Description

Atomizer and electronic atomization device

Technical Field

The embodiment of the application relates to the technical field of electronic atomization, in particular to an atomizer and an electronic atomization device.

Background

Smoking articles (e.g., cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. Attempts have been made to replace these tobacco-burning products by making products that release compounds without burning.

An example of such a product is a heating device that releases a compound by heating rather than burning the material. For example, the material may be tobacco or other non-tobacco products, which may or may not include nicotine. As another example, there are aerosol-providing articles, e.g. so-called electronic nebulizing devices. These devices typically contain a vaporizable liquid that is heated to vaporize it, thereby generating an inhalable aerosol.

Known electronic atomization devices store and supply a liquid substrate through a reservoir chamber, and draw and deliver the liquid substrate to a heating element for thermal atomization by a wicking element. The negative pressure in the reservoir chamber will gradually increase as the liquid is consumed, making it difficult for the liquid substrate to be sucked and transferred by the drainage member.

In alternative implementations, the liquid-conducting element comprises flexible fibers, such as cotton fibers, non-woven fabrics, fiberglass strands, and the like, or comprises a porous material having a microporous structure, such as a porous ceramic; the heating element may be bonded to the wicking element by printing, deposition, sintering, or physical assembly, or may be wound around the wicking element.

Further in the preferred implementation shown in fig. 3-5, the atomizing assembly comprises: a liquid-guiding component 30 for sucking and transferring the liquid matrix, and a heating component 40 for heating and vaporizing the liquid matrix sucked by the liquid-guiding component 30. Specifically, the method comprises the following steps:

in the schematic cross-sectional structure shown in fig. 5, a flue gas conveying pipe 11 is arranged in the main housing 10 along the axial direction; a reservoir 12 for storing a liquid medium is also provided in the main housing 10. In practice, the flue gas conveying pipe 11 extends at least partially in the liquid storage chamber 12, and the liquid storage chamber 12 is formed by the space between the outer wall of the flue gas conveying pipe 11 and the inner wall of the main shell 10. The first end of the smoke transmission tube 11 opposite to the near end 110 is communicated with the suction nozzle opening a, and the second end of the smoke transmission tube opposite to the far end 120 is in airflow connection with the atomizing surface 310 of the liquid guiding element 30 and the atomizing chamber 340 defined between the end cap 20, so that the aerosol generated by the heating element 40 and released to the atomizing chamber 340 is transmitted to the suction nozzle opening a for smoking.

Referring to the configuration of the fluid directing element 30 shown in fig. 3, 4 and 5, the shape of the fluid directing element 30 is configured to be, in embodiments, a generally, but not limited to, a block-like configuration; according to a preferred design of this embodiment, it comprises an arched shape with an atomizing surface 310 facing the end cap 20 in the axial direction of the main housing 10; wherein, in use, the side of the liquid guiding element 30 facing away from the atomizing surface 310 is in fluid communication with the liquid storage cavity 12 to absorb the liquid substrate, and the microporous structure inside the liquid guiding element 30 conducts the liquid substrate to the atomizing surface 310 to be heated and atomized to form aerosol, and the aerosol is released or escapes from the atomizing surface 310.

Wherein:

in terms of specific structure and shape, the flexible second sealing element 50 is substantially in the shape of a hollow cylinder, the interior of the second sealing element is hollow for accommodating the liquid guiding element 30, and the second sealing element is sleeved outside the liquid guiding element 30 in a close fit manner.

Rigid carrier 60 retains the wicking element 30, which is sleeved with flexible second sealing element 50, and in some embodiments may comprise a generally annular shape with an open lower end, and a retaining space 64 for receiving and retaining flexible second sealing element 50 and wicking element 30. The flexible second sealing element 50 can seal the gap between the liquid guide element 30 and the bracket 60 on the one hand, and prevent the liquid matrix from seeping out of the gap between the liquid guide element and the bracket; on the other hand, the flexible second sealing element 50 is located between the drainage element 30 and the holder 60, which is advantageous for the drainage element 30 to be stably accommodated in the holder 60 without being loosened.

A first flexible sealing member 70 is provided between the reservoir 12 and the support frame 60 and has a profile adapted to the cross-section of the internal profile of the main housing 10 to seal the reservoir 12 against leakage of the liquid substrate from the reservoir 12. Further to prevent the shrinkage deformation of the first sealing element 70 of flexible material from affecting the tightness of the seal, support is provided for the flexible first sealing element 70 by the above bracket 60 being received therein.

After the installation, in order to ensure the smooth transfer of the liquid substrate and the output of the aerosol, the flexible first sealing element 70 is provided with a first liquid guide hole 71 for the liquid substrate to flow through, the bracket 60 is correspondingly provided with a second liquid guide hole 61, and the flexible second sealing element 50 is provided with a third liquid guide hole 51. In use, the liquid medium in the liquid storage chamber 12 flows to the liquid guiding element 30 retained in the flexible second sealing element 50 through the first liquid guiding hole 71, the second liquid guiding hole 61 and the third liquid guiding hole 51 in sequence, as shown by an arrow R1 in fig. 4 and 5, and then is absorbed and transferred to the atomizing surface 310 for vaporization, and the generated aerosol is released into the atomizing chamber 340 defined between the atomizing surface 310 and the end cap 20.

In the aerosol output path during the suction process, referring to fig. 3 and 4, the first flexible sealing element 70 is provided with a first insertion hole 72 for inserting the lower end of the smoke transport pipe 11, the corresponding support 60 is provided with a second insertion hole 62, and the support 60 is provided with an aerosol output channel 63 for connecting the atomizing surface 310 with the second insertion hole 62 in an airflow manner at the side opposite to the main housing 10. After installation, the complete suction airflow path is shown by an arrow R2 in fig. 3, the external air enters into the atomizing chamber 340 through the first air inlet 23 on the end cap 20, and then the generated aerosol is carried to the second jack 62 through the aerosol output channel 63, and then is output to the smoke transmission tube 11 through the first jack 72.

With further reference to fig. 3 to 6, a silica gel receptacle 90 is further disposed between the end cap 20 and the atomizing surface 310 of the liquid guiding element 30, and an atomizing chamber 340 for containing aerosol is defined between the silica gel receptacle 90 and the atomizing surface 310; the silicone receptacle 90 is on the other hand used to receive aerosol condensate in the nebulization chamber 340 or liquid that has seeped out of the nebulization surface 310 of the liquid-conducting element 30. Of course, referring to fig. 9, the silicone bearing seat 90 is provided with an air hole 92 opposite to the first air inlet 23 for allowing the external air entering from the first air inlet 23 to enter the atomizing chamber 340. Meanwhile, the silicone socket 90 is further provided with an electrode hole 91 for the second electrical contact 21 to penetrate and then to be abutted against the heating element 40.

With further reference to figures 7 and 8, the bracket 60 is provided with a longitudinally extending air passage 65, the air passage 65 being adapted, in use, to supply air to the reservoir 12 to relieve the negative pressure in the reservoir 12 when the negative pressure in the reservoir 12 increases to a threshold level. Specifically, the upper end of the air channel 65 in fig. 8 is the air outlet end, which is directed toward the reservoir 12. The holder 60 is provided with a holding groove 66 adjacent to the air inlet end of the air passage 65 for fitting and holding the porous body 80. When assembled, the porous body 80 can shield or cover the air intake end of the lower end of the air passage 65.

The porous body 80 is made of porous cotton, fiber cotton, sponge, rigid foam metal, porous ceramic body, or the like; the porous body 80 is in air flow communication with the nebulizing chamber 340 through a groove on the surface of the holder 60 or a gap between the holder 60 and the main housing 10. Further, in use, air in the gap between the holder 60 and the main casing 10, or air in the atomization chamber 340 can enter the air passage 65 through the pores of the porous body 80. In the preferred embodiment shown in fig. 7 and 8, the porous body 80 is preferably made of porous cellucotton, and is shaped in a regular block shape, which is advantageous for assembly.

In the implementation of the viewing angle shown in fig. 8, it is preferable that the block-shaped porous body 80 has a length of about 5.5mm, a width of 1.6mm, and a height of about 2.2 mm.

As further shown in fig. 9 to 11, the first sealing member 70 is provided with a shielding portion 73 for shielding or sealing the air outlet end of the air passage 65; when the shield portion 73 is suspended relative to the remainder of the first seal member 70, it may flex or deform or oscillate during use. When the negative pressure in the reservoir 12 increases to exceed the threshold value, the pressure difference between the upper and lower sides of the shielding portion 73 in fig. 11 drives the shielding portion 73 to bend or deform toward the reservoir 12, and further opens the air outlet end of the air channel 65, so that the external air passes through the porous body 80 and the air channel 65 in sequence as shown by an arrow R3 in fig. 11 and enters the reservoir 12 to relieve the negative pressure in the reservoir 12. The air inlet end of the air channel 65 is shielded or covered by the porous body 80, the porous structure in the porous body 80 can allow air to pass through the air channel 65, and the liquid is prevented from leaking through the porous body 80.

As further shown in fig. 10, the shielding portion 73 is formed by a U-shaped slot or slit 74, whereby the shielding portion 73 is suspended from the rest of the sealing member 80. And, the bending direction of the U-shaped groove or slit 74 is toward the center of the first sealing member 70; when the first sealing member 70 is fitted into the main casing 10 upward from the open end of the main casing 10 during the fitting process, and the width edge of the first sealing member 70 rubs against the inner wall of the main casing 10, the shielding portion 73, which is substantially isolated from the width edge of the first sealing member 70, does not bend or tilt as the edge portion rubs against the inner wall of the main casing 10; the shield portion 73 remains substantially flush or sealed against the air outlet end of the air channel 65 after assembly.

With further reference to the embodiment shown in fig. 10, the shielding portion 73 is configured to extend in the width direction of the first sealing member 70; of course, in a variable implementation, there may be some oblique angle to the width direction. The angle of the preferable implementation included angle can be between-90 degrees and 90 degrees.

According to the illustration, the air channel 65 is in the form of a through hole; due to the above structure, the aperture of the through hole of the air channel 65 can be controlled to be 0.5-2 mm.

Fig. 12 and 13 show schematic structural views of a first sealing element 70a of a further variant embodiment; the position of the air channel 65 is a relief hole 73a, and the air outlet end of the air channel 65 is exposed in the liquid storage cavity 12 through the relief hole 73a after assembly to be in an exposed state. The air passageway 65 is able to replenish air in use in response to a change in negative pressure within the reservoir 12 more quickly.

The above porous body 80 blocks the air intake end of the air passage 65, which is advantageous for assembly and retention compared to the manner in which the porous body 80 is filled into the air passage 65.

While the above air passage 65 is in the form of a through hole provided in the holder 60, in other variant implementations, the air passage 65 may also be in the form of a groove formed on an opposing surface of either the holder 60 or the first sealing member 70. For example, the air passage 65 is formed by a groove provided on the surface of the bracket 60 surrounded by the first sealing member 70.
