Description

Technical Field

[0001] This utility model relates to the field of graphite heater technology, and in particular to a spliced ​​graphite heater. Background Technology

[0002] A graphite heater is an electric heating device that uses graphite as a resistance heating element and heats up rapidly after being energized. It has the advantages of small size and high heating power. Currently used graphite heaters are mostly made of a single ring-shaped graphite plate. However, it has been found that graphite plates are inconvenient to disassemble and assemble, and the large amount of graphite plate material used results in high production costs, leading to greater limitations in their use.

[0003] Chinese Patent Publication No. CN202214454U discloses a graphite heater, including a heater body and heater feet. The heater feet are provided with mounting holes. The key feature is that the heater feet and the heater body are flexibly connected together by a pin. When the heater feet break, only the heater feet need to be replaced without affecting the use of the heater body, which can save costs. However, this patent only connects the heater feet by splicing. The graphite heater itself is still an integral structure. When a part of the graphite heater fails, the entire graphite heater still needs to be replaced, which leads to increased maintenance costs. Therefore, a spliced ​​graphite heater is proposed.

[0026] like Figure 1-5 As shown, this utility model embodiment provides a spliced ​​graphite heater, including an external component 100, a heating component 200, and a limiting component 300;

[0027] The heating assembly 200 includes a graphite base 202. Twelve housings 301 are mounted on the inner bottom wall of the graphite base 202. Two springs 302 are symmetrically mounted on the inner wall of each housing 301. A slider 304 is fixedly connected to the end of each spring 302 away from the housing 301. A support rod 305 is fixedly connected to the top of each slider 304. A connecting block 306 is fixedly connected to the top of the support rod 305. A limit block 307 is mounted on one side of the connecting block 306. A connecting rod 309 is hinged to the top of each slider 304 via a pin. A sliding plate 310 is hinged to the end of each connecting rod 309 away from the slider 304 via a pin. A slide base 308 is fixedly connected to the inner bottom wall of body 301. A slide rod 303 is installed between the two ends of the inner wall of housing 301. The slide rod 303 passes through the slide base 308 and two sliders 304 respectively. The outer side wall of the slide rod 303 is slidably connected to the two sliders 304. A slide rod 311 is installed on the top of the slide base 308. A limit plate 312 is fixedly connected to the top of the slide rod 311. The outer side wall of the slide rod 311 passes through the slide plate 310 and is slidably connected to the slide plate 310. The ends of the two connecting rods 309 away from the sliders 304 are hinged to the two sides of the slide plate 310 by pins.

[0028] In one embodiment, the external component 100 includes a heating chamber 101, the top of which is hinged to a sealing cover 102. A handle 103 is mounted on the top of the sealing cover 102. The handle 103 and the sealing cover 102 are configured to seal the device during use, reducing heat loss from the heating chamber 101 and improving the device's working efficiency.

[0029] In one embodiment, four casters 106 are installed at the bottom of the heating box 101, and a push handle 104 is installed on one side of the heating box 101. The push handle 104 and the casters 106 make it easy to move and adjust the device, reducing usage limitations.

[0030] In one embodiment, an electric base 201 is installed on the inner bottom wall of the heating box 101. The top of the electric base 201 is fixedly connected to the bottom of the graphite base 202. Twelve L-shaped grooves 318 are evenly distributed on the outer wall of the graphite base 202. Twelve sliding rod bases 313 are installed on the inner bottom wall of the graphite base 202. A sliding rod 314 is slidably connected inside the sliding plate 310. The bottom of the sliding rod 314 is fixedly connected to the top of the sliding rod base 313. A limit plate 315 is installed on the top of the sliding rod 314. The end of the slide bar 314 near the slide bar 316 is hinged to the pressure bar 316 via a pin. The pressure bar 316 passes through the L-shaped groove 318, and the outer side wall of the pressure bar 316 is slidably connected to the inner side wall of the L-shaped groove 318. The end of the pressure bar 316 away from the slide plate 310 is equipped with an end ball 317. Through the setting of the slide bar base 313, the slide bar 314 and the limiting plate 315, the movement of the slide plate 310 is more stable, which improves the stability of the device. Through the setting of the end ball 317, the pressure bar 316 is prevented from slipping and injuring the arm when it rebounds upward, which improves the safety of the device.

[0031] In one embodiment, the top of the graphite base 202 is provided with 12 slots 207 evenly distributed, the slots 207 being located directly above the limiting block 307. The top of the graphite base 202 is provided with 12 graphite heating blocks 203, and the bottom of the graphite heating block 203 is installed with an insert 206. The insert 206 is slidably connected to the slots 207. The slots 207 and the insert 206 facilitate the fixation of the bottom of the graphite heating block 203.

[0032] In one embodiment, a docking block 204 is installed on one side of the graphite heating block 203, and a docking groove 205 is provided on the side of the graphite heating block 203 away from the docking block 204. The docking block 204 and the docking groove 205 facilitate the fixing of the side of the graphite heating block 203.

[0033] In one embodiment, a switch 105 is installed on the outer wall of the heating box 101. The switch 105 is electrically connected to the power-on base 201. The switch 105 facilitates the opening and closing of the power-on base 201.

[0034] In operation, this invention involves inserting the mating block 204 into the mating groove 205 of the graphite heating block 203. The connection between the mating block 204 and the mating groove 205 completes the splicing of the graphite heating blocks 203. The graphite heating block 203 is then inserted into the slot 207 via the insert block 206. Since the bottom of the insert block 206 and the top of the limiting block 307 are both sloped and their shapes fit each other, when the insert block 206 moves downwards, the limiting blocks 307 on both sides are compressed and move to the sides. This causes the connecting rod 309 and the support rod 305 to move to the sides along the housing 301 and the sliding rod 303 via the slider 304. The spring 302 between the slider 304 and the housing 301 is subjected to... When the insert 206 is fully inserted into the graphite base 202, the triangular structure at the bottom of the insert 206 moves away from the limiting block 307. At this time, the spring 302 between the housing 301 and the slider 304 generates a reaction force, causing the sliders 304 on both sides to move the limiting blocks 307 on both sides towards the middle through the support rod 305 and the connecting block 306, tightly clamping the two sides of the middle position of the insert 206. After the graphite heating blocks 203 are installed in sequence, push the push handle 104 to move the device to the appropriate position via the universal wheel 106. Place the object to be heated on the graphite chassis, pull the handle 103 to cover the top of the heating box 101 with the sealing cover 102, and control the operation. Switch 105 energizes the power base 201, which heats the graphite base 202 and graphite heating block 203 through resistance. If the graphite heating block 203 is damaged, the sealing cover 102 is opened, pressing the pressure rod 316. The pressure rod 316 moves downwards within the L-shaped groove 318. The pressure rod 316 drives the sliding plate 310 to apply pressure to the sliders 304 on both sides via the connecting rod 309, causing the sliders 304 to move laterally along the housing 301. The sliders 304 simultaneously move the support rod 305, connecting block 306, and limiting block 307 to both sides. When the pressure rod 316 reaches the bottom of the L-shaped groove 318, it moves along the L-shaped groove via the pin. When the bottom of the groove 318 moves horizontally, one end of the pressure rod 316 is limited by the horizontal section of the L-shaped groove 318. The limiting blocks 307 clamped at both ends of the insert block 206 are separated, allowing the damaged graphite heating block 203 to be moved upward through the docking groove 205 and removed. After the new graphite heating block 203 is replaced, the pressure rod 316 is moved to the vertical section along the horizontal section of the L-shaped groove 318. Through the linkage of the spring 302, the slider 304 and the transmission rod, the slide plate 310 drives the pressure rod 316 to move upward and return to its original position. The limiting blocks 307 on both sides return to the clamping state, making it easy to fix the replaced graphite heating block 203.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
