Abstract
The utility model relates to a pressure-generating stopper for a bottle, comprising an air bag (1), the frame (4) of the bottle stopper, a water inlet pipe (7), and a discharging tube (8), characterized in that a ring flanging at the bottom of the air bag (1) is tightly clamped on the frame (4) of the bottle stopper via the cover (4) of the bottle stopper. The cover (3) of the bottle stopper is in the screw connection with the frame (4) of the bottle stopper. The utility model overcomes the defects that after the prior the air bag of the pressure-generating stopper for the bottle is stuck with the frame (4) of the bottle stopper, the crack and air leakage are easy to generate and the repair is impossible for making the whole body fail. One element is changed for making the complete set of the bottle stopper continuously use, and the damage of one element can not make the complete set of the bottle stopper fail. The utility model has the advantages of easy processing, long service life, easy repair, and convenience.
Description
The utility model belongs to the vapour-pressure type bottle stopper of thermos bottle.
Have now in the used vapour-pressure type bottle stopper of thermos bottle, the bottom of its air bag of CN2057836U disclosed " Air pot plug " is to adopt glue to be bonded on the Bottle stopper body, owing to often be subjected to external force and action of high temperature, therefore will soon come unstuck and leak gas, both can't use, be difficult to repair, life-span is short, manufacturing cost height again, price is expensive, and the consumer is difficult to bear.Its air pressure generator of CN2065040U disclosed " a kind of thermos bottle air pressure water intaking plug " is that to be bonded in service time one on the gas transmission transition conduit long or using method is improper, gas and break at the air pressure generator root will be left out, both can't use, be difficult to again repair, have to whole bottle stopper is scrapped, improved use cost.
The purpose of this utility model provides and a kind ofly both had been easy to processing and manufacturing and had been easy to repair, long service life again, practical and convenient Pressure-generating plug for bottle.
The technical solution of the utility model is: improve for the Pressure-generating plug for bottle with air bag, bottle stopper frame, water inlet pipe and outlet pipe, make that flange is clamped on the bottle stopper frame by bottle stopper under the annular of air bag bottom, and bottle stopper is threaded with the bottle stopper frame.
Good airproof performance, difficult loosening Pressure-generating plug for bottle when further purpose of the present utility model is a kind of and the load of water bottle bottleneck are provided.
Realize that the technical scheme that above-mentioned further purpose adopts is: be with elastic ring in the piston part of bottle stopper frame and the bottom has annular shoulder block.
The utility model is owing to adopting a bottle stopper to be threaded with the bottle stopper frame and clamping the annular flanging of air bag bottom with this, therefore, both without glue, avoided the drawback of leaking gas because of coming unstuck, be convenient to place under repair when damaging again, just can continue to use as long as change a whole set of bottle stopper of parts (generally speaking as long as change an air bag), not parts damages of reason and scrapping.After being with elastic ring on the bottle stopper frame, make sealing raising between bottle stopper frame and the bottleneck, be difficult for loosening.The utility model not only is easy to make, and practical and convenient, and long service life is economical and practical, is subject to the consumer and welcomes.
The embodiment that provides below in conjunction with accompanying drawing is further described specifically structure of the present utility model.
As shown in the figure, the utility model Pressure-generating plug for bottle has air bag (1), bottle stopper frame (4), water inlet pipe (7) and outlet pipe (8), the annular flanging (2) that is characterised in that air bag (1) bottom is clamped on the bottle stopper frame (4) by bottle stopper (3), and bottle stopper (3) is threaded with bottle stopper frame (4).Bottle stopper (3) is an internal thread, and bottle stopper frame (4) is an external screw thread.The piston part of bottle stopper frame (4) is with elastic ring (5) and the bottom has annular shoulder block (6), and the effect of annular shoulder block (6) is to hold elastic ring (5) its unlikely piston part from bottle stopper frame (4) is come off.
Among the figure, air bag (1) is the tubular of falling the bellows, and bottle stopper (3) has just played the gastight effect of sealing after clamping air bag (1) base circle flanging (2) and be tightened in bottle stopper frame (4) and going up.During manufacturing, air bag (1) can adopt heat-resisting nontoxic rubber or elastoplast to make, bottle stopper (3) and bottle stopper frame (4) can adopt heat-resisting nontoxic hard moulding material to make, elastic ring (5) can adopt heat-resisting nontoxic elastic material to make, and water inlet pipe (7) and outlet pipe (8) can adopt heat-resisting non-toxic material to make.
The utility model in use, the elastic ring (5) that bottle stopper frame (4) piston part is overlapped can with the sealing of fitting of thermos bottle bottleneck, increase frictional force and improve stability.Water inlet pipe (7) gos deep in the interior hot water of the glass liner of a thermos flask.When press pressuring gasbag (1) with hand, the air pressurized in the air bag (1) is also oppressed the interior hot water surface of glass liner, and hot water is risen and outflow from outlet pipe (8) along water inlet pipe (7).Unclamp air bag (1), then the glass liner inner air pressure is less than outside atmospheric pressure, and outside air then enters in the glass liner along outlet pipe (8) and water inlet pipe (7), makes the inside and outside air pressure of glass liner keep balance.So repeatedly, can use continuously.
Above-mentioned bottle stopper frame (4) also can be to drive a cannelure in the piston part, again annular resilient collar is put into cannelure, but the external diameter of annular resilient collar need be slightly larger than the external diameter of piston part, just can make annular resilient collar play sealing function after putting into the hot water bottleneck.
Claims (2)
1, a kind of Pressure-generating plug for bottle, have air bag (1), bottle stopper frame (4), water inlet pipe (7) and outlet pipe (8), it is characterized in that: the annular flanging (2) of air bag (1) bottom is clamped on the bottle stopper frame (4) by bottle stopper (3), and bottle stopper (3) is threaded with bottle stopper frame (4).
2, Pressure-generating plug for bottle according to claim 1 is characterized in that: the piston part of bottle stopper frame (4) is with elastic ring (5) and the bottom has annular shoulder block (6).
