[0039] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0040] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various implementations, and the operational steps involved in each embodiment may be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0041] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0042] The atomizer device usually consists of a liquid storage tank and an atomizer core assembly. The liquid storage tank is provided with a liquid storage chamber for storing the atomizer matrix. The atomizer core assembly is installed inside the liquid storage chamber. The atomizer core assembly is also provided with an atomizer channel. An air path bracket is also provided below the liquid storage tank. The air path bracket is provided with at least one sensing air path, which is connected to the atomizer channel. In addition, an air flow sensor is installed on the air path bracket. When using this atomizer device, the user causes the air flow to flow through the sensing channel to the atomizer channel by suction. During the suction process, the air flow sensor can sense the changes in air pressure flowing through the sensing channel, thereby controlling the operation of the atomizer core assembly.

[0043] In the above-mentioned atomizer device, the air path bracket occupies a large space, resulting in a larger overall volume of the atomizer device product, which is inconvenient for users to use, thereby affecting the user experience.

[0044] In response to the above problems, the present application provides an atomization device, in which the airway components are installed in an installation groove at the bottom of the liquid storage tank in an embedded manner, thereby reducing the layout space of the airway components, thereby reducing the overall volume of the atomization device product, facilitating user use, and improving user experience.

[0045] See also Figures 1-13As shown, the atomization device 100 provided in the present application includes a liquid storage tank 10 , an atomization core assembly 20 , an airway component 30 and an airflow sensor 40 .

[0046] The liquid storage tank 10 is provided with a liquid storage cavity 101 for storing atomized substrate, wherein the atomized substrate can be heated to generate aerosol by the atomizing core assembly 20. One end of the liquid storage tank 10 is provided with a mounting groove 121, which is in communication with the liquid storage cavity 101.

[0047] The atomizer core assembly 20 is disposed inside the liquid storage chamber 101 . The atomizer core assembly is formed with an atomizer channel 211 . The atomizer channel 211 is communicated with the mounting groove 121 .

[0048] In this embodiment, a liquid storage member 102 is provided inside the liquid storage cavity 101 . The liquid storage member 102 is made of fiber cotton material. The atomized matrix is ​​usually in liquid form and can be stored in the liquid storage member 102 by adsorption.

[0049] In one embodiment, an aerosol channel 1021 may be provided in the liquid storage member 102 , and the atomizing core assembly 20 is provided in the aerosol channel 1021 .

[0050] The air channel member 30 is embedded in the interior of the mounting groove 121. Figure 2-Figure 4 、 Figure 6 、 Figure 7 as well as Figure 10-12 As shown, the air channel member 30 is further provided with an air intake channel 32 and a sensing channel 33 penetrating therethrough, and the air intake channel 32 and the sensing channel 33 are in communication with the atomization channel 211 .

[0051] When the user uses the atomizer device, the external atmosphere can enter the atomizer channel 211 through the air inlet channel 32, and due to the flow of gas, a negative pressure is generated in the sensing channel 33. The airflow sensor 40 is arranged on the airway component 30. The airflow sensor 40 is used to sense the changes in the air pressure signal of the sensing channel 33 and output an electrical signal to the atomizer device 100 to control the operation of the atomizer core assembly 20, so as to heat the atomizer matrix to generate aerosol, and the aerosol is output through the aerosol channel 1021.

[0052] During the aerosol output process, condensation can easily cause backflow, and the condensed liquid or incompletely atomized atomized matrix can flow back through the atomization channel 211. In the atomization device of the related art, at least the atomization channel 211 and the air inlet channel 32 are set to be coaxial, which causes the aerosol to flow back through the air inlet channel 32 to the outer surface of the atomization device 100, affecting the product appearance. Based on this, in this embodiment, the air inlet channel 32, the sensing channel 33, and the atomization channel 211 are offset from each other in the axial direction, so that the condensed liquid or incompletely atomized atomized matrix will not flow back into the air inlet channel 32 and the sensing channel 33.

[0053] In the above embodiment, the air duct member 30 provided with the air inlet channel 32 and the sensing channel 33 is installed in the installation groove 121 at one end of the liquid storage tank 10, which can save the installation space of the air path structure, thereby reducing the internal structure layout space of the atomization device product, and further reducing the overall volume of the atomization device 100, which is beneficial to user use and thus improves the user experience.

[0054] In this embodiment, the airway member 30 is spaced apart from the bottom of the mounting groove 121 to form an air intake cavity 122, and the air intake cavity 122 is connected to the air intake channel 32, the sensing channel 33 and the atomization channel 211. The external atmosphere enters the air intake cavity 122 after entering through the air intake channel 32, and the air pressure in the sensing channel 33 changes due to the action of the airflow, so that the air pressure signal change is sensed by the airflow sensor 40, thereby controlling the operation of the atomization core assembly 20. The aerosol generated by the operation of the atomization core assembly 20 is output through the atomization channel 211 under the action of the airflow.

[0055] In order to allow the airway member 30 installed in the installation groove 121 to be spaced apart from the bottom of the installation groove 121 to form an air inlet cavity 122, as shown in FIG. Figure 9 As shown, a limiting portion 123 is further provided in the installation groove 121 , and the limiting portion 123 is used to limit the airway component 30 so that an air inlet cavity 122 is formed between the airway component 30 and the bottom of the installation groove 121 .

[0056] In one embodiment, the limiting portion 123 is at least one limiting block 1231 arranged on the bottom and / or side wall of the installation groove 121, and the airway component 30 is pressed against the limiting block 1231 on the side facing away from the accommodating groove 31, so that an air inlet cavity 122 is formed between the airway component 30 and the bottom of the installation groove 121.

[0057] In this embodiment, two limiting blocks 1231 are provided between the bottom and / or side walls of the installation groove 121 to form a stable support for the airway component 30 .

[0058] In order to facilitate the mutual dislocation of the air inlet channel 32, the sensing channel 33 and the atomizing channel 211 in the axial direction, see Figure 9 As shown, the air inlet cavity 122 has a first space 1221 and a second space 1222 that are connected, wherein the first space 1221 is arranged at a position corresponding to the atomization channel 211 and is connected to the atomization channel 211, and the second space 1222 is arranged at a position corresponding to the air inlet channel 32 and the sensing channel 33, and is connected to the air inlet channel 32 and the sensing channel 33, thereby forming the air inlet cavity 122 into an irregular structure.

[0059] In this embodiment, the shape of the mounting groove 121 is the same as that of the air inlet cavity 122. In order to adapt to the shape, since the atomizing channel 211, the air inlet channel 32 and the sensing channel 33 are in a state of different axes, in order to prevent the atomizing channel 211 from being connected to the outside through the mounting groove 121, as shown in FIG. Figure 6 、 Figure 7 ,and Figure 10-12 As shown, the airway member 30 includes a main body 34 and a protrusion 35. The protrusion 35 is provided on the circumference of the main body 34. The air inlet channel 32 and the sensing channel 33 are provided through the main body 34 along the thickness direction of the main body 34. A first space 1221 is formed between the main body 34 and the bottom of the mounting groove 121. A second space 122 is formed between the protrusion 35 and the air inlet end of the atomizing channel 211. The protrusion 35 can block the atomizing channel 211.

[0060] like Figure 3 、 Figure 7 as well as Figure 11 As shown, the airway member 30 is provided with a receiving groove 31 on the side facing away from the mounting groove 121, and the airflow sensor 40 is installed in the receiving groove 31. Figure 2-Figure 4 、 Figure 6 、 Figure 7 as well as Figure 10-12 As shown, the sensing channel 33 is communicated with the accommodating groove 31 , which means that the sensing channel 33 is communicated with the airflow sensor 40 .

[0061] In this way, the condensate generated by the aerosol condensation or the incompletely atomized atomized matrix will flow back into the air inlet chamber 122 through the atomization channel 211. In the related art, the refluxed condensate or the incompletely atomized atomized matrix can flow back toward the airflow sensor 40 through the sensing channel 33, causing corrosion and other damage to the airflow sensor 40. To avoid this problem, in this embodiment, a first guide post 331 is provided on the side of the airway member 30 facing the mounting groove 121. The sensing channel 33 is formed inside the first guide post 331. The first guide post 331 is a columnar structure that protrudes from the side of the airway member 30 facing the mounting groove 121 toward the bottom of the mounting groove 121. Since the first guide post 331 is a structure that protrudes from the airway member 30, the condensate or the incompletely atomized atomized matrix can be collected in the air inlet chamber 122.

[0062] Accordingly, condensed liquid or incompletely atomized atomized substrate, after flowing back through the air inlet passage 32, will flow through the air guide holes 531 onto the outer surface of the atomizing device 100, thereby affecting the aesthetic appearance of the product. Therefore, a second guide post 321 is provided on the side of the airway member 30 facing the mounting groove 121. The air inlet passage 32 is formed inside the second guide post 321. Similarly, since the second guide post 321 is a columnar structure protruding from the side of the airway member 30 facing the mounting groove 121, condensed liquid or incompletely atomized atomized substrate can be collected in the air inlet cavity 122.

[0063] When the amount of condensed liquid or incompletely atomized atomized matrix in the air inlet cavity 122 is large, in order to further prevent it from flowing back to the air flow sensor 40 through the sensing channel 33, as shown in FIG. Figure 6 As shown, on the side of the air duct member 30 facing the mounting groove 121, a first guide post 331 is provided to protrude from the air duct member 30 at a height higher than a second guide post 321 protruding from the air duct member 30. Even if the amount of reflux condensate or incompletely atomized atomized matrix is ​​sufficient to exceed the height of the second guide post 321, it will only flow back from the air guide hole 531 to the outer surface of the atomizing device through the second guide post 321, and will not affect the normal use of the airflow sensor 40.

[0064] In actual use, the amount of backflowing condensate or incompletely atomized atomized matrix is ​​very small, and the purpose of providing the first guide pillar 331 and the second guide pillar 321 is to prevent it from backflowing through the sensing channel 33 or the air inlet channel 32.

[0065] In some embodiments, the height of the first guide pillar 331 and the height of the second guide pillar 321 are both lower than the height of the air inlet cavity 122 , so that the first guide pillar 331 and the second guide pillar 321 can maintain communication with the air inlet cavity 122 .

[0066] In this embodiment, the height of the first guide pillar 331 and the height of the second guide pillar 321 are both higher than the height of the air inlet cavity 122. In order to ensure that the first guide pillar 331 and the second guide pillar 321 can maintain a state of communication with the air inlet cavity 122, as shown in FIG. Figure 2 、 Figure 4 、 Figure 9 and Figure 11 As shown, a first avoidance groove 1211 is provided on the side of the mounting groove 121 facing the first guide post 331 to prevent the first guide post 331 from being away from one end of the airway member 30. A second avoidance groove 1222 is provided on the side of the mounting groove 121 facing the second guide post 321 to prevent the second guide post 321 from being away from one end of the airway member 30.

[0067] In this embodiment, the liquid storage tank 10 includes a tank body 11 and a first sealing member 12. One end of the tank body 10 has an opening, and the first sealing member 12 is sealingly connected to the opening of the tank body 11, so that the first sealing member 12 and the tank body 11 enclose a liquid storage chamber 101. A mounting groove 121 is formed on a side of the first sealing member 12 that faces away from the liquid storage chamber 101, and at least a portion of the groove wall of the mounting groove 121 is arranged around the air inlet end of the atomization channel 211.

[0068] In one embodiment, the liquid storage tank 10 also includes a second seal 13, and the other end of the tank body 11 also has an opening. The second seal 13 is sealed and connected to the opening at the other end of the tank body 11. The space enclosed by the tank body 11, the first seal 12 and the second seal 132 forms a liquid storage chamber 101.

[0069] The atomization device provided in this embodiment also includes a shell component 50 and a mounting bracket 60, wherein the interior of the shell component 50 has a receiving cavity 501, the liquid storage tank 20 and the mounting bracket 60 are both arranged inside the receiving cavity 501, and the liquid storage tank 20 is installed on the mounting bracket 60.

[0070] In one embodiment, the housing assembly 50 defines an air guide hole 531 communicating with the receiving cavity 501 . The air guide hole 531 communicates with the interior of the receiving cavity 501 , thereby allowing the external atmosphere to communicate with the receiving cavity 501 .

[0071] The air guide hole 531 connects the receiving chamber 501 of the housing assembly 50 with the external atmosphere. To facilitate user use, the housing assembly 50 is further provided with a suction nozzle 521, which is provided with a suction nozzle channel 522. One end of the air inlet channel 32 can be connected to the air guide hole 531, and the other end of the air inlet channel 32 is connected to the atomization channel 211. The atomization channel 211 is located inside the aerosol channel 1021. Moreover, since the aerosol channel 1021 can extend to the outside of the housing assembly 50 through the suction nozzle channel 522 of the suction nozzle 521, the user can inhale through the suction nozzle 521, and the external atmosphere can enter the air inlet channel 32 through the air guide hole 531.

[0072] In the related art, since the air duct member 30 has a certain distance between the air guide holes 531 to form a larger space, when the user is inhaling, the external air enters the space through the air guide holes 531 and easily generates vortexes, thereby generating a certain suction resistance and affecting the user experience.

[0073] like Figure 2-Figure 4 As shown, in this embodiment, an air inlet column 61 is provided on the mounting bracket 60, Figure 5 as well as Figure 13 As shown, the air inlet column 61 has an air inlet hole 611 extending through the interior thereof along its axial direction, with one end of the air inlet hole 611 facing the air guide hole 531. The end of the second guide column 321 away from the mounting groove 121 is inserted into the interior of the air inlet column 61, so that the air inlet channel 32 is connected to the air inlet hole 611.

[0074] In the above embodiment, the air guide hole 531 is guided to communicate with the air intake channel 32 through the air intake column 61, which can shorten the length of the air flow and thus avoid the generation of vortex phenomenon.

[0075] In a specific embodiment, the shell assembly 50 includes a main shell 51, an upper cover 52 and a lower cover 53. The main shell 51 is a cylindrical structure with a hollow interior and open ends. The upper cover 52 and the lower cover 53 are respectively connected to the open ends of the main shell 51, so that the main shell 51, the upper cover 52 and the lower cover 53 form a receiving cavity 501, wherein the air guide hole 531 is set on the lower cover 53.

[0076] In one embodiment, the atomizing device 100 allows external air to enter the interior of the receiving chamber 501 through the air guide hole 531 by suction. Therefore, a suction nozzle 521 is further provided on the upper cover 52, and the suction nozzle 521 can facilitate the user to perform suction.

[0077] In some embodiments, in order to facilitate the user to suck through the nozzle 521, as shown in FIG. Figure 3 As shown, a nozzle channel 522 is further provided inside the nozzle 521 , and during the suction process, external air can drive the aerosol to be output from the nozzle 521 through the nozzle channel 522 .

[0078] The atomizing core assembly 20 can heat the atomizing matrix to generate aerosol, and the generated aerosol can be output through the mouthpiece 521 for use by the user.

[0079] One end of the liquid storage tank 10 is the first sealing member 12, wherein the mounting groove 121 is provided on the side of the first sealing member 12 facing the mounting bracket 60, and the atomization channel 211 is provided on the side of the first sealing member 12 facing the liquid storage member 102. An aerosol channel 1021 is provided inside the liquid storage member 102, see Figure 5 as well as Figure 8 As shown, the atomization channel 211 extends toward the liquid storage component 102 and protrudes from the first sealing component 12. After the first sealing component 12 is installed at the opening at the lower end of the liquid storage tank 10, the atomization channel 211 is inserted into the aerosol channel 1021.

[0080] Continue to see Figure 3 As shown, the atomizer core assembly 20 includes an atomizer tube 21, a liquid guide (not shown in the figure) and a heater (not shown in the figure), wherein the atomizer tube 21 is arranged in the aerosol channel 1021 of the liquid storage part 102, and the atomizer tube 21 is connected to the nozzle channel 522 after passing through the second sealing part 13. The aforementioned atomizer channel 211 is inserted into the interior of the atomizer 321, and a connecting port 212 is provided on the atomizer tube 21. The liquid guide is installed in the interior of the atomizer tube 21 and extends to the outside of the atomizer tube 21 through the connecting port 212 to contact the liquid storage part 102, so that the atomized matrix stored in the liquid storage part 102 can be conducted to the heater. The heater is wrapped around the portion of the liquid guide located inside the atomizer tube 21, and the heater can heat the atomized matrix to generate an aerosol.

[0081] When the product leaves the factory, in order to prevent debris from entering the product through the nozzle channel 522 and affecting the normal use of the product, a blocking member 523 is further provided at the nozzle channel 522. During the storage and transportation of the atomizing device 100, the blocking member 523 blocks the nozzle channel 522.

[0082] As mentioned above, one end of the air inlet hole 611 of the air inlet column 61 faces the air guide hole 531 and is connected to the air guide hole 531, while the other end of the air inlet hole 611 is connected to the air inlet channel 32. Figure 3 As shown, when the user inhales through the nozzle 521, an environment with a lower pressure than the external air is formed in the nozzle channel 522, the atomizing tube 21, the atomizing channel 211, the air inlet cavity 122, the air inlet channel 32, and the air inlet hole 611. The external air can flow in the direction of the air guide hole 531, the air inlet hole 611, the air inlet channel 32, the air inlet cavity 122, the atomizing channel 211, the atomizing tube 21, and the nozzle channel 522. In this way, the flowing air forms a negative pressure inside the receiving tank 31 through the sensing channel 42. After the air flow sensor 40 senses the air pressure change, it can generate a control signal.

[0083] It should be noted that the airflow sensor 40 is electrically connected to the heater in the atomizer core assembly 20. Control signals control the heater to heat the atomized matrix conducted by the liquid guide, generating aerosol particles. The generated aerosol particles then flow with the airflow through the atomizer tube 21 and the nozzle channel 522, and are then output through the nozzle 521 for the user.

[0084] When the user stops inhaling, since there is no airflow, the airflow sensor 40 cannot sense the air pressure change, and the heating element is controlled to stop working.

[0085] In the present application, the air inlet channel 32 on the air duct component 30 is kept in communication with the air inlet hole 611 in the air inlet column 61 of the mounting bracket 60, so that the airflow entering from the outside can directly enter the air inlet channel through the air inlet hole 611, thereby avoiding the generation of vortexes in the space between the liquid storage tank 10 and the lower cover 53.

[0086] At the same time, an air inlet channel 32 and a sensing channel 33 are separately provided on the airway member 30, with only the sensing channel 33 communicating with the receiving groove 31. After the airway member 30 is installed in the mounting groove 121, the atomizing channel 211, the air inlet channel 32, and the sensing channel 33 are offset from one another. This prevents condensed liquid or incompletely atomized atomized matrix from flowing directly back through the sensing channel 33 to the airflow sensor 40, and prevents it from flowing back through the air inlet channel 32 to the air guide hole 531. This not only extends the service life of the atomizing device, but also ensures the aesthetics of its exterior surface.

[0087] In this embodiment, in order to further reduce the condensate backflow, Figure 2-Figure 5 As shown, a liquid absorbing member 5211 is provided between the suction nozzle 521 and the second sealing member 13 to absorb the reverse-flowing condensate.

[0088] In the present application, the heating element in the atomizer core assembly 20 is driven for heating by electric energy. The atomizer device 100 provided in the present application also includes a battery 70 and a circuit board 80. The battery 70 and the circuit board 80 are arranged in the accommodating cavity 501. The output end of the circuit board 80 is electrically connected to the heating element, and the input end is electrically connected to the battery 70, so as to power the heating element through the circuit board 80.

[0089] In this embodiment, the battery 70 and the liquid storage tank 10 are mounted side by side on the mounting bracket 60. Figure 13 As shown, the mounting bracket 60 is further provided with a slot 63, into which the battery 70 is inserted. The circuit board 80 is disposed between the liquid reservoir 10 and the mounting bracket 60. The mounting bracket 60 is located above and adjacent to the lower cover 53. One end of the air inlet 611 is disposed toward the air guide hole 531, shortening the distance between the air guide hole 531 and the air inlet 611. When a user inhales through the suction nozzle 521, external air can quickly enter the air inlet 611 through the air guide hole 531, thereby preventing the air from entering the receiving chamber 501 from generating vortexes.

[0090] In specific embodiments, see Figure 3 、 Figure 8 、 Figure 9 as well as Figure 11 As shown, the circuit board 80 is arranged on the side of the airway member 30 facing away from the mounting groove 121, and cooperates with the airway member 30 to seal the receiving groove 31. A conductive electrode 81 is provided on the side of the circuit board 80 facing away from the liquid storage tank 10, as shown in FIG. Figure 13 As shown, the mounting bracket 60 is provided with a third guide column 62 , and the third guide column 62 is provided with a communication hole 621 . The conductive electrode 81 is passed through the communication hole 621 , and the conductive electrode 81 is electrically connected to the battery 70 .

[0091] like Figure 3 As shown, the atomization device 100 provided in this embodiment further includes a conductive member 82, which is fixed on the lower cover 13, and the two ends of the conductive member 82 respectively abut against the conductive electrode 81 and the battery 70, and the conductive member 82 is electrically connected to the conductive electrode 81 and the battery 70, thereby electrically connecting the conductive electrode 81 to the battery 70.

[0092] The first sealing member 12 of the liquid storage tank 10 is further provided with a first pin mounting hole 124 and a second pin mounting hole 125. The first pin mounting hole 124 is used to mount a first pin electrically connected to the heater in the atomizer core assembly 20, and the second pin mounting hole 125 is used to mount a second pin connected to the conductive electrode 81. After the first pin and the second pin are electrically connected, the conductive electrode 81 can be electrically connected to the heater, thereby providing electrical energy to the heater through the battery 70. In this embodiment, two first pin mounting holes 124 are provided on one side of the first sealing member 12, and two second pin mounting holes 125 are provided on the other side of the first sealing member 12, corresponding to the positive and negative poles of the battery 70, respectively.

[0093] To facilitate the connection between the conductive electrode 81 and the second pin, in this embodiment, the conductive electrode 81 passes through the circuit board 80 , and a third avoidance groove 1213 is further provided on the first sealing member 12 to avoid the conductive electrode 81 .

[0094] like Figure 5 As shown, a avoidance hole 83 is further provided on the circuit board 80 to avoid the second guide column 321 from being away from one end of the mounting groove 121 , so that the second guide column 321 can be connected to the air inlet hole 611 of the air inlet column 61 through the avoidance hole 83 .

[0095] like Figure 4 As shown, the end of the second guide column 321 away from the installation groove 121 is inserted into the air inlet hole 611 of the air inlet column 61, and the outer diameter of the third air guide column 422 is smaller than the inner diameter of the air inlet column 61, that is, smaller than the aperture of the air inlet hole 611.

[0096] To sum up, in the atomizer device provided in the present application, the air duct components for the air inlet channel and the sensing channel are installed in the mounting groove at one end of the liquid storage tank, which can save the setting space of the air path structure, thereby reducing the internal structure layout space of the atomizer product, and further reducing the overall volume of the atomizer device, which is beneficial to user use and thus improves the user experience.

[0097] The air inlet channel on the airway component is kept in communication with the air inlet hole in the air inlet column of the mounting bracket, so that the airflow entering from the outside can directly enter the air inlet channel through the air inlet hole, which can avoid the airflow from generating vortexes in the space between the liquid storage tank and the lower cover. At the same time, an air inlet channel and a sensing channel are respectively provided on the airway component, and only the sensing channel is connected to the receiving groove. After the airway component is installed in the mounting groove of the bracket, the atomization channel, the air inlet channel and the sensing channel are dislocated from each other. In this way, the condensate generated by the condensation of the aerosol or the atomized matrix that is not completely atomized will not directly flow back to the airflow sensor through the sensing channel, and will not flow back to the mounting groove through the air inlet channel. While extending the service life of the atomization device, the aesthetics of the outer surface of the atomization device can also be ensured.

[0098] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
