[0024] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0025] In the description of the present application, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0026] Reference Figures 1 to 5 According to the first aspect of the present application, an electronic cigarette includes: a host 100 and a first suction structure.

[0027] The host 100 is provided with two installation slots 110 ; specifically, the installation slots 110 are provided at the upper end of the host 100 , and the installation slots 110 are arranged adjacent to each other.

[0028] The first suction structure includes two first cigarette cartridges 200, the first cigarette cartridges 200 correspond to the mounting slots 110 one by one, and the first cigarette cartridges 200 are plugged and matched with the mounting slots 110;

[0029] It should be noted that the host 100 is used to supply power to the first cigarette cartridge 200 so that the first cigarette cartridge 200 atomizes the cigarette oil to generate smoke.

[0030] Specifically, the two first cigarette cartridges 200 store different flavors of e-liquid. Since the first cigarette cartridge 200 is pluggable and arranged in the mounting slot 110, after the e-liquid in the cigarette cartridge is used up, the cigarette cartridge can be pulled out from the mounting slot 110 and replaced with a new one, so that the host 100 can be reused, reducing resource waste. In addition, the first cigarette cartridges 200 of different flavors can be replaced at any time.

[0031] Since an electronic cigarette of the present application has two first cartridges 200, the user can inhale two first cartridges 200 of different flavors through the two first cartridges 200 at the same time, and can experience a third flavor due to the mixture of the two flavors. In addition, the user can also inhale one of the first cartridges 200 alone. It should also be understood that since the first cartridge 200 is detachably connected to the host 100, the user can conveniently replace one or both cartridges to change the mixed flavor.

[0032] The first cigarette cartridge 200 includes a shell 210, a first fixing portion 220, a heating component and a heat insulation structure 270. The heating component is arranged in the shell 210, and a first oil storage chamber 211 is formed between the heating component and the shell 210; an atomization chamber 221 is formed inside the heating component, and a suction nozzle 212 is formed in the shell 210. The atomization chamber 221 is connected to the first oil storage chamber 211, and the atomization chamber 221 is connected to the suction nozzle 212; the heat insulation structure 270 is arranged between the shell 210 and the heating component; the host 100 and the heating component are electrically connected.

[0033] It is understandable that the tobacco oil in the first oil storage chamber 211 can enter the heating component, and the heating component heats up to atomize the tobacco oil in the first oil storage chamber 211 to form smoke in the atomizing chamber 221, and the smoke can pass through the suction nozzle 212 for inhalation. It should be understood that the heating component generates a certain amount of heat, and the heat insulation structure 270 can block the heating component and the housing 210 to reduce the heat transferred from the heating component to the housing 210, so as to avoid overheating of the housing 210 and affect the user's experience.

[0034] Specifically, the heating component includes a first fixed part 220, a first oil guide structure 230, a first heating structure 240 and a bracket structure 280. The first fixed part 220 is arranged in the housing 210, and a first oil storage chamber 211 is formed between the first fixed part 220 and the housing 210; an atomizing chamber 221 is formed inside the first fixed part 220, and a plurality of oil outlets 222 are formed around the first fixed part 220. The atomizing chamber 221 is connected to the first oil storage chamber 211 through the oil outlets 222, and the atomizing chamber 221 is connected to the suction nozzle 212; the first oil guide structure 230 is arranged in the atomizing chamber 221, and can shield the oil outlets 222, and the first heating structure 240 is arranged in the first oil guide structure 230; the host 100 is electrically connected to the first heating structure 240. The heat insulation structure 270 is arranged between the first fixed part 220 and the housing 210.

[0035] It can be understood that the first oil storage chamber 211 stores smoke oil. Since the first oil storage chamber 211 is connected to the atomizing chamber 221 through the oil outlet 222, the smoke oil can enter the atomizing chamber 221 through the oil outlet 222. Since the first oil guide structure 230 disposed in the atomizing chamber 221 can shield the oil outlet 222, the smoke oil flows to the first oil guide structure 230 through the oil outlet 222. The first oil guide structure 230 absorbs the smoke oil and guides the smoke oil to the first heating structure 240. Specifically, with respect to the specific structure of the first oil guide structure 230, in this embodiment, the first oil guide structure 230 is oil guide cotton. In other embodiments, it can also be chemical fiber cotton, absorbent cotton, etc. The first heating structure 240 disposed in the first oil guide structure 230 generates heat after being energized, so that the oil is heated and atomized, thereby generating smoke. Specifically, the first heating structure 240 can absorb the oil to directly atomize the absorbed oil. For example, the first heating structure 240 includes a ceramic block and a heating wire, the heating wire is embedded in the ceramic block, the ceramic block can absorb the oil, and the heating wire can generate heat after being energized to atomize the oil on the ceramic block. Then, the smoke in the atomization chamber 221 will be ejected from the suction nozzle 212 for inhalation.

[0036] It should be understood that the first oil guide structure 230 is disposed in the first fixing portion 220, and the first heating structure 240 is disposed in the first oil guide structure 230, and the occupied space is reduced by the layered surrounding structure. It should also be understood that the first heating structure 240 is disposed in the first oil guide structure 230 so that the first oil guide structure 230 surrounds the first oil guide structure 230, increasing the heating range of the first oil guide structure 230 to improve the atomization effect.

[0037] The heat-insulating structure 270 is disposed between the first fixing part 220 and the shell 210. It should be understood that a first heating structure 240 is disposed inside the first fixing part 220 to atomize the e-liquid, and thus, the first fixing part 220 is configured to be made of a high-temperature resistant material, such as metal. A suction nozzle 212 for suction is provided on the shell 210, and thus, the mouth of the smoker will touch the shell 210. In order to prevent the heat of the first fixing part 220 from being transferred to the shell 210, a heat-insulating structure is disposed between the first fixing part 220 and the shell 210, and the heat-insulating structure 270 is made of, for example, silicone. Specifically, one end of the heat-insulating structure 270 is sleeved on the outside of the first fixing part 220, and the other end is inserted into the airway 216, so as to achieve the fixation of the heat-insulating structure 270.

[0038] Among them, refer to Figure 4 , Figure 5 and Fig.10The support structure 280 is arranged in the first fixed part 220, and a plurality of through holes 281 and a through groove 282 are provided on the support structure 280, and the oil outlet 222 corresponds to the through hole 281 or the through groove 282; the first heating structure 240 is arranged in the support structure 280, and the first oil guide structure is partially covered on the outside of the support structure 280, and partially passes through the through groove 282 to cover the outside of the first heating structure 240.

[0039] It can be understood that, in this embodiment, referring to Fig.10 , there are four oil outlets 222 and three through holes 281, each through hole 281 corresponds to an oil outlet 222, and one through slot 282 corresponds to an oil outlet, so that after the smoke oil comes out of the oil outlet 222, it can easily enter the support structure 280 through the through hole 281, so that the first heating structure 240 can atomize the smoke oil. It should be understood that in this embodiment, the first oil guide structure 230 is a circle of oil guide cotton, and the first oil guide structure 230 is partially wound around the outside of the support structure 280, and partially passes through the through slot 282 to be wound around the outside of the first heating structure 240, and the through slot 282 can be used to pass through the first oil guide structure 230. It should be noted that the through slot 282 is relatively large in the height direction, which is larger than the size of the through hole 281. Only one through slot 282 can ensure the normal installation of the first oil guide structure 230 while reducing the risk of smoke oil leaking from the through slot 282.

[0040] In order to prevent the e-liquid in the first oil storage chamber 211 from being exhausted, refer to Figure 4 and Figure 5 The oil outlet 222 is arranged corresponding to the bottom of the first oil storage chamber 211 to ensure that the tobacco oil in the first oil storage chamber 211 can be used up.

[0041] In order to enable the first cigarette cartridge 200 to be reused, refer to Figure 4 The outer wall of the shell 210 is provided with a first oil filling port 214 connected to the first oil storage chamber 211, and a first cover plate 215 detachable from the shell 210 is provided corresponding to the first oil filling port 214, and the first cover plate 215 can close or open the first oil filling port, and the movable end of the first cover plate 215 forms an air guide groove 2151 toward one side of the first oil storage chamber, and the groove wall of the air guide groove 2151 is formed with an inclined surface inclined toward the first oil filling port.

[0042] It is understandable that when the e-liquid in the first oil storage chamber 211 is used up, the first cover plate 215 can be opened, and the first oil storage chamber 211 can be filled with e-liquid through the first oil filling port 214, so that the first e-liquid cartridge 200 can be reused. In addition, it is also known that different flavors of e-liquid can be filled into the first oil storage chamber 211 through the first oil filling port 214, so as to replace the e-liquid or mix the e-liquid. Specifically, the fixed end of the first cover plate 215 is fixedly connected to the shell body 210, and the movable end of the first cover plate 215 is detachably connected to the shell body 210. The movable end of the first cover plate 215 can be rotated relative to the fixed end of the first cover plate 215. Therefore, after the first oil storage chamber 211 is filled with oil, when the first cover plate 215 needs to be covered, the movable end of the first cover plate 215 is rotated in a direction close to the first oil storage chamber 211. Since the movable end of the first cover plate 215 is provided with an air guide groove 2151, the volume of the first cover plate 215 is reduced, so that when the first cover plate 215 is covered, too much air will not be squeezed into the first oil storage chamber 211, causing the smoke oil in the first oil storage chamber 211 to be squeezed into the atomization chamber 221, resulting in oil leakage. Furthermore, since a slope is formed on the groove wall of the air guide groove 2151, when the movable end of the first cover plate 215 gradually enters the first oil storage cavity 211, the gas in the first oil storage cavity 211 flows out to the outside along the slope, and the slope guides the airflow.

[0043] For the specific configuration of the first oil guide structure 230, refer to Figure 4 and Figure 5 The interior of the first oil guiding structure 230 is hollow to form a accommodating chamber 231, and the two ends of the first oil guiding structure 230 are respectively formed with a smoke outlet 232 and an air inlet 233 connected to the accommodating chamber 231. The first heating structure 240 is placed in the accommodating chamber 231, and the outer peripheral side of the first oil guiding structure 230 shields the oil outlet 222; the shell 210 is formed with an air inlet hole 213 connected to the outside, and the air inlet 233 is connected to the air inlet hole 213.

[0044] It is understandable that the external airflow can enter the housing 210 through the air inlet 213, and the airflow sequentially passes through the air inlet 233, the accommodating chamber 231, the smoke outlet 232 and the suction nozzle 212. Since the airflow enters the accommodating chamber 231, the effect of atomizing the smoke oil by the first heating structure 240 is ensured, and the atomized smoke diffuses in the accommodating chamber 231. Then, when the user draws on the suction nozzle 212, the smoke can be inhaled.

[0045] Specifically, the first oil guiding structure 230 is cylindrical, and the interior of the first oil guiding structure 230 is hollow, so that its cross section is annular.

[0046] For the specific configuration of the first heating structure 240, refer to Figure 5The interior of the first heating structure 240 is hollow to form a circulation channel 241 , and the circulation channel 241 is connected to the smoke outlet 232 and the air inlet 233 .

[0047] It can be understood that by making the interior of the first heating structure 240 hollow to form a circulation channel 241, the airflow can pass through the circulation channel 241, increasing the flow cross-section of the airflow when flowing through the atomization chamber 221, making the airflow flow smoother, increasing the flow rate of smoke outflow, and ensuring the smoking taste.

[0048] Specifically, the first heating structure 240 is cylindrical, and the interior of the first heating structure 240 is hollow, so that its cross section is annular. More specifically, the ceramic block is cylindrical.

[0049] Regarding the connection relationship between the first heating structure 240 and the first oil guide structure 230, in this embodiment, refer to Figure 5 The outer peripheral side of the first heating structure 240 is spaced apart from the inner side of the accommodating cavity 231 .

[0050] It can be understood that, since the outer peripheral side of the first heating structure 240 and the inner side of the accommodating cavity 231 are spaced apart, an annular flow channel 234 is formed between the first heating structure 240 and the first oil guiding structure 230, the smoke oil can flow into the annular flow channel 234, and the first heating structure 240 can heat up and atomize the smoke oil in the annular flow channel 234.

[0051] It should be understood that the first heating structure 240 can absorb smoke oil, and smoke can be generated and flowed out not only from between the annular flow channels 234, but also from the circulation channel 241, so as to increase the concentration of smoke and the flow rate of smoke.

[0052] In other embodiments, the first heating structure 240 may also be closely attached to the first oil guiding structure 230 to enhance the oil guiding effect of the first oil guiding structure 230 .

[0053] For the arrangement of the suction nozzle 212, refer to Figure 1 and Figure 4 The suction nozzle 212 is disposed at a corner end of the housing 210 .

[0054] It is understandable that the suction nozzle 212 is arranged at the corner end of the first cigarette cartridge 200 to facilitate the user to inhale. It should also be understood that an airway 216 is formed between the suction nozzle 212 and the atomizing chamber 221, and the suction nozzle 212 is arranged at an angle, resulting in a longer airway 216, and the first oil guide structure 230 is arranged in the first fixed part 220, and the first heating structure 240 is arranged in the first oil guide structure 230, that is, the first fixed part 220, the first oil guide structure 230, and the first heating structure 240 are stacked and coated in the horizontal direction to utilize the horizontal space, reduce the use of the height space, and enable the atomizing chamber 221 to be close to the suction nozzle 212, so as to offset the effect of the suction nozzle 212 being arranged at an angle to the longer airway 216, and enable the smoke to be ejected from the suction nozzle 212 without too much obstruction.

[0055] In order to facilitate the insertion of the first cigarette cartridge 200 relative to the mounting groove 110, in this embodiment, refer to Figure 1 and Figure 2 The two first cigarette cartridges 200 have the same shape, and the two mounting grooves 110 have the same shape, and the first cigarette cartridge 200 can be inserted into any mounting groove 110 .

[0056] It is understandable that the two first cigarette cartridges 200 have the same shape, so that the first cigarette cartridge 200 can be inserted into any installation slot 110, so as to facilitate the insertion of the first cigarette cartridge 200. It should also be understood that the first cigarette cartridge 200 has the same shape, and the first cigarette cartridges 200 of all flavors use the same first cigarette cartridge 200 shape, which can facilitate the production of the first cigarette cartridge 200 without the need for additional molds, and after the e-liquid in one of the first cigarette cartridges 200 is used up, the first cigarette cartridge 200 of any flavor can be replaced at will, without considering the problem that the first cigarette cartridge 200 is not compatible with the installation slot 110.

[0057] In other embodiments, the first cigarette cartridge 200 may also adopt different shapes.

[0058] In order to facilitate the first cigarette cartridge 200 to be smoked alone or two first cigarette cartridges 200 to be smoked together, refer to Figure 1 and Figure 6 , the first cigarette cartridge 200 placed in the mounting groove 110 has a forward state and a reverse state; wherein, referring to Figure 1 When the two first cigarette cartridges 200 are both in the forward state, the nozzles 212 of the two first cigarette cartridges 200 are arranged opposite to each other; Figure 6 When the two first cigarette cartridges 200 are in the reverse state, the nozzles 212 of the two first cigarette cartridges 200 are arranged opposite to each other.

[0059] Specifically, the first cigarette cartridge 200 in the forward state is converted into the reverse state after being rotated. It can be understood that the mounting groove 110 can adapt to the first cigarette cartridge 200 in the forward state, and can also adapt to the first cigarette cartridge 200 in the reverse state.

[0060] It can be understood that when both first cigarette cartridges 200 are in the forward state, the mouthpieces 212 of the two first cigarette cartridges 200 are arranged opposite to each other, so that the mouthpieces of the two first cigarette cartridges 200 are respectively located at two corners of an electronic cigarette of the present application. In this state, the user can conveniently consume one of the first cigarette cartridges 200 separately. When both first cigarette cartridges 200 are in the reverse state, the mouthpieces 212 of the two first cigarette cartridges 200 are arranged opposite to each other, so that the mouthpieces of the two first cigarette cartridges 200 are centered in the middle of an electronic cigarette of the present application. In this state, the user can conveniently consume two first cigarette cartridges 200 at the same time.

[0061] In order to realize the above-mentioned application scenarios of single smoking or mixed smoking, the electronic cigarette of the present application also includes a control module, which is arranged in the host 100, and the control module can control the conduction or disconnection of the electrical connection between the power supply 130 and the two first cigarette cartridges 200. For example, the control module controls the power supply 130 to be electrically connected to the two first cigarette cartridges 200 at the same time, and at the same time, the two first cigarette cartridges 200 are both in a reverse state, and the suction nozzles 212 of the two first cigarette cartridges 200 are close to each other and located in the middle of the electronic cigarette, and can both produce smoke to achieve mixed smoking. For another example, the control module controls the power supply 130 to be electrically connected to one of the first cigarette cartridges 200, cuts off the power supply to the other first cigarette cartridge 200, and makes the energized first cigarette cartridge 200 in a forward state, so that the suction nozzle 212 of the first cigarette cartridge 200 is located at the corner end, so that the user can smoke alone.

[0062] Specifically, the control module can control the power supply state of the power supply 130 to make the heating state of the first heating structure 240 in the two first cigarette cartridges 200 different, so that the concentration of the atomized smoke is inconsistent. Therefore, in the case of mixed smoking, more smoke with different tastes can be mixed by controlling the smoke concentration in the two first cigarette cartridges 200.

[0063] Specifically, refer to Figure 1 The electronic cigarette of the present application is square, and is a flat square, so as to reduce the volume of the electronic cigarette and facilitate carrying and grasping. It can be understood that the electronic cigarette of the present application is set in a square shape, so that its upper end has two corners for the placement of the nozzles 212 of the two first cigarette cartridges 200, so that the nozzles 212 of the two first cigarette cartridges 200 can be located at the two corners of the electronic cigarette of the present application.

[0064] Reference Figure 7 and Figure 8The electronic cigarette of the present application further includes a second suction structure, which includes a second smoke cartridge 300 and an oil storage tank 400 connected to each other, the oil storage tank 400 having a storage cavity 401 for storing smoke oil, the storage cavity 401 being connected to the second oil storage cavity 301 of the second smoke cartridge 300, and the second smoke cartridge 300 and the oil storage tank 400 are respectively plugged and matched with one mounting groove 110;

[0065] The host 100 can be selectively docked with one of the first suction structure and the second suction structure.

[0066] It is understandable that the use scenario of the electronic cigarette of the present application is increased by adding the second suction structure. For example, the user does not need to inhale smoke of two flavors or mixed flavors, and can remove the first suction structure from the host 100 and replace it with the second suction structure, the second suction structure has a second smoke cartridge 300 and an oil storage tank 400, and the second oil storage cavity 301 of the second smoke cartridge 300 is connected to the oil storage tank 400 to increase the oil storage capacity of the second suction structure and increase the number of puffs.

[0067] Specifically, in order to allow the second cigarette cartridge 300 to be reused, a second oil filling port 402 is provided on the oil storage box 400 .

[0068] Specifically, in this embodiment, the structure of the second cartridge 300 is the same as the internal structure of the first cartridge 200, except that a communication port connected to the oil storage tank 400 is provided on the outer wall of the second cartridge 300. In other embodiments, the second cartridge 300 may also be a structure of other forms, which only needs to be able to store and atomize the oil.

[0069] Similarly, the first cover plate 215 may also be disposed at the position corresponding to the second oil filling port 402 to open or close the second oil filling port 402 .

[0070] In order to facilitate fixing the first suction structure or the second suction structure, refer to Figure 2 and Figure 8 A card plate 120 is formed on the main unit 100, and the card plate 120 separates the two installation slots 110. When the two first cigarette cartridges 200 are inserted into the installation slots 110, the card plate 120 separates the two first cigarette cartridges 200 to prevent the first cigarette cartridges 200 from being squeezed against each other and damaged. Similarly, when the second cigarette cartridge 300 and the oil storage tank 400 are inserted, the card plate 120 separates the second cigarette cartridge 300 and the oil storage tank 400.

[0071] In some embodiments, reference Figure 8The second cigarette cartridge 300 and the oil storage tank 400 are designed as one body. In order to prevent the card plate 120 from affecting the insertion of the second suction structure, a card slot 403 is formed between the second cigarette cartridge 300 and the oil storage tank 400. The card slot 403 is engaged with the card plate 120, which ensures that the second suction structure can be inserted and improves the installation stability.

[0072] It should also be understood that in some other embodiments, the second cigarette cartridge 300 and the oil storage tank 400 may also be a detachable split design.

[0073] In addition, refer to 2 and Figure 8 The first suction structure and the second suction structure can be provided with a first magnet 260 on one side for inserting into the installation slot 110. For example, the first cartridge 200, the second cartridge 300 and the bottom of the oil storage tank 400 are provided with a first magnet 260. The second magnet 160 is correspondingly provided in the installation slot 110, and the first suction structure and the second suction structure are stably connected to the host 100 through the adsorption of the first magnet 260 and the second magnet 160.

[0074] Regarding the electrical connection method between the host 100 and the first cigarette cartridge 200, a power supply 130 is provided in the host 100, and two symmetrically arranged first power connection parts 140 are provided at the bottom of the mounting groove 110. The two first power connection parts 140 are symmetrically arranged at the bottom of the mounting groove 110, and two symmetrically arranged second power connection parts 250 are provided at the bottom of the first cigarette cartridge 200. The power supply 130 is electrically connected to the first power connection part 140, the first power connection part 140 can be electrically connected to any second power connection part 250, and the second power connection part 250 is electrically connected to the heating structure.

[0075] It is understandable that when the first cigarette cartridge 200 is inserted into the mounting groove 110, the second power connection part 250 on the first cigarette cartridge 200 contacts the first power connection part 140, and the power supply 130 can supply power to the heating structure through the first power connection part 140 and the second power connection part 250. It should be understood that since the two first power connections 140 are symmetrically arranged at the bottom of the mounting groove 110, that is, the two first power connections 140 are symmetrically arranged with the center of the bottom of the mounting groove 110, and the two second power connections 250 are symmetrically arranged at the bottom of the first cigarette cartridge 200, that is, the two second power connections 250 are symmetrically arranged with the center of the bottom of the first cigarette cartridge 200, so that when the first cigarette cartridge 200 is in the forward state or the reverse state, the power supply 130 can keep supplying power to the first cigarette cartridge 200.

[0076] It should be noted that in some usage environments, the carrier of the electronic cigarette of the present application may enter a high-temperature indoor environment from a low-temperature outdoor environment, or other carriers may undergo a scenario of heat exchange. The air pressure in the first oil storage chamber 211 may change due to the temperature difference, and the oil in the first oil storage chamber 211 may leak too much from the oil outlet 222, which may then cause the first cartridge 200 to leak oil.

[0077] In order to reduce the impact of temperature difference, in this embodiment, refer to Fig. 9 A sealed chamber 217 is formed in the housing, and the sealed chamber 217 is connected to the first oil storage chamber 211 through a pipe 290. It should be understood that when the air pressure in the first oil storage chamber 211 changes, the smoke oil in the first oil storage chamber 211 enters the sealed chamber 217 through the pipe 290, reducing the risk of the smoke oil leaking from the oil outlet 222. After the air pressure is restored, the smoke oil in the sealed chamber 217 can be sucked back into the first oil storage chamber 211 through the pipe 290.

[0078] To charge the power source 130, refer to Figure 3 The host 100 is provided with a power supply module 150, which is electrically connected to the power supply 130 and is used to supply power to the power supply 130. The power supply module 150 includes one or both of a wired charging structure 152 and a wireless charging structure 151. For example, the power supply module 150 includes both the wired charging structure 152 and the wireless charging structure 151, so that wired charging can be achieved by connecting the wired charging structure 152 to an external electrical interface through a wire, and wireless charging can also be achieved through a wireless charger outside the wireless charging structure 151. In other embodiments, only one of the wired charging structure 152 and the wireless charging structure 151 may be included.

[0079] Specifically, refer to Figure 3 The receiving coil of the wireless charging structure 151 is planar to reduce the space it occupies. A magnetic isolation sheet is provided at the bottom of the receiving coil, and the shell of the receiving coil is made of non-metallic material.

[0080] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
