Description

Technical Field

[0001] This utility model relates to electrical technology, and in particular to a panel device and a fume extraction device. Background Technology

[0002] As people's demands for quality of life increase, kitchen fume extraction equipment is widely used in households to keep kitchen air clean and improve the user's cooking experience.

[0003] To improve the intelligence of kitchen fume extraction equipment, existing technology provides a type of equipment that includes a main body and a PM2.5 sensor installed within it. The PM2.5 sensor has a detection inlet and a detection outlet on one side, and an air inlet and an air outlet on the upper front side of the main body. The PM2.5 sensor is installed inside the main body, with the air inlet connected to the detection inlet and the air outlet connected to the detection outlet. This allows outside air to enter the PM2.5 sensor through the air inlet and detection inlet for detection, and the detected air flows out through the detection outlet and air outlet. The controller of the fume extraction equipment determines the kitchen air quality based on the detected PM2.5 values ​​and then controls the extraction fan speed accordingly.

[0004] In existing fume extraction equipment, the PM2.5 sensor is usually installed on the front, top, or left and right sides of the top of the unit, and the air inlet and outlet are located on the same side of the unit. This results in the PM2.5 being far from the smoke inlet, making it difficult to quickly detect the occurrence of fume escape. Consequently, the airflow adjustment of the fume extraction equipment lags significantly behind the occurrence of fume escape, reducing the user experience of the fume extraction equipment.

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, 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 this application.

[0045] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0046] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] like Figures 1 to 6 As shown, this embodiment provides an oil fume extraction device, which includes a smoke collection hood 6 with a smoke inlet and a panel device movably installed on the smoke collection hood 6. The panel device can movably open or close the smoke inlet.

[0048] Specifically, the panel device includes a panel 2, a mounting assembly, a control module 4, and an air detection module 1. The panel 2 has a mounting hole, the mounting assembly is disposed on the back side of the panel 2 and surrounds the panel 2 to form a mounting cavity, the control module 4 and the air detection module 1 are arranged side by side in the mounting cavity along a first direction and are limited to the opposite sides of the mounting cavity along the first direction, the air inlet 1222 of the air detection module 1 communicates with the front space of the panel 2 through the mounting hole, and the air outlet 1235 of the air detection module 1 communicates with the external environment of the mounting assembly, the first direction is parallel to the panel 2.

[0049] The panel device provided by this utility model has an air inlet 1222 of the air detection module 1 located on the front side of the panel 2, making the air inlet 1222 close to the oil fume escape port, thereby enabling rapid detection of upward-escaping oil fumes and improving the sensitivity of oil fume escape detection. Since the control module 4 and the air detection module 1 are arranged side-by-side in the mounting cavity and confined between opposite sides of the mounting cavity, it facilitates the installation and positioning of the control module 4 and the air detection module 1 within the mounting cavity. This eliminates the need for other fixing structures to fix the control module 4 and the air detection module 1 in the first direction, improving the ease of assembly and disassembly of the control module 4 and the air detection module 1, and thus improving the ease of assembly and disassembly of the panel device. Because the control module 4 and the air detection module 1 are installed in the mounting cavity, the effect of oil fumes on the air detection module 1 is reduced, improving the user experience of the air detection module 1. Simultaneously, the rear cover 5 shields the air detection module 1, protecting it and reducing the probability of damage.

[0050] The fume extraction device provided by this utility model, by adopting the above-mentioned panel device, can improve the sensitivity of the fume extraction device to wind power control, improve the fume extraction performance of the fume extraction device, and thus improve the user experience of the fume extraction device.

[0051] The fume extraction equipment also includes a controller and a drive mechanism. The drive mechanism rotates panel 2 to open or close the fume inlet. Both the drive mechanism and the air detection module 1 are communicatively connected to the controller. The controller can control the operation of the drive mechanism based on the detection results from the air detection module 1, thereby controlling the opening angle and / or rotation speed of panel 2. Because panel 2 can rotate, when panel 2 is open, the air inlet 1222 is positioned closer to the user cooking, allowing the air detection module 1 to better detect the air quality near the user, thus improving the user experience of the fume extraction equipment.

[0052] This setup allows the air quality detection module 1 to monitor during cooking, and also controls the opening speed and frequency of the control panel 2. Specifically, when the reading from the air detection module 1 suddenly increases, it indicates that some cooking fumes are escaping upwards to the front of the panel 2, meaning that the opening angle of the panel 2 is not sufficient and should be increased. If the panel 2 is currently in the process of opening, it indicates that the opening speed of the panel 2 is relatively slow compared to the rate of fumes generation, and the opening speed of the panel 2 should be increased to meet the needs of fume extraction more quickly and ensure the fume extraction effect of the fume extraction equipment.

[0053] It is worth noting that the specific structure of the controller and drive mechanism can be set with reference to existing technology, which is not the focus of this utility model and will not be elaborated here.

[0054] like Figures 2 to 6 As shown, the air detection module 1 also includes a connecting wire 13. One end of the connecting wire 13 is connected to the air detection module 11, and the other end extends out of the mounting shell 12 and is connected to the control board inside the control module 4. The connecting wire 13 is located inside the mounting cavity, thereby improving the convenience of wiring the air detection module 1.

[0055] It is worth noting that the control module 4 can be either a button module or a touch screen module. This utility model does not limit the specific structure of the touch module or the way it implements control. The specific structure of the control module 4 and the control principle for the fume extraction equipment can be set with reference to the existing technology. This is not the focus of this utility model and will not be elaborated here.

[0056] To improve the ease of installation of the air detection module 1 and the control module 4, the mounting assembly includes a mounting plate 3 and a rear cover 5. The mounting plate 3 is located on the back side of the panel 2 and partially protrudes in a direction away from the panel 2 to form a mounting boss 32. The mounting boss 32 has a mounting opening through which the control module 4 and the air detection module 1 are installed in the mounting cavity. The rear cover 5 is detachably installed at the mounting opening. This design facilitates the installation and removal of the air detection module 1 and the control module 4 within the mounting cavity by removing the rear cover 5, effectively improving the ease of installation and removal of the panel device. Specifically, the mounting plate 3 includes a main body plate portion 31 that fits against the back side of the panel 2, and the mounting boss 32 protrudes rearward relative to the main body plate portion 31.

[0057] To further improve the ease of installation of the air detection module 1 and the control module 4, in this embodiment, both the front and rear sides of the control module 4 and the air detection module 1 abut against the front and rear side walls of the mounting cavity. This effectively limits the control module 4 and the air detection module 1 in the front-rear direction, eliminating the need for additional structures to achieve this limitation and simplifying the panel device's structure. In other embodiments, other structures can be provided within the mounting cavity to limit the control module 4 and the air detection module 1 in the front-rear direction.

[0058] Specifically, the front sides of the air detection module 1 and the control module 4 are both attached to the panel 2, and the rear sides of the air detection module 1 and the control module 4 are both attached to the back cover 5.

[0059] In this embodiment, the first direction is the height direction of the panel 2, which reduces the size of the mounting components in the left-right direction and improves structural compactness. Furthermore, the air detection module 1 is positioned below the control module 4, facilitating its lower placement and improving the flexibility of the air outlet 1235. Specifically, the lower side of the air detection module 1 abuts against the mounting boss 32, and its upper side abuts against the upper side of the control module 4; the upper side of the control module 4 abuts against the mounting boss 32.

[0060] In other embodiments, the first direction is the height direction of the panel 2, and the air detection module 1 is disposed above the control module 4. In yet another embodiment, the first direction can be the left-right direction of the panel 2.

[0061] Furthermore, the mounting boss 32 includes a boss base plate portion 321 that is opposite to and spaced apart from the panel 2 and a boss side portion 322 that connects the boss base plate portion 321 and the main body plate portion 31. The boss base plate portion 321 is provided with a mounting opening.

[0062] The mounting boss 32 has a first positioning groove 3241 that communicates with the mounting cavity. The side of the air detection module 1 away from the control module 4 is inserted into the first positioning groove 3241, which facilitates the installation and positioning of the air detection module 1 on the mounting boss 32. At the same time, this arrangement can also position and limit the installation position of the air detection module 1 relative to the mounting boss 32 in the second direction, ensuring the installation efficiency and reliability of the air detection module 1. The second direction is perpendicular to the first direction and parallel to the panel 2.

[0063] The mounting boss 32 is provided with a second positioning groove 3251 communicating with the mounting cavity. A positioning protrusion 41 is provided on the side of the control module 4 away from the air detection module 1. The positioning protrusion 41 is inserted into the second positioning groove 3251, thereby achieving the installation and positioning of the control module 4 on the mounting boss 32, improving assembly efficiency and reducing assembly difficulty. Simultaneously, the cooperation between the positioning protrusion 41 and the second positioning groove 3251 enables the control module 4 to be installed and positioned in the second direction, improving the ease of disassembly and assembly and the installation accuracy of the control module 4. Furthermore, the positioning protrusion 41 protrudes relative to the main structure of the control module 4.

[0064] To improve the ease of installation of the air detection module 1, the mounting opening has a first side and a second side disposed opposite to each other in a first direction; the first side is connected to a first side plate portion 324, the free end of the first side plate portion 324 extends toward the second side, and the first side plate portion 324 is provided with a first positioning groove 3241; and / or, the second side is connected to a second side plate portion 325, the free end of the second side plate portion 325 extends toward the first side, and the second side plate portion 325 is provided with a second positioning groove 3251.

[0065] That is, both the first side plate portion 324 and the second side plate portion 325 are parallel to the panel 2. By setting the first side plate portion 324 and the second side plate portion 325, it is beneficial to set the first positioning groove 3241 or the second positioning groove 3251, reduce the processing difficulty of the mounting plate 3, and facilitate the assembly accuracy of the air detection module 1 and the control module 4 by controlling the dimensions of the first side plate portion 324 and the second side plate portion 325.

[0066] Specifically, a first positioning groove 3241 is provided on the upper side of the first side plate 324, and the lower side of the air detection module 1 is inserted into the first positioning groove 3241; a second positioning groove 3251 is provided on the lower side of the second side plate 325, and a positioning protrusion 41 is provided on the upper side of the control module 4.

[0067] In other embodiments, a boss structure may be provided protruding from the cavity of the mounting cavity, and a first positioning groove 3241 and a second positioning groove 3251 may be provided on the boss structure.

[0068] To further improve the installation stability of the control module 4, a side limiting part is provided on the mounting boss 32, and one of the opposite sides of the control module 4 in the second direction abuts against the side limiting part. This arrangement limits the installation position of the control module 4 in the second direction, thereby improving the installation stability and reliability of the control module 4.

[0069] In this embodiment, the control module 4 has a positioning protrusion 41 protruding from the middle position in the second direction, and the end of the control module 4 in the second direction abuts against the side limiting part, so that the control module 4 has multiple positions in the second direction that contact and limit the mounting boss 32, thereby effectively improving the limiting reliability of the control module 4 in each direction.

[0070] In this embodiment, a first limiting groove 3242 is formed at one end of the first side plate portion 324 along the second direction towards the second side plate portion 325. The side of the control module 4 closest to the air detection module 1 and its adjacent side abut against the two side walls of the first limiting groove 3242, respectively. A second limiting groove 3252 is formed at one end of the second direction towards the first side plate portion 324. The side of the control module 4 away from the air detection module 1 and its adjacent side abut against the two side walls of the second limiting groove 3252, respectively. By providing the first limiting groove 3242 and the second limiting groove 3252, the position of the control module 4 in the height and left-right directions can be effectively limited, improving the ease of installation of the control module 4. In other embodiments, the first limiting groove 3242 may be provided only on the first side plate portion 324, or the second limiting groove 3252 may be provided only on the second side plate portion 325. In this embodiment, the groove walls of the first limiting groove 3242 and the second limiting groove 3252 form a side limiting part.

[0071] In this embodiment, the edge of the mounting opening is folded towards the panel 2 to form a flange 323, and the rear cover 5 is inserted into the mounting opening and abuts against the flange 323. This arrangement ensures that the distance between the first side plate 324 and the second side plate 325 and the panel 2 is smaller than the distance between the boss base plate 321 and the panel 2. As a result, when the rear cover 5 is installed on the mounting boss 32, the back of the rear cover 5 can be flush with the back of the boss base plate 321, thereby improving the overall flatness and facilitating the cleaning of the fume extraction equipment.

[0072] Furthermore, the flange portion 323 is folded on opposite sides in the first direction to form a first side plate portion 324 and a second side plate portion 325, thereby increasing the difficulty of setting the first side plate portion 324 and the second side plate portion 325, and thus reducing the processing difficulty of the mounting plate 3. Specifically, the flange portion 323 on the lower side is folded upward to form the first side plate portion 324 near the panel 2, and the flange portion 323 on the upper side is folded downward to form the second side plate portion 325 near the panel 2.

[0073] In this embodiment, the rear cover 5 includes a cover plate and a noise reduction structure covering the rear side of the cover plate. The cover plate has multiple noise reduction holes. This structure of the rear cover 5 can not only shield the air detection module 1 and the control module 4, but also reduce the noise transmitted from inside the fume extraction equipment, thereby improving the user experience of the fume extraction equipment.

[0074] To further enhance the user experience of the fume extraction equipment, the panel device also includes a light 7. A light hole is provided on the lower side of the mounting component, and the light 7 is installed in the light hole and connected to the power board within the control module 4. This integrates the light 7 onto the flip device, improving the structural integration of the panel device and enhancing the user experience of the fume extraction equipment.

[0075] To enable the wiring between the control module 4 and the main controller of the fume extraction equipment, a wiring trough 8 is provided on the back side of the mounting plate 3. The wiring trough 8 and the mounting plate 3 form a wiring trough. The wires of the control module 4 pass through the mounting boss 32 and then through the wiring trough. The connection method and specific wiring structure between the control module 4 and the main controller can be set with reference to the existing technology. This is not the focus of this utility model, and this embodiment does not limit or elaborate on it.

[0076] like Figures 5 to 8 As shown, the air detection module 1 includes a mounting housing 12 and an air detection module 1 disposed inside the mounting housing 12. The air detection module 11 has a detection inlet 111 and a detection outlet 112. In this embodiment, the air detection module 11 has a first side facing the panel 2, and both the detection inlet 111 and the detection outlet 112 are disposed on the first side, thereby making the structure of the air detection module 11 more versatile.

[0077] The mounting housing 12 has an air inlet 122 protruding from the side facing the panel 2. The air inlet 122 is inserted into the panel 2 and has an air inlet channel 1221. One end of the air inlet channel 1221 is directly connected to the detection inlet 111, and the other end forms an air inlet 1222. By providing the air inlet 122 and inserting it into the panel 2, it is convenient to achieve the installation and positioning of the air detection module 1 on the panel 2, thereby improving the installation convenience and reliability of the air detection module 1 on the panel 2.

[0078] It is worth noting that the air detection module 11 can be a PM2.5 sensor or other sensors that require air circulation for air quality detection. The air detection module 11 can adopt existing general-purpose modules, that is, the structure of the air detection module 11 can adopt existing structures, and the specific structure and detection principle of the air detection module 11 can be set with reference to existing technology. This is not the focus of the improvement of this utility model, and this utility model does not impose specific limitations in this regard.

[0079] In this embodiment, the air intake 122 is a cylindrical structure perpendicular to the panel 2. The panel 2 has a mounting hole, in which the air intake 122 is inserted. The mounting hole is a circular hole. By setting the air intake 122 in a cylindrical structure, the processing difficulty of the air intake 122 and the mounting hole can be reduced, the cost can be reduced, and the smoothness of airflow in the air intake channel 1221 can be improved. Since the air intake 122 extends along the first side perpendicular to the air detection module 11, the air detection module 1 can meet the installation requirements while the air intake channel 1221 can be as short as possible, thereby shortening the airflow path of the air detection module 11 and better ensuring the detection sensitivity and reliability of the air detection module 1.

[0080] In other embodiments, the air intake 122 may also be a rectangular block structure or a structure of other shapes, as long as the air intake 122 is inserted into the mounting hole.

[0081] In this embodiment, the air outlet 1235 of the air detection module 1 is located on the back side of the panel 2. A vent hole communicating with the mounting cavity is provided on the mounting assembly, and the air outlet of the air detection module 1 communicates with the external environment through the vent hole. Because the air outlet 1235 is located on the back side of the panel 2, it is situated within the negative pressure zone during the operation of the fume extraction equipment. This allows the negative pressure generated by the fan to expel the air inside the air detection module 11 as quickly as possible, reducing the residence time of air inside the air detection module 11 and thus reducing the probability of grease accumulation inside the air detection module 11, thereby ensuring the long-term performance of the air detection module 11.

[0082] In other embodiments, such as Figure 9 As shown, a vent is provided on the panel 2. The air outlet of the air detection module 1 is connected to the external environment through the vent. That is, the air inlet 1222 and the air outlet 1235 of the air detection module 1 are both exposed on the front side of the panel 2 and are connected to the front space of the panel 2.

[0083] In this embodiment, as Figures 6 to 8 As shown, to improve the ease of setting the air outlet 1235, an air outlet 123 protrudes from the side of the mounting housing 12 facing the panel 2. The air outlet 123 extends in a direction parallel to the panel 2, and an air outlet channel 1231 is provided inside the air outlet 123. The first end of the air outlet channel 1231 is connected to the detection outlet 112, and the other end of the air outlet channel 1231 forms the air outlet 1235. By setting the air outlet 123, the orientation of the air outlet 1235 can be controlled through the structure of the air outlet 123, thereby ensuring that while the detection inlet 111 and the detection outlet 112 are located on the same side of the air detection module 11, the air inlet 1222 and the air outlet 1235 have different orientations, thus improving the ease of setting the air detection module 1.

[0084] In other embodiments, the detection inlet 111 and detection outlet 112 of the air detection module 11 may not be located on the same side of the air detection module 11. For example, the detection inlet 111 may be located on the side of the air detection module 11 facing the panel 2, and the detection outlet 112 may be located on the lower side of the air detection module 11. In this case, the air outlet 1235 may be directly connected to the detection outlet 112.

[0085] In this embodiment, the air outlet 123 extends downward, meaning the air outlet channel 1231 extends downward from the first end to the second end. The lower end of the air outlet channel 1231 forms an air outlet 1235. A vent hole is provided on the lower side of the mounting assembly, and the air outlet of the air detection module 1 communicates with the external environment through the vent hole. By providing the downward-extending air outlet 123, the air inlet channel 1221 is positioned downward, which effectively improves the exhaust smoothness of the air outlet channel 1231, thereby further reducing the residence time of airflow inside the air detection module 11, reducing the probability of grease accumulation in the detection channel of the air detection module 11, and improving the detection sensitivity and reliability of the air detection module 11. In other embodiments, the air outlet 123 may also extend in other directions. Specifically, a vent hole is provided on the lower side of the mounting boss 32.

[0086] In this embodiment, the side of the air outlet 123 facing the panel 2 is a plane, which fits into the panel 2. This improves the reliability and stability of the air detection module 1 on the panel 2, and also reduces the probability of grease entering between the air detection module 1 and the panel 2.

[0087] The air detection module 1 also includes an air intake filter 15, which is installed at the air inlet 1222 to filter the airflow entering the detection inlet 111, preventing dust and other impurities from entering the interior of the air detection module 11 and causing blockage of the internal detection channels. The air intake filter 15 can be welded or installed at the air inlet 1222 in a detachable manner. In this embodiment, the air intake filter 15 is flush with the front side of the panel 2 to better ensure the surface flatness of the fume extraction equipment, facilitating cleaning and maintenance of the fume extraction equipment.

[0088] The air detection module 1 also includes an exhaust filter 16, which covers the exhaust port 1235 to prevent external dust or impurities from entering the air detection module 11 through the exhaust port 1235, thus preventing blockage of the exhaust channel 1231 and the detection channel inside the air detection module 11 and improving the long-term performance of the air detection module 11. Specifically, the exhaust part 123 is inserted into the vent hole and the exhaust filter 16 is located at the opening of the vent hole to ensure smooth exhaust while avoiding the problem of the air detection module 1 protruding from the mounting boss 32.

[0089] In other embodiments, when the vent is provided on the panel 2, the air outlet 123 is inserted into the vent, and the air outlet filter 16 is on the front side of the panel 2.

[0090] like Figures 5 to 8 As shown, the mounting housing 12 further includes a mounting cavity in which the air detection module 11 is installed. A separate air inlet communication hole 1211 and an air outlet communication hole 1212 are provided on the cavity wall opposite the air inlet 1222. The air inlet communication hole 1211 communicates directly with both the detection inlet 111 and the air inlet channel 1221. The air outlet communication hole 1212 communicates with the detection outlet 112 and the air outlet channel 1231. The orthographic projection of the air inlet communication hole 1211 on the first side covers the detection inlet 111, and the orthographic projection of the air outlet communication hole 1212 on the first side covers the detection outlet 112.

[0091] Both the intake port 1211 and the exhaust port 1212 are circular holes to accommodate the detection outlet 112 on the air detection module 11. The diameter of the intake port 1211 is smaller than that of the exhaust port 1212 to ensure smooth exhaust.

[0092] To improve the ease of assembly and disassembly of the air detection module 11, the mounting housing 12 includes a main housing and a cover 124 that are interlocked in a first direction. An air inlet 122 and an air outlet 123 protrude from the side of the main housing away from the cover 124. The main housing and the cover 124 together form a mounting cavity. Specifically, the main housing includes a main housing portion 121, which is detachably connected to the cover 124 and forms the mounting cavity. The air inlet 122 and the air outlet 123 protrude from the side of the main housing portion 121 away from the cover 124. Further, a wire through hole is provided on the side wall of the main housing portion 121, through which the connecting wire 13 passes out of the mounting housing 12.

[0093] In this embodiment, the air outlet 1235 is rectangular to facilitate the structural arrangement of the air outlet 123. Furthermore, the cross-sections of the air outlet 123 and the air outlet channel 1231 are rectangular to reduce the machining difficulty of the air outlet 123. In other embodiments, the outer contour of the cross-section of the air outlet 123 may also be trapezoidal or other shapes.

[0094] To improve airflow smoothness, in this embodiment, the end wall of the air outlet channel 1231 away from the air outlet 1235 is an arc-shaped end wall 1232, which is coaxially and has the same diameter as the air outlet connecting hole 1212. By providing an arc-shaped end wall 1232 that is coaxially and has the same diameter as the air outlet connecting hole 1212, it is beneficial to guide the airflow from the air outlet connecting hole 1212 to flow smoothly into the air outlet channel 1231, reduce flow resistance, and thus improve exhaust smoothness.

[0095] The air outlet channel 1231 has two main channel walls 1233 arranged opposite to each other. The two ends of the arc-shaped end wall 1232 are connected to the two main channel walls 1233 through inclined channel walls 1234 respectively. The distance between the two inclined channel walls 1234 gradually increases in the direction towards the air outlet 1235. This arrangement, through the setting of the inclined channel walls 1234, guides the air entering through the air outlet connecting hole 1212 to flow smoothly into the air outlet channel 1231, further improving the smoothness of air outlet.

[0096] The inclined channel wall 1234 is smoothly connected to the main channel wall 1233 and the arc-shaped end wall 1232. Specifically, the inclined channel wall 1234 and the arc-shaped end wall 1232 are tangentially arranged, and the inclined channel wall 1234 and the main channel wall 1233 are connected by an arc transition. The included angle between the inclined channel wall 1234 and the main channel wall 1233 is preferably °~° to avoid the problem that the included angle is too small, resulting in an excessively large gap between the two main channel walls 1233, which would cause the air outlet 123 to be too large.

[0097] In this embodiment, the air detection module 1 further includes a sealing element 14, which is sandwiched between the mounting housing 12 and the air detection module 11 and is at least partially located between the detection inlet 111 and the detection outlet 112. The sealing element 14 can separate the air intake airflow of the detection inlet 111 from the air exhaust airflow of the detection outlet 112, thereby preventing the exhaust airflow from the detection outlet 112 from flowing back to the detection inlet 111 and causing a decrease in detection accuracy. This is more conducive to ensuring the detection reliability of the air detection module 1 and improving the detection sensitivity of the air detection module 1.

[0098] In this embodiment, the seal 14 adopts a gasket structure. The seal 14 has a first arc-shaped edge and a second arc-shaped edge with openings facing away from each other. The first arc-shaped edge surrounds the air inlet communication hole 1211, and the second arc-shaped edge surrounds the air outlet communication hole 1212. The portion located between the first and second arc-shaped edges is situated between the detection inlet 111 and the detection outlet 112, separating the detection inlet 111 and the detection outlet 112. This structure of the seal 14 is easy to assemble and can effectively ensure airflow separation. In other embodiments, the seal 14 includes two sealing rings, one of which surrounds the air inlet communication hole 1211, and the other sealing ring surrounds the air outlet communication hole 1212.

[0099] To improve the ease of installation of the seal 14, a sealing groove is provided at the bottom of the mounting cavity. The shape of the sealing groove is adapted to the shape of the seal 14. The seal 14 is placed in the sealing groove to achieve the installation and positioning of the seal 14.
