Description

Technical Field

[0001] The invention belongs to the field of unconventional treatment of biological wastes, and in particular relates to a portable disinfection garbage can based on microwave disinfection and inactivation. Background Art

[0002] Trash cans are widely used in every corner of society, such as homes, offices, conference rooms, communities, hospitals, etc., to handle daily waste. In a period when the whole society attaches great importance to environmental protection and pays special attention to health, especially at the critical moment of fighting the new pneumonia, a large number of medical wastes such as discarded masks, tissues, protective clothing, etc. with bacteria and viruses will be generated. Whether it is a single medical waste or a trash can collected and put into it, it is a medical hazardous waste and pollution source, which can easily cause huge hidden dangers of transmission under suitable environment. In order to block the spread of medical waste viruses including the new pneumonia from the source as much as possible, the current scientific and technological forces and the capabilities of enterprises are applied to provide the society with a new portable medical waste trash can with disinfection and inactivation functions that is convenient, safe, and acceptable to the public. Such products can be used in homes, offices, conference rooms, communities, hospitals and other places, and can also eliminate the hidden dangers of epidemic transmission of a large number of discarded masks, tissues, etc. generated during the epidemic period, and completely block the spread of the epidemic from the source.

[0003] Medical waste refers to waste that is directly or indirectly infectious, toxic, and otherwise hazardous and that is generated by medical and health institutions in related activities. If improperly disposed of, it will pose a threat to human health and life safety. Hospitals are the main places where medical waste is generated, and a large amount of medical waste such as gloves, gauze, cotton balls, urine cups, paper towels, and masks are generated every day. The material characteristics and appearance of hazardous waste in hospitals are relatively complex. The garbage that is continuously added to the trash can brings in a large number of germs and microorganisms. The moist environment in the trash can provides a good and complex environment for germs and microorganisms. Pathogens and microorganisms penetrate outward from the gaps in the trash can or spread outward at the moment the lid is opened, endangering public safety. In addition, during the collection, transportation, storage, and transportation process within the hospital, there is an inevitable risk of increased germ leakage. Especially in the current period of fighting against the new pneumonia, many toxic medical wastes are hazardous wastes, and they need to be used, disposed of, collected, and managed with great caution. At present, the main methods of disposing of medical waste are incineration and non-incineration. The treatment facilities are relatively large, very fixed, and operated by dedicated personnel. They also need to be collected before being treated. They cannot generate medical waste at any time and eliminate viruses at any time, which easily creates the risk of virus transmission and spread.

[0004] In order to deal with the breeding and leakage of viruses and harmful microorganisms that may exist in medical waste from the source, the existing technology needs to be further developed and improved. Summary of the invention

[0005] In view of the various deficiencies of the prior art, in order to solve the above problems, a portable disinfection trash can based on microwave disinfection and inactivation is now proposed. To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A portable disinfection trash can based on microwave disinfection and inactivation comprises a trash can body capable of reflecting microwaves, the trash can body being provided with a trash inlet and a trash outlet, the trash can body being sealed, and a microwave emission structure for disinfection and inactivation being also provided inside the trash can body.

[0007] Furthermore, the microwave emitting structure includes a microwave tube, and a microwave tube installation opening is provided on the trash can body corresponding to the microwave tube.

[0008] Furthermore, the number of the microwave tubes is 1 to 4.

[0009] Furthermore, the microwave tube is arranged on the top of the trash can body.

[0010] Furthermore, the microwave emitting structure also includes a microwave radiation window for compressing garbage, the microwave radiation window is connected to a microwave radiation window support rod that can move up and down, and the bottom end of the microwave radiation window support rod is connected to the microwave radiation window.

[0011] Furthermore, a temperature sensor is provided at the bottom of the microwave radiation window.

[0012] Furthermore, the microwave radiation window is a mica radiation window.

[0013] Furthermore, the microwave radiation window has a thickness greater than 5 mm.

[0014] Furthermore, the garbage inlet is located on the side of the garbage bin body, and a first movable baffle is provided at the garbage inlet.

[0015] Furthermore, the garbage outlet is located at the bottom surface of the garbage can body, and a second movable baffle is provided at the garbage outlet.

[0016] Beneficial effects:

[0017] In the closed space formed by the microwave emission structure and the trash can, physical conditions of high temperature and strong microwave field for killing bacteria are established, so as to achieve timely virus inactivation and bacterial sterilization of domestic and medical waste in the trash can. The garbage is continuously compressed by the microwave radiation window. As the garbage is compressed and dense, the temperature field required for virus inactivation and bacterial sterilization after the garbage is exposed to microwaves is relatively stable, and the temperature after heating will not be uneven due to large density differences, and the temperature can be maintained for a long time. At the same time, the air and air circulation inside the garbage are greatly reduced due to the compression of the garbage, thereby avoiding the problem of burning of the garbage after microwave heating, eliminating safety hazards.

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0023] like Figure 1 and Figure 2A portable disinfection trash can based on microwave disinfection and inactivation is shown, comprising a trash can body 1 which can reflect microwaves internally, the trash can body 1 is provided with a trash inlet and a trash outlet, the trash can body 1 is sealed, and a microwave emission structure for disinfection and inactivation is also provided inside the trash can body 1. According to the requirements of conventional biological disinfection at 100°C and the characteristics of microwaves acting on substances with non-contact, penetration, selectivity, etc., preferably, the trash can is made of metal material, which can prevent microwaves from leaking out, thereby establishing high temperature and microwave strong field physical conditions for killing bacteria in the closed space formed by the microwave emission structure and the trash can, and realizing timely virus inactivation and bacterial sterilization of domestic and medical waste in the trash can.

[0024] Preferably, the microwave emission structure includes a microwave tube, and a microwave tube installation port 2 is provided on the trash can body 1 corresponding to the microwave tube. The microwave tube emits microwaves to form a temperature field and a microwave field required for virus inactivation and bacterial sterilization in the trash can body 1. The microwave tube installation port 2 ensures that the microwave tube enters the interior of the trash can body in a sealed state to prevent microwave leakage. Preferably, the microwave tube adopts an industrial 1kW magnetron with a frequency of 2450MHz. The microwave tube is connected through a conventional wave conversion and is controlled by a temperature sensor during operation. When the material reaches the required temperature of 100 degrees Celsius, the microwave tube stops emitting microwaves.

[0025] Preferably, 1-4 microwave tubes are provided. Preferably, 2 microwave tubes are provided, which are respectively arranged on both sides of the microwave radiation window support rod 4, and are applied to the garbage can for instant sterilization, and can quickly reach the predetermined microwave magnetic field and temperature conditions, saving costs while accelerating the sterilization efficiency. The minimum distance between the microwave tube and the material is 20 cm, and the garbage bin body and the microwave radiation window below the microwave tube form a microwave action cavity. Preferably, the microwave action cavity is 20 cm wide, 36 cm long, and 70 cm deep, and the maximum thickness of the material loading is 50 cm. That is, when a 1kW magnetron is used, the microwave tube processing conditions with a frequency set to 2450MHz, and the microwave action cavity is set to be 20 cm wide, 36 cm long, and 70 cm deep, the best sterilization efficiency can be achieved.

[0026] Preferably, the microwave tube is arranged on the top of the trash can body 1, so as to facilitate the separation of the trash and the microwave emission structure, so that the microwave tube does not hinder the entry and discharge of the trash, and does not affect other microwave emission structures, such as the realization of the function of the microwave radiation window 3 to compress the trash.

[0027] like Figure 2As shown, the microwave emission structure also includes a microwave radiation window 3 for compressing garbage, and the microwave radiation window 3 is connected to a microwave radiation window support rod 4 that can move up and down, and the bottom end of the microwave radiation window support rod 4 is connected to the microwave radiation window 3. The microwave radiation window support rod 4 is moved up and down to drive the microwave radiation window 3 to move up to the top of the garbage can body 1 before the garbage is put in, and the microwave radiation window support rod 4 is moved down after the garbage is put in, and the microwave radiation window 3 is moved down to the bottom of the garbage can body 1. With the downward movement, the garbage is continuously compressed by the microwave radiation window 3. Since the garbage is compressed and dense, the temperature field required for virus inactivation and bacterial sterilization after the garbage is subjected to microwave action is relatively stable, and the temperature after heating will not be uneven due to the large difference in density, and the temperature can be maintained for a long time. At the same time, since the garbage is compressed, the air and air circulation inside the garbage are greatly reduced, thereby avoiding the problem of burning of the garbage after microwave heating, eliminating safety hazards. The size of the microwave radiation window 3 is set to correspond to the size of the cross-section of the trash can body 1 to ensure that the microwave radiation window 3 will not cause the microwave tube to be contaminated by garbage during the garbage compression process, thereby reducing the microwave efficiency.

[0028] Preferably, a temperature sensor is also provided at the bottom of the microwave radiation window 3. The temperature sensor is used to monitor the temperature change inside the garbage and provide real-time feedback to the operator or control system. The microwave radiation window support rod 4 is a hollow structure, and the signal line of the temperature sensor is led to the external controller through the hollow structure of the microwave radiation window support rod 4. Here, the temperature sensor measures the material temperature, and when it reaches the set 100 degrees Celsius, the control system shuts down the microwave tube. By shutting down and starting the microwave tube through the control system, the material temperature is maintained at the set temperature of 100 degrees Celsius and the required processing time of 10 minutes, and the disinfection and sterilization of the processed material can be completed.

[0029] Preferably, the microwave radiation window 3 is a mica radiation window. Mica has good heat resistance, stable chemical properties, and no absorption of microwave radiation, and can better transmit microwave radiation to the waste to be processed. On the other hand, the mica radiation window has good mechanical strength and can compact the processed materials well.

[0030] Preferably, in order to compact the processed materials and ensure the mechanical strength of the mica radiation window, the thickness of the microwave radiation window 3 is greater than 5 mm. At the same time, the larger thickness can ensure the rigidity of the microwave radiation window 3, so that the microwave radiation window 3 will not be deformed during the garbage compression process.

[0031] Preferably, the garbage inlet is located on the side of the garbage can body 1, and a first movable baffle 5 is provided at the garbage inlet. The garbage inlet is provided on the side of the garbage can body 1 to ensure the normal operation of the microwave transmitting mechanism, and because the microwave radiation window 3 is pulled to the top of the garbage can body 1, throwing garbage into the bin from the side will not cause contamination to the microwave probe of the microwave tube. A first movable baffle 5 is provided at the garbage inlet to seal the garbage inlet, ensuring that the barrel body is in a closed state during the microwave sterilization process. Preferably, the first movable baffle 5 is provided as a pull-out baffle to ensure the sealing effect.

[0032] Preferably, the garbage outlet is located at the bottom surface of the garbage can body 1, and a second movable baffle 6 is provided at the garbage outlet. The garbage outlet is arranged at the bottom surface of the garbage can body 1, which will not affect the normal operation of the microwave emission mechanism and is convenient for dumping garbage. A second movable baffle 6 is provided at the garbage outlet to seal the garbage outlet, ensuring that the barrel body is in a closed state during the microwave sterilization process. Preferably, the second movable baffle 6 is arranged as a pull-out baffle, which is convenient for dumping garbage and ensures a sealing effect.

[0033] A method for using a portable disinfection trash can based on microwave disinfection and inactivation, comprising the following steps:

[0034] S1, slowly lift the microwave radiation window support rod 4 to the top plate of the trash can body 1, the top of the microwave radiation window support rod 4 is connected to a lifting mechanism, and the lifting mechanism can be manual or electric;

[0035] S2, opening the first movable baffle 5 at the garbage entrance, and the garbage enters the garbage bin body 1 from the garbage entrance;

[0036] S3, slowly press down the microwave radiation window support rod 4 to the bottom of the garbage can body 1, and close the first movable baffle 5 at the garbage entrance;

[0037] S4, turn on the power switch, set the required treatment temperature and time in the control system, the preferred sterilization conditions are treatment temperature of 100°C and treatment time of 10 minutes, after ensuring that the trash can body 1 is in a sealed state as a whole, press the start button, the microwave tube emits microwaves through the microwave tube installation port 2, and acts on the garbage squeezed by the microwave radiation window 3, the temperature sensor monitors the temperature change of the garbage in the trash can body 1, and feeds back to the control system in real time, the control system controls the microwave tube to shut down and start, stops the microwave work after reaching the predetermined temperature and the predetermined time, and starts the microwave work when it is lower than the set temperature, thereby maintaining the material at the set temperature, because the material heats up very quickly during the microwave treatment (1-2 minutes), so the maintenance time of the set temperature is approximately the treatment time, so as to keep the treated material fully disinfected and inactivated;

[0038] S5. After sterilization, the power switch can be turned off, and the next batch of garbage can be put in again before the extrusion and microwave radiation treatment process is performed until the garbage in the garbage can body 1 reaches the predetermined maximum load. Preferably, the maximum thickness of the material loading is 50 cm. The garbage can body 1 is transferred to the top of the harmless garbage recycling area, and the second movable baffle 6 at the garbage outlet is opened to discharge the sterilized garbage from the bottom.

[0039] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
