[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The unpowered oil fume separation device in this embodiment includes:

[0037] The oil-slinging pan assembly 10 here generally includes an outer pan and a plurality of blades arranged on the outer pan, the blades are arranged along the axis direction of the oil-slinging pan assembly, the blades are evenly spaced in the circumferential direction, and a chamber for oil smoke to enter is formed between the blades and the outer pan. When the oil-slinging pan assembly rotates, when the oil smoke entering the oil-slinging pan assembly passes through the gaps between the blades, the oil mist particles in the oil smoke are intercepted by the blades and separated and processed by the centrifugal force generated by the rotation of the blades.

[0038] The rotating shaft 20, the oil-slinging pan assembly 10 is connected to the rotating shaft 20, so that the oil-slinging pan assembly can rotate around the axis of the rotating shaft, and the rotating shaft 20 here is set to a hollow structure;

[0039] The nozzle 30 is disposed at one end of the rotating shaft 20. The nozzle 30 is located near the air inlet of the oil-slinging pan assembly and is used to form a water curtain at the air inlet of the oil-slinging pan assembly.

[0040] When the device is performing oil fume separation treatment, the oil fume entering the oil-spinning pan assembly is adsorbed by the water curtain formed by the nozzle, and then the oil fume is separated by the oil-spinning pan assembly, thereby improving the oil fume separation treatment efficiency and treatment effect.

[0041] In one embodiment, referring to Figure 4 The device includes a bracket assembly, and the rotating shaft 20 is arranged on the bracket assembly and is rotatably connected with the bracket assembly.

[0042] Specifically, the bracket assembly includes a fixed bracket 41 and a mounting bracket 42 for fixing the fixed bracket to the range hood, and the rotating shaft 20 is arranged on the fixed bracket 41 and is rotatably connected with the fixed bracket. A bearing 43 is arranged between the rotating shaft 20 and the fixed bracket 41 to rotatably connect the rotating shaft and the fixed bracket.

[0043] In this embodiment, when the device is installed on the range hood through the bracket assembly, the rotating shaft is configured to be rotatably connected to the fixed bracket, and the rotating shaft is fixedly connected to the oil-flinging tray assembly; when the oil-flinging tray assembly rotates, the rotating shaft is driven to rotate. At this time, while the oil-flinging tray assembly is rotating, the nozzle on the rotating shaft can be rotated synchronously, forming a rotating water curtain at the air inlet position of the oil-flinging tray assembly, thereby achieving a better oil fume separation effect.

[0044] In one embodiment, the rotating shaft 20 can also be fixedly arranged on the bracket assembly, and the oil-slinging pan assembly 10 is rotatably connected to the rotating shaft 20. Specifically, the rotating shaft 20 is fixedly arranged on the fixed bracket 41, and the oil-slinging pan assembly 10 is connected to the rotating shaft 20 through a bearing, so that the oil-slinging pan assembly can rotate on the rotating shaft.

[0045] In one embodiment, a telescopic joint 50 capable of extension and adjustment is provided between the rotating shaft 20 and the spray head 30. The telescopic joint 50 is a hollow structure, so that the spray head can be extended to a position close to the air inlet of the oil-slinging pan assembly, or retracted into the oil-slinging pan assembly. By providing a telescopic and adjustable telescopic joint, the position of the spray head is adjusted; when performing oil fume separation treatment, the spray head is adjusted to the air inlet position of the oil-slinging pan assembly to form a water curtain at the air inlet position; when the oil-slinging pan assembly needs to be cleaned, the spray head is adjusted to the inside of the oil-slinging pan, and the spray head is used to spray cleaning liquid to the oil-slinging pan assembly, so as to facilitate the cleaning operation of the oil-slinging pan assembly.

[0046] In one embodiment, referring to Figure 5 The expansion joint 50 includes a fixed sleeve 501 and a movable sleeve 502. The movable sleeve 502 is sleeved on the fixed sleeve 501 and slidably cooperates with the fixed sleeve.

[0047] In one embodiment, a rotation limiting structure capable of limiting the mutual rotation between the fixed sleeve 501 and the movable sleeve 502 is provided between the fixed sleeve 501 and the movable sleeve 502. The limiting structure here can be provided with a limiting groove on the fixed sleeve 501 and a matching limiting block on the movable sleeve 502. The relative rotation between the fixed sleeve and the movable sleeve is limited by the cooperation between the limiting block and the limiting groove, thereby ensuring the stability of the nozzle during operation.

[0048] In one embodiment, a water inlet joint 60 is disposed at the other end of the rotating shaft 20 , and the water inlet joint 60 provides the device with a medium for forming a water curtain or a cleaning liquid for cleaning.

[0049] In one embodiment, an air guide cover 70 is provided at the air inlet of the oil-slinging pan assembly to guide the oil smoke.

[0050] On the other hand, in one embodiment, a range hood is provided, comprising the unpowered oil fume separation device in the above embodiment, and the device is connected to the range hood via a mounting bracket.

[0051] When working, the oil-flinging tray assembly in the device rotates around the axis of the rotating shaft under the driving action of the wind force of the range hood, thereby realizing the unpowered oil fume separation operation of the oil-flinging tray assembly; at the same time, water is pumped into the rotating shaft, and a layer of water curtain is formed in front of the air inlet of the oil-flinging tray assembly through the nozzle, so that the oil fume passes through the water curtain before entering the oil-flinging tray assembly, and the oil fume particles are adsorbed by the water curtain, and then the oil fume particles are separated and processed by the rotating oil-flinging tray assembly. In this way, the device can realize two separation processes of oil fume, which greatly improves the efficiency and purification effect of oil fume purification.
