Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a dust suppression device for building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project, which involves the construction of various buildings. However, construction generates a large amount of dust that floats in the air, which workers inhale and that can harm their health. The dust also contributes to air pollution and impacts the environment of surrounding residential areas.

[0003] Patent publication number CN222969497U discloses a dust suppression device for construction engineering, including a mobile trolley, a water tank, a water pump, a support column, cantilever arms, a spray frame, and a dust monitoring sensor. The support column is erected in the middle of the mobile trolley; the dust monitoring sensor is located at the top of the support column; at least two cantilever arms are arranged at intervals along the support column; the ends of adjacent cantilever arms are perpendicularly connected to the support column in different directions; the outer ends of the cantilever arms are connected to the spray frame; vertically arranged atomizing nozzles are arranged on the outer side of the spray frame; the atomizing nozzles are connected to the water pump through water supply hoses. The dust monitoring sensor collects and transmits site environmental data in real time, and the controller controls the water pump to deliver water from the water tank to the atomizing nozzles. The atomizing nozzles form multiple spray surfaces around the mobile trolley, expanding the spray range of the dust suppression water and improving the dust suppression effect.

[0004] However, the device still has shortcomings: the device delivers water from the water tank to the atomizing nozzle to form multiple spray surfaces, but construction sites usually have a lot of dust on the ground. Under the influence of wind or external interference, the dust on the ground is usually raised and floats in the air. The raised dust is easy to adhere to the outer wall of the equipment or be inhaled by construction workers, which can easily reduce the dust reduction effect during construction and thus result in poor environmental protection effect. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a dust suppression device for construction engineering, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dust suppression device for construction engineering, comprising a base, an organic body on the top of the base, a water storage tank inside the left end of the organic body, and a circular groove inside the right end of the organic body. A water pump is fixedly installed inside the water storage tank. A diversion mechanism is fixedly installed on the top of the left end of the organic body. A spiral hose is provided between the bottom of the diversion mechanism and the top of the water pump. Two connecting mechanisms are symmetrically and rotatably installed inside the diversion mechanism via torsion springs. An L-shaped water gun is fixedly installed on the top of the connecting mechanisms. Two electric slide rails are symmetrically and fixedly installed at the top edge of the base. A pushing column is slidably installed inside the electric slide rail. A flat plate is fixedly installed through the outer wall of the pushing column. An inclined plate is fixedly installed on the top of the flat plate. A dust suppression filter plate is fixedly installed on the side of the flat plate away from the organic body. A damage prevention device for absorbing harmful gases at the construction site is provided on the back of the inclined plate. A diffusion prevention device to prevent gas spillage is provided around the damage prevention device.

[0007] According to the above technical solution, a moving mechanism is fixedly installed at the bottom corner of the base. The moving mechanism facilitates the positioning of the base by rolling friction. A handle is fixedly installed at the top right end of the base. The handle is convenient for workers to hold and push. The diversion mechanism receives and diverts the dust suppression water source delivered by the spiral hose.

[0008] According to the above technical solution, the connecting mechanism completes the reset work after movement through the elastic force of the torsion spring. The L-shaped water gun has a multi-hole design and sprays water in an atomized state. The back of the L-shaped water gun is located on the horizontal movement trajectory of the push column. The bottom of the flat plate contacts the top of the electric slide rail. The inclined plate is at an angle to the L-shaped water gun. The dust-suppressing filter plate intercepts the raised dust. The operator pushes the base by holding the handle. The base generates a rotational force through friction with the ground via the moving mechanism. The rotation of the moving end of the moving mechanism facilitates the displacement of the base and the machine body. At the same time, the water pump is started. The water pump inputs water into the diversion mechanism through the spiral hose. The diversion mechanism inputs water into the connecting mechanism. The connecting mechanism sprays the dust-suppressing water in an atomized state through the L-shaped water gun. The bottom of the L-shaped water gun sprays the atomized dust-suppressing water onto the ground. Furthermore, as the base continuously shifts, it achieves large-scale dust suppression. During the operation of the L-shaped water gun, the electric slide rail is activated, which drives the push column to move horizontally. During the horizontal movement of the push column, it contacts and pushes the L-shaped water gun. Through the transmission of force, the L-shaped water gun causes the connecting mechanism to start rotating along the inside of the diversion mechanism, that is, the L-shaped water gun moves in an arc trajectory. When the push column is reset, the connecting mechanism is reset by the spring force and drives the L-shaped water gun to reset. At the same time, the push column drives the plate to move synchronously, and the plate drives the inclined plate and the dust suppression filter plate to move synchronously. During the movement of the inclined plate, it always maintains an angled posture with the L-shaped water gun. That is, when spraying in the wind, the inclined plate expands and guides the blown atomized water source. At the same time, the dust suppression filter plate intercepts a small amount of dust on the ground during the spraying of the L-shaped water gun, preventing dust from entering the interior of the base and other components.

[0009] According to the above technical solution, the anti-damage device includes an L-shaped plate, which is fixedly installed on the right side of the flat plate near the push column. Several arc-shaped blocks are fixedly installed at equal intervals on the bottom surface of the L-shaped plate. A transmission rod is rotatably installed on the bottom of the inner wall of the circular groove of the machine body. Several activated carbon plates are fixedly installed at equal intervals on the outer wall of the transmission rod. A U-shaped plate is movably installed through the outer wall of the spiral groove of the transmission rod. The outer wall of the U-shaped plate is slidably installed inside the machine body through a spring.

[0010] According to the above technical solution, the bottom of the L-shaped plate contacts the top of the base, and a non-self-locking spiral groove is provided on the outer wall of the bottom end of the transmission rod. The activated carbon plate absorbs harmful gases drifting towards the workers through activated carbon. The bottom ends of the U-shaped plate are designed with arc surfaces, and the bottom ends of the U-shaped plate are located on the movement trajectory of the arc block. The flat plate drives the L-shaped plate to move horizontally. When the L-shaped plate drives the arc block to move horizontally, the arc block contacts the arc surface at the bottom end of the U-shaped plate. With the push of the arc block, the U-shaped plate generates an upward force. At this time, the U-shaped plate slides upward along the non-self-locking spiral groove of the transmission rod. Relying on the limiting force of the spiral groove, the transmission rod generates a rotational force and begins to rotate. The transmission rod drives the activated carbon plate to revolve. With the help of the revolve of the activated carbon plate, harmful gases such as those emitted from paint on the construction site are absorbed.

[0011] According to the above technical solution, a vertical plate is fixedly installed on the side of the U-shaped plate away from the transmission rod, and a scraper is fixedly installed on the bottom end of the vertical plate near the moving mechanism. The outer wall of the scraper is in contact with the surface of the moving end of the moving mechanism. The scraper is used to ensure the cleanliness of the surface of the moving end of the moving mechanism. After the bottom end of the U-shaped plate disengages from the arc block, it is reset by the spring force. This process is repeated, causing the U-shaped plate to drive the vertical plate to move upwards and reset. The vertical plate drives the scraper to move synchronously. When the scraper moves upwards, it disengages from the contact with the moving end of the moving mechanism. When the scraper resets, it contacts the outer wall of the moving end of the rotating moving mechanism. The indirect contact of the scraper avoids motion interference to the moving mechanism.

[0012] According to the above technical solution, the anti-diffusion device includes a vertical plate, the bottom of which is fixedly installed at the top edge of the U-shaped plate, a rotating roller is rotatably installed inside the top of the vertical plate, an elastic protective plate is fixedly installed at the top right end of the machine body, and an arc block is fixedly installed on the side of the elastic protective plate near the vertical plate at its telescopic end.

[0013] According to the above technical solution, the rotating roller reduces the wear on the top of the vertical plate through rotational friction. The elastic protective plate is telescopic and is located around the activated carbon plate. The outer wall of the arc block is located on the trajectory of the rotating roller. When the U-shaped plate moves upward, it drives the vertical plate to move synchronously. The vertical plate drives the rotating roller to move closer to the arc block and make contact. When the rotating roller contacts the arc block, friction is generated. The rotating roller rotates inside the vertical plate due to friction. As the rotating roller makes contact, it causes the arc block to generate a force. At this time, the arc block pushes the telescopic end of the elastic protective plate to retract closer to the transmission rod. When the rotating roller returns to its original position after passing the vertical plate, it releases the limit on the arc block. At this time, the elastic protective plate returns to its original position by the spring force. This process is repeated.

[0014] According to the above technical solution, the anti-diffusion device also includes a U-shaped frame. The outer wall of the U-shaped frame is slidably mounted on the surface of the activated carbon plate by a spring. The end of the U-shaped frame away from the transmission rod is located on the movement trajectory of the telescopic end of the elastic protective plate. The U-shaped frame achieves horizontal reset through elastic force. Angle plates are equidistantly and fixedly installed inside the U-shaped frame. The outer wall of the angle plates is in contact with the surface of the activated carbon plate. When the activated carbon plate revolves, it drives the U-shaped frame and the angle plates to move synchronously. During the revolution, the U-shaped frame will be resisted by the telescopic end of the elastic protective plate. At this time, the U-shaped frame drives the angle plates to scrape horizontally along the surface of the activated carbon plate, and the U-shaped frame resets through spring force. This process is repeated.

[0015] This invention provides a dust suppression device for construction engineering. It has the following beneficial effects: (1) The present invention uses a water pump, a diversion mechanism, a connecting mechanism, an L-shaped water gun, an electric slide rail, a push column, a flat plate, an inclined plate and a dust-suppressing filter plate in combination. Through the moving end of the moving mechanism, it is convenient for workers to use the L-shaped water gun to suppress dust at the construction site. At the same time, water is sprayed on the ground to prevent dust on the construction site from being constantly raised by the wind or external interference, and to prevent dust from adhering to the outer wall of the equipment or being inhaled by construction workers, thus optimizing the dust suppression and environmental protection effect. Through the outward expansion and guidance of the inclined plate, it is not necessary to frequently change the direction of travel of the base when the wind direction changes, and to a certain extent, water waste and dust suppression range are avoided. At the same time, the dust-suppressing filter plate intercepts the ground dust in time, preventing the small amount of dust stirred up when the moving mechanism moves from eroding the interior of the structural components and preventing the subsequent maintenance time of the equipment from increasing.

[0016] (2) The present invention, through the setting of the anti-damage device, uses a combination of a flat plate, an L-shaped plate, an arc-shaped block, a transmission rod, an activated carbon plate, a U-shaped plate, a vertical plate and a scraper. The revolving activated carbon plate absorbs and purifies the harmful gases that drift toward the workers, reducing the content of harmful gases absorbed by the workers during the construction stage, improving the safety of the workers during the construction stage, and reducing the content of harmful substances in the air, thus optimizing the environmental protection effect. Through the limiting of the scraper and the rotation of the moving end of the moving mechanism, the wet mud and sand on the surface of the moving end of the moving mechanism during the dust suppression process can be effectively removed, ensuring its surface cleanliness and avoiding the increase of friction between the moving mechanism and the ground due to the adhesion of mud and sand, which affects the smoothness of displacement and increases physical exertion.

[0017] (3) The present invention, through the setting of the anti-diffusion device, through the cooperation of U-shaped plate, vertical plate, rotating roller, elastic protective plate, arc block, U-shaped frame and corner plate, achieves the coverage around the activated carbon plate by the reciprocating contraction and reset of the elastic protective plate, which to a certain extent accelerates the absorption rate of harmful components drifting into the range of the activated carbon plate and reduces the overflow of harmful components when the activated carbon plate revolves; by the corner plate scraping the activated carbon plate horizontally, it effectively avoids the surface of the activated carbon plate from being affected by dirt, which affects the contact between the activated carbon inside and the harmful components, thereby reducing the purification effect on the harmful components, and further prevents the harmful components from overflowing due to insufficient absorption on the original basis.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Please see Figures 1-8 One embodiment of the present invention is as follows: a dust suppression device for construction engineering includes a base 1, an organic body 3 on the top of the base 1, a water storage tank inside the left end of the organic body 3, and a circular groove inside the right end of the organic body 3. A water pump 5 is fixedly installed inside the water storage tank of the organic body 3. A diversion mechanism 6 is fixedly installed on the top of the left end of the organic body 3. A spiral hose is provided between the bottom of the diversion mechanism 6 and the top of the water pump 5. Two connecting mechanisms 7 are symmetrically and rotatably installed inside the diversion mechanism 6 through torsion springs. An L-shaped water gun 8 is fixedly installed on the top of the connecting mechanism 7. Two electric slide rails 9 are symmetrically and fixedly installed at the top edge of the base 1. A push column 10 is slidably installed inside the electric slide rail 9. A flat plate 11 is fixedly installed through the outer wall of the push column 10. An inclined plate 12 is fixedly installed on the top of the flat plate 11. A dust suppression filter plate 13 is fixedly installed on the side of the flat plate 11 away from the organic body 3. A damage prevention device 14 for absorbing harmful gases at the construction site is provided on the back of the inclined plate 12. A diffusion prevention device 15 to prevent gas spillage is provided around the damage prevention device 14.

[0022] A moving mechanism 2 is fixedly installed at the bottom corner of the base 1. The moving mechanism 2 uses rolling friction to facilitate the positioning of the base 1. A handle 4 is fixedly installed at the top right end of the base 1. The handle 4 is convenient for the staff to hold and push. The diversion mechanism 6 receives and diverts the dust suppression water source transported by the spiral hose.

[0023] The connecting mechanism 7 completes the reset work after movement through the elastic force of the torsion spring. The L-shaped water gun 8 has a multi-hole design and sprays water in an atomized state. The back of the L-shaped water gun 8 is located on the horizontal movement trajectory of the push column 10. The bottom of the plate 11 contacts the top of the electric slide rail 9. The inclined plate 12 is at an angle to the L-shaped water gun 8. The dust filter plate 13 intercepts the dust that is raised.

[0024] The mobile end of the mobile mechanism 2 allows workers to use the L-shaped water gun 8 to suppress dust at the construction site, while simultaneously spraying water onto the ground. This prevents dust from being constantly stirred up by the wind or external forces, and avoids dust adhering to the outer wall of the equipment or being inhaled by construction workers, thus optimizing dust suppression and environmental protection. The outward expansion of the inclined plate 12 allows the base 1 to move without frequently changing its direction when the wind direction changes, and also avoids water waste and increases the dust suppression range to a certain extent. At the same time, the dust filter plate 13 intercepts ground dust in a timely manner, preventing the small amount of dust stirred up by the mobile mechanism 2 from corroding the internal structure of the components and preventing an increase in the maintenance time of subsequent equipment.

[0025] During use, the operator pushes the base 1 by holding the handle 4. The base 1 rotates due to friction with the ground via the moving mechanism 2. The rotation of the moving end of the moving mechanism 2 facilitates the displacement of the machine body 3 by the base 1. Simultaneously, the water pump 5 is activated, and water is fed into the diversion mechanism 6 through a spiral hose. The diversion mechanism 6 then feeds water into the connecting mechanism 7. The connecting mechanism 7 sprays the dust-suppressing water in an atomized manner through the L-shaped water gun 8. The bottom of the L-shaped water gun 8 sprays the atomized dust-suppressing water onto the ground, and as the base 1 continues to move, it achieves large-area dust suppression. During the operation of the L-shaped water gun 8, the electric slide rail 9 is activated, which drives the push column 10 to move horizontally. The horizontal movement of the push column 10... The L-shaped water gun 8 is pushed and propelled by the force. Through the transmission of force, the L-shaped water gun 8 causes the connecting mechanism 7 to start rotating along the inside of the diversion mechanism 6, that is, the L-shaped water gun 8 moves in an arc trajectory. When the pushing column 10 is reset, the connecting mechanism 7 is reset by the spring force and drives the L-shaped water gun 8 to reset. At the same time, the pushing column 10 drives the plate 11 to move synchronously. The plate 11 drives the inclined plate 12 and the dust filter plate 13 to move synchronously. During the movement, the inclined plate 12 is always in an angled position with the L-shaped water gun 8. That is, when spraying in the wind, the inclined plate 12 expands and guides the blown atomized water source. At the same time, the dust filter plate 13 intercepts a small amount of dust on the ground during the spraying of the L-shaped water gun 8 to prevent dust from entering the interior of the base 1 and other components.

[0026] According to the above embodiments, the moving end of the moving mechanism 2 allows workers to use the L-shaped water gun 8 to suppress dust at the construction site, while simultaneously spraying water onto the ground. This prevents dust from being constantly stirred up by the wind or external forces, and avoids dust adhering to the outer wall of the equipment or being inhaled by construction workers, thus optimizing the dust suppression and environmental protection effects. The outward expansion of the inclined plate 12 allows the base 1 to move without frequently changing its direction when the wind direction changes, and also avoids water waste and increases the dust suppression range to a certain extent. At the same time, the dust filter plate 13 intercepts ground dust in a timely manner, preventing the small amount of dust stirred up by the moving mechanism 2 from corroding the interior of the structural components and preventing an increase in the maintenance time of subsequent equipment.

[0027] Please see Figures 1-8 Based on the above embodiments, another embodiment of the present invention further includes a damage prevention device 14; The anti-damage device 14 includes an L-shaped plate 141, which is fixedly installed on the right side of the plate 11 near the push column 10. Several arc-shaped blocks 142 are fixedly installed at equal intervals on the bottom surface of the L-shaped plate 141. A transmission rod 143 is rotatably installed on the bottom of the inner wall of the circular groove of the machine body 3. Several activated carbon plates 144 are fixedly installed at equal intervals on the outer wall of the transmission rod 143. A U-shaped plate 145 is movably installed through the outer wall of the spiral groove of the transmission rod 143. The outer wall of the U-shaped plate 145 is slidably installed inside the machine body 3 through a spring.

[0028] The bottom of the L-shaped plate 141 contacts the top of the base 1. The outer wall of the bottom end of the transmission rod 143 is provided with a non-self-locking spiral groove. The activated carbon plate 144 absorbs harmful gases that drift toward the workers through activated carbon. The bottom ends of the U-shaped plate 145 are designed with arc surfaces. The bottom ends of the U-shaped plate 145 are located on the movement trajectory of the arc block 142.

[0029] A vertical plate 146 is fixedly installed on the side of the U-shaped plate 145 away from the transmission rod 143. A scraper 147 is fixedly installed on the bottom end of the vertical plate 146 near the moving mechanism 2. The outer wall of the scraper 147 is in contact with the moving end surface of the moving mechanism 2. The scraper 147 is used to ensure the cleanliness of the moving end surface of the moving mechanism 2.

[0030] The revolving activated carbon plate 144 absorbs and purifies harmful gases that drift towards the workers, reducing the amount of harmful gases absorbed by the workers during the construction phase, improving the safety of the workers during the construction phase, and at the same time reducing the content of harmful substances in the air and optimizing the environmental protection effect; through the limiting of the scraper 147 and the rotation of the moving end of the moving mechanism 2, the wet mud and sand adhering to the surface of the moving end of the moving mechanism 2 during the dust suppression process can be effectively removed, ensuring its surface cleanliness and avoiding the increase of friction between the moving mechanism 2 and the ground due to the adhesion of mud and sand, which would affect the smoothness of the displacement and increase physical exertion.

[0031] In use, the flat plate 11 drives the L-shaped plate 141 to move horizontally. When the L-shaped plate 141 drives the arc-shaped block 142 to move horizontally, the arc-shaped block 142 contacts the bottom arc surface of the U-shaped plate 145. As the arc-shaped block 142 pushes, it causes the U-shaped plate 145 to generate an upward force. At this time, the U-shaped plate 145 slides upward along the non-self-locking spiral groove of the transmission rod 143. Relying on the limiting force of the spiral groove, the transmission rod 143 generates a rotational force and begins to rotate. The transmission rod 143 drives the activated carbon plate 144 to revolve. With the help of the revolve of the activated carbon plate 144, the activated carbon plate 144 rotates. The U-shaped plate 145 absorbs harmful gases emitted from the paint on the construction site. After the bottom end of the U-shaped plate 145 disengages from the arc-shaped block 142, it returns to its original position by the spring force. This process is repeated, causing the U-shaped plate 145 to drive the vertical plate 146 to move upwards and return to its original position. The vertical plate 146 drives the scraper 147 to move synchronously. When the scraper 147 moves upwards, it disengages from the moving end of the moving mechanism 2. When the scraper 147 returns to its original position, it contacts the outer wall of the moving end of the rotating moving mechanism 2. The indirect contact of the scraper 147 avoids causing motion interference to the moving mechanism 2.

[0032] According to the above embodiments, the revolving activated carbon plate 144 absorbs and purifies harmful gases drifting towards the workers, reducing the amount of harmful gases absorbed by the workers during the construction phase, improving the safety of the workers during the construction phase, and reducing the content of harmful substances in the air, thus optimizing the environmental protection effect. Through the limiting of the scraper 147 and the rotation of the moving end of the moving mechanism 2, the wet mud and sand adhering to the surface of the moving end of the moving mechanism 2 during the dust suppression process can be effectively removed, ensuring its surface cleanliness and avoiding the increase of friction between the moving mechanism 2 and the ground due to the adhesion of mud and sand, which would affect the smoothness of displacement and increase physical exertion.

[0033] Please see Figures 1-8 In addition to the above embodiments, another embodiment of the present invention further includes an anti-diffusion device 15; The anti-diffusion device 15 includes a vertical plate 151. The bottom of the vertical plate 151 is fixedly installed at the top edge of the U-shaped plate 145. A rotating roller 152 is rotatably installed inside the top of the vertical plate 151. An elastic protective plate 153 is fixedly installed at the top right end of the machine body 3. An arc block 154 is fixedly installed on the side of the elastic protective plate 153 near the vertical plate 151 at the telescopic end.

[0034] The rotating roller 152 reduces wear on the top of the vertical plate 151 through rotational friction. The elastic protective plate 153 is telescopic and is located around the activated carbon plate 144. The outer wall of the arc block 154 is located on the movement trajectory of the rotating roller 152.

[0035] The anti-diffusion device 15 also includes a U-shaped frame 155. The outer wall of the U-shaped frame 155 is slidably mounted on the surface of the activated carbon plate 144 by a spring. The end of the U-shaped frame 155 away from the transmission rod 143 is located on the movement trajectory of the telescopic end of the elastic protective plate 153. The U-shaped frame 155 achieves horizontal reset by elastic force. Angle plates 156 are equidistantly and fixedly installed inside the U-shaped frame 155. The outer wall of the angle plates 156 is in contact with the surface of the activated carbon plate 144.

[0036] The reciprocating contraction and resetting of the elastic protective plate 153 achieves a covering around the activated carbon plate 144, which to some extent accelerates the absorption rate of harmful components drifting into the range of the activated carbon plate 144 and reduces the spillage of harmful components when the activated carbon plate 144 revolves. The horizontal scraping of the activated carbon plate 144 by the angled plate 156 effectively prevents dirt adhering to the surface of the activated carbon plate 144 from affecting the contact between the activated carbon inside and the harmful components, thereby reducing the purification effect on the harmful components. On the original basis, it further prevents the harmful components from spilling out due to insufficient absorption.

[0037] In use, when the U-shaped plate 145 moves upward, it drives the vertical plate 151 to move synchronously. The vertical plate 151 drives the rotating roller 152 to move towards and contact the arc block 154. When the rotating roller 152 contacts the arc block 154, friction is generated. The rotating roller 152 rotates inside the vertical plate 151 due to friction. As the rotating roller 152 contacts the arc block 154, it causes the arc block 154 to generate a force for movement. At this time, the arc block 154 pushes the telescopic end of the elastic protective plate 153 to retract towards the transmission rod 143. When the rotating roller 15... 2. When the vertical plate 151 is reset, the limit on the arc block 154 is released. At this time, the elastic protective plate 153 is reset by the spring force, and this process repeats. When the activated carbon plate 144 revolves, it drives the U-shaped frame 155 and the angle plate 156 to move synchronously. During the revolution, the U-shaped frame 155 will be resisted by the extension end of the elastic protective plate 153. At this time, the U-shaped frame 155 drives the angle plate 156 to scrape horizontally along the surface of the activated carbon plate 144, and the U-shaped frame 155 is reset by the spring force, and this process repeats.

[0038] According to the above embodiments, the reciprocating contraction and reset of the elastic protective plate 153 achieves the coverage of the area around the activated carbon plate 144, which to a certain extent accelerates the absorption rate of harmful components drifting into the area of ​​the activated carbon plate 144 and reduces the spillage of harmful components when the activated carbon plate 144 revolves. The horizontal scraping of the activated carbon plate 144 by the angled plate 156 effectively prevents dirt from adhering to the surface of the activated carbon plate 144, which affects the contact between the activated carbon inside and the harmful components, thereby reducing the purification effect on the harmful components. On the basis of the original, it further prevents the harmful components from spilling out due to insufficient absorption.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
