Description

Technical Field

[0001] This invention relates to the fields of environment and public health, and in particular to an online automatic purification and recycling device and method for face masks. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Face masks are the most common measure to block the spread of exhaled pathogens and prevent respiratory infections. The use of personal protective equipment such as face masks (e.g., ordinary medical surgical masks, N95 masks) is increasing year by year in countries and regions around the world, becoming an essential item in modern life. However, most masks purchased and used are disposable, discarded after one or more uses. Even if individuals wash or disinfect used masks, it is impossible to completely remove the contaminants accumulated on their surface. Used masks easily carry allergens and pathogens, and the disposal of these used masks easily creates environmental problems, affecting public health and human health. Furthermore, the large-scale production of disposable masks consumes a significant amount of global production resources. In addition, in the event of a public health emergency, the production capacity of disposable masks may not be able to keep up with demand.

[0004] While existing technologies include disinfection equipment for masks, these are only simple disinfection methods and are not suitable for the collection, disinfection, and reuse of large quantities of masks. Summary of the Invention

[0005] In view of the shortcomings of existing technologies, the purpose of this invention is to provide an online automatic purification and recycling device for disposable masks, which solves the problems of resource waste, environmental pollution, and difficulty in reuse of existing disposable masks.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0011] The aforementioned equipment features a support platform that supports the recycled masks and can stain the masks for microorganisms. The microbial fluorescence detection mechanism in the detection component can determine the number of microorganisms in the mask and then send the information to the control unit. The control unit controls the operation of the disinfection component based on the information, and further achieves cleaning and drying. The entire system makes full use of the internal space of the first shell to achieve disinfection, cleaning and drying of the masks. The disinfection and purification are controlled according to the amount of microorganisms, saving energy while recycling masks.

[0012] The online automatic purification mask recycling device described above, wherein the disinfection component includes an ultraviolet sterilization unit and at least one plasma sterilization unit disposed along the first shell;

[0013] This forms a tiered, multi-stage purification unit. The control unit adjusts the activation frequency of disinfection components based on the amount of microorganisms present. If the microbial population is low, only the ultraviolet sterilization unit is activated; if the microbial population is high, the plasma sterilization unit is activated. In some designs, the plasma sterilization unit is divided into a first-stage plasma sterilization zone and a second-stage plasma sterilization zone. The main difference between the first-stage and second-stage plasma sterilization zones lies in the number of low-temperature plasma generators; the second stage has more generators than the first.

[0014] The plasma sterilization unit is connected to the cleaning component.

[0015] The online automatic purification mask recycling device described above includes a cleaning component comprising a water jet nozzle installed in the first housing;

[0016] The drying component includes a drying mechanism, which includes an air outlet fixed to the first housing to blow hot air onto the washed mask.

[0017] As described above, in an online automatic purification mask recycling device, the first shell contains a conduit area below the cleaning component to store the tubing, mainly because the tubing of the plasma sterilization unit needs to occupy the space of the conduit area.

[0018] The bottom of the first housing is provided with a track, and the side of the lifting mechanism is provided with a roller. The roller is an electric roller and is connected to the control unit. The control unit controls the roller to achieve reciprocating motion.

[0019] As described above, an online automatic purification mask recycling device has a second shell arranged around the first shell, with a space between the second shell and the first shell for storing masks.

[0020] As described above, in an online automatic purification mask recycling device, a third shell is fixed to the periphery of the second shell, and the third shell is provided with a mask retrieval port communicating with the second shell. The mask conveying mechanism is fixed between the mask retrieval port and the outlet of the first shell.

[0021] As described above, in an online automatic purification mask recycling device, a base is fixed to the bottom of the second shell, and a portion of the disinfection components are installed inside the base.

[0025] The control unit is connected to the operation display screen, which is located on the head shell, enabling human-machine interaction.

[0026] Secondly, the present invention also provides a method for operating an online automatic purification mask recycling device, comprising the following:

[0027] The recycled masks enter the first shell through the inlet, and the support platform is raised to the dyeing part by the lifting mechanism;

[0028] The dye atomizing nozzle at the dyeing component sprays dye toward the recycled mask to fluorescently dye the mask;

[0029] The support platform moves the mask down to the detection component, where the microbial fluorescence detection mechanism performs microbial fluorescence detection on the mask and sends the detected information to the control unit. The control unit controls the opening of the disinfection component based on the detected amount of microorganisms.

[0030] The support platform moves the mask down to the disinfection unit, where the disinfection unit disinfects the mask.

[0031] The support platform moves the mask to the other side of the vertical partition and lifts it to the cleaning unit, where the cleaning unit cleans the mask.

[0032] The support platform moves the mask upwards, and the drying components dry the mask.

[0033] The beneficial effects of the present invention are as follows:

[0034] 1) The present invention uses the above-mentioned equipment to support the recycled masks on the support platform, which can stain the masks for microorganisms. The microbial fluorescence detection mechanism in the detection component can judge the number of microorganisms in the mask and then send the information to the control unit. The control unit controls the operation of the disinfection component according to the information, and further realizes cleaning and drying. The whole system makes full use of the internal space of the first shell to achieve disinfection, cleaning and drying of the mask, realize the recycling of the mask, and control the disinfection and purification according to the amount of microorganisms, which is more intelligent and plays a role in saving resources.

[0035] 2) In addition to the ultraviolet sterilization unit, the disinfection component of this invention is also equipped with several plasma sterilization units, which further enables the control of the activation of different disinfection units according to the amount of microorganisms detected, so as to fully ensure the disinfection effect on the mask.

[0036] 3) This invention, through the setting of a plasma sterilization unit, can not only generate low-temperature plasma in the air using air as a gas source, but also remove dyes and chemical pollutants (such as semi-volatile organic compounds) on the surface of the mask within seconds, while also efficiently removing the microorganisms and allergens on the surface of the mask; the unit can also generate low-temperature plasma underwater (flame jet length 3-5cm), and at the same time produce active water with a sterilization effect. The active oxygen substances (such as OH free radicals and monatomic oxygen) contained in the active water can inactivate microorganisms and be used for cleaning masks in the subsequent cleaning area.

[0037] 4) In this invention, the cleaning component can clean the mask with active sterile water generated by the plasma sterilization unit, or other water sources can be used to clean the mask.

[0038] 5) The second shell of the present invention covers the first shell, the top of the first shell is provided with a head shell, and the first shell is provided with a vertical partition plate. The overall structure is reasonably designed and makes full use of the internal space of the first shell to realize the detection and disinfection of microbial contamination on the surface of the mask, which greatly improves the utilization efficiency of the mask and solves the problems of resource waste, environmental pollution and difficulty in reuse of existing disposable masks.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0054] As described in the background section, there is a problem in the existing technology of not having corresponding equipment for recycling masks. In order to solve the above-mentioned technical problem, the present invention proposes an online automatic purification mask recycling device.

[0055] Example 1

[0056] In a typical embodiment of the present invention, reference is made to Figure 1 As shown, an online automatic purification and recycling device for face masks includes:

[0057] The first shell has a vertical partition plate 15 inside. The first shell has an inlet 3 and an outlet on both sides of the vertical partition plate 15. The bottom of the first shell has a support platform 9 connected to a lifting mechanism. The lifting mechanism moves on both sides of the vertical partition plate 15. The first shell 21 has a dyeing component, a detection component and a disinfection component arranged from top to bottom on the inlet side. The first shell 21 has a cleaning component and a drying component arranged from bottom to top on the outlet side.

[0058] The dyeing component includes a dye atomizing nozzle 41 installed in the dyeing zone 4 of the first shell to spray dye onto the recovered mask, thereby staining the microorganisms. The dye atomizing nozzle 41 is connected to a spray can, which contains dye and water. Specifically, green fluorescent nucleic acid dye, red fluorescent nucleic acid dye, and sodium iodide are used as dyes. During operation, the dye and water are mixed and the liquid is atomized and sprayed onto the surface of the mask through the dye atomizing nozzle. After dyeing, the active bacteria are green and the inactivated microorganisms are red.

[0059] The detection component includes a microbial fluorescence detection mechanism fixed to the first shell, which is an existing mechanism;

[0060] The lifting mechanism, dyeing component, detection component, disinfection component, cleaning component, and drying component are each individually connected to the control unit.

[0061] The first shell is cylindrical. On one side of the first shell, there are a dyeing area 4, a detection area 6, an ultraviolet sterilization area 7, and a plasma sterilization area 8. On the other side of the first shell, there are a mask transfer area 20, a drying area 22, a cleaning area 23, and a conduit area 24.

[0062] In addition, horizontal partitions are installed between the staining area and the testing area, between the testing area and the ultraviolet sterilization area, and between the cleaning area and the catheter area. The horizontal partitions are connected to a flip motor, which is connected to a control mechanism, thereby controlling the flipping of the horizontal partitions to facilitate the lifting mechanism to drive the support platform to move up and down.

[0063] It should be explained that the vertical partition does not reach the bottom of the first shell, leaving room for the horizontal movement of the lifting mechanism and the support platform.

[0064] The detection components include a fluorescence excitation block 61 and a fluorescence signal detector 62 fixed to the detection area 6 of the first shell. The fluorescence excitation block 61 uses a broadband ultraviolet fluorescence excitation block, a narrow-band blue light fluorescence excitation block, or a broadband green light fluorescence excitation block as a laser emission source. The fluorescence signal detector is a prior art technology.

[0065] In this embodiment, the disinfection component includes an ultraviolet sterilization unit and a plasma sterilization unit arranged sequentially from top to bottom along the first shell. The plasma sterilization unit is divided into a first-stage plasma sterilization zone and a second-stage plasma sterilization zone, both of which are low-temperature plasma sterilization units. The arrangement of the plasma generators is referenced. Figure 6 As shown, its specific structural design reference Figure 7 As shown;

[0066] The low-temperature plasma sterilization unit is connected to the cleaning components.

[0067] Specifically, the ultraviolet sterilization unit includes several existing ultraviolet sterilization lamps 71 fixed to the ultraviolet sterilization zone 7 of the first shell, and multiple layers of ultraviolet sterilization zones 7 can be set, see reference. Figure 5 As shown, each UV sterilization zone 7 can specifically use 4 UV sterilization lamps, which are distributed in parallel along the four sides of the UV sterilization zone to perform the first-level disinfection of microorganisms on the surface of the mask.

[0068] refer to Figure 2 and Figure 6 As shown, the low-temperature plasma sterilization unit includes a low-temperature plasma generator 81 fixed at the low-temperature plasma sterilization zone 8. The low-temperature plasma generator 81 is connected to a low-temperature plasma generator air supply pipe 82. The low-temperature plasma generator air supply pipe 82 is provided in multiple locations, and the multiple low-temperature plasma generator air supply pipes 82 are bent toward the plasma sterilization zone 8. The low-temperature plasma generator 81 is provided at the front end of the low-temperature plasma generator air supply pipe 82.

[0069] refer to Figure 7As shown, the low-temperature plasma generator includes a pipeline with a top switch 811 at one end and a circumferential ring around the pipeline with an air inlet and outlet 812. A plasma generation zone 813 is located inside the other end of the pipeline. The plasma generation zone 813 includes a brass rod 8131 and a quartz tube 8132. The quartz tube 8132 is located inside the brass rod 8131, and plasma 814 is generated through the brass rod 8131 and the quartz tube 8132.

[0070] The low-temperature plasma generator 81 outputs 12-24V and generates low-temperature plasma using air as the generator gas source. It uses left and right brass rods and a quartz tube as positive and negative electrodes, generating plasma by breaking down the air. The plasma jet length in the air is 5-10cm. The low-temperature plasma can remove dyes while sterilizing and efficiently remove chemical contaminants (such as semi-volatile organic compounds) from the surface of masks.

[0071] Preferably, in addition to generating plasma flames in the air, the low-temperature plasma generator can also generate plasma underwater, simultaneously producing activated water with disinfection effects. The active oxygen substances (such as OH free radicals and monatomic oxygen) contained in this activated water can inactivate bacteria and are used for cleaning masks in the subsequent cleaning area. Furthermore, the active oxygen substances in the water will decompose and be removed from the air in a very short time (sub-seconds), without causing harm to the human body.

[0072] This forms a tiered, multi-stage purification unit. The control unit adjusts the activation frequency of disinfection components based on the amount of microorganisms present. If the microbial population is low, only the ultraviolet sterilization unit is activated; if the microbial population is high, the plasma sterilization unit is activated. The plasma sterilization unit is divided into a first-stage plasma sterilization zone and a second-stage plasma sterilization zone. The main difference between the first-stage and second-stage plasma sterilization zones lies in the number of low-temperature plasma generators; the second stage has more generators than the first.

[0073] In addition, refer to Figure 3 As shown, the cleaning component includes a water jet nozzle 231 installed on the first housing. The water jet nozzle is connected to the low-temperature plasma sterilization unit, so that the active sterile water generated by the low-temperature plasma sterilization zone is used to clean the mask, remove residual adhering contaminants, and perform deep cleaning on the mask surface; of course, the water jet nozzle can also use other water sources to perform deep cleaning on the mask.

[0074] Understandably, the water jet nozzle 231 is arranged in the cleaning zone 23 of the first shell, and the cleaning zone 23 is at the same height as the ultraviolet sterilization zone 7 on the other side.

[0075] The drying component includes a drying mechanism, which includes an air outlet fixed to the drying area 22 of the first shell to blow hot air onto the cleaned mask. The drying mechanism dries the thoroughly disinfected and cleaned mask, keeping it dry and flat. Understandably, the drying mechanism adopts an existing drying mechanism.

[0076] The first shell contains a conduit area 24 below the cleaning components to store pipelines, mainly the pipelines of the plasma sterilization unit, such as the low-temperature plasma generator gas supply pipe 82, which require space in the conduit area.

[0077] The bottom of the first housing is provided with a track 102, which may be a groove. The side of the lifting mechanism is provided with a roller 103, which is an electric roller. The electric roller is connected to the control unit, and the control unit controls the roller to achieve reciprocating motion.

[0078] In this embodiment, reference Figure 8 As shown, the lifting mechanism is an electric telescopic sleeve 10, and the support platform 10 is hollow, so that the support platform can drive the mask to move vertically and horizontally.

[0079] In some examples, the electrically telescopic sleeve 10 includes multiple pipe fittings 101. The outer wall of each pipe fitting 101 is provided with a rack 104. The rack engages with a gear fixed to the next pipe fitting. The rotation of the gear 105 drives the pipe fitting 101 to extend or retract, thereby achieving vertical movement.

[0080] A second shell 16 is disposed around the periphery of the first shell 21. A space is provided between the second shell 16 and the first shell 21 to store masks. A mask conveying mechanism is fixed inside the second shell and can extend into the outlet of the first shell. A third shell is fixed around the periphery of the second shell. The third shell is provided with a mask retrieval port communicating with the second shell. The mask conveying mechanism is fixed between the mask retrieval port and the outlet of the first shell, and the mask conveying mechanism transports the dried masks to the mask retrieval port 19.

[0081] The third shell 5 is fixed to the periphery of the second shell, and the mask retrieval opening of the second shell extends to the third shell.

[0082] The second and third shells are also cylindrical. A storage area 25 is formed between the second shell and the first shell. The storage area 25 is used to store clean masks. Some masks can be placed in the storage area. Both the third shell and the second shell are provided with a common opening for taking out and putting in masks. A door can be installed at the opening for taking out and putting in masks. In some examples, the diameter of the first shell is 1 / 2 the diameter of the second shell, and the diameter of the second shell is 1 / 2 the diameter of the third shell.

[0083] In this embodiment, a mask transfer area 20 is formed above the drying component inside the first shell. The mask conveying mechanism is a robotic arm. The robotic arm 17 is fixed to the inner wall of the second shell by a robotic arm. The robotic arm can rotate and extend to transfer the disinfected and purified masks from the mask transfer area 20 to the end storage area 18.

[0084] refer to Figure 9 As shown, the robotic arm includes a robotic arm 171, which is a telescopic rod. The robotic arm is connected to a robotic gripper via a robotic arm rotating wheel 172. The robotic arm 171 can control the extension and retraction of the robotic arm, thereby enabling the robotic arm to move in the vertical direction. The robotic arm rotating wheel 172 can control the rotation of the robotic gripper, thereby enabling the robotic arm to move in the horizontal direction.

[0085] The mechanical gripper includes a connecting rod that is connected to the rotating wheel 172 of the robotic arm. One end of the connecting rod is equipped with a clamp telescopic control rod 174 and two robotic arm clamps 175. The clamp telescopic control rod is T-shaped. The clamp telescopic rod 174 is connected to the robotic arm clamps 175 through a clamp telescopic rotation component 173 (such as a pin). When the clamp telescopic control rod 174 extends or retracts, the robotic arm clamps 175 can be opened and clamped by the control of the clamp telescopic rotation component 173, thereby realizing the placement and retrieval of masks.

[0086] In addition, a base 11 is fixed at the bottom of the second shell. Some disinfection components are installed inside the base, mainly referring to the air pump 12. The air pump provides the necessary gas raw materials to the low-temperature plasma generator through the low-temperature plasma generator gas supply pipe 82. There is a pump exhaust port 13 on the side of the base.

[0087] It should be added that the base 11 is a trapezoidal cylinder, and the base 11 is equipped with several casters. The casters are connected to the control unit and are electric casters 14. The control unit controls the casters to drive the entire device to move, and it can be moved to a designated position as required.

[0088] The third housing is equipped with an obstacle detection switch, which is connected to the control unit.

[0089] The first shell has a head cover at the top, and the control unit is fixed to the head cover 2. The head cover has an arc-shaped top 1 and covers the entrance 3. The first shell has a switch cover at the entrance 3. The switch cover is connected to the first shell through a rotating shaft. The rotating shaft is connected to a motor. An existing induction switch is installed at the switch cover. The induction switch is connected to the control unit and the motor separately. When the user approaches the induction switch, the induction switch sends a message to the control unit. The control unit controls the motor to drive the rotating shaft to rotate, thereby opening the switch cover. After opening, the user puts the mask into the entrance.

[0090] refer to Figure 4As shown, the control unit is connected to the operation display screen 27, which displays relevant detection information. The operation display screen 27 is equipped with a voice recognition button 26. The operation display screen is located on the head shell 2. Users can view the mask pollution detection results and disinfection and purification effects through the operation display screen 27, and can also activate the voice recognition button 26 to control the movement of the device, the recycling and retrieval of the mask, etc.

[0091] It is easy to understand that the control unit is a PLC controller or other type of controller. The control unit is equipped with an existing signal processing feature extraction module and decoder, and has a voice recognition module. Through the voice recognition module, the control unit can recognize the user's voice commands. The control unit is connected to a camera, and through the camera and the signal processing feature extraction module, the location of the user can be automatically identified and tracked, thereby realizing human-machine interaction.

[0092] In addition, the control unit can wirelessly transmit data with mobile phones or other wireless devices via Bluetooth or other wireless communication facilities.

[0093] The device provided in this embodiment supports the recycled masks on a support platform and can stain the masks for microorganisms. The microbial fluorescence detection mechanism in the detection component can determine the number of microorganisms in the mask and then send information to the control unit. The control unit controls the operation of the disinfection component based on the information, and further realizes cleaning and drying. The whole device makes full use of the internal space of the first shell to achieve disinfection, cleaning and drying of the mask. The whole device controls the opening of each disinfection component according to the amount of microorganisms to disinfect and purify the mask. While realizing the recycling of masks, it also saves energy.

[0094] The mask recycling equipment provided in this embodiment has a total cost of approximately RMB 0.55 when operating at the highest level of disinfection and purification. This includes RMB 0.50 for dyeing, RMB 0.024 for ultraviolet sterilization, RMB 0.000168 for plasma sterilization, and RMB 0.025 for the drying component. The energy consumption of other components is negligible. Under these operating conditions and costs, assuming 20 masks need to be disinfected, the recycling cost per mask is less than RMB 0.0275. Moreover, the more masks disinfected and purified, the lower the recycling cost per mask. Compared to the cost of producing masks (approximately RMB 0.11 per mask), this significantly reduces the resource and labor costs required for mask production. Furthermore, mask recycling greatly reduces the environmental space occupation and pollution caused by discarded masks, possessing broad market prospects globally. Moreover, mask disinfection also prevents pathogens, allergens, and chemical pollutants carried on used masks from contaminating the environment.

[0095] Example 2

[0096] This embodiment provides a working method for an online automatic purification mask recycling device, referring to... Figure 1 As shown, it includes the following:

[0097] Used disposable medical surgical masks enter the first shell through the entrance, and the support platform is raised to the dyeing part by the lifting mechanism;

[0098] The dye atomizing nozzles at the dyeing component spray dye toward the recycled masks to stain microorganisms;

[0099] The support platform moves the mask down to the detection component. The microbial fluorescence detection mechanism performs microbial fluorescence detection on the mask to obtain microbial quantity information and sends the detected information to the control unit. The control unit controls the activation of each level of disinfection components based on the detected microbial quantity information. It determines whether to activate only the ultraviolet lamp or the low-temperature plasma sterilization unit based on the amount of microorganisms.

[0100] The support platform moves the mask down to the disinfection component, which then disinfects the mask. When the low-temperature plasma sterilization unit is turned on, it can remove some of the residual dye from the mask.

[0101] The support platform moves the mask to the other side of the vertical partition and lifts it to the cleaning unit, where it cleans the mask, removes contaminants, and provides further cleaning.

[0102] The support platform continues to move the mask upwards, and the drying components dry the mask.

[0103] After drying, the robotic arm transfers the dried masks to the end storage area 18, or places the masks in the storage area 25;

[0104] Users can remove the mask through the mask removal port 19 or the removal / putting-in port.

[0105] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
