Meanwhile, the diameter and length of the buffer tube 15 in the present application can be selected more than the actual delivery length of the hot water inlet channel 3 pipe.

Wherein, one side of the surface of the valve body 1 is fixedly provided with a detection box 17 positioned above the hot water inlet channel 3, one side of the top end surface of the detection box 17 is fixedly provided with a peep sight glass 18 for observing the inner cavity of the detection box 17, the inner wall of the detection box 17 is movably provided with a detection piston 19, the surface of the detection piston 19 is an inclined surface, the inner wall of the detection box 17 is provided with a movable block 20 which is in sliding connection through a rectangular convex block, the bottom surface of the movable block 20 is arranged into an inclined surface matched with the detection piston 19, the top end of the movable block 20 penetrates through the valve body 1 and is fixedly connected with a blocking block matched with an annular groove on the mixing valve core 5, one end of the movable block 20 is fixedly arranged in the inner cavity of the detection box 17 and is provided with a reset tension spring 21, one end of the reset tension spring 21 is fixedly arranged with the detection box 17, the surface of the movable block 20 is fixedly provided with a warning, therefore, the detection box 17 is installed, the detection piston 19 is installed in the detection box 17, the detection box 17 and the hot water inlet channel 3 form a sealed cavity through the detection piston 19, meanwhile, the movable block 20 is installed on the detection box 17, and the top end of the movable block 20 is matched with the annular groove on the mixing valve core 5, therefore, when hot water exists in the inlet channel 3, the air at the bottom of the detection piston 19 is heated and expanded, the detection piston 19 pushes the movable block 20, meanwhile, the blocking block at the top end of the movable block 20 extends into the inner cavity of the valve main body 1, and after the mixing valve core 5 moves upwards, the blocking block is inserted into the annular groove on the mixing valve core 5, finally, after the hot water exists in the inlet channel 3, the mixing valve core 5 cannot be pressed down again due to the influence of the blocking block, therefore, the purpose of avoiding heat storage again due to the hot water existing in the hot water pipeline is achieved, and, in order to avoid the phenomenon that the mixing valve core 5 is clamped by the blocking block after the position is restored, the top end of the blocking block is provided with a bevel angle.

Wherein, the warning block 22 is two rectangular blocks with equal area, the color of the rectangular blocks is red and blue respectively, the rectangular block on the warning block 22 close to the reset tension spring 21 is red, in order to achieve the purpose of warning the water source temperature of the user, two warning blocks 22 are arranged on the movable block 20, and the warning blocks 22 are red and blue, when hot water exists in the pipe of the water inlet channel 3, the movable block 20 moves towards the direction of the mixing valve core 5 under the push of the detection piston 19, meanwhile, the original blue color of the warning block 22 is changed into the red color by the observation of the sight glass 18, and similarly, when the movable block 20 is pulled back by the return tension spring 21, there is no cold water in the pipe in the water inlet 3, so the warning block 22 will change from red to blue, so that the user can visually observe the state of the hot water through the sight glass 18 during use, thereby being more convenient to use.

Wherein, the lateral wall top fixed mounting of mixing valve core 5 has a sealing ring 23 that is used for preventing rivers infiltration to 8 departments of ejecting spring, influences ejecting spring 8's life-span in order to prevent rivers infiltration to ejecting spring 8, therefore install sealing ring 23 on mixing valve core 5, and then can completely cut off the water source through sealing ring 23, great assurance ejecting spring 8 during operation's drying, avoided ejecting spring 8 to rust because of the medium and influenced life's phenomenon.

Wherein, buffer tube 24 that communicates with buffer tube 15 cavity is fixed to the lateral wall top of buffer tube 15, in order to avoid buffer tube 15 in the continuous increase of cold water medium, therefore install buffer tube 24 on buffer tube 15, its buffer tube 24 can be used to other sanitaryware uses, such as the toilet tank, etc. simultaneously, also can block it, finally, can choose whether to use it to other positions through actual installation and use.

The working principle is as follows: when the valve is used, the valve body 1 is fixed to a proper position of a bathroom, the water inlet channels 3 are communicated with cold water pipes and hot water pipes respectively, and meanwhile, the buffer pipe 15 with proper diameter and length is selected to be installed on the buffer block 14;

and (3) hot water heat collection state: by pressing the control handle 2 downwards, the mixing valve core 5 is enabled to compress the ejection spring 8 downwards, meanwhile, the annular groove on the mixing valve core 5 communicates the hot water inlet channel 3 with the buffer cavity 10, so that cold water in the hot water inlet channel 3 flows into the inner cavity of the buffer block 14 through the buffer cavity 10, and a medium is transmitted into the buffer tube 15 through the buffer block 14 and jacks up the buffer piston 16, and then;

hot water arrival prompting: the water continuously flows into the buffer tube 15, then when hot water flows through the water inlet channel 3, the gas in the inner cavity of the detection box 17 and at the bottom of the detection piston 19 is heated to expand, so that the detection piston 19 moves upwards, the detection piston 19 contacts the movable block 20 to drive the movable block 20 to move towards the direction of the mixing valve core 5, meanwhile, the warning block 22 looking towards the peep sight glass 18 is changed from original blue to red, therefore, the hot water can be seen to be delivered, the mixing valve core 5 can rise by loosening the control handle 2 and receiving the elastic force of the ejection spring 8, and the annular groove on the mixing valve core 5 is just clamped to the top end of the warning block 22, and meanwhile, the water retaining ring 7 on the side wall of the mixing valve core 5 blocks the water inlet of the water inlet channel 3, and then;

the hot water is used: the control handle 2 is pulled upwards, the mixing valve core 5 moves upwards through the control rod 6, so that the annular groove on the mixing valve core 5 corresponds to the rectangular permeable groove in a corresponding position, meanwhile, the interface between the buffer cavity 10 and the inner cavity of the valve main body 1 is blocked through the water retaining ring 7 (shown in figure 2 in the figure), then the mixing valve core 5 rotates through rotating the control handle 2 left and right to perform water temperature mixing adjustment, then water in the cold water inlet channel 3 enters the mixing valve core 5 to move, meanwhile, negative pressure is generated below the check ball 11 due to the flowing in the cold water inlet channel 3, the check ball 11 is driven to compress the check spring 13 downwards through the continuous flowing of cold water, and then the cold water in the buffer tube 15 flows into the mixing valve core 5 through the buffer block 14 and the buffer cavity 10 to be mixed until the buffer piston 16 falls to the bottom end, finally, when the cold water is not circulated, the check spring 13 of the cold water pushes the check ball 11 upwards;

starting heat collection when hot water exists in the hot water pipe: when hot water exists in the hot water inlet channel 3, the top end of the movable block 20 always jacks the annular groove of the mixing valve core 5, so when the control handle 2 is pressed downwards, the mixing valve core 5 cannot be pressed to the bottom under the influence of the movable block 20, finally, when the hot water in the inlet channel 3 is cooled, the detection piston 19 descends, meanwhile, the reset tension spring 21 is restored to the original position under the tension of the reset tension spring 21, the top end of the movable block 20 is separated from the annular groove on the mixing valve core 5, and the warning block 22 at the sight glass 18 is changed from red to blue.
