Abstract
The utility model relates to a chalk dust recoverer, which comprises an opening, a fairing, a six-blade propeller, a motor, a wire, a lithium battery, a recovery bag, a switch and a shell. The chalk dust recoverer is characterized in that the motor is arranged in the shell and fixed onto the inner wall of the shell, the upper portion of the motor is connected with the six-blade propeller, the fairing is arranged above the six-blade propeller, the opening is arranged on the upper portion of the shell, and the recovery bag is arranged on the lower portion of the shell. The lithium battery is arranged on one side of the shell, the shell outside the lithium battery is connected with the shell through a support, the motor is connected with the lithium battery through the wire, and the switch is arranged on the shell outside the lithium battery. Chalk dust is sucked in the recovery bag according to the operating principle that external air pressure is lower than the internal air pressure. The chalk dust recoverer has the advantages of simple structure, convenience in operation and capability of conveniently and rapidly collecting chalk dust on the ground, so that chalk dust is prevented from flying to pollute the air.
Description
Technical field
The utility model relates to a kind of chalk powder recover, is applied to recovery and the cleaning of school student to chalk powder in the classroom.
Background technology
Do not have this type of apparatus in the prior art, teaching general schoolman now also is to use chalk, the word that writes with chalk, and shortcoming is that chalk powder very easily disorderly flies, chalk powder is fallen ground light breeze and is flown upward contaminated environment, and very that cleaning once being with everywhere.
Summary of the invention
The utility model technical problem to be solved is the deficiency that overcomes prior art, and a kind of chalk powder recover is provided, and the utility model solves the technical scheme that its technical problem adopted and is: the structure of the utility model comprises letter road junction, radome fairing, six-bladed propeller, motor, electric wire, lithium battery, collection bag, switch, housing; It is characterized in that being provided with in the housing motor; Motor is fixed on the inwall of housing, is connected with six-bladed propeller above the motor, and radome fairing is set above the six-bladed propeller; The letter road junction is set above the housing; Collection bag is set below the housing, and housing one side is provided with lithium battery, and the outer housing of lithium battery is connected with housing through support; Motor is connected with lithium battery through electric wire, and the outer housing of lithium battery is provided with switch.
Operation principle and operation instruction: the operation principle of the utility model is a principle of utilizing ambient pressure littler than internal gas pressure, thereby chalk powder is sucked in the collection bag.During use, the chalk powder that will clear up is aimed at the letter road junction, opened switch, the driven by motor six-bladed propeller rotates, and six-bladed propeller rotates, and makes air pressure inside reduce through radome fairing, thereby chalk powder is absorbed in the collection bag.Collection bag is split type the connection with housing, after absorption finishes, collection bag is taken off from housing, is convenient to the cleaning to chalk powder in the collection bag like this.
The beneficial effect of the utility model is that the utility model is simple in structure, and is easy to operate, can conveniently chalk powder on the ground be collected, thereby prevent that chalk powder from disorderly flying and contaminated air.
Description of drawings
Fig. 1: the utility model example structure sketch map;
Among the figure: letter road junction 1, radome fairing 2, six-bladed propeller 3, motor 4, electric wire 5, lithium battery 6, collection bag 7, switch 8, housing 9.
The specific embodiment
Concrete detailed description below with reference to description of drawings the utility model being done.Shown in accompanying drawing, the structure of the utility model comprises letter road junction 1, radome fairing 2, six-bladed propeller 3, motor 4, electric wire 5, lithium battery 6, collection bag 7, switch 8, housing 9, it is characterized in that being provided with in the housing 9 motor 4; Motor 4 is fixed on the inwall of housing 9, is connected with six-bladed propeller 3 above the motor 4, and radome fairing 2 is set above the six-bladed propeller 3; Letter road junction 1 is set above the housing 9; Collection bag 7 is set below the housing 9, and housing 9 one sides are provided with lithium battery 6, and lithium battery 6 outer housings are connected with housing 9 through support; Motor 4 is connected with lithium battery 6 through electric wire 5, and lithium battery 6 outer housings are provided with switch 8.
Embodiment recited above describes the preferred implementation of the utility model; Be not that design and scope to the utility model limits; Under the prerequisite that does not break away from the utility model design concept, common engineers and technicians make the technical scheme of the utility model in this area various modification and improvement all should fall into the protection domain of the utility model; The technology contents that the utility model is asked for protection all is documented in claims.
