Description
The invention belongs to the field of commodity, is the stopper of using on a kind of vacuum flask
The plug for vacuum bottle of using in the daily life generally all is the conical plugs that adopt cork to make.This stopper deficiency in use is: during the outside pouring of vacuum flask, must take away stopper with hand, and then beyond the Great Wall, make troubles to the user; Owing to take stopper through hand commonly used, make stopper surface gather dust and dirt, stopper soaks at the mouth of a river, and is also very perishable, easily falls to going up dust and dirt on the bottleneck, during pouring, will pour in the water, extremely unhygienic; The back thermal conductivity factor is big because cork is immersed in water, and rapid heat dissipation makes the vacuum flask heat insulation effect relatively poor.Though this plug for vacuum bottle has above-mentioned deficiency, continued to use the age for a long time, there is not better products to replace.I had once applied for the patent of " a kind of hot water thermal insulating bottle stopper of energy automatic switch " (93232595.5) in 93 years, this stopper can reach automatic switch, but still there are many deficiencies in it: outwards during pouring, motion stops drops on the front of current, has hindered flowing of water, current are not concentrated, two current appear sometimes, make it can't be in container pouring, the current size is wayward, inhale on fixed cover unexpected sometimes breakdown sometimes; Motion stops is very easily following when pouring.Dustproof effect is also bad, still has dirt and pours in the water.Therefore, this stopper can not be promoted the use of.
The objective of the invention is, redesign a kind of plug for vacuum bottle that can automatic open close, use plug for vacuum bottle of the present invention, outwards during pouring, do not need to take away stopper, the vacuum flask angle stopper that tilts opens a mouth automatically, water can flow out outside bottle in mouth, and can control the size of current output according to the size at bottle angle of inclination, with vacuum flask when upright, but the stopper bales catch is on the insulation bottleneck, dust can't be entered, and the current of pouring out are concentrated, and motion stops is difficult for dropping out.Have easy to use, do not pollute bottle stopper, increase the vacuum flask heat insulation effect.
Technical scheme of the present invention is: the mobile that it has fixed cover 5 and matches with fixed cover 5.Mobile comprises: loam cake 2, inner chamber 1, dust cover 9 and counterweight guide rod 8.A loam cake 2 is arranged in the mobile, and there is an inner chamber 1 that insulation material is housed loam cake 2 lower ends, and in the bottom of inner chamber 1 counterweight guide rod 8 are arranged, and in the junction of inner chamber 1 and counterweight guide rod 8, dust cover 9 are installed.Dust cover 9 also can be made of one with loam cake 2.Have on the dust cover 9 diameter greater than the water proof of fixed cover 5 along 10, also have the platform 3 with respect to dust cover 9 horizontal directions downward protrusion of a diameter on the dust cover 9 greater than fixed cover 5, counterweight guide rod 8 is provided with boss 7, boss 7 is located at the position on the guide rod 8, when pouring, with the platform 3 internal diameter touching positions that protrude in the top external diameter of fixed cover 5 and the mobile is the center of circle, rotate an angle, between fixed cover 5 and dust cover, just open an openning, water just flows out thereupon, and the top of boss 7 is the maximum open amount when touching mutually with the bottom of fixed cover 5, and at this moment mobile is firmly not in fixed cover, even stand upside down, mobile is dropped out.When vacuum flask was upright, dust cover 9 was buckled in again on the fixed cover 5, played good dustproof effect.Counterweight guide rod 8 can make plastics or other easy-formation material is made cylinder or taper is hollow, interior assembling heavy material 11, and the boss 7 on the counterweight guide rod 8 can be made multiple tooth shape 13.Be hooked in the lower end of fixed cover 5.The platform 3 that protrudes can be made the structure 12 that is provided with several grooves.
Description of drawings: accompanying drawing 1 is the structural representation of one of embodiment of the present invention, and accompanying drawing 2 is user mode figure of accompanying drawing 1.Accompanying drawing 3 is structural representations of two of embodiment of the present invention, and accompanying drawing 4 is user mode figure of accompanying drawing 3, and accompanying drawing 5 is structural representations that one embodiment of the present invention is amplified.Accompanying drawing 6 is structural representations of embodiment of the present invention two, and accompanying drawing 7 is structural representations of four of embodiment of the present invention.
The contrast accompanying drawing elaborates to embodiment of the present invention:
Stopper of the present invention has two parts, and the one, standing part, the one, movable part.Standing part is installed in the insulation bottleneck.The mobile that structure of the present invention has fixed cover 5 and matches with fixed cover 5, the structure of mobile comprises: loam cake 2, inner chamber 1, dust cover 9 and counterweight guide rod 8.Have the lower end of loam cake 2, loam cake 2 that an inner chamber 1 that insulation material is housed is arranged in the mobile, in the bottom of inner chamber 1 counterweight guide rod 8 is arranged, counterweight guide rod 8 can make hollow, in weight material 11 is housed.In the junction of inner chamber 1 and counterweight guide rod 8, dust cover 9 is installed, the part of dust cover 9 matches with inner chamber 1, and a part matches with counterweight guide rod 8.The upper end of dust cover 9 have a diameter greater than the water proof of fixed cover 5 along 10, its effect is to prevent that when pouring water from flowing on the loam cake 2, also has a diameter on the dust cover 9 greater than platform 3 fixed cover 5, that protrude with respect to dust cover 9 horizontal directions downwards, the platform 3 and the water proof of this protrusion are made of one along 10, the effect of the platform 3 that protrudes is: when bottle stopper is opened, the platform 3 that protrudes hangs on the top external diameter of fixed cover (5), make mobile when vacuum flask tilts, can not drop on the front of current, hinder flowing of water.Counterweight guide rod 8 is provided with boss 7, boss 7 is located at the position on the guide rod 8, its effect is when vacuum flask tilts to certain angle, and boss 7 will lean against the bottom of fixed cover 5, can block mobile and not deviate from fixed cover 5, when pouring, with the top external diameter of fixed cover 5 and the platform 3 internal diameter touching positions of protrusion is the center of circle, and the rotary moveable body is when touch mutually with the bottom of fixed cover 5 on the top of boss 7, this position, the maximum open amount when being the stopper unlatching.At this moment mobile is firmly not in fixed cover.Embodiment shown in the accompanying drawing 5 mainly illustrates dust cover to be buckled in the enlarged drawing of fixed cover state and each parts.Embodiment shown in the accompanying drawing 6 is, platform 3 is made on the boss 7 on several grooves 12 and the counterweight guide rod 8 has several profiles of tooth 13, dust cover 9 to be one with loam cake 2.Embodiment shown in the accompanying drawing 7 is, counterweight guide rod 8 is tapers, adds weight material 11 in the awl, and dust cover 9 is an one with loam cake 2.Bottle stopper of the present invention all can adopt high-temperature resistance plastice or synthetic material to make.4 is sealing gaskets among the figure, the 6th, and vacuum flask.
Plug for vacuum bottle of the present invention has easy to usely, does not pollute bottleneck, increases The advantage of heat insulation effect is used bottle stopper of the present invention, during outside pouring, does not need Take away stopper, with angle of vacuum flask inclination, water can outwards flow out automatically, and Can control the size of current output according to the size at the angle of inclination of bottle, will When vacuum flask is upright, but the stopper bales catch is being incubated on the bottleneck water collection of pouring out In, mobile never breaks away from fixed cover, even vacuum flask stands upside down, mobile is not yet Can break away from fixed cover.
