Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and particularly to a lint filtering device and a drying device. Background Art

[0002] During the operation of a drying device, fluff and lint on clothes inevitably enter the air duct along with the flow of hot air. If not processed, these fluff or lint are likely to adhere to components such as the inner wall of the air duct or the fan in the air duct. Over time, it will block the air duct or affect the normal operation of the internal components of the air duct. To solve this problem, the prior art sets a lint filtering device in the air duct to block and retain the fluff and lint in the air on the lint filtering device. With the use of the drying device, a large amount of fluff and lint accumulating on the lint filtering device will block the air flow, resulting in a decrease in the drying efficiency of the drying device, a deterioration of the drying effect, and frequent alarms of the drying device. Therefore, it is necessary to clean the lint filtering device in time to ensure the normal operation of the drying device. The drying devices in the prior art usually extend the cleaning cycle by increasing the filter net area. However, the increase in the filter net area will cause the lint filtering device to occupy a large space, and when cleaning the lint filtering device in the prior art, it is necessary to pull out the lint filtering device from the drying device, which is time-consuming and laborious.

[0003] Therefore, there is an urgent need for a lint filtering device and a drying device to solve the problems in the prior art. Summary of the Invention

[0004] The purpose of the present invention is to provide a lint filtering device that can automatically clean the lint on the filter net after drying is completed, ensure smooth flow of hot air, and save the cleaning time.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] A lint filtering device, comprising:

[0007] A mounting plate;

[0008] A filtering assembly, including a mounting frame and a filter net. The first end of the mounting frame is rotatably connected to the mounting plate. The filter net is arranged in the mounting frame. When the mounting frame is in the lint collection position, the height of the first end of the filter net (220) is lower than the height of the second end of the filter net. When the mounting frame is in the lint cleaning position, the height of the first end of the filter net is higher than the height of the second end of the filter net;

[0009] A cleaning assembly, slidably connected to the mounting frame. The cleaning end of the cleaning assembly abuts against the filter net. The moving direction of the cleaning assembly is parallel to the filter net;

[0010] A collection bin, oppositely arranged relative to the rotation axis of the mounting frame;

[0011] A switching component, which is used to switch the installation frame between the lint collection position and the lint cleaning position, so that the cleaning component moves along the filter screen under its own weight to sweep the lint on the filter screen into the collection bin.

[0012] Before the drying starts, the switching component switches the collection frame to the lint collection position, and the height of the first end of the filter screen is lower than the height of the second end of the filter screen, so that the cleaning component moves along the filter screen to the first end of the filter screen under its own weight; after the drying is completed, the switching component switches the collection frame to the lint cleaning position, and the height of the first end of the filter screen is higher than the height of the second end of the filter screen, so that the cleaning component moves along the filter screen to the second end of the filter screen under its own weight, so as to sweep the lint on the filter screen from the second end of the filter screen into the collection bin, thereby cleaning the lint on the filter screen, ensuring smooth flow of hot air, reducing the possibility of frequent alarms of the drying equipment, and improving the stability and reliability of the drying equipment. The lint cleaning device has a compact structure, occupies a small space, and does not need to extract the lint filtering device from the drying equipment during the whole cleaning process, saving cleaning time.

[0013] Optionally, the switching component includes a metal part and an electromagnet. One of the metal part and the electromagnet is arranged on the mounting plate, and the other of the metal part and the electromagnet is arranged on the installation frame. When the electromagnet is powered on or powered off, the metal part is attracted to or separated from the electromagnet, so that the installation frame rotates around the rotation axis. Before the drying starts, the electromagnet is powered on, the metal part is attracted to the electromagnet, and the installation frame rotates around the rotation axis to a position where the height of the right end of the installation frame is lower than the height of the left end. The cleaning component slides from the left end of the installation frame to the right end under its own gravity; when the drying is completed, the electromagnet is powered off, the metal part is separated from the electromagnet, and the installation frame rotates around the rotation axis to a position where the height of the right end of the installation frame is higher than the height of the left end. The cleaning component slides from the right end of the installation frame to the left end under gravity, thereby realizing the cleaning of the filter screen, removing the accumulated fluff and lint on the filter screen, ensuring smooth air ducts, and improving the drying effect.

[0014] Optionally, along the direction from the first end to the second end of the mounting frame, the depth of the mounting frame gradually decreases. The filter screen is attached to the bottom surface of the mounting frame. When the electromagnet is energized, the mounting frame rotates around the rotation axis until the upper surface of the mounting frame is attached to the horizontally arranged mounting plate, and the cleaning assembly moves from the second end of the filter screen to the first end of the filter screen. The structure of this mounting frame is such that when the upper surface of the mounting frame is attached to the horizontally arranged mounting plate, the height of the first end of the filter screen is lower than that of the second end of the filter screen. Under the gravity of the cleaning assembly, the cleaning assembly moves along the filter screen to the first end of the filter screen, ensuring that during the drying process, the cleaning assembly is always at the first end of the filter screen, preventing the cleaning assembly from affecting air flow and improving the drying effect and efficiency.

[0015] Optionally, a collection port is provided at the top of the collection bin, and a lint outlet is provided at the second end of the mounting frame. When the electromagnet is de-energized, the mounting frame rotates around the rotation axis and is lapped on the collection bin. The collection port of the collection bin is communicated with the lint outlet, and the cleaning assembly moves from the first end of the mounting frame to the second end of the mounting frame. During this process, the cleaning end of the cleaning assembly cleans the fluff and lint on the filter screen, and pushes the fluff and lint on the filter screen into the collection bin through the lint outlet, thus completing the automatic cleaning and collection of lint, saving the time for lint cleaning, improving the lint cleaning efficiency, ensuring the cleanliness of the filter screen and the smoothness of the air duct, and improving the drying effect.

[0016] Optionally, a support plate is provided at the collection port. The support plate is inclined towards the inside of the collection bin. The mounting frame is lapped on the collection bin, and the support plate is attached to the filter screen. The setting of the support plate can provide a larger support area, ensuring that the mounting frame and the filter screen are more stable during the process of cleaning the filter screen, so as to improve the cleaning effect.

[0017] Optionally, the cleaning assembly includes a cleaning brush. The mounting frame further includes at least one slide rail, which is arranged on the side wall of the mounting frame parallel to the filter screen. The cleaning brush is provided with a sliding part, and the sliding part is slidably connected to the slide rail. The setting of the slide rail provides a guiding direction for the movement direction of the cleaning brush, ensuring that the movement of the cleaning brush is more stable and efficient, and improving the cleaning effect.

[0018] Optionally, the filter assembly includes a limiting plate, which is arranged at the second end of the mounting frame. The limiting plate is used to prevent the cleaning brush from slipping out of the second end of the mounting frame, thereby improving the safety of the filter assembly.

[0019] Optionally, the lint filtering device further includes a baffle, which is vertically arranged on the mounting plate, and the second end of the mounting frame can be attached to the baffle to prevent lint from overflowing from the lint outlet during the drying process, improving the filtering effect of the filtering component and maintaining the cleanliness of the drying equipment at the same time.

[0020] Optionally, the filtering component further includes a sealing ring, which is arranged on the top surface of the mounting frame and is used to seal the connection between the mounting frame and the mounting plate. This prevents lint from overflowing from the connection between the mounting frame and the mounting plate during the drying process, effectively improving the filtering effect of the lint filtering device.

[0021] The purpose of the present invention is to provide a drying equipment that can filter and collect lint in the air duct of the machine body, and automatically clean the lint after drying is completed to ensure the smoothness of the air duct, guarantee the efficient operation of the dryer, and optimize the user experience.

[0022] To achieve this purpose, the present invention adopts the following technical solutions:

[0023] A drying equipment, including the above-mentioned lint filtering device of the machine body, and the lint filtering device is arranged on the air duct of the machine body.

[0024] Beneficial effects:

[0025] The lint filtering device provided by the present invention includes a mounting plate, a filtering component, a cleaning component, a collection bin and a switching component. The filtering component includes a mounting frame and a filter net. The first end of the mounting frame is rotatably connected to the mounting plate, and the filter net is arranged inside the mounting frame. When the mounting frame is in the lint collection position, the height of the first end of the filter net is lower than the height of the second end of the filter net. When the mounting frame is in the lint cleaning position, the height of the first end of the filter net is higher than the height of the second end of the filter net; the cleaning component is slidably connected to the mounting frame, the cleaning end of the cleaning component abuts against the filter net, and the moving direction of the cleaning component is parallel to the filter net; the collection bin is arranged opposite to the rotation axis of the mounting frame; the switching component is used to switch the mounting frame to the lint collection position or switch the mounting frame to the lint cleaning position, so that the cleaning component moves along the filter net under its own weight to sweep the lint on the filter net into the collection bin.

[0026] Before the drying starts, the switching component switches the collection box to the lint collection position, and the height of the first end of the filter net is lower than the height of the second end of the filter net, so that the cleaning component moves along the filter net to the first end of the filter net under its own weight; after the drying is completed, the switching component switches the collection box to the lint cleaning position, and the height of the first end of the filter net is higher than the height of the second end of the filter net, so that the cleaning component moves along the filter net to the second end of the filter net under its own weight, so as to sweep the lint on the filter net from the second end of the filter net into the collection bin, thereby cleaning the lint on the filter net, ensuring smooth flow of hot air, reducing the possibility of frequent alarms of the drying equipment, and improving the stability and reliability of the drying equipment. The lint cleaning device has a compact structure, occupies a small space, and does not need to pull out the lint filtering device from the drying equipment during the whole cleaning process, saving cleaning time.

[0027] The drying equipment provided by the present invention includes a machine body and the above-mentioned lint filtering device. The lint filtering device is arranged on the air duct of the machine body. The lint filtering device can filter and collect the lint in the air duct, and automatically clean the lint after the drying is completed, ensuring the smoothness of the air duct, guaranteeing the efficient operation of the dryer, and optimizing the user experience.

[0043] This embodiment provides a lint filtering device, as Figures 1-5As shown, the lint filtering device includes a mounting plate 100, a filtering component 200, a cleaning component 300, a collection bin 500, and a switching component 400. The filtering component 200 includes a mounting frame 210 and a filter screen 220. The first end of the mounting frame 210 is rotatably connected to the mounting plate 100. The filter screen 220 is disposed within the mounting frame 210. When the mounting frame 210 is in the lint collection position, the height of the first end of the filter screen 220 is lower than the height of the second end of the filter screen 220. When the mounting frame 210 is in the lint cleaning position, the height of the first end of the filter screen 220 is higher than the height of the second end of the filter screen 220. The cleaning component 300 is slidably connected to the mounting frame 210. The cleaning end of the cleaning component 300 abuts against the filter screen 220. The moving direction of the cleaning component 300 is parallel to the filter screen 220. The collection bin 500 is disposed opposite to the rotation axis of the mounting frame 210. The switching component 400 is used to switch the mounting frame 210 to the lint collection position or switch the mounting frame 210 to the lint cleaning position, so that the cleaning component 300 moves along the filter screen 220 under its own weight to sweep the lint on the filter screen 220 into the collection bin 500.

[0044] Before the drying starts, the switching component 400 switches the collection frame to the lint collection position, and the height of the first end of the filter screen 220 is lower than the height of the second end of the filter screen 220, so that the cleaning component 300 moves along the filter screen 220 under its own weight to the first end of the filter screen 220. After the drying is completed, the switching component 400 switches the collection frame to the lint cleaning position, and the height of the first end of the filter screen 220 is higher than the height of the second end of the filter screen 220, so that the cleaning component 300 moves along the filter screen 220 under its own weight to the second end of the filter screen 220, so as to sweep the lint on the filter screen 220 from the second end of the filter screen 220 into the collection bin 500, thereby cleaning the lint on the filter screen 220, ensuring smooth flow of hot air, reducing the possibility of frequent alarms of the drying equipment, and improving the stability and reliability of the drying equipment. The lint cleaning device has a compact structure, occupies a small space, and does not require the lint filtering device to be pulled out of the drying equipment during the entire cleaning process, saving cleaning time.

[0045] Optionally, the switching component 400 includes a metal part 410 and an electromagnet 420. The electromagnet 420 is disposed on the mounting plate 100, and the metal part 410 is disposed on the mounting frame 210. As Figure 3As shown, the right end of the installation frame 210 is rotatably connected to the installation plate 100. Therefore, the first end and the second end of the installation frame 210 are defined as the right end and the left end of the installation frame 210 respectively, and the first end and the second end of the filter screen 220 are defined as the right end and the left end of the filter screen 220 respectively. Before the drying starts, the electromagnet 420 is powered on, and the metal part 410 is attracted to the electromagnet 420. The installation frame 210 rotates around the rotation axis to a position where the height of the right end of the filter screen 220 is lower than the height of the left end of the filter screen 220. Under the action of gravity, the cleaning assembly 300 slides from the left end of the filter screen 220 to the right end of the filter screen 220 along the filter screen 220; when the drying is completed, the electromagnet 420 is powered off, the metal part 410 is separated from the electromagnet 420, the installation frame 210 rotates around the rotation axis to a position where the height of the right end of the filter screen 220 is higher than the height of the left end of the filter screen 220, and the cleaning assembly 300 slides from the right end of the filter screen 220 to the left end of the filter screen 220 along the filter screen 220 under the action of gravity, and pushes the lint from the left end of the filter screen 220 into the collection bin 500, so as to realize the cleaning and collection of the lint on the filter screen 220, ensure the smoothness of the air duct, and improve the drying effect.

[0046] Optionally, in this embodiment, metal parts 410 are respectively arranged on both sides of the installation frame 210, and an electromagnet 420 is arranged on the installation plate 100 corresponding to each metal part 410, so as to ensure that when the electromagnet 420 is powered on, the magnetic force received by the installation frame 210 is stronger and the stability of the installation frame 210 can be ensured. In this embodiment, the metal part 410 is an angle iron, and the angle iron has low cost and is strong and durable, which can improve the service life of the lint filtering device.

[0047] In another embodiment, the metal part 410 can be arranged on the installation plate 100, and the electromagnet 420 can be arranged on the installation frame 210. After the electromagnet 420 is powered on, the installation frame 210 can also be adsorbed on the installation plate 100, ensuring that the installation frame 210 is closely attached to the installation plate 100, ensuring the stability of the installation frame 210 during the drying process, and improving the drying effect.

[0048] Optionally, the filtering assembly 200 includes a rotating shaft 230. One end of the rotating shaft 230 is connected to the installation plate 100, and the other end of the rotating shaft 230 is rotatably connected to the installation frame 210. Specifically, the rotating shaft 230 in this embodiment is an L-shaped rotating shaft 230. One end of the L-shaped rotating shaft 230 is locked on the installation plate 100 by a nut, and the other end of the rotating shaft 230 is rotatably connected to the installation frame 210. By setting the L-shaped rotating shaft 230, the structure of the filtering assembly 200 can be made more compact, the occupied space of the filtering assembly 200 can be saved, and the space utilization rate inside the drying equipment can be improved.

[0049] Optionally, in other embodiments, the rotating shaft 230 is a linear rotating shaft 230. The linear rotating shaft 230 is fixed to the right end of the mounting frame 210, and the mounting frame 210 is rotatably connected to the mounting plate 100 through the rotating shaft 230. The switching assembly 400 includes a motor. The output shaft of the motor is coaxially fixed to the rotating shaft 230. The motor drives the mounting frame 210 to rotate around the rotating shaft 230, so that the heights of both ends of the filter net 220 in the mounting frame 210 change. The cleaning assembly 300 cleans the filter net 220 by its own gravity, and pushes the lint after cleaning into the collection bin 500.

[0050] Optionally, as Figures 1-3 shown, along the direction from the right end to the left end of the mounting frame 210, the depth of the mounting frame 210 gradually decreases. The filter net 220 fits on the bottom surface of the mounting frame 210. The electromagnet 420 is powered on, and the mounting frame 210 rotates clockwise around the rotation axis until the upper surface of the mounting frame 210 fits on the horizontally arranged mounting plate 100. At this time, the height of the right end of the filter net 220 is lower than the height of the left end of the filter net 220. Under the action of the gravity of the cleaning assembly 300, the cleaning assembly 300 moves along the filter net 220 from the left end of the filter net 220 to the right end of the filter net 220, ensuring that during the drying process, the cleaning assembly 300 is always at the right end of the filter net 220, avoiding the cleaning assembly 300 from affecting air flow, and improving the drying effect and drying efficiency.

[0051] Optionally, as Figures 3-4 shown, a collection port 510 is provided at the top of the collection bin 500. A lint outlet is provided at the second end of the mounting frame 210. The electromagnet 420 is powered off, and the mounting frame 210 rotates and overlaps with the collection bin 500. The collection port 510 of the collection bin 500 is communicated with the lint outlet. At this time, the height of the left end of the filter net 220 is higher than the height of the right end of the first filter net 220. The cleaning assembly 300 moves from the right end of the filter net 220 to the left end of the filter net 220. During this process, the cleaning end of the cleaning assembly 300 cleans the fluff and lint on the filter net 220, and pushes the fluff and lint on the filter net 220 into the collection bin 500 from the lint outlet, thereby completing the automatic cleaning and collection of lint, saving the time for lint cleaning, improving the lint cleaning efficiency, ensuring the cleanliness of the filter net 220 and the smoothness of the air duct, and improving the drying effect.

[0052] Optionally, a support plate 520 is provided at the collection port 510. The support plate 520 inclines towards the inside of the collection bin 500. The mounting frame 210 overlaps with the collection bin 500. The support plate 520 fits with the filter net 220, which can provide a larger support area, ensure that the mounting frame 210 and the filter net 220 are more stable during the process of cleaning the filter net 220, and improve the cleaning effect.

[0053] Optionally, a cleaning opening is provided at the bottom of the side surface of the collection bin 500. A cleaning door 530 is provided at the cleaning opening. The cleaning door 530 is hinged to the collection bin 500. After lint accumulates in the collection bin 500, the cleaning door 530 can be simply opened to clean the lint in the collection bin 500.

[0054] Specifically, before the drying starts, the upper surface of the mounting frame 210 fits on the horizontally arranged mounting plate 100. There is a first preset angle between the filter screen 220 on the bottom surface of the mounting frame 210 and the horizontal plane. At this time, the height of the right end of the filter screen 220 is lower than the height of the left end of the filter screen 220. Under the gravitational action of the cleaning assembly 300, the cleaning assembly 300 moves from the right end of the filter screen 220 to the left end of the filter screen 220; after the drying is completed, the electromagnet 420 loses power, and the mounting frame 210 rotates counterclockwise around the rotation axis until the second end of the mounting frame 210 overlaps with the collection bin 500. The height of the left end of the support plate 520 is lower than the height of the right end of the support plate 520. The angle between the support plate 520 and the horizontal plane is the second preset angle, and the angle between the filter screen 220 and the horizontal plane is the third preset angle. The second preset angle is equal to the third preset angle to ensure that the support plate 520 fits with the filter screen 220, ensuring a good support effect and at the same time ensuring that the inclination angle of the filter screen 220 is appropriate. At this time, the height of the left end of the filter screen 220 is lower than the height of the right end of the filter screen 220. Under the action of its own gravity, the cleaning assembly 300 moves from the right end of the filter screen 220 to the left end of the filter screen 220. During this process, the cleaning end of the cleaning assembly 300 sweeps the fluff and lint on the filter screen 220 from the lint outlet into the collection bin 500, completing the lint cleaning process.

[0055] Optionally, the range of the first preset angle is 2° - 10°. The degree of the second preset angle is 2° larger than the degree of the first preset angle. Thus, after the mounting frame 210 overlaps with the collection bin 500, the distance between the top surface of the mounting frame 210 and the mounting plate 100 is within the effective suction range of the electromagnet 420. After the cleaning is completed, the electromagnet 420 is energized, and the mounting frame 210 can quickly rotate so that the angle iron is attracted to the electromagnet 420. At this time, the top surface of the mounting frame 210 fits on the mounting plate 100, preparing for the next drying process.

[0056] In this embodiment, the first preset angle is 2°. Before the drying starts, it is ensured that the cleaning assembly 300 is located at the right end of the filter screen 220. After the drying is completed, the electromagnet 420 loses power, the mounting frame 210 rotates and overlaps on the collection bin 500, and the filter screen 220 fits against the support plate 520. At this time, the support plate 520 is bent downward by 4°, that is, the angle between the filter screen 220 and the horizontal plane is also 4°, ensuring that the inclination angle of the filter screen 220 is appropriate, and the cleaning brush 310 can slide from the right end of the filter screen 220 to the left end by its own gravity. And at this time, the included angle between the top surface of the mounting frame 210 and the mounting plate 100 is 6°, ensuring the effective suction distance of the electromagnet 420.

[0057] Optionally, as Figures 4-5 shown, the cleaning assembly 300 includes a cleaning brush 310. The mounting frame 210 further includes at least one slide rail 211. The slide rail 211 is arranged on the side wall of the mounting frame 210 parallel to the filter screen 220. The cleaning brush 310 is provided with a sliding part, and the sliding part is slidably connected to the slide rail 211. The arrangement of the slide rail 211 provides a guide for the movement direction of the cleaning brush 310, ensuring that the movement of the cleaning brush 310 is more stable and efficient, and improving the cleaning effect.

[0058] Specifically, the sliding part includes rollers 311 and a roller shaft 312. The roller shaft 312 horizontally penetrates the cleaning brush 310, and a roller 311 is provided at each end of the roller shaft 312. A slide rail 211 parallel to the filter screen 220 is provided on each of the opposite side walls of the mounting frame 210, and each roller 311 is slidably connected to the corresponding slide rail 211, reducing the movement resistance of the cleaning brush 310, thereby ensuring that the movement process of the cleaning brush 310 is more stable and improving the cleaning effect.

[0059] Optionally, in this embodiment, a weight is provided inside or outside the cleaning brush 310 to ensure that after the slide rail 211 is inclined, it slides along the slide rail 211 by the own gravity of the cleaning brush 310, improving the reliability of the cleaning assembly 300.

[0060] Optionally, the filtering assembly 200 includes a limiting plate 240. The limiting plate 240 is arranged at the lint outlet, and the limiting plate 240 is used to prevent the cleaning brush 310 from disengaging from the slide rail 211, improving the safety of the filtering assembly 200.

[0061] Optionally, the lint filtering device further includes a baffle 110. The baffle 110 is vertically arranged on the mounting plate 100. After the electromagnet 420 is energized, the angle iron is attracted to the electromagnet 420. At this time, the top surface of the mounting frame 210 fits against the mounting plate 100, and the second end of the mounting frame 210 fits against the baffle 110. The baffle 110 blocks the lint outlet, preventing lint from overflowing during the drying process, improving the filtering effect of the filtering assembly 200, and maintaining the cleanliness of the drying equipment at the same time.

[0062] Optionally, the filtering component 200 further includes a sealing ring disposed on the top surface of the mounting frame 210. The sealing ring is used to seal the connection between the mounting frame 210 and the mounting plate 100, preventing lint from overflowing from the connection between the mounting frame 210 and the mounting plate 100 during the drying process, effectively improving the filtering effect of the lint filtering device.

[0063] Specifically, when the lint filtering device provided in this embodiment is in use, it includes:

[0064] Lint collection process: When the machine is drying, the electromagnet 420 is energized and has strong magnetism. The electromagnet 420 attracts the angle iron, pulling the filtering component 200 to fit with the mounting plate 100. The front part of the filtering component 200 fits with the baffle 110. The slide rail 211 is parallel to the filter net 220. The height of the right end of the slide rail 211 is lower than the height of the left end of the slide rail 211. At this time, the cleaning component 300 of the lint filtering device slides along the slide rail 211 to the right end of the filtering component 200 under the action of its own weight on the roller 311. When the lint passes through the filtering component 200, it is collected by the filter net 220.

[0065] Lint cleaning process: After the machine finishes drying, the electromagnet 420 is de-energized and loses its magnetism. At this time, the filtering component 200 sags around the rotating shaft 230 under the action of its own weight. The left end of the filter net 220 is lapped on the support plate 520 of the collection bin 500. At this time, the cleaning component 300 slides to the left end of the filtering component 200 under the action of its own weight on the roller 311. During the sliding process, the filter net 220 is cleaned once, and the lint collected during the drying process is swept into the interior of the collection bin 500 through the collection port 510 of the collection bin 500, completing the lint cleaning.

[0066] This embodiment also provides a drying device, including a machine body and the above-mentioned lint filtering device. The lint filtering device is disposed on the air duct of the machine body. The lint filtering device can filter and collect the lint in the air duct, and automatically clean the lint after drying is completed, ensuring the smoothness of the air duct, guaranteeing the efficient operation of the dryer, and optimizing the user experience.

[0067] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
