Description

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

Generally, as is well known, in a conventional air pot, a lid housing a built-in 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 inlet for injecting liquid into the container is formed in the inner lid, and the water inlet is connected to the inner lid. The stopper is removably fitted.

Further, a bellows constituting an air pump is housed within the lid body.

The bellows is compressed by a pushing body provided in a mounting recess formed in the outer lid so as to be movable up and down.

That is, this pushing body is provided with a shaft whose lower end protrudes into the lid body from the bottom plate of the mounting recess, and a contact member is provided at the lower end of this shaft so as to be located on the lower surface side of the bottom plate of the mounting recess. ing.

When the pushing body is pressed down and the bellows is compressed by the abutting body, the liquid inside the housing is pressurized and ejected by the pressurized air jetted from the bellows into the housing.

By the way, according to the air pot having such a configuration, the height of the lid body is equal to the height of the bellows and the depth of the mounting recess, that is, the height of the bellows required to compress the bellows to discharge liquid from the container. It is determined by the stroke dimension of the pushing body and the thickness dimension of the abutting body provided integrally with the pushing body located between the lower surface of the mounting recess and the upper end surface of the bellows.

On the other hand, in an air pot, it is desirable to be able to discharge as much liquid as possible with one pressing and lowering operation of the pusher.

To do this, the mounting recess is deepened, the stroke of the pushing body provided in the mounting recess is increased, and this step I~
The height of the bellows must be increased depending on the rotation.

However, if the mounting recess is deepened or the height of the bellows is increased, the height of the lid must be increased accordingly, resulting in the inconvenience of an increase in the size of the lid.

The present invention was developed based on the above circumstances, and its purpose is to increase the amount of liquid discharged by one pressing and lowering operation of the pusher without increasing the height of the lid. The purpose of the present invention is to provide an air pot that can be used for various purposes.

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 frame 4. .

Therefore, when the bellows 29 is compressed as described above, the air inside the bellows 29 is pressurized and the second and third passages (
Since the liquid is ejected into the container 8 through the L 43 and 44 and pressurizes the liquid level of the liquid contained in the container 8, the liquid flows out from the outlet path 24 through 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 14, for example, the temperature that is just right for brewing coffee or tea, etc. The heating coil 13 of the heater 12 is energized by the signal from the temperature controller 14a to heat the liquid tank.

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.

By the way, in the present invention, the bellows 29 is located between the lower surface side of the bottom plate 33 of the mounting recess 32 formed in the tab cover 19 and the upper plate 31 attached to the upper end of the bellows 29.
By forming the bottom plate 33 of the mounting recess 32 to bulge into the recess 32, a contact body 39 for compressing the mounting recess 32 is formed.
It was housed in a housing recess 34 formed on the lower surface side of the bottom plate 33.

Therefore, since the thickness of this abutment body 39 has no effect on the height of the lid formed by the inner lid 2 and the outer lid 19, the thickness of the abutment body 39 is equal to the height of the lid. The height dimension of can be reduced.

In other words, the height of the contact body 39 can be increased without increasing the height of the lid.
By increasing the stroke of the pushing body 35 or the height of the bellows 29 by the height dimension, it is possible to increase the amount of liquid discharged by one pressing downward operation of the pushing body 35.

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.

As described above, in the present invention, the bottom plate of the mounting recess formed in the outer lid constituting the lid body is bulged into the recess to form an accommodation recess on the lower surface side of the bottom plate, and in this accommodation recess, Since the abutting body is provided integrally with the pushing body housed in the mounting recess so as to be movable up and down, and compresses the bellows installed inside the lid by pressing and lowering the pushing body, the abutting body 'The height of the lid does not increase due to the thickness.

In other words, without increasing the height of the lid, the height of the loaf or bellows of the pusher can be increased to increase the amount of liquid discharged by one pressing and lowering operation of the pusher. This has a great practical effect.
