Description

Technical Field

[0001] The present invention relates to a heating component and a heating device, and in particular to an electromagnetic heating coil, a heating source, a heating head and a heater. Background Art

[0002] Heating and welding are common processing methods in the industrial and production fields, such as the plastic and rubber industry, transportation such as tunnel engineering, such as plastic film blowing machines, wire drawing machines or injection molding machines, etc., the pharmaceutical industry, energy and food industries, etc. Electromagnetic heating is a more popular heating method over the years. Since the ordinary heating coil heating method is usually a contact heat transfer heating method, the heat utilization rate is low, and only 30%-70% of its energy consumption is converted into working heat energy. Since there is a cooling inertia phenomenon during heating, if the heating is not timely, the heating time will be extended under the effect of heat dissipation. Electromagnetic induction heating can use non-contact electromagnetic induction heating, directly apply heat to the workpiece, eliminating the heat loss of heat transfer, so the temperature rises quickly and efficiently.

[0003] On February 17, 2014, the applicant filed an invention patent application entitled "A Handheld Electromagnetic Heater" with the Patent Office of the State Intellectual Property Office of the People's Republic of China and was granted the invention patent right with patent number 201410053724.2.

[0004] Since this patented product uses electromagnetic heating technology, the heating efficiency and heating quality are greatly improved, so it is very popular among customers. However, during the production and use process over the past few years, some new technical problems have also been discovered.

[0005] First, the electromagnetic heating coil is easy to burn out, affecting the normal progress of welding work.

[0006] Second, bipolar transistors (IGBT) are very easy to burn out. After repeated analysis, testing and research, the cause of burning out of bipolar transistors (IGBT) has not been found.

[0007] Third, the front end of the heating source is not easy to approach the hot melt sheet (equipped with a metal hot melt sheet, such as an iron net, an iron nail, etc.), and the heating efficiency cannot be further improved.

[0008] Fourth, although the handheld electromagnetic heater is equipped with a variety of heating heads with different front panels, it was found during use that the hot melt sheet was severely deformed after being nailed to the wall, and the states were different. The existing heating heads with different front panels were far from enough. Even if the number of heating heads with different front panels was doubled, it could not meet the needs of the work. Moreover, frequent replacement of heating heads would not only increase the labor intensity of the operators, but also affect the work efficiency and fail to achieve the best results.

[0009] Fifth, since there is a straight groove at the rear of the heating head and a corresponding straight groove at the front end of the cavity, it forms a plug-in and buckle-fixed structure, just like a snap-on bottle mouth and bottle cap with a snap-on head and a snap-on mouth. It is found in work that the connection strength of this plug-in and buckle-fixed structure is weak. Since the heating head is heavy, it is easy to fall off the gun body. In serious cases, the heating head will be damaged. In order to prevent the heating head from falling off, the operator has to hold the electromagnetic heater with both hands, or hold the heating head upwards, which is not very convenient to use.

[0010] Sixth, most waterproof cloths are not transparent. During the heating and welding process, it is difficult to find the correct position of the hot melt sheet, which can easily cause welding leaks, false welding, and biased welding.

[0011] Seventh, the resonant capacitor is set in the main box, and the voltage between the induction coil and the resonant capacitor can be as high as 1000 volts to 1800 volts. When working, the operating line of about 16 meters is in the humid and harsh tunnel working environment, which is extremely dangerous. Summary of the invention

[0012] The first technical problem to be solved by the present invention is to provide an electromagnetic heating coil, which can effectively dissipate heat when used in a heating source, effectively avoid burning out due to the high temperature of the electromagnetic heating coil during operation, and cause open circuit or short circuit, and also effectively reduce the magnetic saturation phenomenon, and solve the problem of burning out bipolar transistors (IGBT) due to magnetic saturation. It is beneficial to protect the bipolar transistors (IGBT) in the power supply and ensure the normal progress of welding work.

[0013] The second technical problem to be solved by the present invention is to provide a heating source, which can effectively dissipate heat in the heating head, effectively avoid burning out due to the high temperature of the electromagnetic heating coil during operation, and cause open circuit or short circuit, and also effectively reduce the magnetic saturation phenomenon, and solve the problem of burning out the bipolar transistor (IGBT) due to magnetic saturation. It is beneficial to protect the bipolar transistor (IGBT) in the power supply and ensure the normal progress of welding work.

[0014] The third technical problem to be solved by the present invention is to provide a heating head, which can effectively dissipate heat when used in a heater, effectively avoid burning out due to the high temperature of the electromagnetic heating coil during operation, and cause open circuit or short circuit, and also effectively reduce the magnetic saturation phenomenon, and solve the problem of burning out the bipolar transistor (IGBT) due to magnetic saturation. It is beneficial to protect the bipolar transistor (IGBT) in the power supply and ensure the normal progress of welding work.

[0015] The fourth technical problem to be solved by the present invention is to provide a heater which can effectively dissipate heat, effectively avoid burning out due to the high temperature of the electromagnetic heating coil during operation, and cause open circuit or short circuit, and also effectively reduce the magnetic saturation phenomenon, and solve the problem of burning out the bipolar transistor (IGBT) due to magnetic saturation.

[0180] like Figure 13 to Figure 14 As shown,

[0181] This embodiment provides an electromagnetic heating coil 1-3-1, and the electromagnetic heating coil 1-3-1 is provided with a heat dissipation gap.

[0182] Various modifications of this embodiment are described below.

[0183] like Figure 13 to Figure 14 As shown, the heat dissipation gap includes an axial heat dissipation gap between layers in the electromagnetic heating coil 1-3-1. Of course, it is also possible that the heat dissipation gap includes a radial heat dissipation gap between circles in the electromagnetic heating coil 1-3-1.

[0184] The heat dissipation gap is arranged on two opposite sides of the electromagnetic heating coil 1 - 3 - 1 .

[0185] The shape of the electromagnetic heating coil 1 - 3 - 1 gradually changes from a circular shape to an elliptical shape from the inner layer to the outer layer.

[0186] The electromagnetic heating coil 1-3-1 is fixed at both ends of the elliptical short axis by binding components 1-3-5.

[0187] The binding member 1-3-5 is a thin wire or an insulating tape.

[0188] A coil heat dissipation isolation component 1-3-2 is arranged between the heat dissipation gaps.

[0189] The coil heat dissipation isolation component 1-3-2 is in the shape of a column. Of course, the coil heat dissipation isolation component 1-3-2 may also be in the shape of a tube, a comb, or a screw support.

[0190] The cross-sectional shape of the cylindrical coil heat dissipation isolation component 1-3-2 is circular, semicircular, elliptical or semi-elliptical.

[0191] The cross-sectional shape of the tubular coil heat dissipation isolation component 1-3-2 is circular.

[0192] The comb body of the comb-tooth-shaped coil heat dissipation isolation component 1-3-2 is in a long strip shape, and the length of the comb body corresponds to the axial length of the electromagnetic heating coil 1-3-1. The comb tooth length of the comb-tooth-shaped coil heat dissipation isolation component 1-3-2 is less than or equal to the radial thickness of the electromagnetic heating coil 1-3-1.

[0193] The shape of the screw support-shaped coil heat dissipation isolation component 1-3-2 is a prismatic support body.

[0194] The prism bracket body is a prism bracket body formed by fixed connection with a screw rod.

[0195] The prism support body is a triangular prism support body, a quadrangular prism support body or a hexagonal prism support body.

[0196] The lead screw is a rod made of rigid wire (such as nylon plastic).

[0197] The coil heat dissipation isolation component 1-3-2 is made of insulating material.

[0198] The insulating material is wood or bamboo or nylon or epoxy material or bakelite or polytetrafluoroethylene.

[0199] The electromagnetic heating coil 1-3-1 is shaped by shaping glue.

[0200] The shaping glue is water-like shaping glue or paste-like shaping glue.

[0201] The water-like shaping glue is 502 glue or 508 glue or 488 glue or 108 glue or ring-speed slow concentrated glue or 101 glue or 201 glue or 301 glue or 401 glue or 260 glue.

[0202] The paste-like shaping glue is epoxy resin glue such as AB glue or all-purpose glue or heat-resistant silica gel or insulating varnish.

[0203] like Figures 13 to 16 As shown, the electromagnetic heating coil 1-3-1 is wound on a coil frame 1-3-3.

[0204] The coil skeleton 1-3-3 is made of PBT.

[0205] The coil frame 1-3-3 is made of heat-resistant materials such as polytetrafluoroethylene, nylon, epoxy material, or bakelite.

[0206] The coil skeleton 1-3-3 includes a skeleton body 1-3-3-1 and a coil baffle 1-3-3-2.

[0207] The skeleton body 1-3-3-1 is cylindrical in shape.

[0208] The coil baffle 1-3-3-2 has one plate, but it is also possible that the coil baffle 1-3-3-2 has two plates.

[0209] A coil baffle 1-3-3-2 is arranged at the rear end of the skeleton body 1-3-3-1.

[0210] One of the coil baffles 1-3-3-2 is in the shape of a circular ring.

[0211] The two opposite sides of the annular coil baffle 1-3-3-2 are respectively provided with notches 1-3-3-3.

[0212] The shape of the notch 1-3-3-3 is fan-shaped.

[0213] The two radial sides of the fan-shaped notch 1-3-3-3 are perpendicular to each other.

[0214] The bottom sides of the two fan-shaped notches 1-3-3-3 are parallel to each other.

[0215] The notch 1-3-3-3 is opposite to the heat dissipation gap of the electromagnetic heating coil 1-3-1.

[0216] The two coil baffles 1-3-3-2 are arranged at the front end and the rear end of the skeleton body 1-3-3-1.

[0217] The two coil baffles have the same shape.

[0218] There are two types of heat dissipation gap processes. One is to remove the isolation component after the electromagnetic heating coil is wound and then cured with glue, leaving a heat dissipation gap. The other process is to retain the isolation component. The process of retaining the isolation component is to set a coil heat dissipation isolation component between the heat dissipation gaps.

[0219] like Fig.13 and Figures 17 to 19 As shown,

[0220] This embodiment provides a heating source 1-3, and the heating source 1-3 includes an electromagnetic heating coil 1-3-1, and the electromagnetic heating coil 1-3-1 is the electromagnetic heating coil 1-3-1 described above.

[0221] Various modifications of this embodiment are described below.

[0222] like Fig.13 and Figures 17 to 19 As shown, the electromagnetic heating coil 1-3-1 is provided with a magnetic core 1-3-4.

[0223] The magnetic core 1-3-4 is a cylindrical pot-shaped magnetic core 1-3-4. Of course, the magnetic core 1-3-4 can also be a cylindrical magnetic core 1-3-4. It can also be that the magnetic core 1-3-4 is a pot-shaped magnetic core 1-3-4. It can also be that the magnetic core 1-3-4 is a "thumbnail" shaped magnetic core 1-3-4.

[0224] The column-shaped magnetic core 1-3-4 comprises a concentrically arranged magnetic core column 1-3-4-1, a magnetic core bottom 1-3-4-2, and a magnetic core wall 1-3-4-3, wherein the magnetic core column 1-3-4-1, the magnetic core bottom 1-3-4-2, and the magnetic core wall 1-3-4-3 form an integral part, the magnetic core column 1-3-4-1 is a fixed magnetic core column 1-3-4-1, and the height of the magnetic core column 1-3-4-1 is greater than or equal to the height of the magnetic core wall 1-3-4-3. Alternatively, the magnetic core bottom 1-3-4-2 and the magnetic core wall 1-3-4-3 form an integral part, the magnetic core column 1-3-4-1 and the magnetic core bottom 1-3-4-2 are separated, and the magnetic core column 1-3-4-1 is a movable magnetic core column 1-3-4-1.

[0225] The height of the magnetic core column 1-3-4-1 is consistent with the height of the magnetic core wall.

[0226] The difference between the height of the magnetic core column 1-3-4-1 and the height of the magnetic core wall 1-3-4-3 is 7MM to 44MM.

[0227] The difference between the height of the magnetic core column 1-3-4-1 and the height of the magnetic core wall 1-3-4-3 is 15MM, 20MM, and 25MM.

[0228] The shape of the magnetic core column 1-3-4-1 is cylindrical.

[0229] The head and / or tail of the magnetic core column 1-3-4-1 is in a plane shape, a spherical shape, or a parabolic shape.

[0230] The shape of the magnetic core bottom 1-3-4-2 is disc-shaped.

[0231] A guide hole or a ventilation hole is arranged in the center of the core bottom 1-3-4-2.

[0232] The root of the movable magnetic core column 1-3-4-1 is located in the guide hole.

[0233] The magnetic core column 1-3-4-1 is provided with an insulating elastic component 1-3-4-7.

[0234] The insulating elastic component 1-3-4-7 is made of elastic rubber material.

[0235] The elastic adhesive material is a rubber material or a silicone material.

[0236] like Fig.19 As shown, the insulating elastic component 1-3-4-7 is made of a long strip of rubber or silicone material, with two ends glued to the bottom of both sides of the back of the bottom 1-3-4-2 of the magnetic core, and the middle is firmly attached to the movable magnetic core, like a bow and arrow.

[0237] like Figure 3a As shown, the insulating elastic component 1-3-4-7 can be a small pneumatic plastic telescopic rod, which includes a sleeved cylinder, an elastomer is arranged in the cylinder, and the elastomer is a spring or an elastic air bag. The small pneumatic plastic telescopic rod is like a hollow syringe, supported on the movable magnetic core column 1-3-4-1 and the reinforcing rib 1-1-4-5 at the bottom of the shell.

[0238] The movable magnetic core column 1-3-4-1 is pressed by the workpiece during operation and is forced to move backward, and vice versa, moves forward, and is reset under the action of the insulating elastic component 1-3-4-7 at the bottom.

[0239] The shape of the magnetic core column 1-3-4-1 is cylindrical.

[0240] The shape of the magnetic core bottom 1-3-4-2 is disc-shaped.

[0241] The shape of the magnetic core wall 1-3-4-3 is cylindrical.

[0242] The magnetic core column 1-3-4-1 is provided with a ventilation hole 1-3-4-4 at the axial position.

[0243] Notches 1-3-4-5 are respectively provided on two opposite sides of the magnetic core bottom 1-3-4-2 and the magnetic core wall 1-3-4-3.

[0244] The notch 1-3-4-5 is opposite to the heat dissipation gap of the electromagnetic heating coil 1-3-1.

[0245] Viewed from the axial direction, the shape of the notches 1-3-4-5 is fan-shaped.

[0246] The two radial sides of the notch 1-3-4-5 are perpendicular to each other.

[0247] The bottom sides of the two notches 1-3-4-5 are parallel to each other.

[0248] The two opposite outer side surfaces of the magnetic core wall 1-3-4-3 are respectively provided with positioning grooves 1-3-4-6 along the axial direction.

[0249] The electromagnetic heating coil 1-3-1 is sleeved on the magnetic core column 1-3-4-1.

[0250] The coil baffle 1-3-3-2 is located at the root of the magnetic core column 1-3-4-1.

[0251] This embodiment can effectively dissipate heat, effectively avoid burning out of the electromagnetic heating coil due to high temperature during operation, and cause open circuit or short circuit, and also effectively reduce the magnetic saturation phenomenon, and solve the problem of burning out the bipolar transistor (IGBT) due to magnetic saturation. It is beneficial to protect the bipolar transistor (IGBT) in the power supply and ensure the normal progress of welding work.

[0252] like Figures 1 to 3 As shown,

[0253] This embodiment provides a heating head 1, comprising a heating source 1-3, wherein the heating source 1-3 is the heating source 1-3 described above.

[0254] Various modifications of this embodiment are described below.

[0255] like Figures 1 to 3 As shown, the heating source 1-3 is located in the shell 1-1.

[0256] like Figure 20 to Figure 21 As shown, a locking fitting component 1-1-3 is provided at the rear of the housing 1-1.

[0257] The locking fitting component 1-1-3 includes a locking neck 1-1-3-1 and a locking head 1-1-3-2.

[0258] The locking neck 1-1-3-1 is a circular ring body extending backward from the rear surface of the shell 1-1.

[0259] The locking head 1-1-3-2 is a plurality of arc-shaped flanges extending radially outward from the rear edge of the outer side surface of the locking neck 1-1-3-1.

[0260] The locking heads 1-1-3-2 are evenly distributed around the circumference of the locking neck 1-1-3-1.

[0261] The arc length of the locking head 1-1-3-2 is less than or equal to twice the arc distance between two adjacent locking heads 1-1-3-2.

[0262] The number of the locking heads 1-1-3-2 is three. Of course, the number of the locking heads 1-1-3-2 can also be two. Alternatively, the number of the locking heads 1-1-3-2 can be four.

[0263] The outer side surface of the locking head 1-1-3-2 is provided with a separate opening 1-1-3-3.

[0264] The other end 1-1-3-3 is close to the locking head 1-1-3-2.
