Because the brand is too small, the advertising effect is not good, and there is not much splash. Most consumers don't know you at all. No one really cares about the so-called black technology of your product. So they found Xiaomi and they hit it off. On the basis of cleadeep side-suction cigarette cleaner, they launched an upgraded version with Mijia LOGO: Mijia Intelligent Cigarette Cleaner P 1, starting from 3699 yuan, 75% off the original version. The performance is greatly improved: the standard wind pressure is increased from 327Pa to 600Pa, and the maximum static pressure is increased from 444Pa to 900Pa, reaching the mainstream level of high-end DC variable frequency range hood. Facing the high back pressure of public flue during the cooking peak period, the effective air volume of ventilator with large wind pressure is less attenuated and the smoke is smoother. Four words sum up Mijia cigarette cleaner P 1: increase the quantity and reduce the price.
What exactly is a cigarette cleaner? What's the difference with ordinary range hoods? Presumably this problem is everyone's greatest concern. I named a cigarette cleaner in an unconventional way. What is the difference?
First, high performance BLDC motor.
The original cleadeep side-suction smoke eliminator is equipped with a high-speed DC frequency conversion motor with 2300 ~ 3000 rpm. The speed of the motor is about twice that of a traditional cigarette maker. The negative pressure port of the pressure suction range hood is a long and narrow opening, which is obviously different from the negative pressure port of the conventional range hood. With the help of high-speed motor and pressurized suction slot, the highest wind speed at the suction port of hood can reach 13m/s[ 1]. The wind speed is about three times that of the traditional hood. The high-speed airflow creates a low-pressure cyclone above the pot, which limits the disordered oil smoke and prevents it from escaping. Ordinary smoke machine pursues large air volume and uniform negative pressure. The smoke cleaner emphasizes high wind speed and negative pressure concentration. It can be said that the two run counter to each other in the core design concept.
Second, the double wind wheel
Multi-wing centrifugal fan is the core component of range hood. It consists of a motor, a wind wheel and a volute. The wind wheel and volute of a smoke machine are different from ordinary smoke machines. It is a double wind wheel structure, which is equivalent to splicing two wind wheels. There are also two volute tongues (air outlets). High wind speed and double wind wheels form four two-to-two cyclones. This is the core principle of cigarette cleaner. In addition to the "low-pressure four-vortex wind", there are other measures to prevent lampblack from escaping in addition to the range hood.
Third, reverse smoking.
Cleadeep top-suction range hood only has the air outlet against the wall as the negative pressure air outlet, and the other two are the air outlets that generate air curtain. The guide surface of the clean cigarette machine with clean side suction is concave. The above design uses Kangda effect to make the oil fume path lean backwards as far as possible. Mijia cigarette maker canceled the concave guide surface design and returned to the guide surface form of mainstream side suction cigarette maker. However, the side suction hood itself is a back suction type, and whether the guide surface is sunken or not has little effect.
Four, double air curtain smoke prevention.
Double air curtain is another important means for smoke eliminator to prevent oil fume from leaking out. There are independent fans and double exhaust ports at the top of the smoke collection hood, and the air blows downward to form an air curtain. In addition, the left and right sides of the smoke collection hood are provided with coamings, which can also play the role of diversion and smoke blocking.
The above is my interpretation of the technical principle of cleadeep Mijia hood, which should be regarded as the first in the whole network. After all, before hanging the Mijia LOGO, this thing was really unpopular. According to the statement at the press conference, the actual effect of Mijia lampblack purifier in absorbing lampblack and purifying odor is better than the flagship models of big brands. Of course, the specific performance has to be verified by actual measurement. According to the available information, I'll help you summarize the possible highlights and shortcomings. Highlights: four cyclones collect smoke, double air curtain smoke isolation, pressurized tank. Smoking. The feedback of crude oil smoke absorption effect is very good, and the new product has stronger performance and better effect. DC frequency conversion, the maximum static pressure is 900Pa, which solves the problem of difficult smoke exhaust in the peak period of public flue. Disadvantages: high-speed motor, long and narrow air inlet, high gear noise should be not small. Automatic cruise is not supported. Users can only manually adjust the wind speed gear.
Summary: Mijia Intelligent Smoke Remover is made by Cheng Yi Science and Technology, not developed by Xiaomi. Cheng Yi is responsible for "touching people's hearts" and Xiaomi is responsible for the smoke purifier with "price close to the people". Judging from the principle and the actual feedback from users, the effect of absorbing and exhausting lampblack and purifying odor is quite good. The new gas stove is very good. If you are willing to try Mijia range hood, consider starting with P 1 series set. The technology of the range hood itself is not complicated, and the basic principle has not changed for more than ten years. Mijia intelligent range hood P 1 embarks from the basic physical principles, deconstructs the pain points of users' needs, pays more attention to the health problems of chefs, and has embarked on a unique path.
Objectively speaking, Xiaomi's machine technology is very advanced and innovative compared with other domestic range hoods. Due to structural innovation. The motor power is different from that of Shanyou. It is difficult to compare the motor power and distinguish the oil smoke absorption ability between Shang You and Xiaomi. But Xiaomi's machine test shows that the smoking effect is great and worthy of recognition. Xiaomi this machine, I don't know where I saw the physical machine. I don't know if this large order supports return. The name of cigarette cleaner is full of inducement, and there is no mention of purifying cigarettes themselves in the propaganda. The improvement of indoor air quality by exhaust is not unique to his family, and a range hood that can exhaust air can do it. Household needs fart purification, and people's business needs to meet the emission standards of cooking fume pollutants in catering industry.
Of course, the above is only my subjective speculation, there is no experimental basis, or that sentence, waiting for user feedback. Regarding the concept of PM2.5, I have a worry: kitchen fumes are different from floating objects in ordinary spaces and are oily; Generally speaking, PM2.5 sensors are all optical devices. After a long time, oily small particles are very easy to stay or accumulate on the surface of optical devices. At that time, the sensor will be useless. I wonder if the engineer of the manufacturer has considered this problem?
