[0033] When the water level changes, the surface of the water level sensor body 1 will be cleaned. The specific operation is as follows:

[0034] When the water level rises, the water drives the floating plate 219 to drive the rack 218 to move upward, so that the rack 218 touches the second gear 211, drives the second rotating shaft 212 and the second fan 214 to rotate, generates air flow, and allows air to enter from the air inlet 203, so that the dirt attached to the top of the water level sensor body 1 can enter from the air inlet 203, and is blocked by the filter 205 and the sponge 206, and the filtered wind flow is discharged from the air outlet 204, and can continue to blow the water level sensor body 1, so that the dirt is blown into the air inlet 203, thereby improving the dirt collection capacity. When the water level drops, under the action of gravity, the rack 218 and the floating plate 219 move downward, so that the fixing rod 3109 and The first guide rod 3107 moves downward, thereby causing the first connecting plate 3105 to move downward. Since the first connecting plate 3105 is connected to the first baffle plate 3101 in a fixed connection, the first baffle plate 3101 moves downward. After the edge of the first baffle plate 3101 contacts the edge of the second baffle plate 3104, the first baffle plate 3101 is elastically blocked by the elastic rubber pad 3103. The weight of the first connecting plate 3105 and the second connecting plate 3201 is not enough to press the elastic rubber pad 3103, so that when the rack 218 moves downward, it drives the first guide rod 3107 and the fixed rod 3109 to move toward the air inlet 203 along the trajectory of the guide groove 3106. When the rack 218 moves downward, The guide hole 3202 is shaped like a "<" and the inner side of the guide hole 3202 fits the outer side of the second guide rod 3203, so that when the second guide rod 3203 moves downward, it will move backward and then forward, preventing the rack 218 from driving the second fan 214 to rotate in the opposite direction when moving toward the air inlet 203, thereby generating a reverse wind flow to blow the dirt out of the air duct 202. When the first guide rod 3107 moves to the lower end of the guide groove 3106, the rack 218 and the first guide rod 3107 both move a distance toward the air inlet 203, so that the rack 218 drives the first gear 210 to rotate in the opposite direction, so that the first fan 214 is The fan 209 rotates in the opposite direction. Since the direction of the blades of the first fan 209 is opposite to the direction of the blades of the second fan 214, the direction of the airflow generated by the reverse rotation of the first fan 209 is consistent with the direction of the airflow generated by the forward rotation of the second fan 214. When the first guide rod 3107 moves to the lower end of the guide groove 3106, the rack 218 continues to move downward on the floating plate 219, and its force is all concentrated on the top of the first connecting plate 3105, which can drive the first baffle 3101 to squeeze the second baffle 3104, so that the rack 218 can continue to move downward. In summary, the surface cleaning of the water level sensor body 1 does not need to rely on additional electricity to drive, which saves energy, and the water level sensor body 1 can be cleaned when the water level rises and falls.
