The heating mechanism 5 also includes a partition plate 503. The cover plate 502 is hollow. The partition plate 503 is fixedly connected to the inner cavity of the cover plate 502. The partition plate 503 divides the inner cavity of the cover plate 502 into an upper cavity and a lower cavity. The upper cavity is slidably connected to a smoke outlet 504, and the lower cavity is slidably connected to a smoke inlet 505. The smoke outlet 504 is connected to the upper cavity. 04 and the smoke inlet 505 extend into the inner wall of the cover plate 502, and a movable plate 506 is fixedly connected between the smoke outlet 504 and the smoke inlet 505. The two sides of the cover plate 502 are symmetrically connected to the rotating blocks 507.

The heating mechanism 5 also includes a slide groove 509, which is symmetrically opened on the outer walls of both sides of the chimney 501. The slide groove 509 is for the smoke outlet 504 and the smoke inlet 505 to slide. The bottom of the inner wall of the slide groove 509 is provided with a first opening 510 and a second opening 511. The first opening 51 0 is located above the second opening 511. The first opening 510 and the second opening 511 are both connected to the inner wall of the chimney 501. A movable frame 512 is symmetrically slidably connected to the interior of the chimney 501. The two ends of the movable frame 512 extend into the inner cavities of the chimney 501 and the slide groove 509, respectively. A first spring 513 is connected between the bottom end of the movable frame 512 and the chimney 501. A baffle 514 is fixedly connected to one end of the movable frame 512 located in the inner cavity of the chimney 501. The outer wall of the baffle 514 is in close contact with the inner wall of the chimney 501. The top of the baffle 514 is fixedly connected to a connecting plate 515 via a connecting column. The inner wall of the chimney 501 is fixedly connected to a fixing plate 516.

[0029] In this embodiment, water is placed in the heating chamber 4, and coal is placed in the feed hopper 3. The coal in the feed hopper 3 enters the furnace body 1 through the feed pipe 2 for combustion. The furnace body 1 heats the water in the heating chamber 4, and the smoke generated by the coal combustion is discharged through the chimney 501.

[0030] The chimney 501 is located in the inner cavity of the heating chamber 4. When the heating chamber 4 heats the water, the heat in the heating chamber 4 is used to heat the water source, and the heat is recycled to improve the heating efficiency of the water.

[0031] When the water is heated, the cover plate 502 is pushed downward, and the cover plate 502 slides downward on the outer wall of the chimney 501. At this time, the smoke outlet 504 and the smoke inlet 505 slide downward along the inner wall of the slide groove 509 until they slide to the bottom end of the slide groove 509. The rotating block 507 is rotated, and the rotating block 507 rotates to drive the screw rod 508 to rotate. The screw rod 508 rotates to drive the movable plate 506 to move. The movable plate 506 moves to drive the smoke outlet 504 and the smoke inlet 505 to enter the first opening 510 and the second opening 511 respectively, thereby fixing the cover plate 502 on the outer wall of the chimney 501.

[0032] When the cover plate 502 does not move downward, the baffle 514 is located at one end of the first opening 510 and the second opening 511 to block the first opening 510 and the second opening 511 to prevent the smoke in the chimney 501 from leaking out through the first opening 510 and the second opening 511;

[0033] When the cover plate 502 moves downward, the smoke inlet 505 slides in the slide groove 509 and contacts the movable frame 512, pushing the movable frame 512 to move downward. The movement of the movable frame 512 drives the baffle 514 to move downward. The baffle 514 moves to separate from the first opening 510 and the second opening 511, eliminating the obstruction of the first opening 510 and the second opening 511. At the same time, the movement of the baffle 514 drives the connecting plate 515 to move. The two connecting plates 515 move and contact the fixed plate 516. The connecting plate 515 and the fixed plate 516 cut off the inner cavity of the chimney 501, so that the smoke can only enter the inner cavity of the cover plate 502 through the smoke inlet 505 and then enter the chimney 501 through the smoke outlet 504.

[0034] During this process, the cover plate 502 blocks the top of the heating chamber 4 to reduce heat loss. At the same time, the smoke passes through the cover plate 502, so that the cover plate 502 heats the inner cavity of the heating chamber 4, making it easier to reuse the heat in the heating chamber 4 to heat the water source.

[0035] Please refer to Figures 6 to 8The switch mechanism 8 includes a mounting seat 801, which is fixedly connected to the outer wall of the water outlet 6, and the internal sliding connection of the mounting seat 801 is a displacement plate 802 that runs through the inner cavity of the water outlet 6. The top of the mounting seat 801 is rotatably connected to the rotating column 803, and the bottom end of the rotating column 803 is fixedly connected to the threaded rod 804, which extends into the interior of the displacement plate 802. The internal sliding connection of the mounting seat 801 is a block 805 extending to the outer wall of the rotating column 803, and a second spring 806 is connected between the block 805 and the mounting seat 801. The bottom end of the block 805 is provided with a positioning groove 807, and the interior of the mounting seat 801 is slidably connected to a positioning block 808 below the positioning groove 807.

The interior of the mounting seat 801 is slidably connected to one side of the positioning block 808 and the top rod 810, which extends to the outside of one end of the mounting seat 801.

[0036] In this embodiment, when hot water is discharged, the water outlet pipe 7 is installed at one end of the water outlet 6. During the installation process, the water outlet pipe 7 contacts the push rod 810, squeezing the push rod 810 to drive the push rod 810 to move. The push rod 810 moves to push the positioning block 808 to move, squeezing the third spring 809. The positioning block 808 moves out of the positioning groove 807, allowing the clamping block 805 to move. The rotating column 803 is rotated to drive the threaded rod 804 to rotate. The threaded rod 804 rotates to drive the displacement plate 802 to move to open the water outlet 6. The hot water in the heating chamber 4 enters the water outlet pipe 7 through the water outlet 6.

[0037] When the water outlet pipe 7 is removed, the rotating column 803 is rotated to close the water outlet 6. At the same time, the blocking block 805 is engaged with the rotating column 803 under the elastic force of the second spring 806. When the water outlet pipe 7 is removed, the water outlet pipe 7 is separated from the top rod 810, and the positioning block 808 is engaged into the positioning groove 807 under the elastic force of the third spring 809, fixing the blocking block 805 and thus fixing the rotating column 803, so as to prevent the water outlet 6 from being opened when the water outlet pipe 7 is not installed.
