[0057] like Figure 1 and Figure 2 As shown, the cigarette machine head comprises a machine head frame 1, a smoke guide plate assembly 6 and a flap mechanism. The machine head frame 1 has a smoke collecting chamber 16 with an open front side, the smoke guide plate assembly 6 is installed on the front side of the machine head frame 1 and closes the lower opening of the smoke collecting chamber 16, and a smoking port is formed between the top of the smoke guide plate assembly 6 and the top of the machine head frame 1; the flap mechanism comprises a flip panel 2 and a flip drive mechanism 3, the flip drive mechanism 3 is installed on the machine head frame 1 and can drive the flip panel 2 to switch between an open state of opening the smoking port and a closed state of closing the smoking port.

[0058] When the range hood head is not in use, the flip panel 2 is in a closed state, the flip panel 2 closes the smoking port, and the front side of the flip panel 2 is flush with the front side of the smoke guide plate assembly 6 to prevent the odor inside the range hood head from escaping out through the smoking port, and make the overall appearance of the range hood head simple and beautiful, so as to improve the appearance and cleaning convenience of the range hood head and the integrated stove; when the range hood head is in use, the flip plate driving mechanism 3 drives the flip panel 2 to flip open the smoking port, so that the oil smoke can enter the smoke collection chamber 16 through the smoking port, and the flip panel 2 can stop the oil smoke from escaping upward, thereby enhancing the smoke collection effect.

[0059] like Figure 2 and Figure 3 As shown, the head frame 1 includes a back plate 12, a top beam 11 connected to the top of the back plate 12, two side frames 13 connected to the left and right sides of the back plate 12, and a bottom frame assembly 14 connected to the lower end of the back plate 12, and the left and right ends of the bottom frame assembly 14 are respectively connected to the two side frames 13. The back plate 12, the top beam 11, the bottom frame assembly 14 and the two side frames 13 are surrounded to form a smoke collecting chamber 16. The lower end of the smoke guide plate assembly 6 is docked with the bottom frame assembly 14, and the left and right sides of the smoke guide plate assembly 6 are installed on the front side of the two side frames 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 side frames 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 frame assembly 14, and the smoke exhaust port 141 is connected to the smoke collecting chamber 16 to discharge the oil smoke into the air duct inside the integrated stove.

[0060] like Figure 3 and Figure 4 As shown, in the present embodiment, the top beam 11 has a round beam portion 112 extending in the left-right direction, a rear connecting portion 113 connected to the rear end of the round beam portion 112, and a front connecting portion 114 connected to the front end of the round beam portion 112. The rear connecting portion 113 is fastened to the top end of the back plate 12 through a rear fastener, and the front connecting portion 114 is fastened to the front side of the back plate 12 through a front fastener. A plurality of rear fasteners and front fasteners are arranged at intervals in the left-right direction.

[0061] The head frame 1 provided in the present embodiment has a circular beam portion 112, so that the head frame 1 and the top of the hood are in an arc structure, so that the entire hood is smooth and simple in appearance and has a strong aesthetic appearance; at the same time, the setting of the circular beam portion 112 is conducive to providing avoidance for the rear end of the flip panel 2, improving the coordination between the top beam 11 and the flip panel 2, reducing the probability of interference between the flip panel 2 and the head frame 1 during the flipping process, and can reduce the gap between the rear end of the flip panel 2 and the top beam 11 when the flip panel 2 is in the open state, thereby reducing The probability of smoke leakage is reduced, and the smoke collection effect of the range hood head is improved; furthermore, by arranging a plurality of rear fasteners and a plurality of front fasteners at intervals along the left and right directions, the stability of the connection between the rear end of the top beam 11 and the back plate 12 and the tightness of the connection between the front end of the top beam 11 and the back plate 12 can be ensured, so that the front and rear ends of the top beam 11 are both reliably fixed, thereby ensuring the consistency of the overall arc surface of the round beam portion 112 in the left and right directions, avoiding the round beam portion 112 from partially protruding outward and causing scratches against the wall or the flip panel 2, thereby improving the flipping smoothness of the flip panel 2.

[0062] It is worth noting that the directional descriptions such as "front", "rear", "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 certain structure close to the operator is the front side, the side away from the operator is the rear 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.

[0063] In this embodiment, the top beam 11 also includes a top plate portion 111, which is connected between the front end of the round beam portion 112 and the front connecting portion 114, and the top plate portion 111 extends obliquely backward from top to bottom. The round beam portion 112, the top plate portion 111 and the back plate 12 together form a top space, and the top space extends in the left-right direction. Since the top plate portion 111 extends obliquely downward from front to back, the lower side of the top plate portion 111 is inclined to the front and downward, which is conducive to the installation of the lighting lamp 7, the temperature sensing module or other electrical components on the top plate portion 111, and improves the convenience of installing the electrical components on the head frame 1; the inclined top plate portion 111 is also conducive to guiding the oil smoke flowing to the top beam 11 to flow downward, improving the drainage effect of the oil smoke flow, thereby improving the smoke collection effect of the range hood head.

[0064] Preferably, the circular beam portion 112 and the top plate portion 111 are integrally formed, so that the structural strength and rigidity of the top beam 11 are better, thereby improving the overall structural strength and rigidity of the head frame 1, and can simplify the assembly between the top beam 11 and other structures of the head frame 1, improve the assembly efficiency of the head frame 1, and thus improve the assembly efficiency of the smoke exhaust machine head; furthermore, since the circular beam portion 112 and the top plate portion 111 are integrally formed, during assembly, the inclination angle of the top plate portion 111 relative to the horizontal plane can be adjusted according to the use requirements of the smoke exhaust machine head to ensure that the orientation of the electrical components can better meet the lighting or detection requirements, thereby improving the use reliability and design flexibility of the head frame 1 and the smoke exhaust machine head, and while adjusting the inclination angle of the top plate portion 111, it can be ensured that the top plate portion 111 and the circular beam portion 112 are always tangent to each other, thereby ensuring the smoothness and aesthetics of the appearance of the top beam 11.

[0065] Furthermore, the top beam 11 is integrally formed to reduce the processing difficulty of the top beam 11 and improve the overall structure and rigidity of the top beam 11. In other embodiments, the round beam portion 112 and the top plate portion 111 may also be welded or detachably connected.

[0066] In this embodiment, the inclination angle of the top plate portion 111 relative to the horizontal plane is 30° to 60°, which is conducive to guiding the oil smoke that flows upward along the inner side of the flip panel 2 to the top beam 11 to flow downward to the inside of the smoke collection chamber 16, thereby improving the oil smoke drainage effect, thereby improving the smoke collection effect and oil fume exhaust effect of the range hood head.

[0067] When the flip panel 2 is in the open state, the flip panel 2 extends forward from top to bottom, so that the head frame 1, the smoke guide plate assembly 6 and the flip panel 2 form a C-shaped negative pressure zone, and its 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 head frame 1, the smoke guide plate assembly 6 and the flip panel 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 flip panel 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.

[0068] like Figures 4 to 6 As shown, in order to improve the connection convenience and connection stability between the top beam 11 and the back plate 12, the rear end of the round beam 112 is connected with a rear connection part 113, and the rear connection part 113 is connected to the top of the back plate 12 through a rear fastener, and a plurality of rear fasteners are arranged at intervals along the left and right directions. By arranging the rear connection part 113, the arc-shaped structure of the round beam 112 will not restrict the connection between the top beam 11 and the back plate 12, thereby improving the connection convenience between the top beam 11 and the back plate 12; by arranging a plurality of rear fasteners at intervals along the left and right directions, the connection stability between the rear end of the top beam 11 and the back plate 12 can be ensured, thereby ensuring the consistency of the arc surface of the rear side of the round beam in the left and right directions, avoiding the rear side of the round beam from partially protruding outwards and scratching against the wall or other structures, and improving the safety of the range hood head.

[0069] The rear end of the top plate 111 is connected to a front connection part 114, and the front connection part 114 is connected to the back plate 12 via a front fastener, and a plurality of front fasteners are arranged at intervals along the left-right direction. The front connection part 114 and the plurality of front fasteners can ensure the stability of the connection between the front side of the top plate 111 and the back plate 12, thereby ensuring the consistency of the front arc surface of the round beam 112 in the left-right direction, avoiding the front arc surface of the round beam 112 partially protruding forward and causing scratches with the flip panel 2, ensuring the smoothness of the flip panel 2 flipping, and improving the reliability of the range hood head.

[0070] That is, in this embodiment, the top beam 11 is connected to the top beam 11 through the rear connecting part 113 and the front connecting part 114, so that the front and rear sides of the top beam 11 are reinforced and fixed to the back plate 12, ensuring the consistency of the curvature of the steam curved surface of the circular beam part 112, and effectively avoiding the problem that the circular beam part 112 has a large curvature in the middle and a small curvature at both ends, and effectively preventing the flip panel 2 from hitting the top beam 11 when flipping, thereby improving the smoothness of the appearance of the top beam 11 and the structural aesthetics of the head frame 1 and the smoke machine head.

[0071] In order to improve the connection convenience between the rear connecting part 113 and the back panel 12, the rear connecting part 113 includes a vertically arranged rear vertical plate part 1131, and the back panel 12 includes a back panel body 121. The top end of the back panel body 121 is folded to form a fixed flange part 122. The fixed flange part 122 is relatively arranged on the front side of the rear vertical plate part 1131, and the rear fastener connects the rear vertical plate part 1131 and the fixed flange part 122. By setting a vertical rear vertical plate portion 1131, the rear vertical plate portion 1131 is set parallel to the back plate main body 121, and the round beam portion 112 and the rear vertical plate portion 1131 can be tangent, avoiding obvious protrusions or depressions at the connection between the top beam 11 and the back plate 12, thereby improving the overall smoothness of the head frame 1 and the smoke machine head; by setting the rear vertical plate portion 1131 and the fixed flange portion 122 relatively arranged at the front and rear, the rear fastener can be passed from back to front, thereby improving the convenience of the rear fastener connecting the top beam 11 and the back plate 12.

[0072] The back plate body 121 and the rear vertical plate portion 1131 are preferably arranged flush with each other to ensure that the shape of the head frame 1 and the rear side of the range hood are flat, thereby reducing the probability of the head frame 1 and the range hood hood colliding with the wall.

[0073] Furthermore, the rear connection portion 113 further includes a lower folding portion 1132 vertically connected to the front side of the lower end of the rear vertical plate portion 1131, an upper folding portion 123 is connected between the fixed flange portion 122 and the back plate body 121, and the lower folding portion 1132 is attached to the upper side of the upper folding portion 123 and abuts against the rear side surface of the fixed flange portion 122. The arrangement of the lower folding portion 1132 and the upper folding portion 123 facilitates the assembly and positioning of the top beam 11 and the back plate 12, and ensures the assembly accuracy of the top beam 11 and the back plate 12.

[0074] In other embodiments, the rear connecting portion 113 may also only include the lower folding portion 1132, the back panel 12 includes a back panel body 121 and an upper folding portion 123 folded forward from the upper end of the back panel body 121, and the rear fastener is passed through the lower folding portion 1132 and the upper folding portion 123 to fasten the back panel 12 and the top beam 11.

[0075] In order to improve the installation stability of the rear fastener, the rear vertical plate portion 1131 is provided with a fastening boss protruding forward, and the fixed flange portion 122 is provided with a rear stud portion 186 protruding forward.

The rear fastener is inserted into the countersunk hole and the threaded hole, and the screw head of the rear fastener is sunken in the countersunk hole to prevent the rear fastener from protruding backward from the rear vertical plate portion 1131 and to ensure the matching length of the rear fastener with the top beam 11 and the back plate 12.

[0076] The front connection portion 114 is formed by folding the lower end of the top plate portion 111 upward, and the front connection portion 114 is in contact with the front side of the back plate 12, and the front fastener is hidden in the rear side of the top plate portion 111. By folding the top plate portion 111 upward to form the front connection portion 114, the processing of the front connection portion 114 can be simplified, thereby simplifying the overall structure of the top beam 11 and reducing the processing difficulty of the top beam 11.

[0077] In order to improve the connection stability between the front connection part 114 and the back plate 12, the front connection part 114 is formed with a front cone part by back-to-front stamping, and the front end surface of the front cone part is convexly provided with a front stud part 186, and an escape cavity is formed inside the front cone part; the back plate body 121 is convexly provided with a rear cone part, which is inserted into the escape cavity and the front end is in contact with the front side cavity wall of the escape cavity, and the rear cone part is surrounded by a countersunk hole, and the front stud part 186 is provided with a threaded hole, and the front stud part 186, the front cone part and the rear cone part are all arranged in a one-to-one correspondence with the front fastener. The front fastener is sequentially inserted into the countersunk hole and the threaded hole, and the screw head of the front threaded part is sunken into the countersunk hole.

[0078] Furthermore, the front fasteners and the rear fasteners are staggered in the left-right direction, thereby reducing stress concentration at the back plate 12 and further improving the connection reliability between the top beam 11 and the back plate 12 .

[0079] In order to improve the overall structural strength of the top beam 11, both the left and right sides of the top plate 111 are folded forward to form side flanges 115, thereby enhancing the overall structural strength of the top beam 11 and reducing the probability of deformation of the top plate 111. The left and right ends of the front connecting portion 114 are preferably in contact with the side flanges 115, and the rear side of the side flanges 115 is preferably in contact with the back plate 12, so that the side flanges 115 block part of the lateral gap between the top plate 111 and the back plate 12, reducing the probability of oil smoke entering the top space through the lateral gap. In other embodiments, the side flanges 115 can also be welded to the left and right ends of the front connecting portion 114.

[0080] Furthermore, both ends of the top of the back plate 12 are connected with a shaping piece 17, and the shaping piece 17 has a circular arc shaping surface. The circular arc shaping surfaces of the two shaping pieces 17 are coaxially arranged, and the shaping piece 17 is located inside the circular beam portion 112, and the inner side surface of the circular beam portion 112 is in contact with the circular arc shaping surface. By arranging a shaping piece 17 at each of the left and right ends of the circular beam portion 112, it is possible to better ensure that the curvature of the curved surface at both ends of the circular beam portion 112 is consistent, which is conducive to ensuring the consistency of the curvature of the entire circular beam portion 112 in the left and right directions, avoiding the problem of scratching the flip panel 2 due to the large local curvature of the circular beam portion 112, and improving the operating reliability of the flip panel 2.

[0081] In order to ensure the installation reliability of the shaping member 17, the lower end of the shaping member 17 is detachably connected to the back plate 12 and / or the side frame 13, so as to facilitate the processing, setting and replacement of the shaping member 17, and the diameter of the round beam portion 112 can be set and adjusted by setting and adjusting the arc shaping surface of the shaping member 17, thereby improving the design flexibility of the head frame 1 and the smoke machine head. The shaping member 17 can adopt an annular structure, in which case the inner ring or the outer side of the shaping member 17 can be provided with a sealing plate structure to close the two end openings of the top space, or the shaping member 17 can also adopt a plate structure, that is, the shaping member 17 directly closes the two end openings of the top space.

[0082] like Figure 2 and Figure 4 As shown, in the present embodiment, in order to improve the installation of the flip panel 2, rotating components 5 are provided at both ends of the flip panel 2, and the rotating components 5 are rotatably installed inside the top beam 11, thereby ensuring that the connection position between the rotating component 5 and the head frame 1 is hidden in the top space, thereby improving the overall simplicity and aesthetics of the range hood head, and reducing the damage of oil smoke to the connection between the rotating component 5 and the head frame 1, thereby ensuring the smoothness of the rotation of the rotating component 5 relative to the head frame 1.

[0083] In order to improve the installation convenience and the smoothness of the rotation of the rotating assembly 5, in this embodiment, the left and right ends of the top plate 111 are spaced from the two side frames 13, so that a rotation gap is formed between the two ends of the top plate 111 and the two side frames 13, and the two rotating assemblies 5 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 rotating assembly 5, and there is no need to additionally open a hole or groove structure on the top beam 11 for the rotating assembly 5 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 rotating assembly 5, and improving the assembly efficiency of the smoke machine head.

[0084] like Figure 2 and Figure 5 As shown, in order to improve the installation and rotation stability of the flip panel 2 and the rotating assembly 5, a reinforcing block 18 is provided inside the top beam 11. The reinforcing blocks 18 are provided one-to-one with the rotating assembly 5, and the two rotating assemblies 5 are respectively installed on the two reinforcing blocks 18. By providing the reinforcing blocks 18 and installing the rotating assembly 5 on the reinforcing blocks 18, the support performance of the head frame 1 for the flip panel 2 can be enhanced, and the probability of deformation at the connection between the head frame 1 and the flange can be reduced, thereby improving the flip reliability of the flip panel 2 and increasing the service life of the smoke machine head.

[0085] like Figure 5 , Figure 7 and Figure 8As shown, the reinforcing block 18 is detachably connected to the side frame 13 and the back plate 12, respectively, to ensure the installation stability of the reinforcing block 18. Specifically, the lower end of the reinforcing block 18 is inserted into the side frame 13 and connected to the side frame 13, and the upper end of the reinforcing block 18 extends out of the side frame 13 and into the top space, thereby ensuring that the upper end of the reinforcing block 18 is located in the top space, improving the connection convenience between the reinforcing block 18 and the side frame 13, and ensuring the installation stability of the reinforcing block 18 at the side frame 13.

[0086] It is worth noting that the structure of the rotating component 5 can be set with reference to the prior art, and the structure of the rotating component 5 that can realize the rotatable installation of the flip panel 2 on the head frame 1 can be applied to this embodiment. This embodiment does not limit or elaborate on the structure of the rotating component 5.

[0087] like Figure 3 and Figure 8 As shown, in order to improve the performance of the range hood head, a mounting hole 1112 is provided on the top plate 111, and a lighting lamp 7 is installed in the mounting hole 1112, so that when the cooking environment is dark, the stove can be illuminated by the lighting lamp 7, thereby improving the cooking experience. At the same time, the top plate 111 is tilted backward from top to bottom, which is also conducive to the light emitted by the lighting lamp 7 being set directly on the stove, ensuring the suitability of the lighting range of the lighting lamp 7 and improving the use experience of the range hood head. Preferably, two mounting holes 1112 are preferably arranged at intervals in the left and right directions, so that the two lighting lamps 7 can be respectively set directly on the two burners of the gas stove to better meet the lighting needs.

[0088] In other embodiments, a temperature sensing module or a visual detection device or other detection components may also be provided on the top plate, wherein the temperature sensing module is used to detect the cooking temperature of the stove and above it downward, so as to realize the wind force adjustment during the fume extraction through the detection of the cooking temperature, and improve the user experience of the hood head; the visual detection device can be used to take pictures of the cooking status, cooking ingredients, cooking utensils, etc. for the controller to identify, so as to realize the intelligent control of the operation of the integrated stove. Two detection components may be provided in the left and right directions, so that the two detection components can detect the two burners of the gas stove respectively; or only one detection component may be provided in the middle of the left and right directions, and the detection field of the detection component covers the two burners of the gas stove.

[0089] In this embodiment, the flip plate driving mechanism 3 is installed on the head frame 1 and is located in the middle of the head frame 1 in the left-right direction to improve the force stability of the flip panel 2 during the flipping process. The flip plate driving mechanism 3 is installed between the two lighting lamps 7 to avoid interference between the flip plate driving mechanism 3 and the lighting lamps 7. In other embodiments, the flip plate driving mechanism 3 can also be installed inside the top space of the top beam 11. In this case, two lighting lamps 7 or detection components can be arranged at intervals in the left-right direction, or one can be arranged in the middle of the top plate 111.

[0090] It is understandable that only one of the illuminating lamp 7 and the detecting member can be provided, and if the installation space permits, the illuminating lamp 7 and the detecting member can be provided at the same time. Alternatively, the illuminating lamp 7 and the detecting member can also be integrated and provided at the same position.

[0091] The flap driving mechanism 3 includes a linear driving member 31 and a driving rod 32. The lower end of the linear driving member 31 is hinged to the machine head frame 1. The lower end of the driving rod 32 is connected to the telescopic part 311 of the linear driving member 31. The upper end of the driving rod 32 is connected to the upper part of the flip panel 2, so that the linear driving member 31 drives the flap assembly 2 to switch between the open state and the closed state through the driving rod 32. In order to protect the linear driving member 31, in this embodiment, the hood head also includes an oil-proof cover 4. The oil-proof cover 4 is installed in the smoke chamber 16 and is surrounded by the back plate 12 and the top plate 111 to form an oil-proof chamber. The linear driving member 31 is arranged in the oil-proof chamber, and the driving rod 32 passes through the oil-proof chamber.

[0092] The specific structure of the flap driving mechanism 3 and the oil shield 4 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.

[0093] A wire threading hole 1113 is provided on the top plate portion 111, and the connecting wire of the linear drive member 31 enters the top space of the top beam 11 through the wire threading hole 1113, and the connecting wire extends horizontally to a side frame 13, and then extends downward along the internal space of the side frame 13 to pass through the range hood head, so as to realize the connection between the connecting wire and the controller inside the integrated stove.

[0094] The top plate 111 is recessed from front to back to form a top groove 1111, which is located in the oil-proof cavity. The top groove 1111 is formed by stamping the top plate 111 backward to form a top pressing profile 1114 at the rear side of the top plate 111, thereby increasing the structural strength and rigidity of the top plate 111, thereby increasing the structural strength and rigidity of the top beam 11, and the top groove 1111 is shielded by the oil-proof cover 4 to avoid exposure of the top groove 1111, thereby improving the overall structural aesthetics and cleaning convenience of the range hood head. The threading hole 1113 is set at the bottom of the top groove 1111.

[0095] like Figure 7 and Figure 8As shown, a reinforcing beam 15 is installed on the front side of the back plate 12, the oil-proof cover 4 is installed on the front side of the reinforcing beam 15 and encloses the reinforcing beam 15 to form an oil-proof cavity, the lower end of the oil-proof cover 4 is detachably connected to the reinforcing beam 15, and the lower end of the linear drive member 31 is installed on the reinforcing beam 15 through a drive mounting seat. The provision of the reinforcing beam 15 can enhance the structural strength of the connection between the head frame 1 and the linear drive member 31, reduce the probability of deformation of the head frame 1, improve the overall structural strength and rigidity of the head frame 1, and ensure the installation stability of the flap drive mechanism 3 on the head frame 1.

[0096] The reinforcing beam 15 includes a beam main plate portion 151 which is parallel to and spaced from the back plate 12 and two beam side plates 152 connected to the left and right sides of the beam main plate portion 151. The rear edge of the beam side plate portion 152 is folded inward to form a beam folding portion 153. The beam folding portion 153 is in contact with the back plate 12 and is detachably connected, thereby achieving the fastening between the reinforcing beam 15 and the back plate 12, and making the connection structure between the reinforcing beam 15 and the back plate 12 hidden in the rear side of the beam main plate portion 151 and not exposed, thereby improving the structural aesthetics and cleaning convenience of the head frame 1. The reinforcing beam 15 and the back plate 12 are preferably connected by fastening screws to improve the connection stability.

[0097] Furthermore, the front side of the beam main plate 151 is recessed backward to form a mounting groove 1511, and a drive mounting seat is arranged in the mounting groove 1511, and the lower end of the linear drive member 31 is rotatably mounted on the drive mounting seat through the lower hinge shaft. By recessing the mounting groove 1511 from front to back, the back of the beam main plate 151 can form a profiled structure at the same time, so as to enhance the overall structural strength and rigidity of the beam main plate 151 and reduce the probability of deformation of the beam main plate 151; at the same time, the drive mounting seat is arranged in the mounting groove 1511, and the lower end of the linear drive member 31 is installed on the drive mounting seat, so that the mounting groove 1511 can avoid part of the structure of the flap drive mechanism 3, thereby improving the overall structural compactness of the smoke machine head, so that the linear drive member 31 can be arranged further away from the smoke guide plate assembly 6, so that the oil protection cover 4 can be further away from the smoke guide plate assembly 6.

[0098] In this embodiment, the reinforcing beam 15 extends in the vertical direction, the lower end of the reinforcing beam 15 extends to abut against the bottom frame assembly 14, and the upper end of the reinforcing beam 15 extends to the top beam 11, thereby increasing the length of the reinforcing beam 15, thereby enhancing the structural strength of the entire head frame 1. In other embodiments, the reinforcing beam 15 can also extend in the left-right direction, and the two ends of the reinforcing beam 15 are respectively connected to the two side frames 13.

[0099] A plug hole 1141 is provided in the middle of the front connecting part 114 along the length direction. The upper end of the reinforcing beam 15 passes through the plug hole 1141 and extends into the top space of the top beam 11. The shape of the plug hole 1141 is consistent with the cross-sectional shape of the reinforcing beam 15 to achieve the installation and positioning of the reinforcing beam 15 and the top beam 11. The upper edge of the plug hole 1141 is folded outward to form a hole flap portion 116. The hole flap portion 116 is fitted and connected to the front side of the reinforcing beam 15 to ensure the installation stability of the reinforcing beam 15. The hole flap portion 116 is located inside the oil cover 4. This arrangement makes the connection between the reinforcing beam 15, the back plate 12 and the top beam 11 more tightly, ensures the structural rigidity of the entire head frame 1, and reduces the probability of deformation of the head frame 1.

[0100] Preferably, the spacing between the main beam portion 151 and the back plate 12 is 5 mm to 12 mm, so as to avoid the overall structural rigidity of the reinforcing beam 15 being reduced due to the spacing being too large, and to avoid the smoke chamber 16 occupying too much space due to the spacing being too large.

[0101] Note that the above are only preferred embodiments of the present invention and the technical principles used. 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.
