In the initial state, the cleaning piston 14 is positioned at the lowermost side, the cleaning plate 32 is positioned at the foremost side, the square piece 26 is positioned at the foremost side, the second rotating shaft 22 and the third rotating shaft 75 are not connected, the motor 21 is positioned at the rearmost side, the fourth rotating shaft 56 is connected with the fifth rotating shaft 59, the slider 52 is positioned at the foremost side under the elastic force of the second spring 51, the second bearing 53 is attracted by the permanent magnet 48, and the sixth rotating shaft 61 is positioned at the uppermost side.

When scale needs to be removed, the water outlet 43 is opened, the water inlet 20 is closed, the motor 21 is started, the second rotating shaft 22 rotates, the second chain wheel 35 rotates and drives the chain 45 to rotate, the first chain wheel 57 rotates, the fourth rotating shaft 56 rotates and drives the fifth rotating shaft 59 to rotate, the rope wheel 58 rotates and contracts the first pull rope 15, the cleaning piston 14 is pulled upwards and cleans the cavity wall of the cavity 16, the scale is gradually pushed into the water storage cavity 18, meanwhile, the first pull rope 15 is cleaned by the friction pad 76 when passing through the friction pad 76, when the cleaning piston 14 moves to the uppermost side and is in contact with the friction pad 76, the first pull rope 15 is tensioned and cannot be continuously contracted, the force on the first pull rope 15 is increased, the first pull rope 15 generates downward pressure on the pulley 60, the sixth rotating shaft 61 is pressed downward, and the second bearing 53 is separated from the adsorption state of the permanent magnet 48, the sixth rotating shaft 61 and the second bearing 53 move downwards, the second pull rope 49 is pulled, the sliding block 52 moves backwards under the pulling force of the second pull rope 49, the fourth rotating shaft 56 moves backwards, the fourth rotating shaft 56 is disconnected from the fifth rotating shaft 59, and the fifth rotating shaft 59 has large torque but is limited from reversely rotating under the action of the clamping rod 65 and the ratchet 66; when the sliding block 52 moves backwards, the third pulling rope 71 is loosened, and then the motor 21 moves forwards under the elastic force of the first spring 73, and then the second rotating shaft 22 is connected with the third rotating shaft 75, and then the second rotating shaft 22 drives the third rotating shaft 75 to rotate, because the square piece 26 and the fixed plate 25 are limited by the power cavity 24 to rotate, under the rotation of the third rotating shaft 75 and the threaded section 33, the square piece 26 and the fixed plate 25 move backwards, and then the cleaning plate 32 is driven to move backwards through the moving block 77, the first bearing 30 and the first rotating shaft 31; meanwhile, the second rotating shaft 22 rotates to drive the first gear 46 to rotate, further the second gear 47 rotates, further the square shaft 34 rotates, further the second belt wheel 68 rotates, further the first belt wheel 28 rotates through the belt 27, further the rotating shaft 29 rotates, further the first rotating shaft 31 rotates and drives the cleaning plate 32 to rotate, therefore, the cleaning plate 32 moves backwards while rotating axially, and cleans the inner wall of the water storage cavity 18, and further the scale is pushed to the rear side; when the cleaning pad 79 contacts the heating plate 42, the square will move to the rearmost end of the threaded section 33, at which point the cleaning plate 32 will not move backwards, but the cleaning pad 79 and cleaning plate 32 will continue to rotate and rub against the heating plate 42; after the cleaning is finished, the motor 21 is reversed, the cleaning plate 32 moves forwards until the water inlet 20 is exposed, at the moment, the water inlet 20 and the water outlet 43 are opened, the accumulated scale can be discharged at one time, then the water inlet 20 and the water outlet 43 are closed again, and the cleaning plate 32 moves to the foremost side;

meanwhile, the second bearing 53 and the sixth rotating shaft 61 move up under the elastic force of the third spring 55, the second bearing 53 is adsorbed by the permanent magnet 48 again, the second pull rope 49 is loosened, the fourth rotating shaft 56 moves forward under the elastic force of the slider 52 and the second spring 51 and is connected with the fifth rotating shaft 59 again, the third pull rope 71 is tensioned again, the motor 21 moves backward under the tensile force of the third pull rope 71, and the second rotating shaft 22 is disconnected from the third rotating shaft 75, so that the initial state is returned; because the water storage cavity 18 is communicated with the power cavity 24, the water level in the water storage cavity 18 cannot be too high, when the water level in the water storage cavity 18 is too high and contacts the conducting strip 37, the circuit of the electric wire 36 is switched on, the second electromagnet 38 is electrified, the second electromagnet 38 obtains magnetism and repels the blocking rod 41, the water inlet 20 is blocked, the water level is placed to continuously rise, when the water level is lowered, the second electromagnet 38 is powered off, and the blocking rod 41 moves forwards under the pulling force of the fifth spring 40 and opens the water inlet 20.

The invention has the beneficial effects that: the incrustation scale is carried out getting rid of to vacuum tube, water storage chamber, hot plate that can be very light, then open the delivery port carry on the blowdown can, can also resume original state after finishing driving away, can repeat repetitious usage, no longer need demolish the washing to traditional water heater, the operation is very simple, low in labor strength, also do not have the risk of damaging the water heater when wasing simultaneously, abluent effect is also relatively better, is worth promoting.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
