When the user presses the operating mechanism 20 to the switch main body 30, the lifting seat 21 pushes the main switching assembly 40 and the adjusting assembly against the emergency switching assembly 50 to connect the interiors of the main switching assembly 40 and the emergency switching assembly 50, the heating part of the toaster is located in a loop to form a passage to start heating food in the toaster, and the locking assembly 60 maintains the position relationship of the operating mechanism 20 relative to the switch main body 30 during normal heating. After the food is heated, the locking assembly 60 releases the locking of the operating mechanism 20, and then the reset traction piece drives the lifting seat 21 to move away from the switch main body 30, so that the main on-off assembly 40 and the emergency on-off assembly 50 are released to a breaking state, and the heating of the toaster is stopped. When the operating mechanism 20 is blocked and cannot move away from the switch main body 30 for resetting, the emergency button 23 is operated to release the abutting action between the adjusting component and the emergency on-off component 50, so that the emergency on-off component 50 is released and the interior is disconnected, and the current of the heating component of the toaster is cut off.

After the locking assembly 60 releases the locking of the lifting seat 21, the reset traction piece moves the lifting seat 21 in the direction away from the switch main body 30 to release the pressing of the main on-off assembly 40 and the emergency on-off assembly 50, and the current of the heating component is cut off. Specifically, the reset traction piece is a tension spring.

Further, since the emergency on-off assembly 50 is integrated in the switch main body 30, and the emergency button 23 is disposed on the lifting seat 21, when the conventional toaster without forced power-off needs to add a forced power-off function, only the upper switch main body 30 and the operating mechanism 20 need to be replaced, and the circuit layout or the housing of the toaster does not need to be adjusted too much.

Referring to fig. 2 and 3, in one embodiment, the switch main body 30 further includes a housing 70, a main button 80 movably disposed through the housing 70, and an auxiliary button 90 movably disposed through the housing 70; the main on-off assembly 40 and the emergency on-off assembly 50 are housed in the case 70; the lifting seat 21 presses the main on-off component 40 through the main button 80; the adjustment assembly is pressed against the hard on-off assembly 50 by the secondary button 90.

By accommodating the main on-off assembly 40 and the emergency on-off assembly 50 in the housing 70 made of an insulating material, the metal parts of the main on-off assembly 40 or the emergency on-off assembly 50 can be effectively prevented from generating electric leakage. The operating mechanism 20 acts on the part of the main button 80 or the sub button 90 made of an insulating material exposed out of the case 70, so that it is not necessary to directly contact the main switching unit 40 or the emergency switching unit 50, and the safety of electricity utilization is improved.

Further, to improve the structural stability of the switch main body 30, the latch assembly 60 is housed in the housing 70; in other embodiments, the main and emergency on/off assemblies 40 and 50 may also be housed in an enclosed space formed by the toaster case.

Referring to fig. 2, in one embodiment, the lifting seat 21 is provided with a fixed pushing portion 211, and the fixed pushing portion 211 is used for pushing the main button 80; the adjusting component comprises a toggle piece 221 pivoted with the lifting seat 21 and a first elastic piece 224 connected with the toggle piece 221, and the first elastic piece 224 enables the toggle piece 221 to maintain a preset angle relative to the lifting seat 21 through an emergency button; the emergency button 23 is connected with the dial piece 221; the dial 221 is provided with a movable pressing portion 222 for pressing the sub button 90.

When the lifting base 21 moves close to the switch main body 30, the first elastic member 224 keeps the angle of the toggle member 221 relative to the lifting base 21 constant, and the fixed pressing portion 211 and the movable pressing portion 222 respectively press the main button 80 and the sub-button 90, so that the main on-off assembly 40 and the emergency on-off assembly 50 are switched to the on state by the mechanical action. When the lifting seat 21 cannot move due to the blockage of food, the emergency button 23 moves to drive the toggle piece 221 to deflect relative to the lifting seat 21, after the angle of the toggle piece 221 is adjusted, the movable pushing part 222 leaves the auxiliary button 90, the pressing of the emergency on-off component 50 is released, the emergency on-off component 50 is restored to the breaking state, and the loop of the heating component is cut off.

Referring to fig. 2, in one embodiment, the emergency button 23 is located on a side of the fixing handle 212 close to the switch main body 30; the first elastic member 224 abuts between the fixing handle 212 and the emergency button 23. The fixing handle 212 is pushed towards the switch main body 30 to drive the lifting seat 21 and the adjusting component to move; since the panic button 23 is located on the side of the fixed handle 212 close to the switch body 30, erroneous activation of the panic button 23 when the fixed handle 212 is operated can be avoided.

Since the first elastic member 224 enables the dial 221 to automatically reset to a predetermined angle, the reset of the dial 221 drives the reset of the emergency button 23. After the food that blocks in the toaster is cleared away, the traction piece that resets drives lift seat 21 to reset to the position of keeping away from switch main body 30, and emergency button 23 and dial piece 221 are reset by the effect of first elastic component 224 simultaneously, need not to carry out other adjustments to emergency button 23 or adjusting part when needing to put through the heating circuit next time, only need bulldoze fixed handle 212 can to the use operation that can simplify the switch.

Specifically, the first elastic element 224 is a compression spring and is accommodated in the fixing handle 212 and the emergency button 23; to further reduce false triggering of the panic button 23, the panic button 23 is partially housed in the stationary handle 212. The toggle member 221 is provided with a positioning block 223, and the first elastic member 224 pushes the toggle member 221 until the positioning block 223 abuts against the lifting seat 21, so that the angle between the toggle member 221 and the lifting seat 21 is kept stable.

Referring to fig. 8, in one embodiment, the lifting seat 21 is provided with a fixed pushing portion 211, and the fixed pushing portion 211 is used for pushing the main button 80; the adjusting assembly comprises a sliding member 225 slidably connected with the lifting seat 21 and a second elastic member 226 abutting against the sliding member 225, wherein the second elastic member 226 is used for maintaining the sliding member 225 at a preset position relative to the lifting seat 21; the emergency button 23 abuts the glide 225; the slider 225 is provided with a movable pressing portion 222 for pressing the sub-button 90.

When the lifting base 21 moves close to the switch main body 30, the second elastic member 226 keeps the sliding member 225 at a predetermined position relative to the lifting base 21, the fixed pushing part 211 and the movable pushing part 222 respectively push the main button 80 and the sub button 90, and the main on-off assembly 40 and the emergency on-off assembly 50 are switched to the on state by mechanical action. When the lifting seat 21 cannot move due to the blockage of food, the emergency button 23 moves to drive the sliding piece 225 to move relative to the lifting seat 21 and the auxiliary button 90, and when the position of the sliding piece 225 changes, the movable pushing part 222 leaves the auxiliary button 90, the pressing of the emergency on-off component 50 is released, the emergency on-off component 50 is recovered to be in the breaking state, and the loop of the heating component is cut off.

The second elastic member 226 can automatically reset the sliding member 225 to a predetermined position, and the reset of the sliding member 225 drives the reset of the emergency button 23. After the food that blocks in the toaster is cleared away, the traction piece that resets drives lift seat 21 to reset to the position of keeping away from switch main part 30, and emergency button 23 and sliding piece 225 are reset by the effect of second elastic component 226 simultaneously, need not to carry out other adjustments to emergency button 23 or adjusting part when needing to put through the heating circuit next time, only need bulldoze fixed handle 212 can to the use operation of switch can be simplified.

Referring to fig. 8, in one embodiment, one of the lifting seat 21 and the sliding member 225 has a sliding slot 213, and the other has a sliding block 227; the sliding block 227 is movably accommodated in the sliding groove 213; the second elastic member 226 abuts between the lifting seat 21 and the sliding member 225. Because the emergency button 23 moves along with the sliding piece 225, and the emergency button 23 movably penetrates through the fixed handle 212, at least one side of the emergency button 23 is covered by the fixed handle 212, thereby reducing the chance of false triggering of the emergency button 23 when the fixed handle 212 is operated. The sliding groove 213 extends in a direction perpendicular to the moving direction of the lifting base 21, so that the resistance applied when the emergency button 23 or the sliding member 225 is pushed can be minimized.

The lifting seat 21 is provided with a fixed pushing part 211, and the fixed pushing part 211 is used for pushing the main button 80; the adjusting component is provided with a movable pushing part 222, and the movable pushing part 222 is used for pushing the auxiliary button 90; before the operating mechanism 20 contacts the switch main body 30, the distance between the fixed pressing portion 211 and the main button 80 is greater than the distance between the movable pressing portion 222 and the sub-button 90.

When the heating component is needed to be switched on, the time when the movable pushing part 222 contacts the auxiliary button 90 is earlier than the time when the fixed pushing part 211 contacts the main button 80 along with the movement of the lifting seat 21 close to the switch main body 30; when the circuit of the heating component needs to be cut off, along with the movement of the lifting seat 21 away from the switch main body 30, the time that the movable pushing part 222 leaves the auxiliary button 90 is later than the time that the fixed pushing part 211 leaves the main button 80, so that the emergency on-off component 50 can be prevented from being directly used for cutting off the current, the electric arc generated in the emergency on-off component 50 can be prevented, the good breaking capacity of the emergency on-off component 50 can be maintained, and the current of the heating component can be reliably cut off in the emergency situation.

Referring to fig. 5 and 6, in one embodiment, the main switching assembly 40 includes a first side pin conductive plate 41 connected to the housing 70, a middle pin conductive plate 42 connected to the housing 70, and a first movable contact 43 movably disposed in the housing 70; the first movable contact piece 43 makes the first edge pin conducting piece 41 and the middle pin conducting piece 42 switch between electrical connection and electrical isolation through movement, and the movement of the first movable contact piece 43 is driven by the main button 80; the emergency on-off assembly 50 comprises a second side pin conducting strip 51 connected with the shell 70 and a second movable contact piece 52 movably arranged in the shell 70; the second movable contact piece 52 makes the second side pin conducting piece 51 and the middle pin conducting piece 42 switch between electrical connection and electrical isolation through activity, and the activity of the second movable contact piece 52 is driven by the auxiliary button 90.

When the loop of the heating component needs to be connected, the first side pin conducting strip 41, the first moving contact strip 43, the middle pin conducting strip 42, the second moving contact strip 52 and the second side pin conducting strip 51 are sequentially contacted and connected in series in the loop between the heating component and the power supply, so that current can pass through the heating component. When the circuit of the heating element needs to be cut off, the lifting seat 21 moves away from the switch main body 30, the main button 80 drives the first movable contact piece 43 to leave the first side pin conducting piece 41 or the middle pin conducting piece 42, and at the same time or after that, the auxiliary button 90 drives the second movable contact piece 52 to leave the second side pin conducting piece 51 or the middle pin conducting piece 42, so that electrical isolation is generated.

Specifically, the first temple conducting strip 41, the middle temple conducting strip 42, the first movable contact strip 43, the second temple conducting strip 51 and the second movable contact strip 52 are made of metal or alloy, preferably, red copper.

Referring to fig. 5 and 6, in one embodiment, the first movable contact 43 is abutted with the first edge conducting strip 41 or the first movable contact 43 is abutted with the middle conducting strip 42 through a contact; the second movable contact piece 52 is butted with the middle pin conducting piece 42 or the second movable contact piece 52 is butted with the second side pin conducting piece 51 through contact points. Thereby improving the electrical conductivity of the main and emergency on-off assemblies 40 and 50 and reducing the oxidation rate.

Referring to fig. 3 and 4, in one embodiment, the first movable contact piece 43 and the second movable contact piece 52 are kept in contact with the middle pin conducting piece 42 during the moving process. Therefore, the connection or disconnection of the main switching assembly 40 is determined by the distance between the first temple conductive piece 41 and the first movable contact piece 43, and the connection or disconnection of the emergency switching assembly 50 is determined by the gap between the second temple conductive piece 51 and the second movable contact piece 52, so that the structure of the switch main body 30 can be simplified.

Referring to fig. 5 and 6, in one embodiment, the main button 80 has a first side portion 81, and the first side portion 81 has an inclined surface; the switch main body 30 further includes a first abutting elastic piece 82 for abutting the first movable contact piece 43 to the first side extension 81; the inclined surface on the first side extension part 81 is used for guiding the first movable contact piece 43 to abut against the middle pin conducting strip 42; the sub-button 90 has a second side extension 91, and the second side extension 91 has an inclined surface; the switch main body 30 further includes a second abutting elastic piece 92 for abutting the second movable contact piece 52 to the second side extension 91; the inclined surface on the second side extension 91 serves to guide the second movable contact piece 52 into abutment with the center leg conductive piece 42.

By adjusting the direction of the inclined surface, the side close to the middle pin conductive piece 42 is lower, so that the first side portion 81 and the second side portion 91 respectively guide the angles of the first movable contact piece 43 and the second movable contact piece 52, and the first movable contact piece 43 and the second movable contact piece 52 can respectively contact with the middle pin conductive piece 42 before being pressed by the operating mechanism 20, thereby simplifying the installation of the first movable contact piece 43 and the second movable contact piece 52. In addition, since the first movable contact piece 43 and the second movable contact piece 52 are separately connected to the middle pin conductive piece 42 and can be kept in contact with the middle pin conductive piece 42, the thickness of the first movable contact piece 43 and the second movable contact piece 52 can be increased without considering the problem of ensuring the elastic moving range, for example, a metal piece with a thickness of 0.8mm or more can be used to increase the maximum allowable current of the main on-off assembly 40 or the emergency on-off assembly 50.

Referring to fig. 5, in one embodiment, a first clip extends from a side of the first movable contact 43 opposite to the first side portion 81, and one end of the first abutting elastic element 82 abuts against the first clip; a second clip 53 extends from a side of the second movable contact piece 52 facing away from the second side portion 91, and one end of the second abutting elastic piece 92 abuts against the second clip 53. The first abutting elastic member 82 is a compression spring, and two ends of the first abutting elastic member abut against the main button 80 and the first clip respectively, so that the first movable contact piece 43 can actively slide along the inclined plane to the middle pin conductive member. The second abutting elastic element 92 is a compression spring, and two ends of the second abutting elastic element respectively abut against the auxiliary button 90 and the second clip 53, so that the second movable contact piece 52 can actively slide along the inclined plane to the middle pin conductive element.

Referring to fig. 5 and 6, in one embodiment, the main button 80 further has a first side hook 83 connected to the first side portion 81, and the first movable contact 43 is accommodated between the first side hook 83 and the main body of the main button 80; the sub-button 90 further has a second side hook 93 connected to the second side portion 91, and the second movable contact 52 is accommodated between the second side hook 93 and the main body of the sub-button 90. So that the first movable contact piece 43 is prevented from being released from the main button 80 or the second movable contact piece 52 is prevented from being released from the sub button 90.

Referring to fig. 5, in one embodiment, a cambered groove 421 is formed on the middle pin conductive sheet 42; the first movable contact piece 43 or the second movable contact piece 52 is provided with a V-shaped part 431, and the convex side of the V-shaped part 431 is attached to the surface of the cambered groove 421; the ribbed feature of the housing 70 extends into the concave side of the V-shaped portion 431. Through the contact fit of the arc groove 421 and the V-shaped portion 431, the first movable contact piece 43 or the second movable contact piece 52 can be kept in full contact with the middle pin conducting strip 42 in the moving process, so that the resistance is reduced; the extension of the rib feature of the housing 70 to the concave side of the V-shaped portion 431 can limit the moving range of the first movable contact piece 43 or the second movable contact piece 52, and can facilitate the assembly of the switch main body 30, avoiding the need to pivotally connect the first movable contact piece 43 or the second movable contact piece 52 with the middle pin conductive member.

Referring to fig. 6, in one embodiment, the main switching assembly 40 includes a third leg conductive member 45 connected to the housing 70, a fourth leg conductive member 46 connected to the housing 70, and a third movable contact 47 movably disposed in the housing 70; the third movable contact piece 47 switches the third leg conductive member 45 and the fourth leg conductive member 46 between electrical connection and electrical isolation by moving, and the movement of the third movable contact piece 47 is driven by the main button 80. One end of the heating element is connected to the phase line of the power supply through the first and second leg conductive pieces 41 and 51, and the other end is connected to the zero line of the power supply through the third and fourth leg conductive pieces 45 and 46, thereby ensuring that the heating element can be reliably isolated from the power supply in the power-off state.

Further, the movable ranges of the first movable contact piece 43, the second movable contact piece 52 and the third movable contact piece 47 are arranged in parallel to each other, so that the first movable contact piece 43, the second movable contact piece 52 and the third movable contact piece 47 are arranged in parallel to each other, thereby reducing the volume of the switch main body.

Referring to fig. 3 and 5, in one embodiment, the switch main body 30 further includes a third elastic member 72, and the third elastic member 72 is used for moving the main button 80 or the sub button 90 along the reset direction of the operating mechanism 20. After the lifting seat 21 and the adjusting assembly release the pressing of the main button 80 or the auxiliary button 90, the elastic force of the third elastic element 72 pushes and presses the main button 80 or the auxiliary button 90 in the opposite direction, so as to drive the first movable contact piece 43 to leave the first edge conducting strip 41 or the second movable contact piece 52 to leave the second edge conducting strip 51, and the main switching assembly 40 and the emergency switching assembly 50 are restored to be disconnected in time.

Referring to fig. 3, in one embodiment, an orientation pin 71 extends in the housing 70, and the orientation pin 71 penetrates through the primary button 80 or the secondary button 90; the third elastic member 72 is fitted over the orientation pin 71. The main button 80 or the auxiliary button 90 is provided with the orientation pin 71 in a penetrating way, so that the moving direction of the main button 80 or the auxiliary button 90 can be limited, and dislocation is avoided.

Referring to fig. 2, in one embodiment, the lifting seat 21 has a hook portion 214; the locking assembly 60 comprises an electromagnetic piece 61 connected with the housing 70 and an armature piece 62 movably connected with the housing 70; the electromagnetic piece 61 is used for attracting the armature piece 62 to lock the position or the angle of the armature piece 62; the armature member 62 has a hook portion 621, and the hook portion 621 engages with the hook receiving portion 214 to lock the lifting base 21 at a position close to the switch main body 30. Therefore, the position of the armature piece 62 can be locked by controlling the magnetic force of the electromagnetic piece 61, and when the position of the armature piece 62 is locked, the hook part 621 abuts against the hook bearing part 214 to prevent the lifting seat 21 from being reset by the reset traction piece, and the pressing of the operating mechanism 20 on the main button 80 and the auxiliary button 90 is kept.

Referring to fig. 2, the hook portion 214 and the hook portion 621 have V-shaped side sections, respectively. Therefore, the weight of the hook part 214 and the hook part 621 can be reduced, and the extension angle of the hook part 214 and the hook part 621 can be adjusted, for example, the included angle between the inclined surface of the hook part 621 facing the hook part 214 and the moving direction of the hook part 214 can be reduced, so that the resistance when the hook part 214 is fastened to the hook part 621 can be reduced. Specifically, when the lifting base 21 moves closer to the switch main body 30 before the electromagnetic member 61 generates the magnetic force, the hook receiving portion 214 abuts against the hook portion 621, and then the armature member 62 deflects while the hook portion 621 swings in a direction away from the electromagnetic member 61. After the hook-receiving portion 214 moves to the proper position, the hook 621 abuts against the concave side of the hook-receiving portion 214, and at the same time, the electromagnetic member 61 generates magnetic force, and the position or direction of the armature member 62 is locked, thereby locking the positions of the hook-receiving portion 214 and the lifting seat 21.

The hook-bearing part 214 is provided with a first abutting surface, the hook part 621 is provided with a second abutting surface, and the first abutting surface and the second abutting surface are parallel or approximately parallel; when the lifting seat 21 is locked at a position close to the switch main body 30, the first abutting surface is attached to the second abutting surface; the axial direction of the slide rod is perpendicular or nearly perpendicular to the first abutting surface or the second abutting surface. By utilizing the component force in the axial direction of the slide bar when the first abutting surface and the second abutting surface abut against each other, the suction force required when the electromagnetic member 61 locks the lifting base 21 can be reduced.

Referring to fig. 4 and 5, in one embodiment, the locking assembly 60 further includes a fourth elastic member 63; the fourth elastic member 63 is used to move the hook 621 of the armature member 62 in a direction to approach the armature member 62. The fourth elastic member 63 allows the armature member 62 to actively abut against the electromagnetic member 61, thereby preventing the fixed armature member 62 from being unable to be attracted due to an excessively large gap between the armature member 62 and the electromagnetic member 61.

Specifically, a deflection fulcrum 73 extends in the housing 70, and the deflection fulcrum 73 is positioned on the side of the armature member 62 opposite to the electromagnet; the fourth elastic member 63 is a compression spring, two ends of the fourth elastic member 63 respectively abut against the armature member 62 and the inner wall of the housing 70, the abutting part of the armature member 62 and the fourth elastic member 63 is located on one side of the deflection fulcrum 73, the hook portion 621 is located on the other side of the deflection fulcrum 73, under the lever action, the fourth elastic member 63 drives the armature member 62 to deflect, and the hook portion 621 moves towards the direction close to the armature member 62.

In this embodiment, when the operating mechanism 20 is blocked and cannot move away from the switch main body 30 to reset, the emergency button 23 is operated to release the abutting action between the adjusting assembly and the emergency on-off assembly 50, so that the emergency on-off assembly 50 is released and the interior is disconnected, and the current of the heating component of the toaster is cut off. Since the emergency opening and closing member 50 is integrated in the switch main body 30, the cable connection relationship in the toaster can be simplified and the assembly efficiency of the toaster can be improved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
