Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and more particularly to a temperature sensing module and a kitchen appliance. Background Technology

[0002] A range hood, also known as a kitchen exhaust hood, is a kitchen appliance used to purify the kitchen environment. Installed above the gas stove, it can quickly remove the waste from the burner and the harmful fumes produced during cooking, expelling them outdoors, reducing pollution, and purifying the air.

[0003] With the increasing level of automation, existing range hoods are beginning to incorporate temperature sensing modules to monitor the concentration of cooking fumes and enable timely adjustments. These modules consist of a probe mechanism and external wiring. The probe mechanism communicates with the range hood's control unit via this wiring, detecting the temperature of the cooktop and transmitting it to the control unit. The control unit then adjusts the range hood's on / off status or operating mode based on the received temperature reading. However, due to the long communication distance between the control unit and the probe mechanism, external environmental interference significantly affects the accuracy of the temperature data received by the control unit, hindering accurate adjustments to the range hood's operating status. Specifically, the existing control unit, used for analyzing the temperature data from the temperature sensing module, suffers from long external wiring, resulting in a lag in the acquired temperature data and poor real-time performance and accuracy. In addition, the external connection is long, and the temperature data will be distorted during the transmission of the external connection. For example, if the temperature actually detected by the temperature sensing module is 20°C, after the transmission of the long external connection, the temperature detected by the control mechanism will be distorted to 25°C, 30°C, etc.

[0004] Furthermore, existing external wiring typically includes a power cord, a ground wire, and a communication cable for signal transmission. One end of each of these wires extends into the housing to communicate with the sensor mechanism, while the other end extends out of the housing to communicate with the range hood's control mechanism. This results in a large number of wires protruding from the housing, affecting the overall aesthetics of the range hood and negatively impacting the user's cooking experience. Additionally, existing temperature sensing modules usually include at least two sensor mechanisms, each with 3 to 4 wires. The sheer number of wires associated with at least two sensor mechanisms further exacerbates the negative impact on the user's cooking experience.

[0005] Therefore, there is an urgent need to design a new temperature sensing module and kitchen appliances to improve the above problems. Summary of the Invention

[0113] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings, not all of them.

[0114] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0115] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0116] In the description of this embodiment, the terms "upper," "lower," "left," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element 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 present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0117] Example 1

[0118] This embodiment provides a kitchen appliance, which can be a range hood 1000, an integrated stove, etc. This embodiment uses a range hood 1000 as an example for explanation. Figure 1 As shown, the range hood 1000 of this embodiment includes a range hood body 200 and an outer cover 300. An air inlet 3201 is provided on the outer cover 300. Under the action of the range hood body 200, waste from the burner 2000 and harmful fumes generated during cooking are sequentially discharged outdoors through the air inlet 3201, the outer cover 300, and the range hood body 200. Furthermore, the range hood 1000 also includes a temperature sensing module 100 and a microprocessor. The temperature sensing module 100 is disposed inside the outer cover 300 and is communicatively connected to the microprocessor. When the burner 2000 heats up during use, the temperature sensing module 100 detects the energy radiated by the burner 2000. The temperature sensing module 100 converts the detected temperature signal into an electrical signal and sends it to a signal amplification circuit and an analog-to-digital conversion circuit, which then transmits it to the microprocessor. The microprocessor sends control signals to other control modules based on the received signals. For example, when the temperature of the burner head 2000 is high, the temperature sensing module 100 detects a high temperature and generates an electrical signal, such as a high-level signal. After detecting this high-level signal, the microprocessor sends corresponding control signals to other control modules. The microprocessor can also send control signals to other control modules based on changes in the electrical signal. The microprocessor can also receive data signals from other sensors and combine these signals to calculate the actual temperature of the burner head 2000, improving temperature measurement accuracy. This embodiment does not limit the type of temperature sensing module 100; for example, it can be set as an active infrared temperature sensor or a passive infrared temperature sensor. An active infrared temperature sensor emits infrared light, which is reflected after contacting the object being measured and then received again by the active infrared temperature sensor, thus measuring the temperature of the object. The passive infrared temperature sensor works as follows: when the temperature of an object is above thermodynamic zero, it radiates infrared light into the surrounding environment. The passive infrared temperature sensor detects the infrared radiation energy of the object, thus detecting the temperature of the object. In addition to the two types mentioned above, any infrared temperature sensor capable of non-contact measurement of the temperature of the object being measured is within the protection scope of this invention.

[0119] like Figure 1 and Figure 2 As shown, the outer cover 300 of this embodiment includes an outer cover body 320 and a decorative panel 310. The decorative panel 310 is disposed on the outside of the outer cover body 320 to achieve the aesthetic appearance of the overall shape of the range hood 1000. As a preferred embodiment, the decorative panel 310 is detachably connected to the outer cover body 320, thereby enabling quick assembly and disassembly of the decorative panel 310 and the outer cover body 320, and facilitating a better cleaning effect for the decorative panel 310.

[0120] Existing temperature sensing modules include a probe mechanism and an external cable. The probe mechanism communicates with the range hood's control mechanism via the external cable. The probe mechanism detects the temperature of the cooktop and feeds it back to the control mechanism, which then adjusts the range hood's on / off state or operating mode based on the received temperature reading. However, due to the long communication distance between the control mechanism and the probe mechanism, external environmental interference significantly affects the accuracy of the temperature data received by the control mechanism, thus hindering accurate adjustment of the range hood's operating status. Specifically, the existing control mechanism, used for analyzing the temperature data detected by the temperature sensing module, suffers from a long external cable connection, resulting in a lag in the temperature data acquired by the control mechanism. This leads to poor real-time performance and accuracy of the temperature data obtained by the control mechanism. Furthermore, the long external cable causes data distortion during transmission. For example, if the actual temperature detected by the temperature sensing module is 20℃, after transmission over a long external cable, the temperature detected by the control mechanism may be distorted to 25℃, 30℃, etc.

[0121] To solve the above problems, such as Figures 2-4 As shown, the temperature sensing module 100 in this embodiment includes a housing 30, a probe mechanism 10, and a first circuit board 80. Both the probe mechanism 10 and the first circuit board 80 are housed within the housing 30. The probe mechanism 10 is communicatively connected to the first circuit board 80, and the first circuit board 80 is communicatively connected to the control mechanism of the range hood. Because both the probe mechanism 10 and the first circuit board 80 are housed within the housing 30, the communication distance between them is short. This allows the first circuit board 80 to quickly receive the temperature data detected by the probe mechanism 10, ensuring strong real-time performance. Furthermore, due to the short communication path, the temperature data is not distorted. Therefore, the first circuit board 80 can quickly receive accurate temperature data detected by the probe mechanism 10. The first circuit board 80 can then issue accurate control commands to the control mechanism of the range hood using this accurate and real-time temperature data, thereby achieving precise adjustment of the range hood's operating state. Since the control commands issued by the first circuit board 80 to the control mechanism of the range hood are in simple binary form, the control commands are less affected by longer communication paths, thus not affecting the precise control of the range hood.Figure 2 As shown, there are at least two probe mechanisms 10, each corresponding to a burner head 2000, and each probe mechanism 10 can only detect the temperature of its corresponding burner head 2000, avoiding the problem of inaccurate temperature detection of a single burner head 2000 caused by mutual interference between different burner heads 2000. In this embodiment, two probe mechanisms 10 are set to correspond to two burner heads 2000 in the range hood. Of course, in other embodiments, the probe mechanisms 10 can also be set to one, three, four or more, depending on the specific number of burner heads 2000 corresponding to the temperature sensing module 100.

[0122] Among them, such as Figure 2 and Figure 12 As shown, a light-transmitting opening 36 is provided on the housing 30, allowing the light emitted or received by the probe mechanism 10 to pass through. Furthermore, combined with... Figure 2 and Figure 12 The temperature sensing module 100 in this embodiment also includes a light filter component 60, which is disposed at the light-transmitting port 36. The light filter component 60 filters the received radiation energy, removes stray interference light, and then transmits the infrared radiation energy to the probe 11. The probe 11 is connected to a microprocessor, which performs corresponding processing based on the signal changes in the probe 11. The temperature sensing module 100 can achieve accurate temperature detection.

[0123] In existing technologies, some temperature sensing modules 100 are equipped with two probe mechanisms 10, each corresponding to a filter component 60, resulting in high costs for the temperature sensing module 100. To address this issue, such as... Figure 2 and Figure 12 As shown, the temperature sensing module 100 in this embodiment also includes a support member 20, and at least two probe mechanisms 10 are disposed on the support member 20. The light paths emitted or received by the at least two probe mechanisms 10 can both pass through the filter assembly 60. In this embodiment, the at least two probe mechanisms 10 can share a single filter assembly 60, realizing the function of detecting at least two furnace heads 20000 with a single light-transmitting port 36. The temperature sensing module 100 has a simple structure and low cost.

[0124] Furthermore, such as Figure 12 As shown, there are two probe mechanisms 10 in this embodiment. The center lines of the light paths emitted or received by the two probe mechanisms 10 are set at an angle. The intersection of the center lines of the two light paths is located on the side of the probe mechanism 10 close to the filter component 60, which can realize the detection of temperature over a large range.

[0125] like Figure 2As shown, the temperature sensing module 100 in this embodiment also includes a wire assembly 70. The probe mechanism 10 and the first circuit board 80 are communicatively connected through the wire assembly 70. Compared with network, Bluetooth, or infrared communication methods, the transmission method of the wire assembly 70 can ensure more stable and accurate temperature data transmission. The data transmission capability of the wire assembly 70 is less affected by vibrations generated by the operation of the range hood, enabling the temperature sensing module 100 to accurately detect in environments with high vibration. Specifically, the length of the wire assembly 70 in this embodiment is 10mm to 50mm. The shorter length of the wire assembly 70 can avoid delays or distortions in temperature data transmission. Figure 2 As shown, the wiring assembly 70 includes a power cord 71, a ground wire 72, and a communication connection line 73 for signal transmission. The power cord 71 provides adequate power to the probe mechanism 10. The ground wire 72 prevents short circuits in the temperature sensing module 100, avoiding damage during use and preventing fires caused by short circuits, thus ensuring user safety when using the range hood. The communication connection line 73 ensures stable transmission of temperature data. Furthermore, since the power cord 71, ground wire 72, and communication connection line 73 are independently configured, if one wire fails, only the damaged wire needs to be replaced, eliminating the need to replace all wires and effectively saving costs.

[0126] Furthermore, existing external wiring typically includes a power cord, a ground wire, and a communication cable for signal transmission. One end of each of these wires extends into the housing to communicate with the sensor mechanism, while the other end extends out of the housing to communicate with the range hood's control mechanism. This results in a large number of wires protruding from the housing, affecting the overall aesthetics of the range hood and negatively impacting the user's cooking experience. Additionally, existing temperature sensing modules usually include at least two sensor mechanisms, each with 3 to 4 wires. The sheer number of wires associated with at least two sensor mechanisms further exacerbates the negative impact on the user's cooking experience.

[0127] To solve the above problem, such as Figure 2 As shown, the temperature sensing module 100 also includes an external connecting wire 90. One end of the external connecting wire 90 extends into the housing 30 and is connected to the first circuit board 80. The other end of the external connecting wire 90 extends out of the housing 30 and is used to connect to the control mechanism of the range hood. In this embodiment, the external connecting wire 90 extending out of the housing 30 of the temperature sensing module 100 is only one, which ensures the overall aesthetics of the range hood and makes it easy for users to clean or store it, and also enhances the user's cooking experience.

[0128] Combination Figure 2 A brief explanation of the structure of the external connection 90 is provided, such as... Figure 2As shown, the housing 30 has a wire outlet hole 33. The external connecting wire 90 includes a wire body 91 and a sealing member 92 disposed on its outer periphery. The wire body 91 is communicatively connected to the probe mechanism 10 and the control mechanism respectively. The sealing member 92 is inserted into the wire outlet hole 33 and completely seals the wire outlet hole 33, thereby providing a sealing and oil-proof function for the inside of the temperature sensing module 100, preventing oil fumes from interfering with the detection of the probe mechanism 10, and preventing the first circuit board 80 from malfunctioning. As a preferred solution, such as Figure 2 As shown, the cable 91 includes a connecting wire 911, a main wire 912, and an outer sheath 913. The first circuit board 80, the connecting wire 911, the main wire 912, and the control mechanism of the range hood are connected in sequence to realize the communication connection between the first circuit board 80 and the control mechanism of the range hood. The outer sheath 913 covers the outer periphery of the main wire 912 to prevent short circuits in the cable 91 from causing fires or electric shocks to users. The outer sheath 913 can achieve a good protective effect on the main wire 912, prevent damage to the main wire 912, and improve the service life of the main wire 912.

[0129] Combination Figure 3 The structure of the probe mechanism 10 is described below, such as Figure 3 As shown, the probe mechanism 10 includes a second circuit board 12, a connector 13, and a probe 11. The connector 13 is disposed on the second circuit board 12 and electrically connected to the second circuit board 12. The connector 13 is electrically connected to the wire assembly 70. The probe 11 is disposed on the second circuit board 12 and is communicatively connected to the second circuit board 12, thereby achieving a better communication connection between the probe 11 and the first circuit board 80.

[0130] Specifically, such as Figure 3 As shown, the connector 13 includes multiple connector solder feet 131. The second circuit board 12 has soldering holes corresponding to the connector solder feet 131. The connector solder feet 131 are inserted into the corresponding soldering holes and soldered to the second circuit board 12. This ensures both the communication connection between the connector 13 and the second circuit board 12 and the structural stability of the connection between the connector 13 and the second circuit board 12, preventing the connector 13 from falling off the second circuit board 12 and ensuring the normal operation of the temperature sensing module 100.

[0131] Specifically, such as Figure 3As shown, the connector 13 also includes three third interfaces 132. Each third interface 132 corresponds to and is connected to a power line 71, ground line 72, and communication connection line 73. The third interfaces 132 facilitate communication and structural connections between the power line 71, ground line 72, and communication connection line 73 and the connector 13, allowing users to quickly connect and disconnect the power line 71, ground line 72, and communication connection line 73 from the connector 13. Furthermore, markings can be made at the corresponding third interfaces 132 to ensure quick matching of the power line 71, ground line 72, and communication connection line 73 to their respective interfaces, preventing incorrect connections and improving the assembly efficiency of the temperature sensing module 100, thus ensuring its normal operation.

[0132] like Figure 4 As shown, the first circuit board 80 includes a first circuit board body 81 and at least two first connectors 82 disposed thereon and electrically connected thereto. Each first connector 82 is communicatively connected to a corresponding probe mechanism 10 via a wire assembly 70, thereby enabling a good communication connection between the first circuit board 80 and the probe mechanism 10. Specifically, the first connector 82 includes a first interface 821, and a power line 71, a ground line 72, and a communication connection line 73 are respectively connected to the corresponding first interface 821, thereby enabling quick assembly and disassembly of the power line 71, ground line 72, and communication connection line 73 from the first connector 82. Furthermore, as... Figure 4 As shown, the first circuit board 80 also includes a second connector 83 disposed on and electrically connected to the first circuit board body 81. The second connector 83 is communicatively connected to the external connection line 90, thereby realizing the communicative connection between the external connection line 90 and the first circuit board 80. Specifically, as shown... Figure 4 As shown, the second connector 83 includes a second interface 831, which is detachably connected to the external connection 90, facilitating quick assembly and disassembly of the external connection 90 and the first circuit board 80, and facilitating quick maintenance of the external connection 90 and the first circuit board 80.

[0133] like Figure 2 As shown, the probe mechanism 10, the wire assembly 70, and the first circuit board 80 are all mounted on the support member 20, which is located in the housing 30. The support member 20 can provide stable support for the probe mechanism 10, the wire assembly 70, and the first circuit board 80, preventing them from shaking in the housing 30 and ensuring the accurate detection effect of the temperature sensing module 100.

[0134] like Figure 47As shown, the housing 30 includes an outer shell 31 and a cover 32. The outer shell 31 forms a receiving cavity 311 with a first opening 312. The cover 32 blocks the first opening 312 and is detachably connected to the outer shell 31. When the outer shell 31 and the cover 32 are locked, the outer shell 31 and the cover 32 can form a sealed environment to prevent oil fumes from outside the temperature sensing module 100 from entering the housing 30, to prevent oil fumes from interfering with the detection of the probe mechanism 10, and to prevent the first circuit board 80 from malfunctioning.

[0135] like Figure 47 As shown, the outer casing 31 and the cover 32 are detachably connected by screws, enabling quick assembly and disassembly of the outer casing 31 and the cover 32. This facilitates rapid replacement or repair of the support member 20 and the probe assembly 10 inside the casing 30. At least two screws can be used to ensure a secure connection between the outer casing 31 and the cover 32, preventing the cover 32 from falling off the outer casing 31 due to excessive vibration during the operation of the range hood 1000. In other embodiments, the outer casing 31 and the cover 32 can also be detachably connected using various methods such as snap-fit, pins, or magnetic attraction.

[0136] like Figure 47 As shown, the housing 30 also includes a positioning member 40 disposed in the receiving cavity 311. A first positioning hole 21 is provided on the support member 20, and the positioning member 40 is inserted into the first positioning hole 21. The position of the support member 20 is fixed and restricted within the housing 30, preventing relative movement between the support member 20 and the housing 30, thus ensuring the normal operation of the temperature sensing device 100. Figure 47 As shown, from the first opening 312 of the receiving cavity 311 to the bottom surface of the receiving cavity 311, the cross-sectional area of ​​the positioning member 40 gradually increases, which facilitates the rapid alignment of the positioning member 40 with the first positioning hole 21, and the positioning member 40 can be quickly inserted into the first positioning hole 21. The support member 20 and the housing 30 are integrally molded by injection molding, which enables the rapid processing and manufacturing of the support member 20 and the housing 30.

[0137] like Figure 2 and Figure 47 As shown, there are two positioning elements 40, arranged side by side and spaced apart. These two positioning elements 40 effectively restrict the support element 20, preventing it from rotating relative to the housing 30. Furthermore, they provide good guidance for the support element 20 as it is inserted into the housing 30. In other embodiments, there may be three, four, or more positioning elements 40.

[0138] like Figure 47As shown, the housing 30 has a receiving cavity 311 that matches the outer contour of the support member 20. At least two positioning members 40 are disposed in the receiving cavity 311 and arranged along the first direction. The receiving cavity 311 has a center line arranged parallel to the first direction. The projection of the center line on the horizontal plane and the projection of the first direction on the horizontal plane are arranged alternately, which can play a good role in preventing the support member 20 from being installed into the housing 30, avoiding the support member 20 from being installed backwards, and ensuring the normal use of the temperature sensing device 100.

[0139] like Figure 47 As shown, the first positioning hole 21 is formed on the support member 20, and the support member 20 has a notch 22. The extending direction of the notch 22 is parallel to the axial direction of the first positioning hole 21, and the notch 22 is connected to the first positioning hole 21. The notch 22 allows for a certain degree of deformation of the first positioning hole 21, ensuring that even if the first positioning hole 21 or the positioning member 40 has certain machining errors, the positioning member 40 can still be smoothly inserted into the first positioning hole 21. Furthermore, as... Figure 47 As shown, the outer periphery of the support member 20 extends inward to form a insertion groove 24, which facilitates the user's insertion of their hand and allows the user to apply upward force to the support member 20 to remove it from the housing 30. Furthermore, as... Figure 47 As shown, the support member 20 also has a slot 29, in which the first circuit board 80 is inserted to prevent it from falling off the support member 20. In addition, the user can first integrate the support member 20, the probe mechanism 10 and the first circuit board 80 into a pre-assembled module, and then install the pre-assembled module into the housing 30, which can effectively improve the assembly efficiency of the temperature sensing module 100.

[0140] like Figure 47 As shown, the temperature sensing device 100 also includes a wire pressing structure 50, which is used to press the wire assembly 70 against the support member 20, thereby preventing the wire assembly 70 from jumping and ensuring a better communication connection and detection effect of the temperature sensing device 100. The range hood 1000 can make timely responses and adjustments to ensure the normal operation of the range hood 1000.

[0141] like Figure 47As shown, the pressure structure 50 is movably connected to the positioning member 40. The pressure structure 50 can switch between a first position that blocks the wire assembly 70 and a second position that avoids the wire assembly 70. When the pressure structure 50 is in the first position, it can tightly press the wire assembly 70 against the support member 20; when it is in the second position, it can avoid the wire assembly 70, making it convenient for the user to adjust the position and connection of the wire assembly 70. In other embodiments, the positioning member 40 can also be provided on the support member 20, and the pressure structure 50 can be movably connected to the positioning member 40 on the support member 20, which can also achieve the above effect. Of course, in other embodiments, the pressure structure 50 can also be a foldable or unfoldable folding rod. When the folding rod is in the unfolded state, it can block the wire assembly 70; when it is in the folded state, it can avoid the wire assembly 70.

[0142] Specifically, such as Figure 48 and Figure 47 As shown, the pressure structure 50 is pivotally connected to the positioning element 40. The user can easily switch the pressure structure 50 between a first position and a second position by simply pushing it, facilitating quick switching between different states of the pressure structure 50. Specifically, as... Figure 48 and Figure 47 As shown, the positioning member 40 includes a pivot portion 41 and a positioning post 42 connected sequentially from top to bottom. The positioning post 42 can cooperate with the first positioning hole 21. The wire pressing structure 50 includes a first connecting plate 5101 and a first wire pressing portion 52. The first connecting plate 5101 is pivotally connected to the positioning post 42, and the first wire pressing portion 52 is connected to the first connecting plate 5101. The first wire pressing portion 52 can press the wire assembly 70 against the support member 20. Wherein, as... Figure 48 As shown, the first wire clamping part 52 can be in the shape of a long rod, thereby limiting the position of the wire assembly 70 over a large range. For example, Figure 47 As shown, the diameter of the pivot 41 is smaller than the diameter of the positioning post 42, and a step is formed at the connection position between the pivot 41 and the positioning post 42. The step can achieve a better support effect for the pressure line structure 50.

[0143] like Figure 47 As shown, the outer surface of the support member 20 is recessed downward to form a wire receiving groove 23. At least a portion of the wire assembly 70 is accommodated in the wire receiving groove 23, which can achieve a better pre-positioning effect on the wire assembly 70. The wire pressing structure 50 cooperates with the wire receiving groove 23 to better fix the wire assembly 70 and further prevent the wire assembly 70 from jumping. Figure 48-10As shown, the surface of the wire storage groove 23 is curved, which can prevent damage to the wire assembly 70 and improve the service life of the wire assembly 70.

[0144] like Figure 48-10 As shown, the positioning member 40 has an arc-shaped guide groove 421, and the first connecting plate 5101 is provided with a slider 511. The slider 511 is inserted into the guide groove 421 and can slide along the guide groove 421. When the first connecting plate 5101 rotates relative to the positioning member 40, the slider 511 cooperates with the guide groove 421 to achieve a better guiding effect on the first connecting plate 5101.

[0145] like Figure 4 As shown, the longitudinal section of the guide groove 421 includes a connecting hole 4211 and a connecting groove 4212 connected sequentially from top to bottom. The width of the connecting hole 4211 is smaller than the width of the connecting groove 4212. The slider 511 includes a guide part 5111 and a limiting part 5112. The first connecting plate 5101, the guide part 5111, and the limiting part 5112 are connected sequentially. The guide part 5111 is disposed in the connecting hole 4211, and the limiting part 5112 is disposed in the connecting groove 4212. The connecting hole 4211 can restrict the limiting part 5112 from disengaging from it, preventing the slider 511 from separating from the positioning member 40. Figure 11 As shown, the positioning member 40 is provided with a first placement groove 422. The first placement groove 422 is located at at least one end of the guide groove 421 and is connected to the guide groove 421. The cross-sectional area of ​​the first placement groove 422 is larger than the cross-sectional area of ​​the limiting part 5112, which facilitates the quick assembly and disassembly of the slider 511 and the positioning member 40, and facilitates the replacement of the pressure wire structure 50.

[0146] In other embodiments, such as Figure 12 As shown, this embodiment also provides a wire pressing structure 50, which is basically the same as the aforementioned wire pressing structure 50. The main difference is that the wire pressing structure 50 includes a second connecting part 53 and a second pressing part 54. The second connecting part 53 is connected to the support member 20, and the second pressing part 54 is connected to the end of the second connecting part 53 away from the support member 20. The second pressing part 54, the second connecting part 53, and the support member 20 together form a receiving groove 55. At least a portion of the wire assembly 70 is received in the receiving groove 55. The simple structure of the wire pressing structure 50 can also prevent the wire assembly 70 from jumping, ensuring a better communication connection and detection effect of the temperature sensing detection device 100. The range hood 1000 can make timely responses and adjustments to ensure the normal operation of the range hood 1000.

[0147] The pressure crease structure 50 and the support component 20 are integrally molded by injection molding, which enables rapid processing of the pressure crease structure 50.

[0148] like Figure 13 andFigure 12 As shown, the cover 32 includes a cover body 321 and a cover protrusion 322 disposed thereon. When the cover body 321 covers the first opening 312, the cover protrusion 322 and the bottom plate of the outer shell 31 together clamp the support member 20, which can further realize the stability of the connection between the support member 20 and the shell 30 and prevent the support member 20 from shaking relative to the shell 30.

[0149] like Figure 13 and Figure 14 As shown, the positioning member 40 extends from the bottom surface of the receiving cavity 311 toward the first opening 312. One of the free end of the positioning member 40 and the cover 32 is provided with a positioning protrusion 323, and the other is provided with a positioning groove 411. When the cover 32 covers the first opening 312, the positioning protrusion 323 is engaged in the positioning groove 411, which can further realize the stability of the connection between the support member 20 and the housing 30 and prevent the support member 20 from shaking relative to the housing 30.

[0150] Preferred solutions, such as Figure 14 As shown, the support member 20 is provided with a first limiting part and a second limiting part. The first limiting part is used to limit the probe 11, and the second limiting part is used to limit the second circuit board 12, thereby achieving a stable connection between the probe mechanism 10 and the support member 20. In addition, the limiting reference of at least two probe mechanisms 10 is the same inner support member 20, which facilitates ensuring the phase position accuracy between at least two probe mechanisms 10, thereby ensuring the accuracy of the temperature sensing module 100 detection.

[0151] Specifically, such as Figure 14 As shown, the first limiting part includes a first channel 25 formed on the support member 20 and a clearance hole 26 located beside the first channel 25. The probe 11 is limited within the first channel 25, and the connector weld foot 131 is accommodated in the clearance hole 26. By limiting the probe 11 through the first channel 25, the accuracy of the emission direction of the probe mechanism 10 can be ensured, and the clearance hole 26 can prevent positional interference between the connector weld foot 131 and the support member 20.

[0152] Specifically, in this embodiment, as Figure 14 As shown, the probe mechanism 10 is inserted into the first channel 25 from the rear direction of the support member 20. Preferably, the support member 20 includes a flat portion. After the probe 11 and the connector solder foot 131 are respectively located in the first channel 25 and the clearance hole 26, the second circuit board 12 has one side of the probe 11 abutting against the flat portion of the support member 20. The flat portion can achieve a stable support effect for the probe mechanism 10.

[0153] Preferably, such as Figure 14As shown, the first limiting part also includes a positioning protrusion 27 disposed on the support member 20, and a second positioning hole 121 disposed on the second circuit board 12, with the positioning protrusion 27 inserted into the second positioning hole 121. The cooperation between the positioning protrusion 27 and the second positioning hole 121 not only ensures the accuracy of the angle at which the probe 11 is installed in the first channel 25, but also prevents the probe 11 from rotating within the first channel 25, thereby further improving the accuracy of the probe 11 installation. Specifically, in this embodiment, the first limiting part includes two positioning protrusions 27, and the second circuit board 12 is correspondingly provided with two second positioning holes 121, with each positioning protrusion 27 inserted into one second positioning hole 121. The cooperation between the two sets of second positioning holes 121 and the positioning protrusions 27 further improves the installation accuracy of the probe 11. Preferably, in this embodiment, the line connecting the two positioning protrusions 27 does not pass through the center of the first channel 25, that is, the two positioning protrusions 27 are asymmetrically arranged relative to the first channel 25, thus playing a role in preventing mistaken installation of the probe 11. It is understood that in other embodiments, the first limiting part may also include one, three or more positioning protrusions 27, and the number of second positioning holes 121 on the second circuit board 12 may be the same as the number of positioning protrusions 27.

[0154] Preferably, such as Figures 15-17 As shown, the first limiting part also includes a mounting hole 28 provided on the flat plate. Correspondingly, the second circuit board 12 of the probe 11 is provided with a through hole 122. The temperature sensing module 100 also includes a fastener 14. The fastener 14 passes through the through hole 122 on the second circuit board 12 and connects to the mounting hole 28, thereby locking the position of the probe 11, preventing the probe 11 from shaking during use, and ensuring the accuracy of the probe 11's detection results. Specifically, the mounting hole 28 can be a threaded hole, and correspondingly, the fastener 14 is a bolt. The connection structure is simple and easy to disassemble and assemble. In other embodiments, the fastener 14 can also be a buckle, pin, etc. Specifically, in this embodiment, each first limiting part (i.e., one side of each first channel 25) is provided with two mounting holes 28. Correspondingly, the second circuit board 12 is provided with two through holes 122. That is, the probe 11 is mounted on the inner support by two fasteners 14, which improves the firmness of the probe 11 connection. Furthermore, the two mounting holes 28 are arranged diagonally, thereby further improving the firmness of the probe 11 installation.

[0155] Combination Figures 15-17 The structure of seal 92 is described in detail. For example... Figure 15As shown, the free end of the side wall of the outer casing 31 extends downward to form a wire outlet hole 33. The cover 32 and the side wall of the outer casing 31 together clamp the sealing element 92 in the vertical direction. The sealing element 92, through its contact with the inner wall of the wire outlet hole 33 and the cover 32, provides a sealing and oil-proof function for the interior of the temperature sensing module 100, preventing oil fumes from interfering with the detection of the probe mechanism 10 and preventing the first circuit board 80 from malfunctioning. In addition, the cover 32 can press against the sealing element 92, restricting the relative movement of the external connection line 90 relative to the casing 30 and ensuring a stable connection between the external connection line 90 and the first circuit board 80. Furthermore, the cover 32 and the outer casing 31 are locked together by fasteners such as screws, allowing the cover 32 and the outer casing 31 to tightly clamp the sealing element 92, further improving the sealing effect of the wire outlet hole 33. In addition, users can first insert the seal 92 into the outlet hole 33 from the upper port of the outlet hole 33, and then cover the cover 32 onto the outer shell 31, thereby achieving rapid assembly of the temperature sensing module 100.

[0156] like Figure 17 and Figure 15 As shown, the cover 32 includes a cover body 321 and a first pressing protrusion 325 disposed thereon. At least part of the first pressing protrusion 325 is inserted into the outlet hole 33 and together with the outer shell 31 clamps the sealing member 92 in the vertical direction, thereby achieving a better clamping effect of the cover 32 and the outer shell 31 on the sealing member 92 in the vertical direction.

[0157] like Figure 18 and Figure 15 As shown, the sealing element 92 includes a first abutting portion 921, a first sealing portion 922, and a second sealing portion 923. The first abutting portion 921 is fitted onto the outer periphery of the wire body 91. The first sealing portion 922 and the second sealing portion 923 extend outward from the outer surface of the first abutting portion 921 and are spaced apart in the horizontal direction. The side wall of the outer shell 31 is inserted into the space formed by the first abutting portion 921, the first sealing portion 922, and the second sealing portion 923. The first sealing portion 922 and the second sealing portion 923 clamp the side wall of the outer shell 31 from both the inner and outer sides, further improving the sealing effect of the sealing element 92 on the wire outlet 33. The first sealing portion 922 and the second sealing portion 923 together form a guide insertion groove, and the side peripheral plate 3131 of the shell 30 is inserted into the guide insertion groove, improving the assembly efficiency of the sealing element 92 and the shell 30.

[0158] like Figure 17 and Figure 15 As shown, the first pressing protrusion 325 includes a third sealing part 3251. The third sealing part 3251 and the outer shell 31 together clamp the first abutting part 921 in the vertical direction. The third sealing part 3251 is located inside the first sealing part 922 and abuts against the first sealing part 922 in the horizontal direction, further improving the sealing effect of the sealing member 92 on the outlet hole 33.

[0159] The housing 30 also includes a first annular seal 34. The side wall 313 of the housing 31 includes a side peripheral plate 3131 and an outward protrusion 3133. The outward protrusion 3133 is disposed at the upper end of the side peripheral plate 3131 and surrounds the outer periphery of the side peripheral plate 3131. The first annular seal 34 is held together by the outward protrusion 3133 and the cover 32 in the vertical direction, which can achieve a better sealing effect between the cover 32 and the housing 31, and further prevent oil fumes from entering from the gap between the cover 32 and the housing 31.

[0160] Specifically, such as Figure 16 and Figure 15 As shown, at least one of the bottom surface of the cover 32 and the top surface of the protrusion 3133 is provided with an annular groove 31331. The first annular seal 34 is disposed in the annular groove 31331. The annular groove 31331 can achieve a better limiting effect on the first annular seal 34, improve the assembly efficiency of the first annular seal 34 with the cover 32 or the protrusion 3133, and improve the overall assembly efficiency of the temperature sensing module 100.

[0161] like Figure 17 and Figure 17 As shown, the cover 32 includes a cover body 321 and a flange 324 that surrounds its outer periphery and extends downward. The cover body 321 is located above the protrusion 3133, and the flange 324 surrounds the outer periphery of the protrusion 3133. The flange 324 covers the protrusion 3133, which can achieve the function of draining oil droplets on the cover 32 and prevent oil droplets from entering the housing 30.

[0162] like Figure 19 and Figure 20 As shown, a first step 3241 is provided on the inner wall of the flange 324, and a second step 31332 is provided on the side of the outward protrusion 3133 facing the flange 324. The first step 3241 and the second step 31332 are in concave-convex cooperation, which increases the difficulty of the oil inlet path and prevents oil from entering from the gap between the cover 32 and the outer shell 31. Figure 17 As shown, the cover 32 also includes a hook portion 326 disposed at the free end of the flange 324. When the cover 32 is placed on the outer shell 31, the hook portion 326 hooks with the protruding portion 3133, which can prevent the cover 32 from falling off the outer shell 31 and ensure a stable connection between the cover 32 and the outer shell 31.

[0163] like Figures 21-23 As shown, the cover 32 also includes a second annular seal 35 disposed on the cover body 321. The annular seal 35 is inserted into the first opening 312 and abuts against the inner surface of the side wall 313 of the outer shell 31, increasing the difficulty of the oil inlet route and preventing oil from entering from the gap between the cover 32 and the outer shell 31.

[0164] like Figure 21 As shown, this embodiment also provides another temperature sensing module 100, such as... Figure 21 As shown, the cover 32 extends inward from its outer periphery to form a cable outlet 33. The cover 32 and the side wall of the outer shell 31 together clamp the sealing element 92 in the horizontal direction, which also achieves the effect of sealing the cable outlet 33 with the sealing element 92. In addition, since the sealing element 92 is set on the cover 32, it is convenient for the user to check whether there is a gap between the sealing element 92 and the shell 30.

[0165] like Figure 21 As shown, the sealing element 92 includes a second abutment portion 924, a third sealing portion 925, and a fifth sealing portion 926. The second abutment portion 924 is fitted around the outer periphery of the wire body 91. The third sealing portion 925 and the fifth sealing portion 926 extend outward from the outer surface of the second abutment portion 924 and are spaced apart in the vertical direction. The cover body 32 is inserted into the space formed by the second abutment portion 924, the third sealing portion 925, and the fifth sealing portion 926. The third sealing portion 925 and the fifth sealing portion 926 together clamp the cover body 32 in the vertical direction, further improving the sealing effect of the sealing element 92 on the wire outlet hole 33. The third sealing portion 925 and the fifth sealing portion 926 together form a guide insertion groove, and the cover body 321 is inserted into the guide insertion groove, improving the assembly efficiency of the sealing element 92 and the cover body 321.

[0166] like Figure 23 and Figures 24-31 As shown, the side wall 313 of the outer casing 31 includes a side peripheral plate 3131 and a second pressing protrusion 3132 disposed on its upper end. The second pressing protrusion 3132 and the cover 32 together clamp the second abutting part 924 in the horizontal direction. The third sealing part 925 is disposed above the second pressing protrusion 3132 and abuts against the second pressing protrusion 3132, further improving the sealing effect of the sealing member 92 on the outlet hole 33.

[0167] Example 2

[0168] The kitchen appliance provided in this embodiment can be an integrated stove. The integrated stove in this embodiment includes a motor head and a burner head 2000. The motor head can quickly extract the waste from combustion in the burner head 2000 and the harmful fumes generated during cooking, and discharge them outdoors to reduce pollution and purify the air. The integrated stove also includes a temperature sensing module 100 as in Embodiment 1. The temperature sensing module 100 is installed on the motor head and located above the burner head 2000, enabling precise control of the integrated stove.

[0169] Example 3

[0170] like Figure 25This embodiment provides a range hood 1000 and a temperature sensing module 100. The temperature sensing module 100 in this embodiment is an improvement on the temperature sensing module 100 in Embodiment 1.

[0171] like Figures 26-31 and Figures 26-31 As shown, the filter assembly 60 is detachably connected to the housing 30, enabling quick replacement of the filter assembly 60. When the filter assembly 60 is contaminated with oil or damaged and unable to perform its filtering function, only the filter assembly 60 needs to be replaced, without replacing the entire temperature detection mechanism 100, thus reducing the maintenance and replacement cost of the temperature detection mechanism 100. Furthermore, to achieve compatibility with the corresponding probe 11, only the filter assembly 60 needs to be replaced with one that matches the probe 11, without replacing the entire housing 30, simplifying the replacement process and reducing costs.

[0172] like Figure 27 As shown, the housing 30 includes a first connecting structure 314, and the filter assembly 60 includes a second connecting structure 63. The first connecting structure 314 and the second connecting structure 63 are detachably connected. Through the arrangement of the first connecting structure 314 and the second connecting structure 63, the housing 30 and the filter assembly 60 can be quickly assembled and disassembled. Of course, in other embodiments, the housing 30 and the filter assembly 60 can also be detachably connected via connectors, which also achieves the effect of quick assembly and disassembly. Specifically, the connectors can be screws, pins, etc., facilitating quick assembly and disassembly of the housing 30 and the filter assembly 60 by the operator.

[0173] Specifically, such as Figure 28 As shown, in this embodiment, the first connecting structure 314 is a latching protrusion, and the second connecting structure 63 is a snap-fit. The snap-fit ​​can engage with the latching protrusion. This simple structure enables quick assembly and disassembly of the housing 30 and the filter assembly 60, facilitating operator use. Specifically, the snap-fit ​​in this embodiment is elastically deformable, facilitating quick assembly and disassembly of the snap-fit ​​and the latching protrusion. In other embodiments, the first connecting structure 314 can also be a snap-fit, and the second connecting structure 63 can be a latching protrusion, with the snap-fit ​​engaging with the latching protrusion, achieving the same effect.

[0174] like Figure 27 and Figure 28 As shown, the first connecting structure 314 is a protrusion extending from the light-transmitting opening 36 into the interior of the housing 30, and the second connecting structure 63 is a buckle. The buckle engages with the protrusion inside the housing 30. The protrusion and buckle are hidden inside the housing 30, resulting in a more aesthetically pleasing appearance for the temperature detection mechanism 100. Figure 27 and Figure 28As shown, the filter assembly 60 is inserted into the light-transmitting port 36 and seals the light-transmitting port 36, which can prevent oil and dirt from entering the interior of the housing 30, ensure good detection accuracy of the temperature detection mechanism 100, and prevent damage to the temperature detection mechanism 100. Figure 28 and Figure 26 As shown, the locking protrusion is annular, and the outer peripheral surface of the filter component 60 engages with the inner sidewall of the locking protrusion to make the locking of the filter component 60 and the housing 30 more secure, preventing the filter component 60 from falling off the housing 30. Specifically, the interference fit between the outer peripheral surface of the filter component 60 and the inner sidewall of the locking protrusion further improves the fixing effect between the filter component 60 and the housing 30. Figure 27 As shown, the height of the protrusion in this embodiment is 4mm to 10mm, which allows for a large-area contact between the inner wall of the protrusion and the outer peripheral surface of the filter assembly 60, thereby achieving a better fixing effect between the filter assembly 60 and the housing 30. In other embodiments, multiple protrusions can be provided, arranged at intervals along the circumference of the light-transmitting opening 36. Each protrusion corresponds to a corresponding buckle, and the buckles engage with their respective buckles. This type of housing 31 requires less material.

[0175] An annular sealing ring is fitted onto the outer peripheral surface of the filter assembly 60. The inner sidewall of the latching protrusion and the outer peripheral surface of the filter assembly 60 together clamp the annular sealing ring, thereby preventing external oil contaminants from entering the interior of the temperature detection mechanism 100. The annular sealing ring can be a rubber ring. Specifically, an annular receiving groove can be formed on the inner sidewall of the latching protrusion or on the outer peripheral surface of the filter assembly 60, and the annular sealing ring can be accommodated in the annular receiving groove, which can achieve a better limiting effect on the annular sealing ring.

[0176] like Figure 30 , Figure 29 and Figure 31 As shown, this embodiment has four clips, which are evenly spaced along the circumference of the filter assembly 60. This arrangement ensures good fixation between the filter assembly 60 and the housing 30 at various positions along the circumference of the filter assembly 60, preventing gaps from forming between the filter assembly 60 and the housing 30 in certain areas and preventing external oil from entering the interior of the housing 30. Of course, in other embodiments, the clips can be set to two, three, five, etc.

[0177] Combination Figure 32 , Figure 29 and Figure 31 The structure of the filter assembly 60 will be further described, such as... Figure 32 , Figure 31 and Figure 30As shown, the filter assembly 60 also includes a mounting member 61 and a filter 62. The mounting member 61 is connected to the second connecting structure 63 and has a through hole 6111. The filter 62 is disposed on the mounting member 61 and covers the through hole 6111. The filter 62 can be a silicon wafer. The silicon wafer can filter out stray light other than infrared light, ensuring that the radiation energy entering the probe 11 is only infrared radiation energy, thereby improving the measurement accuracy of the infrared temperature detection mechanism 100.

[0178] like Figure 30 As shown, the mounting component 61 includes a main body 611 and a first adhesive layer 612. The main body 611 has a through hole 6111, and the outer side of the main body 611 is recessed to form a groove 6112, which surrounds the outer periphery of the through hole 6111. The first adhesive layer 612 is disposed in the groove 6112, and the filter 62 is disposed on the outer side of the main body 611 and adhered to the first adhesive layer 612. This ensures a stable connection between the filter 62 and the main body 611, preventing external oil contaminants from entering through the gap between the filter 62 and the main body 611, thus guaranteeing the measurement accuracy of the temperature detection mechanism 100. At least two grooves 6112 are provided, and the at least two grooves 6112 and the through hole 6111 are concentrically arranged. The filter 62 and the main body 611 are fixedly connected at multiple locations by the first adhesive layer 612, thereby improving the fixing effect between the filter 62 and the main body 611. Figure 32 As shown, the outer shape and size of the filter 62 are the same as those of the main body 611, and the overall design of the filter assembly 60 is aesthetically pleasing. Figure 33 As shown, the gap between the filter 62 and the main body 611 can also be sealed by applying glue to further prevent moisture or oil from entering between the filter 62 and the main body 611, ensuring the normal use of the temperature detection mechanism 100.

[0179] Example 4

[0180] like Figure 32 and Figure 32 As shown, this embodiment provides a temperature detection mechanism 100. The structure of the temperature detection mechanism 100 is basically the same as that of the temperature detection mechanism 100 in Embodiment 3. The main difference between the two is that the first connecting structure 314 and the second connecting structure 63 are threaded together. The operator can quickly assemble and disassemble the housing 30 and the filter component 60 by simply turning the screw.

[0181] like Figure 32As shown, the first connecting structure 314 extends from the edge of the light-transmitting opening 36 to the outside or inside of the housing 30 and is annular. The second connecting structure 63 is annular and is fitted with the first connecting structure 314. The first connecting structure 314 and the second connecting structure 63 are threaded together, which can achieve a good fixing effect between the first connecting structure 314 and the second connecting structure 63.

[0182] like Figure 33 As shown, the first connection structure 314 of this embodiment extends to the outside of the housing 30, which makes it easy for the operator to quickly assemble and disassemble the filter component 60 without disassembling the housing 30.

[0183] like Figure 33 and Figure 34 As shown, the second connecting structure 63 is sleeved on the outer periphery of the first connecting structure 314. The free end of the first connecting structure 314 and the mounting member 61 together clamp the filter 62, which can achieve a stable connection between the filter 62 and the mounting member 61, prevent the filter 62 from shifting and causing the light-transmitting opening 36 to be exposed, prevent oil from entering the interior of the housing 31, and ensure the detection accuracy of the temperature detection mechanism 100. In this embodiment, the filter 62 can completely cover the light-transmitting opening 36, and the area of ​​the filter 62 is larger than the area of ​​the light-transmitting opening 36, so as to ensure a good clamping effect of the free end of the first connecting structure 314 and the mounting member 61 on the filter 62.

[0184] like Figure 34 As shown, in this embodiment, the annular second connecting structure 63 is disposed on one side of the plate-shaped mounting member 61. The shape and size of the inner peripheral wall of the second connecting structure 63 are the same as the shape and size of the outer peripheral surface of the filter 62. The filter 62 is assembled in the inner peripheral wall of the second connecting structure 63, and the inner peripheral wall of the second connecting structure 63 is engaged with the outer peripheral surface of the filter 62 to prevent the filter 62 from falling off the second connecting structure 63. The inner peripheral wall of the second connecting structure 63 and the outer peripheral surface of the filter 62 are press-fitted together. Furthermore, a sealing ring can be provided between the inner peripheral wall of the second connecting structure 63 and the outer peripheral surface of the filter 62 to prevent oil from entering through the gap between the filter 62 and the mounting member 61.

[0185] Furthermore, a sealing ring is provided on the inner side of the plate-shaped mounting member 61, surrounding the outer periphery of the through hole 6111. The filter 62 and the plate-shaped mounting member 61 together hold the sealing ring, further preventing oil from entering the interior of the temperature detection mechanism 100. Additionally, an annular mounting groove can be provided on the inner side of the plate-shaped mounting member 61 to hold the sealing ring, preventing it from detaching from the through hole 6111. Specifically, when the sealing ring is placed in the annular mounting groove, it extends 1mm to 2mm beyond the inner side of the mounting member 61, achieving a better sealing effect between the filter 62 and the mounting member 61.

[0186] In other embodiments, the first connecting structure 314 may be a mounting hole opened in the housing 30, and the second connecting structure 63 may be a mounting post, which is inserted into the mounting hole and threaded to the side wall of the mounting hole. Through the above-mentioned first connecting structure 314 and second connecting structure 63, the housing 30 and the filter assembly 60 can also be quickly disassembled and assembled.

[0187] Example 5

[0188] like Figure 14 As shown, this embodiment provides a temperature detection mechanism 100. The structure of the temperature detection mechanism 100 is basically the same as that of the temperature detection mechanism 100 in Embodiment 3. The main difference is that the first connecting structure 314 extends from the edge of the light-transmitting opening 36 to the outside or inside of the housing 30 and is annular. The second connecting structure 63 is annular and fits into the first connecting structure 314. The first connecting structure 314 and the second connecting structure 63 are interlocked by an interference fit, which can also achieve the effect of quick assembly and disassembly of the housing 30 and the filter assembly 60. Figure 35 As shown, in this embodiment, the filter 62 is adhered to the mounting component 61 and completely covers the light-transmitting opening 36.

[0189] In other embodiments, the first connecting structure 314 may be a mounting hole opened in the housing 30, and the second connecting structure 63 may be a mounting post. The mounting post is inserted into the mounting hole and is interlocked with the side wall of the mounting hole. Through the above-mentioned first connecting structure 314 and second connecting structure 63, the housing 30 and the filter assembly 60 can also be quickly disassembled and assembled.

[0190] Example 6

[0191] The temperature sensing module 100 provided in this embodiment is basically the same as the temperature sensing module 100 in Embodiment 1. The main difference between the two lies in the matching method between the first channel 25 and at least two probe mechanisms 10. For example... Figure 35 As shown, in Embodiment 1, the support member 20 has two first channels 25. The probe 11 of each probe mechanism 10 is inserted into the corresponding first channel 25. Each probe 11 is independently housed in its corresponding channel. If there is a processing error in the probe 11 or the first channel 25, the probe 11 will not be able to be installed in the first channel 25, resulting in high processing costs for the temperature sensing module 100. In addition, since the support member 20 has two first channels 25, and the extension directions of the two first channels 25 are set at an angle, the injection mold corresponding to the support member 20 needs to include two core molds with cores pulled in different directions. Therefore, the injection mold structure corresponding to the support member 20 is complex and the mold opening process is complex, resulting in high processing costs for both the support member 20 and the temperature sensing module 100.

[0192] To solve the above problems, such as Figure 36 As shown, in this embodiment, the support member 20 has only one first channel 25. The second circuit board 12 of each probe mechanism 10 is connected to the support member 20. All probes 11 of at least two probe mechanisms 10 are housed in the first channel 25. In this embodiment, the first channel 25 only needs to accommodate at least two probes 11 and allow the light path emitted or received by the probes 11 to pass through. Therefore, the processing accuracy requirements for the first channel 25 and the probes 11 are not high. Even if there are processing errors in the first channel 25 or the probes 11, it will not affect the normal assembly of the temperature sensing module 100, which can effectively reduce the processing cost of the temperature sensing module 100. In addition, since at least two probes 11 in this embodiment are housed in the same first channel 25, the injection mold corresponding to the support member 20 in this embodiment only needs one independent core mold, and the core pulling direction of the core mold is unique. Therefore, the structure of the injection mold corresponding to the support member 20 in this embodiment is simple and the mold opening process is simple, which can effectively reduce the processing cost of the support member 20 and the temperature sensing module 100.

[0193] like Figure 36 As shown, each probe 11 is mounted on its corresponding second circuit board 12. The second circuit board 12 is connected to the support member 20. The relative positions between at least two probes 11 are not fixed. By adjusting the relative positions of each probe 11 and the support member 20, the adaptability of the temperature sensing module 100 to different models of range hoods 1000 can be achieved, thereby improving the versatility of the temperature sensing module 100.

[0194] In other embodiments, at least two probes 11 may share a second circuit board 12, which is connected to the support member 20, thereby enabling rapid assembly of the probe mechanism 10 and the support member 20.

[0195] Since at least two probes 11 in this embodiment are housed in the same first channel 25, probe 11 will affect other probes 11 during operation, affecting the temperature detection accuracy of probe 11. This results in poor detection accuracy of the temperature sensing module 100, making it impossible to achieve precise control of the range hood 100. To solve the above problem, such as Figures 37-43As shown, the probe 11 in this embodiment includes a probe body 111 and a protective cover 112. The probe body 111 is mounted on the mounting component, and the protective cover 112 surrounds the outer periphery of the probe body 111 and extends along the optical path emitted or received by the probe body 111. A second channel 1121 communicating with the probe body 111 is provided on the protective cover 112. The protective cover 112 can protect the probe body 111 inside from the influence of other probe bodies 111, thereby ensuring good temperature detection accuracy for each probe 11 and good temperature detection accuracy for the temperature sensing module 100. Furthermore, the protective cover 112 also prevents the temperature on the support 20 from affecting the probe body 111, enabling accurate temperature detection of the corresponding burner head 2000 by the probe 11. The probe 11 and the inner wall of the first channel 25 are spaced apart in this embodiment, further preventing the temperature on the support 20 from affecting the probe body 111 and enabling accurate temperature detection of the corresponding burner head 2000 by the probe 11.

[0196] like Figure 37 As shown, the protective cover 112 is detachably connected to the probe body 111, enabling quick disassembly and replacement of the protective cover 112. Different lengths of protective covers 112 are matched to different models of temperature sensing modules 100 to improve the versatility of the temperature sensing module 1000. Specifically, the length of the protective cover 112 is between 5mm and 20mm. Specifically, the protective cover 112 and the probe body 111 can be inserted and press-fitted to ensure a stable connection between the protective cover 112 and the probe body 111, preventing the protective cover 112 from falling off the probe body 111 during use. Of course, in other embodiments, to achieve a stable connection between the protective cover 112 and the probe body 111, the protective cover 112 and the probe body 111 can also be connected by means of clips, screws, pins, etc.

[0197] Example 7

[0198] like Figures 37-39 As shown, the temperature sensing module 100 provided in this embodiment is an improvement on the temperature sensing module 100 provided in Embodiment 1, such as... Figure 39As shown, the outer casing 300 has a projection through-hole 3101. The temperature sensing module 100 is located inside the outer casing 300. The light path emitted or received by the temperature sensing module 100 can pass through the projection through-hole 3101, which can prevent the temperature sensing module 100 from directly contacting the external oil fumes, avoid damage to the temperature sensing module 100, ensure the accuracy of the temperature sensing module 100's detection, and achieve the temperature detection of the burner head 2000 by the temperature sensing module 100. Due to the installation error between the temperature sensing module 100 and the outer casing 300, the illumination path of the temperature sensing module 100 may not pass through the projection through-hole, and the temperature sensing module 100 may not be able to achieve accurate temperature detection. In addition, the vibration generated by the range hood 1000 during use will cause the relative position of the temperature sensing module 100 and the outer casing 300 to change, and the illumination path of the temperature sensing module 100 may not pass through the projection through-hole 3101, resulting in the temperature sensing module 100 being unable to achieve accurate temperature detection of the burner head 2000.

[0199] To solve the above problems, such as Figure 39 As shown, the housing 30 includes a boss 37 disposed on the outer shell 31. A first projection channel 371 is formed on the boss 37, and a light-transmitting opening 36 is formed on the outer shell 31. The first projection channel 371 is connected to the light-transmitting opening 36 and corresponds to the illumination path of the probe assembly 10. The boss 37 is inserted from the inside of the decorative panel 310 into the projection through-hole 3101. The illumination path of the probe assembly 10 can be smoothly projected outward through the projection through-hole 3101 via the first projection channel 371, enabling the temperature sensing module 100 to detect the temperature of the burner 2000. Furthermore, even if the range hood 1000 vibrates during use, because the boss 37 is confined within the projection through-hole 3101, the relative position of the temperature sensing module 100 and the outer cover 300 is prevented from changing, ensuring that the illumination path of the probe assembly 10 smoothly passes through the projection through-hole 3101 and is projected outward, achieving accurate detection of the burner 2000 temperature by the temperature sensing module 100. Specifically, as... Figure 40 As shown, the probe assembly 10 includes an electrically connected probe 11 and a second circuit board 12, the second circuit board 12 being electrically connected to a microprocessor. Figure 38 and Figure 38 As shown, the outer shell 31 and the boss 37 are integrally formed. The structure of the shell 30 is simple and can effectively improve the assembly efficiency of the temperature sensing module 100.

[0200] like Figure 39 As shown, the housing 30 is fixedly connected to the decorative panel 310 to further prevent relative displacement between the housing 30 and the decorative panel 310. Specifically, the housing 30 and the decorative panel 310 can be fixed by means of adhesive bonding, fasteners, etc.

[0201] like Figure 40As shown, the outer peripheral surface of the boss 37 and the inner peripheral surface of the projection through hole 3101 are press-fitted together. On the one hand, this can achieve a stable connection between the housing 30 and the decorative panel 310, preventing relative displacement of the temperature sensing module 100 relative to the decorative panel 310. On the other hand, it can prevent external water vapor or oil from entering through the gap between the outer peripheral surface of the boss 37 and the inner peripheral surface of the projection through hole 3101, preventing water vapor or oil from entering the interior of the temperature sensing module 100, and ensuring the normal use of the temperature sensing module 100.

[0202] like Figure 39 and Figure 40 As shown, the filter assembly 60 is disposed at the free end of the boss 37 and covers the first projection channel 371. The filter assembly 60 can be a silicon wafer. The silicon wafer can filter out stray light other than infrared light, ensuring that the radiation energy entering the probe assembly 10 is only infrared radiation energy, thereby improving the measurement accuracy of the temperature sensing module 100. Figure 40 and Figure 40 As shown, the outer surface of the filter assembly 60 is coplanar with the outer surface of the outer cover 300, which can prevent the filter assembly 60 and the outer cover 300 from forming a dead corner for oil accumulation, making it easier to clean the filter assembly 60 and the outer cover 300.

[0203] like Figure 41 As shown, the housing 30 also includes a second adhesive layer 38. The free end of the filter assembly 60 and the boss 37 are bonded together by the second adhesive layer 38, which can prevent the filter assembly 60 from falling off the boss 37. The second adhesive layer 38 can also achieve a good sealing effect on the boss 37 and the filter assembly 60, preventing water vapor or oil from entering the interior of the temperature sensing module 100 and ensuring the accurate detection effect of the temperature sensing module 100. Figures 40-42 and Figure 43 As shown, an annular groove 372 is formed by the inward recess of the free end face of the boss 37. The second adhesive layer 38 is accommodated in the annular groove 372, which enables a stable connection between the filter component 60 and the boss 37 at various circumferential positions, further preventing the filter component 60 from falling off the boss 37. At least two annular grooves 372 are provided, and the at least two annular grooves 372 and the first projection channel 371 are arranged concentrically. The filter component 60 and the boss 37 are fixedly connected at multiple positions by the second adhesive layer 38, thereby improving the fixing effect between the filter component 60 and the main body.

[0204] like Figures 44-48As shown, a receiving groove 373 adapted to the filter component 60 is formed by recessing the free end face of the boss 37. The filter component 60 is housed in the receiving groove 373, which enables the rapid positioning of the filter component 60 and the boss 37 and improves the assembly efficiency of the filter component 60 and the boss 37. In addition, the peripheral wall of the receiving groove 373 can limit the boss 37 and prevent the filter component 60 from falling off the boss 37.

[0205] like Figures 44-46 As shown, the boss 37 includes a support portion 374, which extends from the inner peripheral wall of the first projection channel 371 along its axis. The support portion 374 supports the back of the filter assembly 60, providing stable support for the filter assembly 60. Four support portions 374 are evenly distributed along the circumference of the first projection channel 371, ensuring stable support for each position of the filter assembly 60. In other embodiments, the number of support portions 374 may be two, three, or more.

[0206] Example 8

[0207] like Figure 45 As shown, the temperature sensing module 100 provided in this embodiment is an improvement on the temperature sensing module 100 provided in Embodiment 1. The main difference between the structure of the temperature sensing module 100 in this embodiment and the temperature sensing module 100 in Embodiment 7 lies in the way the housing 30 and the outer cover 300 are fitted together, such as... Figure 48 As shown, the decorative panel 310 has a projection through-hole 3101. The filter assembly 60 is disposed on the outside of the housing 30 and covers the light-transmitting opening 36. The housing 30 is fixed to the inner side of the outer cover 300. The illumination path of the probe assembly 10 can pass through the light-transmitting opening 36, the filter assembly 60, and the projection through-hole 3101 in sequence. The inner sides of the housing 30 and the outer cover 300 together hold the filter assembly 60 to prevent it from falling off the housing 30. This allows the filter assembly 60 to effectively filter the light emitted or received by the probe assembly 10, ensuring good measurement accuracy of the temperature sensing module 100. Specifically, the filter assembly 60 can be an optical glass coated filter, a colored glass filter, a plastic filter, a silicon wafer, quartz glass, etc. The filter assembly 60 with the above structure can achieve good filtering of non-red light.

[0208] like Figure 45 and Figure 47As shown, the outer shell 31 has a recessed inward surface to form a second placement groove 317 adapted to the filter assembly 60. A light-transmitting opening 36 is formed on the bottom surface 3171 of the second placement groove 317. The filter assembly 60 is placed in the second placement groove 317. The second placement groove 317 allows for rapid positioning of the filter assembly 60 and the outer shell 31, improving the assembly efficiency of the outer shell 31 and the filter assembly 60. Furthermore, the side peripheral surface 3172 of the second placement groove 317 can limit the position of the filter assembly 60, preventing it from sliding off the outer shell 31. Specifically, the outer surface of the filter assembly 60 is coplanar with the outer surface of the shell 30, or the outer surface of the filter assembly 60 is 0mm to 5mm lower than the outer surface of the shell 30. Figure 45 and Figure 48 As shown, the outer surface of the filter component 60 is coplanar with the outer surface of the housing 30. When the surface of the housing 30 abuts against the back of the decorative panel 310, the outer surface of the filter component 60 simultaneously abuts against the back of the decorative panel 310, achieving a good clamping effect between the decorative panel 310 and the housing 30 on the filter component 60. Furthermore, because the outer surface of the filter component 60 is coplanar with the outer surface of the housing 30, the temperature sensing module 100 has an aesthetically pleasing appearance. Additionally, no oil accumulation space or dead corner is formed between the filter component 60 and the housing 30, preventing oil accumulation on the exterior of the temperature sensing module 100 and facilitating cleaning of the exterior of the temperature sensing module 100.

[0209] like Figure 45 and Figure 48 As shown, the outer peripheral surface of the filter assembly 60 is in interference fit with the side peripheral surface 3172 of the second placement groove 317, which can achieve a better contact effect between the filter assembly 60 and the side peripheral surface 3172 of the second placement groove 317 in the horizontal direction, and further prevent the filter assembly 60 from separating from the housing 30.

[0210] like Figure 48 and Figure 47 As shown, the cross-sectional area of ​​the light-transmitting opening 36 is smaller than the cross-sectional area of ​​the filter assembly 60. The bottom surface 3171 of the second placement groove 317 supports the filter assembly 60. The solid area of ​​the bottom surface 3171 of the second placement groove 317 without the light-transmitting opening 36 can provide good support for the filter assembly 60. The solid area of ​​the bottom surface 3171 of the second placement groove 317 without the light-transmitting opening 36 can also restrict the filter assembly 60 from entering the interior of the housing 30. Figure 48 As shown, the solid area of ​​the bottom surface 3171 of the second placement slot 317 without the light-transmitting opening 36 includes four support plates connected end to end. The width of each support plate is 3mm to 5mm. The support plates can provide relatively stable support for the filter assembly 60.

[0211] like Figure 46 and Figure 47As shown, the outer contour of the filter component 60 is polygonal, which prevents the filter component 60 from rotating within the second placement groove 317 during use of the temperature sensing module 100. The temperature sensing module 100 also includes a third adhesive layer, through which the filter component 60 and the housing 30 are bonded, making the connection between the filter component 60 and the housing 30 more secure and further preventing the filter component 60 from falling off the housing 30.

[0212] like Figure 46 and Figure 47 As shown, the temperature sensing module 100 also includes a mounting bracket 500, which is fixedly connected to the housing 30 and to the inner side of the outer cover 300, thus achieving a stable connection between the temperature sensing module 100 and the inner side of the outer cover 300. Figure 47 and Figure 48 As shown, the mounting brackets 500 are configured in two sets, and the two sets of mounting brackets 500 are set on both sides of the housing 30, so as to achieve a stable support effect for the housing 30 and avoid the housing 30 from tilting.

[0213] Specifically, such as Figure 47 and Figure 47 As shown, the mounting bracket 500 includes a support frame 510, which includes a connecting plate 5101 and a fixing plate 5102. The connecting plate 5101 is fixedly connected to the housing 30, and the fixing plate 5102 is connected to the connecting plate 5101 and arranged parallel to the inner side of the outer cover 300. The fixing plate 5102 is fixed to the inner side of the outer cover 300 by a fourth adhesive layer. The fixing plate 5102 and the inner side of the outer cover 300 are in surface-to-surface contact with the fourth adhesive layer, so the adhesion between the fixing plate 5102 and the inner side of the outer cover 300 is more stable. In other embodiments, the fixing plate 5102 and the outer cover 300 can also be fixed by using a fixing structure such as clips, screws, bolts, or pins. Figure 47 As shown, the outer casing 31 includes a connecting lug 318, and the mounting bracket 500 also includes a fastener 520. The connecting lug 318 and the connecting plate 5101 are fixedly connected by the fastener 520. Specifically, the fastener 520 can be a clip, screw, bolt, pin, etc., to facilitate quick assembly and disassembly of the connecting lug 318 and the connecting plate 5101. The connecting lug 318 and the body of the outer casing 31 are connected by reinforcing ribs, thereby increasing the connection strength between the connecting lug 318 and the body of the outer casing 31.

[0214] like Figure 47As shown, the fixing plate 5102 is perpendicular to the connecting plate 5101. The support frame 510 also includes a reinforcing plate 5104, which is connected to the fixing plate 5102 and the connecting plate 5101 respectively, to ensure the stability of the support frame 510 structure, prevent the support frame 510 from deforming, realize the stable support of the temperature sensing module 100 by the support frame 510, and improve the detection accuracy of the temperature sensing module 100.

[0215] like Figure 48 As shown, the fixing plate 5102 has an injection hole 51021. Liquid adhesive is injected through the injection hole 51021 between the fixing plate 5102 and the inner surface of the outer cover 300. After the liquid adhesive solidifies, it forms a fourth adhesive layer to fix the fixing plate 5102 and the inner surface of the outer cover 300. The injection hole 51021 enables rapid assembly and fixation of the fixing plate 5102 and the inner surface of the outer cover 300. Multiple injection holes 51021 can be provided to improve the injection efficiency of liquid adhesive. In addition, the multiple injection holes 51021 are evenly distributed on the fixing plate 5102, which enables rapid and uniform diffusion of liquid adhesive.

[0216] like Figure 49 and Figure 50 As shown, the mounting bracket 500 includes at least two positioning protrusions 5103. The at least two positioning protrusions 5103 are disposed on the side of the fixing plate 5102 facing the inner side of the outer cover 300. The at least two positioning protrusions 5103 are at the same height. By setting at least two positioning protrusions 5103, the gap between the fixing plate 5102 and the inner side of the outer cover 300 can be made consistent at all positions, ensuring that the thickness of the fourth adhesive layer formed is consistent at all positions, and the temperature sensing module 100 can achieve accurate temperature detection.

[0217] Example 9

[0218] like Figure 49 and Figure 50 As shown, this embodiment provides a range hood 1000, the structure of which is a further improvement on the range hood 1000 provided in Embodiment 1, such as... Figure 49 and Figure 50 As shown, the shield 400 is located inside the outer cover 300 and on the windward side of the temperature sensing module 100. It can prevent oil fumes or impurities in the oil-gas mixture from the air inlet 3201 from entering the interior of the temperature sensing module 100. The temperature sensing module 100 can maintain good detection sensitivity even under long-term use conditions. The electrical components inside the temperature sensing module 100 can work normally, improving the detection accuracy and service life of the temperature sensing module 100.

[0219] Specifically, such as Figure 50 and Figure 50As shown, the shielding component 400 includes a cover 410, which includes a receiving cavity 4102 with a second opening 41021. The cover 410 is fastened to the inner side of the outer cover 300, and the outer contour of the second opening 41021 abuts against the inner side of the outer cover 300, thereby achieving complete coverage of the cover 410 and the outer cover 300. The cover 410 and the outer cover 300, in combination, can effectively block oil fumes and water vapor, intercepting more than 95% of oil fumes and water vapor. Figures 51-53 As shown, the shielding member 400 also includes a flange plate 420, which extends outward from the outer contour of the second opening 41021. When the shielding member 400 is fastened to the inner side of the outer cover 300, the flange plate 420 and the inner side of the outer cover 300 are fully in contact and fit together, improving the sealing between the shielding member 400 and the decorative panel 310. This effectively prevents oil droplets from entering the interior of the shielding member 400 from the position where the decorative panel 310 and the shielding member 400 meet. Through the setting of the flange plate 420, the shielding member 400 can block more than 97% of oil fumes, water vapor, etc. Specifically, in this embodiment, the flange plate 420 and the cover 410 are integrally formed by processes such as stamping and injection molding, which can effectively improve the processing efficiency of the shielding member 400.

[0220] like Figure 51 As shown, a wiring hole 4101 is provided on the cover 410. The wire assembly 70 can extend from the cover 410 through the wiring hole 4101 to connect with the control mechanism of the range hood 1000. In addition, a sealing structure is provided between the wiring hole 4101 and the wire assembly 70. The sealing structure can prevent oil fumes, water vapor, etc. from the outside of the cover 410 from entering the temperature sensing module 100, further improving the oil and water resistance of the temperature sensing module 100. Specifically, the sealing structure can be a sealing ring, which is sleeved on the outer periphery of the wire assembly 70. The outer periphery of the sealing ring abuts against the inner wall of the wiring hole 4101, and the sealing ring can achieve a good sealing effect for the wiring hole 4101. The wiring hole 4101 is located on the leeward side of the cover 410, which can further reduce the probability of oil fumes, water vapor, etc. coming into contact with the wiring hole 4101, further improving the oil and water resistance of the temperature sensing module 100.

[0221] The flange 420 is bonded to the inner side of the outer cover 300 via an adhesive layer. This ensures a secure connection between the flange 420 and the outer cover 300, preventing the shielding component 400 from falling off the outer cover 300 and providing better protection for the temperature sensing module 100. Furthermore, the adhesive layer further enhances the sealing effect between the shielding component 400 and the outer cover 300, further preventing oil fumes and water vapor from entering the interior of the shielding component 400.

[0222] Example 10

[0223] like Figure 52 As shown, the structure of the range hood 1000 provided in this embodiment is basically the same as that in embodiment nine. The main difference between the two lies in the structure of the shielding member 400: as shown in the figure. Figure 52 and Figure 51 As shown, a large heat dissipation vent 4103 is provided on the basis of the fully enclosed shielding member 400 in Embodiment 9. The heat dissipation vent 4103 is connected to the accommodating cavity 4102. The setting of the heat dissipation vent 4103 can achieve a better heat dissipation effect on the temperature sensing module 100, ensuring the accurate detection of the temperature sensing module 100. Figure 52 As shown, in this embodiment, the heat dissipation vent 4103 is located on the leeward side of the temperature sensing module 100, preventing oil fumes or impurities in the oil-air mixture from the air inlet 3201 from entering the interior of the temperature sensing module 100 through the heat dissipation vent 4103, thereby further improving the accuracy of temperature detection of the temperature sensing module 100. Furthermore, the wire assembly 70 of the temperature sensing module 100 can extend outside the cover 410 through the heat dissipation vent 4103. In addition to its heat dissipation function, the heat dissipation vent 4103 also ensures the extension of the wire assembly 70, thus achieving a dual function.

[0224] like Figure 52 As shown, in this embodiment, both the shielding component 400 and the temperature sensing module 100 are mounted on the mounting bracket 500 to form a pre-installation module. The mounting bracket 500 is fixedly connected to the inner surface of the outer cover 300 by adhesive bonding, fastener fixing, magnetic attraction, etc., thereby achieving a quick and easy connection between the pre-installation module and the outer cover 300. Since the pre-installation module is assembled before being placed into the outer cover 300, it avoids the operator from sequentially positioning the shielding component 400, the temperature sensing module 100, and the mounting bracket 500 inside the outer cover 300, effectively improving the assembly efficiency of the pre-installation module and the outer cover 300. Specifically, as... Figure 51 As shown, the shielding member 400 in this embodiment also includes a connecting side plate 450, which is connected to the cover 410 and the mounting bracket 500, thereby achieving a fixed connection between the shielding member 400 and the mounting bracket 500. Figure 52 As shown, the shielding component 400 in this embodiment also includes a sealing structure 490, which is disposed between the flange plate 420 and the inner surface of the outer cover 300. This reduces the entry of oil fumes and water vapor into the interior of the shielding component 400 and improves the fixation effect between the pre-installed module and the outer cover 300. Specifically, the sealing structure 490 can be made of double-sided adhesive, rubber, or similar materials.

[0225] like Figure 53As shown, the air inlet 3201 of this embodiment is located above the temperature sensing module 100, so the heat dissipation port 4103 of this embodiment is located below the cover 410, thereby preventing oil fumes or impurities in the oil-gas mixture from the air inlet 3201 from entering the interior of the temperature sensing module 100 through the heat dissipation port 4103.

[0226] Combination Figure 52 and Figure 53 The structure of the cover 410 is described below, such as Figure 52 and Figure 52 As shown, the cover 410 includes an end plate 4104, a back plate 4105, and two side plates 4106, wherein, as Figure 52 As shown, the back plate 4105 is disposed on one side of the inner surface of the outer cover 300 and spaced apart from the inner surface of the outer cover 300. Side plates 4106 are disposed on both sides of the back plate 4105 in the width direction, spaced apart and facing each other. An end plate 4104 is disposed at the upper end of the back plate 4105, positioned between the two side plates 4106. The end plate 4104, the back plate 4105, and the two side plates 4106 together form a cavity 4102. The two side plates 4106 and the bottom of the back plate 4105 together form a heat dissipation vent 4103. Figure 52 As shown, the end plate 4104 has a downward sloping tendency from the position where it connects to the inner surface of the outer cover 300 to the position where it connects to the back plate 4105. The end plate 4104 can guide the oil entering from the air inlet 3201 downwards, preventing oil from entering the interior of the temperature sensing module 100 through the gap between the end plate 4104 and the inner surface of the outer cover 300. Figure 52 As shown, the end plate 4104 includes an end plate connecting plate 41041 and an end plate guide plate 41042. The upper ends of the end plate connecting plate 41041, the end plate guide plate 41042 and the back plate 4105 are connected in sequence. The end plate guide plate 41042 has an outwardly convex arc surface, which can ensure that the space of the formed accommodating cavity 4102 is large.

[0227] like Figure 52 As shown, the shielding component 400 also includes an oil-blocking structure 440, which is disposed on the outer surface of the cover 410. The oil-blocking structure 440 can block oil stains to prevent oil from dripping onto the temperature sensing module 100.

[0228] Specifically, the oil-blocking structure 440 includes a diversion section 4401, which is disposed on the outer surface of the cover 410 and located above the heat dissipation vent 4103. The diversion section 4401 is directly opposite the temperature sensing module 100 in the front-to-back direction. The diversion section 4401 can divert oil droplets on the back plate 4105 to both sides to avoid the temperature sensing module 100 and prevent oil droplets from entering the temperature sensing module 100. Specifically, as Figure 52As shown, the width of the outer contour of the flow divider 4401 gradually increases from top to bottom, and the bottom width of the outer contour of the flow divider 4401 is greater than or equal to the width of the temperature sensing module 100. Specifically, as... Figure 53 As shown, the flow divider 4401 includes two guide plates, which are perpendicular to and fixedly connected to the back plate 4105. The ends of the two guide plates are connected, and the distance between the two guide plates gradually increases from top to bottom. This structure of the flow divider 4401 guides oil droplets on the back plate 4105 towards the outside of the temperature sensing module 100. Alternatively, in other embodiments, the flow divider 4401 can be a solid block with a triangular longitudinal section.

[0229] like ​ As shown, the oil-blocking structure 440 of this embodiment also includes a drainage section 4402. The drainage section 4402 is disposed on both sides of the bottom of the diversion section 4401, and is used to guide the oil droplets discharged by the diversion section 4401 to the outside away from the temperature sensing module 100, thereby further preventing the oil droplets from entering the interior of the temperature sensing module 100. Specifically, the drainage section 4402 is a drainage guide plate extending from the bottom of the diversion section 4401 to both sides. The length of the drainage guide plate is 10mm to 20mm, so that the oil droplets can be guided to a position far away from the temperature sensing module 100.

[0230] like ​ As shown, the shielding member 400 in this embodiment also includes a pressing member 480 disposed on the inner side of the back plate 4105. When the shielding member 400 covers the outside of the temperature sensing module 100, the pressing member 480 presses the temperature sensing module 100 against the inner surface of the outer cover 300 in the front-back direction, thereby preventing oil droplets from entering the interior of the temperature sensing module 100 from the front end. Specifically, the pressing member 480 in this embodiment is cross-shaped. The cross-shaped pressing member 480 can also improve the strength and hardness of the shielding member 400, effectively preventing the shielding member 400 from deforming or being damaged.

[0231] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
