It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0054] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0056] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0057] The present embodiment provides a range hood head, which can be applied to an integrated stove to achieve smoke collection during the fume extraction process, improve the smoke collection effect, enhance the fume extraction capacity of the integrated stove, and at the same time improve the safety of use of the range hood head and the integrated stove.

[0058] like Figure 1 and Figure 2As shown, the cigarette machine head includes a machine head body, a flap assembly 2 and a flap driving mechanism 3. Specifically, the machine head body has a connected smoke collecting cavity 16 and a smoking port, and the smoking port is arranged on the front side of the machine head body. The flap assembly 2 has a closed state in which the smoking port is closed and an open state in which the smoking port is opened; the flap driving mechanism 3 drives the flap assembly 2 to switch between the open state and the closed state.

[0059] The machine head body includes a machine head frame 1 and a smoke guide plate assembly 6. The machine head frame 1 has a smoke collecting chamber 16 with an open front side. The smoke guide plate assembly 6 is detachably arranged on the front side of the machine head frame 1 and closes the lower opening of the smoke collecting chamber 16. A smoking port is formed between the top of the machine head frame 1 and the upper end of the smoke guide plate assembly 6. When the flap assembly 2 is in a closed state, the front side surface of the flap assembly 2 is flush with the front side surface of the smoke guide plate assembly 6, that is, the flap assembly 2 and the smoke guide plate assembly 6 are spliced ​​up and down, so that the overall appearance of the smoke machine head is simple and easy to clean.

[0060] When the flap assembly 2 is in the open state, the flap assembly 2 extends forward from top to bottom, so that the machine head frame 1, the smoke guide plate assembly 6 and the flap assembly 2 form a C-shaped negative pressure zone, whose open radiation surface can envelop the oil smoke area and block the upper body of the cook, forming high and low negative pressure zones, wherein the high negative pressure zone is formed near the upper end of the smoke guide plate assembly 6, and the low negative pressure zone is formed at the C-shaped negative pressure zone formed by the machine head frame 1, the smoke guide plate assembly 6 and the flap assembly 2. When the oil smoke rises to the high negative pressure zone, most of the oil smoke can be instantly sucked into the smoke collection chamber 16 from above the smoke guide plate assembly 6, and a small part of the oil smoke enters the C-shaped negative pressure zone due to the large rising force. At this time, the oil smoke transitions to the inside of the smoke collection chamber 16 along the flap assembly 2, the top wall of the smoke collection chamber 16, and the rear wall of the smoke collection chamber 16, thereby improving the smoke collection effect of the range hood head and the integrated stove.

[0061] It is worth noting that the directional descriptions such as "front", "back", "left" and "right" in the previous and following texts are based on the position of the range hood head relative to the operator when it is in use, that is, the side of a structure close to the operator is the front side, the side away from the operator is the back side or dorsal side, the side close to the left hand of the operator facing the range hood head is the left side, and the side close to the right hand of the operator facing the range hood head is the right side.

[0062] In this embodiment, when the flap assembly 2 is in the open state, the angle of the flap assembly 2 relative to the vertical plane is 50° to 70°, so as to increase the range of the oil smoke envelope, improve the smoothness of the oil smoke passing through the C-shaped negative pressure area into the smoke collecting chamber 16, and improve the smoke collecting effect. When the flap assembly 2 is in the open state, the distance between the lower end of the flap assembly 2 and the plane where the outer side of the smoke guide plate assembly 6 is located is 240mm to 300mm, which can effectively block the noise generated by a part of the smoking port while meeting the smoking effect, so as to reduce the noise transmitted to the human ear, thereby reducing the noise during cooking and improving the user experience.

[0063] In order to improve the installation stability of the flap drive mechanism 3 on the head frame 1, the head frame 1 also includes a reinforcing beam 15, which is installed on the front side of the back plate 12, and the flap drive mechanism 3 is installed on the reinforcing beam 15. Therefore, the overall structural strength and rigidity of the head frame 1 are improved by the setting of the reinforcing beam 15, and the supporting performance of the head frame 1 for the flap drive mechanism 3 is improved, and the probability of deformation at the connection between the head frame 1 and the flap drive mechanism 3 is reduced, thereby reducing the probability of vibration of the flap drive mechanism 3 and the head frame 1 during use, and reducing the noise of the range hood head and the integrated stove.

[0064] The flap driving mechanism 3 is preferably arranged in the middle of the head frame 1 in the left-right direction, thereby improving the force balance of the flap assembly 2, thereby improving the operational reliability of the flap assembly 2. The reinforcing beam 15 preferably extends in the vertical direction, and the lower end of the reinforcing beam 15 preferably extends to the shell bottom plate, and the upper end of the reinforcing beam 15 preferably extends to the top beam 11, so as to further enhance the structural strength and rigidity of the head frame 1.

[0065] In order to improve the performance of the flap driving mechanism 3, an oil-proof cover 5 is provided on the outer cover of the flap driving mechanism 3 to provide oil-proof protection for the flap driving mechanism 3. The specific structures of the flap driving mechanism 3, the oil-proof cover 6 and the flap assembly 2 and the specific mounting structure on the machine head frame 1 can be set with reference to the prior art, which is not the focus of the present utility model and will not be described in detail here.

[0066] In this embodiment, in order to improve the smoke-collecting effect of the cigarette machine head, the left and right ends of the flap assembly 2 are connected to the side baffle assemblies 4, and the side baffle assembly 4 includes a mounting shaft 42 installed on the top of the head body and at least two side smoke baffles 41 that are rotatably sleeved on the mounting shaft 42 in turn. The two adjacent side smoke baffles 41 on the same side can be relatively unfolded, so that the side baffle assembly 4 can be unfolded and block the lateral gap between the flap assembly 2 and the head body when the flap assembly 2 is flipped to open the smoking port. The two adjacent side smoke baffles 41 can be relatively closed, so that the side baffle assembly 4 can be folded and hidden in the back side of the flap assembly 2 when the flap assembly 2 is flipped to close the smoking port.

[0067] By providing a side baffle assembly 4 that can be expanded and folded with the flap assembly 2, when the flap assembly 2 is opened, the side baffle assembly 4 can be expanded to close the lateral gap between the flap assembly 2 and the head body, thereby reducing the probability of oil smoke escaping to the left and right sides, improving the smoking effect, and thus enhancing the smoke collecting effect of the range hood head; at the same time, the side baffle assembly 4 can be folded with the closing of the flap assembly 2, so that the expanded area of ​​the side baffle assembly 4 when the flap assembly 2 is opened can meet the lateral smoke blocking effect while reducing the space occupied by the side baffle assembly 4 after the flap assembly 2 is closed, so that when the flap assembly 2 is in a closed state, the side baffle assembly 4 can be completely accommodated in the smoke collecting chamber 16, and the thickness requirement of the range hood head is reduced, thereby improving the structural compactness of the range hood head; the expansion and closing of the side baffle assembly 4 is realized by the relative expansion and closing of a plurality of side smoke baffles 41, which is easy to realize and can improve the convenience of connection between the side baffle assembly 4 and the flap assembly 2 and the head body.

[0068] For the convenience of description, the state when the flap assembly 2 is flipped to the maximum opening angle is called the open state, and the side baffle assembly 4 is in the unfolded state; the state when the flap assembly 2 closes the smoking port is called the closed state, and the side baffle assembly 4 is in the folded state.

[0069] In order to simplify the structure of the hood, in this embodiment, the left and right ends of the flap assembly 2 are rotatably connected to the hood body through the side baffle assembly 4, that is, the flap assembly 2 does not need to adopt other structures to achieve its installation on the hood body, while ensuring the stability and smoothness of the flip assembly 2, the parts of the hood are reduced and the structure of the hood is simplified. In other embodiments, the flap assembly 2 can also be installed on the hood frame 1 using other rotatable installation structures, such as the two ends and / or the middle of the flap assembly 2 are rotatably connected to the top of the hood frame 1 using rockers.

[0070] The head frame 1 includes a back plate 12, a top beam 11 connected to the top of the back plate 12, two columns 13 connected to the left and right sides of the back plate 12, and a bottom beam 14 connected to the lower end of the back plate 12, and the left and right ends of the bottom beam 14 are respectively connected to the two columns 13. The back plate 12, the top beam 11, the bottom beam 14 and the two columns 13 enclose a smoke chamber 16. The lower end of the smoke guide plate assembly 6 is connected to the bottom beam 14, and the left and right sides of the smoke guide plate assembly 6 are installed on the front side of the two columns 13. The left and right sides of the smoke guide plate assembly 6 are preferably aligned with the left and right outer sides of the two columns 13 to improve the appearance of the head frame 1 and the smoke machine head. A smoke exhaust port 141 is provided on the bottom surface of the bottom beam 14, and the smoke exhaust port 141 is connected to the smoke chamber 16 to discharge the oil smoke into the air duct inside the integrated stove.

[0071] In this embodiment, the top beam 11 includes a round beam portion 112, which extends in the left-right direction and has two ends extending to the upper parts of the two columns 13. The setting of the round beam portion 112 makes the top of the head frame 1 present an arc surface structure, making the entire range hood head smooth and simple in appearance and aesthetically pleasing; at the same time, the rear end running track of the flap assembly 2 is an arc shape, and the setting of the round beam portion 112 is conducive to providing avoidance for the rear end of the flap assembly 2, improving the coordination between the top beam 11 and the flap assembly 2, avoiding the flap assembly 2 from scratching the top beam 11 when flipping, and reducing the gap between the rear end of the flap assembly 2 and the top beam 11 when the flap assembly 2 is opened, thereby reducing the probability of oil smoke escaping upward from the gap between the two, and improving the smoke collection effect of the range hood head.

[0072] The top beam 11 also includes a top plate 111, the rear end of the round beam 112 is connected to the back plate 12, the front end of the round beam 112 is connected to the top plate 111, the top plate 111 extends obliquely backward from top to bottom, and the top plate 111 is located between the two columns 13. The round beam 112, the top plate 111 and the back plate 12 together form a top space, and the top space extends in the left and right direction. The inclined top plate 111 is conducive to guiding the oil smoke flowing to the top beam 11 to flow downward, improving the drainage effect of the oil smoke flow, and thus improving the smoke collection effect of the range hood head.

[0073] In other embodiments, the side baffle assembly 4 may also adopt a flexible structure, so that when the flap assembly 2 is flipped open, the side baffle assembly 4 flexibly unfolds to increase the shielding area, and when the flap assembly 2 is flipped closed, the side baffle assembly 4 flexibly folds by deformation to reduce the unfolded area of ​​the side baffle assembly 4.

[0074] In order to improve the overall aesthetics and simplicity of the range hood head, the rotating shaft 42 is installed inside the top beam 11, and the side baffle assembly 4 extends outward from the top beam 11, so that the connection structure between the side baffle assembly 4 and the head frame 1 can be hidden inside the top beam 11 to avoid being exposed, so that the overall structure of the range hood head is relatively simple; at the same time, it can also reduce the pollution of the connection structure between the side baffle assembly 4 and the head frame 1 caused by oil smoke, which is beneficial to ensure the smooth rotation and operational reliability of the side baffle assembly 4, and reduce the probability of adhesion between two adjacent side smoke baffles 41 or between the side smoke baffles 41 and other structures.

[0075] In order to improve the convenience of disassembly and assembly of the side baffle assembly 4, the left and right ends of the top plate 111 are spaced from the two columns 13, so that a rotation gap is formed between the two ends of the top plate 111 and the two columns 13, and the two side baffle assemblies 4 are respectively arranged at the rotation gap. This arrangement allows the width of the two rotation gaps to be controlled by setting the length of the top plate 111 during the processing of the top beam 11, thereby reserving a gap for the installation of the side baffle assembly 4, and there is no need to additionally open a hole or groove structure on the top beam 11 for the side baffle assembly 4 to rotate through, thereby simplifying the processing of the top beam 11 and the head frame 1, reducing the difficulty of assembling and disassembling the side baffle assembly 4, and improving the assembly efficiency of the smoke machine head. ,

[0076] Furthermore, the left and right sides of the top plate 111 are folded forward to form side flaps 113, and the side baffle assembly 4 is located between the side flaps 113 and the adjacent columns 13. The side flaps 113 can enhance the overall structural strength and rigidity of the top beam 11, while preventing the edges of the top plate 111 at both ends from scratching the side baffle assembly 4, and can also stop the oil smoke from flowing into the top beam 11.

[0077] In order to improve the installation and rotation stability of the flap assembly 2 and the side baffle assembly 4, a reinforcing block 17 is provided inside the top beam 11. The reinforcing blocks 17 are provided one-to-one with the side baffle assemblies 4, and the two side baffle assemblies 4 are respectively installed on the two reinforcing blocks 17. By providing the reinforcing blocks 17 and installing the side baffle assemblies 4 on the reinforcing blocks 17, the support performance of the head frame 1 for the flap assembly 2 and the side baffle assembly 4 can be enhanced, and the probability of deformation at the connection between the head frame 1 and the side baffle assembly 4 can be reduced, thereby improving the flip reliability of the flap assembly 2 and the side baffle assembly 4 and improving the service life of the smoke machine head.

[0078] like Figure 3 and Figure 4 As shown, in this embodiment, the installation shaft 42 includes a screw portion, an optical axis portion and a limit portion which are sequentially connected along the axial direction, and the outer diameters of the screw portion, the optical axis portion and the limit portion are sequentially increased. Among them, the screw portion is screwed on the reinforcing block 17 to achieve the fixation of the installation shaft 42 relative to the reinforcing block 17; the optical axis portion is located on the outer side of the reinforcing block 17 and the end face abuts against the reinforcing block 17, all the side smoke baffles 41 are sleeved on the optical axis portion, and the side baffles are clamped between the end face of the reinforcing block 17 and the limit portion to prevent the side smoke baffles 41 from moving along the axial direction of the installation shaft 42, thereby improving the installation and operation reliability of the side baffle assembly 4.

[0079] In order to reduce the friction between the reinforcing block 17 and the side smoke baffle 41, a boss portion 171 is partially protruded inwardly on one side of the reinforcing block 17 facing the side smoke baffle 41, and the boss portion 171 protrudes from the column 13 in the left-right direction, and the screw portion of the mounting shaft 42 is mounted on the boss portion 171, and the end surface of the boss portion 171 abuts against the outermost side smoke baffle 41. In this way, the contact area between the reinforcing block 17 and the side smoke baffle 41 can be reduced, and at the same time, the interference between the side smoke baffle 41 and the column 13 can be avoided, ensuring that the side smoke baffle 41 can be spaced apart from the column 13.

[0080] Preferably, the boss portion 171 is a truncated cone structure, and the small end of the boss portion 171 faces the side smoke baffle plate 41, thereby ensuring the structural strength and rigidity of the boss portion 171 and the protruding height of the boss portion 171 while further reducing the contact area between the boss portion 171 and the side smoke baffle plate 41.

[0081] In order to reduce the friction when the two side smoke baffles 41 rotate relative to each other, the side baffle assembly 4 also includes a separator 44, which is sleeved on the mounting shaft 42, and a separator 44 is provided between two adjacent side smoke baffles 41, and the opposite sides of the separator 44 are respectively in contact with the two side smoke baffles 41. By providing the separator 44, the two side smoke baffles 41 are arranged at intervals, so that when the side baffle assembly 4 is unfolded or closed, the two side smoke baffles 41 will not contact each other, effectively reducing the noise caused by the friction between the side smoke baffles 41, improving the smoothness of the unfolding and closing of the side baffle assembly 4, and improving the user experience of the hood head.

[0082] The separator 44 is an annular structure, and the outer diameter of the separator 44 is 20mm~50mm, and the axial thickness of the separator 44 along the mounting shaft 42 is 2mm~5mm, so as to ensure that the spacing between two adjacent side smoke baffles 41 will not change significantly, avoiding the problem of the upper ends of the two adjacent side smoke baffles 41 being separated and the lower ends contacting each other.

[0083] In this embodiment, each side baffle assembly 4 includes two side smoke baffles 41, and the side smoke baffle 41 connected to the flap assembly 2 is an active baffle 41a, and the other side smoke baffle 41 is a follower baffle 41b. By providing two side smoke baffles 41, the structure of the side baffle assembly 4 can be simplified, and the difficulty of processing and assembling the side baffle assembly 4 can be reduced. In other embodiments, each side baffle assembly 4 can also be provided with three or more side smoke baffles 41.

[0084] like Figures 5 to 9As shown, in order to better realize the deployment of the side baffle assembly 4, a toggle component 43 is provided between two adjacent side smoke baffles 41, and the toggle component 43 is used to toggle the adjacent side smoke baffle 41 to rotate during the rotation of one side smoke baffle 41, so that all the side smoke baffles 41 are deployed in sequence when the flap assembly 2 is rotated and opened. By providing the toggle component 43, it can be ensured that when the smoke baffle 41 on one side is rotated and deployed, the smoke baffle 41 on the other side can be driven to be deployed accordingly, thereby ensuring the smoothness and reliability of the deployment of the side baffle assembly 4, and further ensuring the operational reliability of the flap assembly 2.

[0085] In this embodiment, the shifting component 43 includes a rear shifting component 43a protruding from the active baffle 41a. When the flap assembly 2 is in a closed state, the rear shifting component 43a is spaced apart at the rear side of the follower baffle 41b.

[0086] Since the active baffle 41a is connected to the flap assembly 2, when the flap assembly 2 rotates and unfolds under the driving action of the flap driving mechanism 3, the active baffle 41a rotates with the flap assembly 2. Since when the flap assembly 2 is closed, the rear shifting component 43a is spaced apart from the rear side of the follower baffle 41b, that is, when the active baffle 41a rotates to a certain angle, the rear shifting component 43a abuts against the rear side of the follower baffle 41b, thereby making the active baffle 41a rotate synchronously with the rotation of the flap assembly 2 and shifting the follower baffle 41b to rotate forward, so that the follower baffle 41b can rotate out of the front side of the machine head frame 1.

[0087] In other embodiments, other structures can also be used to achieve the follow-up setting between adjacent side smoke baffles 41. For example, one of the two adjacent side baffle assemblies 4 is provided with a slide groove, and the other is provided with a toggle protrusion. The slide groove is an arc groove, and the center of the circle corresponding to the arc groove is located on the rotation axis of the mounting shaft 42; when one side of the smoke baffle 41 rotates forward, the toggle protrusion slides in the slide groove, and when the toggle protrusion slides to abut against the groove wall at one end of the slide groove, it drives the adjacent side baffles to rotate synchronously; or, two adjacent side smoke baffles 41 are connected by a flexible wire, and when the side baffle assembly 4 is in a folded state, the flexible wire is bent, and when one side of the smoke baffle 41 rotates, the flexible wire connected to it is gradually straightened, and when the flexible wire is pulled until it is tensioned, the connected side smoke baffle 41 is pulled to rotate and unfold accordingly.

[0088] It is understandable that when there are multiple side smoke baffles 41, except for the side smoke baffle 41 farthest from the active baffle 41a, all other side smoke baffles 41 are provided with a toggle component 43. For example, when there are three side smoke baffles 41, the three side smoke baffles 41 are respectively the active baffle 41a, the first follower baffle and the second follower baffle, and the first follower baffle is located between the active baffle 41a and the second follower baffle. At this time, the active baffle 41a and the first follower baffle are both provided with a toggle component 43. When the active baffle 41a rotates a certain angle with the flap assembly 2, the toggle component 43 on the active baffle 41a toggle the first follower baffle to rotate forward; when the first follower baffle rotates a certain angle, the toggle component 43 on the first follower baffle toggle the second follower baffle to rotate, so that each side smoke baffle 41 is deployed in sequence.

[0089] The toggle component 43 also includes a front toggle component 43b protruding from the active baffle 41a, the follower baffle 41b is partially located between the front toggle component 43b and the rear toggle component 43a, and the follower baffle 41b is spaced apart from at least one toggle component 43, and the front toggle component 43b can push the follower baffle 41b to rotate backward when the flap assembly 2 is flipped closed.

[0090] The setting of the front shifting component 43b enables the active baffle 41a to rotate backward with the flap assembly 2 when the flap assembly 2 rotates from the open state to the closed state, and the follower baffle 41b slowly moves backward under the action of its own gravity; when the active baffle 41a moves to the point where the front shifting component 43b contacts the follower baffle 41b, the front shifting component 43b pushes the follower baffle 41b backward, so that the follower baffle 41b and the active baffle 41a rotate backward synchronously until the flap assembly 2 returns to the closed state, and at the same time, the side baffle assembly 4 returns to the folded state. That is, the setting of the front shifting component 43b can ensure that the follower baffle 41b can be effectively pushed back to the position when the flap assembly 2 is in the folded state, ensuring the efficiency of the side baffle assembly 4 when switching from the unfolded state to the closed state, and also preventing the flap assembly 2 from colliding with the follower baffle 41b when flipping backward to close, thereby ensuring the safety and reliability of the flap assembly 2.

[0091] In other embodiments, the front shifting component 43b may not be provided, that is, when the side baffle assembly 4 switches from the unfolded state to the folded state, the follower baffle 41b can be reset to the position in the folded state under the action of gravity or the backward push of the flap assembly 2.

[0092] That is, the side baffle assembly 4 provided in the present embodiment can reduce the size of a single baffle while ensuring that the side baffle assembly 4 can be expanded to a larger area, thereby increasing the smoke collecting area, by driving the active baffle 41a to move with the movement of the flap assembly 2 so as to ensure that the side baffle assembly 4 can be expanded to a larger area, thereby increasing the smoke collecting area; at the same time, by providing a toggle component 43 to achieve the relative expansion or closing of two adjacent baffles, the reliability of the expansion and closing of the two adjacent baffles can be improved, and there is no need to provide an additional driving structure, thereby reducing costs; furthermore, the provision of such side baffle assembly 4 enables each side baffle to be individually processed and replaced as required, thereby improving the processing convenience of the side baffle assembly 4 and reducing the processing cost of the side baffle assembly 4; furthermore, compared with a solution that requires two baffles to slide together to achieve expansion or folding, the provision of such side baffle assembly 4 can reduce the area required for the follower baffle 41b, and there is no need to provide a guiding groove on the follower baffle 41b and the active baffle 41a, thereby reducing the probability of oil smoke leaking from the guiding groove.

[0093] Furthermore, when the follower baffle 41b contacts the front shifting member 43b, the follower baffle 41b is spaced apart from the flap assembly 2. This can prevent the follower baffle 41b from contacting the flap assembly 2, thereby preventing the follower baffle 41b from colliding with the flap assembly 2 during the flipping process of the flap assembly 2, thereby preventing the flap assembly 2 from breaking and causing a loud collision noise, thereby improving the safety of the flap assembly 2 and the safety and reliability of the hood head.

[0094] Suppose the center line of the installation shaft 42 and the surface of the front shifting component 43b is the first plane, and the center line of the installation shaft 42 and the surface of the rear shifting component 43a is the second plane. The angle between the first plane and the second plane is preferably 30° to 150°, and more preferably 30° to 70°.

[0095] Preferably, the front toggle member 43b and the rear toggle member 43a are preferably cylindrical rod-shaped structures to reduce the scratches on the follower baffle 41b. The two toggle members 43 are preferably welded to the active baffle 41a to ensure the stability of the arrangement of the toggle members 43. In other embodiments, the two toggle members 43 can be integrally formed with the active baffle 41a, or the two toggle members 43 can be inserted on the active baffle 41a by interference.

[0096] The active baffle 41a includes a main baffle portion 41a2 and an active rocker arm portion 41a1 connected to the rear side of the upper end of the main baffle portion 41a2, the upper end of the active rocker arm portion 41a1 is rotatably sleeved on the mounting shaft 42, and the front side of the main baffle portion 41a2 is connected to the flap assembly 2. By providing the main baffle portion 41a2 and the active rocker arm portion 41a1, the front side edge of the main baffle portion 41a2 can be located outside the top beam 11, while the active rocker arm portion 41a1 can penetrate into the top beam 11 to connect with the mounting shaft 42, thereby reducing the structural interference between the active baffle 41a and the top beam 11, and improving the installation convenience of the side baffle assembly 4.

[0097] An escape notch 41a3 with a front opening is formed between the active rocker arm portion 41a1 and the main baffle portion 41a2, and the front end of the round beam portion 112 is inserted into the escape notch 41a3, so that when the rear end of the flap assembly 2 can be flipped to the front of the round beam portion 112, the active baffle 41a will not interfere with the top beam 11. Specifically, the active rocker arm portion 41a1 includes a first arm portion and a second arm portion connected at an angle, an end of the first arm portion away from the second arm portion is sleeved on the mounting shaft 42, and an end of the second arm portion away from the first arm portion is connected to the rear side of the upper end of the main baffle portion 41a2, and the first arm portion, the second arm portion and the main baffle portion 41a2 together form an escape notch 41a3 with a front opening.

[0098] The follower baffle 41b includes a follower rocker arm portion 41b1 and an auxiliary baffle portion 41b2. The upper end of the follower rocker arm portion 41b1 is rotatably mounted on the mounting shaft 42 and the lower end is connected to the upper end of the auxiliary baffle portion 41b2. The width of the follower rocker arm portion 41b1 gradually increases in a direction away from the auxiliary baffle portion 41b2, and the width of the auxiliary baffle portion 41b2 gradually increases in a direction away from the follower rocker arm portion 41b1. The shifting component 43 abuts against the lower end of the follower rocker arm portion 41b1.

[0099] This arrangement can increase the width of the lower edge of the follower baffle 41b while reducing the width of the follower baffle 41b between the two toggle components 43, thereby reducing the spacing between the two toggle components 43, and further reducing the width of the upper end of the active baffle 41a, thereby reducing the size of the upper end of the entire side baffle assembly 4, improving the structural compactness of the side baffle assembly 4, and reducing the size requirement of the side baffle assembly 4 for the top space; furthermore, with this arrangement, the two toggle components 43 can be set as far away from the mounting shaft 42 as possible, thereby reducing the probability of the active rocker arm portion 41a1 and the follower rocker arm portion 41b1 being deformed by force under long-term operation, thereby increasing the service life of the side baffle assembly 4, and improving the reliability of the side baffle assembly 4 and the flap assembly 2.

[0100] The follower swing arm portion 41b1 and the auxiliary baffle portion 41b2 are connected at an angle, and the angle between the follower swing arm portion 41b1 and the auxiliary baffle portion 41b2 is set forward. This arrangement makes it unnecessary for the follower baffle 41b to be set vertically when the side baffle assembly 4 is in the folded state, thereby improving the flexibility of the setting position of the two toggle components 43.

[0101] When the side guard assembly 4 is in the folded state, the follower rocker arm portion 41b1 is tilted backward from top to bottom, the rear shifting component 43a is spaced apart on the upper side of the follower rocker arm portion 41b1, and the rear shifting component 43a and the front shifting component 43b are spaced apart in the vertical direction. This arrangement can reduce the width of the front shifting component 43b and the rear shifting component 43a in the front-to-back direction while the angle between the first plane and the second plane meets the requirements, thereby reducing the size requirements for the top space and reducing the probability of structural interference.

[0102] When the side baffle assembly 4 is in the folded state, the front side of the auxiliary baffle portion 41b2 extends forward from top to bottom, so as to increase the length of the lower edge of the following baffle 41b as much as possible while avoiding the collision between the following baffle 41b and the flap assembly 2, thereby increasing the effective smoke-collecting area of ​​the following baffle 41b when it is unfolded. Further, the rear side of the auxiliary baffle portion 41b2 extends backward from top to bottom and is spaced from the back plate 12, so as to reduce the distance between the rear side of the lower end of the following baffle 41b and the back plate 12 while avoiding the collision between the following baffle 41b and the back plate 12, thereby increasing the length of the lower edge of the following baffle 41b, and ensuring that when the side baffle is in the unfolded state, the rear edge of the following baffle 41b can be located on the inner side of the column 13, thereby ensuring the lateral smoke-collecting effect of the side baffle assembly 4.

[0103] In this embodiment, the lower edge of each side smoke baffle 41 is an arc-shaped edge. When the flap assembly 2 is in the open state, the arc-shaped edges of two adjacent side smoke baffles 41 are tangently arranged on a projection plane perpendicular to the left and right directions. This arrangement can reduce the probability of interference between the rear end of the side baffle assembly 4 and the back plate 12 when increasing the total length of the lower end of the side smoke baffle assembly 41, thereby ensuring that the side baffle assembly 4 will not interfere with the head frame 1, while increasing the area of ​​the side baffle assembly 4 when it is unfolded, thereby improving the smoke collection effect of the smoke machine head; at the same time, the arrangement of the arc-shaped edge enables the side baffle assembly 4 to form a fan-shaped structure when unfolded, and the appearance is more beautiful. In other embodiments, the lower edge of each side smoke baffle 41 can also be a straight line structure or a broken line structure.

[0104] Preferably, when the side baffle assembly 4 is in the unfolded state, the rear side of the main baffle portion 41a2 is parallel to the front side of the main baffle portion 41a2 and is spaced apart, and the rear edge of the main baffle portion 41a2 is located behind the front edge of the auxiliary baffle portion 41b2. This arrangement enables the rear side of the main baffle portion 41a2 and the front side of the auxiliary baffle portion 41b2 to partially overlap in the left and right directions when the side baffle assembly 4 is in the unfolded state, thereby reducing the probability of oil smoke flowing out of the gap between the two and improving the smoke collection effect; furthermore, while ensuring that the rear sides of the main baffle portion 41a2 and the auxiliary baffle portion 41b2 partially overlap, the overlapping area of ​​the two in the folded state is reduced, thereby reducing the area requirement for the follower baffle 41b.

[0105] like Figures 6 to 10 As shown, in the present embodiment, in order to prevent the follower baffle 41b from being manually pushed forward when the side baffle assembly 4 is in the expanded state, in the present embodiment, a front stop component 18 is provided on the machine head body, and the front stop component 18 is separately provided from the active baffle 41a. When the flap assembly 2 is in the open state, the front side of the follower baffle 41b abuts against the front stop component 18, and the rear side of the follower baffle 41b abuts against the rear push component 43a.

[0106] By setting the front stop component 18, when the side baffle assembly 4 is in the expanded state, the follower baffle 41b is clamped between the rear shift component 43a and the front stop component 18, ensuring that the follower baffle 41b is stable, thereby ensuring the stability of the side baffle assembly 4 in the expanded state; at the same time, this setting can also effectively prevent the follower baffle 41b from flipping forward and colliding with the flap assembly 2, effectively avoiding the problem of the flap assembly 2 being broken or the follower baffle 41b being deformed due to collision with the flap assembly 2, thereby improving the safety and long-term reliability of the range hood head. Specifically, the front stop component 18 can abut against the front side of the lower end of the follower rocker arm portion 41b1; furthermore, the setting of the front stop component 18 makes it possible that when the follower baffle 41b and the active baffle 41a are adhered to each other and cause the flap assembly 2 to flip open, when the follower baffle 41b and the active baffle 41a rotate forward synchronously, the front stop component 18 can abut against the front side of the follower baffle 41b to limit the follower baffle 41b from continuing to flip forward, so that the active baffle 41a and the follower baffle 41b can be separated again, ensuring that the side baffle assembly 4 can smoothly switch to the expanded state, ensuring the expansion effect of the side baffle assembly 4.

[0107] In order to prevent the follower baffle 41b from continuing to flip backwards and colliding with the back plate 12 after flipping backwards to the reset position, the machine head body is provided with a rear stopper 19, which can abut against the rear side of the follower baffle 41b when the follower baffle 41b returns to the initial position to limit the follower baffle 41b from continuing to rotate backwards. That is, when the flap assembly 2 is in the closed state, the rear side of the follower baffle 41b abuts against the rear stopper 19.

[0108] The setting of the rear stop component 19 enables the follower baffle 41b to be reliably maintained in the initial position, preventing the follower baffle 41b from continuing to flip backward and causing a bump on the back plate 12 or the top beam 11, thereby improving the reliability of the side baffle assembly 4; at the same time, the setting of the rear stop component 19 enables, when the active baffle 41a and the follower baffle 41b are adhered, causing the active baffle 41a and the follower baffle 41b to rotate backward synchronously, the rear stop component 19 can be abutted against the follower baffle 41b to limit the follower baffle 41b from continuing to rotate backward, and the active baffle 41a can continue to rotate backward, thereby realizing the separation of the active baffle 41a and the follower baffle 41b, ensuring that the side baffle assembly 4 can smoothly return to the folded state.

[0109] In the present embodiment, the front stop component 18 and the rear stop component 19 are both arranged on the reinforcement block 17, and the follower baffle 41b is arranged between the active baffle 41a and the reinforcement block 17, so that the front stop component 18 and the rear stop component 19 can protrude from the column 13 in the left and right directions to act on the follower rocker arm portion 41b1, thereby improving the convenience of setting the front stop component 18 and the rear stop component 19, and avoiding interference between the front stop component 18 and the rear stop component 19 and the active baffle 41a; at the same time, since the overall structural rigidity of the reinforcement block 17 is relatively large, the front stop component 18 and the rear stop component 19 are arranged on the reinforcement block 17, which can reduce the probability of deformation at the connection between the front stop component 18 and the rear stop component 19 and the reinforcement block 17, thereby improving the reliability of the range hood head.

[0110] To simplify the structure, the front stopper 18 and / or the rear stopper 19 are rod-shaped structures, so that the front stopper 18 and the rear stopper 19 have simple structures and are easy to process. In other embodiments, the front stopper 18 and / or the rear stopper 19 may also be block-shaped structures.

[0111] Furthermore, the front stopper 18 passes through the pillar 13 forward to improve the flexibility of the setting position of the front stopper 18, and the rear stopper 19 is set above the pillar 13. In another embodiment, the front stopper 18 and / or the rear stopper 19 can also be directly set on the pillar 13. In another embodiment, the front stopper 18 and the rear stopper 19 can be convexly set on the side flap portion 113, and the follower baffle 41b is set between the active baffle 41a and the side flap portion 113.

[0112] This embodiment also provides an integrated stove, comprising the above-mentioned hood head. The integrated stove provided by the utility model can improve the oil fume extraction effect of the integrated stove and improve the use performance of the integrated stove by adopting the above-mentioned hood head.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
