Description

Technical Field

[0001] The present application relates to the technical field of temperature measuring instruments, and in particular to a food temperature probe and a food temperature detection assembly. Background Art

[0002] Barbecue is a dish with a unique flavor that is widely loved by people. However, since the meat needs to be cooked at the right temperature, it requires high skills and experience from the griller. In order to reduce the difficulty of barbecue, barbecues are usually equipped with food temperature probes to monitor the internal temperature of the barbecue or the temperature of the environment in which it is grilled.

[0003] Generally, a food temperature probe includes a housing, a handle, and a temperature measuring element. The temperature measuring element is disposed in a cavity formed by the housing and the handle. The user inserts the housing into the food by holding the handle. The temperature measuring element is used to detect the temperature of the food environment and generate a corresponding temperature signal. In the related art, sealing glue is usually used to achieve relative fixation between the position of the handle and the housing, and to achieve a waterproof seal at the connection point between the handle and the housing. However, since the food temperature probe needs to withstand high temperatures for a long time, the commonly used silicone sealing glue is easily carbonized in a high-temperature environment, resulting in the failure of the adhesive and waterproof properties of the sealing glue.

[0026] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0027] In a first aspect, the present application proposes a food temperature probe, which is resistant to high temperatures and has good waterproof and sealing properties.

[0028] The food temperature probe includes a housing, a handle, a connector, a press-fit member, and a temperature measurement assembly. The housing has a first accommodating cavity. The handle has a second accommodating cavity. The first end of the connector extends into the first accommodating cavity of the housing, and the second end of the connector extends into the second accommodating cavity of the handle. The press-fit member is disposed around the periphery of the first end of the connector and the periphery of the second end of the connector, and is used to seal the housing, handle, and connector together. The temperature measurement assembly is at least partially disposed in the first accommodating cavity of the housing or the second accommodating cavity of the handle.

[0029] In the food temperature probe according to the embodiment of the present application, the housing and the first end of the connector are joined together by a press-fit piece, forming a sealed connection point at the end of the housing on the side where the opening of the first accommodating cavity is located, thereby effectively limiting the entry of liquid into the first accommodating cavity of the housing from the assembly gap between the housing and the first end of the connector, thereby ensuring that the food temperature probe has excellent waterproof sealing performance while being resistant to high temperatures. The handle and the second end of the connector are sealed together by a press-fit piece, forming a sealed connection point at the end of the handle on the side where the opening of the second accommodating cavity is located, thereby effectively limiting the entry of liquid into the second accommodating cavity of the handle from the assembly gap between the handle and the second end of the connector, thereby ensuring that the food temperature probe has excellent waterproof sealing performance while being resistant to high temperatures.

[0030] The specific structure of the food temperature probe 1 is described below in conjunction with the accompanying drawings.

[0031] like Figure 1-Figure 3 As shown, the food temperature probe 1 includes a housing 10, a handle 20, a connector 30, a press-fitting member 40, and a temperature measuring assembly. The connector 30 and the press-fitting member 40 are used to seal the housing 10 and the handle 20 together, and the temperature measuring assembly is disposed inside the housing 10 and / or the handle 20.

[0032] Specifically, the housing 10 serves as a shell of the food temperature probe 1 and is used to be inserted into the food (such as barbecue). The material of the housing 10 can be, but is not limited to, metal materials such as stainless steel or aluminum alloy.

[0033] The housing 10 has a first accommodating cavity 10a. The housing 10 is a long tubular structure with an open end and a closed tip at the other end (the internal hollow area of ​​the housing 10 is the first accommodating cavity 10a). This configuration allows the food temperature probe 1 to be better inserted into food to measure the temperature when in use.

[0034] The handle 20 serves as another housing of the food temperature probe 1 and is used for the user to hold so that the user can insert the food temperature probe 1 into the food and remove the food temperature probe 1 from the food. The material of the handle 20 can be, but is not limited to, metal materials such as stainless steel or aluminum alloy.

[0035] The handle 20 has a second accommodating cavity 20a. The handle 20 is a long tubular structure with one end open and the other end closed (the internal hollow area of ​​the handle 20 includes the second accommodating cavity 20a). This arrangement makes it easy for the user to insert the food temperature probe 1 into food and remove the food temperature probe 1 from the food with the help of the handle 20.

[0036] The connecting member 30 can serve as an intermediate connecting structure between the housing 10 and the handle 20 .

[0037] Specifically, the first end of the connector 30 extends into the first accommodating cavity 10a of the housing 10, and the second end of the connector 30 extends into the second accommodating cavity 20a of the handle 20. The first end and the second end of the connector 30 are arranged along the length direction of the food temperature probe 1.

[0038] The press-fitting part 40 serves as a sealing part of the food temperature probe 1. On the one hand, the press-fitting part 40 is sleeved around the periphery of the first end of the connector 30 to seal the assembly gap between the first end of the connector 30 and the housing 10. On the other hand, the press-fitting part 40 is also sleeved around the periphery of the second end of the connector 30 to seal the assembly gap between the second end of the connector 30 and the handle 20.

[0039] Specifically, the press-fit member 40 is used to seal the housing 10, the handle 20, and the connector 30 together, so as to restrict liquid from entering the first accommodating chamber 10a of the housing 10 through the assembly gap between the housing 10 and the first end of the connector 30, and to restrict liquid from entering the second accommodating chamber 20a of the handle 20 through the assembly gap between the handle 20 and the second end of the connector 30. For example, the housing 10 can be connected to the first end of the connector 30 by threaded fastening, and the handle 20 can be connected to the second end of the connector 30 by threaded fastening. In this case, the press-fit member 40 may include an elastic sealing ring or an elastic sealing tube. When the housing 10 is threadedly connected to the first end of the connector 30, the elastic sealing ring or elastic sealing tube is compressed, filling the assembly gap between the housing 10 and the first end of the connector 30, thereby achieving a sealing effect. When the handle 20 is threadedly connected to the second end of the connector 30, the elastic sealing ring or elastic sealing tube is compressed, filling the assembly gap between the handle 20 and the second end of the connector 30, thereby achieving a sealing effect.

[0040] The temperature measuring component is used to measure the temperature inside the food on the one hand, and to measure the temperature of the environment in which the food is located on the other hand. At least part of the temperature measuring component can be arranged in the first accommodating cavity 10a of the housing 10, but it is not limited to the above. In other modified embodiments, the temperature measuring component can also be arranged in the second accommodating cavity 20a of the handle 20, or extend from the first accommodating cavity 10a of the housing 10 to the second accommodating cavity 20a of the handle 20. Based on the food temperature probe 1 in the embodiment of the present application, the housing 10 and the first end of the connector 30 are sealed together by the press-fit component 40, and a sealed connection point can be formed at the end of the side where the cavity opening of the first accommodating cavity 10a of the housing 10 is located, so as to effectively limit the liquid from entering the first accommodating cavity 10a of the housing 10 from the assembly gap between the housing 10 and the first end of the connector 30, so that the food temperature probe 1 has good waterproof performance while being resistant to high temperatures. The handle 20 and the second end of the connector 30 are sealed together by a press-fit piece 40, and a sealed connection point can be formed at the end of the side where the opening of the second accommodating cavity 20a of the handle 20 is located, so as to effectively limit the liquid from entering the second accommodating cavity 20a of the handle 20 from the assembly gap between the handle 20 and the second end of the connector 30, so that the food temperature probe 1 has good waterproof performance while being resistant to high temperatures.

[0041] It can be understood that in some embodiments, the press-fitting member 40 is adapted to deform under force to interference fit with the inner side surfaces of the housing 10 and the handle 20 , thereby sealingly connecting the housing 10 , the handle 20 and the connector 30 together.

[0042] There is no limitation on the specific material of the pressing part 40. Designers can make reasonable choices based on actual needs. As long as the material can be deformed under force and has high temperature resistance, it can be used. For example, the material of the pressing part 40 can be but is not limited to nano-ceramics, metal or stainless steel.

[0043] It should be noted that the pressing piece 40 has a tubular structure, and the cylindrical pressing piece 40 will produce a slight deformation during the process of being subjected to force; the slight deformation causes the pressing piece 40 to have an interference fit with the inner side surface of the shell 10, and can form a sealed connection point at the end of the side where the cavity opening of the first accommodating cavity 10a of the shell 10 is located, so that the shell 10 and the first end of the connector 30 are sealed together through the pressing piece 40, so as to effectively limit the liquid from entering the first accommodating cavity 10a of the shell 10 from the assembly gap between the shell 10 and the first end of the connector 30; the slight deformation also causes the pressing piece 40 to have an interference fit with the inner side surface of the handle 20, and can form a sealed connection point at the end of the side where the cavity opening of the second accommodating cavity 20a of the handle 20 is located, so that the handle 20 and the second end of the connector 30 are sealed together through the pressing piece 40, so as to effectively limit the liquid from entering the second accommodating cavity 20a of the handle 20 from the assembly gap between the handle 20 and the second end of the connector 30.

[0044] like Figure 1-Figure 3 As shown, the material design of the housing 10, the handle 20, the connecting member 30 and the pressing member 40 can include, but is not limited to, one or more of the following embodiments. The following are just some examples.

[0045] In the first embodiment, the housing 10 is made of stainless steel. Stainless steel has good thermal conductivity, allowing the food temperature probe 1 to effectively measure food temperature. It also has good electrical conductivity, allowing the housing 10 to serve as a first charging electrode, effectively charging the food temperature probe 1.

[0046] In the second embodiment, the handle 20 is made of stainless steel. By designing the handle 20 to be made of stainless steel, stainless steel is suitable for use as an antenna that, together with the signal transmission element 52, can form the antenna of the food temperature probe 1 to transmit antenna signals to or receive antenna signals from an external terminal. Stainless steel has good electrical conductivity, allowing the handle 20 to function as a second charging electrode, effectively charging the food temperature probe 1.

[0047] In the third embodiment, the connecting member 30 is made of ceramic. Ceramic has good thermal insulation properties, which prevents heat from being transferred from the housing 10 to the handle 20. This makes it easier for the user to insert the food temperature probe 1 into food and remove it from food using the handle 20.

[0048] In the fourth embodiment, the pressing member 40 is made of copper. By designing the pressing member 40 to be made of copper, copper has good ductility, so that the pressing member 40 can be deformed under force to be sealed together with the housing 10, the handle 20 and the connecting member 30 through an interference fit.

[0049] See also Figure 3-Figure 5 The press-fitting part 40 includes a sleeve 41 and a barrier portion 42. The sleeve 41 is sleeved around the periphery of the first end of the connector 30 and is also sleeved around the periphery of the second end of the connector 30. The barrier portion 42 is provided on the outer side of the sleeve 41. After the press-fitting part 40 is assembled, the barrier portion 42 is tightly combined with the inner side of the housing 10 and the inner side of the handle 20 by the friction force generated by the interference fit. The barrier portion 42 is used to form a sealed path to prevent liquid from entering the first accommodating cavity 10a of the housing 10 and the second accommodating cavity 20a of the handle 20. The barrier portion 42 can be a solid structure such as a ridge provided on the outer side of the sleeve 41, or a virtual structure such as a groove formed on the outer side of the sleeve 41. By designing a barrier portion 42 on the outer surface of the sleeve 41, the barrier portion 42 forms a sealed path that blocks liquid from entering the first accommodating cavity 10a of the housing 10 and the second accommodating cavity 20a of the handle 20. This reduces the difficulty of liquid entering the first accommodating cavity 10a of the housing 10 and the second accommodating cavity 20a of the handle 20 through the assembly gap, further enhancing the waterproof performance of the food temperature probe 1. It is worth noting that when the barrier portion 42 is a solid structure such as a ridge disposed on the outer surface of the sleeve 41, the compression member 40 deforms under force, creating a partial interference fit between the barrier portion 42 and the inner surface of the housing 10, and also between the barrier portion 42 and the inner surface of the handle 20.

[0050] When the barrier portion 42 is a physical structure such as a ridge disposed on the outer side of the sleeve 41, the barrier portion 42 includes at least one annular sealing strip 421 disposed on the outer side of the sleeve 41, each annular sealing strip 421 being disposed around the axis of the sleeve 41. When there is only one annular sealing strip 421, a side area of ​​the annular sealing strip 421 near the opening of the first accommodating chamber 10a is used to form the aforementioned sealing path. In this case, the side area of ​​the annular sealing strip 421 near the opening of the first accommodating chamber 10a is used to accommodate a small amount of liquid that enters through the assembly gap, thereby preventing the liquid from directly entering the first accommodating chamber 10a of the housing 10 and the second accommodating chamber 20a of the handle 20. This reduces the difficulty of liquid entering the first accommodating chamber 10a of the housing 10 and the second accommodating chamber 20a of the handle 20 through the assembly gap, thereby further improving the waterproof performance of the food temperature probe 1. When there are multiple annular sealing strips 421, the multiple annular sealing strips 421 are arranged at intervals along the axis of the sleeve 41, and the interval between two adjacent annular sealing strips 421 is used to form the above-mentioned sealing path; at this time, the interval between two adjacent annular sealing strips 421 can be used to accommodate a small amount of liquid entering from the assembly gap, so that the liquid entering from the assembly gap will not directly enter the first accommodating chamber 10a of the shell 10 and the second accommodating chamber 20a of the handle 20, thereby increasing the difficulty of liquid entering the first accommodating chamber 10a of the shell 10 and the second accommodating chamber 20a of the handle 20 from the assembly gap, thereby further improving the waterproof performance of the food temperature probe 1. Among them, the annular sealing strip 421 can be an annular convex strip or another annular sealing ring; when the annular sealing strip 421 is an annular convex strip, the annular convex strip can be, but is not limited to, a detachable fixed connection with the sleeve 41 by at least one of screw connection, clip connection or plug-in connection, and the annular convex strip can also be, but is not limited to, a non-detachable fixed connection with the sleeve 41 by riveting, injection molding or 3D printing; when the annular sealing strip 421 is another annular sealing ring, the other annular sealing ring is sleeved on the periphery of the sleeve 41 and has an interference fit with the outer surface of the sleeve 41.

[0051] When the barrier portion 42 is a virtual structure, such as a groove, formed on the outer surface of the sleeve 41, the barrier portion 42 may include at least one annular groove 422 disposed on the outer surface of the sleeve 41. Each annular groove 422 is disposed around the axis of the sleeve 41 and serves to form the aforementioned sealing path. When there are multiple annular grooves 422, the plurality of annular grooves 422 are spaced apart along the axis of the sleeve 41. By designing at least one annular groove 422 on the outer surface of the sleeve 41, the annular grooves 422 can be used to accommodate a small amount of liquid that enters through the assembly gap, preventing the liquid from directly entering the first accommodating chamber 10a of the housing 10 and the second accommodating chamber 20a of the handle 20. This reduces the difficulty of liquid entering the first accommodating chamber 10a of the housing 10 and the second accommodating chamber 20a of the handle 20 from the assembly gap, thereby further enhancing the waterproof performance of the food temperature probe 1.

[0052] like Figure 3-Figure 5 As shown, the housing 10 has a first cross-section perpendicular to the longitudinal axis of the sleeve 41, and the inner contour of the first cross-section is circular; the handle 20 has a second cross-section perpendicular to the longitudinal axis of the sleeve 41, and the inner contour of the second cross-section is circular; the connector 30 has a third cross-section perpendicular to the longitudinal axis of the sleeve 41, and the outer contour of the third cross-section is circular; the sleeve 41 has a fourth cross-section perpendicular to its longitudinal axis, and the fourth cross-section includes an inner annular line and an outer annular line, the inner annular line is circular, and the outer annular line is circular. Among them, the outer surface of the connector 30 can be processed by external cylindrical grinding to achieve very high precision and cylindricity of the outer surface of the connector 30, and the sleeve 41 can be processed by lathing to achieve high precision and cylindricity, which is consistent with the precision and cylindricity of the connector 30. In this way, after the sleeve 41 and the connector 30 are sealed, the assembly gap between the inner surface of the sleeve 41 and the outer surface of the connector 30 is small, thereby achieving good waterproofing. By designing the inner contour of the first cross-section of the housing 10 to be circular, and the outer annular line of the fourth cross-section of the sleeve 41 to be circular, the assembly gap between the inner side surface of the housing 10 and the outer side surface of the sleeve 41 is reduced after the housing 10 and the sleeve 41 are sealed together, thereby achieving a good waterproofing effect. By designing the inner contour of the second cross-section of the handle 20 to be circular, and the outer annular line of the fourth cross-section of the sleeve 41 to be circular, the assembly gap between the inner side surface of the handle 20 and the outer side surface of the sleeve 41 is reduced after the handle 20 and the sleeve 41 are sealed together, thereby achieving a good waterproofing effect. By designing the outer contour of the third cross-section of the connector 30 to be circular, and the inner annular line of the fourth cross-section of the sleeve 41 to be circular, the assembly gap between the inner side surface of the sleeve 41 and the outer side surface of the connector 30 is reduced after the sleeve 41 and the connector 30 are sealed together, thereby achieving a good waterproofing effect.

[0053] Specifically, other structural designs of the sleeve 41 , the housing 10 and the handle 20 may include, but are not limited to, one or more of the following embodiments.

[0054] In the first embodiment, the thickness of the sleeve 41 is greater than or equal to 0.1 mm and less than or equal to 1 mm. For example, the thickness of the sleeve 41 can be, but is not limited to, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, or 1 mm. By rationally designing the thickness of the sleeve 41, the sleeve 41 expands outward and deforms when subjected to force, thereby reducing the assembly gap between the outer surface of the sleeve 41 and the inner surface of the housing 10, as well as reducing the assembly gap between the outer surface of the sleeve 41 and the inner surface of the handle 20, thereby further improving the waterproof performance of the food temperature probe 1. It will be understood that, based on the above thickness range, the greater the thickness of the sleeve 41, the better the waterproof performance and the stronger the connection stability of the sleeve 41, the connector 30, and the handle 20 formed by the interference fit.

[0055] In the second embodiment, the thickness of the outer shell 10 is greater than or equal to 0.05 mm and less than or equal to 0.3 mm. For example, the thickness of the outer shell 10 may be, but is not limited to, 0.05 mm, 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, or 0.3 mm. By rationally designing the thickness of the outer shell 10 so that it is neither too thin nor too thick, the outer shell 10 expands outward and deforms slightly when subjected to force, thereby ensuring a good seal between the outer shell 10 and the sleeve 41 and preventing the outer shell 10 from squeezing and damaging the barrier 42 disposed on the outer side of the sleeve 41.

[0056] In the third embodiment, the thickness of the portion of the handle 20 corresponding to the second accommodating cavity 20a gradually increases from the side closest to the opening of the second accommodating cavity 20a to the side further away from the opening of the second accommodating cavity 20a. By designing the end of the handle 20 near the opening of the second accommodating cavity 20a to have a thin-walled structure, the end of the handle 20 near the opening of the second accommodating cavity 20a expands outward and deforms slightly when subjected to force. This ensures a good seal between the handle 20 and the sleeve 41 and prevents the handle 20 from squeezing and damaging the barrier 42 provided on the outer side of the sleeve 41.

[0057] like Figure 3-Figure 5As shown, the connecting member 30 includes a connecting portion 31 and a stopping portion 32; the connecting portion 31 extends along the axis OO in the length direction D of the pressing member 40 (specifically the above-mentioned sleeve 41); the stopping portion 32 is arranged on the periphery of the connecting portion 31 to divide the connecting portion 31 into a first connecting segment 311 and a second connecting segment 312, the first connecting segment 311 serving as the first end of the connecting member 30 extending into the first accommodating cavity 10a of the housing 10, and the second connecting segment 312 serving as the second end of the connecting member 30 extending into the second accommodating cavity 20a of the handle 20.

[0058] The press-fitting element 40 (specifically, the aforementioned sleeve 41) includes a first sleeve 411 and a second sleeve 412. The first sleeve 411 is sleeved around the first connecting section 311, while the second sleeve 412 is sleeved around the second connecting section 312. The stopper 32 is used to limit the movement of the first sleeve 411 and the second sleeve 412 toward each other until they abut against each other.

[0059] Among them, the stopping portion 32 can be, but is not limited to, a detachable fixed connection with the connecting portion 31 by at least one of screw connection, clip connection or plug-in connection; the stopping portion 32 can also be, but is not limited to, a non-detachable fixed connection with the connecting portion 31 by riveting, injection molding or 3D printing.

[0060] By designing a stop portion 32 on the periphery of the connecting portion 31, the stop portion 32 divides the connecting portion 31 into a first connecting segment 311 and a second connecting segment 312. The first connecting segment 311 serves as the first end of the connecting member 30 for the first sleeve 411 to be mounted, and the second connecting segment 312 serves as the second end of the connecting member 30 for the second sleeve 412 to be mounted. The design of the stop portion 32 can achieve an assembly stop between the first sleeve 411 and the first connecting segment 311, thereby facilitating the assembly between the housing 10, the first sleeve 411 and the first connecting segment 311. The design of the stop portion 32 can also achieve an assembly stop between the second sleeve 412 and the second connecting segment 312, thereby facilitating the assembly between the handle 20, the second sleeve 412 and the second connecting segment 312.

[0061] The housing 10 has a first surface 10b facing the handle 20, with a first accommodating cavity 10a extending inwardly from the first surface 10b of the housing 10. The handle 20 has a second surface 20b facing the housing 10, with the second accommodating cavity 20a extending inwardly from the second surface 20b of the handle 20. The retaining portion 32 includes a retaining ring 321 disposed on the periphery of the connecting portion 31. When the housing 10, handle 20, connecting member 30, and press-fitting member 40 are sealed together, one end surface of the retaining ring 321 abuts against the first surface 10b of the housing 10, and the other end surface of the retaining ring 321 abuts against the second surface 20b of the handle 20.

[0062] Among them, the stopping ring 321 can be, but is not limited to, a detachable fixed connection with the connecting part 31 by at least one of screw connection, clip connection or plug-in connection, and the stopping ring 321 can also be, but is not limited to, a non-detachable fixed connection with the connecting part 31 by riveting, injection molding or 3D printing.

[0063] When the shell 10, the handle 20, the connector 30 and the press-fitting part 40 are sealed together, by allowing one end face of the stop ring 321 to fit against the first surface 10b of the shell 10 and the other end face of the stop ring 321 to fit against the second surface 20b of the handle 20, the stop ring 321 can achieve an assembly stop position between the shell 10 and the first connecting section 311, thereby facilitating the assembly between the shell 10, the first sleeve 411 and the first connecting section 311. Similarly, the stop ring 321 can also achieve an assembly stop position between the handle 20 and the second connecting section 312, thereby facilitating the assembly between the handle 20, the second sleeve 412 and the second connecting section 312. By designing the stopping portion 32 as a stopping ring 321, one end face of the stopping ring 321 is in contact with the first surface 10b of the outer shell 10, thereby achieving a circumferential seal between the stopping ring 321 and the outer shell 10, thereby further improving the waterproof performance of the food temperature probe 1. Similarly, the other end face of the stopping ring 321 is in contact with the second surface 20b of the handle 20, thereby achieving a circumferential seal between the stopping ring 321 and the handle 20, thereby further improving the waterproof performance of the food temperature probe 1.

[0064] like Figure 5 In the embodiment shown, the stopper 32 is a stopper ring 321. However, please refer to Figure 6 In other embodiments, the stopper portion 32 may also be at least one stopper protrusion. Specifically, the stopper portion 32 may include a plurality of stopper protrusions 322 spaced apart around the axis OO of the sleeve 41 and arranged on the periphery of the connecting portion 31. In this case, the first surface 10b of the housing 10 protrudes toward the handle 20 to form a plurality of spaced apart first sealing protrusions 11, and the second surface 20b of the handle 20 protrudes toward the housing 10 to form a plurality of spaced apart second sealing protrusions 21. The first sealing protrusions 11 and the second sealing protrusions 21 are used to seal the spaces 323 between adjacent stopper protrusions 322.

[0065] The following combination Figure 5 、 7 and Figure 8 The principle of preventing a small amount of liquid from entering the accommodating cavity of the handle 20 through the assembly gap and then entering the first accommodating cavity 10a of the housing 10 in the embodiment of the present application is described.

[0066] like Figure 5 and Figure 7As shown, when a small amount of liquid may enter from the assembly gap, a part of the liquid will enter the gap between the outer side of the first sleeve 411 and the inner side of the shell 10. At this time, due to the design of the barrier portion 42, the barrier portion 42 can effectively prevent the liquid from further entering the first accommodating cavity 10a of the shell 10 from the gap between the outer side of the first sleeve 411 and the inner side of the shell 10. When a small amount of liquid enters from the assembly gap, another part of the liquid will enter the gap between the inner side of the first sleeve 411 and the outer side of the first connecting section 311. At this time, in order to effectively prevent the liquid from further entering the first accommodating cavity 10a of the shell 10 from the gap between the inner side of the first sleeve 411 and the outer side of the first connecting section 311. Therefore, the design is as follows. Figure 5 and Figure 8 As shown, the first connecting section 311 includes a first portion 3111 and a second portion 3112 connected to the first portion 3111. The first portion 3111 is farther from the second connecting section 312 than the second portion 3112. The first sleeve 411 is sleeved around the outer periphery of the second portion 3112. The connecting member 30 also includes a snap-fit ​​portion 33 disposed on the first portion 3111. The food temperature probe 1 also includes a first sealing member 60 disposed on the snap-fit ​​portion 33 to seal the gap between the first portion 3111 and the inner side surface of the housing 10.

[0067] The engaging portion 33 may be a physical structure such as a engaging protrusion provided on the first portion 3111 , or a virtual structure such as a engaging groove formed on the first portion 3111 .

[0068] The first sealing member 60 is used to seal the gap between the first portion 3111 and the inner side of the housing 10 to prevent liquid from further entering the first receiving cavity 10a of the housing 10. The first sealing member 60 can be, but is not limited to, a sealing ring or a sealing adhesive layer 71.

[0069] By designing the first seal 60, the first seal 60 is used to seal the gap between the first part 3111 and the inner side of the outer shell 10. At this time, the first seal 60 can not only effectively prevent the liquid from further entering the first accommodating cavity 10a of the outer shell 10 from the gap between the inner side of the first sleeve 411 and the outer side of the second part 3112, but also prevent the liquid from further entering the first accommodating cavity 10a of the outer shell 10 from the gap between the outer side of the first sleeve 411 and the inner side of the outer shell 10. In this way, the waterproof performance of the food temperature probe 1 can be further improved.

[0070] Specifically, if Figure 5 and Figure 8As shown, the engaging portion 33 includes an annular groove 331 disposed on the periphery of the first portion 3111. The annular groove 331 is disposed around the axis of the sleeve 41. The first sealing member 60 includes an annular sealing ring 61, which is embedded in the annular groove 331 and has an interference fit with the inner side surface of the housing 10 to seal the gap between the first portion 3111 and the inner side surface of the housing 10. By designing the clamping portion 33 as an annular clamping groove 331 and designing the first sealing component 60 as an annular sealing ring 61, the annular sealing ring 61 is embedded in the annular clamping groove 331 to achieve relative fixation of the position between the annular sealing ring 61 and the first part 3111, and the annular sealing ring 61 is interference fit with the inner side surface of the outer shell 10 to seal the gap between the first part 3111 and the inner side surface of the outer shell 10. At this time, the annular sealing ring 61 can not only effectively prevent the liquid from further entering the first accommodating chamber 10a of the outer shell 10 from the gap between the inner side surface of the first sleeve 411 and the outer side surface of the second part 3112, but the annular sealing ring 61 can also prevent the liquid from further entering the first accommodating chamber 10a of the outer shell 10 from the gap between the outer side surface of the first sleeve 411 and the inner side surface of the outer shell 10, thereby further improving the waterproof performance of the food temperature probe 1.

[0071] See also Figure 2 、 Figure 3 and Figure 9 The temperature measuring component is used to measure temperature and generate a corresponding temperature sensing signal, and includes a temperature measuring body 51. Specifically, the temperature measuring body 51 is used to measure the temperature of the environment in which the food is located. The temperature measuring body 51 is in the shape of an elongated strip extending along the length direction of the food temperature probe 1. The food temperature probe 1 also includes a signal transmission element 52, which is used to transmit, emit and / or receive antenna signals. The signal transmission element 52 has a cavity 52a for accommodating the temperature measuring body 51. The food temperature probe 1 also includes a circuit board 81, which is electrically connected to the temperature measuring body 51 and the signal transmission element 52. The handle 20 also has a third accommodating cavity 20c, which extends from the bottom wall of the second accommodating cavity 20a away from the cavity opening of the second accommodating cavity 20a. The connector 30 is a tubular structure. The signal transmission element 52 is wrapped around the periphery of the temperature measuring body 51 to form a combination, which passes through the cylindrical cavity of the connector 30 and extends into the third accommodating cavity 20c of the handle 20. Of course, the temperature measurement assembly may also include a temperature sensing element 96 electrically connected to the circuit board 81. The temperature sensing element 96 may be positioned adjacent to the tip of the food temperature probe 1 to measure the internal temperature of the food. It will be appreciated that the temperature sensing signal generated by the temperature measurement assembly may include the temperature sensing signal acquired by the temperature measurement body 51 and the temperature signal acquired by the temperature sensing element 96.

[0072] It is understood that the specific forms of the temperature sensing signal generated by the temperature measuring body 51 may vary depending on the form of the temperature measuring body 51. For example, when the temperature measuring body 51 is a thermistor, the temperature sensing signal generated by the thermistor is a resistance signal. For another example, when the temperature measuring body 51 is a digital sensor, the temperature sensing signal generated by the digital sensor is a digitally encoded signal. For another example, when the temperature measuring body 51 is a thermocouple 511, the temperature sensing signal generated by the thermocouple 511 is a voltage signal. In the embodiment of the present application, the temperature measuring body 51 is a thermocouple 511.

[0073] The signal transmission element 52 is adapted to transmit, emit, and / or receive antenna signals. In one embodiment, the signal transmission element 52 can function independently as the antenna for the food temperature probe 1, or it can be electrically connected to another conductive medium and thereby function together with the other conductive medium as the antenna for the food temperature probe 1, thereby transmitting, emitting, and / or receiving antenna signals. Transmitting refers to wirelessly sending antenna signals, and receiving refers to wirelessly receiving other antenna signals sent by an external terminal. Antenna signals may include, but are not limited to, radio frequency signals.

[0074] Of course, if Figure 2 and Figure 3 As shown, the food temperature probe 1 may further include an elastic connector 94, which is used to secure the signal transmission element 52 to the handle 20. When the signal transmission element 52 is assembled to the elastic connector 94, the elastic connector 94 is adapted to deform to generate an elastic restoring force in the radial direction of the signal transmission element 52 to secure the signal transmission element 52. This effectively secures the signal transmission element 52, preventing the signal transmission element 52, which serves as an antenna, from loosening, allowing the signal transmission element 52 to effectively transmit the antenna signal, thereby ensuring the stability of the antenna signal transmission of the food temperature probe 1. The specific structure of the elastic connector 94 will not be described in detail here; designers can make reasonable designs based on actual needs.

[0075] When the elastic connector 94 is a conductive material, if the handle 20 is a conductive material such as stainless steel, the signal transmission element 52 is electrically connected to the handle 20 via the elastic connector 94, and the portion of the signal transmission element 52 located inside the handle 20, the elastic connector 94 and the handle 20 constitute the antenna of the food temperature probe 1. If the handle 20 is a non-conductive material such as ceramic, the signal transmission element 52 is electrically connected to the elastic connector 94, and the portion of the signal transmission element 52 located inside the handle 20 and the elastic connector 94 constitute the antenna of the food temperature probe 1.

[0076] When the elastic connecting member 94 is made of a non-conductive material, if the handle 20 is made of a non-conductive material such as ceramic, the antenna of the food temperature probe 1 can be composed only of the portion of the signal transmission element 52 located inside the handle 20. If the handle 20 is made of a conductive material such as stainless steel, the antenna of the food temperature probe 1 can be composed of the portion of the signal transmission element 52 located inside the handle 20 and the handle 20 (the signal transmission element 52 is directly electrically connected to the handle 20).

[0077] like Figure 10 and Figure 11 As shown, the temperature measuring body 51 can be spaced apart from the signal transmission element 52, that is, the temperature measuring body 51 does not contact the signal transmission element 52. The food temperature probe 1 can also include an insulating member 53. The insulating member 53 is used to prevent the temperature measuring body 51 from directly contacting the signal transmission element 52 and causing an electrical short circuit. On the other hand, the insulating member 53 is used to reduce the heat loss of the temperature measuring body 51 and maintain the thermal stability of the temperature measuring body 51. The insulating member 53 can include, but is not limited to, an insulating layer, an insulating gasket, or an insulating sleeve. The material of the insulating member 53 can include, but is not limited to, polyethylene, polyvinyl chloride, polytetrafluoroethylene, polyimide, natural rubber, styrene-butadiene rubber, silicone rubber, epoxy resin, phenolic resin, alumina ceramics, silica ceramics, quartz glass, borosilicate glass, natural mica, laminated mica layer, etc. The temperature measuring body 51 is connected to the signal transmission element 52 as a whole via an insulating member 53. The insulating member 53 serves as an intermediate connecting structure between the temperature measuring body 51 and the signal transmission element 52, and is used to connect the temperature measuring body 51 and the signal transmission element 52, thereby connecting the temperature measuring body 51 and the signal transmission element 52 as a whole. In this embodiment of the present application, the connection between the temperature measuring body 51 and the signal transmission element 52 is achieved by pouring an insulating slurry into the cavity 52a of the signal transmission element 52 and curing it to form an insulating layer.

[0078] like Figure 2 As shown, the housing 10 can be electrically connected to the electrical contact 81a on the circuit board 81, so that the housing 10 is suitable for use as a first charging electrode; the signal transmission element 52 is electrically connected to the handle 20, so that the handle 20 is suitable for use as a second charging electrode; one of the first charging electrode and the second charging electrode is a positive charging electrode, and the other of the first charging electrode and the second charging electrode is a negative charging electrode. In this way, the material of the housing 10 and the handle 20 is designed to be stainless steel, so that the housing 10 and the handle 20 form an effective charging circuit. In the embodiment of the present application, the housing 10 serves as the negative charging electrode and the handle 20 serves as the positive charging electrode. It should be noted that at this time, the housing 10 and the handle 20 are both made of conductive materials, and the housing 10 and the handle 20 are insulated and connected through the above-mentioned connector 30.

[0079] Of course, when both the housing 10 and the handle 20 are made of non-conductive materials, neither the housing 10 nor the handle 20 serves as a charging electrode. In this case, two charging pins are provided on the housing 10 and / or the handle 20, and the two charging pins serve as a first charging electrode and a second charging electrode and are electrically connected to the circuit board 81. When the housing 10 is made of a conductive material and the handle 20 is made of a non-conductive material, the housing 10 can serve as the first charging electrode, and the handle 20 can be provided with a single charging pin, which serves as the second charging electrode.

[0080] It is understandable that if Figure 12 and Figure 13 As shown, when a small amount of liquid may enter from the assembly gap, a part of the liquid will enter the gap between the outer side surface of the second sleeve 412 and the inner side surface of the handle 20. At this time, due to the design of the barrier portion 42, the barrier portion 42 can effectively prevent the liquid from further entering the second accommodating chamber 20a and the third accommodating chamber 20c of the handle 20 from the gap between the outer side surface of the second sleeve 412 and the inner side surface of the handle 20. When a small amount of liquid enters from the assembly gap, another part of the liquid will enter the gap between the inner side surface of the second sleeve 412 and the outer side surface of the second connecting section 312, and further enter the second accommodating chamber 20a and the third accommodating chamber 20c of the handle 20. At this time, in order to avoid direct contact between the liquid entering the third accommodating chamber 20c of the handle 20 and the temperature measuring body 51. Therefore, the design is as follows. Figure 9 As shown, the signal transmission element 52 includes a tube sidewall 521 and a tube end wall 522. The tube end wall 522 is sealedly connected to the end of the tube sidewall 521 near the handle 20 (specifically, the end of the tube sidewall 521 located within the third accommodating chamber 20c of the handle 20). The tube end wall 522 and the tube sidewall 521 together enclose a cavity 52a for accommodating the temperature measuring body 51. By designing the signal transmission element 52 to include the tube sidewall 521 and the tube end wall 522, the tube end wall 522 and the tube sidewall 521 enclose the cavity 52a for accommodating the temperature measuring body 51. This isolates the temperature measuring body 51 from direct contact with liquid entering the third accommodating chamber 20c of the handle 20, thereby effectively protecting the temperature measuring body 51. By designing the tube end wall 522 and the tube sidewall 521 to be sealed at the end, the waterproof sealing performance of the signal transmission element 52 with respect to the temperature measuring body 51 is further improved.

[0081] Specifically, a wireless communication chip (such as a Bluetooth chip) can be provided on the circuit board 81 to modulate the temperature sensing signal of the above-mentioned temperature measuring component into an antenna signal. When the signal transmission element 52, the elastic connector 94 and the handle 20 constitute the antenna of the food temperature probe 1, the antenna signal is transmitted to the elastic connector 94 via the signal transmission element 52, and then transmitted to the handle 20 by the elastic connector 94, and then emitted outward by the handle 20 to an external terminal (such as a mobile phone). The user can then understand the temperature of the food environment based on the relevant temperature data displayed on the external terminal.

[0082] It is understandable that if Figure 12-15 As shown, since the connecting member 30 is arranged in a tubular structure, when liquid enters the second accommodating cavity 20a and the third accommodating cavity 20c of the handle 20, the liquid will enter the gap between the inner side of the connecting member 30 and the outer side of the signal transmission element 52, and then enter the first accommodating cavity 10a of the housing 10. In order to prevent the liquid entering the second accommodating cavity 20a and the third accommodating cavity 20c of the handle 20 from reversely entering the first accommodating cavity 10a of the housing 10, it is designed as follows. Figure 8 As shown, the food temperature probe 1 further includes a second seal 70 , which is disposed at one end of the connector 30 away from the opening of the second accommodating cavity 20 a of the handle 20 , and is used to seal the gap between the signal transmission element 52 and the connector 30 .

[0083] Specifically, the second sealing member 70 includes a sealant layer 71, which is an annular structure disposed around the axis of the connector 30. The annular sealant layer 71 provides sealing properties to seal the gap between the signal transmission element 52 and the connector 30, effectively preventing liquid entering the second and third accommodating cavities 20a, 20c of the handle 20 from flowing back into the first accommodating cavity 10a of the housing 10. Furthermore, the annular sealant layer 71 provides adhesive properties to secure the relative position of the signal transmission element 52 and the connector 30, effectively reducing the difficulty of assembling the two elements. It should be noted that to extend the service life of the sealant layer 71, the selected colloid should be able to achieve tight and seamless adhesion on various materials, maintain good adhesion in various environments, adapt to minor deformation of various objects during use, and possess good high-temperature resistance. This configuration ensures that the food temperature probe 1 maintains a good sealing effect even in high-temperature operating environments.

[0084] Of course, in other embodiments, the second sealing member 70 may also be a sealing ring or a combination of a sealing ring and a sealing rubber layer 71. In this case, the sealing ring is used to seal the gap between the signal transmission element 52 and the connector 30. The signal transmission element 52 and the connector 30 may be relatively fixed by, but not limited to, screwing, snapping, plugging or bonding.

[0085] It is worth mentioning that in the present application, the housing 10, the handle 20, the connector 30 and the press-fitting part 40 are sealed together by a force interference fit to form a first seal, the first seal 60 is designed to form a second seal, and the second seal 70 is designed to form a third seal. The triple seals cooperate with each other, so that the food temperature probe 1 has excellent waterproof sealing performance while being resistant to high temperatures.

[0086] Second, as Figure 16 As shown, the present application proposes a food temperature detection assembly 1A. The food temperature detection assembly 1A can communicate with an external terminal 3, allowing a user to exchange information with the food temperature detection assembly 1A through the external terminal 3. The food temperature detection assembly 1A includes a storage device 2 and a food temperature probe 1 disposed in the storage device 2. The food temperature probe 1 adopts the food temperature probe 1 described in the above embodiment. Specifically, the storage device 2 has a storage slot 2a, and the food temperature probe 1 is detachably disposed in the storage slot 2a of the storage device 2.

[0087] The storage device 2 can be used to store the food temperature probe 1 when it is not in use. The storage device 2 can also be used to store and charge the food temperature probe 1. The specific structure of the food temperature probe 1 is similar to the above-mentioned embodiment. Since the food temperature detection assembly 1A adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be detailed here.

[0088] The storage device 2 can also serve as a relay station between the food temperature probe 1 and the external terminal 3. In this case, the food temperature probe 1 communicates with the external terminal 3 through the storage device 2. The handle 20, which serves as an antenna, can first send an antenna signal to the storage device 2, which then sends the antenna signal to the external terminal 3, so that the user can understand the temperature of the food environment based on the relevant temperature data displayed by the external terminal 3. Conversely, the external terminal 3 can also send an antenna signal to the storage device 2, which then sends the antenna signal to the food temperature probe 1, so that the food temperature probe 1 performs corresponding operations based on the antenna signal. As a relay station, the storage device 2 can process the received signal, eliminate some interference and noise, improve the clarity and integrity of the signal, and enable the external terminal 3 to more accurately receive the data sent by the food temperature probe 1. As a relay station, the storage device 2 can be placed in a relatively suitable position to avoid these interference sources and shielding objects, ensuring smooth signal transmission between the food temperature probe 1 and the external terminal 3. The storage device 2 acts as a relay station, and the food temperature probe 1 only needs to communicate with the storage device 2 at close range. Its design can be simplified, reducing costs and power consumption. It is also beneficial to reduce the size of the food temperature probe 1, making it easier to use and insert into food.
