Description

Atomizer and electronic atomization device

Technical Field

The embodiment of the application relates to the field of electronic atomization devices, 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 vapor or aerosol. The known electronic atomization device generally sucks liquid matrix from a liquid absorption element step by step and transfers the liquid matrix to a heating element to be vaporized to generate aerosol, and the aerosol is output to the outside of the device by a smoke output channel to be sucked; in use of the above known electronic atomising devices there is a risk that the liquid matrix seeps from the gap between the wicking element and the other components to the smoke output channel.

and an atomizing assembly 30 for drawing the liquid substrate from the reservoir 12 by capillary infiltration and for heating and vaporizing the drawn liquid substrate to generate an aerosol for inhalation. Specifically, the atomizing assembly 30 includes a wicking element 31, and a heating element 32 at least partially surrounding the wicking element 31. Referring to fig. 3 and 4, the wicking member 31 is configured to extend across the width of the main housing 10 and is exposed at both ends or in fluid communication with the reservoir 12, and the liquid matrix within the reservoir 12 is absorbed by both ends of the wicking member 31 as indicated by arrows R1 in fig. 3 and then transferred inwardly. The heating element 32 surrounds or wraps at least a portion of the wicking element 31 for heating at least a portion of the liquid substrate within the first wicking element 31 to generate an aerosol for inhalation.

In alternative implementations, the liquid absorbent member 31 can be or include a porous ceramic body, a fibrous web, a porous material, or the like; the heating element 32 may be a resistive metallic material such as iron, nickel, chromium, alloys thereof, or the like.

As further shown in fig. 3-5, to facilitate assembly and securement of the atomization assembly 30 within the main housing 10, a rigid support frame 50 and a flexible sealing member 40 are also provided within the main housing 10, and the atomization assembly 30 is held and retained by the support frame 50 and the sealing member 40 together. As shown in fig. 5 in particular, the rigid support frame 50 is provided with a first wall 510 and a second wall 520 extending in the length direction, and the first wall 510 and the second wall 520 are respectively disposed opposite to each other near both sides of the main housing 10 in the thickness direction, and an atomizing chamber 530 and a support groove 540 are formed between the first wall 510 and the second wall 520 and are used for supporting the liquid absorbing member 31 at both ends of the first wall 510 and the second wall 520. The support slot 540 is generally U-shaped, as shown in fig. 5.

After being installed, the liquid absorbing element 31 and the heating element 32 are both mainly contained in the atomizing chamber 530 so as to release the generated aerosol to the atomizing chamber 530, and the aerosol is output from the atomizing chamber 530 to the smoke output pipe 11 through the air pipe insertion hole 41 on the sealing element 40.

The heating element 32 is also powered at both ends by an elongated pin or wire 321 and a second electrical contact 21 and thus the heating element 32 through the second electrical contact 21.

The sealing member 40 further wraps around the first wall 510 and the second wall 520 of the holding frame 50, and the sealing member 40 grips or presses the liquid absorbing member 31 from above in fig. 5 after assembly, so that the atomizing assembly 30 is stably held between the sealing member 40 and the holding frame 50.

In use, the sealing member 40 serves to prevent the liquid medium in the reservoir 12 and hence the flue gas output tube 11 and the nebulizing chamber 530, so that the liquid medium can only leave the reservoir 12 by being sucked by the first liquid suction member 31.

As further shown in fig. 5, sealing member 40 is provided with perforations 42 on both sides in the width direction to allow wicking element 31 to extend at least partially through the perforations into reservoir 12 after holding or compressing wicking element 31.

With further reference to fig. 6, the sealing member 40 is constructed to include a retaining portion 43 extending toward the wicking element 31 and to be retained on the support frame 50 by the retaining portion 43 in a manner to sandwich or compress the wicking element 31.

The inner wall of the sealing element 40 close to the nebulizing chamber 530 is also provided with an extended lip 44 around the air duct insertion opening 41, which lip 44 forms, with the grip portion 43, a barb or a grooved space 45 facing away from the flue gas outlet duct 11. When atomizer 100 is in use, either flat or inverted in the opposite direction as in fig. 3, liquid matrix in reservoir 12, after seepage into atomizing chamber 530 through the gap between retaining portion 43 and liquid absorbing member 31 as indicated by arrow R3 in fig. 6, can be stopped by lip 44 and retained in barb or channel-shaped space 45 formed between lip 44 and retaining portion 43. Thereby preventing the liquid medium from flowing directly into the tracheal hole 41, resulting in problems with aspiration by the user during aspiration.

With further reference to fig. 6, the stepped outer surface of the ledge 44 opposite the gripping portion 43 is designed to direct the liquid substrate that resides in the barb or channel shaped space 45 to drip onto the atomizing assembly 30 for re-vaporization when the atomizer 100 is converted from a flat or inverted configuration to the aspirating or holding configuration of fig. 3. Or in other variant implementations, the outer surface of the ledge 44 opposite the clamping portion 43 is of inclined design, such as inclined flat, curved, etc.

The rigid support 40a is covered with a sealing member 60a at least partially on the surface thereof, thereby sealing the gap between the rigid support 40a and the main housing 10a to prevent the liquid medium in the reservoir chamber 12a from leaking out of the gap.

In order to cooperate with the liquid guiding and assembling of the rigid support 40a, the sealing element 60a is provided with a first liquid guiding hole 62a for allowing the liquid substrate to flow to the rigid support 40a, and a second insertion hole 61a for inserting the flue gas output pipe 11a into the first insertion hole 41a after penetrating through the same. Meanwhile, the sealing element 60a also seals the gap between the rigid support 40a and the first insertion hole 41a, so as to prevent the liquid medium in the liquid storage cavity 12a from extending into the flue gas output pipe 11a from the gap.

As shown by an arrow R1 in fig. 7, the rigid support 40a is further provided with a second liquid guiding hole 42a, and in use, the liquid substrate in the liquid storage chamber 12a is transferred to the atomizing assembly 30a through the first liquid guiding hole 62a and the second liquid guiding hole 42a in sequence to be absorbed and vaporized.

Meanwhile, the holding space 45a is in air flow communication with the plurality of capillary grooves 43a on the outer wall of the rigid support 40a, and thus the condensate or liquid or the like in the holding space 45a can be conducted or adsorbed to the capillary grooves 43a by capillary adsorption, thereby preventing seepage from the end cap 20 a. As can be seen in particular in fig. 10, the holding space 45a is in air-flow communication with the capillary groove 43a through windows 48a on both sides of the rigid support 40 a.

In other variations, the retaining portion 46a may be U-shaped to further conform to the shape of the atomizing assembly 30a, which may help reduce the gap between the atomizing assembly 30a and prevent the liquid matrix from seeping out.

Also in the preferred embodiment shown in fig. 9, the flexible support seat 50a defines the inner wall of the atomizing chamber 70a, and is also formed with a groove 53a extending in the longitudinal direction; the function and purpose of this groove 53a is essentially to adsorb or retain the condensate of the aerosol generated and accumulated in the nebulization chamber 70a, preventing it from flowing out of the air intake channel 52 a.
