Abstract
The utility model relates to an exhaust valve and a breathable sitting bedding provided with the exhaust valve, the exhaust valve comprises a valve seat with through holes, a valve core penetrated in the valve seat through hole and collocated with the hole in a sealing way, and a spring, one end of the spring is connected with the valve seat, the other end of the spring is connected with the valve core; the valve core can upward and downward move along the through holes of the valve seat after being pressed; the top and the bottom parts of the valve core are respectively provided with blowholes, two blowholes are communicated by the gas pipeline in the valve core; one of the blowholes is always opening at one side of the valve seat, another blowhole is sealed by the inner wall of the valve seat through hole before the valve core is pressed, another end moves to the outer of the valve seat after the valve core is pressed. Using the exhaust valve can realize breathe freely, cooling, gas exchange and so on.
Description
Technical field
The utility model relates to a kind of valve of exhausting air, and have a gas emitting valve sit the bedding pad.
Background technique
Have now and sit bedding, as cushion, mattress, sofa, because things such as linen-cotton, sponge or chemical fibre have been placed in inside, ventilative, weak heat-dissipating, the time length of seat will feel uncomfortable, in the summer of sweltering heat, even can cause dermatosis.Therefore, need a kind of effective gas escape cock, realize ventilative, heat sinking function.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of outlet valve is provided.
Another purpose of the present utility model provides a kind of ventilative bedding pad of sitting that this outlet valve is set.
The outlet valve that the utility model provides comprises the valve seat of being with through hole, be arranged in the valve seat through-hole and be the spool of seal arrangement with the hole, and an end connects the spring that valve seat, the other end connect spool; Can move along the through hole of valve seat is upper and lower behind the spool pressurized; The upper and lower part of spool is offered vent respectively, and two vents are communicated with by the breather line in the spool; One of them vent is opened on valve seat one side all the time, another vent before the spool pressurized by behind the sealing of the inwall of valve seat through-hole, the spool pressurized outside opposite side moves to valve seat.
End that is opened in spool of described two vents, a sidewall that is opened in spool.
The two ends of described spool extend to outside the valve seat, its end is provided with positive stop block respectively.
The ventilative bedding of sitting that the utility model provides comprises and sits the bedding overcoat, is provided with soft elastic pad in it; The side of sitting bedding is provided with breather cheek valve, end face is provided with described outlet valve.
Above-mentioned outlet valve is not when spool is under pressure, and vent is by the sealing of the inwall of valve seat through-hole, and behind the spool pressurized, the vent of spool and breather line are communicated with the valve seat both sides.Be provided with the bedding of sitting of this outlet valve,,, sit air in the bedding and go out by vent and form air-flow, reach effect ventilative, heat radiation because human weight moves down spool when the people sits, crouches when sitting on the bedding.At this moment, owing to formed draught head inside and outside sitting bedding, outside air sucks by breather cheek valve and sits bedding inside, realizes gas exchange.

Sectional view behind the spool pressurized of Fig. 2 outlet valve.
Fig. 3 is the ventilative sectional view of sitting bedding with outlet valve shown in Figure 1
Fig. 4 is a ventilative stereogram of sitting bedding shown in Figure 3.
Embodiment
As shown in Figure 1 and Figure 2, the outlet valve that the utility model provides comprises the valve seat 1 with central through bore, spool 2, spring 3.Spool 2 is arranged in the through hole of valve seat 1, can move along the through hole of valve seat 1 is upper and lower behind its pressurized.Contacting point at spool 2 and valve seat 1 through hole is provided with caulking gum 4, isolates to guarantee valve seat 1 upper and lower both sides sealing.The two ends of spool 2 are provided with upper and lower spacing plate washer 5,6 respectively two ends outside both sides extend to valve seat 1.One end of spring 3 is connected in the upper limit plate washer 5 that valve seat 1, the other end peak at spool.The upper and lower part of spool 2 is offered upper and lower vent 7,8, two vents respectively and is communicated with by the breather line in the spool 29.Wherein, upper vent hole 7 is opened in the upper end portion of spool 2, is positioned at valve seat 1 top one side all the time, and following vent 8 is opened in the lower sidewalls of spool 2, before spool 2 pressurizeds, because the effect of spring 3, following vent 8 be by the sealing of the inwall of valve seat through-hole, behind spool 2 pressurizeds to moving down, make down vent 8 move to valve seat 1 below one side, thus valve seat 1 upper and lower both sides are communicated with.
As shown in Figure 3, Figure 4, the ventilative bedding of sitting that the utility model provides, as cushion, mattress, sofa, it comprises sits bedding overcoat 15, sit bedding overcoat 15 and form, sit the comfortable feel that crouches to increase by rigid support 10 and the plastics or the rubber surface layer 11 that are covered on the support 10.Sit and be provided with soft elastic pad 12 in the bedding overcoat 15, as linen-cotton, sponge or chemical fibre etc.The side of sitting bedding is provided with a plurality of breather cheek valves 13, end face is provided with a plurality of above-mentioned outlet valves 14.
As mentioned above, this ventilative bedding of sitting is when idle, and spool 2 is pressurized not, because the effect of spring 3, following vent 8 is sat the inside and outside seal isolation of bedding by the sealing of the inwall of valve seat through-hole.When the people sits, crouches when sitting on the bedding, since behind human weight spool 2 pressurizeds to moving down, make down vent 8 move to valve seat 1 below one side, be communicated with inside and outside thus bedding promptly being sat in valve seat 1 upper and lower both sides, the air of sitting in the bedding forms going out of air-flow path by upper and lower vent 8 and breather line 9, reaches effect ventilative, heat radiation.At this moment, owing to formed draught head inside and outside sitting bedding, outside air sucks by breather cheek valve 13 and sits in the bedding cover, realizes gas exchange.
