Description

Technical Field

[0001] This invention relates to the field of spray disinfection and sterilization devices, and in particular to a spray disinfection and sterilization device for use in the air detection chamber of a medical infrared thermal imager. Background Technology

[0002] Infrared thermal imaging technology is a product of the combination of medical technology, infrared camera technology, and computer multimedia technology. It is an imaging device that records the thermal field of the human body. The human body is a natural biological heat source. Due to differences in anatomical structure, tissue metabolism, blood circulation, and nerve state, different parts of the body have different temperatures, forming different thermal fields. The infrared thermal imager is located in a chamber. During or after the examination, the chamber needs to be disinfected using a spray disinfection and sterilization device.

[0003] Existing spray disinfection and sterilization devices have the following problems during operation:

[0004] 1. During the spray disinfection process, the large space inside the cabin can lead to incomplete disinfection, and some dead corners inside the cabin are difficult to disinfect, resulting in poor disinfection and sterilization effect.

[0005] 2. After spray disinfection and sterilization, dirt easily accumulates inside the machine. With prolonged use, the outer casing of the machine is not easy to disassemble, making it difficult to clean the inside of the machine, which can easily affect the quality of subsequent spray disinfection and sterilization.

[0006] 3. During the spray disinfection process, the humidity inside the chamber is likely to be high, which can lead to a poor internal environment, affecting the inspection results and causing poor air quality inside the chamber. Summary of the Invention

[0007] The purpose of this invention is to provide a spray disinfection and sterilization device for the air in the detection chamber of a medical infrared thermal imager, which improves the disinfection and sterilization effect, enhances the inspection effect, and reduces the difficulty of cleaning.

The first atomizing plate is movably mounted in the spray chamber through a movable shaft.

[0011] Among them, the ultrasonic atomizing sheet can not only spray for disinfection and sterilization, but the bubbles it generates can also clean items.

[0012] The adjustment assembly includes a movable ball, a nozzle, and a first rotating shaft. The movable ball is movably disposed on one side of the mounting head and is in communication with the mounting head. The nozzle is disposed on one side of the movable ball. The first rotating shaft is movably disposed on one side of the machine body and is connected to the movable ball.

[0013] The cleaning assembly includes a second atomizing plate and a second rotating shaft. The second atomizing plate is movably disposed in the transfer chamber, one end of the second rotating shaft is movably disposed on one side of the machine body, and the other end of the second rotating shaft is connected to the second atomizing plate.

[0014] The drive assembly includes a drive structure, a third rotating shaft, a first pulley system, a second pulley system, and a third pulley system. The drive structure is located on the top of the body. One end of the third rotating shaft is movably mounted on one side of the body, and the other end of the third rotating shaft is connected to a first atomizing plate. One end of the second rotating shaft is connected to the output end of the drive structure. The second rotating shaft and the third rotating shaft are driven by the first pulley system, and the third rotating shaft and the first rotating shaft are driven by the second pulley system.

[0015] The drive structure includes a drive motor and a reducer. The drive motor is connected to the reducer, and the reducer is connected to the second rotating shaft. The first pulley system, the second pulley system, and the third pulley system each include two pulleys and a transmission belt.

[0016] The fresh air drying assembly includes a ventilation plate, a fan, a heater, and an air duct. A ventilation slot is provided on one side of the body. The ventilation plate is connected to a movable shaft. The fan is located on one side of the ventilation plate. The ventilation plate and the fan are located inside the ventilation slot. The heater is located on one side of the ventilation slot. One end of the air duct is connected to the ventilation slot, and the other end of the air duct is connected to the transfer chamber. The heater is located on one side of the fan.

[0017] The heater and the air duct openings are located on one side of the ventilation plate.

[0018] The anti-backflow assembly includes a fourth rotating shaft, an adjusting shaft, a fixed block, and a blocking block. One end of the fourth rotating shaft is movably disposed on one side of the machine body, and the adjusting shaft is movably disposed on one side of the water supply pipe and located inside the water supply pipe. The other end of the fourth rotating shaft is connected to one end of the adjusting shaft. The fixed block is fixedly disposed on the inner wall of the water supply pipe. The blocking block is connected to the adjusting shaft and is located above the fixed block. Both the fixed block and the blocking block are semi-cylindrical structures. The fourth rotating shaft and the second rotating shaft are driven by a third pulley system.

[0019] The fixed block and the blocking block each occupy half of the space in the water pipe.

[0020] The feature is that a sewage pipe is provided inside the machine body, and one end of the sewage pipe is connected to the transfer chamber.

[0021] The machine body is equipped with a fresh air duct, one end of which is connected to a ventilation slot.

[0022] The present invention has the following beneficial effects:

[0023] 1. The present invention links the first atomizing plate and the second atomizing plate together through a driving structure. The first atomizing plate and the second atomizing plate have different specifications. The bubbles produced by the second atomizing plate are larger. After the second atomizing plate cleans, the first atomizing plate cleans again. This can achieve graded cleaning, reduce cleaning difficulty, and improve cleaning effect.

[0024] 2. This invention, after spray disinfection and sterilization, activates the drive structure to rotate the second rotating shaft 90°, causing the second atomizing plate to rotate so that its spray output portion is aligned with the transfer chamber. The remaining disinfectant in the spray chamber then impacts the second atomizing plate, and the spray generated by the second atomizing plate impacts the wall of the transfer chamber, thus cleaning the transfer chamber. The drive structure can also rotate the first atomizing plate via the third rotating shaft. When the first atomizing plate rotates 180°, its output end faces the opposite direction to the original direction, towards the spray chamber. The spray generated by the first atomizing plate impacts the wall of the spray chamber, cleaning the spray chamber, reducing cleaning difficulty, and improving the quality of subsequent spray disinfection and sterilization.

[0025] 3. This invention utilizes a drive structure to rotate the second rotating shaft by no more than 60°, allowing for clockwise or counterclockwise rotation. The second rotating shaft, through a first pulley system, drives the third rotating shaft, which in turn drives the first rotating shaft through the second pulley system. The first rotating shaft causes the movable ball to rotate, indirectly adjusting the nozzle angle and widening the spray angle, thus improving the comprehensiveness of disinfection and ensuring that some dead corners within the chamber are disinfected, thereby enhancing the disinfection and sterilization effect.

[0026] 4. This invention improves the air quality inside the cabin by starting a fan during the disinfection and sterilization process, introducing fresh air into the ventilation duct through a fresh air pipe, and then outputting the fresh air into the cabin through the fan.

[0027] 5. This invention regulates the humidity inside the chamber and improves the environmental quality by activating the heater and fan to bring in fresh air and output hot air during the cleaning process, after the spray disinfection and sterilization.

[0028] 6. This invention regulates the humidity inside the chamber and improves the environmental quality by activating the heater and fan to bring in fresh air and output hot air during the cleaning process, after the spray disinfection and sterilization.

[0029] 7. The present invention rotates the movable ball through the first rotating shaft, which drives the nozzle to rotate to the maximum angle, so that the nozzle can be retracted into the machine body, protecting the nozzle from damage and improving the service life of the device.

[0030] 8. The present invention improves the synchronization of the device by using a drive structure and a pulley system to drive the various components to switch and cooperate at different working stages.

[0031] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] In the description of this invention, it should be understood that the terms "upper," "middle," "outer," "inner," etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0046] like Figure 1-9 As shown, this embodiment is a spray disinfection and sterilization device for the air in the detection chamber of a medical infrared thermal imager, including a body 110, an ultrasonic spray assembly 120, an adjustment assembly 130, a cleaning assembly 140, a fresh air drying assembly 150, an anti-backflow assembly 160, and a drive assembly 170.

[0047] The ultrasonic spray assembly 120, adjustment assembly 130, cleaning assembly 140, fresh air drying assembly 150, and anti-backflow assembly 160 are all located inside the body 110. The drive assembly 170 is located on the top of the body 110. The drive assembly 170 is connected to the ultrasonic spray assembly 120, adjustment assembly 130, cleaning assembly 140, and anti-backflow assembly 160. The ultrasonic spray assembly 120 is located between the adjustment assembly 130 and the cleaning assembly 140. The fresh air drying assembly 150 is located below the ultrasonic spray assembly 120.

[0048] The ultrasonic spray assembly 120 includes a water storage chamber 1201, a transfer chamber 1202, a spray chamber 1203, a mounting head 1204, a first atomizing plate 1205, a water supply pipe 1206, and a water pump 1207. The water storage chamber 1201 is located inside the body 110. The transfer chamber 1202 is connected to the water storage chamber 1201 through the water supply pipe 1206. The water pump 1207 is mounted on the water supply pipe 1206. The spray chamber 1203 is connected to the transfer chamber 1202. The mounting head 1204 is connected to the spray chamber 1203. The first atomizing plate 1205 is movably mounted in the spray chamber 1203 through a movable shaft 1208.

[0049] During operation, disinfectant water is stored in the water storage chamber 1201. Driven by the water pump 1207, the disinfectant water is input from the water storage chamber 1201 to the transfer chamber 1202, and then from the transfer chamber 1202 into the spray chamber 1203. In the spray chamber 1203, the disinfectant water hits the first atomizing plate 1205, and the disinfectant water is atomized. Then it enters the mounting head 1204 and is sprayed out through the nozzle 1302.

[0050] The adjustment assembly 130 includes a movable ball 1301, a nozzle 1302, and a first rotating shaft 1303. The movable ball 1301 is movably disposed on one side of the mounting head 1204 and is connected to the mounting head 1204. The nozzle 1302 is disposed on one side of the movable ball 1301. The first rotating shaft 1303 is movably disposed on one side of the machine body 110 and is connected to the movable ball 1301.

[0051] During operation, by activating the drive structure 1701, the drive structure 1701 drives the second rotating shaft 1402 to rotate by no more than 60°, which can rotate clockwise or counterclockwise. The second rotating shaft 1402 drives the third rotating shaft 1702 to rotate through the first pulley system 1703. The third rotating shaft 1702 drives the first rotating shaft 1303 to rotate through the second pulley system 1704. The first rotating shaft 1303 causes the movable ball 1301 to rotate, indirectly adjusting the angle of the spray head 1302, so that the spray angle of the spray head 1302 is wider, improving the comprehensiveness of disinfection, so that some dead corners in the cabin can be disinfected, and improving the disinfection and sterilization effect.

[0052] Furthermore, the first rotating shaft 1303 causes the movable ball 1301 to rotate, which in turn drives the nozzle 1302 to rotate to its maximum angle, allowing the nozzle 1302 to be retracted into the body 110, protecting the nozzle 1302 from damage and improving the service life of the device.

[0053] The cleaning assembly 140 includes a second atomizing plate 1401 and a second rotating shaft 1402. The second atomizing plate 1401 is movably disposed in the transfer chamber 1202. One end of the second rotating shaft 1402 is movably disposed on one side of the body 110, and the other end of the second rotating shaft 1402 is connected to the second atomizing plate 1401.

[0054] During operation, after spray disinfection and sterilization, the drive structure 1701 is activated, driving the second rotating shaft 1402 to rotate 90°, so that the second atomizing plate 1401 rotates to align the spray output part with the transfer chamber.

[0055] 1202, then the remaining disinfectant in the spray chamber 1203 impacts the second atomizing plate 1401, and the spray generated by the second atomizing plate 1401 impacts the wall of the transfer chamber 1202, enabling the spray to clean the transfer chamber 1202; the drive structure 1701 can also rotate the first atomizing plate 1205 through the third rotating shaft 1702. When the first atomizing plate 1205 rotates 180°, the output end of the first atomizing plate 1205 can be turned in the opposite direction to the original direction, towards the spray chamber 1203. The spray generated by the first atomizing plate 1205 impacts the wall of the spray chamber 1203, enabling the spray to clean the spray chamber 1203, reducing the cleaning difficulty and improving the quality of subsequent spray disinfection and sterilization;

[0056] Furthermore, the first atomizing plate 1205 and the second atomizing plate 1401 can be linked together through the driving structure. The first atomizing plate 1205 and the second atomizing plate 1401 have different specifications. The bubbles produced by the second atomizing plate 1401 are larger. After the second atomizing plate 1401 cleans, the first atomizing plate 1205 cleans again. This allows for tiered cleaning, reducing the difficulty of cleaning and improving the cleaning effect.

[0057] The drive assembly 170 includes a drive structure 1701, a third rotating shaft 1702, a first pulley system 1703, a second pulley system 1704, and a third pulley system 1705. The drive structure 1701 is located on the top of the body 110. One end of the third rotating shaft 1702 is movably located on one side of the body 110, and the other end of the third rotating shaft 1702 is connected to the first atomizing plate 1205. One end of the second rotating shaft 1402 is connected to the output end of the drive structure 1701. The second rotating shaft 1402 and the third rotating shaft 1702 are driven by the first pulley system 1703, and the third rotating shaft 1702 and the first rotating shaft 1303 are driven by the second pulley system 1704.

[0058] The drive structure 1701 includes a drive motor and a reducer. The drive motor is connected to the reducer, and the reducer is connected to the second rotating shaft 1402. The first pulley system 1703, the second pulley system 1704, and the third pulley system 1705 each include two pulleys and a transmission belt.

[0059] During operation, the drive structure 1701 drives the various components to switch and coordinate at different working stages through the pulley system, thereby improving the synchronization of the device.

[0060] The fresh air drying assembly 150 includes a ventilation plate 1501, a fan 1502, a heater 1503, and an air duct 1504. A ventilation slot 1505 is provided on one side of the body 110. The ventilation plate 1501 is connected to the movable shaft 1208. The fan 1502 is located on one side of the ventilation plate 1501. The ventilation plate 1501 and the fan 1502 are located inside the ventilation slot 1505. The heater 1503 is located on one side of the ventilation slot 1505. One end of the air duct 1504 is connected to the ventilation slot 1505, and the other end of the air duct 1504 is connected to the transfer chamber 1202. The heater 1503 is located on one side of the fan 1502.

[0061] During operation, in the disinfection and sterilization process, the fan 1502 is started, and fresh air is introduced into the ventilation slot 1505 through the fresh air duct 220. Then, the fresh air is output to the cabin through the fan 1502, which can improve the air quality in the cabin.

[0062] Moreover, when cleaning the interior of the machine 110, after spraying disinfection and sterilization, the internal humidity is relatively high. At this time, the heater 1503 is activated, and the fan 1502 is used to input fresh air and output hot air to regulate the humidity in the cabin and improve the environmental quality inside the cabin.

[0063] After cleaning, the drive structure 1701 drives the second rotating shaft 1402 to rotate, thereby driving the first atomizing plate 1205 and the movable shaft 1208 connected to it to rotate. Since the ventilation plate 1501 is connected to the movable shaft 1208, the ventilation plate 1501 drives the fan 1502 to rotate, so that the output end of the fan 1502 is aligned with the inside of the ventilation slot 1505. In conjunction with the heater 1503, the gas is input into the air supply pipe 1504, and the air supply pipe 1504 inputs the gas into the transfer chamber 1202 to dry the transfer chamber 1202, which improves the cleaning effect. Moreover, the fan 1502 can play different roles in different working stages.

[0064] The inlets of heater 1503 and air duct 1504 are located on one side of ventilation plate 1501.

[0065] The anti-backflow assembly 160 includes a fourth rotating shaft 1601, an adjusting shaft 1602, a fixed block 1603, and a blocking block 1604. One end of the fourth rotating shaft 1601 is movably disposed on one side of the body 110. The adjusting shaft 1602 is movably disposed on one side of the water supply pipe 1206 and located inside the water supply pipe 1206. The other end of the fourth rotating shaft 1601 is connected to one end of the adjusting shaft 1602. The fixed block 1603 is fixedly disposed on the inner wall of the water supply pipe 1206. The blocking block 1604 is connected to the adjusting shaft 1602 and is located above the fixed block 1603. Both the fixed block 1603 and the blocking block 1604 are semi-cylindrical structures. The fourth rotating shaft 1601 is driven by the second rotating shaft 1402 through a third pulley system 1705.

[0066] The fixing block 1603 and the blocking block 1604 each occupy half of the space of the water pipe 1206.

[0067] The feature is that a sewage pipe 210 is provided inside the body 110, and one end of the sewage pipe 210 is connected to the transfer chamber 1202.

[0068] The unit 110 is equipped with a fresh air duct 220, one end of which is connected to the ventilation slot 1505;

[0069] The working steps of the spray disinfection and sterilization device for the air in the detection chamber of a medical infrared thermal imager according to the present invention are as follows:

[0070] Spray disinfection:

[0071] Disinfectant is stored in the water storage chamber 1201. Driven by the water pump 1207, the disinfectant is input from the water storage chamber 1201 into the transfer chamber 1202, and then from the transfer chamber 1202 into the spray chamber 1203. In the spray chamber 1203, the disinfectant hits the first atomizing plate 1205 and is atomized. Then it enters the mounting head 1204 and is sprayed out through the nozzle 1302.

[0072] Input fresh air:

[0073] Start the fan 1502, and fresh air is introduced into the ventilation slot 1505 through the fresh air duct 220, and then the fresh air is output into the cabin through the fan 1502;

[0074] Spray adjustment:

[0075] The drive structure 1701 is activated, which drives the second rotating shaft 1402 to rotate by no more than 60°, and can rotate clockwise or counterclockwise. The second rotating shaft 1402 drives the third rotating shaft 1702 to rotate through the first pulley system 1703. The third rotating shaft 1702 drives the first rotating shaft 1303 to rotate through the second pulley system 1704. The first rotating shaft 1303 causes the movable ball 1301 to rotate, indirectly adjusting the angle of the nozzle 1302.

[0076] Clean the inside:

[0077] After spray disinfection and sterilization, the drive structure 1701 is activated, which drives the second rotating shaft 1402 to rotate 90°, so that the second atomizing plate 1401 rotates to align the spray output part with the transfer chamber 1202. Then, the remaining disinfectant water in the spray chamber 1203 impacts the second atomizing plate 1401, and the spray generated by the second atomizing plate 1401 impacts the wall of the transfer chamber 1202, so that the spray can clean the transfer chamber 1202.

[0078] Furthermore, the drive structure 1701 can also rotate the first atomizing plate 1205 via the third rotating shaft 1702. When the first atomizing plate 1205 rotates 180°, the output end of the first atomizing plate 1205 can be directed in the opposite direction to the original direction, towards the spray chamber 1203. The spray generated by the first atomizing plate 1205 impacts the wall of the spray chamber 1203, enabling the spray to clean the spray chamber 1203.

[0079] At this time, the first rotating shaft 1303 causes the movable ball 1301 to rotate, which drives the nozzle 1302 to rotate to the maximum angle, so that the nozzle 1302 can be retracted into the body 110 and protected from damage.

[0080] drying:

[0081] After spray disinfection and sterilization, the internal humidity is relatively high. At this time, the heater 1503 is activated, and the fan 1502 is used to input fresh air and output hot air to regulate the humidity in the cabin.

[0082] After cleaning, the drive structure 1701 drives the second rotating shaft 1402 to rotate, thereby driving the first atomizing plate 1205 and the movable shaft 1208 connected to it to rotate. Since the ventilation plate 1501 is connected to the movable shaft 1208, the ventilation plate 1501 drives the fan 1502 to rotate, so that the output end of the fan 1502 is aligned with the inside of the ventilation slot 1505. In conjunction with the heater 1503, the gas is input into the air supply pipe 1504, and the air supply pipe 1504 inputs the gas into the transfer chamber 1202 to dry the transfer chamber 1202.

[0083] Anti-backflow:

[0084] During the cleaning process, the drive structure 1701 also indirectly drives the fourth rotating shaft 1601 to rotate, thereby driving the blocking block 1604 to rotate through the adjusting shaft 1602, so that the blocking block 1604 and the fixing block 1603 cooperate to seal the water supply pipe 1206 and prevent water vapor from flowing back into the water storage chamber 1201.

Clearly, many modifications and variations can be made based on the content of this specification.
