Description
Affiliated technical field
The utility model relates to a kind of family knife sharpener used in everyday.
Background technology
Existing family knife sharpener used in everyday generally comprises housing, motor, transmission mechanism, emery wheel, polishing wheel and tank.Tank is fixed on the outside of housing, and motor, transmission mechanism are fixed in the housing, and motor links by transmission mechanism and emery wheel and polishing wheel, and emery wheel and polishing wheel lay respectively at the outer both sides of housing, and emery wheel is positioned at the internal upper part of tank.The housing of knife sharpener is made of plastics, and motor is a series excited machine, and transmission mechanism is made up of the level Four gear.Because motor is installed in the housing, motor is a series excited machine, and rotating speed is high, and caloric value is bigger, though motor has cooling fan blade, hot blast circulates in housing, and temperature is higher in the housing, makes housing distortion, causes the knife sharpener cisco unity malfunction.Because transmission mechanism is made up of the level Four gear, so transmission efficiency is low, noise is big.
The utility model content
The technical problems to be solved in the utility model provides a kind of knife sharpener, and not only transmission efficiency height, noise are low for it, and in its housing temperature low, can not make housing distortion,
The technical scheme that its technical problem that solves the utility model adopts is: it comprises housing, motor, transmission mechanism, emery wheel, polishing wheel, tank, motor is fixed in the housing, also comprise wind scooper, this cover is made up of cover body and blast pipe, cover body is fixed on the rear end of motor, the cooling fan blade of motor is positioned at this cover, the fresh air inlet of the blast pipe of this cover and housing base plate is communications and liaison mutually, described transmission mechanism contains main synchronizing wheel, by synchronizing wheel, be with synchronously, countershaft, driving wheel, driven pulley and main shaft, main synchronizing wheel is arranged on the motor shaft, be arranged on the countershaft by synchronizing wheel and driving wheel, countershaft is arranged on the countershaft support of enclosure interior, driven pulley is arranged on the main shaft, main shaft is arranged on the bearing of enclosure interior side, main synchronizing wheel with linked to each other by synchronous band by synchronizing wheel, driving wheel and driven pulley engagement, described motor is an induction machine.
Described in aggregates by synchronizing wheel and driving wheel making.
One end of described countershaft is cut flat.
Set up between reinforcement I, the countershaft support between the motor fixing seat in the described housing on the top and set up reinforcement II.
The root of the slotting pawl of described tank and shell inner surface are roughly on same one side.
Because adopt wind scooper, the cold wind of hull outside enters motor internal and cools off through the blast pipe of this cover, cooled hot blast can't enter motor internal because of the obstruct of wind scooper, discharged by the air outlet of housing base plate, so temperature is low in the housing.Compared with prior art, do not exist hot blast in enclosure interior circulation, make that temperature raises in the housing, cause the situation of housing distortion; Motor adopts induction machine, this motor speed than the series excited machine rotating speed slowly many, caloric value is less, has further reduced the temperature in the housing; Simultaneously also reduced transmission progression, the transmission sound of complete machine is obviously reduced.In aggregates by synchronizing wheel and driving wheel making, make structure compact more, reduce manufacturing cost.One end of countershaft is cut flat, can prevent effectively that countershaft from rotating.Set up between the motor fixing seat on the housing inner top between reinforcement I, the countershaft support and set up reinforcement II, this had both increased the intensity at top, had improved the transmission stability of knife sharpener in running again, had also reduced noise simultaneously.The root of the slotting pawl of tank and shell inner surface roughly on same one side, are improved the intensity of inserting pawl.
