[0005] In one embodiment, the inner diameter of the first mounting hole gradually increases from the end closer to the handle toward the end farther from the handle.

[0007] In one embodiment, the first connector includes an elastic sealing portion, and the second connector includes a guide portion and a pushing portion. The guide portion is inserted into the first mounting hole and is movable along the axial direction of the temperature probe. The pushing portion is located at the end of the guide portion away from the handle. The end of the first connector away from the handle has a first end face. The pushing portion is used to press against the first end face during the movement of the second connector along the axial direction of the temperature probe, so that the elastic sealing portion deforms and abuts against the inner wall of the syringe.

[0008] In one embodiment, the first connector further includes a pressing part, which is disposed at the end of the elastic sealing part away from the handle. The pushing part is used to abut against the pressing part, and the pressing part is used to press against the elastic sealing part under the action of external force, so as to deform the elastic sealing part.

[0009] In one embodiment, the first connector includes a body and a limiting block connected to each other. The limiting block is located at one end of the body near the handle. The body is inserted into the syringe. The end of the syringe near the handle has a second end face. The end of the limiting block near the body overlaps the second end face. At least a portion of the handle is inserted into the first mounting hole. The handle abuts against the end of the limiting block away from the second end face.

[0010] In one embodiment, the outer diameter of the limiting block is larger than the outer diameter of the body to form a first limiting step between the body and the limiting block, and the second end face abuts against the first limiting step; a protrusion is provided at one end of the limiting block near the second end face, and a limiting groove is opened on the second end face to cooperate with the protrusion, and the protrusion is inserted into the limiting groove.

[0011] In one embodiment, the second connector has a second mounting hole for inserting the handle. The handle includes a first connecting portion, a second connecting portion, and a third connecting portion arranged sequentially along the axial direction of the syringe. The first connecting portion is located at one end of the handle near the syringe. The first connecting portion and the second connecting portion are rotatably disposed in the first mounting hole. At least a portion of the first connecting portion is inserted into the second mounting hole. The first connecting portion is threadedly connected to the inner wall of the second mounting hole. The third connecting portion overlaps the end face of the first connector near the handle.

[0012] In one embodiment, the temperature probe further includes a waterproof component, which is sleeved around the first connecting portion and located between the second connecting portion and the second connecting member. The waterproof component is used to seal the first connecting member to the handle; and / or, the outer diameter of the second connecting portion is larger than the outer diameter of the first connecting portion to form a second limiting step between the second connecting portion and the first connecting portion, and the waterproof component elastically abuts against the second limiting step and the second connecting member.

[0015] The technical solution of this invention employs a syringe, a handle, and a connecting assembly in a temperature probe. The handle is rotatably mounted on one end of the syringe. The connecting assembly is located at the end of the syringe near the handle, and includes a first connector and a second connector. The first connector is at least partially located inside the syringe and has a first mounting hole. The second connector is inserted into the first mounting hole and sleeved around the handle. The handle and the second connector are connected in a driving manner, allowing the handle to rotate and drive the second connector to move axially along the syringe, causing the first connector to deform and abut against the inner wall of the syringe. This allows the handle to be connected along the syringe via the connecting assembly. Rotation of the handle drives the second connector in the connecting assembly to move axially along the syringe, gradually abutting against the first connector fixedly mounted on the syringe and causing the first connector to deform, thereby tightening the gap between the first connector and the syringe to achieve a waterproof seal for the temperature probe housing. In this process, the sealing assembly of the temperature probe can be achieved simply by rotating the handle, simplifying the installation steps and reducing the difficulty of sealing the temperature probe.

[0036] This invention proposes a temperature probe 100.

[0037] Please see Figures 1 to 13 In one embodiment of the present invention, the temperature probe 100 includes: a syringe 1, a handle 2, and a connecting component 3; the handle 2 is rotatably mounted on one end of the syringe 1; the connecting component 3 is disposed on the end of the syringe 1 near the handle 2, and the connecting component 3 includes a first connector 31 and a second connector 32. The first connector 31 is at least partially located inside the syringe 1 and has a first mounting hole 311. The second connector 32 is inserted into the first mounting hole 311 and sleeved on the periphery of the handle 2. The handle 2 and the second connector 32 are connected in a transmission manner, so that the handle 2 can drive the second connector 32 to move axially along the syringe 1 by rotation, thereby causing the first connector 31 to deform and abut against the inner wall of the syringe 1.

[0038] In this embodiment, the syringe 1 is a long and slender cylindrical structure, typically made of metal to ensure rigidity and thermal conductivity. One end of the syringe 1 has an opening to accommodate the connecting component 3 and the connecting handle 2. The handle 2 is rotatably mounted to the rear end of the syringe 1, ensuring that the handle 2 can rotate freely around the axis of the syringe 1, but does not move along the axis. At least a portion of the first connecting member 31 is housed inside the syringe 1. Since in this embodiment, the handle 2 is connected to the positive terminal of the internal circuit of the temperature probe 100, and the syringe 1 is connected to the negative terminal of the internal circuit, to prevent short circuits caused by contact and conduction between the syringe 1 and the handle 2, the main body material of the connecting component 3 can be made of insulating plastic or silicone rubber. This allows the first connecting member 31 to deform under external force while preventing short circuits caused by the handle 2 connecting to the syringe 1. The first connecting member 31 has a first mounting hole 311, which extends axially along the first connecting member 31. The second connector 32 is inserted into the first mounting hole 311 from the end away from the handle 2 and is fitted around the handle 2. The second connector 32 is restricted from rotation in the first mounting hole 311 and can only slide along its axial direction. The second connector 32 has an internal thread, and the outer wall of the handle 2 has an external thread that mates with the internal thread. This allows the rotational motion of the handle 2 to be converted into linear motion of the second connector 32 along the axis of the syringe 1 through the threaded connection structure when the user rotates the handle 2.

[0039] Understandably, when the second connector 32 moves axially, the portion inserted into the first mounting hole 311 can apply a radial thrust to the first connector 31. Under this radial thrust, the first connector 31 undergoes structural deformation such as expansion or stretching, and its outer surface thus generates positive pressure against the inner wall of the syringe 1, thereby achieving tight contact and circumferential and axial fixation through friction. Furthermore, during subsequent daily use, if the sealing structure at the connection between the handle 2 and the syringe 1 is found to be loose, the user can manually rotate the handle 2 to re-tighten the first connector 31 against the inner wall of the syringe 1, thereby reducing the maintenance difficulty of the temperature probe 100 and extending its service life.

[0040] The technical solution of the present invention employs a syringe 1, a handle 2, and a connecting assembly 3 in a temperature probe 100. The handle 2 is rotatably mounted on one end of the syringe 1. The connecting assembly 3 is located at one end of the syringe 1 and includes a first connecting member 31 and a second connecting member 32. The first connecting member 31 is at least partially located inside the syringe 1 and has a first mounting hole 311. The second connecting member 32 is inserted into the first mounting hole 311 and sleeved around the handle 2. The handle 2 and the second connecting member 32 are connected in a transmission manner. The handle 2 can drive the second connecting member 32 to move axially along the syringe 1 by rotation, thereby causing the first connecting member 31 to move axially. 31 deforms and abuts against the inner wall of the syringe 1; this allows the handle 2 to be connected along the syringe 1 via the connecting assembly 3. By rotating the handle 2, the second connecting member 32 in the connecting assembly 3 can be driven to move axially along the syringe 1, gradually abutting against the first connecting member 31 fixedly installed on the syringe 1 and causing the first connecting member 31 to deform, thereby squeezing the gap between the first connecting member 31 and the syringe 1 to achieve a waterproof seal for the temperature probe 100 housing. In this process, the temperature probe 100 can be sealed and assembled simply by rotating the handle 2, simplifying the installation steps of the parts and reducing the difficulty of sealing and assembling the temperature probe 100.

[0041] Please see Figure 1 , Figures 8 to 11 In one embodiment, the inner diameter of the first mounting hole 311 gradually increases from the end near the handle 2 to the end away from the handle 2. The continuous increase in the inner diameter of the first mounting hole 311 from the end near the handle 2 to the end away from the handle 2 forms a tapered or beveled hole structure, so that the cross-section of the first mounting hole 311 exhibits a consistent linear or specific curvature change along its axial direction, thereby forming a continuous guide slope on the inner wall of the hole. When the second connector 32 is inserted into the first mounting hole 311 and moves axially, its outer surface continuously contacts and interacts with the inner wall of the hole; as the second connector 32 moves towards the area with a smaller inner diameter within the hole, the guide slope gradually converts the axial thrust applied by the second connector 32 into a radial expansion force on the hole wall of the first connector 31. This arrangement makes the deformation process of the first connector 31 more controllable and uniform, allowing for stepless adjustment of the clamping degree of the first connector 31, improving the mechanical efficiency and structural reliability of the locking action.

[0042] Please see Figure 1 , Figure 2 , Figure 5 , Figures 8 to 9In one embodiment, the outer diameter of the second connector 32 gradually increases from the end near the handle 2 to the end away from the handle 2; alternatively, the outer wall of the second connector 32 is provided with a protrusion 321, which is arranged around the outer wall of the second connector 32 and is used for interference fit with the inner wall of the first mounting hole 311. In one embodiment, the outer wall of the second connector 32 can be configured as a conical structure that matches the shape of the inner hole of the first mounting hole 311 to avoid affecting the axial movement of the second connector 32 in the first mounting hole 311. When the handle 2 is rotated, the end of the second connector 32 with a larger outer diameter can move towards the end with a smaller inner diameter in the first mounting hole 311, thereby gradually interfering with the inner wall of the first mounting hole 311 and squeezing the first connector 31. The first connector 31 deforms radially outward under the pressure of the second connector 32, thereby squeezing the gap between it and the syringe 1 and achieving a seal between the connecting assembly 3 and the syringe 1.

[0043] Please see Figure 1 , Figure 3 , Figures 6 to 7 , Figures 10 to 11 In another embodiment, the first connector 31 adopts a stepped structure, and the outer wall of the second connector 32 is provided with an annular protrusion 321. The protrusion 321 completely surrounds the circumference of the second connector 32, and its outer diameter is larger than the outer diameter of the second connector 32, and also larger than at least part of the inner diameter of the first mounting hole 311 in its normal state, thereby forming an interference fit with the inner wall of the first mounting hole 311 in the assembled state. When the handle 2 drives the second connector 32 to move axially, the protrusion 321 presses against the corresponding section of the first mounting hole 311, causing the first connector 31 to undergo radial deformation. Both structures can cause the first connector 31 to undergo the required elastic deformation, so that its outer surface abuts against the inner wall of the syringe 1.

[0044] Please see Figure 1 , Figure 4 , Figures 12 to 13 In one embodiment, the first connector 31 includes an elastic sealing portion 312, and the second connector 32 includes a guide portion 322 and a pushing portion 323. The guide portion 322 is inserted into the first mounting hole 311 and can move along the axial direction of the temperature probe 100. The pushing portion 323 is located at the end of the guide portion 322 away from the handle 2. The end of the first connector 31 away from the handle 2 has a first end face 317. The pushing portion 323 is used to press against the first end face 317 during the movement of the second connector 32 along the axial direction of the temperature probe, so that the elastic sealing portion 312 deforms and abuts against the inner wall of the syringe 1.

[0045] In this embodiment, the first end face 317 is the end face of the first connector 31 away from the handle 2; the elastic sealing part 312 is used to deform under external force to press against and seal against the inner wall of the syringe 1. The elastic sealing part 312 can be made of rubber or silicone material with elasticity. Its initial external dimensions are slightly smaller than the inner diameter of the syringe 1, so that it can maintain a clearance fit with the inner wall of the syringe 1, making it easy to insert the elastic sealing part 312 into the syringe 1. The second connector 32 includes a guide part 322 and a push part 323 integrally formed and connected to each other. The guide part 322 can be a columnar or sleeve structure and is inserted into the first mounting hole 311, forming a sliding fit with the hole wall to ensure that the second connector 32 can move smoothly along the axial direction of the temperature probe 100 and avoid radial shaking. The pusher portion 323 is located at the end of the guide portion 322 away from the handle 2. Its structure is a radially expanding annular flange. The outer diameter of the pusher portion 323 is larger than the outer diameter of the guide portion 322, so that the pusher portion 323 can generate a thrust on the elastic sealing portion 312 from the end face away from the handle 2. Under the thrust of the pusher portion 323, the elastic sealing portion 312 is axially compressed, resulting in radial expansion deformation, thereby gradually and tightly abutting against the inner wall of the syringe 1, forming a seal and circumferential fixation. This structure prevents external fluid from entering the probe interior from the connection point, achieving a waterproof seal for the temperature probe 100 housing.

[0046] See Figure 2 , Figure 4 , Figure 12 , Figure 13In one embodiment, the first connecting member 31 further includes a pressing part 313, which is located at the end of the elastic sealing part 312 away from the handle 2. A pushing part 323 abuts against the pressing part 313. The pressing part 313 presses against the elastic sealing part 312 under external force, causing deformation of the elastic sealing part 312. The pressing part 313 is made of a relatively hard material, such as hard plastic or a metal ring, and is used to press against the end face of the elastic sealing part 312 away from the handle 2. After being pressed, due to the hardness of the material, its positive compression deformation is small; its main function is to cause displacement change, squeezing the elastic sealing part 312 to deform it. The pressing part 313 ensures that the axial thrust from the pushing part 323 is smoothly transmitted to the first connecting member 31, avoiding thrust deviation or uneven local force on the elastic sealing part 312, which would affect the sealing effect. The rigid structure of the pressure-resistant part 313 can also limit the excessive axial displacement or unstable deformation of the elastic sealing part 312 during the pressure process, ensuring that its deformation mainly occurs in the radial direction, thereby improving the repeatability and reliability of the sealing action and preventing the elastomer from being damaged due to excessive torsion. By adding the pressure-resistant part 313, the functions of the driving and deformation components are separated. The pushing part 323 of the second connecting member 32 applies a force to the pressure-resistant part 313 of the first connecting member 31, causing the elastic sealing part 312 to deform, which improves the force transmission efficiency and deformation controllability, and ensures that the sealing system works more stably and durablely.

[0047] In this embodiment, multiple pressure-blocking portions 313 and elastic sealing portions 312 are alternately arranged along the axial direction of the temperature probe 100, forming a multi-layered composite structure that alternately arranges along the axial direction of the temperature probe 100. The alternately stacked pressure-blocking portions 313 and elastic sealing portions 312 form a series of continuous sealing units along the axial direction of the temperature probe 100, each sealing unit including a pressure-blocking portion 313 and an elastic sealing portion 312. Under the axial constraint and support of the pressure-blocking portions 313 on both sides, each elastic sealing portion 312 can independently undergo controllable radial expansion deformation when subjected to external thrust. When the entire assembly is compressed, each layer of elastic sealing portions 312 can deform successively or synchronously, thereby forming multiple continuous sealing rings on the inner wall of the syringe 1, thereby improving the sealing redundancy and reliability of the system. Even if the performance of a single sealing layer decreases due to wear or local defects, the remaining sealing layers can still effectively block fluid, ensuring the durability of the seal under complex working conditions or long-term use. Meanwhile, this design allows for control of the sealing performance and compression stroke of the temperature probe 100 housing during subsequent use by adjusting the number of layers, material hardness, and cross-sectional shape, in order to meet different pressure ratings or assembly tolerance requirements.

[0048] See Figure 2 , Figure 7In one embodiment, the first connector 31 includes a body 314 and a limiting block 315 connected to each other. The limiting block 315 is located at the end of the body 314 near the handle 2. The body 314 is inserted into the syringe 1. The end of the syringe 1 near the handle 2 has a second end face 11. The end of the limiting block 315 near the body 314 overlaps the second end face 11. At least a portion of the handle 2 is inserted into the first mounting hole 311, and the handle 2 abuts against the end of the limiting block 315 away from the second end face 11. In this embodiment, the body 314 and the limiting block 315 are integrally formed or connected to each other by welding. The cross-sectional shape and size of the body 314 match the cross-sectional shape and size of the inner hole of the syringe 1. The limiting block 315 is located at the end of the body 314 near the handle 2, and its radial dimension is larger than the inner diameter of the syringe 1 port. When the main body 314 is inserted into the syringe 1, the end of the limiting block 315 near the main body 314 overlaps the second end face 11 of the syringe 1 near the handle 2, thereby forming a limiting stop for the axial movement of the first connecting member 31, preventing it from being excessively displaced into the depth of the syringe 1 due to external force or internal pressure, thereby determining the reference installation position of the first connecting member 31 in the syringe 1.

[0049] Furthermore, the handle 2, as an external operating component, has its end near the syringe 1 at least partially inserted into the first mounting hole 311. The portion of the handle outside the syringe 1 abuts against the end of the limiting block 315 away from the second end face 11, thus cooperating with the syringe 1 to axially constrain the first connecting member 31. Simultaneously, the first connecting member 31 restricts the handle 2 from excessively displacing into the syringe 1, achieving relative positioning of the handle 2, the first connecting member 31, and the syringe 1. This configuration limits the first connecting member 31 to a preset axial working position, ensuring the accuracy of its relative position with the second connecting member 32, the syringe 1, and the handle 2, and the stability of the overall structure during operation. This makes the multiple components of the temperature probe 100 easy to assemble and clearly positioned relative to each other, and effectively transmits axial operating pressure, thereby ensuring the reliability and assembly accuracy of the device. To increase the connection stability between the first connector 31 and the syringe 1, multiple annular ribs can be provided on the outer wall of the body 314. The multiple annular ribs are spaced apart along the axial direction of the temperature probe 100 to increase the friction between the first connector 31 and the syringe 1, thereby improving their connection stability.

[0050] See Figure 2 , Figure 5In one embodiment, the outer diameter of the limiting block 315 is larger than the outer diameter of the body 314, so that a first limiting step 316 is formed between the body 314 and the limiting block 315, and the second end face 11 abuts against the first limiting step 316; a protrusion 3151 is provided at one end of the limiting block 315 near the second end face 11, and a limiting groove 111 is formed on the second end face 11 to cooperate with the protrusion 3151, and the protrusion 3151 is inserted into the limiting groove 111. The difference in outer diameter between the limiting block 315 and the body 314 and the end face cooperation structure can realize the axial positioning of the first connecting member 31 at the port of the syringe 1. During assembly, the second end face 11 of the syringe 1 near the handle 2 abuts against the first limiting step 316, which can prevent the first connecting member 31 from moving further into the syringe 1 when subjected to force or operation, and determine its axial installation depth in the syringe 1, thus forming axial positioning. To further constrain the circumferential freedom of the first connector 31 and ensure its assembly angle, a protrusion 3151 is provided at the end of the limiting block 315 near the second end face 11. Simultaneously, a corresponding limiting groove 111 with matching shape and size is machined on the second end face 11 of the syringe 1. During assembly, the protrusion 3151 must be aligned and inserted into the limiting groove 111 to achieve circumferential positioning and anti-rotation locking of the first connector 31. The cooperation between the protrusion 3151 and the limiting groove 111, combined with the axial abutment of the first limiting step 316, jointly achieves the connection limitation of the first connector 31 at the syringe 1 port, thereby achieving a stable connection of the connecting assembly 3 and allowing the housing of the temperature probe 100 to be repeatedly assembled.

[0051] Please see Figures 8 to 13 In one embodiment, the second connector 32 has a second mounting hole 324 for inserting the handle 2. The handle 2 includes a first connecting portion 21, a second connecting portion 22 and a third connecting portion 23 arranged sequentially along the axial direction of the syringe 1. The first connecting portion 21 is located at one end of the handle 2 near the syringe 1. The first connecting portion 21 and the second connecting portion 22 are rotatably disposed in the first mounting hole 311. At least a portion of the first connecting portion 21 is inserted into the second mounting hole 324. The first connecting portion 21 is threadedly connected to the inner wall of the second mounting hole 324. The third connecting portion 23 overlaps the end face of the first connector 31 near the handle 2.

[0052] In this embodiment, the connection structure between the second connector 32 and the handle 2 enables axial position adjustment of the second connector 32, allowing the operator to move the second connector 32 to the desired position as needed, thereby adjusting the tightness of the first connector 31 to achieve a preset seal between the first connector 31 and the syringe 1. The first connecting part 21 is located at the end of the handle 2 near the syringe 1, and its outer surface is machined with external threads, enabling thread engagement with the second connector 32 to drive the second connector 32 to perform axial displacement adjustment through rotation. The second connecting part 22 is located between the first connecting part 21 and the third connecting part 23, and is configured as a smooth cylindrical structure. The third connecting part 23 is located at the end of the handle 2 away from the syringe 1, and the operator rotates the handle 2 through the third connecting part 23. The second mounting hole 324 of the second connector 32 is configured as a through hole, and its inner wall is machined with internal threads that mate with the external threads of the first connecting part 21 of the handle 2, forming a threaded transmission pair. During operation, rotating the handle 2 causes the first connecting part 21 to rotate within the second mounting hole 324. The second connecting piece 32 is restricted from rotation by its engagement with the first connecting piece 31, thereby allowing relative movement between the external thread of the first connecting part 21 and the internal thread of the second connecting piece 32. The handle 2 is axially constrained by the overlapping structure of the third connecting part 23 and the end face of the first connecting piece 31. The threaded pair converts the rotational motion into axial linear movement of the second connecting piece 32 relative to the handle 2 and the first connecting piece 31, thereby causing the second connecting piece 32 to move towards the handle 2, gradually squeezing the first connecting piece 31 and causing the first connecting piece 31 to expand and tighten the gap between itself and the inner wall of the syringe 1, achieving a sealed assembly between the handle 2, the connecting assembly 3, and the syringe 1. This ensures the stability of the entire transmission structure in both the radial and axial directions, making the connection structure both adjustable and convenient to operate, and structurally reliable.

[0053] See Figure 2 In one embodiment, the temperature probe 100 further includes a waterproof component 4, which is sleeved around the first connecting portion 21 and located between the second connecting portion 22 and the second connecting member 32. The waterproof component 4 is used to seal the first connecting member 31 to the handle 2; and / or, the outer diameter of the second connecting portion 22 is larger than the outer diameter of the first connecting portion 21 so that a second limiting step 24 is formed between the second connecting portion 22 and the first connecting portion 21, and the waterproof component 4 elastically abuts against the second limiting step 24 and the second connecting member 32.

[0054] In this embodiment, the waterproof component 4 is sleeved on the end of the first connecting part 21 near the second connecting part 22, and axially constrained between the end face of the second connecting part 22 of the handle 2 and the corresponding end face of the second connecting member 32, thereby sealing the flow path between the handle 2 and the second connecting member 32. The waterproof component 4 can be made of an elastic material with resilience and high-temperature oil fume resistance, and its cross-section can be designed as annular to adapt to specific space and pressure requirements. When the handle 2 is assembled and locked, the waterproof component 4 is compressed axially by the second connecting part 22 and the second connecting member 32, and simultaneously squeezed radially by the outer surface of the first connecting part 21 and the inner wall of the first mounting hole 311, thereby filling the gaps between all mating surfaces, effectively blocking the path of high-temperature oil fumes or water vapor leakage along this axial interface, and improving the environmental adaptability and service life of the product.

[0055] In this embodiment, the second connecting portion 22 of the handle 2 has an outer diameter larger than that of the first connecting portion 21, thereby forming a second limiting step 24 at the shoulder where the two meet. The second limiting step 24 forms an annular bearing surface on the radial plane, providing an axial positioning reference for the installation of the waterproof component 4. The waterproof component 4 is fitted over the first connecting portion 21, with its end face near the third connecting portion 23 abutting against the second limiting step 24; at the same time, its opposite end face contacts the corresponding end face on the second connecting component 32. The waterproof component 4 is axially constrained by both the second limiting step 24 and the second connecting component 32, resulting in appropriate elastic compression, ensuring that the waterproof component 4 does not move axially in the working position. It also seals the annular gap between the outer periphery of the first connecting portion 21 and the inner hole of the second connecting component 32 through elastic deformation, effectively preventing liquid from penetrating along this interface.

[0056] See Figure 2 , Figure 5In one embodiment, the inner wall of the first mounting hole 311 is provided with a first limiting portion 3111, and the outer wall of the second connecting member 32 is provided with a second limiting portion 325 that cooperates with the first limiting portion 3111. The first limiting portion 3111 and the second limiting portion 325 cooperate to restrict relative rotation between the second connecting member 32 and the first connecting member 31. To prevent relative rotation between the second connecting member 32 and the first connecting member 31 during assembly and to ensure that the handle 2 can drive the second connecting member 32 to move axially when rotated, a first limiting portion 3111 and a second limiting portion 325 that cooperate with each other are provided between the first connecting member 31 and the second connecting member 32. The first limiting portion 3111 may be a groove, keyway, or plane extending axially, while the second limiting portion 325 may be a convex key, guide rail, or corresponding plane that cooperates with the first limiting portion 3111. When the second connector 32 is inserted into the first mounting hole 311, the second limiting part 325 on its outer wall can be aligned with and embedded or fitted with the first limiting part 3111 on the inner wall of the hole, so that an effective circumferential limiting is formed between the two. This allows the second connector 32 to move linearly along the axial direction of the temperature probe 100 within the first mounting hole 311, thus restricting its rotational movement around the axis. During assembly, only the handle 2 needs to be turned to achieve the connection, assembly and sealing of the temperature probe 100 housing, thereby improving the assembly efficiency of the temperature probe 100 and reducing the assembly difficulty of the temperature probe 100.

[0057] See Figures 5 to 7 In one embodiment, the first limiting part 3111 is provided with a first limiting surface 3111a, and the second limiting part 325 is provided with a second limiting surface 325a that cooperates with the first limiting surface 3111a. The first limiting surface 3111a is used to cooperate and abut with the second limiting surface 325a; and / or, the first limiting part 3111 is provided with a positioning bone 3111b, and the second limiting part 325 is provided with a positioning groove 325b that cooperates with the positioning bone 3111b. The positioning bone 3111b is inserted into the positioning groove 325b.

[0058] See Figure 5 In one embodiment, the first limiting part 3111 and the second limiting part 325 adopt a surface contact limiting method. That is, a first limiting surface 3111a is machined on the first limiting part 3111, and a corresponding second limiting surface 325a parallel to it is provided on the second limiting part 325. When the two are assembled in place, the two surfaces fit tightly together and abut against each other, resisting circumferential torque through large-area contact. Among them, multiple first limiting surfaces 3111a can be arranged sequentially along the circumference of the temperature probe 100, and multiple second limiting surfaces 325a that cooperate with the first limiting surfaces 3111a are correspondingly arranged along the circumference. That is, the cross-sectional shape of the second connector 32 is set as a polygon, and the cross-section of the first mounting hole 311 is set as a polygon that cooperates with the cross-section of the second connector 32, thereby further improving the connection stability between the first connector 31 and the second connector 32.

[0059] See Figure 6 , Figure 7 In another embodiment, the first limiting part 3111 and the second limiting part 325 are configured as a concave-convex interlocking limiting mechanism. The first limiting part 3111 has a protruding positioning rib 3111b, such as a guide rib or key, while the second limiting part 325 has a matching positioning groove 325b. Mechanical interlocking is achieved by inserting the positioning rib 3111b into the positioning groove 325b, thereby restricting the relative circumferential movement of the first connecting member 31 and the second connecting member 32. Both structures can be used independently or in combination to provide redundancy, ensuring that the second connecting member 32 maintains a preset circumferential orientation during axial movement. This ensures that the second connecting member 32 can transmit axial force to the first connecting member 31, effectively avoiding defects such as uneven sealing or component wear caused by torsion, and improving the reliability of the transmission and sealing system.

[0060] See Figure 2 , Figure 10 In one embodiment, the temperature probe 100 further includes a temperature measuring component 5 and a first elastic member 6 disposed within the syringe 1. A slot 25 is formed at one end of the handle 2 near the syringe 1, and at least a portion of the temperature measuring component 5 is inserted into the slot 25. The first elastic member 6 elastically abuts against the end of the temperature measuring component 5 away from the handle 2. Alternatively, the temperature probe 100 further includes a temperature measuring component 5, a second elastic member 7, and a support member 8 disposed within the syringe 1. A slot 25 is formed at one end of the handle 2 near the syringe 1, and at least a portion of the temperature measuring component 5 is inserted into the slot 25. The second elastic member 7 is installed in the slot 25 and elastically abuts against the temperature sensing element and the bottom wall of the slot 25. The support member 8 abuts against the end of the temperature measuring component 5 away from the handle 2.

[0061] Please see Figure 12In one embodiment, the temperature measuring component 5 includes a power supply, a circuit board, and a thermocouple, which are sequentially arranged and interconnected along the axial direction of the temperature probe 100. The power supply is located at the end of the circuit board away from the handle 2, and the thermocouple is located at the end of the circuit board closer to the handle 2. A slot 25 is provided at the end of the handle 2 near the syringe 1, and the end of the thermocouple away from the power supply is inserted into the slot 25 to achieve electrical and mechanical connection. The first elastic element 6 is configured as a spring and is located at the far end of the temperature measuring component 5 away from the handle 2 to elastically abut against the battery, thereby providing axial elastic preload or buffer for the temperature measuring component 5 and ensuring that its measuring end maintains a stable contact state during operation. In this embodiment, the elastic element is located at the tip of the temperature probe 100, and the tip is inserted into the food during use without contacting high-temperature fumes and steam. Therefore, the elastic element does not need to be made of a high-temperature resistant material; it only needs to be able to withstand the temperature of the food during cooking. In this case, the first elastic element 6 has a larger volume, which can buffer greater mechanical stress. At the same time, the material cost of the first elastic element 6 is lower.

[0062] Please see Figure 2 , Figure 8 In another embodiment, the temperature probe 100 further includes a temperature measuring component 5, a second elastic element 7, and a support element 8. The temperature measuring component 5 is partially inserted into a slot 25 at the end of the handle 2. The second elastic element 7 is installed inside the slot 25 and elastically abuts against the proximal end of the temperature measuring component 5 and the bottom wall of the slot 25, thereby providing elastic support to the temperature measuring component 5. The support element 8 is located at the end of the temperature measuring component 5 near the battery and abuts against the inner wall of the battery and the syringe 1, thereby supporting the temperature measuring component 5. In this embodiment, the elastic element is located at the part of the temperature probe 100 near the handle 2. During use, the handle 2 part will not be inserted into food, so it will come into contact with high-temperature fumes and steam. At this time, the elastic element needs to be supported by a high-temperature resistant material so that it can withstand the high-temperature conditions generated by the fumes. At this point, because the support member 8 can stably abut against the battery of the temperature sensing component 5 through surface-to-surface contact, the thermocouple of the temperature sensing component 5 can be inserted into the slot 25 and supported and limited by the slot wall of the slot 25. Therefore, under the premise of stress buffering protection, the shaking of the temperature sensing component 5 can be reduced, making it less likely to deviate from its original installation position when buffering axial stress. The elastic element in the temperature probe can provide pressure buffering protection for the internally installed temperature sensing component 5, optimize its thermal contact conditions, and buffer external mechanical stress, thereby ensuring stable transmission of the temperature measurement signal.
