Description

Technical Field

[0001] The utility model relates to the technical field of atomizers, and particularly relates to an atomizer. Background Art

[0002] Atomizers usually adopt a structure design with oil core separation, that is, the fluid channel between the liquid storage chamber and the atomization chamber is isolated. Existing atomizers use a traditional single-layer porous oil storage cotton structure as the isolation. When the liquid storage chamber is affected by environmental temperature or negative pressure, the material in the liquid storage chamber enters the oil storage cotton through the fluid channel. Since the oil storage cotton has no extra space to buffer the oozing material, the material overflows from the oil storage cotton to the atomization chamber through the fluid channel, resulting in material leakage. Summary of the Utility Model

[0003] The main purpose of the utility model is to propose an atomizer, which can solve the problem of material leakage existing in the atomizer in the prior art.

[0004] To achieve the above purpose, the present application provides an atomizer, including:

[0005] An outer chamber for storing materials;

[0006] An inner chamber, which is communicated with the outer chamber by a first fluid channel, and the inner chamber is used for receiving the materials in the outer chamber;

[0007] A middle chamber, between which and the inner chamber there are a second fluid channel and a third fluid channel that communicate the middle chamber and the inner chamber longitudinally, and the middle chamber is used for receiving the materials in the inner chamber;

[0008] An atomization chamber, which is arranged in the middle chamber and is communicated with the middle chamber by a fourth fluid channel;

[0009] A first porous medium for absorbing materials, which is arranged in the inner chamber;

[0010] A second porous medium for absorbing materials, which is arranged in the middle chamber.

[0011] When the outer chamber is affected by environmental high temperature or negative pressure, for example, the air in the outer chamber expands and squeezes the materials to transfer into the inner chamber after being heated. The excess materials absorbed by the first porous medium in the middle chamber enter the inner chamber through the second fluid channel under the capillary action. The materials in the inner chamber can be absorbed by the second porous medium under the capillary action, preventing the materials from directly leaking into the atomization chamber. For example, when the materials in the outer chamber are affected by the negative pressure in the middle chamber, the inner chamber or the atomization chamber, the materials transfer to the negative pressure area.

[0012] In some embodiments, the atomizer includes a housing having a receiving space and an atomization chamber. The housing is spaced apart and divided into three relatively independent spaces from the inside to the outside. The outer space serves as the outer chamber, the inner space serves as the inner chamber, and the innermost space is the middle chamber. The atomization chamber is disposed in the middle chamber. Among them, through holes communicating the spaces are provided on the spacer, and the material is transferred in the spaces through the through holes. The through hole communicating the inner chamber and the outer chamber serves as the first fluid passage, and the two longitudinally distributed through holes between the inner chamber and the middle chamber are the second fluid passage and the third fluid passage from bottom to top, and the through hole between the middle chamber and the atomization chamber is the fourth fluid passage.

[0013] In some embodiments, the material stored in the atomizer is a fluid capable of generating an aerosol. To meet the flow requirement of the material in the space, the through holes serve as fluid passages for the material to transfer between multiple chambers. On the spacer between the outer chamber and the inner chamber, the first fluid passage is close to the bottom of the space, which can enable the fluid to reach the state of liquid level balance in the two chambers.

[0014] In some embodiments, the horizontal position of the first fluid passage is lower than the horizontal position of the second fluid passage, which can slow down the time for the fluid to transfer from the outer chamber to the inner chamber. Among them, the third fluid passage is located above the second fluid passage, which can balance the air pressure difference between each chamber in the atomizer and the external atmosphere to facilitate the transfer of the fluid.

[0015] In some embodiments, an atomization core will be configured in the atomization chamber. The atomization core receives the aerosol-forming matrix and atomizes it to form an aerosol for the user to inhale. The atomization core is generally approximately at the same horizontal position as the fluid passage entering the atomization chamber to facilitate the atomization core to quickly receive the aerosol-forming matrix. Further, the second fluid passage and the fourth fluid passage are on the same axis, or at least part of the projection of the second fluid passage overlaps with the projection of the fourth fluid passage.

[0016] In some embodiments, when the material enters the middle chamber from the inner chamber, the material preferentially enters the middle chamber from the second fluid passage with a lower horizontal position, and the third fluid passage serves as a gas passage to balance the air pressure between the middle chamber and the inner chamber. When the liquid level of the material in the middle chamber starts to be higher than the position of the third fluid passage, the third fluid passage can also serve as a flow passage for the material. Further, the flow area of the second fluid passage is larger than that of the third fluid passage.

[0017] In some embodiments, the first porous medium and the second porous medium are made of the same or different materials. Generally, cotton is used as the porous medium in the atomizer to absorb the aerosol-forming matrix. Among them, the first porous medium is disposed in the inner chamber to absorb the material in the outer chamber, and the second porous medium is disposed in the middle chamber to absorb the material overflowing from the inner chamber.

[0018] In some embodiments, the density of the first porous medium is 0.07 g / cm 3 .

[0019] In some embodiments, the unilateral interference amount between the first porous medium and the inner chamber is 0.25 mm, that is, the interference amount between the first porous medium and the inner wall of the inner chamber close to the middle chamber is 0.25 mm, or the interference amount between the first porous medium and the inner wall of the inner chamber close to the outer chamber is 0.25 mm.

[0020] In some embodiments, the second porous medium has a higher density than the first porous medium. For example, the density of the second porous medium is 0.11 g / cm 3 . To better lock the material and reduce the overflow speed of the material.

[0021] In some embodiments, the unilateral interference amount between the second porous medium and the middle chamber is 0.25 mm.

[0022] Compared with the prior art, the air in the outer chamber expands after being heated and squeezes the material to transfer into the inner chamber. The excess material absorbed by the first porous medium in the middle chamber enters the inner chamber through the second fluid channel under the capillary action. The material in the inner chamber can be absorbed by the second porous medium under the capillary action, preventing the material from directly leaking into the atomization chamber. For example, the material in the outer chamber is affected by the negative pressure in the middle chamber, the inner chamber or the atomization chamber, and the material transfers to the negative pressure area.

[0030] See Figures 1 to 3 , the present application provides an atomizer for aerosol generation use, and the atomizer includes:

[0031] An outer chamber 11 for storing materials;

[0032] An inner chamber 21, the inner chamber 21 is communicated with the outer chamber 11 by a first fluid channel 50, and the inner chamber 21 is used to receive the materials in the outer chamber 11;

[0033] A middle chamber 31, there are a second fluid channel 60 and a third fluid channel 70 that longitudinally communicate the middle chamber 31 and the inner chamber 21 between the middle chamber 31 and the inner chamber 21, and the middle chamber 31 is used to receive the materials in the inner chamber 21;

[0034] An atomization chamber 41, which is arranged in the middle chamber 31, and the atomization chamber 41 is communicated with the middle chamber 31 by a fourth fluid channel;

[0035] A first porous medium 22 for absorbing materials, which is arranged in the inner chamber 21;

[0036] A second porous medium 32 for absorbing materials, which is arranged in the middle chamber 31.

[0037] When the outer chamber 11 is affected by the ambient temperature or negative pressure, for example, the air in the outer chamber 11 expands after being heated and squeezes the material to transfer into the inner chamber 21. The excess material absorbed by the first porous medium 22 in the middle chamber 31 enters the inner chamber 21 through the second fluid channel 60 under the capillary action. The material in the inner chamber 21 is absorbed by the second porous medium 32 under the capillary action, which can prevent the material from directly leaking into the atomization chamber 41. For example, the material in the outer chamber 11 is affected by the negative pressure in the middle chamber 31, the inner chamber 21 or the atomization chamber 41, and the material transfers to the negative pressure area.

[0038] Specifically, as Figure 1 shown, in some embodiments, the atomizer includes a housing 10 having a receiving space and an atomization tube 40. The housing 10 is divided into three relatively independent spaces from the inside to the outside by a plurality of partitions. The outer space serves as the outer chamber 11, the inner space serves as the inner chamber 21, and the innermost space is the middle chamber 31. The atomization tube 40 is disposed in the middle chamber 31, and the inside of the atomization tube 40 is defined as an atomization chamber 41 for atomizing the material. Among them, porous media for absorbing the material are respectively disposed in the inner chamber 21 and the middle chamber 31.

[0039] In some embodiments, the housing 10 has a first opening and a second opening that are longitudinally opposite, and the openings are sealed by a sealing seat to form a receiving space in the housing 10. The plurality of partitions divide the receiving space into a plurality of relatively independent chambers, and each chamber can be used to store the material or configure the atomization core 80 according to the requirements of the atomizer.

[0040] The plurality of partitions can all be annular tubes. As Figure 2 shown, the above-mentioned receiving space can be divided into three substantially coaxial spaces by two tubes. The outer space serves as the outer chamber 11, the inner space serves as the inner chamber 21, and the innermost space is the middle chamber 31.

[0041] Through holes communicating adjacent chambers are provided on the partitions, and the material transfers between adjacent chambers through the through holes. As Figure 2 shown, through holes are provided on the first partition 20 as the first fluid channel 50. The first fluid channel 50 communicates the inner chamber 21 with the outer chamber 11, and the first fluid channel 50 is close to the bottom of the outer chamber 11. Two through holes are provided on the second partition 30 as the second fluid channel 60 and the third fluid channel 70 respectively. The second fluid channel 60 and the third fluid channel 70 are longitudinally distributed along the second partition 30, and are the second fluid channel 60 and the third fluid channel 70 from bottom to top respectively to communicate the inner chamber 21 and the middle chamber 31. A fourth fluid channel is provided on the side wall of the atomization tube 40, and the fourth fluid channel communicates the middle chamber 31 with the atomization chamber 41.

[0042] In some embodiments, the horizontal position of the first fluid passage 50 is lower than that of the second fluid passage 60, which can slow down the time for the fluid to transfer from the outer chamber 11 to the inner chamber 21. Among them, the third fluid passage 70 is located above the second fluid passage 60, which can balance the air pressure difference between each chamber in the atomizer and the external atmosphere to facilitate fluid transfer.

[0043] As Figure 3 shown, the second interval 30 between the inner chamber 21 and the middle chamber 31 is provided with a second fluid passage 60 and a third fluid passage 70 longitudinally from bottom to top. Among them, the horizontal position of the second fluid passage 60 is higher than that of the first fluid passage 50. When the material is injected into the outer chamber 11, the material enters the inner chamber 21 through the first fluid passage 50. The first porous medium 22 absorbs the material and is saturated by capillary action. When the liquid level of the excess material in the inner chamber 21 overflows the second fluid passage 60, the material enters the middle chamber 31, and the second porous medium 32 begins to absorb the material. When the liquid level of the material in the middle chamber 31 does not reach the position of the third liquid passage, since the upper part of the second porous medium 32 is in an unsaturated state, air can enter the inner chamber 21 and the outer chamber 11 through the third liquid passage, occupying the space where the material is lost, so that the air pressure between the chambers is balanced, and the material gradually soaks into the upper part of the second porous medium 32 by capillary action until the whole second porous medium 32 is in an absorption-saturated state, and the excess material begins to normally transfer to the atomization chamber 41.

[0044] In some embodiments, an atomization core 80 is disposed in the atomization chamber 41 of the atomizer. The atomization core 80 is fixed near the bottom of the atomization tube 40. The atomization core 80 receives the aerosol-forming matrix and atomizes it to form an aerosol for the user to inhale. The atomization core 80 is generally at approximately the same horizontal position as the fluid passage entering the atomization chamber 41 to facilitate the atomization core 80 to quickly receive the aerosol-forming matrix. Further, the second fluid passage 60 and the fourth fluid passage are on the same axis; or the projection of the second fluid passage 60 and the projection of the fourth fluid passage on the axis at least partially overlap; that is, the second fluid passage 60 and the fourth fluid passage are generally at approximately the same horizontal position to facilitate the atomization core 80 to quickly receive the aerosol-forming matrix.

[0045] In some embodiments, refer to Figure 3As shown by the arrow, when the material flows from the inner chamber 21 into the middle chamber 31, the material preferentially enters the middle chamber 31 from the second fluid channel 60 with a lower horizontal position. The third fluid channel 70 serves as a gas channel to balance the air pressure between the middle chamber 31 and the inner chamber 21. When the liquid level of the material in the middle chamber 31 starts to be higher than the position of the third fluid channel 70, the third fluid channel 70 can also serve as a flow channel for the material. Further, the flow area of the second fluid channel 60 is larger than that of the third fluid channel 70, so that the atomizer can accelerate the transfer of the material to the atomization chamber 41 when the atomization chamber 41 is in a negative pressure state.

[0046] In some embodiments, the first porous medium 22 and the second porous medium 32 are made of the same or different materials. Generally, cotton is used as the porous medium in the atomizer to absorb the aerosol generating matrix. Among them, the first porous medium 22 is arranged in the inner chamber 21 to absorb the material in the outer chamber 11, and the second porous medium 32 is arranged in the middle chamber 31 to absorb the material overflowing from the inner chamber 21.

[0047] In some embodiments, the density of the first porous medium 22 is 0.07 g / cm 3 .

[0048] In some embodiments, the unilateral interference amount between the first porous medium 22 and the inner chamber 21 is 0.25 mm, that is, the interference amount between the first porous medium 22 and the inner wall of the inner chamber 21 close to the middle chamber 31 is 0.25 mm, or the interference amount between the first porous medium 22 and the inner wall of the inner chamber 21 close to the outer chamber 11 is 0.25 mm. The assembly tightness between the first porous medium 22 and the inner chamber 21 can ensure smooth material transfer while also ensuring smooth air reflux between multiple chambers.

[0049] In some embodiments, the second porous medium 32 has a higher density than the first porous medium 22. For example, the density of the second porous medium 32 is 0.11 g / cm 3 . To better lock the material and reduce the material overflow speed.

[0050] In some embodiments, the unilateral interference amount between the second porous medium 32 and the middle chamber 31 is 0.25 mm, that is, the interference amount between the second porous medium 32 and the inner wall of the middle chamber 31 close to the atomization chamber 41 is 0.25 mm, or the interference amount between the second porous medium 32 and the inner wall of the middle chamber 31 close to the inner chamber 21 is 0.25 mm, which can ensure smooth material transfer while also ensuring smooth air reflux between multiple chambers.

[0051] The above are only partial or preferred embodiments of the present utility model. Neither the text nor the drawings can limit the scope of protection of the present utility model. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the overall concept of the present utility model, or any direct / indirect application in other related technical fields is included within the scope of protection of the present utility model.
