Abstract

The utility model discloses check (non-return) valve is had in a kind of tube body, check (non-return) valve includes being fabricated from a flexible material and elastic closure plate, it is pressed closer between closure plate or mutually between closure plate and inboard wall of tube body and the end mutually pushed is downwardly projecting, form gap at the cooperation of closure plate end.The non-return suction pipe can prevent the liquid below the check (non-return) valve of suction pipe from entering suction pipe upper end when suction pipe upper end is not by certain suction, especially the better effect when fluid temperature is higher.

Description

Non-return suction pipe

Technical field

The utility model relates to a kind of non-return suction pipe, the non-return suction pipe and the various containers for filling supping are mating, use It is used in sucking, is particularly suitable for feeding bottle and infant's water bottle.

Background technique

Conventional suction pipe is exactly the small hose with interior sucker, and the liquid configured in the container of this suction pipe is toppled in container Shi Rongyi pour out or container in fluid temperature it is higher when, liquid is influenced to be easy to overflow along suction pipe by air pressure, holds Easily scald people.

Utility model content

The technical problem to be solved by the utility model is to provide a kind of non-return suction pipe, which can prevent non-return Liquid below suction pipe spills into suction pipe upper end when non-return suction pipe upper end is not by suction.

For this purpose, non-return suction pipe provided by the utility model, including tube body, tube body is generally oval, with only in tube body Inverse valve, check (non-return) valve include being fabricated from a flexible material and elastic closure plate, between closure plate or closure plate and inboard wall of tube body Between mutually press closer and the end that mutually pushes is downwardly projecting, gap is formed at the cooperation of closure plate end, gap is not by external force Piece is closed when effect under the action of elastic force to close to stop the liquid of suction pipe lower part to reach suction pipe upper end by check (non-return) valve, The liquid of suction pipe lower part reaches suction pipe upper end by check (non-return) valve when the suction pipe upper end is by suction.

The technical effect of the utility model: the non-return suction pipe can prevent suction pipe when suction pipe upper end is not by certain suction Liquid below check (non-return) valve enters suction pipe upper end, especially when fluid temperature is higher, slightly expands after closure plate heating, Neng Gougeng Add close closed gap, makes non-return effect better effect.

Specific embodiment

With reference to the accompanying drawings and embodiments, the present invention will be further described in detail, described in it is specific real It applies example to be only used to explain the utility model, is not used to limit the utility model.

Referring to Fig.1, shown in Fig. 2, Fig. 3, the first embodiment of the utility model provide non-return suction pipe, the non-return suction pipe with The various containers for filling supping are mating, use for sucking, are particularly suitable for feeding bottle and infant's water bottle, non-return suction pipe includes Tube body 1, has check (non-return) valve in tube body 1, and check (non-return) valve includes being fabricated from a flexible material and elastic closure plate 2, closure plate 2 it Between or 1 inner wall of closure plate 2 and tube body between mutually press closer and the end that mutually pushes is downwardly projecting, at 2 end cooperation of closure plate Formed gap 3, gap 3 when not by external force in elastic force under the action of be closed piece 2 closing to stop suction pipe lower part Liquid reaches suction pipe upper end by check (non-return) valve, and the liquid of suction pipe lower part is reached by check (non-return) valve when the suction pipe upper end is by suction Suction pipe upper end.Check (non-return) valve includes that three valve flexible materials are made and elastic closure plate 2 in the present embodiment, three closure plates 2 Mutually press closer and the end mutually pushed be downwardly projecting, it is this mutually press closer and downwardly projecting structure can be subjected to lower section it is larger Air pressure or hydraulic without opening, can further promote safety and anti-overflow performance, be formed at the cooperation of three closure plates 2 Gap 3, the gap 3 that three pieces closure plate 2 is formed are in Y-shaped, and the tube body 1 and closure plate 2 are integrally formed and are made of silica gel.

It is shown in reference picture 1, Fig. 2, on the basis of the first above-mentioned embodiment, in order to adjust outer gas in the containers such as feeding bottle It presses, transverse bar 4 made of resilient material is set beside the tube body 1,4 end of transverse bar is provided with gas nozzle 5, and gas nozzle 5 has Link up the air hole 6 of upper and lower ends.In the present embodiment, the gas nozzle 5 is in the cone to stand upside down, and the air hole 6 in gas nozzle 5 is in The cone of handstand, gas nozzle 5 can be set below the bottle cap of container for linking up container inner and outer air pressure.

Referring to shown in Fig. 4, the check (non-return) valve that second of embodiment of the utility model provides includes two panels closure plate 2, a closing Piece 2 is forwardly convex, and another closure plate 2 is recessed backward, and the gap 3 of two closure plates 2 is arc-shaped.

Referring to Figure 5, the check (non-return) valve that the third embodiment of the utility model provides includes three pieces closure plate 2, three closings Gap 3 between piece 2 is that three sections of starting points are identical, length is identical and equally distributed ray.

The check (non-return) valve that the 4th kind of embodiment of the utility model provides includes a piece of closure plate 2, closure plate 2 and 1 inner wall of tube body Cooperation, the end of closure plate 2 press closer the formation gap 3 on 1 inner wall of tube body.
