DETAILED DESCRIPTION

[0023] The following will be combined with the attached embodiment of the utility model Figure 1-5 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] The utility model is mainly aimed at top suction type range hoods.

[0026] like Figures 1 to 5 As shown, the utility model discloses an oil fume separation type oil screen, including a first oil screen 1 and an oil cup 3. An annular mounting ring 11 is arranged on the upper end of the first oil screen 1. The annular mounting ring 11 is provided with mounting holes for screw installation. This part is the same as the oil screen structure of a traditional top-suction range hood, so it will not be described in detail.

[0027] The upper end of the first oil net 1 is detachably provided with a second oil net 2, which is in the shape of a truncated cone. At the same time, the lower end of the second oil net 2 is open and hollow in the middle. The second oil net 2 is provided with an air flow channel 24 on the side wall, and the upper end surface of the air flow channel 24 is inclined.

[0028] The second oil net 2 is installed as follows: a mounting block 21 is provided on the outer side wall of the lower end of the second oil net 2, and correspondingly, a mounting groove 12 is provided in the middle of the inner side wall of the annular mounting ring 11, and a probe groove 13 is also provided on the upper end surface of the annular mounting ring 11. In this structure, the probe groove 13 is used for the mounting block 21 to enter the mounting groove 12. After the mounting block 21 of the second oil net 2 moves from the probe groove 13 to the mounting groove 12, the second oil net 2 can be rotated so that the mounting block 21 is located between the upper and lower end surfaces of the mounting groove 12.

[0029] The lower end of the first oil net 1 is open in design, and the oil cup 3 is still arranged at the lower end of the first oil net 1. However, in this structure, the oil cup 3 is no longer connected to the first oil net 1 but is detachably connected to the second oil net 2. Specifically, a first connecting rod 22 extends downward from the middle of the second oil net 2, and a second connecting rod 31 extends upward from the middle of the oil cup 3. The first connecting rod 22 and the second connecting rod 31 are threadedly connected.

[0030] In order to facilitate the disassembly of the oil cup 3, a clamping block 14 and a limiting wall 15 are provided in the mounting groove 12, and the clamping block 14 and the limiting wall 15 are used to abut against the side wall of the mounting block 21. At the same time, the thickness of the clamping block 14 is less than the thickness of the mounting groove 12, and at least one mounting block 21 can be accommodated between the clamping block 14 and the limiting wall 15. After the mounting block 21 enters the mounting groove 12, the second oil net 2 can continue to be rotated, so that the mounting block 21 on the second oil net 2 is squeezed into the gap between the clamping block 14 and the mounting groove 12, and rotated to between the clamping block 14 and the limiting wall 15. At this time, when the oil cup 3 and the second oil net 2 are connected or disassembled, the clamping block 14 and the limiting wall 15 can prevent the second oil net 2 from rotating.

[0031] An oil collecting ramp 23 is arranged between the upper end surface inside the oil net and the outer side wall of the first connecting rod 22, and the oil collecting ramp 23 is inclined downward toward the first connecting rod 22. The working principle of this structure is that after the oil is blocked by the upper end surface inside the oil net, the oil can be collected along the oil collecting ramp 23 to the outer side wall of the first connecting rod 22, and then flow downward and be collected by the oil cup 3.

[0032] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
