Abstract
The utility model relates to a kind of air valve, comprises valve casing, has and upper gas chamber and lower chamber, be interconnected between upper gas chamber and lower chamber by valve port in valve casing, and valve port position is provided with inflation nonreturn valve core assembly; It is characterized in that: the perisporium of described lower chamber is provided with many and axially arranges and circumferentially spaced apart air hole; The periphery of described lower chamber has been coated and fixed the meshed coating of tool, and described air hole is sheltered from by described coating.Some special air bag, such as SUP plate, there is a lot of fine rule the inside, has had this coating, and these fine rules, when air bag is rolled-up, can not enters in lower chamber through air hole, stop because fine rule snaps onto problem air valve causing Valve leakage.
Description
Technical field
The utility model relates to a kind of for needing the equipment inflated as the air valve on air mattress, inflatable dinghy.
Background technique
It is all provided with gas charging valve for the equipment of comparatively large-scale needs inflation such as air mattress, inflatable dinghy.Conventional gas charging valve, comprise housing, have the active chamber be communicated with working environment and the air-inlet cavity be in communication with the outside, be interconnected between active chamber and air-inlet cavity by valve port in housing, valve port position is provided with unidirectional gas charging valve core assembly.Existing gas charging valve is filling in exhaust process, valve port is in normally open, the filtration that gas charging valve inside does not prevent impurity from entering, and therefore this valve impurity is easily entered by valve port in the equipment of needs inflation, some special air bag in addition, such as SUP plate, there is a lot of fine rule the inside, and these fine rules are when air bag is rolled-up, can be in a mess or cut-off by what twine, fine rule probably snaps on the pad of air valve, once fine rule snaps onto on the pad of air valve, will cause Valve leakage.
Unidirectional gas charging valve core assembly in general air valve only allows air to enter active chamber from air-inlet cavity, a kind of gas charging valve as disclosed in the patent No. Chinese utility model patent " a kind of gas charging valve " that is ZL201120322164.8 (notification number is CN202203458U).The mangetic core assembly of this gas charging valve adopts the valve block be made up of flexible material, and valve port is opened in its distortion by means of only valve block, and the deformation extent of valve block is limited, and therefore smaller by the throughput of valve port, charging efficiency is low.Gas charging valve does not generally possess degassing function in addition, though some outlet valves can be exhausted, but bleeding is very inconvenient, need remain at finger or instrument the state backing down unidirectional gas charging valve core assembly during exhaust, allow unidirectional gas charging valve core assembly no longer shutoff valve port, valve port keeps often opening trend, be exhausted, if need the equipment of inflation larger, period of exhaust can be very long, such exhaust process can allow people tired, and the meeting also had arranges special venting gas appliance on the equipment needing inflation, but can increase cost.
And for example a patent No. is that the Chinese utility model patent " a kind of gas charging valve " of ZL201220406033.2 (notification number is CN202746683U) discloses a kind of gas charging valve not only having the function of inflation also to have the function of exhaust, during exhaust, inflation nonreturn valve core assembly moves down under external force and deflects to be shelved on the lower end surface of rib and makes valve port keep often opening.This valve needs two actions when being vented, and namely press down and deflect, it is also not very convenient to operate.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of can effectively prevent because the foreign material such as fine rule snap into the air valve of the leakage problem that mangetic core assembly causes for above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of air valve, comprises valve casing, has and upper gas chamber and lower chamber, be interconnected between upper gas chamber and lower chamber by valve port in valve casing, and valve port position is provided with inflation nonreturn valve core assembly; It is characterized in that: the perisporium of described lower chamber is provided with many and axially arranges and circumferentially spaced apart air hole; The periphery of described lower chamber has been coated and fixed the meshed coating of tool, and described air hole is sheltered from by described coating.
As preferably, above-mentioned coating is the nylon wire of flexible material, nylon wire have draw materials conveniently, advantage that wear resistance is good, and be flexibility, be convenient to be coated on lower chamber periphery.Certain coating also can be the fabric of other flexible material.
This coating is suppressed by the plastic hoop being fixed on lower chamber periphery the periphery being fixed on lower chamber by above-mentioned coating.Coating and lower chamber just can be fixed by means of only plastic hoop by this structure, and the simple cost of structure is low, and plastic hoop can adopt welding manner and lower chamber periphery to fix, fixed, coating difficult drop-off.
For ease of assembling upper gas chamber and lower chamber, above-mentioned valve casing comprises shell and inner casing, and inner casing is threaded in the cavity of shell, and described valve port and upper gas chamber are arranged on inner casing, and the cavity of described shell then forms described lower chamber.
