[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0033] like Figures 1 to 6 As shown, an embodiment of the utility model provides a housing, which includes a housing 10 and a pressure plate 30. The housing 10 has a chip placement groove 11 and a wire outlet 141 connected to the chip placement groove 11, and the chip unit 20 is arranged in the chip placement groove 11. The pressure plate 30 is detachably connected to the housing 10, and the pressure plate 30 has an initial position away from the chip placement groove 11 and an assembly position covering the chip placement groove 11 and the wire outlet 141.

[0034] When the detection member provided by this embodiment is used and the detection member is assembled, the chip unit 20 is first placed in the chip placement groove 11 of the housing 10 when the pressing plate 30 is in the initial position, and the lead 22 of the chip unit 20 is passed through the outlet 141, and then the pressing plate 30 is moved from the initial position to the assembly position. At this time, the chip unit 20 can be fixed in the housing 10 by the pressing plate 30 to complete the assembly of the detection member. With the above assembly method, there is no need to fill the detection member with glue, which can simplify the manufacturing process and reduce costs.

[0035] In this embodiment, the first end of the pressure plate 30 is hinged to the shell 10, and the second end of the pressure plate 30 is detachably connected to the shell 10. The outlet 141 is arranged at a position of the shell 10 corresponding to the second end of the pressure plate 30, which has the advantages of simple assembly structure and easy assembly.

[0036] It should be noted that one end of the pressure plate 30 is hinged to the shell 10, including the following two structures: the first is that one end of the pressure plate 30 is hinged to the shell 10 by a rotating shaft connection, and the second is that the pressure plate 30 is hinged to the shell 10 by an integral molding method.

[0037] In this embodiment, the pressing plate 30 and the housing 10 are an integrally formed structure, which has the advantages of being easy to process and having low processing costs.

[0038] The thickness of the portion where the pressing plate 30 is connected to the shell 10 is between 0.3 mm and 1 mm, so that the pressing plate 30 can be hinged to the shell 10 through the portion where the pressing plate 30 is connected to the shell 10 .

[0039] The thickness of the portion where the pressing plate 30 is connected to the shell 10 is set between 0.3 mm and 1 mm, which can not only ensure the connection strength between the pressing plate 30 and the shell 10 , but also facilitate the flipping of the pressing plate 30 relative to the shell 10 .

[0040] Specifically, the thickness of the portion where the pressing plate 30 is connected to the housing 10 can be 0.3 mm, 0.5 mm, 0.7 mm, 0.9 mm, 1 mm, or any other value between 0.3 mm and 1 mm.

[0041] like Figure 2 and Figure 4 As shown, the first end of the pressing plate 30 is hinged to the housing 10, and a clamping structure 40 is provided between the second end of the pressing plate 30 and the housing 10. When the pressing plate 30 is turned over to the assembly position, the clamping structure 40 can be used to fix the pressing plate 30 and the housing 10.

[0042] The clamping structure 40 includes a first clamping boss 41 and a second clamping boss 42 for clamping cooperation. The first clamping boss 41 is provided on the side wall of the chip placement groove 11, and the second clamping boss 42 is provided on the end wall of the pressure plate 30. The clamping cooperation between the first clamping boss 41 and the second clamping boss 42 is used to fix the pressure plate 30 and the housing 10, which has the advantages of simple structure and easy processing.

[0043] like Figure 1 As shown, the chip unit 20 includes a chip 21 and two leads 22 electrically connected to the chip 21, a lead separation rib 12 is provided in the chip placement groove 11, the lead separation rib 12 extends along the extension direction of the chip placement groove 11 and is located between the two leads 22, and a first clamping boss 41 is provided on the side wall of the lead separation rib 12. The lead separation rib 12 can prevent the two leads 22 from contacting and short-circuiting.

[0044] In this embodiment, the diameter of the lead 22 is larger than the distance between the first clamping boss 41 on the side wall of the chip placement groove 11 and the first clamping boss 41 on the side wall of the lead separation rib 12. The first clamping boss 41 can be used to limit the lead 22 to prevent the lead 22 from falling out, thereby improving the assembly firmness.

[0045] like Figure 4 As shown, the side wall of the second clamping boss 42 has a guide slope 421 corresponding to the first clamping boss 41, and the lower end of the second clamping boss 42 is provided with a transition fillet 422. In the process of clamping the second clamping boss 42 to the bottom of the first clamping boss 41, the guide slope 421 and the transition fillet 422 can be used for assembly guidance to facilitate assembly.

[0046] like Figures 1 to 4 As shown, the housing 10 includes a first bottom plate 13 and a first enclosure 14 arranged around the outer periphery of the first bottom plate 13, the lower end of the first enclosure 14 is connected to the edge of the first bottom plate 13, the upper surface of the first bottom plate 13 and the inner side wall of the first enclosure 14 together form a chip placement groove 11, and the pressing plate 30 is hinged to the first enclosure 14. The chip placement groove 11 is formed by the first bottom plate 13 and the first enclosure 14, so that the structure of the housing 10 is simple, which can further reduce the cost.

[0047] Among them, the first base plate 13 includes a first plate segment 131 and a second plate segment 132 that are perpendicular to each other, one end of the first plate segment 131 is connected to one end of the second plate segment 132, and the first enclosure 14 is provided with an outlet 141 at the end of the second plate segment 132 away from the first plate segment 131, and the leads 22 of the chip unit 20 can pass through the outlet 141.

By providing the anti-idiot groove 17, it is convenient to observe the front and back sides of the detection member during the process of assembling the detection member to the cooking utensil, which can play an anti-idiot role.

[0049] Furthermore, a fool-proofing protrusion corresponding to the fool-proofing groove 17 may be provided on the cooking utensil, so that the detection element can be assembled on the cooking utensil only when the fool-proofing protrusion is inserted into the fool-proofing groove 17, thereby further improving the fool-proofing effect.

[0050] In other embodiments, the second bottom plate 15 may not be provided, and the housing 10 may be provided to further include a second enclosure 16, the second enclosure 16 being located on the side of the second plate segment 132 away from the first plate segment 131, the outer side wall of the first enclosure 14 and the inner side wall of the second enclosure 16 together enclose a foolproof hole, and the foolproof hole is used to play a foolproof role. Alternatively, the second bottom plate 15 and the second enclosure 16 enclosed on the outer periphery of the second bottom plate 15 may not be provided at the same time, and in this case the housing 10 is an L-shaped structure, which can also play a foolproof role.

[0051] In this embodiment, the shape of the pressing plate 30 is adapted to the shape of the chip placement groove 11. When the pressing plate 30 is located at the assembly position, the upper surface of the pressing plate 30 is flush with the upper surface of the first enclosure 14, which can improve the surface flatness of the detection component.
