[0002] The thermal cut-off device can cut off the circuit when the temperature is high, so as to play the role of a protective device. For example, a thermal cut-off device can be provided on the cooking cavity of a cooking appliance. When the temperature of the cooking cavity is too high, the thermal cut-off device can cut off the circuit, so as to play the role of protecting the cooking cavity.
[0003] The applicant has developed a thermal cut-off device, comprising a main body and a first terminal and a second terminal connected to the main body, wherein the first terminal and the second terminal are both bent, and the directions of the bent portions of the two are the same, which can effectively increase the creepage distance. However, the thermal cut-off device is usually used in conjunction with a sheath, and the universal size of the thermal cut-off device is larger than the spacing between the two interfaces of the universal sheath, resulting in the need to customize the sheath, thereby increasing the use cost of the thermal cut-off device. Utility Model Content
[0004] In view of this, the utility model provides a thermal cut-off device, a circuit protection component and a cooking appliance to solve the problem that the size of the thermal cut-off device in the related art does not match that of a universal sheath, resulting in the need to customize the sheath and increasing the use cost of the thermal cut-off device.
[0005] In a first aspect, the utility model provides a thermal cut-off device, comprising:
[0006] main body;
[0007] A first terminal connected to the main body;
[0008] A second terminal connected to the main body and located on one side of the first terminal, the first terminal and the second terminal are both bent, and the extension direction of the plug-in ends of the first terminal and the second terminal is the same;
[0009] A first extension section is formed on the first terminal, and the first extension section extends in a direction close to the second terminal; and / or a second extension section is formed on the second terminal, and the second extension section extends in a direction close to the first terminal.
[0010] Beneficial effect: The plug-in ends of the first terminal and the second terminal of the thermal cutoff of the utility model are constructed to extend in the same direction, so that when the thermal cutoff is installed on the cooking cavity, the first terminal and the second terminal can both extend in a direction away from the cooking cavity, thereby away from the metal conductor near the thermal cutoff, thereby effectively increasing the creepage distance to solve the problem of creepage risk after the thermal cutoff is installed on the cooking cavity in the prior art, thereby improving the safety of the cooking appliance.
[0011] On this basis, the first extension section and the second extension section can reduce the distance between the plug-in ends of the first terminal and the second terminal, thereby allowing the distance between the fixing points of the first terminal and the second terminal of the thermal cut-off device to be set according to the universal size of the thermal cut-off device, avoiding the need to develop a new mold, and at the same time, the distance between the plug-in ends of the first terminal and the second terminal can match the size of a universal sheath (that is, the distance between the plug-in ends of the first terminal and the second terminal is compatible with the distance between the two interfaces of the universal sheath, and can be plugged with the universal sheath), so that the universal sheath can be compatible with the thermal cut-off device of this embodiment, thereby reducing the use cost of the thermal cut-off device.

The second plug-in section extends radially along the columnar base. The second connecting section is connected between the second extension section and the second plug-in section.
[0015] Beneficial effects:
[0016] By so configuring, the first extension section and the second extension section are covered on the end surface of the columnar base, which can be used to connect the first terminal and the second terminal to the columnar base, and can also play a role in reducing the distance between the plug-in ends of the first terminal and the second terminal. The plug-in end of the first terminal is formed on the first plug-in section, and the plug-in end of the second terminal is formed on the second plug-in section.

[0018] Beneficial effects:
[0019] When D1 meets the above range, the distance between the first mounting point and the second mounting point meets the universal size of the thermal cut-off device, and there is no need to develop a new mold, thereby avoiding increasing the manufacturing cost of the thermal cut-off device. When D2 meets the above range, the first plug-in section and the second plug-in section can be plugged into a universal sheath, meeting the maximum universal rule.
[0020] In an optional embodiment, the first terminal further includes a first inclined section, the first connecting section is connected to an end of the first extension section close to the second terminal and extends along the axial direction of the columnar base, the first inclined section is connected between the first connecting section and the first plug-in section, and in a direction away from the first connecting section, the first inclined section is inclined in a direction away from the second terminal; and / or,

In the direction away from the second connecting section, the second inclined section is inclined in the direction away from the first terminal.

[0059] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0060] Combine the following Figures 1 to 3 , describing an embodiment of the utility model.
[0061] According to an embodiment of the utility model, on the one hand, a thermal cut-off device is provided, comprising a main body 1, a first terminal 2 and a second terminal 3. The first terminal 2 is connected to the main body 1. The second terminal 3 is connected to the main body 1 and is located on one side of the first terminal 2. The first terminal 2 and the second terminal 3 are both bent, and the extension direction of the plug-in ends of the first terminal 2 and the second terminal 3 is the same. A first extension section 201 is formed on the first terminal 2, and the first extension section 201 extends in a direction close to the second terminal 3; and / or a second extension section 301 is formed on the second terminal 3, and the second extension section 301 extends in a direction close to the first terminal 2.
[0062] The plug-in ends of the first terminal 2 and the second terminal 3 of the thermal cutoff of the utility model are constructed to extend in the same direction, so that when the thermal cutoff is installed on the cooking cavity, the first terminal 2 and the second terminal 3 can both extend in a direction away from the cooking cavity, thereby away from the metal conductor near the thermal cutoff, thereby effectively increasing the creepage distance to solve the problem of creepage risk after the thermal cutoff is installed on the cooking cavity in the prior art, thereby improving the safety of the cooking appliance.
[0063] On this basis, the first extension section 201 and the second extension section 301 can reduce the distance between the plug-in ends of the first terminal 2 and the second terminal 3, thereby allowing the distance between the fixing points of the first terminal 2 and the second terminal 3 of the thermal cut-off device to be set according to the universal size of the thermal cut-off device, avoiding the need to develop a new mold, and at the same time, the distance between the plug-in ends of the first terminal 2 and the second terminal 3 can match the size of the universal sheath 5 (that is, the distance between the plug-in ends of the first terminal 2 and the second terminal 3 is compatible with the distance between the two interfaces of the universal sheath 5, and can be plugged with the universal sheath 5), so that the universal sheath 5 can be compatible with the thermal cut-off device of this embodiment, so as to reduce the use cost of the thermal cut-off device.
[0064] In addition, the thermal cut-off device of the utility model has a simple structure, is easy to assemble, is safe and reliable to use, and is easy to implement, popularize and apply.
[0065] As an optional embodiment, a fuse part may be provided in the main body 1, and both ends of the fuse part are respectively connected to the first terminal 2 and the second terminal 3, which can conduct the first terminal 2 and the second terminal 3 and fuse at a predetermined temperature, thereby cutting off the circuit.
[0066] In one embodiment, the main body 1 includes a columnar base, the first terminal 2 also includes a first plug-in section 202 and a first connecting section 203, the first extension section 201 is connected to the end surface of the columnar base, the first plug-in section 202 extends along the radial direction of the columnar base, and the first connecting section 203 is connected between the first extension section 201 and the first plug-in section 202;
[0067] The second terminal 3 further includes a second plug-in section 302 and a second connecting section 303 . The second extension section 301 is connected to the end surface of the columnar base. The second plug-in section 302 extends radially along the columnar base. The second connecting section 303 is connected between the second extension section 301 and the second plug-in section 302 .
[0068] By such arrangement, the first extension section 201 and the second extension section 301 are covered on the end surface of the columnar base, which can be used to connect the first terminal 2 and the second terminal 3 to the columnar base, and can also play a role in reducing the distance between the plug-in ends of the first terminal 2 and the second terminal 3. The plug-in end of the first terminal 2 is formed on the first plug-in section 202, and the plug-in end of the second terminal 3 is formed on the second plug-in section 302.
[0069] The extending directions of the first connecting section 203 and the first extending section 201 may be selected to be perpendicular to each other. As a changeable implementation, the extending directions of the first connecting section 203 and the first extending section 201 may be selected to form an acute angle or an obtuse angle.
[0070] The extension directions of the second connecting section 303 and the second extending section 301 may be selected to be perpendicular to each other. As a convertible implementation, the extension directions of the second connecting section 303 and the second extending section 301 may be selected to form an acute angle or an obtuse angle.
[0071] As a convertible implementation, the first extension section 201 is directly inserted on the end face of the columnar base and then extends toward the second terminal 3 , and the second extension section 301 is directly inserted on the end face of the columnar base and then extends toward the first terminal 2 .
[0072] As an alternative embodiment, the main body 1 may also include a prismatic base or a special-shaped base.
[0073] In one embodiment, the first extension section 201 is installed on the columnar base through the first mounting point 102, and the second extension section 301 is installed on the columnar base through the second mounting point 103. The distance between the first mounting point 102 and the second mounting point 103 is defined as D1, 7.8mm≤D1≤8.2mm, and the distance between the first plug-in section 202 and the second plug-in section 302 is defined as D2, 5.8mm≤D2≤6.2mm.
[0074] When D1 meets the above range, the distance between the first mounting point 102 and the second mounting point 103 meets the universal size of the thermal cut-off device, and there is no need to develop a new mold, thereby avoiding increasing the manufacturing cost of the thermal cut-off device. When D2 meets the above range, the first plug-in section 202 and the second plug-in section 302 can be plugged into the universal sheath 5, which meets the maximum universal rule.
[0075] In one embodiment, the first terminal 2 also includes a first inclined section 204, the first connecting section 203 is connected to an end of the first extension section 201 close to the second terminal 3, and extends along the axial direction of the columnar base, the first inclined section 204 is connected between the first connecting section 203 and the first plug-in section 202, and in the direction away from the first connecting section 203, the first inclined section 204 is inclined in the direction away from the second terminal 3.
[0076] The second terminal 3 also includes a second inclined section 304. The second connecting section 303 is connected to one end of the second extension section 301 close to the first terminal 2 and extends along the axial direction of the columnar base. The second inclined section 304 is connected between the second connecting section 303 and the second plug-in section 302. In the direction away from the second connecting section 303, the second inclined section 304 is inclined in the direction away from the first terminal 2.
[0077] Since the first extension section 201 needs to extend to the side of the first mounting point 102 close to the second terminal 3 and then connect to the first connecting section 203, the second extension section 301 needs to extend to the side of the second mounting point 103 close to the first terminal 2 and then connect to the second connecting section 303, through such a setting, the distance between the first connecting section 203 and the second connecting section 303 may be smaller than the size of the universal sheath 5. Therefore, the thermal cut-off device implemented in the present application is respectively provided with a first inclined section 204 and a second inclined section 304 on the first terminal 2 and the second terminal 3. The first inclined section 204 and the second inclined section 304 extend in directions away from each other, thereby increasing the distance between the first plug-in section 202 and the second plug-in section 302, and ensuring that the first plug-in section 202 and the second plug-in section 302 of the embodiment of the present application can be plugged into the universal sheath 5.
[0078] In one embodiment, the distance between the first connecting section 203 and the second connecting section 303 is defined as D3, 3mm≤D3≤4mm. When the distance between the first connecting section 203 and the second connecting section 303 is smaller than the above size, the thermal cut-off device does not meet the safety requirements. When the distance between the first connecting section 203 and the second connecting section 303 is larger than the above size, the distance between the first mounting point 102 and the second mounting point 103 may not meet the production requirements.
[0079] In one embodiment, the first terminal 2 and the second terminal 3 are both formed by bending an L-shaped metal sheet.
[0080] By such arrangement, it is ensured that the first terminal 2 and the second terminal 3 can be arranged in a central symmetrical manner on the sheet material, so as to reduce the scraps generated during the punching process, thereby saving the materials consumed in the preparation process of the first terminal 2 and the second terminal 3 and meeting the safety regulations. Figure 3 As shown, Figure 3 The diagram shows the arrangement of the first terminals 2 and the second terminals 3 on the sheet material during the manufacturing process.
[0081] In one embodiment, a receiving groove 101 is provided on the end surface of the columnar base, and the first terminal 2 and the second terminal 3 are connected in the receiving groove 101 .
[0082] By setting in this way, steps can be formed on both sides of the installation point of the first terminal 2 and the second terminal 3, so that the metal conductive part of the thermal cutout is not easy to contact the metal part outside, preventing contact with the live body, thereby playing the role of hiding the live part. In addition, when external force acts on this part, it can act on the step first, thereby playing a protective role.
[0083] In one embodiment, the first plug section 202 and the second plug section 302 are both provided with self-locking holes 4. The self-locking holes 4 can be locked and connected with the connecting wire when the thermal cut-off device is plugged into the terminal, so as to prevent the connecting wire from falling off.
[0084] According to an embodiment of the present utility model, on the other hand, a circuit protection component is also provided, such as Figure 4 As shown, it includes a thermal cut-off device and a sheath 5. The sheath 5 includes a sheath body, a first slot and a second slot are formed on one side of the sheath body, a third terminal and a fourth terminal are respectively arranged in the first slot and the second slot, the third terminal and the fourth terminal are respectively suitable for connecting with a connecting wire, and the connecting wire is led out from the sheath body, and the first terminal 2 and the second terminal 3 are respectively suitable for being inserted in the first slot and the second slot and connected with the connecting wire.
[0085] The sheath 5 of this embodiment is provided with a first slot and a second slot respectively suitable for plugging with the first terminal 2 and the second terminal 3 on the same sheath body. The operator only needs to put the sheath 5 on the thermal cut-off device to simultaneously complete the connection between the first terminal 2 and the third terminal, and the connection between the second terminal 3 and the fourth terminal. Thus, the plugging process is completed in one step, which can reduce the operator's labor intensity, improve the plugging efficiency, and help reduce the phenomenon of wrong plugging and missed plugging.
[0086] In addition, the circuit protection component of the utility model includes or uses the thermal cut-off device of the first aspect of the utility model, and thus can achieve its beneficial effect, namely: the first terminal 2 and the second terminal 3 of the thermal cut-off device can both extend in a direction away from the cooking cavity of the cooking device, thereby away from the metal conductor near the thermal cut-off device, thereby effectively increasing the creepage distance and improving the safety of the cooking appliance.
[0087] The distance between the fixing points of the first terminal 2 and the second terminal 3 of the thermal cut-off device can be set according to the universal size of the thermal cut-off device, avoiding the need to develop a new mold. At the same time, the distance between the plug-in ends of the first terminal 2 and the second terminal 3 can match the size of the universal sheath 5 (that is, the distance between the plug-in ends of the first terminal 2 and the second terminal 3 is adapted to the distance between the two interfaces of the universal sheath 5 and can be plugged into the universal sheath 5), so that the universal sheath 5 can be adapted to the thermal cut-off device of this embodiment, thereby reducing the use cost of the thermal cut-off device.
[0088] In one embodiment, the circuit protection assembly further includes a circuit board 7 and a light emitting element 8 , wherein the circuit board 7 is electrically connected to the third terminal via a first connection line 601 , and the fourth terminal is electrically connected to the fourth terminal via a second connection line 602 .

The third terminal is preferably connected to the filter board, that is, the input end of the main circuit. The light emitting element 8 is preferably, but not limited to, an incandescent lamp or an LED lamp.

[0091] The cooking appliance of the third aspect of the utility model includes or uses the circuit protection assembly provided by the second aspect of the utility model, and thus has its beneficial effects, namely:
[0092] The first terminal 2 and the second terminal 3 of the thermal cut-off can both extend in a direction away from the cooking cavity of the cooking device, thereby away from the metal conductor near the thermal cut-off, thereby effectively increasing the creepage distance and improving the safety of the cooking appliance.
[0093] The distance between the fixing points of the first terminal 2 and the second terminal 3 of the thermal cut-off device can be set according to the universal size of the thermal cut-off device, avoiding the need to develop a new mold. At the same time, the distance between the plug-in ends of the first terminal 2 and the second terminal 3 can match the size of the universal sheath 5 (that is, the distance between the plug-in ends of the first terminal 2 and the second terminal 3 is adapted to the distance between the two interfaces of the universal sheath 5 and can be plugged into the universal sheath 5), so that the universal sheath 5 can be adapted to the thermal cut-off device of this embodiment, thereby reducing the use cost of the thermal cut-off device.
