[0040] This utility model provides a range hood. See also... Figure 1 and Figure 2 , Figure 1 This is a structural diagram of the range hood in standby mode, provided in an embodiment of the present invention. Figure 2 This is a structural diagram showing the upper and lower panels of the range hood in the open state according to an embodiment of the present invention. The range hood 100 provided by the present invention includes a housing 10 and a smoke collection chamber 20. An air inlet is provided at the front of the smoke collection chamber 20, and an upper panel 30 and a lower panel 40 are provided at the air inlet. (See also...) Figure 3 , Figure 4 ,as well as Figure 5 , Figure 3 This is a structural diagram of the range hood with the lower panel open, as provided in an embodiment of the present invention. Figure 4 for Figure 3 A magnified schematic diagram of the structure at point A in the middle. Figure 5 This is a partially enlarged structural diagram of the range hood with its lower panel open, as provided in this embodiment of the present invention. The range hood 100 also includes at least one set of connecting mechanisms, comprising: a damping rotation mechanism 50 and a connecting seat 60. The damping rotation mechanism 50 is provided with a rotating arm 51 and a fixed seat 52 fixedly connected to the smoke collection chamber 20. The base plate 61 of the connecting seat 60 is fixed to the lower plate 40, and a protrusion 62 is provided on its upper surface. (See also...) Figure 6 , Figure 6This is a schematic diagram of the connecting seat in the range hood provided in this embodiment of the utility model. One end of the protrusion 62 is provided with an insertion hole 621 that is adapted to the free end of the rotating arm 51. After the free end of the rotating arm 51 is inserted into the insertion hole 621, the connecting seat 60 and the rotating arm 51 are engaged and fixed by the engaging mechanism 70.

[0041] In this embodiment, the range hood 100, when the free end of the rotating arm 51 of the damping rotation mechanism 50 is inserted into the socket 621, and the connecting seat 60 and the rotating arm 51 are engaged and fixed by the engaging mechanism 70, when an inward pushing force is applied to the lower panel 40, the rotating arm 51 in the damping rotation mechanism 50 will receive an inward pushing force from the lower panel 40, thereby causing the lower panel 40 to rotate inward, thus closing the lower panel 40. When an outward pulling force is applied to the lower panel 40, the rotating arm 51 in the damping rotation mechanism 50 will receive an outward pulling force from the lower panel 40, thereby causing the lower panel 40 to rotate outward, thus opening the lower panel 40, at which point the interior of the lower panel 40 can be cleaned. After opening the lower panel 40, open the engaging mechanism 70 that locks the connecting seat 60 and the rotating arm 51. Then, apply an upward and outward pulling force to the lower panel 40 to disengage the free end of the rotating arm 51 of the damping rotating mechanism 50 from the insertion hole 621 in the connecting seat 60, thereby disassembling the lower panel 40. At this time, the lower panel 40 and the smoke collection chamber 20 can be thoroughly cleaned, which greatly facilitates the user in cleaning the range hood 100.

[0042] In some embodiments, see Figure 5 , Figure 6 ,as well as Figure 7 , Figure 7 This is a schematic diagram of the assembly structure of the damping rotation mechanism of a range hood according to another embodiment of the present invention. The engaging mechanism 70 includes: a limiting part 71 disposed at the connecting end of the rotating arm 51, and an engaging ring 72 disposed on the protrusion 62 and engaging with the limiting part 71. See also Figure 5The engaging ring 72 is a U-shaped engaging ring, with its opening engaged on both sides of the protrusion 62. It is rotatably fixed to the protrusion 62 via the rotating shaft 73. After the free end of the rotating arm 51 is inserted into the insertion hole 621, the protrusion 62 and the rotating arm 51 on the connecting seat 60 are fixed by engaging the bottom of the U-shaped engaging ring 72 with the limiting part 71. The range hood 100 provided by this utility model, after the free end of the rotating arm 51 of the damping rotating mechanism 50 is inserted into the socket 621, applies a pushing force toward the limiting part 71 to the bottom of the U-shaped locking ring 72. After contacting the limiting part 71, the bottom of the U-shaped locking ring 72 will undergo a certain degree of elastic deformation under the action of the pushing force. After reaching the matching locking position with the limiting part 71, the bottom of the U-shaped locking ring 72 will rely on its own tendency to restore its original shape and tightly hug the limiting part 71, thereby achieving locking and fixing with the limiting part 71.

[0043] In some embodiments, see Figure 2 and Figure 3 The connecting mechanism consists of two sets; the two damping rotation mechanisms 50 in the two sets of connecting mechanisms are respectively fixed to both sides of the bottom of the smoke collection chamber 20 by fixing seats 52; the two connecting seats 60 in the two sets of connecting mechanisms are respectively fixed to both sides of the bottom of the inner wall of the lower panel 40 by the base plate 61. This arrangement ensures that the lower panel 40 will not shake and can be stably and detachably fixed to the smoke collection chamber 20.

[0044] In some embodiments, see Figure 6 and Figure 7 The damping rotation mechanism 50 is assembled from a nut 53, a rotating arm 51, a washer 54, a fixed base 52, and a fixing pin 55. The washer 54 is used to reduce friction, provide cushioning, and adjust the clearance. See also... Figure 6 and Figure 7 The gasket 54 includes: a flat gasket 541, a corrugated gasket 542, and a bowl-shaped gasket 543. The flat gasket 541 increases the contact area, improves the stress distribution among the nut, rotating arm, fixed seat, and fixed pin, protects the contact surfaces of the rotating arm 51 and fixed seat 52, and adjusts the gap and height between components to achieve optimal working condition for the damping rotation mechanism 50. The corrugated gasket 542 uses elastic deformation to absorb vibration, compensate for axial deviation, and prevent component loosening, ensuring the structural stability of the damping rotation mechanism 50. The bowl-shaped gasket 543 provides elastic support, adjusts the direction of force, and assists in positioning and limiting. See also... Figure 6 and Figure 7 The damping rotation mechanism 50, from left to right, includes: a nut 53, a cup-shaped washer 543, a flat washer 541, a rotating arm 51, a flat washer 541, a fixed seat 52, a flat washer 541, a corrugated washer 542, a flat washer 541, a cup-shaped washer 543, and a fixing pin 55. (See also...)Figure 6 and Figure 7 The bowl-shaped washer 543 between the nut 53 and the rotating arm 51 has its bowl opening facing the rotating arm 51; the bowl-shaped washer 543 between the fixed seat 52 and the fixed pin 55 has its bowl opening facing the fixed seat 52.

[0045] In some embodiments, see Figure 2 and Figure 3 First magnetic strips 21 are respectively provided on both sides of the smoke collection chamber 20 at positions corresponding to the lower panel 40; second magnetic strips (not shown in the figure) are provided on both sides of the inner wall of the lower panel 40 at positions corresponding to the first magnetic strips 21. This arrangement ensures that the lower panel 40 is firmly fixed to the smoke collection chamber 20 when closed, thereby preventing the lower panel 40 from falling off during normal use of the range hood 100.

[0046] The range hood 100 provided by this utility model has a lower panel 40 made of metal sheet, so the lower panel 40 itself can be attracted to the first magnetic strip 21 set on the smoke collection chamber 20, without the need to set a second magnetic strip to be attracted to the first magnetic strip 21 at the corresponding position on both sides of the inner wall of the lower panel 40.

[0047] In some embodiments, see Figure 2 The top two sides of the inner wall of the upper panel 30 are rotatably connected to the smoke collection chamber 20 through a rotating mechanism 80. When the range hood 100 is turned on or off, the rotating mechanism 80 can control the upper panel 30 to rotate outward or inward relative to the smoke collection chamber 20, thereby opening or closing the upper panel 30.
