Description
Technical field
The present invention relates to a kind of switch of the change operation by physical state, particularly a kind of mechanical type dumping switch.
Background technology
For gas appliance movably, as place unreasonablely, when under the situation of inclination certain angle, using, will influence the normal running conditions of burner, cause combustion instability, increase the abnormal operating states such as carbon monoxide content in the burnt gas, serious meeting produces security incident.For preventing the generation of the bad phenomenon that this class inclination combustion gas tool causes, on some combustion gas tools, anti-dumping switch is housed, after burner tilted to certain angle, the control gas lockout valve carried out safeguard protection to burner.This type of switch adopts mercoid switch mostly at present, and this type of switch costs an arm and a leg, is absolutely unsafe, and mercury easily causes environmental pollution and make the operator that mercurial poisoning take place easily that existing in the world a large amount of countries ban use of.Chinese patent application number 87200534 disclosed object displacements are reported to the police and are used position-sensing switch, use mercury bead to produce alarm signal as electric conductor, just have above-mentioned weak point.Chinese patent application number 98117787.5 disclosed inclinations pass the prestige device in addition, Chinese patent application number 01142166.5 disclosed 360 deg does not have the installation direction restriction and can all belong to the mechanical type control switch by automatically reset induction installation, they all are installed on a plurality of contacts in equipment, still contact during for device inclined and conduct electricity or send the signal of telecommunication with other contact, they exist structure complicated, processing and manufacturing is difficult for, cost height, structure all are not suitable for the security control to gas kitchen ranges.
Summary of the invention
Realize the dumping switch of mechanical type control when the purpose of this invention is to provide a kind of equipment and toppling over by mechanical heavy ball change in location.
The present invention realizes with following mode: the mechanical type dumping switch has epicoele, conical cavity and the cavity of resorption of connection in its housing, the bottom of the epicoele of housing and the connected chamber of cavity of resorption are conical cavity, sensitive switch is housed in the cavity of resorption, the shell wall that the electric lug plate of sensitive switch passes housing stretches out outside housing, the switch feeler lever position of sensitive switch is over against conical cavity, heavy ball is contained in the epicoele, the accent upper end of the epicoele of loam cake cap seal housing.The bottom of heavy ball is pressed in the switch feeler lever place of sensitive switch, and it is depressed, and heavy ball is supported in the housing place of the conical cavity of epicoele bottom, and the sensitive switch electricity is connected.The mechanical type dumping switch is toppled over, and heavy ball breaks away from the switch feeler lever of sensitive switch, and is supported on the housing of epicoele, and the switch feeler lever ejects and resets, and the sensitive switch electricity disconnects.The diameter dimension of heavy ball is greater than the diameter dimension of conical cavity.Heavy ball is steel ball or shot.
This mechanical type dumping switch is simple in structure, and working stability is reliable, and either direction tilts in 360 degree scopes, can both play the safeguard protection effect of shut-off circuit.It can be used for cutting off gas supply when movably the combustion gas tool is because of the unreasonable run-off the straight in position, plays combustion gas tool accident extinguishing safeguard protection effect.Also can be used for preventing the inclination safeguard protection on the product that other appliances prevent from work.

Embodiment
Below in conjunction with accompanying drawing this mechanical type dumping switch is described in further detail:
The heavy ball 1 main effect of this mechanical type dumping switch is a switch feeler lever 3 of pushing down sensitive switch 2 at burning appliance when vertical, and it is compressed into sensitive switch 2, sensitive switch 2 is in electric on-state, when burning appliance departs from the vertical position inclination, heavy ball 1 can be scalene cones because of the chamber wall of conical cavity 9, and heavy ball 1 is rolled and moved the center, disengages with switch feeler lever 3, switch feeler lever 3 ejects and resets, and sensitive switch 2 is in electric closed condition.Steel ball is used in heavy ball 1.
This mechanical type dumping switch is equipped with heavy ball 1 and sensitive switch 2 in housing 4.Housing 4 internal cavities are divided into epicoele 7, conical cavity 9 and cavity of resorption 8.Conical cavity 9 is to connect epicoele 7 and cavity of resorption 8 transition connection chambers.Sensitive switch 2 is housed in cavity of resorption 8, and two electric lug plates 6 of sensitive switch 2 pass housing wall and extend, and the switch feeler lever 3 of sensitive switch 2 is over against conical cavity 9.Heavy ball 1 is contained in the epicoele 7, and when the mechanical type dumping switch was vertical, heavy ball 1 tumbled in the chamber of conical cavity 9, and the switch feeler lever 3 of sensitive switch 2 is pushed down in heavy ball 1 lower end, and this feeler lever is compressed into sensitive switch 2, and sensitive switch is in on-state.The upper end accent of the epicoele 7 of loam cake 5 cap seal housings 4.Accompanying drawing 1 is the structural representation of mechanical type dumping switch when being in vertical state, and this moment, sensitive switch 2 was in electric on-state.Fig. 3 is in heeling condition for the mechanical type dumping switch, heavy ball 1 displacement, and switch feeler lever 3 ejects automatically and resets, and sensitive switch 2 is in electric closed condition.Sensitive switch 2 is the repackings of selection standard product, and the sensitive switch moment of selecting for use is little, conducting resistance is little.
During operating position, two electric lug plate 6 series electrical of mechanical type dumping switch are connected on the thermocouple circuit of electrothermal combustion gas tool protector of accident extinguishing.When burner (promptly at vertical position) in normal working conditions; steel ball 1 (being heavy ball) in the mechanical type dumping switch is pressed on the switch feeler lever 3 (claiming the contact again) of sensitive switch 2; and feeler lever depressed; make sensitive switch 2 be in electric on-state; make the protector of accident extinguishing circuit on the combustion gas tool also be in normal operating conditions, make the burner operate as normal.
When burner tilts to certain angle; steel ball 1 (being heavy ball) in the mechanical type dumping switch moves with the incline direction of combustion gas tool; leave the switch feeler lever 3 (claiming the contact again) of sensitive switch 2; feeler lever ejects and resets, and makes sensitive switch 2 be in off-state, makes the protector of accident extinguishing circuit on the combustion gas tool be in open-circuit condition; the outage of burner safeguard protection electromagnetically operated valve; electromagnetically operated valve discharges closes gas valve, cuts off gas supply, plays the safeguard protection effect.Under combustion gas tool recovery normal running conditions, the steel ball 1 in the mechanical type dumping switch automatically resets, and feeler lever is depressed, and sensitive switch 2 is connected, and the protector of accident extinguishing circuit of combustion gas tool is in normal operating conditions, and burner can normally use.
The combustion gas tool that this mechanical type dumping switch is used in vertical state work is made the switch of protective device and is used.Can be widely used in the protection switch of the protector of accident extinguishing of vertical outdoor heater and indoor heater, coal gas light fixture.
