[0024] In order to improve the urban air environment, prevent and control air pollution and protect human health, online monitoring and surveillance systems for cooking fumes in the catering industry are widely used.

[0025] At present, the oil fume monitor is often used to directly detect the oil fume gas and determine the oil fume concentration. However, oil fume generally contains a lot of water vapor, which has a great influence on the oil fume concentration value; and in order to prevent water and dust, various detection devices are sealed in the box, which leads to poor heat dissipation conditions and high internal temperature of the oil fume monitor, affecting the detection accuracy of each detection device, and further affecting the accuracy of the detected oil fume concentration.

[0026] In view of this, the present application provides an oil fume detection device, which can remove water vapor in the oil fume gas and improve the accuracy of oil fume concentration detection. At the same time, it can also reduce the temperature inside the box, provide a normal temperature environment for each detection device, ensure the detection accuracy of the detection device, and further improve the detection accuracy of oil fume concentration.

[0027] In one embodiment, Figure 1 As shown, an oil fume detection device is provided, including a box body 10, in which a dual-function module 20, an oil fume detection module 30 and a gas transmission component 40 are arranged, the dual-function module 20 includes a functional part 21 and an isolation chamber 22, the first surface of the functional part 21 and the isolation chamber 22 form a heating space, and the second surface of the functional part 21 is used to reduce the temperature in the box body 10; the functional part 21 is used to heat the gas to be detected in the isolation chamber 22 when the gas transmission component 40 draws the gas to be detected into the isolation chamber 22; the gas transmission component 40 is used to transport the gas to be detected from the isolation chamber 22 to the oil fume detection module 30, so that the oil fume detection module 30 performs oil fume index detection on the gas to be detected.

[0028] in, Figure 1 The left picture is the main view of the interior of the oil fume detection equipment, and the right picture is a partial structural diagram of the left view of the oil fume detection equipment.

[0029] The oil fume detection device provided in the embodiment of the present application includes a housing 10 , a dual-function module 20 , an oil fume detection module 30 and a gas transmission component 40 .

[0030] The dual-function module 20, the oil smoke detection module 30 and the gas transmission component 40 are all arranged in the box body 10, and the box body 10 is used to provide waterproof, dustproof, anti-collision and other protections.

[0031] The dual-function module 20 is used to heat the gas to be detected and remove water vapor in the gas to be detected to avoid the influence of water vapor on the concentration of the gas to be detected; at the same time, it cools down other functional modules and components in the box to avoid excessive temperature affecting the quality of each functional module and component.

[0032] The dual-function module 20 includes a functional component 21 and an isolation chamber 22. When the functional component 21 is working, the first surface is heated and the second surface is cooled. Therefore, the functional component 21 is arranged at the bottom opening of the isolation chamber 22, and the first surface faces the inside of the isolation chamber 22, that is, the first surface of the functional component 21 and the isolation chamber 22 form a heating space; the second surface of the functional component 21 faces the outside of the isolation chamber 22 and is exposed to the inside of the box 10, so as to reduce the temperature inside the box 10.

[0033] The gas delivery assembly 40 is used to Figure 1 In the direction indicated by the middle arrow, the gas to be detected is first drawn into the isolation chamber 22 , then transported from the isolation chamber 22 to the oil fume detection module 30 , and finally discharged out of the box body 10 .

[0034] The functional part 21 is used to form a heating space with the isolation cavity when the gas transmission component 40 draws the gas to be detected into the isolation cavity, heat the gas to be detected, remove water vapor in the gas to be detected, and avoid the influence of water vapor on the concentration of the gas to be detected.

[0035] The isolation cavity 22 is used to isolate the heating space from the remaining space in the box body 10 to prevent the quality of other functional modules and components in the box body 10 from being affected by excessive temperature.

[0036] The oil fume detection module 30 is used to detect the oil fume index of the gas to be detected after the water vapor is removed. The oil fume detection module 30 may be an oil fume sensor; the gas to be detected may be oil fume gas, and the oil fume index may be an oil fume concentration index.

[0037] The embodiment of the present application provides an oil fume detection device, including a box, in which a dual-function module, an oil fume detection module and a gas transmission component are arranged, the dual-function module includes a functional part and an isolation cavity, the first surface of the functional part and the isolation cavity form a heating space, and the second surface of the functional part is used to reduce the temperature in the box to prevent the excessive temperature from affecting the quality of other functional modules and components in the box 10; the functional part is used to heat the gas to be detected in the isolation cavity when the gas transmission component draws the gas to be detected into the isolation cavity, remove the water vapor in the gas to be detected, and avoid the influence of the water vapor on the concentration of the gas to be detected; the gas transmission component is used to transport the gas to be detected from the isolation cavity to the oil fume detection module, so that the oil fume detection module performs oil fume index detection on the gas to be detected. The oil fume detection device provided by the embodiment of the present application can remove the water vapor in the gas to be detected and improve the detection accuracy of the oil fume index of the gas to be detected, while also reducing the temperature in the box, so as to achieve the purpose of reducing the temperature of other functional modules and components in the box, avoiding the excessive temperature of the functional modules, components, etc. affecting the index detection quality, and further improving the detection accuracy of the oil fume index.

[0038] In one embodiment, Figure 2 As shown, the dual-function module 20 further includes a power supply module 23 , which is electrically connected to the functional component 21 and is used to supply power to the functional component 21 so that the functional component 21 generates heat through the first surface and cools through the second surface.

[0039] In the embodiment of the present application, the functional component 21 can enter the working mode by being powered on. Therefore, the dual-function module 20 can also include a power supply module 23, which is electrically connected to the functional component 21 and is used to supply power to the functional component 21.

[0040] After the functional component 21 is powered on, the first surface starts to heat, and the temperature in the isolation cavity 22 starts to rise, thereby forming a heating space; the second surface starts to cool, and the temperature in the box 10 starts to drop, thereby achieving the effect of lowering the temperature of other functional modules and components in the box.

[0041] In a possible implementation, the functional component 21 may be a semiconductor device whose heating temperature and cooling temperature satisfy a preset difference.

[0042] The preset difference may be 40° C., and the semiconductor device may be a semiconductor refrigerator.

[0043] After the power supply module 23 supplies power to the semiconductor device, the first surface of the semiconductor device starts to heat up. When the heating temperature reaches the temperature range of 60-70°C, water vapor can be effectively removed while preventing the heating and cooling effects of the functional component 21 from being affected by excessively high temperature.

[0044] Under this preset difference, the refrigeration temperature is within the range of 20-30°C, which can achieve the effect of lowering the temperature of other functional modules and components in the box 10, providing a normal temperature environment for other functional modules and components sealed in the box 10, and avoiding excessively high temperature affecting the quality of their index detection.

[0045] The oil fume detection device provided in the embodiment of the present application also includes a power supply module, which is electrically connected to the functional part and is used to supply power to the functional part, so that the functional part 21 enters the working mode, and then heats the gas to be detected to remove water vapor through the first surface and cools through the second surface, while achieving the effect of lowering the temperature in the box. In the embodiment of the present application, the functional part is a semiconductor device whose heating temperature and cooling temperature meet the preset difference, so that when the heating temperature of the functional part reaches the temperature range that effectively removes water vapor, the cooling temperature can also provide a normal temperature environment for other functional modules, components, etc. in the box, thereby ensuring the accuracy of oil fume index detection of the gas to be detected from two aspects.

[0046] In one embodiment, Figure 3 As shown, the oil smoke detection device further includes a heating module 50 , which is disposed in the isolation chamber 22 . The heating module 50 is used to transfer heat from the first surface of the functional component 21 , or to dissipate heat under the excitation of the functional component 21 .

[0047] In the embodiment of the present application, the oil smoke detection device further includes a heating module 50 disposed in the isolation chamber 22 .

[0048] In a possible implementation, the heating module 50 is used to transfer the heat of the first surface of the functional component 21. In this case, the heating module 50 can be made of metal such as aluminum and copper, and a channel for the gas to be detected to pass through can be provided inside. When the first surface of the functional component 21 is heated, the heating module 50 can quickly and effectively conduct the heat of the first surface and quickly reach a higher temperature to remove the water vapor of the gas to be detected passing through.

[0049] In a possible implementation, the heating module 50 is used to dissipate heat under the stimulation of the functional part 21. In this case, the heating module 50 may be made of a material that produces a certain chemical reaction under temperature stimulation to dissipate heat. Similarly, a channel for the gas to be detected to pass through is provided inside the heating module 50. When the first surface of the functional part 21 is heated, the heating module 50 dissipates heat under the temperature stimulation of the first surface to heat the gas to be detected, thereby achieving the effect of removing water vapor in the gas to be detected.

[0050] In a possible implementation, the heating module 50 is disposed on the first surface of the functional component 21. The bottom of the heating module 50 can fit the shape of the first surface of the functional component 21, so as to be in full contact with the first surface of the functional component 21, which can improve the efficiency of heat transfer to the first surface of the functional component 21, or improve the heat dissipation efficiency under the heat excitation of the first surface of the functional component 21, thereby improving the efficiency of removing water vapor in the gas to be detected.

[0051] The oil fume detection device provided in the embodiment of the present application also includes a heating module, which is arranged in the isolation cavity and is used to transfer the heat of the first surface of the functional part, or to dissipate heat under the excitation of the functional part 21, so as to heat the gas to be detected passing through the functional module, remove the water vapor in the gas to be detected, and improve the accuracy of the oil fume index detection of the gas to be detected. Furthermore, the functional module is arranged on the first surface of the functional part, fully contacts with the first surface of the functional part, effectively transfers heat, or is excited to dissipate heat, so as to achieve the effect of effectively removing the water vapor in the gas to be detected.

[0052] In one embodiment, Figure 4 As shown, the gas transmission component 40 includes a gas transmission pipeline 41 and a driving device 42 . The gas transmission pipeline 41 passes through the isolation chamber 22 . The driving device 42 is used to transmit the gas to be detected through the gas transmission pipeline 41 .

[0053] In the embodiment of the present application, the gas transmission assembly 40 includes a gas transmission pipeline 41 and a driving device 42. The gas transmission pipeline 41 can be arranged in the box 10 according to Figure 1 The driving device 42 may be a diaphragm pump.

[0054] During the oil fume gas detection process, the driving device 42 draws the gas to be detected into the dual-function module 20 in turn through the gas transmission pipeline 41, so that the dual-function module 20 heats the gas to be detected and removes water vapor in the gas to be detected; then, the gas to be detected after the water vapor is removed is transported to the oil fume detection module 30, so that the oil fume detection module 30 can realize accurate detection of oil fume indicators based on the gas to be detected after the water vapor is removed; finally, the gas to be detected passing through the oil fume detection module 30 is output to the outside of the box 10 of the oil fume detection equipment.

[0055] In the present application embodiment, Figure 5 As shown, the gas transmission pipeline 41 can directly pass through the isolation chamber 22, and the heating space formed in the isolation chamber 22 can heat the gas to be detected in the gas transmission pipeline 41 passing therethrough to remove water vapor in the gas to be detected.

[0056] In a possible implementation, the gas transmission pipeline 41 passing through the isolation cavity 22 can be arranged close to the first surface of the heating element 21 to fully heat the gas to be detected in the gas transmission pipeline 41 and effectively remove the water vapor therein.

[0057] In the oil fume detection equipment provided in the embodiment of the present application, the gas transmission component includes a gas transmission pipeline and a driving device. The driving device is used to transmit the gas to be detected through the gas transmission pipeline. The gas transmission pipeline passes through the isolation cavity. The gas to be detected in the gas transmission pipeline is heated by a heating space formed in the isolation cavity to remove water vapor in the gas to be detected, thereby avoiding the influence of water vapor on the concentration of the gas to be detected and improving the detection accuracy of the oil fume index of the gas to be detected.

[0058] In one embodiment, Figure 6 As shown, the gas transmission component 40 includes a gas transmission pipeline 41 and a driving device 42, and the driving device 42 is used to transmit the gas to be detected through the gas transmission pipeline 41. The isolation chamber 22 is provided with a first through hole 221 and a second through hole 222, and the first through hole 221 and the second through hole 222 are connected to the gas transmission pipeline 41.

[0059] In the embodiment of the present application, a first through hole 221 and a second through hole 222 are provided on the isolation chamber 22, which are respectively connected to the gas transmission pipe 41, so that the driving device 42 can transport the gas to be detected into the isolation chamber 22 through the gas transmission pipe 41 connected to the first through hole 221, and heat the gas to be detected through the heating space formed in the isolation chamber 22 to remove water vapor in the gas to be detected; then, the driving device 42 transports the gas to be detected after the water vapor is removed from the isolation chamber 22 to the oil fume detection module 30 through the gas transmission pipe 41 connected to the second through hole 222, so that the oil fume detection module 30 can accurately detect the oil fume index of the gas to be detected after the water vapor is removed.

[0060] In a possible implementation, when a heating module 50 is provided in the isolation chamber 22, as shown in FIG. Figure 7 As shown, a channel may be provided inside the heating module 50, and the inlet and outlet of the channel are respectively opposite to the first through hole and the second through hole. Figure 7 This is a top view.

[0061] Among them, the shape of the channel can be S-shaped to increase the length of the channel, that is, to increase the time that the gas to be detected passes through the heating module, so that the gas to be detected can be fully heated, thereby achieving the effect of fully removing water vapor in the gas to be detected, and further improving the detection accuracy of the oil fume index of the gas to be detected.

[0062] When the driving device 42 is driven, the gas to be detected is transported into the channel of the heating module 50 through the first through hole 221 and the entrance of the internal channel of the heating module 50, so that the heating module 50 heats the gas to be detected and removes water vapor in the gas to be detected; then, the driving device 42 transports the gas to be detected after the water vapor is removed from the isolation chamber 22 to the oil fume detection module 30 through the outlet of the internal channel of the heating module 50 and the second through hole 222, so that the oil fume detection module 30 can accurately detect the oil fume index of the gas to be detected after the water vapor is removed.

[0063] In the oil fume detection device provided in the embodiment of the present application, a first through hole and a second through hole are provided on the isolation chamber, and the first through hole and the second through hole are connected to the gas transmission pipeline. In the embodiment of the present application, the oil fume detection device can heat the gas to be detected transported into the isolation chamber through the heating space formed in the isolation chamber to remove water vapor in the gas to be detected; a heating module is also provided in the isolation chamber, and a channel is provided in the heating module, and the gas to be detected is heated by the heating module to remove water vapor in the gas to be detected. Compared with heating the gas to be detected by the heating space, heating by a heating module with higher thermal conductivity is more efficient and has a better effect of removing water vapor. Furthermore, the accuracy of oil fume index detection is higher.

[0064] In one embodiment, Figure 8 As shown, the gas transmission component 40 includes a gas transmission pipeline 41 and a driving device 42, the driving device 42 is used to transmit the gas to be detected through the gas transmission pipeline 41, and a plurality of through holes are provided on the heating module 50, and the plurality of through holes are connected to form a channel through a sealing component 60, and the inlet and outlet of the channel are connected to the gas transmission pipeline 41.

[0065] In the embodiment of the present application, a plurality of through holes penetrating the heating module 50 are arranged inside the heating module 50, and the plurality of through holes are connected to form a channel through a sealing assembly 60, the entrance of the channel is opposite to the position of the first through hole 221 of the isolation chamber 22, and is connected to the gas transmission pipeline 41 through the first through hole 221; the exit of the channel is opposite to the position of the second through hole 222 of the isolation chamber 22, and is connected to the gas transmission pipeline 41 through the first through hole 221.

[0066] In one possible implementation, Fig. 9 As shown, the sealing assembly 60 includes a sealing head 61 and a three-way valve 62. The multiple through holes of the heating module 50 are connected to the three-way valve 62 through the sealing head 61, and part of the three-way valve 62 is connected so that the multiple through holes of the multiple heating modules 50 are connected as a channel, and the remaining part of the three-way valve 62 is connected to the gas transmission pipeline 41 as the inlet and outlet of the channel respectively.

[0067] When the driving device 42 is driven, the gas to be detected is transported into the channel of the heating module 50 through the entrance of the channel connected to the inside of the heating module 50, so that the heating module 50 heats the gas to be detected and removes water vapor in the gas to be detected; then, the driving device 42 transports the gas to be detected after the water vapor is removed from the isolation chamber 22 to the oil fume detection module 30 through the outlet of the channel connected to the inside of the heating module 50, so that the oil fume detection module 30 can accurately detect the oil fume index of the gas to be detected after the water vapor is removed.

[0068] In the oil fume detection device provided in the embodiment of the present application, a plurality of through holes are provided on the heating module, and the plurality of through holes are connected to form a channel through a sealing component, and the inlet and outlet of the channel are connected to the gas transmission pipeline. The plurality of through holes provided in the heating module can increase the channel length, that is, increase the time for the gas to be detected to pass through the heating module, so that the gas to be detected can be fully heated, and the effect of fully removing the water vapor in the gas to be detected can be achieved, and the detection accuracy of the oil fume index of the gas to be detected can be further improved.

[0069] In one embodiment, Fig.10 As shown, the oil smoke detection device further includes a cooling module 70 . The cooling module 70 is disposed on the second surface of the functional component 21 . The cooling module 70 is used to transfer the heat of the second surface of the functional component 21 .

[0070] In the embodiment of the present application, the refrigeration module 70 is used to transfer the heat of the second surface of the functional part 21. At this time, the refrigeration module 70 can be made of metal such as aluminum and copper. When the second surface of the functional part 21 is cooled, the refrigeration module 70 can quickly and effectively transfer the temperature of the second surface to quickly reduce the temperature inside the box 10.

[0071] In a possible implementation, the cooling module 70 is used to absorb heat under the stimulation of the functional part 21. At this time, the cooling module 70 can be a material that produces a certain chemical reaction under temperature stimulation to absorb heat. When the second surface of the functional part 21 is cooled, the cooling module 70 absorbs heat under the temperature stimulation of the second surface to reduce the temperature inside the box 10.

[0072] In one possible implementation, the upper surface of the refrigeration module 70 matches the shape of the second surface of the functional component 21 so that the refrigeration module 70 is in full contact with the second surface of the functional component 21, which can improve the heat transfer efficiency to the second surface of the functional component 21, or improve the heat absorption efficiency under heat excitation on the second surface of the functional component 21, thereby effectively reducing the temperature inside the box 10.

[0073] In a possible implementation, the length of the cooling module 70 is greater than the length of the functional part 21, and similarly, the length of the heating module 50 may also be greater than the length of the functional part, so as to further seal the connection between the functional part 21 and the isolation chamber 22, that is, to improve the isolation effect between the heating space and the space inside the box 10, to avoid the mutual influence of the temperatures of the two spaces so that the temperature inside the box 10 is too high, or the temperature inside the isolation chamber 22 cannot reach the temperature to remove water vapor, and further improve the detection accuracy of the oil smoke index of the gas to be detected. Insulation cotton can also be set on the inner wall of the isolation chamber 22 to further improve the isolation effect between the isolation chamber 22 and the box 10.

[0074] The oil fume detection device provided in the embodiment of the present application also includes a refrigeration module, which is arranged on the second surface of the functional part. The refrigeration module is used to transfer the heat of the second surface of the functional part, so as to achieve the effect of lowering the temperature inside the box, provide a normal temperature environment for other functional modules and components in the box, and ensure the accuracy of oil fume index detection of the gas to be detected.

[0075] In one embodiment, Fig.11 As shown, when the oil fume detection device includes a heating module 50, the oil fume detection device may further include a heat dissipation module 80. The heat dissipation module 80 may be a heat dissipation fan, which is arranged at the top opening of the isolation chamber 22 and is used to cool the space in the isolation chamber 22 to prevent the temperature in the isolation chamber 22 from being too high and affecting the heating efficiency of the functional part 21.

[0076] In one embodiment, Fig.12 As shown, the oil fume detection device may also include a controller 91 and a temperature sensor 92.
