DETAILED DESCRIPTION

[0032] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0033] To facilitate the understanding of the present embodiment, the application scenarios and design ideas of the embodiments of the present application will be briefly introduced below.

[0034] The existing range hood has poor air purification effect, and the user experience is poor.

[0035] Embodiment 1

[0036] The present application provides a range hood, which combines Figure 1 As shown in the figure, the range hood comprises a fan box body 3, an air inlet device 1, and a connection pipeline 2 for connecting the fan box body 3 and the air inlet device 1. The air inlet device 1 is connected to a high-pressure air inlet device 4, and the high-pressure air inlet device 4 generates high-pressure gas which is conducted along the air inlet device 1 and the connection pipeline 2 to the fan box body 3.

[0037] In the present application, since the air inlet device 1 is connected to the high-pressure air inlet device 4, and the air inlet device 1 is also connected to the fan box body 3 through the connection pipeline 2, after the high-pressure air inlet device 4 generates high-pressure gas, the high-pressure gas is sequentially introduced into the fan box body 3 through the air inlet device 1 and the connection pipeline 2 to realize high-pressure air supplement, thereby improving the air purification effect of the range hood and enhancing the user experience.

[0038] Wherein, please refer to Figure 1 In this embodiment, the air inlet 1 is a circular ring with one or two openings and a hollow interior. In fact, the shape of the air inlet 1 can be any shape, such as a rectangular shape, an oval shape, a diamond shape, a flower shape, etc. Different visual effects can be achieved by assembling air inlets 1 of different shapes. Here, only examples are provided and are not limited. The opening of the air inlet 1 is matched with the high-pressure air inlet device 4, and the connection is the air inlet of the air inlet 1. In this way, the high-pressure gas generated by the high-pressure air inlet device 4 enters the air inlet 1 along the air inlet, and then enters the fan box 3 along the air outlet of the air inlet 1 and the connecting pipeline 2.

[0039] In combination with the first aspect, the air inlet 1 has a plurality of air inlets, and adjacent two air inlets are communicated with one high-pressure air inlet device 4.

[0040] Please refer to Figure 2 , Figure 2 An exemplary connection diagram of the air inlet 1 and the high-pressure air inlet device 4 is provided. The air inlet 1 has three air inlets, and each two air inlets are connected with one high-pressure air inlet device 4. That is, the gas generated by one high-pressure air inlet device 4 enters two adjacent air inlets. Compared with the one-to-one correspondence between the high-pressure air inlet device 4 and the air inlet 1, the layout difficulty can be reduced, the occupied space can be reduced, and the cost can be reduced.

[0041] In combination with the first aspect, the high-pressure air inlet device 4 comprises: a supercharger 41, and an airflow passage 42.

[0042] The supercharger 41 is arranged in the device body and is used for compressing air and outputting high-pressure gas along the high-pressure gas outlet 411.

[0043] The airflow passage 42 is arranged on one side of the high-pressure gas outlet, the inlet of the airflow passage 42 is connected with the high-pressure gas outlet 411, and the outlet of the airflow passage 42 is communicated with the air inlet of the air inlet 1.

[0044] Please refer to Figure 3 , the supercharger 41 compresses air and outputs high-speed airflow through the high-pressure gas outlet 411. The high-pressure airflow flows in the airflow passage 42 between the inner wall of the device body and the supercharger 41, and then enters the air inlet 1 through the outlet of the airflow passage 42.

[0045] In combination with the first aspect, the high-pressure air inlet device 4 further comprises a flow regulating member 43, which is arranged in the airflow passage 42 and connected with the high-pressure gas outlet 411.

[0046] In this embodiment, the flow regulating member 43 is provided with dense through holes, and the high-pressure gas is regulated before flowing into the airflow passage 42.

[0047] Please refer toFigure 4 , Figure 4 Another range hood is provided in the present embodiment. The range hood comprises: an air inlet device 1, a connecting pipeline 2, a fan box 3, a high-pressure air inlet device 4, and a mobile air supplement assembly 5.

[0048] The air inlet device 1 is in communication with the fan box 3 through the connecting pipeline 2, and the air inlet device 1 is also in communication with the high-pressure air inlet device 4. The high-pressure air inlet device 4 is used to generate high-pressure gas and introduce it into the air inlet device 1, and the high-pressure air flow is introduced into the fan box 3 along the connecting pipeline 2.

[0049] In the present embodiment, the high-pressure air inlet device 4 is also connected with the mobile air supplement assembly 5, so as to increase the air inlet area and improve the air purification effect. In addition, the mobile air supplement assembly 5 can move relative to the high-pressure air inlet device 4, so as to improve the flexibility of the device and adjust the layout position to purify the air in different areas. It has good capture effect on the front-end smoke escape in particular.

[0050] Specifically, the mobile air supplement assembly 5 has mobility relative to the high-pressure air inlet device 4. This flexibility enables the device to adjust the layout position according to actual needs, so as to concentrate on purifying the air in a specific area as needed. This is very effective for improving local air quality. For example, in a cooking environment, front-end smoke escape is a common problem, and the structure can be flexibly adjusted in position. The mobile air supplement assembly 5 is moved to the target position corresponding to the smoke escape area, and the mobile air supplement assembly 5 is started to significantly increase the air inlet area, so as to suck more air and efficiently capture and purify the escaping smoke in the smoke escape area.

[0051] In order to further improve the intelligent level of the system, the mobile air supplement assembly 5 can be connected with an intelligent control unit. The system can automatically adjust the position and air volume of the air supplement assembly according to the real-time monitoring of air quality data (such as PM2.5, PM10, and other particulate matter concentrations), so as to achieve the optimal air purification effect.

[0052] As shown in Figure 4 The mobile air supplement assembly 5 comprises: a mobile guide rail 51, an air supplement piece 52, and a sliding block 53.

[0053] The mobile guide rail 51 is arranged on the bottom surface of the high-pressure air inlet device 4.

[0054] The air supplement piece 52 is fixedly connected with the sliding block 53, and the sliding block 53 is in sliding cooperation with the mobile guide rail 51 to drive the air supplement piece 52 to move along the extension direction of the mobile guide rail 51.

[0055] In combination with the first aspect, a driving assembly (not shown in the figure) is further included, which is connected with the sliding block 53 and used to drive the sliding block 53 to move along the mobile guide rail 51.

[0056] It can be understood that the driving assembly provides a power source to generate driving force to drive the sliding block 53 to move. The driving mode of the driving assembly can be electric driving, pneumatic driving, etc. without limitation, as long as the driving force can be generated to drive the sliding block 53 to move.

[0057] It can be understood that the supercharger 41, the fan, etc. in the high-pressure air inlet device 4 also need to be connected to a motor to drive the supercharger 41 to operate. This is a more conventional technical means, which will not be repeated here.

[0058] In combination with the first aspect, the fan box 3, the connecting pipeline 2, and the air inlet device 1 are arranged indoors.

[0059] The fan box 3, the connecting pipeline 2, and the air inlet device 1 are arranged indoors to capture and purify the oil fume in the kitchen area. In this process, the operation of the fan in the fan box 3 will generate a certain noise.

[0060] In combination with the first aspect, the fan box 3 is arranged outdoors, and the fan box 3 is connected with the connecting pipeline 2 and the air inlet device 1 in sequence through the extension pipeline 6 extending to the indoor.

[0061] Please refer to Figure 5 The fan is arranged outside to reduce the influence of the noise generated during the operation of the fan on the user in the kitchen environment and improve the user experience.

[0062] In the second aspect, the application provides an oil fume extractor control system, which comprises the oil fume extractor described above.

[0063] The oil fume extractor described above can be assembled and used to achieve efficient fume purification effect, thereby improving the user experience.
