Description
Technical field
Underwater switch and its application product are the utility model is related to, switch especially for motor and application its technology
Dust catcher, specifically motor enter water starting switch and enter the dust catcher of water starting switch using motor.
Background technology
In the prior art, some underwater installations are suitably opened under water, and are closed when leaving the water surface, so being not suitable for setting
Put hand switch, such as underwater duster.
Underwater cleaning equipment is divided into two kinds, and one kind is that motor is located on the bank, and only cleaning head gos deep into water, this cleaning
The main frame of equipment does not contact directly with water, to the less demanding of liquid sealing protection；Another underwater cleaning equipment is then a kind of complete
The dust catcher of equipment immersion, its motor is usually constructed with perfect liquid-tight envelope safeguard measure, particularly on the output shaft of motor
Seal can be nested with, is furthermore provided with a hand switch to control the startup of dust catcher and closing, in use, first opening
Close, starting device, operate motor, finally dust catcher is put into water and carried out the work.
But prior art has individual problem to be never resolved, that is,：The seal being nested with output shaft is easy
Damage, loses good sealing effectiveness.It has been investigated that the damage of seal is entering water front motor mainly due to dust catcher
Output shaft can not distribute in time with seal frictional heat, so as to cause the deformation of seal and aging.After dust catcher starts
The time shelved on the coast is more long, then damage of the output shaft to seal is bigger.
The screen pack of underwater duster has two kinds of assembly methods：A kind of a kind of such as documents " new-type pool cleaner ",
