Description
Technical field
The present invention relates to daily protective articles technical field, specially a kind of outlet valve.
Background technology
Mouth mask is a kind of amenities, refer generally to be worn over nose and mouth be used for filter into mouth and nose air, hindered with reaching
The harmful gas of gear, smell, the apparatus of spittle disengaging wearer's mouth and nose, are made with gauze or paper etc..Mouth mask is to entering lung
Air has certain filtration, and in respiratory infectious disease prevalence, in the environment of the pollutions such as dust during operation, wear masks tool
There is extraordinary effect.Mouth mask is divided into band valve port cover and without valve port cover, and general band valve port cover is relative without valve port cover, exhales
Resistance is low, wears more more comfortable.
Breather valve is the important accessory with valve port cover, and the action principle of breather valve is that the malleation of gas is discharged when exhaling by valve
Piece is blown open, rapidly to exclude internal waste gas, reduces feeling of oppression and heat when using mouth mask, and negative pressure during air-breathing can be automatically by valve
Close, to avoid the pollutant of inspiration external environment.The valve bottom of breather valve uses over-surplus fit structure with bonnet at present, causes list
It is solderable to the bottom of valve, but bonnet can not be soldered to by weldering；Or the lid of valve is soldered to, but the bottom of valve can not be soldered
Arrive, some total accessory of valve is caducous.And the interference fit of breather valve must increase cooperation position, bottom and two portions of lid
Part must increase the thickness of corresponding cooperation position, cause valve body radial direction area big, but air-flow is small by hole.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of outlet valve, valve bottom and the valve of current breather valve are solved
Lid uses over-surplus fit structure, causes the bottom of check valve solderable, but bonnet can not be soldered to by weldering；Or the lid of valve is soldered
Arrive, but the bottom of valve can not be soldered to, and some total accessory of valve is caducous；And the interference fit of breather valve is necessary
Increase coordinates position, and two parts in bottom and lid must increase the thickness of corresponding cooperation position, cause valve body radial direction area big, but air-flow
By hole it is small the problem of.
To realize object above, the present invention is achieved by the following technical programs：A kind of outlet valve, including valve bottom and valve
Lid, the valve bottom offer ventilation groove in the middle part of upper surface, and the inwall for groove of taking a breath is equidistant to be surrounded with pole, and pole is remote
Inserted link is connected between one end of ventilation groove inwall, the first fixture block is provided with the outside of the valve bottom, the upper surface at valve bottom is also opened
Provided with the first step trough, and first step trough is between two neighboring first fixture block, it is characterised in that：The bonnet
Inner side be provided with valve block, the area of the valve block is more than the area of ventilation groove, and the bottom surface of the valve block is provided with sleeve pipe, described
The internal diameter of sleeve pipe is equal with the external diameter of inserted link, the inserted link and sleeve pipe grafting, is provided with and the first fixture block on the outside of bonnet bottom surface
The second equal fixture block of quantity, first fixture block and the second fixture block clamping, formed with exhaust between two neighboring second fixture block
Mouthful, the medial surface of second fixture block offers the second step trough being adapted with the first step trough, the first step trough and second
Step trough clamping.
Further, the quantity of the pole is no less than two, compression molding between the inwall of the pole and groove of taking a breath,
Thermoplastic shaping between the pole and inserted link.
Further, using super between first step trough and the second step trough, between the first fixture block and the second fixture block
Sound wave welds or the mode of hot melt connects.
Further, the bottom surface of the bonnet is provided with decoration projection, and decorates raised top and be provided with curved-surface structure.
Further, first fixture block and the second fixture block are using not repetitional structure.
Further, the bottom surface at the valve bottom and the bottom surface of the first fixture block are provided with the second stiffener, second card
The bottom surface of block is provided with the first stiffener, and formed with reinforcement between the second stiffener on the first stiffener and the first fixture block
Ring, the shape of reinforcing ring include circular, square, triangle and rhombus.
Further, the shape of the ventilation groove includes circular, square, triangle and rhombus, the shape of the valve block and
The shape of ventilation groove is identical.
Further, the shape formed after first fixture block, the second fixture block and the assembling of valve bottom bottom surface includes circular, side
Shape, triangle and rhombus.
Further, the inner side of the bonnet 8 is provided with reinforcing prop, and being shaped as of reinforcing prop " Shu ", " one ", " T ",
" ten " one kind therein, the reinforcing prop bottom is arranged on the top of valve block, and the length of reinforcing prop is less than the length of sleeve pipe.
Further, the breather valve is integrally from the one or more in PP, ABS or nylon engineering plastic.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention
