Description

Technical Field

[0001] The utility model relates to the technical field of floor washing machines, in particular to a floor washing machine with height adjustment through a gear box. Background Technique

[0002] For a floor washing machine with height adjustment through a gear box, its working principle mainly depends on a precise gear box system. This system allows users to easily adjust the height of the brush or mop of the floor washing machine according to different ground conditions and cleaning requirements.

[0003] The existing Chinese patent (Publication No.: CN210697498U) proposes a floor washing machine with adjustable floor washing brush height, including a moving vehicle. A handle is fixedly connected to the upper left end of the moving vehicle. A garbage collection box is fixedly connected to the upper end inside the moving vehicle. A mounting plate is fixedly connected to the lower left end of the moving vehicle. A left motor is fixedly connected to the lower end of the mounting plate. The driving end of the left motor is rotationally connected to a left adjusting rod. A water tank is fixedly connected to the lower end inside the moving vehicle. A gear box is fixedly connected to the lower right end inside the moving vehicle. A right motor is installed at the upper end of the gear box. A right adjusting rod is installed at the lower end of the gear box. A right brush is fixedly connected to the lower end of the right adjusting rod.

[0004] The above technical solution can also freely adjust the height of the left brush at the lower end of the left adjusting rod and the right brush, and thus can clean floors of different heights, reducing the limitations of the floor washing machine and making the floor cleaning cleaner.

[0005] However, the gears in the gear box may be worn after long-term use, and may produce relatively large noises due to component looseness or wear, affecting the service life and effect, resulting in inaccurate operation or malfunction of the equipment. Since the internal structure of the gear box is complex, it is relatively difficult for users to repair it by themselves once a malfunction occurs. The above device does not have targeted improvement for this, so we propose a floor washing machine with height adjustment through a gear box. Content of the Utility Model

A detector 7 is provided at the top of the gearbox 2. By setting the detector 7, when the gears inside the gearbox 2 are aged and worn, a louder noise than usual will be generated. At this time, the detector 7 will send a command to the second motor, thereby driving the lead screw 52 to rotate. The rotation of the lead screw 52 drives the slider 53 to slide inside the slide rail 51. The slider 53 drives the extrusion block 54 to move towards the lubricating oil dropper 55, thereby extruding the lubricating oil to the meshing part between the gears for lubrication to prevent excessive wear of the gears;

[0036] Furthermore, as Figure 2 shown: The adjustment component 4 includes a first motor 41. The output end of the first motor 41 is fixedly connected to a first fixed shaft 42. A transmission gear 43 is provided on the first fixed shaft 42. Second fixed shafts 44 are provided on both sides of the gearbox 2 close to the transmission gear 43. A driven gear 45 is provided on the second fixed shaft 44. The driven gear 45 is meshed and connected to the transmission gear 43. A screw 46 is threadedly connected inside the second fixed shaft 44. Universal wheels 10 are provided at the bottom of the body 1. There are two lubricating oil droppers 55, and the two lubricating oil droppers 55 are respectively located at the top of the meshing part between the driven gear 45 and the transmission gear 43. By setting the adjustment component 4, when the first motor 41 is turned on, it drives the first fixed shaft 42 to rotate. The first fixed shaft 42 drives the transmission gear 43 to rotate. The transmission gear 43 drives the driven gear 45 to rotate. The driven gear 45 drives the second fixed shaft 44 to rotate. The second fixed shaft 44 drives the screw 46 to rotate up and down, thereby completing the adjustment;

[0037] In the above solution, there is also a situation where the ground is uneven. The brush disk 64 can also be automatically adjusted according to the situation, as Figure 4 shown: A cleaning component 6 is provided at the bottom of the screw 46.

A conduit 32 is fixedly connected to the bottom of the water tank 31. A water pump 33 is provided on the conduit 32. By providing the spraying component 3, the ground is sprayed to improve the cleaning effect.

[0040] Working principle: As Figure 1 - Figure 4 shown, by providing the detector 7, when the gears inside the gearbox 2 are aged and worn, a greater noise will be generated than usual. At this time, the detector 7 will send a command to the second motor, thereby driving the lead screw 52 to rotate. The rotation of the lead screw 52 drives the slider 53 to slide within the slide rail 51. The slider 53 drives the extrusion block 54 to move towards the lubricating oil dropper 55 side, thereby extruding the lubricating oil dropper 55, and thus squeezing out the lubricating oil to the meshing part between the gears for lubrication to prevent excessive wear of the gears. By providing the adjusting component 4, the first motor 41 is turned on to drive the first fixed shaft 42 to rotate. The first fixed shaft 42 drives the transmission gear 43 to rotate. The transmission gear 43 drives the driven gear 45 to rotate. The driven gear 45 drives the second fixed shaft 44 to rotate. The second fixed shaft 44 drives the screw 46 to rotate and lift, thereby completing the adjustment. By providing the cleaning component 6, the ground is cleaned. By providing the universal ball 61 and the spring 63, it can be automatically adjusted according to the uneven road surface. By providing the lifting component 8, the height of the grip 9 can be adjusted to adjust a comfortable position according to different people's heights. By providing the spraying component 3, the ground is sprayed to improve the cleaning effect.
