Detailed Description

The utility model is described in further detail below with reference to fig. 1-11.

As shown in fig. 1, 2 and 8, a tracked scrubber of twin-roll construction comprises:

a handle 1;

the liquid storage bin 2 is used for storing cleaning liquid, and the cleaning liquid can be common clear water, water added with a cleaning agent or directly prepared finished cleaning liquid;

the cleaning device comprises a machine body 3, a cleaning component 4 and a liquid spraying part 5 are arranged in the machine body 3, the cleaning component 4 comprises a first roller body 6, a second roller body 7 and a cleaning part 8, the cleaning part 8 is of an annular structure, the cleaning part 8 is sleeved on the first roller body 6 and the second roller body 7, the first roller body 6 and the second roller body 7 are both positioned inside the annular structure of the cleaning part 8, the outer surface of the annular structure of the cleaning part 8 is a cleaning working surface, and a mutual transmission structure is formed among the first roller body 6, the second roller body 7 and the cleaning part 8; the liquid ejecting section 5 can eject the cleaning liquid onto the cleaning section 8 or the object to be cleaned; and

and the liquid flow channel is connected between the liquid storage bin 2 and the liquid spraying part 5.

The cleaning device is characterized by further comprising a suction channel 9 and a sewage bin 10, negative pressure can be formed in the suction channel 9 by using an exhaust fan, and water which is used for cleaning the ground enters the sewage bin 10 through the suction channel 9, so that sewage is recovered, moisture cannot be remained on an object to be cleaned, and the cleaning effect is guaranteed.

The utility model has the beneficial effects that the two roller bodies, the cleaning part 8 of the annular structure sleeved on the two roller bodies and the first roller body 6, the second roller body 7 and the cleaning part 8 form a mutual transmission structure, so that the first roller body 6, the second roller body 7 and the cleaning part 8 are all in a rotating state in a working state, and the cleaning part 8 in one surface area between the first roller body 6 and the second roller body 7 can be contacted with an object to be cleaned in the rotating process. Therefore, the traditional line contact of a single rolling brush is innovated into the surface contact of the utility model, and the cleaning efficiency is greatly improved.

Meanwhile, the cleaning device also comprises a water squeezing roller 25, wherein the water squeezing roller 25 is attached to the cleaning part of the annular structure. Taking fig. 11 as an example, if the cleaning part 8 rotates counterclockwise, the wringing roller 25 is located behind the liquid spraying part as much as possible, that is, after the floor is cleaned, a certain amount of sewage is adhered to the cleaning part, and the sewage is squeezed out by the wringing roller, the cleaning part is in a relatively water-deficient state, and the clean water on the liquid spraying part can be sprayed onto the cleaning part for the next round of cleaning operation. The wringing roller 25 can also be disposed on the non-working area of the cleaning portion 8, as long as the wringing roller can be brought close to the cleaning portion, thereby realizing a simple pressing function and also bringing the cleaning portion into a more tightened state.

Meanwhile, the traditional rolling brush is manufactured in a mode of flocking on the cylindrical roller, or the flocking is directly connected to the rolling brush in a mode of strong adhesion. This kind of mode just can guarantee that fine hair and round brush are complete integral type, guarantees clean effect, and traditional round brush does not have the scheme of any set of round brush cover of taking fine hair because can skid each other like this to influence clean effect. Although the cleaning effect is ensured, the fluff of the integral rolling brush is easy to wear. When the traditional rolling brush is worn, the whole rolling brush can only be replaced, the replacement cost is very high, and the resource saving is not facilitated. However, in the double-roller structure provided by the utility model, the cleaning part 8 is sleeved on the first roller 6 and the second roller 7, so that a detachable structure is formed, and when the cleaning part 8 is damaged and the cleaning effect is poor, the cleaning part 8 with the annular structure can be independently replaced, so that the cleaning part 8 with the annular structure is used as a consumable, the viscosity between a manufacturer and a user is kept, and the repurchase rate of the cleaning part 8 with the annular structure for the user is increased. Meanwhile, cleaning parts 8 of different models can be provided to allow users to selectively purchase. Different types of cleaning parts 8 can be provided with fluff with different thicknesses, for example, the cleaning parts 8 with the fluff can be fine, the cleaning parts 8 with the fluff can also be coarse, and when a user mainly cleans a coarse ground (such as a cement ground), the cleaning parts 8 with the fluff can be selected as much as possible, so that the cleaning parts 8 have longer service life. When the user mainly cleans a relatively flat ground (e.g., a wooden floor), the cleaning portion 8 having fine hairs may be selected as much as possible.

The cleaning part 8 in the utility model can be cloth with fluff on one surface, and the surface with fluff is a cleaning working surface. The two ends of the cloth are sewn together to form a loop, or the two ends are connected by a hook. Or as shown in fig. 9, the two ends of the cloth are connected by a zipper, and the zipper can adopt an inner-pulling mode, that is, the zipper head 12 is positioned inside the annular structure, so as to ensure that the outer surface of the whole annular structure is flat, thereby protecting the cleaning effect. When the zipper head 12 located inside the annular structure is in a working state, the zipper head may collide with the two roller bodies to affect rotation and possibly generate abnormal sound, the groove 11 can be formed in the first roller body 6 and the second roller body 7 creatively, the zipper head 12 continuously winds on a loop line in the whole rotation process of the cleaning portion 8, and only the groove 11 is just required to be located on the loop line, which is equivalent to the situation that the zipper head 12 just falls into the groove 11 when moving to the positions of the first roller body 6 and the second roller body 7, so that the mutual collision with the roller bodies is prevented, the rotation smoothness of the cleaning portion 8 is ensured, and a good cleaning effect is ensured.

Meanwhile, the cleaning part 8 can also be an annular belt, the annular belt can be directly formed by integral injection molding or connected with two ends in a hot melting joint mode, and fluff is planted or adhered on the outer surface of the annular belt to form a cleaning working surface. The inner surface of the endless belt is flat or toothed. If the inner surface of the endless belt is toothed, the respective first roller body and second roller body also need to be toothed, so that a good transmission is ensured.

The first roller body 6, the second roller body 7 and the cleaning part 8 form a power source of a mutual transmission structure, and the first roller body 6 can be a driving roller; or the second roller body 7 is a driving roller; or as shown in fig. 7, a separate power roller 13 is attached to the cleaning section 8. That is, for example, a motor may be connected to the first roller 6 directly or indirectly, and then the first roller 6, the second roller 7 and the cleaning portion 8 are driven to rotate simultaneously, so that the cleaning portion 8 in one surface area between the first roller 6 and the second roller 7 can contact and move with the object to be cleaned, thereby achieving the cleaning effect. Of course, the second roller body 7 may be driven by the motor first. Alternatively, as shown in fig. 7, a single power roller 13 may be driven by a motor, and the cleaning unit 8 may be rotated by the power roller 13.

The mutual transmission among the first roller body 6, the second roller body 7 and the cleaning part 8 is realized mainly by friction force. In order to better prevent the cleaning portion 8 from slipping with the first roller body 6 and the second roller body 7, as shown in fig. 3, anti-slip patterns 14 may be provided on the surface of the first roller body 6 and/or the second roller body 7, the anti-slip patterns 14 on the first roller body 6 and/or the second roller body 7 may be plain, twill or cross patterns, or the anti-slip patterns 14 may be provided on the inner surface of the cleaning portion 8, and the anti-slip patterns 14 on the cleaning portion 8 may be plain, twill or cross patterns.

The most easily conceivable one is a plain weave, that is, the first roller body 6 and/or the second roller body 7 may be selectively provided with anti-slip threads 14 parallel to the length direction thereof, so as to increase the friction force between the cleaning portion 8 and the first roller body 6 and the second roller body 7 and ensure a good transmission effect.

However, the cleaning part 8 is easy to shift laterally during the adjustment of rotation, so the utility model creatively provides the anti-skid veins 14 in the form of twill veins. The twill can be set to the splayed line as far as possible, namely anti-skidding line 14 on first roll body 6 and the second roll body 7 divide into two parts about, and the symmetry sets up and forms a splayed shape, like this if the cleaning part 8 that cloth was made, in the middle of the pivoted process, the twill of splayed will be continuous carries out the exhibition flat action with cleaning part 8 to can prevent that cleaning part 8 from to certain side skew, also can prevent that cleaning part 8 itself from taking place the fold.

If the cross-hatching is provided, the problem that the cleaning portion 8 slips or is shifted to one side can be prevented more effectively.

Meanwhile, as shown in fig. 3 and 4, in order to solve the problem of the deviation of the cleaning part 8, the limiting steps 15 may be further disposed at two ends of the first roller body 6 and the second roller body 7, a shallow groove body is just formed on the surfaces of the limiting steps 15 and the first roller body 6 or the second roller body 7, and the cleaning part 8 is just embedded in the groove body, so that the cleaning part 8 is prevented from deviating in the rotating process.

Similarly, the inner surface of the cleaning part 8 may be provided with the anti-slip pattern 14, and the anti-slip pattern 14 on the cleaning part 8 may be a plain pattern, a twill pattern, or a cross pattern. The problems of slipping and wrinkling are solved.

As shown in fig. 6, conventional floor washers typically have larger rollers to ensure better and greater contact between the rollers and the floor. However, this causes a problem that when the wall corner is cleaned, the roll brush, the floor and the wall surface form a triangle because the roll brush has a larger diameter, the bottom side of the triangle (the length of the bottom side is equal to the radius of the roll brush) is a cleaning blind area 16, and the roll brush cannot be cleaned, so that a dead angle is left. The larger the brush diameter, the larger the cleaning dead zone 16.

As shown in fig. 5, the diameter of the first roller 6 is set smaller than that of the second roller 7, the first roller 6 is located at the front end of the machine body 3, and the second roller 7 is located behind the first roller 6. Meanwhile, the lowest point of the first roller body 6 and the lowest point of the second roller body 7 are ensured to be on the same horizontal plane. That is, it is ensured that the cleaning portion 8 of the one surface area between the first roller body 6 and the second roller body 7 can still be brought into effective contact with the object to be cleaned during the rotation. The smaller the diameter of the first roller body 6, the smaller the corresponding blind cleaning zone 16. Simultaneously because first roll body 6 diameter is less and be located the front end, so whole organism has a little tip of protrusion forward, and this first roll body 6 of protrusion can stretch into some regions that highly is less to carry out cleaning work, places such as similar bed bottom, cabinet foot.

The mutual transmission among the first roller body 6, the second roller body 7 and the cleaning part 8 is realized by friction force, and the cleaning part 8 with an annular structure can be a belt with teeth, namely, the inner surface of the cleaning part 8 is provided with teeth, and the corresponding first roller body 6 and the second roller body 7 are also provided with teeth. The corresponding transmission can be realized through the tooth matching among the three components. The transmission of the toothed belt is more stable.

As shown in fig. 3 and 4, in the present invention, a side pull cover plate 17 may be alternatively provided on the machine body 3, one end of each of the first roller 6 and the second roller 7 is provided on the side pull cover plate 17, the other end of each of the first roller 6 and the second roller 7 is detachably connected to the machine body 3, and the cleaning portion 8 having an annular structure may be inserted into or removed from the other end of each of the first roller 6 and the second roller 7. This allows the cleaning portion 8 to be removed or replaced.

However, in practical use, the cleaning part 8 with a ring structure is easy to install and disassemble. Because the cleaning part 8 needs to work effectively, the cleaning part 8 and the first roller body 6 and the second roller body 7 need to be kept in a relatively tight state, and a large friction force is required to prevent slipping. I.e. a relatively large distance between the first roller body 6 and the second roller body 7 is required. But if the distance between the two is too large, the cleaning part 8 can become very inconvenient to mount and dismount.

In order to solve the above problems, the present invention provides a solution:

the cleaning part 8 can be made of elastic material, for example, a cloth with elasticity can be selected, so that the cleaning part can be quickly mounted and dismounted, and can keep a large friction force with each other.

Alternatively, as shown in fig. 10, at least one of the first roller body 6 and the second roller body 7 may be movably connected to the side draw-out cover 17, and the distance between the first roller body 6 and the second roller body 7 may be adjusted to allow the cleaning portion 8 having an annular structure to be attached and detached. As shown in fig. 4 and 8, a first connecting seat 18 and a second connecting seat 19 are provided on the body 3 at positions opposite to the other ends of the first roller body 6 and the second roller body 7. The first roller body 6 is connected to a first connecting base 18, the connection of which has a guide ramp 20. The second roller 7 is connected to the second connecting seat 19, and the connecting position thereof also has a guiding slope 20.

As shown in fig. 10, in the present embodiment, the first roller 6 is movably connected to the side pull-out cover plate 17, and the second roller 7 is fixedly connected to the side pull-out cover plate 17, when the cleaning portion 8 needs to be installed, the first roller 6 can be moved to be slightly close to the second roller 7, so that the opening formed between the first roller 6 and the second roller 7 is reduced, and the cleaning portion 8 with an annular structure can be conveniently installed or removed.

In fact, relatively speaking, have one in the middle of first roll body 6 and the second roll body 7 as far as possible to be fixed connection on the apron 17 is taken out to the side to the second roll body 7 is suitable for fixed connection, can guarantee like this that the side is taken out and forms a relatively stable structure between apron 17 and the first roll body 6, convenience of customers takes out and holds. Meanwhile, the second connecting seat 19 may be arranged longer in the horizontal direction, and the first connecting seat 18 may be arranged shorter than the second connecting seat 19, closer to the side of the side draw-out cover plate 17. Like this, this stable structure is when carrying out the integral erection, just can utilize the length difference between first connecting seat 18 and the second connecting seat 19, let second roll body 7 and second connecting seat 19 aim at in advance and be connected, then utilize the side to take out the relatively stable structure that forms between apron 17 and the first roll body 6 and pull by power a little backward, so that let first roll body 6 and second roll body 7 resume a parallel state, second roll body 7 just can reach the position of more aiming at relatively with second connecting seat 19 like this, again with side take out apron 17, first roll body 6 and second roll body 7 are whole to the direction propulsion of two connecting seats, can realize that cleaning assembly 4 installs on organism 3.

If the first roller body 6 and the second roller body 7 are movably connected, a slight sloshing feeling is generated.

The direction slope 20 of the junction of two roll bodys and two connecting seats can be a little chamfer, perhaps two connecting seats all set up conical structure or frustum structure, as long as two roll bodys have a little slope with the position that two connecting seats are connected can to form a direction slope 20, thereby make things convenient for the roll body to be connected with the location of connecting seat.

Meanwhile, the first roller body 6 and the second roller body 7 are required to be maintained in a parallel state because of the final installation. However, initially, the first roller body 6 and the second roller body 7 are not normally in a standard parallel state, and the guiding ramp 20 ensures that the two roller bodies in the non-parallel state are spread to be in a standard parallel state, and finally the cleaning assembly 4 is mounted in place.

As shown in fig. 2 and 3, the body 3 is further provided with a tension pulley 21, and the tension pulley 21 is attached to the cleaning section 8 having an annular structure. Usually, the front upper side of the machine body 3 is provided with a cover 22, an accommodating groove 23 can be formed on the inner wall of the cover 22, a spring 24 is arranged on the accommodating groove 23, the tension wheel 21 is arranged on the spring 24, and the tension force of the tension wheel 21 is realized by the elastic force of the spring 24.

The foregoing disclosure discloses only some embodiments of the utility model. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept herein, and it is intended to cover all such modifications and variations as fall within the scope of the utility model.
