Description

Technical Field

[0001] The present invention relates to the technical field of temperature probes, and in particular to a temperature probe. Background Art

[0002] The ceramic handle used in existing temperature probes usually contains two glue points, which can completely seal the internal cavity of the ceramic handle in the product, thereby ensuring that the product meets waterproof standards.

[0003] Generally, the glues used are divided into two categories: one is cured by absorbing moisture in the air, that is, it needs to come into contact with air to achieve the curing process; the other type needs to be baked and cured by heating.

[0004] For products like temperature probes, which are completely enclosed and have a small space, using glue that requires moisture to cure will take a long time to complete because the internal environment is difficult to contact with the outside air, and thus cannot perform its intended bonding and sealing functions. If the glue is cured by heating and baking, the air inside the needle of the temperature probe will expand due to the heat during the baking process. The expanding air will squeeze the uncured glue out of the glue dispensing area, causing the glue to overflow and solidify to form pores, which in turn affects the waterproof performance of the temperature probe. Therefore, during the manufacturing process of existing temperature probes, it is not easy to seal the connection between the ceramic handle, the needle body, and the sealing component.

[0032] The ceramic handle used in existing temperature probes usually contains two glue points, which can completely seal the internal cavity of the ceramic handle in the product, thereby ensuring that the product meets waterproof standards.

[0033] Generally, the glues used are divided into two categories: one is cured by absorbing moisture in the air, that is, it needs to come into contact with air to achieve the curing process; the other type needs to be baked and cured by heating.

[0034] For products like temperature probes, which are completely enclosed and have a small space, using glue that requires moisture to cure will take a long time to complete because the internal environment is difficult to contact with the outside air, and thus cannot perform its intended bonding and sealing functions. If the glue is cured by heating and baking, the air inside the needle of the temperature probe will expand due to the heat during the baking process. The expanding air will squeeze the uncured glue out of the glue dispensing area, causing the glue to overflow and solidify to form pores, which in turn affects the waterproof performance of the temperature probe. Therefore, during the manufacturing process of existing temperature probes, it is not easy to seal the connection between the ceramic handle, the needle body, and the sealing component.

[0035] The present invention provides a temperature probe 100 .

[0036] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , in one embodiment of the present invention, the temperature probe 100 includes a needle body 1;

[0037] A handle 2 having a first port 21 and a second port 22, and a gas passage 23 communicating with the first port 21 and the second port 22. The handle 2 is sleeved on the outside of the needle body 1 via the first port 21, and a first dispensing position 24 is formed between the handle 2 and the needle body 1; and

[0038] A sealing assembly 3, comprising an air guide 31 and a sealing cover 32. The air guide 31 is inserted into the handle 2 via the second port 22. A second glue dispensing position 33 is formed between the air guide 31 and the sealing cover 32. The air guide 31 has an air vent 311 for connecting the gas channel 23 with the outside world. The sealing cover 32 is used to seal the air vent 311 after the glue at the first glue dispensing position 24 and the second glue dispensing position 33 is cured.

[0039] In this embodiment, the handle 2 may have a first port 21 and a second port 22 at either end along its axial direction, as well as a gas channel 23 connecting the first port 21 and the second port 22. The gas channel 23 may extend along the axial direction of the handle 2. By configuring the handle 2 to be sleeved onto the needle body 1 via the first port 21, a first glue dispensing position 24 is formed between the handle 2 and the needle body 1. The first glue dispensing position 24 is used to fill the handle 2 with glue, thereby sealing the handle 2 to the end of the needle body 1 away from the needle tip during the glue dispensing process. Specifically, the glue may be a glue that solidifies by absorbing moisture from the air, or a glue that solidifies by heating.

[0040] In this embodiment, to enhance the waterproof performance of the present invention, a sealing assembly 3 is hermetically connected to the second port 22. This prevents water vapor from invading the temperature probe 100 during cooking, potentially damaging the internal electronic components and extending the service life of the temperature probe 100. The sealing assembly 3 may include an air guide 31 and a sealing cap 32. The air guide 31 is inserted into the handle 2 via the second port 22, and a second glue dispensing area 33 is formed between the air guide 31 and the sealing cap 32. The second glue dispensing area 33 is used to fill the second glue dispensing area 33 with a colloid. The sealing cap 32 is hermetically connected to the air guide 31 through a glue dispensing process, thereby sealing the second port 22 and securing the air guide 31 within the second port 22, thereby enhancing the airtightness of the present invention. The colloid may also be a glue that solidifies by absorbing moisture from the air, or a glue that solidifies by heating. The air guide 31 has an air vent 311 connecting the gas channel 23 with the outside world, so that the high-temperature expanded gas in the gas channel 23 can be discharged to the outside world through the gas channel 23 and the air vent 311, or the outside air can be transported into the handle 2 through the air vent 311 and the gas channel 23, so that the colloid can absorb moisture and solidify.

[0041] In this embodiment, taking the example of a glue that is heated and cured at the first glue point 24, during the heating process of the present application, the gas inside the gas channel 23 is heated to form a high-temperature expanded gas, and the high-temperature expanded gas can be transported to the external environment through the gas channel 23 and the vent 311, thereby preventing the high-temperature expanded gas from squeezing the uncured colloid out of the first glue point 24, thereby preventing the colloid from overflowing and curing to form pores, and further avoiding the influence of high-temperature gas on the waterproof performance of the present application during the production process.

[0042] In this embodiment, taking the colloid at the first glue point 24 and the colloid at the second glue point 33 as an example, while the present application is stationary and waiting for the colloid to solidify, air from the external environment enters the handle 2 and the needle body 1 through the vent 311 and the gas channel 23, so that the air directly contacts the colloid at the first glue point 24 and the second glue point 33, thereby enabling the colloid at the two glue points to solidify quickly, thereby avoiding the situation where the colloid cannot be completely solidified for a long time due to difficulty in contact with the outside air, so that the colloid can normally play its bonding and sealing role. Specifically, the colloid at the second glue point 33 can directly contact the outside air through the second port 22, and the amount of colloid at the first glue point 24 is greater than the amount of colloid at the second glue point 33. Therefore, the colloid can be first filled in the first glue dispensing position 24, and wait for the colloid to be cured after contacting with the air, and then the colloid can be filled in the second glue dispensing position 33, and wait for the colloid in the second glue dispensing position 33 to fully absorb moisture but not yet completely cured, and then the sealing cover 32 can be assembled to the air guide 31 so that the sealing cover 32 is sealed and connected to the vent hole 311 through the colloid.

[0043] The technical solution of the present invention is to adopt a handle 2 with a first port 21, a second port 22 and a gas channel 23 connecting the first port 21 and the second port 22, and the air guide 31 has an air vent 311 connecting the gas channel 23 with the outside world; when the needle body 1 and the handle 2 are in a heated and baking state, the expanded air inside the two can be discharged to the outside world through the gas channel 23 and the air vent 311, thereby avoiding the situation where the colloid overflows and solidifies to form air holes; or, the outside air can contact the moisture-curing colloid through the air vent 311 and the gas channel 23, so that the colloid absorbs moisture in the air and solidifies quickly, thereby solving the problem of inconvenient sealing connection between the existing handle 2 and the needle body 1 and the sealing component 3.

[0044] like Figure 2 and Figure 4 As shown, in this embodiment, the sealing cover 32 includes a cover body 321 accommodated in the second port 22, and a first protrusion 322 provided on one side of the cover body 321, the first protrusion 322 is inserted into the vent hole 311, and the first protrusion 322 is gap-fitted with the inner wall surface of the vent hole 311.

[0045] In this embodiment, the first protrusion 322 and the vent hole 311 can be plugged together, thereby improving the stability of the connection between the sealing cover 32 and the air guide 31. The sealing cover 32 is sealed to the air guide 31 and the second port 22 of the handle 2 through the glue at the second glue dispensing station 33, so that the first protrusion 322 and the inner wall surface of the vent hole 311 can be assembled in a clearance fit, thereby simplifying the production process of the sealing cover 32 and the air guide 31, thereby improving the production efficiency of the present application.

[0046] In this embodiment, the colloid is a moisture-curing colloid. The first dispensing station 24 and the second dispensing station 33 can both use moisture-curing colloid, thereby avoiding the need for additional heating equipment for heating and baking. The colloid can be cured by simply standing on the equipment, thereby simplifying the production process of this application.

[0047] In this embodiment, different glues can be used for the first glue dispensing station 24 and the second glue dispensing station 33 according to production requirements. The first glue dispensing station 24 can use a heat-curing glue, while the second glue dispensing station 33 can use a moisture-curing glue, thereby increasing the scope of application of the present invention and enabling the present invention to meet the different needs of more production plants.

[0048] like Figure 2 、 Figure 3 and Figure 5 As shown, in this embodiment, the air guide 31 includes a main body 312 accommodated in the second port 22, and a second protrusion 313 provided on the side of the main body 312 close to the cover body 321, the second protrusion 313 has the vent hole 311, and the end surface of the cover body 321 close to the main body has a first groove 323, and the second protrusion 313 is inserted into the first groove 323.

[0049] In this embodiment, the central axis of the vent 311 can be coaxially arranged with the central axis of the gas channel 23 to facilitate the flow of gas within the gas channel 23 to the external environment through the vent 311, or to facilitate the flow of air from the external environment into the gas channel 23 through the vent 311. To further enhance the stability of the connection between the air guide 31 and the sealing cover 32, a second protrusion 313 is provided to engage with the first groove 323 in a plug-in manner. A second glue dispensing station 33 is formed between the outer peripheral wall of the second protrusion 313 and the inner sidewall of the first groove 323 to seal the outer peripheral wall of the second protrusion 313 and the inner sidewall of the first groove 323 through a glue dispensing process, thereby enhancing the airtightness between the air guide 31 and the sealing cover 32.

[0050] like Figure 3 and Figure 4 As shown, in this embodiment, the air guide 31 further includes a connecting section 314 provided on the side of the body 312 close to the handle 2 , and the outer wall surface of the connecting section 314 is sealed to the inner wall surface of the second port 22 via a sealing structure.

[0051] In this embodiment, the connecting section 314 is used to be sealed to the inner wall surface of the second port 22 via a sealing structure. The connecting section 314 can extend along the axial direction of the air guide 31, thereby further increasing the contact area between the air guide 31 and the second port 22, thereby improving the stability of the sealed connection between the air guide 31 and the second port 22. The sealing structure can be an elastic material such as colloid or elastic silicone to enhance the sealing performance between the air guide 31 and the inner circumferential wall of the second port 22.

[0052] like Figure 2 As shown, in this embodiment, a plurality of third protrusions 3141 are protruded from the outer peripheral wall of the connecting section 314, and the plurality of third protrusions 3141 are arranged at intervals along the axial direction of the connecting section 314, and a second groove 3142 is formed between any adjacent third protrusions 3141, and a third glue dispensing position 25 is formed between the inner wall surface of the second groove 3142 and the inner wall surface of the second port 22, and the third glue dispensing position 25 is filled with moisture-curing colloid to form the sealing structure.

[0053] In this embodiment, the plurality of third protrusions 3141 are configured to abut the inner circumferential wall of the second port 22, thereby improving the stability of the connection between the connecting section 314 and the inner circumferential wall of the second port 22. The inner wall surface of the second groove 3142 is configured to form a third glue dispensing location 25 with the inner circumferential wall of the second port 22. The third glue dispensing location 25 is filled with a moisture-curable glue to form a sealing structure, thereby sealing the inner wall surface of the second groove 3142 with the inner circumferential wall of the second port 22 through the glue. This improves the stability of the connection between the connecting section 314 and the inner circumferential wall of the second port 22, thereby enhancing the sealing performance between the air guide 31 and the inner circumferential wall of the second port 22.

[0054] like Figure 3 and Figure 6 As shown, in this embodiment, the air guide 31 also includes an abutment section 315 provided on the side of the main body 312 close to the cover body 321, and the abutment section 315 is located between the connecting section 314 and the second protrusion 313, and the second port 22 includes a first mounting section 221 and a second mounting section 222 that are interconnected, and the outer diameter of the second mounting section 222 is larger than the outer diameter of the first mounting section 221, and the second mounting section 222 is located at one end of the first mounting section 221 close to the sealing cover 32, and the connecting section 314 is inserted into the first mounting section 221 via the second mounting section 222, and the abutment section 315 abuts against the inner side wall of the second mounting section 222.

[0055] In this embodiment, the abutting section 315 is used to abut the inner sidewall of the second mounting section 222, thereby facilitating the assembly of the air guide 31 into the second port 22 and limiting the displacement of the air guide 31 in the direction approaching the needle body 1. By setting the outer diameter of the second mounting section 222 to be larger than the outer diameter of the first mounting section 221, a cross-section of the second port 22 along its central axis is formed into a stepped shape. The outer diameter of the first mounting section 221 is smaller than the outer diameter of the abutting section 315, thereby facilitating the abutment of the inner sidewall of the second mounting section 222, thereby improving the stability of the connection between the air guide 31 and the second port 22.

[0056] In this embodiment, a second glue dispensing position 33 can be formed between the outer peripheral wall of the abutting section 315 and the connecting end surface of the sealing cover 32 close to the first protrusion 322, so that the outer peripheral wall of the abutting section 315 and the connecting end surface of the sealing cover 32 are sealed and connected through the glue dispensing process, thereby improving the air tightness between the air guide 31 and the sealing cover 32.

[0057] like Figure 3 As shown, in this embodiment, the temperature probe 100 also includes an antenna, which includes an antenna body 4 and a spiral portion 41 provided at one end of the antenna body 4. The antenna body 4 is provided in the needle body 1, the handle 2 and the air guide 31. The connecting section 314 has an accommodating cavity 3143 with one end open, and the inner wall of the accommodating cavity 3143 has an installation groove 3144, and the spiral portion 41 is installed in the installation groove 3144.

[0058] In this embodiment, the connecting section 314 is provided with a accommodating cavity 3143 with an open end, and the inner wall of the accommodating cavity 3143 has a mounting groove 3144 for mounting the spiral portion 41 on the antenna body 4. The mounting groove 3144 can be arranged in a spiral shape along the axial direction of the connecting section 314, so that the mounting groove 3144 matches the shape of the spiral portion 41, thereby improving the stability of the installation of the spiral portion 41 and the mounting groove 3144.

[0059] In this embodiment, the temperature probe 100 further includes a control module disposed within the needle body 1. The control module includes a circuit board, a connector, and a battery. The connector can be configured as a metal member such as a spring for conducting electricity. The circuit board is electrically connected to the battery. The circuit board is connected to the needle body 1 via the connector so that the needle body 1 forms a first electrode, which can be a negative electrode. The end of the antenna body 4 away from the spiral portion 41 is connected to the circuit board so that the sealing assembly 3 forms a second electrode, which can be a positive electrode, thereby facilitating battery charging. It should be noted that the circuit board, connector, and battery are not labeled in the drawings in the specification.

[0060] like Figure 3 and Figure 6As shown, in this embodiment, the inner wall of the first port 21 is protruded with a plug-in portion 211, and the first glue dispensing position 24 is provided between the outer wall of the plug-in portion 211 and the inner wall of the first port 21. The needle body 1 is inserted in the first glue dispensing position 24, and the outer wall of the needle body 1 is sealed and connected to the inner wall of the first port 21 through the glue.

[0061] In this embodiment, the outer diameter of the plug portion 211 gradually increases from the first port 21 toward the second port 22, so that the needle body 1 is gradually squeezed when inserted into the first glue point 24 between the plug portion 211 and the inner wall of the first port 21, thereby more firmly fixing the needle body 1 to the first glue point 24. At the same time, the outer wall of the needle body 1 and the inner wall of the first port 21 are sealed by the glue, thereby improving the waterproof performance.

[0062] In this embodiment, the needle body 1 and / or the sealing assembly 3 are metal parts made of metal materials, and the handle 2 is a ceramic part made of ceramic materials.

[0063] In this embodiment, needle body 1 and / or sealing assembly 3 are constructed of metal, which exhibits high strength, high temperature and pressure resistance, excellent thermal conductivity, corrosion resistance, and wear resistance, thereby ensuring the stability and long service life of needle body 1 and sealing assembly 3. The ceramic handle 2, on the other hand, exhibits high temperature resistance, insulation, low thermal conductivity, and chemical corrosion resistance, thereby enhancing the safety and operational comfort of handle 2 and extending the service life of temperature probe 100.

[0064] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention.
