Description
Technical field
This utility model belongs to the technical field of car load gas handling system design, more particularly to a kind of hysteresis control formula blocking report
Alert device.
Background technology
The shortcoming that traditional air filter obstruction alarm device is present：During air filter is gradually clogged, formed
Negative pressure when reaching in a basic balance with spring force, due to automobile jolting in the process of moving, the alarm device dynamic and static
Disconnected phenomenon when touching when occurring irregular between contact, causes display lamp or buzzer irregular, discontinuity scintillation occur.With
Upper phenomenon causes prompting that sometimes can not be promptly and accurately to drive attendant's cleaning replacement filter element.Meanwhile, display lamp or buzzer
Long-time flicker also results in each element in circuit includes that the performance of alarm device itself reduces and reduced lifetime.
Content of the invention
In order to solve the problem above of prior art presence, this utility model provides a kind of hysteresis control formula blocking and reports to the police
Device, using the principle of opposite sex attraction of permanent magnetism, realizes the delayed alarm function of air filter blocking warner, and can be with trace regulation
Alarming value and delay value scope.
Content of the present utility model is realized by below scheme：
A kind of hysteresis control formula blocking warner is provided, including a permanent magnetism, No. two permanent magnetism, static contact, No. two quiet
Contact, movable contact spring, spring, piston, shell, adjusting nut, vacuum chamber, power supply, indicator；Enclosure is provided with vacuum chamber, and one
Number permanent magnetism and No. two permanent magnetism are arranged on the placement of vacuum chamber inscribe opposite polarity, and a permanent magnetism is fixed outside by adjusting nut
On shell, No. two permanent magnetism are fixed on piston outer end, and the piston other end is fixed with movable contact spring, and spring is socketed on piston and abuts outside
Between shell and movable contact spring, a static contact and No. two static contacts are arranged on shell, and static contact, No. two static contacts,
Indicator is connected with power circuit.
Compared with traditional blocking warner, the hysteresis control formula blocking warner that this utility model is provided, using permanent magnetism
Principle of opposite sex attraction, realizes the delayed alarm function of air filter blocking warner, and can be with trace regulation alarming value and time delay
Value scope, so that overcome conventional alarm equipment alarm pressure transient defect.

Specific embodiment
Of the present utility model specific embodiment is described in detail below in conjunction with the accompanying drawings.
This utility model provides a kind of hysteresis and controls formula blocking warner, can be used as the air filter used by automobile
Clogging automatic alarm device, including a permanent magnetism 1, two permanent magnetism 2, one static contact 3, No. two static contacts 4, movable contact springs 5, bullet
Spring 6, piston 7, shell 8, adjusting nut 9, vacuum chamber 10, power supply 11, indicator (display lamp or buzzer) 12.
Vacuum chamber 10 is provided with inside shell 8, and a permanent magnetism 1 and No. two permanent magnetism 2 are arranged on 10 inscribe polarity of vacuum chamber
Contrary placement, a permanent magnetism 1 are fixed on shell 8 by adjusting nut 9, can adjust a permanent magnetism 1 and two by adjusting nut 9
The spacing of number permanent magnetism 2, No. two permanent magnetism 2 are fixed on 7 outer end of piston, and 7 other end of piston is fixed with movable contact spring 5, and spring 6 is socketed in work
On plug 7 and be connected between shell 8 and movable contact spring 5, a static contact 3 and No. two static contacts 4 be arranged on shell 8 and with dynamic
5 position of contact is relative, and 3, No. two static contacts 4 of a static contact, indicator 12 are connected with 11 circuit of power supply.
Compared with traditional alarm, of the present utility model theing improvement is that is provided with a pair of permanent magnetism in vacuum chamber 10
Body, the permanent magnetism 1 being respectively fixed on shell 8 by adjusting nut 9 and No. two permanent magnetism 2 being fixed on piston 7, both
Opposite polarity is placed, using the principle of opposite sex attraction of permanent magnetism.When there is air filter blocking, negative pressure increase in vacuum chamber 10, negative
Acting force of the spring is overcome under the captivation collective effect of pressure active force and a permanent magnetism 1 and No. two permanent magnetism 2, and then is driven
Piston 7 and movable contact spring 5 overcome the active force of spring 6, a number static contact 3 of conducting and No. two static contacts 4.So as to connect whole report
Alert circuit.When there is blocking, as long as dynamic and static contact is once contacted, circuit turn-on.Now, according to permanent magnetism interaction force with
Spacing variation characteristic understands, due to a permanent magnetism and the infinite approach of No. two permanent magnetism, circuit communication state by permanent magnetism locking, when sending out
During raw negative pressure minor fluctuations, as magneticaction will not also come in contact bounce situation.Display lamp or buzzer are i.e. by normality point
Bright and warning, points out driving attendant clean or change the filter element of air filter.When negative pressure persistently reduces, spring 6 is made
More than after magnetic force maximum, then a permanent magnetism and No. two permanent magnetism are separated active force, due to the active force between permanent magnetism and distance
Curve linear relationship characteristic for saltant type steep curve, so, the permanent magnetic action power after separating is strongly reduced, and piston 7 is rapid to return
Position.Then circuit loop is disconnected, and alarm device automatically resets.
Adjusting nut 9 can finely tune distance between permanent magnetism according to pressure demand, so as to ensure to overcome negative pressure floating difference
Scope, can be with trace regulation alarming value and the scope from drop lock.
