Description

Technical Field

[0001] This invention belongs to the field of chip manufacturing technology, and specifically relates to a welding device for integrated circuit chip manufacturing. Background Technology

[0002] Integrated circuit chips are electronic devices that can perform certain circuit functions. During the production and processing of integrated circuit chips, soldering equipment is needed to solder electronic components. Soldering electronic components requires solder, which generates excessive fumes. The fumes contain dust particles and harmful substances. The harmful substances contain excessive amounts of carbon monoxide, carbon dioxide, methanol, ethanol, methane, formaldehyde and other harmful components. These substances will produce a strong pungent odor after oxidation.

[0003] Existing welding equipment used in integrated circuit chip manufacturing cannot effectively handle the fumes generated during welding. Long-term inhalation of these fumes by operators can easily lead to respiratory infections and lung structural lesions. Summary of the Invention

[0004] This invention provides a welding apparatus for integrated circuit chip production, which aims to solve the problem that existing welding apparatuses for integrated circuit chip production cannot effectively handle the fumes generated during welding, and that long-term inhalation of fumes by operators can easily lead to respiratory infections and lung structural lesions.

[0005] This invention provides a welding apparatus for integrated circuit chip production, comprising a welding station. Two mounting posts are fixedly connected to the top wall of the welding station, and a clamping piece for holding an integrated circuit chip is disposed between the two mounting posts. A top block is fixedly connected to the top wall of the two mounting posts. A movable block is disposed at the bottom end of the top block. A linear actuator A is fixedly connected to the bottom wall of the movable block, and a movable block is fixedly connected to the output end of the linear actuator A. A welding component is fixedly connected to the bottom wall of the movable block. A cleaning assembly for absorbing and treating fumes is mounted on the welding station. The cleaning assembly includes an air inlet, a flexible hose, and a rigid... arranged sequentially from left to right. The assembly includes a heat pipe, a cleaning housing, and an exhaust fan. The air inlet is fitted onto the outside of the welded part, and its top end is fixedly connected to a movable block. One end of the flexible hose is connected to the inside of the air inlet, and the other end of the flexible hose is connected to the rigid heat pipe. The end of the rigid heat pipe further from the flexible hose is connected to the cleaning housing. The cleaning housing is a shell with an internal cavity, and the rigid heat pipe and the cleaning housing are installed parallel to the welding station. A porous carbon block is installed inside the cleaning housing. The exhaust fan is installed at the end of the cleaning housing further from the rigid heat pipe. The exhaust fan and the cleaning housing are detachably assembled, and the air inlet of the exhaust fan is connected to the inside of the cleaning housing.

[0006] By adopting the above technical solution, during welding, the integrated circuit chip is clamped between two clamping plates, and the workpiece is heated simultaneously. Linear driver A is activated, and the output end of linear driver A becomes longer, pulling the workpiece downward to perform welding. Since the lower opening of the air inlet is facing the weld point, the exhaust fan is activated. Under the function of the exhaust fan, the air inlet absorbs the fumes generated during welding, and the fluid mixed with fumes is introduced into the rigid conduit through the hose. The fumes are initially screened by the fluid through the sieve plate A. The fumes after initial screening enter the cleaning shell. When the fumes pass through the carbon blocks inside the cleaning shell, harmful substances adhere to the carbon blocks, thereby achieving the goal of removing harmful substances from the fumes.

[0007] Furthermore, a sieve plate A is installed in the rigid conduit, which is used to separate dust particles in the smoke.

[0008] By adopting the above technical solution, dust particles in the smoke are prevented from adhering to the surface of the carbon block, thus affecting the carbon block's ability to remove harmful substances in the smoke.

[0009] Furthermore, an annular platform is sleeved on the outside of the rigid conduit, and the annular platform and the rigid conduit are welded together. An airway A is reserved in the annular platform. The airway A is located at the top of the rigid conduit. Both the left and right ends of the airway A are connected to the inside of the rigid conduit, and the left and right interfaces of the airway A are located on the left and right sides of the sieve plate A, respectively.

[0010] The top wall of the annular platform has two vertical openings, A and B, each with a rectangular cross-section. Both openings A and B penetrate the upper and lower walls of the annular platform. They are arranged side-by-side along the transverse centerline of the rigid conduit. Opening A is located between the left interface of the sieve plate A and the airway A, and it connects to both the airway A and the inside of the rigid conduit. A movable piece A is installed within opening A, its outer surface airtightly connected to the inner wall of opening A. The movable piece A is movably installed within opening A. The tail of the variable piece A is located inside the port A, and the head of the variable piece A extends to the outside of the rigid conduit. The port B is located between the right interface of the airway A and the cleaning shell. The variable piece B is installed in the port B. The outer surface of the variable piece B is airtightly connected to the inner wall of the port B. The variable piece B is movably installed in the port B. The tail of the variable piece B is located inside the port B, and the head of the variable piece B extends to the outside of the rigid conduit. The top walls of the variable piece A and the variable piece B are fixed together with an adjacent block. The adjacent block is parallel to the rigid conduit.

[0011] The cross-sectional area of ​​the rigid conduit and the cross-sectional area of ​​airway A are both smaller than the cross-sectional areas of the variable plate A and the variable plate B. The variable plate A has a through hole A in the middle that is compatible with the rigid conduit, and the variable plate B has a through hole B in the middle that is compatible with the rigid conduit. The transverse center line of the through hole A and the transverse center line of the through hole B are collinear.

[0012] An airway B is formed on the bottom wall inside the rigid conduit. One end of the airway B is located between the moving plate A and the sieve plate A, and the other end of the airway B is connected to the tail of the opening A.

[0013] A support frame is fixedly connected to the top wall of the annular platform, and a linear actuator B is vertically mounted on the support frame. The top wall of the linear actuator B is fixedly connected to the support frame, and the output end of the linear actuator B is fixedly connected to the adjacent block.

[0014] The bottom wall of the rigid conduit is equipped with an air guide tube A, an air guide tube B, and a barrel. The barrel contains liquid, and the head of the barrel is threaded to a sealing shell. The upper interface of the air guide tube A is connected to the lower interface of the port A, and the tail of the air guide tube A extends to the bottom of the liquid. One end of the air guide tube B is connected to the top of the inside of the barrel, and the end of the air guide tube B connected to the barrel is at the top of the liquid in the barrel. The other end of the air guide tube B is connected to the inside of the rigid conduit, and the end of the air guide tube B connected to the rigid conduit is located between the moving plate B and the cleaning shell.

[0015] By adopting the above technical solution, dust particles on screen plate A can be removed through the air extraction function of the exhaust fan without interrupting the operation of the exhaust fan, effectively improving the smoke processing speed and the operating efficiency of the exhaust fan. When the number of dust particles attached to the sieve plate A is small, the smoke travels quickly through the air inlet, hose, and rigid duct during exhaust fan operation. At this time, the sieve plate A can perform a routine initial sieving of the dust particles in the smoke. Simultaneously, the output end of the linear actuator B is in the extended state, and the moving plates A and B are at their original heights. At this time, both through holes A and B are connected to the inside of the rigid duct. One of the gates on the moving plate A is in the air passage A, and the moving plate A blocks one end of the air passage B, preventing the air passage B from connecting to the through hole A. When the exhaust fan is drawing air, the smoke enters the hose and air passage A from the lower opening of the air inlet and flows towards the cleaning housing. When the smoke passes through the sieve plate A, the dust particles cannot pass through the sieve holes and remain on the wall of the sieve plate A near the hose. Meanwhile, harmful substances enter the cleaning housing with the fluid and adhere to the carbon blocks in the cleaning housing, thereby achieving the goal of removing harmful substances from the smoke.

[0016] After sieve plate A continuously operates and sieves dust particles, excessive dust particles accumulate on its wall surface. This increases the obstruction of the fluid by sieve plate A, reducing the fluid's ability to pass through it. The exhaust fan's suction speed decreases, and noise increases. Under the function of the exhaust fan, the slider moves to the right, triggering the button. This shortens the output of the linear actuator B controlled by the microcontroller, causing the moving plates A and B to move upwards to an appropriate height. The through-holes A and B in the middle of moving plate A and B move out of the rigid conduit, thus cutting off the inside of the rigid conduit at the tails of moving plates A and B. To prevent fluid from flowing from the rigid conduit to the cleaning shell, the through hole A moves upward into the airway A, allowing smoke to pass through it. The moving plate A also moves upward to connect the airway B and the through-hole A. When the exhaust fan draws air, the smoke flows with the fluid from the left port of airway A into airway A, and then from the right port of airway A into the rigid conduit. The fluid then passes through the screen plate A and flows into airway B, exiting from the lower port of the air duct A and settling in the liquid inside the tank. The settled harmful substances then flow with the fluid from the air duct B into the cleaning shell. The carbon blocks in the cleaning shell achieve the goal of adhering to and removing the harmful substances.

[0017] Smoke flows with the fluid from the left inlet of airway A into airway A, and then from the right inlet of airway A into the inside of the rigid conduit. The fluid then passes through sieve plate A and flows into airway B. During the fluid's journey from the left end to the right end of sieve plate A, dust particles accumulated on the wall of sieve plate A near the flexible tube are blown off. The dust particles blown off sieve plate A are carried by the fluid through airway B, the inside of port A, and air guide tube A, and exit from the lower end of air guide tube A, accumulating and settling at the bottom of the liquid in the tank, thus achieving the collection of dust particles.

[0018] The fluid flows from the right end of sieve plate A to the left end of sieve plate A. After a certain period of time, the linear actuator B is activated. The output end of the linear actuator B becomes longer, pulling the variable plate A and variable plate B back to their original height, so that the through hole A and through hole B are connected to the inside of the rigid conduit. This allows sieve plate A to resume the initial screening of the smoke flowing from left to right.

[0019] Furthermore, a sieve plate B is installed in the liquid inside the barrel. The outer surface of the sieve plate B is fixedly connected to the inner wall of the barrel. The end of the air guide pipe A, which is further away from the annular platform 732, is connected to the sealing shell installed at the top of the barrel and the sieve plate B. The tail of the air guide pipe A extends to the bottom of the liquid.

[0020] By adopting the above technical solution, dust particles enter the liquid with the fluid to form bubbles containing both fluid and dust particles. The setting of the sieve plate B can prevent dust particles from moving upward with the bubbles into the air guide tube B, thereby preventing dust particles from flowing into the cleaning shell and adhering to the carbon block, thus affecting the carbon block's removal efficiency of harmful substances.

[0021] Furthermore, two sliding holes are mirror-imaged on the inner wall of the rigid conduit, and the sliding holes are installed parallel to the rigid conduit. Two sliders are mirror-imaged and fixedly connected to the outer surface of the left end of the sieve plate A. The sliders and the matching sliding holes are movably connected. A button is fixedly connected in the sliding hole near airway A. The button is located on the wall surface of the sliding hole near the cleaning shell. A spiral beryllium copper wire is sleeved on the outside of the button. The two ends of the spiral beryllium copper wire are fixedly connected to the slider and the wall surface of the sliding hole near the cleaning shell, respectively.

[0022] By adopting the above technical solution, when the number of dust particles attached to sieve plate A is small, harmful substances encounter fewer obstacles when flowing through sieve plate A along with the fluid, and can pass through sieve plate A smoothly. Therefore, the force of the slider pushing the spiral beryllium copper wire towards the button is light, and due to the rebound function of the spiral beryllium copper wire itself, the slider cannot reach and press the button. After sieve plate A continues to operate and sieve dust particles, too many dust particles will accumulate on its wall surface. The obstruction of sieve plate A to the fluid increases, and the fluid's ability to pass through sieve plate A deteriorates. Under the suction function of the exhaust fan, the force of the slider pushing the spiral beryllium copper wire towards the button increases, and the slider moves towards the button. The device moves and touches the button, which transmits an electrical signal to the microcontroller. The microcontroller then shortens the output of the linear actuator B, causing the moving plates A and B to move upwards. The output of the linear actuator B remains shortened for a period of time, using the fluid flowing from the right end to the left end of the sieve plate A to remove dust particles adhering to it. After the dust particles are removed, the microcontroller lengthens the output of the linear actuator B, causing the moving plates A and B to move downwards, allowing the through holes A and B to connect with the inside of the rigid conduit. This allows the sieve plate A to resume its initial screening of the smoke flowing from left to right. The above technical solution can automatically identify the amount of dust particles accumulated in the side wall of screen plate A based on the ventilation capacity of screen plate A. When the amount of dust particles accumulated in screen plate A is large, the fluid that originally flowed from the left end to the right end of screen plate A will automatically change to flow from the right end to the left end of screen plate A, thereby blowing off the dust particles left on screen plate A and completing the cleaning of screen plate A. This avoids the trouble of the operator having to constantly observe the accumulation of dust particles on screen plate A.

[0023] Furthermore, the sieve plate A has a frustum-shaped structure with the left end larger than the right end, the left end of the sieve plate A is close to the air inlet, and the slider is fixedly connected to the left end of the sieve plate A.

[0024] By adopting the above technical solution, the contact surface of sieve plate A with the smoke is increased, thereby improving the sieving speed.

[0025] Furthermore, a sieve plate C is installed at the left interface of the airway A. The rigid conduit located at the left interface of the airway A is a narrow tube. The inner diameter of the rigid conduit at another location is larger than the inner diameter of the narrow tube. The left interface of the airway A is connected to the inside of the narrow tube. A through hole C is opened at the upper part of the variable plate A. The through hole C passes through the variable plate A. When the output end of the linear actuator B becomes longer, the through hole C descends into the airway A. A gate is installed in the through hole C. When the fluid passes through the gate, it can only flow from the right interface of the airway A to the left interface of the airway A.

[0026] By adopting the above technical solution, during the period when smoke flows into airway A from the left port of airway A, the smoke passes upward through the sieve plate C, and the dust particles in the smoke are screened and attached to the sieve plate C. When the sieve plate A resumes the situation of screening the smoke passing from left to right, the flow velocity of the fluid increases as the smoke passes through the narrow tube, making the air pressure at the narrow tube lower than the air pressure at other locations in the rigid duct, thereby forming a pressure difference. The pressure difference causes part of the fluid to enter airway A from the right port of airway A, and then passes downward through the left port of airway A through the gate to the narrow tube. The fluid passes through the sieve plate C from top to bottom, achieving the goal of blowing away the dust particles on the sieve plate C.

[0027] Furthermore, a rotating column is vertically installed at the right interface of the airway A. The head of the rotating column is located in the airway A, and the tail of the rotating column extends into the inside of the rigid conduit. A strip-shaped positioning strip is fixedly connected to the inner wall of the right interface of the airway A. The head of the rotating column and the positioning strip are rotatably connected. A fan blade is installed on the outer wall of the rotating column located in the airway A, and a silicone strip is fixedly connected to the tail of the rotating column.

[0028] By adopting the above technical solution, when the output end of the linear actuator B is shortened, the smoke flows from airway A into airway B along with the fluid. When it passes through the rotating column, the generated wind force drives the fan blades to rotate, thereby causing the rotating column and the silicone strip to rotate. When the silicone strip rotates, the end of the silicone strip changes from a vertical shape to an extended shape. The end of the silicone strip hits the side wall of the screen plate A, thereby increasing the speed at which dust particles fall off the screen plate A. In addition, the fluid passes from the right end of the screen plate A to the left end of the screen plate A, which helps to blow away the dust particles accumulated on the screen plate A.

[0029] Furthermore, a ventilated inner shell is movably installed inside the cleaning outer shell, the carbon block is placed inside the ventilated inner shell, and a sensor is installed inside the cleaning outer shell near the exhaust fan.

[0030] By adopting the above technical solution, the carbon block can be replaced by changing the ventilation inner shell inside the clean outer shell. At the same time, by installing a sensor, the old carbon block can be replaced in a timely manner through the monitoring of the sensor.

[0031] The beneficial effects of this invention are as follows:

[0032] 1. In the process of soldering integrated circuit chips, the present invention draws the fumes generated during soldering into a rigid conduit through the air inlet and eventually into the clean housing. Harmful substances adhere to the carbon block, thus achieving better treatment of the fumes. By removing harmful substances, the operating conditions of the operator are improved, and the problem of respiratory tract infection and lung lesions caused by long-term inhalation of fumes is avoided.

[0033] 2. Through the installation of sieve plate A, the present invention achieves the goal of initial screening of dust particles when smoke passes through sieve plate A. The dust particles are retained on sieve plate A, preventing them from flowing into the cleaning shell. This prevents dust particles from adhering to the surface of the carbon block and affecting the removal of harmful substances from the smoke by the carbon block, thereby improving the efficiency of the carbon block in removing harmful substances.

[0034] 3. This invention, through the installation of movable plate A, movable plate B, and through-hole A and through-hole B, utilizes the coordinated action of movable plate A, movable plate B, through-hole A, and through-hole B to automatically adjust the fluid flow from the left end to the right end of sieve plate A to the right end to the left end of sieve plate A. This achieves the removal of dust particles on sieve plate A, improves the screening efficiency of sieve plate A, reduces the replacement frequency of sieve plate A, and increases the duration for which a single sieve plate A can perform screening functions, thereby reducing production costs. Furthermore, the treatment of smoke does not need to be interrupted when removing dust particles from sieve plate A.

[0035] 4. The present invention, through the installation of the barrel, uses liquid to settle the dust particles blown off the sieve plate A, thereby preventing the dust particles after the initial screening from flying into the operating room and preventing the operator from inhaling them.

[0036] 5. This invention, through the installation of a sliding hole, a spiral beryllium copper wire, and a button that works in conjunction with the linear actuator B, automatically identifies the amount of dust particles accumulated in the side wall of the sieve plate A based on the ventilation capacity of the sieve plate A. When the amount of dust particles accumulated in the sieve plate A is large, the fluid, which originally flowed from the left end to the right end of the sieve plate A, automatically changes to flow from the right end to the left end of the sieve plate A, thereby blowing off the dust particles remaining on the sieve plate A and completing the cleaning of the sieve plate A.

[0037] 6. With the installation of the rotating column, fan blades and silicone strip, when the fluid flows into the rigid duct from the right interface of the air passage A, the wind force drives the fan blades, rotating column and silicone strip to rotate. The end of the silicone strip rotates and unfolds and hits the screen plate A. In addition, the fluid passes from the right end of the screen plate A to the left end of the screen plate A, forcing dust particles to fall off the screen plate A, thereby improving the ventilation capacity of the screen plate A, thereby improving the exhaust fan's smoke extraction speed and the adhesion efficiency of carbon blocks.

A microcontroller that controls the operation of the linear driver B7341 is mounted on the linear driver B7341. The microcontroller is electrically connected to the button 739.

[0056] A gas guide pipe A735 and a gas guide pipe B736 are installed on the bottom wall of the rigid conduit 73, and a barrel 737 is installed. The barrel 737 is installed vertically, and a support leg is fixedly connected to the bottom wall of the barrel 737. The bottom end of the support leg is fixedly connected to the top wall of the welding station 1. Liquid 7371 is contained in the barrel 737, and a dry chamber is reserved in the upper part of the barrel 737. The head of the barrel 737 is threaded to a sealing shell. The bottom end of the barrel 737 has a frustum structure. A valve 2 for releasing liquid 7371 from the barrel 737 is installed at the tail of the barrel 737. The upper interface of the gas guide pipe A735 matches the lower interface of the port A7323, and the upper interface of the gas guide pipe A735 is connected to the lower interface of the port A7323. A sieve plate B7372 is installed in the liquid 7371 inside the barrel 737. The sieve plate B7372 is evenly spaced. Several sieve holes are reserved. The outer surface of the sieve plate B7372 is fixedly connected to the inner wall of the barrel 737. The end of the air guide tube A735 further away from the annular platform 732 is connected to the sealing shell installed at the top of the barrel 737 and the sieve plate B7372. The tail of the air guide tube A735 extends to the bottom of the liquid 7371. The contact surfaces of the air guide tube A735, the sealing shell of the barrel 737, and the sieve plate B7372 are tightly connected. One end of the air guide tube B736 is connected to the top of the inside of the barrel 737. The end of the air guide tube B736 connected to the barrel 737 is at the top of the liquid 7371 in the barrel 737. The other end of the air guide tube B736 is connected to the inside of the rigid conduit 73. The end of the air guide tube B736 connected to the rigid conduit 73 is between the variable plate B7327 and the cleaning shell 74.

[0057] A sieve plate C76 is installed at the left interface of airway A7322. The sieve plate C76 has several pre-drilled holes at equal intervals. The sieve plate C76 is used to separate dust particles in the smoke. The outer surface of the sieve plate C76 is fixedly connected to the inner wall of airway A7322. The rigid conduit 73 located at the left interface of airway A7322 is a narrow tube 731. The inner diameter of the rigid conduit 73 at another location is larger than the inner diameter of the narrow tube 731. The left interface of airway A7322 and... The inside of the narrow tube 731 is connected, and a through hole C77 is opened on the upper part of the variable plate A7324. The through hole C77 passes through the variable plate A7324. When the output end of the linear actuator B7341 becomes longer, the through hole C77 descends into the air passage A7322. A gate 771 is installed in the through hole C77. The gate 771 can only allow the fluid to flow to one side. When the fluid passes through the gate 771, it can only flow from the right port of the air passage A7322 to the left port of the air passage A7322.

[0058] The right interface of airway A7322 is vertically opened, and a rotating column 781 is vertically installed at the right interface of airway A7322. The head of the rotating column 781 is located in airway A7322, and the tail of the rotating column 781 extends into the inside of the rigid conduit 73. A strip-shaped positioning strip 782 is fixed to the inner wall of the right interface of airway A7322. An installation hole is opened in the middle of the positioning strip 782. The vertical center line of the installation hole is collinear with the vertical center line of the right interface of airway A7322. A copper sleeve is installed in the installation hole. The head of the rotating column 781 passes through the copper sleeve and the positioning strip 782. A fan blade 783 is installed on the outer wall of the rotating column 781 located in the air passage A7322. A silicone strip 784 is fixedly connected to the tail of the rotating column 781. When the rotating column 781 stops rotating, the end of the silicone strip 784 falls to a vertical position. When the rotating column 781 rotates, it drives the silicone strip 784 to rotate around the vertical center line of the rotating column 781. Due to the outward force generated during rotation, the end of the silicone strip 784 rises and extends, and the end of the silicone strip 784 can contact the right end face of the sieve plate A733.

[0059] The specific implementation method is as follows: During use, the integrated circuit chip is clamped between two clamping plates 3, and the welding part 6 is heated at the same time. The linear driver A is started, and the output end of the linear driver A becomes longer and pulls the welding part 6 to move down to perform welding. During welding, the lower opening of the air inlet 71 faces the welding point, and the exhaust fan 75 is started. The air inlet 71 absorbs the smoke generated by welding and introduces the smoke into the rigid conduit 73 through the hose 72. The fluid mixed with smoke is initially screened through the sieve plate A733. The smoke after initial screening enters the cleaning shell 74. When the smoke passes through the carbon block inside the cleaning shell 74 with the fluid, harmful substances adhere to the carbon block, thereby achieving the goal of removing harmful substances from the smoke.

[0060] When the number of dust particles attached to the sieve plate A733 is small, during the exhaust fan 75's suction, the smoke in the air inlet 71, hose 72, and rigid conduit 73 travels at a fast speed. At this time, the sieve plate A733 can perform routine initial screening of the dust particles in the smoke. Harmful substances encounter fewer obstacles when passing through the sieve plate A733 along with the fluid and can pass through the sieve plate A733 smoothly. As a result, the force of the slider 7331 pushing the spiral beryllium copper wire 7381 towards the button 739 is light. Due to the rebound function of the spiral beryllium copper wire 7381 itself, the slider 7331 cannot reach and press the button 739. At this time, the output end of the linear actuator B7341 is in the extended state and remains unchanged, while the variable plate A7324 and variable plate B7327 are in the original state. The height is such that through-holes A7325 and B7328 are connected to the inside of the rigid conduit 73. The stop valve 771 on the variable plate A7324 is located in the air passage A7322. At the same time, the variable plate A7324 blocks one end of the air passage B7329, preventing the air passage B7329 from connecting with the port A7323. When the exhaust fan 75 draws air, the smoke enters the hose 72 and the air passage A7322 from the lower opening of the air inlet 71 and flows towards the cleaning housing 74. When the smoke passes through the sieve plate A733, dust particles cannot pass through the sieve holes. The dust particles are retained at the wall of the sieve plate A733 near the hose 72, achieving the goal of the sieve plate A733 to remove dust particles from the smoke. Harmful substances enter the cleaning housing 74 with the fluid.

[0061] After the sieve plate A733 continuously sieves dust particles, too many dust particles will accumulate on its wall surface. The sieve plate A733 will increase its obstruction to the fluid, and the fluid's ability to pass through the sieve plate A733 will decrease. Under the suction function of the exhaust fan 75, the slider 7331 will push the spiral beryllium copper wire 7381 towards the button 739 with increased force. The slider 7331 will move towards the button 739 and touch the button 739 to press it. The button 739 will transmit an electrical signal to the microcontroller. As a result, the output end of the linear driver B7341 controlled by the microcontroller will shorten, thereby pulling the moving plate A7324 and moving plate B7327 upward.

[0062] Reference Figure 4When the variable plates A7324 and B7327 move upwards, the through holes A7325 in the middle of variable plate A7324 and B7328 in the middle of variable plate B7327 move out from inside the rigid conduit 73. This causes the tails of variable plates A7324 and B7327 to cut off the inside of the rigid conduit 73, preventing fluid from flowing from inside the rigid conduit 73 to the cleaning housing 74. At this time, through hole A7325 moves upwards into the air passage A7322, allowing smoke to pass through the air passage A7322. The upward movement of variable plate A7324 connects air passage B7329 and opening A7323. When the exhaust fan 75 draws air, smoke flows with the fluid from the left interface of air passage A7322 into air passage A7322, and from the right interface of air passage A7322... The fluid flows into the rigid conduit 73, then passes through the screen plate A733 and flows into the air passage B7329. During the flow of the fluid from the right end of the screen plate A733 to the left end of the screen plate A733, the dust particles accumulated on the wall of the screen plate A733 near the hose 72 are blown off. The dust particles blown off the screen plate A733 follow the flowing fluid through the air passage B7329, the opening A7323 and the air guide tube A735 in sequence, and come out from the lower end of the air guide tube A735 and accumulate and settle at the bottom of the liquid 7371 in the tank 737, thereby achieving the goal of collecting dust particles. The harmful substances after sedimentation flow with the fluid from the air guide tube B736 into the cleaning shell 74. The harmful substances adhere to the carbon block, thereby achieving the goal of removing harmful substances from the smoke.

[0063] When slider 7331 touches and button 739 is pressed, the output of linear actuator B7341 controlled by the microcontroller shortens and remains unchanged, causing the moving plates A7324 and B7327 to move upward. This allows the fluid flowing from the right end to the left end of sieve plate A733 to remove dust particles attached to sieve plate A733. After the dust particles on sieve plate A733 are removed, the output of linear actuator B7341 controlled by the microcontroller lengthens, pulling moving plates A7324 and B7327 downward, allowing through holes A7325 and B7328 to communicate with the inside of rigid conduit 73. This allows sieve plate A733 to resume its initial screening of smoke flowing from left to right.

[0064] During the flow of smoke into airway A7322 from the left port, the smoke passes upward through the sieve plate C76, and dust particles in the smoke are sieved and adhere to the sieve plate C76. When the sieve plate A733 resumes sieving the smoke flowing from left to right, the flow velocity of the fluid increases as the smoke passes through the narrow tube 731, making the air pressure at the narrow tube 731 lower than the air pressure at other locations of the rigid conduit 73, thus creating a pressure difference. The pressure difference causes some fluid to enter airway A7322 from the right port and pass downward through the valve 771 from the left port of airway A7322 into the narrow tube 731. The fluid passes downward through the sieve plate C76, blowing away the dust particles on the sieve plate C76.

[0065] When the output end of the linear actuator B7341 is shortened, the smoke flows into the rigid duct 73 from the air passage A7322 along with the fluid. When it passes through the rotating column 781, the generated wind force drives the fan blade 783 to rotate, thereby causing the rotating column 781 and the silicone strip 784 to rotate. When the silicone strip 784 rotates, the end of the silicone strip 784 changes from a vertical state to an extended state. The end of the silicone strip 784 strikes the side wall of the sieve plate A733, thereby increasing the speed at which dust particles fall off the sieve plate A733. In addition, the fluid passes from the right end of the sieve plate A733 to the left end of the sieve plate A733, which helps to blow away the dust particles accumulated on the sieve plate A733.
