The depth of the first positioning notch 11 can be less than the size of the first end of the rod body 2, can be equal to the size of the first end of the rod body 2, or can be greater than the size of the first end of the rod body 2.

[0052] In an embodiment of the present invention, please refer to Figure 5 , the second ends of the rod bodies 2 are fixedly connected to the baffle 3. Using the baffle 3 to fix the second ends of the plurality of rod bodies 2 not only fixes the plurality of rod bodies 2, but also installs the baffle 3 on one side end of the protective net main body to form the protective net structure 100, which can further simplify the structure. It can be understood that the manner in which the second ends of the rod bodies 2 are fixedly connected to the baffle 3 is not limited, and can be bonding, clamping, welding, etc., which are not limited in the present invention.

[0053] Specifically, in an embodiment of the present invention, please refer to Figure 7 , a plurality of second positioning notches 31 are arranged at intervals along the length direction of the baffle 3 for correspondingly mounting a plurality of the rod bodies 2. By arranging a plurality of second positioning notches 31 on the baffle 3, the mounting positions of the plurality of rod bodies 2 on the baffle 3 are defined.

The depth of the second positioning notch 31 can be less than the size of the second end of the rod body 2, can be equal to the size of the second end of the rod body 2, or can be greater than the size of the second end of the rod body 2.

[0055] The present invention also proposes an oil fume machine 1000, please refer to Figures 1 to 4, the range hood 1000 includes a blower housing 200, a smoke collecting hood 300, and a baffle 3. A blower assembly is arranged inside the blower housing 200, and the blower housing 200 is provided with an oil nozzle 220 for guiding oil. The smoke collecting hood 300 is installed below the blower housing 200 and connected to the blower housing 200. The smoke collecting hood 300 has a rear side wall 310 extending in the up and down direction. The baffle 3 is installed at the junction of the smoke collecting hood 300 and the blower housing 200. The lower end of the baffle 3 is used to form a liquid outlet gap with the rear side wall 310, and the upper end is inclined upward in the direction away from the rear side wall 310. The outlet end of the oil nozzle 220 is located directly above the baffle 3.

[0056] The technical solution of the present utility model installs the baffle 3 at the junction of the smoke collecting hood 300 and the blower housing 200. The baffle 3 is inclined. The oil discharged from the oil nozzle 220 flows out from its outlet end, first falls on the inclined baffle 3, then flows down along the baffle 3, and then flows out from the liquid outlet gap, and flows down along the rear side wall 310 of the smoke collecting hood 300 into the oil cup of the range hood 1000. The baffle 3 can not only guide the oil to the rear side wall 310 of the smoke collecting hood 300, so that the oil flows down along the rear side wall 310 of the smoke collecting hood 300 into the oil cup of the range hood 1000, but also slow down the flow rate of the oil, thereby effectively preventing the oil from dripping onto the stove top of the kitchen and being conducive to keeping the stove top clean.

[0057] It can be understood that the installation method of the baffle 3 and the smoke collecting hood 300 is not limited. It can be bonded, clamped, welded, screwed, etc. The present utility model does not make a limitation.

[0058] In addition, the smoke collecting hood 300 may further have two side walls 320 oppositely arranged in the horizontal direction. The two lateral ends of the baffle 3 in the horizontal direction can form a diversion gap with at least one of the side walls 320, so as to divert the oil accumulated between the baffle 3 and the rear side wall 310 from the diversion gap to the side wall 320 and flow down along the side wall 320 of the smoke collecting hood 300, which can play a role in shunting and is conducive to the discharge of oil. It can be understood that the diversion gap can be one, and a diversion gap is formed between one of the lateral ends of the baffle 3 in the horizontal direction and the adjacent side wall 320. The diversion gap can also be two, and diversion gaps are formed between the two lateral ends of the baffle 3 in the horizontal direction and the adjacent side walls 320 respectively.

[0059] Further, in the embodiment of the present utility model, the width of the liquid outlet gap is less than or equal to 5 mm. When the width of the liquid outlet gap is within the above range, the problem of dripping of the oil flowing out of the liquid outlet gap can be effectively avoided, and it is ensured that the oil flowing out of the liquid outlet gap flows downward along the rear side wall 310 of the smoke collecting hood 300. It can be understood that the width of the liquid outlet gap can be 5 mm, 4.5 mm, 4 mm, 3.5 mm, 3 mm, etc., and the present utility model does not make any limitations.

[0060] The included angle between the baffle 3 and the rear side wall 310 is not limited, as long as the baffle 3 can divert the oil flowing out of the outlet end of the oil nozzle 220 to the rear side wall 310. Further, in the embodiment of the present utility model, the included angle between the baffle 3 and the rear side wall 310 is 30° - 60°. When the included angle between the baffle 3 and the rear side wall 310 is within the above range, the flow velocity of the oil is more appropriate, and the diversion effect of the baffle 3 is better. The included angle between the baffle 3 and the rear side wall 310 can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc., and the present utility model does not make any limitations.

[0061] The smoke collecting hood 300 is mainly used to capture and gather the cooking fumes generated during the cooking process, so as to discharge the fumes outdoors through the fan system to keep the kitchen air fresh. Therefore, an air inlet is provided on the smoke collecting hood 300 to allow the fumes to enter the smoke collecting hood 300.

[0062] In the embodiment of the present utility model, please refer to Figure 1 and Figure 8 , a guiding member 400 extending in the up-down direction is provided on the rear side wall 310;

[0063] The middle part of the baffle 3 is arranged opposite to the guiding member 400, and an avoidance notch 32 is provided at the lower end of the baffle 3, and the avoidance notch 32 is adapted to the guiding member 400.

[0064] By providing the guiding member 400 extending in the up-down direction on the rear side wall 310, a left-right double flow channel can be formed at the front end of the air intake, making the suction and discharge of the cooking fumes smoother; at the same time, in order to avoid the guiding member 400 affecting the installation of the baffle 3, an avoidance notch 32 is provided at the lower end of the baffle 3, so that the baffle 3 does not interfere with the guiding member 400 during the installation process, facilitating the installation of the baffle 3 and the guiding member 400.

[0065] The flow guide member 400 can be entirely fixedly arranged. Specifically, the flow guide member 400 includes an upper rectifying portion 410 and a lower rectifying portion 420 arranged in sequence along the up-down direction. Both the upper rectifying portion 410 and the lower rectifying portion 420 are fixedly installed on the rear side wall 310 of the smoke collecting hood 300. Among them, the opposite two sides of the upper rectifying portion 410 in the front-back direction of the smoke collecting hood 300 are respectively in contact with the cavity wall of the inner cavity of the smoke collecting hood 300. Rectifying side surfaces are formed on the opposite two sides of the upper rectifying portion 410 in the left-right direction of the smoke collecting hood 300. The rectifying side surfaces extend in the direction from the air inlet to the smoke outlet and are spaced from the cavity wall in the left-right direction. The distance between the two rectifying side surfaces is set to become smaller from the rear to the front. After the cooking fume enters the inner cavity through the air inlet, it can be rectified by the upper rectifying portion 410 of the flow guide member 400, so that the cooking fume enters the smoke outlet in an approximately parallel manner, thereby preventing the cooking fume from colliding at the smoke outlet, reducing the probability of generating collision noise, and thus reducing the noise of the range hood 1000. And because the upper rectifying portion 410 can rectify the cooking fume into an approximately parallel manner to enter the smoke outlet, the probability of generating eddy currents on both sides of the cooking fume can be reduced, the probability of generating aerodynamic noise can be reduced, and further the noise of the range hood 1000 can also be reduced. Further, since the flow rate of the cooking fume at the position closer to the rear is larger and more concentrated than that at the position closer to the front, the distance between the two rectifying side surfaces is set to become smaller from the rear to the front. Furthermore, the larger-flow cooking fume closer to the rear can be better rectified, the rectifying effect can be improved, and the noise of the range hood 1000 can be reduced.

[0066] The upper rectifying portion 410 of the flow guide member 400 can also be movably arranged. Specifically, in the embodiment of the present invention, the flow guide member 400 includes an upper rectifying portion 410 and a lower rectifying portion 420 arranged in sequence along the up-down direction. The lower rectifying portion 420 is fixedly installed on the rear side wall 310, and the upper rectifying portion 410 is swingably installed horizontally at the upper end of the lower rectifying portion 420. The lower rectifying portion 420 is fixedly installed on the rear side wall 310 of the smoke collecting hood 300, and the upper rectifying portion 410 is arranged to swing horizontally, so that the cross-sectional area size in the left-right air inlet path of the range hood 1000 changes under the swing of the upper rectifying portion 410, and the air inlet volume ratio on the left and right sides is changed. Therefore, accurate smoking can be carried out for cooking on the left or right side of the cooking stove, the single-side smoking effect can be improved, and it is suitable for single-stove / single-side use of the cooking stove or use scenarios such as one steaming and one stir-frying, so that the smoking effect is optimally matched and the noise is relatively low. In addition, when an avoidance notch 32 is provided at the lower end of the baffle 3, the swing displacement of the upper rectifying portion 410 needs to be considered to avoid interference with the upper rectifying portion 410.

[0067] Further, in the embodiment of the present utility model, the range hood 1000 further includes a protective net structure 100. The baffle 3 is the baffle 3 in the protective net structure 100. The specific structure of the protective net structure 100 refers to the above embodiment. Since the range hood 1000 adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0068] The above are only exemplary embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
