Detailed Description

Most of the traditional decontamination equipment stores decontamination liquid through a liquid storage tank and decontaminates the surface to be decontaminated by the decontamination liquid. In order to kill microorganisms on the surface to be decontaminated, conventional decontamination solutions mostly contain hypochlorous acid, alcohol and other active ingredients. The chemical properties of the effective components are always more active and may deteriorate along with the prolonging of storage time, so that the decontamination effect of the decontamination solution is deteriorated.

Therefore, in order to prevent the decontamination effect from being affected by the decontamination liquid deterioration, the liquid storage tank of the conventional decontamination equipment mostly needs to be specially designed, and the decontamination liquid can be isolated from the external environment. Therefore, the deterioration time of the decontamination solution can be delayed to a certain extent. But the method still has the possibility of deterioration of the decontamination solution. Therefore, not only a special liquid storage tank needs to be designed, but also the decontamination liquid stored in the liquid storage tank needs to be replaced regularly, which results in higher cost of the traditional decontamination equipment and needs regular maintenance.

In addition, since conventional decontamination solutions may act as biocides, the conventional decontamination solutions may have an effect on other organisms in the environment. Therefore, most of the traditional decontamination equipment also has a structure for recovering waste liquid, and is used for recovering and treating decontamination liquid after decontamination, so that the decontamination liquid is prevented from polluting the environment. Therefore, the chemical property of the decontamination liquid is active, so that the traditional decontamination equipment is complex in structure, high in cost and inconvenient to transport and manage.

In order to simplify the structure of the decontamination apparatus, the embodiment of the application provides a decontamination liquid generation apparatus and a decontamination liquid generation method. The following first describes a decontamination solution generating apparatus provided in an embodiment of the present application. It should be particularly noted that the decontamination solution generation apparatus provided in the embodiment of the present application may be an independent apparatus, may also be a part of the decontamination apparatus, and may also be a module for generating a decontamination solution in other apparatuses. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a decontamination solution generating apparatus 100 according to an embodiment of the present application. The decontamination solution generation apparatus 100 includes a gas generation unit 110, a gas-liquid mixing unit 120, and a concentration control unit 130.

The gas generating unit 110 is configured to generate a gaseous disinfectant, and input the gaseous disinfectant into the gas-liquid mixing unit 120, so that the gaseous disinfectant is mixed with a solvent in the gas-liquid mixing unit 120, or is mixed with a decontamination solution having a concentration that does not meet a requirement for a second time.

The gas-liquid mixing unit 120 is connected to the solvent source, and is configured to receive the solvent provided by the solvent source, and mix the gaseous disinfectant with the solvent to obtain the decontamination solution. Wherein the gaseous sterilizing agent is soluble in the solvent. For example, when the gaseous sterilant is ozone or chlorine, the solvent may be water. In some possible implementations, the gas-liquid mixing unit 120 may include at least one venturi ejector. For example, the jet device can be a venturi jet device, and can also be a set consisting of a plurality of venturi jet devices which are connected in an end-to-end manner. In some other implementations, the gas-liquid mixing unit 120 may also be an aeration head or the like.

The concentration control unit 130 may be, for example, a device such as a single chip microcomputer or a computer, or may be a software module running on a computer or a server. In the present embodiment, the concentration control unit 130 may be used to control the dissolution of the gaseous sterilant from the solvent, thereby controlling the concentration of the gaseous sterilant in the decontamination solution. Thus, the concentration of the gaseous disinfectant in the decontamination solution is adjusted by the concentration control unit 130, so that the concentration of the gaseous disinfectant in the generated decontamination solution can be ensured to be in a proper interval, and the decontamination solution can not only play a role in disinfection, but also cannot damage the surface to be decontaminated.

The embodiment of the application provides a decontamination solution generating device. The device comprises a gas generation unit, a gas-liquid mixing unit and a concentration control unit. The gas generating unit is connected with the gas-liquid mixing unit and is used for generating a gaseous disinfectant and inputting the gaseous disinfectant into the gas-liquid mixing unit; the gas-liquid mixing unit is connected with a solvent source and is used for receiving the solvent provided by the solvent source and mixing the gaseous disinfectant and the solvent into a decontamination solution, wherein the gaseous disinfectant is soluble in the solvent; the concentration control unit is used for controlling the concentration of the gaseous disinfectant in the decontamination solution. Therefore, the decontamination equipment can actively generate the gaseous disinfectant, and the gaseous disinfectant is dissolved in the solvent to obtain the decontamination solution. In this manner, the gaseous decontaminant required to generate the decontamination solution can be generated by the decontamination solution generation apparatus itself without the need for additional carry-over of a decontaminant agent. Compared with the prior art, the problems of leakage, deterioration and the like of the disinfectant in the storage process can be avoided.

The decontamination solution generating apparatus provided by the embodiments of the present application will be described with reference to a specific method for controlling the concentration of a gaseous decontaminant by the concentration control unit 130.

Referring to fig. 2, there is shown another schematic structural diagram of a decontamination solution generating device 100 according to an embodiment of the disclosure. In this figure, the gas-liquid mixing unit 120 of the decontamination liquid generating apparatus 100 includes a liquid outlet 121, a gas inlet 122, and a liquid inlet 123.

The liquid outlet 121 is used for outputting liquid in which gaseous disinfectant is dissolved, and is connected to other equipment, such as a decontamination unit or a liquid storage tank. The gas input 122 is coupled to the gas generating unit 110 for receiving the gaseous sterilizing agent generated by the gas generating unit 110. The liquid inlet 123 may be connected to the solvent source 140 and may also be connected to the liquid outlet 121 of the gas-liquid mixing unit 120. When the liquid input port 123 is connected to the solvent source 140, the solvent may be input from the solvent source 140 into the gas-liquid mixing unit 120 to be mixed with the gaseous disinfectant in the gas-liquid mixing unit 120 to obtain a preliminarily mixed decontamination solution.

The concentration control unit 130 may then detect the dissolution of the gaseous decontaminant in the preliminary mixed decontamination solution. If the concentration of the gaseous decontaminant in the decontamination solution is higher than the first concentration threshold, the concentration control unit 130 may control the outlet 121 of the gas-liquid mixing unit 120 to be directly connected to other equipment (e.g., a tank or a decontamination unit). Wherein the first concentration threshold may be a minimum concentration of the gaseous decontaminant in the decontamination solution provided that the decontamination solution is capable of performing a decontamination function. Alternatively, in the embodiment of the present application, the first concentration threshold may be preset in the concentration control unit 130, or may be configured actively by a technician when the decontamination solution needs to be generated.

If the concentration control unit 130 determines that the concentration of the gaseous disinfectant in the decontamination solution is below the first concentration threshold, it indicates that the concentration of the gaseous disinfectant in the decontamination solution is low, and it may not be possible to decontaminate the surface to be decontaminated, and it is desirable to increase the concentration of the gaseous disinfectant in the decontamination solution. Therefore, the concentration control unit 130 can input the decontamination liquid output from the liquid outlet 121 into the gas-liquid mixing unit 120 again from the liquid input port 123 of the gas-liquid mixing unit 120. Like this, the liquid that disinfects that tentatively mixes with gaseous state disinfectant once more, can improve the concentration of gaseous state disinfectant in the liquid that disinfects to it has sufficient gaseous state disinfectant to ensure to dissolve in the liquid that disinfects, can play better washing effect of disinfecting.

In the embodiment of the present application, a blocking device 150 may be disposed between the liquid input port 122 of the gas-liquid mixing unit 120 and the solvent source 140. The blocking unit 150 may be configured to prevent the decontamination solution output from the liquid outlet 123 from entering the solvent source 140 during the process of inputting the decontamination solution into the gas-liquid mixing unit 120 again from the liquid input port 122, i.e., prevent the decontamination solution from contaminating the solvent stored in the solvent source 140. The blocking unit 150 may be a one-way valve, a three-way valve, or a plurality or plurality of valves controlled by a control circuit to prevent the decontamination solution from contaminating the solvent source 140.

It should be noted that the determination by the concentration control unit 130 of whether the concentration of the gaseous disinfectant in the decontamination solution is below the first concentration threshold is merely one possible implementation manner provided by the embodiments of the present application. In some other implementations, the concentration control unit 130 may also detect whether the concentration of the gaseous decontaminant in the decontamination solution is above a second concentration threshold. The second concentration threshold may be, for example, a maximum concentration of the gaseous decontaminant in the decontaminant liquid without the decontaminant liquid causing damage to the surface or environment to be decontaminated. If the concentration of the gaseous disinfectant in the decontamination solution is greater than the second concentration threshold, the concentration control unit 130 may mix the decontamination solution output from the liquid outlet 121 with the solvent output from the solvent source 140, thereby diluting the decontamination solution and reducing the concentration of the gaseous disinfectant in the decontamination solution. The embodiment of the present application is not limited to the specific manner in which the concentration control unit 130 controls the concentration of the gaseous disinfectant in the decontamination solution.

In the embodiment of the present application, the gaseous disinfectant may be ozone, and accordingly, the apparatus may further include an ozone concentration detecting unit for detecting the concentration of the gaseous disinfectant in the decontamination solution generated by the gas-liquid mixing unit 120. Alternatively, the gas generating unit 110 may be a high-pressure discharge type ozone generating device, or an electrolytic water type ozone generating device.

The following description is made in detail with reference to specific application scenarios.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a decontamination solution generating device 200 according to an embodiment of the present disclosure. In the embodiment shown in fig. 3, the decontamination solution generating device 200 includes a gas generating unit 210, a gas-liquid mixing unit 220, a concentration control unit 230, a solvent source 240, a three-way valve 250, and a decontamination unit 260. The gas-liquid generating unit 210 is connected to a gas input port 221 of the gas-liquid mixing unit through a gas conveying device (not shown in the figure, for example, a gas pipe), the solvent source 240 is connected to a liquid input port 222 of the gas-liquid mixing unit 220 through a liquid conveying device (not shown in the figure, for example, a liquid pipe) and a three-way valve B260, a liquid outlet 223 of the gas-liquid mixing unit 220 is connected to a decontamination unit through a liquid conveying device and a three-way valve a250, and the concentration control unit 230 is connected to the three-way valve a250 and the three-way valve B260 through a wired connection or a wireless connection. The concentration control unit 239 is also connected to a concentration sensor (not shown in the figure) in the gas-liquid mixing unit 220.

The three-way valve a250 includes a first inlet a1, a first outlet A2, and a second outlet A3, and the three-way valve B260 includes a first inlet B1, a second inlet B2, and a first outlet B3. The first inlet a1 of the three-way valve a250 is connected with the liquid outlet 223 of the gas-liquid mixing unit 220, the first outlet A2 of the three-way valve a250 is connected with the second inlet B2 of the three-way valve B, the second outlet A3 of the three-way valve a250 is connected with the decontamination unit 270, the first inlet B1 of the three-way valve B is connected with the solvent source 240, and the first outlet B3 of the three-way valve B is connected with the liquid inlet 222 of the gas-liquid mixing unit 220.

When the decontamination solution needs to be generated, the control unit can generate and send a decontamination solution generation instruction. The decontamination liquid generation unit is used for generating decontamination liquid. Alternatively, the control unit may be the concentration control unit 230, or may be another control unit.

The gas generation unit 210 may receive a decontamination solution generation instruction, upon which the gas generation unit 210 may generate a gaseous decontaminant. For example, assume that the gaseous sterilant is ozone and that the gas generating unit 210 comprises an electrolytic water ozone generator. Then, the gas generating unit 210 may be energized to generate ozone by electrolyzing water. After generating the gaseous sterilizing agent, the gas generating unit 210 may input the gaseous sterilizing agent into the gas-liquid mixing unit 220 from the gas input port 221 through the gas delivery device.

When the decontamination solution generation command is first received, the three-way valve B260 may open the first inlet B1, close the second inlet B2, and open the first outlet B3. In this manner, the solvent from the solvent source 240 may enter the liquid input port 222 of the gas-liquid mixing unit 220 through the first inlet B1 and the first outlet B3, so as to be mixed with the gaseous disinfectant in the gas-liquid mixing unit 220, thereby obtaining a preliminarily mixed decontamination solution. The preliminarily mixed decontamination liquid may flow from the liquid outlet 223 of the gas-liquid mixing unit 220 into the first inlet a1 of the three-way valve a 250.

The concentration control unit 230 may detect the concentration of the gaseous disinfectant in the decontamination solution flowing out of the liquid port 223 by a concentration sensor. If the concentration of the gaseous decontaminant in the decontamination liquid is satisfactory, for example, the concentration of the gaseous decontaminant is greater than or equal to the first concentration threshold, the concentration control unit 230 may control the first outlet A2 of the three-way valve a250 to be closed and the second outlet A3 to be open. In this way, decontamination solution generated by the gas-liquid mixing unit 220 may be directed into the decontamination unit 270 for decontaminating a surface to be decontaminated.

If the concentration control unit 230 determines that the concentration of the gaseous sterilant in the decontamination solution output from the solution port 223 is unsatisfactory, for example, the concentration of the gaseous sterilant is less than the first concentration threshold, indicating that the decontamination solution may not be effective, the concentration control unit 230 may control the first outlet A2 of the three-way valve a250 to open, the second outlet A3 to close, and the first inlet B1 of the three-way valve B260 to close, and the second inlet B2 to open. Thus, the decontamination liquid output from the liquid outlet 223 enters the gas-liquid mixing unit 220 from the liquid inlet 222 through the three-way valve a250 and the three-way valve B260, and is mixed with the gaseous disinfectant again in the gas-liquid mixing unit 220. Therefore, the concentration of the gaseous disinfectant in the decontamination solution can be improved by mixing the decontamination solution and the gaseous disinfectant for multiple times, and the decontamination effect is ensured.

In some possible implementations, the concentration control unit 230 may also control the opening of the first inlet B1 of the three-way valve B260 to allow the solvent source and the preliminarily mixed decontamination solution to be input into the gas-liquid mixing unit 220 again from the liquid input port 222. In this way, excessive concentrations of gaseous disinfectant in the decontaminant solution can be avoided for multiple mixing.

In some possible implementations, the decontamination solution generation apparatus may further include a decontamination unit for ejecting a decontamination solution to decontaminate the surface to be decontaminated. In the embodiment of the application, the decontamination unit can be a spray head or a special decontamination head. One possible implementation of the decontamination unit is described in detail below.

In the embodiment of the present application, the sprayed decontamination liquid may be pumped away by a pump in consideration of the treatment of the decontamination liquid. Specifically, the decontamination unit may include a first pipe, a second pipe, a first pump, and a decontamination head, and the detailed structure of the decontamination head may be as shown in fig. 4.

Wherein, the decontamination head is provided with two openings which are respectively connected with the first end of the first pipeline and the first end of the second pipeline. A second end of the first pipe is connected to the gas-liquid mixing unit 120, and a second end of the second pipe is connected to the first pump. Thus, when the first pump is operated, the second end of the second pipe generates a low pressure. By conduction through the second conduit, a low pressure also occurs at the first end of the second conduit. When the decontamination head works, the air pressure inside the decontamination head is consistent, namely the air pressure at the first end of the first pipeline is consistent with that at the first end of the second pipeline. Then, because the air pressure at the first end of the second pipeline is lower, the decontamination liquid sprayed out from the first end of the first pipeline enters the second pipeline from the first end of the second pipeline, and the recovery treatment of the waste liquid is realized.

In one possible implementation, to ensure that the first end of the first pipe and the first end of the second pipe are close in air pressure, the decontamination unit may further comprise an air pressure maintaining unit. The air pressure maintaining unit may contact the surface to be decontaminated, may maintain the first end of the first conduit and the first end of the second conduit in proximity, and may prevent the decontaminating liquid from flowing off the surface to be decontaminated.

In a possible implementation manner, the decontamination liquid generation apparatus provided by the embodiment of the present application may further include a fixing device for fixing the gas generation unit and the gas-liquid mixing unit. Optionally, the fixture may further comprise moving means for moving the decontamination liquid generating device.

The above provides some specific implementation manners of the decontamination liquid generation device for the embodiments of the present application, and based on this, the present application also provides a corresponding decontamination liquid generation method and a concentration control method.

First, a method of generating a decontamination solution will be described.

Referring to fig. 5, fig. 5 is a flowchart of a method of generating a decontamination solution according to an embodiment of the present application, including:

s501: and receiving a disinfectant generation instruction, and controlling the gas generation unit to generate the gaseous disinfectant.

S502: and controlling a gas-liquid mixing unit to mix the gaseous disinfectant and the solvent to obtain the decontamination solution.

Wherein, the gas generating unit and the gas-liquid mixing unit belong to the decontamination liquid generating equipment, and the solvent is from a solvent source.

The embodiment of the application provides a decontamination solution generation method. The method can control the decontamination equipment to actively generate the gaseous disinfectant, and dissolve the gaseous disinfectant in the solvent to obtain the decontamination solution. In this manner, the gaseous decontaminant required to generate the decontamination solution can be generated by the decontamination solution generation apparatus itself without the need for additional carry-over of a decontaminant agent. Compared with the traditional technology, the problems of leakage, deterioration and the like of the disinfectant in the storage process can be avoided.

The decontamination solution generation method provided by the embodiment of the application can be applied to the decontamination solution generation equipment. For example, may be applied to a control unit in a decontamination solution generating device. Alternatively, the control unit may be a computer or a single chip for controlling the decontamination liquid generating device. Alternatively, the decontamination liquid generation method may be stored in a storage module of a computer in the form of a computer storage medium, or may be implemented in a hardware manner, such as an integrated circuit or a logic circuit.

The concentration control method is described below.

Referring to fig. 6, fig. 6 is a flowchart of a method of controlling concentration according to an embodiment of the present application, including:

s601: the concentration of gaseous disinfectant in the decontamination solution is detected, the decontamination solution is obtained by mixing the gaseous disinfectant and a solvent in a gas-liquid mixing unit, the gaseous disinfectant is generated by a gas generating unit, and the gas sounding unit and the gas-liquid mixing unit belong to decontamination solution generating equipment.

S602: in response to the concentration being below a first concentration threshold, controlling the gas-liquid mixing unit to mix the decontamination liquid with the gaseous decontaminant.

The concentration control method provided by the embodiment of the application can judge whether the concentration of the gaseous disinfectant in the decontamination liquid is lower than a first concentration threshold value or not, so as to determine whether the decontamination liquid can decontaminate the surface to be decontaminated or not. If the concentration is lower than the first threshold value, the decontamination effect of the decontamination solution is poor, and the concentration of the gaseous disinfectant in the decontamination solution needs to be increased. Then, the decontamination solution generated by the gas-liquid mixing unit may be input again to the gas-liquid mixing unit. Like this, the liquid that disinfects that tentatively mixes with gaseous state disinfectant once more, can improve the concentration of gaseous state disinfectant in the liquid that disinfects to it has sufficient gaseous state disinfectant to ensure to dissolve in the liquid that disinfects, can play better washing effect of disinfecting.

It should be noted that depending on whether the concentration of the gaseous decontaminant in the decontamination solution is below the first concentration threshold is merely one possible implementation provided by the embodiments of the present application. In some other implementations, it may also be detected whether the concentration of the gaseous decontaminant in the decontamination liquid is above a second concentration threshold. The second concentration threshold may be, for example, a maximum concentration of the gaseous decontaminant in the decontaminant liquid without the decontaminant liquid causing damage to the surface or environment to be decontaminated. If the concentration of the gaseous decontaminant in the decontaminant solution is greater than the second concentration threshold, the resulting decontaminant solution may be mixed with a solvent to dilute the decontaminant solution and reduce the concentration of the gaseous decontaminant in the decontaminant solution. The embodiment shown in fig. 6 provides only a means for increasing the concentration of gaseous sterilant in the decontamination solution, and those skilled in the art will be able to contemplate methods for decreasing the collective concentration of gaseous sterilant in the decontamination solution, and will not be described in detail herein.

The concentration control method provided by the embodiment of the application can be applied to the concentration control unit in the decontamination liquid generation equipment. Alternatively, the concentration control unit and the aforementioned control unit may be the same or different. The concentration control method may be stored in a storage module of a computer in the form of a computer storage medium, or may be implemented in hardware such as an integrated circuit or a logic circuit.

Optionally, the instruction corresponding to the decontamination liquid generation method and the instruction corresponding to the concentration control method may be carried in the same computer-readable storage medium, or may be carried in different computer-readable storage media.
