[0028] Oil smoke is usually produced during the process of heating food. Oil smoke is a black substance produced by incomplete combustion of oil. It is very sticky and difficult to clean after condensation. It also contains a variety of harmful substances, such as acrolein, benzene, formaldehyde, crotonaldehyde, volatile nitrosamines, etc. Once inhaled, it will cause irreversible damage to the cook's body. Therefore, in the kitchen, a range hood is usually installed for the stove to reduce the amount of oil smoke inhaled by the cook.

[0029] At present, common range hoods usually directly inhale smoke from indoors and exhaust it to the outside, thus preventing smoke from being inhaled by people cooking indoors to a certain extent. However, smoke gradually cools down during the exhaust process, and some oil smoke accumulates in the flue, which is difficult to clean, and is prone to blockage and erosion of the flue, affecting the normal use of the range hood. In addition, the exhaust smoke contains more harmful substances, which will pollute the external environment.

[0030] In order to improve or solve the above technical problems, the inventors of the present application have proposed at least the following embodiments after long-term research.

[0031] See also Figure 1 , Figure 2 , Figure 3 , Figure 1 This is a schematic diagram of the assembly structure of the air intake device provided by the present invention. Figure 2 This is a schematic cross-sectional structural diagram of the air intake device provided by the present invention. Figure 3 This is a schematic cross-sectional view of an embodiment of a device body provided by the present invention. This embodiment of the application provides an air suction device 1 for sucking aerosol containing oil smoke. The air suction device 1 includes a device body 2, a fluid adsorption component 3 and a fluid.

[0032] An inhalation channel 21 and an exhaust channel 22 may be formed in the device body 2. The inhalation channel 21 is used to inhale the first aerosol 7, and the exhaust channel 22 is used to exhaust the second aerosol 8. The fluid adsorption component 3 includes a spraying member 31 and a spraying chamber 32. The inhalation channel 21 can be connected to the exhaust channel 22 through the spraying chamber 32. The spraying member 31 is used to spray fluid into the spraying chamber 32.

[0033] The first aerosol 7 is an aerosol collected from the room by the air suction device 1 and transported to the fluid adsorption component 3 through the inhalation channel 21. The first aerosol 7 contains oil smoke generated in the indoor cooking area. After the first aerosol 7 is processed by the fluid adsorption component 3, many oil smokes are removed by the fluid adsorption component 3, thereby forming a relatively clean second aerosol 8. The second aerosol 8 is an aerosol output from the fluid adsorption component 3 to the discharge channel 22. In terms of oil smoke content, the second aerosol 8 is lower than the first aerosol 7.

[0034] In the structure provided in this embodiment, by setting a fluid adsorption component 3 between the suction channel 21 and the discharge channel 22, the spray part 31 is used to spray fluid to the first aerosol 7 entering the spray chamber 32, and the fluid can be used to adsorb the oil fume in the first aerosol 7, thereby achieving the effect of removing the oil fume, so that the oil fume content of the second aerosol 8 entering the discharge channel 22 through the fluid adsorption component 3 is relatively low, which can improve the oil fume removal effect of the air intake device 1, thereby facilitating the cleaning and maintenance of the discharge channel 22 of the air intake device 1, and can discharge a relatively clean second aerosol 8, thereby reducing the pollution caused by the air intake device 1.

[0035] Optionally, the spraying member 31 sprays the fluid by atomizing the fluid and spraying it into the spraying chamber 32 to contact the first aerosol 7. The spraying member 31 sprays the fluid by spraying a continuous liquid column into the spraying chamber 32 to contact the fluid with the first aerosol 7.

[0036] In a specific embodiment of the present application, the device body 2 may include a power member 4 and a circulation pipeline 5. One end of the circulation pipeline 5 is connected to the bottom of the spray chamber 32, and the other end of the circulation pipeline 5 may be connected to the spray member 31. The power member 4 may be arranged in the circulation pipeline 5 and / or the spray chamber 32. When the power member 4 is working, the fluid at the bottom of the spray chamber 32 can enter the spray member 31 again through the circulation pipeline 5.

[0037] Through the structure provided in this embodiment, one end of the circulation pipeline 5 can be used to collect the fluid that naturally falls after spraying from the bottom of the spray chamber 32. Under the action of the power part 4, the fluid can re-enter the spray part 31 from the other end of the circulation pipeline 5, so that the limited fluid can be used to adsorb the oil smoke in the first aerosol 7 that continuously flows into the spray chamber 32, which can realize the recycling and reuse of the fluid, improve the utilization rate of the fluid, and then improve the availability of the suction device 1.

[0038] Optionally, since the oil fume content in the second aerosol 8 is low and relatively safe for the human body, the exhaust channel 22 can be provided with an opening connected to the indoor room, so as to discharge at least part of the second aerosol 8 back into the indoor room to balance the air pressure difference between indoor and outdoor, alleviate the phenomenon of excessive indoor and outdoor air pressure difference caused by drawing a large amount of indoor aerosol to the outdoors, thereby reducing the probability of adverse situations such as smoke backflow, and improving the availability of the inhalation device 1.

[0039] In a specific embodiment of the present application, the circulation pipeline 5 may further include a purification component 6, which can be used to process the fluid. A collection liquid path 51 and an output liquid path 52 may be formed in the circulation pipeline 5, and the spray chamber 32 is connected to the purification component 6 through the collection liquid path 51, and the purification component 6 is connected to the spray component 31 through the output liquid path 52.

[0040] When the fluid contains oil smoke, its ability to remove oil smoke may decrease, and even due to the spraying process, the oil smoke in the fluid may form small particles again and follow the second aerosol 8 into the discharge channel 22, causing adverse effects on the oil smoke removal effect of the air suction device 1. Through the structure provided in this embodiment, a purification component 6 is provided between the collection liquid path 51 and the output liquid path 52 of the circulation pipeline 5, and the purification component 6 can be used to purify the fluid collected by the collection liquid path 51 from the spray chamber 32, so that the oil smoke in this part of the fluid is removed by the purification component 6, reducing the probability of the oil smoke removal ability being reduced due to excessive oil smoke content in the fluid, so that when the fluid enters the spray component 31 through the output liquid path 52 and is sprayed again, the oil smoke in the first aerosol 7 can continue to be effectively removed.

[0041] Moreover, the fluidity of the fluid will also be affected by the oil smoke therein. When the fluid passes through the spray element 31, the circulation pipeline 5 and other positions, the oil smoke therein may cause blockage and affect the circulation process of the fluid. Adding a purification element 6 to remove the oil smoke in the fluid can also improve the stability of the suction device 1.

[0042] Optionally, since the oil fume content in the fluid entering the purification element 6 through the collecting liquid path 51 is relatively high, the radial dimension of the collecting liquid path 51 can be larger than the radial dimension in the output liquid path 52 and the spray element 31, thereby facilitating the passage of the fluid containing oil fume, reducing the probability of the circulation pipeline 5 being blocked by the oil fume contained in the fluid, and improving the stability of the air intake device 1.

[0043] In a specific embodiment of the present application, the purification element 6 may include an adsorption purification material 61, which can remove oil smoke in the fluid by using the adsorption principle. The adsorption purification material 61 may specifically include at least one of activated carbon, silicate, aluminosilicate, activated alumina, silica gel, calcium carbide, carbon molecular sieve, polyacrylamide, and clay.

[0044] By providing an adsorption purification material 61 in the purification component 6, the oil fume in the fluid passing through the purification component 6 can be adsorbed, thereby achieving the effect of removing the oil fume therein, reducing the oil fume content in the fluid entering the output liquid path 52 through the purification component 6, and reducing the probability of the output liquid path 52 and the spray component 31 being blocked by oil fume, and effectively maintaining the oil fume removal ability of the fluid, which can improve the availability of the air intake device 1.

[0045] Optionally, the principle of removing oil smoke by fluid may be condensation, where the fluid contacts the oil smoke in the first aerosol 7 through the spray element 31, thereby cooling the oil smoke in the first aerosol 7 and condensing it into larger solid particles or liquid droplets, which can fall to the bottom of the spray chamber 32 under the action of gravity and can leave the spray chamber 32 along with the fluid. The principle of removing oil smoke by fluid may also be adsorption, where the fluid contacts the oil smoke and can adsorb the oil smoke, causing the oil smoke to fall to the bottom of the spray chamber 32 along with the fluid and can be carried away from the spray chamber 32 by the fluid.

[0046] Optionally, the fluid may contain alkaline substances, flocculants, emulsifiers and other similar substances to help remove grease from the gas. Among them, the alkaline substances may include common alkaline substances such as sodium hydroxide and sodium bicarbonate. These alkaline substances have good degreasing capabilities, and adding them to the fluid helps to remove the oil smoke in the first aerosol 7. Flocculants can enhance the effect of the fluid in absorbing oil smoke, thereby improving the oil smoke removal effect of the suction device 1. When the oil smoke is not soluble in the fluid, for example, the fluid is a mixed system with water as a solvent, the emulsifier can help the oil smoke mix with the system, so that the oil smoke can be emulsified and leave the spray chamber 32 with the fluid, reducing the probability of oil smoke sticking to the inner wall of the spray chamber 32, causing blockage, adhesion, mildew, deterioration and other adverse conditions, and can improve the availability of the suction device 1.

[0047] See also Figure 6 , Figure 6A schematic diagram of a cross-sectional structure of an embodiment of a purification component provided by the present invention. In a specific embodiment of the present application, the purification component 6 may further include a static chamber 62. The fluid may include water. The purification component 6 is formed with an input port 621 connected to the collection liquid path 51, an output port 622 connected to the output liquid path 52, and a deposition portion 623 on the inner wall facing the static chamber 62. In the vertical direction, the adsorption purification material 61 may be at least arranged on the upper side surface of the purification component 6 forming the static chamber 62, and the deposition portion 623 is arranged on the lower side surface of the purification component 6 forming the static chamber 62, and the height of the output port 622 is higher than the height of the deposition portion 623.

[0048] The mixture of fluid and oil smoke can be deposited and stratified after being left standing in the static chamber 62. Heavier substances in the oil smoke, such as tar, will be deposited in the sedimentation part 623 of the static chamber 62, while substances with lower density in the oil smoke, such as grease, will float on the upper layer of the fluid, allowing the adsorption and purification material 61 arranged on the upper side of the static chamber 62 to be adsorbed.

[0049] In addition, the structure provided in this embodiment sets the input port 621 of the purification component 6 connected to the collection liquid path 51 at a higher position, and sets the adsorption purification material 61 accordingly, so that the adsorption purification material 61 can adsorb the fluid entering the purification component 6 through the input port 621, thereby removing the oil smoke therein. In addition, the height of the output port 622 is higher than the height of the deposition part 623, so that the fluid in the middle layer after the oil smoke is naturally stratified can enter the output liquid path 52 through the output port 622, thereby separating the oil smoke from the fluid by using the different density properties of the mixture, and then effectively removing the oil smoke in the fluid, so that the fluid can continue to be used in the oil smoke removal cycle process.

[0050] See also Figure 4 , Figure 4 This is a schematic diagram of a cross-sectional structure of another embodiment of the device body provided by the present invention. In a specific embodiment of the present application, the inner wall of the fluid adsorption component 3 forming the spray chamber 32 may be provided with a guide groove 33, and the bottom of the guide groove 33 is connected to the end of the circulation pipeline 5 away from the spray part 31. In the vertical direction, the guide groove 33 is lower than the spray chamber 32, and the radial dimension of the guide groove 33 gradually decreases from high to low, forming a drainage surface 331 facing the spray chamber 32.

[0051] Through the structure provided in this embodiment, the guide groove 33 can be used to drain the fluid that falls to the bottom of the spray chamber 32, so that the fluid can flow along the drainage surface 331 to the circulation pipeline 5, thereby realizing the recycling of the fluid, reducing the probability of the fluid being deposited somewhere in the spray chamber 32 and causing blockage, bacterial growth and other adverse conditions, and improving the availability of the suction equipment 1.

[0052] In a specific embodiment of the present application, the spraying member 31 is provided with a nozzle 311, and the nozzle 311 can be arranged vertically upward. Thus, the fluid can be sprayed upward, and the fluid has an initial velocity upward after being sprayed from the nozzle 311, so that the fluid can decelerate upward to contact the first aerosol 7 for the first time, but the fluid is always affected by gravity, so its upward velocity will gradually decrease to a downward velocity, so that the fluid can accelerate downward and contact the first aerosol 7 for the second time, so that the fluid can fully contact the first aerosol 7, thereby improving the effect of the fluid in removing oil stains in the first aerosol 7.

[0053] In a specific embodiment of the present application, the number of the spraying parts 31 can be multiple. The multiple spraying parts 31 can be evenly arranged in the spraying chamber 32. The multiple spraying parts 31 are arranged at different positions in the spraying chamber 32, which is conducive to spraying the first aerosol 7 comprehensively, thereby effectively removing the oil smoke therein and reducing the oil smoke content in the second aerosol 8. The multiple spraying parts 31 can be evenly arranged in the spraying chamber 32, which can improve the comprehensiveness of oil smoke removal.

[0054] See also Figure 5 , Figure 5 A schematic cross-sectional view of an embodiment of a fluid adsorption assembly 3 provided by the present invention. In a specific embodiment of the present application, a winding passage 321 may be formed in the spray chamber 32, the first aerosol 7 and the second aerosol 8 move in the spray chamber 32 along the winding passage 321, and a plurality of spray elements 31 are evenly arranged along the winding passage 321. Figure 5 Only one possible arrangement of the coiled tubing 321 is shown.

[0055] Through the structure provided in this embodiment, the coiled pipeline formed in the spray chamber 32 can increase the travel of the first aerosol 7 in the spray chamber 32, and multiple spray parts 31 are arranged along the way, so that the first aerosol 7 can fully contact with the fluid sprayed by the spray parts 31, improve the oil fume removal effect of the air suction device 1, and further reduce the oil fume content in the second aerosol 8. In addition, the coiled pipeline is formed in the limited space in the spray chamber 32, which can narrow the passage of the first aerosol 7, so that the spray range of the spray part 31 can effectively cover the first aerosol 7 passing through the area, so that the first aerosol 7 can fully contact with the fluid, and further reduce the oil fume content in the second aerosol 8.

[0056] In a specific embodiment of the present application, the end of the inhalation channel 21 away from the fluid adsorption component 3 may be provided with a first inlet 211, and the end of the discharge channel 22 away from the fluid adsorption component 3 may be provided with a first outlet 221. The first inlet 211 and the first outlet 221 are connected to the room. The first aerosol 7 enters the inhalation channel 21 through the first inlet 211, and the second aerosol 8 is discharged back to the room through the first outlet 221.

[0057] Through the structure provided in this embodiment, the first aerosol 7 containing oil smoke in the room can be inhaled through the suction channel 21, and the second aerosol 8 with a lower oil smoke content after treatment can be discharged back into the room, so that the second aerosol 8 can be used to balance the air pressure difference between indoor and outdoor, alleviate the phenomenon of excessive indoor and outdoor air pressure difference caused by pumping a large amount of indoor aerosol to the outdoors, thereby reducing the probability of adverse situations such as smoke backflow, and improving the availability of the suction device 1.

[0058] Optionally, the fluid adsorption component 3 may further include a compressor. The compressor is used to cool down at least one of the structures such as the fluid, the spraying member 31, the spraying chamber 32, and the purification member 6, so as to cool down the first aerosol 7 and the oil smoke therein, so that the oil smoke can be condensed, thereby achieving the effect of removing the oil smoke in the first aerosol 7 and outputting the second aerosol 8 with a lower oil smoke content to the exhaust channel 22, which can improve the oil smoke removal effect of the suction device 1.

[0059] Optionally, the fluid adsorption component 3 may further include a centrifuge. The centrifuge may be arranged corresponding to the purification component 6, and is used to drive the purification component 6 to perform centrifugal motion, so as to separate different substances in the fluid in the purification component 6 by using centrifugal force. The inner wall of the purification component 6 may be provided with an adsorption material, and the oil smoke thrown to the inner wall of the purification component 6 under the centrifugal action can be directly adsorbed by the adsorption material, thereby achieving the effect of promoting the removal of oil smoke in the fluid and improving the usability of the suction device 1.
