TECHNICAL FIELD
[0001] The present application relates to the technical field of medical supplies, in particular to an automatic pop-up device for storing and taking iodophor cotton swabs. BACKGROUND
[0002] In medical care, home first aid, outdoor emergency and other scenarios, iodophor cotton swabs are convenient disinfection tools, and the rationality of their storage device directly affects the efficiency, safety and disinfection effect. The mainstream iodophor cotton swab storage devices on the market are mainly divided into two categories: plastic bag packaging and ordinary cotton swab box. Although both have simple structure and low cost, they have many adaptability shortcomings in actual use, and cannot meet the efficient, sanitary and sealed needs in diversified scenarios.
[0003] Plastic bag packaging is the most basic storage form of iodophor cotton swabs. The whole is a single sealed plastic bag, and the inside is packaged with iodophor cotton swabs in a fixed number (such as single or multiple combinations). The core design logic is to isolate the outside air and pollutants through the airtightness of the plastic bag to ensure that the cotton swab is in a sterile and iodophor non-volatile state before use. When using, the package needs to be opened by tearing the easy-to-tear edge of the plastic bag, and the inside cotton swab is taken out; but this structure lacks secondary sealing design, once the package is torn open, the bag opening is in a completely open state, and the remaining cotton swabs cannot return to a sealed environment and can only be exposed to air storage. The ordinary cotton swab box is usually made of plastic or paper material and has a container-like structure. The common design is open type (the top is completely open) or simple flip type (the top is provided with a flipable cover plate). Its storage principle is to provide a centralized storage space through the box body, and to neatly place multiple iodophor cotton swabs in the box. The taking way is to directly extract from the open part or to extract after flipping the cover plate. The flip type design tries to maintain the sealing of the box by the covering effect of the cover plate when closed, but there is no precise sealing structure between the cover plate and the box, and only simple buckling or gravity adhesion can be used to form an effective airtight space.
[0004] The plastic bag packaging is limited by the "one-time tearing" usage, if the inside is a multiple cotton swab combination package, it needs to be taken one by one after tearing, and the remaining cotton swabs need to be individually found for temporary storage containers, which cannot achieve "take as you go, take as you need"; if it is a single independent package, although it can avoid the exposure of the remaining cotton swabs, it needs to tear multiple packages in succession in an emergency, which is cumbersome and wastes valuable first aid time. The open or flip design of the ordinary cotton swab box easily leads to the "taking together" problem: when the target cotton swab is extracted, the adjacent cotton swabs are easily taken out of the box and need to be manually put back into the box, which not only increases the operation steps, but also may cause the cotton swab to fall and contaminate in panic; the flip type design also needs to add the action of "flipping the cover plate", which is particularly inconvenient when operating with one hand (such as fixing the patient's wound with the other hand), further reducing the taking efficiency.
[0005] After the plastic bag is torn, the remaining cotton swab is completely exposed to the air, and droplets, dust or pollutants in the environment of hospital wards, emergency rooms and other environments, or in the family and outdoor scenes, are easy to directly adhere to the cotton swab or the iodophor infiltration area, causing the cotton swab to be contaminated; if the subsequent use of these contaminated cotton swabs contacts the wound, it may cause local infection, and even cause cross infection between patients in the medical scene. During the use of the ordinary cotton swab box, the unnecessary contact between the fingers and the cotton swabs is prominent: under the open design, the fingers need to be inserted into the box when the cotton swab is taken out, and it is easy to touch the surrounding unused cotton swabs; although the flip type design can reduce the dust falling, the use logic does not change, and the fingers may still accidentally touch the cotton heads of other cotton swabs, and these contacted cotton swabs will carry the bacteria on the hands, which may bring pollutants into the wound during subsequent use, violating the aseptic operation principle, and posing a health threat to patients with low immunity (such as the elderly, children and postoperative people). SUMMARY
[0006] In view of the deficiencies of the prior art, the purpose of the present application is to provide an automatic pop-up device for storing and taking iodophor cotton swabs to solve the problems raised in the background art.

[0015] As preferred, two vertical guide grooves are arranged on the upper end of the vertical cylinder, and two guide portions are installed on the outer surface of the lower end of the column. The two guide portions are respectively inserted into the two guide grooves.

[0020] As preferred, the lower surface of the rubber column is provided with a supporting rod, the diameter of the supporting rod is smaller than the diameter of the rubber column, and the end of the communication tube away from the center tube extends into the cylinder. The supporting rod on the lower side of the rubber column can avoid the rubber column from blocking the communication tube, ensuring that the air pressure can always be smoothly transmitted to the center tube; the extension of the communication tube into the cylinder can limit the downward movement distance of the piston, ensuring that the cylinder and the center tube are always connected, and ensuring that the ejection action is reliable.

The cross-shaped slot is naturally closed in the unused state, air is prevented from entering the central tube, the volatilization of iodophor is reduced, and the shelf life of the cotton swab is prolonged; when the cotton swab rod is ejected, the cross-shaped slot is squeezed and opened, and immediately after the cotton swab rod passes, the cross-shaped slot is closed by rebounding, so that the air circulation in the central tube is minimized, the sealing and pollution prevention are ensured, the use of the cotton swab rod is not affected, and the pain point that the sealing performance of the traditional device is lost after being torn open is solved.
[0024] As preferred, the surface of the barrel is processed with an arc-shaped opening, and a transparent plate is arranged in the arc-shaped opening, and the transparent plate is in an arc-shaped structure. The design of the transparent plate in the arc-shaped opening of the barrel can realize non-contact observation, and the remaining number and storage state of the internal cotton swabs can be directly observed without opening the device.
[0025] The beneficial effects of the present application are as follows:
[0026] (1) The opposite surfaces of the two groups of support discs are processed with through-type spiral tracks, the cotton swab rods and the cotton heads are inserted between the two groups of spiral tracks, and the two cotton heads are respectively attached to the opposite surfaces of the two support discs. The structure of "single-branch independent clamping and spiral ordered arrangement" completely solves the disadvantage of "extracting one cotton swab and taking out multiple cotton swabs" of ordinary cotton swab boxes. Each cotton swab is in an independent track clamping position, and will not touch the adjacent cotton swab during use, so that it is not necessary to manually arrange the excess cotton swabs, especially in emergency scenes such as hospital emergency and outdoor first aid, the invalid operation can be reduced, and the first aid time is saved.
[0027] (2) The pressure plate on the cover is pressed, the linkage rod drives the piston to move downward in the cylinder, the air in the cylinder is pressed into the central tube through the communication pipe, and the rubber column is pushed upward; at the same time, the linkage structure drives the column rod to move downward, the clamping block is separated from the clamping groove of the cover, the spiral spring releases the elastic potential energy, the rotating arm is rotated around the ring through the linkage plate, the driving rod pushes the cotton swab rod along the spiral track, and the cotton swab rod enters the central tube through the spiral feeding opening; finally, the rubber column ejects the cotton swab rod in the central tube, and the use is completed. The whole process only needs to be pressed by one hand to realize "automatic feeding-precise ejection", without tearing the package, opening the cover or inserting into the box to extract, and the use efficiency in emergency scenes is much higher than that of the traditional device.
[0028] (3) When the spiral spring drives the rotating arm to rotate, the clamping block is automatically clamped into the next clamping groove under the action of the second compression spring, so that the rotating arm stops rotating, and it is ensured that only one cotton swab rod is pushed into the central tube each time. The design of single-time single-branch quantitative feeding avoids the blockage caused by multiple cotton swabs entering the central tube at the same time, and ensures the stability and order of the use process.
[0029] (4) The bottom cover and the top cover at both ends of the cylinder form an outer layer protection, and the spiral track of the center tube and the support disc constitute an inner layer storage, so that external dust, droplets and pollutants cannot contact the cotton swab. Compared with the design of exposing after tearing the plastic bag, the ordinary cotton swab box is open, and the simple flip cover, the device cuts off the pollution path from the source, ensures that the unused cotton swab is always in a sterile environment, and meets the sterile operation requirements of the medical scene. During the use process, the operator does not need to touch the cotton swab body, and after pressing the pressure plate, the cotton swab rod is automatically ejected from the cross joint of the blocking assembly, and only needs to pinch the exposed part of the cotton swab rod to use, which completely avoids the problem of fingers stretching into the box and touching other cotton swabs. This non-contact taking mode eliminates the risk of hand bacteria transferring to the unused cotton swab, especially for the elderly, children, postoperative patients and other low immunity groups, which can significantly reduce the probability of wound infection and ensure use safety.

The linkage rod 203 is in a "Z" shape structure, the guide hole 1032 and the through hole are arranged in a staggered manner; a supporting rod 2035 is arranged on the lower surface of the rubber column 2036, the diameter of the supporting rod 2035 is smaller than the diameter of the rubber column 2036, and one end of the communication pipe 2033 away from the central pipe 104 extends into the cylinder 2032.
[0048] The blocking assembly comprises a support sleeve 300, which is installed on the upper surface of the top cover 103 at the middle position, and is arranged concentrically with the central pipe 104. The lower inner position and the upper inner position of the support sleeve 300 are both pasted with rubber sheets 301 by glue. The rubber sheet 301 is in a circular structure, and a cross-shaped seam 302 for passing the cotton swab rod 106 is processed on the upper surface of the rubber sheet 301.
[0049] Please refer to Figures 1-10 , the automatic pop-up device for storing and taking iodophor cotton swabs comprises a cylinder 100, the surface of which is processed with an arc-shaped opening, and a transparent plate 102 is installed in the arc-shaped opening. The transparent plate 102 is in an arc-shaped structure, and the arc-shaped transparent plate 102 is accurately matched with the arc-shaped opening of the cylinder 100 to form a complete visual monitoring surface. Medical staff or users can directly observe the remaining number of cotton swab rods 106 in the spiral track 1051 through the transparent plate 102. When the cotton swab rods 106 are stored sufficiently, the densely arranged cotton swab rods 106 and cotton heads 1061 in the spiral track 1051 can be clearly seen. As the number of taking increases, the number of vacancies in the spiral track 1051 gradually increases, and the remaining amount can be quickly judged through the transparent plate 102 to meet the subsequent use demand. This non-contact observation mode changes the traditional management logic: the ordinary cotton swab box needs to be opened to check the remaining amount, and the plastic bag needs to be torn to know the internal situation. Frequent opening or tearing of the bag will damage the sealed environment, leading to the entry of external pollutants. Through the transparent plate 102, the remaining amount can be known without opening the cover, which greatly reduces the frequency of opening the device, reduces the risk of introducing pollution due to opening from the source, ensures that the unused cotton swabs are always in a closed and sterile environment, and meets the requirements of hospital emergency rooms, operating rooms and other scenes with strict sterile requirements.
[0050] The cylinder 100 has a central tube 104 arranged concentrically with the cylinder 100. A spiral feed port 1041 is opened at the middle of the outer surface of the central tube 104. The two ends of the cylinder 100 are respectively equipped with a bottom cover 101 and a top cover 103. The top cover 103 is fitted onto the central tube 104. A support sleeve 300 is installed at the middle of the upper surface of the top cover 103. The support sleeve 300 is arranged concentrically with the central tube 104. Rubber sheets 301 are glued to the lower and upper parts of the support sleeve 300. The rubber sheet 301 has a circular structure. A cross slit 302 for the cotton swab stick 106 to pass through is processed at the middle of the upper surface of the rubber sheet 301. The bottom cover 101 and the top cover 103 at both ends of the cylinder 100 form an outer layer of protection. The central tube 104 and the spiral track 1051 of the support plate 105 form an inner layer of storage, preventing external dust, droplets and contaminants from contacting the cotton swab. Compared to the exposed plastic bags, the open design of ordinary cotton swab boxes, and the simple flip-top lid, this device cuts off the contamination path at the source, ensuring that unused cotton swabs remain in a sterile environment, meeting the aseptic operation requirements of medical settings. During use, the operator does not need to touch the cotton swab handle 106. After pressing the pressure plate 200, the cotton swab handle 106 automatically emerges from the cross-shaped seam 302. Simply pinch the exposed part of the cotton swab handle 106 for use, completely avoiding the problem of accidentally touching other cotton swabs with fingers inside the box. This contactless dispensing method eliminates the risk of transferring bacteria from hands to unused cotton swabs, significantly reducing the probability of wound infection, especially for the elderly, children, postoperative patients, and other groups with lower immunity, ensuring safe use.
[0051] Two sets of support discs 105 are fitted on the central tube 104. The opposing surfaces of the two support discs 105 are machined with spiral tracks 1051 that penetrate the support discs 105. The spiral tracks 1051 are matched with the feed inlet 1041. A cotton swab rod 106 is inserted between the two spiral tracks 1051. Both ends of the cotton swab rod 106 are wrapped with cotton heads 1061. The cotton heads 1061 at both ends of the cotton swab rod 106 are in contact with the opposing sides of the two support discs 105. The two sets of support discs 105 are arranged vertically and their opposing surfaces are machined with perfectly fitting through spiral tracks 1051. The curvature and spacing of the spiral tracks 1051 are precisely designed to fit the overall size of the cotton swab rod 106. When the cotton swab stick 106 is inserted, it horizontally engages with the corresponding slots of the two sets of spiral tracks 1051. The cotton tips 1061 at both ends are tightly attached to the opposite sides of the two support plates 105, forming a stable storage state with the stick in the track and the tips against the plate surface. This structure independently confines each cotton swab stick 106 within its dedicated spiral track 1051 slot, and the spiral tracks 1051 separate adjacent cotton swab sticks, creating a physical distance between them. This completely breaks the traditional storage logic of stacking multiple cotton swabs without fixed positions, eliminating the drawback of pulling out multiple swabs when taking out one.
[0052] In the actual use scene, thanks to the design of a single independent card position, when the operator obtains the target cotton swab rod 106, the adjacent cotton swab rod 106 is always in the respective spiral track 1051 card position and will not be offset or taken out due to the extraction action. Unlike the use of ordinary cotton swab boxes, there is no need to manually arrange the fallen or misaligned cotton swabs frequently, which greatly reduces the invalid operation steps. Especially in emergency scenes such as hospitals, emergency rooms, outdoor first aid, time is urgent, and the environment is complex, this orderly storage design can save valuable time for first aid, and medical staff or rescuers do not need to be distracted by arranging cotton swabs, and can focus on wound treatment, which meets the efficient and immediate use requirements in emergency scenes, avoids secondary waste caused by falling and pollution in panic, and ensures the smoothness of the first aid process.
[0053] In addition, the orderly arrangement of the spiral track 1051 can also improve the space utilization of the device. The spiral structure can accommodate more cotton swab rods 106 in the limited space of the cylinder 100, and each cotton swab rod 106 is arranged according to a fixed track, and the storage state is neat and uniform, which facilitates the intuitive observation of the remaining quantity through the transparent plate 102, further improves the convenience of management and use, and perfectly adapts to the batch storage and efficient use requirements in multiple scenes such as medical treatment, family, and outdoor.
[0054] The center tube 104 has a volute spring 400 sleeved on one end close to the top cover 103. The inner end of the volute spring 400 keeps the relative position unchanged with the center tube 104. The volute spring 400 is provided with a sleeve ring 404 on the lower side, which is sleeved on the center tube 104 and connected with the center tube 104. The upper side and the lower side of the sleeve ring 404 are provided with limiting rings 4041, which are in sliding contact with the sleeve ring 404. The limiting rings 4041 are sleeved on the center tube 104 and connected and fixed with the center tube 104. The two limiting rings 4041 cooperate with each other to limit the relative position of the center tube 104 and the sleeve ring 404 without affecting the rotation of the sleeve ring 404 around the center tube 104.
[0055] The outer surface of the sleeve ring 404 is provided with a rotating arm 403, and the end of the rotating arm 403 away from the sleeve ring 404 is provided with a vertical cylinder 402. The vertical cylinder 402 is provided with a second compression spring 4024 arranged vertically at the lower position in the vertical cylinder 402. The upper side of the second compression spring 4024 is provided with a column rod 4021, and the lower end of the column rod 4021 is inserted into the vertical cylinder 402. The upper end of the vertical cylinder 402 is provided with two guide grooves 4023 arranged vertically. The outer surface of the lower end of the column rod 4021 is provided with two guide portions 40213, and the two guide portions 40213 are respectively inserted into the two guide grooves 4023. The upper end of the column rod 4021 is provided with a clamping block 4022. The lower surface of the top cover 103 is annularly and equidistantly provided with a plurality of clamping grooves 1031 matched with the clamping block 4022. The clamping block 4022 is inserted into the clamping groove 1031. When the spiral spring 400 releases the elastic potential energy, it drives the rotating arm 403 to rotate around the sleeve ring 404. At this time, the second compression spring 4024 in the vertical cylinder 402 always exerts an upward elastic force on the column rod 4021, pushing the clamping block 4022 at the top end of the column rod 4021 to tightly adhere to the lower surface of the top cover 103. With the rotation of the rotating arm 403, the clamping block 4022 is separated from the current clamping groove 1031 and slides on the lower surface of the top cover 103. When the rotating arm 403 drives the push rod 4035 to push a cotton swab rod 106 to move along the spiral track 1051 to the feeding port 1041 and make it completely enter the central pipe 104, the clamping block 4022 just slides to the upper side of the next clamping groove 1031. The second compression spring 4024 instantaneously pushes the clamping block 4022 to embed into the clamping groove 1031, forming rigid limiting and forcing the rotating arm 403 to stop rotating, and the release of the elastic potential energy of the spiral spring 400 is terminated.
[0056] The spring driving-clamping limiting linkage design accurately limits the rotation range of the spiral spring 400 within the range of pushing a single cotton swab rod 106, ensuring that only one cotton swab rod 106 can enter the central pipe 104 in each driving process, realizing single-branch quantitative feeding. Compared with the traditional device without quantitative control and prone to simultaneous transportation of multiple cotton swab rods 106, the design eliminates the risk of congestion of multiple cotton swab rods 106 in the central pipe 104 or the feeding port 1041 from the structure, avoiding the interruption of use caused by congestion, without the need to disassemble and clean the pipeline, and ensuring that single cotton swab rod 106 can be accurately obtained every time, making the whole use process stable and orderly. It is especially suitable for scenes such as hospital emergency and outdoor first aid which require high continuity of the process, ensuring that the first aid operation will not be delayed due to failure in critical moments.
[0057] The outer end of the volute spring 400 is provided with a linkage plate 401, and the end away from the volute spring 400 is slidably connected with a rotating arm 403, wherein the linkage plate 401 is a "Z" shaped structure, the end away from the volute spring 400 of the linkage plate 401 is provided with a threaded head 4011, one side of the rotating arm 403 is provided with a long circular opening 4033 arranged along the length direction of the rotating arm 403, the threaded head 4011 is inserted in the long circular opening 4033 close to the collar 404 in the initial state, the end away from the linkage plate 401 of the threaded head 4011 is threadedly connected with a nut 4012, and there is a gap between the nut 4012 and the rotating arm 403, the lower side of the rotating arm 403 is provided with a rectangular rod 4034, both ends of the rectangular rod 4034 are respectively connected and fixed with both ends of the rotating arm 403, the lower side of the rotating arm 403 is provided with a vertical plate 4031, the upper end of the vertical plate 4031 is provided with a rectangular hole, the rectangular rod 4034 is inserted in the rectangular hole, the lower end of the vertical plate 4031 is provided with a poking rod 4035 for forcing the cotton swab rod 106 to move along the spiral track 1051, both ends of the poking rod 4035 respectively extend into two spiral tracks 1051, a sleeve 4032 is mounted on the middle position of the side of the poking rod 4035 away from the vertical plate 4031, the sleeve 4032 is a "C" shaped structure in cross section, the opening end of the sleeve 4032 faces the side away from the poking rod 4035, and the sleeve 4032 is clamped on one cotton swab rod 106 inside and outside the spiral track 1051. The "C" shaped sleeve 4032 on the side of the poking rod 4035 away from the vertical plate 4031 can be tightly clamped on one cotton swab rod 106 outside the spiral track 1051, and this clamping type connection can fix the relative position of the poking rod 4035 and the target cotton swab rod 106, so that the relative sliding between the poking rod 4035 and the cotton swab rod 106 is avoided when the poking rod 4035 moves. When the poking rod 4035 moves along the spiral track 1051, the cotton swab rod 106 fixed by the sleeve 4032 will generate uniform extrusion force on the adjacent cotton swab rod 106 under the pushing force: since each cotton swab rod 106 is in the independent clamping position of the spiral track 1051, the extrusion force will be transmitted along the direction of the spiral track 1051, and the subsequent cotton swab rod 106 is pushed to move one by one to the direction of the feeding port 1041, forming an orderly conveying state of pushing one in front and following one. This design avoids the problem of mispositioning of the cotton swab rod 106 caused by the force deviation of the traditional pushing structure: the precise clamping of the sleeve 4032 allows the pushing force of the poking rod 4035 to completely act on the target cotton swab rod 106, and the adjacent cotton swab rod 106 only moves along the fixed track under the constraint of the spiral track 1051, and does not appear to deviate laterally or deviate from the spiral track 1051, finally ensuring that each cotton swab rod 106 can move accurately and stably to the feeding port 1041, and prepares for the subsequent entry into the center tube 104, and adapts to the continuous and orderly conveying demand of the batch cotton swab rod 106.
[0058] The linkage plate 401 and the rotating arm 403 are flexibly and slidably connected through the threaded head 4011, the long circular opening 4033 and the nut 4012. The threaded head 4011 at one end of the linkage plate 401 penetrates into the long circular opening 4033 of the rotating arm 403, and the nut 4012 is threadedly matched with the threaded head 4011 and keeps a gap with the rotating arm 403, which not only limits the linkage plate 401 from being separated from the rotating arm 403, but also does not affect the sliding of the threaded head 4011 along the long circular opening 4033. When the spiral spring 400 gradually expands, the outer end thereof will move away from the central pipe 104 during the expansion process, and drive the linkage plate 401 to synchronously increase the distance from the central pipe 104. At this time, the threaded head 4011 will slide along the long circular opening 4033 in the direction away from the central pipe 104, providing sufficient space for the displacement of the linkage plate 401, so that the expansion action of the spiral spring 400 and the rotation action of the rotating arm 403 do not interfere with each other. This sliding matching structure solves the problem of easy jamming in rigid connection. If the linkage plate 401 and the rotating arm 403 are fixedly connected, the radial displacement of the spiral spring 400 during expansion will forcibly drive the rotating arm 403 to deviate, resulting in mutual pulling and movement of the components. By the sliding of the threaded head 4011 in the long circular opening 4033, the displacement difference generated by the expansion of the spiral spring 400 is automatically compensated, so that the spiral spring 400 can smoothly release the elastic potential energy, and the rotating arm 403 can stably rotate around the sleeve ring 404, finally realizing the cooperative movement of each component, ensuring the smooth driving process, no jamming, improving the reliability and service life of the device operation.
[0059] The top cover 103 is provided with a pressure plate 200 on the upper side, the area covered by the pressure plate 200 of the top cover 103 is provided with a guide hole 1032, a linkage rod 203 is inserted in the guide hole 1032, the upper end of the linkage rod 203 is connected and fixed with the pressure plate 200, a first compression spring 201 is arranged between the guide hole 1032 and the pressure plate 200, the first compression spring 201 is sleeved on the linkage rod 203, a piston 2034 is installed at the lower end of the linkage rod 203, a cylinder 2032 is installed on the upper surface of the bottom cover 101, a cylinder cover 2031 is installed on the upper surface of the cylinder 2032, a through hole is formed on the upper surface of the cylinder cover 2031, the piston 2034 is slidingly installed in the cylinder 2032, the lower end of the linkage rod 203 penetrates the through hole, a rubber column 2036 for lifting the cotton swab rod 106 in the center tube 104 is slidingly installed at the lower position in the center tube 104, a communication tube 2033 is installed at the lower end of the center tube 104 and communicates with the inner space of the cylinder 2032, when the cotton swab rod 106 needs to be taken, the user only needs to press the pressure plate 200 on the top cover 103 with one hand, which will trigger two core linkage mechanisms simultaneously: on the one hand, the pressure plate 200 drives the linkage rod 203 to move downward along the guide hole 1032, the piston 2034 at the lower end of the linkage rod 203 slides downward in the cylinder 2032, and the air in the cylinder 2032 is compressed; the compressed air is quickly delivered to the lower part of the center tube 104 through the communication tube 2033, forming a stable air pressure, pushing the rubber column 2036 in the center tube 104 to move upward, preparing for the subsequent cotton swab rod 106 to be ejected. On the other hand, the pressure plate 204 in the middle of the linkage rod 203 synchronously presses the ring 40211, drives the column rod 4021 to move downward along the guide groove 4023 in the vertical cylinder 402 through the ear plate 40212, the clamping block 4022 at the upper end of the column rod 4021 is separated from the clamping groove 1031 on the lower surface of the top cover 103, and the rotation restriction on the rotating arm 403 is released. At this time, the spiral spring 400 releases the stored elastic potential energy, the outer end of which drives the rotating arm 403 to stably rotate around the sleeve ring 404 through the linkage plate 401, the driving rod 4035 on the lower side of the rotating arm 403 moves along the spiral track 1051, accurately pushes the outer cotton swab rod 106, and makes it enter the center tube 104 along the spiral inlet 1041. Finally, the rubber column 2036 ejects the cotton swab rod 106 in the center tube 104, and the taking is completed. The whole process only needs to be pressed with one hand to realize "automatic feeding-accurate ejection", without tearing the package, opening the cover or stretching into the box to extract, and the taking efficiency in emergency scenes is much higher than that of traditional devices.
[0060] The outer surface of one end of the linkage rod 203 close to the top cover 103 is provided with a pressing plate 204, and the lower side of the pressing plate 204 is provided with a ring 40211 arranged concentrically in the barrel 100. The outer surface of a column 4021 is provided with an ear plate 40212 at the middle position, and the end of the ear plate 40212 away from the column 4021 is installed on the inner wall of the ring 40211. The linkage rod 203 is in a "Z" shape, and the guide hole 1032 is arranged in a staggered manner with the through hole. The linkage rod 203 is in a "Z" shape, which avoids the rotation of the pressing plate 204 around the linkage rod 203, so that the relative position of the pressing plate 204 and the barrel 100 remains unchanged. When the user presses the pressing disc 200 on the top cover 103, the linkage rod 203 moves downward synchronously, and the pressing plate 204 on the outer surface of the linkage rod 203 moves to the direction of the ring 40211 and generates a squeezing action. The ring 40211 is forced to move downward synchronously with the column 4021 connected thereto through the ear plate 40212. The lower end of the column 4021 slides along the guide groove 4023 in the vertical cylinder 402, and the second compression spring 4024 at the bottom of the vertical cylinder 402 is squeezed, so that the spring is in a compressed state; at the same time, the clamping block 4022 at the upper end of the column 4021 moves downward with the column 4021, and gradually separates from the clamping groove 1031 on the lower surface of the top cover 103, thereby releasing the rotation locking of the rotating arm 403. At this time, the constraint of the spiral spring 400 is released, and the elastic potential energy can be smoothly released to drive the rotating arm 403 to rotate and realize the pushing of the cotton swab rod 106, thereby providing power support for the taking action. When the taking is completed and the user releases the pressing disc 200, the rebounding force of the first compression spring 201 pushes the pressing disc 200 and the linkage rod 203 to reset, and the pressing plate 204 moves upward, so that the pressing plate 204 no longer applies a squeezing force to the ring 40211. At this time, the second compression spring 4024 in the vertical cylinder 402 releases the pre-stored rebounding force to push the column 4021 to reset upward along the guide groove 4023, and the clamping block 4022 at the upper end of the column 4021 moves upward synchronously, and finally accurately clamps into the corresponding clamping groove 1031 on the lower surface of the top cover 103, thereby relocking the position of the rotating arm 403.
[0061] The lower surface of the rubber column 2036 is provided with a supporting rod 2035, the diameter of the supporting rod 2035 is smaller than the diameter of the rubber column 2036, one end of the communication pipe 2033 extending into the cylinder 2032 is away from the center pipe 104, the inner diameter of the cylinder 2032 is larger than the inner diameter of the center pipe 104, the moving distance of the piston 2034 in the cylinder 2032 is one third of the moving distance of the rubber column 2036 in the center pipe 104, the guiding hole 1032 is provided with a blocking rod 202 on one side, the blocking rod 202 is in the coverage range of the pressing disc 200, and the lower end of the blocking rod 202 is connected and fixed with the top cover 103. Under the limitation of the supporting rod 2035, the rubber column 2036 is prevented from blocking the connecting position of the communication pipe 2033 and the center pipe 104, and meanwhile the one end of the communication pipe 2033 in the cylinder 2032 limits the moving distance of the piston 2034, so that the cylinder 2032 and the lower space in the center pipe 104 are always in communication. After the pressing disc 200 moves downward by a certain distance, the moving distance of the piston 2034 can magnify the moving distance of the rubber column 2036, so that the cotton swab rod 106 in the center pipe 104 can be pushed out after the pressing disc 200 moves downward by a small distance. Under the blocking of the blocking rod 202, the lowermost distance between the pressing disc 200 and the top cover 103 is limited, the protection of the first compression spring 201 is realized, and the first compression spring 201 is prevented from being damaged by excessive extrusion.
[0062] The working principle of the application is as follows:
[0063] Initial state: the cotton swab rod 106 is clamped into the clamping position of the spiral track 1051, and the two end cotton heads 1061 are respectively attached to the opposite surfaces of the supporting disc 105, so that the spiral order arrangement is formed; the outer cotton swab rod 106 is accurately fixed through the "C" type sleeve 4032 on the pushing rod 4035, so that the position is not deviated during pushing. The spiral spring 400 is in a pre-compressed energy storage state, the inner end of the spiral spring 400 is fixed with the center pipe 104, the outer end of the spiral spring 400 is slidably connected with the long circular port 4033 of the rotating arm 403 through the "Z" type linkage plate 401, the clamping mechanism at the end of the rotating arm 403 away from the sleeve ring 404 is in a locking state, the second compression spring 4024 in the vertical cylinder 402 pushes the column rod 4021 upward, so that the clamping block 4022 at the upper end of the column rod 4021 is clamped into the clamping groove 1031 on the lower surface of the top cover 103, the rotation of the rotating arm 403 is limited, and the spiral spring 400 is prevented from releasing potential energy in advance. The upper and lower two layers of rubber sheets 301 in the blocking assembly supporting sleeve 300 in the middle of the top cover 103 are naturally closed through the cross joint 302, so that the air is prevented from entering the center pipe 104; the arc-shaped transparent plate 102 on the surface of the cylinder body 100 can directly observe the remaining amount and state of the cotton swab in the spiral track 1051, so that the cotton swab rod 106 in the device is ensured to be in a sterile and iodophor non-volatile closed environment.
[0064] Use trigger: when the cotton swab needs to be taken, the user presses the pressing disc 200 on the top cover 103 with one hand, which synchronously triggers the "drive unlocking" and "ejection piece power storage" two groups of linkage mechanisms:
[0065] Ejection force storage: After the pressure plate 200 is forced, it drives the linkage rod 203 to move down along the guide hole 1032 of the top cover 103. The piston 2034 at the lower end of the linkage rod 203 synchronously slides downward in the cylinder 2032. The air in the cylinder 2032 is squeezed, and the high-pressure airflow formed is quickly delivered to the lower part of the center tube 104 through the communication pipe 2033. The high-pressure airflow acts on the rubber column 2036 in the center tube 104, pushing the rubber column 2036 to move upward along the inner wall of the center tube 104, until it is close to the feed port 1041 in the middle of the center tube 104, to prepare for subsequent receiving of the cotton swab rod 106 and ejection. At the same time, the blocking rod 202 on one side of the guide hole 1032 limits the maximum downward movement distance of the pressure plate 200, to avoid damage to the first compression spring 201 due to excessive compression.
[0066] Drive member unlocking: During the downward movement of the linkage rod 203, the pressure plate 204 on its outer surface synchronously squeezes the ring 40211, which drives the column rod 4021 to move down along the guide groove 4023 in the vertical cylinder 402 through the ear plate 40212. The column rod 4021 at the lower end squeezes the second compression spring 4024 in the vertical cylinder 402, causing the clamping block 4022 at the upper end of the column rod 4021 to be released from the clamping groove 1031 of the top cover 103, thereby releasing the rotational locking of the rotating arm 403. At this time, the energy storage constraint of the spiral spring 400 is released, and the power condition for driving the rotating arm 403 to rotate is met.
[0067] Automatic feeding: After the clamping mechanism is unlocked, the spiral spring 400 releases the pre-stored elastic potential energy, pushing the cotton swab into the center tube 104 along the spiral track 1051. The spiral spring 400 gradually expands, and its outer end pulls the rotating arm 403 to stably rotate around the sleeve ring 404 through the linkage plate 401. Since the linkage plate 401 and the rotating arm 403 are connected through the "screw head 4011-long circular port 4033" sliding connection, the distance between the linkage plate 401 and the center tube 104 increases when the spiral spring 400 expands, and the screw head 4011 slides along the long circular port 4033 away from the center tube 104, automatically compensating for the displacement difference to avoid component movement interference. When the rotating arm 403 rotates, the vertical plate 4031 on its lower side drives the push rod 4035 to move along the spiral track 1051. The clamping sleeve 4032 on the push rod 4035 firmly clamps the outer cotton swab rod 106, pushing it to move along the spiral track 1051 towards the center tube 104; at the same time, the pushed cotton swab rod 106 exerts uniform extrusion force on the adjacent cotton swab rod 106, causing the subsequent cotton swab rod 106 to follow one by one along the spiral track 1051, avoiding jamming. Finally, the outer cotton swab rod 106 passes through the spiral feed port 1041 on the outer surface of the center tube 104, accurately enters the inside of the center tube 104, and completes the automatic feeding.
[0068] Swab ejection: After the swab enters the center tube 104, the rubber column 2036 in the center tube 104 continues to move upward under the continuous pushing of high-pressure airflow and contacts the lower end of the swab rod 106; because the inner diameter of the cylinder 2032 is larger than the inner diameter of the center tube 104, the moving distance of the piston 2034 can be amplified into a larger moving distance of the rubber column 2036 through air pressure, ensuring that the rubber column 2036 can generate enough pushing force to push the swab rod 106 in the center tube 104 upward. The upper end of the swab rod 106 squeezes the cross-shaped joint 302 of the rubber sheet 301 of the blocking assembly, causing the cross-shaped joint 302 to be forced to open, and finally the swab rod 106 is ejected from the cross-shaped joint 302 to the outside of the device. The user only needs to hold the exposed swab rod 106 to use it, without touching other unused swabs throughout the process, avoiding contamination.
[0069] Reset standby: After the user uses the swab, the pressure plate 200 is released, and after the pressure plate 200 loses the downward pressure, the first compression spring 201 releases the elastic force to push the pressure plate 200 and the linkage rod 203 upward to reset, the piston 2034 moves upward with the linkage rod 203, the cylinder 2032 restores to normal pressure, and the rubber column 2036 falls to the lower part of the center tube 104, waiting for the next ejection. When the linkage rod 203 resets, the pressure plate 204 no longer squeezes the ring 40211, the second compression spring 4024 in the vertical cylinder 402 releases the elastic force to push the column rod 4021 upward to reset, and the clamping block 4022 at the upper end of the column rod 4021 reenters the next clamping groove 1031 under the top cover 103 to lock the position of the rotating arm 403, limit the continued expansion of the spiral spring 400, and ensure that only one swab can be pushed before the next use. After the swab rod 106 is taken out, the cross-shaped joint 302 of the rubber sheet 301 automatically closes under the elastic action of itself, reseals the entry of air into the center tube 104, maintains the sterile environment and iodophor concentration in the device, and completes a use cycle, waiting for the next use.
