The suction and blowing diverter (1) suction and blowing port expands forward and shrinks backward to highlight the convex and concave, and increases the beauty; several shapes are connected to more shaped inner chambers, and several shapes of suction and blowing ports are connected. The "A expanded suction and blowing port 208" is arbitrarily transformed, and the "A expanded suction and blowing port 207" is arbitrarily transformed, and the "A straight suction and blowing port 202" is arbitrarily transformed and connected for ventilation; the connecting parts are arbitrarily transformed, the pressure-gathering hole, and the suction during welding are preferably suitable for accurate smoke removal in the strong pressure state layer; Figure 6 pass Figure 1 Multiple shape-changing connectors, deformation-changing connections, straight-contraction-expansion three-shape connection suction and blowing port double-layer inner gap suction and blowing diverter 213.

[0090] Figure 7 As shown, in Figure 1 On the basis of the shape-changing suction and blowing diverter 1, in the connection of the multi-shape changing inner chamber, a straight-shrinking three-shape connection suction and blowing port double-layer inner gap suction and blowing diverter 215 is another one of them, which is connected with the tin soldering gun as a whole, and is deformed with the "A-shrinking suction and blowing port 207, and can be arbitrarily replaced with "A-expanded suction and blowing port 208", arbitrarily transformed into "A-shrinking suction and blowing port 207", and arbitrarily transformed into "A-straight suction and blowing port 202"; the straight-shrinking three-shape suction and blowing diverter 215 is composed of a straight inner chamber 2, a shrinking inner chamber 7, and a "A-shrinking suction and blowing port 205" is connected in several shapes, and the "A-shrinking suction and blowing port 207" is connected without a pressure-gathering piece; during welding, the "A-shrinking suction and blowing port 207" is connected with a reasonable inner gap; the "A-shrinking" suction and blowing port 207 is reduced to a certain size of the welding gun body, and through the suction and blowing diverter 1, The front suction and blowing port is reduced, and the inner chamber connected to the rear end of the front suction and blowing port is reduced, and the straight inner chamber 2 that is slightly larger than the welding gun body is connected to the deformed shape, which highlights the beauty; it can also change into a variety of different aesthetic tin welding guns and all low-temperature welding guns according to the deformation shape; the straight shrinking three-shaped connection suction and blowing port double-layer inner gap suction and blowing diverter 215 is connected to the tin welding gun, which increases the beauty and practical adaptability; the suction and blowing diverter 1 bypasses the heating element during the suction through the double-layer inner gap of the suction and blowing port, and the heating element is provided with insulation measures, which eliminates the low-temperature welding gun, and the single-layer suction port suction process cools the heating element; all low-temperature welding guns can only inhale and remove smoke, and the welding process inhales through the suction and blowing port, and the smoke enters the hose and is discharged for smoke removal; the low-temperature welding gun cannot produce combustion conditions due to the low temperature; Figure 7 pass Figure 1 Multiple shape-changing connecting parts, deformation and transformation, straight-contracting and shrinking three-shape connecting suction and blowing mouth double-layer inner gap suction and blowing diverter 215.

[0091] Figure 8 As shown, in Figure 1 On the basis, the suction and blowing diverter 1 is transformed according to the shape deformation, the threaded connection is changed, and the straight-contracted straight-contracted four-shaped connection suction and blowing diverter 212 is connected. According to the adaptability of each welding gun, it can be optionally connected with a variety of adapted welding guns; Figure 8 pass Figure 1 Multiple shape-changing connectors, deformation and transformation, threaded connection, straight-contraction, straight-contraction four-shape connection suction and blowing diverter 212.

[0092] A plurality of welding gun suction and blowing diverters 1 with various shapes and a plurality of connection methods, wherein the suction and blowing ports are integrated with the pressure-gathering member and connected with the respective suction and blowing ports by threads.

[0093] Various types of welding guns and various types of suction and blowing diverters 1, as long as they are ventilated through the inner cavity of the welding gun, are all "E non-prominent suction and blowing air ducts". Regardless of how the connecting parts are connected, they are all integrated connections.

[0094] The connection parts between various types of welding guns and the suction and blowing diverter 1, and the connection parts between the suction and blowing diverter 1 and each connecting part, are plug-in, snap-in, threaded, fused together, and include any connection method. As long as the connection method can achieve better adaptability, any connection method can be selected without limitation.

[0095] Ventilation status of suction and blowing diverter 1:

[0096] Multiple shaped suction and blowing air ducts are connected to the inner chamber expansion 8 for ventilation. The inner chamber expansion 8 connected by the suction and blowing diverter 1 reduces the lateral oblique impact force and is guided to the suction and blowing diverter 1 under the action of the impact force. The air pressure in the inner chamber is unevenly distributed. The inner chamber is connected to a contracted inner chamber 7, which is gathered and pressurized. Multiple shaped pressure-gathering parts are gathered and pressurized. Multiple porous pressure-gathering holes are gathered and pressurized. Among the multiple concentration and pressurization, one of the flat-shaped pressure-gathering parts 4 is adjusted and enhanced, and the pressure-gathering hole 5 is adjusted and enhanced. Its shape is fixed to the suction and blowing state to form a strong pressure state layer.

[0097] Another ventilation condition of suction and blowing diverter 1:

[0098] The suction and blowing diverter 1 is connected to the suction and blowing air duct with a reduced inner chamber connection, a straight inner chamber connection, a variety of multi-shaped inner chamber connections, and an arbitrarily changed connection position connection. When the suction and blowing diverter 1 produces ventilation resistance and the pressure is unevenly distributed, the vent holes are reduced by the pressure gathering piece to increase the pressure. By keeping the pressure balanced through the vent holes of the pressure gathering piece evenly distributed, a strong pressure state layer is formed.

[0099] Take the example of inhalation and smoke removal:

[0100] During the welding process, the fume is compressed around the welding melting point by the strong pressure state layer. The welding fume is compressed by the inhalation strong pressure state layer to prevent the fume from leaking out. During the inhalation process, the strong pressure state layer compresses the fume around the welding melting point and mixes with oxygen to burn and remove the fume at the high temperature of the welding melting point.

[0101] Take blowing smoke removal as an example:

[0102] During welding, the front suction port blows air from the inside to the outside, and the high pressure layer compresses the smoke around the welding melting point. Under the compression of the high pressure layer, the smoke mixes with oxygen and burns to remove smoke in the high temperature of the welding melting point.

[0103] Suction smoke removal and blowing smoke removal each have their own strengths. Suction smoke removal is suitable for "B welding melting point close distance" suction. The suction and blowing diverter 1 suction and blowing port, during the welding process, the suction and blowing port is very close to the welding melting point. The advantages are that suction does not require too much suction force, and the suction power is small. The smoke is compressed around the welding melting point through a strong pressure state layer and mixed with oxygen to burn and remove smoke at high temperature; because the suction port is very close to the welding melting point, field work is not affected by wind direction, and high temperature is used around the welding melting point, and strong pressure state layer is used to compress and increase oxygen, and smoke can be removed again after combustion and smoke removal.

[0104] Blowing to remove smoke, e.g. Figure 2 The electric welding gun connected with the expansion and contraction expansion four-shaped suction and blowing diverter 214 is suitable for welding in a very narrow and small space under specific circumstances. When the welding gun head is limited and cannot be welded, an electric welding gun is used for welding. It can remove smoke well and is convenient and flexible to use. It is especially suitable for continuous welding of thin iron plates and continuous arc welding. Because the wind force of the blowing smoke removal is strong, the periphery of the welding melting point is rapidly cooled, making it difficult for the welding thin iron plate to be penetrated. The disadvantage is that the welding process cannot remove smoke again after the high-temperature mixed oxygen smoke removal under a strong pressure state. Generally, close-range suction smoke removal is used as the main method, and blowing smoke removal is used under specific circumstances.

[0105] Now, a number of shaped and concentrated pressure parts and a number of shaped and concentrated pressure holes are added to explain the distribution of the layers of strong pressure states adjusted according to the characteristics of various welding guns and the deformation:

[0106] Take the flat adjustment pressure piece as an example:

[0107] Among the multiple shape-changing pressure-gathering pieces, one of the flat adjustment and reinforcement pressure-gathering pieces 4 is provided with multiple holes. The suction and blowing diverter 1 is deformed according to the characteristics of various welding guns in many embodiments, including triangular △ hole-shaped air holes, multiple triangular △ hole-shaped air holes, one angle in the same direction to the center, two angles in the same direction to the outer circumference, and multiple triangular △ air holes are evenly arranged from the inner edge of the outer periphery. Because the outer periphery is also two-angled in the outer circumference, air is sucked and blown during welding, forming a large flow rate in the outer circumference, forming a natural outward expansion, which is an outward expanding strong pressure state layer.

[0108] The flat-adjustable enhanced pressure-gathering piece 4 has multiple triangular △-hole pores, one corner facing the outer circumference, and two corners facing the center. Multiple triangular △ holes are evenly arranged from the inner edge of the outer circumference. Because the two corners face the center, the natural wind flow toward the center is large, forming a natural gathering toward the center, which is a gathering and shrinking strong pressure state layer.

[0109] A plurality of circular holes are arranged on the outer periphery of the flat adjustment pressure gathering piece 4, and the circular holes on the outer periphery are arranged to form a straight strong pressure state layer by suction and blowing during welding. The straight strong pressure state layer is the space inside the front suction and blowing port, which is the same size as the space inside the welding melting point and is the distribution layer of the straight strong pressure state layer.

[0110] Take the concave reinforced compression piece as an example:

[0111] The concave adjustment enhancement pressure-gathering piece 15 has a plurality of holes on the inner edge of the outer periphery, and a straight hole is one of them. Taking the straight hole as an example: a plurality of straight holes have one end toward the center and the other end toward the outer periphery, and the straight holes are evenly arranged from the inner edge of the outer periphery. Because the center is concave, the outer periphery naturally forms an inclination toward the center, and a plurality of straight holes are evenly arranged on the inner edge of the outer periphery. When welding, inhaling or blowing air also naturally inclines toward the center, forming a gathering toward the center, which is a reduced-shaped high-pressure state layer.

[0112] The deeper the concave shape is, the greater the gathering force toward the center is, and the smaller the high pressure state layer is; the shallower the concave shape is, the smaller the gathering force toward the center is, and the larger the high pressure state layer is; if the concave shape is evenly distributed at multiple levels of depth, there will be high pressure state layers of multiple angles and sizes.

[0113] Take the convex adjustment reinforcement pressure piece as an example:

[0114] The concave reinforcing pressure-gathering piece 15 is connected by a concave reverse shape, and the concave shape becomes convex. A straight hole is one of them. Taking the straight hole as an example, multiple straight holes have one end toward the center and the other end toward the outer circumference. Multiple straight holes are evenly arranged on the inner edge of the outer circumference. Because the center is conically convex upward, a natural inclination is formed toward the outer circumference. Multiple straight holes evenly arranged on the inner edge of the outer circumference naturally tilt outward during suction or blowing during welding, forming an outward expanding strong pressure state layer.

[0115] The higher the convexity, the greater the outward expansion angle of the high pressure state layer. The convexity is evenly distributed at multiple levels, and there are high pressure state layers with multiple angles and sizes distributed in layers.

[0116] Multiple adjustment pressure-gathering parts and multiple adjustment pressure-gathering holes can adjust the distribution of multiple internal spaces in the high-pressure state layer. The melting point temperatures of various welding guns vary greatly. The higher the melting point, the larger the space in the high-pressure state layer with a high temperature, and the smaller the melting point, the smaller the space in the high-pressure state layer. Multiple and multi-shaped welding guns are required to have multiple spaces in the high-pressure state layer of different sizes. During the welding process, air is sucked or blown to adapt the melting point temperature to the size of the space in the high-pressure state layer, the size of the wind pressure in the high-pressure state layer is adapted, and the mixed oxygen is adapted. By comparing and balancing several aspects, accurate smoke removal can be achieved.

[0117] Because the best smoke removal is that the high pressure state layer compresses the smoke around the melting point of the welding, and the smoke does not leak out; the high pressure state layer can also provide enough space inside the high pressure state layer to mix with oxygen. The high pressure state layer compresses the smoke around the melting point of the smoke, and the high temperature mixed oxygen burns to remove the smoke;

[0118] Tin soldering guns and other low-temperature welding guns cannot remove smoke through the suction and blowing process because the melting point of the solder is too low and there is a lack of combustion conditions. The smoke can only be removed through the suction and blowing diverter and the outlet hose.

[0119] A variety of multi-shaped welding guns can adjust the smoke removal adaptability of each welding gun through a plurality of adjustment parts. The suction and blowing diverter 1 can be connected to the inner chamber by any combination of connecting parts, whether it is connected from one-shaped inner chamber connection, several-shaped combined inner chamber connection, several-shaped inner chamber interchangeable position combination connection, any-shaped inner chamber combination connection, several-shaped inner chamber re-shape reorganization connection, multiple-shaped inner chambers must be separated by non-same-shaped combination connection, any-shaped special deformation inner chamber combination connection, there is no fixed shape inner chamber connection, all can be arbitrarily changed in shape connection, unlimited shape connection, and any shape can be arbitrarily changed to connect ventilation.

[0120] Arbitrary transformation of "A expanded suction and blowing port 208", "A contracted suction and blowing port 207", "A straight suction and blowing port 202", and connection with polymorphic inner chambers; arbitrary transformation of polymorphic suction and blowing ports, and connection with inner chambers for ventilation".

[0121] There are various suction and blowing air ducts with different shapes, all of which have no fixed shape connection. Various suction and blowing air ducts with different shapes, including the suction and blowing air ducts in the inner cavity of the welding gun, are connected with their own adaptive inner chambers; you can arbitrarily select the suction and blowing ports adapted to each welding gun to connect; you can arbitrarily select the adaptive, D, E, suction and blowing air ducts to connect for ventilation.

[0122] Any adaptable selection of various welding guns can change the ventilation angles of multiple high-pressure state layers by adjusting the pressure-gathering parts, adjust the pressure-gathering holes to change multiple hole shapes, change the ventilation angles, multiple adjustment parts, and adjustment holes. According to the needs of each welding gun, you can arbitrarily choose to adjust the pressure-gathering parts and adjust the pressure-gathering holes. You can arbitrarily adjust the size of the space in the high-pressure state layer and the size of the welding melting point, adapt to the reasonable comparison of mixed oxygen, and the reasonable pressure size of the high-pressure state layer. The adaptability conditions between each are adjusted balanced, and various types of welding guns can accurately remove smoke.

[0123] There are also multiple special-shaped holes, arranged at multiple angles and multiple positions, which also produce different angle distribution strong pressure layers; the multi-level strong pressure state layer distribution layer has a variety of adjustment methods to ensure the strong pressure state layer, accurately covering the welding fume and preventing it from leaking out; the suction and blowing diverter 1 is based on the appearance characteristics of the welding gun, and the suction and blowing diverter 1 has all-round connectors with beautiful appearance, practical convenience and perfection, and changes with the shape deformation, and is connected with various welding gun characteristics and adaptability and beauty. The suction and blowing diverter 1 is deformed according to the overall beauty of each welding gun, deformed for practicality and convenience, and deformed for precise smoke removal.

[0124] The suction and blowing diverter 1 is designed to achieve better precision adaptability of each connecting part, and any connecting part can be arbitrarily deformed and connected; each connecting part can be arbitrarily deformed and connected with the shape of the welding gun, and the all-round connecting part can be deformed and changed with the welding gun shape, and the position of the connecting part can be arbitrarily changed, and the connecting part can be arbitrarily deformed and connected. Each connecting part can be arbitrarily extended, shortened, enlarged or reduced, and any special deformation of characteristics is not restricted to produce a shape with a different proportion, such as the deformation with the shape, Figure 2 : 8, 7, the proportions are different, Figure 6: 208, 7, the proportions are different, Figure 7 :207, Figure 8 : 207 ratio difference, etc.: suction and blowing diverter 1 adapts to the requirements of various characteristics of welding guns by increasing the contrast ratio. In order to achieve the adaptability of various welding guns, it can be arbitrarily deformed and transformed to connect; amorphous and non-positioned arbitrary splicing combination connection, without limiting the deformation and transformation connection of any connecting parts, each connecting part has its own shape, which can be optimized with the shape deformation of various types of welding gun characteristics; various characteristics of welding guns select each adaptive high pressure state layer, inhale or blow air during the welding process, and compress the smoke through the high pressure state layer around the welding melting point to mix with oxygen and burn at high temperature to remove smoke.

[0125] Of course, the multi-shape transformable suction and blowing mouth can be an extended single-layer suction and blowing mouth, or a non-extended single-layer suction and blowing mouth. Multiple-shape suction and blowing mouth can be transformed into the double-layer inner gap suction and blowing mouth; single, double, and any welding gun characteristics can be selected; the changing and transforming suction and blowing mouth can be transformed into the respective single, double, extended, shortened, and multi-shape transformable suction and blowing mouth according to the requirements of each welding gun, and the transformation adapts to the characteristics of each welding gun to meet the requirements.

[0126] Of course, the suction and blowing diverter 1 with multiple shapes can be connected to various welding guns in one piece, and can also be changed, disassembled, installed and connected; Figure 2-Figure 7 As shown, the suction and blowing diverter 1 is integrally connected to the welding gun, and is connected to the suction and blowing air duct E without protruding it; the suction and blowing air duct E is not prominent, and can be transformed to connect to the suction and blowing air duct D that protrudes it, and can be detachably disassembled and installed; according to the characteristic conditions of each welding gun, the two air duct connection methods D and E can be arbitrarily transformed and each welding gun connection method can be adaptively transformed to connect them. Various multi-shaped welding guns are fixedly connected through the set hole 11 and the center hole of the reinforcing pressure-gathering piece 4 is adjusted. The connection is not limited to any fixed connection method, and several fixing methods can be arbitrarily fixedly connected.

[0127] All-round connectors, no restrictions on any connectors can be arbitrarily deformed with the welding gun type; through characteristic change connection, countless blowing diverter 1 characteristics can be changed to adapt to various welding gun requirements and can be selected at will.

[0128] The front suction and blowing port of the suction and blowing diverter 1 and the inner chamber can be changed arbitrarily, and the inner chamber can be connected in the positive and negative positions of expansion, contraction, straightness, and multiple shapes. Among them, each shape of the inner chamber can be reorganized to have multiple different suction and blowing diverters 1; multiple shapes are connected to the inner chamber, and each inner chamber can be reorganized to have more different suction and blowing diverters 1; multiple shapes of inner chambers can be reorganized into multiple shapes of suction and blowing diverters 1; multiple shapes of inner chambers can be reorganized into the same shape inner chamber for indoor connection, two same shape inner chambers can be reorganized into indoor connection for ventilation, multiple same shape inner chambers can be reorganized into indoor connection, and reorganized inner chamber connection can only be changed to show the beautiful features of concave and convex, show the convenience of use, and change the countless shapes of suction and blowing diverter 1. According to various welding gun requirements, it can be arbitrarily adapted and selected.

[0129] No matter how the suction and blowing diverter 1 is deformed and connected, it can be deformed through the pressure-gathering parts, concave, convex, flat, and multiple transposition connections to change the ventilation angles of the strong pressure state layer in multiple shapes; through multiple hole changes, the ventilation angles of the strong pressure state layer can be changed; the suction and blowing diverter 1, no matter how it changes its shape, can have multiple ventilation angles and strong pressure state layers to adapt to multiple shape changes, and each of the multiple shapes of the suction and blowing diverter 1 can be changed.

[0130] The suction and blowing diverter 1 is deformed according to the characteristics of each welding gun, changing the suction and blowing diverter in the welding gun cavity, changing the straight welding gun to divert through any specific position, and not limiting the position diverter, the high-pressure fan air inlet, air outlet, suction and blowing diverter, no matter how special the deformation is, it is all to adapt to the adaptability of each welding gun.

[0131] Multiple shapes, expansion, contraction, straight, and inner chamber shapes can be connected to suction ports in a interchangeable manner; multiple front suction and blowing ports "A expanded suction and blowing port 208", "A contraction suction and blowing port 207", "A straight suction and blowing port 202" and other shapes can be connected to inner chambers in a interchangeable manner; through the multi-shape transformation of the suction and blowing port, the needs of various welding guns can be met; through close-range suction or blowing, accurate smoke removal conditions can be achieved, all-round connecting parts, ventilation is connected through the connecting parts, and the ventilation process of the suction and blowing port is completed; the "B welding melting point close distance" smoke removal position is limited, the suction and blowing diverter 1 is placed at several positions on the front part 12 of the welding gun, and is located at the center position of the suction and blowing diverter 1, or deviates from any position, no matter at any position, any connection method is fixed, and during the welding process, suction or blowing through the suction and blowing port can finally achieve the purpose of smoke removal. The connection position is within the "B welding melting point close distance" smoke removal protection range.

[0132] The key protections are as follows: "A expanded suction and blowing port 208", "A contracted suction and blowing port 207", "A straight suction and blowing port 202"; "B welding melting point close distance" suction and blowing are all key protection areas.

[0133] Arbitrary deformation, arbitrary transformation of connecting parts, arbitrary transformation of connection methods, including suction and blowing mouth, inner chamber, suction and blowing air duct, pressure gathering parts, suction and blowing diverter 1, arbitrary transformation with various welding guns and various connection methods, arbitrary shape-changing, shape-changing connecting parts, shape-changing connection methods of various positions, "through arbitrary deformation and displacement", "shape deformation", no matter what method is used, as long as the deformation of various welding guns' respective characteristics and the connection of changing adaptability conditions are achieved, all deformation and transformation connecting parts are within the protection scope.

[0134] The suction and blowing diverter 1 sucks and blows air through the high-pressure fan, and the high-pressure fan sucks and removes smoke. One end of the soft air duct is connected to the suction port, and the other end is connected to the gas port of the welding gun; for blowing and removing smoke, one end of the soft air duct is connected to the blowing port of the high-pressure fan, and the other end is connected to the gas port of the welding gun; for close-range suction and fume removal, a power of 100 watts-150 watts-250 watts is generally used, which can be greater than 250 watts or less than 100 watts, optional; the suction distance is far and the power size is floating, and the tin soldering gun uses a small and micro-power fan. According to the situation of the welding gun, a high-pressure fan with a power size can be arbitrarily selected, and the power size is not limited. Use the suction and blowing port to inhale, and you can choose to remove smoke once or twice; use the suction port or outlet of a high-pressure fan or a high-pressure appliance, and the secondary smoke removal method is not limited; the high-pressure appliance can be selected and the power size is not limited.

[0135] Various welding smoke removal technologies currently available occupy a large space and require a large power of about 7.5 kilowatts. After the smoke diffuses, it is sucked into the smoke removal equipment, which has a large power and high smoke removal cost. The equipment cost is high, and smoke removal can only be done indoors; smoke removal is not possible when working outdoors; smoke is removed by suction and blowing at a close distance through the front suction and blowing port. Because the smoke is wrapped in a layer of strong pressure at a close distance, it is not affected by external wind force. For smoke removal, a welding gun front part 12 is set, and smoke removal is done wherever welding is done, which completely solves the problem of accurate smoke removal without dead angles.

[0136] During the welding process, smoke always fills the face and chest of the human body. Various harmful gases in the smoke surround the human body, which greatly harms human health. The suction and blowing diverter 1 inhales and removes smoke through the suction and blowing port 2. The high-pressure state compresses the smoke so that it does not leak outward to remove the smoke. The harmful gases in the smoke are burned by high-temperature mixed oxygen during the suction process, and the smoke, smoke dust and flammable harmful gases disappear. Blowing removes smoke, high-pressure mixed oxygen burns to remove smoke, and the harmful gases in the smoke disappear, and the very few harmful gases are diffused to the periphery away from the human body.

[0137] Suction or blowing smoke removal is a strong pressure state layer compression welding melting point around, under the compression state also greatly compressed welding melting point shrink, welding melting point greatly reduced also forced to reduce the arc, because the welding melting point close to smoke removal, suction and blowing mouth from the welding melting point is very close, through a variety of welding gun suction and blowing steering device 1 several positions, various welding gun front 12 several positions, set a number of shapes of light shielding hood 26, set light shielding can see through the welding melting point, convenient operation of several shapes; light shielding hood 26, cover scattered arc damage to the human body, completely solve the smoke, harmful gases, arc damage to the human body.
