As shown in fig. 2, the cross section of the air inlet nozzle 422 is smaller than that of the air outlet 110, when the air flow enters the air inlet nozzle 422 through the air outlet 110, the air flow can form irregular movement after passing through the air inlet nozzle 422 due to the smaller air inlet nozzle 422, and can form a vortex, and the vortex air flow can make a sound when passing through the sound-generating hole 423.

The lower end of the vent chamber 424 may be isolated from the oil by a baffle so that the air flow entering the vent chamber 424 after passing through the air outlet 110 can only exit through the generating holes 423, which ensures that the whistle 420 can make a sound. .

The upper end wall of the sound hole 423 is horizontal, and the lower end wall of the sound hole 423 inclines downwards from inside to outside to form a sharp-angled structure, so that the vortex airflow can flow out of the sound hole 423 to emit sound more conveniently.

When the float 410 floats upwards, the upper end of the whistle body 420 abuts against the periphery of the air outlet 110, and the air inlet 421 is in butt joint with the air outlet 110. That is, when the oil collecting container 300 is in a full oil state, the air inlet 421 and the air outlet 110 can form a relatively sealed butt joint, which is beneficial to the air flow passing through the air outlet 110 to enter the air inlet 421 more, reduces or avoids air leakage, reduces air flow waste, and is more beneficial to the whistle 420 to make a sound or make a relatively high sound. The whistle body 420 can be an integral structure, in this embodiment, as shown in fig. 2-5, the whistle body 420 includes a flow guide cover 425 at the upper end portion, the flow guide cover 425 can be detachably clamped at the upper end portion of the whistle body 420, the flow guide cover 425 can be made of a material different from that of the whistle body 420, for example, the flow guide cover 425 can be made of a rubber material with better sealing performance, so that the air inlet 421 and the air outlet 110 form a more sealed butt joint. The thin strip-shaped air inlet nozzle 422 is positioned on the flow guide cover 425, when the floater 410 floats upwards, namely the oil collecting container 300 is in a full oil state, the flow guide cover 425 abuts against the periphery of the air outlet 110 and forms sealing connection, the upper surface of the flow guide cover 425 is concave downwards to form a concave surface, and the concave surface gradually converges towards the air inlet nozzle 422. More directly concentrate the air flow to the air inlet nozzle 422 so that the air flow passing through the air inlet nozzle 422 is stronger and forms a vortex more easily to give a louder warning sound.

Further, as shown in fig. 3 and 4, the float 410 is located at the lower end of the whistle body 420 and is disposed symmetrically with respect to the central axis of the whistle body 420. Therefore, the gravity and the buoyancy of the two sides of the whistle body 420 are equivalent, the whistle body 420 is not easy to incline in the floating process, and can be more accurately butted with the air outlet 110.

As shown in fig. 6 and 7, the oil collecting container 300 has a limiting rib 310 capable of preventing the airflow sound generating device 400 from moving horizontally, and the limiting rib 310 has an oil through hole 320. Because the oil collecting container 300 is usually long, and the length of the airflow sound generating device 400 is far less than that of the oil collecting container 300, the limiting convex rib 310 can prevent the airflow sound generating device 400 from shaking left and right, which is beneficial to the accuracy of butt joint of the whistle body 420 and the air outlet 110, and the oil through hole 320 can communicate the oil in the oil collecting container 300, so that the oil can be uniformly distributed in the oil collecting container 300, and the condition of different depths is avoided. The limiting convex rib 310 is further provided with a blocking sheet 330 protruding towards the inner side, and the blocking sheet 330 is located at the front end portion of the limiting convex rib 310, so that the airflow sounding device 400 can be arranged at the back, the back and forth movement of the airflow sounding device 400 is reduced or avoided, and oil drops on the front panel of the range hood are prevented from dropping on the airflow sounding device 400.

Further, as shown in fig. 4 and 5, the inner cavity of the float 410 is provided with an upward opening, a sealing plate 411 is covered on the opening, a through hole is formed in the middle of the sealing plate 411, and the whistle body 420 penetrates through the through hole upwards. The sealing plate 411 can prevent foreign matters such as oil stains from accumulating in the float 410, and the reminding precision is ensured.

As shown in fig. 2 to 4, the bottom surface of the float 410 has a support part 412 protruding downward, and the support part 412 can reduce the contact surface between the float 410 and the oil container 300, reduce the possibility of adhesion, and reduce the occurrence of the situation that the float 410 cannot rise due to adhesion when the amount of oil increases.
