Preferred as one, above-mentioned damping member is damping hole 37, and the flow area of this damping hole 37 is less than 78mm
2,, this damping hole 37 is located at the side of the second end 322 of above-mentioned motion bar 32, and is connected with the gas passage 34 of crossing of motion bar 32.
Preferred as one, the opening that above-mentioned reservoir chamber 1 passes in and out for supplied gas is located at its end face, specifically, this opening of reservoir chamber 1 adopts the first connecting pipe 11 to be connected with the first opening 35 of above-mentioned constant-voltage equipment 3, the opening that above-mentioned air chamber 2 passes in and out for supplied gas is located at its top, specifically be located at the end face (certainly, also can be side) of air chamber 2, the opening of air chamber 2 specifically adopts the second connecting pipe 21 to be connected with the second opening 36 of constant-voltage equipment 3.
A kind of type pressure flushing device of the present invention, before the water inlet of its reservoir chamber 1, the motion bar 32 of constant-voltage equipment 3 axially upwardly moves to by the elastic force effect of the first spring 33 and makes its second end 322 depart from the first opening 35, makes the first opening 35 of constant-voltage equipment 3 be in connected state with its second opening 36.When its reservoir chamber 1 is intake, along with the increase of water in reservoir chamber 1, the air of reservoir chamber 1 inside is compressed gradually, and arrive constant-voltage equipment 3 through the opening of reservoir chamber 1 end face and the first connecting pipe 11, now, because the first opening 35 of constant-voltage equipment 3 and the second opening 36 are in connected state (as shown in Figure 2), thus the gas arriving constant-voltage equipment 3 will be divided into two parts, wherein a part is through the first opening 35 of constant-voltage equipment 3, second opening 36 and the second connecting pipe 21 enter air chamber 2, another part is then by the port of motion bar 32 the second end 322 and cross the top that gas passage 34 enters the first chamber 38 of constant-voltage equipment 3.Face area due to the first end 321 of motion bar 32 is greater than the face area of its second end 322, thus the gas pressure that is subject to of the first end 321 of motion bar 32 gas pressure that will be greater than its second end 322 and be subject to, and the pressure differential of both is also enough to innervate, bar 32 overcomes the elastic force effect of the first spring 33 and moves downward, until the first end 321 of motion bar 32 blocks its first opening 35, constant-voltage equipment 3 is made to be equivalent to be in closed condition, as shown in Figure 3.Now, due to constant-voltage equipment 3 being also provided with damping hole 37, thus, the interior gas of reservoir chamber 1 still slowly can be entered in air chamber 2 by this damping hole 37.When reservoir chamber 1 enters full water, constant-voltage equipment 3 is still in closed condition, and the gas pressure of damping hole 37 both sides is consistent substantially, and thus, the gas entered in air chamber 2 can not be released in reservoir chamber 1 by this damping hole 37.
When starting the draining valve in reservoir chamber 1, the water yield in reservoir chamber 1 declines, gas pressure in reservoir chamber 1 is reduced, pressure differential between the first end 321 of related motion bar 32 and the second end 322 also and then reduces, and when the pressure differential of both is less than the restoring force of the first spring 33, motion bar 32 moves upward under the restoring force effect of the first spring 33, thus open its first opening 35 gradually, this first opening 35 is connected with its second opening 36, thus make Compressed Gas in air chamber 2 successively through the second connecting pipe 21, second opening 36 of constant-voltage equipment 3, first opening 35 and the first connecting pipe 11 are released in reservoir chamber 1 gradually.Along with the continuous increase of gas in reservoir chamber 1, the pressure differential that motion bar 32 two ends are subject to also and then rises, the restoring force of this pressure differential and the first spring 33 interacts, control the state of motion bar 32 axially-movable, thus regulate the aperture size between its second end 322 and first opening 35, when making gas enter reservoir chamber 1 by the first opening 35, remain the flow of relative constancy, thus enable the Compressed Gas in air chamber 2 with the earth pressure release of relative constancy in reservoir chamber 1, and then reduction is washed away noise and improves scouring effect.Compressed Gas in air chamber 2 is released in reservoir chamber 1, makes the water in reservoir chamber 1 be subject to the pressure energy of top compression air and the effect of self gravitation potential energy and realizes constant voltage and rinse.
Because damping hole 37 is less, thus, when the Compressed Gas of air chamber 2 discharges, a small amount of gas is only had to be enter in reservoir chamber 1 by this damping hole 37, that is, the setting of this damping hole 37, provide the passage that reservoir chamber 1 is vented on the one hand, avoid the gas in reservoir chamber 1 cannot discharged to air chamber 2 under constant-voltage equipment 3 closed condition, on the other hand in the process of air chamber 2 releasing compressed gas, be not enough to again the gas that constant voltage release has the pressure energy being suitable for auxiliary flush, namely, the gas with the pressure energy being suitable for auxiliary flush carries out constant voltage release mainly through constant-voltage equipment 3.
