BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to an all-plastic spray device.

2. Description of the Related Art

As a simple and effective solution type liquid output device, micro sprayer is widely used in medical, agricultural, industrial and other daily chemical packaging fields such as hand sanitizer, detergent, shampoos, cosmetics, disinfectants, animal care products, leather polishing, personal care products, furniture polishing products and other fields, which brings people a lot of convenience and quickness. Its working principle is to drive the piston in the pump to move up and down through the reciprocating movement of the head, so that the atmospheric pressure in the pump body is reduced, and the liquid enters the pump body; press the handle down to increase the atmospheric pressure in the pump body, so that the liquid in the bottle is ejected. The sprayer of the prior art relies on a spring located inside the pump body, and the spring is made of metal. When in use, the solution in the bottle will accumulate in the spring position for a long time. Due to the activity of the metal material itself, long-term soaking will cause corrosion. At the same time, the heavy metal content in the composition of the metal spring may exceed the standard. After the metal spring is corroded, it is very easy to cause pollution to the whole package contents, thereby causing harm to the human body. Therefore, the applicant intends to invent an all-plastic spray device that replaces the metal spring with a special environmentally friendly plastic, so that the patented product has a stable structure, reasonable design, good atomization effect, energy saving and environmental protection, long service life, non-toxic and harmless, convenient for overall recycling, and no need to disassemble and classify, which greatly facilitates people's daily use and maintains life, health and safety in people's daily use.

Advantageous Effects

Compared with the prior art, the technical solutions of the invention have the following advantages: the invention adopts the design of two-stage elastic element. Both the environmentally friendly plastic upper spring and the environmentally friendly plastic lower spring are made of plastic materials, which can well replace the metal spring. The two-stage elastic element also has a significant improvement in the pressing feel. In addition to being suitable for conventional liquid use, it is also very suitable for the use of solutions that are prone to corrosion with metal parts. At present, a green, environmentally friendly and low-carbon lifestyle has become the current mainstream. Most sprayers appearing on the market are made of unenvironmentally friendly materials. In the production process of sprayers, the materials used are not environmentally friendly, and a large amount of pollutants and wastewater flow out; pollutants and waste water do not meet the current national regulations, and the difficult-to-degrade pollutants and waste water can cause personal injury, and once caused, it is irreversible, at the same time leads to a serious decline in the service life of the product itself. Therefore, the existing technology has defects, and there is an urgent need in the market for an all-plastic environmentally friendly MINI hand-held micro sprayer to replace the existing product. At the same time, all parts of the patent of the invention are made of environmentally friendly recyclable plastic materials, without any metal materials, which is convenient for overall recycling and does not need to be disassembled and sorted.
