Description

Technical Field

[0001] This utility model belongs to the technical field of thermometers, specifically relating to a kitchen thermometer, and particularly to a food temperature measuring device for measuring the temperature change of meat products during the roasting process. Background Technology

[0002] A food thermometer is a type of kitchen thermometer. When using a food thermometer, it is typically inserted into the food to be cooked, allowing for real-time temperature monitoring during the cooking process. Currently, meat thermometers on the market use supercapacitors (also known as farad capacitors) as their power source. A drawback of supercapacitors is their self-discharge effect, which rapidly depletes their charge, potentially causing the thermometer to malfunction. Furthermore, existing meat thermometers have a complex design, making assembly and use inconvenient; their structure needs further optimization. Utility Model Content

[0003] Therefore, it is necessary to provide a food temperature measuring device that can charge the thermometer at any time using a charging box, and whose thermometer body is easy to remove and put into the storage box.

[0004] One embodiment of the present invention relates to a food temperature measuring device, which includes a charging box and a food thermometer that is detachably housed within the charging box.

[0005] The charging box is used to charge the food thermometer and includes a body and an end cap.

[0006] One end of the end cap is rotatably pivotally connected to the upper end of the body, and the other end of the end cap can rotate back and forth relative to the body.

[0007] After the other end of the end cap is screwed away from the body, the opening at the upper end of the body is exposed, so that the food thermometer can be inserted into and housed in the charging case for charging.

[0008] Furthermore, a receiving sleeve is provided on one side of the main body along its length, and the food thermometer is housed within the receiving sleeve.

[0009] The interior of the receiving sleeve has a retaining ring and a first elastic element installed at the end away from the end cap.

[0010] One end of the first elastic element is fixed with a retaining ring, and the other end abuts against the bottom wall of the main body away from the end cap.

[0011] During the process of inserting the food thermometer into the receiving sleeve, the front end of the food thermometer passes through the fixing ring and the first elastic member, and drives the fixing ring to move downward, thereby compressing the first elastic member through the fixing ring;

[0012] When the food thermometer is fully housed within the receiving sleeve, the first elastic element is compressed and accumulates elastic potential energy, thereby imparting elastic force to the food thermometer.

[0013] Furthermore, after the other end of the end cap is rotated away from the upper surface of the main body, the lower end of the end cap releases the pressure on the food thermometer, and the food thermometer automatically pops out from the charging case under the action of the elastic restoring force released by the first elastic member.

[0014] Furthermore, the inner wall of the receiving sleeve is formed with a stepped structure. During the process of the food thermometer popping out, the stepped structure will stop the fixing ring and prevent the fixing ring from detaching from the receiving sleeve along with the food thermometer.

[0015] Furthermore, the upper end of the main body is provided with a pivot portion that is connected to the end cap. One end of the end cap rotates forward or backward relative to the main body about the pivot portion as a rotation axis, and can be positioned in the rotated position.

[0016] Furthermore, the pivot portion allows a wire connected to the control circuit board inside the main body to pass through, and the wire is electrically connected to the food thermometer to charge the food thermometer.

[0017] Furthermore, the end cap further houses a printed circuit board, a connector, and a second elastic element.

[0018] One end of the second elastic member abuts against the lower surface of the printed circuit board and is electrically connected to it, while the other end of the second elastic member passes through the connector and is electrically connected to a conductive portion disposed at the lower end of the connector.

[0019] The wire passes through the pivot and is electrically connected to the printed circuit board, and is electrically connected to the food thermometer through the conductive part.

[0020] Furthermore, the food thermometer also includes a charging positive electrode pin located at its upper end, the charging positive electrode pin being in detachable contact with the conductive part;

[0021] When one end of the end cap is returned from the rotated position to directly above the body, the conductive part is electrically connected to the charging positive electrode pin, thereby charging the food thermometer through the battery of the body.

[0022] Furthermore, the food thermometer internally includes a main PCB board, a temperature sensor, a communication unit, and an antenna unit.

[0023] The temperature sensor and the communication unit are both integrated on the main PCB board, and the charging positive electrode pin is located at the upper end of the main PCB board;

[0024] The temperature sensor is used to sense the obtained temperature information;

[0025] The communication unit is a Bluetooth chip, which is electrically connected to the temperature sensor and is used to transmit the temperature information to an external terminal device or display device through the antenna unit.

[0026] Furthermore, a display screen is provided on the back of the main body of the charging case. The display screen is electrically connected to the control circuit board and battery disposed inside the charging case via leads.

[0027] A data transmission line is fixed on the main PCB board, and the temperature sensor is electrically connected to the control circuit board through the data transmission line.

[0028] A microprocessor is also fixed on the control circuit board. The microprocessor can receive digital signals transmitted from the temperature sensor and display the digital signals through the display screen.

[0029] The display screen is also used to display the remaining battery power of the food thermometer and the charging status of the charging case for the food thermometer.

[0030] According to the food temperature measuring device of this utility model, one end of the end cap of the charging box can rotate at a certain angle relative to the main body of the charging box. When the end cap is rotated away from the main body, the food thermometer stored in the charging box can automatically pop upwards, greatly simplifying the user's loading and unloading operations. Furthermore, when it is necessary to store the food thermometer in the charging box, simply press the food thermometer gently down until its upper end is flush with the upper surface of the box, then rotate the end cap back to its original position to securely store the thermometer and automatically start the charging process. This innovative storage and charging mechanism not only optimizes the operation process but also ensures that the food thermometer can be cyclically charged through the charging box. In particular, the charging box can adopt a TEP-C interface, supporting cyclic charging for extended battery life, significantly improving the product's convenience and environmental friendliness, while also enhancing the user experience.

Detailed Implementation

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0045] Please also refer to Figures 1 to 3 The food temperature measuring device 100 of this utility model includes a charging case 10 and a food thermometer 20. The overall appearance of the food temperature measuring device 100 resembles a lighter or a long, narrow power bank, making it lightweight and portable. The food thermometer 20 is housed within the charging case 10 along its long axis on one side. Specifically, the charging case 10 is used to charge the food thermometer 20 in real time. The food thermometer 20 is housed within the charging case 10 and can automatically pop out from it.

[0046] The charging case 10 includes a body portion 11 and an end cap 13 rotatably mounted on one end of the body portion 11. The body portion 11 includes an inner frame 111 and an outer shell 110 covering the outer periphery of the inner frame 111.

[0047] The inner frame 111 is a front-open receiving groove structure formed by a top wall 111a, a bottom wall 111b, two opposing side walls 111c, and a rear wall 111d. It houses the receiving sleeve 12 (described later), a control circuit board 30, a battery 40, and other components. One end of the end cap 13 is pivotally connected to one side of the top wall 111a of the inner frame 111, allowing the end cap 13 to rotate relative to the main body 11. At the junction of the side wall 111c and the top wall 111a of the inner frame 111, away from the pivot point of the end cap 13, a narrow opening 1111 is formed, penetrating both the side wall 111c and the top wall 111a. The opening 1111 guides the ejection direction of the food thermometer 20, ensuring that the food thermometer 20 ejects vertically upwards along the direction of the opening 1111 during ejection. Furthermore, the opening 1111 facilitates the removal and insertion of the food thermometer 20 from the charging case 10.

[0048] The outer shell 110 is made of metal and is a hollow, open-end flat strip-shaped shell structure used to fit and cover the outer periphery of the inner frame 111. A narrow opening 1101 is also formed in the side wall of the outer shell 110. When the outer shell 110 is fitted onto the inner frame 111, the opening 1101 of the outer shell 110 corresponds to the opening 1111 of the inner frame 111. Two recesses (reference numerals) are spaced apart on the rear wall 111d of the inner frame 111, and magnets 105 are embedded within these recesses. The magnets 105 can exert a certain attractive force on the outer shell 110 to securely fix it in place.

[0049] A receiving sleeve 12 is further installed inside the inner frame 111 of the main body 11. The receiving sleeve 12 is installed on one side of the inner frame 111 along the length of the main body 11. It is a hollow cylindrical body used to house the food thermometer 20. The top end of the receiving sleeve 12 has an opening 12a. The opening 12a penetrates the top wall 111a of the inner frame 111 and connects the opening 1111 and the opening 1101. Thus, the food thermometer 20 can be inserted into the receiving sleeve 12 from the top wall 111a of the main body 11 through the opening 12a. Please refer to... Figure 4 and Figure 5 One end of the receiving sleeve 12 abuts against the inner surface of the top wall 111a of the main body 11, which contacts the end cap 13, and the other end abuts against a baffle 107 installed near the bottom wall 111b. The top wall of the inner frame 111 of the main body 11 is also provided with a pivot portion 16 that is rotatably connected to the end cap 13. The pivot portion 16 is a hollow cylinder that allows wires inside the main body 11 to pass through. One end of the end cap 13 rotates relative to the main body 11 about the pivot portion 16 as its axis of rotation. Figure 2 The arrow A indicates that the direction of the rotation is backward or along the direction of the arrow. Figure 3The arrow B shown rotates forward and can be positioned in the rotated position. Preferably, the rotation angle of one end of the end cap 13 relative to the body portion 11 is 0~45°.

[0050] like Figure 2 and Figure 3 As shown, the end cap 13 includes a cover body 131 with a cavity and a base portion 132, the cover body 131 and the base portion 132 being sleeved and engaged together. In one embodiment, the cover body 131 and the base portion 132 are integrally formed, and the lower end surface of the base portion 132 is a smooth surface. Correspondingly, the surface of the top wall 111a of the inner frame 111 is also a smooth plastic plate, facilitating seamless connection with the lower end surface of the base portion 132.

[0051] like Figure 4 , Figure 5 as well as Figure 6 As shown, the end cap 13 further houses a button 133, a printed circuit board 134, a connector 135, and a second elastic member 136. A through hole is provided on the end face of the cover 131, through which the upper surface of the button 133 protrudes. By pressing the button 133, the user can trigger the contacts on the printed circuit board 134, thereby confirming the power level of the food temperature measuring device 100. The printed circuit board 134 is located below the button 133, and the button 133 contacts the contacts 1341 on the upper surface of the printed circuit board 134. The second elastic member 136 is disposed within the connector 135, with one end abutting against the lower surface of the printed circuit board 134 and electrically connected to it, and the other end passing through the connector 135 and abutting against and electrically connected to the conductive portion 138 disposed at the lower end of the connector 135.

[0052] Furthermore, since one end of the end cap 13 can rotate relative to the body portion 11, in order to improve the stability of the end cap 13 relative to the body portion 11 when it is reset, and to prevent the end of the end cap 13 away from the pivot portion 16 from rotating freely relative to the body portion 11 when the food temperature measuring device 100 is detached from the upper end of the body portion 11 due to external force, a magnetic attraction device can be provided between the end cap 13 and the body portion 11. In this embodiment, as shown... Figure 5 As shown, a magnet 14 is fixed to the upper surface of the base portion 132 of the end cap 13, and another magnet 14 with opposite magnetic poles is fixed to the inner surface of the top wall 111a of the body portion 11 adjacent to the base portion 132. Thus, the end cap 13 can be positioned at the upper end of the body portion 11 by the mutual magnetic attraction of the two magnets 14 with opposite magnetic poles, and its end away from the pivot portion 16 will not easily detach from the body portion 11.

[0053] Please review Figure 1The food temperature measuring device 100 further includes a control circuit board 30 installed within the main body 11, a battery 40, a lamp holder 50 fixed to one long side of the control circuit board 30, an alarm 60 fixed at intervals to one short side of the control circuit board 30, a USB charging interface 70, and multiple wires 80. The battery 40, the lamp holder 50, the alarm 60, the USB charging interface 70, and the multiple wires 80 are all electrically connected to and controlled by the control circuit board 30. For example, the control circuit board 30 can control the charging action of the battery 40, the flashing of the indicator light on the lamp holder 50, and the flashing or beeping of the alarm 60. A detection switch 31 is also fixed to one end of the control circuit board 30 opposite to the lamp holder 50. One end of the detection switch 31 passes through the outer shell of the receiving sleeve 12 and is electrically connected to the food thermometer 20 housed therein. The detection switch 31 is used to detect the charge level of the food thermometer 20. For example, when the charging box 10 fully charges the food thermometer 20, the control circuit board 30 will control the alarm 60 to flash red light to alert the user.

[0054] In this embodiment, the lamp holder 50 is provided with an indicator light 51 for displaying the battery power of the 40, an indicator light 52 for displaying the power of the food thermometer 20, and a wireless signal indicator light 53; the alarm 60 includes a set of luminous alarm lights 61. The indicator lights 51, 52, 53, the alarm lights 61, and the USB charging interface 70 are exposed from the through hole in the housing 110 and the opening in the bottom wall 111b of the main body 11, respectively. One end of a set of wires 80 is electrically connected to the battery 40, and the other end is electrically connected to the control circuit board 30; one end of another set of wires 80 is connected to the control circuit board 30, and the other end passes through the pivot part 16 and is electrically connected to the printed circuit board 134.

[0055] Understandably, in a modified version, the charging case 10 can also use a Tepc-C interface to replace the USB charging interface 70. The Tepc-C interface can achieve fast charging, greatly improving the charging efficiency of the charging case 10, thereby enabling cyclic charging of the food thermometer 20, improving the battery life of the food thermometer 20, and significantly enhancing the convenience and environmental friendliness of the food thermometer 20 when used.

[0056] Furthermore, such as Figure 1 As shown, a drain hole 90 is also provided on the bottom wall 111b of the main body 11 away from the end cover 13. The drain hole 90 is used to discharge the water vapor inside the charging case 10 to the outside and helps the charging case 10 dissipate heat.

[0057] like Figure 2 , Figure 4 , Figure 5 as well as Figure 6 As shown, the thermometer housing 22, in terms of its external appearance, includes a probe portion 221 for at least partially inserting into food and a handle portion 223 connected to one end of the probe portion 221. The probe portion 221 is a metal rod made of stainless steel or the like, and the handle portion 223 is an insulator. A first elastic member 21 is provided at the bottom of the receiving sleeve 12. A retaining ring 222 is fixed to one end of the first elastic member 21, and the other end abuts against the bottom wall 111b of the body portion 11 away from the end cap 13. Most of the first elastic member 21 and the retaining ring 222 are housed within the receiving sleeve 12 at the end away from the end cap 13, and the retaining ring 222 can move up and down with the first elastic member 21. During the process of inserting the food thermometer 20 into the receiving sleeve 12, the front end of the probe portion 221 will penetrate into the retaining ring 222 and the first elastic member 21, engaging with the inner wall of the retaining ring 222, thereby causing the retaining ring 222 to move downward, and thus compressing the first elastic member 21 through the retaining ring 222. With the food thermometer 20 fully retracted into the receiving sleeve 12, the first elastic element 21 is in a compressed state and accumulates elastic potential energy, thereby giving the food thermometer 20 elastic force.

[0058] When the end cap 13 away from the pivot portion 16 (also referred to as the "rotating end") is rotated away from the upper end face of the body portion 11, the conductive portion 138 at the lower end of the end cap 13 releases the pressure on the food thermometer 20, and the food thermometer 20 pops out from the receiving sleeve 12 of the charging box 10. During the popping process, the step structure (step portion) 121 formed on the inner wall of the receiving sleeve 12 will stop the retaining ring 222, preventing it from detaching from the receiving sleeve 12 along with the food thermometer 20.

[0059] In this embodiment, the handle portion 223 is made of ceramic material, which serves as insulation and heat insulation. The handle portion 223 encloses the first part 231 of the main PCB board 23, and the first part 231 is fixedly connected to the inner wall of the handle portion 223. More specifically, the handle portion 223 encloses the antenna unit 26 and the charging positive electrode pin 27. In this embodiment, the handle portion 223 can be made of an insulating material that can withstand high temperatures and has low thermal conductivity, such as ceramic material. In addition, a mounting plate 224 is integrally formed on the upper end of the handle portion 223. The mounting plate 224 protrudes vertically from the side wall of the handle portion 223 and is used to be received in the opening 1111 of the side wall of the outer casing 110, and facilitates the user's grip on the food thermometer 20. By providing the handle portion 223, on the one hand, the antenna unit 26 and the first part 231 can be securely fixed inside the handle portion 223, ensuring the stability of the electrical connection between these components and other components; on the other hand, the handle portion 223 has a heat insulation function, which can reduce the adverse effects of the high temperature environment outside the handle portion 223 on the antenna unit 26 and the first part 231 when the food thermometer 20 is used during the cooking process. In some embodiments, the temperature sensor 24 includes a first temperature sensor and a second temperature sensor. The first temperature sensor is disposed in the tip portion 2210 of the probe portion 221 for sensing the internal temperature of the food. The second temperature sensor is disposed in the handle portion 223 for sensing the ambient temperature. The first temperature sensor is in contact with the tip portion 2210 to sense the internal temperature of the food via the tip portion 2210; the second temperature sensor is in contact with the charging positive electrode pin 27 to sense the ambient temperature (e.g., the temperature inside an oven) via the charging positive electrode pin 27. In the above embodiment, the charging positive electrode pin 27 also serves as a heat conduction element when the second temperature sensor senses the ambient temperature, which improves the accuracy of the second temperature sensor in sensing the ambient temperature, while avoiding exposing the second temperature sensor to the thermometer housing 22 and ensuring the sealing performance of the thermometer housing 22.

[0060] Please refer to the following: Figure 2 and Figure 7 The food thermometer 20 includes a thermometer housing 22, a main PCB board 23 disposed within the thermometer housing 22, a temperature sensor 24, a communication unit 25, and an antenna unit 26. Both the temperature sensor 24 and the communication unit 25 are electrically connected to the main PCB board 23. The temperature sensor 24 is used to sense the acquired temperature information. The communication unit 25 is a Bluetooth chip, electrically connected to the temperature sensor 24, and is used to transmit the temperature information outward through the antenna unit 26.

[0061] In this embodiment, both the communication unit 25 and the antenna unit 26 are integrated on the main PCB board 23. The main PCB board 23 includes a first portion 231 extending into the handle portion 223 and a second portion 232 located within the probe portion 221. The antenna unit 26 is located on the first portion 231, and the communication unit 25 is located on the second portion 232.

[0062] In this embodiment, the food thermometer 20 also includes a positive charging pin 27 disposed on the main PCB board 23, away from the tip 2210. The positive charging pin 27 is in detachable contact with the conductive part 138. When one end of the end cap 13 is returned from the rotated position to directly above the body 11, the conductive part 138 and the positive charging pin 27 are electrically connected, thereby starting to charge the food thermometer 20 through the battery 40 inside the body 11.

[0063] Please refer to the following: Figure 6 and Figure 7 In this embodiment, the food thermometer 20 further includes a power storage unit 28 disposed on the end of the main PCB board 23 opposite to the charging positive electrode pin 27. The power storage unit 28 is disposed within the probe portion 221, adjacent to the tip 2210 of the probe portion 221. The power storage unit 28 is electrically connected to the main PCB board 23 to supply power to the main PCB board 23. In some embodiments, the power storage unit 28 is a supercapacitor. The detection switch 31 is used to detect the charge level of the power storage unit 28.

[0064] In the above embodiment, the food thermometer 20 is used in conjunction with the charging case 10. When the food thermometer 20 is stored in the charging case 10, the probe part 221 of the food thermometer 20 is usually confined within the receiving sleeve 12 of the charging case 10, so that the relative position of the probe part 221 within the charging case 10 is relatively stable.

[0065] The following describes the relationship between the charging box 10 of the food temperature measuring device 100 and the food thermometer 20.

[0066] Please refer to the following: Figure 2 , Figure 3 , Figure 5 as well as Figure 6When a user wants to store the food thermometer 20 in the charging case 10, they press down on the top of the handle 223 of the food thermometer 20 until it is roughly flush with the upper surface of the main body 11. Then, they turn the end cap 13 away from the pivot 16 back and position it to mate with the main body 11. This reliably stores the food thermometer 20 and begins the charging process. More specifically, after the food thermometer 20 is fully inserted into the charging case 10, the hanging piece 224 on the side of the handle 223 is received in the opening 1111 on the upper side wall of the charging case 10. The conductive part 138 at the lower end of the end cap 13 abuts against the positive charging pin 27 at the upper end of the food thermometer 20 and is electrically connected, thereby enabling the charging case 10 to charge the food thermometer 20 in real time. At this time, the front end of the food thermometer 20 is engaged in the fixing ring 222 inside the receiving sleeve 12, and the fixing ring 22 presses down on the first elastic member 21, thereby causing the first elastic member 21 to contract and accumulate elastic potential energy.

[0067] When the food thermometer 20 needs to be removed, the user can pry the end of the end cap 13 away from the pivot 16 from both sides. At this time, the other end of the end cap 13 will rotate around the pivot 16. When the end of the end cap 13 away from the pivot 16 is rotated away from the upper end surface of the body 11, the conductive part 138 on the lower end surface of the end cap 13 will release the pressure on the charging positive electrode pin 27 of the food thermometer 20. At this time, the first elastic member 21 surrounding the tip 2210 of the food thermometer 20 will elastically reset, so that the food thermometer 20 will automatically pop out of the charging case 10 under the action of the elastic restoring force released by the first elastic member 21. Afterwards, the user can easily take the food thermometer 20 out of the charging case 10 by holding the hanging piece 224.

[0068] like Figure 8 As shown, the food thermometer 20 can wirelessly communicate with a terminal device such as a mobile phone 200 or other display devices through its communication unit 25 and antenna unit 26, transmitting its own battery information or the measured food temperature and ambient temperature data signals to the terminal device or display device. For example, if the mobile phone 200 has an APP installed to work with the food temperature measuring device 100, when the probe part 221 of the food thermometer 20 is inserted into meat such as steak or pork chop 300, the user can open the APP to view the battery information of the food thermometer 20 and the measured food temperature and ambient temperature data in real time.

[0069] like Figure 9As shown, the food temperature measuring device 100 of this utility model also has another function. Specifically, since the end of the end cap 13 away from the pivot 16 can rotate relative to the main body 11 by a maximum angle of 45 degrees, after the end of the end cap 13 away from the pivot 16 is rotated away from the main body 11, a certain angle is formed between the end cap 13 and the upper surface of the main body 11; at the same time, the food thermometer 20 automatically pops out from the charging box 10, with a portion protruding from the upper surface of the main body 11. Thus, the handle portion 223 of the food thermometer 20 protruding from the main body 11 cooperates with the rotating end 17 of the end cap 13 to form a support structure, tilting and supporting the main body 11. In this way, the user can place the entire charging box 10 tilted on the table for easy access and to save space.

[0070] like Figure 10 As shown, as a variation of this utility model, a display screen 112 can also be provided on the back of the main body 11 of the food temperature measuring device 100. The display screen 112 is exposed through an opening in the outer casing 110. The display screen 112 is electrically connected to the control circuit board 30 and the battery 40 of the charging box 10 via leads, so that the control circuit board 30 can control the opening and closing of the display screen 112 and the content displayed. A data transmission line is fixed on the main PCB board 23 inside the food thermometer 20, and the temperature sensor 24 is electrically connected to the control circuit board 30 via the data transmission line. A microprocessor is also fixed on the control circuit board 30. The microprocessor can receive the digital signal transmitted from the temperature sensor 24 of the food thermometer 20 and display the digital temperature signal on the display screen 112. After the temperature sensor 24 inside the probe part 221 measures the internal temperature of the food, it converts the real-time temperature into a digital signal and transmits the digital signal to the microprocessor on the control circuit board 30 for data processing and conversion via the data transmission line, and then displays it on the display screen 112. In addition, the display screen 112 can also display information such as the power level of the energy storage unit 28 of the food thermometer 20 and the charging status of the charging box 10 for the food thermometer 20. In this way, users can obtain the information they need in real time through the display screen 112, resulting in a better user experience.
