Description

Technical Field

[0001] This utility model belongs to the field of workshop dust collection technology, specifically relating to a mobile dust removal device with a rotating brush for use in clean workshops. Background Technology

[0002] In cleanroom or laboratory environments, the cleanliness of the air, floors, and walls directly affects product quality and experimental accuracy. Therefore, mobile cleaning equipment equipped with vacuum systems is commonly used to clean floors and work areas to remove dust particles, fibers, and other minute impurities. Existing cleanroom mobile cleaning equipment typically consists of a base, a dust collection device, a vacuum hose, and a handheld vacuum head. The operator moves the equipment across the floor by moving the base, and the negative pressure device creates suction to draw dust into the dust collection bin for filtration and collection. However, traditional equipment still suffers from inconvenient operation and low maintenance efficiency during use.

[0003] Most existing mobile purification devices use a fixed dust collection cylinder structure. After use, a large amount of dust accumulates inside the dust collection cylinder, significantly increasing its weight. Furthermore, the bottom of the device often has a roller structure, causing the dust collection cylinder to be suspended in the air during installation and removal. Due to the lack of auxiliary support structures, operators often need to manually lift the dust collection cylinder when replacing or cleaning it, which can lead to high labor intensity, unstable operation, or dust leakage due to tilting. This is neither ergonomic nor conducive to purification efficiency.

[0004] While some equipment adds support structures under the dust collection cylinder to reduce the difficulty of disassembly and assembly, most designs lack lifting and adjustment mechanisms. This means that the dust collection cylinder still needs to be adjusted multiple times when connecting to negative pressure pipelines or disassembling for cleaning, making operation complicated. In addition, when the bottom of the dust collection cylinder is not in full contact with the ground, its center of gravity is too high, making it prone to swaying during movement or vibration, affecting the stability of the equipment operation.

[0005] Existing vacuum systems mostly rely on suction power alone when cleaning stubborn dust, and their effectiveness is limited when removing strongly adhered particles or electrostatically attracted substances. Some devices attempt to use rotating brushes for auxiliary cleaning, but the brush drive mechanism and the vacuum system are often installed separately, resulting in a messy layout of wires and hoses, which can easily affect operational flexibility and safety. Utility Model Content

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a mobile dust removal device with a rotating brush for cleanrooms. This mobile device with a rotating brush is easy to operate and has a better cleaning effect, thereby improving the user experience and purification efficiency of the equipment.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A mobile dust removal device with a rotating brush for a cleanroom includes a mobile base plate, with rollers at the four corners of the bottom of the mobile base plate, a negative pressure unit fixed to the rear side of the upper surface of the mobile base plate, and a handle fixed to the top of the negative pressure unit.

[0009] The movable base plate has a U-shaped through groove with an open front side on its front side. A sliding plate is vertically slidably installed on the front surface of the negative pressure machine body. A supporting base plate is provided at the bottom of the sliding plate, and the center of the supporting base plate coincides with the center of the U-shaped through groove. A dust collection cylinder is placed on the top of the supporting base plate, and the top of the dust collection cylinder is connected to the output end of the negative pressure machine body through a through connection.

[0010] A flexible hose is connected to the front of the dust collection cylinder, and a handle is provided at the end of the hose. A suction head is installed at the end of the handle.

[0011] Furthermore, the bottom of the suction head is open, a brush is rotatably mounted on the front inner side of the suction head, a motor is fixed on one side of the suction head, and one end of the brush is mounted on the output shaft of the motor.

[0012] Furthermore, the upper surface of the movable base plate is symmetrically provided with columns on the front side, and bolts are screwed through the top of each of the two columns. The bolts on the surface of the columns on both sides are used to fix the dust collection cylinder in place.

[0013] Furthermore, a groove is vertically formed at the center of the front surface of the negative pressure machine body, a toothed plate is provided on the top of the slide plate, and T-shaped slide bars are provided on the back of both the slide plate and the toothed plate, with the T-shaped slide bars sliding inside the groove.

[0014] Furthermore, the front surface of the negative pressure machine body is provided with two protruding plates, and a rotating shaft is horizontally rotatably installed between the two protruding plates. The surface of the rotating shaft is provided with gears, and the gears mesh with the gear plates.

[0015] Furthermore, one end of the rotating shaft passes through the convex plate, a rotating handwheel is provided at the end of the rotating shaft, and a ratchet is installed on the surface of the rotating shaft, with the ratchet positioned outside one of the convex plates.

[0016] Furthermore, one of the convex plates has a protrusion on its outer side, and a slide rod slides horizontally through the surface of the protrusion. A wedge block is provided at one end of the slide rod and a pull plate is provided at the other end. The wedge block engages with a ratchet.

[0017] Furthermore, a spring is fitted onto the surface of the slide bar, the spring being positioned between the protrusion and the wedge block, and the spring applying a thrust to the protrusion in the ratchet direction.

[0018] Furthermore, positioning bolts are symmetrically arranged on the upper surface of the support base plate near the side of the slide plate, and the positioning bolts are used to limit the rear side of the dust collection cylinder.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] To address the difficulties and high labor intensity associated with manual lifting during the installation and disassembly of dust collection cylinders in existing purification mobile equipment, this device incorporates a sliding plate and supporting base plate structure on the front surface of the negative pressure unit. The sliding plate achieves controllable lifting and lowering via a sliding groove and gear transmission mechanism. The supporting base plate, in conjunction with a U-shaped through groove, provides load-bearing support when the dust collection cylinder is pushed in, and the gear is raised or lowered by rotating a handwheel, allowing the dust collection cylinder to rise or fall vertically. When disassembly is required, pulling the pull plate disengages the wedge block from the ratchet engagement, allowing the supporting base plate to move downwards under the weight of the dust collection cylinder, facilitating the operator to directly pull out the dust collection cylinder from the front for cleaning or replacement. This structural design effectively reduces the labor intensity of loading and unloading operations and improves installation and maintenance efficiency.

[0021] To address the issues of swaying and unstable positioning caused by the suspended state of traditional dust collection structures during operation, this equipment features symmetrically distributed positioning bolts on the surface of the support base plate. The dust collection cylinder is clamped and fixed by columns and bolts on both sides, ensuring its vertical stability during operation. The support base plate and the T-shaped sliding strips within the chute guide and cooperate to ensure the dust collection cylinder's center of gravity remains stable and does not tilt during lifting and lowering. This structure not only eliminates the problems of displacement and air leakage caused by vibration but also effectively improves the overall operational stability of the equipment and the sealing performance of the negative pressure system.

[0022] Addressing the limitations of traditional vacuum cleaners that rely solely on suction to remove dust and are ineffective at removing firmly adhered particles and static electricity, this device incorporates a rotating brush structure at the bottom of the vacuum cleaner head. Driven by a motor, the brush rotates continuously, and the bristles are made of a conductive fiber blend that prevents static electricity buildup while removing adhered dust. The hollow interior of the vacuum cleaner head forms an air intake chamber connected to a negative pressure unit, allowing dust swept by the rotating brush to be simultaneously drawn into the dust collection cylinder, achieving an integrated "brushing + adsorption" cleaning mode. This design effectively improves the removal efficiency of dust particles from cleanroom floors and corners, enhancing the purification effect.

[0023] To address the issues of poor operational comfort and complex structure leading to an unsatisfactory user experience in existing equipment, this device features a rubber-coated handle at the top of the negative pressure unit, ensuring a comfortable grip for the operator during pushing. The bottom casters utilize a combination of directional and omnidirectional wheels, guaranteeing stability during straight-line movement while improving steering flexibility. The hose employs a spiral-reinforced corrugated structure, providing both excellent flexibility and preventing collapse under negative pressure, resulting in smoother and more reliable vacuuming operations. These improvements significantly enhance the equipment's mobility and ergonomics within cleanrooms, improving the overall convenience and sustainability of cleaning operations.

[0031] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0032] refer to Figures 1 to 5 As shown, a mobile dust removal device with a rotating brush for cleanrooms includes a mobile base plate 1, with rollers at all four corners of the bottom of the base plate 1. A negative pressure unit 12 is fixed to the rear side of the upper surface of the base plate 1, and a handle 13 is fixed to the top of the negative pressure unit 12. Addressing the issues of poor stability and low integration of the negative pressure system in existing cleanroom equipment, the mobile base plate 1 adopts a rectangular metal plate structure to improve overall load-bearing capacity. The bottom rollers are arranged in a combination of two front directional wheels and two rear universal wheels, enabling the device to move in a straight line and turn flexibly, facilitating directional control by the operator using the handle 13. A high-power centrifugal negative pressure fan is installed inside the negative pressure unit 12, which generates a continuous negative pressure airflow to adsorb dust from the dust collection cylinder 2. The handle 13 at the top of the negative pressure unit 12 is composed of a corrosion-resistant metal tube and a rubber sleeve, facilitating manual pushing and reducing operator fatigue during prolonged operation, thus improving human-machine comfort.

[0033] The movable base plate 1 has a U-shaped through groove 11 with an open front side. A sliding plate 5 is vertically slidably mounted on the front surface of the negative pressure unit 12. A supporting base plate 52 is positioned forward at the bottom of the sliding plate 5, and the center of the supporting base plate 52 coincides with that of the U-shaped through groove 11. A dust collection cylinder 2 is placed on top of the supporting base plate 52, and the top of the dust collection cylinder 2 is connected to the output end of the negative pressure unit 12 through a through connection. To address the problems of difficult disassembly and unstable suspended installation of traditional dust collection cylinders, the U-shaped through groove 11 is designed as a through groove structure, with its open front side facilitating the operator to push or pull the dust collection cylinder 2 in from the front of the equipment. The sliding plate 5 is made of thickened material. The steel plate structure, with the surface of the sliding plate 5 cooperating with the sliding groove 14 to form a lifting guide mechanism, allows the dust collection cylinder 2 to rise and fall smoothly in the vertical direction; the support base plate 52 is aligned with the center of the U-shaped through groove 11 to keep the center of gravity of the dust collection cylinder 2 stable during lifting and avoids uneven loading and tilting; the top of the dust collection cylinder 2 is connected to the input end of the negative pressure machine body 12 through a sealing ring, and the sealing connection uses a high-temperature resistant rubber gasket to prevent air leakage and ensure the stable operation of the negative pressure system; through this structural design, the dust collection cylinder 2 can be automatically lifted and quickly positioned during loading and unloading, reducing operating resistance and improving the convenience of disassembly and assembly.

[0034] A flexible hose 3 is connected to the front of the dust collection cylinder 2. A handle 31 is installed at the end of the hose 3, and a suction head 4 is installed at the end of the handle 31. To address the problems of uneven suction distribution and insufficient maneuverability in traditional vacuum cleaner structures, the hose 3 adopts a flexible corrugated tube with a spiral reinforcement structure, which can maintain a stable air cross-sectional area when bending and prevent the vacuum head from being flattened by negative pressure. The power cord of the motor 42 is laid along the upper surface of the hose 3 to simplify the wiring layout. The handle 31 is composed of a lightweight alloy tube and a non-slip rubber coating. The front end is connected to the suction head 4 through a snap-fit ​​structure to ensure quick assembly and disassembly. The suction head 4 is designed as a flat shell with a hollow interior forming an air intake chamber. The air intake chamber is connected to the dust collection cylinder 2 through the hose 3. When the negative pressure unit 12 is started, suction is generated inside the air intake chamber to achieve dust adsorption and transportation. The overall structure of the suction head 4 is compact and lightweight, making it easy for operators to operate for a long time and use flexibly in the confined space of the cleanroom.

[0035] refer to Figure 1 and Figure 5As shown, the bottom of the vacuum head 4 is open, and a brush 41 is rotatably mounted on the front inner side of the vacuum head 4. A motor 42 is fixed on one side of the vacuum head 4, and one end of the brush 41 is mounted on the output shaft of the motor 42. Addressing the problem of low efficiency in removing stubborn dust particles with traditional vacuum heads, the brush 41 uses a mixed bristle design of nylon and conductive fibers, which provides both flexible cleaning capabilities and effectively reduces electrostatic adsorption during rotation. The motor 42 is a small DC drive motor, installed in an independent dustproof chamber on one side of the vacuum head 4, and connected to the end of the brush 41 via a coupling to achieve synchronous rotation of the brush 41. The brush 41 makes slight contact with the ground during rotation, and combined with suction, it can thoroughly remove adhering particles. This structure effectively improves the removal rate of fine dust and electrostatic particles in cleanrooms, ensuring a clean working environment.

[0036] refer to Figure 1 and Figure 2 As shown, symmetrical columns 16 are arranged on the front side of the upper surface of the movable base plate 1. Bolts are screwed through the top of both columns 16, and the bolts on the surface of the two columns 16 are used to fix the dust collection cylinder 2 in place. In order to address the problem that the dust collection cylinder 2 is prone to shaking during operation, the columns 16 adopt a hollow round tube structure with rubber shock-absorbing pads embedded inside, which can buffer the vibration impact during equipment operation. The bolts screwed through the top of the two columns 16 can clamp and fix the dust collection cylinder 2, keeping it stable under high negative pressure suction. The columns 16 and the base plate 1 are welded together to improve the overall rigidity and durability. This design ensures that the dust collection cylinder 2 does not shift during equipment operation, thereby improving the system's sealing and stability.

[0037] refer to Figure 3 and Figure 4 As shown, a groove 14 is vertically formed at the center of the front surface of the negative pressure unit 12. A toothed plate 54 is provided on the top of the slide plate 5. T-shaped slide bars 51 are provided on the back of both the slide plate 5 and the toothed plate 54. The T-shaped slide bars 51 slide inside the groove 14. To address the problem of unstable lifting or guide failure of the slide plate 5, the groove 14 adopts a deepened cast groove structure, and the inner wall is precision ground to reduce frictional resistance. The T-shaped slide bar 51 is a single metal component, and its cross-section matches the groove 14 to ensure the parallelism and perpendicularity of the slide plate 5 during lifting. The toothed plate 54 is installed on the top of the slide plate 5, and precise displacement control can be achieved through the meshing of the gear 61. The setting of this mechanism not only ensures the smoothness of the slide plate 5 sliding up and down, but also provides a reliable transmission foundation for the subsequent lifting of the support base plate 52.

[0038] refer to Figure 3 and Figure 4As shown, the front surface of the negative pressure unit 12 is provided with two protruding plates 15, and a rotating shaft 6 is horizontally rotatably mounted between the two protruding plates 15. A gear 61 is provided on the surface of the rotating shaft 6, and the gear 61 meshes with the toothed plate 54. To address the problem of low control precision in traditional lifting devices, the rotating shaft 6 is made of solid stainless steel and its surface is treated with anti-corrosion electroplating to improve its service life. The gear 61 and the toothed plate 54 are made of high-strength nylon gears, and the tooth surface is ground to ensure smooth meshing and low noise. By manually rotating the rotating shaft 6, the gear 61 can be driven to rotate, thereby achieving precise lifting and lowering of the slide plate 5. This structure realizes the mechanized lifting and lowering control of the supporting base plate 52, which allows the operator to flexibly adjust the height according to the usage requirements.

[0039] refer to Figure 3 As shown, one end of the rotating shaft 6 passes through the protruding plate 15, and a rotating handwheel 63 is provided at the end of the rotating shaft 6. A ratchet 62 is installed on the surface of the rotating shaft 6, and the ratchet 62 is located on the outside of one of the protruding plates 15. In order to address the problem that the skateboard 5 is prone to sliding down after lifting, the ratchet 62 and the rotating handwheel 63 are combined to form an anti-reverse structure. When the handwheel 63 is manually rotated, it can drive the rotating shaft 6 and the gear 61 to rotate to achieve the upward movement, while the ratchet 62 prevents the rotating shaft 6 from rotating in the opposite direction through one-way limit, ensuring that the skateboard 5 can reliably maintain the set height when the operation stops. The rotating handwheel 63 is made of aluminum alloy and covered with a non-slip rubber layer, which is comfortable to operate and has sufficient friction. This design improves the safety and accuracy of the lifting operation.

[0040] refer to Figure 3 As shown, a protrusion 151 is provided on the outer side of one of the convex plates 15. A slide rod 7 slides horizontally through the surface of the protrusion 151. A wedge block 71 is provided at one end of the slide rod 7 and a pull plate 72 is provided at the other end. The wedge block 71 meshes with the ratchet 62. To address the difficulty in releasing the anti-reverse device, a limiting slide hole is provided inside the protrusion 151, and the slide rod 7 moves horizontally within the slide hole. The wedge block 71 is made of hard steel and machined into a wedge surface structure that matches the tooth shape of the ratchet to achieve tight meshing. The pull plate 72 is located at the outer end of the slide rod 7. By manually pulling, the wedge block 71 can be disengaged from the ratchet 62 to achieve the downward unlocking function. This structure can quickly release the locking state when the equipment needs to unload the dust collection cylinder 2, so that the support base plate 52 can be lowered smoothly and disassembled easily.

[0041] refer to Figure 3As shown, a spring 8 is fitted on the surface of the slide bar 7. The spring 8 is positioned between the protrusion 151 and the wedge block 71. The spring 8 applies a pushing force to the protrusion 151 in the direction of the ratchet 62. To address the problem of slippage caused by the wedge block 71 not engaging properly, the spring 8 is made of high-strength alloy steel to maintain continuous elastic pressure. When the pull plate 72 is not under force, the spring 8 automatically pushes the wedge block 71 towards the ratchet 62, keeping the two stably engaged. This design achieves the automatic reset and self-locking function of the anti-reverse mechanism, preventing the slide plate 5 and the support base plate 52 from slipping unexpectedly and ensuring equipment safety.

[0042] refer to Figure 4 As shown, positioning bolts 53 are symmetrically arranged on the upper surface of the support base plate 52 near the slide plate 5. The positioning bolts 53 are used to limit the rear side of the dust collection cylinder 2. In order to address the problem that the dust collection cylinder 2 is prone to deviation during the pushing process, the positioning bolts 53 adopt a cylindrical positioning rod structure with a rubber buffer layer on the surface to prevent direct metal-to-metal collision. The two positioning bolts 53 are symmetrically distributed, which can form a stable rear limit when the dust collection cylinder 2 is pushed in, avoiding tilting and shaking. With the guiding effect of the slide groove 14 and the T-shaped slide bar 51, it is ensured that the dust collection cylinder 2 is always in a vertical state during lifting and disassembly, thereby improving the safety and smoothness of operation.

[0043] The working principle of this utility model is as follows: the hand handle 13 moves the equipment by multiple rollers at the four corners of the bottom of the moving base plate 1. Among them, the two rollers on the rear side are universal wheels. After the dust collection cylinder 2 is installed in place, it moves upward and is then fixed by bolts on the surface of the two side columns 16. The top of the dust collection cylinder 2 is connected to the input end of the negative pressure machine body 12 through the corrugated pipe so that a negative pressure is formed inside the dust collection cylinder 2. A filter bag is provided inside the dust collection cylinder 2. The hose 3 is connected to the dust collection cylinder 2, and a suction head 4 is installed at the end of the handle 31. At this time, the negative pressure inside the dust collection cylinder 2 can make the suction head 4 have suction through the hose 3. The hand handle 31 is used for purification and dust removal. At the same time, the motor 42 is started to control the brush 41 to rotate to remove dust that is not easy to remove. The connecting wire of the motor 42 is distributed along the surface of the hose 3.

[0044] After use, the dust collection cylinder 2 contains a large amount of dust, resulting in a heavy weight. Since the bottom of the movable base plate 1 has rollers, the dust collection cylinder 2 is suspended in the air, making disassembly and installation inconvenient. Therefore, a liftable support base plate 52 is provided on the surface of the negative pressure machine body 12. The support base plate 52 is moved down to the ground. At the same time, since the front of the U-shaped through groove 11 is open, the dust collection cylinder 2 can be pushed into the surface of the support base plate 52 through the front. Then, the dust collection cylinder 2 is moved up by the upward movement of the sliding plate 5, so as to save effort.

[0045] Under normal conditions, due to the pushing force of the spring 8 on the wedge block 71, the wedge block 71 always remains engaged with the ratchet 62, so that the entire shaft 6 can only rotate in one direction. The rotation direction can control the slide plate 5 to move upward, but not downward. Rotating the handwheel 63 controls the gear 61 to rotate. Through the engagement of the gear 61 with the toothed plate 54, the slide plate 5 can be controlled to move upward, thereby controlling the dust collection cylinder 2 pushed into the surface of the support base plate 52 to move upward, making it suspended for easy movement. The two positioning bolts 53 on the surface of the support base plate 52 are used to limit the movement when the dust collection cylinder 2 is pushed in. At the same time, the T-shaped slide bar 51 can only slide vertically along the slide groove 14 to ensure its stable movement. Conversely, after use, the pull plate 72 can be pulled to disengage the wedge block 71 from the ratchet 62. At this time, the support base plate 52 will move to the bottom due to the weight of the dust collection cylinder 2, making it easy to pull out the dust collection cylinder 2 directly, thereby improving the convenience of installing and disassembling the dust collection cylinder 2.

[0046] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
