Background technique

In daily life, we often have to bring water or drinks when we go out. Due to weight or other reasons, the water we bring is bound to be limited, and there is often a situation where there is not enough drinking water.

With the development and progress of society, people's material living standards continue to improve, and the quality of tap water, which is closely related to people's health, has increasingly attracted great attention from the society. However, in recent years, on the one hand, due to the lack of water resources and Environmental pollution has aggravated and water quality has declined. In order to solve this problem, some people have developed various tap water filters and water purification equipment. At present, many water purification equipment are expensive and not easy to clean and replace in time. There are two The hidden dangers of secondary pollution safety cannot meet people's needs very well.

Utility model content

The purpose of the utility model is to overcome the shortcomings of the prior art and provide a portable drinking water filter, which has a simple and unique structure, is more environmentally friendly and is very convenient to use.

In order to achieve the above purpose, a portable drinking water filter provided by the utility model adopts the following technical scheme: it includes a pipe body and a water outlet device, the inner side of the pipe body is provided with a baffle, and the baffle is an annular hollow structure, The hollow structure of the baffle is provided with a filter membrane, and the filter membrane is closely connected with the baffle through a rubber ring. A piston is arranged above the baffle, and a push rod is fixed on the piston. The water outlet device is arranged on The lower part of the tube body. the

Further, the inner wall of the pipe below the baffle is provided with threads, and the outer side of the upper end of the water outlet device is provided with threads, and the water outlet device is tightly connected with the pipe body through the threads on the outer side and the inner wall of the pipe. The lower part of the water outlet device is provided with a water outlet.

The beneficial effects of the utility model are: the filter has a simple and unique structure, is easy to replace, is practical, economical, and is very convenient to carry and use. Drinking water is low in cost, has a large market demand, and can be reused, saving the consumption of plastic bottles, and is more environmentally friendly.

The following is the description of the utility model part symbols and marks:

Pipe body 1, water outlet device 2, baffle plate 3, filter membrane 4, rubber ring 5, piston 6, push rod 7, water outlet 8.

Detailed ways

In order to be able to further understand the features, technical means and achieved specific objectives and functions of the utility model, and to analyze the advantages and spirit of the utility model, a further understanding of the utility model can be obtained through the following detailed description of the utility model in conjunction with the accompanying drawings and specific embodiments .

As shown in the accompanying drawings of the specification, the utility model includes a pipe body 1 and a water outlet device 2. The inside of the pipe body 1 is provided with a baffle 3, and the baffle 3 is an annular hollow structure. A filter membrane 4 is provided, and the filter membrane 4 is tightly connected with the baffle 3 through the rubber ring 5. A piston 6 is arranged above the baffle 3. The piston 6 is fixedly provided with a push rod 7. The water outlet device 2 is provided with At the lower part of the tube body 1. the

The inner wall of the pipe body 1 below the baffle plate 3 is provided with threads, and the outer side of the upper end of the water outlet device 2 is provided with threads, and the water outlet device 2 is tightly connected to the pipe body 1 through the threads on the outside and the threads on the inner wall of the pipe body 1. Connected, the water outlet device 2 is provided with a water outlet 8 at the lower part.

Membrane 4 filtration is a screening process using membrane separation technology. The pressure difference on both sides of the membrane is used as the driving force, and the filter membrane 4 is used as the filter medium. Under a certain pressure, when the raw liquid flows through the surface of the filter membrane 4 , many small micropores densely covered on the surface of the filter membrane 4 only allow water and small molecular substances to pass through to become the permeate, while the substances in the stock solution whose volume is larger than the micropore diameter of the membrane surface are trapped on the liquid inlet side of the membrane and become concentrated liquid. , thus achieving the purpose of purifying, separating and concentrating the stock solution. The filtration accuracy of the filter membrane 4 is 0.001-0.1 microns, and the separation technology of the filter membrane 4 using the pressure difference can filter out harmful substances such as rust, sediment, suspended solids, colloids, bacteria, macromolecular organic matter, etc. in the water, and can retain Some mineral elements that are beneficial to the human body.

In summary, the utility model is an independent two-layer structure, and the two layers are separated by a baffle plate 3 provided with a filter membrane 4. When in use, the water outlet device 2 is first tightened, and the piston 6 is pulled out to fill the water. Put the cup under the water outlet 8, and then press the piston 6 hard to generate pressure, so that the upper layer of water is squeezed from the filter membrane 4 to the lower layer, and the drinking water filtered by the filter membrane 4 can be filled into the cup through the water outlet 8 , ready to drink.

After use, the concentrated residual liquid on the upper layer of the baffle plate 3 can be reused after being washed with water. When the filter membrane 4 is worn out or accidentally damaged, the filter membrane 4 can be taken out for replacement by unscrewing the water outlet device 2 , tighten the water outlet device 2 again, and it can continue to be used.

The above-mentioned embodiments only express some implementations of the present utility model, and the description thereof is relatively specific and detailed, but should not be construed as limiting the scope of the present utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present utility model should be based on the appended claims.
