Abstract
A tobacco filling device includes a base with an outlet defined in a first end thereof and a cover is pivotally connected to a second end of the base. A pushing member is movably engaged with a slot defined in a top surface of the base. A plurality of pawls are connected to a top surface of the pushing member and each pawls has an end extending upward and away from the outlet. A knob is connected to the pushing member.
Description
FIELD OF THE INVENTION
The present invention relates to a tobacco filling device which has a pushing member with a plurality of pawls extending from a top surface thereof and each pawls extending upward so as to fit the tobacco in the cigarette.
BACKGROUND OF THE INVENTION
A conventional tobacco filling device for filling tobacco into a cigarette is shown in FIG.
4
and includes a base
1
with a pushing member
12
movably received therein, an outlet
11
defined in an end of the base
1
, a cover
13
movably connected to the other end of the base
1
. The cover
13
has a pressing member
15
for pressing the tobacco in the pushing member
12
to be a desired shape and a fixing member
14
which is used to fix the cigarette at the outlet
11
. The user has to hold the base
1
by one hand and push the cover
13
toward the outlet
11
with the other hand. After the tobacco in the pushing member
12
is sent in the cigarette, the cover
13
is moved backward. However, some of the tobacco will be brought out from the cigarette when moving the pushing member
12
backward.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a tobacco filling device which comprises a base having an outlet defined in a first end thereof and a positioning tube is connected to a top surface of the first end of the base. A cover has a first end thereof pivotally connected to a second end of the base and a pressing member is connected to an underside of the cover. A fixing member is retractably connected the underside of a second end of the cover and located in alignment with the positioning tube. A pushing member is movably engaged with a slot in the base and a plurality of pawls are connected to a top surface of the pushing member. Each pawls has a first end fixed on the pushing member and a second end of each pawls extends upward and away from the positioning tube.
The primary object of the present invention is to provide a tobacco filling device wherein the tobacco is not brought from the cigarette when moving backward the pushing member.
Another object of the present invention is to provide a tobacco filling device that is easily to fill the cigarette by one hand.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1
is a perspective view to show the tobacco filling device of the present invention;
FIG. 2
is a cross sectional view to show the tobacco filling device of the present invention;
FIG. 3
is a perspective view to show the pushing member of the tobacco filling device of the present invention, and
FIG. 4
is a top view to show a conventional tobacco filling device.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to
FIGS. 1
to
3
, the tobacco filling device of the present invention comprises a base
2
which has an outlet
24
defined in a first end thereof and a positioning tube
240
is connected to a top surface of the first end of the base
2
. A slot
23
is defined in the top surface of the base
2
and two pushing, plates
21
are located at two sides of the positioning tube
240
and biased by two respective spring
22
.
A pushing member
4
has an extension portion
42
which slidably extends through the slot
23
and is able to move along the slot
23
. A plurality of pawls
41
are connected to a top surface of the pushing member
4
. Each pawls
41
has a first end fixed on the pushing member
4
and a second end of each pawls
41
extends upward and away from the positioning tube
240
so as to form an inclined surface
411
on each pawl
41
. A knob
5
having a threaded hole
51
defined therein is connected to the pushing member
4
by a bolt
52
extending through a top hole
43
in the extension portion
42
and threadedly engaged with the threaded hole
51
in the knob
5
. The knob
5
is located at an underside of the base
2
so that the user can conveniently hold the knob
5
to slide the pushing member
4
.
A cover
3
has a first end thereof pivotally connected to a second end of the base
2
and a pressing, member
34
is connected to an underside of the cover
3
. A fixing member
32
is retractably connected the underside of a second end of the cover
3
and located in alignment with the positioning tube
240
. Two engaging plates
31
extend from two sides of the second end of the cover
3
. A torsion spring
35
has a first end mounted to a shaft extending through the first end of the cover
3
and the second end of the base
2
, a second end of the torsion spring
35
being biased at the underside of the cover
3
.
When in use, tobacco is put on the pushing member
4
and the cover
3
is mounted on the base
2
by engaging the two engaging plates
31
with the two pushing plates
21
. Therefore, the user needs not to hold the cover
3
. The tobacco on the pushing member
4
is pressed by the pressing member
34
and the user then slides the knob
5
to push the tobacco into the cigarette
6
which is inserted in the outlet
24
and clamped by the engagement of the fixing member
32
and the positioning tube
240
.
The shape of the pawls
41
effectively push the tobacco into the cigarette
6
and when the pushing member
4
is moved backward, no tobacco is brought from the cigarette
6
.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
