Abstract

The utility model provides an electric mop. The electric mop comprises a main engine and a mop head, wherein the main engine is provided with a handle, and the mop head is located below the main engine and hinged to the main engine. Two scrubbing plates are arranged on the bottom surface of the mop head. Guide rails used for the scrubbing plates to move left and right are arranged on the mop head. A rotating shaft is installed between the two scrubbing plates. A micromotor which drives the rotating shaft directly or indirectly is installed in the mop head. The rotating shaft is sleeved with a crank shaft. The crank shaft comprises an upper eccentric wafer and a lower eccentric wafer, wherein the upper eccentric wafer and the lower eccentric wafer are partly overlapped. A connecting piece is arranged in each scrubbing plate, wherein a connecting rod is installed between the connecting piece and the crank shaft, one end of the connecting rod is hinged to the connecting piece, and the other end of the connecting rod is hinged to the corresponding eccentric wafer on the crank shaft. According to the electric mop, the transmission between the crank shaft and the connecting rods is used for driving the two scrubbing plates to move in a reciprocating mode so as to scrub and clean the floor, therefore, the structure of the mop head part is simplified, and the noise at the time when the mop head works is greatly lowered. The electric mop has the advantages of being simple in structure, convenient to operate, good in floor cleaning effect, and long in service life, thereby having a bright market prospect.

Description

Blackboard eraser electrically

Technical field

The utility model relates to a kind of electrical equipment for cleaning, the specifically a kind of electrically blackboard eraser that can clean, clean ground.

Background technology

At present mainly still utilize floor mop or wiper for the cleaning on floor, sweep a room and will waste a large amount of time.Occur a kind of electrically blackboard eraser on the market, light, time saving and energy saving and low energy consumption is favored by the user deeply because of its use for this reason.Although its appearance has solved the fatigue on cleaning floor to people, also exist inevitably some amendatory shortcomings and weakened its attraction to the user.At first, this floor cleaner brush be with a micro machine as power source, transmit kinetic energy by a pair of gear reduction and with synchronous belt, two gears that are connected with bent axle are turned round simultaneously.Each bent axle drives a connecting rod separately simultaneously, and connecting rod affects the connector that is installed on the wiping board, and two wiping boards that smear are made the function that symmetrical round rectilinear motion is finished to wash the floor at the guide rail of setting with making.Be to make of engineering plastics in order to save its gear of cost, it is exactly main noise source.Because plastics are different from metal, it can not do very accurately, the gear that especially smears, because the power of carrying is larger, so design thicklyer, the twisting between them can not be very accurate, easily produces annoying noise during running.On the other hand, synchronous belt can rub because running up when interlock motor gear and crankshaft toothed wheel and produce high temperature, and produces judder in the transmission process, very easily is worn and pulls apart, thereby affect its service life.Disclosed on May 16th, 2012 such as Patent Office of the People's Republic of China, the patent No. is " the wiping ground equipment " of " ZL201120166668.5 ", and it at first will be equipped with a wiping domain of wiping ground equipment, is equivalent to ground of the present utility model rubbing head.Wiping the domain partly is comprised of the mortise of wiping ground roller, gear, miniature motor, Sheng cleaning agent, permanent plant dish etc.Wipe the ground roller and divide soft wiping ground roller, rigid wiping ground roller.Soft wiping ground roller is used for wiping the dirt that wipe easily on ground.Its effect is as dragging handkerchief.Rigid wiping ground roller is not absolute hard, but more soft wiping ground roller is hard.Can be made by plastics, chemical materials etc.It is mainly used in wiping the dirt that ground is not easy to wipe.Be to be equipped with a mortise of containing cleaning agent above the permanent plant dish wiping above the wiping ground roller of domain than front end.Secondly, be equipped with a handle of wiping ground equipment.Just there is defects in this equipment.

The utility model content

The purpose of this utility model is for the defective of above-mentioned prior art and deficiency, for people provide that a kind of noise is low, long service life, electrically blackboard eraser easy and simple to handle.

Technical solution adopted in the utility model is for achieving the above object: this is blackboard eraser electrically, it comprises with the main frame of handle and is positioned at the main frame below ground rubbing head hinged with main frame, the bottom surface of described ground rubbing head is provided with two wiping boards, is provided with the guide rail that supplies the wiping board move left and right in the ground rubbing head; Between two wiping boards rotating shaft is installed, the micro machine of direct or indirect drive shaft is installed in the ground rubbing head, be set with bent axle in the described rotating shaft, this bent axle comprises upper and lower two partly overlapping eccentric disks; Be respectively arranged with connector in every wiping board, between connector and the bent axle connecting rod be installed, an end and the connector of this connecting rod are hinged, the corresponding eccentric disk twisting on the other end and the bent axle.

Described micro machine is by reduction gear box rear drive rotating shaft.

Described micro machine, reduction gear box and rotating shaft are positioned at same axis, and vertical with the ground rubbing head.

Described rotating shaft and bent axle are for being in transmission connection, and the axle center of rotating shaft is positioned at the center of bent axle two eccentric disk laps.

Described connecting rod is being embedded with bearing, the inner circle that the eccentric disk embedded axle of bent axle holds near in the end of bent axle.

The utility model drives two wiping boards and moves back and forth by the transmission of crankshaft-and-connecting-rod, realizes scouring, cleaning to ground, has simple in structure, easy to operate, cleanly effective advantage.And it has simplified the structure of ground rubbing head part, compare in the market ground rubbing head, save the bearing of plastic gear and rotating shaft twisting and the transmission synchronous belt of micro machine and two wiping board gears, reduced the vibration of ground rubbing head, the noise when greatly reducing ground rubbing head work.And owing to the part of the easy wearing and tearing such as plastic gear, longer service life have been omitted.
