Leak-proof valve device for pump type thermos

1 is a sectional view showing main parts of an electric pot according to an embodiment of the present invention.

2 is an enlarged exploded view of the leakage preventing valve unit part in the electric pot.

The present invention relates to a leak-proof valve device in a pump-type thermos called so-called electric pot or air pot. In order to prevent the liquid from leaking out when the thermos is inverted, various types of thermos (not pump type) are known, but it is known by the inner tube and the outer tube (middle illness). In the pump-type thermos communicating the inside and outside of the body, the effective structure for closing the communication between the inside and outside of the serious disease by the inner and outer tube of the disease during the fall of the thermos has not been developed yet.

The object of the present invention is to propose a suitable valve device for preventing water leakage during the inversion of a pump-type thermos, which will be described with reference to the embodiment shown in the accompanying drawings. Electric pots, which are indicated by the figure, are roughly divided into a main body unit (2) and a lid unit (3), both of which are driven by the hinge shafts (53) to the rear hinges (51) and (52). Connected and combined. In the outer case 40 of the main body unit 2, a heavy bottle 11 is accommodated, and a lower mouth member 7 is mounted above.

The middle arm 25 fits into the whole blood 16 of the lower mouth member 7. The inner tube 12 and the outer tube 13 are connected to the heavy arm 25, and when the thermos is used, these can be handled integrally. The pump shaft 17 penetrates the middle arm 25 and the inner tube 12.

The lower end of the pump shaft 17 is provided with a pump wing 18 in the vicinity of the absorption port 20 of the inner tube 12. In addition, the upper end of the pump shaft 17 protrudes above the middle arm 25, and a lower clutch 42 engaged with the upper clutch 41 of the motor 5 shaft, which will be described later, is attached.

The motor 5 is built in the lid case 8 of the lid unit 3, and the upper clutch 41 is attached to the motor shaft 15. As shown in FIG. In the central portion of the bottom plate 4 of the lid case 8, a clutch box 47 for inserting the clutches 41 and 42 is formed. The battery serving as the power source of the motor 5 is housed in the battery chamber 6, and the battery can be replaced by opening the upper portion 9. The push button 22 is provided in the upper opening 9, The movable button 21 and the fixed contact 24 are opened and closed by this push button 22, and the electric power supply to the motor 5 is controlled. Next, the structure of the leakage preventing valve device, which is a main part of the present invention, will be described in combination with FIGS. 1 and 2 to form the lower valve case 33 at the liquid outlet portion of the heavy electric field 25 in the illustrated embodiment. On the other hand, the upper valve case 32 is formed at the proximal end of the bottle outer tube 13, and these valve cases 33 and 32 are fitted with detachable materials to form a valve chamber 31, and the valve chamber 31 is provided. The valve holder 26 and the round valve 27 are accommodated inside.

The valve holder 26 has a plurality of passage holes 28, 28... Has a basket-shaped box (49) and a flange (35) formed at the upper end thereof. In this embodiment, the flange (35) is formed at the upper end of the lower valve case (33) and inside the upper valve case. The valve holder 26 is fixed and held between the pressure cylinders 34.

In this embodiment, since the pressing cylinder 34 in the upper valve case 32 serves as a valve seat with respect to the round valve 27, the inner diameter of this pressing cylinder 34 is made smaller than the diameter of the round valve 27. As shown in FIG. Subsequently, the operation of the pump-type thermos 1 shown will be described. First, the liquid unit W is injected into the heavy bottle 11, and the lid unit 3 is opened to extract the heavy warp 25.

After injecting the liquid into the heavy bottle 11, the heavy warp 25 is fitted and the lid unit 3 is closed again. Both units 2 and 3 are locked in engagement with the engagement piece 38 on the (2) side.

The bottom plate 4 of the lid case 8 presses the middle arm 25 from above over the corners 44 and closes the whole blood 16 of the inlet member 7 by the packing 10. At this time, the upper clutch 41 of the motor 5 and the lower clutch 42 on the side of the pump shaft 17 are brought into engagement with each other. When the push button 22 is pressed in this state and the contacts 21 and 24 are closed, the motor 5 rotates as much as that time, and the pump wing 18 is driven across the clutches 41 and 42 so that the liquid W ) Can be sent. The liquid W sucked into the inner tube 12 from the suction port 20 by the rotation of the pump blades 18 is injected into the heavy outlet 25 through the valve chamber 31 and the outer tube tube 13. Is poured out). When the liquid W passes through the valve chamber 31, it passes through the water passage hole 28 of the valve holder 26, so that the existence of the valve holder 26 does not interfere with the liquid injection.

At the time of pump rotation, the liquid tries to leak upward through the shafts 39 formed on the top plate of the heavy electric field 25, but a water rod packing is disposed around the pump shafts 17, The leakage from 39) is prevented.

When the pump-type thermos 1 is accidentally inverted, in general, the spout 30 of the bottle outer tube 13 is downward, but at this time, the round valve 27 in the valve holder 26 is driven by gravity. And the valve seat 29 is closed as indicated by the dashed line 27 '. Therefore, the liquid W in the bottle cannot flow out toward the outer tube 13 and can prevent leakage of the liquid due to the conduction of the thermos 1.

In addition, since the whole blood 16 of the inlet member 7 is sealed by the seal 10 between the shafts 39 of the heavy arm 25, the liquid leakage from these openings can be prevented. will be.

This invention is as described above, the thermos bottle transfer bottle outer view 13 by holding the valve holder 26 by the bottle outer tube 13 and the heavy arm 25 and accommodated in the valve holder 26. Because it closes the liquid passage in), it has the following effects.

That is, according to the present invention, since the leak prevention valve device 14 is installed between the bottle outer tube 13 and the whole body 25, the leak prevention valve device 14 is disposed in the liquid in the bottle when the thermos bottle is not used. Since it is not immersed, even if this leak-proof valve device is made of synthetic resin, it does not deteriorate initially. In addition, in the electric pot, the pump shaft 17 vertically closes the inside of the inner tube 12, so if the leakage preventing valve device is installed in the middle or lower end of the inner tube 12, the structure becomes extremely complicated. With this design, installing a leak prevention valve device 14 between the bottle outer tube 13 and the heavy arm 25 can simplify the structure, improve productivity, and reduce the manufacturing cost of the pump-type thermos, The flow resistance is reduced and the liquid can flow out smoothly.

In addition, as shown in the embodiment of the illustration, if the heavy arm 25 and the outer tube 13 are fitted with a detachable material, they can be separated and cleaned of the valve holder 26 or the round valve 27 as necessary. There is an effect that can be used hygienically pump type thermos. Thus, according to the present invention, according to the practical use of the simple leak-proof valve device for the pump type thermos, so-called electric pot or air pot pump type thermos can prevent the liquid leakage of the whole city, this type of pump thermos Can be used safely and sanitarily.
