Abstract
The invention provides a pressure balance valve in the cover of a vacuum cup, the pressure balance valve including an upper valve body, a lower valve body, a valve plug and a spring. The top end and the bottom end of the spring respectively abut on the inner parts of the valve plug and the lower valve body. The upper valve body is provided with an air channel. The air channel is composed of an upper air channel, a middle air channel and a lower air channel that are communicated. The valve plug is arranged in the middle air channel and the top end of the valve plug extends to the outer side of the upper valve body. Under the action of the spring, the valve plug controls the communication of the upper air channel and the lower air channel. When the air pressure in the vacuum cup is lower than the atmospheric pressure, the cover of the vacuum cup cannot be opened easily. At this moment, only if the upper part of the valve body is lightly pressed, the valve body overcomes the pressure of the spring and moves downwards, and the upper air channel is communicated with the lower air channel so that the pressure inside and outside the vacuum cup is balanced, and thus the cover can be opened. In addition, the upper air channel has an inclined structure, which can prevent hot steam in the vacuum cup from coming out from under the finger when a person presses the valve plug with fingers. Thus, the fingers are prevented from being scalded because of the hot steam.
Description
Technical field
The present invention relates to a kind of equilibrated valve, especially a kind of equilibrated valve for thermal cup bottle cap.
Background technique
Fig. 1 is the structural drawing of existing thermal cup bottle cap.Wherein, the bottle cap 10 of thermal cup is combined with body of vacuum cup by screw thread below.While adding water or pouring, outward winding, bottle cap 10 lid 12 is above opened by spring assembly 11, thereby drinks the water in thermal cup.Yet existing thermal cup bottle cap all exists a very large defect, when hot water adds in cup, when water is hot, bowl cover is easy to open, and this is because hot water produces water vapour, has one to be greater than atmospheric pressure, and lid is just easily opened.But many times, the water of thermal cup the inside is cold, in whole cooling process, water vapour heat absorption becomes the globule, and the air content in cup reduces, and now the air pressure in cup, lower than barometric pressure, is opened bowl cover and is just not easy very much.Some present foreign brand names particularly, as THERMOS, its comparison is exquisite, favorable sealing property, the air pressure in cup during lower than barometric pressure the air in the external world be difficult for entering in cup, open bottle cap just more difficult.Based on above-mentioned situation, therefore, be badly in need of a equilibrated valve for thermal cup bottle cap of invention.
Summary of the invention
Outside the deficiency existing in the problems referred to above, while the invention provides a kind of air pressure in thermal cup lower than barometric pressure, the equilibrated valve for thermal cup bottle cap that thermal cup bottle cap is also easy to open.
For achieving the above object, the invention provides a kind of equilibrated valve for thermal cup bottle cap, comprise upper valve body, lower valve body, spool and spring, the top of described spring and bottom difference contact are in the inside of described spool and the inside of described lower valve body, on described upper valve body, be provided with gas channel, described gas channel is by the upper airway being connected, middle air flue and lower airways form, described spool is arranged in described middle air flue, its top extends to described upper valve body outside, described spool under the effect of described spring to control being communicated with of described upper airway and described lower airways.
Further, the top of described upper airway is arranged on the top surface of described upper valve body, and its bottom is the inside that downward-sloping shape extends to described middle air flue.
Further, the bottom of described lower airways is arranged in the sidewall surfaces of described upper valve body, and its top is the inside that the shape that is inclined upwardly extends to described middle air flue.
Further, in the outside of described spool, be arranged with valve seat.
Compared with prior art, the present invention has the following advantages:
It is easy to use, with low cost, workable that the present invention has advantages of.When the air pressure of thermal cup inside is during lower than barometric pressure, as long as thermal cup bottle cap is difficult for being opened, now flicking valve body top, valve body can overcome the pressure of spring toward descending, top is communicated with lower airways, makes the inside and outside pressure balance of thermal cup, and bottle cap just can normally be opened.In addition, because upper airway is tilting structure, therefore, can prevent that the hot gas in thermal cup from sending when finger presses spool below finger, to avoid finger to be scalded by hot gas.
Accompanying drawing explanation
Fig. 1 is the structural drawing of existing thermal cup bottle cap;
Fig. 2 is structural drawing of the present invention.
Primary component symbol description is as follows:
10-bottle cap 11-spring assembly 12-lid
Valve body 22-spool under 20-upper valve body 21-
23-spring 24-valve seat 25-upper airway
Air flue in the middle of 26-lower airways 27-bottle cap 28-
Embodiment
As shown in Figure 2, the invention provides a kind of equilibrated valve for thermal cup bottle cap, comprise upper valve body 20, lower valve body 21, spool 22 and spring 23, the top of this spring 23 and bottom difference contact are in the inside of spool 22 and the inside of lower valve body 21.On upper valve body 20, be provided with gas channel, gas channel consists of with lower airways 26 upper airway 25 being connected, middle air flue 28.Spool 22 is arranged in middle air flue 28, its top extends to upper valve body 20 outsides, and spool 22 to control being communicated with of upper airway and lower airways, is arranged with valve seat 24 in the outside of spool 22 under the effect of spring 23, valve seat adopts edible silica gel as raw material, edible safety and favorable sealing property.The top of upper airway 25 is arranged on the top surface of upper valve body 20, and its bottom is the inside that downward-sloping shape extends to middle air flue 28.The bottom of lower airways 26 is arranged in the sidewall surfaces of upper valve body 20, and its top is the inside that the shape that is inclined upwardly extends to middle air flue 28.Because upper airway is tilting structure, therefore, can prevent that the hot gas in thermal cup from sending when finger presses spool below finger, to avoid finger to be scalded by hot gas.
In addition, in lower valve body, be provided with the space of moving for spool.
The present invention can be arranged on the vacant position of thermal cup bottle cap or by the bottle cap 27 of the upper valve body thermal cup in the present invention formula structure that is processed as one.Upper airway at upper valve body top contacts with atmosphere, the internal communication of lower airways and thermal cup.
Working principle of the present invention is: under normal circumstances, spring withstands spool, so that upper airway and lower airways separate.When the air pressure of thermal cup inside is during lower than barometric pressure, bottle cap is difficult for opening, and as long as now flicking spool top, spool overcomes the pressure of spring toward descending, and upper airway is communicated with lower airways, the inside and outside pressure balance of thermal cup, and bottle cap just can normally be opened.
Only as described above, be only preferred embodiment of the present invention, such as professional who are familiar with this art. after understanding technological means of the present invention, natural energy, according to actual needs, is changed under instruction of the present invention.Therefore all equal variation and modifications of doing according to the present patent application the scope of the claims, once should still remain within the scope of the patent.
