Description

Electron smog spinning disk atomiser and electron cigarette

Technical Field

The embodiment of the application relates to electron cigarette technical field, especially relates to an electron smog spinning disk atomiser and electron cigarette.

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 e-vapor devices. These devices typically contain a liquid that is heated to vaporize it, thereby generating an inhalable vapor or aerosol. The liquid may comprise nicotine and/or a fragrance and/or an aerosol generating substance. As a known electronic cigarette, the' 201810150690.7 patent employs a block-shaped porous ceramic body having grooves on an upper surface thereof as a medium for liquid substrate transfer, and provides a heating element on a lower surface opposite the grooves for heating liquid substrate absorbed by the porous ceramic body, thereby generating an aerosol for inhalation. The known electronic cigarette device matched with the assembly of the porous ceramic body needs to adopt the rigid supporting element to accommodate and maintain the porous ceramic body and then coat the silica gel sealing element to be integrally assembled in the electronic cigarette tool, so that more parts are relatively inconvenient to assemble.

The interior of the main housing 10 is provided with a retaining groove 18 near the lower end thereof in a correspondingly mating configuration, and further in the preferred embodiment shown in fig. 7, the retaining groove 18 may be formed by a portion of the structure separating or defining the lower end of the partition wall 12 of the reservoir 13 and the second airflow passageway 14.

The holding groove 18 has a shape open at the lower end, and forms a holding space for accommodating and holding the porous body 41 together with the first cavity 310 of the end cap 30.

Further to assist in sealing the reservoir 13 and the atomizing assembly 40, a sealing member 80 made of a flexible material such as silicone is disposed between the main housing 10 and the end cap 30, and the sealing member 80 generally includes two parts:

a vertical portion 81 extending in the length direction of the main casing 10 in fig. 8, and a horizontal portion 82 perpendicular to the vertical portion 81; in use, the vertical portion 81 is annular in shape, and is further wrapped outside the porous body 41 in the circumferential direction of the porous body 41.

In a specific configuration, the vertical portion 81 has a shape having a holding space penetrating in the thickness direction, so that the porous body 41 is wrapped by the vertical portion 81 by being accommodated and held in the holding space in practice.

Further, in the sealing member 80 having the above configuration, the vertical portion 81 thereof is formed to penetrate in the thickness direction to form the accommodating and holding space, so that the porous body 41 is wrapped and then corresponds to the configuration of being open or opened in the thickness direction, and thus the liquid absorbing surface 410 and the atomizing surface 420 on both sides of the porous body 41 can be ensured to be exposed, so that the liquid absorbing surface 410 of the porous body 41 is kept in liquid communication with the liquid storage chamber 13, and the atomizing surface 420 is kept in air flow communication with the second air flow channel 14.

In use, the above vertical portion 81 is formed between the holding space surrounded by the holding groove 18 and the first cavity 310 and the porous body 41 for sealing the gap between the holding groove 18 and/or the first cavity 310 and the porous body 31.

While the horizontal portion 82 is opposite the reservoir 13 in assembly and serves to seal the lower end of the reservoir 13. Also, the horizontal portion 82 is opposite the second cavity 320 of the end cap 30 and is received and retained by the second cavity 320 of the end cap 30.

Further to facilitate assembly of the end cap 30 to the seal element 80, a detent 83 is provided on the seal element 80 opposite and in register with the tab 34 of the end cap 30, the tab 34 being aligned with and extending lengthwise into the detent 83 during assembly, to facilitate positioning of the seal element 80 for installation, while also providing rigid support for various portions of the seal element 80.

According to a preferred embodiment shown in fig. 8, the vertical portion 81 of the sealing member 80 is located off-center from the sealing member 80, which facilitates the liquid matrix of the reservoir 13.

In the preferred embodiment shown in fig. 7, the configuration of the partition wall 12 includes:

the partition portion 121, which extends in the longitudinal direction, mainly partitions the inner space of the main housing 10 around the reservoir chamber 13 and the second air flow path 14.

A holding portion 122 extending in the width direction, the holding portion 122 being formed mainly by the user as the above holding groove 18 for forming a holding space in cooperation with the end cap 30 to receive and hold the atomizing assembly 40. Wherein the vertical portion 81 of the sealing member 80 is located primarily between the retaining portion 122 and the atomizing assembly 40.

At least one convex plate 123 extending from the partition portion 121 toward the interior of the reservoir 13 along the thickness direction, the convex plate 123 and the retaining portion 122 surrounding the retaining groove 18 are abutted or connected, so as to serve as a reinforcing structure to improve the strength, so that the retaining portion 122 made of plastic material is not bent or deformed outwards when the sealing element 80 is tightly abutted, thereby preventing the sealing effect from being affected by the reduction of the fit tightness between the sealing element 80 and the retaining portion 122.

According to a preferred embodiment shown in fig. 7, the retaining portion 122 is offset with respect to the dividing portion 121.

As further shown in fig. 6, the air inlet holes 32 of the end cap 30 are obliquely disposed and the air outlet ports of the air inlet holes 32 are directed toward the atomizing surface 420 or the heating element 42, so that the incoming air can carry away as much aerosol escaping from the atomizing surface 420 as possible.

Referring further to fig. 5 and 9, the cross-section of the intake holes 32 is in the shape of an elongated strip extending in the width direction.

Further in the implementation shown in FIG. 10, the first magnetic element 171a and the fourth magnetic element 282a are made of soft magnetic material, such as iron, cobalt, nickel, etc.

The second magnetic element 172a and the third magnetic element 281a are made of permanent magnetic material, such as common magnet, ru fe boron, etc. In addition, the second magnetic element 172a and the third magnetic element 281a have opposite magnetic pole directions during the setting, for example, in fig. 10, the upper end of the second magnetic element 172a is an N pole, the lower end is an S pole, the upper end of the third magnetic element 281a is an S pole, and the lower end is an N pole. It is advantageous that, during use, the atomizer 100a can only be received into the receiving chamber 270a in the specific orientation shown in fig. 10, while the second magnetic elements 172a and the third magnetic elements 281a are mutually repelled when the atomizer 100a is rotated 180 degrees to the opposite state as in fig. 10.
