Abstract
The utility model provides an air return device of a water cup. The air return device of the water cup is installed on a cup lid of the water cup. The air return device of the water cup comprises an air return pin. The air return pin is installed on the cup lid and communicated with the interior of the water cup. An air inlet is formed at one end of the air return pin. An air return port used for ensuring that the pressure of the interior of the water cup and the atmosphere pressure are balanced is formed at the other end of the air return pin. When an infant does not suck liquid inside the water cup, the air inlet is kept closed. When the infant sucks the liquid inside the water cup, the air return port is opened. Therefore, negative pressure between the pressure of the interior of the water cup and the atmosphere pressure is formed, and suction is difficult. When the negative pressure is formed, the air return port is opened, air is rapidly returned, the pressure of the interior of the water cup and the atmosphere pressure are balanced, suction is smooth, the infant can not feel suffocated, and the large amount of liquid inside the water cup can be easily sucked for once.
Description
Technical field
The utility model relates to daily necessities, relates in particular to a kind of gas-returning devices of water tumbler.
Background technology
The general used suction pipe of water tumbler mainly is to use the atmospheric pressure principle, siphons away the part air facing to suction pipe during use, pressure diminishes in the suction pipe to cause, and for equilibrium air pressure, atmospheric pressure will force liquid rising in the suction pipe, when stopping suction, liquid in pipe descends, and pressure is just got back to balance.Yet existing water tumbler does not generally all design special gas-returning devices, causes the effort of feeling suffocated a little when sucking, and takes a few mouthfuls of it and will unclamp, and can not disposablely suck a large amount of liquid in the water tumbler.
The utility model content
The purpose of this utility model is to overcome the defective of prior art, and a kind of gas-returning devices of water tumbler is provided, and it is simple in structure, can guarantee can disposablely suck big quantity of fluid sucking the Shi Buhui effort of feeling suffocated.
The utility model is achieved in that a kind of gas-returning devices of water tumbler, be installed on the bowl cover of water tumbler, comprise return-air nail, described return-air nail is installed on the described bowl cover and the inner conducting of described water tumbler, described return-air is followed closely an end and is provided with air inlet, and the described return-air nail other end is provided with for guaranteeing the return-air mouth of water tumbler inside with the atmospheric pressure balance.
Particularly, described return-air nail comprises the first's second portion outer with exposing to described bowl cover that inserts in the described water tumbler, and described return-air mouth is located on the described second portion, and described air inlet is located in the described first.
Particularly, described return-air mouth is strip, and described air inlet is rounded.
Particularly, described bowl cover is provided with a through hole, and described return-air nail is installed on the described through hole and the inner conducting of described water tumbler.
Particularly, described return-air nails on and is provided with a groove, matches to be fixed on the described bowl cover with described through hole by described groove.
The utility model provides a kind of gas-returning devices of water tumbler, be provided with air inlet by follow closely an end at return-air, be provided with for guaranteeing the inner return-air mouth with the atmospheric pressure balance of water tumbler at the return-air nail other end, during liquid, described air inlet does not keep closing in the infant does not suck described water tumbler; In the infant sucks described water tumbler during liquid, described return-air mouth will open wide, like this, described water tumbler is inner to form negative pressure with external atmosphere pressure, at this moment sucking will difficulty, and described return-air mouth can open when negative pressure forms, and return-air makes the inner and external atmosphere pressure pressure balance of described water tumbler rapidly, sucking will very smooth and easyly not felt suffocated, and can disposablely suck big quantity of fluid in the described water tumbler like a cork.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
The gas-returning devices scheme of installation of the water tumbler that Fig. 1 provides for the utility model embodiment;
The return-air nail front view that Fig. 2 provides for the utility model embodiment;
The return-air nail vertical view that Fig. 3 provides for the utility model embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1-Fig. 3, the utility model embodiment provides a kind of gas-returning devices 1 of water tumbler, this gas-returning devices 1 also can be applied in other as in the daily necessitiess such as water tumbler, the utility model specifically illustrates with the water tumbler that a kind of infant uses always, described gas-returning devices 1 is installed on the bowl cover 2 of water tumbler, the suction pipe (not shown) of sucking for the infant also is installed on described bowl cover 2, described gas-returning devices 1 comprises return-air nail 11, described return-air nail 11 is installed on the described bowl cover 2 and the inner conducting of described water tumbler, described return-air is followed closely 11 1 ends and is provided with air inlet 111, described return-air is followed closely 11 other ends and is provided with for guaranteeing the return-air mouth 112 of described water tumbler inside with the atmospheric pressure balance, during liquid, described air inlet 111 does not keep closing in the infant does not suck described water tumbler; In the infant sucks described water tumbler during liquid, described water tumbler is inner to form negative pressure with external atmosphere pressure, at this moment sucking will be difficult, and described return-air mouth 112 can open when negative pressure forms, rapidly return-air make described water tumbler inner with the external atmosphere pressure pressure balance, sucking will very smooth and easyly not felt suffocated, and can disposablely suck big quantity of fluid in the described water tumbler like a cork.
