Background technique
With the development of society, the material life of people has obtained greatly enriching, people not only chase after product quality
It asks, also to the packaging of the appearance packaging of product especially daily necessities, higher requirements are also raised.Its appearance packaging is not single
It is singly simple container, it is necessary to the convenience taking into account beautiful moulding and using.Squash type or the Packaging Bottle of push type discharging
It is the convenience that is used due to it, handsome in appearance and show one's talent in the packaging of daily necessities.
Patent CN105923281A discloses a kind of self-priming pumping pressure type packaging bottle, and it discloses the dischargings of general push type to pack
The discharging principle of bottle, lotion close discharge nozzle upper end outlet from after discharge nozzle extrusion, through pressing piece, and lotion is hung in discharge nozzle
Wall blocks discharge nozzle and forms vacuum, the smooth extrusion of lotion when reusing to facilitate, as lotion can not cannot achieve if wall built-up
Sealing, will appear disconnected cream, can not normally discharge when reusing.The pump head of the Packaging Bottle of the push type discharging of the prior art is all only
It is a simple discharge nozzle, low in cost although structure is simple, when release key closes Packaging Bottle, lotion is in gravity
Under the action of can flow down, with the extension of use time, the sealing of discharge nozzle lower part is gradually failed, and lotion cannot be protected completely
It holds in discharge nozzle, needs repeatedly pressing just to can guarantee extrusion lotion when in use, seriously affected the using effect of Packaging Bottle.
Therefore, a kind of great reality meaning of the elastomeric style toothpaste pump that lotion can be stopped to flow back and enhance sealing effect is developed
Justice.
Summary of the invention
Present invention aim to address problems of the existing technology, provide a kind of elastomeric style toothpaste pump.
In order to achieve the above objectives, the scheme that the present invention uses is as follows:
Elastomeric style toothpaste pump, including key, discharge nozzle and seal receptacle further include that elastomer is (i.e. whole by elastic material
Manufactured component), discharge barrel, upper check valve and lower check valve；

In middle cylinder, the upper end of the two is flushed, and is connected with each other by the first connection ring, and the lower end of middle cylinder and the small end of umbrella body connect
It connects, small end, that is, lesser one end of umbrella body size of umbrella body, settable a plurality of card rib around the small end of umbrella body, to improve umbrella body
Structural strength；
Discharge barrel is only open at one end, between the inner cylinder and middle cylinder of the open end insertion elastomer of discharge barrel, discharge barrel and bullet
Property body be fixedly connected, the closed end of discharge barrel is equipped with material through hole；
Key is located at the top of elastomer, for driving elastomer to move downward；Discharge nozzle is inserted into the inner cylinder of elastomer,
The cooperation of the two interference seal；Seal receptacle is located at the lower section of discharge barrel, and which is provided with feed-throughs；
Upper check valve is mounted on the material through hole out of discharge barrel, for two sides above and below the closed end of unilaterally connected discharge barrel
Space；Lower check valve is mounted on the feed-throughs of seal receptacle, the space for two sides above and below unilaterally connected seal receptacle；All
Unilaterally connected all refers to that filler can only flow from bottom to top.
The action process of elastomeric style toothpaste pump of the invention are as follows: under natural conditions, upper check valve and lower closed check valve,
The nozzle of discharge nozzle and the material through hole that goes out of discharge barrel are sealed by upper check valve, and the feed-throughs of seal receptacle are sealed by lower check valve；
When applying downward active force to key, elastomer deforms under the action of key, drives discharge barrel to move downward, out
Expects pipe nozzle is opened, and the space pressure between discharge barrel and seal receptacle increases, and upper check valve is opened, between discharge barrel and seal receptacle
Filler from discharge barrel go out material through hole squeeze out, enter in discharge nozzle via the cavity that discharge nozzle and discharge barrel surround, from go out
It is squeezed out in expects pipe, in the process, the feed-throughs of seal receptacle are sealed by lower check valve always；When removal is to the active force of key
When, elastomer restores deformation, and drive discharge barrel to move upwards, while key resets, the nozzle of discharge nozzle and upper closed check valve,
Space pressure between discharge barrel and seal receptacle reduces, lower check valve is opened, the filler below seal receptacle from seal receptacle into
Material through hole squeezes out, into the space between discharge barrel and seal receptacle, until placing an order when the space pressure of two sides is equal above and below seal receptacle
It is closed to valve.
