Description

Technical Field

[0001] The present invention relates to the technical field of crack detection, and in particular to a device and method for detecting cracks in a lip brick for photovoltaic glass. Background Art

[0002] The lip brick is located at the discharge port of the glass kiln and is a key component that guides the high-temperature molten glass to flow to the molding equipment. The performance and quality of the lip brick are directly related to the flow state and molding quality of the molten glass, which in turn affects the final quality of the photovoltaic glass.

[0003] Patent publication number CN115452854A discloses a lip brick crack detection device and method. After a coating assembly coats the outer wall of the lip brick with penetrant, a developer is sprayed onto the outer wall of the lip brick through a spray nozzle. The developer attracts the penetrant in the crack. Under a certain light source, traces of the penetrant at the crack are displayed, thereby detecting the morphology and distribution of the crack. Before the lip brick is inspected, a grinding belt a moves along the outer side of the connecting block a, and a grinding belt b moves along the outer side of the connecting block b, thereby performing a close-fitting grinding on the outer wall of the lip brick to remove impurities on the lip brick surface.

[0004] Since lip bricks go through multiple processes in the production workshop, dust in the workshop environment and brick chips generated during the processing will adhere to their surface. In addition, in the production process of lip bricks, in order to facilitate the separation of the mold and the brick, a release agent is usually used. After the lip bricks are demoulded, a small amount of release agent will remain on the surface, resulting in a thin layer of oily or powdery residue on the surface of the lip bricks.

[0005] Therefore, when the above-mentioned device is grinding the lip brick, the dust produced by grinding will enter the cracks of the lip brick under the action of the grinding belts a and b, and the dust will be compacted in the cracks, which will cause the penetrant to be unable to penetrate into the cracks of the lip brick, thereby making it impossible to accurately detect the morphology and distribution of the cracks.

[0019] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a detection method of a lip brick crack detection device for photovoltaic glass, comprising the following steps:

[0020] Firstly, the lip brick to be detected is placed on the conveying line, and then the conveying line transports the lip brick to the polishing unit region, and the double-output shaft motor drives the polishing piece to polish the lip brick;

[0021] Meanwhile, the first output shaft of the double-output shaft motor drives the rotating rod to rotate, so that the sliding shaft slides along the corrugated groove, and in the sliding process of the sliding shaft, the linear frame makes reciprocating linear motion in the sliding cylinder, so that the piston makes linear reciprocating motion in the air cylinder, at this time, the gas outside the air cylinder enters the air cylinder through the one-way valve, and then the gas in the air cylinder enters the upper cavity of the pressure tank through the one-way valve two under the action of the piston;

[0022] With the increase of the gas pressure in the upper cavity of the pressure tank, the lifting plate starts to shift towards the lower cavity under the action of the gas pressure, and after the lifting plate is shifted to the appropriate position, the compressed gas in the upper cavity enters the rotating groove through the air pipe, and then the compressed gas in the rotating groove is sprayed out through the opening at one end of the air jet pipe away from the rotating shaft;

[0023] The flow path of the compressed gas in the rotating groove into the air jet pipe is reduced, so that the flow rate of the gas after passing through the air jet pipe is accelerated, and then the high-speed airflow sprayed out of the air jet pipe will flush the surface of the lip brick during polishing.

[0024] After the lip brick is polished, the conveying line conveys the polished lip brick to the area position of the coating unit, then the liquid discharging ball contacts the curved surface to be coated of the lip brick, the lip brick presses the liquid discharging ball and the telescopic rod slides along the limiting rod, then the liquid discharging ball no longer blocks the water outlet hole, and the permeate in the storage box can be discharged through the water outlet hole;

[0025] When the lip brick is displaced, the liquid discharging ball rotates under the action of the lip brick, the rotation of the liquid discharging ball guides the permeate in the storage box to be discharged through the water outlet hole, so that the permeate is coated on the curved surface to be detected of the lip brick;

[0026] The lip brick coated with the permeate needs to be placed for a period of time, so that the permeate can fully penetrate into the pores or cracks of the lip brick, then the excess permeate on the curved surface to be detected is manually wiped off with a cleaning cloth, the developing agent is manually sprayed towards the lip brick to be detected, finally the lip brick to be detected is placed in a proper environment, the area to be detected of the lip brick is irradiated by the ultraviolet lamp, so that the cracks of the area to be detected of the lip brick are observed;

[0027] When the double-output-shaft motor operates, the second output shaft on the double-output-shaft motor drives the fan to rotate, the rotation of the fan guides the surrounding gas to flow towards the collecting cylinder, then the gas in the area of the dust collecting cover is subjected to the traction force when the fan rotates, then the flying dust particles follow the fluid into the gas collecting box from the dust collecting cover, and finally into the collecting cylinder from the gas collecting box;

[0028] When the fan rotates, the centrifugal pipe and the drainage plate outside the centrifugal pipe also rotate synchronously, the dust particles in the fluid contact the surface of the drainage plate and the inner wall of the filter cylinder, and at this time, the water in the centrifugal cavity enters the drainage cavity under the action of centrifugal force, the water in the drainage cavity is discharged from the liquid discharge hole under the action of centrifugal force, at this time, the surface of the drainage plate is attached with a layer of water film, and the dust particles in the fluid are adsorbed by the water when the fluid passes through the collecting cylinder;

[0029] After the dust particles and the water body are mixed, sewage is generated, the sewage flows to the bottom of the collecting cylinder, and then flows onto the guide plate, and then enters the filter cylinder through the guide plate, the sewage entering the filter cylinder first passes through the filter plate, and the dust particles or particulate matters in the sewage are intercepted by the filter plate, and the water body mixes with the water body at the bottom of the filter cylinder after passing through the filter plate;

[0030] When the water in the water tank is gradually discharged from the liquid discharge hole, the pressure in the water tank decreases, so that the water in the filter cylinder enters the water tank through the backflow pipe under the action of negative pressure.

[0031] Compared with the prior art, the beneficial effects of the present application are:

[0032] 1. The lip brick is polished by setting the polishing unit, the jet pipes are arranged outside the rotating shaft, the rotating rod is driven to rotate by the double-output shaft motor, then the piston delivers the gas in the gas cylinder to the pressure tank, under the action of the pressure tank and the jet pipe, the high-speed gas flushes the polished lip brick surface, thereby avoiding dust from being blocked in the cracks, improving the permeation effect of the permeating liquid, and thereby improving the detection precision of the morphology and distribution of the lip brick surface cracks;

[0033] 2. The dust flying caused by the flushing of the jet pipe will eventually settle on the lip brick surface, affecting the permeation effect of the permeating liquid, the gas collecting tank and the dust hood are set, and the fan is arranged in the gas collecting tank, so as to guide the dust into the gas collecting tank, thereby avoiding the dust flying and adhering to the lip brick surface, ensuring the permeation effect of the permeating liquid, and thereby improving the detection precision of the cracks;

[0034] 3. The collecting cylinder is set, and the drainage plate is arranged in the collecting cylinder, the water body is discharged from the drainage plate by centrifugal force, so that the water body captures the dust, avoids the dust flying, and improves the detection environment of the lip brick;

[0035] 4. The backflow pipe, the filter cylinder and the filter plate in the filter cylinder are set, so that the water body mixed with dust is collected and filtered, then reenters the water tank through the backflow pipe and continues to be used, improving the utilization rate of the water body.

[0057] The frame body 11 is provided with a double-output shaft motor 13, which includes a first output shaft and a second output shaft.

[0058] The pneumatic unit 5 further comprises a sliding cylinder 52, which is provided with a rotating rod 53, and the outer side of the rotating rod 53 is provided with a corrugated groove 531. The sliding cylinder 52 is further provided with a linear frame 54, which is clamped and slidingly arranged in the sliding cylinder 52. The linear frame 54 is symmetrically provided with a sliding shaft 55, which is slidingly arranged in the corrugated groove 531.

[0059] One end of the sliding cylinder 52 is provided with a gas cylinder 56, which is slidingly provided with a piston 561. One end of the piston 561 is provided with a connecting rod, and the other end of the connecting rod is connected with the linear frame 54. The other end of the gas cylinder 56 away from the sliding cylinder 52 is provided with a one-way valve one. The gas outside the gas cylinder 56 can enter the inside of the gas cylinder 56 through the one-way valve one. The gas cylinder 56 is arranged at the other end of the sliding cylinder 52 away from the double-output shaft motor 13. The other end of the gas cylinder 56 away from the sliding cylinder 52 is connected with the pressure tank 51. The connection between the gas cylinder 56 and the pressure tank 51 is provided with a one-way valve two, so that the gas can only enter the pressure tank 51 from the gas cylinder 56 through the one-way valve two.

[0060] The pressure tank 51 is slidingly provided with a lifting plate 57, which divides the inside of the pressure tank 51 into an upper cavity and a lower cavity. The gas cylinder 56 communicates with the upper cavity of the pressure tank 51. The lower cavity of the pressure tank 51 communicates with the rotating groove 24. The lower end of the lifting plate 57 is provided with a spring one, which is arranged in the lower cavity. When the lifting plate 57 is displaced to the appropriate position, the upper cavity of the pressure tank 51 will be in communication with the rotating groove 24.

[0061] The coating unit 12 comprises a fixed plate 14, the lower end of which is provided with a storage box 15. The upper end of the fixed plate 14 is provided with a storage tank 16, which communicates with the inside of the storage box 15. The storage box 15 and the lip brick to be coated with the curved surface profile are mutually adapted. The side of the storage box 15 away from the fixed plate 14 is arrayed with a liquid discharge ball 17. The fixed plate 14 is connected with the conveying line 1. The storage tank 16 and the storage box 15 are both filled with permeate. The permeate in the storage tank 16 can enter the storage box 15 under the action of gravity.

[0062] The water outlet hole is arranged on the storage box 15 in an array, and the water outlet hole is communicated with the internal chamber in the storage box 15. Limiting rods are symmetrically arranged at the opening edge of the water outlet hole. The limiting rods are arranged inside the storage box 15. A telescopic rod is linearly and slidably arranged on the limiting rod. Spring No. 2 is sleeved outside the telescopic rod. The liquid discharge ball 17 is rotatably arranged on the telescopic rod. The liquid discharge ball 17 is arranged at one end of the telescopic rod facing the water outlet hole. Initially, under the action of the reset elastic force of spring No. 2, the liquid discharge ball 17 blocks the water outlet hole.

[0063] In use, first, the double-output shaft motor 13 and the conveying line 1 are started, and then the lip brick to be detected is placed on the conveying line 1, and then the lip brick is transported by the assembly line. The rotating rollers on both sides of the lip brick limit the lip brick during transportation. When the lip brick is transported to the polishing unit 2, the polishing piece 23 is in contact with the curved surface to be polished of the lip brick under the elastic force of the elastic sheet at this time, and the polishing piece 23 applies appropriate pressure to the lip brick at this time.

[0064] At the same time, the first output shaft of the double-output shaft motor 13 rotates and drives the synchronous wheel one 131 to synchronously rotate. Under the action of the synchronous belt, the rotation of the synchronous wheel one 131 drives the synchronous wheel two 132 to rotate, so that the synchronous wheel two 132 drives the rotating shaft 21 to rotate on the frame body 11 at this time. The rotation of the rotating shaft 21 polishes the curved surface to be detected of the lip brick, so that the dirt on the surface of the curved surface to be detected of the lip brick is removed.

[0065] In addition, when the first output shaft of the double-output shaft motor 13 rotates, the rotating rod 53 synchronously rotates with the first output shaft. The rotation of the rotating rod 53 makes the sliding shaft 55 slide periodically along the corrugated groove 531. In the sliding process of the sliding shaft 55, the linear frame 54 makes reciprocating linear motion in the sliding cylinder 52. Then, the piston 561 makes linear reciprocating motion in the air cylinder 56 through the connecting rod. At this time, the gas outside the air cylinder 56 enters the air cylinder 56 through the one-way valve one. Then, the gas in the air cylinder 56 enters the upper cavity of the pressure tank 51 through the one-way valve two under the action of the piston 561.

[0066] As the gas continues to enter the upper cavity of the pressure tank 51, the gas pressure in the upper cavity of the pressure tank 51 increases. The lifting plate 57 starts to shift towards the lower cavity under the action of the gas pressure. The spring one deforms. When the lifting plate 57 shifts to the appropriate position, the compressed gas in the upper cavity enters the rotating groove 24 through the air pipe at this time. Then, the compressed gas in the rotating groove 24 is sprayed out of the opening at the end of the rotating shaft 21 through the air jet pipe 25. Because the flow path of the compressed gas in the rotating groove 24 into the air jet pipe 25 is reduced, the flow rate of the gas after passing through the air jet pipe 25 will be further improved. Then, the high-speed airflow sprayed out of the air jet pipe 25 will flush the surface of the lip brick during polishing.

[0067] When the lip brick is polished, the conveying line 1 will convey the polished lip brick to the area position of the coating unit 12, when the lip brick contacts the coating unit 12, the drainage ball 17 will contact the curved surface to be coated of the lip brick, at the same time, the lip brick will press the drainage ball 17 and the telescopic rod slides along the limiting rod, at this time, the spring II is deformed, the drainage ball 17 no longer blocks the water outlet hole, and the permeate in the storage box 15 can be discharged through the water outlet hole;

[0068] When the lip brick is displaced by the conveying line 1, the drainage ball 17 is rotated under the action of the lip brick, the rotation of the drainage ball 17 will guide the permeate in the storage box 15 to be discharged from the water outlet hole, so that the permeate is coated on the curved surface to be detected of the lip brick;

[0069] The lip brick coated with the permeate needs to be placed for a period of time, so that the permeate can fully penetrate into the pores or cracks of the lip brick, and then the excess permeate on the curved surface to be detected is manually wiped off with a cleaning cloth, and then the developer is manually sprayed towards the lip brick to be detected, finally, the lip brick to be detected is placed in a suitable environment, and the area to be detected of the lip brick is irradiated by the ultraviolet lamp, so that the cracks of the area to be detected of the lip brick are observed.

[0073] During use, when the double-output shaft motor 13 drives the polishing unit 2 to polish the surface of the lip brick, high-speed fluid is discharged through the air jet pipe 25 and washes the dust on the surface of the lip brick, at this time, the dust generated by polishing on the lip brick will be affected by the fluid and fly;

[0074] When the double-output shaft motor 13 is running, the second output shaft on it will drive the fan 33 to rotate, and the rotation of the fan 33 will guide the surrounding gas to flow towards the direction of the collecting cylinder 41, and then the gas in the area of the dust collecting cover 31 will be pulled by the traction force when the fan 33 rotates;

[0081] During use, when the second output shaft of the double-output shaft motor 13 rotates, the dust generated by polishing on the lip brick will follow the fluid into the gas collecting box 32, and then into the collecting cylinder 41 from the gas collecting box 32;

[0082] When the fan 33 rotates, the centrifugal tube 42 and the drainage plate 43 outside the centrifugal tube 42 also rotate synchronously. When the dust particles follow the fluid through the collection cylinder 41, the dust particles in the fluid contact the surface of the drainage plate 43 and the inner wall of the filter cylinder 44. During the rotation of the centrifugal tube 42 and the drainage plate 43, the water in the water tank 46 first enters the centrifugal cavity and the drainage cavity under the action of gravity. When the centrifugal tube 42 and the drainage plate 43 rotate, the water in the centrifugal cavity enters the drainage cavity under the action of centrifugal force, and the water in the drainage cavity is discharged through the drainage hole under the action of centrifugal force. At this time, the surface of the drainage plate 43 is attached to a layer of water film. When the fluid passes through the collection cylinder 41, the dust particles in the fluid contact the drainage plate 43, so that the dust particles in the fluid are adsorbed by the water;

[0083] After the dust particles contact and mix with the water, sewage is generated. The sewage on the surface of the drainage plate 43 gradually separates from the drainage plate 43 under the action of centrifugal force and is blocked by the collection cylinder 41. Finally, the sewage collects at the bottom of the collection cylinder 41 and flows onto the guide plate 45, and then enters the filter cylinder 44 through the guide plate 45. The sewage entering the filter cylinder 44 first passes through the filter plate 48. The dust particles or particulate matter in the sewage are intercepted by the filter plate 48. After the water passes through the filter plate 48, it mixes with the water at the bottom of the filter cylinder 44.

[0084] When the water in the water tank 46 is gradually discharged through the drainage hole, the pressure inside the water tank 46 decreases, so that the water in the filter cylinder 44 enters the water tank 46 through the backflow pipe 47 under the action of negative pressure.

[0085] The remaining structure is the same as that of example 2.

[0086] Example 4, refer to Figures 1-10 As a fourth embodiment of the present application, a detection method of a lip brick crack detection device for photovoltaic glass is provided, comprising the following steps,

[0087] S1, first, place the lip brick to be detected on the conveying line 1, then the conveying line 1 transports the lip brick to the polishing unit 2 area position, and the double-output shaft motor 13 drives the polishing piece 23 to polish the lip brick;

[0088] S2, at the same time, the first output shaft of the double-output shaft motor 13 drives the rotating rod 53 to rotate, so that the sliding shaft 55 slides along the corrugated groove 531. During the sliding of the sliding shaft 55, the linear frame 54 makes reciprocating linear motion in the sliding cylinder 52, so that the piston 561 makes linear reciprocating motion in the air cylinder 56. At this time, the gas outside the air cylinder 56 enters the air cylinder 56 through the one-way valve I, and then the gas in the air cylinder 56 enters the upper cavity of the pressure tank 51 through the one-way valve II under the action of the piston 561;

[0089] S3, as the gas pressure inside the upper chamber of the pressure tank 51 increases, the lifting plate 57 begins to shift towards the lower chamber under the action of the gas pressure, until the lifting plate 57 is shifted to the appropriate position, then the compressed gas inside the upper chamber enters the rotating groove 24 through the gas pipe, and then the compressed gas in the rotating groove 24 is sprayed out of the opening at the end of the rotating shaft 21 away from the rotating shaft 21 through the air jet pipe 25;

[0090] S4, the flow path of the compressed gas entering the air jet pipe 25 in the rotating groove 24 is reduced, causing the flow rate of the gas after passing through the air jet pipe 25 to increase, and then the high-speed airflow sprayed out of the air jet pipe 25 will scour the surface of the lip brick during the grinding process;

[0091] S5, after the lip brick is ground, the conveying line 1 conveys the ground lip brick to the area position of the coating unit 12, then the drainage ball 17 contacts the surface of the lip brick to be coated, and the lip brick presses the drainage ball 17 and the telescopic rod to slide along the limiting rod, then the drainage ball 17 no longer blocks the water outlet hole, and the permeate in the storage box 15 can be discharged through the water outlet hole;

[0092] S6, when the lip brick is shifted, the drainage ball 17 is rotated under the action of the lip brick, and the rotation of the drainage ball 17 guides the permeate in the storage box 15 to be discharged from the water outlet hole, so that the permeate is coated on the curved surface of the lip brick to be detected;

[0093] S7, the lip brick coated with the permeate needs to be placed for a period of time, so that the permeate can fully penetrate into the pores or cracks of the lip brick, then the excess permeate on the curved surface to be detected is manually wiped off with a cleaning cloth, then the developer is manually sprayed towards the area to be detected of the lip brick, and finally the lip brick to be detected is placed in a suitable environment, and the area to be detected of the lip brick is irradiated by the ultraviolet lamp, so that the cracks in the area to be detected of the lip brick are observed;

[0094] S8, when the double-output-shaft motor 13 is running, the second output shaft thereon drives the fan 33 to rotate, the rotation of the fan 33 guides the surrounding gas to flow towards the collecting cylinder 41, then the gas in the area of the dust collecting cover 31 is subjected to the traction force when the fan 33 rotates, then the flying dust particles follow the fluid from the dust collecting cover 31 into the gas collecting tank 32, and finally into the collecting cylinder 41;

[0095] S9, when the fan 33 rotates, the centrifugal pipe 42 and the drainage plate 43 outside the centrifugal pipe 42 also rotate synchronously, the dust particles in the fluid contact the surface of the drainage plate 43 and the inner wall of the filter cylinder 44, and at this time the water in the centrifugal cavity enters the drainage cavity under the action of the centrifugal force, the water in the drainage cavity is discharged from the drainage hole under the action of the centrifugal force, and at this time the surface of the drainage plate 43 is attached with a layer of water film, and the dust particles in the fluid are adsorbed by the water when the fluid passes through the collecting cylinder 41;

[0096] S10, the dust particles are mixed with the water body to generate sewage, which is collected at the bottom of the collecting cylinder 41 and flows onto the guide plate 45 and then enters the filtering cylinder 44 through the guide plate 45. The sewage entering the filtering cylinder 44 first passes through the filtering plate 48, and the dust particles or particulate matters in the sewage are intercepted by the filtering plate 48. After the water body passes through the filtering plate 48, it is mixed with the water body at the bottom of the filtering cylinder 44;

[0097] S11, when the water body in the water tank 46 is gradually discharged through the drain hole, the pressure inside the water tank 46 decreases, causing the water body inside the filtering cylinder 44 to enter the water tank 46 through the backflow pipe 47 under the action of negative pressure.

During the sliding of the sliding shaft (55), the linear frame (54) performs a reciprocating linear motion in the sliding cylinder (52), so that the piston (561) performs a linear reciprocating motion in the gas cylinder (56). At this time, the gas outside the gas cylinder (56) enters the gas cylinder (56) through the one-way valve 1, and then the gas in the gas cylinder (56) enters the upper chamber of the pressure box (51) through the one-way valve 2 under the action of the piston (561); As the gas pressure inside the upper chamber of the pressure box (51) increases, the lifting plate (57) begins to shift toward the lower chamber under the action of the gas pressure until the lifting plate (57) shifts to an appropriate position, and the compressed gas inside the upper chamber enters the rotating groove (24) through the gas pipe, and then the compressed gas in the rotating groove (24) is ejected through the opening of the jet pipe (25) at one end away from the rotating shaft (21); The compressed gas in the rotating tank (24) has a reduced flow path when entering the air jet pipe (25), causing the flow rate of the gas to increase after passing through the air jet pipe (25). Then, the high-speed airflow ejected from the air jet pipe (25) will flush the surface of the lip brick during the grinding process. After the lip brick is polished, the conveyor line (1) conveys the polished lip brick to the area of ​​the coating unit (12), and then the drainage ball (17) contacts the curved surface of the lip brick to be coated. At the same time, the lip brick presses the drainage ball (17) and the telescopic rod to slide along the limit rod, and then the drainage ball (17) no longer blocks the water outlet hole, and the permeate in the storage box (15) can be discharged through the water outlet hole; When the lip brick is displaced, the drainage ball (17) rotates under the action of the lip brick, and the rotation of the drainage ball (17) guides the permeate in the storage box (15) to be discharged from the water outlet, so that the permeate is applied to the curved surface of the lip brick to be tested; The lip brick coated with the penetrant needs to be left to stand for a period of time to allow the penetrant to fully penetrate the pores or cracks of the lip brick. Then, the excess penetrant on the surface of the to-be-tested curved surface is manually wiped off with a cleaning cloth. Then, the developer is manually sprayed on the to-be-tested area of ​​the lip brick. Finally, the to-be-tested lip brick is placed in an appropriate environment and the to-be-tested area of ​​the lip brick is illuminated by an ultraviolet lamp to observe the cracks in the to-be-tested area of ​​the lip brick. When the dual-output shaft motor (13) is running, the second output shaft thereon drives the fan (33) to rotate, and the rotation of the fan (33) guides the surrounding gas to flow toward the collecting tube (41), and then the gas in the dust collecting hood (31) area is subjected to the traction force of the fan (33) when it rotates, and then the flying dust particles follow the fluid from the dust collecting hood (31) into the gas collecting box (32), and finally enter the collecting tube (41) from the gas collecting box (32); When the fan (33) rotates, the centrifugal tube (42) and the drainage plate (43) outside the centrifugal tube (42) will also rotate synchronously, and the dust particles in the fluid will contact the surface of the drainage plate (43) and the inner wall of the filter cylinder (44). At this time, the water in the centrifugal chamber enters the drainage chamber under the action of centrifugal force, and the water in the drainage chamber is discharged from the drainage hole under the action of centrifugal force. At this time, a layer of water film is attached to the surface of the drainage plate (43). When the fluid passes through the collection cylinder (41), the dust particles in the fluid will be adsorbed by the water. Dust particles come into contact with water and mix to produce sewage. The sewage will gather at the bottom of the collection tube (41) and flow onto the guide plate (45). Then, it will pass through the guide plate (45) and enter the filter tube (44). The sewage entering the filter tube (44) will first pass through the filter plate (48). Dust particles or particulate matter in the sewage will be intercepted by the filter plate (48). After the water passes through the filter plate (48), it will mix with the water at the bottom of the filter tube (44). When the water in the water tank (46) is gradually discharged from the drain hole, the pressure inside the water tank (46) decreases, causing the water inside the filter cartridge (44) to enter the water tank (46) through the return pipe (47) under the action of negative pressure.
