The specific embodiment
The utility model is now described in conjunction with the accompanying drawings and embodiments.
The deodorizing draining valve of a kind of improved pattern of double controlling as shown in Figure 1, this draining valve is arranged in water tank.This draining valve comprises a water-drainage base seat 1, a line traffic control drainage mechanism 2 and miniature immersible pump control drainage mechanism 3.Described water-drainage base seat 1 is communicated with water closet, and the hydraulic draining mechanism 3 that described line traffic control drainage mechanism 2 and a miniature immersible pump are controlled is arranged on water-drainage base seat 1 top.
As shown in Fig. 2,3-1, described line traffic control drainage mechanism 2 includes a valve body, and piston 21 slips are arranged in this valve body.The bottom of described piston 21 is provided with the water shutoff rubber 22 adaptive with water-drainage base seat 1 sealing.This piston 21 is separated into upper and lower cavity by a median septum 211.As shown in Figure 8, on described median septum 211, be provided with an above through hole 2111, the upper and lower cavity of separating to be communicated with median septum 211, the through hole on median septum 211 can arrange one or more, shape and position are unrestricted, as long as be distributed on median septum 211, all can.The sectional area size summation that is arranged on all through holes on median septum 211 is no more than 15 square millimeters.The object that through hole is set is after the through hole that is communicated with upper and lower cavity is set on median septum can effectively avoids last time automatically controlled bath and fill cycle moves, in lower chamber, to understand the existence of residual air, can more convenient accurate programme-control discharging quantity of water, make its each discharging quantity of water all can keep very high stability, discharging quantity of water uniformity is high, be not subject to the impact of extraneous factor, the restriction of sectional area summation is mainly that while controlling automatically controlled bath, the interior hydraulic pressure of lower chamber guarantees reasonably comparing in reasonable interval.
The upper cavity of being separated by median septum 211 is piston control chamber 23, the one upwards actions of line traffic control mechanism controls piston 21 that a control piston 21 resets.The lower chamber of being separated by median septum 211 is the draining sap cavity 24 that pair of pistons 21 forms water pressure.As shown in Figure 8, described draining sap cavity 24 is communicated with piston control chamber 23 by through hole 2111.On median septum 211, being provided with one or more through hole 2111 plays an important role.If generally through hole 2111 is not set on median septum 211, so last time automatically controlled bath and fill cycle moved in rear lower chamber can residual air existence, these gases will exist in lower chamber always, gas flow size more or less, this is a unfavorable factor for accurate bath, and each discharging quantity of water all can produce fluctuation.Through hole 2111 is set on median septum 211, due to law of connected vessels, in lower chamber, the existence of meeting residual air can be overflow in upper cavity by through hole 2111, guarantee that draining sap cavity 24 does not have residual air, like this can more convenient accurate programme-control discharging quantity of water, make its each discharging quantity of water all can keep very high stability, discharging quantity of water uniformity is high, is not subject to the impact of extraneous factor.
In described piston control chamber 23, be provided with a back-moving spring 25 of supporting median septum 211; when described back-moving spring 25 can be guaranteed hydraulic pressure disappearance or when extraneous motive force disappears, guarantee that piston can move down reliably; guarantee that the water rubber 22 of piston 21 bottoms can seal the outfall 4 of water-drainage base seat 1 top, completes toilet drainage procedure No. one time.
Described line traffic control mechanism is mainly by an against the force of the spring and then pulls the upwards stay cord of action of whole piston 21.This stay cord is a wire rope 26, its one end connecting line control device 5, and the other end is fixedly connected with a metal derby 261, and wire rope 26 affects metal derby 261 to move up and down and is arranged in an accommodating cavity 27, and this accommodating cavity 27 is for being formed on the hollow cavity on median septum 211.
The outer end of described median septum 211 is fixedly installed the annular sliding plate 212 being sealed and matched with valve interior wall slippage; the piston rubber 213 that this annular sliding plate 212 and one is fixed on valve interior wall coordinates; so that draining sap cavity 24 forms relatively airtight space, guarantee that piston 21 can upward sliding under the effect of hydraulic pressure.
As shown in Fig. 2,3-1,3-2, the hydraulic draining mechanism 3 that described miniature immersible pump is controlled comprises a miniature immersible pump 31 of being controlled by submersible pump control device 6, the water inlet 311 of this miniature immersible pump 31 is communicated with a water tank 28 with screen pack 281, this water tank 28 is by screen pack 281 joining water box, with the water of guaranteeing water tank 28 the insides, through filtering, prevent that miniature immersible pump 31 is because the impurity in water quality blocks and cannot normally work.The delivery port 312 communicated drainage sap cavities 24 of this miniature immersible pump 31.
As shown in Figure 2, under the utility model valve body closed condition, the water rubber 22 of piston 21 bottoms seals the outfall 4 of water-drainage base seat 1 top.As shown in Figure 4, pull wire rope 26, metal derby 261 is supported on piston 21, to drive whole piston 21 to move upward, and then opens outfall 4 baths.As shown in Fig. 3-1,3-2, start miniature immersible pump 31, the water of water tank 28 is extracted out and is entered draining sap cavity 24 from the delivery port 312 of miniature immersible pump 31 by miniature immersible pump 31, in draining sap cavity 24, form immediately hydraulic pressure, whole piston 21 upward slidings under the effect of hydraulic pressure, back-moving spring 25 is compressed simultaneously, and then opens outfall 4 baths.
As shown in Fig. 1,7, water-drainage base seat 1 of the present utility model is communicated with a bleed-off passage 7, and water-drainage base seat 1 is by foul smell exhaust plant 8 described in bleed-off passage 7 connections one.In order to prevent from washing by water, during 8 work of foul smell exhaust plant, easily water suction comes up.On this bleed-off passage 7, be provided with an anti-water suction spiral terrace part 9, described anti-water suction spiral terrace part 9 as shown in Fig. 2,5, its by a plurality of along bleed-off passage spiral inner wall upwards evenly step 91 spaced apart form.
As shown in Figure 6,7, described foul smell exhaust plant 8 is provided with deodorizing medium, its inner chamber is provided with the axial flow blower 81 of a connection bleed-off passage 7, chamber wall is provided with air outlet 82, the utility model is provided with a netted sheet material that is coated with catalyst (TIO2) in this air outlet 82, this netted sheet material can be by pottery, aluminium, and the hard materials such as metal are made.Described deodorizing medium can also be one by control circuit for ozone generator 83, to control high-pressure ozone potsherds 84.Described high-pressure ozone potsherd 84 is arranged on foul smell exhaust plant 8 inner cavity tops, and contiguous air outlet 82 arranges.
When starting axial flow blower 81, from bleed-off passage 7, extract the foul smell of the stool process generation coming up, after the ozone treatment that the ozone producing through catalyst, high-pressure ozone potsherd 84 or catalyst and high-pressure ozone potsherd 84 produce, discharge the high efficiency filter people unpleasant foul smell that process produces that goes to toilet.
Above embodiment is only explanation technological thought of the present utility model; can not limit protection domain of the present utility model with this; every technological thought according to the utility model proposes, any change of doing on technical scheme basis, within all falling into the utility model protection domain.
