[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Reference Figures 1 to 6 This utility model discloses a range hood comprising a base 100, a fan assembly, a filter 200, and a locking mechanism 300. The base 100 has a suction duct 101, an air inlet 102 communicating with the suction duct 101 on its lower side, and an air outlet 103 communicating with the suction duct 101. The fan assembly is disposed on the base 100 and located within the suction duct 101, and is used to generate airflow from the air inlet 102 to the air outlet 103 within the suction duct 101. One end of the filter 200 is rotatably disposed on the base 100 and can cover or open the air inlet 102. The locking mechanism 300 is disposed between the base 100 and the filter 200; when the filter 200 covers the air inlet 102, the locking mechanism 300 can lock or unlock the position of the filter 200 relative to the base 100.

[0034] One end of the filter screen 200 is rotatably mounted on the base 100. When the locking mechanism 300 locks the position of the filter screen 200, the filter screen 200 can remain in the position of covering the air inlet 102. When it is necessary to open the air inlet 102, the locking mechanism 300 unlocks the position of the filter screen 200. At this time, the filter screen 200 can be flipped around one end to open the air inlet 102. At this time, the filter screen 200 remains suspended on the base 100, and the user does not need to move the filter screen 200 to a designated position. After cleaning and maintenance, the user can flip the filter screen 200 and cover the air inlet 102, and then use the locking mechanism 300 to lock the position of the filter screen 200 again. The user does not need to move the filter screen 200 and install it on the base 100, thus making the process of opening or closing the air inlet 102 of the filter screen 200 more convenient.

[0035] In this embodiment, the filter screen 200 is provided with a hook 210, and the base 100 is provided with a connector 110. The hook 210 is detachably connected to the connector 110 and can rotate relative to the connector 110. By connecting the hook 210 to the connector 110 and allowing the hook 210 to rotate relative to the connector 110, the filter screen 200 can rotate relative to the base 100. Furthermore, the hook 210 can be detached from the connector 110 to completely remove the filter screen 200 from the base 100, facilitating cleaning and maintenance of the filter screen 200 in certain situations. The structure is simple and the functionality is relatively versatile.

[0036] In this embodiment, the connector 110 is located on the wall of the air inlet 102. The connector 110 is a plate with a through hole 111 along the horizontal direction. The hook 210 passes through the through hole 111 and is hooked to the wall of the through hole 111. When the hook 210 passes through the through hole 111, the wall of the through hole 111 can restrict the vertical position of the hook 210, reducing the risk of the filter screen 200 being accidentally touched and shaken. The hook 210 can rotate around the wall of the through hole 111. When it is necessary to remove the filter screen 200, the filter screen 200 is moved until the hook 210 is dislodged from the through hole 111.

[0037] It is conceivable that in other embodiments, the connector 110 may also be a crossbeam, with the hook 210 hooked onto the crossbeam so that the hook 210 can rotate around the crossbeam, thereby allowing the filter screen 200 to rotate relative to the base 100; the hook 210 may also be disposed on the base 100, in which case the connector 110 is disposed on the filter screen 200.

[0038] It is conceivable that in other embodiments, the filter 200 may also be rotatably connected to the base 100 by other structures. For example, the base 100 is provided with a rotating shaft, and one end of the filter 200 is provided with a rotating shaft hole. The rotating shaft passes through the rotating shaft hole, so that one end of the filter 200 can be rotatably connected to the base 100.

[0039] In this embodiment, the locking mechanism 300 includes a limiting member and a limiting hole. The limiting hole is located on the base 100, and the limiting member is pivotally connected to the filter screen 200. When the filter screen 200 covers the air inlet 102, the limiting member can rotate to enter or disengage from the limiting hole. Specifically, the limiting member is a rotating buckle. The limiting member engages and disengages from the limiting hole by rotating, making the operation simple and the unlocking and locking of the filter screen 200 relatively convenient.

[0040] Specifically, the locking mechanism 300 also has a handle, which is connected to the limiting member to facilitate driving the limiting member to rotate.

[0041] Specifically, the limiting hole is located on the wall of the air inlet 102. The limiting component is an eccentric component. When the limiting component rotates, it can completely disengage from the limiting hole to unlock the position of the filter 200, or partially embed itself into the limiting hole to lock the position of the filter 200.

[0042] It is conceivable that in other embodiments, the locking mechanism 300 may also have other structures. For example, the locking mechanism 300 may include a screw, a through hole, and a threaded hole. The filter screen 200 is provided with a through hole, and the base 100 is provided with a threaded hole. The screw passes through the through hole and is threaded into the threaded hole, locking the filter screen 200 to the base 100. This locks the position of the filter screen 200 when it covers the air inlet 102. When the screw is removed, the filter screen 200 is allowed to rotate. Alternatively, the locking mechanism 300 may be a pin. Both the base 100 and the filter screen 200 may have pin holes. When the filter screen 200 covers the air inlet 102, the pin holes of the base 100 and the filter screen 200 are aligned, and the pin is inserted into the two pin holes, thereby locking the position of the filter screen 200 relative to the base 100. When the pin is pulled out, the filter screen 200 is allowed to rotate relative to the base 100.

[0043] In this embodiment, the base 100 is provided with an oil receiving component 400, which has an oil receiving groove. When the filter screen 200 covers the air inlet 102, the filter screen 200 is tilted downwards, with one end of the filter screen 200 being the lowest point. The oil receiving groove is located below one end of the filter screen 200. When the range hood is in use, the filter screen 200 covers the air inlet 102. When high-temperature oil fumes come into contact with the filter screen 200, waste oil droplets will condense on the filter screen 200. Due to the tilt of the filter screen 200, the waste oil droplets will flow and collect towards the lowest point of the filter screen 200 under the action of gravity. At this time, the oil receiving groove can receive the waste oil droplets dripping from the lowest point of the filter screen 200, avoiding hygiene problems caused by waste oil droplets dripping everywhere. Moreover, the collection of waste oil droplets is more convenient, and the volume of the oil receiving groove can be made smaller, making the range hood structure more compact.

[0044] In this embodiment, the filter screen 200 is hollow and has a hollow cavity 220. One end of the filter screen 200 is provided with an oil outlet hole communicating with the hollow cavity 220, and the oil outlet hole is located above the opening of the oil collecting tank. The hollow cavity 220 of the filter screen 200 helps to increase the heat exchange area between the filter screen 200 and the oil fumes, allowing the oil fumes to condense into waste oil droplets at the filter screen 200 more effectively. The waste oil droplets remaining in the hollow cavity 220 can also flow to the bottom of the filter screen 200 under the action of gravity and leave the hollow cavity 220 through the oil outlet hole to enter the oil collecting tank for collection.

[0045] In this embodiment, the base 100 is provided with an oil collection tank 112. One end of the filter screen 200 is rotatably connected to one side of the oil collection tank 112. An oil passage hole 113 is provided at the bottom of the oil collection tank 112, located above the opening of the oil receiving tank. The oil collection tank 112 can collect waste oil droplets dripping from the suction duct 101, and the oil passage hole 113 allows the waste oil droplets in the oil collection tank 112 to flow into the oil receiving tank for unified recycling. The structure is simple, and the recovery rate of waste oil droplets is further improved. Furthermore, the oil collection tank 112 also has the function of rotatably connecting with the filter screen 200, resulting in a compact structure and good performance. Specifically, the oil collection tank 112 is provided on the connector 110, and is formed in the side wall of the oil collection tank 112 through a hole 111.

[0046] In this embodiment, the oil receiving component 400 is detachably mounted on the base 100. The oil receiving component 400 is detachable, allowing for easy removal and cleaning once the waste oil droplets are collected. Furthermore, since the oil receiving component 400 is located below the filter screen 200, its removal prevents obstruction during the downward flipping and opening process of the filter screen 200, facilitating its easy opening.

[0047] Specifically, the base 100 has a slot along the horizontal direction, and the oil receiving component 400 has a connector strip that inserts into the slot, allowing the oil receiving component 400 to be detachably installed on the base 100. It is conceivable that in other embodiments, the oil receiving component 400 can also be detachably connected to the base 100 through other structures. For example, the oil receiving component 400 may be equipped with a magnet, and the base 100 may be made of iron; the oil receiving component 400 can be magnetically attracted to the base 100, thus achieving a detachable connection between the oil receiving component 400 and the base 100.

[0048] In this embodiment, the base 100 is equipped with a control module and an ambient temperature detection module 500. The ambient temperature detection module 500 is electrically connected to the control module, and the control module is electrically connected to the fan assembly. The ambient temperature detection module 500 can detect the temperature of the cooking zone. When the temperature of the cooking zone rises, the ambient temperature detection module 500 can control the fan assembly to start or adjust the fan assembly's speed through the control module to automatically operate the cooking process without requiring manual operation of the range hood by the user, thus providing a physical basis for the intelligent operation of the range hood.

[0049] Specifically, the ambient temperature detection module 500 is an infrared temperature sensor, which offers fast detection speed, high accuracy, and ease of use. It is conceivable that the ambient temperature detection module 500 could also be other types of non-contact temperature sensors, which can be configured according to specific needs by those skilled in the art.

[0050] Specifically, the control module can be a circuit board, a microcontroller, or other circuit structure with control functions.

[0051] In this embodiment, the base 100 includes a smoke collection hood 120 and a bellows 130. The smoke collection hood 120 has a smoke collection chamber 121, and an air inlet 102 communicating with the smoke collection chamber 121 is provided on the lower side of the smoke collection hood 120. The bellows 130 has a suction chamber 131, and an air outlet 103 communicating with the suction chamber 131 is provided at the upper end of the bellows 130. A connecting hole 122 is provided on the upper side of the smoke collection hood 120. The lower end of the bellows 130 has an opening, and the lower end of the bellows 130 is connected to the periphery of the opening of the connecting hole 122. The smoke collection chamber 121 is connected to the suction chamber 131 through the connecting hole 122 to form a suction duct 101. The fan assembly is set inside the bellows 130. A limiting groove 123 is provided on the upper side of the smoke collection hood 120, and the connecting hole 122 is located at the bottom of the limiting groove 123. The lower end of the bellows 130 is embedded in the limiting groove 123. By embedding the lower opening of the bellows 130 into the limiting groove 123 and the connecting hole 122 being located at the bottom of the limiting groove 123, it is possible to assemble the bellows 130 and the smoke collection hood 120 without repeatedly manually aligning the positions of the bellows 130 and the connecting hole 122. The alignment of the bellows 130 and the connecting hole 122 is completed when the lower end of the bellows 130 is embedded into the limiting groove 123, making assembly relatively convenient.

[0052] Specifically, the fan assembly is a centrifugal fan with a volute casing. It is conceivable that in other embodiments, the fan assembly could also be, for example, an axial flow fan.

[0053] Specifically, the lower side of the fume hood 120 is equipped with a light to illuminate the cooking area. The side wall of the fume hood 120 is also equipped with a display panel to show the operating status of the range hood.
