[0029] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods.

This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0030] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0031] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning.

For example, "A and B are parallel" means that A and B are parallel or approximately parallel, with the angle between A and B ranging from 0° to 10°. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, with the angle between A and B ranging from 80° to 100°. The directional terms used in the embodiments of this application, such as "upper," "inner," "outer," and "side," are merely for reference to the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0033] This application provides a handheld food thermometer, a portable tool for detecting food temperature. The handheld food thermometer contains replaceable parts, such as a disposable battery. It also requires a high degree of sealing, as it may need to detect the temperature of broth or liquids. To prevent liquids and dust from entering the handheld temperature probe, a high degree of sealing is required. Furthermore, the battery is installed in the recessed cavity of the handheld food thermometer and needs to be replaced when the battery is depleted. Therefore, the handheld temperature probe needs to be disassembled and reassembled.

[0034] Please refer to Figure 1-3 The handheld food thermometer includes a main body 1 and a probe 2. One end of the probe 2 is a pointed tip for inserting into food to detect its temperature, and the other end of the probe 2 is connected to the main body 1. The main body 1 includes a housing 10 and a cover 20. The housing 10 can be used to install various parts; specifically, the probe 2 is mounted on the housing 10. The housing 10 has a mounting surface 11, on which a recessed cavity 12 is provided. The recessed cavity 12 is used to install parts that need to be sealed, such as batteries or circuit boards. The recessed cavity 12 has an opening 121 on the mounting surface 11. The opening 121 allows the user to install parts into or remove parts from the recessed cavity 12; that is, the opening 121 allows the user to replace parts inside the recessed cavity 12. The cover 20 covers the mounting surface 11 and seals the opening 121.

[0035] like Figure 2 and Figure 3The housing 10 is provided with a first latching portion 13. In one embodiment, there are multiple first latching portions 13, which are arranged at intervals along the second direction X. The cover 20 is provided with a second latching portion 21. In one embodiment, there are multiple second latching portions 21, which are arranged at intervals along the second direction X. The second latching portions 21 can be latched to the corresponding first latching portions 13, so that the housing 10 and the cover 20 are detachably connected. The second latching portions 21 and the first latching portions 13 can be connected by relative sliding latching.

[0036] In one embodiment, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the housing 10 and the cover 20 have a latched state and an unlatched state. The cover 20 can slide reciprocally relative to the housing 10 in a second direction X to switch between the latched and unlatched states of the housing 10 and the cover 20. Figure 1 and Figure 2 In the latched state, the first latching part 13 and the second latching part 21 are latched together, and their projections on the assembly surface 11 at least partially overlap. Specifically, in the latched state, a portion of the structure of the first latching part 13 is located on the side of the portion of the structure of the second latching part 21 away from the assembly surface 11, so that the housing 10 and the cover 20 are relatively locked in the first direction Z, that is, the housing 10 and the cover 20 are mutually limited in the first direction Z. The second direction X is perpendicular to the first direction Z. In one embodiment, the second direction X is parallel to the assembly surface 11 and is the length direction of the housing 10. The first direction Z is perpendicular to the assembly surface 11 and is the thickness direction of the housing 10.

[0037] When the buckle is released, such as Figure 4 and Figure 5 As shown, the first latching part 13 and the second latching part 21 are separated, and their projections on the assembly surface 11 are misaligned, allowing the cover 20 and the housing 10 to move relative to each other in the first direction Z, so that the user can remove the cover 20 from the housing 10. When it is necessary to remove the cover 20, the cover 20 can be slid relative to the housing 10, causing the first latching part 13 and the second latching part 21 to separate, allowing the cover 20 to be removed from the housing 10. When reinstalling the cover 20, the cover 20 can be slid in the opposite direction relative to the housing 10, causing the first latching part 13 and the second latching part 21 to snap together, thereby securing the cover 20 and the housing 10.

[0038] The housing 10 and cover 20 of the handheld food thermometer of this application are slidably connected by a first latching part 13 and a second latching part 21. This slidable latching connection simplifies the assembly and disassembly of the housing 10 and cover 20. Users can switch between the latched and unlatched states of the housing 10 and cover 20 simply by sliding the cover 20, eliminating the need for tools and providing convenience. Furthermore, by using a sliding latching and unlatching mechanism, the latching and unlatching process of the cover 20 and housing 10 is more effortless than a pressing-type latching mechanism, improving the user experience.

[0039] In one embodiment, the handheld food thermometer further includes a seal 30 disposed between the mounting surface 11 and the cover 20. Preferably, the seal 30 is connected to the mounting surface 11, and the side of the seal 30 facing the cover 20 abuts against the cover 20. The seal 30 is disposed around the opening 121 so that the cover 20, the seal 30, the mounting surface 11, and the recessed cavity 12 cooperate to form a sealed space, thereby allowing the parts within the recessed cavity 12 to be located within the sealed space.

[0040] The handheld food thermometer of this application features a sealing element 30 surrounding the opening 121 of the recessed cavity 12. When the cover 20 is placed on the housing 10, the cover 20, sealing element 30, mounting surface 11, and recessed cavity 12 cooperate to form a sealed space, preventing liquids or dust from entering the recessed cavity 12. This meets the requirement of a high waterproof and dustproof rating for handheld food thermometers. Furthermore, the housing 10 and cover 20 are connected by a first snap-fit ​​part 13 and a second snap-fit ​​part 21. This snap-fit ​​connection simplifies the assembly and disassembly of the housing 10 and cover 20, eliminating the need for tools and providing convenience. Therefore, the handheld food thermometer of this application, while ensuring the sealing requirements of the housing 10 and cover 20, makes their assembly and disassembly even easier.

[0041] Since the sealing element 30 is located between the cover 20 and the housing 10, the sliding between the cover 20 and the housing 10 has a certain frictional resistance. Therefore, the cover 20 and the housing 10 do not easily slide relative to each other in their natural state. The cover 20 and the housing 10 need to be manually driven to slide relative to each other, thereby ensuring the stability of the cover 20 and the housing 10 in the snap-fit ​​state.

[0042] Furthermore, in one embodiment, there are multiple first latching portions 13 and multiple second latching portions 21, and each pair of first latching portions 13 and second latching portions 21 engages at one latching point. On the one hand, increasing the number of latching points can make the connection between the housing 10 and the cover 20 more stable. On the other hand, the multiple latching points can be relatively arranged at multiple positions of the sealing member 30. When each latching point is tightened, each position of the sealing member 30 can be compressed to improve the sealing performance of the sealing member 30 at various points and improve the uniformity of the overall sealing performance of the sealing member 30.

[0043] In one embodiment, such as Figure 6 and Figure 7 As shown, one of the first latching part 13 and the second latching part 21 includes a slide 40, and the slide 40 has an insertion port 41 at one end in the second direction X. The other of the first latching part 13 and the second latching part 21 includes an insertion part 50. In the latched state, the insertion part 50 can pass through the insertion port 41 and be disposed in the slide 40. When the insertion part 50 is inserted into the slide 40, the slide 40 can limit the insertion part 50 in a direction perpendicular to the sliding direction of the insertion part 50, so that the cover 20 and the housing 10 are fastened together.

[0044] In one embodiment, the first latching portion 13 includes a first slide rail 131 and a first insertion portion 132 arranged sequentially along a first direction Z, wherein the first slide rail 131 is disposed near the mounting surface 11 relative to the first insertion portion 132; the second latching portion 21 includes a second insertion portion 211 and a second slide rail 212 arranged sequentially along the first direction Z, wherein the second insertion portion 211 is disposed near the mounting surface 11 relative to the second slide rail 212. In the latching state, the second insertion portion 211 is inserted into the first slide rail 131, and the first insertion portion 132 is inserted into the second slide rail 212. Thus, the first latching portion 13 and the second latching portion 21 can mutually limit each other to achieve a tight fastening connection.

[0045] In one embodiment, such as Figure 3 As shown, a groove 22 is provided on the side of the cover 20 away from the mounting surface 11. The number of grooves 22 can be one or at least two. The groove 22 can increase the friction of the cover surface, so that the user can slide and change it with less effort. Of course, a protrusion can also be provided on the side of the cover 20 away from the mounting surface 11 to change the friction of the cover surface.

[0046] In one embodiment, the housing 10 is further provided with a first protrusion 133, and the cover 20 is further provided with a second protrusion 23. The first protrusion 133 is located on the sliding path of the second protrusion 23. In the latched state, the second protrusion 23 is located on one side of the first protrusion 133 in the second direction X. In the unlatched state, the second protrusion 23 is located on the other side of the first protrusion 133 in the second direction X. The second direction X is the sliding direction of the cover 20. By providing the first protrusion 133 and the second protrusion 23, when the housing 10 and the cover 20 slide relative to each other, the collision of the first protrusion 133 and the second protrusion 23 can produce a sound and feel of latching or unlatching, improving the user experience.

[0047] In one embodiment, such as Figure 8 and Figure 9 As shown, a portion of a plurality of first latching parts 13 are arranged at intervals along the second direction X to form a first latching group 14, and another portion is arranged at intervals along the second direction X to form a second latching group 15; the first latching group 14 and the second latching group 15 are respectively disposed on opposite sides of the opening 121. Specifically, the first latching group 14 and the second latching group 15 are disposed opposite each other along a third direction Y, which is perpendicular to both the second direction X and the first direction Z.

[0048] A portion of the multiple second latching parts 21 are arranged at intervals along the second direction X to form a third latching group 24, and another portion is arranged at intervals along the second direction X to form a fourth latching group 25. The third latching group 24 and the fourth latching group 25 are respectively provided on opposite sides of the cover 20. Specifically, the third latching group 24 and the fourth latching group 25 are arranged opposite each other along the third direction Y. The third latching group 24 is latched to the first latching group 14, and the fourth latching group 25 is latched to the second latching group 15. By providing two sets of latching positions on opposite sides of the sealing member 30, the sealing performance of the sealing member 30 in all directions can be made more consistent. Preferably, the latching positions on opposite sides of the sealing member 30 are symmetrically arranged, making the sealing performance of the sealing member 30 more uniform.

[0049] In one embodiment, Figure 9 As shown, the housing 10 has a mounting groove 16 on the side facing the cover 20. The mounting groove 16 includes a side wall 161 and a bottom wall 162. The bottom wall 162 forms a mounting surface 11. A first latching portion is provided on each of the two opposite side walls 161 of the mounting groove 16. Preferably, a first latching group 14 and a second latching group 15 are respectively provided on the two opposite side walls 161 along the third direction Y. A third latching group 24 and a fourth latching group 25 are respectively provided on the two opposite sides of the cover 20 along the third direction Y. In the latched state, the cover 20 is positioned within the mounting groove 16. Preferably, the surface of the cover 20 away from the mounting surface 11 is flush with the opening of the mounting groove 16 away from the mounting surface 11, making the surface of the handheld food thermometer flatter.

[0050] Furthermore, the mounting groove 16 has a sidewall 161 at one end in the second direction X, meaning that one end of the mounting groove 16 in the second direction X is a closed end 163, and the other end of the mounting groove 16 in the second direction X does not have a sidewall 161, meaning that the other end of the mounting groove 16 in the second direction X is an open end 164. The second direction X is the sliding direction of the cover 20 relative to the housing 10. When the cover 20 slides toward the closed end 163, the cover 20 and the housing 10 are snapped together; when the cover 20 slides toward the open end 164, the cover 20 and the housing 10 are released from the snap-on connection. In one embodiment, one of the closed end 163 and the cover 20 has a plug-in portion 26, and the other has a plug-in interface 1631. The plug-in portion 26 is used to be inserted into the plug-in interface 1631 when in the snap-on state. Specifically, an insertion interface 1631 is provided on the side wall 161 of the closed end 163 of the mounting groove 16, and an insertion part 26 is provided on the cover 20. When the cover 20 slides toward the closed end 163, the insertion interface 1631 and the insertion part 26 are inserted; when the cover 20 slides away from the closed end 163, the insertion interface 1631 and the insertion part 26 are separated. By providing the insertion interface 1631 and the insertion part 26, the connection stability between the housing 10 and the cover 20 can be further improved. Furthermore, the insertion part 26 and the insertion interface 1631 can also play a role in the relative positioning of the cover 20 and the housing 10.

[0051] In one embodiment, such as Figure 10 As shown, the sealing element 30 has multiple protruding ridges 31 on the side facing the cover 20, and the protruding ridges 31 are used to abut against the cover 20. By providing protruding ridges 31 on the sealing element 30, the protruding ridges 31 can achieve the compression amount of the sealing element 30 under relatively small pressure, thereby ensuring the sealing continuity of the entire seal. In one embodiment, the protruding ridges 31 are annular structures, with multiple protruding ridges 31 nested sequentially, and adjacent protruding ridges 31 are spaced apart. By setting the protruding ridges 31 as annular structures, the sealing element 30 can be guaranteed to have strong sealing performance in all circumferential directions.

[0052] In one embodiment, such as Figure 9 As shown, an annular mounting groove 17 is provided on the mounting surface 11. The sealing element 30 is installed in the mounting groove 17, and one end of the sealing element 30 protrudes from the mounting groove 17 towards the cover 20 so that the protruding ridge 31 can abut against the cover 20. The sealing element 30 can be interference-fitted with the mounting groove 17 to facilitate the installation and replacement of the sealing element 30.

[0053] In one embodiment, the surface of the seal 30 is provided with a smooth coating, the coefficient of friction of which is less than 0.5. For example, a parylene layer may be provided on the surface of the seal 30. By providing a smooth coating on the surface of the seal 30, the sliding friction between the cover 20 and the housing 10 can be reduced, facilitating smooth sliding between the housing 10 and the cover 20.

[0054] The above examples illustrate this application only to aid in understanding the invention and are not intended to limit the scope of the application. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the concept of this application.
