The specific embodiment
Below in conjunction with embodiment, the utility model will be further described.
As Fig. 1, as 2, as shown in Fig. 3, the anti-handgrip of a kind of toaster presses down power-off protection mechanism, comprise movement 1, be arranged at movement one side balladeur train 3 moving up and down, be placed in switch 6, the control circuit of balladeur train downside, the base of described movement 1 is provided with electromagnet 8 and switch 6, and described electromagnet 8 is provided with inhales brandreth 802;
Described balladeur train 3 front end faces are provided with tapered end 302, one sides one depression bar 304 are set, and depression bar arranges a termination 3041, and a briquetting 5 is set on base below depression bar 304 strokes, and briquetting 5 is " T " word shape slightly, and termination 3041 has elasticity;
On described suction brandreth 802, be provided with hook 801 and pressing plate 803, the gib head of described hook 801 is partly arranged in the travel path of tapered end 302, tapered end 302 and hook 801 Elastic Contact;
Microswitch 604 is articulated on base, and microswitch 604 is control circuit power switch; Described pressing plate 803 is positioned at described microswitch 604 tops, and the free end of described microswitch 604 is arranged in the travel path of pressing plate 803;
When balladeur train 3 moves down, depression bar 304 moves down that to contact and suppress briquetting 5 descending with briquetting 5, briquetting 5 compacting pressing plates 803, and pressing plate 803 compacting microswitches 604 make its closure; After briquetting 5 puts in place, depression bar 304 continues descending elasticity steps back by briquetting 5 tops, in described briquetting 5 belows, top; The described hook 801 on brandreth 802 is inhaled in described tapered end 302 compressings, make to inhale brandreth 802 close to the iron core on described electromagnet 8, when described suction brandreth 802 approaches while touching the iron core on described electromagnet 8, described tapered end 302 is shunk back by described hook 801 tops, in described hook 801 belows.
As shown in Figure 4, described briquetting 5 is arranged in briquetting seat 502, briquetting seat 502 restriction briquettings 5 only range line from moving up and down.Range line has multiple from the mode moving up and down, what the present embodiment adopted is that briquetting seat 502 is provided with limit sliding chutes, and briquetting 5 is provided with spacer pin, and spacer pin moves in limit sliding chutes.
As shown in Figure 4, described tapered end 302 comprises slide 3022, has dead bolt 3021 and the spring 3023 of lower inclined plane, and described slide 3022 is an end opening, and the other end has the cylinder in hole; One end of described dead bolt 3021 is provided with lower inclined plane, and the other end is provided with anticreep boss; Described dead bolt 3021 is positioned at described slide 3022, and dead bolt 3021 is provided with one end of lower inclined plane through the hole on described slide 3022, and the other end contacts with spring 3023.
Described microswitch 604 arranges two.
Fig. 1, Figure 2 shows that not duty of toaster.Balladeur train 3 under the effect of stage clip 201, remain on movement 1 in above, switch 6 is in off-state, microswitch 604 one end perks are in off-state, toaster movement 1 is in off-position.
When user uses toaster baking bread, user puts into toaster bread baking groove by bread, then, when pressing down handgrip 305 and making bracket holder fixing on balladeur train 3 and balladeur train 3 bread along vertical shaft 2 down sliding, first the balladeur train compressing tablet 301 on balladeur train 3 pushes down switch press strip 601, along with continuing to press down handgrip 305, balladeur train 3 continues to move down, balladeur train compressing tablet 301 press strip 601 that compresses switch under continuing, makes switch press strip 601 rotate rocking arm 602, forces switch shrapnel 603 closures.In the process moving down at balladeur train 3, being fixed on depression bar 304 on balladeur train 3 moves down and pushes down briquetting 5, briquetting 5 is pushed down and is inhaled brandreth 802, inhale the pressing plate 803 connecting on brandreth 802 and push down again the free end of microswitch 604 perks, the free end of microswitch 604 perks is rotated down, makes microswitch 604 closures, circuit turn-on, bread baking groove energising on toaster, the iron core on described electromagnet 8 produces electromagnetic force.Simultaneously, the hook 801 on brandreth 802 is inhaled in tapered end 302 compressings fixing on balladeur train 3, make to inhale brandreth 802 close to the iron core on described electromagnet 8, when described suction brandreth 802 approaches the iron core on the described electromagnet 8 of contact, suction brandreth 802 is held, along with balladeur train 3 continues to move down, tapered end 302 continues compressing hook 801, and tapered end 302 is subject to linking up with the compressing of 801 reaction force, dead bolt 3021 compression press springs 3023 and after move, dead bolt 3021 is shunk back by linking up with 801 tops, in linking up with 801 belows.Depression bar 304 is crooked under the obstruction of briquetting 5 reaction forces, under the effect on 3041 inclined-planes, depression bar termination simultaneously, as shown in Figure 5.Balladeur train 3 continues to move down, and depression bar 304 enters the groove of briquetting 5, as shown in Figure 6.When user discharges handgrip 305, balladeur train 3 loses the pressure moving down, under the effect of spring 201 elastic force, move up, thereby, the pressing plate 803 that briquetting 5 is connected on no longer oppressing and inhaling brandreth 802 and inhale brandreth 802, but because tapered end 302 is linked up with 801 gib head below and tangled by hook 801 in inhaling on brandreth 802, thereby make balladeur train 3 and the bracket being connected on balladeur train 3 and bread remain on the bottom of toaster movement 1, toaster starts toast bread.
Toaster, under the state of toast bread, has been held by the electromagnetic force of electromagnet 8 upper cores owing to inhaling brandreth 802, thereby make to inhale pressing plate 803 on brandreth 802, pushes down microswitch 604 always and makes circuit keep conducting, and briquetting 5 no longer compresses suction brandreth 802.Limited post 7 is further to move down for limiting balladeur train 3, to avoid pushing down suction brandreth 802, when making to inhale brandreth 802 iron core be without suction after electromagnet power-off, inhale brandreth 802 and can lift certain distance, just can make to inhale the pressing plate 803 connecting on brandreth 802 and no longer oppress microswitch 604, make the free end of microswitch 604 rotate up and disconnect, thereby make whole down circuitry.
When baked bread electromagnet 8 power-off lose electromagnetic force, suction brandreth 802 can with microswitch 604 elastic force own, lift one end, makes microswitch 604 power-off.After microswitch 604 power-off, even if balladeur train 3 rests on toast bread state, even if switch 6 is still connected, heating wire is also without electric, plays the function of mechanical anti-sticking.
When baked bread electromagnet 8 power-off lose electromagnetic force, to inhale on brandreth 802 and link up with 801 not at tight hook lock head 302, balladeur train 3 rises under the effect of spring 201 spring forces, and depression bar 304 is thrown off with briquetting 5, can return to Fig. 1 state.
Change depression bar 304 into retractable movable depression bar more reliable performance, as shown in Fig. 7, Fig. 8, Fig. 9.When balladeur train 3 moves down, the termination 3041 in movable depression bar contacts with briquetting 5, and briquetting 5 is moved down.When briquetting 5 moves down while putting in place, termination 3041 compression press springs 3043 make termination 3041 retrudes, and as shown in Figure 8, balladeur train 3 continues to move down, termination 3041 move down into briquetting 5 groove time, eject as shown in Figure 9 termination 3041, briquetting 5 is pressurized no longer.After electromagnet power-off, microswitch 604 is liftable makes whole down circuitry, reaches the effect of mechanical anti-sticking.
