DETAILED DESCRIPTION
[0049] Specific embodiments of the present disclosure will be
described in detail below with reference to the drawings. It should
be understood that the specific embodiments described herein are
for the purpose of illustration and explanation of the present
disclosure, and are not intended to limit the disclosure.
[0050] As shown in FIGS. 1-4, a cigarette mouthpiece for an
electronic cigarette is provided in the present disclosure. The
cigarette mouthpiece comprises a hard substrate 10. A soft
substrate 20 is mounted on the outside of the hard substrate 10. In
one embodiment, the hard substrate 10 is made of one of a group of
hard plastic, stainless steel and glass. It can be appreciated that
the hard substrate 10 can be made of other hard materials to
support the soft substrate 20. A through hole (not shown) is
defined inside the hard substrate 10 and extends through two
opposite ends of the hard substrate 10. The through hole is mainly
configured as a smoke passage when the user inhales. It can be
appreciated that the electronic cigarette is an automatic
electronic cigarette and an independent inductive passage can be
defined inside the through hole.
[0051] In one embodiment, the hard substrate 10 having an
approximately flat shape comprises a top end 11 and a bottom end 12
opposite to the top end 11. The bottom end 12 is relatively wider
than the top end 11 and is configured to connect to a main body 31
of a cartomizer. The bottom end 12 can have any shape, such as a
rectangular parallelepiped shape or a cylindrical shape. In one
embodiment, the bottom end 12 is detachably connected to the main
body 31 by clamping or screwing. It can be appreciated that the
fixed connection, such as snap fit connection, is also applicable.
In this embodiment, the cigarette mouthpiece and the main body 31
are fixed together via a latching structure 19. In this embodiment,
the top end 11 has a rectangular parallelepiped shape. It can be
appreciated that, the top end 11 can have any shape, such as a
cylindrical shape or an ellipse cylinder shape.
[0052] A concave portion 18 is defined on the hard substrate 10 and
located between the top end 11 and the bottom end 12. In one
embodiment, there are two concave portions 18. The two concave
portions 18 are located on the front side and the rear side of the
hard substrate 18, respectively. In one embodiment, each concave
portion 18 defines a groove 14. When the soft substrate 20 is
mounted in the groove 14, the outer surface of the entire concave
portion 18 becomes a smooth curved surface accordingly.
[0053] A through hole is defined inside the hard substrate 10 and
extends through the top end 11 and the bottom end 12. Smoke outlet
17 is the opening of the through hole located at the top end
11.
[0054] When the user inhales, the smoke can be sucked off from the
smoke outlet 17. The lips of the user contact with the soft
substrate 20, and the user can obtain comfortable tactility.
[0055] The soft substrate 20 can be made of elastic materials. The
appropriate elastic material can be selected from one of a group of
silicone resin, latex, thermoplastic elastomer (TPE),
ethylene-vinyl acetate copolymer (EVA) and soft silicone rubber. It
can be appreciated that other soft and environmentally friendly
materials are also applicable.
[0056] Both of the opposite sides of the hard substrate 10 define a
groove 14, and the two soft substrates 20 are mounted in the
corresponding grooves 14 respectively.
[0057] In one embodiment, the soft substrate 20 is a sheet.
Specifically, soft substrate 20 has a shape selected from one of a
group of circular, square and ellipse. Furthermore, the two ends of
the soft substrate 20 are relatively thinner than the middle
portion of the soft substrate 20. The shape of the groove 14 is
configured to fit such soft substrate 20.
[0058] In one embodiment, the soft substrate 20 is melted at a high
temperature and then adhered to the groove 14.
[0059] As shown in FIG. 5 and FIG. 6, in one embodiment, the soft
substrate 20 is disposed around the hard substrate 10. That is, the
soft substrate 20 has a sleeve shape and is sleeved on the outside
of the hard substrate 10. In one embodiment, a retaining protrusion
13 is defined on the concave portion 18, and a retaining hole 21
corresponding to the retaining protrusion 13 is defined on the soft
substrate 20. The retaining protrusion 13 inserts into the
retaining hole 21 to prevent the soft substrate 20 from
slipping.
[0060] It can be appreciated that two retaining protrusions 13
configured to retain the soft substrate 20 can be defined on the
outside of the hard substrate 10 along the circumferential
direction of the hard substrate 10. One retaining protrusion 13 is
adjacent to the top end 11, and the other retaining protrusion 13
is adjacent to the bottom end 12. The soft substrate 20 is located
between the two retaining protrusions 13.
[0061] As shown in FIGS. 7-9, in another embodiment, the hard
substrate 10 has an approximately cylindrical shape and comprises
an upper section 15 and a lower section 16. The diameter of the
lower section 16 is larger than that of the upper section 15. A
through hole is defined inside the hard substrate 10 and extends
through the upper section 15 and the lower section 16. The top end
of the through hole is the smoke outlet 17. A groove 14 is defined
on the outside of the upper section 15 along the circumferential
direction of the upper section 15. The soft substrate 20 is mounted
on the outside of the upper section 15 along the circumferential
direction of the upper section 15. Specifically, the soft substrate
20 has a sleeve shape and located in the groove 14. When the soft
substrate 20 is mounted in the groove 14, the outer surface of the
entire upper section 15 becomes a smooth curved surface.
[0062] In one embodiment, there is no concave portion 18 defined on
the hard substrate 10. That is, between the top end 11 and the
bottom end 12, there is no curved surface or planar surface defined
inclining to the central axis of the cigarette mouthpiece.
Furthermore, the shape of the hard substrate 10 is selected from
one of a group of cylinder, frustum of a prism and frustum of a
cone. Furthermore, a groove 14 is defined on the hard substrate 10,
and the soft substrate 20 is mounted in the groove 14.
Alternatively, there is no groove 14 defined on the hard substrate
10, and the soft substrate 20 is directly mounted on the hard
substrate 10.
[0063] In one embodiment, the connection method between the soft
substrate 20 and the hard substrate 10 includes, but is not limited
to, adhesion and sleeving.
[0064] In one embodiment, a cartomizer is provided. The cartomizer
comprises a main body 31 and a cigarette mouthpiece mounted on the
top end of the main body 31. A liquid storage chamber is defined in
the main body 31. The cigarette mouthpiece is any one of the
cigarette mouthpieces described in the previous embodiments.
[0065] In one embodiment, an electronic cigarette is provided which
comprises a cartomizer described in the previous embodiment.
[0066] In one embodiment, an electronic cigarette is provided which
comprises a cigarette mouthpiece described in any one of the
previous embodiments.
[0067] The cigarette mouthpiece provided in the present disclosure
comprises a hard substrate 10 and a soft substrate 20 mounted on
the hard substrate 10. Accordingly, the user's lips can obtain soft
and comfortable tactility when in contact with the cigarette
mouthpiece. At the same time, the use of the hard substrate 10 in
cooperation with the soft substrate 20 ensures the reliability of
the cigarette mouthpiece, reduces the risk of contamination and
prolongs the service life.
[0068] Any combination made to various embodiments of the present
disclosure without departing from the spirit of the disclosure
should be regarded as the disclosure of the present disclosure;
various simple modifications made to the technical solution or any
combination made to the various embodiments without violating the
technical spirit of the disclosure is intended to be within the
scope of the present disclosure.
