[0034] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0035] Please see Figures 1 to 5 This utility model provides a smoke generating device, which is applied to a range hood 5 and includes a support component 1, a heating component 2, a splash-proof component 3 and a liquid dripping component 4.

[0036] Please refer to the following in this embodiment: Figure 1 The supporting component 1 is a cabinet. The side of the cabinet is "L" shaped, which is used to install and fix the heating component 2, the splash-proof component 3, and the liquid dripping component 4, so as to facilitate better smoke generation.

[0037] The heating assembly 2 includes a cooktop 21 and a pot 22. The cooktop 21 is detachably mounted on the support assembly 1, and the pot 22 is placed on the cooktop 21. Specifically, the cooktop 21 is detachably mounted on the support assembly 1 by a snap-fit ​​connection. The cooktop 21 is a stove, and the pot 22 is a wok. Two of each type are provided to better and more accurately simulate smoke generation.

[0038] A splash guard 3 is placed inside the pot 22. The splash guard 3 includes a splash guard housing 31 and a cover plate 32. The splash guard housing 31 has a first smoke-generating channel. The cover plate 32 is detachably installed on the splash guard housing 31, and there is a gap between the cover plate 32 and the splash guard housing 31. The cover plate 32 has a second smoke-generating channel, and the projections of the first smoke-generating channel and the second smoke-generating channel are misaligned. Specifically, the orthographic projections of the first smoke-generating channel and the second smoke-generating channel are misaligned. With the setup of the first and second smoke-generating channels, after the cookware 22 generates oil fumes, the fumes pass through the first and second smoke-generating channels in sequence. When the oil splashes out of the cookware 22, the anti-splash housing 31 blocks the oil. After the oil passes through the first smoke-generating channel, the cover plate 32 blocks the oil. The anti-splash housing 31 and the cover plate 32 work together to block the oil splashed out of the cookware 22. The blocked oil will flow back into the pot due to gravity, thus achieving reheating.

[0039] The dripping end of the liquid dripping assembly 4 is located above the cover plate 32. The placement of the dripping end of the liquid dripping assembly 4 above the cover plate 32 allows the oil to flow smoothly into the cookware 22.

[0040] This utility model discloses a smoke-generating device. During installation, the user fixes the liquid dripping component 4 and the stove 21 onto the support component 1, places the pot 22 on the stove 21, and installs the anti-splash component 3 inside the pot 22. After the smoke-generating device is installed, it is confirmed that there is oil in the liquid dripping component 4. During use, the user turns on the stove 21 and the liquid dripping component 4 respectively. The oil dripping from the dripping end of the liquid dripping component 4 drips onto the anti-splash component 3. The oil flows sequentially through the second smoke-generating channel and the first smoke-generating channel into the pot 22. The stove 21 heats the oil in the pot 22, and the heated oil produces smoke that is sequentially emitted from the first smoke-generating channel and the second smoke-generating channel, thus generating smoke. When the oil splashes in the cookware 22, the anti-splash housing 31 blocks the oil. After the oil passes through the first smoke-generating channel, the cover plate 32 blocks the oil. The anti-splash housing 31 and the cover plate 32 block the oil splashed in the cookware 22. The blocked oil will flow back into the pot for reheating. This not only prevents oil from splashing, but also allows the dripping oil to disperse the smoke, making the smoke more dispersed and improving the smoke generation efficiency. This makes the performance test of the range hood 5 more accurate.

[0041] Based on the above embodiments, please also refer to... Figure 3 and Figure 4 The splash-proof component 3 of this utility model also includes a fixing post 33. Both the splash-proof housing 31 and the cover plate 32 have fixing holes. The two ends of the fixing post 33 are detachably installed into the corresponding fixing holes on the splash-proof housing 31 and the cover plate 32. Through the fixing post 33, the splash-proof housing 31 and the cover plate 32 are connected. During installation, the user fixes the two ends of the fixing post 33 into the fixing holes on the splash-proof housing 31 and the cover plate 32, thereby achieving a more stable fixation of the splash-proof housing 31 and the cover plate 32.

[0042] Based on the above embodiments, please also refer to... Figure 3 and Figure 4 This utility model provides multiple first and second smoke-generating channels. The multiple first smoke-generating channels are radially spaced from the center of the splash-proof housing 31, and the multiple second smoke-generating channels are radially spaced from the center of the cover plate 32. In this embodiment, multiple first and second smoke-generating channels are provided, so that both the splash-proof housing 31 and the cover plate 32 form a grid. After the cover plate 32 is placed on the splash-proof housing 31, the grid on the cover plate 32 is misaligned with the grid on the splash-proof housing 31, thereby better shielding the oil splashed from the pot 22 and also better dispersing the smoke.

[0043] Based on the above embodiments, please also refer to... Figure 3 and Figure 4The opening size of the first smoke-generating channel of this invention is set radially from the center of the splash-proof housing 31 to increase, and the opening size of the second smoke-generating channel is set radially from the center of the cover plate 32 to increase. By opening a circular first smoke-generating channel in the middle of the splash-proof housing 31, and setting the opening size of the first smoke-generating channel in five layers radially from the center of the splash-proof housing 31 to increase, and the opening size of the second smoke-generating channel in five layers radially from the center of the cover plate 32 to increase, more uniform smoke dispersion can be achieved, and the oil splashed in the pot 22 can be shielded in multiple layers.

In this embodiment, the bottom of the support portion 311 is placed on the inner surface of the cookware 22, and there is a gap between the support portion 311 and the bottom of the cookware 22. Through the arrangement of the support portion 311 and the smoke-generating portion 312, the support portion 311 is in contact with the cookware 22, and there is a gap between the smoke-generating portion 312 and the cookware 22. After the cookware 22 generates smoke, the support portion 311 guides the smoke, so that the smoke is more concentratedly dispersed to the smoke-generating portion 312, avoiding smoke leakage between the cookware 22 and the splash-proof housing 31.

[0045] Based on the above embodiments, please also refer to...
