Description

Technical Field

[0001] This invention relates to the field of atomization technology, and in particular to an atomization component and atomization device. Background Technology

[0002] Aerosols are colloidal dispersion systems formed by small solid or liquid particles dispersed and suspended in a gaseous medium. Since aerosols can be absorbed by the human body through the respiratory system, atomizing devices that generate aerosols by heating aerosol matrices such as medical liquids can be used in various fields such as medicine to deliver inhalable aerosols to users.

[0003] In existing atomizing devices, the aerosol matrix is ​​usually stored in a liquid storage tank. During the operation of the atomizing device, the aerosol matrix is ​​absorbed and consumed by the matrix, and a negative pressure will gradually be generated in the liquid storage tank, which will affect the speed of liquid supply to the atomizing core and cause poor liquid flow. As a result, the atomizing core will dry-burn because the liquid consumption rate is greater than the supply rate.

[0004] To prevent the atomizer coil from burning out, a ventilation channel is usually formed by the pores of the atomizer coil substrate and the assembly gap of the atomizing device. When the liquid in the reservoir decreases, outside gas will enter the reservoir through the ventilation channel and fill the space freed up by the consumed liquid, thus preventing poor liquid flow and dry burning caused by negative pressure in the reservoir.

[0005] However, the study found that the size of the ventilation channel formed by the pores of the substrate and the assembly gap of the atomizing device is greatly affected by the dimensional tolerances of the parts, assembly tolerances, and the compression of the substrate. The dimensional stability of the cross-sectional area of ​​the ventilation channel is low, resulting in poor consistency of the ventilation pressure in the atomizing device. When the ventilation channel is too narrow, leading to excessive ventilation pressure, gas cannot enter the liquid storage chamber in time to balance the pressure, causing the atomizing device to dry-burn. Conversely, when the ventilation channel is too large, leading to insufficient ventilation pressure, the aerosol matrix in the liquid storage chamber is prone to leaking through the ventilation channel, especially during suction or negative pressure reliability testing, which exacerbates this phenomenon and causes leakage in the atomizing device, thus causing inconvenience in its use. Summary of the Invention

[0006] Therefore, it is necessary to provide an atomizing component and atomizing device to address the problem of poor air exchange pressure consistency in atomizing devices. This atomizing component and atomizing device can achieve the technical effect of improving the consistency of air exchange pressure.

[0007] According to one aspect of this application, an atomizing component is provided, comprising:

[0008] A liquid storage shell with a liquid storage compartment;

[0009] An inner liquid inlet pipe is housed within the liquid storage chamber. The inner liquid inlet pipe includes an air inlet channel, an atomizing core housing cavity, and an air outlet channel that are interconnected. The air inlet channel and the air outlet channel are respectively connected to the external air of the atomizing assembly.

[0010] An atomizing core is housed within an atomizing core housing cavity; the inner wall of the atomizing core forms an atomizing cavity, which is connected to the air inlet channel and the air outlet channel;

[0011] The inner wall of the inner liquid inlet pipe and the atomizing core define a first ventilation channel, which connects the air inlet channel and the liquid storage tank, and / or the first ventilation channel connects the air outlet channel and the liquid storage tank.

[0012] In one embodiment, the inner liquid inlet tube includes an inner liquid inlet tube top wall, an inner liquid inlet tube bottom wall, and an inner liquid inlet tube side wall connected to the inner liquid inlet tube top wall and the inner liquid inlet tube bottom wall. The air inlet channel is opened in the inner liquid inlet tube bottom wall, the air outlet channel is opened in the inner liquid inlet tube top wall, and the diameter of the air outlet channel or the air inlet channel is smaller than the diameter of the atomizing core receiving cavity.

[0013] The atomizing core is located between the top wall and the bottom wall of the inner liquid inlet tube, and the atomizing core is spaced apart from the top wall and / or the bottom wall of the inner liquid inlet tube to define and form the first ventilation channel.

[0014] In one embodiment, the atomizing core has an inwardly recessed groove on one side of the surface facing the top wall and / or the bottom wall of the inner liquid inlet tube, and the groove wall together with the top wall and / or the bottom wall of the inner liquid inlet tube defines the first ventilation channel.

[0015] In one embodiment, an air exchange groove is provided on the top wall and / or bottom wall of the inner liquid inlet tube facing the atomizing core receiving cavity.

[0016] In one embodiment, the inner liquid inlet pipe has an inner liquid inlet pipe vent, which connects the first venting channel and the liquid storage tank.

[0017] In one embodiment, one end of the vent hole of the inner liquid inlet pipe is connected to the first ventilation channel, and the other end of the vent hole of the inner liquid inlet pipe extends through to the outer surface of the inner liquid inlet pipe along the radial direction of the inner liquid inlet pipe.

[0018] In one embodiment, the vent of the inner liquid inlet tube includes a first venting section and a second venting section. The first venting section extends from the top wall or bottom wall of the inner liquid inlet tube toward the atomizing core receiving cavity to the side surface of the top wall or bottom wall of the inner liquid inlet tube away from the atomizing core receiving cavity. The second venting section is formed on the side surface of the top wall or bottom wall of the inner liquid inlet tube away from the atomizing core receiving cavity. One end of the second venting section is connected to the first venting section, and the other end of the second venting section is connected to the outer edge of the top wall or bottom wall of the inner liquid inlet tube.

[0019] In one embodiment, the atomizing component further includes an external liquid inlet pipe, which is housed within the liquid storage chamber and sleeved outside the internal liquid inlet pipe. The internal liquid inlet pipe and the external liquid inlet pipe define a second ventilation channel that connects the first ventilation channel and the liquid storage chamber.

[0020] In one embodiment, the outer liquid inlet pipe is provided with a limiting rib extending along the axial direction of the inner liquid inlet pipe and surrounding the outer side of the inner liquid inlet pipe, and the second ventilation channel is formed between the limiting rib and the outer circular surface of the side wall of the inner liquid inlet pipe.

[0021] In one embodiment, the atomizing core includes a heating element and a cylindrical base, the heating element being circumferentially disposed around the base;

[0022] The matrix has a porous structure.

[0023] In one embodiment, the substrate is porous ceramic or fiber cotton.

[0024] According to another aspect of this application, an atomizing device is provided, including the atomizing components described above.

[0025] The aforementioned atomizing component, on the one hand, addresses the issue that when the liquid in the storage tank decreases, causing a drop in air pressure within the atomizing chamber, gas from the outlet channel of the inner liquid inlet pipe enters the storage tank through the first ventilation channel and the ventilation hole of the inner liquid inlet pipe to fill the space freed up by the consumption of the aerosol matrix. This balances the air pressure between the storage tank and the outside atmosphere, resolving the problem of dry burning of the atomizing core caused by aerosol matrix supply compensation. On the other hand, compared to existing technologies that rely on the pores of the substrate itself and assembly gaps to form ventilation channels, the dimensions of the first ventilation channel and the ventilation hole of the inner liquid inlet pipe in this application are fixed, thereby creating a stable ventilation pressure and ensuring high consistency in the ventilation process of the atomizing device.

[0048] like Figure 1 and Figure 2 As shown, one embodiment of this application provides an atomizing device (not shown), which includes a main unit and an atomizing component 100 installed at one end of the main unit. The main unit is used to supply power to the atomizing component 100, and the atomizing component 100 is used to store and heat the aerosol matrix under the power of the main unit's electrical energy, so that the aerosol matrix generates an aerosol for the user to inhale.

[0049] The atomizing assembly 100 includes a mouthpiece 10, a liquid storage housing 30, an inner liquid inlet tube 50, an outer liquid inlet tube 60, and an atomizing core 70. The mouthpiece 10 is connected to one end of the liquid storage housing 30. The inner liquid inlet tube 50 is installed inside the liquid storage housing 30, and the outer liquid inlet tube 60 is installed inside the liquid storage housing 30 and sleeved outside the inner liquid inlet tube 50. The atomizing core 70 is installed inside the liquid storage housing 30 and is located on the flow path of the aerosol matrix flowing into the liquid storage housing 30 through the inner liquid inlet tube 50. The aerosol matrix entering the atomizing core 70 is heated by the main unit's electrical energy to generate aerosol. The aerosol is discharged through the inner liquid inlet tube 50 and the outer liquid inlet tube 60 to the mouthpiece 10 for the user to inhale. It is understood that the specific structure of the atomizing assembly 100 is not limited and can be configured as needed to meet different requirements.

[0050] Specifically, in some embodiments, the liquid storage shell 30 has a hollow shell-like structure and a liquid storage compartment 32 for storing the aerosol matrix. It is understood that the specific construction of the liquid storage shell 30 is not limited and can be configured as needed to meet different requirements.

[0051] The inner liquid inlet pipe 50 is housed in the liquid storage chamber 32 and is connected between the liquid storage chamber 32 and the atomizing core 70. The inner liquid inlet tube 50 is a hollow tubular structure, including an inner liquid inlet tube top wall 52, an inner liquid inlet tube bottom wall, and an inner liquid inlet tube side wall 54 connecting the inner liquid inlet tube top wall 52 and the inner liquid inlet tube bottom wall. The inner liquid inlet tube side wall 54 extends from the edge of the inner liquid inlet tube top wall 52 in the same direction. The inner liquid inlet tube side wall 54 surrounds the inner liquid inlet tube top wall 52 in the circumferential direction to define the atomizing core receiving cavity 53 together with the inner liquid inlet tube side wall 54. The inner liquid inlet tube top wall 52 has an air outlet channel 521 that connects the atomizing core receiving cavity 53 and the external air of the atomizing component 100. The inner liquid inlet bottom wall has an air inlet channel that connects the atomizing core receiving cavity and the external air 53 of the atomizing component 100. The air outlet channel 521, the air inlet channel, and the atomizing core receiving cavity 53 are coaxially arranged.

[0052] Furthermore, at least one liquid inlet hole is provided through the inner liquid inlet pipe sidewall 54, which connects the liquid storage chamber 32 and the atomizing core receiving cavity 53. Therefore, the aerosol matrix in the liquid storage chamber 32 can enter the atomizing core receiving cavity 53 through the liquid inlet hole.

[0053] The atomizing core 70 is housed within the inner liquid inlet tube 50. The atomizing core 70 has a rotating (e.g., cylindrical) structure. The inner wall of the atomizing core 70 forms an atomizing cavity 71 that connects the air inlet channel and the air outlet channel. The central axis of the atomizing core 70 coincides with the central axis of the inner liquid inlet tube 50. Specifically, the atomizing core 70 includes an atomizing core support 72, a substrate 74, and a heating element 76. The atomizing core support 72 has a hollow tubular structure, and its central axis coincides with the central axis of the inner liquid inlet tube 50. The substrate 74 is a porous structure formed of porous ceramic, fiber cotton, or other materials. The substrate 74 is inserted into the upper axial end of the atomizing core support 72, and the substrate 74 circumferentially covers the outer periphery of the atomizing core support 72 to form the atomizing cavity 71. The heating element 76 is housed within the substrate 74 and extends spirally along the axial direction of the atomizing core support 72. Thus, the aerosol matrix entering the atomizing core receiving cavity 53 from the liquid storage chamber 32 is absorbed by the substrate 74, and the heating element 76 can heat the aerosol matrix in the substrate 74 to generate aerosol. External airflow can enter the atomizing cavity 71 through the air inlet channel, and then carry the aerosol out of the atomizing assembly 100 through the air outlet channel 521 of the inner liquid inlet pipe 50.

[0054] As described in the background art, during the use of the atomizing device, the aerosol matrix in the atomizing core receiving cavity 53 is gradually consumed, causing a negative pressure to be generated in the atomizing core receiving cavity 53, which affects the liquid supply rate to the atomizing core 70, and consequently causes the atomizing core 70 to dry burn because the consumption rate of the aerosol matrix is ​​greater than the supply rate.

[0055] Please combine Figure 3 and Figure 4 As shown, in order to avoid the atomizing core 70 from dry burning, in this application, the inner wall of the inner liquid inlet pipe 50 and the atomizing core 70 define a first ventilation channel 90 that connects the air outlet channel 521 and / or the air inlet channel and the liquid storage tank 32.

[0056] Thus, on the one hand, when the liquid in the storage chamber 32 decreases, causing a drop in air pressure within the atomizing core housing cavity 53, the gas in the outlet channel 521 or inlet channel of the inner liquid inlet pipe 50 enters the storage chamber 32 through the first ventilation channel 90 to fill the space freed up by the consumption of the aerosol matrix, thereby balancing the air pressure between the storage chamber 32 and the outside atmosphere and solving the problem of dry burning of the atomizing core 70 caused by aerosol matrix supply compensation. On the other hand, compared to the prior art that relies on the pores and assembly gaps of the substrate 74 itself to form the ventilation channel, the first ventilation channel 90 in this application has a fixed size, thereby forming a stable ventilation pressure and making the ventilation process of the atomizing device highly consistent.

[0057] Specifically, one end face of the atomizing core 70 in the axial direction is spaced apart from the top wall 52 or bottom wall of the inner liquid inlet tube to define and form a first ventilation channel 90, so that gas in the air inlet channel can smoothly enter the first ventilation channel 90. In this way, the installation position of the atomizing core 70 in the atomizing core housing cavity 53 can be controlled to precisely control the size of the first ventilation channel 90.

[0058] The structure of the atomizing assembly 100 will be described below using the example of a first ventilation channel 90, which forms a connecting air outlet channel 521, defined between the atomizing core 70 and the top wall 52 of the inner liquid inlet tube. It can be understood that in some other embodiments, a first ventilation channel 90, which forms a connecting air inlet channel, is defined between the atomizing core 70 and the bottom wall of the inner liquid inlet tube. In other embodiments, air inlet channels are formed between the atomizing core 70 and both the top wall 52 and the bottom wall of the inner liquid inlet tube.

[0059] Specifically, in some embodiments, the atomizing core 70 and the top wall 52 of the inner liquid inlet tube are spaced apart to define and form a first ventilation channel 90, so that the gas in the outlet channel 521 flows out from between the atomizing core 70 and the top wall 52 of the inner liquid inlet tube.

[0060] In some specific embodiments, the surface of the atomizing core 70 facing the top wall 52 of the inner liquid inlet tube has an inwardly recessed groove, the groove wall and the top wall 52 of the inner liquid inlet tube together defining a first ventilation channel 90. It is understood that the shape and position of the groove are not limited and can be set as needed to meet different requirements.

[0061] like Figures 6 to 9 As shown, in some embodiments, the top wall 52 of the inner liquid inlet pipe has an inwardly recessed ventilation groove 5232 on the side facing the atomizing core 70 (e.g., Figure 9 As shown, airflow can flow into the liquid storage tank 32 through the ventilation groove 5232. In this way, since the substrate 74 cannot enter the ventilation groove 5232, the first ventilation channel 90 can be prevented from being compressed by the substrate 74 and affecting the ventilation effect.

[0062] In one embodiment, the ventilation groove 5232 extends radially along the inner liquid inlet pipe 50, and the cross-sectional shape of the ventilation groove 5232 perpendicular to the radial direction of the inner liquid inlet pipe 50 is semi-circular. It is understood that the extension direction and cross-sectional shape of the ventilation groove 5232 are not limited to this and can be configured as needed to meet different requirements.

[0063] In some embodiments, the inner liquid inlet pipe 50 is provided with an inner liquid inlet pipe vent 56 that connects the first ventilation channel 90 and the liquid storage tank 32, and the gas in the first ventilation channel 90 can enter the liquid storage tank 32 through the inner liquid inlet pipe vent 56.

[0064] Specifically, in one embodiment, one end of the inner liquid inlet vent 56 is connected to the first ventilation channel 90, and the other end of the inner liquid inlet vent 56 extends radially along the inner liquid inlet 50 to the outer surface of the inner liquid inlet 50 away from the atomizing core receiving cavity 53. In some embodiments, the cross-sectional shape of the inner liquid inlet vent 56 perpendicular to the radial direction of the inner liquid inlet 50 is circular. It is understood that the extension direction of the inner liquid inlet vent 56 and the shape of the cross-section perpendicular to the radial direction of the inner liquid inlet 50 are not limited to this, and can be configured as needed to meet different requirements.

[0065] In another embodiment, the top wall 52 of the inner liquid inlet tube includes a large end 523 and a small end 525. The large end 523 is connected between the side wall 54 of the inner liquid inlet tube and the small end 525, and the outer diameter of the small end 525 is smaller than the outer diameter of the large end 523, so that the connection between the large end 523 and the small end 525 forms a stepped surface surrounding the small end 525, and the diameter of the air outlet channel 521 is smaller than the diameter of the atomizing core receiving cavity 53.

[0066] The vent 56 of the inner liquid inlet tube includes a first venting section 561 and a second venting section 563. The first venting section 561 extends from the surface of the top wall 52 of the inner liquid inlet tube toward the atomizing core receiving cavity 53 to the surface of the large end 523 of the top wall 52 of the inner liquid inlet tube facing away from the atomizing cavity 53. The second venting section 563 is formed on the surface of the top wall 52 of the inner liquid inlet tube facing away from the atomizing core receiving cavity 53. One end of the second venting section 563 is connected to the first venting section 561, and the other end of the second venting section 563 is connected to the outer edge of the top wall 52 of the inner liquid inlet tube. Specifically, in one embodiment, the first venting section 563 extends to the stepped surface surrounding the small end 525 of the top wall, and the second venting section 563 is located on the stepped surface surrounding the small end 525 of the top wall.

[0067] In one embodiment, the first ventilation section 561 extends along the axial direction of the inner liquid inlet pipe 50, and the cross-section of the first ventilation section 561 perpendicular to the axial direction of the inner liquid inlet pipe 50 is circular. The second ventilation section 563 extends along the radial direction of the inner liquid inlet pipe 50, and the cross-section of the second ventilation section 563 perpendicular to the radial direction of the inner liquid inlet pipe 50 is rectangular. It is understood that the extension direction and cross-sectional shape of the first ventilation section 561 and the second ventilation section 563 are not limited and can be configured as needed to meet different requirements.

[0068] In some embodiments, a second ventilation channel is defined between the inner inlet pipe 50 and the outer inlet pipe 60, connecting the first ventilation channel 90 and the storage tank 32. Specifically, in one embodiment, the outer inlet pipe 60 is provided with a limiting rib 61 extending along the axial direction of the inner inlet pipe 50 and surrounding the outer side of the inner inlet pipe 50. The limiting rib 61 and the outer circular surface of the inner inlet pipe sidewall 54 define a second ventilation channel 63. Therefore, the gas discharged from the inner inlet pipe ventilation hole 56 of the inner inlet pipe 50 enters the storage tank 32 through the second ventilation channel 63.

[0069] It is understood that in another embodiment, it is not necessary to form a second ventilation channel 63 between the inner liquid inlet pipe 50 and the outer liquid inlet pipe 60, and the gas discharged from the inner liquid inlet pipe ventilation hole 56 of the inner liquid inlet pipe 50 directly enters the liquid storage tank 32.

[0070] In the above embodiments, the dimensions and lengths of the first ventilation channel 90, the ventilation hole 56 of the inner liquid inlet pipe, and the second ventilation channel 63 are set according to the dimensions of components such as the inner liquid inlet pipe 50, as long as the ventilation pressure of the first ventilation channel 90, the ventilation hole 56 of the inner liquid inlet pipe, and the second ventilation channel 63 reaches a preset value. It should be noted that the ventilation pressure is the pressure that external gas needs to overcome to enter the liquid storage tank 32 through the first ventilation channel 90, the ventilation hole 56 of the inner liquid inlet pipe, and the second ventilation channel 63. During the consumption of the aerosol matrix, when the pressure drop in the liquid storage tank 32 exceeds the ventilation pressure, external gas can enter the liquid storage tank 32 through the first ventilation channel 90, the ventilation hole 56 of the inner liquid inlet pipe, and the second ventilation channel 63.

[0071] Specifically, the ventilation pressure is the sum of the driving pressure required by the friction resistance ΔP, surface tension h, and liquid level pressure. The formula for calculating the friction resistance is: (Where, f is the laminar flow interval, l is the channel length, d is the equivalent diameter, v is the average flow velocity, ρ is the liquid density, and Re is the Reynolds number), the formula for calculating surface tension is: (Where, γ is the surface tension, θ is the contact angle, ρ is the liquid density, g is the gravitational acceleration, and r is the flow channel radius).

[0072] Please see Figures 1 to 5In the first embodiment of this application, the atomizing assembly 100 has a gap between one end face of the atomizing core 70 in the axial direction and the top wall 52 of the inner liquid inlet tube to form a first ventilation channel 90. The ventilation port 56 of the inner liquid inlet tube includes a first ventilation section 561 and a second ventilation section 563. The first ventilation section 561 extends from the side surface of the top wall 52 of the inner liquid inlet tube toward the atomizing core receiving cavity 53 to the side surface of the large end 523 of the top wall of the inner liquid inlet tube away from the atomizing core receiving cavity 53. The second ventilation section 563 is formed on the outer surface of the large end 523 of the top wall surrounding the small end 525 of the top wall. One end of the second ventilation section 563 is connected to the first ventilation section 561, and the other end of the second ventilation section 563 is connected to the outer edge of the top wall 52 of the inner liquid inlet tube.

[0073] Specifically, one end face of the atomizing core 70 in the axial direction has a 0.2mm gap with the top wall 52 of the inner liquid inlet tube to form a first ventilation channel 90 with a height of 0.2mm. The first ventilation section 561 of the ventilation hole 56 of the inner liquid inlet tube is a circular hole with a diameter of 0.2mm, and the second ventilation section 563 is a square groove with a width of 0.2mm and a depth of 0.2mm. Thus, according to the calculation formula of ventilation pressure, the ventilation pressure of the atomizing component 100 of the first embodiment can be calculated to be 1074 to 1154 Pa, thereby achieving a good ventilation effect.

[0074] Please see Figures 6 to 10 In the second embodiment of this application, the atomizing assembly 100 has a gap between one end face of the atomizing core 70 in the axial direction and the top wall 52 of the inner liquid inlet tube to form a first ventilation channel 90. A recessed ventilation groove 5232 is formed on the side surface of the top wall 52 of the inner liquid inlet tube facing the atomizing core 70. One end of the ventilation hole 56 of the inner liquid inlet tube is connected to the first ventilation channel 90, and the other end of the ventilation hole 56 extends radially along the inner liquid inlet tube 50 to the outer surface of the inner liquid inlet tube 50 away from the atomizing core receiving cavity 53.

[0075] Specifically, there is a 0.15mm gap between the area on one end face of the atomizing core 70 where the ventilation groove 5232 is not formed and the top wall 52 of the inner liquid inlet tube. The cross-section of the ventilation groove 5232 is semi-circular, and the radius of the ventilation groove 5232 is 0.15mm. Therefore, the atomizing core 70 and the inner liquid inlet tube 50 together form a first ventilation channel 90 with a maximum inner diameter of 0.3mm. The ventilation hole 56 of the inner liquid inlet tube is a circular hole with a diameter of 0.2mm-0.5mm. Thus, according to the calculation formula of ventilation pressure, the ventilation pressure of the atomizing component 100 of the second embodiment can be calculated to be 964 to 1034 Pa.

[0076] Please see Figures 11 to 14In the third embodiment of this application, there is a gap between one end face of the atomizing core 70 in the axial direction and the top wall 52 of the inner liquid inlet tube to form a first ventilation channel 90. One end of the ventilation hole 56 of the inner liquid inlet tube is connected to the first ventilation channel 90, and the other end of the ventilation hole 56 of the inner liquid inlet tube extends along the radial direction of the inner liquid inlet tube 50 to the outer surface of the inner liquid inlet tube 50 away from the atomizing core receiving cavity 53.

[0077] Specifically, there is a 0.3mm gap between one end face of the atomizing core 70 and the top wall 52 of the inner liquid inlet tube to form a first ventilation channel 90 with a height of 0.3mm, and the ventilation hole 56 of the inner liquid inlet tube is a circular hole with a diameter of 0.2mm-0.5mm.

[0078] The aforementioned atomizing component 100 and the atomizing device equipped with it, through the fixedly installed first ventilation channel 90, inner liquid inlet pipe ventilation hole 56, and second ventilation channel 63, provide the atomizing component 100 with a highly consistent ventilation pressure. This avoids the influence of assembly tolerances and the compression of the substrate 74 on the ventilation pressure, improves the ventilation performance of the atomizing device, and effectively avoids the risks of leakage and dry burning.

[0079] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0080] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
