Description

Electronic cigarette air film switch

Technical field

The utility model belongs to a kind of mechanical switch, especially refers to the air film switch that uses in a kind of electronic cigarette.

Background technology

Electronic cigarette often utilizes the starter of air film switch as atomization circuit, when the user makes aspiratory action at the suction nozzle place of electronic cigarette, and air film switch stress deformation connection circuit.

Disclose a kind of like this mechanical type air film switch in the prior art, it comprises switch membrane, is used under the both sides of film have the situation of pressure differential deformation taking place; Be connected in the switch base in the switch membrane outside, form first chamber in order to a side at switch membrane; Also comprise being fixed in and be positioned at the switch membrane opposite side, be fixed in the connecting ring of switch base, form second chamber in order to opposite side at switch membrane, on described switch base, also be fixed with first electrode slice and second electrode slice that electricity separates, on switch membrane, one side of described first chamber is fixed with cylindrical fixed leg, in switch base, has the hole that allows fixed leg to move vertically, the other end of the fixed leg cylindrical conductive bar that is connected, described fixed leg and conducting rod can be when first chamber and second chamber produce pressure differential, move to the primary importance that is communicated with first electrode slice and second electrode slice and away from the second place of first electrode slice and second electrode slice with switch membrane.

Yet the weak point of this air film switch is, because the quality of cylindrical conductive bar is excessive, causes the sensitivity of switch not high, in addition, when assembling, is difficult to guarantee that the cylindrical conductive bar accurately cooperates with fixed leg.

The utility model content

A purpose of the present utility model is to solve weak point of the prior art, provides a kind of quality to be easy to more for a short time to assemble and electronic cigarette air film switch that sensitivity is higher.

For achieving the above object, electronic cigarette air film switch provided by the utility model comprises

Switch membrane has the flexible glue film that deformation can take place because of the pressure at both sides difference;

Switch base is fixed on a side of switch membrane, forms first chamber, and has an axially extending bore in the middle;

Connecting ring is fixed in the opposite side of switch membrane, forms second chamber;

Fixed leg passes the axially extending bore of described switch base, is fixed on described switch membrane;

First electrode and second electrode, electricity separates is fixed on described switch base; And,

Conducting strip is fixed on described fixed leg; According to the utility model, described conducting strip is elongated, have with corresponding first contact jaw of first electrode and with corresponding second contact jaw of second electrode, have the hole of matching in order to fixed leg at the middle part of described conducting strip.

Further, first contact jaw of described conducting strip and second contact jaw are prong shape.

The beneficial effects of the utility model are, are provided with circular hole in the middle of the described conducting strip, be easy to and fixed leg between accurate location and assembling.Two ends are designed to prong shape, have improved the sensitivity of conducting and disconnection on largely.

Embodiment

The utility model relates to a kind of air film switch that is used for electronic cigarette, and this air film switch is easy to assembly, and clever density height, below in conjunction with accompanying drawing, the utility model is elaborated.

Fig. 1 is the STRUCTURE DECOMPOSITION figure according to the air film switch of a kind of embodiment of the present utility model, and Fig. 2 is the structural front view of the air film switch after making up.With reference to Fig. 1, electronic cigarette air film switch comprises switch membrane 1, switch base 2, connecting ring 3, fixed leg 4, the first electrodes, 5, the second electrodes 6 and conducting strip 7.

Wherein, switch membrane 1 has the flexible glue film 11 that deformation can take place because of the pressure at both sides difference; Switch base 2 is fixed on a side of switch membrane 1, forms first chamber 21, has an axially extending bore 22 at the middle part of switch base 2; Switch base 2 can with the switch membrane clamping; Connecting ring 3 is fixed in the opposite side of switch membrane, as by adhesive, forms second chamber 31; Fixed leg 4 passes the axially extending bore 22 of described switch base 2, as by adhesive etc., is fixed on flexible glue film 11 middle parts of described switch membrane 1; Like this, the diriven motion of flexible glue film 11 can cause fixed leg 4 to move along through hole 22 with it; First electrode 5 is formed by fixed part 51 with by the outward extending contact site 52 of fixed part, second electrode 6 is formed by fixed part 61 with by the outward extending contact site 62 of fixed part, the fixed part 51 that utilizes first electrode is with first electrode, by as modes such as binding agents, be fixed on switch base, the fixed part 61 that utilizes second electrode is with second electrode, by as modes such as binding agents, be fixed in switch base, after fixing, keep first electrode to power at switch base and separate with second electrode.The contact site 52 of first electrode is respectively applied for the control circuit that is connected electronic cigarette with the contact site 62 of second electrode

Conducting strip 7 is elongated, have with corresponding first contact jaw 71 of first electrode and with corresponding second contact jaw 72 of second electrode, have the hole 73 of matching in order to fixed leg 7 at the middle part of described conducting strip.By this hole, conducting strip 7 can be assemblied in fixed leg 6 easily, conducting strip 7 and fixed leg 6 can be bonding by adhesive.

When described first chamber and second chamber did not have pressure differential, promptly when the suction nozzle place of electronic cigarette did not have aspiratory action, the flexible glue film 11 of switch membrane 1 can not move, conducting strip under the support of fixed leg away from the fixed part of first electrode and second electrode; In second chamber, produce negative pressure, promptly when the suction nozzle place of electronic cigarette does not have aspiratory action, flexible glue film 11 drives fixed leg and moves along through hole 22, thereby drive the fixed part motion of conducting strip 7 to first electrode and second electrode, and finally its first contact jaw, second contact jaw contact conducting first electrode and second electrode with the fixed part of first electrode and second electrode respectively.

Shown in Fig. 2 C, 3, first contact jaw 71 of conducting strip 7 and second contact jaw 72 can be prong shape, like this, can make its with the contact of the fixed part of first electrode, second electrode with separate sensitive more.
