Description

Technical Field

[0001] The present invention relates to the technical field of electrical switches, and particularly to a self - restoring integrated forced - power - off toaster switch. Background Art

[0002] A toaster, also known as an automatic bread - slicing toaster or bread roaster in China, is an electric cooking appliance specifically used for re - baking sliced bread. With the accelerating pace of life, more people rely on this small appliance. It can not only toast bread slices to a golden - brown color but also make their fragrance stronger and taste better, enhancing appetite. Toasters have the advantages of being small in size, convenient to use, and energy - saving.

[0003] Existing toasters generally have an operating handle on one side that is adjusted by pressing down. When the operating handle is depressed, the normally - open contact of the internal switch is closed, and the toaster starts heating. Through internal delay control, after the heating is completed, the operating handle is automatically released, and at the same time, the normally - open contact is disconnected. Since the operating handle moves synchronously with the lifting frame inside the toaster, when the lifting frame inside the toaster is blocked by food and the operating handle cannot be released, the toaster will continue to heat. To avoid accidents and meet the requirements of safety regulations, existing toasters generally additionally install an emergency switch to forcibly cut off the power of the toaster. However, setting multiple switches inside the toaster will increase the connection of the toaster's cables and make the assembly steps of the toaster cumbersome. Summary of the Invention

[0004] Based on this, in view of the problem that the additional emergency switch installed in the toaster increases the connection of the toaster's cables and makes the assembly steps of the toaster cumbersome, it is necessary to provide a self - restoring integrated forced - power - off toaster switch.

[0005] A self - restoring integrated forced - power - off toaster switch is applied to a toaster. The toaster has a frame body and a heating circuit with a heating component. The frame body is provided with a sliding rod and a reset traction member. The self - restoring integrated forced - power - off toaster switch includes:

[0006] An operating mechanism, which includes a lifting seat slidably connected to the sliding rod, a fixed handle connected to the lifting seat, an emergency button accommodated in the fixed handle, and an adjusting component accommodated in the lifting seat; the lifting seat is driven by the reset traction member to reset.

[0007] Switch body, the switch body includes a main on-off component, an emergency on-off component, and a locking component; the main on-off component and the emergency on-off component are connected in series in the heating circuit; when the lifting seat is driven by the fixed handle to move closer to the switch body, the lifting seat presses the main on-off component, and the adjusting component presses the emergency on-off component, so that the main on-off component and the emergency on-off component are turned on; the locking component is used to maintain the position of the operating mechanism relative to the switch body; the emergency button is used to release the pressing on the emergency on-off component through the adjusting component.

[0008] In the above self-resetting integrated forced power-off toaster switch, the main on-off component and the emergency on-off component are connected in series in the heating circuit. When the user presses the operating mechanism towards the switch body, the lifting seat presses the main on-off component, and the adjusting component presses the emergency on-off component correspondingly, so that the inside of the main on-off component and the emergency on-off component is turned on, and the circuit where the heating component of the toaster is located forms a path, and the food in the toaster starts to be heated. The locking component maintains the positional relationship between the operating mechanism and the switch body during normal heating. After the food is heated, the locking component releases the locking of the operating mechanism, and then the reset traction member drives the lifting seat to move away from the switch body, so that the main on-off component and the emergency on-off component are released to the off state, and the heating of the toaster stops. When the operating mechanism is blocked and cannot move and reset away from the switch body, by operating the emergency button, the abutting effect between the adjusting component and the emergency on-off component is released, so that the emergency on-off component is released and internally disconnected, and the current of the heating component of the toaster is cut off. Since the emergency on-off component is integrated in the switch body, the cable connection relationship inside the toaster can be simplified, and at the same time, the assembly efficiency of the toaster can be improved.

[0009] In one embodiment, the switch body further includes a housing, a main button movably passing through the housing, and a sub-button movably passing through the housing; the main on-off component and the emergency on-off component are accommodated in the housing; the lifting seat presses the main on-off component through the main button; the adjusting component presses the emergency on-off component through the sub-button; thereby improving the electrical safety.

[0010] In one embodiment, the lifting seat is provided with a fixed pressing part for pressing the main button; the adjusting component includes a rotating part pivotally connected to the lifting seat and a first elastic part connecting the rotating part. The first elastic part makes the rotating part maintain a predetermined angle relative to the lifting seat through the emergency button; the emergency button is connected to the rotating part; the rotating part is provided with a movable pressing part for pressing the sub-button; thereby the circuit of the heating component can be cut off.

[0011] In one embodiment, the lifting seat is provided with a fixed pressing part for pressing the main button; the adjusting assembly includes a sliding member slidably connected to the lifting seat and a second elastic member abutting against the sliding member, and the second elastic member is used to maintain the sliding member at a predetermined position relative to the lifting seat; the emergency button abuts against the sliding member; the sliding member is provided with a movable pressing part for pressing the sub-button; thereby, the circuit of the heating component can be cut off.

[0012] In one embodiment, the lifting seat is provided with a fixed pressing part for pressing the main button; the adjusting assembly is provided with a movable pressing part for pressing the sub-button; before the operating mechanism contacts the switch body, the distance between the fixed pressing part and the main button is greater than the distance between the movable pressing part and the sub-button; thereby, the good breaking ability of the emergency on-off assembly can be maintained to reliably cut off the current of the heating component in an emergency.

[0013] In one embodiment, the main on-off assembly includes a first side-foot conductive sheet connected to the housing, a middle-foot conductive sheet connected to the housing, and a first moving contact movably arranged in the housing; the first moving contact enables the first side-foot conductive sheet and the middle-foot conductive sheet to switch between electrical connection and electrical isolation through movement, and the movement of the first moving contact is driven by the main button; the emergency on-off assembly includes a second side-foot conductive sheet connected to the housing and a second moving contact movably arranged in the housing; the second moving contact enables the second side-foot conductive sheet and the middle-foot conductive sheet to switch between electrical connection and electrical isolation through movement, and the movement of the second moving contact is driven by the sub-button; thereby, the circuit where the heating component of the toaster is located can be connected or disconnected.

[0014] In one embodiment, the main on-off assembly includes a third side-foot conductive member connected to the housing, a fourth side-foot conductive member connected to the housing, and a third moving contact movably arranged in the housing; the third moving contact enables the third side-foot conductive sheet and the fourth side-foot conductive member to switch between electrical connection and electrical isolation through movement, and the movement of the third moving contact is driven by the main button; thereby, it can be ensured that the heating component can be reliably isolated from the power supply in a power-off state.

[0015] In one embodiment, the switch body further includes a third elastic member for moving the main button or the sub-button along the reset direction of the operating mechanism, so that the main on-off component and the emergency on-off component can be restored to the off state in time. A positioning pin extends in the housing and passes through the main button or the sub-button. The third elastic member is sleeved on the positioning pin to limit the moving direction of the main button or the sub-button and prevent dislocation.

[0016] In one embodiment, the lifting seat has a hook portion. The locking assembly includes an electromagnetic member connected to the housing and an armature member movably connected to the housing. The electromagnetic member is used to attract the armature member to lock the position or angle of the armature member. The armature member has a hook portion that cooperates with the hook portion to lock the lifting seat in a position close to the switch body, thereby preventing the lifting seat from being driven by the reset traction member to reset and maintaining the pressing of the operating mechanism on the main button and the sub-button.

[0017] In one embodiment, it is characterized by including at least one of the following technical features:

[0018] The hook portion is provided with a first abutting surface, and the hook portion is provided with a second abutting surface. The first abutting surface and the second abutting surface are arranged parallel or nearly parallel. When the lifting seat is locked in a position close to the switch body, the first abutting surface and the second abutting surface are in contact with each other. The axial direction of the sliding rod is perpendicular or nearly perpendicular to the first abutting surface or the second abutting surface, which can reduce the suction force required for the electromagnetic member to lock the lifting seat.

[0019] The locking assembly further includes a fourth elastic member for moving the hook portion of the armature member towards the armature member to avoid the inability to attract and fix the armature member due to excessive clearance between the armature member and the electromagnetic member.

[0036] Please refer to Figures 1 to 8 , a self - reset integrated forced - power - off toaster switch 100 according to an embodiment of the present invention, which is applied to a toaster. The toaster has a frame and a heating circuit with a heating component. The frame is provided with a sliding rod and a reset traction member. The switch is used to connect the heating circuit in the toaster and can cut off the heating circuit in the toaster in case of an accident. The self - reset integrated forced - power - off toaster switch 100 includes: an operating mechanism 20 and a switch body 30; the operating mechanism 20 includes a lifting seat 21 slidably connected to the toaster frame, a fixed handle 212 connected to the lifting seat 21, an emergency button 23 accommodated in the fixed handle 212, and an adjusting component accommodated in the lifting seat 21; the lifting seat 21 is driven to reset by the reset traction member; the switch body 30 includes a main on - off component 40, an emergency on - off component 50, and a locking component 60; the main on - off component 40 and the emergency on - off component 50 are connected in series in the heating circuit; when the lifting seat 21 is driven by the fixed handle 212 to move closer to the switch body 30, the lifting seat 21 presses the main on - off component 40, and the adjusting component presses the emergency on - off component 50 to turn on the main on - off component 40 and the emergency on - off component 50; the locking component 60 is used to maintain the position of the operating mechanism 20 relative to the switch body 30; the emergency button 23 is used to release the pressing on the emergency on - off component 50 through the adjusting component.

[0037] It is connected in series to the heating circuit through the main on-off component 40 and the emergency on-off component 50. When the user presses the operating mechanism 20 towards the switch body 30, the lifting seat 21 presses the main on-off component 40 and the adjusting component presses the emergency on-off component 50, causing the interiors of the main on-off component 40 and the emergency on-off component 50 to be connected. The circuit where the heating component of the toaster is located forms a path, and the food in the toaster starts to be heated. The locking component 60 maintains the positional relationship between the operating mechanism 20 and the switch body 30 during normal heating. After the food heating is completed, the locking component 60 releases the locking of the operating mechanism 20, and then the reset traction member drives the lifting seat 21 to move away from the switch body 30, causing the main on-off component 40 and the emergency on-off component 50 to be released to the off state and stopping the heating of the toaster. When the operating mechanism 20 is blocked and cannot move and reset away from the switch body 30, by operating the emergency button 23, the abutting effect between the adjusting component and the emergency on-off component 50 is released, causing the emergency on-off component 50 to be released and internally disconnected, cutting off the current of the heating component of the toaster. Since the emergency on-off component 50 is integrated in the switch body 30, the cable connection relationship inside the toaster can be simplified, and at the same time, the assembly efficiency of the toaster can be improved.

[0038] Specifically, the lifting seat 21 is movably sleeved on the sliding rod and moves under the guiding action of the sliding rod. After the locking component 60 releases the locking of the lifting seat 21, the reset traction member moves the lifting seat 21 in the direction away from the switch body 30 to release the pressing on the main on-off component 40 and the emergency on-off component 50, cutting off the current of the heating component. Specifically, the reset traction member is a tension spring.

[0039] Furthermore, since the emergency on-off component 50 is integrated in the switch body 30 and the emergency button 23 is arranged on the lifting seat 21, when a conventional toaster without the function of forced power-off needs to add the forced power-off function, only the switch body 30 and the operating mechanism 20 need to be replaced, and there is no need to make excessive adjustments to the circuit layout or the housing of the toaster.

[0040] Please refer to Figure 2 and Figure 3 , in one of the implementation manners, the switch body 30 further includes a housing 70, a main button 80 movably passing through the housing 70, and a sub-button 90 movably passing through the housing 70; the main on-off component 40 and the emergency on-off component 50 are accommodated in the housing 70; the lifting seat 21 presses the main on-off component 40 through the main button 80; the adjusting component presses the emergency on-off component 50 through the sub-button 90.

[0041] By accommodating the main on-off component 40 and the emergency on-off component 50 in a housing 70 made of insulating material, it can effectively prevent the metal parts of the main on-off component 40 or the emergency on-off component 50 from leaking electricity. The operating mechanism 20 acts on the parts of the main button 80 or the sub-button 90 made of insulating material that are exposed outside the housing 70, so that there is no need to directly contact the main on-off component 40 or the emergency on-off component 50, improving the electrical safety.

[0042] Furthermore, to improve the structural stability of the switch body 30, the locking component 60 is accommodated in the housing 70; in other embodiments, the main on-off component 40 and the emergency on-off component 50 can also be accommodated in a closed space formed by the toaster housing.

[0043] Please refer to Figure 2 , in one of the embodiments, the lifting seat 21 is provided with a fixed pressing part 211, and the fixed pressing part 211 is used to press the main button 80; the adjusting component includes a rotating part 221 pivotally connected to the lifting seat 21 and a first elastic part 224 connected to the rotating part 221. The first elastic part 224 enables the rotating part 221 to maintain a predetermined angle relative to the lifting seat 21 through the emergency button; the emergency button 23 is connected to the rotating part 221; the rotating part 221 is provided with a movable pressing part 222 for pressing the sub-button 90.

[0044] When the lifting seat 21 moves closer to the switch body 30, since the first elastic part 224 keeps the angle of the rotating part 221 relative to the lifting seat 21 fixed, the fixed pressing part 211 and the movable pressing part 222 respectively press the main button 80 and the sub-button 90, and through mechanical action, the main on-off component 40 and the emergency on-off component 50 are switched to the on state. When the lifting seat 21 cannot move due to being blocked by food, the movement of the emergency button 23 drives the rotating part 221 to deflect relative to the lifting seat 21. When the angle of the rotating part 221 is adjusted, the movable pressing part 222 leaves the sub-button 90, releasing the pressing on the emergency on-off component 50, and allowing the emergency on-off component 50 to return to the off state, cutting off the circuit of the heating component.

[0045] Please refer to Figure 2 , in one of the embodiments, the emergency button 23 is located on the side of the fixed handle 212 closer to the switch body 30; the first elastic part 224 abuts between the fixed handle 212 and the emergency button 23. By pushing the fixed handle 212 in the direction closer to the switch body 30, the lifting seat 21 and the adjusting component can be driven to move; since the emergency button 23 is located on the side of the fixed handle 212 closer to the switch body 30, it can prevent the accidental triggering of the emergency button 23 when operating the fixed handle 212.

[0046] Since the first elastic member 224 can automatically reset the turning member 221 to a predetermined angle, and the reset of the turning member 221 drives the reset of the emergency button 23. When the jammed food in the toaster is removed, the reset traction member drives the lifting seat 21 to reset to a position away from the switch body 30. At the same time, the emergency button 23 and the turning member 221 are reset under the action of the first elastic member 224. When it is necessary to connect the heating circuit next time, only the fixed handle 212 needs to be pushed, and no other adjustments to the emergency button 23 or the adjustment component are required, thus simplifying the operation of the switch.

[0047] Specifically, the first elastic member 224 is a compression spring and is accommodated in the fixed handle 212 and the emergency button 23; to further reduce the accidental triggering of the emergency button 23, a part of the emergency button 23 is accommodated in the fixed handle 212. The turning member 221 is provided with a positioning block 223, and the first elastic member 224 pushes the turning member 221 until the positioning block 223 abuts against the lifting seat 21, so as to keep the angle between the turning member 221 and the lifting seat 21 stable.

[0048] Please refer to Figure 8 , in one of the embodiments, the lifting seat 21 is provided with a fixed pressing portion 211 for pressing the main button 80; the adjustment component includes a sliding member 225 slidably connected to the lifting seat 21 and a second elastic member 226 abutting against the sliding member 225, and the second elastic member 226 is used to keep the sliding member 225 in a predetermined position relative to the lifting seat 21; the emergency button 23 abuts against the sliding member 225; the sliding member 225 is provided with a movable pressing portion 222 for pressing the sub-button 90.

[0049] When the lifting seat 21 moves closer to the switch body 30, since the second elastic member 226 keeps the sliding member 225 in a predetermined position relative to the lifting seat 21, the fixed pressing portion 211 and the movable pressing portion 222 respectively press the main button 80 and the sub-button 90, and through mechanical action, the main on-off component 40 and the emergency on-off component 50 are switched to the on state. When the lifting seat 21 cannot move due to the jamming of food, the movement of the emergency button 23 drives the sliding member 225 to move relative to the lifting seat 21 and the sub-button 90. When the position of the sliding member 225 changes, the movable pressing portion 222 leaves the sub-button 90, releasing the pressing on the emergency on-off component 50, and allowing the emergency on-off component 50 to return to the off state, cutting off the circuit of the heating component.

[0050] Since the second elastic member 226 can automatically reset the sliding member 225 to a predetermined position, the reset of the sliding member 225 drives the reset of the emergency button 23. When the jammed food in the toaster is removed, the reset traction member drives the lifting seat 21 to reset to a position away from the switch body 30. At the same time, the emergency button 23 and the sliding member 225 are reset under the action of the second elastic member 226. When it is necessary to connect the heating circuit next time, only the fixed handle 212 needs to be pushed, and no other adjustments need to be made to the emergency button 23 or the adjustment component, thus simplifying the operation of the switch.

[0051] Please refer to Figure 8 , in one of the embodiments, one of the lifting seat 21 and the sliding member 225 has a sliding groove 213, and the other has a sliding block 227; the sliding block 227 is movably received in the sliding groove 213; the second elastic member 226 abuts between the lifting seat 21 and the sliding member 225. Since the emergency button 23 moves with the sliding member 225 and the emergency button 23 movably passes 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 accidentally triggering the emergency button 23 when operating the fixed handle 212. The extending direction of the sliding groove 213 is perpendicular to the moving direction of the lifting seat 21, so as to minimize the resistance when pushing the emergency button 23 or the sliding member 225.

[0052] The lifting seat 21 is provided with a fixed pressing portion 211 for pressing the main button 80; the adjustment component is provided with a movable pressing portion 222 for pressing the sub-button 90; before the operating mechanism 20 contacts the switch 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.

[0053] When it is necessary to connect the circuit where the heating component is located, as the lifting seat 21 moves closer to the switch body 30, the movable pressing portion 222 contacts the sub-button 90 earlier than the fixed pressing portion 211 contacts the main button 80; when it is necessary to cut off the circuit where the heating component is located, as the lifting seat 21 moves away from the switch body 30, the movable pressing portion 222 leaves the sub-button 90 later than the fixed pressing portion 211 leaves the main button 80, so as to avoid the emergency on-off component 50 being directly used to cut off the current, prevent the generation of electric arcs in the emergency on-off component 50, maintain the good breaking ability of the emergency on-off component 50, and reliably cut off the current of the heating component in an emergency.

[0054] Please refer to Figure 5 and Figure 6, in one embodiment, the main on-off component 40 includes a first side-foot conductive sheet 41 connected to the housing 70, a middle-foot conductive sheet 42 connected to the housing 70, and a first moving contact piece 43 movably disposed in the housing 70; the first moving contact piece 43 enables the first side-foot conductive sheet 41 and the middle-foot conductive sheet 42 to switch between electrical connection and electrical isolation through movement, and the movement of the first moving contact piece 43 is driven by the main button 80; the emergency on-off component 50 includes a second side-foot conductive sheet 51 connected to the housing 70 and a second moving contact piece 52 movably disposed in the housing 70; the second moving contact piece 52 enables the second side-foot conductive sheet 51 and the middle-foot conductive sheet 42 to switch between electrical connection and electrical isolation through movement, and the movement of the second moving contact piece 52 is driven by the sub-button 90.

[0055] When it is necessary to connect the circuit where the heating component is located, the first side-foot conductive sheet 41, the first moving contact piece 43, the middle-foot conductive sheet 42, the second moving contact piece 52, and the second side-foot conductive sheet 51 are sequentially contacted and connected in series in the circuit between the heating component and the power supply to allow current to pass through the heating component. When it is necessary to cut off the circuit where the heating component is located, the lifting seat 21 moves away from the switch body 30, and the main button 80 drives the first moving contact piece 43 away from the first side-foot conductive sheet 41 or the middle-foot conductive sheet 42. At the same time or afterwards, the sub-button 90 drives the second moving contact piece 52 away from the second side-foot conductive sheet 51 or the middle-foot conductive sheet 42 to generate electrical isolation.

[0056] Specifically, the first side-foot conductive sheet 41, the middle-foot conductive sheet 42, the first moving contact piece 43, the second side-foot conductive sheet 51, and the second moving contact piece 52 are made of metal or alloy. Preferably, they are made of copper.

[0057] Please refer to Figure 5 and Figure 6 , in one embodiment, the first moving contact piece 43 and the first side-foot conductive sheet 41, or the first moving contact piece 43 and the middle-foot conductive sheet 42 are in contact through the contact points; the second moving contact piece 52 and the middle-foot conductive sheet 42, or the second moving contact piece 52 and the second side-foot conductive sheet 51 are in contact through the contact points. Thereby, the conductive ability of the main on-off component 40 and the emergency on-off component 50 is improved and the oxidation rate is reduced.

[0058] Please refer to Figure 3 and Figure 4 , in one embodiment, the first moving contact piece 43 and the second moving contact piece 52 remain in contact with the middle-foot conductive sheet 42 during the movement process. Therefore, the connection or disconnection of the main on-off component 40 is determined by the distance between the first side-foot conductive sheet 41 and the first moving contact piece 43, and the connection or disconnection of the emergency on-off component 50 is determined by the gap between the second side-foot conductive sheet 51 and the second moving contact piece 52, thereby simplifying the structure of the switch body 30.

[0059] Please refer to Figure 5 andFigure 6 In one embodiment, the main button 80 has a first side extension 81 with an inclined surface thereon; the switch body 30 further includes a first abutting elastic member 82 for pressing the first moving contact piece 43 against the first side extension 81; the inclined surface on the first side extension 81 is used to guide the first moving contact piece 43 to abut against the middle-foot conductive piece 42; the sub-button 90 has a second side extension 91 with an inclined surface thereon; the switch body 30 further includes a second abutting elastic member 92 for pressing the second moving contact piece 52 against the second side extension 91; the inclined surface on the second side extension 91 is used to guide the second moving contact piece 52 to abut against the middle-foot conductive piece 42.

[0060] By adjusting the direction of the inclined surface such that the side closer to the middle-foot conductive piece 42 is lower, the first side extension 81 and the second side extension 91 respectively guide the angles of the first moving contact piece 43 and the second moving contact piece 52. Before the pressing of the operating mechanism 20 is received, the first moving contact piece 43 and the second moving contact piece 52 can respectively abut against the middle-foot conductive piece 42, thereby simplifying the installation of the first moving contact piece 43 and the second moving contact piece 52. Additionally, since the first moving contact piece 43 and the second moving contact piece 52 are separately connected to the middle-foot conductive piece 42 and can maintain contact with the middle-foot conductive piece 42 at the same time, there is no need to consider the problem of ensuring the elastic movement range, and the thickness of the first moving contact piece 43 and the second moving contact piece 52 can be increased. For example, a metal sheet with a thickness of 0.8 mm or more can be used to increase the maximum allowable passing current of the main on-off assembly 40 or the emergency on-off assembly 50.

[0061] Please refer to Figure 5 In one embodiment, a first locking particle extends from the side of the first moving contact piece 43 facing away from the first side extension 81, and one end of the first abutting elastic member 82 abuts against the first locking particle; a second locking particle 53 extends from the side of the second moving contact piece 52 facing away from the second side extension 91, and one end of the second abutting elastic member 92 abuts against the second locking particle 53. The first abutting elastic member 82 is a compression spring, and its two ends respectively abut against the main button 80 and the first locking particle, so that the first moving contact piece 43 can actively slide along the inclined surface towards the middle-foot conductive member. The second abutting elastic member 92 is a compression spring, and its two ends respectively abut against the sub-button 90 and the second locking particle 53, so that the second moving contact piece 52 can actively slide along the inclined surface towards the middle-foot conductive member.

[0062] Please refer to Figure 5 and Figure 6, in one of the embodiments, the main button 80 further has a first side hook portion 83 connecting to the first side extension portion 81, and the first movable contact piece 43 is received between the first side hook portion 83 and the main body of the main button 80; the secondary button 90 further has a second side hook portion 93 connecting to the second side extension portion 91, and the second movable contact piece 52 is received between the second side hook portion 93 and the main body of the secondary button 90. Thereby, it can be avoided that the first movable contact piece 43 comes off from the main button 80 or the second movable contact piece 52 comes off from the secondary button 90.

[0063] Please refer to Figure 5 , in one of the embodiments, the middle leg conductive piece 42 is provided with an arc-shaped groove 421; the first movable contact piece 43 or the second movable contact piece 52 has a V-shaped portion 431, and the convex side of the V-shaped portion 431 is attached to the surface of the arc-shaped groove 421; the rib feature of the housing 70 extends into the concave side of the V-shaped portion 431. Through the contact and cooperation between the arc-shaped groove 421 and the V-shaped portion 431, the first movable contact piece 43 or the second movable contact piece 52 can maintain sufficient contact with the middle leg conductive piece 42 during the movement process, reducing the resistance; the rib feature of the housing 70 extending into the concave side of the V-shaped portion 431 can limit the movement range of the first movable contact piece 43 or the second movable contact piece 52, and can facilitate the assembly of the switch body 30, avoiding the need to pivotally connect the first movable contact piece 43 or the second movable contact piece 52 to the middle leg conductive member.

[0064] Please refer to Figure 6 , in one of the embodiments, the main on-off component 40 includes a third side leg conductive member 45 connecting to the housing 70, a fourth side leg conductive member 46 connecting to the housing 70, and a third movable contact piece 47 movably arranged in the housing 70; the third movable contact piece 47 switches between electrical connection and electrical isolation of the third side leg conductive piece and the fourth side leg conductive member 46 through movement, and the movement of the third movable contact piece 47 is driven by the main button 80. One end of the heating component is connected to the phase wire of the power supply through the first side leg conductive piece 41 and the second side leg conductive piece 51, and the other end is connected to the neutral wire of the power supply through the third side leg conductive member 45 and the fourth side leg conductive member 46, thereby ensuring that the heating component can be reliably isolated from the power supply in the power-off state.

[0065] Further, the movement ranges of the first movable contact piece 43, the second movable contact piece 52, and the third movable contact piece 47 are arranged parallel to each other, making the first movable contact piece 43, the second movable contact piece 52, and the third movable contact piece 47 side by side with each other, thereby reducing the volume of the switch body.

[0066] Please refer to Figure 3 and Figure 5, in one embodiment, the switch body 30 further includes a third elastic member 72, and the third elastic member 72 is configured to move the main button 80 or the secondary button 90 along the reset direction of the operating mechanism 20. After the lifting seat 21 and the adjusting assembly release the pressing on the main button 80 or the secondary button 90, the elastic force of the third elastic member 72 pushes the main button 80 or the secondary button 90 in the reverse direction, driving the first moving contact piece 43 away from the first side-foot conductive piece 41 or the second moving contact piece 52 away from the second side-foot conductive piece 51, so that the main on-off assembly 40 and the emergency on-off assembly 50 can promptly resume the open state.

[0067] Please refer to Figure 3 , in one embodiment, a positioning pin 71 extends inside the housing 70, and the positioning pin 71 passes through the main button 80 or the secondary button 90; the third elastic member 72 is sleeved on the positioning pin 71. By passing the positioning pin 71 through the main button 80 or the secondary button 90, the moving direction of the main button 80 or the secondary button 90 can be restricted, preventing dislocation.

[0068] Please refer to Figure 2 , in one embodiment, the lifting seat 21 has a hook portion 214; the locking assembly 60 includes an electromagnetic member 61 connected to the housing 70 and an armature member 62 movably connected to the housing 70; the electromagnetic member 61 is configured to attract the armature member 62 to lock the position or angle of the armature member 62; the armature member 62 has a hook portion 621, and the hook portion 621 cooperates with the hook portion 214 to lock the lifting seat 21 in a position close to the switch body 30. Thus, by controlling the magnetic force of the electromagnetic member 61, the position of the armature member 62 can be locked. After the position of the armature member 62 is locked, the hook portion 621 abuts against the hook portion 214, preventing the lifting seat 21 from being driven by the reset traction member to reset, and maintaining the pressing of the operating mechanism 20 on the main button 80 and the secondary button 90.

[0069] Please refer to Figure 2 , the side cross-sections of the hook portion 214 and the hook portion 621 are respectively V-shaped. Thus, the weights of the hook portion 214 and the hook portion 621 can be reduced, and by adjusting the extending angles of the hook portion 214 and the hook portion 621, for example, reducing the angle between the inclined surface of the hook portion 621 facing the hook portion 214 relative to the moving direction of the hook portion 214, the resistance when the hook portion 214 is buckled onto the hook portion 621 can be reduced. Specifically, before the electromagnetic member 61 generates magnetic force, when the lifting seat 21 moves close to the switch body 30, the hook portion 214 abuts against the hook portion 621, then the armature member 62 deflects, and at the same time, the hook portion 621 swings away from the electromagnetic member 61. After the hook portion 214 moves in place, the hook portion 621 abuts against the concave side of the hook portion 214, and at the same time, the electromagnetic member 61 generates magnetic force, locking the position or direction of the armature member 62 and locking the positions of the hook portion 214 and the lifting seat 21.

[0070] The first abutting surface is provided on the hook receiving portion 214, and the second abutting surface is provided on the hook portion 621 of the armature. The first abutting surface and the second abutting surface are arranged in parallel or nearly parallel; when the lifting seat 21 is locked at a position close to the switch body 30, the first abutting surface and the second abutting surface are in contact with each other; the axial direction of the sliding rod is perpendicular or nearly perpendicular to the first abutting surface or the second abutting surface. By using the component force in the axial direction of the sliding rod when the first abutting surface and the second abutting surface are in contact, the suction force required for the electromagnetic member 61 to lock the lifting seat 21 can be reduced.

[0071] Please refer to Figure 4 and Figure 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 portion 621 of the armature 62 in a direction close to the armature 62. The fourth elastic member 63 enables the armature 62 to actively abut against the electromagnetic member 61, avoiding the inability to attract and fix the armature 62 due to an excessive gap between the armature 62 and the electromagnetic member 61.

[0072] Specifically, a deflection fulcrum 73 extends inside the housing 70, and the deflection fulcrum 73 is located on the side of the armature 62 facing away from the electromagnet; the fourth elastic member 63 is a compression spring and its two ends respectively abut against the armature 62 and the inner wall of the housing 70. The abutting portion of the armature 62 and the fourth elastic member 63 is on one side of the deflection fulcrum 73, and the hook portion 621 is on the other side of the deflection fulcrum 73. Under the lever action, the fourth elastic member 63 drives the armature 62 to deflect, and the hook portion 621 moves in a direction close to the armature 62.

[0073] In this embodiment, when the operating mechanism 20 is blocked and cannot move and reset away from the switch body 30, by operating the emergency button 23, the abutting effect between the adjusting assembly and the emergency on-off assembly 50 is released, so that the emergency on-off assembly 50 is released and internally disconnected, cutting off the current of the heating component of the toaster. Since the emergency on-off assembly 50 is integrated in the switch body 30, the cable connection relationship inside the toaster can be simplified, and at the same time, the assembly efficiency of the toaster can be improved.

[0074] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0075] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
