Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an air pot, and particularly to a shoulder cover thereof.

[Conventional technology]

The front part of the air pot has a mounting part for the outlet,
Since the strainer and the like connected to the discharge port are exposed, in conventional air pots, a shoulder cover is attached to cover these parts.

[Problem that the invention attempts to solve]

In order to reduce the height of the air pot as much as possible, when attaching an air pump that is conventionally built into the lid to the front of the shoulder body, it is not economical to provide a separate compartment for the pump and the structure is complicated. Therefore, there is an undesirable problem in terms of design.

Therefore, the object of this invention is to solve the above-mentioned problems by adding a twist to the conventional shoulder cover and integrating the pump accommodating portion with the shoulder cover.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention provides a recess in the shoulder body with an open area extending from the front surface to the upper surface, and the pump is mounted while being partially inserted into the front part of the recess. A liquid discharge port is arranged directly below or near the pump, and the pump
A shoulder cover is attached to the shoulder body to integrally cover the discharge port and the opening of the recess.

〔Example〕

As shown in FIGS. 1 and 2, the air pot of the embodiment shown in the attached drawings has a bellows type air pump 1 mounted on the upper front surface of the pot, and a discharge port 2 provided directly below it. By pushing down a push button 3 placed on the air pump 1, the inside of the container 4 is pressurized and hot water is discharged from the discharge port 2.

The container 4 consists of a vacuum double bottle, and the tip 5 on the bottom is of the so-called sandwich type, and consideration is given to reducing the height of the pot in this aspect as well.

The shoulder body 7, which is placed on the opening 15 of the container 4 via the packing 6, engages the upper edge of the body 8 at its lower end, and is fastened to the center part of the bottom body 9, which is screwed to the lower edge of the body 8. The raising body 10 is screwed together, the bottom surface of the container 4 is tightened by the tightening body 10, and the container 4, shoulder body 7, body 8, and bottom body 9 are integrated. Shoulder body 7 is body 8
The outer peripheral wall 11 and the lid body 12 are formed to have approximately the same diameter.
The upper surface portion 13 and the lid body 12 are formed on substantially the same plane as the
It consists of an inner circumferential wall 14 into which the container 4 is fitted, and a small-diameter cylindrical portion 16 that rests on the mouth 15 of the container 4.

As shown in FIG. 3, the shoulder body 7 has a recess 17 formed in its front surface with an open outer circumferential wall 11 and an open upper surface 13. This recess 17
are both side walls 18, inner wall 19, top wall 20 and bottom wall 2.
1, and the inner wall 19 is formed by the inner peripheral wall 1 of the shoulder body 7.
4 (see Fig. 2). Therefore, a portion of the lid body 12 is also recessed in accordance with the recessed shape of the inner wall 19. Furthermore, an air hole 23, a discharge hole 24, and an air vent hole 25 are formed in the inner wall 19. A pumping pipe 26 is connected to the inner end of the discharge hole 24 .

A circumferential wall 27 is formed at the outer circumferential edge of the upper wall 20 in an arc shape, which is continuous with the arc of the open end of the inner circumferential wall 14 of the shoulder body 7, and is adapted to receive the outer circumference of the upper end of the lid body 12.

The bottom wall 21 has insertion holes 29', 3 into which the three claw plates 29, 30, 31 of the bellows lower plate 28 are inserted.
0', 31' are formed, one of which has a fixed part 3.
6 is provided, and the bellows lower plate 28 is fixed to its fixing part 36.
and fix it with screws 37 (see Figure 2). Support ribs 32, 33, 34 of the safety valve device 38 are formed on each of the insertion holes 29', 30', 31'. Further, a pair of opposing receiving claws 39 are formed at the front end of the bottom wall 21 and project forward from the body 8 to receive the bellows lower plate 28. A shoulder cover bottom plate 4 is provided on the bottom surface of the bellows lower plate 28.
4 is attached with screws 51 (see FIG. 2). A discharge port 2 is provided in the bottom plate 44.

A safety valve device 38 is installed inside the recess 17 described above. The safety valve device 38 prevents hot water from being discharged when the pot topples, and also prevents children from inhaling hot water by directly putting their mouths on the discharge port 2.

The safety valve device 38 is connected to the air hole 23, the discharge hole 24, and the air vent hole 25 of the shoulder body 7, and is further connected to the bellows lower plate 28 by the air tube 40.
is connected to the air hole 41 of the
2 is connected to the outlet 2 of the bottom plate 44.

Bellows lower plate 28, bottom plate 44 and safety valve device 3
8 are assembled as described above, a shoulder cover 43 is attached to their front surfaces to cover the recess 17 of the shoulder body 7.

As shown in FIG. 3, the shoulder cover 43 is surrounded by an arcuate side 45 along the aforementioned peripheral wall 27 and a curved side 46 along both side walls 18, and covers the upper surface of the shoulder body 7 as a whole. It has a curved cover surface 47 that covers a range from 13 to along the outer peripheral wall 11, and a cylindrical guide tube 48 that projects forward is formed on the curved cover surface 47. Guide tube 48
A guide rib 50 is provided on the inner circumferential surface of.

The shoulder cover 43 is engaged with the peripheral wall 27 at its arcuate side 45, and is engaged with the bottom plate 44 at the lower end of the guide tube 48.

The bellows air pump 1 is inserted into the guide tube 48 described above. The lower end of the air pump 1 is welded and fixed on the bellows lower plate 28, and the air pump 1
The push button 3 is in sliding contact with the guide rib 50.

The air pot of the embodiment has the above configuration, and as can be clearly seen in FIG. 2, the center line l of the air pump 1 is located somewhat forward of the body 8, and the amount of forward protrusion of the air pump 1 is as follows. When a downward pressing force is applied on this center line, the pot is set within a range where the pot does not fall over due to the center of gravity being shifted to one side. That is, the air pump 1 is not mounted so that its entirety protrudes forward from the body 8, but is partially inserted into the front part of the recess 17 provided in the shoulder body 7, and the amount of protrusion is reduced by that amount. is decreasing. In addition, in order to increase safety, the bottom body 9 may be provided with supporting legs 51 that protrude forward.

The discharge port 2 does not necessarily need to be located on the above-mentioned centerline 1, but is disposed near the centerline 1 in the front of the body 8, that is, directly below the air pump 1.

Now, when the push button 3 of the air pump 1 is pressed down, pressurized air is sent in the order of the air pump 1 → air tube 40 → safety valve device 38 → air hole 23 → container 4, pressurizing the inside of the container 4 (see Fig. 4). (see route a). Further, when the internal pressure of the container 4 increases, the hot water in the container 4 flows from the pumping pipe 26 → the discharge hole 24 → the safety valve device 38 → the discharge tube 42 →
The liquid is discharged in the order of discharge port 2 (see path b in FIG. 4).

Note that the airtightness test at the factory before shipping is performed by sucking internal air from the discharge port 2 with the air vent hole 25 closed.

[Effect of idea]

As described above, this invention uses an integrated shoulder cover to cover the pump, discharge port, other parts, and the open part of the shoulder body recess, thereby eliminating the need for a separate storage area for the pump, and by using an integrated shoulder cover. Since the shoulder cover covers all of these parts, it has a good appearance in terms of design.
