[0038] An embodiment of the present application provides a paste atomization device, which is used to heat an atomization medium (such as tobacco paste or tobacco liquid) inside thereof to form an aerosol for a user to inhale.

[0039] The following uses an electronic atomization device for heating solid cigarette paste to generate an aerosol as an example of a paste atomization device to illustrate the structure of the paste atomization device in the present application. This embodiment is only used as an example and does not limit the technical scope of the present application. It can be understood that in other embodiments, the paste atomization device of the present application is not limited to the above-mentioned electronic atomization device for heating solid cigarette paste, but can also be other paste atomization devices for heating a solid atomization medium to generate an aerosol, which is not limited here.

[0040] See Figures 1 to Figure 4 , FIG. 1 and FIG. 2 show the appearance schematic diagram of the paste atomization device 10 in one embodiment of the present application, Figure 3 FIG. 1 shows an exploded schematic diagram of the paste atomization device 10 in this embodiment. Figure 4 A cross-sectional view of the internal structure of the paste atomization device 10 in this embodiment is shown.

[0041] Specifically, see Figure 3 and Figure 4The housing 100 has a housing chamber 103, and the housing 100 is provided with a mounting groove 104 that runs through the opposite sides of the housing 100, the mounting groove 104 and the housing chamber 103 are isolated from each other, and an air outlet 101 is provided at one end of the housing 100, the mounting groove 104 is provided at the end of the housing 100 away from the air outlet 101, and the groove wall of the mounting groove 104 is provided with an air through hole 102 that is connected to the air outlet 101. The atomization unit 200 is detachably fixedly inserted in the mounting groove 104, and the atomization unit 200 has an atomization chamber 203, and the atomization chamber 203 is provided with an atomization core 230 that is electrically connected to the power supply unit 300. The atomization unit 200 is also provided with an air inlet 201 and an air vent 202 that are interconnected through the atomization chamber 203, and the air inlet 201, the air vent 202, the air through hole 102, and the air outlet 101 are connected in sequence. The power supply unit 300 is used to supply power to the atomization unit 200. When the power supply unit 300 supplies power to the atomization unit 200, the atomization core 230 can heat the atomization medium contained in the atomization chamber 203 to generate aerosol, which is then discharged through the vent hole 202, the air hole 102 and the air outlet hole 101 in sequence.

[0042] In some embodiments, the atomization unit 200 can be detachably fixed and inserted in the mounting groove 104 by means of magnetic attraction, or can be detachably fixed and inserted in the mounting groove 104 by means of a buckle 106 connection. Specifically, with respect to the connection structure of the buckle 106 connection, one of the outer wall of the atomization unit 200 and the groove wall of the mounting groove 104 is provided with a buckle 106, and the other is provided with a slot 204 corresponding to the buckle 106, and the buckle 106 is snapped into the slot 204, so that the atomization unit 200 can be fixedly inserted in the mounting groove 104. Compared with the magnetic attraction fixing method, it can avoid the atomization unit 200 being difficult to disassemble due to too strong magnetism, and it can also avoid the atomization unit 200 being easy to fall off from the mounting groove 104 due to insufficient magnetism, and at the same time, it can avoid the problems of increased cost and increased device volume caused by setting a magnetic attraction structure, so it has a better technical effect.

[0043] In this way, when the atomizing medium in the atomizing unit 200 is exhausted or the atomizing unit 200 fails, the user can easily replace the atomizing unit 200, so that it is convenient for the user to use, and it can also reduce the risk of the whole machine being scrapped due to local damage to electronic components, extend the life of the product, and reduce environmental pollution and waste of resources. Furthermore, since the installation groove 104 runs through the opposite sides of the shell 100, when the user removes the atomizing unit 200, he only needs to use his fingers to push the atomizing unit 200 along the axial direction of the installation groove 104, and the atomizing unit 200 can be easily removed from the shell 100, which is convenient for the user's operation and greatly improves the user's experience.

[0044] Furthermore, in order to prevent the user from inserting the atomizer unit 200 into the mounting groove 104 in the reverse direction, that is, to ensure that the atomizer unit 200 can only be inserted into the mounting groove 104 at one of the two ends of the mounting groove 104 along its own axial direction, the two ends of the mounting groove 104 in its own axial direction are respectively defined as a limit end and a mounting end, and the opening inner diameter of the mounting end is larger than the opening inner diameter of the limit end, so that the atomizer unit 200 can only be inserted into the mounting groove 104 from the mounting end, thereby preventing the atomizer unit from being inserted in the reverse direction.

[0045] Exemplarily, a limiting structure extending toward the mounting groove may be provided at the opening edge of the limiting end, such as a protrusion or rib extending from the opening edge of the limiting end toward the center of the mounting groove 104; the inner circumferential surface of the mounting groove 104 may also be provided as a structure extending obliquely along the axial direction of the mounting groove 104, both of which can achieve that the inner diameter of the opening of the mounting end is larger than the inner diameter of the opening of the limiting end, which is not limited here.

[0046] Furthermore, in order to prevent the atomizing unit 200 from rotating and thus being misaligned when inserted into the mounting groove 104, refer to Figure 3 , the outer circumference of the atomizing unit 200 includes a first plane 205, and the vent hole 202 is provided on the first plane 205; correspondingly, the groove wall of the mounting groove 104 includes a second plane 104a that fits the first plane 205, and the vent hole 102 is provided on the second plane 104a, and the groove wall profile of the mounting groove 104 matches the outer circumference profile of the portion of the atomizing unit 200 inserted in the mounting groove 104. In the embodiment shown in the figure, the outer circumference of the portion of the atomizing unit 200 inserted in the mounting groove 104 has a plane, namely the first plane 205, and the rest are arc surfaces. Correspondingly, the groove wall of the mounting groove 104 also has a plane, namely the second plane 104a, and the rest are also arc surfaces, so that when the atomizing unit 200 is inserted into the mounting groove 104, there is only one installation direction in its own circumferential direction, thereby preventing the atomizing unit 200 from rotating and thus dislocating when inserted in the mounting groove 104.

[0047] Of course, it is understandable that the groove wall contour of the mounting groove 104 and the outer peripheral surface contour of the part of the atomization unit 200 inserted in the mounting groove 104 are not limited to the shapes shown in the embodiment of the figure, as long as they have a plane so that the atomization unit 200 cannot rotate after being inserted into the mounting groove 104.

[0048] See also Figure 5In one embodiment, a suction nozzle 105 is provided at the top of the shell 100, and an air outlet 101 passes through opposite ends of the suction nozzle 105. The air outlet 101 and the air hole 102 are coaxially arranged at intervals. A ventilation pipe 400 is provided in the accommodating cavity 103. The ventilation pipe 400 is provided with a main air channel 401 passing through opposite ends thereof, and the air hole 102 and the air outlet 101 are connected to each other through the main air channel 401. In the installation method of the ventilation tube 400, a first sealing member 500 made of silicone is provided at a position near the suction nozzle 105 in the accommodating cavity 103, and a second sealing member 600 made of silicone is also provided in the accommodating cavity 103. The first sealing member 500 and the second sealing member 600 are arranged relatively spaced apart, the suction nozzle 105 is inserted at one side of the first sealing member 500, one end of the ventilation tube 400 is inserted at a side of the first sealing member 500 facing away from the suction nozzle 105, and the other end of the ventilation tube 400 is inserted at the second sealing member 600. The first sealing member 500 is used to prevent the condensate generated by the aerosol from flowing back from the suction nozzle 105 into the shell 100 and causing a short circuit in the power supply unit 300, and the second sealing member 600 is used to prevent the condensate in the ventilation tube 400 from flowing back into the atomization unit 200.

[0049] In this way, by setting a straight vent pipe 400, one end of which is connected to the air outlet 101, and the other end of which is connected to the mounting groove 104 through the air hole 102, there are no other components in the vent pipe 400. Compared with the structure in which the atomizing core 230 in the existing paste atomizing device 10 is usually required to be arranged in the vent pipe 400, this structure makes it easier for users to clean the condensed substances or other impurities remaining in the main airway 401. Users only need to use a matching straight brush, insert it into the main airway 401 from the air outlet 101 at the suction nozzle 105, and they can directly penetrate the entire main airway 401, clean out all impurities in the airway from the air hole 102, and there will be no residual impurities. The cleaning effect is very good, and there is no need to disassemble separate parts for cleaning, and the cleaning operation is very convenient.

[0050] See also Figure 4 and Figure 5 In the embodiment shown in the figure, the power supply unit 300 includes a battery 310 and a circuit board 320. The battery 310 is disposed on one side of the circuit board 320 and is electrically connected to the circuit board 320. The circuit board 320 is sleeved and clamped on the outer wall of the mounting groove 104 to be fixed in the accommodating cavity 103 of the housing 100. The circuit board 320 is provided with at least two electrodes 321, see Figure 6 The atomization unit 200 has at least two electrode contacts 206 correspondingly, and each electrode 321 is electrically connected to a corresponding electrode contact 206. In this embodiment, there are three electrodes 321 and three electrode contacts 206, respectively. Each electrode 321 abuts against a corresponding electrode contact 206, thereby achieving electrical connection between the power supply unit 300 and the atomization unit 200.

[0051] It should be noted that among all the electrodes 321, one electrode 321 is a positive electrode, another electrode 321 is a negative electrode, and the remaining electrodes 321 can be used for information reading, writing, collection, and interaction between the atomization unit 200 and the power supply unit 300. For example, in this embodiment, there are three electrodes 321, and except for the two electrodes 321 used as the positive electrode and the negative electrode, the remaining electrode 321 can be used to read the information in the chip, circuit or sampling resistor in the atomization unit 200, so that the circuit board 320 in the power supply unit 300 can match different heating modes according to different atomization units 200 control.

[0052] See also Figure 4 In the specific structure of the atomizing unit 200, the atomizing unit 200 includes a main body 210 and a heating pot 220, the atomizing chamber 203 is opened in the main body 210, and the heating pot 220 is coaxially arranged in the atomizing chamber 203 and coaxially arranged with the mounting groove 104, such as Figure 7 and Figure 8 As shown, the heating pot 220 has a cavity running through the opposite ends of its axial direction, and the cavity includes a first cavity 221a and a second cavity 222a that are interconnected. The atomizer core 230 is arranged in the first cavity 221a, and the second cavity 222a is used to accommodate the atomization medium. Specifically, the heating pot 220 is a hollow cylindrical metal structure, which includes a first pot body 221 and a second pot body 222 that are coaxially connected and have different diameters. The diameter of the first pot body 221 is smaller than the diameter of the second pot body 222. The first cavity 221a is opened in the first pot body 221, and the second cavity 222a is opened in the second pot body 222. When the atomizer core 230 is powered on to generate heat, the solid atomization medium (such as solid tobacco paste) contained in the second cavity 222a can be melted into a molten state and flow into the atomizer core 230, and can be further heated by the atomizer core 230 to generate an aerosol.

[0053] Furthermore, in order to accelerate the melting of the solid atomizing medium into a molten state, on the basis of the above embodiment, the outer peripheral surface of the second pot body 222 is provided with a preheating member 240 electrically connected to the circuit board 320 of the power supply unit 300, and the preheating member 240 is used to preheat the atomizing medium contained in the second cavity 222a, so that the solid atomizing medium is accelerated to melt and flow into the atomizing core 230, so that the atomizing core 230 can more fully heat the atomizing medium to generate an aerosol.

[0054] In a specific embodiment, the preheating element 240 is an FPC (Flexible Printed Circuit) heating cable, which has excellent flexibility, light weight, thin thickness, good bendability, and can fit tightly to the outer surface of the heating pot 220. When the preheating element 240 is powered on, the heat can be transferred to the second cavity 222a quickly, so that the solid atomization medium in the second cavity 222a can be quickly heated to a molten flow state. The atomization core 230 is made of ceramic material. This is because the ceramic carrier has excellent heat resistance and good oil conduction and oil locking functions. The molten atomization medium can be evenly immersed in it. Once the user starts to inhale, each inhaled smoke can maintain a certain degree of taste consistency, so that the atomization core 230 made of ceramic material can completely release the rich flavor and make the inhalation taste better.

[0055] Please continue reading Figure 7 and Figure 8 In some embodiments, the main body 210 of the atomizing unit 200 includes a box body 211 and a sealing ring 212 connected to each other. The box body 211 is fitted and connected to the groove wall of the installation groove 104. At least part of the sealing ring 212 is inserted into the box body 211. Part of the inner wall of the box body 211 and the inner wall of the sealing ring 212 together form the atomizing chamber 203. The heating pot 220 is inserted into the sealing ring 212. The air inlet 201 is provided on the box body 211. The box body 211 is also provided with a buckle 106 or a card slot 204 for mutually engaging with the groove wall of the installation groove 104. The box body 211 is made of hard plastic and is used to protect the parts in the atomizing unit 200. The sealing ring 212 is made of silicone and is used to seal the atomizing medium and parts in the atomizing unit 200, and is also used to further prevent the condensate in the main airway 401 from flowing back into the atomizing chamber 203.

[0056] Preferably, the air inlet 201 is disposed on the back side of the box body 211 (the side facing the heating pot 220 is the front side). Specifically, the flow direction of the air at the air inlet 201 entering the atomizing chamber 203 is parallel to the axial direction of the mounting slot 104 .

[0057] In other embodiments, the air inlet 201 may also be provided on the side of the box body 211. When the atomizing unit 200 is located in the mounting groove 104, the air inlet 201 faces the side wall of the mounting groove 104. At this time, the external air can flow to the air inlet 201 through the gap between the atomizing unit 200 and the mounting groove 104, and then flow through the inside of the atomizing unit 200. Of course, a through hole can also be provided at the position of the side wall of the mounting groove 104 corresponding to the air inlet 201, so as to allow the external air to enter the atomizing chamber 203. The connection structure between the box body 211 and the sealing ring 212 may be as follows: Figure 7As shown in the embodiment, the sealing ring 212 is completely inserted into the box body 211. At this time, the sealing between the atomizer unit 200 and the shell 100 is performed by the second sealing member 600. In this embodiment, the air hole 102 is opened on the second sealing member 600 and passes through the opposite sides of the second sealing member 600. The second sealing member 600 forms a part of the groove wall of the mounting groove 104. The end of the vent pipe 400 away from the suction nozzle 105 is inserted into the air hole 102 opened by the second sealing member 600. When the atomizer unit 200 is inserted into the mounting groove 104, one side of the second sealing member 600 abuts against the box body 211 of the atomizer unit 200. The air hole 202 is opened on the box body 211, so that the air hole 102 and the air hole 202 are connected to each other.

[0058] In other embodiments, in order to make the paste atomization device 10 of the present application have better connectivity and air tightness, a sealing structure is further provided between the atomization unit 200 and the housing 100. Specifically, the sealing structure is provided between the air hole 102 and the vent hole 202, and is used to seal the connection gap between the groove wall of the installation groove 104 and the box body 211 of the atomization unit 200, so as to prevent the aerosol generated by the heating and atomization of the atomization unit 200 from overflowing from the above connection gap when passing through the vent hole 202 and the air hole 102, thereby affecting the user's inhalation taste.

[0059] In one of the embodiments, the second sealing member 600 slightly protrudes from the side wall of the mounting groove 104 toward the mounting groove 104, that is, the sealing structure is the portion of the second sealing member 600 slightly protruding from the side wall of the mounting groove 104, so that when the atomization unit 200 is inserted into the mounting groove 104, the protruding sealing structure can be used to make the second sealing member 600 more tightly abut against the box body 211 of the atomization unit 200, thereby improving the sealing performance.

[0060] In other embodiments, considering that the atomization unit 200 is a detachable consumable, when the paste atomization device 10 is not in use, or needs to be disassembled or replaced after the atomization medium is exhausted, the atomization unit 200 will often be plugged in and out of the mounting groove 104, so that the box body 211 of the atomization unit 200 will often rub against the second seal 600. After a long time, the sealing performance of the second seal 600 will be reduced due to wear. If the second seal 600 is to be replaced, the shell 100 needs to be disassembled and the second seal 600 and the ventilation pipe 400 need to be disassembled from each other. Therefore, it will be more troublesome to replace the second seal 600.

[0061] To solve the above problems, see Figure 8 and Fig. 9In another preferred embodiment, the second sealing member 600 is in contact with the portion of the shell 100 for forming the mounting groove 104 (i.e., it is in contact with the side of the mounting groove 104 facing the accommodating chamber 103), and the air hole 102 is provided in the portion of the groove wall of the shell 100 for forming the mounting groove 104. The box body 211 is provided with an air inlet 201 and an air groove 2112 that are interconnected, and the air hole 202 is provided on the sealing ring 212. The box body 211 has a slot 2114 connected to the air hole 102, and at least a portion of the sealing ring 212, i.e., at least a portion having the air hole 202, is embedded in the slot 2114, so that the air hole 202 is located between the air groove 2112 and the air hole 102, and is connected to the air groove 2112 and the air hole 102. Specifically, as Fig.10 As shown, the top wall of the box body 211 is provided with a through hole 2113 which passes through the top wall of the box body 211, and the box body 211 also has a plug-in portion 2111, and an air groove 2112 passes through the opposite sides of the plug-in portion 2111, and the groove walls of the mounting groove 104 of the plug-in portion 2111 jointly form the above-mentioned slot 2114, when the portion of the sealing ring 212 provided with the vent hole 202 is embedded in the slot 2114, the portion of the sealing ring 212 provided with the vent hole 202 is exposed from the box body 211.

[0062] Furthermore, combined with Figure 6 and Figure 8 As shown, a sealing ring 213 surrounding the vent 202 is provided on the side of the sealing ring 212 facing away from the plug-in portion 2111, and the sealing ring 213 abuts against the groove wall of the mounting groove 104 (i.e., abuts against the part of the groove wall of the housing 100 that forms the mounting groove 104), and the sealing ring 213 is also the above-mentioned sealing structure arranged between the atomizing unit 200 and the housing 100. In this way, the sealing structure is arranged on the atomizing unit 200, which not only enables the atomizing unit 200 and the groove wall of the mounting groove 104 to form a better seal, but also, even if the atomizing unit 200 often needs to be plugged in and out of the mounting groove 104, resulting in wear of the sealing ring 212 or the sealing ring 213 and resulting in a decrease in sealing performance, the sealing ring 212 can be replaced by the way when the atomizing unit 200 is replaced, so that the second sealing member 600 does not need to be replaced additionally, which facilitates the operation of the user.

[0063] It can be understood that the sealing ring 213 can be integrally connected to the sealing ring 212, or can be detachably connected to the sealing ring 212. When the sealing ring 213 is integrally connected to the sealing ring 212, the atomization unit 200 can be easily assembled as a whole. When the sealing ring 213 is detachably connected to the sealing ring 212, only the sealing ring 213 can be replaced when wear occurs.

[0064] It can also be understood that two sealing rings 212 can be provided, wherein one sealing ring 212 is completely sleeved on the box body 211, and the other sealing ring 212 is inserted into the box body 211, so as to achieve the purpose of not having to additionally replace the second sealing member 600 when the sealing performance between the atomization unit 200 and the housing 100 decreases.

[0065] In the above embodiment, the sealing ring 212 is embedded in the slot 2114 on one side surface to form a first plane 205, and the electrode contact 206 and the vent hole 202 are both arranged on the first plane 205. By arranging the electrode contact 206 on the first plane 205, the electrode 321 can be more tightly contacted with the electrode contact 206, thereby avoiding the occurrence of poor contact.

[0066] Furthermore, in order to ensure that the atomizer unit 200 is inserted into the mounting groove 104 to an appropriate depth and to avoid the atomizer unit 200 being inserted too shallowly or too deeply so as to prevent the air hole 102 from being centered with the air vent 202 or the electrode 321 from being unable to contact the electrode contact 206, the box body 211 has a step 2115 surrounding the central axis of the box body 211, and the step 2115 abuts against one side of the shell 100. The step 2115 is used to limit the atomizer unit 200 so that the atomizer unit 200 can be inserted to a depth at which the air hole 102 is centered with the air vent 202 and the electrode 321 is fully in contact with the electrode contact 206.

[0067] Furthermore, if Figure 4 As shown, one end of the atomizing unit 200 has an opening 207, and the opening 207 faces the second cavity 222a of the heating pot 220. The atomizing medium can be put into the second cavity 222a of the heating pot 220 through the opening 207. An oil tank cover 250 for closing the opening 207 is detachably provided at the position of the opening 207. When the atomizing medium of the paste atomizing device 10 needs to be loaded into the heating pot 220 before leaving the factory, it is only necessary to open the oil tank cover 250, load the solid atomizing medium into the accommodating cavity 103 of the heating pot 220 through the opening 207, and then close the oil tank cover 250.

[0068] In a preferred embodiment, please continue to refer to Figure 4, the central axis of the heating pot 220 is perpendicular to the central axis of the ventilation tube 400 (that is, the central axis of the mounting groove 104 is perpendicular to the central axis of the main airway 401), so that when the paste atomization device 10 is held by the user for horizontal suction (that is, when the opening 207 of the atomization unit 200 is facing upward), the solid atomization medium becomes a molten state that can flow under the preheating effect of the preheating member 240, and the molten atomization medium further generates an aerosol under the heating of the atomization core 230, so that the flow path of the molten atomization medium is in the vertical direction, and the outflow path of the aerosol is in the horizontal direction. In this case, the molten atomization medium can enter the atomization core 230 more smoothly under the action of gravity, so that the atomization medium can be atomized more thoroughly when heated and atomized by the atomization core 230, thereby reducing the residue of the atomization medium and avoiding the blockage of the main airway 401. Moreover, through the above arrangement, the power supply unit 300 can be arranged by fully utilizing the space inside the shell 100 in the flow direction of the atomized medium, making the internal structure of the paste atomization device 10 more compact, thereby achieving the purpose of making the appearance of the paste atomization device 10 more compact and flat.

[0069] In addition, in order to enable the user to conveniently control the working state of the paste atomization device 10, that is, to conveniently control the paste atomization device 10 to switch from the preheating state to the heating state, and from the heating state to the standby state in which the paste atomization device 10 is not working, refer to 2 and Figure 4 The shell 100 is also provided with a button 700 on the side of the opening 207 facing away from the atomization unit 200 for the user to switch between the above working states. The button 700 can move relative to the shell 100 under the action of an external force, so that the button 700 can be connected to the circuit board 320, thereby sequentially driving the circuit board 320 to control the opening and closing of the preheating component 240 and the opening and closing of the atomization core 230 respectively.

[0070] In this way, by arranging the opening 207 of the atomization unit 200 relative to the button 700, the paste atomization device 10 provided in the present application is more user-friendly in design, and the user's operation is more in line with people's operating habits. During operation, the user only needs to hold the shell 100 with his hand, press the button 700 with his thumb, or toggle the button 700 to easily control the paste atomization device 10 to be in a heating state, preheating state or standby state. Compared with the button 700 being set on the same side as the opening 207 of the atomization unit 200 or being set on the side relative to the opening 207 of the atomization unit 200, it is more suitable for user operation. Furthermore, by using the button 700 to control the paste atomization device 10 to switch between the standby state, the preheating state, and the heating state, it is not necessary to set an airflow sensor in the atomization unit 200. The user can only drive the battery 310 to power the atomization unit 200 when applying force to the button 700. When no force is applied to the button 700, the battery 310 cannot power the atomization unit 200 and start the atomization unit 200, so that the user can use the above-mentioned paste atomization device 10 to control more accurately when inhaling than using the airflow sensor, and reduce the occurrence of dry burning caused by false triggering. Furthermore, because there is no need to set an airflow sensor, the structure of the atomization unit 200 is simple, and there is no need to set an auxiliary airway connected to the airflow sensor and connected to the main airway 401, which also avoids the aerosol remaining in the auxiliary airway after atomization, so that the more expensive solid atomization medium can be fully atomized and inhaled, reducing unnecessary waste of atomization medium.

[0071] The paste atomizing device 10 of the above embodiment has the following operating steps:

[0072] In the first step, the button 700 is pressed once, and the driving circuit board 320 controls the preheating element 240 to preheat the heating pot 220 for at least 5 seconds, so that the solid atomizing medium in the heating pot 220 melts to form a fluid atomizing medium and penetrates into the atomizing core 230 .

[0073] In the second step, the user continues to press the button 700 and inhales from the air outlet 101; the driving circuit board 320 controls the atomizer core 230 to work, and when the atomizer core 230 works, the molten atomizing medium flowing into the inside is further heated to produce aerosol for the user to inhale.

[0074] In the third step, the user releases the button 700 and stops inhaling, completing one inhalation action, and the atomizing core 230 also stops working, and the paste atomizing device 10 enters a standby state. When the user needs to inhale again, the second and third steps can be repeated.

[0075] Finally, it should be noted that the various technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
