Description

Safety-type gas kitchen ranges timer

(1). technical field: the utility model relates to the transformation of kitchen range safety device, is a kind of safety-type gas kitchen ranges timer.

(2). background technology: the timer in the existing gas kitchen ranges flame-out protection device generally is to adopt the universal timer of household electrical appliances, and control circuit contact in this type timer or employing are open types or adopt closed type; This type timer is used for the problem that gas kitchen ranges exists: flame-out protection device in the kitchen range and the igniter in the kitchen range are to carry out interlocking with the control circuit of timer; Igniter conducting in case timer starts in the kitchen range; And the blowout protection circuit in the kitchen range must break off, and causes kitchen range to light by very fast quilt, must the repeatable operation timer regularly, return just can light kitchen range; The kitchen range ignition operation is inconvenient, and the potential safety hazard of kitchen range is big.

(3). summary of the invention: the purpose of the utility model is exactly to solve existing ignition operation inconvenience of existing kitchen range timer and the big problem of kitchen range potential safety hazard, and a kind of safety-type gas kitchen ranges timer is provided.

The concrete scheme of the utility model is: a kind of safety-type gas kitchen ranges timer, and it has shell, and timer is installed in the shell, and timer is provided with ratchet; It is characterized in that: trigger mechanism is installed above timer; Described trigger mechanism is made up of percussion hammer and stage clip; Stage clip is mounted in the top of percussion hammer, and percussion hammer is mounted in the top of timer and keeps in touch with ratchet in the timer, and percussion hammer is provided with tup; On the shell wall in shell left side, be separately installed with static contact and elasticity moving contact; Static contact and moving contact are respectively equipped with the contact; The right-hand member of moving contact also is provided with and hits a little; Keep in touch two contacts of described static contact and moving contact, and the tup in the described percussion hammer is to contact with hitting a little of moving contact at extreme position.

The described percussion hammer of the utility model is provided with elastic rocking beam, and tup is provided in a side of the left end of elastic rocking beam, and the right-hand member of elastic rocking beam is provided with installing hole, and the below of elastic rocking beam is provided with push rod; Described percussion hammer is to adopt bearing pin to constitute with shell to install at the installing hole place, the push rod in the percussion hammer be with timer in the ratchet outline keep in touch, the stage clip that the percussion hammer top is installed is the push rod installation that faces on the elastic rocking beam.

The operation principle of the utility model (seeing Fig. 1 for details): static contact 4 in the utility model and moving contact 5 be with kitchen range in blowout protection circuit polyphone connect (reflection among the figure); Open the then blowout protection circuit turn-on in the kitchen range of the utility model; The also conducting of the gas circuit of kitchen range; When the tup in the utility model trigger mechanism percussion hammer 2 10 bump moving contacts 5 hit a little 7 the time, static contact 4 breaks off with two contacts 6 of moving contact 5, the blowout protection circuit disconnection in the kitchen range; The gas circuit of gas kitchen ranges also is cut off, and the gas circuit that must restart timer 8 kitchen range could conducting.

Two contacts of trigger mechanism triggering dynamic/static contact, 6 disconnections in the timer 8 and the operation principle that resets are: start timer 8; Push rod 12 in the trigger mechanism percussion hammer 2 be with timer 8 ratchets 9 in excircle configuration keep in touch; When timer 8 operations arrive timing; Excircle configuration from ratchet 9 drops in the notch of ratchet 9 push rod 12 in the percussion hammer 2 in effect following moment of stage clip pressure; What the tup 10 of percussion hammer 2 elastic rocking beams 11 left ends clashed into moving contact 5 under the effect of whereabouts inertia force hits a little 7, and the contact 6 of moving contact 5 is broken off with the contact of static contact 46, and circuit then breaks off; After the kinetic energy of percussion hammer 2 tups 10 disappears, tup 10 return and break away from and hit a little 7 contact under the effect of elastic rocking beam 11 elastic force with moving contact 5, the contact 6 of moving contact 5 resets and keeps in touch with the contact 6 of static contact 4, and circuit is conducting again.

The utility model is compared with existing kitchen range timer; Two contacts of moving contact in the utility model and static contact are to be designed to normally off; And newly established break-make electricity trigger mechanism; Moving contact and static contact be with kitchen range in flame-out protection device polyphone connect, the igniter in the kitchen range is to be opened by another igniting to send control, has realized the flame-out protection device timing controlled in the kitchen range; Close the generation that fire can not cause the bad accident of dry combustion method etc. yet even kitchen range have been forgotten, the igniting effect of kitchen range is also improved rapidly; The utlity model has kitchen range blowout protection timing controlled and auto-reset function, the utility model kitchen range ignition operation is more convenient; The utility model is simple in structure, dependable performance, be widely used and cost at the bottom of honest and clean; The utility model preferably resolves existing ignition operation inconvenience of existing kitchen range timer and the big problem of kitchen range potential safety hazard.
