In this manner, the purifier 10 is made more intelligent.

When dishes are cooked, the amount of oil smoke caused by different dishes is different, and a user can adjust the oil smoke exhaust force of the range hood 100 according to different dishes, wherein the smaller the wind force is, the less oil smoke particles are mixed in the wind, and the larger the wind force is, the more oil smoke particles are mixed in the wind. When the amount of wind that gets into clarifier 10 is less, when wind speed sensor discerned less amount of wind, can adjust electric component 13's voltage, and then the operating voltage who controls the ion and take place between the subassembly 12 reduces, so, make the ozone volume that the ion takes place the subassembly 12 and produce reduce, when the amount of wind that gets into clarifier 10 is great, when wind speed sensor discerned great amount of wind, can adjust electric component 13's voltage, and then the operating voltage who controls the ion and take place between the subassembly 12 risees, so, make the ozone volume reinforcing that the ion takes place the subassembly 12 and produce. So make clarifier 10 more intelligent and more energy-conserving, clarifier 10 can adjust the ozone volume that the ion that produces produced takes place subassembly 12 along with the amount of wind that gets into clarifier 10, so, can not appear when the amount of wind in clarifier 10 is less, ion takes place subassembly 12 and still produces ozone in a large number, causes the waste of resource.

Specifically, there may be a plurality of gears in the wind speed sensor, different gears correspond to different air volumes, different air volumes correspond to different operating voltages of the ion generating assembly 12, and specific gear settings may be adjusted according to different situations. For example, the shift positions may be 3, 4, 5, or the like. The specific number of gears is not limited herein.

In the present embodiment, the wind pressure switch 16 can control the operation of the ion generating component 12 by the electrical component 13 under the action of the airflow.

Further, the purifier 10 may further include an indicator lamp 17. The indicator light 17 is mounted on the housing 131, and the indicator light 17 is electrically connected to the ion generating assembly 12. When the electrical assembly 13 drives the ion generating assembly 12 into operation, the indicator light 17 is illuminated (either red or green or another colored light) to inform the user that the ion generating assembly 12 is operating. In this way, a user can clearly know whether the ion generating assembly 12 is operating, which is beneficial to the user using the purifier 10.

Referring to fig. 1, the present invention provides a range hood 100, which includes the above-mentioned purifier 10 and a fan 105 connected to the purifier 10. The blower 105 is used for absorbing gas and discharging the gas into the purifier 10, and the second plug 15 of the purifier 10 is connected with the blower 105.

The utility model discloses in smoke ventilator 100's of embodiment clarifier 10, through the setting of ion generation subassembly 12 for clarifier 10 can purify so that the gas from clarifier 10 combustion is cleaner, safe to the oil smoke. By disposing the electrical component 13 outside the housing 11, it is convenient to repair and replace the electrical component 13 when the electrical component 13 is damaged, which is beneficial to repair or replace the purifier 10.

Further, the range hood 100 further includes a casing 101, the casing 101 includes an inlet 102 and an outlet 103, the outlet 103 is in butt joint with the air inlet 1131 of the purifier 10, an air duct 104 is formed in the casing 101, the fan 105 is disposed in the air duct 104, the fan 105 is used for establishing air flow from the inlet 102 to the outlet 103, the fan 105 can suck the oil smoke into the air duct 104 through the inlet 102 in the operation process, and send the oil smoke into the purifier 10 through the outlet 103 and the air inlet 1131 of the purifier 10, the oil smoke is purified in the purifier 10 and then discharged from the purifier 10, and the oil smoke discharged by the purifier 10 is cleaner and safer.

Specifically, the housing 101 may be made of plastic. The plastic is easily available and has high plasticity, thus being beneficial to the mass production of the range hood 100. Of course, the housing 101 may be made of plastic, not only. The material of the housing 101 may be set according to different situations. For example, the housing 101 may be made of stainless steel. The specific material of the housing 101 is not limited herein.

Further, in order to increase the life of the hood 100, a filter may be provided at the outlet 103. The filter screen can filter the oil smoke with larger particles to prevent the oil smoke with larger particles from directly entering the purifier 10 to influence the normal operation of the purifier 10.

Further, the range hood 100 may be disposed above the cooking top 106, and the inlet 102 of the range hood 100 is close to the cooking top 106, so that when a user uses the cooking top 106 to cook, the range hood 100 can absorb objects such as oil smoke, and prevent the objects such as oil smoke from spreading around the cooking top 106, thereby improving user experience.

In some embodiments, the range hood 100 may be integrated with a cooking device such as an induction cooker, a gas range, or the like, and in this case, the range hood 100 may be located below the cooktop 106. The hood 100 may downwardly extract objects such as soot generated during cooking.
