Description

Technical Field

[0001] This invention relates to the field of ultraviolet disinfection equipment technology, specifically to a disinfection device and method for processing environmentally friendly antibacterial bottles. Background Technology

[0002] The base material of environmentally friendly antibacterial bottles is mostly made of low-carbon and environmentally friendly materials such as recycled PET, PLA biodegradable polyester, plant fiber composite environmentally friendly plastics, and high borosilicate recycled glass. The antibacterial layer of the inner wall is made of environmentally friendly antibacterial components such as inorganic nano zinc oxide, photocatalytic titanium dioxide, and plant-based antibacterial coatings, which are non-migrating and residue-free. This not only achieves carbon reduction and recycling of packaging materials, but also inhibits the growth of microorganisms through its own antibacterial properties. It is the mainstream development direction in the field of environmentally friendly packaging and hygiene protection.

[0003] Antibacterial bottles are widely used in food packaging, daily chemical containers, medical consumables, and environmentally friendly beverage packaging. Their inner walls are often coated with antibacterial coatings or modified antibacterial materials. Both the inside and outside of the bottle must be sterilized before and after use to avoid secondary contamination caused by microbial residues, while ensuring that the antibacterial layer on the inner wall is not damaged or becomes ineffective. Ultraviolet disinfection has become the mainstream disinfection method for antibacterial bottles due to its advantages of no chemical residues, fast disinfection speed, environmental friendliness, and suitability for streamlined operations. Related ultraviolet disinfection devices are also widely used in the production, cleaning, and reuse of various antibacterial bottles.

[0004] In existing technologies, some antibacterial bottles are typically sterilized using external irradiation. These devices usually have a ring-shaped ultraviolet light source inside the sterilization chamber, which directly irradiates the outer wall of the bottle to achieve sterilization. While this structure is simple to assemble, its ultraviolet irradiation mode has certain limitations. For antibacterial bottles with narrow openings, elongated shapes, or conical structures, ultraviolet light cannot effectively penetrate the deep cavity of the bottle through the narrow opening, resulting in ultraviolet irradiation blind spots easily forming in hidden critical areas such as the bottom and inner shoulder of the bottle. This method cannot achieve uniform disinfection of the entire inner wall of the bottle, making it difficult to effectively guarantee the integrity of the disinfection operation. At the same time, some devices use ultraviolet light sources arranged in a single direction for irradiation, resulting in poor overall uniformity of light distribution. This can easily lead to irradiation intensity overload in local areas of the bottle. Long-term use of this method for disinfection may cause photo-oxidative degradation of the antibacterial layer on the inner wall of the antibacterial bottle, rendering it ineffective. This damages the inherent antibacterial function of the antibacterial bottle, not only failing to guarantee the implementation of the disinfection operation but also affecting the subsequent normal use of the antibacterial bottle.

[0011] Preferably, the clamping assembly includes multiple sets of connecting rods, and multiple sets of clamping blocks are slidably connected to the outer walls of the multiple sets of connecting rods via springs. Both ends of the multiple sets of connecting rods are connected to transmission rods. A threaded rod is connected to the surface of one set of transmission rods away from the connecting rods, and a sliding rod is connected to the surface of another set of transmission rods away from the connecting rods.

[0012] Preferably, a first drive motor is connected to the top of the rotating rod, a second drive motor is connected to the bottom of the rotating seat, an air pump is installed on the upper surface of the lifting plate, the output pipe of the lifting plate extends through the central cavity of the gear to the inner wall of the first light guide rod, and a control module is installed on the inner wall of the box, and the control module transmits signals through a signal transmitter.

[0013] A sterilization method for processing environmentally friendly antibacterial bottles includes the following steps:

[0014] S1: Bottle clamping and positioning: The clamping blocks, in conjunction with the elastic elements, clamp the outer wall of the sterilization bottle and position it to facilitate subsequent sterilization operations;

[0015] S2: Initial air blowing: The first drive motor drives the rotating rod to rotate, and under the constraint of the limit rod, it drives the lifting plate to move down, so that the first light guide rod and the second light guide rod extend into the internal cavity of the antibacterial bottle. The control module starts the air pump and the second drive motor. The gas enters the internal cavity of the second light guide rod connected by the connecting hose through the cavity of the first light guide rod, and then is discharged through the air outlet pipe. During the downward movement of the second light guide rod, water droplets on the inner wall of the antibacterial bottle are peeled off. The water droplets flow orderly from bottom to top along the inner wall of the antibacterial bottle. The water droplets are discharged through the directional airflow delivery path to avoid water droplets interfering with the ultraviolet light path.

[0016] S3: Cyclone Drying: The second drive motor drives the rotating seat to rotate, causing the first and second light guide rods and the antibacterial bottle to revolve around the axis of the rotating rod. The gear and gear ring mesh to realize the rotation of the first and second light guide rods, so that the exhaust airflow forms a swirling field, eliminating the blind spot of blowing and reducing water droplet retention.

[0017] S4: Adaptive adjustment: The second light guide rod is driven by a micro motor to deflect and adjust its tilt angle so that the second light guide rod can be adapted to the taper of the inner wall of the conical or other irregularly shaped antibacterial bottle, which is convenient for sterilizing antibacterial bottles of different shapes.

[0018] S5: Ultraviolet disinfection: After the first and second light guide rods are in place, the air pump stops, and the ultraviolet lamp strips in the box and the ultraviolet lamp rods on the inner wall of the first light guide rod are turned on to disinfect the outer and inner walls of the antibacterial bottles with ultraviolet radiation.

[0019] S6: Uniform light transmission: The ultraviolet light inside the first light guide rod is shaped into parallel axial light by the reflector and collimating lens, and then transmitted to the second light guide rod through the condenser lens. It is then directionally transmitted through the gradually changing angle of the reflective groove. With the rotation of the first and second light guide rods, uniform disinfection of the antibacterial bottle is achieved, preventing photo-oxidative degradation of the antibacterial layer.

[0020] In summary, the present invention has the following main beneficial effects:

[0021] 1. This invention uses an ultraviolet lamp post to irradiate the internal cavity of a first light guide rod. Inside the first light guide rod, the ultraviolet light source, through the combined action of a reflector and a collimating lens, is shaped into parallel axial light propagating along the center of the first light guide rod's internal cavity. With the help of a condenser lens, the ultraviolet light source is transmitted to the inside of a second light guide rod. Through reflective grooves whose inclination angles linearly increase from top to bottom on the inner walls of both the first and second light guide rods, the axially transmitted ultraviolet light is radially transmitted to the inner wall of the antibacterial bottle, thus achieving uniform ultraviolet irradiation and effectively avoiding the problem of excessive local irradiation caused by uneven light distribution, ensuring disinfection efficiency. While ensuring the effectiveness of the disinfection process, it also prevents the antibacterial layer on the inner wall of the antibacterial bottle from photo-oxidative degradation due to excessive ultraviolet radiation, thus preserving the antibacterial function of the bottle to the greatest extent and extending its service life. At the same time, the ultraviolet lamp strips installed on the inner wall of the box achieve disinfection of the outer wall of the antibacterial bottle, and the ultraviolet light is transmitted through the first and second light guide rods to achieve deep cavity disinfection of the inner wall of the bottle, thereby facilitating the disinfection of the entire bottle without dead angles. Meanwhile, the interaction between the gears and the gear ring drives the first and second light guide rods to rotate, further improving the uniformity of ultraviolet irradiation, so that all directions of the inner wall of the bottle can be subjected to stable and gentle ultraviolet light, thereby improving the disinfection effect.

[0022] 2. In this invention, the first and second light guide rods are moved downwards and inserted into the bottle body by the transmission component, simultaneously completing the blowing and drying operation of the inner wall of the bottle. The airflow enters the cavity inside the first light guide rod and is then transmitted to the second light guide rod through the connecting hose. The airflow inside the second light guide rod is discharged from the air outlet pipe. The discharged airflow can follow the movement of the second light guide rod and directly act on the deep cavity area inside the bottle. This can effectively remove water droplets adhering to the inner wall of the antibacterial bottle after cleaning, avoid the water droplets from refracting and scattering ultraviolet rays, and eliminate the adverse effects of residual moisture on the ultraviolet disinfection effect. During the blowing and drying operation, the first light guide rod revolves around the axis of the rotating rod while rotating on its own axis, which can drive the airflow to form a circumferential swirling air field. The swirling airflow can closely follow the curved surface of the inner wall of the bottle, avoiding the blind spots of airflow blowing that exist in the static air outlet to a certain extent, greatly improving the drying uniformity of the inner wall, and thus providing conditions for subsequent ultraviolet disinfection.

[0023] 3. By driving the second light guide rod with a micro motor to adaptively deflect, the tilt angle of the second light guide rod can be matched with the taper of the inner wall of the conical or other irregularly shaped antibacterial bottle. This significantly improves the device's adaptability to different shapes of antibacterial bottles and enhances the overall adaptability and flexibility of the disinfection device.

[0035] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0036] An environmentally friendly sterilization device for processing antibacterial bottles, such as Figure 1 - Figure 10As shown, the device includes a housing 1. A rotating seat 2 is rotatably connected to the bottom of the inner wall of the housing 1. A second drive motor is connected to the bottom of the rotating seat 2. The second drive motor is installed at the bottom of the inner wall of the housing 1. When the second drive motor drives the rotating seat 2 to rotate, it can uniformly disinfect the outer wall of the sterilization bottle. The upper surface of the rotating seat 2 is provided with a clamping assembly for holding the sterilization bottle. Above the clamping assembly is a light-guiding sterilization assembly. Above the light-guiding sterilization assembly is a transmission assembly for driving its movement. The transmission assembly includes a rotating rod 41 rotatably connected to the center position of the inner wall of the rotating seat 2. A first drive motor is connected to the top of the rotating rod 41. The first drive motor is installed at the bottom of the inner wall of the housing 1. On the mounting plate at the top of the inner wall of the box 1, the mounting plate is connected to the box 1 via a damping bearing. The rotating rod 41 can be driven to rotate by the first drive motor. The light guide disinfection assembly includes a first light guide rod 51 and a second light guide rod 52 that refract the ultraviolet light source. The first light guide rod 51 and the second light guide rod 52 can diffuse the ultraviolet light source, thereby preventing the ultraviolet light source from being too strong and affecting the antibacterial layer on the inner wall of the antibacterial bottle. The inner wall of the box 1 is equipped with ultraviolet lamp strips for disinfecting the outer wall of the antibacterial bottle. The top of the inner wall of the first light guide rod 51 is symmetrically equipped with ultraviolet lamp rods 55 for disinfecting the inner wall of the antibacterial bottle.

[0037] See Figure 2 , Figure 5 , Figure 6 It is known that the outer wall of the rotating rod 41 is machined with bidirectional threads, and the outer wall of the rotating rod 41 is threadedly connected to the lifting plate 42. Limiting rods 43 are provided on both sides of the rotating rod 41. The lifting plate 42 is slidably connected to the outer wall of the limiting rod 43. The lifting plate 42 is radially limited by the limiting rod 43. When the rotating rod 41 rotates, the lifting plate 42 can be driven to rise and fall on the outer wall of the rotating rod 41 under the action of the threads. Through the lifting plate 42, the first light guide rod 51 and the second light guide rod 52 can be driven to rise and fall synchronously, extending into the antibacterial bottle to disinfect the inside of the antibacterial bottle with ultraviolet light. The top of the limiting rod 43 is fixedly connected to the rotating plate 411. The rotating plate 411 is rotatably connected to the top of the inner wall of the box 1. The setting of the rotating plate 411 makes it easy to fix the position of the limiting rod 43, while not affecting the synchronous rotation of the rotating seat 2, the clamping component, the transmission component, and the light guide disinfection component. The rotating plate 411 is connected to the box 1 through a damping bearing.

[0038] See Figure 5 - Figure 9It is known that a gear 45 is rotatably connected below the lifting plate 42, and a gear ring 44 located below the lifting plate 42 is fixedly connected to the inner wall of the box 1. The gear ring 44 meshes with the gear 45. Since the gear ring 44 is fixedly connected to the inner wall of the box 1, when the rotating seat 2 drives the transmission component and the light-guiding disinfection component to rotate, the gear ring 44 and the gear 45 can drive the first light guide rod 51 and the second light guide rod 52 to rotate around the axis of the rotating rod 41 while rotating themselves. This facilitates uniform ultraviolet irradiation and prevents excessive local irradiation, which would affect the antibacterial layer on the inner wall of the antibacterial bottle. When the first light guide rod 51 and the second light guide rod 52 move to the set lowest point, the gear 45 just meshes with the gear ring 44, and the gear 45 is connected to the lifting plate 42 through a damping bearing.

[0039] See Figure 8 - Figure 10 It can be seen that a reflector block 53 is connected to the inner wall of the first light guide rod 51 below the ultraviolet lamp rod 55. A collimating lens 54 is provided between the ultraviolet lamp rod 55 and the reflector block 53. The top end of the second light guide rod 52 is connected to the first light guide rod 51 through a rotating shaft. A condenser lens 57 is provided between the two sets of connecting hoses 56. The ultraviolet light source generated by the ultraviolet lamp rod 55 is reflected by the reflector block 53. The ultraviolet light source is reflected by the reflector block 53 to the collimating lens 54. The collimating lens 54 shapes the ultraviolet light source along the first light guide rod 51. The parallel axial light transmitted downward from the center of the inner cavity of the light rod 51 is then transmitted to the inner wall of the second light guide rod 52 through the condenser lens 57. The inner walls of the first light guide rod 51 and the second light guide rod 52 are provided with multiple sets of reflective grooves 58 at equal intervals. The inclination angle of the reflective grooves 58 increases linearly from top to bottom. Through the setting of the reflective grooves 58, the ultraviolet light source is reflected in a directional manner and transmitted radially outward through the first light guide rod 51 and the second light guide rod 52 and directed towards the inner wall of the antibacterial bottle to disinfect the inner wall of the antibacterial bottle with ultraviolet light.

[0040] A control module is installed on the inner wall of housing 1. The control module transmits signals through a signal transmitter. The signals are manually input by the external human-machine operation control panel and transmitted to the control module on the inner wall of housing 1. Then, the signal transmitter forwards the signals to each actuator. A connecting hose 56 is symmetrically connected to the top of the second light guide rod 52. The top of the connecting hose 56 is connected to the first light guide rod 51. Air outlet pipes 521 are provided at the lower part and bottom of the outer wall of the second light guide rod 52. An air pump is installed on the upper surface of the lifting plate 42. A pneumatic rotary joint and an electric slip ring are integrated at the top of the lifting plate 42. The external fixed air pipe is connected through the fixed end of the pneumatic rotary joint, and the electrical cable is connected through the fixed end of the electric slip ring. The rotating ends of the pneumatic rotary joint and the electric slip ring rotate synchronously with the lifting plate 42, the first light guide rod 51, and the second light guide rod 52. This allows for uninterrupted airtight air supply and stable power supply during revolution and rotation, effectively avoiding cable rotation and entanglement. To address the issue of tearing and breakage, continuous rotation operation is an existing method and will not be elaborated upon here. The output pipe of the lifting plate 42 extends through the central cavity of the gear 45 to the inner wall of the first light guide rod 51. The control module can control the simultaneous start of the first drive motor, the second drive motor, and the air pump. When the lifting plate 42 drives the first light guide rod 51 and the second light guide rod 52 to descend, the air pump transmits airflow to the inner cavity of the first light guide rod 51, and then transmits the airflow to the inner cavity of the second light guide rod 52 through the connecting hose 56. Finally, the airflow is discharged through the air outlet pipe 521. During the movement of the first light guide rod 51 and the second light guide rod 52, the antibacterial bottle is dried simultaneously. At the same time, with the cooperation of the gear ring 44 and the gear 45, the first light guide rod 51 and the second light guide rod 52 rotate, thereby forming a circumferential swirling flow field. This avoids water droplet residue caused by the airflow blind zone generated by the static air outlet, laying the foundation for uniform ultraviolet irradiation in the future.

[0041] See Figure 2 and Figure 4 As can be seen, the clamping assembly includes multiple sets of connecting rods 32. The outer walls of the multiple sets of connecting rods 32 are slidably connected to multiple sets of clamping blocks 31 through spring members. Through the cooperation between the spring members and the clamping blocks 31, the outer wall of the antibacterial bottle can be clamped to prevent the antibacterial bottle from moving during the disinfection process and affecting the disinfection operation. The two ends of the multiple sets of connecting rods 32 are connected to transmission rods 33. One set of transmission rods 33 has a threaded rod connected to the surface away from the connecting rods 32, and the other set of transmission rods 33 has a sliding rod connected to the surface away from the connecting rods 32. A knob is connected to the top of the threaded rod. By rotating the knob, the threaded rod is driven to rotate. The sliding rod limits the transmission rod 33, which can drive the multiple sets of connecting rods 32 to move synchronously. This makes it easy to adapt to antibacterial bottles of different heights and to clamp and position the antibacterial bottles.

[0042] A sterilization method for processing environmentally friendly antibacterial bottles includes the following steps:

[0043] S1: Bottle clamping and positioning: The clamping block 31, in conjunction with the elastic element, clamps the outer wall of the sterilization bottle and positions it to facilitate subsequent sterilization operations;

[0044] S2: Initial air blowing: The first drive motor drives the rotating rod 41 to rotate, and under the constraint of the limit rod 43, it drives the lifting plate 42 to move down, so that the first light guide rod 51 and the second light guide rod 52 extend into the internal cavity of the antibacterial bottle. The control module starts the air pump and the second drive motor. The gas enters the internal cavity of the second light guide rod 52 connected by the connecting hose 56 through the cavity of the first light guide rod 51, and then is discharged through the air outlet pipe 521. During the downward movement of the second light guide rod 52, water droplets on the inner wall of the antibacterial bottle are peeled off. The water droplets flow orderly from bottom to top along the inner wall of the antibacterial bottle. The water droplets are discharged through the directional airflow delivery path to avoid water droplets interfering with the ultraviolet light path.

[0045] S3: Cyclone drying: The second drive motor drives the rotating seat 2 to rotate, so that the first light guide rod 51 and the second light guide rod 52 revolve around the axis of the rotating rod 41 with the antibacterial bottle. The gear 45 meshes with the gear ring 44 to realize the rotation of the first light guide rod 51 and the second light guide rod 52, so that the exhaust airflow forms a cyclone field, eliminates the blind spot of blowing, and reduces water droplet retention.

[0046] S4: Adaptive adjustment: The second light guide rod 52 is deflected by a micro motor to adjust its tilt angle so that the second light guide rod 52 can be adapted to the taper of the inner wall of the conical or other irregularly shaped antibacterial bottle, which is convenient for sterilizing antibacterial bottles of different shapes.

[0047] S5: Ultraviolet disinfection: After the first light guide rod 51 and the second light guide rod 52 are in place, the air pump stops, and the ultraviolet lamp strip of the box 1 and the ultraviolet lamp rod 55 on the inner wall of the first light guide rod 51 are turned on to disinfect the outer and inner walls of the antibacterial bottle by ultraviolet irradiation.

[0048] S6: Uniform light transmission: The ultraviolet light inside the first light guide rod 51 is shaped into parallel axial light by the reflector block 53 and the collimating lens 54, and then transmitted to the second light guide rod 52 through the condenser lens 57. It is then directionally transmitted through the reflective groove 58 with a gradually changing tilt angle. With the rotation of the first light guide rod 51 and the second light guide rod 52, uniform disinfection of the antibacterial bottle is achieved, preventing photo-oxidative degradation of the antibacterial layer.

[0049] The working principle of this invention is as follows: When disinfecting antibacterial bottles, the screw rod is rotated by turning the knob. Through the cooperation between the screw rod and the slide rod, the transmission rod 33 is driven to move up and down in the vertical direction to adjust the height of the clamping blocks 31, thereby adapting to the positioning requirements of antibacterial bottles of different heights. The antibacterial bottle is placed between the clamping blocks 31, and the outer wall of the antibacterial bottle is clamped by the cooperation of the elastic element and the limiting block, thereby achieving stable positioning of the antibacterial bottle and providing a positioning basis for subsequent disinfection operations.

[0050] After the antibacterial bottle is fixed in place, the first drive motor is started. The first drive motor drives the rotating rod 41 to rotate. The outer circumferential surface of the rotating rod 41 is machined with bidirectional threads. The rotating rod 41 is radially constrained by two sets of limiting rods 43, which in turn drives the lifting plate 42 to move vertically. When the lifting plate 42 moves downward, it simultaneously drives the first light guide rod 51 and the second light guide rod 52 to move downward, so that the first light guide rod 51 and the second light guide rod 52 extend into the internal cavity of the antibacterial bottle, which facilitates the subsequent disinfection operation.

[0051] During the downward movement of the first light guide rod 51 and the second light guide rod 52, the control module controls the air pump and the second drive motor to start synchronously. The air pump delivers dry gas to the internal cavity of the first light guide rod 51, and then guides the gas in the internal cavity of the first light guide rod 51 to the internal cavity of the second light guide rod 52 through the connecting hose 56. Finally, the gas is discharged outward through the air outlet pipe 521. Thus, the inner wall of the antibacterial bottle is blown and dried simultaneously during the downward movement of the first light guide rod 51 and the second light guide rod 52. After the antibacterial bottle completes the cleaning process, water droplets are easily attached to its inner wall due to its structural characteristics. The airflow discharged through the air outlet pipe 521 can fully peel off and dry the water droplets attached to the inner wall, avoiding the refraction and scattering interference of residual water droplets on the subsequent propagation path of ultraviolet rays, and ensuring the uniformity of ultraviolet disinfection operation.

[0052] During the blowing and drying process, the second drive motor drives the rotating seat 2 to rotate. Under the transmission action of the rotating seat 2, the first light guide rod 51 and the second light guide rod 52 above it, together with the antibacterial bottle, rotate synchronously around the axis of the rotating rod 41. At the same time, under the meshing transmission of the gear 45 and the gear ring 44, the first light guide rod 51 and the second light guide rod 52 rotate synchronously around the axis of the gear 45. At this time, the airflow discharged from the air outlet 521 will form a circumferential swirling flow field when the second light guide rod 52 rotates. This swirling airflow can closely fit the curved surface of the inner wall of the antibacterial bottle. Compared with the static direct airflow, it can effectively adapt to various antibacterial bottles of different shapes, reduce the problem of local water droplet retention to a certain extent, and avoid water droplet residue caused by the airflow blind zone generated by the static air outlet, laying the foundation for subsequent uniform ultraviolet irradiation.

[0053] When performing sterilization operations on antibacterial bottles with irregular structures, such as conical antibacterial bottles, the second light guide rod 52 is deflected by a micro motor, and the tilt angle of the second light guide rod 52 is adjusted so that the tilt angle of the second light guide rod 52 matches the taper of the inner wall of the conical antibacterial bottle, thus making it easier to adapt to antibacterial bottles of different shapes.

[0054] After the first light guide rod 51 and the second light guide rod 52 are moved to the set low position, the air pump stops supplying air and the ultraviolet lamp strip and ultraviolet lamp rod 55 inside the box 1 are turned on simultaneously, and the ultraviolet lamp strip is used to carry out ultraviolet irradiation disinfection of the outer wall of the antibacterial bottle.

[0055] After the ultraviolet lamp pole 55 is turned on, the ultraviolet light source generated by the ultraviolet lamp pole 55 is reflected by the reflector block 53 to the surface of the collimating lens 54. The collimating lens 54 shapes the ultraviolet light source into parallel axial light that is transmitted downward along the center of the inner cavity of the first light guide rod 51. At the same time, through the optical path coupling effect of the condenser lens 57, the ultraviolet light source inside the first light guide rod 51 is transmitted to the inner cavity of the second light guide rod 52. Since both the inner walls of the first light guide rod 51 and the second light guide rod 52 are provided with reflective grooves 58, and the inclination angle of the reflective grooves 58 increases linearly from top to bottom, the first light guide rod 51 and the second light guide rod 52 can be made more transparent. The axial ultraviolet light source inside the cavity is directionally reflected by the reflective grooves 58 at different angles, and transmitted radially outward through the first light guide rod 51 and the second light guide rod 52, and directed towards the inner wall of the antibacterial bottle. In conjunction with the rotational motion of the first light guide rod 51 and the second light guide rod 52, uniform disinfection of the entire inner wall is achieved, preventing uneven light distribution and localized excessive irradiation. While achieving efficient disinfection, it can effectively prevent the antibacterial layer on the inner wall of the antibacterial bottle from photo-oxidative degradation due to excessive ultraviolet irradiation, ensuring the functionality and service life of the antibacterial bottle.

8. A disinfection method for processing environmentally friendly antibacterial bottles, applicable to the disinfection device for processing environmentally friendly antibacterial bottles as described in claim 7, the method comprising the following steps: S1: Bottle clamping and positioning: The outer wall of the sterile bottle is clamped by the clamping block (31) in conjunction with the elastic element to position the sterile bottle, which facilitates subsequent disinfection operations; S2: Initial air blowing: The first drive motor drives the rotating rod (41) to rotate, and under the constraint of the limit rod (43), it drives the lifting plate (42) to move down, so that the first light guide rod (51) and the second light guide rod (52) extend into the internal cavity of the antibacterial bottle. The control module starts the air pump and the second drive motor. The gas enters the internal cavity of the second light guide rod (52) connected by the connecting hose (56) through the cavity of the first light guide rod (51), and then is discharged through the air outlet pipe (521). During the downward movement of the second light guide rod (52), the water droplets on the inner wall of the antibacterial bottle are peeled off. The water droplets flow orderly from bottom to top along the inner wall of the antibacterial bottle. The water droplets are discharged through the directional airflow delivery path to avoid the water droplets interfering with the ultraviolet light path. S3: Cyclone drying: The second drive motor drives the rotating seat (2) to rotate, so that the first light guide rod (51) and the second light guide rod (52) revolve around the axis of the rotating rod (41) with the antibacterial bottle. The gear (45) meshes with the gear ring (44) to realize the rotation of the first light guide rod (51) and the second light guide rod (52), so that the exhaust airflow forms a cyclone field, eliminates the blind spot of the blow-off, and reduces water droplet retention; S4: Adaptive adjustment: The second light guide rod (52) is deflected by a micro motor to adjust its tilt angle so that the second light guide rod (52) can be adapted to the taper of the inner wall of the conical or other irregular antibacterial bottle, which is convenient for disinfecting antibacterial bottles of different shapes; S5: Ultraviolet disinfection: After the first light guide rod (51) and the second light guide rod (52) are in place, the air pump stops, and the ultraviolet lamp strip of the box (1) and the ultraviolet lamp rod (55) on the inner wall of the first light guide rod (51) are turned on to disinfect the outer and inner walls of the antibacterial bottle with ultraviolet radiation. S6: Uniform light transmission: The ultraviolet light inside the first light guide rod (51) is shaped into parallel axial light by the reflector (53) and collimating lens (54), and then transmitted to the second light guide rod (52) through the condenser lens (57). It is then directionally transmitted through the reflective groove (58) with a gradually changing tilt angle. The rotation of the first light guide rod (51) and the second light guide rod (52) together achieves uniform disinfection of the antibacterial bottle and prevents photo-oxidative degradation of the antibacterial layer.
