DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0025] The device can be clamped or adsorbed on the range hood by setting the suction assembly 6 and the clamping assembly 7. When the range hood shell is flat and smooth, the clamping assembly 7 can be used to adsorb the disc tightly to generate strong suction force and firmly fix it. When the frame or protruding structure is encountered, the suction assembly 6 is used to adjust the opening and closing degree of the flexible elastic clamping arm to stably clamp it, so as to adapt to various styles of range hoods and ensure stable use.

[0026] Specifically, the angle adjusting assembly 3 includes a connecting block two 32 and a rotating rod 34. The rotating rod 34 is fixedly installed at the middle of the front end of the connecting block one 2. The connecting block two 32 is provided with a rotating hole 33 at one end close to the connecting block one 2, which can rotate with the rotating rod 34. A damping rubber layer 331 is glued and installed on the inner surface of the rotating hole 33. A connecting plate 31 is fixedly installed on the upper side of one end of the connecting block two 32 along the width direction. The back end of the connecting plate 31 is attached to the front end of the connecting arm 1.

[0027] The induction assembly 5 includes a controller 51 and an infrared sensor 52. The controller 51 and the infrared sensor 52 are fixedly installed at the front end of the connecting plate 31. The controller 51 and the infrared sensor 52 are electrically connected.

[0028] After being installed on the fan, the induction assembly 5 rotates on the connecting block one 2 on one side of the connecting arm 1 with the rotating rod 34 as the axis through the connecting plate 31. Thus, the angle of the induction assembly 5 can be adjusted to accurately face the source of oil fume, and the induction monitoring function can be efficiently played. The damping rubber layer 331 is glued and installed on the outer surface of the rotating rod 34. The damping effect between the damping rubber layer 331 and the rotating rod 34 can avoid unnecessary sliding of the connecting plate 31 after being unfolded.

[0029] The back end of the connecting plate 31 is attached to the top end of the connecting arm 1. Thus, the connecting arm 1 can avoid limiting the connecting plate 31 when the connecting plate 31 is rotated.

[0030] The controller 51 and the infrared sensor 52 in the scheme both belong to the prior art. The model of the infrared sensor 52 is MTN6005-0001. The model of the controller 51 is AHK-360A. The working principle is that the infrared sensor 52 detects the oil fume generated during cooking and transmits the signal to the controller 51. The controller 51 analyzes and processes the signal according to the preset program, issues instructions to the fan according to the oil fume amount, and operates the fan at low power when the oil fume amount is small and operates the fan at high power when the oil fume amount is large, so as to ensure the air cleanliness in the kitchen.

[0031] Specifically, the clamping assembly 7 comprises an L-shaped seat 71 fixedly installed at the leftmost top end of the connecting arm 1, a threaded hole 711 is formed through the top end of the L-shaped seat 71 in the horizontal direction, and a threaded rod 72 is screw-mounted in the inner cavity surface of the threaded hole 711;

[0032] The threaded rod 72 is rotatably installed at one end of the threaded hole 711, and a clamping plate 74 is fixedly installed at the other end of the threaded rod 72, and two rubber pads 741 are respectively glued on the opposite surfaces of the clamping plate 74 and the connecting arm 1.

[0033] In the scheme, the clamping plate 74 and the connecting arm 1 first need to be twisted and turned by the twisting disc 73 during use, the threaded rod 72 is driven by the twisting disc 73 to slide downward along the axis of the threaded hole 711, so that the clamping plate 74 and the connecting arm 1 are close to each other, so that the clamping plate 74 and the connecting arm 1 clamp the fan, and the two rubber pads 741 glued between the opposite surfaces of the clamping plate 74 and the connecting arm 1 can avoid hard contact with the fan clamping surface during clamping, and protect the fan clamping surface from being damaged during clamping.

[0034] Specifically, the suction assembly 6 comprises an L-shaped air hole 61 and a guide ring 63, the L-shaped air hole 61 is formed through the connecting arm 1, the input port of the L-shaped air hole 61 is arranged at the left end of the connecting arm 1, the output port of the L-shaped air hole 61 is arranged at the middle of the bottom end of the connecting arm 1, and the guide ring 63 is fixedly installed at the middle of the back end of the connecting arm 1.

[0036] In the scheme, when the suction installation is needed, the suction cup 4 at the bottom end of the connecting arm 1 is first pressed on the fan, then the J-shaped pull rod 62 is pulled, the J-shaped pull rod 62 drives the piston 621 to slide outward, the gas between the suction cup 4 and the connecting arm 1 is sucked out through the L-shaped air hole 61, the air between the suction cup 4 and the fan is completely sucked out after the suction cup 4 is adsorbed to the fan, and the adsorption capacity of the suction cup 4 is enhanced.

[0037] The tension of the spring 65 pushes the J-shaped pull rod 62 outward, avoids the J-shaped pull rod 62 from driving the piston 621 to slide into the inner cavity of the L-shaped air hole 61 after the suction cup 4 is adsorbed on the fan, and releases the effect of the suction cup 4 from being attracted by the negative pressure of the connecting arm 1.
