Description

Technical Field

[0001] The present invention relates to the technical field of medical and health care and civilian disinfection supplies, and particularly relates to a wardrobe for disinfection using chlorine dioxide gas. Background Art

[0002] With the progress of science, the degree of pollution of people's living environment has increased rapidly. Especially in industrial developed areas and densely populated areas of big cities, the clothes, shoes, hats, and backpacks that people wear daily are extremely easy to be contaminated and adsorb droplets and dust containing bacteria and viruses. Therefore, a disinfection wardrobe should be set up at home, in hotels, and in restaurants to disinfect clothes, hats, and bags in time to prevent the spread of viruses. In particular, the sterilization and disinfection of the work clothes, clothes, and backpacks of medical workers are extremely important.

[0003] At present, the disinfection methods of the existing disinfection wardrobes on the market are to use ozone and ultraviolet lamps for sterilization and disinfection, and most of them have some problems. For example, the ultraviolet light irradiates in a straight line and has weak penetration. It can kill bacteria and viruses on the surface of clothes, but cannot disinfect bacteria adsorbed on the inner layer of clothes. Although ozone can diffuse to the fine parts of objects for disinfection, ozone is generated by decomposing oxygen molecules in the air through high-voltage discharge, and at the same time, nitrogen molecules in the air are ionized to generate nitrogen oxides, such as NO, NO2, etc. These are gases with peculiar smells and harmful to the human body. Since the wardrobe is not provided with devices for treating harmful gases remaining in the clothes, the disinfected clothes give people an uncomfortable feeling. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above-mentioned problems and provide a wardrobe for disinfection using chlorine dioxide gas.

[0005] The technical solution adopted by the present invention to achieve the above purpose is: a wardrobe for disinfection using chlorine dioxide gas, including a cabinet body. An inner box is arranged inside the cabinet body. A circulating air channel is formed between the inner wall of the cabinet body and the outer wall of the inner box. The inner box is provided with a corresponding inner box air inlet and an inner box air outlet. Both the inner box air inlet and the inner box air outlet are communicated with the circulating air channel. An inlet circulating air fan is installed at the inner box air inlet, and an outlet circulating air fan is installed at the inner box air outlet. A dry chlorine dioxide generator is installed at the circulating air channel at the inner box air inlet. The outlet of the dry chlorine dioxide generator is correspondingly arranged with the inner box air inlet.

Detailed implementation mode

[0018] As Figure 1 shown, the present invention is a wardrobe using chlorine dioxide gas for disinfection, including a cabinet body 1. An inner box 2 for hanging clothes is arranged inside the cabinet body 1. A circulating air channel 3 is formed between the inner wall of the cabinet body 1 and the outer wall of the inner box 2. The inner box 2 is provided with a corresponding inner box air inlet 4 and an inner box air outlet 5. The inner box air inlet 4 and the inner box air outlet 5 are both communicated with the circulating air channel 3. An inlet circulating air fan 6 is installed at the inner box air inlet 4, and an outlet circulating air fan 7 is installed at the inner box air outlet 5. A dry chlorine dioxide generator 8 is installed at the inner box air inlet 4 in the circulating air channel 3. The outlet of the dry chlorine dioxide generator 8 is correspondingly arranged with the inner box air inlet 4. The inlet circulating air fan 6, the outlet circulating air fan 7, and the dry chlorine dioxide generator 8 are all electrically connected to an electric control box 9. The electric control box 9 is installed in the circulating air channel 3. Filtration layers 10 are installed on both sides of the dry chlorine dioxide generator 8 in the circulating air channel 3. The filtration layers 10 are made of modified activated carbon fibers. The outlets of the filtration layers 10 are correspondingly arranged with the dry chlorine dioxide generator 8. Butterfly valves 11 are installed at the inlets of the filtration layers 10. When the butterfly valves 11 are opened, the filtration layers 10 are communicated with the circulating air channel 3, and the gas circulates through the filtration layers 10. When the butterfly valves are closed, the filtration layers are not communicated with the circulating air channel 3, and the gas does not pass through the filtration layers 10. The butterfly valves 11 are electrically connected to the electric control box 9. A spice box 12 is installed in the circulating air channel 3. The spice box 12 is located between the two filtration layers 10. The spice box 12 is electrically connected to the electric control box 9.

[0019] As Figure 2As shown in the figure, the dry chlorine dioxide generator includes paper tape 1 (803), paper tape 2 (804), a pressing mechanism, a slicer (806), and a chlorine dioxide generation box (808). Paper tape 1 (803) is loaded with sodium chlorite. Paper tape 1 (803) uses absorbent paper as a carrier, and an aqueous solution with a sodium chlorite content of 75%-85% (preferably 85%) is evenly sprayed on the absorbent paper in an amount of 55%-60% of the saturated adsorption capacity of the absorbent paper, and then formed after vacuum drying (pressure of 30 kPa - 40 kPa, temperature ≤ 30°C) to reduce the water content, and it is ensured that the tensile strength of paper tape 1 (803) is not less than 80% of the tensile strength of the absorbent paper; Paper tape 2 (804) is loaded with solid acid. Paper tape 2 (804) uses absorbent paper as a carrier, and an aqueous solution with a solid acid (which can be solid organic acids such as citric acid, oxalic acid, sulfonic acid, etc., or inorganic solid acids) content of 85%-95% (preferably 90%) is evenly sprayed on the absorbent paper in an amount of 80%-90% (preferably 85%) of the saturated adsorption capacity of the absorbent paper, and then formed after dehydration by vacuum drying (pressure of 50 kPa, temperature of 40°C - 50°C); Both paper tape 1 (803) and paper tape 2 (804) are wound into rolls and are rotatably installed on corresponding rotating shafts of the paper tape box (802). Paper tape 1 (803) and paper tape 2 (804) are pressed and conveyed to the slicer (806) through the pressing mechanism. The pressing mechanism includes a relatively arranged roller 1 (805) and roller 2 (801). Roller 1 (805) and roller 2 (801) rotate relatively, and a channel for conveying and pressing paper tape 1 (803) and paper tape 2 (804) is formed between them. The slicer (806) is correspondingly arranged at the entrance of the chlorine dioxide generation box (808). The outlet of the chlorine dioxide generation box (808) is correspondingly arranged at the inner box gas inlet 4. A fan (811) is installed at the outlet of the chlorine dioxide generation box (808). A purification layer (810) is arranged on the side of the fan (811) away from the chlorine dioxide generation box (808). The purification layer (810) is located inside the chlorine dioxide generation box (808). The purification layer (810) uses modified activated carbon fiber. A partition net (809) is installed on the side of the purification layer (810) away from the outlet of the chlorine dioxide generation box (808) to prevent the fragments in the chlorine dioxide generation box (808) from contacting the purification layer (810). The chlorine dioxide generation box (808) is provided with a bottom net door (807). When there are too many shredded papers after use in the chlorine dioxide generation box (808), the operator can open the bottom net door (807) to discard the shredded papers, and the discarded shredded papers are pollution-free garbage. The pressing mechanism, the slicer (806), and the fan (811) are all electrically connected to the electric control box 9. According to the usage needs, the opening time of the pressing mechanism, the slicer (806), and the fan (811) can be set through the electric control box 9, and the amount of pressed fragments generated, that is, the amount of corresponding chlorine dioxide gas generated, can be set according to the size and pollution degree of the wardrobe.

[0020] When in use, the clothes are hung in the inner box 2, and various parameters are set by adjusting the electric control box 9, including setting the disinfection start time, setting the amount of chlorine dioxide gas generated according to the degree of pollution of the clothes, setting the disinfection time, setting the running time, etc. When the time reaches the set start time, the inlet circulation fan 4 and the outlet circulation fan 5 operate synchronously, and the dry chlorine dioxide generator 8 starts to operate. At this time, the roller 1 805 and the roller 2 801 of the dry chlorine dioxide generator 8 rotate, the slicer 806 and the fan 811 start to operate, and the paper tape 1 803 and the paper tape 2 804 are driven and pressed together when passing through the roller 1 805 and the roller 2 801, and then transported to the slicer 806, and cut into pieces when passing through the slicer 806, and fall into the chlorine dioxide generating box 808, each pressed piece can generate a quantitative moist chlorine dioxide gas, and when the set amount of chlorine dioxide gas is released, the dry chlorine dioxide generator 8 stops working. The wet chlorine dioxide gas is brought into the purification layer 810 by the flowing gas generated by the fan 811 to remove moisture and dust, forming dry and pure chlorine dioxide gas, which is diffused to the inner box air inlet 4 through the fan 811, and then dispersed into the air of the inner box 2 through the inlet circulating air fan 6, and circulated among the inlet circulating air fan 6, the inner box 2, the outlet circulating air fan 7, and the circulating air channel 3. The clothes in the inner box 2 are contacted with the chlorine dioxide gas in the circulating gas for many times, so that the chlorine dioxide gas diffuses from the surface of the clothes to the fiber bundles inside the clothes for disinfection and sterilization. After a certain period of time, the two butterfly valves 11 are opened at the same time, and the gas in the circulating air channel 3 begins to circulate through the filter layer 10. After a certain period of operation, the dust falling off the clothes in the gas, the chlorine dioxide in the gas and other harmful gases and odors are removed by the filter layer, and then the fragrance box 12 is controlled to spray a small amount of natural fragrance, and the sterilization process is completed.

[0021] Taking an ordinary household disinfection cabinet as an example, after the clothes are put into the wardrobe, the operating parameters are set, the machine is turned on, the inlet circulation fan and the outlet circulation fan are running, and the dry chlorine dioxide generator runs for 5 minutes and then stops (it can produce 15-18mg of pure chlorine dioxide gas). After the gas circulates for 30 minutes, the two butterfly valves are opened. At this time, the gas circulates through the filter layer for 30 minutes and then stops, and the fragrance is sprayed for 0.5 seconds. The whole process is completed, and the clothes are sterile and have a faint fragrance.

[0022] Chlorine dioxide is a strong oxidant and is classified as a Class A1 safe disinfectant by the World Health Organization (WHO). It is a highly effective disinfectant with a broad-spectrum, highly effective and rapid bactericidal effect. The present invention uses pure chlorine dioxide gas to sterilize and disinfect clothing, and can also remove harmful gases remaining in clothing and eliminate odors. Moreover, the amount of chlorine dioxide gas produced and the disinfection time can be adjusted according to the degree of contamination of the clothing to make the clothing completely sterile.

[0023] As described above, it is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
