Description

Technical Field

[0001] The present invention relates to the technical field of engines, and in particular to a rotary engine and a use method thereof. Background Art

[0002] The internal space (or cycloidal chamber) of the housing of a rotary engine is always divided into three working chambers. During the movement of the rotor, the volumes of the three working chambers change continuously, and the four processes of intake, compression, combustion and exhaust are completed successively in the cycloidal cylinder. Each process is carried out at a different position in the cycloidal cylinder. The expansion pressure of the rotary engine acts on the side of the rotor, thereby pushing one of the three faces of the triangular rotor toward the center of the eccentric shaft. This movement is carried out under the action of two force components, one is the centripetal force pointing to the center of the output shaft, and the other is the tangential force that rotates the output shaft. The existing rotary engine has a simple structure, cannot provide a high compression ratio, has insufficient fuel mixing, and has low combustion efficiency, which results in increased fuel consumption and emission pollution. However, ordinary piston internal combustion engines have many transmission parts, too much power loss, and a complex structure, which is inconvenient to maintain and expensive. Summary of the invention

[0003] In order to solve the technical defects mentioned in the above background technology, an object of the present invention is to provide a rotary engine and a method for using the same.

[0004] In order to achieve the above object, the present invention adopts the following technical solution:

[0005] A rotary engine, comprising a front air compression device, a cylinder body, a transmission shaft and a rotor; the front air compression device comprises a turbine cylinder; a compression chamber is arranged inside the turbine cylinder, one end of the turbine cylinder is arranged with an air inlet for external air to enter the compression chamber, and the other end of the turbine cylinder is connected to one end of the cylinder body; a fuel nozzle for conveying fuel to the compression chamber is arranged on the circumferential side of the other end of the turbine cylinder; a mixed gas inlet connected to the inside of the cylinder body is arranged on the end face of the other end of the turbine cylinder; one end of the rotor passes through the cylinder body, and the first fan blade on the circumferential side of the rotor and the inner side wall of the cylinder body are divided into a plurality of cavities for mixed gas to do work; the transmission shaft passes through the front air compression device, the cylinder body and the rotor in sequence.

[0006] By adopting the above technical solution, the turbine cylinder in the front air compression device can compress the input air to provide high pressure, and the intake and compression are realized in the turbine cylinder, which simplifies the compression process and improves the transmission efficiency. The fuel sprayed at the fuel nozzle is mixed with the air to form a mixed gas. Under the action of high pressure, the mixed gas enters the cavity formed by the rotor and the cylinder body through the mixed gas inlet to perform work, so that the rotor drives the transmission shaft to rotate at a high speed, increases the pre-pressurization, and can achieve a high compression ratio. Therefore, it can work at the optimal compression ratio, thereby obtaining a high energy efficiency ratio. The transmission structure is simple, the compression process is simplified, the transmission efficiency is improved, the fuel burns fully, the cost is low, and the processing is simple.

[0007] Furthermore, the mixed gas inlet is configured as a funnel-shaped structure, and the end surface area of ​​the mixed gas inlet at one end of the compression chamber is larger than the end surface area of ​​the other end of the mixed gas inlet. While omitting the pressure guide plate, the mixed gas can be pressed into the corresponding cavity to form an intake and compression stroke, with high transmission efficiency and a high compression ratio.

[0008] Furthermore, the rotor is provided with three first blades at equal intervals along the central axis direction thereof. A cavity is enclosed between two adjacent first blades and the inner side wall of the cylinder body. The cavity includes a high-pressure chamber, an ignition chamber and an exhaust chamber which are arranged adjacent to each other in sequence. The other end of the mixture air inlet is connected to the high-pressure chamber. The rotary engine also includes an igniter, which is arranged in the ignition chamber. The cylinder body is provided with an exhaust port connected to the outside at the exhaust chamber. The ignition chamber provides ultra-high pressure, and the high-pressure exhaust gas is discharged to form a negative pressure, so that the rotor drives the transmission shaft to rotate unidirectionally at high speed and transmit power, and the transmission structure is simple and the cost is low.

[0009] Furthermore, the front air compression device also includes a pressure relief pipe, one end of which is connected to the compression chamber, and the other end of which is connected to the high-pressure chamber, so as to balance the pressure between the high-pressure chamber and the intake end of the mixed gas inlet port, thereby improving the intake efficiency.

[0010] Furthermore, a pressure reducing valve and a pressure sensor are provided at the other end of the pressure relief pipe. The pressure reducing valve is fixed on the cylinder body, and the pressure sensor is fixed on the other end of the pressure relief pipe, so as to improve the accuracy and efficiency of pressure regulation.

[0011] Furthermore, an oil film is provided between the peripheral side of the first blade and the inner wall of the cylinder body, so as to improve the sealing performance and lubricate the third blade and the inner wall of the cylinder body, thereby saving costs and extending the service life.

[0012] Further, the turbine cylinder includes a compression cylinder, a multi-leaf second blade, a multi-leaf third blade and a plurality of connecting bearings. The compression cylinder is provided with the compression chamber, and the inner side wall of the compression cylinder is provided with a multi-leaf second blade at intervals along the central axis direction thereof. The multi-leaf third blade is fixedly arranged at intervals along the length direction of the transmission shaft, and a group of the third blades is provided between two adjacent second blades. A connecting bearing is fixedly connected between two adjacent third blades. A compression channel connecting the air inlet and the mixed gas inlet is formed between the plurality of second blades and the plurality of third blades, and the air pressure at one end of the compression channel close to the air inlet is lower than the air pressure at one end of the compression channel located at the mixed gas inlet. Intake and compression are realized in the turbine cylinder, which simplifies the compression process and improves the transmission efficiency. Moreover, the high-pressure airflow under the high-speed rotation of the third blade can mix the fuel sprayed from the fuel nozzle at a high speed, and then press it into the cylinder through the mixed gas inlet, which can make the fuel burn more fully and improve the thermal efficiency.

[0013] Furthermore, the pre-air compression device also includes a plurality of elastic members and a locking block. One of the elastic members is provided on each of the connecting bearings. The locking block is fixedly mounted on the transmission shaft, and the locking block is fixedly connected to one of the third blades. When the air pressure at one end of the compression channel located at the mixed gas inlet is greater than a set pressure value, the plurality of elastic members are compressed, and the locking block is separated from the corresponding third blade. When the air pressure at the inlet end of the mixed gas inlet is too high, an axial force is generated to compress and move the third blade along one side of the air inlet, and the third blade is separated from the locking block, thereby reducing the air pressure at the inlet end of the mixed gas inlet and improving safety performance. When the pressure is insufficient, the third blade is locked into the locking block again under the action of the elastic member, and pressure is supplied to the compression channel again.

[0014] Furthermore, a plurality of groups of the rotary engines are arranged in parallel or in series.

[0015] A method for using a rotary engine, comprising any of the rotary engines described above, further comprising:

[0016] Step S1, the third blade of the turbine cylinder rotates to drive air to be transported to the area corresponding to the fuel nozzle through the air intake port and the compression channel, and the air is compressed under the action of the multi-blade third blade; synchronously, the fuel pump injects fuel from the fuel nozzle into one end of the compression channel close to the mixed gas intake port for mixing;

[0017] Step S2, the gas mixed by the third fan blade is transported from the mixed gas inlet to the high-pressure chamber, and the pressure relief pipe and the pressure sensor cooperate to control the pressure in the high-pressure chamber to be stable at a set value;

[0018] Step S3: The rotation of the first two blades corresponding to the high-pressure chamber drives the mixed gas in the high-pressure chamber to move to the ignition chamber; synchronously, the exhaust gas burned in the ignition chamber is transferred to the exhaust chamber, and the enclosed area in the exhaust chamber that has previously exhausted the exhaust gas rotates to the position of the high-pressure chamber, and the mixed gas is continuously transported from the compression chamber to the high-pressure chamber through the mixed gas inlet;

[0019] Step S4: At this point, the three-stroke single operation is completed; repeat the three-stroke operation to continuously drive the transmission shaft to rotate.

[0020] In summary, the beneficial effects of the present invention are:

[0021] The present invention can compress the input air to provide high pressure through the turbine cylinder in the front air compression device, and realize air intake and compression in the turbine cylinder, which simplifies the compression process and improves the transmission efficiency. The fuel sprayed at the fuel nozzle is mixed with air to form a mixed gas. Under the action of high pressure, the mixed gas enters the cavity formed by the rotor and the cylinder body through the mixed gas inlet to do work, so that the rotor drives the transmission shaft to rotate at a high speed, increases the front pressure, and can achieve a high compression ratio. Therefore, it can work under the optimal compression ratio, thereby obtaining a high energy efficiency ratio. The transmission structure is simple, the compression process is simplified, the transmission efficiency is improved, the fuel burns fully, the cost is low, and the processing is simple.

[0030] The following is combined with Figure 1-3 , the embodiments of the present invention are described in further detail.

[0031] A rotary engine 1, such as Figure 1 , Figure 2As shown, it includes a pre-air compression device, a cylinder body 3, a transmission shaft 4 and a rotor 5. The pre-air compression device includes a turbine cylinder 21. A compression chamber is arranged inside the turbine cylinder 21, and an air inlet 22 for external air to enter the compression chamber is arranged at one end of the turbine cylinder 21, and the other end of the turbine cylinder 21 is connected to one end of the cylinder body 3. A fuel nozzle 23 for delivering fuel to the compression chamber is arranged on the circumference of the other end of the turbine cylinder 21. The end face of the other end of the turbine cylinder 21 is provided with a mixed gas inlet 6 connected to the inside of the cylinder body 3. One end of the rotor 5 penetrates the cylinder body 3, and the first fan blade 51 on the circumference of the rotor 5 and the inner side wall of the cylinder body 3 are divided into a plurality of cavities for mixed gas to do work. The transmission shaft 4 sequentially penetrates the pre-air compression device, the cylinder body 3, and the rotor 5.

[0032] Among them, the turbine cylinder 21 in the front air compression device can compress the input air to provide high pressure, and the intake and compression are realized in the turbine cylinder 21, which simplifies the compression process and improves the transmission efficiency. The fuel sprayed at the fuel nozzle 23 is mixed with the air to form a mixed gas. Under the action of high pressure, the mixed gas enters the cavity formed by the rotor 5 and the cylinder body 3 through the mixed gas inlet 6 to perform work, so that the rotor 5 drives the transmission shaft 4 to rotate at a high speed, increases the pre-pressurization, and can achieve a high compression ratio. Therefore, it can work at the best compression ratio, thereby obtaining a high energy efficiency ratio. The transmission structure is simple, the compression process is simplified, the transmission efficiency is improved, the fuel burns fully, the cost is low, and the processing is simple.

[0033] In some embodiments, please refer to Figure 1 The mixed gas inlet 6 is configured as a funnel-shaped structure, and the end surface area of ​​the mixed gas inlet 6 at one end of the compression chamber is larger than the end surface area of ​​the other end of the mixed gas inlet 6. While eliminating the pressure guide plate, the mixed gas can be pressed into the corresponding cavity to form an intake and compression stroke, with high transmission efficiency and a high compression ratio.

[0034] The air inlet end of the mixed gas inlet port 6 is arranged on the sealing end surface of the other end of the turbine cylinder 21 , and the air outlet end of the mixed gas inlet port 6 is arranged on the sealing end surface of one end of the cylinder body 3 close to the turbine cylinder 21 .

[0035] In some embodiments please refer to Figure 1 , Figure 2 , Figure 3, the rotor 5 is provided with three-leaf first blades 51 at equal intervals along the direction of its central axis. A cavity is enclosed between two adjacent first blades 51 and the inner side wall of the cylinder body 3. The cavity includes a high-pressure chamber 31, an ignition chamber 32 and an exhaust chamber 33 which are arranged adjacent to each other in sequence. The other end of the mixture air inlet 6 is connected to the high-pressure chamber 31. The rotary engine 1 also includes an igniter 7, which is arranged in the ignition chamber 32. Specifically, the igniter 7 is arranged in the inner side wall of the corresponding cylinder body 3. The cylinder body 3 is provided with an exhaust port 34 connected to the outside at the exhaust chamber 33. The ignition chamber 32 provides ultra-high pressure, and the high-pressure exhaust gas is discharged to form a negative pressure, so that the rotor 5 drives the transmission shaft 4 to rotate unidirectionally at high speed and transmit power, and the transmission structure is simple and the cost is low.

[0036] The length direction of the first blade 51 is arranged along the central axis, and the side end surface of the first blade 51 is arranged corresponding to the inner wall of the cylinder 3 to maintain a set spacing. Two adjacent first blades 51, the inner wall of the cylinder 3, one end of the cylinder 3 provided with the mixed gas inlet 6, and the end of the rotor 5 away from the first blade 51 form a cavity. The other end of the cylinder 3 is provided with a cylinder head 8, which can seal the rotor 5 in the cylinder 3 to improve the sealing performance to ensure high-pressure operation.

[0037] The high-temperature and high-pressure mixed gas enters the high-pressure chamber 31 formed by the cylinder 3 and the rotor 5. At the same time, the igniter 7 is also exposed in the ignition chamber 32 and receives the ignition signal to ignite and do work. Since the exhaust chamber 33 is provided with an exhaust port 34, the high-pressure exhaust gas is discharged through the exhaust port 34 to form a negative pressure. Therefore, the rotor 5 will drive the transmission shaft 4 to rotate unidirectionally at high speed and transmit power.

[0038] In some embodiments, please refer to Figure 1 , Figure 3 The front air compression device also includes a pressure relief pipe 24, one end of which is connected to the compression chamber, and the other end of the pressure relief pipe 24 is connected to the high-pressure chamber 31, balancing the pressure of the high-pressure chamber 31 and the intake end of the mixed gas intake port 6, thereby improving the intake efficiency.

[0039] The other end of the pressure relief pipe 24 is also provided with a pressure reducing valve 25 and a pressure sensor 26. The pressure reducing valve 25 is fixed on the cylinder body 3, and the pressure sensor 26 is fixed on the other end of the pressure relief pipe 24 to improve the accuracy and efficiency of pressure regulation. The pressure sensor 26 arranged in the cylinder body 3 senses the pressure and uses the pressure reducing valve 25 to control the pressure relief pipe 24 to adjust the pressure in the cylinder body 3. Among them, one end of the pressure reducing valve 25 is connected to the pressure sensor 26, and the other end of the pressure reducing valve 25 is connected to the other end of the pressure relief pipe 24.

[0040] Among them, the other end of the pressure relief pipe 24 , the pressure reducing valve 25 and the pressure sensor 26 are all installed at the pressure relief port 35 set in the high-pressure chamber 31 of the cylinder body 3 , and the pressure reducing valve 25 and the pressure sensor 26 are all set in the pressure relief port 35 .

[0041] An oil film is provided between the peripheral side of the first blade 51 and the inner wall of the cylinder body 3, which improves the sealing performance and can also lubricate the third blade 213 and the inner wall of the cylinder body 3, saving costs and extending the service life.

[0042] In some cases, please refer to Figure 1 , the turbine cylinder 21 includes a compression cylinder 211, a multi-leaf second blade 212, a multi-leaf third blade 213 and a plurality of connecting bearings. A compression chamber is arranged inside the compression cylinder 211, and a multi-leaf second blade 212 is arranged at intervals on the inner side wall of the compression cylinder 211 along the direction of its central axis. The multi-leaf third blade 213 is fixedly arranged at intervals along the length direction of the transmission shaft 4. Specifically, the spacing between two adjacent second blades 212 is fixedly arranged. A group of third blades 213 is arranged between two adjacent second blades 212. A connecting bearing is fixedly connected between two adjacent third blades 213. A compression channel 216 connecting the air inlet 22 and the mixed gas inlet 6 is formed between the plurality of second blades 212 and the plurality of third blades 213, and the air pressure at one end of the compression channel 216 close to the air inlet 22 is lower than the air pressure at one end of the compression channel 216 located at the mixed gas inlet 6. The intake and compression are realized in the turbine cylinder 21, which simplifies the compression process and improves the transmission efficiency. Moreover, the high-pressure airflow under the high-speed rotation of the third blade 213 can rotate and mix the fuel sprayed from the fuel nozzle 23 at high speed, and then press it into the cylinder body 3 through the mixed gas intake port 6, which can make the fuel burn more fully and improve the thermal efficiency.

[0043] In order to solve the problem of poor oil-gas mixing in the rotary engine 1, there should be a high-pressure area and a low-pressure area in the compression chamber of the front air compression device. The compression chamber is located at one end of the air inlet 22 and is set as a low-pressure area. The incoming air is compressed and transported to the other end of the compression chamber through the high-speed rotation of the third blade 213 and the cooperation of the second blade 212, thereby forming a high-pressure area at the other end of the compression chamber. Among them, the second blade 212 is a stationary blade, and the third blade 213 is a moving blade. The fuel nozzle 23 is arranged on the side of the mixed gas inlet 6, and is fully stirred and mixed with the air under the high-speed rotation force of the third blade 213, so that high-speed rotation pressurization and fuel mixing can be achieved. Among them, the fuel sprayed at the fuel nozzle 23 can be changed to natural gas or hydrogen, etc.

[0044] In some embodiments, please refer to Figure 1, the front air compression device also includes a plurality of elastic members 214 and a locking block 215. An elastic member 214 is provided on each connecting bearing. The locking block 215 is fixedly mounted on the transmission shaft 4, and the locking block 215 is fixedly connected to one of the third blades 213. When the air pressure at one end of the compression channel 216 located at the mixed gas inlet 6 is greater than the set pressure value, the plurality of elastic members 214 are compressed, and the locking block 215 is separated from the corresponding third blade 213. When the air pressure at the inlet end of the mixed gas inlet 6 is too high, an axial force is generated to compress and move the third blade 213 along one side of the air inlet 22, and the third blade 213 is separated from the locking block 215, thereby reducing the air pressure at the inlet end of the mixed gas inlet 6 and improving safety performance. When the pressure is insufficient, the third blade 213 is locked into the locking block 215 again under the action of the elastic member 214, and pressure is supplied to the compression channel 216 again.

[0045] The locking block 215 is provided with a rack on its circumferential side, the length direction of the rack is consistent with the direction of the transmission shaft 4, and the third blade 213 is meshedly connected with the locking block 215. The elastic member 214 can be provided as a spring or a compression spring fork, and a spring is preferred in this embodiment. If the elastic member 214 is provided as a compression spring fork, the locking block 215 can be actively opened and closed by the provided hydraulic pump to regulate the pressure in the compression chamber.

[0046] In some embodiments, multiple groups of rotary engines 1 are arranged in parallel or in series to increase the power of the engine. The rotary engine 1 is a three-stroke engine. Among them, the intake and compression in the turbine cylinder 21 are regarded as the first stroke, the ignition work in the ignition chamber 32 is the second stroke, and the pressure relief in the exhaust chamber 33 is the third stroke. Therefore, the rotary engine 1 can be arranged in multiple groups with three strokes as a group, and assembled in series or in parallel. The rotary engine 1 can be used in the fields of automobiles, small and medium-sized ships, small aircraft, helicopters, drones, etc.

[0047] In some embodiments, the front air compression device can also be configured as a centrifugal compression assembly or a volumetric compression assembly, and the centrifugal compression assembly or the volumetric compression assembly is connected to the cylinder body 3. The rest of the structure can refer to the above content.

[0048] Initially, a certain rotational driving force is given to the transmission shaft 4 by external force, so that the igniter 7 in the rotor 5 is electronically ignited, and the starter drives the front air compression device to rotate at a high speed, thereby driving the filtered air to enter the compression chamber from the air inlet 22, and start to generate high pressure. At the same time, the ECU sends a signal, and the fuel pump injects fuel from the fuel nozzle 23, which is fully mixed with the air in the high-pressure and high-rotation environment created by the front air compression device to form a mixed gas, and the mixed gas is injected into the high-pressure chamber 31 formed by the cylinder 3 and the rotor 5 through the mixed gas inlet 6. Because the exhaust chamber 33 at the exhaust port 34 is at normal pressure, a pressure difference is formed with the high-pressure chamber 31 where the fuel is injected, and driven by the starter, the rotor 5 will rotate unidirectionally in the cylinder 3. After the fuel high pressure enters the high-pressure chamber 31, data is transmitted through the pressure sensor 26, and the ECU will issue a command to open and close the pressure reducing valve 25 to control the pressure in the cylinder 3 through the pressure relief pipe 24. The rotation of the first blade 51 can carry the mixed gas mist in the high-pressure chamber 31 to the ignition chamber 32, and the electronic igniter 7 receives the instruction to ignite. Therefore, after the engine is started, there will be at least one high-pressure chamber and one ignition chamber 32 for ultra-high-pressure explosion and a normal-pressure exhaust chamber 33 for exhaust. In the opening and closing of the pressure reducing valve 25 under the control of the ECU, it becomes a rotor 5-type engine with a variable compression ratio.

[0049] A method for using a rotary engine 1, comprising any of the rotary engines 1 described above, further comprising:

[0050] Step S1, the third blade 213 of the turbine cylinder 21 rotates to drive the air to be transported to the area corresponding to the fuel nozzle 23 through the air intake port 22 and the compression channel 216, and the air is compressed under the action of the multi-leaf third blade 213; synchronously, the fuel pump injects the fuel from the fuel nozzle 23 into one end of the compression channel 216 close to the mixed gas intake port for mixing;

[0051] Step S2, the gas mixed by the third fan blade 213 is transported from the mixed gas inlet 6 to the high-pressure chamber 31, and the pressure relief pipe 24 and the pressure sensor 26 cooperate to control the pressure in the high-pressure chamber 31 to be stable at a set value;

[0052] Step S3: The two first blades 51 corresponding to the high-pressure chamber 31 rotate to drive the mixed gas in the high-pressure chamber 31 to move to the ignition chamber 32; synchronously, the exhaust gas burned in the ignition chamber 32 is transferred to the exhaust chamber 33, and the enclosed area in the exhaust chamber 33 that has previously exhausted the exhaust gas rotates to the position of the high-pressure chamber 31, and the mixed gas is continuously transported from the compression chamber to the high-pressure chamber 31 through the mixed gas inlet 6;

[0053] Step S4: At this point, the three-stroke single operation is completed; repeat the three-stroke operation to continuously drive the transmission shaft 4 to rotate.

[0054] Specifically, in step S1, the compression channel 216 formed by the third fan blade 213 and the second fan blade 212 can compress the incoming air to form a high-pressure state. In the high-pressure area, the fuel pump injects fuel from the fuel nozzle 23 to the end of the compression channel 216 close to the mixture inlet 6, and the fuel is fully stirred and mixed with the air under the high-speed rotation force of the third fan blade 213, thereby achieving high-speed rotation pressurization and full mixing of the fuel.

[0055] In step S2, the pressure sensor 26 cooperates with the pressure relief pipe 24 to balance the air pressure in the high pressure area of ​​the compression chamber and the air pressure in the high pressure chamber 31, so that the mixed gas in the high pressure area is pressed into the high pressure chamber 31 through the mixed gas inlet 6. When the pressure sensor 26 detects that the pressure value in the high pressure chamber 31 is greater than the set value, the pressure reducing valve 25 opens the pressure relief pipe 24 to release the pressure, so that the pressure in the high pressure chamber 31 is maintained at the set value to ensure the stability of the transmission.

[0056] In step S3, the rotation of the two first blades 51 corresponding to the high-pressure chamber 31 drives the mixed gas in the high-pressure chamber 31 to move to the ignition chamber 32. Synchronously, the exhaust gas burned in the ignition chamber 32 is transferred to the exhaust chamber 33. The enclosed area in the exhaust chamber 33 that has previously exhausted the exhaust gas rotates to the position of the high-pressure chamber 31, and the mixed gas continues to be transported from the compression chamber to the high-pressure chamber 31 through the mixed gas inlet 6. The igniter 7 obtains the ignition instruction and ignites to explode the mixed gas. The high-pressure chamber 31, the ignition chamber 32, and the exhaust chamber 33 are arranged in a ring shape. The mixed gas enters the high-pressure chamber 31, the fuel in the ignition chamber 32 is ignited and exploded, and the exhaust gas after the explosion is discharged from the exhaust chamber 33. The three are carried out simultaneously.

[0057] In step S4 , the three-stroke cycle continues to operate, continuously providing driving force to the transmission shaft 4 to rotate the transmission shaft 4 .

[0058] The front air compression device can realize intake and compression, simplify the compression process, and improve the transmission efficiency. The fuel injected at the fuel nozzle 23 is mixed with air to form a mixed gas. The mixed gas enters the cavity formed by the rotor 5 and the cylinder 3 through the mixed gas inlet 6 under the action of high pressure to perform work, so that the rotor 5 drives the transmission shaft 4 to rotate at a high speed, thereby realizing a variable compression ratio, so that it can work at an optimal compression ratio and obtain a high energy efficiency ratio.

[0059] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
