Description
The utility model relates to the improvement of dehumidifier controlling organization, specifically is a kind of humidity inductive switch, and it belongs to family expenses humidity controller technical field.
In the prior art, humidity control is one always and is difficult to deal with problems.Existing dehumidifier does not mostly have humidity conditioner.What have has a humidity controller, then is complex structure, involves great expense, and only be adapted to the humidity control of large space, and the regulating and controlling precision is not high, insensitive to humidity inductive.So far not being suitable for family's cubicle humidity automatic controller comes out.
The purpose of this utility model is the humidity inductive switch that a kind of family expenses dehumidifier will be provided.Employing is made the induction sensitivity, the humidity inductive switch of reliable in action to the film of humidity inductive sensitivity.This construction of switch is wanted rationally to be active in one's movements, and the degree of regulation height is adapted to small-sized household dehumidifier automatic control process automatically.
Task of the present utility model is finished by following technical scheme, developed a kind of humidity inductive switch, it comprises: the bar trough-shaped housing, be installed in the sensitive switch in this housing notch, these housing two ends above this switch resilient contact are provided with respectively by wearing the support film lever that the shell hinge fixes, and a power rod end axle of two these levers is bound up on respectively on the two ends of humidity inductive film; Being in this switch top support film lever is the lever of inverted "L" shaped, and the horizontal pressure stock of the other end of this lever extends through and presses and touches on the sensitive switch resilient contact; The support film lever that is in this switch next door is linked with an extension spring with its other end bar plate, and the other end of this spring is hung solid in the hole clipping in this housing one side shell wall stage casing, and this extension spring power constitutes the initial tension of this film flattening between two these levers; Other end bar plate end at this lever that hangs with extension spring is provided with the preset screw, and this screw can lean in the humidity of adjusting knob and set on the cam, and the swing handle pedestal of this knob is located on the both sides shell wall of this housing.
Described adjusting knob, also position-limited wheel can be set on its swing handle axle, this is taken turns to being raised in the sectional wheel of this axial plane, this is taken turns and is arranged on the next door that humidity is set cam, and can touch the end of horizontal pressure stock, this is taken turns with adjusting knob and rotates, or be in this stock above, or be in this stock below, on this housing one side shell wall, also be provided with the spacing card that prevents degree of moving past on this stock.
Described humidity is set cam, its wheel shape gabarit or be involute shape profile, or be spiral of Archimedes shape profile, or the ovalize profile.
The advantage of humidity inductive switch of the present utility model has: (1) is rational in infrastructure, the movement response sensitivity.This switch utilizes a kind of imbibition, and the plastic film that dehydration is shunk by two cover leverages, is converted into the change in displacement that fine motion has resilient contact with the tension variation of film, thereby realizes opening or closing of sensitive switch.(2) parts are provided with compactness, and volume is little, and control procedure is simple and practical.Because the dibit leverage that adopts film to connect, the control that existing sensitive switch is carried out or opens or closes, and the adjusting knob of manual setting humidity is arranged, and just can realize the degree of regulation height, handoff procedure is easy, and the humidity that adapts to small-sized dehumidifier is controlled.
Embodiment of the present utility model further describes as follows in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of humidity inductive switch.
Fig. 2 is the adjusting knob structural representation (A of Fig. 1 is to view) of humidity inductive switch.
Use this humidity inductive switch referring to the AHD-25 type dehumidifier that Fig. 1,2 makes.This switch comprises: bar trough-shaped housing 1 is installed in the sensitive switch 2 in this housing 1 notch.Housing 1 two ends above these switch 2 resilient contacts 3 are provided with respectively by wearing the support film lever that shell hinge 4,5 fixes.One power bar 6 of two these levers and 7 end axles 6 ' and 7 ' respectively be bound up on the two ends of humidity inductive film 14.The support film lever that is in these switch 2 tops is the lever that is inverted "L" shaped, and the horizontal pressure stock 8 of the other end of this lever extends through and presses and touches on this switch 2 resilient contacts 3.The support film lever that is in these switch 2 next doors is linked with an extension spring 11 with its other end bar plate 10.The other end of this spring 11 is hung solid in the hole clipping 12 in these housing 1 one side shell wall stage casings.This extension spring power constitutes the initial tension that this film 14 flattens between two these levers.End at the other end bar plate 10 of this lever that hangs with extension spring 11 is provided with preset screw 9.This screw 9 can lean in the humidity of adjusting knob 18 and set on the cam 15.The swing handle axle 16 of this knob 18 is erected on the both sides shell wall of this housing 1.Destroy the whole sensitivity of set mechanism in order to prevent adjusting knob 18 from excessively rotating, on the swing handle axle 16 of this knob 18, also set up position-limited wheel 17.This takes turns 17 is the sectional wheels that are raised in this 16 axial plane.This is taken turns 17 and is arranged on the next door that humidity is set cam 15, and can touch the end of horizontal pressure stock 8.This take turns 17 with adjusting knob 18 rotate or be in this stock 8 above, or be in this stock 8 below.When this take turns 17 be in this stock 8 below the time, can more than lift this stock 8 and leave resilient contact 3, on these housing 1 one side shell walls, also be provided with the spacing card 13 of degree of moving past on the horizontal pressure stock 8, prevent to move on this stock 8 excessively, as long as leave resilient contact 3.These two extreme positions that position-limited wheel 17 is provided with, the normal pass of sensitive switch 2 just, the operating state of often opening.
The designed humidity of this switch is set cam 15, and its wheel shape gabarit is involute shape profile.This takes turns 15 when leaning with preset screw 9, can change the extension spring power of extension spring 11, and lever system is deflected, thereby changes the tension force of this film 14.This film 14 tension force size just can be set by this screw 9 and involute heart cam 15.Also can to drive the horizontal pressure stock of the lever of inverted "L" shaped be axle and mobile deflection with its hinge 4 to these film 14 tension force simultaneously.In set the lever system that these film 14 tension force under a certain humidity involve by this screw 9 and this cam 15; when air humidity is reduced to this setting humidity; this film 14 shrinks; it can only drive the inverted "L" shaped lever and deflect down; make this stock 8 press down mobile; pressure touch micro switch 2 resilient contacts 3 make its action close dehumidifier, make its shutdown.When air humidity increases to this setting humidity, these film 14 elongations, it can only drive the inverted "L" shaped lever and upward deflect, and these stock 8 downforce are reduced, and these switch 2 resilient contacts 3 are complied with himself elastic recoil, and open dehumidifier, make dehumidifier start work.This film 14 just can be controlled the outage or the energising of sensitive switch automatically with air humidity varies like this, reaches the purpose of automatic controlled humidity.It is to be used for setting the pairing air humidity of this switch motion that preset screw 9 of this switch designs and adjusting knob 18 and humidity thereof are set cam 15.So just can adapt to different user to humidity requirement, realize that the small-sized household dehumidifier has the high effect of degree of regulation.
