Description
Technical field
This utility model relates to infant article field, is specifically related to a kind of feeding bottle air inlet valve.
Background technology
We know, feeding bottle is a kind of utensil of containing milk, for for infant diet.Existing feeding bottle generally comprises bottle, plastic fastening, silica gel nipple and dust cap.For ensureing the smooth feed of milk, generally on silica gel nipple, be provided with air inlet, its operation principle is that the elastic material of silica gel nipple opens air inlet and is able to air inlet when milk pressure of the inside of a bottle is during lower than atmospheric pressure.The air intake structure of this kind of feeding bottle easily causes the situation of milk adverse current seepage, has certain potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is for above the deficiencies in the prior art, and a kind of feeding bottle air inlet valve is provided, and this feeding bottle air inlet valve is easy for installation, after installation, make feeding bottle non-leakage, use safety.
For addressing the above problem, this utility model provides a kind of feeding bottle air inlet valve, this feeding bottle air inlet valve comprises annular base, the friction tight cylindrical seal plug of through hole of the inner hollow that flexible material is made and outer wall and prepackage feeding bottle bottom, the first valve, the top of described the first valve is provided with in the time that feeding bottle air pressure inside is less than atmospheric pressure and opens, and the air inlet of closing in the time that feeding bottle air pressure inside equals atmospheric pressure, the bottom of described sealing-plug is connected with annular base, and the interior bone of sealing-plug (inner hollow formation through hole) communicates with the inner circular aperture of annular base, the top of described sealing-plug is connected with the bottom of the first valve.
Adopt after above structure, this utility model compared with prior art, have the following advantages: this utility model arranges special intake valve for feeding bottle air inlet, sealing-plug sealing-plug is in feeding bottle bottle body bottom, when baby tilts feeding bottle when having milk, this intake valve is positioned at i.e. top, feeding bottle bottom, do not contact with milk, contact with air in bottle, and because air inlet directly contacts with air, air inlet is more smooth and easy, and this makes baby's milk of taking food more laborsaving.
As preferably, described the first valve is conical valve, and the vertical dimension that the external diameter of described the first valve bottom is greater than between external diameter and the first valve and the annular base of sealing-plug is greater than the height of pre-installing feeding bottle bottom through-hole.Adopt this structure, intake valve is just not easy after being filled in the through hole of feeding bottle bottom, ensures to use safety.
As preferably, the both sides of described conical the first valve are two (a pair of) flat thin film that be oppositely arranged and top contact (formation air inlet) along tapering, and wherein the thickness of thin film is 0.1-1.2mm, is preferably 0.5mm.
As preferably, described base, sealing-plug, the first valve are one-body molded by silica gel material.Silica gel material sealing property is better, and conveniently fills in and deviate from; Integrated sound construction, durable in use, and more easy cleaning, be difficult for accumulation dirt, health more.
As preferably, this utility model feeding bottle air inlet valve also comprises the second air intake assembly, described the second air intake assembly comprises the hollow plug, the second valve that tightly fit in sealing-plug endoporus (inner hollow formation endoporus), the top of described the second valve is provided with the air inlet of opening in the time that feeding bottle air pressure inside is less than atmospheric pressure and closing in the time that feeding bottle air pressure inside equals atmospheric pressure, the top of described hollow plug is connected with the bottom of the second valve, between described the second valve and the first valve, is cavity.The setting of the second air intake assembly to this feeding bottle air inlet valve many again one protective barrier, main manifestations is: (1) is just in case the air inlet seepage of milk from the first valve, milk enters the cavity between the second valve and the first valve, and does not directly leak into outside feeding bottle; (2) because intake valve is positioned at bottle body bottom, easily be stained with dirt, by arranging above after double-deck intake valve, what dirt touched is the second valve, middle across cavity, can never encounter the first valve that contacts contact with milk, ensure that milk is not polluted by external dirt, use safer; (3) structure of double-deck intake valve is conducive to increase the service life, just in case one of them intake valve damages, has the existence of another intake valve, can also make this feeding bottle air inlet valve continue to play a role.
As preferably, described the second valve is conical valve, and the bottom of this taper shape valve is connected in sealing-plug; The external bottom end of described hollow plug is one-body molded the round ring boss that is connected in base, and the bottom of described round ring boss flushes with the bottom of annular base.It is more firm that the structure of above clamping makes hollow plug be connected with sealing-plug, and more difficult drop-off also uses safer.
As preferably, described conical the second valve both sides are two (a pair of) flat thin film that be oppositely arranged and top contact along tapering, and wherein the thickness of thin film is 0.1-1.2mm, is preferably 0.5mm.
As preferably, described hollow plug, the second elastic cone film are one-body molded by silica gel material.Integrated sound construction, durable in use, and more easy cleaning, be difficult for accumulation dirt, health more.
