[0036] An embodiment of the present application provides an electronic atomization device, wherein the electronic atomization device 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.

[0037] The following uses an electronic cigarette used to heat solid tobacco paste to generate aerosol as an example of an electronic atomization device to illustrate the structure of the electronic atomization device in this application. This embodiment is only used as an example and does not limit the technical scope of this application. It can be understood that in other embodiments, the electronic atomization device of this application is not limited to the above-mentioned electronic atomization device for heating solid tobacco paste, but can also be other electronic atomization devices for heating solid atomization media to generate aerosols, which is not limited here.

[0038] See Figures 1 to Figure 5 , FIG. 1 and FIG. 2 show the appearance of an electronic atomization device 10 in one embodiment of the present application, Figure 3 FIG. 1 shows an exploded schematic diagram of the electronic atomization device 10 in this embodiment. Figure 4 and Figure 5 The schematic diagram of the internal structure of the electronic atomization device 10 in this embodiment is shown. The electronic atomization device 10 provided in one embodiment of the present application includes a suction device 100 and an atomization unit 200. The suction device 100 includes a shell 110 and a power supply assembly 120 arranged in the shell 110. The shell 110 has a accommodating cavity 113, and the shell 110 is provided with a mounting groove 114. The mounting groove 114 is isolated from the accommodating cavity 113, and the groove wall of the mounting groove 114 is provided with an air hole 112 connected to the air outlet 111. The atomization unit 200 is detachably fixed and inserted in the mounting groove 114. The atomization unit 200 is also provided with an air inlet 201 and an air vent 202 that are connected to each other. The air inlet 201, the air vent 202, and the air vent 112 are connected to the air outlet 111 in sequence. The power supply component 120 is used to supply power to the atomization unit 200. When the power supply component 120 supplies power to the atomization unit 200, the atomization unit 200 can heat the atomization medium contained in the atomization unit 200 to generate aerosol and then discharge it through the vent hole 202, the air hole 112 and the air outlet hole 111 in sequence.

[0039] Specifically, Figure 4 and Figure 5 As shown, the power supply assembly 120 includes a battery 121 and a circuit board 122. The battery 121 is disposed on one side of the circuit board 122 and is electrically connected to the circuit board 122. The circuit board 122 is sleeved and clamped on the outer wall of the mounting groove 114 to be fixed in the accommodating cavity 113 of the housing 110. The circuit board 122 is provided with at least two electrodes 1221, as shown in FIG. Figure 6 As shown, the atomization unit 200 has at least two electrode contacts 206 correspondingly, and each electrode 1221 is electrically connected to a corresponding electrode contact 206. In this embodiment, there are three electrodes 1221 and three electrode contacts 206 respectively, and each electrode 1221 abuts against a corresponding electrode contact 206, thereby achieving electrical connection between the power supply component 120 and the atomization unit 200.

[0040] It should be noted that among all the electrodes 1221, one electrode 1221 is a positive electrode, another electrode 1221 is a negative electrode, and the remaining electrodes 1221 can be used for information reading, writing, collection, and interaction between the atomization unit 200 and the power supply component 120. For example, in this embodiment, there are three electrodes 1221. Except for the two electrodes 1221 used as the positive electrode and the negative electrode, the remaining electrode 1221 can be used to read the information in the chip, circuit or sampling resistor in the atomization unit 200, so that the suction device 100 can match different heating modes according to different atomization units 200 control.

[0041] It is also understandable that the suction device 100 may not be provided with the power supply component 120, and the atomization unit 200 may be powered by an external power supply, which is not limited here.

[0042] Please continue reading Figure 4 and Figure 5 In one embodiment, an airway tube 130 is provided in the housing 110 , and a main airway 131 runs through opposite ends of the airway tube 130 . More specifically, the top of the shell 110 is provided with a suction nozzle 115, and the air outlet hole 111 runs through the opposite ends of the suction nozzle 115. A first sealing member 140 made of silicone is provided at a position near the suction nozzle 115 in the accommodating chamber 113, and a second sealing member 150 made of silicone is also provided in the accommodating chamber 113. The first sealing member 140 and the second sealing member 150 are arranged relatively spaced apart, and the suction nozzle 115 is inserted into one side of the first sealing member 140, one end of the airway tube 130 is inserted into the side of the first sealing member 140 facing away from the suction nozzle 115, and the other end of the airway tube 130 is inserted into the second sealing member 150. The first sealing member 140 is used to prevent the condensate generated by the aerosol from flowing back into the shell 110 from the suction nozzle 115 and causing a short circuit in the power supply component 120, and the second sealing member 150 is used to prevent the condensate in the airway tube 130 from flowing back into the atomization unit 200.

[0043] In this way, by detachably inserting the atomizing unit 200 into the mounting groove 114, one end of the airway tube 130 is connected to the air outlet 111, and the other end is directly connected to the mounting groove 114 through the air hole 112, so that there are no other components in the airway tube 130. Compared with the structure in which the atomizing core 230 in the existing electronic atomizing device 10 is usually required to be arranged in the airway tube 130, this structure makes it easier for users to clean the condensed substances or other impurities remaining in the main airway 131. The user only needs to use the matching straight brush, insert it into the main airway 131 from the air outlet 111 at the suction nozzle 115, and it can directly penetrate the entire main airway 131, and clean all the impurities in the airway from the air hole 112, without any residual impurities, and the cleaning effect is very good. At the same time, there is no need to disassemble individual parts for cleaning, and the cleaning operation is very convenient.

[0044] For the specific structure of the atomization unit 200, see Figure 4 and Figure 6 The atomization unit 200 includes a main body 210, a heating pot 220 and an atomization core 230. The atomization chamber 203 is opened in the main body 210. The heating pot 220 is coaxially arranged in the atomization chamber 203 and coaxially arranged with the mounting groove 114. The heating pot 220 is a hollow cylindrical metal structure, which includes a first pot body 221 and a second pot body 222 which 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, and a first cavity 221a is opened in the first pot body 221, and a second cavity 222a connected to the first cavity 221a is opened in the second pot body 222. The first cavity 221a is provided with an atomization core 230 electrically connected to the electrode contact 206, and the second pot body 222 is used to accommodate the atomization medium. When the atomizer core 230 is powered on to generate heat, the solid atomization medium (eg, 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 aerosol.

[0045] 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 also provided with a preheating member 240 electrically connected to the electrode contact 206, 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.

[0046] Please continue reading Figure 4 and Figure 6 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 mounting groove 114. 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, and the air inlet 201 is opened on the box body 211. The box body 211 is made of hard plastic, which is used to protect the parts in the atomizing unit 200. The sealing ring 212 is made of silicone material, which 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 131 from flowing back into the atomizing chamber 203.

[0047] 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 114 .

[0048] In other embodiments, the air inlet 201 may also be provided on the side of the box body 211, and when the atomizing unit 200 is located in the mounting groove 114, the air inlet 201 faces the side wall of the mounting groove 114. At this time, the external air may flow to the air inlet 201 through the gap between the atomizing unit 200 and the mounting groove 114, and then flow through the inside of the atomizing unit 200. Of course, another through hole may also be provided at the position of the side wall of the mounting groove 114 corresponding to the air inlet 201, so as to allow the external air to enter the atomizing chamber 203.

[0049] The connection structure between the box body 211 and the sealing ring 212 may be as follows: Figure 6 As 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 suction device 100 is performed by the second sealing member 150. In this embodiment, the air hole 112 is opened on the second sealing member 150 and passes through the opposite sides of the second sealing member 150. The second sealing member 150 forms a part of the groove wall of the mounting groove 114. The end of the vent pipe 400 away from the suction nozzle 115 is inserted into the air hole 112 opened by the second sealing member 150. When the atomizer unit 200 is inserted into the mounting groove 114, one side of the second sealing member 150 abuts against the box body 211 of the atomizer unit 200, and the air hole 202 is opened on the box body 211, so that the air hole 112 and the air hole 202 are connected to each other.

[0050] However, it is worth noting that even after the atomization unit 200 and the suction device 100 are sealed by the second sealing member 150, a connection gap may still exist, causing the aerosol generated by the heating and atomization of the atomization unit 200 to overflow from the above-mentioned connection gap when passing through the connection between the atomization unit 200 and the suction device 100, thereby affecting the user's suction taste.

[0051] In order to solve this problem and make the electronic atomization device 10 of the present application have better connectivity and air tightness, a sealing structure is also provided between the atomization unit 200 and the housing 110 of the suction device 100. Specifically, the sealing structure is provided between the air hole 112 and the vent hole 202, and is used to seal the connection gap between the groove wall of the installation groove 114 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 112, thereby affecting the user's suction taste.

[0052] In one embodiment, the sealing structure is disposed on the suction device 100, and the sealing structure protrudes from the groove wall of the mounting groove 114 toward the inside of the mounting groove 114 and out of the side wall of the mounting groove 114. More specifically, as Figure 6As shown, the second sealing member 150 is slightly protruded from the side wall of the mounting groove 114 toward the mounting groove 114 ( Figure 6 The sealing structure is the portion of the second sealing member 150 that slightly protrudes from the side wall of the mounting groove 114, so that when the atomization unit 200 is inserted into the mounting groove 114, the protruding sealing structure can make the second sealing member 150 more tightly abut against the box body 211 of the atomization unit 200, thereby improving the sealing performance.

[0053] However, in the structure of the existing electronic atomization device 10, the sealing silicone is usually arranged inside the shell 110, and since the atomization unit 200 is a detachable consumable, when the electronic 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 installation groove 114, causing the outer surface of the atomization unit 200 to often rub against the sealing silicone. After a long time, the sealing silicone will cause the sealing performance to deteriorate due to wear. If the sealing silicone needs to be replaced, the shell 110 needs to be disassembled, so it will be more troublesome to replace the sealing silicone.

[0054] Therefore, based on the above reasons, the inventor of the present application has thought of providing a sealing structure on the atomization unit 200 to seal the atomization unit 200 and the suction device 100, so that when the atomization unit 200 is replaced, the sealing ring 212 can be replaced together, thereby eliminating the need to additionally replace the seal provided in the shell 110, thereby reducing unnecessary trouble and facilitating user operation.

[0055] Specifically, Figure 7 and Figure 8 As shown, the box body 211 is provided with an air inlet 201 and an air vent 202 that are interconnected, a through hole 212a is provided on the sealing ring 212, and the box body 211 has a slot 2114 that is connected to the air hole 112. At least a portion of the sealing ring 212, that is, at least the portion with the through hole 212a, is embedded in the slot 2114, so that the through hole 212a is located between the air hole 202 and the air hole 112, and is connected to the air hole 202 and the air hole 112, so that the portion of the sealing ring 212 embedded in the slot 2114 forms a sealing structure. More specifically, as Fig. 9As shown, the top wall of the box body 211 is provided with a through groove 2113 which passes through the top wall of the box body 211, and the box body 211 also has an inserting portion 2111, the vent hole 202 passes through the opposite sides of the inserting portion 2111 and is spaced apart from the through groove 2113, the inserting portion 2111 and the groove wall of the mounting groove 114 jointly form the above-mentioned slot 2114, when the portion of the sealing ring 212 provided with the through hole 212a is embedded in the slot 2114, the portion of the sealing ring 212 provided with the through hole 212a is exposed from the box body 211, thereby being able to play a sealing role.

[0056] Furthermore, combined with Figures 7 to 10 As shown, a sealing ring 213 surrounding the through hole 212a 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 114 (i.e., abuts against the part of the groove wall of the housing 110 forming the mounting groove 114), and the sealing ring 213 and the part of the sealing ring 212 embedded in the slot 2114 together form the above-mentioned sealing structure arranged between the atomizing unit 200 and the suction device 100. In this way, the sealing structure is arranged on the atomizing unit 200, which not only enables the atomizing unit 200 to form a better seal with the groove wall of the mounting groove 114, but also, even if the sealing ring 212 or the sealing ring 213 is worn and the sealing performance is reduced because the atomizing unit 200 often needs to be plugged in and out of the mounting groove 114, the sealing ring 212 can be replaced by the way when the atomizing unit 200 is replaced, so that the second sealing member 150 does not need to be replaced additionally, which is convenient for the user's operation.

[0057] 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. When the sealing ring 213 is detachably connected to the sealing ring 212, only the sealing ring 213 can be replaced when wear occurs.

[0058] 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 150 when the sealing performance between the atomization unit 200 and the housing 110 decreases.

[0059] Furthermore, in order to insert the atomizing unit 200 into the mounting groove 114 to a suitable depth, it is avoided that the atomizing unit 200 is inserted too shallowly or too deeply, which may cause the air hole 112 and the air vent 202 to be misaligned, or cause the electrode 1221 to be unable to contact the electrode contact 206. Figure 6As shown, 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 110. The step 2115 is used to limit the atomization unit 200 so that the atomization unit 200 can be inserted to a depth that allows the air hole 112 to be centered with the air vent 202 and the electrode 1221 to be in full contact with the electrode contact 206.

[0060] In addition, in order to facilitate the placement of the atomized value into the atomization unit 200, as Figure 4 , Figure 6 and Figure 7 As shown, one end of the atomization unit 200 also has an opening 207, and the opening 207 faces the second cavity 222a of the heating pot 220. The atomized 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 electronic atomization device 10 needs to load the atomized medium into the heating pot 220 before leaving the factory, it only needs to open the oil tank cover 250, load the solid atomized medium into the accommodating cavity 113 of the heating pot 220 through the above-mentioned opening 207, and then close the oil tank cover 250.

[0061] In a preferred embodiment, see Figure 3 , the mounting groove 114 runs through the opposite sides of the housing 110. In terms of the connection between the atomizer unit 200 and the housing 110, the atomizer unit 200 can be detachably fixed and inserted in the mounting groove 114 by means of magnetic attraction, or can be detachably fixed and inserted in the mounting groove 114 by means of a buckle 204 connection. Specifically, with regard to the connection structure of the buckle 204 connection, one of the outer wall of the atomizer unit 200 and the groove wall of the mounting groove 114 is provided with a buckle 204, and the other is provided with a slot 116 corresponding to the buckle 204, and the buckle 204 is snapped into the slot 116, so that the atomizer unit 200 can be fixedly inserted in the mounting groove 114. Compared with the magnetic 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 installation groove 114 due to insufficient magnetism. At the same time, it can avoid the problems of increased cost and increased device volume caused by setting up a magnetic attraction structure, so it has better technical effects.

[0062] 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 it is convenient for the user to use it, 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, because the installation groove 114 runs through the opposite sides of the shell 110, 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 114, and the atomizing unit 200 can be easily removed from the shell 110, which is convenient for the user's operation and greatly improves the user's experience.

[0063] Furthermore, in order to prevent the user from inserting the atomizer unit 200 into the mounting groove 114 in the reverse direction, that is, to ensure that the atomizer unit 200 can only be inserted into the mounting groove 114 at one of the two ends of the mounting groove 114 along its own axial direction, the two ends of the mounting groove 114 along 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 114 from the mounting end, thereby preventing the atomizer unit from being inserted in the reverse direction.

[0064] 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 114; the inner circumferential surface of the mounting groove 114 may also be provided as a structure extending obliquely along the axial direction of the mounting groove 114, 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.

[0065] Furthermore, in order to prevent the atomization unit 200 from rotating and thus being misaligned when inserted into the mounting groove 114, the outer circumferential surface of the atomization unit 200 includes a first plane 205, and the first plane 205 is formed by a side surface of the sealing ring 212, and the electrode contact 206 and the through hole 212a are both arranged on the first plane 205; correspondingly, the groove wall of the mounting groove 114 includes a second plane 114a that is in contact with the first plane 205, and the air hole 112 is opened on the second plane 114a, and the groove wall contour of the mounting groove 114 matches the outer circumferential surface contour of the part of the atomization unit 200 inserted in the mounting groove 114. In the embodiment shown in the figure, the outer peripheral surface of the part of the atomization unit 200 inserted into the mounting groove 114 has a plane, namely the first plane 205, and the rest are arc surfaces. Correspondingly, the groove wall of the mounting groove 114 also has a plane, namely the second plane 114a, and the rest are also arc surfaces. When the atomization unit 200 is inserted into the mounting groove 114, there is only one installation direction in its own circumferential direction, thereby avoiding the atomization unit 200 from rotating and causing dislocation when inserted into the mounting groove 114.

[0066] Of course, it is understandable that the groove wall profile of the mounting groove 114 and the outer peripheral surface profile of the part of the atomization unit 200 inserted in the mounting groove 114 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 114.

[0067] In a more preferred embodiment, if Figure 3 As shown, the central axis of the heating pot 220 is perpendicular to the central axis of the airway tube 130 (i.e., the central axis of the mounting groove 114 is perpendicular to the central axis of the main airway 131). In this way, when the electronic atomization device 10 is held by the user for horizontal inhalation (i.e., when the opening 207 of the atomization unit 200 is facing upward), the solid atomization medium is converted into a molten state that can flow under the preheating effect of the preheating member 240. 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 a vertical direction, and the outflow path of the aerosol is in a 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 131. Moreover, through the above arrangement, the space inside the shell 110 can be fully utilized in the flow direction of the atomized medium to arrange the power supply component 120, so that the internal structure of the electronic atomization device 10 is more compact, thereby achieving the purpose of making the appearance of the electronic atomization device 10 smaller and flatter.

[0068] In addition, in order to enable the user to conveniently control the working state of the electronic atomization device 10, that is, to conveniently control the electronic 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 electronic atomization device 10 is not working, referring to Figure 2, the shell 110 is also provided with a button 160 on the side of the opening 207 facing away from the atomization unit 200 for the user to switch between the above-mentioned working states. The button 160 can move relative to the shell 110 under the action of external force, so that the button 160 can be connected to the circuit board 122, thereby driving the circuit board 122 in turn to respectively control the opening and closing of the preheating component 240 and the opening and closing of the atomization core 230.

[0069] In this way, by arranging the opening 207 of the atomization unit 200 relative to the button 160, the electronic 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 110 with his hand, press the button 160 with his thumb, or toggle the button 160 to easily control the electronic atomization device 10 to be in a heating state, a preheating state or a standby state. Compared with the button 160 being arranged on the same side as the opening 207 of the atomization unit 200 or being arranged 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 160 to control the electronic 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 121 to power the atomization unit 200 when applying force to the button 160. When no force is applied to the button 160, the battery 121 cannot power the atomization unit 200 and start the atomization unit 200, so that the user can use the above-mentioned electronic 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 131, 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.

[0070] The electronic atomization device 10 of the above embodiment has the following operating steps:

[0071] In the first step, the button 160 is pressed once, and the driving circuit board 122 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 .

[0072] In the second step, the user continues to press the button 160 and inhales from the air outlet 111; the driving circuit board 122 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.

[0073] In the third step, the user releases the button 160 and stops inhaling, completing one inhalation action, and the atomizer core 230 also stops working, and the electronic atomizer device 10 enters a standby state. When the user needs to inhale again, the second and third steps can be repeated.

[0074] 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.

[0075] 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.
