Abstract
The utility model discloses a valve type thermos plug, which comprises a plug body and the plug body is a hollow cylinder, wherein, the upper segment of the plug body is larger than the lower segment of the plug body; steps are arranged at the inner side of the juncture of the upper segment and the lower segment so that an inner cavity of which the upper part is big and the lower part is small is formed. The upper end of the plug body is provided with a cover which is provided with outflow holes and air supply holes. The lower end of the plug body is in the opening shape. A spherical body is arranged in the inner cavity arranged at the upper section of the plug body; the diameter of the spherical body is respectively longer than the diameter of an inner circle of the lower segment of the plug body and shorter than the diameter of the inner circle of the upper section of the plug body; distance is reserved between the spherical body and the cover. A circumferential groove is arranged on an outer circle of the lower segment of the plug body and a sealing ring is embedded in the circumferential groove. The valve type bottle plug is used for the thermos plug and also used for a plug for a container which is filled with other liquid. A thermos with the bottle plug is used, which is convenient to pour water or cover bottle plug and avoid appearing the condition that the liner of the thermos breaks for the oversized inner pressure of the thermos.
Description
Technical field
The utility model relates to a kind of bottle stopper.Be the thermal bottle bottle stopper specifically, also can be used as the container stopper of other liquid of splendid attire.
Background technology
At present, used bottle stopper mainly contains two kinds on the thermal bottle.A kind of is cork, and another kind is a plastic plug.Cork had wherein both had the hot water that prevents in the thermal bottle function that turns cold, and had sealing function again.Therefore, adopted by people are extensive for a long time.But in the time the hot water in the thermal bottle need being poured out, must earlier bottle stopper be extracted, and fall behind the water, need are again with the bottleneck of bottle stopper at thermal bottle again.Therefore, pouring is cumbersome.Because this bottle stopper do not have the automatically unloading function, when it being filled in the hot water bottleneck that fills with boiling water, need pay most careful attention to, can not exert oneself too big or speed too fast.Because when stopper is filled in, the hot water in the water bottle can be compressed and press in producing stopper is ejected, and can make the fragmentation of thermal bottle inner bag when serious.
And plastic plug contains a cylindrical shape cock body, in the middle of the inner chamber of this cock body a circumferential step is arranged, and in the cock body on the step rubber valve is arranged.Be with spring on the said rubber valve.Also must be furnished with a bottle cap that is screwed on the bottle when in addition, using this bottle stopper.When bottle cap is screwed on the bottle, rely on the cylinder compression of bottle cap to rubber valve top, rubber valve is moved down and offset with circumferential step (being valve) in the middle of the cock body inner chamber, realize sealing function with this.When the needs pouring screws off bottle cap, rubber valve rely on spring elastic force can on move, at this time if water bottle is tilted, the hot water in the water bottle can flow out from the water outlet at cock body middle part.Because the water outlet of this plastic plug must be in 180 degree places with handle the other side, the hot water in the bottle just can be poured out, and therefore, must aim at during the lid bottle stopper.In addition, this plastic plug only when bottle cap is screwed on the bottle, just can make valve closing.In a word, use the water bottle of this plastic plug, no matter be that pouring or capping plug are all cumbersome.
Summary of the invention
The purpose of this utility model is to provide a kind of valve formula thermos cork.Use the thermal bottle of this bottle stopper, pouring or capping plug are all more convenient, and can avoid making because of the thermal bottle internal pressure is excessive the situation of inner bag fragmentation to take place.
Above-mentioned purpose of the present utility model is realized by following technical solution:
Valve formula thermos cork of the present utility model comprises cock body, is characterized in that cock body is hollow cylindrical shell, and its epimere is greater than hypomere, and there is step the inboard of epimere and hypomere intersection, to form up big and down small inner chamber.There is lid the cock body upper end, and this has covered apopore and induction opening.The cock body lower end is uncovered shape.Cock body epimere inner chamber has globoid, the diameter of this globoid respectively greater than with less than the interior circular diameter of cock body hypomere and the interior circular diameter of cock body epimere, leave distance between itself and lid.On the cylindrical of cock body hypomere circumferential recess is arranged, groove is embedded with seal ring.
Adopt such scheme, have the following advantages:
Because cock body of the present utility model is hollow shape, its epimere is greater than hypomere, and there is step epimere and hypomere intersection inboard.Its epimere inner chamber has globoid, the diameter of this globoid respectively greater than with less than cock body hypomere and epimere intracavity diameter.There is lid the cock body upper end, has covered apopore and induction opening.Under non-pouring situation, globoid is in upper and lower section intersection of cock body and upper and lower section inner chamber of bottle stopper is separated.If press in producing in the thermal bottle, move in the globoid meeting automatically, the pressure in the bottle is leaked, thereby avoided making the situation of inner bag fragmentation to take place because of pressure of the inside of a bottle is excessive.
When bottle stopper tilted with the inclination of thermal bottle, globoid can move in the epimere of cock body along with the increase at bottle stopper angle of inclination, thereby the hot water in the bottle is poured out from the water outlet that covers, and need not pull out bottle stopper and can realize pouring, used more convenient.
Description of drawings
Fig. 1 is a valve formula thermos cork cross-sectional schematic of the present utility model;
Fig. 2 is the schematic top plan view of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, valve formula bottle stopper of the present utility model comprises cock body 4, and this cock body is hollow cylindrical shell, and its epimere diameter is greater than hypomere.Upper and lower section inner chamber intersection at cock body 4 forms a circumferential step, on this circumferential step chamfering arranged.Be placed with a globoid 6 in cock body 4 epimeres, this globoid is a glass bead, also can be with stainless steel ball etc.The diameter of globoid 6 is greater than the interior circular diameter of cock body 4 hypomeres, and less than the interior circular diameter of cock body 4 epimeres.Said cock body 4 epimeres are up big and down small taper shape.The lid 2 that the useful corrosion-resistant steel of the upper end cover of cock body 4 is made, 6 of this lid and globoids leave distance, and apopore 1 and induction opening 3 are arranged on it.Apopore 1 wherein is relative shape with induction opening 3 to be opened in the edge of lid 2, and apopore 1 is greater than induction opening 3.Cock body 4 hypomere excircles are to being processed with a groove, and groove is embedded with the seal ring made from rubber 5.
