[background technology]
It is no matter wall plaster or in lacquering technique, all need to carry out the polishing program, stir up a cloud of dust in order to prevent from polishing, existing sander such as application number are that 92223866.9 Chinese utility model patents are disclosed, the parts of polishing have been connected on vacuum cleaner, during practical operation, by the hand-held polishing parts of workman, the sander parts are connected flexible pipe and are connected with vacuum cleaner, and are like this siphon away dust by vacuum cleaner in polishing.Flying dust problem when the Integral design of this sander and vacuum cleaner can effectively solve the plane polishing, but the switch of hand-held polishing parts and vacuum cleaner are substeps to be started or closes, if the workman is when carrying out polishing operation like this, if it is upper cumbersome from must distantly not only operating to leave vacuum cleaner, and can waste many electric energy.Simultaneously, the motor speed of the vacuum cleaner of existing dustless sander is uncontrollable, regardless of metope soft or hard degree, degree of roughness how, the power output of vacuum cleaner is all identical, this indiscriminate power stage is not only wasted electric energy, and the vacuum cleaner noise of working in high-power situation is also larger.
[utility model content]
The purpose of this utility model is to provide a kind of polishing parts and synchronously start or stop of vacuum cleaner, and the adjustable dustless sander of vacuum cleaner motor speed, and vacuum cleaner can use as the speed governing vacuum cleaner separately.
The technical solution of the utility model is as follows: a kind of dustless sander, comprise vacuum cleaner and sander, described sander is provided with dust cover, dust cover is provided with the gas outlet, connecting hose between described dust cover gas outlet and vacuum cleaner, described vacuum cleaner is provided with a three-pin socket, and described sander is provided with the three-pin plug of socket on a connection vacuum cleaner, described three-pin socket has connected the vacuum cleaner circuit, and described three-pin plug has connected the sander circuit;
Described vacuum cleaner circuit comprises a double-point double-throw switch, a relay and vacuum cleaner motor, three pin of described three-pin socket are respectively N, L, S, one end of double-point double-throw switch connects respectively N and L pin, the other end connects the vacuum cleaner motor, relay coil connects respectively S and N pin, and normal the battle connects the L pin;
Described sander circuit comprises a double-pole single throw and sander motor, three pin of described three-pin plug are respectively L ', N ', the S ' corresponding with three pin of three-pin socket, motor connects respectively L ', N ' pin and has connected double-pole single throw, and S ' pin and L ' pin are connected to two terminals of one of them switch in double-pole single throw.
connected the alternating current of 220 volts on double-point double-throw switch, when three-pin plug inserts three-pin socket, closed double-pole single throw, S ' pin L ' pin short circuit, S pin and L pin be short circuit also, if during the downward closure of double-point double-throw switch this moment, the sander motor is powered, relay is also powered simultaneously, relay adhesive this moment, make the vacuum cleaner electrical power, so can start sander and vacuum cleaner by double-pole single throw, otherwise, the sander motor outage if double-pole single throw disconnects, relay also cuts off the power supply simultaneously, recover normally off, the vacuum cleaner motor quits work.When double-point double-throw switch was upwards closed, vacuum cleaner used separately and speed governing.
Connect mill on described sander machine shaft, described dust cover is enclosed within on sander motor and mill.Dust cover covers the sander outside, prevents that not only dust from disorderly flying, and can also provide dust suction required sealing condition to vacuum cleaner.
Described vacuum cleaner circuit is provided with electrically-actuated throttle device.Described vacuum cleaner comprises a housing, and housing is provided with the adjusting knob that has connected electrically-actuated throttle device.The electrically-actuated throttle device of vacuum cleaner electronics can be regulated the power output of vacuum cleaner motor, satisfies the different capacity demand under different polishing conditions, has saved electric energy, has avoided unnecessary noise, by the adjusting knob handled easily.
Compared with prior art, outstanding advantages of the present utility model is: sander is connected circuit and is connected with three-pin plug by three-pin socket with vacuum cleaner, switch on sander is controlled the start or stop of vacuum cleaner motor by the mode of controlling the relay on the vacuum cleaner circuit, so realize the synchronous Push And Release of sander and vacuum cleaner.Double-point double-throw switch on the vacuum cleaner circuit makes vacuum cleaner namely can work asynchronously with sander, also can work independently.The vacuum cleaner motor arranges electrically-actuated throttle device, satisfies the different capacity demand under different polishing conditions, and energy-conserving and environment-protective reduce noise.
