Description

Pneumatic switch

Technical field

A kind of microswitch, more particularly to a kind of pneumatic switch are the utility model is related to, belongs to internet of things field.

Background technology

In recent years, in the market has emerged in large numbers various central fresh air system and air purifier, wherein having quiet using IFD Electric precipitation, and IFD electrostatic precipitations need blower fan work, drive air flow；Needed when air flow to IFD charging fields electric From so that the dust of air, foreign matter etc. become electrically charged particle, then with the distinguished and admirable high voltage electric field by IFD, pass through powerful electricity Field achievees the purpose that purification.

When blower fan work, the other equipments such as purification can be automatically controlled.And its implementation can be by sensing wind turbine Operating current operate, but there are it is huge the drawbacks of, for example load is perceptual, resistive or capacitive, and load voltage should use Exchange or direct current are a problems, and power supply characteristic of wind turbine etc. can all influence this inductive effects.

It would therefore be highly desirable to solve the above problems.

Utility model content

Purpose of utility model：The purpose of this utility model is to provide that a kind of mechanical action is simple and reliable, low processing cost And the pneumatic switch of small wind pressure can be sensed.

Technical solution：The utility model discloses a kind of pneumatic switch, including the blade that keeps out the wind that can be rotated around air port upper end With the inductive switch for induction air pressure being arranged on above air port, which is equipped with sensing chip and sense contact；Wind The blade that keeps out the wind for blowing air port is rotated to horizontal direction, and the blade that keeps out the wind in rotation process suppresses sensing chip active force in sense contact On, touch inducing inductive switching wind pressure.The pneumatic switch suppresses sensing chip triggering inductive switch to realize reality by the blade that keeps out the wind When wind pressure sensing, using the simple and reliable of mechanical action, realize wind pressure control.

Wherein, the blade that keeps out the wind has the cambered surface wind gathering spoon for being used for reducing windage upwards windward.The design of the wind gathering spoon It is ingenious to add wind gathering effect, it can be achieved that the sensing of small wind pressure.

Preferably, the blade that keeps out the wind is leeward is equipped with reinforcing rib upwards.Further, the front end of the sensing chip is equipped with rolling Wheel, the blade that keeps out the wind that wind blows air port are rotated to horizontal direction, and the surface of roller contact reinforcing rib, is suppressed at the same time in rotation process Sensing chip active force is in sense contact, touch inducing inductive switching wind pressure.The reinforcing rib can be effectively increased the strong of the blade that keeps out the wind Degree, in addition with roller contact process, for break-in roller, avoiding during use roller from galling the blade that keeps out the wind influences wind gathering effect Fruit, effectively extends the service life of pneumatic switch.

Preferably, the blade that keeps out the wind passes through axis and the movable connection in air port upper end of keeping out the wind.

Furthermore the axis that keeps out the wind is equipped with inductive switch stent.

Preferably, there is NC interfaces, NO interfaces and COM foot interfaces on the inductive switch.

Beneficial effect：Compared with prior art, its advantage is the utility model：The pneumatic switch passes through the blade that keeps out the wind first Compacting sensing chip triggers inductive switch to realize real-time wind pressure sensing, using the simple and reliable of mechanical action, realizes wind pressure control System；Secondly the ingenious in design of wind gathering spoon adds wind gathering effect, it can be achieved that the sensing of small wind pressure in the utility model；Furthermore this Reinforcing rib can be effectively increased the intensity for the blade that keeps out the wind in utility model, in addition with roller contact process, for break-in roller, keeping away Roller worn-off keeps out the wind blade so as to influence wind gathering effect during exempting from use, effectively extends the service life of pneumatic switch；Finally The pneumatic switch mechanical action is simple and reliable, structure low processing cost, and service life is high, easy to marketing.

Brief description of the drawings

Embodiment

The technical solution of the utility model is described further below in conjunction with the accompanying drawings.

As depicted in figs. 1 and 2, a kind of pneumatic switch of the utility model, including keep out the wind blade 1 and inductive switch 2.Keep out the wind leaf Piece 1 is by axis 8 and the movable connection in air port upper end of keeping out the wind, and under the blowing of wind, the blade 1 that keeps out the wind can be by the i.e. vertical dress of nature Put and turn to horizontality.The blade 1 that keeps out the wind has the cambered surface wind gathering spoon 5 for being used for reducing windage upwards windward, while is keeping off The leeward of air blade 1 is equipped with reinforcing rib 6 upwards.The ingenious in design of the wind gathering spoon adds wind gathering effect, it can be achieved that small wind pressure Sensing.

The above-mentioned axis 8 that keeps out the wind is equipped with inductive switch stent 9.Inductive switch 2 is installed on the inductive switch stent 9, the sense Inductive switch 2 is equipped with sensing chip 3 and sense contact 4, and the front end of sensing chip 3 is equipped with roller 7, and wind blows the blade 1 that keeps out the wind in air port Rotated to horizontal direction, roller 7 contacts the surface of reinforcing rib 6 in rotation process, while suppresses 3 active force of sensing chip and touched in sensing On point 4, touch inducing switchs 2 induction air pressures.Reinforcing rib can be effectively increased the intensity for the blade that keeps out the wind in the utility model, in addition with In roller contact process, for break-in roller, avoid during use roller from galling and keep out the wind blade so as to influence wind gathering effect, have Effect extends the service life of pneumatic switch.

There is NC interfaces, NO interfaces and COM foot interfaces on above-mentioned inductive switch 2.

The pneumatic switch of the utility model suppresses sensing chip triggering inductive switch to realize real-time wind pressure by the blade that keeps out the wind Sensing, using the simple and reliable of mechanical action, realizes wind pressure control；The pneumatic switch mechanical action is simple and reliable, structure processing Of low cost, service life is high, easy to marketing.
