[0026] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0028] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0029] 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:

[0030] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, this utility model provides a range hood, comprising: a range hood body 1, an oil fume separation mesh 2, a filter mesh 3, an exhaust pipe 4, and a turbine fan 5. The range hood body 1 has a connected air inlet 11 and an air outlet 12. The oil fume separation mesh 2 is located at the air inlet 11. The filter mesh 3 is located inside the range hood body 1, between the air inlet 11 and the air outlet 12, and the mesh density of the filter mesh 3 is less than that of the oil fume separation mesh 2. The exhaust pipe 4 is connected to the range hood body 1, and the air inlet end of the exhaust pipe 4 is connected to the air outlet 12. The turbine fan 5 is located inside the exhaust pipe 4.

[0031] Through the above technical solution, when the range hood is working, the filter screen 3 can filter the oil fumes separated by the oil fume separation screen 2 again, improve the separation and filtration effect of grease in the oil fumes, and avoid the large accumulation of grease on the turbine fan 5, so as to ensure the working performance of the turbine fan 5 and thus ensure that the range hood can achieve a good purification effect.

[0032] In practical applications, the aforementioned filter screen 3 can be made of corrugated aluminum mesh. Aluminum mesh materials (such as pure aluminum plates or aluminum-magnesium alloys) have high-temperature resistance and oxidation resistance, making them suitable for high-temperature oil fume environments requiring long-term operation. Specifically, the corrugated aluminum mesh has a wave height of 50mm and a pore size of 3mm*6mm. This ensures that filter screen 3 can effectively filter the oil fumes separated by the oil fume separator 2, and also ensures that the range hood has sufficient suction power.

[0033] like Figure 3 , Figure 4 and Figure 5 As shown, in some preferred embodiments, the main body 1 of the range hood is provided with a first mounting plate 13 and a second mounting plate 14. The first mounting plate 13 has a mounting groove, and the second mounting plate 14 has a locking hole. One end of the filter screen 3 is located in the mounting groove, and the other end of the filter screen 3 abuts against the second mounting plate 14. The filter screen 3 is provided with a locking block 31 and a pushing block 32. The locking block 31 is connected to the pushing block 32. The locking block 31 extends into the locking hole, and pushing the pushing block 32 can cause the locking block 31 to disengage from the locking hole. Through this technical solution, the filter screen 3 is detachably mounted on the first mounting plate 13 and the second mounting plate 14, which facilitates the user to disassemble and replace the filter screen 3 periodically.

[0034] Specifically, the filter screen 3 has a frame 33 on its edge, and both the locking block 31 and the pushing block 32 are set on the frame 33. One end of the frame 33 is located in the mounting groove, and the other end of the frame 33 abuts against the second mounting plate 14. When the filter screen 3 needs to be removed, a pushing force is applied to the push block 32 from one end of the frame 33 to the other end of the frame 33, causing the push block 32 to move from one end of the frame 33 to the other end of the frame 33. The movement of the push block 32 drives the locking block 31 to move, thereby causing the locking block 31 to disengage from the locking hole and retract into the frame 33. At this time, a pulling force is applied to the filter screen 3 to remove the filter screen 3. When the filter screen 3 needs to be installed in the main body 1 of the range hood, firstly, one end of the frame 33 is inserted into the mounting groove. Secondly, a pushing force is applied to the push block 32 from one end of the frame 33 to the other end of the frame 33, causing the locking block 31 to retract into the frame 33. Then, a pushing force is applied to the filter screen 3, causing the other end of the frame 33 to abut against the second mounting plate 14, and the locking hole to correspond with the locking block 31. Finally, the pushing force on the push block 32 is removed, causing the locking block 31 to protrude from the frame 33 and extend into the locking hole, thus realizing the installation of the filter screen 3. Understandably, after the pushing force on the push block 32 is removed, the push block 32 can use its own gravity to push the locking block 31 out of the frame 33. Of course, an elastic reset component, such as a spring, can also be connected between the push block 32 and the frame 33 so that after the pushing force on the push block 32 is removed, the push block 32 can be reset under the elastic force of the elastic reset component, thereby allowing the locking block 31 to be exposed out of the frame 33.

[0035] like Figure 4and Figure 6 As shown, in some preferred embodiments, the above-mentioned range hood further includes an oil removal component. The oil removal component includes a flow guide 6 and a heating element 7, both of which are disposed within the main body 1 of the range hood. The air outlet end of the flow guide 6 faces the oil fume separation mesh 2, and the heating element 7 is located at the air inlet or air outlet end of the flow guide 6.

[0036] Specifically, the aforementioned air intake component 6 includes an air duct 61, an impeller 62, and a motor 63. The air duct 61 is located inside the main body 1 of the range hood, with its outlet facing the top of the oil fume separation mesh 2. Both the impeller 62 and the motor 63 are located inside the air duct 61, and the impeller 62 is connected to the output end of the motor 63. In practical application, the main body 1 of the range hood is equipped with a control switch electrically connected to the oil removal component. The control switch can control the oil removal component. When the range hood stops working, the oil removal component is activated by the control switch. The motor 63 is energized to drive the impeller 62 to rotate, causing outside air to enter the air duct 61 under the action of the impeller 62. After being heated by the heating element 7, the hot air is blown from the outlet of the air duct 61 towards the oil fume separation mesh 2 under the action of the impeller 62. The grease adsorbed on the oil fume separation mesh 2 flows down along the oil fume separation mesh 2 under the action of the hot air, making the oil fume separation mesh 2 clean.

[0037] Understandably, the degreasing component can either shut down automatically after a predetermined running time or be shut down again via a control switch after starting.

[0038] Specifically, the heating element 7 mentioned above can be a heating wire, a heating tube, or a heating plate.

[0039] In practical applications, the oil fume separation mesh 2 is typically composed of two interlocking mesh plates, forming an oil fume channel between them. To ensure thorough cleaning of the oil fume channel, in some preferred embodiments, the aforementioned guide member 6 is positioned above the oil fume separation mesh 2. The top of the oil fume separation mesh 2 has a first through hole communicating with the oil fume channel inside, with the first through hole facing the air outlet of the guide member 6. This technical solution allows hot air blown from the air outlet of the duct 61 to flow from the top to the bottom of the oil fume separation mesh 2 and enter the oil fume channel through the first through hole. This allows the grease adsorbed on the inner wall (i.e., the inner wall of the mesh plate) and outer wall of the oil fume separation mesh 2 to flow down along the mesh 2 under the action of hot air, resulting in a more thorough cleaning of the oil fume separation mesh 2.

[0040] like Figure 4As shown, in some preferred embodiments, the air inlet 11 is provided with an upper mounting plate 15 and a lower mounting plate 16. The upper mounting plate 15 has a communicating first groove 151 and a second through hole, and the lower mounting plate 16 has a second groove 161. The top end of the oil fume separation net 2 is located in the first groove 151, the first through hole communicates with the first groove 151, and the bottom end of the oil fume separation net 2 is located in the second groove 161. This technical solution not only allows the oil fume separation net 2 to be detachably installed at the air inlet 11 for convenient use, but also does not affect the entry of hot air into the oil fume channel to clean the oil fume adsorbed on the inner wall of the oil fume separation net 2 (i.e., the inner wall of the mesh plate). Specifically, the hot air blown out from the air outlet of the duct 61 enters the oil fume channel sequentially through the second through hole, the first groove 151, and the first through hole.

[0041] It should be noted that when the oil fume separation mesh 2 is installed at the air inlet 11, the bottom end of the oil fume separation mesh 2 abuts against the bottom of the second groove 161, and there is a gap between the top end of the oil fume separation mesh 2 and the bottom of the first groove 151. When the oil fume separation mesh 2 needs to be removed, push the oil fume separation mesh 2 upward so that the top end of the oil fume separation mesh 2 abuts against the bottom of the first groove 151. At this time, the bottom end of the oil fume separation mesh 2 comes out from the second groove 161. Then tilt and push the oil fume separation mesh 2 downward so that the top end of the oil fume separation mesh 2 comes out from the first groove 151, and the oil fume separation mesh 2 can be removed.

[0042] like Figure 4 and Figure 7 As shown, in some preferred embodiments, the bottom end of the oil fume separation mesh 2 has an oil leakage hole that communicates with the second groove 161. The lower mounting plate 16 has an oil drain hole 162 that communicates with the second groove 161. The range hood body 1 is equipped with a detachable oil collecting cup, which is positioned below the oil drain hole 162 when mounted on the range hood body 1. This technical solution allows the grease flowing down the oil fume separation mesh 2 to be collected in the oil collecting cup via the oil leakage hole, the second groove 131, and the oil drain hole 162. Users can periodically remove the oil collecting cup for cleaning, preventing grease from dripping everywhere.

[0043] like Figure 3 and Figure 4 As shown, in some preferred embodiments, the range hood body 1 is provided with an oil receiving plate 17, which is located below the turbine fan 5 installed inside the range hood body 1. An oil drain pipe 171 is formed on the oil receiving plate 17. In specific applications, the oil receiving pipe is connected to an oil receiving cup through a pipe. The oil receiving plate 17 can collect the grease dripping from the turbine fan 5. The grease collected by the oil receiving plate 17 can flow into the oil receiving cup through the oil drain pipe 171 and the pipe to be collected, thus preventing the grease dripping from the turbine fan 5 from accumulating inside the range hood body 1.

[0044] like Figure 1 As shown, in some preferred embodiments, a baffle 8 is hinged to the main body 1 of the range hood, and the baffle 8 movably corresponds to the air inlet 11. In practical applications, the baffle 8 can be opened when the range hood is started, which helps to increase the area for blocking oil fumes, prevent oil fumes from escaping, and thus improve the oil fume extraction rate of the range hood. After the range hood is turned off, the baffle 8 is closed, which helps to reduce the space occupied and also prevents dust, flying insects, etc. from sticking to the oil fume separation net 2 at the air inlet 11, which helps to keep the oil fume separation net 2 clean. Specifically, the baffle 8 can be opened or closed manually or electrically.

[0045] In summary, in one or more embodiments of this utility model, the range hood of this utility model, by setting an oil fume separation mesh at the air inlet of the range hood body and setting a filter mesh between the air inlet and the air outlet inside the range hood body, enables the filter mesh to filter the oil fume separated by the oil fume separation mesh again, thereby improving the separation and filtration effect of grease in the oil fume, avoiding the accumulation of grease on the turbine fan, ensuring the working performance of the turbine fan, and thus ensuring that the range hood can achieve a good purification effect.

[0046] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
