Description

Technical Field

[0001] The utility model relates to the technical field of blackboard erasers, in particular to an intelligent blackboard eraser capable of automatically cleaning a blackboard. Background Art

[0002] In traditional teaching and working environments, teachers are used to writing on the blackboard with chalk to help students understand the content of their teaching and speeches. Due to the limited size of the blackboard, after the blackboard is filled, a blackboard eraser is usually used to erase the chalk writing on the blackboard.

[0003] However, a blackboard eraser needs to be manually wiped by a person, and after wiping, the dust on the blackboard eraser needs to be cleaned to ensure that the chalk writing on the blackboard is subsequently wiped clean. This process is quite time-consuming, and teachers often need to pause their lectures to complete it, wasting precious class time. Therefore, some manufacturers have developed blackboard erasers that can automatically wipe the blackboard. For example, Chinese utility model patent with publication number CN211031937U discloses an automatic blackboard eraser, which is adsorbed on a metal blackboard through a magnetic track by setting an upper rolling mechanism and a lower rolling mechanism, and uses a motor to drive the track to move, thereby realizing the function of the blackboard eraser automatically wiping the blackboard.

[0004] However, the above technical solution only uses the soft eraser on the blackboard eraser to clean the chalk writing. The principle of the soft eraser to clean the chalk writing mainly relies on friction. The greater the friction, the better the cleaning effect. The magnitude of the friction is proportional to the pressure of the blackboard eraser on the blackboard. When people manually wipe the blackboard, for the difficult-to-erase areas, they generally apply greater pressure to the blackboard eraser to increase the friction to achieve a better cleaning effect. In the above solution, the magnetic attraction of the crawler is certain, and the friction cannot be increased by pressurization. If the magnetic attraction is blindly increased, the energy consumption of the crawler will increase. Therefore, the above solution is not ideal for the cleaning effect of the blackboard, and manual assistance is still needed in many cases to wipe the blackboard clean. Utility Model Content

[0022] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0023] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0024] Embodiment 1

[0025] Combination Figures 1 to 3 As shown, a smart blackboard eraser includes a housing 1, and two parallel magnetic tracks 2 are installed at the bottom of the housing 1. The magnetic tracks 2 can run closely on the vertical blackboard to prevent the smart blackboard eraser from falling. The two magnetic tracks 2 are driven by two motors respectively, and both motors are controlled by a controller. The controller can be a single-chip microcomputer. The single-chip microcomputer controls the rotation of the two magnetic tracks 2 to drive the housing 1 to move forward. When turning, by controlling the speed of the two magnetic tracks 2, the inner track rotates slowly and the outer track rotates quickly to complete the turning of the housing 1.

[0026] The shell 1 takes the forward direction as the front side, and a horizontal brush 31 and two vertical brush 32 are arranged at the bottom of the shell 1. The horizontal brush 31 is arranged perpendicular to the magnetic track 2, and the vertical brush 32 is arranged parallel to the magnetic track 2. The horizontal brush 31 and the vertical brush 32 are both strip-shaped, which can be rags or nylon brushes. The horizontal brush 31 is located at the front side of the bottom of the shell 1, and the two vertical brushes 32 are located on the left and right sides of the bottom of the shell 1, respectively, on the outside of the two magnetic tracks 2. The horizontal brush 31 is used to wipe the stains on the blackboard, and the vertical brush 32 can wipe the left and right sides again on the one hand, and can clean the positions that the horizontal brush 31 fails to clean when the shell 1 turns on the other hand.

[0027] A dust suction assembly is also installed on the shell 1, and the dust suction assembly includes a dust collecting bucket inside the shell 1 and a dust suction port 8 connected to the dust collecting bucket through a pipe. The dust suction port 8 is located between the two magnetic tracks 2 and is used to absorb dust on the blackboard. A water spray assembly and a drying assembly are also provided on the shell 1.

[0028] The water spray assembly is installed on the front side of the shell 1, including a plurality of sprayers 4, which are arranged to be tilted downward and are used to spray water onto the blackboard in front of the smart blackboard eraser. The sprayers 4 are connected to a water pump through a water supply pipe 40, and the water pump is connected to a water storage box, which is installed in the shell 1.

[0029] The drying component includes a heating wire and a fan arranged in the hot air gun 5. The fan blows the hot air generated by the heating wire to the air outlet. The air outlet of the hot air gun 5 is located on the rear side of the bottom of the shell 1. After the horizontal brush 31 and the longitudinal brush 32 erase the blackboard, and the dust collection component absorbs the dust on the blackboard, the blackboard is dried, so that the water on the blackboard evaporates quickly and can be quickly put into teaching use.

[0030] like Figure 1 and Figure 2 As shown, a camera 6 is also installed on the front side of the housing 1, and infrared sensors 7 are installed on the front side and the left and right sides of the housing 1. The camera 6 and the infrared sensor 7 are electrically connected to the single-chip microcomputer as a controller. The camera 6 collects the blackboard image in front of the intelligent blackboard eraser and transmits it to the single-chip microcomputer. The single-chip microcomputer determines whether there are stains and dust on the blackboard in front that need to be cleaned, as well as the position of the stains and dust. Then the single-chip microcomputer can drive two motors to run and change the output speed, thereby controlling the forward direction of the intelligent blackboard eraser, and can quickly move to the position that needs to be cleaned for cleaning, rather than blindly cleaning the entire blackboard, which greatly improves the efficiency of cleaning the blackboard. The role of the infrared sensor 7 is to sense obstacles in front of the intelligent blackboard eraser and on the left and right sides, as well as the distance between the sensing housing and the edge of the blackboard, so that the single-chip microcomputer can determine the subsequent forward route to prevent the intelligent blackboard eraser from hitting obstacles or stopping at the edge of the blackboard.

[0031] When cleaning the blackboard, the intelligent blackboard eraser of the utility model first uses the water spraying component to spray water toward the blackboard in front, and then the housing 1 continues to move forward to use the horizontal brushing member 31 and the longitudinal brushing member 32 to brush the blackboard after the water spraying, and the dust suction component absorbs the dust at the same time, and finally the drying component at the rear quickly dries the brushed blackboard. The intelligent blackboard eraser can not only automatically clean the blackboard, but also greatly improve the cleaning effect compared with the prior art. At the same time, the drying component can quickly dry the cleaned blackboard, so that it can be quickly put into use, and will not affect the teacher's class rhythm and teaching efficiency, and is suitable for promotion and use.
