Description

Technical Field

[0001] This invention relates to the technical field of dust suppression devices for road construction, and more specifically, to a dust suppression device and method for road construction. Background Technology

[0002] With the acceleration of urbanization and the continuous advancement of infrastructure construction, road construction, while supporting economic development, has also triggered serious dust pollution problems, affecting the quality of life of surrounding residents and posing a threat to public health. Dust mainly originates from earthwork operations, construction material handling, transport vehicle traffic, and wind. Therefore, developing efficient dust suppression devices has become a crucial issue that the construction industry urgently needs to address.

[0003] A search revealed a Chinese patent (publication number: CN114345055A) proposing a dust suppression device and its usage method for road construction. The device includes a base, a hydraulic rod, and side plates. The side plates are located on both the left and right sides of the base. Supports are installed on both the left and right sides of one side wall of each side plate, and the hydraulic rod is mounted on each support. The beneficial effect is that, by incorporating red and green indicator lights, during the device's operation, the support, support, hydraulic rod, and mounting arm work together to reduce dust on vehicles at a car wash station. The retraction of the hydraulic rod on the mounting arm causes the side plates to rotate on the base via support one. During the retraction, the upper and lower ends of the hydraulic rod can rotate on support one and support two respectively, thereby rotating the side plates to clean and reduce dust on the upper part of the vehicle body, thus increasing the cleaning range of the device.

[0004] While the aforementioned patents can achieve the detection function, they still have the following shortcomings in actual use:

[0005] In practical applications, the above-mentioned solutions rely on external manual commands or preset sensor signals to initiate and control the cleaning and drying actions. This "external command triggering" mode has significant drawbacks in complex and harsh construction environments: the control system (such as electronic sensors, controllers, and circuits) is exposed to high humidity, high dust, and mud splashes for a long time, making it prone to malfunction, damage, or signal interference, resulting in reduced equipment reliability and increased failure rate.

[0006] Therefore, we have made improvements to this by proposing a dust suppression device and method for road construction in order to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a dust suppression device and method for road construction, so as to solve the problems mentioned in the background art.

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0015] As a preferred technical solution of this application, the air intake assembly includes two air boxes disposed on both sides of the top of the protective chamber and multiple exhaust fans installed inside the air boxes. The air intake of the exhaust fans is equipped with a first filter screen, and the air outlets on both sides of the air boxes are connected to the air inlets of multiple sets of jets on both sides through air supply pipes.

[0018] The hydraulic rod pushes the transmission ring to move, and the second transmission rod drives the guide plate to rotate in opposite directions, controlling the air pressure at the air outlet of the air pipe.

[0019] As a preferred technical solution of this application, the control triggering component includes a first drive chamber opened inside the water storage tank, a second drive chamber opened on both sides inside the water storage tank, a slot opened on both sides of the second drive chamber, a drive plate disposed inside the first drive chamber, and a locking frame disposed inside the second drive chamber.

[0024] As a preferred technical solution of this application, a circulating water impurity removal component is further provided between the water circuit control component and the water storage tank. The circulating water impurity removal component includes a filter pipe installed on the first water pumping pipe, a first motor installed on the top of the filter pipe, a second filter screen installed on the inside of the filter pipe, a spiral blade installed at the output end of the first motor, and a storage bottle installed at the bottom outlet of the filter pipe.

[0025] The first motor rotates the spiral blades inside the second filter screen, pushing the impurities filtered out by the second filter screen into the storage bottle.

The output end of the limiting cover is provided with a driving gear. The driving gear and the rotating gear ring are connected by a driven gear. The rotating gear ring is provided with multiple second guide grooves. The fixing plate is provided with multiple first guide grooves. Multiple adjusting plates are also provided between the rotating gear ring and the fixing plate. A second limiting rod and a first limiting ring are respectively installed on the adjusting plate from the inside to the outside. The first limiting ring is connected to the second guide groove, and the second limiting rod is connected to the first guide groove.

[0027] As a preferred technical solution of this application, a sieve plate is installed inside the water storage tank. The sieve plate is installed above the water inlet of the first water pumping pipe for screening large particulate impurities.

[0028] As a preferred technical solution of this application, a method of using a dust suppression device for road construction specifically includes the following steps:

[0029] S1: The engineering vehicle first drives into the protective compartment. During the process, the drive plate on the side where the vehicle enters is pressed down. As the drive plate moves down, the internal hydraulic oil is first supplied to the first and second drive compartments on the other side. However, the drive plate is limited by the locking frame and cannot move up directly. The pressure is first applied to the locking frame, which moves away from the drive plate and cancels the locking of the drive plate. Then the drive plate can move up. At the same time, as the drive plate moves up, since the top of the drive plate is not under force, the spring on the side where the vehicle enters pushes the locking frame towards the slot with the side wall of the second drive compartment as the stress point, and moves it into the slot. At the same time, the hydraulic oil inside the second drive compartment continues to be supplied to the first and second drive compartments on the side where the vehicle exits. Then the locking frame on the side where the vehicle enters is inserted into the slot to lock and limit the drive plate.

[0030] S2: Simultaneously, before the vehicle enters the protective compartment, the exhaust fan is manually turned on. The exhaust fan draws in outside air through the first filter and delivers it into the air box. During the process, the air is filtered through the first filter. Then, the air in the air box is diverted into the jet injector through the air supply pipe. The jet injector then delivers the gas into the diversion pipe for further diversion. Finally, the gas is sprayed out through the air outlet adjustment component to clean the dust from the vehicle inside.

[0031] S3: During the upward movement of the drive plate on the side where the vehicle leaves, the drive rack moves upward synchronously, thereby driving the two drive gears on the outside to rotate synchronously. Through the drive gears, the first transmission rod drives the control plate and the connecting hole to rotate inside the sealing cover, rotating the connecting hole to a vertical state, connecting the first and second water pipes on both sides respectively. Thus, during the jet ejection process, the negative pressure generated at the throat allows the first and second water pipes to draw the circulating water at the bottom of the water tank and the stored water in the water storage tank respectively, mix them at the throat, and then spray them out into the diversion pipe.

[0032] S4: When the water mist is sprayed out, the hydraulic rod drives the transmission ring to move on the outside of the air outlet pipe, which in turn drives the guide plate to rotate in the opposite direction through the second transmission rod, thereby adjusting the size of the air outlet position and allowing the air pressure at the air outlet to be flexibly adjusted according to the amount of dust attached to the vehicle.

[0033] S5: During the process of the jet pumping the circulating water, the circulating water carrying impurities enters the filter tube and is transported out through the second filter screen. At the same time, the first motor drives the spiral blades to rotate inside the second filter screen, thereby pushing the impurities filtered by the second filter screen into the storage bottle through the spiral blades.

[0034] S6: After the ejector draws circulating water and stored water into the ejector throat, the second motor can use the driving gear and driven gear to rotate the rotating gear ring inside the limiting cover. Then, the second guide groove drives the first limiting ring to rotate, while the first guide groove limits the second limiting rod. This causes the first limiting ring to rotate on its own axis while revolving around the central axis, so that the first limiting rings rotate in close contact with each other. This adjusts the size of the air outlet between the first limiting rings, thereby controlling the air pressure in the ejector throat and controlling the amount of water entering the ejector.

[0035] In the scheme of this application:

[0036] 1. By utilizing the entry and exit of vehicles as a driving force to control the connection and closure of the waterway, the waterway can be opened and closed in a timely manner when vehicles enter and exit. This mechanical transmission replaces electronic control in harsh environments, enabling real-time response to vehicle actions. This ensures timely reduction of dust during construction and avoids unnecessary water waste, thus being more environmentally friendly. Secondly, using mechanical transmission to control the waterway reduces reliance on electronic components, enhances system reliability and stability, and reduces equipment failures and maintenance costs.

[0037] 2. By shutting off the water circuit when the vehicle hits the drive plate on the exit side, the vent pipe only sprays air, thus achieving vehicle drying. This allows for switching between washing and drying modes, improving operational efficiency and enabling on-the-spot switching according to construction needs. It also saves water resources, reduces costs, and aligns with sustainable development principles. Furthermore, the simplified operating procedure makes it easier for construction personnel to use, reducing the risk of malfunctions, while improving the cleanliness of vehicles and equipment, maintaining their normal operation, and extending their service life.

[0038] 3. By controlling the air outlet adjustment component and the air outlet size control component, the air pressure at the air outlet position of the air pipe and the negative pressure in the throat of the jet injector can be controlled. This allows for adjustment of the air pressure sprayed onto the vehicle's exterior based on the amount of dust adhering to it, and adjustment of the amount of water extracted based on the water storage tank and water collection chamber. This achieves precise dust suppression, adapts to varying environmental conditions, effectively utilizes water resources, and avoids waste. Simultaneously, optimized air pressure and water flow reduce equipment wear and tear, extend its service life, improve construction safety, and reduce the risk of accidents caused by dust.

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] Example:

[0059] Please see Figure 1-17 This embodiment proposes a dust suppression device and method for road construction, including a base plate 11, a protective chamber 1 set on top of the base plate 11, a visual sensor (the visual sensor is prior art, referring to existing commercial visual sensors, and will not be described) installed on the exterior of the protective chamber 1 on the side where the vehicle enters, the visual sensor monitors the amount of dust adhering to the vehicle and uploads the data to the equipment controller to control the operation of subsequent equipment, a water collection chamber 2 set at the bottom of the base plate 11, a connecting pipe 27 set inside the water collection chamber 2, water storage tanks 43 set on both sides of the protective chamber 1, and multiple jets 4 (the jets 4 are prior art, referring to existing venturi tubes, and will not be described) set on both sides of the bottom of the protective chamber 1. The base plate 11 supports and fixes the protective chamber 1 and the water collection chamber 2, and the base plate 11 and the water collection chamber 2 can be disassembled. When a lot of impurities accumulate in the water collection chamber 2, the base plate 11 can be removed to clean the inside of the water collection chamber 2. The method also includes:

[0060] An air intake assembly is located on the outside of the protective chamber 1, and its outlet is connected to the air intake of multiple sets of jet injectors 4 to provide gas support for the equipment. The air intake assembly includes two air boxes 3 located on both sides of the top of the protective chamber 1 and multiple exhaust fans 32 installed inside the air boxes 3. The air inlet of the exhaust fans 32 is equipped with a first filter screen 31. The air outlets on both sides of the air boxes 3 are connected to the air inlets of the multiple sets of jet injectors 4 on both sides through air supply pipes 33. The outside air drawn by the exhaust fans 32 is filtered by the first filter screen 31 before entering the air boxes 3.

[0061] The first filter 31 can be removed from the exhaust fan 32, so that after a period of use, the first filter 31 can be removed from the exhaust fan 32 for cleaning, thereby ensuring the air intake of the exhaust fan 32.

[0062] Multiple sets of air outlet adjustment components are installed inside the protective chamber 1, with their air inlet ends connected to the air outlet ends of the jet ejector 4 to spray out gas. The air outlet adjustment components include multiple diversion pipes 8 installed inside the protective chamber 1, multiple air outlet pipes 81 installed at the bottom of the diversion pipes 8, a transmission ring 83 installed outside the air outlet pipes 81, multiple hydraulic rods 82 installed outside the air outlet pipes 81, and multiple guide plates 85 installed on the side of the air outlet pipes 81 away from the diversion pipes 8. The transmission ring 83 is connected to the air outlet pipes 81 through the hydraulic rods 82, and the transmission ring 83 is connected to the guide plates 85 through a second transmission rod 84. The hydraulic rods 82 push the transmission ring 83 to move, and the second transmission rod 84 drives the guide plates 85 to rotate in opposite directions, controlling the air pressure at the air outlet of the air outlet pipes 81.

[0063] When the vehicle enters the protective compartment 1, the amount of dust adhering to the outside of the vehicle is detected, and the hydraulic rod 82 is controlled to operate based on the detection results to adjust the air pressure at the air outlet of the air pipe 81, thereby controlling the cleaning force.

[0064] Two sets of control triggering components are respectively installed inside the two sides of the water collection tank 2 and connected by a connecting pipe 27. The control triggering components include a first drive chamber 21 opened inside the water collection tank 2, a second drive chamber 24 opened on both sides inside the water collection tank 2, a slot 23 opened on both sides of the second drive chamber 24, a drive plate 22 installed inside the first drive chamber 21, and a locking frame 25 installed inside the second drive chamber 24. The locking frame 25 is connected to the side wall of the second drive chamber 24 by a spring 26, and the spring 26 pushes the locking frame 25 towards the first drive chamber 21 with the second drive chamber 24 as the stress point to lock it into the slot 23. The two sides of the first drive chamber 21 and the second drive chamber 24 are connected by a connecting pipe 27.

[0065] The control trigger components on both sides have the same structure. The first drive chamber 21 and the second drive chamber 24 are connected to the drive end through the connecting pipe 27. The pressure generated by the flow of hydraulic oil inside drives the drive plate 22 on the corresponding side to move up and down. During the movement of the drive plate 22 on the side where the vehicle leaves, the water circuit control component on the outside is driven to run. The water circuit in the control device is incorporated into the air circuit.

[0066] The locking bracket 25 engages and limits the drive plate 22 only after the drive plate 22 has moved down, thereby using the vehicle's entry and exit to make the drive plates 22 on both sides move back and forth, corresponding to the opening and closing of the water passage during the process.

[0067] The water circuit control components are located on both sides of the protective chamber 1 and are driven by the control trigger component to control the opening and closing of the water circuit. The water circuit control components include limit frames 6 installed on both sides of the protective chamber 1, drive racks 61 located inside the limit frames 6, two drive gears 62 located inside the limit frames 6, a first transmission rod 63 installed inside the drive gears 62, multiple control discs 65 installed outside the first transmission rods 63, and a sealing cover 64 located outside the control discs 65. The control discs 65 have connecting holes 66 inside, which cooperate with the sealing cover 64 to connect the top and bottom of the sealing cover 64. The drive racks 61 are connected to the drive plate 22 on the side where the vehicle exits, and the drive racks 61 are meshed with the drive gears 62. The top sealing cover 64 is installed in the middle section of the second water suction pipe 42, and the bottom sealing cover 64 is installed in the middle section of the first water suction pipe 41.

[0068] The water inlets on both sides of the jet injector 4 are connected to the water storage tank 43 and the water accumulation chamber 2, respectively, and the opening and closing of the connecting section is controlled by the water circuit control component.

[0069] The jet ejector 4 is connected to the water storage tank 43 through the second water pumping pipe 42, and the jet ejector 4 is connected to the water accumulation tank 2 through the first water pumping pipe 41.

[0070] The lifting and lowering of the drive plate 22 on the side where the vehicle leaves causes the drive racks 61 on both sides to lift and lower, thereby driving the drive gear 62 to rotate. This is then transmitted via the first transmission rod 63, causing the control plate 65 and the connecting hole 66 inside the sealing cover 64 to rotate synchronously. After the drive plate 22 on the side where the vehicle leaves moves down, the connecting hole 66 inside the control plate 65 is in a horizontal state. At this time, the first water suction pipe 41 and the second water suction pipe 42 are in a closed state, and the water inside does not circulate. After the drive plate 22 moves up, the connecting hole 66 is in a vertical state, and the first water suction pipe 41 and the second water suction pipe 42 are in a connected state. At this time, the water in the water storage tank 43 and the water accumulation chamber 2 can be extracted by the jet injector 4.

[0071] A circulating water impurity removal component is also provided between the water circuit control component and the water storage tank 2. The circulating water impurity removal component includes a filter pipe 5 installed on the first water pumping pipe 41, a first motor 52 installed on the top of the filter pipe 5, a second filter screen 51 installed on the inside of the filter pipe 5, a spiral blade 53 installed at the output end of the first motor 52, and a storage bottle 54 installed at the bottom outlet of the filter pipe 5.

[0072] The first motor 52 rotates the spiral blade 53 inside the second filter screen 51, pushing the impurities filtered out by the second filter screen 51 into the storage bottle 54.

[0073] Wastewater generated during vehicle washing flows into the water collection tank 2 through the bottom plate 11 and is extracted by the first water pumping pipe 41 through the jet 4. During the process, the wastewater passes through the filter pipe 5 and is filtered through the second filter screen 51 before being transported into the jet 4, thereby reducing the impurity content in the wastewater.

[0074] The inner throat of the jet ejector 4 is also provided with an air port size control component. The air port size control component includes a second motor 71 installed at the bottom of the jet ejector 4, a limiting cover 7 installed at the throat of the jet ejector 4, a rotating gear ring 75 installed inside the limiting cover 7, and a fixing plate 710 installed inside the limiting cover 7. The output end of the limiting cover 7 is provided with a drive gear 73. The drive gear 73 is connected to the rotating gear ring 75 through a driven gear 74. The rotating gear ring 75 is provided with multiple second guide grooves 76, and the fixing plate 710 is provided with multiple first guide grooves 72. Multiple adjusting plates 77 are also provided between the rotating gear ring 75 and the fixing plate 710. The adjusting plates 77 are respectively provided with a second limiting rod 79 and a first limiting ring 78 from the inside to the outside. The first limiting ring 78 is connected to the second guide groove 76, and the second limiting rod 79 is connected to the first guide groove 72.

[0075] The second motor 71 drives the rotating gear ring 75 to rotate via the driving gear 73 and the driven gear 74. At the same time, the second guide groove 76 drives the first limiting ring 78 to revolve, so that the adjusting plate 77 revolves between the rotating gear ring 75 and the fixed plate 710. Meanwhile, the first guide groove 72 limits the second limiting rod 79, so that the adjusting plate 77 rotates on its own axis while revolving around the ring.

[0076] A screen plate 12 is installed inside the water collection tank 2. The screen plate 12 is installed above the water inlet of the first water pumping pipe 41 to screen large particulate impurities. The screen plate 12 screens large particulate impurities in the wastewater entering the water collection tank 2, reducing the workload of the circulating water impurity removal component.

[0077] A method for using a dust suppression device for road construction includes the following steps:

[0078] S1: The engineering vehicle first drives into the protective compartment 1. During the process, the drive plate 22 on the side where the vehicle enters is pressed down. As the drive plate 22 moves down, the internal hydraulic oil is first delivered to the first drive compartment 21 and the second drive compartment 24 on the other side. However, the drive plate 22 is limited by the locking frame 25 and cannot move up directly. The pressure is first applied to the locking frame 25, and the locking frame 25 moves away from the drive plate 22, canceling the locking of the drive plate 22. Then the drive plate 22 can move up. At the same time, during the upward movement of the drive plate 22, since the top of the drive plate 22 is not under force, the spring 26 on the side where the vehicle enters pushes the locking frame 25 towards the locking groove 23 with the side wall of the second drive compartment 24 as the stress point, and moves it into the locking groove 23. At the same time, the hydraulic oil inside the second drive compartment 24 continues to be delivered to the first drive compartment 21 and the second drive compartment 24 on the side where the vehicle exits. Then the locking frame 25 on the side where the vehicle enters is inserted into the locking groove 23 to lock and limit the drive plate 22.

[0079] S2: Simultaneously, before the vehicle enters the protective compartment 1, the exhaust fan 32 is manually turned on. The exhaust fan 32 draws in the outside air through the first filter 31 and delivers it into the air box 3. During the process, the air is filtered through the first filter 31. Then, the air in the air box 3 is diverted into the jet injector 4 through the air supply pipe 33. The jet injector 4 delivers the gas into the diversion pipe 8 for diversion. Then, it is sprayed out through the air outlet adjustment component to clean the dust from the vehicle inside.

[0080] S3: During the upward movement of the drive plate 22 on the side where the vehicle leaves, the drive rack 61 moves upward synchronously, thereby driving the two drive gears 62 on the outer side to rotate synchronously. Through the drive gears 62, the first transmission rod 63 drives the control plate 65 and the connecting hole 66 to rotate inside the sealing cover 64, rotating the connecting hole 66 to a vertical state, connecting the first water pipe 41 and the second water pipe 42 on both sides respectively. Thus, during the jet spraying process of the jet ejector 4, the negative pressure generated at the throat allows the first water pipe 41 and the second water pipe 42 to draw the circulating water at the bottom of the water tank 2 and the stored water in the water storage tank 43 respectively, mix them at the throat, and then spray them out into the diversion pipe 8.

[0081] S4: When the water mist is sprayed out, the hydraulic rod 82 drives the transmission ring 83 to move outside the air outlet pipe 81, so that the guide plate 85 can be driven to rotate in opposite directions through the second transmission rod 84, thereby adjusting the size of the air outlet position and making the air pressure of the air outlet flexibly adjustable according to the amount of dust attached to the vehicle.

[0082] S5: During the process of the ejector 4 extracting circulating water, the circulating water carrying impurities enters the filter tube 5 and is transported out through the second filter screen 51. At the same time, the first motor 52 drives the spiral blades 53 to rotate inside the second filter screen 51, thereby pushing the impurities filtered by the second filter screen 51 into the storage bottle 54 through the spiral blades 53.

[0083] S6: After the ejector 4 draws circulating water and stored water into the throat of the ejector 4, the second motor 71 can rotate the rotating gear ring 75 within the limiting cover 7 using the driving gear 73 and driven gear 74. Then, the second guide groove 76 drives the first limiting ring 78 to rotate, while the first guide groove 72 limits the second limiting rod 79, so that the first limiting ring 78 rotates on its own axis while revolving around the central axis, so that the first limiting rings 78 rotate in close contact with each other, thereby adjusting the size of the air outlet between the first limiting rings 78, thereby controlling the air pressure in the throat of the ejector 4 and controlling the amount of water entering the ejector 4.

10. A method of using a dust suppression device for road construction according to any one of claims 1-9, characterized in that, Specifically, the following steps are included: S1: The engineering vehicle first drives into the protective compartment (1). During the process, the drive plate (22) on one side of the vehicle is pressed down. As the drive plate (22) moves down, the internal hydraulic oil is first delivered to the first drive compartment (21) and the second drive compartment (24) on the other side. However, the drive plate (22) is limited by the locking frame (25) and cannot move up directly. The pressure is first applied to the locking frame (25), and the locking frame (25) moves away from the drive plate (22), canceling the locking of the drive plate (22). After that, the drive plate (22) can move up. Meanwhile, as the drive plate (22) moves upward, since the top of the drive plate (22) is not under force, the spring (26) on the vehicle driving side pushes the locking frame (25) towards the slot (23) with the side wall of the second drive compartment (24) as the stress point, and moves towards the inside of the slot (23). At the same time, the hydraulic oil inside the second drive compartment (24) continues to be delivered to the first drive compartment (21) and the second drive compartment (24) on the vehicle driving out side. Then, the locking frame (25) on the vehicle driving side inserts into the slot (23) to lock and limit the drive plate (22). S2: At the same time, before the vehicle enters the protective compartment (1), the exhaust fan (32) is turned on manually. The exhaust fan (32) draws in the outside air through the first filter (31) and delivers it into the air box (3). During the process, the air is filtered through the first filter (31). Then the air in the air box (3) is diverted into the jet injector (4) through the air supply pipe (33). The gas is delivered into the diversion pipe (8) through the jet injector (4) for diversion. Then it is sprayed out through the air outlet adjustment component to clean the dust inside the vehicle. S3: During the process of the drive plate (22) moving up on the side of the vehicle, the drive rack (61) moves up synchronously, thereby driving the two drive gears (62) on the outside to rotate synchronously. Through the drive gears (62), the first transmission rod (63) drives the control plate (65) and the connecting hole (66) to rotate inside the sealing cover (64), and rotates the connecting hole (66) to a vertical state, connecting the first water pipe (41) and the second water pipe (42) on both sides respectively. Thus, during the jet spraying process of the jet ejector (4), the negative pressure generated in the throat allows the first water pipe (41) and the second water pipe (42) to draw out the circulating water at the bottom of the water tank (2) and the stored water in the water storage tank (43) respectively, mix them in the throat, and then spray them out into the diversion pipe (8). S4: When the water mist is sprayed out, the hydraulic rod (82) drives the transmission ring (83) to move outside the air outlet pipe (81), so that the guide plate (85) can be driven to rotate in opposite directions through the second transmission rod (84), thereby adjusting the size of the air outlet position and making the air pressure of the air outlet flexibly adjustable according to the amount of dust attached to the vehicle. S5: During the process of the jet pump (4) extracting circulating water, the circulating water carrying impurities enters the filter tube (5) and is transported out through the second filter screen (51). At the same time, the first motor (52) drives the spiral blades (53) to rotate inside the second filter screen (51), thereby pushing the impurities filtered by the second filter screen (51) into the storage bottle (54) through the spiral blades (53). S6: After the ejector (4) draws circulating water and stored water into the throat of the ejector (4), the second motor (71) can use the driving gear (73) and driven gear (74) to rotate the rotating gear ring (75) in the limiting cover (7). Then, the second guide groove (76) drives the first limiting ring (78) to rotate, while the first guide groove (72) limits the second limiting rod (79), so that the first limiting ring (78) rotates on its own axis while revolving around the center, so that the first limiting rings (78) rotate in close contact with each other, thereby adjusting the size of the air outlet between the first limiting rings (78), thereby controlling the air pressure in the throat of the ejector (4) and controlling the amount of water entering the ejector (4).
