Description

Technical Field

[0001] This utility model relates to the technical field of hard surface cleaning machines, specifically to a hard surface cleaning device with an adsorption device. Background Technology

[0002] For tasks such as sanding and polishing certain flat surfaces during renovations, lightweight portable tools are typically used. These tools utilize the high-speed rotation of a cleaning disc to create a smooth, flat surface on the floor or wall. For ease of use, these are usually mounted on wheeled mobile devices, with a motor driving the cleaning disc for sanding or polishing. However, it's rare to use the same equipment for brushing. When sanding or polishing hard surfaces, the high-speed rotation of the cleaning disc removes unevenness, easily stirring up dust and other debris, creating a harsh working environment that affects work performance and personal health. Therefore, some equipment is further equipped with vacuum cleaners to collect and dispose of the dust and debris. However, considering many existing similar devices, the dust extraction mechanism is usually located behind the cleaning disc. This means that after the cleaning disc has polished or abraded the surface, the device needs to move forward before the suction mechanism at the rear absorbs the dust. Sometimes, to prevent the collection box from scratching the floor, the dust needs to be drawn upwards and collected into the device. This requires overcoming gravity and using relatively long pipes, necessitating a higher negative pressure from the suction mechanism. Furthermore, this method typically only absorbs dust from the rear simultaneously; dust from other directions of the cleaning disc may still be stirred up during polishing, affecting the working environment. Utility Model Content

[0003] To address the problems existing in the prior art, the present invention aims to provide a hard surface cleaning device with an adsorption unit. This invention features a reasonable design, compact structure, shorter and more targeted dust adsorption path, and significantly reduced output power of the adsorption mechanism.

[0004] The present invention discloses a hard surface cleaning device with an adsorption device, comprising a main body, a cleaning disc rotatably connected to the front side of the main body, a drive mechanism for driving the cleaning disc to rotate inside the main body, a collection box provided at the rear side of the main body, an adsorption mechanism connected above the collection box, a baffle provided on the main body corresponding to the position of the cleaning disc, and the baffle covering the periphery of the cleaning disc to form a cleaning space, the front side of the collection box being connected to the cleaning space through the lower part of the drive mechanism, and the adsorption mechanism being used to adsorb dust or sewage generated in the cleaning space into the collection box.

[0005] In one embodiment, the cross-section of the collection box is a right-angled triangle, wherein the plane containing the longer right-angled side corresponds to the adsorption mechanism above, the plane containing the shorter right-angled side is connected to the lower part of the driving mechanism and has a connecting hole, the inclined surface of the collection box corresponds to the ground, and the inclined surface of the collection box is used as a plane, with first rollers respectively provided at the four corners of the plane.

[0006] In one embodiment, the drive mechanism includes a motor and a drive wheel located below and linked to the motor, and a driven wheel is located above the cleaning disc. The drive wheel is linked to the driven wheel and the cleaning disc via a belt.

[0007] In one embodiment, a through hole is formed in the middle of the driven wheel and the cleaning disc to form a hollow structure. A knob is provided above the position of the main body corresponding to the through hole, and the knob is rotatably connected to the outer shell of the main body. The knob is threadedly connected to a screw, and a second roller is provided at the bottom end of the screw. An elastic element is provided between the second roller and the central axis of the driven wheel.

[0008] In one embodiment, a handle is hinged above the adsorption mechanism along the front-rear direction of the main body, and a control switch is also provided above the adsorption mechanism on the main body.

[0011] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0012] 1. This utility model has a reasonable design and compact structure. It can utilize the space at the bottom of the main body to guide the dust generated during grinding and polishing into the collection box. The baffle ensures a dust-free construction environment without affecting the rotation of the cleaning disc. The dust adsorption stroke is shorter and more targeted, greatly reducing the output power of the adsorption mechanism.

[0013] 2. Due to the design of the collection box and the first roller, the collection box will not be worn due to uneven ground during grinding or polishing. When cleaning, the head of the cleaning disc can be lifted up, and the collection box can be taken out and put in for cleaning like a drawer. The cleaning disc can be replaced with different grinding or polishing layers, and even an additional brush layer can be installed for cleaning. With the setting at the second roller, it can adapt to different cleaning methods, making it more convenient to use in practice. Attached Figure Description

Detailed Implementation

[0018] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-3As shown, this utility model discloses a hard surface cleaning device with an adsorption device, comprising a main body 1, a cleaning disc 2 rotatably connected to the front side of the main body 1, a drive mechanism 3 for driving the cleaning disc 2 to rotate inside the main body 1, a collection box 4 provided on the rear side of the main body 1, an adsorption mechanism 5 connected above the collection box 4, a baffle 6 provided on the main body 1 corresponding to the position of the cleaning disc 2, and the baffle 6 covering the outer periphery of the cleaning disc 2 to form a cleaning space, the front side of the collection box 4 being connected to the cleaning space through the lower part of the drive mechanism 3, and the adsorption mechanism 5 being used to adsorb dust or sewage generated in the cleaning space into the collection box 4. This utility model has a reasonable design and compact structure. It can utilize the bottom space of the main body 1 to guide the dust generated during grinding and polishing into the collection box 4. The baffle 6 ensures a dust-free construction environment without affecting the rotation of the cleaning disc 2. The cleaning space it forms effectively limits the splashing of dust or sewage, and it is easier for the adsorption mechanism 5 to adsorb the dust or sewage from the rear, i.e., the space below the drive mechanism 3. The adsorption mechanism 5 can use a brushless motor to generate negative pressure and adopt stepless speed regulation technology, so that the speed of this fan is smoothly and continuously adjustable without fixed gear restrictions. The adsorption stroke of dust or water stains is shorter and more targeted. It does not need to pass through various curved pipes, etc., and basically stays on the bottom plane of the main body 1, which greatly reduces the output power of the adsorption mechanism.

[0021] Specifically, to keep the collection box 4 and other structures away from the ground during cleaning, the cross-section of the collection box 4 is a right-angled triangle. The plane containing the longer right-angled side corresponds to the upper adsorption mechanism 5, and the plane containing the shorter right-angled side connects to the lower part of the drive mechanism 3 and has a connecting hole. The inclined surface of the collection box 4 corresponds to the ground. In actual installation, a mounting plate can be first set on the rear side of the original main body 1, and then the adsorption mechanism 5 can be fixed with the mounting plate as a reference. The adsorption mechanism 5 can be a vortex fan or similar device, and the collection box 4 can be detachably installed. The collection box 4 can be slidably installed in a drawer-like manner, forming a corner position through the collection box 4, where dust is adsorbed and falls into the collection box 4. In addition, with the inclined surface of the collection box 4 as a plane, first rollers 8 are respectively set at the four corners of this plane. When it is necessary to empty the dust in the collection box 4, the four first rollers 8 can be used as supports to move the entire device to a suitable position, and then the collection box 4 can be removed to complete the cleaning of the collection box 4. During the adsorption process, the baffle 6 will enclose the cleaning space to form a relatively sealed space, so as to facilitate the adsorption of the adsorption mechanism 5. The bottom of the baffle 6 is equipped with a brush 61, which can better block dust from flying. The rear side of the baffle 6 is also equipped with a ventilation hole 62 that is connected to the cleaning space, so that the negative pressure generated by the adsorption mechanism 5 can be connected to the outside, avoiding the smooth surface after polishing from adsorbing with the baffle 6 and generating additional resistance.

[0022] Furthermore, the drive mechanism 3 includes a motor 31 and a drive wheel 32 located below the motor 31 and linked to it. A driven wheel 33 is located above the cleaning disc 2. The drive wheel 32 is linked to the driven wheel 33 and the cleaning disc 2 via a belt. The rotation of the cleaning disc 2 mainly utilizes a pulley and other structures to ensure the high-speed rotation and stability of the cleaning disc 2. The pulley structure is not easily affected by dust, and the dust can be sucked away by the negative pressure generated in the collection box 4 by the adsorption mechanism 5. In addition, a through hole is opened in the middle of the driven wheel 33 and the cleaning disc 2 to form a hollow structure. A knob 9 is located above the position of the through hole on the main body 1, and the knob 9 is rotatably connected to the outer shell of the main body 1. The knob 9 is threadedly connected to a screw 10, and a second roller 11 is located at the bottom end of the screw 10. An elastic element 7 is provided between the second roller 11 and the central axis of the driven wheel 33. The additional knob 9 controls the height of the second roller 11, working in conjunction with the elastic element 7 to fine-tune the cleaning depth of the cleaning disc 2. Specifically, there are three scenarios: When the knob 9 rotates relative to the outer casing, pushing the second roller 11 out using the screw 10, the elastic potential energy generated by the spring-like design of the elastic element 7 provides a downward pulling force to the driven roller 33 and the cleaning disc 2. Combined with their own gravity, this allows for deeper grinding or polishing. When the knob 9 controls the second roller 11 to retract upwards until the elastic element 7 is in a free state, the cleaning disc 2 relies solely on gravity, suitable for grinding or polishing shallower hard surfaces. Similarly, when the second roller 11 is fully upward-loaded, it provides a certain upward force, reducing the gravity of the cleaning disc 2, thus making it suitable for shallower polishing or brush cleaning. Therefore, this device uses a linkage mechanism with pulleys, allowing both the driven roller 33 and the cleaning disc 2 to have a certain height for self-adjustment. Combined with the baffle 6, this creates a dust-free working environment.

[0023] Furthermore, the cleaning disc 2 is detachably connected to the driven wheel 33, and a connector 13 is threadedly connected to the center of the cleaning disc 2. The connector 13 is used to install a brush layer at the bottom of the cleaning disc 2. The cleaning disc 2 can be replaced with different cleaning discs, such as a sanding layer or a polishing layer, for different types of floors. The height of the cleaning disc 2 can be adjusted in conjunction with the self-adjusting structure mentioned above to adapt to different cleaning conditions, from deep to shallow sanding and polishing. The brush layer is installed at the bottom of the cleaning disc 2 through the threaded connection of the connector 13. At the same time, the protrusions of the original cleaning disc 2 are used to further fix the softer brush layer. Water can also be added to wash the surface to further clean the sanded or polished floor.

[0024] In one embodiment, a handle 12 is hinged to the upper part of the adsorption mechanism 5 along the front-rear direction of the main body 1, and a control switch 14 is also provided on the upper part of the main body 1 corresponding to the adsorption mechanism 5. The user can tilt the front of the entire device by controlling the hinge of the handle 12 to facilitate the replacement of the cleaning disc 2, or directly push the device to move it. The controller on it controls each component in the device to facilitate the user's operation of the device. The control switch 14 of the adsorption mechanism 5, i.e., the vortex fan, is located on the top of the outer shell of the main body 1 corresponding to the collection box 4, so that the user can independently control the dust collection function of the collection box 4 and adjust the suction power.
