Description

A sealing element and electron smog spinning disk atomiser for electron smog spinning disk atomiser

The present invention is based on the divisional application of patent No. 202021116012.8.

Technical Field

The embodiment of the utility model relates to the technical field of electronic cigarettes, in particular to an electronic cigarette atomizer and an electronic cigarette.

Background

Aerosol-providing articles, such as so-called e-cigarette devices, exist. These devices typically contain tobacco tar that is heated to atomize it, thereby generating an inhalable vapor or aerosol. The tobacco tar may comprise nicotine and/or a fragrance and/or an aerosol generating substance (e.g. glycerol). In addition to the flavoring in the tobacco tar.

Known electronic cigarette devices generally include a porous ceramic body having a large number of micropores therein for sucking and conducting the above-mentioned tobacco tar, and a heating element is provided on one surface of the porous ceramic body to heat-atomize the sucked tobacco tar. The micropore in the porous body is used as a channel for smoke to infiltrate and flow to the atomizing surface on one hand, and is used as an air exchange channel for supplying air to enter the oil storage cavity from the outside after smoke in the oil storage cavity is consumed to maintain air pressure balance in the oil storage cavity on the other hand, so that bubbles can be generated in the porous ceramic body when the smoke is heated, atomized and consumed, and then the bubbles enter the oil storage cavity after emerging from the oil absorption surface.

To above known electron cigarette device, when the tobacco tar along with inside stock solution chamber consumes, become negative pressure state in the stock solution intracavity gradually to prevent to a certain extent that the fluid transfer makes the tobacco tar reduce to transmit to the vaporization on the atomizing surface through the micropore passageway of porous ceramic body. In particular, in the known electronic cigarette device, in a continuous suction use state, air outside the liquid storage cavity is difficult to enter the liquid storage cavity through the micropore channels of the porous ceramic body in a short time, so that the transfer rate of the tobacco tar to the atomizing surface is slowed, and insufficient tobacco tar supplied to the heating element can cause the temperature of the heating element to be too high, so that the tobacco tar components are decomposed and volatilized to generate harmful substances such as formaldehyde.

The embodiment of the utility model provides an electronic cigarette product of a type for heating and atomizing a liquid matrix. In one embodiment, illustrated by way of example in the general case of the flat cigarette of figures 1 and 2, includes an atomizer 100 for atomizing a liquid substrate, and a power supply device 200 for powering the atomizer 100. Wherein, the power supply device 200 is further provided with conductive elastic needles 210 for correspondingly connecting and conducting with the atomizer 100; and a magnet 220 magnetically attracted in correspondence with the magnetically attracted element on the nebulizer 100.

The detailed structure of the atomizer 100 can be seen in the exploded schematic views of fig. 3 and 4 and the cross-sectional schematic view of fig. 5, and includes:

a hollow cylindrical outer housing 10, the outer housing 10 having proximal and distal ends opposite in an axial direction; wherein, according to the requirement of common use, the proximal end is configured as one end of the aerosol sucked by the user, and a suction nozzle A used for sucking by the user is arranged at the proximal end; the distal end is used as one end for assembling and connecting with the power supply device 200, and the distal end of the outer casing 10 is open, and a detachable end cap 20 is installed on the open end, so that the opening is conveniently opened to install various functional components inside the outer casing 10.

As further shown in fig. 3 to 5, the interior of the outer housing 10 is provided with a liquid storage chamber 12 for storing the liquid matrix, a porous body 30 for sucking the liquid matrix from the liquid storage chamber 12, and a heating element 40 for heating and vaporizing the liquid matrix sucked by the porous body 30; specifically, in the schematic cross-sectional structure shown in fig. 5, a smoke transport pipe 11 is axially arranged in the outer shell 10, and a liquid storage cavity 12 for storing liquid matrix is formed in a space between an outer wall of the smoke transport pipe 11 and an inner wall of the outer shell 10; the first end of the relatively near end of the smoke conveying pipe 11 is communicated with the smoking opening A, and the relatively far end is connected with the aerosol airflow generated by heating of the heating element 40, so that the aerosol generated by the liquid substrate vaporized by the heating element 40 is conveyed to the smoking opening A for smoking.

Referring to the structure of the porous body 30 shown in fig. 3 to 5, the shape of the porous body 30 is configured to be, in embodiments, a substantially, but not limited to, a block-like structure; according to a preferred design of the present embodiment, it comprises an arched shape having a liquid-absorbing surface 31 and an atomizing surface 32 which are opposite in the axial direction of the outer housing 10, i.e., upper and lower surfaces which are the base portions of the block-shaped porous body 30 in fig. 3; wherein the liquid absorbing surface 31 is opposite to the liquid storage cavity 12 and is contacted with the liquid matrix in the liquid storage cavity 12 directly or indirectly so as to absorb the liquid matrix; the porous body 30 has a microporous structure for conducting the liquid substrate to the atomizing surface 32, and the liquid substrate is heated and atomized to form aerosol, and the aerosol is released or escaped from the atomizing surface 32. In the structure of the porous body 30 shown in fig. 5, since the liquid absorption surface 31 and the atomization surface 32 are parallel to each other, the moving directions of the liquid matrix and the aerosol in the porous body 30 are perpendicular to the plane of the atomization surface 32. The movement of the aerosol and liquid matrix within the porous body 30 is smoother and more convenient to manufacture.

Further to facilitate assembly and fixation, the porous body 30 in the preferred embodiment shown in fig. 3-5 also includes a support portion 33.

In some embodiments, the porous body 30 may be made of a hard capillary structure of porous ceramic, porous glass, or the like. The heating element 40 is preferably formed on the atomization surface 32 by mixing conductive raw material powder and printing aid into a slurry and then sintering the slurry after printing, so that all or most of the surface of the heating element is tightly combined with the atomization surface 32, and the heating element has the effects of high atomization efficiency, low heat loss, dry burning prevention or great reduction of dry burning and the like. The heating element 40 may be made of stainless steel, nichrome, ferrochromium alloy, titanium metal, etc. in some embodiments.

With further reference to fig. 3 to 5, in order to assist the installation and fixation of the porous body 30 and the sealing of the liquid storage cavity 12, a sealing mechanism is further provided in the outer housing 10, and the sealing mechanism includes a flexible silicone sleeve 50, a rigid support frame 60 and a flexible silicone seat 70, which not only seals the opening of the liquid storage cavity 12, but also fixedly holds the porous body 30 therein. Wherein the content of the first and second substances,

in the specific structure and shape, the flexible silicone sleeve 50 is substantially annular, is hollow inside and is used for accommodating the porous body 30, and is sleeved outside the porous body 30 in a flexible tight-fitting manner.

The rigid support frame 60 holds the porous body 30 sleeved with the flexible silicone sleeve 50, and in some embodiments, may have a ring shape with an open lower end, and an inner space is used for accommodating and holding the flexible silicone sleeve 50 and the porous body 30.

The flexible silicone seat 70 is disposed at the distal end of the reservoir 12 and has a shape adapted to the cross-section of the inner contour of the outer housing 10, thereby sealing the reservoir 12 and preventing the liquid medium from leaking out of the reservoir 12. Further, in order to prevent the shrinkage deformation of the flexible silicone seat 53 made of flexible material from affecting the tightness of the seal, the rigid support bracket 60 is accommodated in the flexible silicone seat 70 to support the same.

After the installation, in order to ensure the smooth transfer of the liquid matrix and the output of the aerosol, the flexible silica gel seat 70 is provided with a first liquid guide channel 71 for the liquid matrix to flow through, the rigid support frame 60 is correspondingly provided with a second liquid guide channel 61, and the flexible silica gel sleeve 50 is provided with a third liquid guide channel 51. In use, the liquid matrix flows through the first liquid guiding channel 71, the second liquid guiding channel 61 and the third liquid guiding channel 51 in sequence to the liquid absorbing surface 31 of the porous body 30 held in the flexible silicone sleeve 50, as shown by an arrow R1 in fig. 5, and is absorbed and then transferred to the atomizing surface 32 to be vaporized.

In the aerosol output structure during the pumping process, the flexible silica gel seat 70 is provided with a first insertion hole 72 for inserting the lower end of the flue gas transmission pipe 11, the rigid support frame 60 is correspondingly provided with a second insertion hole 62, and the rigid support frame 60 is provided with a first air flow channel 64 for communicating the atomization surface 32 with the second insertion hole 62 in an air flow manner at the side opposite to one side wall of the outer shell 10. After installation, referring to arrow R2 in fig. 6, the aerosol generated by the heating element 40 flows through the first airflow channel 64 to the second jack 62, and then is output to the smoke transmission tube 11 through the first jack 72.

Further in the auxiliary power supply and mounting structure, as shown in fig. 3 to 6, the end cap 20 is provided with a first support leg 21 for supporting and fixing the sealing mechanism, which is of course supported by abutting against the lower end surface of the rigid support frame 60 in the implementation. The end cover 20 is further provided with a first mounting hole 22 and a second mounting hole 23; the first mounting hole 22 is used for mounting a magnetic element 25 which is magnetically attracted to the magnet 220 on the power supply device 200, the second mounting hole 23 is used for mounting an electrode 26, and the electrode 26 passes through the second mounting hole 23 and abuts against two ends of the heating element 40 so as to supply power to the heating element 40; of course, after the atomizer 100 is connected to the power supply device 200, the electrode 26 is electrically connected to the corresponding conductive pogo pin 210 on the power supply device 200. At the same time, an air inlet 24 is provided in the end cap 20 for the external air to enter the atomizer 100 during the suction process, as indicated by the arrow R2 in fig. 6, and the external air flows through the air inlet 24 to the atomizing surface 32 and carries the aerosol output.

In the embodiment, a certain distance is kept between the atomizing surface 32 and the end cap 20, so that an atomizing chamber for the aerosol to escape is at least partially surrounded by the atomizing surface 32 and the end cap 20, and is of course in air flow communication with the air inlet hole 24 on the end cap 20 on one hand for the external air to enter into the atomizing chamber; and on the other hand is in gas flow communication with the flue gas duct 11 for the output of the aerosol generated and escaping from the atomising surface 32.

After the liquid medium in the liquid storage chamber 12 is vacuumed under negative pressure with consumption of the liquid medium, an air passage is further provided in the atomizer 100 to ensure that the liquid medium can be smoothly absorbed by the porous body 30. As further shown in fig. 7-9; the rigid support frame 60 is provided with a through hole 63 penetrating along the axial direction of the atomizer 100, and the through hole 63 forms the air channel for supplementing external air into the liquid storage cavity 12; the upper end of the through hole 63 is shielded by the first shielding portion 73 of the flexible silicone seat 70 after installation, the lower end is exposed without shielding, and the lower end is in airflow communication with the nebulizing chamber through a gap or a provided passage with the end cap 20.

The thickness and location of the first shielding portion 73 are further designed to be approximately in the relatively thin thickness dimension of 0.2mm to 0.5mm, and in more implementations, the first shielding portion 73 has a thinner thickness than other portions, so that the first shielding portion 73 is more easily deformed. The hardness of the material of the flexible silica gel seat 70 can be in the range of Shore A type 20A to 40A; so that when the negative pressure in the reservoir chamber 12 is gradually increased, the pressure at the upper end of the first shielding portion 73 is reduced by the fluid transmission, so that it can form the upward-tilted deformation shown in fig. 9, and a gap with the exposed portion at the upper end of the through hole 63, thereby allowing the external air to enter the reservoir chamber 12 along the arrow R3 shown in fig. 9 to eliminate the negative pressure.

As can be seen from fig. 4, 8 and 9, the first shielding portion 73 of the flexible silicone seat 70 is disposed close to the first liquid guiding channel 71, so that the first shielding portion 73 is more easily deformed by opening the first liquid guiding channel 71 to reduce the bending strength of the first shielding portion 73. Alternatively, a plurality of through holes, grooves, notches, recesses, and the like surrounding the first shielding portion 73 may be additionally formed to have a reinforcing structure 74b/741b for reducing the bending strength of the first shielding portion 73 and making it easier to tilt or deform, as shown in fig. 14.

In a manner different from the manner in which the first shielding portion 73 shields against the surface of the port of the through-hole 63; as further shown in fig. 7 to 9, the rigid supporting frame 60 is provided with a first concave structure 65, and the first concave structure 65 is further provided therein with a through hole 651 opposite to the second insertion hole 62, the through hole 651 is in airflow communication with the second insertion hole 62 and further in airflow communication with the air intake hole 24 and even the outside air; therefore, air can be subsequently fed into the liquid storage cavity 12 through the through hole 651 to eliminate the negative pressure of the liquid storage cavity 12; in order to assist the through hole 651 to communicate with the air flow of the liquid storage chamber 12, the supporting frame 60 is provided with a vent groove 66, which extends from the first concave structure 65 to the second liquid guide channel 62 and is an air channel for allowing the air in the flue gas delivery pipe 11 to enter the liquid storage chamber 12.

The upper end of the flexible silicone sleeve 50 is correspondingly provided with a second shielding part 52 which can extend into the first concave structure 65, and after installation, the second shielding part 52 of the flexible silicone sleeve 50 extends upwards into the first concave structure 65 and shields the through hole 651, and of course, also shields the port of the vent groove 66, as shown in fig. 8. Further, when the interior of the reservoir chamber 12 becomes a negative pressure, the second shielding portion 52 is deformed by the pressure transmission of the fluid and is contracted downward to the state shown in fig. 9, so that a part of the port of the vent groove 66 and the shielded through hole 651 is exposed, and the through hole 651 is communicated with the reservoir chamber 12 through the vent groove 66, so that the outside air enters the reservoir chamber 12 as shown by an arrow R4 in fig. 9 to reduce the negative pressure to some extent.

In design, referring to fig. 10, the second shielding portion 52 of the flexible silicone sleeve 50 is located between the two third fluid conducting channels 51, and is beneficial to deformation by reducing the bending strength. The thickness is reduced to about 0.2-0.5 mm, and the Shore A hardness is in the range of 20A-40A. In order to improve the tendency of greater deformation under lower pressure, the second shielding part 52 itself is not in a planar shape, but in a concave-convex wavy shape, and a second concave structure 521 opposite to the convex direction is arranged in the center of the second shielding part 52, and the second concave structure 521 is used for reducing the thickness of the second shielding part 52 on one hand, and further reducing the bending strength on the other hand, so that the deformation is more easily generated.
