The bottom of the robot is generally provided with a horizontally arranged rotating disc, cleaning cloth is arranged on the rotating disc, and then the bottom surface is cleaned through the rotation of the rotating disc. The product has the defects that only dust scrubbing can be carried out, and the product has no collecting effect on non-dust dirt such as large-particle dirt, packaging bags and the like; meanwhile, the cleaning cloth of the device is very troublesome to replace, which causes inconvenience to users.

Some novel high-end cleaning robots can also simultaneously design functional modules of a sweeper and a floor wiper, so that dirt collection and ground wiping can be simultaneously carried out. However, the device needs to design two sets of independent cleaning mechanisms, so that the problems of large volume and high production cost exist. Meanwhile, the products have some disadvantages of the two products, so that the equipment is usually sold as a commercial product for cleaning the bottom surface of large places such as markets, enterprises and factories and is not suitable for household use.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

The present embodiment provides a roller type cleaning robot, as shown in fig. 1 and 2, which includes a body 1 capable of walking, and a trash can 3 and at least one set of cleaning devices are disposed in the body 1. As shown in the drawings, the cleaning robot provided in the present embodiment has a main body 1 that can walk on the floor as in all conventional floor sweepers. A map, a radar, a controller and the like can be further arranged in the machine body 1, so that automatic path planning and obstacle avoidance functions are achieved, and the cleaning robot can achieve full-automatic cleaning without depending on people. In other schemes, the machine body 1 can also be manually controlled to walk in a hand-held or other modes, so as to realize semi-automatic cleaning.

The design of the cleaning robot of the present embodiment differs from most existing designs mainly in the trash can 3 and the sweeping mechanism. As shown in fig. 3, the dustbin 3 is located at the front side of the cleaning device with reference to the traveling direction of the body 1.

The cleaning devices are shown in fig. 4, and each set of cleaning devices includes a bracket 21, a winding roller 22, a driving mechanism 23, and a replaceable cleaning towel 24. The winding roller 22 is mounted on the bracket 21, and the elastic layer 220 is arranged on the surface of the winding roller 22 at intervals. The surface of the winding roller 22 is also provided with a fastener 221 for fixing the cleaning cloth 24. The cleaning sheet 24 is replaceably wound on the surface of the winding roll 22 by a fastening member 221. The winding roller 22 is horizontally disposed and perpendicular to the traveling direction of the body 1. The driving device is used for driving the winding roller 22 to rotate; the winding roller 22 is in contact with and pressed against the ground in the operating state.

The garbage can 3 is a shell with a containing cavity, and a gap for dirt to pass through is formed between the bottom surface of the garbage can 3 and the ground to be cleaned; the wall of the garbage can 3 close to the cleaning device 2 is arc-shaped along with the winding drum. The winding roller 22 winds the cleaning towel 24 and is close to but not in contact with the arc-shaped wall of the garbage can 3. The top of the arc-shaped shell wall of the garbage can 3 is provided with a strip-shaped sewage inlet 31 which is parallel to the extending direction of the winding roller 22.

The working principle of the solution of the cleaning device 2 and the garbage can 3 provided in the present embodiment is described below with reference to fig. 5:

taking the direction in fig. 5 as an example, the body 1 travels leftwards during operation and then sequentially cleans dirt on the path. Since the height of the garbage can 3 is higher than the ground, the dirt can pass through the gap between the garbage can 3 and the ground and reach the winding roller 22. The roll 22 is operable to wind a sheet of tissue 24. The tissue 24 used in this embodiment is typically made of a fiber-rich material such as tissue or towel. Since the winding roller 22 is in contact with the ground during operation, dirt on the ground cannot pass through the winding roller 22. The winding roller 22 rotates clockwise in the working process, and at the moment, the blocked heat conduction dirt is also stirred forwards by the winding roller 22 to reach the gap between the winding roller 22 and the arc-shaped wall surface of the garbage can 3.

Since the roll 22 of the present embodiment is wound with a cleaning towel 24, the roll 22 usually has two working effects during rotation: (1) The cleaning cloth 24 is equivalent to a rag, and can wipe off the dirt such as dust and water stain on the bottom surface. (2) Because the surface of the cleaning towel 24 is rich in fibers, the cleaning towel 24 can generate adhesion effect on some granular or flaky dirt, such as rice grains, fruit peels, fruit shells, wrapping paper and the like. Meanwhile, in combination with the squeezing action of the winding roller 22, the combination of the winding roller 22 and the cleaning cloth 24 can bring up the dirt and be wound into the gap between the winding roller 22 and the arc-shaped shell wall of the garbage can 3.

When the winding roller 22 is further rotated, the dirt passes through the strip-shaped dirt inlet 31 at the garbage can 3, and the dirt is not squeezed at the position, so that the dirt falls off from the surface of the winding roller 22 and falls into the inner cavity of the garbage can 3. In order to ensure that the dirt can be accurately trapped at the strip-shaped dirt inlet 31 and can not move forward, the baffle 32 which extends towards one side of the winding roller 22 can be arranged at the upper edge of the strip-shaped dirt inlet 31 of the garbage can 3.

In this embodiment, the surface of the winding roller 22 is provided with an elastic layer 220, and the elastic layer 220 may be in the form of a strip with a brush surface or a flexible pad, and the brush surface or the flexible pad extends along the axial direction of the roller body and is radially spaced. These resilient layers 220 are compressed and deformed by hard dirt such as stones and stones during the "sweeping" action and transport the dirt in a "compressed" state between the roller 22 and the curved wall of the receptacle 3. This allows the dirt to be "flicked" into the trash by the deformation restoring force of the elastic layer 220 when the dirt reaches the strip-shaped dirt inlet 31. The non-dust dirt can be effectively collected without vacuum adsorption.

The elastic layer 220 in this embodiment is spaced apart from the roller 22, and can be arranged in various irregular arrangements, such as multiple arrangements of bristles implanted on the surface of the roller 22, or a plurality of irregular stripe-like "ribs" arranged on the surface of the roller 22 in the manner of a deep-striped tire. The irregular channel can also generate the effect of enabling dirt to be clamped in the cleaning process, and the cleaning effect of the dirt is improved. When it is to be emphasized: although the dirt is clamped into the gap between the winding roller 22 in the cleaning (from the bottom to the stage blocked by the winding roller 22) and conveying state (from the stage located in the gap between the winding roller 22 and the arc-shaped wall surface of the garbage can 3), the cleaning cloth 24 is always in a tight state due to the rotation of the winding roller 22 because the surface of the winding roller 22 is wound with the cleaning cloth 24; the cleaning sheet 24 also generates a force to eject the dirt when the dirt reaches the position of the strip-shaped dirt inlet 31.

Furthermore, in actual product production and application, the best cleaning results are obtained when the ribs or bristles on the roller 22 are distributed in strips along the axis of the roller 22, and the better cleaning results are obtained when the ribs or bristles are arranged according to an undulating curve than when the ribs or bristles are arranged in a straight line. For example, the present embodiment illustrates the elastic layer 220 in a curved strip shape.

Comparing the scheme provided in this example with other conventional schemes: the product provided by the embodiment realizes the functions of simultaneously collecting larger granular or flaky dirt and cleaning stains and dust on the ground only by a set of simple cleaning devices 2. The cleaning effect is better and the equipment cost is greatly reduced. Meanwhile, the cleaning towel 24 in the scheme is very convenient to replace, and can be directly discarded and collected in the garbage can 3 after being dirty; the operation of the cleaning towel 24 changing process is very simple and highly automated. In addition, the product that this embodiment provided need not to adopt high-speed motor to produce vacuum negative pressure, just can effectively collect great filth and rubbish, consequently can effectively overcome the noise problem in the high motor vacuum adsorption scheme for high cleaning machines people's operation process is quieter, improves user's use and experiences.

In a more optimized scheme of this embodiment, a set of lifting mechanism is further provided in the cleaning device, and the lifting mechanism is used for driving the winding roller 22 and the driving mechanism 23 thereof to lift and lower in the vertical direction. When the lifting device controls the winding roller 22 to move up and down, the height of the winding roller 22 from the ground and the pressure between the winding roller 22 and the ground can be effectively adjusted, so that the optimal cleaning effect can be generated on different types of ground. For example, when the floor surface is uneven, the height of the winding roller 22 can be reduced appropriately so that the winding roller 22 is pressed more tightly against the floor surface. When the pressure between the winding roller 22 and the ground is too high, the noise is obviously generated or the cleaning cloth 24 is seriously abraded, so that the ground clearance of the winding roller 22 can be properly increased. In the practical application process, the lifting mechanism can be realized by actuators such as a tug assembly, an air cylinder and an electric cylinder.

In addition, in order to prevent the winding roll 22 from collecting the dirt, the dirt with an excessive volume is blocked between the winding roll 22 and the arc-shaped wall surface of the garbage can 3. The lifting mechanism can also adopt a mechanism with multidirectional movement adjustment, so that not only can the vertical height adjustment be realized, but also the distance between the garbage can 3 and the winding roller 22 can be adjusted. If the phenomenon of easy blockage occurs in the cleaning process, the gap between the garbage can 3 and the winding roller 22 is properly increased; this can improve the effect of collecting different sizes of garbage by the cleaning robot provided by the present embodiment.

The fastener 221 functions to securely wind the cleaning sheet 24 around the winding roll 22, and thus can be implemented in various solutions. Considering that the roll 22 rotates continuously in actual operation, the cleaning cloth 24 can be stably wound on the roll 22 during the rotation of the roll 22 by only fixing the clean end on the axial surface of the roll 22. In the solution of the present embodiment, the cleaning sheet 24 can be fixed in different ways. Specifically, in this embodiment, the fastening member 221 may be a strip clip extending along the axial direction of the winding roller 22 or a hook and loop fastener applied to the outer surface of the elastic layer 220. The strip clamp is configured as shown in fig. 6 and is mounted on the roll surface of the take-up roll 22. As shown in fig. 7, the principle of the strip clamp is to clamp one side edge of the cleaning sheet 24 by a clamp, thereby preventing the cleaning sheet 24 from falling off the winding roller 22. The hook-and-loop type of the hook-and-loop fastener is simpler, a hook patch of the hook-and-loop fastener can be mounted on the wall surface of the winding roller 22 or the upper surface of the elastic layer 220, when the cleaning cloth 24 is made of fabric, the cleaning cloth 24 itself is equivalent to a loop surface, and the hook surface can be accurately adsorbed with the loop surface. If the cleaning sheet 24 does not use a fabric, the desired cleaning sheet 24 may be made from a composite material having loops on the opposite side. Of course, in practical applications, the fastening element 221 may also take other possible solutions, which are not illustrated in this embodiment.

The strip-shaped clamp provided by the embodiment can adopt an electric control scheme, so that the polluted cleaning towel 24 can be released and replaced conveniently in the using process. And the fastening mode of the magic tape can also have the effect of convenient replacement. For example, in a more optimized scheme as shown in fig. 8, the movable barrier 32 which can be controllably extended and retracted is designed as the barrier 32 at the strip-shaped dirt inlet 31 of the garbage can 3. The distance between the movable baffle 32 and the winding roller 22 is adjustable. The movable flap 32 is used to scrape off contaminants from the surface of the cleaning sheet 24 or to cut off the cleaning sheet 24 to be replaced. When the movable barrier 32 is in a normal, unextended state, it acts as a "stop" for scraping contaminants off the surface of the cleaning pad 24. When the movable flap 32 is extended, it acts as a "blade" that cuts and scrapes the cleaning sheet 24 wound on the roll 22.

In other embodiments, a supply device 4 for the cleaning sheets 24 may be provided in the body 1, the supply device 4 being mounted on the support 21 of the cleaning device 2, the supply device 4 storing the cleaning sheets 24 to be extracted. The feeding device 4 of the present embodiment is a box structure. As shown in fig. 9 and 10, the replaceable cleaning sheets 24 are stored in a broken-off elongated shape (in the form of a household roll paper or a paper towel) in a housing of the feeding device 4, and the housing is provided with a mechanism for releasing and/or cutting off the cleaning sheets 24, and the feeding device 4 of the present embodiment is an automatic device which realizes automatic replacement of the cleaning sheets 24 in cooperation with the movable shutter 32. Of course, in other embodiments, the technician service may manually or semi-automatically replace the desired cleaning wipe 24.

In a more optimized solution in this embodiment, the bottom surface of the trash can 3 is further provided with a detection device 5 for evaluating the cleanliness of the ground. The detection result of the detection structure is transmitted to the controller of the roller cleaning robot and serves as reference data for the controller to adjust the frequency of replacement of the cleaning sheet 24.

As shown in fig. 11, the detecting device 5 in the embodiment has a downward transparent window, and a corresponding photoelectric sensor array is arranged inside the window; when the detection device 5 works, dust or light dirt is adsorbed on the window through controllable electrostatic action, then the content of the adsorbed pollutant is detected through the sensor array, the content is used as an evaluation result of abundant dirt in the bottom surface, and finally a detection result used for representing the cleanliness of the ground is output. The controller adjusts the frequency of cleaning changes based on the cleanliness levels detected during use, and extends the cleaning towel 24 change cycle when floor cleanliness is always high during use. When floor cleanliness is always low during use, the frequency of replacement of the cleaning sheet 24 is suitably increased.

The upper part of the garbage can 3 of the embodiment comprises a transparent upper cover which can be opened and closed. The upper portion of fuselage 1 that the upper cover can set up, the user of being convenient for observes the filth stock in the garbage bin 3 in real time, when the rubbish of collecting in garbage bin 3 is more, then can derive rubbish through opening the upper cover. In particular, the garbage can 3 itself can be designed to be a detachable structure, and after the garbage is full, the garbage can 3 can be directly disassembled and washed to lead out the garbage contained inside.

In addition, in order to improve the cleaning effect, a spraying device is further provided in the body 1 of the product of the present embodiment, and the spraying device is used for spraying liquid detergent, disinfectant or wetting agent to the cleaning towel 24 or the ground to be cleaned. Further, the product of the embodiment has a disinfection function and a stronger dust and oil removing function. In addition, as shown in fig. 12, in one cleaning robot, a plurality of cleaning devices 2 may be installed, each cleaning device 2 being arranged in a traveling direction of the body 1, a front cleaning device 2 being used to sweep and a rear cleaning device 2 being used to wipe, disinfect, or degrease the ground.
