Description

Technical Field

[0001] The utility model relates to the technical field of antibacterial materials, in particular to an antibacterial film with one-way exhaust. Background Art

[0002] Antibacterial film refers to a film with certain antibacterial effects. Usually, the antibacterial film is composed of four layers: silver ion Ag+ antibacterial layer, PET base layer, silicone coating, and release film. The film can inhibit the spread of a variety of bacteria and viruses, so it can be used in food packaging, gift packaging and other fields. Therefore, it is necessary to study it.

[0003] When the antibacterial film is used in specific applications, the membrane can transmit gas from one end of the film to the other end, and use the antibacterial layer inside the film to absorb the bacteria contained in the gas to improve the sterilization and virus inhibition effect of the transmitted gas. However, when the gas circulates, it will move back and forth due to the action of pressure. When the back and forth moving gas passes through the inside of the film, it will drive the film to vibrate, and the vibration of the film can easily cause the film to rupture and damage, which in turn affects the subsequent antibacterial effect of the film. For this reason, we propose an antibacterial film with one-way exhaust. Utility Model Content

[0004] In view of the shortcomings of the existing one-way exhaust antibacterial film, the utility model provides an one-way exhaust antibacterial film, which has the advantages of installing a first external reinforcement film and a second external reinforcement film on the outside of the antibacterial film, and opening an air outlet hole inside the second external reinforcement film. The air outlet hole drives the one-way transmission of the gas. When the gas refluxes, the gas reflux efficiency is reduced through the obstruction of the air outlet hole, thereby improving the filtering effect of the film on the passing gas, thereby solving the problems raised in the above-mentioned background technology.

[0005] The utility model provides the following technical solutions: an antibacterial film with one-way exhaust, comprising a first antibacterial film, a first breathable film and a second breathable film are arranged on both sides of the first antibacterial film, a second antibacterial film and a first external reinforcement film are sequentially installed on one side of the first breathable film, a third antibacterial film and a second external reinforcement film are installed on the side of the second breathable film, a first breathable hole and a second breathable hole are sequentially opened inside the second breathable film, a positioning sleeve is fixedly connected to one side of the first external reinforcement film, and a positioning pin is movably sleeved inside the positioning sleeve.

[0006] Preferably, the first air holes and the second air holes are arranged at equal intervals inside the second air permeable membrane, and the first air holes are in a diamond shape, and the second air holes are in a circular shape.

[0007] Preferably, the second antibacterial film and the third antibacterial film are sequentially arranged outside the first breathable film and the second breathable film, and the first antibacterial film is arranged between the first breathable film and the second breathable film.

[0008] Preferably, the second outer reinforcement film and the first outer reinforcement film are both provided with air outlet holes inside, and the two groups of air outlet holes face the same direction, and the air outlet holes are conical.

[0009] Preferably, a groove is provided inside the positioning sleeve, and one end of the positioning pin is movably sleeved inside the groove, and the positioning sleeve and the positioning pin pass through the second antibacterial film, the first breathable membrane, the first antibacterial film, the second breathable membrane, the third antibacterial film and the second external reinforcement film in sequence.

[0010] Compared with the existing one-way exhaust antibacterial film, the utility model has the following beneficial effects:

[0011] 1. The one-way exhaust antibacterial film is installed between the second antibacterial film, the first antibacterial film and the third antibacterial film through the first breathable film and the second breathable film. At the same time, the first breathable film and the second breathable film are provided with the first breathable hole and the second breathable hole inside to improve the gas flowability of the film. At the same time, the second antibacterial film, the first antibacterial film and the third antibacterial film can filter and absorb bacteria in the passing gas, thereby improving the antibacterial effect of the film.

[0012] 2. The one-way exhaust antibacterial film is installed on the outside of the film through the first outer reinforcement film and the second outer reinforcement film, and the first outer reinforcement film and the second outer reinforcement film are provided with air outlet holes inside. The air outlet holes are conical, and when the gas flows, it can be concentrated and transported to the other end. At the same time, when the gas needs to flow back, the phenomenon of gas reflux can be effectively suppressed. When the bacteria are filtered and accumulated at one end of the second outer reinforcement film, the film can continue to be used by replacing the second outer reinforcement film, thereby increasing the service life of the film.

An outer reinforcement membrane 5 and a second outer reinforcement membrane 7 protect the film. An air outlet hole 8 is opened inside the second outer reinforcement membrane 7. The air outlet hole 8 drives the passing gas to be transmitted in one direction. The first air hole 9 and the second air hole 10 are opened inside the second breathable membrane 3 in sequence. The first air hole 9 and the second air hole 10 improve the gas flowability. A positioning sleeve 11 is fixedly connected to one side of the first outer reinforcement membrane 5. A positioning pin 12 is movably sleeved inside the positioning sleeve 11. The positioning sleeve 11 and the positioning pin 12 assist in reinforcing the antibacterial film.

[0021] See also Figure 4 The first air holes 9 and the second air holes 10 are arranged at equal intervals inside the second air permeable membrane 3. At the same time, the first air holes 9 are in a diamond shape and the second air holes 10 are in a circular shape. The first air holes 9 and the second air holes 10 are arranged at equal intervals inside the second air permeable membrane 3. Then, during the gas circulation process through the first air holes 9 and the second air holes 10, the first air holes 9 and the second air holes 10 can improve the gas circulation efficiency.

[0022] See also Figure 2The second antibacterial film 4 and the third antibacterial film 6 are sequentially arranged outside the first breathable membrane 2 and the second breathable membrane 3, and the first antibacterial film 1 is arranged between the first breathable membrane 2 and the second breathable membrane 3. The second antibacterial film 4 and the third antibacterial film 6 are sequentially arranged outside the first breathable membrane 2 and the second breathable membrane 3, and the first breathable membrane 2 and the second breathable membrane 3 separate the first antibacterial film 1, the second antibacterial film 4 and the third antibacterial film 6. When the first antibacterial film 1, the second antibacterial film 4 and the third antibacterial film 6 are controlled to filter bacteria in the air in turn, they avoid contact with each other to affect the gas flowability.

[0023] See also Figure 2 The second outer reinforcement film 7 and the first outer reinforcement film 5 are both provided with air outlet holes 8, and the two groups of air outlet holes 8 face the same direction and are tapered. The second outer reinforcement film 7 and the first outer reinforcement film 5 are both provided with air outlet holes 8, which are tapered and face one end. The outside of the air outlet holes 8 is tapered. When the gas passes through the air outlet holes 8, the antibacterial film can filter the bacteria. The filtered gas is concentratedly transmitted to the other end through the air outlet holes 8 opened in the first outer reinforcement film 5 and the second outer reinforcement film 7. Since the air outlet holes 8 are tapered, the backflow of gas can be avoided, and the impurities generated by the filtration are accumulated in the second outer reinforcement film 7, which plays a role in improving resource utilization.

[0024] See also Figure 5 A groove is provided inside the positioning sleeve 11, and one end of the positioning pin 12 is movably sleeved inside the groove. The positioning sleeve 11 and the positioning pin 12 pass through the second antibacterial film 4, the first breathable membrane 2, the first antibacterial film 1, the second breathable membrane 3, the third antibacterial film 6 and the second external reinforcement membrane 7 in turn. The first external reinforcement membrane 5, the second antibacterial film 4, the first breathable membrane 2, the first antibacterial film 1, the second breathable membrane 3, the third antibacterial film 6 and the second external reinforcement membrane 7 are installed with the positioning sleeve 11 and the positioning pin 12 on the outside of the first external reinforcement membrane 5 and the second external reinforcement membrane 7. The positioning sleeve 11 and the positioning pin 12 are sleeved and fixed to each other, so that the materials can be fixed and fit more closely.

[0025] Working principle: When in use, the first outer reinforcing film 5, the second antibacterial film 4, the first breathable film 2, the first antibacterial film 1, the second breathable film 3, the third antibacterial film 6 and the second outer reinforcing film 7 are stacked in sequence, and the positioning sleeve 11 and the positioning pin 12 are used to fix the structure, and the first breathable film 2 and the second breathable film 3 are installed on the inner side of the second antibacterial film 4, the first antibacterial film 1 and the third antibacterial film 6, and then in the process of improving gas flowability, the antibacterial effect is provided simultaneously. Since the air outlet 8 is opened on the outside of the second outer reinforcing film 7, the air outlet 8 drives the gas to move in one direction, reducing the problem of gas reflux. At the same time, the second outer reinforcing film 7 collects the filtered bacteria. By replacing the second outer reinforcing film 7, the antibacterial film can continue to be used.
