Abstract
The invention discloses a pneumatic switching component for a heater. The pneumatic switching component comprises a microswitch, an electromagnetic valve and a control circuit board, wherein, the electromagnetic valve is arranged on a gas conveying pipeline; a spring lamination of the microswitch is connected with a stress thin slice which is arranged oppositely to a draught fan blade; two electrodes of the microswitch are connected with the electromagnetic valve by the control circuit board. When the draught fan is started, the blade rotates to generate wind, and the wind blows the stress thin slice to apply constant thrust force; therefore, a moving contact and a static contact on the tail end of the spring lamination of the microswitch can be communicated; the control circuit board controls the electromagnetic valve to start, so that the gas conveying pipeline is kept smooth to cause the heater generate to heat; when the draught fan is closed or has exceptions, the thrust force of the wind disappears or is weakened under the condition of calm air or weak wind, the spring lamination generates opposite acting force, the moving contact is separated from the static contact, the control circuit board controls the electromagnetic valve to cut off the gas conveying pipeline, thereby ensuring safe use of the heater. Furthermore, the using operation of the component is more convenient and more reliable.
Description
Technical field
The present invention relates to a kind of warmer, particularly relate to a kind of Pneumatic switch components of warmer.
Background technology
At present, the range of application of industrial warming apparatus more and more widely, such as the drying that can be used for the construction site, the preheating of equipment, the heating etc. of heating of various job shops; This class warmer mainly comprises blower fan, and head is burnt in the combustion chamber, is used for the fuel cartridge of storage of fuels.Fuel cartridge is injected the burning head that drainage tube is delivered in the combustion chamber again with fuel by gas pipeline and is burnt, and fan blade rotates and produces wind, passes burning the heat that the head burning produces in the combustion chamber.
But above-mentioned warmer is not taked safety precautions; as run into blower fan and break down; when blade can not rotate; burning head is also burning away; the one, cause energy waste, the 2nd, cause the heat of combustion chamber in time to pass, if can not in time find; certainly will cause very serious consequence, directly have influence on the safety of user and surrounding environment.Moreover, as when closing after using, need close fuel cartridge earlier, and close blower fan then, very inconvenient; Sometimes close one of them because carelessness is forgotten, still can cause bad consequence.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of Pneumatic switch components of warmer is provided, it can control the break-make of fuel gas transportation pipeline according to the working order of blower fan, thereby has played protective effect, has improved the safety in utilization of warmer.
Technical scheme of the present invention is achieved in that
A kind of Pneumatic switch components of warmer, comprise microswitch, magnetic valve and control circuit board, magnetic valve is arranged on the fuel gas transportation pipeline, and the spring leaf of microswitch is connected with the stressed thin slice that is provided with over against fan blade, and two electrodes of microswitch connect magnetic valve by control circuit board.
As preferably, the thickness of described stressed thin slice is 0.2mm～1.5mm.
As preferably, described stressed thin slice is a regular shape or irregularly shaped.
As preferably, described stressed thin slice be shaped as any shape in circle, ellipse or the rectangle.
As preferably, this assembly also includes compartment, and microswitch is fixed in the compartment, and spring leaf stretches out from the lower ending opening of compartment.
As preferably, the equal opening of the lower end of described compartment and right-hand member, microswitch is by being bolted in the compartment, and the upper end of compartment is connected with fixed head.
Adopted the principle of the present invention and the beneficial effect of technique scheme to be: when blower fan is opened, blade rotation produces wind, the moving stressed thin slice of wind applies a constant thrust, thereby make the movable contact and the stationary contact of the spring leaf end of microswitch keep connecting, control circuit board control magnetic valve starts, and makes fuel gas transportation pipeline keep unimpeded so that warmer produces heat; When blower fan cuts out or takes place unusual, under the calm or weak wind condition, the thrust of wind disappears or weakens, spring leaf produces opposition, movable contact and stationary contact disconnect, the effect of control circuit board control magnetic valve disconnects fuel gas transportation pipeline, thereby has guaranteed the safe in utilization of warmer, also uses operation more convenient reliable in addition.

Fig. 2 is the view of blower fan pneumatic switch when running well;
Fig. 3 is the explosive view of microswitch and compartment;
Fig. 4 is the installation diagram of microswitch and compartment.
The specific embodiment
The specific embodiment of the present invention is as follows:
Embodiment: a kind of Pneumatic switch components of warmer, as shown in Figure 1 and Figure 2, comprise microswitch 2, magnetic valve 4 and control circuit board 3, magnetic valve 4 magnetic valves are arranged on the warmer fuel gas transportation pipeline, the end of the spring leaf 5 of microswitch 2 is connected with the stressed thin slice 6 that is provided with over against fan blade, and stressed thin slice 6 is a steel disc or iron plate, and it is shaped as regular circular, for alleviating own wt, its thickness is 0.3mm; Two electrodes of microswitch 2 connect magnetic valve 4 by control circuit board 3.
As shown in fig. 1, when blower fan 1 is not opened or be in improper running, promptly when calm or weak wind state, the spring leaf 5 of microswitch 2 produces opposition, movable contact and stationary contact disconnect, 4 effects of control circuit board 3 control magnetic valves disconnect fuel gas transportation pipeline, thereby have guaranteed the safe in utilization of warmer.As shown in Figure 2, when blower fan 1 is opened or is in normal operation, wind-force is normal, the direction of arrow indication is a wind direction, wind has applied a constant thrust to stressed thin slice 6, thereby pressuring spring sheet 5 makes the movable contact of spring leaf 5 ends and stationary contact keep connecting, control circuit board 3 output signals control magnetic valve 4 starts, and makes fuel gas transportation pipeline keep unimpeded so that warmer produces heat.
As shown in Figure 3, for preventing that the microswitch immersion from damaging, this assembly also includes compartment 7, the equal opening of the lower end of described compartment 7 and right-hand member, microswitch 2 is fixed in the compartment 7 by bolt 8, and spring leaf 5 stretches out from the lower ending opening of compartment 7, and the right side, upper end of compartment 7 is connected with fixed head 9, be provided with the screw installing hole on fixed head 9, compartment 7 can be fixed on the warmer by fixed head 9.
