Description

Technical Field

[0001] This utility model relates to the field of card reader technology, and in particular to a card swiping device. Background Technology

[0002] A card reader is a common card reading tool, mainly consisting of a base and a recognition sensor. The base has a card slot, and the recognition sensor is installed on the side wall of the card slot. When a card is quickly swiped along the card slot, the card moves relative to the recognition sensor, which can then capture the image information of the card and convert it into a digital signal for further processing by the card reader.

[0003] To improve the accuracy of image information processing, the card reader incorporates a combination of rollers and a code disk. The rollers are mounted on the inner wall of the card slot; as the card passes through the slot, the rollers contact the card surface and rotate. The rollers and code disk are coaxially aligned, and the detection component within the card reader detects the rotation of the code disk to determine the card's movement within the slot. Finally, an algorithm combines the card's image information with its movement to obtain more accurate card information.

[0004] Meanwhile, the radius of the code disk is generally larger than that of the roller to facilitate the detection component in recognizing the rotation of the code disk. Since the roller protrudes from the side wall of the card reader slot and is coaxially arranged with the code disk, a rotation space is provided at the bottom of the base to prevent the code disk from colliding with the card when rotating. This allows the code disk to rotate within the rotation space, and the detection component is correspondingly positioned within this space. In this case, the rotation space is located below the card reader slot. However, in rainy weather or when liquid is spilled, the liquid may seep into the card reader slot and, through the assembly gap between the card reader slot and the outer casing, into the rotation space. This can cause a short circuit in the detection component, preventing it from detecting the code disk's rotation and resulting in inaccurate card information. Utility Model Content

[0005] The main purpose of this invention is to propose a card-swiping device that improves the waterproof performance of the card-swiping device to ensure accurate card information is obtained.

[0006] To achieve the above objectives, this utility model proposes a card-swiping device, characterized in that the card-swiping device comprises:

[0007] The substrate has a cavity and a card slot. The card slot and the cavity are arranged side by side along a first direction, and the card slot and the cavity are separated by a first sidewall. The first sidewall has a rotating hole that connects the card slot and the cavity.

[0008] A contact wheel is rotatably disposed within the cavity and protrudes from the first sidewall through the rotation hole.

[0009] The code disk is rotatably disposed within the cavity and laterally spaced from the contact wheel; the code disk and the contact wheel are connected via a transmission mechanism.

[0010] A detection component is disposed within the cavity and located above the plane of the bottom of the card reader slot. The detection component is used to detect the rotation of the code disk.

[0011] Wherein, the first direction is perpendicular to the depth direction of the card reader slot.

[0012] In one embodiment, the base includes a base plate assembly, a first seat and a second seat, the first seat and the second seat are arranged side by side on the base plate assembly along the first direction, and the first seat, the second seat and the base plate assembly surround to form the card swiping slot, and the first seat and the base plate assembly surround to form the cavity;

[0013] The first seat has a first sidewall facing the second seat, and there is a gap between the detection component and the base plate component.

[0014] In one embodiment, the first seat further includes a support frame disposed within the cavity. The support frame includes a bearing plate connected to the first side wall and two mounting plates. The two mounting plates are disposed opposite to each other. The bearing plate is connected to the two mounting plates respectively and is located at the bottom of the two mounting plates. A gap is provided between the bearing plate and the base plate assembly.

[0015] Both the code disk and the transmission mechanism are located on the support plate, and the rotating hole is located between the two mounting plates.

[0016] In one embodiment, the first base further includes a floating element and an elastic element. The floating element is located between the two mounting plates. The floating element has a floating plate and a movable plate connected to each other. The floating plate is connected to the first side wall through the elastic element and is correspondingly arranged with the rotating hole. The contact wheel is rotatably disposed on the floating plate. The movable plate is slidably disposed on the bearing plate. The transmission mechanism and the code disk are both disposed on the movable plate.

[0017] The contact wheel is pressed by the card and moves along the first direction, and drives the transmission mechanism and the code disk to move along the first direction through the floating member and the elastic member.

[0018] In one embodiment, the first seat further includes two mounting posts disposed in the cavity, the two mounting posts being located on opposite sides of the rotating hole, the floating plate including a first mounting part, a movable part and a second mounting part connected in sequence, the first mounting part and the second mounting part being movably sleeved on the two mounting posts respectively, the elastic member including two, each elastic member having its two sides connected to the first mounting part / second mounting part and the side of the mounting post away from the first sidewall respectively, so as to abut the first mounting part / second mounting part against the first sidewall;

[0019] There is a gap between the movable part and the first sidewall. The movable part has a mounting hole, which is corresponding to the rotating hole. The contact wheel is rotatably disposed on the movable part, and both sides of the contact wheel protrude from the rotating hole and the mounting hole, respectively.

[0020] In one embodiment, the card reader further includes a mounting frame and a second drive shaft. The mounting frame is connected to the floating plate, the code disk is rotatably disposed inside the mounting frame, and the second drive shaft passes through the mounting frame and is connected to the code disk and the transmission mechanism respectively.

[0021] In one embodiment, the detection component includes a first circuit board and a detection sensor. The first circuit board is located between the base plate assembly and the carrier plate, and is spaced apart from the base plate assembly. The detection sensor is disposed on the mounting bracket and electrically connected to the first circuit board for detecting the rotation of the code disk.

[0022] In one embodiment, the transmission mechanism includes:

[0023] A first connecting wheel is rotatably mounted on the floating plate and connected to the contact wheel via a first transmission shaft;

[0024] A second connecting wheel, rotatably mounted on the floating plate and connected to the code disk via a second drive shaft; and

[0025] Multiple transmission wheels are rotatably mounted on the floating plate, and the first connecting wheel, the multiple transmission wheels, and the second connecting wheel mesh with each other in sequence.

[0026] In one embodiment, the radius of the first connecting wheel is not greater than the radius of the second connecting wheel.

[0027] In one embodiment, the second seat has a second sidewall facing the first seat, and the card reader further includes an identification sensor disposed on the second sidewall and corresponding to the contact wheel, for acquiring image information of the card.

[0028] The technical solution of this utility model involves arranging a cavity and a card reader slot side-by-side along a first direction on a substrate, with the cavity and slot separated by a first sidewall. The code disk and detection component are both housed within the cavity. When liquid enters the card reader slot, it flows downwards naturally due to gravity, accumulating at the bottom of the slot and preventing it from entering the cavity. Simultaneously, since the detection component within the cavity is located above the plane of the card reader slot's bottom, even if liquid seeps into the cavity, it will accumulate at the bottom due to gravity, preventing contact with the higher-positioned detection component. This avoids short circuits caused by liquid contact, ensuring stable operation of the card reader and accurate acquisition of card information. Attached Figure Description

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0042] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture.

For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0044] A card reader is a common card reading tool, mainly consisting of a base and a recognition sensor. The base has a card slot, and the recognition sensor is installed on the side wall of the card slot. When a card is quickly swiped along the card slot, the card moves relative to the recognition sensor, which can then capture the image information of the card and convert it into a digital signal for further processing by the card reader.

[0045] To improve the accuracy of image information processing, the card reader incorporates a combination of rollers and a code disk. The rollers are mounted on the inner wall of the card slot; as the card passes through the slot, the rollers contact the card surface and rotate. The rollers and code disk are coaxially aligned, and the detection component within the card reader detects the rotation of the code disk to determine the card's movement within the slot. Finally, an algorithm combines the card's image information with its movement to obtain more accurate card information.

[0046] Meanwhile, the radius of the code disk is generally larger than that of the roller to facilitate the detection component in recognizing the rotation of the code disk. Since the roller protrudes from the side wall of the card reader slot and is coaxially arranged with the code disk, a rotation space is provided at the bottom of the base to prevent the code disk from colliding with the card when rotating. This allows the code disk to rotate within the rotation space, and the detection component is correspondingly positioned within this space. In this case, the rotation space is located below the card reader slot. However, in rainy weather or when liquid is spilled, the liquid may seep into the card reader slot and, through the assembly gap between the card reader slot and the outer casing, into the rotation space. This can cause a short circuit in the detection component, preventing it from detecting the code disk's rotation and resulting in inaccurate card information.

[0047] The main purpose of this utility model is to provide a card swiping device 100, which aims to improve the waterproof performance of the card swiping device 100 in order to ensure accurate card information is obtained.

[0048] Please see Figures 1 to 8 In one embodiment of this utility model, the card-swiping device 100 includes a base 1, a contact wheel 2, a code disk 3, and a detection component 5. The base 1 forms a cavity 122 and a card-swiping slot 17. The card-swiping slot 17 and the cavity 122 are arranged side by side along a first direction, and the card-swiping slot 17 and the cavity 122 are separated by a first sidewall 121. The first sidewall 121 has a rotating hole 1211 that connects the card-swiping slot 17 and the cavity 122. The contact wheel 2 is rotatably disposed in the cavity 122 and partially protrudes from the first sidewall 121 through the rotating hole 1211. The code disk 3 is rotatably disposed in the cavity 122 and is laterally spaced from the contact wheel 2. The code disk 3 and the contact wheel 2 are connected by a transmission mechanism 4. The detection component 5 is disposed in the cavity 122 and is located above the plane where the bottom of the card-swiping slot 17 is located. The detection component 5 is used to detect the rotation of the code disk 3. The first direction is perpendicular to the depth direction of the card-swiping slot 17.

[0049] Understandably, by arranging a cavity 122 and a card reader 17 side-by-side along a first direction on the substrate 1, with the cavity 122 and card reader 17 separated by a first sidewall 121, and the code disk 3 and detection component 5 both disposed within the cavity 122, when liquid enters the card reader 17, it will naturally flow downwards due to gravity and accumulate at the bottom of the card reader 17, without entering the cavity 122. Simultaneously, since the detection component 5 within the cavity 122 is located above the plane where the bottom of the card reader 17 is located, even if liquid from the bottom of the card reader seeps into the cavity 122, it will accumulate at the bottom of the cavity 122 due to gravity, preventing contact with the higher-positioned detection component 5. This avoids short-circuit problems caused by liquid contact, ensuring the stable operation of the card reader 100 and the accurate acquisition of card information.

[0050] In one implementation, please refer to Figure 1 , Figure 2 and Figure 3 The base 1 includes a base plate assembly 11, a first seat 12 and a second seat 13. The first seat 12 and the second seat 13 are arranged side by side on the base plate assembly 11 along a first direction, and the first seat 12, the second seat 13 and the base plate assembly 11 enclose a card swiping slot 17. The first seat 12 and the base plate assembly 11 enclose a cavity 122. The first seat 12 has a first sidewall 121 facing the second seat 13. There is a gap between the detection component 5 and the base plate assembly 11.

[0051] In this embodiment, the first seat 12 includes a first outer shell, and a first sidewall 121 is provided on the side of the first outer shell facing the second seat 13. The first outer shell, the first sidewall 121, and the base plate assembly 11 enclose a cavity 122, in which the code disk 3 and the detection assembly 5 are both disposed. The second seat 13 includes a second outer shell, which is arranged side by side with the first outer shell along a first direction. A second sidewall 131 is provided on the side of the second outer shell facing the first seat 12. Other electronic components, such as an identification sensor 132, are placed inside the second outer shell. A card swiping slot 17 is formed by the cooperation between the first sidewall 121, the second sidewall 131, and the base plate assembly 11.

[0052] Alternatively, for ease of installation, the first and second housings can be integrally molded.

[0053] Optionally, the base plate assembly 11 may include a first plate and a second plate, which are spaced apart along the depth direction of the card reader slot 17. A first seat 12 and a second seat 13 are mounted on the second plate. Understandably, because there is a gap between the first and second plates, the height of the first seat 12 and the second seat 13 can be raised, so even if the bottom of the card reader 100 is in liquid, the liquid is less likely to seep into the cavity 122, thus preventing a short circuit.

[0054] Optionally, foot pads may also be provided on the bottom of the base plate assembly 11 to improve stability.

[0055] In one implementation, please refer to Figure 5 The first base 12 also includes a support frame 14, which is disposed in the cavity 122. The support frame 14 includes a bearing plate 141 connected to the first side wall 121 and two mounting plates 142. The two mounting plates 142 are arranged opposite to each other. The bearing plate 141 is connected to the two mounting plates 142 respectively and is located at the bottom of the two mounting plates 142. There is a gap between the bearing plate 141 and the base plate assembly 11. The encoder 3 and the transmission mechanism 4 are both disposed on the bearing plate 141, and the rotating hole 1211 is located between the two mounting plates 142.

[0056] In this embodiment, the support frame 14 is installed inside the cavity 122 to support the code disk 3 and the transmission mechanism 4. The support frame 14 includes a support plate 141 and two mounting plates 142. The support plate 141 and the two mounting plates 142 are both connected to the first side wall 121. The support plate 141 is located at the bottom of the two mounting plates 142, and there is a gap between the support plate 141 and the base plate assembly 11. The code disk 3 and the transmission mechanism 4 are mounted on the support plate 141.

[0057] Understandably, at this time, the first side wall 121 and the support frame 14 enclose an installation space to facilitate the rotation of the encoder 3 and the transmission mechanism 4 within the installation space, thereby avoiding interference with other electronic components in the cavity 122.

[0058] In one implementation, please refer to Figure 5 and Figure 6 The first base 12 also includes a floating element 15 and an elastic element 16. The floating element 15 is located between two mounting plates 142 and has a floating plate 151 and a movable plate 152 connected to each other. The floating plate 151 is connected to the first side wall 121 through the elastic element 16 and is correspondingly arranged with the rotating hole 1211. The contact wheel 2 is rotatably mounted on the floating plate 151. The movable plate 152 is slidably mounted on the bearing plate 141. The transmission mechanism 4 and the code disk 3 are both mounted on the movable plate 152. The contact wheel 2 is pressed by the card and moves along the first direction, driving the transmission mechanism 4 and the code disk 3 to move along the first direction through the floating element 15 and the elastic element 16.

[0059] In this embodiment, the floating element 15 is located between two mounting plates 142 and includes a floating plate 151 and a movable plate 152. The floating plate 151 is connected to the first sidewall 121 via an elastic element 16 and is correspondingly arranged with the rotating hole 1211. The contact wheel 2 is mounted on the floating plate 151. The movable plate 152 is slidably mounted on the support plate 141, and the transmission mechanism 4 and the code disk 3 are both mounted on the movable plate 152. When the card passes through the card reader slot 17, it will squeeze the contact wheel 2, causing the contact wheel 2 to move in the first direction. The floating element 15 drives the transmission mechanism 4 and the code disk 3 to move in the first direction. At the same time, the elastic element 16 undergoes elastic deformation, generating elastic force to ensure that the contact wheel 2 is in close contact with the card. This allows the contact wheel 2 to automatically adjust its position when the card passes through, thereby better adapting to changes in card thickness and improving the adaptability of the card reader 100.

[0060] Optionally, the elastic element 16 can be a spring, rubber or other elastic material, or a spring sheet structure.

[0061] In one implementation, please refer to Figure 6 and Figure 7The first seat 12 also includes two mounting posts 123 disposed in the cavity 122. The two mounting posts 123 are respectively located on opposite sides of the rotating hole 1211. The floating plate 151 includes a first mounting part 1511, a movable part 1513, and a second mounting part 1512 connected in sequence. The first mounting part 1511 and the second mounting part 1512 are respectively movably sleeved on the two mounting posts 123. The elastic element 16 includes two parts, and the two sides of each elastic element 16 are respectively connected to the first mounting part 1511 / the second mounting part 1512. The mounting part 1512 and the mounting post 123 are connected to the side away from the first sidewall 121 so that the first mounting part 1511 / second mounting part 1512 abuts against the first sidewall 121; the movable part 1513 is provided with a gap between it and the first sidewall 121, and the movable part 1513 is provided with a mounting hole 1514, which is correspondingly provided with the rotating hole 1211. The contact wheel 2 is rotatably provided on the movable part 1513, and the two sides of the contact wheel 2 protrude from the rotating hole 1211 and the mounting hole 1514 respectively.

[0062] In this embodiment, two mounting posts 123 are also provided on the first sidewall 121, and the two mounting posts 123 are respectively located on opposite sides of the rotating hole 1211. The floating plate 151 is formed by sequentially connecting the first mounting part 1511, the movable part 1513, and the second mounting part 1512, and the first mounting part 1511 and the second mounting part 1512 are respectively movably sleeved on the two mounting posts 123. The elastic element 16 is two springs. The first mounting part 1511 and the second mounting part 1512 are installed in the same way. Taking the first mounting part 1511 as an example, the two sides of the spring are respectively connected to the side of the first mounting part 1511 and the mounting post 123 away from the first sidewall 121, so that the first mounting part 1511 abuts against the first sidewall 121. There is a gap between the movable part 1513 and the first sidewall 121. The mounting hole 1514 on the movable part 1513 is correspondingly provided with the rotating hole 1211. The mounting hole 1514 can facilitate the installation of the contact wheel 2 on the movable part 1513.

[0063] Understandably, the floating plate 151 can slide along the mounting post 123 under the action of the elastic element 16, thereby realizing the position adjustment of the contact wheel 2 and further improving the stability of the card reader 100 when swiping the card.

[0064] Alternatively, a bolt can be inserted on the side of the mounting post 123 away from the first sidewall 121 so that the elastic element 16 abuts against the nut.

[0065] Alternatively, the mounting post 123 can be omitted. In this case, the elastic element 16 is directly connected to the first side wall 121 and the floating plate 151, which also allows the floating element 15 to move along the first direction. Meanwhile, to ensure stability, a guide structure, such as a guide rail or a groove, can be provided between the movable plate 152 and the supporting plate 141 to ensure that the movable plate 152 can slide smoothly and enhance stability during card swiping.

[0066] In one implementation, please refer to Figure 3 and Figure 8 The card reader 100 also includes a mounting frame 31 and a second drive shaft 32. The mounting frame 31 is connected to the floating plate 151. The code disk 3 is rotatably disposed inside the mounting frame 31. The second drive shaft 32 passes through the mounting frame 31 and is connected to the code disk 3 and the transmission mechanism 4 respectively.

[0067] In this embodiment, the card reader 100 is further provided with a mounting frame 31 and a second drive shaft 32. The mounting frame 31 is detachably connected to the floating plate 151. The code disk 3 is rotatably mounted inside the mounting frame 31. The second drive shaft 32 passes through the mounting frame 31 and is connected to the code disk 3 and the transmission mechanism 4 respectively. It can be understood that the code disk 3 can achieve power transmission through the second drive shaft 32 and the transmission mechanism 4, thereby realizing the rotation of the code disk 3. The mounting frame 31 facilitates the installation of the code disk 3, making it easier for the code disk 3 to move with the floating member 15.

[0068] Optionally, the mounting bracket 31 and the movable plate 152 can be connected by various methods such as threaded connection or snap-fit ​​connection. To ensure stability during installation, multiple mounting structures can be symmetrically arranged for installation.

[0069] In one implementation, please refer to Figure 4 and Figure 5 The detection component 5 includes a first circuit board 51 and a detection sensor 52. The first circuit board 51 is located between the base plate assembly 11 and the support plate 141, and is spaced apart from the base plate assembly 11. The detection sensor 52 is mounted on the mounting bracket 31 and is electrically connected to the first circuit board 51 for detecting the rotation of the code disk 3.

[0070] In this embodiment, the first circuit board 51 is installed between the base plate assembly 11 and the support plate 141, with a gap between them to avoid the influence of vibration or heat from the base plate assembly 11 on the first circuit board 51. The detection sensor 52 is installed on the mounting bracket 31 and electrically connected to the first circuit board 51 for detecting the rotation of the code disk 3.

[0071] Optionally, the detection sensor 52 can be of various types, such as photoelectric sensors and Hall sensors.

[0072] In one implementation, please refer to Figure 4 and Figure 5The card reader 100 also includes a second circuit board 124, which is disposed on and electrically connected to the first circuit board 51. The code disk 3, the detection sensor 52, and the contact wheel 2 are all located between the second circuit board 124 and the first circuit board 51. The second circuit board 124 is located at the top of the cavity 122 and is connected to the induction coil, enabling contactless card reading on the upper surface of the device.

[0073] In this embodiment, the second circuit board 124 is mounted on and electrically connected to the first circuit board 51. The code disk 3, the detection sensor 52, and the contact wheel 2 are all located between the second circuit board 124 and the first circuit board 51. The second circuit board 124 is located at the top of the cavity 122 and is connected to the induction coil, enabling contactless card reading on the upper surface of the first seat 12. This allows the card reader 100 to not only read card information through the card slot 17 but also perform contactless card reading through the induction coil, thereby improving the functionality of the card reader 100.

[0074] In one implementation, please refer to Figure 1 and Figure 2 The top of the base 1 is provided with a first slot 18, which is connected to the cavity 122. The card reader 100 also includes a third circuit board 125. When a card is inserted into the first slot 18, the card reader on the third circuit board 125 can read the card to achieve contact card reading.

[0075] Optionally, a second slot can be provided at the bottom of the base 1. The second slot is smaller than the first slot 18 and can be used to insert smaller cards, such as SIM cards, for reading and identification. Understandably, by providing the first slot 18 and the second slot, the functionality of the card reader 100 can be further increased.

[0076] Optionally, a dustproof and waterproof structure, such as a sealing strip or a waterproof membrane, can be provided inside the first slot 18 to improve the protective performance of the first slot 18.

[0077] In one implementation, please refer to Figure 8 The transmission mechanism 4 includes a first connecting wheel 41, a second connecting wheel 42, and multiple transmission wheels 43. The first connecting wheel 41 is rotatably mounted on the floating plate 151 and is connected to the contact wheel 2 via a first transmission shaft 21. The second connecting wheel 42 is rotatably mounted on the floating plate 151 and is connected to the encoder 3 via a second transmission shaft 32. The multiple transmission wheels 43 are all rotatably mounted on the floating plate 151, and the first connecting wheel 41, the multiple transmission wheels 43, and the second connecting wheel 42 mesh sequentially.

[0078] In this embodiment, the code disk 3 and the contact wheel 2 are driven by gears, and two transmission wheels 43 are provided. The gear transmission method can ensure the reliability of the transmission process, thereby improving the detection accuracy. At the same time, using two transmission wheels 43 for transmission can ensure that there is a sufficient distance between the code disk 3 and the contact wheel 2, while also avoiding excessive energy loss.

[0079] Alternatively, the code disk 3 and the contact wheel 2 can also be driven by a belt. It should be noted that in this case, the code disk 3 and the contact wheel 2 must be installed more stably on the floating part 15 to prevent them from sliding relative to the floating part 15 during movement, which would prevent the belt from maintaining tension and affect the detection accuracy.

[0080] In one implementation, please refer to Figure 8 The radius of the first connecting wheel 41 is not greater than the radius of the second connecting wheel 42.

[0081] Understandably, because the first connecting wheel 41 has a smaller radius, it can rotate rapidly within a smaller space, while the second connecting wheel 42 has a larger radius, which can better withstand larger torque, thus achieving more stable power transmission and ensuring the detection accuracy of the detection sensor 52. At the same time, in order to avoid the rotation of the first connecting wheel 41 affecting the card, the radius of the first connecting wheel 41 must be smaller than the radius of the contact wheel 2.

[0082] Optionally, the first connecting wheel 41, the plurality of transmission wheels 43, and the second connecting wheel 42 may also be of the same size to facilitate installation.

[0083] In one implementation, please refer to Figure 2 and Figure 4 The second seat 13 has a second sidewall 131 facing the first seat 12. The card reader 100 also includes an identification sensor 132, which is located on the second sidewall 131 and is correspondingly set with the contact wheel 2 to acquire image information of the card.

[0084] Understandably, the contact wheel 2 provides a resisting force through the elastic element 16, pushing the card towards the second sidewall 131 where the recognition sensor 132 is located. As the card slides along the card reader 17, the elastic force of the contact wheel 2 continuously adjusts the position of the card, ensuring that it always adheres to the second sidewall 131, thereby ensuring that the distance between the card and the recognition sensor 132 remains constant, and ensuring that the recognition sensor 132 can stably acquire the image information of the card.

[0085] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
