Description
Technical field
The present invention relates to the suction hose of consumer goods industries, more particularly to a kind of plug-in type anti-return suction pipe and container,
Applied to Hydraulic Field, the various container for using suction hose is widely applied.
Background technique
Disposable container drinking water has deeply been spread to during we live, while being provided people and being drunk and go on a journey safely band
To facilitate.But people make the saliva and swill in oral cavity when drinking water bottle due to generating negative pressure
It flows back into the bottle that do not drunk, microorganism breeds rapidly, so unfavorable to health when people drink again.There is fraction at present
Brand devises squash type drinking-water lid in cup lid, but in the duct due to its soft seal water valve design, still has section of tubing to exist
In range of circulating flow, valve port is generally cross mouth, and such design cannot obstruct reflux completely, still has partial reflux to pipeline
In, and because there is no air return system, so that forming high negative pressure during sucking in bottle, it is bigger to stop the moment sucking generation
Reflux, and the drinking-water lid of this squash type manufactures complexity, high production cost is disposable to bring waste.
In view of defect existing for above-mentioned existing suction hose, the present inventor passes through continuous research, design, and through repeatedly
After studying sample and improving, the present invention having practical value is created finally.
Summary of the invention
It is an object of the present invention to overcome the defects of existing, and a kind of a kind of new structural plug-in type is provided and is prevented back
Suction pipe and container are flowed, the technical problem to be solved is that its effective anti-backflow is made, prevents saliva and swill from flowing back, protects
Healthy water is demonstrate,proved, to be more suitable practical application.
Another object of the present invention is to provide a kind of plug-in type anti-return suction pipe and container, make its more convenient drinking-water,
It can squeeze and drink, head can be faced upward and drunk, can bow and drink, can be drunk with recumbency, it is safe and convenient.
Another object of the present invention is, even if accidentally knocking water bottle over, water, which will not spill, to be come, safe ready.
The object of the invention to solve the technical problems adopts the following technical solutions to realize.It proposes according to the present invention
A kind of plug-in type anti-return suction pipe, be made of elastic sucker head, soft suction pipe, the upper end of soft suction pipe and elastic sucker head 1
Connection, wherein the top of the elastic sucker head is equipped with duckbill anti-reflux valve, the duckbill anti-reflux valve is
The duckbill anti-reflux valve of inverted V-shape or half arc is collectively constituted by two panels valve block, the two panels valve block fitting makes elastic suction
Tube head 1 topmost forms 1-shaped open shape, which does not have any groove to form water space, when sucking,
One word opening opens water outflow, and when stopping sucking, the word opening moment due to resilience of elastic material is closed, completely isolated
Liquid reflux in oral cavity.
A kind of plug-in type anti-return suction pipe above-mentioned, wherein the angle of two valve blocks of the elastic sucker head be 2 °-
179°。
A kind of plug-in type anti-return suction pipe above-mentioned, wherein elastic sucker head further includes resilient plug, and the resilient plug is set
In the lower part of elastic sucker head, which, at fitting closely, not only seals container but also makes elastic sucker head with vessel port inner wall
It is not easily to fall off.
A kind of plug-in type anti-return suction pipe above-mentioned, wherein the resilient plug includes anti-overflow diversion canal, described is anti-overflow
The one side of resilient plug is arranged in diversion canal, when pushed, the air in container is discharged, space is formed in container when preventing from pressing
Pressure and make liquid spill.
A kind of plug-in type anti-return suction pipe above-mentioned, wherein the resilient plug further includes return-air valve, the return-air valve is set
The another side of resilient plug is set, which is check valve, when sucking, negative pressure is formed in container, air can pass through return-air valve
Into bottle body, and negative pressure in equalizing reservoir, also play the role of continuously sucking not flatulence, it is ensured that suck more unobstructed.
A kind of plug-in type anti-return suction pipe above-mentioned further includes suction pipe storage lid, and the soft suction pipe lower part can be bent
Disk turns to facilitate storage in suction pipe storage lid and carry.
A kind of plug-in type anti-return suction pipe above-mentioned, further includes adapter of plastic, and the upper end of the soft suction pipe passes through modeling
Material connector is connect with the bottom of elastic sucker head.
A kind of preceding plug-in type anti-return suction pipe further includes plastics fixing sleeve, dustproof cover and opens key, described
The resilient plug of the upper end connection of the plastics fixing sleeve elastic sucker head, the lower end connected sucking pipe of plastics fixing sleeve store lid,
Dustproof cover is housed, the other side of plastics fixing sleeve is equipped with unlatching key on plastics fixing sleeve side.
A kind of plug-in type anti-return suction pipe above-mentioned, wherein the overall diameter of the resilient plug is true according to the diameter of vessel port
It is fixed.
A kind of plug-in type anti-return suction pipe is used to absorb the container of liquid.
The present invention has obvious advantages and beneficial effects compared with the existing technology.It at least has the advantage that
1. the present invention is to be designed to duckbill in the top of suction pipe using suction pipe made of elastic material, the two of duckbilled
Half one-way valve designs being open in a word, recycle the resilient plug of suction pipe bottom and bottle body to stopper to form water shutoff headkerchief, and in bullet
Property design one or more return-air valve (for negative pressure in equilibration flask) beyond the Great Wall, when people are during sucking, a word duckbill is prevented back
Stream valve is open at once, makes in water in bottle suction inlet, when stopping sucking, the one word valve body of principle of anti-reflux valve elastic material reset
It can be momentarily turned off, prevent liquid reflux in mouth, since duckbilled anti-reflux valve is the naked dew design designed in suction pipe top, valve
Door does not have any withdrawing fluid to ensconce in suction pipe when closing, thus the water reflux being effectively isolated in mouth.
2, the bottom of elastic sucker head of the present invention is equipped with resilient plug 1-2 and makes between elastic sucker head and vessel port, Ke Yifang
Using in such a way that plug is chosen just, mainly utilizes the elasticity of " resilient plug 1-2 " to fit closely with the formation of vessel port inner wall,
It seals and to be able to achieve close-fitting not easily to fall off.Not only it had sealed container but also had made the tight fit of elastic sucker head and container,
It is not easily to fall off.
3, when elastic sucker head presses, the confined space in container can be allowed to form pressure, and makes the liquid spill in container,
So the present invention is being equipped with " anti-overflow exhaust slot " (as shown in Figure 4) on resilient plug, it will be in container when its role is to press
Air discharge, container is excessive when preventing from pressing.
4. the present invention uses when return-air valve because return-air valve balances negative pressure in bottle, suck-back phenomenon will not be generated, and to inhale
It suckes more easily unobstructed.
5. the present invention due to being connected with elastic sucker, can both face upward head and drink, bow and drink, squeeze to drink and a variety of drink method.
6. people accidentally touch container in use, also because there is the design of closed type suction pipe not outflow.
7. the present invention is adapted to various containers, the scope of application is extremely wide.
The above description is only an overview of the technical scheme of the present invention, in order to better understand the technical means of the present invention,
And it can be implemented in accordance with the contents of the specification, and in order to allow above and other objects, features and advantages of the invention can
