Description

Technical Field

[0001] This invention relates to the field of circulating water cooling, and in particular to a combined X-ray source assembly with a circulating water cooling system. Background Technology

[0002] Currently, the known structure of an X-ray generator consists of an operating controller, a high-voltage transformer, high-voltage cables, and an X-ray tube assembly. When the generator is connected to a power source, the operating controller sets the high voltage required to generate X-rays and the heating current required for the thermionic electrons emitted by the X-ray tube cathode. Under the control of the operating controller, the high-voltage transformer generates a DC high voltage, which is applied to the cathode and anode of the X-ray tube through the high-voltage cables, thereby generating X-rays.

[0003] However, with the widespread application of X-rays in industries such as industrial applications and security inspections, there is an increasing demand for miniaturization and portability of X-ray generators. Conventional split-type X-ray generators are too large, making it difficult to implement mobile X-ray machines. Modular X-ray source assemblies offer a better solution. Modular high-frequency, high-voltage X-ray generators are widely used X-ray generating devices on the market, playing a crucial role in mobile C-arm X-ray machines, mobile radiographic X-ray machines, extracorporeal shock wave lithotripsy positioning systems, CBCT, and other applications.

[0004] Because a combined X-ray source assembly (combined X-ray head) integrates the high-voltage generator necessary for X-ray production with the X-ray tube into a sealed container, 99.5% of the electrical energy transmitted to the combined X-ray source assembly during X-ray generation is converted into heat energy. However, due to size limitations, the combined X-ray head has a limited maximum heat capacity and can absorb very limited amounts of heat energy. In scenarios such as medical imaging and industrial inspection, where high continuous output power is required, combined X-ray heads operating in traditional modes are prone to performance degradation and even malfunctions due to heat accumulation, severely affecting equipment stability and efficiency, and failing to meet the demands of long-term operation and high power output. Utility Model Content

[0005] In order to improve the heat dissipation efficiency of the combined X-ray source and meet the requirements of long-term operation and high power output of the equipment, this application provides a combined X-ray source assembly with a circulating water cooling system.

[0006] This application provides a combined X-ray source assembly with a circulating water cooling system, employing the following technical solution: A combined X-ray source assembly with a circulating water cooling system includes a combined head unit containing a high-voltage generator and an external heat dissipation device. The combined head unit contains cooling copper pipes and two cooling connectors, with both ends of the cooling copper pipes connected to the two connectors respectively. The external heat dissipation device includes a cooling circulation controller, a heat exchanger, a cooling pump, and a water tank. The water tank holds the coolant. The input end of the heat exchanger is connected to one of the cooling connectors, and the output end is connected to the water tank. The cooling pump delivers the coolant from the water tank to the other cooling connector. Both the cooling pump and the heat exchanger are electrically connected to the cooling circulation controller.

[0007] By adopting the above technical solution, when the combined compressor head is working for a long time, the coolant is delivered to a cooling connector by a cooling pump, so that the coolant is sent into the cooling copper pipe. The cooling copper pipe works with the cooling copper pipe to achieve rapid cooling of the combined compressor head through heat conduction. The cooled coolant is then sent to a heat exchanger through another cooling connector. After heat exchange, the coolant is sent to a water tank, thus ensuring the cooling performance of the coolant. The external heat dissipation device, which is set on the outside, works with the cooling copper pipe set inside the combined compressor head to achieve rapid and stable cooling of the combined compressor head. This helps to improve the heat dissipation efficiency of the compressor head, meet the requirements of long-term operation and high power output of the combined compressor head, and the external heat dissipation device occupies little space inside the combined compressor head and will not interfere with the integrated structure of the combined compressor head, thus ensuring the stability of the combined compressor head in use.

[0008] Optionally, the combined generator head is equipped with a generator head temperature sensor and a temperature switch. The generator head temperature sensor is used to detect the temperature of the combined generator head, and the temperature switch is used to control the opening and closing of the high-voltage generator. The high-voltage generator, the generator head temperature sensor, and the temperature switch are all electrically connected to the cooling circulation controller.

[0009] By adopting the above technical solution, when the temperature inside the combined generator head is higher than the threshold, i.e., the preset minimum temperature, the cooling pump starts to work, which helps to avoid the external cooling device from working ineffectively under low temperature conditions. At the same time, when the temperature inside the combined generator head exceeds the preset maximum temperature, i.e., when the internal temperature of the combined generator head exceeds the maximum allowable value, the temperature switch is turned off, thereby stopping the high voltage generator from working and facilitating the circuit breaker protection of the combined generator head.

[0010] Optionally, the output end of the heat pump is equipped with a flow rate sensor, which is electrically connected to the heat pump and the cooling circulation controller. The flow rate sensor is used to detect the flow rate of the coolant. When the coolant flow rate exceeds a preset value, the heat pump is powered on; when the coolant flow rate is less than the preset value, the heat pump is powered off.

[0011] By adopting the above technical solution, when the coolant in the pipe is blocked or the radiator pump stops due to failure, the flow rate sensor turns on, thereby cutting off the power to the radiator pump. This prevents the radiator pump from continuing to receive power due to coolant blockage or pump stoppage, which could cause long-term overload and burnout. This helps to ensure the overall operational stability of the external heat dissipation device.

[0012] Optionally, the external heat dissipation device further includes a cooling fan and a fan controller. The cooling fan is used to cool the heat exchanger, and both the cooling fan and the fan controller are electrically connected to the cooling cycle controller.

[0013] By adopting the above technical solution, the cooling fan's function of cooling the heat exchanger helps to further ensure the cooling effect of the heat exchanger on the coolant and ensure the heat dissipation stability of the heat dissipation device.

[0014] Optionally, the external heat dissipation device further includes two coolant temperature sensors, both of which are used to detect the coolant temperature output by the heat exchanger. Both coolant temperature sensors are electrically connected to the fan controller and the cooling cycle controller. The higher the temperature detected by the coolant temperature sensor, the higher the speed of the cooling fan.

[0015] By adopting the above technical solution, the cooling fan can be adjusted adaptively according to the different temperatures of the coolant, effectively avoiding energy waste caused by the cooling fan always running at high speed.

[0016] Optionally, the cooling copper pipe includes multiple vertical sections and bent sections, with each end of the bent section connected to two adjacent vertical sections.

[0017] By adopting the above technical solution, the combination of multiple bending sections and vertical sections enables the cooling copper pipe to be set as a single-channel serpentine cooling circulation loop within the combined head, which facilitates a longer flow path for the cooling copper pipe within the combined head and helps to further ensure the cooling effect of the combined head.

[0018] Optionally, the combined machine head is provided with a positioning component for positioning the vertical section. The positioning component includes a positioning fixing part, an elastic positioning part, and a positioning connecting part. The positioning fixing part and the positioning connecting part are both fixedly installed on the inner wall of the combined machine head and are respectively located on both sides of one of the vertical sections. The elastic positioning part is rotatably installed on the positioning fixing part. The positioning connecting part has a positioning groove that corresponds to and engages with the elastic positioning part. A heat-conducting pad is fixedly connected to the elastic positioning part. When the elastic positioning part is engaged in the positioning groove, the heat-conducting pad presses against the vertical section.

[0019] By adopting the above technical solution, the elastic locking part plays a role in further limiting the position of the vertical section, which helps to further ensure the stability of the position of the cooling copper pipe and facilitates the cooling copper pipe to cool the combined machine head more stably. At the same time, the setting of the heat-conducting pad also helps to ensure the performance of the cooling copper pipe while limiting its position.

[0020] Optionally, the locking connection includes a first connection, a second connection, a connecting spring, and a connecting adjustment block. The first connection is fixedly installed on the inner wall of the combined machine head. The second connection passes through and slides into the first connection. The connecting spring is disposed in the first connection and applies a spring force to the second connection to move away from the first connection. The locking groove is formed in the second connection. The connecting adjustment block passes through and slides into the first connection. The connecting adjustment block is rotatably mounted with an adjusting screw. The adjusting screw passes through and is threaded into the first connection. The connecting adjustment block has an adjusting inclined surface. The second connection has an adjusting hole. The adjusting inclined surface abuts against the hole wall of the adjusting hole near the combined machine head.

[0021] By adopting the above technical solution, when the adjusting screw is turned, the connecting adjusting block moves toward the direction of the driving adjusting inclined surface toward or away from the second connecting part, thereby facilitating the fine adjustment of the position of the second connecting part and the fixing of the elastic locking part with the locking connecting part at different positions. This facilitates the adaptation to cooling copper tubes of different sizes or the adjustment of the pressure on the same cooling copper tube, making it highly applicable.

[0022] Optionally, the two cooling connectors are connected to the heat pump and the heat exchanger respectively via two flexible hoses. Each cooling connector includes a cooling fixing head and a cooling fixing component. The cooling fixing head is fixedly installed on the combined machine head and has a cooling channel through which it runs along its own axis. The cooling fixing component is fixedly installed in the cooling channel. A connecting connector is provided at one end of the flexible hose near the cooling connector. The connecting connector includes a connecting fixing head, a connecting fixing component, a connecting cooling spring, and a connecting stop. The connecting fixing head is fixedly installed at one end of the flexible hose. The connecting fixing head has a cooling channel through which it runs along its own axis and communicates with the flexible hose. The connecting fixing component is fixedly installed in the cooling channel. The connecting cooling spring is installed on the connecting fixing component and applies a spring force to the connecting stop to move away from the connecting fixing component. The connecting stop corresponds to the cooling fixing component and blocks the opening of one end of the cooling channel. The cooling connector is provided with a fixing component for fixing the connecting connector.

[0023] By adopting the above technical solution, when the connecting joint and the cooling joint are connected, the cooling fixing component presses against the connecting baffle, causing the connecting baffle to move towards the connecting fixing component, thereby connecting the first cooling channel and the second cooling channel; the end of the connecting joint is always blocked by the spring force of the connecting cooling spring, so that the coolant in the hose is not easy to leak out when connected, which facilitates a stable connection between the hose and the cooling joint.

[0024] Optionally, the fixing component includes a fixing spring, a fixing sleeve, and a fixing ball. The outer peripheral surface of the cooling fixing head has a through-hole fixing receiving groove for accommodating the fixing ball. The outer peripheral surface of the connecting fixing head has a ball retaining groove corresponding to the fixing receiving groove and engaging with the ball. The fixing sleeve is fitted and slidably fitted onto the cooling fixing head. The fixing spring applies a spring force to the fixing sleeve in the direction of the fixing ball.

[0025] By adopting the above technical solution, the movable fixed sliding sleeve contacts the fixed ball. When the fixed ball passes into the ball slot, the fixed sliding sleeve is released. Under the elastic force of the fixed spring, the fixed sliding sleeve stably limits the position of the fixed ball, thereby realizing the connection between the cooling joint and the connecting joint in a convenient and quick manner.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The external heat dissipation device, combined with the cooling copper pipes inside the combined head, facilitates rapid and stable cooling of the combined head, which helps improve the heat dissipation efficiency of the head and meets the requirements of long-term operation and high power output of the combined head.

[0027] 2. When the coolant in the pipe is blocked, or the radiator pump stops due to malfunction, the flow rate sensor turns on, thereby cutting off the power to the radiator pump. This prevents the radiator pump from continuing to receive power due to coolant blockage or pump stoppage, which could cause long-term overload and burnout. This helps to ensure the overall operational stability of the external heat dissipation device.

[0028] 3. The combination of multiple bends and vertical sections allows the cooling copper pipes to be arranged in a single-channel serpentine cooling circulation loop within the combined head, which facilitates a longer flow path for the cooling copper pipes within the combined head and helps to further ensure the cooling effect of the combined head.

[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0036] This application discloses a combined X-ray source assembly with a circulating water cooling system.

[0037] Example 1.

[0038] Reference Figure 1 and Figure 2A combined X-ray source assembly with a circulating water cooling system includes a combined machine head 1 and an external heat dissipation device 2. The combined machine head 1 is equipped with a high-voltage generating device 3, which has an X-ray tube 301 for generating X-rays. The combined machine head 1 is also equipped with a cooling copper pipe 4. Specifically, the cooling copper pipe 4 is installed on the inner wall of the combined machine head 1. The cooling copper pipe 4 includes multiple vertical sections 401, horizontal sections 402, and bent sections 403 integrally formed. The two ends of each bent section 403 are located between two adjacent vertical sections 401 and are connected to the two adjacent vertical sections 401, so that the two adjacent vertical sections 401 are U-shaped. The connection between the horizontal section 402 and the vertical section 401 is L-shaped, so that the cooling copper pipe 4 is set as a single-channel serpentine cooling circulation loop layout in the combined machine head 1, which facilitates a longer flow path for the cooling copper pipe 4 in the combined machine head 1.

[0039] The top of the combined cooling head 1 is provided with two cooling connectors 5. In this embodiment, the two ends of the cooling copper pipe 4 are respectively welded to the two cooling heads and connected to the two cooling connectors 5, so as to deliver coolant into the cooling copper pipe 4 and discharge coolant from the combined cooling head 1 through the two cooling connectors 5. A circuit board 101 is also installed on the top of the combined cooling head 1 to facilitate electrical connection with the external heat dissipation device 2.

[0040] Continue to refer to Figure 1 and Figure 2 The external heat dissipation device 2 includes a cooling circulation controller 201, a heat exchanger 202, a heat pump 203, and a water tank 204. The water tank 204 is used to contain the coolant. The input end of the heat exchanger 202 is connected to one of the cooling connectors 5 through a hose, and the output end of the heat exchanger 202 is connected to the water tank 204 through a hose. The heat pump 203 is used to transport the coolant in the water tank 204 to another cooling connector 5 through a hose, so as to realize the circulation of coolant in the cooling copper pipe 4.

[0041] Both the heat pump 203 and the heat exchanger 202 are electrically connected to the cooling cycle controller 201, so that the start and stop of the heat pump 203 and the heat exchanger 202 can be controlled by the cooling cycle controller 201. In this embodiment, the heat exchanger 202 is selected as a finned radiator to facilitate stable recooling of the return coolant.

[0042] Continue to refer to Figure 1 and Figure 2The combined compressor head 1 is equipped with a compressor head temperature sensor 6 and a temperature switch 7. The compressor head temperature sensor 6 is used to detect the temperature of the combined compressor head 1, and the temperature switch 7 is used to control the opening and closing of the high-voltage generator 3. The high-voltage generator 3, the compressor head temperature sensor 6, and the temperature switch 7 are all electrically connected to the cooling circulation controller 201. When the temperature inside the combined compressor head 1 is higher than the threshold, i.e., the preset minimum temperature, the cooling pump 203 starts working, thereby preventing the external cooling device 2 from working ineffectively under low temperature conditions. At the same time, when the temperature inside the combined compressor head 1 exceeds the preset maximum temperature, i.e., the internal temperature of the combined compressor head 1 exceeds the maximum allowable value, the temperature switch 7 is opened, thereby stopping the high-voltage generator 3 from working, that is, realizing the circuit breaker protection of the combined compressor head 1.

[0043] Reference Figure 1 To prevent the radiator pump 203 from continuing to be powered due to coolant blockage or pump stoppage, causing long-term overload and burnout, a flow rate sensor 8 is installed at the output end of the radiator pump 203 to detect the flow rate of the coolant. The flow rate sensor 8 is electrically connected to the radiator pump 203 and the cooling circulation controller 201. When the coolant flow rate exceeds the preset value, the radiator pump 203 is powered on; when the coolant flow rate is less than the preset value, i.e., when the coolant is blocked in the pipe, the radiator pump 203 is powered off.

[0044] In addition, continue to refer to Figure 1 The external heat dissipation device 2 also includes a cooling fan 205, a fan controller 206, and two coolant temperature sensors 207. The cooling fan 205 is used to cool the heat exchanger 202. Specifically, in this embodiment, the cooling fan 205 is used to blow air onto the heat exchanger 202 to cool it down, so as to further ensure the cooling effect of the heat exchanger 202 on the coolant. The cooling fan 205 and the fan controller 206 are both electrically connected to the cooling cycle controller 201.

[0045] Both coolant temperature sensors 207 are used to detect the coolant temperature output by the heat exchanger 202. Both coolant temperature sensors 207 are electrically connected to the fan controller 206 and the cooling cycle controller 201. When the average temperature detected by the two coolant temperature sensors 207 is higher, the speed of the cooling fan 205 is higher, which facilitates the adaptive adjustment of the cooling fan 205 and effectively avoids the energy waste caused by the cooling fan 205 always running at high speed. In addition, when one coolant temperature sensor 207 fails, the other can serve as a backup to ensure the system continues to operate, thus improving reliability.

[0046] The implementation principle of Example 1 is as follows: When the combined compressor head 1 is working for a long time, the cooling pump 203 delivers coolant through a hose to one of the cooling connectors 5, thereby sending the coolant into the cooling copper pipe 4. The cooling copper pipe 4 works together to achieve rapid cooling of the combined compressor head 1 through heat conduction. The cooled coolant is then sent to the heat exchanger 202 through the other cooling connector 5. After heat exchange, the heat exchanger 202 sends the coolant to the water tank 204, thus ensuring the cooling performance of the coolant. The external heat dissipation device 2, which is set on the outside, works in conjunction with the cooling copper pipe 4 set inside the combined compressor head 1 to achieve rapid and stable cooling of the combined compressor head 1, which is beneficial to improving the heat dissipation efficiency of the compressor head and meeting the requirements of long-term operation and high power output of the combined compressor head 1. Moreover, the external heat dissipation device 2 occupies less space inside the combined compressor head 1 and will not interfere with the integrated structure of the combined compressor head 1, thus ensuring the stability of the combined compressor head 1 in use.

[0047] Example 2.

[0048] Reference Figure 3 The difference between this embodiment and embodiment 1 is that the combined head 1 is also provided with a positioning component for positioning the vertical section 401, so as to further ensure the stability of the position of the cooling copper pipe 4. In this embodiment, the number of vertical sections 401 is set to eight, and four sets of positioning components are provided and are corresponding to four of the vertical sections 401.

[0049] Reference Figure 3 and Figure 4 The positioning assembly includes a positioning fixing part 9, an elastic positioning part 10, and a positioning connecting part 11. The positioning fixing part 9 and the positioning connecting part 11 are both fixedly installed on the inner wall of the combined machine head 1 and are located on both sides of the vertical section 401 in the horizontal direction. The elastic positioning part 10 is rotatably installed on the positioning fixing part 9. The positioning connecting part 11 has a positioning groove 12 that corresponds to and engages with the elastic positioning part 10. A heat-conducting pad 13 is fixedly connected to one side of the elastic positioning part 10. When the elastic positioning part 10 is engaged in the positioning groove 12, the heat-conducting pad 13 presses against the vertical section 401 to limit the position of the vertical section 401 and ensure the stability of the position of the cooling copper pipe 4.

[0050] Reference Figure 4 Furthermore, in order to facilitate the fixing of the elastic locking part 10 with the locking connection part 11 at different positions or to adjust the pressure on the cooling copper pipe 4, the locking connection part 11 also includes a first connection part 111, a second connection part 112, a connecting spring 113 and a connecting adjustment block 114. The first connection part 111 is fixedly installed on the inner wall of the combined machine head 1, and the second connection part 112 passes through and slides to engage with the first connection part 111 on the side away from the inner wall of the combined machine head 1.

[0051] Continue to refer to Figure 4 A connecting spring 113 is connected at one end to the first connecting part 111 and at the other end to the second connecting part 112, so as to apply a spring force to the second connecting part 112 to move away from the first connecting part 111. A locking groove 12 is formed on the side of the second connecting part 112 away from the first connecting part 111. A connecting adjusting block 114 passes through the first connecting part 111 away from the locking fixing part 9 and slides to engage with the first connecting part 111. An adjusting screw 14 is rotatably mounted on the end of the connecting adjusting block 114 away from the locking fixing part 9. An L-shaped connecting fixing plate 15 is fixedly connected to the side of the first connecting part 111 away from the locking fixing part 9. The adjusting screw 14 passes through and is threaded to the connecting fixing plate 15, so that when the adjusting screw 14 is rotated, the connecting adjusting block 114 moves toward or away from the first connecting part 111.

[0052] Continue to refer to Figure 4 An adjusting slope 1141 is provided on the side of the connecting adjusting block 114 facing the first connecting part 111, and an adjusting hole 16 is provided on the side of the second connecting part 112 facing the connecting adjusting block 114. The adjusting slope 1141 abuts against the hole wall of the adjusting hole 16 near the combined machine head 1, so that when the connecting adjusting block 114 moves in the direction that drives the adjusting slope 1141 to move closer to or away from the second connecting part 112, the second connecting part 112 moves closer to or away from the inner wall of the combined machine head 1 due to the abutment between the hole wall of the adjusting hole 16 and the adjusting slope 1141 and under the action of the elastic force of the connecting spring 113, thereby facilitating the fine adjustment of the position of the second connecting part 112.

[0053] In addition, refer to Figure 3 and Figure 5 In this embodiment, the cooling connector 5 specifically includes a cooling fixing head 51 and a cooling fixing component 52. The cooling fixing head 51 is vertically fixedly installed on the combined machine head 1 and has a cooling through groove 17 that runs through it along its own axis. One end of the cooling copper pipe 4 is connected to the bottom of the cooling through groove 17. The cooling fixing component 52 is fixedly installed in the cooling through groove 17 and has multiple cooling through holes 18 that are evenly distributed circumferentially around its own axis and run vertically through it to ensure the unobstructed flow of the cooling through groove 17.

[0054] Reference Figure 5A connecting connector 19 is provided at one end of the hose near the cooling connector 5. The connecting connector 19 includes a connecting fixing head 191, a connecting fixing member 192, a connecting cooling spring 193, and a connecting stop member 194. The connecting fixing head 191 is fixedly installed at one end of the hose and has a cooling channel 20 that runs along its own axis and communicates with the hose. The hose communicates with the cooling channel 20. The connecting fixing member 192 is fixedly installed in the cooling channel 20 and has multiple cooling through holes 21 that are evenly distributed circumferentially around its own axis and vertically penetrate it to ensure the unobstructed flow of the cooling channel 20.

[0055] Continue to refer to Figure 5 The connecting cooling spring 193 is sleeved and installed on the connecting fastener 192 and applies a spring force to the connecting stop 194 in a direction away from the connecting fastener 192. The connecting stop 194 is sleeved and fixed with a connecting sealing ring 22. Under normal conditions, the connecting stop 194 is pressed against the groove wall of the second cooling channel 20 under the action of the spring force of the connecting cooling spring 193, so as to seal the end of the groove of the second cooling channel 20, making it difficult for the coolant in the hose to leak out during connection.

[0056] Continue to refer to Figure 5 The top of the cooling connector 5 has a connecting groove 23 that communicates with the cooling channel 17. The diameter of the connecting groove 23 is larger than the diameter of the cooling channel 17. One end of the connecting connector 19 is inserted into the connecting groove 23. When the connecting connector 19 is inserted into the connecting groove 23, the cooling fixing member 52 presses against the connecting stop member 194, thereby releasing the blocking of the opening of the cooling channel 20 by the connecting stop member 194, and realizing the communication between the cooling channel 17 and the cooling channel 20.

[0057] Continue to refer to Figure 5 To ensure the connection stability between the cooling connector 5 and the connecting connector 19, the cooling connector 5 is provided with a fixing component. Specifically, the fixing component includes a fixing spring 24, a fixing sleeve 25, and fixing balls 26. The outer circumferential surface of the cooling fixing head 51 has multiple fixing receiving grooves 27 that pass through its own axis and are used to accommodate the fixing balls 26. The outer circumferential surface of the connecting fixing head 191 has an annularly arranged ball retaining groove 28, which corresponds to each fixing receiving groove 27. The fixing sleeve 25 is fitted and slidably fitted onto the cooling fixing head 51. One end of the fixing spring 24 is connected to the cooling fixing head, and the other end is connected to the fixing sleeve 25 to apply a spring force to the fixing sleeve 25 in the direction of the fixing balls 26. A fixing retaining ring 29 is fixedly provided on the outer circumferential surface of the cooling fixing head 51 to limit the sliding position of the fixing sleeve 25.

[0058] The fixed sliding sleeve 25 has a fixed movable groove 30 at the end away from the cooling fixed head 51. When the fixed sliding sleeve 25 is pressed so that the fixed movable groove 30 corresponds with each fixed receiving groove 27, the fixed ball 26 can be partially located in the fixed movable groove 30. At this time, after the connecting connector 19 is inserted into the connecting groove 23, the ball retainer groove 28 corresponds with each fixed receiving groove 27. After the fixed sliding sleeve 25 is released, the fixed sliding sleeve 25 presses against each fixed ball 26 so that each fixed ball 26 is inserted into the ball retainer groove 28, thereby achieving a stable fixation between the cooling connector 5 and the connecting connector 19, which is convenient and quick.

[0059] The embodiments in this application are the same as those in Embodiment 1, and will not be repeated here.

[0060] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
