Detailed description of the invention:
The combination safety switch of toaster, comprises lifting handle, crane, depression bar, switch frame, magnetic adsorption plate, electromagnet, two electroconductive elastic sheets, four conductive contacts and pcb boards and some electronic devices and components and forms.
As shown in Fig. 1-3,9, lifting handle 1 is arranged on crane 2 and drives crane 2 to slide up and down, depression bar 3 is arranged on the first axle 12 of crane 2 by the first hole 13, crane 2 is enclosed within the axis of guide 10, and the axis of guide 10 driving crane 2 and depression bar 3 to arrange along the longitudinal by lifting handle 1 slides up and down.
Depression bar 3 lower end is provided with thin slice 15, crane 2 is provided with muscles and bones 11 and can carries out in the region of top spacing lower muscles and bones 14, first axle 12 between upper muscles and bones 11 and lower muscles and bones 14 thin slice 15.
Magnetic adsorption plate 5 is contained in switch frame 4 li, the bottom surface of magnetic adsorption plate 5 contacts with the flange 16 of the laterally extending by sidewall of switch frame 4, switch frame 4 is enclosed within the second axle 18 of electromagnet 6 by second hole 17 on both sides, two conductive contacts 8 are riveted on an electroconductive elastic sheet back side respectively, connecting and disconnecting of the circuit parts include two electroconductive elastic sheets 7, two electroconductive elastic sheets 7, another two conductive contacts 8 and electromagnet 6 are fixed on pcb board 9 by soldering mode, and switch frame 4 rotates around the center in the second hole 17 around the second axle 18 of electromagnet 6.
As shown in Figure 2, described electroconductive elastic sheet 7 is when free state, and electroconductive elastic sheet lower end 24 adopts outwards sticks up structure; Electroconductive elastic sheet 7 is provided with electroconductive elastic sheet projection 22; The back side of switch frame 4 bottom is provided with the inner side muscles and bones 23 that can be connected with electroconductive elastic sheet projection 22; The lower sidewall of the close depression bar 3 of switch frame 4 is provided with inclined-plane 26, outside, and top is provided with snap fit 25.
When the switch activating mechanism of composition such as part such as crane 2 grade does not touch switch frame 4, lower end due to electroconductive elastic sheet 7 tilts, at this moment corresponding pair of conductive contact 8 is separated, be in off-position, electroconductive elastic sheet projection 22 withstands the inner side muscles and bones 23 of switch frame 4 simultaneously, make the inclined-plane, outside 26 of switch frame protruding, the snap fit 25 of top is then towards layback.
Depression bar 3 includes upper end projection 19 and depression bar lower end 20, extends respectively and formed from the first hole 13.
As shown in Figure 3, the outside hypotenuse 26 of switch frame 4 is withstood in the depression bar lower end 20 that lifting handle 1 drives crane 2 and depression bar 3 to move down into depression bar 3, at this moment switch frame 4 drives magnetic adsorption plate 5 to rotate around the second axle 18 of electromagnet 6, the inner side muscles and bones 23 of switch frame 4 extrudes electroconductive elastic sheet projection 22, electroconductive elastic sheet lower end 24 is allowed to be out of shape, conductive contact 8 on electroconductive elastic sheet 7 is contacted with the conductive contact 8 be fixed on pcb board 9, circuit turn-on, the top 21 of electromagnet 6 produces magnetic attraction simultaneously, and magnetic adsorption plate 5 is adsorbed by the top 21 of electromagnet 6.
As shown in Figure 3-4, when lifting handle continues to press downwards, the rotation around the second hole 17 due to switch frame 4 causes outside hypotenuse 26 slope of lower end to become large, and depression bar 3 rotates around the first axle 12 of crane 2, depression bar lower end 20 is skidded off, the contact of the outside hypotenuse 26 of final disengaging and switch frame 4 from the outside hypotenuse 26 of switch frame 4.
As in Figure 3-5, due to the magnetic attraction of electromagnet 6, magnetic adsorption plate 5 is continued to be absorbed and fixed on the top 21 of electromagnet 6, and the flange 16 on switch frame 4 both sides is pushed down on the both sides of magnetic adsorption plate 5, switch frame 4 is fixed, so the inner side muscles and bones 23 of switch frame 4 extrudes electroconductive elastic sheet projection 22, and allow conductive contact 8 continue contact, circuit keeps conducting.
As shown in Figure 5, because switch frame 4 is around the rotation in the second hole 17, make to move outside the snap fit 25 of its upper end, after the downforce of lifting handle 1 disappears, crane 2 under the effect of machine lifting mechanism on when moving, the upper end projection 19 of depression bar 3 will be blocked by the snap fit 25 of switch frame 4, makes crane 2 can not up movement again, thus the position making rusk suitable in machine baking, complete the using function of machine.
As shown in Fig. 2,7,8, after the baking time of machine setting terminates, the magnetic attraction on the top 21 of electromagnet 6 disappears, and can not continue to adsorb fixing magnetic adsorption plate 5, the pressure of both sides to the flange 16 on switch frame 4 both sides of magnetic adsorption plate 5 also disappears.So the inner side muscles and bones 23 of switch frame 4 cannot continue to apply extruding force to electroconductive elastic sheet protruding 22, and electroconductive elastic sheet 7 recovers shape, allows conductive contact 8 disengage, and circuit disconnects.Simultaneously electroconductive elastic sheet projection 22 withstands the inner side muscles and bones 23 of switch frame 4, makes to rotate from switch frame 4 around the second hole 17, moves, can not pin the upper end projection 19 of depression bar 3 again after the snap fit 25 of its upper end can deflect.Such crane just freely can go up horizontal reset, and machine completes the work of bread baking.
As shown in Fig. 4 and Fig. 6, when lifting handle 1 continue descending and push down time, because the outside hypotenuse 26 of depression bar lower end 20 from switch frame 4 skids off, depart from the contact with the outside hypotenuse 26 of switch frame 4, after the baking time of machine setting terminates, electromagnet 6 top 21 on magnetic attraction disappear, fixing magnetic adsorption plate 5 can not be adsorbed, the both sides of magnetic adsorption plate 5 lose the pressure of the flange 16 to switch frame 4 both sides, the extruding force of inner side muscles and bones 23 pairs of electroconductive elastic sheet projections 22 of switch frame 4 also disappears, electroconductive elastic sheet 7 recovers shape, conductive contact 8 is allowed to disengage, circuit can disconnect.
As shown in Figure 1, the material selection nylon material of crane 2 or other heat-resisting and less material of coefficient of friction are made, upper muscles and bones 11 can prevent depression bar 3 from rotating through many around the first axle 12 of crane 2, the setting of the lower muscles and bones 14 of crane 2 is to withstand depression bar 3 when the snap fit 25 of switch frame 4 pins the upper end projection 19 of depression bar 3, make it can not continue to rotate around the first axle 12, and the thin slice 15 that can withstand on depression bar 3, location restore when making its free state.The material selection nylon material of depression bar 3 or other heat-resisting and less material of coefficient of friction are made, and thin slice 15 thickness about 0.5 ~ 0.8mm, can have certain elastic force, can easily be out of shape, and depression bar 3 also can be made to recover position.The material selection nylon material of switch frame 4 or other heat-resisting and less material of coefficient of friction are made, the iron plate of the material selection thickness 1.2 ~ 2mm of magnetic adsorption plate 5, the material of electroconductive elastic sheet 7 selects copper sheet or the stainless steel substrates of thickness 0.3 ~ 0.4mm, conductive contact 8 adopts the silver-plated contact of copper, the shape that the material of lifting handle 1 can select different material and designs to become different as required.The axis of guide selects iron staff chromium plating or the stainless steel bar of diameter 3.5 ~ 4mm.
In sum, toaster structure provided by the present invention, can make machine still circuit the two poles of the earth can be disconnected simultaneously when outside lifting handle is held down, and ensures use safety, can reduce the manufacturing cost of manufacturer, improve the competitiveness of product significantly.
During toaster work of the present invention, crane 2 slide downward is driven when lifting handle 1 presses down, depression bar 3 is pushed down outside switch frame 4 lower end makes it rotate inside pcb board 9, thus the inner side muscles and bones 23 pairs of electroconductive elastic sheets 7 inside switch frame 4 lower end apply pressure makes it be out of shape to allow two pairs of conductive contacts contacts cause circuit ON, meanwhile electromagnet 6 produces electromagnetic attraction and holds magnetic adsorption plate 5, so magnetic adsorption plate 5 push down switch frame 4 make its be fixedly maintained electroconductive elastic sheet 7 be out of shape state, and make circuit continue connect until electromagnet 6 magnetic force disappear.At this moment when crane 2 continues to press down, depression bar 3 rotates and skids off from switch frame 4, and no longer exert a force to switch frame 4, the snap fit 25 of switch frame 4 top then can catch on depression bar upper end 19 makes crane 2 pin, and rusk is toasted in flue.
After toaster was finished the work according to the time arranged, the magnetic attraction of electromagnet 6 disappears, and magnetic adsorption plate 5 can not push down switch frame 4, and the pressure of switch frame 4 pairs of electroconductive elastic sheets 7 also disappears, and the distortion of electroconductive elastic sheet 7 will recover, and two pairs of conductive contacts disengage, and circuit disconnects.The pulling force of snap fit 25 pairs of depression bars 3 of Simultaneous Switching frame 4 also disappears, and the spring band that crane 2 can be lifted mechanism moves upward sliding, and rusk is ejected from flue.
The structure of this toaster can still can disconnecting circuit when lifting handle is held down, and ensures use safety.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
