Description

Technical Field

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

[0002] In existing construction sites, especially for grinding, polishing, and even sweeping hard surfaces such as floors, different mechanical equipment is used, such as existing floor scrubbers and vacuum cleaners. Therefore, designs that combine grinding, polishing, and sweeping into a single device are rare. Furthermore, devices that use a rotating cleaning disc for cleaning typically only have a suction mechanism at the rear, collecting dust only after the front cleaning disc has passed. This easily generates a large amount of dust during disc rotation, affecting the work environment. In addition, because the cleaning disc has a certain horizontal coverage area, users often struggle to achieve good cleaning results on sloping or other hard surfaces. Moreover, the need for baffles to block dust makes horizontally moving machines more susceptible to damage to their casings and other structures when encountering slopes, potentially affecting the cleaning disc's installation position and requiring additional manual repairs and adjustments. Utility Model Content

[0003] To address the problems existing in the prior art, the present invention aims to provide a hard surface cleaning device. This invention features a compact structure that integrates cleaning, adsorption, and collection, and has a more rational force design. In addition to normal horizontal grinding and polishing, it can also transform the entire device into a more planar state, facilitating cleaning for users and enhancing its practicality.

[0004] The present invention provides a hard surface cleaning device, which includes a housing, wherein the housing comprises a detachably connected upper housing and a lower housing, and an mounting plate is formed between the upper housing and the lower housing;

[0005] The lower housing has a collection box located below the mounting plate on its rear side. The front side of the lower housing is detachably fitted with a movable baffle that can move up and down.

The adsorption device is connected to the collection box, and the driving device is linked to the cleaning disc.

[0006] The lower housing has first rollers on both sides of the middle section below it, and the upper housing has a handle hinged to the rear end. When the handle is rotated to the rear, the front side of the cleaning disc is raised with the first rollers as the central axis.

[0007] In one embodiment, the upper housing is further provided with a storage groove, and the handle is hinged to the rear side of the storage groove. The storage groove is used to store the handle when it rotates forward. The handle is also provided with a torsion spring at the hinge point. When the handle rotates backward, the torsion spring is used to finely adjust the position of the cleaning disc in accordance with the gravity of the entire device.

[0008] In one embodiment, a hook-shaped winding hook is rotatably connected to the handle near the rear side of the upper housing, and a switch to prevent misoperation is provided on the top side of the handle. The upper housing is provided with a control knob and a fuse for controlling the adsorption device and the driving device, and the switch is electrically connected to the control knob and the fuse.

[0009] In one embodiment, the driving device includes a driving wheel and a driven wheel linked by a belt. An adjusting plate is provided below the mounting plate.

[0023] 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.

[0024] like Figures 1-5 As shown, a hard surface cleaning device of the present invention includes a housing 1, which includes an upper housing 11 and a lower housing 12 that are detachably connected, and an mounting plate 13 is formed between the upper housing 11 and the lower housing 12.

[0025] The lower housing 12 has a collection box 2 located at the rear side below the mounting plate 13. The front side of the lower housing 12 is detachably fitted with a movable baffle 3 that can move up and down. A cleaning disc 4 is rotatably connected within the space enclosed by the movable baffle 3, and the collection box 2 is connected to the space enclosed by the movable baffle 3. An adsorption device 5 and a driving device 6 are respectively located near the rear side of the mounting plate 13. The adsorption device 5 is connected to the collection box 2, and the driving device 6 is linked to the cleaning disc 4.

[0026] The lower housing 12 has first rollers 7 on both sides of the middle part below it, and the upper housing 11 has a handle 9 hinged to the rear end. When the handle 9 is rotated to the rear, the front side of the cleaning disc 4 is raised with the first rollers 7 as the central axis.

[0027] This utility model has a compact structure, integrating cleaning, adsorption, and collection. Firstly, by using threaded connections to replace and install different cleaning discs 4, it allows for surface cleaning work such as grinding, polishing, and scrubbing. At this time, the adsorption device 5 and the collection box 2 directly connect to the cleaning space to adsorb dust. The adaptability of the movable baffle 3, which covers the cleaning space when the cleaning disc 4 rotates, prevents dust and wastewater from splashing, greatly improving the quality of the working environment. Furthermore, the entire device uses the mounting plate 13 as the main connecting part, resulting in a more reasonable overall force design. The adsorption device 5 and the drive device 6, which have greater weight, are mainly concentrated at the first roller 7. In addition to utilizing… In addition to the normal horizontal grinding and polishing of the cleaning disc 4, supported by the first roller 7, the user can also change the angle of holding the device by pressing down the handle 9 with the rotation axis of the first roller 7 as the center. This slightly tilts the front of the cleaning disc 4, making it suitable for cleaning surfaces with a certain slope. In actual use, this allows for convenient special usage methods and control, preventing the edges of the cleaning disc 4 and the housing from directly contacting the slope during movement. Furthermore, due to the setting of the movable baffle 3 and its range of vertical movement, it can cover the cleaning space in different situations to prevent dust from splashing, resulting in higher practicality and cleaning coverage.

[0028] In one embodiment, the upper housing 11 is further provided with a storage groove 16, and the handle 9 is hinged to the rear side of the storage groove 16. The storage groove 16 is used to store the handle 9 when it rotates forward. A torsion spring 10 is also provided at the hinge of the handle 9. When the handle 9 rotates backward, the torsion spring 10 is used to adjust the position of the cleaning disc 4 using the gravity of the entire device. The hinge between the handle 9 and the upper housing 11 allows it to rotate freely. When the user rotates the handle 9 forward, as... Figure 2 As shown, it can be folded for storage; when handle 9 is perpendicular to each other, it is as shown. Figure 1 As shown, this represents the horizontal grinding, polishing, and cleaning states; while when handle 9 continues to rotate backward, as... Figure 3 As shown, the device is flat overall. When the handle 9 is pressed down to the rear, the torsion spring 10 resists the hard structure of the upper housing 11, which in turn causes the front of the cleaning disc 4 to tilt upward. When it is close to some slopes, the front of the cleaning disc 4 tilts up more easily to adapt to the slope, making it easy to clean without damaging the housing. Furthermore, the movable baffle 3 mentioned above maintains the cleaning space at the cleaning disc 4, which facilitates the adsorption device 5 and the collection box 2 to adsorb dust.

[0029] In addition, a hook-shaped winding hook 91 is rotatably connected to the handle 9 near the rear side of the upper housing 11. This hook has a locking button. When the hook-shaped structure of the winding hook 91 is downward, it can be used to wind the wire around the top of the handle 9 for storage. Rotating the winding hook 91 to either side allows the wire to be quickly removed for power connection. A switch 92 to prevent accidental operation is also provided on the top side of the handle 9. The upper housing 11 has a control knob 17 and a fuse 18 for controlling the adsorption device 5 and the drive device 6. The switch 92 is electrically connected to the control knob 17 and the fuse 18. The user can control the operation of the device through the control knob 17, while the fuse 18 ensures timely power disconnection in case of short circuits or other situations. The switch 92 on the top side of the handle 9 is designed to prevent accidental operation; the device will only operate normally after the user holds the handle 9 and turns on the switch 92.

[0030] Furthermore, the drive device 6 includes a driving wheel 61 and a driven wheel 62 linked by a belt. An adjusting plate 63 is provided below the mounting plate 13. The driven wheel 62 is rotatably connected to the lower part of the adjusting plate 63. A screw 64 is threadedly connected to the rear side of the adjusting plate 63, and one end of the screw 64 is rotatably connected to the mounting plate 13. A positioning element 65 is also fixed on the mounting plate 13. Elongated mounting holes 66 are respectively opened at the four corners of the adjusting plate 63. The adjusting plate 63 is detachably connected to the positioning element 65 by screws passing through the mounting holes 66. The drive device 6 uses a belt pulley to drive the rotation of the cleaning disc 4 to achieve cleaning. Its motor and other components are concentrated at the first roller 7. The front and rear positions of the cleaning disc 4 can be adjusted via the adjusting plate 63 according to actual needs to adjust its cleaning position and degree. Specifically, the driven wheel 62 is rotatably connected to the adjusting plate 63, and the adjusting plate 63 can be adjusted to the front and back position by rotating the screw 64. Then, by inserting screws through the mounting holes 66 on the adjusting plate 63 and connecting them to the positioning member 65 on the mounting plate 13 for locking, the cleaning disc 4 can be adjusted to the appropriate position to cooperate with cleaning.

[0031] Specifically, the movable baffle 3 has a groove on its inner side, and a protruding edge 14 that matches the groove is provided on the front edge of the lower housing 12, with the width of the groove being greater than the width of the protruding edge 14. After the movable baffle 3 is fitted onto the front of the lower housing 12, the groove fits the protruding edge 14, thereby limiting the movable baffle 3 with the protruding edge 14, allowing the movable baffle 3 to have a certain range of vertical movement, but without detaching from the lower housing 12. In this way, when the cleaning disc 4 rotates for cleaning, especially on uneven ground, the movable baffle 3 can use its gravity to keep it wrapped around the outside of the cleaning disc 4, thus preventing dust and other particles from flying. The collection box 2 and the movable baffle 3 are detachably connected by a communicating air guide duct 31. A notch is left on the upper edge of the rear side of the movable baffle 3 near the air guide duct 31, and a fixed baffle 32 extends from the lower edge of the air guide duct 31 to cover the notch. Due to the vertical movement range of the movable baffle 3, a notch needs to be left at the upper edge of the movable baffle 3 near the first roller 7 to correspond to the position of the air guide duct 31 that connects the collection box 2 to the cleaning space. The air guide duct 31 can be disassembled and assembled as needed, and the fixed baffle 31 extending from the air guide duct 31 can cover the above-mentioned notch, thereby preventing dust from flying in this area and ensuring that the suction of the adsorption device 5 can introduce the dust into the collection box 2.

[0032] In addition, second rollers 8 are respectively provided on both sides of the rear end below the lower housing 12. The diameter of the second rollers 8 is smaller and their position above the ground is higher than that of the first rollers 7. The first rollers 7 are larger and serve as the main support structure when the equipment is cleaning horizontally. The second rollers 8 are smaller and only need to be set at a certain height at the rear so that the cleaning tray 4 can contact the ground when stored and transported. They also work with the first rollers 7 to support the center of gravity of the equipment for easy movement. When the entire equipment is stored, support feet 15 are provided on both sides of the rear end of the upper housing 11. That is, the second rollers 8 and the support feet 15 can be used to completely stand the entire equipment upright, which makes it easy to replace different cleaning trays 4 or store them.
