Electromagnetic drainer and drain method thereof

Abstract

The invention discloses an electromagnetic drainer, which comprises a drain pipe and a control unit, wherein the control unit comprises a magnetic field generating device sleeved outside the drain pipe and used for generating a magnetic field, and a sliding unit capable of sliding in the drain pipe vertically; the sliding unit comprises a connecting frame, two magnets arranged on the upper and lower parts of the connecting frame and a sealing unit sleeved with the connecting frame and matching the drain pipe; the magnets corresponds upper and lower ends of the magnetic field generating deviceand the electric field generating device generates magnetic field acting force which applies to the upper and lower magnets in the same direction; and the sealing unit selectively seals or switch on the end port of the drain pipe under the magnetic field acting force along the polarity change of the magnetic field generating device and the two magnets. The drainer is attractive in appearance, compact in structural matching, and more sensitive in work.

Description

technical field [0001] The invention relates to an electromagnetic drainer and a draining method thereof. Background technique [0002] Existing drains currently on the market use the principle of magnetic force, but they seldom use the principle of electromagnetic drive, such as the utility model patent of "Magnetic Automatic Opening and Closing Drain", which uses Two magnets with opposite N poles are used to make the valve seat close the drainage channel. When the weight of the drainage and the weight of the valve seat are greater than the repulsive force, the valve seat opens to drain water. Although it also uses the principle of magnetic force to realize the function of automatic opening and closing of drainage, but in actual use, because the size of the drainage weight cannot be estimated, it will also be difficult to set the magnetic force value that cooperates with it, making the water fall device The opening and closing is not sensitive, which affects the use effect...
