Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of temperature measuring instruments, and particularly relates to a food temperature probe and a food temperature detection assembly. BACKGROUND

[0002] Roast meat is a dish with unique flavor and is widely loved by people. However, the roaster needs to accurately grasp the fire during the roasting process, so the roaster needs high technical and experience. In order to reduce the difficulty of roasting meat, a food temperature probe is usually configured during roasting meat to monitor the internal temperature of the roast meat or the environment temperature of the roast meat.

[0003] Generally, the food temperature probe includes a shell, a handle and a temperature measuring element. The temperature measuring element is arranged in a cavity formed by the shell and the handle. A user inserts the shell into food by holding the handle. The temperature measuring element is used to detect the temperature of the environment where the food is located and generate a corresponding temperature signal. In the related art, sealing glue is usually used to achieve the relative fixation of the position between the handle and the shell and to achieve the waterproof sealing of the connection position of the handle and the shell. However, since the food temperature probe needs to withstand high temperature for a long time, the sealing glue of the commonly used organic silicon is easy to carbonize in a high temperature environment, resulting in the failure of the bonding performance and the waterproof performance of the sealing glue. SUMMARY

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0037] In a first aspect, the present application provides a food temperature probe, which has good waterproof sealing performance while being resistant to high temperature.

[0038] The food temperature probe includes a shell, a handle, a connecting piece, a pressing piece and a temperature measuring assembly. The shell has a first accommodating cavity. The handle has a second accommodating cavity. The first end of the connecting piece extends into the first accommodating cavity of the shell, and the second end of the connecting piece extends into the second accommodating cavity of the handle. The pressing piece is sleeved around the first end of the connecting piece and the second end of the connecting piece, and is used to seal and connect the shell, the handle and the connecting piece together. The temperature measuring assembly is at least partially arranged in the first accommodating cavity of the shell or the second accommodating cavity of the handle.

[0039] The first end of the shell and the connecting piece are connected together by the press-fit piece, and a sealed connection point can be formed at the end of the side where the cavity opening of the first accommodating cavity of the shell is located, so as to effectively limit the liquid from entering the first accommodating cavity of the shell from the assembly gap between the first end of the shell and the connecting piece, thereby making the food temperature probe have good waterproof sealing performance while being resistant to high temperature. The second end of the handle and the connecting piece are connected together by the press-fit piece, and a sealed connection point can be formed at the end of the side where the cavity opening of the second accommodating cavity of the handle is located, so as to effectively limit the liquid from entering the second accommodating cavity of the handle from the assembly gap between the second end of the handle and the connecting piece, thereby making the food temperature probe have good waterproof sealing performance while being resistant to high temperature.

[0040] The specific structure of the food temperature probe 1 will be described below in combination with the drawings.

[0041] As shown in Figures 1-3 , the food temperature probe 1 comprises a shell 10, a handle 20, a connecting piece 30, a press-fit piece 40 and a temperature measuring assembly. The connecting piece 30 and the press-fit piece 40 are used to seal and connect the shell 10 and the handle 20 together, and the temperature measuring assembly is arranged inside the shell 10 and / or the handle 20.

[0042] Specifically, the shell 10 is one of the shells of the food temperature probe 1, and is used to be inserted into food (such as roast meat). The material of the shell 10 can be but is not limited to metal materials such as stainless steel or aluminum alloy.

[0043] The shell 10 has a first accommodating cavity 10a, and the shell 10 has a long strip-shaped tubular structure with one end open and the other end closed (the hollow area inside the shell 10 is the first accommodating cavity 10a), so that the food temperature probe 1 can be better inserted into the food for temperature measurement when in use.

[0044] The handle 20 is the other shell of the food temperature probe 1, and is used for the user to hold, so as to facilitate the user to insert the food temperature probe 1 into the food and pull the food temperature probe 1 out of the food. The material of the handle 20 can be but is not limited to metal materials such as stainless steel or aluminum alloy.

[0045] The handle 20 has a second accommodating cavity 20a, and the handle 20 has a long strip-shaped tubular structure with one end open and the other end closed (the hollow area inside the handle 20 includes the second accommodating cavity 20a), so that the user can insert the food temperature probe 1 into the food and pull the food temperature probe 1 out of the food by means of the handle 20.

[0046] The connecting piece 30 can be an intermediate connecting structure between the shell 10 and the handle 20.

[0047] Specifically, the first end of the connecting member 30 extends into the first accommodating cavity 10a of the outer shell 10, and the second end of the connecting member 30 extends into the second accommodating cavity 20a of the handle 20. Herein, the first end of the connecting member 30 and the second end of the connecting member 30 are arranged along the length direction of the food temperature probe 1.

[0048] The compression member 40 is one of the sealing members of the food temperature probe 1. On one hand, the compression member 40 is sleeved on the periphery of the first end of the connecting member 30 to seal the assembly gap between the first end of the connecting member 30 and the outer shell 10. On the other hand, the compression member 40 is also sleeved on the periphery of the second end of the connecting member 30 to seal the assembly gap between the second end of the connecting member 30 and the handle 20.

[0049] Specifically, the compression member 40 is used to seal the outer shell 10, the handle 20 and the connecting member 30 together to limit the liquid from entering the first accommodating cavity 10a of the outer shell 10 through the assembly gap between the outer shell 10 and the first end of the connecting member 30, and limit the liquid from entering the second accommodating cavity 20a of the handle 20 through the assembly gap between the handle 20 and the second end of the connecting member 30. For example, the outer shell 10 can be connected with the first end of the connecting member 30 by screwing, and the handle 20 can be connected with the second end of the connecting member 30 by screwing. At this time, the compression member 40 can include an elastic sealing ring or an elastic sealing tube. When the outer shell 10 is screwed with the first end of the connecting member 30, the elastic sealing ring or the elastic sealing tube is compressed to fill the assembly gap between the outer shell 10 and the first end of the connecting member 30, so as to play a sealing role. When the handle 20 is screwed with the second end of the connecting member 30, the elastic sealing ring or the elastic sealing tube is compressed to fill the assembly gap between the handle 20 and the second end of the connecting member 30, so as to play a sealing role.

[0050] The temperature measuring assembly is used to measure the temperature of the food and the temperature of the environment where the food is located. At least part of the temperature measuring assembly can be arranged in the first accommodating cavity 10a of the housing 10, but is not limited to the above, and in other modified embodiments, the temperature measuring assembly 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 first end of the housing 10 and the connecting piece 30 are sealed and connected together by the press-fit piece 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 first end of the housing 10 and the connecting piece 30, thereby making the food temperature probe 1 have good waterproof performance while being resistant to high temperature. The second end of the handle 20 and the connecting piece 30 are sealed and connected together by the press-fit piece 40, and a sealed connection point can be formed at the end of the side where the cavity 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 second end of the handle 20 and the connecting piece 30, thereby making the food temperature probe 1 have good waterproof performance while being resistant to high temperature.

[0051] It can be understood that in some embodiments, the press-fit piece 40 is suitable for deforming under stress to interfere fit with the inner side surface of the housing 10 and the inner side surface of the handle 20, so as to seal and connect the housing 10, the handle 20 and the connecting piece 30 together.

[0052] Here, the specific material of the press-fit piece 40 is not limited, and the designer can reasonably select according to the actual needs, as long as the material can deform under stress and has the performance of resisting high temperature, for example, the material of the press-fit piece 40 can be but is not limited to nano ceramic, metal or stainless steel, etc.

[0053] It should be noted that the pressing component 40 has a tubular structure. During the process of being subjected to force, the cylindrical pressing component 40 will undergo slight deformation. This slight deformation allows the pressing component 40 to have an interference fit with the inner surface of the outer shell 10, forming a sealed connection point at the end of the first receiving cavity 10a of the outer shell 10 on the side where the cavity opening is located. This allows the first end of the outer shell 10 and the connector 30 to be sealed together through the pressing component 40, effectively preventing liquid from entering the first receiving cavity 10a of the outer shell 10 from the assembly gap between the first end of the outer shell 10 and the connector 30. This slight deformation also allows the pressing component 40 to have an interference fit with the inner surface of the handle 20, forming a sealed connection point at the end of the second receiving cavity 20a of the handle 20 on the side where the cavity opening is located. This allows the second end of the handle 20 and the connector 30 to be sealed together through the pressing component 40, effectively preventing liquid from entering the second receiving cavity 20a of the handle 20 from the assembly gap between the second end of the handle 20 and the connector 30.

[0054] like Figures 1-3 As shown, the material design of the housing 10, handle 20, connector 30, and pressing member 40 may include, but is not limited to, one or more of the following embodiments. The following are merely some examples.

[0055] In the first embodiment, the outer casing 10 is made of stainless steel. By designing the outer casing 10 as stainless steel, stainless steel has good thermal conductivity, which allows the food temperature probe 1 to effectively measure the food temperature. On the other hand, stainless steel has good electrical conductivity, which also allows the outer casing 10 to serve as the first charging electrode, enabling effective charging of the food temperature probe 1.

[0056] In the second embodiment, the handle 20 is made of stainless steel. By designing the handle 20 to be made of stainless steel, it is suitable as an antenna for use with the signal transmission element 52 to form an antenna for the food temperature probe 1, so as to send antenna signals to or receive antenna signals from an external terminal. Stainless steel has good conductivity, so that the handle 20 can serve as a second charging electrode to effectively charge the food temperature probe 1.

[0057] In the third embodiment, the connector 30 is made of ceramic. By designing the connector 30 to be made of ceramic, which has good heat insulation properties, heat is blocked from being transferred from the housing 10 to the handle 20, making it easier for the user to insert the food temperature probe 1 into the food and remove the food temperature probe 1 from the food using the handle 20.

[0058] In the fourth embodiment, the material of the compression member 40 is copper. By designing the material of the compression member 40 as copper, the copper has good ductility so as to facilitate the compression member 40 to be deformed under force to be sealingly connected with the shell 10, the handle 20 and the connecting member 30 by interference fit.

[0059] Please refer to Figures 3-5 The compression member 40 includes a sleeve 41 and a barrier 42. The sleeve 41 is sleeved on the periphery of the first end of the connecting member 30, and the sleeve 41 is also sleeved on the periphery of the second end of the connecting member 30. The barrier 42 is arranged on the outer side surface of the sleeve 41. After the compression member 40 is assembled, the barrier 42 is tightly combined with the inner side surface of the shell 10 and the inner side surface of the handle 20 by the friction force generated by interference fit, and the barrier 42 is used to form a sealing path for blocking liquid from entering the first accommodating cavity 10a of the shell 10 and the second accommodating cavity 20a of the handle 20. The barrier 42 can be a solid structure such as a protrusion arranged on the outer side surface of the sleeve 41, or the barrier 42 can be a virtual structure such as a groove formed on the outer side surface of the sleeve 41. By designing the barrier 42 on the outer side surface of the sleeve 41, the barrier 42 can form a sealing path for blocking liquid from entering the first accommodating cavity 10a of the shell 10 and the second accommodating cavity 20a of the handle 20, so as to improve the difficulty of liquid entering the first accommodating cavity 10a of the shell 10 and the second accommodating cavity 20a of the handle 20 from the assembly gap, and further improve the waterproof performance of the food temperature probe 1. It is worth mentioning that when the barrier 42 is a solid structure such as a protrusion arranged on the outer side surface of the sleeve 41, the compression member 40 is deformed under force, and the barrier 42 and the inner side surface of the shell 10 play a role of local interference, and the barrier 42 and the inner side surface of the handle 20 also play a role of local interference.

[0060] When the barrier portion 42 is a solid structure such as a protrusion provided on the outer side surface of the sleeve 41, the barrier portion 42 comprises at least one annular sealing strip 421 provided on the outer side surface of the sleeve 41, each annular sealing strip 421 being arranged around the axis of the sleeve 41. When the number of annular sealing strips 421 is one, the one annular sealing strip 421 is arranged near the side region of the cavity opening of the first accommodating cavity 10a to form the sealing path described above; at this time, the one annular sealing strip 421 arranged near the side region of the cavity opening of the first accommodating cavity 10a is used to accommodate a small amount of liquid entering from the assembly gap, so that the liquid entering from the assembly gap cannot directly enter the first accommodating cavity 10a of the housing 10 and the second accommodating cavity 20a of the handle 20, improving the difficulty of liquid entering the first accommodating cavity 10a of the housing 10 and the second accommodating cavity 20a of the handle 20 from the assembly gap, and further improving the waterproof performance of the food temperature probe 1. When the number of annular sealing strips 421 is multiple, the multiple annular sealing strips 421 are arranged along the axis of the sleeve 41 at intervals, and the interval between the adjacent two annular sealing strips 421 is used to form the sealing path described above; at this time, the interval between the adjacent two 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 cannot directly enter the first accommodating cavity 10a of the housing 10 and the second accommodating cavity 20a of the handle 20, improving the difficulty of liquid entering the first accommodating cavity 10a of the housing 10 and the second accommodating cavity 20a of the handle 20 from the assembly gap, and further improving the waterproof performance of the food temperature probe 1. Wherein, the annular sealing strip 421 can be an annular protrusion or another annular sealing ring; when the annular sealing strip 421 is an annular protrusion, the annular protrusion can be but not limited to detachably fixedly connected with the sleeve 41 by at least one of the following modes such as screwing, clamping or inserting, and the annular protrusion can be but not limited to fixedly connected with the sleeve 41 by the following modes such as 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 is in interference fit with the outer side surface of the sleeve 41.

[0061] When the barrier portion 42 is a virtual structure such as a groove formed on the outer side surface of the sleeve 41, the barrier portion 42 can include at least one annular groove 422 provided on the outer side surface of the sleeve 41, each annular groove 422 being arranged around the axis of the sleeve 41 and being used to form the sealing path described above. When the number of annular grooves 422 is plural, the plural annular grooves 422 are arranged at intervals along the axis of the sleeve 41. By designing at least one annular groove 422 on the outer side surface of the sleeve 41, the annular groove 422 can be used to accommodate a small amount of liquid entering from the assembly gap, so that the liquid entering from the assembly gap cannot directly enter into the first accommodating cavity 10a of the housing 10 and the second accommodating cavity 20a of the handle 20, and the difficulty of the liquid entering into the first accommodating cavity 10a of the housing 10 and the second accommodating cavity 20a of the handle 20 from the assembly gap is increased, so as to further improve the waterproof performance of the food temperature probe 1.

[0062] As shown in Figures 3-5 the first cross section of the housing 10 is perpendicular to the axis of the sleeve 41 in the length direction, and the inner contour line of the first cross section is circular; the second cross section of the handle 20 is perpendicular to the axis of the sleeve 41 in the length direction, and the inner contour line of the second cross section is circular; the third cross section of the connecting piece 30 is perpendicular to the axis of the sleeve 41 in the length direction, and the outer contour line of the third cross section is circular; the fourth cross section of the sleeve 41 is perpendicular to the axis of the sleeve 41 in the length direction, 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 side surface of the connecting piece 30 can be processed by an external cylindrical grinder, so that the outer side surface of the connecting piece 30 can achieve very high precision and cylindricity, and the sleeve 41 is processed by turning, which can achieve higher precision and cylindricity, and is consistent with the precision and cylindricity of the connecting piece 30, so that after the sleeve 41 and the connecting piece 30 are sealingly connected, the assembly gap between the inner side surface of the sleeve 41 and the outer side surface of the connecting piece 30 is small, so as to play a good waterproof role. By designing the inner contour line 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, so that after the housing 10 and the sleeve 41 are sealingly connected, the assembly gap between the inner side surface of the housing 10 and the outer side surface of the sleeve 41 is small, so as to play a good waterproof role. By designing the inner contour line 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, so that after the handle 20 and the sleeve 41 are sealingly connected, the assembly gap between the inner side surface of the handle 20 and the outer side surface of the sleeve 41 is small, so as to play a good waterproof role. By designing the outer contour line of the third cross section of the connecting piece 30 to be circular and the inner annular line of the fourth cross section of the sleeve 41 to be circular, so that after the sleeve 41 and the connecting piece 30 are sealingly connected, the assembly gap between the inner side surface of the sleeve 41 and the outer side surface of the connecting piece 30 is small, so as to play a good waterproof role.

[0063] Specifically, other structural designs of the sleeve 41, the housing 10 and the handle 20 can include, but are not limited to, one or more of the following embodiments.

[0064] In a 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, etc. By reasonably designing the thickness of the sleeve 41, the sleeve 41 expands outwardly to deform during the force process, so as to reduce the assembly gap between the outer side of the sleeve 41 and the inner side of the housing 10, and reduce the assembly gap between the outer side of the sleeve 41 and the inner side of the handle 20, thereby further improving the waterproof performance of the food temperature probe 1. It can be understood that, based on the above thickness range, the greater the thickness of the sleeve 41, the better the waterproof performance of the overall sleeve 41, the connecting piece 30 and the housing 10 formed by interference fit, and the stronger the connection stability, and the better the waterproof performance of the overall sleeve 41, the connecting piece 30 and the handle 20 formed by interference fit, and the stronger the connection stability.

[0065] In a second embodiment, the thickness of the housing 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 housing 10 can 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, etc. By reasonably designing the thickness of the housing 10, the thickness of the housing 10 is not too thin or too thick, so that the housing 10 expands outwardly to deform slightly during the force process, which can not only ensure that the housing 10 and the sleeve 41 form a good seal, but also avoid that the housing 10 extrudes and damages the blocking part 42 arranged on the outer side of the sleeve 41.

[0066] In a third embodiment, the thickness of the part of the handle 20 corresponding to the second accommodating cavity 20a gradually increases from the side close to the cavity opening of the second accommodating cavity 20a to the side away from the cavity opening of the second accommodating cavity 20a. By designing the end of the handle 20 close to the cavity opening of the second accommodating cavity 20a as a thin-walled structure, the end of the handle 20 close to the cavity opening of the second accommodating cavity 20a expands outwardly to deform slightly during the force process, which can not only ensure that the handle 20 and the sleeve 41 form a good seal, but also avoid that the handle 20 extrudes and damages the blocking part 42 arranged on the outer side of the sleeve 41.

[0067] As Figures 3-5As shown, the connecting piece 30 comprises a connecting portion 31 and a stop portion 32; the connecting portion 31 extends along an axis O-O of a length direction D of the pressing piece 40 (specifically, the sleeve 41 described above); the stop portion 32 is arranged on the periphery of the connecting portion 31 to divide the connecting portion 31 into a first connecting section 311 and a second connecting section 312, the first connecting section 311 extends into the first accommodating cavity 10a of the shell 10 as a first end of the connecting piece 30, and the second connecting section 312 extends into the second accommodating cavity 20a of the handle 20 as a second end of the connecting piece 30.

[0068] The pressing piece 40 (specifically, the sleeve 41 described above) comprises a first sleeve 411 and a second sleeve 412; the first sleeve 411 is sleeved on the periphery of the first connecting section 311; and the second sleeve 412 is sleeved on the periphery of the second connecting section 312. The stop portion 32 is used to limit the first sleeve 411 and the second sleeve 412 from moving towards each other to abut against each other.

[0069] The stop portion 32 can be, but is not limited to, detachably fixedly connected with the connecting portion 31 by at least one of the following modes: screwing, clamping, or inserting; and the stop portion 32 can be, but is not limited to, fixedly connected with the connecting portion 31 by the following modes: riveting, injection molding, or 3D printing.

[0070] By designing the stop portion 32 on the periphery of the connecting portion 31, the stop portion 32 divides the connecting portion 31 into the first connecting section 311 and the second connecting section 312, the first connecting section 311 is used to allow the first sleeve 411 to be sleeved thereon as the first end of the connecting piece 30, and the second connecting section 312 is used to allow the second sleeve 412 to be sleeved thereon as the second end of the connecting piece 30. The design of the stop portion 32 can realize assembly stop between the first sleeve 411 and the first connecting section 311, thereby facilitating assembly between the shell 10, the first sleeve 411, and the first connecting section 311; and the design of the stop portion 32 can also realize assembly stop between the second sleeve 412 and the second connecting section 312, thereby facilitating assembly between the handle 20, the second sleeve 412, and the second connecting section 312.

[0071] The shell 10 has a first surface 10b arranged towards the handle 20, and the first accommodating cavity 10a is formed by extending inwardly from the first surface 10b of the shell 10; the handle 20 has a second surface 20b arranged towards the shell 10, and the second accommodating cavity 20a is formed by extending inwardly from the second surface 20b of the handle 20. The stop portion 32 comprises a stop ring 321 arranged on the periphery of the connecting portion 31, when the shell 10, the handle 20, the connecting piece 30, and the pressing piece 40 are sealingly connected together, one end surface of the stop ring 321 is attached to the first surface 10b of the shell 10, and the other end surface of the stop ring 321 is attached to the second surface 20b of the handle 20.

[0072] The stop ring 321 can be detachably connected with the connecting part 31 by at least one of screwing, clamping or inserting, but is not limited to these. The stop ring 321 can also be fixedly connected with the connecting part 31 by riveting, injection molding or 3D printing, but is not limited to these.

[0073] When the shell 10, the handle 20, the connecting part 30 and the pressing part 40 are sealed and connected together, the stop ring 321 can realize assembly stop between the shell 10 and the first connecting section 311 by abutting one end surface of the stop ring 321 with the first surface 10b of the shell 10 and abutting the other end surface of the stop ring 321 with the second surface 20b of the handle 20, so as to facilitate assembly between the shell 10, the first sleeve 411 and the first connecting section 311. Similarly, the stop ring 321 can also realize assembly stop between the handle 20 and the second connecting section 312, so as to facilitate assembly between the handle 20, the second sleeve 412 and the second connecting section 312. By designing the stop part 32 as the stop ring 321, the one end surface of the stop ring 321 abuts with the first surface 10b of the shell 10 to realize circumferential sealing between the stop ring 321 and the shell 10, so as to further improve the waterproof performance of the food temperature probe 1. Similarly, the other end surface of the stop ring 321 abuts with the second surface 20b of the handle 20 to realize circumferential sealing between the stop ring 321 and the handle 20, so as to further improve the waterproof performance of the food temperature probe 1.

[0074] As shown in the embodiment, Figure 5 the stop part 32 is the stop ring 321. However, please refer to Figure 6 in other embodiments, the stop part 32 can also be at least one stop protrusion. Specifically, the stop part 32 can include a plurality of stop protrusions 322, which are arranged at intervals around the axis O-O of the sleeve 41 on the periphery of the connecting part 31. At this time, the first surface 10b of the shell 10 protrudes towards the handle 20 to form a plurality of first sealing protrusions 11 arranged at intervals, and the second surface 20b of the handle 20 can protrude towards the shell 10 to form a plurality of second sealing protrusions 21 arranged at intervals, the first sealing protrusions 11 and the second sealing protrusions 21 being used to seal the interval space 323 between two adjacent stop protrusions 322.

[0075] The principle of the embodiment of the present application for blocking a small amount of liquid from entering the containing cavity of the handle 20 and then entering the first containing cavity 10a of the shell 10 from the assembly gap will be described below. Figure 5 , 7 and Figure 8

[0076] As shown in the embodiment, Figure 5 and Figure 7 ​As shown, when a small amount of liquid can enter from the assembly gap, a part of the liquid will enter the gap between the outer side surface of the first sleeve 411 and the inner side surface of the shell 10, at this time, due to the design of the blocking part 42, the blocking part 42 can effectively block the liquid from further entering the first accommodating cavity 10a of the shell 10 from the gap between the outer side surface of the first sleeve 411 and the inner side surface 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 surface of the first sleeve 411 and the outer side surface of the first connecting section 311, at this time, in order to effectively block the liquid from further entering the first accommodating cavity 10a of the shell 10 from the gap between the inner side surface of the first sleeve 411 and the outer side surface 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 part 3111 and a second part 3112 connected with the first part 3111, the first part 3111 is farther away from the second connecting section 312 than the second part 3112; the first sleeve 411 is sleeved on the periphery of the second part 3112. The connector 30 further includes a clamping part 33, which is arranged on the first part 3111. The food temperature probe 1 further includes a first sealing member 60, which is arranged on the clamping part 33 to seal the gap between the first part 3111 and the inner side surface of the shell 10.

[0077] The clamping part 33 can be a solid structure such as a clamping protrusion arranged on the first part 3111, or a virtual structure such as a clamping groove formed on the first part 3111.

[0078] The first sealing member 60 is used to seal the gap between the first part 3111 and the inner side surface of the shell 10, so as to avoid the liquid from further entering the first accommodating cavity 10a of the shell 10. The first sealing member 60 can be but is not limited to a sealing ring or a sealing adhesive layer 71.

[0079] By designing the first sealing member 60, the first sealing member 60 is used to seal the gap between the first part 3111 and the inner side surface of the shell 10, at this time, the first sealing member 60 can not only effectively block the liquid from further entering the first accommodating cavity 10a of the 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 also block the liquid from further entering the first accommodating cavity 10a of the shell 10 from the gap between the outer side surface of the first sleeve 411 and the inner side surface of the shell 10, so as to further improve the waterproof performance of the food temperature probe 1.

[0080] Specifically, as shown, Figure 5 and Figure 8As shown, the clamping portion 33 comprises an annular clamping groove 331 provided on the periphery of the first portion 3111, which surrounds the axis of the sleeve 41. The first sealing member 60 comprises an annular sealing ring 61, which is embedded in the annular clamping groove 331 and is in interference fit with the inner side of the housing 10 to seal the gap between the first portion 3111 and the inner side of the housing 10. By designing the clamping portion 33 as the annular clamping groove 331 and the first sealing member 60 as the annular sealing ring 61, the annular sealing ring 61 is embedded in the annular clamping groove 331 to achieve the relative fixation of the position between the annular sealing ring 61 and the first portion 3111, and the annular sealing ring 61 is in interference fit with the inner side of the housing 10 to seal the gap between the first portion 3111 and the inner side of the housing 10. At this time, the annular sealing ring 61 not only can effectively block the liquid from further entering into the first accommodating cavity 10a of the housing 10 from the gap between the inner side of the first sleeve 411 and the outer side of the second portion 3112, but also can block the liquid from further entering into the first accommodating cavity 10a of the housing 10 from the gap between the outer side of the first sleeve 411 and the inner side of the housing 10, so as to further improve the waterproof performance of the food temperature probe 1.

[0081] Please refer to Figure 2 、 Figure 3 and Figure 9 , the temperature measuring assembly is used for measuring temperature and generating corresponding temperature sensing signals, which comprises a temperature measuring body 51. Specifically, the temperature measuring body 51 is used for measuring the temperature of the environment where the food is located, and the temperature measuring body 51 is in the shape of a long strip extending along the length direction of the food temperature probe 1. The food temperature probe 1 further comprises a signal transmission element 52, which is used for transmitting, emitting and / or receiving antenna signals, and the signal transmission element 52 has a cavity 52a for accommodating the temperature measuring body 51. The food temperature probe 1 further comprises a circuit board 81, which is electrically connected with the temperature measuring body 51 and the signal transmission element 52. The handle 20 further has a third accommodating cavity 20c, which is formed from the cavity bottom wall of the second accommodating cavity 20a and extends away from the cavity opening of the second accommodating cavity 20a. The connecting piece 30 is in a tubular structure. The signal transmission element 52 is wrapped around the periphery of the temperature measuring body 51 to form a combined body, which passes through the barrel cavity of the connecting piece 30 and extends into the third accommodating cavity 20c of the handle 20. Of course, the temperature measuring assembly can further comprise a temperature sensing element 96 electrically connected with the circuit board 81, which can be arranged adjacent to the tip of the food temperature probe 1 and used for measuring the temperature inside the food. It can be understood that the temperature sensing signals generated by the temperature measuring assembly can include the temperature sensing signals obtained by the temperature measuring body 51 and the temperature signals obtained by the temperature sensing element 96.

[0082] It is understandable that the specific form of the temperature sensing signal generated by the temperature sensing body 51 will vary depending on the type of temperature sensing body 51. For example, when the temperature sensing body 51 is a thermistor, the temperature sensing signal generated by the thermistor is a resistance signal; as another example, when the temperature sensing body 51 is a digital sensor, the temperature sensing signal generated by the digital sensor is a digitally encoded signal; and as yet another example, when the temperature sensing body 51 is a thermocouple 511, the temperature sensing signal generated by the thermocouple 511 is a voltage signal. In this embodiment of the application, the temperature sensing body 51 is a thermocouple 511.

[0083] The signal transmission element 52 is suitable for transmitting, transmitting, and / or receiving antenna signals. In one embodiment, the signal transmission element 52 can function as the antenna of the food temperature probe 1 independently, or it can be electrically connected to other conductive media to function as the antenna of the food temperature probe 1 together with other conductive media, thereby transmitting, transmitting, and / or receiving antenna signals. Transmission refers to wirelessly sending antenna signals, and reception refers to wirelessly receiving other antenna signals sent by an external terminal. Antenna signals may include, but are not limited to, radio frequency signals.

[0084] Of course, such as Figure 2 and Figure 3 As shown, the food temperature probe 1 may also include an elastic connector 94. The elastic connector 94 is used to fix 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 generate an elastic restoring force in the radial direction of the signal transmission element 52 by deformation to fix the signal transmission element 52. This effectively fixes the signal transmission element 52, preventing the signal transmission element 52, which acts as an antenna, from loosening, and enabling 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 is not described in detail here; designers can design it reasonably according to actual needs.

[0085] 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. 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. 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.

[0086] When the elastic connecting piece 94 is 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 formed only by the part of the signal transmission element 52 located in the handle 20, and if the handle 20 is made of a conductive material such as stainless steel, the antenna of the food temperature probe 1 can be formed by the part of the signal transmission element 52 located in the handle 20 and the handle 20 (the signal transmission element 52 is directly electrically connected with the handle 20).

[0087] As shown in Figure 10 and Figure 11 , 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, and the food temperature probe 1 can further include an insulating piece 53, which is used to avoid the temperature measuring body 51 and the signal transmission element 52 from being directly in contact to cause electrical short circuit, and 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 piece 53 can include but is not limited to an insulating layer, an insulating gasket or an insulating sleeve. The material of the insulating piece 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 ceramic, silica ceramic, quartz glass, borosilicate glass, natural mica, laminated mica layer, etc. The temperature measuring body 51 is connected with the signal transmission element 52 into a whole through the insulating piece 53, and the insulating piece 53 serves as an intermediate connecting structure between the temperature measuring body 51 and the signal transmission element 52, which is used to realize the connection between the temperature measuring body 51 and the signal transmission element 52, so that the temperature measuring body 51 and the signal transmission element 52 are connected and formed into a whole through the insulating piece 53. In the embodiment of the present application, the connection between the temperature measuring body 51 and the signal transmission element 52 is realized by pouring and curing insulating slurry in the cavity 52a of the signal transmission element 52 to form an insulating layer.

[0088] As shown in Figure 2 , the shell 10 can be electrically connected with the electrical contact 81a on the circuit board 81, so that the shell 10 is suitable to be used as a first charging electrode; the signal transmission element 52 is electrically connected with the handle 20, so that the handle 20 is suitable to be used as a second charging electrode; one of the first charging electrode and the second charging electrode is a charging positive electrode, and the other of the first charging electrode and the second charging electrode is a charging negative electrode. In this way, the materials of the shell 10 and the handle 20 are designed to be stainless steel, so that the shell 10 and the handle 20 form an effective charging loop. In the embodiment of the present application, the shell 10 is used as the charging negative electrode, and the handle 20 is used as the charging positive electrode. It should be noted that at this time, the shell 10 and the handle 20 are both conductive materials, and the shell 10 and the handle 20 are insulated and connected through the connecting piece 30.

[0089] Of course, when the shell 10 and the handle 20 are both non-conductive materials, neither the shell 10 nor the handle 20 serves as a charging electrode, and two charging pins are arranged on the shell 10 and / or the handle 20, which serve as the first charging electrode and the second charging electrode and are electrically connected with the circuit board 81. When the shell 10 is a conductive material and the handle 20 is a non-conductive material, the shell 10 can serve as the first charging electrode, and one charging pin is arranged on the handle 20, which serves as the second charging electrode.

[0090] It can be understood that, as Figure 12 and Figure 13 shown, when a small amount of liquid can enter from the assembly gap, 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, and at this time, due to the design of the blocking part 42, the blocking part 42 can effectively block the liquid from further entering the second accommodating cavity 20a and the third accommodating cavity 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 cavity 20a and the third accommodating cavity 20c of the handle 20, and at this time, in order to avoid the liquid entering the third accommodating cavity 20c of the handle 20 from directly contacting the temperature measuring main body 51. Therefore, as Figure 9 shown, the signal transmission element 52 includes a tube side wall 521 and a tube end wall 522, the tube end wall 522 is sealingly connected with the tube side wall 521 close to the end of the handle 20 (specifically, the end of the tube side wall 521 located in the third accommodating cavity 20c of the handle 20), and the tube end wall 522 and the tube side wall 521 together enclose a cavity 52a for accommodating the temperature measuring main body 51. By designing the signal transmission element 52 to include the tube side wall 521 and the tube end wall 522, the tube end wall 522 and the tube side wall 521 enclose the cavity 52a for accommodating the temperature measuring main body 51, so that the temperature measuring main body 51 is isolated from direct contact with the liquid entering the third accommodating cavity 20c of the handle 20, thereby providing good protection for the temperature measuring main body 51. By sealingly connecting the tube end wall 522 with the end of the tube side wall 521, the waterproof sealing performance of the signal transmission element 52 for the temperature measuring main body 51 can be further improved.

[0091] Specifically, the circuit board 81 can be provided with a wireless communication chip (such as a Bluetooth chip) for modulating the temperature sensing signal of the temperature measuring assembly into an antenna signal, when the signal transmission element 52, the elastic connecting element 94 and the handle 20 form an antenna of the food temperature probe 1, the antenna signal is transmitted to the elastic connecting element 94 via the signal transmission element 52, and then transmitted to the handle 20 by the elastic connecting element 94, and then transmitted to the outside by the handle 20. The terminal (such as a mobile phone), the user can understand the temperature of the environment where the food is located according to the relevant temperature data displayed by the external terminal.

[0092] It can be understood that, as shown in Figures 12-15 , since the connecting element 30 is provided in a tubular structure, after the 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 element 30 and the outer side of the signal transmission element 52, and then enter the first accommodating cavity 10a of the shell 10. In order to prevent the liquid in the second accommodating cavity 20a and the third accommodating cavity 20c of the handle 20 from entering the first accommodating cavity 10a of the shell 10 in reverse, the design is as shown in Figure 8 , the food temperature probe 1 further comprises a second sealing element 70, which is arranged at one end of the connecting element 30 away from the cavity opening of the second accommodating cavity 20a of the handle 20, and the second sealing element 70 is used to seal the gap between the signal transmission element 52 and the connecting element 30.

[0093] Specifically, the second sealing element 70 comprises a sealing glue layer 71, which is arranged in a ring structure around the axis of the connecting element 30. By designing the ring-shaped sealing glue layer 71, on the one hand, the ring-shaped sealing glue layer 71 has sealing property to seal the gap between the signal transmission element 52 and the connecting element 30, effectively preventing the liquid in the second accommodating cavity 20a and the third accommodating cavity 20c of the handle 20 from entering the first accommodating cavity 10a of the shell 10 in reverse, and on the other hand, the ring-shaped sealing glue layer 71 has adhesion to fix the relative position between the signal transmission element 52 and the connecting element 30, effectively reducing the assembly difficulty between the signal transmission element 52 and the connecting element 30. It should be noted that in order to improve the service life of the sealing glue layer 71, the selected glue should be able to realize tight and seamless bonding on various materials, maintain good bonding effect in various environments, adapt to the slight deformation of different objects in use, and have good high temperature resistance. In this way, the food temperature probe 1 still has good sealing effect in high temperature working environment.

[0094] Of course, in other embodiments, the second seal 70 can also be a sealing ring or a combination of a sealing ring and a sealing adhesive layer 71, at this time the sealing ring is used to seal the gap between the signal transmission element 52 and the connecting piece 30, and the signal transmission element 52 and the connecting piece 30 can be but not limited to fixed in position by screwing, clamping, plugging or bonding and the like.

[0095] It is worth mentioning that in the present application, by designing the shell 10, the handle 20, the connecting piece 30 and the pressing piece 40 to be sealed and connected together by force interference fit to form the first heavy seal, by designing the first seal 60 to form the second heavy seal, and by designing the second seal 70 to form the third heavy seal, the three heavy seals cooperate with each other, so that the food temperature probe 1 is resistant to high temperature and also has excellent waterproof sealing performance.

[0096] The second aspect, as Figure 16 shown, the present application proposes a food temperature detection assembly 1A, which can communicate with an external terminal 3, and a user can interact 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 arranged on the storage device 2, and the food temperature probe 1 adopts the food temperature probe 1 described in the above embodiments. Specifically, the storage device 2 has a storage groove 2a, and the food temperature probe 1 is detachably arranged in the storage groove 2a of the storage device 2.

[0097] The storage device 2 can be used to store the food temperature probe 1 when it is idle, and the storage device 2 can also charge the food temperature probe 1 and the food temperature probe 1. The specific structure of the food temperature probe 1 is referred to the above embodiments, since the present food temperature detection assembly 1A adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0098] The receiving device 2 can also serve as a relay station between the food temperature probe 1 and the external terminal 3, at this time the food temperature probe 1 realizes communication with the external terminal 3 through the receiving device 2, the handle 20 as an antenna can first send an antenna signal to the receiving device 2, and the receiving device 2 sends the antenna signal to the external terminal 3, so that the user can understand the temperature of the environment where the food is located according to the relevant temperature data displayed by the external terminal 3, on the contrary, the external terminal 3 can also send an antenna signal to the receiving device 2, and the receiving device 2 sends the antenna signal to the food temperature probe 1, so that the food temperature probe 1 performs corresponding operation according to the antenna signal. As a relay station, the receiving device 2 can process the received signal, eliminate part of the interference and noise, improve the clarity and integrity of the signal, so that the external terminal 3 can more accurately receive the data sent by the food temperature probe 1. As a relay station, the receiving device 2 can be placed in a relatively appropriate position to avoid these interference sources and shields, and ensure that the signal transmission between the food temperature probe 1 and the external terminal 3 is smooth. As a relay station, the food temperature probe 1 only needs to communicate with the receiving device 2 at close range, and its design can be more simplified, reducing cost and power consumption, and also conducive to reducing the size of the food temperature probe 1, making it more convenient to use and insert into food.
