Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air pot that pressurizes and discharges liquid within a container using a pump mechanism.

Generally, as is well known, in a conventional air pot, a lid having a built-in pump mechanism such as an air pump is provided on the open upper surface of a container made of a double glass bottle so as to close the opening.

This lid body consists of an inner lid and an outer lid rotatably connected to the inner lid, and a water supply port for injecting liquid into the container is formed in the inner lid.

A plug is removably fitted into this water supply port.

This stopper is provided with a through hole that communicates the pump mechanism with the housing.

The stopper also holds a lower conduit whose lower end faces the bottom of the housing body, and an upper conduit whose one end is connected to the upper end of the lower conduit via a check valve mechanism.

By operating the pump mechanism to pressurize the liquid level within the container, the liquid is discharged from the other end of the upper conduit via the lower conduit and the check valve mechanism.

By the way, in an air pot with such a configuration,
The stopper must be removed from the water supply port each time liquid is injected into the container, but when the stopper is attached or removed, the upper and lower conduits held by the stopper may hit the inner surface of the container or other parts. There is.

If this happens, the parts held by the plugs of the upper and lower conduits may become loose and loose, or the connection between the upper and lower conduits via the check valve may deteriorate, causing liquid to leak from the connection. There is.

Further, if the container is a glass bottle and the conduit is made of metal, the container may be damaged when the conduit hits the container.

The present invention was developed based on the above-mentioned circumstances, and its purpose is to provide a conduit that is held in the lid, so that when liquid is injected into the container, the conduit collides with the container. An object of the present invention is to provide an air pot that does not cause damage to a container or a conduit.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In the figure, 1 is a bottomed cylindrical case with an open top.

An inner lid 2 is provided on the upper surface of the case 1 so as to close the upper surface opening.

The heater 12 is electrically connected to a magnetic I-type plug receiver 15 provided on the lower circumferential surface of the case 1 via the temperature controller 14a.

A plug 16 is connected to the magnetic plug receiver 15 by magnetic force.

This plug 16 is connected to a power source (not shown) via a cord 17.

Therefore, if your foot accidentally gets caught on this cord 17, the plug 16 will be removed from the magnetic plug receiver 15.
Since it can be easily removed from the case, the case 1 will not fall over.

Furthermore, a heat insulating material 18 is filled between the inner circumferential surface of the case 1 and the outer circumferential surface of the container 8.

On the other hand, an outer cover 19 is rotatably connected to the inner cover 2 by a shaft 20.

This outer lid 19 and the inner lid 2 each have a protruding portion 19a.
, 2a are formed.

A hook 20 that engages with a locking part (not shown) protruding from the protrusion 2a of the inner cover 2 is pivotally supported on the protrusion 19a of the outer cover 19 and is biased by a spring 21. The outer lid 19 can be opened by pressing and rotating the hook 20 in the direction of the arrow to disengage it from the locking portion.

Further, as shown in FIG. 2, the inner lid 2 is formed with a connection port 22 consisting of a large diameter portion 22a and a narrow diameter portion 22b. A conduit 23 facing the inner bottom of the container 8 is connected thereto.

This conduit 23 communicates with an outlet path 24 formed on the upper surface of the inner lid 2 via the connection port 22 .

The tip of this lead-out path 24 is open downward from the protrusion 2a of the inner lid 2.

Further, a plurality of blades 22C... are provided on the inner circumferential surface of the large diameter portion 22a of the connection port 22, and these blades 22C...
A cylindrical closure 25 is provided so as to be movable up and down with its lower end in contact with C..., forming a check valve mechanism. It moves to the position shown by and closes the opening JL2a formed in the inner lid 2 that communicates the outlet path 24 and the conduit 23, thereby preventing liquid such as hot water stored in the container 8 from flowing out. It is supposed to be done.

Further, a mounting plate 28 is provided in the outer lid 19, the lower surface of which is hermetically joined to a wall portion 26 which projects annularly from the upper surface of the frame 4 via a backing 27.

A bellows 29 constituting a pump mechanism is provided on the upper surface of this mounting plate 28 with its lower end connected.

A first spring 30 is housed inside the bellows 29, and an upper plate 31 is attached to the upper end.

Furthermore, the outer lid 19 is formed with four mounting parts 32 whose upper surfaces are open.

The bottom plate 33 of the mounting recess 32 has a central portion bulged upward, and a four-accommodating portion 34 is formed on the lower surface thereof.

Further, in the mounting recess 32, a push body 35 formed in a hat shape is provided.

Further, a first through hole 42 to which an annular backing 41 is attached is formed in a portion of the upper plate 31 facing the abutting body 39 .

Therefore, the first through hole 42 is normally open, but when the pushing body 35 is pressed down, the first through hole 42 is closed by the contact body 39, and in this state, the bellows 29 is compressed. be done.

On the other hand, a plurality of second through holes 43 are formed in the mounting plate 28, and a third through hole 44 is formed in a portion surrounded by the wall 26 of the plug 4. .

Therefore, when the bellows 29 is compressed as described above, the air inside the bellows 29 is pressurized and ejected into the container 8 through the second and third through holes 43,44,
Since the liquid level of the liquid tank contained in the tank is pressurized, the liquid tank flows out from the outlet passage 24 via the conduit 23.

Note that 45 in the figure is a handle whose both ends are rotatably connected to the case 1.

According to the above configuration, when the temperature of the liquid such as water stored in the container 8 is lower than the set temperature of the temperature controller 14a, for example, the temperature that is just right for brewing coffee, tea, etc. The heating coil 13 of the heater 12 is energized by the signal from the temperature controller 14a,
Heat the above liquid.

When the liquid temperature rises to the set temperature, the heating coil 13 is activated by a signal from the temperature controller 14a.
When the current is turned off, the heat-retaining coil 14 is energized, and the heat-retaining coil 14 keeps the liquid warm.

Therefore, the liquid contained in the container 8 is always maintained at a predetermined temperature and never cools down, so that hot water at a high temperature can be used at any time, which is convenient.

When the liquid in the container 8 runs out and you want to replenish the liquid, open the outer cover 19 while pressing the hook 20, and then remove the stopper 4 fitted into the water supply port 3 of the inner cover 2. ,
It is sufficient to inject liquid into the container 8 through the water supply port 3, but at this time, the stopper 4 does not hold a conduit as in the conventional air pot.

Therefore, when replenishing the liquid, there is no risk of the conduit 23 hitting the inner surface of the container 8.
or damage the conduit 23.

In the above embodiment, the container is made of metal and the pot is heated and kept warm by a heater.
There is no problem even if it is made of heavy glass bottles.

Further, the pump mechanism may be an electric pump instead of the bellows.

Furthermore, in the above embodiment, a conduit was connected to the connection port formed in the inner lid, and the liquid discharged from the conduit was led out from the lid through the outlet path formed on the upper surface of the inner lid.
The above-mentioned lead-out path may be constructed of a pipe-like member in the same way as the conduit.

As described above, the present invention has a structure in which a
A lid body consisting of an inner lid that closes this opening and an outer lid rotatably connected to the inner lid is provided, and the upper end of the conduit is connected to the inner lid of the lid body via a check valve mechanism. Therefore, there is no need to hold a conduit in the stopper that is fitted into the water supply port formed in the inner lid.

Therefore, when replenishing the container with liquid, by attaching and removing the stopper as in the past, the conduit held by the stopper may hit the inner surface of the container, damaging the container or damaging the holding state of the conduit. This has a great practical effect in that there is no such problem.
