Description

Technical Field

[0001] The invention relates to the field of automatic cleaning of environmental ultraviolet sterilization equipment, in particular to an automatic cleaning system of ultraviolet sterilization equipment. Background Art

[0002] Ultraviolet disinfection equipment is a device that uses ultraviolet (UV) radiation to inactivate or kill bacteria, viruses, fungi and other microorganisms. There are three main types of ultraviolet rays: ultraviolet A (UVA), ultraviolet B (UVB) and ultraviolet C (UVC), among which UVC radiation has a strong bactericidal effect on microorganisms. Ultraviolet disinfection equipment usually uses UVC light sources. This wavelength of ultraviolet light can destroy the nucleic acids and proteins of microorganisms, thereby preventing their growth and reproduction. These devices are widely used in the medical and health fields, food processing industry, water treatment, air purification and other occasions where sterilization is required.

[0003] The existing ultraviolet sterilization equipment usually does not have an automatic cleaning system. Therefore, after the existing ultraviolet sterilization equipment is used for a long time, dirt or dirt will be attached to the outer wall of the ultraviolet lamp, so the brightness of the ultraviolet lamp may be affected, and then the sterilization effect of the ultraviolet lamp will be reduced. It is necessary to manually clean the ultraviolet lamp frequently, and manual cleaning of the ultraviolet lamp may not be complete. Therefore, it is necessary to design an automatic cleaning system to maintain the ultraviolet lamp. The existing cleaning system cannot detect the brightness of the ultraviolet lamp in real time to perform cleaning work, nor can it allow the staff to set a scheduled cleaning cycle to perform scheduled cleaning work. This may cause the ultraviolet sterilization equipment to work for a long time with poor sterilization effect, which will ultimately affect the quality of the required sterilization material. At the same time, the existing cleaning system does not have the effect of remotely checking the internal situation of the ultraviolet sterilization equipment, nor can it remotely start the cleaning work according to the internal situation of the ultraviolet sterilization equipment. Because it does not have this function, even if the cleaning system fails, it is impossible to timely determine the failure of the cleaning system, which makes the maintenance process longer.

[0004] Therefore, in view of the above problems, an automatic cleaning system for ultraviolet disinfection equipment is proposed. Summary of the invention

Through the design of this function, the problem of not being able to check the brightness of the ultraviolet lamp in time is avoided, and there is no need for staff to frequently maintain the ultraviolet sterilization equipment.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned reduction, the present invention provides the following technical solutions: an automatic cleaning system for ultraviolet sterilization equipment, comprising an outer frame and an ultraviolet lamp cleaning mechanism, characterized in that an ultraviolet lamp cleaning mechanism is arranged on the top of the outer frame, the ultraviolet lamp cleaning mechanism comprises a shell, and an intelligently connected scraping mechanism is arranged on the top of the outer frame, and the intelligently connected scraping mechanism comprises a timer.

[0010] Preferably, a wastewater collecting pipe is connected through the outer wall of the outer frame, and a check valve is connected through the outer wall of the wastewater collecting pipe.

[0011] Preferably, a second water pump is connected through the outer wall of the wastewater collecting pipe, and the other end of the wastewater collecting pipe is fixedly connected to a wastewater storage box, and a wastewater extraction port is opened on the top of the wastewater storage box.

[0012] Preferably, a buzzer alarm is arranged on the top of the outer frame, a wireless transceiver is arranged on the top of the outer frame, a camera module is fixedly connected to the inner wall of the outer frame, and a photosensitive sensor is fixedly connected to the inner wall of the outer frame.

[0013] Preferably, the outer wall of the outer frame is fixedly connected to a frame, and the inner wall of the frame is fixedly connected to a second motor.

[0014] Preferably, the output shaft of the second motor is fixedly connected to the second rotating shaft via a coupling, and the outer wall of the second rotating shaft is fixedly connected to the second ball screw.

[0015] Preferably, a second ball nut is mounted on the outer wall of the second ball screw, and an electric push rod is fixedly connected to the outer wall of the second ball nut.

[0016] Preferably, a clamping block is fixedly connected to the outer wall of the electric push rod, and a scraping cotton is fixedly connected to the outer wall of the clamping block.

[0017] According to another aspect of the present invention, there is provided an automatic cleaning system for ultraviolet sterilization equipment, comprising the following steps:

[0018] S1. When cleaning work is required, first use the camera module to observe the working conditions inside the ultraviolet sterilization equipment, and then use the wireless transceiver to remotely start the cleaning work. Similarly, when there is no one on duty, the photosensitive sensor will detect the brightness of the ultraviolet light lamp in the ultraviolet sterilization equipment. If the brightness of the ultraviolet light lamp is low due to being covered with dirt, then the cleaning work will be started through the wireless transceiver. Similarly, when the cleaning time set by the user is reached, the timer will also start the cleaning work through the wireless transceiver.

[0019] S2. Then the second electric valve opens, and the first water pump pumps the cleaning fluid into the high-pressure nozzle. While the high-pressure nozzle is spraying, the first motor is started to drive the first ball screw to rotate, so that the first ball nut drives the high-pressure nozzle to move forward and backward. After the cleaning fluid is evenly sprayed, the second electric valve is closed.

[0020] S3. After the cleaning liquid is evenly sprayed, the electric push rod is used to press the scraping cotton against the surface of the ultraviolet lamp. Then the second motor is used to drive the second ball screw to rotate, so that the second ball nut drives the scraping cotton to wipe the surface of the ultraviolet lamp. This cycle is repeated. If the light sensor still does not detect that the brightness of the ultraviolet lamp is normal, the buzzer alarm will sound an alarm to prompt the staff to perform maintenance. At the same time, the staff can also use the camera module to observe the reason for the failure of the cleaning work.

[0021] S4. After the photosensor detects that the brightness of the ultraviolet lamp is normal, the wiped dirt will fall into the outer frame, and then the first electric valve is opened, and a large amount of liquid is sprayed into the outer frame through the high-pressure nozzle using the first water pump. Then the dirt in the outer frame will be mixed with water to form sewage. At this time, the second water pump can be started to pump the sewage to the wastewater storage tank. At the same time, the wastewater can also be recycled using the wastewater extraction port.

[0022] (III) Beneficial effects

[0023] Compared with the prior art, the present invention provides an automatic cleaning system for ultraviolet sterilization equipment, which has the following beneficial effects:

[0024] When the automatic cleaning system of the ultraviolet sterilization equipment is working, the ultraviolet light lamp cleaning mechanism and the intelligent connection scraping mechanism are set to effectively and automatically clean the ultraviolet sterilization equipment. The automatic cleaning system can perform automatic cleaning through three methods: photosensor, remote start, and timer. First, through the setting of the photosensor, the brightness of the ultraviolet light lamp can be monitored in real time, so that the cleaning work can be started according to the brightness of the ultraviolet light lamp. When the staff remotely observes the situation inside the outer frame through the camera module, if the staff feels that cleaning is needed, the cleaning work can be started through the wireless transceiver. Similarly, the staff can use the timer to set the cleaning cycle. When the timer reaches the cycle that needs cleaning, the cleaning The cleaning work will also start automatically. Through the design of the above-mentioned functions, the automatic cleaning system can conveniently perform automatic cleaning work according to needs, avoiding the problem that the ultraviolet light lamp cannot be cleaned in time. The design of the above functions provides three options. The staff can start the cleaning work at any time. The staff can also set a certain cleaning cycle for regular cleaning work. After the brightness of the ultraviolet light lamp is lower than a certain value, the automatic cleaning system will also start. The design of this function makes the automatic cleaning system more flexible. After the cleaning work is started, the second electric valve will automatically open, and the first water pump will pump the cleaning liquid into the high-pressure nozzle. While the high-pressure nozzle is spraying, the first motor is started to drive the first ball screw to rotate, so that the first ball nut drives the high pressure The nozzle moves back and forth, so that the cleaning liquid can clean the outer wall of the ultraviolet lamp more evenly. After the initial cleaning, a small amount of cleaning liquid will remain on the ultraviolet lamp. Then close the second electric valve, use the electric push rod to make the scraping cotton close to the surface of the ultraviolet lamp, and then use the second motor to drive the second ball screw to rotate, so that the second ball nut drives the scraping cotton to wipe the surface of the ultraviolet lamp. This cycle can be repeated. The design of this function cooperates with the design of the high-pressure nozzle. The residual cleaning liquid can also further allow the scraping cotton to fully scrape the surface of the ultraviolet lamp, so that the cleaning effect is better, and the ultraviolet lamp is further cleaned. At this time, if the photosensor still does not detect that the ultraviolet lamp is on The brightness of the ultraviolet lamp is normal. At this time, the buzzer alarm will sound an alarm to prompt the staff to carry out maintenance. At the same time, the staff can also use the camera module to observe the reason for the failure of the cleaning work. Through the design of this function, the staff can quickly and conveniently find out the fault, simplifying the maintenance process. At the same time, the camera module can not only observe the brightness of the ultraviolet lamp to remotely start the cleaning work, but also quickly find out the fault of the automatic cleaning system. After the photosensitive sensor detects that the brightness of the ultraviolet lamp is normal, the wiped dirt will fall into the outer frame, and then the first electric valve will be opened, and the first water pump will be used to spray a large amount of liquid into the outer frame through the high-pressure nozzle. Then the dirt in the outer frame will be mixed with water into sewage. Through the design of this function,The dirt on the outer wall of the ultraviolet light lamp can be cleaned again, and the remaining dirt can also be mixed into sewage, which is more convenient for cleaning. At this time, the second water pump can be started to pump the sewage to the wastewater storage tank. At the same time, the sewage can be recycled using the wastewater extraction port. Through the design of this function, the sewage can be easily pumped out for recycling. In general, each design of the automatic cleaning system is closely linked and can cooperate with each other. As can be seen from the above, the cleaning system performs three cleaning operations in sequence, and the three cleaning operations cooperate with each other. Therefore, the cleaning effect of the automatic cleaning system is excellent. In addition, the automatic cleaning system effectively improves the automation function of the automatic cleaning system through the setting of photosensitive sensors, timers and camera modules, and reduces the cost of manual regular maintenance.

[0047] According to another aspect of the present invention, there is provided an automatic cleaning system for ultraviolet sterilization equipment, comprising the following steps:

[0048] S1. When cleaning work is required, the camera module 304 is first used to observe the working conditions in the ultraviolet sterilization device, and then the wireless transceiver 303 can be used to remotely start the cleaning work. Similarly, in the case of no one on duty, the photosensitive sensor 305 will detect the brightness of the ultraviolet light lamp in the ultraviolet sterilization device. If the brightness of the ultraviolet light lamp is low due to being covered with dirt, the cleaning work will be started through the wireless transceiver 303. Similarly, when the cleaning time set by the user is reached, the timer 301 will also start the cleaning work through the wireless transceiver 303.

[0049] S2. Then the second electric valve 215 is opened, and the first water pump 209 pumps the cleaning liquid into the high-pressure nozzle 206. While the high-pressure nozzle 206 is spraying, the first motor 202 is started to drive the first ball screw 207 to rotate, so that the first ball nut 205 drives the high-pressure nozzle 206 to move forward and backward. After the cleaning liquid is evenly sprayed, the second electric valve 215 is closed.

[0050] S3. After the cleaning liquid is evenly sprayed, the electric push rod 310 is used to press the scraping cotton 312 against the surface of the ultraviolet lamp. Then, the second motor 307 is used to drive the second ball screw 313 to rotate, so that the second ball nut 309 drives the scraping cotton 312 to wipe the surface of the ultraviolet lamp. This cycle is repeated. If the light sensor 305 still does not detect that the brightness of the ultraviolet lamp is normal, the buzzer alarm 302 will sound an alarm to prompt the staff to perform maintenance. At the same time, the staff can also use the camera module 304 to observe the reason for the failure of the cleaning work.

[0051] S4. After the light sensor 305 detects that the brightness of the ultraviolet lamp is normal, the wiped dirt will fall into the outer frame 1, and then the first electric valve 211 is opened, and a large amount of liquid is sprayed into the outer frame 1 through the high-pressure nozzle 206 by using the first water pump 209. Then the dirt in the outer frame 1 will be mixed with water to form sewage. At this time, the second water pump 220 can be started to pump the sewage to the wastewater storage tank 221. At the same time, the wastewater can also be recycled using the wastewater extraction port 222.

[0052] Workflow and working principle:

[0053] The automatic cleaning system is designed with three methods to start the cleaning work. First, the staff can use the camera module 304 to observe the working conditions in the ultraviolet sterilization equipment, and then use the wireless transceiver 303 to remotely start the cleaning work. Similarly, in the case of no one on duty, the photosensitive sensor 305 will detect the brightness of the ultraviolet light lamp in the ultraviolet sterilization equipment. If the brightness of the ultraviolet light lamp is low due to being covered with dirt, the cleaning work will be started through the wireless transceiver 303. Similarly, the user can set the cleaning cycle by himself through the timer 301. When the set cleaning time is reached, the timer 301 will also start the cleaning through the wireless transceiver 303. After the cleaning work is started by the above method, the second electric valve 215 will be opened first, and the first water pump 209 will pump the cleaning liquid from the cleaning liquid tank 216 and the shunt pipe 214 to the high-pressure nozzle 206. The high-pressure nozzle 206 will use the cleaning liquid to rinse and spray the surface of the ultraviolet light lamp. While spraying the cleaning liquid, the cleaning liquid can be further attached to or cleaned inside the ultraviolet device through the multiple side spray holes 207 opened on the outer wall of the high-pressure nozzle 206. Then, the first motor 202 is started to drive the first ball screw 207 to rotate, so that the first ball nut 205 drives the high-pressure nozzle 206 to move forward. After the cleaning liquid is evenly sprayed, the second electric valve 215 will be closed, and then the electric push rod 310 will be used to make the scraping cotton 312 close to the surface of the ultraviolet light lamp, and then the second motor 307 will drive the second shaft 308 and the second ball screw 313 to rotate, so that the second ball nut 309 drives the scraping cotton 312 to wipe the surface of the ultraviolet light lamp, and this cycle is repeated. If the light sensor 305 still does not detect that the brightness of the ultraviolet light lamp is normal, the buzzer alarm 302 will sound an alarm to prompt the staff to perform maintenance. At the same time, the staff can also use the camera module 304 to observe the reason for the failure of the cleaning work. After the photosensitive sensor 305 detects that the brightness of the ultraviolet lamp is normal, the wiped dirt will fall into the outer frame 1, and then the first electric valve 211 is opened, and the first water pump 209 is used to pump water from the water tank 212 and the pipe connection port 213, and then a large amount of liquid will be sprayed into the outer frame 1 through the high-pressure nozzle 206. Then the dirt in the outer frame 1 will be mixed with water into sewage, and the ultraviolet lamp can be further cleaned. At this time, the second water pump 220 can be started to pump the sewage to the wastewater storage tank 221, and the wastewater can also be recycled using the wastewater extraction port 222. This is the working process of the automatic cleaning system of the ultraviolet sterilization equipment.

If the brightness of the ultraviolet light lamp is low due to being covered with dirt, the cleaning work will be started through the wireless transceiver (303). Similarly, when the cleaning time set by the user is reached, the timer (301) will also start the cleaning work through the wireless transceiver (303). S2. Then, the second electric valve (215) is opened, and the first water pump (209) pumps the cleaning liquid into the high-pressure nozzle (206). While the high-pressure nozzle (206) is spraying, the first motor (202) is started to drive the first ball screw (207) to rotate, so that the first ball nut (205) drives the high-pressure nozzle (206) to move forward and backward. After the cleaning liquid is evenly sprayed, the second electric valve (215) is closed. S3. After the cleaning liquid is evenly sprayed, the electric push rod (310) is used to place the scraping cotton (312) close to the surface of the ultraviolet lamp, and then the second motor (307) is used to drive the second ball screw (313) to rotate, so that the second ball nut (309) drives the scraping cotton (312) to wipe the surface of the ultraviolet lamp. This cycle is repeated. If the light sensor (305) still fails to detect that the brightness of the ultraviolet lamp is normal, the buzzer alarm (302) will sound an alarm to prompt the staff to perform maintenance. At the same time, the staff can also use the camera module (304) to observe the reason for the failure of the cleaning work. S4. After the light sensor (305) detects that the brightness of the ultraviolet light is normal, the wiped dirt will fall into the outer frame (1). Then, the first electric valve (211) is opened, and a large amount of liquid is sprayed into the outer frame (1) through the high-pressure nozzle (206) by the first water pump (209). Then, the dirt in the outer frame (1) is mixed with the water to form sewage. At this time, the second water pump (220) is started to pump the sewage into the wastewater storage tank (221). At the same time, the sewage can also be recycled by using the wastewater extraction port (222).
