Description

Technical Field

[0001] The utility model relates to the technical field of sterilizers, in particular to a hydrogen peroxide sterilizer capable of expanding the sterilization range. Background Art

[0002] Hydrogen peroxide sterilizer is a strong oxidant. It uses its strong oxidizing property to effectively kill bacteria and fungi such as Escherichia coli, Staphylococcus aureus, and Candida albicans. It is mainly used for sterilization of sanitary ware, general object surfaces, food production environments, breeding environments, food tools and equipment, etc. Vaporized hydrogen peroxide is a very important space sterilization method. Vaporized hydrogen peroxide sterilization is widely used because of its easy degradation and no residue. Vaporized hydrogen peroxide sterilization technology is to heat 35% hydrogen peroxide solution to above 130°C, instantly vaporize it to form gaseous hydrogen peroxide, and diffuse it into a confined space. Atomized hydrogen peroxide uses a hydrogen peroxide solution with a concentration of 5%~12%, which contains <50ppm of silver. Ions and other chemical substances are generated by the atomizer to produce 8-10 micron particles, which diffuse in the space through irregular movement. After aeration, the atomized hydrogen peroxide remains in the sterilization space and naturally decomposes into oxygen and water vapor. No active residue removal or catalytic decomposition system is required. During the use of the hydrogen peroxide sterilizer, the placement of the hydrogen peroxide sterilizer has a great influence on the sterilization range of hydrogen peroxide. When using it, you need to pay strict attention to the placement angle of the sterilizer to avoid the air outlet facing the obstruction, which will reduce the sterilization range. However, due to the power supply and environmental influences, the sterilizer cannot be placed in the middle of the environment to be sterilized, which causes uneven distribution of hydrogen peroxide gas and affects the overall sterilization effect.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-7 The utility model provides a technical solution: a hydrogen peroxide sterilizer capable of expanding the sterilization range.

[0031] Embodiment 1: This embodiment discloses: an outer box body 1, a liquid storage tank 2 and an atomizer 3 are fixedly arranged inside the outer box body 1, and a liquid suction tube 4 is connected between the liquid storage tank 2 and the atomizer 3, one end of an injection tube 5 is connected to the side surface of the liquid storage tank 2, and the other end of the injection tube 5 passes through the outer surface of the outer box body 1, and a dynamic switching mechanism is arranged inside the outer box body 1 to increase the sterilization range in one direction and maintain the sterilization effect in other directions;

[0032] The dynamic switching mechanism includes: a lead-out box 6, a discharge port 7 is provided on the side surface of the lead-out box 6, a motor 8 is fixedly installed on the inner bottom surface of the outer box body 1, and a linkage rod 9 is fixedly connected to the upper end of the output shaft of the motor 8, an air outlet 10 is provided on the outer surface of the outer box body 1, a rotating connecting ring 11 is installed on the lower surface of the lead-out box 6, and an exhaust hole 12 is provided at one end of the connecting ring 11, and a connecting hose 13 is connected between the lower end of the exhaust hole 12 and the liquid outlet of the atomizer 3, and the connecting ring 11 is fixedly connected to the liquid storage tank 2;

[0033] The linkage rod 9 is hexagonal in design, and the linkage rod 9 is slidably connected to the export box 6;

[0034] When in use, first move the outer box body 1 to a suitable position and connect an external power supply. At this time, start the motor 8 according to the placement position of the sterilizer. The motor 8 drives the export box 6 to rotate through the linkage rod 9, so that the discharge port 7 can face the air outlet 10 on one side. At this time, a sufficient amount of liquid hydrogen peroxide is injected into the liquid storage tank 2 through the injection pipe 5, and the atomizer 3 is started to inhale the liquid hydrogen peroxide through the suction pipe 4. The atomizer 3 changes the liquid hydrogen peroxide into a gaseous state and injects it into the export box 6 through the exhaust hole 12 on the surface of the connecting ring 11 connected to the other end of the connecting hose 13. The export box 6 discharges the gaseous hydrogen peroxide to the air outlet 10 through the discharge port 7 and outputs it to the external environment. The flow rate at the air outlet 10 facing the discharge port 7 is faster and larger than that of the air outlet 10 in other directions due to the flow direction of the gas output from the discharge port 7. The air outlets 10 in other directions can also output gaseous hydrogen peroxide because they are interconnected, thereby ensuring the sterilization effect in all directions.

[0035] Embodiment 2: This embodiment is disclosed on the basis of embodiment 1: a directional output mechanism is provided inside the outer box 1 for directional output of gas and preventing excessive pressure inside the outlet box 6;

[0036] The directional output mechanism includes: a mounting ring 14, the mounting ring 14 is rotatably mounted on the upper surface of the export box 6, and one end of a hydraulic rod 15 is fixedly arranged on the upper surface of the mounting ring 14, and the hydraulic rod 15 is fixedly mounted on the upper end of the outer box body 1, the inner surface of the outer box body 1 is provided with a first cavity 16 and a second cavity 17, and a one-way valve 18 is arranged between the adjacent first cavity 16 and the second cavity 17, the lower surface of the first cavity 16 is penetrated by a closing plate 19, and the closing plate 19 is fixedly connected to the lower surface of the export box 6, a piston plate 20 is arranged inside the outer box body 1, and a press switch 21 is arranged above the piston plate 20;

[0037] The side surfaces of the first cavity 16 and the second cavity 17 are in contact with the outer surface of the outlet box 6, and the two adjacent first cavities 16 are connected to each other. The height of the closing plate 19 is greater than the height of the first cavity 16, and the outer surface of the closing plate 19 is in contact with the inner surface of the first cavity 16.

[0038] The piston plate 20 is connected to the export box 6 by sliding friction, and a spring is connected between the piston plate 20 and the export box 6. The push switch 21 is fixedly connected to the export box 6, and the push switch 21 is located in the middle of the upper end of the export box 6;

[0039] When it is necessary to output gaseous hydrogen peroxide in one direction, the hydraulic rod 15 is started, and the hydraulic rod 15 drives the export box 6 to slide upward through the mounting ring 14. As the export box 6 slides upward, the discharge port 7 is disconnected from the first cavity 16 and connected to the second cavity 17. When the discharge port 7 outputs gaseous hydrogen peroxide to the outside, the gaseous hydrogen peroxide is injected into the second cavity 17 and injected into the corresponding first cavity 16 below through the one-way valve 18. At this time, since the closing plate 19 slides upward with the export box 6 to close the end of the first cavity 16 facing the inside of the outer box body 1, the gaseous hydrogen peroxide in the first cavity 16 can only be discharged through the opposite gas outlet 10 to achieve directional output;

[0040] When the air outlet 10 is blocked due to external factors, as the internal pressure of the outlet box 6 increases, the piston plate 20 slides up under the pressure and presses the press switch 21. The press switch 21 sends an electrical signal to stop the atomizer 3 from working, thereby preventing the atomizer 3 from being damaged due to excessive output pressure.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
