The top of the settling cup 1 is threaded and screwed up at the bottom of the settling cup 1.
When the filter works, the high water level probe 4 and the low water level probe 5 continuously send water level signals to the electric control device 6. The electric control device 6 is connected with the vehicle-mounted ECU through a vehicle-mounted circuit. The water discharge action can be controlled by the electric control device 6 or an on-board ECU for different vehicle types.
The water separated during the operation of the filter is continuously accumulated in the sedimentation cup 1. When the water level in the sedimentation cup 1 is lower than the preset water level (high water level probe 4), under the elastic action of the inner spring 28 and the outer spring 21, the water path sealing plate 19 downwards compresses the top end of the water cylinder 13 to seal the water cylinder 13, and meanwhile, the air path sealing plate 22 downwards compresses the top end of the vent hole 20 to seal the vent hole 20, at the moment, the air path is blocked by the air path sealing plate 22, the water path is blocked by the water path sealing plate 19, air can not be fed into the valve body 9, and the drain pipe 7 can not drain water downwards.
When the water level in the sedimentation cup 1 reaches a preset water discharge level (a high water level probe 4), the electric control device 6 or the vehicle-mounted ECU enables the coil 11 of the water discharge electromagnetic valve 3 to be electrified according to a signal of the high water level probe 4, the coil 11 drives the movable iron core 15 to move upwards after being electrified, and the movable iron core 15 drives the central connecting rod 18 to move upwards. When the center link 18 moves upward, the step 27 of the center link 18 compresses the inner spring 28 upward while the compression deformation amount of the waterway sealing plate 19 is gradually reduced. Since Y-X is larger than or equal to 0.3 mm, before the waterway sealing plate 19 is separated upwards from the water passing cylinder 13, the waterway sealing plate 19 drives the air passage sealing plate 22 upwards to be separated from the vent hole 20 through the force transmission sleeve 29, after the vent hole 20 is opened, the waterway sealing plate 19 is separated upwards from the water passing cylinder 13 after the compression deformation of the waterway sealing plate 19 is completely recovered along with the further lifting of the central connecting rod 18, and the waterway is opened. At the moment, the outside air enters the valve body 9 above the water passing cylinder 13 through the water passing holes and further enters the sedimentation cup 1 through the top cover water passing groove 25 upwards; meanwhile, water in the sedimentation cup 1 continuously downwards enters the cavity 10 in the valve body 9 through the water passing groove 25 of the top cover and then enters the water passing cylinder 13; the water in the water passing cylinder 13 enters the drain pipe 7 downwards through the static iron core water trough 16 and the movable iron core water trough 17 and is discharged out of the valve body 9, and the water level in the sedimentation cup 1 continuously drops. When the water level in the sedimentation cup 1 is reduced to the water level at which water discharge is finished, the low water level probe 5 sends a signal that the water level in the sedimentation cup 1 is reduced to the water level at which water discharge is finished to the electric control device 6, the electric control device 6 or the vehicle-mounted ECU control coil 11 is powered off, and the waterway sealing plate 19 and the waterway sealing plate 22 are both restored to the original valve closing state under the action of the inner spring 28 and the outer spring 21.
The above embodiments are only used for illustrating but not limiting the technical solutions of the present invention, and although the present invention is described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: the present invention may be modified or substituted with equivalents without departing from the spirit and scope of the invention, which should be construed as being limited only by the claims.
