TRANSVERSING MOPPING MECHANISM

Description

TECHNICAL FIELD OF THE INVENTION

The present invention relates to the technical field of cleaning devices, and in particular to a transversing mopping mechanism.

BACKGROUND OF THE INVENTION

Mopping machines are a kind of devices specially used for cleaning the floor. At present, there are many kinds of mopping machines in the market. One kind of mopping machines is hand-held mopping machines, such as CN201910058458.5, which have higher cleaning power than mops, but are less intelligent. Thus, another kind of intelligent mopping machines has been proposed, which generally mop the floor by using the rotating mopping cloth, such as CN202110709981.7, where the mopping cloth is generally arranged inside the chassis of the mopping machine and thus is difficult to completely clean the corners of the floor, so that the mopping cloth will be attached with dirt after a period of time and needs to be manually detached and cleaned, resulting in inconvenient use and more water consumption in washing the mopping cloth.

Therefore, it is urgent to innovate the operating principle and matched structure of the mopping machine to obtain a mopping machine capable of cleaning corners, automatically cleaning the mopping cloth and saving more water.

As shown in FIG. 1, the transversing mopping mechanism of the present utility model includes a first holder 11, a second holder 12, roller wheel holders 13, a moving component and a mopping cloth strap 4. The moving component is roller wheels 14. There are total four roller wheel holders 13, and a roller wheel 14 is provided below each roller wheel holder 13.

The mopping cloth strap 4 is removed to present the internal structure of the transversing mopping mechanism of the present utility model, as shown in FIG. 2, including a power system 2, a roller shaft component and a cleaning component. The power system 2 is composed of a battery and a motor and provides power to the moving component and the roller shaft component. The roller shaft component includes a first transmission roller shaft 31, a second transmission roller shaft 32, a third transmission roller shaft 33, a fourth transmission roller shaft 34, a water squeezing roller shaft 35, roller shaft nuts 36, a first transmission wheel 371, a second transmission wheel 372 and a transmission belt 373. The power system 2 drives the second transmission wheel 372 to rotate and drives the first transmission wheel 371 to rotate through the transmission belt 373. The first transmission wheel 371 is fixed to the first transmission roller shaft 31 so as to drive the first transmission roller shaft 31 to rotate. The second transmission roller shaft 32, the third transmission roller shaft 33 and the fourth transmission roller shaft 34 are all provided with the roller shaft nuts 36, so that they are mounted on the frame and can rotate about their axes. Two guide grooves are formed on each transmission roller shaft. By taking the fourth transmission roller shaft 34 as an example, a first guide groove 341 and a second guide groove 342 are formed on the fourth transmission roller shaft 34.

The cleaning component includes a first limiting rod 511, a second limiting rod 512, a water collecting tank 52, a filter mesh 53, a hairbrush 54, a water pump 55, a first spray pipe 561, a second spray pipe 562 and a liquid level meter 57. The water collecting tank 52 is arranged inside the transversing mopping machine, the filter mesh 53 is arranged in the water collecting tank 52, and the first limiting rod 511, the second limiting rod 512 and the hairbrush 54 are arranged above the filter mesh 53. The bottom of the hairbrush 54 is a hairbrush head 541. The water pump 55 has a water inlet and a water outlet. The water inlet is arranged on the bottom of the water collecting tank 52, while the water outlet is connected to the first spray pipe 561 and the second spray pipe 562. There are spray ports below the first spray pipe 561 and the second spray pipe 562, which can spray water downward. The filter mesh 53 divides the water collecting tank 52 into upper and lower zones. The zone above the filter mesh 53 is called a first filter zone, while the zone below the filter mesh 53 is called a second filter zone. A sewage discharge port is formed on the bottom of the first filter zone, and discharges the dirt on the filter mesh 53 when it is opened.

As shown in FIG. 3, a first guide plate 171 and a second guide plate 172 are provided on both sides of the bottom of the frame, respectively. One side of each of the first guide plate 171 and the second guide plate 172 is close to the third transmission roller shaft 33, while the other side thereof is close to the fourth transmission roller shaft 34. Both the first guide plate 171 and the second guide plate 172 are connected to the first fixed plate 181 and the second fixed plate 182 for fixation and supporting. The first fixed plate 181 is arranged below the second transmission roller shaft 32, and the second fixed plate 182 is arranged below the first transmission roller shaft 31 and the water squeezing roller shaft 35. The first transmission roller shaft 31, the second transmission roller shaft 32, the third transmission roller shaft 33 and the fourth transmission roller shaft 34 are arranged on the inner side of the mopping cloth strap 4, while the water squeezing roller shaft 35 is arranged on the outer side of the mopping cloth strap 4. The first transmission roller shaft 31 and the water squeezing roller shaft 35 clamp the mopping cloth strap 4.

As shown in FIG. 4, the mopping cloth strap 4 is a ring-shaped cloth strip. A first guide strip 42 and a second guide strip 43 are arranged on the inner side of the mopping cloth strap 4, and a first guide edge strip 41 and a second guide edge strip 44 are arranged on the side face thereof. The guide strips are matched with the guide grooves, and the guide edge strips correspond to the side faces of the transmission roller shafts. The guide edge strips also correspond to the guide plates. By taking the fourth transmission roller shaft 34 as an example, the first guide strip 42 is matched with the second guide groove 342, the second guide strip 43 is matched with the first guide groove 341, and the first guide edge strip 41 and the second guide edge strip 44 clamp both sides of the fourth transmission roller shaft 34.

In combination with FIGS. 3 and 4, the first guide plate 171 is clamped by the first guide edge strip 41 and the first guide strip 42, and the second guide plate 172 is clamped by the second guide edge strip 44 and the second guide strip 43, so that the mopping cloth strap 4 is not dislocated, thus achieving the guiding effect.

In combination with FIGS. 1-4, the rear surface of the mopping cloth strap 4 wraps the first transmission roller shaft 31, the second transmission roller shaft 32, the third transmission roller shaft 33 and the fourth transmission roller shaft 34, while the top of the front surface is pressed down by the first limiting rod 511 and the second limiting rod 512. The first spray pipe 561 and the second spray pipe 562 are arranged above the mopping cloth strap 4.

As shown in FIG. 5, a surface cover 16 is fixed on the top by six bolts 15. The top of the liquid level meter 57 is fixed on the surface cover 16, while the bottom thereof is arranged on the bottom of the water collecting tank 52.

The operating principle of the transversing mopping mechanism of the present utility model is given below.

As shown in FIG. 6, the arrow a indicates the transmission direction of the mopping cloth strap, and the arrow b indicates the traveling direction of the mopping mechanism. The two directions are perpendicular to each other, so it is called "transversing". The power system 2 drives the roller wheels 14 to rotate to advance the mopping machine, so as to push the moping cloth strap 4 on the bottom of the mopping mechanism to rub against the floor, thus realizing the mopping function. The left or right side of the traveling direction can be close to the included angle between the wall and the floor so as to clean corners. Since the mopping cloth strap 4 is provided with guide strips matched with the guide grooves on the transmission roller shafts and also provided with guide edge strips to clamp both sides of the transmission roller shafts and the guide plates, the mopping cloth strap 4 will not be dislocated during normal operation, and can be restored in place even when being dislocated in special cases.

After the mopping mechanism travels for a certain period of time, the mopping cloth strap 4 is dirty, and the power system 2 does not drive the roller wheels 14 and instead drives the first transmission roller shaft 31 to rotate. The mopping cloth strap 4 is transmitted in the direction of arrow a, and the dirty part of the mopping cloth strap 4 enters the water collecting tank 52 and is then cleaned by the cleaning component. Meanwhile, the part of the mopping cloth strap originally in the water collecting tank 52 has been cleaned and transmitted to the bottom for continuous mopping. In the above process, the roller wheels 14 are automatically locked to prevent the side slipping of the mopping mechanism.

The cleaning process of the mopping cloth strap is given below. Firstly, the dirty part of the mopping cloth strap 4 is pressed down after passing through the second limiting rod 512 to come into contact with the hairbrush 541. Along with the transmission, the hairbrush head 541 brushes the surface of the mopping cloth strap 4, and mopping cloth strap 4 then passes through the first limiting rod 511. The power system 2 drives the water pump 55 to operate, and water is sprayed from the first spray pipe 561 and the second spray pipe 562 to wash the mopping cloth strap 4 for two times. The dirty water flows downward and is filtered by the filter mesh 53. The dirt remains on the filter mesh 53, and the water enters the bottom of the water collecting tank 52. Finally, the mopping cloth strap 4 is clamped by the first transmission roller shaft 31 and the water squeezing roller shaft 35, so that the excessive water is squeezed out to enter the bottom of the water collecting tank 52. So far, the mopping cloth strap 4 has been cleaned. The water on the bottom of the water collecting tank 52 can be recycled. The liquid level meter 57 can detect the liquid level in the water collecting tank 52. When the water level is low, the operation is suspended, and an external water pipe is connected for adding water.
