Description

Technical Field

[0001] The present invention relates to the technical field of light wave irradiation, and particularly to a water filter device and an infrared physiotherapy instrument. Background Art

[0002] Near-infrared physiotherapy devices mainly utilize the thermal effect of infrared light. By emitting near-infrared light of a specific wavelength, the near-infrared physiotherapy device can penetrate the skin and directly cause thermal effects in muscles, subcutaneous tissues, etc., accelerating the removal of waste and transporting nutrients, strengthening the metabolism of local tissue cells, reducing pain, increasing muscle relaxation, and producing a massage effect. Existing near-infrared physiotherapy devices generally filter far-infrared light in the light source through a light wave irradiated water filter. However, the liquid in the existing light wave irradiated water filter is mainly water, which has many deficiencies in terms of stability, boiling point index, thermal conductivity, etc. When the near-infrared physiotherapy device works for a long time, the temperature of the liquid in the light wave irradiated water filter is likely to rise and expand, causing a large pressure inside the light wave irradiated water filter, resulting in the liquid being easily leaked and even exploding.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0029] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. of the present invention is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and should not be construed as indicating or implying relative importance.

[0030] As Figures 1-5 shown, a water filter device of a preferred embodiment of the present invention includes a mounting ring 1, a first glass 2 and a second glass 3 disposed in the inner hole of the mounting ring 1. A solution chamber 4 is formed between the first glass 2 and the second glass 3. The solution chamber 4 is filled with a transparent solution. The transparent solution includes the following components by weight percentage: ethylene glycol 30%-40%, heat conductive agent 3%, dispersant 1%, antibacterial agent 0.1%, defoaming agent 0.1%, and the balance is high-purity water, that is, the weight percentage of high-purity water is 55.8%-65.8%. Among them, the high-purity water is water with a resistivity higher than 18.2 MΩ*cm. As the main solvent, the high-purity water has good solubility, can quickly disperse other components, and at the same time adjusts the concentration of the solution to an appropriate range to ensure that all components are fully dissolved to form a homogeneous transparent system, which is convenient for the preparation of this transparent solution; ethylene glycol can be uniformly mixed with high-purity water and is not easily layered. Ethylene glycol enables this transparent solution to have the characteristics of high boiling point and high transmittance (transmittance of near-infrared); the heat conductive agent enables this transparent solution to have the characteristic of high thermal conductivity, and can quickly transfer the heat of this transparent solution to other components for heat dissipation; the dispersant can reduce the surface tension of the liquid, make the particles easier to disperse in the liquid, and prevent the particles from agglomerating with each other, thereby promoting the mixing of materials; the antibacterial agent can effectively inhibit the growth of various microorganisms in the solution; the defoaming agent can effectively inhibit the generation of foam during the production and use of the solution, ensure the transparency of the solution, and deionized water is used to adjust the concentration of the solution to an appropriate range to ensure that all components are fully dissolved to form a homogeneous transparent system.

[0031] The working principle of this embodiment is as follows: The solution chamber 4 of the water filter device 100 is filled with a transparent solution, which is prepared from high-purity water, ethylene glycol, a heat-conducting agent, a dispersant, an antibacterial agent, an antifoaming agent, and deionized water. Thus, it has the characteristics of high boiling point and high selective transmittance, can well achieve filtering (filtering of far-infrared light), and is not prone to boiling and expansion after absorbing heat during filtering, which helps the long-term use of the water filter. At the same time, this transparent solution also has good heat-conducting performance, which helps its heat dissipation and further prevents it from boiling. In addition, this transparent solution also has the functions of antibacterial and preventing bubble generation, ensuring the transparency of the solution to ensure the filtering function of the water filter.

[0032] Exemplarily, the heat-conducting agent is nano-aluminum oxide, which has a high thermal conductivity, a low coefficient of thermal expansion, and excellent thermal stability.

[0033] Exemplarily, the dispersant is water-soluble aluminum oxide, which can effectively disperse nano materials (such as aluminum oxide, zirconium oxide, barium titanate, etc.) uniformly in the aqueous system, prevent particle aggregation, and can provide the stability of the dispersion system to ensure that the nano materials remain uniformly dispersed in the liquid without deposition.

[0034] Exemplarily, the antibacterial agent is a Kathon preservative, which has the characteristics of antibacterial, bacteriostatic, antiseptic, low toxicity and low irritation, environmental protection and no residue, and good stability.

[0035] Exemplarily, the antifoaming agent is a silicone antifoaming agent, which has strong defoaming ability and good thermal stability.

[0036] Meanwhile, the present invention provides a preparation method of the transparent solution, including the following steps:

[0037] S1: Weigh high-purity water, ethylene glycol, a heat-conducting agent, and a dispersant according to the ratio, and put the weighed ethylene glycol, heat-conducting agent, dispersant, and part of the high-purity water into a constant-temperature stirring reaction kettle. The amount of high-purity water added is the same as that of ethylene glycol. The purpose of adding high-purity water in two portions is to prevent excessive heat release during dilution of the solution system in industrial mass production.

[0038] S2: Control the constant-temperature stirring reaction kettle at 20°C - 30°C and stir at a speed of 300 revolutions per minute for 15 minutes to make the various materials preliminarily mixed evenly.

[0039] S3: Add the antibacterial agent, antifoaming agent, and the remaining part of the high-purity water into the constant-temperature stirring reaction kettle according to the ratio, control the constant-temperature stirring reaction kettle at 35°C - 40°C, and stir at a speed of 800 revolutions per minute for 5 minutes to make the various materials fully mixed evenly.

[0040] S4: Place the solution in an ice bath (to prevent the solution from heating up violently during sonication, which may cause volatilization and secondary aggregation of nanoparticles), and then sonicate it at 30 KHZ for 10 - 15 minutes to ensure that all components are completely dissolved and the solution is free of visible particles and turbidity.

[0041] S5: Use a vacuum pump to evacuate the solution for 15 - 20 minutes to reduce the solubility of gases in the solution, extend the shelf life of the solution, and prevent the formation of bubbles during use.

[0042] S6: After filtering through a 0.22 - micron filter, fill and seal to ensure the transparency of this clear solution.

[0043] The following is an example of preparing 100 g of this clear solution. First, weigh 30 g of high - purity water, 30 g of ethylene glycol, 3 g of a heat - conducting agent (nano - heat - conducting alumina), and 1 g of a dispersant (water - soluble alumina dispersant), and put them into a constant - temperature stirring reaction kettle. Then set the initial temperature at 25°C and stir at 300 revolutions per minute for 15 minutes. Subsequently, add 0.1 g of an antibacterial agent (Carlin preservative) and 0.1 g of an antifoaming agent (silicone antifoaming agent) into the constant - temperature reaction kettle, and slowly inject 35.8 g of high - purity water. Raise the temperature of the constant - temperature stirring reaction kettle to 40°C and stir at a speed of 800 revolutions per minute for 5 minutes. Then place the solution in an ice bath and sonicate it at 30 KHZ for 15 minutes. Finally, filter it through a 0.22 - micron filter membrane and seal it in a brown glass bottle.

[0044] The transmittance of the obtained clear solution was measured and compared with that of pure water. The results are as Figure 6 shown. It can be seen that compared with pure water, this clear solution has a higher transmittance for near - infrared light.

[0045] In addition, an accelerated aging test was carried out on the obtained clear solution for 7 days. The results showed no precipitation or turbidity, the performance met the standards, it met the expected applications, and had characteristics such as high infrared transmittance, the solvent was not easily deteriorated under high temperature and high pressure, and had good flow and heat - conducting properties.

[0046] Exemplarily, the water filter device 100 further includes a circulation pipeline 5. An input port 11 and an output port 12 that are respectively communicated with the solution chamber 4 are provided on the mounting ring 1. The input port 11 is connected to the output port 12 through the circulation pipeline 5. That is, the transparent solution in the solution chamber 4 can be transported to the circulation pipeline 5 through the output port 12, and then return to the solution chamber 4 through the input port 11. A heat dissipation pipe 51 and a pumping pump 52 are provided on the circulation pipeline 5. In this embodiment, the output port 12 is connected to the input end of the pumping pump 52, the output end of the pumping pump 52 is connected to one end of the heat dissipation pipe 51, and the other end of the heat dissipation pipe 51 is connected to the input port 11. Under the action of the pumping pump 52, the transparent solution in the solution chamber 4 will be transported into the heat dissipation pipe 51. It can be understood that the heat dissipation pipe 51 has good heat dissipation performance, which helps to dissipate heat and cool down the transparent solution therein. Subsequently, the transparent solution in the heat dissipation pipe 51 returns to the solution chamber 4, that is, the transparent solution circulates, which helps to keep the transparent solution in the solution chamber 4 at a relatively low temperature and prevent it from boiling and expanding. And the defoaming agent in this transparent solution can effectively prevent bubbles from being generated when the transparent solution circulates, thereby ensuring the transparency of the solution and ensuring the normal use of the water filter device 100.

[0047] Exemplarily, the water filter device 100 further includes a plurality of heat dissipation fins 6. The heat dissipation pipe 51 is arranged through a plurality of heat dissipation fins 6. Generally, the heat dissipation pipe 51 is arranged in an S-shaped circuitous manner, which helps to increase the contact area between the heat dissipation pipe 51 and the heat dissipation fins 6. The heat of the heat dissipation pipe 51 will be transferred to the heat dissipation fins 6, which helps to improve the heat dissipation efficiency of the heat dissipation pipe 51.

[0048] Exemplarily, the water filter device 100 further includes a heat dissipation fan 7. The blowing end of the heat dissipation fan 7 faces a plurality of heat dissipation fins 6, which improves the fluidity of the air flow at the heat dissipation fins 6, thereby improving the heat dissipation efficiency of the heat dissipation fins 6, that is, indirectly improving the heat dissipation efficiency of the heat dissipation pipe 51.

[0049] At the same time, as Figures 1-5 shown, the present invention also provides an infrared physiotherapy device, which includes a housing 200, an infrared light source 300, and the above-mentioned water filter device 100. The water filter device 100 is installed at the front end of the housing 200, and the infrared light source 300 is installed in the housing 200 and faces the water filter device 100. When in use, the light emitted by the infrared light source 300 passes through the first glass 2, the transparent solution in the solution chamber 4, and the second glass 3 and then exits, thereby realizing filtering. The transparent solution in the water filter device 100 has high transparency and characteristics such as high transmittance, high thermal conductivity, and high boiling point, which helps the long-term use of this infrared physiotherapy device.

[0050] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
