Description

Technical Field

[0001] The present invention relates to the technical field of high-temperature impact tests for automotive sealing strips, and specifically to a detection device for high-temperature impact tests of automotive sealing strips. Background Art

[0002] Automotive sealing strips are one of the important parts of an automobile, with functions of sound insulation, dust prevention, water seepage prevention, and shock absorption, maintaining and protecting the small environment inside the vehicle, thus playing an important protective role for vehicle users, electromechanical devices, and accessories. Once the sealing strip is affected by high temperature, it is prone to aging and damage, which may lead to a series of problems such as rain leakage inside the carriage and body corrosion. Therefore, it is necessary to conduct high-temperature impact tests on automotive sealing strips, and only after passing the test can they be put into use.

[0003] The patent with the patent publication number CN213422607U relates to a detection device for processing sealing strips, including a detection table, a sealing detection cavity, a sealing strip fixing plate, a sealing strip, and a wear control component. The sealing detection cavity is arranged on the detection table, and the sealing strip fixing plate is arranged in the center of the sealing detection cavity. The staff of this patent installs the sealing strip on both sides of the sealing strip fixing plate, installs the detection plate on the rack, and then controls the hydraulic rod to start through the control panel to make the detection plate and the sealing strip fit.

[0004] In the above patent, when conducting detection operations on the sealing strip, during the impact test of the detection strip, since the position where the sealing strip is placed may not be directly below the impact block, during the stamping process, due to the offset state of the sealing strip, the force on the sealing strip is uneven, which will affect the detection result and make the detection result inaccurate. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a detection device for high-temperature impact tests of automotive sealing strips, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A detection device for high-temperature impact tests of automotive sealing strips includes a workbench. A support frame is fixed on the top of the workbench, a cylinder is fixed on the top of the support frame, a connecting plate is fixed to the bottom output end of the cylinder, a stamping block is fixed to the bottom of the connecting plate. A placement plate is fixed on the top of the workbench, and a heating plate is fixed to the inner wall of the placement groove on the top of the placement plate. When it is necessary to conduct detection operations on the sealing strip, place the sealing strip on the heating plate, start the cylinder to drive the stamping block to move downward by the connecting plate, and start the heating plate to adjust the temperature of the heating plate. Then, the stamping block moves downward to extrude the sealing strip for high-temperature impact detection operations. A positioning component for positioning the sealing strip is arranged on the placement plate, and an extrusion component and a cooling component are also included;

[0007] Among them, the positioning component includes a pressing block, a triangular block, a return spring, a slider, a connecting rod, a positioning plate, an L-shaped connecting rod, a hinged rod, an L-shaped transmission block, a connecting block, a rotating rod, a protective plate, and a rotating block; the pressing block is fixed to the bottom of the connecting plate, the slider is slidably installed on the top of the placing plate, the side wall of the slider is fixed with a connecting rod, the end of the connecting rod away from the slider is fixed with a positioning plate, there are two groups of positioning plates, and the two groups of positioning plates are symmetrically arranged with the center line in the vertical direction of the placing plate as the axis of symmetry. The triangular block is slidably installed at the through hole on the top of the placing plate, the top of the triangular block is fixed with an L-shaped connecting rod, one end of the L-shaped connecting rod away from the triangular block is hinged with a hinged rod, and the end of the hinged rod away from the L-shaped connecting rod is hinged on the slider. One side of the slider away from the connecting rod is fixed with an L-shaped transmission block. When the connecting plate drives the pressing block to move downward, the pressing block can press the inclined surface of the triangular block, causing the triangular block to drive the L-shaped connecting rod to move, causing the L-shaped connecting rod to press the hinged rod, causing the hinged rod to rotate at the hinge, so that the hinged rod presses the slider to move, thereby driving the connecting rod and the positioning plate to move, enabling the two groups of positioning plates to approach each other and center-position the sealing strip in the placement groove on the top of the placing plate.

[0008] According to the above technical solution, a return spring is fixed to the side wall of the triangular block, and the side of the return spring away from the triangular block is fixed inside the placing plate. When the triangular block moves, the return spring can be compressed.

[0009] According to the above technical solution, a connecting block is fixed to the side wall of the placing plate, a rotating rod is rotatably installed on the connecting block, a protective plate is fixed to the outer wall of the rotating rod, there are two groups of protective plates, and the two groups of protective plates are symmetrically arranged with the center line in the vertical direction of the placing plate as the axis of symmetry. A torsion spring is fixed to the side wall of the connecting block, and the side of the torsion spring away from the connecting block is fixed to the side wall of the protective plate. A rotating block is fixed to the outer wall of the rotating rod. When the slider moves, it can drive the L-shaped transmission block to move, causing the L-shaped transmission block to press the rotating block, causing the rotating block to rotate, so that the rotating block can drive the rotating rod and the protective plate to rotate, enabling the two groups of protective plates to shield and protect the side wall of the placing plate.

[0010] According to the above technical solution, the extrusion assembly includes a slide bar, a slide plate, a chute, an L-shaped support plate, a sleeve, an ejector rod, a connecting spring, a push rod, a push plate, a fixed rod, a movable rod, a moving block, a limiting rod, a prompting column, a return spring, a limiting rod and an inclined block. The slide bar is fixed on the side wall of the positioning plate. The side wall of the placement plate is slidably installed with a slide plate. A chute is formed on the slide plate. The slide bar penetrates through the chute and the penetration part is in fit. The bottom of the slide plate is fixed with an L-shaped support plate. The top of the L-shaped support plate is fixed with a sleeve. The inner wall of the sleeve is slidably installed with an ejector rod. The bottom of the ejector rod is fixed with a connecting spring. The bottom of the connecting spring is fixed on the inner wall of the sleeve. When the positioning plate drives the slide bar to move, the slide bar will move in the inclined groove of the chute, so that the slide plate will move downward under the extrusion force, and thus the L-shaped support plate can move downward.

[0011] According to the above technical solution, the bottom of the ejector rod is fixed with a push rod. The bottom of the push rod is fixed with a push plate. A fixed rod penetrates through the L-shaped support plate and is slidably connected at the penetration part. The top of the L-shaped support plate is slidably installed with a moving block. An activity rod is hinged on the moving block. The end of the activity rod away from the moving block is hinged on the top of the fixed rod. A limiting rod is fixed on the side wall of the moving block. When the extrusion force received by the ejector rod is too large, the ejector rod will move downward in the sleeve. The ejector rod drives the push rod to move downward, so that the push plate can move downward, the push plate drives the fixed rod to move downward, the fixed rod pulls the activity rod, the activity rod rotates at the hinge, so that the activity rod pulls the moving block to move, and the moving block moves the limiting rod out of the limiting hole of the prompting column.

[0012] According to the above technical solution, a prompting column penetrates through the L-shaped support plate. The bottom of the prompting column is fixed with an inclined block. The top of the inclined block is fixed with a return spring. The top of the return spring is fixed on the L-shaped support plate. A limiting hole is formed on the outer wall of the prompting column. The inner wall of the limiting hole is in fit with the outer wall of the limiting rod. When the limiting rod moves out of the prompting column, due to the return spring being in a stretched state, the prompting column will move upward, so that the prompting column moves out of the L-shaped support plate and moves to the top of the placement plate.

[0013] According to the above technical solution, the cooling component includes a water tank, a water pump, a cooling water pipe, a controller, a spring switch, a transmission spring and an inclined plane block. The water tank is fixed on the top of the workbench. The water pump is fixed on the right side of the water tank. The output end of the water pump is communicated with the water tank. The side of the water pump away from the water tank is fixed with a cooling water pipe. The end of the cooling water pipe away from the water pump penetrates through the side wall of the water tank, and the cooling water pipe is communicated with the water tank and is in fit with the outer wall of the heating plate.

[0014] According to the above technical solution, a controller is fixed on the top of the workbench, a spring switch is fixed on the side wall of the controller, an inclined plane block is slidably installed on the top of the workbench, a transmission spring is fixed on the side wall of the inclined plane block, and the side of the transmission spring away from the inclined plane block is fixed on the side wall of the controller. When the prompt column moves upward, it will drive the inclined block to move upward, which will cause the inclined block to squeeze the inclined plane of the inclined plane block, so as to be able to squeeze the inclined plane block to approach the controller, and thus the inclined plane block will squeeze the spring switch on the controller, causing the water pump to open, so as to be able to suck out the cooling water in the water tank and flow in the cooling water pipe, so as to be able to cool the heating plate and the sealing strip on the heating plate, which is convenient for the staff to take.

[0015] The present invention provides an automobile sealing strip high-temperature impact test detection device. It has the following beneficial effects:

[0016] (1). For this automobile sealing strip high-temperature impact test detection device, when performing high-temperature impact operation on the sealing strip, place the sealing strip in the placement groove on the top of the placement plate, and then start the air cylinder to make the extrusion block move downward. Through the cooperation of the extrusion block and the triangular block, the triangular block can drive the L-shaped connecting rod to move, so that the L-shaped connecting rod squeezes the hinge rod to rotate at the hinge, so that the slider can drive the connecting rod to move, so that the two positioning plates approach each other, so as to be able to position the sealing strip, making the sealing strip directly below the punching block, so that when performing impact operation on the sealing strip, the sealing strip is evenly stressed. And when the slider moves, the L-shaped transmission block will squeeze the rotating block, so that the rotating block drives the rotating rod and the protection plate to rotate, so that when performing impact operation, a protective effect can be achieved.

[0017] (2). For this automobile sealing strip high-temperature impact test detection device, after the high-temperature impact is over, start the air cylinder to make the connecting plate move upward. Through the cooperation of the reset spring, the two positioning plates move away from each other, and the positioning block drives the sliding rod to move in the chute of the sliding plate, so that the sliding plate can move upward. Through the L-shaped support plate and the sleeve, the ejecting rod can push up the sealing strip adhered to the heating plate, which is convenient for taking the sealing strip. And when the temperature on the heating plate is too high, the sealing strip will adhere relatively tightly, so that the ejecting rod will move into the sleeve under the extrusion force. Through the cooperation of the push rod, the push plate, the fixed rod, the movable rod, the moving block and the limiting rod, the limiting rod can move out of the limiting hole of the prompt column, releasing the limit on the prompt column. Through the cooperation of the return spring, the prompt column moves out of the L-shaped support plate to perform a prompt operation, prompting the staff that the temperature is too high and not to take the sealing strip.

[0018] (3) The high-temperature impact test detection device for the automotive sealing strip. When the prompt column drives the inclined block to move upward, the inclined surface of the inclined block will squeeze the inclined surface of the inclined block, so that the inclined block can move closer to the controller, causing the inclined block to squeeze the spring switch, turning on the water pump, and thus sucking out the cooling water in the water tank, making the cooling water flow in the cooling water pipe. Since the cooling water pipe is attached to the outer wall of the heating plate, the cooling water pipe can cool the outer wall of the heating plate. At the same time, the sealing strip can be taken, facilitating the staff to take the material. Description of the Drawings

Detailed implementation manner

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1 - 6 , an embodiment of the present invention is: a high-temperature impact test detection device for an automotive sealing strip, including a workbench 1, a support frame 2 is fixed on the top of the workbench 1, a cylinder 3 is fixed on the top of the support frame 2, a connecting plate 5 is fixed at the bottom output end of the cylinder 3, a stamping block 6 is fixed at the bottom of the connecting plate 5, a placing plate 4 is fixed on the top of the workbench 1, a heating plate 20 is fixed on the inner wall of the placing groove at the top of the placing plate 4, an adjusting knob for regulating the temperature of the heating plate 20 is arranged on the top of the workbench 1, and a positioning component for positioning the sealing strip is arranged on the placing plate 4; wherein, the positioning component includes an extrusion block 7, a triangular block 8, a return spring 9, a slider 10, a connecting rod 11, a positioning plate 12, an L-shaped connecting rod 13, a hinged rod 14, an L-shaped transmission block 22, a connecting block 15, a rotating rod 16, a protection plate 17 and a rotating block 18; the extrusion block 7 is fixed at the bottom of the connecting plate 5, a slider 10 is slidably installed on the top of the placing plate 4, a connecting rod 11 is fixed on the side wall of the slider 10, a positioning plate 12 is fixed at the end of the connecting rod 11 away from the slider 10, there are two groups of positioning plates 12, and the two groups of positioning plates 12 are symmetrically arranged with the center line in the vertical direction of the placing plate 4 as the axis of symmetry. A triangular block 8 is slidably installed at the through hole on the top of the placing plate 4, an L-shaped connecting rod 13 is fixed at the top of the triangular block 8, a hinged rod 14 is hinged at the end of the L-shaped connecting rod 13 away from the triangular block 8, and the hinged rod 14 is hinged on the slider 10 at the end away from the L-shaped connecting rod 13. An L-shaped transmission block 22 is fixed on the side of the slider 10 away from the connecting rod 11, a return spring 9 is fixed on the side wall of the triangular block 8, and the side of the return spring 9 away from the triangular block 8 is fixed inside the placing plate 4. A connecting block 15 is fixed on the side wall of the placing plate 4, a rotating rod 16 is rotatably installed on the connecting block 15, a protection plate 17 is fixed on the outer wall of the rotating rod 16, there are two groups of protection plates 17, and the two groups of protection plates 17 are symmetrically arranged with the center line in the vertical direction of the placing plate 4 as the axis of symmetry. A torsion spring is fixed on the side wall of the connecting block 15, and the side of the torsion spring away from the connecting block 15 is fixed on the side wall of the protection plate 17. A rotating block 18 is fixed on the outer wall of the rotating rod 16.

[0030] By bringing two sets of positioning plates 12 closer to each other, the positioning plates 12 can center-position the sealing strip placed on the heating plate 20, ensuring that the sealing strip is exactly at the bottom of the stamping block 6. During the impact test on the sealing strip, the force is evenly distributed, making the stamping data results more accurate.

[0031] By providing two sets of protective plates 17, when the stamping block 6 is performing stamping operations on the sealing strip, the two sets of protective plates 17 can rotate to shield the front and back of the placement plate 4, thereby achieving a protective effect. This prevents the sealing strip from being broken due to high temperature and impact during the high-temperature impact test. The protective plates 17 can prevent the broken fragments from flying everywhere, protecting the surrounding environment and the safety of personnel.

[0032] During the operation of this embodiment: When high-temperature stamping operations need to be performed on the sealing strip, first place the sealing strip in the placement groove at the top of the placement plate 4, and then start the cylinder 3. The output end of the cylinder 3 drives the connecting plate 5 to move downward, causing the extrusion block 7 to move downward. When the extrusion block 7 moves downward and presses against the inclined surface of the triangular block 8 inside the placement plate 4, the triangular block 8 is subjected to the extrusion force, enabling the return spring 9 to be compressed. Moreover, the triangular block 8 drives the L-shaped connecting rod 13 to move, causing the L-shaped connecting rod 13 to move towards the slider 10, thereby enabling the L-shaped connecting rod 13 to press against the articulated rod 14, causing the articulated rod 14 to rotate at the articulated joint, enabling the articulated rod 14 to push the slider 10 away from the protective plate 17, driving the connecting rod 11 to move, and thus enabling the connecting rod 11 to drive the two sets of positioning plates 12 closer to each other, positioning the sealing strip in the placement groove at the top of the placement plate 4 by the two sets of positioning plates 12. And when the output end of the cylinder 3 continues to drive the connecting plate 5 to move downward, the connecting plate 5 drives the stamping block 6 to move downward, enabling the stamping block 6 to perform impact operations on the sealing strip. By starting the heating plate 20, the temperature of the heating plate 20 can be adjusted to test the impact force on the sealing strip at different temperatures. And when the slider 10 drives the connecting rod 11 to move, the slider 10 can drive the L-shaped transmission block 22 to move, causing the L-shaped transmission block 22 to press against the rotating block 18, enabling the rotating block 18 to rotate, causing the rotating block 18 to drive the rotating rod 16 to rotate, causing the rotating rod 16 to drive the protective plate 17 to rotate, shielding the front and back of the placement plate 4 by the protective plate 17. And when the protective plate 17 rotates, the torsion spring will deform.

[0033] After the impact test is completed, by controlling the cylinder 3, the output end of the cylinder 3 drives the connecting plate 5 to move upward, so that the stamping block 6 can move upward, and the connecting plate 5 drives the extrusion block 7 to move upward. When the extrusion block 7 moves upward, the extrusion block 7 will no longer extrude the triangular block 8. Since the return spring 9 is in a compressed state, the return spring 9 drives the triangular block 8 to reset, and the triangular block 8 drives the L-shaped connecting rod 13 away from the slider 10, so that the L-shaped connecting rod 13 pulls the hinge rod 14, and the hinge rod 14 drives the slider 10 to approach the protection plate 17. Through the connecting rod 11, the positioning plate 12 is reset for the next positioning operation. And when the slider 10 approaches the protection plate 17, it can drive the L-shaped transmission block 22 not to extrude the rotating block 18. Since the torsion spring is in a contracted state, the torsion spring can drive the protection plate 17 to rotate and reset, so that the protection plate 17 no longer blocks the placement plate 4, and the sealing strip can be taken.

[0034] Please refer to Figures 1 - 8, on the basis of the above embodiments, another embodiment of the present invention further includes an extrusion assembly and a cooling assembly. The extrusion assembly includes a slide bar 1901, a slide plate 1902, a chute 1903, an L-shaped support plate 1904, a sleeve 1905, an ejector rod 1906, a connecting spring 1907, a push rod 1908, a push plate 1909, a fixed rod 1910, a movable rod 1912, a moving block 1911, a limiting rod 1916, a prompting column 1913, a return spring 1915, a limiting rod 1916 and an inclined block 1914. The slide bar 1901 is fixed on the side wall of the positioning plate 12, the slide plate 1902 is slidably installed on the side wall of the placement plate 4, the chute 1903 is opened on the slide plate 1902, the slide bar 1901 penetrates through the chute 1903 and the penetration part is in fit, the bottom of the slide plate 1902 is fixed with the L-shaped support plate 1904, the top of the L-shaped support plate 1904 is fixed with the sleeve 1905, the ejector rod 1906 is slidably installed on the inner wall of the sleeve 1905, the bottom of the ejector rod 1906 is fixed with the connecting spring 1907, the bottom of the connecting spring 1907 is fixed on the inner wall of the sleeve 1905, the bottom of the ejector rod 1906 is fixed with the push rod 1908, the push rod 1908 penetrates through the bottom of the L-shaped support plate 1904 and the sleeve 1905 and the penetration part is slidably connected, the bottom of the push rod 1908 is fixed with the push plate 1909, the fixed rod 1910 penetrates through the L-shaped support plate 1904 and the penetration part is slidably connected, the moving block 1911 is slidably installed on the top of the L-shaped support plate 1904, the movable rod 1912 is hinged to one end of the moving block 1911 away from the moving block 1911, the top of the fixed rod 1910 is hinged, the limiting rod 1916 is fixed on the side wall of the moving block 1911, the prompting column 1913 penetrates through the L-shaped support plate 1904 and the penetration part is slidably connected, the inclined block 1914 is fixed at the bottom of the prompting column 1913, the return spring 1915 is fixed at the top of the inclined block 1914, the top of the return spring 1915 is fixed at the bottom of the L-shaped support plate 1904, the limiting hole is opened on the outer wall of the prompting column 1913, and the inner wall of the limiting hole is in fit with the outer wall of the limiting rod 1916.

[0035] By setting the ejector rod 1906 to move upward, the sealing strip adhered to the heating plate 20 by heating on the heating plate 20 can be jacked up, so as to facilitate the staff to take the sealing strip.

[0036] Since the return spring 1915 is in a stretched state, the inclined block 1914 and the prompting column 1913 can be driven to move upward by the return spring 1915, so that the prompting column 1913 moves out from the top of the placement plate 4, so as to play a role in prompting the staff and prevent the staff from taking the sealing strip at too high a temperature, causing harm to the staff.

[0037] The cooling component includes a water tank 211, a water pump 212, a cooling water pipe 213, a controller 214, a spring switch 215, a transmission spring 216 and an inclined plane block 217. The water tank 211 is fixed to the top of the workbench 1. The water pump 212 is fixed to the right side of the water tank 211. The output end of the water pump 212 is communicated with the water tank 211. The cooling water pipe 213 is fixed to the side of the water pump 212 away from the water tank 211. The end of the cooling water pipe 213 away from the water pump 212 penetrates the side wall of the water tank 211, and the cooling water pipe 213 is communicated with the water tank 211 and is attached to the outer wall of the heating plate 20. The controller 214 is fixed to the top of the workbench 1. The spring switch 215 is fixed to the side wall of the controller 214. The inclined plane block 217 is slidably mounted on the top of the workbench 1. The transmission spring 216 is fixed to the side wall of the inclined plane block 217. The side of the transmission spring 216 away from the inclined plane block 217 is fixed to the side wall of the controller 214. The water pump 212 is electrically connected to the controller 214, and the controller 214 is electrically connected to the spring switch 215.

[0038] Cooling water is added to the water tank 211. By flowing the cooling water in the cooling water pipe 213, it can play a role in cooling the residual temperature on the heating plate 20 after processing, preventing the residual temperature on the heating plate 20 from being too high, which may cause the temperature of the sealing strip to be too high, and it is easy for the staff to get burned when taking the sealing strip.

[0039] During the operation of this embodiment: when the two positioning plates 12 approach each other, the slide bar 1901 will move in the inclined groove of the chute 1903 of the slide plate 1902, thereby causing the slide bar 1901 to press against the inclined groove of the chute 1903. Since the slide plate 1902 is subjected to the extrusion force, the slide plate 1902 moves downward, thereby driving the L-shaped support plate 1904 to move downward, causing the sleeve 1905 and the ejector rod 1906 to move downward, and the ejector rod 1906 to move away from the top of the heating plate 20. And when the processing is completed, the positioning plate 12 will drive the slide bar 1901 to move in the chute 1903. When the slide bar 1901 moves to the inclined groove of the chute 1903, the slide bar 1901 will press the slide plate 1902 to move upward, thereby causing the slide plate 1902 to drive the L-shaped support plate 1904 to move upward, and the sleeve 1905 to drive the ejector rod 1906 to move away from the top of the heating plate 20, so that the ejector rod 1906 can lift the sealing strip adhered to the heating plate 20 by heating, facilitating the staff to take the sealing strip. And when the temperature of the heating plate 20 is too high, because the remaining temperature is too high after the processing is completed, the sealing strip will be tightly adhered to the heating plate 20. Therefore, when the ejector rod 1906 presses upward on the sealing strip, due to the too tight adhesion, the ejector rod 1906 is subjected to the extrusion force, causing the ejector rod 1906 to move downward in the sleeve 1905, compressing the connecting spring 1907. And when the push rod 1908 moves downward in the L-shaped support plate 1904, the push plate 1909 will move downward, causing the push plate 1909 to drive the fixed rod 1910 to move downward, and the fixed rod 1910 to pull the movable rod 1912, causing the movable rod 1912 to rotate at the hinge, so that the movable rod 1912 pulls the moving block 1911 closer to the sleeve 1905, and the limiting rod 1916 moves out of the limiting hole of the prompt column 1913, thus releasing the limit on the prompt column 1913. Since the return spring 1915 is in a stretched state, it can drive the inclined block 1914 to move upward, causing the return spring 1915 to drive the inclined block 1914 and the prompt column 1913 to move upward, and the prompt column 1913 to move out of the top of the placing plate 4, prompting the staff to prevent the temperature of the heating plate 20 and the sealing strip from being too high, and the staff taking the sealing strip will cause harm. And when the return spring 1915 drives the inclined block 1914 to move upward, the inclined surface of the inclined block 1914 will press against the inclined surface of the inclined surface block 217, causing the inclined surface block 217 to be subjected to the extrusion force and move toward the controller 214, compressing the transmission spring 216, so that the inclined surface block 217 presses against the spring switch 215, so that the controller 214 can control the water pump 212 to start, causing the water pump 212 to suck the cooling water in the water tank 211, and the cooling water to flow into the cooling water pipe 213, and the heating plate 20 to be cooled through the cooling water pipe 213, indirectly cooling the sealing strip, facilitating the staff to take the sealing strip.

[0040] And when the prompt column 1913 moves upward, the limit rod 1916 will abut against the outer wall of the prompt column 1913, so that the connecting spring 1907 is always in a compressed state. When it is not necessary to cool the heating plate 20, the prompt column 1913 can be pushed downward to stretch the return spring 1915. When the prompt column 1913 moves to align with the limit hole and the limit rod 1916, due to the connecting spring 1907 being in a compressed state, the ejector rod 1906 drives the push rod 1908 to move upward, the push plate 1909 drives the fixed rod 1910 to move upward, the fixed rod 1910 squeezes the movable rod 1912, and the movable rod 1912 rotates at the hinge, so as to be able to push the moving block 1911 closer to the prompt column 1913, and the limit rod 1916 extends into the limit hole opened on the outer wall of the prompt column 1913, thereby fixing the prompt column 1913 for the next prompt operation. And when the prompt column 1913 moves downward, since the inclined block 1914 does not squeeze the inclined plane block 217, and the transmission spring 216 is in a compressed state, the transmission spring 216 drives the inclined plane block 217 away from the controller 214, so that the inclined plane block 217 does not squeeze the spring switch 215, and the spring switch 215 is reset, thereby being able to close the water pump 212.

The scope of the present invention is defined by the appended claims and their equivalents.
