Insulated bucket with air pump

The present invention relates to an air compressed thermal bucket and, more particularly, to an air compressed thermal bucket, in which the drain pipe may be laid on the bucket body at users' will and the outlet may be automatically locked by way of a locked mechanism to prevent boiling water within the bucket from spilling over and to prevent loss of heat.

BACKGROUND OF THE INVENTION 
The present invention relates to an air compressed thermal bucket and 
particularly to an air compressed thermal bucket with novel and simple 
construction which is convenient to users in usage. 
Heretofore, the general buckets for containing boiling water include the 
oldest type tea bucket made in metal and the most currently prevailing 
thermal tea bucket. Those mentioned tea buckets usually operate by means 
of a faucet mounted on lateral side of bucket body for draining off and 
locking tea water within the bucket. In order to have water stored within 
the bucket drained off as clearly as possible, the faucet is always to be 
fixed near the bottom. However, this installation makes users getting more 
inconvenient by virtue of the height of the faucet lower than a cup. 
The object of the present invention is an improvement over the mentioned 
tea buckets in the respect of usage and to disclose an air compressed 
thermos bucket with novel and simple construction which has some effective 
achievements. 
SUMMARY OF THE INVENTION 
In accordance with the present invention, the air compressed bucket is 
comprised of: 
a centally spaced bucket body which is made from heatkeeping material and 
provided at central position of its upper part with an opening having 
screw threads on inner wall, and a stop annular mouth is formed at the 
bottom side of said opening so as to allow to be engaged with a cork 
member; 
a cork member, at the mid position of which is provided with an air hole 
communicable with inside of the bucket body; 
an air compressed mechanism having an elastic pouch, which is fastenedly 
screwed on the cork member's top of the said opening of the bucket and is 
provided with an exhaust exit at bottom communicating with said air hole 
of the cork member; 
a L-shaped delivery tube planted on the top of the bucket body, in which 
one end of the L-shaped delvery tube deepens into inside of the bucket 
body directly to the bottom and the other end able to be turned 
arbitrarily extends out of the bucket body; 
a cap body provided in the inside of upper part of the bucket body and able 
to shift up and down, the cap head's end of which comes slightly cut of 
the top of the bucket body. 
The other object of the present invention is to provide an air compressed 
thermal bucket, in which the L-shaped delivery tube comprises the lower 
part called the suction pipe depending down into the inside of the bucket 
body and the upper part called the drain pipe extending out of the top of 
the bucket body. The advantage of this invention is that the drain pipe 
can be turned in clockwise or counter-clockwise direction in users' will 
so as to be laid on the top of the bucket body while not being used, and 
the outlet at the front end of the drain pipe may engage with the cap 
head's end of the cap body to block the outlet, preventing boiling water 
within the bucket from spilling over to scald human body or preventing 
heat from loss to lose efficacy of heat-keeping.

DETAILED DESCRIPTION 
Referring the drawings attached herewith, the air compressed thermos bucket 
of the present invention comprises a bucket body 10 having spaced double 
walls 12, 14 between which is filled with heat-keeping material 62 such as 
poly-nylon. At the central position of the upper part of the bucket body 
10, there is an opening 18 with screw threads 16, and a stop annular mouth 
or ledge 20 is formed at the bottom side of said opening 18 so that a 
stopper disc cork member 22 may properly stuff into or seated on the stop 
annular mouth or ledge 20. And, a projected portion 26 with air hole 24 is 
projected upward from the mid position of the cork member 22. In addition 
to above construction, an air compressed mechanism 30 having an elastic 
pouch 28 is fastenedly screwed on the cork member's 22 top of the opening 
18 of the bucket body 22. 
The air compressed mechanism 30 as shown in FIG. 3 is comprised of a 
cylindrical case 34, with circular hole 32a at top end and screw threads 
32 at lower side for screwing engagement with screw threads 16 provided at 
the opening of the bucket body 10, an elastic pouch 28, a pressed member 
36 used for pressing said elastic pouch 28, and a bottom base 40 fixed at 
the bottom of the elastic pouch 28. At center of said bottom base 40, a 
round jut 44 having exhaust exit 42 is provided, in which the round jut 44 
is made from soft reisn or rubber so the exhaust exit 42 may communicate 
with above mentioned air hole 24 of the cork member 22 and keep air from 
leaking out. 
A L-shaped delivery tube 48 able to turned in users' will is planted on the 
top 46 of bucket body 10 near the air compressed mechanism 30, in which 
the delivery tube 48 is pivoted on the top 46 of the bucket body 10 by 
means of two fixed rings 50, comprising the lower part called the suction 
pipe 48 deepening into inside of the bucket body 10 and the upper part 
called the drain pipe 48b extending out of the bucket body 10. In figures, 
the indicated member 52 means the lever member 52 covering over the drain 
pipe 48b, which may be turned following the drain pipe 48b turning. When 
it is desirous to drain water off, the drain pipe 48b accompanying with 
the lever member 52 can be turned to the position shown in FIG. 2 and then 
the user may press the pressed member 36 to depress the elastic pouch 28 
in shrinkage to compress air within the elastic pouch 28 into the bucket 
body 10 through the exhaust exit 42 and the air hole 24, so the air will 
add pressure on the level of boiling water within the bucket body 10 to 
have boiling water drained off from the outlet 54 through the suction 48a 
and the drain pipe 48b. However, when the thermal bucket of the invention 
is not being used, the drain pipe 48b and the lever member 52 may be 
turned to lay on the top 46 of the bucket body 10, and carefully to have 
the outlet 54 engaged with the cap head's 56a end of the cap body 56 to 
block the outlet 54, preventing boiling water within the bucket from 
spilling over to scald human body or keeping heat from loss to lose 
efficacy of heat-keeping. 
Now specifically referring FIG. 4, the above mentioned cap body 56 is 
planted in the sloted hole 58 of the upper part of the bucket body 10, 
comprising a cap head 56, which comes slightly out of the top 46 of the 
bucket body 10, and an axle bar 56b. The axle bar or stem 56b is provided 
with a compressed spring 64 for urging the cap head 56a to automatically 
shift up and down that will be to the advantage of the outlet 54 cross 
over the cap head 56a and will fortify the function of blocking outlet 54. 
In FIG. 1, the section, a certain area of the top 46 of the bucket body 
10, where the delivery tube 48 and the cap body 56 are planted on is 
schemed in forming to be a concave through 60 in slight triangular shape 
so that the drain pipe 48b will be defined between two specified 
positions, A and B shown in FIG. 1, for its anchorage and turning.
