Description

Technical Field

[0001] This utility model relates to the field of personal safety protective equipment, and in particular to a preventive wearable automatic fall protection device. Background Technology

[0002] Falls are a major safety risk for the elderly, people with mobility impairments, those suffering from sudden cardiovascular and cerebrovascular diseases, and travelers. They can lead to fractures in the arm, spine, and hip, as well as serious brain injuries. The elderly, in particular, experience a decline in physical function with age, weakened muscle strength, and significantly reduced balance and reaction time. Furthermore, age-related osteoporosis makes their bones fragile and brittle. A fall can result in serious injuries, bedridden conditions requiring long-term care, and even death. Such falls place a heavy burden on families, incurring high medical and rehabilitation costs, requiring significant time and energy from caregivers, and impacting family income and mental well-being.

[0003] Existing technologies have gradually developed protective solutions for this area. While they achieve a certain level of protection, they still have some shortcomings and deficiencies. For example, most wearable fall protection devices currently available use electronic circuitry control and are equipped with accelerometers or weightlessness sensors and gyroscopes to monitor the wearer's body movement in real time. When an abnormal change in body posture is detected and the acceleration exceeds a set threshold, a gas generator is quickly triggered. Immediately, protective airbags corresponding to important body parts (such as the hips, chest, back, arms, and head) deploy instantly, forming a buffer layer before the body contacts the ground or other objects, effectively reducing impact and protecting important body parts from serious injury. However, the drawbacks of this type of wearable fall protection device are also quite obvious. 1) Electronic circuit control relies on electronic components, which are easily affected by low temperature, high temperature, or humid environments, leading to decreased stability, equipment failure, and inability to monitor and trigger protection normally; 2) Accelerometers and gyroscopes are prone to misjudgment in special scenarios, such as riding in bumpy vehicles or making large twisting movements, which may misinterpret normal movements as a fall, incorrectly deploying airbags, disrupting daily life, wasting gas generator energy, and incurring high replacement costs; 3) The protective device relies on electricity and requires regular charging. When there is a power shortage or insufficient power, the protective device may fail due to lack of power at critical moments; 4) The gas generator is a disposable consumable. If it malfunctions or runs out of energy, the airbag may fail to inflate, thus losing its protective function; 5) The protective device has complex functional modules, high research and development and production costs, and a high price. Many families who need it do not purchase it due to the price, hindering the popularization of this type of product; 6) The protective device is highly integrated with wearable equipment, cannot be easily disassembled and installed, is not flexible in use, and is difficult to clean, which can easily damage the internal electronic and mechanical components. The two patent documents disclosed below each contain the aforementioned defects and deficiencies.

[0004] Chinese utility model patent specification (publication number: CN215837202U) discloses a concealed wearable airbag. Its working principle involves a first airbag 21 folded inside a first bag body 2, and a second airbag 22 folded inside a second bag body 3. A gyroscope sensor collects human posture data in real time and transmits this data to a microprocessor for analysis. When the detected human posture data matches the characteristics of a fall, the microprocessor sends a signal to control a gas generator 4 to release gas and quickly fill the airbag, allowing the airbag to smoothly eject from the garment body 1, thereby ensuring the safety of the wearer.

[0005] Chinese utility model patent specification (publication number: CN220308487U) discloses a fall protection device. Its working principle is that the hook 16 and the hook bolt 17 are used to wear the circular hoop 1 on the human head. When the weightlessness sensor 3 senses that the human body has fallen, it transmits an air intake command to the air intake component 4. The suction fan 41 pumps the intake air through the ventilation pipe 42 to the airbag 22. The airbag 22 quickly inflates and pops out from the receiving cavity 21 to protect the human head.

[0006] In view of this, the inventor, drawing on years of experience in the field of personal safety products and equipment, designed and improved the product by considering structural optimization and through numerous experiments and improvements. Summary of the Invention

[0007] To address the shortcomings and deficiencies of the existing technology, this utility model provides a preventative wearable automatic fall protection device. This device employs a detachable wearable structure, allowing it to attach to corresponding parts of wearable components and adapt to different types of wearable devices. Simultaneously, by utilizing the air-storage and compression functions of the air supply bladder, combined with the natural flow of gas between bladders due to pressure differences, a dynamic pressure gradient is formed. The air supply bladder first provides initial cushioning, and then the pop-out bladder instantly deploys to provide secondary protection, thus providing secondary cushioning protection to the corresponding parts of the body in accordance with the laws of mechanical cushioning.

[0008] To achieve the above objectives, this utility model provides an automatic fall protection device, including an air supply airbag, a pop-out airbag, and a storage bag. The air supply airbag is equipped with an inflation / deflation nozzle and is filled with atmospheric pressure air as an air source. The pop-out airbag is connected to the air supply airbag and can be folded, rolled up, stored, and inflated to pop out. The storage bag has a receiving area for accommodating the folded pop-out airbag and a fixing component. The receiving area is connected to one end of the pop-out airbag. One end of the fixing component is fastened to one side of the receiving area, and the other end spans the receiving area and is connected to the other side of it via a buckle assembly. The opening and closing force of the buckle assembly is less than the pop-out force of the pop-out airbag. The air supply airbag, the storage bag, and the wearable components are equipped with detachable connection components at corresponding positions.

[0009] The present invention further provides an automatic fall protection device, which also includes a split airbag. The split airbag is filled with normal pressure air as an air source. The split airbag is connected to any one of the following: a deflation airbag, other split airbags, and a pop-out airbag. Each split airbag is also provided with a detachable connection component at the corresponding position of the wearable component.

[0010] The present invention further provides an automatic fall protection device, wherein the fixing component is a movable cover that covers the receiving area.

[0011] This utility model further provides an automatic fall protection device, wherein the fastener assembly is any one of Velcro, snap fastener, and magnetic snap.

[0012] This utility model further provides an automatic fall protection device, wherein the detachable connecting component is any one of Velcro, snap fasteners, and zippers.

[0013] This utility model further provides an automatic fall protection device in which the wall thickness of the air supply bladder is smaller than the wall thickness of the ejection bladder.

[0014] The present invention further provides an automatic fall protection device in which the surface of the air supply airbag, the ejection airbag and the distribution airbag are all covered with a layer of puncture-resistant fabric.

[0015] The present invention further provides an automatic fall protection device in which the pop-out airbag and the supply airbag are connected by an elastic rubber tube, and the connection between the elastic rubber tube and the two airbags is an interference fit. At the same time, the elastic rubber tube and the connection are provided with a concave-convex surface buckle for locking.

[0016] The aforementioned automatic fall protection device mainly consists of a supply airbag and a deployment airbag working together. The supply airbag is the primary buffer, responsible for pre-storing and releasing gas, while the deployment airbag acts as a secondary buffer, protecting other critical parts of the body. The two are connected by an air supply tube, enabling gas transfer and exchange between the airbags and creating a pressure difference. Both the supply airbag and the storage bag have detachable connecting components on their backs, allowing for flexible installation and replacement on wearable devices. The supply airbag is worn on the part of the body that first impacts during a fall, such as the buttocks, abdomen, and back. The deployment airbag is normally folded and stored in the storage bag, which, using the detachable connecting components, can be flexibly installed to protect the waist, head, and chest. When a person falls, based on the inertial landing posture and interval, the supply airbag on the first point of impact will collide with the ground first and be instantly compressed, providing immediate cushioning protection to that area. During this process, the gas inside the supply airbag is compressed and released, rapidly flowing into the ejection airbag through the air supply tube. This causes a rapid increase in air pressure inside the folded and rolled-up ejection airbag, breaking free from the restraining force and creating a spring-like cushioning effect, allowing for instantaneous ejection. This provides cushioning protection for areas of the body that may subsequently experience secondary impact (such as the head and waist). Once the pressure is released, the ejection airbag can refill the supply airbag with residual air during its folding and rewinding process, eliminating the need for frequent inflation. Throughout the entire process, the supply and ejection airbags each perform their respective functions, effectively cushioning and protecting the corresponding parts of the body.

[0017] Compared to existing technologies, this invention utilizes the principle of gas transfer and exchange between airbags through collision and compression. Combined with a detachable connecting component, it provides effective cushioning protection in stages, according to the sequence of impact points during a fall. This significantly reduces the risk of severe injury or even death to critical body parts after a fall, providing strong protection for the user's safety. From a structural and performance perspective: First, the device has a simple structure, low operating cost, and is easy to promote. It is stable, reliable, and safe, requiring no complex electronic circuit control or gas generator supply. The gas used can be circulated between the airbags, eliminating concerns about gas generator malfunction or energy depletion. Second, because it does not rely on electronic components, it avoids the impact of low temperature, high temperature, or humid environments on component performance. It can operate stably and perform its protective function normally in various operating environments, exhibiting strong overall environmental adaptability and higher stability, reducing the false alarm rate. Third, it requires no charging, eliminating battery anxiety. In terms of ease of use, its detachable connecting component can be flexibly installed and disassembled according to the needs of the protected body parts. After separation, it also facilitates cleaning of the wearable items, greatly improving the flexibility and convenience of daily use. In addition, this device has another practical function: when accidentally falling into the water, the built-in airbags can create a buoyancy effect similar to a life jacket, buying crucial time for rescue.

Detailed Implementation

[0026] To make the invention objective, technical solution and beneficial effects of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0027] like Figures 1-5 As shown in the figure, this embodiment provides an automatic fall protection device, which mainly consists of an air supply airbag, a pop-out airbag, a storage bag, a distribution airbag and a deflation airbag. Each component works together with the gas flow path through a specific connection structure. The specific implementation method is as follows.

[0028] like Figure 1As shown, the air supply airbag 1 is responsible for gas storage and output. It is also the main airbag providing crucial cushioning protection for the first part of the body to hit the ground after a fall. Its placement is primarily on the buttocks, abdomen, and back—critical areas where the body is likely to make initial contact with the ground and require focused protection. The air supply airbag is made of high-molecular-weight thermoplastic polyurethane elastomer (TPU), a material with good elasticity, abrasion resistance, oil and water resistance, excellent mechanical strength, impact resistance, high stability, and is non-toxic, environmentally friendly, and recyclable. In terms of shape design, the air supply airbag is based on a flat square shape. In addition, the air supply airbag can be designed in common geometric shapes such as circles, triangles, trapezoids, and hexagons, or a curved surface designed to conform to the curve of the first part of the body to achieve more comprehensive, effective, and accurate cushioning protection. The surface of the air supply airbag is equipped with an inflation / deflation nozzle 2 for connecting an external inflation device. There are two options for the external inflation device: one is a manual inflation / deflation mechanism, such as the hand-operated bulb inflation method on a blood pressure monitor, which allows for easy and flexible operation by the user; the other is an electric inflation pump, which provides more convenient, labor-saving, and efficient inflation. With these external inflation devices, gas can be pre-filled into the air supply bladder via the inflation / deflation nozzle and stored, or the gas can be released through the deflation nozzle. Once the air supply bladder is inflated, it does not need to be re-inflated, as the gas can be recycled. However, the inflated air supply bladder is in an inflated state. In this inflated state, if a person falls, the air supply bladder will be compressed and deflated, providing initial cushioning protection. Furthermore, in use, the air supply bladder is filled with normal-pressure air as its gas source, which is safer than high-pressure gas sources and nitrogen cylinders, and can meet the safety requirements of people in public places such as airplanes and high-speed trains.

[0029] The ejection airbag 4 is a pop-out component that provides protection for the secondary impact site after a person falls. Its volume is smaller than the supply airbag, and it is normally uninflated. This ejection airbag is mainly used to protect vital areas such as the waist and head when a person falls, and can be placed below these areas. The ejection airbag is connected to the supply airbag via an air supply pipe 3. This air supply pipe is made of elastic rubber. During connection, both ends of the elastic rubber pipe are respectively press-fitted to the air inlet 5 of the ejection airbag and the inflation / deflation nozzle 2 of the supply airbag for quick disassembly; alternatively, a separate exhaust nozzle can be added to the supply airbag for separate press-fitting to the air supply pipe. However, in this embodiment, the supply airbag uses an inflation / deflation nozzle that simultaneously functions as both an inflation nozzle and an exhaust nozzle. Regarding material selection, the ejection airbag is made of the same high-molecular-weight thermoplastic polyurethane elastomer (TPU) material as the supply airbag. In terms of shape design, the pop-out airbag adopts a rectangular shape for easy folding and storage. When not inflated, it can be folded and rolled up for storage in the accompanying storage bag. Figure 1 The diagram illustrates the transformation of a folded, rolled-up ejection airbag into its inflated, ejected state. Furthermore, the shape of the ejection airbag can be optimized with ergonomic curves or wrap-around designs to better fit the protected area. Through this structure, when the supply airbag is compressed and deflated, airflow instantly fills the ejection airbag through the air delivery pipe, causing a rapid increase in internal pressure and quickly expanding the airbag to form a protective barrier. Conversely, when the ejection airbag folds, its internal gas automatically flows back to the supply airbag through the air delivery pipe, achieving dynamic pressure balance and gas recycling.

[0030] Furthermore, to enhance the stability of the connection between the air supply pipe and the air inlet 5 of the deployment airbag and the inflation / deflation nozzle 2 of the air supply airbag, and to prevent the air supply pipe from easily loosening during use, the inner and outer walls of their connection points adopt a matching concave-convex connection structure (not shown in the figure). Specifically, the inner wall of both ends of the air supply pipe connection port is provided with a ring-shaped convex ring, while the outer wall of the air inlet and inflation / deflation nozzles is provided with a corresponding ring-shaped concave ring of suitable depth and width. When the air supply pipe is inserted into the interface, the convex ring will embed into the concave ring under pressure, forming a physical latch, thereby improving the connection's resistance to pull-out. In addition, in this embodiment, a clamp can be added at the interface for auxiliary locking.

[0031] like Figure 2As shown, the storage bag is a component of the ejector airbag 4. It serves both to store the folded and rolled-up ejector airbag and to attach it to the wearable device, thus combining storage and attachment functions. The storage bag is designed as an unfoldable "cloth" shape, made of nylon or canvas, and wider than the ejector airbag to provide ample space for containment and wrapping. The central part of this "cloth"-shaped storage bag has a receiving area 6 for housing the ejector airbag, as well as a fastener for temporarily securing the airbag. After folding and rolling, the ejector airbag can be placed within the receiving area, and the fastener effectively restrains it. The receiving area is fixedly connected to one end of the ejector airbag (usually the air inlet 5 side) by stitching or heat fusion, and the ejector airbag can be placed on the receiving area in a folded and rolled-up manner. The stitching connection between the receiving area and the ejector airbag prevents the airbag from floating up after deployment, detaching from the preset protection area, and thus reducing the protective effect due to deviation of the protected area. The fastener is a strip-shaped fastening strap 7. One end of the strap is sewn to one side of the receiving area, and the other end crosses the receiving area and connects to the other side of the receiving area via a hook-and-loop fastener assembly to achieve temporary restraint and release of the airbag. This fastening assembly uses a Velcro structure 8, and the opening and closing force of the Velcro structure is set to be less than the opening force of the airbag. This design ensures that the airbag can break free from restraint and deploy normally when stored. Furthermore, two fastening straps can be used to further enhance the stability of the stored state through double restraint.

[0032] like Figure 3 As shown, in the second embodiment of the storage bag, the basic "cloth-wrapping" structure is continued, but a simpler fixing method is adopted. This design uses one side of the "cloth-wrapping" storage bag as a foldable cover 9. In use, this cover can be folded directly onto the other side of the storage bag, thus wrapping the folded and rolled-up pop-up airbag. This foldable cover also functions as a fastener, using Velcro 8 for quick temporary fixing and loosening. This design allows for convenient temporary restraint and loosening of the folded and rolled-up pop-up airbag, simplifying the overall structure of the storage bag while maintaining ease of operation.

[0033] like Figure 4As shown, in the third embodiment of the storage bag, the storage bag adopts a "bag"-shaped structure design. This "bag"-shaped storage bag has a bag opening 10, with a corresponding pocket 11 inside serving as a storage area. The pocket size is adapted to the pop-out airbag, allowing it to be used to store the folded and rolled-up pop-out airbag, with the air inlet end of the pop-out airbag sewn to the bottom of the pocket. A Velcro structure 8 is provided at the bag opening as a fastening assembly, which can temporarily lock the pop-out airbag inside the pocket, preventing it from accidentally unfolding when not in use. Furthermore, this embodiment also includes another design solution: changing the closure method of the bag opening to a flip-over cover type, that is, by setting a flip-over cover to cover the bag opening, and then using a Velcro structure to connect and fix the bag opening.

[0034] The buckle assembly of the aforementioned storage bag (not shown in the figure) can be connected using Velcro, with the hook and loop sides engaging, or via snap fasteners or magnetic clasps. Snap fasteners secure the bag by interlocking male and female snaps; magnetic clasps rely on magnetic attraction for a smoother opening and closing process. Alternatively, the magnetic clasp design can use a raised surface and a corresponding recessed surface, with a raised structure on one side and a matching recessed structure on the other, allowing for precise magnetic attraction through the precise interlocking of the protrusion and recess. However, regardless of the connection method chosen, it is crucial to ensure that the opening and closing force of the buckle assembly is less than the pop-out force of the airbag to guarantee smooth deployment when needed.

[0035] like Figure 5 As shown, the air bladder 12 is mainly used for supplying air and for covering critical parts of the human body not covered by the main air bladder. It can serve as a secondary air bladder to the main air bladder, offering greater flexibility in use. The air bladder needs to pre-store a certain amount of atmospheric pressure air as its air source and is typically positioned around the hip bones and shoulders. The air bladder is designed to cover the hip bones or shoulders in a curved shape, such as a shield or a curved shape, and uses the same material as the supply air bladder. The air bladder is also connected to a deflation bladder 13, which is connected via an interference fit using an elastic rubber tube, thus forming a pressure regulation system. Under normal conditions, the deflation bladder is uninflated. When the air bladder is impacted and compressed, the compressed gas is quickly transferred to the deflation bladder, which absorbs the pressure from the air bladder. This design prevents the air bladder from bursting due to excessive pressure and also prevents the rigid air bladder from causing secondary damage to the protected areas, thus achieving an ideal cushioning protection effect. This pressure transfer mechanism ensures that the airbags maintain appropriate flexibility when subjected to impact, providing safe and reliable protection for the human body.

[0036] In another embodiment of the airbag system, the airbag is connected to another adjacent airbag or the deployment airbag via a connecting tube. This connection utilizes a combination of a supply airbag and a deployment airbag, employing a flexible rubber tube with a snap-fit ​​structure. When an airbag is compressed, its internal gas can be rapidly transferred to other connected airbags. This dynamic pressure distribution mechanism significantly improves the cushioning performance of the compressed airbag and achieves pressure equalization within the airbag system, providing more uniform and effective all-around protection for the human body. Furthermore, the airbag system can connect with multiple airbags to form a pressure regulation system. When any airbag is impacted and compressed, the compressed gas can be rapidly transferred to other connected airbags, where these components absorb the pressure from the compressed airbag.

[0037] like Figure 6 As shown, the back of components such as the air supply airbag, storage bag, and air distribution airbags are equipped with detachable connecting components that connect to the wearable device. These detachable connecting components utilize the aforementioned Velcro structure 8, consisting of a hook side 8a and a loop side 8b. During installation, the hook side is fixed to the back or front of the air supply airbag, storage bag, and air distribution airbag, while the loop side is fixed to the corresponding part of the wearable device. The two sides are bonded together to achieve a secure connection between the airbag components and the wearable device. Furthermore, the positions of the hook and loop sides of the Velcro structure can be interchanged; that is, the loop side can also be fixed to the back of the air supply airbag, storage bag, and air distribution airbag, while the hook side is correspondingly positioned on the wearable device, achieving the same reliable connection.

[0038] In other embodiments of the detachable connecting assembly (not shown in the figure), besides the Velcro structure, alternative solutions such as snap fasteners or zippers can also be used. Snap fasteners, also known as male-female snaps, flap snaps, or snap buttons, involve fixing an appropriate number of male snaps to the back of components such as the air supply bladder, storage bag, and air distribution bladders, while the corresponding female snaps are placed on the corresponding parts of the wearable components. Quick connection is achieved through the interlocking of the male and female snaps. When using a zipper structure, it consists of a toothed band and a zipper pull. One side of the main toothed band is sewn to the back of each air bladder component, and the other side of the secondary toothed band is fixed to the corresponding parts of the wearable components. Opening and closing operations are completed by sliding the zipper pull, thus achieving connection and separation. Similar to the Velcro structure, the installation positions of the mating components of snap fasteners or zippers can also be interchanged. That is, the female snap of the snap fastener can be fixed to the back of each component, and the male snap can be placed on the wearable item; or the toothed bands on both sides of the zipper can be swapped, both achieving a stable connection.

[0039] More preferably, the wall thickness of the supply airbag is less than that of the deployment airbag. This design results in a higher pressure inside the deployment airbag compared to the supply airbag, creating a pressure difference. When the deployment airbag is in its unfolded, coiled state, the gas inside can automatically flow back to the supply airbag using this pressure difference, which helps to accelerate the folding and coiling process. Furthermore, this airbag wall thickness difference design also applies to the coordination of the distribution airbag with other related airbags: pressure gradients can be created between the distribution airbag and the deflation airbag, between the distribution airbag and another distribution airbag, and between the distribution airbag and the deployment airbag by setting reasonable wall thickness differences, ensuring that gas flows in the desired direction between different airbags.

[0040] More preferably, the surfaces of the supply airbag, deployment airbag, and dispensing airbag are all covered with a layer of puncture-resistant fabric. For the general population, who are often in environments with broken glass, sharp stones, branches, thorns, and debris, the puncture-resistant fabric is made of soft ultra-high molecular weight polyethylene fiber, polyester fiber, high-density fabric, etc. For environments such as tourism, mountaineering, sports, and disaster relief, the puncture-resistant fabric is made of high-strength polyamide fiber, high-density carbon fiber, aramid fiber, thickened fabric, etc. This puncture-resistant fabric is woven from the above materials and firmly bonded to the airbag substrate through a hot-pressing composite process. This design effectively improves the puncture resistance while maintaining the original flexibility of the airbag, preventing sharp objects from puncturing the airbag.

[0041] The aforementioned wearable components mainly refer to common clothing and accessories that can be worn or attached to the human body, such as tops, pants, belts, chest straps, backpacks, and waist bags. These items can be pre-integrated or sewn with matching, detachable connecting components (i.e., hook and loop, male and female buckles, main and auxiliary toothed straps) at the corresponding parts of the body requiring protection. For example: around the collar, shoulders, front abdomen, and back of tops; the back and sides of pants, and below the back of the cuffs. This design allows for modular installation and disassembly of components such as air supply bladders, deployment bladders, storage bags, and distribution bladders, making operation convenient and simple, and increasing flexibility. Furthermore, the connection between air supply bladders, deployment bladders, and distribution bladders can be achieved through short-path connections using the nearest available method to accelerate gas conversion.

[0042] like Figure 6 , Figure 7As shown, taking clothing as an example, on the inner or outer side of the top 14, corresponding to the abdomen, back, shoulders, and around the neckline, there are Velcro-structured rough surfaces 8a, and on the back or front of the abdominal airbag 1a, back airbag 1b, shoulder airbags 12a, first storage bag 16, and second storage bag 17, there are Velcro-structured hook surfaces 8b. By attaching the rough and hook surfaces, these airbags can be easily fixed to the corresponding positions on the top. The first and second storage bags 16 and 17 are respectively located at the front and lower back of the neckline. The first and second storage bags also contain two pop-up airbags: a face airbag 4a and a back-of-the-head airbag 4b, which together form the head protection pop-up airbag. When connected, the abdominal airbag is connected to the face airbag, and the back airbag is connected to the back-of-the-head airbag, ensuring rapid air supply to the head protection pop-up airbags when needed. Each shoulder airbag 12a has a connected de-airbag, or they can all connect to the same de-airbag to adjust pressure during shoulder protection. On the inner or outer side of the pants 15, corresponding to the buttocks, hip bones, and lower back of the hem, there are Velcro-fastened rough surfaces 8a, and on the back or front of the buttocks airbag 1c, hip bone airbags 12b, and the third storage pocket 18, there are Velcro-fastened hook surfaces 8b. These airbags can be easily secured to the corresponding positions on the pants by attaching the rough and hook surfaces. The third storage pocket 18 is located at the lower back of the hem. The third storage pocket contains a lumbar support pop-up airbag 4c. When connected, the buttocks airbag 1c is connected to the lumbar support pop-up airbag 4c to provide timely air supply to the lumbar support pop-up airbag. Each hip bone airbag has a connected de-airbag, or they can all connect to the same de-airbag to adjust pressure during hip protection.

[0043] Based on the implementation of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
