[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1 、 Figure 2 and Figure 5 The utility model provides an embodiment: a quick-disconnect mechanism for the forced circulation pipe of a boiling pot, comprising a connecting pipe 1, which is connected to the forced circulation pipe of the boiling pot through a flange. The number of connecting pipes 1 is set to two. Through the arrangement of the two connecting pipes 1, the two connecting pipes 1 can be respectively connected to the forced circulation pipes of two boiling pots, thereby achieving the effect of connecting different forced circulation pipes.

[0034] Reference Figure 2 、 Figure 3 and Figure 5 The interior of the connecting tube 1 is provided with a protective component 3, which includes a movable groove 31. The cross-section of the movable groove 31 is rectangular, and a square block 32 is provided inside the movable groove 31. The outer wall of the square block 32 is provided with a cylindrical protrusion. The inner wall of the connecting tube 1 on the inner side of the movable groove 31 is provided with a groove whose shape matches the shape of the outer protrusion of the square block 32. Through the setting of the groove, it is ensured that when the square block 32 is at the farthest position from the other connecting tube 1, the rotating rod 33 can be limited by the setting of the protrusion and the groove so that it cannot move. The inner wall of the square block 32 is penetrated and threadedly connected with the rotating rod 33. The height of the square block 32 in the same direction as the rotating rod 33 is shorter than the height of the movable groove 31. The square block 32 is perpendicular to the slide 36 and the direction perpendicular to the rotating rod 33, that is, Figure 2 The width in the front-to-back direction shown in the figure matches the width of the movable groove 31. The outer wall of the rotating rod 33 and the movable groove 31 is at the same horizontal position and is provided with a threaded groove 34. The threaded groove 34 corresponds to the height of a quarter circle, which is consistent with the height difference between the square block 32 and the rotating rod 33 in the same direction and the height of the movable groove 31. The outer wall of the rotating rod 33 is fixedly connected with a baffle 35. The cross-sectional shape of the baffle 35 is circular, and the outer wall of the baffle 35 is spherical. The spherical surface is set to ensure that when the baffle 35 rotates with the rotating rod 33, its outer wall will not be hindered by the inner wall of the connecting pipe 1 and cannot rotate normally. The inner wall of the connecting pipe 1 is provided with a slideway 36.

[0035] Reference Figure 2 、 Figure 4 and Figure 5The cam 372 is a rectangular parallelepiped groove having a shape of a rectangular parallelepiped. The inner wall of the cam 372 is connected to the piston of the cam 372. The cross-sectional shape of the cam 372 is a right-angled trapezoid. The inclined surface of the cam 372 is arranged on one side of the middle of the mounting groove 371 at one end of the two connecting pipes 1 that are close to each other. The inclined surface is arranged to ensure that when the cam 372 is subjected to force toward the side relative to the other connecting pipe 1, it can move toward the inside of the mounting groove 371, while the other side cannot move after being subjected to force. The inner wall of the cam 372 is elastically connected to the inner wall of the mounting groove 371 by a spring 373. One end of the spring 373 is fixedly connected to the inner wall of the cam 372, and the other end of the spring 373 is fixedly connected to the inner wall of the mounting groove 371.

[0036] Reference Figure 1 、 Figure 5 and Figure 6 , the two connecting pipes 1 are fixed by a connecting assembly 2, and the connecting assembly 2 includes an air pressure chamber 21, which is opened on the inner wall of the connecting pipe 1, and the inner wall piston of the air pressure chamber 21 is connected to an insert block 22, and the outer wall of the insert block 22 is fixedly connected to an air bag 23. The initial state of the air bag 23 is a state without gas inside. The material of the air bag 23 is rubber. The material setting of the air bag 23 ensures that the air bag 23 can expand after inflation, but it takes a large driving force to expand it. The inner wall piston of the air pressure chamber 21 is connected to a slide plate 24, and the outer wall of the slide plate 24 is fixedly connected to a water retaining bar 25. The end shape of the water retaining bar 25 matches the outer wall shape of the rotating rod 33. The inner wall of the connecting pipe 1 is provided with a groove for moving the water retaining bar 25. Through the setting of the water retaining bar 25, To ensure that water cannot flow out through the slide 36, the inner wall of the plug block 22 is provided with a connecting groove 26 connecting the air pressure chamber 21 and the air bag 23. Through the setting of the connecting groove 26, the gas inside the air pressure chamber 21 can enter the air bag 23, thereby achieving the effect of expanding the air bag 23. The outer wall of the connecting pipe 1 is slidably connected with a control block 27. The material of the control block 27 is a magnet. The material of the end of the slide plate 24 close to the control block 27 is set to be a magnet, and the magnetic poles of the end of the control block 27 and the slide plate 24 close to each other are opposite. Through the setting of the magnetic pole, it is ensured that when the control block 27 moves, it can drive the slide plate 24 to move, and there is no need to open a hole on the outside of the connecting pipe 1. The outer wall of the connecting pipe 1 is provided with a slot 28, and the shape of the slot 28 matches the shape of the plug block 22.

[0037] Working principle: During use, when the forced circulation pipe of the boiling pot needs to be disassembled, the staff first rotates the rotating rod 33, so that the part of the rotating rod 33 where the threaded groove 34 is opened rotates during the rotation process. Since the front and rear directions of the square block 32 fit with the inner wall of the movable groove 31, the square block 32 has no space to rotate, so the square block 32 moves upward at this time.

[0038] At the same time, when the rotating rod 33 rotates, the blocking piece 35 is driven by the rotating rod 33 to rotate to a position where it can completely cover the connecting pipe 1.

[0039] When the square block 32 is moved so that its protrusion is separated from the internal groove of the connecting pipe 1, the staff moves the rotating rod 33 toward the direction close to the other connecting pipe 1, so that the rotating rod 33 drives the baffle 35 to move toward the direction close to the other connecting pipe 1. Because there is hot water inside the connecting pipe 1 at this time and the water is not easily compressed, the baffle 35 and the inclined surface of the baffle 372 are subjected to force during the process of the staff moving the baffle 35.

[0040] Because the baffle 372 is subjected to force in the inclined direction, it can move toward the direction of entering the installation groove 371 after being subjected to force. The two baffles 372 that were originally in contact with each other can form a hole when they move away from each other, and the water can just pass through the baffle 35 through the hole.

[0041] When the rotating rod 33 moves to a position where it cannot move further, the water just passes through the baffle 35. Since the other end of the baffle 35 is a straight surface, it will not move toward the installation groove 371 even if it is subjected to force. Since the diameter of the slide 36 is small and no other pressure is applied during the disassembly process, even if a hole is generated after the rotating rod 33 moves, the water will remain in the state inside the connecting pipe 1 under the action of water pressure. At the same time, the appearance of the hole can accelerate the cooling of the water.

[0042] At the same time, during the movement of the rotating rod 33, the rotating rod 33 pushes the water retaining bar 25 to move, thereby causing the water retaining bar 25 to drive the slide plate 24 to move, so that the gas inside the air pressure chamber 21 increases during the movement of the slide plate 24. Since the initial state of the air bag 23 is a contracted state, the air bag 23 has its own recovery force. Therefore, when the gas moves in the direction of entering the air pressure chamber 21, the air bag 23 contracts first. When the air bag 23 contracts to the point where it can no longer contract, the air bag 23 blocks the connecting groove 26. Therefore, the plug 22 and the air bag 23 can be regarded as an airtight object as a whole. Therefore, the object can leave the slot 28 under the suction of the air pressure. Therefore, the staff can easily separate the two connecting pipes 1 at this time, so that both ends of the forced circulation pipe of the boiling pot can be disassembled when blocked, thereby avoiding harm to the staff caused by the outflow of hot water and achieving the effect of improving work efficiency.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
