[0014] Beneficial effects of the present invention: 1. The present invention sets a first traction line and a lamp bead, so that the first traction line pulls the outer clamping component to limit the vehicle lamp detection part, and makes the sliding lamp frame located at the edge bottom of the vehicle lamp detection part. By starting the lamp bead, the lamp bead illuminates the edge bottom of the vehicle lamp detection part. When the vehicle lamp detection part is a vehicle lamp cover, the light emitted by the lamp bead will be refracted and reflected multiple times in the vehicle lamp detection part, and will be refracted and diffusely reflected on the irradiated surface of the bubble and the crack, forming a bright spot that is easier to observe, which is convenient for detecting bubbles and cracks in the vehicle lamp detection part, improving the efficiency of bubble and crack detection of the vehicle lamp detection part, and the quality of bubble and crack detection of the vehicle lamp detection part; when the vehicle lamp detection part is a vehicle lamp shell or a vehicle lamp as a whole, the light emitted by the lamp bead illuminates the side bottom of the vehicle lamp detection part, so that the diffuse reflection brightness of the light at the side bottom of the vehicle lamp detection part is higher than that of other parts of the vehicle lamp detection part, thereby strengthening the bottom contour feature of the vehicle lamp detection part, which is convenient for subsequent shape defect detection of the vehicle lamp detection part; 2. The present invention sets two cameras with different angles and adjustable directions, and enables the cameras to capture the shape characteristics of the headlight detection part after the lamp beads are enabled. The two cameras cooperate with each other to simultaneously collect images of the headlight detection part, thereby forming a stereoscopic visual detection, more accurately obtaining the three-dimensional size and shape information of the headlight detection part, and more efficiently detecting cracks and bubbles in the headlight; 3. The present invention sets a resin plate. When the camera rotates to the top, the camera faces the resin plate and energizes the headlight detection part as a whole to light up the headlight detection part. The light of the headlight detection part will shine on the resin plate, causing the light of the headlight detection part to be scattered at the fine bubbles in the resin plate, thereby forming a Tyndall effect. The light path of the headlight detection part is visualized and displayed in the resin plate. The camera detects the light distribution and uniformity of the light of the headlight detection part by photographing the light path in the resin plate, thereby effectively improving the detection efficiency of the light of the headlight detection part.

Implementation

[0017] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0018] Example 1 A visual inspection mechanism for vehicle lamp production, such as Figure 1-Figure 4 As shown, it includes a base 1, and the outer wall of the base 1 is fixedly connected to a first support frame 2 in a mirror-image distribution, and also includes a support slide bar 3, one of the first support frames 2 is fixedly connected to a support slide bar 3, and the support slide bar 3 is installed with a lighting clamping unit 4, and the lighting clamping unit 4 is used to clamp the vehicle lamp detection part and illuminate the bubbles, cracks and contour features of the vehicle lamp detection part; The lighting clamping unit 4 includes a lifting plate 401, the lifting plate 401 is slidably connected to the support slide rod 3, the bottom of the lifting plate 401 is in contact with the base 1, and both sides of the lifting plate 401 are in sliding contact with the first support frame 2, the center of the bottom of the lifting plate 401 is fixedly connected to a support shell 402, the support shell 402 is circumferentially distributed and rotatably connected to a first spool 406, the lifting plate 401 is circumferentially distributed with linear slide grooves, and the lifting plate 401 and the support shell 402 are connected to each other. A plum blossom rod 407 is fixedly connected to the lifting plate 401, and an outer clamping assembly 408 and an inner clamping assembly 409 are arranged on the plum blossom rod 407. A first elastic washer 412, a sliding lamp holder 413 and a second elastic washer 414 are slidably connected to the plum blossom rod 407. The outer clamping assembly 408, the inner clamping assembly 409 and the sliding lamp holder 413 all slide inside the linear slide groove of the lifting plate 401. One side of the outer clamping assembly 408 is connected to the first elastic washer 412, and one side of the first elastic washer 412 is connected to the sliding lamp holder 413. The movable lamp holder 413 is fixedly connected, and a lamp bead 415 is fixedly installed on the top of the sliding lamp holder 413. The top of the lamp bead 415 is lower than the top surface of the lifting plate 401 to prevent the lamp bead 415 from colliding with the lamp detection part, and one side of the sliding lamp holder 413 is fixedly connected to the second elastic gasket 414. A guide ring 410 is provided at the bottom of the outer clamping component 408, and a first traction line 411 is wound around the guide ring 410. One end of the first traction line 411 passes through the supporting shell 402 and is fixedly connected to the first spool 40 6. The other end of the first traction line 411 is connected to the inner clamping assembly 409, so that when the first spool 406 is pulled, the pulling direction of the inner clamping assembly 409 can be changed through the guide ring 410, so that the outer clamping assembly 408 and the inner clamping assembly 409 move close to each other. A driving assembly is installed at the bottom of the supporting shell 402. The driving assembly is connected to the first spool 406 through a damping rod. By driving the first spool 406 to rotate, the outer clamping assembly 408 adjusts the position of the lamp bead 415.

[0019] The staff first places the headlight detection part on the lifting plate 401 so that the detected surface of the headlight detection part faces upward to facilitate observation of the headlight detection part. Then the staff starts the driving assembly to rotate the first spool 406, so that the circumferential outer wall of the first spool 406 winds up the first traction line 411. The first traction line 411 is wound up so that the length of the first traction line 411 located outside the supporting shell 402 becomes shorter, thereby generating a pulling force to pull the guide ring 410. The guide ring 410 is pulled and drives the outer clamping assembly 408 to slide on the plum blossom rod 407. At the same time, the pulling force of the first traction line 411 will pull the inner clamping assembly 409 to slide on the plum blossom rod 407, so that the inner clamping assembly 409 and the outer clamping assembly 408 are close to each other, and the outer clamping component 408 will push the first elastic gasket 412 to move synchronously during the movement. When the first elastic gasket 412 moves, it will drive the sliding lamp holder 413 to move synchronously, so that the sliding lamp holder 413 drives the second elastic gasket 414 and the lamp bead 415 to move synchronously. When the outer clamping component 408 contacts the headlight detection part, the headlight detection part is clamped and limited by the outer clamping component 408. At this time, the outer clamping component 408 is limited by the headlight detection part and cannot move. The length of the first traction line 411 located outside the supporting shell 402 continues to shorten, so that the first traction line 411 pulls the inner clamping component 409 to continue to approach the outer clamping component 408. During the movement of the inner clamping component 409, the second elastic gasket 414 is squeezed. 4. When the second elastic gasket 414 is squeezed and deformed, it will drive the sliding lamp holder 413 to move and squeeze the first elastic gasket 412, so that the first elastic gasket 412 and the second elastic gasket 414 are deformed to the same extent synchronously, so that the sliding lamp holder 413 is always located in the middle of the outer clamping component 408 and the inner clamping component 409. At this time, the sliding lamp holder 413 is located at the edge bottom of the headlight detection part. The staff starts the lamp bead 415, and the lamp bead 415 illuminates the edge bottom of the headlight detection part. When the headlight detection part is a lampshade part of the headlight, the light emitted by the lamp bead 415 illuminates the side bottom of the headlight detection part, so that part of the light is refracted and reflected multiple times in the headlight detection part. The light reflected in the headlight detection part During the process, the light will be irradiated onto the cracks and bubbles of the headlight detection component, and will be refracted and diffusely reflected on the irradiated surfaces of the bubbles and cracks, so that the light is diffusely reflected by the bubbles and cracks and propagates through the headlight detection component to the outside, forming a bright spot that is easier to observe, facilitating the detection of bubbles and cracks in the headlight detection component, improving the efficiency of bubble and crack detection of the headlight detection component, and the quality of bubble and crack detection of the headlight detection component; when the headlight detection component is a headlight shell or a headlight as a whole, the light emitted by the lamp bead 415 will irradiate the side and bottom of the headlight detection component, so that the diffuse reflection brightness of the light at the side and bottom of the headlight detection component is higher than that of other parts of the headlight detection component, thereby enhancing the bottom contour feature of the headlight detection component, facilitating the subsequent shape defect detection of the headlight detection component.

[0020] like Figure 4As shown, the outer clamping assembly 408 includes a first slider 4081, which slides in the linear slide groove of the lifting plate 401. The first slider 4081 is slidably connected to the plum blossom rod 407. A guide round table 4082 is detachably fixed on the top of the first slider 4081, which is used to laterally squeeze and fix the headlight detection part. The round table surface of the guide round table 4082 faces downward, so that the guide round table 4082 can squeeze the headlight detection part downward while approaching each other and squeezing the headlight detection part laterally, so that the headlight detection part The bottom is squeezed and fit with the lifting plate 401, so as to prevent the headlight detection part from moving up and down along its own inclined surface after being squeezed. The detachable connection mode of the guide round table 4082 allows the guide round table 4082 to change the corresponding height and the slope of the round table surface according to the size of the headlight detection part. The bottom of the first slider 4081 is fixedly connected to the guide ring 410, and the first tension spring 4083 is fixedly connected between the bottom of the first slider 4081 and the lifting plate 401, and one side of the first slider 4081 is fixedly connected to the first elastic washer 412.

[0021] When the outer clamping component 408 is moving, that is, when the first traction line 411 pulls the first slider 4081 to slide on the plum blossom rod 407 through the guide ring 410, the first slider 4081 will stretch the first tension spring 4083 and drive the guide table 4082 to move synchronously, so that the guide table 4082 contacts the headlight detection part, and the headlight detection part is squeezed downward under the guidance of the inclined surface of the guide table 4082, so that the headlight detection part is tightly attached to the lifting plate 401, thereby stably fixing the headlight detection part.

[0022] like Figure 4 As shown, the inner clamping assembly 409 includes a second slider 4091, and the second slider 4091 is slidably connected to the plum blossom rod 407, and the second slider 4091 slides in the linear slide groove of the lifting plate 401. A clamping block 4092 is fixedly connected to the top of the second slider 4091, and the clamping block 4092 is semi-oblate spherical. When the bottom surface of the headlight detection part is an arc surface, the semi-oblate spherical structure of the clamping block 4092 can avoid pushing the headlight detection part to move upward when squeezing the headlight detection part, and a third tension spring 4093 is connected between one side of the second slider 4091 and the supporting shell 402.

[0023] When the inner clamping component 409 is moving, that is, the first traction line 411 pulls the second slider 4091 to slide on the plum blossom rod 407, the movement of the second slider 4091 will lengthen the third tension spring 4093, and drive the top clamping block 4092 to move synchronously, so that the top arc surface of the clamping block 4092 squeezes the headlight detection part, thereby cooperating with the inclined surface of the guide table 4082, and then clamping the headlight detection part to prevent the special-shaped headlight detection part from being squeezed by the top arc surface of the clamping block 4092, causing the headlight detection part to be squeezed and moved.

[0024] like Figure 2-Figure 3 As shown, the driving assembly includes a first motor 403, the first motor 403 is installed at the bottom of the supporting shell 402, the output shaft of the first motor 403 is fixedly connected to the first gear 404, and a plurality of second gears 405 are rotatably connected inside the supporting shell 402. The second gears 405 are frictionally engaged with the first spool 406 through the damping rod, so that the first spool 406 can idle when encountering a large torque, thereby preventing the first spool 406 from twisting and breaking.

[0025] The staff starts the first motor 403 to rotate the output shaft of the first motor 403 to rotate the first gear 404. The rotation of the first gear 404 drives the second gear 405 meshing therewith to rotate in the opposite direction. The rotation of the second gear 405 drives the first spool 406 to rotate synchronously through the damping rod, thereby executing the above-mentioned clamping process of the headlight detection part. Since the headlight detection part is often irregular in shape, the lengths to which the several first traction lines 411 can be shortened outside the supporting shell 402 are often different, so that the first spool 406 can rotate at different angles. When the first spool 406 reaches the limit of the rotation angle, the second gear 405 drives the damping rod to idle, thereby preventing the first spool 406 from twisting and breaking.

[0026] Example 2 On the basis of Example 1, Figure 1 and Figure 5-Figure 8 As shown, it also includes a horizontal adjustment unit 5, which includes an annular guide rail 501, two first support frames 2 are fixedly connected to the annular guide rail 501, the top of the annular guide rail 501 is rotatably connected to an annular frame 502, the top of the annular frame 502 is provided with a first arc-shaped slide groove, the first arc-shaped slide groove is semicircular, and two first sliding frames 503 are mirror-distributed and slidingly connected in the first arc-shaped slide groove, one side of the top of the two first sliding frames 503 are rotatably connected to a rotating frame 504, and cameras 505 are fixedly installed on the top of the two rotating frames 504, and the camera 505 has a heat source capture function, which is convenient for the camera 505 to perform high temperature resistance detection and heat dissipation detection on the vehicle light detection component, and a vertical adjustment unit 6 is installed at the bottom of the rotating frame 504, and the vertical adjustment unit 6 is used to adjust the vertical angle of the camera 505 through the rotating frame 504, so that the center of the lifting plate 401 is always within the shooting range of the camera 505.

[0027] After completing the positioning of the headlight, the staff activates the camera 505. Since the center of the lifting plate 401 is always within the shooting range of the camera 505, the headlight detection part above the lifting plate 401 is also always within the shooting range of the camera 505. The camera 505 captures the shape characteristics of the headlight detection part after the lamp bead 415 is activated. The two cameras 505 cooperate with each other and simultaneously collect images of different positions and directions of the headlight detection part, thereby forming a three-dimensional visual inspection. Compared with the existing single-camera visual inspection, it can more accurately obtain the three-dimensional size and shape information of the headlight detection part, thereby more efficiently detecting cracks, bubbles and shape defects of the headlight detection part.

[0028] like Figure 5-Figure 6 As shown, the horizontal adjustment unit 5 also includes a second motor 506, and the second motor 506 is fixedly installed on one side of the other first support frame 2, and the output end of the second motor 506 is fixedly connected to a rotating shaft 507, and the rotating shaft 507 passes through the other first support frame 2 and is rotatably connected to the other first support frame 2, and one end of the rotating shaft 507 is fixedly connected to a bevel gear 508, and a bevel gear ring 509 is fixedly connected to the circumferential outer wall of the annular frame 502, and the bevel gear 508 is meshed with the bevel gear ring 509, so that the second motor 506 can drive the annular frame 502 to rotate through the bevel gear 508 and the bevel gear ring 509, thereby making the two cameras 505 rotate synchronously.

[0029] When the staff activates the camera 505, the second motor 506 can be started. The output shaft of the second motor 506 drives the bevel gear 508 to rotate through the rotating shaft 507, so that the bevel gear 508 drives the bevel gear ring 509 meshing with it to rotate. The rotation of the bevel gear ring 509 will drive the annular frame 502 to rotate on the annular guide rail 501, so that the annular frame 502 drives the first sliding frame 503 to rotate synchronously. The rotation of the first sliding frame 503 will drive the camera 505 to rotate synchronously through the rotating frame 504, so that the camera 505 can shoot the headlight detection parts from different horizontal angles, thereby improving the detection efficiency and detection effect of the headlight detection parts.

[0030] like Figure 7-Figure 9 As shown, the horizontal adjustment unit 5 also includes a third motor 510, and the third motor 510 is fixedly installed on the top of the annular frame 502, and the output end of the third motor 510 is fixedly connected to the second spool 511, the second spool 511 is rotatably connected to the annular frame 502, and the second traction line 512 is fixedly connected to the second spool 511, the second traction line 512 passes through the annular frame 502 and one of the first sliding frames 503, and is fixedly connected to the other first sliding frame 503 along the first arc-shaped slide groove of the annular frame 502, and the second traction line 512 is externally sleeved with a cylindrical spring 513, the cylindrical spring 513 limits the range of movement of the second traction line 512, and both ends of the cylindrical spring 513 are fixedly connected to the first sliding frame 503.

[0031] When the staff activates the camera 505, the third motor 510 can be started. The output shaft of the third motor 510 rotates to drive the second spool 511 to rotate, so that the second spool 511 is wound with the second traction line 512, and the length of the second traction line 512 located in the first arc-shaped slide groove of the annular frame 502 is shortened, so that the second traction line 512 pulls one of the first sliding frames 503, so that the first sliding frame 503 slides in the first arc-shaped slide groove of the annular frame 502, and squeezes the cylindrical spring 513, so that the first sliding frame 503 drives the camera 505 to rotate synchronously through the rotating frame 504. When the third motor 510 is turned on, the second traction line 512 is turned on, and the second traction line 512 is turned on. When the output shaft of 510 rotates in the opposite direction, the output shaft of the third motor 510 rotates in the opposite direction to drive the second spool 511 to rotate synchronously, so that the second traction line 512 releases the second spool 511, and one of the first sliding frames 503 loses the pulling force of the second spool 511, so that the cylindrical spring 513 is released to push one of the first sliding frames 503 to slide in the opposite direction in the first arc-shaped slide groove of the annular frame 502, and the first sliding frame 503 drives the camera 505 to rotate synchronously through the rotating frame 504, thereby adjusting the angle between the two cameras 505, realizing multi-angle stereoscopic visual detection, and improving the detection efficiency of the vehicle light detection parts.

[0032] like Figure 1 and Figure 5-Figure 8 As shown, the vertical adjustment unit 6 includes a fourth motor 601, and the fourth motor 601 is fixedly installed in another first support frame 2. The output shaft of the fourth motor 601 passes through another first support frame 2 and is fixedly connected with a variable pitch screw 602. The circumferential outer wall of the variable pitch screw 602 has two threads with different pitches. The thread with a smaller pitch is located at the top of the variable pitch screw 602, and the thread with a larger pitch is located at the bottom of the variable pitch screw 602. The bottom of the variable pitch screw 602 is threadedly connected to the lifting plate 401, and the top of the variable pitch screw 602 is threadedly connected to the second support frame 60 3. A third support frame 604 is slidably connected to the support slide rod 3. The second support frame 603 and the third support frame 604 are fixedly connected to a rotating ring 605. An arc guide rail 606 is fixedly connected to one side of the rotating ring 605. A second arc slide groove is provided on one side of the arc guide rail 606. The angle range of the second arc slide groove corresponds to the first arc slide groove of the annular frame 502. A second sliding frame 607 is slidably connected to the second arc slide groove in a mirror-image distribution. A third arc slide groove is provided on the rotating frame 504 in a mirror-image distribution. The second sliding frame 607 slides in the third arc slide groove.

[0033] When the staff activates the camera 505, the fourth motor 601 can be started. The output shaft of the fourth motor 601 drives the variable pitch screw 602 to rotate. The rotation of the variable pitch screw 602 drives the lifting plate 401 to move upward, so that the lifting plate 401 drives the headlight detection part to move upward, and the rotation of the variable pitch screw 602 drives the second support frame 603 to move upward, so that the second support frame 603 drives the rotating ring 605 to move upward synchronously, and the upward movement of the rotating ring 605 causes the third support frame 604 to slide upward along the support slide bar 3, and drives the second sliding frame 607 to move upward through the arc guide rail 606, so that the second sliding frame 607 squeezes the third arc slide groove of the rotating frame 504, and the second sliding frame 607 drives the rotating frame 504 to rotate upward, so that the rotating frame 504 drives the camera 505 to rotate synchronously, so that the shooting range of the camera 505 always contains the headlight detection part, and the camera 505 can shoot the headlight detection part from different vertical angles, thereby improving the detection efficiency and detection accuracy of the headlight detection part.

[0034] Example 3 On the basis of Example 2, Figure 1 and Figure 5 As shown, a fourth support frame 7 is also included. The fourth support frame 7 is fixedly connected to the top of the annular frame 502. A resin plate 8 is fixedly connected inside the fourth support frame 7. The bottom of the resin plate 8 is lower than the circumferential inner wall of the fourth support frame 7, so that the camera 505 can observe the circumferential outer wall of the resin plate 8. The resin plate 8 is filled with fine bubbles, so that the light path is displayed when passing through the resin plate 8.

[0035] When the headlight detection component is an integral headlight and the camera 505 is rotated to the top, the camera 505 faces the resin plate 8, and at this time the lifting plate 401 drives the headlight detection component close to the resin plate 8. At this time, the external power supply is powered on to the headlight detection component through the wire, so that the headlight detection component is illuminated by the external power supply, and the light of the headlight detection component will be irradiated on the resin plate 8, so that the light of the headlight detection component is scattered at the fine bubbles in the resin plate 8, thereby forming a Tyndall effect, and the light path of the headlight detection component is visualized and displayed in the resin plate 8. The camera 505 detects the light distribution and uniformity of the light of the headlight detection component by shooting the light path in the resin plate 8, thereby effectively improving the detection efficiency of the light of the headlight detection component.

[0036] Example 4 On the basis of Example 2, Figure 1 and Figure 10-11As shown, a hot air cleaning unit 9 is also included. The hot air cleaning unit 9 includes a flexible support frame 901. The flexible support frame 901 is fixedly connected to the outer wall of the base 1 in a mirror-image distribution. A venturi tube 902 is fixedly connected to one end of the flexible support frame 901. A heating tube 903 is installed at one end of the venturi tube 902 for heating the airflow passing through the venturi tube 902. The other end of the venturi tube 902 is fixedly connected to an external gas cylinder with an air pressure valve through a first hose. A U-shaped tube 904 is fixedly connected to the bottom of the venturi tube 902. Water is contained in the U-shaped tube 904, and the water level is lower than the internal top surface of the U-shaped tube 904. A piston cylinder 905 is fixedly connected to one end of the U-shaped tube 904. The U-shaped tube 904 has another end. A one-way valve 906 is installed at one end, and liquid holes are opened on the piston cylinder 905 in a mirror-image distribution. A liquid guiding piston 907 is slidably connected in the piston cylinder 905. A guide groove is opened in the center of the circumferential outer wall of the liquid guiding piston 907. The guide groove is L-shaped, so that the guide groove can adjust the connection state with the liquid hole to prevent water leakage in the U-shaped tube 904. A fourth tension spring 908 is connected between the liquid guiding piston 907 and the piston cylinder 905. A three-way pressure relief valve 909 is installed on the outer wall of the U-shaped tube 904 in a connecting manner. The water inlet end of the three-way pressure relief valve 909 is connected to the water pump through a second hose, the water outlet end is connected to the inside of the U-shaped tube 904, and the pressure relief end is connected to the external water tank through a third hose.

[0037] When the staff fixes the headlight detection part on the lifting plate 401, they can start the heating tube 903 and simultaneously start the external air pressure valve to make the compressed gas in the gas cylinder flow to form an airflow. The airflow enters the venturi tube 902 through the first hose. When the airflow enters the small diameter of the venturi tube 902 from the large diameter of one end of the venturi tube 902, based on the Bernoulli principle, the airflow velocity increases and the air pressure decreases. The decrease in air pressure causes the airflow to drive the liquid guide piston 907 upward through the air pressure difference. The liquid-guiding piston 907 moves upward to stretch the fourth tension spring 908, and the guide groove of the liquid-guiding piston 907 is connected to the guide hole of the piston cylinder 905. The water in the U-shaped tube 904 flows toward the piston cylinder 905 under the guidance of the low pressure of the airflow, thereby forming a high and low liquid level difference in the U-shaped tube 904. The external gas enters the U-shaped tube 904 through the one-way valve 906. The water in the U-shaped tube 904 enters the guide hole of the piston cylinder 905 as the liquid level rises, and passes through the liquid-guiding piston 907. The high-speed airflow breaks up the water into atomized form, so that the airflow is filled with water mist. After passing through the heating tube 903, the airflow absorbs heat and heats up, and is sprayed on the headlight detection part. The water mist in the airflow cleans the surface of the headlight detection part, and the airflow performs high-temperature resistance detection on the headlight detection part. The temperature of the headlight detection part is monitored by the heat source capture function of the camera 505, so as to judge the high-temperature resistance of the headlight detection part. When the liquid level at the lower part of the U-shaped tube 904 drops to the bottom surface of the U-shaped tube 904, the air at one end of the U-shaped tube 904 can enter the other end of the U-shaped tube 904 through the bottom of the U-shaped tube 904, so that the air enters the guide hole of the piston cylinder 905 and enters the Venturi 902 through the guide groove of the liquid guide piston 907. At this time, the airflow no longer contains water mist, so that the surface of the headlight detection part will be quickly dried when the airflow is sprayed out, thereby avoiding interference with bubbles, cracks and optical path detection of the headlight detection part.

[0038] After the hot air flow is ejected, the staff closes the heating tube 903 and the external air pressure valve to stop the venturi tube 902 from working. The low pressure inside the venturi tube 902 is no longer maintained, so that the fourth tension spring 908 pulls the liquid guide piston 907 to reset, and the guide groove of the liquid guide piston 907 is disconnected from the guide hole of the piston cylinder 905. When it is necessary to add water to the U-shaped tube 904, the staff starts the external water pump to allow water to enter the three-way pressure relief valve 909 through the second hose, and the three-way pressure relief valve 909 passes the water into In the U-shaped tube 904, the circumferential outer wall of the liquid guiding piston 907 blocks the water from flowing out from the guiding hole of the piston cylinder 905, thereby increasing the water pressure in the U-shaped tube 904. When the water pressure in the U-shaped tube 904 reaches the threshold of the three-way pressure relief valve 909, one end of the three-way pressure relief valve 909 leading to the U-shaped tube 904 will be closed, so that the water flows out from the pressure relief of the three-way pressure relief valve 909 and flows into the external water tank through the third hose, thereby preventing the U-shaped tube 904 from rupturing due to excessive water added into the U-shaped tube 904.

Accordingly, the scope of the present invention should be limited only by the appended claims.
