Description

Technical Field

[0001] This invention belongs to the field of burner technology, specifically relating to a burner with a single-layer pot rack. Background Technology

[0002] Gas stoves, as a convenient and quick cooking appliance, have become widespread in the kitchens of countless households. Gas stove burners utilize liquefied petroleum gas, manufactured gas, natural gas, and other gaseous fuels for direct-fire heating, thus rapidly heating cooking utensils. The components of a typical burner generally include the burner itself (comprising the burner head, gas distribution plate, and flame cap), a control valve, an igniter, and an injector. The working process involves gas supplied by an external gas pipe or gas cylinder being delivered to the burner via the control valve and injector. The igniter then ignites the gas at the burner to generate heat. Existing outer flame caps have one or more rows of flame holes on their outer wall, while the inner wall of the outer flame cap has no flame holes. The inner flame relies solely on the flame holes on the inner flame cap of the burner to form an inner ring flame. Furthermore, the outer wall of the outer flame cap is generally a circular surface, resulting in a small number of flame holes, a small flame area, and generally low combustion efficiency and incomplete combustion. Existing patent documents disclose a utility model patent for an easy-to-ignite outer ring flame cap and burner (publication number: CN217540742U). The technical solution describes that a row of flame holes is provided on the outer side wall of the outer flame cap, but no flame holes are provided on the inner side wall of the outer flame cap. The overall combustion efficiency is generally low and the combustion is incomplete, which also has the above-mentioned technical problems. Summary of the Invention

[0003] The purpose of this invention is to provide a technical solution for a burner with a single-layer pot frame, addressing the shortcomings of existing technologies. The structure is ingeniously and rationally designed, highly practical. The outer ring burner cap utilizes the cooperation of inner and outer ring flame outlets to form two gas flow streams, enhancing the mixing degree of gas and air and improving the combustion efficiency of the burner. Simultaneously, it creates two rings of flame on the outer ring burner cap, further improving the thermal efficiency of the burner. Furthermore, the inner ring flame outlet is located in a first groove, and the outer ring flame outlet is located in a second groove. This groove design increases the flame area at the flame outlets, making flame lift-off less likely and resulting in more complete combustion. The pot frame is also designed with a novel structure, convenient assembly and disassembly, good energy concentration, and high practicality.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A burner with a single-layer pot rack includes: a burner head, a base, a flame distribution cover and a pot rack, wherein the base is disposed on the burner head and the flame distribution cover is disposed on the base, and the flame distribution cover includes an outer ring flame cover and an inner ring flame cover.

[0006] The feature is that: the outer ring flame cover includes a top wall, an inner side wall and an outer side wall, and an inner inclined surface is connected between the top wall and the inner side wall. A groove group 1 is provided on the inner inclined surface. The groove group 1 includes at least one groove 1, and an inner ring flame outlet hole is provided in the groove 1.

[0007] An outer inclined surface connects the top wall and the outer side wall. A second groove group is provided on the outer inclined surface. The second groove group includes at least one second groove. An outer ring fire outlet hole is provided in the second groove.

[0008] The combination of inner and outer ring flame outlets creates two gas flow streams, enhancing the mixing of gas and air and improving the combustion efficiency of the burner. At the same time, it creates two rings of flame on the outer ring burner cap, improving the thermal efficiency of the burner. The inner ring flame outlet is located in groove one, and the outer ring flame outlet is located in groove two. The groove design increases the flame area at the flame outlet, making it less prone to flame lift-off.

[0009] The pot rack includes an energy-concentrating ring seat, a support ring, and support feet. The support ring can be detachably installed inside the energy-concentrating ring seat, and the support feet are distributed circumferentially on the support ring. The pot rack has a novel structure, is easy to assemble and disassemble, has a good energy-concentrating effect, and is highly practical. The energy-concentrating ring seat has a bowl-shaped structure that is larger at the top and smaller at the bottom. The structure is simple, has a large energy-concentrating range, and has a good effect, effectively reducing heat loss.

[0010] Furthermore, the first groove group is provided with at least two groups, and several first groove groups are distributed circumferentially along the inner inclined surface. The first groove group is distributed circumferentially on the inner inclined surface, and the first groove group is preferably evenly distributed circumferentially on the inner inclined surface to ensure the uniformity of the arrangement of the inner ring flame holes, thereby forming a stable inner ring flame and achieving uniform heating.

[0011] The groove group two is provided in at least two sets, and several groove groups two are distributed circumferentially along the outer inclined surface. The groove groups two are circumferentially distributed on the outer inclined surface, and the groove groups two are preferably evenly distributed circumferentially on the outer inclined surface to ensure the uniformity of the arrangement of the outer ring flame holes, thereby forming a stable outer ring flame, achieving uniform heating, and forming an anti-burn zone between adjacent groove groups two, so that the outer flame can avoid the pot rack, thereby preventing the pot claws of the pot rack from being burned, reducing heat loss, and reducing the carbon monoxide content in the combustion products.

[0012] Furthermore, the outer wall, outer slope, top wall, inner slope, and inner side wall are sequentially connected to form a mixing chamber at the bottom of the outer ring flame cap. The inner and outer ring flame outlets are connected to the mixing chamber. A reinforcing protrusion is provided in the mixing chamber, and the inner ring flame outlet passes through the reinforcing protrusion. Gas and air are mixed in the mixing chamber and buffered there. The inner and outer ring flame outlets are connected to the mixing chamber, allowing the gas in the mixing chamber to enter the inner and outer ring flame outlets. The design of the reinforcing protrusion can enhance the overall structural strength of the outer ring flame cap, improve its quality, and extend its service life. Moreover, the inner ring flame outlet passes through the reinforcing protrusion, making it less likely for the outer ring flame cap to break during the machining of the inner ring flame outlet, thus facilitating the manufacturing of the outer ring flame cap.

[0013] The reinforcing protrusions are distributed circumferentially in the mixing chamber, and a guide groove is formed between two adjacent reinforcing protrusions. The reinforcing protrusions are circumferentially distributed in the mixing chamber, and preferably the reinforcing protrusions are evenly distributed circumferentially in the mixing chamber, which improves the structural stability and firmness of the entire outer ring flame cap. The guide groove is formed between adjacent reinforcing protrusions, which can better guide the gas to the outer ring flame outlet, improve the combustion efficiency of the outer ring flame cap, and also play a role in stabilizing the flame.

[0014] Furthermore, a flame transfer groove is provided on the outer ring flame cap. The flame transfer groove is used to conduct flame to the outer ring flame outlet. The flame transfer groove is located on the surface of the outer ring flame cap, which shortens the connection path between the inner ring flame outlet and the outer ring flame outlet. This is more conducive to the transmission of flame from the inner side to the outer side, improves the reliability of flame transmission, and makes the flame transmission effect better, faster and shorter.

[0015] Flame transfer holes are provided on both sides of the flame transfer groove. The groove adjacent to the flame transfer hole is a blind groove. The groove is designed as a blind groove and does not have an inner ring flame outlet hole. This improves the structural strength of the outer ring flame cap where the flame transfer groove and flame transfer hole are located and extends the service life of the outer ring flame cap. The flame transfer holes are located on both sides of the flame transfer groove, and preferably they are symmetrically arranged on both sides of the flame transfer groove. This makes the gas flow above the end of the flame transfer groove stable, which makes the flame combustion more stable and improves the flame quality. The flame transfer holes are located close to the inner wall of the outer ring flame cap, so that the flame transfer groove can transfer the flame at the flame transfer hole to the outside of the outer ring flame cap and ignite the outer ring flame outlet hole, making the flame transfer more stable and reliable.

[0016] Furthermore, the outer ring flame outlet includes outer ring flame outlet one and outer ring flame outlet two. The diameter of outer ring flame outlet one is larger than the diameter of outer ring flame outlet two. Outer ring flame outlet one and outer ring flame outlet two are distributed vertically within groove two, which is a reasonable design. The design of outer ring flame outlet one and outer ring flame outlet two results in two rows of outer ring flame outlets on the outer side of the outer ring flame cap. The upper outer ring flame outlet one is the main combustion flame outlet, and the lower outer ring flame outlet two is the main flame stabilizing flame outlet, thus making the outer flame more stable.

[0017] Furthermore, a positioning protrusion is provided at the bottom of the outer ring burner cap. The positioning protrusion includes positioning protrusion one and positioning protrusion two. Positioning protrusion one is located near the outer wall of the outer ring burner cap, and positioning protrusion two is located near the inner wall of the outer ring burner cap. Positioning protrusion one and positioning protrusion two can cooperate with the base to facilitate the installation and positioning of the outer ring burner cap on the base. The two positioning protrusions are respectively located close to the inner and outer walls of the outer ring burner cap, so that the two positioning protrusions are located at the two sides of the mixing chamber. Positioning protrusion one and positioning protrusion two can also play a sealing role, effectively preventing the mixed gas in the mixing chamber from overflowing from the connection gap between the outer ring burner cap and the base, thus improving the safety of use.

[0018] Furthermore, the inner circumference of the energy-concentrating ring seat has an integrally molded support section, and the bottom of the bracket ring is provided with a corresponding slot. The bracket ring is locked onto the support section by the slot, making it easy to install and use, easy to replace, simple to operate, labor-saving and convenient. By locking the support section by the slot, the bracket ring is placed on the support section, and the circumference is restricted in many places, so the bracket ring cannot move freely, resulting in high installation stability. Moreover, the support section and the energy-concentrating ring seat are integrated, and the connection between the two is not easy to crack, the structure is more resistant to lateral impact, and is not easy to deform.

[0019] Furthermore, the support extends downward to form a support leg, and a ventilation area is formed between the support leg and the bottom of the energy-concentrating ring seat. The support leg has a downward protrusion, which facilitates the passage of air and its flow to the center of the boiler rack, thereby supplementing the air and promoting complete combustion of the gas. The downward protrusion contacts the placement surface, increasing the height difference between the energy-concentrating ring seat and the placement surface, thereby increasing the ventilation area, ensuring sufficient airflow, and further contributing to complete combustion of the gas.

[0020] The legs and the support are located in the same vertical plane. The legs transfer the pressure of the cookware downward to the support ring, while the support provides support to the support ring located directly below the legs, offsetting the downward pressure and preventing the part from deforming due to excessive pressure or prolonged exposure, thereby extending the service life of the support ring.

[0021] Furthermore, an inner ring is provided on the inner side of the energy-concentrating ring seat, which connects to the support part, increasing the contact area between the energy-concentrating ring seat and the support part, improving the connection strength, and making the entire structure more stable.

[0022] Furthermore, the energy-concentrating ring seat is provided with an integrally molded shielding part, which is located on the extension line of the extension direction of the bracket leg. The shielding part provides lateral protection for the bracket leg, preventing external forces from directly impacting the bracket leg and affecting the installation stability of the bracket ring. Moreover, the shielding part and the energy-concentrating ring seat are integrated, and the connection between the two is not easy to crack, the structure is stable, more resistant to lateral impact, and not easy to deform.

[0023] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0024] This invention features a clever and reasonable structural design with strong practicality. The outer ring burner cap utilizes the cooperation of the inner and outer ring flame outlets to form two gas flow streams, enhancing the mixing degree of gas and air and improving the combustion efficiency of the burner. At the same time, it creates two rings of flame on the outer ring burner cap, improving the thermal efficiency of the burner. Furthermore, the inner ring flame outlet is located in groove one, and the outer ring flame outlet is located in groove two. The design of the grooves increases the flame area at the flame outlet, making it less prone to flame lift-off and resulting in more complete combustion. In addition, the pot rack is designed with a novel structure, convenient assembly and disassembly, good energy concentration, and strong practicality. Attached Figure Description

Detailed Implementation

[0040] like Figures 1 to 13 As shown, this invention discloses a burner with a single-layer pot rack, comprising a burner head 1, a base 2, a flame distribution cover, and a pot rack 25. The base 2 is disposed on the burner head 1, and the flame distribution cover is disposed on the base 2. The flame distribution cover includes an outer ring flame cover 3 and an inner ring flame cover 4. The outer ring flame cover 3 includes a top wall 5, an inner side wall 7, and an outer side wall 6. An inner inclined surface 8 connects the top wall 5 and the inner side wall 7. A groove group 1 9 is provided on the inner inclined surface 8. The groove group 1 9 includes at least one groove 23. An inner ring flame outlet hole 10 is provided in the groove 23. An outer inclined surface 11 connects the top wall 5 and the outer side wall 6. A groove group 2 12 is provided on the outer inclined surface 11. The groove group 2 12 includes at least one groove 24. An outer ring flame outlet hole is provided in the groove 24.

[0041] The inner ring flame outlet 10 and the outer ring flame outlet are combined to form two gas flow streams, which enhances the mixing degree of gas and air and improves the combustion efficiency of the burner. At the same time, it forms two ring flames on the outer ring flame cap 3, which improves the thermal efficiency of the burner. The inner ring flame outlet 10 is located in the first groove 23 and the outer ring flame outlet is located in the second groove 24. The design of the grooves can increase the flame area at the flame outlet, making it less likely to cause flame lift-off, and the flame formation is more stable, which effectively improves the combustion thermal efficiency and improves energy efficiency.

[0042] At least two sets of groove groups 9 are provided, with several groove groups 9 distributed circumferentially along the inner inclined surface 8. The groove groups 9 are circumferentially distributed on the inner inclined surface 8, and preferably, the groove groups 9 are evenly distributed circumferentially on the inner inclined surface 8 to ensure the uniformity of the arrangement of the inner ring flame holes 10, thereby forming a stable inner ring flame and achieving uniform heating. At least two sets of groove groups 22 are provided, with several groove groups 22 distributed circumferentially along the outer inclined surface 11. The groove groups 22 are circumferentially distributed on the outer inclined surface 11, and preferably, the groove groups 22 are evenly distributed circumferentially on the outer inclined surface 11 to ensure the uniformity of the arrangement of the outer ring flame holes, thereby forming a stable outer ring flame and achieving uniform heating. Furthermore, an anti-burn zone 22 is formed between adjacent groove groups 22, allowing the outer flame to avoid the pot frame 25, thereby preventing the pot claws of the pot frame 25 from being burned, reducing heat loss, and lowering the carbon monoxide content in the combustion products.

[0043] The outer wall 6, outer inclined surface 11, top wall 5, inner inclined surface 8, and inner side wall 7 are sequentially connected to form a mixing chamber 14 at the bottom of the outer ring flame cap 3. The inner ring flame outlet 10 and the outer ring flame outlet are both connected to the mixing chamber 14. A reinforcing protrusion 15 is provided in the mixing chamber 14. The inner ring flame outlet 10 passes through the reinforcing protrusion 15. Gas and air are mixed in the mixing chamber 14 and buffered in the mixing chamber 14. The inner ring flame outlet 10 and the outer ring flame outlet are both connected to the mixing chamber 14, so that the mixed gas in the mixing chamber 14 can enter the inner ring flame outlet 10 and the outer ring flame outlet. The design of the reinforcing protrusion 15 can enhance the overall structural strength of the outer ring flame cap 3, improve the quality of the outer ring flame cap 3, and extend the service life of the outer ring flame cap 3. Moreover, the inner ring flame outlet 10 passes through the reinforcing protrusion 15, so that the outer ring flame cap 3 is not easy to break during the processing of the inner ring flame outlet 10, thus facilitating the processing and manufacturing of the outer ring flame cap 3.

[0044] The reinforcing protrusions 15 are distributed circumferentially along the mixing chamber 14, and a guide groove 16 is formed between two adjacent reinforcing protrusions 15. The reinforcing protrusions 15 are circumferentially distributed in the mixing chamber 14, and preferably the reinforcing protrusions 15 are evenly distributed circumferentially in the mixing chamber 14, which improves the structural stability and firmness of the entire outer ring flame cap 3. The guide groove 16 is formed between adjacent reinforcing protrusions 15, which can better guide the gas to the outer ring flame outlet, improve the combustion efficiency of the outer ring flame cap 3, and also play a role in stabilizing the flame.

[0045] The inner inclined surface 8 extends downward from the inner edge of the top wall 5 to the inner side wall 7, and is inclined downward towards the center of the outer ring burner cap 3. The outer inclined surface 11 extends downward from the outer edge of the top wall 5 to the outer side wall 6, and is inclined downward away from the center of the outer ring burner cap 3. The inner inclined surface 8 and the outer inclined surface 11 can be straight or curved, which is simple and reasonable. The inner inclined surface 8 and the outer inclined surface 11 can be adjusted to be straight or curved according to actual design requirements. The inclined surface design of the outer inclined surface 11 can guide the secondary air well, reduce the smoke generated at the outer ring burner hole, and improve the combustion efficiency. In this application, the inner inclined surface 8 is preferably designed as a curved surface to ensure the energy-gathering effect inside the outer ring burner cap 3. The inner inclined surface 8 and the outer inclined surface 11 are not limited to being straight or curved surfaces, but can also be a combination of straight lines and curves.

[0046] The outer ring flame cap 3 is provided with a flame transfer groove 13, which is used to conduct flame to the outer ring flame outlet. The flame transfer groove 13 is located on the surface of the outer ring flame cap 3, which shortens the connection path between the inner ring flame outlet 10 and the outer ring flame outlet, which is more conducive to the transmission of flame from the inner side to the outer side, improves the reliability of flame transmission, and makes the flame transmission effect good, fast and short. The cross-sections of the inner ring flame outlet 10 and the outer ring flame outlet can be circular, polygonal or irregular shapes, etc.

[0047] Flame transfer holes 17 are provided on both sides of the flame transfer groove 13. The groove 23 adjacent to the flame transfer hole 17 is a blind groove. The groove 23 adjacent to the flame transfer hole 17 is designed as a blind groove. No inner ring flame outlet hole 10 is provided on the groove 23, thereby improving the structural strength of the outer ring flame cap 3 where the flame transfer groove 13 and the flame transfer hole 17 are located, and extending the service life of the outer ring flame cap 3. The flame transfer holes 17 are located on both sides of the flame transfer groove 13, and the flame transfer holes 17 are preferably symmetrically arranged on both sides of the flame transfer groove 13, so that the gas flow formed above the end of the flame transfer groove 13 is stable, thereby making the flame combustion more stable and improving the flame quality. The flame transfer holes 17 are located close to the inner side wall 7 of the outer ring flame cap 3, so that the flame transfer groove 13 can transfer the flame at the flame transfer hole 17 to the outside of the outer ring flame cap 3, igniting the outer ring flame outlet hole, making the flame transfer more stable and reliable.

[0048] The outer ring flame outlet is inclined on the outer inclined surface 11. The outer ring flame outlet is inclined downward from the outside of the outer ring flame cap 3 into the mixing chamber 14. The design is ingenious and reasonable. This design makes the end of the outer ring flame outlet that connects to the mixing chamber 14 lower than the flame outlet end of the outer ring flame outlet. This is roughly the same as the upward direction of gas transmission, which is more conducive to the transmission of gas into the outer ring flame outlet and makes the flame conduction more reliable.

[0049] The outer ring flame outlets include outer ring flame outlet one 18 and outer ring flame outlet two 19. The diameter of outer ring flame outlet one 18 is larger than the diameter of outer ring flame outlet two 19. Outer ring flame outlet one 18 and outer ring flame outlet two 19 are distributed vertically within groove two 24, which is a reasonable design. The design of outer ring flame outlets using outer ring flame outlet one 18 and outer ring flame outlet two 19 forms two rows of outer ring flame outlets on the outer side of the outer ring flame cap 3. At the same time, since the diameter of outer ring flame outlet one 18 is larger than the diameter of outer ring flame outlet two 19, the upper outer ring flame outlet one 18 is the main combustion flame outlet, and the lower outer ring flame outlet two 19 is the main flame stabilizing flame outlet, thus making the outer flame more stable. Outer ring flame outlet one 18 and outer ring flame outlet two 19 can be distributed symmetrically vertically or staggered vertically.

[0050] The bottom of the outer ring burner cap 3 is provided with positioning protrusions, including positioning protrusion 1 20 and positioning protrusion 21. Positioning protrusion 1 20 is located near the outer side wall 6 of the outer ring burner cap 3, and positioning protrusion 21 is located near the inner side wall 7 of the outer ring burner cap 3. Positioning protrusion 1 20 and positioning protrusion 21 can cooperate with the base 2 to facilitate the installation and positioning of the outer ring burner cap 3 on the base 2. The two positioning protrusions are respectively located close to the inner and outer side walls 6 of the outer ring burner cap 3, so that the two positioning protrusions are located at the two side edges of the mixing chamber 14. Positioning protrusion 1 20 and positioning protrusion 21 can also play a sealing role, effectively preventing the mixed gas in the mixing chamber 14 from overflowing from the connection gap between the outer ring burner cap 3 and the base 2, thus improving the safety of use.

[0051] The pot rack 25 includes an energy-concentrating ring seat 27, a support ring 26, and support legs 28. The support ring 26 is detachably installed inside the energy-concentrating ring seat 27, and the support legs 28 are circumferentially distributed on the support ring 26. Preferably, the support legs 28 are evenly distributed circumferentially on the support ring 26 to improve the overall structural balance and stability. The pot rack 25 has a novel structure, is easy to assemble and disassemble, has a good energy-concentrating effect, and is highly practical. The energy-concentrating ring seat 27 has a bowl-shaped structure that is larger at the top and smaller at the bottom. It has a simple structure, a large energy-concentrating range, and a good effect, effectively reducing heat loss. The energy-concentrating ring seat 27 surrounds the support ring 26, which not only protects it from direct impact but also concentrates heat and reflects it back to the bottom of the pot, thereby improving heating efficiency and reducing heat loss.

[0052] The energy-concentrating ring seat 27 has an integrally formed support part 29 distributed in the inner circumference. The bottom of the bracket ring 26 is provided with a corresponding slot 31. The bracket ring 26 is limited and locked onto the support part 29 by the slot 31. It can be installed and used immediately, is easy to replace, and is simple to operate, saving effort and convenience. By locking the support part 29 by the slot 31, the bracket ring 26 is placed on the support part 29. The bracket ring 26 is restricted in many places in the circumference and cannot move freely, resulting in high installation stability. Moreover, the support part 29 and the energy-concentrating ring seat 27 are integrated, and the connection between the two is not easy to crack. The structure is stable, more resistant to lateral impact, and not easy to deform.

[0053] The slot 31 is located directly below the bracket 28. After the bracket ring 26 is installed, the bracket 28 and the support part 29 are located in the same vertical plane. The bracket 28 transmits the pressure of the pot downward to the bracket ring 26. The support part 29 provides support to the bracket ring 26 located directly below the bracket 28, offsetting the downward pressure and preventing the part from deforming due to excessive pressure or long time, thereby extending the service life of the bracket ring 261.

[0054] An inner ring 30 is provided on the inner side of the energy-concentrating ring seat 27. The inner ring 30 is connected to the support part 29, which increases the contact area between the energy-concentrating ring seat 27 and the support part 29, improves the connection strength, and makes the whole structure more stable.

[0055] The support 29 extends downward to form a support leg 32. A ventilation area is formed between the support leg 32 and the bottom of the energy-concentrating ring seat 27. The support leg 32 has a downward protrusion 33, which facilitates the passage of air and its flow to the center of the boiler rack 25, thereby supplementing the air and promoting complete combustion of the gas. The downward protrusion 33 contacts the placement surface, increasing the height difference between the energy-concentrating ring seat 27 and the placement surface, thereby increasing the ventilation area, ensuring sufficient airflow, and further promoting complete combustion of the gas.

[0056] The energy-concentrating ring seat 27 is provided with an integrally formed shielding part 34. The shielding part 34 is located on the extension line of the extension direction of the bracket leg 28. The shielding part 34 provides lateral protection for the bracket leg 28, preventing external forces from directly impacting the bracket leg 28 and affecting the installation stability of the bracket ring 26. Moreover, the shielding part 34 and the energy-concentrating ring seat 27 are integrated, and the connection between the two is not easy to crack, the structure is stable, more resistant to lateral impact, and not easy to deform.

[0057] This invention features a clever and reasonable structural design with strong practicality. The combination of the inner and outer ring flame outlets 10 creates two gas flow streams, enhancing the mixing of gas and air and improving the burner's combustion efficiency. Simultaneously, it forms two rings of flame on the outer ring burner cap, further improving the burner's thermal efficiency. The inner ring flame outlet 10 is located within groove 23, and the outer ring flame outlet is located within groove 24. This groove design increases the flame area at the outlets, reducing the likelihood of flame lift-off and ensuring more complete combustion. Furthermore, the pot support 25 is designed with a novel structure, is easy to assemble and disassemble, has good energy concentration, and is highly practical.

[0058] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to achieve substantially the same technical effect are all covered within the protection scope of the present invention.
