Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a device for disinfecting, sterilizing and cleaning medical devices. Background Art

[0002] A device for disinfecting, sterilizing and cleaning medical devices is a device used for disinfecting, sterilizing and cleaning medical devices. It usually includes a disinfection chamber and a cleaning chamber, and can sterilize medical devices by means of high-temperature steam, chemical disinfectants or ultraviolet light, etc., and then clean and disinfect the medical devices through the cleaning chamber to ensure that the medical devices reach a clean and sterile state before use. This kind of device is widely used in medical institutions, laboratories and other related places, and can effectively ensure the safety and hygiene of medical devices.

[0003] For example, Chinese Patent with publication number CN118615470A discloses a special disinfection and sterilization device for medical devices, belonging to the field of disinfection and sterilization, including a housing, a disinfection and sterilization mechanism, a drying mechanism, a clamping and turning mechanism and a support plate driving mechanism. The disinfection and sterilization mechanism includes an ultraviolet lamp, a spray pipe, a sliding frame, a rotating rod, a motor 1, a water tank, a water pipe, a limiting rod and a drainage tank; the disinfectant liquid in the water tank flows into the spray pipe through the water pipe and sprays out from the spray holes of the spray pipe. The motor drives the sliding frame to move the spray pipe back and forth, so as to expand the spraying range of the spray pipe, and use the spray pipe and the ultraviolet lamp to disinfect and sterilize medical devices; the clamping and turning mechanism is symmetric left and right, including a sliding rod group, a disinfection and sterilization cabinet, a rack group, a gear group, a motor 2, a T-shaped rod, a trapezoidal plate, a rotating shaft frame, a medical device support plate, a transmission wheel, an electric cylinder 1 and a motor 3; the clamping and turning mechanism can automatically turn over medical devices, so as to disinfect and sterilize medical devices in all directions.

[0004] However, there are still some deficiencies in the above disinfection and sterilization device during actual use:

[0005] 1. First of all, the above device can disinfect and sterilize medical devices in all directions, but it can only disinfect and sterilize medical devices with a single shape each time, and cannot clamp different types of medical devices, so the device has a certain degree of singularity; moreover, it can not only disinfect and sterilize medical devices with a single shape, but also cannot disinfect and sterilize multiple medical devices each time, and can only disinfect and sterilize a single medical device, resulting in poor efficiency of disinfecting and sterilizing medical devices.

[0006] 2. In addition, the existing device has poor stability in clamping medical devices, which is likely to cause the medical devices to fall or shake during the flushing process, thus easily causing damage to some relatively precise medical devices; and the existing effect of disinfecting and sterilizing medical devices is poor, and it cannot clean the stains coagulated on the surface of the medical devices.

[0007] Therefore, under the viewpoints stated above, there is still room for improvement in the existing disinfection and sterilization devices. Summary of the Invention

Detailed implementation manners

[0045] The following is a further detailed description of the present application in conjunction with the attached Figures 1 - 15 For a further detailed description of the present application.

[0046] The embodiment of the present application discloses a device for disinfecting, sterilizing and cleaning medical instruments; mainly aiming at some medical instruments in the medical industry, such as surgical forceps, tweezers, orthopedic drills, etc.

[0047] In the prior art, although the existing device can sterilize medical devices in all directions, it can only sterilize and disinfect medical devices of a single shape each time, and cannot clamp medical devices of different types. Therefore, the device has a certain degree of singularity. Moreover, it can not only sterilize and disinfect medical devices of a single shape, but also cannot sterilize and disinfect multiple medical devices each time. It can only sterilize and disinfect a single medical device, resulting in poor efficiency of sterilizing and disinfecting medical devices.

[0048] In addition, the stability of the existing device for clamping medical devices is poor, which easily causes the medical devices to fall or shake during the flushing process, thus easily damaging some relatively precise medical devices. And the effect of sterilizing and disinfecting medical devices by the existing method is poor, and the stains coagulated on the surface of the medical devices cannot be cleaned.

[0049] Therefore, this application proposes a device for sterilizing, disinfecting and cleaning medical devices to solve the above problems.

[0050] Embodiment 1:

[0051] First of all, for some medical devices such as surgical forceps, tweezers, orthopedic drills, stethoscopes, scalpels, etc., when medical staff are performing inspection operations or surgical operations on patients, various auxiliary medical devices are often used. Some auxiliary medical devices are disposable products and cannot be reused after use. However, some auxiliary medical devices are not disposable products. After reasonable and standard sterilization, disinfection and cleaning treatment, they can be reused multiple times. And these reusable medical devices have different functions and different shapes and sizes. And a device for sterilizing, disinfecting and cleaning medical devices of this application can effectively sterilize, disinfect and clean medical devices of different sizes and types, as follows.

[0052] Refer to Figure 1 and Figure 2 As shown, a device for sterilizing, disinfecting and cleaning medical devices includes a stationary working box 1. Inside the working box 1, there are a sterilization and disinfection area 11 for sterilizing and disinfecting medical devices and a cleaning area 10 for cleaning medical devices.

[0053] First of all, the bottom of the working box 1 is provided with known rollers, which can be manually controlled to move to ensure the portability of the entire device. Especially during surgery, it can effectively realize the timely cleaning, disinfection and sterilization of used medical devices and ensure the safety of medical devices.

[0054] Refer to Figure 2 and Figure 3As shown in the figure, two sets of feeding grooves 12 corresponding to the bearing pallets 212 and used for placing instruments are provided at the upper end of the working box 1. Two sets of picking grooves 13 corresponding to the bearing pallets 212 and used for picking up instruments are also provided at the upper end of the working box 1. Cover plates 14 are provided on both the feeding grooves 12 and the picking grooves 13.

[0055] A conveying device 2 is provided in the working box 1. The conveying device 2 includes a conveying chain 20 and a number of bearing platforms 21 for bearing the instruments to be disinfected and sterilized, which are arranged at equal intervals on the conveying chain 20.

[0056] In the initial state, the bearing platform 21 is located in the feeding groove 12 of the working box 1, and the cover plate 14 covers the bearing platform 21 to prevent external impurities from polluting its interior.

[0057] When it is necessary to disinfect, sterilize and clean the instruments to be processed, first open the cover plate 14 on the feeding groove 12, then place the instruments to be processed on the bearing platform 21, and then press the power-on start button of the whole device. At this time, the whole device starts, and the cover plate 14 is covered. The conveying device 2 controls the bearing platform 21 to move in each different functional area in the working box 1, and sequentially performs cleaning, disinfection and sterilization treatments on it. After the surface of the processed instruments is dried, the conveying device 2 conveys them to the picking groove 13. Finally, open the cover plate 14 of the picking groove 13, take them out from the picking groove 13, and cover the cover plate 14.

[0058] First is the fixation of the instruments, which specifically involves the bearing platform 21. Refer to Figure 3 As shown in the figure, the bearing platform 21 includes a number of bearing frames 210 arranged at equal intervals along the movement track of the conveying chain 20. Positioning columns 211 are inserted and installed on both sides of the bearing frame 210 along the length direction. Two positioning columns 211 are rotatably installed together through bearings on the side close to each other with a bearing pallet 212. A number of hollow holes 213 are equally spaced on the bearing pallet 212, and the instruments placed on the bearing pallet 212 are flushed on both sides through the hollow holes 213.

[0059] In the initial state, the bearing pallet 212 of the bearing platform 21 is located in the feeding groove 12 of the working box 1. After opening the corresponding cover plate 14, place the instruments to be processed (such as a surgical knife handle) on the upper end surface of the bearing platform 21, and then insert the limiting unit 6 into the hollow holes 213 of the bearing platform 21. Press down the instruments through the limiting unit 6, and the instruments can be fixed on the bearing pallet 212.

[0060] The hollow holes 213 on the bearing pallet 212 can ensure that both sides of the instruments fixed on the bearing pallet 212 can be flushed subsequently.

[0061] Furthermore, the size of the carrier tray 212 is relatively large. According to the sizes of different instruments and a reasonable layout, multiple different types of instruments (such as a surgical knife handle, forceps, and an orthopedic drill) can be placed on the same carrier tray 212 at different angles, which can ensure that the entire carrier tray 212 can limit and fix multiple instruments simultaneously, enabling them to be disinfected and cleaned at the same time, greatly improving the efficiency of disinfection and cleaning of the instruments.

[0062] Therefore, the carrier platform 21 of the present application can not only limit and fix instruments of different sizes, but also limit and fix instruments of different functions and types, greatly ensuring the applicability of the entire device and improving the diversity of product cleaning, disinfection, and sterilization of the device.

[0063] After different types of instruments are installed on the upper end surface of the carrier tray 212, in order to further improve the ability of the carrier tray 212 to limit and fix more instruments for disinfection, the present application also proposes a damping block 52.

[0064] When specifically limiting and fixing the instrument to the carrier tray 212, it needs to be realized through the limiting unit 6. For specific reference, Figure 4 、 Figure 5 and Figure 6 As shown, the carrier tray 212 is also provided with a limiting unit 6 for limiting the instrument. The limiting unit 6 includes a limiting fork 60 inserted into the hollow hole 213 of the carrier tray 212, and the limiting fork 60 is in a U-shaped structure.

[0065] The limiting fork 60 is symmetrically provided with limiting holes 61, and a control rod 62 is commonly inserted into the two limiting holes 61. Linkage columns 63 are installed at both ends of the control rod 62, and a conical linkage block 64 is integrally provided at the bottom of the linkage column 63. A linkage compression spring 65 is installed between the conical linkage block 64 and the inner wall of the limiting fork 60.

[0066] During specific implementation, the instrument to be processed is placed on the carrier tray 212. Then, the limiting fork 60 is picked up, and the control rod 62 at the top of the limiting fork 60 is pressed, so that the control rod 62 approaches the limiting fork 60. At this time, the conical linkage block 64 at the bottom of the control rod 62 is separated from the limiting block 66.

[0067] The limiting compression spring 67 on the limiting block 66 pulls the limiting block 66 to move inward into the limiting fork 60 until the limiting block 66 retracts into the limiting fork 60. At this time, the outer walls at both ends of the limiting fork 60 are smooth without any protrusions. Then, the limiting fork 60 is inserted into the hollow hole 213 on the carrier tray 212, and then the control rod 62 is released.

[0068] After the control lever 62 is released, the linkage compression spring 65 on the conical linkage block 64 controls its upward movement. The conical linkage block 64 squeezes the limit block 66 to protrude outward along the movable slot of the limit fork 60 until the limit block 66 is inserted into the clamping hole 68 in the hollow hole 213 of the bearing support plate 212.

[0069] At this time, the limit fixation of the instrument can be completed. The instrument is restricted between the bearing support plate 212 and the limit fork 60. It should be noted that the installation position of the limit fork 60 can be comprehensively considered according to one's own needs and the shape of the instrument. At the same time, multiple limit forks 60 can also be installed on the instrument to improve its stability when being limited and fixed on the bearing support plate 212.

[0070] Refer to Figure 7 、 Figure 8 and Figure 9 As shown, a plurality of movable slots are provided at both ends of the limit fork 60. The limit block 66 is slidably installed in the movable slot. A limit compression spring 67 is connected between the limit block 66 and the limit fork 60. One side of the limit block 66 is in movable contact with the conical linkage block 64.

[0071] A clamping hole 68 is also provided in the hollow hole 213 of the bearing support plate 212. The limit block 66 is movably arranged in the clamping hole 68.

[0072] In the initial state, the limit block 66 protrudes outward from the movable slot of the limit fork 60. The limit compression spring 67 always has an outward pulling force on the limit block 66, and the linkage compression spring 65 always has a lifting force for lifting the control lever 62 upward.

[0073] The limit unit 6 in this application can comprehensively adjust the position of the limit unit 6 according to its own needs and the shape of the instrument. For different types of instruments, the limit fork 60 of the limit unit 6 can be installed at different positions. At the same time, the instrument can also be limited at different positions by multiple limit forks 60, which greatly ensures the stability of the instrument limit.

[0074] Refer to Figure 10 and Figure 11 As shown, this is the conveying device 2 of this application, which is used for conveying the instrument inside the working box 1. The conveying device 2 is arranged on the working box 1. The conveying device 2 includes a conveying chain 20 and a plurality of bearing platforms 21 for bearing the instruments to be disinfected and sterilized arranged at equal intervals on the conveying chain 20. The conveying chain 20 has a square structure and is arranged inside the working box 1.

[0075] A disinfection and sterilization device 3 for disinfecting and sterilizing the instrument is arranged in the disinfection and sterilization area 11 of the working box 1, and a cleaning device 4 for cleaning the sundries on the surface of the instrument is arranged in the cleaning area 10 of the working box 1.

[0076] After the instrument is fixed on the carrier pallet 212, the conveying device 2 is started, and the conveying chain 20 on the conveying device 2 rotates. The conveying chain 20 drives the carrier pallets 212 on both sides thereof to move along the movement track of the conveying chain 20, driving it to pass through the cleaning area 10 and the disinfection and sterilization area 11 in sequence, and then taking it out from the material taking slot 13 of the working box 1 after drying.

[0077] Refer to Figure 11 As shown, it should be noted that a number of conveying rollers 22 are provided at the corners of the conveying chain 20. A first bevel gear 24 is installed on one side of the conveying rollers 22. A second bevel gear 25 is engaged with the first bevel gear 24. A conveying motor 23 is installed on the second bevel gear 25. The conveying motor 23 is arranged on the working box 1. Both the first bevel gear 24 and the second bevel gear 25 are rotatably arranged on the working box 1. The conveying motor 23 can control the conveying rollers 22 to drive the conveying chain 20 to rotate counterclockwise through the cooperation between the first bevel gear 24 and the second bevel gear 25.

[0078] The functions of the first bevel gear 24 and the second bevel gear 25 are to ensure that the conveying motor 23 and the conveying chain 20 are distributed in parallel, and to prevent the instrument from colliding with the conveying motor 23 during the movement.

[0079] Furthermore, it should be noted that carrier pallets 212 are provided at all four corners of the conveying chain 20. The four groups of carrier pallets 212 can sequentially place the instruments to be processed, and then the controller moves along the inside of the working box 1. Different operations are simultaneously performed on the four groups of carrier pallets 212 during the movement, thereby forming a cycle of instrument installation, cleaning, disinfection and sterilization, and drying and material taking, thus further improving the efficiency of instrument disinfection, sterilization and cleaning.

[0080] For example, when the first group of carrier pallets 212 is performing disinfection and sterilization, the second group of carrier pallets 212 can perform flushing operations, while the third group of carrier pallets 212 can just install the instruments to be processed. After the instruments dried on the fourth group of carrier pallets 212 are taken off, they can queue up waiting for the installation of the instruments.

[0081] First, the carrier pallet 212 moves to the cleaning area 10 inside the working box 1, and the stains on the surface of the instrument are cleaned by the cleaner 4 to dissolve the stains and prevent them from remaining on the surface of the instrument, as specifically shown below:

[0082] Refer to Figure 12 、 Figure 13 and Figure 14As shown, the washer 4 includes a washing tank 40 filled with washing liquid. The washing tank 40 is slidably arranged on the inner wall of the working tank 1. An electric push rod 41 is installed on one side of the working tank 1 where the washing tank 40 is located. The output end of the electric push rod 41 is connected to the washing tank 40, and washing pipes 42 are provided at both the top and bottom of the washing tank 40.

[0083] When the carrying pallet 212 moves to the washing area 10 inside the working tank 1, the electric push rod 41 is activated. The output end of the electric push rod 41 drives the washing tank 40 to approach the carrying pallet 212 until the washing tank 40 sleeves around the periphery of the carrying pallet 212. Subsequently, a large amount of dissolving liquid is poured out from the upper part to the lower part by the washing pipe 42 at the top of the washing tank 40 onto the surface of the instrument, and a large amount of dissolving liquid is sprayed from the lower part to the upper part by the washing pipe 42 at the bottom of the washing tank 40 onto the surface of the instrument, so that the instruments fixed on both sides of the carrying pallet 212 can come into contact with the dissolving liquid. The stains on its surface are dissolved by the dissolving liquid and then washed off under the pressure of the dissolving liquid. After the dissolving liquid is sprayed, clean water can be sprayed through the washing pipe 42 to wash away the dissolving liquid and ensure the cleanliness of the instrument.

[0084] It should be noted that when instruments are installed on both sides of the carrying pallet 212, the instruments are placed in a staggered manner, which can effectively improve the contact between the instruments and the dissolving liquid.

[0085] Embodiment 2: On the basis of Embodiment 1, further to improve the efficiency of separating stains from the instrument, the present application also proposes a vibrating rod 44. Specifically, refer to Figure 13 and Figure 14 As shown, a rotating disk 43 is rotatably installed on the inner wall of the washing tank 40. The surface of the rotating disk 43 is in an uneven structural state, and a vibrating rod 44 abuts against the rotating disk 43. The vibrating rod 44 is connected to the inner wall of the washing tank 40 through a vibrating spring 45. The vibrating rods 44 are horizontally distributed, and the end of the vibrating rod 44 away from the rotating disk 43 is movably abutted against the positioning post 211 of the carrying frame 210 by vibration. A rotating motor 46 is installed on one side of the rotating disk 43.

[0086] The washer 4 in the present application can cooperate with the vibrating rod 44 to control the carrying pallet 212 and the instrument to perform high-speed swinging in the horizontal direction in the dissolving liquid. The lateral force generated by the swinging, combined with the flushing of the washer 4, can effectively improve the efficiency of stain cleaning and avoid stains being difficult to remove by adhering to the instrument.

[0087] During specific implementation, the rotary motor 46 is started, and the rotary motor 46 controls the rotation of the rotary disk 43. During the rotation of the rotary disk 43, the vibrating rod 44 is controlled to reciprocate. While the vibrating rod 44 reciprocates, it reciprocally presses the positioning posts 211 on the bearing frame 210, enabling the bearing tray 212 in the bearing frame 210 to swing horizontally reciprocally. After contacting the dissolving liquid and clean water during the swinging process, a lateral force can be exerted on the stains on the surface of the instrument, thereby improving the separation efficiency between the stains and the instrument and ensuring the stain cleaning effect.

[0088] After the instrument is cleaned in the cleaning area 10, the instrument moves to the disinfection and sterilization area 11. Specifically, refer to Figure 15 As shown, the disinfection sterilizer 3 includes a driving shaft 30 rotatably installed along the height direction on the inner wall of the working box 1. Two symmetrically distributed driving blocks 31 are screwed on the driving shaft 30. Two driving rods 32 are hinged on the two driving blocks 31. The two driving rods 32 are symmetrically distributed, and the ends of the two driving rods 32 away from the driving blocks 31 are jointly hinged and installed with a spray shower 33. A driving motor 34 is provided on the driving shaft 30, and the driving motor 34 is arranged on the working box 1.

[0089] The driving shaft 30 is of a double - threaded structure, and the two driving blocks 31 are symmetrically arranged on the driving shaft 30.

[0090] During specific implementation, the driving motor 34 is started, and the driving motor 34 rotates forward and backward. The driving motor 34 drives the driving shaft 30 to rotate. Since the driving shaft 30 is of a double - threaded structure, when the driving shaft 30 rotates, the two driving blocks 31 always move synchronously along the driving shaft 30, and the two driving blocks 31 approach and move away synchronously. During this process, the spray shower 33 will reciprocally move along the width direction of the working box 1. And when the spray shower 33 reciprocally moves, it sprays the disinfectant liquid onto the bearing tray 212 to disinfect the instruments on the bearing tray 212.

[0091] It should be noted that two groups of spray showers 33 are provided. One group disinfects the top of the bearing tray 212, and the other group disinfects the bottom of the bearing tray 212.

[0092] Finally, the instrument moves to a specified position inside the working box 1 for drying treatment. After it is dried, the cover plate 14 corresponding to the material taking slot 13 is opened, and it can be taken out.

[0093] Embodiment 3: On the basis of Embodiment 1, in order to ensure the efficiency of instrument cleaning and sterilization, the present application also proposes a damping block 52.

[0094] Looking back Figure 4 and Figure 5As shown in the figure, damping grooves 50 are provided on both sides in the width direction of the bearing pallet 212. Damping springs 51 are installed in the damping grooves 50. Damping blocks 52 are slidably installed on the damping springs 51. One side of the damping blocks 52 abuts against the inner wall of the bearing frame 210.

[0095] In the initial state, the damping blocks 52 abut against the inner wall of the bearing frame 210 under the extrusion of the damping springs 51, so that the bearing pallet 212 always maintains a horizontal state, avoiding the situation that the bearing pallet 212 tilts due to the uneven weight distribution after fixing multiple instruments on it, thereby improving the stability of the entire bearing pallet 212.

[0096] After different types of instruments are installed and positioned on the upper end surface of the bearing pallet 212, actively press one side of the bearing pallet 212 to make the bearing pallet 212 rotate 180 degrees around the positioning post 211, so that the side with the limited fixed instrument faces down, and the other side of the bearing pallet 212 flips to the top. At this time, instruments can be continuously limited and fixed on the other side, so that both sides of the bearing pallet 212 are limited and fixed with multiple instruments, thereby greatly increasing the number of instruments limited and fixed, enabling them to be disinfected and sterilized synchronously, and ensuring the efficiency of disinfection and sterilization. If the instruments are processed one by one, it will cause the disinfection and sterilization time of the instruments to be greatly extended, resulting in a large amount of time occupied by the disinfection and sterilization of the instruments, and unable to ensure the supply and use of subsequent instruments.

[0097] During operation: First step, move the working box 1 to the designated position, open the cover plate 14 on the feeding slot 12, place the instrument to be processed (such as a surgical knife handle) on the upper end surface of the bearing platform 21, and place multiple instruments reasonably on the top of the bearing pallet 212 according to their specific shapes.

[0098] Second step: Then pick up the limiting fork 60 and press the control rod 62 at the top of the limiting fork 60. The limiting block 66 retracts into the limiting fork 60. At this time, the outer walls at both ends of the limiting fork 60 are smooth without any protrusions. Then insert the limiting fork 60 into the hollow hole 213 on the bearing pallet 212 until the limiting block 66 is inserted into the clamping hole 68 in the hollow hole 213 of the bearing pallet 212, and the fixation of the instrument by the limiting fork 60 can be realized.

[0099] Third step: Multiple limiting forks 60 can be used for the same instrument as needed to ensure the stability of the connection between the instrument and the bearing pallet 212.

[0100] Step 4: After different types of instruments are installed and positioned on the upper end surface of the bearing pallet 212, actively press one side of the bearing pallet 212, so that the bearing pallet 212 rotates 180 degrees with the positioning post 211 as the center, making the side with the limited and fixed instrument face downward, and the other side of the bearing pallet 212 flips to the top. At this time, the instrument can be continuously limited and fixed on the other side, so that both sides of the bearing pallet 212 limit and fix multiple instruments, thereby greatly increasing the number of instruments limited and fixed.

[0101] Step 5: After the instrument is fixed on the bearing pallet 212, start the conveying device 2, and the conveying chain 20 on the conveying device 2 rotates. The conveying chain 20 drives the bearing pallets 212 on both sides along the movement track of the conveying chain 20, driving them to pass through the cleaning area 10 and the disinfection and sterilization area 11 in sequence, and then taking them out from the material taking slot 13 of the working box 1 after drying.

[0102] Step 6: When the bearing pallet 212 moves to the cleaning area 10 inside the working box 1, the electric push rod 41 is started. The output end of the electric push rod 41 drives the cleaning box 40 to approach the bearing pallet 212 until the cleaning box 40 is sleeved around the bearing pallet 212. Subsequently, a large amount of dissolving liquid is poured out from the cleaning pipeline 42 at the top of the cleaning box 40 onto the surface of the instrument from top to bottom, and a large amount of dissolving liquid is sprayed from the cleaning pipeline 42 at the bottom of the cleaning box 40 onto the surface of the instrument from bottom to top. After the dissolving liquid is sprayed, clean water can be sprayed through the cleaning pipeline 42 to wash away the dissolving liquid and stains, ensuring the cleanliness of the instrument.

[0103] Step 7: After the instrument is cleaned in the cleaning area 10, the instrument moves to the disinfection and sterilization area 11. Start the driving motor 34, and the driving motor 34 drives the driving shaft 30 to rotate. The driving shaft 30 is provided with an eight-shaped reciprocating thread groove. When the driving shaft 30 rotates, the driving block 31 reciprocates along the driving shaft 30. During this process, the spray shower 33 will reciprocate along the width direction of the working box 1, and when the spray shower 33 reciprocates, disinfectant liquid is sprayed onto the bearing pallet 212 to disinfect the instruments on the bearing pallet 212.

[0104] Step 8: Subsequently, the instrument moves to a designated position inside the working box 1 for drying treatment. After it is dried, open the cover plate 14 corresponding to the material taking slot 13 and take it out.

[0105] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
