Abstract
Description
Technical Field
[0001] This utility model relates to the field of interior decoration technology, and in particular to a floor cleaning device for interior decoration. Background Technology
[0002] Grout sealing is a common renovation technique. Its main purpose is to seal the gaps between floorboards to prevent bacterial growth and leaks. Nowadays, grout sealing is no longer just about preventing bacteria and leaks; people are also pursuing its aesthetics and practicality. Nowadays, when a house changes owners or the room layout is altered, the floorboards inevitably need to be renovated. This requires removing the hardened grout from the floorboards to facilitate the next step of removing the floorboards or replacing them with grout of a different color.
[0003] Patent publication number CN110948356A discloses a reciprocating floor grout cleaning device, including a tubular handle. A micro-motor is installed at one end of the handle, and the rotating shaft of the micro-motor extends out of the handle and is fixedly connected to an eccentric grinding wheel. A steel brush is also installed on the outer circumference of the eccentric grinding wheel. A protective unit is also provided on the handle, including a torsion spring. One end of the torsion spring is fixed to the end of the handle connected to the eccentric grinding wheel, and the other end of the torsion spring is connected to a protective cover. This invention, a reciprocating floor grout cleaning device, uses a protective cover, which facilitates observation of the grinding process while preventing personal injury. The use of an eccentric grinding wheel, compared to traditional grinding wheels which only have a grinding function, adds the abrasive effect of the steel brush. The distribution of the steel brushes ensures the balance of the eccentric grinding wheel, increasing the grout cleaning speed and demonstrating good practical value. However, although this device improves grout cleaning efficiency, it requires workers to hold it by hand and squat on the ground to clean the grouts. Furthermore, the cleaning process generates a large amount of dust, and the worker's close proximity to the cleaning device causes them to inhale a large amount of dust, potentially causing harm to their health.
[0004] Therefore, we urgently need a dust-collecting floor cleaning device for interior decoration. Utility Model Content

Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1
[0017] A floor grout cleaning device for interior decoration, such as Figures 1-3 As shown, the assembly includes a fixed base plate 1, a U-shaped plate 2, adjusting rods 3, grippers 31, knobs 4, support rods 5, an angle grinder 6, a vacuum cleaner 7, a pipe 71, a dust collection hood 8, auxiliary wheels 10, a handle 11, and V-shaped wheels 12. The upper left and right sides of the fixed base plate 1 are symmetrically connected to the U-shaped plates 2 by bolts. Adjusting rods 3 are provided at the front of each U-shaped plate 2. Grippers 31 are welded to the sides of the adjusting rods 3 that are close to each other. Knobs 4 are threaded onto each adjusting rod 3. Support rods 5 are rotatably connected to the middle of the fixed base plate 1 via bearing seats. The grippers 31 clamp the components together. An angle grinder 6 is fixed in place. The upper end of the support rod 5 is rotatably connected to the angle grinder 6 via a rotating shaft. A dust collection cover 8 is connected to the outside of the grinding blade of the angle grinder 6 via a rotating shaft. A vacuum cleaner 7 is bolted to the upper part of the fixed base plate 1. A pipe 71 is fixed to the vacuum cleaner 7. The tail end of the pipe 71 is connected to the dust collection cover 8. An auxiliary wheel 10 is installed at the rear of the fixed base plate 1. The surface of the auxiliary wheel 10 is provided with anti-slip texture. A handle 11 is welded to the rear of the fixed base plate 1. The handle 11 is retractable. A V-shaped wheel 12 is installed at the front of the fixed base plate 1. The V-shaped wheel 12 can fit with the floor seam.
[0018] Figure 1 and Figure 2 As shown, it also includes a drive motor 9. The drive motor 9 is threadedly mounted on the upper part of the fixed base plate 1. The output shaft of the drive motor 9 is connected to the rotating shaft of the left auxiliary wheel 10 through a coupling, so that the device can move on its own.
[0019] Working principle: When using this device, first place it in the desired location, then align the V-shaped wheel 12 with the floor seam, and ensure the grinding blade of the angle grinder 6 is aligned with the seam to be cleaned. To adjust the cleaning depth, first loosen the knob 4 from the adjusting rod 3, allowing the angle grinder 6 to rotate on the U-shaped plate 2. As the angle grinder 6 rotates, the adjusting rod 3 will also rotate. After adjusting the angle, tighten the knob 4 to re-secure the angle grinder 6. Then, start the device; the angle grinder 6 will begin cleaning. Connect a dust bag to the left end of the pipe 71. When the vacuum cleaner 7 is operating, the dust generated during cleaning will be collected. Dust is sucked into the dust collection hood 8 by the vacuum cleaner 7, then enters the vacuum cleaner 7 through the pipe 71, and is discharged into the dust collection bag from the left end of the pipe 71, thus achieving the dust collection effect. The output shaft of the drive motor 9 will rotate the auxiliary wheel 10. The anti-slip texture can prevent the device from slipping and deviating from the track. The V-shaped wheel 12 guides the device forward, so that the device can automatically perform dust cleaning. Pulling up the handle 11 can stretch the handle 11, and pressing down the handle 11 can compress the handle 11, which makes it easy for the user to move the device. After the work is completed, the device can be turned off and the dust collection bag can be removed and disposed of.
