[0009] The specific embodiments of this invention will be described in more detail below with reference to the schematic diagrams. The advantages and features of this invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this invention.

[0010] Figure 1 This diagram shows a flowchart of a surface treatment method provided according to an embodiment of the present invention. This surface treatment method is applicable to materials suitable for anodizing, such as aluminum, aluminum alloys, titanium, and titanium alloys. Aluminum refers to pure aluminum, and aluminum alloys refer to mixtures based on aluminum with the addition of other alloying elements. Similarly, titanium refers to pure titanium, and titanium alloys refer to mixtures based on titanium with the addition of other alloying elements.

[0011] As shown in the figure, the surface treatment method of this embodiment includes the following steps.

[0012] First, as described in step S110, a housing is provided. This housing may be made of aluminum, aluminum alloy, titanium, or titanium alloy.

[0013] Subsequently, as described in step S120, a liquid is prepared. In one embodiment, the main component of this liquid is water, and the liquid contains at least one mosquito-repellent ingredient.

[0014] In one embodiment, the mosquito-repellent ingredient in the liquid may include natural mosquito-repellent ingredients such as ethyl butylacetaminopropionate (InsectRepellent 3535, IR3535), p-menthane-3,8-diol (PMD), citronellol, limonol, and eucalyptus. In one embodiment, if the total volume of the liquid is 1000 mL, the aforementioned mosquito-repellent ingredients may be in the following quantities: 25 g of ethyl butylacetaminopropionate, 10 g of p-menthane-3,8-diol, 3 g of citronellol, 5 g of limonol, and 1 g of eucalyptus.

[0015] Next, as described in step S130, the casing is anodized to create micropores on its surface. In one embodiment, step S130 may use a sulfuric acid anolyte to anodize the casing.

[0016] Anodizing is a surface treatment technique that uses an electrochemical method to treat a workpiece (metal or alloy) as the anode, subjecting it to electrolytic oxidation to form a dense oxide layer on the workpiece surface. In this embodiment, the workpiece referred to in the preceding text is the shell. Furthermore, for workpieces made of aluminum, aluminum alloys, titanium, or titanium alloys, anodizing will result in a porous oxide layer on the workpiece surface, creating numerous micropores.

[0017] In one embodiment, the anodizing step S130 generates micropores with a size between 20 and 40 nanometers on the surface of the housing to ensure that liquid can effectively penetrate into the micropores in subsequent steps, and also to ensure that the sealing step can effectively prevent liquid from leaking out of the micropores.

[0018] Then, as described in step S140, the shell is immersed in the liquid to ensure that the liquid can fully penetrate into the micropores.

[0019] Finally, as described in step S150, the shell is sealed to prevent leakage of the liquid filled in the micropores. In one embodiment, the shell is sealed by immersion in hot water at 90 to 100 degrees Celsius. However, this invention is not limited to this; other sealing methods, such as nickel salt method, steam method, chromic acid method, etc., can also be applied to this invention.

[0020] Please refer to the above as well. Figure 2 The above, Figure 2 show Figure 1 An embodiment of step S140 in the process.

[0021] As shown in the figure, first, as described in step S210, a soaking tank is prepared and the liquid is placed into the soaking tank.

[0022] Then, as described in step S220, place the shell into the soaking tank and maintain the liquid temperature between 20 and 30 degrees Celsius. The soaking time is approximately 15-40 minutes.

[0023] This avoids the situation where the pores are sealed due to excessively high immersion liquid temperature, and ensures that the liquid (especially the mosquito-repellent ingredients in the liquid) effectively fills the micropores created by the anodizing process.

[0024] Figure 3 This diagram shows a flowchart of a surface treatment method provided according to another embodiment of the present invention.

[0025] As shown in the figure, the surface treatment method of this embodiment includes the following steps.

[0026] First, as described in step S310, a housing is provided. This housing may be made of aluminum, aluminum alloy, titanium, or titanium alloy.

[0027] Subsequently, as described in step S320, a liquid is prepared. This liquid contains at least one mosquito-repellent ingredient and one dyeing ingredient.

[0028] In one embodiment, the mosquito-repellent ingredient in the liquid may include natural mosquito-repellent ingredients such as ethyl butylacetaminopropionate, p-menthane-3,8-diol, citronellol, limonol, and eucalyptus. In another embodiment, the aforementioned dyeing ingredient is selected from the group consisting of natural dyes such as indigo, safflower, turmeric, and gardenia.

[0029] Next, as described in step S330, the housing is anodized to create micropores on its surface.

[0030] Then, as described in step S340, the shell is immersed in the liquid to ensure that the liquid can fully penetrate into the micropores. In one embodiment, the immersion time of the shell is approximately 15-40 minutes to ensure that the shell is fully dyed.

[0031] Finally, as described in step S350, the shell is sealed to prevent leakage of the liquid filled in the micropores. In one embodiment, the shell is sealed by immersion in hot water at 90 to 100 degrees Celsius. However, this invention is not limited to this; other sealing methods, such as nickel salt method, steam method, chromic acid method, etc., can also be applied to this invention.

[0032] In another embodiment, the sealed shell may be further baked. The baking temperature is 65-75 degrees Celsius, and the baking time is 30-45 minutes. This baking step ensures that the moisture adhering to the shell surface during the previous sealing step can be completely removed.

[0033] This embodiment and Figure 1 The main difference in the embodiments is that the liquid used in this embodiment contains mosquito-repellent ingredients and dyeing ingredients, which can simultaneously give the shell the desired color and mosquito-repellent effect.

[0034] Please refer to the above as well. Figure 4 , Figure 4 show Figure 3 An embodiment of step S320 in the process.

[0035] As shown in the figure, firstly, as described in step S410, a mosquito repellent powder is prepared. This mosquito repellent powder may contain a powder composed of natural mosquito repellent ingredients such as ethyl butyl acetaminopropionate, p-menthane-3,8-diol, citronellol, limonol, and eucalyptus.

[0036] Subsequently, as described in step S420, the mosquito repellent powder is added to pure water and ground and filtered to produce a mosquito repellent solution.

[0037] Then, as described in step S430, a dye is added to the mosquito repellent solution to produce the mosquito repellent dye concentrate. In one embodiment, the dye may be selected from the group consisting of natural dyes such as indigo, safflower, turmeric, and gardenia.

[0038] In one embodiment, steps S420 and S430 involve grinding the prepared mosquito repellent powder in an appropriate amount of pure water at high speed for 2-3 hours, adding pure water as needed during the process, and then filtering, for example, using a 3000-mesh double-layer filter gun, to obtain the mosquito repellent solution. In actual operation, the aforementioned filtration process is usually repeated 3-5 times.

[0039] Subsequently, the mosquito repellent solution is sealed and left to stand at room temperature for 48 hours before being filtered, for example, through a 3000-mesh filter. Then, the top 70% of the filtered mosquito repellent solution is extracted, and the prepared dye is added. Finally, the solution is microwaved for 24 hours in a constant temperature bath at 33-37 degrees Celsius.

[0040] Then, extract the top 90% volume of the solution after microwave treatment to obtain the mosquito repellent dye concentrate.

[0041] Next, as described in step S440, the mosquito repellent dye concentrate is mixed with pure water to prepare an appropriate ratio, thereby generating a liquid for soaking the casing. In one embodiment, step S440 involves completely dissolving 4%-8% of the mosquito repellent dye concentrate in pure water and controlling the temperature at 20-30 degrees Celsius. In another embodiment, the pure water added in the aforementioned steps S420 and S440 is ultrapure water.

[0042] The surface treatment method provided in this case allows for the injection of mosquito-repellent components into the casing through anodizing, thereby giving the casing mosquito-repellent properties. This prevents users from being easily bothered and bitten by mosquitoes while operating electronic devices such as laptops, tablets, and smartphones, thus improving the user experience.

[0043] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes and modifications without departing from the concept and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
