[0041] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand this utility model and implement it. However, the embodiments are not intended to limit this utility model. In this embodiment, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this utility model.

[0042] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.

[0043] This embodiment provides an oil fume treatment device, such as... Figures 1 to 2 As shown, the device includes a main housing 100, a filter device 300, and a fan 400. The filter device 300 and the fan 400 are disposed inside the main housing 100. The main housing 100 is provided with an air inlet duct and an air outlet duct, which are connected. The fan 400 drives the airflow to enter from the air inlet duct, which is filtered by the filter device 300, and then discharged from the air outlet of the air outlet duct outside the main housing 100. The air outlet of the air outlet duct is located around the air inlet of the air inlet duct, which is used to form an air curtain around the air inlet of the air inlet duct.

[0044] This utility model provides an air inlet duct and an air outlet duct in the main housing 100. The air inlet duct filter device 300 and the fan 400 are installed inside the main housing 100. The fan 400 drives the airflow to enter from the air inlet duct, and after being filtered by the filter device 300, it is discharged from the air outlet of the air outlet duct outside the main housing 100. Thus, the purified airflow can be discharged into the indoor space, eliminating the need to suck in the fumes and then discharge them outdoors. This eliminates the need for conventional exhaust pipe structures, which are both space-consuming and structurally complex. It enables the fume treatment equipment to be compact and portable, and can effectively address and solve the problem of fumes generated by cooking in indoor spaces outside the kitchen.

[0045] Furthermore, the air outlet of the air outlet duct can form an air curtain around the air inlet of the air inlet duct. The air curtain can prevent some of the oil fumes from escaping before they are drawn into the air inlet of the air inlet duct, which can greatly improve the oil fume treatment capacity and user experience.

[0046] In a preferred embodiment, a fixing bracket 200 is further included. The fixing bracket 200 includes a base 210 and a support rod 220. The base 210 is used to support the main body on a table surface.

In other embodiments, clamping devices can be used to fix the main housing 100 to a board surface, or hanging devices can be used to fix the main housing 100 to a wall surface, or hanging devices can be used to suspend the main housing 100 indoors. The fixing bracket 200 can realize the application scenario requirements of placing the main housing 100 upright on a table, hanging it on a wall, or suspending it indoors. It is understood that the specific form of the fixing bracket 200 will vary depending on the application scenario. Any fixing structure that fixes the main housing 100 in a certain spatial position falls within the scope of the fixing bracket 200 in this embodiment.

[0047] In another preferred embodiment, such as Figures 2 to 5 As shown, it also includes a diversion device 110, which is installed on the main housing 100. The diversion device 110 is connected between the air inlet duct and the air outlet duct. The diversion device 110 is provided with a diversion port 111. Part of the air in the air inlet duct enters the air outlet duct through the diversion device 110, and the other part is discharged from the main housing 100 through the diversion port 111.

[0048] The main housing 100 includes an air inlet housing 120 and an air outlet housing 130. The air inlet housing 120 is provided with a first air outlet 121, and the air outlet housing 130 is provided with a first air inlet 131 at its air inlet end. The first air outlet 121 and the first air inlet 131 are connected by a diversion device 110. The diversion device 110 is provided with a second air outlet 112, which is connected to the first air inlet 131. A baffle 113 is provided between the diversion port 111 and the second air outlet 112 in the diversion device 110. By controlling the specific position of the baffle 113 between the diversion port 111 and the second air outlet 112, the air volume entering the diversion port 111 and the second air outlet 112 can be changed, thereby adjusting the air distribution ratio and optimizing the oil fume treatment efficiency. Furthermore, sound-absorbing cotton or other noise reduction or filtering components are provided between the diversion device 110 and the first air outlet 121 to reduce equipment noise and enhance the filtration effect.

[0049] In a further preferred embodiment, an air curtain assembly is provided at the air outlet end of the air outlet housing 130. The air curtain assembly includes at least one air curtain nozzle 134. One end of the air curtain nozzle 134 is connected to the air outlet end of the air outlet housing 130, and the other end is provided with an air curtain nozzle 135. The air curtain nozzle 135 is the air outlet of the air outlet duct, and the air curtain nozzle 135 is located on any one of the left, right, front, and rear sides of the air inlet of the air inlet duct. Figure 2In the embodiment shown, air curtain nozzles 134 are respectively provided on the left, right and front sides of the air inlet of the air inlet duct. The air curtain generated in this way can surround the area where oil fumes are generated, which can achieve a better smoke collection effect, greatly reduce the possibility of oil fumes escaping before being sucked into the air inlet of the air inlet duct, and significantly improve the oil fume treatment capacity and purification volume.

[0050] Among them, the air curtain nozzle 135 includes, for example, Figure 6 The ventilation holes 136 shown are arranged at intervals in a straight line. The ventilation holes 136 can be circular, elliptical, square, oval, etc.; in other embodiments, such as... Figure 7 As shown, the air curtain nozzle 135 can also be a long strip-shaped ventilation hole 136. That is, the air curtain nozzle 135 can be composed of continuous ventilation holes 136 or discontinuous ventilation holes 136, so that the ejected airflow can form a curtain effect.

[0051] In another preferred embodiment, the air outlet housing 130 is telescopically connected to the air curtain nozzle 134, or the air curtain nozzle 134 has a telescopic structure, so that the distance between the air curtain nozzle 135 and the air inlet of the air inlet duct is adjustable, that is, the position of the air curtain nozzle 135 is adjustable. In practical applications, when facing cooking utensils such as hot pots and induction cookers of different sizes, the size of the oil fume area produced will also be different, so the effective range of the air curtain can be adjusted according to the needs of use, thereby broadening the application range of the oil fume treatment equipment of this utility model.

[0052] Specifically, when Figure 2 As shown, when air curtain nozzles 134 are installed on the left and right sides and the front side of the air inlet of the air inlet duct, the left air curtain nozzle 134 can be extended and adjusted in the direction away from the right air curtain nozzle 134. Similarly, the right air curtain nozzle 134 can be extended and adjusted in the direction away from the left air curtain nozzle 134, and the front air curtain nozzle 134 can be extended and adjusted in the direction away from the air inlet of the air inlet duct.

[0053] The air curtain nozzle 134 sprays filtered air downwards, preferably with the airflow direction set downwards and biased towards the air inlet of the air duct, which can further improve the smoke collection effect. Figure 8 As shown, the front air curtain nozzle 134 is configured to blow air downwards and towards the rear air intake duct, as... Figure 9 As shown, the left air curtain nozzle 134 is configured to blow air downwards and to the right, while the right air curtain nozzle 134 is configured to blow air downwards and to the left. Compared to some current kitchen fume treatment appliances, which are limited by factors such as product size, cookware size, cooking heat, and airflow fluctuations during meals, and suffer from problems such as excessive fume escape and insufficient fume treatment, this embodiment largely avoids the problems of high fume escape rates and insufficient fume treatment, resulting in a significantly improved product experience.

[0054] In another preferred embodiment, the air outlet housing 130 is disposed on top of the air inlet housing 120. This compact arrangement of the air outlet housing 130 and the air inlet housing 120 reduces the material used in their connection structure and the space occupied, which is beneficial for the miniaturization, lightweighting and portability of the device.

[0055] The air inlet housing 120 includes a detachable first housing 123 and a second housing 124. The fan 400 is disposed in the second housing 124. The air inlet housing 120 is divided into a detachable first housing 123 and a second housing 124, which facilitates cleaning of the inside of the air inlet housing 120 and also facilitates the removal of the fan 400 for disassembly, assembly and maintenance.

[0056] The first housing 123 is angled, and a second air inlet 122 is provided on the shell wall located on the inner side of its angle. This allows the air inlets for fume extraction to be placed on two different sides of the space, increasing the area of ​​the air inlets and improving the fume extraction efficiency. Furthermore, since there are usually standing or dining positions during cooking, this design also provides space in front of these positions, better meeting user needs. More preferably, the angle of the first housing 123 includes a first direction and a second direction, with the second air inlet 122 arranged along a third direction, which is perpendicular to the coordinate plane formed by the first and second directions. The first housing 123 has smoke-collecting plates 126 on both sides of the second air inlet 122, parallel to the coordinate plane. The smoke-collecting plates 126 prevent fumes from escaping along the shell wall near the second air inlet 122.

[0057] More preferably, the air outlet housing 130 includes a third housing 132 and a fourth housing 133 that are detachably connected. The third housing 132 is located on top of the first housing 123, and the fourth housing 133 is located on top of the second housing 124. After the first housing 123 is connected to the second housing 124, the third housing 132 is connected to the fourth housing 133, which facilitates the disassembly and maintenance of the air outlet housing 130 during production, assembly, and use.

[0058] In another further preferred embodiment, the air inlet housing 120 further includes a fifth housing 125, which is detachably connected to the second housing 124. The fan 400 includes an exhaust body 410 and a control component. The exhaust body 410 is disposed within the second housing 124, and the control component is disposed in the fifth housing 125.

[0059] In another further preferred embodiment, such as Figure 2 and Figure 10 As shown, the filter device 300 is disposed within the air inlet duct of the first housing 123 or the second housing 124. The filter device 300 includes a filter screen housing 310 and a liquid collection chamber 320. The filter screen housing 310 is filled with a filter body 330. The liquid collection chamber 320 is connected to the filter screen housing 310 and is located at the bottom of the filter body 330, used to collect filtered liquids such as oil and water. The filter screen housing 310 and the liquid collection chamber 320 can be separate structures, connected by a connecting structure, a flow guiding structure, or suspended docking, or they can be... Figure 4 The integrated structure shown; the filter element 330 has functions including condensation and / or adsorption, and can be composed of materials with different filtration functions to better improve the filtration and purification effect on indoor oily air, such as materials that can cool oily fumes to achieve oil-water separation, such as metal wire strips, and porous materials that can adsorb small particles such as smoke and dust.

[0060] It should be noted that, in order to improve the filtration effect, the filter device 300 may also include multiple filter screen housings 310 and corresponding liquid collection chambers 320, or the filter device 300 may be matched and installed at the second air inlet 122, that is, the filter device 300 may be detachably installed at the second air inlet 122.
