[0038] With reference to Figure 4 - Figure 6 , the end of the driving disc 686 away from the rotating disc 681 is fixedly connected with the outer wall of the control block 66, and the inner wall of the heating box 5 is fixedly connected with a water pump 69. The water pump 69 can suck water through the water inlet end and discharge water through the water outlet end. This technology is prior art and can be realized by those skilled in the art, so it is not described in detail in this case. The water inlet end of the water pump 69 is fixedly connected with the outer wall of the multi-way pipe 64, and the inner wall of the control block 66 is provided with a water passage hole 611. The diameter of the water passage hole 611 is the same as the inner diameter of the water outlet pipe 62, and the number of the water passage hole 611 is one. By setting the number of the water passage hole 611, it is ensured that the inside of only one water outlet pipe 62 can be in communication with the inside of the heating box 5 each time.

[0039] With reference to Figure 4 , Figure 5 and Figure 7 , the outside of the water outlet pipe 62 and the inside of the control block 66 are provided with a temperature control assembly 7. The temperature control assembly 7 includes a temperature control pipe 71, which is fixedly connected with the outer wall of the water outlet pipe 62 and is arranged in the inside of the heating box 5. By arranging the temperature control pipe 71, it is ensured that the water in the heating box 5 does not easily affect the temperature change of the area where the temperature control pipe 71 is located. The inner wall of the temperature control pipe 71 is connected with a sliding sheet 72. The area above the sliding sheet 72 is filled with a heated gas that is easy to expand. The area below the sliding sheet 72 and the inside of a gas pressure bin 73 are filled with an inert gas. The inner wall of the water outlet pipe 62 is provided with the gas pressure bin 73. The inside of the gas pressure bin 73 is in communication with the inside of the temperature control pipe 71. The inner wall of the gas pressure bin 73 is connected with a push block 74. The inner wall of the control block 66 is provided with a moving groove 75. The moving groove 75 is slidingly connected with a stop block 76. The end of the gas pressure bin 73 close to the control block 66 is shaped to match the shape of the stop block 76. By setting the shape of the end of the gas pressure bin 73, it is ensured that the stop block 76 can enter the end of the gas pressure bin 73, thereby achieving the desired effect. The end of the push block 74 close to the stop block 76 is shaped to match the shape of the end of the water outlet pipe 62 close to the control block 66. The outer wall of the stop block 76 and the inner wall of the moving groove 75 are elastically connected by a spring 77. One end of the spring 77 is fixedly connected with the outer wall of the stop block 76, and the other end of the spring 77 is fixedly connected with the inner wall of the moving groove 75.

[0040] Working principle: in use, the water pump 69 by suction will with water hole 611 communication water outlet pipe 62 inside the water body into the heating box 5, while the water body from the water pump 69 outlet, so that the heating box 5 inside the water body increases, so that the water body under the action of pressure into the multi pipe two 65, and because the water body in the heating box 5 can contact with the outer wall of exhaust pipe 2, so in the process of contact, the exhaust pipe 2 inside the waste gas heat can be absorbed by the water body, so as to achieve the effect of waste heat recovery.

[0041] When the water temperature in one of the water storage tank 61 is enough, at this time the corresponding temperature control pipe 71 inside the slide 72 above the gas expansion, so as to push the slide 72 to move down, so that the slide 72 in the process of moving down will be in the gas inside the temperature control pipe 71 push into the gas pressure warehouse 73, so that the push block 74 completely occupies the edge of the gas pressure warehouse 73 position, so as to push the block 76 from the edge groove of the gas pressure warehouse 73.

[0042] When the block 76 from the edge groove of the gas pressure warehouse 73 is pushed out, at this time the block 76 is in the internal movement groove 75, and the motor 687 drives the rotating shaft 688 to rotate, and drives the rotating disc 681 to rotate through the rotating shaft 688, so that the rotating disc 681 rotates to drive the block 683 to enter the drive hole 684, and the drive hole 684 is pressed by the drive block 683, so that the drive disc 686 rotates, so that the control block 66 rotates.

[0043] When the control block 66 rotates to the water hole 611 is aligned with the next water outlet pipe 62, at this time the block 76 is just in the next edge groove of the gas pressure warehouse 73, so that the block 76 enters the next edge groove of the gas pressure warehouse 73 under the action of spring two 77.

[0044] When the block 76 enters the next edge groove of the gas pressure warehouse 73, because the block 76 can't move, so the control block 66 can't rotate, so when the rotating disc 681 continues to rotate, the spherical surface of the drive block 683 is stressed and enters the internal movement groove 682, so the rotating disc 681 rotates relative to the drive disc 686, so as not to cause damage to the motor 687 because the rotating shaft 688 can't rotate.

[0045] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing has been described in detail, for the skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the protection scope of the present application.
