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 aerosol.

Known electronic atomisation devices typically generate an aerosol by heating a liquid substrate drawn by capillary wetting by a wicking element by a heating element incorporated in the wicking element; when the electronic atomization device is used, the liquid substrate in the contact area of the liquid absorption element and the heating element has higher temperature and is vaporized smoothly; the part of the liquid absorbing element far away from the heating element has low temperature and large liquid base mass, the vaporization is not enough to form aerosol liquid drops with large particle size and generate nourishing sound (commonly called 'frying oil'), the generated aerosol containing the large liquid drops is directly output by the smoke output channel, and the suction experience is reduced.

As further shown in fig. 2, the second electrical contact 21 of the atomizer 100 extends from the distal end 120 to the interior and is at least partially exposed at the surface of the end cap 50, thereby facilitating electrical conduction with the power mechanism 200 during use. Meanwhile, the distal end 120 of the nebulizer 100 is also provided with an air inlet 22 for external air to enter the nebulizer 100 during user inhalation.

Meanwhile, the atomizer 100 is further provided with a magnetic attraction element 23 penetrating from the distal end 120 to the inside, so that the atomizer 100 is stably held in the power supply mechanism 200 by magnetic attraction with the power supply mechanism 200 in use.

Further fig. 3 to 5 show an internal structural view and an exploded view of a part of the components of the atomizer 100 of fig. 2. According to what is shown in fig. 3 and 4, the nebulizer 100 further comprises:

the smoke output pipe 11 extends along the axial direction of the main shell 10, the upper end of the smoke output pipe is in airflow communication with the suction nozzle opening A positioned at the upper end of the main shell 100, and aerosol generated in the atomizer 100 is output to the suction nozzle opening A for suction;

a liquid storage cavity 12 formed by the space between the flue gas output pipe 11 and the inner wall of the main shell 10 and used for storing liquid matrix;

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 batt, a fibrous strand, 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.

Referring further to fig. 3-5, the atomizing assembly 30 is assembled and secured within the main housing 10 by the end cap 50 and the flexible sealing member 40. The atomization assembly 30 is collectively retained and held by the end cap 50 and the sealing member 40 after assembly. Referring specifically to fig. 5, the rigid end cap 50 is provided with a first wall 510 and a second wall 520 extending in the longitudinal 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 end cap 50, and when assembled, the sealing member 40 grips or presses the wicking element 31 from above in fig. 5, thereby stably holding the atomizing assembly 30 between the sealing member 40 and the end cap 50.

In alternative implementations, the sealing element 40 is generally made of a flexible material, such as silicone, rubber, etc. And is provided with an air pipe insertion hole 41, the lower end of the smoke output pipe 11 is inserted in the air pipe insertion hole 41 during assembly so as to be communicated with the atomizing chamber 530, thereby outputting the aerosol in the atomizing chamber 530 to the suction nozzle opening A for suction. 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 either side of the width thereof, such that, upon clamping or compressing the wicking element 31, the wicking element 31 can extend at least partially through the perforations 42 into or exposed from reservoir 12, and thereby be in fluid communication with reservoir 12.

Further to the airflow design of electronic aerosolizer 100, see fig. 3 and 4; the end cover 50 is provided with a main air chamber 51 and buffer air chambers 52 which are positioned on both sides of the main air chamber 51 in the width direction and communicate with the main air chamber 51; the buffer air chamber 52 is in direct air flow communication with the air inlet 22, so that during suction, the external air enters the buffer air chamber 52 from the air inlet 22, enters the main air chamber 51 from the buffer air chamber 52, and finally passes through the atomizing chamber 530 and is output to the flue gas output pipe 11 from the air outlet 511 between the main air chamber 51 and the atomizing chamber 530, and a complete suction air flow is formed as shown by an arrow R2 in fig. 3.

As further shown in fig. 6, the sealing member 40 includes a retaining portion 43 that extends toward the wicking element 31 and is held in a clamping or pressing manner on the end cap 50 by the retaining portion 43 of the wicking element 31.

Referring to fig. 6 to 8, the sealing member 40 is further provided with a shielding portion 44 between the atomizing unit 30 and the air pipe insertion hole 41, and the shielding portion 44 is mainly used for blocking large droplets generated by the frying oil in a non-central high-temperature region of the liquid absorbing member 31 from entering the air pipe insertion hole 41. The shielding portion 44 has a U-shaped side opening 441 toward one side in the thickness direction, the U-shaped side opening 441 being located at a central portion in the width direction for supplying aerosol to the flue gas outlet passage 11. As shown in fig. 7, the shielding portion 44 is open on one side in the thickness direction and closed on the other side, and the smoke output can be assisted to be advantageous for reducing the large suction resistance caused by the airflow outputted from the small-sized side opening 441.

As further shown in fig. 7, the shielding portion 44 is further provided with a convex edge 442 surrounding the U-shaped side opening 441, and the convex edge 442 forms a blocking structure similar to a barb to block liquid drops from flowing along the surface of the shielding portion 44 to the U-shaped side opening 441.

Referring to fig. 8 and 5, in the detailed design of the product, the edge of the open side of the shielding portion 44 is just aligned with the edge of the liquid absorbing member 31, and the shielding portion 44 is completely covered over the liquid absorbing member 31 in the thickness direction in the orthographic projection shown in fig. 8 after assembly. And in the design of dimensions; the tracheal insertion hole 41 is oval in shape, having a length d1 of 6.8mm and a width d1 of 4.2 mm. The extension of the heating element 32 of the helical coil is designed to be slightly less than the length of the tracheal insertion hole, 6.5 mm.

As shown in FIG. 8, the length d3 of shield portion 44 is 7.5mm, slightly greater than the length d1 of trachea cannula 41, and substantially completely covers the length of heating element 32. The width d4 of the U-shaped side opening 441 is 2.2mm in size and the extension d5 is 3.4 mm.

In fig. 8, the distance d6 is maintained between the outer edge of the upper side of the shielding part 44 and the trachea insertion hole 41, but the trachea insertion hole 41 is not completely covered, and the distance d6 is 1 mm.

With the above size design, only the part of the shielding part 44 with the U-shaped side opening 441 located at the central position is exposed out of the heating element 32, and the other parts are covered with the heating element 32; the U-shaped side opening 441 exposes the heating element 32 to a length of 2.2mm, which is 1/3 times the length of the heating element 32, regardless of manufacturing and assembly tolerances, and is at least 1/2 times less than the length of the heating element 32. The large droplets formed by the frying oil can be blocked as much as possible on the area where the high temperature is not concentrated.

Meanwhile, the distance d6 between the outer edge of the upper side of the shielding part 44 and the trachea insertion hole 41 ensures that the shielding part 44 does not completely cover the trachea insertion hole 41, and the distance d6 and the U-shaped side opening 441 jointly expose 1/3 of the trachea insertion hole 41, which is larger than the area of the trachea insertion hole 41, and is close to 1/2, so that proper suction resistance is ensured.
