Description

Technical Field

[0001] This invention relates to the field of fan technology, and more specifically, to an integrated dust removal fan. Background Technology

[0002] Fans generate centrifugal force or axial thrust through the rotation of impellers, enabling gas to gain kinetic or pressure energy for transport or compression. They are mainly used in gas transport, ventilation, pressurization and other applications.

[0003] To improve people's quality of life, fans are often used to ventilate indoor spaces. This ensures effective air circulation, reduces indoor temperature, and removes odors and moisture. However, after a period of use, dust accumulates on components such as the fan impeller, increasing the fan's energy consumption and affecting its ventilation efficiency.

[0004] To address the aforementioned issues, some solutions have been proposed in existing technologies. For example, Chinese invention application CN120007611A discloses a roof ventilator with a dust removal and self-cleaning function. When cleaning is required, the inlet dust collector activates, blowing air towards the main fan, accelerating airflow and stirring up dust from components such as the motor, impeller, casing, and outlet guide. The dust is then discharged through the outlet guide with the airflow, reducing the frequency of manual cleaning. However, in actual use, when dust is discharged with the air, it spreads around the fan. During ventilation, a large amount of dust flows back towards the fan with the airflow and adheres to the impeller, severely affecting ventilation efficiency. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide an integrated dust removal fan that can improve the ventilation effect.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] An integrated dust removal fan includes a frame, on which a fan body is fixedly installed, and on which a dust removal hood is fixedly installed. The dust removal hood has evenly spaced guide grooves and a dust removal component.

[0008] The dust removal assembly includes a rotating rod rotatably mounted on the side wall of a dust removal hood, a connecting rod rotatably mounted on the rotating rod, an impeller fixedly mounted on the connecting rod, an annular plate slidably mounted on the inner wall of the dust removal hood, a filter screen slidably fitted with the rotating rod fixedly mounted on the annular plate, an elastic telescopic tube fixedly mounted on the rotating rod, an installation ring fixedly mounted on the elastic telescopic tube, a cleaning rod fixedly mounted on the installation ring, and a transmission assembly that cooperates with the impeller on the rotating rod.

[0009] Furthermore, the transmission assembly includes a slider slidably mounted inside a rotating rod, a connecting rope fixedly mounted on the slider, and the end of the connecting rope away from the slider passes through the rotating rod and is fixedly wound around the connecting rod. The rotating rod is provided with a locking assembly for locking the slider. An installation frame is fixedly mounted on the inner wall of the dust collector hood. A first spring is installed between the installation frame and the annular plate. A push rod that cooperates with the filter screen is fixedly mounted on the slider.

[0010] Furthermore, the locking assembly includes a mounting rod rotatably mounted on a rotating rod, a spring being installed between the mounting rod and the rotating rod, a linkage rod being fixedly mounted on the mounting rod, a locking rod being fixedly mounted on the linkage rod, and a fixing groove adapted to the locking rod 404 being provided on the slider.

[0011] Furthermore, a collection box is fixedly installed on the dust removal hood, and a collection groove communicating with the collection box is opened on the dust removal hood. A sealing plate is rotatably installed on the collection groove, and a torque spring is installed between the rotating end of the sealing plate and the dust removal hood. A first magnet is embedded in the sealing plate, and a second magnet that attracts the first magnet is embedded in the annular plate.

[0012] Furthermore, a guide telescopic tube is installed between the annular plate and the mounting frame. A cavity is provided on the mounting frame, a dust collection trough is provided on the dust collection hood, a dust collection hole communicating with the collection trough is provided on the dust collection trough, and a drain valve with its output end extending into the dust collection trough is inserted into the cavity.

[0013] Furthermore, a filter plate is detachably installed inside the collection box, and the collection box is filled with dust removal liquid. An inlet valve with its input end connected to the collection box is inserted into the mounting frame, and a first one-way valve with its output end connected to the cavity is inserted into the mounting frame.

[0014] Furthermore, an annular elastic membrane is fixedly installed inside the cavity.

[0015] Furthermore, the bottom wall of the collection box is sloped, and a second one-way valve with its output end pointing downwards is fixedly installed on the bottom wall of the collection box.

[0016] Furthermore, an arc-shaped plate is fixedly installed on the annular plate.

[0017] Furthermore, the end of the locking rod away from the linkage rod is tapered, and the end of the locking rod away from the linkage rod has a smooth mirror surface.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) This solution uses dust removal components in conjunction with the fan body. When the airflow passes through the filter, the dust can be blocked directly without the need for additional independent dust removal equipment. This allows ventilation and dust removal to be carried out simultaneously, avoiding dust accumulation that affects the ventilation effect. At the same time, when the permeability of the filter changes with the accumulation of dust, the cleaning mechanism can be automatically triggered without manual intervention, ensuring smooth ventilation and improving the ventilation effect.

[0019] (2) By setting a locking component, the transmission component can lock the slider when the impeller is perpendicular to the airflow during the cleaning process through the cooperation of the locking rod and the fixing groove, ensuring that the impeller stably drives the cleaning rod to rotate and guarantee the cleaning effect. After the filter screen is cleaned, the first spring drives the filter screen to reset and triggers the locking release. The impeller automatically resets to a state parallel to the airflow, avoiding the cleaning rod from rotating and rubbing against the filter screen for a long time, reducing the wear of the filter screen and the cleaning rod, extending the service life of both, and avoiding friction to generate abnormal noise, further improving the ventilation effect and enhancing the quietness of the device operation.

[0020] (3) This solution can achieve automated dust suppression by setting up a collection box, which contains a filter plate and liquid. Combined with components such as a cavity, elastic membrane, and drain valve, the solution can achieve automated dust suppression. During the movement of the filter screen, the liquid in the collection box is extracted by pressure change and then sprayed into the collection box through the dust suppression hole to moisten and suppress the collected dust, further preventing secondary dust. The moistened dust adheres to the filter plate. When the filter plate is disassembled for cleaning, the dust can be prevented from flying and being inhaled by personnel, thereby improving the ventilation effect and protecting the health of the users.

[0023] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1 to 7 An integrated dust removal fan includes a frame 101, on which a fan body 102 is fixedly installed. A dust removal hood 103 is fixedly installed on the fan body 102. The dust removal hood 103 is provided with evenly spaced guide grooves 104 and a dust removal component 2. The dust removal assembly 2 includes a rotating rod 201 rotatably mounted on the side wall of the dust removal hood 103, a connecting rod 202 rotatably mounted on the rotating rod 201, an impeller 203 fixedly mounted on the connecting rod 202, an annular plate 204 slidably mounted on the inner wall of the dust removal hood 103, a filter screen 205 slidably cooperating with the rotating rod 201 fixedly mounted on the annular plate 204, an elastic telescopic tube 206 fixedly mounted on the rotating rod 201, an installation ring 207 fixedly mounted on the elastic telescopic tube 206, a cleaning rod 208 fixedly mounted on the installation ring 207, and a transmission assembly 3 cooperating with the impeller 203 on the rotating rod 201.

[0025] The transmission assembly 3 includes a slider 301 slidably mounted inside the rotating rod 201. A connecting rope 302 is fixedly mounted on the slider 301, and one end of the connecting rope 302 away from the slider 301 passes through the rotating rod 201 and is fixedly wrapped around the connecting rod 202. The rotating rod 201 is provided with a locking assembly 4 for locking the slider 301. An installation frame 303 is fixedly mounted on the inner wall of the dust collector 103. A first spring 304 is installed between the installation frame 303 and the annular plate 204. A push rod 305 that cooperates with the filter screen 205 is fixedly mounted on the slider 301.

[0026] The locking assembly 4 includes a mounting rod 401 rotatably mounted on a rotating rod 201. A spring 402 is mounted between the mounting rod 401 and the rotating rod 201. A linkage rod 403 is fixedly mounted on the mounting rod 401. A locking rod 404 is fixedly mounted on the linkage rod 403. A fixing groove 405 adapted to the locking rod 404 is provided on the slider 301.

[0027] Initially, the impeller 203 is parallel to the airflow direction. During operation, the fan body 102 drives the airflow through the guide channel 104 of the dust collector hood 103, then the airflow passes through the filter screen 205 into the fan body 102, and finally into the room. As the airflow passes through the filter screen 205, the filter screen 205 blocks dust in the airflow. As dust accumulates on the surface of the filter screen 205, its permeability gradually decreases. At this point, under the suction of the fan body 102, the filter screen 205 moves towards the fan body 102. During this movement, the elastic telescopic tube 206 extends and, through the mounting ring 207, drives the cleaning rod 208 to remain in contact with the surface of the filter screen 205. When the dust on the surface of the filter screen 205 reaches a level requiring cleaning, the filter screen 205 drives the connecting rod 202 to rotate via the transmission assembly 3. During the rotation of the connecting rod 202, the impeller 203 is driven to rotate, making the impeller 203 perpendicular to the direction of airflow. As the airflow passes through the impeller 203, it impacts the impeller 203 and causes it to rotate. During the rotation of the impeller 203, the connecting rod 202 drives the rotating rod 201 to rotate. During the rotation of the rotating rod 201, it drives the cleaning rod 208 to rotate along the surface of the filter screen 205 via the elastic telescopic tube 206 and the mounting ring 207. During the rotation of the cleaning rod 208, the dust on the surface of the filter screen 205 is moved towards the annular plate 204, thus preventing dust from clogging the filter screen 205 and affecting the ventilation effect, thereby improving the ventilation efficiency.

[0028] As the filter screen 205 moves toward the fan body 102, it gradually contacts the push rod 305 and applies a pushing force to it. At this time, the first spring 304 is compressed and tends to return to its original position. Then, under the action of the pushing force, the push rod 305 drives the slider 301 to move. During the movement of the slider 301, the connecting rope 302 is tightened, and the connecting rope 302 drives the connecting rod 202 to rotate against the resistance of the torsion spring, thereby driving the impeller 203 to rotate. When the impeller 203 is perpendicular to the airflow, the slider 301 reaches its maximum displacement, and at this time, the locking rod 404 contacts the fixing groove 405. Then, the spring 402 drives the mounting rod 401 to rotate. During the rotation of the mounting rod 401, the linkage rod 403 drives the locking rod 404 to insert into the fixing groove 405, thereby locking the slider 301, which in turn locks the angle of the impeller 203. This ensures that the impeller 203 can drive the cleaning rod 208 to thoroughly clean the surface of the filter screen 205, further improving the ventilation effect.

[0029] As the dust on the surface of filter screen 205 decreases, its permeability gradually increases. At this time, the first spring 304 gradually extends and, through the annular plate 204, drives filter screen 205 to reset. During the reset process, filter screen 205 gradually disengages from push rod 305. Because slider 301 is fixed by locking rod 404, impeller 203 cannot rotate axially along connecting rod 202. During the movement of filter screen 205, it drives mounting ring 207 to compress elastic telescopic tube 206, and during this process, cleaning rod 208 remains in contact with the surface of filter screen 205. Then, during the movement of filter screen 205, it gradually contacts the end of linkage rod 403 away from locking rod 404. When the cleaning of filter screen 205 is complete, the first spring 304 drives filter screen 205 to reset. During the reset, filter screen 205 pushes the end of linkage rod 403 away from locking rod 404, and then linkage rod 403 drives mounting rod 401 to rotate, at which point spring 402 begins to store power. Simultaneously, as the linkage rod 403 rotates, it causes the locking rod 404 to disengage from the fixing groove 405, at which point the fixing effect of the slider 301 is released. Then, as the airflow impacts the impeller 203, the airflow will cause the impeller 203 to rotate around the connecting rod 202, making the impeller 203 parallel to the airflow. During the rotation of the connecting rod 202 driven by the impeller 203, By using the connecting rope 302 to reset the slider 301, the impeller 203 is prevented from driving the cleaning rod 208 to rotate for a long time, which would cause wear between the filter screen 205 and the cleaning rod 208, affecting the permeability of the filter screen 205 and causing abnormal noise, thus further improving the ventilation effect.

[0030] This invention cleverly utilizes fluid dynamics principles to balance ventilation efficiency and cleaning power by changing the windward angle of the impeller 203. When the equipment is ventilating normally, the impeller 203 is parallel to the airflow direction, at which point the impeller's windward area is minimized. According to the wind resistance formula L, where The drag coefficient, Let V be the air density, v be the wind speed, and L be the lever arm. It can be seen that the airflow resistance to the impeller is minimal at this point, having almost no impact on the fan's ventilation efficiency. When cleaning is required, the impeller 203 rotates to be perpendicular to the airflow, at which point the frontal area reaches its maximum. The airflow impacts the impeller, generating the maximum driving torque M, which enables the rotating rod 201 to obtain sufficient torque to drive the cleaning rod 208 to scrape off the dust with strong adhesion on the surface of the filter screen 205, achieving an adaptive switching effect of "low flow resistance under normal conditions and high torque during cleaning".

[0031] like Figure 2 , Figure 3 , Figure 7 As shown, a collection box 501 is fixedly installed on the dust removal hood 103. A collection groove communicating with the collection box 501 is opened on the dust removal hood 103. A sealing plate 502 is rotatably installed on the collection groove. A torque spring 505 is installed between the rotating end of the sealing plate 502 and the dust removal hood 103. A first magnet 503 is embedded in the sealing plate 502. A second magnet 504 that attracts the first magnet 503 is embedded in the annular plate 204.

[0032] A guide telescopic tube 601 is installed between the annular plate 204 and the mounting frame 303. A cavity 602 is provided on the mounting frame 303. A dust collection hood 103 is provided with a dust collection groove 603. A dust collection hole communicating with the collection groove is provided on the dust collection groove 603. A drain valve 604 with its output end extending into the dust collection groove 603 is inserted into the cavity 602.

[0033] A filter plate 605 is detachably installed inside the collection box 501, and the collection box 501 is filled with dust removal liquid. An inlet valve 606 with its input end connected to the collection box 501 is inserted into the mounting frame 303, and a first one-way valve 607 with its output end connected to the cavity 602 is inserted into the mounting frame 303.

[0034] An annular elastic membrane 608 is fixedly installed inside the cavity 602.

[0035] By adopting the above technical solution, during the process of the filter screen 205 moving towards the fan body 102, the annular plate 204 drives the second magnet 504 to move away from the first magnet 503. At this time, the magnetic force between the first magnet 503 and the second magnet 504 decreases. When the magnetic force on the sealing plate 502 is less than the elastic force of the torque spring 505, the torque spring 505 extends and drives the sealing plate 502 to rotate. At this time, the collection box 501 is connected to the dust removal hood 103 through the collection groove. Then, during the rotation of the cleaning rod 208, the cleaning rod 208 drives the dust on the surface of the filter screen 205 to rotate. Under the action of centrifugal force, the dust will enter the collection box 501 along the collection groove, thereby preventing the dust from adhering to the surface of the filter screen 205 again and further improving the ventilation effect.

[0036] During the process of the first spring 304 extending and driving the filter screen 205 to move, the filter screen 205 stretches the guide telescopic tube 601 through the annular plate 204. The guide telescopic tube 601 is designed to prevent the filter screen 205 from rotating and affecting the cleaning effect. At this time, the pressure in the space between the outer wall of the guide telescopic tube 601 and the dust removal hood 103 decreases. Then, under the action of pressure, the space between the outer wall of the guide telescopic tube 601 and the dust removal hood 103 draws dust removal liquid from the collection box 501 through the liquid inlet valve 606. When the filter screen 205 drives the annular plate 204 to squeeze the first spring 304, the dust removal liquid is squeezed and flows into the cavity 602 through the first one-way valve 607, increasing the pressure in the cavity 602. Under pressure, the dust removal liquid flows into the dust settling tank 603 through the drain valve 604 and is sprayed into the collection box 501 through the dust settling holes on the dust settling tank 603. This wets and settles the dust in the collection box 501, preventing dust from being stirred up and avoiding secondary dust from re-adhering to the surface of the filter screen 205, which would affect the ventilation effect. The sprayed water also allows the dust to adhere to the surface of the filter plate 605. When the collection box 501 needs to be cleaned, the user can remove the filter plate 605. Since the dust is wetted by the dust removal liquid and adheres to the surface of the filter plate 605, it prevents secondary dust from being stirred up and inhaled by the user. This improves the ventilation effect and effectively avoids secondary dust from harming the health of the user.

[0037] The diameter ratio of the first one-way valve 607 to the drain valve 604 is 3:1, so the inflow of dust removal liquid into the cavity 602 is greater than the outflow. By setting the elastic membrane 608, it can be ensured that the dust removal liquid flows normally into the cavity 602. After the dust removal liquid flows into the cavity 602, the elastic membrane 608 gradually expands and then gradually contracts, driving the dust removal liquid to flow into the dust settling tank 603 through the drain valve 604. The setting of the diameter ratio of the first one-way valve 607 to the drain valve 604 is 3:1, which allows the dust removal liquid to be sprayed into the collection box 501 through the dust settling hole at the same time as the cleaning rod 208 drives the dust into the collection box 501, moistening and settling the dust, further improving the dust collection effect.

[0038] During the movement of the annular plate 204 and the filter screen 205 driven by the first spring 304, the annular plate 204 drives the second magnet 504 to gradually approach the first magnet 503. When the magnetic force on the sealing plate 502 is greater than the elastic force of the torque spring 505, the second magnet 504 drives the sealing plate 502 to seal the collection groove through the first magnet 503, thereby preventing dust from adhering to the surface of the filter screen 205 again and further improving the ventilation effect.

[0039] like Figure 2 As shown, the bottom wall of the collection box 501 is inclined, and a second one-way valve 701 with the output end facing downward is fixedly installed on the bottom wall of the collection box 501.

[0040] By adopting the above technical solution, in order to avoid the dust removal liquid in the collection box 501 from producing an odor after long-term use and affecting the comfort of the user, the user can periodically open the second one-way valve 701. At this time, the dust removal liquid in the collection box 501 flows along the inclined surface of the bottom wall of the collection box 501 to the second one-way valve 701 and is discharged from the collection box 501 through the second one-way valve 701.

[0041] like Figure 3 , Figure 5 As shown, an arc-shaped plate 702 is fixedly installed on the annular plate 204.

[0042] The locking rod 404 is tapered at the end away from the linkage rod 403, and the locking rod 404 at the end away from the linkage rod 403 has a smooth mirror surface.

[0043] By adopting the above technical solution, the arc plate 702 is moved during the movement of the annular plate 204. During the movement of the arc plate 702, the collection groove located on the side of the annular plate 204 near the first spring 304 can be blocked, thereby preventing the dust removal liquid from leaking and the dust from flowing into the space between the guide telescopic tube 601 and the dust removal hood 103. The cone tip of the locking rod 404 away from the linkage rod 403 is set towards the fixing groove 405. The smooth mirror surface reduces the contact friction between the locking rod 404 and the fixing groove 405, preventing jamming and facilitating the quick insertion of the locking rod 404 into the fixing groove 405, thereby improving the stability of the device operation.

[0044] Instructions for use: First, turn on the power to the fan body 102. The fan body 102 generates negative pressure suction. The outside airflow flows in evenly through the guide groove 104 of the dust removal hood 103. The airflow first passes through the filter screen 205, which initially blocks and filters the dust in the airflow. The filtered clean airflow is then discharged into the room through the fan body 102, completing the basic ventilation and dust removal.

[0045] Self-sensing cleaning of the filter screen: When dust accumulates on the surface of the filter screen 205, causing a decrease in permeability, under the negative pressure suction of the fan, the filter screen 205 drives the annular plate 204 to move towards the fan body 102. Then, the filter screen 205 pushes the push rod 305 to move the slider 301. The connecting rope 302 pulls the connecting rod 202 to rotate, making the impeller 203 perpendicular to the airflow direction.

[0046] Automatic dust removal by rotating cleaning rod: The airflow impacts the vertically positioned impeller 203, causing it to rotate. The impeller 203 drives the rotating rod 201 to rotate via the connecting rod 202. The rotating rod 201 drives the cleaning rod 208 to rotate along the surface of the filter screen 205 via the elastic telescopic tube 206 and the mounting ring 207, scraping the dust off the surface of the filter screen 205 to the area of ​​the annular plate 204. At the same time, the locking component 4 automatically locks the slider 301 to ensure that the angle of the impeller 203 is fixed and the cleaning rod is fully cleaned.

[0047] Automatic dust collection: During the movement of the filter screen 205, the second magnet 504 on the annular plate 204 moves away from the first magnet 503 on the sealing plate 502. After the magnetic force weakens, the torque spring 505 drives the sealing plate 502 to rotate, and the collection groove opens. The dust scraped off by the rotating cleaning rod 208 enters the collection box 501 along the collection groove under the action of centrifugal force, realizing the automatic collection of dust and preventing dust from re-attaching to the filter screen 205.

[0048] Automatic dust suppression and prevention of secondary dust: During the movement of the filter screen 205 and the annular plate 204, the guide telescopic tube 601 extends and retracts with them, using the pressure difference to draw liquid from the collection box 501, and enters the cavity 602 through the liquid inlet valve 606 and the first one-way valve 607; after the pressure in the cavity 602 increases, the liquid flows into the dust suppression tank 603 through the liquid drain valve 604, and is sprayed into the collection box 501 through the dust suppression hole to wet and suppress the collected dust, so that the dust adheres to the surface of the filter plate 605, and completely avoids secondary dust.
