Description

Technical Field

[0001] This application relates to the field of surface cleaning apparatus technology, and in particular to a surface cleaning system. Background Technology

[0002] With the fast pace of modern life, surface cleaning equipment is widely used in people's lives. To meet customers' cleaning needs for various surfaces, surface cleaning equipment is further subdivided into different functional surface cleaning machines, such as floor scrubbers and floor cleaners that use water or cleaning solutions to clean floors (including cement floors, wooden floors, and tiles); dry vacuum cleaners for vacuuming and removing large particles of dirt; and fabric cleaning machines for cleaning sofas, mattresses, carpets, etc. Currently, the main components of existing surface cleaning machines with different functions are not universally compatible or interchangeable. This means that users need to purchase a complete set of products for each surface cleaning machine, resulting in multiple products taking up considerable space, causing waste, and increasing the user's purchase cost.

[0003] Therefore, multi-functional vacuum cleaners that can also be used for floor cleaning have appeared on the market. For example, patent application number 202011097924 X discloses a cleaning device including a floor brush, a body, and a recycling bin assembly on the floor brush or body; a power source assembly, which is detachably connected to the body and provides suction power so that airflow can at least pass through the interior of the recycling bin assembly. The technical solution provided by this invention integrates the power unit and battery into a power source assembly, which can be detached from the body. This allows the power source assembly to have a first usage mode of being installed on the cleaning device, and a second usage mode of being removed from the cleaning device and used as a standalone suction device. This improves the flexibility of the cleaning device, reduces maintenance costs, and provides a better user experience. However, this cleaning equipment only provides a shared power source component and various external accessories such as a dustbin, mite remover connector, and nozzle. These accessories are connected to the power source, but all require manual operation of the mite remover connector and nozzle to move and remove mites and vacuum, making operation still very inconvenient. For cleaning fabrics such as sofas and mattresses, a longer connector is required, as both water spraying and vacuuming are needed. Therefore, it is still necessary to drag the machine body with the recycling bin and cleaning solution tank to the item being cleaned, and manually operate the cleaning head for cleaning, which is very inconvenient. Therefore, it still cannot meet people's requirements. In addition, a large space is still needed in the bathroom to store these machines or accessories, making them inconvenient to use. Furthermore, cleaning accessories such as the recycling bin, floor brush, and dust cup after use is also a significant problem.

[0004] Furthermore, patent application number 201680065912 4 discloses an extractor (20) comprising: a housing (22); a suction source (29) disposed within the housing (22); and a suction nozzle (34) communicating with the suction source (29) and movable relative to the housing (22). The extractor (20) further includes a recovery tank (26) carried by the housing (22), and the suction source (29) is in communication with the recovery tank (26) for suctioning fluid through the suction nozzle (34) and storing the fluid extracted from the recovery tank in the recovery tank (26). A cleaning chamber (68) disposed on the housing (22) is used to accommodate a portion of the suction nozzle (34), and the cleaning chamber (68) is configured to selectively receive fluid along a fluid flow path (70) communicating with the cleaning chamber (68). Furthermore, this extractor is equipped with multiple auxiliary tools and a cleaning chamber. The auxiliary tool supply box and the recovery box are connected. Under the action of the suction source, water is sprayed to clean and the cleaned dirt is collected into the recovery box. The auxiliary tools can also be placed in the cleaning chamber. The supply box is not connected to the auxiliary tools, but is connected to the nozzle so that the nozzle sprays liquid to clean the auxiliary tools. This patent solves the problem of self-cleaning of auxiliary tools. However, this technical solution is only suitable for cleaning fabrics and does not provide a floor brush for cleaning floors or a machine body connected to the floor brush. Therefore, it still cannot solve the cleaning problems of different types of floors or fabrics. Summary of the Invention

[0005] This invention overcomes the above-mentioned technical problems and provides a multifunctional surface cleaning system with multiple cleaning components. The main accessories such as the power source component, the waste tank, and the clean water tank have a certain degree of versatility and interchangeability.

Under the action of the power source system, the dirt on the surface to be cleaned enters the container through the suction port on the cleaning head, the second dirt collection channel, and the suction pipe.

[0009] Furthermore, the main body is also equipped with a scraper and a water spray nozzle. The second water supply pipe is fixed inside the main body and connected to the water spray nozzle. The scraper is located above the suction port, and the water spray nozzle is located above the scraper. The clean water tank is removed from the housing and installed on the machine body. The other end of the second water supply pipe extends upward from the adapter cavity into the machine body and connects to the clean water tank, which facilitates the cleaning roller to clean the surface to be cleaned. At the same time, under the action of the power source component, the cleaned dirt is sucked into the dirt collection bucket.

[0010] Furthermore, a first adapter is provided on the side wall of the housing. The suction port of the first dirt collection channel and the water supply port of the first water supply pipe are both located in the first adapter. The suction hose is connected to the first adapter. The suction port and the suction hose are connected. The water supply port is connected to and communicates with the water supply hose, which facilitates the cleaning brush to clean the surface of the fabric. At the same time, under the action of the power source system, dirt enters the dirt container through the suction port, the second dirt collection channel, the first dirt collection channel, and the suction pipe.

[0011] Furthermore, the housing is also provided with an exhaust channel connected to the power source component. The exhaust outlet of the exhaust channel is provided with a second adapter. The cloth cleaning brush with a suction hose is detached from the first adapter and inserted into the second adapter, so that the suction hose is connected to the exhaust channel, and the air inside the housing is discharged from the suction port. The suction port is aimed at the cleaned object surface to dry it.

[0012] Furthermore, the suction pipe is externally placed in the sludge container, the sludge container is provided with a suction through hole, the shell and / or the sludge container is provided with a limiting groove, the suction pipe is detachably located in the limiting groove, and the suction pipe is connected to the sludge container through the suction through hole.

[0013] Furthermore, the top wall of the housing is provided with a positioning cavity, and the power source assembly is detachably installed in the positioning cavity. The side wall of the positioning cavity is also provided with wiring terminals for supplying power to the components inside the housing and electrical connectors for charging the power source assembly.

[0014] Furthermore, the housing is also provided with a third adapter, which is connected to the clean water tank through the first water supply pipe. The suction hose and cleaning brush are detached from the first adapter and connected to the third adapter to start the automatic cleaning program. The clean water tank provides cleaning fluid to automatically clean the suction hose, suction port, first dirt collection channel, suction pipe, and dirt container.

[0015] Furthermore, the base is also provided with a cleaning seat that can be pulled forward from the base. The second cleaning component is placed on the cleaning seat, and the clean water tank, power source component and sludge collection bucket are placed on the housing. When the automatic cleaning program is started, the clean water tank provides cleaning fluid to automatically clean the cleaning roller, suction pipe and second dirt collection channel.

[0016] After adopting the above technical solution, the present invention has the following advantages: By setting a first cleaning component and a second cleaning component, the power source component, the clean water tank, and the waste collection bucket are respectively assembled with the first cleaning component or the second cleaning component to form at least two cleaning devices. The first cleaning component includes a base with a housing fastened thereon and a cleaning head detachably connected to the housing. The housing is provided with a first water supply pipe and a first dirt collection channel. The waste collection bucket is provided with a vent communicating with the power source component and a suction pipe communicating with one end of the first dirt collection channel. The vent is located above the opening of the suction pipe. The cleaning head of the first cleaning component is provided with a suction port communicating with the other end of the first dirt collection channel. By installing the power source component, the waste collection bucket, and the clean water tank on the housing, the first cleaning component is assembled into a first cleaning device. Under the action of the power source component, the gas in the waste collection bucket is sucked into the power source component through the vent, creating a negative pressure in the waste collection bucket. The dirt is drawn through the suction port on the cleaning head and the first dirt collection channel. The system collects dirt and grime from the suction pipe into the sludge bin, completing the vacuuming or sludge removal function. Different cleaning heads can be replaced on the first cleaning component to achieve functions such as vacuuming or mite removal, sucking up dirt, dust, mites, etc., attached to items or floors into the sludge bin. When the water tank receives a command, it supplies water to the cleaning head of the first cleaning component or the surface to be cleaned through the first water supply module, cleaning dirty surfaces such as sofas, mattresses, and other fabric items, and sucking the cleaned dirt into the sludge bin. When the power source component and sludge bin are detached from the housing and directly installed on the second cleaning component, a second cleaning device independent of the housing can be formed for vacuuming floors, under beds, etc. Installing the water tank on this cleaning component allows it to clean floors, etc. Users only need to purchase one multi-functional surface cleaning system, using a minimal number of components to create various surface cleaning devices, saving on purchase costs. Because the vent is located above the pipe opening, the sewage in the wastewater container will not be directly sucked out by the vent before it reaches the pipe opening. The water tank of this invention is detachably mounted on the housing, and a water filling device is provided on the housing for convenient water replenishment by the user.The first cleaning component is detachably mounted on the housing and directly connected to the clean water tank. This allows for automatic cleaning of the cleaning head or cleaning of other heavily soiled parts, reducing the frequency of contact between the customer and dirty components. Furthermore, if a drain port is provided on the housing, the waste in the waste container can be automatically discharged. After discharge, the first cleaning component with the cleaning head can be connected to the clean water tank for automatic cleaning. Customers can then empty the waste into the sewer without disassembling the waste container and clean it themselves under running tap water, reducing physical labor. This multi-functional surface cleaning system, through its multi-form combination, not only achieves both wet and dry cleaning but also features a modular design that makes assembly easier, operation simpler, and allows for more cleaning functions. It is also more intelligent and user-friendly, providing a better customer experience. Attached Figure Description

The other end of the second water supply pipe 23 extends upward from the adapter cavity 572 into the machine body and communicates with the clean water tank 21, which facilitates the cleaning roller to clean the surface to be cleaned. This completes the assembly of a machine body. A surface cleaning device that can perform wet cleaning of the surface to be cleaned. When the cleaning function is activated, water in the clean water tank is pumped into the second water supply pipe 23 to provide clean water to the spray nozzle 573. The spray nozzle 573 sprays water onto the surface to be cleaned or the cleaning roller 577. The cleaning roller rotates under the action of the drive motor and cleans the surface to be cleaned. The scraper scrapes off the dirt or sludge on the bristles of the cleaning roller. Under the action of the suction motor, a negative pressure is generated in the sludge collection tank. The sludge and / or dirt enter the sludge collection tank 3 through the suction port 571, the second dirt collection channel 38, and the suction pipe 34. This process is repeated until the cleaning is completed, thus completing the cleaning function of the surface to be cleaned.

[0041] Of course, it is understandable that we can also configure the second cleaning component directly as a floor brush with a body and a second dirt collection channel and a second water supply pipe. The floor brush and the body are hinged together. The floor brush is equipped with a suction port, a water spray port and a scraper. The water tank, the dirt container and the power source component are removed from the housing and installed on the body to assemble a surface cleaning device that can perform wet cleaning. Such a surface cleaning device is equipped with multiple functions such as vacuuming and cleaning. When performing the vacuuming function, the scraper is set to be floating or detachable. At this time, the scraper is removed or the scraper is moved up and separated from the cleaning roller, so that the water pump does not operate and the water spray port does not spray water. Instead, the vacuum motor is started. Under the action of the vacuum motor, a negative pressure is generated in the dirt container. The dirt and / or debris enter the dirt container 31 through the suction port 571, the second dirt collection channel 38 and the suction pipe 34 to complete the vacuuming work.

[0042] In this embodiment, the base 1 is also provided with a cleaning seat 6 that can be pulled forward from the base 1. The second cleaning device is placed on the cleaning seat 6, the automatic cleaning program is started, the clean water tank 21 provides cleaning liquid, and the water spray nozzle on the floor brush sprays water into the cleaning seat or the cleaning roller to automatically clean the cleaning roller, the suction pipe and the second dirt collection channel 38.

[0043] In this embodiment, a second adapter 18 is provided around the exhaust outlet 131 of the exhaust channel 13. The fabric cleaning brush with a suction hose 54 is detached from the first adapter 17 and inserted into the second adapter 18, so that the suction hose 54 is connected to the exhaust channel 13, and the air inside the housing 11 is discharged from the suction port 511. The suction port 511 of the fabric cleaning brush is aligned with the cleaned object surface to air dry it. Of course, it can also be understood that the fabric cleaning brush can be aligned with the floor brush placed on the base to air dry the cleaned cleaning roller and the second dirt collection channel inside the floor brush, or aligned with the first dirt collection channel and the dirt container inside the housing to air dry these parts, ensuring that these cleaned parts dry quickly and avoiding dampness and mold.

[0044] In this embodiment, the side wall of the positioning cavity 12 is also provided with wiring terminals for supplying power to the components inside the housing 11 and electrical connectors for charging the power source assembly 4. For example... Figure 8 As shown, the technical solution enables electrical connection between the power source assembly 4 and the base 1 when the power source assembly 4 is installed in the positioning cavity 12. The power source assembly 4 can be charged, and the electrical components on the housing 1 can be controlled via buttons on the power source assembly 4.

[0045] The bottom of the base 1 is also provided with a cleaning seat 113 that can be pulled forward from the base 1. The second cleaning component 50, which has a cleaning roller 577 and a body 53, is placed on the cleaning seat 113. When the automatic cleaning program is started, the clean water tank 21 provides cleaning solution to automatically clean the cleaning roller 577, the suction pipe 34, and the second dirt collection channel 38. The cleaning seat 113 can be used to place the second cleaning component 50. After the cleaning roller on the second cleaning component is cleaned, the cleaning seat 113 can be directly pulled out for separate cleaning.

[0046] In this embodiment, the housing 11 is further provided with a docking part 114 that mates with the body 53. The docking part 114 is provided with electrical contacts. When the floor brush with cleaning roller 577 and the second cleaning component 50 of the body, together with the sludge bucket, clean water tank and power source component, form a wet surface cleaning device, and the surface cleaning device is placed on the cleaning seat 113, the body 53 mates with the docking part 114, and the electrical contacts on the body 53 are electrically connected to the electrical contacts on the docking part 114. When the body 53 mates with the docking part 114, the power source component 4 installed on the body 53 can be charged through the docking part 114 on the housing 11. When the power source component 4 is installed separately on the housing 11, it can also be charged separately through the electrical connector 9 provided on the housing 11.

[0047] Of course, it is understandable that a third adapter (not shown in the figure) can also be provided on the housing 11. The third adapter is connected to the clean water tank through the first water supply pipe. The suction hose and the fabric cleaning brush are removed from the first adapter and connected to the third adapter. The automatic cleaning program is started, and the clean water tank provides cleaning fluid to automatically clean the suction hose, the first dirt collection channel, and the suction port on the fabric cleaning brush.

[0048] Of course, it is understandable that the suction pipe can also be set on the bottom wall inside the sludge container, and the vent of the sludge container can be set on and extend upward from the bottom wall of the sludge container; the suction pipe can also be integrally formed with the sludge container, as long as the opening of the suction pipe is set lower than the vent and the two are staggered, so that the sewage sprayed from the opening of the suction pipe is far away from the vent, avoiding the sewage from entering the suction motor of the power source component from the vent and air inlet, thus affecting the operation of the suction motor. Such technical solutions that do not depart from the concept of the present invention are also within the protection scope of the present invention, and will not be listed one by one here.

[0049] Of course, it is understandable that we could also provide a third cleaning component, which includes a dust cup with a long and large suction port (i.e., a long flat suction nozzle). A handle is provided on the housing of the power source component, allowing the power source component to be detached from the housing and installed onto the dust cup to assemble a handheld vacuum cleaner for vacuuming. A cleaning head for a mite remover can also be connected to the dust cup for mite removal. Alternatively, a fourth cleaning component could be provided, comprising a dust cup and a body with a floor brush. The body has a suction channel, and the power source component is sequentially installed onto the body with the floor brush, allowing it to be assembled into a standalone vacuum cleaner. Such technical solutions that do not depart from the concept of this invention are also within the scope of protection of this invention, and will not be listed in detail here.

[0050] Example 2:

[0051] Compared with Embodiment 1, the structure of the base and housing of the first cleaning component is different, and the structure of the first cleaning device assembled from the sludge bucket, the clean water tank and the power source component is also different.

[0052] As described in this invention, the multifunctional surface cleaning system that can be used both wet and dry is as follows: Figure 12 and Figure 13As shown, the system includes a water supply module 2, a dirt collection module 3, a power source assembly 4 mounted on the housing, a water inlet tank 21, a dirt collection tank 31, a first cleaning assembly 5, and a second cleaning assembly 50. In this embodiment, the first cleaning assembly 5 includes a housing 11 and a base 1, which are fastened together to form a receiving space. The rear top of the housing 11 has an upward-facing first protrusion 117. Two forward-protruding protrusions 118 are provided on the front side of the first protrusion 117 to form a U-shaped positioning cavity 12. The housing 11 located in the U-shaped positioning cavity 12 protrudes upward and forward to form a positioning platform 119. The first protrusion 117 and the positioning platform 119 are connected and communicate with each other. An air intake 116 is provided on the front wall of the first protrusion 117, and the corresponding position on the side wall of the dirt collection tank 31 is... A vent (not shown in the figure) is provided that communicates with and is sealed to the air intake 116. An air inlet port 331 is provided at the bottom of the positioning platform 119. An air intake channel (not shown in the figure) is provided in the accommodating space. One end of the air intake channel is connected to the air intake port 331, and the other end of the air intake channel is connected to the air intake 116. The power source assembly 4 is mounted on the positioning platform 119 and is surrounded and limited by the U-shaped positioning cavity 12. The air inlet (not shown in the figure) on the outer shell 41 of the power source assembly 4 is connected with and sealed to the air intake port 331. In this embodiment, the sewage suction pipe 34 is provided outside the sewage container 31 and extends upward from the bottom of the sewage container. The vent is provided on the rear side wall of the sewage container. The vent is located at the upper end of the sewage container and is higher than the inlet of the sewage suction pipe 34 and offset from it. The exhaust inlet 132 of the exhaust channel is located on the bottom wall of the U-shaped positioning cavity 12. The exhaust channel (not shown in the figure) is located inside the first protrusion 117 and the positioning platform 119. One end of the exhaust channel is connected and sealed to the air outlet through the exhaust inlet. The exhaust channel extends from the positioning platform 119 to the rear wall of the first protrusion 117, which is the rear wall of the housing 11. The rear wall of the housing 11 is provided with an exhaust outlet 131 to discharge air out of the housing 11. The sludge bucket is installed on one side of the U-shaped positioning cavity. The housing is provided with a sludge inlet 16. The receiving space is provided with a first sludge collection channel 32. One end of the sludge inlet 16 is connected to the first sludge collection channel 32. The other end of the first sludge collection channel 16 extends from the receiving space to the front wall of the housing 11. The front wall of the housing 11 is provided with a first adapter 17. The sludge suction port 321 of the first sludge collection channel 32 is located inside the first adapter 17.The purified water tank 21 is installed on the other side of the U-shaped positioning cavity 12. An inlet 115 is provided on the housing, communicating with the purified water tank 21. A one-way valve is installed between the inlet 115 and the outlet of the purified water tank 21 to control the discharge of water from the purified water tank. A first water supply pipeline 22 is installed within the accommodating space. One end of the first water supply pipeline 22 is connected to the inlet 115, and the other end extends towards the front wall of the housing 11 within the accommodating space. The water supply port 221 of the first water supply pipeline 22 is located within the first adapter 17. The cleaning seat and the base form an integral structure. Thus, the first cleaning component, the waste container, the purified water tank, and the power source component are assembled into a first cleaning device, namely a fabric cleaning machine with a cleaning seat.

[0053] In this embodiment, the air inlet and air outlet of the power source component are both located on the bottom wall of the housing, with the air inlet located at the center and the air outlet located around the air inlet. An air inlet 110 is located on the bottom wall of the positioning cavity 12, communicating and sealingly connecting with the air inlet. Two isolation rings 19 are provided on the bottom wall of the positioning cavity 12. The air inlet 110 is located within the first isolation ring 19, while the exhaust inlet 132 of the exhaust channel is located between the first and second isolation rings. The air intake channel is connected to the air intake port 42 via the air intake port 110. The power source component 4 is inserted into the positioning cavity 12. The air intake port is inserted into the first isolation ring 19, and the air outlet is inserted between the first isolation ring 19 and the second isolation ring 19, so that the air intake port 110 and the air intake port are sealed and connected. The exhaust inlet 132 of the exhaust channel is sealed and connected to the air outlet, thereby isolating the air intake and exhaust ports of the power source component and forming a sealed and separated air intake chamber and exhaust chamber. This scheme can form a sealed and separated air intake chamber and exhaust chamber, so that the air intake path and the exhaust path are separated and do not affect each other. The power source component draws the air out of the sludge container through the air intake chamber, thereby creating a negative pressure in the sludge container, thus completing the sludge suction or dust suction.

[0054] In this embodiment, the suction pipe 34 is detachably disposed on the front side of the sludge container 31. The sludge container 31 is provided with an opening 312. The front side of the sludge container 31 is provided with a first limiting groove 313, which extends from the bottom of the sludge container 31 to the opening 312. The suction pipe 34 includes a vertical section 341 and a horizontal section 342 connected thereto. The pipe opening is disposed at the end of the horizontal section. A positioning groove (not shown in the figure) is provided at the opening. The vertical section is inserted into the first limiting groove, and the pipe opening 36 is inserted into the positioning groove. A sealing ring (not shown in the figure) is provided between the pipe opening and the positioning groove, so that the suction pipe and the sludge container are sealed and connected. The air intake 116 is disposed on the front side wall of the first protrusion 117, and the air vent (not shown in the figure) is disposed on the rear side wall of the sludge container 31. The air vent and the air intake 116 are sealed and connected. The front side of the housing is provided with a forward-extending cleaning seat. A through hole (not shown in the figure) is provided on the housing 11. The inlet 16 of the first dirt collection channel 32 extends upward through the through hole. The lower end of the suction pipe 34 is inserted into the inlet 16 of the first dirt collection channel. The suction port 321 of the other end of the first dirt collection channel 32 extends forward from the housing and passes through the cleaning seat 113 to the side wall of the cleaning seat 113. The first adapter 17 is provided on the side wall of the cleaning seat. The suction port 321 of the first dirt collection channel 32 is located in the first adapter 17.

[0055] To make the detailed structure of cleaning component 5 more clearly visible, the cleaning head of cleaning component 5 has been enlarged proportionally, such as... Figure 13 As shown, the shape of the fabric cleaning head, the arrangement of the bristles, and the position of the suction port 511 in this embodiment are different from those in Embodiment 1. The second cleaning component and the second cleaning device assembled from it in this embodiment have the same structure as those in Embodiment 1, and will not be described in detail here.

[0056] The remaining structures and beneficial effects in this embodiment are the same as in Embodiment 1, and will not be repeated here.

[0057] Example 3:

[0058] The difference between this embodiment and Embodiment 2 is the positioning structure of the suction pipe and the waste collection bucket.

[0059] As described in this invention, the multifunctional surface cleaning system that can be used both wet and dry is as follows: Figure 14As shown, the housing 11 is also provided with a placement groove 10 for placing the sludge bucket 31, which positions and limits the sludge bucket 31. The rear side wall of the sludge bucket 31 is provided with a first limiting groove (not shown in the figure). The front side wall of the first protrusion 117 of the housing 11 is provided with a second limiting groove 101. The inlet 16 of the first dirt collection channel 32 extends upward from the through hole on the housing 11 and extends into the second limiting groove 101. The suction pipe 34 is placed in the second limiting groove 101. The lower end of the suction pipe 34 is sealed and connected to the inlet 16 of the first dirt collection channel 32 provided on the housing 11. After the sludge bucket 31 is installed, the first limiting groove and the second limiting groove 101 cover the suction pipe 34, thereby fixing the suction pipe 34 to the housing. The air intake 116 is located above the second limiting groove 101. The suction pipe 34 is detachably set in the first limiting groove and the second limiting groove 101. In the above technical solution, the suction pipe 34 is set on the outer wall of the sludge container 31, which facilitates the disassembly, assembly, and positioning of the suction pipe 34.

[0060] Of course, it is understandable that the port of the first dirt collection channel can also be made not to extend from the housing, but to have a through hole on the housing for inserting the suction pipe, with a surrounding edge extending outwards from the housing around the through hole. The first dirt collection channel fits onto the surrounding edge of the through hole, and the suction pipe extends downwards along the second limiting groove to the first dirt collection channel. The suction pipe is then inserted through the through hole into the surrounding edge and sealed and connected to the first dirt collection channel. Alternatively, a clean water tank placement groove can be provided on the housing to position and limit the clean water tank; the suction pipe can also be placed inside the waste container, extending upwards from the bottom wall of the waste container, thus eliminating the need for the limiting groove for the suction pipe; the suction pipe can also be fixed to the outside of the waste container. Such technical solutions that do not depart from the concept of this invention are also within the protection scope of this invention, and will not be listed in detail here.

[0061] The remaining structures and beneficial effects in this embodiment are the same as in Embodiment 2, and will not be described in detail here.

[0062] In addition to the preferred embodiments described above, there are other embodiments of the present invention. Those skilled in the art can make various changes and modifications based on the present invention, and can also combine the above embodiments. As long as they do not depart from the spirit of the present invention, they should all fall within the scope defined in the claims of the present invention.
