Referring to fig. 1-3, the present invention provides an atomizing device, which includes a cover 1, a base 2, an atomizing assembly 3, and an oil sucking member 4. The cover body 1 is a hollow structure, one end of which is provided with a suction port 11, and the other end of which is provided with an opening 12. The base 2 closes the opening 12 and encloses an oil storage chamber 5 with the cover 1. One end of the atomization component 3 is inserted into the base 2, and the other end is inserted into the suction port 11, so as to form an atomization channel 6 which penetrates through the oil storage cavity 5. The periphery of atomization component 3 is equipped with an at least intercommunication the oil guide hole 311 of oil storage chamber 5 and atomizing passageway 6, inhale oil piece 4 cup joint in atomization component 3's periphery, and one end with base 2 butt, the other end covers at least one oil guide hole 311. This embodiment utilizes the interior fluid of capillary phenomenon absorption oil storage chamber 5 through inhaling oil piece 4, via leading oilhole 311 entering atomizing passageway 6 again, has slowed down the rate that fluid got into atomizing passageway 6 to the probability of fluid from 6 seepage of atomizing passageway has been reduced.

In the present embodiment, as shown in fig. 1 and 2, the atomizing assembly 3 includes an atomizing pipe 31, an oil guide member (not shown), and a heating member 32. One end of the atomizing pipe 31 penetrates through the base 2 and is communicated with the outside, and the other end of the atomizing pipe is connected with the suction port 11 to form an atomizing channel 6 penetrating through the oil storage cavity 5, so that the air inlet end of the atomizing channel 6 is located on the base 2, and the air outlet end of the atomizing channel is located on the suction port 11. After entering the atomizing channel 6 from the atomizing pipe 31 through one end of the base 2, the outside air participates in atomization and then flows out from the suction port 11. In practical application, the base 2 may be provided with an installation hole 21 for inserting the atomizing pipe 31, and the inner wall of the installation hole 21 is provided with soft glue, so that the atomizing pipe 31 is inserted into the base 2 in a sealing manner, and the oil storage chamber 5 is sealed. The heating member 32 has a hollow cylindrical structure formed by winding a heating wire or a heating net. The oil guide member is sleeved on the periphery of the heating member 32 and surrounds the heating member 32 to form a vent hole coaxial with the atomizing passage 6. The oil guide member may be made of oil guide wool and/or porous ceramic material, and may be separately connected to the heating member 32 or integrally formed therewith. The side wall of the atomizing pipe 31 is provided with at least one oil guide hole 311, and the oil guide member is located at a portion of the atomizing pipe 31 where the oil guide hole 311 is provided. That is, one end of the oil guide hole 311 is exposed to the oil storage chamber 5, and the other end is covered by the oil guide member, so that the oil in the oil storage chamber 5 enters the atomizing channel 6 through the oil guide hole 311, is firstly absorbed by the oil guide member, is then heated and atomized by the heating member 32, and finally flows out of the suction port 11.

In this embodiment, as shown in fig. 2, the oil suction member 4 is sleeved on the outer circumference of the atomizing pipe 31 and covers at least one oil guiding hole 311. Therefore, the oil in the oil storage chamber 5 is absorbed by the oil absorption member 4, enters the atomization passage 6 through the oil guide hole 311, and is finally absorbed by the oil absorption member 4, so that the speed of the oil entering the atomization passage 6 is slowed down. Correspondingly, the oil suction member 4 is provided with a through hole 41 adapted to the atomizing pipe 31, and the inner diameter of the through hole 41 is slightly smaller than the outer diameter of the atomizing pipe 31, so that the oil suction member 4 is sleeved on the outer diameter of the atomizing pipe 31 in an interference manner, and oil is prevented from entering the oil guide hole 311 from a gap between the oil suction member and the atomizing pipe. Preferably, a gap exists between the oil absorbing member 4 and the inner wall of the cover body 1. That is, the thickness of the oil sucking member 4 in the radial direction is smaller than the distance between the inner wall of the cover body 1 and the outer periphery of the atomizing pipe 31. Therefore, the oil in the oil storage chamber 5 can flow in the gap, which is beneficial to increasing the flow efficiency of the oil and promoting the oil absorption of the oil absorption piece 4. In practical application, the oil absorbing member 4 is made of a porous material or a fiber material, and a capillary effect is formed in the oil storage cavity by utilizing the liquid absorption performance of the porous material or the fiber material, so that oil liquid with the liquid level lower than the oil guide hole is conveyed into the oil guide hole. For example, the oil absorbing member 4 can be made of fiber foam, pure cotton woven cloth, long stapled cotton, dust-free paper, porous ceramic, or the like.

Further, as shown in fig. 1 and 2, a limiting ring 312 is protruded from the outer circumference of the atomizing pipe 31, and at least one oil guide hole 311 is located between the limiting ring 312 and the base 2. That is, the stopper ring 312 is located above the oil guide hole 311. An annular mounting groove 8 is defined between the limiting ring 312 and the base 2, and the height of the annular mounting groove 8 is matched with the length of the oil absorbing piece 4 in the axial direction. The oil suction piece 4 is sleeved on the periphery of the atomizing pipe 31 and covers the oil guide hole 311, one end of the oil suction piece 4 is abutted against the limiting ring 312, and the other end of the oil suction piece is abutted against the base 2. On one hand, the displacement of the oil suction member 4 in the axial direction is limited by the annular limiting groove, so that a gap between the oil suction member 4 and the atomizing pipe 31 is avoided, or the oil suction member 4 moves downwards under the action of gravity to expose the oil guide hole 311. On the other hand, because the oil absorbing piece 4 is abutted with the base 2, the oil received by the base 2 can be completely absorbed by the oil absorbing piece 4, so that the waste of the oil is avoided. The position of the limiting ring 312 may be just higher than the oil guiding hole 311, and correspondingly, the length of the oil absorbing member 4 just covers the oil guiding hole 311. The position of the limit ring 312 may also have a distance from the oil guide hole 311 in the axial direction, and correspondingly, there is a margin after one end of the oil suction member 4 abutting against the limit ring 312 covers the oil guide hole 311. In practical application, the margin of the increase can be set according to practical requirements. The limiting ring 312 may be integrally formed with the atomizing pipe 31, or may be separately connected to the atomizing pipe 31, and may be made of a hard material or a soft plastic material, which is not limited herein.

In this embodiment, as shown in fig. 2, the oil guide hole 311 may be one, two or more. When the number of the oil guide holes 311 is two or more, the central axis of each oil guide hole 311 is located on the same plane and is uniformly distributed along the circumferential direction of the atomizing tube 31. Because the liquid level of the oil in the liquid storage cavity is approximately perpendicular to the axial direction of the atomizing pipe 31, the surface passing through the central axis of the oil guide hole 311 and perpendicular to the axial direction of the atomizing pipe 31 is marked as the interface 10. The interface 10 divides the oil reservoir chamber 5 into two parts, which are respectively designated as a first oil reservoir space 501 and a second oil reservoir space 502. Wherein the first oil storage space 501 is located at one side of the interface 10 and close to the suction port 11; the second oil storage space 502 is located at the other side of the interface 10 and close to the base 2. The capacity of the second oil storage space 502 is not less than the capacity of the first oil storage space 501. When the oil chamber 5 filled with the oil is put into use, the oil in the oil chamber 5 is consumed to generate a negative pressure at an end of the oil chamber 5 close to the suction port 11, that is, a negative pressure is first generated in the first oil storage space 501 to form a pressure difference with the external atmospheric pressure. Therefore, the oil in the oil reservoir chamber 5 is less likely to flow into the oil guide hole 311 under the pressure of the atmospheric pressure, that is, under the pull of the negative pressure. However, as the oil in the oil storage chamber 5 decreases, the pressure difference between the negative pressure in the oil storage chamber 5 and the external atmospheric pressure gradually decreases, that is, the pressure of the external atmospheric pressure on the oil in the oil storage chamber 5 gradually decreases, that is, the pulling force of the negative pressure in the oil storage chamber 5 on the oil in the oil storage chamber 5 gradually decreases, so that the speed of the oil in the oil storage chamber 5 entering the oil guide hole 311 gradually increases as the oil amount decreases.

Referring to fig. 2, in the embodiment, the position of the oil guide hole 311 in the axial direction of the atomizing pipe 31 is increased to a position where the capacity of the second oil storage space 502 is greater than or equal to the capacity of the first oil storage space 501, so that when oil in the first oil storage space 501 with a smaller capacity is consumed, the speed of the oil entering the oil guide hole 311 is delayed mainly by the action between the atmospheric pressure and the negative pressure, and the probability of leakage of the oil from the atomizing passage 6 is reduced. When the oil in the first oil storage space 501 is consumed, the liquid level of the oil in the oil storage chamber 5 is lower than the oil guide hole 311, so that at this stage, the oil in the second oil storage space 502 can only be absorbed to the oil guide hole 311 through the capillary effect of the oil absorption member 4, thereby achieving the effect of delaying the oil from entering the oil guide hole 311 and preventing the oil from leaking. It should be noted that the interface 10 is a virtual interface 10, which does not physically separate the liquid storage cavity into two liquid storage spaces, and there is no physical space between the first liquid storage space and the second liquid storage space, and the two liquid storage spaces are completely communicated.

Preferably, the capacity of the first oil storage space 501 is equal to the capacity of the second oil storage space 502. Therefore, on the basis of ensuring no oil leakage, the oil guiding speed is considered, and the smoke quantity is improved. Of course, in practical applications, the positions of the oil guide holes 311 can be set according to the actual capacity of the oil storage chamber 5, the size and number of the oil guide holes 311, the oil absorption efficiency of the oil absorption member 4, and other factors, so as to adjust the capacities of the first oil storage space 501 and the second oil storage space 502.

In this embodiment, as shown in fig. 3, the atomization device further comprises a seal bar 7. The sealing rod 7 is detachably inserted into the atomizing channel 6 from the suction port 11 and is in interference fit with the atomizing channel 6. That is, the sealing rod 7 is located in a part of the ventilation hole surrounded by the heating member 32 and the oil guide member, and the outer periphery of the part elastically abuts against the inner wall of the ventilation hole 41 to block the air inlet end of the atomizing passage 6 and the oil guide hole 311. Meanwhile, the sealing rod 7 is positioned at the inner part of the suction port 11, and the periphery of the sealing rod is elastically abutted against the inner wall of the suction port 11 so as to seal the air outlet end of the atomizing channel 6. The seal rod 7 is used for simultaneously sealing the air inlet end and the air outlet end of the atomizing channel 6 and the oil guide hole 311, so that the oil liquid in the oil storage cavity 5 of the atomizing device in the storage and transportation processes is prevented from permeating into the atomizing channel 6 from the oil guide hole 311 and finally leaking from the atomizing channel 6. As shown in fig. 2, when the user starts to use the atomizer, the user only needs to pull the sealing rod 7 out of the atomizing passage 6 from the suction port 11, which is convenient to operate.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
