Description

Technical Field

[0001] This invention relates to the field of oil fume generating device technology, and more specifically, to a capillary cleaning system and method for oil fume generating devices that uses dripping water and oil. Background Technology

[0002] Oil fume generators are mainly used for testing and calibration of products such as oil fume monitors. Specifically, they generate continuous and stable oil fumes by quantitatively adding cooking oil and water to a heating evaporation module. Currently, the lower end of the capillary tube used in existing oil and water generators is generally located directly above the heating dish. Over time, oil inevitably enters the capillary tube, causing blockage. Blockage prevents the dripping of oil or water into the heating dish, hindering the generation of stable oil fumes and potentially leading to burnt food. However, current technology cannot automatically and thoroughly clean the capillary tube; it must be removed and replaced, significantly reducing its utilization rate. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a system and method for cleaning the capillary tubes of an oil fume generator. This system features an internal and external cleaning structure that automatically cleans the dirt inside and outside the inclined drip tube after blockage, thereby reducing the frequency of replacing the capillary tubes and improving their utilization rate.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A capillary cleaning system for dripping water and oil from an oil fume generator includes an oil fume generating chamber, a suction pipe fixedly installed on the side of the oil fume generating chamber, a display panel on the front of the oil fume generating chamber, an electrically connected controller to the display panel, two inclined drip tubes arranged vertically and horizontally on the inner wall of the oil fume generating chamber away from the suction pipe, and two connecting pipes fixedly connected to the inner wall of the oil fume generating chamber near the inclined drip tubes, with a communication mechanism between the connecting pipes and the inclined drip tubes; Both connecting pipes extend beyond the outer surface of the fume generator housing at their ends away from the inclined drip pipe. Two suction pumps are fixedly connected to the side of the fume generator housing away from the suction pipe. The ends of the two connecting pipes outside the fume generator housing are connected to the output ports of the two suction pumps, respectively. Four horizontally arranged liquid storage tanks are fixedly connected to the surface of the fume generator housing away from the suction pipe. Two of the liquid storage tanks contain oil and water, respectively, while the two outer liquid storage tanks contain cleaning agent. Two T-joints are fixedly connected to the surface of the fume generator housing away from the suction pipe. The three ports of the T-joints are connected to the suction pipes on the two liquid storage tanks and the suction port pipes of the suction pumps, respectively. A solenoid valve is installed at the end of the suction pipe of the liquid storage tank near the T-joint. The solenoid valve and the suction pump are electrically connected to the controller. A hydraulic sensor for detecting pressure changes in the connecting pipe is installed at the end of the connecting pipe near the suction pump. The hydraulic sensor is electrically connected to the controller. An external cleaning mechanism is installed inside the fume generator housing, and a detection mechanism located behind the connecting pipe is installed on the outer surface of the fume generator housing.

[0005] A method for cleaning a fume generator that generates dripping water and oil using a capillary tube includes the following steps: S1. When the hydraulic sensor detects that the pressure inside the tilted drip tube exceeds the pressure threshold, the controller determines that the tilted drip tube is blocked and the heating module stops operating. S2. Control the tilting dropper to rotate forward, and close the solenoid valve connected to the oil or water reservoir at the corresponding position. Open the other solenoid valve connected to the reservoir for storing cleaning fluid. The suction pump draws the cleaning fluid into the blocked tilting dropper, where the cleaning fluid reacts chemically with the dirt in the tilting dropper. S3. While performing S2, the ultrasonic cleaner is pushed into the fume generator box. After being pushed in, the ultrasonic cleaner is pushed upward so that the lower end of the inclined dropper is immersed in the cleaning solution of the ultrasonic cleaner. The ultrasonic cleaner is activated and uses ultrasonic waves to clean the dirt on the lower end of the inclined dropper and its outer surface. S4. If the pressure detected by the hydraulic sensor still exceeds the pressure threshold, the tilting dropper rotates backward and becomes parallel to the detection groove. At this time, the backscatter X-ray machine is controlled to slide along the inclined surface of the detection groove and scan the tilting dropper synchronously. The scanned image is transmitted to the display panel. When the tilting dropper is blocked, the alarm will sound to remind the staff, and the display panel will show the blockage location inside the tilting dropper. At the same time, it will show three options: continue cleaning, cut, or replace the tilting dropper. The staff can choose according to the actual situation and their own needs to complete the subsequent operation.

[0006] The advantages of this invention are: Firstly, by setting up internal and external cleaning structures and hydraulic sensors, this invention can automatically detect the degree of blockage in the tilted dropper. After blockage, the internal and external cleaning structures automatically clean the dirt inside and outside the tilted dropper, thereby reducing the number of times the capillary tube for water and oil dripping is replaced when blockage occurs and improving the utilization rate of the capillary tube for water and oil dripping.

[0007] Secondly, by incorporating an X-ray scanning mechanism, this invention can scan the internal blockage of the tilted dropper using X-ray technology when dirt cannot be removed, providing staff with a basis for judgment and allowing for the cutting or replacement of the tilted dropper, thus avoiding the need to directly replace the tilted dropper.

[0010] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0011] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0012] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0013] Please see Figure 1-12 The present invention provides the following technical solutions: Specifically, it refers to a capillary cleaning system for dripping water and oil from an oil fume generator, comprising an oil fume generating chamber 1. The front of the oil fume generating chamber 1 has two doors 5, which are connected to the front of the chamber 1 via hinges. Therefore, when the two doors 5 are closed, the interior of the oil fume generating chamber 1 is blocked. A suction pipe 2 is fixedly installed on the side of the oil fume generating chamber 1, and the suction pipe 2 is interconnected with the interior of the oil fume generating chamber 1. An exhaust fan 6 is installed inside the suction pipe 2 near the oil fume generating chamber 1, and an oil fume purification device is installed at the end of the suction pipe 2 away from the oil fume generating chamber 1. The outer surface of one end of the suction pipe 2 is respectively equipped with a fume monitor 3 and a fume calibration standard 4. The detection ports of both the fume monitor 3 and the fume calibration standard 4 are connected to the inside of the suction pipe 2. Therefore, when in use, by starting the exhaust fan 6, the exhaust fan 6 draws the fume in the fume generating box 1 into the suction pipe 2. At this time, the fume monitor 3 and the fume calibration standard 4 detect the fume in the suction pipe 2 respectively. Thus, the detection values ​​of the fume monitor 3 and the fume calibration standard 4 can be used to determine whether the fume monitor 3 is normal.

[0014] Furthermore, a ventilation plate 7 extending into the fume generating chamber 1 is embedded on the side of the chamber away from the suction pipe 2. This allows external air to enter the fume generating chamber 1 through the ventilation plate 7 during suction, facilitating the extraction of fumes. Two limiting slide plates 71 are fixedly connected to the surface of the fume generating chamber 1 near the ventilation plate 7. The two limiting slide plates 71 are located on the upper and lower sides of the ventilation plate 7, respectively. A shielding plate 72 that can block the ventilation plate 7 is slidably connected between the two limiting slide plates 71. A groove 73 is provided on the opposite surface of the two limiting slide plates 71. A slider 74 that slides in the groove 73 is fixedly connected to the surface of the shielding plate 72 near the groove 73. When suction is performed, the shielding plate 72 can be slid away from the ventilation plate 7, so that the shielding plate 72 no longer blocks the ventilation plate 7.

[0015] Furthermore, a display panel 11 is provided on the front of the fume generating box 1, and the display panel 11 is electrically connected to a controller. A heating module 12 is installed on the bottom wall of the fume generating box 1. The heating module 12 is a heating device such as an induction cooker. The heating module is electrically connected to the controller. A heating barrel 13 is placed on the heating module 12. Therefore, the heating temperature and heating time of the heating module 12 can be set by the controller.

[0016] Furthermore, two inclined drip tubes 14, parallel to each other, are installed on the inner wall of the fume generator 1 away from the suction pipe 2. The inclined drip tubes 14 are made of stainless steel, and their lower ends are located above the heating tank 13. Two connecting pipes 16 are fixedly connected to the inner wall of the fume generator 1 near the inclined drip tubes 14, and a communication mechanism is provided between the connecting pipes 16 and the inclined drip tubes 14. The ends of the two connecting pipes 16 away from the inclined drip tubes 14 extend through the outer surface of the fume generator 1. Two suction pumps 18 are fixedly connected to the surface of the fume generator 1 away from the suction pipe 2. The ends of the two connecting pipes 16 outside the fume generator 1 are respectively connected to the output ports of the two suction pumps 18. Four... Two horizontally arranged liquid storage tanks 112 are provided. The two middle liquid storage tanks 112 contain oil and water respectively. Two suction pumps 18 are located above the oil storage tank 112 and the water storage tank 112 respectively. The two outer liquid storage tanks 112 contain cleaning agent, which is a pre-existing dirt cleaner. Two T-joints 110 are fixedly connected to the surface of the oil fume generator 1 away from the suction pipe 2. Suction pipes that penetrate into the liquid storage tank 112 are fixedly installed on each liquid storage tank 112. The three ports of the T-joints 110 are respectively connected to the suction pipes on the two liquid storage tanks 112 and the suction port pipe of the suction pumps 18. A solenoid valve 111 is provided at the end of the suction pipe of the liquid storage tank 112 near the T-joints 110. The solenoid valve 111 and the suction pumps 18 are electrically connected to the controller.

[0017] When oil fumes are needed, the controller starts the heating module 12 and simultaneously opens the solenoid valves on the oil and water storage tanks 112. After opening, the suction pumps 18 start synchronously, so that the two suction pumps 18 draw oil and water into the upper and lower inclined drip pipes 14 respectively. Since the lower ends of the two inclined drip pipes 14 are located above the heating tank 13, the oil and water drip into the heating tank 13 respectively, thereby heating the oil and water mixture in the heating tank 13, thus generating oil fumes in the oil fume generating chamber 1.

[0018] Furthermore, the connecting mechanism includes an installation tube 141, which is located at the upper end of the inclined dropper 14. The installation tube 141 and the inclined dropper 14 are installed and disassembled through a sealing threaded connection (see attached diagram). Figure 12 A metal hose 142 is fixedly connected between the installation pipe 141 and the connecting pipe 16. Therefore, when oil or water is being transported, the liquid in the connecting pipe 16 enters the inclined dropper 14 through the metal hose 142 and the installation pipe 141.

[0019] Furthermore, a control housing 143 is provided on the upper side of the mounting pipe 141. One side of the control housing 143 is fixedly installed on the inner wall of the fume generating box 1. A rotating shaft 144 is fixedly connected to the upper surface of the mounting pipe 141. The upper end of the rotating shaft 144 rotates through into the control housing 143. A gear 145 is fixedly sleeved on the outer surface of the upper end of the rotating shaft 144. A rack 146 that slides on the bottom wall of the control housing 143 is meshed with the outer surface of the gear 145. A first electric push rod 147 is fixedly installed on the bottom wall of the control housing 143. One end of the telescopic rod of the first electric push rod 147 is fixedly connected to the rack 146. The first electric push rod 147 is electrically connected to the controller.

[0020] When in use, when it is necessary to control the rotation of the tilting dropper 14, the controller controls the first electric push rod 147, which can drive the rack 146 to move back and forth, so that the rack 146 can mesh with the transmission gear 145 to rotate, thereby controlling the tilting dropper 14 to rotate forward or backward.

[0021] Furthermore, a hydraulic sensor 19 for detecting pressure changes in the connecting pipe 16 is provided at one end of the connecting pipe 16 near the suction pump 18. The hydraulic sensor 19 is electrically connected to the controller. The controller sets a pressure threshold in the connecting pipe 16. When a blockage occurs in the inclined dropper 14, the pressure in the connecting pipe 16 will exceed the pressure threshold, and the heating module 12 will stop operating. At the same time, the controller controls the first electric push rod 147 near the blocked inclined dropper 14 to start. The first electric push rod 147 controls the blocked inclined dropper 14 to rotate forward. At the same time, the solenoid valve 111 connected to the oil and water storage tanks 112 is closed, while the solenoid valve 111 connected to the cleaning fluid storage tank is opened. At the same time, the suction pump 18 connected to the blocked inclined dropper 14 is turned on, so that the cleaning fluid can be drawn into the blocked inclined dropper 14. The cleaning fluid reacts chemically with the dirt in the inclined dropper 14, thereby completing the cleaning of the dirt inside the inclined dropper 14.

[0022] Furthermore, an external cleaning mechanism 15 is provided inside the fume generating chamber 1. The external cleaning mechanism 15 includes a lifting plate 151, which is located in front of the inclined drip pipe 14. The lower surface of the lifting plate 151 has a lifting housing 152 fixedly installed on the bottom wall of the fume generating chamber 1. A hydraulic cylinder (not shown in the figure) is provided inside the lifting housing 152. The upper end of the extension rod of the hydraulic cylinder slides through the upper surface of the lifting housing 152 and is fixedly connected to the lower surface of the lifting plate 151. A baffle plate 153 is provided on the upper side of the lifting housing 152. A sliding hole 1514 communicating with the interior of the lifting housing 152 is opened on the side of the lifting housing 152 away from the suction pipe 2. The outer surface of the baffle plate 153 is in contact with the inner wall of the sliding hole 1514. One side of the baffle plate 153 extends out of the outer surface of the fume generating chamber 1 through the sliding hole 1514. An external mounting plate 154 is fixedly connected to the outer surface of the fume generating box 1 near the baffle plate 153. The external mounting plate 154 is located below the baffle plate 153. An ultrasonic cleaner 155 that slides on the external mounting plate 154 is fixedly connected to the outer surface of the baffle plate 153 on the outside of the fume generating box 1. A second electric push rod 156 is fixedly installed on the external mounting plate 154. A push block 157 is fixedly connected to the outer surface of the ultrasonic cleaner 155 facing the second electric push rod 156. A T-shaped groove 158 is opened on the surface of the push block 157 facing away from the ultrasonic cleaner 155. A T-shaped slider 159 that slides in the T-shaped groove 158 is fixedly connected to one end of the telescopic rod of the second electric push rod 156 near the push block 157. The hydraulic cylinder, the second electric push rod 156 and the ultrasonic cleaner 155 are all electrically connected to the controller.

[0023] In use, cleaning fluid is poured into the ultrasonic cleaner 155. When the inclined dropper 14 becomes clogged, the inclined dropper 14 rotates forward. At this time, the second electric push rod 156 is activated and pushes the baffle plate 153 and the ultrasonic cleaner 155 through the sliding hole 1514 into the fume generator box 1. When the ultrasonic cleaner 155 slides completely above the lifting plate 151, the hydraulic cylinder is activated and pushes the lifting plate 151 upward. At the same time, the T-shaped slider 159 slides in the T-shaped groove 158, so that the lower end of the inclined dropper 14 is immersed in the cleaning fluid of the ultrasonic cleaner 155. At the same time, the ultrasonic cleaner 155 is activated and uses ultrasound to clean the dirt on the lower end and outer surface of the inclined dropper 14. Through the external cleaning mechanism 15 and the injection of cleaning fluid into the inclined dropper 14, the dirt inside and outside the inclined dropper 14 is cleared, thereby reducing the number of times the dripping capillary tube is replaced when clogged and improving the utilization rate of the dripping capillary tube.

[0024] In this embodiment, a sealing rubber gasket is provided on the outer surface of the baffle plate 153, which increases the sealing between the baffle plate 153 and the sliding hole 1514 and prevents the problem of oil fume leakage when the baffle plate 153 blocks the sliding hole 1514.

[0025] Furthermore, a drive housing 1511 is fixedly connected to the inner wall of the ultrasonic cleaner 155. Two cleaning shafts 1510 are rotatably connected between the surface of the drive housing 1511 and the inner wall of the other side of the ultrasonic cleaner 155. A wire brush is fixedly connected to the outer surface of the cleaning shaft 1510. One end of the cleaning shaft 1510 near the drive housing 1511 rotatably penetrates into the drive housing 1511 and is rotatably connected to the inner wall of the drive housing 1511. The outer surface of the two cleaning shafts 1510 located inside the drive housing 1511 is fixedly connected to the drive housing 1511. The fixed sleeve is equipped with two meshing synchronous gears 1512. The outer surface of the ultrasonic cleaner 155 is fixedly connected to the cleaning motor 1513. One end of the output shaft of the cleaning motor 1513 rotates through the drive housing 1511 and is fixedly connected to the end of the cleaning shaft 1510 near the side of the cleaning motor 1513. When the lower end of the inclined dropper 14 is inserted into the ultrasonic cleaner 155, the lower end of the inclined dropper 14 can rotate above the two cleaning shafts 1510. The cleaning motor 1513 is also electrically connected to the controller.

[0026] When the ultrasonic cleaner 155 is started, the cleaning motor 1513 starts synchronously, thereby driving one cleaning shaft 1510 to rotate. Since the two synchronous gears 1512 mesh with each other, the two synchronous gears 1512 rotate in opposite directions. The two cleaning shafts 1510 respectively drive the wire brushes on their surfaces to rotate in opposite directions, thereby adding brushing cleaning to the ultrasonic cleaning of the bottom of the inclined dropper 14, further improving the cleaning effect on the dirt at the bottom of the inclined dropper 14.

[0027] Furthermore, a detection mechanism 17 is provided on the outer surface of the fume generating box 1, located behind the connecting pipe 16. The detection mechanism 17 includes an outer cover 171, which is fixedly installed on the outer surface of the fume generating box 1. A detection groove 172 communicating with the interior of the fume generating box 1 is opened on the outer surface of the fume generating box 1 inside the outer cover 171. The inclination angle of the detection groove 172 is the same as the inclination angle of the inclined drip tube 14. A third electric push rod 174 is fixedly connected to the upper surface of the outer cover 171. The lower end of the telescopic rod of the third electric push rod 174 slides through into the outer cover 171. A mouth-shaped push plate 175 is fixedly connected to the lower end of the telescopic rod of the third electric push rod 174. A back is slidably connected to the inner side of the mouth-shaped push plate 175. The backscatter X-ray machine 176 is an existing model: HBI-120LC handheld backscatter X-ray machine. The third electric push rod 174 and the backscatter X-ray machine 176 are electrically connected to the controller. The emitting end of the backscatter X-ray machine 176 extends into the detection chute 172. The outer surface of the end of the backscatter X-ray machine 176 located in the detection chute 172 is rotatably fitted with a roller 179 that slides in the detection chute 172. The inner walls of the upper and lower sides of the mouth-shaped push plate 175 are provided with transverse sliding grooves 177. A transverse slider 178 that slides in the transverse sliding groove 177 is fixedly connected to the surface of the backscatter X-ray machine 176 near the transverse sliding groove 177. An alarm is installed on the fume generating box 1, and the alarm is electrically connected to the controller.

[0028] After the inclined dropper 14 has been cleaned by the cleaning mechanism for a period of time, if the pressure detected by the hydraulic sensor 19 still exceeds the pressure threshold, the inclined dropper 14 rotates backward to be parallel to the detection chute 172. At the same time, the third electric push rod 174 pushes the mouth-shaped push plate 175 downward, and the backscatter X-ray machine 176 starts synchronously. Because the backscatter X-ray machine 176 is restricted by the detection chute 172, it slides along the detection chute 172. At the same time, the transverse slider 178 slides in the transverse slide groove 177, so the backscatter X-ray machine 176 scans the inclined dropper 14 synchronously by sliding downward at an angle. The scanned image is simultaneously transmitted to the display panel 11. After the backscatter X-ray machine 176 completes the scan, the alarm sounds, and the display panel 11 displays the location of the blockage inside the inclined dropper 14 and shows three options: continue cleaning, cut, or replace the inclined dropper. The operator then selects the appropriate option based on the information displayed on the display panel 11. The device operates by selecting the option to continue cleaning. When the option to continue cleaning is selected, the device cleans the inside and outside of the tilted dropper 14 again and determines whether the tilted dropper 14 is blocked. If it is not blocked, it can continue to be used normally. If it is still blocked, the device will display three options: continue cleaning, cut, and replace. When the cut option is selected, the display panel 11 displays the irradiation image of the tilted dropper 14 after being scanned by the backscatter X-ray machine 176. The operator can determine the blockage position of the tilted dropper 14 based on the irradiation image and determine whether the tilted dropper 14 can be used normally after cutting. If it cannot be used normally, the operator can manually replace it with a new tilted dropper 14. With the above structure, when the dirt on the tilted dropper 14 cannot be removed, the X-ray technology can be used to scan the blockage inside the tilted dropper 14, providing the operator with a basis for determining the cutting position and cutting or replacing the tilted dropper 14. This avoids directly replacing the tilted dropper 14.

[0029] Furthermore, a swing shaft 1710 is rotatably connected between the inner walls of the two sides of the upper side of the detection chute 172. A cover plate 173 that can block the detection chute 172 is fixedly sleeved on the swing shaft 1710. A swing cavity 1711 is opened inside the side of the fume generating box 1 near the detection chute 172. One end of the swing shaft 1710 rotatably passes through the swing cavity 1711. A swing gear 1712 is fixedly connected to the end of the swing shaft 1710 located in the swing cavity 1711. A fourth electric push rod 1713 is fixedly connected to the outer surface of the fume generating box 1 near the swing cavity 1711. The fourth electric push rod 1713 is also electrically connected to the controller. One end of the telescopic rod of the fourth electric push rod 1713 slides through the swing cavity 1711. A swing rack 1714 that meshes with the swing gear 1712 is fixedly connected to the end of the telescopic rod of the fourth electric push rod 1713 located in the swing cavity 1711.

[0030] When scanning of the tilting dropper 14 is required, the fourth electric push rod 1713 pulls the swing rack 1714 to move. At this time, the swing rack 1714 engages and drives the swing gear 1712 to rotate. At the same time, the cover plate 173 rotates upward and no longer blocks the detection groove 172. The tilting dropper 14 is then rotated to be parallel to the detection groove 172. After the detection is completed, the tilting dropper 14 rotates forward, and the fourth electric push rod 1713 pushes the swing rack 1714 to move, thereby causing the cover plate 173 to rotate downward and block the detection groove 172. The above structure can prevent the oil fume in the oil fume generating box 1 from adhering to the backscatter X-ray machine 176 and affecting the scanning effect of the tilting dropper 14.

[0031] In this embodiment, a sealing rubber gasket is also provided on the outer surface of the cover plate 173, which increases the sealing performance of the cover plate 173 when blocking the detection groove 172.

[0032] Furthermore, a collar 148 is fitted onto the lower end of the inclined dropper 14, and the collar 148 is fixed to the inclined dropper 14 by bolts. A torsion cover plate 149 is hinged to the outer surface of the collar 148, and a torsion spring (not shown in the figure) is provided between the torsion cover plate 149 and the collar 148. When the torsion spring is in a free state, the torsion cover plate 149 is initially closed to the lower end of the inclined dropper 14 under the action of the torsion spring. A synchronization platform 1411 is fixedly connected to the upper surface of the rotating shaft 144, and a pull line 1410 is fixedly connected to the outer surface of the torsion cover plate 149. The upper end of the pull line 1410 slides through the rotating shaft 144 and eventually slides through the upper surface of the synchronization platform 1411. Multiple limiting rings are movably fitted onto the outer surface of the inclined dropper 14, and a sliding hole (see attached figure) is opened on the upper side of the limiting ring and is slidably fitted onto the outer surface of the pull line 1410. Figure 3 A torque motor 1412 is fixedly connected to the upper surface of the synchronous table 1411. A take-up wheel 1413 is fixedly connected to one end of the output shaft of the torque motor 1412. The upper end of the pull line 1410 is fixedly connected to the outer surface of the take-up wheel 1413. The torque motor 1412 is electrically connected to the controller.

[0033] When the inclined dropper 14 needs to drip water or oil, the torque motor 1412 starts and drives the take-up wheel 1413 to rotate. The take-up wheel 1413 winds up the tension line 1410, thereby pulling the other end of the tension line 1410 to rotate the torsion cover plate 149 away from the lower surface of the inclined dropper 14. At the same time, the torsion spring deforms, so the torsion cover plate 149 no longer blocks the lower end of the inclined dropper 14. When the device is finished, the torque motor 1412 stops running, the take-up wheel 1413 is no longer restricted, and the torsion spring pulls the torsion cover plate 149 to block the lower end of the inclined dropper 14 again.

[0034] The working principle of the capillary cleaning system for oil and water dripping of the fume generator provided by the present invention is as follows: When the inclined drip tube 14 is blocked, the pressure in the connecting pipe 16 will exceed the pressure threshold, the heating module 12 will stop running, and at the same time the controller controls the first electric push rod 147 near the blocked inclined drip tube 14 to start. The first electric push rod 147 controls the blocked inclined drip tube 14 to rotate forward. At the same time, the solenoid valve 111 connected to the oil and water storage tank 112 is closed, while the solenoid valve 111 connected to the cleaning liquid storage tank 112 is opened. At the same time, the suction pump 18 connected to the blocked inclined drip tube 14 is opened, so that the cleaning liquid can be drawn into the blocked inclined drip tube 14, and the cleaning liquid reacts chemically with the dirt in the inclined drip tube 14. At the same time, the second electric push rod 156 is activated and pushes the baffle plate 153 and the ultrasonic cleaner 155 into the fume generating box 1 through the sliding hole 1514. When the ultrasonic cleaner 155 slides completely above the lifting plate 151, the hydraulic cylinder is activated and pushes the lifting plate 151 upward. At the same time, the T-shaped slider 159 slides in the T-shaped groove 158, so that the lower end of the inclined drip tube 14 is immersed in the cleaning fluid of the ultrasonic cleaner 155. The ultrasonic cleaner 155 is activated and uses ultrasonic waves to clean the dirt on the lower end and outer surface of the inclined drip tube 14.

[0035] If the pressure detected by the hydraulic sensor 19 still exceeds the pressure threshold, the tilting dropper 14 rotates backward to be parallel to the detection groove 172. At the same time, the third electric push rod 174 pushes the mouth-shaped push plate 175 downward, and the backscatter X-ray machine 176 starts synchronously. Since the backscatter X-ray machine 176 is restricted by the detection groove 172, it slides along the detection groove 172. At the same time, the transverse slider 178 slides in the transverse groove 177. Thus, the backscatter X-ray machine 176 scans the tilting dropper 14 synchronously by sliding downward at an angle. At the same time, the scanned image is synchronously transmitted to the display panel 11. After the backscatter X-ray machine 176 finishes scanning, the alarm sounds, and the display panel 11 displays the location of the blockage inside the tilting dropper 14 and displays three options: continue cleaning, cut, or replace the tilting dropper.

[0036] The present invention provides a new technical solution based on the above-mentioned scheme: a capillary tube cleaning method for a fume generator that generates dripping water and oil, comprising the following steps: S1. When the hydraulic sensor 19 detects that the pressure inside the inclined drip tube 14 exceeds the pressure threshold, the controller determines that the inclined drip tube 14 is blocked and the heating module 12 stops operating. S2. Control the tilting dropper 14 to rotate forward, and the solenoid valve 111 connected to the oil or water storage tank 112 at the corresponding position is closed, and another solenoid valve 111 connected to the storage tank 112 for storing cleaning fluid is opened. The suction pump 18 draws the cleaning fluid into the blocked tilting dropper 14, and the cleaning fluid reacts chemically with the dirt in the tilting dropper 14. S3. While performing S2, the ultrasonic cleaner 155 is pushed into the fume generator box 1, the hydraulic cylinder is started, and the ultrasonic cleaner 155 is pushed upward, so that the lower end of the inclined dropper 14 is immersed in the cleaning fluid of the ultrasonic cleaner 155. The ultrasonic cleaner 155 is started, and the ultrasonic waves are used to clean the dirt on the lower end and outer surface of the inclined dropper 14. S4. If the pressure detected by the hydraulic sensor 19 still exceeds the pressure threshold, the tilting dropper 14 rotates to the rear and becomes parallel to the detection groove 172. At this time, the backscatter X-ray machine 176 is controlled to slide along the inclined surface of the detection groove 172 and scan the tilting dropper 14 synchronously. The scanned image is synchronously transmitted to the display panel 11. When the blockage position of the tilting dropper 14 is detected, the alarm is triggered to alert the staff, and the display panel 11 displays the blockage position inside the tilting dropper 14, and simultaneously displays three options: continue cleaning, cut, or replace the tilting dropper 14.
