Abstract
The utility model relates to an electric switch for a magnetic control tap, which is composed of a soft magnet (1), a magnetizing winding (2), a jacket tube (3), a spring (4) and a permanent magnet (5). The spring (4) is arranged in the jacket tube (3), the spring (4) is arranged above the permanent magnet (5), the soft magnet (1) is arranged at the outside the jacket tube (3), and the outside of the soft magnet is wound with the magnetizing coil (2). The utility model is exclusively used for a magnetically controlled water tap, the electric control can be realized through the constructional characteristic of the magnetically controlled water tap, and the self water feeding of the magnetically controlled water tap can be realized. The utility model has the advantages of simple structure, easy implementation and safety.
Description
The utility model relates to a kind of electrically switchable grating that is used for the magnetic control water tap.
The construction of switch of magnetic control water tap is to be moved by the upper and lower of handle, drives its outer permanent-magnetic clamp, and by magnetic force, and the interior permanent magnet of control moves up and down realization.In the open and close process, still need to apply mechanical force, applying of mechanical force must touch its handle by staff.The magnetic control water tap can not be realized automatic water-supply, for the higher place of health conditions requiring, remains a shortcoming.
The purpose of this utility model is to provide a kind of electrically switchable grating that the magnetic control water tap is opened and closed automatically.
The utility model is achieved in that this product is made of soft magnet, magnetizing coil, sleeve pipe, spring and permanent magnet, is provided with spring in the sleeve pipe, and spring is above permanent magnet, and sleeve pipe is provided with soft magnet outward, and soft magnet is around with magnetizing coil.
Below in conjunction with drawings and Examples the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a circuit diagram of the present utility model.
The utility model is made of soft magnet (1), magnetizing coil (2), sleeve pipe (3), spring (4) and permanent magnet (5), be provided with spring (4) in the sleeve pipe (3), spring (4) is in the top of permanent magnet (5), sleeve pipe (3) is outer to be provided with soft magnet (1), and soft magnet (1) is around with magnetizing coil (2).
When magnetizing coil (2) fed suitable oriented electric current, soft magnet (1) magnetization produced magnetic force, and this interior permanent magnet of magnetic attraction sleeve pipe (3) (5) makes it to move, and because of permanent magnet (5) initially is the piston that props up water tap, water tap is promptly opened.Disconnect magnetizing coil (2) electric current, soft magnet (1) loss of excitation is under the effect of spring (3), and permanent magnet (5) moves down, and props up the piston of water tap, and water tap is promptly closed.The electric current of control magnetizing coil (2) flows into, and just can finish the open and close process of magnetic control water tap.
In circuit diagram, after the energising, LM567 the 5th pin produces waveform, warp let-off infrared emission tube PH303 emission.When the close water tap of staff, infrared rays is reflected and is received by receiving tube PH302, amplifies loopback by LM741 and gives the LM567 frequency discrimination.Because of frequency is identical, its 8th pin becomes low level by high level, the triode conducting, and electric current flows through magnetizing coil, and water valve is opened.Staff leaves, and infrared reflection disappears, and according to line principle, no current flows through magnetizing coil, and water valve cuts out.
The utility model is exclusively used in magnetic controlling tap, utilizes the self structure characteristics of magnetic controlling tap to realize it being control, makes magnetic controlling tap realize self water feeding; Have simple in structurely, easily implement, the characteristics of safety.
Claims (1)
1, a kind of electrically switchable grating of magnetic control water tap, it is characterized in that it is made of soft magnet (1), magnetizing coil (2), sleeve pipe (3), spring (4) and permanent magnet (5), be provided with spring (4) in the sleeve pipe (3), spring (4) is in the top of permanent magnet (5), sleeve pipe (3) is outer to be provided with soft magnet (1), and soft magnet (1) is around with magnetizing coil (2).
