[0031] The present invention will be further described below with reference to the accompanying drawings and some embodiments.

[0032] Figure 1-9 A fully automatic electrostatic oil fume purification integrated machine includes a fume hood housing 2, an oil fume purification device, and a cleaning device for cleaning the oil fume purification device. The oil fume purification device is connected to the top outer surface of the fume hood housing 2, and the cleaning device is located inside the oil fume purification device. The oil fume purification device includes a purification component for purifying large oil particles, an interception component for intercepting large oil particles, and a first fan 23. The interception component is disposed inside the fume hood housing 2 and fixed to the inner wall of the fume hood housing 2. The purification component includes a purification box 1, multiple first air distribution plates 7, and multiple electrostatic fields 3. The first air distribution plates 7 are respectively disposed at the air inlet 4 and air outlet 5 of the purification box 1, and the electrostatic fields 3 are arranged sequentially inside the purification box 1. The cleaning device is connected to the top outer surface of the fume hood housing 2, and one side is connected to the interception component through a duct, while the other side is connected to the first fan 23 through a duct. The first fan 23 is located on the duct. The cleaning device includes a sealing component 6 that can form a sealed cleaning chamber inside the purification box 1, and a cleaning component that can clean the electrostatic field 3 and the first air distribution plate 7. The sealing component 6 is located outside the first air distribution plate 7 and is fixed to the air inlet and outlet of the purification box 1. The cleaning component is located inside the cleaning chamber. The fume hood housing 2 is also equipped with a fresh air device that can blow air to the user to cool down. The fresh air device is independently installed inside the fume hood housing 2. A microcontroller 22 is provided outside the fume hood housing 2. The cleaning device and the fume purification device are electrically connected to the microcontroller 22.

[0033] In this embodiment, the interception component includes a second air distribution plate 49 and a third air distribution plate 51. The second air distribution plate 49 is disposed at the air inlet of the fume hood housing 2, and the third air distribution plate 51 is disposed above the fume hood housing 2. Both the second air distribution plate 49 and the third air distribution plate 51 are fixed to the inner wall of the fume hood housing 2. An air intake 50 is provided between the second air distribution plate 49 and the third air distribution plate 51. The purpose of setting up the interception component is to intercept oil fumes in multiple stages and effectively block large particles of oil fumes.

[0034] In this embodiment, the first air distribution plate 7, the second air distribution plate 49, and the third air distribution plate 51 are all wire mesh air distribution plates. The wire mesh air distribution plates are filled with stainless steel wires, and the mesh size is uneven. The advantage of using this kind of wire mesh air distribution plate is that the wire mesh air distribution plate filled with stainless steel wires can filter large oil droplets and water vapor in the fume with very low wind resistance, avoid the occurrence of electrostatic discharge at the tip of the electrostatic field 3, and extend the purification effect and effective purification cycle of the integrated fume purification machine.

[0035] In this embodiment, the first air distribution plate 7, the second air distribution plate 49, and the third air distribution plate 51 are all integral structures and can be easily disassembled.

[0036] In this embodiment, the first air distribution plate 7 is detachably connected to the air inlet 4 and air outlet 5 of the purification box 1, so that the first air distribution plate 7 can be periodically inspected for cleaning or damage. If the cleaning device fails to clean the first air distribution plate 7 or it is damaged, it can also be easily disassembled for cleaning or replacement. The second air distribution plate 49 and the third air distribution plate 51 are both detachably connected to the inner wall of the fume hood housing 2, and can be removed for easy cleaning.

[0037] In this embodiment, the electrostatic field 3 can be a plate electrostatic field or a honeycomb electrostatic field; the honeycomb electrostatic field and the plate electrostatic field are commonly used technical means in the prior art, and those skilled in the art should know them, so they will not be described in detail here.

[0038] In this embodiment, the plate electrostatic field structure can be further improved as follows: A high-voltage zone 30 and a low-voltage zone 31 are respectively provided at the air inlet and outlet surfaces of the plate electrostatic field. A high-voltage terminal 33 and multiple high-voltage connecting rods 32 are provided at the upper end of the high-voltage zone 30. The high-voltage connecting rods 32 are arranged horizontally opposite each other within the high-voltage zone 30. One end of each high-voltage connecting rod 32 passes through one side of the plate electrostatic field and can be connected to the high-voltage terminal 33; the other end is welded to the other side of the plate electrostatic field. A sawtooth discharge bar 34 extends vertically downwards to the bottom of the plate electrostatic field on the high-voltage connecting rod 32. The sawtooth discharge bars 34 on adjacent high-voltage connecting rods 32 are arranged opposite each other, and both sides of the sawtooth discharge bar 34 are provided with serrations 35. When the sawtooth discharge bars 34 are installed, the serrations 35 on adjacent sawtooth discharge bars 34 are in a relatively staggered position, ensuring uniform tip discharge and high discharge density among the multiple sawtooth discharge bars 34.

[0039] In this embodiment, the sawtooth discharge bar 34 has 2 to 3 rows.

[0040] In this embodiment, the sawtooth discharge row 34 is a sawtooth strip structure.

[0041] In this embodiment, the purpose of using the improved plate electrostatic field is that when the high-voltage terminal 33 is connected to a high-voltage current, the tip discharge between multiple sawtooth discharge bars 34 forms a more uniform high-voltage electrostatic field with a higher discharge density. The oil fumes enter from the air inlet surface of the electrostatic field 3 and first pass through the high-voltage zone 30. Under the action of the high-voltage electrostatic field, the oil fumes are ionized and charged. When the charged oil fume particles pass through the low-voltage zone 31 at the rear end, more oil fume particles can be intercepted and treated, achieving a better purification effect.

[0042] In this embodiment, the cleaning assembly includes a heating assembly that can heat water to assist in cleaning or heat air to dry water stains, a vibration assembly that can circulate water for oscillating cleaning, an additive assembly that adds water and detergent, and a wastewater discharge assembly that discharges wastewater. The heating assembly and vibration assembly are located on the inner wall of the fume hood shell, and the additive assembly is located on the outer wall of the fume hood shell. The additive assembly, wastewater discharge assembly, additive assembly, and vibration assembly are all electrically connected to the microcontroller 22.

[0043] In this embodiment, the dosing assembly includes a level sensor 8, a branch water pipe 20, a detergent tank 16, and a water-adding solenoid valve 14. The detergent tank 16 is connected to the outer wall of the purification tank 1. The level sensor 8 is located on the inner wall of the purification tank 1. The water-adding solenoid valve 14 is located at the upper end of the inner wall of the purification tank 1. The main end of the branch water pipe 20 is connected to the cleaning chamber, and the branch ends of the branch water pipe 20 are respectively connected to the detergent tank 16 and the water supply tank 17. A first electric valve 19 is provided at the connection between the water supply tank 17 and the branch water pipe 20, and a second electric valve 18 is provided at the connection between the detergent tank 16 and the branch water pipe 20. The water-adding solenoid valve 14 is located at the connection between the water pipe and the cleaning chamber. 19. The second electric valve 18 and the water-adding solenoid valve 14 are both connected to the output terminal of the microcontroller 22. Before cleaning, water and detergent need to be added. By opening the first electric valve 19, the second electric valve 18, and the water-adding solenoid valve 14, water and detergent are added to the cleaning chamber. At this time, the liquid level sensor 8 monitors the liquid level of the mixture in real time and transmits the sensing signal to the microcontroller 22 in real time. The microcontroller 22 converts the sensing signal into an electrical signal and outputs it to the first electric valve 19, the second electric valve 18, and the water-adding solenoid valve 14. When a certain value is reached, the first electric valve 19 and the second electric valve 18 close first, and then the water-adding solenoid valve 14 closes.

[0044] In this embodiment, water pumps can be installed at the connection points of the branch water pipe 20 with the water supply tank 17 and the detergent tank 16. In actual operation, water and detergent can be delivered into the cleaning chamber more quickly. The installation method of the water pump is the same as that of the water pump in the prior art, and will not be described in detail here.

[0045] In this embodiment, the sewage discharge assembly includes a sewage discharge solenoid valve 13 and a sewage collection tank 15. The sewage collection tank 15 can be placed on the ground and is connected to the bottom of the cleaning chamber through a water pipe. The sewage discharge solenoid valve 13 is located at the connection between the water pipe and the cleaning chamber. After cleaning is completed, the sewage discharge solenoid valve 13 is opened to discharge the sewage after cleaning and collect the sewage through the sewage collection tank 15.

[0046] In this embodiment, the vibration assembly includes an ultrasonic generator 11, a circulating water pump 12, and a timer 21. The ultrasonic generator 11 and the circulating water pump 12 are both located on the inner wall of the cleaning chamber, and the timer 21 is located inside the electrical box 2. The timer 21 is connected to the input terminal of the microcontroller 22, and the ultrasonic generator 11 and the circulating water pump 12 are both connected to the output terminal of the microcontroller 22.

[0047] In this embodiment, the heating assembly includes a temperature sensor 9 for detecting the temperature of the cleaning water and a heating rod 10 that can heat the air or the water. The temperature sensor 9 and the heater are both located on the inner wall of the cleaning chamber. The temperature sensor 9 is connected to the input terminal of the microcontroller 22, and the heating rod 10 is connected to the output terminal of the microcontroller 22. During the cleaning process, the circulating water pump 12 and the ultrasonic generator 11 are started, which can make the mixed liquid flow and generate vibration to achieve the expected cleaning effect.

[0048] In this embodiment, the fresh air device includes an independent air duct 24 and a second fan 25. The independent air duct 24 is connected to the inner wall of the fume hood housing 2, and the second fan 25 is located inside the air duct and fixed to the inner wall of the independent air duct 24. When the internal environment is hot, the fresh air switch 27 can be turned on. The fresh air switch 27 transmits an electrical signal to the microcontroller 22, and the microcontroller 22 outputs an electrical signal to the second fan 25, causing the second fan 25 to work and blow air into the room through the independent air duct 24 to cool the room.

[0049] In this embodiment, when timer 21 is started, cleaning and drying operations will begin. When timer 21 starts, microcontroller 22 receives the digital signal from timer 21 and converts it into an electrical signal, which is transmitted to the first electric valve 19, the second electric valve 18, and the water-adding solenoid valve 14. This causes the first electric valve 19, the second electric valve 18, and the water-adding solenoid valve 14 to inject water into the cleaning chamber. After water injection, microcontroller 22 controls the first electric valve 19, the second electric valve 18, and the water-adding solenoid valve 14 to close. Then, microcontroller 22 outputs an electrical signal to heating rod 10 to heat the water. After heating, microcontroller 22 controls heating rod 10 to close. Then, microcontroller 22 outputs an electrical signal to circulating water pump 12 and ultrasonic generator 11 to operate, causing the mixed liquid to flow and vibrate, cleaning the electrostatic field and the first air distribution plate. After cleaning for a certain period, microcontroller 22 receives the electrical signal from timer 21, causing circulating water pump 12 and ultrasonic generator 11 to operate, making the mixed liquid flow and vibrate, cleaning the electrostatic field and the first air distribution plate. After cleaning for a certain period, microcontroller 22 receives the electrical signal from timer 21, causing circulating water pump 12 and ultrasonic generator 11 to operate. 1. The system stops working and transmits an electrical signal to the drain solenoid valve 13, causing it to open and drain the internal sewage into the sewage collection tank 15. After the liquid level sensor 8 detects that the sewage has been drained, it closes the drain solenoid valve 13 and transmits a sensing signal to the microcontroller 22. The microcontroller 22 outputs an electrical signal to the first electric valve 19 and the water-adding solenoid valve 14, causing them to open and add clean water into the cleaning chamber. After adding clean water, the first electric valve 19 and the water-adding solenoid valve 14 close sequentially. Then, the cleaning process and the draining process after water injection are repeated. After the draining is completed, the sealing component 6 opens, and the microcontroller 22 outputs an electrical signal to the first fan 23 and the heating rod 10, causing the heating rod 10 and the first fan 23 to start simultaneously. While ventilating, the heating rod 10 can heat the air, speeding up the drying process and improving the drying effect. After drying is completed, the microcontroller 22 controls the heating rod 10 and the first fan 23 to close, and the oil fume purification device can operate normally.

[0050] In this embodiment, the sealing assembly 6 includes baffles 36, rotating plates 37, rotating shafts 38, rubber teeth 47, rubber strips 48, and a motor 39. Multiple baffles 36 are provided, each baffle 36 having its two ends sealed and fixed to the inner wall of the air inlet and outlet of the purification chamber 1, and are distributed parallel and equidistantly on the inner wall of the air inlet and outlet of the purification chamber 1. Each baffle 36 has arc-shaped rubber protrusions 40 at its upper and lower ends, forming a ventilation opening between adjacent baffles 36. Multiple rotating plates 37 are provided, each rotating plate 37 having a corresponding baffle tooth at its upper and lower ends. The rotating plate 37 is mounted on the ventilation opening via a rotating shaft 38. The rotating shaft 38 passes through the interior of the rotating plate 37 and is connected to the left and right ends of the inner wall of the air inlet and outlet of the purification box 1. One end of the rotating shaft 38 is rotatably connected to the motor 39. The rubber teeth 47 are provided at the left and right ends of each rotating plate 37. The left and right ends of the inner wall of the air inlet and outlet of the purification box 1 are provided with arc-shaped rubber strips 48 that can contact and seal with the rubber teeth 47. The motor 39 is built into the inner wall of the air inlet and outlet 5 of the purification box 1.

[0051] In this embodiment, the rubber protrusions 40, rubber grooves 41, rubber teeth 47, and rubber strips 48 are all made of soft rubber, the baffle 36 is made of metal or plastic material, each rotating shaft 38 is a lead screw, and the rotating plate 37 and rubber strips 48 are detachable.

[0052] In this embodiment, a protective cover 46 and a transmission device are also included to prevent oil stains from accumulating in the rubber groove 41. The protective cover 46 is located at both ends of the rotating plate 37 and cooperates with the opening of the rubber groove 41 to isolate the rubber groove 41 from the oil fumes. The transmission device includes a first worm gear 42, a second worm gear 43, a worm 44, and a rotating wheel 45 that drives the protective cover 46 to rotate. The first worm gear 42 is located on the rotating shaft 38 and is rotatably connected to the worm 44. The worm 44 is located in the rotating plate 37 and is rotatably connected to the second worm gear 43. The second worm gear 43 is rotatably connected to the rotating wheel 45. The rotating wheel 45 is rotatably connected to the protective cover 46.

[0053] In this embodiment, the rotating plate 37, driven by the rotating shaft 38, causes the rubber protrusion 40 to engage with the rubber groove 41. The rubber teeth 47 are squeezed and pressed against the rubber strip 48 during the rotation of the motor 39. A sealing structure can be formed by the engagement of the rubber teeth 47 and the rubber strip 48, and the engagement of the rubber groove 41 and the rubber protrusion 40.

[0054] In this embodiment, the rotation of the rotating shaft 38 drives the first worm gear 42 to rotate synchronously. The rotation of the first worm gear 42 drives the worm 44, the second worm gear 43 and the rotating wheel 45 to move, so that the protective cover 46 rotates with the rotation of the rotating plate 37, so that the protective cover 46 closes when the rotating plate 37 is open and opens when the rotating plate 37 is closed.

[0055] In this embodiment, when the fume purification equipment is working, the rotating plate 37 is arranged in a straight line at the air inlet 4 and the air outlet 5. When cleaning is performed, it needs to be sealed in advance. The sealing process is as follows: after the timer 21 is started, the microcontroller 22 receives the digital signal of the timer 21 and converts it into an electrical signal and transmits it to the motor 39. The motor 39 rotates, which drives the rotating plate 37 to rotate. At the same time, it drives the first worm gear 42, the worm 44, the second worm gear 43, and the rotating wheel 45 to rotate, so that the protective cover 46 flips into the cleaning chamber. The rubber protrusion 40 can be engaged in the rubber groove 41, and the rubber teeth 47 cooperate with the rubber strip 48, so that the baffle 36 and the rotating plate 37 together form a sealing structure to achieve the sealing effect.

[0056] In this embodiment, the protective cover 46 is provided to isolate the rubber groove 41 from the oil fumes, prevent the presence of oil residue in the rubber groove 41, and thus avoid affecting the sealing performance of the sealing structure. After the sealing structure is formed by rotation, the protective cover 46 is located in the cleaning chamber and can also be cleaned by the cleaning device.

[0057] In this embodiment, a lighting lamp 54 is provided at the lower end of the smoke hood shell 2, which can illuminate the room in dim conditions.

[0058] In this embodiment, the lower surface of the fume hood housing 2 is equipped with a cleaning switch 28, a lighting switch 52, a first fan switch 53, a fresh air switch 27, and a purification switch 26. The purification switch 26, fresh air switch 27, and purification switch 26 are all connected to the input terminal of the microcontroller 22. Pressing the fresh air switch 27 transmits an electrical signal to the microcontroller 22, which receives the signal and outputs an electrical signal to the second fan 25. The second fan 25 then operates, blowing air into the room along the independent duct 24 to cool it down. Pressing the purification switch 26 causes the microcontroller 22 to receive the signal and output an electrical signal to the electrostatic field 3 and the first fan 23, causing the first fan 23 and the electrostatic field 3 to operate simultaneously, purifying the fumes. Pressing the cleaning switch 28 starts the timer 21. Timer 21 transmits digital signals to microcontroller 22. Microcontroller 22 receives the digital signals and outputs electrical signals to motor 39, causing motor 39 to rotate. Rubber protrusion 40 can engage in rubber groove 41, and rubber teeth 47 cooperate with rubber strip 48 to form a sealing structure. Motor 39 stops working. Microcontroller 22 sequentially outputs electrical signals to additive assembly, cleaning assembly, and heating assembly, so that the electrostatic field 3, first air distribution plate 7, and second air distribution plate 29 in the cleaning chamber are effectively cleaned. The function of lighting switch 52 is that pressing lighting switch 52 can turn on lighting 54 for illumination. The function of first fan switch 53 is that it can turn on first fan 23 independently. If there is an odor in the room, it can exhaust air to the outside to dissipate the odor.

[0059] In this embodiment, when the fume purification equipment is working, the cleaning device is in a stopped state, which will not affect the normal use of the fume purification equipment; when the cleaning device is working, the fume purification equipment is in a stopped state, and the electrostatic field 3 is in a de-energized state.

[0060] In this embodiment, the microcontroller 22 is a programmable AT89C2051 or TMS320VC5509A single-chip microcomputer, etc.; the liquid level sensor 8 is an EE-SPX613 or E2K-L, etc.; the temperature sensor 9 is an HTU21D or SHT21, etc.; and the ultrasonic generator 11 is an ADS-M1 or TK-UG600, etc.

[0061] In this embodiment, the cleaning process inside the purification chamber 1 is as follows: First, the sealing component 6 is used to seal the inside of the purification chamber 1, forming a sealed cleaning chamber, sealing the electrostatic field 3 and the first air distribution plate 7 inside the cleaning chamber. The sealing process is as follows: After pressing the cleaning switch 28 and starting the timer 21, the microcontroller 22 receives the digital signal of the timer 21 and converts it into an electrical signal, which is transmitted to the motor 39, causing the rotating plate 37 to flip and cooperate with the baffle 36, rubber teeth 47 and rubber strip 48 to seal. After sealing is completed, the cleaning process is started. The cleaning process is as follows: water injection (water and detergent) - heating (heating the mixture) - circulating cleaning - draining - water injection - heating (heating the water) - circulating cleaning - drying. After drying, the rotating plate 37 of the sealing component 6 is reset and arranged in a straight line, thus completing the cleaning process of the fume purification equipment, and the fume purification equipment can operate normally.
