Of course, the sterilization device can also be applied to equipment such as a humidifier, a dehumidifier, an integrated air conditioner (such as a mobile air conditioner) and the like. In order to further increase the sterilization rate of the sterilization device, the present invention makes the following improvements to the internal structure of the sterilization device.
Referring to fig. 1 to 4, in an embodiment of the present invention, the sterilization apparatus includes:
the shell 100 is provided with an air inlet 110 and an air outlet 120, an air cavity is formed in the shell 100, and the air inlet 110 and the air outlet 120 are communicated with the air cavity;
an air resistance 200 arranged in the air chamber; the method comprises the steps of,
a sterilizing substance generator 300 is provided in the air chamber, and the sterilizing substance generator 300 is configured to release a sterilizing substance toward the upstream of the air resistance member 200 in the flow direction of the air.
Specifically, the sterilizing material generator 300 includes, but is not limited to, a sterilizing gas releasing device and an electrolysis device, wherein the electrolysis device can generate strong oxidizing materials through electrolysis of water, sodium sulfate solution, sodium chloride solution and the like, the strong oxidizing materials can escape out of the water surface, a strong oxidizing material cloud with a certain concentration is formed above the electrolysis tank 310 (wind chamber), and when air enters the wind chamber, bacteria in the air can be killed by the strong oxidizing material cloud.
In addition, the air resistance member 200 refers to an article such as a wet film, a filter screen, etc., which has a certain resistance to air but can allow air to pass through slowly. It can be appreciated that the air resistance member 200 can prevent air from being blocked, so that the contact time between the sterilizing material and the air can be prolonged, and the sterilizing material can kill bacteria in the air more completely.
According to the technical scheme, the sterilizing substance generator 300 releases the sterilizing substance towards the upstream of the air resistance piece 200, and a certain resistance is formed on the air through the air resistance piece 200, so that the contact time of the air and the sterilizing substance is prolonged, the bacteria in the air are killed more completely, and the sterilizing rate is effectively improved; the diffusion of strong-oxidability sterilizing substances into the indoor environment can be reduced, and secondary pollution and damage to indoor articles are avoided; in addition, since the air-permeable component (such as a wet film) does not need to directly absorb the strong oxidative sterilization liquid, the air-permeable component is prevented from being corroded by the sterilization liquid, and thus the service life of the air resistance component 200 can be prolonged.
Further, as shown in fig. 2, the sterilizing substance generator 300 includes an electrolytic cell 310, a positive electrode 320, and a negative electrode 330, the electrolytic cell 310 being configured to receive an electrolyte solution, the positive electrode 320 and the negative electrode 330 being disposed in the electrolytic cell 310. The electrolyte solution comprises, but is not limited to, sodium chloride solution (saline solution), sodium sulfate solution, water and the like, and generates gas and escapes from the water surface during electrolysis, a frame structure forms a strong oxidizing substance cloud with a certain concentration on the water surface, and bacteria in the electrolyte solution are killed when air flows through the area.
Specifically, when the electrolyte solution is a sodium chloride solution, naCl and H in the sodium chloride solution after being electrified 2 O is ionized and H is generated at positive electrode 320 and negative electrode 330, respectively 2 And Cl 2 While the remaining hydroxide ions combine with sodium ions to form sodium hydroxide (NaOH), while chloride ions or chlorine gas combine with sodium hydroxideSodium chloride and sodium hypochlorite (NaClO) are formed by the solution contact. Wherein, the sodium hypochlorite is unstable in water, hypochlorous acid is formed after hydrolysis, and the hypochlorous acid is further decomposed to form nascent chlorine [ Cl ]]And nascent oxygen [ O ]]Finally generating chlorine and oxygen, nascent chlorine [ Cl ]]Oxygen [ O ] of new ecology]And the extremely strong oxidizing nature of chlorine causes the proteins of the bacteria and viruses to denature, thus killing the pathogenic microorganisms.
When the electrolyte solution is sodium sulfate solution or water, the electrolyte solution can generate hydroxyl free radicals (-OH) and other oxidizing substances after being electrified, the hydroxyl free radicals are important active oxygen, and the electrolyte solution has extremely strong electron-obtaining capability, namely oxidizing capability, and can also denature the proteins of thalli and viruses, so that pathogenic microorganisms are killed. Of course, sodium sulfate solution has a stronger conductive effect and higher electrolysis efficiency than water.
Wherein, as shown in fig. 2, the electrolytic cell 310 is provided in an open state, and the opening of the electrolytic cell 310 is located upstream of the air resistance member 200 in the flow direction of the air. It will be appreciated that the electrolytic cell 310 is provided in an open configuration to facilitate the release of more highly oxidizing sterilizing material into the air chamber. In addition, the opening of the electrolytic cell 310 is located upstream of the air resistance member 200 so that the strongly oxidizing sterilizing substance escapes from the water surface of the electrolytic cell 310 and then directly reaches the upstream of the air resistance member 200, thereby rapidly sterilizing the bacterial virus in the air.
Further, as shown in fig. 2, the positive electrode 320 and the negative electrode 330 are provided in plurality, and the plurality of positive electrodes 320 and the plurality of negative electrodes 330 are alternately arranged in the electrolytic tank 310, so that a plurality of pairs of positive and negative electrodes 330 are formed in the electrolytic tank 310, that is, each adjacent positive electrode 320 and negative electrode 330 can ionize the electrolyte solution after being electrified, so that the efficiency of electrolysis of the electrolyte solution is improved, more strong oxidizing substances can be released into the air cavity above the electrolytic tank 310 in unit time, and the sterilization rate of the sterilization device to indoor air is improved.
Alternatively, the positive electrode 320 and the negative electrode 330 are electrode plates, and the materials of the positive electrode 320 and the negative electrode 330 include simple substances or oxides of at least one element of Pt, ir, ru, au, ag, pd, pb, sn, sb, bi and Ti. Among them, noble metal electrodes have higher electrolysis efficiency but higher cost, and non-noble metals have lower electrolysis efficiency but lower cost, so that suitable electrode materials can be selected by comprehensively considering various factors.
Further, the air resistance 200 includes a wet film or a screen. Air resistance 200 refers to an article that presents some resistance to air but is capable of allowing air to pass slowly through, such as a wet film, a screen, and the like. The wet film is made of plant fiber as base material and through resin treatment and sintering with special components, corrugated plate-shaped crossed and overlapped polymer composite material is formed. The wet film has a certain resistance to air, thereby being capable of prolonging the contact time of the air and the sterilizing substance so as to kill bacteria in the air more completely. Meanwhile, the wet film can also effectively adsorb highly-oxidative degerming substances, so that the degerming substances are prevented from being diffused into the indoor environment through the air outlet 120, and secondary pollution or damage is avoided. It should be noted that the wet film may be placed in a dry state in the sterilization apparatus. Of course, the wet film may also be present in a wet state, in particular, by being immersed in water, or by being wetted by spraying. The wet film can transform the dry air passing therethrough into wet air and send the wet air out of the air outlet 120, thereby effectively improving the humidity and comfort of the air. The wet film can effectively dissolve strong oxidizing substances such as chlorine, so that the strong oxidizing substances such as chlorine can be prevented from being blown out from the air outlet 120, and excessive chlorine floating in the indoor environment can be avoided.
In addition, the filter screen also has a certain resistance to air, and has an obvious filtering and purifying effect on the air. For example, high efficiency screens (HEPA screens) are effective in filtering most particulate dust and aerosols from the air. So, when the air gets into in the sterilizing equipment, at first through the wind chamber, the sterilizing substance that the sterilizing substance generator 300 released at this moment can kill the bacterial virus in the air, then the filter screen filters most granule dust and suspended solid in the air again, and this embodiment technical scheme can further purify the air, promotes the quality of indoor air.
In one embodiment, as shown in fig. 1, the air resistance member 200 is disposed at one end of the sterilizing material generator 300 near the air outlet 120. That is, the sterilizing substance generator 300 is disposed in front of the air resistance member 200, so that air passes over the sterilizing substance generator 300, passes through the air resistance member 200, and is finally discharged from the air outlet 120. It can be appreciated that the air resistance piece 200 is close to the air outlet 120 and is shielded between the air cavity and the air outlet 120, so as to block air, prevent air from being directly and quickly sent out through the air outlet 120 when flowing through the air cavity, prolong the contact time between the degerming substance and the air, and enable the degerming substance to kill bacteria in the air more completely. Specifically, the air resistance member 200 may have a rectangular structure with one side, and is disposed only at one end of the sterilizing material generator 300 near the air outlet 120. Of course, in other embodiments, the air resistance member 200 may have a square, round, trapezoid shape, etc., which is not limited in the present invention, so long as the air resistance member 200 can play a role in blocking air.
In another embodiment, as shown in fig. 3 and 4, the air resistance member 200 is disposed around the circumference of the sterilizing material generator 300, the air inlet 110 is disposed at the top or bottom of the housing 100, and the air outlet 120 is disposed on the circumference of the housing 100. It will be appreciated that in this embodiment, the air resistance member 200 has a ring-shaped structure, the sterilizing material generator 300 is disposed inside the ring-shaped air resistance member 200, and wind is blown into the inside of the ring-shaped air resistance member 200 from the top or bottom of the housing 100, passes over the sterilizing material generator 300, passes through the air resistance member 200, and is blown out along the circumferential side of the air resistance member 200. According to the technical scheme of the embodiment, the annular air resistance piece 200 is arranged around the degerming substance generator 300, so that the contact time of air and degerming substances can be further prolonged, and the degerming rate is further improved.
In this embodiment, the air resistance member 200 is a square frame structure or a cylindrical structure. It can be appreciated that by arranging the air resistance member 200 in a regular ring-shaped structure, the manufacturing and assembly of the air resistance member 200 are facilitated, and meanwhile, the air resistance member 200 is facilitated to surround the sterilizing material generator 300 well, so that the contact between the air and the sterilizing material inside the air resistance member 200 in a square frame structure or a cylinder structure can be ensured as long as possible, and the sterilizing material can be killed better. It should be noted that, one of the upper end and the lower end of the air resistance member 200 of the square frame structure or the cylinder structure is opened to facilitate air introduction, and the other end is closed to prevent air from escaping from the port, which would cause air flow dispersion to be unfavorable for sterilization.
In addition, it is understood that the sterilization device further includes a wind wheel, optionally, the wind wheel is disposed at the air inlet 110 or the air outlet 120 or in the air cavity. It will be appreciated that air flow may be directed and air circulation may be facilitated by the wind wheel.
In order to better embody the sterilization rate of the sterilization apparatus according to the technical scheme of the present invention, the sterilization rates of the sterilization apparatuses of the examples and comparative examples will be compared with each other in the following manner in conjunction with table 1.
Example 1: as shown in fig. 1, this embodiment provides a sterilizing apparatus, and a sodium chloride solution is introduced into an electrolytic cell 310 of the sterilizing apparatus, and a positive electrode 320 and a negative electrode 330 are electrically connected to electrolyze the sodium chloride solution, wherein the current is 1.5A.
Example 2: as shown in fig. 1, this embodiment provides a sterilizing apparatus, and a sodium sulfate solution is fed into an electrolytic cell 310 of the sterilizing apparatus, and a positive electrode 320 and a negative electrode 330 are electrically connected to electrolyze the sodium sulfate solution, wherein the current is 1.5A.
Comparative example 1: as in example 1, the sodium chloride solution was introduced into the electrolytic cell 310 of the sterilizing apparatus, but the positive electrode 320 and the negative electrode 330 were not electrically connected, that is, the sodium chloride solution was not electrolyzed.
Comparative example 2: as in example 2, sodium sulfate solution was introduced into the electrolytic cell 310 of the sterilizing apparatus, but the positive electrode 320 and the negative electrode 330 were not electrically connected, that is, the sodium sulfate solution was not electrolyzed.
As shown in table 1, in comparative examples 1 and 2, when the positive electrode and the negative electrode are not energized, a certain sterilization rate but a low sterilization rate is also obtained by placing a sodium chloride solution or a sodium sulfate solution in the electrolytic cell 310, because the life of bacteria is naturally attenuated and self-extinguished in general. By comparing the examples with the comparative examples, it is apparent that the sterilization rate of the examples is significantly higher than that of the comparative examples, thereby demonstrating that a large amount of sterilization substances can be released upstream of the air resistance member 200 by electrolysis of sodium chloride solution and sodium sulfate solution, and a certain resistance is formed to the air by the air resistance member 200, so that the contact time of the air and the sterilization substances is prolonged, and the sterilization of bacteria in the air is more complete, thereby effectively improving the sterilization rate. In addition, it was found from comparative examples 1 and 2 that the sterilizing rate in the electrolysis of the sodium chloride solution was significantly higher than that in the electrolysis of the sodium sulfate solution because nascent chlorine, nascent oxygen and chlorine gas generated in the electrolysis of the sodium chloride solution have strong oxidizing property, can effectively kill bacteria and viruses, and the residence time of chlorine gas in the air was long, further improving the sterilizing rate. The life of hydroxyl radical generated when the sodium sulfate solution is electrolyzed is short, and the hydroxyl radical exists only a certain distance above the liquid surface, so that the contact time of the degerming substance and bacteria and viruses in the air is insufficient, and the degerming rate is low.
