Embodiment
Below against accompanying drawing, by the description to embodiment, the embodiment to the present invention makees further details of
Explanation.
Level sensor core assembly structure of the present invention, as shown in Fig. 1,2, magnetic core 4 passes through magnetic core support 3 and magnetic core cap 5
Fixed support, magnetic core support 3 includes the stud for the pallet and protrusion fitted with upper end membrane contacts, and magnetic core 4 is placed on stud, magnetic core
Cap 5 is fixedly connected in stud to support the lower end of magnetic core 4.Magnetic core cap 5 is connected with magnetic core support 3 by riveted.Magnetic core cap 5 and stud
The side wall circumference of riveting is coordinated to be provided with the stupefied bar of anti-rotation.As shown in Figure 2, magnetic core cap 5 is provided with coordinates riveting with stud in magnetic core support 3
The column structure connect, during installation, the column structure is enclosed in stud, realizes that nested type is riveted.Using two plastics push rods of use
Riveted carry out fixed magnetic core, convenience quick for installation and stability is good, while stupefied provided with anti-rotation on the column structure side wall of magnetic core cap 5
Bar extends its service life preferably to ensure that mounting structure is stable.
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 install constitute shell structure base 12, air inlet end cap 1 with
Provided with the barrier film 2 that shell structure is divided into two cavitys between base 12, air inlet end cap 1 is provided with entering for being connected with upper cavity
LC oscillating circuits are provided with valve, lower chamber, the hub of a spool of magnetic core 4 through LC oscillating circuits is moved with barrier film.During work, every
Film 2 is moved magnetic core by zone of pressure and moved up and down in the coil of LC oscillating circuits, and moving up and down for composite cores changes coil
Inductance value, the change of inductance value changes into frequency signal and 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 sends 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
The plug wire terminal 7 being connected with electric capacity 9 is plugged with ring framework 8, base 12 is provided with the interface for stretching out plug wire terminal 7.This hair
Bright middle base 12 is integral type cavity body structure, and injection molding can be set LC oscillating circuits, simplify structure, eliminate peace
Step is filled, the stability of product is improved, greatly ensure that the validity and uniformity of level sensor performance.
The body of coil rack 8 is hollow columnar structured, and protrusion is equipped with spacing branch in the upper and lower ends of body
Support the extension of enamel-covered wire 6, stable support enamel-covered wire 6.The lower section of coil rack 8 is additionally provided with towards inserting that interface direction is protruded
Block, inserted block is provided with the slot of correspondence grafting plug wire terminal 7.Plug wire terminal 7 is plugged in slot from inside to outside, in plug wire terminal
