Description

Technical Field

[0001] This utility model relates to the field of disinfectant disinfection technology, and in particular to a loop disinfection device using a novel disinfectant. Background Technology

[0002] In industries such as medical care, food processing, and pharmaceuticals, the disinfection of equipment and pipelines is a crucial step. Traditional disinfection methods often employ high-temperature steam, chemical immersion, or ultraviolet irradiation, but these methods suffer from drawbacks such as cumbersome operation, long processing time, uneven disinfection, and corrosiveness to equipment materials. With advancements in technology and increasing demands for effective disinfection, a novel loop disinfection device using a new type of disinfectant has emerged.

[0003] Disinfectants include, but are not limited to, compound alcohols and ozone. Compound alcohol disinfectants, with ethanol and isopropanol as their main components, offer advantages such as good bactericidal effect, non-corrosiveness, and environmental safety. However, applying compound alcohol disinfectants to loop disinfection devices requires solving a series of technical problems. These include ensuring the safety of the disinfectant during addition, preventing corrosion and damage to device components, and achieving uniform atomization and effective circulation of the disinfectant.

[0004] Most existing circuit disinfection devices employ simple structural designs and lack proper layering and zoning, resulting in the mixing of electrical, gas, and liquid components. This not only increases operational difficulty but also reduces disinfection effectiveness. Furthermore, the addition of disinfectant often poses risks of leakage and splashing, endangering operator safety. In addition, existing atomization methods suffer from uneven atomization and excessively large particles, further impacting disinfection efficiency. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] like Figure 1 As shown, a loop disinfection device using a novel disinfectant includes an upper partition 10, a middle partition 20, and a lower partition 30 that are horizontally parallel from top to bottom.

[0040] The upper partition 10 is equipped with an atomizing cup 1 and a gas circuit sterilization device 2;

[0041] The lower partition 30 is equipped with a disinfectant supply box 3;

[0042] The atomizing cup 1 is provided with a liquid inlet 11, an atomizing port 12 and an air supply port 13;

[0043] A pressurized liquid supply component 5 is installed between the liquid inlet 11 and the disinfectant supply box 3 via a pressurized liquid supply pipeline 4. The pressurized liquid supply component 5 is used to pressurize the disinfectant in the disinfectant supply box 3 and inject it into the atomizing cup 1.

[0044] The atomizing port 12 is equipped with an atomizing pump 6, which is used to atomize the disinfectant in the atomizing cup 1;

[0045] The gas inlet 13 is connected to the inlet of the gas circuit disinfection device 2 via the outlet pipe 7. The outlet of the gas circuit disinfection device 2 is connected to the suction return pipe 8, and a suction return component 9 is installed on the suction return pipe 8. The gas circuit disinfection device 2 is used to disinfect the atomized disinfectant and output the disinfected disinfectant to a designated location through the suction return pipe 8. The suction return component 9 is used to ensure the smooth return of the disinfectant in the suction return pipe 8 and avoid blockage or leakage.

[0046] The pressurized liquid supply assembly 5, the atomizing pump 6, and the suction reflux assembly 9 are installed on the middle partition 20.

[0047] This circuit disinfection device uses a new type of disinfectant, mainly a compound alcohol disinfectant, and achieves a highly efficient and safe disinfection process through a precisely designed structure.

[0048] like Figure 1 As shown, the disinfection device in this circuit has an upper partition 10, a middle partition 20, and a lower partition 30 arranged horizontally from top to bottom for housing electrical, pneumatic, and hydraulic components. During operation, the compound alcohol disinfectant is stored in the disinfectant supply tank 3 installed in the lower partition 30. Through the pressurized liquid supply assembly 5, the disinfectant is pressurized and injected into the atomizing cup 1 located in the upper partition 10. During this process, due to the increased pressure within the sealed disinfectant supply tank 3 and the formation of a passage in the pressurized liquid supply pipeline 4, the compound alcohol disinfectant is automatically propelled into the atomizing cup 1 by the disinfectant supply tank 3 due to pressure. This design, which uses the pressurized liquid supply assembly 5 to indirectly add compound alcohol disinfectant to the atomizing cup 1, not only significantly reduces the negative impacts of the compound alcohol disinfectant on acids, alkalis, strong oxidants, and strong volatiles during the liquid supply process, but also ensures that operators can safely perform contactless operation, avoiding potential safety risks such as disinfectant leakage or splashing.

[0049] Next, the atomizing pump 6 located in the middle partition 20 starts working, atomizing the disinfectant in the atomizing cup 1 into disinfectant particles of different sizes. Large and medium-sized disinfectant particles fall back to the bottom of the atomizing cup 1, while small-sized particles are discharged from the air outlet 13 of the atomizing cup 1 with the airflow and enter the gas circuit disinfection device 2 through the output pipe 7. Inside the gas circuit disinfection device 2, the disinfectant particles mix with the air or gas in the gas circuit, thoroughly disinfecting the gas circuit.

[0050] After disinfection, the gas circuit disinfection device 2 discharges the disinfected gas and remaining disinfectant particles from its output port, and returns them to the designated location through the suction return pipeline 8. The suction return component 9 installed in the suction return pipeline 8 plays a crucial role in this process, ensuring the smooth return of disinfectant and gas and preventing blockages or leaks.

[0051] It is worth mentioning that, due to the rational layout of the upper partition 10, middle partition 20, and lower partition 30, these partitions not only support and fix the various components, but more importantly, they achieve the stratification and partitioning of the electrical, gas, and liquid components in the entire device, making the operation of the entire system more rational and stable. The electrical components, namely the pressurized liquid supply assembly 5, the atomizing pump 6, and the suction reflux assembly 9, are mainly located in the middle partition 20, separated from the gas and liquid circuits, avoiding system instability caused by electrical interference. At the same time, the liquid and gas circuits, namely the disinfectant supply and atomization processes, are mainly located in the lower partition 30 and upper partition 10, separated from the electrical circuits, ensuring the safety of the disinfectant during addition and use.

[0052] In summary, this circuit disinfection device achieves a highly efficient and safe disinfection process through the use of novel disinfectants and a precisely designed circuit disinfection structure. Furthermore, the rational layout of the upper partition 10, middle partition 20, and lower partition 30 enables the layered and zoned operation of electricity, gas, and liquid components, making the entire system more efficient and stable, and ensuring the safety of operators when adding disinfectants. This device is suitable for various locations requiring gas circuit disinfection, such as medical equipment and laboratories.

[0053] To further explain, the pressurized liquid supply assembly 5 includes a pressurized air pump 51 and a liquid adding solenoid valve 52;

[0054] The pressurized liquid supply line 4 includes a pressurized sub-line 41 and a liquid supply sub-line 42;

[0055] The disinfectant supply box 3 has a pressurized air port 31 at the top and a liquid supply port 32 at the bottom.

[0056] The booster pump 51 is connected to the booster port 31 of the disinfectant supply box 3 through the booster sub-pipe 41;

[0057] The liquid supply sub-pipeline 42 connects the liquid supply port 32 of the disinfectant supply box 3 and the liquid inlet 11 of the atomizing cup 1, and the liquid supply sub-pipeline 42 is equipped with the liquid adding solenoid valve 52.

[0058] Specifically, when the pressurized liquid supply assembly 5 is working, it first starts the pressurized air pump 51. The pressurized air pump 51 is connected to the pressurized air port 31 of the disinfectant supply tank 3 through the pressurized sub-pipe 41. When the pressurized air pump 51 starts, it generates a certain pressure, which expels the air or gas in the disinfectant supply tank 3, thereby creating a negative pressure or relatively low pressure environment in the disinfectant supply tank 3. This low-pressure environment is key to driving the disinfectant to flow out from the liquid supply port 32 at the bottom of the disinfectant supply tank 3.

[0059] Simultaneously, the liquid-adding solenoid valve 52 opens under the command of the control circuit. The liquid-adding solenoid valve 52 is located on the liquid supply sub-pipeline 42, which connects the liquid supply port 32 of the disinfectant supply tank 3 and the liquid inlet 11 of the atomizing cup 1. When the liquid-adding solenoid valve 52 opens, the disinfectant in the disinfectant supply tank 3 flows into the atomizing cup 1 through the liquid supply sub-pipeline 42 under the combined action of gravity and a low-pressure environment.

[0060] The coordinated operation of the booster pump 51 and the liquid-adding solenoid valve 52 ensures a stable and on-demand supply of disinfectant. This supply method not only ensures that the disinfectant flows continuously and evenly into the atomizing cup 1, but also avoids supply instability caused by pressure fluctuations.

[0061] To further explain, the pressurized liquid supply assembly 5 also includes a gas replenishment solenoid valve 53 and a gas release solenoid valve 54;

[0062] The pressurized liquid supply line 4 also includes a pressure balancing sub-line 43;

[0063] The atomizing cup 1 is also provided with a first pressure relief port 14;

[0064] The balancing pressure sub-pipeline 43 is provided with a vent and two connection ports, and the vent is connected to the outside air.

[0065] One of the connection ports is connected to the first pressure relief port 14 of the atomizing cup 1, and is equipped with the air replenishment solenoid valve 53;

[0066] Another connection port is connected to the booster sub-pipeline 41 and is equipped with the venting solenoid valve 54.

[0067] When the booster pump 51 is continuously started, the pressure inside the disinfectant supply box 3 gradually increases, forming a high-pressure environment; while as the disinfectant in the disinfectant supply box 3 continues to flow out to the atomizing cup 1, the pressure inside the atomizing cup 1 gradually decreases, forming a low-pressure environment.

[0068] Therefore, in order to maintain stable pressure within the disinfectant supply box 3 and the atomizing cup 1, another embodiment is provided, such as... Figure 2 As shown, a gas replenishment solenoid valve 53 and a gas release solenoid valve 54 are added. When the gas replenishment solenoid valve 53 and the gas release solenoid valve 54 start working, when the pressure in the disinfectant supply tank 3 drops below the preset threshold, the gas release solenoid valve 54 opens, allowing excess gas in the disinfectant supply tank 3 to be discharged into the outside air through the vent of the pressure balancing sub-pipeline 43, which helps to quickly reduce the pressure and protect the equipment from high pressure damage.

[0069] Simultaneously, the air replenishment solenoid valve 53 opens, allowing outside air to enter the atomizing cup 1 through the vent of the pressure balancing sub-pipe 43, thereby replenishing the pressure inside the atomizing cup 1. During this process, the air replenishment solenoid valve 53 plays a role in balancing the pressure, preventing insufficient disinfectant supply or equipment damage due to excessive negative pressure.

[0070] Through the coordinated operation of the gas replenishment solenoid valve 53 and the gas release solenoid valve 54, the pressure balance sub-pipeline 43 achieves precise control of the pressure inside the supply box and the atomizing cup 1, ensuring a stable supply of disinfectant.

[0071] To further explain, the suction return assembly 9 includes a suction filter 91 and a suction pump 92;

[0072] The suction filter 91 and the suction pump 92 are installed sequentially on the suction return pipeline 8, and the suction filter 91 is located close to the gas circuit disinfection device 2.

[0073] Specifically, when the compound alcohol disinfectant is atomized in the atomizing cup 1 and disinfection is required, the suction pump 92 is activated. The suction pump 92 generates negative pressure, creating a suction force to draw and move the gas or gas mixture. Under the action of the suction pump 92, the gas formed after the compound alcohol disinfectant is atomized in the atomizing cup 1 is extracted and introduced into the gas circuit disinfection device 2. The disinfectant gas mixes with the disinfectant components in the gas circuit disinfection device 2 and diffuses throughout the circuit, thereby achieving the purpose of disinfection.

[0074] The sterilized gas flows out from the suction return line 8 and returns to the suction return assembly 9. A suction filter 91 is installed on the suction return line 8, near the gas circuit sterilization device 2. The main function of the suction filter 91 is to filter out impurities and particles in the gas, ensuring the cleanliness of the output gas. Simultaneously, it can also adsorb and retain the effective components of the disinfectant to a certain extent, improving the disinfection effect.

[0075] The above process forms a working cycle, where the suction pump 92 continuously draws in atomized gas, the gas circuit disinfection device 2 performs disinfection, and the suction filter 91 filters the gas before outputting clean gas. This cycle can continue until the predetermined disinfection time and effect are achieved.

[0076] To further explain, a liquid level sensor 15 is installed at the liquid inlet 11.

[0077] When the liquid level sensor 15 detects that the atomizing cup 1 contains a preset disinfectant dosage, it sends a message to the control component (not shown in the diagram) to shut down the pressurized liquid supply component 5 and stop the liquid inflow. By combining circuitry and software, this design not only ensures a stable supply of disinfectant but also controls the dosage of the added compound alcohol disinfectant.

[0078] To further clarify, the atomizing cup 1 is made of UPVC material.

[0079] Specifically, UPVC (Unplasticized Polyvinyl Chloride), also known as rigid polyvinyl chloride, is a plastic material with polyvinyl chloride (PVC) as its main component. As is well known, all disinfectants have their synthetic components, and acids, alkalis, strong oxidants, and strong volatiles can negatively impact any disinfection device. Compound alcohol disinfectants are no exception; their stock solution has a pH of 4.01, contains 55.0% ± 5.5% (w / w) of ethanol, and 10.0% ± 1.0% (w / w) of isopropanol. UPVC material, however, can resist the corrosion of strong acids and other chemicals, and will not rust or scale, making it suitable for chemical and other fields.

[0080] To further clarify, the disinfectant is a compound alcohol disinfectant.

[0081] Specifically, the compound alcohol disinfectant is a ready-to-use liquid disinfectant formulated with n-propanol, ethanol, and water for injection. It undergoes multiple processes including disinfection, sterilization, filling, packaging, and irradiation to kill vegetative bacteria, yeast, and some viruses. It leaves no residue and can be applied directly to surfaces that come into direct contact with products.

[0082] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
