[0002] Suspended particles in the air (PM2.5, PM10, etc.) have caused significant harm to the environment and human health. In order to improve air quality and reduce particulate pollution, various air filtration devices are widely used in air treatment. Among them, dust bag dust collectors have become important equipment in the field of industrial dust removal due to their high filtration efficiency and wide range of applications.

[0003] However, the dust bag type dust collector in the prior art has some technical problems during use, which limits its application effect in atmospheric treatment. Especially in a humid air environment, the surface of the dust bag easily absorbs moisture, causing the dust to stick to the dust bag, resulting in dust agglomeration. Dust agglomeration not only increases the difficulty of cleaning the dust bag, but also may reduce the filtration efficiency. Furthermore, when performing recoil cleaning, the recoil device of the prior art is difficult to provide an appropriate recoil force, which can neither effectively remove the dust on the surface of the dust bag nor cause damage to the dust bag due to excessive recoil force, seriously affecting the service life and operational stability of the equipment.

[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

[0021] like Figures 1 to 4 As shown, the first embodiment of the present invention provides an air filter device for atmospheric treatment, comprising: A chamber body 1 having a first cavity 101 and a second cavity 102; An air outlet pipeline 201 is provided in the first cavity 101, and an air inlet pipeline 202 is provided in the second cavity 102; The dust filter assembly 3 is arranged in the first cavity 101; A recoil assembly 4, connected to the first cavity 101, and configured to provide recoil gas to the first cavity 101; The adjustment component 5 is arranged in the first cavity 101; The dust filter assembly 3 at least includes a plurality of dust removal bags 301 with square cross sections; Wherein, the air outlet of the recoil assembly 4 is located between adjacent dust removal bags 301; The adjustment component 5 is configured to apply a tensile force to a group of opposite sides of the dust bag 301, so that the spacing between the opposite sides of the group is larger than the initial spacing, and the spacing between the other group of opposite sides is smaller than the initial spacing.

[0022] In this embodiment, the air inlet pipe 202 is used to guide external air into the warehouse body 1. The air inlet pipe 202 is connected to the fan so that the air can be quickly introduced into the second cavity 102. When the air flows in the second cavity 102, since the dust particles are heavier than the gas, the dust particles will settle downward, and the lighter gas will rise to the first cavity 101. When the air contacts the dust filter assembly 3, the dust first adheres to the outer surface of the dust bag 301, thereby performing preliminary filtration. The clean air continues to enter the interior of the dust bag 301, and flows out through the opening at the top of the dust bag 301, and finally is discharged from the warehouse body 1 through the air outlet pipe 201. The air outlet pipe 201 can be connected to the exhaust fan to further enhance the exhaust effect.

[0023] On this basis, an adjustment component 5 is further added to change the shape of the dust bag 301. The initial cross-section of the dust bag 301 is a square, and its four sides are roughly equal in length. Under the action of the adjustment component 5, the spacing between one set of relative sides is stretched to be larger than the initial spacing, while the spacing between another set of relative sides is reduced to be smaller than the initial spacing. In this way, the cross-section of the dust bag 301 becomes a rectangle, and the surface of the dust bag 301 changes from the original square to a sheet-like structure. The key technical effect of this structural change is to improve the efficiency during the recoil process, because the sheet-like surface of the dust bag 301 has a larger contact area with the recoil gas, which helps to increase the impact force of the recoil gas and is beneficial to the peeling of attached dust.

[0024] The air outlet of the recoil assembly 4 is located between adjacent dust bags 301, and the recoil gas can directly act on the surface of the dust bag 301, especially the dust and lumps attached to the outer layer of the dust bag 301. In this process, the surface of the sheet-like dust bag 301 will be directly impacted by the recoil gas, thereby improving the dust removal efficiency. According to Bernoulli's principle, when the airflow flows on the surface, the area with higher flow rate will produce lower air pressure. The application of this principle allows the airflow to produce a local vibration effect on the surface of the dust bag 301 when it flows on the surface of the sheet-like dust bag 301.

[0025] Specifically, the airflow is ejected from the recoil assembly 4 and flows at high speed along the surface of the dust bag 301. The air pressure in the local area is lower than that in the surrounding area, thereby generating vibrations on the surface of the dust bag 301. These vibrations can not only loosen the dust attached to the surface of the dust bag 301, but also effectively promote the detachment of the dust due to the dual effects of the airflow and vibration, especially the friction effect with the surface of the dust bag 301. The dust becomes looser under the purging and vibration of the recoil gas, and the stripping process is more efficient.

[0026] In addition, in a conventional dust bag filter, when the recoil gas directly enters the interior of the dust bag 301, the high pressure and strength of the airflow will cause the dust bag 301 to expand rapidly. This sudden deformation often produces severe mechanical pressure on the material of the dust bag 301, and even damages the dust bag 301, affecting its long-term performance. However, this embodiment sets the outlet of the recoil gas outside the dust bag 301, thereby preventing the airflow from directly entering the interior of the dust bag 301, reducing the internal and external pressure difference when the dust bag 301 expands, and significantly reducing the risk of damage to the dust bag 301.

[0027] Finally, the agglomerated dust will be discharged through the dust outlet at the bottom of the bin body 1. Through the efficient cooperation of the entire filtering and recoil cleaning system, the equipment can efficiently remove dust while reducing the risk of damage to the dust bag 301 and ensuring the long-term stable working state of the equipment.

[0028] Through the synergistic effect of the sheet-shaped dust bag 301 and the recoil gas, the attached and agglomerated dust can be removed more efficiently. The vibration generated by the high-speed flow of the airflow can effectively promote the peeling of agglomerated dust, thereby enhancing the dust cleaning effect of the recoil gas. As the shape of the dust bag 301 changes, the process of the airflow passing through the surface of the dust bag 301 is optimized, making the dust filtering and removal more thorough.

[0029] like Figures 1 to 4 As shown, the second embodiment of the present invention provides an air filter device for atmospheric treatment, and based on the above embodiment, the dust filter component 3 includes: A mounting plate 302 connected to the first cavity 101; Wherein, the mounting plate 302 has multiple rows of first assembly holes and multiple rows of second assembly holes; The first assembly hole is configured to assemble the dust bag 301, and the bag body of the dust bag 301 is located below the mounting plate 302; The second assembly hole is configured as an air outlet for assembling the recoil assembly 4; Wherein, each row of second assembly holes is arranged between two adjacent rows of first assembly holes.

[0030] In this embodiment, the first assembly hole is used to assemble the dust bag 301 so that it can be stably suspended below the mounting plate 302, and the position of the dust bag 301 is ensured not to be offset by a fixed connection. At the same time, a sealed connection is adopted between the first assembly hole and the outlet of the dust bag 301 to ensure that the flow path of the filtered air is unique, that is, the air can only flow along the path of "external surface of the dust bag 301 → inside of the dust bag 301 → outlet of the dust bag 301". The sealed connection effectively prevents the leakage of unfiltered air, thereby ensuring the maximization of the filtering efficiency.

[0031] The second assembly hole is used to assemble the gas outlet of the recoil assembly 4. The recoil gas enters the gap of the dust removal bag 301 through the second assembly hole to reversely purge the dust attached to the outer surface of the dust removal bag 301.

[0032] In addition, the mounting plate 302 is firmly mounted on the inner wall surface of the first cavity 101 through a fixed connection and a sealed connection. The purpose of this sealed connection is to form a closed air filtration area to ensure that the air entering the first cavity 101 from below can only flow along a specified path and prevent the air without dust filtration from being directly discharged from the silo 1. This can effectively improve the filtration efficiency and avoid performance loss caused by uncertainty in the air flow path.

[0033] In addition, the outlet of the dust bag 301 is fixed to the mounting plate 302 through the first assembly hole and is sealed. Ensure that the outlet of the dust bag 301 maintains the initial square shape so that the filtered air can be discharged smoothly. In addition, the adjustment component 5 only acts on the bag body of the dust bag 301 to drive it to change its shape. For example, the shape of the bag body can be changed from a cross-section close to a square to a sheet structure with a rectangular cross-section. The change in shape can enhance the responsiveness of the surface of the dust bag 301 to the recoil gas, effectively weaken the adhesion between the dust and the surface of the dust bag 301, thereby improving the cleaning efficiency.

[0034] like Figures 4 to 6 As shown, the third embodiment of the present invention provides an air filter device for atmospheric treatment, and based on the above embodiment, the adjustment component 5 includes: The linkage rod 501 is disposed inside the bag body of the dust removal bag 301, and the end of the linkage rod 501 is located below the mounting plate 302; The driving rod 502 is connected to the linkage rod 501 through an elastic element; A driving component 503 connected to the driving rod 502; The driving component 503 can perform a first driving motion and a second driving motion, and the driving rod 502 is controlled by the first driving motion and the second driving motion to drive the linkage rod 501 to switch between the first state and the second state; The first state is configured to make the bag body of the dust removal bag 301 in an initial state; The second state is configured to deform the bag body of the dust removal bag 301, wherein the spacing between one set of opposite sides is larger than the initial spacing, and the spacing between the other set of opposite sides is smaller than the initial spacing.

[0035] In this embodiment, the linkage rod 501 is arranged inside the bag body of the dust bag 301, and directly acts on the inner wall surface of the bag body of the dust bag 301, so that the dust bag 301 can be changed according to the predetermined shape requirements. The end of the linkage rod 501 is located below the mounting plate 302. Through this position arrangement, the adjustment function can be fully exerted without interfering with the operation of other components. The installation method of the linkage rod 501 inside the dust bag 301 ensures the precise control of the deformation of the dust bag 301, while avoiding the influence of the external environment on the adjustment component 5.

[0036] The driving rod 502 is connected to the linkage rod 501 through an elastic element (such as a spring). This connection method has the dual advantages of buffering and flexible adjustment. On the one hand, the elastic element can absorb the excessive impact force that may be generated during the movement of the driving rod 502 to avoid damage to the linkage rod 501 and the dust bag 301; on the other hand, the elastic force of the elastic element provides flexible support for the adjustment process, making the shape change of the dust bag 301 more stable and controllable.

[0037] The driving component 503 is connected with the driving rod 502 to perform the first driving motion and the second driving motion, thereby realizing precise control of the linkage rod 501. Specifically: The first driving motion acts on the linkage rod 501, so that the bag body of the dust removal bag 301 is in an initial shape, that is, a shape with a cross section close to a square and roughly equal sides, to ensure normal operation during the filtering process.

[0038] The second driving motion causes the linkage rod 501 to shift, thereby driving the dust bag 301 to deform. The spacing of one set of opposite sides is stretched to be larger than the initial spacing, and the spacing of the other set of opposite sides is reduced to be smaller than the initial spacing, thereby changing the cross section of the dust bag 301 to a rectangular or sheet-like structure. This morphological change optimizes the surface characteristics of the dust bag 301, which is more conducive to the subsequent recoil cleaning effect.

[0039] In the initial form, the cross-sectional shape of the dust removal bag 301 is stable, and the side length is relatively uniform, which can provide a maximized effective filtration area for air filtration.

[0040] In the deformed state, the dust bag 301 can generate a vibration effect with the help of the impact force of the recoil gas, making it easier to peel off the stubborn dust and agglomerated dust on the surface of the dust bag 301.

[0041] Through the coordinated work of the driving component 503, the driving rod 502, the linkage rod 501 and the elastic element, the adjustment component 5 can flexibly switch between different states to achieve precise control of the shape of the dust bag 301, which is specifically embodied as follows: The change in the shape of the dust bag 301 cooperates well with the effect of the recoil gas, which greatly improves the efficiency of the agglomerated dust being separated from the surface of the dust bag 301.

[0042] The flexible adjustment of the shape of the dust bag 301 enables the device to adapt to the operating requirements under different air conditions, especially in humid or high dust concentration environments, and can still maintain efficient operation.

[0043] In addition, during the transition of the dust bag 301 from a square shape to a sheet shape, since the linkage rod 501 of the adjustment assembly 5 is always in contact with the wall surface of the dust bag 301, the movement of the linkage rod 501 promotes the loosening of dust on the surface of the dust bag 301, thereby helping to detach dust from the surface of the dust bag 301.

[0044] like Figures 4 to 6 As shown, the fourth embodiment of the present invention provides an air filter device for atmospheric treatment, and based on the above embodiment, the driving component 503 includes: a first driving unit and a second driving unit; The first driving part is connected to a pair of driving rods 502 located on the same side of the dust bag 301, and the driving rods 502 are connected to the linkage rods 501 on the same side; The second driving part is connected to another pair of driving rods 502 located on the same side of the dust bag 301, and the driving rods 502 are connected to the linkage rods 501 on the same side; The same side refers to the side of the dust bag 301 that is perpendicular to the movement direction of the first driving movement and the second driving movement; Furthermore, when the first driving part and the second driving part perform the first driving motion and the second driving motion, the moving directions thereof are opposite.

[0045] In this embodiment, the first driving unit is connected to a pair of driving rods 502 on the same side of the dust bag 301, and is connected to the linkage rod 501 on the side through the driving rod 502. The main function of the first driving unit is to drive the corresponding driving rod 502 to displace, so that the driving rod 502 drives the linkage rod 501 connected to it to move closer or farther away from each other, so that the wall surface of the dust bag 301 in contact with the linkage rod 501 changes adaptively (meaning that the width increases or decreases). Correspondingly, the second driving unit is similar, and finally makes the linkage rod 501 connected to the second driving unit move closer or farther away from each other, so that the wall surface of the dust bag 301 in contact with the linkage rod 501 changes adaptively (meaning that the width increases or decreases). Through the coordination of the first driving unit and the second driving unit, the relative movement of the two pairs of linkage rods 501 will cause the overall shape of the dust bag 301 to change, that is, switch between a square structure and a sheet structure.

[0046] The "same side" specifically refers to the side of the dust bag 301 that is perpendicular to the first driving motion and the second driving motion. By this definition, the driving component 503 can accurately act on a specific part of the dust bag 301, thereby avoiding unnecessary force dispersion or structural interference.

[0047] In the initial state, the cross section of the dust removal bag 301 is approximately square, and the lengths of the sides are equal or nearly equal.

[0048] When the first drive unit and the second drive unit start to work, the distance between one set of relative sides of the dust bag 301 gradually increases under the action of the first drive unit, while the distance between the other set of relative sides gradually decreases under the action of the second drive unit. Finally, the cross section of the dust bag 301 becomes a rectangular or sheet-like structure. The sheet-like structure allows the recoil gas to cover the surface of the dust bag 301 more evenly, and as mentioned above, it is more conducive to the formation of high-frequency vibration on the outer surface of the dust bag 301, thereby improving the cleaning efficiency.

[0049] In a specific implementation, there are four linkage rods 501 and correspondingly, there are four driving rods 502.

[0050] like Figure 5 to Figure 6 As shown, the fifth embodiment of the present invention provides an atmosphere treatment air filtering device, and on the basis of the above embodiment, the first driving part and the second driving part have the same structure, and the first driving motion and the second driving motion are linear motions, and each driving part includes: A driving member 5031 connected to a side wall surface of the first cavity 101; The driving frame 5032 is connected to the driving member 5031 and is controlled by the driving member 5031 to generate linear motion.

[0051] In this embodiment, each driving part includes a driving member 5031, and the driving member 5031 is fixedly connected to the side wall surface of the first cavity 101. The driving member 5031 is the power core of the entire driving system, and drives the dynamic change of the bag shape by providing linear motion.

[0052] The driving frame 5032 is connected to the driving member 5031 and performs linear motion under the control of the driving member 5031, thereby ensuring the directionality and stability of the motion and avoiding possible damage to the cloth bag due to unstable motion trajectory in traditional designs.

[0053] The driving member 5031 drives the driving frame 5032 to perform linear motion along a predetermined direction by means of electric, pneumatic or hydraulic power. The first driving part and the second driving part act on different opposite sides of the cloth bag respectively. When the driving member 5031 generates linear motion, the driving frame 5032 drives the linkage rod 501 of the cloth bag through the driving rod 502, so that the distance between the opposite sides of the cloth bag changes, thereby adjusting the shape of the cloth bag.

[0054] Linear motion can provide precise and controllable displacement, making the shape change of the bag smoother and more stable, avoiding irregular deformation or impact force that may be caused by nonlinear motion.

[0055] In a specific implementation, the driving frame 5032 is a frame structure, and the driving rod 502 corresponding to each dust removal bag 301 is connected to the driving frame 5032 .

[0056] like Figure 6 As shown, the sixth embodiment of the present invention provides an air filter device for atmospheric treatment, and based on the above embodiment, the driving rod 502 includes: The first driving rod 5021 is slidably connected to the driving frame 5032; A second driving rod 5022 connected to the first driving rod 5021; Furthermore, the linkage rod 501 is connected to the second driving rod 5022; The second driving rod 5022 includes a pair of cross rods, and the pair of cross rods are cross-arranged and hinged at the intersection, and the ends of the cross rods are connected to the linkage rod 501.

[0057] In this embodiment, the second driving rod 5022 is connected to the first driving rod 5021, one end of which transmits force to the first driving rod 5021, and the other end acts on the bag body of the dust bag 301 through the connection with the linkage rod 501. This multi-stage connection transmits the movement of the driving frame 5032 to the linkage rod 501 step by step, thereby achieving effective adjustment of the bag shape.

[0058] The second driving rod 5022 includes a pair of cross rods that are arranged crosswise and hinged. The hinged form at the intersection allows a certain degree of freedom of movement between the two cross rods to achieve adaptive adjustment of the driving movement. The end of each cross rod is connected to the linkage rod 501, ensuring that the direction of force transmission is consistent with the requirements of the bag shape change, thereby achieving efficient movement conversion.

[0059] Taking the first driving part as an example, the specific working principle is that the driving end of the driving member 5031 extends or shortens, driving the driving frame 5032 to perform linear motion. During this process, the two first driving rods 5021 connected to the driving frame 5032 will move closer to or farther from each other along a direction perpendicular to the linear motion direction, thereby driving the ends of the cross-hinged cross rods to move closer to or farther from each other. During the process of moving closer to each other, the movement process of the linkage rod 501 is consistent with that of the ends of the cross rods, that is, they remain close to each other.

[0060] like Figure 6 to Figure 7 As shown, the seventh embodiment of the present invention provides an air filter device for atmosphere treatment, and based on the above embodiments, the cross rod includes a sleeve rod 1 50221 and a sleeve rod 2 50222; The sleeve rod 1 50221 and the sleeve rod 2 50222 are slidably sleeved; Furthermore, the elastic element is disposed inside the first sleeve rod 50221 and applies an elastic force to the second sleeve rod 50222 away from the first sleeve rod 50221 .

[0061] In this embodiment, the sleeve rod 1 50221 and the sleeve rod 2 50222 are designed as a sliding sleeve structure, wherein the sleeve rod 1 50221 is an outer sleeve rod and the sleeve rod 2 50222 is an inner sleeve rod. The sliding sleeve allows the sleeve rod 2 50222 to slide freely inside the sleeve rod 1 50221, thereby realizing a retractable force transmission, which can adapt to different displacement requirements during the bag shape adjustment process and ensure that the force transmission is more flexible.

[0062] The elastic element is placed inside the sleeve rod 50221, and its main function is to provide elastic force.

[0063] One end of the elastic element is fixed inside the first sleeve rod 50221 , and the other end acts on the second sleeve rod 50222 to apply an elastic force to the second sleeve rod 50222 away from the first sleeve rod 50221 .

[0064] The change of the shape of the dust bag 301 is achieved through the coordinated action of the driving component 503 and the driving rod 502. The driving end of the driving component 5031 is extended or shortened, driving the driving frame 5032 to move in a linear direction. In this process, the first driving rod 5021 connected to the driving frame 5032 approaches or moves away from each other in a direction perpendicular to the linear motion direction, thereby driving the ends of the cross-hinged cross rods connected thereto to move synchronously. When the ends of the cross-hinged cross rods approach, the spacing between one set of relative edges of the dust bag 301 increases, and correspondingly, the spacing between the other set of relative edges decreases, that is, the shape of the dust bag 301 switches to a rectangular or sheet-like structure; when the ends of the cross-hinged cross rods move away, the two sets of relative edges of the dust bag 301 gradually return to the initial spacing. At the same time, the sleeve rod 1 50221 and the sleeve rod 2 50222 achieve relative sliding in this process, that is, the sleeve rod 2 50222 extends or retracts into the sleeve rod 1 50221 to adapt to the aforementioned changes.

[0065] like Figures 4 to 5 As shown, the eighth embodiment of the present invention provides an air filter device for atmospheric treatment, and based on the above embodiment, further includes: Sliding block 601 and sliding slot 602; The sliding groove 602 is formed on the driving frame 5032; The sliding block 601 is slidably connected to the sliding slot 602 , and an end of the first driving rod 5021 is connected to the sliding block 601 .

[0066] In this embodiment, the sliding of the sliding block 601 drives the end of the first driving rod 5021 connected thereto, causing the first driving rod 5021 to move relative to each other, thereby achieving the approach or distance of the first driving rod 5021 on the same side in a direction perpendicular to the linear movement direction of the driving frame 5032.

[0067] like Figure 2 As shown, the ninth embodiment of the present invention provides an air filter device for atmospheric treatment, and based on the above embodiment, the recoil assembly 4 includes: Recoil gas source 401; The recoil pipe 402 is connected to the recoil gas source 401 and extends into the first cavity 101 to communicate with the second assembly hole.

[0068] In this embodiment, the recoil gas source 401 provides high-pressure gas for removing dust attached to the surface of the dust bag 301. The recoil gas source 401 can be a compressed air device, a gas tank, etc., which can provide a stable and adjustable gas flow to meet different cleaning needs. The recoil pipe 402 is connected to the recoil gas source 401 and extends into the first cavity 101 to communicate with the second assembly hole. The function of the recoil pipe 402 is to guide the recoil gas from the gas source to the working area of ​​the dust bag 301 to ensure that the recoil gas can evenly cover the surface of the dust bag 301.

[0069] In a specific embodiment, the recoil assembly 4 includes: The valve system is connected to the recoil pipeline 402 or the recoil gas source 401 to open and close the introduction of the recoil gas.

[0070] During operation, when the atmospheric treatment air filter device is in a normal dust removal state, the recoil component 4 is in a closed state, no airflow passes through the recoil duct 402, and the adjustment component 5 adjusts the dust bag 301 to a square shape. The air passes through a normal airflow path (inlet pipe 202 → outer surface of the dust bag 301 → inside of the dust bag 301 → outlet of the dust bag 301 → outlet of the air duct 201) to complete the capture and filtration of particulate matter in the air.

[0071] When recoil cleaning is required, the adjustment component 5 adjusts the dust bag 301 to the shape of a sheet structure, the valve system opens, and the recoil gas source 401 introduces recoil gas into the first cavity 101 through the recoil pipe 402. The recoil gas flows between adjacent dust bags 301, and impacts the surface of the dust bag 301 through high-speed airflow, quickly blowing away the dust particles attached to the surface of the bag. Since the recoil gas has a high pressure and flow rate, it can not only effectively peel off the dust, but also cause the surface of the dust bag 301 to vibrate. Specifically, the impact force generated by the recoil gas on the surface of the bag causes the sheet structure of the bag to vibrate to a certain extent. This vibration effect can further enhance the dust shedding effect, especially when more stubborn dust is attached to the surface of the bag. The vibration can effectively break the adhesion between the dust and the surface of the bag, making the dust easier to be blown away. Through the dual effects of airflow and vibration, the recoil gas not only promotes the stripping of surface dust, but also ensures that each dust removal bag 301 can be cleaned evenly and efficiently, thereby improving the dust removal effect and working efficiency of the device.

[0072] Through the above process, the dust already attached to the surface of the dust bag 301 is peeled off and falls off under the impact of the recoil gas, and falls under the bin body 1 for unified collection and subsequent treatment. After the recoil cleaning is completed, the valve system is closed, and the adjustment component 5 adjusts the dust bag 301 to a square shape, and the atmospheric treatment air filter device enters the normal dust removal working state again, achieving efficient circulation operation.

[0073] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The above embodiments only express several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
