[0028] The following is a detailed description of the aseptic compressed air filtration mechanism for packaged drinking water production according to an embodiment of the utility model in conjunction with the accompanying drawings.

[0029] Example 1

[0030] For easier understanding, see Figures 1 to 4 , an embodiment of the aseptic compressed air filtration mechanism for packaged drinking water production provided by the utility model comprises a circulation pipe 1, a filtration mechanism is arranged inside the circulation pipe 1, and a steam sterilization mechanism is arranged inside the circulation pipe 1;

[0031] The steam sterilization mechanism includes a water tank 3, a mounting tube 4, a heating wire 10, a guide 12 and a hydrophobic breathable membrane 19. The water tank 3 is fixedly mounted on the side wall of the circulation tube 1, the heating wire 10 is fixedly mounted inside the water tank 3, the mounting tube 4 is fixedly mounted on the top of the water tank 3, and the mounting tube 4 is connected to the water tank 3, one end of the mounting tube 4 extends to the inside of the circulation tube 1, the guide 12 is fixedly mounted on the side wall of the mounting tube 4, the guide 12 is located inside the circulation tube 1, an air inlet 13 connected to the mounting tube 4 is provided inside the guide 12, an air outlet 14 corresponding to the air inlet 13 is installed at the bottom of the mounting tube 4, the hydrophobic breathable membrane 19 is installed inside the circulation tube 1, and a connecting groove 21 connected to the water tank 3 is provided inside the circulation tube 1.

[0032] It should be noted that one end of the circulation pipe 1 is connected to the compressor, and the other end of the circulation pipe 1 is connected to the connection end of the drinking water production equipment, so that the compressed air generated by the compressor can be transported to the drinking water production equipment through the circulation pipe 1. The water storage tank 3 is filled with water, and the internal water source is heated by the heating wire 10 inside the water storage tank 3, so that high-temperature water vapor is generated inside the water storage tank 3 and flows into the installation pipe 4. When the compressed air passes through the circulation pipe 1, it will pass through the installation pipe 4 inside the circulation pipe 1, and the compressed air enters from the air inlet 13 at the top of the installation pipe 4 and then flows out from the air outlet 14. During the process, the compressed air will come into contact with the high-temperature water vapor inside the installation tube 4, and the high-temperature water vapor can be used to sterilize the compressed air. After that, the compressed air with water vapor will come into contact with the hydrophobic breathable membrane 19 at the bottom of the installation tube 4. When the compressed air with water vapor passes through the hydrophobic breathable membrane 19, the liquid in the compressed air will be filtered and retained on the top of the hydrophobic breathable membrane 19. This part of the liquid then flows into the water storage tank 3 through the connecting groove 21 and is heated to generate high-temperature water vapor, so as to disinfect and sterilize the compressed air, ensure the cleanliness of the compressed air, and avoid affecting the quality of drinking water.

[0033] In some embodiments, the hydrophobic breathable membrane 19 is located at the bottom of the installation tube 4, the connecting groove 21 is located between the top of the hydrophobic breathable membrane 19 and the bottom of the installation tube 4, and the hydrophobic breathable membrane 19 is installed obliquely.

[0034] In some embodiments, a filter element 22 is fixedly installed inside the communicating groove 21 , the air inlet 13 and the air outlet 14 are both conical openings, and the guide element 12 is an arc-shaped element.

[0035] It should be noted that by arranging a filter element 22 inside the connecting groove 21, the liquid passing through the connecting groove 21 can be filtered, and by making the air inlet 13 and the air outlet 14 both conical openings and setting the guide element 12 as an arc-shaped element, the air inside the circulation tube 1 can flow through the mounting tube 4 faster.

[0036] In some embodiments, a slide groove 15 is opened on the inner wall of the circulation tube 1, a guide rail 17 is fixedly installed inside the slide groove 15, a slider 16 is slidably connected to the side wall of the guide rail 17, a support spring is fixedly installed between one side of the slider 16 and the inner wall of the slide groove 15, and the support spring is located on the side wall of the guide rail 17.

[0037] It should be noted that one end of the hydrophobic breathable membrane 19 is connected to the slider 16, and the slider 16 can be supported by setting a support spring. By connecting one end of the hydrophobic breathable membrane 19 to the slider 16, when the air flows inside the circulation tube 1, the hydrophobic breathable membrane 19 can be driven to shake, so that the liquid on the surface of the hydrophobic breathable membrane 19 can flow into the connecting groove 21 faster.

[0038] Example 2

[0039] In some embodiments, Figure 1 , Figure 2 As shown, the filtering mechanism includes a mounting member 2, a water-removing and oil-removing filter screen 5, a foreign matter-removing filter screen 6, an activated carbon deodorizing filter screen 7, a pre-filter screen 8 and a sterilizing filter screen 9. The mounting member 2 is fixedly mounted on the side wall of the circulation pipe 1, and the circulation pipe 1 is connected to the mounting member 2. The water-removing and oil-removing filter screen 5 is mounted inside the mounting member 2, and the foreign matter-removing filter screen 6, the activated carbon deodorizing filter screen 7, the pre-filter screen 8 and the sterilizing filter screen 9 are all fixedly mounted inside the circulation pipe 1. A transverse U-shaped groove is opened inside the circulation pipe 1 at the mounting member 2, and the U-shaped groove is located inside the mounting member 2.

[0040] It should be noted that by setting up a water-removal and oil-removal filter 5, the compressed air flowing through can be filtered for water and oil removal, by setting up a foreign matter removal filter 6, the compressed air flowing through can be filtered for foreign matter removal, by setting up an activated carbon deodorization filter 7, the odor in the compressed air can be filtered, by setting up a pre-filter 8, the compressed air can be pre-filtered, and finally, by using a sterilization filter 9, the compressed air can be further sterilized and filtered, thereby further increasing the cleanliness of the compressed air.

[0041] In this example, a heat conductor 11 is fixedly installed inside the water tank 3 and is located on top of the heating wire 10. The heat conductor 11 can prevent the heating wire 10 from directly contacting the water source inside the water tank 3, thereby avoiding leakage.

[0042] In this example, the filter screens inside the circulation pipe 1 are, from top to bottom, a water and oil removal filter screen 5, an impurity removal filter screen 6, an activated carbon deodorization filter screen 7, a pre-filter screen 8 and a sterilization filter screen 9.

[0043] In this example, a filling port can be installed on one side of the water storage tank 3.

[0044] Working principle: When the compressed air passes through the inside of the circulation pipe 1, it will flow through the U-shaped groove to the water and oil removal filter 5 for water and oil removal filtration, and then pass through the impurity removal filter 6 and the activated carbon deodorization filter 7 for impurity and deodorization filtration. When passing through the installation pipe 4 inside the circulation pipe 1, the compressed air enters from the air inlet 13 at the top of the installation pipe 4 and then flows out from the air outlet 14. In this process, the compressed air will come into contact with the high-temperature water vapor inside the installation pipe 4, and the high-temperature water vapor can be used to sterilize the compressed air at high temperature. After that, the compressed air with water vapor will come into contact with the hydrophobic breathable membrane 19 at the bottom of the installation pipe 4. When the compressed air with water vapor passes through the hydrophobic breathable membrane 19, the liquid in the compressed air will be filtered and retained on the top of the hydrophobic breathable membrane 19, and then pass through the pre-filter 8 and the sterilization filter 9 for the final sterilization filtration, thereby ensuring the cleanliness of the compressed air.

[0045] According to the above embodiment, in the production of new drinking water, the first air bag is used as the bottom layer, the second air bag is used as the middle layer, and the third air bag is used as the top layer. Among them, the top layer is a small-area air bag, which contacts the human body and increases the massage intensity; the bottom layer and the middle layer are large-area air bags, which can increase the height and the effect of the massage is the distance; the middle layer can stabilize the top layer and prevent the small air bags on the top layer from tilting; the top layer air bag is a small-area square or round air bag, which has little contact with the massaged part, has a large effect intensity, and greatly enhances the massage effect.

[0046] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
