Application of vacuum pump
Vacuum pumps are increasingly being used in cosmetic products, especially in the area of skin care. Although consumers may not know what a vacuum pump is, for them, they can feel the convenience of product use.
The vacuum pump has the following advantages with its unique design features:
1. The content is not in contact with the air. This is one of the biggest advantages of vacuum pump products. Because the content product does not touch the air, it can avoid the oxidation of the product, on the other hand, the product also adds less preservatives.
2. As a result of the vacuum pump bottles using the scraper type piston design, the product of the retention rate is lower, generally below 5%, the price is more expensive products, such as the essence, eye cream, there is no doubt that you will get less waste from this. Especially when choose transparent bottles, bottles of the vacuum flask wall in use process always stay cleaner, and selection of emulsion pump with straw, usually due to products with bottle wall and the look is not very beautiful.
3. It can be used without the restriction of Angle. The vacuum pump can be used in 360 degrees, which can be used in many applications, such as in the American market, and has been used in collar cleaning products.
However, the vacuum pump is also restricted by the design of piston technology, which restricts the design limitation of the shape of the bottle, which is generally round or oval. More and more products are being designed to break through this limitation.
There is no big difference between the vacuum pump and the general emulsion pump in the pump body. In other words, the general emulsion pump can be converted into a vacuum bottle in theory. Vacuum pump is difficult with the sealing performance of each part, because the required air tightness is extremely high, so the mold, spare parts requirement is high, otherwise, it is easy to occur the material body pump don't come out.
The design of the vacuum flask, besides fluctuation full time is various in shape, function and beautiful appearance sets a suit, on the design of the pump body, many companies are also seeking a more simple and environmental design. The common quantitative pump body generally needs these components: spring, seal valve (or seal ball), piston, pump body shell (size determines each pump output). Now, the design trend of pump body is to replace the functions of these conventional parts with more and more simple and integrated design, so as to realize less material and the same function. Instead of the metal spring function is an important step, because the metal spring recovery of carbon emissions is higher, at the same time, in some sensitive material in the body, metal spring is easy to rust, seriously affect the quality of the products.
Domestic manufacturers in the vacuum pump field is still in the preliminary stage, the current technology is still controlled by several major manufacturers abroad. Its main reason is the vacuum pump on the accuracy of product size requirement is very high, slightly different, can lead to bad sealing and pump products not to come out, the next thing you can imagine, consumer complaints, lost market share.
Another trend of the vacuum pump is to apply the vacuum pump technology to the home cosmetic instrument. In a nutshell, vacuum pump more and more get the favour of various departments, including marketing and packaging engineer, because it not only integrates the supply chain (supplier), and indeed on functional is superior to conventional emulsion pump, in terms of decoration, basically not much difference with general emulsion pump vacuum pump. Vacuum pump technology in new market will also have more and more applications.
