[0036] The utility model will be made further detailed description through specific implementation mode combining with the drawings. In which the similar element in different implementation modes adopts the relevant similar element mark. In the following implementation mode, many details are described in order to make the application can be better understood. However, the person skilled in the art can easily realize that part of the features can be omitted in different cases, or can be replaced by other elements, materials, methods. In some cases, some operations related to the application are not shown or described in the specification in order to avoid the core part of the application from being overwhelmed by too much description, and for the person skilled in the art, detailed description of the related operation is not necessary, they can complete the understanding of the related operation according to the description in the specification and the general technical knowledge in the art.

[0037] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. At the same time, the steps or actions in the method description can also be sequentially changed or adjusted in a manner obvious to those skilled in the art. Therefore, the various sequences in the specification and drawings are only for clear description of a certain embodiment, and do not mean the necessary sequence, unless otherwise stated that a certain sequence must be followed.

[0038] The serial numbers of components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and have no any sequence or technical meaning. The "connection" and "coupling" in this application include direct and indirect connection (coupling) unless otherwise specified.

[0039] In one embodiment, a wireless probe base is provided, which forms a wireless probe device with a wireless probe. The wireless probe can be inserted into food, food materials and other materials to detect the temperature thereof. The wireless probe base is wirelessly connected with the wireless probe to receive the food temperature signal collected and transmitted by the wireless probe. The wireless probe base can also be wirelessly connected with a terminal such as a mobile phone, a tablet computer, a notebook computer, etc. to transmit the received food temperature signal to the terminal. The wireless probe base serves as a relay or transfer component to transfer the food temperature signal collected by the wireless probe to the terminal such as a mobile phone, a tablet computer, a notebook computer, etc. The wireless probe base can transmit the received food temperature signal directly to the terminal, or can transmit the received food temperature signal to the terminal after processing. The wireless probe does not need to communicate directly with the terminal, and miniaturization of the wireless probe can be achieved.

[0040] The wireless probe base can also be used to store and place the wireless probe, so as to avoid loss of the wireless probe and contamination of the wireless probe.

[0041] The wireless probe base of this embodiment is provided with a first antenna and a second antenna. The first antenna is used for wireless communication with the wireless probe, and the second antenna is used for communication with terminals such as mobile phones, tablets, and laptops. The first antenna and the second antenna are arranged far away from each other to reduce mutual interference between the first antenna and the second antenna, so that the first antenna and the second antenna can communicate stably and accurately respectively, thereby improving the user experience of the wireless probe device.

[0042] Please refer to Figures 1 to 5 The wireless probe base 100 of this embodiment mainly includes a housing 1 and a circuit board 2 , and the circuit board 2 is arranged in the housing 1 .

[0043] The shell 1 can be a long strip structure, and the shell 1 includes a top, a bottom and a side. The top and the bottom are located at the two ends of the length direction of the shell 1. The side encloses the area between the top and the bottom. The side is a ring body. The top, the bottom and the side enclose a shell 1 with a cavity. The length of the shell 1 is slightly larger than the length of the wireless probe 200. The shell 1 can be provided with a slot 11. The slot 11 is provided at the top of the shell 1. The opening of the slot 11 is located at the end of the shell 1. The slot 11 extends along the length direction of the shell 1. The slot 11 is used to plug in the wireless probe 200, so as to realize the hidden storage and fixation of the wireless probe 200 to avoid the loss of the wireless probe 200 when not in use, and can also protect the wireless probe 200. The slot 11 can also be provided at the bottom or side of the shell 1, and there is no limitation here.

[0044] In other embodiments, the shell 1 may also not be provided with the slot 11, and a first magnetic attraction portion is provided on the outer surface or interior of the shell 1, and the wireless probe 200 is provided with a corresponding second magnetic attraction portion. The first magnetic attraction portion and the second magnetic attraction portion can be a combination of magnetic blocks with different magnetic properties, or a combination of a magnetic block and a metal block that can be magnetically attracted. The magnetic attraction force formed between the first magnetic attraction portion and the second magnetic attraction portion can magnetically fix the wireless probe 200 to the surface of the shell 1, and can also realize the storage and fixation of the wireless probe 200.

[0045] In other embodiments, the housing 1 may also have other shapes. For example, the housing 1 may be a disc structure. The housing 1 with this structure may be provided with a slot for inserting and fixing the wireless probe 200. Most of the wireless probe 200 is exposed outside the housing 1. This housing 1 can realize the placement and fixation of the wireless probe 200.

[0046] In this embodiment, the housing 1 can be made of plastic, which will not interfere with wireless communication. The housing 1 has a receiving cavity, and the circuit board 2 is fixed in the receiving cavity of the housing 1 by screw connection, clamping, bonding, etc.

[0047] Several components are assembled on the circuit board 2, and the circuit board 2 is mainly provided with a first antenna 21, a second antenna 22 and a processor 23. The circuit board 2 can be a plate structure, and the circuit board 2 can be a polygonal structure. For example, the circuit board 2 is a long strip of board, and the circuit board 2 extends along the length direction of the shell 1 to make full use of the space inside the shell 1.

[0048] The first antenna 21 and the second antenna 22 are electrically connected to the processor 23 respectively. The processor 23 is used to control the first antenna 21 and the second antenna 22 to send and receive signals.

[0049] The first antenna 21 is used for wireless communication with the wireless probe 200 and is primarily used to receive food temperature signals collected and transmitted by the wireless probe 200. The second antenna 22 is used for wireless communication with a terminal 300, such as a mobile phone, tablet, or laptop computer, and is primarily used to transmit food temperature signals to the terminal 300, such as a mobile phone, tablet, or laptop computer, so that the terminal 300, such as a mobile phone, tablet, or laptop computer, can collect and view the food temperature signals collected by the wireless probe 200.

[0050] The processor 23 can control the second antenna 22 to directly transmit the food temperature signal received by the first antenna 21 to the terminal 300. The processor 23 can also first process the food temperature signal received by the first antenna 21, such as by filtering or performing analog-to-digital conversion, and then control the second antenna 22 to transmit the processed food temperature signal to the terminal 300. The processed food temperature signal can improve the stability of wireless transmission.

[0051] In this embodiment, the first antenna 21 is located away from the bottom of the housing 1, and the first antenna 21 and the second antenna 22 are located away from each other. For example, the first antenna 21 can be located near the top of the housing 1, and the second antenna 22 can be located in the middle or bottom of the housing 1; alternatively, the first antenna 21 can be located in the middle of the housing 1, and the second antenna 22 can be located near the bottom or top of the housing 1. In either case, the first antenna 21 and the second antenna 22 can be located away from each other to avoid mutual interference between the first antenna 21 and the second antenna 22.

[0052] In this embodiment, the bottom portion is located near the hand-held position, and holding the device with the hand can easily affect signal transmission. The first antenna 21 is located at a position away from the bottom of the housing 1, and the first antenna 21 and the second antenna 22 are positioned away from each other. For example, the first antenna 21 can be located near the top of the housing 1, and the second antenna 22 can be located in the middle or bottom of the housing 1; alternatively, the first antenna 21 can be located in the middle of the housing 1, and the second antenna 22 can be located near the top of the housing 1. In either case, the first antenna 21 and the second antenna 22 can be positioned away from each other to avoid mutual interference between the first antenna 21 and the second antenna 22, and further prevent interference with the signal from external factors.

[0053] In this embodiment, processor 23 is located in or near the center of circuit board 2, and first antenna 21 and second antenna 22 are spaced apart and located on different sides of circuit board 2. The placement of first antenna 21 and second antenna 22 at the edges of circuit board 2 prevents communication interference with first antenna 21 and second antenna 22 from other components within circuit board 2.

[0054] Circuit board 2 includes multiple sides. Circuit board 2 has a rectangular or approximately rectangular structure and includes a first side 2a and a second side 2b. First side 2a is a short side of circuit board 2, and second side 2b is a long side of circuit board 2. First side 2a and second side 2b are adjacent and perpendicular to each other. First antenna 21 is located in the middle of first side 2a, and second antenna 22 is located in the middle of second side 2b. This middle position refers to a region midway between two opposing sides, not just the midpoint of a side. The middle positions of first antenna 21 and second antenna 22 between adjacent sides allow them to be spaced apart, preventing interference between them.

[0055] In other embodiments, the circuit board 2 may have other polygonal structures, for example, the circuit board 2 may have a pentagonal or hexagonal structure.

[0056] In other embodiments, the first antenna 21 and the second antenna 22 may also be interchanged, with the first antenna 21 being located on the second side 2b and the second antenna 22 being located on the first side 2a. The first antenna 21 and the second antenna 22 may also be arranged relatively far apart to avoid interference between the first antenna 21 and the second antenna 22.

[0057] In this embodiment, a display screen 12 is also provided on the side of the housing 1, and the display screen 12 is electrically connected to the circuit board 2, wherein the processor 23 is electrically connected to the display screen 12 and the button 13, and the display screen 12 is used to display the operation menu and detection information, such as displaying the food temperature information collected by the wireless probe 200.

[0058] In the projection direction perpendicular to display screen 12, a portion of circuit board 2 is located within the projection area of ​​display screen 12, while the remaining portion of circuit board 2 is located outside of the projection area. The portion of circuit board 2 between first antenna 21 and second antenna 22 is located within the projection area of ​​display screen 12, ensuring sufficient spacing between first antenna 21 and second antenna 22 to prevent mutual interference. For example, first antenna 21 is located within the projection area of ​​display screen 12, while second antenna 22 is located outside of the projection area of ​​display screen 12. Using display screen 12 as a reference, first antenna 21 and second antenna 22 are relatively far apart to prevent mutual interference.

[0059] In other embodiments, the display screen 12 may also be disposed at other locations of the housing 1 . For example, when the top area of ​​the housing 1 is relatively large, the display screen 12 may also be disposed at the top of the housing 1 .

[0060] In this embodiment, the first antenna 21 and the second antenna 22 both include a main body and a connecting portion. The main body has a relatively larger area for sending and receiving signals, and the connecting portion is a linear structure for connecting the main body and the circuit where the processor 23 is located. The main body of the first antenna 21 is close to or abuts the first side 2a, and the main body of the second antenna 22 is close to or abuts the second side 2b. The main body of the first antenna 21 and the main body of the second side 2b are relatively far apart and face different directions, so that the first antenna 21 and the second side 2b form different radiation directions. Figure 4 As shown, the radiation direction of the first antenna 21 is perpendicular to the first side 2a and spreads outward. The radiation direction of the second side 2b is perpendicular to the second side 2b and spreads outward. This arrangement allows the radiation directions of the first antenna 21 and the second antenna 22 to be in different directions, and the radiation directions of the first antenna 21 and the second antenna 22 are at a 90° angle. This effectively prevents the radiation directions of the first antenna 21 and the second antenna 22 from being close to each other, resulting in overlapping radiation areas and causing mutual interference.

[0061] In this embodiment, the antenna interconnecting the wireless probe base 100 and the wireless probe 200 and the antenna connected to the terminal are separately arranged to form two separate antennas, which can avoid the problem of large volume when the two antennas are combined together; the antenna is large in volume and has high manufacturing cost, and it emits multiple signals at the same time, and its heat is also more serious.

[0062] Since the first antenna 21 and the second antenna 22 in the wireless probe seat 100 are spaced apart and arranged on different sides of the circuit board 2, the first antenna 21 and the second antenna 22 are arranged far away from each other, which can reduce the mutual interference between the first antenna 21 and the second antenna 22, so that the first antenna 21 and the second antenna 22 can communicate stably and accurately respectively, thereby improving the user experience of the wireless probe device.

[0063] In one embodiment, the first antenna 21 and the second antenna 22 may also be located at other locations relatively far apart, so as to avoid mutual interference between the first antenna 21 and the second antenna 22 .

[0064] like Figure 6 As shown, the first antenna 21 is located at the end of the first side 2a away from the second side 2b, and the second antenna 22 is located at the end of the second side 2b away from the first side 2a. A longer distance is formed between the first antenna 21 and the second antenna 22 to better avoid mutual interference.

[0065] In other embodiments, the first antenna 21 is located at the end of the first side 2a away from the second side 2b, and the second antenna 22 is located in the middle of the second side 2b; or the first antenna 21 is located in the middle of the first side 2a, and the second antenna 22 is located at the end of the second side 2b away from the first side 2a. This also creates a relatively longer distance between the first antenna 21 and the second antenna 22, which can prevent mutual interference.

[0066] In one embodiment, the first antenna 21 and the second antenna 22 may be located on two non-adjacent sides of the circuit board 2 , which may also avoid mutual interference between the first antenna 21 and the second antenna 22 .

[0067] like Figure 7 As shown, circuit board 2 includes a first side 2a, a second side 2b, and a third side 2c. First side 2a is a short side of circuit board 2, while second side 2b and third side 2c are opposite long sides of circuit board 2. Second side 2b, first side 2a, and third side 2c are vertically connected in sequence, and first side 2a and third side 2c are non-adjacent sides. First antenna 21 is located on third side 2c, and second antenna 22 is located on second side 2b.

[0068] Among them, the first antenna 21 can be located in the middle of the third side 2c, and the second antenna 22 is located in the middle of the second side 2b. The radiation angle of the first antenna 21 and the radiation angle of the second antenna 22 are greater than 90°. If the first antenna 21 and the second antenna 22 are located on a straight line parallel to the first side 2a, the radiation angle of the first antenna 21 and the radiation angle of the second antenna 22 are 180°.

[0069] In other embodiments, the first antenna 21 may be located at the end of the third side 2c, and the second antenna 22 may be located at the end of the second side 2b away from the first antenna 21. A longer interval may be formed between the first antenna 21 and the second antenna 22, which may better avoid mutual interference.

[0070] In other embodiments, the first antenna 21 and the second antenna 22 may also be located on two other non-adjacent sides of the circuit board 2 .

[0071] In one embodiment, the distance between the first antenna 21 and the second antenna 22 is greater than 3 cm. For example, the distance between the first antenna 21 and the second antenna 22 is 5 cm. This can ensure that the first antenna 21 and the second antenna 22 are set away from each other, thereby avoiding mutual interference between the first antenna 21 and the second antenna 22.

[0072] In one embodiment, the signal frequency ranges of the first antenna 21 and the second antenna 22 do not overlap, which can further avoid mutual interference between the first antenna 21 and the second antenna 22.

[0073] The signal frequency of the first antenna 21 is less than 1 GHz, and the signal frequency of the second antenna 22 is greater than 1 GHz. The signal frequency ranges of the first antenna 21 and the second antenna 22 are staggered.

[0074] For example, the signal frequency of the first antenna 21 is selected as 915 MHZ, and the signal frequency of the second antenna 22 is selected as 2.4 GHZ. The first antenna 21 and the second antenna 22 use different signal frequencies to send and receive signals, which can further avoid mutual interference between the first antenna 21 and the second antenna 22, and improve the communication stability and accuracy of the first antenna 21 and the second antenna 22.

[0075] Please refer to Figure 3 and Figure 8 In one embodiment, the housing 1 is further provided with a button 13 and a charging port 14, which are electrically connected to the circuit board 2, respectively. The processor 23 is electrically connected to the button 13, and the button 13 is used to operate the function menu on the display screen 12 to wirelessly operate the temperature acquisition of the wireless probe 200, and can also be used to operate the communication connection with the terminal 300. The charging port 14 is used to charge the wireless probe base and can also have a data transmission function, which can realize a wired communication connection with the terminal 300.

[0076] In one embodiment, in the projection direction of the display screen 12, part of the circuit board 2 is located in the projection area of the display screen 12, and the other part of the circuit board 2 is located outside the projection area of the display screen 12. Among them, the first antenna 21 is located in the projection area of the display screen 12, and the second antenna 22 is located outside the projection area of the display screen 12. The display screen 12 is taken as a reference object, and the first antenna 21 and the second antenna 22 form a relatively far interval to avoid mutual interference between the first antenna 21 and the second antenna 22.

[0077] In other embodiments, the first antenna 21 and the second antenna 22 are located outside the projection area of the display screen 12, and the first antenna 21 and the second antenna 22 are respectively located on both sides of the projection area of the display screen 12. The first antenna 21 and the second antenna 22 can also form a relatively far interval to avoid mutual interference between the first antenna 21 and the second antenna 22.

[0078] Please refer to Figure 1 , Figure 2 and Figure 9 In one embodiment, a wireless probe device is provided, which includes a wireless probe 200 and a wireless probe base 100 in any of the above embodiments.

[0079] In this embodiment, the wireless probe 200 is provided with a temperature sensor 201 and a third antenna 202. When the wireless probe 200 is inserted into food, the temperature sensor 201 can collect and detect the temperature of the food and obtain a food temperature signal. The wireless probe 200 can wirelessly transmit the food temperature signal through the third antenna 202.

[0080] The third antenna 202 of the wireless probe 200 is adapted with the first antenna 21 of the wireless probe base 100 and communicates at the same frequency. The first antenna 21 of the wireless probe base 100 is used to receive the food temperature signal transmitted by the third antenna 202.

[0081] The second antenna 22 of the wireless probe base 100 is adapted with the fourth antenna 301 in the terminal 300 and communicates at the same frequency. The second antenna 22 of the wireless probe base 100 is used to transmit the food temperature signal to the terminal 300, and the fourth antenna 301 in the terminal 300 is used to receive the food temperature signal transmitted by the second antenna 22.

[0082] In this embodiment, since the first antenna 21 and the second antenna 22 in the wireless probe seat 100 are spaced apart and arranged on different sides of the circuit board 2, the first antenna 21 and the second antenna 22 are arranged far away from each other, which can reduce the mutual interference between the first antenna 21 and the third antenna 202 when communicating and the second antenna 22 and the fourth antenna 301 when communicating, so that the first antenna 21 and the third antenna 202 can communicate and the second antenna 22 and the fourth antenna 301 can communicate stably and accurately respectively, thereby improving the user experience of the wireless probe device.

[0083] In one embodiment, a cooking equipment accessory is provided. The difference between this cooking equipment accessory and the above-mentioned wireless probe base is that the cooking equipment accessory can communicate not only with the wireless probe, but also with cooking equipment such as ovens, microwave ovens, and air fryers.

[0084] The cooking device accessory in this embodiment includes the aforementioned housing 1 and circuit board 2, as well as the aforementioned first antenna 21 and second antenna 22 and their layout.

[0085] In this embodiment, the first antenna 21 of the cooking device accessory can be used to wirelessly communicate with one or more cooking devices such as a wireless probe, oven, microwave oven, and air fryer. The second antenna 22 of the cooking device accessory can be used to wirelessly communicate with one or more terminals such as a mobile phone, tablet, and laptop computer. In other words, the first antenna 21 of the cooking device accessory can connect to other cooking devices through the Internet of Things, while the second antenna 22 of the cooking device accessory can connect to the terminal through the Internet.

[0086] The cooking device accessory of this embodiment is equipped with a first antenna 21 and a second antenna 22. The antenna connected to the cooking device and the antenna connected to the terminal are separated into two separate antennas. This avoids the bulk of the two antennas, which would be expensive to manufacture and would generate more heat if multiple signals were transmitted simultaneously. The first and second antennas 21, 22 are positioned separately from each other to prevent signal interference between them.

[0087] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
