Description

Washing type blackboard cleaning device

The invention is a cleaning device, especially a water-washing blackboard cleaning device. The mobile board-wiping module is combined with a circulating water tank device, so that the body of the water-washing blackboard can be quickly cleaned and the water marks are scraped off.

At present, most of the existing educational institutions in China, in addition to using computer briefings for teaching during the course, also need to cooperate with the way of handwriting on the blackboard to strengthen the description, and the configuration during use is roughly divided into the following three categories:

1. The old dry board wiped with gypsum chalk: the equipment is cheap but its dust is extremely harmful to teachers and students, and it is easy to cause chronic, acute pneumonia, pneumoconiosis, etc., including skin diseases, dry skin, cracks, etc., in serious cases It is also accompanied by itching sensation, which makes the human body uncomfortable, and even causes acne, folliculitis... and other diseases, and it can also cause eye discomfort and inflammation. In addition, teachers usually use their throat very frequently, often using too much sound, and inadvertently inhale chalk dust, which makes some teachers' hoarseness and loss of voice increasingly serious, leading to the formation of chronic pharyngitis.

2. Whiteboard and whiteboard pen: The prices of commercially available whiteboard pens and whiteboards are very high. Although the whiteboard feels relatively clean, the organic volatile gas released by the whiteboard pen is more terrible and it is more harmful to the human body.

3. Washable blackboard with crayons: this method is dust-free, although it is excellent, but the wet-type board must be wiped with the dry-type board after wiping to use. In fact, it is found to be slow Not in a hurry, not as easy to use as imagined, because the dry-type wiper is mostly wet after many times of use, it takes an average of several minutes to dry the blackboard, not only the students' learning is interrupted, the teacher has to bend over many times after a class Wetting water in the sink is neither convenient nor comfortable, so there is still room for improvement in conventional techniques.

The invention discloses a water-washing blackboard cleaning device, which includes a water-washing blackboard body, a circulating water tank device, a mobile wiper module and a switch. The circulating water tank device has a water outlet structure, a power source, and a guide tube. A drainage pipe and a water tank, the water outlet structure is erected on the top of the water-washing blackboard body, the power source is connected to the water outlet structure and the guide pipe respectively, the guide pipe is connected to the water tank, and the water tank passes through the drainage pipe and the water wash The bottom of the blackboard body is combined; the mobile erasing module has a plurality of butt-type erasing structures and a transmission device; each of the erasing structures has an integrally formed cleaning part and a fixing part, the fixing part is vertically arranged on the cleaning A fixed groove is radially formed on one side of the member, and the other side of the cleaning member includes a wiping surface and a plurality of dewatering channels, each of which is axially symmetrically disposed on both sides of the wiping surface; the transmission device has a High-torque motor, a positioning plate, a plurality of upper guide wheels, a plurality of lower guide wheels, a plurality of support rods, an upper fixed seat and a lower fixed seat, the motor is set on a positioning plate, the positioning plate is located on the upper fixed seat The upper fixed seat is provided with the upper guide wheels, the lower fixed seat is provided with the lower guide wheels, and the two ends of each support rod are respectively stuck on the upper fixed seat and the lower fixed seat opposite A plurality of sets of holes are provided, a distance is maintained between each of the support rods, and a plurality of fixing holes are correspondingly provided, the fixing member of each of the wiper structures is disposed between the support rods, any one of the fixing groove and the corresponding fixing holes It is fixed by a joint; the switch is electrically connected to the circulating water tank device and the mobile wiper module.

With the above structure, the advantages of the present invention are as follows:

1. Automatic water spraying and recycling water: the water outlet structure provides automatic water spraying to the body of the water-washing blackboard, and the used water flows back to the water tank along the drainage pipe to achieve water recycling. Furthermore, a filtering device can be installed in the water tank to filter the used wastewater before use.

2. Automated blackboard wiping: The mobile eraser module can automatically wipe the body of the washed blackboard back and forth. In addition, with the circulating water tank device, when the water outlet structure sprays water, the cleaning member of the eraser structure can wipe synchronously And the effect of scraping water, so that the body of the washed blackboard keeps the writing surface dry.
