[0028] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0029] This utility model discloses a range hood. Figures 1 to 5 The range hood includes a range hood body 1 and an oil cup 2. The range hood body 1 has a top plate 11 and an air collecting chamber located above the top plate 11. The top plate 11 is provided with an air intake 111 and an oil dripping hole 112, which are connected to the air collecting chamber; the oil cup 2 is movably connected to the top plate 11, and has a accommodating chamber with an opening facing upward; wherein, when the range hood is turned off, the downward projections of the air intake 111 and the oil dripping hole 112 fall into the opening of the accommodating chamber; when the range hood is started, the oil cup 2 slides along the top plate 11, and makes the downward projection of the oil dripping hole 112 fall into the opening of the accommodating chamber, and the downward projection of the air intake 111 falls outside the opening of the accommodating chamber.

[0030] In this embodiment, the air intake 111 is located at the rear end of the top plate 11, relatively close to the wall, and vertically diagonally above the gas outlet of the stove. A smoke exhaust fan is installed in the air collection chamber. When the smoke exhaust fan is in operation, the air intake 111 generates negative pressure. The oil smoke generated by the user's cooking is sucked into the air collection chamber through the air intake 111 and finally exhausted by the smoke exhaust fan. The oil cup 2 can be installed below the range hood body 1, that is, below the oil drip hole 112. During the process of exhausting oil smoke from the range hood, the oil and water mixture in the oil smoke forms oil liquid, which accumulates in the air collection chamber and on the volute of the smoke exhaust fan. The oil liquid eventually flows through the oil drip hole 112 to the oil cup 2 to achieve oil collection. The oil cup 2 is movable relative to the top plate 11, that is, it is movable relative to the air intake 111 on the top plate 11. The oil cup 2 can open or cover the air intake 111 by sliding.

[0031] When the range hood is started, Figure 2 As shown, oil cup 2 opens air intake 111 to allow oil smoke to be normally drawn into the air collection chamber. As the oil smoke flows through air intake 111 into the air collection chamber, the oil-water mixture in the oil smoke adheres to air intake 111. When the range hood is in operation, the smoke exhaust fan creates a negative pressure in the air collection chamber, preventing the oil adhering to air intake 111 from dripping downward. At this time, the downward projection of oil drip hole 112 falls into the opening of the accommodating chamber of oil cup 2, allowing the oil accumulated in the air collection chamber and on the volute of the smoke exhaust fan to flow normally into oil cup 2.

[0032] When the cigarette lighter is turned off, Figure 6As shown, when the exhaust fan stops operating and the oil cup 2 blocks the air intake 111, the oil adhering to the air intake 111 drips from the air intake 111 after its gravity overcomes the adhesive force and is caught by the oil cup 2, preventing the oil from dripping onto the stove or the user's cookware. This prevents the oil from dripping out of the air intake 111 and onto the stove, affecting the user experience. Furthermore, when the range hood is turned off, blocking the air intake 111 with the oil cup 2 prevents insects and other foreign matter from entering the range hood and affecting its internal components, thereby improving the stability of the range hood's internal structure. Furthermore, while the oil cup 2 blocks the air intake 111, the downward projection of the oil drip hole 112 can also fall into the opening of the oil cup 2's accommodating chamber, ensuring that oil accumulated in the air collecting chamber and on the volute of the exhaust fan can still flow into the oil cup 2 normally.

[0033] In the smoke machine of the present invention, Figure 1 As shown, the air intake 111 is located in front of the oil drip hole 112. When the range hood is started, the oil cup 2 slides backward along the top plate 11, and the downward projection of the air intake 111 falls outside the opening of the accommodating cavity. In the range hood of the present invention, the air intake 111 is located behind the oil drip hole 112. After the oil cup 2 is hung on the top plate 11, when the range hood is in operation, the oil cup 2 moves backward, exposing the air intake 111. At this time, the air intake 111 is located in front of the oil cup 2. When the exhaust fan of the range hood is in operation, the oil smoke generated by the user's cooking flows toward the air intake 111. Since the oil cup 2 is located behind the air intake 111, it will not hinder the oil smoke from flowing toward the air intake 111. In the range hood of the present invention, the width of the opening of the oil cup 2's accommodating cavity along the front-to-back direction is greater than or equal to the sum of the width of the oil drip hole 112 along the front-to-back direction, the width of the air intake 111 along the front-to-back direction, and the distance between the oil drip hole 112 and the air intake 111. Thus, when the oil cup 2 blocks the air intake 111, the downward projections of both the oil drip hole 112 and the air intake 111 fall into the opening of the oil cup 2's accommodating cavity. This allows the oil cup 2 to simultaneously receive oil dripping from both the oil drip hole 112 and the air intake 111 when the range hood is turned off.

[0034] The range hood of this invention also includes a drive assembly 3. The output end of the drive assembly 3 is connected to the oil cup 2, which is used to drive the oil cup 2 along the top plate 11. When the range hood is turned on, the control unit controls the drive assembly 3 to operate, thereby promptly driving the oil cup 2 backward to expose the air intake 111. When the range hood is turned off, the control unit controls the drive assembly 3 to operate in reverse, thereby promptly driving the oil cup 2 to block the air intake 111. This allows for automatic actuation of the oil cup 2, improving the convenience of use of the range hood.

[0035] In the range hood of the present invention, a guide groove 113 is provided on the top plate 11. The output end of the drive assembly 3 is connected to the connector 4. One end of the connector 4 is connected to the output end of the drive assembly 3, and the other end passes through the guide groove 113 to connect to the oil cup 2. The drive assembly 3 is mounted above the top plate 11 and connected to the connector 4. The guide groove 113 is used to allow the connector 4 to pass under the top plate 11 and then connect to the oil cup 2 located below the top plate 11. When the drive assembly 3 is activated, the drive assembly 3 drives the connector 4 to slide within the guide groove 113, which in turn drives the oil cup 2 to move, effectively driving the oil cup 2. It will be understood that the length of the guide groove 113 in the front-to-back direction is greater than or equal to the maximum travel distance of the oil cup 2 to ensure that the oil cup 2 can move into position.

[0036] In the smoke machine of the present invention, Figure 3 and Figure 4 As shown, the connector 4 is connected to an oil cup hanger 41. Oil cup lugs 21 are provided on both sides of the oil cup 2. The lugs 21 are detachably connected to the oil cup hangers 41. There are two connectors 4 and two guide slots 113. The locations of the two connectors 4 and the two guide slots 113 correspond to the locations of the oil cup lugs 21. Each connector 4 is connected to an oil cup hanger 41. The two connectors 4 extend through the two guide slots 113 to the underside of the top plate 11. The oil cup hangers 41 are connected to the portion of the connector 4 located below the top plate 11. The oil cup lugs 21 are detachably connected to the oil cup hangers 41, achieving a detachable connection between the oil cup 2 and the connector 4. This allows the user to remove the oil cup 2 from the top plate 11, discard the oil, and clean it, then reinstall it. The oil cup hanging ear 21 is provided on the inner wall surface of the oil cup 2 so that the oil cup 2 can shield the oil cup hanging ear 21 and the oil cup hanger 41 , thereby improving the appearance integrity of the range hood.

[0037] In the smoke machine of the present invention, Figure 7 As shown, the drive assembly 3 includes a driver 31, a transmission member, and a guide member. The output end of the driver 31 is connected to the transmission member, which slides along the guide member. The connector 4 is connected to the transmission member. The driver 31 provides driving power, and the transmission member converts and transmits the power output by the driver 31 to the connector 4, thereby driving the oil cup 2 through the connector 4. The guide member extends in the front-to-back direction and guides the movement of the driver 31, preventing the driver's motion trajectory from deviating, thereby preventing the movement trajectory of the oil cup 2 from deviating and ensuring the stability of the movement of the oil cup 2.

[0038] In the smoke machine of the present invention, Figure 7As shown, the driving member 31 adopts a reduction motor, which is arranged on the upper surface of the top plate 11. The transmission member includes a transmission gear 32 and a rack 33. The transmission gear 32 is connected to the output end of the reduction motor, and the rack 33 is engaged with the transmission gear 32. The guide member includes a slide 34, which is arranged on the upper surface of the top plate 11. The rack 33 is slidably connected to the slide 34, and the connecting member 4 is connected to the rack 33.

[0039] The reduction motor refers to an integrated body of a reducer and an electric motor. The output speed of the reduction motor can be adjusted according to actual needs. By controlling the output speed of the reduction motor, the moving speed of the oil cup 2 can be controlled. The transmission gear 32 cooperates with the rack 33 to convert the rotation of the output end of the reduction motor into the linear motion of the rack 33, so that the rack 33 drives the oil cup 2 to move linearly through the connecting piece 4. For example, when the output end of the reduction motor rotates forward, it can drive the oil cup 2 to move backward to open the air suction port 111. When the output end of the reduction motor is reversed, it can drive the oil cup 2 to move forward to block the air suction port 111. The slide 34 extends in the front-to-back direction. The slide 34 can guide the linear movement process of the rack 33 to prevent the movement trajectory of the rack 33 from deviating.

[0040] In the smoke machine of the present invention, Figure 7 As shown, the guide member further includes a slide bar 35, which is slidably connected to the slide seat 34. The rack 33 is connected to the slide bar 35, and the connector 4 is provided at the rear end of the slide bar 35. The slide bar 35 and the slide seat 34 slide together to increase the mating area between the guide member and the slide seat 34, thereby improving the mating stability of the guide member and the slide seat 34, thereby improving the stability of the guiding process of the oil cup 2.

[0041] In the smoke machine of the present invention, Figure 1 and Figure 5 As shown, the front side of the oil cup 2 is tilted backward from top to bottom, maximizing the cross-sectional area of ​​the opening of the oil cup 2's accommodating chamber. The distance between the front and rear sides of the oil cup 2 gradually decreases from top to bottom, so that the width of the oil cup 2's accommodating chamber decreases downward from the opening. This ensures that the opening of the oil cup 2's accommodating chamber remains wide enough to ensure that the downward projections of the oil drip hole 112 and the air intake 111 both fall within the opening of the oil cup 2's accommodating chamber when the oil cup 2 blocks the air intake 111. This allows the oil cup 2 to simultaneously receive oil dripping from both the oil drip hole 112 and the air intake 111 when the range hood is turned off. Furthermore, the overall volume of the oil cup 2 can be rationally controlled, reducing the space occupied by the oil cup 2 in the kitchen.

[0042] In the range hood of the present invention, the oil cup 2 includes a front wall, a rear wall, a left wall, and a right wall. The front wall is tilted backward from top to bottom, and the lower edge of the front wall is connected to the lower edge of the rear wall. The left wall and the right wall are connected between the front wall and the rear wall on the corresponding side. The front wall and the rear wall are arranged in a rectangular shape, and the left wall and the right wall are arranged in a triangular shape. The rear wall extends vertically so that when the oil cup 2 moves backward to open the air intake 111, the rear wall can be close to the wall. The front wall, the rear wall, the left wall, and the right wall enclose a accommodating chamber for the oil cup 2, and the upper edge of the front wall, the upper edge of the rear wall, the upper edge of the left wall, and the upper edge of the right wall enclose an opening of the accommodating chamber.

[0043] The distance between the front and rear side walls gradually decreases from top to bottom, so that the width of the oil cup 2's accommodating cavity decreases downward from the opening. This ensures that the opening of the oil cup 2's accommodating cavity remains wide enough to ensure that the downward projections of both the drip hole 112 and the air intake 111 fall within the opening of the oil cup 2 when the oil cup 2 blocks the air intake 111. This allows the oil cup 2 to simultaneously receive oil dripping from both the drip hole 112 and the air intake 111 when the range hood is turned off. Furthermore, the overall volume of the oil cup 2 can be rationally controlled, reducing the space occupied by the oil cup 2 in the kitchen.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
