Description

Technical Field

[0001] The present invention relates to the technical field of intelligent screen mirroring digital photo frames, and specifically provides an intelligent screen mirroring digital photo frame. Background Technique

[0002] With the continuous development of technology, digital photo frames, as a kind of household electronic products that can display multimedia content such as electronic pictures and videos, have gradually entered people's daily lives. Traditional digital photo frames usually have a storage function. Users can store photos, videos and other files in the built-in memory of the photo frame or import them into the photo frame through external storage devices (such as SD cards, USB flash drives, etc.), and then browse and display them on the display screen of the photo frame. In recent years, with the popularization of mobile devices such as smart phones and tablets, people's demand for sharing and displaying multimedia content anytime and anywhere has increased day by day. For example, users can display the content of wonderful moments such as photos and videos taken on their mobile phones on the photo frame screen in real time and watch them with family and friends to enhance the emotional communication among family members. They can also screen mirror movies, TV series, etc. on the mobile phone to the photo frame and use it as a simple display terminal for a home theater to enrich family entertainment life.

[0003] The existing Chinese patent with the publication number CN219435524U includes a support base. The front part of the upper end of the support base is fixedly connected with a playing mechanism. A fixing mechanism is fixedly connected between the left part and the right part of the upper end of the playing mechanism. An adjusting groove is opened at the rear part of the upper end of the support base. Limiting grooves are opened in the middle of the left groove wall and the middle of the right groove wall of the adjusting groove. An adjusting mechanism is movably connected between the front groove wall and the rear groove wall of the adjusting groove. The upper end of the adjusting mechanism and the upper end of the fixing mechanism are fixedly connected with a photo frame body together. A touch display screen is embedded in the middle of the front end of the photo frame body.

[0004] When the above device is in use, by setting the fixing mechanism and the adjusting mechanism, turning the adjusting screw rod drives the adjusting block to move, so that the support rod can support or pull down the digital photo frame, and the placement angle of the digital photo frame can be adjusted. However, in the actual use process, when a person is on the side of the digital photo frame, the content of the digital photo frame cannot be observed, and the person needs to manually rotate the digital photo frame or move to the front of the digital photo frame by himself to watch. The function is relatively single, which reduces the flexibility of the digital photo frame. Therefore, it is difficult to automatically adjust the digital photo frame to rotate in all directions.

[0005] Therefore, we propose an intelligent screen mirroring digital photo frame. Summary of the Invention

[0013] On both sides of the annular plate near the symmetric positions of the fixed plate, there are fixedly connected stoppers for unlocking the threaded sleeve, and the two stoppers are in corresponding positions with the moving plate.

[0014] Preferably, on both sides of each digital photo frame body, there are fixedly connected slide rails. On the slide rails on both sides of each digital photo frame body, there is movably connected an inverted U-shaped frame for reciprocating movement. On the opposite surfaces of both ends of each inverted U-shaped frame, there is a cleaning roller for cleaning the digital photo frame body that is penetrated and rotatably connected to a fixed axis. An auxiliary mechanism for driving the cleaning roller to move and clean the surface of the digital photo frame body is provided on the rectangular frame;

[0015] The auxiliary mechanism includes two rotating rods that are rotatably connected to the symmetric positions on both sides near the bottom end of the two rectangular frames for reciprocating rotation towards or away from each other. On the symmetric positions on both sides of the two inverted U-shaped frames, there are fixedly connected support blocks. On each rotating rod, there is a support groove for movably supporting the support block.

[0016] Preferably, on the opposite surfaces of the two rotating rods on the same side, there are provided limiting grooves.

[0021] The control module automatically adjusts the display angle and content layout of the digital photo frame body according to the information detected by the sensor module.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] First, the threaded rod drives the T-shaped blocks to face each other, and the connecting seat rotatably supports the digital photo frame body. At this time, the end of the digital photo frame body away from the connecting seat pushes the rectangular plate to move in the upward vertical direction under the action of the T-shaped block, and the end of the digital photo frame body away from the connecting seat synchronously moves in the upward direction, realizing precise adjustment of the display angle of the digital photo frame body, being able to better display detailed content, and also being able to achieve the best display effect through angle adjustment, enhancing the practicability and adaptability of the digital photo frame.

[0024] Second, through the rotational connection of the annular plate on the inner wall of the annular groove, and the first disk can drive the first transmission block and the second transmission block to engage and transmit under the action of the threaded sleeve. Thus, the annular plate can drive the digital photo frame body to rotate in all directions under the action of the first transmission block and the second transmission block, realizing the all-round rotation adjustment of the digital photo frame body. No matter which side of the digital photo frame a person is on, they can easily view the content on the photo frame without manually rotating the photo frame or moving to the front to view, greatly improving the convenience and flexibility of viewing, especially suitable for scenarios such as family gatherings and business exhibitions where multiple people watch, enabling everyone to obtain a good viewing experience.

[0025] Third, as the rectangular plate drives the slider to move up and down reciprocally, the T-shaped rod can pull the two side rotating rods to rotate towards or away from each other reciprocally. Thus, the support block can drive the cleaning roller to move reciprocally on the surface of the digital photo frame body under the pull of the rotating rod, and the gears at both ends of the cleaning roller mesh with the toothed plate to drive the cleaning roller to rotate for cleaning under the drive of the inverted U-shaped frame. Thus, the cleaning roller can erase and clean stains such as dust and fingerprints on the screen surface, eliminating the need for users to manually wipe the screen, always maintaining the cleanliness of the screen of the digital photo frame body, thereby ensuring the clarity and visual effect of the displayed content, enabling users to more clearly appreciate the details of multimedia content such as pictures and videos, and enhancing the viewing experience.

[0026] 4. By rotating the rods in opposite directions, the inverted U-shaped frame is driven to move, causing the U-shaped frame to pull the cover cloth to cover the digital photo frame body, achieving effective protection for the digital photo frame body. The cover cloth can prevent direct contact and contamination of the screen by dust, debris, etc., protecting the screen from scratches and damage. Especially in some places with more dust or a more complex environment, it can effectively extend the service life of the digital photo frame and reduce maintenance costs.

[0027] By using the cooperation of the above structure, the problem that in the actual use process of the existing device, when a person is on the side of the digital photo frame, the content of the digital photo frame cannot be observed, and the person needs to manually rotate the digital photo frame or move to the front of the digital photo frame by himself to watch, the function is relatively single, reducing the flexibility of the digital photo frame, and thus it is difficult to automatically adjust the digital photo frame to rotate in all directions is solved.

[0047] In use, through the cylindrical rods 7 provided on the fixing plate 6, the cylindrical rods 7 are fixedly supported on the fixing plate 6. Through the T-shaped blocks 8 provided on the cylindrical rods 7, and the cylindrical rods 7 support the T-shaped blocks 8, enabling the T-shaped blocks 8 to horizontally reciprocally move and be connected on the cylindrical rods 7. Through the connecting seats 9 provided on the T-shaped blocks 8, the connecting seats 9 can rotatably support the bottom end of the digital photo frame body 5, ensuring the stability of the digital photo frame body 5.

[0048] Embodiment Two:

[0049] On the basis of Embodiment One, further:

[0050] The adjusting mechanism includes two fixing plates 6 which are both penetrated and rotatably connected with a threaded rod 11 that drives the T-shaped block 8 to move towards or away from each other. The threaded rod 11 is driven to rotate by a power mechanism. Both of the T-shaped blocks 8 are penetrated and rotatably connected with a threaded sleeve 10, and the threaded sleeves 10 are sleeved on the outer contour of the threaded rod 11 and are screwed. The T-shaped block 8 is provided with a locking mechanism for fixing the threaded sleeve 10.

[0051] During use, through the threaded rod 11 arranged on the fixing plate 6, and the threaded rod 11 is driven to rotate by a motor, the motor can drive the threaded rod 11 to perform a fixed-axis reciprocating rotation on the fixing plate 6. Through the threaded sleeve 10 arranged on the T-shaped block 8, the threaded sleeve 10 is rotatably connected to the inner wall of the T-shaped block 8. At the same time, the threaded sleeve 10 is sleeved on the outer contour of the threaded rod 11 and is screwed. And the locking mechanism arranged on the T-shaped block 8 can lock the threaded sleeve 10 by the locking mechanism. Along with the fixed-axis reciprocating rotation of the threaded rod 11, the threaded sleeve 10 can drive the two T-shaped blocks 8 on both sides to move towards or away from each other reciprocally under the action of the threaded rod 11.

[0052] The locking mechanism includes moving grooves 801 which are respectively opened at the corresponding positions of the two T-shaped blocks 8. The inner walls of the two moving grooves 801 are respectively connected with locking blocks 12 for locking the threaded sleeve 10 in a lifting and moving manner. Locking grooves 111 which are adapted to the locking blocks 12 are respectively opened on the outer contours of each threaded sleeve 10 at the corresponding positions of the locking blocks 12.

[0053] One side of each T-shaped block 8 close to the locking block 12 is penetrated and horizontally connected with a moving plate 14. One side of each locking block 12 close to the moving plate 14 is fixedly connected with a movable block 13. Oblique grooves 141 for supporting the movable block 13 are respectively opened on each moving plate 14. Circular plates 15 are respectively fixedly connected to the opposite ends of the two moving plates 14. Springs 16 for guiding the reset movement of the moving plate 14 are respectively fixedly connected between each circular plate 15 and the opposite surface of the adjacent T-shaped block 8.

[0054] In use, through the movable slot 801 formed on the T-shaped block 8 and the locking block 12 provided on the movable slot 801, the movable slot 801 supports the moving direction of the locking block 12. And for the locking slot 111 formed on the threaded sleeve 10, the locking slot 111 is adapted to the outer contour of the locking block 12. Through the moving plate 14 provided on the T-shaped block 8, the moving plate 14 can be horizontally movably connected to the T-shaped block 8. Through the inclined slot 141 formed on the moving plate 14 and the movable block 13 provided on the locking block 12, the movable block 13 can support the position of the locking block 12 under the action of the inclined slot 141. Through the circular plate 15 provided on the moving plate 14 and the spring 16 provided on the circular plate 15, the circular plate 15 can support the position of the moving plate 14 under the action of the spring 16.

[0055] As Figure 1 , Figure 2 and Figure 7 shown, the initial positions of the two T-shaped blocks 8 are respectively close to the extreme positions of the adjacent fixing plates 6 on one side, and the slider 301 drives the rectangular plate 4 to move to the extreme position at the bottom of the rectangular frame 3, so that the digital photo frame body 5 and the rectangular plate 4 are in the same horizontal state. And the spring 16 pushes the circular plate 15 to move in the reset direction away from the T-shaped block 8, then the end of the inclined slot 141 close to the threaded sleeve 10 moves to the corresponding position of the movable block 13, which can make the movable block 13 push the locking block 12 to move to the inner wall of the locking slot 111. At this time, the locking block 12 locks the threaded sleeve 10. Along with the fixed-axis reciprocating rotation of the threaded rod 11, the threaded sleeve 10 can drive the two T-shaped blocks 8 to move reciprocally towards or away from each other under the action of the threaded rod 11.

[0056] When it is necessary to adjust the display angle of the digital photo frame body 5, when the threaded rod 11 rotates clockwise, the threaded sleeve 10 drives the T-shaped block 8 to move towards each other. And the connecting seat 9 rotatably supports the digital photo frame body 5. At this time, the end of the digital photo frame body 5 away from the connecting seat 9 pushes the rectangular plate 4 to move in the upward vertical direction under the action of the T-shaped block 8, and the end of the digital photo frame body 5 away from the connecting seat 9 synchronously moves in the upward direction, realizing the adjustment of the display angle of the digital photo frame body 5.

[0057] When the threaded rod 11 rotates counterclockwise and the threaded sleeve 10 drives the T-shaped block 8 to move in the reset direction away from each other, the above structure can move in the opposite direction synchronously for reset.

[0058] Embodiment Three:

[0059] On the basis of Embodiment Two, furthermore:

[0060] The transmission mechanism includes a second disc 20 fixedly connected to the central position of the base 1. A plurality of uniformly arranged second transmission blocks 21 are annularly arrayed near the edge of the second disc 20. One end of the threaded sleeve 10 near the second disc 20 is fixedly connected to a first disc 18. A plurality of uniformly arranged first transmission blocks 19 are annularly arrayed near the edge of the first disc 18. The first transmission blocks 19 and the second transmission blocks 21 are staggeredly arranged and in transmission connection.

[0061] On both sides of the annular plate 2 symmetrically near the fixed plate 6, there are fixedly connected stoppers 17 for unlocking the threaded sleeve 10. The two stoppers 17 are in corresponding positions with the moving plate 14.

[0062] During use, through the stopper 17 provided on the annular plate 2, the stopper 17 is fixedly supported on the annular plate 2, and the stopper 17 is in corresponding position with the circular plate 15. When the threaded rod 11 rotates clockwise and drives the T-shaped block 8 to move towards each other to the limit position, the T-shaped block 8 can drive the circular plate 15 to abut against the stopper 17 and move. At this time, the T-shaped block 8 moves towards the direction close to the circular plate 15, then the spring 16 is squeezed and contracted under the action of the T-shaped block 8, and the locking block 12 can drive the movable block 13 to move towards the end of the inclined slot 141 away from the threaded sleeve 10 under the action of the T-shaped block 8. Thus, the movable block 13 can pull the locking block 12 to move in the vertical direction away from the connecting seat 9 under the action of the inclined slot 141, and the locking block 12 is disengaged from the locking slot 111 and the locking state of the threaded sleeve 10 is released, so that the threaded rod 11 can drive the threaded sleeve 10 to rotate synchronously inside the T-shaped block 8.

[0063] Such as Figure 1 、 Figure 9 、 Figure 10 and Figure 11As shown, the second disc 20 is fixedly supported on the base 1 by the second disc 20 provided on the base 1, and the second transmission block 21 provided on the second disc 20 makes the second transmission block 21 fixedly supported on the second disc 20, and the first disc 18 is fixedly supported on the threaded sleeve 10 by the first disc 18 provided on the threaded sleeve 10, and the first transmission block 19 is fixedly supported on the first disc 18 by the first transmission block 19 provided on the first disc 18, and when the T-shaped blocks 8 move toward each other to the extreme position, the first disc 18 can drive the second transmission block 21 to be fixedly supported on the second disc 20. A transmission block 19 moves and is interlacedly connected with the second transmission block 21 on the second disc 20, and the threaded rod 11 drives the threaded sleeve 10 to rotate synchronously, and the first disc 18 can drive the first transmission block 19 and the second transmission block 21 to engage and transmit under the action of the threaded sleeve 10, so that the annular plate 2 can drive the digital photo frame body 5 to rotate in all directions under the action of the first transmission block 19 and the second transmission block 21, thereby improving the flexibility of the digital photo frame body 5, so that people can view the content displayed on the digital photo frame body 5 at any position.

[0064] As the threaded rod 11 rotates counterclockwise, the T-shaped block 8 can be reset and moved in the direction away from the circular plate 15 under the elastic force of the spring 16, and the movable block 13 can push the locking block 12 to reset and move to the inner wall of the locking groove 111 under the action of the inclined groove 141, so that the locking block 12 locks the threaded sleeve 10, and then the threaded rod 11 can drive the T-shaped block 8 to reset and move in the opposite direction synchronously.

[0065] Embodiment 4:

[0066] On the basis of the third embodiment, further:

[0067] Each of the digital photo frame bodies 5 is fixedly connected to a slide rail 22 at a symmetrical position on both sides, and an inverted U-shaped frame 23 for reciprocating movement is movably connected to the slide rails 22 on both sides of each of the digital photo frame bodies 5. The opposite surfaces at both ends of each inverted U-shaped frame 23 are penetrated and connected to a cleaning roller 24 for cleaning the digital photo frame body 5 for fixed axis rotation. The rectangular frame 3 is provided with an auxiliary mechanism for driving the cleaning roller 24 to move and clean the surface of the digital photo frame body 5.

[0068] During use, through the slide rail 22 provided on the digital photo frame body 5, the slide rail 22 is fixedly supported on the digital photo frame body 5, and the inverted U-shaped frame 23 provided on the slide rail 22 enables the slide rail 22 to support the moving direction of the inverted U-shaped frame 23. Through the inverted U-shaped frame 23 provided on the slide rail 22, the inverted U-shaped frame 23 is rotatably supported on the slide rail 22, and the outer contour of the inverted U-shaped frame 23 is in contact with the surface of the digital photo frame body 5. Along with the auxiliary mechanism provided on the rectangular frame 3, the auxiliary mechanism can drive the inverted U-shaped frame 23 to move to clean the dust and fingerprints on the surface of the digital photo frame body 5, ensuring the cleanliness of the surface of the digital photo frame body 5, improving the display effect of the digital photo frame body 5, and avoiding the problem that the surface of the digital photo frame body 5 is attached with dust due to long-term exposure to the outside and fingerprints left during personnel touch operation, which affects the display effect of the digital photo frame body 5.

[0069] The auxiliary mechanism includes rotating rods 26 that are rotatably connected by fixed axes at symmetric positions on both sides near the bottom end of the two rectangular frames 3 and perform reciprocating rotation towards or away from each other. Support blocks 25 are fixedly connected to symmetric positions on both sides of the two inverted U-shaped frames 23. Support grooves 261 for movably supporting the support blocks 25 are provided on each of the rotating rods 26.

[0070] Limit grooves 262 are provided on the opposite surfaces of the two rotating rods 26 on the same side. A sliding seat 27 is movably connected to the inner wall of each limit groove 262. T-shaped rods 28 for driving the rotating rods 26 to perform reciprocating rotation towards or away from each other are fixedly connected to the opposite surfaces of the two sliding blocks 301. The two ends of each T-shaped rod 28 are respectively rotatably connected to the adjacent sliding seat 27 at one end.

[0071] During use, through the rotating rods 26 provided on the rectangular frame 3, the rotating rods 26 are rotatably supported on the rectangular frame 3. Through the support grooves 261 provided on the rotating rods 26 and the support blocks 25 provided on the inverted U-shaped frame 23, the support blocks 25 can support the position of the inverted U-shaped frame 23 under the action of the support grooves 261. Through the limit grooves 262 provided on the rotating rods 26 and the sliding seats 27 provided on the limit grooves 262, the limit grooves 262 can movably support the moving direction of the sliding seats 27. And the T-shaped rods 28 provided on the sliding blocks 301 are fixedly supported on the sliding blocks 301, and the two ends of the T-shaped rods 28 are respectively rotatably supported by the adjacent sliding seats 27 on one side, enabling the T-shaped rods 28 to support the rotation angle of the rotating rods 26 under the action of the sliding seats 27.

[0072] Such as Figure 1 、 Figure 2 、 Figure 4 and Figure 8As shown in the figure, when the rectangular plate 4 drives the slider 301 to move in the downward vertical direction for reset, and the slider 301 drives the T-shaped rod 28 to move synchronously, the T-shaped rod 28 can push the rotating rods 26 on both sides to rotate in the opposite directions, and the support block 25 can pull the inverted U-shaped frame 23 to move towards the end close to the connecting seat 9 under the action of the support groove 261. Thus, the cleaning roller 24 can move along with the inverted U-shaped frame 23 to wipe and clean the dust and fingerprints on the surface of the digital photo frame body 5. When the rectangular plate 4 drives the slider 301 to move in the upward vertical direction for reset, the above structure moves in the opposite direction synchronously for reset, realizing that the inverted U-shaped frame 23 can drive the cleaning roller 24 to reciprocally clean the surface of the digital photo frame body 5, ensuring the cleanliness of the surface of the digital photo frame body 5 and improving the display effect of the digital photo frame body 5.

[0073] On both sides of the digital photo frame body 5 near the two sides of the slide rail 22 at symmetrical positions, there are fixedly connected with toothed plates 29 that drive the cleaning roller 24 to rotate and clean. At the corresponding positions of both ends of each cleaning roller 24 and the toothed plate 29, there are coaxially fixedly connected with gears 30, and the gears 30 mesh with the teeth on the toothed plate 29.

[0074] During use, through the toothed plate 29 arranged on the digital photo frame body 5, the toothed plate 29 is fixedly supported on the digital photo frame body 5. Through the gear 30 arranged on the cleaning roller 24, the gear 30 is coaxially fixedly connected with the cleaning roller 24, and the gear 30 meshes with the teeth on the toothed plate 29 for meshing transmission. Along with the inverted U-shaped frame 23 driving the cleaning roller 24 to reciprocally move on the digital photo frame body 5, the gear 30 can drive the cleaning roller 24 to rotate and clean the surface of the digital photo frame body 5 under the action of the toothed plate 29, further improving the cleaning effect of the cleaning roller 24.

[0075] Embodiment Five:

[0076] On the basis of Embodiment Four, furthermore:

[0077] At the symmetrical positions at both ends of the two rectangular plates 4 on both sides, there are fixedly connected with fixing blocks 31. On the opposite surfaces of each two fixing blocks 31 on each side, there is a through hole and a rotatable connection with a winding roller 32. On the outer contours of the two winding rollers 32 on both sides, there are rolled and stored cover cloths 33 that avoid blocking the digital photo frame body 5. One end of each cover cloth 33 away from the winding roller 32 is fixedly connected with the inverted U-shaped frame 23 on the adjacent side respectively. At the opposite surfaces of both ends of each winding roller 32 and the fixing block 31, there are fixedly connected with torsion springs 34 that guide the winding roller 32 to rotate for reset.

[0078] In use, through the fixing block 31 provided on the rectangular plate 4, the fixing block 31 is fixedly supported on the rectangular plate 4, and the winding roller 32 provided on the fixing block 31 is rotatably supported on the fixing block 31. Through the covering cloth 33 provided on the winding roller 32, the covering cloth 33 is rolled and stored on the winding roller 32, and the torsion spring 34 provided on the winding roller 32 can support the position of the winding roller 32 by the torsion spring 34.

[0079] As Figure 1 - Figure 3 shown, when the digital photo frame body 5 is not in use, as the rotating rod 26 rotates away from each other and drives the inverted U-shaped frame 23 to move towards one end close to the connecting seat 9, and one end of the covering cloth 33 away from the winding roller 32 is fixedly supported on the inverted U-shaped frame 23, the inverted U-shaped frame 23 can pull the covering cloth 33 to cover the digital photo frame body 5, realizing that the covering cloth 33 can protect the surface of the digital photo frame body 5 from being blocked, and the winding roller 32 rotates under the pulling of the inverted U-shaped frame 23 to release the covering cloth 33, so that the torsion spring 34 is in a contracted state under the action of the winding roller 32.

[0080] When the digital photo frame body 5 is in use, as the rotating rod 26 rotates in the opposite direction and drives the inverted U-shaped frame 23 to move away from the connecting seat 9, at this time, the inverted U-shaped frame 23 releases the pulling force on the covering cloth 33, and then the torsion spring 34 can drive the winding roller 32 to rotate back to its original position under the elastic force, and the winding roller 32 can roll and store the covering cloth 33.

[0081] Embodiment Six:

[0082] On the basis of Embodiment Five, further:

[0083] It further includes a wireless communication module, a signal processing module, a sensor module and a control module integrated inside the digital photo frame body 5;

[0085] The sensor module includes an attitude sensor for detecting the tilt angle and orientation of the digital photo frame body 5 and an ambient light sensor for detecting the ambient light intensity around and automatically adjusting the brightness;

[0086] The control module automatically adjusts the display angle and content layout of the digital photo frame body 5 according to the information detected by the sensor module.

[0087] In use, the wireless communication module supports Wi-Fi and Bluetooth connections and can be wirelessly paired with and transfer data to devices such as mobile phones, tablets, and computers. The signal processing module decodes and processes the received screen mirroring signal to ensure that the content can be clearly and smoothly displayed on the display screen of the digital photo frame body 5.

[0088] The attitude sensor continuously detects the attitude information of the digital photo frame body 5 and feeds the data back to the control module. The control module controls the rotation of the threaded rod 11 in the adjustment mechanism according to the attitude information. The rotation of the threaded rod 11 drives the T-shaped block 8 to move towards or away from each other, thereby adjusting the display angle of the digital photo frame body 5 to ensure that the digital photo frame body 5 reaches the optimal display angle.

[0089] At the same time, the control module controls the transmission of the first disk 18 and the second disk 20 in the transmission mechanism, so that the annular plate 2 can drive the digital photo frame body 5 to rotate in all directions under the action of the first transmission block 19 and the second transmission block 21, realizing that people can view the content displayed on the digital photo frame body 5 at any position.

[0090] In addition, the ambient light sensor detects the light intensity of the surrounding environment. The control module automatically adjusts the brightness of the digital photo frame body 5 according to the information detected by the sensor module to adapt to different environmental conditions and improve the viewing experience.

[0091] Furthermore, it is realized that in the actual use process of the existing device, the digital photo frame can be automatically adjusted to rotate in all directions, which is convenient to use and better than traditional products.

[0092] The standard parts used in this embodiment can be directly purchased from the market.
