[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0030] References to "embodiments" or "implementations" herein mean that a particular feature, structure, or characteristic described in conjunction with the embodiments or implementations may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] 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.

[0032] In order to inhale the aerosol containing oil smoke, the range hood needs to be equipped with an air suction port. The air suction ports of common range hoods are usually open by default. Regardless of whether the range hood is in the on or dormant state, the flue connected to the air suction port is always directly connected to the indoor room. Since some of the oil smoke in the aerosol will inevitably remain in the flue, the always open air suction port may cause this part of the oil smoke to return to the room again, such as dripping from the air suction port. For example, when the range hood is dormant and the outdoor air pressure is greater than the indoor air pressure, an airflow from the outdoor to the indoor may be formed in the flue. This airflow will carry the oil smoke in the flue back to the indoor room, affecting the indoor cleanliness and hindering the normal operation of the range hood.

[0033] 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.

[0034] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 1 This is a schematic structural diagram of an embodiment of an air intake device 1 provided by the present invention. Figure 2 This is a schematic structural diagram of another embodiment of the air intake device 1 provided by the present invention. Figure 3 This is a schematic structural diagram of the air suction device 1 provided by the present invention with the first air suction port 17 and the second air suction port 18 closed. Figure 4 A schematic diagram of the structure of the air suction device 1 provided by the present invention with the first air suction port 17 and the second air suction port 18 opened. The embodiment of the present application provides an air suction device 1 for sucking aerosol in a space and discharging the aerosol to a specified position. The air suction device 1 may include a device body 11 and a movable panel 12.

[0035] A first air inlet 17 and a second air inlet 18 are formed between the device body 11 and the movable panel 12. The device body 11 and the movable panel 12 are movably connected in the vertical direction, so that they can move relative to each other to synchronously open or close the first air inlet 17 and the second air inlet 18. The first air inlet 17 is oriented downward in the vertical direction, and the second air inlet 18 is oriented perpendicular to the vertical direction.

[0036] In the structure provided in this embodiment, by providing the device body 11 and the movable panel 12 that are movably connected in the vertical direction, a first air inlet 17 and a second air inlet 18 with different directions are formed between the two, so that the first air inlet 17 and the second air inlet 18 can be opened and closed synchronously by utilizing the relative movement of the device body 11 and the movable panel 12, so as to achieve the purpose of controllable opening and closing of the first air inlet 17 and the second air inlet 18, and improve the usability of the air inhalation device 1. When the first air inlet 17 and the second air inlet 18 are open, the air inhalation device 1 can use the first air inlet 17 and the second air inlet 18 to inhale aerosols from different directions and positions, thereby expanding the effective range of the air inhalation device 1 and improving the working efficiency of the air inhalation device 1.

[0037] See also Figure 5 , Figure 6 , Figure 7 , Figure 5 This is a schematic diagram of the exploded structure of the air intake device 1 provided by the present invention. Figure 6 This is a schematic cross-sectional structural diagram of the air intake device 1 provided by the present invention with the first air intake port 17 and the second air intake port 18 opened. Figure 7 A schematic cross-sectional structure diagram of the air suction device 1 provided by the present invention with the first air suction port 17 and the second air suction port 18 closed. In one embodiment of the present application, the movable panel 12 may include a first sleeve portion 121, and the device body 11 may include a second sleeve portion 111, and the first sleeve portion 121 and the second sleeve portion 111 are movably sleeved. When the movable panel 12 and the device body 11 move relative to each other until they abut, the first sleeve portion 121 and the second sleeve portion 111 are completely sleeved, and at this time, the first air suction port 17 and the second air suction port 18 are closed.

[0038] In the structure provided in this embodiment, the first air inlet 17 and the second air inlet 18 can be formed between the first sleeve part 121 and the second sleeve part 111. When the movable panel 12 abuts against the device body 11, the sleeve connection between the first sleeve part 121 and the second sleeve part 111 can be utilized to save space while closing the first air inlet 17 and the second air inlet 18 in different directions at the same time, thereby achieving the purpose of improving the usability of the air suction device 1. And due to the abutment relationship between the movable panel 12 and the device body 11, the relative position of the two can be limited, thereby improving the structural stability of the air suction device 1.

[0039] In one embodiment of the present application, the second sleeve portion 111 can be specifically movably sleeved outside the first sleeve portion 121, and the second air suction port 18 is formed on the outer wall of the first sleeve portion 121 facing the second sleeve portion 111. The movable panel 12 also includes a lower panel 122, which is arranged on the lower side of the first sleeve portion 121, and the lower panel 122 extends parallel to the lower surface of the second sleeve portion 111 in a direction away from the first sleeve portion 121. When the first air suction port 17 and the second air suction port 18 are closed, the lower panel 122 can abut against the lower surface of the second sleeve portion 111.

[0040] In the structure provided in this embodiment, when the first sleeve portion 121 and the second sleeve portion 111 are fully sleeved, the second sleeve portion 111 can cover the second air intake port 18 on the outer wall of the first sleeve portion 121, and the lower panel 122 can further abut against the lower surface of the second sleeve portion 111, thereby achieving the closure of the second air intake port 18 and limiting the relative position of the first sleeve portion 121 and the second sleeve portion 111, which can improve the availability and structural stability of the air intake device 1.

[0041] In an embodiment of the present application, the device body 11 may further include a third sleeve portion 112, the third sleeve portion 112 is sleeved and fixed with the second sleeve portion 111, and the first air inlet 17 is formed on the lower surface of the first sleeve portion 121. When the lower panel 122 abuts against the lower surface of the second sleeve portion 111, the third sleeve portion 112 is sleeved in the first air inlet 17 of the first sleeve portion 121, and the lower side surface of the third sleeve portion 112 is parallel to the lower panel 122. The lower side surface of the third sleeve portion 112 can at least partially block the first air inlet 17 on the lower surface of the first sleeve portion 121, thereby achieving the effect of closing the first air inlet 17.

[0042] The structure provided in this embodiment relatively fixes the second sleeve part 111 and the third sleeve part 112 through the sleeve relationship among the first sleeve part 121, the second sleeve part 111 and the third sleeve part 112. When the first air suction port 17 and the second air suction port 18 are closed, the first sleeve part 121 has two opposite side surfaces facing the second sleeve part 111 and the third sleeve part 112 respectively, so that the second sleeve part 111 and the third sleeve part 112 can be used to close the second air suction port 18 and the first air suction port 17 respectively. The structure is simple and reliable, and can effectively save installation space, thereby improving the availability of the air suction device 1.

[0043] In an embodiment of the present application, the air inhalation device 1 may further include a signal receiving component 15 and a control component 16, wherein the control component 16 connects the signal receiving component 15 and the movable panel 12. When the signal receiving component 15 sends a control message to the control component 16, the control component 16 analyzes the control message and generates a corresponding control signal, thereby controlling the movable panel 12 to move relative to the device body 11.

[0044] For example, the signal receiving component 15 may include a human-computer interaction interface, and the user inputs a specified command to the signal receiving component 15 through the human-computer interaction interface. For example, the user issues a "power on" command through the human-computer interaction interface, and the control component 16 generates a corresponding control signal, thereby controlling the movable panel 12 to move vertically downward relative to the device body 11, and opening the first air suction port 17 and the second air suction port 18. Using the structure provided in this embodiment, the signal receiving component 15 can send a corresponding control message to the control component 16 in response to the specified command, so that the control component 16 can generate a corresponding control signal to control the device body 11, which can improve the availability of the air suction device 1.

[0045] See also Fig. 9 , Fig. 9 The structure schematic diagram of the air suction device 1 provided by the present invention. In one embodiment of the present application, the air suction device 1 may specifically include a movable part 13 and a motor 14, wherein the movable part 13 is connected to the movable panel 12, the device body 11 and the output end of the motor 14, and the motor 14 is connected to the control component 16. Among them, when the motor 14 outputs to the movable part 13 according to the control signal, the movable part 13 respectively connected to the device body 11 and the movable panel 12 can move under the drive of the motor 14, thereby driving the movable panel 12 to move relative to the device body 11, and realizing the opening and closing control of the first air suction port 17 and the second air suction port 18.

[0046] See also Figure 8 , Figure 8 The schematic diagram of the structure of the transmitter 151a and the receiver 151b provided by the present invention. In one embodiment of the present application, the signal receiving component 15 may specifically include a sensor component 151. The sensor component 151 is at least partially arranged on the side surface of the movable panel 12 away from the device body 11. For the hidden air inhalation device 1, most of the device body 11 is installed in the wall and / or cabinet, and usually only the movable panel 12 that needs to inhale the aerosol and is arranged toward the cooking area, and the adjacent part of the device body 11 are exposed, so as to achieve an installation effect that is beautiful and easy to clean.

[0047] Therefore, the sensor component 151 is arranged on the side surface of the movable panel 12 away from the device body 11, which can meet the installation requirements of the hidden range hood. At the same time, the side surface will move with the movement of the movable panel 12, and the sensor component 151 can obtain the current state of the air inhalation device 1 through the movement of the movable panel 12. Figure 3 , Figure 4In the air suction device 1 shown, the movable panel 12 is provided with a sensor component 151 on one side thereof facing the cooking area, so that the second air suction port 18 can be arranged corresponding to the user's body and / or face, so that the aerosol escaping from the cooking area to the vicinity of the user is sucked in by the second air suction port 18, thereby reducing the phenomenon of oil smoke blowing in the face and reducing the adverse effects of oil smoke on the user. The user can easily give commands to the sensor component 151, for example, the user extends his hand between the cooking area and the movable panel 12 to make a gesture, thereby giving commands to the air suction device 1 such as turning on, turning off, adjusting the working power, etc.

[0048] In one embodiment of the present application, the sensor component 151 may include a transmitter 151a and a receiver 151b, wherein the transmitter 151a is used to send a detection instruction at a first time interval, and the receiver 151b is used to receive the detection instruction. The transmitter 151a and the receiver 151b are arranged adjacent to and / or opposite to each other, and the control message includes the time difference from the transmitter 151a sending the detection instruction to the receiver 151b receiving the detection instruction, so that the control component 16 can judge the current state of the suction device 1 and the user command by analyzing the time difference in the control message, and then control the motor 14 to drive the movable part 13 to perform the corresponding operation, so as to achieve the purpose of effectively controlling the suction device 1.

[0049] The transmitter 151a and the receiver 151b may be disposed on a surface of the air intake device 1 facing the cooking area, or on a tabletop 2 in the cooking area that is stationary relative to the device body 11 .

[0050] like Fig. 9 As shown, the dotted line with an arrow indicates the signal transmission direction F. When the transmitter 151a and the receiver 151b are arranged opposite to each other, when the user's hand blocks the light path between the two, the detection instruction sent by the transmitter 151a is blocked by the hand, so that the receiver 151b cannot receive the detection instruction, thereby effectively controlling the time difference and achieving the effect of inputting commands to the suction device 1 according to user needs.

[0051] When the transmitter 151a and the receiver 151b are arranged adjacent to each other, when the user does not extend his hand, the detection instruction sent by the transmitter 151a is reflected from the cooking area to the receiver 151b with a stable time difference. When the user extends his hand, the position of the hand is closer to the air suction device 1 than the cooking area, so that the time for the detection instruction to be reflected to the receiver 151b is shortened, thereby effectively controlling the time difference and achieving the effect of inputting commands to the air suction device 1 according to user needs.

[0052] In one embodiment of the present application, the signal receiving component 15 may include a camera and a visual sensor. The camera is disposed on the outer surface of the air suction device 1 and is adjacent to the first air suction port 17 and / or the second air suction port 18. The camera is oriented in the same direction as the adjacent first air suction port 17 and / or the second air suction port 18. The camera is connected to the visual sensor, and the visual sensor is connected to the control component 16. The visual sensor is used to identify the image sent by the camera and generate a corresponding control message, so that the control function of the air suction device 1 can be realized through the camera and the visual sensor, thereby improving the usability of the air suction device 1.

[0053] For example, the user can make a gesture to the camera, and the visual sensor recognizes the user's gesture, thereby controlling the air suction device 1 accordingly. For another example, when the camera is arranged adjacent to the second air suction port 18, its direction is toward the user together with the second air suction port 18. When the user does not enter the camera area of ​​the camera, that is, when the cooking area is unused, the air suction device 1 can naturally be in a dormant state. When the user enters the camera area of ​​the camera, that is, when the user is likely to use the cooking area, the visual sensor can send a control message in response to the user's portrait appearing in the image, so that the control component 16 controls the air suction device 1 to start.

[0054] In one embodiment of the present application, the signal receiving component 15 may include a sound receiving component, which is at least partially disposed on the outer surface of the air suction device 1, so as to receive control messages in the form of voice. After a period of use, the outer surface of the air suction device 1 will inevitably accumulate fumes and stains. If it is necessary to control the air suction device 1 by touching buttons, the user will inevitably come into contact with these oil stains, which affects hygiene and brings a bad user experience. The structure provided in this embodiment can avoid setting buttons on the air suction device 1, so that the user can input commands to the air suction device 1 in the form of voice, thereby improving the usability of the air suction device 1.

[0055] Mentioning "embodiment" and "implementation method" in the present invention means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present invention.
