However, it will be understood by those skilled in the art that the following description illustrates preferred embodiments of the utility model by way of example only and that the utility model may be practiced without one or more of these details. Furthermore, some technical features that are known in the art have not been described in detail in order to avoid obscuring the utility model.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the present utility model. It will be apparent that embodiments of the utility model may be practiced without limitation to the specific details that are set forth by those skilled in the art. Preferred embodiments of the present utility model are described in detail below, however, the present utility model may have other embodiments in addition to these detailed descriptions.

The embodiment of the utility model provides a smoke machine. The extractor can be any type of extractor including, but not limited to, a side-draft blower, a top-draft extractor, and the like. Referring in conjunction with fig. 1-3, a smoke machine may include a fan housing 100. A ventilator fan 400 may be disposed within the ventilator housing 100. A fume collecting hood 500 may be connected to the bottom of the fan case 100. The wall of the fan case 100 may be provided with a threading opening 220, and a cable may be threaded into the threading opening 220. The threading opening 220 may be provided on any wall of the blower housing 100. The number of the threading openings 220 may be one or a plurality. The end of the cable within the blower housing 100 may be connected to the blower 400 or may be connected to any other electrical component within the blower housing 100. One end of the cable located outside the fan case 100 may be connected to an electrical component outside the fan case 100, or the cable may be a power cable, and one end of the cable located outside the fan case 100 is directly connected to an external power source. In short, the application is not limited to the use place of the cable and the device to which the cable is connected, and the cable may pass through the threading opening 220.

Referring to fig. 2 and 4 in combination, the extractor hood may also include an oil extractor assembly 300. The oil resistant fan assembly 300 may have an oil resistant air inlet 310 and an oil resistant air outlet 320, the oil resistant air inlet 310 may be in communication with the outside, and the oil resistant air outlet 320 may be located inside the fan case 100 and toward the threading opening 220. The oil resistant fan assembly 300 may suck external wind into the oil resistant fan assembly 300 and blow toward the threading opening 220. The oil resistant blower assembly 300 may be used to create a clean area that covers the threading opening 220. When the smoke ventilator is operated, the smoke ventilator box 100 is internally provided with smoke, and the threading opening 220 can be directly contacted with the smoke ventilator. Thus, the oil smoke can flow to the outer side of the threading opening 220 through the threading opening 220, after a period of use, oil stains can be accumulated on the outer side of the threading opening 220, and when an electric component is arranged at one end of the cable positioned outside the fan box body 100, the oil stains are easy to adhere to the electric component and damage the electric component therein. Further, accumulation of oil stains occurs at the threading opening 220, which is difficult to clean. The arrangement of the oil-proof blower assembly 300 can effectively solve the above-mentioned problems by blowing the external cleaner wind toward the threading opening 220.

The working principle of the oil-proof fan assembly 300 is as follows, and the oil-proof air outlet 320 of the oil-proof fan assembly 300 is arranged towards the threading opening, which can specifically include the following two cases: in case 1, in the illustrated embodiment, the oil-proof air outlet 320 faces the threading opening 220 and the wind flowing out of the oil-proof air outlet 320 does not directly contact the threading opening 220, but increases the flow rate of the wind below the threading opening 220. Thus, the air pressure is reduced under the threading port 220 due to the flow rate, and the air pressure is reduced under the threading port 220 without changing the air pressure above the threading port, that is, an air pressure difference is generated. The air can flow from the higher air pressure to the lower air pressure, so that the upward flow of the smoke at the threading opening 220 can be reduced, and the smoke in the fan box 100 is prevented from flowing out through the threading opening 220. In case 2, the oil-proof air outlet 320 faces the threading opening 220 and the wind flowing out of the oil-proof air outlet 320 directly contacts the threading opening 220. In this way, cleaner external air is directly blown to the threading opening 220, so that the contact between the oil smoke in the fan box 100 and the threading opening 220 is reduced, and the oil smoke is prevented from flowing out through the threading opening 220. Whichever method is used, the oil-proof fan assembly 300 can form a clean area at the threading opening 220 to cover the threading opening 220, and prevent the oil smoke from flowing out through the threading opening 220. By the arrangement, when the electric component is arranged outside the threading opening 220, damage to the electric component in the electric component caused by accumulated oil dirt can be effectively avoided. When the cable is a power line, the arrangement can prevent the greasy dirt in the fan box 100 from flowing out through the threading opening 220, and ensure the cleanliness of the threading opening 220. In addition, the contact between the oil smoke and the threading opening 220 is reduced, so that the cleanliness of the inner side of the threading opening 220 and the cables at the inner side is better.

Illustratively, referring to FIG. 2, the oil and air repellent fan assembly 300 may include an oil and air repellent fan (not shown) and an air guiding structure 340. Wherein, the kind of grease proofing fan is not limited, guarantees that it can blow can. The oil-proof fan may be disposed at an outer side of the fan housing 100, and the oil-proof air inlet 310 may be located on the oil-proof fan. The oil-proof fan can be fixed on the fan box body through the fixing block. The air guiding structure 340 may communicate with a fan outlet (not shown) of the oil resistant fan, and the oil resistant outlet 320 may be located on the air guiding structure 340. External air enters the oil-proof fan through the oil-proof air inlet 310, passes through the air outlet of the fan, passes through the air guide structure 340 and flows out of the oil-proof air outlet 320 to be blown to the threading opening 220. The wind guiding structure 340 can guide wind, so that the setting of the position of the oil-proof fan can be more flexible, and the structural setting is more reasonable. Especially when the oil resistant blower is disposed outside the blower housing 100, the air guiding structure 340 may extend into the blower housing 100. In an embodiment not shown, the oil resistant blower assembly may not be provided with an air guiding structure, and the blower air outlet of the oil resistant blower is directly blown to the threading opening.

1-4, an air guiding structure 340 may be disposed within the blower housing 100. In this way, the oil-proof air outlet 320 located on the air guiding structure 340 may be located in the fan case 100, closer to the threading opening 220, and may better enable the wind to blow toward the threading opening 220. The wind power loss of the oil-proof fan in the process is small, the efficiency is high, and the oil-proof effect is better.

Illustratively, referring to fig. 3 and 4, the air guiding structure 340 includes an air guiding duct. Specifically, one end of the air guide pipe may be fixedly connected to the fan housing 100, and the other end extends toward the threading opening 220. The wind-guiding pipe gathers wind ability better, and the wind direction is more controllable, can make the wind that flows out blow to threading mouth 220 more accurately, and grease proofing effect is better. In an embodiment not shown, the wind guiding structure may be a wind deflector or any other structure that can guide wind.

Illustratively, referring to FIG. 2, the axis (A-B) of the oil outlet 320 is at an angle α to the axis (C-D) of the threading opening 220. Thus, the wind flowing out of the oil-repellent air outlet 320 can be blown toward the threading opening 220 to perform an oil-repellent effect. The angle α between the axis (a-B) of the oil-proof air outlet 320 and the axis (C-D) of the threading opening 220 in fig. 2 is 90 degrees, however, in other embodiments, the angle α may be set according to practical use.

Illustratively, referring to fig. 1, the range hood may further include a housing 210 covering the threading opening 220 and an electrical component (not shown) located within the housing 210, to which a cable is connected through the threading opening 220. The electrical component may be any component of the extractor that involves electrical circuitry, including, but not limited to, a control board for controlling the extractor fan 400, a control board for controlling the air deflector, and the like. The cover 210 may be mounted to any location of the fan case 100. Taking the case where the cover 210 is mounted on the top wall of the fan case 100 as an example, the electric components are located in a space surrounded by the top wall and the cover 210. The enclosure 210 may better protect the electrical components and cables therein. In addition, the oil-proof fan assembly 300 can prevent the oil fume in the fan box 100 from entering the space surrounded by the cover 210 and the box wall, and prevent the accumulated oil dirt from damaging the electric elements. Of course, in some embodiments, the smoke machine may not be provided with a hood, the threading opening may be exposed on the wall of the fan box, and the cable passes through the threading opening.

For example, referring to fig. 4 and 5 in combination, the cover 210 may be provided with a vent hole 211 communicating with the outside. The vent hole 211 may be provided so that the air pressure inside the cover 210 is the same as the air pressure of the external environment. Thus, the air pressure in the cover 210 can be relatively kept stable, and when the oil-proof fan assembly 300 operates, the air pressure difference is generated between the inner side and the outer side of the threading opening 220, so as to ensure the oil-proof effect.

Illustratively, referring to fig. 6, a heat dissipating hole may be provided on the cover 210, and the heat dissipating hole may form the vent hole 211. Therefore, the heat dissipation holes can achieve both heat dissipation effect and ventilation effect, and the structure is simpler. Illustratively, the heat dissipation holes may be plural. For example, the heat dissipation holes may be divided into two rows spaced apart from each other, each row including a plurality of heat dissipation holes to ensure better heat dissipation effect and ventilation effect

Illustratively, the vent 211 may be disposed opposite the threading opening 220. Thus, after the outside air enters the cover 210, the air flows out through the threading opening 220, and the air flow direction is more reasonable. Preferably, the vent hole 211 and the threading opening 220 may be located substantially in the same vertical plane, i.e. the direction of the wind flowing in the housing 210 may be vertically downward, so that the gas flow is more efficient. Of course, in other embodiments, the vent holes may be located on the side wall adjacent the threading opening. For example, the vent holes may be located on the side walls when the threading openings are located on the bottom wall of the housing.

Illustratively, the threading opening 220 and/or the oil resistant blower assembly 300 may be provided at a top wall of the blower housing 100. The space at the top of the smoke machine is better utilized by the arrangement, and the structure arrangement is more reasonable. In other embodiments, the threading opening and/or the oil resistant blower assembly may be located at any other location in the blower housing. For example, the threading opening and/or the oil resistant blower assembly may be provided on the left side wall, right side wall, front side wall, etc. of the blower housing. Preferably, the threading opening 220 and the oil and air resistant fan assembly 300 can be positioned on the same box wall, so that the threading opening and the oil and air resistant fan assembly are close to each other, and the loss of wind power in the wind guiding process is reduced.

Illustratively, the range hood may also include a controller (not shown) and a range hood fan 400. The controller may be electrically connected to the extractor fan 400 and the extractor fan assembly 300. The controller may be used to control the oil and air blower assembly 300 to be turned on in synchronization with the extractor fan 400. Like this, when the cigarette machine fan 400 is opened, the grease proofing fan subassembly 300 opens in order to play grease proofing's effect, and grease proofing is more timely, and the effect is better. The oil-proof fan assembly 300 is not required to be independently operated, and the process is simpler and more convenient. Illustratively, the controller may be mounted within the enclosure 210, controlled by a control board of the range hood. In some embodiments, the control panel may have control keys thereon that individually control the oil and air blower assemblies, and the user may individually control the opening and closing of the oil and air blower assemblies.

Illustratively, the controller may be used to control the oil control fan assembly 300 to turn off after the range fan 400 is turned off for a predetermined period of time. It will be appreciated that after the extractor fan 400 is turned off, the concentration of soot in the air in the fan housing gradually decreases. However, immediately after closing, the oil smoke concentration is still too high, so that the oil and smoke can be prevented from escaping to the outside through the threading opening 220, and the oil and smoke prevention fan assembly 300 can be continuously operated for a preset time period. The predetermined time period may be, for example, 10 minutes. Alternatively, the reserved time period may be set otherwise according to the actual situation.
