[0036] The utility model provides a barbecue temperature probe, which can solve the problem of complicated assembly process of the existing barbecue temperature probe, so as to improve the assembly efficiency of the barbecue temperature probe during manufacturing.

[0037] Please refer to Figures 1 to 4In an embodiment of the barbecue temperature probe 10 proposed in the utility model, the barbecue temperature probe 10 includes a shell 100, a handle 200, a temperature measuring component 300 and a charging positive electrode 400, the shell 100 has a first accommodating cavity 110 with an opening at one end, and the shell 100 is made of a metal material; the handle 200 has a second accommodating cavity 210 with openings at both ends, and the handle 200 is made of an insulating material. The handle 200 is sleeved on the shell 100 and connected to the open end of the shell 100, and the second accommodating cavity 210 is connected to the first accommodating cavity 110; the temperature measuring component 300 includes a temperature measuring body 310 and a radio frequency antenna electrically connected to the temperature measuring body 310 320, at least part of the temperature measuring body 310 is arranged in the first accommodating cavity 110, at least part of the radio frequency antenna 320 is arranged in the second accommodating cavity 210, the temperature measuring body 310 is electrically connected to the shell 100, so that the shell 100 is suitable for being used as a charging negative electrode; the charging positive electrode 400 is arranged in the second accommodating cavity 210 and is located at the end of the handle 200 away from the shell 100, the charging positive electrode 400 is sealed and connected to the inner wall of the handle 200, and a groove 420 is provided on the charging positive electrode 400, and the radio frequency antenna 320 includes a spiral portion 321, and the spiral portion 321 is threadedly connected to the threaded portion 410 of the charging positive electrode 400.

[0038] It is understandable that the housing 100 can be made of metal materials such as stainless steel or aluminum alloy, which is not specifically limited here. The cross-section of the housing 100 can be circular, square, or other shapes, which is not specifically limited here. In the present embodiment, the cross-section of the housing 100 is circular, and one end is open and the other end is closed. This arrangement allows the barbecue temperature probe 10 to be better inserted into the barbecue to measure the temperature when in use, and can also effectively prevent the housing 100 from rusting due to grease, moisture and other substances.

[0039] Furthermore, the temperature measuring component 300 includes a temperature measuring body 310 and a radio frequency antenna 320, wherein the temperature measuring body 310 is electrically connected to the shell 100, so that the shell 100 is the charging negative electrode when the barbecue temperature probe 10 is charged, thereby increasing the contact area between the barbecue temperature probe 10 and the external power supply when charging, and the charging positive electrode 400 and the radio frequency antenna 320 are directly assembled together through a threaded connection, so that when the barbecue temperature probe 10 is charged, the radio frequency antenna 320 thread can be used as a wire to stably transmit current to the temperature measuring body, and the current flows out from the shell 100 after passing through the temperature measuring body, thereby forming a charging circuit with the charging positive electrode 400, the radio frequency antenna 320, the temperature measuring body and the shell 100 for charging the barbecue temperature probe 10, thereby avoiding the need to additionally set a wire to connect the charging positive electrode 400 with the temperature measuring body, thereby reducing the manufacturing cost of the barbecue temperature probe 10. At the same time, the assembly method in which the charging positive electrode 400 and the RF antenna 320 are directly assembled together through a threaded connection makes the connection between the charging positive electrode 400 and the RF antenna 320 more stable, and at the same time simplifies the assembly process during manufacturing, making the assembly more convenient, which is beneficial to improving the manufacturing efficiency of the barbecue temperature probe 10.

[0040] In order to isolate the housing 100 from the charging positive electrode 400 and prevent the user's hand from being burned when using the barbecue temperature probe 10 for temperature measurement, preferably, the handle 200 is made of insulating and high-temperature resistant materials such as ceramic material, plastic material, or glass material, which is not limited here. Such a configuration can avoid direct contact between the housing 100 as the charging negative electrode and the charging positive electrode 400, thereby avoiding the barbecue temperature probe 10 from short-circuiting during charging. In this embodiment, the handle 200 is provided with a second accommodating cavity 210 with openings at both ends, and the housing 100 and the handle 200 can be inserted into the handle 200 by the housing 100, or the handle 200 is inserted into the housing 100, or the housing 100 and the handle 200 are integrally connected so that the first accommodating cavity 110 and the second accommodating cavity 210 are connected, thereby forming an installation cavity for the internal functional structure of the barbecue temperature probe 10 to be installed.

[0041] In order to ensure a more stable connection between the RF antenna 320 and the charging positive electrode 400, preferably, the shape of the RF antenna 320 can be spring-shaped, tubular, or rod-shaped, which is not specifically limited here. At the same time, the RF antenna 320 is made of conductive materials such as copper or stainless steel.

[0042] In order to form a good connection between the RF antenna 320 and the charging positive electrode 400, preferably, the number of turns of the spiral portion 321 of the RF antenna 320 is not less than two turns. In this way, the RF antenna 320 can be stably connected to the charging positive electrode 400 to avoid oxidation and poor contact caused by high temperature.

[0043] The utility model provides a barbecue temperature probe 10, which includes a shell 100, a handle 200, a temperature measuring component 300 and a charging positive electrode 400. The shell 100 is made of metal material; the handle 200 has a second accommodating cavity with two ends opened, and the handle 200 is made of insulating material. The handle 200 is sleeved on the shell 100 and connected to the open end of the shell 100; the temperature measuring component 300 includes a temperature measuring body and a radio frequency antenna 320 electrically connected to the temperature measuring body, at least part of the radio frequency antenna 320 is arranged in the second accommodating cavity, and the temperature measuring body is electrically connected to the shell 100, so that the shell 100 is suitable for being used as a charging negative electrode; the charging positive electrode 400 is arranged in the second accommodating cavity and is located at one end of the handle 200 away from the shell 100, and a threaded portion is provided on the charging positive electrode 400, and the radio frequency antenna 320 includes a spiral portion 321, and the spiral portion 321 is threadedly connected to the threaded portion of the charging positive electrode 400. Such arrangement makes the shell 100 the charging negative electrode, increases the contact area between the barbecue temperature probe 10 and the external power supply, and makes the charging of the barbecue temperature probe 10 more stable. The charging positive electrode 400 and the radio frequency antenna 320 are directly assembled together through a threaded connection, so that when the barbecue temperature probe 10 is charged, the radio frequency antenna 320 thread can be used as a wire to stably transmit the current to the temperature measuring body. After passing through the temperature measuring body, the current flows out from the shell 100, thereby making the charging positive electrode 400, the radio frequency antenna 320, the temperature measuring body and the shell 100 form a charging circuit for charging the barbecue temperature probe 10, avoiding the need to additionally set a wire to connect the charging positive electrode 400 with the temperature measuring body, thereby reducing the manufacturing cost of the barbecue temperature probe 10. At the same time, the assembly method in which the charging positive electrode 400 and the RF antenna 320 are directly assembled together through a threaded connection makes it easy to adjust the length of the RF antenna 320 with the spiral portion 321 before mass production, making the connection between the charging positive electrode 400 and the RF antenna 320 more stable. At the same time, it simplifies the assembly process during manufacturing, making assembly more convenient, which is beneficial to improving the assembly and maintenance efficiency of the barbecue temperature probe 10.

[0044] See also Figure 4 or Fig. 9 In one embodiment, a groove 420 is provided at one end of the positive charging electrode 400 close to the outer shell 100, and the notch of the groove 420 is opened toward the temperature measuring body 310. The threaded portion 410 includes an internal thread provided on the inner side wall of the groove 420, and the spiral portion 321 is threadedly connected to the internal thread.

[0045] It is understandable that by setting the groove 420 with the notch facing the temperature measuring body 310, the RF antenna 320 or other structures inside the barbecue temperature probe 10 can be extended and arranged in the groove 420, so that the space utilization inside the barbecue temperature probe 10 is increased. At the same time, by threading the spiral portion 321 with the threaded portion 410 on the inner wall of the groove 420, the RF antenna 320 and the charging positive electrode 400 can be assembled together very easily and can be connected together very firmly. Such a setting effectively improves the assembly efficiency of the barbecue temperature probe 10, and at the same time avoids the separation between the RF antenna 320 and the charging positive electrode 400 when the barbecue temperature probe 10 is in use, thereby affecting the use of the barbecue temperature probe 10.

[0046] See also Figure 2 In one embodiment, the temperature measuring body 310 includes a circuit board 311 and a first temperature sensor 312 and a second temperature sensor 313 electrically connected to the circuit board 311 respectively, the first temperature sensor 312 is arranged in the first accommodating cavity 110, at least part of the second temperature sensor 313 is arranged in the second accommodating cavity 210, and the second temperature sensor 313 passes through the spiral portion 321 and extends into the groove 420.

[0047] It can be understood that the first temperature sensor 312 and the second temperature sensor 313 are electrically connected to the circuit board 311, so that the first temperature sensor 312 can transmit the measured signal to the second temperature sensor 313. When the barbecue temperature probe 10 is measuring the barbecue temperature, the first temperature sensor 312 is inserted into the barbecue to be measured along with the barbecue temperature probe 10, so that the barbecue temperature can be measured more accurately. The second temperature sensor 313 is arranged on the circuit board 311 and electrically connected to the first temperature sensor 312, so that the temperature signal measured by the first temperature sensor 312 can be transmitted to the second temperature sensor 313, and the temperature sending unit 314 of the second temperature sensor 313 then transmits the temperature signal to the radio frequency antenna 320.

[0048] Furthermore, the temperature measurement body 310 also includes a Bluetooth chip 361, which can provide Bluetooth transmission function for the radio frequency antenna 320, so that the radio frequency antenna 320 has a wireless Bluetooth transmission function and can send temperature signals to the outside world. At this time, the user can receive the temperature signal through a signal receiving device to obtain temperature information.

[0049] In addition, the temperature transmitting portion 314 passes through the spiral portion 321 of the RF antenna 320 and then extends into the groove 420. In this configuration, the temperature transmitting portion 314 is located in the spiral portion 321, so that the signal can be transmitted to the RF antenna 320 more stably. At the same time, the temperature transmitting portion 314 extends into the groove 420, saving the internal space of the barbecue temperature probe 10, thereby reducing the raw materials required for manufacturing the barbecue temperature probe 10, thereby reducing the manufacturing cost.

[0050] In order to realize the electrical connection between the housing 100 and the temperature measuring body 310, in the present embodiment, the temperature measuring body 310 further includes a charging negative electrode spring 316 and a capacitor 315. The charging negative electrode spring 316 connects the housing 100 and the temperature measuring body 310, so that the housing 100 becomes the charging negative electrode. Such a configuration increases the contact surface between the charging negative electrode and the external power supply, making the barbecue temperature probe 10 more stable during charging, and avoiding the phenomenon that the barbecue temperature probe 10 cannot be used due to unstable charging. The capacitor 315 can supply power to the barbecue temperature probe 10, so that the barbecue temperature probe 10 can work stably. When the capacitor 315 is insufficient in power, the capacitor 315 is charged by a charging circuit connected in sequence by the charging positive electrode 400, the radio frequency antenna 320, the charging negative electrode spring 316, the temperature measuring body 310 and the capacitor 315.

[0051] See also Fig.10 In one embodiment, the threaded portion 410 includes an external thread provided on the outer peripheral wall of the positive charging electrode 400, and the spiral portion 321 is threadedly connected to the external thread.

[0052] It is understandable that by spirally connecting the spiral portion 321 with the external thread on the outer peripheral wall of the positive electrode, the RF antenna 320 and the charging positive electrode 400 can be easily assembled together and can be firmly connected together. Such a configuration effectively improves the assembly efficiency of the barbecue temperature probe 10, and at the same time avoids the separation between the RF antenna 320 and the charging positive electrode 400 when the barbecue temperature probe 10 is in use, thereby affecting the use of the barbecue temperature probe 10. In addition, by providing two connection methods, an internal thread connection method and an external thread connection method, the assembly of the barbecue temperature probe 10 is more diversified, thereby improving the manufacturing efficiency of the barbecue temperature probe 10.

[0053] See also Fig.11In one embodiment, the end of the charging positive electrode 400 close to the shell 100 is provided with a groove 420 opening toward the temperature measuring body 310, and the temperature measuring body 310 includes a circuit board 311 and a first temperature sensor 312 and a second temperature sensor 313 electrically connected to the circuit board 311 respectively, the first temperature sensor 312 is arranged in the first accommodating cavity 110, and the second temperature sensor 313 passes through the spiral portion 321 and extends into the groove 420.

[0054] It can be understood that when the barbecue temperature probe 10 measures the barbecue temperature, the first temperature sensor 312 is inserted into the barbecue to be measured along with the barbecue temperature probe 10, so that the barbecue temperature can be measured more accurately. The second temperature sensor 313 is arranged on the circuit board 311 and electrically connected to the first temperature sensor 312, so that the temperature signal measured by the first temperature sensor 312 can be transmitted to the second temperature sensor 313, and the temperature sending part 314 of the second temperature sensor 313 transmits the temperature signal to the radio frequency antenna 320 and then sends it to the outside. At this time, the user can receive the temperature signal through the signal receiving device to obtain temperature information. In addition, the temperature sending part 314 passes through the spiral part 321 of the radio frequency antenna 320 and then extends into the groove 420. In this way, the temperature sending part 314 is located in the spiral part 321, so that the signal can be transmitted to the radio frequency antenna 320 more stably. At the same time, the temperature sending part 314 extends into the groove 420, saving the internal space of the barbecue temperature probe 10, thereby reducing the raw materials required for manufacturing the barbecue temperature probe 10, thereby reducing the manufacturing cost.

[0055] See also Figure 1 In one embodiment, the positive charging electrode 400 is disposed in the handle 200 and is flush with the wall of the handle 200 at one end away from the housing 100 .

[0056] It is understandable that the positive charging electrode 400 is disposed at one end of the housing 100 to prevent grease or moisture in the external environment from invading the interior of the barbecue temperature probe 10, further improving the service life and safety of the barbecue temperature probe 10. In this embodiment, the positive charging electrode 400 is disposed at the end of the handle 200 away from the housing 100 in a variety of ways, as described below:

[0057] For example, the positive charging electrode 400 is completely inserted into the second accommodating cavity 210, and the surface of the positioning section 430 thereof is flush with the end of the handle 200 away from the housing 100. In this way, the positive charging electrode 400 is completely arranged in the handle 200, which is conducive to improving the integrity and sealing of the barbecue temperature probe 10, and the handle 200 can be well held when the barbecue temperature probe 10 is used, avoiding interference of the positive charging electrode 400 with the hand when holding, so that the use experience of the barbecue temperature probe 10 is improved.

[0058] For another example, the positive charging electrode 400 is partially inserted into the second accommodating cavity 210, and a portion of the positioning section 430 thereof protrudes from the end of the handle 200 away from the housing 100. This arrangement enables the positive charging electrode 400 to be better connected to an external power source, thereby ensuring the charging stability of the barbecue temperature probe 10.

[0059] For another example, the positive charging electrode 400 can be set in a sleeve manner at one end of the handle 200 away from the housing 100. In this way, the positive charging electrode 400 can better prevent external pollutants from entering the barbecue temperature probe 10, thereby improving the service life of the barbecue temperature probe 10.

[0060] See also Figure 1 In one embodiment, an annular groove 120 is provided on the outer peripheral wall of the housing 100 , and the distance between the annular groove 120 and the end of the housing 100 away from the handle 200 is not less than 60 mm.

[0061] It is understandable that the annular groove 120 can be formed by machining, and the annular groove 120 is used as a mark of the insertion depth. In addition, laser engraving or silk screen printing can be performed in the annular groove 120 to further improve the recognition of the mark, so that the annular groove 120 can play a clearer marking role and will not fade as the barbecue temperature probe 10 is used for a longer time.

[0062] Furthermore, the distance between the position of the annular groove 120 and the end of the housing 100 away from the handle 200 is the minimum insertion depth of the barbecue temperature probe 10, and the minimum insertion depth can be set to 60 mm, or 70 mm, or 80 mm, and the specific value is not limited here. When the barbecue temperature probe 10 is inserted into the barbecue to measure the temperature, at least the distance between the position of the annular groove 120 and the end of the housing 100 away from the handle 200 is inserted into the barbecue. The temperature environment inside the barbecue is 70 to 80 degrees Celsius, so that the ambient temperature between the annular groove 120 and the end of the housing 100 away from the handle 200 is also between 70 and 80 degrees Celsius, and the temperature of other positions of the housing 100 will reach 200 degrees Celsius, and the capacitor 315, the negative charging spring 316 and other structures will fail at 100 degrees Celsius, or even be damaged. Therefore, the capacitor 315, the negative charging spring 316 and other structures inside the barbecue temperature probe 10 are arranged between the annular groove 120 and the end of the housing 100 away from the handle 200. In this way, the capacitor 315, the negative charging spring 316 and other structures will not be damaged due to excessive temperature.

[0063] See also Figure 5 , Fig.10 or Fig.13In one embodiment, the charging positive electrode 400 includes a positioning section 430 and a connecting section 440 that are connected to each other, and the second accommodating cavity 210 includes a first limiting hole 220 and an accommodating cavity 230 that are connected to each other, the aperture of the first limiting hole 220 is larger than the width of the accommodating cavity 230, the positioning section 430 is inserted into the first limiting hole 220 and abuts against the bottom wall of the first limiting hole 220, the threaded portion 410 is provided on the connecting section 440, and the connecting section 440 is inserted into the accommodating cavity 230 and is threadedly connected to the spiral portion 321 through the threaded portion 410.

[0064] It can be understood that a first abutting surface 250 is formed at the connection between the accommodating cavity 230 and the first limiting hole 220, and the first abutting surface 250 is arranged in a ring shape along the second accommodating cavity 210. The charging positive electrode 400 can abut against the first abutting surface 250 through the positioning section 430, so that the charging positive electrode 400 can be stably arranged in the first limiting hole 220, and the first abutting surface 250 is smoothly arranged, so that the gap width between the positioning section 430 and the first abutting surface 250 can be greatly reduced, thereby effectively preventing external pollutants from invading the interior of the barbecue temperature probe 10. The connecting section 440 is completely inserted into the accommodating cavity 230 for threaded connection with the radio frequency antenna 320. When the barbecue temperature probe 10 is in a charging state, the positioning section 430 of the charging positive electrode 400 is directly connected to the external power supply to input electricity. The charging positive electrode 400 is connected to the spiral portion 321 of the radio frequency antenna 320 through the groove 420 provided on the connecting section 440, thereby transmitting electricity to the temperature measuring body 310 for circulation. In this way, the charging positive electrode 400 is better connected to the radio frequency antenna 320 through the connecting section 440, thereby simplifying the manufacturing process of the barbecue temperature probe 10, reducing the materials required for manufacturing, and further reducing the manufacturing cost. At the same time, the radio frequency antenna 320 and the charging positive electrode 400 form good contact, avoiding oxidation and poor contact caused by high temperature.

[0065] See also Figure 5 or Fig.10 In one embodiment, a glue overflow groove 450 is provided on the outer peripheral wall of the positioning section 430 and / or the connecting section 440, and the charging positive electrode 400 is sealed and connected to the inner wall of the second accommodating cavity 210 of the handle 200 through sealant, and part of the sealant is arranged in the glue overflow groove 450.

[0066] It is understandable that a plurality of overflow glue grooves 450 are provided on the outer wall of the charging positive electrode 400. With such a configuration, after the gap between the charging positive electrode 400 and the second accommodating chamber 210 is injected with glue, it is possible to effectively prevent the glue from overflowing from the gap, which would cause inconvenience to the manufacture of the barbecue temperature probe 10, thereby improving the manufacturing efficiency of the barbecue temperature probe 10. In addition, when the barbecue temperature probe 10 is assembled by internal thread connection, the positioning section 430 and the connecting section 440 of the charging positive electrode 400 are both provided with overflow glue grooves 450, thereby preventing the overflow of glue to the greatest extent. When the barbecue temperature probe 10 is assembled by external thread connection, the groove 420 provided on the outer peripheral wall of the charging positive electrode 400 can serve as the overflow glue groove 450, and the overflow glue groove 450 only needs to be provided in the positioning section 430.

[0067] In addition, the positioning section 430 and the inner wall of the first limiting hole 220 form a first glue injection gap, and the first glue filling gap is used to inject glue to form a first sealing colloid. It can be understood that by injecting glue in the first glue injection gap to form the first sealing colloid, the gap between the charging positive electrode 400 and the first limiting hole 220 is perfectly filled, so that grease or moisture in the external environment can be better prevented from invading the interior of the barbecue temperature probe 10, further improving the service life and use safety of the barbecue temperature probe 10.

[0068] At the same time, in order to increase the service life of the first sealing colloid, the selected colloid should be able to achieve tight and seamless adhesion on various materials, maintain good adhesion in various environments, adapt to the slight deformation of different objects during use, and have good high temperature resistance. In this way, the barbecue temperature probe 10 still has a good sealing effect in a high temperature working environment.

[0069] See also Figure 6 or Fig.11 In one embodiment, the groove width of the groove 420 is not less than 3.0 mm. It is understandable that the outer diameter length of the groove 420 of the charging positive electrode 400 can be set to 3.0 mm, or 3.5 mm, or 4.0 mm, and the specific value is not limited here. In this way, the notch of the groove 420 can allow the spiral portion 321 of the radio frequency antenna 320 to extend into it and be spirally connected to the groove 420, and at the same time, the temperature sending portion 314 of the second temperature sensor 313 can also extend into it, and the second temperature sensor 313 is kept at a certain distance from the radio frequency antenna 320. When the barbecue temperature probe 10 is working, the second temperature sensor 313 will not affect the working performance of the radio frequency antenna 320.

[0070] See also Fig.14In this embodiment, the second accommodating cavity 210 also includes a second limiting hole 240, which is disposed at one end of the second accommodating cavity 210 close to the shell 100, the accommodating cavity 230 is communicated with the second limiting hole 240, and a second abutting surface 260 is formed at the connection between the accommodating cavity 230 and the second limiting hole 240, and the second abutting surface 260 is arranged in a ring shape along the second accommodating cavity 210, and the shell 100 has an open end which is inserted into the second limiting hole 240 and abuts against the second abutting surface 260.

[0071] It is understandable that inserting the open end of the housing 100 into the second limiting hole 240 makes the first accommodating cavity 110 and the second accommodating cavity 210 of the housing 100 communicate with each other, thereby facilitating the installation of various functional structures. At the same time, the maximum insertion length of the housing 100 can be limited by setting the second abutting surface 260. Such a setting can effectively prevent the housing 100 from being inserted into the accommodating cavity 230, thereby preventing the housing 100 from affecting the structures such as the RF antenna 320 in the accommodating cavity 230. At the same time, the second abutting surface 260 is arranged in an annular shape, which can make the housing 100 abutting on the second abutting surface 260 more stable.

[0072] In this embodiment, the housing 100 and the inner wall surface of the second limiting hole 240 form a second glue injection gap, and the second glue filling gap is used to inject glue to form a second sealing colloid. It can be understood that by injecting glue into the second glue injection gap to form the second sealing colloid, the gap between the negative charging electrode spring 316 and the second limiting hole 240 is completely filled, so that grease or moisture in the external environment can be better prevented from invading the interior of the barbecue temperature probe 10, and the service life and use safety of the barbecue temperature probe 10 are further improved.

[0073] At the same time, in order to increase the service life of the second sealing colloid, the selected colloid should be able to achieve tight and seamless adhesion on various materials, maintain good adhesion in various environments, adapt to the slight deformation of different objects during use, and have good high temperature resistance. In this way, the barbecue temperature probe 10 still has a good sealing effect in a high temperature working environment.

Since the wireless Bluetooth barbecue thermometer adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0075] It can be understood that the storage box includes a battery assembly and a first signal module and a second signal module electrically connected to the battery assembly. The battery assembly is arranged in the storage box for powering the barbecue temperature probe 10. The storage groove is arranged on the outer surface of the storage box for storing and charging the barbecue temperature probe 10. The first signal module and the second signal module are arranged inside the storage box. The first signal module is used to receive the wireless Bluetooth temperature signal sent by the barbecue temperature probe 10. The first signal module is electrically connected to the second signal module, so that the first signal module transmits the received wireless Bluetooth temperature signal to the mobile phone APP or other signal receiving device through the second signal module.
