TECHNICAL FIELD

The disclosure relates to the technical field of disinfection application, particularly, to a device capable of disinfecting a ventilator as well as a face mask and a hose, and more particularly, to an ozone disinfection device, an ozone disinfection system, and an ozone disinfection method.

BACKGROUND

At present, ozone disinfection methods are commonly used in the fields of medical equipment, catering tableware, food processing, etc. Ozone disinfection is highly efficient and economical. In ozone disinfection of items, items to be disinfected need to be placed in a sealed space, and ozone is fed into the sealed space to achieve disinfection. The ozone feeding space is relatively sealed, and high concentration of ozone is required to achieve full disinfection. As a result, after the items are disinfected, part of the ozone remains in the sealed space. For example, the ozone remains inside a ventilator or in a ventilator tube. The ozone cannot be completely eliminated in a short period of time, and when a user takes out the items, a pungent smell will be diffused. On the other hand, a large amount of ozone inhalation will also harm human health. At present, none of devices and products for ozone disinfection of a ventilator on the market actively recycle ozone. The characteristic of active elimination is that a device may actively recycle all the remaining ozone generated, so that all these ozone may be filtered through an ozone filter and catalytically decomposed, thereby achieving a safe and reliable effect. Unlike a passive technology, the passive technology refers to placing a filter at a certain position in a disinfection space and simply adsorbing ozone through the surface without an external force. The effect of this technology is not good and the efficiency is low, and only the ozone around the filter can be simply adsorbed while the ozone remaining in other spaces such as hoses cannot be effectively adsorbed.

The above content is only used to help understand the technical solutions of this application, and does not mean that the above content is recognized as the prior art.

SUMMARY

Still another technical problem to be solved by the disclosure is to provide an ozone disinfection method.

In order to solve the above technical problems, the technical solution adopted by the disclosure is to provide an ozone disinfection device, which includes:

The present embodiment provides an ozone disinfection device100. The ozone disinfection device100is particularly suitable for disinfecting a ventilatory apparatus. The ventilatory apparatus includes a ventilator600, a hose602, and a face mask603that communicate in sequence. It can be understood that the ventilator600and the face mask603are connected by the hose602, the ventilator600and the hose602are of a detachable connection structure, and the face mask603and the hose602are of a detachable connection structure.

In the present embodiment, the sealed disinfection space102is opened and closed in a drawer type. Specifically, referring toFIG. 1,FIG. 3, andFIG. 7, the ozone disinfection device100includes an outer box and an inner box. The outer box includes a top cover, a base101, and a peripheral side wall connected between the top cover and the base101. A front side of the peripheral side wall is provided with a mounting hole into which the inner box can be inserted. The inner box has an opening on its upper end, and internally has the sealed disinfection space102. The through hole104is provided on a front side of the inner box. When the inner box is inserted into the outer box from the mounting hole, the opening on the upper end of the inner box is sealed. At this time, the sealed disinfection space102can only communicate with the outside through the through hole104. That is, if the through hole104is blocked, gas in the sealed disinfection space102will not escape.

In some other embodiments, the sealed disinfection space102may also be opened and closed in a flip type. A specific structure will not be described in detail in the disclosure. It should be understood that this is also the technical solution claimed by the disclosure.

In the present embodiment, referring toFIG. 3, the ozone generation unit300, the suction pump400, and the filter500are all fixed to the base101. The sealed disinfection space102is located on upper sides of the ozone generation unit300, the suction pump400, and the filter500. Specifically, when the inner box is inserted into the outer box, the inner box is located just above the base101, and the ozone generation unit300, the suction pump400, and the filter500are all located between the inner box and the base101. By such design, an internal space of the outer box is fully utilized, making the entire ozone disinfection device100miniaturized and enhancing its portability.

In the present embodiment, referring toFIG. 3, the ozone generation unit300communicates with the first interface of the gas distribution unit200through a first pipeline201. The suction port401of the suction pump400communicates with the third interface of the gas distribution unit200through a third pipeline203. The exhaust port402of the suction pump400communicates with the gas inlet501of the filter500through a fourth pipeline204. The second interface of the gas distribution unit200communicates with the gas inlet end601of the device to be disinfected through a second pipeline202. Preferably, the material of the first pipeline201, the second pipeline202, the third pipeline203, and the fourth pipeline204is silica gel.

In some other embodiments, the material of the first pipeline201, the second pipeline202, the third pipeline203, and the fourth pipeline204may also be Ethylene Propylene Diene Monomer.

In the present embodiment, the gas distribution unit200is a three-way pipe.

In the present embodiment, the filter500has the plurality of exhaust holes502. Specifically, referring toFIG. 4, the filter500includes a hollow housing, the housing has the plurality of exhaust holes502and the gas inlet501, the gas inlet501is provided on lower sides of the plurality of exhaust holes502, at least one filter layer504is disposed between the gas inlet501and the exhaust holes502, and the housing internally has a buffer cavity503that is located on a lower side of the lowermost filter layer504and communicates with the gas inlet501of the filter500. Since the filter500has a plurality of exhaust holes502, non-polluting gas generated by the catalytic decomposition of ozone may be expelled more quickly, thus improving the ventilation efficiency of the filter500. In addition, considering that solid particles such as fine dust may be included in fast-flowing ozone gas, the buffer cavity503is designed inside the housing, which functions to collect the solid particles included in the ozone gas for centralized removal. Preferably, two filter layers504are disposed between the gas inlet501and the exhaust holes502, and there is a gap between the two filter layers504. Therefore, the catalytic ozone decomposition ability and efficiency of the filter500may be improved to ensure that no ozone is included in the gas expelled from the filter500. Here, at least one of the filter layers504is filled with manganese-containing particulate matters for catalytic ozone decomposition, so the ozone flowing through the filter500is decomposed into non-toxic and non-polluting oxygen under the action of the particulate matters to ensure the sanitation and safety of the surrounding environment.

In some other embodiments, three or more filter layers504may be disposed in the housing, and a certain gap is maintained between two adjacent filter layers504. The ozone flowing through the filter500flows in from the gas inlet501of the filter500, sequentially passes through the plurality of filter layers504, and then is expelled from the exhaust holes502. The ozone may be completely decomposed into non-toxic and non-polluting oxygen after being catalytically decomposed by the plurality of filter layers504. It should be noted that substances filled in each filter layer504may be the same, and of course, may be different, as long as they have the function of absorbing or catalyzing the decomposition of ozone.

In the present embodiment, the power apparatus is a positive pressure gas pump, so that the ozone generated by the ozone generator is quickly expelled into the second interface, that is, the ozone generated by the ozone generator does not enter the second interface through a slow diffusion process, thus improving the work efficiency of the entire ozone disinfection device100.

After the disinfection is completed, the control module700controls the ozone generation unit300to stop working and activates the suction pump400, the suction pump400generates a strong negative pressure, and pumps all the ozone remaining inside the sealed disinfection space102, the face mask603, the hose602, and the ventilator600to the filter500, and the filter500performs catalytic decomposition treatment on the ozone flowing through, and then evacuates, thereby eliminating the ozone remaining inside the sealed disinfection space102, the ventilator600, the hose602, and the face mask603, and protecting a user from inhaling the remaining ozone when using the disinfected ventilator600, hose602and face mask603while not causing ozone pollution to the surrounding environment. The safety and environmental protection of the ozone disinfection device100are improved. Compared with the existing passive ozone disinfection technology, the ozone disinfection device has the advantages of higher efficiency, high speed, safety, and environmental protection.

After the disinfection is completed, the control module700controls the ozone generation unit300to stop working and activates the suction pump400, the suction pump400generates a strong negative pressure and pumps all the ozone remaining inside the sealed disinfection space102, the face mask603, and the hose602to the filter500, and the filter500performs catalytic decomposition treatment on the ozone flowing through and then evacuates, thereby eliminating the ozone remaining inside the sealed disinfection space102, the hose602, and the face mask603, and protecting a user from inhaling the remaining ozone when using the disinfected hose602and face mask603while not causing ozone pollution to the surrounding environment.

The characteristic of the disclosure is a technology of active ozone elimination. The characteristic of active ozone elimination is that the ozone disinfection device100may actively recycle all the remaining ozone generated, so that all these ozone may be filtered through the ozone filter500and catalytically decomposed into non-toxic and non-polluting gas, thereby achieving a safe and reliable effect. Unlike a passive technology in the prior art, the passive technology refers to placing the filter500at a certain position in a disinfection space and simply adsorbing ozone through the surface without an external force. The effect of the passive technology is not good and the efficiency is low, and only the ozone around the filter500can be simply adsorbed while the ozone remaining in other spaces such as the hose602cannot be effectively adsorbed.

For the work principle, reference is made to the process of disinfecting the hose602and the face mask603using the ozone disinfection device100in Embodiment I.

Embodiment IV

The present embodiment provides an ozone disinfection method. The ozone disinfection method is implemented through the ozone disinfection device provided in Embodiment I.

In the present embodiment, the ozone disinfection method includes the following steps:

connecting a gas outlet end and a gas inlet end of a device to be disinfected to the sealed disinfection space102and the second interface, respectively;

activating, by the control module700, the ozone generation unit300, ozone generated by the ozone generation unit300flowing into the device to be disinfected and the sealed disinfection space102in sequence through the gas distribution unit200; here, the ozone generation unit300outputs a certain amount of ozone so that the concentration of ozone in the sealed disinfection space102is not lower than a concentration value capable of killing conventional germs inside a ventilator;

controlling, by the control module700, the ozone generation unit300to stop working and activating the suction pump400, generating, by the suction pump400, a strong negative pressure, and pumping all the ozone remaining inside the sealed disinfection space102and the device to be disinfected to the filter500; and

performing, by the filter500, catalytic decomposition treatment on the ozone flowing through and then evacuating.

In the present embodiment, the device to be disinfected includes a ventilator600, a hose602, and a face mask603. For the step of “connecting a gas outlet end and a gas inlet end of a device to be disinfected to the sealed disinfection space and the second interface, respectively,” the specific process is as follows: the ventilator communicates with the second interface through the second pipeline202, after the sealed disinfection space102is opened, the hose602is inserted into the sealed disinfection space102from the through hole104, the face mask603is put into the sealed disinfection space102, the ventilator600, the hose602, and the face mask603are connected in sequence, and then the sealed disinfection space102is closed.

In some other embodiments, the device to be disinfected may include only a hose602and a face mask603. Here, for the step of “connecting a gas outlet end and a gas inlet end of a device to be disinfected to the sealed disinfection space and the second interface, respectively,” the specific process is as follows: the hose602communicates with the second interface through the second pipeline202, after the sealed disinfection space102is opened, the hose602is inserted into the sealed disinfection space102from the through hole104, the face mask603is put into the sealed disinfection space102, the hose602and the face mask603are connected, and then the sealed disinfection space102is closed.
