Stud coordinates the side wall circumference of riveting to be provided with the stupefied bar of anti-rotation.As shown in Figure 2, magnetic core cap 5 is provided with and matched somebody with somebody with stud in magnetic core support 3
The column structure of riveting is closed, during installation, the column structure is enclosed in stud, realizes that nested type rivets.Using two plastics of use
The riveted of push rod carrys out fixed magnetic core, convenience quick for installation and stability is good, while is provided with the column structure side wall of magnetic core cap 5 anti-
Turn stupefied bar preferably to ensure that mounting structure is stable, extend its service life.
The lower end of magnetic core cap 5 is provided with back-moving spring 11, and back-moving spring 11 is placed in base 12, and lower end is provided with and the screw thread of base 12
The nut 13 of connection.Back-moving spring 11 is pressed on magnetic core cap 5 by nut 13, so that barrier film 2 resets.
Level sensor include air inlet end cap 1 and with its coordinate installation form shell structure base 12, air inlet end cap 1 with
The barrier film 2 that shell structure is divided into two cavitys is provided between base 12, air inlet end cap 1 enters provided with what is connected with upper cavity
Valve, lower chamber is interior to be provided with LC oscillating circuits, and the hub of a spool of magnetic core 4 through LC oscillating circuits moves with barrier film.During work, every
Film 2 is moved magnetic core in the coil of LC oscillating circuits by zone of pressure and moved up and down, and moving up and down for composite cores, changes coil
Inductance value, the change of inductance value change into frequency signal and are sent into after the starting of oscillation of LC oscillating circuits and amplifying circuit processing
Single-chip microcomputer carries out inter-process, and resulting frequency signal is sent into washing machine, the drive module of dish-washing machine computer board, to reach control
Water level height in washing machine processed, dishwasher into operation room.
Wherein LC oscillating circuits include the coil rack 8 being placed in base 12, and enamel-covered wire 6 is around in the outside of coil rack 8.Line
