[0037] like Figures 1 to 3 As shown, an embodiment of the utility model provides a smoke collecting device and a range hood, the range hood comprising an exhaust device and the above-mentioned smoke collecting device, wherein the smoke collecting device has a smoke collecting chamber and a smoke inlet 125 connected to the smoke collecting chamber, the top of the smoke collecting device is provided with a smoke exhaust port connected to the smoke collecting chamber, the exhaust mechanism comprises a bellows connected to the top of the smoke collecting device and an exhaust fan arranged in the bellows, the lower end of the bellows is connected to the smoke exhaust port, the exhaust fan is used for exhausting oil smoke, so that negative pressure is formed at the smoke inlet 125, so as to promote the oil smoke to enter the bellows through the smoke inlet 125, the smoke collecting chamber and the smoke exhaust port, and be discharged to the outside of the range hood through the exhaust fan.

[0038] like Figures 1 to 3 As shown, the smoke collecting device includes a smoke collecting hood 1, an oil baffle plate 2 and a lower decorative plate 3, wherein the smoke collecting hood 1 has an oil collecting chamber 11, the smoke collecting chamber includes an oil collecting bottom plate 12 forming the lower bottom of the oil collecting chamber 11, the oil collecting bottom plate 12 extends obliquely downward from front to rear, and an oil guide hole 127 is opened on the oil collecting bottom plate 12; the oil baffle plate 2 is located below the rear end of the oil collecting bottom plate 12, a first oil collecting trough 100 is formed between the oil baffle plate 2 and the oil collecting bottom plate 12, the oil guide hole 127 is at least partially located at the lowest position of the first oil collecting trough 100, and the first oil collecting trough 100 is connected with the oil collecting chamber 11 through the oil guide hole 127; the lower decorative plate 3 is located at the rear end of the oil collecting bottom plate 12 and below the oil baffle plate 2.

[0039] In this embodiment, the lower decorative panel 3 is a glass panel, and the smoke collecting hood 1 includes a smoke collecting front panel and a smoke collecting rear panel 15 which are spaced apart from each other along the front and rear and two smoke collecting side panels which are spaced apart from each other and are spaced apart from each other on the left and right and are spaced apart from each other. The two smoke collecting side panels, the smoke collecting front panel, the smoke collecting rear panel 15, the oil collecting bottom panel 12, and the oil collecting top panel connecting the oil collecting front panel and the smoke collecting rear panel 15 form a smoke collecting cavity, and the bottom space of the smoke collecting cavity forms an oil collecting cavity 11.

[0040] The lower decorative plate 3 is arranged at the rear end of the oil collecting bottom plate 12 and below the oil baffle plate 2. The oil baffle plate 2 is used to separate the oil collecting bottom plate 12 and the lower decorative plate 3. The oil stains attached to the oil collecting bottom plate 12 will fall onto the oil baffle plate 2 instead of the lower decorative plate 3. The oil stains on the oil baffle plate 2 are gathered in the first oil collecting groove 100 surrounded by the oil collecting bottom plate 12 and the oil baffle plate 2. The oil stains in the first oil collecting groove 100 enter the oil collecting cavity 11 through the oil guide hole 127, and the oil stain discharge effect is good.

[0041] Furthermore, if Figures 1 to 3 As shown, the smoke collecting device also includes an oil cup 4, which is installed below the rear end of the smoke collecting hood 1. An oil collecting hole 124 is provided on the oil collecting bottom plate 12, and the oil collecting cavity 11 is connected with the oil cup 4 through the oil collecting hole 124; the lower decorative panel 3 extends downward from front to back, and the front end of the lower decorative panel 3 extends out of the oil baffle plate 2, and the rear end of the lower decorative panel 3 is always located on the inner side of the oil cup 4, and the lower decorative panel 3 and the oil baffle plate 2 are spaced apart in the vertical direction.

[0042] Since the front end of the lower decorative plate 3 extends out of the oil baffle plate 2, the lower decorative plate 3 is used to cover the oil baffle plate 2, thereby improving the aesthetic effect of the smoke collecting device. The lower decorative plate 3 and the oil baffle plate 2 are arranged at intervals in the vertical direction, so that the lower decorative plate 3 and the oil baffle plate 2 can form an oil guide channel 200. Since the front end of the lower decorative plate 3 extends out of the oil baffle plate 2, when the oil attached to the oil collecting bottom plate 12 drips onto the oil baffle plate 2, a small amount of oil will splash onto the lower decorative plate 3, and the oil splashed onto the oil baffle plate 2 can be guided to the oil cup 4 through the oil guide channel 200.

[0043] It should be noted that the lower decorative plate 3 is mounted on the smoke collecting hood 1 , and the mounting method of the lower decorative plate 3 and the smoke collecting hood 1 is the prior art in the art, which will not be described in detail here.

[0044] Furthermore, if Figures 1 to 3 As shown, the oil baffle plate 2 extends downward from front to back. Such arrangement is conducive to the oil dirt in the first oil collecting groove 100 entering the oil collecting chamber 11 through the oil guide hole 127.

[0045] Furthermore, if Figures 1 to 3 As shown, the oil baffle plate 2 is glued and fixed to the smoke hood 1. The installation method is simple, fast and low-cost; and there is no need to process mounting holes on the oil baffle plate 2, which simplifies the processing of the oil baffle plate 2. In this embodiment, the rear end edge of the oil baffle plate 2 and the left and right edges of the oil baffle plate 2 are arranged close to the lower surface of the oil collecting bottom plate 12, and the front end of the oil baffle plate 2 is spaced from the oil collecting bottom plate 12, so that a first oil collecting trough 100 is formed between the oil baffle plate 2 and the oil collecting bottom plate 12. Such a design can prevent the oil stains in the first oil collecting trough 100 from leaking through the connection position between the oil baffle plate 2 and the oil collecting bottom plate 12.

[0046] Furthermore, if Figures 1 to 3 As shown, the oil collecting bottom plate 12 is concave to form a smoke collecting cavity 126 with an opening at the lower end, and a smoke inlet 125 connected to the smoke collecting cavity is provided at the bottom of the smoke collecting cavity 126. After the oil smoke enters the smoke collecting cavity 126, it enters the smoke collecting cavity through the smoke inlet 125.

[0047] The rear wall of the smoke collecting chamber 126 extends downwardly from front to rear; the rear end edge of the oil baffle plate 2 is located on the rear side of the smoke collecting chamber 126 and is close to the lower open end surface of the smoke collecting chamber 126, part of the oil guide holes 127 are arranged on the rear wall of the smoke collecting chamber 126, and the other part of the oil guide holes 127 are arranged on the lower open end surface of the smoke collecting chamber 126.

[0048] The rear wall of the smoke collecting chamber 126 extends downwardly from front to back, which is beneficial for the oil stains attached to the rear wall of the smoke collecting chamber 126 to be guided into the first oil collecting trough 100 surrounded by the rear wall of the smoke collecting chamber 126 and the oil baffle 2. Since the amount of oil stains attached to the smoke collecting chamber 126 is large, some oil guide holes 127 are arranged on the rear wall of the smoke collecting chamber 126, and the other part of the oil guide holes 127 are arranged on the lower open end surface of the smoke collecting chamber 126. The oil stains in the first oil collecting trough 100 can be promptly guided into the oil collecting chamber 11 through the oil guide holes 127.

[0049] In this embodiment, two smoke collecting chambers 126 are provided, and the two smoke collecting chambers 126 are spaced apart along the left-right direction of the smoke collecting hood 1 .

[0050] Furthermore, if Figure 3 and Figure 4As shown, the inner wall of the smoke hood 1 is provided with an upwardly protruding mounting boss 122, the upper surface of the mounting boss 122 is higher than the lowest end of the oil guide hole 127, and a harness fixing structure 123 is provided on the upper surface of the mounting boss 122. The harness inside the smoke hood 1 is fixed by the harness fixing structure 123. Since the upper surface of the mounting boss 122 is higher than the lowest end of the oil guide hole 127, and the harness fixing structure 123 is arranged on the upper surface of the mounting boss 122, the harness can be prevented from contacting the oil dirt guided from the oil guide hole 127 to the oil collecting chamber 11, thereby preventing the harness from being contaminated by the oil dirt.

[0051] In this embodiment, the mounting boss 122 is located at the rear side of the oil guide hole 127. Since the oil collecting bottom plate 12 extends downwardly from front to back, the upper surface of the mounting boss 122 can be higher than the lowermost end of the oil guide hole 127. The wire harness fixing structure 123 is a cable tie buckle, and the wire harness is tied to the cable tie buckle by a cable tie.

[0052] Furthermore, if Figure 4 As shown, a plurality of wire harness fixing structures 123 are provided, and the plurality of wire harness fixing structures 123 are spaced apart along the left-right direction of the smoke collecting hood 1 to meet the wire harness fixing requirements.

[0053] Furthermore, if Figure 4 As shown, there are multiple mounting bosses 122, and the multiple mounting bosses 122 are spaced apart along the left and right directions of the smoke hood 1, and at least one tie buckle is provided on each mounting boss 122. In this embodiment, some mounting bosses 122 are provided with one tie buckle, and some mounting bosses 122 are provided with two or more tie buckles to meet the wiring harness fixing requirements.

[0054] Furthermore, if Figure 3 As shown, the outer wall of the oil collecting bottom plate 12 is recessed toward the inner wall of the oil collecting bottom plate 12, so that the inner bottom wall of the oil collecting bottom plate 12 forms a convex mounting boss 122. If the mounting boss 122 is formed by stamping, it is beneficial to improve the structural strength of the oil collecting bottom plate 12.

[0055] Furthermore, if Figure 4 As shown, a harness mounting plate 16 is fixed to the inner wall of the oil collecting chamber 11, and a wiring channel 17 is formed between the harness mounting plate 16 and the inner wall of the oil collecting chamber 11, and the harness fixed to the tie buckle by the tie can extend into the wiring channel 17 and pass out. In this embodiment, the harness mounting plate 16 is mounted on the smoke collecting rear plate 15 by a plurality of fasteners.

[0056] Furthermore, if Figure 1 and Figure 3As shown, the inner bottom wall of the oil collecting bottom plate 12 is recessed with a second oil collecting groove 121, and the second oil collecting groove 121 is located at the rear side of the mounting boss 122. Such a configuration is conducive to the oil entering the oil collecting cavity 11 through the oil guide hole 127 to enter the second oil collecting groove 121 along the inner bottom wall of the oil collecting cavity 11 under the action of gravity, thereby reducing the probability that the oil in the oil collecting cavity 11 exceeds the upper surface of the mounting boss 122.

[0057] In this embodiment, the oil collecting hole 124 is opened on the bottom wall of the second oil collecting groove 121 , and the oil in the second oil collecting groove 121 falls into the oil cup 4 below through the oil collecting hole 124 .

[0058] Furthermore, if Figure 5 As shown, the smoke hood 1 is provided with two first positioning members 13 spaced apart along the left-right direction thereof, and the oil baffle plate 2 is sandwiched between the two first positioning members 13. In this embodiment, the first positioning member 13 is protruding from the outer bottom wall of the oil collecting bottom plate 12, and the oil baffle plate 2 is positioned along the left-right direction by using the two first positioning members 13, so that the position accuracy of the oil baffle plate 2 is high when the oil collecting bottom plate 12 and the oil baffle plate 2 are glued and fixed.

[0059] In this embodiment, the inner bottom wall of the oil collecting bottom plate 12 is concave outwards so that the outer bottom wall of the oil collecting bottom plate 12 forms the above-mentioned first positioning member 13 which is convex, which is beneficial to improve the structural strength of the oil collecting bottom plate 12. For example, the above-mentioned first positioning member 13 is formed by stamping.

[0060] Furthermore, the lower surface of the oil baffle plate 2 is higher than the lowermost end of the first positioning member 13, and the upper surface of the lower decorative plate 3 abuts against the two first positioning members 13 respectively to ensure that the oil baffle plate 2 and the lower decorative plate 3 are spaced apart in the vertical direction.

[0061] Furthermore, if Figure 5 As shown, the fume hood 1 is provided with a second positioning member 14 located at the rear side of the oil baffle plate 2, and the rear end surface of the oil baffle plate 2 abuts against the second positioning member 14. In this embodiment, the second positioning member 14 is convexly arranged on the outer bottom wall of the oil collecting bottom plate 12, and the oil baffle plate 2 is positioned along the front-to-back direction by using the second positioning member 14. When the oil collecting bottom plate 12 and the oil baffle plate 2 are glued and fixed, the position accuracy of the oil baffle plate 2 is high.

[0062] In this embodiment, the inner bottom wall of the oil collecting bottom plate 12 is recessed outward to form the second oil collecting groove 121, and the outer bottom wall of the oil collecting bottom plate 12 is formed with the second locating member 14 protruding, which is beneficial to improve the structural strength of the oil collecting bottom plate 12. For example, the second oil collecting groove 121 is formed while the second locating member 14 is formed by stamping.

[0063] In addition, the above are only preferred embodiments of the present invention and the technical principles used.
