Description

Technical Field

[0001] This utility model relates to the field of thermometer structure, and in particular to a multifunctional foldable food thermometer. Background Technology

[0002] In the existing technology, foldable food thermometers have been widely used in daily food temperature detection scenarios. These thermometers are usually equipped with a probe for detecting temperature, and the probe can rotate relative to the thermometer shell. By setting up a corresponding transmission structure, the probe can be unfolded and folded, so that the thermometer can reduce the space occupied when not in use, making it convenient to store and carry, and meeting the basic usage needs of users in different scenarios.

[0003] However, existing foldable food thermometers have obvious shortcomings in practical applications. After the temperature probe is unfolded, it often lacks an effective limiting and fixing structure and cannot be stably maintained in the preset operating position. When measuring food temperature, it is easy to swing randomly due to external force or its own structural design defects, which makes it inconvenient for operators to hold and use, and may also affect the accuracy of temperature measurement. Utility Model Content

[0004] In view of the shortcomings mentioned above in the background technology, this utility model provides a multifunctional foldable food thermometer.

[0005] The present invention adopts the following technical solution: A multifunctional foldable food thermometer, comprising: The outer casing has a clearance notch at one end; A turntable is fitted into the clearance notch and can rotate relative to the outer shell. A temperature probe is fixedly provided on one side of the turntable for temperature detection. The sprocket is axially fixed and restricted to rotating inside the housing. The sprocket is connected to the turntable for transmission. A chain groove is provided in the half-circumference area of ​​the sprocket ring surface, and the two sides of the sprocket corresponding to the chain groove area are mutually parallel limiting planes. A transmission component is disposed inside the housing and is restricted to slide linearly relative to the sprocket. The transmission component is provided with a row of slotted posts, which are successively embedded in the chain groove of the sprocket to drive the sprocket to rotate. A spring arm is fixedly provided at one end of the transmission component along its moving direction, and the spring arm is provided with a protruding latch. A limiting component is fixedly installed inside the outer shell, and a row of slots is provided on the limiting component; When the temperature probe is attached to one side of the outer shell, it pushes the transmission component to move. The grooved pins on the transmission component are inserted one by one into the chain groove of the sprocket and push the sprocket to rotate. When the sprocket rotates to 180°, the turntable rotates synchronously with the sprocket, so that the temperature probe rotates from the attached state to extend in a straight line from the end of the outer shell. At this time, the limiting plane of the sprocket is attached to the surface of the transmission component. The movement of the transmission component synchronously drives the elastic arm to move, so that the tenon on the elastic arm is embedded in the groove of the limiting component.

[0006] In one possible implementation, the outer shell includes an upper shell and a lower shell, a first column is provided on the lower shell, a second column is provided on the upper shell, and a first through hole is provided at the center of the turntable; when the upper shell and the lower shell are attached and fixed, the second column and the first column form a shaft hole fit, and the first through hole is fitted into the outside of the first column in a clearance fit manner.

[0007] In one possible implementation, the outer shell includes an upper shell and a lower shell, a first column is provided on the lower shell, a second column is provided on the upper shell, and a second through hole is provided at the center of the sprocket; when the upper shell and the lower shell are fitted and fixed together, the second column and the first column form a shaft hole fit, and the second through hole is fitted into the outside of the first column in a clearance fit manner.

[0008] In one possible implementation, the thermometer further includes an actuating element with a boss on one side. A clearance hole is formed on the surface of the housing facing away from the temperature probe. The boss is fitted and fixed to the transmission element, so that the boss is embedded in the clearance hole. The size of the boss is smaller than the size of the actuating element and the transmission element, so that the boss is restricted to sliding within the clearance hole, and the transmission element is restricted to sliding linearly relative to the sprocket along the extension direction of the clearance hole.

[0009] In one possible implementation, the actuating member has two latching arms on the surface of the boss, and the ends of the two latching arms are respectively provided with protruding latching heads on the side opposite to the middle of the actuating member; the transmission member has two through slots, and the two latching arms are respectively inserted into the two through slots, so that the two latching heads form a latching engagement with the side surface of the transmission member near the groove post, so as to limit and fix the boss on the transmission member.

[0010] In one possible implementation, the transmission member has clearance notches on one side near the inner wall of the housing and opposite to both sides of the housing, and the limiting member corresponds to the position of the clearance notch; when the transmission member moves, the clearance notch can pass through the limiting member as the transmission member moves.

[0011] In one possible implementation, an ultraviolet lamp is also provided on the back of the housing, which is used to perform mold detection by irradiation.

[0012] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: When the transmission component drives the sprocket to rotate forward or backward by 180°, the limiting plane of the sprocket can be closely attached to the surface of the transmission component, so that the temperature probe is kept in a parallel extended or folded state relative to the outer shell. When the temperature probe is extended, it maintains a straight extension state relative to the outer shell, which is convenient for holding the outer shell for operation. It can also effectively avoid the inconvenience of operation or detection deviation caused by the random swinging of the temperature probe during the detection process, thereby enhancing the reliability and user experience of the food thermometer.

[0026] To make the purpose, technical solution and advantages of this utility model clearer, the present utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this embodiment, unless otherwise stated, "a plurality of" means two or more.

[0028] Furthermore, in this embodiment, directional terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used to describe and clarify relative positions, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0029] This utility model provides a multifunctional foldable food thermometer, as shown in the attached figure. Figures 1 to 4 As shown, the thermometer includes a housing 1, a turntable 2, a sprocket 3, a transmission component 4, a limiting component 5, and a lever component 6. One end of the housing 1 has a clearance notch 101. A temperature probe 7 for temperature detection is fixed to one side of the turntable 2. The turntable 2 is fitted into the clearance notch 101 and rotates relative to the housing 1. The housing 1 consists of an upper housing 11 and a lower housing 12. The upper housing 11 and lower housing 12 are fitted together by a snap-fit ​​or screw-fitting method to house the sprocket 3, transmission component 4, and lever component 6 inside the housing 1. Simultaneously, the sprocket 3, transmission component 4, and lever component 6 work together to drive the turntable 2 to rotate 180° clockwise and counterclockwise, achieving stable deployment and reliable retraction of the temperature probe 7, effectively ensuring the operational flexibility of the thermometer during use. Preferably, a receiving groove 103 is provided on the side of the housing 1 facing the temperature probe 7. When the temperature probe 7 is retracted to fit against the housing 1, it fits precisely into the receiving groove 103.

[0030] The front of the outer casing 1 features control keys and a display screen, while the back houses an ultraviolet lamp 8. This ultraviolet lamp 8 detects mold through irradiation. The detection principle is that ultraviolet light excites fluorescent substances in mold spores and their metabolic products, causing these substances to emit fluorescence at specific wavelengths. Operators can quickly determine the presence of mold on the surface of the item by observing whether corresponding fluorescence appears in the irradiated area. Inside the outer casing 1, a circuit board and supporting electronic components are also installed. The circuit board is securely mounted inside the casing 1 using snap-fit ​​connections or fasteners. A battery and orderly arranged electronic components are soldered onto the circuit board. The battery forms a reliable electrical connection with the temperature probe 7 and the ultraviolet lamp 8, providing a stable power supply for their operation. This structural design not only ensures the reliability of the assembly of each component and the stability of the electrical connection but also makes the entire thermometer compact. In addition to its temperature detection function, the newly added mold detection function is easy to operate, further expanding the thermometer's application scenarios and practicality.

[0031] In addition, a connecting post 21 is provided on one side of the turntable 2. The temperature probe 7 is inserted into the connecting post 21 and fixed by a threaded connection. A wire hole 202 is provided on the surface of the turntable 2 at the position corresponding to the axis of the connecting post 21. The axis of the wire hole 202 is perpendicular to the axis of the connecting post 21, and the wire hole 202 is connected to the inside of the connecting post 21. The wire connected to the temperature probe 7 passes through the wire hole 202 inside the connecting post 21 and is connected to the circuit board. Sufficient length is reserved for the wire of the temperature probe 7 to avoid affecting the connection between the temperature probe 7 and the circuit board when the turntable 2 rotates.

[0032] As attached Figure 3 and 6 As shown, a first through hole 201 is provided in the center of the turntable 2, a first column 131 is provided on the lower housing 12, and a second column 132 is provided on the upper housing 11. When assembling the turntable 2, the first through hole 201 is fitted into the outside of the first column 131 by means of clearance fit. After the upper housing 11 and the lower housing 12 are fitted and fixed, the second column 132 and the first column 131 form a reliable shaft hole fit and achieve precise positioning, so that the first through hole 201 is always fitted into the outside of the first column 131, thereby restricting the turntable 2 to rotate only around the first column 131 as the rotation axis.

[0033] Continue to refer to the appendix Figure 3 and 6The sprocket 3 is also axially fixed and restricted to rotation within the housing 1. Specifically, the restrictive structure consists of a third column 141 on the lower housing 12 and a fourth column 142 on the upper housing 11. A second through hole 301 is located at the center of the sprocket 3. During assembly, the second through hole 301 is fitted into the outer side of the third column 141 with a clearance fit. After the upper housing 11 and lower housing 12 are fitted and fixed together, the fourth column 142 and the third column 141 form a reliable shaft-hole fit, ensuring that the second through hole 301 remains fitted into the outer side of the third column 141. This restricts the sprocket 3 to rotate only around the third column 141 as its axis of rotation.

[0034] As attached Figure 7 As shown, the sprocket 3 has chain grooves 302 only in the half-circumference area, and the sprocket 3 forms mutually parallel limiting planes 31 on both sides of the area where the chain grooves 302 are located. The sprocket 3 and the turntable 2 achieve a reliable transmission connection, and the specific transmission connection structure is shown in the attached diagram. Figure 3 and 6 As shown, a first transmission wheel 91 is fixedly mounted on the end face of the turntable 2, and a second transmission wheel 92 is fixedly mounted on the end face of the sprocket 3. The first transmission wheel 91 and the second transmission wheel 92 form a stable transmission connection through the winding of the transmission belt 93. Specifically, the first transmission wheel 91 and the second transmission wheel 92 can adopt a synchronous pulley structure, and the transmission belt 93 is adapted to be a synchronous belt. This transmission connection method can ensure the transmission accuracy and synchronization between the sprocket 3 and the turntable 2, making the entire transmission run smoothly and providing a reliable power transmission guarantee for the unfolding and retracting action of the temperature probe 7. Preferably, both the first transmission wheel 91 and the second transmission wheel 92 can be embedded with bearings, which are sleeved on the second column 132 or the fourth column 142, restricting the turntable 2 and the sprocket 3 while improving their rotation smoothness.

[0035] As attached Figure 8As shown, a row of slotted posts 41 is arranged on one side of the transmission component 4, with the slotted posts 41 located on the side of the transmission component 4 facing the sprocket 3. The transmission component 4 is assembled inside the housing 1 and is restricted to sliding linearly relative to the sprocket 3. When the transmission component 4 moves, the slotted posts 41 are successively embedded in the chain groove 302 of the sprocket 3, thereby stably driving the sprocket 3 to rotate. At the same time, the transmission component 4 has a relief groove 403 on the side where the slotted posts 41 are located, which can avoid the end of the limiting plane 31 of the sprocket 3. Specifically, when a row of slotted posts 41 pushes the sprocket 3 to rotate, the first slotted post 41 moves into the chain groove 301 and pushes the sprocket 3 to rotate, causing the limiting plane 31 of the sprocket 3 to rotate into the relief groove 403. After the last slotted post 41 pushes the sprocket 3 away from the chain groove 301, the sprocket 3 rotates until the limiting plane 31 is parallel to and fits against the surface of one end of the relief groove 403 of the transmission component 4. At this time, the sprocket 3 can be restricted from continuing to rotate, thereby restricting the turntable 2 to remain fixed, and thus restricting the temperature probe 7 to remain in a folded or fully unfolded state.

[0036] The sliding limitation of the transmission component 4 is achieved through its connection with the actuating component 6, as detailed in the attached figure. Figures 9 to 12 As shown, a boss 61 is provided on one side of the actuating member 6, and a clearance hole 102 is provided on the surface of the outer shell 1 facing away from the temperature probe 7. The boss 61 is fitted into the clearance hole 102 outside the outer shell 1, and the boss 61 is fitted and fixed to the transmission member 4 by a snap-fit ​​engagement, so that the boss 61 is fitted into the clearance hole 102 and can slide along both ends of the outer shell 1. Furthermore, the size of the boss 61 is smaller than the size of the actuating member 6 and the transmission member 4, so as to reliably restrict the boss 61 to slide within the clearance hole 102, while limiting the transmission member 4 to slide linearly relative to the sprocket 3 along the extension direction of the clearance hole 102. This structural design achieves precise guidance for the linear sliding of the transmission member 4, ensuring stable engagement between the groove post 41 and the chain groove 302 and reliable transmission.

[0037] Continue to refer to the appendix Figure 7 and 8The snap-fit ​​structure between the boss 61 and the transmission component 4 is as follows: Two snap-fit ​​arms 62 are symmetrically arranged on the surface of the boss 61, and each snap-fit ​​arm 62 has a protruding snap-fit ​​head 621 at its end on the side facing away from the center of the actuating component 6. Two through slots 401 are formed on the transmission component 4 corresponding to the positions of the two snap-fit ​​arms 62. When assembling the transmission component 4 and the actuating component 6, the two snap-fit ​​arms 62 are aligned with the two through slots 401 and inserted until the two snap-fit ​​heads 621 are completely inserted through the slots 401, so that the two snap-fit ​​arms 62 are inserted into the two through slots 401. Simultaneously, the two snap-fit ​​heads 621 form a stable snap-fit ​​with the surface of the transmission component 4 near the recessed post 41, thereby firmly fixing the boss 61 to the transmission component 4. This snap-fit ​​structure is simple and compact, and the assembly process is convenient and efficient. It achieves a reliable connection between the boss 61 and the transmission component 4 without the need for additional fasteners, and the structure is stable and not easily loosened after connection.

[0038] Please refer to the appendix. Figure 5 , 8 In the transmission component 4, a spring arm 42 is fixedly mounted at one end along its moving direction. The spring arm 42 has a protruding latch 421. A row of slots 501 are provided on the limiting component 5. The limiting component 5 is fixedly installed inside the outer shell 1. Specifically, the limiting component 5 can be integrally formed with the lower shell 12 or the upper shell 11. The transmission component 4 has clearance notches 402 on the side near the inner wall of the outer shell 1 and on both sides of the outer shell 1. The limiting component 5 is arranged in the moving path of the clearance notches 402.

[0039] When the transmission component 4 moves, the clearance notch 402 moves synchronously with the transmission component 4, passing through the limiting component 5 to achieve effective clearance. At the same time, the movement of the transmission component 4 causes the elastic arm 42 to swing elastically, allowing the tenon 421 to smoothly pass through each slot 501 of the limiting component 5 and engage sequentially, forming an angle-stopping structure. This structure does not completely fix the turntable 2, but uses the elasticity of the elastic arm 42 to embed the tenon 421 into the slot 501, thereby limiting the movement of the transmission component 4 in a step-like manner. This, in turn, limits the angle of rotation of the turntable 2 and the temperature probe 7 in a step-like manner. It can accurately control the dwell angle of the temperature probe 7 during the unfolding and folding process, and also provide clear gear feedback during operation, further improving the accuracy and convenience of operation.

[0040] As attached Figure 1 and 4As shown, in its retracted state, the temperature probe 7 fits snugly against the receiving groove 103 on one side of the outer casing 1. When using the temperature probe 7, the operator pushes the actuating member 6 on the outside of the outer casing 1 along the clearance hole 102. The actuating member 6 drives the transmission member 4 to slide synchronously inside the outer casing 1. During the sliding process, the grooved posts 41 on the transmission member 4 can accurately embed one by one into the chain groove 302 of the sprocket 3, and the sprocket 3 is stably driven to rotate through the interlocking action. The turntable 2, which is connected to the sprocket 3, rotates synchronously, so that the temperature probe 7 can smoothly rotate and unfold from its retracted state against the outer casing 1. When the sprocket 3 rotates to 180°, the temperature probe 7 rotates to the working state where it extends straight outward from the end of the outer casing 1. This unfolded form allows the operator to directly hold the outer casing 1 and insert the temperature probe 7 into the item to be tested, efficiently completing the temperature detection. Simultaneously, when the sprocket 3 rotates to its 180° limit position, the limiting plane 31 of the sprocket 3 is in contact with the surface of the transmission component 4, keeping the temperature probe 7 in a straight line relative to the outer casing 1. At the same time, the movement of the transmission component 4 synchronously drives the elastic arm 42 to move synchronously, causing the latch 421 on the elastic arm 42 to precisely engage within the slot 501 of the limiting component 5, forming a reliable positioning structure after the turntable 2 has rotated into position. This positioning structure effectively prevents the temperature probe 7 from swinging arbitrarily during the detection process, ensuring the accuracy of the temperature detection data and the stability of the operation.

[0041] In summary, this utility model integrates core components such as the turntable 2, sprocket 3, transmission component 4, and actuating component 6, along with supporting circuit elements, within the outer casing 1. These components work collaboratively through transmission. Both the turntable 2 and sprocket 3 are confined to rotation within the outer casing 1, forming a transmission connection. The transmission component 4, through its connection with the actuating component 6 and the guidance of the clearance hole 102, achieves smooth sliding. The grooved post 41 of the transmission component 4 engages with the chain groove 302 of the sprocket 3, driving the turntable 2 to complete a 180° reciprocating rotation, thus enabling the temperature probe 7 to fold and unfold. After the temperature probe 7 is fully folded and unfolded, the limiting plane 31 of the wheel 3 and the two sides of the clearance groove 403 of the transmission component 4 are in contact, preventing rotation. Simultaneously, the engagement of the latch 421 of the elastic arm 42 with the latch 501 of the limiting component 5 further ensures the stability of the rotation angle of the temperature probe 7 after unfolding, effectively preventing swaying during detection. The ultraviolet lamp 8 integrated in the outer shell 1 achieves rapid mold detection through the principle of fluorescence excitation. Combined with control keys and a display screen, it makes operation more convenient. The entire device has a compact structure and stable operation, which not only ensures the accuracy of temperature detection and the multi-functionality of mold detection, but also significantly improves the flexibility of operation and effectively expands the application scenarios.

[0042] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using the concept of this utility model shall be considered as an infringement of the protection scope of this utility model.
