Description

Technical Field

[0001] This utility model belongs to the field of disinfection technology, specifically, it relates to an ozone-based disinfection and sterilization cabinet. Background Technology

[0002] Ozone disinfection cabinets, as a highly efficient and environmentally friendly disinfection device, have been widely used in various fields such as medical, food, and pharmaceutical in recent years. They utilize the strong oxidizing properties of ozone to rapidly oxidize and destroy the cell walls and cell membranes of microorganisms such as bacteria and viruses, thereby achieving disinfection and sterilization. However, ozone also poses certain hazards to the human body, especially a strong irritant effect on the respiratory tract. Therefore, after the ozone disinfection cabinet has finished working, the door should only be opened after the ozone has naturally reduced to prevent operators from inhaling ozone and suffering poisoning. However, because the ozone concentration produced inside the disinfection cabinet is often high during operation, the waiting time is relatively long, making it inconvenient for the repeated use of the ozone disinfection cabinet.

[0024] See Figure 1-3 As shown, an ozone-based disinfection and sterilization cabinet includes a cabinet body 1. The cabinet body 1 has an openable and closable sealed door 2. Inside the cabinet body 1 are an ozone generator 3 capable of producing a large amount of ozone gas, a heating pipe 4 capable of raising the temperature inside the cabinet body 1, and a storage mechanism 5 for placing objects to be disinfected and sterilized. In this embodiment, the ozone generator 3 is located on the inner bottom surface of the cabinet body 1, the heating pipe 4 is located at the top of the cabinet body 1, and the storage mechanism 5 is located between the ozone generator 3 and the heating pipe 4, and is situated between the side walls of the inner cavity of the cabinet body 1. A ventilation system 6, an exhaust system 7, and a recirculating air system 8 are provided on the outer side wall of the cabinet body 1, and the ventilation system 6, the exhaust system 7, and the recirculating air system 8 are respectively connected to the inner cavity of the cabinet body 1.

[0025] Furthermore, in this embodiment, an isolation ventilation plate 9 is provided above the ozone generator 3. The isolation ventilation plate 9 is detachably fixed inside the cabinet 1. The isolation ventilation plate 9 ensures that the ozone generated by the ozone generator 3 can enter the inner cavity above the cabinet 1, while effectively preventing objects placed in the storage mechanism 5 from falling and damaging the ozone generator 3.

[0026] Furthermore, in this embodiment, the heating tube 4 is provided in three sets, but not limited to three sets. It can also be set to other numbers, as long as the requirements are met. During installation, the three sets of heating tubes 4 are arranged at intervals and are all fixed to the top of the cabinet 1.

[0027] Furthermore, in this embodiment, the storage mechanism 5 is provided in three sets, but not limited to three sets; it can also be set to other numbers, as long as the requirements are met. Each set of the storage mechanism 5 includes a pair of U-shaped support seats 501 and a placement rack 502. During installation, the pair of U-shaped support seats 501 are respectively located at the left and right ends of the inner cavity of the cabinet 1. At this time, the U-shaped openings of the pair of U-shaped support seats 501 are opposite each other, and the placement rack 502 passes through the U-shaped openings of the pair of U-shaped support seats 501, and the placement rack 502 can be pulled out from between the pair of U-shaped support seats 501.

[0028] Furthermore, in this embodiment, the ventilation system 6 includes a ventilation pipe 601, one end of which is connected to the inner cavity of the cabinet 1, and a first electromagnetic on / off valve 602 is connected in series on the ventilation pipe 601 to control the on / off of the ventilation pipe 601; and a filter screen 603 is provided at the pipe opening at the other end of the ventilation pipe 601, which can effectively intercept pollutants such as dust, particles, pollen, bacteria, and viruses in the air, thereby effectively reducing the secondary pollution of objects placed on the storage mechanism 5 by these substances entering the cabinet 1.

[0029] Furthermore, in this embodiment, the exhaust system 7 includes an exhaust duct 701, one end of which is connected to the inner cavity of the cabinet 1. A second electromagnetic on / off valve 702, a fan 703, and an ozone reduction device 704 are connected in series on the exhaust duct 701. During operation, the second electromagnetic on / off valve 702 controls the opening and closing of the exhaust duct 701. The fan 703 drives the airflow in the cabinet 1 to enter the exhaust duct 701, and after passing through the ozone reduction device 704, it is discharged. The ozone entering the duct is reduced by the ozone reduction device 704.

[0030] Furthermore, in this embodiment, the circulating air system 8 includes a circulation pipe 801, both ends of which are connected to the inner cavity of the cabinet 1, and an air pump 802 is connected in series on the circulation pipe 801. During installation, one end of the circulation pipe 801 is located at the upper end of the cabinet 1, and the other end is located at the lower end of the cabinet 1. During operation, the air pump 802 drives the airflow inside the cabinet 1 to circulate through the circulation pipe 801.

[0031] Furthermore, in this embodiment, a protective cover 10 is provided on the outer side wall of the cabinet 1, and the ventilation system 6, the exhaust system 7 and the circulating air system 8 are all located inside the protective cover 10; at this time, the other ends of the ventilation pipe 601 and the exhaust pipe 701 are both inserted inside the protective cover 10 and are connected to the outside.

[0032] Furthermore, in this embodiment, an ozone concentration sensor 11 is also provided inside the cabinet 1 to monitor the ozone concentration inside the cabinet 1.

[0033] Furthermore, in this embodiment, a pad 12 is provided at each of the four top corners of the bottom surface of the cabinet 1. The main function of the pad 12 is to increase the stability of the cabinet 1 and reduce the noise when the disinfection and sterilization cabinet is working. A handle 13 is provided on the sealed door 2 to facilitate the opening and closing of the sealed door 2.

[0034] The working principle of this utility model is as follows:

[0035] During disinfection and sterilization, first place the objects to be disinfected and sterilized on the rack 502 and then close the sealing door 2; then start the equipment. At this time, the air pump 802 starts, driving the airflow inside the cabinet 1 to circulate through the circulation pipe 801. At the same time, the ozone generator 3 starts, generating ozone gas, and under the action of the air pump 802, the ozone is quickly and evenly distributed to the cabinet 1, so as to achieve the most uniform disinfection in the disinfection cabinet and improve the disinfection and sterilization effect.

[0036] After disinfection and sterilization are completed, the air pump 802 stops running. At the same time, the first electromagnetic on / off valve 602 and the second electromagnetic on / off valve 702 open, and the fan 703 starts. At this time, driven by the fan 703, the ozone in the cabinet 1 enters the exhaust pipe 701, and is discharged after being reduced by the ozone reduction device 704. Meanwhile, the outside air enters the cabinet 1 through the ventilation pipe 601, thereby achieving rapid removal of ozone in the cabinet 1.

[0037] When the ozone concentration sensor 11 detects that the ozone concentration inside the cabinet 1 is lower than the set value, the first electromagnetic shut-off valve 602, the second electromagnetic shut-off valve 702, and the fan 703 are closed. At the same time, the heating element 4 and the air pump 802 are started. The heating element 4 heats the temperature inside the cabinet 1 to between 60 and 70 degrees Celsius, reducing the ozone remaining inside the cabinet 1 and on the objects to be sterilized. The air pump 802 also circulates the heat within the cabinet 1, distributing it evenly and improving heating efficiency while reducing energy consumption. Once the set heating time has elapsed, the sterilization process is complete.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
