The various technical features in the invention can be combined interactively on the premise of not conflicting with each other.

With reference to Fig. 1～Fig. 2, embodiment of the present invention: a kind of fully automatic blackboard cleaning wipe, comprises moving rod 1, and the side wall of described moving rod 1 is equipped with brush body 2, is characterized in that: comprises water spraying device, suction Dust device, drying device, mobile device,

The water spray device includes a water nozzle 3 installed on the side wall of the moving rod 1, a water storage tank 4 installed at the end of the moving rod 1, a water pump 5 installed on the water storage tank 4, and a water delivery pipe 6. The water pump 5 is connected with the water nozzle 3 through the water delivery pipe 6;

The dust suction device includes a dust absorption box 7 installed on the end of the moving rod 1, a conduit 8, a dust suction motor, and an air duct impeller 9, and the described air duct impeller 9 is installed on the side wall of the moving rod 1, so that The dust collection motor is installed in the air cylinder impeller 9, and the dust collection motor drives the air cylinder impeller 9 to rotate, and the air cylinder impeller 9 is connected with the dust absorption box 7 through a conduit 8;

The drying device includes a drying fan 10, a tuyere 11, and a heating wire. The heating wire is installed in the tuyere 11, and the drying fan 10 is connected to the tuyere 11. The drying fan 10 is 10 is installed on the moving bar 1;

The moving device includes a servo motor 12 installed on the moving rod 1, and pulleys are arranged at both ends of the moving rod 1, and the servo motor 12 is connected to the pulley by transmission;

A switch 13 is also included, and the switch 13 is connected with the water pump 5 , the vacuum motor, the drying fan 10 , the heating wire, and the servo motor 12 .

Guide rails 18 are installed at the upper and lower ends of the blackboard 17, and the two ends of the moving rod 1 are slidably connected with the guide rails 18 through pulleys. The moving rod 1 is equipped with a brush body 2, which can achieve a simple erasing effect while moving. Control the start, pause and forward and reverse of the servo motor 12 to control the range of cleaning, which can meet the teacher's various cleaning needs in class. The choice is not unique, the practicability is strong, the operation is simple, and the flexibility is high; If there are too many, and the board is not wet, the effect of wiping the blackboard will be poor, and there will be more dust left on the blackboard, which will affect the next writing. The water spray device can spray water mist through the water spray nozzle 3, moisten the blackboard, and assist other devices to better clean the blackboard. Integrated on the pole. Among them, the water storage tank is generally a 0.2-0.5L plastic water tank, and the water pump is a miniature electric centrifugal pump. The water is divided into fine jets and sprayed to the blackboard; the existing method of wiping the blackboard will generate more dust, and the dust suction device can absorb the dust generated when cleaning the blackboard, and solve the harm of dust to teachers and students. The device is mainly composed of a dust absorption box 7, a conduit 8, a dust collection motor, and an air duct impeller 9, which are integrated on the rod. After it is turned on, the vacuum motor rotates at a certain speed, so that negative pressure is generated inside the air duct impeller 9. Under the action of the internal and external pressure difference, the suction port sucks the dust and absorbs it in the detachable dust absorption box 7 at the end of the moving rod 1. The drying device can quickly dry the blackboard body wetted by the water spray device to achieve the effect of wiping and using immediately. The device is mainly composed of a drying fan 10, an air nozzle 11 and a heating wire, which are integrated on the rod. After it is turned on, the drying fan 10 rotates, the air is sucked in from the air inlet, and the airflow formed is blown out by the air nozzle 11. When the air passes through, the heating wire installed in the air nozzle 11 is energized and heated, and hot air is blown out, thereby realizing the drying function ;

Adding dust suction, water spray and drying devices to the moving rod 1 can simultaneously complete functions such as cleaning the blackboard, recycling dust, wetting and drying the blackboard, making the blackboard clean and wipe, spray water, vacuum and dry It integrates multiple functions into one body and realizes integration, so that the blackboard cleaning wipe can be separately installed on the original old-style blackboard, which greatly reduces the teaching expenses.

As a further preferred embodiment, several water nozzles 3 are provided, and the several water nozzles 3 are evenly arranged on the side wall of the moving rod 1 . Different water nozzles 3 and different spacings are set according to the size of the blackboard, and along with the movement of the guide rail 18, it is guaranteed that the water sprayed by the water nozzles 3 on the cleaning rod can wet the whole blackboard 17.

Further as a preferred embodiment, the cross-section of the moving rod 1 is rectangular, the cross-section of the brush body 2 is bow-shaped, and a Velcro 14 is arranged between the brush body 2 and the moving rod 1, so that The brush body 2 described above is connected with the side wall of the moving rod 1 through the Velcro 14 . The cross-section of the brush body 2 is bow-shaped so that the contact between the brush body 2 and the blackboard 17 is closer, and the cleaning effect is better. , the dust can accumulate in the dust grooves on both sides of the brush body 2, and then be absorbed by the dust collector;

As a further preferred embodiment, the brush body 2 is made of sponge material. The sponge material has better cleaning effect, strong adsorption capacity, good deformation recovery and long service life.

Further as a preferred embodiment, the upper and lower parts of the moving rod 1 are connected with an adjusting frame 15, the pulley is pivotally connected with the adjusting frame 15, and the moving rod 1 is slidably connected with the adjusting frame 15. The adjusting frame 15 is provided with a locking mechanism 16, and the locking mechanism 16 realizes the positioning of the moving rod 1 on the adjusting frame 15. Prolonged use will cause gaps in the contact between the brush body 2 and the blackboard 17, and the cleaning wipe will lose its cleaning function. The distance between the moving rod 1 and the blackboard 17 can be adjusted through the sliding connection between the moving rod 1 and the adjustment frame 15 to keep the brush body 2 contact with the blackboard 17, and a locking mechanism 16 is also provided to lock and position the moving rod 1, increase the adjustment function of the cleaning wipe, and improve the applicability and practicability of the cleaning wipe.

At the same time, the device has two cleaning modes to choose from, which are normal cleaning mode and deep cleaning mode. Ordinary cleaning mode is to meet the needs of teachers to clean the blackboard multiple times in a class. This mode is characterized by fast speed, and the movement mode of servo motor 12 can be directly controlled by switch 13 so as to drive the moving rod 1 to determine the cleaning position. , which can effectively improve classroom efficiency; the deep cleaning mode is used to remove the dust traces left by repeated use of the blackboard after each get out of class (or one day). This mode is accompanied by a water spray device and a drying device. Clean the blackboard. The teacher can realize the deep cleaning of the blackboard with one key, as follows: (1) press the switch 13, the water spray nozzle 3 installed on the rod will spray water mist, and the whole blackboard 17 can be wetted by the movement of the guide rail 18. In the process of water, it also realizes the functions of wiping and absorbing dust. (2) After cleaning the blackboard, the drying function can be realized by the drying device. Compared with the existing single technology, we can integrate multiple functions of cleaning, water spraying, vacuuming, and drying, and can choose the cleaning area according to the actual situation. The selection is not unique, the practicability is strong, and the operation Simple and flexible.

The preferred embodiments of the present invention have been described in detail above, but the invention is not limited to the described embodiments, and those skilled in the art can also make various equivalent modifications or replacements without violating the spirit of the present invention. These equivalent modifications or replacements are all within the scope defined by the claims of the present application.
