Description

[0001] This application is a divisional application of Chinese Patent Application No. 202310475568.8 entitled "A Floor Scrubber", the contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of cleaning equipment technology, and more particularly to a cleaning head assembly and a floor scrubber. Background Technology

[0003] A floor scrubber is a cleaning machine suitable for cleaning hard floors while simultaneously sucking up and removing wastewater from the site. It has advantages such as being environmentally friendly, energy-saving, and highly efficient. It includes a roller assembly for cleaning up debris on the floor and a cleaning brush assembly for sweeping up the debris adhering to the roller assembly.

[0004] In existing floor scrubber products, the roller assembly and the cleaning brush assembly are driven by different motors. When the floor scrubber is working, the roller and brush assemblies work synchronously. The dual motors will generate a lot of noise when working at high speeds. At the same time, the dual motors also reduce the standby time of the floor scrubber.

[0005] In the aforementioned prior art, such as the one disclosed in Chinese Patent CN218009602U, a separate drive motor provides driving force to drive the gear set to rotate, thereby driving the brush roller to rotate. The cleaning roller is driven by another separate drive motor, and the brush roller and the cleaning roller rotate in opposite directions. This is more conducive to the brush roller brushing off the sticky debris on the cleaning roller. However, the separate motor driving the brush roller consumes more electricity, reducing the battery life of the floor scrubber. Another example is the cleaning machine disclosed in Chinese Patent CN215605440U, which uses a drive assembly that simultaneously drives the roller and the cleaning brush to rotate to drive the entire cleaning machine. However, the installation structure of the cleaning brush in this solution is too complicated, making it difficult to easily remove the cleaning brush from the cleaning machine for thorough cleaning.

[0006] Therefore, how to increase the standby time of floor scrubbers while reducing their noise is a technical problem that urgently needs to be solved. Summary of the Invention

[0090] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0091] The following will describe the scheme of this application in detail with reference to the accompanying drawings.

[0092] As analyzed in the background section of this application, existing floor scrubbers have short standby times and high noise levels. To address these technical problems, this application provides a floor scrubber. Figures 1 to 5 As shown, a floor scrubber includes: a handle (not shown in the attached figure); a cleaning head assembly fixedly connected to the handle; wherein, the cleaning head assembly includes a housing and a motor, the motor being installed inside one side of the housing; the cleaning head assembly further includes a roller assembly sleeved on the motor, a transmission assembly disposed on the housing opposite the motor mounting location, and a brush assembly spanning between the two opposite sides of the housing, the motor driving the roller assembly to rotate, and the roller assembly and the brush assembly rotating synchronously via the transmission assembly.

[0093] The floor scrubber provided in this embodiment of the invention includes a handle and a cleaning head assembly fixedly connected to the handle. The cleaning head assembly may consist of a motor, a roller assembly, a transmission assembly, and a brush assembly. The motor can drive the roller assembly to rotate while simultaneously enabling the brush assembly to rotate synchronously with the roller assembly via the transmission assembly. This can increase the standby time of the floor scrubber without increasing its size, and also reduce the noise of the floor scrubber during operation.

[0094] In this embodiment, as Figure 1 , Figure 2 , Figure 9 , Figure 10 , Figure 11 As shown, the cleaning head assembly includes a housing 40 and a motor 10. The housing 40 includes a housing body 401, and a removable cover plate 404 is provided on the housing body 401. The handle is fixedly connected to the cleaning head assembly through the housing 40. The motor 10 is installed inside the housing 40 on one side. The cleaning head assembly also includes a roller assembly 11 sleeved on the motor 10, a transmission assembly 20 disposed on the housing opposite the motor mounting location (not shown in the figure), and a brush assembly 30 spanning the two opposite sides of the housing. When the motor 10 drives the roller assembly 11 to rotate inside the housing 40, the transmission assembly 20 rotates due to the rotation of the roller assembly 11. At the same time, the brush assembly 30 also achieves directional rotation due to the rotation of the transmission assembly 20. Thus, by setting a motor 10 inside the housing 40, the roller assembly 11 and the brush assembly 30 can be rotated synchronously, thereby increasing the standby time of the floor scrubber and reducing the noise of the floor scrubber in the working state.

[0095] In some embodiments, such as Figure 1 , Figure 2 , Figure 9 , Figure 10 , Figure 11As shown, the housing 40 also includes a first side plate 402 and a second side plate 403. The first side plate 402 is integrally formed with the housing body 401. The motor 10 is mounted on the side of the first side plate 402 facing the inside of the housing 40 via a rotatable support (not shown in the figure). A gap area (not shown in the figure) is provided between the first side plate 402 and the second side plate 403. One end of the roller assembly 11 can be sleeved on the outer edge of the motor 10. The output end coupling (not shown in the figure) of the motor 10 drives the roller component 110 of the roller assembly 11 to rotate. The outer wall of the roller component 110 is sleeved with a roller wiping layer 111. The roller wiping layer 111 rotates with the roller component 110 and the two do not slide against each other. The roller assembly 11 is detachably installed in the gap area, which makes the maintenance of components such as the motor 10 simpler and also saves the manufacturing cost of the floor scrubber.

[0096] In some embodiments, the first side plate 402 and the second side plate 403 are respectively disposed on two opposite sides of the housing body 401 of the cleaning head assembly, that is, the housing body 401 of the cleaning head assembly is disposed in a gap area formed between the first side plate 402 and the second side plate 403. The second side plate 403 is detachably fixedly connected to the housing body 401. The roller assembly 11 is respectively engaged with the first side plate 402 and the second side plate 403 in the gap area, thereby making it easier to assemble and disassemble the roller assembly 11.

[0097] In some embodiments, such as Figure 3 , Figure 4 , Figures 7 to 11 As shown, the roller assembly 11 includes a roller component 110 and a first gear component 12, and the transmission assembly 20 includes a first gear component 12 and a second gear component 201; wherein, the first gear component 12 is fixedly connected to the roller component 110 and is pulsatorically connected to the second gear component 201; the second gear component 201 is pulsatorically connected to the brush assembly 30.

[0098] In this embodiment, during the rotation of the roller 110, the first gear 12 and the second gear 201 also rotate in a specific direction along with the roller 110. The brush assembly 30 also rotates in a specific direction along with the second gear 201 when the second gear 201 rotates in that direction. The first gear 12 can be detachably and fixedly connected to the roller 110 to facilitate the assembly and disassembly of the roller 110.

[0099] Furthermore, in Figures 7 to 9In the embodiment shown, the transmission assembly 20 further includes a third gear 302, and the brush assembly 30 includes a brush body 301 and a third gear 302; wherein the brush body 301 and the third gear 302 are detachably fixedly connected, and the third gear 302 is drively connected to the second gear 201.

[0100] In some embodiments, such as Figure 2 , Figure 9 As shown, the second side plate 403 includes an inner second side plate layer 4031 integrally formed with the housing body 401, and an outer second side plate layer 4032 detachably connected to the housing body 401. The roller assembly engages with the first side plate 402 and the second side plate 403 respectively in the gap area, thereby facilitating the assembly and disassembly of the roller assembly 11.

[0101] In some embodiments, such as Figure 3 , Figure 4 , Figures 7 to 11 As shown, the roller assembly 11 includes a roller component 110 and a first gear component 12, and the transmission assembly 20 includes a first gear component 12 and a second gear component 201. The first gear component 12 is fixedly connected to the roller component 110 and is drive-connected to the second gear component 201. The second gear component 201 is drive-connected to the brush assembly 30. Both the first gear component 12 and the second gear component 201 protrude from the upper surface of the inner layer 4031 of the second side plate (facing the outer side of the housing body 401). The upper surface of the inner layer 4031 of the second side plate is also provided with a dam (not shown in the figure) surrounding the transmission assembly 20. A transmission assembly cover plate 113 is sealed over the dam, and the outer layer 4032 of the second side plate is sealed over the inner layer 4031 of the second side plate, which is covered by the transmission assembly cover plate 113.

[0102] In this embodiment, during the rotation of the roller 110, the first gear 12 and the second gear 201 also rotate in a specific direction along with the roller. When the second gear 201 rotates in a specific direction, the brush assembly 30 also rotates in a specific direction along with the second gear 201. The first gear 12 can be detachably and fixedly connected to the roller 110 to facilitate the assembly and disassembly of the roller 110.

[0103] Furthermore, in Figures 7 to 9In the illustrated embodiment, the transmission assembly 20 further includes a third gear component 302, and the brush assembly 30 includes a brush body 301 and a third gear component 302; wherein the brush body 301 and the third gear component 302 are detachably and fixedly connected, and the third gear component 302 is drively connected to the second gear component 201. The third gear component 302 also protrudes from the upper surface of the inner layer 4031 of the second side plate, and the third gear component 302 is also sealed and covered by the cofferdam and the transmission assembly cover plate 113.

[0104] In some embodiments, the brush body 301 includes a brush 3011 and a rotating shaft 3012. The third gear 302 is fixed to one end face of the rotating shaft 3012 and can be detachably fixedly connected to the rotating shaft 3012. The brush 3011 is disposed on the circumferential surface of the rotating shaft 3012. In this embodiment, the second gear 201 can be a transmission gear, and the third gear 302 can be a driven gear. That is, the second gear 201 meshes with the third gear 302. During the directional rotation of the second gear 201 with the first gear 12, the third gear 302 and the rotating shaft 3012 on the brush body 301 can also rotate synchronously, thereby enabling the brush assembly 30 to clean the roller wiping layer 111 of the roller assembly 11.

[0105] In some embodiments, such as Figures 12 to 14 As shown, the transmission assembly 20 may further include a first drive wheel 121a and a second driven wheel 302a; wherein, the first drive wheel 121a is fixedly connected to the roller component 110 via a button 1223 and is drively connected to the second driven wheel 302a; the second driven wheel 302a is fixedly connected to the brush assembly 30. The first drive wheel 121a and the second driven wheel 302a both protrude from the upper surface of the inner layer 4031 of the second side plate (the surface facing the outside of the housing body 401). The upper surface of the inner layer 4031 of the second side plate is also provided with a dam (not shown in the figure) surrounding the transmission assembly 20. A transmission assembly cover plate 113 is sealed on the dam, and the outer layer 4032 of the second side plate is sealed on the inner layer 4031 of the second side plate that is covered by the transmission assembly cover plate 113.

[0106] In this embodiment, during the rotation of the roller component 110, the first drive wheel 121a rotates in a specific direction along with the roller component. The first drive wheel 121a drives the second driven wheel 302a to rotate. When the second driven wheel 302a rotates in a specific direction, the brush assembly 30 also rotates in a specific direction along with the second driven wheel 302a. The first drive wheel 121a can be detachably and fixedly connected to the roller component 110 to facilitate the assembly and disassembly of the roller component 110.

[0107] Furthermore, such as Figures 13 to 14 As shown, the transmission assembly 20 further includes a synchronous belt (not shown) or a flexible belt (not shown), and the brush assembly 30 includes a brush body 301 and a second driven wheel 302a; wherein the brush body 301 and the second driven wheel 302a are detachably fixedly connected, and the second driven wheel 302a is drively connected to the first drive wheel 121a. When the transmission assembly 20 uses a synchronous belt, the rotation direction of the first drive wheel 121a is opposite to that of the second driven wheel 302a, which is more conducive to the brush body 301 of the brush assembly 30 performing reverse brushing on the surface of the roller 110, resulting in higher efficiency in removing solid waste. Of course, the transmission assembly 20 can also use a flexible belt. When the flexible belt winds clockwise around the first drive wheel 121a and the second driven wheel 302a, the rotation direction of the first drive wheel 121a is opposite to that of the second driven wheel 302a. When the flexible belt winds crosswise around the first drive wheel 121a and the second driven wheel 302a, the rotation direction of the first drive wheel 121a is the same as that of the second driven wheel 302a. Users can choose different winding methods of the flexible belt according to their needs. Of course, the first drive wheel 121a and the second driven wheel 302a can also be made of magnetic material. The two are not directly physically connected by any other components. They rotate in opposite directions without any physical connection, relying solely on the magnetism of their respective magnetic materials. In this way, the operating noise of the transmission assembly 20 is lower.

[0108] Furthermore, in Figure 10 , Figure 11 In the embodiment shown, the first gear component 12 includes a gear 121 and an elastic component 122; wherein the gear 121 is engaged with the elastic component 122, and the elastic component 122 is detachably and fixedly connected to the roller component 110 in the inner cavity of the roller component 110.

[0109] In this embodiment, the gear 121 in the first gear component 12 also meshes with the second gear component 201. The elastic element 122 can serve as the rotating shaft of the roller component 110. The gear 121 of the first gear component 12 can rotate in a specific direction as the roller component 110 rotates. At the same time, the elastic element 122 can be detachably and fixedly connected to the roller component 110 in the inner cavity of the roller component 110 to facilitate the assembly and disassembly of the roller component 110.

[0110] Furthermore, in Figure 10 , Figure 11In the illustrated embodiment, the elastic element 122 includes a rotating shaft 1221 and a spring 1222; wherein, a first abutment 12211 is provided on the outer side of the rotating shaft 1221, and the spring 1222 is sleeved on the rotating shaft 1221 and located on the side of the first abutment 12211 away from the gear 121; the rotating shaft 1221 is elastically abutted against the bushing 112 by the spring 1222, and the bushing 112 is detachably abutted against the roller 110 in the inner cavity of the roller 110.

[0111] In this embodiment, the rotating shaft 1221 can serve as the rotating shaft of the roller assembly 110, and can extend and retract within the inner cavity of the roller assembly 110 via the spring 1222. When the roller assembly 11 needs to be installed in the cleaning head assembly, the spring 1222 is sleeved on the rotating shaft 1221 located on the side of the first stop 1221 away from the gear 121. By applying pressure to the end face of the rotating shaft 1221 near the gear 121, the spring 1222 is compressed by the first stop 12211, and the rotating shaft 1221 moves a certain distance. At the same time, the rotating shaft 1221 is rotated by a certain angle, so that the rotating shaft 1221 abuts against the roller assembly within the inner cavity of the roller assembly 110.

[0112] In some embodiments, such as Figure 10 , Figure 11 As shown, to facilitate the assembly and disassembly of the elastic element 122 and the roller element 110, and to prevent the rotating shaft 1221 from dislodging from the roller element 110, a button 1223 is provided on the rotating shaft 1221. The button 1223 is sleeved on the side of the first abutting element 12211 near the gear 121 and abuts against the roller element 110 in the inner cavity of the roller element 110. Specifically, the button 1223 and the rotating shaft 1221 can be fixed together by screws 1226. A through hole (not shown in the figure) can be provided at both ends of the button 1223, and the screw 1226 is fixedly connected to the rotating shaft 1221 through the through hole.

[0113] In some embodiments, such as Figure 10 , Figure 11As shown, the end of the button 1223 away from the gear 121 is provided with a second abutment 12231. A first copper sleeve 1225 is provided between the gear 121 and the second abutment 12231. A second copper sleeve 1227 is provided on the side of the gear 121 away from the button 1223. The gear 121 is fixed to the button 1223 by the first copper sleeve 1225 and the second copper sleeve 1227. Specifically, the end of the second abutment 12231 near the roller 110 can directly abut against the roller 110 in the inner cavity of the roller 110, and the end of the second abutment 12231 away from the roller 110 can be used to limit the gear 121.

[0114] It is understood that the second abutment 12231 can be an annular protrusion (not shown in the figure) formed around the circumference of the button 1223. That is to say, the second abutment 12231 and the button 1223 can be integrally formed. At the same time, the annular protrusion can be formed by multiple protrusions. The structure of the second abutment 12231 can be selected according to the actual application. This embodiment does not make specific limitations.

[0115] In some embodiments, such as Figure 10 , Figure 11 As shown, a detachable cover 1224 is fitted onto one end of the rotating shaft 1221 near the gear 121, and abuts against the roller component 110 within the inner cavity of the roller component 110. Specifically, by fitting a detachable and fixed cover 1224 onto one end of the rotating shaft 1221 near the gear 121, the cover 1224 has multiple through holes (not shown in the figure) around its end face. Screws (not shown in the figure) can be used to fix the cover 1224 onto the aforementioned bushing 112 through the through holes. A spring 1222 is fitted onto the other end of the rotating shaft 1221. One end of the spring 1222 abuts against the bushing 112, and the other end of the spring 1222 abuts against the rotating shaft 1221, thereby achieving retractable elastic abutment of the entire elastic element 122 against the bushing 112.

[0116] Furthermore, a third abutment 12241 is also provided on the shaft cover 1224. The first abutment 12211 is located between the rotating shaft 1221 and the third abutment 12241. The shaft cover 1224 is sleeved on the first abutment 12211 and is located on the side of the third abutment 12241 near the gear 121.

[0117] In one embodiment, the third stop 12241 is used to limit the shaft cover 1224, and the first stop 12211, the third stop 12241 and the rotating shaft 1221 can be integrally formed.

[0118] It is understood that the first stop 12211 and the third stop 12241 can both be an annular protrusion formed around the circumference of the button 1223. That is to say, the first stop 12211, the third stop 12241 and the rotating shaft 1221 can be integrally formed. At the same time, the annular protrusion can be formed by multiple protrusions. The structure of the first stop 12211 and the third stop 12241 can be selected according to the actual application. This embodiment does not make specific limitations.

[0119] In some embodiments, the rotating shaft 1221 can be an integral three-section structure design, with the middle section of the rotating shaft 1221 being thicker and the two ends being thinner. The middle section of the rotating shaft 1221 can have two cut surfaces, and the protruding part after the cut surfaces can serve as a first abutment. The part of the middle section of the rotating shaft 1221 that has not been cut into two surfaces can form a third abutment.

[0120] Furthermore, such as Figure 10 , Figure 11 As shown, the roller assembly 11 further includes a roller wiping layer 111 and a bushing 112. The roller wiping layer 111 is sleeved on the outer wall of the roller component 110 of the roller assembly 11. The roller wiping layer 111 rotates with the roller component 110 and the two do not slide against each other. The elastic element 122 includes a rotating shaft 1221 and a spring 1222. The elastic element 122 is detachably and fixedly connected to the bushing 112 in the inner cavity of the bushing 112. The bushing 112 is detachably and fixedly connected to the roller component 110 in the inner cavity of the roller component 110.

[0121] In some embodiments, such as Figure 1 , Figure 5 , Figure 7 As shown, the floor scrubber also includes a waste collection component 70 and a scraper assembly 60. The waste collection component 70 is located behind the scraper assembly 60 and the roller assembly 11. The scraper assembly 60 is located between the brush assembly 30 and the roller assembly 11.

[0122] In some embodiments, such as Figures 5 to 8As shown, the housing body 401 also includes a squeezing strip 407 disposed on the inner side of the top of the housing body 401. A water-collecting strip 408 is also snapped onto the inner side of the top of the housing body next to the squeezing strip 407. A pressure cap 406 is also snapped onto the top of the opposite side of the squeezing strip 407 and the water-collecting strip 408 of the housing body. The pressure cap 406 includes a cover plate 4061 and a sealing eave 4062. The pressure cap 406 is integrally formed. A sealing ring (not shown in the figure) is sleeved on the sealing eave 4062. The housing 40 includes a first side plate 402, a second side plate 403, a housing body 401 connecting the first side plate 402 and the second side plate 403, a pressure cap 406 sealing the top of the housing body 401, and a water-collecting strip 408 snapped onto the inner wall of the top of the housing body 401.

[0123] In some embodiments, such as Figure 5 , Figure 6 As shown, the squeezing strip 407 and the water-collecting strip 408 both interfere with the roller wiping layer 111, forming a water trough structure (not shown in the figure). The pressure cap 406 mainly covers the roller wiping layer 111. The squeezing strip 407 interferes with the roller wiping layer 111 to squeeze out excess water from the roller wiping layer 111, preventing the garbage from being too wet and difficult to clean, and truly achieving dry and wet separation of garbage. The water-collecting strip 408 interferes with the roller wiping layer 111 to hold the sewage squeezed out by the squeezing strip 407 and guide it to the sewage channel inlet (not shown in the figure) so that it can be drawn away in time and will not flow along the arc surface of the roller wiping layer 111 to the garbage collection assembly 70 behind the roller assembly 11, further achieving dry and wet separation of garbage.

[0124] In some embodiments, such as Figure 1 , Figure 5 , Figure 9 As shown, the housing 40 also includes an integrated water tank 50. The integrated water tank 50 includes a clean water tank (not shown) located at the top of the integrated water tank and a wastewater tank (not shown) located at the bottom of the integrated water tank, separated by a partition plate (not shown in the figure) in the middle of the water tank. The clean water tank is used to provide clean water to the surface of the roller assembly 11, and the wastewater tank is used to collect wastewater flowing through the surface of the roller assembly 11. Both the clean water and wastewater flowing through the surface of the roller assembly 11 are confined within the water tank structure. One end of the water tank structure is connected to the clean water tank, and the other end is connected to the wastewater tank. Clean water starts from the clean water tank of water tank 40, flows through the clean water channel (not shown in the attached figure), and then flows through the water tank structure. The clean water seeps into the roller wiping layer 111 in the water tank structure and is squeezed out by the squeezing strip 407 into sewage under the high-speed rotation of the roller assembly 11. The sewage continues to flow through the sewage channel and is collected into the sewage tank of water tank 40, forming a water circulation structure in which clean water enters from one end of the water tank structure and sewage exits from the other end of the water tank structure.

[0125] In some embodiments, such as Figure 5 , Figure 9 As shown, the removable cover 404 includes a removable brush bottom cover 405 that snaps onto the removable cover body (not shown in the figure). The brush bottom cover 405 prevents debris from splashing when the brush assembly 30 cleans the roller wiping layer 111, and also facilitates the brush assembly 30 to throw the brushed debris along the arc surface of the brush bottom cover 405 into the debris collection assembly 70. The extended portion of the removable cover plate 404 also covers the pressure cover 406 to protect the pressure cover 406 and the roller assembly 11. When the user puts the floor scrubber back on the base after each cleaning, the cover structure of the extended portion of the removable cover plate 404 covering the surface of the roller wiping layer 111 helps to prevent the roller wiping layer 111 from drying and hardening due to moisture evaporation during long-term periods of non-use. When the user pushes the floor scrubber forward to clean the floor, the extended portion of the removable cover plate 404 can also prevent the soft roller wiping layer 111 from being scratched by obstacles during high-speed rotation when the cleaning head assembly hits an obstacle. When users need to thoroughly clean the cleaning head assembly of the floor scrubber after using it for a period of time, they can turn on the high-water rinse mode. At this time, removing the removable cover 404 allows the external rinsing water to directly spray onto the roller wiping layer 111 and the brush assembly 30. Any debris remaining in the water tank structure will be washed away by the combined action of the high-water rinsing, the squeezing strips, and the roller brushes. The flexible and convenient removable cover design improves the ease with which users can thoroughly clean the cleaning head assembly using the high-water rinse mode.

[0126] On the other hand, the specific working method of the floor scrubber provided in this application is as follows: when the floor scrubber is turned on, the motor 10 starts to work, and the water circuit and other components work simultaneously. When the motor 10 rotates, it drives the roller assembly 11 to rotate, thereby driving the brush assembly 30 to rotate through the transmission assembly 20. After the water circuit is working, clean water is delivered to the surface of the roller assembly 11 through the clean water tank (not shown in the attached drawing) and clean water pipe (not shown in the attached drawing) of the integrated water tank 50 to wet the surface of the roller assembly 11. At the same time, the roller wiping layer 111 of the roller assembly 11 rolls and cleans the ground. The scraper assembly 60 is designed to follow the roller assembly 11, and the garbage collection assembly 70 is located on the roller assembly 11. Behind the roller assembly 11 and below the brush assembly 30, when the roller wiping layer 111 of the roller assembly 11 rolls to clean the ground, the ground debris is scooped up by the shovel assembly 60. Through the gap between the shovel assembly 60 and the roller wiping layer 111 of the roller assembly 11, and through the friction of the roller wiping layer 111, the debris is carried into the debris collection assembly 70. At the same time, the brush assembly 30 contacts the roller wiping layer 111 of the roller assembly 11, and the brush assembly 30 sweeps away the debris remaining on the roller wiping layer 111 of the roller assembly 11, sweeping it into the debris collection assembly 70, thus collecting the ground debris. In addition, during the operation of the floor scrubber, clean water is continuously supplied to the surface of the roller wiping layer 111 of the roller assembly 11. The water used to clean the roller wiping layer 111 of the roller assembly 11 is wastewater. The wastewater enters the wastewater pipe (not shown in the attached drawing) through the water tank structure and is transported to the wastewater tank (not shown in the attached drawing) of the integrated water tank 50 for collection.

[0127] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
