Examples
Referring to fig. 1-2, a water-saving shower apparatus comprises a housing 1, a hot water pipe 2, a cold water pipe 3, and a water outlet pipe 4, wherein the hot water pipe 2 is connected with the water outlet end of an external water heater, the cold water pipe 3 is connected with an external cold water supply pipe, and the water outlet pipe 4 is directly connected with an external shower head;
the shell 1 is of a square structure, a square cavity 5 is arranged in the shell 1, the cavity 5 is respectively communicated with a hot water pipe 2, a cold water pipe 3 and a water outlet pipe 4, the hot water pipe 2 and the cold water pipe 3 respectively flow hot water and cold water out, the hot water and the cold water are mixed in the cavity 5 to form warm water, and the warm water flows out from the water outlet pipe 4 for showering;
the cold water pipe 3 and the water outlet pipe 4 are arranged oppositely, the inner wall of the cavity 5 is fixedly connected with a controller 6, the controller 6 is opposite to the pipe orifice of the hot water pipe 2, an expansion cavity 7 and a reaction cavity 8 are arranged inside the controller 6, the expansion cavity 7 is communicated with the reaction cavity 8, the sectional area of the reaction cavity 8 is far smaller than that of the expansion cavity 7, it is ensured that more thermal barrier cold contraction media exist in the expansion cavity 7, the volume change of thermal expansion is larger, the first piston 9 is conveniently driven to move, the first piston 9 is connected in the expansion cavity 7 in a sealing and sliding manner, the expansion cavity 7 is filled with the thermal expansion cold contraction media, and the shell 1 and the outer wall of the cold water pipe 3 are connected with;
a thin tube 10 is fixedly connected to one side, far away from the hot water pipe 2, of the controller 6, the thin tube 10 is communicated with the expansion cavity 7, two sliding sleeves 11 are symmetrically and fixedly arranged on the inner wall of the cavity 5, a second piston 12 is hermetically and slidably connected to the inner wall of each sliding sleeve 11, a connecting rod 13 is fixedly connected to one side, near the hot water pipe 2, of each second piston 12, a baffle 14 is fixedly connected to one end, far away from the second piston 12, of each connecting rod 13, one side, far away from the corresponding connecting rod 13, of each sliding sleeve 11 is communicated with the thin tube 10, and oil is filled in the thin tube;
the temporary storage device comprises an elastic water bag 15, the elastic water bag 15 is hermetically connected to the outer walls of the shell 1 and the cold water pipe 3, a first one-way valve 16 is arranged on the inner wall of the shell 1, and a second one-way valve 17 is arranged on the side wall of the cold water pipe 3;
the outer wall of the controller 6 is rotatably connected with an impeller 18 by a bearing, the water flow flowing out of the hot water pipe 2 contacts with the impeller 18, the impeller 18 is driven by the water flow to rotate, and the water in the cavity 5 is driven to rotate, so that the water flowing out of the hot water pipe 2 and the cold water pipe 3 is fully mixed, and the problem that the shower nozzle flowing out is overcooled or overheated water due to uneven mixing is avoided.
The sectional area of the second piston 12 is 3-5 times of that of the first piston 9, the second piston 12 is communicated with the middle of the first piston 9 through the thin tube 10, so that the two pistons always bear pressure, and the sectional area of the second piston 12 is larger than that of the first piston 9, so that the pressure borne by the second piston 12 is larger than that of a thermal barrier cold-shrinkage medium on the first piston 9, and smooth movement of the second piston 12 can be guaranteed.
In an initial state, a water outlet of the water heater is in a closed state, and the two baffles 14 are respectively abutted against the pipe orifices of the water outlet pipe 4 and the cold water pipe 3, so that cold water cannot enter the cavity 5, and liquid in the cavity 5 cannot flow out of the water outlet pipe 4. When a shower starts, a water outlet valve of the water heater is opened to enable hot water to enter the hot water pipe 2, and initially, cold water prestored in the hot water pipe 2 is driven to enter the cavity 5 firstly, and since the cold water entering the cavity 5 at the moment is all cold water, the cold water is contacted with the controller 6 and cannot enable expansion of expansion and contraction media therein to keep an original state, and the two baffles 14 do not move to enable the cold water not to flow out of the water outlet pipe 4;
because the elastic water bag 15 and the two check valves are arranged in the invention, when cold water is filled into the cavity 5 from the hot water pipe 2, the cold water enters the elastic water bag 15 through the first check valve 16 under the action of water pressure, and the water pressure in the cold water pipe 3 is also larger because the pipe orifice of the cold water pipe 3 is abutted against the baffle 14, so that the cold water in the elastic water bag 15 cannot be discharged into the cold water pipe 3 in time and is temporarily stored in the elastic water bag 15;
when the hot water in the hot-water line 2 flows out, because controller 6 is directly relative with hot-water line 2, so controller 6 can be timely feel the heat that conducts in hot-water line 2, make the expend with heat and contract with cold medium inflation in the expansion chamber 7, promote first piston 9 and remove to the one side of keeping away from hot-water line 2, and then extrude the fluid in the tubule 10 to the sliding sleeve 11 in, and then promote second piston 12 and remove to the direction of keeping away from tubule 10, until baffle 14 incompletely with two mouths of pipe offset and the gap leaks, alright flow out a small amount of cold water and hot water mixing in the cold-water line 3 this moment and become the warm water, and flow out from outlet pipe 4.
The temperature that flows out in the hot-water line 2 risees gradually, and the thermal expansion shrinkage medium expanded in the expansion chamber 7 is big more, breaks away from with two mouths of pipe completely until baffle 14, and cold water pipe 3 communicates with cavity 5 completely, and cold water in the cold water pipe 3 can be quick outflow and mix the warm water that is fit for people to bathe with hot water.
When the cold water pipe 3 is completely communicated with the cavity 5, the water pressure in the cold water pipe 3 is reduced, and at the moment, water in the elastic water bag 15 enters the cold water pipe 3 through the second one-way valve 17 under the action of the elastic pressure of the water bag body, so that the water resource is completely utilized, and the waste is avoided.
After bathing is finished, the water heater and the external cold water supply are closed, after the expansion cavity 7 is cooled, the two baffle plates 14 are restored to the initial state and are abutted against the corresponding pipe orifices, and the whole device is restored to the initial state.
Although the terms of the housing 1, the hot water pipe 2, the cold water pipe 3, the water outlet pipe 4, the cavity 5, the controller 6, the expansion chamber 7, the reaction chamber 8, the first piston 9, the thin pipe 10, the sliding sleeve 11, the second piston 12, the connecting rod 13, the baffle 14, the elastic water bag 15, the first check valve 16, the second check valve 17, the impeller 18, etc. are used more herein, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed as being without limitation to any additional limitations that may be imposed by the spirit of the present invention.
