[0022] The following describes the preferred embodiments of the present utility model with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.
[0023] Embodiment 1.
[0024] Before introducing the hydrogen peroxide sterilization device provided by the embodiments of the present application, the application scenarios of the hydrogen peroxide sterilization device provided by the embodiments of the present application are introduced as follows:
[0025] The hydrogen peroxide sterilization device provided by the embodiments of the present application is mainly applied in the production process of medical devices, and the packaging containers of medical devices can be sterilized by using the hydrogen peroxide sterilization device provided by this embodiment.
[0026] As Figures 1 to 3 shown, in a first aspect, the embodiments of the present application provide a hydrogen peroxide sterilization device, including:
[0027] An atomization mechanism 10 for atomizing hydrogen peroxide solution;
[0028] A heating mechanism 20 connected to the atomization mechanism 10 for heating the atomized hydrogen peroxide solution into hydrogen peroxide vapor;
[0029] A delivery pipe 30 for delivering hydrogen peroxide vapor;
[0030] Wherein, a preheating mechanism 40 is provided on the delivery pipe 30, and the preheating mechanism 40 is configured to heat the delivery pipe 30 to a temperature higher than that of the hydrogen peroxide vapor.
[0031] Referring to Figure 3 shown, during operation, exemplarily: Place the packaging container in a sealed sterilization chamber, and then deliver the hydrogen peroxide vapor into the sterilization chamber through the delivery pipe 30 to perform sterilization treatment on the packaging container. Since the delivery pipe 30 is preheated, it can effectively prevent the hydrogen peroxide vapor from condensing during transportation, thereby ensuring the sterilization effect.
[0032] Specifically, referring to Figure 1 and Figure 2 shown, before production, the preheating mechanism 40 is arranged on the delivery pipe 30 to preheat the delivery pipe 30 so that the temperature of the delivery pipe 30 is higher than that of the hydrogen peroxide vapor. For example, an electric heating tape, a heating sleeve, etc. can be used. After preheating is completed, the atomization mechanism 10 atomizes the hydrogen peroxide solution into fine droplets (for example, ultrasonic atomization, pneumatic atomization, etc. can be adopted). Subsequently, the heating mechanism 20 is connected to the atomization mechanism 10 to heat the atomized hydrogen peroxide into vaporized hydrogen peroxide vapor, and then the heated hydrogen peroxide vapor is delivered into the sterilization chamber to be sterilized through the delivery pipe 30. In this way, since the delivery pipe 30 is preheated, it can effectively prevent the hydrogen peroxide vapor from condensing during transportation, thereby ensuring the sterilization effect.
[0033] In some embodiments, as Figure 1 and Figure 2As shown, in order to improve the vaporization efficiency of the hydrogen peroxide solution, the heating mechanism 20 includes a sealed chamber 21 and a heater 22 disposed within the sealed chamber 21. The sealed chamber 21 has an inlet 211 connecting to the output end of the atomization mechanism 20, and an outlet 212 connecting to the delivery pipe 30; the heater 22 is located between the communication paths of the inlet 211 and the outlet 212.
[0034] In this embodiment, the atomization mechanism 10 is a micron-level atomizing nozzle, and the atomized particle size of the atomizing nozzle is 10 - 50 microns, which can atomize the hydrogen peroxide solution into finer droplets. The heating mechanism 20 creates a sealed heating space using the sealed chamber 21 and sets the heater 22 (such as an electric heater, a ceramic heater, etc.) therein. After the atomized hydrogen peroxide solution enters the sealed chamber 21 from the output end of the atomization mechanism 10 through the inlet 211, it is directly sprayed onto the heater 22, thereby being quickly and efficiently heated and vaporized into hydrogen peroxide vapor. Finally, the vaporized hydrogen peroxide vapor enters the delivery pipe 30 from the outlet 212 and is transported to the area to be sterilized to ensure the quality of the hydrogen peroxide vapor and improve the sterilization effect.
[0035] In this embodiment, as Figure 1 and Figure 2 shown, in order to avoid local overheating or insufficient vaporization, both the inlet 211 and the outlet 212 are provided on the top wall of the sealed chamber 21, the heater 22 is provided on the bottom wall of the sealed chamber 21, and a partition 23 extending towards the heater 22 is provided on the top wall of the sealed chamber 21. The partition 23 divides the sealed chamber 21 into a U-shaped heating channel connecting the inlet 211 and the outlet 212.
[0036] With this structural design, after the atomized hydrogen peroxide solution enters from the output end of the atomization mechanism 10 through the inlet 211, it can have a longer residence time and a larger contact area with the heater 22 at the bottom before entering the delivery pipe 30. This can effectively prevent the situation where some of the solution directly enters the delivery pipe 30 without being fully vaporized, thereby improving the vaporization efficiency and uniformity, ensuring the complete vaporization of the hydrogen peroxide solution, and ultimately improving the sterilization effect. In addition, since the heater 22 is provided on the bottom wall of the sealed chamber 21, the hydrogen peroxide solution sprayed on the surface of the sealed chamber 21 that does not directly contact the heater 22 can gather and is more likely to come into full contact with the heater 22, further promoting the vaporization process.
[0037] In some embodiments, as Figure 1 and Figure 2As shown, quick-release joints are provided at both the outlet 212 and the inlet 211 of the sealed chamber 21. The design of the quick-release joint (not shown in the figure) enables the sealed chamber 21 to be conveniently and quickly detached from the entire hydrogen peroxide sterilization device, and also facilitates reinstallation, which is convenient for regular cleaning and maintenance.
[0038] In some embodiments, as Figure 1 and Figure 2 shown, a first temperature sensor 50 is provided inside the sealed chamber 21. In this embodiment, the vaporization temperature of the hydrogen peroxide solution is crucial for the sterilization effect: too low a temperature will lead to low vaporization efficiency and affect the sterilization effect; while too high a temperature may cause the decomposition of hydrogen peroxide, not only reducing the sterilization effect, but even posing a safety hazard. By continuously monitoring the temperature change inside the sealed chamber 21 through the first temperature sensor 50, the power of the heater 22 can be adjusted in a timely manner, so as to ensure that the hydrogen peroxide solution is always at the optimal vaporization temperature and achieve an efficient and safe sterilization effect.
[0039] In some embodiments, as Figure 1 and Figure 2 shown, the preheating mechanism 40 is an air heater, and the output end of the air heater is connected to the delivery pipe 30 through a pipeline. In this embodiment, compared with other preheating methods, such as electric heating, using an air heater has a simpler structure and is easier to implement. Only by connecting the output end of the air heater to the delivery pipe 30 through a pipeline can the preheating function be achieved, without complex structural design and control systems. In addition, air as a heat transfer medium has high safety, will not generate open flames, and there will be no safety hazards such as electric leakage, which can reduce the use cost.
[0040] In this embodiment, as Figure 1 and Figure 2 shown, a second temperature sensor 60 is provided on the pipeline connecting the air heater and the delivery pipe 30. In this way, according to the temperature data fed back by the second temperature sensor 60, the power of the air heater can be adjusted to ensure that the preheating temperature is stably within the set optimal range, preventing insufficient preheating or overheating.
[0041] In a second aspect, an embodiment of the present application provides a disinfection system, including the hydrogen peroxide sterilization device according to any one of the embodiments in the first aspect, and the hydrogen peroxide sterilization device is used to generate and transport hydrogen peroxide vapor to the cavity to be sterilized.
[0042] Those skilled in the art can clearly understand that for the convenience and brevity of description, the specific working process of the above-described disinfection system can refer to the corresponding process in the embodiment of the hydrogen peroxide sterilization device described above, and will not be repeated here.
[0043] The hydrogen peroxide sterilization device and disinfection system provided in this embodiment effectively avoid the condensation of steam during transportation by setting a preheating mechanism on the pipeline for transporting hydrogen peroxide steam and preheating it to a temperature higher than that of the hydrogen peroxide steam, ensuring that the steam concentration does not decrease and guaranteeing the stability and reliability of the sterilization effect.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.
