For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] In view of the low intelligence level and large dust of existing blackboard erasers, the embodiments of the present application provide a nano robot blackboard eraser, such as Figure 1 , Figure 7 and Figure 8 The above is a schematic diagram of the partial structure of a nano robot blackboard eraser of this embodiment. Figure 1 Place in the direction shown, Figure 1 The lower part is its front end, Figure 1The upper part in the figure is its rear end. At this viewing angle, the main body is the gripping part 2 of the nanorobot. A solar panel 1, an electronic control panel 4 and a master switch 7 are arranged in the middle of the gripping part 2. Finger contact areas are arranged on both sides of the gripping part 2. A sensing window of an image sensor 6 is exposed at the front end of the gripping part 2. The solar panel 1 is connected to the housing 3 through epoxy resin glue 5. The electronic control panel 4 has display and control functions, and the blackboard eraser can be controlled by inputting instructions on the electronic control panel 4. The master switch 7 can freely control the use and rest of the electrical components of the blackboard eraser according to the opening and closing of the switch. The blackboard eraser can be powered off and rested when it is not needed for work, thereby extending its service life and reducing energy loss. Figure 1 The side in the middle that is in contact with the paper surface is the working surface of the blackboard eraser. From this perspective, the blackboard eraser is in the shape of a trapezoid with a larger front and a smaller back. Figure 7 From the perspective shown in the figure, it can be seen that the blackboard eraser is in the shape of a trapezoid with a larger front and a smaller back. Figure 8 From the perspective shown, it can be seen that the blackboard sheet is in a trapezoidal shape with a smaller portion near the working surface and a larger portion away from the working surface. The shape design of the blackboard eraser conforms to the palm-shaped design of ergonomics, is convenient to hold, and is not easy to fall.

[0052] Therefore, the blackboard eraser of this embodiment has a shell 3 of the above-mentioned shape, wherein the shell 3 has at least one plane as a working surface for erasing the blackboard, and a cover body cooperates with the plane to provide an accommodating space.

[0053] In the present embodiment, the housing 3 is made of polypropylene plastic. In the accommodation space inside the housing 3, there are erasing and dust collection components, driving components and control systems. The erasing and dust collection components and driving components of the present embodiment are all based on nanorobot technology. The nanorobot can be placed inside the blackboard eraser due to its small size, wherein the driving component is responsible for driving the blackboard eraser to move as a whole, and the erasing and dust collection components are configured with an erasing and cleaning component responsible for wiping the chalk marks on the blackboard and removing the dust. Therefore, the working surface of the present embodiment needs to cooperate with the driving component so that the erasing and cleaning component of the nanorobot responsible for wiping can contact the chalk marks and cannot make the nanorobot itself overflow from the blackboard eraser. Therefore, the plane in the present embodiment has a porous structure, and the silica material can be selected. The pore size of the porous structure is smaller than the size of the nanorobot and larger than the outer diameter of the chalk dust and the erasing and cleaning component. In this way, the nanorobot passes through the porous structure and the chalk marks through the erasing and cleaning component configured thereon to generate friction between the porous structure and the chalk marks, so that the dust is separated from the blackboard and passes through the porous structure under the action of the erasing and dust collection component to enter the inside of the blackboard eraser. The plane and the side of the blackboard in contact are smooth, and the friction between the plane and the blackboard is almost zero, which facilitates the movement of the blackboard eraser. Therefore, the present embodiment can realize automatic erasing and dust-free operation of the blackboard by realizing accurate control of the erasing and dust-collecting assembly and the driving assembly through the control system.

[0054] Specifically, Figure 2 As shown in FIG. 1 , it is a schematic diagram of the structure of the wiping and dust collection assembly of this embodiment. Figure 2 As shown, the wiping and dust collection component includes a first shell 9, which is fixed in the inner cavity of the shell 3 through a groove structure, and the first shell 9 is made of polyethylene. The first shell 9 has a first opening and the first opening fits the plane. A first nanorobot is accommodated between the first shell 9 and the plane. The first nanorobot is equipped with a wiping and cleaning component. Optionally, the wiping and cleaning component can be some tiny cilia. In this embodiment, the shape of the first shell 9 is adapted to the shape of the shell 3, including Figure 2 The left half shell part and the right half shell part in the first shell 9 are both roughly rectangular and connected in the middle, and both of the left half shell part and the right half shell part have an opening on one side of the paper in the direction of the figure and fit the plane. The first nanorobot can move in the first shell 9 and contact the first plane.

[0055] like Figure 2 The wiping and dust collection assembly further includes a dust separation system, and the dust separation system includes:

[0056] The air duct 12 is parallel to the plane, and has a first opening and a plurality of second openings, and the remaining area is closed. The air duct 12 is connected with the first shell 9 through the first opening, and a filter 11 is arranged between the second opening and the first shell 9, and the second opening is connected with the first shell 9 through the filter 11, and the aperture of the filter 11 is larger than the size of the first nanorobot and smaller than the size of the dust.

[0057] The fan 10 is disposed in the air duct 12 and is located between the first opening and the second opening, so that the first opening and the second opening are located on both sides of the upstream and downstream of the wind direction of the fan 10. A plurality of partitions 14 are connected to the second opening, and the plate surface of the partition 14 is perpendicular to the wind direction at the location, and the plate surface of the partition 14 occupies a part of the cross section of the air duct 12 at the location.

[0058] In this embodiment, the first shell 9 is built with a guide plate 8, which is arranged along the front-to-back direction of the first shell 9 and has only a small gap with the inner side of the first shell 9. For example, the left half shell part in the figure is divided into two inner and outer parts in the left-right direction by the guide plate 8 therein, and the two parts are connected at the front and back ends. The right half shell part in the figure is divided into two inner and outer parts in the left-right direction by the guide plate 8 therein, and the two parts are connected at the front and back ends. The plate surface of the guide plate 8 faces the filter 11 to form a block for the first nanorobot entering the first shell 9 from one side of the filter 11, so that the first nanorobot can move from the inner side of the first shell 9 to the front end of the blackboard eraser under the guidance of the guide plate 8, and then move from the outer side of the first shell 9 to the rear end of the blackboard eraser until it enters the air duct 12 again, so that the flow direction of the first nanorobot is relatively uniform and the movement is controllable.

[0059] like Figure 2The erasing dust collection assembly shown, the left half shell part and the right half shell part are connected at the rear end of the blackboard eraser, the air duct 12 is arranged between the left half shell part and the right half shell part along the front and rear direction of the blackboard eraser, and one end of the air duct 12 is connected to the position where the left half shell part and the right half shell part are connected, that is, a three-way node is formed at the rear end of the blackboard eraser. Two filter screens 11 are respectively arranged on the left and right sides of the air duct 12, and are staggered with each other. The fan 10 rotates, and 4 layers of filtration are formed on both sides of the air duct 12 located downstream of the fan 10. When the fan 10 is powered on and started, the fan blades start to rotate at high speed. The special shape and angle of the fan blades are set so that a negative pressure area is formed in front of the fan 10 during the rotation process, and the surrounding air will flow to the negative pressure area from all directions under the action of the pressure difference. The air containing dust will also be involved and begin to flow in the direction of the negative pressure fan 10. The first nanorobot and dust enter the air duct 12 from the first shell 9 under the action of the fan 10. After passing through the filter 11, the nanorobot can pass through the filter 11 and re-enter the first shell 9. However, the dust cannot pass through the filter 11 due to its volume being larger than the filter 11 and remains in the air duct 12. Moreover, due to the action of the partition 14, the dust cannot enter the first shell 9 again.

[0060] like Figure 5 The driving assembly shown includes a second shell 13, which is fixed in the inner cavity of the shell 3 through a groove structure. The second shell 13 has a second opening and the second opening fits the plane, and a second nanorobot is accommodated between the second shell 13 and the plane. In this embodiment, the second shell 13 includes two parts, namely a left shell part and a right shell part, and the two parts are not connected to each other, and both parts are roughly rectangular. In order to make the internal space of the entire blackboard eraser compact, the first shell 9 is arranged on the periphery of the second shell 13, that is, the left half shell part of the first shell 9 is arranged on the left side of the left shell part of the second shell 13, and the right half shell part of the first shell 9 is arranged on the right side of the right shell part of the second shell 13. The second shell 13 is relatively fixed to the shell 3 of the blackboard eraser, and the second nanorobot moves inside the second shell 13, and the shell 3 of the blackboard eraser moves as a whole by hitting and pushing the inner wall of the second shell 13.

[0061] In an embodiment of the present invention, the control system has built-in control software, which is used to control the first nanorobot to move toward the plane and adhere to the plane to perform an erasing action, and to control the second nanorobot to move parallel to the plane and in the indicated direction to push the plane to move in accordance with the blackboard.

[0062] In some preferred embodiments, the control system is implemented based on an STM32 chip, and the control instructions may include moving direction, speed, acceleration, action of the actuator, wiping force, etc.

[0063] In some optional embodiments, the second nanorobots are all magnetic nanorobots, and a plurality of first coils axially parallel to the plane of the blackboard eraser are arranged around the periphery of the blackboard matching the blackboard eraser. When the first coils are energized, a magnetic field parallel to the plane of the blackboard eraser is generated. When the blackboard eraser is attached to the blackboard, the blackboard is located in the magnetic field. Therefore, by energizing different first coils in combination, different magnetic field directions and sizes can be obtained, thereby facilitating the control of the second nanorobot to move in a specified direction.

[0064] In some optional embodiments, the first nanorobot is a magnetic nanorobot, and the blackboard matched with the blackboard eraser is built with a plurality of second coils axially perpendicular to the blackboard eraser plane, and the second coils are evenly distributed in the blackboard plane. When the second coils are energized, a magnetic field perpendicular to the blackboard eraser plane is generated. A magnetic material is set on one side of the erasing and cleaning component of the first nanorobot, and the magnetic poles are opposite to the magnetic properties of the blackboard surface. Then, the first nanorobot can be attracted and adsorbed to the working surface by energizing the coil to form a magnetic field perpendicular to the blackboard surface, so that the first nanorobot is attracted and adsorbed to the working surface, so that the friction between the erasing and cleaning component of the first nanorobot and the chalk handwriting is generated with the overall movement of the blackboard eraser, so that the chalk powder is separated from the blackboard. The fan 10 is turned on at the same time during the erasing process, but the wind force of the fan 10 is controlled to be less than the attraction of the blackboard to the first nanorobot, so that the dust generated in real time during the erasing process can enter the interior of the blackboard eraser to achieve dust-free wiping. After wiping is completed, the coil in the blackboard is controlled to be powered off, and the first nanorobot no longer adheres to the work surface, but moves toward the air duct 12 under the action of the fan 10. After a period of time, the first nanorobot is separated from the dust on it, and the first nanorobot is completely located in the first shell 9. If there is no wiping task thereafter, the fan 10 can be stopped.

[0065] The above-mentioned nanorobot blackboard eraser can realize automatic dust-free wiping of the blackboard, does not affect human health and is environmentally friendly.

[0066] In certain preferred embodiments, Figure 3 , 5 As shown in Figure 6, the accommodating space also includes a magnetic attraction component 24, a disinfection component and a heat dissipation component. The magnetic attraction component 24, the disinfection component and the heat dissipation component can be fixed inside the shell 3 through a groove structure.

[0067] The blackboard itself is a magnetic blackboard, and the magnetic attraction assembly 24 is a magnetic adsorption material, which can realize that the blackboard eraser is adsorbed on the blackboard. No matter whether the blackboard itself is powered on, it does not affect that the blackboard eraser can be fixed on the blackboard.

[0068] like Figure 6 As shown, an implementation of a disinfection component is provided. The disinfection component is in the form of an ultraviolet lamp 29 and is fixed at the center of the inner cavity of the shell 3 for performing ultraviolet irradiation disinfection on the inside of the shell 3 .

[0069] like Figure 3 The above is an implementation of the heat dissipation component, which includes a graphite heat sink 16, a thermally conductive silicone rubber 18 and a heat dissipation channel 15. The heat dissipation channel 15 is arranged in a serpentine manner in the accommodation space, and the channel opening 17 of the heat dissipation channel 15 is located on the housing 3; there are multiple graphite heat sinks 16, and the multiple graphite heat sinks 16 are evenly arranged along both sides of the serpentine channel between the serpentine channel and the housing; the thermally conductive silicone rubber 18 fills the gap formed between the heat dissipation channel 15 and the graphite heat sink 16.

[0070] When each part of the blackboard eraser is working, a large amount of heat generated by the heating element can be quickly transferred by contacting with the heat dissipation channel 15, avoiding heat accumulation in the local area, resulting in damage due to excessive temperature. The heat dissipation channel 15 can also evenly distribute the heat to a larger heat dissipation area. Through the design of the channel, the heat can be diffused in different directions, so that the temperature of the entire heat dissipation system is more uniform, avoiding the situation of local overheating. The thermal conductivity of graphite is relatively uniform in all directions, which enables it to evenly distribute the heat in the entire heat dissipation area, avoiding the situation of local overheating. This uniform heat dissipation characteristic is particularly important for the electronic control panel 4 in the blackboard eraser, which can extend its service life. And the graphite heat dissipation material is usually very thin, and efficient heat dissipation can be achieved without increasing the volume and weight of the device. At the same time, graphite has a certain flexibility and can be bent and folded according to different device shapes. Since there are devices such as negative pressure fans 10 in the blackboard eraser, the air flowability is large, and graphite is not easy to oxidize in the air, and its performance can be kept stable for a long time. Therefore, compared with other metal heat dissipation materials, graphite does not need to be subjected to special surface treatment to prevent oxidation, which reduces the cost of use and the difficulty of maintenance. In addition to having good heat dissipation performance, the thermally conductive silicone 18 also has good insulation performance, which can provide reliable electrical isolation between electronic components and radiators. This can prevent short circuits and leakage between electronic components and protect the safe operation of various electrical components inside the blackboard eraser. The thermally conductive silicone 18 can also play a role in moisture and dust prevention. It fills the gap between the electronic components and the radiator, which can effectively prevent moisture and dust from entering, thereby extending the service life of the electronic equipment.

[0071] In some preferred embodiments, a temperature sensor is further included. The temperature sensor is controlled by the control system and is used to detect the temperature inside the blackboard eraser and transmit it to the control system to monitor the temperature of the components inside the blackboard eraser.

[0072] In some preferred embodiments, an image sensor 6 is also provided in the accommodation space. Figure 1 As shown, the image sensor 6 is fixed in the housing 3 through a groove structure and its image sensing window is located at the front end of the housing 3. The image sensor 6 is controlled by the control system and is configured to acquire an image of the outer area of ​​the housing 3 in response to the control of the control system and transmit it to the control system, so that the control system controls the movement of the first nanorobot and the second nanorobot according to the image.

[0073] In some embodiments, the blackboard eraser is also provided with an energy storage and supply part, and a rechargeable battery 19 is provided inside the blackboard eraser, which can provide necessary energy support for the operation of multiple electrical components such as ultraviolet lamps, sensors, etc. The surface of the blackboard eraser is covered with a solar panel 1 of a certain area, and the rechargeable battery 19 can be charged by solar energy, thereby increasing the proportion of clean energy use and reducing pollution to the environment; at the same time, an external charging interface 3421 is designed on the side of the blackboard eraser, which can be charged through an external connection to reduce the insufficient power supply caused by environmental factors. The rechargeable battery 19 is equipped with a heat dissipation column 22 to accelerate its heat dissipation.

[0074] In this embodiment, the internal circuit 23 of the blackboard eraser is wrapped by the glass fiber tube 20, which protects the circuit and prevents damage to components caused by leakage or circuit damage. The glass fiber tube 20 also has a certain flexibility and can be bent and cut according to actual needs. Multiple wires are wrapped together to form a neat wire bundle, making the blackboard eraser circuit more neat and beautiful, and easy to maintain and manage.

[0075] In some preferred embodiments, the control system controls the movement of the first nanorobot and the second nanorobot according to the image, comprising the following steps:

[0076] Step S101: Obtain information of the area to be erased according to the image.

[0077] Step S102: obtaining the initial position of the blackboard eraser itself, and planning an erasing path according to the initial position of the blackboard eraser itself and the information of the area to be erased.

[0078] Step S103, obtaining a movement control strategy of the second nanorobot according to the erasing path, and controlling the second nanorobot to move according to the movement control strategy, so that the blackboard eraser moves along the erasing path driven by the second nanorobot.

[0079] Step S104, obtaining the real-time positioning of the blackboard eraser itself during the movement of the blackboard eraser, and in response to the real-time positioning of the blackboard eraser itself within the range of the to-be-erased area, controlling the first nanorobot to move toward the plane and adhere to the plane to perform an erasing action.

[0080] In some preferred embodiments, controlling the first nanorobot to move toward the plane and adhere to the plane to perform an erasing action includes:

[0081] The second coil in the blackboard corresponding to the current position of the blackboard eraser is controlled to be energized to generate a magnetic field, so that the first nanorobot moves to the plane under the action of the magnetic field.

[0082] The blackboard eraser can automatically identify the area to be erased based on the image. Such erasing does not discriminate the content on the board. For example, the blackboard eraser can be set to automatically identify and erase at the end of each class, or when the user thinks that the blackboard content needs to be switched as a whole, the user can choose to let the blackboard eraser automatically identify and erase all. However, in some cases, only a part needs to be erased, for example, only the content on the left half of the blackboard needs to be erased. Therefore, in some preferred embodiments, the information of the area to be erased based on the image includes the following steps:

[0083] Step S1011: transmitting the image to a display device for displaying to a user so that the user can select an area to be erased;

[0084] Step S1012: obtaining information of the area to be erased in response to receiving a selection signal of the area to be erased from the user.

[0085] The area to be erased may be an area circled by a user using a touch screen or a mouse, and the system determines a closed area as the area to be erased in response to the user's selection; obtaining the initial positioning of the blackboard eraser, and planning an erasing path according to the initial positioning of the blackboard eraser and the information of the area to be erased, wherein the blackboard eraser erases the area to be erased selected by the user, including:

[0086] Obtain a non-to-be-erased area between its own initial positioning and the area to be erased, identify a blank area in the non-to-be-erased area, determine whether at least one first erasing path can be constructed by passing through only the blank area so that the blackboard eraser can move from its own initial positioning to the area to be erased, if so, plan the shortest path in the first erasing paths as the erasing path, if not, construct several second erasing paths passing through the non-to-be-erased area so that the blackboard eraser can move from its own initial positioning to the area to be erased, identify the size of the non-blank area in the second erasing path passing through the non-erased area, and select the second erasing path with the smallest non-blank area in the non-erased area as the erasing path.

[0087] By adopting the above method, the working efficiency and effect of the blackboard eraser are taken into consideration, and the path from the initial positioning of the blackboard eraser to the area to be erased only passes through the blank area without affecting other handwriting. In addition, even if the above embodiment inevitably needs to pass through the non-to-be-erased area, since the first nanorobot is not working at this time, the friction between the blackboard eraser and the blackboard surface is small and the handwriting will not be erased.

[0088] In some preferred embodiments, obtaining the movement control strategy of the second nanorobot according to the erasing path, and controlling the second nanorobot to move according to the movement control strategy, comprises the following steps:

[0089] Step S1031, obtaining a coil on-off control strategy according to the movement control strategy, and controlling the multiple coils built into the periphery of the blackboard and axially parallel to the blackboard eraser plane to be energized through the coil on-off control strategy, including controlling the combination of energized coils and the energization time and current, so that the second nanorobot moves under the action of the magnetic field generated by the above coils.

[0090] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included within the scope of the claims of the present application.
