Description

Technical Field

[0001] The present application relates to the field of electronic atomization technology, and in particular to an electronic atomization device. Background Art

[0002] Electronic atomizers, also known as e-cigarettes, heat and vaporize an atomizing medium to create an aerosol for the user to inhale, simulating the sensation of smoking. As a popular alternative to cigarettes, they are a popular choice among smokers. Traditional electronic atomizers consist of an atomizer unit and a power supply unit. The atomizer unit contains an oil reservoir, which stores the atomizing medium. The power supply unit supplies power to the atomizer unit, heating and vaporizing the atomizing medium in the reservoir to create an aerosol for the user to inhale.

[0003] However, as existing electronic atomizer devices become increasingly powerful, the battery consumption of these devices increases significantly. This is especially true for users who prefer high-power, high-volume vapor production. This can lead to the device displaying low battery after a short puff. While most electronic atomizer devices have a charging port that allows them to be connected to an external power source, this can still be inconvenient for users in situations where no external power source is available. Therefore, effectively extending battery life is crucial. Utility Model Content

[0004] Based on this, the purpose of this application is to provide an electronic atomization device to solve the technical problem that the battery power in the existing electronic atomization device is consumed quickly, resulting in the inability to extend the battery life when the electronic atomization device is used in situations without an external power supply.

[0005] According to one aspect of the present application, an electronic atomization device is provided, comprising:

[0006] Support unit;

[0007] The atomization unit and the power supply unit are both disposed within the support unit. The power supply unit includes a battery, a circuit board, and a power generation element. The battery is electrically connected to the circuit board, and the circuit board is electrically connected to the power generation element and the atomization unit, respectively. The power generation element is provided with a drive wheel that can rotate around its central axis.

[0008] The handle is movably connected to the support unit and is transmission-connected to the drive wheel via a transmission assembly connected to the support unit. The transmission assembly has at least three transmission ratios between the handle and the drive wheel. The handle can move relative to the support unit under the action of an external force. In response to the movement of the handle, the transmission assembly can drive the drive wheel to rotate, so that the generating element can convert mechanical energy into electrical energy.

[0009] In one embodiment, the transmission assembly includes a rack, a first transmission wheel set, and a second transmission wheel set. The rack is mounted on the handle and meshes with the first transmission wheel set to form a first-stage transmission ratio; the first transmission wheel set meshes with the second transmission wheel set to form a second-stage transmission ratio; the second transmission wheel set meshes with the drive wheel to form a third-stage transmission ratio.

[0010] The first-stage transmission ratio, the second-stage transmission ratio, and the third-stage transmission ratio are configured to gradually increase the rotational speeds of the first transmission wheel set, the second transmission wheel set, and the drive wheel around their respective central axes.

[0011] In one embodiment, the first transmission wheel group includes a first transmission wheel and a second transmission wheel arranged coaxially, the second transmission wheel group includes a third transmission wheel and a fourth transmission wheel arranged coaxially, the first transmission wheel is engaged with the rack, the second transmission wheel is engaged with the third transmission wheel, and the fourth transmission wheel is engaged with the drive wheel; the diameter of the second transmission wheel is larger than the diameters of the third transmission wheel and the fourth transmission wheel, and the diameter of the fourth transmission wheel is larger than the diameter of the drive wheel.

[0012] In one embodiment, the driving wheel is located between the first transmission wheel and the fourth transmission wheel in its radial direction.

[0013] In one embodiment, one of the third transmission wheel and the fourth transmission wheel is provided with a slot, and the other is provided with a clamping portion that is clamped to the slot, wherein the slot wall includes a first slot wall and a second slot wall, the second slot wall is arranged obliquely relative to the first slot wall, and the clamping portion has a first side wall parallel to the first slot wall and a second side wall parallel to the second slot wall;

[0014] When the third transmission wheel and the fourth transmission wheel tend to rotate in the same direction, the first groove wall is in contact with the first side wall; when the third transmission wheel and the fourth transmission wheel tend to rotate in opposite directions, the second groove wall and the second side wall slide relative to each other, so that the fourth transmission wheel can move away from the third transmission wheel along its own axial direction.

[0015] In one embodiment, a second elastic element is provided on the fourth transmission wheel, and the second elastic element is configured to provide an elastic force to make the fourth transmission wheel approach the third transmission wheel and reset when the fourth transmission wheel moves away from the third transmission wheel.

[0016] In one embodiment, the handle is rotatably connected to the support unit via a rotating shaft, and the handle can rotate relative to the support unit around the central axis of the rotating shaft.

[0017] In one embodiment, the handle is further connected to the support unit via a first elastic element, and the first elastic element is configured to provide an elastic force for resetting the handle when the handle moves relative to the support unit.

[0018] In one embodiment, a charging port is provided on the circuit board, and the charging port is used for plugging an external power cord to charge the battery.

[0019] In one embodiment, the handle is provided with a receiving cavity, and the battery is disposed in the receiving cavity.

[0020] The above-mentioned electronic atomization device, on the one hand, has a power generation element electrically connected to the battery set in the support unit, and a handle movably connected to the support unit, and the handle is connected to the drive wheel of the power generation element through a transmission assembly connected to the support unit, so that the user can convert mechanical energy into electrical energy and store it by repeatedly applying external force to the handle, and then charge the battery or directly provide electrical energy to the atomization unit. Therefore, when the user uses the electronic atomization device in an environment without an external power supply, the above-mentioned setting can effectively extend the use time of the electronic atomization device; on the other hand, by constructing the transmission assembly with at least three levels of transmission ratio, the transmission assembly can convert the speed of the handle relative to the support unit into a faster rotation speed at which the drive wheel of the power generation element can generate electricity. In this way, when the user moves the handle relative to the support unit with a smaller external force, the power generation element can generate electrical energy, which can save more effort when manually generating electricity. The above greatly improves the user experience when using the electronic atomization device. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] An embodiment of the present application provides an electronic atomization device, which is used to heat an atomization medium stored inside the device to form an aerosol for inhalation by a user.

[0040] The following describes the structure of the electronic atomization device in this application, taking an electronic cigarette as an example. This embodiment is merely an example and does not limit the technical scope of this application. It is understood that in other embodiments, the electronic atomization device of this application is not limited to an electronic cigarette, but can also be any other electronic atomization device that can atomize an atomizing medium into an aerosol, without limitation here.

[0041] See Figure 1 and Figure 2 , Figure 1 FIG. 1 shows a schematic diagram of the appearance of an electronic atomization device 10 in one embodiment of the present application. Figure 2 The figure shows a cross-sectional view of the internal structure of the electronic atomization device 10 in this embodiment. The electronic atomization device 10 provided in one embodiment of the present application includes a support unit 100, an atomization unit 200, a power supply unit 300 and a handle 400, wherein the support unit 100 is used to accommodate the internal components of the electronic atomization device 10 and provide support for the internal components of the electronic atomization device 10; the atomization unit 200 and the power supply unit 300 are both arranged in the shell 110, and the atomization unit 200 is used to heat the atomization medium contained in itself to The atomizing medium is heated and atomized to generate an aerosol for the user to inhale; the power supply unit 300 is electrically connected to the atomizing unit 200, and is used to provide electrical energy to the atomizing unit 200 so that the atomizing unit 200 can heat the atomizing medium; the handle 400 is movably connected to the support unit 100 and is transmission-connected to the power supply unit 300. Under the action of an external force, the handle 400 can move relative to the support unit 100, thereby enabling the power supply unit 300 to convert mechanical energy into electrical energy, so as to be able to directly power the atomizing unit 200 or store the electrical energy. In this way, the electronic atomizing device 10 has the function of manual power generation. When the user uses the electronic atomizing device 10 in an environment without an external power supply, the electronic atomizing device 10 can also be charged when the battery 310 of the atomizing unit 200 is exhausted, thereby effectively extending the use time of the electronic atomizing device 10.

[0042] Specifically, in one embodiment, Figure 2 As shown, the support unit 100 includes a housing 110 and a bracket 120. The housing 110 forms a sealed cavity. The bracket 120 is disposed within the cavity formed by the housing 110 and divides the cavity formed by the housing 110 into a first cavity and a second cavity. The atomization unit 200 is disposed within the first cavity, and the power supply unit 300 is disposed within the second cavity. The housing 110 is provided with an air inlet hole for allowing outside air to enter the housing 110. When a user uses the electronic atomization device 10 for inhalation, outside air can enter the housing 110 and then enter the atomization unit 200, and be inhaled by the user together with the smoke generated after the atomization medium is heated and atomized.

[0043] like Figure 3 and Figure 4 As shown, in the embodiment shown in the figure, an opening 111 communicating with the interior of the shell 110 is provided on one side surface of the shell 110, and the handle 400 is movably connected to the bracket 120, so that it can move relative to the support unit 100 to open or close the opening 111. In a natural state, the handle 400 is in a state of opening the opening 111. When the user presses the handle 400, so that the handle 400 moves relative to the support unit 100 and closes the above-mentioned opening 111, the handle 400 can drive the power supply unit 300 to generate electrical energy. Optionally, in this embodiment, the handle 400 is rotatably connected to the bracket 120 via a rotating shaft, so that the handle 400 can rotate relative to the bracket 120 around the central axis of the rotating shaft.

[0044] Of course, it is understandable that the handle 400 may also be movably connected to the housing 110. For example, the handle 400 may be a knob rotatably connected to the housing 110, and the user can turn the knob to enable the power supply unit 300 to generate electricity. Alternatively, in other embodiments, the manner in which the handle 400 is movably connected to the support unit 100 is not limited to being rotatably connected, but may also be slidably connected to the support unit 100, thereby being able to translate relative to the support unit 100 to drive the power supply unit 300 to generate electricity. This is not limited herein.

[0045] Preferably, if Figure 2 and Figure 4As shown, the handle 400 is further connected to the support unit 100 via a first elastic element 500. The first elastic element 500 is configured to provide an elastic force to return the handle 400 to its original position when the handle 400 moves relative to the support unit 100. For example, in the embodiment shown in the figure, the first elastic element 500 is a torsion spring that is connected to both the bracket 120 and the handle 400. The torsion spring is sleeved on the rotating shaft. When a user presses the handle 400 to rotate the handle 400 relative to the support unit 100 about the central axis of the rotating shaft, the torsion spring can provide an elastic force that can cause the handle 400 to rotate in the opposite direction about the central axis of the rotating shaft back to its original position (i.e., the position where the handle 400 opens the opening 111 of the housing 110), making it convenient for the user to press the handle repeatedly.

[0046] Better yet, see Figure 1 A locking switch 600 is movably provided on the shell 110. When the user does not need to generate electricity manually, the locking switch 600 can lock the handle 400 in the position of closing the opening 111 of the shell 110. At this time, the handle 400 cannot move relative to the support unit 100; when manual power generation is required, the locking switch 600 is turned on, and the handle 400 bounces open under the elastic force provided by the first elastic element 500 and is located at the position of opening the opening 111 of the shell 110. The handle 400 can move relative to the support unit 100 to enable manual power generation.

[0047] Regarding the structure of the atomization unit 200 , the atomization unit 200 includes an oil storage cup, a vent pipe, an atomization core, etc. The structure thereof can refer to the prior art and will not be described in detail here.

[0048] Regarding the structure of the power supply unit 300, see Figure 2 、 Figure 5 and Figure 6 In the embodiment shown in the figure, the power supply unit 300 includes a battery 310, a circuit board 320, and a power generation element 330. The battery 310 is electrically connected to the circuit board 320, which is in turn electrically connected to the power generation element 330 and the atomization unit 200. The battery 310 is used to store electrical energy, the power generation element 330 is used to convert the mechanical energy generated by the movement of the handle 400 relative to the support unit 100 into electrical energy, and the circuit board 320 is used to control the logic on and off of the circuit to allow electrical energy to be charged into the battery 310, and is used to control the battery 310 to power the atomization unit 200.

[0049] To conserve internal space within the electronic atomizer device 10, in a preferred embodiment, the handle 400 defines a housing cavity within which the battery 310 is disposed. This allows the battery 310 to be housed within the support unit 100 together with the handle 400 when not in use. When manual power generation is required, the battery 310 can move relative to the support unit 100 along with the handle 400. This eliminates the need for a separate cavity within the bracket 120 for accommodating the battery 310, thereby conserving internal space within the electronic atomizer device 10 and making the electronic atomizer device 10 more portable and compact.

[0050] Since the space in the housing 110 is limited, in order to facilitate the arrangement of the circuit board 320 and save space, Figure 5 and Figure 6 In the embodiment shown in , the circuit board 320 includes a first plate 321 and a second plate 322 electrically connected to each other. The first plate 321 and the second plate 322 are respectively arranged on opposite sides of the bracket 120 along its own thickness direction. The power generation element 330 is arranged in the bracket 120 and is located between the first plate 321 and the second plate 322. At the same time, the power generation element 330 is also electrically connected to the first plate 321, and the atomization unit 200 and the battery 310 are electrically connected to the second plate 322. In this way, when the power generation element 330 converts mechanical energy into electrical energy, the power generation element 330 can transfer the electrical energy to the second plate 322 under the control of the first plate 321. The second plate 322 can control the electrical energy to be stored in the battery 310 or directly power the atomization unit 200. Of course, in other embodiments, the circuit board 320 can also be a single plate structure, which can be freely arranged as needed and is not limited here.

[0051] As an improvement to the above embodiment, the circuit board 320 is further provided with a charging port 323 for plugging in an external power cord to charge the battery 310. This allows the electronic atomization device 10 to not only have the function of manually generating electricity, but also, like conventional electronic atomization devices 10, be charged using an external power source, thus further diversifying the charging methods of the electronic atomization device 10. For example, the charging port 323 can be a USB port or a TPYE-C port, etc., and there is no particular limitation.

[0052] Further, in the connection structure of the handle 400 and the power supply unit 300 for transmission connection, refer to Figure 7 and Figure 8The power supply unit 300 has a driving wheel 331 that can rotate around its own central axis. The handle 400 is connected to the driving wheel 331 through a transmission assembly 340. When the handle 400 moves relative to the support unit 100, the transmission assembly 340 can drive the driving wheel 331 to rotate around its own central axis, so that the power generation element 330 can convert mechanical energy into electrical energy for operating the atomization unit 200.

[0053] Preferably, the transmission assembly 340 has a three-level transmission ratio. The purpose of this arrangement is to convert the speed at which the handle 400 moves relative to the support unit 100 into a faster rotation speed at which the driving wheel 331 of the generating element 330 can enable the generating element 330 to generate electricity. In this way, when the user moves the handle 400 relative to the support unit 100 with a smaller external force, the generating element 330 can generate electricity, thereby saving more effort when manually generating electricity.

[0054] Of course, the transmission ratio of the transmission assembly 340 can also be more than three levels, and can be set according to the different power generation powers of different models of power generation elements 330.

[0055] In some embodiments, the transmission assembly 340 can be a gear meshing structure, or a rack 341 and a gear meshing structure, or a chain drive or belt drive. Figure 7 and Figure 8 In the embodiment shown in the figure, the transmission assembly 340 is a structure in which a rack 341 is engaged with gears and multiple gears are engaged. Specifically, the transmission assembly 340 includes a rack 341, a first transmission wheel group 342 and a second transmission wheel group 343. The central axes of the first transmission wheel group 342 and the second transmission wheel group 343 are parallel to each other. The rack 341 is mounted on the handle 400 and is engaged with the first transmission wheel group 342 to form a first-stage transmission ratio; the first transmission wheel group 342 is engaged with the second transmission wheel group 343 to form a second-stage transmission ratio; the second transmission wheel group 343 is engaged with the driving wheel 331 to form a third-stage transmission ratio; the first-stage transmission ratio, the second-stage transmission ratio and the third-stage transmission ratio are all less than 1, and the first-stage transmission ratio, the second-stage transmission ratio and the third-stage transmission ratio gradually decrease, so that the speeds of the first transmission wheel group 342, the second transmission wheel group 343 and the driving wheel 331 rotating around their own central axes respectively increase step by step.

[0056] Alternatively, because the handle 400 rotates about the rotation axis relative to the support unit 100, the edge of the rack 341 provided with the meshing teeth is arcuate, so that when the handle 400 rotates about the center of the rotation axis, the rack 341 can always mesh with the first transmission wheel 3421, thereby preventing the rack 341 from disengaging from the first transmission wheel assembly 342. It is readily understood that when the handle 400 translates relative to the support unit 100, the edge of the rack 341 provided with the meshing teeth can be correspondingly designed to be linear.

[0057] More specifically, the first transmission wheel group 342 includes a first transmission wheel 3421 and a second transmission wheel 3422 arranged coaxially, and the second transmission wheel group 343 includes a third transmission wheel 3431 and a fourth transmission wheel 3432 arranged coaxially. The first transmission wheel 3421, the second transmission wheel 3422, the third transmission wheel 3431 and the fourth transmission wheel 3432 are all gears. The rack 341 is engaged with the first transmission wheel 3421, the second transmission wheel 3422 is engaged with the third transmission wheel 3431, and the fourth transmission wheel 3432 is engaged with the drive wheel 3431. wheel 331; the diameter of the second transmission wheel 3422 is larger than the diameters of the third transmission wheel 3431 and the fourth transmission wheel 3432, so that the rotational speed of the third transmission wheel 3431 and the fourth transmission wheel 3432 can be greater than the rotational speed of the second transmission wheel 3422, and the diameter of the fourth transmission wheel 3432 is larger than the diameter of the driving wheel 331, so that the rotational speed of the driving wheel 331 is greater than the rotational speed of the fourth transmission wheel 3432, thereby achieving the purpose of gradually increasing the rotational speeds of the first transmission wheel group 342, the second transmission wheel group 343 and the driving wheel 331.

[0058] Optionally, the driving wheel 331 is located between the first transmission wheel 3421 and the fourth transmission wheel 3432 in its radial direction, so that the space of the electronic atomization device 10 can be further saved, the volume of the electronic atomization device 10 can be reduced, and the structure is more compact.

[0059] So, Figure 7 and Figure 8 Observing from the X direction indicated by the middle arrow, when the user presses the handle 400, causing the rack 341 to drive the first transmission wheel 3421 to rotate counterclockwise around its own central axis, the second transmission wheel 3422 will also rotate counterclockwise around its own central axis, thereby driving the third transmission wheel 3431 and the fourth transmission wheel 3432 to rotate clockwise around their own central axes. The fourth transmission wheel 3432 in turn drives the driving wheel 331 to rotate counterclockwise around its own central axis, thereby enabling the generating element 330 to generate electrical energy.

[0060] In addition, it should be noted that in some cases, when some power generation elements 330 are generating electricity, the driving wheel 331 can only generate electricity when it rotates in one direction, and cannot generate electricity when it rotates in the opposite direction. For example, in the embodiment of the present application, Figure 7 and Figure 8When viewed in the X direction indicated by the middle arrow, the driving wheel 331 rotates counterclockwise to enable the driving element to generate electricity. The driving element cannot generate electricity when it rotates clockwise. When the elastic force generated by the first elastic element 500 drives the handle 400 to reset (i.e., when the handle 400 is driven to open the opening 111 of the housing 110), it drives the first transmission wheel 3421 and the second transmission wheel 3422 of the first transmission wheel assembly 342 to rotate in the opposite direction (i.e., rotate clockwise). Since the second transmission wheel 3422 is engaged with the third transmission wheel 3431, the third transmission wheel 3431 also rotates in the opposite direction.

[0061] At this time, in order to prevent the fourth transmission wheel 3432 from rotating in the reverse direction along with the third transmission wheel 3431, and thus prevent the fourth transmission wheel 3432 from driving the driving wheel 331 to rotate clockwise around its own central axis, the fourth transmission wheel 3432 can still drive the driving wheel 331 to rotate counterclockwise around its own central axis to continue generating electricity. Figure 9 and Figure 10 In a preferred embodiment, one of the third transmission wheel 3431 and the fourth transmission wheel 3432 is provided with a slot 3432a, and the other is provided with a clamping portion 3431a that is clamped in the slot 3432a. In the embodiment shown in the figure, the engaging slot 3432a is defined on a side of the fourth transmission wheel 3432 close to the third transmission wheel 3431, and the engaging portion 3431a is defined on a side of the third transmission wheel 3431 close to the fourth transmission wheel 3432. The slot walls of the engaging slot 3432a include a first slot wall 3432c and a second slot wall 3432d. The first slot wall 3432c is parallel to the central axis of the second transmission wheel assembly 343, that is, the first slot wall 3432c is perpendicular to the end face of the third transmission wheel 3431, and the second slot wall 3432d is inclined relative to the first slot wall 3432c. The engaging portion 3431a has a first side wall 3431b parallel to the first slot wall 3432c and a second side wall 3431c parallel to the second slot wall 3432d.

[0062] Thus, through the above arrangement, when the handle 400 is pressed to move toward the opening 111 of the closed shell 110, the third transmission wheel 3431 and the fourth transmission wheel 3432 have a tendency to rotate in the same direction. At this time, the first groove wall 3432c abuts and fits against the first side wall 3431b, and the third transmission wheel 3431 and the fourth transmission wheel 3432 can rotate in the same direction, and the fourth transmission wheel 3432 drives the driving wheel 331 to rotate counterclockwise (as viewed in the direction indicated by the X direction in the figure); and when the handle 400 is driven by the elastic force generated by the first elastic element 500 to move in the direction of opening the shell 110, since the second groove wall 3432d and the second side wall 3431c are respectively relative to the first groove wall 3432, c is inclinedly arranged with respect to the first side wall 3431b, so that the third transmission wheel 3431 tends to rotate in the opposite direction to the fourth transmission wheel 3432. At this time, the second side wall 3431c abuts against the second groove wall 3432d and slides relative to each other, causing the third transmission wheel 3431 to rotate in the opposite direction to the fourth transmission wheel 3432 and abut against the fourth transmission wheel 3432, so that the fourth transmission wheel 3432 moves away from the third transmission wheel 3431 along its own axis. As a result, the fourth transmission wheel 3432 can still drive the driving wheel 331 to rotate in the original rotation direction (counterclockwise when viewed in the direction indicated by the X direction in the figure) at a lower speed, thereby constantly rotating the driving wheel 331 in the same direction and keeping the generating element 330 generating electricity.

[0063] Furthermore, to ensure that the third transmission wheel 3431 and the fourth transmission wheel 3432 are securely connected when connected and have sufficient force to separate them when moving away from each other, preferably, there are multiple slots 3432a, and the multiple slots 3432a are evenly distributed around the central axis of the third transmission wheel 3431. There are also multiple engaging portions 3431a, and the multiple engaging portions 3431a are also evenly distributed around the central axis of the fourth transmission wheel 3432. Each engaging portion 3431a engages with a corresponding slot 3432a. It should be noted that there is no particular limitation on the number of slots 3432a and engaging portions 3431a.

[0064] Furthermore, to ensure that the fourth transmission wheel 3432 automatically returns to its original position and reapproaches the third transmission wheel 3431 after moving away from the third transmission wheel 3431, a second elastic element 344 is provided on the fourth transmission wheel 3432 and connected to the support unit 100 via the second elastic element 344. The second elastic element 344 is configured to provide an elastic force that causes the fourth transmission wheel 3432 to approach the third transmission wheel 3431 and return to its original position when the fourth transmission wheel 3432 moves away from the third transmission wheel 3431. Exemplarily, the second elastic element 344 is a spring coaxially connected to the fourth transmission wheel 3432, with one end of the second elastic element abutting the bracket 120 and the other end abutting the fourth transmission wheel 3432. When the fourth transmission wheel 3432 moves away from the third transmission wheel 3431, the second elastic element 344 is compressed and elastically deformed, thereby generating an elastic force that causes the fourth transmission wheel 3432 to return to its original position.

[0065] It can be seen that the electronic atomization device 10 provided in the present application not only has the function of manual power generation, but can also be charged by an external power supply, so that it can be applied to a variety of different environments. In an environment without an external power supply, the battery 310 can be charged or the atomization unit 200 can be powered anytime and anywhere, thereby extending the use time of the electronic atomization device 10; and by providing a transmission assembly 340 with a transmission ratio of three or more levels, when the user moves the handle 400 relative to the support unit 100 with a smaller external force, the power generation element 330 can generate electrical energy, so that manual power generation can be more labor-saving. All of the above greatly improves the user experience when using the electronic atomization device 10.

[0066] Finally, it should be noted that the various technical features of the above-described embodiments can be combined arbitrarily. In order 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.

[0067] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
