DETAILED DESCRIPTION

[0042] The following is combined with Figures 1 to 20 This application is described in further detail.

[0043] Reference Figure 1 and Figure 2 The embodiment of the present application discloses a thermometer with a detachable wireless temperature probe, including a body 1 and a wireless temperature probe 2. The body 1 and the wireless temperature probe 2 communicate through wireless signals. The display screen 14 on the body 1 can display temperature data. These are all existing technologies. The wireless temperature probe 2 can also communicate with a mobile phone and obtain temperature display through a mobile phone APP, that is, the wireless temperature probe 2 is independent and can be used in combination with the body 1 or alone.

[0044] Reference Figure 4 and Figure 5 The thermometer also includes a rotating disk 3, which is rotatably arranged on the body 1, and a socket seat 31 is provided on the rotating disk 3. The wireless temperature probe 2 can be detachably plugged into the socket seat 31; a semi-open storage bin 11 is provided on the side of the body 1, and the wireless temperature probe 2 can be stored in the storage bin 11 after rotation. The body 1 has a first circuit board 12 and a first rechargeable battery 13 built in. The first rechargeable battery 13 is electrically connected to the first circuit board 12, and the first rechargeable battery 13 is used to supply power to the body 1.

[0045] Reference Fig.13 and Fig.16 The wireless temperature probe 2 includes a needle tube 21, a ceramic handle 22, a metal tail cover 23, a second circuit board 24 and a second rechargeable battery 25, and the second rechargeable battery 25 is used to power the wireless temperature probe 2; the second circuit board 24 and the second rechargeable battery 25 are both arranged in the accommodating cavity of the needle tube 21 and the ceramic handle 22, the needle tube 21, the metal tail cover 23 and the second rechargeable battery 25 are all electrically connected to the second circuit board 24, and the needle tube 21 and the metal tail cover 23 are respectively used as the positive and negative poles for charging the wireless temperature probe 2; a first charging contact 32 is provided at the bottom of the socket seat 31, which is used to electrically connect with the metal tail cover 23 when the wireless temperature probe 2 is plugged into the socket seat 31, and a second charging contact 15 is provided on the side wall of the storage bin 11, which is used to electrically connect with the outer wall of the needle tube 21 when the wireless temperature probe 2 is stored in the storage bin 11; the first charging contact 32 and the second charging contact 15 are both electrically connected to the first circuit board 12, and are used to charge the wireless temperature probe 2.

[0046] Reference Figures 8 to 10The metal tail cover 23 (which can also be a ceramic handle) has an annular groove 231 on its side, and an elastic card block 33 is provided on the inner wall of the socket seat 31. When the wireless temperature probe 2 is plugged into the socket seat 31, the elastic card block 33 is inserted into the annular groove 231. When the wireless temperature probe 2 is plugged in, it will push the elastic card block 33 back. When it is plugged in, the elastic card block 33 will extend forward and be inserted into the annular groove 231. The wireless temperature probe 2 is stuck and locked, and cannot be removed by itself. It is reliably fixed. When the user pulls it out with a little force, it can be unlocked, and it is very convenient to disassemble and assemble.

[0047] The body 1 and the wireless temperature probe 2 of the thermometer of the present application adopt a split design, which can be detachably plugged in and communicate through wireless signals. The wireless temperature probe 2 can be directly installed on the body 1 and used as a handheld thermometer, and can also be used separately without being restricted by the usage scenario, thus realizing a two-in-one function; the rotating disk 3 is rotatably arranged on the body 1, and the wireless temperature probe 2 can be unfolded for use and folded for storage in the storage bin 11. The storage bin 11 can play a protective role to prevent the wireless temperature probe 2 from accidental damage. After storage, the overall length of the thermometer becomes shorter, which is convenient for placement.

[0048] Reference Figures 5 to 7 The body 1 includes a panel 16, a frame 17, an upper shell 18 and a lower shell 19, the upper shell 18 and the lower shell 19 are fixed by screws, the frame 17 is arranged on the upper shell 18, and the panel 16 is arranged on the frame 17; a display screen 14 is arranged on the front of the first circuit board 12, and a first avoidance hole 181 is arranged at a corresponding position of the upper shell 18 for exposing the display screen 14; the first rechargeable battery 13 is located on the back of the first circuit board 12.

[0049] Reference Figure 7 The rear of the body 1 is provided with an infrared temperature measurement module 4, and the upper shell 18 is provided with a fourth avoidance hole 184 at a corresponding position for exposing the infrared temperature measurement module 4. Existing probe-type thermometers cannot be inserted into hard foods (such as frozen foods) and cannot measure the internal temperature of such foods. The infrared temperature measurement module 4 is integrated on the body 1 of the present application, and can measure the surface temperature of some hard foods that the temperature probe cannot be inserted into, thereby increasing the use scenarios of the thermometer.

[0050] Reference Figure 6 and Figure 7 The first circuit board 12 is provided with a charging port 121 and a function button 122 on the side thereof, and the upper shell 18 is provided with a second avoidance hole 182 and a third avoidance hole 183 at corresponding positions, respectively used to expose the charging port 121 and the function button 122. In this embodiment, the charging port 121 is a TYPE-C charging port 121, and the function button 122 can be an on / off key, an infrared temperature measurement key, etc.

[0051] Reference Figure 4 , Figure 6 and Figure 7 A first annular sealing ring 5 is provided between the upper shell 18 and the lower shell 19, a second annular sealing ring 6 is provided between the rotating disk 3 and the upper shell 18, and a third annular sealing ring 7 is provided between the rotating disk 3 and the lower shell 19. The fuselage body 1 is provided with many electronic components (such as circuit boards, display screens, batteries, etc.) inside, and is used in more complex environments such as kitchens and outdoors, and needs to achieve a certain waterproof level. The first annular sealing ring 5 is used to prevent water or moisture from entering between the upper shell 18 and the lower shell 19, the second annular sealing ring 6 is used to prevent water or moisture from entering between the rotating disk 3 and the upper shell 18, and the third annular sealing ring 7 is used to prevent water or moisture from entering between the rotating disk 3 and the lower shell 19, so as to ensure that the fuselage body 1 has good waterproof performance and improve the service life of the product.

[0052] Reference Fig.11 and Fig.12 The storage bin 11 is arranged on the side of the upper shell 18, and the two opposite side walls of the storage bin 11 are provided with positioning protrusions 111 for limiting the wireless temperature probe 2. Firstly, the wireless temperature probe 2 can be better limited to prevent the wireless temperature probe 2 from accidentally falling out, and secondly, the stability of the electrical connection between the second charging contact 15 and the outer wall of the needle tube 21 can be better ensured, thereby ensuring the charging effect; the upper shell 18 and the lower shell 19 are both provided with finger dialing holes 185 and 191 for people to reach in and dial the wireless temperature probe 2, which is convenient for users to operate.

[0053] Wireless temperature probes are used to measure the temperature of food and generally need to achieve a waterproof rating of at least IPX7. To achieve this waterproof rating, existing wireless temperature probes generally use sealing rings or snap-on seals to ensure waterproofing. Since the radial dimensions of wireless temperature probes are relatively small, there are technical problems such as high requirements for parts processing accuracy, complex sealing structures, high assembly difficulty, and a high defect rate.

[0054] Reference Figures 14 to 16 Both ends of the ceramic handle 22 are provided with external threads, the end face of the tail end of the needle tube 21 is provided with a screw groove 211, the screw groove 211 is provided with an internal thread, and the metal tail cover 23 is also provided with an internal thread. One end of the ceramic handle 22 is screwed to the tail end of the needle tube 21, and the other end is screwed to the metal tail cover 23, and waterproof sealant 26 is provided at the screw connection; the ends of the needle tube 21 and the metal tail cover 23 are provided with annular glue storage grooves 212 and 232.

[0055] Both ends of the ceramic handle 22 of the present application are sealed by means of threads and waterproof sealant 26, especially a threaded groove 211 is provided on the end face of the tail end of the needle tube 21 to form a "U"-shaped gap, and this "U"-shaped gap is completely filled with waterproof sealant 26 to achieve a good sealing and waterproof effect. The waterproof structure of the present application is simple in design, has low requirements on parts processing accuracy, has a good waterproof effect, simplifies the assembly process, reduces the defective rate, and reduces the manufacturing cost.

[0056] Since the amount of waterproof sealant 26 that can be accommodated at the threaded connection is small, it is easy to have voids and discontinuities, and the waterproof effect is not reliable enough. After the annular glue storage grooves 212 and 232 are provided, the waterproof sealant 26 here can form a complete and continuous ring with a larger cross-sectional area, which is not easy to produce voids and discontinuities, so the waterproof effect is better.

[0057] Reference Fig.16 The needle tube 21 includes a metal connecting tube 213 and a needle tube body 214. The head end of the metal connecting tube 213 is inserted into the needle tube body 214 and fixedly connected to the needle tube body 214 through a circumferential weld 215. The screw connection groove 211 and the internal thread are arranged on the metal connecting tube 213. The position of the circumferential weld 215 is at the safety line of the wireless temperature probe 2. The circumferential weld 215 is generally laser welded, which will leave a weld seam, which can be used as the safety line of the wireless temperature probe 2, eliminating the step of engraving the safety line later, and saving process costs.

[0058] Reference Fig.15 and Fig.18 The central aperture of the metal connecting tube 213 is consistent, and the wall thickness of the tail end gradually increases to process the screw groove 211 and the internal thread. The traditional needle tube 21 has a thin wall thickness, and it is impossible to process a structure such as the screw groove 211. Therefore, the present application splits the needle tube 21 into the metal connecting tube 213 and the needle tube body 214. The needle tube body 214 can still adopt a thin-walled tube structure. The metal connecting tube 213 makes full use of its own shape and adopts an uneven wall thickness structure. The tail end of the metal connecting tube 213 is thicker, so that the screw groove 211 and the internal thread can be more conveniently processed.

[0059] Reference Fig.14 and Fig.15 The tail end of the second circuit board 24 is also fixed with an internal connector 27, and the tail end of the internal connector 27 is provided with a flange edge 271. The diameter of the flange edge 271 is larger than the inner diameter of the ceramic handle 22. The flange edge 271 is located between the metal tail cover 23 and the ceramic handle 22 to limit the position of the second circuit board 24 in the ceramic handle 22 and the needle tube 21 to prevent the second circuit board 24 from axial movement; the internal connector 27 is electrically connected to the second circuit board 24 and the metal tail cover 23, and is also used as an intermediate conductive member.

[0060] Reference Fig.16 The second circuit board 24 is provided with a food temperature sensor, an ambient temperature sensor 242, an antenna and a V-shaped contact spring 241, and the second circuit board 24 is electrically connected to the needle tube 21 through the V-shaped contact spring 241. The second circuit board 24 of the present application is made into an integrated long strip board, and all electronic devices and antennas are integrated on this board. No other circuit connections are required, and the assembly process is simpler. The middle part of the V-shaped contact spring 241 is welded to the second circuit board 24. Due to its good elasticity, the elastic sheets on both sides are in elastic contact with the inner wall of the needle tube 21. This design is simple to assemble and has a good contact effect. Since the metal tail cover 23 and the needle tube 21 are both electrically connected to the second circuit board 24, they can be used as the positive and negative electrodes for charging the second rechargeable battery 25.

[0061] Reference Fig.19 and Fig. 20 , as another embodiment of the wireless temperature probe in the present application, it is different from the above embodiment in that an internal connector 27 is fixedly provided at the tail end of the second circuit board 24, and the internal connector 27 is electrically connected to the second circuit board 24 and the metal tail cover 23; the internal connector 27 includes a fixing tube 272, the ambient temperature sensor 242 is arranged in the fixing tube 272, and a thermal conductive glue is also provided between the fixing tube 272 and the ambient temperature sensor 242, a protrusion 2721 is provided at the tail end of the fixing tube 272, and a through hole 233 is provided at the corresponding position of the metal tail cover 23, and the protrusion 2721 is embedded in the through hole 233 and exposes the surface of the metal tail cover 23 to better sense the ambient temperature.

[0062] In this embodiment, since the protrusion 2721 on the fixed cylinder 272 exposes the surface of the metal tail cover 23, and a thermal conductive adhesive is provided between the fixed cylinder 272 and the ambient temperature sensor 242, the metal tail cover 23 and the internal connecting piece 27 are both metals with excellent thermal conductivity. The temperature of the fixed cylinder 272 can better reflect the ambient temperature, so the ambient temperature sensor 242 can better sense the ambient temperature.

[0063] Reference Fig.19 The protrusion 2721 and the metal tail cover 23 are fixed and sealed by welding; a metal ring wall 234 is also provided inside the metal tail cover 23, and the fixed cylinder 272 is in contact with the inner wall of the metal ring wall 234 (or a heat-conducting adhesive is provided between the fixed cylinder 272 and the metal ring wall 234). Since the metal ring wall 234 inside the metal tail cover 23 is in contact with the fixed cylinder 272, the heat conduction performance between the metal tail cover 23 and the fixed cylinder 272 is better, and the temperature of the fixed cylinder 272 can better reflect the ambient temperature.

[0064] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
