of this utility model, the oil inlet 420 is a plurality of oil inlet holes 4200 arranged in the atomizing tube. In this embodiment, oil is introduced through the oil inlet holes 4200. The oil is affected by viscosity and surface tension, and stays in the oil inlet holes 4200 to contact the heating element 43 and atomize.

[0037] like Figure 3 As shown, in another optional embodiment of this utility model, the vent portion 410 consists of a plurality of vents 4100 arranged at the bottom of the mounting groove 411. In this embodiment, the vents 4100 absorb condensed oil. Due to the influence of viscosity, surface tension, and size of the vents 4100, the condensed oil remains in the vents 4100.

[0038] like Figure 4As shown, in another optional embodiment of this utility model, the gap width between the spacer portion 44 and the atomizing tube 42 is 0.6~1.5mm. In this embodiment, the gap width value between the spacer portion 44 and the atomizing tube 42 is adapted according to the viscosity of the atomized oil. A table of matching parameters for different oil viscosities is attached below.

[0039] like Figure 3 As shown, in another optional embodiment of this utility model, the diameter of the oil inlet 4200 is 0.2~0.4mm. In this embodiment, the diameter of the oil inlet 4200 is adapted to the viscosity of the atomized oil, and oil inlets 4200 of different diameters can be mixed and used to adapt to complex working conditions. A table of matching parameters for different oil viscosities is attached below.

[0040] like Figure 3 As shown, in an optional embodiment of this utility model, the diameter of the vent 4100 is 0.35~0.8mm. In this embodiment, the diameter of the vent 4100 can be adjusted according to the specific requirements of the air intake and the viscosity of the atomized oil. At the same time, vents 4100 with different diameters can be mixed to adapt to complex working conditions. A table of matching parameters for different oil viscosities is attached below.

[0041]

[0042] like Figure 3 As shown, in another optional embodiment of the present invention, the spacer portion 44 is further provided with a turbulence portion 441 in the circumferential direction.

[0043] In this example, a turbulence-disrupting part 441 is also provided around the partition ring 44. The turbulence-disrupting part 441 divides the space inside the oil tank 3, further preventing the oil from oscillating inside the oil tank 3 and causing oil leakage.

[0044] like Figure 4 As shown, in another optional embodiment of this utility model, a leak-proof cavity 52 is also provided inside the lower housing 5, and the leak-proof cavity is provided with a baffle 521.

[0045] In this embodiment, a leak-proof cavity 52 is provided in the lower housing 5, and a baffle 521 is provided in the leak-proof cavity 52. ​​When the amount of condensed oil dripping during the sucking process exceeds the receiving range of the air hole 410, the excess oil drips from the air hole 410 into the leak-proof cavity 52 for storage. At the same time, in order to prevent the oil in the leak-proof cavity 52 from flowing out of the air inlet 50, a baffle 521 is provided between the air inlet 50 and the leak-proof cavity 52 to prevent the oil from flowing out of the air inlet 50 without affecting the air intake.

[0046] On the other hand, the present invention also adopts the following technical solution: an electronic atomizer, including the atomizing device described above.
