Background technology
Present communal bathroom is in order to subtract between the toileting person cross infection chance and to guarantee air conditions between the lavatory, the water stamp pan that all generally adopts closet not contact with human body all the time; In order to save water, the discharging quantity of water in this public lavatory is all transferred few as much as possible, so regular meeting is revealed because of discharging quantity of water is few towards sordid problem, in addition, if unclean phenomenon also can appear dashing in hydraulic pressure inadequately.Therefore, public lavatory sanitary condition variation has become the cost of water saving, thereby has influence on social image and the physical and mental health of going into the lavatory public.So it is few that a kind of water supply volume is badly in need of in society, and the chamber pot flushing water new technology of dashing totally.The inventor once invented and had applied for a kind of self-priming booster that is used for the water flushed closet before this, and this self-priming booster the time can suck air in bath, and with pressing to the watering privy tool after the air of compression and the hydration, was used to improve impact force.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective of prior art, provides a kind of pan water supply volume that can make few, and the self-priming full-automatic power-assisted water economizer that dashes totally.
For achieving the above object, the self-priming full-automatic power-assisted water economizer of the utility model is that the one way valve that is used to connect running water pipe connects cleaning hose by feed pipe, cleaning hose connects pan by flushing valve again, is connected with the arm with self-priming booster between feed pipe and cleaning hose.So design, when opening flushing valve, when tap water flows to closet by feed pipe and cleaning hose, also can flow to closet by self-priming booster, when flowing through self-priming booster, your place will form negative pressure in its daraf(reciprocal of farad), and then air is drawn in the arm, the instantaneous surge of flow velocity meeting enters the chamber pot flushing water mouth rapidly, thereby greatly improves the jet douche effect after the gas-vapor mix.Because sneaking into of air arranged, partly replaced water with air, so, can also save water simultaneously.In addition, the parallel pipeline of self-priming booster arm and straight and the scheme of depositing and self-priming booster the flushing pipe scheme of parallel bypass are compared, and the former is to the better adaptability of hydraulic pressure, and service behaviour is more reliable.One way valve is when self-priming booster ejection instantaneous high pressure gas-vapor mix flows, and avoids water to reflux to the tap water direction under the pressure that increases.Therefore, it has can make the pan water supply volume few, and dashes totally, and hydraulic pressure compliance is good, the advantage of dependable performance.
As optimization, the side that one way valve connects running water pipe also is connected with ball valve, and feed pipe is by the threeway connecting branch, and arm connects cleaning hose by threeway.The then convenient maintenance of so design, the introducing of ball valve.Feed pipe is by the threeway connecting branch, and arm is then simple in structure by the connection that threeway connects cleaning hose, the convenient connection.
As optimization, feed pipe connects next section feed pipe and cleaning hose by threeway, and the feed pipe internal diameter is greater than the cleaning hose internal diameter.So design helps connecting other water-closet for bowl arranged side by side.The feed pipe internal diameter helps guaranteeing the bath flow velocity and the water yield greater than the cleaning hose internal diameter.
The preferred commercially available water saving baby board pan of the pan of institute's adapted.So design, water baby board pan more helps adapting to strong flushing.
After adopting technique scheme, the self-priming full-automatic power-assisted water economizer of the utility model has can make the pan water supply volume few, and dashes totally, hydraulic pressure compliance is good, and dependable performance is simple in structure, cost is low, and water-saving result is remarkable, the advantage that popularizing application prospect is wide.
The specific embodiment
As shown in Figure 1, the self-priming full-automatic power-assisted water economizer of the utility model is to be used to connect the ball valve 1 of running water pipe by one way valve 2 connection feed pipes 3, feed pipe 3 connects next stage feed pipe 3 and cleaning hose 4 by threeway, cleaning hose 4 connects pans 6 by flushing valve 5 again, at feed pipe 3 also successively by threeway, connect cleaning hose 4 with arm 8, the threeway of self-priming booster 7.And feed pipe 3 internal diameters are greater than cleaning hose 4 internal diameters.Its water-saving 8 raising of indices standards of national pan being washed by water are reduced to the 2-4 liter, and every inspection technology index surpasses national standard, meets the GB6952-2005 requirement fully, and promote the use of very suitable water-saving countries and regions.
