Abstract
The invention relates to an electric water-spraying dust-suction blackboard eraser. The upper end face of an eraser cover is fixedly connected with a motor, the front end of an output rotating shaft of the motor stretches into the eraser cover to be fixedly connected with a felt, a through hole is formed in the middle of the output rotating shaft of the motor, one end of the through hole is communicated with the air, the other end of the through hole is communicated with a suction inlet of a dust collector installed at the upper end of the motor, a water sprayer is installed at the position, beside the motor, on the eraser cover, a water outlet of the water sprayer is connected with a water pipe in the eraser cover, and a water outlet in the lower end of the water pipe is formed in the bottom of the eraser cover. The upper surface of the water sprayer is connected with a water storage box. According to the electric water-spraying dust-suction blackboard eraser, the character wiping felt is connected with the motor, the dust suction through hole is formed in the middle of the motor, the motor is connected with the dust collector through the through hole, and the water outlet of the water sprayer is connected with the water pipe in the eraser cover. When a blackboard is wiped, dust flying from the two sides of the blackboard eraser can be sucked into the dust collector, the dust is prevented from polluting classrooms and the air, and therefore indoor environment and the health of teachers and students are protected conveniently; meanwhile, dust generation is reduced through water spraying, and the elimination efficiency is increased.
Description
Technical field
The present invention relates to a kind of blackboard eraser, especially relate to a kind of electrical water jetting eraser board eraser of inhaling powder ash function that has.
Background technology
Existing blackboard eraser is to be made by the material of loading onto felt one class above plank and easily wipe letter written with chalk.In the time erasing the board, although letter written with chalk has been wiped, chalk dust flies upward everywhere, the hand of making dirty, clothes and face.Arm moves in turn back and forth when erasing the board, also sweat very, in addition, when moving in turn back and forth, also strengthen Air Flow, made the farther of diffusion that dust wafts, contaminated environment, long-term suction dust is very unfavorable to student and teacher's physical and mental health, and dust from flying is very unhygienic simultaneously, and the existing blackboard eraser life-span is short, waste of material is serious, does not meet the theory of national energy-saving environmental protection.
Summary of the invention
The present invention will provide a kind of electrical water jetting to inhale greyish black blackboard eraser; in the time of blackboard wiping; the dust that fly upward these blackboard eraser both sides can be inhaled in dust catcher; stop the pollution of dust to classroom and air; be conducive to protect indoor environment and teachers and students' health; and reduce dust by water spray and produce, improve elimination efficiency high.
For achieving the above object, technical scheme of the present invention is: a kind of electrical water jetting is inhaled greyish black blackboard eraser, comprise felt, wipe cover, motor, dust catcher, water jet, wipe on cover upper surface and be fixedly connected with motor, motor output revolving shaft front end stretches into wipe in cover and is fixedly connected with the felt of wiping in cover, in the middle of motor output revolving shaft, be provided with through hole, through hole one end is communicated with atmosphere, the other end is communicated with the suction inlet of the dust catcher that is arranged on motor upper end, the other water jet that is equipped with of motor is above covered in wiping, water jet delivery port is connected with the water service pipe of wiping in cover, water service pipe lower end delivery port is positioned at wipes cover bottom.
In the middle of felt bottom surface, be provided with one for collecting the conical bore of powder ash, and conical bore is connected with motor output revolving shaft intermediate throughholes.
Wipe on the excircle of cover bottom the sealing strip that prevents that powder ash from outwards flying upward is housed.Motor is DC micromotor.Above water jet, be connected with water storage case.
The beneficial effect that the present invention compared with prior art has is: the present invention adopts and wipes word felt connection motor, in the middle of motor, arrange and inhale powder ash through hole, be connected with dust catcher by through hole, and wipe and cover the other water jet that is equipped with of motor above, water jet delivery port is connected with the water service pipe of wiping in cover.In the time of blackboard wiping, the dust that fly upward these blackboard eraser both sides can be inhaled in dust catcher, has stopped the pollution of dust to classroom and air, is conducive to protect indoor environment and teachers and students' health, meanwhile, reduces dust produce by water spray, improves elimination efficiency high.And there is the features such as easy to use, laborsaving, simple in structure.
Brief description of the drawings
Fig. 1 is structure cutaway view of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figure 1, a kind of electrical water jetting is inhaled greyish black blackboard eraser, comprises felt 1, wipes cover 2, motor 3, dust catcher 4, sealing strip 7, water jet 8, water storage case 10.
Wipe mounted motor 3 on cover 2 upper surfaces, motor 3 output revolving shaft front ends stretch into wipe in cover 2 and are fixedly connected with the felt 1 of wiping in cover 2, in the middle of motor 3 output revolving shafts, be provided with through hole 5, through hole 5 one end are communicated with atmosphere, and the other end is communicated with the suction inlet of the dust catcher 4 that is arranged on motor 3 upper ends.Water jet 8 delivery ports are connected with the water service pipe 9 of wiping in cover 2, and water service pipe 9 lower end delivery ports are positioned at wipes cover bottom.Motor 3 is DC micromotor.Water jet 8 is connected with water storage case 10 above.
Felt is provided with one for collecting the conical bore 6 of powder ash in the middle of 1 bottom surface, and conical bore 6 is connected with motor 3 output revolving shaft intermediate throughholes 5.Wipe on cover 2 bottom excircles the sealing strip 7 that prevents that powder ash from outwards flying upward is housed.
When use, open motor 3 and dust catcher 4, make felt 1 rotate font on erasing blackboard face etc.Meanwhile, dust catcher 4 sucks powder ash by the through hole 5 of the middle setting of motor 3 output revolving shafts, and water jet 8 water spray minimizing dust generations, improves elimination efficiency high, wipes the sealing strip 7 being equipped with on cover 2 bottom circumference, and prevention powder ash outwards flies upward.
