Recently, "air purifiers" have frequently become media hot words.
On November 6, “352 Environmental Technology†announced that it has obtained the largest financing in the air purifier industry, with a financing amount exceeding RMB 200 million.
On November 7, Hammer Technology held a new product launch conference in Chengdu, Sichuan. In addition to the mobile phone that night, there was also a smart device that was released - a smart air purifier.
On the same day, Philips Air Purifier 2017 media conference was held in Beijing Water Cube. Brand spokesperson Li Chen and many industry guests and media witnessed the launch of Philips' new 5000 series Philips air purifier.
Immediately after the “Double Eleven†National Shopping Festival, Blueair performed well, and sales once again ranked first in the net industry of the United Kong, ranking fourth in the small appliance industry.
At the same time, in the past year, Internet companies such as Jumeiyou, ink weather, and what is worth buying APP have also joined the air purification industry across the border, incorporating air purifier products into the smart home ecosystem.
Looking back at the home appliance circle, Air Clean has become one of the most popular categories today. Almost all well-known home appliance brands have their own empty net products, and the competition tends to become hot. In such a grass-roots era, as long as marketing is done well, many brands can achieve good results. However, the development of the industry looks at opportunities, and the long-term development of the brand depends on products.
Where are the standards for empty net products?
In fact, the threshold of the empty net industry is not so low. Just want to grab the market and rely on OEM production. Enterprises without technical foundation will eventually be short-lived. After all, the air purification industry and the air-conditioning industry belong to the same industry, not the Internet industry. It’s not far from being taken away.
So this also brings us a thought, what is the competition standard of the empty net industry? In the end, what kind of empty net is good?
Starting from a simple and convenient way, we can jump out of the empty net vertical enterprise, and also over the traditional home appliance enterprises, directly against the international manufacturers, from the giants with Samsung's first-class research and development strength to see the trend, to select the full range of use A leading product for demand.
Defining a good empty net product needs to meet some basic requirements, such as the new national standard. The new national standard starts from the following points and comprehensively analyzes the basic advantages of the empty net product: CADR (clean air volume), CCM (cumulative purification amount), energy efficiency rating and noise standard. These four points should affect the purification effect of the air purifier. Core indicators.
It is easy to understand that CADR is how much space can be purified in one hour; CCM can represent the ability to purify pollutants. Only a high CADR does not mean that the air purifier is effective. Only when the CCM is also high can it prove this. The air purifier not only has high purification efficiency, but also has strong purification ability, and the longer the filter life is; the energy efficiency is electricity or not; and the noise index is also very important for the home environment.
From the technical indicators, a good purifier needs to meet high CADR value + high CCM value + high energy efficiency value + low noise.
After more than a year, the new national standard has already had a clear clearing effect on the air purifier market. More and more enterprises and brands have launched empty net products and want to close the new national standard. The performance is not much different.
When everyone is paying attention to the new national standard, whether other standards should also be taken into consideration, such as the “star certification test†designated by the AQSIQ. The certification is carried out by Weikai Certified Testing Co., Ltd. (CVC) according to the "Classification of Filtration Performance of Filter Air Purifiers", from the three items of cumulative purification of particulate matter, energy purification of particulate matter and noise, to Samsung's assessment, and finally to three The sum of the stars of the project is the final star rating for the purification performance of the air purifier.
A trustworthy empty net product, in order to continue to maintain high growth in the future consumer awareness level, in addition to the above foundation, there are more detailed and comprehensive indicators.
"Net Red" products? Maybe not as beautiful as you think!
I think everyone remembers Blueair, a net red product that was hit by the "American Embassy" incident a few years ago. In the past “Double Eleven†National Shopping Festival, sales broke out again and led the net industry.
But in fact, the products of B are really so satisfactory? Take the representative product Blueair 303 as an example:
Appearance, the Blueai303r's body is flat design, all metal, giving a computer chassis feel;
Control, Blueair303 is relatively simple, only a mechanical knob to control the gear position, without any automatic function, there is no PM2.5 detection module inside the machine, just a pure fan plus filter structure.
On the filter screen, Blueair303 does not have the function of filter life reminder. Only one 182-day countdown accessory is delivered separately. This means that Blueair303 completely ignores the external operating environment and running time, but simply chooses to change the filter once every six months. It is neither intelligent nor human at all.
Letter advertising, it is better to believe "effect"
Samsung's blue whirlwind series of explosive products this year, on the basis of meeting the basic requirements of high CADR value, high CCM value, high energy efficiency level and low noise, provides other important indicators for us to purchase an excellent empty net product.
The first is that the purification effect should be clearly visible. Samsung's empty net configuration PM2.5/PM10/smell three independent sensors and display independently, the air quality that is invisible to the naked eye is visually displayed with numerical values ​​and indicators, and PM2.5 is developed according to China's AQI (Air Quality Index) standard. The color of the indicator light corresponding to the PM10 concentration.
Secondly, the filter has a longer life and requires smart tips. Samsung's empty net products are newly added to the electrostatic device, which makes the dust particles charged and more easily adsorbed by the dust collecting filter. It not only has better dust collecting effect, but also is very durable, which can help consumers reduce the cost of using the filter. At the same time, this means that the product's CADR value decays relatively slowly, and it can maintain excellent purification ability for a long time, and the stability is more outstanding.
At the same time, the APP has added a new function of the filter life intelligent reminder, which can judge the remaining life according to the pollution degree of the filter, instead of simply counting down.
The third is intelligent. Samsung's empty net product has WIFI function, which can realize remote intelligent control. Users can grasp the air condition of the home by picking up the mobile phone, and can also achieve rapid purification.
The fourth is that the way of getting out of the wind is more reasonable. Samsung's air-cleaning products use a front air intake and a three-dimensional air outlet. The forward wind design can quickly inhale a large amount of polluted air, and the three-dimensional air outlet design can quickly and evenly deliver the cleaned air to different corners of the room; and the blue cyclone air purifier adopts an ultra-thin design and takes up less space.
The fifth is that the design is more user-friendly. The air purifier is part of the home, and the design is more concise and beautiful, of course, the basic requirements. But on this basis, Samsung's air purifier also takes into account a lot of humanized design. For example, the safety performance, using a small triangle at the air inlet, to avoid the child's finger into the air inlet, the bottom side to the outer surface design, so that the purifier is not easy to be knocked down, the entire body is also integrated streamlined Design, no sharp edges and corners, to ensure that children will not be picked up and so on.
Finally, from this year's double 11 can also see some development trends, such as occupying the empty net category list are high-quality brands; in addition, the consumption upgrade is more obvious, high-quality high-end products, become the mainstream of the market, low-priced explosives disappear It is. But what has not been presented this year is the advantage of product strength. With the improvement of the market and the popularization of user knowledge, the industrial structure will continue to change. For the double 11 market, behind the sales of several hundred million yuan, the real touch of the bones and the far-reaching contest is the contest of product strength. In the future, the main hit High-end, industry-recognized and product-powered brands are expected to continue to leverage and capture more markets.
Triangular prisms are optically transparent bodies with triangular cross-sections. It is an optical instrument with a triangular cross-section made of transparent materials. It is a kind of dispersive prism, which can cause the polychromatic light to be dispersed when passing through the prism.
Light enters from one side of the prism and exits from the other side. The outgoing light will be deflected toward the bottom surface (the third side). The deflection angle is related to the refractive index of the prism, the apex angle and the incident angle of the prism.
White light is a polychromatic light composed of various monochromatic lights. The same medium has different refractive indexes for different colors of light, so the speed of different colors of light propagating in the same medium will be different.
Because the same medium has different refractive indexes for various monochromatic lights, according to the law of refraction, the deflection angle of each monochromatic light will also be different. Therefore, the white light passes through the prism to separate the monochromatic lights, forming seven colors of red, orange, yellow, green, blue, indigo, and purple, that is, dispersion.
