Abstract
The utility model discloses a piezoelectric ceramic automatic igniter for gas stove. The upper part of a switch button spindle is in the shape of flat square steps on which a pusher dog and a spring are arranged; the middle part of the steps is provided with a pawl pusher block. The switch button spindle drives the pusher dog to rotate through a switch plate hole. The piezoelectric ceramic matched with a claw type slide block can contact the pusher dog. A telescopic rod and a spring are arranged in a telescopic box; one end of the telescopic rod is provided with a spray point; the other end can contact the pawl pusher block. When igniting, the spray point approaches the burner and ignites immediately and automatically, and moves away from the heat source after igniting. The utility model has the advantages of long service life, high reliability, simple structure and low cost, and is applicable to match with various gas stoves of different specifications and types.
Description
The utility model relates to a kind of gas range automatic ignition device.
The igniting of forms such as existing gas range automatic ignition device general using external power supply, battery, firestone and piezoelectric ceramics.The igniting of employing external power supply is limited by the kitchen environment condition, uses both inconvenient, also dangerous; Adopt the igniting of battery or firestone, service life is short, poor reliability; Adopting the piezoelectric ceramics igniting is comparatively advanced method, and it was both safe and reliable, and service life is also long, but is used in the piezoelectric ceramics igniter on the high-grade gas range at present, and its complex structure costs an arm and a leg, and can not generally be used on the low-grade gas range.And the piezoelectric ceramics igniter that present low-grade gas range adopted, inconvenient operation, the user will twist gas source switch on the other hand, on the other hand press button ignition switch, though controlling with a switch simultaneously of having, but service life is short, because after the igniting, its spray point burns on fire always, easy scaling loss, discharge is partly increased in the gap, and can't realize igniting.
The utility model purpose provides a kind of simple in structure, and is cheap, easy to operate, and long service life is fit to the matching used automatic ignition device of various gas ranges.
The utility model is achieved in that on existing release knob bar top makes flat side's step, pusher dog and spring are housed on it, the ratchet shifting block is equipped with at the middle part, the release knob bar is by the moving pusher dog rotation of switchboard pore area, make piezoelectric ceramics and a pawl formula slide block match and to contact with pusher dog, expansion link and spring together are contained in the adjust case, and expansion link one end is equipped with spray point, and other end telescopically contacts with the ratchet shifting block.When point is big, when the release knob bar is screwed into certain position, pawl formula slide block is under the elastic force effect of spring, and the percussive pressure electroceramics makes the widening electricity near burner igniting automatically immediately rapidly, after the igniting, ratchet shifting block and expansion link are thrown off automatically, and expansion link is return original position automatically under spring action, and spray point leaves thermal source again immediately, thereby long service life, igniting is reliable.
Below in conjunction with accompanying drawing the utility model CONSTRUCTED SPECIFICATION is described in detail.
Brief description of drawings:
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is that first kind of piezoelectric ceramics assembling is along Figure 1A-A view;
Fig. 3 is that second kind of piezoelectric ceramics assembling is along Figure 1A-A view.
The utility model is made up of piezoelectric ceramics crash device and spray point retractor device two parts.As shown in Figure 1.
The piezoelectric ceramics crash device is mainly by release knob bar (1), spring (13), seat board (18), pusher dog (5), pawl formula slide block (6) and piezoelectric ceramics (8) are formed, release knob bar (1) is to become flat side's step shape existing gas range button bar top (be switching knob below) with phenolic moulding powder or other plastic mould pressing, pusher dog (5) and compression spring (13) are housed on the flat side's step of release knob bar, release knob bar in switchboard (16) hole rotatable 90 °, and can drive the pusher dog rotation, but pusher dog longitudinal sliding motion simultaneously, the release knob bar is enclosed within copper valve (2) the spool circular hole that spring (14) is housed by switchboard (16) and seat board (18).Switchboard and seat board (18) are screwed on cast iron kitchen range face (15), because the piezo ceramic element structure difference that adopts, its piezoelectric ceramics and pawl formula slide block fixed form have two kinds.A kind of is that piezoelectric ceramics (8), pawl formula slide block (6) and spring (7) are assembled in the electronic box (17), as shown in Figure 2.Its pawl formula slide block (6) one ends and spring (7) join, and the other end contacts with piezoelectric ceramics, and pawl formula slide block can slide in electronic box.Electronic box is installed on the seat board (18).Another kind is pawl formula slide block (6) directly to be placed on the seat board and rotatable, and piezoelectric ceramics one end is fixed on the seat board (18) with pressing plate (20), and other end telescopically contacts with pawl formula slide block, as shown in Figure 3.Above-mentioned pawl formula slide block can contact with pusher dog.
The spray point retractor device is by ratchet shifting block (9), adjust case (19), and expansion link (10), compression spring (11) and spray point (12) are formed.Ratchet shifting block (9) is screwed in release knob bar (1) stage casing, adjust case (19) is screwed on the estrade of burner for gas cooker, compression spring (11) places and together is contained in the adjust case on the expansion link (10), expansion link is that round steel is made, it passes the adjust case center and borrows the spring action retractable, expansion link one end is equipped with spray point (12), and the other end can contact with ratchet shifting block (9).Spray point (12) is connected with lead with piezoelectric ceramics, and its action is synchronous.
The steel part that the utility model is used, through surface treatment, antirust ability is strong.
Operating procedure of the present utility model is: press knob and clockwise direction rotary switch button bar on the release knob bar (1) during igniting earlier, compress spring (14), imflammable gas enters copper valve (2) through ventilation duct (3), spray into burner (4), be contained in slidably also clockwise direction rotation of pusher dog (5) on the release knob bar this moment, driving pawl formula slide block (6) compresses spring (7) left, the ratchet shifting block (9) that is fixed on simultaneously on the release knob bar rotates with clockwise direction, and constantly near expansion link (10), promoting expansion link compression spring immediately stretches spray point left, when the release knob bar is screwed into certain position, when spray point and burner keep at a certain distance away, pusher dog (5) breaks away from pawl formula slide block (6), pawl formula slide block is under the elastic force effect of spring (7), rapid percussive pressure electroceramics (8), make between spray point and burner and jump out spark, fire is promptly lighted, ratchet shifting block (9) is thrown off automatically with expansion link (10) simultaneously, and its expansion link is return original position rapidly under spring (11) effect.
The utlity model has obvious advantage: the same knob of discharge switch and gas source switch, easy to operate, rely on the sensitive cooperation of spray point retractor device and piezoelectric ceramics crash device, spray point is near burner automatic ignition immediately during igniting, leave immediately again thermal source after lighting, thereby long service life, igniting is reliable. The utility model is simple in structure, and is with low cost, and applicability is wide, need not change existing gas range part, as long as load onto this device, just can realize automatic ignition. The gas range that is applicable to various different size types supports the use.
