Consult Fig. 3, Fig. 4, Fig. 5 (b), Fig. 5 (c), Fig. 6 (a), Fig. 6 (b), Fig. 7 (a), Fig. 7 (b), Fig. 8 (a), Fig. 8 (b), Fig. 9, Figure 10 (b), water intaking valve C with air suction function of the present utility model is installed on the inlet opening 17 in the water tank 15, draining valve D is installed on the draining valve opening 18 in the water tank 15, one end of filling pipe 24 is connected moisturizing hole 23, the other end stretches in the overflow pipe 25 on the draining valve D, one end of wireway 14 is enclosed within on the admission pipe 2, and the other end tightly inserts in the air entry 30 of depositing on the gas blowdown channel 29 after tightly passing air guide pore 16 on the water tank 15.
Water intaking valve with air suction function of the present utility model is to increase a getter device on the basis of existing common water intaking valve, so all also existing to water tank water intake and automatic closing function of existing common water intaking valve, this is existing known technology, no longer go to live in the household of one's in-laws on getting married in the utility model and chat, water inlet main body 19 just possesses all functions of existing common water intaking valve in the utility model.
Lower mask body is introduced the course of work with water intaking valve and water-saving closet of air suction function of the present utility model, all anhydrous in water tank and closet at first, it is all anhydrous with lower trap 28 namely to go up trap 27, when external water source flows to water intaking valve C, water tank 15 interior beginnings are intake, current flow to from water inlet 20 and add water cavity 4,8 flow to water chamber 11 from the filler again, after a period of time, water chamber 11 has filled with water gradually, when the water level in the water tank 15 rose to certain altitude, piston body 9 was owing to the effect of floating body part 10 is floated, and the volume of air-breathing tank 1 is compressed to diminish, its inner air flows to by wireway 14 from suction hole 7 and deposits gas blowdown channel 29, because upper trap 27 is all anhydrous with lower trap 28, air flowed to blow-off line 26 external worlds by upper trap 27 with lower trap 28 at that time, when water tank 15 water inlets to certain the time, floating drum 22 come-ups, water inlet main body 19 stops into water, starts draining valve D and makes water tank 15 drainings, and upper trap 27 all begins water with lower trap 28;
Consult Figure 10 (a), Figure 10 (b), restart into water in the water tank 15, piston body 9 floats again owing to the effect of floating body part 10 after a period of time, the volume of air-breathing tank 1 is compressed diminishing again, its inner air again flows to by wireway 14 from suction hole 7 and deposits gas blowdown channel 29, this moment is because upper trap 27 all has water with lower trap 28, air is blocked to stay in and deposits in the gas blowdown channel 29, along with the water level in the water tank 15 rises gradually, piston body 9 also constantly rises, the volume of air-breathing tank 1 is more and more littlely compressed, its inner increasing air is urged to depositing gas blowdown channel 29 by wireway 14 from suction hole 7, the pressure of depositing in the gas blowdown channel 29 raises, thereby make the height of water level generation difference at trap 27 and lower trap 28 two ends, the water level of namely going up the other end that the water table ratio of an end that communicates with the air of depositing 29 inside, gas blowdown channel on the trap 27 communicates with ambient atmosphere is low, the water level of the other end that the water table ratio of an end that communicates with the air of depositing 29 inside, gas blowdown channel on the lower trap 28 communicates with ambient atmosphere is low, simultaneously, the water level that the water chamber that communicates with the air of air-breathing tank 1 inside is 11 ones also can be lower than the water level of 11 ones of the water chambers that communicates with ambient atmosphere, and this three's water-head is all the same, is all height h;
Owing to deposited and also had air in the gas blowdown channel 29 at that time, be squeezed out from lower trap 28 and deposit gas blowdown channel 29 so have unnecessary air;
Consult Figure 11 (a), Figure 11 (b), behind the certain hour, floating drum 22 come-up, water inlet main body 19 stops into water, and water tank 15 water inlet ends, piston body 9 are blocked by upper limit convex edge 3 and move on can not be again, and pressure everywhere reaches equilibrium state;
Consult Fig. 7 (b), Figure 12 (a), Figure 12 (b), when opening water discharge valve D, water tank 15 interior water level fast-descendings, the buoyancy that acts on the floating body part 10 loses, because the deadweight of piston body 9 and the weight of water chamber 11 interior water, piston body 9 moves down immediately, after moving down a segment distance, lower limit protuberance 12 is withstood by lower limit body 21, thereby piston body 9 can not continue to move down, still in water chamber 11, air is from depositing gas blowdown channel 29 by wireway 14 in the bottom that makes air-breathing tank 1, suction hole 7 is attracted in the air-breathing tank 1, goes up in trap 27 and the lower trap 28 water simultaneously and also is attracted to and deposits gas blowdown channel 29 and flow;
Consult Figure 13 (a), Figure 13 (b), when cistern water-discharging will finish, along with current direction bedpan and the upper trap 27 in the water tank 15, the current Fast Filling is completely gone up trap 27, deposits gas blowdown channel 29, is reached lower trap 28, it is the full whole piece blow-off line 26 of Fast Filling, thereby go into fast siphon, dirt is taken out of bedpan and 26, blowdown processes end of blow-off line;
Again consult Figure 10 (a), Figure 10 (b), again restart into water in the water tank 15, begin to enter the circulation of next round.
The specific embodiment two
Fig. 2 (a) is consulted in contrast, Fig. 2 (b) and Figure 14 (a), Figure 14 (b), Fig. 6 (a), Fig. 6 (b) and Figure 17 (a), Figure 17 (b), Fig. 7 (a), Fig. 7 (b) and Figure 18 (a), Figure 18 (b), Fig. 8 (a), Fig. 8 (b) and Figure 19 (a), Figure 19 (b), and Figure 11 (a) and Figure 20, Figure 13 (a) and Figure 21, this specific embodiment two is with the main distinction of the specific embodiment one, in the specific embodiment one, floating body part 10 is in the inside of piston body 9, the top of floating body part 10 is equal with lower limit protuberance 12, and in this specific embodiment two, floating body part 10 is in the bottom of piston body 9, also in the bottom of lower limit protuberance 12;
Fig. 3 and Figure 15 are consulted in contrast, and the wireway 14 in this specific embodiment two only has a bit distinguishing of shape with the wireway 14 in the specific embodiment one;
Fig. 4 and Figure 16 are consulted in contrast, and the water tank 15 in this specific embodiment two only has the relative position of air guide pore 16 in water tank 15 different from water tank 15 in the specific embodiment one;
Except above-mentioned 3 of not affecting utility model essence have the minute differences, the remaining part in this specific embodiment two all with the specific embodiment one in striking resemblances, so operating principle and process are also the same, no longer repeat the way here and state.
In above-mentioned two kinds of specific embodiment; moving down of piston body 9 all is the weight that relies on its deadweight and water chamber 11 interior water; in fact also can add balancing weight 35 at piston body 9; as shown in figure 22; add balancing weight 35 as the deadweight that increases piston body 9, these changes all belong to protection domain of the present utility model.
