## Background
BACKGROUND OF THE INVENTION
This invent is about one outflow device, especially for temperature control in household water supply.
In European and American regions, central-water-supplying is quite popular and normal in every household which will control each tap in the house, the same for the hot water. Europeans and Americans like to take a shower each morning, but before hot water is ready, should first run out all cold water reserved in the hose from the system to the tap. Since it is hurry in the morning if to wait beside the shower it will waste your time but if you don't wait then after running out all cold water hot water will automatically follow which will waster water. So how to multi-task (such as making breakfast but not wasting hot water) during water warming-up is a question well deserved to be discussed.
BRIEF SUMMARY OF THE INVENTION
The invent is to solve an existing problem that how to stop flowing after cold water is being run out and provide a system to control water by temperature.
To solve the above problem, this invent is going to take the following technology:
It is a temperature control outlet device, including parts as body, faceplate communicating with the outlet end of the body, and the outlet assembly inside the body. The said outlet assembly includes a valve connected to the said body. The said valve is divided into a mainstream and a diversion vent. There is a valve rod inside the channel of the said mainstream, which will open/close the said mainstream flow through a bias spring on the bottom and a memory spring on the top. The said diversion vent is connected to the diversion assembly and then makes a diversion channel. The said diversion assembly includes a switching rod with one end connected to a offsetting spring while the other connected to a button so as to open/close the said diversion channel.
To further, there is a one-way valve behind the claimed diversion channel.
To further, the claimed button is being connected to a switch inside the body which is at one side of the faceplate.

DETAILED DESCRIPTION OF THE INVENTION
Herein we will have a further explanation towards detail carrying out mode.
The first mode of carrying out the invention.
According to FIGS. 1 & 2, it is a temperature control device, including parts as body 1, faceplate 2 communicating with the outlet end of the body 1 and the outlet assembly inside the body 1. The said valve 3 is divided into a mainstream 31 and a diversion vent 32. There is a valve rod 33 inside the mainstream channel 31, which will open/close the mainstream flow 31 through a bias spring 34 on the bottom and a memory spring 35 on the top. The said diversion vent 32 is connected to the said diversion assembly and then makes a diversion channel. The said diversion assembly consist of a fixed seat 4 and a switching rod 41 located inside the fixed seat 4. A switching rod 41 one of whose side being connected to a offsetting spring 42 while the other connected to a button 43 is to open/close the diversion channel.
There is a one-way valve 44 behind the said diversion channel which can effectively prevent cold water from mainstream channel from going into diversion channel in reverse direction through diversion outlet.
The button 43 is being connected to a switch 5 inside one side body 1 of the faceplate 2. Just push the switch 5 which can move forward the button 43 and then move the switching rod 41 and then open the diversion channel. In the end the switch will reset through the offsetting spring.
There is a bore inside the valve rod 33 and its top is being connected to the trickle hole 36 of mainstream 31. When hot water is working, the memory spring 35 will push the valve rod 33 and close the mainstream 31. Since the diversion channel is still not open yet, it will increase the mainstream pressure because of the hot water. Under this circumstance, the hot water will trickle through the hole 36 and decrease the mainstream pressure so as to effectively avoid any breakdown or safety risks because of high mainstream 31 pressure. Of course, the trickle hole 36 can also be located in the switching rod 41 inside the diversion channel.
On the bottom part of the valve 3 there is an outlet 37, which is making an acute angle with the valve 3. The outlet 37 and the valve 3 is integrated into an obliquity which makes it not only easy for water running through but also simplified working process as well as saving time and energy caused by two components instead of one compound.
There are seals 6 over on/off section on both of the valve rod 33 and switching rod 41. The seals 6 are normal ring or washer which can effectively increase seal function.
The FIG. 1 also shows its working status during cold water. The arrow indicates the cold water running through the mainstream. Under this circumstance, the memory spring 35 shrinks while the valve rod 33 is on under condition of the bias spring 34 and then open the mainstream which cold water will run through.
FIG. 3 shows a working status of outflowing hot water after running out cold water. At this time, the memory spring 35 will extend and push downward the valve 33 and close the mainstream 31 then hot water can only flow through the diversion vent 32 to the diversion channel instead of mainstream 31. Since the diversion channel is closed and blocks the hot water which can only flow through the trickle hole 36 in a trickle status so as to avoid any safety issues because of high internal pressure for mainstream 31.
The FIG. 4 shows a working status for hot water working. Push the switch 5, the button 43 will push the switch rod 41 and open the diversion channel which hot water will run through (shown as the arrow); the switching rod 41 will always keep open because of the running pressure. Then the hot water will outflow.
When water temperature decreases, the memory spring 35 inside the mainstream 31 will go back to its contraction status while the valve rod 33 will move forward and open the mainstream 31. Water pressure of the diversion channel will be decreased and the switching rod 41 will close the diversion channel under condition of the reset spring 42. At this time, water will flow through the mainstream 31 and the temperature control outlet device will go back to its working status shown as in FIG. 1.
The second mode of carrying out the invention.
According to FIGS. 5, 6, 6A & 6C, it is a temperature control device, including parts as body 510, faceplate 520 which is placed at the outlet of body 510 and some internal outlet components placed inside the body 510. A valve 530, one part of the outlet components is divided into a mainstream 531 and a diversion vent 532. There is a valve rod 533 inside the mainstream channel 531, which will open/close the mainstream flow 531 through a bias spring 534 on the bottom and a memory spring 535 on the top, i.e. the main and major channel. The diversion vent 532 is connected to some diversion components and then makes a diversion channel, i.e. a minus channel.
The claimed diversion components are located at one side of the mainstream 531 which include a fixed seat 540, a switch rod 541 which is inside the fixed seat 540. The switch rod 541 connects one side to the reset spring 542 and the other to the button 543 so as to open/close the diversion channel. There is a bulge on the switching rod 541, and at the two sides of the bulge there are seals; the bulge is intended for the switching rod 541 to close the diversion channel. The bulge can be angular or arc only if it can close the diversion channel.
At this mode, since the diversion channel is a vertical structure without any reverse direction issue so no need to set a one-way valve at the end of the diversion channel as described in the first mode.
The said button 543 is being connected to the switch 550 inside the body 510 which is at one side of the faceplate 520. Push the switch 550 which can push the button 533 so as to further move the switching rod 541 and then open the diversion channel. The switch 550 will reset through springs.
The valve rod 533 whose top can also be connected to the trickle hole from the mainstream 531 (not shown) which is the same as the first mode, so no need to repeat again.
There is an outlet 537 being set at the bottom of the mainstream 531 of the valve 530. And the outlet 537 is directed to the faceplate 520.
There are seals 560 over on/off section on both of the valve rod 533 and the switching rod 541 and the seals 560 are normal rings or washers which can effectively increase seal function.
Arrows in FIG. 6A to 6B shows separately chart of diversion closure, mainstream open and water running through mainstream; FIG. 7 shows water running through diversion channel.
Working details of the temperature outlet device at this mode is the same as the first mode, both through close/open the mainstream and the diversion channel so as to switch from cold water to hot, so no more repeating.
The third mode of carrying out the invention.
FIG. 8 is a schematic section for the third mode of carrying out the invention. As shown in FIG. 8, the claimed diversion assembly are set at one side of the mainstream and include a fixed seat 840 and a switching rod 841 inside the fixed seat 841. The diversion channel is at one side of the switching rod 841 and move horizontally through 841 so as to open and close the diversion channel. There is a reset spring 842 to reset the switching rod 841; and there is the button 843 on the other side to move the switching rod 841. The button 843 is to move the switching rod 840 through the L 844.
There is also a trickle hole 845 which is connected to the diversion channel in the switching rod 841. When the switching rod 841 moves one of its side to the valve 3, then the switching rod 841 will block the diversion channel and water will flow through the trickle hole 845 so as to decrease internal pressure of the mainstream which can effectively avoid any failure or safety issues because of too much high pressure inside the mainstream.
Other structures of the temperature outlet device are the same as the first mode except the above mentioned, herein no more repeating.
The invention of the temperature control device as mentioned above, is functioning through the valve rod inside the mainstream which will close/open the mainstream via the bias spring at the bottom and the memory spring at the top. So when cold water runs out, the hot water will go inside the mainstream then the memory spring will extend because of higher temperature and push downward the valve rod to close the mainstream; then hot water can only go into the diversion channel through the diversion vent. If needs hot water, just push the button and move the switching rod which will open the diversion channel and then hot water will outflow. The temperature control device of this invent will stop outflow when running out cold water so as to save hot water and time because people can go ahead with other tasks during this time which in a way makes it pretty practical. During usage only to set up the claimed temperature control device in a bath room where is intended for a shower then can start using.
