Description

Technical Field

[0001] The present invention relates to the field of sterilization devices, in particular to a cavity-type normal-pressure low-temperature plasma disinfection and sterilization device. Background Art

[0002] Plasma disinfection uses a bipolar plasma electrostatic field to decompose and destroy negatively charged bacteria, polarize and adsorb dust, and then combines components such as drug-impregnated activated carbon, electrostatic nets, and photocatalytic devices for secondary sterilization and filtration. The treated clean air circulates rapidly in large quantities, keeping the controlled environment at the "sterile clean room" standard.

[0003] In the prior art, a Chinese patent document with publication number CN115138149A proposes a plasma disinfection and sterilization air purification device, which solves the problem that after the existing plasma air purification device is used for a long time, dust in the air remains on the surface of the filter screen, the dust will clog the filter screen, reduce the efficiency of air purification, and also reduce the filtering effect of the filter screen, so that a small amount of dust is discharged with the purified air, reducing the air purification effect. However, in actual application, there is still a problem that after the cavity-type normal-pressure low-temperature plasma disinfection and sterilization device is working, a small amount of dust will accumulate on the bottom surface of the cavity. Because the cavity is mostly deep and a storage rack is provided in the cavity that is not easy to clean, the bottom surface of the cavity is rarely cleaned. However, the dust accumulation on the bottom surface of the cavity will have a certain impact on the sterilization of objects, resulting in a reduced sterilization effect of the objects. Therefore, we disclose a cavity-type normal-pressure low-temperature plasma disinfection and sterilization device to meet the demand for easy cleaning of dust at the bottom end of the cavity.

[0017] (3) Beneficial effects

[0018] Compared with the existing technology, the present invention provides a cavity-type atmospheric pressure low-temperature plasma disinfection and sterilization device, which has the following beneficial effects:

[0019] 1. This cavity-type normal-pressure low-temperature plasma disinfection and sterilization device drives the cleaning roller to rotate at the bottom of the sterilization chamber through the connecting block, cleans the dust generated after sterilization at the bottom of the sterilization chamber, thereby ensuring that there is no dust in the sterilization chamber when the object is sterilized next time, thereby improving the sterilization effect of the object. After cleaning the dust, the cleaning roller can be rinsed with water from the outlet pipe on the outer wall of the cleaning roller to ensure that the outer wall of the cleaning roller is in a clean state, thereby ensuring the cleaning effect of the cleaning roller on the bottom surface of the sterilization chamber.

[0020] 2. The chamber-type normal-pressure low-temperature plasma disinfection and sterilization device drives the half gear and the first gear to rotate through the second motor, so that the half gear drives the turntable to rotate through the rack and the connecting rod, so that the turntable drives the reel to rotate the winding rope through the belt group, so that the rope pulls the baffle, so that the baffle rotates along the sterilization chamber, so that the baffle opens the partition between the cleaning tank and the sterilization chamber, so that the cleaning roller can enter the cleaning tank from the sterilization chamber to clean the cleaning roller, thereby ensuring the long-term use effect of the cleaning roller. After that, the reel releases the reeling of the baffle, so that the baffle falls, separating the cleaning tank and the sterilization chamber, preventing water in the cleaning tank from splashing into the sterilization chamber, ensuring the cleaning results in the sterilization chamber, and preventing the sterilization chamber from being contaminated by water when the cleaning roller is cleaning.

[0021] 3. The cavity-type normal-pressure low-temperature plasma disinfection and sterilization device drives the second gear to rotate when the first gear rotates, so that the cleaning roller rotates, so that the outer wall of the cleaning roller can be washed by the water outlet pipe, thereby ensuring the cleaning effect of the cleaning roller. When the cleaning roller enters the cleaning tank, the extrusion strip is squeezed upward, so that the extrusion strip drives the scraper cover to move upward along the brush through the connecting plate, so that the extrusion strip can squeeze out the excess water absorbed by the cleaning roller, thereby avoiding excessive water content of the cleaning roller, affecting the cleaning of the sterilization chamber by the cleaning roller, and also ensuring that the scraper cover does not affect the cleaning of the cleaning roller by the brush. When the roller is cleaning, it rotates under the drive of the first gear, and at the same time, the dust on the surface will be brushed off by the brush after being sprayed by the water outlet pipe, and then the excess water will be squeezed out by the squeezing bar, so that the cleaning effect of the cleaning roller is better, which is beneficial to the long-term use of the cleaning roller. When the cleaning roller moves out of the inner cavity of the cleaning tank, the squeezing bar will lose the squeezing of the cleaning roller and will fall under the action of its own weight and the spring, and then the scraper cover is driven to move downward, so that the scraper cover scrapes off the dust on the outer wall of the cleaning roller by the brush, completing the self-cleaning of the brush, thereby ensuring that the brush has a better cleaning effect on the cleaning roller, which is beneficial to the long-term use of the device.

[0033] The working principle of the present invention is as follows: when in use, after the first motor 3 is started, the connecting block 5 is driven to move through the lead screw 4. The user places the object to be sterilized in the sterilization chamber 29. After the sterilization is completed and the object is taken out, the first motor 3 is started, and the cleaning roller 8 is driven to rotate at the bottom end of the sterilization chamber 29 through the connecting block 5 to clean the dust generated after sterilization at the bottom end of the sterilization chamber 29, thereby ensuring that there is no dust in the sterilization chamber 29 when the object is sterilized next time, thereby improving the sterilization effect of the object.

When the cleaning roller 8 enters the cleaning tank 7, the squeezing strip 27 is squeezed upward, so that the squeezing strip 27 drives the scraper cover 23 to move upward along the brush 22 through the connecting plate 24, so that the squeezing strip 27 can squeeze out the excess water absorbed by the cleaning roller 8, thereby avoiding the water content of the cleaning roller 8 being too high, affecting the cleaning of the sterilization chamber 29 by the cleaning roller 8, and also ensuring that the scraper cover 23 does not affect the cleaning of the cleaning roller 8 by the brush 22, and the cleaning roller 8 enters the cleaning tank 7. During cleaning, it rotates driven by the first gear 19, and at the same time, the dust on the surface is brushed off by the brush 22 after being sprayed by the water outlet pipe 9, and then the excess water is squeezed out by the squeezing bar 27, so that the cleaning effect of the cleaning roller 8 is better, which is beneficial to the long-term use of the cleaning roller 8. When the cleaning roller 8 moves out of the inner cavity of the cleaning tank 7, the squeezing bar 27 will lose the squeezing of the cleaning roller 8 and it will fall under the action of its own weight and the spring 26, and then the scraper cover 23 is driven to move downward, so that the scraper cover 23 scrapes off the dust on the outer wall of the cleaning roller 8 by the brush 22, completing the self-cleaning of the brush 22, thereby ensuring that the brush 22 has a better cleaning effect on the cleaning roller 8.

[0036] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
