[0027] 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:

[0028] The utility model discloses a range hood, such as Figures 1 to 4As shown, the range hood includes a range hood body 1, a movable baffle 2 and an oil cup 3. 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 suction port 111, which is connected to the air suction port 111; the movable baffle 2 is slidably connected to the bottom of the top plate 11, and the movable baffle 2 is used to open the air suction port 111 when the range hood is started, and to close the air suction port 111 when the range hood is turned off; the oil cup 3 is connected to the range hood body 1 and is connected to the air collecting chamber, and is used to receive the oil discharged from the air collecting chamber.

[0029] In this embodiment, the air intake 111 is located at the rear end of the top plate 11, which is relatively close to the wall, and is vertically located obliquely 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 can generate negative pressure. The oil smoke generated by the user's cooking is sucked into the air collection chamber through the air intake 11 and finally discharged by the smoke exhaust fan. The movable baffle 2 can move relative to the top plate 11, that is, it can move relative to the air intake 111 on the top plate 11. The movable baffle 2 can open or close the air intake 111 by sliding. When the range hood is started, the movable baffle 2 opens the air intake 111 so that the oil smoke can be normally sucked into the air collection chamber. In the process of the oil smoke flowing into the air collection chamber through the air intake 111, the oil and water mixture in the oil smoke will adhere to the air intake 111. When the range hood is in operation, the smoke exhaust fan forms a negative pressure in the air collection chamber, and the oil liquid adhering to the air intake 111 will not drip downward. When the range hood is turned off, the exhaust fan stops running and the movable baffle 2 closes the air inlet 111. The oil adhering to the air inlet 111 drips from the air inlet 111 after its gravity overcomes the adhesive force and is caught by the movable baffle 2, preventing the oil from dripping onto the stove or the user's cookware. This prevents the oil from dripping out of the air inlet 111 and onto the stovetop, thereby affecting the user experience. Furthermore, closing the air inlet 111 with the movable baffle 2 when the range hood is turned off prevents foreign matter such as insects from entering the range hood and affecting its internal components, thereby improving the stability of its internal structure. Closing the air inlet 111 with the movable baffle 2 when the range hood is turned off also improves the overall appearance of the range hood.

[0030] In the smoke machine of the present invention, Figure 3 and Figure 4As shown, the downward projection of the rear edge of the movable baffle 2 always falls into the accommodating cavity of the oil cup 3. In the illustrated embodiment, when the range hood is started, the movable baffle 2 moves backward to open the air intake 111, and when the range hood is turned off, the movable baffle 2 moves forward to close the air intake 111. It can be understood that whether the movable baffle 2 is in the position of opening the air intake 111 or closing the air intake 111, the downward projection of the rear edge of the movable baffle 2 always lies within the opening area of ​​the oil cup 3. In this way, oil dripping onto the movable baffle 2 through the air intake 111 can flow along the upper surface of the movable baffle 2 toward its rear edge, and finally flow into the oil cup 3 from the rear edge of the movable baffle 2. As a result, oil dripping onto the movable baffle 2 can be prevented from overflowing from other edges of the movable baffle 2, thereby reducing the impact on the cleanliness of the range hood surface and the cooking environment, and improving the performance of the range hood.

[0031] In the smoke machine of the present invention, Figures 3 to 5 As shown, the top plate 11 is also provided with an oil dripping hole 112, which is located at the rear side of the air intake port 111. The oil dripping hole 112 is connected to the air collecting chamber, and the oil cup 3 is connected to the bottom of the top plate 11, with the opening of its receiving chamber facing the oil dripping hole 112. The oil accumulated in the air collecting chamber will flow to the oil dripping hole 112 through the diversion structure, and finally drip into the receiving chamber of the oil cup 3 through the oil dripping hole 112, so as to realize the centralized collection of the oil. Since the oil dripping hole 112 is located at the rear side of the air intake port 111, after the oil cup 3 is connected to the top plate 11, the oil cup 3 is located at the rear side of the air intake port 111. When the oil smoke flows toward the air intake port 111, the oil cup 3 will not affect the oil smoke entering the air collecting chamber.

[0032] Since the oil dripping hole 112 is connected to the air collecting chamber, and there is inevitably an installation gap between the oil cup 3 and the top plate 11, when the range hood is started, if the oil dripping hole 112 is not covered, negative pressure is easily formed at the oil dripping hole 112, causing the external airflow to be sucked into the oil dripping hole 112; since the air inlet area of ​​the oil dripping hole 112 is small, it is easy to generate noise when the airflow passes through the oil dripping hole 112, affecting the user experience; and when the airflow enters the air collecting chamber through the oil dripping hole 112, the airflow will carry the oil upward, causing the oil to splash in the air collecting chamber, and the splashed oil may also splash out from the air inlet 111. In order to solve this problem, in the range hood of the present invention, if Figure 3 and Figure 4As shown, when the range hood is turned off, the movable baffle 2 closes the air intake port 111 and opens the oil dripping hole 112. When the range hood is started, the movable baffle 2 moves backward, opens the air intake port 111 and blocks the oil dripping hole 112. The movable baffle 2 can open or close the air intake port 111 by moving forward and backward. When the range hood is started, the movable baffle 2 can close the oil dripping hole 112 while opening the air intake port 111, that is, it is blocked between the opening of the accommodating cavity of the oil cup 3 and the oil dripping hole 112. In this way, when the smoke exhaust fan is started, the oil dripping hole 112 is blocked and the air intake port 111 is opened. While ensuring that oil smoke can enter the air collecting chamber through the air intake port 111, it can prevent air flow from entering the oil dripping hole 112 to reduce noise generation. It can also prevent the air flow entering the air collecting chamber through the oil dripping hole 112 from blowing the oil upward, causing the oil to splash and drip from the air intake port 111 to the outside of the range hood. When the smoke detector is turned off, the movable baffle 2 can open the oil dripping hole 112 while closing the air intake port 111 to ensure that the oil flowing out of the oil dripping hole 112 can flow smoothly into the oil cup 3. At the same time, when the movable baffle 2 closes the air intake port 111, the downward projection of the rear edge of the movable baffle 2 falls into the accommodating cavity of the oil cup 3, so that the oil dripping from the upper surface of the movable baffle 2 drips into the oil cup 3.

[0033] In the smoke machine of the present invention, Figure 5 As shown, a groove is provided on the top plate 11, and the air inlet 111 and the oil dripping hole 112 are provided in the groove. The movable baffle 2 is slidably connected in the groove, and the lower surface of the movable baffle 2 is flush with the lower surface of the portion of the top plate 11 excluding the groove. Providing the movable baffle 2 in the groove can prevent the movable baffle 2 from additionally increasing the overall height of the range hood, thereby reasonably controlling the overall size of the range hood and reducing the space occupied. The lower surface of the movable baffle 2 is flush with the lower surface of the portion of the top plate 11 excluding the groove. When the movable baffle 2 closes the air inlet 111, the lower surface of the sliding baffle 2 is in the same plane as the other portions of the top plate 11 excluding the groove. When looking up at the top plate 11, the top plate 11 is flat, thereby making the overall outer surface of the range hood more visually flat, thereby improving the overall appearance of the range hood.

[0034] In the smoke machine of the present invention, Figure 6 As shown, the range hood also includes a drive assembly 4. The output end of the drive assembly 4 is connected to the movable baffle 2, which is used to drive the movable baffle 2 back and forth. When the range hood is turned on, the control unit controls the drive assembly 4 to operate, thereby promptly driving the movable baffle 2 to open the air intake 111. When the range hood is turned off, the control unit controls the drive assembly 4 to operate in reverse, thereby promptly driving the movable baffle 2 to close the air intake 111. This enables automatic actuation of the movable baffle 2, improving the convenience of the range hood.

[0035] In the smoke machine of the present invention, Figure 5 and Figure 6As shown, a guide slot 113 is provided on the top plate 11. The output end of the drive assembly 4 is connected to the connector 5. One end of the connector 5 is connected to the output end of the drive assembly 4, and the other end passes through the guide slot 113 and connects to the movable baffle 2. The drive assembly 4 is mounted above the top plate 11 and connected to the connector 5. The guide slot 113 is used to allow the connector 5 to pass through the bottom of the top plate 11 and then connect to the movable baffle 2 located below the top plate 11. When the drive assembly 4 is activated, the drive assembly 4 drives the connector 5 to slide within the guide slot 113, and the guide slot 113 drives the movable baffle 2 to move, thereby effectively driving the movable baffle 2. It will be understood that the length of the guide slot 113 along the front-to-back direction is greater than or equal to the maximum travel range of the movable baffle 2 to ensure that the movable baffle 2 can move into place.

[0036] In the smoke machine of the present invention, Figure 6 As shown, the drive assembly 4 includes a driver 41, a transmission member, and a guide member. The output end of the driver 41 is connected to the transmission member, which slides along the guide member. The connector 5 is connected to the transmission member. The driver 41 provides driving power, and the transmission member converts and transmits the power output by the driver 41 to the connector 5, thereby driving the movable baffle 2 through the connector 5. The guide member extends in the front-to-back direction and guides the movement of the driver, preventing the driver's motion trajectory from deviating, thereby preventing the movable baffle 2 from deviating and ensuring the stability of the movable baffle 2.

[0037] In the smoke machine of the present invention, Figure 6 As shown, the driving member 41 adopts a reduction motor, which is arranged on the upper surface of the top plate 11. The transmission member includes a transmission gear 42 and a rack 43. The transmission gear 42 is connected to the output end of the reduction motor, and the rack 43 is engaged with the transmission gear 42. The guide member includes a slide 44, which is arranged on the upper surface of the top plate 11. The rack 43 is slidably connected to the slide 44, and the connecting member 5 is connected to the rack 43.

[0038] 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 movable baffle 2 can be controlled. The transmission gear 42 cooperates with the rack 43 to convert the rotation of the output end of the reduction motor into the linear motion of the rack 43, so that the rack 43 drives the movable baffle 2 to move linearly through the connecting member 5. For example, when the output end of the reduction motor rotates forward, it can drive the movable baffle 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 movable baffle 2 to move forward to close the air suction port 111. The slide 44 extends in the front-to-back direction. The slide 44 can guide the linear movement process of the rack 43 to prevent the movement trajectory of the rack 43 from deviating.

[0039] In the smoke machine of the present invention, Figure 6 As shown, the guide member further includes a slide bar 45, which is slidably connected to the slide seat 44, the rack 43 is connected to the slide bar 45, and the connecting member 5 is provided at the rear end of the slide bar 45. The slide bar 45 and the slide seat 44 are slidably engaged, which can increase the engagement area between the guide member and the slide seat 44, thereby improving the engagement stability between the guide member and the slide seat 44, thereby improving the stability of the guiding process of the movable baffle 2.

[0040] 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.
