Description
Technical field
This utility model relates to a kind of field of switches, and especially a kind of electron wind compresses switch.
Background technology
Blast switch is a kind of detecting element, is commonly used in and needs blast mechanically, such as pneumatic press, pneumatic clipper
Trigger, gas heater, gas fired-boiler, gas furnace, wall-hung boiler etc. use the electric equipment products of combustion gas classes, and it is utilize gas quiet
Pressure promotes microswitch to realize the break-make of electric current.
Traditional blast switch generally includes housing, is arranged at air inlet and the gas outlet of housing outer surface, is arranged at
Control assembly in housing, its operation principle is that blast switch is off under normal circumstances, when blower fan normally works, blast
The pressure difference that switch diaphragm both sides produce is 0, and its output voltage, so that main circuit is connected smoothly, it is ensured that machine normal
Run.On the contrary, when blower fan irregular working, blast switch barrier film both sides will produce pressure reduction, circuit board systems output height
Level makes main circuit carry out break-make so the effect of being effectively controlled.But there are the following problems for existing blast switch, such as Shen
Please number be the blast switch of a kind of wall-hung boiler mentioned in 201420539406.2, conductive pole be provided with projection, utilizes this convex
Block pressing turns on metal clips, but in use, metal clips is owing to only applying on an axial direction
Pressing bed knife, easily offsets during some use, causes using effect the best.
Summary of the invention
Problem to be solved in the utility model is: the electron wind providing a kind of in use structure more stable compresses switch.
For solving above-mentioned technical problem, including upper shell and fix the lower house being connected with upper shell, described upper shell
Outer surface is respectively arranged with air inlet and venthole, is provided with the circuit controling assembly of control circuit break-make in described lower house,
Described circuit controling assembly includes the conductive seat being arranged at lower house inner surface, is arranged on conductive seat for logical with on conductive seat
Disconnected flat thin magnet, and be arranged at the flat thin magnet upper axial end fixing seat for fixed magnet sheet, on described fixing seat and Magnet
The sheet place of leaning is provided with the pressing projection that can press flat thin magnet, and it is horizontal that described conductive seat is provided with flat thin magnet cross spacing
Locating part.
After have employed technique scheme, after being provided with prototype cross spacing part so that make Magnet during voltage turn-on
When sheet produces displacement, air pressure generation pressure reduction changes pressure change simultaneously.So obtaining while being closed by cross spacing part
Fixing effect, in use, structure also can more be stablized, on the other hand, also enhance whole blast switch
Service life.
As further improvement of the utility model, described cross spacing part is for being arranged at conductive seat upper surface left and right two
The projection of side, the distance between said two projection is equal with the width of flat thin magnet.
After have employed said structure, owing to cross spacing part is arranged at the projection of conductive seat upper surface arranged on left and right sides, use
Protruding structure reaches the technique effect of cross spacing, and the distance between two projections is equal with the width of flat thin magnet,
Then further increase spacing fastening degree.
Accompanying drawing explanation
Fig. 1 show blast switch exploded perspective view.
Detailed description of the invention
As it is shown in figure 1, include upper shell 1 and the lower house 2 that be connected fixing with upper shell 1, described upper shell 1 outer surface
It is respectively arranged with air inlet and venthole, in described lower house 2, is provided with the circuit controling assembly of control circuit break-make, described electricity
Road controls assembly and includes the conductive seat 3 that is arranged at lower house 2 inner surface, be arranged on conductive seat 3 for break-make on conductive seat
Flat thin magnet 4, and be arranged at the flat thin magnet 4 upper axial end fixing seat 5 for fixed magnet sheet 4, with magnetic on described fixing seat 5
Iron plate 4 place of leaning is provided with the pressing projection 51 that can press flat thin magnet 4, and described conductive seat 3 is provided with and is laterally limited by flat thin magnet 4
The cross spacing part 6 of position.After being provided with pressing projection 51 and cross spacing part 6 so that flat thin magnet 4 is horizontal and vertical
Upwards being obtained for fixation, in use, structure also can more be stablized, and on the other hand, also enhances whole wind
The service life compressed switch.Described cross spacing part 6 is the projection 61 being arranged at conductive seat upper surface arranged on left and right sides, described two
Distance between individual projection is equal with the width of flat thin magnet.Owing to cross spacing part is arranged at conductive seat upper surface arranged on left and right sides
Projection, use protruding structure to reach the technique effect of cross spacing, and the distance between two projections and flat thin magnet
Width equal, then further increase spacing fastening degree.
Claims (2)
1. a blast switch, including upper shell and fix the lower house being connected with upper shell, described upper shell outer surface divides
It is not provided with air inlet and venthole, in described lower house, is provided with the circuit controling assembly of control circuit break-make, described circuit
