In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] like Figure 1 As shown, this embodiment provides a drinking water system, including a water purification component 10, a boiled water making component 20 and an ice making component 30. The outlet end of the water purification component 10 is connected to the boiled water making component 20, and the water purification component 10 is used to provide pure water to the boiled water making component 20; the outlet end of the boiled water making component 20 is connected to the ice making component 30, and the boiled water making component 20 is used to prepare boiled water. The boiled water making component 20 is configured to transport boiled water to a boiled water outlet 261 in one way and to the ice making component 30 in another way; the ice making component 30 is used to make ice water and ice cubes from boiled water.

[0041] The drinking water system provided in this embodiment has a water purification component 10 that can purify externally supplied tap water to obtain pure water and convey it to the boiled water making component 20. The boiled water making component 20 uses pure water as a water source, heats it to a boiling state, and then cools it down to obtain boiled water. Boiled water is cooked water and can be used as direct drinking water. Therefore, one path of boiled water is conveyed to the boiled water outlet 261 for users to drink, and the other path is conveyed to the ice making component 30. The ice making component 30 uses boiled water as a water source, makes it into ice water and ice cubes, and delivers them through corresponding outlets for users to use. Boiled water has the characteristics of both pure water and boiled water. Therefore, the ice water and ice cubes produced by the drinking water system can meet the needs of pure water and boiled water at the same time, thereby meeting the drinking habits of users.

[0042] Specifically, Figure 2 As shown, the boiled water component 20 includes a normal temperature water tank 21, which is connected to the water purification component 10 and is used to store pure water. The water purification component 10 includes a PCB filter element 11, a booster pump 12 and an RO filter element 13 which are connected in sequence through pipelines. The PCB filter element 11 is a filter element made of a plurality of materials combined together, which can effectively remove large particles, silt, rust, scale and a few chemical substances dissolved in water. The RO filter element 13 uses a reverse osmosis membrane as the core filter medium, which can not only remove large particles, silt, rust and other impurities, but also remove chemical substances, heavy metal residues and microorganisms dissolved in water. When making pure water, the tap water provided by the external water source is extracted by the booster pump 12, and then filtered through the PCB filter element 11 and the RO filter element 13 in sequence to obtain pure water, which is stored in the normal temperature water tank 21 for use by the boiled water component 20.

[0043] Among them, a first solenoid valve 14 is arranged on the pipeline between the water purification component 10 and the external water source, which is used to control the conduction and cutoff of the tap water supply waterway. A second solenoid valve 211, a first pressure-bearing one-way valve 15 and a high-pressure switch 16 are also arranged on the pipeline between the water purification component 10 and the normal temperature water tank 21. The first solenoid valve 14 is used to control the conduction and cutoff of the pure water supply waterway, and the first pressure-bearing one-way valve 15 is used to prevent the pure water from flowing back into the water purification component 10 through the waterway. When the water in the normal temperature water tank 21 is full, the pressure is high enough. At this time, the valve of the high-pressure switch 16 is pushed by the pressure to disconnect and cut off the circuit, thereby controlling the water purification component 10 to stop automatically when it is full of water.

[0044] Furthermore, if Figure 2As shown, the normal temperature water tank 21 is connected to the upstream of the booster pump 12 through the return pipe 17, and the return pipe 17 is provided with a first drain valve 171. The RO filter element 13 is connected to the drainage pipe 18, and the drainage pipe 18 is provided with a combined flushing valve 181. The program of the drinking water system is provided with a pure water return flushing function. When the user selects this function by pressing a button, the first drain valve 171, the booster pump 12 and the combined flushing valve 181 are opened, and the pure water in the normal temperature water tank 21 is drawn by the booster pump 12 and passes through the RO filter element 13 to flush the RO filter element 13 for a period of time, and the waste water after flushing is discharged through the drainage pipe 18. Among them, a second pressure-bearing one-way valve 182 is also provided on the drainage pipe 18 to prevent the waste water from flowing back.

[0045] Furthermore, combined with Figure 2 and Figure 3 The capacity of the normal temperature water tank 21 is about 4.5L. A first UV antibacterial lamp 214 is arranged on the top of the normal temperature water tank 21. The first UV antibacterial lamp 214 can sterilize and disinfect, keep the water in the normal temperature water tank 21 healthy and clean, and reduce the bacterial growth in the normal temperature water tank 21. The opening time of the first UV antibacterial lamp 214 can be set according to actual needs.

[0046] Combination Figure 2 and Figure 3 A first liquid level detector 213 is provided in the normal temperature water tank 21 for real-time detection of the water level in the normal temperature water tank 21. The first liquid level detector 213 can be electrically connected to the controller, and the controller is used to receive the water level information of the normal temperature water tank 21 detected by the first liquid level detector 213, so as to maintain a certain water level in the normal temperature water tank 21, and avoid water shortage or overflow of the normal temperature water tank 21, which affects the use of the user. Exemplarily, when the water level detected by the first liquid level detector 213 is a high water level, the controller controls the boost pump 12, the first solenoid valve 14 and the second solenoid valve 211 to close, and stops producing pure water into the normal temperature water tank 21; when the water level detected by the first liquid level detector 213 is a low water level or the water level is not at a high water level, the controller controls the boost pump 12, the first solenoid valve 14 and the second solenoid valve 211 to open, and the water purification component 10 produces pure water into the normal temperature water tank 21, and when the water level is a low water level, stops producing boiled water into the warm water tank 22 of the boiled water making component 20.

[0047] Preferably, a first float valve 212 is further provided in the normal temperature water tank 21. The first float valve 212 is connected to the end of the pipeline between the water purification component 10 and the normal temperature water tank 21. The float of the first float valve 212 floats on the water surface. As the water level rises, the float also rises. When the water level in the normal temperature water tank 21 reaches a certain height, the float drives the first float valve 212 to close automatically, thereby automatically closing the waterway mechanically. The first float valve 212 plays a double insurance role to avoid overflow in the event of failure of the first liquid level detector 213.

[0048] like Figure 3 As shown, the boiled water making component 20 also includes a warm water tank 22, which is connected to the normal temperature water tank 21 through a pipeline. The pipeline between the normal temperature water tank 21 and the warm water tank 22 is also provided with a first water pump 23, a heating body 24 and a heat exchanger 25. The first water pump 23 is preferably a diaphragm pump. The first water pump 23 is used to pump the pure water in the normal temperature water tank 21 into the heating body 24. The heating body 24 is used to heat the pure water to a boiling state. The heat exchanger 25 is used to cool the heated water. The outlet end in the warm water tank 22 is respectively connected to the boiled water outlet 261 and the ice making component 30. When making boiled water, the pure water in the normal temperature water tank 21 is pumped by the first water pump 23, first heated to boiling state by the heating body 24 to obtain cooked water, and then cooled by heat exchanger 25 to obtain boiled water. The boiled water is finally stored in the warm water tank 22. The boiled water in the warm water tank 22 is at about 45° and can be drunk directly. Therefore, one of the boiled water in the warm water tank 22 can be directly transported to the boiled water outlet 261 for direct drinking by users, and the other is transported to the ice making component 30 to make ice water and ice cubes to meet the different drinking water needs of users.

[0049] Specifically, Figure 3As shown, the heat exchanger 25 includes a first heat exchange tube 251 and a second heat exchange tube 252 which are not connected to each other. One end of the first heat exchange tube 251 is connected to the water outlet of the first pump 23, and the other end is connected to the water inlet of the heating body 24. One end of the second heat exchange tube 252 is connected to the water outlet of the heating body 24, and the other end is connected to the warm water tank 22. When in use, the pure water in the normal temperature water tank 21 is pumped by the first pump 23, first enters the heating body 24 through the first heat exchange tube 251 for heating, and the heated pure water enters the second heat exchange tube 252. When the hot water flows through the second heat exchange tube 252, it exchanges heat with the normal temperature water in the first heat exchange tube 251 to become boiled water, and finally flows into the warm water tank 22 for storage. This arrangement is conducive to the rapid cooling of the hot water in the second heat exchange tube 252 into boiled water. In addition, after heat exchange, the temperature of the normal temperature water in the first heat exchange tube 251 can rise to a certain extent, and then it can be quickly heated to boiling state when entering the heating body 24, thereby reducing the energy consumption of the heating body 24. It should be noted that the two heat exchange tubes can be arranged in parallel or in a mutually nested form, as long as heat exchange can be achieved, and no specific limitation is made here.

[0050] Combination Figure 1 and Figure 3 The water outlet of the first heat exchange pipe 251 is connected to a first reversing valve 254 with one inlet and two outlets through a pipeline. The first outlet of the first reversing valve 254 is connected to the water inlet of the heating body 24 to supply pure water to the heating body 24. The second outlet of the first reversing valve 254 is connected to the normal temperature water tank 21. The valve core of the first reversing valve 254 moves so that the water inlet of the first reversing valve 254 can be selectively connected to one of the outlets. When the first reversing valve 254 is energized ( Figure 3 In the state shown in the figure, the water inlet is connected to the first outlet and is cut off from the second outlet. At this time, the first heat exchange tube 251 is connected to the water inlet end of the heating body 24 through the first reversing valve 254. When the first reversing valve 254 loses power, the water inlet is connected to the second outlet and is cut off from the first outlet. At this time, the first heat exchange tube 251 is connected to the normal temperature water tank 21 through the first reversing valve 254. When the user selects the cooling boiled water function by pressing the button, the first water pump 23, the first reversing valve 254 and the heating body 24 are all powered.

[0051] like Figure 3As shown, the water inlet end of the heating body 24 is connected to a second thermistor 241 for detecting the water temperature of the inlet water, and the water outlet end of the heating body 24 is connected to a third thermistor 242 for detecting the water temperature of the outlet water. The second thermistor 241 and the third thermistor 242 are both electrically connected to the controller to achieve temperature control, so that the temperature of the heated water reaches the set temperature. Optionally, a first thermistor 253 is also provided on the pipeline of the water outlet end of the second heat exchange tube 252, and the first thermistor 253 is used to detect the water temperature of the outlet water of the second heat exchange tube 252 in real time to facilitate temperature control.

[0052] In addition, if Figure 3 As shown, a flow meter 243 may be further provided on the pipeline at the water inlet end of the heating body 24 to monitor the flow entering the heating body 24 in real time, and the flow meter 243 may be electrically connected to the controller to regulate the flow entering the heating body 24. A second one-way valve 245 is also provided on the pipeline at the water inlet end of the heating body 24 to prevent liquid backflow.

[0053] Furthermore, combined with Figure 3 The second liquid level detector 221 is provided in the warm water tank 22 for real-time detection of the water level in the warm water tank 22. The second liquid level detector 221 can be electrically connected to the controller, and the controller is used to receive the water level information of the warm water tank 22 detected by the second liquid level detector 221. When the water level detected by the second liquid level detector 221 is a high water level, the controller controls the first water pump 23 to turn off and stop making boiled water into the warm water tank 22, so as to avoid overflow of the warm water tank 22 and affect the use of the user.

[0054] Preferably, if Figure 3 As shown, in order to further avoid overflow, a third liquid level detector 222 is also provided in the warm water tank 22. The third liquid level detector 222 is electrically connected to the controller. The third liquid level detector 222 and the second liquid level detector 221 act as double insurance to avoid overflow when one of the liquid level detectors fails.

[0055] It should be noted that, in order to keep the temperature, the warm water tank 22 is usually set to a closed state, such as Figure 3 As shown, the warm water tank 22 is provided with an exhaust pipe 223, which is connected to the normal temperature water tank 21. The gas in the warm water tank 22 can be discharged outward through the exhaust pipe 223 to maintain the pressure balance in the warm water tank 22, so that the warm water tank 22 can accommodate more boiled water.

[0056] Furthermore, if Figure 4As shown, the water inlet end of the warm water tank 22 and the heating body 24 are connected through the second water pump 27, and the second water pump 27 is preferably a diaphragm pump. A fourth thermistor 224 is provided in the warm water tank 22, and the fourth thermistor 224 is respectively connected to the second water pump 27 and the heating body 24 for communication. The fourth thermistor 224 is used to detect the water temperature in the warm water tank 22 in real time and is electrically connected to the controller, and the controller is used to receive the water temperature detected by the fourth thermistor 224 and control the second water pump 27 and the heating body 24 to work. When the high water level in the warm water tank 22 is reached, the temperature detected by the fourth thermistor 224 determines whether to execute the insulation cycle of the warm water tank 22 to heat up or wait for the warm water in the warm water tank 22 to cool down.

[0057] In standby mode, when the temperature detected by the fourth thermistor 224 is lower than 40°C, the controller controls the second pump 27 and the heater 24 to start, and the boiled water in the warm water tank 22 is pumped by the second pump 27, heated to boiling water by the heater 24, and then returned to the warm water tank 22 after passing through the second heat exchange tube 252, and the heating cycle is repeated until the temperature detected by the fourth thermistor 224 reaches 50°C, and the heating cycle is stopped. In this way, the boiled water in the warm water tank 22 can be kept fluctuating within the temperature range of 40°C to 50°C, and the boiled water within this temperature range can be directly drunk.

[0058] In addition, if Figure 4 As shown, an over-flow UV lamp 225 and a first one-way valve 226 are also provided on the pipeline between the warm water tank 22 and the heating body 24. The over-flow UV lamp 225 is used to sterilize the boiled water flowing through the pipeline, and the first one-way valve 226 is used to prevent the boiled water from flowing back.

[0059] Furthermore, if Figure 1 and Figure 5 As shown, the water outlet of the heating body 24 is connected to a second reversing valve 246 with one inlet and two outlets. The first outlet of the second reversing valve 246 is connected to the water inlet of the second heat exchange tube 252 to deliver hot water to the second heat exchange tube 252. The second outlet of the second reversing valve 246 is connected to the water outlet 261 of the cold water to deliver cold water to the water outlet 261. The valve core of the second reversing valve 246 moves so that the water inlet of the second reversing valve 246 can be selectively connected to one of the outlets. When the second reversing valve 246 loses power (such as Figure 3 and Figure 4 The water inlet is connected to the first outlet and is blocked from the second outlet. At this time, the water outlet of the heating body 24 is connected to the water inlet of the second heat exchange pipe 252 through the second reversing valve 246. When the second reversing valve 246 is energized ( Figure 5 In the state shown), the water inlet is connected to the second outlet and is blocked from the first outlet. At this time, the water outlet end of the heating body 24 is connected to the boiled water outlet 261 through the second reversing valve 246.

[0060] like Figure 5 As shown, when the user selects warm water or boiled water by pressing the button, the second water pump 27, the flow-through UV lamp 225, the heating body 24 and the second reversing valve 246 are all electrically started. The boiled water in the warm water tank 22 is extracted by the second water pump 27, sterilized by the flow-through UV lamp 225, heated by the heating body 24, and then flows out through the boiled water outlet 261 for the user to drink. According to the temperature selected by the user, the real-time feedback of the second thermistor 241 and the third thermistor 242 at both ends of the heating body 24 can ensure that the water outlet temperature is consistent with the selected temperature. When the user selects warm water (45°C), there is no need to start the heating body 24.

[0061] It should be noted that the heating body 24 needs to be able to adjust the power to ensure the water flow rate. The boiled water outlet 261 is specifically arranged on the water vapor separation box 26, which can remove bubbles in the hot water, thereby ensuring smooth water flow when the water is discharged, and preventing hot water from splashing and scalding the user.

[0062] Furthermore, if Figure 6 As shown, the water outlet end of the second heat exchange pipe 252 is connected to a third reversing valve 227 with one inlet and two outlets. The first outlet of the third reversing valve 227 is connected to the warm water tank 22 to deliver boiled water to the warm water tank 22. The second outlet of the third reversing valve 227 is connected to the ice-making assembly 30 to deliver boiled water in the warm water tank 22 to the ice-making assembly 30 through the second water pump 27. The valve core of the third reversing valve 227 moves so that the water inlet of the third reversing valve 227 can be selectively connected to one of the outlets. When the third reversing valve 227 loses power (such as Figure 3 and Figure 4 The water inlet is connected to the first outlet and is blocked from the second outlet. At this time, the water outlet of the second heat exchange pipe 252 is connected to the warm water tank 22 through the third reversing valve 227. When the third reversing valve 227 is energized (as shown in FIG. Figure 6 The water inlet is connected to the second outlet and is blocked from the first outlet. At this time, the water outlet end of the second heat exchange tube 252 is connected to the ice-making assembly 30 through the third reversing valve 227. The boiled water in the warm water tank 22 can flow to the ice-making assembly 30 through the heating body 24, the second heat exchange tube 252 and the third reversing valve 227 in sequence, thereby realizing automatic filling of the water tank of the ice-making assembly 30, improving the user experience. The ice water and ice cubes produced by the ice-making assembly 30 are all made of cooked water, which can meet the user's drinking habits.

[0063] Specifically, Figure 7As shown, the ice-making assembly 30 includes an ice-making water tank 31 and an ice-making module 32. The ice-making water tank 31 is connected to the second outlet of the third reversing valve 227. The ice-making water tank 31 is used to make ice water from boiled water. The outlet end of the ice-making water tank 31 is respectively connected to the ice water outlet 33 and the ice-making module 32. The ice-making module 32 is used to make ice cubes from ice water. The outlet end of the ice-making module 32 is connected to the ice outlet 34. A third solenoid valve 35 is also provided on the pipeline between the ice-making water tank 31 and the third reversing valve 227. The third solenoid valve 35 is used to control the conduction and cutoff of the boiled water supply circuit. A second drain valve 314 is also provided on the pipeline between the ice-making water tank 31 and the ice water outlet 33. The second drain valve 314 is used to control the conduction and cutoff of the ice water outlet pipeline. A fourth one-way valve 315 is also provided on the pipeline between the second drain valve 314 and the ice water outlet 33 to prevent the ice water from flowing back.

[0064] Combination Figure 6 and Figure 7 When the user selects to discharge ice water by pressing the button, the second pump 27, the flow-through UV lamp 225, the third reversing valve 227, the third solenoid valve 35 and the second drain valve 314 are all powered on. The boiled water in the warm water tank 22 is extracted by the second pump 27, sterilized by the flow-through UV lamp 225, and then flows into the ice water tank 31 through the heating body 24, the second heat exchange tube 252 and the third reversing valve 227 to make ice water (5℃~10℃). The ice water in the ice water tank 31 flows out through the ice water outlet 33 for drinking by the user. It should be noted that the ice water tank 31 is in a closed state and is not connected to the external atmosphere. Therefore, in the process of discharging ice water, the boiled water pumped into the ice water tank 31 from the warm water tank 22 continuously pushes the ice water in the ice water tank 31 to flow out through the ice water outlet 33. In this process, the heating body 24 is not started and is only used as a pipeline, so there is no need to set up a separate pipeline, thereby achieving the purpose of simplifying the pipeline.

[0065] It is understandable that, considering the high temperature of the boiled water in the warm water tank 22 (40°C to 50°C), it will affect the cooling water capacity of the whole machine. Figure 6 As shown, when the ice water discharge function is started, the first pump 23 is also started at the same time, and the first reversing valve 254 is in a power-off state at this time, that is, the water outlet end of the first heat exchange pipe 251 is connected to the normal temperature water tank 21 through the first reversing valve 254. While the ice water is discharged, the low-temperature pure water in the normal temperature water tank 21 is pumped by the first pump 23 and then returns to the normal temperature water tank 21 through the first heat exchange pipe 251, so that the low-temperature pure water in the first heat exchange pipe 251 exchanges heat with the high-temperature boiled water in the second heat exchange pipe 252, so as to reduce the temperature of boiled water entering the ice water tank 31, thereby improving the refrigeration water capacity of the whole machine.

[0066] Furthermore, if Figure 7 As shown, a second UV antibacterial lamp 313 is arranged on the top of the ice-making water tank 31. The second UV antibacterial lamp 313 can sterilize and disinfect, keep the water in the ice-making water tank 31 healthy and clean, and reduce the bacterial growth in the ice-making water tank 31. The opening time of the second UV antibacterial lamp 313 can be set according to actual needs.

[0067] like Figure 7 As shown, a fourth liquid level detector 312 is provided in the ice-making water tank 31, which is used to detect the water level in the ice-making water tank 31 in real time. The fourth liquid level detector 312 can be electrically connected to the controller, and the controller is used to receive the water level information of the ice-making water tank 31 detected by the fourth liquid level detector 312. When the water level detected by the fourth liquid level detector 312 is a high water level, the controller controls the second pump 27 and the third solenoid valve 35 to be closed to stop making ice water into the ice-making water tank 31, so as to avoid overflow of the ice-making water tank 31 and affect the use of the user.

[0068] Preferably, a second float valve 311 is further provided in the ice-making water tank 31. The second float valve 311 is connected to the end of the water supply path of the cool water. The float of the second float valve 311 floats on the water surface. As the water level rises, the float also rises. When the water level in the ice-making water tank 31 reaches a certain height, the float drives the second float valve 311 to close automatically, thereby automatically closing the water path mechanically. The second float valve 311 plays a double insurance role to avoid overflow when the fourth liquid level detector 312 fails.

[0069] Furthermore, if Figure 7 As shown, the pipeline between the ice-making water tank 31 and the ice-making module 32 is also provided with a third pump 36 and a fourth solenoid valve 37. The third pump 36 is preferably a diaphragm pump, and the fourth solenoid valve 37 is used to control the conduction and cutoff of the ice water supply water circuit. When the user selects the ice-making function by pressing a button, the third pump 36 and the fourth solenoid valve 37 are powered on, and the ice water in the ice-making water tank 31 is pumped by the third pump 36 and flows into the ice-making module 32 to make ice cubes. The pipeline between the ice-making module 32 and the ice outlet 34 is also provided with a fifth solenoid valve 321. The fifth solenoid valve 321 is used to control the conduction and cutoff of the ice-discharging pipeline. When the user selects to discharge ice cubes, the fifth solenoid valve 321 is opened, and the ice cubes are delivered from the ice outlet 34 for the user to use.

[0070] It should be noted that the ice water tank 31 and the ice cube making module 32 are both prior art, and their specific structures and the principles of making ice water and ice cubes are the same as those of refrigerators on the market, which will not be described in detail here. At the same time, the controller is also prior art, and the present application can use any controller and electrical connection method that can achieve the above functions, which will not be described in detail here.

[0071] Furthermore, combined with Figure 1 and Figure 8 The water inlet of the heating body 24 is connected to a fourth reversing valve 262 with one inlet and two outlets. The first outlet of the fourth reversing valve 262 is connected to the water inlet of the heating body 24 to supply water to the heating body 24. The second outlet of the fourth reversing valve 262 is connected to the water outlet 261 of the cold boiled water. The valve core of the fourth reversing valve 262 moves so that the water inlet of the fourth reversing valve 262 can be selectively connected to one of the outlets. When the fourth reversing valve 262 loses power (such as Figure 4 The water inlet is connected to the first outlet and is blocked from the second outlet. At this time, the water outlet of the first heat exchange tube 251 is connected to the water inlet of the heating body 24 through the fourth reversing valve 262. When the fourth reversing valve 262 is energized (as shown in FIG. Figure 8 The water inlet is connected to the second outlet and is blocked from the first outlet. At this time, the water outlet end of the first heat exchange tube 251 is connected to the boiled water outlet 261 through the fourth reversing valve 262.

[0072] Combination Figure 8 When the user selects pure water by pressing the button, the first pump 23, the first reversing valve 254 and the fourth reversing valve 262 are energized, and the room temperature pure water in the room temperature water tank 21 is pumped by the first pump 23, passes through the first heat exchange pipe 251 and flows out from the cold boiled water outlet 261 for drinking by the user. Among them, a third one-way valve 263 is also provided on the pipeline between the fourth reversing valve 262 and the cold boiled water outlet 261 to prevent the pure water from flowing back.

[0073] To sum up, the drinking water system provided in this embodiment can supply pure water at room temperature, hot water heated to the required temperature, cooled boiled water, ice water and ice cubes to the outside, so that one machine can supply different types of drinking water to meet the different drinking water needs of users and enhance the user experience.

[0074] It should be noted that, in one embodiment, the drinking water system can be set to be connected to three devices for use, that is, the water purification component 10, the cold boiled water component 20 and the ice making component 30 are respectively constructed as different devices, for example, the water purification component 10 can be a water purifier, the cold boiled water component 20 can be a water dispenser, and the ice making component 30 can be a refrigerator. In order to achieve the above functions, the three devices are connected through pipelines. In another embodiment, the water purification component 10 and the cold boiled water component 20 can be integrated into a water purifier, and the ice making component 30 can be a refrigerator, and the two devices are connected through pipelines. In another embodiment, the drinking water system can be set in one device for use, such as integrating the water purification component 10 and the cold boiled water component 20 in a refrigerator for use, and using the ice making system of the refrigerator to reduce the cost and volume of the water dispenser and the water purifier. In other embodiments, it can also be set in other forms, which can be flexibly set according to actual needs, and no specific limitation is made here.

[0075] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
