Abstract
The utility model relates to a life commodity, in particular to an improvement of air pressure thermos bottle. The utility model is added with a tapered stopper, a soft tube and a floating plate device on a hollow stopper in order to increase the heat-insulating property of common air pressure thermos bottle and reduce the pollution of the boiled water caused by the scale deposit. Therefore, the heat-insulating property of the air pressure thermos bottle is improved, and the scale deposit pollution is reduced.
Description
The utility model relates to small stores, especially the improvement of air pot.
Normally used air pot by cap seat (1), housing unit (2), aqueduct (3), glass liner (4), hollow plug (5), calm the anger speak in a low voice (15), bottle cap (16), gland (17) form, it exists two significant disadvantages:
(1), the air inlet (13) (referring to Fig. 1) that has hollow plug (a 9) upper end of outlet pipe is to be communicated with the pressuring gasbag (15) on top and the glass liner (4) of following storage boiling water.At ordinary times, the vapours in the glass liner arrives outside the bottle, so the heat-insulating property of air pot is poor than ordinary thermos bottle by the gap spill and leakage between pressuring gasbag (15) and bottle cap (16) and the gland (17) along this mouth.
(2), in the hole (14) of hollow plug (9), usually insert an aqueduct that extends to glass liner (4) bottom, when so each pump air pressure goes out boiling water, taking some incrustation scales (8) that are deposited in glass liner (4) bottom always out of comes, edible this boiling water is harmful, particularly in hard water areas, this disadvantage is just more obvious.
The air pot of China's production at present is basic identical with the product structure principle in Japan and Taiwan, also all exists this two shortcomings.
For the heat-insulating property and the pollution of minimizing incrustation scale to boiling water that improve common air pot, the end opening place of the air inlet (13) of the utility model on the hollow plug (9) of common air pot has increased conical plug (10), flexure strip (11) and has covered (12) (as shown in Figure 1).The seam of lid (12) is buckled on the hollow plug (9), pushes down flexure strip (11) on it.Conical plug (10) is withstood in the upper end of flexure strip (11), and the tapering face of conical plug clogs air inlet (13).Like this, the vapours in the glass liner (4) just can not have been overflow outside bottle at ordinary times, has increased the heat-insulating property of vacuum flask.When pushing gland (17) with hand, the air in the air bag (15) is by air inlet (13), pushes conical plug (10) open and enters into glass liner (4), makes boiling water in the glass liner be subjected to the pressure of air.
The utility model changes former hollow plug (9) lower end, straight cutting of being contained in into corrugated hose (3) to the aqueduct of glass liner (4) bottom again, and the lower end side of pipe has water inlet (7), mouthful top floating plate (5) is housed.The boiling water that is under pressure enters water inlet (7), through the outlet pipe outflow boiling water of aqueduct (3), hollow plug (9).Because the water inlet (7) of aqueduct (3) is in the bottom of floating plate (5), floating plate (5) floats on the boiling water face, so each boiling water that extrudes all is the boiling water of glass liner mesexine, the incrustation scale (8) that can not take glass liner (4) bottom out of comes.The suitable length of configuration pipe (3), the height in the time of can adjusting floating plate (5) and drop to glass liner (4) bottom is advisable with unlikely derivation incrustation scale.
Adopt the air pot of the utility model production to increase heat-insulating property, reduced the pollution of incrustation scale and sediment boiling water.On existing production line, need not do big change and many investments.
Fig. 1 is the utility model---the structure chart of harmless air pot.
Fig. 2 is the enlarged drawing of floating plate among Fig. 1 (5).
When adopting the utility model, flexible pipe (3), floating plate (5), conical plug (10), flexure strip (11) and lid (12) are all made with nontoxic, resistant to elevated temperatures soft material. The inside of floating plate (5) can be filled with air, and also available soft material is filled, and should fill in from glass liner (4) oral area easily after making and pull out.
Claims (2)
1, air pot, form by cap seat (1), housing unit (2), aqueduct (3), glass liner (4), hollow plug (5), pressuring gasbag (15), bottle cap (16), gland (17), the feature of the harmless air pot of the utility model is: (A) on the under shed of the air inlet that has the hollow plug of outlet pipe (9) (13), increase a conical plug (10), flexure strip (11) and lid (12).Conical plug (10) clogs the air inlet (13) of hollow plug (9), and flexure strip (11) withstands conical plug (10), lid (12) is pushed down flexure strip (11).(B) aqueduct (3) of dress changes a spirality flexible pipe (3) in the following stomidium (14) of hollow plug (9).(3) lower end side has water inlet (7), and floating plate (5) is equipped with in the upper end of water inlet (7).
2, harmless air pot according to claim 1 is characterized in that: flexible pipe (3), floating plate (5) conical plug (10), flexure strip (11), lid (12) are all made with nontoxic, resistant to elevated temperatures soft material.
