[0045] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0046] like Figures 1 to 13 As shown, a combination assembly of a gas pipe and a gas switch valve includes a gas pipe 1, and also includes a single-outlet simple valve and a double-outlet simple valve; the single-outlet simple valve and the double-outlet simple valve are respectively connected to the gas pipe 1; the single-outlet simple valve and the double-outlet simple valve each include a valve body and a valve cover; the valve body has an air inlet 3; the distance from the central axis of the air inlet 3 to the rear end surface of the valve cover is L; the distance L is 28-35mm, preferably, the distance L is 30-33mm; the specific distance L can be 30mm, 31mm, 32mm, 33mm; the distance between the central axis of the valve body and the central axis of the gas pipe 1 is D; the distance D is 15-20mm, preferably, the distance D is 16-18mm, and the specific distance D can be 17mm or 18mm.

[0047] The combined assembly of the gas pipe and the gas switch valve is provided by combining the gas pipe 1, the single-outlet simple valve and the double-outlet simple valve, rationally designing the distance from the central axis of the air inlet 3 to the rear end surface of the valve cover, as well as the distance between the central axis of the valve body and the central axis of the gas pipe 1, rationally designing the size range between the gas pipe 1 and the valve body, and the size range between the air inlet 3 and the valve cover, so as to better optimize the spatial structure of the structure in the horizontal and vertical directions, make the overall structure more compact, and miniaturize the volume design to avoid the structure from occupying too much space, so that it can easily adapt to various narrow installation environments and improve the space utilization of the structure. It can better realize the close arrangement of single-outlet simple valves and double-outlet simple valves on the same panel without the need for additional structural auxiliary fixation, thereby achieving structural simplicity, which not only simplifies the installation process and facilitates installation and maintenance, but also improves the overall aesthetics and neatness of the equipment, so that the combined assembly of the gas pipe and the gas switch valve can be widely used in various gas equipment, such as gas stoves, gas water heaters, etc., with good versatility and practicality; at the same time, it also fully considers the manufacturing cost factor, the reduction in material usage, and the simplification of the production process, all of which effectively reduce the manufacturing cost and are more suitable for promotion in the market.

[0048] To facilitate the stable installation of the single-outlet and dual-outlet simple valves on the gas pipe 1, a pipe clamp structure 2 is connected between the valve body corresponding to the air inlet 3 and the gas pipe 1. The pipe clamp structure 2 can include an upper pipe clamp, a lower pipe clamp, and screws. The upper pipe clamp is installed on the valve body and clamped onto the gas pipe 1. The lower pipe clamp is then clamped onto the gas pipe 1 from below. The upper and lower pipe clamps are connected together by screws, thus facilitating the stable installation of the single-outlet and dual-outlet simple valves on the gas pipe 1.

[0049] In this embodiment, the single-outlet simple valve can be the first single-outlet valve 4, the second single-outlet valve 5 or the third single-outlet valve 6; the double-outlet simple valve can be the fourth double-outlet valve 7, the fifth double-outlet valve 8, the sixth double-outlet valve 9 or the seventh double-outlet valve 10.

[0050] For a simple valve with a single air outlet, in this embodiment, Figure 4As shown, the single-outlet simple valve is a first single-outlet valve 4; the valve body and valve cover are respectively the first valve body 41 and the first valve cover 42; the first single-outlet valve 4 also includes a first valve core 43, a first rotating shaft 44, a first limiting plate 45, a first spring 46 and a nozzle 47; the first valve body 41 has a first valve core cavity 411 connected to the air inlet 3; the first valve core 43 is rotatably installed in the first valve core cavity 411; the first valve core 43 is connectable to the air inlet 3; the first rotating shaft 44 is mounted on the first valve cover 42; the front end of the first rotating shaft 44 is covered with a first limiting plate 45 and a first spring 46, and is rotatable and slidably connected to the valve core in the front and rear directions relative to the valve core; the nozzle 47 is connected to the first valve body 41 and is connected to the inner cavity of the first valve core 43. Specifically, a card-embedding groove is provided on the rear end of the first valve core 43; the front end of the rotating shaft can be slidably embedded in the card-embedding groove; the front end of the rotating shaft has a card-embedding head that can be adapted to be slidably embedded in the card-embedding groove; the card-embedding head can reciprocate in the front and rear directions relative to the first valve core 43 in the card-embedding groove; the card-embedding head is covered with the first limit plate; the first limit plate 45 is provided with a limit clamping part; the first valve cover 42 is provided with a limit groove for limiting and clamping the first limit plate 45 and a rotation adjustment groove that is connected to the limit groove and is located in front of the limit groove; the limit clamping part is adapted to and embedded in the limit groove and slides with the rotation adjustment groove; the front end of the first spring 46 is sleeved on the rear end of the first valve core 43, and the rear end of the second spring is sleeved on the card-embedding head and tops the first limit plate 45. During use, the first rotating shaft 44 is pushed forward relative to the first valve body 41, and the limit plate moves synchronously with the rotating shaft, entering the rotation adjustment groove from the limit groove. The first spring 46 is compressed, and the locking head of the rotating shaft is locked into the locking slide groove. The rotation adjustment groove is rotated and adjusted to connect the air inlet 3 with the inner cavity of the first valve core 43. The gas passes through the air inlet 3 and the inner cavity of the valve core and then flows out from the nozzle 47, which is convenient for the user. After use, the rotating shaft is rotated and adjusted, and the limit clamping portion on the first limit plate 45 is aligned with the position of the limit groove. The first spring 46 is reset, pushing the rotating shaft to move back relative to the valve core and reset, and the limit clamping portion of the first limit plate 45 returns to the limit groove. With this design, the first single-outlet valve 4 has a simple structure, is easy to operate, and has a single air outlet for gas discharge, which is convenient for the user.

[0051] In another embodiment substantially the same as the first outlet valve, Figures 4 and 5As shown, the nozzle 47 is replaced with a screw connector 51; that is, the first valve body 41 and the first valve cover 42, the first valve core 43, the first rotating shaft 44, the first limit plate 45, the first spring 46 and the screw connector 51 are combined to form a second air outlet valve that is basically the same as the first air outlet valve. The screw connector 51 is connected to the first valve body 41 and is connected to the inner cavity of the first valve core 43; the first valve cover 42 is provided with a micro switch 52 that drives the first rotating shaft 44 to move and rotate. The operating principle of the second air outlet valve is the same as that of the first air outlet valve. The nozzle 47 is replaced with a screw connector 51, which facilitates the connection of the screw connector 51 with other pipes. At the same time, the addition of a micro switch 52 on the first valve cover 42 can automatically realize the rotation and movement of the rotating shaft, thereby improving the convenience of the structure. The single air outlet is more convenient for users to use.

[0052] In this embodiment, if Figure 6As shown, the single-outlet simple valve can be a third single-outlet valve 6; the valve body and valve cover are respectively a third valve body 61 and a third valve cover 63; the third single-outlet valve 6 also includes a third valve core 64, a third rotating shaft 65, a third limit plate 66, a third spring 67, a third push rod 68, a third solenoid valve assembly 69 and an air outlet pipe 610; the third valve body 61 has a third valve core cavity 611 connected to the air inlet 3, and a ventilation cavity 62 connected to the front end of the third valve core cavity 611; the third valve core 64 is rotatably installed in the third valve core cavity 611; the third valve core 64 is connectable to the air inlet 3; the third rotating shaft 65 is sleeved on the third valve cover 63; The front end of the third rotating shaft 65 is covered with a third limit plate 66 and a third spring 67, and is rotatable and slidably connected to the valve core in the front and rear directions relative to the valve core; the third solenoid valve assembly 69 is installed in the ventilation chamber 62, for opening or closing the connection between the ventilation chamber 62 and the third valve core 64; the rear end of the third push rod 68 is connected to the front end of the third rotating shaft 65, and the front end of the third push rod 68 can slide through the third valve core 64, and the front end of the valve core chamber is connected to the third solenoid valve assembly 69, so as to be used for pressing to trigger the third solenoid valve assembly 69 to open the connection between the ventilation chamber 62 and the third valve core 64; the air outlet pipe 610 is connected to the ventilation chamber 62. The third single-outlet valve 6 is essentially the same as the first single-outlet valve 4, differing in that the third valve body 61 has been modified to include a third valve core chamber 611 and a vent chamber 62. A third solenoid valve assembly 69 is disposed within the vent chamber 62, and a third push rod 68 is used to press and trigger the third solenoid valve assembly 69 to open the connection between the vent chamber 62 and the third valve core 64. Similar to the first single-outlet valve, the third limit plate 66 has a limit clamping portion, the third valve cover 63 has a limit slot and a rotation adjustment slot, the front end of the third rotating shaft 65 has a locking head, and the rear end of the third valve core 64 has a locking slot.When the air source needs to be opened, the third shaft 65 is pressed to move in the direction of the third valve core 64, and the third limit plate 66 moves synchronously with the third shaft 65. The limit card part breaks away from the restriction of the limit groove and enters the rotation adjustment groove. The card head slides in the direction of the third valve core 64 and is embedded in the card slot. The third spring 67 is compressed. At the same time, after the card head enters the card slot, the top pressure pushes the third push rod 68 to slide along the front end direction of the third valve body 61. The front end of the third push rod 68 can slide through the sleeve slot and the inner cavity of the third valve core 64 in turn, and is connected with the third solenoid valve group When the third solenoid valve assembly 69 is in contact with each other, the third solenoid valve assembly 69 is triggered to open the connection between the third valve core 64 and the ventilation chamber 62. At this time, according to the needs, the third rotating shaft 65 is rotated according to the designed rotation angle, and the limit card part is rotated according to the set rotation angle in the rotation adjustment groove. The third rotating shaft 65 rotates to the set rotation angle, driving the third valve core 64 to rotate, and the connection to the air outlet pipe 610 can be opened. In this way, the gas can pass through the air inlet 3, the ventilation chamber 62, and the inner cavity of the third valve core 64 in sequence, and finally flow out from the air outlet pipe 610, realizing the control of a single air outlet. When the air source needs to be shut off, the third rotating shaft 65 first rotates back to its initial position, and the third valve core 64 rotates synchronously with the third rotating shaft 65. The connection between the third valve core 64 and the air outlet pipe 610 is closed, and the position of the limit clamp portion corresponds to the position of the limit groove. Under the action of the third spring 67, the limit clamp portion returns to the limit groove, and the card head moves in the sleeve slot along the direction of the third valve cover 63, and the third rotating shaft 65 is reset. At this time, the third push rod 68 lacks the pressing force of the third rotating shaft 65, and the third solenoid valve assembly 69 closes the connection between the ventilation chamber 62 and the third valve core 64. The arrangement of the third solenoid valve assembly 69 and the rotation and closure of the third valve core 64 achieve the effect of doubly closing the air outlet pipe 610. The third single air outlet valve 6 designed in this way has a simple structure, is easy to operate, and has a single air outlet for air outlet, which is convenient for users to use and has a better safety effect.

[0053] Preferably, the outlet pipe 610 includes a pipe joint 6101 connected to the vent cavity 62 and a long aluminum tube nozzle 6102 connected to the pipe joint 6101. The outlet pipe 610 is formed by arranging the pipe joint 6101 and the long aluminum tube nozzle 6102. The sufficiently long aluminum tube nozzle 6102 can further improve the convenience of use.

[0054] In order to automatically operate the third single air outlet valve 6, a micro switch 52 is installed on the third valve cover 63. The micro switch 52 can drive the third rotating shaft 65 to automatically move and rotate, thereby improving the convenience of the structure. The single air outlet is more convenient for users to use.

[0055] For the simple valve with two air outlets, in this embodiment, Figure 7As shown, the dual-outlet simple valve is a fourth dual-outlet valve 7; the valve body and valve cover are respectively a fourth valve body 71 and a fourth valve cover 72; the fourth dual-outlet valve 7 also includes a fourth valve core 73, a fourth rotating shaft 74, a fourth limiting plate 75, a fourth spring 76, a fourth left air outlet portion 77 and a fourth right air outlet portion 78; the fourth valve body 71 has a fourth air inlet cavity connected to the air inlet 3, and a fourth valve core cavity 711 connected to the fourth air inlet cavity; the fourth valve core 73 is rotatably mounted in the fourth valve core cavity 711; the fourth The rotating shaft 74 is sleeved on the fourth valve cover 72; the front end of the fourth rotating shaft 74 is sleeved with a fourth limit plate 75 and a fourth spring 76, and is rotatable and slidably connected to the fourth valve core 73 in the front and rear directions relative to the fourth valve core 73; the fourth left air outlet portion 77 and the fourth right air outlet portion 78 are connected to the side of the fourth valve body 71 corresponding to the positions of the fourth valve core cavity 711, and are respectively communicated with the fourth valve core cavity 711; the fourth valve core 73 can be communicated with the fourth left air outlet portion 77 and the fourth right air outlet portion 78, respectively. The fourth double air outlet valve 7 is formed by providing the fourth valve body 71, the fourth valve cover 72, the fourth valve core 73, the fourth rotating shaft 74, the fourth limiting plate 75, the fourth spring 76, the fourth left air outlet portion 77 and the fourth right air outlet portion 78. The fourth double air outlet valve 7 is basically the same as the first single air outlet valve 4. The difference is that the gas flow direction is improved. When in use, the fourth rotating shaft 74 is adjusted by moving and rotating. When the fourth valve core 73 is connected to the fourth left air outlet portion 77 or the fourth right air outlet portion 78, the gas first enters from the air inlet 3, passes through the fourth air inlet cavity and the inner cavity of the fourth valve core 73, and then flows out from the fourth left air outlet portion 77 or the fourth right air outlet portion 78. The double air outlet control can improve the flexibility of use, better meet the needs of various application scenarios, and facilitate user use.

[0056] On the basis of the fourth dual-outlet valve 7, another embodiment is as follows: Figures 7 and 8As shown, the fourth dual-outlet valve 7 further includes a fifth push rod 81 and a fifth solenoid valve assembly 82. The fifth push rod 81 and the fifth solenoid valve assembly 82 are added to the fourth dual-outlet valve 7 to form the fifth dual-outlet valve 8. The fifth solenoid valve assembly 82 is installed in the fourth air inlet cavity and is used to open or close the connection between the fourth air inlet cavity and the fourth valve core 73. The rear end of the fifth push rod 81 is connected to the front end of the fourth rotating shaft 74. The front end of the fifth push rod 81 can slide through the fourth valve core 73 and the front end of the fourth valve core cavity 711 to connect with the fifth solenoid valve assembly 82, so as to press and trigger the fifth solenoid valve assembly 82 to open the connection between the fourth air inlet cavity and the fourth valve core 73. A fifth dual-outlet valve 8 is formed by combining a fourth valve body 71, a fourth valve cover 72, a fourth valve core 73, a fourth rotating shaft 74, a fourth limiting plate 75, a fourth spring 76, a fourth left outlet portion 77, a fourth right outlet portion 78, a fifth push rod 81, and a fifth solenoid valve assembly 82. The fifth dual-outlet valve 8 is substantially similar to the combination of the fourth dual-outlet valve 7 and the third single-outlet valve 6. When the gas source is opened, the fourth shaft 74 is adjusted by moving and rotating, and the fifth push rod 81 moves with the fourth shaft 74, and the top pressure triggers the fifth solenoid valve assembly 82 to open the connection between the fourth air inlet chamber and the fourth valve core 73. When the fourth valve core 73 is connected to the fourth left air outlet portion 77 or the fourth right air outlet portion 78, the gas first enters from the air inlet 3, passes through the fourth air inlet chamber and the inner cavity of the fourth valve core 73, and then flows out from the fourth left air outlet portion 77 or the fourth right air outlet portion 78. The dual air outlet control, the opening and closing setting of the fifth solenoid valve assembly 82, and the rotation opening or closing of the fourth valve core 73 achieve the effect of doubly closing the fourth left air outlet portion 77 or the fourth right air outlet portion 78, which can improve the flexibility of use, better meet the needs of various application scenarios, facilitate user use, and have better safety effects.

The right valve body 912 is connected to the installation cavity 9121; the sixth push rod 99 is slidably connected to the sixth rotating shaft 94 and is connected to the flameout temperature control package 98, and is used to press the flameout temperature control package 98 to open the connection between the air guide cavity 9122 and the installation cavity 9121; when the rotating shaft moves and rotates to be stuck in the left card slot 921, the sixth valve core 93 is connected to the sixth left air outlet portion 96; when the rotating shaft moves and rotates to be stuck in the right card slot 922, the sixth valve core 93 is connected to the air guide cavity 9122.

[0058] Specifically, the flameout temperature control package 98 includes a temperature sensing probe and an elastic seal; the elastic seal is installed in the installation cavity 9121 and connected to the sixth push rod 99, and is used to open or close the connection between the air guide cavity 9122 and the installation cavity 9121; the temperature sensing probe is connected to the elastic seal and extends outside the front end of the left valve body 911.

By designing the main gear plate and the sub-gear plate to form an axis linkage structure 95, when the sixth rotating shaft 94 rotates, the main gear plate and the sub-gear plate rotate synchronously with the sixth rotating shaft 94, thereby driving the sixth valve core 93 to rotate, which can effectively realize the rotation of the sixth valve core 93, so that the sixth left air outlet 96 and the sixth right air outlet 97 can be connected to the sixth valve core 93 respectively, realizing stable gas discharge from the sixth left air outlet 96 and the sixth right air outlet 97.

[0059] In order to better ensure that the sixth rotating shaft 94 is stably inserted into the left slot 921 or the right slot 922 , the sixth rotating shaft 94 is provided with a shaft clamping portion that can be inserted into the left slot 921 and the right slot 922 and is located outside the integrated valve cover 92 .

[0060] In another embodiment, the sixth dual-outlet valve 9 further includes a seventh solenoid valve assembly 101, a slide rod 102, a lever pressing piece 103 and a push piece 104 electrically connected to the flameout temperature control package 98; the seventh dual-outlet valve 10 is formed by setting a sixth valve core 93, a sixth rotating shaft 94, a shaft linkage structure 95, a sixth left air outlet portion 96, a sixth right air outlet portion 97, a flameout temperature control package 98, a sixth push rod 99, a seventh solenoid valve assembly 101, a slide rod 102, a lever pressing piece 103 and a push piece 104; the seventh solenoid valve assembly 101 is installed in the sixth air inlet cavity 9111, and is used to open or close the communication between the sixth air inlet cavity 9111 and the sixth valve core 93, and the lever pressing piece 103 is used to open or close the communication between the sixth air inlet cavity 9111 and the sixth valve core 93. One end of the lever 104 is sleeved on the sixth rotating shaft 94 and connected to the rear end of the right valve body 912, and the other end extends to the rear end of the left valve body 911; the rear end of the sliding rod 102 is connected to the lever pressing plate 103, and the front end of the sliding rod 102 can slide through the sixth valve core 93, the front end of the sixth valve core chamber 9112 and the seventh solenoid valve assembly 101, which is used to press the seventh solenoid valve assembly 101 to open the connection between the sixth air intake chamber 9111 and the sixth valve core chamber 9112; the pushing plate 104 is sleeved on the rotating shaft and is located behind the lever pressing plate 103, and moves with the sixth rotating shaft 94 toward the front of the right valve body 912 to push the lever pressing plate 103. The seventh dual air outlet valve 10 is an improvement on the basis of the sixth dual air outlet valve 9, and the principles of the two are basically the same. For the seventh dual air outlet valve 10, when it is necessary to open the sixth left air outlet part 96, the sixth rotating shaft 94 is adjusted to move and rotate, and the shaft clamping part is clamped into the left clamping groove 921. The main gear plate and the sub-gear plate rotate synchronously with the sixth rotating shaft 94, thereby driving the sixth valve core 93 to rotate, so that the sixth valve core 93 is connected to the left air outlet part. At this time, when the sixth rotating shaft 94 rotates and moves relative to the front of the right valve body 912, the sixth push rod 99 is pushed by the movement of the sixth rotating shaft 94 and moves synchronously to the front of the right valve body 912, pushing the flameout temperature control package 98, and the top pressure triggers the flameout temperature control package 98 to open. The air guide cavity 9122 is connected with the installation cavity 9121, and the flameout temperature control package 98 is energized and working; and in the process of the sixth rotating shaft 94 moving toward the front of the right valve body 912, the pushing plate 104 pushes the lever pressing plate 103, and the other end of the lever pressing plate 103 is pushed, so that the sliding rod 102 passes through the sixth valve core 93 and the front end of the valve core cavity, and presses the seventh solenoid valve assembly 101 to open the connection between the air intake cavity and the sixth valve core cavity 9112, thereby realizing the connection between the sixth air intake cavity 9111 and the sixth valve core 93, and the seventh solenoid valve assembly 101 is energized and working; then the gas passes through the air inlet, the sixth air intake cavity 9111, and the inner cavity of the sixth valve core 93 in turn, and finally flows out from the sixth left air outlet.

[0061] When the sixth right air outlet 97 needs to be opened, the sixth shaft 94 is adjusted to move and rotate, the shaft clamping part is clamped into the right clamping groove 922, the main gear plate and the sub-gear plate rotate synchronously with the sixth shaft 94, thereby driving the sixth valve core 93 to rotate, so that the sixth valve core 93 is connected to the air guide cavity 9122. At this time, when the sixth shaft 94 rotates and moves relative to the front of the right valve body 912, the sixth push rod 99 is pushed by the movement of the sixth shaft 94 and moves synchronously to the front of the right valve body 912, pushing the flameout temperature control package 98. The top pressure triggers the flameout temperature control package 98 to open the communication between the air guide cavity 9122 and the installation cavity 9121, and the flameout temperature control package 98 is energized to work. At the same time, the sixth valve core 93, the air guide cavity 9122, the installation cavity 9121, and the sixth right air outlet 97 are connected. The four are connected, opening the sixth right air outlet 97; and in the process of the sixth rotating shaft 94 moving toward the front of the right valve body 912, the pushing plate 104 pushes the lever pressing plate 103, and the other end of the lever pressing plate 103 is pushed, so that the sliding rod 102 passes through the sixth valve core 93 and the front end of the sixth valve core cavity 9112, and presses the seventh solenoid valve assembly 101 to open the communication between the sixth air inlet cavity 9111 and the sixth valve core cavity 9112, thereby realizing the communication between the sixth air inlet cavity 9111 and the sixth valve core 93, and the seventh solenoid valve assembly 101 is energized and works; then the gas passes through the air inlet, the sixth air inlet cavity 9111, the inner cavity of the sixth valve core 93, the air guide cavity 9122, the installation cavity 9121 in sequence, and finally flows out from the sixth right air outlet 97.

[0062] When a temperature abnormality occurs, a temperature sensing probe is used to sense the external temperature. When the sensed temperature is higher than a preset value, the temperature sensing probe can push the elastic seal due to thermal expansion and contraction, and the elastic seal pushes the sixth push rod 99 and the sixth rotating shaft 94 in the opposite direction to move, thereby closing the connection between the gas guide cavity 9122 and the installation cavity 9121, quickly closing the gas flow, and feeding back a closing signal to the seventh solenoid valve assembly 101. At this time, the seventh solenoid valve assembly 101 also works, and the top pressure slide rod 102 is reset, quickly closing the connection between the sixth air inlet cavity 9111 and the sixth valve core 93, preventing the gas from flowing out from the sixth left air outlet 96 and the sixth right air outlet 97, thereby improving the safety of the structure, better ensuring that the gas supply can be cut off in time in the event of temperature abnormality, and better ensuring the continuity, stability and safety of the gas supply, thereby achieving the effect of double safety protection.

[0063] In summary, the embodiment of the present invention provides a combination assembly of a gas pipe and a gas switching valve, wherein the combination assembly of the gas pipe and the gas switching valve is provided by combining a gas pipe 1, a single-outlet simple valve and a double-outlet simple valve, rationally designs the distance from the central axis of the air inlet 3 to the rear end face of the valve cover, and the distance between the central axis of the valve body and the central axis of the gas pipe 1, rationally designs the size range between the gas pipe 1 and the valve body, and the size range between the air inlet 3 and the valve cover, so as to better optimize the spatial structure of the structure in the horizontal and vertical directions, make the overall structure more compact, and adopt a miniaturized design to avoid the structure from occupying too much space, and can easily adapt to various narrow installations. The installation environment improves the utilization rate of the structure's space, and can better realize the close arrangement of the single-outlet simple valve and the double-outlet simple valve on the same panel without the need for additional structural auxiliary fixation, thereby achieving the simplicity of the structure. It not only simplifies the installation process and facilitates installation and maintenance, but also improves the overall aesthetics and neatness of the equipment, so that the combined assembly of the gas pipe and the gas switch valve can be widely used in various gas equipment, such as gas stoves, gas water heaters, etc., with good versatility and practicality; at the same time, it also fully considers the manufacturing cost factor, the reduction in material usage, and the simplification of the production process, all of which effectively reduce the manufacturing cost and are more suitable for promotion in the market.
