[0009] Specifically, the wristband further includes multiple first telescopic rods, multiple second telescopic rods, multiple first rotating shafts, multiple second rotating shafts, and multiple third rotating shafts. One end of each of the first and second telescopic rods is rotatably mounted on a first rotating shaft, and the other end of each of the first and second telescopic rods is rotatably mounted on a third rotating shaft. The other end of each of the second telescopic rods is rotatably mounted on an adjacent third rotating shaft.

[0016] This invention, by adopting the above technical solutions, has significant technical effects:

[0017] First, the wristband is worn on the arm. When the first screw is rotated, the first push-pull ring moves, which in turn drives the first push-pull rod to move. The first push-pull rod then drives the cavity rotating rod to rotate, changing the flared angle of the protective component and thus altering the protection range. When the second screw is rotated, the second push-pull ring moves, which in turn drives the second push-pull rod to move. The cavity rotating rod and the cavity sliding rod are slidably positioned together. The second push-pull rod drives the cavity sliding rod to slide on the cavity rotating rod. During the sliding process, the cavity sliding rod causes the telescopic fabric to extend and retract, further changing the protection range. The changes in the flared angle and length allow for diverse changes in the protection range, which can be adjusted arbitrarily according to different situations. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention is further described below in conjunction with specific embodiments. The following embodiments are explanations of the invention, but the invention is not limited to the following embodiments.

[0028] Example:

[0029] like Figures 1-8 As shown, the protective device of the present invention includes a wristband 1, an air intake component 2, a backwash component 3, and a protective component 4. The protective component 4 is trumpet-shaped. The wristband 1 includes an inner ring 11 and an outer ring 12. One end of the protective component 4 is disposed on the outer ring 12.

[0030] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 The protective assembly 4 shown includes a telescopic fabric 41, a first screw 42, a second screw 43, multiple cavity sliding rods 44, multiple cavity rotating rods 45, a first push-pull ring 46, a second push-pull ring 47, multiple first push-pull rods 48, and multiple second push-pull rods 49. The first push-pull ring 46 and the second push-pull ring 47 are simultaneously slidably disposed on the outer ring 12 and located at both ends of the outer ring 12. The two ends of the telescopic fabric 41 are respectively disposed on the outer ring 12 and the cavity sliding rods 44. One end of the cavity rotating rod 45 is rotatably disposed between the outer ring 12 and the cavity rotating rod 45. The cavity sliding rod 44 and the cavity rotating rod 45 are slidably connected. The rotating rod 45 with cavity has multiple small holes. The rotating rod 45 with cavity has a through hole 7 that communicates with the cavity of the sliding rod 44 with cavity. The two ends of the first push-pull rod 48 are respectively rotatably mounted on the first push-pull ring 46 and the rotating rod 45 with cavity. The two ends of the second push-pull rod 49 are respectively rotatably mounted on the second push-pull ring 47 and the sliding rod 44 with cavity. The first screw 42 is rotatably mounted on the outer ring 12 and cooperates with the first push-pull ring 46. The second push-pull ring 47 is provided with a clearance hole 51. The first screw 42 passes through the clearance hole 51. The rotation of the first screw drives the first push-pull ring but does not drive the second push-pull ring to move. The second screw 43 is rotatably mounted on the outer ring 12 and cooperates with the second push-pull ring 47. Rotating the first screw drives the first push-pull ring on the outer ring. The movement of the first push-pull ring drives the first push-pull rod to push and pull. The push-pull rod 48 pushes and pulls the cavity rotating rod, causing the cavity rotating rod to rotate, thereby changing the size of the bell mouth of the protective component and changing the protection range. Rotating the second screw drives the second push-pull ring 47 on the outer ring. The movement of the second push-pull ring 46 drives the second push-pull rod to push and pull. The push-pull rod 49 pushes and pulls the cavity sliding rod, causing the cavity sliding rod to slide on the cavity rotating rod. The cavity sliding rod drives the telescopic fabric 41 to extend and retract, changing the size of the protection area again. The small holes 50 on the cavity rotating rod and the cavity sliding rod are used to collect the splashed liquid. The cavity rotating rod and the cavity sliding rod 44 are connected through the through hole 7.

[0031] Furthermore, a plurality of the cavity rotating rods 45 are arranged in an equidistant ring on the outer ring, a plurality of cavity sliding rods 44 correspond one-to-one with a plurality of cavity rotating rods 45, and a plurality of first push-pull rods 48 and a plurality of second push-pull rods 49 correspond one-to-one with a plurality of cavity rotating rods 45.

[0032] Furthermore, such as Figure 6 The diagram shows the structure of the wristband 1. The wristband 1 also includes multiple first telescopic rods 13, multiple second telescopic rods 14, multiple first rotating shafts 15, multiple second rotating shafts 16, and multiple third rotating shafts 17. One end of each of the first and second telescopic rods 14 is rotatably mounted on a first rotating shaft 15. The other end of each of the first telescopic rods 13 is rotatably mounted on a third rotating shaft 17. The other end of each of the second telescopic rods 14 is rotatably mounted on an adjacent third rotating shaft 17. The first and second telescopic rods 14 are rotatably connected via second rotating shafts 16 and are symmetrically arranged. The first rotating shafts are rotatably mounted on the outer ring 12. The wristband is an airbag-type structure with a closed internal space, allowing for easy expansion and contraction and fixation to the wrist. The wristband will not cause any pressure on the arm. The outer ring is made of a rigid material, making the protective device less prone to deformation during use. The inner ring 11 is made of a soft material, which can freely stretch and contract with the size of the arm, making it convenient for the user to wear. After the user wears it on the arm, it has a certain binding effect on the arm, which provides a soft fixation effect. The first telescopic rod 13, multiple second telescopic rods 14, multiple first rotating shafts 15, multiple second rotating shafts 16, and multiple third rotating shafts 17 outside the inner ring 11 are arranged in coordination with each other. After being worn on the arm, they generate an inward pushing force, which clamps the wristband on the arm, providing a rigid fixation effect. This makes the wristband and the protective device on the wristband less likely to loosen after being worn on the arm, greatly improving the fixation effect.

[0033] Furthermore, such as Figure 3 As shown, a cavity 5 is provided at one end of the outer ring. Multiple fine water pipe holes 6 are arranged in an equidistant ring array on the outer ring and are connected to the cavity 5. The multiple fine water pipe holes are arranged one-to-one with the multiple rotating rods 45 with cavities. A connecting hole 8 is also provided on the outer ring. The fine water pipe holes 6 and the rotating rods 45 with cavities are connected through a transmission pipe 23. Blood and body fluids sucked into the cavity by the small hole 50 are transferred to the fine water pipe holes 6 through the transmission pipes. Blood and body fluids sucked into the transmission pipes are transferred into the cavity through the fine water pipe holes. The liquid is sucked out of the cavity through the first connecting pipe connected through the connecting hole 8.

[0034] Furthermore, such as Figure 2As shown, the suction assembly includes a suction pump 21, a three-way valve 22, a first connecting pipe 24, and a second connecting pipe 25. The first connecting pipe 24 is installed at both ends on the three-way valve 22 and the suction pump 21, respectively, and is used to connect the suction pump 21 to the three-way valve 22. The second connecting pipe 25 is installed at both ends on the connecting hole 8 and the three-way valve 22, respectively, and is used to connect the three-way valve to the cavity 5. When performing suction operation on the protective assembly 4, the suction pump 21 is turned on. Inhale, open the three-way valve connecting the first connecting pipe end and the second connecting pipe end. The second connecting pipe is connected to cavity 5. The thin water pipe hole 6 is connected to the cavity. The thin water pipe hole is connected to the rotating rod with cavity through transmission pipe 23. Because cavity 5 has strong sealing, when inhaling, the small hole 50 on the rotating rod with cavity 45 will feel a large suction force, drawing the liquid splashed on the rod or even the telescopic fabric into the cavity; and because the sliding rod with cavity 44 is set on the rotating rod with cavity 45 and slidably connected to it, Figure 5 As shown, the rotating rod with cavity has a through hole that communicates with the cavity of the sliding rod with cavity. In this way, the small hole 50 on the sliding rod with cavity 44 will also feel the suction force, which will draw the blood and body fluids splashed on the rod and the telescopic fabric into the cavity of the sliding rod with cavity. Since the cavities of the sliding rod with cavity and the rotating rod with cavity are connected and connected to the transmission pipe 23, the transmission pipe will draw the blood and body fluids into the cavity 5 and then discharge them.

[0035] Furthermore, such as Figure 2As shown, after the protective device is used, in order to facilitate the next use and ensure the cleanliness of the device, the device is equipped with a backwashing assembly. The backwashing assembly includes a third connecting pipe 31, one end of which is equipped with a water pump, and the other end of which is installed on the three-way valve. During the backwashing process to clean the protective assembly, the end of the three-way valve 22 connected to the second connecting pipe and the end connected to the third connecting pipe are opened to allow water to pass through the valve. Due to the strong sealing of the cavity, water can only enter the thin water pipe hole 6 from the cavity 5. The water is transported to the cavity of the rotating rod 45 through the transmission pipe 23 connected to the cavity rotating rod 45. The cavity sliding rod and the cavity rotating rod 45 are slidably connected. Because the cavity rotating rod is equipped with A through hole 7 communicates with the cavity of the sliding rod, allowing water to enter and clean the sliding rod. Multiple small holes 50 are provided on the rotating rod 45 and the sliding rod 44, and these holes 50 are inclined in one direction. This causes water to flow out from the small holes towards the inclined side of the rod, creating a spiral shape. This not only cleans the sliding rod and rotating rod but also the telescopic fabric 41 next to them. During cleaning, the second screw 43 can be rotated, and the second push-pull ring 47 drives the second push-pull rod 49, causing the sliding rod 44 to slide up and down, thus increasing the area of ​​the telescopic fabric 41 that can be cleaned and ensuring a more thorough cleaning, thereby ensuring the protective component 4 is completely cleaned.

[0036] Furthermore, the protective component in this invention is made entirely of transparent material. The user wears the device on their arm like a sleeve. The transparent material makes it easy for the user to see the operation inside the cavity after wearing it. An LED light bulb is installed on the upper side of the sliding rod with the cavity. The user turns on the light bulb when operating the device for illumination.

[0037] Furthermore, before using the protective device described in this invention, the user opens the wristband 1, passes their hand through the wristband and the protective components on the wristband, and the wristband retracts to fix the protective device to their arm; then, the device is inhaled by opening the three-way valve 22 at the end connected to the first connecting pipe and the end connected to the second connecting pipe, and turning on the suction pump 21 to inhale. The cavity 5 connected to the second connecting pipe will feel a strong suction force. The cavity 5 has good sealing performance, and the thin water pipe hole is connected to the cavity. The thin water pipe hole 6 is connected to the rotating rod 45 with cavity through the transmission pipe 23, which enhances the suction force of the small hole 50 on the rotating rod with cavity. The rotating rod with cavity is connected to the cavity of the sliding rod with cavity, and the suction force of the small hole 50 on the sliding rod with cavity will also be enhanced, collecting the splashed blood and body fluid into the cavity. The transmission pipe draws the blood and body fluid from the cavity into the thin water pipe hole, and transmits it to the cavity through the thin water pipe hole. The liquid is then drawn out of the cavity through the connecting hole connected to the first connecting pipe. To change the protection area, rotating the first screw 42 drives the first push-pull ring 46 to move, which in turn drives the first push-pull rod 48 to move. The first push-pull rod 48 then drives the cavity rotating rod 45 to rotate, changing the flared angle of the protective component and thus altering the protection range. Rotating the second screw 43 drives the second push-pull ring 47 to move, which in turn drives the second push-pull rod 49 to move. A cavity sliding rod is slidably mounted on the cavity rotating rod. The second push-pull rod drives the cavity sliding rod to slide on the cavity rotating rod. During the sliding process, the cavity sliding rod causes the telescopic fabric 41 to extend and retract, further changing the protection range. Changing the flared angle and length allows for diverse changes in the protection range, enabling the size of the protection range to be adjusted arbitrarily according to different situations. After using the protective device, open the three-way valve 22 at the end connected to the third connecting pipe 31 to allow water to pass through the valve. Water enters the cavity from the connecting hole 8 on the outside of the cavity 5, and is injected into the cavity of the rotating rod through the transmission pipe from the thin water pipe hole 6. Since the cavity of the rotating rod and the cavity of the sliding rod are connected by the through hole 7, water will also be injected into the cavity of the sliding rod. Since the small holes on the two rods are inclined in the same direction, the water comes out of the small hole 50 in a spiral shape to clean the protective component. It can clean the cavity sliding rod, the cavity rotating rod, and the telescopic fabric 41. During cleaning, the second screw 43 can be rotated, and the second push-pull ring 47 drives the second push-pull rod 49, thereby driving the cavity sliding rod 44 to slide on the cavity rotating rod, so that the cleaning range of the telescopic fabric 41 is larger and the cleaning is more complete, thus ensuring that the protective component 4 is completely cleaned.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
