[0034] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the present invention can be combined interchangeably without conflicting with each other.

[0035] Reference Figure 1 The range hood in this embodiment includes a first outer wall 110 and a second outer wall 120. The first outer wall 110 and the first panel 111 enclose a first installation cavity 130. A second installation cavity 140 is formed in the second outer wall 120. The first installation cavity 130 is connected with the second installation cavity 140 to form a flue 150. A first air inlet 1111 is provided on the first panel 111, and an air outlet 121 is provided on the second outer wall 120, so that the two ends of the flue 150 are respectively connected with the first air inlet 1111 and the air outlet 121. Therefore, when the oil smoke enters from the first air inlet 1111, it can be quickly discharged from the air outlet 121 through the flue 150, thereby improving the exhaust efficiency of the oil smoke.

[0036] Preferably, the flue 150 in this embodiment is in an oblong shape, and its cross-section can be set to be circular or rectangular. The oil smoke entering the flue 150 is directly discharged from the air outlet 121 under the action of the airflow inside the range hood, avoiding the irregular collision of oil smoke particles inside the range hood and adhering to the inside of the range hood, thereby increasing the noise and vibration of the range hood and affecting the performance of the range hood.

[0037] Combination Figure 2-Figure 3The first outer wall 110 and the second outer wall 120 are integrally connected to form the range hood body 100. A centrifugal fan (not shown) is arranged in the second installation cavity 140. The airflow generated by the rotation of the centrifugal fan allows the oil smoke in the first installation cavity 130 to quickly pass through the flue 150 into the second installation cavity 140 and be discharged from the air outlet 121 to achieve oil smoke purification. The range hood in this embodiment is also provided with a range hood housing 200. The range hood body 100 is installed in the range hood housing 200. The range hood body 100 and the range hood housing 200 are connected by a plurality of flexible installation components 210 to achieve flexible installation of the range hood body 100 and the range hood housing 200. The second installation cavity 140 is the main vibration and noise source of the range hood. Therefore, the flexible installation between the two can prevent the vibration of the range hood body 100 from being transmitted to the range hood housing 200, thereby increasing the vibration and noise of the range hood.

[0038] Specific, combined Figure 4 The flexible installation assembly 210 includes a shock absorber 211 and a fixing screw 212. The two sides of the shock absorber 211 are in close contact with the range hood body 100 and the range hood housing 200 respectively. The fixing screw 212 passes through the range hood body 100, the shock absorber 211 and the range hood housing 200 in sequence, and the three are locked by the fixing screw 212. Since the shock absorber 211 is provided between the range hood body 100 and the range hood housing 200, the vibration of the range hood body 100 is absorbed by the shock absorber 211 and cannot be transmitted to the range hood housing 200, thereby achieving the effect of shock reduction and noise reduction. Preferably, the flexible mounting assembly 210 also includes a gasket 213, which is covered between the outer peripheral surface of the fixing screw 212 and the range hood body 100 and between the fixing screw 212 and the range hood shell 200, thereby realizing a flexible connection between the fixing screw 212 and the range hood shell 200 and between the fixing screw 212 and the range hood body 100 in the radial direction of the fixing screw 212, further enhancing the shock absorbing effect of the flexible mounting assembly 210 and optimizing the performance of the range hood. The gasket 213 and the shock absorbing body 211 can be made of silicone material.

[0039] The range hood in this embodiment is also provided with a plurality of rigid mounting components 220, Figure 5The range hood body 100 is fixedly connected to a fixed wall (the fixed wall may be a wall or other fixed building) through a rigid mounting assembly 220 to achieve a rigid connection between the range hood body 100 and the fixed wall, so that the vibration of the range hood body 100 is transmitted to the fixed wall through the rigid mounting assembly 220, thereby preventing the range hood body 100 from resonating with the range hood housing 200, thereby achieving the effect of shock absorption and noise reduction. Specifically, the rigid mounting assembly 220 includes a locking screw 221, which passes through the range hood body 100, the outer wall and the fixed wall. The range hood body 100 can be installed on the wall by tightening the locking screw 221. The rigid mounting assembly 220 also includes a filling piece 222, which may be made of plastic material. The filling piece 222 is arranged between the outer peripheral surface of the locking screw 221 and the fixed wall. By arranging the filling piece 222, the contact between the locking screw 221, the range hood body 100 and the fixed wall is made closer, thereby improving the rigid connection strength between the range hood body 100 and the fixed wall.

[0040] Reference Figure 1 The range hood in this embodiment is further provided with a second panel 112, which is arranged in parallel with or parallel to the first panel 111, and a certain gap is provided between the second panel 112 and the first panel 111, so that an air duct 113 is formed between the first panel 111 and the second panel 112, and a second air inlet 1121 is provided on the second panel 112, which is connected with the first air inlet 1111. Under the action of the wind flow, the oil fume particles outside the range hood enter the air duct 113 from the second air inlet 1121, and the flow direction of the oil fume particles in the air duct 113 is irregular. After encountering the first panel 111 and the second panel 112, the oil fume particles adhere to the side walls of the first panel 111 and the second panel 112, and the oil fume particles that are not adhered enter the flue 150 from the first air inlet 1111 and are discharged from the air outlet 121. In this embodiment, the second panel 112 is detachably connected to the first panel 111. After removing the second panel 112, the first panel 111 and the second panel 112 can be conveniently cleaned to remove oil stains on their surfaces. The cleaning process is simple, fast, and repeatable, which improves the practicality of the range hood. The first panel 111 and the second panel 112 can be made of glass, which is easy to clean and prevents the situation where oil stains adhere too firmly and are difficult to remove.

[0041] Preferably, combined Figure 6In this embodiment, the second panel 112 and the first panel 111 can also be connected by a hinge 114. The second panel 112 can be rotated based on the hinge 114, so that the second panel 112 can be opened or closed relative to the first panel 111. When the second panel 112 is opened relative to the first panel 111, the movable range between the first panel 111 and the second panel 112 is increased, and the first panel 111 and the second panel 112 can be cleaned. After cleaning, the second panel 112 can be returned to the closed position. The first panel 111 and the second panel 112 can be cleaned without disassembling the second panel 112, and the operation is more convenient.

[0042] Preferably, two second air inlets 1121 may be provided on the second panel 112 to facilitate the oil smoke particles to enter the interior of the range hood from the second air inlets 1121 , and the shape of the first air inlet 1111 may be set to be circular.

[0043] Reference Figure 3 Combined with Figure 7 In this embodiment, an air supply device 300 is also provided. The air supply device 300 is installed on the first outer wall 110 and is located above the first panel 111 and the second panel 112. The air supply device 300 includes an air supply chamber 320. A rotatable air supply body 310 is provided in the air supply chamber 320. When the air supply body 310 rotates, an air flow can be generated, so that a directional wind flow is formed between the air supply chamber 320 and the second air inlet 1121, so that the irregularly moving oil fume particles outside the range hood follow the directional wind flow and quickly enter the air duct 113 from the second air inlet 1121, and further enter the flue 150 from the first air inlet 1111 and are discharged from the air outlet 121, thereby achieving oil fume purification and improving the degree and efficiency of oil fume adsorption.

[0044] Preferably, in this embodiment, the air supply body 310 is a wind wheel with blades or a cross-flow wind wheel, and a plurality of air supply bodies 310 may be provided in the air supply cavity 320 .

[0045] Reference Figure 1 An adsorption net 114 is provided in the first installation cavity 130. The adsorption net 114 can adsorb the oil smoke entering from the first air inlet 1111. In this embodiment, two adsorption nets 114 are arranged side by side and in parallel. The adsorption net 114 is connected to a conductive device, so that an electric field is formed around the adsorption net 114. When the oil smoke particles enter from the first air inlet 1111, they are adsorbed on the surface of the adsorption net 114 under the action of the electric field, thereby achieving the adsorption effect of the adsorption net 114 on the oil smoke.

[0046] In this embodiment, a driving device 115 is also provided, and the driving device 115 can be set as a driving motor. A rotating shaft 1141 is provided at the center of the adsorption net 114, and the rotating shaft 1141 is connected to the driving device 115 and rotates under the drive of the driving device 115, thereby driving the adsorption net 114 to rotate. A circle of dirt collecting grooves 116 is arranged along the edge of the adsorption net 114, and a certain gap is arranged between the inner wall of the dirt collecting grooves 116 and the outer edge of the adsorption net 114. During the rotation of the adsorption net 114, the oil smoke particles adhered to the adsorption net 114 are separated from the adsorption net 114 under the action of centrifugal force, fall downward and are thrown onto the inner wall of the dirt collecting groove 116, completing the transfer of oil smoke between the adsorption net 114 and the dirt collecting groove 116, avoiding the long-term accumulation of oil smoke on the adsorption net 114, affecting the adsorption performance of the adsorption net 114, and facilitating the collection and treatment of oil pollution.

[0047] A dirt-cleaning member 117 is also provided, which contacts the inner wall of the dirt-collecting tank 116 and can rotate relative to the dirt-collecting tank 116. During the rotation, the dirt-cleaning member 117 scrapes off the oily dirt adhering to the inner wall of the dirt-collecting tank 116, thereby cleaning the dirt-collecting tank 116. A dirt-collecting box 118 is provided below the dirt-cleaning member 117, and the oily dirt scraped off by the dirt-cleaning member 117 falls from the dirt-cleaning member 117 into the dirt-collecting box 118, so that the oily dirt can be treated more thoroughly, and the dirt-collecting capacity of the dirt-collecting box 118 can be maintained by regularly cleaning the oily dirt in the dirt-collecting box 118.

[0048] Reference Figure 1 Combined with Figure 8 Preferably, the cleaning member 117 is provided with a cleaning section 1171 and an oil guiding section 1172, the cleaning section 1171 is integrally connected with the oil guiding section 1172, the cleaning section 1171 is in contact with the inner wall of the dirt collecting tank 116, and the oil guiding section 1172 is inclined downward relative to the dirt collecting tank 116. Therefore, the oil scraped off by the cleaning section 1171 drips along the oil guiding section 1172 under the action of gravity and is collected in the dirt collecting box 118, thereby improving the treatment efficiency of the oil.

[0049] Reference Figure 1In this embodiment, a cleaning device 400 is further provided. The cleaning device 400 includes a nozzle 410 capable of spraying cleaning liquid onto the adsorption net 114. During the rotation of the adsorption net 114, different parts of the adsorption net 114 are cleaned by the cleaning liquid, so that the oil stains adhered to the adsorption net 114 are decomposed or fall into the sump 116, thereby cleaning the oil stains on the adsorption net 114. Specifically, the cleaning device 400 also includes a cleaning bottle 420 for accommodating cleaning liquid, a water inlet pipe 430, a water pump 440 and a water outlet pipe 450. The two ends of the water inlet pipe 430 are respectively connected to the cleaning bottle 420 and the water pump 440, and the two ends of the water outlet pipe 450 are respectively connected to the water pump 440 and the nozzle 410. The cleaning liquid in the cleaning bottle 420 enters the water inlet pipe 430 driven by the water pump 440 and passes into the water outlet pipe 450 through the water pump 440, and is finally sprayed out from the nozzle 410 to clean the adsorption net 114, thereby improving the adsorption efficiency and service life of the adsorption net 114.

[0050] Reference Figure 7 Combined with Fig. 9 In this embodiment, a detection device 500 is also provided. The detection device 500 is installed on the housing 200 of the range hood. The detection device 500 includes a base 510 and a plurality of detection units 520. The detection units 520 are detachably connected to the base 510. The base 510 is installed on the first outer wall 110. A socket 511 is provided on the base 510. A plug 521 is provided on the detection unit 520. The plug 521 can be inserted into the socket 511 to achieve electrical conduction of the detection unit 520 and ensure the normal operation of the detection unit 520. After a period of use of the detection unit 520, the oil smoke entering the detection unit 520 will affect the detection accuracy of the detection unit 520. Therefore, the detection efficiency of the detection unit 520 can be maintained by replacing the detection unit 520. The setting of the plug 521 and the socket 511 optimizes the interchangeability of the detection device 500 and has good practicality. Preferably, the detection unit 520 in this embodiment includes a smoke detection unit for detecting smoke concentration, a combustible gas detection unit for detecting combustible gas concentration, and a human infrared detection unit for detecting a human body. Through the above-mentioned detection unit 520, the smoke and combustible gas concentrations in the kitchen environment can be detected and an alarm can be issued when the concentration reaches a set value. It can also detect people entering the kitchen environment. When a human body is detected entering, oil or oil fume purification can be automatically performed, thereby improving the flexibility of using the range hood.
