Description
Technical Field
[0001] The utility model relates to the technical field of water purification equipment, in particular to an intelligent pre-filter provided with a motor. Background Art
[0002] At present, the sewage outlet of the pre-filter mainly adopts two forms: a ball valve or a sewage shaft, which are respectively a method of connecting the sewage outlet to a ball valve and a method of combining the sewage outlet with a sewage shaft and a filter bottle structure.
[0003] The ways of connecting the drain port to the ball valve mainly include manual draining and electric draining. When draining manually, the ball valve is manually rotated to open the drain port to drain the sewage. However, when manually opening the drain port to drain the sewage, the sewage may be forgotten during use, resulting in more foreign particles adhering to the filter screen during actual use, which reduces the flow rate and affects the user experience. When draining electrically, the ball valve is driven by a motor through the setting of the circuit board time, and the sewage is drained after the ball valve is opened. However, the cost of the ball valve is relatively high, and the ball valve itself has a certain length and volume. Coupled with the structure of the motor, the size of the product is large, which is not conducive to subsequent installation.
[0004] There are two ways to coordinate the sewage outlet with the sewage shaft and the filter bottle structure: one is to manually rotate the sewage shaft seat to realize the rise or fall of the sewage shaft, but the manual opening of the sewage discharge will forget to discharge sewage regularly during use, resulting in more foreign particles adhering to the filter screen during actual use, which reduces the flow rate and affects the user experience; the other is to drive the sewage shaft with a motor to rise or fall to discharge sewage, but the direct contact area between the motor and the sewage shaft is small, and the torque of the motor is small. When the structure between the sewage shaft and the filter bottle fails or the O-ring is stuck, the motor and the sewage shaft will slip, and it cannot be switched from the sewage discharge state to the filtering state, causing the filter to leak. Utility Model Content
